Paul Krugman – The New York Times

Posted: October 4, 2016 at 1:35 pm

Paul Krugman joined The New York Times in 1999 as an Op-Ed columnist. He is distinguished professor in the Graduate Center Economics Ph.D. program and distinguished scholar at the Luxembourg Income Study Center at the City University of New York. In addition, he is professor emeritus of Princeton Universitys Woodrow Wilson School.

In 2008, Mr. Krugman was the sole recipient of the Nobel Memorial Prize in Economic Sciences for his work on international trade theory.

Mr. Krugman received his B.A. from Yale University in 1974 and his Ph.D. from M.I.T. in 1977. He has taught at Yale, M.I.T. and Stanford. At M.I.T. he became the Ford International Professor of Economics.

Mr. Krugman is the author or editor of 27 books and more than 200 papers in professional journals and edited volumes. His professional reputation rests largely on work in international trade and finance; he is one of the founders of the new trade theory, a major rethinking of the theory of international trade. In recognition of that work, in 1991 the American Economic Association awarded him its John Bates Clark medal. Mr. Krugmans current academic research is focused on economic and currency crises.

At the same time, Mr. Krugman has written extensively for a broader public audience. Some of his articles on economic issues, originally published in Foreign Affairs, Harvard Business Review, Scientific American and other journals, are reprinted in Pop Internationalism and The Accidental Theorist.

His column appears every Monday and Friday. Read his blog, The Conscience of a Liberal, and follow him on Twitter.

8 Secrets to Achieving Financial Independence

Posted: at 1:34 pm

If you make $1 million a year from a job, you could lose your job any day. If you make the same $1 million from owning hotels, or businesses, no one can take that from you. Having a high income alone does not mean financial independence.. Robin Bartholick, Getty Images

Most people believe the key to wealth is a high-paying job. Yes, it's easier to amass assets if you have more money coming in each month, but the true secret to increasing your net worth is to spend less than you make. It is a cliche; but it is the fundamental, absolute, non-negotiable reality of money. To escape this trap, you need to understand that income is not wealth.

What is wealth? My personal definition: Wealth is the part of your net worth (assets minus liabilities) that generates capital gains, income, and dividends without your labor. If you are a Doctor or Lawyer, you need to put in long hours after years of specialty training and higher education to get a paycheck. On the other hand, if you have a portfolio of private businesses, car washes, parking garages, stocks, bonds, mutual funds, real estate, patents, trademarks, and other cash generators, you could sit by the pool. The real value, of course, is that you could maintain your lifestyle even if you were disabled or unable to continue working at your primary occupation. Better yet, unlike a salaried employee, wealth can't fire you you have to squander it. It's far easier to lose a job that wipes out a well-constructed portfolio.

The level of your wealth should be measured by the length of time you could maintain your standard of living without an additional paycheck. In other words, if you had to stop working right now, how long could you keep up your purchasing pattern for cars, clothing, music lessons, college tuition, video games, etc.? The average person isn't educated in this truth, which is why the more and more they earn, they are left wondering why financial independence and security continue to allude them, always seemingly just out of grasp.

Oceania refers to Australia and to those Pacific islands situated between (and including) the Hawaiian archipelago and the Marianas Islands in the north, Easter Island in the east, New Zealand in the south, and New Guinea in the west. These boundaries are essentially ethnological and, in some respects, arbitrary. Although only a few scholars think that there have been significant human interchangesbiological or culturalbetween this region and the Americas, the western boundary is anything but sharp. Prior to the colonial era people of the Marianas and West Carolines seem to have had little or nothing in common with the Ryukyuans to the north, but their past relations with the Philippines are clearly demonstrable in language, culture, and physique. Links between New Guinea and islands west of it are even more evident; in fact, the Moluccas constitute something of a transition zone.

Our concern with the physical environment of Oceania is twofold. First of all, we are interested in those environmental features which have had some relevance to the social behavior of peoples with nonmetallic technologies, nonurban settlement patterns, and largely nonscientific ideologies. For such peoples the presence or absence of mineral deposits, deep harbors, or natural grazing pastures was largely irrelevant, but these very factors did become relevant to native behavior through the intermediacy of alien whites and Asians.

For the native Oceanians the region provided a wide range of natural assets as well as a formidable array of liabilities (Oliver 1951). In Australia, the climate nowhere reached such extremes as to render any large zone entirely uninhabitable. In fact, the populace tended to concentrate, regardless of climate, in places where natural foods were most abundant, i.e., in the humid and tropical north as well as in the temperate southeast. The natural foods relied upon by the hunting and gathering peoples included kangaroos, cassowaries, snakes, lizards, turtles, fish, grubs, fruits, roots, seedsin fact, almost everything the land and water produced that was even conceivably edible. The Australians direct and, one might say, indiscriminately total reliance upon the continents given resources for their subsistence may help to explain many of the similarities among aboriginal cultures noted by most students. But by the same token, local differences in the kinds and quantities of those resources also resulted in the development of some regional differences in other domains of cultural life.

Unlike the Australians, other islanders were primarily gardeners; hence the factors of rainfall, topography, and soil were of more immediate importance than direct availability of wild plants and animals. The islands of Oceania may be divided into several more or less distinctive types in regard to these features.

The continental islands are New Guinea, New Britain, New Ireland, Bougainville, and the mountainous archipelagoes which culminate in Fiji in the east and New Zealand in the south. These islands rise from a vast submarine platform which extends outward from Asia. The bold relief and wide,diversity of soil types, coupled with local differences in climate, have produced numerous sharply distinctive natural areas: bleak mountain summits, fern-forested uplands, grassy plateaus and high valleys, magnificent rain forests, scrubby jungles, riverine swamps, foothills, sandy coastal shelves, flat offshore reef islets, etc. This geographic diversity has contributed to the cultural diversity which is a hallmark of this portion of Oceania.

The remaining islands of Oceania are much smaller, more dispersed, and consist of just three basic landforms: high volcanic peaks, low coralline atolls, and raised-coral pancakesor combinations of these, each affected by differences in age, weathering, and climate. In addition, the proximity to supplies of marine food has served, in some places, to reduce the direct dependence upon soil.

Opportunities for formulating and testing hypotheses about human behavior are enhanced by the insular nature of the region, which provides the researcher with laboratorylike controls found in few other regions of the world. In island Oceania wide stretches of ocean or hazardous natural barriers helped to isolate human communities from one another for years or even centuries at a stretch; and the Australians, although in contact with each other, were themselves more or less isolated from the rest of humanity for many thousands of years. But before describing the uses that social scientists have made of data obtained in Oceania, we shall sketch the outline of mankinds history in the area, as reconstructed by archeologists, linguists, and ethnologists. This reconstruction is, of course, immensely interesting in itself as a chronicle of some fascinating chapters of human history; but its relevance in this article consists of the light it can shed about some of the events whose sequels provide social science with such varied and amenable resources for research.

Skeletal fragments and crude stone artifacts found on Java demonstrate that tool-making hominids inhabited at least the Greater Sunda Islands as early as the first interglacial period, but the oldest human remains yet found in Oceania (i.e., in Australia) go back no further than ten to fourteen millennia. Since archeology is just beginning in Australia and New Guinea, it is reasonable to anticipate some deepening of their chronologies in due course. But it is interesting and probably indicative that no excavations carried out elsewhere in Oceania have revealed traces of humanity dating back beyond 3,500 years ago. It is simply unlikely that much earlier than that there were any boats in the western Pacific capable of reaching such places as Hawaii, New Zealand, or even Fiji. And as for movements from the east, I stated at the outset my firm belief that Oceanias populations and cultures derived ultimately from the southern and eastern shores of Asia. There may well have been added a few genes and a few culture traits from the Americas, but if such were the case they were relatively late and comparatively insignificant.

There is no demonstrable basis for linking race with intellectual potential, but raceor at least its visible criteriahas some relevance to the student of social behavior in Oceania. It has figured, for example, in natives estimates of each other; and it has greatly influenced whites attitudes towards natives (e.g., the light-skinned, straight-haired peoples of Polynesia have by and large been treated with less contempt than their darker-skinned neighbors of Australia and the western islands). But knowledge of the genetic composition of Oceanias population could conceivably also provide helpful clues concerning culture history.

Few systematic studies of race have been carried out in Oceania, save in Australia and southeastern Polynesia, and the specialists differ in their interpretations of the findings. Although there is nearly universal agreement upon Asias having been the source of Oceanias populations, there is no consensus concerning the identity or the sequence of the several genetic strains that are evidently present in these populations.

There is a difference of opinion even with respect to the make-up of Australias quite distinctive aboriginal populationthe dark-skinned, curly-(not frizzly) haired individuals with massive browridges and low, broad noses. On the basis of some marked regional differences in physical features, some specialists posit three separate racial components: a short-statured negroid type; a larger-bodied, lighter-pigmented, more hirsute type reminiscent of the Ainu of northern Japan; and a more slender, dark-skinned, curly-haired type similar to the Veddas of Ceylon. According to this view, these three types arrived in separate waves or tricklesand have interbred somewhat, but not homogeneously, during the succeeding millennia. According to another view, the aborigines were of the same race to begin with and have developed their regional differences since arrival on the subcontinent. For the social scientist these contrary views are not without relevance: if the population can be shown to be tri-hybrid in origin, researches will logically focus on explaining the many cultural similarities found throughout the continent and vice versa.

For the rest of Oceania the racial composition is even more complex and variously interpreted. The archipelagoes containing the so-called continental islands, from New Guinea to New Caledonia and Fiji (but not New Zealand), are inhabited mainly by populations with frizzier hair and somewhat darker skin colors than possessed by their neighbors to the north, east, and south. This circumstance has led to the area being labeled Melanesia (black islands), a term which is rather inaccurate and has proved to be mischievously misleading. In the first place, although there are many dark brown and even coal black populations within Melanesia, there are also many others no more heavily pigmented than, say, natives of Tahiti or Tonga. Second, this regional division based on somatic criteria has been arbitrarily perpetuated by ethnologists in the cultural sphere.

Within Melanesia the range of racial types (or subtypes) is very wide. Stature ranges from pygmoid to tall, pigmentation from light copper to jet black, prognathism from absent to pronounced, etc., and there are no obvious correlations, direct or inverse, between these attributes. Some populations look remarkably Australian (except for hair forms), others like frizzly-haired Mongoloids, and still others (with light pigmentation and high, beaklike noses) resemble no other physical types anywhere.

Elsewhere in Oceaniain the far-flung archipelagoes of Micronesia and Polynesiaphysical types tend to be more uniform: the population becomes more Mongoloid and less Negroid; but the similarities (and differences) are not distributed in clear enough patterns to provide the specialists with unambiguous historical clues.

In fact, there is enough ambiguity in the racial data available for Oceania to permit any number of different historical reconstructions (including one that posits an American Indian component: Asia, after all, is the ultimate source of Oceanians and Amerindians). One reconstruction, derived from the tri-hybrid Australian scheme, proposes a succession of racial immigrations of the following order: Ainoid, Pygmy Negritoid, Veddoid, and Mongoloid. Another scheme includes Australoids (undifferentiated), both pygmy and full-statured Negroids, and Mongoloids. Still others (for somewhat gratuitous reasons) believe a so-called Caucasoid element to be present, especially in the populations of Polynesia.

Weighing all these alternatives, it seems least uncertain, and geographically most logical, that Australia and Melanesia were the first to be peopled, and by some combination of Negroids (short, or short and tall) and Australoids (or Ainoids-Veddoids); and that these separate strains interbred in varying degrees in different places. Nor is it unreasonable to believe that Mongoloid strains were the last to appear, leaving their genetic traces along the route, or routes.

It is unlikely that archeologists will ever turn up enough skeletal remains to permit a detailed reconstruction of Oceanias whole racial history, and social scientists searching for precise and longrange historical guidelines cannot expect much help from this direction. However, the small sizes and relatively great isolation of so many of Oceanias populations render them ideal laboratories for studying microevolutionary phenomena e.g., the relationship between physical variance, on the one hand, and social structure, ecology, or epidemiology, on the other. Here, indeed, are to be found ideal opportunities for anthropologists to practice what they preach about their concern with both cultural and biological aspects of mankind.

The languages spoken by the Oceanians comprise three great categories: Australian, Austronesian, and non-Austronesian (Capell 1962; Klieneberger 1957). Quite apart from the intrinsic interest of the subject matter, the study of these languages, both descriptively and historically, is relevant to social science inquiry. Not only is knowledge of the local vernacular indispensable for all but the most superficial field research in any Oceanic society, but ethnographersand especially those who have worked in Oceaniawould probably agree that a societys language is a very important part of its cultural inventory. And on the historical side, findings about language relationships, genetic and acculturational, provide the best evidence we have for culture-historical reconstruction in generaland hence for comparative studies of social behavior.

The native languages of Australia (including Tasmania) differ markedly among themselves in structure and vocabulary, but their outstanding student, Arthur Capell, considers them members of the same family (1956). Numerous attempts have been made to trace their relationships outside Australia; so far these efforts have proved unconvincing, but it would not be surprising if future research were to turn up some links with non-Austronesian languages of neighboring New Guinea.

Prior to the spread of English, Spanish, and French in recent centuries, Austronesian was the most far-flung family of languages in the world: its speakers were spread from Formosa and Malaya to Hawaii, Easter Island, and New Zealand (one of its western languages even became established on Madagascar). Outside Australia and certain parts of the continental islands, all the languages of Oceania are to be classified within this great family.

For many decades it was the conventional practice of linguists to subdivide this family into four major (and implicitly more or less coordinate) branches:Indonesian (including Malay and all the Austronesian languages of the Philippines, the Sunda Islands, the Moluccas, etc., along with Malagasy (Madagascar), Cham (Cambodia), Li (Hainan),Jarai (Vietnam), Lati (southwest China), etc.;Micronesian (all the languages of Palau, the Marianas Islands, Caroline Islands, Marshall Islands, and Gilbert Islands); Polynesian (all the languages of Hawaii, Tonga, Samoa, New Zealand, Tahiti, Easter Island, etc.); and Melanesian (all Austronesian languages of New Guinea, the Solomon Islands, New Hebrides, New Caledonia, Fijiexcept for certain Polynesian language outlierswithin the geographic zone of Melanesia). Thus the practice of subdividing Oceania according to so-called racial (Melanesia, black islands) or geographic criteria (Micronesia, small islandsPolynesia, many islands) was somewhat arbitrarily carried over into linguistic classification and, as will be seen, into general cultural classification as well.

Recent developments in linguistic science, including lexicostatistics and new methods of data processing, have stimulated a reappraisal of this conventional scheme (Capell 1962; Grace 1964).There is anything but consensus among the many linguists now studying Austronesiansome depend almost wholly on lexical data for their results;others insist that grammatical considerations must also be taken into accountbut the older fourclass scheme has been generally abandoned. It is now acknowledged that the languages of the Marianas Islands, Palau, and Yap are closer to those of the Philippines than to any in Oceania itself. There is also common agreement that the several Polynesian languages (or dialects) are far too alike to justify placing them in a genetic position coordinate with the many widely varying languages of Melanesia. It is in connection with the latter that the specialists are in least agreement. According to one view they remain something of a genetically separate unit more or less coordinate with a comparable unit of Indonesian while in another scheme they are classified into a dozen or more units of the subfamily order of branching. Alsoand this has a direct bearing on long-range perspectives of social changesome writers view the Austronesian languages of Melanesia as fusions of the areas numerous aboriginal(and non-Austronesian) languages with immigrant (and, implicitly, quite uniform) Austronesian tongues: this is the pidginization theory, so called by analogy with present-day Melanesian pidgin, the contact language between Oceanians and whites throughout most of Melanesia. This view has been sharply challenged, both on linguistic and culture-historical grounds.

In fact, among the Austronesian languages of Oceania it is only with respect to the closely interrelated Polynesian subgroup that historical relationships have been sufficiently established to provide the social scientist with bases for some controlled comparisons of social and cultural systems. One can better appreciate the attractive possibilities for this kind of research by taking note of the likelihood, suggested by lexicostatistics, that all the known Polynesian languages derive from a single language which began branching not much more than two thousand years ago, and that during their subsequent histories many of them had no contact with non-Polynesian speech.

The label non-Austronesian has been given to those languages of island Oceania not classifiable as Austronesian; they are to be found on New Guinea, New Britain, New Ireland, and the northwest Solomon Islands, as well as on Halmahera and other islands of eastern Indonesia. From their distributionmainly in the interiors of the large west Melanesian Islandsit has generally been assumed that they are survivors of the tongues spoken in this region before the spread of Austronesian. Unlike the Austronesian family and the languages of Australia, the non-Austronesian languages have so far resisted the efforts of linguists to link them into a single genetically interrelated unit, although they do not appear to be quite so fragmented as was once believed. In New Guinea, for example, linguists have discovered in the eastern highlands a very extensive stock comprising some 750,000 speakers (Capell 1962); other such unities are likely to emerge as more professional linguists turn their attention to parts of Oceania where the native languages have not even been recorded, much less studied.

Australian aborigines (Elkin 1938; Berndt 1965) got their food by hunting, fishing, and collecting;despite occasional contacts with Macassarese and Papuans they appear never to have adopted agriculture. And although they kept more or less tame dogs that helped them hunt larger game, they raised no animals for food. Men hunted (and fought) with spears, clubs, throwing sticks, or, in some areas, bows and arrows; women grubbed up roots and insects with digging sticks. Life was nomadic, in pursuit of widely scattered and seasonally variable food supplies; shelters were temporary, makeshift affairs. Some of the artifacts were fashioned out of stone, bone, and shell, but plants provided the materials for most objects of daily life.

It has been estimated that at the time of initial European colonization some two hundred years ago, there were no more than about 300,000 people inhabiting Australiaprobably a fairly stable figure in view of their seemingly unchanging technology and their millennia-long residence. It is not unlikely that the distribution of the population had also reached a point of stability in adjustment to the continents several geographic zones, with the heaviest concentrations in the temperate southeast and tropical north and the lightest in the arid interior. Some three hundred languages are said to have been spoken in Australia, but these were not necessarily contiguous with cultural or political distinctions.

The nuclear family, modally if not normatively monogamous, was the basic residential unit of society. In some areas, and during certain parts of the natural seasonal cycle, individual families traveled separately, and although males and females contributed differently, food was usually shared. When the availability of food permitted, but also for social and ritual purposes, several families congregated into bands (or hordes)of various sizes and degrees of integration.

In addition to families and bands, Australian societies were divided into various other kinds of social units based on locality, kinship, age, and sex or combinations of these factors. One relatively simple and fairly widespread kinship structure consisted of unilinear and exogamous moieties. Societies were sometimes divided into four or eight such parts. In the view of some analysts these arrangements functioned mainly to regulate marriages, while other writers consider them to be classificacation devices for the convenient ordering of ones numerous kinfolki.e., all other members of ones community.

The factor of age also received emphasis in almost all aboriginal societies. Particularly for males, the cycle of growing up and aging was associated with a series of ritual events. These were carried out within the context of localized all-male sodality that was stratified into more or less agegraded subgroups. Some of these rituals included extreme forms of body mutilation (e.g., subincision of the penis) along with ceremonial dances and recitations of great religious depth and drama. The form and content of these rituals, along with their theological connotations and their social functions, varied considerably from place to place; but they were widespread enough and similar enough to be considered a very characteristicbut of course, not distinctivefeature of aboriginal Australian culture.

Another characteristic feature of Australian life was the absence of anything approaching occupational specialization. Individual differences in skill and knowledge and stamina were recognized, but expert hunters, warriors, artists, magicians, flintknappers, etc., were not relieved of the ordinary chores of subsistence, and they received few material rewards for their specialties. Some individuals undoubtedly produced goods that were surplus to their own families subsistence needssuch things as stone spear points, cordage, mineral pigmentsor benefited from occasional windfalls of meat or fish. The limited local exchange and long-distance trade of these goods were usually carried out within the context of kinship and with some ceremonial elaboration. However, there were probably no bands capable of producing enough over-all surplus to sustain full-time specialists of any kind.

Perhaps the most prestigious of skills was the ability to chant from memory the interminable myths, prayers, and formulas which formed indispensable parts of various rituals. Individuals possessing this skill who had also moved up through the ranks of the age-graded mens sodalities achieved a status that commanded some measure of authority in community affairs. Compared, however, with most other societies in Oceania, the institution alization of authority in aboriginal societies was not very developed.

No aspect of Australian life has attracted more scientific attention than the so-called religious beliefs and practices. Living, as the aborigines do, in symbiosis with their physical environment, they have animated it so anthropomorphically and so comprehensively that their perceptions of the universe appear to contain no boundaries between mankind and the actual or imagined populace of nature. One of their most widespread beliefs, for example, consists of linking certain animals and plantsgenerically or individuallywith each of their enduring social units or categories. Such linkages are usually conceived of in terms of kinship and not infrequently involve restrictions against eating or rituals aimed at magical increase of the species involved. In some places even mountains, pools, stars, thunder, rain, and sneezing are either individually or generically assimilated into the social structure. The myths and rituals embodying these beliefs are as diverse and bizarre as they are long and dramatic. Fertilityof nature and of humanityis a theme which runs through many of them; and they are enacted through songlike recitation, dance, and instrumental music.

Finally, this brief inventory of institutions would be incomplete without mention of the graphic art of aboriginal Australia. Students have only recently begun to study the rich domain of painting, carving, and engravingnaturalistic and abstract, public and esoteric. Although these deserve serious enough attention on artistic grounds alone, their apparent associations with myth and ritual make them intriguing subjects for social science as well.

As noted earlier, agriculture was the basis of subsistence throughout all of island Oceania (Oliver 1951).Even on certain of those arid atoll islets where soil is lacking, natives laboriously imported soil for gardens (Barrau 1958). In places dependent mainly on self-propagating tree crops some effort was occasionally spent in protecting and tending the plants, and some supplementary gardening was usually practiced as well. The main tree crops of the islands were coconuts, sago, breadfruit, pandanus, and bananas. The first European visitors found coconut palms growing on nearly every inhabited island except Easter Island, New Zealand, and Chatham Island. These trees thrive best in lower altitudes near the coasts and provided islanders with food, drink, oil, containers, fibers, thatch, and construction wood. Sago palms grow semiwild in many swampy areas, particularly on the larger continental islands; the starch extracted from the palms pith was the staple food in many riverine and coastal communities. Breadfruit is most prolific in the volcanic soils of the central and eastern islands; although fruiting only seasonally, this tree produces bounteously and requires little care. Some varieties of the pandanus, or screw pine, produce a fruit which can be made partly edible and which serves only as a famine food on richer islands but is the main vegetable food on some of the arid atolls. Bananas (including plantains), which grow in most of the moist tropical areas, varied widely in culinary importance, from a staple food to an occasional supplementary one.

Of the root crops, both wet-land and dry-land varieties of taro were cultivated; yams were grown widely both for food and for purposes of display;and sweet potatoes were adapted to poorer soils and cooler climates.

The islanders supplemented these crops with wild roots, stems, shoots, fruit, and leaves. The only part of Oceania in which natives cultivated rice was in the Marianas, another trait linking these islands with the Philippines.

Each of the vegetable staples required different production techniques and resulted in a wide range of cultural variations. Sago, for example, could be collected at any time of the year and was preserved by a laborious process. In contrast, breadfruit required little processing but fruited only once or twice a year and remained edible only in a fermented state.

In comparison with the Australians, most Oceanian islanders spent little time hunting. A noteworthy exception occurred in New Zealand, where early inhabitants hunted to extinction the giant moa, a large, flightless, ostrichlike bird. On the other hand, fishing was a major activity wherever marine resources permitted. Streams, rivers, reefs, lagoons, and open seas were harvested by means of an extraordinary variety of tools, watercraft, and techniques. As in the case of agriculture, differences in emphasis on fishing together with differences in fishing techniques were reflected in other cultural domainsin religious beliefs and ritual as well as in the social structure of households and communities.

Canoes have played a central role in the lives of Oceanians, and they have been used for fishing, everyday transport, and, prehistoric ally, in the peopling of this world of islands. Some of the riverine and coastal peoples of New Guinea found shallow dugouts adequate for their purposes of moving about in calm waters, but most other islanders depended upon outrigger canoes or deep-hulled plankbuilt boats. Although some elements of this complex reflect the common southeast Asian origin of Oceanias seagoing heritage, there has developed a rich variety of local specialtiesin boat construction, ornamentation, and handling, as well as in navigational principles and skills.

In many places the building and handling of a big canoe was an event of social importance, being one of the few instances of large-scale coordinated activity. For the social scientist these occasions reveal otherwise unstated premises regarding division of labor, authority, and exchange. In fact, in seagoing societies such as Tahiti the nomenclature applied to the various parts of their larger canoes was a metaphoric summary of the nativesimage of their political relations.

Like Australians, the Oceanian islanders kept dogsfor pets, hunting aids, and sometimes for food. Most households also kept a few fowlifkept is appropriate for the rather aimless relationship in which the fowl were neither fed nor eaten with any regularity. It was only on remote Easter Island that fowl became important in native economy and in ritual. Wherever islanders managed to introduce and keep them alive, pigs became much more important than dogs or fowl. They were eaten at feasts and used in ceremonial exchanges. In fact, so highly were pigs valued that in some societies they became the prime means and measure of political ascendancy.

In societies like these, where food occupies such a dominant positionin productive energy, in social interaction, in hierarchies of value, in cult focus, in symbolic expression, and so forththe cooking and eating of a meal may provide social science with some of its most rewarding data. In this connection, then, it should be noted that techniques of food preparation vary within societies and among societies. Cooking was everywhere important, although some fish and plant foods were occasionally eaten raw. Cooking itself varied from simple roasting and pot boiling to large-scale baking in community-size earth ovens. Even the most elaborate Hawaiian or Samoan menus and recipes did not compare with those of Asia, but in many places men (festal cooking was nearly everywhere done by males) knew how to prepare puddings combining many ingredients in various proportions.

Next to water the only beverage universally imbibed was the liquid of unripe coconutsat least where coconut palms grew. On many islands in the central and eastern Pacific natives drank kava (or ava, etc.), a mildly narcotic liquid made from the root of a cultivated pepper plant. On some islands (e.g., Fiji, Tonga, and Samoa) kava drinking reached a point of high ceremonial elaboration.These ceremonials served to express and reinforce community integration and political status. West of the kava-drinking part of Oceania, and barely overlapping it, were areas of betel chewing extending on into the south Asian mainland. In these areas betel chewing did not become as ceremonialized as kava drinking did elsewhere, but its use throughout the populations was more widespread.

Plants were the source of nearly all the cordage and textiles made in island Oceania; loom weaving was restricted to the Marianas and West Carolines, but hand plaiting developed in some places to the level of a fine art.

Matwork and barkcloth were the chief materials out of which most clothing, floor covering, bedding, sails, and temporary shelters were made. In some places finely textured mats and barkcloths circulated as highly valued objects in networks of redistribution and intergroup exchange. Houses differed widely in shape and size; some were built to accommodate only a small family, while others were spacious enough for hundreds of people. Comparison of local differences can provide insights into human inventiveness and the processes of adaptation and also into historical relationships, but the nature of Oceanian housebuilding has even more direct relevance to the social scientist, inasmuch as most such enterprises involve the actions of large numbers of people contributing materials and services according to conventional social patterns. House architecture often provides valuable insights into the residents views about their social universeviews which might otherwise remain inexplicit. The residences, for example, very rarely contain inner partitions, but for the occupants internal space is divided into functionally and symbolically distinct rooms; in fact, in many places a house provides space for the living and for the dead, for spirits as well as mortals.

Public structures of many types and utilizing varied construction materials were built in island Oceania. They served a wide variety of uses: clan refuges, exclusive mens clubhouses, secular meeting places, temples, forts, theaters, athletic arenas, lovers trysts, craftsmens workshopsin fact, nearly everything but market places for buying and selling.

Within recent years the graphic and plastic arts of Oceania have aroused keen interest among art historians and collectors. The skillfully executed masks, ceremonial implements, idols, and so on are also of interest to the social scientist because of their relevance to social behavior. Designs, for example, often express magical intent or supernaturally protect ownership or clan unity. Or, the roughly shaped, grotesque figure may in faith be the terrestrial resting place of a powerful and handsome god. We cannot begin to describe the great variety in materials, techniques, and designs found in Oceanic art objects, but the situation is not as chaotic as a rapid walk through a museum might lead one to believe. In fact, some surveys by anthropologically oriented experts have begun to delineate for all Oceania a manageably small number of distinctive artistic traditions, thereby providing social scientists with some new and stimulating possibilities for investigation (Linton &Wingert 1946; Guiart 1963a).

In the foregoing discussion we have dwelt mainly on what islanders did and what they made in connection with daily living. However, it should at least be pointed out that islanders did not go about the business of making a living without reflection, in slavish response to custom On certain occasions islanders undoubtedly acted because of time-honored and sanctioned precedent, but their actions were more frequently pragmatic. Perhaps the many different and often difficult kinds of physical environments met with in the course of their histories in Oceania had something to do with this, by placing a premium on flexibility and adaptability. Many of their actions were based on premises that we would call magical, but this is not to deny the presence of a scientificattitude toward their environment.

As for the magical ingredient of their thinking, neither its logic (homeopathic, sympathetic) nor its content (animism, animatism) is distinctively Oceanian in any essential way.

Turning now to the islanders pre-European social behavior, we begin by acknowledging our inability to generalize about the region as a whole or about large segments of it. A great deal is known about the social life of certain island peoples, but there are many more societies about which nothing, or next to nothing, is knownwith no prospect of ever gaining such knowledge in many cases because the islanders native forms of society have completely disappeared under the impact of alien influences. And even with what is knownand among the studies of single island societies there are some of the worlds most complete ethnographiesscholars are just beginning to push beyond local description toward wider regional typologies of the kind formulated for Australia (e.g.,Hogbin & Wedgwood 1953; Sahlins 1958; Goldman 1960).

Settlement patterns. Although many excellent ethnographic descriptions treat patterns of residence, few attempts have been made at the comparative study of settlement patterns. Perhaps the most typical form of settlement pattern in the islandsthis is an impression, not an established factis the small four-to-five household hamlet or neighborhood; but there are also numerous instances of dispersed homesteads, at one extreme, and of densely settled villages, at the other. In this connection it is an interesting fact that some of the largest and most tightly integrated political units e.g., on Tongacomprised widely scattered homesteads. Villages rarely contained more than a thousand inhabitants; the average number was probably more like two to three hundred. Some of the larger villages were to be found alongside rivers or lagoons, but they have been noted in other kinds of settings as well. In some instances residences were clustered near the public placestemples, council houses, dance grounds, mens clubhouses, etc.; in others the public places and dwellings were kept far apart. Some settlements were surrounded by stockades; others lacked defensive constructions despite their involvement in periodic warfare.

Family. The nuclear family was certainly the most ubiquitous type of social group in island Oceania, although polygyny was permitted in most societies. Polygyny was practiced by only the most affluenti.e., those men who could afford the bride price or other expenditures associated with marriagebut in some of the wealthiest societies even the most influential leaders had only one official wife at a time.

There is evidence that polyandry was formerly practiced in some Polynesian-speaking societies, but little or nothing is known about its wider social contexts.

With regard to matrimonial rules of residence, couples tended to reside near or with the husbands male patrilineal kinsmen. The next most prevalent pattern among those societies surveyed (Murdock 1957) was residence near the wifes female matrilineal kinsmen; but in several other societies these alternatives were about equally favored. Still other alternatives have been recorded for other societies, e.g., residing close to the husbands matrilineal kinsmen.

Even in societies allegedly ignorant of the males biological role in reproduction (Malinowski 1922) social roles of maternity and paternity were institutionalized, although the nature of such roles, both in theory and practice, varied widely. At one extreme were those societies in which both mother and father shared the job of nurturing and socializing their children, with property being transmitted through both parents. In contrast, there were some other societies wherein the sociological father had little or nothing to do with his childrens specific upbringing or equipping beyond contributing generally to the domestic commissary. In between these extremes were numerous permutations, usually reflecting each societys general conceptualization of kinship.

Two other fairly characteristicbut of course not distinctivefeatures of island life had to do with membership in the family group. In some societies, even when a child was recognized as the biological offspring of a man, the latter was called upon to validate the relationship before it could become socially operative. The other feature of widespread occurrence was the facility and the popularity of adoption, especially practiced in the eastern parts of the region.

It is our impression that nuclear familiesplus one or two other dependent relativesconstituted the most typical residential units in the majority of island societies, but there were numerous variants. In some places households were much larger and consisted of composite familieseither polygynous, stem, joint fraternal, joint sororal, or some other type. In other places a man spent most of his sleeping and waking hours in his community mens house, visiting his wife and children in their household only on occasion. Variations in household composition were wide, as were variations in collective activity, in kinds and amounts of goods owned corporately, in symbols of unity, etc.; and all these facets of family and household life were surely related more or less directly to each societys more general institutionalization of kinship.

Although ties of kinship were not the only kind of social bond recognized and institutionalized in island societies, they were by all odds the most important. In most island societies, every member could claim (if not actually trace) some kinship tie with every other member. These kinship categories each implied some normative pattern of behavior no matter how attenuated by the remoteness of the tie or the influence of extraneous factors such as locality and social stratification. Indeed, relations across tribal and societal boundaries were more often than not dominated by considerations of kinship.

Within the context of all-inclusive kinship, which characterized most island societies, there were, however, some wide differences in the actual groupings of kinfolk. In size such groups varied from small, sharply defined units to large ones with vague or overlapping boundaries. Some groups were bilateral in descent, others patrilineal or matrilineal. Some were stringently exogamous, while in others membership appears to have played no direct role in choice of mate. In some societies, like certain ones of highland New Guinea, groups formed by the male members of patrilineages were all-importantmaritally, residentially, economically, politically, and ritually. In other places actual groups of kinsmenqua kinsmenwere scarcely discernible, either interactionally or symbolically.

What little collation has been done in this domain of social structure indicates that patrilineally structured groups predominated in New Guinea and matrilineal ones in central Micronesia and in parts of western Melanesia. Throughout most of Polynesia and in the rest of Micronesia the aggregates of kinfolk defined by common ownership of land and other valuables were ideally more nonunilinear in membership, although in actuality patrilateral ties preponderated. Elsewhere, in central and eastern Melanesia, there existed in close juxtaposition all these variants of kinship structure (Murdock 1957).

Other social groups. In most island societies there were other kinds of associational ties which crosscut those of kinshipties of coevality, of cult commitment, of occupation, and, most important, of coresidence.

Age itself was less influential in island Oceania than it was in Australia. Authority and privilege did derive from seniority in some societiesespecially in some of those with patrilineal kin groups but coevality as an organizing principle was only sporadically important (e.g., in parts of New Guinea and Melanesia, where painful male initiation rites served to usher boys into cult-focused mens clubs).

In many island societies, as throughout Australia, the mythical charters which rationalized and legitimatized kin groupings were embodied in congregational ritual. But, in addition, many island societies incorporated cult groups whose members were only incidentally kinfolk. Examples of such were the masoniclike mens clubs of New Hebrides and the intertribal Dionysiac Arioi sect of eastern Polynesia.

Occupational specialization was more marked in island Oceania than in Australia, but groupings of specialists were rare. In Samoa there were guildsof housebuilders, and in some other island societies one might discern the beginnings of other craft guilds or of schools of savant-priests, but that is about all.

Political organization. In most island societies neighbors were also kinfolkin fact or by nationalizationbut coresidence was often more influential than kinship as a basis for association. On the other hand, the size and degree of integration of such political units varied widely. At one extreme were numerous societies having no collective-action groups larger than localized extended families. At the other extreme were a few Polynesian societies containing highly organized, territorially based tribal units with many thousands of members. In between, and most typical, were societies whose political units were conterminous with small village or neighborhood communities, or with clusters of such communities, averaging perhaps a few hundred citizens and rarely exceeding fifteen hundred.

Island political units differed not only in size but also in domain. Units for waging war varied from tightly knit regiments to undependable confederacies of separate kin groups. Actions for the maintenance of internal order ranged from comprehensive, centralized policing to uneasy interkingroup feuding, wherein the over-all leaders did little more than protect their own kin groups interests. In some places a political units members were all linked in redistributive networks involving frequent and copious flows of objects and services;in other places little or nothing was exchanged among the strata of social hierarchies. And finally, whereas in some societies the identities of the political units were symbolized and validated in influential myths and impressive ceremonies, in other places only the most discerning observer would have discovered clues to collective notions of unity.

Succession to political leadership was hereditary in some island societies, nonhereditary in others;and there were differences within each category. In instances of hereditary succession, the principle of patriliny predominated; and even in societies whose kinship groups were matrilineal political offices usually passed from male to male. However, there were a few recorded instances, mainly in Polynesia, of high political office devolving upon females.

Nonhereditary succession to political office characterized large portions of Melanesia. In what was perhaps its most distinctive variant, wealth was an important steppingstone to power. In such cases, however, the prestige upon which power was based derived not so much from accumulating valuables but rather from disposing of themin potlatchlike feasting or in conspicuous waste.

But many island societies may not be so exclusively typed: in some, individuals born to high office had also to prove themselves capable of exercising it; in other cases they had to vie for office with low-born individuals of outstanding ability. And in some societies these contrasting principles of succession served to maintain situations of unresolved internal conflict.

Relations between political units were of many different kinds. Hostility colored most such relations over the long run, but it was usually tempered either by periods of general truce or by only individual kin-group feuding. Moreover, even between traditionally hostile tribes it was customary for women to be exchanged and goods to be bartered. Some of the intertribal circuits extended over hundreds of miles, and while some of the transactions were conducted without direct contact between the principals (i.e., silent trade), othersincluding the famous kula trade of southeast New Guineainvolved mass expeditions and elaborate ceremonies (Malinowski 1922). Another institution typical of many parts of island Oceania was that of the trade partnershipi.e., a pact between two friends or kinsmen from separate political units providing reciprocal visiting and bartering rights even in periods of intertribal conflict.

Many societies in island Oceania were to some degree stratified, but the phenomenon was most highly institutionalized in Polynesia, notably in Hawaii, Tahiti, Samoa, and Tonga, where three or even four strata were distinguishable. In these societies class status derived almost wholly from birth and birth order, and for higher-ranking individuals class endogamy was so prescriptive that there developed castelike common-interest upper classes which cut across political boundaries. Political and ceremonial leadership were closely linked with class status, but ability sometimes outweighed birth, resulting occasionally in the relegation of highest-ranking persons to positions of little more than ceremonial pre-eminence (Sahlins 1958;Goldman 1960).

In view of the wide variety of cultural traditions and social structures found throughout island Oceania, it becomes next to impossible to generalize comprehensively about the behaviors of individuals in these societies. Individual life cycles, for example, were institutionalized in many different ways. In some societies the onset of puberty was marked by physical mutilation and community-wide ritual, in others it was virtually ignored. In some places the aged were revered and deferred to, in others they were socially devalued. Females were perhaps nowhere treated as chattel, but their social and ritual roles ranged from that of a magically polluted minor to that of a semidivine chieftainess. Even innovation received widely differing valuations, not only from society to society but within the same society as well. In some communities, for example, the invention of new graphic designs was discouraged while the composing of new songs was honored. Or, craft techniques remained rigidly traditional, while the discovery of new religious doctrines or magical formulas was socially rewarded. In fact, perhaps the only generalization one can make about islanders as individuals (and this in a manner both imprecise and impressionistic) is that in nearly all available descriptions of them they stood out as individualsas distinctive, at least partly autonomous persons, not as mere faceless units of this or that social aggregate.

Prior to the sixteenth century there may have been direct contacts between Oceania and Asian, or even American, high civilizations, although they were not enough to revolutionize native ways of life. But Magellans discovery of the Marianas Islands in 1521 ushered in a new era which is still going on and which is destined to transform most of the regions native societies.

During the four and a half centuries since Magellans voyage tens of thousands of Westerners (also Japanese, Chinese, and Indians) have visited or resided in Oceanianot to mention the millions now established in Australia, New Zealand, and Hawaii, and the additional hundreds of thousands who swept through the islands during World War II. Many Oceanians have also visited the outside world, but up to now their influences upon their own native communities have been minimal. With the exception of Australia, New Zealand, and Hawaii, where the process of Westernization has proceeded at a faster tempo, the history of culture contact in Oceania can be described in terms of five distinctive but overlapping phases.

(1)The phase of exploration began with Magellan and is still going on in parts of New Guinea. By 1830 the consequences of these visitations from the West were well underway, in the shape of depopulation (mainly through introduced disease) and murderous warfare (with the help of firearms).

(2)Whalers, traders, and missionaries commenced their operations about 1780, continuing until about 1850. (Spanish Catholic missionaries were active long before 1780 but only in the Marianas.) Depopulation and political turmoil continued during this phase and were accompanied by widespread collapse of indigenous religious institutions and of religion-sanctioned political structures.

(3)Around 1860, planters, labor recruiters, and merchants initiated change consequent upon the removal or shifting about of large segments of the male population for long periods of virtually forced labor, the introduction of money and cashcrop economy, and the heightened desire for Western manufactured goods.

(4)Foreign governments began to assert administrative control over island populations over a hundred years ago, but interference with native political structuresincluding total replacementwas most direct during the half century before World War II. This phase also witnessed an increase in the native population, mainly because of improved medical services and an increased flow of Westerners into parts of the region where mineral deposits were located.

(5)The events of World War ii served not only to speed up kinds of change already in process, including urbanization and money-based economy, but to stimulate other changes as well. The postwar improvement in interisland communication and transport gave rise to several dramatic developments. Locally inspired movements to weaken political ties with the overseas ruling metropolitan powers and to advocate strengthened interregional cultural ties are among these new developments, although they are not necessarily fundamental to change.

Despite the homogenizing effects of these several but predominantly Western influences, the various Oceanian societies retain a large measure of local variation. None are at exactly the same stage of Westernization: for example, one can contrast industrialized Nauru with the New Guinea population, only now exchanging stone tools for those of steel. And no two native societies have experienced the same mixture of Western influence: even in New Guinea, for example, a community near a large coconut plantation has adjusted very differently from one near a mine;and the Polynesians in French Tahiti have become quite different from their ethnic cousins in British Samoa.

Although there are increasingly pressing political reasons why the rest of the world should begin to know something about Papuans or Fijians or Samoans, our present concern is with Oceanias significance for social science in generalwith the research opportunities it has provided for formulating and testing universally valid methods and theories, and with the uses that have been made of such opportunities. The reaction, for example, by the natives of Bikini to resettlement away from their radiation-polluted home island is of course poignantly interesting and of some relevance to international politics; but study of this situation would have had little value for social science if its procedures had not provided possibilities for testing social science methods and making innovations in these methods and if its findings were not widely applicable (Mason 1957).

Oceania has offered social scientists a very wide variety of social and cultural systems, many of them so strikingly exotic as to require major accommodations in some aspects of Western-based social scientific thinking. In addition, even as late as a few decades ago, when trained social scientists began their study of this region, they were observing the end products of centuries or millennia of isolation from the rest of the world and even largely from one another. And third, the relatively small sizes, sharp boundaries, and (perhaps consequently) internal cultural homogeneity of most of these societies made it possible and indeed inevitable for individual observers to investigate the functional relationships of many domains of behaviornot just technology or kinship or art, but all three in themselves and in relation to each other.

Research into Oceanian ways of life began nearly two centuries ago, when men like Banks, Bligh, and the Forsters went beyond the mere recording of personal experiences and of native bizarreness to carry out more or less pointed inquiries into native institutions. Moreover, the reports contributed by such men were empirically significant to the beginnings of comparative sociology in Europe. For the next century and a quarter, as more and better descriptions of Oceanians ways of life came to be produced by missionaries, administrators, and other island residents, the professors back home were able to use these data to support theories or to compile vast syntheses (for example, Morgan, Durkheim, Frazer, Freud). But it was not until 1898 that social scientists left their armchairs to confront their subjects in person.

In that year the Cambridge anthropological expedition to the Torres Strait islands (between northern Queensland and New Guinea) took place and included such men as Haddon, Rivers, and Seligman. It was during this expedition that Rivers developed his genealogical method for recording kinship data, which has subsequently been such an indispensable tool in social anthropological research everywhere. Between this expedition and the outbreak of World War I amateur and more or less competent observers residing in the region continued to produce ethnographic accounts which were used by scholars in their compilations, but field research by trained social scientists was carried out by only a handful, notably Malinowski, Radcliffe-Brown, Thurnwald, Sarasin, Reche, Williamson, Poech, Haddon, and Rivers. It is probably fair to say that only the first three (and Rivers, to a lesser extent) produced publications from their Oceanian data that have been influential in the subsequent development of general social science theory and method.

Undoubtedly the outstanding landmark in social science research in Oceania was the work of Malinowski, whose monographs on the Trobriand Islanders have never been surpassed in ethnographic artistry. His studies ushered in a new world-wide approach to anthropological research that has come to be known as functionalism. Radcliffe-Brown drew upon his field experiences in Australia (and elsewhere) to produce essays that have led him to be identified as a cofounder of functional anthropology, although he himself disavowed the label. Through their teaching and writings these two men virtually dominated social anthropology throughout the interwar period; and their students, and students students, still hold most of the important teaching positions throughout the British Commonwealth.

In the interwar period more and more professionally trained social scientists went to Oceania to carry out sociologically and psychologically oriented research, and after World War II the influx reached flood proportions and is not now visibly diminishing. Moreover, these research activities have been aided by a number of journals, monograph series, museums, libraries, and university departments devoted exclusively or at least primarily to Oceania. The rich ethnographic data resulting from field research in Oceania have been drawn on heavily by many other social scientists for inspiration and for information respecting the range and variation of human social behavior.

The most influential innovation in social science research strategy and methodology to come out of Oceania was Malinowskis experience of long residence in a native community and active participation in its activities. He worked exclusively in the native vernacular, focused his attention upon the prosaic as well as the dramatic aspects of native life, and collected (and published) masses of documentary evidence to support and enrich his generalizations. It is somewhat ironic that Malinowskis style of field research has been more faithfully followed in Africa than in Oceania, with the outstanding exception of Raymond Firths work in Tikopia (Firth 1936; 1939; 1940).

Malinowski aimed at more or less total coverage of his native subjects way of life, and for some time after him this remained the objective of most social scientists working in the region. But this goal has increasingly given way to a narrower focus upon special aspects of native life, including economics, law, religion, ecology, acculturation, and education.

Malinowskis example of one-man field work has tended to prevail, although field research is coming to be conducted within the framework of larger-scale programs, such as the Coordinated Investigation of Micronesian Anthropology, the Tri-Institutional Pacific Program, the long-range New Guinea research program of the Australian National University, the University of Oregons study of resettled populations, the University of Washingtons study of cultural and physical evolution in New Guinea, the Harvard study of social change in the Society Islands, etc. In this connection, attention should be called to the research activities of such organizations as the South Pacific Commission (an international body designed to improve the welfare of Pacific islanders) and the French governments Office de la Recherche Scientifique et Technique Outre Mer, which though aimed primarily at the solution of practical problems have contributed useful data on some rapidly changing aspects of Oceanian ways of life.

Turning now to the substantive contributions to general social science theory that have come out of research in Oceaniacontributions in addition to the enrichment of the worlds ethnographic corpusone again begins with the writing of Malinowski, who audaciouslyalthough not always justifiablychallenged some of the basic assumptions of economics, comparative law, semantics, and psychoanalysis, and who in addition popularized the functional viewpoint already mentioned (Firth 1957). For Malinowski functionalism consisted mainly of a proposition to the effect that all of a societys customs are mutually interdependent and an analytical principle based on viewing institutions as instruments for satisfying basic human needs. The proposition has subsequently become an almost universally accepted canon among anthropologists, but not much use has been found for the analytical principle. Radcliffe-Browns contributions to general social science theory have been mainly in the field of comparative sociology(see Radcliffe-Brown 1922), and although his interests were somewhat narrower than Malinowskis he has left a comparably deep imprint. Perhaps the most successful implementations in Oceanian research of the general methods and theories of Malinowski and Radcliffe-Brown have been done, respectively, by Firth (1936) and Warner (1937).It now remains to list some other investigations in Oceania which, in my opinion, have served most to enrich social science either by proposing or testing theory or by describing novel or comparatively important institutions.

Major contributions to the sociology of kinship are to be found in the writings of Firth (1936),Warner (1937), Malinowski (1929), Radcliffebrown (1922), Elkin (1938), Mead (1934), R. M. Berndt and C. H. Berndt (1951), Meggitt (1962),and Goodenough (1951). Only from Africa have come works of comparable quality. Government and social control of relatively un-Westernized societies are usefully documented in the works of Malinowski (1926), Hogbin (1934), Guiart (1963),Oliver (1955), Pospisil (1958), and Berndt (1962).Useful studies of Oceanian economies are those by Malinowski (1922), Bell (1953), Salisbury(1962), and, especially, Firth (1939; 1959). The published works of Firth provide probably the fullest and most sophisticated treatment available on the economics of primitive societies.

Among the most useful studies of the social contexts of belief and ritual are those of Firth (1940), Fortune (1932; 1935), Malinowski (1935),Warner (1937), Guiart (1951), and Williams (1940). In this connection should be mentioned Batesons stimulating, and in some respects novel, multifaceted analysis of ritual behavior (1936), which deserves far wider attention than it has thus far received.

Many richly illustrated works have been published concerning the widely varied and extraordinarily elaborated graphic art tradition of Oceania, but only a few seek to relate these to social behavior, mainly those of Elkin et al. (1950),Mountford (1956), Firth (1936), and Guiart (1963b).

Drop Pollard for final ODI, urges legend Waqar

Tue, Oct 4, '16

SHARJAHLegendary Pakistan fast bowler, Waqar Younis, believes Kieron Pollard is hurting West Indies team morale with his lackadaisical approach and should be axed for tomorrows final One-Day International against Pakistan.

Speaking in his role as a television analyst following the second ODI on Sunday, Waqar said big-hitting all-rounder did not even try as the Caribbean side slid to a 59-run defeat in pursuit of an imposing 338 for victory at Sharjah Cricket Stadium.

Pollard entered in the 38th over with West Indies on 194 for four and facing a required run rate of nearly 12 an over but displayed little aggressive intent.

His approach and the way he played in this game and in any of the T20 games, youre destroying the morale of the team, said Waqar, the second highest wicket-taker in Pakistan Test history with 373 scalps from 87 games.

The way he battedhe went in with 11 and over or about 12 an over required and he is known for this sort of situation. And he just went in and he hit one boundary and batted the entire time and not going anywhere.

He wasnt there, he was not in the middle so I feel he needs a break. Whoever you want to bring in, Pollard needs a break. Thats how I feel.

SHARJAH, United Arab Emirates, (CMC) Former Pakistan speedster, Waqar Younis, believes the dramatic sacking of West In

dies Head Coach Phil Simmons on the eve of the ongoing tour, has had a negative impact on the Caribbean sides performance.

West Indies looked a shadow of themselves in the Twenty20 International series and were stunned 3-0 by Pakistan, and also suffered a heavy 111-run defeat in the opening One-Day International of the three-match series here last Friday.

And Waqar, who took 373 wickets in 87 Tests,said the uncharacteristically poor showing, especially in the T20s, was a sign that Simmons axing, and that of inspirational Captain Darren Sammy, had left the side in disarray.

Dwayne Bravo said on Saturday that the current players representing the West Indies against Pakistan is a lost group with many believing that windball cricket is better organised than what they are experiencing with the Caribbean team in Dubai.

I was there in Dubai and basically the players were lost, the management team was lost, everything just looked like we were school kids again, and the team meetings had no sort of positive inputs or anything like that. It was like we were just there, an obviously hurt Bravo stated.

Bravo said that while individually the West Indies players were always motivated, the events leading up to the team leaving the Caribbean disturbed the entire momentum of the squad.

The honest truth is that it is very difficult for a bunch of 15 guys to really switch on when they are leaving for a series and the day of the team travelling they find out that their head coach (Phil Simmons) was fired. Like which organisation in the world would do things like that? This was a coach that had the support of the entire team and one of the best coaches we have had and he has done so much in a short period. Everyone knows that, and we were making positives, stated Bravo.

SHARJAH: Fast-rising Babar Azam cracked a second successive hundred to guide Pakistan to a dominant 59-run win over the West Indies in the second one-day international in Sharjah, gaining an unbeatable 2-0 lead in three-match series.

Azam's brilliant 126-ball 123 formed the cornerstone of Pakistan's imposing 337-5 which also featured half-centuries from Shoaib Malik and Sarfraz Ahmed.

West Indies finished on 278-7 from their 50 overs with Darren Bravo hitting 61 and Marlon Samuels scoring 57.

The final match will be in Abu Dhabi on Wednesday.

It was a wonderful team effort, said Pakistan captain Azhar Ali.

We needed a good partnership after losing two early wickets and Azam and Malik gave that to us with pace and wisdom.West Indian captain Jason Holder rued his team's bad bowling.

SHARJAH: Babar Azam hit his maiden century while spinner Mohammad Nawaz grabbed four wickets as Pakistan thrashed the West Indies by 111 runs on the Duckworth-Lewis method in the first day-night international on Friday.

Azam's rapid-fire 139-ball 120 helped Pakistan post a challenging 284-9 in a match reduced to 49 overs a side due to a 70-minute floodlight failure at Sharjah Stadium in the UAE.

West Indies set 287 to win never got close and folded at 175 in 38.4 overs.

The victory gives Pakistan a 1-0 lead in the three-match series, building on their 3-0 whitewash in the Twenty20 series.

Like in the Twenty20 matches, the West Indian batsmen had little clue against Pakistan's spin bowling, with only Marlon Samuels (46) and Johnson Charles (20) offering any resistance.

Cloning/Embryonic Stem Cells – National Human Genome Research …

Posted: at 1:28 pm

Cloning/Embryonic Stem Cells

The term cloning is used by scientists to describe many different processes that involve making duplicates of biological material. In most cases, isolated genes or cells are duplicated for scientific study, and no new animal results. The experiment that led to the cloning of Dolly the sheep in 1997 was different: It used a cloning technique called somatic cell nuclear transfer and resulted in an animal that was a genetic twin -- although delayed in time -- of an adult sheep. This technique can also be used to produce an embryo from which cells called embryonic stem (ES) cells could be extracted to use in research into potential therapies for a wide variety of diseases.

Thus, in the past five years, much of the scientific and ethical debate about somatic cell nuclear transfer has focused on its two potential applications: 1) for reproductive purposes, i.e., to produce a child, or 2) for producing a source of ES cells for research.

The technique of transferring a nucleus from a somatic cell into an egg that produced Dolly was an extension of experiments that had been ongoing for over 40 years. In the simplest terms, the technique used to produce Dolly the sheep - somatic cell nuclear transplantation cloning - involves removing the nucleus of an egg and replacing it with the diploid nucleus of a somatic cell. Unlike sexual reproduction, during which a new organism is formed when the genetic material of the egg and sperm fuse, in nuclear transplantation cloning there is a single genetic "parent." This technique also differs from previous cloning techniques because it does not involve an existing embryo. Dolly is different because she is not genetically unique; when born she was genetically identical to an existing six-year-old ewe. Although the birth of Dolly was lauded as a success, in fact, the procedure has not been perfected and it is not yet clear whether Dolly will remain healthy or whether she is already experiencing subtle problems that might lead to serious diseases. Thus, the prospect of applying this technique in humans is troubling for scientific and safety reasons in addition to a variety of ethical reasons related to our ideas about the natural ordering of family and successive generations.

Several important concerns remain about the science and safety of nuclear transfer cloning using adult cells as the source of nuclei. To date, five mammalian species -- sheep, cattle, pigs, goats, and mice -- have been used extensively in reproductive cloning studies. Data from these experiments illustrate the problems involved. Typically, very few cloning attempts are successful. Many cloned animals die in utero, even at late stages or soon after birth, and those that survive frequently exhibit severe birth defects. In addition, female animals carrying cloned fetuses may face serious risks, including death from cloning-related complications.

An additional concern focuses on whether cellular aging will affect the ability of somatic cell nuclei to program normal development. As somatic cells divide they progressively age, and there is normally a defined number of cell divisions that can occur before senescence. Thus, the health effects for the resulting liveborn, having been created with an "aged" nucleus, are unknown. Recently it was reported that Dolly has arthritis, although it is not yet clear whether the five-and-a-half-year-old sheep is suffering from the condition as a result of the cloning process. And, scientists in Tokyo have shown that cloned mice die significantly earlier than those that are naturally conceived, raising an additional concern that the mutations that accumulate in somatic cells might affect nuclear transfer efficiency and lead to cancer and other diseases in offspring. Researchers working with clones of a Holstein cow say genetic programming errors may explain why so many cloned animals die, either as fetuses or newborns.

The announcement of Dolly sparked widespread speculation about a human child being created using somatic cell nuclear transfer. Much of the perceived fear that greeted this announcement centered on the misperception that a child or many children could be produced who would be identical to an already existing person. This fear is based on the idea of "genetic determinism" -- that genes alone determine all aspects of an individual -- and reflects the belief that a person's genes bear a simple relationship to the physical and psychological traits that compose that individual. Although genes play an essential role in the formation of physical and behavioral characteristics, each individual is, in fact, the result of a complex interaction between his or her genes and the environment within which he or she develops. Nonetheless, many of the concerns about cloning have focused on issues related to "playing God," interfering with the natural order of life, and somehow robbing a future individual of the right to a unique identity.

Several groups have concluded that reproductive cloning of human beings creates ethical and scientific risks that society should not tolerate. In 1997, the National Bioethics Advisory Commission recommended that it was morally unacceptable to attempt to create a child using somatic cell nuclear transfer cloning and suggested that a moratorium be imposed until safety of this technique could be assessed. The commission also cautioned against preempting the use of cloning technology for purposes unrelated to producing a liveborn child.

Similarly, in 2001 the National Academy of Sciences issued a report stating that the United States should ban human reproductive cloning aimed at creating a child because experience with reproductive cloning in animals suggests that the process would be dangerous for the woman, the fetus, and the newborn, and would likely fail. The report recommended that the proposed ban on human cloning should be reviewed within five years, but that it should be reconsidered "only if a new scientific review indicates that the procedures are likely to be safe and effective, and if a broad national dialogue on societal, religious and ethical issues suggests that reconsideration is warranted." The panel concluded that the scientific and medical considerations that justify a ban on human reproductive cloning at this time do not apply to nuclear transplantation to produce stem cells. Several other scientific and medical groups also have stated their opposition to the use of cloning for the purpose of producing a child.

The cloning debate was reopened with a new twist late in 1998, when two scientific reports were published regarding the successful isolation of human stem cells. Stem cells are unique and essential cells found in animals that are capable of continually reproducing themselves and renewing tissue throughout an individual organism's life. ES cells are the most versatile of all stem cells because they are less differentiated, or committed, to a particular function than adult stem cells. These cells have offered hope of new cures to debilitating and even fatal illness. Recent studies in mice and other animals have shown that ES cells can reduce symptoms of Parkinson's disease in mouse models, and work in other animal models and disease areas seems promising.

In the 1998 reports, ES cells were derived from in vitro embryos six to seven days old destined to be discarded by couples undergoing infertility treatments, and embryonic germ (EG) cells were obtained from cadaveric fetal tissue following elective abortion. A third report, appearing in the New York Times, claimed that a Massachusetts biotechnology company had fused a human cell with an enucleated cow egg, creating a hybrid clone that failed to progress beyond an early stage of development. This announcement served as a reminder that ES cells also could be derived from embryos created through somatic cell nuclear transfer, or cloning. In fact, several scientists believed that deriving ES cells in this manner is the most promising approach to developing treatments because the condition of in vitro fertilization (IVF) embryos stored over time is questionable and this type of cloning could overcome graft-host responses if resulting therapies were developed from the recipient's own DNA.

For those who believe that the embryo has the moral status of a person from the moment of conception, research or any other activity that would destroy it is wrong. For those who believe the human embryo deserves some measure of respect, but disagree that the respect due should equal that given to a fully formed human, it could be considered immoral not to use embryos that would otherwise be destroyed to develop potential cures for disease affecting millions of people. An additional concern related to public policy is whether federal funds should be used for research that some Americans find unethical.

Since 1996, Congress has prohibited researchers from using federal funds for human embryo research. In 1999, DHHS announced that it intended to fund research on human ES cells derived from embryos remaining after infertility treatments. This decision was based on an interpretation "that human embryonic stem cells are not a human embryo within the statutory definition" because "the cells do not have the capacity to develop into a human being even if transferred to the uterus, thus their destruction in the course of research would not constitute the destruction of an embryo." DHHS did not intend to fund research using stem cells derived from embryos created through cloning, although such efforts would be legal in the private sector.

In July 2001, the House of Representatives voted 265 to 162 to make any human cloning a criminal offense, including cloning to create an embryo for derivation of stem cells rather than to produce a child. In August 2002, President Bush, contending with a DHHS decision made during the Clinton administration, stated in a prime-time television address that federal support would be provided for research using a limited number of stem cell colonies already in existence (derived from leftover IVF embryos). Current bills before Congress would ban all forms of cloning outright, prohibit cloning for reproductive purposes, and impose a moratorium on cloning to derive stem cells for research, or prohibit cloning for reproductive purposes while allowing cloning for therapeutic purposes to go forward. As of late June, the Senate has taken no action. President Bush's Bioethics Council is expected to recommend the prohibition of reproductive cloning and a moratorium on therapeutic cloning later this summer.

Pros and Cons of Cloning – Buzzle

Posted: at 1:28 pm

Cloning is the process of creating a copy of a biological entity. In genetics, it refers to the process of making an identical copy of the DNA of an organism. Are you interested in understanding the pros and cons of cloning?

Advertisement

When Dolly, the first cloned sheep came in the news, cloning interested the masses. Not only researchers but even common people became interested in knowing about how cloning is done and what pros and cons it has. Everyone became more curious about how cloning could benefit the common man. Most of us want to know the pros and cons of cloning, its advantages and its potential risks to mankind. Let us understand them.

Cloning finds applications in genetic fingerprinting, amplification of DNA and alteration of the genetic makeup of organisms. It can be used to bring about desired changes in the genetic makeup of individuals thereby introducing positive traits in them, as also for the elimination of negative traits. Cloning can also be applied to plants to remove or alter defective genes, thereby making them resistant to diseases. Cloning may find applications in the development of human organs, thus making human life safer. Here we look at some of the potential advantages of cloning.

Organ Replacement

If vital organs of the human body can be cloned, they can serve as backups. Cloning body parts can serve as a lifesaver. When a body organ such as a kidney or heart fails to function, it may be possible to replace it with the cloned body organ.

Substitute for Natural Reproduction

Cloning in human beings can prove to be a solution to infertility. It can serve as an option for producing children. With cloning, it would be possible to produce certain desired traits in human beings. We might be able to produce children with certain qualities. Wouldn't that be close to creating a man-made being?!

Help in Genetic Research

Cloning technologies can prove helpful to researchers in genetics. They might be able to understand the composition of genes and the effects of genetic constituents on human traits, in a better manner. They will be able to alter genetic constituents in cloned human beings, thus simplifying their analysis of genes. Cloning may also help us combat a wide range of genetic diseases.

Obtain Specific Traits in Organisms

Cloning can make it possible for us to obtain customized organisms and harness them for the benefit of society. It can serve as the best means to replicate animals that can be used for research purposes. It can enable the genetic alteration of plants and animals. If positive changes can be brought about in living beings with the help of cloning, it will indeed be a boon to mankind.

Like every coin has two sides, cloning has its flip side too. Though cloning may work wonders in genetics, it has some potential disadvantages. Cloning, as you know, is copying or replicating biological traits in organisms. Thus it might reduce the diversity in nature. Imagine multiple living entities like one another! Another con of cloning is that it is not clear whether we will be able to bring all the potential uses of cloning into reality. Plus, there's a big question of whether the common man will afford harnessing cloning technologies to his benefit. Here we look at the potential disadvantages of cloning.

Detrimental to Genetic Diversity

Cloning creates identical genes. It is a process of replicating a genetic constitution, thus hampering the diversity in genes. In lessening genetic diversity, we weaken our ability of adaptation. Cloning is also detrimental to the beauty that lies in diversity.

Invitation to Malpractices

While cloning allows man to tamper with genes in human beings, it also makes deliberate reproduction of undesirable traits, a possibility. Cloning of body organs may invite malpractices in society.

Will it Reach the Common Man?

In cloning human organs and using them for transplant, or in cloning human beings themselves, technical and economic barriers will have to be considered. Will cloned organs be cost-effective? Will cloning techniques really reach the common man?

Man, a Man-made Being?

Moreover, cloning will put human and animal rights at stake. Will cloning fit into our ethical and moral principles? It will make man just another man-made being. Won't it devalue mankind? Won't it demean the value of human life?

Cloning is equal to emulating God. Is that easy? Is it risk-free? Many are afraid it is not.

Any technology that offers benefits will usually come with risks as well. In order to make wise decisions about using a technology, we must understand its potential impacts well enough to decide whether the risks are acceptably low.

What are the risks posed by the use of genetic engineering (GE) in agriculture? The answers fall mostly into two categories: risks to human health, and environmental impacts.

Photo: Roy Kaltschmidt, Lawrence Berkeley National Laboratories

Health risks of genetic engineering have sometimes been described in exaggerated, alarmist terms, implying that foods made from GE crops are inherently unsafe. There is no evidence, for instance, that refined products derived from GE crops, such as starch, sugar and oils, are different than those derived from conventionally bred crops.

It is also an exaggeration, however, to state that there are no health risks associated with GE. For one thing, not enough is known: research on the effects of specific genes has been limitedand tightly controlled by the industry.

But we do know of ways in which genetically engineered crops could cause health problems. For instance, genes from an allergenic plant could transfer this unwanted trait to the target plant. This phenomenon was documented in 1996, as soybeans with a Brazil nut geneadded to improve their value as animal feedproduced an allergic response in test subjects with Brazil nut allergies.

Unintended consequences like these underscore the need for effective regulation of GE products. In the absence of a rigorous approval process, there is nothing to ensure that GE crops that cause health problems will always be identified and kept off the market.

Genetically engineered crops can potentially cause environmental problems that result directly from the engineered traits. For instance, an engineered gene may cause a GE crop (or a wild relative of that crop) to become invasive or toxic to wildlife.

But the most damaging impact of GE in agriculture so far is the phenomenon of pesticide resistance. Millions of acres of U.S. farmland are now infested by weeds that have become resistant to the herbicide glyphosate. Overuse of Monsanto's "Roundup Ready" trait, which is engineered to tolerate the herbicide, has promoted the accelerated development of resistance in several weed species.

Looking for ways to fight back against these "superweeds," farmers are now turning to older, more toxic herbicides such as 2,4-D and dicamba. As if on cue, agribusiness companies have begun to develop new GE crops engineered to tolerate these older herbicideswith no guarantee that the Roundup Ready story will not repeat itself, producing a new wave of resistant weeds.

And this issue is not confined to herbicides: recent reports suggest a growing problem of corn rootworms resistant to the insecticide Bt, which some corn varieties have been engineered to produce.

As the superweed crisis illustrates, current applications of genetic engineering have become a key component of an unsustainable approach to food production: industrial agriculture, with its dependence on monoculturesupported by costly chemical inputsat the expense of the long-term health and productivity of the farm.

A different approach to farming is availablewhat UCS calls "healthy farms." This approach is not only more sustainable than industrial agriculture, but often more cost-effective. Yet as long as the marketplace of agricultural products and policies is dominated by the industrial model, prioritizing expensive products over knowledge-based agroecological approaches, healthy farm solutions face an uphill battle.

In the case of GE, better solutions include crop breeding (often assisted by molecular biology techniques) and agroecological practices such as crop rotation, cover crops, and integrated crop/livestock management.

Such healthy farm practices are the future of U.S. agricultureand policymakers can help speed the transition by supporting research and education on them. In the meantime, stronger regulation of the biotechnology industry is needed to minimize health and environmental risks from GE products.

Interspecies gene transfer occurs naturally; interspecies hybrids produced by sexual means can lead to new species with genetic components of both pre-existing species. Interspecies hybridization played an important role in the development of domesticated plants.

Interspecies gene transfer occurs naturally; interspecies hybrids produced by sexual means can lead to new species with genetic components of both pre-existing species. Interspecies hybridization played an important role in the development of domesticated plants. Interspecies hybrids can also be produced artificiallly between sexually incompatible species. Cells of both plants and animals can be caused to fuse, producing viable hybrid cell-lines. Cultured hybrid plant cells can regenerate whole plants, so cell fusion allows crosses of sexually incompatible species. Most animal cells cannot regenerate whole individuals; however, the fusion of antibody-forming cells (which are difficult to culture) and "transformed" (cancer-like) cells, gives rise to immortal cell-lines, each producing one particular antibody, so-called monoclonal antibodies. These cell-lines can be used for the commercial production of diagnostic and antidisease antibody preparations. (Fusions involving human cells play a major role in investigations of human heredity and GENETIC DISEASE.)

In nature, the transfer of genes between sexually incompatible species also occurs; for example, genes can be carried between species during viral infection. In its most limited sense, genetic engineering exploits the possibility of such transfers between remotely related species. There are two principle methods. First, genes from one organism can be implanted within another, so that the implanted genes function in the host organism. Alternatively, the new host organism (often a micro-organism) produces quantities of the DNA segment that contains a foreign gene, which can then be analysed and modified in the test tube, before return to the species from which the gene originated. Dr Michael SMITH of the University of British Columbia was the corecipient of the 1993 NOBEL PRIZE in Chemistry for his invention of one of the most direct means to modify gene structure in the test tube, a technique known as in vitro mutagenesis.

The continuing development of modern genetic engineering depends upon a number of major technical advances: cloning, gene cloning and DNA sequencing.

Cloning is the production of a group of genetically identical cells or individuals from a single starting cell; all members of a clone are effectively genetically identical. Most single-celled organisms, many plants and a few multicellular animals form clones as a means of reproduction - "asexual" reproduction. In humans, identical twins are clones, developing after the separation of the earliest cells formed from a single fertilized egg.

Cloning is not strictly genetic engineering, since the genome normally remains unaltered, but it is a practical means to propagate engineered organisms.

In combination with test-tube fertilization and embryo transplants, Alta Genetics of Calgary is a world leader in the use of artificial twinning as a tool in the genetic engineering of cattle. Manipulating plant hormones in plant cell cultures can yield clones consisting of millions of plantlets, which may be packageable to form artificial seed.

Cloning of genetically engineered animals is generally difficult. Clones of frogs have been produced by transplanting identical nuclei from a single embryo, each to a different nucleus-free egg. This technique is not applicable to mammals. However, clones of cells derived from very young mammalian embryos (embryonic stem cells) can be used to reconstitute whole animals and are widely used for genetic engineering of mice. There is no reported instance of cloning of humans by any artificial means. Nonetheless, frequent calls for regulation of human cloning and genetic engineering occur, which stem from the same considerations that lead most commentators to reject eugenics.

Gene cloning is fundamental to genetic engineering. A segment of DNA from any donor organism is joined in the test tube to a second DNA molecule, known as a vector, to form a "recombinant " DNA molecule.

The design of appropriate vectors is an important practical area. Entry of DNA into each kind of cell is best mediated by different vectors. For BACTERIA, vectors are based on DNA molecules that move between cells in nature - bacterial VIRUSES and plasmids. Mammalian vectors usually derive from mammalian viruses. In higher plants, the favoured system is the infectious agent of crown-gall tumours.

Gene cloning in microbes has reached commercial application, notably with the marketing of human INSULIN produced by bacteria. Many similar products are now available, including growth hormones, blood-clotting factors and antiviral interferons. Gene cloning has revolutionized the understanding of genes, cells and diseases particularly of CANCER. It has raised the diagnosis of hereditary disease to high science, has contributed precise diagnostic tools for infectious disease and is fundamental to the use of DNA testing in forensic science.

The ability to clone genes led directly to the discovery of the means to analyse the precise chemical structure of DNA; that is, DNA sequencing. A worldwide co-operative project, the Human Genome Project, is now underway, with the object of cloning and sequencing the totality of human DNA, which contains perhaps 100000 or more genes. To date, at least 80% of the DNA has been cloned and localized roughly within the human chromosome set. It is predicted that the sequencing will be effectively completed in less than 20 years. However, it is clear that the biological meaning of the DNA structure will take decades, if not centuries, to decipher.

To avoid potential hazards deriving from genetic engineering, gene cloning even in bacteria is publicly regulated in Canada and the US by the scientific granting agencies and in some other countries by law. Biological containment, the deliberate hereditary debilitation of host cells and vectors, is required. In using mammals and higher plants, especially strict regulations apply, requiring physical isolation.

A great deal of work remains, both in the development of techniques and in the acquisition of fundamental knowledge needed to apply the techniques appropriately. Nonetheless, genetic engineering promises a world of tailor-made CROP plants and farm animals; cures for hereditary disease by gene replacement therapy; an analytical understanding of cancer and its treatment; and a world in which much of our present-day harsh chemical technology is replaced by milder, organism-dependent, fermentation processing.

In Canada, genetic engineering research is taking place in the laboratories of universities, industries, and federal and provincial research organizations. In the industrial sector, medical applications are being developed, for example at Ayerst Laboratories, Montral, AVENTIS PASTEUR LTD., Toronto, and theINSTITUT ARMAND-FRAPPIER, Laval-des-Rapides, Qubec.

Inco is researching applications for MINING and METALLURGY, and LABATT'S BREWERIESis applying recombinant DNA techniques to brewing technologies. A large number of Canadian companies engage in the research and development of genetically engineered products, particularly in the area of PHARMACEUTICALS and medical diagnostics. As many as half of the federally operated NATIONAL RESEARCH COUNCIL Research Institutes have significant involvement with genetic engineering, including the Biotechnology Research Institute (Montral) and the Plant Biotechnology Institute (Saskatoon), whose mandates are largely in this area. The Veterinary Infectious Disease Organization, based at University of Saskatchewan, is using genetic engineering technology for production of new vaccines for livestock diseases.

Pros and Cons of Genetic Engineering | HRFnd

Posted: at 1:21 pm

Manipulation of genes in natural organisms, such as plants, animals, and even humans, is considered genetic engineering. This is done using a variety of different techniques like molecular cloning. These processes can cause dramatic changes in the natural makeup and characteristic of the organism. There are benefits and risks associated with genetic engineering, just like most other scientific practices.

Genetic engineering offers benefits such as:

1. Better Flavor, Growth Rate and Nutrition Crops like potatoes, soybeans and tomatoes are now sometimes genetically engineered in order to improve size, crop yield, and nutritional values of the plants. These genetically engineered crops also possess the ability to grow in lands that would normally not be suitable for cultivation.

2. Pest-resistant Crops and Extended Shelf Life Engineered seeds can resist pests and having a better chance at survival in harsh weather. Biotechnology could be in increasing the shelf life of many foods.

3. Genetic Alteration to Supply New Foods Genetic engineering can also be used in producing completely new substances like proteins or other nutrients in food. This may up the benefits they have for medical uses.

4. Modification of the Human DNA Genes that are responsible for unique and desirable qualities in the human DNA can be exposed and introduced into the genes of another person. This changes the structural elements of a persons DNA. The effects of this are not know.

The following are the issues that genetic engineering can trigger:

1. May Hamper Nutritional Value Genetic engineering on food also includes the infectivity of genes in root crops. These crops might supersede the natural weeds. These can be dangerous for the natural plants. Unpleasant genetic mutations could result to an increased allergy occurrence of the crop. Some people believe that this science on foods can hamper the nutrients contained by the crops although their appearance and taste were enhanced.

2. May Introduce Risky Pathogens Horizontal gene shift could give increase to other pathogens. While it increases the immunity against diseases among the plants, the resistant genes can be transmitted to harmful pathogens.

3. May Result to Genetic Problems Gene therapy on humans can end to some side effects. While relieving one problem, the treatment may cause the onset of another issue. As a single cell is liable for various characteristics, the cell isolation process will be responsible for one trait will be complicated.

4. Unfavorable to Genetic Diversity Genetic engineering can affect the diversity among the individuals. Cloning might be unfavorable to individualism. Furthermore, such process might not be affordable for poor. Hence, it makes the gene therapy impossible for an average person.

Genetic engineering might work excellently but after all, it is a kind of process that manipulates the natural. This is altering something which has not been created originally by humans. What can you say about this?

Ron Paul suggests support for Jill Stein, admits he is …

Posted: at 1:19 pm

Former Texas congressman Ron Paul, a longtime hero of the libertarian right, surprised many on Monday when he told MSNBC that he has no plans to back Libertarian Party presidential nominee Gary Johnson.

Paul, who himself was the Libertarian nominee in 1988 and ran as a Republican primary candidate on several subsequent occasions, said he actually prefers Green Party nominee Jill Stein on important issues like civil liberties and foreign policy.

Shes probably the best on foreign policy at the moment, Paul said, stressing that he hasnt endorsed anyone for president yet.

On Gary Johnson, Paul explained, he does not come across with a crisp libertarian message.

Johnson has come under recent ridicule for his inability to express a coherent answer on the conflict in Syria, his so-called Aleppo moment, and then for his inability to name a single foreign leader he admired.

If you want to express yourself I am voting for the non-aggressive principles that create the libertarian message. And that is, nobody can commit aggression. Individuals cannot, nor the government. Unfortunately, theres not a crisp answer, Paul said, referring to Johnson.

Paul continued: On occasion, Gary will say something good about the economy. Even Donald Trump I find him talking about the bubble that the Federal Reserve created. All those things, if you put them together, you come up with a libertarian message.

Watch below:

Paul earlier told Fox Business that he is disappointed with the performance of the Libertarian leaders.

Pauls son, Sen. Rand Paul, R-Ky., a failed 2016 GOP presidential candidate, has endorsed Republican nominee Donald Trump.
