Legal Strategies For A Strong Defense Against Bribery Accusations – American Judicature Society

Posted: September 25, 2023 at 7:38 pm

Accusations of bribery can have severe consequences for individuals and organizations alike. From criminal charges to hefty fines, such allegations can tarnish reputations and lead to prolonged legal battles. To defend against bribery accusations effectively, it is crucial to understand lawyers tactics. This article will explore a few strategies that attorneys can use when navigating bribery allegations.

If you are accused of bribery, one of the first steps in mounting a defense against accusations of bribery involves gaining a comprehensive understanding of the relevant laws and regulations. The lawyer representing the accused must possess in-depth knowledge of state bribery statutes, and all pertinent attorneys can start constructing a defense by analyzing precedents and grasping the elements required during a defense.

Once hired by an accused party, lawyers will investigate bribery allegations. These investigations may involve scrutinizing documents, interviewing witnesses, and gathering evidence supporting their clients innocence or highlighting weaknesses in the prosecutions case. By carrying out this investigation, attorneys are better equipped to build a strong defense.

Defending against bribery allegations involves questioning and examining the evidence presented by prosecutors. Attorneys will meticulously analyze all types of evidence, such as witness statements, financial records, and any other documents provided by opposing counsel or government agencies involved in the case. They will search for inconsistencies or weaknesses that may undermine credibility or raise doubts about guilt.

Another strategy when dealing with accusations of bribery is to prepare witnesses who may testify on behalf of the accused party. Lawyers work closely with these witnesses to ensure they are ready for questioning during depositions and trial testimony. This preparation may include practicing techniques for examination while also anticipating cross-examination approaches used by prosecutors.

When defending against bribery allegations, it is crucial for attorneys to understand the industry or sector in which the accused party operates. Lawyers can employ effective strategies during legal proceedings by acquiring industry knowledge and expertise. This might involve seeking advice from witnesses who can provide testimony on issues related to the bribery allegations.

In certain circumstances, negotiating a plea agreement with prosecutors may be the strategic course of action when faced with accusations of bribery. Experienced defense lawyers carefully assess the strength of the evidence against their clients and evaluate sentencing outcomes to provide informed advice on whether pursuing a plea agreement is in their clients best interest. Defense attorneys work diligently to secure terms that minimize penalties if negotiations are pursued.

If prosecutors obtain evidence through a search or seizure, skilled defense lawyers will raise objections based on Fourth Amendment protections. By analyzing search warrants and other relevant documents, attorneys can identify any violations law enforcement officials commit. Successfully challenging this evidence can have a huge impact on the prosecutions case.

In proceedings involving bribery allegations, defense attorneys must maintain documentation of all interactions with opposing counsel, government agencies, witnesses, and clients themselves. These meticulous notes ensure the recording of discussions and safeguard against errors or misinterpretations that could affect strategies or jeopardize clients interests.

Bribery accusations often carry consequences for individuals or organizations involved. Skilled defense attorneys recognize the importance of incorporating public relations strategies into their defense plans. By working with the public relations teams of their clients, lawyers can effectively manage media coverage and safeguard their clients rights within the framework of established ethical standards.

To effectively counter bribery allegations, it is crucial to understand the law, conduct investigations, analyze evidence meticulously, prepare witnesses to demonstrate expertise in relevant industries or sectors, negotiate adequately, skillfully challenge unlawfully obtained evidence, maintain meticulous documentation practices, and collaborate with public relations teams. By employing these strategies, in conjunction with defense tactics tailored to the circumstances of each case, accused parties enhance their chances of mounting a successful defense against bribery accusations. These legal strategies play a key role in ensuring treatment and protecting the legal rights of both individuals and organizations.

As psychedelic-assisted therapy grows, so does interest from a new group: chaplains – NPR

Research on the therapeutic use of psychedelics is underway at several universities, and data continues to accumulate on how they may help with conditions from PTSD to depression. Many states and localities across the country are considering legislation. Some, like Oregon and Colorado, have already passed regulatory models, which involve licensing facilitators to administer these drugs. And there's increasing interest in that work from a group of professionals who already guide people through life's deep and difficult times: chaplains.

Chaplains are religious professionals who work in non-religious settings hospitals, schools, battlefields. Although they're trained and often ordained in a particular tradition, they help people of any faith or none at all wrestle with spiritual issues, and connect with a sense of meaning.

"We are with people in deep moments of grief, deep moments of pain, deep moments of life transition," explains Caroline Peacock, an Episcopal priest who serves as director of spiritual health at Emory University's Winship Cancer Institute. "And we know how to be with people in these very, very hard moments."

Peacock recently drew upon this training as part of a clinical trial using psilocybin, the compound in so-called "magic mushrooms," at Emory University's Winship Cancer Institute. Their results will be published next year. In the study, chaplains worked alongside mental health practitioners to administer the psychedelic drug to terminal cancer patients. And after the treatment, they provided what's called integration using their experience navigating shifts in worldview to help patients make sense of the experience.

After participating in the trial, Peacock convened a Psychedelic Care Network within the Chaplaincy think tank group Transforming Chaplaincy, which over 150 fellow chaplains have joined. The conversation is growing within the field both the Association of Professional Chaplains and the Neshama: Association of Jewish Chaplains held workshops on psychedelic-assisted therapy at their most recent annual conferences, and panels and webinars have been held in many forums, as chaplains explore this topic.

And while some chaplains are exploring psychedelic-assisted therapy because of their deep well of experience providing a non-judgmental presence to help make sense of life's difficult moments, many are also drawn to it because people taking these drugs often report what's described as a mystical experience.

Anthony Bossis is a clinical psychologist at NYU Grossman School of Medicine, who has spent 15 years conducting psilocybin trials with patients facing advanced cancer. And he says patients taking the medication report a sense of awe and wonder, of interconnection, of transcendence. Moreover, he says, the research shows that the spiritual dimension of psychedelic treatment seems to be part of what makes the therapy therapeutic.

"The findings have shown already that the mystical experience has been a predictor, or a mediator, in terms of better outcomes," explains Bossis. "And we are seeing rapid and sustained reductions in depression, anxiety, hopelessness, fear of death, in people who do have an advanced illness who have this experience."

Given how frequently people report these spiritual encounters on psychedelics, it's not surprising that some religious practices have been built around them. Ayahuasca ceremonies in South America, peyote rituals in Mexico and the Southwest. But more and more, religions that don't have these traditions are saying they do have a container for these experiences.

Jaime Clark-Soles is a New Testament scholar, and directs the Baptist House of Studies at Southern Methodist University. She says that from Genesis to Revelation, scripture shows examples of faithful believers experiencing extraordinary states of consciousness, using fasting, prayer, and retreats, to change their everyday world, and step into a different sort of reality.

"To go to that place where you can stand in the presence of God. You know, 'be still and know that I am God,'" quotes Clark-Soles.

Clark-Soles took part in a clinical trial giving psilocybin to religious professionals at Johns Hopkins University, and says she experienced the presence of God fully and profoundly. Now, she's enrolled in a facilitator training program for psychedelic-assisted therapy, and hopes to bring awareness of the practice to others in the faith community.

She's heard pushback from some in that community, saying that the spiritual dimension of these drugs is just drugs... not God. But she says the moment when she accepted Jesus Christ, which nobody in her tradition would question, was also shaped by a context that affected her perceptions.

"I was away, I was in a retreat setting," says Clark-Soles. "I went outside, I was in nature, had a direct encounter with God. And here I am a seminary professor teaching, teaching Bible, right?"

Science can't tell us if any religious experience is real. The metrics we have are what people report on what they feel, and how their lives have been changed. As Clark-Soles says, "what fruits are born of it."

And people's lives have been changed by psychedelics, often in profound ways. Dr. Anthony Bossis has seen it throughout his research.

"For a person to have the experience, or the insight, that 'I'm not just my body, I'm not just my cancer' that's been a gift for people at the end of life," says Bossis. "To identify not only with a failing body, which will soon stop working, but that possibly there's something more remarkable at work in who we are as humans."

Religion has long offered a context, a language, for engaging with things in this world that are beyond everyday comprehension. Things we can't see the beginning or end of. How to live, and forgive, and make meaning. And with psychedelics, chaplains are hoping to bring their experience with these old questions into a new conversation to help those facing the end of life, or those just trying to figure out how to live it.

California Governor Says Psychedelics Have ‘Profound’ Healing Potential, But He’s Undecided On Legalization Bill As … – Marijuana Moment

Posted: at 7:36 pm

Californias governor says that while he understands the profound potential of psychedelics to treat certain mental health conditions, hes still undecided on how he will approach a bill to legalize small amounts of certain entheogenic substances thats on his deskeven as new polling shows a majority of likely voters in the state back the reform.

Gov. Gavin Newsoms (D) position on psychedelics has been murky, with no clear indication of whether hed sign the legislation from Sen. Scott Wiener (D). But in a recent interview with Politico, he shared mixed feelings about the proposal.

On the one hand, he said as the father of four young children, he views issues through a different prism than he did when he led the charge on legalizing marijuana and pushed for other drug policy reforms, including supporting certain harm reduction services like syringe exchange programs.

Im also mindful of the anxiety and stress thats out there as well, he said. And thats a new spectrum of some respects.

On the other hand, the governor said hes also deeply mindful of the potential benefits of psychedelics.

I have a lot of friends that are vets, so he understands the profound and consequential nature of how these drugs have been used to address PTSD.

That is what I will bring in to a review of this bill, he said.

Watch Newsom discuss the psychedelics reform legislation, starting at 21:00 intothe video below:

Likely voters in California are more decided on the issue of psychedelics, according to an FM3 poll that was conducted last month. The survey, first reported by The San Francisco Chronicle, found that 60 percent of California likely voters support the psychedelics bill that the legislature approved, including 30 percent who strongly support it.

Another 44 percent of respondents said theyd view their state lawmakers more favorably if they supported psychedelics reform legislation, while 19 percent said it wouldnt make a difference and 38 percent said theyd view them less favorably.

In conclusion, California voters broadly support reforming laws around personal possession of plant-based psychedelics which can be effective in treating PTSD, anxiety and depression, the firm wrote. Support for such a bill is a net- positive for a state legislator as well.

Patreon supporters pledging at least $25/month get access to our interactive maps, charts and hearing calendar so they dont miss any developments.

But for Newsom, it may not just be Californians hes thinking about as he weighs what to do with the psychedelics bill. Its widely speculated that the governor, who is termed out in 2026, is considering a future run for president, and he may worry about possible fallout in other battleground states if hes linked to legalizing other drugs.

Newsom has already shown a willingness to flout drug policy reform advocates. Last session, for example, he vetoed a bill to establish a safe drug consumption site pilot program in the state that was also sponsored by Wiener.

This session, meanwhile, the governor wont just be deciding on the psychedelics legislation. He has until October 14 to act on more than a dozen marijuana and other drug policy-related bills. That includes measures toprevent employers from asking job applicants about marijuana use,legalize cannabis cafes and promote environmentally sustainable track-and-trace plant tagging.

This Maine City Moves Unanimously On Decriminalizing Psychedelics: Focus On Public Health – Benzinga

Posted: at 7:36 pm

In a groundbreaking move, Portland, Maineunanimously advances a resolution aimed at decriminalizing select psychedelic plants and fungi.

Backed by Decriminalize Maine, this move has the potential to reshape drug policies within the city, according toMarijuana Moment.

See Also: PsychMD's Nationwide, Safe-Supplied AI-Driven Ketamine Therapy With US Vets In Mind

The resolution targets specific natural substances, including psilocybin, psilocin, ibogaine, mescaline (excluding peyote), and dimethyltryptamine (DMT). Notably, peyote is excluded from the list due to its ecological vulnerability and profound cultural significance to Indigenous communities.

What sets this resolution apart is its focus on promoting personal use and sharing without compensation, particularly through home cultivation. However, it's essential to understand that criminal enforcement will not waver for activities such as selling, dispensing, possessing on school premises, or driving under the influence of these substances.

One of the most pivotal aspects of this resolution is the city's commitment to reprioritizing its resources. It emphasizes that city funds and resources should not be utilized to aid in the investigation or criminal prosecution of individuals engaged in the covered activities.

Councilor Anna Trevorrow plays a key role in introducing amendments to the resolution, with a focus on encouraging safer substance use practices. By allowing sharing and home cultivation, the city aims to deter involvement in the black market and align with communal and cultural usage patterns.

Inspired by a similar measure in Cambridge, Massachusetts, the Portland resolution is driven by a commitment to medical and wellness perspectives. Councilor April Fournier underscored the natural use of these plants in supporting individuals on their healing journeys.

Whats Next?It's worth noting that the resolution will undergo thorough federal funding checks before a full City Council vote. The first reading is scheduled for October 2, with potential council action on October 16, pending any unforeseen delays.

Tech Leaders Are Finding Balance Through Microdosing Psychedelics – The Dales Report

Posted: at 7:36 pm

Psychedelicsare one of the buzziest topics intech these days. With entrepreneursvouching for their benefitsfor creativity, focus and general well-being as well asresearch institutions and companies seekingFDA approval for medical treatments, these compounds are entering themainstream.

Microdosing: Whats It All About?

Pretty much what the word sounds like,microdosing involvestakingaroundone-tenth the amountof a normaldose of a psychedelic.

Testimonies from regulars to microdosinginclude enhanced management of symptoms of PTSD, anxiety, depression, ADHDand even chronic pain. Others microdose tooptimizetheir quality of life.

Although scientific evidence on microdosings benefits is somewhat hard to gather, the practice is believed to date back tothe 1500s. Modern Western practices began in the1960sand continued undergroundafter psychedelics were banned in the 60s and 70s,The Washington Postreports.

While she incorporates different modalities into her coaching, Mugglebee highlights the unique role of microdosing psychedelics -noticeably psilocybin and LSD to help people transition away from pharmaceuticals, and pay close attention to themselves.

This is a key issue, as most top executives in the field are addicted to intensity, which typically leads to unreflectiveness and showing a lack of careful thought. Theyre addicted to working. Theyre addicted to making money. Theyre addicted to being right. Theyre addicted to being on autopilot so that they can get done what they need to get done, Mugglebee explains.

Microdosing psychedelics, she notes,wont resolve all problems. The process involves noticing what is going on around one without judgment. It is alsodependent on where each person is in their journey of building their self-awareness of building their ability to be present, to be in their body and to be in deep inquiry.

Chronic Pain Can Be Treated by Psychedelics, Survey Suggests – Psychedelic Spotlight

Posted: at 7:36 pm

More research is emerging that suggests chronic pain may soon be added to the long list of medical conditions psychedelics can relieve.

A new study published in the European Journal of Pain last month found that both macro and micro doses of classic psychedelics LSD, psilocybin, DMT, mescaline led to better pain relief compared to conventional medication in volunteers surveyed.

Participants reported that full doses seem to achieve better perceived results in pain relief than microdosing, while microdosing's effectiveness seems comparable to that of conventional medication according to survey participants, the paper concluded.

Researchers focused on five conditions: fibromyalgia, arthritis, migraine, tension-type headache and sciatica.

Four of those five, with sciatica being the exception, were reported to be relieved by psychedelics on the dosage day, as well as 1-3 days after, with a few even reporting pain relief beyond the third day.

Psilocybin and LSD were the most common drugs used in this survey of 170 participants.

The effect of psychedelics on pain related to sciatica was statistically non-significant, researchers wrote. This result may indicate that these substances hold promise only for certain kinds of pain conditions, presumably those in which the inflammatory and/or psychosomatic components play a more prominent role.

Though data obtained from this survey is promising, echoing previous results from researchers investigating psychedelics' effect on chronic pain an issue impacting 20 percent of the world's population study authors acknowledge a number of limitations, with the biggest being design.

It provides purely retrospective self-ratings from a self-selected sample of individuals who self-administer psychedelics, the paper notes. This design carries the risk of obtaining biased data and the generalizability of the produced results is only limited. It provides limited information to disentangle the role that different mechanisms play to achieve these perceived analgesic effects.

Authors acknowledged controlled studies are needed, and recommend researchers design clinical trials to explore further.

Amanda Feilding, founder and director of the Beckley Foundation, initiated the survey after establishing The Beckley/Maastricht Microdosing Research Programme, which is dedicated to studying the effects of microdosing LSD on mood, cognitive functions, and pain management in humans.

The program's previous placebo-controlled clinical study of 24 healthy volunteers found that a 20 microgram dose of LSD significantly reduced pain perception, as compared to the placebo, during cold pressure tests. I am encouraged by these results as I have long believed that LSD may not only change the sensations of pain but also our subjective relationship with it, she said after that study was published in 2020. We must continue to explore this with the aim of providing safer, non-addictive alternatives to pain management.

As Psychedelic Spotlight previously reported, MindMed is also exploring LSD for chronic pain treatment, while Imperial College London researchers found in 2021 that nine out of 11 chronic pain sufferers self-medicating with psychedelics reported complete, or at least partial, analgesia during their dosage experience.

More recently, a 9/11 first responder advocating for California lawmakers to decriminalize psychedelics, shared that psilocybin healed his PTSD as well as debilitating cluster headaches. I stopped taking the cocktail of pills I had been prescribed, many of which caused damaging side effects and were addictive, he wrote, adding: Its not an exaggeration to say that psilocybin gave me my life back. Its been transformative, and allowed me to feel happiness and joy in a way I never thought I would again.

Leader of IBM’s Quantum Safe Team to speak at URI – University of Rhode Island

Posted: September 23, 2023 at 10:00 am

KINGSTON, R.I. Sept. 21, 2023 As part of its quantum computing initiative, the University of Rhode Island will welcome Charles Robinson, worldwide lead of IBMs Quantum Safe Team, to campus for a public lecture. Robinson will give a talk titled From North Philly to Quantum Computing: Lessons Learned Along the Way on Monday, Sept. 25, at 4 p.m. in Edwards Hall.

The path from North Philly to being IBMs worldwide leader of the Quantum Safe Team has not been a straight line, Robinson said. In my presentation, I want to highlight the types of obstacles that I overcame and that many of you will likely experience. More important are the strategies and attitudes that you can employ to overcome hurdles, survive, and excel. No one size fits all but, at the end of the day, there is always a path forward.

As leader of IBMs Quantum Safe Team, Robinson works to develop and implement technologies that will protect data in a post-quantum world. Quantum computerscomputer systems that harness the behavior of matter at the tiniest scalesare expected to be able to perform calculations in seconds that would take years on even the most powerful computers operating today. While that dramatic increase in computing power promises to be an enormous boon for science and industry, it comes with a problem: Most of the encryption schemes currently used to secure data will be rendered obsolete as soon as large-scale quantum systems come online.

The Quantum Safe Team develops new encryption algorithms that will remain robust in the face of quantum computing power. The team also works with governments and companies all over the world to help them prepare for the coming quantum revolution. Doing so is critical to protecting credit card numbers, bank account information, medical records, and all other sensitive information that can be accessed via the internet.

Len Kahn, chair of the URI Department of Physics, says that quantum security represents an immediate area of focus in the coming quantum computing revolution.

All of the data thats on the internet now needs to be secured before quantum computers come online, Kahn said. We need to think about training people now to work on this and other critical problems, which is part of what were hoping to do with the quantum computing initiative at URI.

Kahn says that having Robinson speak at URI is important in part because of his unconventional path to worldwide leadership in the quantum field, as well as his efforts to make sure quantum information science is a career path available to anyone.

Robinson trained as a corpsman in the Navy before transitioning to engineering in community college. He went on to graduate from Howard University and receiving a graduate degree from Johns Hopkins. After working as an engineer and software developer for several large firms, Robinson began working extensively with the defense and intelligence community on issues related to communications and computing. He became the worldwide leader of the Quantum Safe Team in 2020.

Robinson has also worked extensively with Howard Universitys IBM-HBCU QuantumCenter, which aims to prepare and developtalent from historically Black colleges and universities for the quantum future.

The quantum revolution represents both tremendous challenges and opportunities, Kahn said. If were going to meet these challenges and create the workforce of tomorrow, well need to engage communities that have been traditionally underrepresented in scientific fields. Charles is a knowledgeable resource, and we continue to benefit from his experience.

The event is sponsored by the Office of the Provost, the Academic Enhancement Center, and the Department of Physics.

Zentropy A New Theory That Could Transform Material Science – SciTechDaily

Posted: at 10:00 am

The universe naturally gravitates towards disorder, and only through the input of energy can we combat this inevitable chaos. This idea is encapsulated in the concept of entropy, evident in everyday phenomena like ice melting, fires burning, and water boiling. However, zentropy theory introduces an additional layer to this understanding.

This theory was developed by a team led by Zi-Kui Liu, the distinguished Dorothy Pate Enright Professor of Materials Science and Engineering at Penn State. The Z in zentropy is derived from the German term Zustandssumm, which translates to the sum over states of entropy.

Alternatively, Liu said, zentropy may be considered as a play on the term zen from Buddhism and entropy to gain insight on the nature of a system. The idea, Liu said, is to consider how entropy can occur over multiple scales within a system to help predict potential outcomes of the system when influenced by its surroundings.

Liu and his research team have published their latest paper on the concept, providing evidence that the approach may offer a way to predict the outcome of experiments and enable more efficient discovery and design of new ferroelectric materials. The work, which incorporates some intuition and a lot of physics to provide a parameter-free pathway to predicting how advanced materials behave, was published inScripta Materialia.

Ferroelectrics have unique properties, making them valuable for a variety of applications both now and in developing materials, researchers said. One such property is spontaneous electric polarization that can be reversed by applying an electric field, which facilitates technologies ranging from ultrasounds to ink-jet printers to energy-efficient RAM for computers to the ferroelectric-driven gyroscope in smartphones that enable smooth videos and sharp photos.

To develop these technologies, researchers need to experiment to understand the behavior of such polarization and its reversal. For efficiencys sake, the researchers usually design their experiments based on predicted outcomes. Typically, such predictions require adjustments called fitting parameters to closely match real-world variables, which take time and energy to determine. But zentropy can integrate top-down statistical and bottom-up quantum mechanics to predict experimental measures of the system without such adjustments.

Of course, at the end of the day, the experiments are the ultimate test, but we found that zentropy can provide a quantitative prediction that can narrow down the possibilities significantly, Liu said. You can design better experiments to explore ferroelectric material and the research work can move much faster, and this means you save time, energy, and money and are more efficient.

While Liu and his team have successfully applied zentropy theory to predict the magnetic properties of a range of materials for various phenomena, discovering how to apply it to ferroelectric materials has been tricky. In the current study, the researchers reported finding a method to apply zentropy theory to ferroelectrics, focusing on lead titanate. Like all ferroelectrics, lead titanate possesses electric polarization that can be reversed when external electric fields, temperature changes, or mechanical stress is applied.

As an electric field reverses electric polarization reverses, the system transitions from ordered in one direction to disordered and then to ordered again as the system settles into the new direction. However, this ferroelectricity occurs only below a critical temperature unique to each ferroelectric material. Above this temperature, ferroelectricity the ability to reverse polarization disappears and paraelectricity the ability to become polarized emerges. The change is called the phase transition. The measurement of those temperatures can indicate critical information about the outcome of various experiments, Liu said. However, predicting the phase transition prior to an experiment is nearly impossible.

No theory and method can accurately predict the free energy of the ferroelectric materials and the phase transitions prior to the experiments, Liu said. The best prediction of transition temperature is more than 100 degrees away from the experiments actual temperature.

This discrepancy arises due to the unknown uncertainties in models, as well as fitting parameters that could not consider all salient information affecting the actual measurements. For example, an often-used theory characterizes macroscopic features of ferroelectricity and paraelectricity but does not consider microscopic features such as dynamic domain walls boundaries between regions with distinct polarization characteristics within the material. These configurations are building blocks of the system and fluctuate significantly with respect to temperature and electric field.

In ferroelectrics, the configuration of electric dipoles in the material can change the direction of polarization. The researchers applied zentropy to predict the phase transitions in lead titanate, including identifying three types of possible configurations in the material.

The predictions made by the researchers were effective and in agreement with observations made during experiments reported in the scientific literature, according to Liu. They used publicly available data on domain wall energies to predict a transition temperature of 776 degrees Kelvin, showing a remarkable agreement withthe observed experimental transition temperature of 763 degrees Kelvin. Liu said the team is working on further reducing the difference between predicted and observed temperatures with better predictions of domain wall energies as a function of temperature.

This ability to predict transition temperature so closely to the actual measurements can provide valuable insights into the physics of ferroelectric material and help scientists to better their experimental designs, Liu said.

This basically means you can have some intuitions and a predictive approach on how a material behaves both microscopically and macroscopically before you conduct the experiments, Liu said. We can start predicting the outcome accurately before the experiment.

Along with Liu, other researchers in the study from Penn State include Shun-Li Shang, research professor of materials science and engineering; Yi Wang, research professor of materials science and engineering; and Jinglian Du, research fellow in materials science and engineering at the time of the study.
