In the United States, screening the urine of employees or job applicants for the presence of drugs has become commonplace. A survey of 794 large- and mediumsized companies, conducted by the American Management Association in January 1994, found that 87 percent of them now test job applicants for drug use. In 1987, a similar survey found that 22 percent screened job applicants. Federally mandated drug testing programs with random testing requirements affect millions of workers in the transportation industry, the nuclear (...) power industry, and the United States civil and military services.As some of these programs pass their fifth anniversary since being instituted, it is important to assess the forces that led to their creation. Whether or not these programs are considered successful depends on what one expects to achieve by such widespread testing. (shrink)

It is shown that both covariant harmonic oscillator formalism and quantum field theory are based on common physical principles which include Poincaré covariance, Heisenberg's space-momentum uncertainty relation, and Dirac's “C-number” time-energy uncertainty relation. It is shown in particular that the oscillator wave functions are derivable from the physical principles which are used in the derivation of the Klein-Nishina formula.

In recent years, there has been an increase in the adoption of Shari’a in Europe and North America as an arbitration protocol for the resolution of potential contractual disputes. In a largely secular Western business environment, this reality raises corporate policy implications for business organizations. In particular, questions are raised about whether Shari’a is by nature too unpredictable—and too dismissive of women’s rights—to be properly and ethically permitted by Western companies as a possible dispute resolution alternative. This article examines the (...) dynamics and factors that are involved as corporate managers decide whether Shari’a arbitration ought to be banned entirely from contractual negotiations. Arguments for and against the inclusion of a Shari’a arbitration clauses in commercial contracts and contract negotiations are presented. The article concludes that while managers should exercise great prudence and consider the moral implications of negotiating arbitration clauses, an organizational ban of the use of faith-informed arbitration generally, or Shari’a in particular, would be neither morally required nor optimally serve the interests of the organization or its stakeholders.

In 2008, Representative John Read of Mississippi recently co-sponsored state legislation that would ban restaurants from serving obese customers. He later admitted that the bill was a publicity stunt,meant to “shed a little light on the number one problem in Mississippi.” Although controversial, Read’s bill exemplifies both the current perception of obesity as a national public health problem and the general sentiment underlying the types of interventions that are being considered to address this issue. The proposed legislation also demonstrates how (...) policymakers can use or, in this case misuse, information about obesity to generate significant discussion on an issue along with ill-conceived legal interventions.Information sharing and the methods used to share best practices are components of the fourth core element of public health legal preparedness.

This article reviews current methods for evaluating models in the cognitive sciences, including theoretically based approaches, such as Bayes factors and minimum description length measures; simulation approaches, including model mimicry evaluations; and practical approaches, such as validation and generalization measures. This article argues that, although often useful in specific settings, most of these approaches are limited in their ability to give a general assessment of models. This article argues that hierarchical methods, generally, and hierarchical Bayesian methods, specifically, can provide a (...) more thorough evaluation of models in the cognitive sciences. This article presents two worked examples of hierarchical Bayesian analyses to demonstrate how the approach addresses key questions of descriptive adequacy, parameter interference, prediction, and generalization in principled and coherent ways.

The spatial dynamics of the optical emission from an array of 50 times 50 individual microcavity plasma devices is investigated. The array is operated in argon and argon-neon mixtures close to atmospheric pressure with an ac voltage. The optical emission is analysed with phase and space resolution. It has been found that the emission is not continuous over the entire ac period, but occurs once per half period. Each of the observed emission phases shows a self-pulsing of the discharge, with (...) several bursts of emission of fixed width and repetition rate. The number of emission bursts depends on applied voltage and frequency. Spatially resolved measurements prove that the emission bursts are formed by overlapping emission pulses from single discharge cavities. Intensity differences between positive and negative half-wave can be interpreted through spatially resolved measurements of single discharge cavities. (shrink)

Although informed consent is important in clinical research, questions persist regarding when it is necessary, what it requires, and how it should be obtained. The standard view in research ethics is that the function of informed consent is to respect individual autonomy. However, consent processes are multidimensional and serve other ethical functions as well. These functions deserve particular attention when barriers to consent exist. We argue that consent serves seven ethically important and conceptually distinct functions. The first four functions pertain (...) principally to individual participants: (1) providing transparency; (2) allowing control and authorization; (3) promoting concordance with participants' values; and (4) protecting and promoting welfare interests. Three other functions are systemic or policy focused: (5) promoting trust; (6) satisfying regulatory requirements; and (7) promoting integrity in research. Reframing consent around these functions can guide approaches to consent that are context sensitive and that maximize achievable goals. (shrink)

Dubourg and Baumard posited that preferences for exploration are the key to the popularity in imaginary worlds. This commentary argues that other forms of exploration may also account for the success and appeal of specific types of imaginary worlds, namely self-exploration within interactive imaginary worlds such as videogames.

While stigmatisation is universal, stigma research in low- and middle-income countries (LMIC) is limited. LMIC stigma research predominantly concerns health-related stigma, primarily regarding HIV/AIDS or mental illness from an adult perspective. While there are commonalities in stigmatisation, there are also contextual differences. The aim of this study in DR Congo (DRC), as a formative part in the development of a common stigma reduction intervention, was to gain insight into the commonalities and differences of stigma drivers (triggers of stigmatisation), facilitators (factors (...) positively or negatively influencing stigmatisation), and manifestations (practices and experiences of stigmatisation) with regard to three populations: unmarried mothers, children formerly associated with armed forces and groups (CAAFAG), and an indigenous population. Group exercises, in which participants reacted to statements and substantiated their reactions, were held with the ‘general population’ (15 exercises, n = 70) and ‘populations experiencing stigma’ (10 exercises, n = 48). Data was transcribed and translated, and coded in Nvivo12. We conducted framework analysis. There were two drivers mentioned across the three populations: perceived danger was the most prominent driver, followed by perceived low value of the population experiencing stigma. There were five shared facilitators, with livelihood and personal benefit the most comparable across the populations. Connection to family or leaders received mixed reactions. If unmarried mothers and CAAFAG were perceived to have taken advice from the general population and changed their stereotyped behaviour this also featured as a facilitator. Stigma manifested itself for the three populations at family, community, leaders and services level, with participation restrictions, differential treatment, anticipated stigma and feelings of scapegoating. Stereotyping was common, with different stereotypes regarding the three populations. Although stigmatisation was persistent, positive interactions between the general population and populations experiencing stigma were shared as well. This study demonstrated utility of a health-related stigma and discrimination framework and a participatory exercise for understanding non-health related stigmatisation. Results are consistent with other studies regarding these populations in other contexts. This study identified commonalities between drivers, facilitators and manifestations—albeit with population-specific factors. Contextual information seems helpful in proposing strategy components for stigma reduction. (shrink)

Since the early 1980’s, with the clinical advent of in vitro fertilization resulting in so-called “test tube babies,” a wide array of ethical considerations and concerns regarding artificial womb technology (AWT) have been described. Recent breakthroughs in the development of extracorporeal neonatal life support by means of AWT have reinitiated ethical interest about this topic with a sense of urgency. Most of the recent ethical literature on the topic, however, pertains not to the more imminent scenario of a physiologically improved (...) method of neonatal care through AWT, but instead to the remote scenario of “complete ectogenesis” that imagines human gestation occurring entirely outside of the womb. This scoping review of the ethical literature on AWT spans from more abstract concerns about complete ectogenesis to more immediate concerns about the soon-to-be-expected clinical life support of what we term the fetal neonate or fetonate. Within an organizing framework of different stages of human gestational development, from conception to the viable premature infant, we discuss both already identified and newly emerging ethical considerations and concerns regarding AWT and the care of the fetonate.

Alzheimer's disease (AD) is the most common cause of dementia, and there is currently no cure. The “β‐amyloid cascade hypothesis” of AD is the basis of current understanding of AD pathogenesis and drug discovery. However, no AD models have fully validated this hypothesis. We recently developed a human stem cell culture model of AD by cultivating genetically modified human neural stem cells in a three‐dimensional (3D) cell culture system. These cells were able to recapitulate key events of AD pathology including (...) β‐amyloid plaques and neurofibrillary tangles. In this review, we will discuss the progress and current limitations of AD mouse models and human stem cell models as well as explore the breakthroughs of 3D cell culture systems. We will also share our perspective on the potential of dish models of neurodegenerative diseases for studying pathogenic cascades and therapeutic drug discovery. (shrink)

This article tracks Corporate Social Responsibility (CSR) as an emergent organizational process that places the employee at its center. Predominantly, research on CSR tends to focus on external pressures and outcomes leading to a neglect of CSR as a dynamic and developing process that relies on the involvement of the employee as a major stakeholder in its co-creation and implementation. Utilizing case study data drawn from a study of a large multinational energy company, we explore how management relies on employees' (...) interaction with CSR as the process of initiation → implementation → maturation develops. Employee involvement grows from a minor element in the CSR initiation stage to a vital contributory factor in CSR's success in the later stages of the process. The article offers new insights into a processual and interactional approach to CSR that accounts for the actions of different actors involved at each stage. Most unusually, it also recognizes the dual impact this has on broader issues concerning the management and involvement of employees through CSR actions, and gaining legitimacy in the eyes of not only external stakeholders but internal too.
