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.

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.

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)

Hannah Arendt's work inspires many to stand in solidarity against authoritarianism, racial or gender-based violence, climate change, and right-wing populism. But what if a careful analysis of her oeuvre reveals a darker side to this intellectual legacy? What if solidarity, as she conceives of it, is not oriented toward equality, freedom, or justice for all, but creates a barrier to intersectional coalition building? In Arendt's Solidarity, David D. Kim illuminates Arendt's lifelong struggle with this deceptively straightforward yet divisive concept. Drawing (...) upon her publications, unpublished documents, private letters, radio and television interviews, newspaper clippings, and archival marginalia, Kim examines how Arendt refutes solidarity as an effective political force against anti-Semitism, racial injustice, or social inequality. As Kim reveals, this conceptual conundrum follows the arc of Arendt's forced migration across the Atlantic and is directly related to every major concern of hers: Christian neighborly love, friendship, Jewish assimilation, Zionism, National Socialism, the American republic, Black Power, revolution, violence, and the human world. Kim places these thoughts in dialogue with dissenting voices, such as Thomas Mann, Gershom Scholem, Jean-Paul Sartre, James Baldwin, Frantz Fanon, James Forman, and Ralph Ellison. The result is a full-scale reinterpretation of Arendt's oeuvre. (shrink)

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)

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.

Robust technology infrastructure is needed to enable learning health care systems to improve quality, access, and cost. Such infrastructure relies on the trust and confidence of individuals to share their health data for healthcare and research. Few studies have addressed consumers’ views on electronic data sharing and fewer still have explored the dual purposes of healthcare and research together. The objective of the study is to explore factors that affect consumers’ willingness to share electronic health information for healthcare and research. (...) This study involved a random-digit dial telephone survey of 800 adult Californians conducted in English and Spanish. Logistic regression was performed using backward selection to test for significant associations of each explanatory variable with the outcome variable. The odds of consent for electronic data sharing for healthcare decreased as Likert scale ratings for EHR impact on privacy worsened, odds ratio = 0.74, 95% CI [0.60, 0.90]; security, OR = 0.80, 95% CI [0.66, 0.98]; and quality, OR = 0.59, 95% CI [0.46–0.75]. The odds of consent for sharing for research was greater for those who think EHR will improve research quality, OR = 11.26, 95% CI [4.13, 30.73]; those who value research benefit over privacy OR = 2.72, 95% CI [1.55, 4.78]; and those who value control over research benefit OR = 0.49, 95% CI [0.26, 0.94]. Consumers’ choices about electronically sharing health information are affected by their attitudes toward EHRs as well as beliefs about research benefit and individual control. Design of person-centered interventions utilizing electronically collected health information, and policies regarding data sharing should address these values of importance to people. Understanding of these perspectives is critical for leveraging health data to support learning health care systems. (shrink)

We have developed a formal model of certain types of riddles, and implemented it in a computer program, JAPE, which generates simple punning riddles. In order to test the model, we evaluated the behaviour of the program, by having 120 children aged eight to eleven years old rate JAPE-generated texts, human-generated texts, and non-joke texts for "jokiness" and funniness. This confirmed that JAPE's output texts are indeed jokes, and that there is no significant difference in funniness or jokiness between JAPE"s (...) most comprehensible texts and published human-generated jokes.

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.

This article examined the effects of body–object interaction (BOI) on semantic processing. BOI measures perceptions of the ease with which a human body can physically interact with a word's referent. In Experiment 1, BOI effects were examined in 2 semantic categorization tasks (SCT) in which participants decided if words are easily imageable. Responses were faster and more accurate for high BOI words (e.g., mask) than for low BOI words (e.g., ship). In Experiment 2, BOI effects were examined in a semantic (...) lexical decision task (SLDT), which taps both semantic feedback and semantic processing. The BOI effect was larger in the SLDT than in the SCT, suggesting that BOI facilitates both semantic feedback and semantic processing. The findings are consistent with the embodied cognition perspective (e.g.,, Perceptual Symbols Theory), which proposes that sensorimotor interactions with the environment are incorporated in semantic knowledge.

A superconducting transition temperature as high as 100 K was recently discovered in one monolayer FeSe grown on SrTiO3. The discovery ignited efforts to identify the mechanism for the markedly enhanced Tc from its bulk value of 8 K. There are two main views about the origin of the Tc enhancement: interfacial effects and/or excess electrons with strong electron correlation. Here, we report the observation of superconductivity below 20 K in surface electron-doped bulk FeSe. The doped surface layer possesses all (...) the key spectroscopic aspects of the monolayer FeSe on SrTiO3. Without interfacial effects, the surface layer state has a moderate Tc of 20 K with a smaller gap opening of 4.2 meV. Our results show that excess electrons with strong correlation cannot induce the maximum Tc, which in turn reveals the need for interfacial effects to achieve the highest Tc in one monolayer FeSe on SrTiO3.

Components of artificial intelligence (AI) for analysing social big data, such as natural language processing (NLP) algorithms, have improved the timeliness and robustness of health data. NLP techniques have been implemented to analyse large volumes of text from social media platforms to gain insights on disease symptoms, understand barriers to care and predict disease outbreaks. However, AI-based decisions may contain biases that could misrepresent populations, skew results or lead to errors. Bias, within the scope of this paper, is described as (...) the difference between the predictive values and true values within the modelling of an algorithm. Bias within algorithms may lead to inaccurate healthcare outcomes and exacerbate health disparities when results derived from these biased algorithms are applied to health interventions. Researchers who implement these algorithms must consider when and how bias may arise. This paper explores algorithmic biases as a result of data collection, labelling and modelling of NLP algorithms. Researchers have a role in ensuring that efforts towards combating bias are enforced, especially when drawing health conclusions derived from social media posts that are linguistically diverse. Through the implementation of open collaboration, auditing processes and the development of guidelines, researchers may be able to reduce bias and improve NLP algorithms that improve health surveillance.

Henrich et al. convincingly caution against the overgeneralization of findings from particular human populations, but fail to apply their own compelling reasoning to our nearest living relatives, the great apes. Here we argue that rearing history is every bit as important for understanding cognition in other species as it is in humans.

Editors’ Note:As a matter of policy, the editors believe that publishing several reviews of selected texts is a valuable exercise which will enable a cross-section of views to be aired. The recently published second edition of the National Academy of Sciences’ report “On Being a Scientist” was considered an appropriate text for such treatment. The reviewer, Kenneth D. Pimple, Ph.D., is a Research Associate at the Poynter Center for the Study of Ethics and American Institutions and a Visiting Lecturer in (...) the American Studies Program, both at Indiana University. He has been involved with training faculty members to teach ethics since 1989 and is the project director of “Teaching Research Ethics: A Workshop at Indiana University,” with funding from the Department of Education’s Fund for the Improvement of Postsecondary Education. Her interests include nerve development and regeneration. Her research is in the area of analytical chemistry and emphasizes spectroscopic techniques. (shrink)

Recent years have seen increasing calls by a few scientists, largely from the Global North, to explore “solar geoengineering,” a set of speculative technologies that would reflect parts of incoming sunlight back into space and, if deployed at planetary scale, have an average cooling effect. Numerous concerns about the development of such speculative technologies include the many ecological risks and uncertainties as well as unresolved questions of global governance and global justice. This essay starts with the premise that solar geoengineering (...) at planetary scale is unlikely to be governable in a globally inclusive and just manner. Thus, the ethically sound approach is to pursue governance that leads to the nonuse of planetary solar geoengineering. Yet is such a prohibitory agreement feasible, in the face of possible opposition by a few powerful states and other interests? Drawing on social science research and a host of existing transnational and international governance arrangements, this essay offers three illustrative pathways through which a nonuse norm for solar geoengineering could emerge and become diffused and institutionalized in global politics: (1) civil society-led transnational approaches; (2) regionally led state and civil society hybrid approaches; and (3) like-minded or “Schengen-style” club initiatives led by states.

BackgroundThe merits and drawbacks of moral relevance models of addiction have predominantly been discussed theoretically, without empirical evidence of these potential effects. This study develops and evaluates a novel survey measure for assessing moral evaluations of patient substance misuse (ME-PSM).MethodsThis measure was tested on 524 health professionals (i.e., physicians, nurses, and other health professionals) in California (n = 173), urban France (n = 102), and urban China (n = 249). Demographic factors associated with ME-PSM were investigated using analyses of variance (...) (ANOVAs) and t-tests, with results suggesting that ME-PSM is higher among younger health professionals, nurses (when compared with physicians and other health professionals), and Chinese health professionals (when compared with French and American health professionals).ResultsResults provide preliminary support for the psychometric quality of the survey measure introduced in this study, including the existence of a single latent structure and partial invariance of collected data across countries.ConclusionThe survey measure for ME-PSM which was developed and tested in the current study appears to hold potential utility for use as a measure of moral views of patient substance misuse. With development, this measure may be used to examine moral evaluations, both as factors of stigma and of other clinical factors associated with the treatment of patients with substance use disorders.

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.

Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in our sample (...) – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)

Anthony Collins’Discourse on Freethinking(1713) claims an equal right of examining freely any proposition for each human being. However, the right he claims isn’t always clear, and a close reading shows that, in fact, he successively defends three versions of this right, each weighing the role of equality differently. In the first section, where both values appear consistent with one another, claimed freedom and equality of rights are, in fact, in tension with one another and Collins hesitates too much to solve (...) anything. Beyond theDiscourse, this exemplifies the early development of a problem that will become increasingly important in the Late Enlightenment. (shrink)

Subthalamic nucleus deep brain stimulation is an established therapy for Parkinson’s disease motor symptoms. The ideal site for implantation within STN, however, remains controversial. While many argue that placement of a DBS lead within the sensorimotor territory of the STN yields better motor outcomes, others report similar effects with leads placed in the associative or motor territory of the STN, while still others assert that placing a DBS lead “anywhere within a 6-mm-diameter cylinder centered at the presumed middle of the (...) STN produces similar clinical efficacy.” These discrepancies likely result from methodological differences including targeting preferences, imaging acquisition and the use of brain atlases that do not account for patient-specific anatomic variability. We present a first-in-kind within-patient demonstration of severe mood side effects and minimal motor improvement in a Parkinson’s disease patient following placement of a DBS lead in the limbic/associative territory of the STN who experienced marked improvement in motor benefit and resolution of mood side effects following repositioning the lead within the STN sensorimotor territory. 7 Tesla magnetic resonance imaging data were used to generate a patient-specific anatomical model of the STN with parcellation into distinct functional territories and computational modeling to assess the relative degree of activation of motor, associative and limbic territories.
