This essay summarizes key insights across the essays in the Hastings Center Report's special report “Time to Rebuild: Essays on Trust in Health Care and Science.” These insights concern trust and trustworthiness as distinct concepts, competence as a necessary but not sufficient input to trust, trust as a reciprocal good, trust as an interpersonal as well as structural phenomena, the ethical impermissibility of seeking to win trust without being trustworthy, building and borrowing trust as distinct strategies, and challenges to trustworthiness (...) posed by the contingent nature of science. Together, these insights stand to advance an area of research that we believe has been historically stymied by conceptual confusion and a long‐standing insistence on treating trust as a purely instrumental good.

Since early 2014, i have studied what life is like for staff in a mental health sanatorium at a Ghanaian prayer camp. I have traveled to the camp on six occasions to observe its rhythms and routines and interview staff about their work. What follows is an informal reflection on the role of prayer camps as a source of mental health care in Ghana. The text is based on my experience conducting the research at the camp, rather than a formal (...) reporting of results. As such, I make minimal references to theoretical frameworks and previous literature and instead have relied on my own field notes and recreated conversations I had with one staff member in particular.Despite longstanding records of human rights abuses, many...

Many health care organizations made public commitments to become antiracist in the wake of George Floyd's murder. These actions raise questions about the appropriateness of health care's engagement in racial justice and social justice movements generally. We argue that health care organizations can be usefully thought of as having two roles: a functional role to care for the sick and a meta‐role as an organizational citizen. Fulfilling the role of citizen may require participating in the pursuit of social justice, including (...) efforts to achieve racial equity. The demands of these two roles will need to be balanced, but the role of organizational citizen has been largely ignored and merits serious attention. (shrink)

The health policy community has a growing interest in the impact of nonmedical determinants of health, such as housing, nutrition, and social supports, on both health outcomes and costs. This interest has been spurred by the Affordable Care Act’s emphasis on prevention, Robert Wood Johnson’s grant‐making focus on a Culture of Health, and an uptick of research demonstrating the potential returns to health care from investments in social services. Much of this policy‐making, grant making, and research has focused on older (...) Americans.The direct policy implications of this strategy can be elusive. It has become clear that more than medicine will be necessary to improve older Americans’ health status. Real improvement likely requires the development of additional social service offerings, including housing that is accessible to people with disabilities, Meals on Wheels‐type nutrition supports, and transportation. But who should bear the costs and control the finances associated with these programs? In this essay, I explore the question of how policy‐makers should consider financing nonmedical investments in older Americans’ health. As the reader will recognize, I stop short of arguing for what will work. Rather, I identify the strands of an emerging strategy—namely, for health care dollars to be diverted into social service programming—and offer several cautions. It may be that policy‐makers still wish to continue down this path, but my hope is that this essay will allow them to so with greater attention to the risks and unintended consequences of that strategy.

For global health academics and practitioners, it can feel as though we are living in a tyranny of partnerships. The primary trappings of professional success in global health—funding and publications—increasingly rely on the presence or absence of institutional partnerships. Funders often require letters of support from collaborators, and the literature routinely lauds partnerships as the "secret sauce" necessary to solve intractable problems. Commonly, the term describes relationships between entities in the Global North and the Global South, serving as a euphemism (...) for relationships that, at their core, are premised on a transfer of resources from the former to the latter. Many partnerships... (shrink)

This research examines the impact of COVID-19 on food security in New York state and the innovative approaches employed by food assistance organizations to help address the changing and increasing demand for their services from March 2020 to May 2021. We examine the case study of New York’s Capital District region through a qualitative approach. We find that there was a sharp increase in utilization of emergency services during spring of 2020, which tapered off in the summer and fall of (...) 2020 but remained above the levels of need seen the previous year. Food assistance organizations quickly adapted to the increased demand for their services and changing conditions to reduce gaps in local food distribution chains: They reorganized and tapped into new sources for volunteers, networked with public and private organizations, and coordinated work with other regional food pantries for maximum impact. The flexibility of food assistance organizations to address the disruptions brought about by the COVID-19 pandemic highlights their critical roles in the U.S. food security environment. While organizations are aware of their shortcomings, constraints, and overall role in the American food system, the majority also expressed that the pandemic presented an opportunity to treat a complex problem together and to enact change. Several stakeholders also shared their hope that strengthening their networks and innovations may facilitate post-pandemic recovery, bring about systemic changes to address root causes of food insecurity, and better serve the communities most vulnerable to hunger and service disruptions.

As clinical trials end, little is understood about how participants exiting from clinical trials approach decisions related to the removal or post-trial use of investigational brain implants, such as deep brain stimulation (DBS) devices. This empirical bioethics study examines how research participants experience the process of exit from research at the end of clinical trials of implanted neural devices. Using a modified grounded theory study design, we conducted semi-structured, in-depth interviews with 16 former research participants from clinical trials of DBS (...) and responsive neurostimulation (RNS). Open-ended questions elicited motivations for joining the trial, understanding of study procedures at the time of initial informed consent, the process of exiting from research, and decisions about device removal or post-trial device use. Thematic analysis identified categories related to: limited preparedness for the end of research participation, straightforwardness of decisions to explant or keep the device, reconciling with the end of research participation, reconciling post-trial expectations, and achieving a sense of closure after exit from research. A preliminary theoretical model describes contextual factors influencing the process and experience of exit from research. Experiences of clinical trial participants should guide research practices to enhance the ethical design and conduct of clinical trials in DBS and other brain devices. (shrink)

In 2013, one year after the enactment of the landmark Mental Health Act, a small team of psychiatrists, psychologists, and statisticians from the University of Ghana Medical School began a controversial field-based randomized-control trial entitled "Joining Forces" at the Mount Horeb prayer camp. Located about 45 minutes outside of Accra, Mt. Horeb is one of the largest and best known prayer camps in Ghana. It is an Evangelical Pentecostal organization whose mission is to "set free those held captive by Satan (...) through a ministry of fasting and prayer". Mount Horeb had a well-documented track record of human... (shrink)

The periodic table represents and organizes all known chemical elements on the basis of their properties. While the importance of this table in chemistry is uncontroversial, the role that it plays in scientific reasoning remains heavily disputed. Many philosophers deny the explanatory role of the table and insist that it is “merely” classificatory (Shapere, in F. Suppe (Ed.) The structure of scientific theories, University of Illinois Press, Illinois, 1977; Scerri in Erkenntnis 47:229–243, 1997). In particular, it has been claimed that (...) the table does not figure in causal explanation because it “does not reveal causal structure” (Woody in Science after the practice turn in the philosophy, history, and social studies of science, Routledge Taylor & Francis Group, New York, 2014). This paper provides an analysis of what it means to say that a scientific figure reveals causal structure and it argues that the modern periodic table does just this. It also clarifies why these “merely” classificatory claims have seemed so compelling–this is because these claims often focus on the earliest periodic tables, which lack the causal structure present in modern versions.

This article argues that notwithstanding Martin Heidegger’s explicit intentions to the contrary, his existential analysis in Being and Time provides more than the mere conditions for the possibility of ethics. More specifically, Heidegger’s account of solicitude, where he distinguishes between leaping in for and leaping ahead of the other, can be read as an account of recognition that has normative implications. This account is developed in light of both Charles Taylor and Axel Honneth’s positions on recognition. It is concluded (...) that Heidegger’s phenomenological elaboration of recognition goes beyond the transcendental aspect of his project of fundamental ontology. (shrink)

This case explores the ethical landscape around recontacting a subject's relatives to return genetic research results when the informed consent form signed by the original cohort of subjects is silent on whether investigators may share new information with the research subject's family. As a result of rapid advances in genetic technology, methods to identify genetic markers can mature during the life course of a study. In this case, the investigators identified the genetic mutation responsible for the disorder after a number (...) of their original subjects had died. The researchers now have the ability to inform relatives of the subject about their risk of developing the same disease. Mark Rothstein, JD, from the University of Louisville School of Medicine, provides an overview of the medical/scientific, legal, and ethical issues underlying this case. Lauren Milner, PhD, and colleagues at Stanford University explore how the relationship between researcher and subject affect this debate. Seema Shah, JD, and colleagues at the National Institutes of Health and University of California, Los Angeles discuss whether and how requirements of the duty to warn are applicable in this case.

According to grounded cognition, words whose semantics contain sensory-motor features activate sensory-motor simulations, which, in turn, interact with spatial responses to produce grounded congruency effects. Growing evidence shows these congruency effects do not always occur, suggesting instead that the grounded features in a word's meaning do not become active automatically across contexts. Researchers sometimes use this as evidence that concepts are not grounded, further concluding that grounded information is peripheral to the amodal cores of concepts. We first review broad evidence (...) that words do not have conceptual cores, and that even the most salient features in a word's meaning are not activated automatically. Then, in three experiments, we provide further evidence that grounded congruency effects rely dynamically on context, with the central grounded features in a concept becoming active only when the current context makes them salient. Even when grounded features are central to a word's meaning, their activation depends on task conditions. (shrink)

In response to Casasanto, Brookshire, and Ivry, we address four points: First, we engaged in conceptual replications of Brookshire, Casasanto, and Ivry, not direct replications. Second, we did not question the validity of Brookshire et al.'s results, nor the similar findings of other researchers, but instead explained divergent findings within an integrated theoretical framework. Third, challenges to the construct of automaticity, including ours, were widespread, long before Brookshire et al.'s article. Fourth, the planned comparisons that we reported tested our theoretical (...) claims and offered strong evidence for them. (shrink)

As the cesarean rate rises in the United States, it is sometimes hailed as a move toward increased safety or increased autonomy. But the industrialization of birth may have consequences which actually decrease women’s autonomy and strip choices away.

DeStefano, Oey, Brockbank, and Vul explore interdisciplinary collaboration using data‐driven measures of research topics and co‐authorship, constructed from a rich dataset of over 11,000 Cogsci conference papers. Findings suggest the cognitive science research community has become increasingly integrated in the last 19 years.

A substantial portion of the developed world's population is increasingly dependent on machines to make their way in the everyday world. For certain privileged groups, computers, cell phones, PDAs, Blackberries, and IPODs, all permitting the faster processing of information, are commonplace. In these populations, even exercise can be automated as persons try to achieve good physical fitness by riding stationary bikes, running on treadmills, and working out on cross-trainers that send information about performance and heart rate.

We investigate whether the disclosure of a firm’s decision to organize as a benefit corporation (BC) rather than a traditional C corporation (CC) influences investors. We survey 136 investors and 57 MBA students and find that they expect BCs to attain higher future corporate social responsibility (CSR) than CCs even when both have equal CSR ratings. Approximately one third of our sample prefers to invest in BCs when CCs have greater financial returns, indicating a willingness by some investors to sacrifice (...) personal financial gain for social good. Our results suggest that investors weight the information contained in BC disclosures as reliable and value-relevant in their investment decisions. We extend the CSR disclosure literature by indicating how investors weight this new type of CSR information, which may affect how BCs fare as publicly traded companies. (shrink)

Background: This article describes the types of community‐wide benefits provided by investigators conducting public health research in South Asia as well as their self‐reported reasons for providing such benefits.Methods: We conducted 52 in‐depth interviews to explore how public health investigators in low‐resource settings make decisions about the delivery of ancillary care to research subjects. In 39 of the interviews respondents described providing benefits to members of the community in which they conducted their study. We returned to our narrative dataset to (...) find answers to two questions: What types of community‐wide benefits do researchers provide when conducting public health intervention studies in the community setting, and what reasons do researchers give when asked why they provided community‐wide benefits?Findings: The types of community‐wide benefits delivered were directed to the health and well‐being of the population. The most common types of benefits delivered were the facilitation of access to health care for individuals in acute medical need and emergency response to natural disasters. Respondents' self‐reported reasons when asked why they provided such benefits fell into 2 general categories: intrinsic importance and instrumental importance. (shrink)

Mechanical devices implanted in the body present implications for broad themes in religious thought and experience, including the nature and destiny of the human person, the significance of a person's embodied experience, including the experiences of pain and suffering, the person's relationship to ultimate reality, the divine or the sacred, and the vocation of medicine. Community-constituting convictions and narratives inform the method and content of reasoning about such conceptual questions as whether a moral line should be drawn between therapeutic or (...) enhancement interventions and/or between somatic and neural/cognitive interventions. By attending to these broader community-forming concepts, it is possible to identify three general orienting themes in religious perspectives on incorporated mechanical devices, which we shall designate as perspectives of “appropriation,” “ambivalence,” and “resistance.”.

Objective:Prior research examining sexual and intimacy concerns among metastatic breast cancer patients and their intimate partners is limited. In this qualitative study, we explored MBC patients’ and partners’ experiences of sexual and intimacy-related changes and concerns, coping efforts, and information needs and intervention preferences, with a focus on identifying how the context of MBC shapes these experiences.Methods:We conducted 3 focus groups with partnered patients with MBC [N = 12; M age = 50.2; 92% White; 8% Black] and 6 interviews with (...) intimate partners [M age = 47.3; 83% White; 17% Black]. Participants were recruited through the Fox Chase Cancer Center Tumor Registry and the Cancer Support Community. Qualitative data were analyzed using the Framework Method and Dedoose software.Results:Qualitative analyses revealed several key themes reflecting ways in which MBC shapes experiences of sex/intimacy: the heavy disease/treatment burden leads to significant, long-term sexual concerns and consequent heightened emotional distress for both patients and partners ; viewing the relationship as having “an expiration date” influences patients’ and partners’ concerns related to sex/intimacy and complicates coping efforts; and information needs extend beyond managing sexual side effects to include emotional aspects of intimacy and the added strain of the life-limiting nature of the disease on the relationship. The heightened severity of sexual concerns faced by patients with MBC, compounded by the terminal nature of the disease, may place patients and partners at risk for significant adverse emotional and interpersonal consequences.Conclusion:Findings suggest unique ways in which sex and intimate relationships change after a diagnosis of metastatic breast cancer from both patients’ and partners’ perspectives. Consideration of the substantial physical and emotional burden of MBC and the broader context of the relationship and intimacy overall is important when developing a sexuality-focused intervention in this population. Addressing sexual concerns is a critical part of cancer care with important implications for patients’ health and quality of life. (shrink)

In the present article, we review the theory and research on religious deconversion with a focus on adolescence and young adulthood. First, we present the relevant terminology (e.g. religious deconversion, religious disaffiliation, and religious deidentification) and statistical trends (e.g. the prevalence of religious Nones and Dones). We define religious deconversion as any movement away from religion. Religiosity decreases across adolescence and into young adulthood, and these developmental periods also have heightened rates of religious deidentification, at least in many Western cultures. (...) Second, we review the theory and research on processes, predictors, and outcomes of religious deconversion. Deconversion is discussed both in terms of individuals becoming less religious and possibly deidentifying from religion. In terms of processes of deconversion, we discuss various theoretical models and self-expressed reasons for deconversion. Religious deconversion tends to progress in phases, often initiated by religious and spiritual struggles. In terms of predictors, we identify predictors at the level of the individual (e.g. demographics, personality, norm-violating behavior, and dimensions of religiosity), family (e.g. parent and family religiosity, family dynamics such as parenting styles, and religious socialization), peers (e.g. peer religiosity and religious conversations with peers), religious communities (e.g. supportiveness, engagement, and dialogue), formal education, and social media. In line with developmental systems perspectives, religious deconversion is a complex and dynamic process involving numerous individual and contextual factors. In terms of outcomes of deconversion, we identify potential individual and relational outcomes that are considered both negative and positive. Finally, we outlined 10 promising future directions for research on religious deconversion. (shrink)

This article serves as an introduction to the special issue on Contemporary Issues in Religious and Spiritual Development in Adolescence, Young Adulthood, and Beyond. First, we give an account of the history of research on religious and spiritual development in adolescence and beyond. Although religion and spirituality have a long history in psychology, it is still an emerging area of research. Second, we summarize the current body of work on religious and spiritual development in adolescence and beyond. Most research in (...) this area has focused on outcomes, particularly religion and spirituality as a protective factor against negative youth outcomes. Some work has also looked at individual and contextual predictors of religion and spirituality. Less is known about processes and trajectories of religious development, particularly in terms of changes in religious identification. Third, we recommend directions for future research in this area. We focus on the need for research to look at the role of religion and spirituality in positive youth development, the religious and spiritual experiences of religious minority youth, religious and spiritual challenges faced by sexual minority youth, and processes and predictors of religious deconversion. Fourth, we outline the four review papers on contemporary issues in religious and spiritual development featured in the special issue. These papers provide literature reviews on four important directions for future research. (shrink)

This study clearly reveals that the benefits ascribed to strategic planning typically are achieved through a variety of means. A formal process that seeks to plan in a comprehensive, linear fashion is likely to be too complicated, politically divisive, expensive and inflexible, and to ignore how decisions are made in a complex, highly decentralised university. While many approaches to planning are used, universities must ensure they provide periodically opportunities for university staff—freed from daily responsibilities—to consider strategic concerns. Accurate and relevant (...) information must be available to all who make and carry out decisions. Planning should be viewed as a learning process rather than a document producing exercise. Extensive communication among university staff and faculty is needed to ensure informed debate and substantial acceptance of decisions—otherwise they are unlikely to be implemented. Perhaps most important is not the process employed but the decision-maker's breadth of perspective and sophistication. No process will overcome lack of competent leadership. The importance of daily decision-making in various councils and committees on issues such as cost containment and budgetary priorities is underestimated in the literature on planning.Critics have doubted whether universities' structures and processes permit them, or their leaders have the resolve, to confront the emerging issues. However, in many respects, the universities' decentralised, multiple decision-making practices may suit them well. They face the same challenging societal changes as other sectors of society. Their staff include some of the most capable individuals in the United States, and in the past they have been highly adaptable during periods of profound social change.Universities do not appear to be less aware of the need to adapt, nor more constrained in adapting to new conditions, than other sectors of society. In fact, university research and scholarship will be highly important in pointing the way for the whole of society to meet this era's challenges. If pessimistic predictions about current trends turn out to be accurate, universities no doubt will adapt at least as well as other kinds of institutions. The travails of business in this environment are daily news! There will be occasional casualties among the universities, as frequently occurs during major social transitions, but institutions that have grown in importance for over 1,000 years, will doubtless emerge from this period perhaps somewhat changed but still performing their historic social functions.

To commemorate 40 years since the founding of the Journal of Business Ethics, the editors in chief of the journal have invited the editors to provide commentaries on the future of business ethics. This essay comprises a selection of commentaries aimed at creating dialogue around the theme The Ethics and Politics of Academic Knowledge Production. Questions of who produces knowledge about what, and how that knowledge is produced, are inherent to editing and publishing academic journals. At the Journal of Business (...) Ethics, we understand the ethical responsibility of academic knowledge production as going far beyond conventions around the integrity of the research content and research processes. We are deeply aware that access to resources, knowledge of the rules of the game, and being able to set those rules, are systematically and unequally distributed. One could ask the question “for whom is knowledge now ethical’”? (See the Burrell commentary.) We have a responsibility to address these inequalities and open up our journal to lesser heard voices, ideas, and ways of being. Our six commentators pursue this through various aspects of the ethics and politics of academic knowledge production. Working with MacIntyre’s scheme of practices and institutions, Andrew West provides commentary on the internal good of business ethics learning and education. Inviting us to step out of the cave, Christopher Michaelson urges a clear-eyed, unblinking focus on the purposes and audiences of business ethics scholarship. As developmental editor, Scott Taylor uncovers some of the politics of peer review with the aim of nurturing of unconventional research. Mike Hyman presents his idiosyncratic view of marketing ethics. In the penultimate commentary, Julie Nelson attributes difficulties in the academic positioning of the Business Ethics field to the hegemony of a masculine-centric model of the firm. And finally, Gibson Burrell provides a powerful provocation to go undercover as researcher-investigators in a parallel ethics of the research process. (shrink)

Answering important public health questions often requires collection of sensitive information about individuals. For example, our understanding of how HIV is transmitted and how to prevent it only came about with people's willingness to share information about their sexual and drug-using behaviors. Given the scientific need for sensitive, personal information, researchers have a corresponding ethical and legal obligation to maintain the confidentiality of data they collect and typically promise in consent forms to restrict access to it and not to publish (...) identifying data.The interests of others, however, can threaten researchers' promises of confidentiality when legal demands are made to access research data. In some cases, the subject of the litigation is tightly connected to the research questions, and litigants' interest in the data is not surprising. Researchers conducting studies on tobacco or occupational or other chemical exposures, for example, are relatively frequent targets of subpoenas. (shrink)

This article is an attempt to develop a measure of ethical sensitivity to racial and gender intolerance that occurs in schools. Acts of intolerance that indicate ethically insensitive behaviors in American schools were identified and tied to existing professional ethical codes developed by school-based professional organizations. The Racial Ethical Sensitivity Test consists of 5 scenarios that portray acts of racial intolerance and ethical insensitivity. Participants viewed 2 videotaped scenarios and then responded to a semistructured interview protocol adapted from Bebeau and (...) Rest. After a 2-week interval, this procedure was repeated. Stability of the REST across time was determined by using the overall test-retest coefficient. Internal as well as interrater consistency was also calculated for each scenario. Overall findings indicate promise for the REST as a reliable measure to assess racial and ethnic sensitivity. (shrink)

This article presents data from the Growing up with Media study related to the implementation of a risk reduction protocol that resulted in three groups of youth: low-risk youth (no flags), youth flagged because of violence involvement and not clinically referred; and flagged youth who were referred to a team clinician due to additional risk considerations. Data are from 3,979 US youth 14–15 years of age recruited through social media between October 2018-August 2019. Four in ten youth were flagged for (...) review. Findings suggest that this methodology of identifying and reviewing cases appears to be working as intended: Not only did referred youth have more flags than non-referred youth, but post-hoc analyses suggested that these youth also had higher rates of psychosocial problems (e.g., non-victimization adversity, substance use, and depressed mood). The implementation of a risk reduction protocol such as the one described in this article adds a layer of human subject protection beyond the more standard list of websites and hotlines provided to all participants in most studies. This protocol leads the way for future studies to recreate a similar process to address concerning responses collected from survey research. (shrink)

Everyone, it seems, is talking and arguing about Evidence-Based Practice. Those therapies and assessments designated as EBP increasingly determine what is taught, researched, and reimbursed in health care. But exactly what is it, and how do you do it? The second edition of Clinician's Guide to Evidence-Based Practices is the concise, practitioner-friendly guide to applying EBPs in mental health. Step-by-step it explains how to conduct the entire EBP process-asking the right questions, accessing the best available research, appraising the research, translating (...) that research into practice, integrating that research with clinician expertise and patient characteristics, evaluating the entire enterprise, attending to the ethical considerations, and when done, moving the EBP process forward by teaching and disseminating it. This book will help you:. Formulate useful questions that research can address. Search the research literature efficiently for best practices. Make sense out of the research morass, sifting wheat from chaff. Incorporate patient values and diversity into the selection of EBP. Blend clinician expertise with the research evidence. Translate empirical research into practice. Ensure that your clients receive effective, research-supported services. Infuse the EBP process into your organizational setting and training methods.

This handbook provides an overview of the research on the changing nature of work and workers by marshalling interdisciplinary research to summarize the empirical evidence and provide documentation of what has actually changed. Connections are explored between the changing nature of work and macro-level trends in technological change, income inequality, global labor markets, labor unions, organizational forms, and skill polarization, among others. This edited volume also reviews evidence for changes in workers, including generational change, that has accumulated across domains. Based (...) on documented changes in work and worker behavior, the handbook derives implications for a range of management functions, such as selection, performance management, leadership, workplace ethics, and employee well-being. This evaluation of the extent of changes and their impact gives guidance on what best practices should be put in place to harness these developments to achieve success. (shrink)

Lysophosphatidic acid (LPA) is a lipid mediator with a wide variety of biological actions, particularly as an inducer of cell proliferation, migration and survival. LPA binds to specific G‐protein‐coupled receptors and thereby activates multiple signal transduction pathways, including those initiated by the small GTPases Ras, Rho, and Rac. LPA signaling has been implicated in such diverse processes as wound healing, brain development, vascular remodeling and tumor progression. Knowledge of precisely how and where LPA is produced has long proved elusive. Excitingly, (...) it has recently been discovered that LPA is generated from precursors by ‘autotaxin’, a once enigmatic exo‐phosphodiesterase implicated in tumor cell motility. Exogenous phospholipases D can also produce LPA, which may contribute to their toxicity. Here we review recent progress in our understanding of LPA bioactivity, signaling and synthesis.
