Promoting the use of contact tracing technology will be an important step in global recovery from the COVID-19 pandemic. Across two studies, we assessed two messaging strategies as motivators of intended contact tracing uptake. In one sample of 1117 Australian adults and one sample of 888 American adults, we examined autonomy-supportive and controlling message framing and the presence or absence of information safety as predictors of intended contact tracing application uptake, using an online randomized 2 × 2 experimental design. The (...) results suggested that the provision of data safety assurances may be key in affecting people’s intentions to use contact tracing technology, an effect we found in both samples regardless of whether messages were framed as autonomy-supportive or controlling. Those in high information safety conditions consistently reported higher intended uptake and more positive perceptions of the application than those in low information safety conditions. In Study 2, we also found that perceptions of government legitimacy related positively to intended application uptake, as did political affiliation. In sum, individuals appeared more willing to assent to authority regarding contact tracing insofar as their data safety can be assured. Yet, public messaging strategies alone may be insufficient to initiate intentions to change behavior, even in these unprecedented circumstances. (shrink)

Disquiet about the research ethics review process has, historically, been anecdotal and often takes the form of ‘atrocity stories’ from researchers about the bureaucratic nature of the application process or inconsistency and capriciousness in decision-making. However, systematic evidence has often been lacking. We analysed 100 decision letters written by NHS research ethics committees. We found evidence of poor communication in the way in which REC decisions were conveyed to applicants. Typos and grammatical mistakes were found in almost 30% of letters; (...) sometimes wording was impolite and demonstrated a lack of respect towards applicants; and there was often lack of clarity about the nature of a revision and whether the revision was compulsory or optional. The analysis provides messages for RECs about how they can improve their practices to establish a more cooperative relationship between researcher and committee through the careful use of language and attention to detail in decision letters.

Nitric oxide (NO) is a pleiotropic signalling molecule that subserves a wide variety of basic cellular functions and also manifests itself pathophysiologically. As regards cancer and its progression, however, the reported role of NO appears surprisingly inconsistent. In this review, we focus on metastasis, the process of cancer cell spread and secondary tumour formation. In a ‘reductionist’ approach, we consider the metastatic cascade to be made up of a series of basic cellular behaviours (such as proliferation, apoptosis, adhesion, secretion migration, (...) invasion and angiogenesis). We evaluate how NO controls such behaviours, in comparison with normal cells. The available information suggests strongly that NO signalling would be expected to regulate these behaviours both positively and negatively and this probably leads to the observed apparent variability in the NO status of cancer cells and tissues. Thus, the role of NO in cancer is more complex than previously thought. A number of suggestions are made, including consideration of novel mechanisms, such as ion channels, in order to achieve a more consistent and integrated understanding of NO signalling in cancer and to realise its clinical potential.

Background A topic of great concern in bioethics is the medical research conducted in poor countries sponsored by wealthy nations. Western drug companies increasingly view Latin America as a proper place for clinical research trials. The region combines a large population, modern medical facilities, and low per capita incomes. Participants from developing countries may have little or non alternative means of treatment other than that offered through clinical trials. Therefore, the provision of a valid informed consent is important. Methods To (...) gain insight about some aspects of the informed consent procedure in a major cancer centre in Mexico, we conducted a three-step evaluation process: 1) a ten point multiple choice survey questionnaires, was used to explore some aspects of the patients' experiences during the informed consent process, 2) researchers' knowledge about specific aspects of the informed consent was evaluated in this study using survey questionnaires; and 3) the comprehensibility, readability and number of pages of the consent forms were analysed. The socioeconomic and educational level of the patients, were also considered. Results were reported using a numerical scale. Results Thirty five patients, 20 doctors, and 10 individuals working at the hospital agreed to participate in the study. Eighty three percent of the patients in the study were classified as living in poverty; education level was poor or non existent, and 31% of the patients were illiterate. The consent forms were difficult to understand according to 49% of the patients, most doctors agreed that the forms were not comprehensible to the patients. The average length of the IC documents analysed was 14 pages, and the readability average score was equivalent to 8TH Grade. Conclusion The results presented in this work describe some relevant characteristics of the population seen at public health care institutions in Mexico. Poverty, limited or no education, and the complexity of the information provided to the patients may question the validity of the informed consent procedure in this group of patients. (shrink)

Life goals or aspirations can be distinguished as intrinsic or extrinsic, with different implications for well-being. In this study we used network analysis to reexamine this intrinsic-extrinsic distinction, illustrating how novel candidate aspirations can be mapped along this dimension using innovative methods. We identify four previously unexamined life aspirations, predicting that aspiring for power and social adherence would group with extrinsic goals, whereas aspiring for self-expression and mastery would group with intrinsic goals. In two samples (n = 196; n = (...) 346) we analyze both the original life-goal variables and these novel aspirations using factor analysis, multidimensional scaling, circumplex modeling, and a network analysis using a graphical least absolute shrinkage and selection operator (glasso) to estimate the network structure of aspirations using EBIC. Replicating past intrinsic-extrinsic distinctions, all four methods further classified power and social adherence as extrinsic goals, and self-expression and mastery as intrinsic goals. The intrinsic-extrinsic distinction was also clearly visible in the network analysis. Finally, consistent with hypotheses, power and social adherence were unrelated to wellness indicators, whereas self-expression and mastery correlated positively with well-being indicators and negatively with ill-being indicators, supporting their hypothesized nature as extrinsic and intrinsic, respectively.

Recently, John Doe, an undocumented immigrant who was detained by United States Immigration and Customs Enforcement, was admitted to a hospital off-site from a detention facility. Custodial officers accompanied Mr. Doe into the exam room and refused to leave as physicians examined him. In this analysis, we examine the ethical dilemmas this case brings to light concerning the treatment of patients in immigration detention and their rights to privacy. We analyze what US law and immigration detention standards allow regarding immigration (...) enforcement or custodial officers’ presence in medical exams and documentation of detainee health information. We describe the ethical implications of the presence of officers in medical exam rooms, including its effects on the quality of the patient-provider relationship, patient privacy and confidentiality, and provider's ability to provide ethical care. We conclude that the presence of immigration enforcement or custodial officers during medical examination of detainees is a breach of the right to privacy of detainees who are not an obvious threat to the public. We urge ICE and the US Department of Homeland Security to clarify standards for and tighten enforcement around when officers are legally allowed to be stationed in medical exam rooms and document detainees’ information.

Academic integrity establishes a code of ethics that transfers over into the job force and is a critical characteristic in scientists in the twenty-first century. A student’s perception of cheating is influenced by both internal and external factors that develop and change through time. For students, the COVID-19 pandemic shrank their academic and social environments onto a computer screen. We surveyed science students in the United States at the end of their first COVID-interrupted semester to understand how and why they (...) believed their peers were cheating more online during a pandemic. Almost 81% of students indicated that they believed cheating occurred more frequently online than in-person. When explaining why they believed this, students touched on proctoring, cheating influences, and extenuating circumstances due to COVID-19. When describing how they believed cheating occurred more frequently online, students touched on methods for cheating and surreptitious behavior. The student reasonings were associated with four theories that have been used to examine academic dishonesty. Our results can aid institutions in efforts to quell student concerns about their peers cheating during emergencies. Interestingly, most student beliefs were mapped to planned behavior theory while only a few students were mapped to neutralization theory, suggesting it was a novel modality of assessment rather than a pandemic that shaped student perceptions.

Human and automated tutors attempt to choose pedagogical activities that will maximize student learning, informed by their estimates of the student's current knowledge. There has been substantial research on tracking and modeling student learning, but significantly less attention on how to plan teaching actions and how the assumed student model impacts the resulting plans. We frame the problem of optimally selecting teaching actions using a decision-theoretic approach and show how to formulate teaching as a partially observable Markov decision process planning (...) problem. This framework makes it possible to explore how different assumptions about student learning and behavior should affect the selection of teaching actions. We consider how to apply this framework to concept learning problems, and we present approximate methods for finding optimal teaching actions, given the large state and action spaces that arise in teaching. Through simulations and behavioral experiments, we explore the consequences of choosing teacher actions under different assumed student models. In two concept-learning tasks, we show that this technique can accelerate learning relative to baseline performance. (shrink)

We examine change across U.S. cohorts born between 1920 and 2000 in their probability of having had sex with same-sex partners in the last year and since age 18. Using data from the 1988–2018 General Social Surveys, we explore how trends differ by gender, race, and class background. We find steep increases across birth cohorts in the proportion of women who have had sex with both men and women since age 18, whereas increases for men are less steep. We suggest (...) that the trends reflect an increasingly accepting social climate, and that women’s steeper trend is rooted in a long-term asymmetry in gender change, in which nonconformity to gender norms is more acceptable for women than men. We also find evidence that, among men, the increase in having had sex with both men and women was steeper for black than for white men, and for men of lower socioeconomic status; we speculate that the rise of mass incarceration among less privileged men may have influenced this trend.

In this consensus report by a diverse group of academics who conduct and/or are concerned about social and behavioral genomics (SBG) research, the authors recount the often‐ugly history of scientific attempts to understand the genetic contributions to human behaviors and social outcomes. They then describe what the current science—including genomewide association studies and polygenic indexes—can and cannot tell us, as well as its risks and potential benefits. They conclude with a discussion of responsible behavior in the context of SBG research. (...) SBG research that compares individuals within a group according to a “sensitive” phenotype requires extra attention to responsible conduct and to responsible communication about the research and its findings. SBG research (1) on sensitive phenotypes that (2) compares two or more groups defined by (a) race, (b) ethnicity, or (c) genetic ancestry (where genetic ancestry could easily be misunderstood as race or ethnicity) requires a compelling justification to be conducted, funded, or published. All authors agree that this justification at least requires a convincing argument that a study's design could yield scientifically valid results; some authors would additionally require the study to have a socially favorable risk‐benefit profile.

Bioethicists frequently call for empirical researchers to engage participants and community members in their research, but don't themselves typically engage community members in their normative research. In this article, we describe an effort to include members of the public in normative discussions about the risks, potential benefits, and ethical responsibilities of social and behavioral genomics (SBG) research. We reflect on what might—and might not— be gained from engaging the public in normative scholarship and on lessons learned about public perspectives on (...) the risks and potential benefits of SBG research and the responsible conduct and communication of such research. We also provide procedural lessons for others in bioethics who are interested in engaging members of the public in their research. (shrink)

The aim of this article is to analyse the internal mechanisms of corporate governance (board of directors and ownership structure), which influence voluntary disclosure of intangibles. The results appear to corroborate the view that an increase in institutional investor shareholding has a negative effect on voluntary disclosure, supporting the hypothesis of entrenchment, whereas an excessive ownership by institutional investors may have adverse effects on strategic disclosure decisions. The results also indicate that an increase in the number of members of the (...) board to up to 15 has a beneficial effect on the disclosure of intangibles. However, as this number increases, the effect inverts and becomes adverse to improving the capacity for supervision and control in the decision-making process regarding the voluntary disclosure of intangibles. The findings endorse the recommendation of the most of the Corporate Governance Codes regarding an advisable maximum of 15 members on a board to ensure its effectiveness and internal cohesion.

Mothers use online resources frequently to obtain information on pregnancy, birth, and parenting. Yet, second-time mothers may have different concerns than first-time mothers given they have a newborn infant and another child at home. The current study conducted an on-line textual analysis of the posts of second-time mothers during pregnancy and the first months postpartum on the BabyCenter LLC website, one of the largest online parenting communities. Latent Dirichlet Allocation analysis on roughly 16,000 posts to BabyCenter birth clubs in 2017 (...) by approximately 4,000 users revealed second-time mothers relied on the online support of the BabyCenter community to share and discuss topics of pregnancy, birth, and child rearing. Second-time mothers also raised questions about preparing their firstborn children for a new baby sibling, how they would care for two children, whether they would love the second one as much as the first, and how the second child would change family dynamics. Future research needs to recognize that second-time mothers may have distinct concerns surrounding the birth of their second baby, and antenatal education and parenting classes may need to be modified to be more inclusive of these women’s needs and perspectives. Online parenting communities offer avenues to support women as they make the transition from one child to two and may provide targeted opportunities to disseminate evidence-based practices that can assist these women and their children.

Consumer demand for health information and health services has rapidly evolved to capture and even propel the movement to online health information seeking. Seventeen percent of health information internet users will look for information about memory loss, dementia and Alzheimer’s disease. We examined the content of the 25 most frequently retrieved websites marketing AD dietary supplements. We found that the majority of websites and their products claimed AD-related benefits, including improvement and enhancement of function, treatment for AD, prevention of AD, (...) maintenance of function, delayed progression of AD, and decreased symptoms. Supplements were described as effective, natural, powerful or strong, dependable and pure or of high quality. Peer reviewed references to proper scientific studies were infrequent on websites. Statements highlighting the risks of dietary supplements were as common as statements mitigating or minimizing these risks. Different strategies were used to promote supplements such as popular appeals and testimonials. Further enforcement of relevant policy is needed and preparation of clinicians to deal with requests of patients and caregivers is indicated. (shrink)

Individuals typically produce auditory sequences, such as speech or music, at a consistent spontaneous rate or tempo. We addressed whether spontaneous rates would show patterns of convergence across the domains of music and language production when the same participants spoke sentences and performed melodic phrases on a piano. Although timing plays a critical role in both domains, different communicative and motor constraints apply in each case and so it is not clear whether music and speech would display similar timing mechanisms. (...) We report the results of two experiments in which adult participants produced sequences from memory at a comfortable spontaneous (uncued) rate. In Experiment 1, monolingual pianists in Buffalo, New York engaged in three production tasks: speaking sentences from memory, performing short melodies from memory, and tapping isochronously. In Experiment 2, English-French bilingual pianists in Montréal, Canada produced melodies on a piano as in Experiment 1, and spoke short rhythmically-structured phrases repeatedly. Both experiments led to the same pattern of results. Participants exhibited consistent spontaneous rates within each task. People who produced one spoken phrase rapidly were likely to produce another spoken phrase rapidly. This consistency across stimuli was also found for performance of different musical melodies. In general, spontaneous rates across speech and music tasks were not correlated, whereas rates of tapping and music were correlated. Speech rates (for syllables) were faster than music rates (for tones) and speech showed a smaller range of spontaneous rates across individuals than did music or tapping rates. Taken together, these results suggest that spontaneous rate reflects cumulative influences of endogenous rhythms (in consistent self-generated rates within domain), peripheral motor constraints (in finger movements across tapping and music), and communicative goals based on the cultural transmission of auditory information (slower rates for to-be-synchronized music than for speech).

This article draws parallels between the representations of the classics of Eurasianism and their contemporaries, namely N. K. Roerich, H. I. Roerich and Y. N. Roerich, on the peculiar mid-world that is formed by Russia within and around it. It is indicated that the concept of interrelation of biogeosystems with peoples and civilizations inhabiting them, defined by the Eurasian term “developmental site”, is familiar from natural-philosophic concepts of the earlier period. In the era of the development of the ideas of (...) noospherism, it obtained natural-scientific substantiation and new interpretation not only in L. N. Gumilyov original theory of ethnogenesis, but also in representations of the Russian cosmism, which can be correlated with the scientific-philosophical, literary-artistic heritage of the Roerichs. Unlike geosophy of the Eurasians, the holistic views of Roerichs imparted a rather synthetic character to the historical science. At the same time, Y. N.Roerich distinguished geopsychology as a research instrument for cross-civilizational dialogue. One of the most remarkable episodes in implementation of the Eurasian vision by the Roerichs was their Central Asian expedition and peacekeeping activity, associated with unification of the peoples of Eurasia on the basis of broad cooperation. The article demonstrates the possibility of synthesizing Eurasian theories, spiritual-ethical teachings, and natural scientific research within the framework of integral philosophy for elaboration on the concept of sustainable development. Besides the need for international cooperation, the cultural-philosophical heritage of the Roerichs, which includes “Living Ethics or the Teaching of Life”, infeasibility of evolution of mankind detached from the planet and Cosmos also received its ontological substantiation. Such an in-depth consideration of the fate of Eurasia by the Roerichs, associated with the civilizational foundations of the crossing “Russia — Mongolia — China — India” and the leading role of Siberia in the future, allows filling the gaps in the construction of the classics of Eurasianism and utilize sociocultural potential of Eurasia to the fullest.

Dans son projet de refondation ontologique du savoir comme dans sa pensée sociale, Simon Frank (1877-1950) accorde une place centrale à l’idée d’unité dans la pluralité désignée par le pronom « nous ». Comment cette réalité d’ordre spirituel, en elle-même inconcevable, permet-elle à Frank d’expliciter à la fois, dans le champ psychique, l’émergence du sujet, dans le champ social, la dynamique interne à l’œuvre dans toute communauté humaine et, dans le champ idéologique, le danger des tendances individualistes et collectivistes qui (...) menacent, selon lui, l’équilibre, par ailleurs toujours instable, entre la vie personnelle intérieure de l’homme et sa participation au monde extérieur?

This dissertation explores arguments and questions related to moral error theory – the idea that morality inevitably involves a fundamental and serious error such that moral judgments and statements never come out true. It is suggested that the truth of error theory remains a non-negligible possibility, and that we for this reason should take a version of moral fictionalism seriously. I begin by defining error theory as the claim that moral judgments are beliefs with moral propositions as content, moral utterances (...) are assertions of moral propositions, and no positive moral proposition is true. Second, after giving an account of J.L. Mackie’s error theory, I argue that neither Richard Joyce’s nor Jonas Olson’s argument for error theory gives us strong reasons to believe it. According to Joyce, moral discourse presupposes non-institutional desire-transcendent reasons and non-institutional categorical requirements. I challenge this claim by arguing that morality can be understood as an institution, and that the assumption that there are non-institutional moral reasons and requirements can be understood as entering pragmatically into moral conversations. According to Olson, moral discourse involves a commitment to irreducibly normative favoring relations between facts and actions. I challenge this claim by challenging Olson’s response to Stephen Finlay’s argument against absolutist accounts of moral discourse. Third, I discuss two objections to error theory, and argue that neither gives us strong reasons to reject it. According to the first objection, which is suggested by Terence Cuneo, error theory entails epistemic error theory, which has problematic consequences. After indicating some possible responses on part of the epistemic error theorist, I challenge the entailment claim by defending Hilary Kornblith’s account of epistemic reasons as hypothetical reasons. According to the second objection, error theory entails normative error theory, which cannot be believed. Although he does not defend this objection, Bart Streumer has given an argument for the unbelievability claim. I challenge Streumer’s argument by suggesting that we might have hypothetical reasons to believe normative error theory and that, properly understood, Streumer’s conclusion is not as radical as it may first appear. Fourth, I discuss what practical implications the discovery that error theory is true would have for first-order moral thinking and discourse. I argue that if this practice is overall non-morally valuable to us, we ought to revise engagement in it on the model of role-playing in live action role-playing games if we find out that error theory is true. Some have claimed that Richard Joyce’s fictionalism encounters problems. I argue that by incorporating the suggestion that engagement in revised moral practice is modeled on role-playing, fictionalism can escape these problems and preserve the benefits of first-order moral practice.

L’importance de la figure d’Empédocle dans le Phèdre a été négligée par les commentateurs. Cet article entend montrer qu’elle permet pourtant de donner un nouvel éclairage au mythe de l’attelage ailé. Son point de départ consiste à mettre en relation une nouvelle interprétation du fragment 29 d’Empédocle, qui identifie le Sphairos à un Éros n’ayant plus d’ailes sur le dos, avec le dépassement du dos du ciel par les âmes ailées qui a lieu dans ce mythe du Phèdre. Le dos (...) du ciel serait en effet la transposition platonicienne de la surface externe du Sphairos évoquée dans le fragment, de sorte que son dépassement équivaudrait à un dépassement du matérialisme empédocléen vers l’intelligible. Quant à Éros, Platon prend sur ce point le contre-pied de la critique empédocléenne de la religion traditionnelle, en en faisant moins le Sphairos que l’élan qui mène au-delà de celui-ci. (shrink)

Experiential evidence shows that pain is associated with common meanings. These include a meaning of threat or danger, which is experienced as immediately distressing or unpleasant; cognitive meanings, which are focused on the long-term consequences of having chronic pain; and existential meanings such as hopelessness, which are more about the person with chronic pain than the pain itself. This interdisciplinary book - the second in the three-volume Meanings of Pain series edited by Dr Simon van Rysewyk - aims to better (...) understand pain by describing experiences of pain and the meanings these experiences hold for the people living through them. The lived experiences of pain described here involve various types of chronic pain, including spinal pain, labour pain, rheumatic pain, diabetic peripheral neuropathic pain, fibromyalgia, complex regional pain syndrome, endometriosis-associated pain, and cancer-related pain. Two chapters provide narrative descriptions of pain, recounted and interpreted by people with pain. Language is important to understanding the meaning of pain since it is the primary tool human beings use to manipulate meaning. As discussed in the book, linguistic meaning may hold clues to understanding some pain-related experiences, including the stigmatisation of people with pain, the dynamics of patient-clinician communication, and other issues, such as relationships between pain, public policy and the law, and attempts to develop a taxonomy of pain that is meaningful for patients. Clinical implications are described in each chapter. This book is intended for people with pain, their family members or caregivers, clinicians, researchers, advocates, and policy makers. (shrink)

This article examines an area of Thessalian mythology and cult surrounding the figures of Thetis the Nereid and Cheiron the centaur. It argues that the pair derive a substantial amount of their characterisation, in ancient narratives, from their mutual association, and that only by studying them together can we receive a full insight into their mythological and religious personae. Thetis and Cheiron are shown to differ significantly with regard to a number of themes, such as their relationship with symbolic topography (...) and the natural landscape of Thessaly and – most strikingly – their kourotrophic roles. Thetis’ strong association with ambiguous nurture is argued to connect with her physical conception, especially her association with the shape-changing sepia, cuttlefish, an association which involves her in the wider ancient discourse of unreliable female beauty. It is also shown that the Thetis of Homeric epic is significantly different from the Thetis found in other ancient narratives.Cet article étudie une partie de la mythologie et du culte thessaliens autour des figures de la Néréide Thétis et du centaure Chiron. Il montre qu’une part importante de leur caractéristiques, dans les récits anciens, provient de leur association et que c’est seulement en les étudiant ensemble qu’on prend la pleine mesure de leur dimension mythologique et religieuse. Thétis et Chiron présentent des différences substantielles sur un certain nombre de plans, tels que leur relation à la topographie symbolique et au paysage naturel de la Thessalie, et, de manière plus surprenante, leur rôle de courotrophes. L’association étroite entre Thétis et l’ambiguïté du nourrissage est mise en relation avec sa constitution physique et avec le sepia protiforme, le poulpe. Cette dernière association l’insère dans un ample discours ancien sur la duplicité de la beauté féminine. En outre, la Thétis de l’épopée homérique est fort différente de la Thétis que l’on trouve dans les autres récits anciens. (shrink)
