BackgroundBayesian estimation with informative priors permits updating previous findings with new data, thus generating cumulative knowledge. To reduce subjectivity in the process, the present study emphasizes how to systematically weigh and specify informative priors and highlights the use of different aggregation methods using an empirical example that examined whether observed mother-adolescent positive and negative interaction behavior mediate the associations between maternal and adolescent internalizing symptoms across early to mid-adolescence in a 3-year longitudinal multi-method design.MethodsThe sample consisted of 102 mother-adolescent dyads. (...) Mothers and adolescents reported on their internalizing symptoms and their interaction behaviors were observed during a conflict task. We systematically searched for previous studies and used an expert-informed weighting system to account for their relevance. Subsequently, we aggregated the priors using three methods: linear pooling, logarithmic pooling, and fitting a normal distribution to the linear pool by means of maximum likelihood estimation. We compared the impact of the three differently specified informative priors and default priors on the prior predictive distribution, shrinkage, and the posterior estimates.ResultsThe prior predictive distributions for the three informative priors were quite similar and centered around the observed data mean. The shrinkage results showed that the logarithmic pooled priors were least affected by the data. Most posterior estimates were similar across the different priors. Some previous studies contained extremely specific information, resulting in bimodal posterior distributions for the analyses with linear pooled prior distributions. The posteriors following the fitted normal priors and default priors were very similar. Overall, we found that maternal, but not adolescent, internalizing symptoms predicted subsequent mother-adolescent interaction behavior, whereas negative interaction behavior seemed to predict subsequent internalizing symptoms. Evidence regarding mediation effects remained limited.ConclusionA systematic search for previous information and an expert-built weighting system contribute to a clear specification of power priors. How information from multiple previous studies should be included in the prior depends on theoretical considerations, and may also be affected by pragmatic considerations regarding the impact of the previous results at hand.

The COVID-19 lockdown has significantly disrupted the higher education environment within the Netherlands and led to changes in available study-related resources and study demands of students. These changes in study resources and study demands, the uncertainty and confusion about educational activities, the developing fear and anxiety about the disease, and the implementation of the COVID-19 lockdown measures may have a significant impact on the mental health of students. As such, this study aimed to investigate the trajectory patterns, rate of change, (...) and longitudinal associations between study resources–demands and mental health of 141 university students from the Netherlands before and during the COVID-19 lockdown. The present study employed a longitudinal design and a piecewise latent growth modeling strategy to investigate the changes in study resources and mental health over a 3 month period. The results showed that moderate levels of student resources significantly decreased before, followed by a substantial rate of increase during, lockdown. In contrast, study demands and mental health were reported to be moderate and stable throughout the study. Finally, the growth trajectories of study resources–demands and mental health were only associated before the lockdown procedures were implemented. Despite growing concerns relating to the negative psychological impact of COVID-19 on students, our study shows that the mental health during the initial COVID-19 lockdown remained relatively unchanged.

The aim of this research was to gain insight into the experiences and perspectives of individual members of a Medical Research Ethics Committee regarding their individual roles and possible tensions within and between these roles. We conducted a qualitative interview study among members of a large MREC, supplemented by a focus group meeting. Respondents distinguish five roles: protector, facilitator, educator, advisor and assessor. Central to the role of protector is securing valid informed consent and a proper risk-benefit analysis. The role (...) of facilitator implies that respondents want to think along with and assist researchers in order to help medical science progress. As educators, the respondents want to raise ethical and methodological awareness of researchers. The role of advisor implies that respondents bring in their own expertise. The role of assessor points to contributing to the overall evaluation of the research proposal. Various tensions were identified within and between roles. Within the role of protector, a tension is experienced between paternalism and autonomy. Between the role of protector and facilitator tensions occur when the value of a study is questioned while risks and burdens for the subjects are negligible. Within the role of assessor, a tension is felt between the implicit nature of judgments and the need for more explicit formulations. Awareness of various roles and responsibilities may prevent one-sided views on MREC work, not only by members themselves, but also by researchers. Tensions within and between the roles require reflection by MREC members. (shrink)

The McGurk illusion occurs when listeners hear an illusory percept, resulting from mismatched pairings of audiovisual speech stimuli. Hearing a third percept—distinct from both the auditory and visual input—has been used as evidence of AV fusion. We examined whether the McGurk illusion is instead driven by visual dominance, whereby the third percept, e.g., “da,” represents a default percept for visemes with an ambiguous place of articulation, like/ga/. Participants watched videos of a talker uttering various consonant vowels with and without audios (...) of/ba/. Individuals transcribed the CV they saw or heard. In the V-only condition, individuals predominantly saw “da”/“ta” when viewing CVs with indiscernible POAs. Likewise, in the AV condition, upon perceiving an illusion, they predominantly heard “da”/“ta” for CVs with indiscernible POAs. The illusion was stronger in individuals who exhibited weak/ba/auditory encoding. In Experiment2, we attempted to replicate these findings using stimuli recorded from a different talker. The V-only results were not replicated, but again individuals predominately heard “da”/“ta”/“tha” as an illusory percept for various AV combinations, and the illusion was stronger in individuals who exhibited weak/ba/auditory encoding. These results demonstrate that when visual CVs with indiscernible POAs are paired with a weakly encoded auditory/ba/, listeners default to hearing “da”/“ta”/“tha”—thus, tempering the AV fusion account, and favoring a default mechanism triggered when both AV stimuli are ambiguous.

Common hospital and surgical center responses to the Covid‐19 pandemic included curtailing “elective” procedures, which are typically determined based on implications for physical health and survival. However, in the focus solely on physical health and survival, procedures whose main benefits advance components of well‐being beyond health, including self‐determination, personal security, economic stability, equal respect, and creation of meaningful social relationships, have been disproportionately deprioritized. We describe how female reproduction‐related procedures, including abortion, surgical sterilization, reversible contraception devices and in vitro fertilization, (...) have been broadly categorized as “elective,” a designation that fails to capture the value of these procedures or their impact on women's overall well‐being. We argue that corresponding restrictions and delays of these procedures are problematically reflective of underlying structural views that marginalize women's rights and interests and therefore threaten to propagate gender injustice during the pandemic and beyond. Finally, we propose a framework for triaging reproduction‐related procedures during Covid‐19 that is more individualized, accounts for their significance for comprehensive well‐being, and can be used to inform resumption of operations as well as subsequent restriction phases.

Background:Clinical investigation is a growing field employing increasing numbers of nurses. This has created a new specialty practice defined by aspects unique to nursing in a clinical research context: the objectives, setting, and nature of the nurse–participant relationship. The clinical research nurse role may give rise to feelings of ethical conflict between aspects of protocol implementation and the duty of patient advocacy, a primary nursing responsibility. Little is known about whether research nurses experience unique ethical challenges distinct from those experienced (...) by nurses in traditional patient-care settings.Research objectives:The purpose of the study was to describe the nature of ethical challenges experienced by clinical research nurses within the context of their practice.Research design:The study utilized a qualitative descriptive design with individual interviews.Participants and research context:Participating nurses self-identified as having experienced ethical challenges during screening. The majority were Caucasian, female, and worked in outpatient settings. Approximately 50% had > 10 years of research experience.Ethical considerations:The human subjects review board approved the study. Written informed consent was obtained.Findings:Predominant themes were revealed: the inability to provide a probable good, or/do no harm, and dual obligations. The following patterns and subthemes emerged: conflicted allegiances between protocol implementation, needs of the participant, desire to advance science, and tension between the nurse–patient therapeutic relationship versus the research relationship.Discussion:Participants described ethical challenges specific to the research role. The issues are central to the nurse–participant relationship, patient advocacy, the nurse’s role in implementing protocols, and/or advancing science.Conclusion:Ethical challenges related to the specialized role of clinical research nurses were identified. More research is warranted to fully understand their nature and frequency and to identify support systems for resolution. (shrink)

What does it mean to consider the world of AI through a Christian lens? Rapid developments in AI continue to reshape society, raising new ethical questions and challenging our understanding of the human person. Encountering Artificial Intelligence draws on Pope Francis’ discussion of a culture of encounter and broader themes in Catholic social thought in order to examine how current AI applications affect human relationships in various social spheres and offers concrete recommendations for better implementation. The document also explores questions (...) regarding personhood, consciousness, and the kinds of relationships humans might have with even the most advanced AI. Through these discussions, this book investigates the theoretical and practical challenges to interpersonal encounter raised by the age of AI.

In a recent and provocative paper, Matthew Fisher, Mariel Goddu and Frank Keil (2015) have argued, on the basis of experimental evidence, that ‘searching the internet leads people to conflate information that can be found online with knowledge “in the head”’ (2015, 675), specifically, by inclining us to conflate mere access to information for personal knowledge (2015, 674). This chapter has three central aims. First, we briefly detail Fisher et al.’s results and show how, on the basis of recent work (...) in virtue epistemology (e.g., Tiberius and Walker 1998; Roberts and Wood 2007; Tanesini 2016), their interpretation of the data supports the thesis that searching the internet is conducive to the vice of intellectual arrogance. Second, we argue that this arrogance interpretation of the data rests on an implicit commitment to cognitive internalism. Thirdly, we show how the data can be given a very different explanation in light of the hypothesis of extended cognition (e.g., Clark and Chalmers 1998; Clark 2008) – one which challenges the extent to which Fisher et al. are entitled to insist that subjects are actually conflating access to knowledge for personal knowledge in the first place. We conclude by suggesting how, against the background of extended cognition rather than cognitive internalism, we have some reason to think that searching the internet might actually foster (in certain circumstances) virtuous intellectual humility.

In lieu of an abstract, here is a brief excerpt of the content:Philosophers, Carers, and Psychodramatic GamesCorinne Gal (bio), Alexandre Chapy (bio), Marielle Fau (bio), and Muriel Guaveia (bio)Dear Jonathan D. Moreno,Thank you for the honor of taking the time to comment on the work we do. It is very meaningful for us to be able to talk with you.We, too, see a big difference between philosophers and carers (in the broadest sense) who deal with the suffering of patients (...) and try to find methods to help them. But, if theory is at the service of the clinic, it becomes a formidable asset to refine our therapeutic methods and better understand what is happening to our patients.Indeed, patients suffering from psychosis, severe neurosis … are difficult to accompany and “recalcitrant to therapy by word alone” to use your terms. It is on this point that Ludwig Binswanger distanced himself from psychoanalysis. Binswanger ran a sanatorium in Switzerland (the Bellevue Clinic) and took in patients suffering from this type of psychological pathology. Aware that “the divan” and the analysis of the transference (unconscious) made little progress, he sought other ways of understanding his patients. The work of Edmund Husserl, the founder of the phenomenological movement, and then the work of Martin Heidegger1 fascinated him because they attempted to answer fundamental questions about being. The patients we work with ask themselves and us the same question: What is being? How can we feel existence within ourselves? Binswanger then created daseinsanalysis as an analysis of existence in which he was able to develop, among other dimensions, what he called “artists’ gestures,” including the possibility of (physical) contact with the patients. The body regained existential importance in the therapy.There are also strong similarities between psychiatric phenomenology and the work of Jacob Levy Moreno (2014, p. 214). We would like to quote your work: “ Nonetheless, there were links between them. Heidegger and J.L. shared preoccupation with personal authenticity and meaning [End Page 230] just enough to be considered part of the trends that led to postwar existentialism and fueled the new humanistic psychology, NTL, and encounter groups.”Jacob Levy Moreno’s working methods are much more powerful, allowing us to work as closely as possible with bodily feelings, since the body involved in the action is so present in psychodrama. Because, to this question of being posed by our patients, is linked the body as a felt, sensing body: the body that I am (which differs from the object body). Schizophrenic patients often express, and this is a terrible suffering, that they no longer feel anything, that they no longer feel they exist, that they no longer feel emotions or feelings. They do not know how to be in the world and with others. For us it is a fundamental symptom, as much as hallucinations. We link it to the loss of natural evidence (Blankenburg, 1991), the loss of contact with reality (Minkowski, 1929). Most of the time, in psychodrama, we “externalize” what the patients feel in different roles played by players, which allows us to work at the heart of each person’s difficulties in interaction. Trained in psychodrama by Anne Ancelin Schützenberger, we have to our credit a set of techniques to support the expression of psychodramatic play, a sort of “toolbox.” Depending on the context, the moment of the patient, our own state, we open our toolbox and try to choose and use the technique that best fits the needs of the game, of what we understand about the difficulty of the protagonist or the group. We do not do anything systematic, we are craftsmen. We have chosen to present a very simple game, without any technique used, except for the initial soliloquy, with a stabilized patient suffering from paucisymptomatic forms of schizophrenia. This is to demonstrate how the possibility of encounter, constitutive of existence, is a fundamental dimension of psychodrama.We thank you for the examples you have given us, they will be a source of inspiration and will fill our toolbox.To John Nolte:We thank you very much for your comments which honor us.The aim of the article was to present how the encounter in...

The criterion of truth is the measure of the truthfulness and reliability of our knowledge. It is also the basis for determining the correctness of our concepts and how much our perceptions, ideas, and concepts accord with objective reality. Idealism holds to the idea that the criterion of truth does not involve the integration between theory as created by human intelligence and objective reality, but rather that the criterion of truth involves the "clarity and correctness" of perception, viewpoints, and concepts (...) by the subject. For instance, the Machists 1 think that the criterion of truth is experience, however, they neither interpret experience from a materialistic viewpoint, nor view experience as the result of humans interacting with nature as they reform it. The Machists view experience as a summary of perceptions and as the subjective experience of humans. In this sense, perception must be tested by perception itself. In attempting to escape the trap of solipsism , they proposed "collective experience" as the criterion of truth. According to such a view, anything that involves "common significance," that is, anything acknowledged by everyone, is the truth. Lenin exposed the absurdity of idealist theory by pointing out that by following the view of "socially formed experience" it is very easy to consider as normal the most absurd and farcical notions, such as ghosts, for such beliefs are also a form of human "experience." Religion also possesses a "common significance," for innumerable people believe in ghosts and miracles, etc. Nevertheless, religion does not become the truth because of this. The concept of the "criterion of truth" held by the Machists played a dominant role in modern bourgeois philosophy. Jean Jacques Rousseau and John Dewey, along with other reactionaries in philosophy all denied scientific criteria. They would rather that the masses remain ignorant of how to understand and determine the truth. (shrink)

A. J. Ayer was one of the foremost analytical philosophers of the twentieth century, and was known as a brilliant and engaging speaker. In essays based on his influential Dewey Lectures, Ayer addresses some of the most critical and controversial questions in epistemology and the philosophy of science, examining the nature of inductive reasoning and grappling with the issues that most concerned him as a philosopher. This edition contains revised and expanded versions of the lectures and two additional essays. Ayer (...) begins by considering Hume's formulation of the problem of induction and then explores the inferences on which we base our beliefs in factual matters. In other essays, he defines the three kinds of probability that inform inductive reasoning and examines the various criteria for verifiability and falsifiability. In his extensive introduction, Graham Macdonald discusses the arguments in _Probability and Evidence_, how they relate to Ayer's other works, and their influence in contemporary philosophy. He also provides a brief biographical sketch of Ayer, and includes a bibliography of works about and in response to _Probability and Evidence_. (shrink)
