What I find particularly valuable in the juxtaposition of these three essays on my book is the triangulation made possible by their different versions of much the same story. I present my view as a product of cognitive science, but all three express worries that it may involve some sort of ominous backsliding towards the evils of behaviorism. I agree with Baars and McGovern when they suggest that philosophy has had some baleful influences on psychology during this century. Logical positivism (...) at its best was full of subtle softenings, but behaviorist psychologists bought the tabloid version, and sold it to their students in large quantities. George Miller's account of those dreary days is not an exaggeration, and the effects still linger in some quarters. (Philosophers are often amused--but they should really be disconcerted--to note that the only living, preaching logical positivists today are to be found in psychology departments.). (shrink)

A theme that emerged at the Sheffield Conference with particular force, to my way of thinking, was a new way of recognizing, and then avoiding, a seductive bad idea. One of its many guises is what I have called the Cartesian Theater, but it also appears in the roles of Central Processing, or Central Executive, or Norman and Shallice's SAS, or Fodor's non-modular central arena of belief fixation. What is wrong with this idea is not (just) that it (apparently) postulates (...) an _anatomically_ discernible central region of the brain--maximally non-peripheral, one might say--but that it supposes that there is a functionally identifiable _subsystem_ (however located or even distributed in the brain) that has some all too remarkable competences achieved by some all too remarkable means. There are many routes to it. Here is one that starts off in an excellent direction but then veers off. The mistaken fork is not explicitly endorsed by anybody that I can think of, but I daresay it has covertly influenced a lot of thinking on the topic. (shrink)

In the late 1960s, I created a joke dictionary of philosophers' names that circulated in samizdat form, picking up new entries as it went. The first few editions were on Ditto masters, in those pre-photocopy days. The 7th edition, entitled The Philosophical Lexicon , was the first properly copyrighted version, published for the benefit of the American Philosophical Association in 1978, and the 8th edition (brought out in 1987), is still available from the APA. I continue to receive submissions of (...) further entries, but I doubt that there will ever be a 9th edition. The 8th edition lists two distinct entries for Dick Rorty. (shrink)

The past decades have seen a rise in religious and secular responses to inequality that seek to offer those who are relatively wealthy an opportunity to personally engage with impoverished people and places. This article examines three cases of elite white South Africans who intentionally immersed themselves in poor urban environments. In dialogue with the anthropology of ethics, I argue that immersion was seen as an experimental tool for transforming the self and cultivating virtues of empathy and responsibility towards others. (...) In this way, immersion acted as a technology of the self, linking care of the self to care of others. Yet such experimentation was not without risk. Though imagined as a tool that could promote care of the self and care of others, immersion carries with it the potential to reinforce power divides and/or solicit negative moral judgment. (shrink)

The purpose of this article is to respond to Thomas Uebel’s criticisms of my comments regarding the current revisionism of Carnap’s work and its relations to Kuhn. I begin by pointing out some misunderstandings in the interpretation of my article. I then discuss some aspects related to Carnap’s view of the history of science. First, I emphasize that it was not due to a supposed affinity between Kuhn’s conceptions and those of logical positivists that Kuhn was invited to write the (...) monograph on the history of science for the Encyclopedia. Three other authors had been invited first, including George Sarton whose conception was entirely different from Kuhn’s. In addition, I try to show that Carnap attributes little importance to the history of science. He seldom refers to it and, when he does, he clearly defends a Whig or an ‘old’ historiography of science, to which Kuhn opposes his “new historiography of science”. It is argued that this raises serious difficulties for those, like Uebel, who hold the view that Carnap includes the historical or the social within the rational. (shrink)

Ernst Mach and the Vienna Circle are linked historically, but conceptually the views of Mach do not fit well with logical positivism. My purpose in the present paper is to reconsider 1) Mach’s positive natural philosophy 2) what Mach meant by “anti-metaphysics”, 3) whether Mach really was “anti-metaphysical” in the sense of demanding verification in principle for every term or statement in science, and 4) how Mach’s views on metaphysics differed from those of many Vienna Circle philosophers. I believe a (...) strong case can be made for separating Mach’s realistic version of empiricism from that of the Vienna Circle, but perhaps the “received view” of the Vienna Circle philosophers does not describe their views very well either.

To address the burden of maternal morbidity and mortality in low‐ and middle‐income countries (LMICs), research with pregnant women in these settings is increasingly common. Pregnant women in LMIC‐context may experience vulnerability related to giving consent to participate in a clinical trial. To recognize possible layers of vulnerability this study aims to identify factors that influence the decision process towards clinical trial participation of pregnant women in an urban middle‐income setting. This qualitative research used participant observation, in‐depth interviews, and focus (...) group discussion with medical staff and pregnant women eligible for trial participation, at a regional hospital in Accra, Ghana. Besides lack of familiarity with modern scientific concepts, specific factors influencing the decision‐making process were identified. These include a wide power difference between health provider and patient, and a different perception of risk through externalization of responsibility of risk management within a religious context as well as a context shaped by authority. Also, therapeutic misconception was observed. The combination of these factors ensued women to rely on the opinion of the medical professional, rather than being guided by their own motivation to participation. Although being a (pregnant) woman per se should not render the label of being vulnerable, this study shows there are factors that influence the decision process of pregnant woman towards trial participation in a LMIC context that can result in vulnerability. The identification of context‐specific factors that can create vulnerability facilitates adaptation of the design and conduct of research in a culturally competent manner. (shrink)

Part of the draw of athletics is its straightforwardness. There are nuances to competitions to make them more sporting contests, but at the end of a long jump competition whomever records the longest jump should win. Unfortunately, a recent rule-change at the highest level of the sport – the “Final 3” format – undermined this simplicity for the horizontal jumps and the throws for some of the 2020 and much of the 2021 seasons. While fortunately this rule was largely reverted (...) within days of the initial submission of this paper, it’s still valuable to critically evaluate why such a rule is problematic so as to better understand of the value of sporting competitions and give guidance on future rule changes, be they in athletics or other sports. To that end, we will be drawing from the literature on the purpose and value of competitions and coupling that with simulations based on data from actual top-tier long jump competitions to show that the Final 3 format makes for significantly worse competitions than the standard format.

This chapter presents a science fiction tale in which the author is sent on a bomb‐defusing mission to Tulsa, Oklahoma, by NASA. He recounts his out‐of‐body adventures that test the limits of leading theories of personal identity, especially informational patternism. According to monitoring instruments, something about the nature of the device and its complex interactions with pockets of material deep in the earth had produced radiation that could cause severe abnormalities in certain tissues of the brain. No way had been (...) found to shield the brain from these deadly rays. So it was been decided by NASA that the person sent to recover the device should leave his brain behind. It would be kept in a life‐support lab in a vat in Houston, where it could execute its normal control functions. After the author came out of anesthesia, he asked the inevitable postoperative question: “Where am I?”. (shrink)

George Boolos was one of the most prominent and influential logician-philosophers of recent times. This collection, nearly all chosen by Boolos himself shortly before his death, includes thirty papers on set theory, second-order logic, and plural quantifiers; on Frege, Dedekind, Cantor, and Russell; and on miscellaneous topics in logic and proof theory, including three papers on various aspects of the Gödel theorems. Boolos is universally recognized as the leader in the renewed interest in studies of Frege's work on logic and (...) the philosophy of mathematics. John Burgess has provided introductions to each of the three parts of the volume, and also an afterword on Boolos's technical work in provability logic, which is beyond the scope of this volume.

How many words is a bilingual 2-year-old supposed to know or say in each of her languages? Speech and language therapists or researchers lack the tools to answer this question, because several factors have an impact on bilingual language skills: gender, amount of exposure, mode of acquisition, socio-economic status and the distance between L1 and L2. Unfortunately, these factors are usually studied separately, making it difficult to evaluate their weight on a unique measure of vocabulary. The present study measures the (...) contribution of the following factors to the vocabulary scores of bilingual toddlers: i) gender; ii) sibling ranking; iii) relative amount of exposure to each language; iv) mode of exposure; v) SES; vi) linguistic distance; vii) language spoken between parents. Close to the child’s second birthday, parents of 278 UK-based bilinguals completed successively: a 100-word version of the Oxford-CDI, the CDI in the child’s Additional Language, a family questionnaire, and the Language Exposure Questionnaire. Thirty-six British-English-AL pairs were considered, with languages contrasted on a second-language-learning scale : for example, Dutch and French are close to British-English, while Polish or Cantonese are more distant. Data from the corpus were included in two mixed-effect models, one with the English scores in comprehension as the dependent variable, and the other with production scores. The seven factors listed above were included as predictors. The amount of English exposure was the strongest predictor of comprehension scores = 9.35, p <.005, β = 0.02, t = 3.08, p <.005), followed by the language that parents speak between themselves = 14.94, p <.001, β = 1.37, t = 3.76, p <.0005), linguistic distance = 6.92, p <.01, β = -0.74, t = -2.66, p <.01) and age = 4.86, p <.05, β = 0.55, t = 2.17, p <.05). In production, gender = 13.57, p <.0005, β = -0.91, t = -03.72, p <.0005), amount of exposure to English = 13.57, p <.0005, β = -0.91, t = -03.72, p <.0005), the language that parents speak between themselves = 11.85, p <.005, β = 1.09, t = 3.41, p <.001), and the mother’s occupation = 4.51, p <.05, β = 0.63, t = 2.13, p <.05) were the significant predictors. The more English parents use to address one another, the more English words the child says and understands. This surprising result could be simply explained by the fact that parents who speak English together are also more likely to speak English to their child. The main results of this study is that linguistic distance is a powerful predictor of toddlers’ vocabulary in English, with children learning two close languages growing their vocabulary faster than those learning distant languages.

Varro's De lingua Latina is a treasure trove of information. Of the originally twenty-five books, six have come down to us more or less complete. Among these, Books 5–7 give us many hundreds of etymologies, and Books 8–10 discuss the question whether Latin morphology is regular or not. What Varro rarely comments on is sociolinguistic variation. The sociolinguistic comments in Varro's work can almost be counted on one hand. For instance, in 5.162 Varro remarks that cenaculum, from cena ‘dinner’, means (...) ‘attic’ in Roman Latin, but that the original meaning was, as one might expect, ‘dining-room’, a meaning preserved in the non-Roman dialects of Latium, Falerii and Corduba in Spain; the meaning also lives on in religious uses in Lanuvium. In 7.96, Varro tells us that some words are pronounced with -ae- by some, but with -ē- by others. We know that non-Roman varieties of Latin monophthongized -ae- earlier than the Roman dialect did. Varro mentions pairs like scaena / scēna ‘stage’, a loan from Greek σκηνή, which shows that -ae- is hypercorrect here. Interestingly, only in one such pair is the variant with -ē- ascribed to country people, in the name Maesius / Mēsius, and this is indeed the only pair where the diphthong -ae- is original rather than the result of hypercorrection.

How does microbiota research impact our understanding of biological individuality? We summarize the interdisciplinary summer school on "Microbiota, Symbiosis and Individuality: Conceptual and Philosophical Issues" (July 2019), which was supported by a European Research Council starting grant project "Immunity, DEvelopment, and the Microbiota" (IDEM). The summer school centered around interdisciplinary group work on four facets of microbiota research: holobionts, individuality, causation, and human health. The conceptual discussion of cutting-edge empirical research provided new insights into microbiota and highlights the value of (...) incorporating into meetings experts from other disciplines, such as philosophy and history of science.

Background: Treatment of psychotic disorders in pregnancy is often ethically and clinically challenging, especially when psychotic symptoms impair decision-making capacity. There are several competing ethical obligations to consider: the ethical obligation to maternal autonomy, the maternal and fetal beneficence-based obligations to treat peripartum psychosis, and the fetal beneficence-based obligation to minimize teratogenic exposure. Objective: This article outlines an ethical framework for clinical decision-making for the management of chronic psychosis in pregnancy, with an emphasis on special considerations in the previable and (...) periviable period. Case Presentation: A 31-year-old gravida 2, para 1 with intrauterine pregnancy at 12 weeks and 4 days gestation was brought to the emergency department by her husband seven months after delivering her first child, due to sudden onset of behavioral changes that included self-isolation, not eating, and not taking care of her child. Her past medical history included hypothyroidism and inflammatory bowel disease, but no prior psychiatric illness. After being admitted to the psychiatric hospital, she continued to have poor oral intake and weight loss despite initial inpatient treatment with antipsychotics, levothyroxine, and discontinuation of corticosteroids. Her pregnancy was also complicated by the diagnosis of multiple fetal anomalies at 20 weeks gestation, when the fetus was periviable. Conclusions: For previable or periviable pregnancies, the patient and/or surrogate should decide whether to pursue prenatal genetic screening and invasive diagnostic testing, as well as whether to continue or terminate the pregnancy. When the choice is made to continue the pregnancy, initiation of long-term psychiatric treatment (including medications with potential adverse fetal effects) should be based on shared decision-making between the physician and the patient and/or surrogate. Although some pharmacologic interventions may have potential adverse effects on the developing fetus, the use of psychotropic medications can be ethically justified, even if the patient herself does not have the capacity to consent and requires a surrogate, when the goal is to restore maternal autonomy and minimize the risks of maternal and fetal harm from untreated psychiatric illness.

For the safe and economical construction of embankment dams, the mechanical behaviour of the rockfill materials used in the dam’s shell must be analyzed. The characterization of rockfill materials with specified shear strength is difficult and expensive due to the presence of particles greater than 500 mm in diameter. This work investigates the feasibility of using an extreme gradient boosting computing paradigm to estimate the shear strength of rockfill materials. To train and validate the proposed XGBoost model, a total of (...) 165 databases obtained from the literature are chosen. The XGBoost model was compared against support vector machine, adaptive boosting, random forest, and K-nearest neighbor models described in the literature. XGBoost beats SVM, RF, AdaBoost, and KNN models in terms of performance evaluation metrics such as coefficient of determination, Nash–Sutcliffe coefficient, and error in the root mean square ratio to the standard deviation of the measured data. The results demonstrated that the XGBoost model has the highest prediction performance with, followed by the SVM model with, RF, the AdaBoost model with and the KNN model with. A sensitivity analysis has been conducted to ascertain the impact of each investigated input parameter. This study demonstrates that the established XGBoost model for estimating the shear strength of rockfill materials is reliable. (shrink)

Philosopher Judith Butler has influenced how people talk about vulnerable bodies and sees vulnerability as universal, existential, and relational. Being vulnerable is part of the human condition. The main theoretical areas that run across Butler’s work; power, knowledge and subjectivity, performativity, and ethics—are of particular relevance to nursing practice. This review aims to explore how Butler’s theoretical work is reflected in research literature within a nursing context. We conducted a scoping review guided by Arksey and O’Malley’s methodological framework. A systematic (...) literature search of CINAHL (EBSCOhost), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid), and Web of Science identified 15 papers. Butler’s theoretical work was applied at an individual and social level in research literature within a nursing context. Nurses need to reflect on their clinical practice and role as health professionals in relation to power and performativity in encounters with patients who are marginalized. Nurses’ working conditions, recognition, and understanding are strongly influenced by society, and calling nurses heroes undermines their capacity to challenge and resist the hero identity. The healthcare system’s impact on patient-nurse encounters challenges patients’ and nurses’ subjectivity, performativity, and power relations. The review allowed us to describe how Butler’s theoretical work can facilitate a reflection on nursing practice which is a prerequisite for caring, ethical relationships, and working conditions within a nursing context. Butler’s concepts can provide useful perspectives on how nurses understand, communicate with, and care for patients, as well as a nuanced understanding of the nursing role and power relations and structures.

Various prominent theories of pain assume that it is pain’s biological function to inform organisms about damage to their bodies. I argue that this is a mistake. First, there is no biological evidence to support the notion that pain was originally selected for its informative capacities, nor that it currently contributes to the fitness of organisms in this specific capacity. Second, neurological evidence indicates that modulating mechanisms in the nociceptive system systematically prevent pain from serving a primarily informative role. These (...) considerations threaten to undermine standard perceptual and representational accounts of pain. (shrink)

Hand function improvement in stroke survivors in the chronic stage usually plateaus by 6 months. Brain-computer interface (BCI)-guided robot-assisted training has been shown to be effective for facilitating upper-limb motor function recovery in chronic stroke. However, the underlying neuroplasticity change is not well understood. This study aimed to investigate the whole-brain neuroplasticity changes after 20-session BCI-guided robot hand training, and whether the changes could be maintained at the 6-month follow-up. Therefore, the clinical improvement and the neurological changes before, immediately after, (...) and 6 months after training were explored in 14 chronic stroke subjects. The upper-limb motor function was assessed by Action Research Arm Test (ARAT) and Fugl-Meyer Assessment for Upper-Limb (FMA), and the neurological changes were assessed using resting-state functional magnetic resonance imaging. Repeated-measure ANOVAs indicated that long-term motor improvement was found by both FMA (F[2,26]= 6.367,p= 0.006) and ARAT (F[2,26]= 7.230,p= 0.003). Seed-based functional connectivity analysis exhibited that significantly modulated FC was observed between ipsilesional motor regions (primary motor cortex and supplementary motor area) and contralesional areas (supplementary motor area, premotor cortex, and superior parietal lobule), and the effects were sustained after 6 months. The fALFF analysis showed that local neuronal activities significantly increased in central, frontal and parietal regions, and the effects were also sustained after 6 months. Consistent results in FC and fALFF analyses demonstrated the increase of neural activities in sensorimotor and fronto-parietal regions, which were highly involved in the BCI-guided training.Clinical Trial Registration:This study has been registered atClinicalTrials.govwith clinical trial registration number NCT02323061.

The role of evolutionary theory at the origin of life is an extensively debated topic. The origin and early development of life is usually separated into a prebiotic phase and a protocellular phase, ultimately leading to the Last Universal Common Ancestor. Most likely, the Last Universal Common Ancestor was subject to Darwinian evolution, but the question remains to what extent Darwinian evolution applies to the prebiotic and protocellular phases. In this review, we reflect on the current status of evolutionary theory (...) in origins of life research by bringing together philosophy of science, evolutionary biology, and empirical research in the origins field. We explore the various ways in which evolutionary theory has been extended beyond biology; we look at how these extensions apply to the prebiotic development of (proto)metabolism; and we investigate how the terminology from evolutionary theory is currently being employed in state-of-the-art origins of life research. In doing so, we identify some of the current obstacles to an evolutionary account of the origins of life, as well as open up new avenues of research. (shrink)

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

High-dose chemotherapy and autologous stem cell transplantation is used to treat some advanced malignancies. It is a traumatic procedure, with a high complication rate and significant mortality. ASCT patients and their carers draw on many sources of information as they seek to understand the procedure and its consequences. Some seek information from beyond orthodox medicine. Alternative beliefs and practices may conflict with conventional understanding of the theory and practice of ASCT, and ‘contested understandings’ might interfere with patient adherence to the (...) strict and demanding protocols required for successful ASCT.The present study, conducted in Sydney, Australia, examines narrative-style interviews with 10 sequentially recruited ASCT patients and nine of their carers conducted at the time of transplant and three months later. Transcripts were read for instances of mention of alternative advice, and for instances of contested understanding of information relevant to the transplant.Patients and carer pairs expressed closely concordant views about alternative advice. Five pairs were consulting alternative practitioners. Contested understanding was expressed in four domains—understandings of the transplant itself and its underlying theory, of the relationship between the components of the ‘transplant’, of the nature and role of stem cells, and of beliefs about bodily function and life-style. Contested understandings of the transplant treatment were expressed as predominantly personal interpretations of orthodox informationPatients and carers seemed to recognise that alternative and conventional systems were discordant, yet they were able to separate the two, and adhere to each practice without prejudicing their medical treatment. A single case of late, post-transplant repudiation of Western medicine is discussed to emphasise some of the possible determinants of dissonance when it does occur. (shrink)

The association of resilience-related factors with frailty is a recent research topic. Dispositional optimism and context sensitivity are two psychological factors that differently contribute to individual resilience. This study aimed at investigating whether dispositional optimism and context sensitivity might contribute to a multifactorial model of frailty, together with established relevant factors such as cognitive and physical factors. This cross-sectional study involved 141 elderly outpatients aged ≥65 years, who were referred to the Geriatrics and Multidimensional Evaluation Clinic of the University Hospital (...) of Messina. We used the following measures: the Mini-Mental State Examination to screen for global cognitive functioning; 4-m gait speed and handgrip strength to measure physical performance; a 35-item Frailty Index to evaluate patients’ frailty status; the revised Life Orientation Test to gauge dispositional optimism; and the Context Sensitivity Index to measure context sensitivity. We found that LOT-R, CSI, and MMSE were all significantly associated with FI. Gait speed was only marginally associated with FI. The present study showed a novel association of dispositional optimism and context sensitivity with frailty among elderly outpatients. These preliminary findings support a multidimensional approach to frailty in which even peculiar psychological features might provide a significant contribution. (shrink)

Background: Dementia care at home often involves decisions in which the caregiver must weigh safety concerns with respect for autonomy. These dilemmas can lead to situations where caregivers provide care against the will of persons living with dementia, referred to as involuntary treatment. To prevent this, insight is needed into how family caregivers of persons living with dementia deal with care situations that can lead to involuntary treatment. Objective: To identify and describe family caregivers’ experiences regarding care decisions for situations (...) that can lead to involuntary treatment use in persons living with dementia at home. Research design: A qualitative descriptive interview design. Data were analysed using the Qualitative Analysis Guide of Leuven. Participants and research context: A total of 10 family caregivers providing care for 13 persons living with dementia participated in in-depth semi-structured interviews. Participants were recruited by registered nurses via purposive sampling. Ethical consideration: The study protocol was approved by the Ethics Committee of the University Hospitals Leuven and the Medical Ethical Test Committee Zuyderland. Findings: Family caregivers experience the decision-making process concerning care dilemmas that can lead to involuntary treatment as complicated, stressful and exhausting. Although they consider safety and autonomy as important values, they struggle with finding the right balance between them. Due to the progressive and unpredictable nature of dementia, they are constantly seeking solutions while they adapt to new situations. Family caregivers feel responsible and experience social pressure for the safety of persons living with dementia. They may be blamed if something adverse happens to the persons living with dementia, which increases an already stressful situation. Their experience is influenced by characteristics of the care triad such as practical and emotional support, knowledge, and previous experiences. Discussion and conclusion: To prevent involuntary treatment, professionals need to proactively inform family caregivers, and they need to support each other in dealing with complex care situations.

In this paper, we report on the development and validity of the Professional Decision-Making in Research measure, a vignette-based test that examines decision-making strategies used by investigators when confronted with challenging situations in the context of empirical research. The PDR was administered online with a battery of validity measures to a group of NIH-funded researchers and research trainees who were diverse in terms of age, years of experience, types of research, and race. The PDR demonstrated adequate reliability and parallel form (...) correlation. As hypothesized, the PDR was significantly negatively correlated with narcissism, cynicism, moral disengagement, and compliance disengagement; it was not correlated with socially desirable responding. In regression analysis, the strongest predictors of higher PDR scores were low compliance disengagement, speaking English as a native language, conducting clinical research with human subjects, and low levels of narcissism. Given that the PDR was written at an eighth grade reading level to be suitable for use with English as a second language participants and that only one-fourth of items focused on clinical research, further research into the possible roles of culture and research ethics training across specialties is warranted. This initial validity study demonstrates the potential usefulness of the PDR as an educational outcome assessment measure and a research instrument for studies on professionalism and integrity in research.

23andMe not only sells genetic testing but also uses customer data in its R&D activities and commercial partnerships. This raises questions about transparency and informed consent. Based on a online survey conducted in 2017–18, we examine attitudes of 368 customers of 23andMe toward the company's use of their data. Our findings point at divides in the context of customers' awareness of the two-sided business model of DTC genetics and their attitudes toward consent. While most of our respondents (68%) were aware (...) that 23andMe could store their data and use it for certain purposes without their consent, over 40% were not aware that using and sharing customer data was part of the business model. Views were also divided regarding what type of consent was most appropriate. We explore the implications of these divides for participatory research and for the importance of transparency and trust in commercially-driven scientific knowledge production. (shrink)

The term “lean in” was popularized by Sheryl Sandberg, Facebook COO, via her #1 Best Seller encouraging women to defy their fears and dare to be leaders in their fields. She received criticism because although admitting to external barriers contributing to the gender gap in leadership, the scope of her book focused on the internal shortcomings of women. She asserted that women are hindered by barriers that exist within themselves, and provided practical tips, backed by research, to equip women with (...) strategies to proactively progress in the workplace instead of shying away. Sandberg is not the first to raise concern about gender inequality. Other women in history like Susan B. Anthony and Maggie Lena Walker also challenged lopsided gender roles through their words and actions. Using the critical biography methodology, this paper explores these women’s experiences, philosophies and contributions, reflects on Sandberg’s insight, and develops a framework, based on the theory of planned behavior as well as the ethical principles of utilitarianism and corporate social responsibility, that links internal factors, organizational external factors, and societal external factors to intentions to lean in and leaning in behavior. Thus, via critical biography, this paper examines both internal and external factors, showing how they are linked, and how they may impact leaning in intentions and behavior. The paper also discusses how leaning in may influence both individual and gender mobility for women, and ultimately, increased gender equality. (shrink)

Background: Treating medication-refractory freezing of gait in Parkinson’s disease remains challenging despite several trials reporting improvements in motor symptoms using subthalamic nucleus or globus pallidus internus deep brain stimulation. Pedunculopontine nucleus region DBS has been used for medication-refractory FoG, with mixed findings. FoG, as a paroxysmal phenomenon, provides an ideal framework for the possibility of closed-loop DBS.Methods: In this clinical trial, five subjects with medication-refractory FoG underwent bilateral GPi DBS implantation to address levodopa-responsive PD symptoms with open-loop stimulation. Additionally, PPN (...) DBS leads were implanted for CL-DBS to treat FoG. The primary outcome of the study was a 40% improvement in medication-refractory FoG in 60% of subjects at 6 months when “on” PPN CL-DBS. Secondary outcomes included device feasibility to gauge the recruitment potential of this four-lead DBS approach for a potentially larger clinical trial. Safety was judged based on adverse events and explantation rate.Findings: The feasibility of this approach was demonstrated as we recruited five subjects with both “on” and “off” medication freezing. The safety for this population of patients receiving four DBS leads was suboptimal and associated with a high explantation rate of 40%. The primary clinical outcome in three of the five subjects was achieved at 6 months. However, the group analysis of the primary clinical outcome did not reveal any benefit.Interpretation: This study of a human PPN CL-DBS trial in medication-refractory FoG showed feasibility in recruitment, suboptimal safety, and a heterogeneous clinical effect in FoG outcomes.

BackgroundThe proper and ethical inclusion of PWLHIV and their young children in research is paramount to ensure valid evidence is generated to optimize treatment and care. Little empirical data exists to inform ethical considerations deemed most critical to these populations. Our study aimed to systematically review the empiric literature regarding ethical considerations for research participation of PWLHIV and their young children.MethodsWe conducted this systematic review in partnership with a medical librarian. A search strategy was designed and performed within the following (...) electronic databases: Ovid MEDLINE, Embase and CINAHL. We screened titles and abstracts using the following inclusion criteria: (1) a study population of PWLHIV or children under 5 years of age; and (2) collection of qualitative or quantitative data regarding ethics of research participation. Excluded were reviews, commentaries, policy statements, clinical care-related ethics concerns, abstracts, case studies, or studies unrelated to HIV research. Studies were appraised for quality, data were extracted, and studies were qualitatively analyzed using a principle-based ethical framework within the Belmont Report.ResultsOf the 7470 titles identified, 538 full-text articles were reviewed for eligibility and only three articles met full criteria for inclusion within this review. While we allowed for inclusion of studies involving young children born to mothers with HIV, only articles focused on PWLHIV were identified. Within the results of these studies, four themes emerged: (1) adequacy of informed consent; (2) consideration of paternal involvement; (3) balancing risks; and (4) access to research and treatment. A strength of this review is that it included perspectives of international research investigators, community leaders, and male partners. However, only two studies collected empiric data from PWLHIV regarding their experiences participating in researchConclusionResearchers and funding agencies should be aware of these considerations and appreciate the value of and critical need for formative research to ensure clinical trials involving PWLHIV promote ethical, well-informed research participation and, ultimately, improve care outcomes. More research is needed to create a comprehensive ethical framework for researchers when conducting studies with PWLHIV. (shrink)

Nursing programs are complex systems that articulate values of relationality and holism, while developing curriculums that privilege metric‐driven competency‐based pedagogies. This study used an interpretive approach to analyze interviews from 20 nursing students at two Canadian Baccalaureate programs to understand how nursing's educational context, including its hidden curriculums, impacted student writing activities. We viewed this qualitative data through the lens of activity theory. Students spoke about navigating a rigid writing context. This resulted in a hyper‐focus on “figuring out” the teacher (...) with minimal focus on the act of writing. Students used a form of behavioral “code‐switching” to maximize their grade while considering how their “valuing” of the assignment fit within their writing motives. Hidden curriculum messages taught students that academic success was assured whether their writing mirrored instructor preferences. Instructional practices of rigidity reinforced unequal social conditions for some minority students. Faculty can counteract the impact of the hidden curriculum through encouragement of choice and independent thinking about writing activities. Acknowledging power relationships and their influence on how students navigate writing assignments and nursing discourse may relieve pressures on students who fear penalties for countering norms and result in a more flexible learning environment.

Sustained attention, a key cognitive skill that improves during childhood and adolescence, tends to be worse in some emotional and behavioural disorders. Sustained attention is typically studied in non-affective task contexts; here, we used a novel task to index performance in affective versus neutral contexts across adolescence (N = 465; ages 11–18). We asked whether: (i) performance would be worse in negative versus neutral task contexts; (ii) performance would improve with age; (iii) affective interference would be greater in younger adolescents; (...) (iv) adolescents at risk for depression and higher in anxiety would show overall worse performance; and (v) would show differential performance in negative contexts. Results indicated that participants performed more poorly in negative contexts and showed age-related performance improvements. Those at risk of depression performed more poorly than those at lower risk. However, there was no difference between groups as a result of affective context. For anxiety there was no difference in performance as a function of severity. However, those with higher anxiety showed less variance in their reaction times to negative stimuli than those with lower anxiety. One interpretation is that moderate levels of emotional arousal associated with anxiety make individuals less susceptible to the distracting effects of negative stimuli. (shrink)

Multiple realization was once taken to be a challenge to reductionist visions, especially within cognitive science, and a foundation of the “antireductionist consensus.” More recently, multiple realization has come to be challenged on naturalistic grounds, as well as on more “metaphysical” grounds. Within cognitive science, one focal issue concerns the role of neural plasticity for addressing these issues. If reorganization maintains the same cognitive functions, that supports claims for multiple realization. I take up the reorganization involved in language dysfunctions to (...) deal with questions concerned with multiple realization and neural plasticity. Beginning with Broca’s case for localization and the nineteenth century discussion of “reorganization,” and returning to more recent evidence for neural plasticity, I argue that, in the end, there is substantial support for multiple realization in cognitive systems; I further argue that this is wholly consistent with a recognition of methodological pluralism in cognitive science.

Between 2013 and 2016, West Africa experienced the largest ever outbreak of Ebola Virus Disease. In the absence of registered treatments or vaccines to control this lethal disease, the World Health Organization coordinated and supported research to expedite identification of interventions that could control the outbreak and improve future control efforts. Consequently, the World Health Organization Research Ethics Review Committee was heavily involved in reviews and ethics discussions. It reviewed 24 new and 22 amended protocols for research studies including interventional (...) and observational studies. WHO-ERC provided the reviews within on average 6 working days. The WHO-ERC often could not provide immediate approval of protocols for reasons which were not Ebola Virus Disease specific but related to protocol inconsistencies, missing information and complex informed consents. WHO-ERC considerations on Ebola Virus Disease specific issues are presented. To accelerate study approval in future public health emergencies, we recommend: internally consistent and complete submissions with information documents in language participants are likely to understand, close collaboration between local and international researchers from research inception, generation of template agreements for data and sample sharing and use during the ongoing global consultations on bio-banks, formation of Joint Scientific Advisory and Data Safety Review Committees for all studies linked to a particular intervention or group of interventions, formation of a Joint Ethics Review Committee with representatives of the Ethics Committees of all institutions and countries involved to strengthen reviews through the different perspectives provided without the ‘opportunity costs’ for time to final approval of multiple, independent reviews, direct information exchange between the chairs of advisory, safety review and ethics committees, more Ethics Committee support for investigators than is standard and a global consultation on criteria for inclusion of pregnant women and children in interventional studies for conditions which put them at particularly high risk of mortality or other irreversible adverse outcomes under standard-of-care.

Contextual emergence was originally proposed as an inter-level relation between different levels of description to describe an epistemic notion of emergence in physics. Here, we discuss the ontic extension of this relation to different domains or levels of physical reality using the properties of temperature and molecular shape as detailed case studies. We emphasize the concepts of stability conditions and multiple realizability as key features of contextual emergence. Some broader implications contextual emergence has for the foundations of physics and cognitive (...) and neural sciences are given in the concluding discussion. Relevant facts about algebras of observables are found in the appendices along with an abstract definition of Kubo-Martin-Schwinger states. (shrink)

With fundamentalists dominating the headlines and scientists arguing about the biological and neurological basis of faith, religion is the topic of the day. But religion, Mark C. Taylor shows, is more complicated than either its defenders or critics think and, indeed, is much more influential than any of us realize. Our world, Taylor maintains, is shaped by religion even when it is least obvious. Faith and value, he insists, are unavoidable and inextricably interrelated for believers and nonbelievers alike. Using scientific (...) theories of dynamical systems and complex adaptive networks for cultural and theological analysis, After God redefines religion for our contemporary age. Taylor begins by asking a critical question: What is religion? He then proceeds to explain how Protestant ideas in particular undergird the character and structure of our global information society—the Reformation, Taylor argues, was an information and communications revolution that effectively prepared the way for the media revolution at the end of the twentieth century. Taylor’s breathtaking account of religious ideas allows us to understand for the first time that contemporary notions of atheism and the secular are already implicit in classical Christology and Trinitarian theology. Weaving together theoretical analysis and historical interpretation, Taylor demonstrates the codependence and coevolution of traditional religious beliefs and practices with modern literature, art, architecture, information technologies, media, financial markets, and theoretical biology. After God concludes with prescriptions for new ways of thinking and acting. If we are to negotiate the perils of the twenty-first century, Taylor contends, we must refigure the symbolic networks that inform our policies and guide our actions. A religion without God creates the possibility of an ethics without absolutes that leads to the promotion of creativity and life in an ever more fragile world. The first comprehensive theology of culture since the pioneering work of Paul Tillich, After God is a radical reconceptualization of religion and Taylor’s most pathbreaking work yet, bringing together various strands of theological argument and cultural analysis four decades in the making.

The central nervous system uses feedback processes that occur at multiple time scales to control interactions with the environment. The long-latency response is the fastest process that directly involves cortical areas, with a motoneuron response measurable 50 ms following an imposed limb displacement. Several behavioral factors concerning perturbation mechanics and the active role of muscles prior or during the perturbation can modulate the long-latency response amplitude in the upper limbs, but the interactions among many of these factors had not been (...) systematically studied before. We conducted a behavioral study on thirteen healthy individuals to determine the effect and interaction of four behavioral factors – background muscle torque, perturbation direction, perturbation velocity, and task instruction – on the LLRa evoked from the flexor carpi radialis and extensor carpi ulnaris muscles after velocity-controlled wrist displacements. The effects of the four factors were quantified using both a 0D statistical analysis on the average perturbation-evoked EMG signal in the period corresponding to an LLR, and using a timeseries analysis of EMG signals. All factors significantly modulated LLRa, and their combination nonlinearly contributed to modulating the LLRa. Specifically, all the three-way interaction terms that could be computed without including the interaction between instruction and velocity significantly modulated the LLR. Analysis of the three-way interaction terms of the 0D model indicated that for the ECU muscle, the LLRa evoked when subjects are asked to maintain their muscle activation in response to the perturbations was greater than the one observed when subjects yielded to the perturbations, but this effect was not measured for muscles undergoing shortening or in absence of background muscle activation. Moreover, higher perturbation velocity increased the LLRa evoked from the stretched muscle in presence of a background torque, but no effects of velocity were measured in absence of background torque. Also, our analysis identified significant modulations of LLRa in muscles shortened by the perturbation, including an interaction between torque and velocity, and an effect of both torque and velocity. The time-series analysis indicated the significance of additional transient effects in the LLR region for muscles undergoing shortening. (shrink)

Pets often factor in older adults’ health behaviors and decisions. However, the degree to which issues related to pet ownership are encountered or addressed by professionals working with this population remains unknown. The aim of this study was to identify specific issues stemming from pet ownership professionals had encountered in their work with older adults, people living with dementia, and care partners. An interdisciplinary sample completed an online survey addressing pet ownership issues encountered in their work. Descriptive statistics, t-tests, and (...) repeated measures ANOVAs were used to analyze quantitative data. A conventional content analysis was used to analyze open-ended responses to an item asking about “other” issues encountered in their work with these populations. The professionals estimated 46.29% of clients had been pet owners, 41.23% regularly asked about pets, and 79.22% had encountered issues related to pet ownership. Specific issues raised to the professionals varied by type of client. The professionals reported older adults most often raised getting pet items into the home and concerns about their pets’ health. The issues most often raised by people living with dementia to the professionals were planning for the pet due to a housing transition and basic pet care. Care partners focused on basic pet care and planning for the pet due to a housing transition. The professionals themselves most often raised the issues of basic pet care, concerns about falling, and the pets’ behavior. Professionals who entered clients’ homes were more likely to raise issues stemming from pet ownership compared to those who reported they did not enter clients’ homes in their current job, t = 5.59, p < 0.00001. The eleven new issues identified by the content analysis underscored how the health and wellbeing of people and their pets are linked. The results of this study provide strong evidence that professionals do encounter issues related to pet ownership. Including issues stemming from pet ownership into procedures, policies, and programs is likely to have positive impacts on those served by and working in the geriatric workforce. (shrink)

Background Voluntary post-mortem donation to science (PDS) is the most appropriate source for body dissection in medical education and training, and highly useful for biomedical research. In Mexico, unclaimed bodies are no longer a legal source, but PDS is legally possible, although scarcely facilitated, and mostly ignored by the general population. Therefore, we aimed to evaluate the attitude and willingness for PDS and to identify a sociodemographic profile of people with willingness toward PDS. Methods A validated on-line survey was distributed (...) by the convenience method via the social networks of a Catholicism-inspired, private university in northern Mexico. Frequency analyses of all variables and coded free comments were complemented with association studies. Results Although the responder cohort (n = 143) was too small and biased to be representative of the university community (n = 13,500), willingness to post-mortem organ donation was 90.7% and to PDS 70.7%. In this cohort, PDS willingness had the strongest association with mature age (> 40 years old; P, 0.0008). Among young adults, willingness to PDS was the lowest among volunteers from technical and business schools and the highest among those from the social sciences (P, 0.009). Respondents from the social sciences were also the most consistent between attitude and behavior with respect to organ donation. A free comment option revealed respondents were interested in the unusual taboo topic. Conclusions A small, but sufficiently large proportion expressed willingness toward PDS. In our university cohort, which was biased in higher education and altruism, mature age and social interest were associated with PDS willingness. (shrink)

The ipsilesional arm of stroke patients often has functionally limiting deficits in motor control and dexterity that depend on the side of the brain that is lesioned and that increase with the severity of paretic arm impairment. However, remediation of the ipsilesional arm has yet to be integrated into the usual standard of care for upper limb rehabilitation in stroke, largely due to a lack of translational research examining the effects of ipsilesional-arm intervention. We now ask whether ipsilesional-arm training, tailored (...) to the hemisphere-specific nature of ipsilesional-arm motor deficits in participants with moderate to severe contralesional paresis, improves ipsilesional arm performance and generalizes to improve functional independence. We assessed the effects of this intervention on ipsilesional arm unilateral performance [Jebsen–Taylor Hand Function Test ], ipsilesional grip strength, contralesional arm impairment level [Fugl–Meyer Assessment ], and functional independence [Functional independence measure ]. Intervention occurred over a 3 week period for 1.5 h/session, three times each week. All sessions included virtual reality tasks that targeted the specific motor control deficits associated with either left or right hemisphere damage, followed by graded dexterity training in real-world tasks. We also exposed participants to 3 weeks of sham training to control for the non-specific effects of therapy visits and interactions. We conducted five test-sessions: two pre-tests and three post-tests. Our results indicate substantial improvements in the less-impaired arm performance, without detriment to the paretic arm that transferred to improved functional independence in all three posttests, indicating durability of training effects for at least 3 weeks. We provide evidence for establishing the basis of a rehabilitation approach that includes evaluation and remediation of the ipsilesional arm in moderately to severely impaired stroke survivors. This study was originally a crossover design; however, we were unable to complete the second arm of the study due to the COVID-19 pandemic. We report the results from the first arm of the planned design as a longitudinal study. (shrink)

BackgroundIn December 2014, China announced that only voluntarily donated organs from citizens would be used for transplantation after January 1, 2015. Many medical professionals worldwide believe that China has stopped using organs from death-row prisoners.DiscussionIn the present article, we briefly review the historical development of organ procurement from death-row prisoners in China and comprehensively analyze the social-political background and the legal basis of the announcement. The announcement was not accompanied by any change in organ sourcing legislations or regulations. As a (...) fact, the use of prisoner organs remains legal in China. Even after January 2015, key Chinese transplant officials have repeatedly stated that death-row prisoners have the same right as regular citizens to “voluntarily donate” organs. This perpetuates an unethical organ procurement system in ongoing violation of international standards.ConclusionsOrgan sourcing from death-row prisoners has not stopped in China. The 2014 announcement refers to the intention to stop the use of organs illegally harvested without the consent of the prisoners. Prisoner organs procured with “consent” are now simply labelled as “voluntarily donations from citizens”. The semantic switch may whitewash sourcing from both death-row prisoners and prisoners of conscience. China can gain credibility only by enacting new legislation prohibiting use of prisoner organs and by making its organ sourcing system open to international inspections. Until international ethical standards are transparently met, sanctions should remain. (shrink)

The coronavirus disease 2019 pandemic is altering dynamics in academia, and people juggling remote work and domestic demands – including childcare – have felt impacts on their productivity. Female authors have faced a decrease in paper submission rates since the beginning of the pandemic period. The reasons for this decline in women’s productivity need to be further investigated. Here, we analyzed the influence of gender, parenthood and race on academic productivity during the pandemic period based on a survey answered by (...) 3,345 Brazilian academics from various knowledge areas and research institutions. Productivity was assessed by the ability to submit papers as planned and to meet deadlines during the initial period of social isolation in Brazil. The findings revealed that male academics – especially those without children – are the least affected group, whereas Black women and mothers are the most impacted groups. These impacts are likely a consequence of the well-known unequal division of domestic labor between men and women, which has been exacerbated during the pandemic. Additionally, our results highlight that racism strongly persists in academia, especially against Black women. The pandemic will have long-term effects on the career progression of the most affected groups. The results presented here are crucial for the development of actions and policies that aim to avoid further deepening the gender gap in academia. (shrink)

Boarding school is a major educational option for many students (e.g., students living in remote areas, or whose parents are working interstate or overseas, etc.). This study explored the motivation, engagement, and achievement of boarding and day students who are educated in the same classrooms and receive the same syllabus and instruction from the same teachers (thus a powerful research design to enable unique comparisons). Among 2,803 students (boardingn= 481; dayn= 2,322) from 6 Australian high schools and controlling for background (...) attributes and personality, we found predominant parity between boarding and day students in their motivation, engagement, and achievement. We also found that classroom-average motivation, engagement, and achievement was not significantly affected by the number of boarders (relative to day students) in the classroom. In addition, the effects of boarding were generally not moderated by students’ background or personality attributes. We conclude that boarders have academic opportunities and outcomes that are comparable to their day student counterparts. Implications for students, teachers, and parents are discussed. (shrink)

This study aims to find out the factors that hinder students in learning Integrated Art Education. A descriptive research design was utilized in the conduct of the study. The researcher prepared a questionnaire with 15 closed-ended- questions that could be answered objectively. The study discovered that the students would learn more when they feel that they belong to a certain group. Interests in a subject also matter, the more you are interested in a particular subject, the more you will learn (...) the material. Parent support marks an impact on the student's interest in learning Arts. Therefore, personal interest in a subject must be given attention and managed properly. Parent's support also plays a vital role in reinforcing the students on what to pursue in order to maintain their motivation. (shrink)

Research Ethics, Volume 18, Issue 1, Page 64-83, January 2022. Automated, wearable cameras can benefit health-related research by capturing accurate and objective information about individuals’ daily experiences. However, wearable cameras present unique privacy- and confidentiality-related risks due to the possibility of the images capturing identifying or sensitive information from participants and third parties. Although best practice guidelines for ethical research with wearable cameras have been published, limited information exists on the risks of studies using wearable cameras. The aim of this (...) literature review was to survey risks related to using wearable cameras, and precautions taken to reduce those risks, as reported in empirical research. Forty-five publications, comprising 36 independent studies, were reviewed, and findings revealed that participants’ primary concerns with using wearable cameras included physical inconvenience and discomfort in certain situations. None of the studies reviewed reported any serious adverse events. Although it is possible that reported findings do not include all risks experienced by participants in research with wearable cameras, our findings suggest a low level of risk to participants. However, it is important that investigators adopt recommended precautions, which can promote autonomy and reduce risks, including participant discomfort. (shrink)

Research in the U.S. developed and validated the State Self-Compassion Scale, which measures self-compassionate reactions toward a specific negative event. The current study is aimed at developing the Japanese version of the State Self-Compassion Scale and extending previous findings in the U.S. by showing measurement invariance across sexes and demonstrating the construct validity of this scale. Across two studies, the bifactor exploratory structural equation modeling representation of the SSCS-J showed excellent fit in which a single global factor and most of (...) the specific factors were well defined. Study 1 further provided evidence for the measurement invariance across sexes. The SSCS-J was related with higher trait self-compassion and lower fear of and negative beliefs about self-compassion. In Study 2, participants who were instructed to be self-compassionate reported higher scores in the SSCS-J relative to those in the control condition. These results attest to the replicability of the factor structure of the SSCS in Japan and provide further evidence for the construct validity of this scale. (shrink)

Multitasking is a critical feature of our daily lives. Using a dual-task paradigm, this experiment explored adults’ abilities to simultaneously engage in everyday motor and cognitive activities, counting while walking, under conditions varying the difficulty of each of these tasks. Motor difficulty was manipulated by having participants walk forward versus backward, and cognitive difficulty was manipulated by having participants count forward versus backward, employing either a serial 2 s or serial 3 s task. All of these manipulations were performed in (...) single-task conditions and dual-task conditions. Both motor performance variables and cognitive variables were assessed in these conditions. Analyses of single-task conditions revealed that both motor and cognitive manipulations predictably influenced performance. Analyses of dual-task performance revealed influences of motor and cognitive factors on both motor and cognitive performance. Most centrally, dual-task costs for motor variables revealed that such costs occurred primarily for temporal or spatiotemporal gait parameters and were driven by cognitive manipulations. Dual-task cost analyses for cognitive measures revealed negative dual-task costs, or dual-task benefits, for cognitive performance. Finally, the effects of dual-task manipulations were correlated for motor and cognitive measures, indicating dual-task performance as a significant individual difference variable. These findings are discussed with reference to theories of attentional allocation, as well as the possible role of auditory–motor entrainment in dual-task conditions. (shrink)

ABSTRACT This study examined how lifestyle factors and gender affect kidney allocation to transplant patients by 99 British and Singaporean participants. Thirty hypothetical patients were generated from a combination of six factors and randomly paired four times. Participants saw 60 patient pairings and, in each pair, chose which patient would receive treatment priority. A Bradley-Terry model was used to derive coefficients for each factor per participant. A mean factor score was then calculated across all participants for each factor. Participants gave (...) lower priority to patients who drank more, were overweight, smoked more and exercised less. A patient’s diet and gender had no significant effect on allocation. There were no significant cross-cultural differences. There were moderate correlations between participants’ self-reported pre- and post-experiment ordering of decision criteria, and these measures and factor coefficients, suggesting a modest level of decision-making consistency. Between participants, moderate levels of concordance with respect to factor importance were observed for self-reported orderings of factors, and weaker agreement for model-derived coefficients. Very similar results were obtained for both British and Singaporean participants, and the implications of the findings are discussed. (shrink)

Coach observation studies conducted since the 1970s have sought to determine the quantity and quality of verbal feedback provided by coaches to their athletes. Relatively few studies, however, have sought to determine the knowledge and beliefs of coaches that underpin this provision of feedback. The purpose of the current study was to identify the beliefs and knowledge that elite team sport coaches hold about providing, receiving and evaluating feedback in their training and competition environments. Semi-structured interviews conducted with 8 coaches (...) were inductively analysed, revealing three broad themes: thinking and learning about feedback, providing feedback, and evaluating feedback. Findings revealed a detailed array of knowledge about feedback across a wide range of sub-topics. Coaches saw feedback as a tool to improve performance, build athlete confidence, help athletes to monitor progress, and as a tool to improve their own performance. Novel insights about evaluating an athlete’s reception of feedback, and tailoring feedback for individual athletes, were provided by coaches. The findings also highlight areas in which future coach education offerings can better support coaches to provide effective feedback. (shrink)

The COVID-19 pandemic has necessitated innovations in data collection protocols, including use of virtual or remote visits. Although developmental scientists used virtual visits prior to COVID-19, validation of virtual assessments of infant socioemotional and language development are lacking. We aimed to fill this gap by validating a virtual visit protocol that assesses mother and infant behavior during the Still Face Paradigm and infant receptive and expressive communication using the Bayley-III Screening Test. Validation was accomplished through comparisons of data collected during (...) in-person laboratory visits and virtual visits conducted via Zoom. Of the 119 mother-infant dyads who participated, 73 participated in lab visits only, 13 participated in virtual visits only, and 33 dyads participated in a combination of lab and virtual visits across four time points. Maternal perspectives of, and preferences for, virtual visits were also assessed. Proportions of missing data were higher during virtual visits, particularly for assessments of infant receptive communication. Nonetheless, comparisons of virtual and laboratory visits within a given time point indicated that mothers and infants showed similar proportions of facial expressions, vocalizations and directions of gaze during the SFP and infants showed similar and expected patterns of behavioral change across SFP episodes. Infants also demonstrated comparable expressive and receptive communicative abilities across virtual and laboratory assessments. Maternal reports of ease and preference for virtual visits varied by infant age, with mothers of 12-month-old infants reporting, on average, less ease of virtual visits and a preference for in-person visits. Results are discussed in terms of feasibility and validity of virtual visits for assessing infant socioemotional and language development, and broader advantages and disadvantages of virtual visits are also considered.

It is widely recognized that police performance may be hindered by psychophysiological state changes during acute stress. To address the need for awareness and control of these physiological changes, police academies in many countries have implemented Heart-Rate Variability biofeedback training. Despite these trainings now being widely delivered in classroom setups, they typically lack the arousing action context needed for successful transfer to the operational field, where officers must apply learned skills, particularly when stress levels rise. The study presented here aimed (...) to address this gap by training physiological control skills in an arousing decision-making context. We developed a Virtual-Reality breathing-based biofeedback training in which police officers perform deep and slow diaphragmatic breathing in an engaging game-like action context. This VR game consisted of a selective shoot/don’t shoot game designed to assess response inhibition, an impaired capacity in high arousal situations. Biofeedback was provided based on adherence to a slow breathing pace: the slower and deeper the breathing, the less constrained peripheral vision became, facilitating accurate responses to the in-game demands. A total of nine male police trainers completed 10 sessions over a 4-week period as part of a single-case experimental ABAB study-design. Results showed that eight out of nine participants showed improved breathing control in action, with a positive effect on breathing-induced low frequency HRV, while also improving their in-game behavioral performance. Critically, the breathing-based skill learning transferred to subsequent sessions in which biofeedback was not presented. Importantly, all participants remained highly engaged throughout the training. Altogether, our study showed that our VR environment can be used to train breathing regulation in an arousing and active decision-making context. (shrink)
