We explore physiological linkage among 34 same-sex male couples. Interbeat interval, an indicator of cardiovascular arousal, was collected across four conversational contexts in the lab: a baseline period that did not involve conversation, a conversation about body image, a conversation about health goals, and a recovery period that allowed for unstructured conversation. We used a newly developed R statistical package that simplifies the use of dynamic models for investigating interpersonal emotional processes. We identified two different PL patterns: a simple one (...) that was characterized by stable synchronization and low frequency of oscillation; and a complex one that was characterized by drifting synchronization, high frequency of oscillation, and eventual damping. Guided by social baseline theory and the reactive flexibility perspective, we explored the interactions between couple relationship functioning and conversational context as predictors of the PL patterns. The results suggest that partners in well-functioning relationships and emotionally challenging situations may be especially likely to show complex PL patterns that may reflect coregulatory processes.

BackgroundCountries are increasingly devoting significant resources to creating or strengthening research ethics committees, but there has been insufficient attention to assessing whether these committees are actually improving the protection of human research participants.DiscussionResearch ethics committees face numerous obstacles to achieving their goal of improving research participant protection. These include the inherently amorphous nature of ethics review, the tendency of regulatory systems to encourage a focus on form over substance, financial and resource constraints, and conflicts of interest. Auditing and accreditation programs (...) can improve the quality of ethics review by encouraging the development of standardized policies and procedures, promoting a common base of knowledge, and enhancing the status of research ethics committees within their own institutions. However, these mechanisms focus largely on questions of structure and process and are therefore incapable of answering many critical questions about ethics committees' actual impact on research practices.The first step in determining whether research ethics committees are achieving their intended function is to identify what prospective research participants and their communities hope to get out of the ethics review process. Answers to this question can help guide the development of effective outcomes assessment measures. It is also important to determine whether research ethics committees' guidance to investigators is actually being followed. Finally, the information developed through outcomes assessment must be disseminated to key decision-makers and incorporated into practice. This article offers concrete suggestions for achieving these goals.ConclusionOutcomes assessment of research ethics committees should address the following questions: First, does research ethics committee review improve participants' understanding of the risks and potential benefits of studies? Second, does the process affect prospective participants' decisions about whether to participate in research? Third, does it change participants' subjective experiences in studies or their attitudes about research? Fourth, does it reduce the riskiness of research? Fifth, does it result in more research responsive to the local community's self-identified needs? Sixth, is research ethics committees' guidance to researchers actually being followed? (shrink)

COVID-19 caused levels of household food insecurity to spike, but the precarity of so many people in wealthy countries is an outgrowth of decades of eroding public provisions and labour protections that once protected people from hunger, setting the stage for the virus’ unevenly-distributed harms. The prominence of corporate-sponsored foodbanking as a containment response to pandemic-aggravated food insecurity follows decades of replacing rights with charity. We review structural drivers of charity’s growth to prominence as a hunger solution in North America, (...) and of its spread to countries including the UK. By highlighting pre-pandemic pressures shaping foodbanking, including charities’ efforts to retool themselves as health providers, we ask whether anti-hunger efforts during the pandemic serve to contain ongoing socioeconomic crises and the unjust living conditions they cause, or contest them through transformative pathways to a just food system. We suggest that pandemic-driven philanthropic and state funding flows have bolstered foodbanking and the food system logics that support it. By contextualising the complex and variegated politics of foodbanking in broader movements, from community food security to food sovereignty, we reframe simplistic narratives of charity and highlight the need for justice-oriented structural changes in wealth redistribution and food system organisation if we are to prevent the kinds of emergency-within-emergency that we witnessed as COVID-19 revealed the proximity of many to hunger.

BackgroundSexual boundary violations in healthcare are harmful and exploitative sexual transgressions in the professional–client relationship. Persons with mental health issues or intellectual disabilities, especially those living in residential settings, are especially vulnerable to SBV because they often receive long-term intimate care. Promoting good sexual health and preventing SBV in these care contexts is a moral and practical challenge for healthcare organizations.MethodsWe carried out a qualitative interview study with 16 Dutch policy advisors, regulators, healthcare professionals and other relevant experts to explore (...) their perspectives on preventing SBV in mental health and disability care organizations. We used inductive thematic analysis to interpret our data.ResultsWe found three main themes on how healthcare organizations can prevent SBV in mental health and disability care: setting rules and regulations, engaging in dialogue about sexuality, and addressing systemic and organizational dimensions.ConclusionOur findings suggest that preventing SBV in mental health and disability care organizations necessitates setting suitable rules and regulations and facilitating dialogue about positive aspects of sexuality and intimacy, as well as about boundaries, and inappropriate behaviors or feelings. Combining both further requires organizational policies and practices that promote transparency and reflection, and focus on creating a safe environment. Our findings will help prevent SBV and promote sexual health in mental health and disability care organizations. (shrink)

This article reflects on the contribution that stakeholder involvement could give to circular bioeconomy transformation (CBE). By comparing argument for stakeholder involvement in literature as well as on our own experiences in six stakeholder involvement workshops, we argue that it is probably unrealistic to fully achieve both normative and co-design goals in a single workshop. Furthermore, stakeholder involvement can help to acquire insight into dependencies in the market and offer an opportunity to connect people to deal with them. Therefore we (...) propose for future stakeholder involvement initiatives for CBE to focus on (1) identify relationships of dependency which make it hard for players in the market to change, (2) develop strategies to change while mitigating the detrimental effects on already existing relationships and (3) gradually breaking down relationships and building new ones that support CBE.

The inconsistency between pro-environmental attitudes and behaviours, known as the “attitude-behaviour” gap, is exceptionally pronounced in scenarios associated with “green” choice. The current literature offers numerous explanations for the reasons behind the “attitude-behaviour” gap, however, the generalisability of these explanations is complex. In addition, the answer to the question of whether the gap occurs between attitudes and intentions, or intentions and behaviours is also unknown. In this study, we propose the moral dimension as a generalisable driver of the “attitude-behaviour” gap (...) and investigate its effectiveness in predicting attitudes, pro-environmental intentions and subsequent behaviours. We do so by using Hunt–Vitell’s moral philosophy-based framework of ethical decision-making, which conceptualises morality as the central decision-making parameter. The results from 557 US MTurk participants revealed that the manipulation of moral dimensions, specifically deontology and teleology, impacted ethical evaluation of presented dilemmas, however, failed to translate into subsequent intentions and behaviours. This finding suggests (i) that the moral dimension has an effect in shaping attitudes toward environmental issues, and (ii) that gap occurs between attitudes and intentions rather than intentions and behaviours. Further investigation of what strengthens and/or overrides the effects of the moral dimension would help understand the reasons why moral attitudes do not always translate into subsequent intentions and behaviours in the pro-environmental domain.

This book presents a series of informal biographies about major figures in the history of psychology. A unique combination of expertise and human appeal, the volume places the contributions of each pioneer in a new and fascinating perspective. For instance, several of the authors use the novel approach of having the pioneers return to the present day to reflect back on their work as it relates to the here and now. Revisions of speeches given in a popular series of invited (...) addresses at psychological conventions, the chapters offer appealing glimpses into the lives of individuals who made a difference in the early years of psychology as a field of study. Each of the five volumes in this series contains different profiles thereby bringing more than 100 of the pioneers in psychology more vividly to life. (shrink)

Researchers from diverse disciplines, including organismal and cellular physiology, sports science, human nutrition, evolution and ecology, have sought to understand the causes and consequences of the surprising variation in metabolic rate found among and within individual animals of the same species. Research in this area has been hampered by differences in approach, terminology and methodology, and the context in which measurements are made. Recent advances provide important opportunities to identify and address the key questions in the field. By bringing together (...) researchers from different areas of biology and biomedicine, we describe and evaluate these developments and the insights they could yield, highlighting the need for more standardisation across disciplines. We conclude with a list of important questions that can now be addressed by developing a common conceptual and methodological toolkit for studies on metabolic variation in animals. (shrink)

Background The first COVID-19 wave started in February 2020 in France. The influx of patients requiring emergency care and high-level technicity led healthcare professionals to fear saturation of available care. In that context, the multidisciplinary Ethics- Support Cell (EST) was created to help medical teams consider the decisions that could potentially be sources of ethical dilemmas. Objectives The primary objective was to prospectively collect information on requests for EST assistance from 23 March to 9 May 2020. The secondary aim was (...) to describe the Cell’s functions during that period. Research design This observational, real-time study of requests for Cell consultations concerned ethical dilemmas arising during a public health crisis. The EST created a grid to collect relevant information (clinical, patient’s/designated representative’s preferences and ethical principles strained by the situation), thereby assuring that each EST asked the same questions, in the same order. Participants and research context Only our university hospital’s clinicians could request EST intervention. Ethical considerations The hospital Research Ethics Committee approved this study (no. CER-2020-107). The patient, his/her family, or designated representative was informed of this ethics consultation and most met with EST members, which enabled them to express their preferences and/or opposition. Findings/results 33 requests (patients’ mean age: 80.8 years; 29 had COVID-19: 24 with dyspnea, 30 with comorbidities). 17 Emergency Department solicitations concerned ICU admission, without reference to resource constraints; others addressed therapeutic proportionality dilemmas. Discussion Intervention-request motives concerned limited resources and treatment intensity. Management revolved around three axes: the treatment option most appropriate for the patient, the feasibility of implementation, and dignified care for the patient. Conclusions COVID-19 crisis forced hospitals to envisage prioritization of ICU access. Established decision-making criteria and protocols do not enable healthcare professionals to escape ethical dilemmas. That acknowledgement highlights ethical risks, enhances the added-value of nursing and encourages all players to be vigilant to pursue collective deliberations to achieve clear and transparent decisions.

BackgroundInstrumented gait analysis post-stroke is becoming increasingly more common in research and clinics. Although overall standardized procedures are proposed, an almost infinite number of potential variables for kinematic analysis is generated and there remains a lack of consensus regarding which are the most important for sufficient evaluation. The current aim was to identify a discriminative core set of kinematic variables for gait post-stroke.MethodsWe applied a three-step process of statistical analysis on commonly used kinematic gait variables comprising the whole body, derived (...) from 3D motion data on 31 persons post-stroke and 41 non-disabled controls. The process of identifying relevant core sets involved: exclusion of variables for which there were no significant group differences; systematic investigation of one, or combinations of either two, three, or four significant variables whereby each core set was evaluated using a leave-one-out cross-validation combined with logistic regression to estimate a misclassification rate.ResultsThe best MR for one single variable was shown for the Duration of single-support or Duration of 2nd double-support phase, corresponding to an 89–90% probability of correctly classifying a person as post-stroke/control. Adding Pelvis sagittal ROM to either of the variables Self-selected gait speed or Stride length, alternatively adding Ankle sagittal ROM to the Duration of single-stance phase, increased the probability of correctly classifying individuals to 93–94%. Combining three variables decreased the MR further to 0.04, suggesting a probability of 96% for correct classification. These core sets contained: a spatial or a temporal variable, Pelvis sagittal ROM or Ankle plantarflexion during push-off, and Arm Posture Score or Cadence or a knee/shoulder joint angle variable. Adding a fourth variable did not further improve the MR.ConclusionA core set combining a few crucial kinematic variables may sufficiently evaluate post-stroke gait and should receive more attention in rehabilitation. Our results may contribute toward a consensus on gait evaluation post-stroke, which could substantially facilitate future diagnosis and monitoring of rehabilitation progress. (shrink)

Knee proprioception deficits and neuroplasticity have been indicated following injury to the anterior cruciate ligament. Evidence is, however, scarce regarding brain response to knee proprioception tasks and the impact of ACL injury. This study aimed to identify brain regions associated with the proprioceptive sense of joint position at the knee and whether the related brain response of individuals with ACL reconstruction differed from that of asymptomatic controls. Twenty-one persons with unilateral ACL reconstruction of either the right or left knee, as (...) well as 19 controls matched for sex, age, height, weight and current activity level, performed a knee joint position sense test during simultaneous functional magnetic resonance imaging. Integrated motion capture provided real-time knee kinematics to activate test instructions, as well as accurate knee angles for JPS outcomes. Recruited brain regions during knee angle reproduction included somatosensory cortices, prefrontal cortex and insula. Neither brain response nor JPS errors differed between groups, but across groups significant correlations revealed that greater errors were associated with greater ipsilateral response in the anterior cingulate, supramarginal gyrus and insula. This is the first study to capture brain response using fMRI in relation to quantifiable knee JPS. Activated brain regions have previously been associated with sensorimotor processes, body schema and interoception. Our innovative paradigm can help to guide future research investigating brain response to lower limb proprioception. (shrink)

Who is a native signer? Since around 95% of deaf infants are born into a hearing family, deaf signers are exposed to a sign language at various moments of their life, and not only from birth. Moreover, the linguistic input they are exposed to is not always a fully fledged natural sign language. In this situation, is the notion of native signer as someone exposed to language from birth of any use? We review the results of the first large-scale cross-linguistic (...) investigation on the effects of age of exposure to sign language. This research involved about 45 Deaf adult signers in each of three sign languages (Catalan Sign Language, French Sign Language, and Italian Sign Language). Across the three languages, participants were divided into three groups – those exposed from birth, those between 1 and 5 years of age, and those exposed between 6 and 15 years of age – and received a battery of tests designed for each language targeting various aspects of morphosyntactic competence. In particular, the tests focused on both those morphosyntactic phenomena that are known from the spoken language literature to be good detectors of language impairment or delay (i.e.,wh-interrogatives and relative clauses) and on morphosyntactic phenomena that are sign language specific (i.e., role shift and directional verbs). The results showed a clear effect of being native, with significant differences across languages and tests between signers exposed to sign language from birth and those exposed in the 1st years of life. This confirms the life-long importance of language exposure from birth and the reliability of the notion of “nativeness”, at least for syntax. On the other hand, while in most domains the differences observed between populations might be differences in performance, for some specific constructions, signers belonging to the three groups may have different grammars. This latter finding challenges the generalized use of native signers’ grammar as the baseline for language description and language assessment. (shrink)

Medical educators recognize the value of reflection for medical students and the role creative writing can play in fostering this. However, direct creative writing tasks can be challenging for many students, particularly those with limited experience in the arts and humanities. An alternative strategy is to utilize an indirect approach, engaging students with structured tasks that obliquely encourage reflection. This paper reports one such approach. We refer to this approach as in-verse reflection, playing on both the structure of the writing (...) and its novel approach to reflection. Students were invited to write, in verse-like structures, about their personal and clinical experiences as medical students. Thematic analysis of their creative outputs and reactions identified four principal themes: the challenges of life as a medical student, the emotional demands of the medical course, a sense of connectedness and solidarity with fellow students, and a sense of marginality within the hospital system. Students generally found the tasks highly engaging and conducive to reflection, producing texts representing significant insights into their experiences as medical students. The reported method offers a relatively simple, structured, and guided approach to reflective writing, adding to the repertoire of methods available to educators in the medical humanities. (shrink)

The provision of informed consent is a prerequisite for inclusion of a patient in a clinical research project. In some countries, the legislation on clinical research authorizes a third person to provide informed consent if the patient is unable to do so directly . This is the case during acute stroke, when the symptoms may prevent the patient from providing informed consent and thus require a third party to be approached. Identification of factors associated with the medical team’s decision to (...) resort to surrogate consent may help the care team during the inclusion process and enable the patient’s family circle to be better informed about providing surrogate consent.

This article discusses how existential phenomenology may serve as a frame in a mixed‐methods study of changes in weight and body composition among women in adjuvant treatment for breast cancer. In accordance with ontologically and epistemologically fundamental assumptions in nursing, we link mixed‐methods and existential phenomenology from the perspective of the French philosopher Maurice Merleau‐Ponty and his notion of a unified body subject. Letting this perspective permeate our philosophy, methodology and issues at the method level in mixed‐method research undermines the (...) distinction between first‐ and third‐person perspective when applying and integrating different data sources in a mixed‐methods study. Applying Merleau‐Ponty's third way, the women's bodily experiences appear as gestalt; a ‘figure’ against a ground of existential threats that are grasped through insight from data integrating in joint displays, which revealed the women's experiences on a deep existential level. Existential phenomenology as a frame in mixed‐method studies can speak not only to nurses but also to a multidisciplinary audience in a shared attempt to deepen the understanding of a patient's healthcare problem.

In a series of recently published lectures and essays two Roman Catholic Cardinals—Cardinals Ratzinger and Kasper—have offered significantly different positions of the issue of the relationship of the Universal to the Particular Churches. Cardinal Kasper locates the root of the disagreement in the philosophical foundations of the two views in privileging the Universal over the Particular (or vice versa) as the starting point for ecclesiology. I will explain why I find Josiah Royce’s late work (as informed by C. S. Peirce’s (...) thought) to be a valuable resource for the complexities of such a rich ecclesiological enquiry. I examine the interrelationship between Spirit, Community and the Interpretation of Signs in the mature thought of Royce, I assess his contribution to the preceding discussion, and I offer some insights into his potential value to any ongoing dialogue on the nature and purpose of the Church.

The importance of developing cultural competence among healthcare professionals is well recognized. However, the widespread reports of insensitivity and deficiencies in care for culturally diverse patients illuminate the need to review how cultural competence development is taught, learnt and applied in practice. Unless we can alter the ‘hearts and minds’ of practising nurses to provide the care that they know they should, culturally insensitive care will continue operating in subtle ways. This paper explores the ideas behind nurses’ actions and omissions (...) when caring for culturally diverse patients and proposes the need to examine cultural competence development through a moral reasoning lens. Examining cultural competence development through a moral reasoning lens can help empower nurses, whilst nurturing commitment and courage to providing quality care that meets the needs of culturally diverse patients. The model of morality provides a framework that explores how moral motivation and behaviour occur and can provide a vehicle for critically examining the knowledge, skills and attitudes required to provide culturally responsive care.

Charlotte Wolff was born in Riesenburg, West Prussia into a middle-class Jewish family. She studied philosophy and then medicine at several German universities, completing her doctorate in Berlin in 1926. Working in various institutions over the next few years, she was also interested in psychotherapy and had a small private medical and psychotherapeutic practice. In 1933 she was forced to leave Germany because of the Nazi regime, and settled for a few years in Paris. As a German refugee she (...) was unable to practice medicine, so she began her research into the correlation between hand traits and personality. In 1936 she went to London to continue her research work and lived there until her death. An active lesbian from an early age, her later research turned to sexology and her writing on lesbianism and bisexuality were influential early works in the field. This is a great opportunity to rediscover her early work, including her first autobiography. (shrink)

ABSTRACT:This paper explores how corporations, through their Corporate Social Responsibility (CSR) activities, can help to effect positive developmental change. We use research on institutional change, deinstitutionalization, and institutional work to develop our central theoretical framework. This framework allows us to suggest more explicitly how CSR can potentially be mobilized as a purposive form of institutional work aimed at disrupting existing institutions in favor of positive change. We take the gender institution in the Arab Middle East as a case in point. (...) Our suggestion is that the current context of the Arab Spring, which combined with increasingly obvious endogenous institutional contradictions, has created a fertile ground for shaping change processes within the gender institution. Finally, we provide concrete examples of CSR initiatives that regional corporate actors can engage in for positive developmental change supporting women. (shrink)

In the current paper, our aim is to explore the latent power dynamics surrounding corporate social responsibility in developing countries. To do this, we synthesize an analytic framework that borrows from both cross-cultural management literature as well as feminist considerations of power. We then use the framework to examine three streams of CSR literature. Our analysis uncovers the prevalence of arguments and discussions about indigenous and power-over themes rather than more generative, endogenous, and power-to themes. The paper concludes with the (...) suggestion for more space in the CSR literature for examining the realities and potentialities of local SME CSR expressions to counterbalance the overwhelming focus on MNCs. Such counterbalancing can better lead to the recognition that power and domination are not the only important dynamics to examine in CSR research. Just as important is the need for a more nuanced consideration of the role and contributions of different actors to the continuously unfolding CSR discourse. (shrink)

This was the last and most important and comprehensive work of Charlotte Mason, (founder of the Parents’ National Educational Union).

We are all immersed in a sea of social norms, but they are sometimes tricky to observe with any clarity. They are often invisible to us and emerge only when they are not observed. Social norms are important to understand because they are both limiting of our freedom, such as gendered and racialized norms, and at the same time the very conditions of our agency. Social Goodness presents an original, externalist answer to the question of the source or origin of (...) social role normativity. Rather than grounding social normativity in the attitudes of persons, the book argues for an externalism that roots social role normativity in the social world itself: in its positions, institutions, and larger architecture. The core insight of externalism is that the function or structural feature of an enterprise or activity can bring with it normative demands quite independently of the attitudes of those who engage with it. According to the artisanal model, just as a carpenter, ceramicist, or chef is responsive to and evaluable under a set of artisanal norms or techniques, so too is a mother and or an academic or a President. The source of normativity is this technique or expertise, independent of the preferences, endorsements, or recognitive attitudes of individuals. The artisanal model for social role normativity has resources to explain both the "stickiness" or persistence of social norms and our ability to criticize existing norms and to engage in normative self-creation--to create new normative selves. The artisanal model also has resources to capture and express the social situatedness, locality, and materiality of social roles. The relational ontology of social roles, implicit in the artisanal model, provides a useful frame to consider both hierarchical and oppressive social relations. (shrink)

In a criminal trial, evidence is used to draw conclusions about what happened concerning a supposed crime. Traditionally, the three main approaches to modeling reasoning with evidence are argumentative, narrative and probabilistic approaches. Integrating these three approaches could arguably enhance the communication between an expert and a judge or jury. In previous work, techniques were proposed to represent narratives in a Bayesian network and to use narratives as a basis for systematizing the construction of a Bayesian network for a legal (...) case. In this paper, these techniques are combined to form a design method for constructing a Bayesian network based on narratives. This design method is evaluated by means of an extensive case study concerning the notorious Dutch case of the Anjum murders. (shrink)

This study focuses on how moral aspects of purpose shape collaborative processes. It does so by analyzing the unfolding of 21 relationships between four nonprofits and their funders using a framework based on French pragmatist sociology to help uncover the deeply held, ideological and moral beliefs that underscore assumptions about what the overarching purpose of a collaborative effort is or should be. This study contributes to the literature on single and cross-sectoral collaboration by showing that the way partners handle and (...) reconcile differences about purpose is related to the forms of agreement likely to be achieved. It also suggests that certain forms of agreement are inherently more enduring than others. Taken as a whole, this study provides some plausible explanations as to why so many collaborations fail despite their seeming benefits for all the parties involved. (shrink)

The global development of human embryonic stem cell science and its therapeutic applications are dependent on the nature of its engagement at national and international levels with key cultural values and beliefs concerning the moral status of the early human embryo. This article argues that the political need to reconcile the promise of new health technologies with the cultural costs of scientific advance, dependent in this case on the use of the human embryo, has been met by the evolution of (...) bioethics as a political community, transnational network, and bureaucratic device. Bioethics has become the political means for the creation of a global moral economy where the trading and exchange of values is normalized and legitimated. As a result of such trading, value compromises are produced capable of legitimizing the regulatory policies necessary for maintaining public trust in the new science. (shrink)

This paper addresses the actual practice of justifying definitions in mathematics. First, I introduce the main account of this issue, namely Lakatos's proof-generated definitions. Based on a case study of definitions of randomness in ergodic theory, I identify three other common ways of justifying definitions: natural-world justification, condition justification, and redundancy justification. Also, I clarify the interrelationships between the different kinds of justification. Finally, I point out how Lakatos's ideas are limited: they fail to show how various kinds of justification (...) can be found and can be reasonable, and they fail to acknowledge the interplay among the different kinds of justification.

Many examples of calibration in climate science raise no alarms regarding model reliability. We examine one example and show that, in employing Classical Hypothesis-testing, it involves calibrating a base model against data that is also used to confirm the model. This is counter to the "intuitive position". We argue, however, that aspects of the intuitive position are upheld by some methods, in particular, the general Cross-validation method. How Cross-validation relates to other prominent Classical methods such as the Akaike Information Criterion (...) and Bayesian Information Criterion is also discussed. (shrink)
