Beginning in the mid-1930s the comparative physiologists Laurence Irving and Per Fredrik Scholander pioneered the study of diving mammals, particularly harbor seals. Although resting on earlier work dating back to the late nineteenth century, their research was distinctive in several ways. In contrast to medically oriented physiology, the approaches of Irving and Scholander were strongly influenced by natural history, zoology, ecology, and evolutionary biology. Diving mammals, they argued, shared the cardiopulmonary physiology of terrestrial mammals, but evolution had modified these basic (...) adaptive processes in extreme ways. In particular, seals’ remarkable ability to hold breath, lower metabolism, produce energy anaerobically, and resist asphyxiation, provided a sharp contrast with terrestrial mammals, including humans. This diving physiology was an extreme elaboration of a general regulatory mechanism that allowed seals and other diving mammals to remain active underwater for extended periods. The decrease in heart rate referred to as bradycardia or the “diving reflex” was highly developed in diving mammals, but also found in less developed form in many other organisms faced by asphyxia. It therefore served as a kind of “master switch” for lowering metabolism in diving, hibernation, parturition, drowning, and other physiological responses involving lack of oxygen. Studying bradycardia unified a wide diversity of physiological phenomena, while also providing a context for contrasting the physiological responses of various species, including humans. Conducted in the laboratory and the field, this research served as a bridge between a comparative physiological ecology focused on non-human species and a human-centered general physiology. (shrink)

Harry G. Frankfurt begins his inquiry by asking, “What is it about human beings that makes it possible for us to take ourselves seriously?” Based on The Tanner Lectures in Moral Philosophy, Taking Ourselves Seriously and Getting It Right delves into this provocative and original question. The author maintains that taking ourselves seriously presupposes an inward-directed, reflexive oversight that enables us to focus our attention directly upon ourselves, and “[it] means that we are not prepared to accept ourselves just as (...) we come. We want our thoughts, our feelings, our choices, and our behavior to make sense. We are not satisfied to think that our ideas are formed haphazardly, or that our actions are driven by transient and opaque impulses or by mindless decisions. We need to direct ourselves—or at any rate to believe that we are directing ourselves—in thoughtful conformity to stable and appropriate norms. We want to get things right.” The essays delineate two features that have a critical role to play in this: our rationality, and our ability to love. Frankfurt incisively explores the roles of reason and of love in our active lives, and considers the relation between these two motivating forces of our actions. The argument is that the authority of practical reason is less fundamental than the authority of love. Love, as the author defines it, is a volitional matter, that is, it consists in what we are actually committed to caring about. Frankfurt adds that “The object of love can be almost anything—a life, a quality of experience, a person, a group, a moral ideal, a nonmoral ideal, a tradition, whatever.” However, these objects and ideals are difficult to comprehend and often in conflict with each other. Moral principles play an important supporting role in this process as they help us develop and elucidate a vision that inspires our love. The first section of the book consists of the two lectures, which are entitled “Taking Ourselves Seriously” and “Getting It Right.” The second section consists of comments in response by Christine M. Korsgaard, Michael E. Bratman, and Meir Dan-Cohen. The book includes a preface by Debra Satz. (shrink)

Ethics support services like Moral Case Deliberation intend to support healthcare professionals in ethically difficult situations. To assess outcomes of MCD, the Euro-MCD Instrument has been developed. Field studies to test this instrument are needed and have been conducted, examining important outcomes before MCD participation and experienced outcomes. The current study aimed to describe how participants’ perceive the importance of MCD outcomes after MCD; compare these perceptions with those before MCD participation; and test the factor structure of these outcomes. Swedish, (...) Norwegian and Dutch healthcare professionals rated the importance of outcomes in the Euro-MCD Instrument after four and eight MCDs. Ratings were compared with those before MCD participation using paired and independent samples t-tests. The factor structure was tested using exploratory factor analyses. After 4 and 8 MCDs, 443 respectively 247 respondents completed the instrument. More than 69% rated all MCD outcomes as ‘quite’ or ‘very’ important, especially outcomes from Enhanced Collaboration, Improved Moral Reflexivity and Improved Moral Attitude. Significant differences for 16 outcomes regarding ratings before and after MCD participation were not considered meaningful. Factor analyses suggested three categories, which seemingly resemble the domains Improved Moral Reflexivity, Enhanced Collaboration and a combination of Improved Moral Attitude and Enhanced Emotional Support. After participation in MCDs, respondents confirmed the importance of outcomes in the Euro-MCD Instrument. The question on perceived importance and the categorization of outcomes need reconsideration. The revised instrument will be presented elsewhere, based on all field studies and theoretical reflections. (shrink)

Pulmonary ventilation and respiration are considered to be primarily involved in oxygenation of blood for oxygen delivery to cells throughout the body for metabolic purposes. Other pulmonary physiological observations, such as respiratory sinus arrhythmia, Hering Brewer reflex, cardiorespiratory synchronization, and the heart rate variability (HRV) relationship with breathing rhythm, lack complete explanations of physiological/functional significance. The spectrum of waveforms of breathing activity correlate to anxiety, depression, anger, stress, and other positive and negative emotions. Respiratory pattern has been thought (...) not only to be influenced by emotion but to itself influence emotion in a bi-directional relationship between the body and the mind. In order to show how filling in gaps in understanding could lead to certain future developments in mind–body medicine, biofeedback, and personal health monitoring, we review and discuss empirical work and tracings to express the vital role of bodily rhythms in influencing emotion, autonomic nervous system activity, and even general neural activity. Future developments in measurement and psychophysiological understanding of the pattern of breathing in combination with other parameters such as HRV, cardiorespiratory synchronization, and skin conductivity may allow for biometric monitoring systems to one day accurately predict affective state and even affective disorders such as anxiety. Better affective prediction based on recent research when incorporated into personal health monitoring devices could greatly improve public mental health by providing at-home biofeedback for greater understanding of one’s mental state and for mind–body affective treatments such as breathing exercises.

BackgroundExtremely violent events such as terrorist attacks and mass shootings form a severe risk for the health and wellbeing of affected individuals. In this study based on a public health monitor, we focus on the health impact of the Utrecht tram shooting, which took place in the morning of March 18th 2019. A lone gunman opened fire on passengers within a moving tram. Four people died, and six people were injured in this attack. The attack resulted in nationwide commotion and (...) drew much media attention. Aim of this study was to increase insight into the health effects for the survivors, and whether they received the needed care and support.MethodsSemi-structured interviews with accompanying questionnaires were conducted at six and 18 months post-attack. Overall, 21 survivors participated in the first series of interviews, 15 in the second series. Qualitative data were analyzed using reflexive thematic analysis, quantitative data was only described because of the low sample size.ResultsAt both six and 18 months after the attack many survivors had been able to resume daily life, and most rated their overall health as good or excellent. At the same time, a substantial portion suffered from health problems such as posttraumatic stress symptoms and other complaints, and needed professional care. Furthermore, those in need did not always find their own way to appropriate care through the existing health system: half of the survivors still needed support in finding the right care 18 months later.ConclusionAlthough the design and implementation of this public health monitor were accompanied by multiple challenges, it was possible to track a portion of the survivors and gain insight in the considerable health burden of the attack. Also, it is clear in this study that the health impact of terrorism affects survivors in the long run and requires attention from health authorities and professionals, as survivors were not able to find the right care by themselves.

We conducted two eye-tracking experiments investigating the processing of the Mandarin reflexive ziji in order to tease apart structurally constrained accounts from standard cue-based accounts of memory retrieval. In both experiments, we tested whether structurally inaccessible distractors that fulfill the animacy requirement of ziji influence processing times at the reflexive. In Experiment 1, we manipulated animacy of the antecedent and a structurally inaccessible distractor intervening between the antecedent and the reflexive. In conditions where the accessible antecedent mismatched the animacy cue, (...) we found inhibitory interference whereas in antecedent-match conditions, no effect of the distractor was observed. In Experiment 2, we tested only antecedent-match configurations and manipulated locality of the reflexive-antecedent binding (Mandarin allows non-local binding). Participants were asked to hold three distractors (animate vs. inanimate nouns) in memory while reading the target sentence. We found slower reading times when animate distractors were held in memory (inhibitory interference). Moreover, we replicated the locality effect reported in previous studies. These results are incompatible with structure-based accounts. However, the cue-based ACT-R model of Lewis and Vasishth ( 2005 ) cannot explain the observed pattern either. We therefore extend the original ACT-R model and show how this model not only explains the data presented in this article, but is also able to account for previously unexplained patterns in the literature on reflexive processing.

“Ethics in practice” are the ethical dilemmas that arise during the conduct of research. In this article, we describe the ethical issues we faced when conducting an exploration of the experiences of 19 potential living kidney donors, and demonstrate how reflexivity can guide the ethical decision-making throughout the research process. We discuss how we addressed issues of risk of potential psychological discomfort and distress to participants; autonomy and consent; and power imbalance, disclosure and reciprocity. We also address the practical implications (...) of our decisions. Through this discussion of the “ethically important” moments we faced, we aim to spark debate about the ethical and practical challenges facing qualitative health researchers today, and demonstrate how reflexivity can contribute to navigating the “ethical labyrinth” of qualitative health research.

Although much has been written about the centrality of reflexivity in qualitative research, the literature on researcher’s reflexivity in prison research is limited. I conducted a PhD qualitative study with a sample of 30 women convicted of murder from one female prison in Uganda. This paper demonstrates the value of reflexivity in research with respect to oppressed women. It does this by discussing what reflexivity is and at what stage of the research process reflexivity is deemed important. Most importantly, the (...) paper discusses different forms of reflexivity that I exercised, which include personal reflexivity, feminist reflexivity, emotional reflexivity, methodological reflexivity and reflexivity on research context and participants. The paper demonstrates how these different forms of reflexivity helped in various research aspects such as the evolution of the topic that empowered women to tell their stories in a context that was without any research on women convicted of murder, in recruitment of participants, avoiding harming participants and in dealing with emotion during data collection.

Most work on reflexivity has focused on individuals exercising their reflexivity through discourse. However, agents have three major aspects (intentionality, causal efficacy and embodiment) and they are fundamentally social. This article examines the possibility of collective reflexivity conducted not just by saying, but also by doing—that is, through their embodiment. By expanding the concept of ‘performatives’ to encompass not just speech acts but also acts that speak (i.e. embodied activities as socially meaningful) and applying the work of Charles S. Peirce (...) in order to develop an ontology of embodied reflexivity, it becomes possible to determine several criteria defining embodied collective reflexivity. Assessing possibilities such as legislative debate, political demonstrations, religious ritual and dramatic performance reveals that a certain set of practices does in fact meet those criteria and discloses additional aspects of what constitutes embodied collective reflexivity.

BackgroundResistance training (RT) can offer beneficial physiological and psychological effects. The regular continuation of this exercise can be accomplished by improving the recovery and mood after a workout. Frequency-specific microcurrent (microstimulation) might offer a solution here as it has been shown to improve physical injuries, mood state, and sleep. However, knowledge is lacking about the impact of microstimulation after RT on said parameters. The present study aimed to test the effects of RT and muscle-microstimulation on mood and physical recovery in (...) healthy men after performing conventional deadlifts, which is a type of RT.MethodsThe study was conducted according to a single-blind, randomized, placebo-controlled, and two-way crossover study. Twenty participants naïve to microstimulation (MS) engaged in RT twice on separate days. They were randomized to receive MS on 1 day and no microstimulation (Sham-MS) on another day. Before and after the workout and after their treatment (MS or Sham-MS), participants self-rated their mood state and mental and physical exhaustion levels.ResultsFindings showed that MS increased the self-ratings of well-rested and sociable and, most importantly, reduced the feeling of exercise-induced exhaustion. There were no MS effects on ratings of feeling sad, happy, or exhausted, although the workout, independent of MS, negatively influenced the level of exhaustion.ConclusionThe combination of enhanced sociableness, reduced fatigue, and exercise-induced exhaustion after a workout, followed by microstimulation, has important implications for professional sporters and nonprofessionals who try to get the best result after a workout. Future studies using a double-blind approach including different types of exercises, different durations of programs, and both sexes can shed more light on the full potential of microstimulation after a workout on mood state and exercise-induced exhaustion.

Simulation of brain dynamics requires the use of accurate empirical data. This commentary points out major errors in some of the empirical data used in Wright & Laley's simulation. The simulation is quantitatively very different from the real cortex, and may also have important qualitative differences.

Neoliberal educational reforms include extensive use of standardized tests. We examine the Program for International Student Assessment (PISA) initiated and developed by the Organization for Economic Cooperation and Development (OECD). Examining previous research on teachers’ reactions to neoliberal reforms altering their work context, we have identified three theoretical frameworks in use: labour process theory, derived from structural Marxism; post-structuralism, relying primarily on Foucault’s conceptualizations; and ‘new professionalism’, which has emerged from the theory of professions. A major weakness in these frameworks (...) is their inability to account for different reactions to the same structural and cultural conditions. Therefore, we suggest utilizing Archer’s theories of reflexivity and reflexive modes to understand these reactions. Presenting one Norwegian lower secondary school teacher’s reflexive engagement with PISA in the Norwegian school context as an example, our mixed methods case study indicates autonomous reflexivity as the prevailing mode. Meta-reflexivity rates second in prevalence. (shrink)

The Reflexive Imagery Task (RIT) reveals that the activation of sets can result in involuntary cognitions that are triggered by external stimuli. In the basic RIT, subjects are presented with an image of an object (e.g., CAT) and instructed to not think of the name of the object. Involuntary subvocalizations of the name (the RIT effect) arise on roughly 80% of the trials. We conducted an electroencephalography (EEG) study to explore the neural correlates of the RIT effect. Subjects were presented (...) with one object at a time in one condition and two objects simultaneously in another condition. Five regions were defined by electrode sites: frontal (F3–F4), parietal (P3–P4), temporal (T3–T4), right hemisphere (F4–P4), and left hemisphere (F3–P3). We focused on the alpha (8–13 Hz), beta (13–30 Hz), delta (0.01–4 Hz), and theta (4–8 Hz) frequencies. (shrink)

Abstract I will explicate Zhuangzi's conception of wuwei as it is articulated in the image of the ?hinge of dao.? First, I will discuss the few actual instances of the term ?wuwei? in the Zhuangzi. Second, I will show that the text uses this imagery to suggest an adaptive or reflective mode of conduct. Third, I will analyse the metaphor of the hinge, and show how this metaphor can illuminate Zhuangzi's notion of wuwei and the behaviour of the realised person. (...) I will show that the hinge represents the way in which the ideal person responds to inevitability, and that Zhuangzi's ideal person could be described as ?perfectly well?adjusted?. Finally, I will demonstrate that this reading offers new meanings and textures to a text that has long been read in only certain ways, so that many of its subtleties have been overlooked. (shrink)

Questions have been raised over the acceptability of conducting human challenge studies in low and middle income countries. Most of these concerns are based on theoretical considerations and there exists little data on the attitudes of stakeholders in these countries. This study examines the view of researchers and REC members in Thailand regarding the design and conduct of challenge studies in the country. A questionnaire was developed based on ethical frameworks for human challenge studies. The target respondents included those who (...) had experience with health-related research at universities, non-university hospitals, and research institutes. A total of 240 respondents completed the on-line survey. In general, the respondents felt that the ethical issues raised by human challenge studies in LMICS do not differ significantly from those in high income countries, including: scientific rationale, safety, appropriate risks, and robust informed consent process. In contrast, issues that have been described as important for human challenge studies in LMICs were rated as having lower importance, including: a publicly available rationale, national priority, and community engagement. Responses did not vary significantly between researchers in different fields, nor between researchers and REC members. These findings provide an important perspective for assessing existing frameworks for human challenges studies in LMICs. (shrink)

__The Conduct of Inquiry in International Relations_ first edition was winner of the ISA-Northeast’s Yale H. Ferguson Award, and the ISA Theory Section’s Best Book of the Year award._ _The Conduct of Inquiry in International Relations_ provides an introduction to the philosophy of science issues and their implications for the study of global politics. The author draws attention to the problems caused by the misleading notion of a single unified scientific method, and proposes a framework that clarifies the variety of (...) ways that IR scholars establish the authority and validity of their empirical claims. Jackson connects philosophical considerations with concrete issues of research design within neopositivist, critical realist, analyticist, and reflexive approaches to the study of world politics. Envisioning a pluralist science for a global IR field, this volume organizes the significant differences between methodological stances so as to promote internal consistency, public discussion, and worldly insight as the hallmarks of any scientific study of world politics. In this second edition, Jackson has centralised the philosophical history of the ‘science question’ into a single chapter, providing a clearer picture of the connections between contemporary concerns about the status of knowledge and classic philosophical debates about the relationship between human beings and the world they inhabit. The central chapters feature more detailed and pedagogically useful illustrations of the methodological positions discussed, making the book even better suited to clarify the philosophical distinctions with respect to which a scientific researcher must locate herself. The second edition will continue to be essential reading for all students and scholars of International Relations, Political Science and Philosophy of Science. (shrink)

This study examined the influence of two organizational context variables, codes of conduct and supervisor advice, on personnel decisions in an experimental simulation. Specifically, we studied personnel evaluations and decisions in a situation where codes of conduct conflict with supervisor advice. Past studies showed that supervisors’ advice to prefer ingroup over outgroup candidates leads to discriminatory personnel selection decisions. We extended this line of research by studying how codes of conduct and code enforcement may reduce this form of discrimination. Eighty (...) German managers evaluated and selected candidates from an applicant pool including Germans (ingroup members) and foreigners (outgroup members). Supervisor advice to prefer ingroup members lowered suitability ratings of outgroup members as well as their chances to be selected for an interview. Ethical codes of conduct referring to equal opportunities limited this form of discrimination, but only when codes were enforced by sanctions and integrated into organizational every-day practice. The implications of these findings for research and practice are discussed. (shrink)

Who is the whistleblower, and how do they reach the difficult decision to blow the whistle? The article argues that the extant literature has not paid sufficient attention to the profound moral reflexivity in this transition from employee to whistleblower. What is missing, in particular, is a better, sociologically informed, understanding of the various social domains in which whistleblowers are embedded. These domains are important because they provide different kinds of resources for the whistleblower’s moral reflexivity. To pursue this idea, (...) the article conducts a qualitative analysis of 14 whistleblower autobiographies. The analysis is structured around four social domains, which are prevalent in the material: Childhood and adolescence, professional ethics, organizational loyalty, and societal and civic duty values. The autobiographical data clearly demonstrate how whistleblowers actively draw on these domains, and often several of them, as they justify and give meaning to their actions. Such a multidimensional understanding of the whistleblower’s social embeddedness opens up to new ways of analysing the deep personal and moral challenges that most whistleblowers experience.

Background: Heart rate variability (HRV) has been considered as a measure of heart-brain interaction and autonomic modulation, and it is modified by cognitive and attentional tasks. In cognitive tasks, HRV was reduced in participants who achieved worse results. This could indicate the possibility of HRV predicting cognitive performance, but this association is still unclear in a high cognitive load sport such as chess Objective: To analyse modifications on HRV and subjective perception of stress, difficulty and complexity in different chess (...) problem tasks. Design: HRV was assessed at baseline. During the chess problems, HRV was also monitored, and immediately after chess problems the subjective stress, difficulty and complexity were also registered. Method: A total of 16 male chess players, age: 35.19 (13.44) and ELO: 1927.69 (167.78) were analysed while six chess problem solving tasks with different level of difficulty were conducted (two low level, two medium level and two high level chess problems). Participants were classified according to their results into two groups: high performance or low performance. Results: Friedman test showed a significant effect of tasks in HRV indexes and perceived difficulty, stress and complexity in both high and low performance groups. A decrease in HRV was observed in both groups when chess problems difficulty increased. In addition, HRV was significantly higher in the high performance group than in the low performance group during chess problems. Conclusions: An increase in autonomic modulation was observed to meet the cognitive demands of the problems, being higher while the difficulty of the tasks increased. Non-linear HRV indexes seem to be more reactive to tasks difficulty, being an interesting and useful tool in chess training. (shrink)

Key commentators on person‐centred care have described it as a “new ethic of care” which they link inextricably to notions of individual autonomy, action, change and improvement. Two key points are addressed in this article. The first is that few discussions about ethics and person‐centred are underscored by any particular ethical theory. The second point is that despite the espoused benefits of person‐centred care, delivery within the acute care setting remains largely aspirational. Choices nurses make about their practice tend to (...) comply more often with prevailing norms than those championed by person‐centred care. We draw on elements of work by moral philosopher Løgstrup and Foucault to provide insight into nurses’ ethical conduct and ask why nurses would want to act otherwise, when what they think and do is viewed as normal, or think and act otherwise if doing so is seen within the organization as transgressive? To address these more specific questions, we discuss them in relation to the following constructs: the ethical demand, sovereign expressions of life and parrhêsia. We conclude by arguing that a ethical theoretical framework enables nurses to increase their perceptibility and appreciation of the ethical demand particularly those emanating from incommensurability between organizational norms and the norms invoked by person‐centred care. We argue that nurses’ responses to the ethical demand by way of parrhêsia can be an important feature of intra‐organizational reflexivity and its transformation towards the delivery care that is more person‐centred, particularly for older people with cognitive impairment. We conclude the article by highlighting the implications of this for nursing education and research. (shrink)

BackgroundReflexive pitch perturbation experiments are commonly used to investigate the neural mechanisms underlying vocal motor control. In these experiments, the fundamental frequency–the acoustic correlate of pitch–of a speech signal is shifted unexpectedly and played back to the speaker via headphones in near real-time. In response to the shift, speakers increase or decrease their fundamental frequency in the direction opposing the shift so that their perceived pitch is closer to what they intended. The goal of the current work is to develop (...) a quantitative model of responses to reflexive perturbations that can be interpreted in terms of the physiological mechanisms underlying the response and that captures both group-mean data and individual subject responses.MethodsA model framework was established that allowed the specification of several models based on Proportional-Integral-Derivative and State-Space/Directions Into Velocities of Articulators (DIVA) model classes. The performance of 19 models was compared in fitting experimental data from two published studies. The models were evaluated in terms of their ability to capture both population-level responses and individual differences in sensorimotor control processes.ResultsA three-parameter DIVA model performed best when fitting group-mean data from both studies; this model is equivalent to a single-rate state-space model and a first-order low pass filter model. The same model also provided stable estimates of parameters across samples from individual subject data and performed among the best models to differentiate between subjects. The three parameters correspond to gains in the auditory feedback controller’s response to a perceived error, the delay of this response, and the gain of the somatosensory feedback controller’s “resistance” to this correction. Excellent fits were also obtained from a four-parameter model with an additional auditory velocity error term; this model was better able to capture multi-component reflexive responses seen in some individual subjects.ConclusionOur results demonstrate the stereotyped nature of an individual’s responses to pitch perturbations. Further, we identified a model that captures population responses to pitch perturbations and characterizes individual differences in a stable manner with parameters that relate to underlying motor control capabilities. Future work will evaluate the model in characterizing responses from individuals with communication disorders. (shrink)

Background: Black, Asian and minority ethnic groups have a high need for organ transplantation but deceased donation is low. This restricts the availability of well-matched organs and results in relatively long waiting times for transplantation, with increased mortality risks. Objective: To identify barriers to organ donor registration and family consent among the BAME population, and to develop and evaluate a training intervention to enhance communication with ethnic minority families and identify impacts on family consent. Methods: Three-phase programme comprising community-based research (...) involving two systematic reviews examining attitudes and barriers to organ donation and effective interventions followed by 22 focus groups with minority ethnic groups; hospital-based research examining staff practices and influences on family consent through ethics discussion groups with staff, a study on intensive care units and interviews with bereaved ethnic minority families; and development and evaluation of a training package to enhance cultural competence among ICU staff. Setting: Community focus group study in eight London boroughs with high prevalence of ethnic minority populations. Hospital studies at five NHS hospital trusts. Participants: Community studies: 228 focus group participants; hospital studies: 35 nurses, 28 clinicians, 19 hospital chaplains, 25 members of local Organ Donation Committees, 17 bereaved family members; and evaluation: 66 health professionals. Data sources: Focus groups with community residents, systematic reviews, qualitative interviews and observation in ICUs, EDGs with ICU staff, bereaved family interviews and questionnaires for trial evaluation. Review methods: Systematic review and narrative synthesis. Results: Community studies: Organ Donor Register – different ethnic/faith and age groups were at varying points on the ‘pathway’ to organ donor registration, with large numbers lacking knowledge and remaining at a pre-contemplation stage. Key attitudinal barriers were uncertainties regarding religious permissibility, bodily concerns, lack of trust in health professionals and little priority given to registration, with the varying significance of these factors varying by ethnicity/faith and age. National campaigns focusing on ethnic minorities have had limited impact, whereas characteristics of effective educational interventions are being conducted in a familiar environment; addressing the groups’ particular concerns; delivery by trained members of the lay community; and providing immediate access to registration. Interventions are also required to target those at specific stages of the donation pathway. Hospital studies: family consent to donation – many ICU staff, especially junior nurses, described a lack of confidence in communication and supporting ethnic minority families, often reflecting differences in emotional expression, faith and cultural beliefs, and language difficulties. The continuing high proportion of family donation discussions that take place without the collaboration of a specialist nurse for organ donation reflected consultants’ views of their own role in family consent to donation, a lack of trust in SNODs and uncertainties surrounding controlled donations after circulatory death. Hospital chaplains differed in their involvement in ICUs, reflecting their availability/employment status, personal interests and the practices of ICU staff. Evaluation: professional development package – a digital versatile disk-based training package was developed to promote confidence and skills in cross-cultural communication. Initial evaluation produced positive feedback and significant affirmative attitudinal change but no significant difference in consent rate over the short follow-up period with requirements for longer-term evaluation. Limitations: Participants in the focus group study were mainly first-generation migrants of manual socioeconomic groups. It was not permitted to identify non-consenting families for interview with data regarding the consent process were therefore limited to consenting families. Conclusions: The research presents guidance for the effective targeting of donation campaigns focusing on minority ethnic groups and provides the first training package in cultural competence in the NHS. Future work: Greater evaluation is required of community interventions in the UK to enhance knowledge of effective practice and analysis of the experiences of non-consenting ethnic minority families.

Although much of the focus on responsible conduct in research has been defined by courses or online training, it is generally understood that this is less important than what happens in the research environment. On the assumption that providing faculty with tools and resources to address the ethical dimensions of the practice of research would be useful, a new workshop was convened ten times across seven academic institutions and at the annual meeting of a professional society. Workshops were attended by (...) 91 faculty, 71 of whom completed evaluations strongly supportive of the value of the workshop. Surveys of trainees identified by the faculty allowed for invitations to complete an online survey before and 6 months after the workshops, respectively resulting in response rates of 43 and 51%. Faculty and trainees were highly supportive of the feasibility, relevance, and effectiveness of the implementation by the faculty of one or more of the five strategies featured in the workshop. However, surprisingly over 70% of the trainees reported use of one or more of those strategies prior to faculty participation in the workshops. In sum, the workshops for faculty were successful, and the proposed strategies were deemed of value, but it is likely that the faculty voluntarily choosing to participate in these workshops were perhaps not surprisingly faculty who are already engaging in some of these strategies. This model is likely a useful adjunct to encouraging a culture of ethics, but it is not by itself sufficient to do so. (shrink)

ObjectiveNoisy galvanic vestibular stimulation (nGVS) is often used to improve postural stability in disorders, such as neurorehabilitation montage. For the safe use of nGVS, we investigated whether arterial pressure (AP) and heart rate vary during static supine and slow whole-body tilt with random nGVS (0.4 mA, 0.1–640 Hz, gaussian distribution) in a healthy elderly population.MethodsThis study was conducted with a double-blind, sham-controlled, cross-over design. Seventeen healthy older adults were recruited. They were asked to maintain a static supine position on (...) a bed for 10 min, and the bed was tilted up (TU) to 70 degrees within 30 s. After maintaining this position for 3 min, the bed was passively tilted down (TD) within 30 s. Real-nGVS or sham-nGVS was applied from 4 to 15 min. The time course of mean arterial pressure (MAP) and RR interval variability (RRIV) were analyzed to estimate the autonomic nervous activity.ResultnGVS and/or time, including pre-/post-event (nGVS-start, TU, and TD), had no impact on MAP and RRIV-related parameters. Further, there was no evidence supporting the argument that nGVS induces pain, vertigo/dizziness, and uncomfortable feeling.ConclusionnGVS may not affect the AP and RRIV during static position and whole-body tilting or cause pain, vertigo/dizziness, and discomfort in the elderly.

ABSTRACTMany social scientific studies have shown the positive effects of self-awareness and reflexivity in shaping individuals’ career paths. However, using life- and work-history interviews conducted with salespersons in Toronto, Canada, I find that high levels of self-awareness – as demonstrated by active deliberation over one’s career – has both positive and negative results in terms of career outcomes. Respondents whose careers initially progressed as they expected tended to benefit from reflexively managing their careers. However, the benefits of reflexivity were mixed (...) for respondents whose careers did not begin as planned. This group of respondents sometimes benefited from thinking about alternatives; but also, sometimes, cast themselves outside of careers that they deemed to be ‘normal’. Observing the way that some respondents formed new career plans based on unmet expectations, and began to pursue those emergent plans, I argue that scholarly uses of reflexivity should incorporate its function as a potential career trajectory anchor.

OBJECTIVES: This reliability generalization study aimed to estimate the mean and variance of the interrater reliability coefficients (ryy) of supervisory ratings of overall, task, contextual, and positive job performance. The moderating effect of the appraisal purpose and the scale type was examined. It was hypothesized that the ratings collected for research purposes and multi-item scales have higher ryy. It was also examined whether ryy was similar for the four performance dimensions. METHOD: A database consisting of 224 independent samples was created (...) and hierarchical sub-grouping meta-analyses were conducted. RESULTS: The appraisal purpose was a moderator of ryy for the four performance dimensions. Scale type was a moderator of ryy for overall and task performance collected for research purposes. The findings also suggest that supervisors seem to have less difficulty evaluating overall job performance than task, contextual, and positive performance. The best estimates of the observed ryy for overall job performance are.61 for research-collected ratings and.45 for administrative-collected ratings. MAIN CONCLUSIONS: (1) Appraisal purpose moderates ryy and researchers and practitioners should be aware of its effects before collecting ratings or using empirically-derived interrater reliability distributions, (2) Scale type seems to moderate ryy in the case of the ratings collected for research purposes, only, (3) overall job performance is more reliably rated than task, contextual, and positive performance. Implications for research and practice are discussed. (shrink)

This paper explores the application of positionality and reflexivity drawing on the experience of a British Minority Ethnic (BME) group senior nurse researching nurses with the same ethnic heritage in an IPA study. It explores how using IPA informed reflexivity and positionality as a researcher who shared the same ethnicity with the research participants. The IPA study allowed for the exploration of Internationally Educated Nurses' (IENs) perspectives on their integration into British healthcare and their navigation of career progression. The central (...) aims of an IPA study are to understand the participant's world, its description, the development of a clear, and open interpretative analysis with a descriptive focus on the social, cultural and theoretical context, and the participant's sense‐making of their lived experience. In this paper, we discuss how the lead researcher employed reflexivity, stated his intentionality and positionality in the conduct of the IPA study. This paper discusses some examples of the effects of positionality and reflexivity in the conduct of research by researchers of different racial background, and explicate the influence of personal and professional experiences of a researcher in using reflexivity and positionality to ensure cross‐cultural validity and reliability of an IPA research. This paper concludes that appropriate use of reflexivity and positionality in an IPA study may recognise the personal and professional influence of a researcher's experiences on the research process, including their ethnicity.

ABSTRACT:The ethical sensemaking approach stands as an essential alternative to the dominant rational and objectivist paradigm of ethical decision-making in organizations. From this perspective, this research explores the intrapersonal interplay of emotions and reflexivity in ethical sensemaking. We analyzed thirty-seven semi-structured interviews conducted with executive coaches sharing a critical incident about an issue they framed as ethical. Our findings show that their ethical decisions unfolded over a three-phase emotional reflexive sensemaking process, where reflexivity allowed for the management of emotions in (...) the form of emotional awareness, emotional unpacking, and emotional engagement. Therefore, we portray ethics as afabric, produced through the knitting of emotions and reflexivity. And, while ethics certainly appear to be produced by the subject, we suggest a reciprocal relationship, whereby the very fabric of ethics contributes to the production of the ethical subject.

Isolated feedforward networks (FFNs) of spiking neurons have been studied extensively for their ability to propagate transient synchrony and asynchronous firing rates, in the presence of activity independent synaptic background noise (Diesmann et al., 1999; van Rossum et al., 2002). In a biologically realistic scenario, however, the FFN should be embedded in a recurrent network, such that the activity in the FFN and the network activity may dynamically interact. Previously, transient synchrony propagating in an FFN was found to destabilize the (...) dynamics of the embedding network (Mehring et al., 2003). Here, we show that by modeling synapses as conductance transients, rather than current sources, it is possible to embed and propagate transient synchrony in the FFN, without destabilizing the background network dynamics. However, the network activity has a strong impact on the type of activity that can be propagated in the embedded FFN. Global synchrony and high firing rates in the embedding network prohibit the propagation of both, synchronous and asynchronous spiking activity. In contrast, asynchronous low-rate network states support the propagation of both, synchronous spiking and asynchro- nous, but only low firing rates. In either case, spiking activity tends to synchronize as it propagates, challenging the feasibility to transmit information in asynchronous firing rates. Finally, asynchronous network activity allows to embed more than one FFN, with the amount of cross talk depending on the degree of overlap in the FFNs. This opens the possibility of computational mechanisms using transient synchrony among the activities in multiple FFNs. (shrink)

The application of machine learning algorithms to healthcare data can enhance patient care while also reducing healthcare worker cognitive load. These algorithms can be used to detect anomalous physiological readings, potentially leading to expedited emergency response or new knowledge about the development of a health condition. However, while there has been much research conducted in assessing the performance of anomaly detection algorithms on well-known public datasets, there is less conceptual comparison across unsupervised and supervised performance on physiological data. Moreover, while (...) heart rate data are both ubiquitous and noninvasive, there has been little research specifically for anomaly detection of this type of data. Considering that heart rate data are indicative of both potential health complications and an individual’s physical activity, this is a rich source of largely overlooked data. To this end, we employed and evaluated five machine learning algorithms, two of which are unsupervised and the remaining three supervised, in their ability to detect anomalies in heart rate data. These algorithms were then evaluated on real heart rate data. Findings supported the effectiveness of local outlier factor and random forests algorithms in the task of heart rate anomaly detection, as each model generalized well from their training on simulated heart rate data to real world heart rate data. Furthermore, results support that simulated data can help configure algorithms to a degree of performance when real labeled data are not available and that this type of learning might be especially helpful in initial deployment of a system without prior data.

The integrity of critical ethnography requires engagement in reflexive practice at all phases of the research process. In this discussion paper, I explore the insights and challenges of reflexive practice in an ethnographic study of the recovery experiences of black trauma patients in a Philadelphia hospital. Observation and interviews were conducted with twelve patients who were admitted to trauma‐designated units of the hospital over the course of a year. During fieldwork, I learned the ways that my background as a professional (...) nurse structured my way of being in clinical space and facilitated a particular interpretation of clinical culture. In analysis, reflection on subjectivities through which I designed this ethnographic research allowed me to see beyond my preconceived and theoretically informed perspective to permit unexpected features of the field to emerge. Reflexive practice also guided my reconciliation of key practical and epistemological differences between clinical ethnographic research and the anthropologic tradition in which it is rooted. I conclude that with careful reflection to the subjectivities that influence the research process, interdisciplinary clinically relevant applied interpretations of critical ethnographic work can be used to generate detailed knowledge across contexts in clinical care, nursing practice, and patient experiences.

Online tools are increasingly being used by students to cheat. File-sharing and homework-helper websites offer to aid students in their studies, but are vulnerable to misuse, and are increasingly reported as a major source of academic misconduct. Chegg.com is the largest such website. Despite this, there is little public information about the use of Chegg as a cheating tool. This is a critical omission, as for institutions to effectively tackle this threat, they must have a sophisticated understanding of their use. (...) To address this gap, this work reports on a comprehensive audit of Chegg usage conducted within an Australian university engineering school. We provide a detailed analysis of the growth of Chegg, its use within an Australian university engineering school, and the wait time to receive solutions. Alarmingly, we found over half of audit units had cheating content on Chegg is broadly used to cheat and 50% of questions asked on Chegg are answered within 1.5 h. This makes Chegg an appealing tool for academic misconduct in both assignment tasks and online exams. We further investigate the growth of Chegg and show its use is above pre-pandemic levels. This work provides valuable insights to educators and institutions looking to improve the integrity of their courses through assessment and policy development. Finally, to better understand and tackle this form of misconduct, we call on education institutions to be more transparent in reporting misconduct data and for homework-helper websites to improve defences against misuse.

Social media offers an attractive site for Big Data research. Access to big social media data, however, is controlled by companies that privilege corporate, governmental, and private research firms. Additionally, Institutional Review Boards’ regulative practices and slow adaptation to emerging ethical dilemmas in online contexts creates challenges for Big Data researchers. We examine these challenges in the context of a feminist qualitative Big Data analysis of the hashtag event #WhyIStayed. We argue power, context, and subjugated knowledges must each be central (...) considerations in conducting Big Data social media research. In doing so, this paper offers a feminist practice of holistic reflexivity in order to help social media researchers navigate and negotiate this terrain. (shrink)
