Adaptive immunity provides the unique ability to respond to a nearly infinite range of antigenic determinants. Given the inherent plasticity of the adaptive immune system, a series of tolerance mechanisms exist to reduce reactivity toward self. While this reduces the probability of autoimmunity, it also creates an important gap in adaptive immunity: the ability to recognize microbes that look like self. As a variety of microbes decorate themselves in self‐like carbohydrate antigens and tolerance reduces the ability of adaptive immunity to (...) react with self‐like structures, protection against molecular mimicry likely resides within the innate arm of immunity. In this review, we will explore the potential consequences of microbial molecular mimicry, including factors within innate immunity that appear to specifically target microbes expressing self‐like antigens, and therefore provide protection against molecular mimicry.

The novelty of the coronavirus disease 2019 pandemic is that it is occurring in a globalized society enhanced by digital capabilities. Our aim was to analyze the psychological and emotional states of participants in different pandemic-related contexts, with a focus on their digital and physical distancing behaviors. The online survey was applied during the ascending phase of the pandemic in March 2020 in two neighboring EU countries: Italy and Croatia. The study subjects involved four groups, two directly affected by epidemiological (...) measures and two serving as controls— participants from Italy who were in lockdown, participants from Croatia who were not in lockdown but who were in direct contact with an infected person and underwent epidemiological measures, participants from Croatia who were in an analogous situation but not near the same infected person, and participants from Croatia who were not aware of any infected person. The survey consisted of validated scales of psychological and emotional states, and custom-made questionnaires on the digital and physical behavior of the participants. The Italy group in lockdown had higher self-perceived scores for depression, stress, post-traumatic intrusion, and avoidance, as well as the highest digital activity and physical distancing than the not-in-lockdown Croatian groups. The insight into the extent of online activities and off-line isolation allowed for the introduction of Digital Activity and Physical Distancing Scores. Self-perceived post-traumatic avoidance was higher in both the Italy and CRO-contact groups than the control CRO-no contact and CRO-unrelated groups, and higher avoidance correlated with higher Digital Activity and Physical Distancing Scores. Being in direct contact with the infected person, the CRO-contact group had no other alterations than unexpectedly lower post-traumatic hyperarousal when compared with the Italy group. The Italy group in lockdown demonstrated higher self-perceived psychological toll together with higher digital activity and physical distancing than Croatian groups not in lockdown, even when compared with the affected CRO-contact group. The study outcomes suggest that the general emergency measures influenced citizens in lockdown more than exposure to the virus through direct contact with an infected person. (shrink)

Background: There are numerous benefits to ethics consultation services, but little is known about the reasons different professionals may or may not request an ethics consultation. Inter-professional differences in the perceived utility of ethics consultation have not previously been studied.Methods: To understand profession-specific perceived benefits of ethics consultation, we surveyed all employees at an urban tertiary children’s hospital about their use of ethics committee services (n = 842).Results: Our findings suggest that nurses and physicians find ethics consultations useful for different (...) reasons; physicians were more likely to report normative benefits, while nurses were more likely to report communicative and relational benefits.Conclusions: These findings support an open model of ethics consultation and may also help ethics committees to better understand consultation requests and remain attuned to the needs of various professional groups.

Since male CEOs dominate corporate leadership, the literature on top management decision making suffers from an implicit masculine bias. Although research indicates that males and females are biologically and psychologically different, the leadership characteristics of female CEOs are largely unexplored. Two of these characteristics, risk aversion and ethical sensitivity, are tied to key accounting issues, such as conservatism in financial reporting and steadfast opposition to fraud. In this study, we examine the relationship between CEO gender and accounting conservatism, and find (...) a positive association between the two. Consistent with conventional wisdom, this association appears to be stronger in firms with high rather than low litigation and takeover risks. This study contributes to the ethics literature by highlighting the benefits of gender diversity in upholding the integrity of financial reporting. (shrink)

The inaugural collection in an exciting new exchange between philosophers and geographers, this volume provides interdisciplinary approaches to the environment as space, place, and idea. Never before have philosophers and geographers approached each other's subjects in such a strong spirit of mutual understanding. The result is a concrete exploration of the human-nature relationship that embraces strong normative approaches to environmental problems.

Background: It is not known how neonatologists address the affective and cognitive loads on parents deciding whether to resuscitate infants born extremely preterm. This study explores expert neonatologists' views on these decision-making processes and their own roles in counseling parents. Methods: Semistructured interviews asked internationally recognized experts to share their perspectives on perinatal consultations. Their responses were subjected to thematic analysis. Results: Eighteen of 22 invited experts participated. Approximately equal numbers reported employing a physician-driven approach, a parent-driven approach, and a (...) combined approach during these consultations. Those who followed a physician-driven approach typically focused on conveying standard information about adverse outcomes. Those who followed a parent-driven approach typically focused on addressing parents' information requests, guiding their decision making, and providing affective support. Nearly all experts, in each group, endorsed addressing the child's quality of life, in terms of functionality, when discussing long-term outcomes. Although many believed that families adjusted to life with a disabled child, few discussed the topic during prenatal consultations. Most, in each group, reported trying to alleviate future “decisional regret” for parents whose premature infants subsequently became disabled. None spoke to parents about possible decisional regret after deciding to forgo resuscitation. Conclusions: Expert neonatologists are deeply concerned that parents understand the decision facing them. However, they differ on what information they offer and how they balance parents' need for cognitive and affective support. They expressed more concern about parents' decisional regret should their child survive resuscitation, but have severe disability, than about decisional regret after foregoing resuscitation.

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

Research on bilingualism has grown exponentially in recent years. However, the comprehension of speech in noise, given the ubiquity of both bilingualism and noisy environments, has seen only limited focus. Electroencephalogram studies in monolinguals show an increase in alpha power when listening to speech in noise, which, in the theoretical context where alpha power indexes attentional control, is thought to reflect an increase in attentional demands. In the current study, English/French bilinguals with similar second language proficiency and who varied in (...) terms of age of L2 acquisition from 0 to 15 years completed a speech perception in noise task. Participants were required to identify the final word of high and low semantically constrained auditory sentences such as “Stir your coffee with a spoon” vs. “Bob could have known about the spoon” in both of their languages and in both noise and quiet during electrophysiological recording. We examined the effects of language, AoA, semantic constraint, and listening condition on participants’ induced alpha power during speech comprehension. Our results show an increase in alpha power when participants were listening in their L2, suggesting that listening in an L2 requires additional attentional control compared to the first language, particularly early in processing during word identification. Additionally, despite similar proficiency across participants, our results suggest that under difficult processing demands, AoA modulates the amount of attention required to process the second language.

This article reviews existing approaches to defining and distinguishing communication styles and proposes a common frame of reference for future research. The literature review yields two schools of thought: the behavior-centered perspective and the personality-oriented perspective. Although these lines of research differ in their ways of defining communication styles, they show considerable similarities with respect to their classification. Many researchers build their taxonomies on two key dimensions: assertiveness and responsiveness. We propose embedding communication styles into the Five-Factor Theory and defining (...) them as characteristic adaptations of personality. We also suggest the Interpersonal Circumplex as a reference model for distinguishing communication styles as it is able to integrate substantial dimensions and facets of existing taxonomies in a parsimonious way.

BackgroundChildhood adversity is linked to adverse health in adulthood. One posited mechanistic pathway is through physiological responses to acute stress. Childhood adversity has been previously related to both exaggerated and blunted physiological responses to acute stress, however, less is known about the psychological mechanisms which may contribute to patterns of physiological reactivity linked to childhood adversity.ObjectiveIn the current work, we investigated the role of challenge and threat stress appraisals in explaining relationships between childhood adversity and cortisol reactivity in response to (...) an acute stressor.MethodsUndergraduate students completed an online survey that included general demographic information and the Risky Families Questionnaire 24 h before a scheduled lab visit. In the lab, a research assistant collected a baseline salivary cortisol sample. Following the baseline period, participants were read instructions for the Trier Social Stress Test, a validated psychological lab stressor. Next, they completed a challenge vs. threat task appraisal questionnaire and completed the speech and math portion of the TSST. Twenty minutes following the start of the TSST, a second salivary sample was collected to measure changes in salivary cortisol following the TSST.ResultsLinear regression analyses adjusted for age, sex, childhood socioeconomic status, and baseline cortisol levels, showed childhood adversity associated with changes in cortisol levels [B = –0.29 t = –2.35, p = 0.02, R2=0.07]. Linear regression analyses controlling for age, sex, and childhood SES showed childhood adversity associated with both challenge [B = –0.52 t = –5.04, p < 0.001, R2=0.24] and threat [B = 0.55 t = 5.40, p < 0.001, R2=0.27] appraisals. Significant indirect effects of childhood trauma on cortisol reactivity were observed through challenge appraisals [B = –0.01 ], and threat appraisals [B = –0.01 ].ConclusionChildhood adversity may contribute to blunted cortisol reactivity, a pattern of response which is linked to obesity, addiction, and other behavior-related diseases. Our findings suggest that this relationship is in part a product of stress appraisals. (shrink)

Epigenetic research has brought several important technological achievements, including identifying epigenetic clocks and signatures, and developing epigenetic editing. The potential military applications of such technologies we discuss are stratifying soldiers’ health, exposure to trauma using epigenetic testing, information about biological clocks, confirming child soldiers’ minor status using epigenetic clocks, and inducing epigenetic modifications in soldiers. These uses could become a reality. This article presents a comprehensive literature review, and analysis by interdisciplinary experts of the scientific, legal, ethical, and societal issues (...) surrounding epigenetics and the military. Notwithstanding the potential benefit from these applications, our findings indicate that the current lack of scientific validation for epigenetic technologies suggests a careful scientific review and the establishment of a robust governance framework before consideration for use in the military. In this article, we highlight general concerns about the application of epigenetic technologies in the military context, especially discrimination and data privacy issues if soldiers are used as research subjects. We also highlight the potential of epigenetic clocks to support child soldiers’ rights and ethical questions about using epigenetic engineering for soldiers’ enhancement and conclude with considerations for an ethical framework for epigenetic applications in the military, defense, and security contexts.

This article begins with a review of the literature on the ethics of tax evasion and identifies the three main views that have emerged over the centuries, namely always ethical, sometimes ethical, and never or almost never ethical. It then reports on the results of a survey of HK and U.S. university business students who were asked to express their opinions on the 15 statements covering the three main views. The data are then analyzed to determine which of the three (...) viewpoints is dominant among the sample population. Although it was found that HK scores were significantly different from the U.S. scores, both HK and U.S. respondents were opposed to the view that tax evasion is always or almost always ethical. The strongest arguments justifying tax evasion were in cases where the government was corrupt, the tax system was unfair and unaffordable. The weakest arguments for justifying tax evasion were in cases where there was a selfish motive. The underlying cultural differences are further explored in hope of accounting for differing perceptions of ethics of tax evasion. Policy implications for increasing people’s awareness of ethics on tax evasion are also highlighted. (shrink)

Sensory processing dysfunction is characterized by a behaviorally observed difference in the response to sensory information from the environment. While the cerebellum is involved in normal sensory processing, it has not yet been examined in SPD. Diffusion tensor imaging scans of children with SPD and typically developing controls were compared for fractional anisotropy, mean diffusivity, radial diffusivity, and axial diffusivity across the following cerebellar tracts: the middle cerebellar peduncles, superior cerebellar peduncles, and cerebral peduncles. Compared to TDC, children with SPD (...) show reduced microstructural integrity of the SCP and MCP, characterized by reduced FA and increased MD and RD, which correlates with abnormal auditory behavior, multisensory integration, and attention, but not tactile behavior or direct measures of auditory discrimination. In contradistinction, decreased CP microstructural integrity in SPD correlates with abnormal tactile and auditory behavior and direct measures of auditory discrimination, but not multisensory integration or attention. Hence, altered cerebellar white matter organization is associated with complex sensory behavior and attention in SPD, which prompts further consideration of diagnostic measures and treatments to better serve affected individuals.

An anxious resident paged ethics at 2:00 a.m. His patient, Mr. M, a twenty‐nine‐year‐old man with a history of multiple substance abuse, was in the hospital after cardiac arrest and lack of cerebral perfusion. Sadly, the young man probably met the criteria for brain death, but the final apnea test to confirm the diagnosis could not be done for another forty‐eight to seventy‐two hours because the Klonopin in his system might confound the results. The resident's concern, however, addressed a request (...) made by the patient's mother for a sperm harvest. The patient's mother maintained that her son had said he wanted to give her grandchildren. She wished to harvest sperm from him for a future use with an as‐yet‐to‐be‐determined surrogate mother. (shrink)

When Annie Besant landed in India she disavowed all political intent, but she soon became a militant nationalist — the only Western woman ever elected President of Congress. This essay explains her entry into politics by tracing the way her secular and socialist heritage informed her intellectual challenge to the ruling discourse of the Raj. In Britain, her theosophy acted as an alternative religious discourse, combining aspects of a secularist critique of Christianity with a defence of Eastern religions. In (...) India, it acted as a religious and social discourse that asserted the legitimacy, even superiority, of the indigenous culture. More generally, a study of Besant's opposition to the Raj illuminates the logic of a view of India shared by many nationalists. It shows how this view of India arose in dialectical opposition to the legitimating discourse of empire. (shrink)
