This study investigates the determinants of paternal investment by birth fathers and stepfathers. Inclusive fitness theory predicts higher parental investment in birth children than stepchildren, and this has consistently been found in previous studies. Here we investigate whether paternal investment varies with childhood co-residence duration and differs between stepfathers and divorced birth fathers by comparing the investment of (1) stepfathers, (2) birth fathers who are separated from the child’s mother, and (3) birth fathers who still are in a relationship with her. Path analysis was conducted using cross-sectional data from adolescents and younger adults (aged 17–19, 27–29, and 37–39 years) from the German Family Panel (pairfam), collected in 2010–2011 (_n_ = 8326). As proxies of paternal investment, we used financial and practical help, emotional support, intimacy, and emotional closeness, as reported by the children. We found that birth fathers who were still in a relationship with the mother invested the most, and stepfathers invested the least. Furthermore, the investment of both separated fathers and stepfathers increased with the duration of co-residence with the child. However, in the case of financial help and intimacy, the effect of childhood co-residence duration was stronger in stepfathers than in separated fathers. Our findings support inclusive fitness theory and mating effort theory in explaining social behavior and family dynamics in this population. Furthermore, social environment, such as childhood co-residence was associated with paternal investment.

Contemporary epidemiological methods testing the associations between green space and psychological well-being treat all vegetation cover as equal. However, there is very good reason to expect that variations in ecological "quality" (number of species, integrity of ecological processes) may influence the link between access to green space and benefits to human health and well-being. We test the relationship between green space quality and restorative benefit in an inner city urban population in Bradford, UK. We selected 12 urban parks for study where we carried out botanical and faunal surveys to quantify biodiversity and assessed the site facilities of the green space (cleanliness, provision of amenities). We also conducted 128 surveys with park users to quantify psychological restoration based on four self-reported measure of general restoration, attention-grabbing distractions, being away from everyday life, and site preference. We present three key results. First, there is a positive association between site facilities and biodiversity. Second, restorative benefit is predicted by biodiversity, which explained 43% of the variance in restorative benefit across the parks, with minimal input from other variables. Third, the benefits accrued through access to green space were unrelated to age, gender, and ethnic background. The results add to a small but growing body of evidence that emphasise the role of nature in contributing to the well-being of urban populations and, hence, the need to consider biodiversity in the design of landscapes that enhance multiple ecosystem services.

In this work we address the proposition that because it emerges from the contract tradition and so relies upon the assumption of mutual advantage, John Rawls' theory of “Justice as Fairness” cannot accommodate persons with severe mental and/or physical impairments. We respond to this criticism by proposing a revision to Rawls' contracting situation, the Original Position . Specifically, we propose to supplant the traditional understanding of mutual advantage—which we agree does constitute the necessary and sufficient condition for deliberation to come about in the OP, as it stands—with a more modest alternative: a Hobbes-inspired concept that we call minimal mutual advantage. We argue that when this revision is introduced into Justice as Fairness, it reconciles admirably the seeming tension between contractarianism’s insistence on the rational, self-interested actor and the reality of societies in which not all members are capable of meeting a standard of reciprocity understood in terms of productive contributions to the general well-being. In so doing, minimal mutual advantage renders indistinguishable the disabled from the able in the OP, allowing Justice as Fairness to capture successfully problems of disability while leaving intact the more appealing aspects of liberalism that other approaches would dismiss.

The impact of emotion on executive functioning is gaining interest. It has led to the differentiation of “cool” Executive Functioning processes, such as cognitive flexibility, and “hot” EF processes, such as affective flexibility. But how does affective flexibility, the ability to switch between cognitive and affective information, vary as a function of age and sex? How does this construct relate to “cool” executive functioning and cognitive-emotion regulation processes? In this study, 266 participants, including 91 adolescents and 175 adults, completed a cognitive–affective switching task with specific unpredictable switches, as well as measures of inhibition, attention, and cognitive-emotion coping strategies. We expected cognitive to affective switching to be more costly than affective to cognitive switching in females versus males, as well as higher switch costs in adolescents. Using linear mixed modelling, we analysed the effect of age, sex, and types of switching on reaction time. Results show that adolescents are slower switchers than adults, and demonstrate that females, although faster switchers than males, are slower when switching from cognitive to affective content than when they are switching from affective to cognitive content. Multiple regression analyses revealed age-specific associations between cognitive-affective switching and inhibition. These results converge with reported developmental and gender specificities in EF and emotion processing, respectively. Additionally, affective flexibility could relate to differences in vigilance and inhibition.

The purpose of this paper is to identify the way in which art can disrupt the subject’s everyday experience of the world and self. The proposal starts from the hypothesis that art offers experiences of embodied disrupted reality, and this statement is based on the parallelism between certain artistic experiences and certain psychological conditions that are known as dissociative disorders, which challenge the subject’s sense of reality and self, and lead the subject to experience some level of detachment and a sense of loss of familiarity with respect to the world and the self. These aspects are also particularly felt in immersive environments. Immersive technologies offer an important laboratory for perception and sensoriality, taking into consideration the embodied basis and the first-person perspective of the user-experimenter. In this context, art offers a series of strategies that allow the user to undergo a shift in experience, affecting the sense of embodiment and reality. To explore these notions, I refer to some phenomenological implications of the experience of dissociative disorders and the interrelation between art, technology, and dissociative disorders. Finally, I offer an analysis of three artistic interdisciplinary projects, taking into account the particular ways of embodiment and sense of reality they trigger in the user. Based on the parallelism between art and dissociative disorders and its dialogue with immersive technologies, this article aims to contribute to a phenomenology of embodied disrupted reality from art.

The present study was designed to explore the relationship between self-reported dissociative experiences and performance in tasks eliciting right-hemisphere processing load. Thirty-four participants performed a vigilance task in two conditions: with task-irrelevant negative-arousing pictures and task-irrelevant neutral pictures. Dissociation was assessed with the Dissociative Experience Scale. Consistent with theories positing right-hemisphere deregulation in high non-clinical dissociators, dissociative experiences correlated with greater vigilance decrement only in the negative picture condition. As both the vigilance task and negative picture processing are right lateralized, this result provides support for a right-hemisphere dysfunction in high dissociators, at least in negative conditions

Background: Increasing use of genetic technologies in clinical and research settings increases the potential for misattributed paternity to be identified. Yet existing guidance from the President's Commission for the Study of Ethical Problems in Biomedical and Behavioral Research and the Institute of Medicine (among others) offers contradictory advice. Genetic health professionals are thus likely to vary in their practice when misattributed paternity is identified, and empirical investigation into the disclosure of misattributed paternity is scarce. Given the relevance of this ethical dilemma and its significance to users of genetic services, this study aimed to investigate the attitudes of lay people with regard to the disclosure of misattributed paternity. Methods: An online questionnaire was hosted and advertised through Amazon's Mechanical Turk to 200 United States residents aged 18 years or older. Respondents were asked to rate (via a Likert scale) the ethical permissibility of possible actions a clinician may carry out when misattributed paternity is identified. Data analysis consisted of preliminary descriptive analysis, chi-squared analysis, and Wilcoxon signed-rank tests. Results: There was no clear majority support for many of the options surveyed across different contexts, with only six out of ten scenarios displaying some general consensus. Men were more likely to support scenarios where the father is informed of paternity. Importantly, participants' views varied according to whether the desires of the father were previously expressed, suggesting that perceptions of the permissibility of a clinician's action will depend on the interests of all parties affected. Conclusions: This sample of the general public showed attitudes that were, at least to some degree, at variance with some professional guidelines. We give arguments for why at least some of these attitudes might be justified. We argue that case-specific judgments should be made and outline some of the relevant ethical considerations. While general guidelines ought to be considered, context-specific moral judgments cannot be avoided.

Two studies employed a dissociative detachment induction technique to examine if experiences of dissociation increased acute shame feelings. Study 1 recruited college participants, while Study 2 enlisted adults attending treatment for childhood sexual abuse. Two hypotheses were explored: (1) more shame would be reported following a dissociative detachment induction than a relaxation induction; and (2) shame would increase when detachment was induced in the relationship context of a close other than when alone. Study 1 (N = 81) effectively induced detachment and participants reported higher shame in this condition compared to the relaxation condition. This effect was maintained when state anxiety was controlled. The relationship context produced no impact on dissociation or shame. Attributions around feeling flawed predominantly linked detachment experiences with subsequent shame feelings. In Study 2 with clinical participants (N = 28), regression analyses showed state shame was predicted by acute detachment after controlling for state anxiety, gender, and trait shame and dissociation. The most common appraisals offered for why detachment led to feelings of shame was being flawed and exposed. Collectively, our findings suggest that increased acute shame results from detachment experiences, making more specific the relationship between shame and dissociation.

This article describes the causes and health consequences of environmental degradation and social injustice. These issues, which impact primarily on the poor and underserved (both in the United States and internationally) are rarely or inadequately covered in the curriculums of traditional health care professions. The discussion offers ways for health care professionals to promote equality and justice and uses the example of Rudolph Virchow’s social activinsm to illustrate how one physician can lead society toward major public health gains. There is also an examination of the roles of institutions and organisations in enhancing environmental preservation and promoting social justice. Specific curricular suggestions from history and the humanities are offered for those teaching and mentoring new health professionals.
