Relatives play an important role in human reproduction according to evolutionary theories of reproductive behavior, but previous empirical studies show large differences in the effects of kin on fertility outcomes. In our paper we examine the effect of co-resident kin and non-kin on the length of birth intervals over the reproductive life course of Dutch women born between 1842 and 1920. We estimate Cox proportional hazard models for parity progression based on the presence of kin and non-kin in the household (...) while controlling for a large number of individual and community-level characteristics. We find that couples living with their brothers experienced shorter birth intervals whereas couples residing with a widowed father had relatively longer birth intervals. The effects of these types of kin on reproduction were most pronounced up to the birth of the fifth child, but not thereafter. We found no effect for mothers or other types of kin. (shrink)

This book is a survey of the range of apparently miraculous accidents of nature that have enabled the universe to evolve its familiar structures (atoms, stars, galaxies, and life itself) concludes with an investigation of the so-called anthropic principle.

While citizens often use non-instrumental arguments to support environmental protection, most governmental policies are justified by instrumental arguments. This paper explores some of the reasons. We interviewed senior policy advisors to four European governments active in global climate change negotiations and the UNCED (United Nations Conference on Environment and Development) process. In response to our questions, a majority of these advisors articulated deeply held personal environmental values. They told us that they normally keep these values separate from their professional environmental (...) policy activities. We interpret these findings within the context of the literature on environmental ethics and values. We suggest that environmental policy could be improved if widely held environmental values were articulated, validated, and admitted into the process of policy analysis and deliberation. (shrink)

As a 2006 Institute of Medicine report highlights, surprisingly little empirical attention has been paid to how prisoners arrive at decisions to participate in modern research. With our study, we aimed to fill this gap by identifying a more comprehensive range of factors as reported by prisoners themselves during semistructured interviews. Our participants described a diverse range of motives, both favoring and opposing their eventual decision to join. Many are well-recognized considerations among nonincarcerated clinical research participants, including a desire for (...) various forms of personal benefit, altruism, and concern about study risks and inconveniences. However, a number of influences seem unique to prisoners. Participants did not report that they were not coerced into enrolling, and they have even been under pressure not to enroll. However, many sought to enroll in order to obtain access to better health care, raising a concern about whether they were unfairly exploited. (shrink)

Intellectual humility, which entails openness to other views and a willingness to listen and engage with them, is crucial for facilitating civil dialogue and progress in debate between opposing sides. In the present research, we tested whether intellectual humility can be reliably detected in discourse and experimentally increased by a prior self-affirmation task. Three-hundred and three participants took part in 116 audio and video-recorded group discussions. Blind to condition, linguists coded participants’ discourse to create an intellectual humility score. As expected, (...) the self-affirmation task increased the coded intellectual humility, as well as participants’ self-rated prosocial affect (e.g., empathy). Unexpectedly, the effect on prosocial affect did not mediate the link between experimental condition and intellectual humility in debate. Self-reported intellectual humility and other personality variables were uncorrelated with expert-coded intellectual humility. Implications of these findings for understanding the social psychological mechanisms underpinning intellectual humility are considered. (shrink)

The target article makes a compelling case for the idea that agents rely on the world for external memory in fast-paced perceptual tasks. As I argue, however, agents also rely on the external environment for computational hardware that helps to keep cognitive computations tractable. Hence the external world provides not only memory for computations involving perceptual system actions, but it provides domain-level actions that figure in cognitive computations as well.

In lieu of an abstract, here is a brief excerpt of the content:Psychiatric Hospitalization—Bridging the Gap Between Respect and ControlPaul P. ChristopherIntroductionThis issue of Narrative Inquiry in Bioethics offers varied and somewhat unique perspectives on the experience of psychiatric hospitalization. This commentary highlights a number of salient themes that emerge from reading these essays and attempts to explore how they relate to the broader academic literature on psychiatric hospitalization, particularly with regard to ethical considerations. In reading these narratives, each several (...) times, I was repeatedly struck by the courage required of the authors, both to share their stories publicly and to endure the challenges that the writing process no doubt demanded of them—revisiting and suspending themselves in deeply emotional and, at times, traumatic experiences in order to share the most compelling narrative. Their hard work clearly paid off—the stories are at once intimate and indelible. Still, in many instances, I found myself wanting to know more; to enter the story and sit with the individual through these events; to ask what they were thinking or feeling in a particular situation; to see and hear the world in which they found themselves. Such is the nature of good story telling—the reader, left with the lingering vision created in his mind, turns over the last page, eagerly hoping for more.Narrative ThemesI. Loss of Autonomy or ControlPerhaps the most notable theme had to do with the loss of control or freedom that followed from hospitalization. On first consideration, it may seem odd that this issue appears so often since patient autonomy constitutes one of the fundamental principles of medical ethics. Only under specific circumstances—e.g., when there is a risk of imminent harm—may autonomy be curtailed, and even then only to the extent that is minimally necessary. Yet, as these narratives highlight, there are a multitude of ways in which psychiatric hospitalization engenders actual or perceived restrictions in freedom (Newton-Howes & Mullen, 2011).Consistent with prior research (Goodwin et al., 1999), many of the authors describe a fear or the actual experience of not being able to leave the hospital freely, even when the admission seems to have been voluntary. For example, one writer worries, “I was so afraid that if I ever went ‘in,’ I would never get ‘out’... I thought I would never taste freedom again... alive.” Another describes:When it came time for my possible discharge they told me that I might not get discharged because I was ‘acting up the previous evenings.’ My anxiety level at this point went through the roof. The only reason I was discharged was because my father knew some politicians. If not [End Page 29] for him I would have been a patient there for perhaps years and my life would have been ruined.A third gives this example: “When I asked to sign the form to leave after three days, [the psychiatrist] told me if I did that she would have me committed.” Another writer fears not having any control of how the psychiatrist might approach the treatment: “... I was totally vulnerable... would the doctors blame me, drug me, shock me, kill me?”Somewhat surprising, however, was the fact that so few of the narratives take issue with the decision to hospitalize. This omission is especially striking in light of the fact that prior reports consistently note that a substantial minority (up to nearly half) of voluntarily admitted patients nevertheless experience their admission as coerced (Bonsack & Borgeat, 2005; Hiday et al., 1997; Katsakou et al., 2010; Rogers et al., 1993; Sheehan & Burns, 2011). Because many of these narrators had been hospitalized more than once, the relative absence of expressed resistance to being hospitalized seems strange, particularly when earlier hospital experiences or their aftermath are often described as negative. For example, one individual characterized the time after being released from the hospital as, “My sense of self was questioned. I felt as if I lost my soul.” Another put it this way:When I got out of the private hospital, I felt like my soul had been ripped out of me. I felt like I had a gaping hole in the center of my body... I felt psychically raped, dazed, and confused.Given these... (shrink)

Background: Therapeutic misconception, the misunderstanding of differences between research and clinical care, is widely prevalent among non-incarcerated trial participants. However, little attention has been paid to its presence among individuals who participate in research while incarcerated. Methods: This study examined the extent to which 72 incarcerated individuals may experience therapeutic misconception about their participation in one of six clinical trials, and its correlation with participant characteristics and potential influences on research participation. Results: On average, participants endorsed 70% of items suggestive (...) of therapeutic misconception. The tendency toward therapeutic misconception was significantly higher among African Americans and Latinos compared to Whites, among older and less educated participants, and among enrollment in a substance-abuse-related trial; it was also correlated with a belief that the trial was the only way to obtain needed treatment. Conclusions: Therapeutic misconception may be particularly high among select incarcerated individuals and is associated with a perceived lack of treatment options. Further examination of therapeutic misconception among incarcerated research participants is needed. (shrink)

The COVID-19 pandemic has presented a global threat to physical and mental health worldwide. Research has highlighted adverse impacts of COVID-19 on wellbeing but has yet to offer insights as to how wellbeing may be protected. Inspired by developments in wellbeing science and guided by our own theoretical framework, we examined the role of various potentially protective factors in a sample of 138 participants from the United Kingdom. Protective factors included physical activity, tragic optimism, gratitude, social support, and nature connectedness. (...) Initial analysis involved the application of one-sample t-tests, which confirmed that wellbeing in the current sample was significantly lower compared to previous samples. Protective factors were observed to account for up to 50% of variance in wellbeing in a hierarchical linear regression that controlled for a range of sociostructural factors including age, gender, and subjective social status, which impact on wellbeing but lie beyond individual control. Gratitude and tragic optimism emerged as significant contributors to the model. Our results identify key psychological attributes that may be harnessed through various positive psychology strategies to mitigate the adverse impacts of hardship and suffering, consistent with an existential positive psychology of suffering.

Inactivation of the Ca2+ extrusion mode of the retinal rod Na- Ca + K exchanger is suggested to be the mechanism that prevents lowering of cytosolic free Ca2+ to < 1 nM when rod cells are saturated for a prolonged time under bright light conditions. Under these conditions, Ca2+ fluxes across disk membranes can contribute significantly to Ca2+ homeostasis in rods.

People can support abstract reasoning by using mental models with spatial simulations. Such models are employed when people represent elements in terms of ordered dimensions (e.g. who is oldest, Tom, Dick, or Harry). We test and find that the process of forming and using such mental models can influence the liking of its elements (e.g. Tom, Dick, or Harry). The presumed internal structure of such models (linear-transitive array of elements), generates variations in processing ease (fluency) when using the model in (...) working memory (see the Symbolic Distance Effect, SDE). Specifically, processing of pairs where elements have larger distances along the order should be easier compared to pairs with smaller distances. Elements from easier pairs should be liked more than elements from difficult pairs (fluency being hedonically positive). Experiment 1 shows that unfamiliar ideographs are liked more when at wider distances and therefore easier to process. Experiment 2 replicates this effect with non-words. Experiment 3 rules out a non-spatial explanation of the effect while Experiments 4 offers a high-powered replication. Experiment 5 shows that the spatial effect spontaneously emerges after learning, even without a task that explicitly focuses on fluency. Experiment 6 employed a shorter array, but yielded no significant results. (shrink)

The practice of paying prisoners to for their participation in research has long been debated, and the controversy is reflected in the differing policies in the U.S. prison systems. Empirical study of financial payments to inmates who enroll in research has focused on whether this practice is coercive. In this study, we examined whether monetary incentives have the potential to be unduly influential among fifty HIV‐positive prisoners. The majority of prisoners surveyed believed that inmates should receive some compensation for their (...) involvement in research and disagreed with statements suggesting that the offer of payment constitutes undue influence. However, a sense of potentially being susceptible to undue influence was significantly higher among participants who had spent a longer time in prison and had less education. Overall, our findings suggest that most prisoners feel that they would be able to make a decision about research enrollment that is not solely based on an offer of monetary payment. (shrink)

Background The use of lengthy, detailed, and complex informed consent forms is of paramount concern in biomedical research as it may not truly promote the rights and interests of research participants. The extent of information in ICFs has been the subject of debates for decades; however, no clear guidance is given. Thus, the objective of this study was to determine the perspectives of research participants about the type and extent of information they need when they are invited to participate in (...) biomedical research. Methods This multi-center, cross-sectional, descriptive survey was conducted at 54 study sites in seven Asia-Pacific countries. A modified Likert-scale questionnaire was used to determine the importance of each element in the ICF among research participants of a biomedical study, with an anchored rating scale from 1 to 5. Results Of the 2484 questionnaires distributed, 2113 were returned. The majority of respondents considered most elements required in the ICF to be ‘moderately important’ to ‘very important’ for their decision making. Major foreseeable risk, direct benefit, and common adverse effects of the intervention were considered to be of most concerned elements in the ICF. Conclusions Research participants would like to be informed of the ICF elements required by ethical guidelines and regulations; however, the importance of each element varied, e.g., risk and benefit associated with research participants were considered to be more important than the general nature or technical details of research. Using a participant-oriented approach by providing more details of the participant-interested elements while avoiding unnecessarily lengthy details of other less important elements would enhance the quality of the ICF.
