In many species the mutation rate is higher in males than in females, a phenomenon denoted as male mutation bias. This is often observed in animals where males produce many more sperm than females produce eggs, and is thought to result from differences in the number of replication‐associated mutations accumulated in each sex. Thus, studies of male mutation bias have the capacity to reveal information about the replication‐dependent or replication‐independent nature of different mutations. The availability of whole genome sequences for (...) many species, as well as for multiple individuals within a species, has opened the door to studying factors, both sequence‐specific and those acting on the genome globally, that affect differences in mutation rates between males and females. Here, we assess the advantages that genomic sequences provide for studies of male mutation bias and general mutation mechanisms, discuss major challenges left unresolved, and speculate about the direction of future studies.

The pregnancy compensation hypothesis provides a mechanistic explanation for the evolution of sex differences in immune system functioning, the excess of women experiencing autoimmune disease, and why this is observed only in industrialized nations; none of which can be explained by the staying alive theory, as proposed by the authors of the target article.

BackgroundCommentators believe that the ethical decision-making climate is instrumental in enhancing interprofessional collaboration in intensive care units. Our aim was twofold: to determine the perception of the ethical climate, levels of moral distress, and intention to leave one's job among nurses and physicians, and between the different ICU types and determine the association between the ethical climate, moral distress, and intention to leave.MethodsWe performed a cross-sectional questionnaire study between May 2021 and August 2021 involving 206 nurses and physicians in a (...) large urban academic hospital. We used the validated Ethical Decision-Making Climate Questionnaire and the Measure of Moral Distress for Healthcare Professionals tools and asked respondents their intention to leave their jobs. We also made comparisons between the different ICU types. We used Pearson's correlation coefficient to identify statistically significant associations between the Ethical Climate, Moral Distress, and Intention to Leave.ResultsNurses perceived the ethical climate for decision-making as less favorable than physicians. They also had significantly greater levels of moral distress and higher intention to leave their job rates than physicians. Regarding the ICU types, the Neonatal/pediatric unit had a significantly higher overall ethical climate score than the Medical and Surgical units and also demonstrated lower moral distress scores and lower “intention to leave” scores compared with both the Medical and Surgical units. The ethical climate and moral distress scores were negatively correlated ; moral distress and "intention to leave" was positively correlated ; and ethical climate and “intention to leave” were negatively correlated.ConclusionsSignificant differences exist in the perception of the ethical climate, levels of moral distress, and intention to leave between nurses and physicians and between the different ICU types. Inspecting the individual factors of the ethical climate and moral distress tools can help hospital leadership target organizational factors that improve interprofessional collaboration, lessening moral distress, decreasing turnover, and improved patient care.

The presence of fetal cells has been associated with both positive and negative effects on maternal health. These paradoxical effects may be due to the fact that maternal and offspring fitness interests are aligned in certain domains and conflicting in others, which may have led to the evolution of fetal microchimeric phenotypes that can manipulate maternal tissues. We use cooperation and conflict theory to generate testable predictions about domains in which fetal microchimerism may enhance maternal health and those in which (...) it may be detrimental. This framework suggests that fetal cells may function both to contribute to maternal somatic maintenance (e.g. wound healing) and to manipulate maternal physiology to enhance resource transmission to offspring (e.g. enhancing milk production). In this review, we use an evolutionary framework to make testable predictions about the role of fetal microchimerism in lactation, thyroid function, autoimmune disease, cancer and maternal emotional, and psychological health.Also watch the Video Abstract.

Esta obra se concentra en cuatro temas cruciales de la formación de docentes, tanto antes como durante el servicio y en la enseñanza en diferentes áreas y niveles educativos. En primer lugar, se aborda el asunto de las creencias que los docentes tienen sobre el proceso educativo, las cuales parecen influir en la práctica profesional que estos desarrollan y, por lo tanto, deberían recibir la atención explícita de los procesos de formación de docentes que deseen promover prácticas específicas. El segundo (...) tema de la obra es la relación entre la formación de docentes y la política pública que la rige. En particular, se analizan las reformas curriculares implementadas por varias licenciaturas en universidades privadas colombianas, en respuesta a reformas a la normatividad sobre las condiciones de calidad que a las que deben ajustarse todas las licenciaturas del país. El tercer tema analizado es en qué medida los docentes en educación superior van más allá del dominio de su saber disciplinar atribuyendo importancia a la pedagogía, la didáctica y la práctica reflexiva en su propia práctica docente. Finalmente, se discuten aspectos de la formación de docentes relacionados con los procesos vividos y los retos encontrados por los docentes al entrar en la profesión, su socialización en la comunidad docente, sus identidades como maestros y su motivación para ser docentes. Vale la pena señalar que las contribuciones a este libro comparten el uso de metodologías cualitativas y presentan los resultados de historias de vida, entrevistas, observaciones, y análisis documentales, entre otros.

In this paper, I take up the challenge that political activism runs the risk of generating abstract freedoms for oppressed subjects and neglecting the effects of oppression on the development of subjectivity. I argue that a political activism in concert with a companion ethics of advocacy and listening is best positioned to improve the political and economic conditions of individuals as well as ensure that they are able to realize their freedom in meaningful action. In this paper I distinguish political (...) emancipation from human emancipation using the political and ethical writings of Simone de Beauvoir. I then argue that a feminist ethics of advocacy and listening can serve the project of human emancipation as emancipatory advocacy. I then return to Beauvoir to illuminate the dynamics of privilege, risk, and ambiguity in emancipatory advocacy through her own activism and advocacy in the case of Djamila Boupacha and Algerian independence.

In this study, we investigated whether differences in the experience of regret may be a potential explanation for damaging behaviours associated with psychopathy and criminal offending. Participants were incarcerated offenders (n = 60) and non-incarcerated controls (n = 20). Psychopathic traits were characterised with the Psychopathic Checklist: Screening Version. Regret was assessed by responses to outcomes on a simulated gambling task. Incarcerated offenders experienced a reduced sense of regret as compared to non-incarcerated controls. We obtained some evidence that specific psychopathic (...) factors and facets could differentially relate to the experience and use of emotions. Our data provide initial evidence of important associations between negative emotions and decision behaviour in the context of criminal offending. (shrink)

This research illuminates struggles over cultural definitions of femininity by examining how cultural gatekeepers respond to girls' vocal critique of inauthentic media images. Interviews with 10 editors at two national girls' magazine organizations provide a rare glimpse into their contradictory responses to requests for depicting “real girls.” Editors legitimate and share in the critique, claiming they should change images but cannot. In these accounts, they reveal struggles over altering narrow images of femininity at the organizational and institutional levels. Editors also (...) delegitimate girls' critique as misguided by calling on the media organizations' norms and schemas about how the reader is supposed to understand the images. Paradoxically, here, editors claim that they can change images but should not. Ultimately, the power of girls' resistance is tempered, as both sets of responses lead to the girls' critique being inefficacious in redefining femininity. The study contributes to an understanding of how femininity-defining cultural institutions operate to create and sustain gender stratification. (shrink)

Within the growing developmental literature on children's testimonial learning, the emphasis placed on children's evaluations of testimonial evidence has shielded from view some of the more collaborative dimensions of testimonial learning. Drawing on recent philosophical work on testimony and interpersonal trust, we argue for an alternative way of conceptualizing the social nature of testimonial learning. On this alternative, some testimonial learning is the result of a jointly collaborative epistemic activity, an activity that aims at the epistemic goal of true belief, (...) but that does so by means of an irreducibly social process.

This essay brings psychoanalytic theory on trauma together with film and television criticism on rape narrative in an analysis of Michael Coel’s 2020 series I May Destroy You. Beyond the limited carceral framework of the police procedural, which dislocates the act of violence from the survivor’s history and context, Coel’s polyvalent, looping narrative metabolizes rape television’s forms and genres in order to stage and restage both trauma and genre again and anew. Contesting common conceptions of vulnerability and susceptibility that prefigure (...) a violent breach of autonomy, Coel’s series and her interviews about it invite an ethics of looking that embraces a curiosity in the unknowable and untreatable kernel of subjective experience and defies and resists a policing of the survivor’s thoughts and emotions. By emphasizing and exploring what psychoanalysis calls the “afterwardness” of trauma, Coel foregrounds her main character’s subjectivity prior to her victimization, widens the sphere of consequence beyond the victim and criminal justice system to the survivor’s larger community, and entreats that community to preserve a space for her to look and look again at everything, without judgment.

In this essay I argue that commodity consumption is to the regime of political capitalism at the turn of this century what Michel Foucault claimed for discourses of sexuality in the bio-political state. If I am right, then understanding contemporary subjectivities requires granting greater political credence to practices of commodity consumption than they generally receive and a correlative paradigm shift in our notion of desire - from discourses of sexuality to erotics of appetite. But whatever 'ethical substance' we focus upon (...) when we analyze our contemporary situation I think we must give greater consideration to practices of individual conduct. We must grant due attention to the uses to which our bodies, skills and resources are put, and to our active as well as passive participation in that usage, because our everyday conduct may be the missing link between our professed convictions and our actual political prospects. Key Words: capitalism • commodity consumption • conduct • democracy • ethics • Michel Foucault • freedom • politics • sexuality. (shrink)

Deliberative democratic theory as developed by Jürgen Habermas struggles in its applicability to particular political communities due to its ideality and abstractness. However, philosophers who level this critique against deliberative theory also find in it resources for addressing the legitimacy of live political discourse as it aims towards rationality. This paper takes up the procedural requirement that legitimacy is provided through, as Seyla Benhabib writes, “the free and unconstrained public deliberation of all about matters of common concern.” Using deliberative theory, (...) I develop a test for judging the success and failure of public discourse, and apply this test to political debates in the United States in 2011–2012 concerning women’s lives: the Violence Against Women Act, the birth control mandate in the Affordable Care Act, the censuring of two female legislators in Michigan, and the congressional testimony of a fetus in Ohio. A central piece of my argument is that the knowledge produced about women’s interests and about women’s epistemic authority undermines their participation in public discourse, thus challenging the legitimacy of the decisions resulting from these instances of deliberation.

What is the nature of children's trust in testimony? Is it based primarily on evidential correlations between statements and facts, as stated by Hume, or does it derive from an interest in the trustworthiness of particular speakers? In this essay, we explore these questions in an effort to understand the developmental course and cognitive bases of children's extensive reliance on testimony. Recent work shows that, from an early age, children monitor the reliability of particular informants, differentiate between those who make (...) true and false claims and keep that differential accuracy in mind when evaluating new information from these people. We argue that this selective trust is likely to involve the mentalistic appraisal of speakers rather than surface generalizations of their behavior. Finally, we review the significance of children's deference to adult authority on issues of naming and categorization. In addition to challenging a purely inductive account of trust, these and other findings reflect a potentially rich set of tools brought by children to the task of learning from people's testimony.

Using psychosocial acceleration theory, this multimethod, multi-reporter study examines how early adversity adaptively shapes the development of a self-regulation construct: effortful control. Investigation of links between early life harshness and unpredictability and the development of effortful control could facilitate a nuanced understanding of early environmental effects on cognitive and social development. Using the Building Strong Families national longitudinal data set, aspects of early environmental harshness and early environmental unpredictability were tested as unique predictors of effortful control at age 3 using (...) multiple regression. Early harshness variables were financial harshness, mothers’ and fathers’ observed parenting, mothers’ and fathers’ reported use of harsh discipline, and harsh neighborhood conditions. Early unpredictability was measured by number of paternal transitions. Cues of harshness, specifically observed unresponsive parenting, observed harsh parenting, and neighborhood harshness, did significantly negatively predict effortful control. Paternal transitions also significantly predicted effortful control, but in the opposite (i.e., positive) direction. The results corroborate previous research linking quality of parenting to the development of children’s effortful control and place it within an evolutionary-developmental theoretical framework. Further, the results suggest that neighborhood harshness may also direct developmental trajectories of effortful control in young children, though the mechanisms through which this occurs are still unclear. This is the first study to explicitly investigate effortful control development in early childhood within the harshness and unpredictability framework. (shrink)

Intelligible speakers achieve specific vocal tract constrictions in rapid sequence. These constrictions are associated in theory with speech motor goals. Adult-focused models of speech production assume that discrete phonological representations, sequenced into word-length plans for output, define these goals. This assumption introduces a serial order problem for speech. It is also at odds with children's speech. In particular, child phonology and timing control suggest holistic speech plans, and so the hypothesis of whole word production. This hypothesis solves the serial order (...) problem by avoiding it. When the same solution is applied to adult speech the problem becomes how to explain the development of highly intelligible speech. This is the problem addressed here. A modeling approach is used to demonstrate how perceptual-motor units of production emerge over developmental time with the perceptual-motor integration of holistic speech plans that are also phonological representations; the specific argument is that perceptual-motor units are a product of trajectories (nearly) crossing in motor space. The model, which focuses on the integration process, defines the perceptual-motor map as a set of linked pairs of experienced perceptual and motor trajectories. The trajectories are time-based excursions through speaker-defined perceptual and motor spaces. By hypothesis, junctures appear where motor trajectories near or overlap one another in motor space when the shared (or extremely similar) articulatory configurations in these regions are exploited to combine perceptually-linked motor paths along different trajectories. Junctures form in clusters in motor space. These clusters, along with their corresponding (linked) perceptual points, represent perceptual-motor units of production, albeit at the level of speech motor control only. The units serve as pivots in motor space during speaking; they are points of transition from one motor trajectory to another along perceptually-linked paths that are selected to produce best approximations of whole word targets.

Initially identified as a key phosphoinositide that controls membrane trafficking at the Golgi complex, phosphatidylinositol‐4‐phosphate (PI4P) has emerged as a key molecule in the regulation of a diverse array of cellular functions. In this review we will discuss selected examples of the findings that in the last few years have significantly increased our awareness of the regulation and roles of PI4P in the Golgi complex and beyond. We will also highlight the role of PI4P in infection and cancer. We believe (...) that, with the increasing number of regulators and effectors of PI4P identified, the time is ripe for a more integrated approach of study. A first step in this direction is the delineation of PI4P‐centered molecular networks that we provide using data from low and high throughput studies in yeast and mammals. (shrink)

The end of the Republic and the early Augustan period witnessed several changes in the size and drape of the "elite" toga. The implementation of the toga, with its capacity to change, demonstrates elite anxiety over their rank and status and the ways in which elements of adornment could be used to assert, defend, and manipulate identities in response to changing political and social circumstances. As a tool for maintaining order by demonstrating legitimacy, the changeable toga was adopted by Augustus (...) as he and members of Rome's elite each negotiated his own place in the Roman world.

The authors examine the claim that the most recent cohort of U.S. women is reluctant to identify as feminist although it has egalitarian gender attitudes. Using two national surveys, they show that the most recent generation is no less likely than prior cohorts to identify as feminist. However, Baby Bust women are less apt to identify as feminist than are older women, once background characteristics and attitudes related to feminist identification are controlled. Analyses suggest this reluctance is not due to (...) an aversion to feminism but reflects the “off” timing of the feminist movement in the lives of Baby Bust women. The authors also find important differences among cohorts in the correlates of feminist identity. Most notably, the relationships of political ideology and gender attitudes to feminist identity are stronger among Baby Boom women, who came of age during the feminist movement’s second wave, than among older and younger women.

Die Ansicht, dass Leibniz urn 1700 oder einige Zeit danach ein überzeugter Idealist war oder wurde, der allein an die Realität der Geister und ihrer Ideen glaubte, hält sich merkwürdigerweise in der neueren Sekundärliteratur. In diesem Beitrag beurteilen wir die Textgrundlage für diese Behauptung nach von uns für solide gehaltenen Kriterien einer historischen Interpretation, wobei sich die Behauptung unserer Ansicht nach als unzureichend erweist. Obwohl Leibniz zur Überzeugung gelangt war, dass wirkliche "Atome" der Natur keine Ausdehnung hätten, war er sein (...) Leben hindurch auf die Geistesunabhängigkeit lebender Kreaturen festgelegt, in der Art, die eindeutig Idealismus ausschließt. Wir versuchen, die tieferen Gründe für die Beharrlichkeit der idealistischen Sichtweise, trotz ihrer textlichen und konzeptualen Schwierigkeiten, aufzudecken, indem wir sie letztlich in den ahistorischen Präferenzen der Kommentatoren lokalisieren.
