The “reproductive suppression hypothesis” states that the strong desire of adolescent girls in our culture to control their weight may reflect the operation of an adaptive mechanism by which ancestral women controlled the timing of their sexual maturation and hence first reproduction, in response to cues about the probable success of reproduction in the current situation. We develop a model based on this hypothesis and explore its behavior and evolutionary and psychological implications across a range of parameter values. We use (...) the process of model development to identify assumptions implicit in the reproductive suppression hypothesis and variables that need to be measured in order to investigate it more fully. In addition, because costs were probably associated with weight control, an important part of this analysis is the specification of situations in which the benefits of adaptive adjustment of the maturation schedule could have outweighed the costs of achieving that adjustment by slowing adolescent weight gain.

We theoretically discuss and empirically show how CEO power based on environmental expertise and formal influence over executives and directors, in the absence and presence of shareholder activism, spurs firms toward greener strategies. Our results support the idea that CEOs with informal power, grounded in expertise, reduce corporate environmental impact and this relationship is amplified when the CEO also enjoys formal power over the board of directors. Additionally, we found that any source of CEO power, whether informal or formal, is (...) a good catalyst for transforming shareholder activism into corporate greening. However, in the absence of such activism, only CEOs’ informal environmental expert power acts as a determinant of firm environmental performance. (shrink)

We present a quantitative model of sex allocation to investigate whether the simple “rules of thumb” suggested by Trivers and Willard (1973) would really maximize numbers of grandchildren in human populations. Using demographic data from the !Kung of southern Africa and the basic assumptions of the Trivers-Willard hypothesis, we calculate expected numbers of grandchildren based on age- and sex-specific reproductive value. Patterns of parental investment that would maximize numbers of expected grandchildren often differ from the Trivers-Willard rules. In particular, the (...) optimum parental behavior is sensitive to population dynamics, type of parental investment, and, most important, relative ages of sons and daughters. It is doubtful whether a parent blindly following the simple Trivers-Willard rules would maximize numbers of expected grandchildren, on average. In addition, we show that sex-specific infanticide will almost never achieve the goal of maximizing expected numbers of grandchildren. (shrink)

Within the psychoanalytic framework, there is a growing body of research and thinking about female development. In addition, there is ongoing research within other areas of psychology, such as developmental psychology and social psychology, which has important implications for an understanding of women's adult development. Often these research findings are not readily available to the analytic community, nor has much of the research been incorporated into a psychoanalytic framework. _Psychoanalysis and Women_ broadens analytic thinking by integrating contemporary literature from psychoanalysis (...) with that of other areas, both within and outside psychology, which has implications for the undertanding of women's development. This literature is conceptualized within a psychoanalytic framework. A basic premise underlying this book is that psychoanalysis needs continuing review and revision in terms of what women and men are about and a continuing focus on whether and how unfounded biases prevent analysts from understanding patients. The present volume considers how sexism and feminism are affecting psychoanalysis and exemplifies how the emerging field of psychoanalysis of women and the issues its existence raises should be conceptualized. It also exemplifies some of the positive contributions that a feminist outlook gives to the study of human behavior and should esxpand the range of hypotheses that we have about people. (shrink)

Children spend more time in school than in any social institution outside the home. And schools probably exert more influence on children’s development and life chances than any environment beyond the home and neighbourhood. The purpose of this book is to document some important ways schools influence children’s development and to describe various models and methods for studying schooling effects. Key features include: Comprehensive Coverage – this is the first book to provide a comprehensive review of what is known about (...) schools as a context for human development. Topical coverage ranges from theoretical foundations to investigative methodologies and from classroom-level influences such as teacher-student relations to broader influences such as school organization and educational policies. Cross-Disciplinary – this volume brings together the divergent perspectives, methods and findings of scholars from a variety of disciplines, among them educational psychology, developmental psychology, school psychology, social psychology, psychiatry, sociology, and educational policy. Chapter Structure – to ensure continuity, chapter authors describe 1) how schooling influences are conceptualized 2) identify their theoretical and methodological approaches 3) discuss the strengths and weaknesses of existing research and 4) highlight implications for future research, practice, and policy. Methodologies – chapters included in the text feature various methodologies including longitudinal studies, hierarchical linear models, experimental and quasi-experimental designs, and mixed methods.

The germ lineage has been studied for a long time because of its crucial role in the propagation and survival of a species. While this lineage, in contrast to the soma, is clearly unique in its totipotent ability to produce a new organism, it has now been found also to have specific features at the cellular level. One feature, a period of transcriptional quiescence in the early germ cell precursors, has been observed in both Drosophila and C. elegans, where it (...) is essential for the formation and the survival of the germline. In addition, there are numerous instances where these early germ cells are reliant on translational regulation, especially in Drosophila. The genes that are important for these two functions, the mechanisms of their action, and studies in vertebrate organisms that reveal similarities as well as some potential differences in early germ cell development are discussed.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 21.1 (2001) 140-144 [Access article in PDF] Book Review Culture and Self: Philosophical and Religious Perspectives, East and West Culture and Self: Philosophical and Religious Perspectives, East and West. Edited by Douglas Allen. Boulder, Colorado: Westview Press, 1997.xv + 184 pp. Inspired perhaps by both deconstructive and constructive impulses, this important collection of nine essays undertakes to challenge the notion, common in both Western and Eastern philosophical (...) and religious traditions, that there exists such a thing as an objective, ahistorical, universal "self." At the same time, the volume as a whole makes a case for the value of a notion of the self that takes account of its cultural and historical situatedness. Douglas Allen's introduction succinctly frames the central claim of this project: While an increasing number of scholars, both Eastern and Western, appreciate the importance of the dialectical relationship between self and culture, and the vital role culture plays in determining the nature of the self, notions of the self as unconditioned by culture, or of the self as influenced by cultural factors that are merely superficial, subjective, and illusory, continue to dominate the religious and philosophical thought of both West and East. Thus it is the aim of these essays to undermine the dominance of those notions, in particular by means of a comparative, [End Page 140] cross-cultural methodology that highlights the existence of differing views of the self, thereby calling into question the dominant monolithic understanding.The essays are divided into four sections. The first part, "Multiple Asian and Western Perspectives," contains two essays in which a number of different Asian views are considered, resulting in analyses that are broad rather than deep. Obviously this approach has its limitations: the observations about the various cultural understandings discussed in each of these essays tend to be somewhat lacking in complexity. However, both essays do a creditable job of presenting the cross-cultural resources available to critique the notion of an enduring, true, objective self, free of sociohistorical determinants.Douglas Allen's essay clearly articulates the somewhat narrow understanding of the self against which his and many of the other views contained in this collection are implicitly positioned, characterizing it as post-Cartesian: autonomous, rational, individual, skeptical, and foundational. In spite of frequent references to the dominance within Eastern thought of the notion of an ahistorical, culturally unconditioned self, and in spite of the richness of views on the eternally unchanging nature of the self to be found, for example, in various forms of Hinduism, it is clearly and explicitly a modern,Western view of the self against which Allen wants to argue. His basic claim, then, is that this modern Western view is itself historically and culturally determined and that, moreover, there are pressing philosophical and political reasons for challenging it. In contrast to this post-Cartesian self, Allen offers four alternative conceptions--the self of the Bhagavad Gita, determined by karma and social position; the "no-self" of Buddhism; the Marxist self, constituted by the economic conditions of production within which it finds itself; and the relational self of much modern Western feminist theory--suggesting that these understandings provide richer views of the self by virtue of taking account of the self's location in history and culture.The target of Alan Roland's essay is not the largely philosophical notion of selfhood considered by Allen, although clearly it builds on that notion. Rather, Roland takes up the self ofWestern psychoanalytic theory in order to ask whether, given the Western assumptions upon which it is based, psychoanalysis can be universally valid. He suggests, in the context of a critical reading of several major psychoanalytic studies of Asian cultures, that psychoanalysis in Asia can be found in three predominant guises, each limited in some important way: evolutionism, which posits the individualist self as the goal of psychological development, thereby dismissing the more relational selves of Asian cultures as developmentally inferior; universalism, which argues for a self that is essentially the same across cultural differences, imposing a single analytical standard on widely diverging...

Higher education, a key driver of women’s empowerment, is still segregated by gender across the world. Agricultural higher education is a field that is male-dominated, even though internationally women play a large role in agricultural production. The purpose of this study was to understand the experience, including challenges and coping strategies, of women from 10 Latin American countries attending an agricultural university in Latin America. The participants were 28 women students with a mean age of 20.9 ± 1.8 years. Following (...) informed consent and assurance of confidentiality, four focus group sessions (one for each year of study with a mean duration of 81 min) were conducted in Spanish. The central question was, “what has been your experience at the university?” Sessions were recorded and transcribed. Thematic coding was performed independently by two teams of researchers (from Latin America and North America), with the resulting schemas combined through mutual discussion. Member checking, auditing, and reflexivity contributed to trustworthiness of the process. Students reported that the personal qualities needed for success included determination, persistence, and self-efficacy. Many described an empowerment process, including increased discipline and self-efficacy from the first to fourth year of study. University life encompassed six themes: university structure and discipline (part of the exosystem), two supportive microsystems (friends and classmates and institutional support) as well as three challenges (academics, peers, and machismo). Cultural influences instantiated in students’ daily experiences included familism, machismo, and religious faith. Students anticipated futures involving further education and contributions to society. We conclude that higher education in agriculture can serve as an effective means of empowering women to feed the world. (shrink)

The development of genomic technologies has seemed almost magical. Excitement about it, both in medicine and among the public, stems from the belief that genomic techniques will illuminate the causes of health and disease, will lead to effective interventions for both rare and common genetic conditions, and will inform reproductive decision‐making. Novel diagnostic tools, however, are often deployed before targeted therapies are developed, tested, or available and before their psychosocial implications are explored. Newer technologies such as prenatal whole exome screening (...) are seen as offering “decisional autonomy” to expectant parents, although such technologies identify information about genetic sequencing that may not have clear meaning. The “therapeutic gap” between the ability to conduct genetic sequencing and the ability to fully understand what the test results mean, much less what treatments to offer, leaves families with complex and unclear information they cannot act upon with confidence during pregnancy. In this essay, we will consider the psychosocial and ethical implications of such assumptions—and of the uncertain information produced by these technologies—for individuals and families and for societal aspects such as medical service usage and demographic inequities.

The growing influence of the late French philosopher Gilles Deleuze in Christian theology is nowhere more apparent than in this impressive work by Daniel Colucciello Barber. Here diaspora is explored not as a sociological phenomenon but as a concept, a composition of thought that reveals the differential nature of the origins of Christianity and its others, religion and secularism. What seems to be at stake in the concept of diaspora, for Barber, is its ability to destabilize the logic of domination (...) that has been identified with much of the history of Christianity, and which arguably carries over into secularism as it is historically conceived.According to Barber’s view of the gospels, the Christian declaration—understood as the injunction to love one’s enemies and imitate divine perfection—provides a liberatory opening out of this logic of dominion and into the construction of new possibilities of human relatedness. How is it, then, that Christianity has historically been allied with .. (shrink)

Client-provider relationships have significant effects on how individuals comprehend their life situation during chronic disease and illness. Yet, little is known about how frontline health care providers (HCPs) influence client’s identity formation through meaning-making with clients such as HIV-positive women living in poverty. This requires ethical consideration of the meanings made between clients and providers about client’s health and well-being, both individually and in the larger society. Health care providers (N = 15) and married women living with HIV (N = (...) 33) in north-central India engaged in separate intensive interviews providing narrative data which were analysed using a conceptual framework crossing Lipsky’s street-level bureaucracy theory (Lipsky 2010) with meaning-making processes. HCPs and women construct meanings of women’s role as caregivers that impact women’s sense of identity, health, and well-being. Findings indicate that despite being well-intentioned, HCPs inadvertently reinforce rigid gender norms and convey that women’s worth is tied to their familial caregiving role. HCPs’ discretionary advocacy may also reinforce societal images of women as incapable and needy, thereby harming them more generally. Attention to the gender-sensitive training of HIV health care providers may assure that discretion is ethically interrogated to promote gender equity and enhance women’s access to social welfare services.

Despite much research on the relationship between awareness and dementia little can be concluded concerning their relationship and the role of other factors. It is likely that studies capture different phenomena of awareness. This study aimed at identifying and delineating such variation by analysing data from three questionnaires obtained during the longitudinal study of awareness in 101 people with early-stage dementia. The data concerned awareness in relation to memory, activities of daily living and socio-emotional function. Significant differences in patterns of (...) discrepancies were obtained. This suggests that the awareness phenomena involved were structurally different; and that, in turn, this may reflect variation in the intrinsic linking between awareness and its ‘object’ . The identification of such differences is necessary so that appropriate methodologies can be applied to the study of awareness in different contexts. (shrink)

Reproduction and immunity are energy intensive, intimately linked processes in most organisms. In women, pregnancy is associated with widespread immunological adaptations that alter immunity to many diseases, whereas, immune dysfunction has emerged as a major cause for infertility in both men and women. Deciphering the molecular bases of this dynamic association is inherently challenging in mammals. This relationship has been traditionally studied in fast‐living, invertebrate species, often in the context of resource allocation between life history traits. More recently, these studies (...) have advanced our understanding of the mechanistic underpinnings of the immunity‐fertility dialogue. Here, we review the molecular connections between reproduction and immunity from the perspective of human pregnancy to mechanistic discoveries in laboratory organisms. We focus particularly on recent invertebrate studies identifying conserved signaling pathways and transcription factors that regulate resource allocation and shape the balance between reproductive status and immune health.

Accumulating evidence for the unique social, behavioral, and physical health benefits of positive emotion and related well-being constructs has led to the development and testing of positive psychological interventions to increase emotional well-being and enhance health promotion and disease prevention. PPIs are specifically aimed at improving emotional well-being and consist of practices such as gratitude, savoring, and acts of kindness. The purpose of this narrative review was to examine the literature on PPIs with a particular focus on positive emotion outcomes. (...) We evaluated the evidence on the effects of PPIs on positive emotion specifically, and discussed the range of evidence regarding the relative responsiveness of emotion measures to PPIs in order to gain a better understanding of the specific emotional pathways through which PPIs influence psychological and physical well-being. We conclude with recommendations for best evaluating effects of PPIs on positive emotion outcomes. (shrink)

We report on the performative score “Sharing Perspectives” from the art/science research collaboration, Experimenting, Experiencing, Reflecting. Sharing Perspectives is developed as a score, inspired by choreography and the postmodern dance form Contact Improvisation, to stage exploration and improvisation, exploring uncertainty, creativity, togetherness, and the relationship between bodies and between bodies and space and artworks. The SP score acts as an experiment in how a brief intervention may affect the way art exhibitions are experienced, exploring how deeper and more sensorial engagement (...) with art may be facilitated, for the benefit of visitors, galleries and artists. Based on questionnaires and qualitative interviews with participants during the Olafur Eliasson exhibition “In Real Life” at the Tate Modern in London in November 2019, we explore how the SP score modulates a playful mode of being, enhancing the experience of a museum art exhibition as a space of transformation and reflection. We find that the SP score encourages curiosity, which allows participants to recognize their habits for art and instead experience art slowly, recognize their comfort zones and move past them. As the score enacts a sensorial and playful approach to the exploration of the exhibition, participants experience a breaking of boundaries between each other, toward the other visitors, as well as to the artworks and the space itself, prompting an experience of being part of the exhibit as a whole. We discuss how the SP score invites a slowness and curiosity that takes on characteristics of play, which can change the participants’ appreciation of an art space. (shrink)

Production and comprehension have long been viewed as inseparable components of language. The study of vision, by contrast, has centered almost exclusively on comprehension. Here we investigate drawing—the most basic form of visual production. How do we convey concepts in visual form, and how does refining this skill, in turn, affect recognition? We developed an online platform for collecting large amounts of drawing and recognition data, and applied a deep convolutional neural network model of visual cortex trained only on natural (...) images to explore the hypothesis that drawing recruits the same abstract feature representations that support natural visual object recognition. Consistent with this hypothesis, higher layers of this model captured the abstract features of both drawings and natural images most important for recognition, and people learning to produce more recognizable drawings of objects exhibited enhanced recognition of those objects. These findings could explain why drawing is so effective for communicating visual concepts, they suggest novel approaches for evaluating and refining conceptual knowledge, and they highlight the potential of deep networks for understanding human learning.

Recent events and advances address the possibility of cloning endangered and extinct species. The ethics of these types of cloning have special considerations, uniquely different from the types of cloning commonly practiced. Cloning of cheetahs may be ethically appropriate, given certain constraints. However, the ethics of cloning extinct species varies; for example, cloning mammoths and Neanderthals is more ethically problematic than conservation cloning, and requires more attention. Cloning Neanderthals in particular is likely unethical and such a project should not be (...) undertaken. It is important to discuss and plan for the constraints necessary to mitigate the harms of conservation and extinct cloning, and it is imperative that scientific and public discourse enlighten and guide actions in the sphere of cloning.

This paper reports and analyzes the perceptions of researchers involved in the EU project LowInputBreed on the ethical challenges facing low input livestock production and how these challenges relate to the ambitions of the research project. The study is based on observations of two workshops; one at the beginning of the project and one at the end. The focus is on identifying common themes across the four species groups involved. The main findings of the study are that from a biological (...) perspective a variety of ways to better meet the needs of low input production exist. However, these solutions share some of the problems regarding animal welfare that also characterizes intensive production systems. The question thus becomes whether these solutions will meet the consumer concerns that lies behind the choice of paying a premium for local, low input products or whether the quality of these products will disappear in the eyes of the consumers.
