A basic tenet of reproductive biology is that female mammals are born with a set number of germ cells (oocytes). A new study by Johnson et al. challenges these beliefs by demonstrating that the postnatal mouse ovary contains actively dividing germ cells. These findings have implications for prolonging the reproductive life span of women.  相似文献

The purpose of this study was to examine the influence of having a child diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) on the social and emotional well-being of fathers. While mothers have been carefully scrutinized in ADHD-related literature, fathers have been largely excluded from research designs developed to explore the effects of raising a child with ADHD. Prior research has been primarily based on small, clinically referred and homogenous samples, often without comparisons or controls. This research utilizes a nationally representative sample from the 2001 U.S. National Health Interview Survey to determine differences between fathers of children with ADHD and control fathers and to analyze how the ADHD status of the child, problematic behavior, use of medication, and paternal social support influences fathers’ sense of well-being. This research is also designed to determine whether there are child and family contexts in which the effect of ADHD status on paternal well-being is moderated. Contrary to previous findings about the emotional and social burden associated with raising an ADHD child, few differences between fathers were found.  相似文献

In the last decade, the number of women on corporate boards has increased slightly, but the prevailing minority status of women directors implies that they will continue to face social barriers. While prior research has largely focused on explaining social barriers (e.g., being categorized as an out-group member) to increase diversity and its negative consequences, how boards can avoid these obstacles remains unclear. Stemming from recategorization theory, we examine whether and to what extent board chairperson leadership efficacy and board openness (as mechanisms to avoid out-group bias) enhance the influence of women when they are in the minority in board decision-making. In a sample of 146 Norwegian firms, we found a positive relationship between women minorities and women directors’ contribution to board decision-making. Moreover, we found that this positive impact increases when the board chairperson exercises leadership and the board operates in an atmosphere of openness.  相似文献

Objectives: To determine the socio-demographics, sexual practices, and HIV prevalence of male sex workers (MSWs), transwomen sex workers (TSWs), and their male clients in Lima, Peru. Methods: Following ethnographic mapping of sex work venues, the authors revisited randomly selected venues to survey MSWs, TSWs and their clients. Results: MSWs and TSW clients are more educated than MSW clients and TSWs. Only 50% of TSW clients have received HIV testing. Self-reported HIV positivity is highest among MSW clients and TSWs. Conclusion: Notable differences exist between MSWs and TSWs and their clients that can affect the health of these groups and warrant intervention.  相似文献

We revisit Hakim's influential preference theory to demonstrate how it is both reflective of postfeminism and generative of its values and practices. We differentiate between two interpretations of postfeminism — first a surface‐level ‘successful but obsolete’ version articulated by Hakim and second a multilayered account of postfeminism as a discursive formation connected to a set of discourses around gender, feminism and femininity. Drawing on this latter version we make visible the embeddedness of postfeminism in preference theory, highlighting its connection to the creation of a new postfeminist subjectivity based on an agentic and ‘choosing’ femininity. We show how a consideration of preference theory in terms of the emergence and constitution of ‘the female chooser’ opens up aspects of Hakim's thesis that to date have been overlooked. In addition, our postfeminist reading of preference theory draws out aspects of Hakim's account that she herself understated. Specifically, within a contemporary context where equivalent priority is afforded to wage work and care work, it is Hakim's ‘adaptive’ woman who exemplifies the new postfeminist subject required to perform well simultaneously in both the work and domestic domains.  相似文献

ABSTRACT

Based on person–organization fit theory, this article moves beyond theories of motivation and social exchange relationships that have often been used in commitment literature. This article contributes to understanding perceptions of organizational culture (OC) and affective commitment (AC) through perceptions of a learning organization (LO). Such understanding helps to tackle current commitment issues in Malaysia through strategic human resources development (HRD) planning and deploying organization development activities. We examined: (a) the extent to which organizations with an embraced LO mediated OC and AC, (b) the most influential component of OC in promoting employee AC, and (c) the most important component of LO for influencing OC and AC. We obtained 516 respondents (64.5% response rate) in selected Malaysian private organizations. It was concluded that LO mediated the relationship between OC and AC. Respect for people was an influential factor of OC for AC, while empowerment played a significant role in LO culture mediating the relationship between OC and AC. HRD practitioners should strategically plan organizational activities, norms, and policies that promote organizational learning processes and a learning culture to enhance AC.  相似文献

This paper presents the findings of a qualitative study with children affected by sexual abuse who had recently completed a therapeutic intervention (N = 12) and their carers (N = 17). Four themes emerged from the thematic analysis that influenced participants' satisfaction with the service: the attribution of the child's recovery to the therapeutic support received; the therapeutic relationship between the child and practitioner; children's recollection of important aspects of the intervention and the relationship between the carer and the child's practitioner. The findings indicate that the process elements of therapeutic support, including the development of strong relationships and allowing children choice and control, are as important as the content.  相似文献

Problem

Clinical practice guidelines indicate that over 80% of women with a previous caesarean should be offered a planned vaginal birth after caesarean (VBAC), however only one third of eligible women choose to plan a VBAC. To support informed choices for birth after caesarean, it is necessary to understand the factors that influence women’s decision-making.

Aim

The goal of this study was to explore attitudes towards and experiences with decision-making for mode of delivery after caesarean from the perspectives of Canadian women.

Methods

In-depth, semi-structured interviews were conducted with 23 women eligible for VBAC in three rural and two urban communities in British Columbia, Canada, during summer 2015. Constructivist grounded theory informed iterative data collection and analysis.

Findings

Women’s decision-making experiences were a process of “seeking control in the midst of uncertainty.” Women formed early preferences for mode of delivery after their primary caesareans and engaged in careful deliberation during their inter-pregnancy interval, consisting of: reflecting on their birth, clarifying their values, becoming informed, considering the feasibility of options, deliberating with the care team, and making an actual choice. Women struggled to make trade-offs between having a healthy baby and social attributes of delivery, such as uninterrupted bonding with their newborn.

Conclusions

Women begin decision-making for birth after caesarean earlier than previously reported and their choices are influenced by personal experience and psychosocial concerns. Future interventions to support choice of mode of delivery should begin early after the primary caesarean, to reflect when women begin to form preferences.  相似文献
