Recent years have seen African militaries attempt coups in virtually every geographic region, from Egypt to Lesotho and Guinea to Madagascar. They have targeted established democracies, infantile democratic experiments, increasingly authoritarian executives, power vacuums brought on by leader death, and—most recently in Burundi—leaders attempting to circumvent constitutional limitations on their tenure. These continuing acts perpetrated against regimes with such varied backdrops suggests that coups still afflict a wide range of states and remain a continuing threat to leader tenure. This is in contrast to the African Union’s emphasis on curbing the practice. This paper explores the African Union’s effectiveness to combat military coups, primarily focusing on the potential for sanctions to act as a deterrent to would-be coup plotters. The paper also considers potential limitations on the African Union’s (AU’s) ability to project power against certain states. Analyses for the years 1950–2014 indicate Africa has in fact witnessed a meaningful decline in coup activity, an impact even more pronounced than the end of the Cold War. Results also indicate that the AU’s effectiveness in deterring coups is not constrained in cases where they are expected to lack leverage. 相似文献

The prevalence of childhood and adolescent obesity has tripled in the past three decades. This increase has been accompanied
by a dramatic rise in obesity-related health complications among American youth. Thus, many obese youth are now experiencing
illnesses that will threaten their life expectancy in the absence of significant weight loss. Despite these concerns, a relatively
modest body of research has focused on the treatment of adolescent obesity. Results from trials investigating the efficacy
of behavioral and pharmacological treatments, like studies of these interventions with adults, suggest that individuals typically
lose 5–10% of their initial weight. Unfortunately, weight regain is common. Given the increase in the number of obese adolescents,
coupled with the modest results from more conservative treatment approaches, it is not surprising that bariatric surgery for
adolescents who suffer from extreme obesity has grown in popularity. The weight losses after surgery are impressive and many
adolescents, like adults, experience significant improvements in their physical and mental health postoperatively. However,
only a small fraction of adolescents and adults who are heavy enough for bariatric surgery present for surgical treatment.
Among those who undergo surgery, a significant minority appear to struggle with a number of behavioral and psychosocial issues
that threaten their lifelong success. With all of this in mind, the current obesity problem in the United States and other
Westernized countries likely will present a significant challenge to both current and future medical and mental health professionals
who work with adolescents and young adults. 相似文献

Early pubertal timing (PT) increases the risk of adolescent delinquency, whereas late development reduces this risk; however, the mechanisms explaining PT effects on delinquency remain elusive. Theoretically, the PT–delinquency relationship is as a result of changes in parental supervision, peer affiliations, and body-image perceptions or is a spurious reflection of early life risk factors. Using intergenerational data from the Millennium Cohort Study, a prospective sample of children followed from infancy to age 14 years in the United Kingdom (N = 11,556 parent–child pairs), we find that for both boys and girls, early PT is associated with heightened risks of delinquency, relative to on-time puberty, whereas late PT is associated with lower risks, even after controlling for a large share of childhood confounders. Mediation test results indicate that changes in parental supervision, peer affiliations, and body-image perceptions from ages 11 to 14 partly account for associations between off-time PT and delinquency. Our findings are most consistent with criminological theories in which the psychosocial, familial, and peer group changes that accompany off-time pubertal development are emphasized. Changes in peer substance use, in particular, were the primary explanatory factor for the relationships between early and late PT and delinquency, for both boys and girls. 相似文献

The complexity of the sexual harassment language of the #MeToo movement creates discontinuities that may muddy intended communications. Yet understanding this language provides a fuller picture of the experiences that women face. Gender harassment has persisted in the workplace despite long-standing antidiscrimination policies, perhaps because of a universal failure to recognize all forms of it—some of which are more pervasive and common than sexual abuse. This article considers the ability of the academy to affect sexual harassment in public administration. It discusses the implications of gender harassment, the least recognized form of sexual harassment, and makes recommendations for overcoming gender barriers in the academy and in practice. Evidence-based guidance for advancing women in the academy may create more equitable and just spaces for teaching and learning. Public administration classrooms and scholarship represent critical opportunities to recognize patterns of organizational practice and systematically redress gender harassment in the workplace. 相似文献

This study examines women's managerial experiences in leadership roles and reflects on their career needs. Women's career needs are understood by applying the Kaleidoscope Career Model (KCM), which is yet to be widely explored in public sector settings. The KCM recognizes the interplay of multiple experiences that shape the career development of women in the workforce. Using 21 in-depth interviews with women municipal government leaders in the United States; we find that while all three parameters of the KCM model are relevant for women public managers, the need for balance is overwhelmingly evident for women across all generations. Further, we demonstrate how the relationality of women public managers and the interplay of personal and professional needs drive their career goals. The findings from this study are relevant to human resource development policies and practices that consider generational differences into account. Work-life balance needs are relevant for women across all generations (Baby Boomer, Generation X, and Generation Y), and organizations play a vital role in mitigating the burden for women managers. Women public managers' need for balance dominates across generations over the need for challenge and authenticity. Human resource management programs should consider policies and programs that are responsive to the specific needs of women across different generations. Women managers from Generation X and Baby Boomer generational cohorts express interest in leaving their current position or look forward to retirement in the future. 相似文献

ABSTRACT This paper reports on a sample of 16,953 male and 7,783 female convicts transported to Van Diemen’s Land between 1818 and 1853 whose life courses have been reconstructed as much as possible from cradle to grave to explore the effects of critical life stages and the impact of a shared exposure to a stress regime of penal servitude, forced labour and exile. It uses survival and family formation of a lineage as the key measures of life outcomes. It finds that male convicts, while not producing many descendants because of sex imbalances, did well biologically out of being transported, while female convicts, entering servitude under a greater burden of previous abuse and deprivation, continued to suffer a severe gender penalty in survival and significant secondary infertility after sentence. Early life effects from the social environment, or crime economy, into which men were born remained remarkably persistent, while the previous history of prostitution and/or alcohol abuse dramatically shortened the lives of women. These were the embodied effects, over generations, of structural violence against women in the most deprived and dangerous neighbourhoods of from the late-eighteenth century through to the 1840s in Great Britain and Ireland, and transported with them to the Australian colonies. 相似文献
