This article presents an evaluation framework developed to assess the first-level effects of introducing the Standard Days Method (SDM) in Peru Ministry of Health clinics. Four questions are asked: 1) To what extent do providers routinely achieve SDM service delivery standards? 2) Is the time invested in SDM delivery consistent with program norms? 3) How does SDM delivery compare with delivery of established methods? and 4) How does SDM introduction affect delivery of established methods? A study at 62 clinics demonstrated the framework's usefulness. The Standard Days Method introduction had positive overall effects on the quality of care but provider training needed adjustments. 相似文献

Conventional explanations - lax gun control laws, media violence, single and working parents - do not adequately explain the recent spate of school shootings, and neither does bullying by itself, an explanation recently gaining more traction. A certain type of bullying, however, is revealed as particularly culpable. Many of the recent shootings share a disturbing component: The perpetrators were repeatedly, even relentlessly, accused by "preps and jocks" of being gay. Gay harassment is proposed as a point of departure for understanding the causes of school shootings. When boys who believe on some level that they warrant privilege, are instead harassed, they may feel driven to avenge the "wrong," and re-assert a more dominant, powerful, and victorious masculinity. These circumstances call for a cultural transformation such that "boys will be boys" is no longer used as an alibi for violence. The author presents implications for school-based social work practice, teacher and administrator interventions, as well as other prevention strategies. 相似文献

Online sexual behavior may be more completely explained by integrating a Pull Factor analysis, centering on the characteristics of the Internet that make it an appealing outlet for sexuality (e.g., "Triple A Engine") and a Push Factor analysis, centering on characteristics of the offline world that disallow fulfillment of sexual desires. This new framework is utilized in explaining paraphilic (unconventional) sexualities online. Because paraphilics are members of highly concealable, horizontal and rare sexual minorities, they are pushed online by mainstream society. Online, paraphilics interact with similar others, and through lurking, re-learning and self-disclosing, may become sexually empowered. Clinical ramifications of attainment of positive sexual-social identity via empowerment are discussed, as are possible affects on public policy. 相似文献

The utility of postcensal population estimates depends on the adequate measurement of four major components of demographic change: fertility, mortality, immigration, and emigration. Of the four components, emigration, especially of the foreign-born, has proved the most difficult to gauge. Without "direct" methods (i.e., methods identifying who emigrates and when), demographers have relied on indirect approaches, such as residual methods. Residual estimates, however are sensitive to inaccuracies in their constituent parts and are particularly ill-suited for measuring the emigration of recent arrivals. Here we introduce a new method for estimating foreign-born emigration that takes advantage of the sample design of the Current Population Survey (CPS): repeated interviews of persons in the same housing units over a period of 16 months. Individuals appearing in a first March Supplement to the CPS but not the next include those who died in the intervening year, those who moved within the country, and those who emigrated. We use statistical methods to estimate the proportion of emigrants among those not present in the follow-up interview. Our method produces emigration estimates that are comparable to those from residual methods in the case of longer-term residents (immigrants who arrived more than 10 years ago), but yields higher--and what appear to be more accurate--estimates for recent arrivals. Although somewhat constrained by sample size, we also generate estimates by age, sex, region of birth, and duration of residence in the United States. 相似文献

How does leaving home affect marital timing? An event-history analysis of migration and marriage in Nang Rong, Thailand 总被引:2,自引:0,他引:2
Jampaklay A 《Demography》2006,43(4):711-725
This study examines the effects of migration on marital timing in Thailand between 1984 and 2000 using prospective and retrospective survey data from Nang Rong. In contrast to previous results in the literature, event-history analysis of the longitudinal data reveals a positive, not a negative, effect of lagged migration experience on the likelihood of marriage. The findings also indicate gender differences. Migration's positive impact is independent of other life events for women but is completely "explained" by employment for men. 相似文献

This paper examines factors associated with feeling suicidal in a large sample of urban men in Sydney and Melbourne, aged 18-50, including heterosexual, gay and bisexual men, HIV antibody positive and HIV antibody negative. As in previous research, sexuality (being homosexual or bisexual) was found to be a major predictor of suicidality. The research went some way towards explaining the close relationship between feeling suicidal and sexual orientation. Sexuality interacts with feeling bad in that, once men feel moderately bad/depressed, they are more likely to feel suicidal if they are homosexual or bisexual than if they are heterosexual. In addition, the research found that experience of verbal abuse and physical assault (harassment) increased feeling suicidal for both heterosexual and gay/bisexual men, not just for homosexual men as suggested by previous research, and that social isolation in the form of living alone is a further risk factor. Seeking counseling help and taking sexual risks were also independently associated with feeling suicidal. These actions may result from feeling suicidal rather than the reverse, and their association with feeling suicidal warrants further research. Many of the 46 independent variables examined in the research, including HIV antibody status and closeness to the HIV/ AIDS epidemic, were related to feeling suicidal only through their association with being gay/bisexual. Celibacy and general risk taking were not related to feeling suicidal in this study. 相似文献

This paper explores the contributions made by older women to the community as informal volunteers. It argues that ageing policy is not gender neutral and tends to ignore the contributions made by women outside paid work. As well as being ignored in policy, women's unpaid roles have been denigrated by some feminist commentators, who suggest that these roles subordinate the position of women. The aim of the present paper is to explore the lived experiences of older women in relation to their informal volunteer roles, using role identity theory as a framework. The study utilizes data from a qualitative study using focus group methodology. Findings demonstrate that informal volunteering contributes to the women's identity and gives their lives meaning. These findings suggest that a more positive policy framework around ageing is needed to ensure that the worth of these contributions is recognised. 相似文献

Comments of women engaged in a longitudinal study of urinary leaking from first trimester to 12 months following birth provide the data for this paper. Useful insights into the factors contributing to the maintenance of silence and ways to break the barriers to discussion of urinary incontinence before, during and following pregnancy were revealed. Given the prevalence of 30% of Australian women experiencing urinary leaking following pregnancy, it is imperative that midwives engage in discussion and support prevention of this unwelcome outcome of childbirth. 相似文献

A very small proportion of newborns fail to establish a normal respiratory pattern without some assistance at birth and newborns requiring resuscitative measures at birth should have a skilled practitioner able to provide it. In this small hospital midwives felt unskilled in newborn resuscitation and paediatricians were not always immediately available. A stakeholder group gathered to discuss the problem. A training program was implemented that improved the skills, confidence and support of the attending midwife to resuscitate the newborn effectively. The aim was to improve the outcome for the infant whilst maintaining the mother's choice of birthing in a small local hospital close to family and friends. 相似文献
