Objective: The purpose of this study was to assess the current state of postsecondary educational settings’ outreach to military women who become students postservice. Participants: Data for the present cross-sectional study were obtained from the American College Health Association’s (ACHA) 2011–2014 National College Health Assessment II (NCHA). Methods: Demographic characteristics of the study sample were explored by calculating frequencies and percentages by military service status. Research questions were explored with Fisher’s exact test, maximum likelihood multiple logistic regression, as appropriate. Results: Women service member and veteran students received health information from their university/college less often than women students with no military experience on the following topics: alcohol and other drug use, depression and anxiety, sexual assault and relationship violence prevention, and stress reduction. Conclusions: The findings of this research identified clear gaps in service provision for women student veterans on college campuses and provided some possible models for intervention development. 相似文献

Estimates of pornography use in the United States range widely. We explore the reasons for the variation in such estimates among U.S. adults using data from four different recent nationally representative samples—each of which asked a different type of question about pornography use. We attribute the notable variation in estimates to differences in question wording and answer options, and assert that a survey question asking respondents about their most recent use of pornography minimizes recall bias and is better poised to assess the overall prevalence of pornography in a population than is the more common approach of asking respondents about their historical general-use pattern. When we privileged the most-recent-use approach, survey data from 2014 reveal that 46% of men and 16% of women between the ages of 18 and 39 intentionally viewed pornography in a given week. These numbers are notably higher than most previous population estimates employing different types of questions. The results have ramifications for methods of surveying sensitive self-reported behaviors and for contextualizing scholars’ claims as well as popular conversations about the reach and implications of pornography use in the United States. 相似文献

South Africa is a regional hub for migration on the African continent and is home to a growing documented international migrant community. Foreigners in the country, however, often face violations of their established rights and are the victims of abuse. This paper examines public support for policies that would exclude international migrants from the country. Data from the 2013 South African Social Attitudes Survey, a nationally representative opinion poll (N = 2739) of all adults in the country, are used. This poll found that many South Africans favoured restrictive immigration policies and opposed granting foreigners the same rights as citizens. Multivariate analysis is employed to discern determinants of this opposition. Respondents’ perceptions of the population sizes of foreigners in their communities did not affect support for inclusion. It can be inferred, therefore, that the growth of the immigrant population has not provoked exclusionary attitudes in the country. Rather, results revealed, it is national pride (cultural versus political) and fears about the consequences of immigration that drive such attitudes. Programmes and policies designed to improve public perceptions of how foreigner impact society and the promotion of a nationalism characterised by inclusive multicultural civic patriotism may improve public support for the inclusion of international immigrants. 相似文献

We find a strong positive raw correlation between black exposure to whites in their school district and the prevalence of later mixed-race (black-white) births, consistent with the literature on residential segregation and endogamy. However, that relationship is significantly attenuated by the addition of a few control variables, suggesting that individuals with higher propensities to have mixed-race births are more likely to live in desegregated school districts. We exploit quasi-random variation from court-ordered school desegregation to estimate causal effects of school desegregation on mixed-race childbearing, finding small to moderate effects that are largely statistically insignificant. Because the upward trend across cohorts in mixed-race childbearing was substantial, separating the effects of desegregation plans from secular cohort trends is difficult; results are sensitive to how we specify the cohort trends and to the inclusion of Chicago/Cook County in the sample. The fact that the addition of a few control variables substantially weakens the cross-sectional relationship between lower levels of school segregation and higher rates of mixed-race childbearing suggests that a substantial portion of the observed correlation is likely due to who chooses to live in places with desegregated schools. Researchers should be cautious about interpreting raw correlations between segregation—whether residential or school—and other outcomes as causal. Our results also point to the need to carefully explore specification of cohort effects in quasi-experimental designs for treatments where cumulative exposure is important. 相似文献

The Rural Development Grant operates the Redundant Building Grant which is designed to bring redundant buildings in certain areas into commercial activity. This paper outlines the results of a recent evaluation of the Grant largely based on contacts with more than 400 applicants in nine counties. This survey is used to explore five aspects of rural policy: property development; business performance; job creation; integrated rural development; and aspects of land use planning. 相似文献

Previous research has revealed a significant bivariate relationship between anabolic-androgenic steroid (AAS) use and reduced condom use among adolescent boys. However, to date, no known studies have explored the psychological mechanisms that may explain this relationship. Thus, the current study sought to examine two possible mediators in the association between AAS and condom use: depressive symptoms and substance use. Data were extracted from a nationally representative sample of U.S. adolescents. Participants were 3,780 U.S. high school boys who responded to self-report items assessing a number of health behaviors, including symptoms of depression, substance use, AAS use, and use of condoms during their most recent act of intercourse. Both depression and substance use were significant mediators in the relationship between AAS and condom use. However, when these effects were contrasted, the indirect effect of substance use was significantly stronger in magnitude than the effect of depression. Although AAS use was associated with sexual risk behaviors among adolescent boys, significant variance in this relationship was accounted for by elevated levels of depression and substance use, with substance use demonstrating a particularly salient pathway. 相似文献

This paper uses national longitudinal data and several new empirical strategies to examine the consequences of teenage fatherhood. The key contribution is to compare economic outcomes of young fathers to young men whose partners experienced a miscarriage rather than a live birth. The results suggest that teenage fatherhood decreases years of schooling and the likelihood of receiving a high school diploma and increases general educational development receipt. Teenage fatherhood also appears to increase early marriage and cohabitation, and has mixed short-term effects on several labor market outcomes. 相似文献

In this paper, we use a longitudinal survey that has collected information for 50 years on a large cohort of Wisconsin high
school graduates and their siblings to examine the long term impact of early occupational choice on health status. We find
evidence that beginning a career in a blue collar occupation is correlated with several measures of poor health outcomes at
ages 50–65. Since our dataset includes usually unobserved pre-labor market characteristics, including IQ and childhood health
status, we can show that controlling for these variables is important for many results and suggests a high level of selection
into occupation based on health and ability. We also provide evidence of gender differentials in the association between first
occupation and later health. Then, we replace our basic measure of occupational categories with summary measures of job characteristics
and find that employment at “bad jobs” at the beginning of an individual’s career predicts later health outcomes. Finally,
we use sibling information in the dataset to show that unmeasured family background factors explain a large share of the effects
of occupation on later health. Overall, the evidence points to limited, though heterogeneous, long term effects of health
from blue collar employment. 相似文献

We present data on predictors of treatment outcome for 3200 consecutive referrals to a child and adolescent psychiatry clinic. Using Reliable Change Index (RCI) methodology, we divided children into those who, between intake and discharge, improved, stayed the same, or got worse according to clinician-rated impairment. Most predictors of improvement were related to parent variables (marital status, maternal anxiety, and ethnicity), while those associated with deterioration were tied to child status (extent of psychiatric comorbidity, history of placement in a self-contained classroom, and a prior trial of psychotropic medications). The implications of these findings for data-driven program development, clinic management, treatment planning, and systems of care are discussed. 相似文献

Older adults with multiple pre-existing conditions are admitted to hospitals with acute illnesses and injuries every day. Delirium is not recognized by clinicians across health care settings. With awareness of risk factors and knowledge of delirium, nurses can play a pivotal role in the early identification, treatment, and, most important, prevention of delirium in older adults. Nurses often display a lack of knowledge related to delirium and the complex symptoms that appear differently in the presence of other complicating co-morbid conditions in aging adults. Nurses play a crucial role in keeping patients safe and ensuring optimal outcomes, regardless of the setting. With the growing population of older adults and the expected increases in chronic illness and dementia, delirium is a problem nurses are likely to experience in all practice settings. Knowing what to look for facilitates recognizing the risk and acting early to minimize (or even prevent) delirium. 相似文献
