ABSTRACT

Sexual minority youth face multiple challenges, yet research regarding evidence-informed practice strategies for this population is limited. This study describes the pilot efforts of Strengths First, the first strengths-based intervention created specifically to promote self-esteem and self-efficacy among multiethnic sexual minority youth. A pretest–posttest design was used to gather preliminary data from program participants (n = 162) about the potential effectiveness of the program during a 2-year period that ranged from the inception of the program in June 2008 to September 2010. Significant increases in self-esteem and self-efficacy were found. Implications for social service research and practice are discussed.  相似文献

We conduct a cross‐national analysis to test the dependency theory hypothesis that International Monetary Fund structural adjustment adversely impacts maternal mortality in sub‐Saharan Africa. We use generalized least square random effects regression models and modified two‐step Heckman models that correct for endogeneity using data on 37 African nations with up to four time points (1990, 1995, 2000, and 2005). We find support for our hypothesis, which indicates that sub‐Saharan African nations that receive an International Monetary Fund structural adjustment loan tend to have higher levels of maternal mortality than sub‐Saharan African nations that do not receive such a loan. This finding remains stable when controlling for endogeneity related to whether or not a sub‐Saharan African nation receives a structural adjustment loan. We conclude by discussing the theoretical implications, methodological implications, policy suggestions, and possible directions for future research.  相似文献

Outstanding political leaders are frequently called upon to make high-stakes decisions. Because of the controversial and highly visible nature of these issues, they often face intense criticism. Leaders' responses to criticisms not only affect follower reactions, but also the successful resolution of the contested issue. The present study examines leader and follower reactions to different types of criticisms. A historiometric approach was used to examine biographies containing criticisms of 120 world leaders and to explore leader behaviors in response to criticisms. Specifically, leader response strategies and their success in terms of follower reactions and resolution of the criticism were examined. The results indicated that collaborative or confrontational leader response strategies proved most effective in terms of the leader's ability to continue forward with a particular agenda item and to gather support of those around him or her. Conversely, avoidant, diverting attention, and persuasive response strategies proved less effective.  相似文献

Use of Acute Toxicity to Estimate Carcinogenic Risk   总被引:1,自引:0,他引:1  
Data on the effects of human exposure to carcinogens are limited, so that estimation of the risks of carcinogens must be obtained indirectly. Current risk estimates are generally based on lifetime animal bioassays which are expensive and which take more than two years to complete. We here show how data on acute toxicity can be used to make a preliminary estimate of carcinogenic risk and give an idea of the uncertainty in that risk estimate. The estimates obtained are biased upwards, and so are useful for setting interim standards and determining whether further study is worthwhile. A general scheme which incorporates the use of such estimates is outlined, and it is shown by example how adoption of the procedures suggested could have prevented regulatory hiatus in the past.  相似文献

Four previously published data sets are used to reconsider whether the reputational method identifies pyramidal community power structures while non-reputational methods identify non-pyramidal power structures. Further considered is whether results are methodological artifacts. The reanalysis suggests that the reputational method tends to locate pyramidal and non-pyramidal power structures. The data do not indicate methods' artifacts.  相似文献

This study assessed the construct validities and the relationships between Optimism [21], Hope [27], Self-Efficacy [18], and Locus of Control [12]. The validities and relationships between these scales were examined not only because they are to some degree rival constructs but also because there is an outstanding theoretical question in the literature of whether each of these variables is a state or trait variable or both. Synder' Hope scale was the "know marker" trait-state scale in this study. Data were obtained on all scales from 78 at-risk university students and 22 regular (or normal) students, as all scales either make claims about or have existing data on these two different types of subjects. Other background data were also collected. A Manova on the 13 variables for which data were obtained found significant profile differences between the two groups of subjects as theory and the literature predicted at the 0.01 level. The trait-state two factor structure of Synder's Hope scale was found except the structure was orthogonal in at-risk students as opposed to the oblique structure Synder found in normals. The same strong results were obtained for Schiever and Carver's Optimism scale which additionally resolved an outstanding interpetability issue with this scale. Hypothesized factor structures were not obtained for the self-efficacy or the locus of control scales and both scales best fit the trait-sate model, which contradicts Bandura's and other prevailing view of these two variables, but supports the results found by Bandalos et al. [2].  相似文献

A key theme in the bereavement literature is the recognition that every grief experience is unique and dependent on many variables, such as the circumstances of the death, characteristics of the bereaved individual, their relationship with the deceased, the provision and availability of support, and a myriad of sociocultural factors. Concurrently, there are corresponding efforts to define "normal" grief and delineate it from "complicated" grief experiences. The discord between these two potentially opposing statements remains a paradox evident within the three major tensions within the thanatological literature--the dominance of grief theories, the medicalization of grief, and the efficacy of grief interventions. Three recommendations for moving beyond the paradox are discussed--the provision of improved grief education for service providers, the bereaved, and the wider community; the conduct of research that emphasizes the context of grief and is relevant to service provision; and the examination of current grief interventions.  相似文献

领导人不一定非得擅长公众讲演、拥有卓越的战略头脑, 并具有与追随者打成一片的能力 人们通常认为,好的领导人必须富有激情。他们必须擅 长公众讲演,拥有卓越的战略头脑,并具有与追随者 打成一片的能力。但《你必须知道的一件事》一书的 作者马库斯·白金汉(Marcus Buckingham)却坚持认为,事实 并非如此。领导人不一定非得表现出这些素质,但领导人必须 有能力让追随者明白:自己的服务对象是谁,他们凭借什么击 败竞争对手,如何衡量他们的绩效,以及哪些行动会帮助他们 实现自己的目标。  相似文献

This study explored perceptions of partner body image preferences and symptoms of disordered eating in gay and heterosexual men. Participants were male college students (= 201; M age = 20.46), and over one third identified as gay. We compared discrepancies between participants’ current and ideal body type and participants’ current body type and the body type they believed they should have to attract a dating partner. For gay men, the discrepancy between their current body and the body they believed they should have to attract a dating partner was significantly greater than the discrepancy between their current and ideal body types. In gay and heterosexual men, the discrepancy between current body and the body they believed they should have to attract a dating partner predicted eating, shape, and weight concern. Results suggest that perceptions of partner body image preferences may contribute to eating disorder pathology in men.  相似文献
