Body mass has been neglected as a possible predictor of suicidal behavior. The present investigation explores the association between body mass index and completed suicide. Data are from the National Mortality Followback Survey and refer to 373 suicides, and 518 deaths from motor vehicle accidents as controls. The results of a logistic regression analysis indicated that, for females, the greater the BMI the greater the suicide risk. However, this relationship did not hold up under controls for race and other covariates of BMI. For males, the BMI was not significantly related to suicide risk either at the bivariate or multivariate levels of analysis. The best predictors of suicide were living alone for females, and alcohol abuse for males. 相似文献

My brand new bicycle had been stolen! Disbelief. Anger! Disappointment... I had been riding it for only a day,and was as excited as a,well,a boy with a new bike. Even though I only paid what would be the equivalent of half a tank of gas for my truck back home,I was still sorely put out. 相似文献

This study examined the links between parental divorce, quality of maternal parenting, spousal relationships and middle adolescent
romantic competence in 80 mother-adolescent daughter pairs (40 divorced). Mothers were asked to describe their attitudes and
behaviors with regard to their daughters’ romantic behavior. In addition, mothers were interviewed about their own romantic
experiences when they were at the age of their daughters. Adolescent girls (mean age = 16.98 years; range 16–18) were administered
a comprehensive interview about romantic competence. Findings indicated that adolescent girls from divorced families showed
lower levels of romantic competence, which were expressed in their behavior, attitudes toward relationships and skill in handling
those relationships. Divorce was found to have had an adverse effect on girls’ romantic competence, whereas continued adaptive
parenting and spousal relationships alleviated the effect of divorce. Mothers’ coherent representation of their own adolescent
romantic experiences also alleviated the effect of divorce on daughters’ romantic behavior. Results show the important role
of family relationships in fostering romantic competence among adolescent girls. 相似文献

Previous studies have indicated homophily in depressive symptoms among adolescent friends, resulting from both peer selection
and socialization processes. However, developmental differences and the role of school transitions in these processes have
not been elucidated. A sample of 367 (51% female) adolescents was followed from 6th to 11th grade to investigate prospective
relationships between adolescents’ and their friends’ depressive symptoms in middle school and in high school. Results revealed
that students selected friends with similar levels of depressive symptoms after each school transition. Additionally, friends
appeared to socialize adolescents to become more similar in depressive affect in late middle school years. These findings
suggest normative selection effects after school transitions, followed by socialization effects in middle school, but not
high school. 相似文献

Although adolescents often participate in multiple extracurricular activities, little research has examined how the breadth
of activities in which an adolescent is involved relates to school-related affect and academic performance. Relying on a large,
multi-ethnic sample (N = 864; 55.9% female), the current study investigated linear and non-linear relationships of 11th grade activity participation
in four activity domains (academic/leadership groups, arts activities, clubs, and sports) to adolescents’ sense of belonging
at school, academic engagement, and grade point average, contemporarily and in 12th grade. Results of multiple regression
models revealed curvilinear relationships for sense of belonging at school in 11th and 12th grade, grade point average in
11th grade, and academic engagement in 12th grade. Adolescents who were moderately involved (i.e., in two domains) reported
a greater sense of belonging at school in 11th and 12th grade, a higher grade point average in 11th grade, and greater academic
engagement in 12th grade, relative to those who were more or less involved. Furthermore, adolescents’ sense of belonging at
school in 11th grade mediated the relationship of domain participation in 11th grade to academic engagement in 12th grade.
This study suggests that involvement in a moderate number of activity domains promotes positive school-related affect and
greater academic performance. School policy implications and recommendations are discussed. 相似文献

正第三章五年计划下的经济发展与经济政策①第一节苏维埃经济彻底社会主义化的历程起初,国外并没有把五年计划当回事,仅将其当作一种宣传,意在激励人们工作。这种怀疑论走得太远了;当计划的内容在苏维埃俄国大多得以落实时,怀疑让位于震惊,在某些圈子里,及至痴迷。然而,彻底的怀疑与过度的痴迷一样,都是非理性的。但是,怀疑论者有一点是对的:一眼就能看出,计划的巨额投资并没有带来一般生活水准的同步改善。同时,不要忘记,掌控所有资源、以 相似文献
