Peer relations across contexts: individual-network homophily and network inclusion in and after school

Peer relations across 2 contexts (in school and after school) were examined for 577 participants, approximately 12 years old, from 3 middle schools in Milan, Italy. The primary research questions were: Do peer networks from different contexts uniquely contribute to explaining variance in individual behavior? Do measures of peer preference and peer network inclusion across contexts uniquely contribute to explaining individual depressive symptoms? Structural equation models showed that both the in-school and the after-school peer networks uniquely contributed to explaining variance in 2 types of individual problem behavior (in-school problem behavior, after-school delinquency), and that similarity with the 2 peer networks varied according to behaviors specific to each context and across gender. Finally, both in-school and after-school peer network inclusion contributed to explaining variance in depressive symptoms, after controlling for classroom peer preference.

Teenage pregnancy: a small comparison group of known mothers

To obtain confirmation of the findings of the authors' earlier comparison of ever-pregnant and nonpregnant Black high school students from Tennessee, 16 students confirmed to be pregnant were substituted for the 33 subjects in the original study whose pregnancy status was based solely on self-report. The nonpregnant control group of 251 teens was utilized in both analyses. Although the confirmed pregnant group was too small to repeat the regression analysis, striking concordance of findings between the 2 studies emerged for all dependent variables except the Eysenck Personality Questionnaire anxiety scale. The lower anxiety scores recorded among subjects in the original study may be either a statistical artifact or a reflection of the fact that these pregnant teens remained in school while subjects in the second study were enrolled in programs centered around their pregnant status. Sexual activity scores were strong or moderate significantly more often in both groups of pregnant teens compared to their nonpregnant counterparts. Interesting was the finding that 81% of pregnant teens regarded romance novels and soap operas to be accurate portrayals of real-life dating relationships compared to only 49% of nonpregnant teens. On the other hand, only 56% of the pregnant subjects regarded their own relationships to have this romantic quality. In a future study, the role of such uncritical romantic ideals in adolescent pregnancy risk will be investigated in a larger sample.     

我为何而生

人为何而生?每一个人,既生于世,必有他独特的用处。这是一位老太太教我的。她晚年因战祸而家破人亡,卖掉了大房子,只留下偏处旧地产一隅的小茶室自住。这件事发生时,老太太正带着老家人,在伊豆山温泉旅行。有个17岁男孩在伊豆山投海自杀,被警察救起。他是个美国黑人与日本人的混血儿,愤世嫉俗,末路穷途。老太太到警察局要求和青年见面。警察知道老太太的来历,同意她和青年谈谈。“孩子。”她说时,青年扭过头去,像块石头,全不睬她,老太太用安详而柔和的语调说下去,“孩子,你可知道,你生来是要为这个世界做些除了你没人办到的事吗?”她反复说…
