书写自己的生命华章

假如有人给你一支笔,一支密封的、纯色的水笔,里面有多少墨水你无法看到,很可能刚刚试着写几个字就能用干,也可能足够写一部或几部皇皇巨著,流传千古,使世事为之而改变。而这一切你在动笔之前无法知晓。     

坐轮椅的人能走多远

1979年1月19日,一位19岁的青年与一位朋友在加拿大的范库弗峰滑雪。他突发奇想,想尝试一种他从未玩过的特技——从朋友两腿中间滑过去。结果他以极快的速度撞到了朋友身上。他似乎听到了自己骨头断裂的声音。"我摔断了脖子。"他对朋友说。     

Numerical Calculation of Concrete Slab Response to Blast Loading

In the present paper, a dynamic plastic damage model for concrete has been employed to estimate responses of a reinforced concrete slab subjected to blast loading. The interaction between the blast wave and the concrete slab is considered in 3D simulation. In the first stage, the initial detonation and blast wave propagation is modelled in 2D simulation before the blast wave reaches the concrete slab, then the results obtained from 2D calculation are remapped to a 3D model. The calculated blast load is compared with that obtained from TM5-1300. Numerical results of the concrete slab response are compared with the explosive test carried out-in the Weapons System Division, Defence Science and Technology Organisation, Department of Defence, Australia.

Prenatal depression, violence, substance use, and perception of support in pregnant middle-class women

The purpose of this study was to explore the vulnerability for postpartum depression among financially, educationally, and socially advantaged middle-class women (n = 31). Twenty-nine percent reported prenatal depression, 13% reported intimate partner violence, and 22% reported concerns with partner relationships and support expectations after delivery. No illegal substances were reported; however, a past history of smoking and excessive use of caffeine was disclosed. Implications for practice focus on the need to screen and implement intervention programs for these social problems and to adopt measures as a universal standard of care for all women, regardless of demographic advantages.

Gender effects in children's beliefs about school performance: a cross-cultural study

Do young boys and girls understand what leads to academic success (e.g., talent, effort, good teaching, luck) in the same way? Do young girls and boys have equivalent perceptions of their academic competence? Are these beliefs engendered in the same way across sociocultural contexts? In a cross-cultural study of over 3,000 children in grades 2 to 6, ages 7.2 to 13.6, we discovered that boys and girls around the world have very similar ideas about what generally leads to academic success. Moreover, in the few contexts where boys' and girls' academic performances were equal, their beliefs were also equal. However, when girls outperformed boys, their beliefs in their own talent were no greater than boys' beliefs, even though they did have stronger beliefs than boys in other facets of their achievement potential (e.g., putting forth effort, being lucky, getting their teacher's help). Our findings support the generally close correspondence between children's achievement and their competence-related beliefs, with the exception that young girls appear to specifically discount their talent. The effects held regardless of the children's achievement, intelligence, or age (approximately 8 to 13 years). Girls were more biased in some contexts than in others, however, suggesting that competence-related biases are rooted in culture-specific aspects of school settings.     

兩种会晤

请你試想一下,在你面前有这样兩个学生:维嘉[一]和瓦尼亚。他們兩个絕少相像之处。维嘉的学習成績是4分或5分,總是很整潔的,对教師很尊敬,走進教員室時一定先敲門,一進來就向老師问好,离開時也从没忘記过很有礼貌的說“再会”。甚至在课間休息時,也明顯的看出維嘉是遵守紀律的榜样——靜靜的站在一旁,或者安靜的在走廊里走,不参加爭論,只是微笑,不像別的孩子那样嚷着玩、但瓦尼亞就完全不     

Acculturation, substance use, and deviant behavior: examining separation and family conflict as mediators

This longitudinal study examined how separation and family conflict mediated the effects of two acculturation variables (English language use and generational status) on substance use (alcohol, tobacco, and marijuana use) and deviant behavior outcomes in a Mexican American high school age sample. Structural equation modeling indicated that separation was a significant mediator of the relationship between acculturation and alcohol use, tobacco use, and deviant behavior. Family conflict mediated the effects of acculturation on marijuana use and deviant behavior. Model comparisons across gender groups suggested that generational status was an influential acculturation measure for females but not males. Additionally, English language use maintained a direct effect on marijuana use among females, whereas this relationship was mediated by separation for males.
