Factors Contributing to Gender Differences in Depressive Symptoms: A Test of Three Developmental Models

In a longitudinal study on 115 early adolescents, the impact of major events, relationship stressors, and coping style in interaction with biological changes on depressive outcome in late adolescence were explored. Three developmental models proposed by Nolen-Hoeksema and Girgus (1994, Psychol. Bull. 115: 424–433), which attempt to explain the emergence of gender differences in adolescent depressive symptoms, were tested. Multiple regression analyses conducted to test Model 1 identified two etiological factors associated with gender differences of depression, namely, stress in the adolescent–mother relationship and a more negative body image. Tests of Model 2 revealed etiological factors which correlated with depression in adolescent girls but not adolescent boys. The correlational patterns of avoidant coping and body image emerged as relevant factors for Model 2. Finally, tests of Model 3 searched for factors which were more likely to be observed in adolescent girls than boys and which would put girls at risk should they interact with a third etiological factor. Early maturational timing emerged as a factor for Model 3.     

The Same Old Song?—Stability and Change in Relationship Schemas from Adolescence to Young Adulthood

Relationship schemas are core elements of personality that guide interpersonal functioning. The aim of this study is to examine stability and change in relationship schemas across two developmental epochs—adolescence and young adulthood—in the stories that people tell about their interactions with others. Using the Core Conflictual Relationship Theme Method, relationship themes were coded from semistructured interviews conducted in adolescence and again at age 25. The sample consisted of 40 participants in a longitudinal study of adolescent and young adult psychological development. There was considerable stability in the frequency with which particular themes were expressed in the narratives of adolescents and young adults. Significant changes from adolescence to young adulthood included a decrease in the perception of others as rejecting and of the self as opposing others. Young adults saw themselves and others more positively, and used a broader repertoire of themes in their relationship narratives than they had as adolescents. The basic continuity and particular changes in relationship schemas found in this study are consistent with knowledge about the adolescent-to-young-adult transition derived from other empirical and clinical findings. Relationship schemas may be rich units of study for learning about the development of interpersonal functioning.     

The Structure and Stability of Externalizing and Internalizing Problem Behavior During Early Adolescence

The first aim of this study was to examine the structure of externalizing and internalizing problem behavior during early adolescence. Our second aim was to determine the stability of these problems for boys and for girls over time. A total of 650, 13–14-year-olds filled out (an expanded version of) the Youth Self-Report [YSR; Manual for the Youth Self-Report and 1991 Profile. Department of Psychiatry, University of Vermont, Burlington] 2 times with a 1-year interval. By using confirmatory factor analyses (CFA) to test a series of competing models, a hierarchical model provided the best representation of the structure of problem behavior at both Time 1 and Time 2: externalizing and internalizing problem behavior represent distinct aspects but the model also demonstrates the existence of comorbidity at a higher level. This model appeared to be stable over time for both boys and girls. The relative stability of problem behavior was found to be high for boys and girls. Absolute stability for both externalizing and internalizing problems appeared to be higher for boys scoring in the lower range of problem behavior.

刑法因果关系研究

因果关系是指行为与结果之间决定与被决定、引起与被引起之间的关系。在刑法中,将某一结果归咎于某人的时候,往往需要查明其行为与结果之间是否存在刑法上的因果关系。因此,因果关系在定罪中具有重要意义。但并不意味着可以过分夸大因果关系在犯罪构成中的地位。此外,要正确认识刑法中的因果关系,应从事实上的因果关系与法律上的因果关系两方面进行考察,而不应纠缠在必然性与偶然性这样一些哲学问题上。

Assessing Stability and Change in Criminal Offending: A Comparison of Random Effects, Semiparametric, and Fixed Effects Modeling Strategies

An important theoretical problem for criminologists is an explanation forthe robust positive correlation between prior and future criminaloffending. Nagin and Paternoster (1991) have suggested that the correlationcould be due to time-stable population differences in the underlyingproneness to commit crimes (population heterogeneity) and/or thecriminogenic effect that crime has on social bonds, conventionalattachments, and the like (state dependence). Because of data andmeasurement limitations, the disentangling of population heterogeneityand state dependence requires that researchers control for unmeasuredpersistent heterogeneity. Frequently, random effects probit models havebeen employed, which, while user-friendly, make a strong parametricassumption that the unobserved heterogeneity in the population follows anormal distribution. Although semiparametric alternatives to the randomeffects probit model have recently appeared in the literature to avoid thisproblem, in this paper we return to reconsider the fully parametric model. Viasimulation evidence, we first show that the random effects probit modelproduces biased estimates as the departure of heterogeneity from normalitybecomes more substantial. Using the 1958 Philadelphia cohort data, we thencompare the results from a random effects probit model with a semiparametricprobit model and a fixed effects logit model that makes no assumptions aboutthe distribution of unobserved heterogeneity. We found that with this dataset all three models converged on the same substantive result—evenafter controlling for unobserved persistent heterogeneity, with models thattreat the unobserved heterogeneity very differently, prior conduct had apronounced effect on subsequent offending. These results are inconsistentwith a model that attributes all of the positive correlation between priorand future offending to differences in criminal propensity. Sinceresearchers will often be completely blind with respect to the tenabilityof the normality assumption, we conclude that different estimationstrategies should be brought to bear on the data.     

褥垫层厚度对带帽刚性桩性状的研究

对三个不同地点的带帽刚性桩复合地基工程进行试验监测,根据试验监测数据结果进行分析,可见褥垫层不同厚度对带帽刚性桩承载力和沉降变形的影响：设计褥垫层在某一合适的厚度,能有效降低桩身承载力,提高桩间土的承载力,使桩和桩间土合理共同承担荷载,降低复合地基沉降变形,减少地基对基础的应力集中,对工程实际有一定的指导意义.在试验分析的基础上,理论研究刚性桩带帽的条件,在褥垫层合适厚度下,单桩承载力、桩间土承载力、桩间土折减系数对刚性桩带帽都有影响,当条件符合时设置刚性桩带帽可以提高复合地基承载力,降低沉降变形.     

二层次四要件犯罪构成论——兼议正当化行为的体系地位

以解决正当化行为在犯罪论体系中地位不定,及其与犯罪构成关系不明为突破口;以反映定罪过程、权力与权利的平衡以及对抗制的诉讼程序特点为价值立场;兼顾中国已有的理论与实务情况,主张在我国犯罪构成论的应有结构为两层次四要件犯罪构成结构.此即:第一层次,三个要件,依次为犯罪客观要件、犯罪主体要件和犯罪主观要件;第二层次为犯罪客体一个要件,其中,正当化行为等作为排除犯罪客体的事由在此纳入犯罪构成要件之中.无此事由,犯罪即告成立.
