Relationships Between Social Support,Internal Assets,and Life Satisfaction in Korean Adolescents

In previous literature, social support has been reported to have a significant, positive relationship with life satisfaction. However, few studies have examined this relationship among Korean youths and how their psychological functioning is associated with both social support and life satisfaction. This study investigated the associations between different sources of social support (i.e., family, peer, and teacher), psychological factors (i.e., self-efficacy and emotional regulation), and life satisfaction, in a sample of 1133 Korean adolescents. The possibility of sex differences in these relationships was also investigated. Results indicated that only family support had a direct relationship with life satisfaction for male adolescents; however, all three types of social support were found to have a significant, indirect relationship with life satisfaction for male adolescents through both psychological factors. In contrast, all three types of social support had a direct relationship with life satisfaction of female adolescents. Additionally, self-efficacy had a mediating effect on the relationship between the social support from family and teachers and life satisfaction of female adolescents. The results and implications of the study are discussed.     

建构反应题中能力估计准确性的影响因素:评分者人数和项目个数的交互作用

采用康春花、孙小坚和曾平飞(2016)提出的等级反应多水平侧面模型探讨了评分者人数和项目个数对被试能力估计准确性的影响。模拟研究的结果表明:(1)随着项目个数的增加,估计值与真值之间的相关也不断增加;(2)评分者人数和项目个数在平均绝对偏差(MAB)和误差均方根(RMSE)上的主效应均显著,两者间的交互效应也显著;(3)简单效应分析发现,当项目较少时,3个评分者条件下的能力估计准确性最好; 随着项目个数的增加,4个评分者的估计误差迅速下降,且表现变为最好。     

3～6岁儿童人格发展的群组序列追踪研究

目的:运用自编幼儿人格发展教师评定问卷对幼儿人格进行追踪测量,探讨其年龄及性别发展特点。方法:用整群抽样法选取3~3.5岁、3.5~4岁、4~4.5岁3个年龄群组幼儿为被试,采用群组序列的追踪设计,进行为期1年半的追踪测量,结合潜变量增长曲线模型和多层线性模型处理数据,探讨幼儿在3~6岁间人格的发展特点。结果:(1)幼儿的智能特征、认真自控、外倾性、亲社会性、情绪稳定性5个人格维度在3~4岁发展最快,4~5岁持续增长但发展速度放缓,到5~6岁时趋于平稳;(2)女孩的认真自控和亲社会性在3岁时显著高于男孩,但在3~6岁间的增长率不存在差异,即女孩的认真自控和亲社会性在幼儿阶段发展水平始终高于男孩。结论:从家庭进入幼儿园的环境变迁促使了幼儿人格的进一步发展,5岁左右幼儿人格开始初步形成;女孩的认真自控和亲社会性水平在幼儿阶段始终高于男孩。     

Helping Peers Seek Professional Treatment for Depression Among Young South Koreans: An Application of the Theory of Planned Behavior

This study examined the applicability of the theory of planned behavior to understand factors that influence whether young South Koreans help peers with depression to seek professional counseling services. The structural equation modeling on the survey data collected from 191 South Korean students suggests that subjective norms and behavioral control could be salient factors for young South Koreans to take initiative and assist their peers in need of counseling services. Este estudio examinó la aplicabilidad de la teoría del comportamiento planificado para comprender factores que influyen sobre la decisión de jóvenes surcoreanos de ayudar a sus compañeros que sufren de depresión a buscar ayuda profesional a través de servicios de consejería. El modelo de ecuación estructural de los datos de la encuesta recogidos de 191 estudiantes surcoreanos sugiere que las normas subjetivas y el control del comportamiento podrían ser factores destacados para los jóvenes surcoreanos a la hora de tomar la iniciativa y ayudar a sus compañeros que necesitan servicios de consejería.     

HIV prevention with persons with mental health problems

The HIV seroprevalence rate among persons with mental health problems (PMHP) is substantially higher than that of the general population in the United States. This study examines the efficacy over 12 months of an HIV prevention program with 99 individuals attending outpatient mental health clinics who were randomly assigned to receive either: (a) a seven-session, small-group intervention of Project LIGHT (Living in Good Health Together); or (b) a one-session video intervention. Regression analyses of data from 87% of the sample interviewed at 1-year follow-up revealed that intervention group membership was associated with significantly fewer sexual risk acts. A significant intervention effect for condom use was found for 72% of the sample who were African American, but not for Latino or Caucasian participants. Results from this study suggest that HIV risk reduction groups such as Project LIGHT may have utility in public mental health care settings.

Determination of atomic structure of phason planes in the ξ′-Al–Pd–Mn phase

The atomic structures of specific types of linear defects (phason lines) and planar defects (phason planes) in the complex metallic alloy phase ξ′-Al–Pd–Mn have been determined by high-resolution electron microscopy (HREM) and theoretical HREM simulation. The results show that a representational atomic structural model for phason planes can be constructed by introducing a shift between two parts of the perfect crystalline structure using a translation vector of r ?=?(1/2) a ?+?(1/2τ) c . This typical phason plane is normally parallel to the (001) plane of the ξ′-Al–Pd–Mn phase and consists of phason lines, which are arranged side-by-side with their linear direction parallel to the [010] axis. HREM simulations, based on the structural model for both edge-on and inclined types of phason lines, agree well with the experimental results. Taking into account the fact that the structural difference between various curved phason planes arises from the variation in the arrangement of individual phason lines, the atomic structures of the edge-on and inclined phason lines can be used to explain the various curved phason planes frequently observed in the ξ′-Al–Pd–Mn phase.     

Four-phonon model of soft-matter quasicrystals for studying thermodynamics

Four-phonon model of soft-matter quasicrystals is proposed, in which there are three solid phonons and one fluid phonon. With this model, the vibration spectrum of soft-matter quasicrystals can be obtained. The generalized Debye frequency, generalized Debye temperature and the thermodynamic functions of soft-matter quasicrystals are observed. The results on the specific heat of soft-matter quasicrystals demonstrate the contributions of both solid phonons and fluid phonon, respectively.
