Psychometric Evaluation of the Affect Regulation Checklist: Clinical and Community Samples,Parent-Reports and Youth Self-Reports

The Affect Regulation Checklist (ARC) was designed to capture affect dysregulation, suppression, and reflection. Importantly, affect dysregulation has been established as a transdiagnostic mechanism underpinning many forms of psychopathology. We tested the ARC psychometric properties across clinical and community samples and through both parent-report and youth self-report information. Clinical sample: Participants included parents (n = 814; M_age = 43.86) and their child (n = 608; M_age = 13.98). Community sample: Participants included independent samples of parents (n = 578; M_age = 45.12) and youth (n = 809; M_age = 15.67). Exploratory structural equation modeling supported a three-factor structure across samples and informants. Dysregulation was positively associated with all forms of psychopathology. In general, suppression was positively associated with many forms of psychopathology, and reflection was negatively associated with externalizing problems and positively associated with internalizing problems.     

国际经济失衡的成因:新形态国际分工的视角

从国际经济失衡的特征出发,本文提出了从"服务-制造"新形态国际分工的视角理解国际经济失衡的成因,并分析了其引致失衡的机制.新形态国际分工下服务贸易和货物贸易开放的非对称性是导致失衡最为直观的原因;国际分工演进中不断恶化的收入分配导致了"服务"国经济的虚拟化、过度需求和贸易逆差,"制造"国的内需不足、生产相对过剩和贸易顺差;国际货币体系的内在缺陷则是新形态国际分工下美国利用金融"跨时比较优势",满足其过度消费需求的制度基础.     

论人际交往诚信及其意义

人际交往诚信关注的是作为公民的个体在社会公共生活领域、家庭生活领域中人际互动的诚信关系,情感性、非功利性和基础性是其特点。人际交往诚信是个人基本的道德品质,是建立社会诚信的基础。它有利于建立和谐的人际关系,能满足个人安全需要,减少不必要的代价。     

Establishing Positive Youth Development Approaches in Group Home Settings: Training Implementation and Evaluation

This article reports on a training program for group home supervisors that was designed to utilize positive youth development principles in work with youth transitioning from care to independent living. Over a period of 5 months, eight one-day training sessions took place across one state in the U.S. (Massachusetts) with a total of 186 group care staff in attendance. The evaluation consisted of three components: observation of participant feedback during training, training day post-test, and follow-up with participants 2–3 months after training. Implications of the data, particularly barriers to implementation of training programs, are discussed.     

Comparing the Level of Positive Tendency in a Life Satisfaction Evaluation between Chinese and Western People

We demonstrate that people from Chinese cultural backgrounds have a smaller positive tendency in life evaluation compared to people in typical Western cultures. Participants first described their imagined best and worst life and then rated their current life on scale anchored by those imaginings (Mellor et al. International Journal of Social Research Methodology Theory and Practice, 2, 263–278, 1999), with scores above 50 indicating the strength of positive tendency. We compare responses from 82 Taiwanese students to data from the 22 Australian students in Mellor et al.’s (International Journal of Social Research Methodology Theory and Practice, 2, 263–278, 1999) study. Results of independent t tests support the hypothesis that culturally Chinese subjects have a lower positive tendency (65.32%SM) than Australian participants (76.12%SM) in life satisfaction evaluation. Shih-jung Lee and Chia-huei Wu have made equal contributions to this study.

THE NEUROBIOLOGY OF AFFECTIVE INTERVENTIONS: A CROSS-THEORETICAL MODEL

The integration of information from neuroscience with the practice of psychotherapy presents with numerous challenges. However, neuroscience research can guide practitioners in the purposeful use of the therapeutic relationship to enhance clinical outcomes. This article reviews such research pertinent to mental health and psychotherapy, and presents an a-theoretical model of intervention, guided by this information that can be incorporated into various therapeutic orientations.     

Strong control, conservative point estimation and simultaneous conservative consistency of false discovery rates: a unified approach

Summary.  The false discovery rate (FDR) is a multiple hypothesis testing quantity that describes the expected proportion of false positive results among all rejected null hypotheses. Benjamini and Hochberg introduced this quantity and proved that a particular step-up p -value method controls the FDR. Storey introduced a point estimate of the FDR for fixed significance regions. The former approach conservatively controls the FDR at a fixed predetermined level, and the latter provides a conservatively biased estimate of the FDR for a fixed predetermined significance region. In this work, we show in both finite sample and asymptotic settings that the goals of the two approaches are essentially equivalent. In particular, the FDR point estimates can be used to define valid FDR controlling procedures. In the asymptotic setting, we also show that the point estimates can be used to estimate the FDR conservatively over all significance regions simultaneously, which is equivalent to controlling the FDR at all levels simultaneously. The main tool that we use is to translate existing FDR methods into procedures involving empirical processes. This simplifies finite sample proofs, provides a framework for asymptotic results and proves that these procedures are valid even under certain forms of dependence.
