小学生课堂问题行为与心理素质的关系:一项观察研究

为科学、客观的了解小学生课堂问题行为的现状并探讨与心理素质的关系,采用Martin等人提出的TPOT观察范式对重庆市潼南区某小学4-6年级117名学生的课堂问题行为进行录像、编码,并施测小学生心理素质问卷简化版。结果表明:(1)T-POT观察范式在本研究中具有适用性;(2)任务偏移是小学生最常见的课堂问题行为;(3)小学生课堂问题行为的表现存在显著的性别、年级差异;(4)在控制了年级、性别、班级环境变量后,心理素质能够显著负向预测课堂问题行为。     

The Predictors of Suicidality in Previous Suicide Attempters following Case Management Services

Suicide attempts constitute a serious clinical problem. People who have attempted suicide are at an elevated risk for additional suicide attempts, but there is limited evidence regarding the predictors of suicidality of suicide attempters following case management services. In the present study the indicators of suicidality after case management were examined. A total of 1,056 subjects who had recently attempted suicide were recruited from January 1, 2011, to June 30, 2011. The suicide prevention center of Kaohsiung City in Taiwan provided case management services and followed up on suicide attempt cases for 6 months. The salient factors for repeat suicide attempts were estimated using a logistic regression analysis. The results showed that multiple factors, including a “willingness to receive mental health services during a crisis,” “social support,” “a history of mental disorders,” and “a history of suicide,” could predict repeat suicide attempts with hazard ratios (0.58, 0.54, 3.84, 1.51) and 95% confidence interval (0.39–0.86, 0.36–0.83, 2.41–6.10, 1.03–2.21). The four factors mentioned above were the most accurate predictors of subsequent suicidality when case management services were utilized after 6 months of follow‐up. The findings of our study could help clarify future strategies for suicide prevention.     

Price-directive decision making in hierarchical systems with conflicting preferences

In this paper we consider a classical model of price-directive decision making in hierarchical organizations, namely Dantzig-Wolfe decomposition, well known from single-objective programming. Here, however, we allow for preference differences that are usually observed between a central unit and a subunit in an organizational structure. The procedure models, therefore, how decision making may evolve in a context with decentralized information as well as intra- and interpersonal conflicts. Several numerical experiments with the procedure have been performed. The results of those experiments demonstrate that the procedure in many instances converges towards an efficient solution, despite the differences in the criteria weights used in the master problem and the subproblem respectively. This suggests that some amount of goal discordance need not prohibit efficient decision making in a hierarchical organization.

Starting small: Revisiting young children's perceptions of social withdrawal in China

In this reply to the commentaries by Xinyin Chen, Charissa Cheah, Yiyuan Xu, and Dawn Watling, we further discuss the conceptual and methodological challenges that arise when attempting to study beliefs about social withdrawal (1) in the unique cultural context of China and (2) in the unique developmental age period of early childhood.
