An Exploration of Toddlers' Problems in a Search Task

Toddlers show a surprising lack of knowledge about solidity when they are asked to search for a ball that rolled behind a screen and stopped at a barrier whose top was visible above the screen. They search incorrectly, failing to take into account the position of the barrier. This study examined details of this failure by simplifying the task in 2 ways: by using a search task that did not require children to understand solidity, and by using a prediction task that did not require children to conduct a search. For the prediction task, children had to predict where a ball was going to stop when a barrier intersected its trajectory. Children 2.0 and 2.5 years old were able to conduct a simple search and could predict, to some extent, where the ball was going to stop when the barrier was fully visible. Children did not show this predictive knowledge when the barrier was partially occluded by the screen.

多维视野中的中国古代文论研究

本文试图以“天人合一”为例证 ,旨在阐述对中国古代文论的研究必须作一种全方位的审察。既可以采用文化之维 ,以见出其精神意蕴 ,也可以运用逻辑演绎 ,以寻绎其基本模式 ;既可以采用我注六经 ,以见出历史本真 ,又可以使用六经注我 ,以领悟其现代的启示。通过这种多种角度的整合与建构 ,我们可以透视中国古代文论的整体风貌。这样对于当前呼声日隆的“中国古代文论的现代转型” ,无疑具有一种参照价值     

Personal Characteristics, Unemployment, and Anxiety among Highly Educated Immigrants

This exploratory study examines the relationship between personal resources (sense of potency, marital quality, social support from family and friends), the duration of unemployment, and the level of state anxiety experienced by highly educated, unemployed, middle‐aged immigrants. Studying the anxiety levels among populations at‐risk such as unemployed immigrants is particularly important in the context of situations of military conflict. In such situations, when formal support systems are in the process of erosion, the unemployed must increasingly rely on social and familial support. The following measures were examined in an anonymous, self‐report questionnaire: potency (defined as a person's enduring confidence in his/her own capacities and confidence in, and commitment to, his/her social environment which is perceived as being characterized by a basically meaningful order and just distribution of rewards), social support from friends and family, marital quality, and state anxiety. Results indicate that personal resources – particularly potency and social support from family – predicted the level of state anxiety among immigrants. Duration of unemployment was also positively correlated with state anxiety. A major recommendation that emerges is the need to foster the development of social support groups consisting of both veterans and new immigrants in order to broaden the social ties of the immigrants. This may assist newcomers not only in finding jobs, but also in coping with political and economic uncertainties in a new cultural context.
