The Heterogeneity of Truancy among Urban Middle School Students: A Latent Class Growth Analysis

This longitudinal study explores heterogeneity of middle school students by identifying subgroups of youth characterized by distinct truancy trajectories and by determining disability profiles that distinguish these subgroups. Participants comprised an entire 7th through 9th grade student population, with approximately 58,000 students, in a large urban school district. Latent class growth analysis was used to identify subgroups of truant youth. This analysis yielded five distinct truant subgroups: Very-Low (37 %), Low (43.4 %), Declining (3.3 %), Rising (12.8 %), and Chronic (3.6 %). Further, differential disability profiles were found in each subgroup with the control of demographic characteristics (i.e., gender, race/ethnicity, free/reduced lunch, Limited English Proficiency, grade, and prior school absences), students with serious emotional disturbance and learning disabilities demonstrated amplified risks of being classified in the Chronic or Rising subgroups, which show chronic or incremental upward truant trajectories over time. These findings are discussed in terms of their implications for future research.     

幼儿从电视中学单词──项伴随学习的研究

对幼儿从电视中伴随学习单词的可能性及其影响因素进行了初步的探讨。４０名小班幼儿和４６名大班幼儿参加了实验,他们在接近自然的状态下观看有字幕的动画片。结果发现：幼儿在无任何指导的情况下观看有字幕的动画片,能伴随学习到汉字,这表明,电视对幼儿的词汇发展有着积极的影响;不同性别的儿童都能同等程度地从电视中伴随学习到单词;词义的伴随学习受幼儿原有的词汇水平和幼儿对目标词熟悉程度的影响;词音的伴随学习只发生在词汇水平较高的幼儿当中,并且随着幼儿对目标词熟悉程度的增加而增加;词音和词义的伴随学习存在频度效应。     

Assessing the Burdens of Leadership: Effects of Formal Leadership Roles on Individual Performance Over Time

This study adopted a role-based perspective in examining whether changes in performance over time (i.e., dynamic criteria) were a function of changes in individual leadership role responsibilities. Longitudinal data from captains in the modern era of the National Hockey League ( N = 201) were used to test a dynamic criterion hypothesis using multilevel growth modeling. Time ( k = 10) was modeled as a random effect, whereas captain status (i.e., leadership role responsibility) was included as a time-varying covariate. Individual performance was measured as the adjusted points (goals scored plus assists adjusted for individual and historical effects). Results of a series of model building steps that included the examination of alternative complex error structures indicated an overall negative performance trend. Those seasons in which a player assumed formal leadership responsibilities (i.e., team captain) were associated with better performance compared to seasons in which the player had no leadership responsibilities. These results were found to be robust even after controlling for individual performance in the previous season. Results are discussed in terms of the possible positive implications for individual performance and the motivation to lead through developing a culture in which leadership positions are highly valued by the organization, visible to others on the team, and where leadership responsibilities do not interfere with task performance.     

贝施特和智顗论"恶"的宗教价值--兼谈宗教中的"善恶"观念

谈"善"论"恶"是宗教中的永恒话题,但宗教中的"善恶"并非仅仅是伦理学意义上的善恶,而是包括宗教修持意义上的"善恶".一般而言,"善"是有助于宗教修持的,但是贝施特和智顗却分别站在犹太教和中国佛教天台宗的立场揭示了"恶"对于宗教修持的积极作用,阐明了"恶"的宗教价值,尽管他们所说的"恶"的内涵不同.其中贝施特主张"恶"中分有"善"的神性,通过"恶"可以回归上帝;智顗主张"恶"中本具"善"的"实相",通过观"恶"的"烦恼心"可以达到解脱.可以说,在"恶"的宗教价值这个问题上,贝施特和智顗进行了一次跨宗教的对话.     

国内元认知的相关研究及其展望

元认知这一概念是由美国发展心理学家弗莱维尔(Flavell)在1976年正式提出来的。至今,学者们对其进行了广泛深入的研究,无论是在理论还是实证方面都取得了丰硕的成果。文章首先对元认知(metacognition)的概念作了阐述,接着陈述了当前关于元认知的结构比较认可的两分法以及三分法,并提出了关于元认知结构的看法。然后对目前国内元认知的相关研究做一综述,最后文章在分析过去研究所存在问题的基础上提出了对元认知研究的展望。     

恻隐之心:“同感”、“同情”与“在世基调”

一、问题的提出恻隐之心,人皆有之(《孟子·告子上》);无恻隐之心,非人也(《孟子·公孙丑上》):最能体现儒家对人性理解的一个关键词,莫过于恻隐之心。因此,把握恻隐之心的深刻内涵,对我们理解儒家的人性论至关重要。究竟何为恻隐之心?它与孟子提到的其他三种心(羞恶之心、辞让之心恭敬之心、是非之心[参见同上])关系如何?近年来,西方学者往往从同     

Orthographic neighborhood size effect in Chinese character naming: orthographic and phonological activations

The present study examined the effects of orthographic neighborhood (N) size on the cognitive processes underlying Chinese character reading. Previous research has shown increasing N size facilitates word naming and recognition performance in alphabetic languages. Experiment 1 revealed that a large N size was associated with a general inhibition of processes underlying character reading, in contrast to previous findings with alphabetic languages. This inhibitory effect was influenced by regularity and consistency. Experiment 2 sought to assess the effects of higher-frequency neighbors on character naming performance. The results revealed that higher-frequency neighbors with different pronunciation to the target interfered with the phonological retrieval of targets. We propose that this type of interference may have caused the N size effect observed in Experiment 1. The results of Experiment 3 revealed that a large N size facilitated target naming in the absence of higher-frequency neighbors. The current results shed light on the processes underlying character naming, and we propose possible cognitive mechanisms of the N size effect on Chinese character naming.     

论我国养老金的替代率

养老金替代率看似一个具体的、"技术性的"问题,实际上却影响养老保险制度运行的全局.国家政策对养老金替代率的影响是全局性的、决定性的.从现在开始,我国养老保险建设将进入以合理调节养老金替代率为重点,完善制度运行的阶段.未来几十年间养老金替代率的调节将仍然主要依靠国家政策和资金的投入.我国能够解决未来调节养老金替代率所需的资金问题.未来调节养老金替代率应遵循保障基本生活、共享发展成果、实现社会公平的原则.     

Role ambiguity, employee gender, and workplace friendship

The importance of workplace friendship is recognized by researchers and practitioners, but its antecedents with respect to work roles are not well understood. Employees' gender might moderate a relationship between work roles and friendships. Data from a survey of 221 international tourist hotel employees showed that a key aspect of job support, role ambiguity, was negatively related to having workplace friendships. However, employees' gender did not moderate this relationship. Role clarity (the opposite of role ambiguity) may facilitate workplace friendships.     

简论跨国公司经营中的企业社会责任

基于利益相关者理论的企业社会责任实践能够有效地建立与维持企业的长期竞争优势。将企业社会责任理念融入企业的经营战略和经营方式、作为企业文化的核心内容,是跨国公司经营获得成功的重要因素。随着我国越来越多的企业走出国门开展跨国经营,我国跨国经营企业应努力协调中国传统文化价值观与西方文化价值观之间的矛盾和冲突,以尊重之心处理好企业与利益相关者的关系,逐步提升企业社会责任意识,为所在国的经济社会发展做出贡献。
