Factors Influencing Positive Interactions Across Race for African American, Asian American, Latino, and White College Students

This study explores the various factors that promote positive interactions across race for African American, Asian American, Latino, and White college students. A longitudinal survey was administered to all incoming students at nine public institutions (with a follow-up survey given at the end of their second year), examining activities related to cross-racial interaction and outcomes. This knowledge will be useful for college administrators, institutional researchers, and faculty as they work to meet the challenge of preparing students for a pluralistic society. The results of this study begin to delineate the conditions under which positive intergroup relations can be fostered in college and the key factors that inhibit or restrain the benefits such interactions bring to the development of students for a diverse workplace and pluralistic democracy.     

Relative roles of general and complementation language in theory-of-mind development: evidence from Cantonese and English

Complex complements are clausal objects containing tensed verbs (e.g., that she cried) or infinitives (e.g., to cry), following main verbs of communication or mental activities (e.g., say, want). This research examined whether English- and Cantonese-speaking 4-year-olds' complement understanding uniquely predicts their representation of other minds (i.e., theory of mind). Results showed that neither meaning of main verbs (communication vs. desire) nor complement structure (tensed vs. infinitival) affected the correlation between complement understanding and theory of mind. More important, the correlation became insignificant after controlling for general language comprehension. These findings led to the conclusion that the syntax of complement per se does not contribute uniquely to theory-of-mind development; general language comprehension is a more important factor to consider.

The effects of classroom-based dynamic seating interventions on academic outcomes in youth: a systematic review

The purpose of this systematic review was to synthesise and evaluate the literature on the effects of classroom-based dynamic seating interventions on academic-related outcomes, among school-aged children and adolescents. A secondary aim was to examine the effects of interventions on students’ sedentary behaviour and physical activity levels. In September 2017, four electronic databases (PsycINFO, PubMed, SPORTDiscus, Web of Science) were searched and a total of 5138 titles and abstracts were reviewed. Studies that examined associations between a classroom-based dynamic seating intervention and at least one academic-related outcome in school-aged children or adolescents were included. A best-evidence synthesis and narrative approach was implemented to synthesise the evidence. Thirteen studies published between 2003 and 2017 were identified that met the inclusion criteria for the review. There is some evidence that classroom-based dynamic seating interventions could have positive effects on the in-seat behaviour, academic engagement and attention of school aged-children and adolescents, predominantly those with attention difficulties. It is currently unclear whether dynamic seating has positive effects on students’ on-task behaviour, disruptive behaviour, memory, concentration or academic achievement. No intervention was found to have a detrimental effect on academic-related outcomes. The findings come from low-quality to moderate-quality studies (M?=?60.62%; SD?=?10.44). Classroom-based dynamic seating could be a simple, effective health strategy to reduce students’ static sitting time without compromising student learning and academic performance. The current interventions need to be replicated with larger, adequately-powered RCT designs, valid and reliable outcome measures, and assessment of intervention fidelity.

     

Assessment Approaches and Cognitive Styles

The outcomes on multiple-choice tests and performance-based assessments for field-independent and field-dependent students were examined. A substantial interaction between cognitive style and assessment approach was found. Results suggested that performance-based assessment tended to favor field-independent subjects. Dependent on the purpose and intended use of assessment, this finding may raise concerns for validity based on either fairness or curriculum relevance.

理性实践下构建当代中国马克思主义信仰

构建当代中国马克思主义信仰要坚持理性实践,在变革理性思维中突破二元思维的局限,关注人本的内在向度,领悟生存的真正含义;在价值取向意义转变中认清价值原点和价值终点,将意义追寻转向为意义赋予;以安身立命的终极寄托领悟终极形上之道,在深度反问人生意义下自觉履行社会道义,通过理性实践思维确保马克思主义中国化真正同中国实际相结合。     

急性力竭性运动对大鼠淋巴细胞蛋白质组影响的初步研究

采用一次性力竭游泳为运动方式对大鼠进行训练,运动结束后取外周血,首先进行淋巴细胞计数,结果发现,运动组与对照组比较:CD4+细胞比值由28.6%±3.5%下降为21.4%±5.7%,CD8+细胞比值由14.7%±4.8%数目上升为23.8%±6.3%(P<0.01),CD4+CD8+由1.93±0.27下降为0.91±0.31(P<0.01),随即取淋巴细胞制备蛋白样品,进行双向电泳,银染显色,利用Pdquest软件对获得的蛋白图谱进行分析,结果发现共得到1546个点,能够匹配的有565个,不能匹配的有961点。在分子量43KD～97KD之间,运动组有部分蛋白质的量表现有较为明显增多,提示蛋白质表达的差异有可能是急性力竭性运动引发免疫机能下降的原因。
