Complementary roles of care and behavioral control in classroom management: The self-determination theory perspective     

Youyan Nie  Shun Lau 《Contemporary educational psychology》2009

This study examined how classroom management practices—care and behavioral control—were differentially associated with students’ engagement, misbehavior, and satisfaction with school, using a large representative sample of 3196 Grade 9 students from 117 classes in Singapore. Results of hierarchical linear modeling showed differential relations. After controlling for students’ gender and socioeconomic status, both care and behavioral control were positively related to student engagement. Moreover, behavioral control was a significant negative predictor of classroom misbehavior and care was a significant positive predictor of satisfaction with school. Our findings underscore the importance of blending care and behavioral control to achieve multiple goals of classroom management.  相似文献   

Gastric carcinoma with osteoclast-like giant cells: a case report and review of the literature     

Li-duan Zheng  Xiu-ping Yang  Hua-xiong Pan  Xiu Nie  Jun He  Qing Lv  Qiang-song Tong 《Journal of Zhejiang University. Science. B》2009,10(3):237-241

Gastric carcinoma with osteoclast-like giant cells (OGCs) is an extremely rare tumor. So far, only six cases have been reported in the literature. Here we report an additional case of this tumor in a Chinese 78-year-old man presented with abdominal pain, vomiting, and hematemesis. Physical examination and gastroscopy revealed a tumor in the gastric antrum. The biopsy and pathological findings indicated a gastric adenocarcinoma with OGCs, which were present in both the tumor and the metastatic lymph nodes. Further immunohistochemical staining indicated that OGCs were reactive with CD68, CD45, and vimentin protein, but not with pancytokeratin, carcinoembryonic antigen, or epithelial membrane antigen, suggesting the monocytic/histiocytic derivation of these OGCs. In situ hybridization for Epstein-Barr virus showed no nuclear positivity in either adenoearcinoma or OGCs. Postoperative follow-up showed that the patient had survived for at least 6 months without recurrence. Further investiga-tion is warranted to clearly define the prognostic significance of OGCs in gastric carcinoma.  相似文献

试论校报总编的“总编意识”     

聂松义  王晓云  王晓磊 《思想政治教育研究》2009,25(2):115-117

要办好校报,必须努力提高办报人的角色意识,着力培养办报人的专业素质和办报理念,使之承担起高校主流媒体的职责。校报要更好地发挥喉舌、桥梁、纽带和舆论导向作用,在读者群中产生理想效应,需要校报总编能以较强的主体意识去担负主导作用。而校报总编要完成新时期总编角色的转换,尤应牢固树立包括责任意识、党性意识、专家意识、创新意识、全局意识、前瞻意识、服务意识、精品意识等八种意识在内的“总编意识”,确立新的认知范式,坚持追求自我培养和不断提升,以增强校报的活力,向办报的更高境界迈进。  相似文献

Identification of ambiguous queries in web search     

Ruihua Song  Zhenxiao Luo  Jian-Yun Nie  Yong Yu  Hsiao-Wuen Hon 《Information processing & management》2009

It is widely believed that many queries submitted to search engines are inherently ambiguous (e.g., java and apple). However, few studies have tried to classify queries based on ambiguity and to answer “what the proportion of ambiguous queries is”. This paper deals with these issues. First, we clarify the definition of ambiguous queries by constructing the taxonomy of queries from being ambiguous to specific. Second, we ask human annotators to manually classify queries. From manually labeled results, we observe that query ambiguity is to some extent predictable. Third, we propose a supervised learning approach to automatically identify ambiguous queries. Experimental results show that we can correctly identify 87% of labeled queries with the approach. Finally, by using our approach, we estimate that about 16% of queries in a real search log are ambiguous.  相似文献
