Skipping class in college and exam performance: Evidence from a regression discontinuity classroom experiment     

Carlos Dobkin  Ricard Gil  Justin Marion 《Economics of Education Review》2010,29(4):566-575

In this paper we estimate the effect of class attendance on exam performance by implementing a policy in three large economics classes that required students scoring below the median on the midterm exam to attend class. This policy generated a large discontinuity in the rate of post-midterm attendance at the median of the midterm score. We estimate that near the policy threshold, the post-midterm attendance rate was 36 percentage points higher for those students facing compulsory attendance. The discontinuous attendance policy is also associated with a significant difference in performance on the final exam. We estimate that a 10 percentage point increase in a student's overall attendance rate results in a 0.17 standard deviation increase in the final exam score without adversely affecting performance on other classes taken concurrently.  相似文献

A pipelined architecture for distributed text query evaluation   总被引：1，自引：0，他引：1

Two principal query-evaluation methodologies have been described for cluster-based implementation of distributed information retrieval systems: document partitioning and term partitioning. In a document-partitioned system, each of the processors hosts a subset of the documents in the collection, and executes every query against its local sub-collection. In a term-partitioned system, each of the processors hosts a subset of the inverted lists that make up the index of the collection, and serves them to a central machine as they are required for query evaluation. In this paper we introduce a pipelined query-evaluation methodology, based on a term-partitioned index, in which partially evaluated queries are passed amongst the set of processors that host the query terms. This arrangement retains the disk read benefits of term partitioning, but more effectively shares the computational load. We compare the three methodologies experimentally, and show that term distribution is inefficient and scales poorly. The new pipelined approach offers efficient memory utilization and efficient use of disk accesses, but suffers from problems with load balancing between nodes. Until these problems are resolved, document partitioning remains the preferred method.

GaIN (Georgia Interactive Network for Medical Information) study on health professionals' search requests and continuing education needs

Health sciences librarians are being called upon to be more proactive in their institutions' continuing education efforts. In an effort to identify whether search requests indicated CE needs, a study was conducted by a group of members of GaIN (Georgia Interactive Network for Medical Information). MEDLINE requests from health care professionals for subject specific clinical topics were collected during a six-month period via a standard search request form created for the study. Copies of all completed requests were collected and broad ICD-9 codes assigned to the search topics. Institutional reports were generated for each participating library to share with hospital CE coordinators. They were also compiled for the group as a whole, and reflected the "hottest" topics requested during the study period for physicians and for non-physicians (nurses, allied health, administrators). A survey to hospital librarians and CE educators showed some value in the reports, but greater potential for further collaboration between librarians and CE coordinators.  相似文献   

运动员某些生理,生化指标的时间生物学特征探讨   总被引：1，自引：0，他引：1  

简坤林  周蓉晖 《成都体育学院学报》1995,21(1):91-96

对２６名男性运动员的环磷酸腺苷（ｃＡＭＰ）、环磷酸鸟苷（ｃＧＭＰ）、可的松（Ｃｏｒｔｉｓｏｌ）、睾丸酮（Ｔ）在２４小时内的不同时刻的量变的研究，以探讨其时间生物学特征，为运动员选材提供依据。结果发现ｃＡＭＰ、Ｃｏｒｔｉｓｏｌ、Ｔ均表现出明显的近似昼夜节律（Ｐ＜０．０５），ｃＧＭＰ不具有昼夜节律（Ｐ＞０．０５），ｃＡＭＰ的峰相位处于上午８时左右，Ｃｏｒｔｉｓｏｌ、Ｔ的峰相位与ｃＡＭＰ基本同步。可的松的节律稳定性好，可作为判定机能调整幅度的标志节律。  相似文献
