The economic returns to field of study and competencies among higher education graduates in Ireland     

Elish Kelly  Philip J. O’Connell  Emer Smyth 《Economics of Education Review》2010,29(4):650-657

This paper looks at the economic returns to different fields of study in Ireland in 2004 and also the value placed on various job-related competencies, accumulated on completion of higher education, in the Irish labour market. In examining these issues, the paper also analyses, through quantile regression, how the returns vary across the earnings distribution. The impact that education-job mismatch, both education level and field, has on earnings is also taken into consideration. The results derived indicate that, relative to the base case, there are higher returns to Medicine & Veterinary, Education, Engineering & Architecture, Science and Computers & IT. Small but significant returns were found for some of the competencies analysed, in particular technical skills. The quantile regression analysis reveals that both field and competency returns vary across the wage distribution and that, apart from Medicine & Veterinary and technical skills, field and competency-specific returns diminish as one moves up the earnings distribution.  相似文献

Exploiting Hierarchy in Text Categorization   总被引：4，自引：3，他引：1  

Andreas S. Weigend  Erik D. Wiener  Jan O. Pedersen 《Information Retrieval》1999,1(3):193-216

With the recent dramatic increase in electronic access to documents, text categorization—the task of assigning topics to a given document—has moved to the center of the information sciences and knowledge management. This article uses the structure that is present in the semantic space of topics in order to improve performance in text categorization: according to their meaning, topics can be grouped together into meta-topics, e.g., gold, silver, and copper are all metals. The proposed architecture matches the hierarchical structure of the topic space, as opposed to a flat model that ignores the structure. It accommodates both single and multiple topic assignments for each document. Its probabilistic interpretation allows its predictions to be combined in a principled way with information from other sources. The first level of the architecture predicts the probabilities of the meta-topic groups. This allows the individual models for each topic on the second level to focus on finer discriminations within the group. Evaluating the performance of a two-level implementation on the Reuters-22173 testbed of newswire articles shows the most significant improvement for rare classes.  相似文献   

Personal digital assistant-based drug information sources: potential to improve medication safety.     

Kimberly A Galt  Ann M Rule  Bruce Houghton  Daniel O Young  Gina Remington 《Journal of the Medical Library Association》2005,93(2):229-236

OBJECTIVES: This study compared the potential for personal digital assistant (PDA)-based drug information sources to minimize potential medication errors dependent on accurate and complete drug information at the point of care. METHODS: A quality and safety framework for drug information resources was developed to evaluate 11 PDA-based drug information sources. Three drug information sources met the criteria of the framework: Eprocrates Rx Pro, Lexi-Drugs, and mobileMICROMEDEX. Medication error types related to drug information at the point of care were then determined. Forty-seven questions were developed to test the potential of the sources to prevent these error types. Pharmacists and physician experts from Creighton University created these questions based on the most common types of questions asked by primary care providers. Three physicians evaluated the drug information sources, rating the source for each question: 1=no information available, 2=some information available, or 3 = adequate amount of information available. RESULTS: The mean ratings for the drug information sources were: 2.0 (Eprocrates Rx Pro), 2.5 (Lexi-Drugs), and 2.03 (mobileMICROMEDEX). Lexi-Drugs was significantly better (mobileMICROMEDEX t test; P=0.05; Eprocrates Rx Pro t test; P=0.01). CONCLUSION: Lexi-Drugs was found to be the most specific and complete PDA resource available to optimize medication safety by reducing potential errors associated with drug information. No resource was sufficient to address the patient safety information needs for all cases.  相似文献   

为植物鉴定和学习科学建立词表     

Jane Greenberg Bryan Heidorn Stephen Seiberling Alan S. Weakley 《现代图书情报技术》2006,(1):33-43

北卡罗林纳大学植物语言研究课题组（University of Noah Carolina Plant Language Team，UPLanT）根据学生和一般公众学习植物科学知识的特点，提出了建立植物学语言工具，为学生及一般公众充分利用网络上的植物科学信息提供方便．本文探讨了词表的含义，辨别植物的关键，植物分类表以及用于植物鉴别的描述性词汇。文中还介绍了U-PLanT的研究开发活动和当前研究方向，本课题组开发了一系列词表工具，包括技术性的植物词汇、学生植物学字典、植物描述概念表、植物学辞典以及UNC-OpenKey植物词汇。该文的一个重要内容是介绍了U-PLanT开发植物学词表的做法，具体包括（1）确定现有的词表；（2）评价它们的可用性及是否经济；（3）修改；（4）改造现有词表使之适用于检索环境；（5）实施；（6）测试评估；（7）再修改等7个步骤。这个项目主要是为了缩小学生和科学家之间词汇上的差别，帮助学生更好地利用数字化科学教育资源。  相似文献   

A successful cross-training experience of reference service at UCLA     

Carr AF  Kawakami AK 《Medical reference services quarterly》2002,21(2):15-19

This paper describes a successful cross-training and reference librarian exchange experience involving two librarians at UCLA, one based at the Louise M. Darling Biomedical Library and the other based at the College Library, which primarily serves undergraduates. The experience has increased the reference skills and expertise of both librarians by introducing them to new sets of reference tools and databases, and has broadened their network of colleagues within the UCLA Library system. The participating libraries have also benefited from the exchange, and the program is expanding to include other UCLA libraries.  相似文献
