公共事业综合管理系统的设计与实现

J2EE是目前比较流行的企业应用开发技术,B/C架构也是目前的信息系统架构的主流选择.本文主要介绍基于J2EE的B/S架构的公共事业综合管理系统的设计与实现.     

基于J2EE技术的教务处办公系统的研究与实现

通过对清华大学教务处办公管理现状和需求的分析研究,设计并实现了一种整合Struts和Hibernate框架的基于J2EE平台的教务处办公系统,实现了教务处日常行政办公的网络化和数字化,构建了面向处内的日常行政办公与信息交流、面向校内的信息服务、面向校外的宣传窗口三位一体的网络环境和平台.该系统结构清晰、功能丰富、职责明确、界面友好,并具有良好的可扩展性、实用性和可维护性.由于该系统所体现的三位一体的分层思想对其他办公系统具有较强的适用性,因此具有广阔的推广应用价值.

The determinants of school district salary incentives: An empirical analysis of,where and why

Most public school districts in the United States use a salary schedule to determine compensation for teachers within the district. However, some school districts have implemented incentive pay schemes that allow flexibility at the school or even individual teacher level. These compensation schemes in some ways may more closely approximate a competitive labor market. This study examines the factors that influence a district's decision to offer incentive pay using districts from the 1999 to 2000 Schools and Staffing Survey. The results suggest that school districts that face barriers to recruitment or retention and districts that face competition from non-sectarian private schools are more likely to offer incentive pay.     

Faculty employment and R&D expenditures at Research universities

This study uses panel data to examine the relationship between faculty employment and external R&D expenditures at Research and Doctoral institutions over a 15-year period of time. On average, a 1% increase in the number of full-time faculty is associated with about 0.2% increase in total R&D expenditure. Further, a one percentage point increase in the share of full-time faculty members that are not on tenure-track lines is associated with a decrease in total external R&D expenditure by about 0.6%, suggesting that full-time faculty that are tenured or on tenure-tracks are the main category of faculty that generate external R&D funding. Further, our results suggest that an increasing usage of part-time faculty, holding constant the institution's full-time faculty size, boosts an institution's external R&D expenditures. On average, a one percentage point increase in the share of part-time faculty members is associated with a 0.44% increase in the total external R&D expenditures. Increases in graduate student enrollments are associated with increases in external R&D expenditures. Finally, an institution's external R&D expenditures are significantly influenced by both the amount of its own institutionally financed research expenditures and the level of federal funding for research.     

Early gender test score gaps across OECD countries

The results reported in this paper contribute to the debate about gender skill gaps in at least three ways. First, we document the large differences in early gender gaps across developed countries using a large scale, modern, representative data source. Second, we show that countries with pro-female sorting, countries that place girls in classes with higher than average scores have smaller gender test score gaps, at least in math. Third, we show that the degree of academic tracking is correlated with observed gender gaps across developed countries.     

大连市健康人群J波发生相关因素的研究

研究健康人群J波发生率及与年龄、性别、劳动强度的关系。对2008年1月-2009年6月的1809名健康体检者的心电图进行分析,观察J波发生情况。结果表明,J波发生率5.64%,其中男性发生率明显高于女性（8.91%比1.40%,P〈0.05）;青壮年发生率较高;下壁导联发生率显著高于右心导联、左心导联（P〈0.05）;劳动强度越大,J波发生率越高。结论J波多发于男性、青壮年,多见于下壁导联,与劳动强度有关。     

论知识论与社会学在图书馆学中结合——基于对谢拉“社会知识论”的考察

图书馆知识性和社会性的统一要求知识论和社会学在图书馆学中的结合,并形成两种基于不同中心的结合模式。谢拉的“社会知识论”以社会学为中心,知识论在其中尽管具有重要的实践意义,却局限于传统立场。他的理论因此在实质上接近于“知识社会学”。引入个体知识论或社会学的规范性不能使之转变为社会知识论,应采取以知识论为中心,在其规范性中包含社会学因素的结合模式。     

The climate for entrepreneurship at higher education institutions

While the importance of a supportive context for entrepreneurship is widely acknowledged, its antecedents are rarely investigated. We apply the concept of organizational climate to higher education institutions and examine the drivers of students’ perceptions of the entrepreneurial climate in their university. Combining data from two unique datasets and using multilevel techniques, we analyze the relationship between university characteristics and such climate perceptions of 8009 students at public universities in Germany. We find university entrepreneurship measures to have a positive effect on students’ climate perceptions, which also depend on students’ background and gender. In addition, we find evidence for different peer effects, depending on students’ affinity for entrepreneurship. For the general student population, including entrepreneurship content in their normal studies seems to be required to initiate a social process of sensemaking. However, students’ perception of the entrepreneurial climate only depend to a certain degree on intentional entrepreneurship measures. In our study, general university characteristics have the strongest influence on climate perceptions. Overall, our study adds to our understanding of which parameters are important for establishing a more favorable and inspiring climate for becoming an entrepreneur at higher education institutions.     

Technology and employment: Mass unemployment or job creation? Empirical evidence from European patenting firms

This paper explores the possible job creation effect of innovation activity. We analyze a unique panel dataset covering almost 20,000 patenting firms from Europe over the period 2003–2012. The main outcome from the proposed GMM-SYS estimations is the labor-friendly nature of innovation, which we measure in terms of forward-citation weighted patents. However, this positive impact of innovation is statistically significant only for firms in the high-tech manufacturing sectors, while not significant in low-tech manufacturing and services.
