The present study attempts to develop a scale of students' general satisfaction with college instruction, to empirically assess the dimensions behind the scale, and to examine four predictors (sex, major, school year, and academic performance) which may affect the various factors of student's satisfaction with instruction. The study was conducted in two universities, one in Israel and one in the United States. The findings of this study indicate that the concept of students' satisfaction is composed of four factors and that each of these factors is best predicted by a different combination of the independent variables. However, academic performance is a dominant predictor of all four factors. The pattern of the findings is similar for both countries.The policy implications of these findings for university decision making and institutional research are discussed and elaborated.  相似文献

The aim of this study is to better understand the prevalence, scope, and unique challenges of undergraduate and first year librarians over the last decade, through the use of quantitative and qualitative data from job listings, online surveys, and phone interviews. The findings indicate that there is very little consensus about what the undergraduate librarian does, how the work is structured on a daily basis, and how its goals are negotiated and assessed. Further, undergraduate librarians face a number of issues, including navigating vaguely defined responsibilities, establishing their professional credibility, and communicating their role within the library and to the university. Survey participants reported experiencing tension between the traditional (reference, instruction, collection development) and undergraduate-specific aspects of their duties, indicating that it is difficult for them to prioritize engagement and outreach. While the literature on blended librarianship anticipates some of these issues, undergraduate librarians are unique because they provide an intersection between broader higher education priorities and the academic library. The author stipulates that the lack of definition, strain, and the perception of undergraduate librarianship as an entry-level position is incongruent with the importance colleges and universities place on undergraduate student success.  相似文献

The FCC's proposal for Universal Service Fund (USF) reform proposes to replace current universal service funding programs with the Connect America Fund (CAF), a fund devoted to using government support to make broadband service available in un-served or under-served geographical locations. The goal is to maximize the bang-per-buck from available funds by looking at incremental upgrades to existing infrastructure in under-served areas and incremental infrastructure build-outs in un-served areas. The strategy is to encourage competition between broadband providers whether they are wireless providers or wireline providers.  相似文献

This paper describes a methodology for the development of a proactive balanced scorecard (PBSCM). The balanced scorecard is one of the most popular approaches developed in the field of performance measurement. However, in spite of its reputation, there are issues that require further research. The present research addresses the problems of the balanced scorecard by utilizing the soft computing characteristics of fuzzy cognitive maps (FCMs). By using FCMs, the proposed methodology generates a dynamic network of interconnected key performance indicators (KPIs), simulates each KPI with imprecise relationships and quantifies the impact of each KPI to other KPIs in order to adjust targets of performance.  相似文献

This paper presents system design challenges and issues with sensing through walls at different standoff distances and wall types. Efforts for developing sense through the wall (STTW) systems, such as those undertaken by the US Army Technology Objective (ATO) program, aim at providing the soldier with situational awareness information before breaching a building in a military operations in urban terrain (MOUT) environment. STTW capabilities also support law enforcement and search and rescue applications. Since 2002, extensive evaluations of STTW technologies, most notably those performed by the Communications Electronics, Research, Development and Engineering Center (CERDEC) Intelligence and Information Warfare Directorate (I2WD), have been made to determine which technology could be the most viable solution. After conducting comprehensive studies, I2WD initiated several Phase I efforts and Phase II efforts. The purpose behind both efforts was to develop various STTW technology demonstrators under a 5 year ATO. Many lessons learned during the development of Phase I systems were incorporated into the considerations for Phase II developments. This paper discusses design challenges and issues with sensing through walls at different standoff distances and wall types through lessons learned and results from modeling and simulations performed by the Army Research Laboratory.  相似文献

This paper presents a literature review of empirical research related to the use and effect of online social annotation (SA) tools in higher education settings. SA technology is an emerging educational technology that has not yet been extensively used and examined in education. As such, the research focusing on this technology is still very limited. The literature review has aimed at presenting a comprehensive list of SA empirical studies not limited to a particular research method or study domain. Out of more than 90 articles that were initially found, only 16 studies met the inclusion criteria. Among the included studies were eight experimental or quasi-experimental studies and eight evaluation/survey studies. The SA empirical research has provided some evidence regarding the potential effectiveness of integrating social annotation tools into learning activities. Findings from the gathered literature were synthesized to provide recommendations for using SA technology in educational settings.  相似文献

A survey and analysis of the use of ethnographic methods in studies of libraries and library users identified a total of 81 studies. Five main types of ethnographic research methods were identified: observation, interviews, fieldwork, focus groups, and cultural probes. The survey shows a recent increase in the use of ethnographic methods in libraries, and identifies an emerging genre of studies associated with library planning that uses rapid ethnographic methods to investigate libraries and their users as part of planning processes. The survey supports comparison across ethnographic studies, settings, and methods; enables the growth of ethnographic methods as a research method in libraries; and provides material for library and information science curriculum development in this area. A bibliography of the studies used in the analysis is provided in Appendix A, and includes a number of gray literature reports and online publications.  相似文献

Many occupations, including librarianship, require emotional labor, which can be defined as the awareness of the emotional expressions required of a job, and the strategies used to express those emotions. To date, little research has examined emotional labor in library work, even though strong evidence exists to suggest emotional labor is a key component of many library jobs. Research on emotional labor shows that there can be positive and negative effects on individuals such as job satisfaction and job burnout. Research also shows that the negative outcomes from emotional labor may be buffered to some extent by factors such as support from the organization, or job autonomy. Individual differences such as personality traits and attitudes toward customers also impact the effects of emotional labor on employees. Because emotional labor is a critical issue in library work, and because evidence suggests positive outcomes can be fostered, there is a need to study how emotional labor is carried out in libraries, and to identify management techniques for emotional labor that will yield positive outcomes for both employees and organizations. Empirical research on emotional labor is reviewed, and a research agenda for exploration of this important construct in the field of librarianship is presented.  相似文献

Large scale open-source library automation systems can increase efficiencies in bibliographic production. The implementation of such a system, Evergreen, was examined in order to ascertain whether it facilitated detection and use of library collections in Indiana public libraries. Three hundred forty-nine participants recruited from nine public libraries completed user surveys. Additionally, library server data about interlibrary loan (ILL) statistics were collected from participating libraries on a monthly basis. The self-reported user survey included questions about patron history at local public libraries, use of the previous Online Public Access Catalogs (OPACs), and use of the Evergreen OPAC for finding and accessing multiple library collections since library users could directly request interlibrary loans via the Evergreen OPAC. The findings indicate that the implementation of the Indiana Evergreen system received moderately positive ratings from the participants; the positive evaluation was primarily related to the use of the ILL function. The ILL service satisfied the participants' needs and motivated them to use the Evergreen OPAC. Benefits for Evergreen users were confirmed.  相似文献
