The purpose of this research is to analyse empirically how the use of Internet at the various stages of e-procurement impacts the organisational structure of the buying centre in terms of size and composition for a capital good. In this high-risk situation organisational buyers typically undertake extensive, deliberate choice processes involving numerous sequential phases. Interdepartmental coordination is required to specify, amongst others, the most suitable type of equipment in terms of capability, maintainability or costs. Information and communication technologies have changed the way we interact and communicate at different levels, amongst individuals within a single organisation as well as amongst different organisations (for example, with suppliers). A survey was performed using a questionnaire sent to a sample of industrial firms from different sectors. Results show that the size and composition of the buying centre varies at the different stages of the e-procurement process and that the use of Internet leads to an increase in the number of functional areas that intervene in the buying centre. The aims and implications for managers and researchers are discussed.  相似文献

The present study investigates the performance of persons with reading disabilities (PRD) on a variety of sequential visual-comparison tasks that have different working-memory requirements. In addition, mediating relationships between the sequential comparison process and attention and memory skills were looked for. Our findings suggest that PRD perform worse than normally achieving readers (NAR) when the task requires more than a minimal amount of working memory, unrelated to presentation rate. We also demonstrate high correlations between performance on the task with the most working-memory demands and reading-related skills, suggesting that poor working-memory abilities may be one of the underlying mechanisms of dyslexia. The mediating model analysis indicates that order judgment tasks are mediating to verbal working memory, suggesting that visual sequence memory precedes auditory sequence memory. We further suggest that visual tasks involving sequential comparisons could probe for poor working memory in PRD.  相似文献

This article explores how an alternative multichannel management strategy can improve the way governments and citizens interact. Improvement is necessary because, based on empirical data from various sources, the conclusion can be drawn that there is a gap between the communication channels governments prefer and those that citizens prefer. Governments may be too much guided by rational arguments like the cost efficiency of channels while citizens may choose channels depending on, e.g., task characteristics, personal characteristics or situational factors. In order to close the existing gap and to increase understanding about how different channel types may be positioned in multichannel management, this article proposes an alternative multichannel management strategy that takes both the citizen’s and the government’s perspective into account. This strategy is based on differences in channel types and channel modes via which governments and citizens interact.  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
