近一段时期。中国互联网产业发生了新一轮的并购运动。人们关注的视线又一次被拉回到了中国互联网市场。作为并购方的各大网站与作为被并购方的目标网站均对并购行为期望颇高。然而作为资本运作的一种典型方式。并购的市场风险不可避免地伴随其积极作用而存在。并购双方依然面临价格风险、经营管理风险、行业产品风险等等不确定因素的困扰。如何确定目标网站。如何在并购后对双方资源进行有效整合都事关并购行为的成败。分析此次并购的起因及风险。并寻求规避风险的有效方法便成了当务之急。 相似文献

研究范式是数字化语境下信息科学基础理论研究的重要内容。信息科学是具有多元研究范式的常规科学,不同研究范式之间彼此关联,有可比性。本文在文献调研的基础上论述信息科学三种典型研究范式的基本观点和最新进展。系统/物理范式与信息论和技术传统关系密切,忽视信息用户和理论基础的适用性问题已成为该范式受到争议之所在。认知范式作为系统/物理范式的替代性范式而兴起,其科学共同体的发展趋于成熟。针对认知范式中社会维度的缺失,整体主义认知观等理论模型的提出使认知范式更加完善。领域分析范式重视认识论方法,强调社会文化情景的重要性,提倡从知识领域和话语社群角度开展研究。指出应从元理论层次比较信息科学各研究范式的基本理论假设与预设立场,构建从不同视角阐述社会信息现象的多元研究范式结构框架。 相似文献

Although the impact of time pressure on integrative problem solving has been widely explored in traditional negotiation research, little attention has been paid to its effect as organizational newcomers negotiate and coordinate work role expectations with supervisors. This study examines the effect of time pressure on three integrative communication dimensions of supervisory role negotiations: directness, elaboration, and mutual concessions. One hundred seventy employed college undergraduates completed survey items pertaining to recalled supervisory discussions of role expectations. Consistent with the hypotheses, time pressure had a significant positive effect on each of the communicative dimensions of the recalled negotiation. 相似文献

With the proliferation of the Internet and World Wide Web applications, people are increasingly interacting with government to citizen (G2C) eGovernment systems. It is therefore important to measure the success of G2C eGovernment systems from the citizen's perspective. While general information systems (IS) success models have received much attention from researchers, few studies have been conducted to assess the success of eGovernment systems. The extent to which traditional IS success models can be extended to investigating eGovernment systems success remains unclear. This study provides the first empirical test of an adaptation of DeLone and McLean's IS success model in the context of G2C eGovernment. The model consists of six dimensions: information quality, system quality, service quality, use, user satisfaction, and perceived net benefit. Structural equation modeling techniques are applied to data collected by questionnaire from 119 users of G2C eGovernment systems in Taiwan. Except for the link from system quality to use, the hypothesized relationships between the six success variables are significantly or marginally supported by the data. The findings provide several important implications for eGovernment research and practice. This paper concludes by discussing limitations of the study which should be addressed in future research. 相似文献

LibQUAL+® is an instrument purported to measure three dimensions of library service quality: service affect, library as a place, and information control. After changes were made to the instrument in 2003, however, no confirmatory factor analyses have been published in peer-reviewed journals affirming the three-factor structure of LibQUAL+®. These deficiencies were addressed by testing the hypothesized three-factor structure and the stability of that structure over time. Specifically, data from three samples (n = 550; n = 3261; n = 2103) were collected over a five-year period and analyzed using a multi-group confirmatory factor analysis. Results suggest that the theoretical model fit the data across the three samples and demonstrates factorial invariance over time. Multicollinearity between affect of service and information control, however, indicate that service quality may be measured as two dimensions rather than three, providing a more parsimonious explanation of service quality. 相似文献

The LibQUAL+ instrument serves as an indicator of user satisfaction. While offering clear insights into user satisfaction levels, it lacks interpretability when seeking to judge overall library success. This study aims at adopting LibQUAL+ as a measurement tool to predict library users' intention to patronize the library more in future. A theoretical model is presented to measure the relationships among the three LibQUAL+ service dimensions and the overall library user satisfaction. We estimate the effects of the three service dimensions on two indicators of students' attitudes and beliefs (Overall Satisfaction and Perceived Academic Success) and, in turn, the effects of those two variables on students' anticipated library use. We tested the research model using structural equation modeling. Our study results reveal that the three dimensions, Library as Place, Affect of Service and Information Control have considerably different impact on Satisfaction and Perceived Academic Success. Similarly, the two mediating variables, Satisfaction and Perceived Academic Success, have different impact on the Intention to Use [the] Library More in future. Our work is meant to explain how an effective and widely used measurement tool can become more effective and informative through SEM analysis and to provide a broader model to predicting library success. 相似文献

Information system success has been widely discussed in the past two decades. As systems and technologies are being improved and developed, discussions on their effectiveness and evaluation on their success have been continuously debated by researchers, scholars and practitioners throughout the years. Besides the major concern of IS effectiveness, factors influencing IS effectiveness are also important. One of these factors is the organizational factor. Using perceptual measures, this study aims to investigate the influence of organizational factors on MIS success. Survey questionnaires were gathered from 132 Extension Managers from Iran's Agricultural Extension Providers. Seven items were identified to influence MIS success. They are IS department structure, top management support, management style, managerial IT knowledge, goal alignment, resources allocation and IS infrastructure. The study also identified five MIS success dimensions; systems quality, information quality, perceived Ease of use, organizational impact and individual impact. The study found that the MIS success variables are significantly and highly correlated. The study also found all the organizational factors are significantly correlated to the five IS success factors investigated; the system quality, information quality, perceived ease of use, organizational impact and individual impact. Multiple regression analyses also found goal alignment as the highest predictor of IS success, followed by IS department structure, IS infrastructure and management style. 相似文献
