People are increasingly viewing, providing, and recommending video content through the Internet. Applying the uses and gratifications framework, along with contextual age and generational theory, this study identifies and compares motivations for, and their influence on, traditional TV viewing and online user-shared video use among a U.S. sample of adult Internet users. Further, this study explores the form and role of audience activity through online user-shared video recommendations (type, channel, and social relation). Overall, the basic U&G motivations also apply to the new online media world, but differ in levels and influence. 相似文献

Getting help in understanding how to use and interpret a new information system is a crucial organizational and individual resource. Indeed, both informal and formal sources of information technology help are expensive and necessary, but largely unidentified, unmanaged, and underresearched. This study proposes that two types of factors influence the formation of information technology helping relationships: individual and structural. Based on a survey of employees in an organization implementing a new workstation‐based customer database system, the study compares influences on being sought as an informal source of IT help, and on types of help (individual or positional) that one seeks. One individual factor (some forms of computer expertise) and most structural factors (especially measures of employees’ perceived socialization, task interdependence, and communication networks) exerted weak but significant influences on employees’ IT helping relationships. 相似文献

The notion of what reference service ought to be continues to change as technology provides new ways to interact with users and alters their expectations of the library and librarians. As new tools for interaction become available, it is critical that librarians continuously evaluate their effectiveness at providing users with a valuable service that meets the needs of the community being served. By assessing tools and techniques in light of user expectations and satisfaction, librarians can come up with unique service programs that also incorporate their own knowledge and interpersonal skills. 相似文献

This article reviews research from 1980‐1995 exploring the relationship between principal leadership and student achievement. The focuses is on the substantive findings that emerged from the review. Earlier reports focused on conceptual and methodological issues. The general pattern of results drawn from this review supports the belief that principals exercise a measurable, though indirect effect on school effectiveness and student achievement. While this indirect effect is relatively small, it is statistically significant and supports the general belief among educators that principals contribute to school effectiveness and improvement. Moreover, the review suggests that previously described discrepancies in research results may be explained by the conceptual and methodological tools employed by researchers. We also emphasize the limitations of these studies. Even taken as a group they do not resolve the most important theoretical and practical issues concerning the means by which principals achieve an impact on school outcomes and how contextual forces influence the exercise of leadership in the schoolhouse. It is concluded that while substantial progress has been made over the past 15 years in understanding the principal's contribution to school effectiveness, the most important scholarly and practical work lies ahead. In addition to this qualified, we assert that scholars are better equipped conceptually and methodologically to address these challenges than in 1980. 相似文献

Introducing and studying two types of time series, referred to as R1 and R2, we try to enrich the set of time series available for time dependent informetric studies. In a first part we focus on mathematical properties, while in a second part we check if these properties are visible in real data. This practical application uses data in the social sciences related to top Chinese universities. R1 sequences always increase over time, tending relatively fast to one, while R2 sequences have a decreasing tendency tending to zero in practical cases. They can best be used over relatively short periods of time. R1 sequences can be used to detect the rate with which cumulative data increase, while R2 sequences detect the relative rate of development.The article ends by pointing out that these time series can be used to compare innovative activities in firms. Clearly, this investigation is just a first attempt. More studies are needed, including comparisons with other related sequences. 相似文献

Five ratios RH, RT, SH, ST and SZ derived from the three-part division of a set of sources in h-core, h-tail and uncited sources are defined. Dynamic changes in the three independent ratios RH, SH and SZ are studied for six selected topics. Data about these topics are obtained from the Web of Science for scientific papers and Derwent Innovations Index for technical patents. It is observed that all RH- and SH-values decrease when the time span widens, while SZ stays the same or increases; and that all RH- and SH-values for papers are larger than the corresponding values for patents. The shifted Lotka distribution is used in a theoretical interpretation of these empirical phenomena. 相似文献

Collaboration can be described using layered systems such as the article–author–institute–country structure. These structures can be considered ‘cascades’ or ‘chains’ of bipartite networks. We introduce a framework for characterizing and studying the intensity of collaboration between entities at a given level (e.g., between institutions). Specifically, we define the notions of significant, essential and vital nodes, and significant, essential and vital sub paths to describe the spread of knowledge through collaboration in such systems. Based on these notions, we introduce relative and absolute proper essential node (PEN) centrality as indicators of a node's importance for diffusion of knowledge through collaboration.We illustrate these concepts in an illustrative example and show how they can be applied using a small real-world example. Since collaboration implies knowledge sharing, it can be considered a special form of knowledge diffusion. 相似文献
