论网络环境下图书采编工作的转变

图书馆采编工作是文献资源的收集、整理、数据加工的职能部门。网络化的发展,使得图书馆采编工作发生了转变,原来的传统采编工作已不能适应时代发展的需要,取而代之的是利用计算机、网络为工具的现代图书采编工作。本文主要针对其采访、采购、编目工作的新变化做了具体阐述。     

Performance impacts of management in Korean schools: Testing the Meier and O’Toole model

This article investigates the impact of management on performance in Korean schools. Drawing upon the model of Meier and O’Toole, we test the linear relationships of internal management, managerial networking, and managerial quality with multiple dimensions of performance. We also examine the nonlinear relationships between networking and performance. The results show a general consistency in the positive link between management and performance, providing evidence to support the key arguments from the model. Still, there are noticeable differences in specific findings. As one of the first applications of the Meier and O'Toole model in Asia, this study illustrates the importance of the national context in management–performance linkage.     

Global Cities in Process of World Economy Net-Working and Transnationalization

Cities play a key role in the modem global economy. They became full-fledged （together with states, multinational corporations, and international economic organizations） subjects of international economy relationships; concentrated financial and commodity markets, enormous productive and innovative potential of humanity. The main reasons of transformation of economic importance of cities are their advantages in comparison with State economic systems. Labor and capital in urban economy systems are more mobile and productive; cities are more predisposed to create and commercialize innovations. Moreover, cities are easier to connect with international markets and world trade, which are able to reduce transport costs, to increase own investment attractiveness, and to rapidly form new types of business activities and forms of manufacturing organization. This study analyzes a current system of global cities, an intensity of inter-cities relationships, a potential of global urban system transformations in a future.     

Sharing travel stories and behavioral outcomes: A case of travel

The benefits of tourism have been drawing a great deal of attention from tourists, community, and society alike. This study investigates how tourists' story sharing activities influence their post-purchase behavioral process, depending on different communication conditions. Two 2x2 between-subject experiments were conducted with recent travelers in the U.S. Results reveal tourists' post-purchase behavioral processes depend on what, how, and with whom they engage in post-trip story sharing activity. Findings contribute to the literature on purchase-driven happiness, self-enhancement, well-being, and communications by providing evidence on how different communication conditions alter the effects of tourists' story sharing on their post-purchase behavioral outcomes. Findings also suggest that destination marketers should apply strategies to encourage tourists’ story sharing activity.     

Has Mumsnet changed me? SNS influence on identity adaptation and consumption

Abstract

This paper seeks to assess how one SNS network may support ongoing processes of identity adaptation and explore the role of consumption references in identity negotiation on the site. Drawing on theories of the liminality of motherhood, and the identity reconstruction processes that emerge in online communities, this paper traces the complexity of identity adaptation on SNS. With focus on SNS as a platform that may enable different phases of liminality, the transition to reincorporation phase is explored, revealing how members may experience support for ongoing identity renewal. Adopting a qualitative approach and direct observation method, posts from 12 extensive mumsnet.com discussion threads were screened and analysed using qualitative content analysis. Findings show how the functionality of this SNS site may facilitate some identity reconstruction.     

Knowledge sharing and firm performance: the role of social networking site and innovation capability

This study developed a framework to explore SNSs' capability as a strategic platform from which firms can overcome environmental turbulence and develop higher level knowledge sharing and firm performance output. The moderating effects of two types of innovation capability, product development capability and operational capability, were taken into consideration. We propose that SNSs' capability paired with strong product development capability is the key to improving knowledge sharing performance. SNSs' capability paired with strong operational capability can improve firm performance by advancing incremental innovation processes. Drawing upon the literature regarding information systems, knowledge management, and firm innovation, we propose a conceptual model adopted from the environment-strategy-performance framework to explore how these key factors interact to determine the fate of a firm.
