Using telephone surveys of business/financial journalists in the United States (n = 200), this research investigates the agenda-building role of social media content in journalists’ work. Understanding that more non-public relations content from user-generated and social network sites, like YouTube and Twitter, are fast becoming resources for journalists to get story ideas, break scandals, and find sources, we began this scholarly work to determine the frequency of such uses of social media. Overall, findings indicate very little use of social media by these business journalists. Results and implications for public relations practitioners are discussed in detail. 相似文献

For past two decades many organisations have tried to implement integrated information management systems for better production management based on co-ordination of information and therefore activities of different departments. Although Enterprise Resource Planning systems have been in the market for the past decade, many industries find it difficult to implement such systems due to the amount of work involved in streamlining the documentation, customisation and of high costs reported in implementation. An attempt is made through this paper to propose an integrated model, which can be easily understood by production personnel, with specific emphasis on the textile sector. 相似文献

Abstract Much anecdotal material describes various human impacts of computer adoption within the social work profession, however, there is scant research which confirms or challenges these assumptions. This article describes a study which investigates the diffusion of computers into the social work profession in terms of empowerment as an individual outcome for workers. A questionnaire returned by 520 social workers provided data on organizational computer diffusion, organizational centralization, and the Social Worker Empowerment Scale. Workers in organizations where computer diffusion was more advanced, and those in more decentralized decisionmaking environments were found to be more empowered. 相似文献

AbstractDuring 2009, the Hilton M. Briggs Library, South Dakota State University, went live with MetaLib, a federated search engine from Ex Libris. This paper presents the implementation process, addresses resource accessibility issues, and suggests a number of resources that can be consulted about these issues. Readers can apply similar strategies to projects involving federated search systems, as many implementation projects involve the same basic considerations presented here. The author did not find any studies specifically focused on configurations of MetaLib resources, so this content should be singularly useful. 相似文献

In recent years, voter turnout has been decreasing in most industrial countries, and about 40% of all electors abstain from
voting. This may affect income inequality and the GDP growth rate through a redistribution policy determined by majority voting.
In this paper, we explore the reasons for this continuing decrease in voter turnout and assess its social costs. We conclude
that informatization lowers voter turnout by generating an information overload, and that a decrease in voter turnout lowers
GDP growth by limiting income redistribution.

For the first time, a new class of generalized Weibull linear models is introduced to be competitive to the well-known generalized (gamma and inverse Gaussian) linear models which are adequate for the analysis of positive continuous data. The proposed models have a constant coefficient of variation for all observations similar to the gamma models and may be suitable for a wide range of practical applications in various fields such as biology, medicine, engineering, and economics, among others. We derive a joint iterative algorithm for estimating the mean and dispersion parameters. We obtain closed form expressions in matrix notation for the second-order biases of the maximum likelihood estimates of the model parameters and define bias corrected estimates. The corrected estimates are easily obtained as vectors of regression coefficients in suitable weighted linear regressions. The practical use of the new class of models is illustrated in one application to a lung cancer data set. 相似文献

In comparison of treatments using homogeneous experimental units, it is shown that a design is Schur optimal when treatment replications are as equal as possible. 相似文献

Recent environmental problems have been caused by business activities and a lifestyle based on mass production, mass consumption and mass disposal. These problems have also become global in scale. Increasingly, global efforts are being applied to preserve and improve the environment. NEC, a worldwide electronics manufacturer, created its own environment action plan called Eco-Action 21. This is a continuously evolving plan applied throughout the NEC group and subsidiaries. Globally, 34 NEC manufacturing sites have received ISO 14001 certification. NEC Tohoku in Japan and NEC Ireland obtained BS 7750 certification even before this. NEC improves subcontractors' environmental behaviour with our accumulated expertize and technology derived from our ISO experience and our own development. Input for this paper was not only from NEC Tohoku and the NEC group, but also from outside NEC. 相似文献

In this article statistical inference is viewed as information processing involving input information and output information. After introducing information measures for the input and output information, an information criterion functional is formulated and optimized to obtain an optimal information processing rule (IPR). For the particular information measures and criterion functional adopted, it is shown that Bayes's theorem is the optimal IPR. This optimal IPR is shown to be 100% efficient in the sense that its use leads to the output information being exactly equal to the given input information. Also, the analysis links Bayes's theorem to maximum-entropy considerations. 相似文献
