Philadelphia at the time of the founding of the Medical Library Association (MLA) is described. Several factors that promoted the birth of the association are discussed, including the rapid increase in the labor force and the rise of other health related professions, such as the American Hospital Association and the professionalization of nursing. The growth of the public hygiene movement in Philadelphia at the time of Sir William Osler's residency in the city is discussed. Finally, the rapid growth of the medical literature is considered a factor promoting the development of the association. This article continues the historical consideration of the MLA begun in the author's article on the three founders of the association. The background information is drawn from the items listed in the bibliography, and the conclusions are those of the author. 相似文献

This study examines cable system diversification into three nontraditional services: pay-per-view television, high-speed Internet access, and telephony. An econometrics model based on the Industrial Organization Model is used to explore the factors that have led to variation in diversification among cable systems. Specifically, this study examines how three sets of variables, namely, cable system characteristics, market structure, and market demographics, influenced cable system diversification. Multiple linear regression was performed to identify the determinants of cable system total degree of diversification, which is defined to be the number, from 0 to 3, of the three nontraditional services offered by a cable system. Regression results indicate that Multiple System Operator (MSO) ownership, the number of basic cable service subscribers, and the number of broadcast television stations receivable over the air all had a statistically significant positive relationship to cable system total degree of diversification, whereas the number high-speed Internet service providers in a cable franchise area had a statistically significant negative relationship to cable system's total degree of diversification. 相似文献

Big data promises to transform public decision-making for the better by making it more responsive to actual needs and policy effects. However, much recent work on big data in public decision-making assumes a rational view of decision-making, which has been much criticized in the public administration debate. In this paper, we apply this view, and a more political one, to the context of big data and offer a qualitative study. We question the impact of big data on decision-making, realizing that big data – including its new methods and functions – must inevitably encounter existing political and managerial institutions. By studying two illustrative cases of big data use processes, we explore how these two worlds meet. Specifically, we look at the interaction between data analysts and decision makers. In this we distinguish between a rational view and a political view, and between an information logic and a decision logic. We find that big data provides ample opportunities for both analysts and decision makers to do a better job, but this doesn't necessarily imply better decision-making, because big data also provides opportunities for actors to pursue their own interests. Big data enables both data analysts and decision makers to act as autonomous agents rather than as links in a functional chain. Therefore, big data's impact cannot be interpreted only in terms of its functional promise; it must also be acknowledged as a phenomenon set to impact our policymaking institutions, including their legitimacy. 相似文献

AbstractNational bibliographies have been identified as a crucial resource for historical research on the publishing landscape, but using them requires addressing challenges of data quality, completeness, and interpretation. We call this approach bibliographic data science. In this article, we briefly assess the development of book formats and the vernacularization process in early modern Europe. The work undertaken paves the way for more extensive integration of library catalogs to map the history of the book. 相似文献

The internal effects of the Nicaraguan revolutionary reconstruction, 1979–1989, are compared and contrasted with the portrayal of these effects in a sampling U.S. government documents. Special attention is given to U.S. Department of State documents aimed at influencing public opinion. That the revolution had some clearly positive effects on Nicaraguan society is concluded, but weaknesses and contradictions in the ideology and the programs of the revolution are exposed. It is suggested that much contemporaneous U.S. government information on the topic served a propagandizing function. 相似文献

This paper sets the problem of development of information culture and advances the hypothesis about understanding of the meaning of information as its basis. Five ideas related to the problems of the paper are distinguished in the theory of understanding. The paper describes the concept of adequate and inadequate understanding the meaning of information and develops the criteria of understanding the meaning of information. The concept of the “understanding of the meaning of information” is defined. 相似文献

Many researchers have assumed that social media will reduce inequalities between elite politicians and those outside the political mainstream and that it will thus benefit democracy, as it circumvents the traditional media that focus too much on a few elite politicians. I test this assumption by investigating the association between U.S. Representatives using Twitter and their fundraising. Evidence suggests that (1) politicians' adoptions of social media have yielded increased donations from outside their constituencies but little from within their own constituencies; (2) politicians with extreme ideologies tend to benefit more from their social media adoptions; and (3) the political use of social media may yield a more unequal distribution of financial resources among candidates. Finally, I discuss the implications of these findings for political equality, polarization, and democracy. 相似文献
