This study tested competing predictions about the implications of Internet use for traditional inequities in social support availability. Using survey data collected as part of the Pew Internet and American Life Project, inequities in social support availability stemming from demographic and network-related factors were examined among non-users, Internet users, and Internet users who also participated in a social network site (SNS). The results offered evidence consistent with the social compensation perspective. Traditional inequities in support availability related to age, race, and total network size persisted among respondents who did not use the Internet, but were less evident or absent among Internet users and/or Internet users who participated in an SNS. Using the Internet to connect with others appeared to be an important mechanism through which inequality in support availability was mitigated.  相似文献

This study examines the metaphorical language of three managers in a Northwest city government. Four communication specialists used an interpretative method to identify, categorize, and rate perceptions of metaphors in three 30‐minute transcribed interviews. The results establish a set of metaphor categories, support a theory of culturally‐shared metaphors, demonstrate managers' differences in metaphor use, and suggest an association between managers metaphor use and subordinate ratings of effectiveness.  相似文献

Translation as an organizational activity is critical to the effective functioning of many institutions and is becoming ever more commonplace as our society grows increasingly multilingual and culturally diverse. This study examines translation in terms of its influence on organizational members' sensemaking and consequent social and task functions of the institution. An integrated theory of translation provides a foundation for identifying three major categories of problematics involving translation in workplaces: inaccuracies, losses of common sociocultural contexts, and changes to power relationships. Data from a hotel business meeting in which an executive's discourse in English were simultaneously translated into Spanish is analyzed to illustrate the problematics and to derive guidelines for organizations with multilingual workforces.  相似文献

Samford University Library conducted a study to determine correlation between library use and student achievement. This research used electronic resources as a measure of library use and grade point average as an indicator of academic success. The data demonstrate that students with higher GPAs tend to use library online resources more and with a higher frequency than those with lower GPAs. While this does not prove that use of online resources leads to a higher GPA, it provides strong evidence that the two are positively correlated for some populations. This study provides persuasive evidence of the library's contribution to the academic success of students.  相似文献

An informationist taught, consulted, and mentored graduate students enrolled in a graduate research project course in Health Informatics. An observational cohort study was conducted to determine the effect of an early (first term) and continued (subsequent term) exposure of course-integrated instruction, individual consultations, information resource mentoring, and educational collaboration partnership on the development of information literacy, research skills, and integrative competencies in graduate students. Student progress was assessed by survey, class performance, and faculty feedback. The course-integrated lectures, consultations, mentoring, and educational partnership between the informationist and academic advisors increased the students’ course performance, information literacy, and research skills in graduate students.  相似文献

The problem of how to rank academic journals in the communication field (human interaction, mass communication, speech, and rhetoric) is one of practical importance to scholars, university administrators, and librarians, yet there is no methodology that covers the field's journals comprehensively and objectively. This article reports a new ranking methodology based in empirical criteria. The new system relates independent measures of the prestige of the field's doctoral departments to information about where faculty members from those departments have published scholarly articles. This new approach identifies the field's most influential journals as those that more frequently publish the work of the field's top scholars and programs as perceived by their peers. This system was used to compute prestige weights (P-weights) for 65 communication journals. P-weights were found to be strongly correlated with ISI Web of Science journal impact factor scores and can be used to identify an overall prestige hierarchy for communication journals as well as prestige rankings by subject specialty.  相似文献

Although the effectiveness of inoculation as a strategy for promoting resistance to attitude change is fairly well established, the potential of inoculation messages to offer cross-protection for related, but untreated, attitudes warrants additional attention from scholars. The reported study tested the “blanket of protection” conferred by inoculation. Participants (N = 118) were randomly assigned to read an inoculation message addressing a target topic and subsequently had their attitudes toward three related, but untreated, topics attacked. The results offer some evidence that inoculation messages can confer cross-protection for related attitudes. Participants in the inoculation condition reported greater perceptions of threat, greater counterarguing, and less attitude change in response to attacks than participants in the control condition for two of the three untreated topics. Counterarguing in response to attacks on untreated attitudes appears to be primarily responsible for cross-protection.  相似文献

This article reassesses The People's Choice by Paul Lazarsfeld, Bernard Berelson, and Hazel Gaudet, one of the foundations of communication and voting behavior research. As with most classics, which are often cited but seldom read, we believe this book has much to teach contemporary social scientists. We return to the original context of the research and use voting data from the period with three broad goals: (a) to find ideas and lessons from this work that generally have been overlooked, (b) to suggest new ways of applying these ideas, and (c) to encourage scholars to engage more with this seminal work to understand ideas that are often overlooked when a complex piece of research is reduced to a brief discussion or passing citation.  相似文献
