There are three reasons why probability samples often become separated from their putative populations in mass communication research. First, researchers sometimes believe populations must surely exist when in fact they do not exist. Yet they relentlessly pursue these phantom populations rather than heed classic warning signs that something is wrong. Second, researchers often struggle with underpowered samples. Rather than render those samples using more appropriate qualitative methods, they plow ahead using misapplied statistical methods and thus never inferentially connect to a population. Third, researchers frequently and incorrectly use random assignment rather than random selection as a sample method. This, in turn, can leave a sample unconnected to a population if the population can be drawn only through random selection. As obvious as these three errors are, researchers nonetheless stumble into them regularly. We examine why that is and what researchers can do to avoid these errors. 相似文献

Academic journals have traditionally provided disciplinary forums for scholarly communication (i.e., vetting, legitimating, and disseminating new ideas). Digitization is affecting scholarly communication and academic journals. Two effects are the bundling of journals by publishers and the growing variety of formats that open up new avenues of dissemination. Both effects have disrupted the traditional roles and relationships of scholars and their institutions, publishers and libraries in the processes of scholarly communication, including the significance of academic journals as a format. 相似文献

A content analysis of rap music videos aired on BET, MTV, and VH1 examined the occurrence of controversial themes, gender differences, and skin tone distortion. The results of this study found that current rap music videos have placed an emphasis on themes of materialism and misogyny. Additionally, men and women in the videos differ in their portrayal of these themes. Specifically, female characters are significantly more likely to appear as objects of sexuality. Men and women also differ in their appearance with more African American females appearing to have Eurocentric features. Implications and suggestions for future research are discussed. 相似文献

This study explores the library instructional programming and resources of high school library media centers in western Montana with the intent of documenting and understanding both the services provided to and the experiences of first-year college students at the University of Montana. Results from the survey (n = 22) and site visits (n = 10) reveal wide variation in the levels and types of library instructional programming provided at the library media centers, including media specialists’ perceptions of high school students’ information literacy skills. However, consistency was seen in the media specialists’ collection management strategies and in collection content. The results suggest implications for first-year library programming and highlight opportunities for further 9–16 collaboration and study. 相似文献

Recent writing on the subject of ethnography has sought to examine the field not only as a place where research is carried out, but also as a methodological construction. While this writing emphasizes the extent to which people's experiences of community and culture can no longer be necessarily understood in relation to geographically based locations, it often continues to assert the "legacy of the field" (Clifford, 1997, p. 88) and its accompanying expectations and practices. In this article, I draw on my experience of doing ethnographic research in the textual community of 'zines in order to challenge the assumption that ethnographic fieldwork is necessarily dependent on physical displacement, and face-to-face encounters with our research participants. Specific attention is paid to the epistemological and ethical issues that emerge when one chooses to carry out research in textual communities. Intentionally foregrounding the parallels between the textual community of 'zines and the virtual communities associated with the Internet, this article also raises important questions for ethnographers carrying out research in networked environments. 相似文献

In an attempt to address shortcomings revealed in international assessments and lamented in legislation, many schools are reducing or eliminating elective courses, applying the rationale that replacing “non-essential” subjects with core subjects, such as mathematics and language arts, will better position students in the global market. However, there is evidence that systematically pairing a core subject with another, complementary subject, may lead to greater overall learning in both subjects. In this paper, we analyze two subject area pairs—first and second language, and computer programming and mathematics—to demonstrate in what ways two subjects might complement each other. We then analyze the relationships between these pairs to better understand the principles and conditions that encourage what we call convergent cognition, the synergistic effect that occurs when a learner studies two complementary subjects. 相似文献

This report describes the design and conduct of a statewide training needs assessment based on joint state agency and university planning. Sample findings are presented for both the statewide population (N = 736) and various job function groupings. Differences in expressed training needs across job function groups are examined, and strategies for providing effective and efficient training are discussed. 相似文献

Phonological skills and comprehension failure: A test of the phonological processing deficit hypothesis 总被引:2,自引:1,他引:1
Shankweiler and colleagues argue that text comprehensionproblems in young children arise from phonological processingdifficulties. Their work has focused on children with poor wordreading ability. We investigated this hypothesis for children whoexperience comprehension difficulties in the presence of age-appropriate word reading skills. We found that good and poorcomprehenders performed comparably on various measures ofphonological processing and differed on a task that made greaterdemands on working memory, Bradley and Bryant's odd-word-outtask. In a final study, hierarchical regression analyses supportedthis distinction: the odd-word-out task was a strong predictor ofreading comprehension performance even after IQ, vocabulary and single word reading had been controlled for, but a lessmemory-dependent phonological task was not. These studiessupport previous work which indicates that poor comprehenders'problems arise from higher-level processing difficulties. 相似文献

Investigating the causes of reading comprehension failure: The comprehension-age match design 总被引:1,自引:0,他引:1
The reading-level (or reading-age) match design has become a widely-used tool for investigating the possible direction of the relation between particular skills and word reading ability: Cause or consequence. This paper outlines an analogous method for identifying candidate causes of reading comprehension failure, the `comprehension-age match design' and discusses the strengths and limitations of this design. 相似文献
