Factor analysis techniques offer the communication researcher a set of important tools for the development and substantiation of attitude and opinion scales. Often, however, crucial factoring decisions are based on convention or misunderstanding, leading to questionable conclusions. The purpose of this article is to offer the nontechnical communication researcher a foundation for making and defending rational factoring decisions that can lead to quality scales. Basic concepts and recommendations are discussed regarding scale design, sample size and selection, number of variables, reduction and rotation methods, and factor retention criteria. A content analysis of 184 communication research studies from 51 communication journals that reported the use of exploratory factor analysis is included in order to determine common factoring methods and evidence of factoring decision rationales. Extending previous research that found inappropriate decisions or nonreporting of factoring decisions within studies in communication research and psychological research journals, this study demonstrates that factoring decisions in the broad community of communication journals is even less rigorous in these regards. 相似文献

The logic and procedures of causal modeling can help researchers avoid errors arising in more traditional analyses in a number of commonly occurring cases. A table of cases requiring causal modeling, or an equivalent technique, is presented. Nine years of published research in communication journals are reviewed to assess the adequacy of analysis in these situations. Standards for the conduct and reporting of causal modeling are also offered along with a review of their use in published causal modeling. These reviews indicate a number of areas demanding increased methodological rigor and sophistication in communication research. 相似文献

为了定量研究中国英文科技期刊在我国科学研究和出版交流活动中所发挥的作用,借鉴语言学研究中对某一个语言"交际价值"的定量测度方法,设计出评价中国英文科技期刊交流价值的新指标Q。它的定义由3部分组成,即期刊所在学科的英文流行度P、在学科内期刊的学术影响中心度C、期刊学术影响的国际扩散度D。若以这3个指标构成三维坐标系,每种期刊看作是从点0出发的一个向量,则指标Q的含义可以理解为期刊向量的长度。通过对45种中国英文科技期刊样本的实际计算,发现交流价值Q可以从一个方面以较好的区分度和准确性体现中国英文科技期刊的实用价值。 相似文献

This study explicates the indirect process through which news media use influences political participation. Specifically, it investigates the role of political knowledge and efficacy as mediators between communication and online/offline political participation within the framework of an O-S-R-O-R (Orientation-Stimulus-Reasoning-Orientation-Response) model of communication effects. Results from structural equation modeling analysis support the idea that political knowledge and efficacy function as significant mediators. In addition, results expound the increasing importance of the Internet in facilitating political participation. Implications of findings, limitations of this study, and suggestions for future research are discussed. 相似文献

The purpose of this article is to explore the use of mixed methods research (MMR) in articles published in library and information science (LIS) journals in Sub-Saharan Africa (SSA) from 2004 to 2008. A mixed methods research framework provided in the methodological literature is used to determine how this method was practiced within the LIS scientific community in SSA. Six hundred and eighty five articles published in nine peer-reviewed LIS journals in SAA were reviewed, finding the dominant research methods in these journals to be survey designs and historical research. The use of MMR was limited: 48 out of 685 articles used the mixed methods approaches that were identified in the methodological literature. A paradigm shift and a change of mindset are recommended for LIS researchers in SSA so that they may exploit the advantages offered by mixed methods research in conducting their studies. 相似文献

Is communication and media research a deeply international field? Are there real and extensive collaborations between various cultures represented on the highest level? In our current research, we analyzed the most recent 620 articles written by 1456 authors and published in 63 SCImago Scopus Q1-ranked journals in communication and media studies (CMS) to reveal the patterns of scientific contribution, the well-connected network of winner-countries, and the sporadic presence of loser or Matthew-countries. We used CATMA and Gephi software to analyze and visualize the distribution patterns behind scientific publications. Our results show that the network of collaboration in CMS is very sparse, most of the scientific publications are written by authors from a very few winner-countries, and the real loser of the field is obviously the CEE region with its lonely, disconnected, and marginalized representatives. 相似文献

This article provides a primer of the statistical technique called parceling, or aggregating items and using those aggregates as indicators of latent constructs, for structural equation modeling (SEM). First, two major types of parceling (subset-item-parcel and all-item-parcel approaches), alongside the traditional item-based approach, are illustrated. Second, both pros and cons of parceling are explicated. Parceling provides psychometric and modeling-related benefits. Risks associated with parceling are also noted. Particularly, potential induction of estimation bias and model misspecification are pointed out. In relation to the latter problem, unidimensionality of the scale is highlighted as an important prerequisite for the use of parceling. Finally, issues of the number of parcels per factor and parcel-building algorithms are discussed. Forming three parcels per factor by the random algorithm is recommended. Suggestions and general guidelines for the use of item parceling for SEM are also provided. 相似文献

This study evaluated the sampling methods and sample populations used in all U.S.-based survey and experimental mass communication studies published between 2000 and 2014 in six major journals (N = 1,173). Most studies used nonprobability samples, and more than half used student samples. Experiments used more nonprobability and student samples than surveys. Funded studies used more probability and nonstudent samples than nonfunded studies. Implications of results pertaining to population validity and interpretations of findings for mass communication research are discussed. 相似文献

Citation analysis provides valuable information on researchers' information use behavior, and helps librarians make evidence-based collection development decisions. However, no citation analysis of faculty publications in the field of communication has been performed to study communication researchers' information use behavior. This study examined communication faculty publication from 2006 to 2014, analyzing format, age, most frequently cited journals, and their subject areas. Analysis of local holdings provides evidence for the library's role in support of faculty research, and helps librarians articulate the value of libraries. 相似文献

In recent decades a distinctive literature has accumulated discussing the role of gender, feminism, and women's studies‐related research (GFWS) in the communication field; however, questions have persisted about how this research is represented in the field's publications. Contributing to the literature on the sociology of the field's scholarship, the history of the GFWS literature was sketched in a field test of a concept mapping technique that tracks patterns of publication and isolates conceptual associations within the titles of GFWS articles. The data for the study were significant concepts extracted from titles of 31,500 articles appearing in 70 communication journals and annuals within the period 1970 to 1997. The study accomplished several goals. First, it examined the accuracy of historical arguments about GFWS scholarship, arguments that bear on the issue of fair treatment of GFWS scholarship within the field. Second, it examined GFWS articles by publication source to assess patterns of representation by journal. Third, it provided a response to requests by some scholars working in the area for a thorough survey of the dimensions of the GFWS literature. Findings support the idea that GFWS scholarship is represented by a unique constellation of conceptual relationships. Feminist scholarship is found to have a history unto itself separate from that of studies of gender or sex differences, and has entered the literature in two distinctive eras. As well, feminist research was found to have a unique and uneven pattern of representation in the field's literature. By identifying threads of theoretical connection between articles in a widely dispersed literature, the concept mapping methodology is argued to provide one means for offsetting the fragmentation of the discipline's scholarship that has occurred throughout the last three decades as a result of the rapid proliferation of new specialized communication journals. 相似文献

Research methods are applied in all kinds of studies, though no consensus exists regarding what constitutes a research method and how research methods should be categorized. Over 1900 research articles were obtained from three major journals published between 2001 and 2010 in library and information science (LIS). Each selected article was coded using a schema of research methods developed in this study. The coded data, along with related publications, were analyzed qualitatively and quantitatively. This exploration shows that research methods comprise data collection techniques (e.g., interview, observation) and data analysis techniques (e.g., qualitative, quantitative). Research methods should perhaps be categorized by data collection technique, as it makes more sense than if research methods are labeled as qualitative or quantitative. This study is one of the many efforts to facilitate a better understanding of research methods in LIS and help scholars make more informed decisions about research method selection in their endeavors. Its implications can be extended to LIS research education, training, and advocacy. Because research methods themselves are not discipline-specific, researchers beyond the LIS field would benefit from this study as well. 相似文献
