A cross-cultural evaluation of the psychometric properties of Information Seeking Anxiety Scale in Pakistani environment
No full textThis study investigated the psychometric properties of Information Seeking Anxiety Scale (ISAS) using
postgraduate students in a Pakistani university. A 47-item ISAS was administered to 297 students,
selected through stratified convenient sampling procedure, by visiting each department at the
university. An eighty-five percent response rate was achieved through usable returned
questionnaires. The principal component analysis (PCA) using varimax rotation yielded six-factor
solution to the Information Seeking Anxiety Scale (ISAS), namely, (1) Resource Anxiety(2) ICT
Anxiety(3) Library Anxiety(4) Search Anxiety(5) Mechanical Anxiet
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Strengthening Democracy with Information: An Assessment of Rural Dwellers’ Political Information Behavior
Full text linkThis study explored political information behavior of citizens residing in a rural setting from the district of Toba Tek Singh, Punjab-Pakistan. Qualitative research design using an unstructured interview guide was employed to conduct this research. Face-to-face interviews of 51 participants, selected through purposive sampling process, were conducted for data collection by visiting their homes using local language. Each participant was informed of his responses at the end of the interview for data verification and authentication. Each interview was carefully recorded and transcribed. Using thematic analysis, the verbal data were analyzed and multiple responses were grouped together and reduced into ‘information needs’ and ‘information channels.’ After that, the frequencies and percentages of the responses against these themes were counted because it was possible due to the uniformity in the qualitative data. The results indicated that a large majority of these participants were politically ignorant and did not seem to be in need of political information. A good number of participants required political information on current affairs, rural development policies, government policies and decisions, and both local and national political news. They mainly depended on mass media particularly television for political information followed by newspapers, radio, and interpersonal relationships. Since the rural dwellers were not interested in political information due to political ignorance and backwardness, efforts should be made to improve their political awareness. There was a critical need to evaluate the effectiveness and appropriateness of the existing information infrastructure for the rural population in Pakistan. The results will assist the policy makers in the development of a need-based, unified, and integrated rural information delivery system. This research would make a worthy contribution in existing research on information needs and seeking behavior of rural communities as no such study found addressing directly rural citizens’ political information behavior
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Evidence on Psychometric Properties of Scales Assessing Information Related Anxieties: A Systematic Review
Full text linkThis systematic review examined the evidence of psychometric properties of scales available in studies reporting surveys measuring information related anxieties such as library anxiety, information seeking anxiety, and information anxiety. A systematic search in four databases such as Web of Science, Scopus, LISA, and LISTA was carried out using the keywords \u27library anxiety\u27, \u27information anxiety\u27, \u27information seeking anxiety\u27, and \u27information seeking\u27 AND \u27anxiety\u27. This review included those studies reporting the use of any scale measuring information related anxiety published in the English language and included all type of documents (e.g. journal articles, conference papers, book chapters, theses/dissertations, research reports). The screening process resulted in 45 studies meeting the eligibility criterion. The extracted data included author names, year of publication, type of scale used, scale title, background, type of construct assessed, number of items in the scale, scale origin, studies reporting use, studies contributing psychometric information, scale availability, and psychometric properties reported. The results indicated nine instruments assessing information-related anxieties. The classical test theory was applied for eight instruments. No psychometric properties were reported for a single instrument. Most psychometric instruments were developed in the United States. Face/Content validity through experts, construct validity through exploratory and confirmatory factor analysis, and internal consistency reliability through Cronbach alpha was the most commonly used psychometric analysis. None of these studies applied the Rasch model of modern item response theory for psychometric examination. This review has serious implications on the inferences drawn by the practitioners and researchers based on the earlier assessment of information related anxieties. It suggests the development of standards for not only designing new psychometric tests but also for the use and reporting of such tests. This study contributes to the existing research on information-related anxieties by systematic reviewing the evidence of psychometric properties as no such study available so far
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
