Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“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
FACTORS INFLUENCING STUDENT’S INTENTION TO USE E-LEARNING SERVICES: AN APPLIED STUDY ON LEBANESE PRIVATE UNIVERSITIES
Get PDFThe study’s purpose is to investigate the impact of selected factors (Computer self-efficacy (CSE), subjective norms (SN), perceived enjoyment (PE), perceived usefulness (PU), perceived ease of use (PEOU), attitude) on university students’ intention to use e-learning. The objective of this paper is to advance a conceptual framework to better understand the factors that could affect the intention of students to use e-learning in Lebanese universities. The collection of the data was from 444 private universities students in Lebanon. The SEM analysis had been used to assess the influence of these components to intend e-learning system. All proposed relationships are accepted in the framework expected the relationships between Computer self-efficacy (CSE) and subjective norms (SN) on perceived usefulness are rejected. In addition, relationships between subjective norms and perceived enjoyment on perceived ease of use (PEOU) are rejected. Finally, results are discussed then conclusions and future research are presented
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Get PDFWe 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
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
Competitive Advantage and Performance, The Role of Value and Rareness of Resources and Capabilities: The Case of Lebanese SMEs
Get PDFThis research aims to examine the competitiveness and the strategic behavior of the Lebanese SMEs, through their possession and exploitation of strategic resource-capability combination attributes. A sample of 285 Lebanese SMEs were obtained through the use of a survey questionnaire and the non-probability sampling to collect primary and quantitative data. The results show that for Lebanese SMEs, not all resources-capabilities are of equal importance when creating competitive advantage. They indicate that only organizational resource-capability combinations are considered as strategic assets and related to differentiation advantage, financial resource-capability combinations are only considered as strategic assets and related to cost advantage, and that cost and differentiation advantage are both related to performance.There were some problems concerning the data collection due to the fact that the Lebanese SMEs owners are not familiar with the research. In fact, this study may have positive implications on the Lebanese SMEs managers’ decisions, where this study can be considered as a guideline that will help them revise their strategic choices, behaviors, capabilities and resources, vis-à-vis of competition and to readjust their strategy if it does not work well. Indeed, the value of this research is that it is the first to empirically study the Resource-Based View in Lebanon from the Lebanese SMEs context, which is considered as suitable context, given its crucial contribution to the whole economy. It is one of the rare studies that reflects SMEs challenges and problems that inhibit them from improving their performance.

TAM EXTENSION IN E-LEARNING SYSTEM APPLICABLE IN PRIVATE UNIVERSITIES IN LEBANON
Get PDFThe paper’s purpose is to investigate the influence of selected elements (Accessibility, personal innovativeness (PI), resistance to change, facilitating conditions, perceived usefulness (PU), perceived ease of use (PEOU), attitude) on university students’ to intend e-learning usage. The objective of this paper is to advance a conceptual framework to analyze and to recognize the intention of students to use e-learning in Lebanese private universities. The collection of the data was from 444 private universities students in Lebanon. The SEM analysis had been used to evaluate the influence of these components to intend e-learning system. The results stated that relationships between accessibility on perceived usefulness are not accepted. Furthermore, the associations between (PI) and PEOU are also not accepted. However, all other relationships are accepted in the framework model. Finally, results discussed then conclusions and future research are presente
