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
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
Rethinking competency requirements in South African supply chain management
Full text linkBackground: In the realm of talent acquisition and supply chain management (SCM), the establishment of a standardised competency framework is pivotal. However, a lack of consensus in the supply chain management literature persists regarding the prioritisation of competencies for SCM professional recruitment in South Africa. This necessitates a re-evaluation of SCM competencies to align with the dynamic business environment.
Objectives: To understand the competencies necessary for supply chain professionals in South Africa’s SCM job market to inform curriculum development for the training of supply chain profession at higher education institutions.
Method: A qualitative, grounded theory approach was followed. Content analysis was conducted on 29 SCM job advertisements posted on various employment agents’ websites. Atlas was then used to create codes and code groups and themes describing the SCM job market needs and expectations.
Results: While technical competencies maintain their significance, strategic thinking and cognitive capabilities are increasing in their importance compared with interpersonal skills in the SCM job market.
Conclusion: The required competencies for SCM roles are evolving, with an increasing emphasis on strategic and cognitive skills rather than just technical abilities. Interpersonal competencies, although still important, are becoming less crucial. Training institutions should adjust their curricula to ensure well-rounded SCM professionals.
Contribution: The literature reflecting the fast evolving nature of SCM competencies is sparse. This study challenges the prevailing narrative that emphasizes technical and interpersonal competencies thereby opening new pathways for curriculum development and professional training of SCM professionals
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
Value chain management practices and value creation in sub-Saharan African apparel firms
Full text linkPurpose: This study explores value chain management (VCM) practices in the sub-Saharan African apparel industry, developing a strategic framework to enhance value creation.
Design/methodology/approach: A quantitative research design was adopted, surveying 430 managers across the apparel value chain. Data were analysed using factor, correlation, and regression analyses to ascertain the impact of VCM practices on value creation. However, it is essential to notice that the study’s findings are limited to the sub-Saharan African context and may not directly apply to other regions.
Findings/results: The analysis revealed a strong correlation between specific VCM practices, such as information sharing, incentive realignment, agile manufacturing, and value creation. These practices help firms to navigate the industry’s complexities and leverage regional opportunities.
Practical implications: The study provides a valuable framework for managers, highlighting customer-centricity and strategic sourcing strategies. These strategies are crucial for enhancing operational efficiency and competitive positioning in the global market.
Originality/value: The study offers original insights by empirically validating VCM practices and their contribution to value creation within the sub-Saharan apparel sector. The strategic framework fills a gap in the literature and aids the sector’s integration into the global value chain
