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
Change Management and Sustainable Growth Rate : Evidence of the Banking Sector in Angola between 2013 and 2023
Get PDFEffective change management creates value for firms prepared to respond to market challenges robustly and forthrightly to gain competitive advantage. This study identifies the role of effective change management in promoting the capabilities of firms to remain sustainable and resilient amid economic crises. After engaging with the concept of crises and change management, this study analyses the banking sector in Angola with a particular focus on commercial banks. The financial statements of banks were scrutinised over the period between 2013 and 2023 with a view to determine the Sustainable Growth Rate (SGR), which is considered an indicator of sustainability and resilience. Only four banks managed to successfully navigate through the roller-coaster period of crisis with a positive SGR throughout the period of analysis. This case study attempts to bridge theories and praxis to inform both scholars and practitioners. The study concludes by identifying four important contributions and suggesting opportunities for further research and application
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
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
An exploration into the understanding of Leadership Ethos and Critical Success Factors in public management: The case of the Department of Trade and Industry, South Africa and the Ministry of National Economy in the Democratic Republic of the Congo.
No full textPhilosophiae Doctor - PhDThis dissertation assumes an explorative and descriptive approach rather than a
comparative approach. It aims at offering the concept of Leadership Ethos (LE) and its
inherent Critical Success Factors (CSFs) as a paradigm in the quest to secure organisational
efficiency and effectiveness in public management, with a particular focus on the public
policy implementation process.
It begins by presenting the background to the study, providing relevant information about
the problem and the methodology followed. It then introduces the context of the problem
of the study, sketching the context of civil service leadership before the advent of
democracy in the Republic of South Africa (RSA) and prior to independence in the
Democratic Republic of the Congo (DRC). These two countries serve as the case study
through the Department of Trade and Industry (DTI) and the National Ministry of Economy
(ECONAT) respectively. This is followed by the presentation of the theoretical framework
of the study, defined within the context of compliance-based and integrity-based
approaches to leadership, resulting in discussions on leadership theories. This leads to an
examination of public administration reforms (PARs) in the context of LE, illustrating how
PARs have resulted in a change in organisational focus and culture of the public sector.
The study examines relevant economic policies in the RSA and the DRC with a view to
illustrate the effects of LE and its subsequent CSFs on performance in public management,
in particular, with respect to the implementation of public policies. Data were then
presented and analysed with the purpose of probing the understanding of LE and its
inherent CSFs. It considers how LE enhances organisational efficiency, which in turn will
enhance social transformation, by guaranteeing the successful implementation of economic
policies. The study then presents a summary of the main findings in both case study
research areas. In its conclusion, the study proposes recommendations towards a LE that
contributes to more effective public policy implementation processes
In search of an appropriate leadership ethos: a survey of selected publications that shaped the Black Theology movement
No full textMagister Theologiae - MThThe understanding and practice of leadership in Sub-Saharan Africa, in all spheres, is at the heart beat of this work. Questions and concerns over the quality of leadership in most countries in this particular region are reasons which have led to revisit and investigate the formative training of the current cohort of African leadership with a special focus on the ethical aspect of leadership. It is an assumption, in this thesis, that the contemporary cohort of African leadership received their formative training especially in the 1960s and 1970s and that they were deeply influenced by the black consciousness movement and, in association with that, by the emergence of black theology. In this respect, this research project explores the notions of ethics and leadership with a view to determine ways in which an appropriate leadership ethos was portrayed and articulated in the writings of selected exponents of the black theology movement, namely ML King (Jr), Desmond Tutu and Allan Boesak. The purpose of this work is therefore mainly descriptive: to map discourse on a leadership ethos in the context especially of black theology.South Afric
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
