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
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
Cape Town clothing workers' attitudes towards key aspects of and alternatives to regulation by the Bargaining Council
No full textThe South African clothing industry has shed over 70 000 jobs in the last decade. This has given rise to huge debate in the industry and academia about the role of the bargaining council in regulating the industry as well as other factors such as trade liberalisation that are causing the industry to shrink. This study explores attitudes held by formal and informal clothing workers toward the regulatory environment and possible alternatives to current regulation by the bargaining council. The research aimed to explore worker understanding of the regulatory environment, in particular the wages versus job-security trade-off; to find out whether workers are aware of alternatives to the current wage model, such as performance-based incentive pay; to explore the attitudes workers hold toward home-based informal factories; and to assess the attitudes of workers to worker cooperatives. Using semi- structured face-to-face interviews, 24 respondents (ten formal and 14 informal workers) were selected to participate in an attitude survey that explored their feelings across attitudinal classes - cognitive, affective, and behavioural, using the non-probability purposive sampling technique. Research findings show that both sets of workers generally had a very poor understanding of the industry's regulatory environment. After receiving brief explanations of alternatives to regulation by the bargaining council, the workers understood them cognitively and attitudes varied between the two groups. All workers were generally against performance-based incentive pay because it requires them to place too much trust in employers. Informal work was viewed as a viable alternative although formal workers could not conceive joining informal firms. Both sets of workers expressed favour towards worker co-operatives, which have the advantage of changing the working relationship from manager and worker to worker as owner, thus empowering workers. All workers, however, demonstrated overall awareness of the pressures facing the clothing industry, such as those caused by cheap Chinese imports. The evidence is however, not sufficient to arrive at a set of conclusions regarding alternatives to regulation by the bargaining council
Why are there so few minimum service level agreements? A case study of a metropolitan municipality.
Get PDFIn terms of the South African Constitution, every worker has the right to strike. This right is regulated in the Labour Relations Act. Workers engaged in essential services are prohibited from striking. The prohibition does not apply if a minimum service level agreement, guaranteeing services in the event of a strike, has been concluded between employers and trade unions. The Essential Services Committee, established under the Labour Relations Act ( the Act), must ratify these agreements before they become effective. More than two decades after the LRA was promulgated, very few ratified minimum service level agreements have been concluded in the municipal sector. This study explores the reasons for this and suggests legislative and policy interventions that could be considered on a sector wide basis. The study is by way of a single-case study of a metropolitan municipality. Data were obtained from two sources: 14 semi-structured interviews with participants and from an analysis of documents relevant to the regulation of essential services. The study established that the legislative framework for regulating essential services in South Africa is consistent with the principles and decisions laid down by the International Labour Organisation. It however does not provide guidelines for determining minimum service levels. An apparent unevenness between the representatives of the negotiating counterparts exists in the municipal sector in South Africa. Many of the party representatives negotiating minimum service levels, do not work in designated essential services or possess relevant technical skills. The findings of the study suggest steps that could be taken to strengthen the capacity of the Essential Services Committee to assist parties in the municipal sector to conclude minimum service agreements and build the negotiating capacity of the parties. The study also makes recommendations regarding improved participation by essential service workers and the broader community in the process
Design houses in the Cape Town clothing value chain of production
No full textIncludes abstract.Includes bibliographical references (leaves 79-81).This exploratory study aimed to investigate the role that design houses play in the Cape Town clothing value chain of production. Semi-structured interviews were conducted with key informants, buyers in clothing retail companies, heads of design rooms in design houses, and homeworkers. Findings reveal that design houses act as intermediaries between retailers and clothing manufacturers or between retailers and homeworkers. In their latter role design houses are forging links between the informal and formal clothing economy. As in buyer-driven chains of production, retailers in the clothing value chain wield a substantial amount of power in determining prices. It was found that design houses are not completely powerless in their relationship with retailers, in fact, they posses knowledge that enables them to bargain over prices. The relationship between design houses and homeworkers was found to be an oppressive one, with homeworkers possessing little to no bargaining power. The increase in the number of design houses in Cape Town has assisted in the survival of the industry in the face of a number of difficulties. The continued presence of design houses creates the potential for development in the industry
The politics of regulation and the South African sex industry : an interest group analysis of power and civic participation in public policy on adult commercial sex work
No full textIncludes bibliographical references (leaves 155-159).This dissertation is an interest group analysis of power and civic participation in public consultations on adult commercial sex work1 and legal reforms in South Africa. It determines the interests, the strategies and tactics2 employed, as well as power relations between interest groups in the social policy process as led by the South African Law Reform Commission (SALRC). The research study solicits answers to the following research question: What is the role of power and civic participation in public policy on adult commercial sex work and how does the distribution of power shape policy outcomes
Reclaiming state power to bridge governance gaps in global trade
No full textIncludes bibliographical references.An astute understanding of history is not required to grasp that global trade is not a new phenomenon. As a very young student in American schools, I still recall learning about the caravans of traders trekking across the Silk Road, about the merchant traveller Marco Polo, about the misplaced aspirations of Christopher Columbus and the resulting Columbian Exchange between Europe and the Americas. This is an oft-mythologized and sometimes flatly fabricated period of history,1 but there are basic truths at the base of it all. There were certainly men embarking on difficult journeys across vast ocean stretches, carrying goods from one continent to another with the hope of striking it rich (or at least making enough to buy themselves a good time at the next harbour). There were certainly people who profited, and plenty more who were exploited. But while global trade is not new, the structure and volume of global trade has changed drastically during recent decades. More money is at stake, and so is a greater swath of humanity. Complex global value chains2 have sprouted, in which a single product may contain fingerprints from dozens of countries when it finally lands on retail shelves. In this dissertation I am concerned with the fate of workers that toil anonymously at the base of these global value chains. But my primary focus is to contest a myth, though it has nothing to do with Christopher Columbus. Rather, the dominant narrative surrounding contemporary global trade suggests that regulation of such is beyond our reach. Due to the evolving structure of global trade, ‘governance gaps’ have emerged. This begs many questions: Who is responsible for achieving a remedy when things go wrong, when a factory collapse kills hundreds of workers or when the makers of high-priced fashion aren’t paid a living wage? Do we turn to the state that shelters the corporation, even if the wrongdoing occurs outside their jurisdiction? What about the state where the operations are based? Can they impose their will on corporations that are sheltered elsewhere? Are the corporations themselves responsible, even when they are not directly involved in outsourced operations? Are local manufacturers at fault if they are acting at the behest of a more powerful entity
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
