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
Friendly Outsider or Critical Insider?: An Action Research Account of Oxfam’s Private Sector Engagement
No full textNGOs increasingly engage with the private sector with the objective of addressing complex sustainability issues. Problems like poverty, deforestation, food security, and climate change cannot be managed by governments alone. In this scenario, collaboration between NGOs and the private sector regarding the creation of sustainability standards is an alternative with the potential to create innovative solutions through societal coordination and self-regulation. This study explores how NGOs can manage and leverage collaboration with the private sector as a strategy to accomplish their mission. Using an action research approach and empirical evidence from Oxfam Novib, the study analyses Oxfam's participation in the creation of certification standards and the strategies employed to articulate human rights principles therein. It also assesses the extent to which Oxfam’s private sector portfolio helps fulfill its theory of change and identifies the core organizational competencies required to manage private sector engagement. Furthermore, the study illustrates how Oxfam negotiates with and mediates between actors holding conflicting views about sustainability certification. Lastly, the research discusses the contributions of private sector engagement to carry out NGO goals, highlighting the inherent tensions and limitations that come with it
Making both ends meet
No full textSustainability of global supply chains has gained increased attention during the last decade. Although the focus of sustainable development originally implied environmental efficient practices, this notion developed into an emphasis on sound business social practices. The phenomenon of addressing sustainability practices in supply chains lead to a research focus on developing country practices that also take the perspectives of developed countries into consideration. This study is unique, as the challenges from the supply side are rarely brought into perspective of the global supply chain. The phenomenon of sustainable supply chains has become even more relevant in terms of global agricultural supply chains, bearing in mind the current debates on food security, poverty and advancement of developing countries. Developing countries increasingly rely on the international distribution of raw mineral resources and agricultural food produce to stimulate economic growth. As developing country, South Africa is dependent on such exports. This thesis empirically investigates specific challenges in the table grape export chain. The main focus is directed at the export of table grapes to the European Union, especially the United Kingdom and Netherlands as main importing countries. Our research question is formulated as follows: ‘What specific capacities of the South African table grape supply chain would be essential for the improvement of global trade and would assure the sustainability of production in South Africa?’ In the first part of this study we will focus on how supply chain actors perceive sustainability and their relationship to other actors in the chain. Furthermore, we report on challenges, problems and discrepancies found in the interrelationships between actors. The first chapter in this section, Chapter 2 is an exploratory study that gives an overview that defines challenges. The second chapter in this section, Chapter 3, relates to perceptions; it expands on factual information. Part two particularly discusses entrepreneurship and business management skills of growers on the supply side. The first chapter in this section studies the traditional entrepreneur. It evaluates which current management and farming skills and attitudes are in place, and the capacities that should be built to improve entrepreneurship on farms. The next chapter in this section, Chapter 5 takes the concept of empowerment on board. This chapter looks at success factors and capacities required to achieve empowerment. The third chapter in this section, Chapter 6, focuses on the environmental aspects and how changes can be made and capacity problems can be solved. In Part three, the demand side approaches are shown, which enabled us to obtain a holistic view of the export chain. The first chapter in this section, Chapter 7 discusses approaches applied by the demand side to bring sustainability change to the supply chain. Chapter 8 deals with the question how sustainability requirements are provided and the necessary information is exchanged as well as the implications for the supplying farmer. The last part consists of Chapter 9 and Chapter 10. Chapter 9, reports on the validations of our conclusions at the dissemination workshop and validating interviews with European retailers. The last Chapter, Chapter 10, brings our final conclusions, reflects back on the capacity problem and dimensions we defined in the first chapter and gives final perceptions of future developments in governance of sustainable supply chains
Celebrating diversity?: an empirical study of tensions between the discourses of assimilation and multiculturalism
Full text linkThe Netherlands boasts a wealth of ideological, cultural and religious philosophies, but the degree of freedom we have to experience cultural identity is up for public debate. The Muslim community in particular is experiencing a polarity between advocates of multiculturalism on one hand and followers of assimilation discourse on the other. This dissertation analyses the positions taken by different social players in the fields of politics, economics, and civil society. The results reveal that conflicts of interest make it difficult for politicians and halal certifiers to take a stand. The media facilitates the changing political debate by offering platforms to some players and not others

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
