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
MAPPING PATTERNS AND IDENTIFYING CONCEPTUAL FRAMEWORKS IN GLOBAL HEALTH RESEARCH: A SYSTEMATIC REVIEW
Get PDFBackground: Global health is a complex, interdisciplinary, and contested field. It is rapidly growing and undergoing ideological and methodological changes. Despite many theoretical claims over what global health research ought to be, there are few empirical reports on what global health is, as a present field of research. The aim of this study is to: 1) determine patterns in global health research, based on key research characteristics; and 2) determine relationships between these characteristics to identify and define conceptual frameworks in global health research. Methodology: A systematic review of research in global health journals was conducted for papers published in the years 2010, 2015, and 2020. Categorical data on 17 research characteristics was extracted from all studies included in the analysis. The relationships between these characteristics was analyzed and visualized using multiple correspondence analysis, as implemented in the R’s ca package. Significance tests of independence determined relationships between pairs of variables. Results: The final analysis was done on 1033 included studies from 14 journals. 56% of the studies used a quantitative observational methodology. While 82% of research had at least one author affiliated with a high-income country, 96% of research funded (at least partially) by the Bill & Melinda Gates Foundation had at least one author affiliated with a high-income country. There was a significant relationship between the use of social and structural determinants of health and the authors’ affiliations (X2=59.06, p < 0.001), with the use of social and structural determinants of health lower among lower-income authors than high-income authors. The first and second dimensions of multiple correspondence analysis explained 38% of the variables’ deviation from independence. Conclusion: Multiple correspondence analysis offers a novel way of understanding global health research, contributing empirical data to the discourse on what lies ahead for the field of global health. The relationship between the use of social and structural determinants of health, authorship, and research methodologies point to the need for important conversations on the direction of global health research, starting from where we are at now.ThesisMaster of Science (MSc)While the importance of the field of global health is more prominent than ever, it is a field of uncertainty, controversy, contested merit, and often disreputable history. Conversations abound on the strengths and weaknesses of the field and what needs to change; yet, there is a lack of empirical grounding for these discussions. In this study, I reviewed global health research literature, identifying 17 key characteristics that surface in theoretical conversations on global health, and scored 1033 global health research studies according to these characteristics. Using multiple correspondence analysis, the 17 characteristics were analyzed together and visualized to elucidate the relationships between the characteristics. I found that: over half of the studies were quantitative observational; most research in global health had at least one author from a high-income country; and middle-income authors were less likely to study social and structural determinants of health than high-income authors. These findings lend important empirical evidence to conversations on the direction of the field, starting from where we are at now
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
The Epistemic Validity Of Empathy
Get PDFThis paper is written in special acknowledgement and recognition of oppressed minority groups including, but not limited to, those of Black, Indigenous, and Asian persons. All lives do not matter until Black, Red, and Yellow lives matter.Obama once spoke of his desire to see empathetic individuals appointed to the position of Supreme Court Justice of the United States. His desire was met by many with resistance as people voiced concerns regarding the unreliability of beliefs founded on empathy and possible negative consequences that may come about. Concerns regarding unreliability are the product of our inability to access the ‘privileged information’ or the actual thoughts and perspectives of those we intend to empathize with. Attempts to form empathic beliefs, in the absence of this information, could lead to various harms to the very groups we intend to empathize with. Stereotyping, bias, and claims of sincerely ‘knowing’ the unique circumstances of those very different from ourselves can all lead to the justification of actions with harmful consequences.
In my thesis I wish to address these concerns by acknowledging that most practical sources of knowledge (those we make use of and depend on regularly), such as those predicated on notions of cause and effect, have similar risks associated with them. Theories such as gravity and evolution remain theories and yet via the establishment of best practices and diligent communities, we are able to minimize the dissemination of false knowledge claims and their respective harms. In my paper I acknowledge this and explain how empathy can be dealt with in a similar fashion, while also reducing potential harms to others and allowing us to take advantage of the many benefits empathic knowledge has to offer. In the same way that we still continue to make use of our understanding of gravity to improve our lives and society by building aircrafts, we can make use of empathy to improve the ability of individual social and moral agents, as well as society as a whole. Under this pragmatic approach even the legal system can reap the benefits of empathic knowledge claims, so long as we, moving forward, work to collectively discern how to best ensure the validity of empathic knowledge claims.ThesisMaster of Philosophy (MA)Obama once spoke of his desire to see empathetic individuals appointed to the position of Supreme Court Justices of the United States.

Food Sovereignty: An Emancipatory Human Right
Get PDFThe globalized neoliberal agricultural regime operates within a neocolonial context and was therefore built upon the ideologies, law, and legacy of the colonial-era. Both capitalism and colonialism, in theory, and in practice, share characteristics that are inherently contrary to the realization of human rights. Given that the human rights framework operates within a globalized capitalist economy, there are systemic barriers to the universal realization of human rights. This thesis holds that the concept of food sovereignty not only highlights this reality but presents a nuanced emancipatory path forward towards a post-capitalist world where universal human rights realization is not only possible but inherent to the functioning of food sovereignty itself. Food sovereignty presents as a praxis for Marxist agrarian theory in establishing an approach to closing the metabolic rift. The existence of the Food Sovereignty Movement also confirms the existence of the metabolic rift as the theoretical disconnect between capitalism and human rights which underpins the current agricultural system. As a concept, it accounts for the systemic obstacles to the universal realization of the right to adequate food while also providing an alternative food system centred on the decisions of small-scale food producers. Contrary to capitalist and colonialist approaches to food production, food sovereignty is concerned with universal access to culturally appropriate nutritious foods produced through ecological means. Through a combination of normative and descriptive claims, this thesis examines the official recognition and realization of the
right to food sovereignty as a proxy of Marxist ideology. Food sovereignty empowers the rights-holder to ensure the continued realization of their right to adequate food in underscoring the fact that rights realization is not static in nature but, an ongoing endeavour. As such, the process called for to implement an alternative food system is one of decolonization.ThesisMaster of Arts (MA)Despite the existence of enough food for the sustenance of the global populace, there are obstacles prohibiting economic and physical access to food. These obstacles are created and maintained by the institutions and social structures that put forth policies encouraging economic and social inequality. The role which small-scale food producers play in global society is integral to the realization of the human right to adequate food. However, the current agricultural system de-values their work. Conceptually, food sovereignty highlights the oppressive nature of the agricultural system and puts forth a response that focuses on small-scale food producers assuming control over the food system. Commodification and exploitation are inherent characteristics of both the capitalist and colonial systems. Food sovereignty aims at dismantling oppressive systems through anti-capitalist and anti-colonial efforts sanctioned by the mobilization and collaboration of oppressed peoples within the context of food production
