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
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
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

Development Transitions in Small-Scale Fisheries – Evaluating Socio-Ecological Impacts of Coastal Tourism Development in the Colombian Pacific
Get PDFTourism and small-scale fisheries are two of the most important economic sectors in coastal areas, yet the impact of tourism development on fisheries has been understudied within the SSF literature. Within fisheries, the prevailing narrative views tourism as a sustainable development option that will bring socio-economic benefits to the community and reduce pressure on the fishery. In reality, tourism development presents opportunities as well as significant risks to social and ecological dimensions of the fishery but these interactions and possible outcomes are not well documented in the literature. Proactive fisheries management that is designed to accompany and adapt to tourism development is the best way to maximize benefits and minimize risks. However, to anticipate and plan for impacts requires a better understanding of tourism fishery interactions. This dissertation research explores how tourism development impacts small-scale fisheries – first synthesizing the fragmented literature to develop a conceptual framework, then investigating these interactions through an empirical case study in coastal Colombia. The conceptual framework encompasses the range of potential fishery impacts and identifies the primary causal mechanisms that create them. Although outcomes vary, this variation is due to difference in contextual factors related to the characteristics of tourism development, sensitivity of the social-ecological system, and mediating or adaptive capacity of local governance. Therefore, the framework can be combined with local knowledge to support more robust site-specific assessments to inform strategic policy and management interventions. This framework increases the legibility of the fragmented literature but also highlights the need for more in-depth study of tourism impacts on fishing livelihoods and resource use. Within this exiting research, studies document various aspects of tourism-fishery interactions, but it is not clear how they combine to impact total fishing pressure. The addition of alternative livelihoods is widely expected to alleviate pressure on fisheries resources, yet rural development transitions often accelerate exploitation of natural resources. Through a comparative case study of fishing behavior and livelihood engagement in neighboring fishing communities in the Colombian Pacific, I analyze how tourism development impacts community-level fishing pressure, then compare these to tourism impacts on gleaning livelihoods. and consider the implications Findings indicate that while tourism development leads to a decline in fishery participation, this decline can be more than offset by increases in fishing effort and improvements in fishing methods. This is related to an overall pattern of livelihood specialization and intensification that results in a divergence of household-level fishing behavior — between those that exit the fishery and those that fish more intensively – and an increase in community-wide fishing pressure. However, impacts vary from place to place due to contextual factors in the biophysical environment and socio-political systems that shape how tourism development affects fishing behavior and whether or not it is likely to benefit sustainable small-scale fisheries.In contrast to fishing, tourism development is associated with a decline and disappearance of gleaning practices. This highlights important differences within the small-scale fishery sector related to labor practices, livelihood engagement, and the socio-economic role of gleaning and fishing. Collectively, these findings can be used to support place-based assessments in order to anticipate impacts, proactively design fisheries management, and inform more sustainable tourism development planning

The Political Economy of Climate Aid: Domestic Energy Interests and Domestic Institutions
Get PDFIn the face of the global climate crisis, wealthy states have pledged international aid to support mitigation and adaptation in developing countries. Existing studies of climate aid have three limitations. Results regarding donor preferences are inconsistent. Climate aid is viewed as the same as other types of foreign aid, and donors are treated as unitary actors, ignoring domestic interests and domestic institutions. As a result, existing research does not provide a comprehensive explanation for variation in state contributions to climate aid. This project seeks to unpack the black box of donor state preferences, examining the relative influence of the fossil fuel and renewable energy industries on donor states’ climate aid contributions as a proportion of total overseas development assistance. The research tests three sets of hypotheses: (1) The fossil fuel industry is likely to be influential when it is a major provider of the energy consumed in the state; (2) The renewable energy industry is likely to be influential when it has potential to be a major energy provider in the future; (3) The domestic institutional context in which these industries operate shapes the relative influence of both industries. The dissertation employs a cross-sectional time series analysis from 2002-2015 to investigate these relationships in 28 OECD donor states. The findings are that more renewable electricity production and more fossil fuel consumption within a state is correlated with higher amounts of climate aid provided by that state. In addition, when the renewable energy industry is growing at a faster rate than the fossil fuel industry, this is correlated with more climate aid provided by that state, specifically when that state has strong democratic institutions. The results expand our understanding of what shapes donors’ climate preferences and what additional barriers exist to climate aid
