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
Migration and coastal resource use in Papua New Guinea
No full textHuman migration is a considerable issue for many coastal societies, affecting the ways that people use and manage natural resources. This paper examines reasons for migration in 14 coastal communities in Papua New Guinea (PNG) and compares coastal resource use and socioeconomic conditions between migrants and non-migrants to test the hypothesis that migrants have different levels of coastal resource use than non-migrants. Migrants had lower participation in the fishery, ranked fishing as a less important livelihood strategy, and had lower involvement in village decision-making, but had higher levels of human development. Common property systems such as tenure rights may prevent migrants from accessing marine resources. However, migrants’ marginalization in decision-making processes may
become increasingly contested where resources are scarce and migrants desire an increasing say in how they are allocated. The current limited use of coastal resources by migrants may be a latent problem that needs to be considered by resource managers, particularly in areas where rapid socioeconomic change is occurring and tenure institutions are fragile
Poverty and the use of destructive fishing gear near east African marine protected areas
No full textPoverty may be an important influence on the exploitation of marine resources in tropical developing countries. A number of studies have hypothesized that destructive fishing gears, which can degrade habitat, capture high proportions of juvenile fish and ultimately lead to reduced yields, are primarily used by the poorer segments of society. However, few studies have empirically tested this relationship. This paper examines relationships between the use of destructive seine nets and thirteen socioeconomic conditions in communities adjacent to three peri-urban marine protected areas in east Africa. Fishers using destructive gears were younger, less likely to have capital invested in the fishery, had lower fortnightly expenditures and were poorer in two multivariate indices of material style of life. Based on the two multivariate material style of life indices, a binary logistic regression model classified whether fishers used destructive gears with almost 70% accuracy. These findings are broadly consistent with the literature on poverty traps, which are situations in which the poor are unable to mobilize the resources required to overcome low-income situations and consequently engage in behaviour that may reinforce their own poverty. Managers aiming to reduce destructive gear use may need to partner with civil society and donors to help break poverty traps
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
