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
A hierarchical and longitudinal analysis of the effects of international food and agricultural commodity price surges on domestic income distribution
No full textAn important question debated among development scholars and professionals is whether the distribution of income within nations is becoming less equitable due to the forces of globalization. This study investigated the effect of a single global economic event, the 2006 to 2008 global food price surges, on domestic income distribution in Argentina.
The specific purpose of this study was to examine the hypothesis that the surges in the 2006 to 2008 international food prices for corn (maize), rice, soybean, and wheat, impacted income distribution in Argentina. This study also explored the relationship between domestic food prices and income distribution while controlling for the effects of variables suggested by the sociological and economic theories of Modernization, Dependency, World-System, and Comparative Advantage. The theoretical measures were the concentration of land ownership, trade openness, foreign direct investment, gross domestic product (GDP), gross secondary school enrollment, life expectancy, and the poverty gap.
Previously collected, secondary data on the middle-income country, Argentina, between 2000 and 2009, were analyzed. Using quantitative research techniques data were accessed via four database web sites. Data were downloaded into, and analyzed with, the Statistical Package for the Social Sciences software (SPSS). This study collected data from the Socio-Economic Database for Latin America and the Caribbean (SEDLAC), the World Bank Development Indicators, The United Nations Educational, Scientific, and Cultural Organization (UNESCO) Institute for Statistics, and the Food and Agriculture Organization of the United Nations (FAO).
Findings indicated that the 2006 to 2008 food price surges significantly impacted the distribution of income in Argentina. The impacts of the food price surges were different among different income quintiles and the distribution of income to the top income quintile, Q5, increased. However, over the long-term, 2000 to 2009, improved life expectancy and a reduced national poverty gap influenced the effect of the price surges. Between 2000 and 2009 only the price of rice had a significant and negative impact on the top income quintile Q5, share of income, thus reducing income inequality. In summary, in Argentina, the 2006 to 2008 food price surges increased income inequality. However, the long-term impact of improved human development measures limited the negative effects of price surges in rice and contributed to decreased income inequality
Promoting farm to market diets: A study of Hispanic women’s health information seeking behaviors
No full textIn this paper, a model of health media usage is developed to understand how the target population that is Hispanic women makes decisions and the sources they turn to for information on health related matters. Key factors used in the investigation process were health behaviors, acculturation and socio-economic status indicators (SES). The objective of the project is to understand how Hispanic women acquire health knowledge. Understanding health media usage will enable us to recommend best education practices for the promotion of healthy lifestyles. A qualitative research design was used. Acculturation and health behaviors are direct influencers of health media usage. SES indicators such as age, income and education moderate the relationship between the independent and dependent variables. Future research should consider additional variables such as health concern and health motivation along with quantitative research to test the model
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
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
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
