Cana, café, cacau: agrarian structure and educational inequalities in Brazil
Full text linkThe present paper explores the relationship between agrarian structure and human capital formation between and within Brazil’s federal units. It is argued that whether states’ agriculture is in plantation style, based on
cheap coerced labor, or organized around family farming matters for the formulation of educational policies. According to the main claim, landlords were not interested in paying higher taxes to educate the masses and curtailed the expansion of schooling in order to keep a cheap workforce and maintain their monopoly over the decision-making process. Describing several episodes in Brazil’s history of public instruction, the paper stresses the distributional conflicts over education as well as the rural aristocracy’s resistance towards broadly-targeted, citizenship-enhancing educational policies. The descriptive evidence is complemented by statistical analyses employing historical as well as more recent data. It is shown that states characterized by a more egalitarian land distribution, which are not under the dominance of powerful landlords, exhibit better educational coverage and enhanced instruction quality. They also spend more on schooling.El presente artículo estudia la relación entre la estructura agraria y la formación de capital humano, tanto dentro como entre las unidades federales de Brasil. Se argumenta que la agricultura de los Estados es de estilo plantación — basado en mano de obra forzada barata, o por el contrario organizada alrededor de la granja familiar — es crucial para la formulación de las políticas educativas. De acuerdo a esta hipótesis, los propietarios de la tierra no estaban interesados en pagar impuestos más altos para educar a las masas y restringieron la expansión escolar con la intención de mantener una mano de obra barata y el monopolio del proceso de toma de decisiones. A través de la descripción de distintos episodios de la historia de la instrucción pública en Brasil, el artículo muestra los conflictos distributivos sobre la educación y la resistencia de la aristocracia rural en relación con los más amplios objetivos ciudadanos para intensificar las políticas educativas. La evidencia descriptiva se complementa con el análisis estadístico de datos históricos y recientes. Se muestra que los Estados con una distribución más igualitaria de la tierra, que no están bajo el dominio de poderosos propietarios de la tierra, tuvieron una mejor cobertura y calidad educativa. Asimismo, demostramos que invirtieron más en escolarización
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
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
Ethnic fractionalization, natural resources and armed conflict
Full text linkThus far, researchers working on ethnicity and resources as determinants of civil conflict have operated largely independently of each other. While there is plenty of evidence that natural resources may spur armed conflict, empirical evidence for the nexus between ethnic fractionalization and conflict remains inconclusive. Some authors conclude that ethnically fractionalized societies are actually spared from intrastate violence. Others find either a positive relationship or none at all between ethnic fragmentation and internal conflict. In this context, this paper serves two purposes: first, it shows that salience-based fractionalization indices are associated with a higher risk of ethnic conflict onset; second, it finds evidence that oil further increases the conflict potential within fractionalized countries. The combination of oil and a shared identity seems to help overcome the collective action problems associated with rebellion, by providing recruitment pools, strong motives and the necessary financial means for insurgency. Employing logit models for pooled time-series cross-sectional data, our quantitative analysis shows that various ethnic fractionalization indicators are robustly linked to a substantially increased risk of ethnic armed conflict onset in a subset of oil-abundant countries
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
