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
Sectoral allocation by gender of Latin American workers over the liberalization period of the 1990s
Get PDFThe recent restructuring of Latin American economies has renewed interest in the effects of trade liberalization, on labor markets, and on the gender division of labor. The author does not attempt to establish casuality between economic reforms, and the types of jobs that men and women hold. Instead, she provides a detailed description of the trends in male, and female formal, and informal sector participation during the economic reform period in Argentina, Brazil, and Costa Rica. The author first compares the gender composition of the formal, informal wage, and self-employment sectors in a year before reforms (1988 for Argentina, 1989 for Brazil, and Costa Rica), and a year after reforms implementation (1997 for Argentina, 1995 for Brazil and Costa Rica). Although women continued to be more likely than men to work in the informal wage sector, there is no trend of"masculinization"or"feminization"of the informal sector, or any other. Instead, in Argentina men have overtaken women as the most prevalent workers in the informal wage sector, while in Brazil, the opposite has occurred (as men move into self-employment). In Costa Rica there have been no statistical, observable changes. The author then considers the distribution across sectors within each gender group, to identify whether men, and women are more likely to select different sectors in the post-reform period relative to the pre-reform period. Among both men, and women in all three countries (except Brazilian men), workers have become more likely to hold informal wage jobs, and less likely to hold formal sector jobs. Trends in human capital accumulation explain these changes for both men, and women, while changes in gender roles, primarily in homecare and marriage, do not seem to have an effect.Health Monitoring&Evaluation,Labor Policies,Population&Development,Public Health Promotion,Environmental Economics&Policies,Health Monitoring&Evaluation,Environmental Economics&Policies,Population&Development,Banks&Banking Reform,Work&Working Conditions
Towards a new industrial policy: The United States economic policy agenda post-COVID-19
Get PDFThis document examines the United States economic policy agenda proposed by President Joe Biden following his inauguration in January 2021, the discussions in the United States Congress since then, and the resulting legislations that have been signed into law. It also details government efforts to address supply chain bottlenecks and legislative efforts to pass a unified bill on increasing innovation and strengthening competitiveness. Four major legislations –the American Rescue Plan Act, the Infrastructure Investment and Jobs Act, the CHIPS and Science Act, and the Inflation Reduction Act– were signed into law as a result. The last three together suggest that the United States government appears to be moving towards a new industrial policy, focused on semiconductors and defense technology, and on clean energy.Abstract .-- Introduction .-- I.

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
La exportación de alimentos a Estados Unidos: principales desafíos para América Latina y el Caribe y guía de acceso a la información
Get PDFIncluye BibliografíaEl comercio internacional de productos alimentarios ha aumentado sensiblemente en las últimas décadas, entre otras razones, debido al crecimiento del consumo de alimentos per cápita a nivel mundial. Estados Unidos no ha sido la excepción. El crecimiento del consumo per cápita de alimentos en la economía más grande del mundo fue de aproximadamente 6 por ciento en los últimos 10 años. Al mismo tiempo, un porcentaje creciente del consumo de alimentos en Estados Unidos es abastecido del extranjero. En el año 2005, por cada cien dólares gastados en alimentos en Estados Unidos, trece eran de origen importado, 3.5 eran gastados enLatino América y el Caribe. Las cifras hablan del enorme potencial del mercado agroalimentario de los Estados Unidos para las exportaciones de la región. Sin embargo, anualmente miles de productos originarios de Latino América y el Caribe son rehusados la entrada a ese mercado por diversas razones. A la luz de los crecientes lazos comerciales entre la región y Estados Unidos y de la oportunidad potencial de los mismos al desarrollo económico de la región, varios gobiernos han planteado la necesidad de conocer el número de detenciones anuales en los puertos de entrada norteamericanos, cuales son los productos más afectados y las razones más frecuentes a los efectos de desarrollar las capacidades técnicas e institucionales necesarias para agilizar el movimiento de los bienes y servicios a través de la frontera con Estados Unidos. Con el objetivo de atender esta necesidad de asistencia técnica, la Oficina de la CEPAL en Washington ha elaborado una base de datos que documenta el número de detenciones por país y por producto y las razones de su detención para el período que va desde 2001 al 2005. La base de datos se actualizará anualmente.El objetivo de este documento es presentar la base de datos así como realizar un análisis de los productos más afectados a los efectos de orientar a los países exportadores en cuanto a los cambios necesarios para facilitar el acceso de dichos productos al mercado. El documento contiene además una guía de acceso a la información sobre los procesos, certificaciones, estándares y regulaciones que deben satisfacer los exportadores de la región a los efectos de acceder el mercado estadounidense para aquellos productos que muestran un mayor número de detenciones
