On Income Distribution Dynamics in Argentina During the 1976–1983 Dictatorship: A Classical-Structuralist Interpretation
No full textThe long-lasting, distributive changes in Argentina during the 1970s have been extensively studied from different theoretical perspectives. What has not yet been sufficiently examined, however, are the reasons behind the non-monotonic trends observed on income distribution during this period and, in particular, under the dictatorial regime (1976–83). To fill this gap, we have developed a model inspired in the modern Classical-Structuralist approach to income distribution. We argue that the irregular trend of the real wage reveals that only a partial correspondence exists between the class interests of the 1976 coup and the effects on income distribution of the successive economic programs implemented by the dictatorship
Optimización aplicada a la programación de transporte ferroviario de pasajeros
No full textSe abordan los fundamentos del problema que enfrentan los operarios de una red ferroviaria para asignación de un cronograma óptimo de partidas y llegadas, de forma tal de resolver los conflictos que se suscitan cuando dos o más trenes se disponen a utilizar simultáneamente la misma parte de la red ferroviaria, considerando la demanda, los niveles de seguridad y los efectos de dicho resultado sobre la administración de la totalidad de la red. Así, se procederá a la especificación de las variables, restricciones y objetivos que entran en la consideración en lo que constituye el Problema de Programación de Eventos Periódicos (PESP, por sus siglas en inglés). Sobre la base de la experiencia europea, se intenta ofrecer una aproximación a los aportes de dicha metodología al sistema ferroviario de pasajeros, con miras a identificar conclusiones susceptibles de ser incorporadas en la regulación y administración del sistema ferroviario de pasajeros en el AMBA (Área Metropolitana de Buenos Aires)Fil: Alvarez, Ramiro Eugenio.

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
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
An Alternative View on Inflation in Argentina in the New Millennium: The Challenges of the Current Situation
No full textFil: Alvarez, Ramiro. Universidad Nacional de Moreno. Centro de Estudios de Economía Política y Desarrollo. Buenos Aires; ArgentinaFil: Medici, Florencia. Universidad Nacional de Río Negro. Instituto de Estudios en Ciencia, Tecnología, Cultura y Desarrollo. Río Negro; Argentina.This article interprets Argentina’s recent inflation process following the Classical-Structuralist approach. In this theoretical framework, the price dynamic is understood as the result of conflict between wage increases and devaluations in a price-taker economy open to trade and financial flows.
We argue that inflationary processes in Argentina during the new century, especially in the last decade, can be explained by devaluations triggered by dynamics linked to the external sector, resulting from financial deregulation processes and inflows of external liabilities. In this scenario, conflict inflation manifests through a persistent exchange rate-wage spiral.
Thus, national currency devaluations raise profit margins and price levels in a society with strong labor unions, which react by claiming wage increases. High inflation regimes lead to changes in income distribution that are incompatible with habits, history, and labor institutions, resulting in intense distributive conflict under “pendulum” governments that reflect a situation of political stalemate. Moreover, the State’s capability to implement anti-inflationary policies based on an exchange rate anchor depends on the amount of the monetary authority’s foreign currency reserves. The ability to intervene in the foreign exchange market aims to deal with conflicting social groups and external pressures pushing to generate devaluation.trueEste artículo interpreta el proceso inflacionario reciente de la Argentina siguiendo el enfoque Clásico-Estructuralista. En este marco teórico, la dinámica de precios se entiende como el resultado del conflicto entre aumentos salariales y devaluaciones en una economía tomadora de precios, abierta al comercio y a los flujos financieros.
Sostenemos que los procesos inflacionarios en Argentina durante el nuevo siglo, especialmente en la última década, pueden explicarse por devaluaciones desencadenadas por dinámicas vinculadas al sector externo, resultantes de procesos de desregulación financiera y del ingreso de pasivos externos. En este escenario, la inflación de conflicto se manifiesta a través de una persistente espiral tipo “salarios-tipo de cambio”.
Así, las devaluaciones de la moneda nacional elevan los márgenes de ganancia y los niveles de precios en una sociedad con sindicatos fuertes, que reaccionan reclamando aumentos salariales. Los regímenes de alta inflación conducen a cambios en la distribución del ingreso incompatibles con los hábitos, la historia y las instituciones laborales, generando un conflicto distributivo intenso bajo gobiernos “péndulo” que reflejan una situación de estancamiento político. Además, la capacidad del Estado para aplicar políticas antiinflacionarias basadas en un ancla cambiaria depende del monto de reservas en moneda extranjera de la autoridad monetaria. La capacidad de intervenir en el mercado cambiario apunta a enfrentar tanto a los grupos sociales en conflicto como a las presiones externas que empujan hacia la generación de una devaluación
