Sobre el sentido de lo social: asociacionismo y sociabilidad. Un breve balance
Partiendo del supuesto: las categorías sociabilidad y asociacionismo han adquirido un frecuente empleo dentro del campo de la investigación histórica, el presente artículo, lejos de exponer una investigación empírica y concreta, se detiene a reflexionar sobre los usos y abusos que se han realizado acerca de la temática. La intención es fijar líneas metodológicas, delimitar el concepto y reconocer los presupuestos teóricos que se juegan en la trastienda de estos. Para ello, en un principio revisaremos los usos más frecuentes del término para luego inmiscuirnos en la vertiente teórica central que articuló al campo historiográfico con la problemática de la sociabilidad: la teoría de Maurice Agulhon.Fil: Caldo, Paula.

Grados de pobreza e indigencia: aplicación a un caso
Mediante la aplicación de metodologías apropiadas para su cuantificación, las políticas que se ocupan de reducirla pueden ser revaloradas socialmente y planteadas en mejores términos. Se presenta un modelo alternativo para el método indirecto, el mismo utiliza metodología borrosa con el fin de establecer umbrales de pobreza en vez de que una frontera definida. El modelo propuesto se utiliza para la clasificación de diferentes familias rurales de la provincia de Misiones.Fil: Fernandez, María José. Universidad de Buenos Aires.

La revista como colección: Imágenes, arte y cultura en una revista cultural ilustrada
El fenómeno del surgimiento de las revistas recorre las últimas décadas del siglo XIX, pero aquiere una marcada influencia en el mundo editorial latinoamericano y fundamentalmente argentino a partir de la primera postguerra. Revistas de corte intelectual, artístico, político y en especial las ilustradas disputaron el espacio editorial a libros y folletines. Su forma de lectura, fragmentaria y plástica, permitía que accedieran a ellas un público más heterogéneo, que no sólo aspiraba recorrer sus páginas alrededor de un único tema o argumento, sino que además buscaba diversos tópicos de interés, acompañados por imágenes, y avisos publicitarios. Esta cualidad de las revistas se agudizó aún más en el segmento de las revistas ilustradas. En los albores de la década de 1920 tales publicaciones no olvidaron los complejos mecanismos de diseño y composición para seducir tanto a públicos de elite como populares. Dentro de este sector de noveles y frágiles revistas creadas en la entreguerra argentina, merece nuestra atención la revista “El Círculo” surgida en el seno de una asociación cultural del mismo nombre inaugurada en Rosario en 1912 . Este capítulo se aboca de lleno a su análisis resaltando su condición de revista ilustrada pero a su vez muestrario de un ideario coleccionista que marcó la época estudiada.Fil: Fernandez, Sandra Rita.

Towards data-congruent models of the term structure of interest rates
Bond yields can be decomposed into two unobservable components: the expected sequence of short-term rates and term premia. The identification of these two components is crucial to understand bond pricing and the effect of monetary policy on the term structure of interest rates. This paper illustrates how M.H. Pesaran's prescription of congruency between the data and the reduced form, explicitly derived from stochastic dynamic optimization, effectively facilitates the relevant decomposition. By examining the historical evolution of term structure models, we demonstrate that the chosen specifications have not consistently aligned with the data, presenting a missed opportunity. In fact, a data-congruent specification helps in improving forecasts of the dynamics of US short-term rates and generates stationary dynamics for the term premia
Approximating Whiteness: Race, Class, and Empire in the Making of Modern Elite/White Subjects
Gaztambide-Fernandez R, Angod LN. Approximating Whiteness: Race, Class, and Empire in the Making of Modern Elite/White Subjects. EDUCATIONAL THEORY. 2019;69(6):719-743.This essay takes up the messy relationship between whiteness and eliteness at the site of elite schools under conditions of global racial capitalism and empire. Ruben Gaztambide-Fernandez and Leila Angod theorize this relationship by describing the slippery ways in which whiteness and eliteness co-constitute each other and by tracing how the relationship between eliteness and whiteness is both historical and spatial. They argue that, in the twenty-first century, the entanglement between eliteness and whiteness produces a particular affective configuration and that elite schooling has become the key mechanism for producing what they call the elite/white subject. Gaztambide-Fernandez and Angod trace the making of the elite/white subject through three processes: the unhinging from time/history; the unhinging from space/land; and the obfuscation of whiteness/eliteness through the production of a particular cosmopolitan affect. They do this by looking specifically at how non-White subjects are invited into eliteness, always in a paradoxically precarious approximation in which whiteness, and therefore eliteness, can always be revoked. The ongoing collusion between the particular spatial and historical dimensions of the production of eliteness obfuscates the ways in which becoming elite always requires an approximation to whiteness and how both whiteness and eliteness must be constantly produced and secured
Quarry limestone dust as fine aggregate for concrete
In quarrying activities, rock is extracted and transformed into aggregate of various sizes for civil engineering applications. In this process waste fine aggregates (dust waste) are generated. The disposal of this type of waste is a further cost in the extraction process, but also a possible cause of environmental pollution (e.g. leaching into water reserves, atmospheric pollution as a result of small particles causing respiratory diseases or deposited on plants disrupting photosynthesis, affecting aquatic habitats, etc.). A strategy for the effective recycling of quarry dust does not only reduce waste generation and disposal, but also addresses protection of the environment. The Italian quarrying industry covers a relevant portion of global mineral extraction resulting in a significant production of fine waste. In some cases quarries are located close to ecological sensitive and protected areas and to the coast with higher risks for biodiversity (an example is the limestone extraction industry in Trapani, Sicily). In this context, the paper reviews the strategies proposed in the use of limestone fine waste, especially for concrete, and discusses an experimental program intended to assess the mechanical properties of concrete made with the fine limestone waste produced in the area of Trapani, as a partial substitute of fine aggregate (sand)
Costs and benefits of debt and debt service reduction
The author evaluates the costs and benefits of debt and debt service reduction (DDSR) from the point of view of five countries that have concluded Brady deals: Costa Rica, Mexico, the Philippines, Uruguay, and Venezuela. He concludes that, contrary to widely held views, commercial banks have probably benefited from the operations. Commercial bank participation in DDSR is voluntary, so direct financial savings to the country are probably negative at present values. The benefit from DDSR is not that debt is bought at"bargain prices"at the expense of commercial banks. It appears difficult to justify a DDSR operation on purely financial grounds. A more realistic way to look at a DDSR operation is to view it as a"project"that involves a certain financial cost. The return on such a project is how the DDSR operation improves the macroeconomy, or contributes to development. The main purpose of DDSR is to establish a more efficient arrangement between debtor countries and commercial banks, leading to improved conditions for development. A DDSR operation that does not help development is costly and should not be undertaken. The impact of DDSR on development is usually measured by the increase in the growth rate of GDP, but it is too soon to measure that for these five countries. A suitable alternative is to look at the change in investment patterns. A strong policy framework is needed if debt and debt service reduction are to significantly improve development. In Mexico and, to a lesser extent, Venezuela, improved and sustained strong adjustment policies have generated the greatest development benefits. Gains have been less in smaller countries where policies were not as supportive. The author concludes that for a country to benefit from DDSR, it needs significant indirect benefits (such as increased domestic and foreign savings). Direct benefits are likely to be negative because of the commercial banks'financial gains and because DDSR operations are frontloaded. DDSR operations cannot be justified solely by direct benefits and savings in cash flow.Strategic Debt Management,Banks&Banking Reform,Economic Theory&Research,Environmental Economics&Policies,Financial Intermediation
