Lidiando con las estadísticas internacionales en las ciencias sociales

Thus, the aim is pointed at the ability to make more precise comparisons. To do so, this work is divided into four parts: la definition of concepts of the social sciences, the description of the variables, the treatment of these and of quantitative data, and finally the scan on the main differences found in international statistics.Este artículo busca señalar algunos inconvenientes que surgen a partir de un extenso trabajo de comparación de la medición de variables en los distintos países, en el que se resaltan diferencias visibles.

Lidiando con las estadísticas internacionales en las ciencias sociales

Resumen: Este artículo busca señalar algunos inconvenientes que surgen a partir de un extenso trabajo de comparación de la medición de variables en los distintos países, en el que se resaltan diferencias visibles. Frente a esto, se busca aclararlas con el fin de poder realizar comparaciones más acertadas. Para eso, el trabajo se divide en cuatro partes: la definición de los conceptos en las ciencias sociales, la descripción de las variables, el tratamiento de ellas y de datos cuantitativos, y por último el repaso por las diferencias en las estadísticas internacionales.Abstract: This article tries to convey some inconveniences that result after an extensive work which compares the ways in which the variables of different countries are measured, due to the fact that there are visible differences amongst them.

Forecasting inflation in Argentina: A comparison of different models

In general, central banks are concerned with keeping the inflation rate stable while also sustaining output close to an efficient level. Under "inflation targeting", forecasts of the evolution of the general price level are an essential input for policy decisions and these are usually released in quarterly "Inflation Reports". The costs and benefits of transparency in monetary policy are widely debated, but the need for a central bank to incorporate forecasts of future inflation is broadly agreed. In short, forecasting inflation is of foremost importance to households, businesses, and policymakers. In 2016, the Central Bank of Argentina began announcing and inflation targeting scheme. In this context, providing the authorities with good estimates of relevant macroeconomic variables turns out to be crucial to make the pertinent corrections to reach the desired policy goals. This paper develops a group of models to forecast inflation in Argentina and conducts a comparison of their predictive ability at different horizons. Our variety of models includes: (i) univariate time series models, (ii) VARs, Bayesian VARs and Time-Varying Parameter VARs, and (iii) conventional New Keynesian Phillips Curves including one that incorporates money to evaluate its information content as a predictor of inflation. We compare the predictive performance of the different methods using the Giacomini-White test over the relevant horizons for monetary policy decisions

Effect of botanical and physicochemical composition of Argentinean honeys on the inhibitory action against food pathogens

Honey is a natural food with functional properties such as antioxidant and antimicrobial activities. These properties vary greatly depending on floral source, climate, and environmental and processing conditions. In this work, we characterized honeys on the basis of their botanical composition and clustered them according to their physicochemical parameters in order to find similarities, and assess their antibacterial action against microorganisms isolated from contaminated food. All honeys studied complied with international quality standards. The data showed differences between multifloral and unifloral honeys in their physicochemical parameters, as well as a direct correlation between colour, phenolic compounds, and antioxidant activity. -Antimicrobial activity resulted from hydrogen peroxide effect. Multifloral honeys with similar phenolic compounds and a botanical composition of eucalyptus and blueweed had greater inhibitory power against E. coli, P. aeruginosa, Salmonella spp., S. aureus and B. cereus.EEA FamailláFil: Ramos, Ornella Yolanda.

Estudio transversal clínico y epidemiológico de la enfermedad de Chagas en una área rural del Nordeste Argentino Clinical and epidemiological transversal study on Chagas' disease in a rural area of the Argentinian Northeastern

Esta investigación tiene por objeto analizar las características epidemiológicas, clínicas, electrocardiográficas y radiológicas de una población de seropositivos y seronegativos al Trypanosoma cruzi en una área rural del Departamento San Miguel, provincia de Corrientes, Argentina. Se seleccionaron 132 pobladores (58 hombres y 74 mujeres) de todos los grupos etareos para la realización de un examen clínico y cardiovascular. Se registraron síntomas y signos compatibles con afección cardíaca, tensión arterial, electrocardiograma de 12 derivaciones y radiografía anteroposterior de tórax. En la signo-sintomatología, anomalías electrocardiográficas y en las alteraciones radiográficas detectadas, no se observaron diferencias estadísticamente significativas entre seropositivos y seronegativos. Se concluye que si bien en la población objeto de estudio la infección chagásica no se asoció a mayor prevalencia de cardiopatía, cabe destacar que los pacientes chagásicos pertenecían a un grupo etareo muy joven con un 54,0% de ellos menores de 20 años y que el 45,0% de los pacientes mayores de 41 años tenían alteraciones electrocardiográficas.<br>The main goal was to know the epidemiologic, clinical, electrocardiographic and radiologic characteristics among a population of seropositives and seronegatives to Trypanosoma cruzi in a rural area of the Departament of San Miguel, province of Corrientes, Argentina. One hundred and thirty-two patients of different ages: 2-79 years old were researched (58 males, 74 females). In order to make a thorough assessment clinical evaluation and cardiologic testing were carried out. Signs and symptoms consistent with heart disease, blood pressure, 12-lead ECG registry and chest x-ray (PA view) were registered. In signs and symptoms, abnormal ECG patterns and radiologic abnormalities, non-significant statistic difference were observed. Although we were unable to find a significant relationship between chagasic infection and a higher prevalence for heart disease, it is important to stress the fact that 54.0% of the studied population was largely composed of very young patients whose ages were less than 20 years old, and 45.0% of those older than 41 years showed ECG abnormalities
