Liliana Maresca y el cuerpo disponible. Revisitando el erotismo, entre la alquimia y el ojo avizor

El artículo parte de la retrospectiva Liliana Maresca: el ojo avizor. Obras 1982-1994, curada por Javier Villa y realizada en el MAMBA entre agosto y noviembre de 2017. A partir de algunos recorridos ofrecidos en la muestra, se reflexiona sobre las acciones y obra de la artista argentina, que pueden ser pensadas desde las lecturas feministas y de las desobediencias sexuales, en particular el trabajo sobre el cuerpo propio, el erotismo y la sexualidad que Maresca lleva adelante en sus últimas acciones performáticas.Fil: Gutierrez, Maria Laura.

Occupational Physical Activity and Cardiovascular Risk Factors Profile in the Adult Population of the Southern Cone of Latin America: Results From the CESCAS I Study

OBJECTIVE: We explore the association between occupational physical activity (OPA) and cardiovascular risk factors in four cities of the Southern Cone. METHODS: Robust multivariable linear regression models were used to examine the associations. RESULTS: The working population was constituted by 1868 men and 1672 women. Men performing high levels of OPA showed higher levels of high-density lipoprotein (HDL; mean adj. diff. = 2.24 mg/dL; P = 0.004), lower levels of triglycerides (-24.59 mg/dL; P = 0.006), and total cholesterol (TC)/HDL ratio values (-0.21; P = 0.015) than reference. Women in the highest category of OPA had higher levels of HDL (2.85 mg/dL; P = 0.006), lower TC/HDL (0.27; P = 0.001), and low-density lipoprotein/HDL ratios (-0.18; P = 0.003) than sedentary activities. CONCLUSION: Individuals who performed high levels of OPA did not exhibit a worse cardiovascular risk profile and an improvement on selected biomarkers was observed when compared with those performing sedentary activities.Fil: Poggio, Rosana.

Effect of row orientation on soil water content and vine water status on a Cabernet franc vineyard in Madrid, spain

The aim of this study was to evaluate the effects of row orien¬tation on vine and soil water status in an irrigated vineyard. The trial was developed during 2006, 2007 and 2008, in the South East region of Madrid (Spain) on 5-year old Cabernet franc grapevines (Vitis vinifera L.) grafted onto 140Ru. Plant spacing was 2.5 m x 1.5 m and vines were trained to a VSP. Four orientations were stu¬died: North-South (N-S), East-West (E-W), Northeast-Southwest (N+45) and North-South +20o (N+20). Irrigation (0.4•ET0) started when shoot growth stopped. Soil water availability was measured using a TDR technique with forty buried probes. Row orientation did not have any effect on water consumption in the vineyard. At maturity, leaf water potential was measured at predawn, early mor¬ning, midday and 14:00 solar time, on both canopy sides - sun and shade – ; the early morning measurement was the one that better differentiated treatments. Leaf water potential was a good indica¬tor of plant water status. Differences between (N-S and E-W) and (N+20 and N+45) treatments were obtained both on sun and shade canopy sides, N+20 and N+45 having lower leaf water potentials then drier leaves. The water stress integral shows that N-S and E-W reach the end of maturation with a greater level of hydration than N+45 and N+20. As a whole, N+45 and N+20 orientations, without affecting too much the soil available water content, induce regularly more water stress to the vine at some periods, probably due to an higher sunlight interception in early morning which makes water limitation for the vine more early and thus more severe during the day

The effect of a transfer program for the elderly in Mexico City on co-residing children's school enrollment

This paper studies whether the increase in government transfers, induced by an old-age pension program for individuals age 70 and older in Mexico, affects co-residing children's school enrollment, using a regression discontinuity analysis. Results suggest that while household composition and other household-level characteristics do not change significantly at the cutoff age for program eligibility, co-residing children's school enrollment increases significantly. This suggests that public resources for older adults might generate benefits for other age groups. An additional finding is that the increase in school enrollment takes places mostly at the program eligibility cutoff and not before. Given that the program transfer is known and potentially anticipated by individuals who are only a few years away from being eligible, this suggests that households might have credit constraints

External Validation of Cardiovascular Risk Scores in the Southern Cone of Latin America: Which Predicts Better?

Introducción: La estimación inexacta del riesgo cardiovascular poblacional puede llevar a un manejo inadecuado de las intervenciones médicas preventivas, como, por ejemplo, el uso de estatinas. Objetivo: Evaluar la validez externa de ecuaciones de predicción de riesgo cardiovascular en población general del Cono Sur de Latinoamérica. Material y métodos: Se evaluaron ecuaciones que incluyen variables evaluadas en el estudio CESCAS y que predicen tanto morbilidad como mortalidad cardiovascular global (CUORE, Framingham, Globorisk y Pooled Cohort Studies Equations). Para cada ecuación se realizó un análisis independiente en el que se tuvieron en cuenta los eventos cardiovasculares relevados. Se evaluó la discriminación de cada ecuación a través del cálculo del estadístico-C y el índice Harrell C. Para evaluar la calibración se graficó la proporción de riesgos observados vs. estimados por quintilos de riesgo para cada ecuación y se calculó la pendiente β de regresión lineal para las estimaciones. Se calculó sensibilidad y especificidad para la detección de personas con elevado riesgo cardiovascular. Resultados: La mediana del tiempo de seguimiento de la cohorte al momento del análisis es de 2,2 años, con un rango intercuartilo de 1,9 a 2,8 años. Se incorporaron a los análisis 60 eventos cardiovasculares. Todos los valores de estadístico-C y del índice de Harrell fueron superiores a 0,7. El valor de la pendiente β más alejado de 1 fue el de Pooled Cohort Studies Euations. Conclusiones: Si bien los parámetros de validación externa evaluados fueron similares, CUORE, Globorisk y el índice de Framingham fueron las ecuaciones con mejores indicadores globales de predicción de riesgo cardiovascular.Background: Inaccurate estimates of demographic cardiovascular risk may lead to an inadequate management of preventive medical interventions such as the use of statins. Objectives: The aim of this study was to evaluate the external validity of cardiovascular risk equations in the general population of the Southern Cone of Latin America. Methods: Equations including variables evaluated in the CESCAS cohort study and that estimate overall cardiovascular mortality (CUORE, Framingham, Globorisk and Pooled Cohort Studies) were assessed. For each equation, an independent analysis was performed taking into account the cardiovascular events originally considered. Discrimination of each equation was evaluated through C-statistic and Harrell’s C-index. To assess calibration, a graph was built for each equation with the proportion of observed events vs. the proportion of estimated events by risk quintiles and the β slope of the resulting linear regression was calculated. Sensitivity and specificity were determined for the detection of people at high cardiovascular risk. Results: The median follow-up time of the cohort at the time of the analysis was 2.2 years, with an interquartile range of 1.9 to 2.8 years. Sixty cardiovascular events were incorporated into the analysis. All C-statistic and Harrell’s-C index values were greater than 0.7. The value of the β slope farthest from 1 was that of the Pooled Cohort Studies score. Conclusions: Although the external validation parameters evaluated were similar, CUORE, Globorisk and the Framingham equations showed the best global performance for cardiovascular risk estimation in our population.Fil: Gulayin, Pablo Elías.

Terrestrial invertebrate prey for juvenile chinook salmon: abundance and environmental controls in an Interior Alaska river

Thesis (M.S.) University of Alaska Fairbanks, 2011Terrestrial prey subsidies can be a key food source for stream fish, but their importance and environmental controls on their abundance have not been widely documented in high latitude ecosystems. This study investigated terrestrial invertebrate prey availability and predation by age-0+ juvenile chinook salmon (Oncorhynchus tshawytscha), overlap between terrestrial infall and drift to diet, and the relationship between diet to stream temperature and discharge in the Chena River, Interior Alaska. Terrestrial infall, drift, and juvenile chinook diet varied widely through the summers (May-September) of 2008 and 2009. Drift was comprised of 33% terrestrial and 67% aquatic invertebrate mass, while juvenile chinook diet contained 19% terrestrial, 80% aquatic, and 1% unidentifiable invertebrate mass. The proportion of terrestrial invertebrate mass consumed increased through summer and, at times, made up to 39% of total diet. Low similarity of invertebrates in diet and infall, and diet and drift suggested that fish were, in part, prey-selective, selecting hymenopterans and chironomid midges (Diptera). In both years, prey mass consumed and discharge varied inversely, but no correlation was found between proportion of terrestrial invertebrates consumed and discharge. However, the two sampling dates with the highest proportion of terrestrial invertebrates consumed occurred shortly after a 60-year flood, indicating that terrestrial invertebrates may be important during rain and associated high water. This study found that, although terrestrial infall and drift are highly variable, terrestrial invertebrates are an important prey resource for rearing chinook salmon in this high latitude riverine system, especially later in the summer.Arctic-Yukon-Kuskokwim Sustainable Salmon Initiative, Alaska Department of Fish and Gam
