The effects of river discharge and seasonal winds on the shelf off southeastern South America

The Rio de la Plata waters form a low salinity tongue that affects the circulation, stratification and the distributions of nutrients and biological species over a wide extent of the adjacent continental shelf. The plume of coastal waters presents a seasonal meridional displacement reaching lower latitudes (28,S) during austral winter and 32 degrees S during summer. Historical data suggests that the wind causes the alongshore shift, with southwesterly (SW) winds forcing the plume to lower latitudes in winter while summer dominant northeasterly (NE) winds force its southward retreat. To establish the connection between wind and outflow variations on the distribution of the coastal waters, we conducted two quasi-synoptic surveys in the region of Plata influence on the continental shelf and slope of southeastern South America, between Mar del Plata, Argentina and the northern coast of Santa Catarina, Brazil. We observed that: (A) SW winds dominating in winter force the northward spreading of the plume to low latitudes even during low river discharge periods; (B) NE winds displace the plume southward and spread the low salinity waters offshore over the entire width of the continental shelf east of the Plata estuary. The southward retreat of the plume in summer leads to a volume decrease of low salinity waters over the shelf. This volume is compensated by an increase of Tropical waters, which dominate the northern shelf. The subsurface transition between Subantarctic and Subtropical Shelf Waters, the Subtropical Shelf Front, and the subsurface water mass distribution, however, present minor seasonal variations. Along shore winds also influence the dynamics and water mass variations along the continental shelf area. In areas under the influence of river discharge, Subtropical Shelf Waters are kept away from the coastal region. When low salinity waters retreat southward, NE winds induce a coastal upwelling system near Santa Marta Cape. In summer, solar radiation promotes the establishment of a strong thermocline that increases buoyancy and further enhances the offshore displacement of low salinity waters under the action of NE winds.

Potential of a neutrino detector in the ANDES underground laboratory for geophysics and astrophysics of neutrinos

The construction of the Agua Negra tunnels that will link Argentina and Chile under the Andes, the world's longest mountain range, opens the possibility of building the first deep underground laboratory in the Southern Hemisphere. This laboratory has the acronym ANDES (Agua Negra Deep Experiment Site) and its overburden could be as large as similar to 1.7 km of rock, or 4500 mwe, providing an excellent low background environment to study physics of rare events like the ones induced by neutrinos and/or dark matter. In this paper we investigate the physics potential of a few kiloton size liquid scintillator detector, which could be constructed in the ANDES laboratory as one of its possible scientific programs. In particular, we evaluate the impact of such a detector for the studies of geoneutrinos and Galactic supernova neutrinos, assuming a fiducial volume of 3 kilotons as a reference size. We emphasize the complementary roles of such a detector to the ones of the Northern Hemisphere neutrino facilities, given the advantages of its geographical location.

Comparative Study of Informal Health Care Networks and Elderly Health Status in Argentina and Cuba

The objective of this study is to evaluate the impact of informal care support networks on the health status, life satisfaction, happiness and anxiety of elderly individuals in Argentina and Cuba. Recent economic changes, demographic changes, the structure of families and changes in women?s labor participation have affected the availability of informal care. Additionally, the growing number of elderly as a percentage of total population has significant implications for both formal and informal care in Argentina and Cuba. Methods: The SABE - Survey on Health, Well-Being, and Aging in Latin America and the Caribbean, 2000 was used as the data source. The survey has a sample of 10,656 individuals aged 60 years and older residing in private households occupied by permanent dwellers in 7 cities in the Latin American and Caribbean region. My study will focus on the Buenos Aires and Havana samples in which there were 1043 individuals and 1905 individuals respectively. General sampling design was used to establish comparability between countries. Individuals requiring assistance are surveyed on their source of help and the relative impact of informal versus paid help is measured for this group. Other measures of social support (number of living children, companionship and number of individuals living in the same dwelling) are used to measure networks for the full sample. Multivariate probit regression analyses were run separately for Cuba and for Argentina to evaluate the marginal impacts of the types of social support on health status, life satisfaction, happiness and anxiety. Results: For Argentina, almost all of the family help variables positively impact good health. Getting help from most other members of the family negatively impacts satisfaction with life. Happiness is affected differently by each of the family help variables but community support increases the likelihood of being happy. Although none of the family or community help variables show statistical significance, most negatively affect anxiety levels. In Cuba, all of the social support variables have a positive marginal impact on the health status of the elderly. In this case, some of the family and community help variables have a negative marginal impact on life satisfaction; however, it appears that having those closest to the elderly, children, spouse, or other family, positively impacts life satisfaction. Most of the support variables negatively impact happiness. Receiving help from a child, spouse or parent is associated with a marginal increase in anxiety, whereas receiving help from a grandchild, another family member or a friend actually reduces anxiety. Discussion: The study highlights the necessity for enhancing the coordination of various care networks in order to provide adequate care and reduce the burdens of old age on the individual, family and society and the need for consistent support for the caregivers. More qualitative work should be done to identify how support is given and what comprises the support. The constant change and advancement of the world, and the growth of the Latin American and Caribbean region, suggests that more updates studies need to be done.

COMPARATIVE STUDY OF INFORMAL HEALTH CARE NETWORKS AND ELDERLY HEALTH STATUS IN ARGENTINA AND CUBA

This study will explore familial and friend support networks and living arrangements among elderly individuals in Latin America and the impact that this type of support has on the health of the elderly individuals in the countries of interest. Using data from the Survey on Health and Well-Being of Elders (SABE) from 1999-2000, I will explore which type of support has a larger impact on overall health. I will also measure differences in unmet needs for certain health services. This topic is particularly interesting because it will help to uncover what policies are best for aiding in the healthcare of the elderly in aging population. Lastly, the investigation of this topic will allow me to draw conclusions about the most effective means of social and public policy for the elderly community and provide me with information about the role of both informal provisions of support from family and friends, and formal provisions of support from the government. My primary focus will be on Argentina, using Buenos Aires as the sample city, and Cuba, using Havana as the sample city. These two countries have increasingly aging populations, poorer resources and vast inequalities, but, extremely different political, economic and cultural situations. Comparing the two countries will further allow me to determine correlations between health and the existence of support networks, as well as provide me with information to make more general claims that may be of use in the United States. Argentina is particularly interesting to me because of my abroad experience and homestay experience with an older Argentine woman who lived alone but depended upon her family for many healthcare needs, doctors’ visits and general well-being. In Argentina, I experienced a different form of living than I am used to in the United States, where many older individuals or couples live in nursing homes or assisted living facilities rather than alone or with family. The changing economic climate of the two countries coupled with labor patterns of women returning to work at rapid rates indicates that policies cannot just rely on either the formal or informal sector but require a combination of the two sectors working together.This paper will first give background on the difference in the economies and the health care systems in Argentina and Cuba and will show why it interesting to study and compare these two countries. I will then discuss the health status of the elderly in each population as well as discuss the informal care networks and the role of family in each country. This section will then be followed by a description of the data and methods used. I will end by drawing conclusions about the study and the outcomes, and then I will attempt to make suggestions about effective health care policies for the elderly.

Campaña por la despenalización del aborto terapéutico en Chile

Fortaleciendo espacios de debate e incidencia para favorecer el acceso al aborto legal en Santiago del Estero, Argentina

Ante los serios obstáculos que enfrentan las mujeres para acceder al aborto legal y seguro en la provincia de Santiago del Estero, la ADC se propuso, a través de actividades de capacitación e incidencia, entablar un diálogo con las autoridades públicas de la provincia y apoyar a la sociedad civil a fin de enfrentar dichos obstáculos. Las acciones de ADC apuntaron a construir capacidad jurídico-técnica a ONGs, grupos de mujeres, abogad@s, prestadores de salud y a fomentar un debate abierto con participación de funcionarios públicos y representantes de la sociedad civil respecto de las implicancias del fallo “F.,A.L.” dictado por la Corte Suprema de Justicia de la Nación (CSJN) en marzo de 2012. El objetivo general del proyecto radicó en proveer a estos actores de nuevas herramientas que les permitan garantizar las vías de acceso apropiadas para el acceso al aborto legal y seguro especialmente de mujeres en situación de vulnerabilidad

Memoria del fuego : Otros lugares

¿Cómo funciona la memoria? Dos originales formas de abordar la cuestión: Pierre Nora y Les lieux de la mémoire, que vieron la luz a partir del bicentenario de la Revolución Francesa; y Memoria del fuego, esa ?especie de Biblia? latinoamericana que trae Eduardo Galeano de su regreso del exilio en 1984. ¿Cómo estos dos frescos construyen la historia de las sociedades de las cuales surgen?

Valorización de la naturaleza y disputa por el territorio en la Provincia de Santa Cruz

Desde los inicios de la colonización europea, la historia de la Patagonia es la trayectoria de la ocupación para la puesta en valor de la riqueza de sus bienes naturales en el suelo, subsuelo y en su extenso litoral marítimo. Asentados primero en la explotación del ovino, luego del petróleo, el gas y el carbón y recientemente de la pesca, la minería metalífera y el turismo internacional, los territorios de las actuales provincias de Santa Cruz, del Chubut y de Tierra del Fuego, al igual que sus pares trasandinos de las regiones de Aysén y Magallanes, son espacios ricos en recursos. Para la puesta en valor de los territorios por parte del capital, hacen falta dos condiciones básicas: la existencia de bienes naturales y la presencia de fuerza de trabajo, las cuales, dependiendo de la actividad, pueden o no estar presentes. En algunos casos, se hace necesario adecuar estos espacios mediante equipamientos e infraestructuras, la atracción de trabajadores de diversa calificación y la presencia estatal, en un doble proceso de expansión geográfica y acumulación por desposesión que asegure la valorización en general. En estos territorios, periféricos desde el punto de vista espacial, cada proceso de valorización particular exigió una combinación de apropiación, habilitación y organización del territorio específicas. En el presente artículo se apunta, en primer lugar, a presentar sintéticamente los procesos históricos de valorización de la naturaleza de la región, para luego analizar la actual situación del proceso en el territorio y los conflictos resultantes. En una segunda parte, teniendo en cuenta las tendencias mundiales de alta demanda de bienes naturales, se expondrán los escenarios futuros más probables en caso de acentuarse el actual modelo extractivo y rentista

Estudio de la logística en el eslabón final de la cadena de valor agroindustrial en la provincia de San Luis

La cadena de valor de los productos oleaginosos de la Provincia de San Luis cuenta en la actualidad con tres ventajas principales. La primera de ellas es que la provincia se encuentra estratégicamente ubicada en un corredor bioceánico de la República Agentina; la segunda es la implantación de la Zona de Actividades Logísticas (ZAL) en Villa Mercedes; y la tercera es el desarrollo empresarial motivado por las inversiones de empresas multinacionales en el sector. Para el intercambio comercial de países del Atlántico, como la Argentina, con los de Asia y Costa Oeste de los Estados Unidos es necesaria la integración entre la Argentina y Chile fortaleciendo lazos comerciales, culturales y sociales. La implantación de la Zona de Actividades Logísticas adquiere relevancia teniendo en cuenta que el principal efecto de este emprendimiento es la reducción sustancial de los costos operativos. Por otro lado, la fusión de empresas multinacionales con empresas del medio en industrias agroalimentarias provocará un aumento de la capacidad de procesamiento de granos (en particular maíz) en un 50, con lo que se estaría en condiciones de absorber más de la mitad de la cosecha de la provincia. Para los agricultores será un gran desafío aumentar la superficie cultivada para comercializar con un comprador local y ampliar el margen de rentabilidad al eliminarse los elevados costos por flete. El objetivo de este trabajo es analizar e interrelacionar los factores, los actores y el impacto de estas tres ventajas en el final de la cadena de valor de productos oleaginosos en la Provincia de San Luis
