Background. The elderly population aged 60 and above is increasing rapidly throughout the world. The aging process affects physical health of individuals, which in turn affects sexuality and sexual activity. However, many elderly adults continue to engage in one or more forms of sexual activities well into their 70s, 80s, and even in 90s. Despite the widespread stereotypes, misconceptions, and negative attitudes surrounding sexuality in elderly adults, it has been found to be an important aspect of the health of the elderly. However, association between the frequency of sexual activity and mental well being among older adults has not been documented in the literature. ^ Methods. To test the hypotheses that mental well being indicators such as depression, anxiety, and stress were inversely associated with greater frequency of sexual intimacy, a secondary data analysis was conducted using the National Social Life Health and Aging Project (NSHAP) using multivariate logistic regression. The NSHAP was a population-based study that was conducted on a national scale including 1455 men and 1550 women aged 57-85.^ Results. Approximately 1430 (54.1%) of the total population reported being sexually intimate in the past 12 months whereas 1481 (45.9%) participants reported that they did not perform any sexual activity in the past 12 months. In addition, approximately 895(31.1%) participants reported engaging in sexual activity ≥ 2-3 times per month with 665 (78.9%) of these participants reported performing vaginal intercourse only, 14(2.0%) oral sex only, and 89(10.5%) reported performing both vaginal intercourse and oral sex. Controlling for socio-demographic characteristics, frequently (≥2-3 times per month) sexually active participants showed lower odds ratio of depression (OR= 0.60; 95%CI = 0.46, 0.78), anxiety (OR= 0.67; 95% CI= 0.53, 0.86), and stress (OR=0.73; 95% CI = 0.6, 0.88) compared to those who had less frequent sexual activity or who had no sexual activity in the past 12 months.^ Conclusion. Lower levels of depression, anxiety, and stress appear to be associated with greater frequency of sexual activity. Public health interventions should focus on educating elderly adults about their sexual health and how to seek medical help for their sexual problems. Public health professionals should also be educated on how to best assess sexual needs of the elderly adults.^

In this paper we present a deuterium excess (d) record from an ice core drilled on a small ice cap in Svalbard in 1997. The core site is located at Lomonosovfonna at 1255 m asl, and the analyzed time series spans the period 1400-1990 A.D. The record shows pronounced multidecadal to centennial-scale variations coherent with sea surface temperature changes registered in the subtropical to southern middle-latitude North Atlantic during the instrumental period. We interpret the negative trend in the deuterium excess during the 1400s and 1500s as an indication of cooling in the North Atlantic associated with the onset of the Little Ice Age. Consistently positive anomalies of d after 1900, peaking at about 1950, correspond with well-documented contemporary warming. Yet the maximum values of deuterium excess during 1900-1990 are not as high as in the early part of the record (pre-1550). This suggests that the sea surface temperatures during this earlier period of time in the North Atlantic to the south of approximately 45°N were at least comparable with those registered in the 20th century before the end of the 1980s. We examine the potential for a cold bias to exist in the deuterium excess record due to increased evaporation from the local colder sources of moisture having isotopically cold signature. It is argued that despite a recent oceanic warming, the contribution from this local moisture to the Lomonosovfonna precipitation budget is still insufficient to interfere with the isotopic signal from the primary moisture region in the midlatitude North Atlantic.

El objeto de estudio de este trabajo lo constituyen las relaciones entre las ideologías, la violencia organizada y el clima ideológico de la guerra fría durante las décadas de 1960 y 1970 en la Argentina. Se analizan, particularmente, tres corrientes ideológicas: el peronismo revolucionario, el peronismo ortodoxo y el conservadurismo. Estas corrientes son estudiadas a partir de dos categorías de análisis: en primer lugar, la identificación de actores políticos y sociales considerados relevantes y, en segundo lugar, los condicionamientos estructurales básicos, en los subsistemas político, ideológico y económico, que cada postura entendía como facilitadores, generadores o determinantes de la violencia.

En esta investigación se analizan las estrategias de reproducción social de pequeños productores mapuche-tehuelche del Paraje de Laguna Fría, en la Meseta Central de la Provincia de Chubut. En el estudio se busca dar cuenta de las estrategias de reproducción social, su lógica y configuración, a partir de analizar formas de acceso y manejo de recursos de que disponen e identificar las tensiones territoriales que condicionan los modos de vida (económica, social e histórica) de estos pequeños productores. La metodología incluyó la realización de encuestas y entrevistas a integrantes de las unidades domésticas de la Comunidad Aborigen de Laguna Fría y a técnicos de las instituciones presentes en el territorio. Se hicieron observaciones durante talleres participativos y se consultó información de fuentes primarias y secundarias. Los resultados muestran el modo en que las unidades domésticas de pequeños productores seleccionan, organizan y sistematizan un conjunto de prácticas a fin de garantizar su reproducción social en un contexto ambiental y socio histórico particular. Se concluye que las prácticas no sólo deben considerarse desde la lógica económico-productiva que las orienta, sino también, desde la lógica cultural y política relacionada a las nuevas formas de subordinación de los pequeños productores al capital y las resistencias individuales o colectivas que se generan. En definitiva, dar cuenta del sentido de las prácticas sociales en el marco de la dinámica del territorio como un campo social donde se tejen alianzas y conflictos entre actores diversos
