The entering at the University requires new social skills and their deficits may bring to students academic and interpersonal diffi culties. Few studies have addressed the infl uence of undergraduate periods and gender diff erences regarding social skills shown by college students, including frequency and quality which they occur and previous and consequent interaction variables. The main objective of this article is to describe the social skills shown by college students over undergraduate years. For specifi c objectives this study intends (a) the comparison of student groups in diff erent years (fi rst/second; fi rst/third; second/third) of full-time and nocturne periods, of men and women and (b) the presentation of functional analysis of interactions, considering the most frequent behaviors and contexts. For that, 85 students of Design course were analyzed through the following instruments: the Social Skills Questionnaire to College Students, Behaviors and Contexts; and the Social Skills Inventory (SSI). The results indicate diff erences between men and women and between full-time students and nocturne ones, and the greatest diff erences were in comparison between years, indicating that the fi rst and second years require greater investments in interventions, because they present greater diffi culties in communication behaviors, expressiveness and confl ict resolution. Furthermore, implications, limitations and suggestions for research are discussed.

The aging process involves challenges in meeting social needs, economic and health. Physiopathological changes and socio-economic predispose the elderly population at nutritional risk. The monitoring of nutritional status predict some complications of obesity or malnutrition, and is a tool for health care. The objective to know the nutritional status and risk of chronic diseases of the elderly in geriatric institutions and volunteers. The elderly population of 3 geriatric institutions (n=122) and non-institutionalized elderly (n=75) were evaluated. The body mass index was evaluated according to Nutrition Screening Initiative. For waist circumference, was used the World Health Organization criteria. For statistical analysis, chi-square was used. A high proportion of obesity (46%) was observed. The underweight affects 4% and 20% of noninstitutionalized and institutionalized, respectively. The frequency of the risk of diseases associated with obesity was higher among non-institutionalized. Hypertension affects more than 50% of the elderly. The nutritional status was different between the two situations, with high incidence of overweight and visceral adiposity, in volunteers, and wasting among institutionalized. The data emphasize that it is necessary special attention and appropriate measures to prevent morbidity and mortality and to improve quality of life.

Gramsci é um autor da atualidade, teórico da mundialização do capitalismo, mas ainda desconhecido, mesmo no campo do marxismo, entre as suas tendências dominantes. Pensar a globalização, o século XXI, a nova conjuntura política nos quadros da contemporaneidade é um desafio intelectual da maior relevância que tem, em Gramsci – certamente para surpresa de uns e negação de outros –, uma de suas fontes mais estimulantes e reveladoras. É fascinante desvendar em seus escritos teses indispensáveis para refletirmos alguns dos principais temas do momento em horizontes mundiais.

Herein, it was investigated for the first time the electro-oxidation of ethanol on Pt and PtRu electrodeposits in acidic media by using in situ surface enhanced infrared absorption spectroscopy with attenuated total reflection (ATR-SEIRAS). The experimental setup circumvents the weak absorbance signals related to adsorbed species, usually observed for rough, electrodeposited surfaces, and allows a full description of the CO coverage with the potential for both catalysts. The dynamics of adsorption-oxidation of CO was accessed by ATR-SEIRAS experiments (involving four ethanol concentrations) and correlated with expressions derived from a simple kinetic model. Kinetic analysis suggests that the growing of the CO adsorbed layer is nor influenced by the presence of Ru neither by the concentration of ethanol. The results suggest that the C-C scission is not related to the presence of Ru and probably happens at Pt sites.

Check-up is a frequent motivation for patients to see their general practitioner. The challenge lies in the choice of screening tools to accomplish an efficient, individual and age-adapted approach. In this article we review evidence-based screening methods, whose efficacy has been demonstrated by randomized clinical trials, as well as their application in clinical practice. While cardiovascular check-up has a high grade of evidence for nearly all patients, counselling to lifestyle change except for smoking cessation has been proved with lower evidence. In contrast, relatively new is the fact that ultrasound to screen for an abdominal aortic aneurysm is useful among men smokers or past smokers between 65 and 75 years old.

A common training plan in general internal medicine was a brave enterprise started in 2011 in accordance with the common objectives of the Swiss Society of General Medicine and the Swiss Society of Internal Medicine. The next challenge will be the dissolution of the two Societies and therefore the creation of an unique new association in 2015. This is an extraordinary opportunity to bring together the specific qualities of each association and to create a new society. Issues, objectives and secondary benefits expected from the creation of the largest national society of a medical discipline are explored as a joint discussion in this article.

La gestion durable des ressources naturelles est actuellement perçue comme une condition essentielle pour le développement durable, et surtout pour les pays en développement comme Madagascar. Face à la dégradation continue des ressources naturelles et surtout forestières, diverses stratégies sont adoptées par l’état malgache, dont l’extension des aires protégées qui veut allier la protection intégrale de certaines parties des ressources, et la satisfaction des besoins des populations riveraines. Le Code des Aires Protégées constitue un outil destiné à la gestion de ces aires de conservation. Toutefois, l’élaboration du plan d’aménagement ne prend pas souvent en compte des paramètres tels que l’augmentation de la population et les besoins qui s’en suivent, ou bien la participation de ces populations au processus d’élaboration et de mise en oeuvre du plan. Le défi est d’arriver à intégrer ces deux logiques de protection et de satisfaction des besoins de la population locale en réalisant des plans d’aménagement et de gestion concertés. Le cas du fokontany Ambohibary Sokafana dans le Corridor Anjozorobe Angavo est étudié pour identifier les paramètres à considérer si on veut atteindre cet objectif : paramètres écologiques et socio-économiques influençant la gestion des ressources forestières, critères permettant de définir la participation des acteurs dans cette gestion. Une revue des ouvrages spécifiques traitant du sujet ainsi que des observations et rencontres avec les divers acteurs sur terrain ont été menées afin de pouvoir identifier ces divers paramètres. Les analyses ont permis d’avancer deux scénarii qui traduisent l’intégration de la protection des forêts et la satisfaction des besoins en bois et en produits vivriers des populations riveraines, en tenant compte des motivations de ces dernières à participer au processus d’appropriation du plan d’aménagement et de gestion.

To increase the efficiency of equine semen, it could be useful to split the artificial insemination dose and refreeze the redundant spermatozoa. In experiment I, semen of 10 sires of the Hanoverian breed, with poor and good semen freezability, was collected by artificial vagina, centrifuged, extended in INRA82 at 400 × 106 sperm/mL, and automatically frozen. After this first routinely applied freezing program, semen from each stallion was thawed, resuspended in INRA82 at 40 × 106 sperm/mL, filled in 0.5-mL straws, and refrozen. These steps were repeated, and sperm concentration was adjusted to 20 × 106 sperm/mL after a third freezing cycle. Regardless of stallion freezability group, sperm motility and sperm membrane integrity (FITC/PNA-Syto-PI-stain) decreased stepwise after first, second, and third freezing (62.3% ± 9.35, 24.0% ± 15.4, 3.3% ± 4.34, P ≤ .05; 29.6% ± 8.64, 14.9% ± 6.38, 8.3% ± 3.24, P ≤ .05), whereas the percentage of acrosome-reacted cells increased (19.5% ± 7.59, 23.9% ± 8.51, 29.2% ± 6.58, P ≤ .05). Sperm chromatin integrity was unaffected after multiple freeze/thaw cycles (DFI value: 18.6% ± 6.6, 17.2% ± 6.84, 17.1% ± 7.21, P > .05). In experiment II estrous, Hanoverian warmblood mares were inseminated with a total of 200 × 106 spermatozoa of two stallions with either good or poor semen freezability originating from the first, second, and third freeze/thaw cycle. First-cycle pregnancy rates were 4/10, 40%; 1/10, 10%; and 0/10, 0%. In conclusion, as expected, sperm viability of stallion spermatozoa significantly decreases as a consequence of multiple freezing. However, sperm chromatin integrity was not affected. Pregnancy rates after insemination of mares with refrozen semen are reduced.

Los crímenes sexuales en general, y la violación en particular, suelen concebirse como una situación que involucra únicamente a dos personas: la víctima y su atacante. Sin embargo, los expedientes judiciales vinculados a estos delitos muestran un universo complejo de actores, que no ;se agota en aquel binomio. El presente trabajo se enfoca en algunas de esas ocasiones donde aquella lógica se demuestra incorrecta, mostrando cómo la justicia lidia con aquel desafío desde el discurso jurídico, analizando imágenes y concepciones que abogados y médicos expresan, afirman ;o discuten en relación al comportamiento esperado de hombres y mujeres, así como la situación de la justicia frente a crímenes que se alejan de la "normalidad" reconocida
