Determinants of social security pensions expenditure in Portugal

In most European countries Social Security (SS) systems are characterized as Pay-asyou- go systems. Their sustainability is being challenged with demographic changes, namely population ageing. Portugal’s population is ageing rapidly being one of the countries where this problem is more critical. With the growing debate on this topic several public choice models have been developed so as to explain SS size. In this work project there is an attempt to understand whether these models contribute to better explain Social security expenditure with pensions (SSEP) and to establish the need of finding ways to reduce present commitment with pension expenditure in Portugal.

Assessing the role of social networks on migrant labor market outcomes: Evidence from a representative immigrant survey

What role do social networks play in determining migrant labor market outcomes? We examine this question using data from a random sample of 1500 immigrants living in Ireland. We propose a theoretical model formally predicting that immigrants with more contacts have additional access to job offers, and are therefore better able to become employed and choose higher paid jobs. Our empirical analysis confirms these findings, while focusing more generally on the relationship between migrants’ social networks and a variety of labor market outcomes (namely wages, employment, occupational choice and job security), contrary to the literature. We find evidence that having one more contact in the network is associated with an increase of 11pp in the probability of being employed and with an increase of about 100 euros in the average salary. However, our data is not suggestive of a network size effect on occupational choice and job security. Our findings are robust to sample selection and other endogeneity concerns.

The characteristics of social entrepreneurship business models in Portugal

This work project is based on the MIES (Map of Innovation and Social Entrepreneurship in Portugal) database and it aims to understand the characteristics of social business models in the context of the portuguese market, by determining whether they follow the proposed characteristics by John Elkington and Pamela Hartigan, and then adding to their matrix. Furthermore, it tries to determine success patterns by comparing a group of successful social ventures with a group of less successful ones, with the objective of increasing the knowledge of social entrepreneurship as it applies to Portugal and provide a framework for future study.

Young adult Brazilian beauty consumers perception of Lancôme and the effectiveness of social media relationhips with local celebrities on their purchase intention

The aim of this research is to evaluate if a premium beauty brand, in this case, Lancôme, can influence positively the purchase intention from Brazilian young adults, between 18 and 29 years old, consumers of beauty products, by initiating a relationship with a local celebrity or “it” girl on social media. This hypothesis has not been tested, and this research is a first attempt of evaluating it. Additionally, the consumer behavior, brand preferences and social media activeness of this age segment in Brazil are further studied as important insights for beauty brands to conquer these consumers. Results did not confirm the positive influence of local celebrities on this age segment’s purchase intention but several suggestions are made for future research to revisit this topic. Furthermore, there is a significant brand love for M.A.C., an international Lancôme competitor, amongst this target, as well as a probable price sensitivity facing premium beauty brands.

The Portuguese language version of social phobia and Anxiety Inventory: analysis of items and internal consistency in a Brazilian sample of 1,014 undergraduate students

OBJECTIVE: Theoretical and empirical analysis of items and internal consistency of the Portuguese-language version of Social Phobia and Anxiety Inventory (SPAI-Portuguese). METHODS: Social phobia experts conducted a 45-item content analysis of the SPAI-Portuguese administered to a sample of 1,014 university students. Item discrimination was evaluated by Student's t test; interitem, mean and item-to-total correlations, by Pearson coefficient; reliability was estimated by Cronbach's alpha. RESULTS: There was 100% agreement among experts concerning the 45 items. On the SPAI-Portuguese 43 items were discriminative (p < 0.05). A few inter-item correlations between both subscales were below 0.2. The mean inter-item correlations were: 0.41 on social phobia subscale; 0.32 on agoraphobia subscale and 0.32 on the SPAI-Portuguese. Item-to-total correlations were all higher then 0.3 (p < 0.001). Cronbach's alphas were: 0.95 on the SPAI-Portuguese; 0.96 on social phobia subscale; 0.85 on agoraphobia subscale. CONCLUSION: The 45-item content analysis revealed appropriateness concerning the underlying construct of the SPAI-Portuguese (social phobia, agoraphobia) with good discriminative capacity on 43 items. The mean inter-item correlations and reliability coefficients demonstrated the SPAI-Portuguese and subscales internal consistency and multidimensionality. No item was suppressed in the SPAI-Portuguese but the authors suggest that a shortened SPAI, in its different versions, could be an even more useful tool for research settings in social phobia.

Trans-cultural aspects of social anxiety disorder and related conditions: a Brazilian case series and a review of international clinical studies

Cross-cultural studies have much to teach clinicians and researchers alike about psychopathology in general and about social anxiety disorder (SAD) in particular. Unfortunately, little is known about the degree and the mechanisms through which cultural environment may influence clinical manifestations of SAD. OBJECTIVE: Our objective was to identify culture-related clinical patterns in SAD and related disorders. METHODS: We described socio-demographic and clinical characteristics of a sample of 62 adult outpatients with SAD seen at a university clinic for anxiety and depressive disorders in Rio de Janeiro, Brazil, and compared them with those reported in clinical samples from North America, Europe, Asia and Oceania identified through a systematic review in Medline, PsychINFO, and LILACS. RESULTS: Our comparison of trans-cultural features of SAD lends partial support to Heimberg's (1997) contention that the majority of socio-demographic features and symptoms of this disorder are relatively independent of geographic and cultural differences. CONCLUSION: Patients with SAD were almost universally characterized by: 1) a predominance of males in clinical samples; 2) early onset of the disorder; 3) high educational attainment; and 4) great frequency of comorbidities.

Efectos de Territorio y Estrategias Familiares de Reproducción Social. El caso del Barrio Las playas de la ciudad de Villa María - Córdoba. Effects of Land and family strategies of social reproduction. The case of the neighborhood ´Las Playas´ in the city of Villa María - Córdoba.

Nuestro proyecto plantea analizar los recursos materiales y simbólicos que ponen en juego las familias pobres, en el marco de su reproducción social, a fin de evaluar en qué medida sus estrategias contribuyen a superar o reproducir las condiciones de pobreza hipotetizando que las prácticas sociales de las agentes en situación de pobreza, incluyen limitaciones conformadas por la estructura patrimonial disponible, como potencialidades inscriptas en la trayectoria colectiva y el estado de los instrumentos de reproducción del barrio, considerado como parte del sistema de estrategias de reproducción de sus unidades domésticas. En ese sentido la comprensión de las estrategias materiales y simbólicas que ponen en juego las familias pobres, nos ofrecerá una comprensión acabada de la problemática en cuestión a los efectos de lograr una incidencia mayor a la hora de la implementación de políticas públicas destinadas a este grupo poblacional, y grupos poblacionales similares. La inteligibilidad de este escenario social, puede ser aprehendida fundamentalmente, desde las posibilidades abiertas por las herramientas de tipo cualitativas, sin embargo la metodología utilizada en este proyecto de investigación considera la triangulación de inter-metodológica como recurso fundamental a fin de dar cuenta tanto de la dimensión explicativa como comprensiva de los problemas sociales a estudiar. La muestra es teórica intencional, sus alcances se definen por criterio de saturación teórica. Unidades de recolección: unidades familiares en situación de pobreza que viven en el barrio Las Playas, instituciones formales y no formales que conforman los instrumentos de reproducción social. En el trabajo de campo se profundizarán las estrategias de: 1- Observación a partir de la construcción de guías para la mayor precisión de un registro de tipo etnográfico; 2- Entrevistas semi-estructuradas y abiertas a diferentes familias del barrio seleccionadas a partir de la técnica denominada "Bola de Nieve" la cual provee un alcance exhaustivo en el territorio determinado; 3- Entrevista a informantes clave relacionados con ONGs e Instituciones Estatales actuantes en el barrio, referentes barriales y sindicales, punteros políticos, etc. Los datos obtenidos en el trabajo de campo deben relevar información que garantice el registro de las diversas miradas de los participantes y controlar la diferenciación entre los datos originales y las propias interpretaciones (Mendizábal, 2006). por lo cual la triangulación inter-metodológica, posibilitará articular reflexivamente los resultados cuantitavos y cualitativos. Se prevé la transferencia de resultados a través de publicaciones individuales o colectivas sobre los resultados obtenidos así como la presentación preliminar de los mismos en congresos y conferencias. Asimismo, se organizarán seminarios con los sectores de la sociedad civil que se trabaje en los que se espera discutir los resultados obtenidos.
