Beekeeping is recognized as promoter of assumptions and dimensions of sustainable development, supported by the triple bottle line – economic viability, social relevance and environmental prudence. Historically, it is strongly related with the central state of São Paulo. This work has as main objective to identify the profile of beekeeping in the this region, based on four municipalities (Araraquara, Descalvado, Rio Claro and São Carlos) in order to determine the main difficulties faced by beekeepersfor the sustainable development, pointing alternative interventions able to soften the effects of difficulties. It was used two different and complementary methodological strategies. The first one was a search with the databases (SEADE and IBGE) to obtain secondary data and quantitative regarding beekeeping in the region. The second one, it wasthrough field research with the beekeepers. The survey found that beekeeping in the region, presents an essentially familial and hereditary. Was also noticed the damage caused in the production, by limiting access to the region’s bee pastures and use of pesticides. In processing, it was found the extremely precarious conditions. At the institutional level, it was found the relative weakness of the beekeepers cooperatives, and the lack of support from local governments to consolidate activity.

The parliamentary representation in the Southern Cone integration is the main issue in this article, which analyzes some implications of the institutionalization of Mercosur Parliament (Parlasur). Consolidation and deepening of the integration process are related to the very weakness of congressional action under the Joint Parliamentary Committee and even the Parlasur. The hypothesis is that the creation of the Mercosur Parliament could contribute to the integration process only insofar as it could overcome the limitations experienced by the Joint Parliamentary Commission and go forward in building a democratic and representative body of regional integration.

Hypoglycemia is a well recognized cause of acute symptomatic seizures. The fact that hypoglycemia can cause peripheral neuropathy is less appreciated. We describe a case of insulinoma associated peripheral neuropathy. A 17 year-old previously healthy man was referred for investigation of refractory epilepsy. A history of recurrent seizures, slowly progressive weakness of his feet and hands, and weight gain was obtained. Physical examination showed signs of a chronic sensory-motor polyneuropathy. He was diagnosed with insulinoma and primary hyperparathyroidism, characterizing multiple endocrine neoplasia, type 1 syndrome. Cases of insulinoma associated peripheral neuropathy are very rare. The more characteristic clinical picture appears to be distal weakness, worse in the intrinsic hand and feet muscles, and no or mild sensory signs. Peripheral nervous system symptoms may not completely resolve, despite removal of the cause of hyperinsulinism/hypoglycemia and full reversion of central nervous system symptoms. Mechanisms underlying hypoglycemic neuropathy are still poorly understood. (C) 2011 Elsevier B.V. All rights reserved.

The association between autoimmune hepatitis and idiopathic inflammatory myopathies has been rarely described in literature. To our knowledge, there are only five reports of autoimmune hepatitis, all coursing with polymyositis. In the present work, we describe a female patient at the age of 58 with cutaneous lesions (heliotrope), progressive proximal muscle weakness of four limbs and constitutional symptoms for 12 months, and worsened two months ago. She had also been episodes of jaundice for five months. During hospitalization, after intense clinical investigation, the diagnosis of dermatomyositis and autoimmune hepatitis were defined, and the patient had a good clinical and laboratory response to corticosteroids and immunosuppressive.

The Peer-to-Peer network paradigm is drawing the attention of both final users and researchers for its features. P2P networks shift from the classic client-server approach to a high level of decentralization where there is no central control and all the nodes should be able not only to require services, but to provide them to other peers as well. While on one hand such high level of decentralization might lead to interesting properties like scalability and fault tolerance, on the other hand it implies many new problems to deal with. A key feature of many P2P systems is openness, meaning that everybody is potentially able to join a network with no need for subscription or payment systems. The combination of openness and lack of central control makes it feasible for a user to free-ride, that is to increase its own benefit by using services without allocating resources to satisfy other peers’ requests. One of the main goals when designing a P2P system is therefore to achieve cooperation between users. Given the nature of P2P systems based on simple local interactions of many peers having partial knowledge of the whole system, an interesting way to achieve desired properties on a system scale might consist in obtaining them as emergent properties of the many interactions occurring at local node level. Two methods are typically used to face the problem of cooperation in P2P networks: 1) engineering emergent properties when designing the protocol; 2) study the system as a game and apply Game Theory techniques, especially to find Nash Equilibria in the game and to reach them making the system stable against possible deviant behaviors. In this work we present an evolutionary framework to enforce cooperative behaviour in P2P networks that is alternative to both the methods mentioned above. Our approach is based on an evolutionary algorithm inspired by computational sociology and evolutionary game theory, consisting in having each peer periodically trying to copy another peer which is performing better. The proposed algorithms, called SLAC and SLACER, draw inspiration from tag systems originated in computational sociology, the main idea behind the algorithm consists in having low performance nodes copying high performance ones. The algorithm is run locally by every node and leads to an evolution of the network both from the topology and from the nodes’ strategy point of view. Initial tests with a simple Prisoners’ Dilemma application show how SLAC is able to bring the network to a state of high cooperation independently from the initial network conditions. Interesting results are obtained when studying the effect of cheating nodes on SLAC algorithm. In fact in some cases selfish nodes rationally exploiting the system for their own benefit can actually improve system performance from the cooperation formation point of view. The final step is to apply our results to more realistic scenarios. We put our efforts in studying and improving the BitTorrent protocol. BitTorrent was chosen not only for its popularity but because it has many points in common with SLAC and SLACER algorithms, ranging from the game theoretical inspiration (tit-for-tat-like mechanism) to the swarms topology. We discovered fairness, meant as ratio between uploaded and downloaded data, to be a weakness of the original BitTorrent protocol and we drew inspiration from the knowledge of cooperation formation and maintenance mechanism derived from the development and analysis of SLAC and SLACER, to improve fairness and tackle freeriding and cheating in BitTorrent. We produced an extension of BitTorrent called BitFair that has been evaluated through simulation and has shown the abilities of enforcing fairness and tackling free-riding and cheating nodes.

The thesis focuses on the link between education and poverty. The first part of the work investigates these concepts through a multidisciplinary study (History, Anthropology, Sociology, Psychology, Pedagogy) to show the complexity of the phenomena, and analyzes poverty considering it as an educational challenge. The second part presents the outcomes of a qualitative research about the role and the power that education has in the fight against poverty. The interviews and the focus groups with teachers and educators who work with the poor in several Italian cities and abroad (Denver and Los Angeles, Israel and Palestine), and the observations of the educational work done in some schools and services considered the "best practices" highlight the importance to re-educate our society, that is impoverished by the crisis of welfare state and the weakness of social networks. The final chapter is dedicated to a reflection on social justice, solidarity and sobriety, as pillars for Social Pedagogy in a society that cannot close its eyes to the inequalities that it generates.

The sensitivity of crime rates to social, economic and political influences has long aroused the interest of sociologists who have attempted to explain what kind of relationships might be associated with variations in crime rates between different social groups at different times. The earliest views were put forward by Emil Durkheim, and while later writers have developed (R.K. Merton, L. Srole, A, K. Cohen, etc.) have developed some aspects of his ideas further, his basic ideas of the divorce of the individual from normative standards and the lack of social integration are still valid. Ms. Voicu-Minea looked at the theoretical background in detail but then limited it to a specific social group, the family, asking first why certain individual within vulnerable families and/or negative social influences commit offences while others do not. In modern times the family has undergone massive structural and functional changes. Its former economic function, which once endowed it with a great capacity for social inclusion, has generally vanished, while its formerly crucial role in children's education has been massively reduced. These changes, which are still not complete, can lead to dysfunction and in certain social contexts such as that in post-communist Romanian society, this risk of dysfunction is still greater as unfavourably social circumstances more easily affect such families. The number of cases of juvenile delinquency in Romania has increased sharply ever since the end of the communist system and in 1996 reached the level of 18,317 cases. The sample examined included 1012 juvenile delinquents aged between 14 and 18, taken from all areas of Bucharest. Over 80% of charges related to theft, with more serious offences being relatively rare. The children underwent a series of psychological tests, accompanied by a questionnaire relating to family situation. The results showed that juvenile delinquency in Romania is overwhelmingly male, with 91.8% of offences being committed by boys. Two thirds of the research group were under the age of 16 and only just over one third attended school, with over half having left school before the legal age. While the majority of subjects had a lower than average level of education, they did not always recognise this, with two thirds seeing their level of education as being as good as or better than average. Nearly half the children (43%) did not live with both natural parents and majority came from families with three or more children. This applied both to their original families and to the families in which they were living at the time of the survey. The overwhelming majority of families were living in or around Bucharest, but under one third originated from there. Almost 25% of parents were under-schooled and around one third were unqualified workers. At least 30% of families lived in inadequate accommodation and family incomes were generally low. Ms. Voicu-Minea does however point out that over half the minors from the sample saw their family income as satisfactory or even more than satisfactory. When factors such as bad relationships between parents, corporal punishment, alcohol consumption and criminal records of family members were taken into account, the picture was bleak, making it understandable why over 36% of subjects had run away from home at least once, and in many cases repeatedly and for longer periods. The overwhelming majority of offences (80.8%) were committed in groups of between 2 and 11 persons, usually "friends" but in about 10% of cases member's of the family. IQ tests put about 75% of the sample at slightly under average, the difference being too slight to account for the behaviour problems of the majority. Personality tests, however, showed a different picture. Over 70% of those tested manifested an acute need of tenderness and a similar number a high level of potential aggressiveness. Almost half of the minors expressed such feelings as intolerance or a desire for revenge, and Ms. Voicu-Minea found a clear weakness of the Self. Around half the sample expressed sentiments of abandonment, renunciation and solitude.

We report on a 36-year-old man with a history of mild head trauma. The initial clinical findings and the CT-scan of the brain revealed no pathological result, although the patient suffered from weakness of the right arm and bilateral blindness. Those findings were interpreted as psychogenic disorder. Nine days later he developed an instable gait, a child like attitude, amnesia and enuresis. The CT-scan revealed a subacute bilateral occipital stroke in the region of the arteriae cerebri posteriors. No cause for the stroke was found. In spite of the rareness of cortical blindness in young people as a cause of stroke, a detailed medical history and clinical examination should always be performed, and by unclearness additional investigations should be considered.

Southeast Texas, including Houston, has a large presence of industrial facilities and has been documented to have poorer air quality and significantly higher cancer rates than the remainder of Texas. Given citizens’ concerns in this 4th largest city in the U.S., Mayor Bill White recently partnered with the UT School of Public Health to determine methods to evaluate the health risks of hazardous air pollutants (HAPs). Sexton et al. (2007) published a report that strongly encouraged analytic studies linking these pollutants with health outcomes. In response, we set out to complete the following aims: 1. determine the optimal exposure assessment strategy to assess the association between childhood cancer rates and increased ambient levels of benzene and 1,3-butadiene (in an ecologic setting) and 2. evaluate whether census tracts with the highest levels of benzene or 1,3-butadiene have higher incidence of childhood lymphohematopoietic cancer compared with census tracts with the lowest levels of benzene or 1,3-butadiene, using Poisson regression. The first aim was achieved by evaluating the usefulness of four data sources: geographic information systems (GIS) to identify proximity to point sources of industrial air pollution, industrial emission data from the U.S. EPA’s Toxic Release Inventory (TRI), routine monitoring data from the U.S. EPA Air Quality System (AQS) from 1999-2000 and modeled ambient air levels from the U.S. EPA’s 1999 National Air Toxic Assessment Project (NATA) ASPEN model. Further, once these four data sources were evaluated, we narrowed them down to two: the routine monitoring data from the AQS for the years 1998-2000 and the 1999 U.S. EPA NATA ASPEN modeled data. We applied kriging (spatial interpolation) methodology to the monitoring data and compared the kriged values to the ASPEN modeled data. Our results indicated poor agreement between the two methods. Relative to the U.S. EPA ASPEN modeled estimates, relying on kriging to classify census tracts into exposure groups would have caused a great deal of misclassification. To address the second aim, we additionally obtained childhood lymphohematopoietic cancer data for 1995-2004 from the Texas Cancer Registry. The U.S. EPA ASPEN modeled data were used to estimate ambient levels of benzene and 1,3-butadiene in separate Poisson regression analyses. All data were analyzed at the census tract level. We found that census tracts with the highest benzene levels had elevated rates of all leukemia (rate ratio (RR) = 1.37; 95% confidence interval (CI), 1.05-1.78). Among census tracts with the highest 1,3-butadiene levels, we observed RRs of 1.40 (95% CI, 1.07-1.81) for all leukemia. We detected no associations between benzene or 1,3-butadiene levels and childhood lymphoma incidence. This study is the first to examine this association in Harris and surrounding counties in Texas and is among the first to correlate monitored levels of HAPs with childhood lymphohematopoietic cancer incidence, evaluating several analytic methods in an effort to determine the most appropriate approach to test this association. Despite recognized weakness of ecologic analyses, our analysis suggests an association between childhood leukemia and hazardous air pollution.^

La obra vincula las instituciones, el orden público y la construcción de una ciudadanía en la Pampa Central con la extensión de propiedades de construcción del Estado que el gobierno federal intentaba concretar en los territorios nacionales -fines del siglo XIX-. Se analizan las instituciones, su constitución, funcionamiento e inconvenientes. Se reconstruyen las relaciones de la incipiente sociedad civil que estaba adquiriendo rasgos de "ciudadanía", pese a la limitación del derecho a la soberanía y representación política, por cuya razón se abocó al reducido poder local, a la conversión del Territorio en provincia y a la presión sobre las instituciones del Estado. Ciertos sectores sociales -vecinos propietarios- participaron en el poder y pudieron incidir en la disposición de un determinado orden público. Se descubre este entramado a través de la cuestión política, la constitución de la esfera pública, el papel de la prensa, y el accionar de sectores gubernamentales y particulares, especialmente en los conflictos sociales. Estas cuestiones se analizan con mayor profundidad en el estudio particular de una institución: la justicia letrada nacional con marcado poder en el Territorio. Se demuestra que esta institución ejerció un papel importante en la extensión de las propiedades que caracterizaron la construcción y consolidación del Estado. El protagonismo judicial a nivel nacional tuvo su correlación en el poder de los jueces y de los juzgados letrados territoriales, basado en: el carácter nacional de estos tribunales, el perfil profesional de sus miembros, una red social y política de los magistrados a nivel nacional y, la debilidad de las demás instituciones del Territorio. Este poder era reconocido y consolidado por la prensa y los vecinos -propietarios, comerciantes y profesionales- interesados en jerarquizar el papel de la justicia.

El objetivo de este trabajo es analizar el crecimiento del comercio minorista en Brasil teniendo en vista la ampliación del mercado interno de consumo que ha sido impulsada por la ampliación del sistema de crédito y por políticas estatales de redistribución de renta y de exención de impuestos. La expansión del mercado implica una profunda reestructuración a nivel productivo que abarca el sector industrial, comercial y de servicios y que se realiza por medio de una constante reorganización espacial y de la transformación gradual de los patrones de consumo. Una de las características principales del crecimiento del mercado interno de consumo es la tendencia a exacerbar las contradicciones centro-periferia generadas por la consolidación de procesos de concentración y centralización espacial de las actividades económicas en determinadas regiones del territorio brasilero.
