Brazil has become the center of the spotlight of the whole world recently, amongst many other reasons, one of them was because it was chosen to host a series of mega sporting events - Pan American Games in 2007, Confederations Football Cup in 2013, Fifa Football World Cup 2014 Games and 2016 Olympic and Paralympic Games in 2016. However, little is known about the country's administrative governmental structure focused on sport policy. The available studies focus their analysis on the sport policies content, but not on the arrangement of its structural decision-making. The main aim of this article is indeed to describe, based on official documentation, the evolution and the current arrangements of the government responsible for the administrative structure for the planning and implementation of sports policies in Brazil. Thus, we tried to list the main problems arising from the organization of the Brazilian sports' management. These problems are: (1) inappropriate institutional structure in terms of human resources and obstacles to participation by other social actors beyond the officials (parliament and members of the Ministry of Sports) in the sports policy; (2) disarticulation between public institutions generating redundancies and conflicts of jurisdiction due to the poor division of labor between bureaucracy agencies; and (3) inadequate planning proved by the lack of organization of some institutions, and by the lack of assessment and continuity of public policies over time. Therefore, we must emphasize those problems from above, and due to these administrative arrangements, Brazilian sports' policy has big challenges in the sport development in this country, which includes the creation of a national "system" for sports and a priority investment in sport education.

A discussion of health policy in developing countries is presented. It argues that developing countries must adopt a progressive approach to health policy which rejects the two-tiered system of public and private health care. However, it also points out that ideology is not sufficient to maintain support. A progressive health system must utilize administrative and social and behavioral sciences to achieve effectiveness and efficiency in health care delivery. It cannot ignore these goals any more than a private health care system can.

The percentual distributions of selected sites of cancer cases according to origin, sex and age are compared. Data were obtained from the Registry of Cancer of S. Paulo (School of Public Health of the University of S. Paulo, Brazil). The reference period for inhabitants of Japanese descent was 1969/78 and for those of Brazilian descent, the period was 1969/75. Standardized Proportionate Incidence Ratios (SPIR) with approximate 95% Confidence Intervals (CI) were evaluated using age specific Incidence Ratios of S. Paulo, 1973, as standards. The results agree with findings of previous works on mortality, but show different patterns according to origin. The well known fact that some sub-groups of a population may be different from the overall group is once again brought to the fore. Attention should be drawn to the differences detected for stomach, skin and prostate, in males, and for stomach, skin, cervix and uterus in females.

Studies have been un dertaken into on the diversity and relative abundance of larvae of Anopheles (Nyssorhynchus) spp. in 22 permanent or temporary pools in an area of 70 km² in the eastern piedmont of the Venezuela Andes, between the mountains and the plains, an area in which malaria is refractory and A. nuñeztovari is present. Twelve species were identified, the most frequent, abundant and sympatric being A. triannulatus, A. albitarsis, A. nuñeztovari, A. oswaldoi and A. strodei. The samples from the permanent pools showed greater diversity of species and greater numbers of larvae than the samples from the temporary pools. The existence of the same larval associations in pools of other localities in the eastern piedmont of the Venezuelan Andes suggests the possibility of the making an ecological map of the breeding sites of A. nuñeztovari and for these anophelines in a region extending for 430 km.

We calculate the equilibrium thermodynamic properties, percolation threshold, and cluster distribution functions for a model of associating colloids, which consists of hard spherical particles having on their surfaces three short-ranged attractive sites (sticky spots) of two different types, A and B. The thermodynamic properties are calculated using Wertheim's perturbation theory of associating fluids. This also allows us to find the onset of self-assembly, which can be quantified by the maxima of the specific heat at constant volume. The percolation threshold is derived, under the no-loop assumption, for the correlated bond model: In all cases it is two percolated phases that become identical at a critical point, when one exists. Finally, the cluster size distributions are calculated by mapping the model onto an effective model, characterized by a-state-dependent-functionality (f) over bar and unique bonding probability (p) over bar. The mapping is based on the asymptotic limit of the cluster distributions functions of the generic model and the effective parameters are defined through the requirement that the equilibrium cluster distributions of the true and effective models have the same number-averaged and weight-averaged sizes at all densities and temperatures. We also study the model numerically in the case where BB interactions are missing. In this limit, AB bonds either provide branching between A-chains (Y-junctions) if epsilon(AB)/epsilon(AA) is small, or drive the formation of a hyperbranched polymer if epsilon(AB)/epsilon(AA) is large. We find that the theoretical predictions describe quite accurately the numerical data, especially in the region where Y-junctions are present. There is fairly good agreement between theoretical and numerical results both for the thermodynamic (number of bonds and phase coexistence) and the connectivity properties of the model (cluster size distributions and percolation locus).

We generalize the Flory-Stockmayer theory of percolation to a model of associating (patchy) colloids, which consists of hard spherical particles, having on their surfaces f short-ranged-attractive sites of m different types. These sites can form bonds between particles and thus promote self-assembly. It is shown that the percolation threshold is given in terms of the eigenvalues of a m x m matrix, which describes the recursive relations for the number of bonded particles on the ith level of a cluster with no loops; percolation occurs when the largest of these eigenvalues equals unity. Expressions for the probability that a particle is not bonded to the giant cluster, for the average cluster size and the average size of a cluster to which a randomly chosen particle belongs, are also derived. Explicit results for these quantities are computed for the case f = 3 and m = 2. We show how these structural properties are related to the thermodynamics of the associating system by regarding bond formation as a (equilibrium) chemical reaction. This solution of the percolation problem, combined with Wertheim's thermodynamic first-order perturbation theory, allows the investigation of the interplay between phase behavior and cluster formation for general models of patchy colloids.

A sample (n=124) of schizophrenic patients from a defined catchment area of the city os S.Paulo, Brazil, who had been consecutively admitted to hospital, was assessed for psychopathological status and social adjustment levels. Sociodemographic, socio-economic and occupational characteristics were recorded: almost 30% of the subjects had no occupation and received no social benefit, more than two-thirds had a monthly per capita income of US$ 100.00 or less. Sixty-five percent presented with Schneiderian firstrank symptoms. Nearly half the sample showed poor or very poor social adjustment in the month prior to admission. The most affected areas of social functioning were participation in the household activities, work and social withdrawal. The current mental health policy of promoting extra-mural care as an alternative to the previous hospital-based model will then mean the investment in a network of new community-based services, that give effective treatment and support to patients and their families. The need of further research into the current picture of mental disorders in the country is stressed.

The public sector is facing turbulent times and this also challenges the health professions who are expected to serve both the interests of the citizens and the cost-containment and austerity policies of governments. This article seeks to explore the changing role of the health professions. I introduce an approach on ‘citizen professionals’ as active players in the policy process and mediators between the state/policymakers and the citizens/patients. The aim is to highlight a transformative potential of professionalism and the connectedness with other sets of governance, like management. Empirical material from a German case study and a comparative European study serve to illustrate the arguments, drawing on policy analysis and secondary sources. The results bring the complexity of transformations and new emergent forms of professionalism into view that cannot be understood in traditional categories of conflict, exclusion and jurisdiction. Exploring the potential of the health professions to creatively respond to new challenges may reveal new opportunities for innovating healthcare policy beyond market and management.

Este artigo de natureza ensaística procura contribuir para o desenvolvimento de argumentos já apresentados a respeito de reconfigurações ideológicas nas políticas de saúde. A partir de dimensões analíticas discute-se o espaço e implicações da individualização do direito à saúde no contexto de maior liberalização dos mercados e de maior exposição ao investimento privado lucrativo. A individualização do direito à saúde assume-se como contrária aos princípios éticos e morais consolidados entre os países ocidentais a partir da 2ª metade do séc. XX, em que o acesso aos cuidados passa gradualmente a estar dependente das condições individuais das famílias, não obstante o pagamento de impostos e outros seguros. Não só passa a existir espaço para formas desiguais de acesso ao direito à saúde, como o princípio da utilização racional que baseia esta reconfiguração é uma crença managerialista falaciosa e, em larga medida, irrealista. Esta discussão é ilustrada a partir de dados da OCDE, os quais demonstram tendências díspares a respeito desta dinâmica.

The objective of this descriptive study was to map mental health research in Brazil, providing an overview of infrastructure, financing and policies mental health research. As part of the Atlas-Research Project, a WHO initiative to map mental health research in selected low and middle-income countries, this study was carried out between 1998 and 2002. Data collection strategies included evaluation of governmental documents and sites and questionnaires sent to key professionals for providing information about the Brazilian mental health research infrastructure. In the year 2002, the total budget for Health Research was US$101 million, of which US$3.4 million (3.4) was available for Mental Health Research. The main funding sources for mental health research were found to be the São Paulo State Funding Agency (Fapesp, 53.2%) and the Ministry of Education (CAPES, 30.2%). The rate of doctors is 1.7 per 1,000 inhabitants, and the rate of psychiatrists is 2.7 per 100,000 inhabitants estimated 2000 census. In 2002, there were 53 postgraduate courses directed to mental health training in Brazil (43 in psychology, six in psychiatry, three in psychobiology and one in psychiatric nursing), with 1,775 students being trained in Brazil and 67 overseas. There were nine programs including psychiatry, neuropsychiatry, psychobiology and mental health, seven of them implemented in Southern states. During the five-year period, 186 students got a doctoral degree (37 per year) and 637 articles were published in Institute for Scientic Information (ISI)-indexed journals. The investment channeled towards postgraduate and human resource education programs, by means of grants and other forms of research support, has secured the country a modest but continuous insertion in the international knowledge production in the mental health area.

Um dos principais problemas com que se deparam as sociedades actuais, e que é consequência da sua forma de se organizar prende-se com a mudança das características originais dos locais onde habitam e dos seus componentes como resultado das actividades humanas que transformam solos e águas em depósitos de resíduos. Entre as substâncias que são depositadas no meio físico, que requerem especial atenção, encontra-se o grupo dos metais pesados, uma vez que são considerados como perigosos pela sua toxicidade e potencial cancerígeno quando em contacto com populações ou ecossistemas. Destes metais, o crómio é um dos metais que requer especial atenção devido a sua relativa abundância como contaminante, e à periculosidade dos seus iões, em especial o Cr6+. Este trabalho pretende contribuir para o conhecimento dos fenómenos geoambientais associados à remediação de águas contaminadas com Cr6+ recorrendo ao ferro monovalente de forma a estabelecer parâmetros de aplicabilidade através de estudos laboratoriais baseados em ensaios em colunas.

Nos últimos dez a quinze anos temos assistido a um aumento do número de iniciativas com a participação da sociedade civil, no sentido de exercer pressão para a reformulação dos direitos sociais. Estes já não são tão vistos como direitos para aceder aos serviços estruturados e administrados pelo Estado (de acordo com o conceito de cidadania de Marshall), mas como uma reivindicação dos cidadãos para terem um papel ativo na definição das políticas públicas e dos serviços. Este debate tem sido muito intenso entre os cientistas sociais desde a década de 1980 e está bastante presente no sistema de cuidados de saúde. Vários estudos têm salientado a forte tensão entre o tecnicismo da medicina e a organização burocrática do sistema de saúde, por um lado, e o modelo de comunicação quotidiana, por outro lado. De facto, um dos temas centrais das reformas dos cuidados de saúde nos últimos 20 anos centrou-se na valorização da experiência e da perspetiva dos cidadãos. O artigo começa com um breve esboço das novas abordagens sociológicas em torno da relação entre os sistemas sociais e o mundo real – nas dimensões micro e macro; estrutura e ação. Assim, apresenta-se o estado da arte atual sobre a participação nos sistemas de saúde ocidentais, resultante da revisão da literatura, destacando as novas estratégias de envolvimento dos doentes bem como as questões relativas às críticas e às limitações. Para terminar, procede-se a uma reflexão acerca da complexidade da relação entre o sistema de cuidados de saúde e as associações de doentes e utentes.

This paper presents the study of the remediation of sandy soils containing six of the most common contaminants (benzene, toluene, ethylbenzene, xylene, trichloroethylene and perchloroethylene) using soil vapour extraction (SVE). The influence of soil water content on the process efficiency was evaluated considering the soil type and the contaminant. For artificially contaminated soils with negligible clay contents and natural organic matter it was concluded that: (i) all the remediation processes presented efficiencies above 92%; (ii) an increase of the soil water content led to a more time-consuming remediation; (iii) longer remediation periods were observed for contaminants with lower vapour pressures and lower water solubilities due to mass transfer limitations. Based on these results an easy and relatively fast procedure was developed for the prediction of the remediation times of real soils; 83% of the remediation times were predicted with relative deviations below 14%.

Soil vapor extraction (SVE) is an efficient, well-known and widely applied soil remediation technology. However, under certain conditions it cannot achieve the defined cleanup goals, requiring further treatment, for example, through bioremediation (BR). The sequential application of these technologies is presented as a valid option but is not yet entirely studied. This work presents the study of the remediation of ethylbenzene (EB)-contaminated soils, with different soil water and natural organic matter (NOMC) contents, using sequential SVE and BR. The obtained results allow the conclusion that: (1) SVE was sufficient to reach the cleanup goals in 63% of the experiments (all the soils with NOMC below 4%), (2) higher NOMCs led to longer SVE remediation times, (3) BR showed to be a possible and cost-effective option when EB concentrations were lower than 335 mg kgsoil −1, and (4) concentrations of EB above 438 mg kgsoil −1 showed to be inhibitory for microbial activity.
