An Ethos Theory of Party Positions on European Integration: Poland and Beyond

Since 1989, five parliamentary elections have been the stage for the foundation and demise of political parties aspiring to govern the new democratic Polish state. The demise of the AWS before the 2001 elections after ten years of attempts to create a centre-right core party resulted in a new splintering of the right-wing, and the centre-right became again devoid of a pivotal formation. While Eurosceptic parties in average gain 8 percent of the vote, in the 2001 Polish parliamentary elections Eurosceptic parties gained around 20 percent of the vote. In Poland right-wing parties show an unusual propensity for Euroscepticism. The persistence and increased importance of nationalism in Poland, which has prevented the development of a strong Christian democratic party, effectively explains the levels of Euroscepticism on the right. After the autumn 2005 parliamentary elections the national conservative party, Law and Justice, formed a governing coalition with the national Catholic League of Polish Families, creating one of the first Eurosceptic governments. Although this work does not intend to provide a theorisation of party systems development, it shows that the context of European integration fostered nationalists’ divisiveness of, and provoked the splitting of the right the unusual propensity of parties for Euroscepticism makes Poland a paradigmatic case of the kind of conflicts over European integration emerging in Central and Eastern European party systems.

Renewable Power Sources

Of all of the sources of renewable energies available one can argue that the most abundant and accessible are solar power, radiation, and the energy of the tides (70 % of the earth surface is covered by water). The tidal wave energy hasn’t seen a widespread distribution yet, mainly due to the lack of interest of the governments, most of the coastal areas of the world are exclusive responsibility of the governments, thus not easily open for private venture. Considering solar power, there exist two main fields of application, land based systems and space based systems. The former systems are still in a very embryonic phase, with Japan being the lead researcher in the field, with an experimental satellite-power station to be launched before 2010. Land based systems, on the other hand, are well studied, with major research and application programs in all known forms of solar power production. Given a minimum value of incident radiation, and applying the appropriate system, (i.e. power plant type), for any given area the solar power becomes an income-producing industry.

On international cost-sharing of pharmaceutical R&D

Ramsey pricing has been proposed in the pharmaceutical industry as a principle to price discriminate among markets while allowing to recover the (fixed) R&D cost. However, such analyses neglect the presence of insurance or the fund raising costs for most of drug reimbursement. By incorporating these new elements, we aim at providing some building blocks towards an economic theory incorporating Ramsey pricing and insurance coverage. We show how coinsurance affects the optimal prices to pay for the R&D investment. We also show that under certain conditions, there is no strategic incentive by governments to set coinsurance rates in order to shift the financial burden of R&D. This will have important implications to the application of Ramsey pricing principles to pharmaceutical products across countries.

Saúde mental, qualidade de vida e acesso aos cuidados de saúde na comunidade brasileira de Lisboa

Introdução: A utilização de serviços de saúde tem implicações importantes para o estado de saúde das populações. As políticas de imigração adoptadas nos países de destino têm influência no estado de saúde das comunidades imigrantes. Políticas que limitam o acesso de imigrantes aos cuidados de saúde aumentarão a vulnerabilidade e os riscos na saúde. Apesar da imigração promover uma série de rupturas na vida do sujeito, migrar, por si só, não pode ser considerado como factor de risco no âmbito da saúde e da saúde mental. O peso dos determinantes socioeconómicos tem ganho relevância no estudo das migrações, estado de saúde geral e mental. Isto porque, em geral, os imigrantes estão em situação mais precária do que a população autóctone. O estatuto socioeconómico baixo, as condições precárias de habitação e de trabalho, a falta de suporte social e a irregularidade jurídica são indicadores de risco acrescido para a saúde mental. Neste sentido é um desafio de monta os governos estabelecerem medidas sustentadas e, simultaneamente, integradoras dos imigrantes. Em Portugal, considera-se que há escassez de estudos relacionados com a área das migrações e da saúde.Metodologia: Estudo exploratório, descritivo e transversal. A finalidade foi a de identificar o estado de saúde, saúde mental e qualidade de vida da comunidade brasileira residente em Lisboa e o seu acesso aos serviços de saúde. Este estudo teve como principais objectivos a caracterização sociodemográfica, a identificação de variáveis inerentes ao processo migratório, a identificação da auto-apreciação do estado de saúde, a caracterização do acesso aos cuidados de saúde, a identificação do grupo em provável sofrimento psicológico, a comparação entre os resultados dos imigrantes juridicamente regulares e irregulares e a comparação entre a população imigrante e a população portuguesa. Inicialmente, foi prevista a utilização da técnica de amostragem de propagação geométrica ou snowball, pois a amostra tornar-se-ia maior à medida que os próprios inquiridos identificam outros potenciais respondentes. Ao longo do estudo, a metodologia inicial mostrou-se insuficiente para estabelecer uma amostra mais representativa dos imigrantes juridicamente irregulares. Para este feito, foi utilizada a metodologia de amostragem por conveniência e o local escolhido para a recolha da amostra foi o Consulado do Brasil em Lisboa. O instrumento de recolha de dados empregue baseou-se no questionário utilizado no 4º Inquérito Nacional de Saúde. O MHI-5 (Mental Health Index 5) é um instrumento de saúde mental e é parte integrante do inquérito, sendo recomendado pela Organização Mundial de Saúde. Consta de cinco itens relativos à saúde mental e os resultados são classificados através de um indicador que mede a existência de provável sofrimento psicológico. Foram incluídos no estudo 213 brasileiros. De seguida, procedeu-se ao tratamento estatístico dos dados. Resultados: A população inquirida é jovem, a maior parte tem entre 18 e 44 anos. As mulheres representam mais de metade da amostra. A taxa de actividade é elevada e a taxa de desemprego é similar à nacional. A inserção laboral prioritária é nos segmentos pouco qualificados ou de semi-qualificação. Aproximadamente um terço dos inquiridos afirmou ser beneficiário do Sistema Nacional de Saúde. A autoapreciação do estado de saúde é classificada como bastante positiva, assim como a qualidade de vida. O provável sofrimento psicológico, definido no MHI-5 pelo ponto de corte no score 52, atinge 23,3% dos participantes. Os homens apresentam melhores resultados do que as mulheres. Além disso, para os valores mais baixos no MHI-5 foram encontradas relações com as longas jornadas de trabalho e o diagnóstico de doença crónica.Discussão: O presente estudo apresenta limitações em relação à dimensão da amostra e à provável existência de enviesamento pela ausência de aleatorização. Apesar da legislação portuguesa garantir o acesso aos serviços de saúde e garantir a equidade no caso dos imigrantes que fazem descontos para a Segurança Social, apenas um terço referiu ser beneficiário do Sistema Nacional de Saúde. Este dado pode ser justificado por factores como o cumprimento da lei por alguns serviços e, também, pela falta de conhecimento da legislação e da forma de funcionamento do Serviço Nacional de Saúde por parte dos imigrantes. O facto das mulheres representarem o maior grupo em provável sofrimento psicológico é consistente com a literatura. As hipóteses levantadas para explicar este resultado podem ser agrupadas em: artefactos metodológicos, causalidade biológica e determinação social. Em relação ao instrumento, é possível que o MHI-5 se comporte de forma diferente no que diz respeito ao género.-------------------------------------------Introduction: The utilization of health services has important implications for the health state of the populations. The immigration policies adopted in the destiny countries are going to influence the health state of immigrant communities. Policies that limit the access of immigrants to health care are going to increase the vulnerability and the risk factor in health. Although immigration promotes several disruptive actions in ones life, migrating, on its own, cannot be considered as a risk factor for health and mental health. The preponderance of the socioeconomic factors has gained relevance in the study of migrations and also in the study of general health state and mental health. This happens because, in general, immigrants are in a more unfavorable situation compared with the destiny country population. The low socioeconomic status, the poor working and housing conditions, the lack of social support and the juridical irregularity are indicators of the incremented risk to mental health. Therefore, it is a major challenge for governments to find sustainable, and simultaneously, integrative measures for the immigrants. The studies related with the migrations and health in Portugal were considered to be few.Methods: It is an exploratory, descriptive and transversal study. The purpose is to identify the health state, mental health, quality of life and the access to health care of the Brazilian community resident in Lisbon. In addition, this study has as main goals the sociodemographic characterization, the variables identification inherent to the migrating process, the identification of the self-appreciation of health state, the characterization of the access to health care, the identification of the group in probable psychological suffer, the comparison between the results of regular and irregular immigrants and the comparison between the immigrant population and the Portuguese population. Initially it was predicted the utilization of the geometric propagation or “snowball”, as sampling technique, because the sample becomes larger as one answerer identify other potential answering persons. Along with the study, the methodology has shown insufficient to establish a more representative sample of the irregular immigrants. For this latter case, it was used a convenient sample methodology and the place chosen for the sample gathering was the “Consulate of Brazil in Lisbon”. The instrument was based in the questionnaire used in the “4th National Health Inquiry”. The MHI-5 (Mental Health Index 5) is a mental health instrument which is part of the enquiry and it is recommended by the World Health Organization. There are five items related to mental health and the results are classified through an indicator which measures the existence of a probable psychological suffer. It were included 213 Brazilian in the study. After, the statistical treatment of the data took place.Results: The answering population is young and the majority is between the 18 and 44 years of age. The women represent more than one half of the sample. The activity rate is high and the unemployment rate is similar to the national one. The priority labor insertion is in the few qualified or of semi-qualification segments. Approximately, one third of the answering people has stated to be beneficiary of the National Health System. The self-appreciation of the health state as well as the quality of life are classified as fairly positive ones. The probable psychological suffer, as defined in the MHI-5 through the cut point in the score below or equal to 52, reaches 23,3% of the sample population. Men show the better results than women. Further, for the lower values of MHI-5 it was found a relation with the long work periods and chronic disease diagnostic. Discussion: The present study evidences limitations in relation to the sample dimension and in relation to the existence of biases due to the lack of randomness. Although the Portuguese legislation guarantees the access to health services and the equality in the cases of the immigrants that do their Social Security discounts, only one third has mentioned to be beneficiary of the National Health System. This can be justified by several facts such as the non-fulfillment of law by some national services or the lack of knowledge of the legislation or the functioning process of the National Health System. Women representing the bigger group in probable psychological suffer has been coherent with the literature review. The hypothesis set to explain this result might be grouped in: methodological artifacts, biologic cause and social determination. In relation to the instrument used, it may be that MHI-5 behaves in a different way in respect to gender.

Probabilistic maintenance and optimization strategies for deteriorating civil infrastructures

In developed countries, civil infrastructures are one of the most significant investments of governments, corporations, and individuals. Among these, transportation infrastructures, including highways, bridges, airports, and ports, are of huge importance, both economical and social. Most developed countries have built a fairly complete network of highways to fit their needs. As a result, the required investment in building new highways has diminished during the last decade, and should be further reduced in the following years. On the other hand, significant structural deteriorations have been detected in transportation networks, and a huge investment is necessary to keep these infrastructures safe and serviceable. Due to the significant importance of bridges in the serviceability of highway networks, maintenance of these structures plays a major role. In this paper, recent progress in probabilistic maintenance and optimization strategies for deteriorating civil infrastructures with emphasis on bridges is summarized. A novel model including interaction between structural safety analysis,through the safety index, and visual inspections and non destructive tests, through the condition index, is presented. Single objective optimization techniques leading to maintenance strategies associated with minimum expected cumulative cost and acceptable levels of condition and safety are presented. Furthermore, multi-objective optimization is used to simultaneously consider several performance indicators such as safety, condition, and cumulative cost. Realistic examples of the application of some of these techniques and strategies are also presented.

Defining health law or the edgewood syndrome

ABSTRACT - The authors’ main purpose is to present ideas on defining Health Law by highlighting the particularities of the field of Health Law as well as of the teaching of this legal branch, hoping to contribute to the maturity and academic recognition of Health Law, not only as a very rich legal field but also as a powerful social instrument in the fulfillment of fundamental human rights. The authors defend that Health Law has several characteristics that distinguish it from traditional branches of law such as its complexity and multidisciplinary nature. The study of Health Law normally covers issues such as access to care, health systems organization, patients’ rights, health professionals’ rights and duties, strict liability, healthcare contracts between institutions and professionals, medical data protection and confidentiality, informed consent and professional secrecy, crossing different legal fields including administrative, antitrust, constitutional, contract, corporate, criminal, environmental, food and drug, intellectual property, insurance, international and supranational, labor/employment, property, taxation, and tort law. This is one of the reasons why teaching Health Law presents a challenge to the teacher, which will have to find the programs, content and methods appropriate to the profile of recipients which are normally non jurists and the needs of a multidisciplinary curricula. By describing academic definitions of Health Law as analogous to Edgewood, a fiction house which has a different architectural style in each of its walls, the authors try to describe which elements should compose a more comprehensive definition. In this article Biolaw, Bioethics and Human Rights are defined as complements to a definition of Health Law: Biolaw because it is the legal field that treats the social consequences that arise from technological advances in health and life sciences; Bioethics which evolutions normally influence the shape of the legal framework of Health; and, finally Human Rights theory and declarations are outlined as having always been historically linked to medicine and health, being the umbrella that must cover all the issues raised in the area of Health Law. To complete this brief incursion on the definition on Health Law the authors end by giving note of the complex relations between this field of Law and Public Health. Dealing more specifically on laws adopted by governments to provide important health services and regulate industries and individual conduct that affect the health of the populations, this aspect of Health Law requires special attention to avoid an imbalance between public powers and individual freedoms. The authors conclude that public trust in any health system is essentially sustained by developing health structures which are consistent with essential fundamental rights, such as the universal right to access health care, and that the study of Health Law can contribute with important insights into both health structures and fundamental rights in order to foster a health system that respects the Rule of Law.-------------------------- RESUMO – O objectivo principal dos autores é apresentar ideias sobre a definição de Direito da Saúde, destacando as particularidades desta área do direito, bem como do ensino deste ramo jurídico, na esperança de contribuir para a maturidade e para o reconhecimento académico do mesmo, não só como um campo juridicamente muito rico, mas, também, como um poderoso instrumento social no cumprimento dos direitos humanos fundamentais. Os autores defendem que o Direito da Saúde tem diversas características que o distinguem dos ramos tradicionais do direito, como a sua complexidade e natureza multidisciplinar. O estudo do Direito da Saúde abrangendo normalmente questões como o acesso aos cuidados, a organização dos sistemas de saúde, os direitos e deveres dos doentes e dos profissionais de saúde, a responsabilidade civil, os contratos entre instituições de saúde e profissionais, a protecção e a confidencialidade de dados clínicos, o consentimento informado e o sigilo profissional, implica uma abordagem transversal de diferentes áreas legais, incluindo os Direitos contratual, administrativo, antitrust, constitucional, empresarial, penal, ambiental, alimentar, farmacêutico, da propriedade intelectual, dos seguros, internacional e supranacional, trabalho, fiscal e penal. Esta é uma das razões pelas quais o ensino do Direito da Saúde representa um desafio para o professor, que terá de encontrar os programas, conteúdos e métodos adequados ao perfil dos destinatários, que são normalmente não juristas e às necessidades de um currículo multidisciplinar. Ao descrever as várias definições académicas de Direito da Saúde como análogas a Edgewood, uma casa de ficção que apresenta um estilo arquitectónico diferente em cada uma de suas paredes, os autores tentam encontrar os elementos que deveriam compor uma definição mais abrangente. No artigo, Biodireito, Bioética e Direitos Humanos são descritos como complementos de uma definição de Direito da Saúde: o Biodireito, dado que é o campo jurídico que trata as consequências sociais que surgem dos avanços tecnológicos na área da saúde e das ciências da vida; a Bioética cujas evoluções influenciam normalmente o quadro jurídico da Saúde; e, por fim, a teoria dos Direitos Humanos e as suas declarações as quais têm estado sempre historicamente ligadas à medicina e à saúde, devendo funcionar como pano de fundo de todas as questões levantadas na área do Direito da Saúde. Para finalizar a sua breve incursão sobre a definição de Direito da Saúde, os autores dão ainda nota das complexas relações entre este último e a Saúde Pública, onde se tratam mais especificamente as leis aprovadas pelos governos para regular os serviços de saúde, as indústrias e as condutas individuais que afectam a saúde das populações, aspecto do Direito da Saúde que requer uma atenção especial para evitar um desequilíbrio entre os poderes públicos e as liberdades individuais. Os autores concluem afirmando que a confiança do público em qualquer sistema de saúde é, essencialmente, sustentada pelo desenvolvimento de estruturas de saúde que sejam consistentes com o direito constitucional da saúde, tais como o direito universal ao acesso a cuidados de saúde, e que o estudo do Direito da Saúde pode contribuir com elementos

War and propaganda in the XXth Century

Propaganda represented the sacrifice of soldiers in war and praised the power of the country. It has been around these images that all over the world entire populations were mobilized on the expectation of victory. Through the static image of printed posters or the newspaper news projected in cinemas all over the globe, governments sought to promote a patriotic spirit, encouraging the effort of individual sacrifice by sending a clear set of messages that directly appealed to the voluntary enlistment in the armies, messages that explained the important of rationing essential goods, of the intensification of food production or the purchase of war bonds, exacerbating feelings, arousing emotions and projecting an image divided between the notion of superiority and the idea of fear of the opponent. From press, in the First World War, to radio in World War II, to television and cinema from the 1950s onwards, propaganda proved to be a weapon as deadly as those managed by soldiers in the battlefield. That’s why it is essential to analyse and discuss the topic of War and Propaganda in the Twentieth Century.
