Construção de uma responsabilidade europeia além-fronteiras

The suppression of internal border controls has led the European Union to establish a mechanism for determining the Member State responsible for examining each asylum application, with the main intention of deterring asylum seekers from lodging multiple applications and guaranteeing that it will be assessed by one of the States – the Dublin System. Even though it holds on a variety of criteria, the most commonly used is the country of first entrance in the EU. The growing migrating flows coming mainly from Northern Africa have thus resulted in an incommensurable burden over the border countries. Gradually, countries like Greece, Bulgaria and Italy have lost capability of providing adequate relief to all asylum seekers and the records of fundamental rights violations related to the provision of housing and basic needs or inhuman detention conditions started piling up. To prevent asylum seekers who had already displaced themselves to other Member States from being transferred back to countries where their human dignity is questionable, the European Court of Human Rights and the Court of Justice have developed a solid jurisprudence determining that when there is a risk of serious breach of fundamental rights all transfers to that country must halt, especially when it is identified with systemic deficiencies in the asylum system and procedures. This reflexion will go through the jurisprudence that influenced very recent legislative amendments, in order to identify which elements form part of the obligation not to transfer under the Dublin System. At last, we will critically analyze the new rising obligation, that has clearly proven insufficient in light of the international fundamental rights framework that the Member States and the EU are bound to respect, proposing substantial amendments with a view to reach a future marked by high solidarity and global responsibility from the European Union.

Portugal no conselho de segurança das Nações Unidas

The United Nations is an international organization that was created after World War II, whose main objective is to promote cooperation, social and economic development, as well as to ensure international peace and security. The Member States are key actors in the international political system. For that reason they have strategic interests in what regards taking part in the international organizations. They see it as an opportunity to achieve those goals. The United Nations Security Council has a very important role in preserving international peace and security. It is the organ of the United Nations in which fifteen member states are represented: five permanently and ten non-permanently, being that the latter are elected for two years. Participating in the Security Council is a unique opportunity for middle powers like Portugal to promote their national interests and to increase their international visibility. In addition, they can contribute to the world’s destiny during their mandate period. Portugal has exercised his third term as a non-permanent member of the Security Council in 2011-2012 biennium, defeating Canada after a successful campaign carried out by the Portuguese diplomacy. This study analyses the participation of Portugal in the Security Council´s 2011-2012 biennium. It will focus the application process and election and the role of Portugal in the Security Council, especially in its the presidency and its intervention in the presidency of the Sanctions Committee on Libya. Its aim is to show the impact of Portuguese participation in the Security Council for international peace and security, as well as the geopolitical importance for the country of being part of the Security Council.

O filme “A Gaiola Dourada”: reflexões sobre o regresso em força da emigração portuguesa e a ‘portugalidade’ de uma gaiola (cada vez menos) dourada

A história de um casal de emigrantes portugueses em França bateu, no verão de 2013, recordes de audiência nas salas de cinema. O filme “A Gaiola Dourada”, de Ruben Alves, recuperou a temática da emigração portuguesa, numa altura em que esta atingiu o boom registado nos anos 1960. Recorrendo ao seu percurso, o realizador refere-se à ‘portugalidade’ como alegada ‘pertença a Portugal’, que assume como um cliché, e utiliza de forma humorística vários estereótipos associados aos emigrantes portugueses, através dos quais é mostrada alguma vergonha que os filhos dos emigrantes sentem em relação ao comportamento dos pais, trazendo ao de cima os contrastes com a sociedade onde vivem. A grande ficção reside no regresso ao país de origem, concretizando o sonho da grande maioria dos emigrantes, mas subvertendo a lógica: no filme, não são os pais que voltam a Portugal, mas os filhos, que aparentemente pouco se identificam com o país dos progenitores. “A Gaiola Dourada” reintroduziu o debate sobre a emigração em Portugal, aproveitando a crise económica para refletir sobre o seu regresso em força, bem como traçar o perfil dos novos emigrantes. Será que os portugueses na ‘diáspora’ ainda reavivam a chama ‘lusitana’ (Gonçalves, 2009)? E será que a partilha do nome ‘Portugal’ basta para sublinhar uma alegada identidade nacional (Sobral, 2012)?

Les traces de pneumatiques en sciences forensiques : de l'analyse chimique à l'évaluation de la force probante

This work is focused on the development of a methodology for the use of chemical characteristic of tire traces to help answer the following question: "Is the offending tire at the origin of the trace found on the crime scene?". This methodology goes from the trace sampling on the road to statistical analysis of its chemical characteristics. Knowledge about the composition and manufacture of tread tires as well as a review of instrumental techniques used for the analysis of polymeric materials were studied to select, as an ansi vi cal technique for this research, pyrolysis coupled to a gas Chromatograph with a mass spectrometry detector (Py-GC/MS). An analytical method was developed and optimized to obtain the lowest variability between replicates of the same sample. Within-variability of the tread was evaluated regarding width and circumference with several samples taken from twelve tires of different brands and/or models. The variability within each of the treads (within-variability) and between the treads (between-variability) could be quantified. Different statistical methods have shown that within-variability is lower than between-variability, which helped differentiate these tires. Ten tire traces were produced with tires of different brands and/or models by braking tests. These traces have been adequately sampled using sheets of gelatine. Particles of each trace were analysed using the same methodology as for the tires at their origin. The general chemical profile of a trace or of a tire has been characterized by eighty-six compounds. Based on a statistical comparison of the chemical profiles obtained, it has been shown that a tire trace is not differentiable from the tire at its origin but is generally differentiable from tires that are not at its origin. Thereafter, a sample containing sixty tires was analysed to assess the discrimination potential of the developed methodology. The statistical results showed that most of the tires of different brands and models are differentiable. However, tires of the same brand and model with identical characteristics, such as country of manufacture, size and DOT number, are not differentiable. A model, based on a likelihood ratio approach, was chosen to evaluate the results of the comparisons between the chemical profiles of the traces and tires. The methodology developed was finally blindly tested using three simulated scenarios. Each scenario involved a trace of an unknown tire as well as two tires possibly at its origin. The correct results for the three scenarios were used to validate the developed methodology. The different steps of this work were useful to collect the required information to test and validate the underlying assumption that it is possible to help determine if an offending tire » or is not at the origin of a trace, by means of a statistical comparison of their chemical profile. This aid was formalized by a measure of the probative value of the evidence, which is represented by the chemical profile of the trace of the tire. - Ce travail s'est proposé de développer une méthodologie pour l'exploitation des caractéristiques chimiques des traces de pneumatiques dans le but d'aider à répondre à la question suivante : «Est-ce que le pneumatique incriminé est ou n'est pas à l'origine de la trace relevée sur les lieux ? ». Cette méthodologie s'est intéressée du prélèvement de la trace de pneumatique sur la chaussée à l'exploitation statistique de ses caractéristiques chimiques. L'acquisition de connaissances sur la composition et la fabrication de la bande de roulement des pneumatiques ainsi que la revue de techniques instrumentales utilisées pour l'analyse de matériaux polymériques ont permis de choisir, comme technique analytique pour la présente recherche, la pyrolyse couplée à un chromatographe en phase gazeuse avec un détecteur de spectrométrie de masse (Py-GC/MS). Une méthode analytique a été développée et optimisée afin d'obtenir la plus faible variabilité entre les réplicas d'un même échantillon. L'évaluation de l'intravariabilité de la bande de roulement a été entreprise dans sa largeur et sa circonférence à l'aide de plusieurs prélèvements effectués sur douze pneumatiques de marques et/ou modèles différents. La variabilité au sein de chacune des bandes de roulement (intravariabilité) ainsi qu'entre les bandes de roulement considérées (intervariabilité) a pu être quantifiée. Les différentes méthodes statistiques appliquées ont montré que l'intravariabilité est plus faible que l'intervariabilité, ce qui a permis de différencier ces pneumatiques. Dix traces de pneumatiques ont été produites à l'aide de pneumatiques de marques et/ou modèles différents en effectuant des tests de freinage. Ces traces ont pu être adéquatement prélevées à l'aide de feuilles de gélatine. Des particules de chaque trace ont été analysées selon la même méthodologie que pour les pneumatiques à leur origine. Le profil chimique général d'une trace de pneumatique ou d'un pneumatique a été caractérisé à l'aide de huitante-six composés. Sur la base de la comparaison statistique des profils chimiques obtenus, il a pu être montré qu'une trace de pneumatique n'est pas différenciable du pneumatique à son origine mais est, généralement, différenciable des pneumatiques qui ne sont pas à son origine. Par la suite, un échantillonnage comprenant soixante pneumatiques a été analysé afin d'évaluer le potentiel de discrimination de la méthodologie développée. Les méthodes statistiques appliquées ont mis en évidence que des pneumatiques de marques et modèles différents sont, majoritairement, différenciables entre eux. La méthodologie développée présente ainsi un bon potentiel de discrimination. Toutefois, des pneumatiques de la même marque et du même modèle qui présentent des caractéristiques PTD (i.e. pays de fabrication, taille et numéro DOT) identiques ne sont pas différenciables. Un modèle d'évaluation, basé sur une approche dite du likelihood ratio, a été adopté pour apporter une signification au résultat des comparaisons entre les profils chimiques des traces et des pneumatiques. La méthodologie mise en place a finalement été testée à l'aveugle à l'aide de la simulation de trois scénarios. Chaque scénario impliquait une trace de pneumatique inconnue et deux pneumatiques suspectés d'être à l'origine de cette trace. Les résultats corrects obtenus pour les trois scénarios ont permis de valider la méthodologie développée. Les différentes étapes de ce travail ont permis d'acquérir les informations nécessaires au test et à la validation de l'hypothèse fondamentale selon laquelle il est possible d'aider à déterminer si un pneumatique incriminé est ou n'est pas à l'origine d'une trace, par le biais d'une comparaison statistique de leur profil chimique. Cette aide a été formalisée par une mesure de la force probante de l'indice, qui est représenté par le profil chimique de la trace de pneumatique.

Durcissement des lois sociales et santé des migrants forcés: trois ans après (a Loi sur l'asile (LAsi) [Social policy hardening and forced immigrant's health: 3 years after the Asylum Law (LAsi)'s introduction].

In the canton de Vaud, General Practioners (GPs) caring for asylum seekers under the "aide d'urgence" regime can ask for an adaptation of their housing conditions, by filling out a specific form and addressing it to the medical commission responsible for advising the EVAM (the housing institution for asylum seekers) on these issues. The forms addressed to the commission are indicative of a worrisome state of health in this population, especially for mental health. More than 70% report at least one psychiatric diagnosis. Most frequent are anxiety and depressive disorders, as well as many posttraumatic stress disorders, associated with traumatic events both in the country of origin and in Switzerland. Adapting the housing conditions, based on vulnerabilities that the GP has specifically documented, may contribute to improve the health of the most vulnerable asylum seekers.

Estudi comparatiu del sòl d'una vinya de Sant Pere de Ribes

Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. Anàlisi comparatiu de diferents propietats del sòl d’una vinya on s’ha observat que els peus presenten un creixement desigual. A partir d'una observació a simple vista de les plantes de la vinya i del sòl sobre el qual es desenvolupen, es proposa la hipòtesi de que el sòl pot ser un factor determinant per aquest creixement desigual. Després de fer una recerca bibliogràfica sobre l’edafologia, les propietats del sòl i els tipus de sòl que es poden trobar als voltants de Sant Pere de Ribes, l’autora ha fet una selecció de propietats físico-químiques que poden estar més relacionades amb el creixement de les plantes. Després de fer el mostreig i seguir els protocols de laboratori s’han analitzat els resultats i s’han redactat les conclusions. Les propietats estudiades han permès determinar els tipus de sòl, uns sòls de textures entre franco-arenoses i areno-franques. S’ha trobat també una correlació entre les diverses propietats estudiades: un sòl de porositat elevada, que presenta valors alts de velocitat d’infiltració i per tant amb baixa capacitat de retenció d’aigua disponible, no sembla el sòl ideal per al desenvolupament de les plantes de vinya. A partir del treball es plantegen noves incògnites sobre les adaptacions dels ceps a aquests tipus de sòl o sobre la qualitat del raïm que s'hi pot desenvolupar.

Histopathological alterations induced by non-viable cells and biochemical fractions from Paracoccidioides brasiliensis in mice

Non-viable cells and biochemical fractions from Paracoccidioides brasiliens were obtained for experimental inoculation in mice and posterior histopatological analysis. Dead total fungus, total fungus disrupted by sonorous waves, lipids of the fungus, supernatant of the lipid purification, integral and disrupted fungus free of lipids were obtained. The six preparations arised from masses of lyophilized yeasts of a recent isolate of P. brasiliensis (strain JT-1) and from a "Pool" equitably constituted by four strains maintained in laboratory for a long time (SN, 2, 18 and 192). Different doses of the 12 preparations were intraperitonially inoculated and histopathological analysis were done 30 days later. This analysis showed that all the inoculated preparations gave origin to inflamatory foci, except the one designated "supernatant of lipid purification". The alterations were detected exclusively in the liver of the animals and occurred from the smallest dose tested (1 mg), with exception of the lipids of the fungus, where the foci appeared only from a 3 mg dose onwards. No difference in the capacity of inducing histopathological alterations was found between the preparations obtained from the recent isolate (JT-1) and from the older ones ("Pool"). On the other hand, an increase of the number of inflammatory foci in function of the inoculated dose was observed.

Dengue situation in Brazil by year 2000

Dengue virus types 1 and 2 have been isolated in Brazil by the Department of Virology, Instituto Oswaldo Cruz, in 1986 and 1990 respectively, after many decades of absence. A successful continental Aedes aegypti control program in the Americas, has been able to eradicate the vector in most countries in the 60's, but the program could not be sustained along the years. Dengue viruses were reintroduced in the American region and the infection became endemic in Brazil, like in most Central and SouthAmerican countries and in the Caribbean region, due to the weaning of the vector control programs in these countries. High demographic densities and poor housing conditions in large urban communities, made the ideal conditions for vector spreading. All four dengue types are circulating in the continent and there is a high risk of the introduction in the country of the other two dengue types in Brazil, with the development of large epidemics. After the Cuban episode in 1981, when by the first time a large epidemic of dengue hemorrhagic fever and dengue shock syndrome have been described in the Americas, both clinical presentations are observed, specially in the countries like Brazil, with circulation of more than one dengue virus type. A tetravalent potent vaccine seems to be the only possible way to control the disease in the future, besides rapid clinical and laboratory diagnosis, in order to offer supportive treatment to the more severe clinical infections.

Risk factors for positive tuberculin skin tests among migrant and resident children in Lausanne, Switzerland.

SETTING: Ambulatory paediatric clinic in Lausanne, Switzerland, a country with a significant proportion of tuberculosis (TB) among immigrants. AIM: To assess the factors associated with positive tuberculin skin tests (TST) among children examined during a health check-up or during TB contact tracing, notably the influence of BCG vaccination (Bacille Calmette Guérin) and history of TB contact. METHOD: A descriptive study of children who had a TST (2 Units RT23) between November 2002 and April 2004. Age, sex, history of TB contact, BCG vaccination status, country of origin and birth outside Switzerland were recorded. RESULTS: Of 234 children, 176 (75%) had a reaction equal to zero and 31 (13%) tested positive (>10 mm). In a linear regression model, the size of the TST varied significantly according to the history of TB contact, age, TB incidence in the country of origin and BCG vaccination status but not according to sex or birth in or outside Switzerland. In a logistic regression model including all the recorded variables, age (Odds Ratio = 1.21, 95% CI 1.08; 1.35), a history of TB contact (OR = 7.31, 95% CI 2.23; 24) and the incidence of TB in the country of origin (OR = 1.01, 95% CI 1.00; 1.02) were significantly associated with a positive TST but sex (OR = 1.18, 95% CI 0.50; 2.78) and BCG vaccination status (OR = 2.97, 95% CI 0.91; 9.72) were not associated. CONCLUSIONS: TB incidence in the country of origin, BCG vaccination and age influence the TSTreaction (size or proportion of TST > or = 10 mm). However the most obvious risk factor for a positive TST is a history of contact with TB.

Squamous cell carcinoma in 6 patients with chronic discharging osteomyelitis: Is it really rare?

Introduction: Development of a squamous cell carcinoma (Marjolin's ulcer) is a rare but well-known complication of chronic discharging osteomyelitis. A high index of suspicion and highquality of histopathological examination are paramount in order to make the correct diagnosis. Methods: During a 15-year period (1993 and 2008), patients with long-standing chronic osteomyelitis with clinical symptoms of >1 year of duration, were retrospectively reviewed. Included were patients with histologically confirmed squamous-cell carcinoma associated with chronic wound overlying the site of chronic osteomyelitis. Clinical features and treatment approaches of these patients were analyzed. Results: During the study period, 6 patients were identified (2 women and 4 men) aged 52 to 67 years (mean 59 years). All patients had a long history of chronic discharging osteomyelitis (12, 19, 21, 30, 39 and 40 years), localized in the lower (5 patients) or upper extremitiy (1 patient). All tumors were histologically highly-differentiated squamous-cell carcinomas involving the deep soft tissues and the bone. 5 of 6 patients were initially misdiagnosed as chronic bone infection since bacteria were isolated in wound swabs, including Staphylococcus aureus (n = 3), Escherichia coli (n = 1) and Staphylococcus epidermidis (n = 1). Treatment consisted of major amputation in 4 patients and radical surgical excision in 2 patients refusing amputation. 4 patients were lost to follow-up due to return to their country of origin, the remaining 2 patients were without signs of tumor recurrence (both after major amputation). Conclusion: Malignant transformation of is a rare, but serious complication of long-standing discharging chronic osteomyelitis. All 6 patients were diagnosed after >10 years of persistent or recurrent wounds. It should be particularly suspected in case of a pathological fracture, development of exophytic mass and changes in local pattern of the ulcers itself. Multiple biopsies, including deep soft tissues and bone, are recommended to distinguish between chronic osteomyelitis, pseudoepitheliomatous hyperplasia and highly-differentiated squamous cell carcinoma. Early diagnosis and a team approach (orthopaedic and plastic surgeon) are crucial for optimal management of the patient

Urban design proposes for the norwegian cities

Alta is the biggest city in the country of Finnmark. The area of study, Bossekop, is situated 4km from the city centre. It has some commercial areas, offices, hotels and housing, mostly single family housing. The most important Norwegian road, E6 goes through Bossekop, there for it has a big traffic flow. The concept builds on the idea of two axis, one local leading from the local sports development area into the centre core, and one on a higher level, the E6. In Bodø, after analysing carefully the surroundings we reached the conclusion that it is posssible to conserve a lot of the green as well as offering the municipalities the chance to develop with several housing typologies. Nature should be preserved and with this connect directly the mountain to the sea, using the existing creek to make the water connection. In order to keep a big part of this land untouched, we suggest that the rest of the site can be developed quite densely in one of the areas and then continuously fading out in direction of the mountains. Finnsnes is an important communication point for the region with its good connections. In that way it is becoming a central point for commerce and leisure. The concept is based on the wish from the municipality of Lenvik to look upon the city’s connection to the surrounding sea and green areas, together with the wish to make the pedestrian access better and the car traffic lighter., and in that way improve the conditions in the city
