O Século XXI e o desafio da contemporaneidade, implicam para o Serviço Social diferentes horizontes teóricos e diferentes abordagens de prática, no enfrentamento da «questão social» e na promoção de conceções de mudança social. Com o objetivo de entender o imanente e o explícito no questionamento dos fundamentos normativos e dos fundamentos que sustentam a crítica no Serviço Social, e ainda de localizar no amplo debate da Teoria Social Contemporânea as influencias dos pensadores, da Teoria Social clássica, da Escola de Frankfurt e mais recentemente pelas teorias pós estruturalistas, as reflexões do presente artigo abarcam do contexto de surgimento das teorias críticas ao Serviço Social crítico contemporâneo, seus principios e fundamentos e por fim a teoria crítica pósmoderna na sua dimensão ontológica, epistemológica e metodológica.

<i>Background:</i> To evaluate the prevalence of hepatitis B virus (HBV) and associated factors in 949 heroin users (HU): injectors (IHUs) and non-injectors (NIHUs). <i>Methods:</i> Cross-sectional study; structured questionnaire administered by computer-assisted personal interviewing and audio computer-assisted self-interviewing; dry blood samples analysed for the hepatitis B core antigen and hepatitis B surface antigen; bivariate analysis and logistic regression. <i>Results:</i> The prevalence of infection was significantly higher in IHUs (22.5%) than in NIHUs (7.4%) in the three cities. In the logistic analysis of male IHUs, infection was found to be associated with living in Seville, age over 25, foreign nationality, having had a sexual partner who traded sex, hepatitis C virus infection, and having injected for more than 5 years. In female IHUs, HBV infection was associated with age over 25, having injected as the first main route of administration, and having begun to inject before 18 years of age. In NIHUs, the associated factors were female gender, foreign nationality and having been tattooed. In young IHUs, the prevalence of HBV infection remains four times higher than in the general population of the same age group. <i>Conclusion:</i> The vaccination strategy urgently needs to be reinforced and redesigned to achieve acceptable control of the HBV infection in the most vulnerable groups, with special attention to immigrants.

Machado-Joseph disease (MJD), also known as spinocerebellar ataxia type 3, is the most common of the dominantly inherited ataxias worldwide and is characterized by mutant ataxin-3 aggregation and neuronal degeneration. There is no treatment available to block or delay disease progression. In this work we investigated whether trehalose, a natural occurring disaccharide widely used in food and cosmetic industry, would rescue biochemical, behavioral and neuropathological features of an in vitro and of a severe MJD transgenic mouse model. ; This work was funded by BioBlast Pharma, the ERDF through the Regional Operational Program Center 2020, Competitiveness Factors Operational Program (COMPETE 2020) and National Funds through FCT (Foundation for Science and Technology) - SFRH/BD/87404/2012, BrainHealth2020 projects (CENTRO-01-0145-FEDER-000008), ViraVector (CENTRO-01-0145FEDER-022095), CortaCAGs (POCI-01-0145-FEDER-016719), SpreadSilenc‑ing POCI-01-0145-FEDER-029716 and POCI-01-0145-FEDER-007440, as well as the SynSpread, ESMI and ModelPolyQ under the EU Joint ProgramNeurodegenerative Disease Research (JPND), the last two co-funded bythe European Union H2020 program, GA No. 643417; by National Ataxia Foundation (USA), the American Portuguese Biomedical Research Fund (APBRF) and the Richard Chin and Lily Lock Machado–Joseph Disease Research Fund. ; info:eu-repo/semantics/publishedVersion

International audience ; In January 2020, a stakeholder workshop was organized as a knowledge sharing strategy among European stalked barnacle fisheries. Management of this fishery differs greatly among regions and ranges from less organized and governed at large scales (>100 km, coasts of SW Portugal and Brittany in France) to highly participatory systems which are co-managed at small spatial scales (10′s km and less, Galicia and Asturias). Discussions revealed that poaching is ubiquitous, hard to eradicate, and adapts to all types of management. The stakeholders identified some key management initiatives in the fight against poaching: granting professional harvesters with exclusive access to the resource, increasing social capital among harvesters through tenure systems (e.g. Territorial Use Rights in Fisheries) that empower them as stewards of their resource and intensification of surveillance with the active participation of the harvesters. Furthermore, increased cooperation between fishers associations and regional fisheries authorities, improved legal frameworks, adoption of new technologies and the implementation of market-based solutions can also help coping with this systemic problem.

Este libro configura un aporte sustancial para entender, desde un prisma distante de las concepciones hegemónicas en la academia, las dinámicas de lucha y las disputas en torno a lo público que signan la realidad contemporánea de América Latina y el Caribe. Un continente éste que, desde la perspectiva de los pueblos y clases subalternas que lo han forjado y habitan, ha sido renombrado como Abya Yala, Patria Grande o Nuestra América, todos ellos significantes que cargan una historia en común y una identidad cultivada al calor de las resistencias contra el despojo, la violencia y la explotación de un capitalismo neocolonial asentado en un entronque de patriarcados, y cuya unidad en la diversidad fue moldeada borgeanamente más a partir del espanto que del amor. Los capítulos que integran esta compilación auscultan el subsuelo de nuestras sociedades, hurgando en sus recovecos y márgenes para identificar, tornar comprensibles y potenciar aquellos procesos de creación, fortalecimiento y/o recuperación de lo público que, difícilmente, salgan en las tapas de diarios o los programas de televisión, salvo que acontezcan en ellos actos "delictivos" o represiones monumentales.
