    This paper is an essay that resulted from reflections on sustainable development and its connections with university extension programs and violence. The paper discusses the four extents of sustainable development - ethical, temporal, social, and practical and the ethical principles of sustainability, essential for a culture of peace. It proposes a new praxis in the university to reevaluate the institution departmentalization, in order to open space for the construction of a cross-disciplinary environment which will produce graduates prepared for a sustainable future. It introduces an extension program of the Federal University of Rio Grande do Sul (UFRGS), which studies violent behavior and acts to decrease the problem effectively. The work concludes that it is the university's role to educate professionals according to sustainable development values, prepared to act in an ethical and responsible way concerning natural and human resources, capable of understanding and interacting with the complexity of problems such as poverty, social inequities and violence, which threaten human rights and the future generations.Este é um trabalho de natureza ensaística, resultado de reflexões sobre o desenvolvimento sustentável e a sua conexão com as ações de extensão universitárias e a violência. Discute as quatro dimensões básicas do desenvolvimento sustentável - a ética, a temporal, a social e a prática - e os princípios éticos da sustentabilidade, necessários para uma cultura de paz. Propõe uma nova práxis universitária, em que a departamentalização da instituição seja repensada a fim de abrir espaço para a construção de um ambiente de atuação transdisciplinar, formador de profissionais preparados para um futuro sustentável. Apresenta um serviço da Universidade Federal do Rio Grande do Sul (UFRGS), que, por meio da ação de extensão Projeto Proteger, estuda o comportamento violento e age para diminuir efetivamente a violência. Conclui que é papel da universidade formar profissionais em compasso com os valores do desenvolvimento sustentável, preparados para agir de forma ética e responsável com os recursos naturais e humanos, capazes de entender e interagir com a complexidade de problemas como a pobreza, as desigualdades sociais e a violência, que ameaçam os direitos humanos e as futuras gerações

    INTRODUCTION: There are few published empirical data on the effects of COVID-19 on mental health, and until now, there is no large international study. MATERIAL AND METHODS: During the COVID-19 pandemic, an online questionnaire gathered data from 55,589 participants from 40 countries (64.85% females aged 35.80 ± 13.61; 34.05% males aged 34.90±13.29 and 1.10% other aged 31.64±13.15). Distress and probable depression were identified with the use of a previously developed cut-off and algorithm respectively. STATISTICAL ANALYSIS: Descriptive statistics were calculated. Chi-square tests, multiple forward stepwise linear regression analyses and Factorial Analysis of Variance (ANOVA) tested relations among variables. RESULTS: Probable depression was detected in 17.80% and distress in 16.71%. A significant percentage reported a deterioration in mental state, family dynamics and everyday lifestyle. Persons with a history of mental disorders had higher rates of current depression (31.82% vs. 13.07%). At least half of participants were accepting (at least to a moderate degree) a non-bizarre conspiracy. The highest Relative Risk (RR) to develop depression was associated with history of Bipolar disorder and self-harm/attempts (RR = 5.88). Suicidality was not increased in persons without a history of any mental disorder. Based on these results a model was developed. CONCLUSIONS: The final model revealed multiple vulnerabilities and an interplay leading from simple anxiety to probable depression and suicidality through distress. This could be of practical utility since many of these factors are modifiable. Future research and interventions should specifically focus on them

    Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

    We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

    Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

    Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe
