Damage Theory

A reasonably safe reliability approach to a fatigue damage theory can be based on the fact that, in most cases involving the public safety, the designer can accept only very low probabilities of failure by fatigue. Thus we must be almost exclusively concerned with the lower left-hand tails of the associated distribution functions. An approach to damage theory is presented based on this concept and its possible utility reviewed. The Weibull distribution is utilized with three parameters. Suggestions are made as to needed fatigue testing.

The outbreak of COVID-19 has placed a heavy burden on society, threatening the future of the entire world as the pandemic has hit health systems and economic sectors hard. Where time moves fast, continuing curfews and lockdown is impossible. This paper assembles three main safety behaviors, social distancing, wearing a facemask, and hygiene in one model (PSC Triangle) to be practiced by the public. Integrating public safety compliance with these behaviors is the main recommendation to slow the spread of COVID-19. Although some concerns and challenges face these practices, the shifting of public behaviors to be more safety-centered is appropriate and available as an urgent desire exists to return to normal life on the one hand and the medical effort to find effective cure or vaccine that has not yet succeeded on the other hand. Recommendations to enhance public safety compliance are provided.

Due to the superior structure style, orthotropic steel bridge deck has been getting more and more widely practical application. The static and fatigue tests of the orthotropic steel bridge deck models were carried out in this research paper, which presented the fatigue damage developing laws, compared the test results with homogeneous test results in existing documents, and according to the relative fatigue accumulative damage theory, the fatigue accumulative damage equations of the sectional specimen and the whole specimen are respectively studied.

Violence Index

Os mecanismos de gestão da segurança pública são instrumentos administrativos que potencializam os resultados de políticas nessa área. É o caso dos Conselhos, Planos, Fundos e Secretarias Municipais de Segurança Pública, além das Guardas Municipais. O artigo tem como objetivo verificar se a adoção de tais mecanismos produz impacto nos indicadores de violência. Paratanto, foram construídos o Índice de Gestão Municipal da Segurança Pública e o Índice de Violência. A partir de análise de correlaçãoentre tais variáveis, aponta que o nível atual de adoção dos mecanismos de gestão avaliados é muito baixo em todas as unidades federativas do Brasil, e não consegue influenciar os níveis de violência. Conclui que, ao omitir-se de implementar mecanismos degestão da segurança pública, o poder municipal, como ente mais próximo da população, enfraquece uma estrutura administrativa quedeveria servir de base para as políticas públicas voltadas para a redução da violência no âmbito local.Palavras-chave: Poder municipal, gestão, políticas públicas, violência.MUNICIPAL MANAGEMENT OF THE PUBLIC SAFETY: responsibility of the Brazilian municipalities for combating violenceAbstract: Mechanisms of the public security management are administrative tools that have improved the policies results in this area. This is the case of the Councils, Plans, Funds and Public Safety Secretariats, besides Municipal Guards. The paper aims to verify whether the adoption of such mechanisms has impacts on the violence indicators. Therefore, were built the Municipal Public Security Management Index and Violence Index. From the analysis of correlation between these variables was observed that the present level of adoption of management mechanisms is very low in all federative units of Brazil, and does not influence the levels of violence. Concludes that to omit to implement mechanisms of public safety management, the municipal power, as nearest entity of the population, weakens the administrative structure which should be the basis of all local public security policies.Key words: Municipal government, management, public policies, violence.

On June 2nd, 2020, the Canadian Association for Security and Intelligence Studies (CASIS) Vancouver hosted its second digital roundtable event of the year titled, “Privacy and Security: Working Hand in Hand to Protect You Online.” This presentation featured Dr. Patrick Neal who has been involved in the public safety field since 1982. Dr. Neal’s presentation focused on the cohesiveness of privacy and security in the near future, privacy constructs, myths and harms of privacy, and privacy enhancing technologies. The subsequent roundtable discussion centered around Dr. Neal’s lecture in a question and answer period. APA Citation CASIS Vancouver. (2020).
