Understanding safety and production risks in rail engineering planning and protection

Much of the published human factors work on risk is to do with safety and within this is concerned with prediction and analysis of human error and with human reliability assessment. Less has been published on human factors contributions to understanding and managing project, business, engineering and other forms of risk and still less jointly assessing risk to do with broad issues of ‘safety’ and broad issues of ‘production’ or ‘performance’. This paper contains a general commentary on human factors and assessment of risk of various kinds, in the context of the aims of ergonomics and concerns about being too risk averse. The paper then describes a specific project, in rail engineering, where the notion of a human factors case has been employed to analyse engineering functions and related human factors issues. A human factors issues register for potential system disturbances has been developed, prior to a human factors risk assessment, which jointly covers safety and production (engineering delivery) concerns. The paper concludes with a commentary on the potential relevance of a resilience engineering perspective to understanding rail engineering systems risk. Design, planning and management of complex systems will increasingly have to address the issue of making trade-offs between safety and production, and ergonomics should be central to this. The paper addresses the relevant issues and does so in an under-published domain – rail systems engineering work.

Os Determinantes Socioculturais da Saúde e os Contextos Específicos da Pobreza, Minorias Étnicas e Imigrantes

Pretende-se neste artigo, reflectir sobre as condicionantes sociais da saúde particularmente relacionadas com os circuitos de pobreza, nomeadamente nos contextos relacionados com as minorias étnicas e os imigrantes. Dá-se particular atenção à importância do desenvolvimento de políticas de saúde baseadas na informação proporcionada pelas intervenções científicas, com base na necessidade de estabelecimento de parcerias entre diversos actores de intervenção comunitária em saúde profissionais de saúde, estudantes universitários, técnicos autárquicos, representantes das populações locais. Alerta-se ainda para a necessidade de desenhar projectos de educação e promoção da saúde, especialmente desenhados para a população imigrante, tendo em conta as suas particularidades culturais e simbólicas.
