Defining risk acceptance criteria in occupational settings: A case study in the furniture industrial sector

The use of appropriate acceptance criteria in the risk assessment process for occupational accidents is an important issue but often overlooked in the literature, particularly when new risk assessment methods are proposed and discussed. In most cases, there is no information on how or by whom they were defined, or even how companies can adapt them to their own circumstances. Bearing this in mind, this study analysed the problem of the definition of risk acceptance criteria for occupational settings, defining the quantitative acceptance criteria for the specific case study of the Portuguese furniture industrial sector. The key steps to be considered in formulating acceptance criteria were analysed in the literature review. By applying the identified steps, the acceptance criteria for the furniture industrial sector were then defined. The Cumulative Distribution Function (CDF) for the injury statistics of the industrial sector was identified as the maximum tolerable risk level. The acceptable threshold was defined by adjusting the CDF to the Occupational, Safety & Health (OSH) practitioners’ risk acceptance judgement. Adjustments of acceptance criteria to the companies’ safety cultures were exemplified by adjusting the Burr distribution parameters. An example of a risk matrix was also used to demonstrate the integration of the defined acceptance criteria into a risk metric. This work has provided substantial contributions to the issue of acceptance criteria for occupational accidents, which may be useful in overcoming the practical difficulties faced by authorities, companies and experts.

Criação de valor em fusões e aquisições horizontais

O aumento verificado nos últimos anos em fusões e aquisições (F&A) resulta da opção dos gestores para fazer face ao aumento da pressão competitiva e ou à necessidade de crescimento rápido. A literatura sobre os efeitos dos processos de F&A é diversificada e as conclusões são contraditórias. Neste trabalho pretendemos verificar se o processo de F&A se traduz na criação de valor para o acionista da empresa adquirente. Como métrica de avaliação utilizamos o método de análise dos fluxos de caixa atualizados ou o Discounted Cash-Flow (DCF). Para o efeito efetuamos um estudo de caso que vai incidir sobre uma empresa seguradora portuguesa – A Lusitania Companhia de Seguros, S.A. – que recentemente adquiriu, por fusão por incorporação, a Real Seguros, S.A. Efetuamos uma análise de natureza quantitativa através dos dados do relatório e contas e encontramos evidência de que o desempenho diminuiu após a transação.
