This study analyses the determinants of the derivative instruments disclosure level by Portuguese listed companies. It is built a disclosure index to measure the disclosure level using the Consolidated Annual Reports for 2008. The hypotheses have been tested through a linear regression model using the disclosure index as the dependent variable and companies’ characteristics as independent variables. Multivariate results suggest that firm size, quality of the external auditor, belonging to PSI 20, the market to book value ratio and the percentage of capital hold by the board of directors are associated with the disclosure level.

La Unión Europea pretende renovar la Octava Directiva, entre otras razones, para reforzar la independencia de los auditores y abordar los conflictos de intereses inherentes al panorama actual. Este trabajo plantea conocer las expectativas sobre estas propuestas 2 concretando los factores que afectan, tanto positiva como negativamente, a que el auditor mantenga su independencia ante el cliente. Se comprueba que se perciben como factores negativos todos los relacionados con la dependencia económica y los conflictos de intereses en la negociación entre el auditor y la empresa. Sin embargo no se perciben como positivos los mecanismos empleados habitualmente como salvaguardas (como por ejemplo el Comité de Auditoría y la rotación), considerando que la independencia depende fundamentalmente de la persona del auditor y su carácter.

The European Union considers it appropriate to further discuss how to strengthen the independence of the auditors to address conflicts of interest inherent in the current scenario, characterized by factors such as the appointment of auditors for the audited company, low turnover or different service delivery to the audit. This paper aims to realize the expectations of the factors that affect, both positively and negatively, the auditor maintains its independence from the client.

Background: Surgical repair of pectus excavatum (PE) has become more popular due to improvements in the minimally invasive Nuss procedure. The pre-surgical assessment of PE patients requires Computerized Tomography (CT), as the malformation characteristics vary from patient to patient. Objective: This work aims to characterize soft tissue thickness (STT) external to the ribs among PE patients. It also presents a comparative analysis between the anterior chest wall surface before and after surgical correction. Methods: Through surrounding tissue segmentation in CT data, STT values were calculated at different lines along the thoracic wall, with a reference point in the intersection of coronal and median planes. The comparative analysis between the two 3D anterior chest surfaces sets a surgical correction influence area (SCIA) and a volume of interest (VOI) based on image processing algorithms, 3D surface algorithms, and registration methods. Results: There are always variations between left and right side STTs (2.54±2.05 mm and 2.95±2.97 mm for female and male patients, respectively). STTs are dependent on age, sex, and body mass index of each patient. On female patients, breast tissue induces additional errors in bar manual

As constantes mudanças que ocorrem no tecido empresarial instigam a instabilidade e desconfiança dos utilizadores da informação financeira. Neste contexto, os stakeholders procuram informação financeira fiável e clara para tomarem decisões ponderadas e com o menor risco possível. No sentido de satisfazer estas necessidades, os organismos profissionais de contabilidade têm manifestado grande preocupação em garantir a qualidade da informação financeira. A solução para o cumprimento dos objetivos anteriores deve passar pela realização de uma auditoria uma vez que esta função desempenha um importante papel no seio das empresas, quer no processo de prestação de contas, quer na redução das assimetrias de informação. No entanto, o processo de auditoria apresenta limitações que nem sempre são consideradas pelos utilizadores da informação financeira. Há, de facto, uma série de determinantes que pretendemos estudar neste trabalho que são suscetíveis de influenciar a opinião que o auditor irá emitir na certificação legal de contas (CLC). Para o efeito, debruçamo-nos sobre os relatórios e contas, referentes ao ano de 2011, de 50 empresas registadas na Comissão do Mercado de Valores Mobiliários (CMVM) para analisar a a influência dos seguintes fatores: tipo de Sociedade de Revisores Oficiais de Contas (SROC) a que o auditor pertence, o sexo e a experiência profissional do auditor, os honorários recebidos pelo auditor pelos serviços de Revisão Legal de Contas (RLC) e extra RLC. Os resultados revelaram que a opinião do auditor não é influenciada, significativamente, por nenhum dos fatores estudados, o que pode indiciar grande independência do auditor.
