Observational research on golf-related injuries

The determination of aetiological factors in sports injuries is challenging. Recently, investigators have devoted significant attention to this topic. A reasonable amount of studies provides information on the occurrence, aetiology, and severity of golf-related injuries. However, gaps of evidence still limit the understanding of the injury problem in golf and the comparability of epidemiological findings. Observational studies using surveys and medical records were reviewed. Surveys are suited to find precise occurrence patterns of golf-related injuries, but fail to adequately ascertain the levels of exposure and aetiological factors. Due to the proximity to the injury event, medical records are able to clearly identify the aetiology and severity of golf-related injuries. While reviewing observational studies using surveys a comment was provided on the methodological quality and risk of bias. Overall, these studies seem to be disturbed on their ability to produce generalizations and comparison of study findings. With the information obtained from reviewing observational studies and the collaboration of a panel of internationally recognised experts on golf science and sports injury research, a web-based bilingual questionnaire was developed and tested for one of the provided languages. The bilingual nature of the questionnaire is also expected to facilitate the acceptance of the scientific community and enable the translation to different languages. A standardised questionnaire applied in different cultural contexts is expected to help and further improve the comparability of epidemiological findings. The questionnaire was proficient in capturing information on golf-related injuries and participation habits of golfers. While using a wider outcome definition focusing on any type of physical complaints, episodes of injury could be recognized despite onset and level of severity. Questions on the need for medical attention, time loss, and impact on performance also enabled additional categorisation of severity.

Factores determinantes das exportações portuguesas para Espanha : uma análise ao nível da empresa

Este estudo analisa a evolução das exportações portuguesas para Espanha e os seus factores determinantes no período 2004-2008, tendo por base uma amostra das 97 maiores empresas exportadoras para Espanha. O estudo utiliza vários indicadores económico-financeiros para caracterizar estas empresas e é feita a comparação entre as 5 maiores empresas e 5 pequenas e médias empresas (PMEs) da amostra. A análise evidencia a concentração geográfica destas empresas nos distritos de Porto e Aveiro e o melhor desempenho das grandes empresas em termos de produtividade, rendibilidade dos capitais próprios e salário médio quando comparadas com as PMEs. Quanto ao estudo econométrico, que utiliza dados em painel, consideraram-se como variáveis explicativas teoricamente relevantes, o valor acrescentado bruto, os resultados líquidos, os capitais próprios, a dimensão da empresa, a remuneração e as despesas em investigação e desenvolvimento (I&D). Os resultados do modelo estimado confirmam a influência positiva destas variáveis sobre a variação das exportações, embora as despesas em I&D e as remunerações se tenham revelado estatisticamente não significativas.

Corporate governance : value creation and performance in credit unions

In this study, we examine the relationship between good corporate governance practices and the creation of value/performance of credit unions from 2010 to 2012. The objective was to create and validate a corporate governance index for credit unions, and to then analyse the relationship between good governance practices and the creation of value/performance. The problem question is: do good corporate governance practices provide value creation for credit unions? The research started by creating indices from factor analysis to identify latent dependent variables related to value creation and performance; next indices were created from the principal component analysis for the creation of independent latent variables related to corporate governance. Finally, based on panel data from regression models, the influence of the variables and indices related to corporate governance on the indices of value creation and performance was verified. Based on the research, it became evident that the Corporate Governance Index (IGC) is mainly impacted by Executive Management, with 40.31% of the IGC value, followed by the Representation and Participation dimension, with 34.07% of the IGC value. The contribution for academics was the creation of the Corporate Governance Index (IGC) applied for credit unions. As for the contribution to the system of credit unions, the highlight was the effectiveness of the mechanisms for economic-financial and asset management adopted by BACEN, credit unions and OCEMG.
