Civil aviation has a longstanding tradition of investigating accidents and reporting incidents, which contributes to making aviation one of the safest forms of transport.To make flying safer, independent investigation into accidents is essential as it the surest way of identifying the causes of an accident and answering the fundamental questions “What really happened?” and “What can be done to prevent similar incidents in the future?”.The obligation to investigate accidents is enshrined in the Chicago Convention of 1944. Recognizing the importance of accident investigation, the European Union adopted Council Directive 94/56/EC establishing the fundamental principles governing the investigation of civil aviation accidents and incidents and later on Directive 2003/42/EC on occurrence reporting. They both significantly contributed to harmonization of accident prevention.But with air traffic steadily increasing, accidents do happen despite the best efforts of regulators and industry. The organization of the air transport sector is much more complex now than it was a decade ago. Today there is significant divergence in the investigating capacity of the EU Member States compared to 1994. Furthermore nowadays investigating air accidents take new kinds of expertise and more resources than a decade ago. At the same time there is a new legal and institutional environment in Europe derived from the adoption of European aviation safety rules. Also the organizational set-up has changed substantially with the establishment of the European Aviation Safety Agency (EASA), which is now responsible for certifying aircraft in the EU. The EU rules on investigating air accidents need to be updated to reflect the current realities of Europe's aviation market and the complexity of the global aviation industry.Accordingly, over the last few years the European Commission has been working on a Regulation on the investigation and prevention of accidents and incidents in civil aviation, with the intention of updating and replacing the existing Directive. With this new regulation the Commission aims to promote more efficient and independent inquiries into the causes of air accidents and also expects to strengthen the rights of the victims of air accidents.Today the end is in sight, once that the Commission and European Parliament have reached an agreement about the content and text of this new regulation. Reasons behind this new regulation are presented in this paper together with a detailed explanation of its main contents, an assessment of their impact and their expected benefits.  相似文献

The impact of past gains and losses on international investors' risk aversion is an important factor in the propagation of financial shocks across countries. We first present a stylized model illustrating how changes in investors' risk aversion affect portfolio decisions and stock prices. We then examine empirically the behavior of international mutual funds. When funds' returns are below average, they reduce their exposure to countries in which they were overweight and vice versa. An index of “financial interdependence” that reflects the extent to which countries share overexposed funds helps explain the pattern of stock market comovement across countries and the pattern of contagion during crises.  相似文献

Agenda-setting theory is used to investigate if consumers' online opinions on “greenwashed” advertisements (misleading green advertisements) are influenced by the agenda set by online newspaper articles and environmental nongovernmental organization (NGO) blogs. Leximancer is initially used to obtain attributes and identify themes from four different online stakeholder discussions on greenwashing. Content analysis and cross-lagged correlations are further used to verify if blogs and news articles set the substantive attribute salience in the consumer discussions over a 12-month period (January–December 2009). We found two significant themes in the various stakeholder discussions on greenwashing: marketing communication credibility and impact on natural environment. Results also indicate a bidirectional agenda-setting relationship between consumers and other stakeholders from the same country.  相似文献

The purpose of this study is to examine how workgroup diversity can be managed through specific strategic human resource management systems. Our review shows that ‘affirmative action’ and traditional ‘diversity management’ approaches have failed to simultaneously achieve business and social justice outcomes of diversity. As previous literature has shown, the benefits of diversity cannot be achieved with isolated interventions. To the contrary, a complete organizational culture change is required, in order to promote appreciation of individual differences. The paper contributes to this discussion by exploring the implications of this change for human resource management, and explaining how the systems of practices should be changed when they are directed to diverse groups. The model designed to test this notion includes: (1) demographic and human capital diversity as independent variables, (2) group performance (measured as innovation outcomes) as the dependent variable and, (3) the orientation of the strategic human resource management system as a potential moderator of this relationship. The main conclusion of the empirical analysis developed is that different patterns of human resource management practices can be used, depending on the type of diversity that the organization faces, and the specific effects that it wishes to manage. Concretely, three alternative management systems are identified in this paper, with different moderating effects. This result has interesting implications for human resource management professionals, explained in the last section. The limitations of this study are also discussed, as well as some issues that future research in this field should address.  相似文献

Job stress is an integral part of the organizational landscape and particularly severe in the sales profession. A host of studies have looked at felt stress, its antecedents, and consequences. This research examines how employee resistance to change and a manager's decisiveness affect the salesperson's felt stress and turnover intentions. This study shows that the salesperson's resistance to change is positively associated with felt stress. Study results also show that the impact of an employee's resistance to change on felt stress is moderated by a manager's decisiveness. Model hypotheses are tested with responses from 255 bank salespeople in India.  相似文献

A survey was conducted to investigate the relationship of Australian consumers’ lived (experienced) spiritual well-being and materialism with the various dimensions of consumer ethics. Spiritual well-being is composed of four domains—personal, communal, transcendental and environmental well-being. All four domains were examined in relation to the various dimensions of consumers’ ethical beliefs (active/illegal dimension, passive dimension, active/legal dimension, ‘no harm, no foul’ dimension and ‘doing good’/recycling dimension). The results indicated that lived communal well-being was negatively related to perceptions of the active/illegal dimension and the passive dimension and was positively related to perceptions of the ‘no harm, no foul’ dimension and the ‘doing good’/recycling dimension. Lived personal well-being was negatively related to perceptions of the active/illegal dimension and was positively related to perceptions of the ‘no harm, no foul’ dimension and the ‘doing good’/recycling dimension. Lived transcendental well-being was negatively related to perceptions of the passive dimension, the active/legal dimension and the ‘no harm, no foul’ dimension. Lived environmental well-being was negatively related to perceptions of the active/legal dimension and the ‘no harm, no foul’ dimension. The findings also indicated that materialism was positively associated with perceptions of actively benefiting from illegal actions, passively benefiting at the expense of the seller, actively benefiting from questionable but legal actions and benefiting from ‘no harm, no foul’ actions. Public policy implications of the findings and opportunities for future research are discussed.  相似文献

In this paper, we study the effect of labour market rigidity on the impact of exchange rate shocks on employment. We use a panel dataset comprising 22 manufacturing sectors across 23 OECD countries. In our econometric model, the impact of exchange rate fluctuations on sectoral employment is mediated by the degree of openness and by a measure of labour market rigidity: the OECD's employment protection legislation (EPL) index. Our results suggest that greater labour market rigidity reduces the impact of exchange rate shocks on employment. This effect is statistically significant for low‐technology sectors.  相似文献

Fear of missing out (FOMO) is an emerging topic in consumer psychology. However, the theoretical foundations of FOMO are underdeveloped and extant FOMO scales confine the construct to the context of social media. Without a theoretical foundation and a new FOMO scale, the future development of research on this promising phenomenon is limited. This article provides a new conceptualization of FOMO and a new FOMO scale. Using self-concept theory, the authors propose that FOMO is an emotional response to perceived psychological threats to one's self-concept. Because the self-concept involves a private and a public self, FOMO involves two dimensions: a personal FOMO and a social FOMO. Accordingly, a new scale was developed. The results of four studies support the validity and reliability of the two-dimensional scale. This new conceptualization and scale will enable consumer researchers to examine FOMO in a broader set of contexts, test the relationship between FOMO and related constructs, and develop a nomological network around the construct.  相似文献

In a context of increasing health problems related to bad dietary habits in developing countries, simplified nutritional label formats may be a promising policy alternative. The aim of this study is to assess whether the multiple traffic light (MTL) system can improve the nutritional quality of consumer decisions. We conducted a selection experiment in Peru, where participants were offered a choice between three alternatives in two different food categories (crackers and beverages). Individuals were randomly assigned products with MTL labels on them. Our results reveal that exposure to MTL labels significantly increases the probability of avoiding the least healthy options and of choosing the healthiest items among the alternatives provided. These effects are large in magnitude and seem to be driven by individuals that are female, report average or above average dietary habits, and lack basic nutritional knowledge. However, our findings also suggest that the effectiveness of MTL labels may be sensitive to the specific characteristics of the set of options provided. These findings contribute to the emerging experimental literature on MTL labels in two ways. First, we provide evidence that this system can be effective in inducing consumers to make healthier choices in real‐life situations. Second, we explore which individuals are more likely to benefit from exposure to MTL labels, as well as potential limitations to their effectiveness. Overall, our results provide new insights on how to assess the issue of bad nutrition in emerging economies.  相似文献
