Victims of road accidents with serious injuries and dependence on some individual,climatic and infrastructure factors on federal highways in Brazil

Abstract

Road or urban traffic accidents in Brazil have a large presence in external causes of mortality. The main goal of this study is to discover significant factors in the incidence of accidents on Brazilian highways based on a database with information on each person injured on federal highways in Brazil reported by the Federal Highway Police. Some factors are considered in the study as cause of the accident, type of accident, stage of the day, weather condition, highway type, highway facility, age of the victim, gender of the victim and type of vehicle. From the obtained results of chi-square tests and logistic regression models, it was observed statistical dependence (p?<?0.05) of the occurrence of injured people with serious injuries and the factors cause of the accident, type of accident, day, highway type and vehicle type. Considering the dead victims, the covariates age, time of day, highway type, highway facility, gender and type of vehicle showed significance (p?<?0.05). These results are of great interest for authorities to increase road enforcement, improve highway facilities and target the production of vehicles with better safety standards.     

Aiding Car Producers in the EU: Money in Search of a Strategy

This article investigates how the general principles of the Treaty have been applied to the car sector in the EU, where the soft law provisions are of particular interest. A detailed quantitative analysis from 1990 to 2008 highlights a reduction of aid over time. A shift from sectoral to “regional development” motives in granting aid to the sector is also observed in the last 10 years. However, sector specific aid is now less explicit but it remains important. Large amounts of public money are spent without a consistent strategy, reducing capacity in some cases, expanding it in others. The scarcity of public funds calls for a more focussed European policy for this industry.     

Joining the pack or going solo? A dynamic theory of new firm positioning

The question of new firm positioning in the marketplace and entrant's subsequent long-term performance lies at the heart of strategic entrepreneurship. We suggest a dynamic theory of new firm positioning that hinges on an important feature of the competitive environment: industry-level product diversity. The key argument is that industry-level product diversity drives imitation or differentiation at entry, which in turn shapes the exit likelihood of new entrants. So, in our theory, the extent of the new entrant's product portfolio overlap with all the industry's incumbents takes center stage. Support for our logic is obtained from the analysis of the life histories of 640 British motorcycle producers during the period 1899–1993.     

Fiscal Decentralization and Economic Integration in Mercosur: Argentina and Brazil

ABSTRACT

This article examines the relationship between economic integration and fiscal decentralization for Argentina and Brazil. Economic openness adds costs and benefits to fiscal decentralization, beyond those analyzed in closed economies. The relationships among variables with panel data for the period 1988–2005 are estimated. The innovation of the article lies in considering decentralization at the level of states/provinces. In Brazil, the effect of openness on decentralization is negative and significant, both for expenditures and revenues; in Argentina, the effect is negative or not significant. This difference between countries is based on the different structure of subnational government financing.     

Factor Substitution, Average Firm Size and Economic Growth

This paper extends the Lucas (1978, The Bell Journal of Economics 9(2), 508–523) analysis of firm size by taking into account a normalised aggregate CES production function. In a general equilibrium framework it is proved that there is an inverse relation between the elasticity of substitution and average firm size. If interpreted together with the fact that richer countries are characterised by a higher elasticity of substitution, this result can explain why the recent literature finds a positive association between the importance of SMEs in an economy and its stage of development, but seems to fail in finding causality between the two. Both have a common origin: a high value of the elasticity of substitution. This paper also provides a first empirical test of the theory proposed using cross-country data from both developed and developing countries.     

Uncovering Unobserved Economy: A General Equilibrium Characterization

This paper builds a three‐sector DSGE (Dynamic Stochastic General Equilibrium) model, considering explicitly the interactions among regular, underground and criminal sectors. We generated quarterly data for unobserved variables for Italian economy over the sample 1974:01–2011:02, through Monte Carlo simulations, and we found that underground economy is about 20 per cent of GDP, whereas criminal economy is 11 per cent. The dynamic behavior of the model shows that (1) regular production has a greater relative volatility with respect to unobserved production, (2) an efficient law enforcement activity is able to weaken unobserved activities and (3) unobserved sectors' variables exhibit a negative correlation with the corresponding ones of regular economy.     

Competitive channel relationship management: When resellers establish competing manufacturer relationships

The focus of this study is the impact of competitive relationships on the effectiveness of channel relationship management strategies. We argue that the characteristics of a reseller??s relationship with alternative manufacturers influence his/her evaluation of the relationship with a focal manufacturer. We extend previous research by suggesting that the relative levels of channel conflict and information exchange are critical determinants of relationship outcomes. Building on previous literature on customer satisfaction, we argue that this relation is asymmetric; improvements in the levels of channel conflict and information exchange will have a greater effect when these are below the competitor??s comparative level than when these are above. We find support for these hypotheses in a sample of 491 observations corresponding to different resellers selling a manufacturer??s product line across several countries. Our results underscore the need for suppliers to go beyond conflict minimization and information exchange policies across relationships and consider individual-level competitive effects for each relationship.     

Facilitating Collaboration with Problem Structuring Methods: A Case Study of an Inter-Organisational Construction Partnership

Despite the potential of inter-organisational collaboration to create ‘collaborative advantage’ among participant organisations, not all collaborations realise this potential due to the complexities and challenges faced by potential collaborators. To address these difficulties and increase the likelihood of collaborative success, different forms of intervention approaches for fostering inter-organisational collaboration has been advocated by collaboration researchers and practitioners. These intervention approaches all facilitate interaction and consensus formation among the participants. However their ‘added value’ is procedural rather than substantive in nature. They do not incorporate tools which can enable participants to structure the complexity of the web of factors that are implicated in their collaboration, and thus make it more manageable. This paper argues that problem structuring methods (PSMs), a family of model-based approaches to group decision and negotiation support, are a form of intervention which can provide a balanced attention to both the process and the content of inter-organisational collaboration, and reports the experience of applying a particular PSM to an inter-organisational collaborative partnership in the UK construction industry. Drawing on the rich data generated from the intervention, the paper discusses the impact of the PSM in supporting the joint appreciation activities carried out by collaborators to address their problematic situation. Implications of the experience for the research and practice of PSMs within collaborative contexts are then presented.     

GSS for Multi-Organizational Collaboration: Reflections on Process and Content

Multi-organizational collaboration has become the norm for modern organizations as they seek to survive and prosper in increasingly turbulent times. These collaborations can take many forms, but face problems due to different management styles, different cultures, and different operating modes of the participant organizations. These differences usually cause difficulties for the multi-organizational teams that are set up to make the collaboration operational. Group Support Systems (GSSs) is one possible way of supporting these multi-organization collaboration teams (MCTs). This paper builds and describes a conceptual framework that highlights the critical characteristics of these teams and how GSS might support their activities. The framework is based on a detailed analysis of three case studies using three different GSSs.
