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.     

Effects of perceived retail crowding: a meta-analytic study

ABSTRACT

We performed a meta-analysis to understand the crowding construct in the retail context. The systematic review identified 535 studies, of which 69 were present in the analysis conducted, generating 504 quantitative relationships. Our meta-analysis indicated that the perception of crowding generates many negative feelings, a few positive feelings, minimal perceived value, low attractiveness of the environment and low short- and long-term consequent behaviours. At the methodological level, it was found that student samples and experiments tend to produce a stronger impact on the relationship between crowding and satisfaction. It was also found that the effect of crowding perception on customer satisfaction differed according to cultural influence. Finally, the results did not demonstrate an influence of the type of density (human vs spatial) on the relationship between retail crowding and satisfaction.     

Dynamic relationships between crude oil prices and socially responsible investing in Brazil: evidence for linear and non-linear causality

Recent years have witnessed an increasing interest in socially responsible investing (SRI), reflecting investors’ growing awareness of social, environmental, ethical and corporate governance issues. At the same time, the effect of oil price shocks on stock price returns has become a prominent issue due to surges in energy prices. Using the Brazilian corporate sustainability index (ISE) as a benchmark for socially responsible investments in the Brazilian stock market, the present study extends the understandings on the impact of oil prices on stock price behaviour, focusing on a new class of assets: those from socially responsible firms. To this end, apart from conventional linear causality approaches, we apply a nonparametric test by Diks and Panchenko (DP) on daily data spanning from January 2008 to December 2015 to test for non-linear causality, before and after controlling for conditional heteroscedasticity. Our findings show that, in spite of their efforts to become more socially responsible, firms that have adhered to the ISE in recent years are influenced by crude oil spot prices, especially the WTI crude. In line with previous studies, we also provide consistent evidence that the Brazilian stock market, as a whole, is associated with the international crude oil market.     

A Socio-technical Approach for Group Decision Support in Public Strategic Planning: The Pernambuco PPA Case

This article describes a socio-technical approach to public strategic planning. A multi-methodological framework with decision support systems (DSS) of problem structuring, multi-criteria decision analysis and strategic thinking was used in a decision conferencing process to support the key-players of the Pernambuco State Department of Social Development and Human Rights, in Brazil, to elaborate its 2008–2011 Multi-Annual Plan (PPA). This interactive process took place in June 2007, with thirty technical and political actors meeting in 5 consecutive days to discuss what should be the fundamental objectives/development axes of the PPA and to generate, assess and classify intervention programmes to achieve the objectives. Structuring objectives and programmes started by a group causal mapping session supported by the Decision Explorer DSS. Then, a multi-criteria group value model, created on-the-spot by means of the M-MACBETH DSS, helped the politicians in evaluating the overall benefit of each programme. The doability of the programmes was also appraised with MACBETH and, finally, the programmes were classified into four benefit versus doability categories defined in a $2\times 2$ strategic graph: “pearls” (programmes with high benefit value and easy to implement), “oysters” (high benefit but difficult to implement), “bread and butter” (easy to implement but of low added value) and “white elephants” (low benefit and difficult to implement). The group agreed that at least all pearls and oysters should be selected. The programmes were prioritised based on their value-for-effort and the robustness of the selection was analysed with the PROBE DSS a posteriori.     

Coaches’ migration: a qualitative analysis of recruitment,motivations and experiences

This study examines sport coaches’ perceptions about their experiences abroad. Coaches are part of a diverse new set of mobilities occurring in the sport labour market. However, few authors explored the individual cases of coaches’ migration. Here, we examine coaches’ recruitment process, motivations to migrate and their experiences abroad. Participants were five migrant coaches chosen through purposive sampling to achieve a pool of deep and rich data regarding the research topic. Data was collected using semi-structured interview questionnaires. For the exploration and analysis of the qualitative data, we used MAXQDA 11 software package. The results showed that all coaches migrated through an informal mechanism of recruitment which relied on their networks. Their discourse suggested they fit three types of migration referred in the literature: ambitionist, cosmopolitan and pioneer. Their experiences abroad were mainly related to their professional career and adaptation. All coaches reported that their experience was positive and they recommend that other coaches migrate as well. These results are important for the understanding of sport migration not least because coaches are at the core of the migration process of various stakeholders.     

Conservation agriculture practices adopted in southern Brazil

The adoption of conservation agriculture (CA) practices are essential for soil and water conservation. In CA, farmers must adopt no-tillage (NT) with crop rotation to maintain a permanent soil cover. In Brazil, mainly in the South region, for CA to be more efficient, practices such as contour farming and agricultural terraces should also be adopted. Thus, the objective of this study is to determine the extent to which NT has been adopted with crop rotation and others soil and water conservation practices. Data from the Agricultural Census in Paraná State, southern Brazil, were used. For the data analysis, the relationship between the level of adoption of NT and the use of crop rotation, contour farming and agricultural terraces was analyzed. A factor and cluster analysis were performed to distinguish regions in terms of soil and water conservation practices. The results show good overall soil and water conservation practices, although heterogeneity has been observed in the adoption practices between regions. Adoption of NT is high in almost all the studied regions. The conservation practice most widely used with NT is contour farming, whereas the least used is agricultural terraces. Conservation practices for runoff control are being neglected by farmers.     

Re-scaling risk governance using local appraisal and community involvement

This paper describes a risk governance model applied on a local scale, showing the advantages and constraints found during its application. The risk governance model, built on a municipal scale, results from the application of the International Risk Governance Council framework. The model is characterised by the cyclicity between the assessment and management spheres, assuming communication to be essential in all stages. Its application in central Portugal is rooted in a specific knowledge of hazards and their impacts, the human and financial constraints, and the expectations of citizens and stakeholders. The results show that preformatted management solutions derived from national civil protection stakeholders can be adapted to a local physical, social and institutional context. It was found that this depends significantly on the stakeholders’ concerns assessment, as this allows the subsequent risk management options to be adapted and legitimised. As a result, more appropriate land-use regulations and mitigation strategies are being designed, which are related to urban planning, road design, risk sensitisation and communication tools. However, two features are likely to lead to an overlapping of competences and conflicts concerning responsibility for decision-making in the actual civil protection structure: the current constraints on resources on an operational level and the potentially inadequate representation of stakeholders on a strategic level.     

Monetary policy and country risk

This article develops an econometric model in order to study country risk behaviour for six emerging economies (Argentina, Mexico, Russia, Thailand, Korea and Indonesia), by expanding the country beta risk model of Harvey and Zhou (1993 Harvey, CR and Zhou, G. 1993. International asset pricing with alternative distributional specifications. Journal of Empirical Finance, 1: 107–31. [Crossref] , [Google Scholar]), Erb et al . (1996a, b) and Gangemi et al . (2000). Towards this end, we have analysed the impact of macroeconomic variables, especially monetary policy, upon country risk, by way of a time-varying parameter approach. The results indicate an unstable effect of monetary policy upon country risk in periods of crisis. However, this effect is stable in other periods, and the Favero–Giavazzi effect is not verified for all economies, with an opposite effect being observed in many cases.     

Gini playing soccer

The level of income inequality in a European country influences the competitive balance of its major soccer leagues. We test this hypothesis using cointegration techniques for seven male professional soccer leagues (the Dutch, English, French, German, Italian, Spanish and Ukrainian soccer leagues) from the 1980/1981 season to the 2011/2012 season. Controlling for the level of income inequality using variables such as real GDP per capita, trade openness and the emigration rate, we conclude that income inequality (measured by the Gini index) causes changes in the measures of competitive balance that we employ (the Hirschman–Herfindahl index and the SD) concerning the final number of points scored by the various teams.
