Abstract
The objective of this work is to identify the relevant factors that have influenced the changes in the level of CO2 emissions among four groups (eastern, western, northern and southern) of European countries. Our results show that CO2 emissions are correlated with the energy consumption of the economy for the group of countries under analysis, which is determined by the change of population among the various countries. Similarly, renewable energy consumption is also determined by the size and structure of the countries, as reflected by the value added to the economy. When comparing the results of the post-Kyoto period to the previous period for the four groups of European countries, one concludes that there are clear improvements in the reductions of emissions. This resulted primarily from changes to the energy mix, switching to cleaner fuels for end-user energy production (a volte-face in the behaviour of the energy mix effect), while the changes in the factors driving emissions resulted from a reduction in the usage of fossil fuels for producing energy. In general, the relative contributions of these two factors show the importance of the impact of changing the structure of the mix for producing energy, with a view to complying with the targets for reductions in CO2 emissions, reflecting the value placed on the significant impact assigned to emissions levels.

Abstract
When compared to other fields of research such as mergers and acquisitions, corporate divestment is under researched. There are at least three main reasons for this: the environment in which corporate divestment research has taken place has caused divestments to be understood as acquisition-driven rather than strategy-driven, the scope and distinct modes of divestment, and the difficulties in isolating the divestment phenomena. The objective of this chapter is to review the main theoretical approaches used in the study of divestment, to analyze their contribution to the field, and to discuss whether new approaches are needed in divestment research. Most studies of divestment are based on the concept that divestment is the outcome of poor unit performance, and the reversal of previous over-diversification and growth strategies that expanded the company size beyond optimal control. This chapter proposes four future lines of research into corporate divestment: the international business strategy, the network perspective, the stakeholders' perspective, and the institutional theory.

Abstract
In previous work regarding public-private partnership (PPP) arrangements the theoretical rationales and empirical results have mainly focused on analyzing the importance of quantitative features related to budget constraints deriving from public deficits, the existence of an infrastructure gap and the efficiency hypothesis. Thus, this study aims to identify the underlying determinants behind the proliferation and execution of PPPs, emphasizing the importance that non-financial (such as political, legal and macroeconomic) determinants have in establishing a PPP, as well as the factors that enhance the attractiveness of a country to encourage the private sector through PPPs in the European context. The results of this study show that the macroeconomic environment represented by economic freedom, competitiveness and the unemployment rate is essential for PPPs, as well as the legal system, where regulatory quality and effective rule of law are associated with the effective execution of a PPP. The political environment and previous experience of PPPs are also key factors in making a country more attractive for establishing PPPs.

Abstract
The present paper seeks to address a gap in the literature regarding green marketing and examines the relationship between ecological concern, inward and outward environmental attitudes, purchasing behavior and environmental behavior as antecedents of green purchasing behavior. The data was gathered through an online survey carried out in Portugal with 530 valid answers. Structural Equation Modelling Partial Least Squares (SEM-PLS) was used to evaluate the model. A t-test was applied to identify differences between men and women. The results show that ecological concern, environmental attitude, environmental behavior and purchase intention are good predictors of green purchase behavior. Women scored higher than men on all variables, meaning that they are indeed superior environmentalists than men. Green purchase behavior is strongly influenced by both purchase intention and environmental behavior, so green brands should focus on targeting individuals that already take some actions in what concerns the environment, or to those who intend to do so.

Abstract
The aim of this paper is to analyse Brazil's tourism destination image taking into account travel agents and tour operators' perspectives. This paper thus seeks to complement previous research carried out based on travellers' viewpoints. This research, more specifically, sought to analyse the antecedents of Brazil's overall image from the perspective of Portuguese travel intermediaries. For that cognitive image, affective image and marketing communications were analysed as antecedents of Brazil's overall image, and visitation influence was modelled as a mediator. Based on a questionnaire completed by 132 Portuguese travel agents and tour operators, the results show that the total (direct and indirect) effect of both cognitive image and marketing communications are more important than the total effect of affective image. Moreover, the visitation influence exerts no mediation at all between affective image and overall destination image, although there is a mild partial mediation effect involving the other two antecedents (cognitive image and marketing communications).

Abstract
Innovation is recognised as an important source of competitive advantage by both academics and managers. Nowadays, supply chain partners play a crucial part in driving many aspects of innovation, from the definition of the product concept to the launch to the market. This chapter analyzes how the relationship between supply chain management and the innovation process is addressed in the literature and discuss ways to improve the performance by means of this relationship. A bibliometric analysis—including citation and co-citation analysis—is carried out to study the intellectual structure of the topic. In the end, four literature clusters were identified, and their characteristics are discussed. © 2018, Springer International Publishing AG, part of Springer Nature.
