Abstract
This paper seeks to analyse how behavioural factors influence the financial decisions of young Mozambican investors. The standard theory of finance assumes investors make rational financial decisions, seeking to minimise risk and maximise their expected utility. However, several studies have been conducted criticizing the assumption that investors are rational, opening the way to behavioural finance theory. According to the behavioural finance approach, financial decisions made by individuals are not based on rational thinking and their risk taking behaviour depends on their beliefs or feelings. Our analysis reveals that young Mozambicans are risk averse towards certain gains and risk lovers when faced with certain losses; they are excessively optimistic about the future; they use the information available as an anchor for their estimates; and they are so overconfident that they believe estimates in uncertain situations to be more accurate than they really are.

Abstract
Purpose - The purpose of this paper is to estimate retailing efficiency in a 26-store women clothing retail chain and to decompose it in several measures in order to contribute to the performance improvement of this retail service firm, as well as to compare the efficiency of the different decision making units. Design/methodology/approach - This paper uses the following measures to estimate efficiency: sigma convergence analysis; efficiency analysis; technical efficiency (TE) analysis; pure technical efficiency (PTE) analysis and scale efficiency (SE) analysis for a set of 26 stores of a women retail service brand operating in Portugal. A cross-section input-oriented data envelopment analysis (DEA) is used to analyse quarterly data sets from 2010 to 2013. Findings - The results show that costs with personnel are slightly increasing when analysed using the sigma convergence method, although there are some geographical differences. Moreover, it is possible to witness that the retail store chain's TE diminishes as the operations outputs do not grow as fast as input savings. On the other hand, there are no SE problems as the levels of SE are larger than pure efficiency levels. Research limitations/implications - The main limitation of the study stems from the fact that the analysis is based on a simple retail chain, which makes it a single case study. Therefore, the generalisation of the conclusions for other firms or for other periods of analysis should be made cautiously. Practical implications - It is shown that some stores have a good TE and other stores have some SE advantage. As such, it is possible to select some stores as benchmarks to deploy internal efficiency throughout the retail chain. Originality/value - The contribution of this paper is based on the application of the sigma conversion and DEA techniques to evaluate efficiency in retail service store.

Abstract
The direct relationship between national cultural practice and entrepreneurship activities is analyzed in this chapter, based on the analysis of 44 countries. Datasets from 2012 and 2013 Global Entrepreneurship Monitor (GEM) report are used to characterize three types of entrepreneurship: Early-Stage entrepreneurial activity (TEA); Necessity-Driven entrepreneurship (NDE) and Opportunity-Driven (ODE) entrepreneurship. Data sets on national cultural values are used to analyze five dimensions of Hofstede's work on cultural values (power distance, individualism/collectivism, masculinity/femininity, long/short term orientation, and uncertainty avoidance). For that, the authors use the Values Survey Module 2013, which has been adapted from Hofstede's previous work from 2010 and 2008. The main conclusion is that the three types of entrepreneurship analyzed in this chapter are differently explained by the cultural and expanded models. If the country of origin and the type of economy are useful to explain TEA, they are of no added value to explain Necessity-Driven or opportunity-driven entrepreneurship.

Abstract
This paper analyses the relationship among marginal costs per power plant, fossil fuel prices and electricity bidding quantities in the Spanish electricity market. The results of the panel cointegration and Granger causality methods clearly indicate a differential impact of fossil fuel prices on power plants marginal costs, with a positive effect for gas power plants. The biggest negative impact on marginal costs is seen for coal technology. As a consequence of the characteristics of different production technologies, the set of marginal costs across the sample is based on coal power plants, although Endesa and Iberdrola's marginal costs are predominantly based on gas power plants. Operating costs for hydroelectric power plants are very low when compared to the thermal power plants, which is the base technology used by Endesa, since this technology is strongly dependent on the volatility of commodity markets and on the supply chain and production costs management.

Abstract
This paper investigates if the existence of complex structures plays an important role in corporate governance. It uses GMM estimation on a panel of Western European firms. We find that the presence of a second and third large shareholder has a significant positive effect on firm value. This study underlines the importance of the number of blockholders as a determinant of firm value, when taken as a moderator of the contestability effect. It shows that the legal context and company-specific characteristics play a crucial moderating role for contestability. In contrast to previous research, we find that contestability plays a less relevant role in family firms. We also find that this last result does not vary significantly with the identity of the remaining elements of the coalition. Also, our study suggests that contestability is less important in companies led by majority shareholders.

Abstract
Due to today's business environment demands organizations need to create teams to perform work in projects, with quality, within time and budget. Therefore, teams play a very important role in the organizational development, by creating conditions that enable to overcome difficulties and to promote the improvement of the organizational overall performance. Hence the relevance of studying the project teams resilience, identifying the actions that can influence the project development and its final outcomes. The resilience of a team can be defined as the team's ability to deal with problems, overcome obstacles, or resist the pressure of adverse situations, without entering into rupture. This research, focused on team resilience, firstly involved a literature review, followed by brainstorming sessions, resulting in a preliminary list of useful actions to improve project team resilience. Then, a survey was administered in order to identify the most useful actions perceived from the identified list. Completed questionnaires were received from 115 team members of information technologies/information systems projects being developed in an academic setting. By identifying the most useful actions perceived, as those having the highest potential for increasing project team resilience, practitioners and organizations can set their priorities towards improving team resilience. The results showed that the top ten list of useful actions identified is composed by very well-known and recognized actions, such as the promotion of collaboration and solidarity among project team members, and the recognition, appreciation and use of the talents and competencies of each team member.
