Abstract
Social entrepreneurship is emerging as an innovative approach for dealing with complex social and environmental needs, and is an important lever for the development of a sustainable society. Social entrepreneurship and related concepts have had a growing attention in the academy, giving rise to dissimilar approaches in the United States of America and in Western Europe. Despite the importance of the Third Sector in Portugal, it has been difficult to set ideal definitions for social entrepreneurship, social entrepreneur and social enterprises. By means of a qualitative study involving four Portuguese social ventures, this chapter identifies contemporary socio-cultural and economic factors that foster social innovation and intervention in Portugal, and contributes to understand the role of social entrepreneur in this context.

Abstract
This chapter analyzes the retail banking behavior in Portugal for the period between 2008 and 2010. The data collection took place through the accounting consultation of the reports and accounts of the years under analysis. The selected variables reflect the strategic actions of retail banking during the period under analysis, and it can be argued that retail banking in Portugal has clear differences among players over time. In particular, banking institutions have different competitive strategies, the strategic groups do not have similar resources, and strategies also differ between strategic groups. This reflects the competitive structure of the national retail banking industry.

Abstract
Purpose The existing literature suggests that multinational corporations (MNCs) divest subsidiary units whenever they cease to enjoy the advantages of ownership, location or internalization. However, not all MNCs divest under these conditions. This paper aims to explore the factors that contributed to the survival of a particular subsidiary and prevented it from being divested. Design/methodology/approach The analysis focuses on an individual subsidiary of a large foreign MNC in the electronics industry, which divested other subsidiaries from Portugal. Data were collected using semi-structured interviews. Findings The subsidiary's diverse customer base, specificity and high level of efficiency, the local advantages, the existing governmental agreements and the parent MNC's previous unsuccessful relocation experiences seem to have contributed to the survival of the subsidiary. Research limitations/implications - Although the results of the case study are not generalizable to the entire population of firms, the featured case study is a rare survival success story in the Portuguese electronics industry. Practical implications - The proposed framework may offer public authorities measures to create conditions to encourage firms to retain their investment in a particular site. For corporate strategists, new perspectives on subsidiary survival are provided. Originality/value This paper is one of the few qualitative studies in the field of subsidiary survival. The results offer an integrative framework on which factors contribute to the survival of a subsidiary located on a comparatively unfavorable labor cost location and support the role of the organizational learning and of previous failed relocation experiences and relocation barriers when a parent MNC decides whether to retain a unit.

Abstract
Purpose The purpose of this paper is to review the existing research on industrial divestment in order to identify the reasons for it, the process whereby it is achieved, and the outcomes of industrial sell-offs and closures. The study reports the main findings that have gained acceptance in the literature, gaps in the research and potential directions for future research. Design/methodology/approach A three stage systematic literature review protocol was used to conduct this review. The results are organized according to an "Antecedents - Process - Outcomes" framework. Findings The traditional accounts of industrial divestment have been framed in terms of firms' weak performance and over-diversification as antecedents to divestment, leading to corporate governance issues. However, the list of antecedents of industrial divestment is more extensive. There is no consensus over the impact of some factors on divestments, as is the case of firm and unit size. The results are not conclusive as to whether firm performance improves after divesting. Originality/value This paper synthesizes knowledge of the main reasons as to why firms completely dispose of their assets, contributing to this under-researched field.

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.
