The present paper aims to investigate the determinant factors of Portuguese merger control. Our sample comprises 652 M&A cases occurred between January of 2003 and September of 2015. Through a probit model we have tested the relevance of product and geographic market, entry barriers, type of concentration, merger effects, year of decision and the President of the Competition Authority at the time. The results suggests that the conglomerate and vertical effects, the existence of barriers to entry as well as the number of regulatory agencies listened are the main explanatory variables to determine a need for an in-depth investigation and to make a final decision. According to the evidence, cases cleared at Phase 1 are increasing over time. The number of prohibited mergers is close to zero.

AEIPS is a Portuguese social organization promoting the integration of people with mental health illnesses and/or substance abuse in the community through the intervention model Housing First. The philosophy of Housing First aims at lifting people out of their homelessness status by providing instant access to individualized and permanent housing as well as support services. Housing First projects from all over the world have proved very positive results in terms of residential stability and community integration of its participants. This feasibility study evaluates the suitability of using a Social Impact Bond to fund the Housing First intervention of AEIPS in Portugal.

Purpose – The purpose of this paper is to develop a subjective multidimensional measure of early career success during university-to-work transition. Design/methodology/approach – The construct of university-to-work success (UWS) was defined in terms of intrinsic and extrinsic career outcomes, and a three-stage study was conducted to create a new scale. Findings – A preliminary set of items was developed and tested by judges. Results showed the items had good content validity. Factor analyses indicated a four-factor structure and a second-order model with subscales to assess: career insertion and satisfaction, confidence in career future, income and financial independence, and adaptation to work. Third, the authors sought to confirm the hypothesized model examining the comparative fit of the scale and two alternative models. Results showed that fits for both the first- and second-order models were acceptable. Research limitations/implications – The proposed model has sound psychometric qualities, although the validated version of the scale was not able to incorporate all constructs envisaged by the initial theoretical model. Results indicated some direction for further refinement. Practical implications – The scale could be used as a tool for self-assessment or as an outcome measure to assess the efficacy of university-to-work programs in applied settings. Originality/value – This study provides a useful single measure to assess early career success during the university-to-work transition, and might facilitate testing of causal models which could help identify factors relevant for successful transition.

Para a grande maioria dos professores, tornarem-se melhores profissionais passa pelo alcance máximo de sucesso pelos seus alunos (Guskey, 2002), sendo este o principal foco deste relatório. A interligação entre as quatro áreas de intervenção do estágio pedagógico, permite potencializar cada uma. A reflexão sobre o desenvolvimento pessoal e profissional enquanto professora estagiária tendo em conta um sentimento de auto-eficácia positivo (Jardim & Onofre, 2009) e uma inteligência emocial (Mouton, Hansenne, Delcour & Coles, 2013) foi fundamental para contribuir para uma gestão correta da sala de aula através do modelo ecológico (Hastie e Siedentop, 1999) em conjunto com as 4 dimensões de uma intervenção pedagógico de sucesso (Sidentop, 1983; citado por Onofre, 1995). Tornando-se essencial entender a evolução e as diferenças entre os alunos por ser o centro do processo de ensino-aprendizagem. Assim, o trabalho do professor, começa muito antes do espaço de sala de aula (Fentermacher & Soltis, 1986). A comunidade escolar da Escola Secundária José Gomes Ferreira, compreende que a disciplina tem benefícios educacionais, mas nem sempre a consegue suportar. Assim, é necessário promover experiências positivas no 1º ciclo, de forma a desenvolver atitudes positivas face à Educação Física.

This study explores the perception of risk and the level of risk management implementation in the renewable sector. Risk management is emerging as a key issue due to the loss of confidence amongst banks, causing the attainment of financing to be difficult over the next few years. To attract financing, there is a fundamental requirement to manage risk in a way that minimizes the probability of a negative financial impact on the project. Miller and Lessard (2001) argue that successful projects are not selected but shaped with risk resolution in mind. Rather than evaluating projects at the outset based on projections of the full set of benefits, costs and risks over their lifetime, successful developers start with project ideas that have the potential of becoming viable. Therefore, this study bridges the gap that exists within the renewable sector in relation to risk management literature. This study succeeds through a detailed comparative case study analysis where two developers and two financiers were questioned through qualitative semi-structured interviews on the concept of risk management and its level implementation within the industry. It is believed that the growth in financed renewable energy projects depends on the adequate design and implementation of risk management to mitigate inherent project risks. However, this study revealed that are certain types of developers in existence within the renewable sector, which underestimate the magnitude of risk and view the development of projects as a ‘money racket’. Therefore, it can be concluded that perception of risk will also differ, causing risk and uncertainty to vary from project to project, resulting in investment reluctance to be associated with certain projects. The study originality lies in how it demonstrates to developers the concept of risk management, outlining the simplicity and benefits of implementing it in project development. Finally, this study contributes to the knowledge by enhancing the awareness and understanding of the presence and nature of risk in a RE project environment.

This paper analyzes the employment relationship on the basis of the notion of access. We argue that the degree of access provided by a job is an incentive to activate the employee’s self-actualization needs. We investigate the effect of access on the workers’ performance through an agency model and provide a number of propositions with practical implications for personnel policies. Our results are consistent with the intuition emerged from the real business practice as well as with many of the arguments on the substitutive role between monetary and non-monetary incentives frequently reported in the literature.

El consumo desmesurado de energía por parte de los países del Norte lleva a la creación de una deuda ecológica en los países del Sur. Ésta se debe, entre otros factores, al modelo agrario introducido con la “Nueva Revolución Verde”. En Argentina los monocultivos de sojaRR están potenciando la pérdida de la soberanía alimentaria en todo el país. Al mismo tiempo, las políticas energéticas europeas van a provocar una subida en la demanda de materias primas para la producción de biocombustible, lo que llevará a un aumento de la superficie de sojaRR en Argentina. El objetivo de este estudio es la creación de alternativas productivas mediante la implicación de la población de un municipio argentino. A través de la metodología de análisis social “CLIP” se han identificado los diferentes actores implicados en el modelo agrario que a lo largo del trabajo plantean propuestas de cambio para el sector agropecuario de su municipio. El resultado ha sido el planteamiento de cuatro grandes alternativas: la agricultura orgánica, la rotación de actividades, las producciones avícolas y apícolas y la diversificación de cultivos energéticos. Viendo que la tipología de consumo del Norte afecta directamente en la vida de los países del Sur, en todas las alternativas propuestas en este caso de estudio, se acaba por apostar por la creación de redes productivas y comerciales locales que potencien los beneficios en los países productores sin abandonar las posibilidades del mercado internacional.
