- Financial instruments of forest policy in Portugal in the 80s and 90sPublication . Mendes, Américo M. S. Carvalho; Dias, Rafael A. R. da SilvaThis paper reviews the main programmes of financial incentives to forestry in Portugal through the 1980s and 1990s. First, these programmes are put in perspective with respect to the trends in forest resources and forest policy since the mid-19th century. Then, the main measures, beneficiaries and outputs are presented for each programme, together with an implementation analysis comparing the targets and outputs and giving plausible hypotheses to explain the implementation failures. The main conclusions of the paper are a long-term trend of increasing public financing to private forestry, with some remaining problems: unsustainable sources of public funds, and rates of afforestation and reafforestation still insufficient to make the forest industries competitive and to compensate for the damages caused each year by forest fires.
- Trust: theoretical framework, underlying disciplines, and measuresPublication . Cruz, Joaquin Garcia; Silva, Susana Costa eToday it is necessary to study trust considering the characteristics of the environment in which organizations operate. The relevance of the concept is more than justified, as much for the academic world as for the organizational practice. On one hand, the extant amount of literature shows its importance in the academic scope. And, on the other hand, since organizations are more and more concerned with replacing conflict management by the use of cooperative behaviours, trust becomes a key element. Trust is a multidisciplinary, heterogeneous and ambiguous construct. There is a lot of literature about it in different fields. Despite all research on trust to date, it so far impossible to reach an agreement concerning a consensual paradigm about conceptualisation, theoretical framework and underlying disciplines, levels of analysis, unit of analysis, generating factors and consequences. The purpose of this paper is to contribute to the understanding of trust, through a literature review and a content analysis about: theoretical framework according their purpose of study; conceptualisation, generating factors and consequences. The sources for this analysis are papers published at the three EURAM Conferences (2001, 2002 and 2003), as well as, the special issues on trust published by three prestigious journals, such as the Academy of Management Review (1998), Organization Studies (2001), and Organization Science (2003). These conferences and journals are taken as basis for this study as they have explicitly shown a particular interest in the understanding of the trust concept.

- Animals’ health control efficiency in Northwest Portugal: A two-stage DEA approach.Publication . Costa, Leonardo; Lansink, Alfons Oude; Silva, ElviraA two-stage approach is employed to analyze the efficiency of cooperatives responsible for ruminants’ disease control (OPP) at the farm level in Northwest Portugal. In the first stage, Data Envelopment Analysis (DEA) is used to estimate and decompose input-based overall inefficiency for each OPP. The input-based inefficiency measures are generated using the directional input distance function. In the second stage, the inefficiency estimates are regressed on environmental and organizational factors in order to explain efficiency differentials. Despite substantial environmental differences, the empirical results indicate that most cooperatives can reduce costs by improving scale efficiency and pure technical efficiency

- Student Performance in Mathematics in Portugal using PISA-2009 dataPublication . Susana, Faria; Portela, MariaThe Programme for International Student Assessment (PISA) is an international study launched by the Organisation for Economic Co-operation and Development (OECD) in 1997. It aims at evaluating education systems worldwide by assessing 15-year-olds' competencies in three key subjects (reading, mathematics and science) every three years. Studies based on PISA data to explain student performance are very common in literature. This paper is based on Portuguese data from PISA 2009, and it focus on the measurement of student achievement in mathematics and on the determinants of this achievement both at the student and at the school levels.
