In the first half of the nineteenth century, Nassau Senior and John Stuart Mill advanced two influential methodological accounts of 'classical' political economy, arguing for a distinction between the 'science' and the 'art' of political economy, and thus heralding the positive/normative divide that would become pervasive in economics. At the time, these views aroused controversy. In this paper two critical perspectives are examined: Friedrich List's and John Ruskin's. List tried to build his approach to political economy upon a 'middle ground' between 'theory' and 'practice', openly integrating the political element in economic discourse. Ruskin strongly objected to the possibility and the significance of the art/science split, since he maintained that political economy must be explicitly prescriptive and grounded on articulated value choices. By recalling the terms of nineteenth-century controversies, this paper seeks to draw some implications for contemporary debates. ; FCT

With the recent Clinical Trials Directive, a degree of harmonisation into research ethics committees (RECs) across Europe, including the time taken to assess a trial proposal and the kinds of issues a committee should take into account, has been introduced by the European Union (EU). How four different member states—Hungary, Portugal, Sweden and the UK—have chosen to implement the directive is shown. Although this has resulted in four very different ways of structuring RECs, similar themes are present in all four cases, such as centralisation of control over RECs within member states, harmonisation of REC procedures across the EU and increased role of political decision making with regard to such committees.

Economics and social psychology come from different traditions in social science, and in the past they seldom met. Their territories seemed to be well delimited. The former discipline's mainstream focused on market mediated interactions, making sense of an asocial concept of action by referring it to "the ordinary business of life" (Marshall, 1920, I.II.1) where agent's choices supposedly are independent from those of other parties in the transactions (Sugden, 2002); on the other hand, the second discipline descends from the more romantic view of man as a social being, and was stimulated by questions on why and how the immersion of individuals in the multitude, or the simple presence of others, appeared to transform behaviour. Lately, however, economics has started moving in a direction that reduces this gap. In a double but interrelated move, economics is adopting experimental methods familiar to those of social psychology, and is becoming more concerned with the relevance of rational choice in contexts where there is clear inter-individual dependence, raising questions to which social psychologists have already devoted considerable time and effort. As a part of this movement, social dilemmas, that is, "situations in which (a) individual group members can obtain higher outcomes (at least under some circumstances) if they pursue their individual interest while (b) the group obtains higher incomes if all group members further the group interest" (Dijk and Wilke, 1998: 110) have become the focus of shared interest of both economists and social psychologists. The motivation for the study of social dilemmas does not differ much in economics and social psychology and it arises out of two major types of challenges. The first (Fontaine, 2002) is related to the growing consciousness of the pervasiveness of market failures (combined with government failures) concerning issues of major social urgency like pollution and the use of scarce resources. The second, (Dawes, 1991) cropped up out of the finding that people both in real-life and experimental contexts fail to behave systematically in the way depicted by standard game theory, often opting for more benign strategies. Interest in social dilemmas is thus related, on the one hand, with the concern with problems that the market cannot solve, and, on the other, with understanding the reasons that may drive people to act in ways that are not in line with rational self-interest. For economics those questions are arcane questions 1 that were never ignored by the best minds in this discipline. Marshall's sentence in epigraph is a clear instance of this concern. This essay does not intend to cover the whole scope of existing approaches to social dilemmas since it only deals with dilemma situations that somehow fit into the economist's category of public good provision problems and with the experimental studies in economics and social psychology2. On the basis of an exploratory joint survey of experimental literature from both disciplines, it focuses on their differences in theoretical framing and their use of the experimental method. The following points will be argued: (a) Twenty five years of experimental research in both disciplines have produced an impressive accumulation of coherent results showing that in spite of the free-riding prediction, there is a tendency to voluntary contribution in "small" groups; (b) Notwithstanding the abundance of experimental studies, several interesting problems remain unexplored. In economics, the research focus has been on "are the game theoretical predictions corroborated by experimental evidence?", whereas in social psychology it has been on "what may cause the voluntary disposition to contribute". Questions pertaining to "what institutional contexts might hinder or foster voluntary contribution" still offer a vast domain of unexplored possibilities. (c) In spite of all efforts, the conceptual framework that may account for the contributive disposition in public good dilemma situations and help "discover how this latent social asset can be developed" remains rather sketchy.

O presente artigo providencia uma análise das noções de prática política e espaço público tendo como referência os principais entendimentos da Filosofia Política de Hannah Arendt. O primeiro ponto deste estudo é compreender a política em suas inter-relações conceituais com o mundo comum e com o "direito a ter direito". No segundo momento discutiremos as definições arendtianas da ação e do discurso destacando como elas são importantes para o estimulo a uma verdadeira prática política dialógica, com ampla participação dos agentes. Esta análise nos permite indicar que práticas políticas dissociadas de uma efetiva participação popular discursiva não são capazes de satisfazerem as necessidades de uma sociedade civil e nem tampouco de um Estado de Direito.

AbstractPrioritizing information technology (IT) projects for resource direction is a complex decision‐making process that involves the analysis of qualitative and subjective criteria. The uncertainty of the subjective and imprecise assessments derived from estimated data that represent the analyzed criteria characterizes the decision‐making process. To reduce the uncertainties related to IT project priority setting, we proposed a model based on a hybrid multicriteria method composed by the best–worst method to establish the weights of the criteria and fuzzy‐TOPSIS to define the project ranking. The model allows us (1) to define strategic subcriteria, (2) adjust the weights according to the company's reality, (3) to deal with the uncertainties of the evaluations of the decision makers, and (4) provide the project ranking that translates reality into the distribution of resources in the IT sector. Finally, we applied the model to a case study in the IT sector of a Brazilian agroindustrial cooperative. For the managers, the method provides a precise decision aiding tool. Although the model has been applied to the prioritization of IT projects in a cooperative, the same can be generalized to the IT sectors of other companies.
