Kant vs Nash: Solving the Global Commons Goods Problem
Rocha de Sousa, Miguel; Duarte, VanessaWe provide the notion of Kantian equilibrium versus Nash equilibrium, a try to recover the efficiency of Pareto allocations within public goods (global commons) and external effects (like pollution). Nash (1950a,b) provided the first solution to a non zero-sum non-cooperative game through a fixed point theorem. Nevertheless, market efficiency is not recovered when there are either externalities (like pollution,...

Lições da Revolução Portuguesa dos Cravos de 1974 através de uma abordagem de T...
Rocha de Sousa, Miguel; Duarte, VanessaO objetivo deste artigo é revisitar a Revolução dos Cravos de 25 de abril de 1974 ocorrida em Portugal, celebrando assim o seu 47º aniversário. Esta revolução conduziu à obtenção de um governo livre e, portanto, à democracia pura, terminando com 48 anos de governo autocrático em Portugal, e permitiu que Portugal entrasse numa transição rápida para a Europa, para a democracia, para a descolonização e para as for...
Quantitative carcass characteristics and quality of shoulder and loin of crossb...
Pili, Fernanda Maraquena Soares; Schneider, Cibele Regina; Silva, Caroline Isabela da; Oliveira, Giovana da Silva; Altero, Jennifer BragaThe objective of this study was to evaluate the influence of live yeast (Saccharomyces cerevisiae var. boulardii) on the quantitative and qualitative characteristics of the shoulder and loin of Boer x Saanen crossbred goat kids. Twenty-seven carcasses were used, 13 females and 14 uncastrated males with an average age of 192 days, weighing 30.76 kg, distributed in a completely randomised design using a 2 x 2 fac...
Processes of pedagogical differentiation: perspectives of the students of the i...
Duarte, Vanessa; Figueira, ConceiçãoDealing with the diversity of students in today's classrooms is a challenge teachers face. Indeed, to believe that equal teaching for all can be advantageous is an illusion. It is precisely in this context that pedagogical differentiation appears as a response that allows the teacher to promote equal opportunities for all students. The study that we propose to present is developed within the scope of this probl...
Corporate Social Responsability and Sustainable Development in Brazil
Buainain, Antônio Márcio; Duarte, Vanessa; Rocha de Sousa, MiguelThis paper deals with the vast field of Corporate Social Responsibility (CSR), specifically applied to the case of Brazil, an emerging and important country in the world economy, specifically as the leading engine in Latin America. We start from the institutional framework that led and fostered CSR in Brazil, approaching the case of ISE-the innovative index of social responsibility in BOVESPA, then we cross exa...
Circularly polarized microstrip antenna array for the Ka-band
Varum, Tiago; Matos, Joao; Duarte, Vanessa; Pinho, PedroThe growing needs of higher transmission rates lead to the use of the Ka frequency bands and multi-beam technology, in the satellite communications, allowing more coverage. This fact leads to the need for the use of directive antennas and beamforming techniques to achieve a precise control of radiation pattern. This paper presents the design of a circularly polarized microstrip antenna array, at 29 GHz, suitabl...
Separating the wheat from the chaff - a taxonomy of open innovation
Duarte, Vanessa; Sarkar, SarkarPurpose – The main objective of this paper is to shed light on the confusion of terminologies related to open innovation through the development of an open innovation taxonomy. By analyzing published case studies using numerical taxonomy methods, it proposes a taxonomic classification of open innovation. Design/methodology/approach – Earlier work on firm collaboration and concepts related to open innovation in ...
Technology cycles, dominant design and firm survival in the early years of the ...
Duarte, Vanessa; Sarkar, Soumodip; Pires, CesaltinaThe history of western economic growth, especially North American, has been strongly influenced by farm mechanization. The dramatic increase in productivity which enabled the support of a hugely declining agricultural work force is due to a large extent to the arrival of motorization. In this, tractors, one of the most important components of a farm, have played a fundamental role. In this paper we identify a m...
Separating the wheat from the chaff – towards a taxonomy of open innovation
Duarte, Vanessa; Sarkar, SoumodipPurpose – The main objective of our work is to shed light on the confusion of terminologies related to open innovation through the development of an open innovation taxonomy. By analyzing published case studies using numerical taxonomy methods, we propose a taxonomic classification of open innovation. Design/methodology/approach – We first review earlier work on firm collaboration and concepts related to open i...
