Moderação da orientação de valor social entre ativação da identidade e eficácia de incentivo em grupo: um estudo experimental baseado em jogo de bem público / Moderating guidance of social value between activation of identity and effectiveness of group incentive: an experimental study based on game of public good.

Díeng, Mamadou 30 May 2016 (has links)
O free-riding (trapaça) e a coordenação são dois tipos de problemas potenciais em contratos de incentivo em grupo, especificamente, em contratos de incentivo baseado em meta orçamentária de grupo. A orientação de valor social (SVO - Social Value Orientation), medida de diferença individual que classifica as pessoas em individualistas - maximizadores do interesse próprio, competidores - maximizadores da vantagem relativa, e pró-sociais - maximizadores do resultado do grupo -, é fator importante que tem implicações no desenho dos contratos de incentivo em grupo. O estudo de Upton (2009) revelou que, com base na orientação de valor social dos indivíduos, os indivíduos de orientação pró-social apresentam maior desempenho e menor probabilidade de trapacear sobre as contribuições dos membros do grupo do que os indivíduos de orientação individualista e competidora. Além disso, para as empresas que adotam este tipo de contrato para o fornecimento de incentivo em grupo, a seleção de trabalhadores com preferência do tipo pró-social seria mais adequada para assegurar a produtividade do trabalho em grupo, e assim melhorar o desempenho empresarial. Nesse contexto, este trabalho busca mostrar que embora a SVO seja uma importante consideração para o desenho do contrato, outro fator tal como a identidade do grupo é também um elemento a ser incorporado neste processo, uma vez que um dos grandes desafios para resolver os problemas de uma situação de dilema social, como a do contexto de incentivo em grupo, é promover o comportamento cooperativo em ambiente de produção em grupo. Portanto, manipulações baseadas na ativação da identidade, processo pelo qual os indivíduos manifestam suas preferências em recompensas individuais ou do grupo, poderiam ter influência no desempenho de grupos com diferentes tipos de SVO. O presente estudo teve como objetivo investigar o papel moderador da ativação da identidade no efeito da SVO sobre o desempenho de grupo em contrato de incentivo baseado em meta orçamentária de grupo. Em um experimento, 135 estudantes de curso de graduação de quatro (4) Instituições de Ensino Superior do Estado da Paraíba realizaram um jogo repetido de dilema de bem público nas condições experimentais de identidade pessoal e identidade de grupo. Os resultados indicaram significância estatística do efeito principal da identidade no desempenho de grupo, enquanto a SVO não teve efeito significativo. Encontraram-se evidências de moderação da SVO no efeito da ativação da identidade de grupo nos grupos de participantes com SVO individualista e competidor, confirmando assim a hipótese de transformação de motivos. Porém, nenhum efeito foi observado nos grupos de participantes com SVO pró-social, refutando desta forma a hipótese de ampliação de motivos. / Free-riding and coordination are two types of potential problems in group incentive contracts, specifically in incentive contracts based on budget target group. The social value orientation (SVO - Social Value Orientation), individual difference measure that classifies people in individualistic - maximizers of self-interest, competitors - maximizing the relative advantage, and prosocial - maximizing the outcome of the group -, is an important fator which has implications for the design of group incentive contracts. Upton (2009) revealed that based on the social value orientation of individuals, pro-social value orientation of individuals have higher performance and less likely to free-ride on the contributions of members of the group than individuals having individualistic value orientation and competitor. In addition, for companies that adopt this type of contract for the supply of incentive group, the selection of workers prefer the pro-social type would be best suited to ensure the group in labor productivity, and improving business performance. In this context, this thesis seeks to show that while the SVO is an important consideration for the contract design, other factors such as group identity is also an element to be incorporated in this process, since one of the major challenges to solve the problems of a social dilemma situation as the group incentive context, is to promote cooperative behavior in group production environment. Therefore, manipulations based on the activation of identity, the process by which individuals manifest their individual preferences rewards or group could have an influence on the performance of groups with different types of SVO. This study aimed to investigate the moderating role of identity activation in the effect of the SVO on the group of performance incentive contract based on budgetary target group. In one experiment, 135 students of undergraduate course of four higher education institutions of the Paraíba State conducted a repeated game of public good dilemma in the experimental conditions of personal identity and group identity. The results showed statistically significant main effect of identity in the group of performance, while the SVO had no significant effect. They have found evidence of moderation in SVO effect of group identity activation in groups of participants with SVO individualistic and competitive, thus confirming the hypothesis of transformation motives. However, no effect was observed in groups of participants with pro-social SVO, thereby disproving hypothesis amplification motives.

Analyse du comportement coopératif pour une consommation durable des ménages : une approche expérimentale / Analysis of cooperative behavior for sustainable household consumption : an experimental approach

Groff, Jocelyn 06 April 2018 (has links)
La thèse porte sur les comportements de consommation durable des ménages. Lorsque les comportements de consommation permettent de retirer une utilité individuelle, au détriment de l’intérêt général, ils peuvent être analysés comme un dilemme social. Les expériences de jeu de bien public permettent de tester des comportements en situation de dilemme social. Consommer de manière durable peut être considéré comme une contribution volontaire à un bien public. La problématique est de mieux comprendre les mécanismes de contribution volontaire à des biens collectifs qui génèrent des externalités. Trois expériences nous permettent d’analyser les différences de contributions entre un bien privé et des biens publics, mal(s) publics et biens clubs. Plus particulièrement, nous nous intéressons aux externalités négatives d’un mal public, à l’exclusivité du bien club et aux effets de la présence de biens collectifs multiples. / This thesis focuses on the sustainable consumer behaviour of households. When consumer behaviours allow for individual utility, at the expense of public interest, these can be analysed as a social dilemma. Experiments in public good games allow for testing behaviours of individuals subjected to social dilemma situations. Sustainable consumption can be considered as a voluntary contribution to a public good. The objective is to better understand the mechanisms behind voluntary contributions to public goods that generate externalities. Three experiments will allow us to analyse the differences in contributions between a private good and public goods, public bad(s) and club goods. We focus on the negative externalities of a public bad, the exclusivity of the club good and the effects of multiple public goods.

Concessão florestal: exploração sustentável de florestas públicas por particular / Forest concession: sustainable exploration of public forest by the individual.

Raul Miguel Freitas de Oliveira 19 May 2010 (has links)
Esta tese tem por objeto a análise da concessão florestal, instrumento de outorga do uso de florestas públicas em caráter privativo ao particular. Por tratar-se de uma relação jurídica, a análise é detida nos seus elementos componentes, que são basicamente o objeto, partes e regramento jurídico específico, comparando-a com outras espécies de concessão, como a concessão de serviço público e a concessão de uso de bem público. Iniciando-se pelo estudo da tutela jurídica da floresta, uma vez que a concessão florestal também é instrumento de sua proteção, perpassa-se pelo delineamento da concessão e modelos de gestão de florestas públicas em outros países, para se alcançar o ponto principal que é a análise das regras da Lei nº 11.284, de 02 de março de 2006, marco regulatório da gestão de florestas públicas brasileiras. A conclusão procura realçar, dentre outros aspectos, a existência de uma efetiva política pública de gestão das florestas sob o domínio do poder público, erigida sobre o princípio constitucional do desenvolvimento sustentável do meio ambiente. / This thesis focuses on the analysis of the forest concession an instrument which grants the use of public forests for private use. From a legal perspective, the analysis is held in its component parts, which are basically the object, parties and specific legal rules, comparing it to other types of concessions, such as public service concession and authorization of use of public good. The study begins with the legal protection of the forest, given the forest concession is equally a tool of its own protection, and one goes by the concession outline and the management models of public forests in other countries, in order to achieve the main point, which is the analysis of the rules of Law No. 11,284, from 02 March 2006, reglementary limit of public forests management in Brazil. The conclusion seeks to highlight, among other aspects, the existence of an effective public policy for forest management under the control of government, built on the constitutional principle of sustainable development of the environment.

Critical being for pedagogy and social transformation: radically reimagining critical thinking in higher education

Culver, K. C. 01 August 2019 (has links)
This dissertation explores the potential for higher education to promote the development of critical being among diverse students, including three studies that employ critical quantitative approaches. The first chapter proposes critical being as an alternative to critical thinking that better reflects the purposes of higher education for the public good. In Chapter Two, I create a survey-based instrument measuring critical being, including three factors that are theoretically grounded in the work of Barnett (1997) and Davies (2015). Chapter Three examines the relationship between specific instructional practices associated with academic challenge and four-year growth in critical being among three racial and/or ethnic groups traditionally underrepresented in higher education: Black and African American students, Asian and Pacific Islander students, and Hispanic, Latinx and Chicano students. Chapter Four focuses on college instructors, exploring the relationship of individual, academic, and organizational factors with instructors’ emphasis of critical being in the classroom and their beliefs about students’ abilities and efforts. Finally, Chapter Five returns to the necessity for higher education to center critical being in order to equip students to be well-informed agents of social change. By bringing together the results of the three studies, this chapter also considers the implications of higher education for critical being, offers self-reflection on the implementation of critical quantitative approaches, and looks forward in making recommendations for future research.

From preservation to creation of value

Olsson, Krister January 2003 (has links)
This report asks the question how to balance thepreservation of cultural built heritage against other publicand private interests in local planning. The aim of the studyis to contribute to knowledge about how different actors valuethe built heritage and how they interact in planning. The studydiscusses how this knowledge can be taken into account inplanning practice. As society develops further into a knowledgesociety, the valuation of local environmental qualities seemsto be more complex than during previous decades. For thatreason the maintenance of cultural built heritage is moredifficult to handle than before. The planning process has bytradition been characterised by a strong public sectorinvolvement and by strict procedural links to the regulationsystem. However, private initiatives have come to play anincreasingly important role in the planning process. Thesechanges have led to a situation where decision-making becomesinformal. The question is if planning functions in such waythat all values represented by different interests areconsidered carefully when decisions are made for preservation,renewal or change of the builtenvironment. There are reasonsto question the notion of citizen representation by localpoliticians and experts of various kinds. The theoreticalfoundation for the study is economic valuation theory, andespecially environmental economics, in combination withnegotiation theory and planning theory. These theories are usedas a starting point for an analysis of different actors’understanding of the cultural built heritage, their incentivesfor participating in planning, and, hence, for understandingthe interaction which determines preservation practice.Empirical findings are based on a case study of planning andheritage management in the municipality of Umeå. Itincludes studies of five recently completed planning processesconcerning specific real estate properties, as well as, aquestionnaire directed to a random selection of 1000inhabitants in the municipality. The study concludes that theoutcome of planning to a substantial part is depending of theinteraction and relations between the stakeholders, and, hence,structured by what has developed as the intellectual traditionand context of the city. The study shows that the builtenvironment seen as a public good in general is not fullyacknowledged and understood. Consequently, the private goodcharacteristic of the built environment is stressed inplanning, not only by private actors, but also by the publicsector. Furthermore, the study concludes that one importantissue in the management of the cultural built heritage is todraw on the actors’incentives for preservation, hence,paying more attention to the question of future direct andindirect use of the built heritage. An actor who primarilyfocuses on existence value runs the risk of being situated inthe margin of planning, with no real influence on decisionsconcerning heritage management.

Maximizing the Productive Use of Mobile Phone Technologies for the Public Good

Temple, Chris 01 January 2012 (has links)
The ability of the mobile phone to reach and connect people like no technology before it, coupled with its productive potential to benefit private industry, governments, and the poor, makes it an extremely powerful tool for economic development – a tool that is worth investing in. Since their introduction, cell phones have demonstrated the ability to yield for the public good through improved information exchange and access to health care and financial services. In order to realize this potential, the private and public sectors must cooperate to improve regulations to encourage healthy competition and new capital investment while facilitating education in cell phone use.

How to avoid Copenhagen : An experimental economic approach to climate negotiations

Szabó, Josef January 2011 (has links)
This study got its origin in the failed climate negotiations in the Copenhagen 2009 summit. By conducting a public good game, with participants from China and Sweden, my study indicates that previous studies on public good games can predict the outcome of the game to a quit large extent even though most of my statistical tests came out statistically insignificant. My study also indicates that by framing the game as climate negotiations there were no statistical significant difference on the level of contributions in comparison to the unframed versions of the game. The awareness of the issues with emissions, global warming and other environmental problems are pretty high but even so when push comes to shove gains in the short run are prioritized to gains in the long run. There are however hypothetical willingness to come to term with the environmental issues. The results of the study indicate that the outcome of the Copenhagen summit can be avoidable but would need additional experiments made on cultural differences and behavior.

Educational value is not private! : defending the concept of public education

Bonic, Stephanie Alexis 11 1900 (has links)
The privatization of K-12 education in Canada is not new. The public and private sectors feel like natural elements of the Canadian education system because they have existed side by side since confederation. However, this thesis challenges that tradition and argues that private education undermines collective responsibility for education as a shared, public good by catering to private interests and isolating students from the public realm. Not only does private education reinforce the likelihood of socio-economic stratification, but the concept of a “public good” is increasingly destabilized as social services like education are privatized. Why, then, does the privatization of K-12 education continue to be an insignificant political issue in Canada? This question is particularly pertinent at a time when neoliberalism is in full swing in the United States, and all the time more apparent in Canada. Neoliberalism’s emphasis on the precedence of economic ideals over concerns for social welfare and democratic participation has transformed the way that we understand “value”. Drawing on a broad range of scholars including Charles Taylor, Richard Pildes, Janice Gross Stein, Henry Giroux, Francois-Lyotard and Michel Foucault, this thesis argues that the values involved in the very concept of private education reinforce, and are reinforced by, neoliberal views about the place of the individual within society, and that these values are detrimental to the concern for education as shared, public good.

Openness and the governance of human stem cell lines : a conceptual approach

George, Carol Charlene January 2013 (has links)
My research examines the extent to which features of ‘openness’ might usefully contribute to mechanisms of governance of human stem cell lines, with a view to the production of therapeutic stem cell treatments for the provision of health benefits. The impetus for the project is the UK Stem Cell Bank, a national repository for stem cell lines and the focal point of a unique set of publicly supported, non-statutory arrangements for the informal (but mandatory) oversight of human embryonic stem cell lines (hESCs) in the UK. The sharing of stem cells through this mechanism promotes public confidence in embryo and stem cell research, and supports research by making (ethically-sourced and quality-controlled) human stem cell lines widely available to researchers, but the structure and functions of the Bank also impose constraints on the imminent commercial development and manufacture of stem cell therapies for human application. My thesis examines the role of ‘openness’ in systems of governance designed to facilitate not just research but the whole trajectory of stem cell technology, from research to production and delivery of clinical treatments. What is openness and what function does it have in purposive attempts to design mechanisms that will advance stem cell technology? The bulk of my thesis maps out the conceptual foundations upon which systems of governance for the production of stem cell therapies may be grounded. It does not address the ethical and social debate surrounding embryo research and the embryonic derivation of stem cell lines, which are legally permissible in the UK. In Part I, I frame the problem of governance of ongoing use of stem cell lines as part of a larger policy endeavour related to the provision of public goods. Secondly, I propose a conception of reflexive governance that is capable of facilitation of technology in a multi-faceted heterogeneous environment. Part II explores traditional narratives of openness in science and technology, and how they might be reconceived in the context of modern scientific technology. In Part III, I apply my conception of facilitative governance to collective strategies or ‘commons’ approaches to facilitative governance. I then identify its applicability for the present UK system governing stem cell lines, and for the proposition of alternative structures and processes that might be better able to achieve the policy goal of provision of health benefits through delivery of therapeutic stem cell treatments.
