Spiteful Strategies. The ontogeny and the practice of spite in human interaction: an experimental game theory approach and empirical applications

As estratégias de malevolência implicam que um indivíduo pague um custo para infligir um custo superior a um oponente. Como um dos comportamentos fundamentais da sociobiologia, a malevolência tem recebido menos atenção que os seus pares o egoísmo e a cooperação. Contudo, foi estabelecido que a malevolência é uma estratégia viável em populações pequenas quando usada contra indivíduos negativamente geneticamente relacionados pois este comportamento pode i) ser eliminado naturalmente, ou ii) manter-se em equilíbrio com estratégias cooperativas devido à disponibilidade da parte de indivíduos malevolentes de pagar um custo para punir. Esta tese propõe compreender se a propensão para a malevolência nos humanos é inerente ou se esta se desenvolve com a idade. Para esse efeito, considerei duas experiências de teoria de jogos em crianças em ambiente escolar com idades entre os 6 e os 22 anos. A primeira, um jogo 2x2 foi testada com duas variantes: 1) um prémio foi atribuído a ambos os jogadores, proporcionalmente aos pontos acumulados; 2), um prémio foi atribuído ao jogador com mais pontos. O jogo foi desenhado com o intuito de causar o seguinte dilema a cada jogador: i) maximizar o seu ganho e arriscar ter menos pontos que o adversário; ou ii) decidir não maximizar o seu ganho, garantindo que este não era inferior ao do seu adversário. A segunda experiência consistia num jogo do ditador com duas opções: uma escolha egoísta/altruísta (A), onde o ditador recebia mais ganho, mas o seu recipiente recebia mais que ele e uma escolha malevolente (B) que oferecia menos ganhos ao ditador que a A mas mais ganhos que o recipiente. O dilema era que se as crianças se comportassem de maneira egoísta, obtinham mais ganho para si, ao mesmo tempo que aumentavam o ganho do seu colega. Se fossem malevolentes, então prefeririam ter mais ganho que o seu colega ao mesmo tempo que tinham menos para eles próprios. As experiências foram efetuadas em escolas de duas áreas distintas de Portugal (continente e Açores) para perceber se as preferências malevolentes aumentavam ou diminuíam com a idade. Os resultados na primeira experiência sugerem que (1) os alunos compreenderam a primeira variante como um jogo de coordenação e comportaram-se como maximizadores, copiando as jogadas anteriores dos seus adversários; (2) que os alunos repetentes se comportaram preferencialmente como malevolentes, mais frequentemente que como maximizadores, com especial ênfase para os alunos de 14 anos; (3) maioria dos alunos comportou-se reciprocamente desde os 12 até aos 16 anos de idade, após os quais começaram a desenvolver uma maior tolerância às escolhas dos seus parceiros. Os resultados da segunda experiência sugerem que (1) as estratégias egoístas eram prevalentes até aos 6 anos de idade, (2) as tendências altruístas emergiram até aos 8 anos de idade e (3) as estratégias de malevolência começaram a emergir a partir dos 8 anos de idade. Estes resultados complementam a literatura relativamente escassa sobre malevolência e sugerem que este comportamento está intimamente ligado a preferências de consideração sobre os outros, o paroquialismo e os estágios de desenvolvimento das crianças.************************************************************Spite is defined as an act that causes loss of payoff to an opponent at a cost to the actor. As one of the four fundamental behaviours in sociobiology, it has received far less attention than its counterparts selfishness and cooperation. It has however been established as a viable strategy in small populations when used against negatively related individuals. Because of this, spite can either i) disappear or ii) remain at equilibrium with cooperative strategies due to the willingness of spiteful individuals to pay a cost in order to punish. This thesis sets out to understand whether propensity for spiteful behaviour is inherent or if it develops with age. For that effect, two game-theoretical experiments were performed with schoolboys and schoolgirls aged 6 to 22. The first, a 2 x 2 game, was tested in two variants: 1) a prize was awarded to both players, proportional to accumulated points; 2), a prize was given to the player with most points. Each player faced the following dilemma: i) to maximise pay-off risking a lower pay-off than the opponent; or ii) not to maximise pay-off in order to cut down the opponent below their own. The second game was a dictator experiment with two choices, (A) a selfish/altruistic choice affording more payoff to the donor than B, but more to the recipient than to the donor, and (B) a spiteful choice that afforded less payoff to the donor than A, but even lower payoff to the recipient. The dilemma here was that if subjects behaved selfishly, they obtained more payoff for themselves, while at the same time increasing their opponent payoff. If they were spiteful, they would rather have more payoff than their colleague, at the cost of less for themselves. Experiments were run in schools in two different areas in Portugal (mainland and Azores) to understand whether spiteful preferences varied with age. Results in the first experiment suggested that (1) students understood the first variant as a coordination game and engaged in maximising behaviour by copying their opponent’s plays; (2) repeating students preferentially engaged in spiteful behaviour more often than maximising behaviour, with special emphasis on 14 year-olds; (3) most students engaged in reciprocal behaviour from ages 12 to 16, as they began developing higher tolerance for their opponent choices. Results for the second experiment suggested that (1) selfish strategies were prevalent until the age of 6, (2) altruistic tendencies emerged since then, and (3) spiteful strategies began being chosen more often by 8 year-olds. These results add to the relatively scarce body of literature on spite and suggest that this type of behaviour is closely tied with other-regarding preferences, parochialism and the children’s stages of development.

Pausing at the river's edge : a narrative inquiry into the practice of a reading teacher /

In this narrative self-study I retell and connect the stories ofmy personal journey with literacy from childhood to the present. I use narrative as both methodology and method as I story my life experiences and my personal encounters with literacy. The heart ofmy reflections comes from the pages of personal journals written and storied over many years of trying to make meaning of powerful literacy experiences in my life. Now, in going back through the stories and reconstructing meaning, I make connections between the memories along the journey and the place from which I now tell my story. The interpretations I construct give voice to beliefs 1 have lived by and illuminations to moments in time that I have come to see with new eyes as I have engaged in this inquiry. The journey and self-reflection within the pages of this inquiry provide understanding of the driving force behind my personal passion for literacy. I am better able to understand my motivations and share the stories that validate my personal and professional path through time.

Le rôle de l’évaluation économique dans la pratique des médecins de famille = The role of economic evaluation in the practice of family physicians

L’évaluation économique en santé consiste en l’analyse comparative d’alternatives de services en regard à la fois de leurs coûts et de leurs conséquences. Elle est un outil d’aide à la décision. La grande majorité des décisions concernant l’allocation des ressources sont prises en clinique; particulièrement au niveau des soins primaires. Puisque chaque décision est associée à un coût d’opportunité, la non-prise en compte des considérations économiques dans les pratiques des médecins de famille peut avoir un impact important sur l’efficience du système de santé. Il existe peu de connaissances quant à l’influence des évaluations économiques sur la pratique clinique. L’objet de la thèse est de comprendre le rôle de l’évaluation économique dans la pratique des médecins de famille. Ses contributions font l’objet de quatre articles originaux (philosophique, théorique, méthodologique et empirique). L’article philosophique suggère l’importance des questions de complexité et de réflexivité en évaluation économique. La complexité est la perspective philosophique, (approche générale épistémologique) qui sous-tend la thèse. Cette vision du monde met l’attention sur l’explication et la compréhension et sur les relations et les interactions (causalité interactive). Cet accent sur le contexte et le processus de production des données souligne l’importance de la réflexivité dans le processus de recherche. L’article théorique développe une conception nouvelle et différente du problème de recherche. L’originalité de la thèse réside également dans son approche qui s’appuie sur la perspective de la théorie sociologique de Pierre Bourdieu; une approche théorique cohérente avec la complexité. Opposé aux modèles individualistes de l’action rationnelle, Bourdieu préconise une approche sociologique qui s’inscrit dans la recherche d’une compréhension plus complète et plus complexe des phénomènes sociaux en mettant en lumière les influences souvent implicites qui viennent chaque jour exercer des pressions sur les individus et leurs pratiques. L’article méthodologique présente le protocole d’une étude qualitative de cas multiples avec niveaux d’analyse imbriqués : les médecins de famille (niveau micro-individuel) et le champ de la médecine familiale (niveau macro-structurel). Huit études de cas furent réalisées avec le médecin de famille comme unité principale d’analyse. Pour le niveau micro, la collecte des informations fut réalisée à l’aide d’entrevues de type histoire de vie, de documents et d’observation. Pour le niveau macro, la collecte des informations fut réalisée à l’aide de documents, et d’entrevues de type semi-structuré auprès de huit informateurs clés, de neuf organisations médicales. L’induction analytique fut utilisée. L’article empirique présente l’ensemble des résultats empiriques de la thèse. Les résultats montrent une intégration croissante de concepts en économie dans le discours officiel des organisations de médecine familiale. Cependant, au niveau de la pratique, l'économisation de ce discours ne semble pas être une représentation fidèle de la réalité puisque la très grande majorité des participants n'incarnent pas ce discours. Les contributions incluent une compréhension approfondie des processus sociaux qui influencent les schèmes de perception, de pensée, d’appréciation et d’action des médecins de famille quant au rôle de l’évaluation économique dans la pratique clinique et la volonté des médecins de famille à contribuer à une allocation efficiente, équitable et légitime des ressources.

Establishing a community of practice of researchers, practitioners, policy-makers and communities to sustainably manage environmental health risks in Ecuador

The Sustainably Managing Environmental Health Risk in Ecuador project was launched in 2004 as a partnership linking a large Canadian university with leading Cuban and Mexican institutes to strengthen the capacities of four Ecuadorian universities for leading community-based learning and research in areas as diverse as pesticide poisoning, dengue control, water and sanitation, and disaster preparedness. By 2009, train-the-trainer project initiation involved 27 participatory action research Master’s theses in 15 communities where 1200 community learners participated in the implementation of associated interventions. This led to establishment of innovative Ecuadorian-led master’s and doctoral programs, and a Population Health Observatory on Collective Health, Environment and Society for the Andean region based at the Universidad Andina Simon Bolivar. Building on this network, numerous initiatives were begun, such as an internationally funded research project to strengthen dengue control in the coastal community of Machala, and establishment of a local community eco-health centre focusing on determinants of health near Cuenca. Alliances of academic and non-academic partners from the South and North provide a promising orientation for learning together about ways of addressing negative trends of development. Assessing the impacts and sustainability of such processes, however, requires longer term monitoring of results and related challenges.

Liberation or limitation? Understanding Iyengar Yoga as a practice of the self

This article explores the Foucauldian notions of practices of the self and care of the self, read via Deleuze, in the context of Iyengar yoga (one of the most popular forms of yoga currently). Using ethnographic and interview research data the article outlines the Iyengar yoga techniques which enable a focus upon the self to be developed, and the resources offered by the practice for the creation of ways of knowing, experiencing and forming the self. In particular, the article asks whether Iyengar yoga offers possibilities for freedom and liberation, or whether it is just another practice of control and management. Assessing Iyengar yoga via a ‘critical function’, a function of ‘struggle’ and a ‘curative and therapeutic function’, the article analyses whether the practice might constitute a mode of care of the self, and what it might offer in the context of the contemporary need to live better, as well as longer.

The practice of sustainable facilities management: Design sentiments and the knowledge chasm

The construction industry with its nature of project delivery is very fragmented in terms of the various processes that encompass design, construction, facilities and assets management. Facilities managers are in the forefront of delivering sustainable assets management and hence further the venture for mitigation and adaptation to climate change. A questionnaire survey was conducted to establish perceptions, level of commitment and knowledge chasm in practising sustainable facilities management (FM). This has significant implications for sustainable design management, especially in a fragmented industry. The majority of questionnaire respondents indicated the importance of sustainability for their organization. Many of them stated that they reported on sustainability as part of their organization annual reporting with energy efficiency, recycling and waste reduction as the main concern for them. The overwhelming barrier for implementing sound, sustainable FM is the lack of consensual understanding and focus of individuals and organizations about sustainability. There is a knowledge chasm regarding practical information on delivering sustainable FM. Sustainability information asymmetry in design, construction and FM processes render any sustainable design as a sentiment and mere design aspiration. Skills and training provision, traditionally offered separately to designers and facilities managers, needs to be re-evaluated. Sustainability education and training should be developed to provide effective structures and processes to apply sustainability throughout the construction and FM industries coherently and as common practice.
