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.

Age, smoking and overweight contribute to the development of intestinal metaplasia of the cardia.

AIM: To assess the role of Helicobacter pylori (H. pylori), gastroesophageal reflux disease (GERD), age, smoking and body weight on the development of intestinal metaplasia of the gastric cardia (IMC).¦METHODS: Two hundred and seventeen patients scheduled for esophagogastroduodenoscopy were enrolled in this study. Endoscopic biopsies from the esophagus, gastroesophageal junction and stomach were evaluated for inflammation, the presence of H. pylori and intestinal metaplasia. The correlation of these factors with the presence of IMC was assessed using logistic regression.¦RESULTS: IMC was observed in 42% of the patients. Patient age, smoking habit and body mass index (BMI) were found as potential contributors to IMC. The risk of developing IMC can be predicted in theory by combining these factors according to the following formula: Risk of IMC = a + s - 2B where a = 2,...6 decade of age, s = 0 for non-smokers or ex-smokers, 1 for < 10 cigarettes/d, 2 for > 10 cigarettes/d and B = 0 for BMI < 25 kg/m² (BMI < 27 kg/m² in females), 1 for BMI > 25 kg/m² (BMI > 27 kg/m² in females). Among potential factors associated with IMC, H. pylori had borderline significance (P = 0.07), while GERD showed no significance.¦CONCLUSION: Age, smoking and BMI are potential factors associated with IMC, while H. pylori and GERD show no significant association. IMC can be predicted in theory by logistic regression analysis.

Studies on coordination of systems development process

This thesis examines coordination of systems development process in a contemporary software producing organization. The thesis consists of a series of empirical studies in which the actions, conceptions and artifacts of practitioners are analyzed using a theory-building case study research approach. The three phases of the thesis provide empirical observations on different aspects of systemsdevelopment. In the first phase is examined the role of architecture in coordination and cost estimation in multi-site environment. The second phase involves two studies on the evolving requirement understanding process and how to measure this process. The third phase summarizes the first two phases and concentrates on the role of methods and how practitioners work with them. All the phases provide evidence that current systems development method approaches are too naïve in looking at the complexity of the real world. In practice, development is influenced by opportunity and other contingent factors. The systems development processis not coordinated using phases and tasks defined in methods providing universal mechanism for managing this process like most of the method approaches assume.Instead, the studies suggest that managing systems development process happens through coordinating development activities using methods as tools. These studies contribute to the systems development methods by emphasizing the support of communication and collaboration between systems development participants. Methods should not describe the development activities and phases in a detail level, butshould include the higher level guidance for practitioners on how to act in different systems development environments.

Customer involvement in lean startup principles: case of game development studio

The objective of this thesis is to better understand customer’s role in lean startup methodology. The aim is to find out how customers are involved in lean startup methodology implantation and increase the likelihood of new venture survival. This study emphasizes the usage of customers in shaping of new product development processes within companies, through iteration and constant communication. This communication facilitates the development of features that are requested by the customers and enhances the prospects of the new venture. The empirical part of the study is a single qualitative case study that uses action research to implement the lean startup methodology into a pre-revenue venture and examines its customer involvement processes. The studied case company is Karaoke d.o.o., developing a game called kParty. The study used the theory discussed in the literature review: customer involvement (in the survey and interviews conducted for the lean startup methodology), lean principles (through the implementation of lean startup methodology) and lean startup methodology, which are the central building parts of this thesis as a whole. The thesis contributes to the understanding of customer involvement in lean startup methodology, while giving practical implications of customer orientation and product market fitting.

How CSR and stakeholder engagement encourage the development of Industrial symbiosis from the management viewpoint?

The thesis aims to understand how CSR and stakeholder engagement can contribute to the development of industrial symbiosis. Theory suggests that corporate social responsibility and stakeholder engagement theories have many similar aspects that correlate with the development of industrial symbiosis. This study is qualitative and empirical suggestions are derived from integrative analysis of literature, secondary data and case study analysis. The empirical findings from the interviews support the framework that is created from the findings of the literature review. The results discovered throughout the thesis research suggest that CSR functions as a theoretical background for industrial symbiosis and stakeholder engagement helps develop more thorough understandings of it from the management viewpoint. Empirical findings and literature review also suggest that in the developing of industrial symbiosis the key aspect are the social characteristics such as a robust management structure, trust between partners and long-term commitment to the common goals that support the development of these symbioses. Also, communication and transparency supports the development of industrial symbiosis. For managerial contribution, this thesis presents organizational practices that can help managers to understand how they can engage in effective engagement with stakeholders in the development of industrial symbiosis.

What's the difference under the gown? : new professors' development as university teachers

This study explores how new university teachers develop a teaching identity. Despite the significance ofteaching, which usually comprises 40% of a Canadian academic's workload, few new professors have any formal preparation for that aspect of their role. Discipline-specific education for postsecondary professors is a well-defined path; graduates applying for faculty positions will have the terminal degree to attest to their knowledge and skill conducting research in the discipline. While teaching is usually given the same workload balance as research, it is not clear how professors create themselves as teaching professionals. Drawing on Kelly's (1955) personal construct theory and Kegan's (1982, 1994) model ofdevelopmental constructivism through differentiation and integration, this study used a phenomenographic framework~(Marton, 1986, 1994; Trigwell & Prosser, 1996) to investigate the question of how new faculty members construe their identity as university teachers. Further, my own role development as researcher was used as an additional lens through which to view the study results. The study focused particularly on the challenges and supports to teaching role development and outlines recommendations the participants made for supporting other newcomers. In addition, the variations and similarities in the results suggest a developmental model to conceptions ofteaching roles, one in which teaching, research, and service roles are viewed as more integrated over time. Developing a teacher identity was seen as a progression on a hierarchical model similar to Maslow's (1968) hierarchy of needs.

The shifting terrain of feminist theory and activism : university-based women's centres and third wave feminism

This thesis, based on the results of an organizational ethnography of a university-based feminist organization in Southern Ontario (the Centre), traces how third wave feminism is being constituted in the goals, initiatives, mandate, organizational structure, and overall culture of university-based feminist organizations. I argue that, from its inception, the meanings and goals of the Centre have been contested through internal critique, reflection, and discussion inspired by significant shifts in feminist theory that challenge the fundamental principles of second wave feminism. I identify a major shift in the development and direction of the Centre that occurs in two distinct phases. The first phase of the shift occurs with the emergence of an antioppression framework, which broadens the Centre's mandate beyond gender and sexism to consider multiple axes of identity and oppression that affect women's lives. The second phase of this shift is characterized by a focus on (trans) inclusion and accessibility and has involved changing the Centre's name so that it is no longer identified as a women's centre in order to reflect more accurately its focus on mUltiple axes of identity and oppression. Along with identifying two phases of a major shift in the direction of the Centre, I trace two discourses about its development. The dominant discourse of the Centre's development is one of progress and evolution. The dominant discourse characterizes the Centre as a dynamic feminist organization that consistently strives to be more inclusive and diverse. The reverse discourse undermines the dominant discourse by emphasizing that, despite the Centre's official attempts to be inclusive and to build diversity, little has actually changed, leaving women of colour marginalized in the Centre's dominant culture of whiteness. This research reveals that, while many of their strategies have unintended (negative) consequences, members of the Centre are working to build an inclusive politics of resistance that avoids the mistakes of earlier feminist movements and organizations. These members, along with other activists, actively constitute third wave feminism in a process that is challenging, contradictory, and often painful. A critical analysis of this process and the strategies it involves provides an opportunity for activists to reflect on their experiences and develop new strategies in an effort to further struggles for social justice and equity.

Construing social dimensions of personality development: nurses as educators

A convenience sample of twenty registered nurses was recruited from two' general hospitals and two community college nursing schools. Kelly's (1955) Personal Construct Theory provided the theoretical framework to discover how nurses perceived themselves as educators. The nurses completed a self-administered Self-Perception Inventory (Soares, 1983) to determine their perception of self as nurse and ideal self as nurse. In an interview, each of the nurses constructed a rank-order repertory grid adapted from Kelly's (1955) Role Repertory Construct Test. Twelve constructs derived from the Self-Perception Inventory (Soares, 1983) were ranked according to a list of ten elements common to a teaching situation. Rank order correlations among the constructs were determined with Spearman's rho. Using a dependent samples t-test, significant differences were found between perceptions of current and ideal self for staff nurses. Significant differences were also found between nurse educators' perceptions of self and ideal self as nurse. No significant differences were determined in perceptions of self as nurse and ideal self as nurse between the staff nurse and nurse educator groups with an independent samples t-test. However, observations of single constructs revealed that although several constructs are shared between the groups in the perception of self in a teaching situation, both groups hold constructs that operate exclusively in their separate domains. The nature and strength of the relationships between the common and unique constructs are different for each group. Nurses I self-perceptions appear to be influenced by the historical development of nursing, role socialization during nursing education, social expectations and gender issues in the health care system.

The female coach as a role model for personal growth and development to the female adolescent athlete

Research interest on the topic of female coaches as role models has recently emerged in the coaching literature. Social learning theory (Bandura, 1963; 1977; 1986) has also emerged as an essential framework in explaining learning through modeling. Previous research has examined the coach as a role model, as well as gender differences between coaches. Several authors, with several different conclusions, have studied the significance of gender as an influencer in role modeling. Whitaker and Molstad in 1988 conducted a study focusing on the coach as a role model. What they found was when they combined the results of high school and college aged athletes; the female coach was considered to be a superior role model. The current research used a social learning theory framework to examine the benefits and intricacies of the modeling relationship between female adolescent athletes and influential female coaches. To accomplish this task, the formative experiences of thirteen adolescent female athletes were examined. Each athlete was interviewed, with each semi-structured interview focusing on extracting the salient features of a coach that the athlete identified as being the most influential in her personal development. The data from these interviews were quaHtatively analyzed using case studies. From case studies, a template emerges in which the coach/athlete relationship can be seen as an essential construct in which caring and strong role models can have lasting effects on the lives, values, and successes of adolescent female athletes.

An exploration of the impact of a mandatory quality assurance program on the staff nurse's commitment to professional development /

This study explored experiences in relation to the impact of the College of Nurses of Ontario's (CNO's) mandatory Quality Assurance (QA) program on registered nurses (RNs) working in a clinical setting of an acute care hospital. A qualitative descriptive research design was used and data collection was done in 2 stages. First, a survey with open-ended questions was given to 45 nurses. Second, 8 respondents from the survey were interviewed using a semistructured format. Data were obtained from 2 groups-diploma-prepared and post diploma-prepared RNs. Findings demonstrated that the CNO's QA program had varying influences on the RNs' learning paths, and these differences appeared to be related to the educational background of the individual. The diploma-prepared nurses reported that their commitment to professional development was influenced by their level of internal motivation, the pressures associated with time, and the need for a strong external motivator, namely the obligation of management to conduct formal performance appraisals. They further reported that the QA program played a part in positively altering their commitment to continuing education. The post-diploma baccalaureate nurses reported that the QA program played a positive role in influencing their ongoing learning, along with their level of internal motivation, the work and health care environment, and the element of professionalism. Several implications for nursing practice, theory, and fiirther research also became evident.

Towards a just community: an examination of the development of cultural citizenship rights in Canada from a communitarian perspective

The notion of citizenship, while a basic human right, has come under scrutiny. It was once assumed a liberal inspired regime of citizenship rights would reign as the primary ideological perspective in the Western world, however this has not been the case. Numerous competing paradigms have questioned the premise upon which liberal guarantees of citizenship rights are based. In particular, communitarianism has subjected liberal rights discourse to a closer examination. Communitarian theory holds that universalist principles negate any articulation of community and its internal diversity, such as cultural citizenship. It is this understanding of citizenship that has taken hold in Canada. The Canadian political experience illustrates a number of attributes associated with communitarian thought. It is a collectivist society that articulates a notion of the common good, acknowledges the internal diversity of its citizens and possesses a highly developed deliberative democratic process. To this end, Canada can be described as being more communitarian than liberal in nature in the process it has adopted to address citizenship rights. However, the type of commuIiitarianism displayed in Canada differs from the political models examined by such scholars as Michael Sandel, Iris Marion Young or Will Kymlicka. Cultural citizenship rights are fluid and malleable in Canada. While no clear guarantees of citizenship rights exist, there is a common commitment by Canadians to engage in a fair, open and inclusive deliberative process. This model is unique to Canada; it cannot be exported in that it is a product of Canadian political culture. As a result, the contemporary demands of cultural citizenship are dealt with effectively and democratically in Canada in that the proper mechanisms for public deliberation exist.

Teachers' experiences and perceptions of voluntary committee work as a vehicle for leadership development

In response to a looming leadership shortage, leadership development for teachers has become an increasingly important area of interest around the world. A review of the literature identified the key components of educational leadership development programs as effective curriculum, leadership practice, relationship building, and reflection. A gap in the research was found regarding the use of voluntary committee work as a vehicle for leadership practice. The purpose of this study was to explore teachers' perceptions of their experiences within board-level committees to determine the key factors that contributed, positively or negatively, to their leadership,pevelopment. A qualitative research design was employed using semistructured interviews with 8 participants. The key findings included a list of factors perceived by teachers as either supporting or hindering their leadership development. The supporting factors were: (a) leadership practice, (b) mentors and role models, (c) relationships and networks, and (d) positive outcomes for students. The hindering factors were: (a) lack of follow through and support, (b) committee members with a careerist approach to the experience, (c) personal and political agendas, and (d) overcommitment leading to burnout. Recommendations for practice focused on strategies to enhanc~_ the committee experience as a tool for leadership development. Recommendations for theory and research suggested more research be done on each of the 8 key factors, perceptions associated with teachers choosing to follow a leadership path, and how school boards can structure the committee process as an effective leadership development tool. This study provides a starting point for educators to begin to intentionally design, develop, and deliver voluntary committee experiences as a tool for leadership development.

The Impact of Mindfulness Meditation on Educator Growth and Professional Development: A Personal Account

This study examined the use of mindfulness meditation in educator growth and professional development. The purpose was to create recommendations for an effective mindfulness meditation practice for educators. To this end, as the researcher is an educator as well as an experienced mindfulness meditation practitioner, the research methodology was self-study through narrative inquiry. The exploration of mindfulness meditation on the researcher’s personal and professional development was viewed through the lenses of Maslow’s hierarchy of needs and Mezirow’s transformational learning theory. These theories provided an analytical framework that guided this research. Themes were drawn from the exploration and connected with academic literature. The results were a mindfulness meditation framework for educators that is based on the Socratic Method, and utilizes the conceptual frameworks of Maslow’s hierarchy of needs and Mezirow’s transformational learning theory.

Postsecondary Teaching and Learning Development Needs: Motivators and Barriers Associated With Participation in Educational Development

This study investigated instructor perceptions of motivators and barriers that exist with respect to participation in educational development in the postsecondary context. Eight instructors from a mid-size, research intensive university in south-western Ontario participated in semistructured interviews to explore this particular issue. Data were analyzed using a qualitative approach. Motivation theory was used as a conceptual framework in this study, referring primarily to the work of Ryan and Deci (2000), Deci and Ryan (1985), and Pink (2009). The identified motivators and barriers spanned all 3 levels of postsecondary institutions: the micro (i.e., the individual), the meso (i.e., the department or Faculty), and the macro (i.e., the institution). Significant motivators to participation in educational development included desire to improve one’s teaching (micro), feedback from students (meso), and tenure and promotion (macro). Significant barriers to participation included lack of time (micro), the perception that an investment towards one’s research was more important than an investment to enhancing teaching (meso), and the impression that quality teaching was not valued by the institution (macro). The study identifies connections between the micro, meso, macro framework and motivation theory, and offers recommendations for practice.
