O tema central da tese é a educação para a paz na escola. É abordado a partir da bibliografia disponível e da investigação realizada durante o ano letivo de 2009 com 151 adolescentes de quatro escolas da rede pública e particular da região metropolitana de Belo Horizonte. A pergunta fundamental e motivadora da tese é: é possível educar para a paz na escola? Com o foco nesta questão central e a partir da hipótese inicial de que na medida em que educarmos comportamentos pró-sociais na escola, inibiremos os comportamentos violentos, foi realizada a pesquisa de campo com o objetivo geral de investigar os fatores que, numa proposta de educação para a paz, favorecem o desenvolvimento de comportamentos pró-sociais nos adolescentes e evitam comportamentos violentos no contexto escolar. Foram objetivos específicos da investigação realizada os seguintes: entender a educação para a paz como um compromisso fundamentado na experiência religiosa expressada nas diferentes tradições e como elemento central numa proposta de diálogo inter-religioso; estudar a adolescência como etapa privilegiada de intervenção psicopedagógica; analisar os efeitos da aplicação de um programa de intervenção psicopedagógica de educação para a paz na escola. A pesquisa combina métodos qualitativos e quantitativos ao usar o modelo experimental-estatístico, com um delineamento experimental multigrupo de medidas repetidas pré-teste/pós-teste, junto com o observacional-descritivo, privilegiando a observação participante. O primeiro capítulo é dedicado à fundamentação teológica da tese desde uma perspectiva pluralista e libertadora que privilegia o diálogo inter-religioso. O segundo capítulo é dedicado à fundamentação psicopedagógica da pesquisa e reflete sobre o binômio educação integral para a paz / comportamento pró-social. O terceiro capítulo descreve o percurso e a opção metodológica adotada na investigação. Finalmente o quarto analisa os dados coletados tomando como referência básica as quatro variáveis trabalhadas no programa de intervenção implementado com os adolescentes sujeitos da investigação e relacionadas todas elas com comportamentos pró-sociais: autoestima, expressão/compreensão de sentimentos, relações de cooperação e resolução de conflitos. A pesquisa constatou a efetiva diminuição dos comportamentos violentos dos adolescentes na sala de aula, especialmente nas escolas da rede pública participantes, junto com sinais de avanços na manifestação de comportamentos pró-sociais, mostrando que é possível e viável educar para a paz nas escolas através de programas de intervenção psicopedagógica específicos e de fácil implementação. / The central theme of theses is education for the peace at school. This theme is discussed based on the bibliography available and on investigation. The investigation was carried through the school year of 2009 with 151 adolescentes from four public schools in the metropolitan region of Belo Horizonte. The fundamental and motivating question of the thesis is: Is it possible to educate for peace at school?With the focus on this central issue and from the initial hypothesis that the extent to educate pro-social behavior at school, inhibit violent behavior. A field research was conducted with the aim to investigate the factors that, in a proposal of education for the peace, favors the development of pro-social behaviors in the adolescents and prevents violent behavior at school. Our research was motivated by the following points: understanding education for the peace as a religious experience based on the commitment expressed in the different traditions and as a central element in a proposal for inter-religious dialogue and to study the adolescent stage as prime psychopedagogical intervention, analyze the implementation of a psychopedagogical intervention program of education for the peace at school. The research combines qualitative and quantitative methods to use the experimental-statistical model, with a multigroup experimental design with repeated measures pre-test/post-test, along with observational and descriptive, focusing on participant observation. The first chapter is related to the theological foundation of the research from a pluralistic and liberating perspective that focuses interreligious dialogue. The second chapter refers to the psychopedagogical fundamentals of the research and reflects on the dual integral education for peace / pro-social behavior. The third chapter describes the course and the methodological approach used to carry out this research. The fourth chapter is based on the analysis and comments of collected data. For that purpose reference was made to the four parameters worked in the program of intervention implemented with adolescent subjects of the investigation and all of them related to prosocial behaviors: self-esteem, expression / comprehension of feelings, cooperation relations and conflict resolution.The research showed the effective reduction of violent behaviors of adolescents in the classroom, especially in public schools participating, along with signs of progress in the demonstration of prosocial behaviors, showing that it is possible and feasible to educate for the peace at schools through psychopedagogical intervention programs which are easily implemented.

O presente trabalho é uma avaliação do efeito da administração de ocitocina nasal sobre o perfil de ativação do sistema nervoso autônomo e níveis salivares de cortisol, buscando compreender a relação entre esses vetores dentro da perspectiva da teoria polivagal e da concepção da ocitocina como um peptídeo de ação pró-social. A hipótese testada foi se o sistema pró-social, mediado pela ocitocina, exerce um efeito de ativação no ramo parassimpático, diminuindo o nível salivar de cortisol, comprovando o efeito anti-stress dessa molécula, ao desligar o sistema de alarme, reação filogenética para a preparação fisiológica para a interação social (relaxamento e tranquilidade). Para tanto, utilizou-se do Trial Social Stress Test, cuja tarefa é falar em público, situação em que parâmetros autonômicos foram medidos em sujeitos humanos, assim como o nível de cortisol salivar avaliado, em dois grupos: um experimental (com administração de ocitocina) e um controle (com administração de placebo) e em dois momentos (pré e pós stress social), relacionando-os a dados de personalidade (teste Bateria Fatorial da Personalidade). Os achados foram indicativos que a ocitocina exerce um efeito inibitório notável sobre os níveis de cortisol, não encontrando dados conclusivos sobre o vinculo ou não da atividade parassimpática relacionada com a presença da ocitocina e baixo nível de cortisol, embora se tenha encontrado forte influência da presença da ocitocina na atividade cardíaca (mediada pelo sistema nervoso autônomo). O fator de personalidade se mostrou bastante relevante nos resultados de cortisol e efeitos de ocitocina, correlacionados com o índice de Neuroticismo e se encontrou indicativos de que outros fatores de personalidade podem também ser importantes / The present work is an evaluation of nasal administration effect of oxytocin over the activation profile of the autonomic nervous system and salivary levels of cortisol, seeking to understand the relationship between these vectors within the perspective of the polyvagal theory and the conception of oxytocin as a pro social peptide. The hypothesis tested was whether the pro-social system, mediated by oxytocin, exerted an activation effect over the parasympathetic branch, reducing the salivary level of cortisol, proving the anti-stress effect of this molecule, when the alarm system was turned off, phylogenetic reaction to the physiological preparation for social interaction (relaxation and tranquillity). For this purpose, the Trial Social Stress Test was used, whose task is to speak in public, in which its autonomic parameters were measured, as well as the level of salivary cortisol evaluated, in two groups: one experimental (with oxytocin administration) and one control (with placebo administration) and at two moments (pre and post social stress), relating these results with personality data (Personality Factor Battery test). The findings were indicative that oxytocin exerts a remarkable inhibitory effect on cortisol levels, and we did not find conclusive data about the relationship or not of the parasympathetic activity related to the presence of oxytocin and low cortisol level, although strong oxytocin influence was found over the cardiac activity (mediated by the autonomic nervous system). The personality factor was shown to be very relevant in the cortisol and oxytocin effects correlated with the Neuroticism Index and it was found that other personality factors may also be important

This thesis addresses three themes relating to climate change. The first is which types of fossil fuel to leave in the ground when they can differ in both their extraction cost and emissions rate. The analysis shows that without resource constraints there will always be use of at least one fossil fuel in the steady-state. With exhaustion constraints, any fossil fuel that has a lower extraction cost than the marginal cost of the backstop will be extracted in finite time regardless of the emissions rate. The only environmental consideration is the timing of extraction rather than leaving fossil fuel stock in the ground forever. The second theme is how altruistic concern of individuals for the well-being of others influences the socially optimal consumption levels and optimal emissions tax in a global context. If individuals have altruistic concern but believe that their consumption is negligible, they will not change their behaviour. However, non-cooperative governments maximising domestic welfare will internalise some of the damage inflicted on other countries depending on the level of altruistic concern individuals have and the cooperative optimum also changes as altruism leads individuals to effectively experience damage in other countries as well as the direct damage to them. Still, for behaviour to change, individuals need to make their decisions in a different way. The third chapter develops a new theory of moral behaviour whereby individuals balance the cost of not acting in their own self-interest against the hypothetical moral value of adopting a Kantian form of behaviour, asking what would happen if everyone else acted in the same way as they did. If individuals behave this way, then altruism matters and it may induce individuals to cut back their consumption. But nevertheless the optimal environmental tax is exactly the same as the standard Pigovian tax.

Comment résoudre les problèmes de congestion liés au développement urbain ? Les investissements massifs dans les infrastructures et le traitement monétaire et coercitif des comportements ayant montré leurs limites, nous proposons d'explorer la possibilité de favoriser les comportements positifs (covoiturage, vélo, télétravail). Nous commençons par élargir le modèle comportemental de l'individu en posant comme préalable à l'étude des motivations la prise en compte du cadre dans lequel il se situe. Nous justifions théoriquement cet apport principalement par les travaux du psychologue Daniel Kahneman et du sociologue Ervin Goffman. Nous précisions ensuite notre démarche méthodologique : en montrant combien la démarche des expérimentations de laboratoire est reliée à l'hypothèse comportementale de l'homo œconomicus, nous montrons la cohérence de notre hypothèse de cadre avec celle des expériences de terrain. Nous décrivons ensuite trois expériences visant à montrer (i) comment le cadre correspond à une représentation confortée par un discours dominant (ii) l’importance de la mesure rétroactive de cette représentation et (iii) comment les motivations agissent à l’intérieur de ce cadre. Nous en déduisons plusieurs principes susceptibles de favoriser un changement de comportements de mobilité à même de traiter le problème de congestion : (i) la place de l’individu dans les schémas de transports, (ii) le temps ou le bien être comme indicateur de mesure et (iii) les représentations collectives comme support de coordination. / How to solve congestion problems related to urban development? As the massive investment in infrastructure and the monetary and coercive treatment of behaviors have shown their limits, we propose instead to explore the promotion of positive behavior (carpooling, biking, telecommuting). We start by expanding the behavioral model of the individual, by taking into account the context (frame) in which it happens. We justify this contribution primarily through the work of the psychologist Daniel Kahneman and the sociologist Ervin Goffman . Then we clarify our methodological approach: by showing how the process of laboratory experiments is connected to the behavioral factors of the homo oeconomicus, we show the consistency of our frame hypothesis with field experiments. We then describe three experiments to show (i) how the frame is underpinned by a dominant discourse (ii) the importance of the retroactive measure of this representation and (iii) how motivations acts within that frame. We derive several principles to promote a change of mobility behavior able to treat congestion: (i) the place of the individual in transport schemes, (ii) using time or well-being as a measurement indicator and (iii)collective representations as coordination enablers.

One of the main environmental policy challenges is convincing individuals and organisations to engage in socially desirable courses of action; that is, to have them internalise the consequences of their decisions. As contributions from institutional and behavioural economics have indicated, policies aimed at fostering pro-social action can be ineffective and even counterproductive if the interests and concerns of the relevant actors are not properly considered throughout the policy process. In fact, international conventions and national legislation around the world generally recommend stakeholder involvement in order to properly address pressing environmental challenges. The evidence that underpins and informs this recommendation, however, is still insufficient and scattered across different strands of literature. On the one hand, research on participatory governance has indeed systematically documented the potential for policymakers and resource managers to obtain high-quality, context-specific and legitimate input for environmental policymaking from participatory processes. On the other, the available research has also cast doubt on the potential of participatory processes to produce concrete change in (pro-social) action on the ground. In general, the success of these processes ultimately depends on their design, implementation and context. However, most of these conclusions stem from rich qualitative accounts of participatory processes, structured comparisons of cases and systematic reviews of case studies and the available literature. With this type of evidence, it is difficult to neatly identify the impact of participatory interventions on pro-social and cooperative behaviour and systematically assess the underlying mechanisms. This thesis addresses these knowledge gaps. The thesis investigates the extent to which and the mechanisms by which participatory interventions could foster (or hinder) pro-social and collective action for natural resource management and environmental protection. It comprises four chapters, each constituting a stand-alone, self-contained academic paper. Throughout the different chapters, the thesis reviews and integrates insights from the literature on participatory governance and from the institutional and behavioural analyses of pro-social and collective action. Furthermore, using two laboratory economic experiments (Chapters 3 and 4) and one framed lab-in-the-field experiment (Chapter 5), the thesis systematically assesses specific hypotheses concerning the potential impacts of participatory interventions on cooperative and pro-social behaviour and the underlying mechanisms of these impacts. The introductory chapter of the dissertation gathers, presents and discusses the insights gathered from each chapter. It expands on the motivations for the thesis, presents the general and specific research gaps and questions the thesis tackles and clarifies the conceptual, theoretical and methodological foundations upon which the thesis is grounded. Chapter 2 (entitled Participatory interventions for collective action in environmental and natural resource management) reviews the literature on participatory governance together with the literature on collective action in natural resource and environmental management. The main goal of this review is to contribute to integrating the main insights from both strands of literature regarding (a) the potential of participatory interventions to foster collective action and (b) the channels through which they might foment (or hinder) collective action. It therefore seeks to help integrate the insights from these different strands of literature, which, although related, have generally been disconnected until now. The chapter draws on the Institutional Analysis and Development (IAD) framework to organise these insights within a coherent conceptual framework. As the results of this literature review indicate, participatory interventions have the potential to foster collective action through two channels. Firstly, by helping resource users to change (and enhance) the rules, norms and strategies that constrain and guide their behaviour (the indirect channel) and, secondly, by directly influencing the specific behavioural factors (e.g. knowledge, trust, preferences, perceptions and beliefs) that collective action hinges upon (the direct channel). However, to sustain collective action, the relevant literature has consistently emphasised that trust needs to be continually cultivated and ensured. Therefore, in line with insights from earlier studies on participatory governance, the results of this literature review also indicate that practitioners and policymakers must not only design participatory interventions carefully to effectively build the trust needed to heighten and sustain collective action, but participatory interventions must also be adequately embedded within the broader (social-ecological and governance) context, providing for follow-up, enforcement, monitoring and conflict-resolution mechanisms. From Chapter 3 through Chapter 5, the thesis focuses on the direct channel, studying the potential of participatory interventions to directly influence behaviour within relevant economic action situations such as social dilemma and distributive action situations. Within a given environment and institutional context, the studies recreate processes commonly facilitated within participatory interventions. Chapter 3 assesses the effects of externally structured and facilitated processes of information exchange, and Chapters 4 and 5 examine the impact of inducing perspective-taking via role-switching techniques (Chapter 4) and instructions (Chapter 5). Thanks to this experimental approach, it is possible to systematically assess the behavioural impacts of these types of processes as well as the underlying mechanisms. Chapter 3 (entitled Structuring communication effectively for environmental cooperation) starts by reviewing previous experimental studies on the effects of two-way communication in social dilemmas to identify the elements that are commonly involved in effective communication processes. This review notes four cooperation-enhancing components of communication: (i) problem awareness, (ii) exploration of strategies to tackle the problem at hand, (iii) agreement on desirable joint strategies and (iv) ratification of agreed-upon strategies. A total of 560 students at Osnabrück University participated in a laboratory implementation of a voluntary contribution mechanism; a public goods game. The experiment implemented a series of interventions that represented these components of communication and contrasted the resulting levels of cooperation with the average outcomes of control groups interacting under either free (unstructured) communication or no communication whatsoever. The intervention that facilitated agreement on a common strategy (i.e. the combination of (ii) and (iii)) was particularly effective at boosting cooperation. Furthermore, combined with interventions promoting problem awareness and ratification, this intervention produced levels of cooperation similar to the average levels of cooperation observed in groups with free-form communication. The results of this experiment expand the understanding in the literature of the role of communication in social dilemmas and provide insights into the potential of structured and facilitated processes of information exchange and social interaction to foster collective action for environmental management. Chapter 4 (The effects of inducing perspective-taking through role reversal in a give-and-take a dictator game on pro-social behaviour) and Chapter 5 (Perspective-taking for pro-social behaviour in watershed management) deal with the effects of inducing perspective-taking on unilateral pro-social behaviour. The results outlined in Chapter 4 indicate that perspective-taking, induced through role reversal, can be associated with significant average changes in the participants’ self-reported state of emotions (in terms of both empathic and positive as well as in distressing and negative emotions). The emotional reactions that the role reversal seems to influence, however, do not appear to result in significantly more (or less) pro-social behaviour. The chapter explores and discusses two plausible explanations for these results, namely the transient effects of emotional reactions and the opposing effects of diverging emotional reactions on pro-social behaviour. These results come from the analysis of data from 144 students at Osnabrück University who participated as dictators in a laboratory implementation of a give-and-take dictator game. The design of the experiment allows the identification of the effect of inducing decision-makers to experience the other person’s position through unilateral role reversal on pro-social behaviour. During the simulation round, dictators in treatment groups experienced how it would feel to be in the role of the recipient. Dictators in the control groups only learned about the distributional consequences of their allocation decisions on recipients. Hence, through a treatment comparison, it was possible to single out the effects resulting from temporarily taking on the position of the other participant. To understand the underlying drivers of a potential behavioural change, the study elicited participants’ emotional states both before and after the simulation round. The results in Chapter 5 indicate that inducing perspective-taking can be associated with relatively greater pro-social behaviour based on an experimental study of downstream farmers’ behaviour in a watershed management context. Moreover, the provision of information on the social-ecological context during the perspective-taking exercise cannot account for the different behavioural patterns in the treatment and control groups. These results come from a lab-in-the-field experiment carried out with 177 downstream farmers in a Peruvian watershed. In the experiment, farmers in the treatment groups were motivated to imagine the upstream farmers’ perspective (i.e. to think about their thoughts and feelings) before deciding on whether or not to contribute to an initiative in the upper watershed. The initiative intends to help upstream farmers improve their well-being without compromising the water supply downstream. The behaviour of farmers in the treatment groups was compared against the behaviour of farmers in the control groups wherein perspective-taking was not induced. Taken together, the results of Chapter 4 and Chapter 5 illustrate the potential of inducing perspective-taking—commonly promoted in participatory processes—to trigger pro-social behaviour in economic situations. It can indeed alter relevant behavioural variables and trigger pro-social behaviour in distributive and social-dilemma situations. Nevertheless, as the literature on perspective-taking has previously indicated, the final effects depend on the specific procedures by which and the situations and contexts wherein perspective-taking is induced. Based on these findings, it is possible to sustain that participatory interventions do have the potential to effect changes in pro-social and cooperative behaviour at both the collective and individual level. Whether this impact is realised or hindered hinges on the procedures and contexts of participatory interventions. It would also depend on the mechanisms provided to follow up on the initiated processes and sustain and build upon the early outcomes. The contributions of this thesis are threefold. Firstly, it integrates insights from the literature on the institutional and behavioural analysis of pro-social and collective action and the literature on participatory governance for natural resource management. Secondly, it generates new evidence, based on experimental methods, in terms of the potential for participatory interventions to foster pro-social and collective action, and in terms of the mechanisms by which participatory methods and processes could effectively impact (or hinder) pro-social and cooperative behaviour. In this way, the thesis helps to bridge the gap of knowledge in terms of how participatory interventions can effectively change behaviour and, subsequently, encourage socially desirable social-ecological outcomes. In doing so, it also adds to the understanding of pro-social and cooperative human behaviour and the way that the processes of information-exchange and perspective-taking, which are often facilitated by participatory processes, may (or may not) advance it. Research on participation is, however, still ongoing and, in terms of the way forward, the thesis makes a third, methodological contribution. It demonstrates how experimental research in both the laboratory and in the field, conducted under a coherent conceptual and methodological framework, can complement one another and shed light on the extent to which and the means by which participatory interventions can produce changes in behaviour. The experimental method, in terms of both laboratory and field experiments, can therefore complement the set of methods traditionally employed to analyse participatory processes. The results of the studies comprising the thesis underscore the importance of carefully analysing the policy process. As contributions from the behavioural literature have repeatedly indicated, human behaviour is driven by a combination of self-regarding, social and procedural preferences. Hence, addressing pressing environmental challenges involving externalities and social dilemmas not only entails getting the policy design right to synergistically coordinate and orchestrate these different types of preferences. It also requires careful design, analysis and implementation of the activities and methods that structure and facilitate stakeholder interactions throughout the policy process.

BACKGROUND: Today’s societal changes, including high rate of change and increasing information flows, are increasing the demand on the individual mental capacity. It becomes increasingly difficult to analytically process all the different dilemmas and everyday decisions as individuals have a limited mental capacity available to make these decisions. Thus, it has been suggested that ego-depleted relies more heavily on intuition, which is less burdensome, when making decision. However little is known about to what extent intuitive decisions differ from analytic. Are ego-depleted individuals more or less likely to maximize outcome in moral dilemmas involving conflicting values? Do ego depleted individuals become more or less willing to cooperate? Do ego depleted individuals become more or less altruistic? Is our intuition more or less in accordance with Homo Economicus?AIM: Starting from a Dual Process perspective on decision-making the aim of this study is to examine how ego depletion affects moral judgment and pro-social decisions.METHOD: A laboratory experiment involving 115 subjects, using real monetary incentives, was conducted among students at Linköping University. Subjects were randomized into one of two treatments. Everything was identical across treatments except for the initial ego-depletion manipulation. Using a standard paradigm for ego-depletion subjects in treatment 1 were put under high cognitive load while subjects in treatment two were put under low cognitive load. Subjects faced 16 questions divided into four different decision tasks: Moral dilemmas, Public Goods game, two types of Dictator Game where the type of sacrifice subjects could make in order to contribute money to charity was varied.RESULTS: Subjects in the high cognitive load treatment made fewer consequentialists moral judgments compared to other subjects (p = 0.075). The effect is especially strong when looking only at high-conflict dilemmas such as Crying Baby. No difference between treatments was found for the public goods games. In the dictator game involving monetary sacrifice subjects donated less money to charity when put under high cognitive load. However the finding was not significant (p = 0.292). No difference was found in the dictator game involving effort as personal sacrifice since almost everyone chooses to donate to charity.CONCLUSION: According to The Dual Process perspective this essay shows that intuitive thinking does not evidently lead to that they makes decision that more or less is in accordance with Homo Economicus. The connection between ego depletion and pro-social decisions is more complex. Further research needs to investigate which different mental shortcuts that individuals uses in various types of pro-social decisions and why intuitive and analytical decision-making differ between different decisions. Further research within the area can identify potential mechanisms and policies that can support individuals’ capacity to make decisions in accordance with their own and society’s preferences.

The work has two parts {--} teoretic, which consists concepts connected with developing creativity and conditions, which has influence on creativity. Art project is the second {--} practical part with introduction and explaining of the structure. Art project is inspired by fairy tale The Little Prince and contains prosocial topics and creative activities of many art spheres.

In the thesis on the pro-social traits of workers in helping (assistance-providing) professions I dedicate myself to pro-social behavior, empathy and the basic characteristics of personality issuing from the five-factor personality model {--} The Big Five. Most professionals agree that pro-social behavior and empathy belong among the basic characteristics that assistance-providing professionals should have. An important role is also the personality of the care provider. The listed constructs and connections among them however remain the home environment of empirical research and thereby represent the phenomena regarding which there exist few verified findings. The goal of the paper rests in fining the level of empathy and personal dispositions in accordance with the Big Five model that could influence pro-social behavior in selected groups of assistance-giving professionals. The factors in question are neuroticism, extroversion, and openness to experience, graciousness and conscientiousness. Data collection took place with the help of two psychodiagnostic questionnaires. The IRI questionnaire measures level of empathy and the NEO-FFI questionnaire was used for diagnosing the five personality dimensions. The study was quantitative. The monitored set included respondents from three assistance-giving professions {--} nurses, members of the Czech Republic Fire Rescue Corps, and elementary-school teachers. The results confirmed the hypothesis that care providing workers show higher levels of empathy in comparison to the population average, and the hypothesis that these professionals show a higher level of personality traits that, in an interpersonal context, display positive orientation towards others, that is that they are more extroverted and gracious in comparison with the population average, was refuted. These results make it possible to consider that the relationship between the basic personality dimensions and pro-social tendencies may be mediated by the level of empathy with regard to other psychological constructs and the results of social learning. Conclusions cannot be generalized, due to a relatively small sample group. For this purpose it would be interesting to carry out a professional study, which would exceed, in its scope and possibilities, the usual requirements of a thesis paper.

En raison de la nature des biens et services distribués à caractère social et collectif et des missions sociales rendues, le secteur public est davantage susceptible d’attirer des travailleurs développant une motivation pro sociale que le secteur privé. Notre thèse élabore des tests empiriques afin de révéler la présence de cette forme de motivation chez les agents du secteur public. Notre premier chapitre cherche à évaluer les différences de satisfaction dans l’emploi au regard de diverses caractéristiques le définissant afin de mettre au jour des préférences différentes entre les salariés des secteurs public et privé, nous renseignant ainsi sur leur source de motivation respective. Nous trouvons que les employés du secteur public font montre d’une motivation pro sociale supérieure aux salariés du privé en étant prêts à travailler de plus longues heures tout en acceptant des salaires plus faibles que les salariés du privé. Dans les deux chapitres suivants, nous testons l’existence d’un comportement de don du travail supérieur de la part des agents du secteur public à l’aide de deux mesures de sur-effort dans l’emploi : la probabilité de faire des heures supplémentaires non payées et le phénomène du présentéisme au travail. Les résultats montrent que la présence d’une motivation pro sociale des agents du secteur public ne les conduit pas à fournir un don d’effort supérieur aux salariés du privé. Toutefois, dès lors que l’on cherche à modifier les méthodes d’incitation et d’organisation du travail ou encore la source de leur motivation spécifique, les agents du secteur public réduisent ce comportement d’effort supplémentaire gratuit. / Because of the nature of the public goods provided and the social services performed, the public sector is more likely to attract workers with a higher prosocial motivation than the private sector. Our thesis develops empirical tests to reveal the presence of this form of motivation among public sector agents. Our first chapter seeks to evaluate the differences in job satisfaction, defined with respect to various characteristics, in order to identify different preferences between employees in the public and private sectors, thus providing information on their respective sources of motivation. We find that public sector employees show greater prosocial motivation than private sector employees, the former being willing to work longer hours and accepting lower wages than the latter. In the two following chapters, we test whether public sector employees put more effort in the workplace, all other things being equal, using two measures of overeffort: the probability of working unpaid overtime and the phenomenon of presenteeism at work. The results of these studies highlight the presence of a pro-social motivation of public sector employees which however does not lead them to provide an effort greater than that provided by private sector employees. We find that the incentive to effort takes different forms according to the specific managerial and organizational characteristics of the work, and is compatible with motivations of different nature. Finally, we show that if such specific motivation did not exist, the provision of effort of public employees would be less frequent.

Submitted in fulfillment of the requirements of Ph. D (Public Managment), Durban University of Technology, Durban, South Africa, 2017. / Using historic and ethnographic data collected from KwaZulu-Natal, this study examines food consumption from the Zulu Cosmology epistemic point of view. The study highlights as a prosocial behaviour that reduces the importance of self in favour of pro social norms of sharing and selflessness. In other words, personhood is understood as a process and the product of interconnectedness experienced in social spaces. Pro-social behaviour is therefore seen as a determinant of harmonious and social cohesive communities. The study concluded that social cohesive communities develop a set of cultural protocols and boundaries that reward prosocial norms and punish antisocial behaviour. Social cohesion as a concept was also found to be inseparable from the notion of shared values, identities and norms. The study delved deeper and found that the land, the livestock and the cultural rituals to honour the living and the dead defined a unique interconnectedness of the Zulu person to his culture. Eating and eaten products were part of a uniting culture that linked a Zulu man, woman, girls, old men and women to other people, their animals and their land. Zulu people lived for, and with, other people in peace. No man or family would go hungry. Immediately that becomes known, another man would give the destitute man a few cattle to start his own flock and feed his family. This and other eating rituals contributed to a strong, peaceful and social cohesive nation of King Shaka ka Senzangakhona. On the basis of the understanding of the cultural rituals, their link with the land and animal the study concluded that land restitution and agrarian policies can be enhanced by taking into consideration their need for land to cultivate vegetables and fruits that have cultural meaning, policies that enable to have livestock as well as space to practise their culture. The study is envisaged to inspire social welfare and community development policies that instil the prosocial values of Ubuntu and interconnectedness. / D
