Tourism in the Northeast of Brazil was introduced as an alternative economic development for the Region by federal promoting policies that focused primarily in structuring the local geographic area. With the completion of these structuring actions, mass tourism expanding the area, as well as spread actions based on cooperation and formalization of governance institutions. This study aimed to examine the relationship between the life cycle of the tourism product 'Coastal Cities of Natal and the cooperation strategies in a historical perspective. Thus was submitted to the life cycle of the tourism product 'Coastal Cities of Natal ; the major projects of tourism development were mapped, the existing cooperation strategies were characterized, and investigated the influence of the cooperation actions for the current stage of product. The specific theoretical support to tourism was built on the perspective of the Theory of Population Ecology, System of Tourism and Touristic Product Life Cycle. Regarding to cooperation the theoretical foundation addressed issues of strategy, New Forms and Collective Efficiency. The survey consisted of a causal descriptive study, using a case study. We used the qualitative and quantitative methodological approaches, and data collected by consulting of secondary data and semistructured interviews with twelve staff working in tourism in Natal. Results showed that the life cycle graph of product 'Coastal Cities of Natal is moving from one stage of growth to a stage of maturity, with a primary upward trend and with crises that are up over the graph. They have been mapped six of tourism development projects of relevance to the product: The Politics of Mega Projects, PRODETUR/NE, Municipalization National Program of Tourism, Regionalization Program, Urbanization Project Beach do Meio and Actions for the Promotion of Destiny. They have been identified sixty-four participating players in process of tourism development, which twenty were considered relevant to the respondents. The main strategies identified for cooperation were the consortium, collective strategy and clusters. Results indicated that co-operation strategies were adopted so that the benefits were obtained at the collective level, dedicated to the strengthening of Natal Destiny and its products. The main reasons were the need of cooperative marketing, international market entry and actions inducing the state. Finally, it was concluded that strategies for cooperation related to product life cycle 'Coastal Cities of Natal' as that work in the consolidation of projects for development of tourism, when the efficiency of collective action is achieved

An important aspect of sustainability is to maintain biodiversity and ecosystem functioning while improving human well-being. For this, the ecosystem service (ES) approach has the potential to bridge the still existing gap between ecological management and social development, especially by focusing on trade-offs and synergies between ES and between their beneficiaries. Several frameworks have been proposed to account for trade-offs and synergies between ES, and between ES and other components of social-ecological systems. However, to date, insufficient explicit attention has been paid to the three facets encompassed in the ES concept, namely potential supply, demand, and use, leading to incomplete descriptions of ES interactions. We expand on previous frameworks by proposing a new influence network framework (INF) based on an explicit consideration of influence relationships between these three ES facets, biodiversity, and external driving variables. We tested its ability to provide a comprehensive view of complex social-ecological interactions around ES through a consultative process focused on environmental management in the French Alps. We synthetized the interactions mentioned during this consultative process and grouped variables according to their overall propensity to influence or be influenced by the system. The resulting directed sequence of influences distinguished between: (1) mostly influential variables (dynamic social variables and ecological state variables), (2) target variables (provisioning and cultural services), and (3) mostly impacted variables (regulating services and biodiversity parameters). We discussed possible reasons for the discrepancies between actual and perceived influences and proposed options to overcome them. We demonstrated that the INF holds the potential to deliver collective assessments of ES relations by: (1) including ecological as well as social aspects, (2) providing opportunities for colearning processes between stakeholder groups, and (3) supporting communication about complex social-ecological systems and consequences for environmental management.

Cette recherche vise, dans un premier temps, à colliger les informations existantes sur l’histoire de la corderie du quartier Saint-Sauveur qui passa au feu en 1866 dans un seul document tout en le bonifiant des nouveaux éléments trouvés. Puis, dans un deuxième temps, élaborer diverses activités artistiques thématiques inspirées de son histoire afin de réaliser une œuvre collective grâce à la participation d’aînés fréquentant le Centre de jour du Centre d’hébergement Notre-Dame-de-Lourdes, centre directement situé sur le site où la corderie avait été construite. Enfin, la recherche vise aussi à découvrir quelles sont les retombées pour ces aînés impliqués dans le processus de création. La recherche s’inscrit dans une perspective herméneutique puisque la question de signification et de sens en est le cœur. Que ce soit selon l’approche de Heidegger, de Gadamer, de Dilthey, de Ricœur ou celle de Grondin, chacune des avenues que ces auteurs proposent sont des pistes de compréhension. Les notions de textile, de trace, de mémoire et d’histoire contribuent aussi à éclairer et à analyser les réponses au questionnement qui sous-tend cette recherche. Les résultats obtenus permettent d’en connaître davantage sur le développement de la partie sud-est du quartier Saint-Sauveur au XIXe siècle, développement étroitement relié à la construction de navires à voiles, vaste industrie qui participa à l’essor de la ville de Québec à la même époque. Les résultats permettent aussi de comprendre ce que les thèmes inspirés de l’histoire de la corderie représentent pour les aînés participant à la création et aident également à découvrir ce que les participants ont pu retirer d’une telle expérience et ce, pour l’ensemble du processus. Mots clés : Corderie – quartier Saint-Sauveur – herméneutique – aîné – œuvre collective – textile.

Ce travail s’inscrit dans le champ des recherches concernant les pratiques inclusives en milieu scolaire ordinaire dans l’enseignement primaire. En France, le système éducatif propose de scolariser les élèves à besoins éducatifs particuliers soit en classe ordinaire, soit en classe spécialisée, bien que les gouvernements valorisent l’accueil en milieu ordinaire depuis la loi de 2005. Or, ceci questionne les pratiques des acteurs de l’école sur la prise en charge de ces élèves. Partant des travaux montrant que les enseignants utilisant l’évaluation formative gèrent mieux la diversité des élèves, nous étudions ici dans quelle mesure cette fonction de l’évaluation aiderait les élèves présentant des besoins éducatifs particuliers à acquérir des connaissances grâce aux feedbacks émis lors d’évaluations orales et de corrections collectives. L’analyse des données recueillies à l’aide d’entretiensavec des enseignants et d’observations d’élèves fait ressortir les attitudes des acteurs, les interactions et les régulations. (DIPF/Orig.)

Abstract. WikiRate is a Collective Awareness Platform for Sustainability and Social Innovation (CAPS) project with the aim of \crowdsourcing better companies" through analysis of their Environmental Social and Governance (ESG) performance. Research to inform the design of the platform involved surveying the current corporate ESG information landscape, and identifying ways in which an open approach and peer production ethos could be e ffectively mobilised to improve this landscape's fertility. The key requirement identi ed is for an open public repository of data tracking companies' ESG performance. Corporate Social Responsibility reporting is conducted in public, but there are barriers to accessing the information in a standardised analysable format. Analyses of and ratings built upon this data can exert power over companies' behaviour in certain circumstances, but the public at large have no access to the data or the most infuential ratings that utilise it. WikiRate aims to build an open repository for this data along with tools for analysis, to increase public demand for the data, allow a broader range of stakeholders to participate in its interpretation, and in turn drive companies to behave in a more ethical manner. This paper describes the quantitative Metrics system that has been designed to meet those objectives and some early examples of its use.

Background: Over the last few decades, the prevalence of young adults with disabilities (YAD) has steadily risen as a result of advances in medicine, clinical treatment, and biomedical technologythat enhanced their survival into adulthood. Despite investments in services, family supports, and insurance, they experience poor health status and barriers to successful transition into adulthood. Objectives: We investigated the collective roles of multi-faceted factors at intrapersonal, interpersonal and community levels within the social ecological framework on health related outcome including self-rated health (SRH) of YAD. The three specific aims are: 1) to examine sociodemographic differences and health insurance coverage in adolescence; 2) to investigate the role of social skills in relationships with family and peers developed in adolescence; and 3) to collectively explore the association of sociodemographic characteristics, social skills, and community participation in adolescence on SRH. Methods: Using longitudinal data (N=5,020) from the National Longitudinal Transition Study (NLTS2), we conducted multivariate logistic regression analyses to understand the association between insurance status as well as social skills in adolescence and YAD’s health related outcomes. Structural equation modeling (SEM) assessed the confluence of multi-faceted factors from the social ecological model that link to health in early adulthood. Results: Compared with YAD who had private insurance, YAD who had public health insurance in adolescence are at higher odds of experiencing poorer health related outcomes in self-rated health [adjusted odds ratio (aOR=2.89, 95% confidence interval (CI): 1.16, 7.23), problems with health (aOR=2.60, 95%CI: 1.26, 5.35), and missing social activities due to health problems (aOR=2.86, 95%CI: 1.39, 5.85). At the interpersonal level, overall social skills developed through relationship with family and peers in adolescence do not appear to have association with health related outcomes in early adulthood. Finally, at the community level, community participation in adolescence does not have an association with SRH in early adulthood. Conclusions: Having public health insurance coverage does not equate to good health. YAD need additional supports to achieve positive health outcomes. The findings in social skills and community participation suggest other potential factors may be at play for health related outcomes for YAD and the need for further investigation.

A fundamental problem in biology is understanding how and why things group together. Collective behavior is observed on all organismic levels - from cells and slime molds, to swarms of insects, flocks of birds, and schooling fish, and in mammals, including humans. The long-term goal of this research is to understand the functions and mechanisms underlying collective behavior in groups. This dissertation focuses on shoaling (aggregating) fish. Shoaling behaviors in fish confer foraging and anti-predator benefits through social cues from other individuals in the group. However, it is not fully understood what information individuals receive from one another or how this information is propagated throughout a group. It is also not fully understood how the environmental conditions and perturbations affect group behaviors. The specific research objective of this dissertation is to gain a better understanding of how certain social and environmental factors affect group behaviors in fish. I focus on two ecologically relevant decision-making behaviors: (i) rheotaxis, or orientation with respect to a flow, and (ii) startle response, a rapid response to a perceived threat. By integrating behavioral and engineering paradigms, I detail specifics of behavior in giant danio Devario aequipinnatus (McClelland 1893), and numerically analyze mathematical models that may be extended to group behavior for fish in general, and potentially other groups of animals as well. These models that predict behavior data, as well as generate additional, testable hypotheses. One of the primary goals of neuroethology is to study an organism's behavior in the context of evolution and ecology. Here, I focus on studying ecologically relevant behaviors in giant danio in order to better understand collective behavior in fish. The experiments in this dissertation provide contributions to fish ecology, collective behavior, and biologically-inspired robotics.

My thesis consists of three essays that investigate strategic interactions between individuals engaging in risky collective action in uncertain environments. The first essay analyzes a broad class of incomplete information coordination games with a wide range of applications in economics and politics. The second essay draws from the general model developed in the first essay to study decisions by individuals of whether to engage in protest/revolution/coup/strike. The final essay explicitly integrates state response to the analysis. The first essay, Coordination Games with Strategic Delegation of Pivotality, exhaustively analyzes a class of binary action, two-player coordination games in which players receive stochastic payoffs only if both players take a ``stochastic-coordination action''. Players receive conditionally-independent noisy private signals about the normally distributed stochastic payoffs. With this structure, each player can exploit the information contained in the other player's action only when he takes the “pivotalizing action”. This feature has two consequences: (1) When the fear of miscoordination is not too large, in order to utilize the other player's information, each player takes the “pivotalizing action” more often than he would based solely on his private information, and (2) best responses feature both strategic complementarities and strategic substitutes, implying that the game is not supermodular nor a typical global game. This class of games has applications in a wide range of economic and political phenomena, including war and peace, protest/revolution/coup/ strike, interest groups lobbying, international trade, and adoption of a new technology. My second essay, Collective Action with Uncertain Payoffs, studies the decision problem of citizens who must decide whether to submit to the status quo or mount a revolution. If they coordinate, they can overthrow the status quo. Otherwise, the status quo is preserved and participants in a failed revolution are punished. Citizens face two types of uncertainty. (a) non-strategic: they are uncertain about the relative payoffs of the status quo and revolution, (b) strategic: they are uncertain about each other's assessments of the relative payoff. I draw on the existing literature and historical evidence to argue that the uncertainty in the payoffs of status quo and revolution is intrinsic in politics. Several counter-intuitive findings emerge: (1) Better communication between citizens can lower the likelihood of revolution. In fact, when the punishment for failed protest is not too harsh and citizens' private knowledge is accurate, then further communication reduces incentives to revolt. (2) Increasing strategic uncertainty can increase the likelihood of revolution attempts, and even the likelihood of successful revolution. In particular, revolt may be more likely when citizens privately obtain information than when they receive information from a common media source. (3) Two dilemmas arise concerning the intensity and frequency of punishment (repression), and the frequency of protest. Punishment Dilemma 1: harsher punishments may increase the probability that punishment is materialized. That is, as the state increases the punishment for dissent, it might also have to punish more dissidents. It is only when the punishment is sufficiently harsh, that harsher punishment reduces the frequency of its application. Punishment Dilemma 1 leads to Punishment Dilemma 2: the frequencies of repression and protest can be positively or negatively correlated depending on the intensity of repression. My third essay, The Repression Puzzle, investigates the relationship between the intensity of grievances and the likelihood of repression. First, I make the observation that the occurrence of state repression is a puzzle. If repression is to succeed, dissidents should not rebel. If it is to fail, the state should concede in order to save the costs of unsuccessful repression. I then propose an explanation for the “repression puzzle” that hinges on information asymmetries between the state and dissidents about the costs of repression to the state, and hence the likelihood of its application by the state. I present a formal model that combines the insights of grievance-based and political process theories to investigate the consequences of this information asymmetry for the dissidents' contentious actions and for the relationship between the magnitude of grievances (formulated here as the extent of inequality) and the likelihood of repression. The main contribution of the paper is to show that this relationship is non-monotone. That is, as the magnitude of grievances increases, the likelihood of repression might decrease. I investigate the relationship between inequality and the likelihood of repression in all country-years from 1981 to 1999. To mitigate specification problem, I estimate the probability of repression using a generalized additive model with thin-plate splines (GAM-TPS). This technique allows for flexible relationship between inequality, the proxy for the costs of repression and revolutions (income per capita), and the likelihood of repression. The empirical evidence support my prediction that the relationship between the magnitude of grievances and the likelihood of repression is non-monotone.

Photosynthesis –the conversion of sunlight to chemical energy –is fundamental for supporting life on our planet. Despite its importance, the physical principles that underpin the primary steps of photosynthesis, from photon absorption to electronic charge separation, remain to be understood in full. Electronic coherence within tightly-packed light-harvesting (LH) units or within individual reaction centers (RCs) has been recognized as an important ingredient for a complete understanding of the excitation energy transfer (EET) dynamics. However, the electronic coherence across units –RC and LH or LH and LH –has been consistently neglected as it does not play a significant role during these relatively slow transfer processes. Here, we turn our attention to the absorption process, which, as we will show, has a much shorter built-in timescale. We demonstrate that the- often overlooked- spatially extended but short-lived excitonic delocalization plays a relevant role in general photosynthetic systems. Most strikingly, we find that absorption intensity is, quite generally, redistributed from LH units to the RC, increasing the number of excitations which can effect charge separation without further transfer steps. A biomemetic nano-system is proposed which is predicted to funnel excitation to the RC-analogue, and hence is the first step towards exploiting these new design principles for efficient artificial light-harvesting.

The WorldFish Center has been collaborating with its partners (AWF and WWF) in the Maringa-Lopori-Wamba (MLW) and the Lac Tele-Lac Ntomba (LTL) Landscapes to develop participatory monitoring systems for aquatic ecosystems. This requires rigorous data collection regarding fishing effort and catch, and the establishment of community partnerships; enabling WorldFish Center researchers to understand and counteract the institutional legacies of previous NGO interventions. In the MLW, fisherfolk livelihoods are severely limited due to their extreme isolation from markets and government services. However, fisherfolk have some experience dealing with natural resource conservation or extraction entities as well as humanitarian agencies. Their history has left them slightly skeptical but reasonably willing to collaborate with incoming NGOs. Around Lac Ntomba, fisherfolk have had more extensive interactions with conservation and humanitarian NGOs, but despite their proximity to the Congo River, they appear to have very limited access to distant markets. As past benefits from NGO activities have been captured by local village elites many fishers are highly skeptical and even antagonistic toward NGOs in general, and see little benefits from collaborating with each other or NGOs. Similarly to the MLW and Lac Ntomba, Lac Maï-Ndombe fisherfolk were disillusioned by past NGO activities. However, in this area levels of fish catch are greater than in the other watersheds, and many fishers make regular trips to major markets in Kinshasa, Kikwit and Tchikapa. Consequently, while there are significant divisions to be addressed in Lac Maï-Ndombe, fisherfolk in general are more interested in exploring options for improving livelihoods. In order to overcome these hurdles, the WorldFish Center has introduced an integrated research-extension approach in its interactions with these communities. The teams conducted demonstrations of technological innovations that could significantly improve on present post-harvest fish processing practices, in particular: a solar fish drying tent and a fish smoking barrel.

Online advertising has been growing rapidly since the mid-90s. In recent years, online advertising has become as relevant as an advertising medium as print and television are. However, despite the growth, the generally held consensus is that consumers are not interested in online advertisements. The arrival of online ad blocking tools has offered consumers a very effective way to avoid and block online advertisements. Although these tools have now been around for several years and the most popular software’s have hundreds of millions of active users, the phenomenon of ad blocking has gathered surprisingly little attention from academic marketing research. For this reason, ad blocking was chosen as the topic of this thesis study. The researcher was particularly interested in the reasons behind the usage of online ad blocking tools. The object of the empirical part of this study is to provide new and valid information regarding the reasons behind the usage of online ad blocking tools. The empirical research of this study consisted of a survey study that mixed both quantitative and qualitative elements. Although the sample size of the study was fairly limited, the study provided useful answers to individual research questions and provided new knowledge regarding the reasons behind the usage of online ad blocking and the phenomenon of ad blocking as a whole. The study provides further evidence that consumers are aware of online ad blocking tools and a significant portion of them are interested in using them. This study indicates that many of the consumers who do not have previous knowledge of these tools would actually be interested in them. The reason for the usage of online ad blocking tools varies from institutional reasons to instrumental reason, such as poor quality of the online advertisements. However, there were participants who were not interested in the usage of online ad blocking tools, and some of them reported to find online advertising useful. There also seems to be a concern among some consumers that online ad blocking will have a negative effect on online content in the future if the ad blocking will keep growing as a phenomenon. This certainly can be the case, and it is very interesting to see how the development of online ad blocking will shape the online advertising, how the advertising industry will respond to the growth of online ad blocking and how will the consumers respond to these changes.
