Canal do Valo Grande: Governança das águas estuarinas na perspectiva da aprendizagem social / Valo Grande Channel: estuarine waters governance in the social learning perspective

Souza, Eliel Pereira de 27 April 2012 (has links)
A publicação da lei 9.433 de 1997, que institucionaliza a Política Nacional de Recursos Hídricos no Brasil, abriu a perspectiva de uma gestão integrada, participativa e descentralizada dos recursos hídricos. A integração da gestão de bacias hidrográficas com a gestão da zona costeira é uma diretriz dessa política e a participação social é pressuposto para medidas de gestão mais sustentáveis e legítimas. A qualidade dos processos participativos está ligada à incorporação de diferentes atores, com perspectivas distintas em relação à bacia hidrográfica, em processos de grupo que permitam reflexão e aprendizado, sobre o próprio grupo e sobre o ambiente natural e institucional da bacia. O presente trabalho é um estudo de caso sobre a gestão da bacia do rio Ribeira de Iguape, no litoral sul de São Paulo. Na porção terminal desse rio, uma obra hidráulica construída no século XIX, conhecida como Valo Grande, retificou seu curso, desestabilizando o sistema estuarino adjacente pelo aporte de água e sedimentos em região abrigada. Desde a década de 70, houve uma série de ações governamentais no sentido de recuperara essa região do estuário, o que gerou tensão e conflito com os atores a montante da bacia. Em resposta, o assunto foi debatido e negociado em diferentes fóruns criados a partir da década de 80. O presente trabalho analisa o processo decisório sobre o canal, buscando identificar elementos que favorecem ou inibem a transformação da participação em aprendizagem social. Os resultados revelam que a aprendizagem social não é um processo espontâneo, e, apesar da forte interdependência entre os atores envolvidos, espaços de convergência e consenso são prejudicados por fatores como a falta de liderança pró-ativa, representação desproporcional dos atores, ausência de redes de cooperação e coalizões, além da falta de implementação de medidas negociadas. / The launch of the Law 9.433 of 1997, wich institutionalizes the National Policy of Water Resources, opened the prospect of an integrated, participatory and decentralized management of the water resources. The integration of the watershed management with the management of the coastal zone is a guideline of this policy and social participation is prerequisite for more sustainable and legitimate. The quality of participatory process is linked to the incorporation of different actors, with distinctive perspectives in relation to the catchment area, in a group process that enable reflection and learning, about the own group itself and about the natural and institutional framework of the basin. The present study is a case study on the management of river basin of Ribeira de Iguape, on the southern coast of São Paulo State. In the terminal part of this river, a hydraulic work was built in the nineteenth century, known as Valo Grande, rectify its course, destabilizing the adjacent estuary system by the input of water and sediments in a sheltered area. Since the 70s, there was a series of government in order to recover this region of estuary, wich created tension and conflict with the upstream actors of the basin. In response, the matter was discussed and negotiated in different decision-makers forums created since the 80s. The present work examines the decision process on the channel, in order to identify factors that promote or inhibit the transformation of participation in social learning. The results show that the social learning is not a spontaneous process, and despite the strong interdependency among the actors envolved, areas of convergence and consensus are affected by aspects like the lack of a proactive leadership, disproportionate representation of actors, lack of networks of cooperation and coalition, and the lack of implementation of negotiated measures.

Sequential games under positional uncertainty

Gibson, Christopher Daniel January 2019 (has links)
This dissertation focuses on sequential games of imperfect information. I study settings in which not only do agents face imperfect information in the traditional sense of not possessing all payoff-relevant information, but they also face uncertainty about their position of movement in the sequence. I have utilized this framework to study financial investment decisions by individuals, production decisions by firms, and implications on information aggregation in observational learning. In order to study production decisions by firms I utilize a Stackelberg oligopoly model with a stochastic consumer demand. In this setting firms do not know their position of movement, and as a result of the stochastic demand they cannot infer from the prevailing price if another firm has yet entered the market. I find that as a result of uncertainty firms produce a higher quantity than they otherwise would have, resulting in a more competitive outcome. In fact, as the number of firms in the market increases, with positional uncertainty the equilibrium quantity actually exceeds the perfectly competitive quantity. I then investigate the impact of positional uncertainty when agents must choose levels of investment in a financial asset. Investors receive a signal about the value of the asset but are not necessarily aware of their position in the sequence of investors. As a result, they are unsure to what extent the signal they receive represents profit-relevant information, or if the signal is “stale” in the sense that the information has been incorporated into the price by other investors. This results in more cautious levels of investment, and an asset price that does not represent the true underlying value. To study the behavioral aspects of financial investment, I introduce in this model a notion of confidence. While much work in the area of behavioral finance has studied the role of confidence over the accuracy of information, my interest is in confidence over the timing of information. I define an agent as overconfident if they believe they are more likely to have received the signal earlier than other agents, and are thus more likely to be early investors. The effect of overconfidence can overwhelm the cautious nature of positionally uncertain investors, even potentially leading to an overreaction to information. This effect can explain overvaluation of assets and volatility of prices in response to information. In a model of observational learning, limited information about the history of actions slows the integration of information. However, I show that in the limit, even in the presence of limited histories complete learning occurs. In the environment of limited access to historical information I introduce uncertainty over position of action. This uncertainty even further dampens the process of learning from a welfare standpoint, but as the number of agents grows large complete learning still obtains in the limit for all levels of uncertainty. The common finding in all these settings is that uncertainty about the order of action causes agents to be cautious about exploiting profitable opportunities. In the case of oligopoly this leads to more competitive outcomes, whereas in the cases of investment and social learning uncertainty leads to less effective information aggregation.

Determinants of Social Disorganization as Predictors of Illicit Drug Use During Recessionary Years

Westmoreland, Daniel Kirk 01 January 2015 (has links)
Research suggests evidence of an association between sociodemographic determinants and illicit drug use. However, these data do not take into consideration the effect an economic obstacle, such as a recession, could have on an individual's urge to cope with this stressful period with illicit drugs. Furthermore, there is no research to suggest how clinicians and/or treatment institutions can forecast whether the use of monetary resources will be sustainable due to private and/or governmental fund reductions during an economic recession. Based on theories of social learning and social disorganization within an ecological framework, this study employed a quantitative trend analysis to explore the impact the 2007-2009 economic recession had on illicit drug use throughout the United States. A sample of respondents from the Substance Abuse and Mental Health Data Archive from 2006 to 2010 surveys was used to run the statistical analysis. Based on the analyses, age and gender (covariates) and all variables (social disorganization and Gross Domestic Product) were found to be significant predictors of illicit drug use. Although methamphetamine was not significant for prevalence over time, total drug use, cocaine, and heroin were prevalent over time based on predictors. These findings suggest local, state, and federal policies regarding the prosecution and imprisonment of nonviolent and minor drug offenders should be reprioritized towards the rehabilitation of addicts while enforcing firmer laws upon the most disruptive and severe aspects of the drug trade in order to promote a genuine positive change towards social organization.

Deliberating Across Difference: Bringing Social Learning into the Theory and Practice of Deliberative Democracy in the Case of Turkey

Kanra, Bora, bora.kanra@anu.edu.au January 2005 (has links)
This thesis will argue that one of the main challenges for deliberative democracy is the lack of attention paid to the different modes of deliberative practices. The theories of deliberative democracy often treat deliberation as a decision-making process. Yet, I would argue that this approach fails to appreciate the full benefits of deliberation because it ignores the fundamental role that the social learning phase of deliberation plays in reconciling differences. Hence I argue for a deliberative framework in which social learning and decision-making moments of deliberation are analytically differentiated so that the resources of social learning are freed from the pressures of decision-making procedures and are therefore no longer subordinated to the terms of decision-making.¶ This is particularly important for countries such as Turkey where divisions cut deep across society. A case study examines the discourses of the Turkish public sphere regarding Islam, democracy and secularism to identify the kinds of discourses present in relation to the topic in question. By analysing the types of discourses through Q methodology the study reveals points of convergence and divergence between discourses, hence provides significant insight into how deliberation oriented to social learning can play a substantive role in reconciling differences between sharply divided groups.

"All the time learning... three months are equal to one year": Second language learning in a target-language community.

Sayin, Saffet. January 2009 (has links)
Australia hosts thousands of English language learners every year and one of the reasons learners give for this is their belief that living in the target language community naturally avails them of more language learning opportunities than are available in their homelands. In fact, learners actually learn faster and more effectively compared to the limited gains in their respective countries. Believing that the target language community has a strong role in language learning, this research focuses on the factors and opportunities which enable students to develop their language skills in informal settings outside the school. Due to the vast scope of the research area, six different types of data collection methods have been used so that a wider spectrum in SLA could be investigated. These include an exploration of learner beliefs about their language learning experiences and a study of authentic social activities and linguistic engagements within those activities. The outcome of this research suggests that language learning is not first initiated “in the head”, but starts with the social activities in which learners participate and the qualities of the linguistic challenges and opportunities within these activities. The research draws on sociocultural theory (Vygotsky 1962, 1978), ecological approach to learning (van Lier 1999) and register theory (Halliday and Hasan 1985), and also on a range of research within second language acquisition studies. The study illustrates that language learning occurs in the context of activitybased communication experiences in authentic contexts, and the more the constant challenge and varied linguistic opportunities exist in the learner’s ecology, the more and better the chances to learn language. An overall approach to understanding independent language learning and a conceptual framework for examining informal language learning opportunities, have been developed. The study concludes with some implications for pedagogical practice in English language classrooms.

Constructing bodies: gesture, speech and representation at work in architectural design studios

Mewburn, Inger Blackford January 2009 (has links)
Previous studies of the design studio have tended to treat learning to design as a matter of learning to think in the right way, despite the recognition that material artifacts and the ability to make and manipulate them in architectural ways is important to the design process. Through the use of empirical data gathered from watching design teachers and students in action, this thesis works to discover how material things and bodies are important to the fabrication of architectural meaning and architectural subjectivity within design studios. In particular the role of gesture is highlighted as doing important work in design studio knowledge practices. / The approach taken in this thesis is to treat design activity in design studios in a ‘post-human’ way. An analytical eye is turned to how things and people perform together and are organised in various ways, using Actor network theory (ANT) as a way to orientate the investigation. The assumption drawn from ANT is that that architectural meaning, knowledge and identity can positioned as network effects, enacted into being as the design studio is ‘done’ by the various actors — including material things, such as architectural representations, and human behaviours, such as gesture. / Gesture has been largely ignored by design studio researchers, perhaps because it tends to operate below the threshold of conscious awareness. Gesture is difficult to study because the meanings of most gestures produced during conversations are spontaneous and provisional. Despite this humans seem to be good interpreters of gesture. When studied in detail, ongoing design studio activity is found to rely on the intelligibility of gesture done in ‘architectural ways’. The main site for the observation of gesture during this study was the ‘desk crit’ where teachers and students confer about work in progress. In the data gathered for this thesis gesture is found to operate with representations in three key ways: explaining and describing architectural composition, ‘sticking’ spoken meanings strategically to representations and conveying the phenomenological experience of occupying architectural space – the passing of time, quality of light, texture and movement. / Despite the fact that most of the work of the thesis centres on human behaviour, the findings about the role of gesture and representation trouble the idea of the human as being at the centre of the action, putting the bodies of teachers and students amongst a crowd of non human others who participate together in design knowledge making practices.

Social learning in the Anthropocene : Governance of natural resources in human dominated systems

Nykvist, Björn January 2012 (has links)
We live in the Anthropocene – an age where humans dominate natural systems – and there is ample evidence that our current practices degrade the capacity of natural systems to provide us with natural resources. How we, as humans, organize and learn, in communities and among state and other societal actors, constitute a decisive factor for both local management of natural resources and the functioning of the planet Earth. In other words, the outcome of learning has become a matter of governance across multiple levels. This thesis studies the role of social learning in governance of natural resources, asking the following three overarching questions: i) What are the institutional barriers limiting better environmental governance at different scales? ii) Is there a causal connection between social learning and better environmental governance? iii) What are the normative challenges with better environmental governance or social-ecological resilience being linked to the adaptive capacity of actors to learn socially? The primary method is semi-structured in-depth interviews. Papers provide results on institutional barriers such as competency traps and show how customs and current practices and collaborations limit better environmental governance. It is found that social learning might, and might not, lead to better environmental governance, and the causal connection between social learning and better environmental governance is found to be rather weak, with both variables depending on other factors. Enabling policy, a mandate to make broad assessments, or an engaged leader facilitating social learning, are examples of factors that explain the existence of both social learning and outcomes in terms of better environmental governance. It is concluded that since conditions for, and facilitation of, social learning are so important, research should focus more on what initiates social learning and how social learning can be mainstreamed across multiple levels of governance / At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Submitted: Paper 4: Submitted; Paper 5: Submitted.

Onlooking consumers' response to the information about service providers punishing violated consumers

Chiou, Jie-ru 30 July 2007 (has links)
Service providers often use various types of ¡§punishments¡¨ or ¡§penalties¡¨ to reduce the frequency of customers¡¦ violations and to balance their potential loss, but researchers does not pay much attention to ¡§customer penalties¡¨. Existing studies of customer penalties focus on the relationships between the service provider (the executor) and customers (the recipients) who violate company¡¦s policy, especially on the effects of punishment toward recipients. However, studies in ¡§organizational punishments¡¨ had enlarge the scope of research by including observers, and developed a framework for studying the effects of punishments on observers which is called ¡§a framework for understanding the social effects of organizational punishment¡¨. This study is based on customer penalties, and the researcher cites the viewpoints and theories from this framework to enlarge the scope of research in bilateral to tripartite. This study examines observers¡¦ responses, including their perception of justice, violate intension, and affective commitment to the service provider, when they obtain the information about service provider punishing a violated customer by experimental design. The result shows that social learning effect will exists if observers receive information about punishments. Observers prefer service providers whose punishments with lower severity, higher flexibility, and adequate explanations. The result also shows that perceived justice has a partial mediating effect on ¡§punishments-responses¡¨ relation.

Professional Development of Physiotherapists Working in Long-term Care

Marice, Prior 18 October 2012 (has links)
The purpose of this study is to learn about the professional development practices of physiotherapists working in long-term care homes in Ontario. A survey was created based on relevant literature and piloted for this study. The survey included both quantitative and open-ended questions. 44 Physiotherapist responded, which represents approximately 10% of physiotherapists working in long-term care in Ontario. The results indicate that physiotherapists are isolated from their physiotherapist peers and lack access to communities of practice, professional socialisation, professional culture and social regulation. Although physiotherapists’ interactions with interprofessional teams added breadth to their knowledge, these interactions did not enhance their profession-specific skills. Many physiotherapists are seeking professional community and social supports in healthcare settings outside of the long-term care context. The implications of this study are that physiotherapists, their professional associations, and their college must understand the importance of professional socialization in learning, and ensure that physiotherapists working in long-term care have access to and seek such social support. Physiotherapy service providers in long-term care should provide mentoring, support and opportunities for social learning for their clinicians. Finally, long-term care homes and the Ministry of Health and Long-term care need to ensure that policies provide a better definition of the role of physiotherapists in long-term care.
