In the past decades, social-ecological systems (SESs) worldwide have undergone dramatic transformations with often detrimental consequences for livelihoods. Although resilience thinking offers promising conceptual frameworks to understand SES transformations, empirical resilience assessments of real-world SESs are still rare because SES complexity requires integrating knowledge, theories, and approaches from different disciplines. Taking up this challenge, we empirically assess the resilience of a South African pastoral SES to drought using various methods from natural and social sciences. In the ecological subsystem, we analyze rangelands’ ability to buffer drought effects on forage provision, using soil and vegetation indicators. In the social subsystem, we assess households’ and communities’ capacities to mitigate drought effects, applying agronomic and institutional indicators and benchmarking against practices and institutions in traditional pastoral SESs. Our results indicate that a decoupling of livelihoods from livestock-generated income was initiated by government interventions in the 1930s. In the post-apartheid phase, minimum-input strategies of herd management were adopted, leading to a recovery of rangeland vegetation due to unintentionally reduced stocking densities. Because current livelihood security is mainly based on external monetary resources (pensions, child grants, and disability grants), household resilience to drought is higher than in historical phases. Our study is one of the first to use a truly multidisciplinary resilience assessment. Conflicting results from partial assessments underline that measuring narrow indicator sets may impede a deeper understanding of SES transformations. The results also imply that the resilience of contemporary, open SESs cannot be explained by an inward-looking approach because essential connections and drivers at other scales have become relevant in the globalized world. Our study thus has helped to identify pitfalls in empirical resilience assessment and to improve the conceptualization of SES dynamics.

We explore the impact of “game changers” on the dynamics of innovation over time in three problem domains, that of wilderness protection, women’s rights, and assimilation of indigenous children in Canada. Taking a specifically historical and cross-scale approach, we look at one social innovation in each problem domain. We explore the origins and history of the development of the National Parks in the USA, the legalization of contraception in the USA and Canada, and the residential school system in Canada. Based on a comparison of these cases, we identify three kinds of game changers, those that catalyze social innovation, which we define as “seminal,” those that disrupt the continuity of social innovation, which we label exogenous shocks, and those that provide opportunities for novel combinations and recombinations, which we label as endogamous game changers.

Introdução e objetivo: Atualmente as Instituições Particulares de Solidariedade Social deparam-se com mudanças de caracter social, económico e legislativo, que têm afetado o seu funcionamento e financiamento. Pelo que, impõe-se às suas direções responder às necessidades sociais com maior responsabilidade e eficiência num contexto de maior escassez de recursos. Neste sentido, o presente estudo tem como objetivo compreender o modo como as Instituições Particulares de Solidariedade Social tomam decisões, ao nível do financiamento, para um funcionamento eficiente das mesmas. Metodologia: Optou-se por realizar estudos de caso com uma amostra constituída por quatro Instituições Particulares de Solidariedade Social. A recolha de dados foi feita através de entrevistas semiestruturadas e análise documental. O tratamento de dados foi feito através de análise de conteúdo e com recurso ao software QRS Nvivo versão 10. Resultados: Os principais resultados indicam que: a) as necessidades sociais influenciam decisões de aumento e diminuição da capacidade de respostas das instituições; b) o sistema legal influencia a perpetuação de intervenções de caracter institucional; c) a conjuntura económica influencia a pressão sobre o preço da comparticipação familiar e o aumento da concorrência entre instituições; d) a escassez de recursos constitui-se como denominador comum entre instituições, influenciando decisões de investimento que assumem o financiamento público como um facto consumado; e) as práticas de liderança e gestão desenvolvidas por direções com elementos que têm conhecimentos na área financeira são mais propensas a assumir o risco e a aumentar a complexidade operativa das instituições f) as práticas de envolvimento de stakeholders internos e externos contribuem para a aquisição de apoio na prossecução dos seus objetivos. Conclusão: As tomadas de decisão das instituições com acordos com a segurança social assemelham-se por prevalecer o desenvolvimento de respostas tipificadas, com acordo com a segurança social. Apesar disso, os resultados evidenciam a importância de práticas de liderança e gestão desenvolvidas com a presença de elementos com conhecimentos na área financeira, para o desenvolvimento de respostas tipificadas com rentabilidade económica. Salienta-se ainda que o desenvolvimento de práticas de envolvimento de stakeholders internos e externos, baseados na responsabilização e transparência, promovem o alcance de apoios para assegurar o desenvolvimento das atividades institucionais, com maior incidência na instituição sem acordos com a segurança social, mas que os mesmos não asseguram a sua eficiência económica.

This paper proposes to analyse a situation of social drama involving the Krahô Indians (classified in ethnology as belonging to Jê-Timbira group) and the Museu Paulista of the Universidade de São Paulo, which we can classify as two distinct social fields. The understanding of the drama is conveyed through an examination of each of these fields and the coming together of both on the basis of the positions taken up, within the network of relationships established during the social process, by actors representing both the Krahô field and what we may call here the academic-administrative field. A multi-sited ethnographic approach is adopted, seeking the complexity of the drama and the positions in the aforementioned network, taking into consideration institutional political projects, personal projects and personal trajectories within a historical perspective. The aim is to encourage discussion of the relationship between the formation of the historical-scientific and ethnographic museums and the practices of the anthropological discipline, as well as the social role of these institutions and the processes of signification of objects belonging to the indigenous material culture

This Masters Degree dissertation seeks to make a comparative study of internal air temperature data, simulated through the thermal computer application DesignBuilder 1.2, and data registered in loco through HOBO® Temp Data Logger, in a Social Housing Prototype (HIS), located at the Central Campus of the Federal University of Rio Grande do Norte UFRN. The prototype was designed and built seeking strategies of thermal comfort recommended for the local climate where the study was carried out, and built with panels of cellular concrete by Construtora DoisA, a collaborator of research project REPESC Rede de Pesquisa em Eficiência Energética de Sistemas Construtivos (Research Network on Energy Efficiency of Construction Systems), an integral part of Habitare program. The methodology employed carefully examined the problem, reviewed the bibliography, analyzing the major aspects related to computer simulations for thermal performance of buildings, such as climate characterization of the region under study and users thermal comfort demands. The DesignBuilder 1.2 computer application was used as a simulation tool, and theoretical alterations were carried out in the prototype, then they were compared with the parameters of thermal comfort adopted, based on the area s current technical literature. Analyses of the comparative studies were performed through graphical outputs for a better understanding of air temperature amplitudes and thermal comfort conditions. The data used for the characterization of external air temperature were obtained from the Test Reference Year (TRY), defined for the study area (Natal-RN). Thus the author also performed comparative studies for TRY data registered in the years 2006, 2007 and 2008, at weather station Davis Precision Station, located at the Instituto Nacional de Pesquisas Espaciais INPE-CRN (National Institute of Space Research), in a neighboring area of UFRN s Central Campus. The conclusions observed from the comparative studies performed among computer simulations, and the local records obtained from the studied prototype, point out that the simulations performed in naturally ventilated buildings is quite a complex task, due to the applications limitations, mainly owed to the complexity of air flow phenomena, the influence of comfort conditions in the surrounding areas and climate records. Lastly, regarding the use of the application DesignBuilder 1.2 in the present study, one may conclude that it is a good tool for computer simulations. However, it needs some adjustments to improve reliability in its use. There is a need for continued research, considering the dedication of users to the prototype, as well as the thermal charges of the equipment, in order to check sensitivity

Children develop in a sea of reciprocal social interaction, but their brain development is predominately studied in non-interactive contexts (e.g., viewing photographs of faces). This dissertation investigated how the developing brain supports social interaction. Specifically, novel paradigms were used to target two facets of social experience—social communication and social motivation—across three studies in children and adults. In Study 1, adults listened to short vignettes—which contained no social information—that they believed to be either prerecorded or presented over an audio-feed by a live social partner. Simply believing that speech was from a live social partner increased activation in the brain’s mentalizing network—a network involved in thinking about others’ thoughts. Study 2 extended this paradigm to middle childhood, a time of increasing social competence and social network complexity, as well as structural and functional social brain development. Results showed that, as in adults, regions of the mentalizing network were engaged by live speech. Taken together, these findings indicate that the mentalizing network may support the processing of interactive communicative cues across development. Given this established importance of social-interactive context, Study 3 examined children’s social motivation when they believed they were engaged in a computer-based chat with a peer. Children initiated interaction via sharing information about their likes and hobbies and received responses from the peer. Compared to a non-social control, in which children chatted with a computer, peer interaction increased activation in mentalizing regions and reward circuitry. Further, within mentalizing regions, responsivity to the peer increased with age. Thus, across all three studies, social cognitive regions associated with mentalizing supported real-time social interaction. In contrast, the specific social context appeared to influence both reward circuitry involvement and age-related changes in neural activity. Future studies should continue to examine how the brain supports interaction across varied real-world social contexts. In addition to illuminating typical development, understanding the neural bases of interaction will offer insight into social disabilities such as autism, where social difficulties are often most acute in interactive situations. Ultimately, to best capture human experience, social neuroscience ought to be embedded in the social world.

The farm-gate value of extensive beef production from the northern Gulf region of Queensland, Australia, is ~$150 million annually. Poor profitability and declining equity are common issues for most beef businesses in the region. The beef industry relies primarily on native pasture systems and studies continue to report a decline in the condition and productivity of important land types in the region. Governments and Natural Resource Management groups are investing significant resources to restore landscape health and productivity. Fundamental community expectations also include broader environmental outcomes such as reducing beef industry greenhouse gas emissions. Whole-of-business analysis results are presented from 18 extensive beef businesses (producers) to highlight the complex social and economic drivers of management decisions that impact on the natural resource and environment. Business analysis activities also focussed on improving enterprise performance. Profitability, herd performance and greenhouse emission benchmarks are documented and discussed.

Over the last decade, success of social networks has significantly reshaped how people consume information. Recommendation of contents based on user profiles is well-received. However, as users become dominantly mobile, little is done to consider the impacts of the wireless environment, especially the capacity constraints and changing channel. In this dissertation, we investigate a centralized wireless content delivery system, aiming to optimize overall user experience given the capacity constraints of the wireless networks, by deciding what contents to deliver, when and how. We propose a scheduling framework that incorporates content-based reward and deliverability. Our approach utilizes the broadcast nature of wireless communication and social nature of content, by multicasting and precaching. Results indicate this novel joint optimization approach outperforms existing layered systems that separate recommendation and delivery, especially when the wireless network is operating at maximum capacity. Utilizing limited number of transmission modes, we significantly reduce the complexity of the optimization. We also introduce the design of a hybrid system to handle transmissions for both system recommended contents ('push') and active user requests ('pull'). Further, we extend the joint optimization framework to the wireless infrastructure with multiple base stations. The problem becomes much harder in that there are many more system configurations, including but not limited to power allocation and how resources are shared among the base stations ('out-of-band' in which base stations transmit with dedicated spectrum resources, thus no interference; and 'in-band' in which they share the spectrum and need to mitigate interference). We propose a scalable two-phase scheduling framework: 1) each base station obtains delivery decisions and resource allocation individually; 2) the system consolidates the decisions and allocations, reducing redundant transmissions. Additionally, if the social network applications could provide the predictions of how the social contents disseminate, the wireless networks could schedule the transmissions accordingly and significantly improve the dissemination performance by reducing the delivery delay. We propose a novel method utilizing: 1) hybrid systems to handle active disseminating requests; and 2) predictions of dissemination dynamics from the social network applications. This method could mitigate the performance degradation for content dissemination due to wireless delivery delay. Results indicate that our proposed system design is both efficient and easy to implement.

This study was a critical investigation of the configuration of discourse on work in the Brazilian criminal legal discourse. We problematized the discourse of an alleged reintegrative social function proposed by the criminal legal system and analyzed the role of such discourse in the core of disciplinary power strategies that impose on individuals the honest worker condition as a major criterion for their rehabilitation and return to society as citizens. This critique is our starting point to build the argument that discourse on work as it appears in current criminal legal texts operates more as a criminalization index of those who do not have a lawful occupation than a guarantee of legitimate social transit for convicts and recognition of their dignity. For this purpose, we used as corpus the main sources of Law, namely the Federal Constitution of 1988, the Penal Code, the Penal Execution Law, the Brazilian criminal doctrine and an extensive, more recent penal jurisprudence with regard to techniques of resocialization through work. This critical line enabled us to recognize complexity and plurality of discourses - antagonistic, at times - that build the world of work as portrayed in legal texts. We also sought reference in the discussion on the centrality of work as a formative category of the social being as well as theories that defend the non-centrality of work. Throughout our investigation, we sough to question the very condition of such centrality and to understand the ways in which it was possible to produce a legitimating discourse on work as a model of emancipatory social conduct defended and demanded by the Brazilian punitive system. In a context of precariousness, unemployment and flexibilization of the world of work in contemporary society, convicts hardly ever succeed to resume the identity of honest, hard-working citizens - and no longer offenders. In this context, we also questioned the formulation of a discourse that speaks about human labor as the essence of man and criticizes the Marxist vision that is based on work centrality, and we approached the concept of Michel Foucault, our theoretician of reference, who understands work more as a mechanism of power that promotes the individuals’ submission and adaptation to a goods-producing society than the natural activity of man. We ascribe our study to the field of questions that tackle the political conception of the body as subject to labor imposed as productive and political force. It is about the issue of political technology of individuals, a technology of power, as named by the French author. The intended analysis has not dismissed the material existence of labor relations but sought to discuss the validity of a discourse that considers work the main resource for convict rehabilitation and index for the recognition of dignity and honesty. The Foucauldian discourse analysis was the foundation for the investigation of our object, especially if we understand discourses as social practices with power to institute knowledge and produce truths.

The organizations are characterized as dynamic spaces, they are being revisited and redefined, because they constitute structural human spaces and new vain outlines won expression. As it begins, of the non consensus in its conception, it is explicit the complexity degree that is identified in the plurality and diversity, brought by the people that compose them, characterizing it as accomplishment space, of happiness and also of conflict, of relationships of power and organizational limits and from birth and burial of faiths, values, norms, symbols, knowledge and rituals, therefore, deeply human. In that way, to know the administration of the organization is preponderant condition for the format of the human relationships to be delineated in its living. Like this the work makes an option in knowing the social administration, this work tries to know and analyze the values and beginnings of the social administration; revealling characteristics and specificities of the organizational performance of UNIPOP that contribute to the formation of the conception of Social Administration, it tends as source of the information the managers of the institution; to identify the formative values of UNIPOP that contribute to the youths' partner-political action in the community, tends for reference the current students of the organization and last to evaluate values structurates and supporting that interconnection between the organizational Administration, formation youth's program, participation and autonomy and attendance, starting from the existences gained by the exits, of that program. This way, the research will be qualitative, looking for understanding starting from their documents, the existence of those values
