Diplomacia transfronteriza en tiempos de revolución: el Alto Río Negro iberoamericano, 1815-1820 (Estudios)

This article studies the impacts of the independence war in the regional border of the High Negro River, taking as it’s object of analysis the existing multiples connections between the inhabitants of both sides of the imaginary boundary line. From July 1817, the independence war in Venezuela changed the coordinates: the struggles between the republican patriots and those obedient to the King (Realistas), faithful to the restoration of the Spanish monarchy of Fernando VII, managed the great border region, and influenced the political, social and local dynamics, mainly the existing cross-border relations between both, impacted the ordinary life of the local population and affected the diplomacy between the Portuguese and Spanish American authorities, those faithful to the King (Realistas) and patriots.

Cyclamen: time, sea and speciation biogeography using a temporally calibrated phylogeny

Aim The Mediterranean region is a species-rich area with a complex geographical history. Geographical barriers have been removed and restored due to sea level changes and local climatic change. Such barriers have been proposed as a plausible mechanism driving the high levels of speciation and endemism in the Mediterranean basin. This raises the fundamental question: is allopatric isolation the mechanism by which speciation occurs? This study explores the potential driving influence of palaeo-geographical events on the speciation of Cyclamen (Myrsinaceae), a group with most species endemic to the Mediterranean region. Cyclamen species have been shown experimentally to have few genetic barriers to hybridization. Location The Mediterranean region, including northern Africa, extending eastwards to the Black Sea coast. Methods A generic level molecular phylogeny of Myrsinaceae and Primulaceae is constructed, using Bayesian approximation, to produce a secondary age estimate for the stem lineage of Cyclamen. This estimate is used to calibrate temporally an infrageneric phylogeny of Cyclamen, built with nrDNA ITS, cpDNA trnL-F and cpDNA rps16 sequences. A biogeographical analysis of Cyclamen is performed using dispersal-vicariance analysis. Results The emergence of the Cyclamen stem lineage is estimated at 30.1-29.2 Ma, and the crown divergence at 12.9-12.2 Ma. The average age of Cyclamen species is 3.7 Myr. Every pair of sister species have mutually exclusive, allopatric distributions relative to each other. This pattern appears typical of divergence events throughout the evolutionary history of the genus. Main conclusions Geographical barriers, such as the varying levels of the Mediterranean Sea, are the most plausible explanation for speciation events throughout the phylogenetic history of Cyclamen. The genus demonstrates distributional patterns congruent with the temporally reticulate palaeogeography of the Mediterranean region.

Adapting to new challenges: extension theory and practice for the 21st century

Twenty first century challenges facing agriculture include climate change, threats to food security for a growing population and downward economic pressures on rural livelihoods. Addressing these challenges will require innovation in extension theory, policy and education, at a time when the dominance of the state in the provision of knowledge and information services to farmers and rural entrepreneurs continues to decline. This paper suggests that extension theory is catching up with and helping us to understand innovative extension practice, and therefore provides a platform for improving rural development policies and strategies. Innovation is now less likely to be spoken of as something to be passed on to farmers, than as a continuing process of creativity and adaptation that can be nurtured and sustained. Innovation systems and innovation platforms are concepts that recognise the multiple factors that lead to farmers’ developing, adapting and applying new ideas and the importance of linking all actors in the value chain to ensure producers can access appropriate information and advice for decision making at all stages in the production process. Concepts of social learning, group development and solidarity, social capital, collective action and empowerment all help to explain and therefore to apply more effectively group extension approaches in building confidence and sustaining innovation. A challenge facing educators is to ensure the curricula for aspiring extension professionals in our higher education institutions are regularly reviewed and keep up with current and future developments in theory, policy and practice.

Sustainable food? Teikei, co-operatives and food citizenship in Japan and the UK

This paper explores in particular how Teikei groups, as forms of Community Supported Agriculture (CSA), operate in Japan, focussing on one particular group. The paper links the Teikei approach to debates around social capital and consumer-citizenship, arguing that pre-existing consumer/citizen institutions may usefully be engaged in developing food citizenship and CSA operations. The discussion is linked to CSA and various other alternative food networks (AFNs) that have grown up in various forms in Japan, the US, the UK and elsewhere in Europe over the past thirty years or so. CSA in similar fashion to Teikei involves bringing producers and consumers closer together in terms of reconnecting the agricultural producer and consumer to aid food traceability and quality (including organic). CSA also exhibits elements of new assemblies of agricultural governance based on enhanced consumer-citizenship where consumers, to varying degrees, have a say in what and how produce is grown and how the land is managed.

Safeguarding inheritance and enhancing the resilience of orphaned young people living in child- and youth-headed households in Tanzania and Uganda

This paper explores the resilience of orphaned young people in safeguarding the physical assets (land and property) that they inherited from their parents and in sustaining their households without a co-resident adult relative. Drawing on the concept of resilience and the sustainable livelihoods framework, this paper analyses the findings of an exploratory study conducted with 15 orphaned young people heading households,18 of their siblings and 39 NGO workers and community members in Tanzania and Uganda. The research suggests that inherited land and property represent key determining factors in the formation and viability of child- and youth-headed households in both rural and urban areas. Despite experiences of stigma and marginalisation in the community, social networks were crucial in enabling young people to protect themselves and their property, in providing access to material and emotional resources and in enhancing their skills and capabilities to develop sustainable livelihoods. Support for child- and youth-headed households needs to recognise young people's agency and adopt a holistic approach to their lives that analyses the physical assets, material resources, human and social capital available to the household, as well as individual young people's wellbeing, outlook and aspirations. Alongside cash transfers and material support, youth-led collective mobilisation that is sustained over time may also help to build resilience and foster more supportive social environments that challenge property grabbing and the stigmatisation of child- and youth-headed households.

Customer service 140 characters at a time: the users’ perspective

Electronic word of mouth (eWoM) has been adopted by Internet users as a way of communicating their consumption preferences and experiences. Consumers are able to reach out to others, unknown to them, and have online conversations that can influence their behaviour. Organisations need to understand how to respond to these brand-related conversations conducted via social media. By looking through the lens of social capital, this paper contributes to social media and social capital research by studying the perceptions that 44 social media users have of companies that interact with them online. The users value social networks and support as part of their online relationships. However, several new value categories are identified when compared to previous research. Further research is required to investigate possible segmentation approaches and alternative methodological choices.

Coming to grips with 'abandoned arable' land in efforts to enhance communal grazing systems in the Eastern Cape province, South Africa

The communal lands of the Eastern Cape have been regarded as both tools and problems by policy-makers. In particular, communal lands are problematised as environmentally degraded, of suboptimum productivity and constraining economic development. The Eastern Cape Communal Lands Research Project was framed within this policy discourse with the aim of introducing legume-based pasture into ‘abandoned arable lands’. Initial results from community workshops show that the institutional arrangements for these arable lands vary widely and, with them, the capacity to utilise any new technology that may have application to them. Rather than simply draw on social capital, if a participatory research approach is to enhance the agency of the participating communites, it may need to contribute to social capital building and especially to create a dialogical space in which the matters being researched can be discussed meaningfully.

HIV-related stigma, asset inheritance and chronic poverty: vulnerability and resilience of widows and caregiving children and youth in Tanzania and Uganda

This paper develops a framework of risk and protective factors to conceptualise the relationship between HIV-related stigma, asset inheritance and chronic poverty among widows and caregiving children and youth in eastern Africa. Analysis of two qualitative studies with 85 participants in rural and urban areas of Tanzania and Uganda reveals that gendered and generational inequalities and stigmatisation sometimes led to property grabbing and chronic poverty. Human and social capital and preventative measures however may help widows and caregiving young people in HIV-affected households to safeguard land and other assets, within a wider supportive environment that seeks to tackle structural inequalities.

Flyktingguide: En väg till integration? : Brukarutvärdering av projektet Flyktingguide i Falun

In this qualitative user evaluation participants in the project refugee guide, Falun, was interviewed about their experience of the project and how the project contributed to their integration into society and establishment on the labor market. The collection of empirical data has been made by six interviews. The results of the evaluation indicate that participants feel that they through the project had the opportunity to meet new people, practice the language and learn about each other's culture. The results also show that participants are satisfied with the project. Some participants expressed a desire to meet with several people at once while others don´t have that need. Furthermore, the interviews shows that establishment on labor market occurred through job placement and not through participation in the project. Integration proved to be a difficult concept to define, but the interviews show that the participants have a perception that it is about learning the Swedish language and culture.

Empresários nanicos, garantias e acesso à crédito

Visamos contribuir para o desenvolvimento do crédito produtivo popular no Brasil. Um passo nesta direção é diminuir a assimetria de informações existentes entre os gestores de políticas públicas e o seu público-alvo. O presente trabalho se beneficia da melhor oportunidade disponível de explorar informações sobre os negócios nanicos, a pesquisa sobre Economia Informal Urbana – ECINF, realizada pelo IBGE em 1997, onde foram entrevistados quase 50000 conta-próprias e empregadores até cinco empregados. Descrevemos a partir da ECINF as formas de acesso ao crédito destes estabelecimentos. O mercado de microcrédito se revela incipiente nas áreas urbanas do país, apenas 7% dos negócios nanicos obtiveram acesso a crédito nos três meses anteriores a pesquisa. Descrevemos o padrão de correlações do uso do crédito produtivo popular com outras variáveis, em particular àquelas ligadas a posse de garantias reais ou colaterais sociais nas áreas urbanas brasileiras. A ligação a alguns elementos do capital social está correlacionada à obtenção do crédito, onde a vantagem aumenta em 33% para quem está associado a algum sindicato, associação ou cooperativa em relação aos que não possuem ligação com estes. A questão da legalidade também apresenta correlação forte para conseguir o acesso a crédito: quem possui constituição jurídica possui uma vantagem de 55% maior em relação aos que não possuem. Destaca-se a variável indicativa da posse de equipamentos, é nesta variável que observamos um dos maiores valores na estimativa, onde a vantagem de quem utiliza é aproximadamente duas vezes maior em relação a quem não utiliza. O fato de estar numa região metropolitana influi pouco na obtenção do crédito, a vantagem é apenas 10% maior do que as pessoas que encontram-se nas demais áreas urbanas. De maneira geral os resultados são consistentes com a importância atribuída na literatura por garantias reais e alternativas na obtenção de crédito.

Speculative attacks, openness and crises

In this paper we propose a dynamic stochastic general equilibrium model to evaluate financial adjustments that some emerging market economies went through to overcome external crises during the latest decades, such as default and local currency devaluation. We assume that real devaluation can be used to avoid external debt default, to improve trade balance and to reduce the real public debt level denominated in local currency. Such effects increase the government ability to deal with external crisis, but also have costs in terms of welfare, related to expected inflation, reductions in private investments and higher interest to be paid over the public debt. We conclude that openness improves expected welfare as it allows for a better devaluation-response technology against crises. We also present results for 32 middle-income countries, verifying that the proposed model can indicate, in a stylized way, the preferences for default-devaluation options and the magnitude of the currency depreciation required to overcome 48 external crises occurred as from 1971. Finally, as we construct our model based on the Cole-Kehoe self-fulfilling debt crisis model ([7]), adding local debt and trade, it is important to say that their policy alternatives to leave the crisis zone remains in our extended model, namely, to reduce the external debt level and to lengthen its maturity.

Informação, participação e cobrança pelo uso da água: um relato do processo no comitê para integração da bacia do rio Paraíba do Sul

Esta dissertação relata o uso da informação no processo decisório havido na bacia do rio Paraíba do Sul em torno da implementação da cobrança pelo uso da água bruta,instituída pela Política Nacional de Recursos Hídricos. De grande importância no cenárionacional essa bacia hidrográfica foi escolhida como foco de estudo por se tratar de umaexperiência pioneira de implementação de um Sistema de Gestão de Recursos Hídricosem rios de domínio da União, tendo como pano de fundo a complexidade do federalismobrasileiro e a falta de tradição em processos participativos para tomada de decisão nestecampo. O estudo mostra, ainda, como a cobrança pelo uso da água foi um fator deaglutinação dos atores da bacia, como o capital social acumulado foi fundamental para oprocesso de negociação, e finalmente, como o uso da informação técnica, ao contráriodo que se imaginava, proporcionou avanços significativos na metodologia e critériospropostos para implementação desse importante instrumento de gestão das águas.

O outro lado de cá: histórias e memórias de Cachoeira da Prata

O principal objetivo dessa dissertação é analisar, através de um estudo caso, como a questão do “preconceito intergrupal” pode ser percebida no desenvolvimento histórico de pequenos municípios brasileiros. Escolhendo a história da memória da cidade de Cachoeira da Prata como objeto central, buscamos discutir como ocorreu o processo de diferenciação social da pequena comunidade formada pelos descendentes do ex-escravo Nicolau Teixeira do restante da cidade. Para tanto, dividimos a dissertação em duas partes. A primeira é formada pelos três primeiros capítulos, nos quais apresentamos a vila fabril de Cachoeira de Macacos como o cenário, no qual o cel. Américo Teixeira é identificado como o líder maior de um projeto de domínio político e industrial que deixou marcas duradouras na memória da população mais antiga da cidade. Nesse contexto, buscamos discutir como o fenômeno do pós-emancipação da escravidão se manifestou na localidade, analisando parte da trajetória de vida do ex-escravo Nicolau Teixeira, um leal apoiador do projeto político do cel. Américo, que se tornou, na primeira metade do século XX, o patriarca de uma comunidade criada nas imediações da antiga vila fabril. Na segunda parte, composta exclusivamente pelo quarto capítulo, discutimos de maneira conjugada, a história da diferenciação social da comunidade e diferentes posicionamentos políticos e metodológicos que adotamos ao longo da pesquisa. Após essa análise, concluímos que só é possível entender os meandros do processo que levou os descendentes de Nicolau Teixeira à condição de exclusão social após percebê-los como atores capazes de elaborar narrativas e representações que auxiliam a população de Cachoeira da Prata a conhecer um “outro lado” da história local.

Crime and punishment with habit formation

Moral concepts affect crime supply. This idea is modelled assuming that illegal activities is habit forming. We introduce habits in a intertemporal general equilibrium framework to illegal activities and compare its outcomes with a model without habit formation. The findings are that habit and crime presents a non linear relationship that hinges upon the level of capital and habit formation. It is possible to show that while the effect of habit on crime is negative for low levels o habit formation it becomes positive as habits goes up. Secondly habit reduces the marginal effect of illegal activities return on crime. Finally, the effect of habit on crime depends positively on the amount of capital. This could explain the relationship between size of cities and illegal activity.

Análise de formações comunitárias em favelas - metodologia, perspectivas e resultados - o modelo da associação comunitária Monte Azul (ACOMA)

O objetivo desta pesquisa é retratar a qualidade de vida na Favela Monte Azul tendo em vista a atuação de duas organizações comunitárias - Associação Comunitária Monte Azul (ACOMA) e a Comissão de Moradores - considerando sua história, ideologia, perspectivas e resultados obtidos na transformação da comunidade. Constata-se atualmente que experiências com organizações promotoras do desenvolvimento comunitário não têm sistematizado e apresentado os resultados alcançados na melhoria da qualidade de vida. Isto é importante para a própria comunidade e organização que, juntas, podem buscar soluções para os problemas identificados. O diferencial positivo na qualidade de vida dos moradores desta favela reflete o trabalho de mais de vinte anos da ACOMA e da comunidade organizada.
