Forces of agglomeration and dispersal in rural business networks: a social network analysis

Two concepts in rural economic development policy have been the focus of much research and policy action: the identification and support of clusters or networks of firms and the availability and adoption by rural businesses of Information and Communication Technologies (ICT). From a theoretical viewpoint these policies are based on two contrasting models, with clustering seen as a process of economic agglomeration, and ICT-mediated communication as a means of facilitating economic dispersion. The study’s conceptual framework is based on four interrelated elements: location, interaction, knowledge, and advantage, together with the concept of networks which is employed as an operationally and theoretically unifying concept. The research questions are developed in four successive categories: Policy, Theory, Networks, and Method. The questions are approached using a study of two contrasting groups of rural small businesses in West Cork, Ireland: (a) Speciality Foods, and (b) firms in Digital Products and Services. The study combines Social Network Analysis (SNA) with Qualitative Thematic Analysis, using data collected from semi-structured interviews with 58 owners or managers of these businesses. Data comprise relational network data on the firms’ connections to suppliers, customers, allies and competitors, together with linked qualitative data on how the firms established connections, and how tacit and codified knowledge was sourced and utilised. The research finds that the key characteristics identified in the cluster literature are evident in the sample of Speciality Food businesses, in relation to flows of tacit knowledge, social embedding, and the development of forms of social capital. In particular the research identified the presence of two distinct forms of collective social capital in this network, termed “community” and “reputation”. By contrast the sample of Digital Products and Services businesses does not have the form of a cluster, but matches more closely to dispersive models, or “chain” structures. Much of the economic and social structure of this set of firms is best explained in terms of “project organisation”, and by the operation of an individual rather than collective form of “reputation”. The rural setting in which these firms are located has resulted in their being service-centric, and consequently they rely on ICT-mediated communication in order to exchange tacit knowledge “at a distance”. It is this factor, rather than inputs of codified knowledge, that most strongly influences their operation and their need for availability and adoption of high quality communication technologies. Thus the findings have applicability in relation to theory in Economic Geography and to policy and practice in Rural Development. In addition the research contributes to methodological questions in SNA, and to methodological questions about the combination or mixing of quantitative and qualitative methods.

Sea ice and wind variability during the Holocene in East Antarctica

A high-resolution continuous record of diatom census counts and diatom specific biomarkers in sediment core NBP0101-JPC24 allows assessment of oceanographic and environmental conditions in eastern Prydz Bay during the deglaciation (11 100-9000 cal yr BP) at decadal timescale. Our study improves previous snapshots investigations based on resin-embedded thin sections and presents a new proxy that compliments the diatom census counts. Our results suggest that the ice sheet retreat over the core site is dated at ~11 100 cal yr BP, setting the onset of local deglaciation and subsequent open marine conditions. The glacial retreat in Prydz Bay is due to global warming initiated at 18 cal ka BP and the regional development of the Prydz Bay cyclonic gyre. Our results further demonstrate that the deglaciation in eastern Prydz Bay can be separated in four phases: the first between 11 100 and 10 900 cal yr BP when the ice shelf was proximal and sea ice was almost perennial; the second and the third phases between 10 900-10 400 cal yr BP and 10 400-9900 cal yr BP, respectively, when the ice shelf retreated and seasonal sea ice cycle consequently developed promoting warmer water to pump into the bay within the gyre, which in turn forced the ice shelf recession and the yearly sea ice cycle establishment; and the fourth between 9900 and 9000 cal yr BP when Holocene condition were set with a recurrent seasonal sea ice cycle and a well established Prydz Bay gyre.

Cultural Politics of Resilience in Kingston, Jamaica

Recently, resilience has become a catchall solution for some of the world’s most pressing ecological, economic and social problems. This dissertation analyzes the cultural politics of resilience in Kingston, Jamaica by examining them through their purported universal principles of adaptation and flexibility. On the one hand, mainstream development regimes conceptualize resilience as a necessary and positive attribute of economies, societies and cultures if we are to survive any number of disasters or disturbances. Therefore, in Jamaican cultural and development policy resilience is championed as both a means and an end of development. On the other hand, critics of resilience see the new rollout of resilience projects as deepening neoliberalism, capitalism and new forms of governmentality because resilience projects provide the terrain for new forms of securitization and surveillance practices. These scholars argue that resilience often forecloses the possibilities to resist that which threatens us. However, rather than dismissing resilience as solely a sign of domination and governmentality, this dissertation argues that resilience must be understood as much more ambiguous and complex, rather than within binaries such as subversion vs. neoliberal and resistance vs. resilience. Overly simplistic dualities of this nature have been the dominant approach in the scholarship thus far. This dissertation provides a close analysis of resilience in both multilateral and Jamaican government policy documents, while exploring the historical and contemporary production of resilience in the lives of marginalized populations. Through three sites within Kingston, Jamaica—namely dancehall and street dances, WMW-Jamaica and the activist platform SO((U))L HQ—this dissertation demonstrates that “resilience” is best understood as an ambiguous site of power negotiations, social reproduction and survival in Jamaica today. It is often precisely this ambiguous power of ordinary resilience that is capitalized on and exploited to the detriment of vulnerable groups. At once demonstrating creative negotiation and reproduction of colonial capitalist social relations within the realms of NGO, activist work and cultural production, this dissertation demonstrates the complexity of resilience. Ultimately, this dissertation draws attention to the importance of studying spaces of cultural production in order to understand the power and limits of contemporary policy discourses and political economy. 

Modelos de modernización para el desarrollismo: el influjo de las propuestas estadounidenses en el Servicio de Extensión Agraria (1955-1975)

Con este trabajo nos proponemos estudiar las políticas agrarias del franquismo y particularmente la creación y actuación del Servicio de Extensión Agraria (1955) en el contexto de la difusión de la Teoría de la Modernización. Comenzaremos con una contextualización de las relaciones culturales entre España y los EE.UU. y su potencial proyección sobre el ámbito rural. A continuación, prestaremos atención a la impronta del modelo extensionista norteamericano en la organización y metodología del Servicio de Extensión Agraria. Sin perder de vista la importancia de la escala estatal para la implementación y adaptación de las distintas políticas agrarias, atenderemos al contexto político e ideológico internacional como elemento que permite ampliar la comprensión y estudio de dichas políticas. En ese sentido, propondremos finalmente una primera aproximación comparativa al estudio del SEA en relación con diferentes experiencias de extensionismo agrario en Latinoamérica.

Predators on private land: broad-scale socioeconomic interactions influence large predator management

The proliferation of private land conservation areas (PLCAs) is placing increasing pressure on conservation authorities to effectively regulate their ecological management. Many PLCAs depend on tourism for income, and charismatic large mammal species are considered important for attracting international visitors. Broad-scale socioeconomic factors therefore have the potential to drive fine-scale ecological management, creating a systemic scale mismatch that can reduce long-term sustainability in cases where economic and conservation objectives are not perfectly aligned. We assessed the socioeconomic drivers and outcomes of large predator management on 71 PLCAs in South Africa. Owners of PLCAs that are stocking free-roaming large predators identified revenue generation as influencing most or all of their management decisions, and rated profit generation as a more important objective than did the owners of PLCAs that did not stock large predators. Ecotourism revenue increased with increasing lion (Panthera leo) density, which created a potential economic incentive for stocking lion at high densities. Despite this potential mismatch between economic and ecological objectives, lion densities were sustainable relative to available prey. Regional-scale policy guidelines for free-roaming lion management were ecologically sound. By contrast, policy guidelines underestimated the area required to sustain cheetah (Acinonyx jubatus), which occurred at unsustainable densities relative to available prey. Evidence of predator overstocking included predator diet supplementation and frequent reintroduction of game. We conclude that effective facilitation of conservation on private land requires consideration of the strong and not necessarily beneficial multiscale socioeconomic factors that influence private land management.

Developmental TVET rhetoric in-action: the White Paper for post-school education and training in South Africa

This paper explores the extent to which latest developments in the Technical and Vocational Education and Training System in South Africa respond to key principles espoused for a developmental, democratic and inclusionary ideal. The White Paper for post school education and training approved by Cabinet in November, 2013 is referred to by the Minister as the “definitive statement of the governments vision for the post school system” and as such represents a crucial strategy document intended to chart the TVET direction to 2030. Using key theoretical constructs from development theory, this paper provides an assessment of the TVET strategy contained is the paper and explores the extent to which it does respond to the agenda defined by the promise. It is argued that the challenges outlined are not yet able to provide the blueprint for a TVET transformative vision. It is concluded that while the development rhetoric contained in the paper is plausible, the creative tinkering of the system is unlikely to lead to the radical revisioning necessary for a truly transformative TVET system. The underlying assumptions regarding purpose, impact and outcome will need to be carefully reconsidered if the system is to be responsive to the promises of the democratic developmental ideal to which the government is committed.

Análisis y evaluación financiera del sistema policultivo de bocachico y tilapia roja en los departamentos del Atlántico y Magdalena

En este texto investigativo se realiza una avaluación financiera del proyecto Sistema Policultivo Bocachico – Tilapia Roja. Para llevar a cabo la investigación radica que en el momento en que se realizó el primer prototipo del Policultivo, no se tuvieron en cuenta aspectos de carácter financiero; además durante el proceso de estudio hemos aprendido elementos que ayudarían a mejorar el análisis financiero y económico del proyecto Policultivo. Con el estudio, los piscicultores e inversionistas dispondrán de unas herramientas calificadas y cualificadas que les permitan no sólo saber y estudiar el costo del montaje técnico de un policultivo, nociones de la piscicultura y cultivo de especies, sino, especialmente, conocer a través del uso de la metodología investigativa de la evaluación de proyectos, las fuentes más convenientes para el financiamiento, el potencial del negocio, un sostenido estudio de mercado y la generación de valor que representa el esfuerzo económico. Y por último distinguir el aporte eficaz que genera el proyecto en materia de desarrollo local o regional al contribuir con la generación de empleo, bienestar y al satisfacer ciertas necesidades sociales. Se pudo determinar que la producción y comercialización de Bocachico y Tilapia Roja mediante el Sistema Policultivos es factible, ya que mejora considerablemente los rendimientos de producción por unidad de área, y se aprovechan de la mejor manera los recursos disponibles. En el análisis se detectó que existe un gran potencial de demanda y de mercado, eficiente uso de los recursos financieros, técnicos, administrativos, legal, humanos, físicos y de infraestructura acorde con las necesidades del proyecto; y con una evaluación financiera que demuestra que el proyecto Sistema Policultivos es viable, rentable y se justifica realizar la inversión para desarrollarlo.

CottonInfo Extending Research

There are many ways in which research messages and findings can be extended to the expansive cotton community. As everyone learns differently it is crucial that information is delivered in a variety of ways to meet the various learning needs of the CottonInfo team’s broad audience. In addition different cotton production areas often require targeted information to address specific challenges. Successful implementation of innovative research outcomes typically relies on a history of cultivated communication between the researcher and the end-user, the grower. The CottonInfo team, supported by a joint venture between Cotton Seed Distributors, Cotton Research Development Corporation, Cotton Australia and other collaborative partners, represents a unique model of extension in Australian agriculture. Industry research is extended via regionally based Regional Development Officers backed by support from Technical Specialists. The 2015 Cotton Irrigation Technology Tour is one example of a successful CottonInfo capacity building activity. This tour took seven CRDC funded irrigation-specific researchers to Emerald, Moree and Nevertire to showcase their research and technologies. These events provided irrigators and consultants with the opportunity to hear first-hand from researchers about their technologies and how they could be applied onfarm. This tour was an example of how the CottonInfo team can connect growers and researchers, not only to provide an avenue for growers to learn about the latest irrigation research, but for researchers to receive feedback about their current and future irrigation research.

Análise do crescimento econômico no Rio Grande do Sul através da aplicação de cadeias de Markov

O estudo do crescimento econômico é de suma importância para que possamos averiguar a trajetória de uma economia ao longo do tempo, a proposta desse trabalho é analisar o crescimento econômico no estado do Rio Grande do Sul, através do instrumental das cadeias de Markov, a ideia principal do estudo está na hipótese de convergência de renda. Primeiramente será testado a hipótese de convergência de renda do estado por meio das microrregiões, para isso serão utilizados dados de produto per capita dos anos de 1990, 2000 e 2010. Também será testado a hipótese de convergência para os municípios do Conselho Regional de Desenvolvimento Sul, situado no Rio Grande do Sul, utilizando dados de renda per capita dos anos de 1991, 2000 e 2010. Os resultados obtidos para as microrregiões do Rio Grande do Sul mostram que as economias não estão convergindo em sua totalidade para uma classe de renda especifica, porém é percebido que no longo prazo haverá uma maior concentração das microrregiões nos extratos de renda próximos a média, o tempo esperado para que as economias cheguem ao seu estado estacionário é de seis períodos. Por meio dos resultados obtidos para a região do Corede Sul, temos que as economias convergirão em sua maioria para a classe de renda médio pobre, seguido pela classe dos médios ricos. Ambas as classes estão situadas próximas a média regional, sendo que as classes de renda pobre e rico situadas aos extremos serão extintas no longo prazo. O tempo esperado para que as economias cheguem ao estado estacionário é de onze períodos.

Rotatividade do mercado de trabalho no corede sul: uma análise ex-ante e ex-post a implementação do polo naval no munícipio de Rio Grande

A presente monografia tem como objetivo analisar a dinâmica do mercado de trabalho do Corede Sul, e avaliar a rotatividade dos trabalhadores a partir do impacto que o polo naval de Rio Grande trouxe para a região sul do estado do Rio Grande do Sul. As metodologias utilizadas foram dados em painel e modelos de diferenças em diferenças, nos períodos de 2003 a 2010 e 2003 a 2013 respectivamente, com o intuito de estimar os determinantes da rotatividade e analisar os impactos posteriores à implementação do polo na região. Foram estimados dois modelos, primeiramente um painel, mas o mesmo demonstrou problemas de endogenia entre as variáveis, e posteriormente um modelo de diferenças em diferenças, que foi estimado para melhor captar os efeitos para as cidades consideradas como tratadas no modelo, obtendo alguns coeficientes significativos. Foram gerados resultados estatisticamente representativos para as cidades de Rio Grande, Pelotas e São José do Norte, tendo a cidade de Rio Grande o maior resultado encontrado um aumento de 132% na rotatividade após 2006. Além disso, foi descoberto um processo de antecipação no mercado de trabalho no município de Rio Grande, em que a população já almejava uma melhor oportunidade de emprego, à medida que a construção do polo se consolidava.
