Descentralización, autogestión, gestión local. Estudio de caso de un municipio en La Pampa, Argentina

Los municipios, en los últimos veinticinco años, han cambiado sus roles. En la actualidad, los gobernantes locales asumen formas de gestionar que atienden a las crecientes demandas sociales de sus vecinos, redefiniendo las políticas públicas municipales. Parte de la tarea de gestión es el ordenamiento territorial como estrategia para orientar la distribución espacial del desarrollo, de acuerdo con los recursos disponibles, con el mejor uso que a los mismos se da en términos sociales, económicos y ambientales. Concretarlo implica cambios cualitativos importantes, adecuaciones en la gestión político-administrativa. En Victorica, La Pampa, la autogestión se perfila como una de las características más sobresalientes. La dinámica gestión de su territorio es ejemplo para otros municipios que intentan imitar el estilo. Los actores sociales son la clave del cambio.

El progreso de microrregionalización como estrategia del desarrollo local : Un estudio de la provincia de Chaco

El artículo analiza la experiencia de desarrollo llevada a cabo por el gobierno del Chaco, Argentina, entre los años 2000 y 2007 mediante la organización del territorio provincial en microrregiones. El énfasis ha sido puesto en los aspectos participativos y en el sentido que el proceso adquirió para sus propios actores. La noción de territorio, en su vinculación con el término ?campo? de Bourdieu, constituyó un concepto relevante a los efectos del análisis. En primer lugar, se explicitan los ejes teóricos del discurso oficial que origina y promueve el proceso: la opción por el desarrollo sustentable, la perspectiva de integración de lo económico con lo social y la generación de espacios participativos para la gestión de las políticas públicas. En la descripción de la experiencia se identifican las tensiones, actores y lógicas subyacentes: iniciativas y razones para la creación de cada microrregión, modalidad de la participación, consecuencias y obstáculos. El análisis muestra que la tensión entre los intereses económicos de los sectores productivos más estabilizados y las expectativas sociales de los sectores vulnerados no logra dirimirse, por lo cual la voluntad asociativa discurre en el marco de esta lógica. El Estado no puede ser un actor prescindente. Estos procesos deben contribuir a afirmar la identidad cultural y el sentido de pertenencia desde una perspectiva que reconozca la diversidad pero no legitime la desigualdad. En este contexto, se destaca la importancia de abrir espacios que permitan nuclear a la población de las distintas jurisdicciones para la discusión de ejes, la definición de políticas y la construcción de consensos que incluyan el reconocimiento del otro como igual, fortaleciendo los mecanismos de cohesión social

Lo local y lo global en la producción científica argentina con visibilidad en Scopus, 2008-2012 : Dimensiones nacionales e internacionales de la investigación

En Argentina, desde comienzos del presente siglo, las políticas científicas y tecnológicas explícitas evidencian un claro interés en la producción de conocimientos orientados a la resolución de problemas sociales, productivos y medioambientales de carácter local. Desde la bibliometría se vienen realizando estudios sobre la producción científica de los países, existiendo varios antecedentes que enfocan la atención en la producción científica argentina. Sin embargo, son incipientes y escasos los trabajos sobre la producción científica enfocada a temas locales. Los objetivos de esta investigación son analizar y describir la relación entre lo local y lo global en la producción científica argentina con visibilidad en Scopus en el período 2008-2012, y comparar indicadores de publicación, colaboración y liderazgo desde las dimensiones nacionales e internacionales de las prácticas de comunicación científica. Los resultados muestran ;que una cuarta parte de la producción está orientada a temas locales, con destacada presencia de contribuciones en Ciencias sociales, Economía y Administración, Ciencias agrícolas y biológicas, Ciencias de la tierra y relacionadas con el ambiente. Un alto porcentaje de esta producción se publica en revistas extra-regionales. Hay un mayor predominio de investigación en colaboración nacional y sin colaboración en los temas locales. Sin embargo casi un tercio de la producción se realizó en colaboración internacional, con diferencias porcentuales según las disciplinas. Por último, destaca el alto porcentaje de producción liderada por investigadores de instituciones argentinas en todas las disciplinas, tanto en los temas locales como globales

Mathematical models for the arrangement and the cleaning of the river basin and surroundings of the river sandy grounds to its passage by the city of Salta (Argentina)

The province of Salta is located the Northwest of Argentina in the border with Bolivia, Chile and Paraguay. Its Capital is the city of Salta that concentrates half of the inhabitants of the province and has grown to 600000 hab., from a small active Spanish town well founded in 1583. The city is crossed by the Arenales River descending from close mountains at North, source of water and end of sewers. But with actual growing it has become a focus of infection and of remarkable unhealthiness. It is necessary to undertake a plan for the recovery of the river, directed to the attainment of the well-being and to improve the life?s quality of the Community. The fundamental idea of the plan is to obtain an ordering of the river basin and an integral management of the channel and its surroundings, including the cleaning out. The improvement of the water?s quality, the healthiness of the surroundings and the improvement of the environment, must go hand by hand with the development of sport activities, of relaxation, tourism, establishment of breeding grounds, kitchen gardens, micro enterprises with clean production and other actions that contribute to their benefit by the society, that being a basic factor for their care and sustainable use. The present pollution is organic, chemical, industrial, domestic, due to the disposition of sweepings and sewer effluents that affects not only the flora and small fauna, destroying the biodiversity, but also to the health of people living in their margins. Within the plan it will be necessary to consider, besides hydric and environmental cleaning and the prevention of floods, the planning of the extraction of aggregates, the infrastructure and consolidation of margins works and the arrangement of all the river basin. It will be necessary to consider the public intervention at state, provincial and local level, and the private intervention. In the model it has been necessary to include the sub-model corresponding to the election of the entity to be the optimal instrument to reach the proposed objectives, giving an answer to the social, environmental and economic requirements. For that the authors have used multi-criteria decision methods to qualify and select alternatives, and for the programming of their implementation. In the model the authors have contemplated the short, average and long term actions. They conform a Paretooptimal alternative which secures the ordering, integral and suitable management of the basin of the Arenales River, focusing on its passage by the city of Salta.

La localización de la clase creativa en ciudades turísticas. Un análisis a escala local del sistema urbano Mediterráneo español

La tendencia a la concentración de flujos económicos y humanos en las principales aglomeraciones ha generado unos polos de atracción global en detrimento de las opciones de desarrollo del resto de territorios. Sin embargo la recomposición territorial está siendo más compleja y afecta también al territorio no metropolitano. La introducción de elementos de creatividad en las economías urbanas es un ejemplo de la relativa dispersión territorial de nuevas actividades productivas. La localización de actividades económicas creativas ha sido analizada para el caso de ciudades medias, periferias urbanas y espacios rurales, pero no para el de ciudades turísticas. El objetivo del trabajo es analizar, a escala local y partiendo del cálculo de un índice sintético de creatividad, el comportamiento de dicho índice y en qué medida la clase creativa se localiza en los destinos turísticos del mediterráneo español y las Islas Canarias en comparación con otros tipos de municipios y entre municipios turísticos según su grado de especialización. Los resultados obtenidos permiten formular la hipótesis sobre cómo contribuyen los espacios turísticos a la reorganización productiva del territorio y valorar sus posibilidades de competitividad basadas en la mejora de la tolerancia, la innovación y el emprendimiento, proporcionando oportunidades de desarrollo más integrales y diversificadas en el momento de crisis actual.

The missing ingredient:inter-municipal cooperation and central-local relations in the UK

The thrust of the argument presented in this chapter is that inter-municipal cooperation (IMC) in the United Kingdom reflects local government's constitutional position and its exposure to the exigencies of Westminster (elected central government) and Whitehall (centre of the professional civil service that services central government). For the most part councils are without general powers of competence and are restricted in what they can do by Parliament. This suggests that the capacity for locally driven IMC is restricted and operates principally within a framework constructed by central government's policy objectives and legislation and the political expediencies of the governing political party. In practice, however, recent examples of IMC demonstrate that the practices are more complex than this initial analysis suggests. Central government may exert top-down pressures and impose hierarchical directives, but there are important countervailing forces. Constitutional changes in Scotland and Wales have shifted the locus of central- local relations away from Westminster and Whitehall. In England, the seeding of English government regional offices in 1994 has evolved into an important structural arrangement that encourages councils to work together. Within the local government community there is now widespread acknowledgement that to achieve the ambitious targets set by central government, councils are, by necessity, bound to cooperate and work with other agencies. In recent years, the fragmentation of public service delivery has affected the scope of IMC. Elected local government in the UK is now only one piece of a complex jigsaw of agencies that provides services to the public; whether it is with non-elected bodies, such as health authorities, public protection authorities (police and fire), voluntary nonprofit organisations or for-profit bodies, councils are expected to cooperate widely with agencies in their localities. Indeed, for projects such as regeneration and community renewal, councils may act as the coordinating agency but the success of such projects is measured by collaboration and partnership working (Davies 2002). To place these developments in context, IMC is an example of how, in spite of the fragmentation of traditional forms of government, councils work with other public service agencies and other councils through the medium of interagency partnerships, collaboration between organisations and a mixed economy of service providers. Such an analysis suggests that, following changes to the system of local government, contemporary forms of IMC are less dependent on vertical arrangements (top-down direction from central government) as they are replaced by horizontal modes (expansion of networks and partnership arrangements). Evidence suggests, however that central government continues to steer local authorities through the agency of inspectorates and regulatory bodies, and through policy initiatives, such as local strategic partnerships and local area agreements (Kelly 2006), thus questioning whether, in the case of UK local government, the shift from hierarchy to network and market solutions is less differentiated and transformation less complete than some literature suggests. Vertical or horizontal pressures may promote IMC, yet similar drivers may deter collaboration between local authorities. An example of negative vertical pressure was central government's change of the systems of local taxation during the 1980s. The new taxation regime replaced a tax on property with a tax on individual residency. Although the community charge lasted only a few years, it was a highpoint of the then Conservative government policy that encouraged councils to compete with each other on the basis of the level of local taxation. In practice, however, the complexity of local government funding in the UK rendered worthless any meaningful ambition of councils competing with each other, especially as central government granting to local authorities is predicated (however imperfectly) on at least notional equalisation between those areas with lower tax yields and the more prosperous locations. Horizontal pressures comprise factors such as planning decisions. Over the last quarter century, councils have competed on the granting of permission to out-of-town retail and leisure complexes, now recognised as detrimental to neighbouring authorities because economic forces prevail and local, independent shops are unable to compete with multiple companies. These examples illustrate tensions at the core of the UK polity of whether IMC is feasible when competition between local authorities heightened by local differences reduces opportunities for collaboration. An alternative perspective on IMC is to explore whether specific purposes or functions promote or restrict it. Whether in the principle areas of local government responsibilities relating to social welfare, development and maintenance of the local infrastructure or environmental matters, there are examples of IMC. But opportunities have diminished considerably as councils lost responsibility for services provision as a result of privatisation and transfer of powers to new government agencies or to central government. Over the last twenty years councils have lost their role in the provision of further-or higher-education, public transport and water/sewage. Councils have commissioning power but only a limited presence in providing housing needs, social care and waste management. In other words, as a result of central government policy, there are, in practice, currently far fewer opportunities for councils to cooperate. Since 1997, the New Labour government has promoted IMC through vertical drivers and the development; the operation of these policy initiatives is discussed following the framework of the editors. Current examples of IMC are notable for being driven by higher tiers of government, working with subordinate authorities in principal-agent relations. Collaboration between local authorities and intra-interand cross-sectoral partnerships are initiated by central government. In other words, IMC is shaped by hierarchical drivers from higher levels of government but, in practice, is locally varied and determined less by formula than by necessity and function. © 2007 Springer.

Local shell-side coefficients in shell and tube exchanges the use of a mass transfer technique

A diffusion-controlled electrochemical mass transfer technique has been employed in making local measurements of shell-side coefficients in segmentally baffled shell and tube heat exchangers. Corresponding heat transfer data are predicted through the Chilton and Colburn heat and mass transfer analogy. Mass transfer coefficients were measured for baffle spacing lengths of individual tubes in an internal baffle compartment. Shell-side pressure measurements were also made. Baffle compartment average coefficients derived from individual tube coefficients are shown to be in good agreement with reported experimental bundle average heat transfer data for a heat exchanger model of similar geometry. Mass transfer coefficients of individual tubes compare favourably with those obtained previously by another mass transfer technique. Experimental data are reported for a variety of segmental baffle configurations over the shell-side Reynolds number range 100 to 42 000. Baffles with zero clearances were studied at three baffle cuts and two baffle spacings. Baffle geometry is shown to have a large effect on the distribution of tube coefficients within the baffle compartment. Fluid "jetting" is identified with some baffle configurations. No simple characteristic velocity is found to correlate zonal or baffle compartment average mass transfer data for the effect of both baffle cut and baffle spacing. Experiments with baffle clearances typical of commercial heat exchangers are also reported. The effect of leakage streams associated with these baffles is identified. Investigations were extended to double segmental baffles for which no data had previously been published. The similarity in the shell-side characteristics of this baffle arrangement and two parallel single segmental baffle arrangements is demonstrated. A general relationship between the shell-side mass transfer performance and pressure drop was indicated by the data for all the baffle configurations examined.

Application of Numerical Methods to Study Arrangement and Fracture of Lithium-Ion Microstructure

The focus of this work is to develop and employ numerical methods that provide characterization of granular microstructures, dynamic fragmentation of brittle materials, and dynamic fracture of three-dimensional bodies.

We first propose the fabric tensor formalism to describe the structure and evolution of lithium-ion electrode microstructure during the calendaring process. Fabric tensors are directional measures of particulate assemblies based on inter-particle connectivity, relating to the structural and transport properties of the electrode. Applying this technique to X-ray computed tomography of cathode microstructure, we show that fabric tensors capture the evolution of the inter-particle contact distribution and are therefore good measures for the internal state of and electronic transport within the electrode.

We then shift focus to the development and analysis of fracture models within finite element simulations. A difficult problem to characterize in the realm of fracture modeling is that of fragmentation, wherein brittle materials subjected to a uniform tensile loading break apart into a large number of smaller pieces. We explore the effect of numerical precision in the results of dynamic fragmentation simulations using the cohesive element approach on a one-dimensional domain. By introducing random and non-random field variations, we discern that round-off error plays a significant role in establishing a mesh-convergent solution for uniform fragmentation problems. Further, by using differing magnitudes of randomized material properties and mesh discretizations, we find that employing randomness can improve convergence behavior and provide a computational savings.

The Thick Level-Set model is implemented to describe brittle media undergoing dynamic fragmentation as an alternative to the cohesive element approach. This non-local damage model features a level-set function that defines the extent and severity of degradation and uses a length scale to limit the damage gradient. In terms of energy dissipated by fracture and mean fragment size, we find that the proposed model reproduces the rate-dependent observations of analytical approaches, cohesive element simulations, and experimental studies.

Lastly, the Thick Level-Set model is implemented in three dimensions to describe the dynamic failure of brittle media, such as the active material particles in the battery cathode during manufacturing. The proposed model matches expected behavior from physical experiments, analytical approaches, and numerical models, and mesh convergence is established. We find that the use of an asymmetrical damage model to represent tensile damage is important to producing the expected results for brittle fracture problems.

The impact of this work is that designers of lithium-ion battery components can employ the numerical methods presented herein to analyze the evolving electrode microstructure during manufacturing, operational, and extraordinary loadings. This allows for enhanced designs and manufacturing methods that advance the state of battery technology. Further, these numerical tools have applicability in a broad range of fields, from geotechnical analysis to ice-sheet modeling to armor design to hydraulic fracturing.
