El capital social como factor de producción en los sistemas de agronegocios en Argentina : un análisis comparado de los sistemas aviar, vitivinícola y vacuno

El sector agroalimentario se ha convertido en el de mayor importancia durante los 90 para la economía argentina junto a los sectores del petróleo y acero. Sin embargo, el gran empuje proveniente del 'campo' no se traslada al resto de redes de abatecimiento de alimentos. El desarrollo veloz de las interrelaciones comerciales que conducen al establecimiento de distintas formas de relaciones para el abastecimiento de alimentos es un fenómeno clave en las economías agroalimentarias modernas. Los principales actores de las cadenas agroindustriales deben diseñar las mejores opciones respecto del diseño de sus relaciones comerciales. El objetivo principal del siguiente trabajo es identificar al capital social como un factor de producción para el desarrolo de los sistemas de agronegocios argentinos. Los objetivos específicos serán identificar el nivel de capital social del sistema de ganados y carnes vacuna, del sistema avícola y del sistema vitivinícola de la Argentina. El trabajo determina que el desarrollo global de los agronegocios en Argentina depende del grado de enforcement de la ley y los contratos y del nivel de acción colectiva. Dentro de las variables estudiadas 'confianza', 'acción colectiva' y 'cooperación y ética' presenta altos niveles en las tres variables, el sistema vitivinícola medios y el sistema de ganados y carnes vacuno los presenta bajos. El sistema de negocios avícola es la que marca un mayor desarrollo de capital social a lo largo de la muestra. El nivel de confianza expresado por sus miembros demuestra su capacidad para resolver los dilemas que presenta la acción colectiva en el negocio real, contrariamente al sistema vacuno, mientras que el sistema vitivinícola se coloca en una posición media. El sistema avícola presenta mayor cantidad de contratos formales y como vimos un mayor respeto por su cumplimiento más allá de la incompltitud de los mismos. La falta de contratos formales y la falta de control por parte del Estado, en mayor medida en el subsector vacuno por sobre el vitivinícola, favorece el doble estándar impositivo, comercial y sanitario (no en el caso del vino). En tal sentido, el no respeto por el conjunto de reglas de conducta formales (leyes, tradiciones, costumbres, sistema de valores, religiones, tendencias sociológicas, etc.), es decir las instituciones, que facilitan la coordinación o rigen las relaciones entre individuos o grupos, le agrega mayor incertidumbre a la interacción humana

Spaces of observation and obscurity: cinematic prisons of light and dark

In The Eye of Power, Foucault delineated the key concerns surrounding hospital architecture in the latter half of the eighteenth century as being the ‘visibility of bodies, individuals and things'. As such, the ‘new form of hospital' that came to be developed ‘was at once the effect and support of a new type of gaze'. This was a gaze that was not simply concerned with ways of minimising overcrowding or cross-contamination. Rather, this was a surveillance intended to produce knowledge about the pathological bodies contained within the hospital walls. This would then allow for their appropriate classification. Foucault went on to describe how these principles came to be applied to the architecture of prisons. This was exemplified for him in the distinct shape of Bentham's panopticon. This circular design, which has subsequently become an often misused synonym for a contemporary culture of surveillance, was premised on a binary of the seen and the not-seen. An individual observer could stand at the central point of the circle and observe the cells (and their occupants) on the perimeter whilst themselves remaining unseen. The panopticon in its purest form was never constructed, yet it conveys the significance of the production of knowledge through observation that became central to institutional design at this time and modern thought more broadly. What is curious though is that whilst the aim of those late eighteenth century buildings was to produce wellventilated spaces suffused with light, this provoked an interest in its opposite. The gothic movement in literature that was developing in parallel conversely took a ‘fantasy world of stone walls, darkness, hideouts and dungeons…' as its landscape (Vidler, 1992: 162). Curiously, despite these modern developments in prison design, the façade took on these characteristics. The gothic imagination came to describe that unseen world that lay behind the outer wall. This is what Evans refers to as an architectural ‘hoax'. The façade was taken to represent the world within the prison walls and it was the façade that came to inform the popular imagination about what occurred behind it. The rational, modern principles ordering the prison became conflated with the meanings projected by and onto the façade. This confusion of meanings have then been repeated and reenforced in the subsequent representations of the prison. This is of paramount importance since it is the cinematic and televisual representation of the prison, as I argue here and elsewhere, that maintain this erroneous set of meanings, this ‘hoax'.

The effect of ownership structure, country governance, and financial development on the capital structure of unlisted eastern European firms

This paper investigates the determinants of capital structure for a sample of 20,713 unlisted firms from 11 eastern European countries over the period 1994-2004. We employ usual firm-specific financial variables as well as country-specific variables that describe the degrees of governance structure and financial development of each country. Using regression analysis, our results indicate that firm ownership concentration and country governance structure are insignificant explanatory variables to the degree of leverage of the firms in our sample. On the other hand, indicators of country financial development are robust determinants of capital structure. However, the marginal explanatory power of country-specific variables is small. We conclude that firm-specific characteristics are decisive in capital structure.

Sediment transfer and accumulation in two contrasting salt marsh/mudflat systems: the Seine estuary (France) and the Medway estuary (UK)

Understanding the dynamics of fine sediment transport across the upper intertidal zone is critical in managing the erosion and accretion of intertidal areas, and in managed realignment/estuarine habitat recreation strategies. This paper examines the transfer of sediments between salt marsh and mudflat environments in two contrasting macrotidal estuaries: the Seine (France) and the Medway (UK), using data collected during two joint field seasons undertaken by the Anglo-French RIMEW project (Rives-Manche Estuary Watch). High-resolution ADCP, Altimeter, OBS and ASM measurements from mudflat and marsh surface environments have been combined with sediment trap data to examine short-term sediment transport processes under spring tide and storm flow conditions. In addition, the longer-term accumulation of sediment in each salt marsh system has been examined via radiometric dating of sediment cores. In the Seine, rapid sediment accumulation and expansion of salt marsh areas, and subsequent loss of open intertidal mudflats, is a major problem, and the data collected here indicate a distinct net landward flux of sediments into the marsh interior. Suspended sediment fluxes are much higher than in the Medway estuary (averaging 0.09 g/m(3)/s), and vertical accumulation rates at the salt marsh/mudflat boundary exceed 3 cm/y. Suspended sediment data collected during storm surge conditions indicate that significant in-wash of fine sediments into the marsh interior can occur during (and following) these high-magnitude events. In contrast to the Seine, the Medway is undergoing erosion and general loss of salt marsh areas. Suspended sediment fluxes are of the order of 0.03 g/m(3)/s, and the marsh system here has much lower rates of vertical accretion (sediment accumulation rates are ca. 4 mm/y). Current velocity data for the Medway site indicate higher velocities on the ebb tide than occur on the flood tide, which may be sufficient to remobilise sediments deposited on the previous tide and so force net removal of material from the marsh.

Safe spaces and sense of identity: views and experiences of lesbian, gay and bisexual young people

Empirical data on the life experiences of contemporary school-age lesbian, gay and bisexual (LGB) young people in Britain remains somewhat sparse. This paper reports the preliminary findings of a study conducted at a recently-initiated LGB youth Summer School. To further an appreciation of issues of concern to today's LGB teenagers, in-depth interviews were conducted with 10 Summer School participants (five female and five male, aged 15-18 years). The aim was to elicit their views and experiences relating to their need for support such as that offered by the Summer School. Themes drawn from participants' interviews are presented. Key issues included: being positioned as different by their majority heterosexual peers; feelings of isolation and loneliness in their peer groups and families; difficulties in finding others like themselves for companionship; and the importance of meeting more LGB people of their own age.
