Estudios y perspectivas en turismo , 2012,
Abstract: La rápida transformación socio-económica de las últimas décadas hacia una sociedad basada en el conocimiento ha hecho que los intangibles estén cada vez más relacionados con el proceso de creación de valor dentro de las organizaciones. En este entorno las empresas con actividad turística cuyos servicios incluyen relevantes componentes inmateriales, necesitan profesionalizar la gestión para lograr su sustentabilidad acorde a las dinámicas exigencias emergentes de sus mercados. En este trabajo se muestra un caso de aplicación siguiendo las Directrices MERITUM para la medición y gestión de activos intangibles adaptadas a una empresa con actividad turística de la ciudad de Tandil y se expone un Informe de Capital intelectual. Los resultados de esta aplicación aparecen como promisorios dado que los empresarios reconocen que la identificación, medición y gestión de los intangibles les permite mejorar el desarrollo de sus empresas. In the last decades the rapid socio-economic transformation towards a knowledge-based society has meant that the intangibles are increasingly related to the value creation process within organizations. Enterprises with tourist activity include relevant intangible components in its services. They need to professionalize management towards sustainability according to dynamic demands of markets. The MERITUM Project has developed guidelines for measurement and management of intangible assets. This paper shows an application case following these guidelines adapted to a tourist SME (Small and Medium Enterprise) of the city of Tandil, Argentina, and an Intellectual Capital Report is presented. The results of this application become satisfactory as the owners of the tourist SME recognize that identification, measurement and management of intangibles allows improving their business development.
Restructuring polymers via nanoconfinement and subsequent release

Beilstein Journal of Organic Chemistry , 2012, DOI: 10.3762/bjoc.8.151
Abstract: During the past several years my students and I have been utilizing certain small-molecule hosts to create nanostructured polymers. This is accomplished by first forming noncovalently bonded inclusion complexes (ICs) between these small-molecule hosts and guest polymers, followed by the careful removal of the host crystalline lattice to obtain a coalesced bulk polymer. We have repeatedly observed that such coalesced polymer samples behave distinctly from those produced from their solutions or melts. Coalesced amorphous homopolymers exhibit higher glass-transition temperatures, while crystallizable homopolymers coalesced from their ICs display higher melting and crystallization temperatures, and sometimes different crystalline polymorphs. When ICs are formed with block copolymers or with two or more different homopolymers, the resulting coalesced samples can exhibit intimate mixing between the copolymer blocks, or between entire homopolymer chains. Each of the distinct behaviors observed for polymers coalesced from their ICs is a consequence of the structural organization of the polymer–host-ICs. Polymer chains in host-IC crystals are confined to occupy narrow channels (diameter ~0.5–1.0 nm) formed by the small-molecule hosts around the included guest polymers during IC crystallization. This results in the separation and high extension of the included guest polymer chains, which leads, following the careful removal of the host molecule lattice, to unique behaviors for the bulk coalesced polymer samples. Apparently, substantial degrees of the extended and unentangled natures of the IC-included chains are retained upon coalescence. In this review we summarize the behaviors and uses of coalesced polymers, and attempt to draw conclusions on the relationship between their behavior and the organization/structures/conformations of the constituent polymer chains achieved upon coalescence from their ICs.
A modelling study of the hydrographic structure of the Ross Sea

Ocean Science Discussions (OSD) , 2012, DOI: 10.5194/osd-9-3431-2012
Abstract: Dense water formation around Antarctica is recognized as one of the most important processes to climate modulation, since that is where the linkage between the upper and lower limbs of Global Thermohaline Circulation takes place. Assessing whether these processes may be affected by rapid climate changes and all the related feedbacks may be crucial to fully understand the ocean heat transport and to provide future projections. Applying the Coordinated Ocean-Ice Reference (CORE) normal year forcing we have run a 100-yr simulation using Regional Ocean Model System (ROMS) with explicit sea-ice/ice-shelf thermodynamics. The normal year consists of single annual cycle of all the data that are representative of climatological conditions over decades and can be applied repeatedly for as many years of model integration as necessary. The experiment employed a circumpolar variable resolution (1/2° to 1/24°) grid reaching less than 5 km over the inner continental shelf. With Optimum Parameter Analysis (OMP) the main Ross Sea (RS) water masses are identified: Antarctic surface water (AASW), circumpolar deep water (CDW), shelf water (SW) and ice shelf water (ISW). Current configuration allows very realistic representation, where results compare extremely well to the observations.
A numerical study of the Southern Ocean including a thermodynamic active ice shelf – Part 1: Weddell Sea

Geoscientific Model Development Discussions , 2012, DOI: 10.5194/gmdd-5-4037-2012
Abstract: There is a great amount of uncertainty regarding the understanding of the atmosphere-ocean-cryosphere interactions in the Southern Ocean despite the role that the region plays in our changing climate. With the aim of studying the relative importance of sea-ice and ice shelf processes in the Southern Ocean, a coupled ocean circulation sea-ice/ice shelf cavity model based on the Regional Ocean Model System (ROMS) is used in a periodic circumpolar domain with enhanced resolution in the Weddell Sea. A hierarchy of numerical experiments is performed where first a sea-ice model is used and then an ice shelf thermodynamic parameterization is included in order to evaluate the improvements resulting from each component. Results show that it is necessary to consider the formation and melting of sea-ice in order to adequately reproduce the observed hydrography and circulation. Inclusion of ice shelves cavities in the model only improves results if the ice shelf-ocean thermodynamic fluxes are active. Ice shelves and ocean interactions are an important process to be considered in order to obtain realistic hydrographic values under the ice shelf. The model framework presented in this work is a promising tool for analyzing the Southern Ocean response to future climate change scenarios.
Effects of grazing intensity and the use of veterinary medical products on dung beetle biodiversity in the sub-mountainous landscape of Central Italy

Abstract: Grazing extensification and intensification are among the main problems affecting European grasslands. We analyze the impact of grazing intensity (low and moderate) and the use of veterinary medical products (VMPs) on the dung beetle community in the province of Pesaro-Urbino (Italy). Grazing intensity is a key factor in explaining the diversity of dung beetles. In the case of the alpha diversity component, sites with a low level of grazing activity—related in a previous step to the subsequent abandonment of traditional farming—is characterized by a loss of species richness (q = 0) and a reduction in alpha diversity at the levels q = 1 and q = 2. In the case of beta diversity, sites with a different grazing intensity show remarkable differences in terms of the composition of their species assemblages. The use of VMPs is another important factor in explaining changes in dung beetle diversity. In sites with a traditional use of VMPs, a significant loss of species richness and biomass is observed, as is a notable effect on beta diversity. In addition, the absence of indicator species in sites with a historical use of VMPs corroborates the hypothesis that these substances have a ubiquitous effect on dung beetles. However, the interaction between grazing activity and VMPs when it comes to explaining changes in dung beetle diversity is less significant (or is not significant) than the main effects (each factor separately) for alpha diversity, biomass and species composition. This may be explained if we consider that both factors affect the various species differently. In other words, the reduction in dung availability affects several larger species more than it does very small species, although this does not imply that the former are more susceptible to injury caused by the ingestion of dung contaminated with VMPs. Finally, in order to prevent negative consequences for dung beetle diversity, we propose the maintenance of a moderate grazing intensity and the rational use of VMPs. It is our view that organic management can prevent excessive extensification while providing an economic stimulus to the sector. Simultaneously, it can also prevent the abuse of VMPs

Abstract: Objetivo: se construyó un índice mensual de precios al productor de ganado vacuno de levante y gordo en el Departamento de Sucre, Colombia, y se examinaron las relaciones existentes entre los mismos para el periodo comprendido entre Enero/04-Enero/10. Métodos: se utilizó la metodología de Paasche, y técnicas econométricas de series de tiempo. Resultados: el índice refleja bien el comportamiento observado de los precios y como tal es un buen medidor de la evolución de los mismos, del ingreso, y referencia útil para tomar decisiones de compra-venta de los productores y comercializadores. Aunque la trayectoria de los precios diverge en el corto plazo, existe una relación de equilibrio de largo plazo que los dirige, y ello es indicativo de la eficiencia en la formación de los mismos. De acuerdo con la información empírica disponible, un aumento del 1% en el precio del cebado macho, aumenta el precio del levante en 1.13%; en el corto plazo, las variaciones de precios en meses pasados afectan a los corrientes; el precio del levante causa a lo Granger al precio del cebado, y las desviaciones del equilibrio se corrigen mediante ajustes en el precio del mes siguiente. Conclusiones: El ajuste es bastante lento, se calcula que en aproximadamente siete meses el 50% de una variación del precio del ganado cebado se transmite al precio del levante. Objetivo: construiu-se um índice de pre os ao produtor de gado de corte quando ele estava na etapa de peso sobreano e gordo no departamento de Sucre, Col mbia, e examinaram-se as rela es existentes entre éstas etapas durante o período compreendido entre o día 4 até 10 de Janeiro de 2012. Métodos: utilizando a metodología de Paasche, e técnicas econométricas de series de tempo. Resultados: encontrou-se que o índice reflete bem o comportamento observado dos pre os e é um bom medidor da evolu o dos mesmos, do ingresso, e é uma referencia útil para tomar decis es de compra e venta para os produtores e comercializadores. Embora a trajetória dos pre os seja diferente no curto prazo, existe uma rela o de equilíbrio de longo prazo que dirige o movimento dos pre os, indicando uma eficiência na forma o dos mesmos. De acordo com a informa o empírica disponível, uma varia o de 1% no pre o do gado gordo, aumenta o pre o do gado ao sobreano em 1.13%; no curto prazo, as varia es de pre os dos meses anteriores afetam aos atuais; o pre o do gado ao sobreano causa o Granger ao pre o do gordo, e os desvios do equilíbrio corrigem-se mediante ajustes no pre o do mês seguinte. Conclus es: o ajuste é bastante lento, calcula-se que em aproxi

Abstract: El objetivo de este artículo fue caracterizar la estructura de mercado de las subastas de ganado de levante en las ciudades de Montería y Sincelejo (Colombia). Para ello se utilizaron cuatro indicadores de concentración de las compras: el CR4, el CR8, el índice de Herfindahl (HI) y el índice de Rosenbluth (RI). Los resultados indican que las subastas operan en condiciones muy cercanas a las que los textos de teoría económica llaman competencia perfecta, o competencia operativa, en la teoría de la organización industrial. O objetivo deste artigo foi caracterizar a estrutura do mercado de leil es de gado levantado nas cidades de Monteria e Sincelejo (Col mbia). Para esse efeito, quatro indicadores concentra o de estabelecimentos comerciais: o CR4 e CR8, o índice Herfindahl (HI) e o índice Rosenbluth (RI). Os resultados indicam que operam em condi es leil es próximos aos textos da teoria econ mica chamada concorrência perfeita, ou competência operacional na teoria da organiza o industrial.
