Economic valuation of landscapes: combining landscape ecology and environmental economics methodologies.

Aim of the paper is to outline an integrated methodology for deriving economic values of the different landscape components. Our approach integrates landscape ecology principles and non-market valuation methodologies. Firstly, we identify landscape types and quantify their attributes with ‘metrics’ (i.e., objective components) and use discrete choice experiments to elicit the public’s preferences for these landscapes and their attributes (i.e., subjective components). As a case-study we use the Peninsula of Sorrento in Italy, which is a unique Mediterranean landscape, which is increasingly endangered by urban sprawl and decline of traditional farming. Results show the economic value of different types of landscapes and, importantly, provide convincing support for an interdisciplinary approach for landscape valuation

Ecological characteristics and new competitiveness strategies in fresh vegetables market

The intense process of internationalisation of the food market is giving rise to new competitive scenarios. The growth of market shares by new export countries, along with other consumer and retailer's issues impose different marketing policies for agri-food products. In particular, a wider awareness of consumers for environmental and health issues is modifying the structure of demand for fresh products. In the past, the country of origin and a convenient quality/price ratio were the main strategic strengths for gaining and maintaining international market shares . Nowadays market shares are gained by moving towards new product attributes, namely environment friendliness and food safety. This paper aims to suggesting new and more successful marketing strategies. The case study is the German market of cherry tomatoes. An analysis of German consumer preference was performed on stated choice data. Results provide interesting insights. Product attributes related to the environment are found to be relevant. As these are defined as 'faith' attributes, we speculate that German consumers refer to product origin country as a proxy of its environmental aspects. Two separate competitive segments emerge, one with a higher level of environmental quality (Germany and Italy), and Turkey, Spain, France and Holland. Finally, results point out how policies need to be redesigned and focused on new and more complex issues expressed by consumers in modern and developed markets marketing.competitiveness strategies, cherry tomato German market, environmental friendly, fresh vegetables, Mixed Nested Logit, International Relations/Trade, Marketing,

An integrated methodology for the evaluation of organic farming support scheme environ-mental effects supported by Geographic Information Systems (GIS)

Within the current Common Agricultural Policy (CAP) framework, Member States are obliged to evaluate their respective Rural Development Plans (RDPs). The aim of the evaluation is to verify the efficiency and efficacy of the implementation process, particularly as concerns the objective of integration of environmental issues in the agricultural policy. In this context, a more comprehensive evaluation methodol-ogy is needed. Particularly, the spatial structure of the territory the intervention targets must be inte-grated in the analysis. Geographic Information Systems (GIS) have been widely considered a useful tool to encompass the spatial aspects in the evaluation process. GIS, in fact, are able to perform spatial analysis as well as estimate quantitative indicators referred to different geographic frames. In this short paper we propose a GIS-based analysis of the effects of organic farming aid scheme implementation and we report the results of an application of such a methodology

Reposicionamento labial convencional versus modificado na abordagem combinada do tratamento do sorriso gengival: revisão narrativa

O sorriso gengival é uma condição que pode provocar grande desconforto estético. As etiologias que levam a este tipo de problema são diferentes assim como as diferentes opções terapêuticas. O aumento da demanda dos últimos anos levou a um desenvolvimento de técnicas menos invasivas para o tratamento do sorriso gengival. O objetivo desta revisão narrativa é comparar a técnica de reposicionamento labial convencional com as técnicas modificadas, que podem ser associadas a outros tratamentos (toxina botulínica e alongamento coronário) em planos de tratamentos com abordagem combinada.The gingival smile is a condition that can cause great aesthetic discomfort. The etiologies that lead to this type of problem are different as are different therapeutic options. The increase in demand in recent years has led to the development of less invasive techniques for the treatment of gingival smile. The aim of this narrative review is to compare the conventional lip repositioning technique with the modified technique, which can be associated with other treatments (botulin toxin and coronary elongation) in treatment plans with a combined approach

An open data index to assess the green transition - A study on all Italian municipalities

This study introduces a municipality transition index based on open data and green transition principles. The Municipality Transition Index provides data and a succinct measurement of municipal attributes as defined by green policies at national and local level. We identify four dimensions of interest and 18 key performance indicators, defined at municipality level, and measure factors that directly and indirectly influence the green transition, with a focus on the Green Deal vision embraced by the European Union. The robustness and meaningfulness of the index is tested on a dataset covering all 7904 Italian municipalities. Our results show that computation of the MTI on this sample produces a bell-shaped distribution, suggesting strong geographic disparities and a significant difference between cities, towns and rural areas. The results show the need for policies and tools tailored at municipal level and provide information for practitioners, policy makers and experts from academia, useful for designing tools to underpin investment planning in the framework of the recent National Recovery and Resilience Plan issued by the Italian government. This may be particularly useful for enhancing green-transition-enabling factors that may differ across regions, helping policymakers to promote a smooth and fair transition by monitoring the performance of municipalities as they address the challenge

Ions and water transmembrane transport in nervous and testicular cultured cells in low gravity conditions

Aim of the present study was to investigate on the possible alter- ations induced by on ground modeled microgravity on ion-water transport proteins at cellular level. For the purpose we used astrocytes, C6 line, neurons (NT2 line from human teratocarci- noma) and testicular cells (germ cells, Sertoli cells, and Leydig cells; primary cultures from trypsinised prepuberal pig testes). Modeled microgravity was achieved by a desktop 3D Random Positioning Machine, cultures were kept rotating for 30’, 1h and 24h. After 30’, immunopositivity for the antibodies to Na+/K+ATPase and Na+/K+/Cl- co-transporters was greatly diminished, the plasma membrane appeared to be altered, and the mitochondria inner cristae were disrupted. Immunostaining to the antibody to the water channel aquaporin 4 was very bright. After 1h at random rotation immunostaining for the heat shock protein Hsp27 was visible, After 24h, immunostaining for the ion transport proteins was again like that of the controls,plasma membrane and the mitochondria were again normal. Immunostaining for aquaporin 4 become again similar to that of the controls. We conclude that low gravity induces only tran- sient alterations in the cell’s transmembrane ion-water trans- port: the cells are able to adapt to the gravity vector changes in few hours

Free-Surface Flow Simulations with Smoothed Particle Hydrodynamics Method using High-Performance Computing

Today, the use of modern high-performance computing (HPC) systems, such as clusters equipped with graphics processing units (GPUs), allows solving problems with resolutions unthinkable only a decade ago. The demand for high computational power is certainly an issue when simulating free-surface flows. However, taking the advantage of GPU’s parallel computing techniques, simulations involving up to 109 particles can be achieved. In this framework, this chapter shows some numerical results of typical coastal engineering problems obtained by means of the GPU-based computing servers maintained at the Environmental Physics Laboratory (EPhysLab) from Vigo University in Ourense (Spain) and the Tier-1 Galileo cluster of the Italian computing centre CINECA. The DualSPHysics free package based on smoothed particle hydrodynamics (SPH) technique was used for the purpose. SPH is a meshless particle method based on Lagrangian formulation by which the fluid domain is discretized as a collection of computing fluid particles. Speedup and efficiency of calculations are studied in terms of the initial interparticle distance and by coupling DualSPHysics with a NLSW wave propagation model. Water free-surface elevation, orbital velocities and wave forces are compared with results from experimental campaigns and theoretical solutions

A DEM approach for simulating flexible beam elements with the Project Chrono core module in DualSPHysics

This work presents a novel approach for simulating elastic beam elements in DualSPHysics leveraging functions made available by the coupling with the Project Chrono library. Such numerical frameworks, belonging to the Meshfree Particle Methods family, stand out for several features, like complex multiphase phenomena, moving boundaries, and high deformations which are handled with relative ease and reasonable numerical stability and reliability. Based on a co-rotating rigid element structure and lumped elasticity, a cogent mathematical formulation, relying on the Euler–Bernoulli beam theory for the structural discretization, is presented and applied to simulating two-dimensional flexible beams with the discrete elements method (DEM) formulation. Three test cases are presented to validate the smoothed particle hydrodynamics-based (SPH) structure model in both accuracy and stability, starting from an equilibrium test, to the dynamic response, and closing with a fluid–structure interaction simulation. This work proves that the developed theory can be used within a Lagrangian framework, using the features provided by a DEM solver, overtaking the initial limitations, and hence applying the results of static theories to complex dynamic problems.Xunta de Galicia | Ref.
