Expansión de la temporalidad y erosión de la relación de empleo estándar en España: ¿La irrupción de un nuevo paradigma de relación de empleo?
2018
Desde la década de los ochenta el mercado de trabajo español ha venido caracterizado por la persistencia de unas tasas muy altas de temporalidad hasta convertirse este en un problema crónico de la sociedad española, que, además, no ha tenido -en cuanto a magnitud- parangón en el resto de países de la UE. Las diferentes fórmulas de contratación temporal creadas e incentivadas por la vía normativa en un proceso de “reforma laboral permanente” se han convertido, en conjunción con otros factores entre los que destaca la utilización empresarial de los contratos temporales en el límite de la legislación, cuando no en claro fraude de ley, en una efectiva vía para la segmentación laboral y una clar…
Talent Management
2012
Talent management is a new concept in the scientific literature, but not in the practitioner arena. In this sense, this chapter underlines the powerful perspective of talent management integrating practices from organizations and providing a scientific approach. Some previous results from different research are expressed in relation to strategy and organizational performance. Talent Management is clearly a concept close to high performance work system, with the difference of a more strategic approach. More than practices are goals for the organization to achieve excellence at work. So Talent Management is clearly linked with a strategic approach to the organization in order to attract, deve…
Corporate Social Responsibility: A Survey of the Italian SA8000 Certified Companies
2005
Today’s society requires companies to act more and more effectively for the general good, by respecting human rights and the environment. Innovative and enlightened companies try to meet this need through the adoption of several initiatives. Accordingly, the International Standard Organisation is now working on attempts to unify these initiatives and to formulate an internationally recognised standard, providing guidance to companies on social responsibility. Currently the SA8000 international standard is the most often used tool – based on Corporate Social Responsibility (CSR) philosophy – which guarantees the respect of fundamental workers’ rights. Since 2003, Italy holds the world record…

Moving Ahead from Assessments to Actions by Using Harmonized Risk Assessment Methodologies for Soil Degradation
2010
Almost all developed countries use risk assessment methodologies (RAMs) for the evaluation of risks related to soil degradation, viz. soil organic matter decline, erosion, landslides, salinization and/or compaction. However and for various reasons, seldom the use of such RAMs seldom results in actual measures to combat soil degradation in practice. In this study the current status of RAMs in EU-27 was evaluated and factors hampering the implementation of action plans were explored. To do so we used a so-called risk assessment chain, which describes the five successive steps of any risk assessment for soil threats viz., (1) notion of the threat, (2) data collection, (3) data processing, (4) …
Concise review of interrill erosion studies in SE Spain (Alicante and Murcia): erosion rates and progress of knowledge from the 1980s
2005
From the 1980s onward studies on interrill soil erosion were intensified in SE Spain. The main achievements of the research carried out in the field areas of Alicante and Murcia concern: first, (1) the estimation of erosion rates directly in the field under a wide range of methodologies, different scales and different environmental conditions; (2) estimations based on existing models, such as the USLE, carried out for different subcatchments of the Segura and Júcar catchments; and (3) other parametric and physical event-based models have also been calibrated and validated. Second, the progress of the knowledge in understanding erosion mechanisms. New and reviewed concepts regarding mainly h…
Modifications in Water Resources Availability Under Climate Changes: A Case Study in a Sicilian Basin
2014
Climate variability due to the greenhouse effect has important implications on hydrological processes and water resources systems. Indeed, water availability, quality and streamflow are very sensitive to changes in temperature and precipitation regimes whose effects have to be fully considered in current water management and planning. International literature proposes several models, attempting to assess accurately the available water resources under stationary and changing climatic conditions at different spatial and temporal scales. In order to assess the potential impacts of climate change on surface and groundwater resources water availability in a Southern area of Italy, a conceptual h…
Role of Modeling Uncertainty in the Estimation of Climate and Socioeconomic Impact on River Water Quality
2012
AbstractClimate is one of the most important factors leading to changes in the hydrologic and environmental characteristics of river basins. When considering water quality, the natural factors should be weighed against anthropogenic factors (such as urbanization, increased population, and higher water demand) that may increase or decrease the effect of climatic modifications. Any prediction of future climatic and anthropogenic scenarios is affected by uncertainty and the modelling tools that are used for evaluating their impact on receiving water bodies. The present paper is aimed at investigating the complexity of such analyses and the uncertainty related to future impact predictions based…
The regional park of the Nebrodi Mts. (Sicily): a contribution to an integrated groundwater management
1998
The Nebrodi Park, located in the north-eastern sector of Sicily, is of particular environmental and scientific interest. This is due to the morphological heterogeneity of the protected region that presents a wide variety of landscapes and ecosystems. In spite of the recent efforts of the Regional Government and Municipalities, environmental resources, especially groundwater, risk progressive depauperation and pollution. In this paper, the authors consider the hydrogeological karst unit of Monte Traura-Rocche del Crasto, the most productive in the Nebrodi belt (zone B of the regional park). This unit is underexploited and needs a careful hydrogeological study in order to supply coastal aquif…
A GIS-Based Model for the analysis of an urban flash flood and its hydro-geomorphic response. The Valencia event of 1957
2016
Summary Flash floods are recurrent events around the Mediterranean region. Extreme episodes activate hydro-geomorphic high-intensity processes with low frequency. In urban environments, the complexity becomes higher due to the existence of very quick-response runoff. However, immediate recovery works remove the urban marks. After a short time both the significance and magnitude of the hydro-geomorphic event become completely unrecognizable. Nevertheless, these episodes generate extensive documentation which is testimony of the processes in almost real time. It is necessary to exploit this source typology in order to draw flood sketches when events far in time may lack a sufficiently rich da…
