Equidad y educación de la primera infancia en la agenda educativa mundial

2019

Resumen (descriptivo): El presente trabajo se inspira en la necesidad de abordar un análisis de la equidad en la etapa de educación infantil desde un enfoque holístico, para contribuir al debate actual sobre la importancia de la equidad en la nueva agenda educativa y sus metas para la primera infancia. Parte de fundamentos del estudio teórico de la equidad en educación desde un enfoque holístico que permita aplicar este análisis a la educación de la primera infancia en las sociedades iberoamericanas, en aras de aportar una perspectiva más amplia en la discusión de sus logros y desafíos. Finalmente, este entendimiento posibilita la interpretación de los límites y posibilidades de los objetiv…

Sapotrophical development of fusarium graminearum : respective role of different natural habitats of the fungus in the wheat infectious process in Bu…

2012

Fusarium Head Blight (FHB), mainly caused by the fungal species Fusarium graminearum, is one of the most important disease altering wheat crops in Burgundy. Moreover the plant-pathogen interaction leads to the production of mycotoxins potentially toxic for humans and animals.The only alternative to date to prevent the development of the disease is to control the saprotrophic development of F. graminearum in its natural habitat, i.e. weeds, soil and crops residues. Due to the trend of reduced tillage, special attention should be paid to the role of crop residues in the survival and development of F. graminearum.Two approaches were chosen to better understand the saprotrophic development of F…

Corruption and Organised Crime Signalling Indicators for Foreign Investors as Applied to Eastern European Countries

2021

The former communist countries in Central and Eastern Europe and, implicitly, their economies, went through specific and sometimes asymmetric developments since the fall of the “iron curtain” at the end of the 1980s. During those years, they faced many challenges to create a secure and predictable economic environment for individuals and businesses, local or foreign. We propose a framework that considers legal, social, and economic indicators which can be used by foreign investors to make wise and efficient business decisions. Our main purpose is to expand the traditional economic analysis framework and enrich it with new institutional and societal indicators from the social, quality of lif…

An Exploratory Study of Financial Performance in CEE Countries

2020

Our research investigates the performance of companies from Central and Eastern European (CEE) countries in the period after the Global Financial Crisis of 2007-2009 with the aim of identifying the driving factors behind accounting- and market-based performance. We include in the analysis companies from various industries in CEE countries that are European Union members and we study their performance between 2008-2016 over the following areas of performance:  liquidity,  solvency and indebtedness, operational profitability, global performance (through Return on assets and Return on equity), returns available to shareholders and market-based performance (through price/book value and Tobin Q …

Bryophytes as ecological indicators in the beech woods of sicily

2019

Beech woods, which have in Sicily one of the southernmost places of their distribution area, are localized in the mountain belt of North and North-Eastern Sicily, at an altitude of 1300-1900 m, reaching 900 m on the Peloritani. They are referred to the priority habitat 9210*, according to the Natura 2000 network of the European Union. Beech woods settle on different soils, such as incoherent sandy volcanic (Etna), calcareous or silico-arenaceous (Madonie) and clayey-schistose soils (Nebrodi and Peloritani). Bryophytes are considered important components of forestry ecosystems. Many of these organisms are specific to particular types of microhabitats and sensitive to changes such that specie…

Fuzzy Quantification of Common and Rare Species in Ecological Communities (FuzzyQ)

2020

Abstract1. Most species in ecological communities are rare whereas only a few are common. This distributional paradox has intrigued ecologists for decades but the interpretation of species abundance distributions remains elusive.2. We present Fuzzy Quantification of Common and Rare Species in Ecological Communities (FuzzyQ) as an R package. FuzzyQ shifts the focus from the prevailing species-categorization approach to develop a quantitative framework that seeks to place each species along a rare-commonness gradient. Given a community surveyed over a number of sites, quadrats, or any other convenient sampling unit, FuzzyQ uses a fuzzy clustering algorithm that estimates a probability for eac…

Quantifying the Indicator Power of an Indicator Species

2009

Biodiversity indicator species are needed for classifying biotopes and sites for conservation, and a number of methods have been developed for determining indicator species for this purpose. Nevertheless, in addition to site classification, there is sometimes a need to define an indicator species that indicates the occurrence of another species. For example, when a species of interest (target species) is difficult to detect or identify, a reliable indicator species can function as a tool that saves time and money. We derived a method that provides a quantitative measure of the indicator power (IP) of an indicator species for the target species or any species assemblage. We calculated the me…

Response of benthic foraminifera to heavy metal contamination in marine sediments (Sicilian coasts, Mediterranean sea)

2011

To examine the suitability of benthic foraminifera and their test deformations as bioindicators of pollution in coastal marine environments, we studied foraminifera and metal concentrations in 72 marine sediment samples, collected from the inner shelf along the Sicilian coast (Gulfs of Palermo and Termini) and on the south-eastern coast of Lampedusa Island. These areas are characterised by different environmental conditions. On the basis of pollution sources and foraminiferal assemblages, we recognised different zones in the Gulf of Palermo. The most polluted zones showed high metal concentrations, and low diversity of benthic foraminifera with species typical of stressed environments. By c…

Assessing the sustainability of water companies: A synthetic indicator approach

2016

Performance indicators (PIs) are essential in the benchmarking process used to rate and rank water companies. However, a set of individual PIs does not provide a holistic assessment of company performance from multiple perspectives. A multidimensional evaluation of the performance of water companies can be achieved by aggregating the PIs into a synthetic indicator. Although the concept of sustainability involves economic, environmental and social criteria, most of the previous studies have not considered these three dimensions simultaneously. This paper discusses a process of indicator aggregation using two approaches based on multi-criteria decision analysis to evaluate and compare the sus…
