Extent and persistence of soil water repellency induced by pines in different geographic regions
2018
The extent (determined by the repellency indices RI and RIc) and persistence (determined by the water drop penetration time, WDPT) of soil water repellency (SWR) induced by pines were assessed in vastly different geographic regions. The actual SWR characteristics were estimated in situ in clay loam soil at Ciavolo, Italy (CiF), sandy soil at Culbin, United Kingdom (CuF), silty clay soil at Javea, Spain (JaF), and sandy soil at Sekule, Slovakia (SeF). For Culbin soil, the potential SWR characteristics were also determined after oven-drying at 60°C (CuD). For two of the three pine species considered, strong (Pinus pinaster at CiF) and severe (Pinus sylvestris at CuD and SeF) SWR conditions we…

The School Programme: A Key Link between Contextual Influence and School Development
2018
ABSTRACTThis paper is designed to contribute to the discussion on how to conceptualise and study contextual influence in local school development. We propose a theoretical framework and an empirical illustration to supplement former research on rural school research. Focusing on what the school perceives as important in its community may explain why schools are different, based on the concept that the place where the school is located has its own expectation structures. This interaction between school and place creates the concept of the school programme, representing the role of teacher expectations within the school and the teachers’ encounter with the expectation structures of the specif…
Does one size fit all? The impact of cognitive skills on economic growth
2016
Les Documents de Travail de l'IREDU, n°2016-1; This paper tests for heterogeneous effects of cognitive skills on economic growth across countries. Using a new extended dataset on cognitive skills and controlling for potential endogeneity, we find that the magnitude of the effect is about 60 per cent higher for low-income countries compared to high-income countries, and it more than doubles when low TFP countries are compared to high TFP countries. There are also marked differences across geographic regions. Using data on the share of the population with advanced and minimum skill levels, our results also indicate that high-income countries should focus on increasing the number of high skill…
Some European green roof norms and guidelines through the lens of biodiversity : do ecoregions and plant traits also matter?
2018
Abstract Green infrastructure and in particular green roofs are crucial to meet the challenge of sustainable urbanisation fostered by the current European Research and Innovation agenda. Several documents were issued in the last decades in Europe for regulating the design, construction and up-keep of roof greening. In particular, the actual German guidelines have been widely adopted as a reference basis for green roof design and regulation worldwide, because of its exhaustiveness and proven building- and landscaping tradition. With the aim to assess the effectiveness of green roof guidelines and norms in supporting plant and soil biodiversity in different ecoregions, and particularly of the…
Calidad de vida en Argentina: percepciones macro y micro-sociales
2012
El artículo presenta los resultados de un estudio desarrollado en Argentina que diferencia laopinión de ciudadanos acerca de su calidad de vida, para dicho estudio se tomaron en cuentados zonas geográficas específicas, la Ciudad Autónoma de Buenos Aires y los Partidos delGran Buenos Aires. Se midió el nivel de satisfacción con la calidad de vida en el país y con lacalidad de vida personal a partir de la utilización de diferentes instrumentos: escala de satisfacción con la calidad de vida en el país (ESCVP), escala de satisfacción con la vida (SWLS)y encuesta de áreas vitales.
Foro de educación
2014
Dada la riqueza y la diversidad social, cultural y educativa de América Latina, esta región geográfica se presenta como un escenario privilegiado para el aprendizaje y el desarrollo humanos de educadores de todo tipo, muy especialmente para los educadores sociales. De ahí que distintas universidades españolas hayan firmado convenios de cooperación con universidades latinoamericanas y establecido acuerdos de colaboración con organizaciones locales para que estudiantes de ambos lados del Atlántico puedan realizar prácticas. Este artículo se centra en el Programa Específico de Movilidad Internacional de la Facultat de Filosofía i Ciències de l’Educació de la Universitat de Vàlencia, describien…
Stress with parents and peers: how adolescents from 18 nations cope with relationship stress.
2015
We investigated how adolescents from five regions around the world perceived and coped with parent- and peer-related stress.The study comprised N = 4957 adolescents (mean age of 15.2 years) from 18 countries.The study used self-report measures for stress perception and coping style.Across countries, adolescents perceived parent-related stress to be considerably greater than peer-related stress. They coped less actively with parent-related stress than with peer-related stress. Significant differences emerged with respect to geographic region and key demographic indicators. Adolescents from Eastern European and Western countries had generally quite low levels of stress. Adolescents from South…
Research trends in retailing: a comparative approach Spain-Europe-USA
2002
This paper describes the evolution of research in retailing comparing three different geographic regions: Spain, Europe and the United States. Working on the basis of a bibliographic review of the academic research published between 1996 and 2000 together with a content analysis, the results of this study reveal a heterogeneous evolution in nine thematic areas related to the field of retailing. The differences are particularly noticeable when comparing those of Europe with those of the USA, and reveal different areas of interest over the last five years.
Global patterns of polycyclic aromatic hydrocarbons (PAHs) in soil
2007
Abstract Recent findings suggest a higher natural contribution to PAH concentrations in soil than previously thought. I hypothesized that the PAH pattern in soil is dominated by two main types, which are indicative of background conditions on the one side (i.e., by biological and diffuse PAHs) and a strong impact by atmospheric deposition of anthropogenic emissions on the other side. To test this hypothesis, concentrations of 20 PAHs in 225 topsoil samples from 12 geographic regions were evaluated. The Σ20PAHs concentrations ranged between 4.8 and 186,000 μg kg− 1. In soils with low concentrations of Σ20PAHs, naphthalene (NAPH), phenanthrene (PHEN), and perylene (PERY), together defined as …
