Minority type matters : ethnic diversity and tolerance in 29 European democracies

Past research has shown that having a large population of ethnic minorities beyond the neighborhood level arouses intolerance in the majority. However, this paper presents the argument that the effect of minority size on tolerance depends on minority type: the less subject the minority is to negative stereotyping, the more favorable the effect that minority size has on tolerance. In this study, a hierarchical linear model was applied to a dataset on advanced and emerging democracies in Europe. The analysis shows that when the duration and level of democracy are controlled for, ethnic tolerance was associated positively with native minority size and negatively with foreign population size.

ASSESSMENT OF ASPEN AND NORTHERN HARDWOODS EXTENT IN THIRTY THREE COUNTIES OF UPPER/LOWER MICHIGAN

The importance of the United States' wood and wood byproducts as biomass feedstocks is increasing as the concern about security and sustainability of global energy production continues to rise. Thus, second generation woody feedstock sources in Michigan, e.g., hybrid poplar and hybrid willow (Populus spp.), are viewed as a potential source of biomass for the proposed biofuel ethanol production plant in Kinross, MI. It is important to gain an understanding of the spatial distribution of current feedstock sources, harvesting accessibility via the transportation infrastructure and land ownerships in order to ensure long-term feedstock extent. This research provides insights into the current extent of aspen and northern hardwoods, and an assessment of potential for expanding the area of these feedstock sources based on pre-European settlement conditions. A geographic information system (GIS) was developed to compile available geospatial data for 33 counties located within 150 miles of the Kinross facility. These include present day and pre-European settlement land use/cover, soils, road infrastructure, and land ownerships. The results suggest that a significant amount of northern hardwoods has been converted to other land use/cover types since European settlement, and the "scattering" of aspen stands has increased. Furthermore, a significant amount of woody biomass is available in close proximity to the existing road network, which can be effectively utilized as feedstock. Potential aspen and northern hardwoods restoration areas are identified in the vicinity of road networks which can be used for future woody feedstock production.

Representaciones sociales del trasplante de médula ósea, la quimioterapia y la cirugía oncológica en población general colombiana

Las representaciones sociales son una construcción de significados que las personas otorgan a un objeto en este caso el tratamiento oncológico. En el mundo, el cáncer es una enfermedad de alta prevalencia y sus tratamientos suelen generar numerosos efectos secundarios, pero a la vez es el recurso médico disponible para controlar la enfermedad. Este estudio cualitativo tuvo como objetivo analizar las representaciones sociales del tratamiento oncológico en población colombiana. Participaron voluntariamente 20 personas seleccionadas por conveniencia. Se realizaron entrevistas abiertas y se analizaron los resultados a través del análisis temático y se interpretaron con base en la teoría de las representaciones sociales. Los resultados indicaron que las personas representan el tratamiento oncológico convencional, predominantemente como quimioterapia, generadores de sufrimiento, miedo, alto costo físico, emocional y económico; así como una apuesta en la que la ganancia puede ser la prolongación de la vida o la remisión. Se discuten los resultados y sus implicaciones.

O ensino tipo “e-learning”: alguns comentários

The scientific and technological development, has brought the possibility of people having access to a large volume of information, especially via the Internet. However, this information has to be filtered, due to danger of assimilating wrong and unreliable information. The so-called teaching type "e-learning" adopted by some schools, seems to have solved these problems. This paper focuses on some problems associated with the teaching system of "e-learning" and the difficulty to adapt it to certain areas of knowledge. The advantages of the courses in "bi-learning" are presented as well as some of the drawbacks associated with this type of education.
