An investigation on the pay-off to generic competences for core employees in Catalan manufacturing firms

The aim of this paper is to measure the returns to human capital. We use a unique data set consisting of matched employer-employee information. Data on individuals' human capital include a set of 26 competences that capture the utilization of workers' skills in a very detailed way. Thus, we can expand the concept of human capital and discuss the type of skills that are more productive in the workplace and, hence, generate a higher payoff for the workers. The rich information on firm's and workplace characteristics allows us to introduce a broad range of controls and to improve previous research in this field. This paper gives evidence that the returns to generic competences differ depending on the position of the worker in the firm. Only numeracy skills are reward independent of the occupational status of the worker. The level of technology used by the firm in the production process does not directly increase workers’ pay, but it influences the pay-off to some of the competences. JEL Classification: J24, J31

Mouse interleukin-2 receptor alpha gene expression. Delimitation of cis-acting regulatory elements in transgenic mice and by mapping of DNase-I hypersensitive sites.

The alpha chain of the interleukin-2 receptor (IL-2R alpha) is a key regulator of lymphocyte proliferation. To analyze the mechanisms controlling its expression in normal cells, we used the 5'-flanking region (base pairs -2539/+93) of the mouse gene to drive chloramphenicol acetyltransferase expression in four transgenic mouse lines. Constitutive transgene activity was restricted to lymphoid organs. In mature T lymphocytes, transgene and endogenous IL-2R alpha gene expression was stimulated by concanavalin A and up-regulated by IL-2 with very similar kinetics. In thymic T cell precursors, IL-1 and IL-2 cooperatively induced transgene and IL-2R alpha gene expression. These results show that regulation of the endogenous IL-2R alpha gene occurs mainly at the transcriptional level. They demonstrate that cis-acting elements in the 5'-flanking region present in the transgene confer correct tissue specificity and inducible expression in mature T cells and their precursors in response to antigen, IL-1, and IL-2. In a complementary approach, we screened the 5' end of the endogenous IL-2R alpha gene for DNase-I hypersensitive sites. We found three lymphocyte specific DNase-I hypersensitive sites. Two, at -0.05 and -5.3 kilobase pairs, are present in resting T cells. A third site appears at -1.35 kilobase pairs in activated T cells. It co-localizes with IL-2-responsive elements identified by transient transfection experiments.

Ootaxonomic investigation of five Lutzomyia species (Diptera, Psychodidae) from Venezuela

The eggshell fine structure of five sand fly species from Venezuela belonging to the genus Lutzomyia (L. migonei, L. ovallesi, L. absonodonta, L. gomezi and L. panamensis) was examined by scanning electron microscopy. The chorionic sculpturing of L. migonei, L. ovallesi, L. absonodonta and L. gomezi was characterized by series of columns arranged in palisade to form sinuous ridges. In inter-ridge areas, the basal layer was covered with fibrous material. The outer chorion of L. panamensis had a pattern known as "mountain- or volcano-like". The morphology of the posterior pole and aeropyle had a common structure in the five species, with some species-specific characters. The eggshell features of the five species are compared with those of other phlebotomine sand flies.

Home Accident Prevention Strategy

The overall aim of the strategy is “To reduce the number of accidental deaths and injuries in the home.” OBJECTIVES OF THE STRATEGY The key objectives are: • to reduce home accidents, particularly in those most at risk; • to raise awareness of the causes of home accidents and promote effective preventative measures to reduce such accidents; • to promote and facilitate effective training, skills and knowledge in home accident prevention across all relevant organisations, groups and individuals. These objectives will be met through integrated and effective approaches including: • education and information programmes to promote home safety, and promote a change in public behaviour towards home accident prevention; and • the use of evidence based practice, models of good practice, and by evaluating home accident prevention initiatives. OUTCOMES If successful, implementation of this strategy will lead to a reduction in the number of home accidents and contribute to the outcome “reduction in preventable deaths and diseases and improvement in wellbeing” set out in the Northern Ireland Priorities and Budget 2004-2006.

Morphological investigation of Toxoplasma gondii in vivo by a multiple beam interference microscope

A recently developed technique, namely multiple beam interference microscopy, has been applied to investigate the morphology of the parasite Toxoplasma gondii for the first time. The interference pattern obtained from the multiple internal reflection of a T. gondii, sandwiched between a glass plate and a cover plate, was focused on the objective of a conventional microscope. Because of the enhance contrast, several details of sub cellular structure and separating compartments are clearly visible. Details reveal the presence of a nucleus, lipid body, dense granule, rhoptry and amylopectin. The wall thickness of the membrane of the lipid body and the amylopectin is of the order of 0.02 µm and can be clearly distinguished with the help of the present technique. The same parasite has also been examined with the help of atomic force microscopy, and because of its thick membrane, the inner structural details were not observed at all. Sub cellular details of T. gondii observed with the present technique have been reported earlier only by low amplification transmission electron microscopy and not by any optical microscopic technique.

The Executive in its Programme for Government under the theme “Working for a Healthier People” gave a commitment to promoting public safety by reducing the number of injuries and deaths caused by accidents at home, at work and on the road. An overarching strategy for children and young people is also being developed, which will set out the vision, values and underlying principles, including general safety, for all children and young people and the long-term goals to make that vision a reality.

European Home and Leisure Accident Surveillance System report for Ireland 2001

EHLASS provides a harmonised approach throughout the EU to facilitate the analyses of intercountry differences in modes and distributions of home and leisure accidents. EHLASS contributes to the formulation of EU policies and initiatives on accidents and product safety. EHLASS is the only source of detailed information on home and leisure accidents in Ireland. Some general information is available through the Hospital In-Patient Enquiry (HIPE) system but this concentrates on medical diagnoses rather than on specific causes of accidents.This report is the eleventh national EHLASS report for Ireland.
