This article examines the recent development of urbanized areas in Belgium and endeavours to measure the space consumed by some of the important human activities: industrial operations, main arteries, housing and urban functions. Notwithstanding a considerable lack of data, the gravity of the situation in Belgium is clear : since 1929, the amount of urbanized area has more than doubled, and, in 1970, the proportion of national territory which was urbanized (28 %) was far higher than in any of the neighbouring countries. It is therefore essential to control the use of land by means of a dynamic policy in country planning and development. The waste of land must be stopped by promoting the concentration of activities in specific centres, by keeping the majority of functions in the heart of the urban network, by assisting the use and re-use of available sites and by controlling any new developments, particularly housing schemes.

The first part is an analytical study based on an analysis of cadastral information. It presents facts and recent evolutionary processes of land use in Wallonia, especially agriculture, forest, waste land and urbanized areas. The information is based on the municipality scale. The paper draws a compartmentalization of Wallonia: in 1992, urbanized areas represented over 20% and 40% in the urban-industrial trench and in Walloon Brabant, spilling area for Brussels population. In Ardennes, Loraine and Fagne Famenne, Forest prevailed occupying over 40% of the land. Agriculture was the main land used over 70% on low loess plateaux and with over 55% especially in Condroz and Central Ardennes. There was a slow decrease of agriculture between 1982 and 1992, usually with less than 10% for a third of the region. Forest erratically fluctuated between -5% and +5%. On the contrary urbanized areas grew everywhere with peaks around Liege, in Walloon Brabant and along motorways. It was the result of both residential urbanization and the standard increase of land use per inhabitant. The analysis shows that, during the seventies, peaks of urbanization coincide quite well with demographic evolution typology. The second part is a continuation of the preceding analytical study. It presents typology and evolution synthesis in order to divide Wallonia into districts and analyses some mechanics especially urbanization and land policy. The analytical maps lead to the building up of two types of municipalities: urban and country land use municipalities. Within the country type, five subtypes have been characterized upon the agriculture and forest combinations. Urbanization mechanics are responsible for the schematic division into two parts by a line, the south border of Condroz and Herve plateau. Urbanization concerns first the urban-industrial trench and Walloon Brabant. Hainaut is an forests also divide Wallonia between the north and the south. The agricultural areas are first victims of the urbanization progress. [less ▲]

The aim of this paper was to use a parametric stochastic frontier approach (coming from the economic literature) to explore the impact of the concept of activity (taken in a broad sense: i.e., including both professional and non-professional activities) on the constitution and the care of cognitive reserve among the European population aged 50 and up. For this purpose, we use individual data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe) performed in 2004. The advantages of this survey were (1) it included a large population (n = 18,623) geographically distributed throughout Europe; and (2) it simultaneously analyzed several dimensions (physical and mental health, mobility, occupational activities, socioeconomic status, etc.). Our results confirm the positive impact of occupational activities on the cognitive functioning of elderly people. These results are discussed in terms of the prevention of cognitive aging and Alzheimer’s disease, and more particularly of retirement policy issues. [less ▲]

This paper investigates the relationship between the concept of activity (including both professional and nonprofessional) and cognitive functioning among older European individuals. In this research, we used data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe), and a measurement approach known as stochastic frontier analysis, derived from the economic literature. SHARE includes a large population (n . 25,000) geographically distributed across Europe, and analyzes several dimensions simultaneously, including physical and mental health activity. The main advantages of stochastic frontier analysis are that it allows estimation of parametric function relating cognitive scores and driving factors at the boundary and disentangles frontier noise and distance to frontier components, as well as testing the effect of potential factors on these distances simultaneously. The analysis reveals that all activities are positively related to cognitive functioning in elderly people. Our results are discussed in terms of prevention of cognitive aging and Alzheimer’s disease, and regarding the potential impact that some retirement programs might have on cognitive functioning in individuals across Europe.

Background. Formal studies on stress in anaesthetists have usually measured stress through mental or physiological indicators. When using this approach, one must be careful not to confuse the effects of stress or outcome variables and the sources of stress or antecedent variables. To date, it seems from the literature that there is no clear evidence of a common pattern of physiological effects of stress for all the sources of stress. Furthermore, work characteristics such as job satisfaction, job control and job support may moderate the effects of stress. Methods. We measured the effects of stress together with the sources of stress and job characteristics, using self-reported questionnaires rather than physiological indicators in order to better diagnose stress in anaesthetists. Results. The mean stress level in anaesthetists was 50.6 which is no higher than we found in other working populations. The three main sources of stress reported were a lack of control over time management, work planning and risks. Anaesthetists reported high empowerment, high work commitment, high job challenge and high satisfaction. However, 40.4% of the group were suffering from high emotional exhaustion (burnout); the highest rate was in young trainees under 30 years of age. Conclusions. Remedial actions are discussed at the end of the paper. [less ▲]

There have been few formal studies on stress in veterinary surgeons and, in the rare studies available, stress is not examined jointly through the levels of job strain and job engagement, the sources of stress in the issue of work environment and the work-home interference. The authors’ goal in this study was to analyse job engagement, job strain, burnout, work-home interference and job stress factors among 216 Belgian veterinary surgeons. Rural practice was compared to small animal and mixed activity. The mean job strain and job engagement level in veterinary surgeons was not higher than what we found in other working populations. However, 15.6 % of the group were found to be suffering from high burnout. Rural practitioners had a lower level of job engagement than small animal veterinary surgeons. These small animal practitioners had a lower level of job strain than the mixed practitioners. The level of burnout did not differ significantly across the three types of activity. In comparison to other Belgian and Dutch workers, veterinary surgeons perceived more negative workhome interference. Bovine and mixed practitioners were the most concerned with this problem. The two most important sources of stress reported by bovine practitioners were relations to farmers and working time management (including emergencies and availability). [less ▲]

CS31A is a K88-related non-fimbrial adhesin first described on Escherichia coli strains isolated from diarrhoeic and septicaemic calves. In this report, CS31A antigen was screened by immunological methods and confirmed by PCR among bovine E. coli isolates. In addition, CS31A-producing strains were characterized with respect to different fimbrial antigens, O-serogroup and other properties related to virulence. Faecal or tissue specimens of 100 diarrhoeic or septicaemic calves and 27 older cattle with different pathologies from 71 outbreaks or individual cases that occurred in Buenos Aires province, Argentina, were examined. CS31A + E. coli strains were isolated from 21 (21.0%) calves from 16 outbreaks or individual cases. No CS31A + E. coli was detected in samples from cattle more than 1 year old. Fimbriae F5, F41, F17a and F17b were not detected among the CS31A-producing strains. Three (14.3%) of the CS31A+ E. coli strains expressed the F17c fimbria. All of the 21 isolates exhibited at least one property of septicaemic strains (resistance to serum, production of aerobactin or colicins) but none of them demonstrated heat-stable enterotoxigenic activity. CS31A + E. coli isolates belonged to 10 serogroups, more commonly O8, O7, O17 and O21. The results obtained here confirm the worldwide distribution of CS31A antigen in bovine E. coli strains. However, CS31A + or CS31A + /F17c + E. coli were less frequently isolated than they were in North hemisphere countries. [less ▲]
