Disorders in the musculoskeletal system have been associated with a high physical workload as well as psychosocial and individual factors. It is however not obvious which of these factors that is most important to prevent. Musculoskeletal disorders in neck and upper extremity was assessed by interview and clinical examination in 79 teachers and 93 assisting nurses, all females. Psychosocial work environment was assessed by questionnaire. The physical workload was recorded by technical measurements of postures, movements and muscular load, in 9 teachers and 12 nurses. The physical workload was lower among the teachers, but they had a more demanding psychosocial work environment. Among the nurses, but not in the teachers, the neck-shoulder disorders were associated with a high body mass index (BMI). The teachers reported neck-shoulder complaints to a higher extent than the nurses, but had much lower prevalence of diagnoses in the clinical examination (12% vs. 25%; POR 0.3 CI 0.1 - 1.2; adjusted for age and BMI). The results suggest that adverse psychosocial conditions among the teachers give rise to a different kind of pain in the neck-shoulder region than from physical overload, troublesome but not as severe as the one afflicting the nurses. 相似文献

In an experimental study two levels of oculomotor load were induced via optical trial lenses. Trapezius muscle activity was measured with bipolar surface electromyography and normalized to a submaximal contraction. Sixty-six subjects with a median age of 36 (range 19-47, std 8) viewed a black and white Gabor grating (5 c/deg) for two 7-min periods monocularly through a 0 D lens or binocularly through -3.5 D lenses. The effect of time was separately regressed to EMG in two different subgroups of responders: a High-Oculomotor-Load (HOL) and a Low-Oculomotor-Load (LOL) group. A linear regression model was fitted on group level with exposure time on the x-axis and normalized trapezius muscle EMG (%RVE) on the y-axis. The slope coefficient was significantly positive in the -D blur condition for only the HOL subgroup of responders: 0.926 + Time(min 1-7) × 0.088 (p = 0.002, r(2)=0.865). There was no obvious sign of this activity to level off or to stabilize. These results suggest that professional information technology users that are exposed to a high level of oculomotor load, during extended times, are at an increased risk of exhibiting an increased trap.m. activity. 相似文献

Most schools in today's Europe have a high percentage of immigrant students. This percentage has increased in typical immigration countries such as Switzerland, Luxembourg, Belgium, Germany, France and the UK. However, this is also true for countries such as Sweden or Spain. Aware of this multicultural picture, in this paper we present the methodological approach of a European Comenius project, "Eurokid", based on the template "Britkid" (see www.britkid.org), which addresses intercultural education and anti-racism. Three countries are involved in the project: the UK, Sweden and Spain. The project is an educational and innovative tool and a learning and teaching resource for students and teachers in secondary schools. How? Through websites where a group of adolescents (minorities and majorities) "meet" and "talk" about issues of acceptance, difference, racism, mixed cultures, (multiple) identitie, and integration. Their "talks" in the three websites--written in each country's language(s) and in English--as well as the characters, are based on original research (via interviews and questionnaires). The project's objectives, content, pedagogical approaches and authentic classroom material, created to facilitate and promote dialogue among minorities and majorities, form the basis of this paper. 相似文献

Lately, social researchers have become increasingly interested and involved in comparative and cross-national research. In part this reflects a growing realisation that key social, economic and political processes are not merely ‘domestic’ but are common across countries and cultures. Although numerous good quality data sets now exist (e.g. the European Social Survey or International Social Survey Programme), in many instances researchers need to design their own bespoke comparative surveys. Such surveys require careful design if they are to produce meaningful data. Herein we introduce, outline and report on one technique which may usefully be employed in order to design better survey items for use in cross-national surveys. 相似文献

People who interact with citizens in their job often have to use discretion when facing complex situations. Research shows that how people understand their job regulates this use of discretion. Yet, little research has conceptualized how group culture shapes these understandings and discretionary actions in real-life citizen encounters. This article addresses this gap with a microsociological theory of group culture. To demonstrate the merits of this theory, I use a sample of 11 interviews and 88 body-worn camera recordings to analyze how ticket inspectors perceive and act in contested ticket-fining events. The analysis identifies two group styles of moral inspection characterized by tight or loose regulation: justice or service. These styles are associated with the two operating teams in a traffic company and influence how inspectors manage contested events with a risk of escalation. I discuss how these findings contribute to the sociology of culture and enhance the understanding of how group culture shapes discretionary actions in citizen encounters. 相似文献
