Did nineteenth century technology reduce demand for skilled workers in contrast to modern technology? I obtain direct evidence on human capital investments and the returns to skill by using micro-data on individual weavers and an engineering production function. Weavers learned substantially on the job. While mechanization eliminated some tasks and the associated skills, it increased returns to...

A study was undertaken to identify the work stressors among male and female weavers (N=516) in powerloom and handloom and examine the association of work stressors with the prevalence of work related musculo-skeletal disorders (MSDs). Physical and psychosocial stresses of work, job diagnostics, hazards of workplace, working environment and MSDs prevalence were assessed. There is high prevalence...

OBJECTIVES We investigated general working conditions in the carpet manufacturing industry and assessed the health risk factors of weavers working in this industry. MATERIALS AND METHODS Noise level, light intensity, temperature and humidity were measured with the help of sound level meter, lux meter and thermohygrometer, respectively at the workplace and the result were subjected to One Way ...

BACKGROUND Musculoskeletal disorders (MSDs) are a common problem among carpet weavers. This study was undertaken to introduce affecting personal and occupational factors in developing the number of MSDs among carpet weavers. METHODS A cross-sectional study was performed among 862 weavers in seven towns with regard to workhouse location in urban or rural regions. Data were collected by using q...

Observations of web spinning behavior in Costa Rican Dinopis sp. reveal the same behaviors synapomorphic for orb weavers: specifically frame, radius, non-sticky spiral construction, and sticky spiral construction, as well as more detailed motor patterns. Dinopids are therefore highly derived orb weavers, although the behavioral data do not conclusively indicate whether they are more closely rel...

purpose : to determine the effect of carpet weaving on refractive errors methods : in this cross sectional study, carpet weavers and non-weavers in the normal population of mashhad were regarded as exposed and non-exposed groups, respectively. a carpet weaver was a person who wove carpets 7 hours a day for at least 2 years. the non-weavers group was selected from the population of mashhad throu...

the prevalence of varicose veins was studied in 1742 male weavers in iran by completing a specially designed questionnaire and medical examination. to show the effect of occupation on the prevalence of the disease, similar study was conducted on a group of 1661 food- processing workers. the over- all prevalence of the disease in the weavers (26.12%) was significantly higher than the similar rat...

Carpet weavers suffer from musculoskeletal problems mainly attributed to poor working postures. Their posture is mostly constrained by the design of workstations. This study was conducted to investigate the effects of 2 design parameters (weaving height and seat type) on postural variables and subjective experience, and to develop guidelines for workstation adjustments. At an experimental works...

the carpet industry developed various types of respiratory and musculoskeletal disorders, eyesight problems,  carpal tunnel syndrome and skin problems. healthy behavior of carpet weavers is not in a desirable level. we recommended appropriate interventions such as health service, education improvement and advocacy for promoting healthy behaviors of carpet weavers.

Purpose: To determine the relationship between refractive errors and ocular components values in carpet weavers Methods: Refractive errors and ocular components values were investigated in carpet weavers at Mashhad city in Iran. After selection of samples, the individuals who had ophthalmic and systemic disease effective on the refractive errors were excluded from the study. Refractive errors a...
