Piecework versus Timework in British Wartime Engineering
Piecework versus Timework in British Wartime Engineering The British engineering industry experienced extreme production and employment pressures during the rearmament period that preceded the Second World War and in the early war years. Did it react by placing a greater emphasis on incentive-compatible payment methods? This paper examines the relative employment and wage effects on pieceworker...
متن کاملLow prevalence of byssinotic symptoms in 12 flax scutching mills in Normandy, France.
The concentrations of airborne dust and bacteria were determined in 12 flax scutching mills and in two milk processing plants in Normandy, France. A total of 308 of 340 flax workers and 111 of 113 milk processors volunteered to answer a respiratory questionnaire. Personal exposure to airborne dust in the scutching mills varied from 22.2 mg/m3 to 144 mg/m3 and areal concentrations from 8.92 mg/m...
متن کاملMassive-star supernovae as major dust factories.
We present late-time optical and mid-infrared observations of the Type II supernova 2003gd in the galaxy NGC 628. Mid-infrared excesses consistent with cooling dust in the ejecta are observed 499 to 678 days after outburst and are accompanied by increasing optical extinction and growing asymmetries in the emission-line profiles. Radiative-transfer models show that up to 0.02 solar masses of dus...
متن کاملDust exposure in manual flax processing in Egypt.
Manual flax processing originated in Egypt in 2 000 BC. In the present study a representative sample of the workers involved in this trade, where flax is processed in small workshops or homes, was examined, and their dust exposure was evaluated. The study showed that workers handling and processing flax are exposed to high concentrations of dust; the levels of dust at hackling and combing are c...
متن کاملRespiratory response in simultaneous exposure to flax and hemp dust.
Zu§kin, E., and Valic, F. (1973). British Journal of Industrial Medicine, 30, 375-380. Respiratory response in simultaneous exposure to flax and hemp dust. The effect of exposure to high concentrations of mixtures of hemp and flax dust was studied in 124 workers in two textiie mills (mill A: 65-70% hemp and the rest flax, mean dust concentration 13 9 mg/m3; and mill B: about 35% hemp and the re...
