Extended work periods.
A literature review of 105 studies on the effects of extended daily working hours was conducted. Potential negative effects of extended working hours are discussed: More accidents on the job; more accidents off the job; reduced duration and quality of sleep due to moonlighting; sleepiness; reduced alertness; fatigue; adverse effects on performance; prolonged toxic exposure; adverse effects on h...
متن کاملAdapted Progressive Isoinertial Lifting Evaluation for determining Lifting capacity
Weight of the load and its characteristics is considered to be the important risk factor for low back disorders (LBD) among manual materials handlers. Determining weight of the load and the amount of load a person can lift is important in minimizing the incidence of LBD. Among various methods like isometric, isoinertial and isokinetic, isoinertial approach of lifting evaluation is best as it is...
متن کاملDoes Malleolus non-Lifting Tympanoplasty have any Advantage Over Malleus Lifting Technique?
Introduction: In order to achieve a higher success rate for tympanoplasty, different techniques have been developed, and a wide variety of grafting materials have been developed. One of the techniques currently receiving considerable attention involves not lifting the remaining of eardrum from the malleus and embedding the graft underneath in order to repair the eardrum correctly in its origina...
متن کاملConsumption Patterns Over Pay Periods
This paper establishes a theoretical framework to characterise the optimal behaviour of individuals who receive income periodically but make consumption decisions on a more frequent basis. The model incorporates price uncertainty and imperfect credit markets. The simulated numerical solution to this model shows that weekly consumption functions are ordered such that the functions within the pay...
