The same high labor supply elasticity that characterizes a representative family model with indivisible labor and employment lotteries also emerges without lotteries when self-insuring individuals choose interior solutions for their career lengths. Off corners, the more elastic the earnings profile is to accumulated working time, the longer is a worker’s career. Negative (positive) unanticipate...

The title of this book expresses a well known truth ^hich may not always have been sufficiently appreciated ?y the various medical departments which deal with ^dividual units of the family. The work described here ls based on research carried out through the co-operation ?f the faculties of Public Health, Medicine and Psychiatry ln association with the medical social worker, the case Worker, an...

Infants in the hand washing–alone group were less likely than those in the control group to develop omphalitis (relative risk, 0.7), though mortality rates did not differ. Moreover, neither infection risk nor mortality risk was reduced in analyses that compared the two hand-washing groups with the two other groups. The researchers note that the study's limitations include the use of community h...

toluene diisocyanate (tdi) is an imperative chemical substance used in the production of polyurethane foams, elastomers, paints and coatings that cause a variety of health problems in workers who are exposed in work places. this study aimed to determine the asthma symptoms and serum specific ige levels in tdi exposed workers and comparing the results with healthy control group.all the plants th...

Financial transfers provided to individuals from friends and family members in times of need are difficult to measure, yet the role of private, informal assistance in determining economic outcomes is important to identify, as private transfers may serve as a source of insurance for households. In this paper, I use longitudinal data from the Panel Study of Income Dynamics (PSID) to measure the e...

What kind of housing choices will families with two paid workers make? Will higher income families still tend to live further away from the central city, as is the current U.S. pattern, leaving one worker (presumably the male) with a longer home-to-work commute, the other worker (presumably the female) with the shorter worktrip commute? Or will two salaried worker households locate homes, or ev...

This paper describes an expansion of a multi-period worker assignment model for a lean production cell that produces a single product family. The hypothetical cell operates eight hours per day, twenty days per month and has six workers performing ten tasks. The model assigns the workers to tasks and determines the levels of additional training that may be necessary to meet customer demand, qual...

Ironworkers frequently perform heavy lifting tasks in teams of two or four workers. Team lifting could potentially lead to a higher variation in peak lumbar compression forces than lifts performed by one worker, resulting in higher maximal peak lumbar compression forces. This study compared single-worker lifts (25-kg, iron bar) to two-worker lifts (50-kg, two iron bars) and to four-worker lifts...
