Motywy zachowań jednostki jako mikroekonomiczny kontekst działań zespołowych

Galata S.

Ekonomia Menedżerska

2007

nr 2

71-82

W artykule przedstawiono jeden z najważniejszych - zdaniem autora - czynników kształtujących zachowanie ludzi w procesach pracy. Czynnikiem tym jest motyw działania, a pierwszym etapem jego powstawania jest ludzkie sumienie. Prezentując poglądy na ten temat napotykane w literaturze, autor pokazuje ich mizerne, często sprzeczne ze sobą uzasadnienia.

The article discussed the most important factor witch has a big impact on behaviour of people in process of work. The factor is motive for action which is initiated by a human conscience. By presenting the views found in literature, the author shows their poor and often contradictory arguments.

Thirst and Work Capacity of Older People in a Hot Environment

Marszałek A.

International Journal of Occupational Safety and Ergonomics

2000

Zeszyt Specjalny

135--142

In a hot environment, especially during exercise, the main role of thermoregulative mechanisms is to dissipate excessive heat from the body. The most effective way of heat dissipation is sweat production and its evaporation off skin surface. Intense sweating results in a considerable loss of water and electrolytes. There are some results that indicate lower thirst of older men than young ones in response to a hot environment and osmotic stimuli. Our studies conducted in men of different ages exposed to a hot environment indicated that there were no significant differences in rectal temperature (Tre) or heat storage (S) among groups at rest. Lower Tre and lower S in older men with higher physical capacity for their age than in young ones with average physical capacity was shown. However, in all the experiments significantly lower thirst in older men than in the young was indicated. Special attention should be paid to fluid replacement among workers in a hot environment because of lower thirst and lower hydration of older men. These individuals may be exposed to dehydration risk during prolonged exercise, despite the possibility to tolerate heat strain as well as young ones. Further studies are necessary because of some diversity in the meaning of the results.
