Input: Consider Input: Abstract: Occurrence sampling was used in the main production area of a university residence hall foodservice to measure and analyze work functions involved in entree production and to determine time requirements for entree categories. Sixteen entrees were investigated: seven single-item, six combination, and three roast. Data collection took place in a period of 5 days over a 2-week span. A total of 3,891 observations was recorded during 297 labor hours. Results of the study indicated 59.2% of the total labor time was spent in direct work, 23.3% in indirect work, and 17.5% in delays. The preparation work function represented the highest proportion of labor time for both single-item and roast entrees, but prepreparation consumed the greatest amount of time for combination entrees. Mean labor minutes per serving for the 16 entrees were 0.9, with a range of 0.4 to 3.5. Mean labor minutes per serving for combination entrees were 1.4, which was the highest among the three groups; range was from 0.4 to 3.5 minutes per serving. For single item entrees, mean minutes per serving were 0.6, with a range of 0.4 to 0.8. Roast entrees, had a mean time requirement per serving of 0.5 minute, with a range of 0.4 to 0.6.

Input: Consider Input: Abstract: Bilateral optic atrophy is reported in two patients who, although they were long-standing users of the leaves of Catha edulis, had chewed larger quantities than usual. Since the leaves of this plant are used widely throughout its native area as the source of a mildly stimulant narcotic, the effect in these cases may be an idiosyncratic reaction to an unusually large dose.

Input: Consider Input: Abstract: Of the nearly 600 Vietnam War American prisoners of war (POWs), 332 were United States Air Force flyers who had suffered maltreatment, confinement, and boredom for months to years. We examined four coping styles of USAF POWs related to successful/unsuccessful coping and resistance stance during captivity and cognitive integration of the prisoner experience after repatriation. Findings indicate that no coping style is clearly associated with an increased risk of postrepatriation psychiatric morbidity. Postrepatriation MMPI scales indicate personality differences between individuals in the various coping groups.
