Side-bets and reciprocity as determinants of organizational commitment among correctional officers 总被引:1,自引:1,他引:0
Organizational commitment is a particularly salient characteristic of the prison work climate due to the stressful working conditions and high rate of turnover among correctional officers nationwide, yet little is known about the factors that predict the level of organizational commitment among officers. Becker's (1960) side-bets hypothesis predicts greater commitment among those who develop additional investments in the job that would be lost with a change of jobs, and the reciprocity hypothesis predicts greater commitment among those who feel they are well treated, supported, and respected by the organization. This study used a sample of 546 correctional officers to examine the relative effects of side bets and reciprocity on two components of organizational commitment—affective commitment and continuance commitment. The results of a multivariate OLS regression analysis indicated that reciprocity had a greater effect than side bets on affective commitment but that side bets had a greater effect than reciprocity on continuance commitment. These findings, which provide partial support for the side-bet hypothesis and strong support for the reciprocity hypothesis, are discussed in terms of the link between organizational commitment and other work-related behaviors. 相似文献

Results obtained from three commercial immunoassay kits, Abuscreen, TDx, and EMIT, commonly used for the initial test of urine cannabinoids (and metabolites) were correlated with the 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (9-THC-COOH) concentration as determined by GC/MS. Correlation coefficients obtained based on 26 (out of 1359 total sample population) highly relevant samples, are 0.601 and 0.438 for Abuscreen and TDx. Correlation coefficients obtained from a parallel study on a different set of 47 (out of 5070 total sample population) highly relevant specimens are 0.658 and 0.575 for Abuscreen and Emit. The immunoassay concentration levels, that correspond to the commonly used 15 ng/ml GC/MS cutoff value for 9-THC-COOH, as calculated from the regression equations are 82 ng/ml and 75 ng/ml for TDx and EMIT and 120 ng/ml and 72 ng/ml for Abuscreen manufactured at two different time periods. The difference of these calculated corresponding concentrations provides quantitative evidence of the reagent specificity differences. 相似文献

Hazards of mattresses, beds and bedding in deaths of infants 总被引:2,自引:0,他引:2

Of 52 infants who had died suddenly and were referred to autopsy, nine had lain on adult water beds for the first time; five had died as a result of accidents; two had died on water beds; two were in beds with widely spaced slats; and one had died as a result of strangulation. Three deaths were due to overlying. Three other infants had been placed on sheepskin rugs for the first time and were found dead shortly thereafter. These infants ranged in age from 2 to 9 months, except for a severely mentally retarded nine-year-old with spastic paraplegia. We believe that a general warning should be issued concerning water beds and that soft bedding should not be used for infants. Infants should not be placed unattended or left to sleep on water beds; only beds recommended for infants should be used. Overlying of a young infant is most likely to occur on a water bed, or if the parent is obese or has consumed alcohol. 相似文献

Three questions relevant to insanity decisions were examined: (a) What informational cues are weighed most heavily in the attribution of criminal responsibility? (b) How do verdict forms influence these attributions? And (c) How do individuals' beliefs about insanity and responsibility influence decision making? Undergraduate subjects (n=181) responded to vignettes portraying an act by a mentally disordered defendant. Psychiatric jargon was avoided, so that attributions were not a function of diagnostic terminology. It was found that, under the traditional scheme of not guilty by reason of insanity (NGRI) vs. guilty, level of mental disorder (schizophrenia vs. personality disorder) was the primary determinant of insanity decisions. Also, insanity judgments were more likely to be made for acts performed without planful intentionality. Under the alternative scheme of NGRI vs. guilty but mentally ill (GBMI) vs. guilty, mental disorder still controlled NGRI verdicts; a bizarre act increased the likelihood of a GBMI over a guilty verdict; and the GBMI verdict option reduced markedly the proportion of psychotic defendants found NGRI and the proportion of personality disordered defendants found guilty. There were no significant differences between diagnostic groups in the likelihood of being found GBMI. Most subjects preferred to utilize the GBMI option as a compromise verdict even in the face of very severe mental illness. Attitudinal data revealed considerable variation in agreement with the classic moral logic of the insanity defense and accounted for a significant amount of the variance in insanity decisions. The implications for both social policy and future research are discussed. 相似文献

Death associated with inadvertent hydrocodone overdose in a child with a respiratory tract infection
A 3-year-old child died of the combined effects of a bacterial superinfection and a relative overdose of hydrocodone prescribed for a cough due to a presumed viral respiratory tract infection. This case illustrates the importance of evaluating the effects of prescribed medication in assessing the cause and mechanism of death in children dying suddenly of presumed natural disease. 相似文献
