Investigative bodies and other observers have attributed much of the blame for the 1985 MOVE catastrophe in Philadelphia to ineffective management by the city's previously successful mayor, W. Wilson Goode. Goode's behavior toward the disruptive extremist group followed two patterns, both paradoxical: protracted delay followed by excessive haste, and arms-length action that contrasted sharply with his usual hands-on management style. Drawing on the theory of decisionmaking developed by Irving Janis and Leon Mann, this paper suggests that both paradoxes resulted from unresolved decisional conflicts that impeded responsible and rational handling of the problem. The case points to the value of devoting more attention to the psychology of decision-making in educating present and future public managers. 相似文献

Alcoholism and drug addiction affects the entire family. At least 22 million Americans have been raised in an alcoholic environment. Parental alcoholism and/or addiction can have profound emotional and psychological scars on the children. These homes are often characterized by emotional and or physical insecurity, loneliness, terror and inconsistency. The children from these homes often are extremely insecure have low self-esteem, and have a variety of emotional problems. Adolescents from addictive homes are over-represented in juvenile court as status offenders, delinquents and abuse and neglect cases. This article will discuss this issue and implications for the juvenile justice system and personnel working with these youth 相似文献

Abstract A simulation model that mirrors the actual practices of lenders in setting qualification requirements for mortgage loans is used to assess the impact of permanent buydowns and buyups on the maximum sale price that buyers can afford. Buydowns are reductions in the coupon rate traded off against higher discount points; buyups are the reverse. Although buydowns have little effect on afford ability, buyups can have significant effects. Their potential is largely unrealized, however, because of the call risk to lenders of loans carrying premiums. The authors propose a “discount recovery” provision, which would be similar to a prepayment penalty except that the payment upon prepayment would be tied to the amount of the discount foregone by the lender. This would protect lenders against call risk, giving them every reason to offer buyups as a way of expanding demand. 相似文献

Correctly assessing heart weight can be critical at postmortem examination. The current international guidelines advocate using the short-axis method in dissecting the heart and the heart weighed when the blood is emptied. However, it did not specify at what point the heart should be weighed or how the blood should be emptied. This study compared heart weights at three different time points during the heart examination (immediately after dissecting out of the pericardial sac with blood still in chambers, blood washed/removed from heart chambers without the heart opened, and the heart completely opened, blood emptied, and pad dried). This was to illustrate the variation in measurement and potential errors when the heart is weighed at different time of dissection. The results show that there were statistical and clinical significant differences between the heart weights at each weighing points. We recommend the heart to be completely dissected with any blood and residual washing/rinsing water emptied before being weighed. Although performed in this study, the effect of pad drying the heart on heart weight was not explored and was a limitation in this study. 相似文献
