The aim of this paper is to formulate new and more precise predictions regarding behavioral reactions to distributive and procedural injustice via insights from resource theory. The three theories share focus on discrepancies between actual and ideal states of existence as well as on psychological and behavioral reactions to discrepancy. But they also differ from each other in their conceptualizations and theorizing about these matters. Equity theory conceptualizes discrepancy as a perceived mismatch between inputs and outcomes; multiprinciple distributive justice and procedural justice theories view discrepancy as a mismatch between expected and applied distribution and procedural rules, respectively. Resulting feelings of inequity/injustice may trigger attempts to restore justice. Within the framework of resource theory, discrepancy concerns an inappropriate match between the nature of the provided and received resources. This leads to frustration which, in turn, may trigger attempts at retaliation. Limitations of the theories are discussed, with particular focus on their inability to match specific discrepancies with appropriate behavioral reactions. Behavioral predictions are based upon established congruence between behavioral reactions and violated procedural rules as well as type of inequity, as determined via their respective resource isomorphism. Limitations of the present integration attempt are discussed.  相似文献

Uropepsinogen (PGA) was isolated and purified from human urine using a column chromatography series. The purified PGA was injected into a rabbit and a PGA-specific antibody was obtained. PGA isozymogen in human urine could be detected reproducibly by immunoblotting using this antibody after isoelectric focusing electrophoresis (IEF) on polyacrylamide gels. This technique may prove to be useful in the genetic study of PGA polymorphism.  相似文献

During the 13-year period of 1973-1985, at least 329 deaths in Jordan resulted from poisoning by pesticides. Organophosphates were the major compounds incriminated in 93.6% of the cases. The annual mortality rate compared with that of other countries is relatively high, and was 5.97%, 17.35%, and 2.6% per 1 million people in 1973, 1979, and 1985, respectively. The annual mortality rates due to suicidal and accidental poisoning are 61% and 35.3%, respectively: 74% of the accidentally poisoned group are children less than 10 years, while 60.7% of the suicides are 15-24 years of age. To minimize such high mortality rates from pesticide poisoning, Jordan needs to adopt more protective measures by rigorous regulation.  相似文献

We report an autopsy case of infant death due to heat stroke. On a winter day, a 52-day-old female baby was placed under a Japanese electric foot warmer with a coverlet (kotatsu) on an electric carpet warmer in a heated room at home. After about 5 h, the mother noticed that the baby was unconscious and took her to a hospital. Spontaneous respiration, however, was already absent, and the pupils were dilated. The trunk was hot; body temperature was 41.3 degrees C. The skin of the whole body was dry. Autopsy revealed second-degree burn injuries on the left side of the face and the dorsum of the left hand. Numerous marked petechiae and ecchymoses were found in the thymus (capsule and parenchyma), pleurae (visceral and parietal), pericardial cavity (internal and external surfaces), epicardium, and beneath the serosa at the origin of the aorta. In addition, there was congestion in various organs, edema in the brain and lungs, and hemorrhage in the lungs. Histopathologically, macrophages without hemosiderin granules were present in the alveoli. When the heating conditions at the accident were reproduced experimentally, the temperature in the electric kotatsu warmer rose to 50-60 degrees C. Thus, we concluded that misuse of the electric kotatsu caused heat stroke in this infant.  相似文献

Polymorphism of PGD was investigated in bloodstains, organ tissues, dental pulps, hair roots and semen by isoelectric focusing. This technique provided much higher resolution of PGD isoenzymes than starch gel electrophoresis. Phenotyping was possible from bloodstains for 5 weeks, from organ tissues (except pancreas) for 1-3 weeks, from dental pulps for 2 weeks and from hair roots for 2 weeks when they were stored at room temperature. The method is simple, rapid, reliable and therefore useful in medicolegal individualization of bloodstains, organ tissues, teeth and hairs.  相似文献

道路交通事故制动拖印可以判断肇事车辆的逃逸方向,推算肇事车辆制动前的车速,判断肇事车辆的接触点,但正确无误地认定有一定的困难。道路交通事故现场勘查人员应根据制动拖印的明显的特征,较长的刮痕、积聚物等痕迹物证来正确认定和准确测量。  相似文献

Two young men and a 17-year-old girl gathered in order to take methamphetamine, the quantity of which remained unknown. After a short time one of the men died on the scene; the other man, who was alcoholized in addition to having taken methamphetamine, fell over a railing from a height of several metres and suffered severe injuries before dying. The girl, who left for home by taxi, collapsed and died in a hospital about 2 hours later. Methamphetamine was detected in the blood of all three people. The autopsy results and the toxicological findings are reported and discussed with reference to the literature data.  相似文献
