Recently, various authors have examined the relationship between growth in government size and total economic growth. In each case, the authors permitted only a monotonic relationship. This paper examines the issue of a non-linear relationship between growth in government and overall growth in the economy.Government contributes to total economic output in various ways. The provision of Pigovian public goods enhances the productivity of the private sector inputs increasing total output. However, the public decision-making process can result in an inefficient quantity of public goods. The likelihood of this outcome increases with the size of government. Further negative effects are created by the revenue raising and spending mechanisms of government, and the increasing diversion of resources into unproductive rent-seeking activities. The magnitude of these effects is likely to increase with the relative size of government. 相似文献

Conclusions The present study has attempted to artriculate a central issue of Mahäyäna soteriology through an examination of the writings of two Mädhyamika masters, Bhävaviveka and Candrakïrti. The purpose here has been to demonstrate a further criterion for the retrospective designation of their respective philosophies with the terms Svtantrika and Prasangika an exhaustive study of the nature of the Hinayäna wisdom according to the Mädhyamika school would entail an analysis of the writings of many other masters, especially those who produced what has been called the Yogäcära-Mädhyamika synthesis. To attempt to determine the position of Maitreyanätha, for example, on this issue would entail an analysis of the famous Five Treatises (the Dharmadharmatävibhaa, the Madhyäntavibhaga, the Mahayanasutrlamkara, the Uttratantra, and the Abhisamayälamkära) as well as the myriad commentaries on these works. It is possible to speculate briefly here on what the position of Nägärjuna may have been on this issue and then go on to discuss the implications and possible motivations of the views of Bhävaviveka and Candrakïrti. 相似文献

Effects of positional restraint on oxygen saturation and heart rate following exercise 总被引:1,自引:0,他引:1

This report assesses the effects on peripheral oxygen saturation and heart rate that positional restraint induces when a person is prone, handcuffed, and "hog-tied." Peripheral oxygen saturation and heart rate were monitored at rest, during exercise, and during recovery from exercise for 10 adult subjects. The effects of positional restraint produced a mean recovery time that was significantly prolonged. Consequently, the physiological effects produced by positional restraint should be recognized in deaths where such measures are used. 相似文献

Significance of functional and nutritive pulmonary circulation for vital reactions in the form of embolisms 总被引:2,自引:0,他引:2
G Adebahr 《Zeitschrift für Rechtsmedizin》1988,100(1):55-64
The functional and nutritive circulation in the lungs is connected by anastomoses between the pulmonary and bronchial arteries. The anastomoses have the structure of blocked arteries from which arteriovenous anastomoses proceed to the peribronchial plexus. The pulmonary artery is provided with a flow impulse by the anastomoses, and oxygen-containing blood is admixed with the venous blood, thus forming an "aortalization" in the lungs. By diverting the bloodstream, venous blood can reach the bronchial artery. The peculiarities of the lung circulation are important for vital reactions in the form of macro- and microembolisms. Macroembolisms prove the functionality of the system if branches of the pulmonary artery are closed before the arteries are blocked. A hemorrhagic infarction either arises or does not arise, and the hemorrhagic infarction cannot exceed a certain limit. A microembolism is over and above the anastomoses. If the microembolism is greater, pressure in the arteria pulmonaris can cause blood from the pulmonary artery to overflow into the bronchial artery. Because arteriovenous anastomoses arise from the blocked arteries, microemboli can now reach the systemic circulation. Thus, the system described can explain the passage of microemboli into the systemic circulation, avoiding the capillaries of the lungs; on the other hand, larger microembolisms can prove the functionality of the system. 相似文献

Conclusion The housing arbitration system used by Brigham Young University's Housing Arbitration Board (HAB) has been widely used at the school for many years. It has not worked perfectly. Some landlords are critical of the school's laxness in enforcing arbitral awards.In general, students prefer the process over small claims court (chiefly, it appears, because of cost factors). The school administrators prefer mediation over arbitration but recognize that mediation does not always resolve impasses. Legal questions exist about BYU's potential restraint of trade in using the obligatory contracts the school mandates for landlords. The process relies upon persons of goodwill to serve on the tribunals, but has a long enough track record to demonstrate the HAB concept works quite well. Because of annual turnover, the need for training of mediators/arbitrators is always critical. Other universities may well wish to emulate (or modify) the HAB model in resolving their landlord and student-tenant disputes.

Northern Ireland is a bicommunal society in which Protestantsare numerically dominant; Roman Catholics constitute virtuallyall of the remaining population. On the island as a whole, Protestantsare heavily outnumbered; the Republic of Ireland (the "South")has a population that is about 96 percent Catholic. Social segregationof the two northern communities is relatively distinct, andthere is little crosscutting between groups that might lessenbicommunal conflict. A reciprocal relationship exists betweenthe social system and political structures. Northern Irish politicalinstitutions followed the Westminster model, which facilitatedthe political exclusion of Catholics and impeded social as wellas political integration. The bicommunal social structure hasimpeded the development of more accommodating political structures.Geographic issues and external linkages compound the politicalproblem. Northern Irish politics can be viewed as a "dual dyad"in which the United Kingdom and the Republic of Ireland arecritical components. Psychological dimensions of Northern Irishbicommunalism further exacerbate the conflict. 相似文献
