Despite successive military regimes, state and local governmentsin Nigeria have been able to engage in limited forms of foreignaffairs activity. both directly abroad and indirectly throughinstitutions of the national government. The trend since independencehas been to make foreign affairs an exclusive responsibilityof the federal government. Generally, though, the military regimeshave been better able than the civilian governments to limitconstituent diplomacy. Under the Third Republic, therefore,state and local governments are likely to assert themselvessomewhat more in foreign affairs than they have recently.  相似文献

This paper argues that corruption is a product of self-aggrandizement; of unrealistically low remuneration which makes it impossible for public servants to live within their legitimate means; and of a closed political system which inevitably tends to exclude aggregated interests'. Corruption leads to loss of much needed revenue and human talent for development, distorts priorities for public policy, and shifts scarce resources away from the public interest. The mutual distrust that results among the different sections of society, and the growth of despondency in the general public, are incompatible with the requirements for successful public policy. The main theme running through the paper is that political instability, corruption and underdevelopment are mutually reinforcing. The paper finally outlines certain measures that need to be taken in order to clear the path for sustained growth and development.  相似文献

Blood ethanol profiles were determined in experiments with healthy volunteers after they had drunk beer. When 330 ml of light beer (1.8% w/v ethanol) was consumed in 5 min by four men and four women, the average peak blood-alcohol concentration (BAC) reached was 8 mg/100 ml (range 2-11). After nine men had drunk 660 ml of beer (3.0% w/v or 3.6% w/v ethanol) in 25 minutes on an empty stomach, the average peak BAC was 32 mg/100 ml (range 26-44) and 37 mg/100 ml (range 23-54) respectively. When the same two beers were consumed by another nine men together with a meal, the peak BAC was 24 mg/100 ml (range 20-29) and 28 mg/100 ml (range 20-39) respectively. The peak BAC occurred earlier when beer was ingested together with food; mean 32 min (range 30-50) compared with 41 min (range 30-70) with an empty stomach. The rate of disappearance of alcohol from blood (beta-slope) was 12 mg/100 ml/h in the fed state and 15 mg/100 ml/h when subjects were fasted. The apparent volume of distribution of ethanol (Vd) was 0.65 l/kg (SD 0.07) for the empty stomach condition but exceeded unity when beer was ingested together with food. It seems that part of the dose of alcohol when consumed with food never reaches the systemic circulation.  相似文献

Criminologists have long debated the issue of how to define crime, and hence, the scope of criminological inquiry. For years, some critical criminologists have argued for expanded definitions of crime that include harmful behaviors of the state that may not be officially defined as criminal. Other critical criminologists have argued that existing legal frameworks may be used to study varieties of state crime, and that defining the harmful actions of the state as criminal is important to help mobilize public support for their control. In this paper, we first trace the historical development of these two perspectives, and then offer a tentative solution to the seeming tension between these two perspectives.  相似文献

This article explores the different and sometimes conflicting explanations of the success of the collective enterprises (town–village-enterprise) in China during the first phase of transition (1979–1995). It is argued that explanations, relying on cultural variables are not sustainable and this for two reasons. First, the importance of the collective enterprise is shrinking while the private sector is clearly on the rise. Second, other factors, referring to characteristics of the local and central political, administrative and economic environment, in which the Chinese enterprise has to (had to?) operate, provide for a sufficient explanation of the peculiar structure of the Chinese collective enterprises. These enterprises are seen as the result of ?bureau-preneurship’ because local bureaucrats were integrated in their management in order to pre-empt predatory behaviour and to facilitate the relationships with the central institutions. The article contributes to the property rights’ theory of the firm as it analyses an empirically very important case in which firms with unclear property rights and structures, apparently not conducive for incentives, might still be the most efficient option.  相似文献
