This paper analyzes the incentive effects of pollution taxesversus pollution permits for a budget oriented Government.Pollution permits are analyzed as durable goods, and apollution tax is seen as being equivalent to leasing outpollution permits. First, a general model is developed, andthen four stylized types of Government are discussed (abenevolent dictator, a pure Leviathan, a green and a business-friendly Government). We show that all types of Governmentprefer a pollution tax system, but this regime is notnecessarily the best in social welfare terms. The intuition isthat a tax or leasing system makes it easier for theGovernment to credibly commit to the budget maximizing levelof pollution permits which is good for Government revenues,but not necessarily for social welfare.  相似文献

Dimensions of Politics in the European Parliament   总被引:1,自引:0,他引:1  
We investigate the dimensionality of politics in the European Parliament by applying a scaling method to all roll-call votes between 1979 and 2001 in the European Parliament. Contrary to most existing studies using these methods, we are able to interpret the substantive content of the observed dimensions using exogenous measures of national party policy positions. We find that the main dimension of politics in the European Union's only elected institution is the classic left-right dimension found in domestic politics. A second dimension is also present, although to a lesser extent, which captures government-opposition conflicts as well as national and European party positions on European integration.  相似文献

Human DNA profiles can be obtained from fly artifacts (feces and regurgitant) when a fly has been feeding on biological material, sometimes 2 years after deposition. Morphological similarity between artifacts and spots of unaltered biological material make it difficult to distinguish between them, and presumptive and confirmatory forensic tests are unreliable in making the distinction. Knowing possible artifact locations will assist investigators in recognizing where DNA contamination might occur. Flies were released into a house with human blood available under a variety of different climatic and lighting conditions. The location of flies and artifacts was recorded after 72 h. It was found flies may move toward warm or well‐lit areas and deposit artifacts there, but artifacts were predominantly located around food sources and were often found in low positions. Factors such as ambient temperature, and the proximity of light and food sources, had an impact on where artifacts were deposited.  相似文献

The degree of banking efficiency is of key importance as this has significant implication on the stability of financial systems and ultimately impacts on an economy. In this paper, we extend the existing literature by measuring the degree of bank efficiency in ten frontier African countries. We also attempt to analyse the determinants of banking efficiency in the sample countries. We employ a bank-level panel data set over the period 2008–2012 to measure banking efficiency in a two-stage procedure. In the first stage, we use the Data Envelopment Analysis technique to estimate technical, pure technical and scale bank efficiency. In the second stage, we use Simar and Wilson (J Econom 136:31–64, 2007) truncated bootstrapping approach to analyse the determinants of banking efficiency. The results of our analysis show that, to a greater extent, banks in the countries studied have efficient banking sectors. The results of truncated regression indicate that bank size is negatively related to banking sector efficiency while the degree of risk is positively related bank efficiency. Overall, the present study provides empirical information that may be used to guide future financial reform policies in the Frontier African countries.  相似文献

Report on a case in which an 8-year-old girl was injured on the left anterior thoracic wall by two shots fired by her 14-year-old cousin from a soft-air pistol (replica of mod. 17 make Glock, cal. 6 mm, solid plastic bullets); the projectiles caused two skin lesions, both reaching into the subcutis. The results of our own shooting tests with 2 different soft-air pistols and the injuries seen in our case confirm that soft-air pistols may cause penetrating soft-tissue injuries when fired from a short distance.  相似文献

The stellate bullet entrance wound is one of the facultative features of a contact shot. For the formation of a star-shaped wound two factors are of special importance: first, an extensive bony support underlying the skin in the entrance region, and second, a strong propellant charge of the cartridge fired. Contact shots to the precordial region usually do not cause stellate entrance wounds, even if high-powered rifle ammunition is used. In the reported case, an injury pattern was observed that was not in line with normal findings and seemed confusing at first. Following a suicidal gunshot to the chest from a sawed-off carbine 98a (cal. 8 x 57 Js), a 4.5 cm wide, gaping bullet entrance wound with radiating tears was found. Instead of the usual pocket, the anterior thoracic wall showed a fist-sized area of destruction with extensive undermining of the subcutis. Not far from the entrance hole, a rib fragment had become displaced retrogradely thus perforating the skin from the inside out. The unusual pattern of findings could be explained by the fact that the barrel had been sawed off: as a result of this manipulation, a considerable part of the propellant charge had been converted outside the barrel, i.e. in the initial section of the bullet path.  相似文献

Biological stains can be difficult to detect at crime scenes or on items recovered from crime scenes. The use of a versatile light source may assist in their detection. The ability of Polilight to locate potential semen, saliva, and blood stains on a range of substrates and at different dilutions was tested. We also tested the use of Polilight in comparison with conventional chemical-based presumptive screening tests such as acid phosphatase (AP), Phadebas, and luminol, often used in casework for detecting potential semen, saliva, and blood stains, respectively. The Polilight was able to locate stains that were not apparent to the naked eye. The color of the material on which a stain is deposited can have an effect on the detectibility of the stain. The Polilight was found to be comparable with the AP and Phadebas tests in terms of its sensitivity. In a comparative study between the AP test and Polilight on 40 casework exhibits, one false-negative result was observed when using the Polilight. On a series of mock casework exhibits it was determined that the Polilight can be used successfully to locate saliva stains for DNA analysis. The sensitivity of luminol for detecting potential bloodstains was greater than that of Polilight; however the Polilight has particular application in instances where a bloodstain may have been concealed with paint. Overall, the Polilight is a relatively safe, simple, noninvasive, and nondestructive technique suitable for use in forensic casework.  相似文献

Using the idea of regime formation and cooperation in international political economy as a guide, this paper assesses the first stage (Cross-cceptance) of implementing the New Jersey stateplanning process as an attempt to construct a base of mutually shared norms and interests between state and local governments in the area of land use planning. The conclusion is that the first round of implementation was instrumental in building norms and consensus-especially in the face of strong resistance to state planning from the policy environment. The main reason for the effectiveness of the Cross-Acceptance process was that it brought local, county and state officials to a forum where they were able to discuss areas of consensus and discord.  相似文献

In a factorial design, impulsive and reflective children played video games with aggressive or nonaggressive themes. Interpersonal aggression and aggression toward inanimate objects were assessed in a free-play setting and interpersonal aggression was assessed during a frustrating situation. Results indicated that subjects who played the video game with aggressive content exhibited significantly more object aggression during free-play and more interpersonal aggression during the frustrating situation than youngsters who played nonaggressive video games. Aggressive behavior was unaffected by cognitive tempo.  相似文献
