However, many agencies often do not have the resources or expertise to harness fully the benefits this data offers. A free to use, scalable traffic crash hot spot detection tool was developed to aid law enforcement agency decision makers, statewide to the local municipality level. The tool was developed to identify crash hot spots algorithmically with </span><span style="font-family:Verdana;">a range of customizable parameters based on location, date and time, and</span><span style="font-family:Verdana;"> crash factors, enabling quick, dynamic queries. These capabilities provide the ability for law enforcement agencies to conduct “what if” analyses and make data-driven allocation decisions, placing officer resources where they are most needed. The two-step algorithm first identifies potential hot spots based on </span><span style="font-family:Verdana;">crash density and then ranks each hot spot using a standardized z-score </span><span style="font-family:Verdana;">measure of relative significance. To test the viability of the tool, a pilot was conducted identifying 27 hot spots across Wisconsin where targeted enforcement was then deployed. Despite officer skepticism, results from the pilot found officers at sites targeted for speeding and seatbelt violations were nearly twice as likely to initiate traffic stops compared to non-targeted hot spots. Empirical Bayes before-and-after crash analyses found fatal and injury crashes reduced significantly by nearly 11% during the months with targeted enforcement, while property damage crashes and total crashes were unchanged. Overall, the results show the algorithm can identify hotspots where, coupled with targeted enforcement, traffic safety improvements can be made.展开更多

This is esp...countries, and emphasizes that the application of the rules in force represents the weak point of systems in which the competition policy awareness is much needed but still anchored at a rudimentary stage. This is especially evident when considering that, although such laws have been built up following the European Union model as regards to the forbidden practices, and the US system-with its combination of monetary fines and criminal approach-for the sanctions, the establishment of a legal environment “friendly competition” is far from effective enforcement. After providing an overview of the competition laws passed by the six GCC members, the paper highlights that, notwithstanding the wide arsenal of legal tools to curb possible anticompetitive practices made available under the national regimes, in all countries role and powers of the competition authorities are somewhat underrated. Due to such generalized lack of implementation, the article underlines the need for effective enforcement standards accompanied by a joint harmonized action against illegal competition to be undertaken at regional level in order to facilitate the flow of commerce, and strengthen the economy in the GCC marketplace.展开更多

Studies on efficiency of wildlife law enforcement in the protected areas are limited. This study analyzed economic efficiency of wildlife law enforcement in terms of resource used and output generated using three different protected areas (PAs) of Serengeti ecosystem namely Serengeti National Park (SENAPA), Ikorongo/Grumeti Game Reserves (IGGR) and Ikona Wildlife Management Area (IWMA). Three years (2010-2012) monthly data on wildlife law enforcement inputs and outputs were collected from respective PAs authorities and supplemented with key informant interviews and secondary data. Questionnaire surveys were conducted to wildlife law enforcement staff. Shadow prices for non-marketed inputs were estimated, and market prices for marketed inputs. Data Envelopment Analysis (DEA) was used to estimate economic efficiency using Variable Return to Scale (VRS) and Constant Return to Scale (CCR) assumptions. Results revealed that wildlife law enforcement in all PAs was economically inefficient, with less inefficiency observed in IWMA. The less inefficiency in IWMA is likely attributed to existing sense of ownership and responsibility created through community-based conservation which resulted in to decrease in law enforcement costs. A slacks evaluation revealed a potential to reduce fuel consumption, number of patrol vehicles, ration and prosecution efforts at different magnitudes between studied protected areas. There is equal potential to recruit more rangers while maintaining the resting time. These finding forms the bases for monitoring and evaluation with respect to resource usage to enhance efficiency. It is further recommended to enhance community participation in conservation in SENAPA and IGGR to lower law enforcement costs. Collaboration between protected area, police and judiciary is fundamental to enhance enforcement efficiency. Despite old dataset, these findings are relevant since neither conservation policy nor institution framework has changed substantially in the last decade.展开更多

At the same time, we should also see that the administration according to law is not perfect, and its shortcomings exist in different degree and need to be further improved. Based on the analysis of the status quo of grass-roots administrative law enforcement in China, this paper tries to put forward corresponding countermeasures, so as to promote the work of law-based administration for the corresponding study.展开更多

Over the past decades, China has scoredoutstanding achievements in implementing the two laws. In order to strengthen supervision of the implementationof the two laws and better protect the lawful rights and interests of the under-aged, the National People's CongressStanding Committee set up a Law Enforcement Check Group in July 2003, which carried out a nationwidecheck of the implementation of the two laws. On August 25, NPC Vice-Chairperson Gu Xiulian reported on theresult of the check to the fourth meeting of the Tenth NPC standing committee. She described the generalsituation in the implementation of the two laws as 'good' and also identified some problems and put forwardsome recommendations with regard to the enforcement and implementation of the two laws.The following are the excerpts of the report:展开更多
