It has become a controversial sea area due to the loopholes in the modern law of the sea. It is competed by neighboring countries for its interests, which exacerbate the tense situation in China＇s enforcement of maritime rights protection and poses the serious threat to our country＇s sovereignty over the South China Sea. The article takes the South China Sea controversial maritime rights enforcement model as the starting point. It contrasts the status quo of maritime rights enforcement system both at home and abroad, and analyzes the existing laws and regulations of maritime rights protection system in our country, such as the imperfect laws and regulations, the unreasonable establishment of law enforcement agencies and the imperfect law enforcement system. It also puts forward the strategy and idea of perfecting the law enforcement system of maritime rights protection in our country, which is of far-reaching significance to the strategy of safeguarding the maritime rights and interests of China and building a maritime power.展开更多

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

It consists of a Wi-Fi infrastructure that enables communication between moving vehicles and a central node. Unlike existing solutions, which address single violations, the proposed model encompasses several issues like exceeding speed limits, entering a no entry street, car theft, congestion and tolling. OPNET simulations were run to test the Wi-Fi model and define its different characteristics and limitations. A proof-of-concept case was modeled, and the proposed architecture succeeded in meeting all design requirements.展开更多

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
