Smart all-time vision:The battery-free video communication for urban administration and law enforcement

The Chinese government is dedicated to enhancing the level of informatization in administrative law enforcement to ensure fairness and increase credibility.Currently,law enforcement has exposed such problems as insufficient force,difficulties in collecting evidence,and low evidential power.These problems contradict the principles of rule of law and standardization.Many local governments have implemented advanced information technologies for urban administration and law enforcement,including big data,artificial intelligence,and IoT.Among these technologies,IoT is the core communication infrastructure for innovative law enforcement platforms.However,traditional video communications rely on batteries or dedicated power sources,leading to maintenance challenges and high power consumption.In this paper,we propose AT-Eye,a new video communication paradigm for all-time law enforcement video monitoring,which is battery-free and high-throughput.The key enabler of AT-Eye is ambient backscatter technology,which enables energy harvesting and video communication simultaneously.Unlike previous methods,our proposal introduces a novel CCK-based modulation for tag cameras and achieves 4-way concurrency.The modulation is simple because it uses phase difference and it is energyefficient because generating square waves is adequate.Moreover,to ensure full compatibility with COTS WiFi,we modulate the physical service data unit.Therefore,data recovery is possible using only commercial NICs.We conduct comprehensive experiments to examine our proposal and experiment results show that AT-Eye achieves a throughput of 10.8 Mbps with COTS radios.We also simulate a 16-way battery-free tag camera system,demonstrating AT-Eye’s feasibility of high-definition video communication.

Analysis of Economic Efficiency of Wildlife Law Enforcement in Serengeti Ecosystem Tanzania

Law enforcement remains to be the main strategy used to combat poaching and account for high budget share in protected area management. 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.

Relationship between the Three Laws of Dialectics of Nature and Agricultural Development

Based on the three laws of dialectics of nature-the law of unity of opposites, the law of mutual change of quality and the law of negation of negation, this paper analyzes the relationship between the three laws and agricultural development, and proposes making good use of the three laws to promote the better development of agriculture and realize agricultural modernization.

On the Choice of the Path for the Development of the Rule of Law in China: From the Perspective of Improving the Rule of Law Quality by Promoting the Substantive Rule of Law

The continuous debate on the formal rule of law and the substantive rule of law in the construction of the rule of law in China not only affects the understanding of the connotation of the rule of law in China,but also the choice of the path for the development of the rule of law in China.In the new stage of “comprehensively advancing the Law-Based Governance of China”,the process of “comprehensively advancing the Law-Based Governance of China” is also a process of continuously improving the rule of law quality in China.And from this perspective,the relationship between the formal rule of law and the substantive rule of law has got a new meaning.Promoting the substantive rule of law is an important way to realize the development of the rule of law and improve the quality of the rule of law.At the same time,the promotion of the substantive rule of law should follow the “people-centered” nature of the rule of law and the objective is conducive to the promotion of the rule of law and the formation of the “rule of law ecology”.

Study on Game Theory of Social Law Enforcement

Based on the basis of the two stage dynamic game of complete information and purely tactful perfect equilibrium theory, the non cooperative gaming between the police department and the criminals is analyzed. Dynamic game can be proved to forecast and explain potential tactful choices of the police department and the criminals at various stages, so as to analyze the essence of the law enforcement by the theoretical models.

Achievements Outstanding In Protecting Minors——Report on enforcement of Law on the Protection of Minors (excerpts)

The Law of the People's Republic of China on the Protection of Minors and the Law ofthe People's Republic of China on the Prevention of Juvenile Crimes were passed on September 4, 1991 and June 28,1999 and came into force on January 1, 1992 and November 1, 1999. 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:

Spatio-temporal Characteristics and Geographical Determinants of Air Quality in Cities at the Prefecture Level and Above in China

In recent years, the large scale and frequency of severe air pollution in China has become an important consideration in the construction of livable cities and the physical and mental health of urban residents. Based on the 2016-year urban air quality index(AQI) data published by the Ministry of Environmental Protection of China, this study analyzed the spatial and temporal characteristics of air quality and its influencing factors in 338 urban units nationwide. The analysis provides an effective scientific basis for formulating national air pollution control measures. Four key results are shown. 1) Generally, air quality in the 338 cities is poor, and the average annual values for urban AQI and air pollution in 2016 were 79.58% and 21.22%, respectively. 2) The air quality index presents seasonal changes, with winter > spring > autumn > summer and a u-shaped trend. 3) The spatial distribution of the urban air quality index shows clear north-south characteristic differences and a spatial agglomeration effect; the high value area of air pollution is mainly concentrated in the North China Plain and Xinjiang Uygur Autonomous Region. 4) An evaluation of the spatial econometric model shows that differences in urban air quality are due to social, economic, and natural factors.

Analysis of Laws and Regulations on Vaccine Quality Control in China

Objective To analyze laws, regulations and the responsibilities of relevant authorities for vaccine quality control and to provide suggestions for improving vaccine quality control system in China. Methods Laws and rules issued by related authorities were classified and studied. Results and Conclusion There are still some problems in the basic laws and regulations, including the lack of legal basis, the unclear responsibilities of relevant authorities and so on. We should improve the current laws, regulations as well as the responsibilities of the authorities so as to build up a sound system of vaccine traceability gradually.

Guideline for Making,Enforcement of Laws

Respect for and protection of human rights is a constitutional principle for China. China＇s Constitution states： ＂The ,State shall respect and protect human rights＂ In practice, this constitutional principle serves as an important guideline for the making and enforcement of laws.

Population Dynamics of Large Herbivores and the Framing of Wildlife Conservation in Zimbabwe

This article reviews: 1) The role of natural and human-induced controls in influencing large herbivore populations;2) how human controls (i.e., policy instruments, incentives and provisions) influence human activities and wildlife conservation;and 3) media framing of wildlife conservation using Zimbabwe as a case study, in particular Gonarezhou National Park and adjacent areas. The review shows that droughts are important in influencing large herbivore populations in semi-arid ecosystems;political instability and economic collapse does not necessarily lead to increased illegal hunting in situations where policy instruments, such as laws, are enforced. A higher perceived effectiveness of Communal Areas Management Programme for Indigenous Resources was partly associated with a decline in human-wildlife conflicts and there was a spill-over effect of frames from the political domain into wildlife conservation following Zimbabwe’s land reforms in 2000. It is concluded that natural bottom-up processes (e.g., droughts) influence large herbivore population dynamics whereas policy instruments, incentives, provisions and societal frames mainly have a top-down effect on wild large herbivore populations in savanna ecosystems.

Scalable and Accessible Crash Hot Spot Detection for Traffic Law Enforcement

Law enforcement agencies have begun utilizing traffic and crash data to improve traffic law enforcement delivery. 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 a range of customizable parameters based on location, date and time, and 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 crash density and then ranks each hot spot using a standardized z-score 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.

Does Environmental Laws and Policies Work?A Review Of Ghana’s Case

Enforcing environmental laws and policies has been one of the pressing agenda globally.Despite the mandate given to the Environmental Protection Agency(EPA)by the Act 490,there are still numerous environmental issues unaddressed in Ghana.This paper is geared towards unravelling and identifying the current additions that have been made to existing literature on environmental laws and policies in Ghana.This paper made a wide-ranging general literature review to outline significant contributions concerning environmental laws and policies.Numerous environmental laws and policies were identified but have been fragmented and are not codified in a particular document.It is evident from the review of literature existing that there are still areas for advanced research on the topic of environmental laws and policies placing more emphasis on institution concerned with environmental issues at global level.The study recommended the need for capacity building for environmental personnel and data due to the numerous technological advancement to better assist the implementation and enforcement of environmental laws in Ghana.

Impact of Institutional Quality on Multilateral Aid in Nigeria

The linkage between quality of institutions and economic performance of nations has generated a lot of interest among scholars,due to their influence on development of many countries and effective use of resources including foreign aid from multilateral organizations.Two strands of theories emerge on the institutions-multilateral aids nexus:those for benefits of aid to growth and development;and those for harms caused by aid.The research objective is to investigate the impact of institutional quality on multilateral aid in Nigeria.To do this,the study applied auto-regressive distributed lag(ARDL)bounds testing approach.Data for the study were sourced from the ICRG data,WGI data,QoG database,Transparency International,and World Development Indicators(WDI).The findings show that institutional quality variables do not have any influence on the multilateral aid in Nigeria,except the‘independence of judiciary’which appeared statistically significant.In the short-run analysis,the disequilibrium in the long-run equilibrium is corrected for in the next quarter period by about 25%;almost all the variables are statistically and significantly influencing multilateral aid.It is therefore recommended that donor agencies should consider other factors that negatively influence official development assistance(ODA)such as politics,location and colonial history.

综合行政执法改革过程中的多维结构变迁与能动者策略

推动执法权属地化与综合化是夯实基层政权建设的重要一环,但在政策实践中,并不必然带来治理效能的提升。事权下放后,基层治理结构的实质性变革如何形塑执法主体的行为策略,以提升事权承接的有效性,是亟待回答的重要议题。文章从“结构—过程—功能”的视角出发,对一个街道综合行政执法体制改革进行系统考察,构建理解多维结构变迁中能动者策略生成的分析框架。研究发现,在改革过程中,综合执法部门所嵌入的横向结构在权力、责任和资源维度发生系统性变迁。执法主体在基层治理结构所设定的规则约束与行动空间中,基于复杂性和概率性两个维度,划分四种类型的执法任务,并能动地创设动员式、裁剪式、扩容式等执法策略,衔接再配置的结构性要素与复杂外部事务治理环节,从而有效回应“块块”运作规则和事权下放的内在要求。

“Fundamental Rights and Private Law” in China

The Qi Yuling case is a crucial juncture in the study of “fundamental rights and private law” in China, yet relevant research is underpinned on two clues. The first is that the increasing interest in the “constitutionalization of private law” worldwide provides knowledge resources and reference materials for scholars in China;the second is the understanding and exploration of the judicial application of the Constitution since the 1980s. Among them, such concepts as “the Constitution has direct legal effect” and “the Constitution needs to be implemented by the people” could have directly affected the Qi Yuling case. Focusing on such topics as the case of Qi Yuling, judicial enforcement of the Constitution, and the compilation of the Civil Code, scholars discussed the ways and scope for inclu ding fundamental rights in private law based on their experience abroad. They also looked into specific issues, covering how fundamental rights affect civil acts and the private law effects fundamental rights like personality rights, equali ty rights, freedom of speech, and protection of personal information. In the context of promoting the full implementation of the Constitution in the new era, “fundamental rights and private law” is still a field with great potential in both practice and theory.
