No full textAbstract
Along with the bursting hostility between two sides of the strait yet of the mutual exchanges, still with the commencement of China's reformation and opening up, the injection of world capital and the large-scale westward aiming of Taiwanese businessmen, China's economy has been keeping growing and expending, and technology and communications have also been well developed, accompanied by the emergence of Unheard of telecommunications fraud, Internet telecommunications fraud has developed from a relatively small scale of groups to a large-scale multinational organization in one deadly diving under the development for more than a decade. The problems of trust, coordination, as well as stability between societies directly cause huge financial losses and mental detriment to people, which may even lead to casualties at some circumstances.
Such felony has continued to spread to Southeast Asia, Africa, Eastern and Southern Europe and other regions in recent years. As for how to unite synchronized cooperative law enforcement actions in third places, increase mutual trust, expand the content of investigation cooperation, and the applicability of investigation content, etc., the law enforcement between countries seems quite difficult, but the ownership of the criminal jurisdiction of the defrauding members and the destination of the suspect's repatriation have become disputes before the judicial authorities of both sides of the strait. However, fraud groups are now taking malicious advantages of the advancement of science and technology. Besides, their criminal methods are bettering gradually, and the tools for committing crimes are diverse. They are good at using various telecommunication network technologies, collecting head accounts and cross-border operations of criminal groups to evade criminal persecution. The analysis of group case cooperation has nowadays become the focus of researches concerned.
The research collects and sorts out a large number of "Agreement on Cross-Strait Joint Crime Prevention and Mutual Legal Assistance", aiming at the problems existing in cross-Strait mutual judicial assistance after the signing of the agreement, the current situation and dilemma of cross-strait cooperation, and the basic cases of cross-Strait police cooperation on international police law enforcement carry out relevant analysis and discussion, then to fix out the above-said problems, proposing relevant solutions and cooperation. Last but not least, fraud criminal prevention and defense promotion are the main incentives of the research

Reason: Author requested U of Illinois access only (OA after 2yrs) in Vireo ETD systemU of I Only Restriction Lifted for Item 89434 on 2017-09-30T09:15:38Z.I reviewed the recently developed limited-information model fit statistics by Maydeu-Olivares and colleagues (e.g., Maydeu-Olivares & Joe, 2005; Maydeu-Olivares & Liu, 2012; Liu & Maydeu-Olivares, 2014) and conducted a simulation study to explore the properties of these new statistics under conditions often seen in practice. The results showed that the overall and piecewise fit statistics were to some extent sensitive to misfit caused by multidimensionality, although the limited-information fit statistics tended to flag more item pairs as misfit than the heuristic fit statistics. I also applied the fit statistics to three AP® exams, one personality inventory, and a rating scale used in organizational settings. Although a unidimensional IRT model was expected to fit the Physics B Exam better than the English Literature Exam, the average piecewise fit statistics showed no such difference. The fit statistics also suggested that a more advanced IRT model should be fitted to the self-rated personality inventory. Finally, the fit statistics seemed to be effective in detecting misfit caused by data skewness.Submission published under a 24 month embargo labeled 'U of I only', the embargo will last until 2017-08-01The student, Liwen Liu, accepted the attached license on 2015-06-30 at 20:12.The student, Liwen Liu, submitted this Dissertation for approval on 2015-06-30 at 20:24.This Dissertation was approved for publication on 2015-07-01 at 10:13

In-situ laser synthesis of ZIF-67@ZIF-8-derived CoZn@NC/graphene as a flexible electrode for electrochemical metol detection
No full textBackground: Designing a sensitive and selective electrochemical sensor to determine metol (MT), a toxic phenolic substance, has a great significance. The development of new and advanced materials with excellent electrocatalytic properties has been receiving more attention in the field of electrochemical sensor. Metal-organic frameworks (MOFs) derived bimetallic transition metal alloy/carbon composites are regarded as outstanding electron-conductive transport media. However, their preparation always requires a high-temperature and hours of calcination treatment. Consequently, it is vital to advance a user-friendly, straightforward and scalable method to construct MOF derived metal/carbon materials. Results: Herein, we developed a two-step laser irradiation process. The first-step laser irradiation made the production of laser-induced graphene (LIG) on a flexible polyimide (PI) film. The second-step laser irradiation transformed a ZIF-67@ZIF-8/LIG into a LIG supported a core-shell structure of CoZn alloy nanoparticle encapsulated in N-doped carbon (CoZn@NC), named as CoZn@NC/LIG. Then, the enhanced electrochemical sensing ability of CoZn@NC/LIG electrode was studied for the detection of MT. The fabricated sensor owned a range of linear quantification of 0.01-10 mu M for MT sensing with a low limit of detection (LOD) of 1.48 nM. Moreover, the developed flexible LIG working electrode offered respectable selectivity, acceptable flexibility and high stability. It was then applied to detect MT in actual water samples with exceptional recovery rates, confirming its reliability in complex sample matrices. Significance: Gaining advantages from the combined effects of high electrocatalytic activity of the multilevel CoZn@NC active sites and excellent electroconductibility of 3D hierarchical porous structure of LIG, the established CoZn@NC/LIG flexible electrode achieved highly-sensitive determination of MT. The discoveries of this research present a novel and efficient methodology for designing MOF-derived metal/carbon composites and flexible electrode with excellent performance in environmental analysis.This work was financially supported by the Hubei Provincial Department of Education Science and Technology Plan Project (Grant Nos.

Incorporation of laser-induced graphene with hierarchical NiCo layered double hydroxide nanosheets for electrochemical determination of glucose in food and serum
No full textDependable and sensitive glucose (Glu) testing in foodstuff and blood serum is highly desirable to prevent and treat diabetes. Electrochemical quantification of Glu has attracted great interests due to the advantages, including simple operation, higher sensitivity, easy miniaturization, ease of on-site and wearable detection as well as fast response. High costs and environmental dependence of enzymes pose a challenge to the electrochemical enzymatic biosensors. Nonenzymatic electrochemical Glu sensors are urgently needed to aid the Glu detection in human serum and food samples. To fabricate flexible Glu electrochemical sensors, designing suitable electrode substrate and efficient electrocatalyst is of paramount significance. Herein, the porous patterned laser-induced graphene (LIG) was fabricated on polyimide substrates through an efficient laser-inducing technology, and then used directly as the electrode substrate. Electrochemical deposition of NiCo layered double hydroxide (LDH) nanoflakes on the LIG surface was then conducted to achieve NiCo-LDH/LIG electrode as a Glu sensor. Under optimal conditions, this sensor displays a low detection limit of 0.05 mu M. Two sets of broad detection linear ranges were found to be from 0.5 to 270 mu M and from 0.27 to 3.6 mM, with high sensitivities of 9.750 mu A mu M-1 cm(-2) and 3.760 mu A mu M-1 cm(-2), respectively. The enhanced performance was ascribed to the cooperative action of NiCo-LDH and LIG, in which porous LIG provides extraordinary electroconductibility and a high surface area, while NiCo-LDH offers numerous exposed active sites and outstanding electrocatalytic performance. Practical application was further verified during the Glu detection in human serum and food samples. This research confirms that the NiCo-LDH/LIG composite is a prospective electrode for high-performance Glu sensor and provides a way of developing nonenzymatic electrochemical sensors to analyze the Glu in human serum and food samples, opening new avenues in electrochemical sensing.This work was financially supported by open project funding of Ministry of Education Key Laboratory for the Synthesis and Application of Organic Functional Molecules of Hubei University of China (No. KLSAOFM2302), the Natural Science Foundation of Hubei Province of China (No. 2021CFB1192) and the Graduate Innovative Fund of Wuhan Institute of Technology of China.
