The Economic Analysis of Crime Behavior—Deduction of the Game Model between the Law-Man and the Offender  [PDF]
Shanshan Pan
American Journal of Industrial and Business Management (AJIBM) , 2016, DOI: 10.4236/ajibm.2016.67076
Abstract: George Tsebelis (1989) first uses the game model to analyze the behavior of police and public, but he has been questioned by many scholars in the related research. George’ conclusion and the scholars’ opinions are based on the premise that no pure strategy Nash equilibrium exists in the game. In fact, pure strategy Nash equilibrium exists in certain conditions, and it is necessary to study it because of the stabilization. In this paper, we research on the interaction of the law-man and the offender, and study how the law-man type and the conviction rate influence the behavior of the game participants. This paper also tests the conclusion of George, in the 1V1 game with the 100% conviction rate, the conclusion is correct that the increase of punishment can’t reduce the crime. This paper further discusses the law enforcement range that the law-man can be competent, and how the law-man type, law enforcement costs and the number of law-men impact the law enforcement range.
Panning for Long Noncoding RNAs
Shanshan Zhu,Xiao-Ou Zhang,Li Yang
Biomolecules , 2013, DOI: 10.3390/biom3010226
Abstract: The recent advent of high-throughput approaches has revealed widespread transcription of the human genome, leading to a new appreciation of transcription regulation, especially from noncoding regions. Distinct from most coding and small noncoding RNAs, long noncoding RNAs (lncRNAs) are generally expressed at low levels, are less conserved and lack protein-coding capacity. These intrinsic features of lncRNAs have not only hampered their full annotation in the past several years, but have also generated controversy concerning whether many or most of these lncRNAs are simply the result of transcriptional noise. Here, we assess these intrinsic features that have challenged lncRNA discovery and further summarize recent progress in lncRNA discovery with integrated methodologies, from which new lessons and insights can be derived to achieve better characterization of lncRNA expression regulation. Full annotation of lncRNA repertoires and the implications of such annotation will provide a fundamental basis for comprehensive understanding of pervasive functions of lncRNAs in biological regulation.
A Novel Attack Graph Posterior Inference Model Based on Bayesian Network  [PDF]
Shaojun Zhang, Shanshan Song
Journal of Information Security (JIS) , 2011, DOI: 10.4236/jis.2011.21002
Abstract: Network attack graphs are originally used to evaluate what the worst security state is when a concerned net-work is under attack. Combined with intrusion evidence such like IDS alerts, attack graphs can be further used to perform security state posterior inference (i.e. inference based on observation experience). In this area, Bayesian network is an ideal mathematic tool, however it can not be directly applied for the following three reasons: 1) in a network attack graph, there may exist directed cycles which are never permitted in a Bayesian network, 2) there may exist temporal partial ordering relations among intrusion evidence that can-not be easily modeled in a Bayesian network, and 3) just one Bayesian network cannot be used to infer both the current and the future security state of a network. In this work, we improve an approximate Bayesian posterior inference algorithm–the likelihood-weighting algorithm to resolve the above obstacles. We give out all the pseudocodes of the algorithm and use several examples to demonstrate its benefit. Based on this, we further propose a network security assessment and enhancement method along with a small network scenario to exemplify its usage.
The Influences of WTO Accession on China’s State-Owned Enterprises  [PDF]
Shanshan Li, Ningxiang Xu
Open Journal of Business and Management (OJBM) , 2015, DOI: 10.4236/ojbm.2015.32019
Abstract: Up to the present, nearly fourteen years have passed since China’s accession to WTO. Among the various impacts the accession may bring about, the one on State-owned Enterprises (SOEs) was most widely concerned due to their special characteristics and particular roles in Chinese economy, politics and society. This essay will briefly introduce the history of China’s SOE reforms and then summarize previous research to demonstrate the expected influences of the accession. Then privatization and removal of protective government policies will be examined in detail, followed by an evaluation of the effect of privatization.
The Relationship between China’s Population Structure Change in Minority Areas, Economic Growth and Demographic Dividend—Based on an Empirical Analysis of Time Series Data from 1992 to 2012  [PDF]
Shanshan Gao, Junlin Shao
Open Journal of Business and Management (OJBM) , 2016, DOI: 10.4236/ojbm.2016.42028
Abstract: Because the sustainability of the economic development model has drawn much attention recently, the academic circle and the government have begun to focus on the population of minority areas. In past literature, due to the lack of the positive analysis of the relationship between minority population transition and economic development, and due to sample limitation and other factors, the research result is not very convincing. This paper used the economic convergence theory to establish a theoretical model, and selected the panel data in eight minority-concentrated provinces from 1992 to 2012 to analyze the impact of population transition in these provinces on economic growth. The result reveals a significant positive correlation between investment, human capital, the growth rate of labor and per capita GDP growth, a significant negative correlation between children’s dependency ratio and per capita GDP growth, and an uncertain relationship between elderly dependency ratio and per capita GDP growth. To maximize the democratic dividend, it is necessary to speed up the development of educational undertakings in minority areas, and to accelerate the industrial structure transition of minority areas. It is also important to perfect institutional improvement of minority areas.
Research on Planning and Management of Urban Parking Lot—Taking Hangzhou as an Example  [PDF]
Shanshan Yang, Lixia Huang
Current Urban Studies (CUS) , 2017, DOI: 10.4236/cus.2017.54021
With the increasing number of city cars, traffic jams and parking difficulties have become a bottleneck of urban development. Creating the conditions to achieve the dynamic balance between road and automobile resources and allocate the parking resources reasonably is not only beneficial to the rapid development of cities, but also convenient for people to travel by bus or car. It can also ensure orderly parking, implementation of normative management, which can solve the problem of traffic jam and parking difficulties thoroughly. This paper takes the city of Hangzhou as an example, discussing the existing problems and countermeasures in urban parking planning and management. This paper first analyzes the existing problems in Hangzhou parking management from aspects, such as the serious shortage of parking lots, the lack of a clear management body, the inefficient use of car parks in some areas and lack of a long-term mechanism to attract social forces to participate in car park construction, and then proposes solutions to the problems from different aspects, such as giving full play to the pilot role of urban parking planning and management, establishing and improving the mechanism on parking lot management, and introduces social forces to participate in the construction and management of car parks, which provides reference for the planning and management of urban parking lot in China.
Study on the Sustainable Development of Targeted Poverty Alleviation through Financial Support  [PDF]
Lixia Huang, Shanshan Yang
Current Urban Studies (CUS) , 2018, DOI: 10.4236/cus.2018.61009
The 13th five-year plan proposed that rural poor people in China’s current standards will lift out of poverty by 2020, and all the poor counties were lifted out of poverty, addressing regional overall poverty. Since then, China’s poverty alleviation work has been fought in an all-round way. Targeted poverty alleviation is the mode of poverty alleviation that applies scientific and effective procedures to implement precise identification, accurate help, and precise management, aiming at different poverty-stricken farmers and different poverty- stricken areas. Firstly, this paper studies the problems that are prevalent in the process of promoting financial support for targeted poverty alleviation in China, takes Hebei province as an example to analyze the current situation of financial precision poverty alleviation, proposes to vigorously develop inclusive finance in poor areas, and advocates that financial institutions work closely with government departments to improve the effectiveness of anti- poverty work and establish and improve the risk diversification compensation mechanism to promote the sustainable development of financial poverty, as a result to effectively promote the process of targeted poverty alleviation and to achieve the goal of building a moderately prosperous society in all respects by 2020.

Tang, Xiaobo;Zhang, Rong;Wang, Zhigang;Yu, Lei;Li, Shanshan;Zhu, Daling;
Brazilian Archives of Biology and Technology , 2008, DOI: 10.1590/S1516-89132008000200007
Abstract: extracellular ca2+ influx was blocked by l-type ca2+ channel blocker nifedipine to observe the effects of 15-hydroxyeicosatetraenoic acid on the constriction of rabbit pulmonary artery rings and on the changes of ca2+ level in the rabbit pulmonary artery smooth muscle cells, and further to investigate the mechanism of the calcium mobilization induced by the 15-hete under hypoxic conditions. the effect of extracellular ca2+ on tension of the rabbit pa rings was also studied. nifedipine (10 μ mol/l) had no effect on 1 μ mol/l 15-hydroxyeicosatetraenoic acid induced vasoconstriction under normoxic and hypoxic conditions. intracellular ca2+ increased markedly in the 15-hete group (cells were exposed to 1 μ mol/l 15-hete for 8 min during culture) compared to the control group (p < 0.05). the study demonstrated that the 15-hete could induce the elevation of ca2+ in the pulmonary artery smooth muscle cells and the elevated calcium came from the release of the intracellular calcium.

Abstract: Rad51/RadA paralogs found in eukaryotes and euryarchaea play important roles during recombination and repair, and mutations in one of the human Rad51 paralogs, Rad51C, are associated with breast and ovarian cancers. The hyperthermophilic crenarchaeon Sulfolobus tokodaii encodes four putative RadA paralogs and studies on these proteins may assist in understanding the functions of human Rad51 paralogs. Here, we report the biochemical characterization of stRadC2, a S. tokodaii RadA paralog. Pull-down assays revealed that the protein was able to interact with the recombinase, RadA, and the Holliday junction endonuclease, Hjc. stRadC2 inhibited the strand exchange activity of RadA and facilitated Hjc-mediated Holliday junction DNA cleavage in vitro. RT-PCR analysis revealed that stRadC2 transcription was immediately reduced after UV irradiation, but was restored to normal levels at the late stages of DNA repair. Our results suggest that stRadC2 may act as an antirecombination factor in DNA recombinational repair in S. tokodaii.
