Citizen co‐production of cyber security: Self‐help,vigilantes, and cybercrime

Given the limited resources and capabilities of states to maintain cyber security, a variety of co‐production efforts have been made by individuals or by collectives, of varying degrees of organization and coordination. This article identifies different forms of citizen co‐production of cyber security and notes the risk of unintended consequences. Safeguards and principles are proposed in order to facilitate constructive citizen/netizen co‐production of cyber security. Although co‐production of security can contribute to social control, only those activities within the bounds of the law should be encouraged. Activities of private citizens/netizens that test the limits of legality should be closely circumscribed.     

从人性完满实现看和谐社会的构建

和谐社会是一个以人为本的社会,以人的全面自由发展为目标。而人的全面发展也即人性的完满实现。科学对人性完满实现的作用是有其限度的。吸收宗教的合理成分有助于人性的完满实现。“构建社会主义和谐社会”的提出体现了向一种神圣与世俗相结合的新价值观的转换。     

经济引力原理引论

人类社会进入工业化和城市化的阶段后,经济发展的不平衡规律表现得更加明显,这种不平衡规律不仅在国与国之间体现出来,而且在一国内部也表现得非常突出。一国内部的不平衡发展是什么因素决定的?有什么规律和特点?有否调节的手段和办法?政府在其中起着什么样的作用?大量的资料分析表明,区域之间经济发展过程中存在着经济引力原理,因此,需要对经济引力的形成、构成要素、特点和我国经济引力区的划分类型、区域引力的调节等进行探讨和论述。     

当代中国马克思主义大众化进程中存在的主要问题

马克思主义是引领我们兴党、富国、强民的科学理论。推动当代中国克思主义大众化,不仅仅是一种理论诉求,也是一种现实需要,更是一种历史使命。但是,由于宣传主体、理论宣传等方面存在的问题,影响和制约了当代中国克思主义大众化的进程。只有通过对这些问题的分析,才能为推动当代中国马克思主义大众化的实现提供新的思考。     

Determining Shoe Length from Partial Shoeprints

The length of a shoe has significant value in reflecting characteristics of the owner, and thereby, it can help in tracking suspects in criminal cases. However, the shoeprints left at a crime scene are often incomplete, resulting in difficulties in assessing shoe length. To find a way to estimate the shoe length from a partial shoeprint, 109 shoes with different sizes and general patterns were collected, and their prints were lifted using magnetic powder. Four feature points were defined on a shoeprint, and the longest distance between the feature points was defined as shoe length. Using linear, quadratic, and cubic regression analyses, a total of 15 equations were obtained between the shoe length and the other distances between the feature points. Out of these, the five most accurate equations were selected as the optimal equation. The verified test, including another 18 pairs of shoes, showed an average error of equations between 0.591 cm and 0.732 cm. The equations were also applied in two practical cases, resulting in good accuracy. The study demonstrates that shoe length could be determined from partial shoeprints through the proven equations.     

从《论干部政策》看陈云的“用人之道”

“政治路线确定之后,干部就是决定的因素。”[1]中国共产党在革命、建设和改革的过程中,一贯重视干部的作用。陈云作为党和国家的重要领导人,他对干部政策问题更是高度关注,提出了一系列关于干部政策的真知灼见和思想理论,形成了自己独有的“用人之道”。《论干部政策》是陈云“用人之道”的重要体现。在文中,陈云以“了解人”“气量大”“用得好”“爱护人”为切入点,分别从这四个维度生动清晰地阐明了“用人”的基本前提、关键所在、核心要义和本质要求,为我们系统地诠释了自己的“用人之道”。     

Population drug use in Australia: a wastewater analysis

Accurate information on drug use in communities is essential if health, social and economic harms associated with illicit drug use are to be addressed efficiently. In most countries population drug use is estimated indirectly via surveys, medical presentations and police and custom seizures. All of these methods have at least some problems due to bias, small samples and/or long time delays between collecting the information and analysing the results. Recently the direct quantification of drug residues in wastewater has shown promise as a means of monitoring drug use in defined geographical areas. In this study we measured 3,4-methylenedioxymethamphetamine (MDMA), methamphetamine and benzoylecgonine in sewage inflows in metropolitan and regional areas of Australia and compared these data with published European data. Cocaine use was small compared to European cities (p<0.001) but was compensated for by much greater consumption of methamphetamine (p<0.001) and MDMA (p<0.05). MDMA was more popular in regional areas (p<0.05) whereas methamphetamine and cocaine were mainly consumed in the city (p<0.05). Greater than 5-fold increases in MDMA use were detected on weekends (p<0.001). This approach has the potential to improve our understanding of drug use in populations and should be further developed to improve prevention and treatment programs.
