Criminal network vulnerabilities and adaptations

The current paper aimed to investigate the effectiveness of five law enforcement interventions in disrupting and dismantling criminal networks. We tested three law enforcement interventions that targeted social capital in criminal networks (betweenness, degree and cut-set) and two interventions that targeted human capital (actors who possess money and those who possess precursor chemicals). These five interventions are compared with each other and with random (opportunistic) removal of actors in two settings: (i) with network adaptation incorporated into the simulations and (ii) without network adaptation. Results illustrate that the removal of actors based on betweenness centrality was the most efficient strategy, leading to network disruption in the least number of steps and was relatively consistent across replications. Targeting actors who possessed money was the second most effective overall and was also relatively consistent in its disruptive effect.     

Forensic Biomechanical Analysis of Falls from Height Using Numerical Human Body Models*

Abstract: This article describes the method of using human body models developed originally for the use in automotive safety in forensic reconstructions of falls from height. The MADYMO^® software package and multibody human body models were used in forensic analyses of two real cases—a fatal fall from a window c. 13.8 m above the ground and a fall into a c. 2.5‐m deep cellar pit resulting in isolated ankle joint injury. The performed series of numerical simulations helped to reconstruct the events and to resolve legally relevant questions concerning various aspects of the falls. The benefits as well as limitations and potential biases associated with the use of numerical simulation in forensic biomechanical settings are discussed. The method has proven to be effective under specific circumstances, though the cost (both financial and temporal) still prevents it from wider use.     

仿真分析取证模型的形式化研究

计算机犯罪的多样性使得现有的静态取证和动态取证模型均已不能很好的满足计算机取证的要求,亟需建立一种新型态的取证模型。仿真分析取证模型运用“自顶向下”的形式化建模方法,结合虚拟机技术的最新发展成果,通过虚拟犯罪现场重建构建了一种并行的取证平台,为侦查实践和司法实务提供了有力的技术支撑。     

试论警察射击心理素质的培养

警察射击心理素质训练直接关系到警务人员射击技术水平,是提高学员综合素质的重要环节。因此,必须克服目前教学工作中忽视心理素质作用的思想,纠正将警察实战射击心理训练等同于运动射击心理训练的做法,将心理素质训练摆到应有的位置。应在＂练为战＂的思想指导下,通过创设各种模拟实战心理训练情景,培养学生过硬的心理素质,并在不同的教学训练阶段采取相应的心理训练方法,使教学和实践有机相结合,培养高素质的公安大学生射击人才。     

The broadcast media: A persuasive institution

At present, the broadcast media (radio and television) because of their pervasive presence in society are a “taken‐for‐granted” part of the social environment, as natural as the air one breathes. The persuasive power of the media is not so readily ascertained by all who watch and listen. Looking at the growth and spread of the media in three highly industrialized countries, namely Japan, the United Kingdom, and the United States, each with its own particular broadcast system, one can see the variety of emphasis on commercial and public broadcasting. Since the media have more in common with interpersonal communication than they have differences, the public is constantly open to media messages, continuously processing as well as responding to information received via media sources. The persuasive effect of these broadcast media in terms of the latent function of commercial messages needs deep and careful analysis.     

Microwave Selective Thermal Development of Latent Fingerprints on Porous Surfaces: Potentialities of the Method and Preliminary Experimental Results

The thermal development of latent fingerprints on paper surfaces is a simple, safe, and chemicals‐free method, based on the faster heating of the substrate underlying the print residue. Microwave heating is proposed for the first time for the development of latent fingerprints on cellulose‐based substrate, in order to add to the thermal development mechanism the further characteristic of being able to heat the fingerprint residues to a different extent with respect to the substrate, due to the intrinsic difference in their dielectric properties. Numerical simulation was performed to confirm and highlight the selectivity of microwaves, and preliminary experimental results point out the great potentialities of this technique, which allowed developing both latent sebaceous‐rich and latent eccrine‐rich fingerprints on different porous surfaces, in less than 30 sec time with an applied output power of 500 W. Microwaves demonstrated more effectiveness in the development of eccrine‐rich residues, aged up to 12 weeks.     

New methods for examining expertise in burglars in natural and simulated environments: preliminary findings

Expertise literature in mainstream cognitive psychology is rarely applied to criminal behaviour. Yet, if closely scrutinised, examples of the characteristics of expertise can be identified in many studies examining the cognitive processes of offenders, especially regarding residential burglary. We evaluated two new methodologies that might improve our understanding of cognitive processing in offenders through empirically observing offending behaviour and decision-making in a free-responding environment. We tested hypotheses regarding expertise in burglars in a small, exploratory study observing the behaviour of ‘expert’ offenders (ex-burglars) and novices (students) in a real and in a simulated environment. Both samples undertook a mock burglary in a real house and in a simulated house on a computer. Both environments elicited notably different behaviours between the experts and the novices with experts demonstrating superior skill. This was seen in: more time spent in high value areas; fewer and more valuable items stolen; and more systematic routes taken around the environments. The findings are encouraging and provide support for the development of these observational methods to examine offender cognitive processing and behaviour.     

Changes of Legal Scenarios in the Era of Artificial Intelligence

The superposition of artificial intelligence (AI) and non-state power has aggravated changes in state functions, and has downgraded centralism of political state. The “Intelligent Leviathan” will persist in objectifying the “individual.” The relationship mode of “human-human” being transformed into the mode of “humantechnology-human, ” is giving rise to a new social structure, while state power together with non-state power, law and the algorithm, as well as ethics and technologies, are creating a new order. The major threat to freedoms and rights is horizontal non-state power, instead of vertical state power. Going through profound changes, legal scenarios need reconstruction of “kindness” dimension for balancing the “rights priority” theory, while the “obligations standard” should be recovered in the sense of legal technology to rectify the “rights standard” and to resolve the “rights disability.”
