Criminological research over the last couple of decades has improved our understanding of cybercrimes. However, this body of research is regarded as still theoretically thin and not fully developed; more knowledge on the actors involved, their characteristics, and modus operandi is needed. Some publications recently suggested that organised crime is or might be involved in cybercrimes, which would have important policing implications, but evidence-based research on this point is still scarce and inconclusive. This article seeks to further this path of inquiry by providing a systematic analysis of 40 cases from The Netherlands, Germany, UK, and USA where criminal networks were involved in financial cybercrimes affecting the banking sector. It also assesses whether and to what extent these criminal networks meet the definitions of organised crime and discusses the theoretical and policing implications of our findings.  相似文献

Objectives

Examines the influence of positive, negative, and neutral police behavior during traffic stops on citizen perceptions of police.

Methods

Participants were randomly assigned to view a video clip of a simulated traffic stop in which the officer communicates with the driver in a positive (procedurally just), negative (procedurally unjust), or neutral manner. After viewing the video, participants completed a survey about their perceptions of police, including their level of trust in police, obligation to obey police orders, and willingness to cooperate with police.

Results

Observing positive interactions with police enhanced people’s self-reported willingness to cooperate with police, obligation to obey police and the law, and trust and confidence in police, whereas observing negative interactions undermined these outcomes. The effects of these interactions were much stronger for encounter-specific outcomes than for more general outcomes.

Conclusions

The results from this randomized experiment confirm that procedural justice can enhance people’s prosocial attitudes toward police, whereas procedural injustice can undermine these attitudes. While positive (procedurally just) interactions tend to have weaker effects than negative (procedurally unjust) interactions, this study finds little support for the notion that only negative experiences shape people’s views about the police.

The need for mental health care has been steadily increasing for youth coming into contact with the juvenile probation system. This paper presents the results of a statewide survey of juvenile probation departments and associated mental health, health care, court, and education personnel in California. The intent of the survey was to better understand the costs and associated contexts of caring for youth with suspected mental disorders in juvenile detention facilities. The burden of caring for these youth on detention facilities and their staffs is substantial. Implications for courts, policy planning, training, and further research are discussed.  相似文献

The climate of school classrooms, shaped by a combination of teacher practices and peer processes, is an important determinant for children's psychosocial functioning and is a primary factor affecting bullying and victimization. Given that there are relatively few theoretically-grounded and validated assessment tools designed to measure the social climate of classrooms, our research team developed an observation tool through participatory action research (PAR). This article details how the assessment tool was designed and preliminarily validated in 18 third-, fourth-, and fifth-grade classrooms in a large urban public school district. The goals of this study are to illustrate the feasibility of a PAR paradigm in measurement development, ascertain the psychometric properties of the assessment tool, and determine associations with different indices of classroom levels of relational and physical aggression.  相似文献

We present a formal model of an intelligence agency that must divide its resources between the collection and analysis of information pertaining to terror plots. The model highlights the negative consequences of queues which form when collection exceeds analytic capacity. We incorporate the response of a terrorist organization to the operating characteristics of the intelligence system it faces, and solve for equilibrium strategies for the intelligence system and terrorist organization. Our results demonstrate the importance of properly balancing resources between collection and analysis, and stand in contrast to the observed state of overcollection in US intelligence agencies.  相似文献

The analysis of motor oils has wide applications in the forensic science field from comparing lubricants transferred between an automobile and a victim or crime scene to differentiating the compositions of plastic explosives. In this study, 40 unused motor oils were analyzed and compared by high-temperature gas chromatography-mass spectrometry to determine the potential for oil individualization. Oil samples were also collected from the crankcase dipsticks of 30 cars. Twenty-six of these oils could be differentiated from each other based on visual comparisons of the unresolved envelope (baseline rise due to incomplete separation) and the resolved hydrocarbons in the raw total ion chromatograms (TICs) and smoothed TIC data. Four of these oils were analyzed as unknowns and were correctly related to the corresponding vehicle. The use of extracted ion profiles (EIPs) was explored as a means to further discriminate between the indistinct samples based on the polycyclic aromatic hydrocarbon (PAH) content. The research discussed in this paper demonstrated that differentiation of motor oils was possible by examining the TIC, smoothed TIC, and EIP data.  相似文献

Although traditional intensive supervision programs that have aimed at increasing control and surveillance in the community have not been shown to reduce recidivism, prior research indicates that intensive supervision programs that are based on a human service philosophy and provide treatment to offenders offer more promise. The current research examined the effectiveness of fifty-eight intensive supervision programs and sought to determine whether program philosophy and treatment integrity are associated with reductions in recidivism. The results indicated that both program philosophy and treatment integrity vary independently of one another and are related to the ability of programs to produce meaningful effects on recidivism.  相似文献

There is a general acceptance that cellular material will transfer from one person to another person's fingernails through everyday contact. However, the level or degree of contact required to transfer sufficient cellular material in order to obtain a DNA profile is not known. This study examined swabs from the fingernails of 40 volunteers and compared the DNA profiles obtained to the daily activities of that individual. The majority (78%) of high level profiles obtained were associated with recent intimate contact. However, high level profiles were also obtained from the fingernails of individuals who shared accommodation with their partner, flatmates and/or children. Low level profiles and single profiles were associated with all levels of contact.  相似文献

This paper describes the economic conditions of urban and rural poverty in China. The examination of this problem deconstructs into three components and this explains why this problem is China's premier economic problem, despite its recent economic progress into a world ranked industrial economic power. Here, this paper examines the period of 1985 to 2008, a period of almost exponential growth. Even though during this period millions escaped from poverty levels of income, this was only part of the positive results. There were social negatives as well, and the main one was that economic inequality became worse, as the impoverished, as well as being affected by the current financial situation that has overcome the Chinese labor market, has put them into competition with the better off who are in the same economic predicament. As China merges into forms of economic globalization, any external blow will cause sharp fluctuations within the Chinese economy, as reflected within the labor market. Unemployment imposes direct impacts on incomes, and may give rise to social instability. As a result, job growth should be at the top of the macro-control agenda.  相似文献
