A questionnaire survey of 100 police officers in the Nigeria Police Force was conducted. Almost three‐fourths (72%) of the officers indicated that they felt they had been discriminated against based upon their tribal membership. Tribal influence was thus considered by these officers to be pervasive within the Nigeria Police Force. More specifically, tribal influence was thought to play an especially important role in hiring practices, post assignments, disciplinary actions, transfers, and promotions.  相似文献

If psychological evaluations of criminal defendants could be performed in the community on an outpatient basis rather than in a distant state hospital on an inpatient basis, substantial savings could result and defendants' rights to speedy trial, bail, and the least restrictive alternative would more likely be respected. The authors thus developed a protocol, the mental state at the time of the offense screening evaluation (MSE), designed to enable outpatient evaluatiors to “screen out,” in the course of a brief interview, those defendants whose alleged criminal conduct clearly was not caused by “significant mental abnormality.” They tested the validity of the MSE by having pairs of mental health professionals use the MSE to evaluate 36 criminal defendants. The professionals' conclusions were then compared with the conclusions of state hospital professionals who performed a comprehensive evaluation of each defendant. They were also compared to court adjudications of the defendant's criminal charges. They found that the MSE screened out a large proportion of defendants (sufficient to suggest an improvement in cost-efficiency) without prejudice to those defendants who might have a valid legal defense.  相似文献

Public policing in England and Wales is currently undergoing and will undergo substantial changes to the way it delivers its services in the future. Consideration of the different proposals for change when viewed in isolation appears to produce uncertainty in terms of organisational structure. However, when considered as interdependent they provide a more clear and problematic issue that could undermine the current democratic model of policing utilised in this country. This article considers the ideas of the function of the public police within a democratic policing model and how changes such as the introduction of Police and Crime Commissioners, an apparent lack of engagement by the public with the democratic process, as well as the possibility of privatisation and outsourcing currently in vogue, may have a detrimental effect upon the policing philosophy that has underpinned policing in England and Wales for nearly 200 years.  相似文献

Research has shown that intimate partner violence (IPV) prevalence and severity is higher and IPV duration is longer among couples that have children. Women frequently report that their children are the reason why they stay, leave, or return to an IPV relationship. Our study used results from a two-wave telephone survey to determine what IPV-associated factors were significant predictors of respondents’ children witnessing IPV, as well as estimating prevalence of children’s exposure to violence. We found that an increase in respondents’ age was significantly associated with increased odds of a child being exposed to violence. We also found that children witnessing violence were almost twice as likely to have mothers who reported leaving abusers. We hypothesize that increasing age corresponds to improved confidence in help-seeking behaviors. Our findings represent an important first step for future research on understanding how children influence IPV victims’ decision-making in seeking out service providers for help.  相似文献

Many forensic document examiners are hesitant to express authorship opinions on photocopied handwriting as the photocopying process results in less feature information than original writing. This study aimed to test the accuracy of 15 examiners' opinions regarding whether photocopied questioned signatures were genuine or simulated. Each examiner received the same set of original signature exemplars, from one individual, and a set of eighty questioned photocopied signatures comprising of genuine and simulated signatures. The overall misleading (error) rate for the grouped examiners' opinions was 0.9% providing strong evidence that examiners can make accurate observations regarding the authorship of non-original handwriting.  相似文献

The Periodic Mobile Forensics (PMF) system investigates user behavior on mobile devices. It applies forensic techniques to an enterprise mobile infrastructure, utilizing an on‐device agent named TractorBeam. The agent collects changed storage locations for later acquisition, reconstruction, and analysis. TractorBeam provides its data to an enterprise infrastructure that consists of a cloud‐based queuing service, relational database, and analytical framework for running forensic processes. During a 3‐month experiment with Purdue University, TractorBeam was utilized in a simulated operational setting across 34 users to evaluate techniques to identify masquerading users (i.e., users other than the intended device user). The research team surmises that all masqueraders are undesirable to an enterprise, even when a masquerader lacks malicious intent. The PMF system reconstructed 821 forensic images, extracted one million audit events, and accurately detected masqueraders. Evaluation revealed that developed methods reduced storage requirements 50‐fold. This paper describes the PMF architecture, performance of TractorBeam throughout the protocol, and results of the masquerading user analysis.  相似文献

The aims of this study were to determine if computer‐measured dynamic features (duration, size, velocity, jerk, and pen pressure) differ between genuine and simulated signatures. Sixty subjects (3 equal groups of 3 signature styles) each provided 10 naturally written (genuine) signatures. Each of these subjects then provided 15 simulations of each of three model signatures. The genuine (N = 600) and simulated (N = 2700) signatures were collected using a digitizing tablet. MovAlyzeR® software was used to estimate kinematic parameters for each pen stroke. Stroke duration, velocity, and pen pressure were found to discriminate between genuine and simulated signatures regardless of the simulator's own style of signature or the style of signature being simulated. However, there was a significant interaction between style and condition for size and jerk (a measure of smoothness). The results of this study, based on quantitative analysis and dynamic handwriting features, indicate that the style of the simulator's own signature and the style of signature being simulated can impact the characteristics of handwriting movements for simulations. Writer style characteristics might therefore need to be taken into consideration as potentially significant when evaluating signature features with a view to forming opinions regarding authenticity.  相似文献

This article provides principal research in identifying and describing the nature and scope of current legal concerns within common interest communities (CICs) in the Commonwealth of Virginia. Very little federal guidance is available and Virginia statutes provide minimal direction in assessing the role of the many stakeholders in these “quasi‐public” governing entities. Of paramount concern is determining the degree to which legal mechanisms should mandate liability at the risk of dissuading voluntary participation in associations and also determining with whom the rights and responsibilities of CIC activity should reside—‐with the individual property owners, the majority of homeowners in the community as represented by a board, some governmental entity, or some combination of interested parties. This study, therefore, introduces the concerns of the Virginia courts and legislature, CIC attorneys, political scientists and management professionals as they grapple with finding a balance between preserving individual rights of property owners to self‐manage and at the same time, ensuring collective responsibility and attention to the governing activities that demand public scrutiny. It concludes with their suggested remedies for securing an adequate balance resulting in a successful future for CICs in Virginia and across the country.  相似文献
