A cross-national comparison of school drug policies in Washington State, United States, and Victoria, Australia

Using mail survey data collected from primary and secondary school administrators in Washington State, United States, and in Victoria, Australia, this study compared aspects of the school drug policy environment in the 2 states. Documented substance-use policies were prevalent in Washington and Victoria but less prevalent in primary schools, especially in Victoria. Victorian school policy-setting processes were significantly more likely to involve teachers, parents, and students than processes in Washington schools. Consistent with expectations based on their respective national drug policy frameworks, school drug policies in Washington schools were more oriented toward total abstinence and more frequently enforced with harsh punishment (such as expulsion or calling law enforcement), whereas policies in Victorian schools were more reflective of harm-minimization principles. Within both states, however, schools more regularly used harsh punishment and remediation consequences for alcohol and illicit-drug violations compared to tobacco policy violations, which were treated more leniently.

Financial crime in South Africa

During the 1990s economic crime began to spiral in South Africa. This phenomenon coincided with the country's transition to a democratic state. The article outlines a number of steps that South Africa took to align its laws with international standards and to improve the legal tools of law enforcement to address the crime wave. A number of successes, for instance the improvement in tax morality, are pointed out but it is argued that co-ordination and co-operation between law enforcement agencies require more attention.

Designing effective training programs for investigative interviewers of children

'Best-practice' guidelines for conducting investigative interviews with children are well established in the literature, yet few investigative interviewers actually adhere to such guidelines in the field. One of the problems is that little discussion has focused on how such guidelines are learned and sustained by professionals. To address this concern, the current article reviews the key elements of interview training programs that are known to promote competent interviewing. These elements include: (i) the establishment of key principles or beliefs that underpin effective interviewing, (ii) the adoption of an interview framework that maximises narrative detail, (iii) clear instruction in relation to the application of the interview framework, (iv) effective ongoing practice, (v) expert feedback and (vi) regular evaluation of interviewer performance. A description and justification of each element is provided, followed by broad recommendations regarding how these elements can be implemented by police and human service organisations in a cost-effective manner.

Integrating job stress and social exchange theories to predict employee strain in reformed public sector contexts

This research examines the organizational characteristics that contribute to employee wellbeing in public sector agencies that have undergone substantial organizational change. Two studies were undertaken, the first involving 2,466 police officers working in a state-based law enforcement agency, whereas the second comprised 1,010 occupationally diverse employees working in a State Government authority. The research was guided by a theoretical framework that begins with a model underpinning many large-scale job stress investigations—the job strain model (JSM)—and is expanded to incorporate widely used social exchange variables (i.e., psychological contract breach and organizational fairness). The results of hierarchical regression analyses from both studies confirm the value of the JSM. There was also strong support for extending the JSM to include the breach and fairness variables; however, proposed interactions between job demands and organizational fairness failed to add to the explanatory value of the model. The implications of these results particularly for public sector organizations that have undergone extensive reforms consistent with New Public Management are discussed.

A clarification of the ERI model : the importance of personality

The present study aimed to investigate the role of personality in the etfort-reward imbalance model along with the construct validity of overcommitment in relation to Type A behaviour. The study sample consisted of 898 operational law enforcement persolllel from a large Australian police service. Factor analysis revealed that the overcommitment construct was psychologically related to, but distinct from, the Type A dimensions achievement striving, impatience-irritability and hostility despite the hypothesised interrelatedness of the measures. Multiple regression analyses including tests for curvilinear effects revealed that the Type A dimensions made a significant improvement to the prediction of employee wellbeing and job satisfaction, The results of the study provide theoretical implications in terms of the augmentation of the effort-reward imbalance model.

The dimensionality of self-rated employee performance : an integrated view

This study addresses the debate in the literature regarding the dimensionality of the job performance construct. The sample comprised 647 public servants from a state-based law enforcement organisation. Exploratory and confirmatory factor analyses delineate a four:factor structure, consisting of in-role behaviour, organisational citizenship behaviour directed towards (1) individuals or (2) the organisation, and a distinct latent variable deemed counter-productive work behaviour (CWB). The pattern of correlations among the four performance dimensions and between the performance dimensions and attitudes support the construct and discriminant validity of the four performance dimensions. Further, the .findings propose that CWB is a core, not discretionary, dimension of performance.

Procedural justice and affect intensity : understanding reactions to regulatory authorities

Why is it that some people respond in a more negative way to procedural injustice than do others, and why is it that some people go on to defy authority while others in the same situation do not? Personality theorists suggest that the psychological effect of a situation depends on how a person interprets the situation and that such differences in interpretation can vary as a function of individual difference factors. For example, affect intensity—one’s predisposition to react more or less emotionally to an event—is one such individual difference factor that has been shown to influence people’s reactions to events. Cross-sectional survey data collected from (a) 652 tax offenders who have been through a serious law enforcement experience (Study 1), and (b) 672 citizens with recent personal contact with a police officer (Study 2), showed that individual differences in ‘affect intensity’ moderate the effect of procedural justice on both affective reactions and compliance behavior. Specifically, perceptions of procedural justice had a greater effect in reducing anger and reports of non-compliance among those lower in affect intensity than those higher in affect intensity. Both methodological and theoretical explanations are offered to explain the results, including the suggestion that emotions of shame may play a role in the observed interaction.

The money laundering risk posed by low-risk financial products in South Africa : findings and guidelines

Purpose – The purpose of this paper is to investigate the level and nature of criminal abuse of financial products that are classified as posing a low anti-money laundering/combating of financing of terrorists (AML/CFT) risk in South Africa to determine the effectiveness of the simplified due diligence measures that apply to these products.

Design/methodology/approach – The paper presents empirical research on the views of bank officials and law enforcement officials regarding the criminal abuse of South African financial products that are subject to simplified customer due diligence controls.

Findings – South Africa's AML/CFT laws allow certain deposit-taking institutions and money remitters to implement simplified customer due diligence measures in relation to specific low-risk products that are mainly designed to allow previously unbanked persons to access financial services. The paper finds that the products have been abused by criminals but that the incidence of such abuse and the amounts involved are low. The paper investigates possible weaknesses in the current system that allow limited criminal abuse to occur. It concludes with a number of guidelines that emerge from the study and are of value to regulators that wish to implement a similar system.

Originality/value – The South African AML/CFT scheme in relation to low-risk products is of interest to many international regulators that are grappling with the interplay between effective AML/CFT controls and the impact of strict controls on the ability of socially and economically excluded persons to access appropriate financial services. This paper provides evidence that appropriately designed controls can facilitate financial inclusion while limiting the risk of criminal abuse.

Identifying the predictors of employee health and satisfaction in an NPM environment : testing a comprehensive and non-linear demand-control-support model

The Demand-Control-Support (DCS) model is investigated in the context of police officers working within an organization that has relatively widespread uptake of New Public Management (NPM) practices. A survey of 479 police officers from two geographic regions was undertaken and the results indicate that the DCS offers a simple, yet powerful, framework for identifying the conditions to be managed in an NPM-oriented environment. Job control and work-based support predict all four target variables, strengthening the view that decision-making latitude and support from supervisors and colleagues represent critical resources for promoting the well-being, satisfaction and commitment of public sector employees.

Extracting fingerprint features using textures

Personal identification of individuals is becoming increasingly adopted in society today. Due to the large number of electronic systems that require human identification, faster and more secure identification systems are pursued. Biometrics is based upon the physical characteristics of individuals; of these the fingerprint is the most common as used within law enforcement. Fingerprint-based systems have been introduced into the society but have not been well received due to relatively high rejection rates and false acceptance rates. This limited acceptance of fingerprint identification systems requires new techniques to be investigated to improve this identification method and the acceptance of the technology within society. Electronic fingerprint identification provides a method of identifying an individual within seconds quickly and easily. The fingerprint must be captured instantly to allow the system to identify the individual without any technical user interaction to simplify system operation. The performance of the entire system relies heavily on the quality of the original fingerprint image that is captured digitally. A single fingerprint scan for verification makes it easier for users accessing the system as it replaces the need to remember passwords or authorisation codes. The identification system comprises of several components to perform this function, which includes a fingerprint sensor, processor, feature extraction and verification algorithms. A compact texture feature extraction method will be implemented within an embedded microprocessor-based system for security, performance and cost effective production over currently available commercial fingerprint identification systems. To perform these functions various software packages are available for developing programs for windows-based operating systems but must not constrain to a graphical user interface alone. MATLAB was the software package chosen for this thesis due to its strong mathematical library, data analysis and image analysis libraries and capability. MATLAB enables the complete fingerprint identification system to be developed and implemented within a PC environment and also to be exported at a later date directly to an embedded processing environment. The nucleus of the fingerprint identification system is the feature extraction approach presented in this thesis that uses global texture information unlike traditional local information in minutiae-based identification methods. Commercial solid-state sensors such as the type selected for use in this thesis have a limited contact area with the fingertip and therefore only sample a limited portion of the fingerprint. This limits the number of minutiae that can be extracted from the fingerprint and as such limits the number of common singular points between two impressions of the same fingerprint. The application of texture feature extraction will be tested using variety of fingerprint images to determine the most appropriate format for use within the embedded system. This thesis has focused on designing a fingerprint-based identification system that is highly expandable using the MATLAB environment. The main components that are defined within this thesis are the hardware design, image capture, image processing and feature extraction methods. Selection of the final system components for this electronic fingerprint identification system was determined by using specific criteria to yield the highest performance from an embedded processing environment. These platforms are very cost effective and will allow fingerprint-based identification technology to be implemented in more commercial products that can benefit from the security and simplicity of a fingerprint identification system.

Evolving nature of fraud investigation and prevention

This thesis is concerned with the evolution of fraud investigation and prevention in light of the advances in computing technology. These recent advances have impacted upon traditional fraud offences as well as creating a range of new crimes. The financial significance of fraud is growing whereas law enforcement and the judicial system appear to be unable to meet the demands of these emerging crimes and its victims. This research compares the responses of our present and future investigators with those of our current business leaders from the government and the commercial sectors. This research establishes the needs of corporate decision-makers and the attitudes of police with regard to fraud. Data relating to persons arrested and convicted of fraud was also analysed to identify the issues that may be responsible for the non-reporting of offences to police by victims. The research found that victims are seeking solutions that are not available through law enforcement, for example financial compensation. Law enforcement also under-utilises the potential of proactive responses to prevent offences and they are reluctant to acknowledge the benefits of preventative measures and to incorporate this strategy within criminal investigation training programmes. The lack of deterrence offered by the judicial system does not make the situation any better. The police function is still primarily a reactive one. In order to overcome fraud and to be able to adapt to changes there needs to be collaboration between stakeholders. This requires a joint effort from the police, government, commerce and the victims of fraud. An innovative model involving stakeholders has been formulated that represents an alternative to the current system. This approach utilises the financial resources and expertise from the commercial sector as well as the skills of criminal investigators from the police. This means adopting a combined package of both reactive and proactive measures in order to minimise the impact of fraud. This model will be adaptive and will be able to accommodate any future requirements arising out of further inevitable advances in computer technology.

Drawing lines in the sea : the laws that govern traffic on the world’s oceans can be as difficult to shape as water

Since World War II, however, the term has increasingly referred to law enforcement operations, as a means to enforce trade sanctions, to prevent the movement of weapons of mass destruction (WMDs), and particularly in the Caribbean Sea, to prevent the smuggling of illicit drugs. Such ambiguity should allow flexibility when deciding whom should be targeted, as well as allowing states with veto powers in the UN Security Council, which may legitimately ship nuclear weapons and materials, to avoid being targeted as long as they do not export WMDs to rogue states or non-state groups or individuals.2 The ISPS Code was created under the auspices of the International Maritime Organization (IMO) and is part of the 1974 Safety of Life at Sea Convention (SOLAS) concerning the safety of merchant ships.

Investigative interviewing of children : barriers to adopting 'best-practice' guidelines

This research examined the global difficulties of investigative interviewers in adhering to best-practice guidelines (i.e. open-ended questions) when interviewing children about abuse. It demonstrated that the importance of, and rationale for, using open-ended questions is not well understood by investigative interviewers, nor are they adequately reinforced with police organisations.

Police officers' questioning of children about repeated abuse

This thesis examined the perceptions of police and legal professionals regarding how police officers should and do interview children about repeated abuse. It also examined the actual performance of police interviewers in mock and field interviews to understand the reason for interviewer's difficulties and how interview strategy can be improved. The portfolio examines and discusses the complexities associated with assessing the risk of sexual recidivism among different sex offender populations - adult sex offenders, sex offenders with an intellectual disability, adolescent sex offenders and indigenous sex offenders. Four case studies are presented.
