Improving the competency of police officers in conducting investigative interviews with children

Despite the provision of 'best-practice' guidelines regarding conducting interviews with children, research indicates that most investigative interviews do not adhere to these guidelines. To date, there has been little discussion in the literature of the conditions that are needed to promote and sustain expertise in forensic interviewing. The current paper addresses this limitation by describing the main factors preventing the adoption of 'best-practice' interview guidelines. A description of these barriers (and the literature that supports them) forms the basis for the review component of this paper as well as the subsequent recommendations for change.

An examination of police officers' notes of interviews with alleged child abuse victims

This study provided a critical examination of handwritten records (notes) of interviews contained in a sample of 89 police case files about alleged child abuse. Some of the notes examined related to initial disclosure (complaint) interviews which were not electronically recorded and were meant to be recorded verbatim. Notes of electronically recorded interviews, which merely constituted a convenient summary of the case details, were also examined. Collectively, the analyses focused on the accessibility, completeness and accuracy of the notes, and the degree to which the interviewers' questions and witnesses' answers were differentiated. In relation to the disclosure interviews, a substantial proportion of these were not accessible. Of those where the notes were obtained, the detail recorded was not a complete record of conversation, and there was often poor delineation of questions and responses. Analysis of the electronically recorded interviews showed that these were not an entirely accurate summary of event details even though the note takers' sole task was to document the interview. The implications of these findings are discussed.

Police stress : the role of psychological contract and perceptions of fairness

Purpose – The overall purpose of this paper is to examine the extent to which breaches in psychological contracts and perceptions of organizational fairness account for variations in job stress experienced by operational police officers (as measured by psychological distress and employee performance), after controlling for the variance associated with more established job stressors (i.e. job demands, job control and social support).

Design/methodology/approach – This study is based on data collected through a self-report survey involving operational members of a large Australian police force (n=582).

Findings – Results of hierarchical multiple regression analyses indicate that vast majority of explained variance in psychological distress and extra-role performance is attributed to the additive effects of demand, control, and support. Furthermore, only one of the social exchange dimensions (interpersonal fairness) is predictive of either target variable.

Research limitations/implications – The limitations that need to be taken into account are the cross-sectional nature of the study design and the focus on a single police service.

Practical implications – Despite the generally weak support for the social exchange variables, there are signs that dimensions of justice (particularly interpersonal justice) should be included in future police-stress investigations. The results also suggest that job characteristics such as job demand, job control and social support should be taken into account when developing strategies to prevent and/or reduce chronic job stress in policing services.

Originality/value – This is one of the first studies to examine the relationships between psychological contract breach, perceptions of fairness and police stress.

Traffic fatalities and public sector corruption

Traffic accidents result in 1 million deaths annually worldwide, though the burden is disproportionately felt in poorer countries. Typically, fatality rates from disease and accidents fall as countries develop. Traffic deaths, however, regularly increase with income, at least up to a threshold level, before declining. While we confirm this by analyzing 1,356 country-year observations between 1982 and 2000, our purpose is to consider the role played by public sector corruption in determining traffic fatalities. We find that such corruption, independent of income, plays a significant role in the epidemics of traffic fatalities that are common in relatively poor countries.

State police in a state of change : remaking the entrepreneurial officer

Questions concerning how to govern police practice have never been more pressing or more fluid. This study locates contemporary developments in police accountability techniques within a broader analysis of the historical circumstances shaping the changing techniques for governing police. The recent pluralisation of police accountability pr.ocesses and structures is examined through the application of governmentality studies. Drawing on a comparative analysis of two Australian States the book provides a detailed account of the development of governmental techniques for 'making up' the entrepreneurial officer. While such a governmental project is not implemented unproblematically the book concludes that the attempt to shape the development of the entrepreneurial officer through the managerialisation of governing presents distinct possibilities for a new 'politics of policing' that fosters deliberative and reflective police practice.

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.

Humanoid traffic control robot

A traffic control device in the form of a humanoid character robot, doll or dummy is used to warn driver of danger ahead on the road. The device can be used on roads, streets and in other sites where there are moving vehicles. The robotic device informs drivers of impending danger by moving its arms and sounding an acoustic alarm. In this way the robot can simulate a policeman or road flagging operator. The device may also include speed detection and preferably speed indication means. The robot may make decisions based on the detected speed of a vehicle and the limit for the area in operating the arms and sound warning means. The robot may also be equipped with a camera or video. The robot may also be controlled wirelessly.

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.

Spam filtering for network traffic security on a multi-core environment

This paper presents an innovative fusion-based multi-classifier e-mail classification on a ubiquitous multicore architecture. Many previous approaches used text-based single classifiers to identify spam messages from a large e-mail corpus with some amount of false positive tradeoffs. Researchers are trying to prevent false positive in their filtering methods, but so far none of the current research has claimed zero false positive results. In e-mail classification false positive can potentially cause serious problems for the user. In this paper, we use fusion-based multi-classifier classification technique in a multi-core framework. By running each classifier process in parallel within their dedicated core, we greatly improve the performance of our multi-classifier-based filtering system in terms of running time, false positive rate, and filtering accuracy. Our proposed architecture also provides a safeguard of user mailbox from different malicious attacks. Our experimental results show that we achieved an average of 30% speedup at an average cost of 1.4 ms. We also reduced the instances of false positives, which are one of the key challenges in a spam filtering system, and increases e-mail classification accuracy substantially compared with single classification techniques.

Police officers' note-taking of interviews with alleged child abuse victims

The field and experimental studies for this thesis revealed that: the quality of documentation of 'disclosure' (initial) interviews with child abuse witnesses was poor; under optimal note-taking conditions, verbatim records of interview were still not provided, and considerable variability was observed in the quality of notes and strategies employed to document content and structure. The portfolio presents four case studies to illustrate similarities and/or differences between offence behaviour in child sex offenders with impairment, and the offence behaviours that characterise Canter et al.'s intimate, criminal-opportunistic and aggressive type offenders.

An optimal transportation routing approach using GIS-based dynamic traffic flows

This paper examines the value of real-time traffic information gathered through Geographic Information Systems for achieving an optimal vehicle routing within a dynamically stochastic transportation network. We present a systematic approach in determining the dynamically varying parameters and implementation attributes that were used for the development of a Web-based transportation routing application integrated with real-time GIS services. We propose and implement an optimal routing algorithm by modifying Dijkstra’s algorithm in order to incorporate stochastically changing traffic flows. We describe the significant features of our Web application in making use of the real-time dynamic traffic flow information from GIS services towards achieving total costs savings and vehicle usage reduction. These features help users and vehicle drivers in improving their service levels and productivity as the Web application enables them to interactively find the optimal path and in identifying destinations effectively.

Australian police responses to transnational crime and terrorism

This chapter outlines the Australian federal policing and allied agency responses to international drug trafficking activity and terrorism. The chapter is situated alongside a broader analysis of the structure of each key agency and the various interagency enforcement mechanisms established domestically and internationally to improve enforcement performance.

An analysis of police officers decisions about whether to refer cases of child abuse for prosecution

In many jurisdictions, police officers are responsible for deciding whether cases of child abuse are referred for potential prosecution. Such discretion justifies the need to scrutinise these professionals' decisions to determine if they are consistent with the scientific eyewitness memory literature. Prior research has shown that interviewer questioning is one of the most critical factors impacting the reliability of child witness statements. Hence, we asked: 'To what degree do officers' consider the quality of interviewer questions when making case authorisation decisions?'. In order to answer this question, we conducted a thematic analysis to identify issues referred to in a sample of documented police correspondence (n=33) about potential prosecution of child abuse cases. Two key themes emerged: the existence of corroborative evidence and whether the suspect denied the allegations. Questioning technique, however, was not considered. All but one decision that referred to interview process focused on the presentation of the witness, even though the witness interviews (as a whole) did not adhere to recommended best-practice guidelines. The implications of these findings are discussed.
