Abstract
Purpose
While behaviour sequence analysis (BSA) is popular, it is not without limitations, namely, the level of detail required and time taken to run analyses; therefore, this paper aims to outline a novel method, using 30 serial homicide cases as a worked example.
Design/methodology/approach
Temporal analysis methods are becoming increasingly popular in applied forensic and criminological research. In recent years, BSA has become a widely used approach.
Findings
Waypoint sequencing provides a streamlined version of the traditional BSA approach, allowing for fewer behaviours to be included and providing a clearer overview of the main behaviours of interest.
Practical implications
Waypoint sequencing is shown in the current paper through serial killer research to show how to conduct the analyses and how it is effective in current investigations by expediting the process and allowing quicker analysis to facilitate current investigations.
Originality/value
The current research provides a novel approach to sequence analysis that is more useful in applied settings as it requires fewer behaviours or events than traditional BSA.

Abstract
Purpose
Behaviours occur across complex, dynamic timelines. Research methods to analyse these complex timelines have repeatedly used behaviour sequence analysis (BSA) as a primary method. Traditional BSA outputs, however, are limited in that they do not show how prevalent a behaviour sequence is throughout a sample or group. Until now, how many people in a sample showed the sequence was not analysed and reported. This paper aims to provide a new metric to calculate prevalence scores in BSA data sets.
Design/methodology/approach
Open access recorded responses including nonverbal communication of deceptive and truthful individuals were analysed initially with a standard BSA approach and then the prevalence scores of transitions were calculated.
Findings
Prevalence scores offered new insights into the distribution of sequences across groups. The prevalence score showed differences in which transitions were seen across the truthful and guilty samples. This offers new approaches to analysing nonverbal communication.
Originality/value
This is the first paper to provide a prevalence score for BSA research and show how it can be used in applied research. The current prevalence score metric is provided and suggested for all future research into sequences.

Abstract
Purpose
Emergency service dispatchers perform a vital role in assisting callers by helping them through the emergency they are in and ensuring the delivery of first responders. If an emergency caller prematurely hangs up a call, before the arrival of first responders, it can impact a dispatcher’s ability to provide them with assistance. This paper aims to understand why staged callers, who are attempting to cover up a crime, and authentic callers hang up by identifying which linguistic and behavioural indicators occur prior to the end of a call.
Design/methodology/approach
A sample of 40 emergency calls (20 staged; 20 authentic) related to health and welfare emergencies were analysed with a temporal measure known as indicator waves. This provided a means to identify which indicators occurred above the level expected by chance near the end of authentic and staged calls.
Findings
The results of the current study show that the indicators that proceeded hanging up in authentic calls reflected the nature of the situation (e.g. nonurgency wherein the victim is deceased or is in a stable condition). Whereas the indicators that proceeded hanging up in staged calls focused on the “staging” aspect of the incident by accounting for forensic evidence that could be incriminating.
Originality/value
The identification of indicators that occur before the end of staged and authentic calls provides further insight into the differences between the two call types and offers opportunities for further research, potentially leading to application.

Abstract
Purpose
The purpose of this paper is to outline a variety of related methods for helping with criminal (cold) case investigations. Despite the best efforts of police investigations, many cases around the world run out of leads and go cold. While many police departments around the world have developed specialist groups and task forces, academics have also been developing new methods that can assist with investigations.
Design/methodology/approach
Cold cases, by their very nature, typically comprise incomplete data sets that many traditional statistical methods are not suited to. Groups of researchers have therefore developed temporal, dynamic analysis methods to offer new insights into criminal investigations. These methods are combined into a timeline toolkit and are outlined in the current paper.
Findings
Methods from the timeline toolkit have already been successfully applied to many cold cases, turning them back into current cases. In this paper, two real-world cold cases are analysed with methods from the timeline toolkit to provide examples of how these methods can be applied in further cold cases.
Originality/value
Methods from the timeline toolkit provide a novel approach to investigating current and cold cases. This review provides academics and practitioners with a guide to begin using and developing these methods and forming successful collaborations with police departments and cold case task forces. The methods are also suitable for wider groups and to use in their investigations.

Abstract
The modern workplace contains many physical and interpersonal hazards to employee physical and psychological health/well-being. This chapter integrates the literatures on occupational safety (i.e., accidents and injuries) and mistreatment (physical violence and psychological abuse). A model is provided linking environmental (climate and leadership), individual differences (demographics and personality), motivation, behavior, and outcomes. It notes that some of the same variables have been linked to both safety and mistreatment, such as safety climate, mistreatment climate, conscientiousness, and emotional stability.

Looking beyond the immediate future, which for the world of information and computing means the next five years, is hazardous. This paper attempts to present a vision of some aspects of the information world of the medium future. 2010 has been chosen as the date, rather than 2001, since the likely events of the earlier date can be fairly well predicted.

Abstract
This chapter investigates the nature of the transformation of macroeconomics by focusing on the impact of the Great Depression on economic doctrines. There is no doubt that the Great Depression exerted an enormous influence on economic thought, but the exact nature of its impact should be examined more carefully. In this chapter, I examine the transformation from a perspective which emphasizes the interaction between economic ideas and economic events, and the interaction between theory and policy rather than the development of economic theory. More specifically, I examine the evolution of what became known as macroeconomics after the Depression in terms of an ongoing debate among the “stabilizers” and their critics. I further suggest using four perspectives, or schools of thought, as measures to locate the evolution and transformation; the gold standard mentality, liquidationism, the Treasury view, and the real-bills doctrine. By highlighting these four economic ideas, I argue that what happened during the Great Depression was the retreat of the gold standard mentality, the complete demise of liquidationism and the Treasury view, and the strange survival of the real-bills doctrine. Each of those transformations happened not in response to internal debates in the discipline, but in response to government policies and real-world events.

Abstract
Very little Australian literature looks at women as leaders in education. Using theoretical viewpoints emerging out of a biographical and historical analysis, it is possible to construct a more inclusive model of leadership which includes both men and women in the past. Mapping such a process historically and biographically can give a detailed assessment of the social, historical and political dimensions of particular women leaders′ lives and also develop a theoretical framework, which gives equal status to the leadership experiences more common to women. Presents a historical narrative where recording lives raises critical questions at the same time as it unearths new evidence of the history of women educationists in Australia.
