The purpose of this paper is to identify offender typologies based on aspects of the offenders’ psychopathology and their associations with crime scene behaviours using data derived from the National Confidential Enquiry into Suicide and Safety in Mental Health concerning homicides in England and Wales committed by offenders in contact with mental health services in the year preceding the offence (n=759).

The authors used multiple correspondence analysis to investigate the interrelationships between the variables and hierarchical agglomerative clustering to identify offender typologies. Variables describing: the offenders’ mental health histories; the offenders’ mental state at the time of offence; characteristics useful for police investigations; and patterns of crime scene behaviours were included.

Results showed differences in the offenders’ histories in relation to their crime scene behaviours. Further, analyses revealed three homicide typologies: externalising, psychosis and depression.

These typologies may assist the police during homicide investigations by: furthering their understanding of the crime or likely suspect; offering insights into crime patterns; provide advice as to what an offender’s offence behaviour might signify about his/her mental health background. Findings suggest information concerning offender psychopathology may be useful for offender profiling purposes in cases of homicide offenders with schizophrenia, depression and comorbid diagnosis of personality disorder and alcohol/drug dependence.

Empirical studies with an emphasis on offender profiling have almost exclusively focussed on the inference of offender demographic characteristics. This study provides a first step in the exploration of offender psychopathology and its integration to the multivariate analysis of offence information for the purposes of investigative profiling of homicide by identifying the dominant patterns of mental illness within homicidal behaviour.

The purpose of this paper is to evaluate and improve the quality and the reliability of pre‐treatment quality controls of an efficient technique of radiotherapy called IMRT (intensity‐modulated radiation therapy). The aim is then to determine if the controls can be safely reduced while keeping an optimal level of quality.

The statistical process control method (SPC) was applied to quality assurance in IMRT. In order to characterize prostate and head‐and‐neck treatment process variability, individual value control charts and moving‐range control charts were established.

Control charts showed that prostate and head‐and‐neck treatment processes are only subject to random causes of variability, which means they are statistically controlled. It was proved that both processes are statistically stable and capable.

The paper shows that SPC is an efficient method to objectively determine if quality controls can be reduced.

The purpose of this article is to review the status of current research on how disaster response can best adapt to the urban environment. It looks specifically at water supply assistance, analysing the role and interaction of the various stakeholders and, in particular, the relationship between aid agencies and water utilities.

The review is based on published and unpublished documents produced on the response to emergencies having taken place in developing countries in the last 30 years.

The article reproduces statistical data on the rising trends in the incidence of disasters in cities, which emphasizes the relevance of the subject. It also shows that the experience accumulated in the last decade on the response to urban disasters suggests that partnerships between water utilities and aid agencies are beneficial. But the means to achieve this partnership require a more in‐depth analysis.

This review is based only on the literature and should be completed by a case study research in order to support and further develop its theses.

While the level of access to urban services in the developing countries has been extensively researched in “normal times”, there has been little exploration of its role in crisis situations. This article points out the value of such research and recommends that more analysis is carried out.

The main purpose of this paper is to assess the patterns in the public discourse of successful chief executive officers (CEOs) in terms of performance, with the CEO's strengths and aspects to improve.

This paper aligns with the literature that appraises CEO public discourse and relevance. From the literature review, the strategic levers in CEO discourse toward high performance are identified. The CEO letters in the period 2017–2019 of the top 25 best performing CEOs (BPCs) according to Harvard Business Review ranking 2019 are qualitatively examined through a multiple close reading analytical technique and multiple correspondence analysis (MCA) is applied to assess the patterns.

The paper delivers a three-dimensional model representing how the identified strategic levers are articulated by BPCs in the BPC's discourse following diverse patterns. This paper points out BPC's strengths, among them a high level of moral reasoning compared to previous studies and improvable areas such as the extended absence of autocritique at the firm and personal level or the lack of leverage on the need for agility and proactive adaption.

This paper contributes further CEO awareness of the strategic role of the discourse and offers clues to enhance CEO awareness, as well as criteria for boards of directors to appraise CEO discourse.

Adopting a novel approach, this paper addresses the strategic levers triggered by CEOs in their letters from a managerial implication perspective, providing relevant theoretical insight on how they are articulated.
