Abstract
Purpose
The purpose of this systematic review is to evaluate the extant literature on depression and anxiety disorders in police using a multinational data set to determine whether the prevalence of these trauma-related disorders (TRMDs) is elevated in comparison to the general population.
Design/methodology/approach
Systematic review was employed in combination with best-evidence narrative synthesis to evaluate these hypotheses.
Findings
Despite wide variability in prevalence outcomes across the literature, strong evidence supports the hypothesis that the prevalence of depression is elevated in police, whereas moderate evidence supports the same hypothesis regarding anxiety. Preliminary evaluation of commonly examined predictive factors for each disorder demonstrated weak and inconsistent associations between these TRMDs and sociodemographic factors. No studies evaluated the relationship between incident-related factors (e.g. severity or frequency of exposure) and TRMDs, thus, at present, the literature on police is almost entirely unable to address the question of whether the prevalence of these disorders in police is influenced by exposure to work-related trauma.
Research limitations/implications
The findings highlight a critical need for future work to address incident-related factors in predicting symptoms of depression and anxiety in police samples to determine whether these disorders bear a unique relationship to work-related traumatic exposure. Such work will significantly benefit the design and implementation of successful prevention and intervention strategies in the workplace.
Originality/value
The present review provides a comprehensive synthesis of a highly variable literature, highlighting critical gaps in our current knowledge of TRMDs in police and suggesting numerous avenues for future study.

Abstract
Stress and the military go hand-in-hand, particularly in combat environments. While some personality traits or types weaken relationships between stress and performance, others, such as psychopathy, may strengthen them. In the present chapter, we consider the ramifications of individuals with high levels of psychopathy or psychopathic tendencies in the military with regard to both their own stress and performance and that of those around them. We discuss different reactions to psychological and physical stress, as well as the implications of psychopathic tendencies as they relate to current military issues, including gender, leadership, teamwork, turnover, post-traumatic stress disorder, and suicide. By juxtaposing relevant research findings on stress and psychopathy, we conclude that psychopathic tendencies should have neither uniformly negative nor positive effects on stress and performance in the military. Rather, effects on such individuals and the peripheral others with whom they interact will likely vary greatly depending on numerous factors.

Abstract
Design thinking has become something of a buzz word in innovation discussions and has recently also invested occupied education spaces. In this chapter we briefly compare design thinking to problem-based learning (PBL) and enquiry-based learning (EBL) approaches to problem solving in education before focusing on the approach itself and current debates about its meaning and significance. This chapter focuses particular attention on the problem finding aspect of design thinking and its integration of creative methods for solving a range of tame to wicked problems in a variety of spaces. We ground our analysis in three environments of design thinking and five specific cases of application across education sectors from primary through to university. The examples focus on the generative potential of design thinking for all students and especially those from non-design disciplines. It is this capacity of design thinking to complement existing pedagogies and provide inspiration for change and innovation that is the strength of the model.

Abstract
Purpose
This paper aims to present a methodology for the detection and categorisation of metal powder particles that are partially attached to additively manufactured lattice structures. It proposes a software algorithm to process micro computed tomography (µCT) image data, thereby providing a systematic and formal basis for the design and certification of powder bed fusion lattice structures, as is required for the certification of medical implants.
Design/methodology/approach
This paper details the design and development of a software algorithm for the analysis of µCT image data. The algorithm was designed to allow statistical probability of results based on key independent variables. Three data sets with a single unique parameter were input through the algorithm to allow for characterisation and analysis of like data sets.
Findings
This paper demonstrates the application of the proposed algorithm with three data sets, presenting a detailed visual rendering derived from the input image data, with the partially attached particles highlighted. Histograms for various geometric attributes are output, and a continuous trend between the three different data sets is highlighted based on the single unique parameter.
Originality/value
This paper presents a novel methodology for non-destructive algorithmic detection and categorisation of partially attached metal powder particles, of which no formal methods exist. This material is available to download as a part of a provided GitHub repository.

Abstract
Purpose
The importance of integrating sustainability into business activities rises continuously. In addition to an established focus on forward logistics, there is a growing awareness of reverse logistics. Reverse logistics ensures sustainable practices and increases competitiveness for companies, but it also comes with challenges. Therefore, the implementation of reverse logistics is associated with uncertainties. This paper aims to fill this gap by analyzing the development and comprehensive potential of reverse logistics as a sustainability tool.
Design/methodology/approach
To bridge the research gap, a real-time Delphi study was conducted. Through an extensive desk research, semi-structured interviews and an expert workshop, 14 projections for the German food sector of 2040 were created. A total of 49 experts in the field of logistics, reverse logistics and food logistics assessed the future projections concerning estimated probability, impact and desirability of occurrence.
Findings
The findings derived lead to three possible future scenarios as well as potential drivers and barriers that food companies, the government and society need to consider to enable a successful transition toward implementing reverse logistics in food supply chains.
Originality/value
The study examined the future role of reverse logistics as a sustainability tool in food supply chains. The results serve as a framework for decision-making on the sustainable orientation of business practices, leading to increased competitiveness and resilient business strategy. Several implications are derived for practitioners, policymakers and society to promote reverse logistics. Methodologically, this study extends existing Delphi methods by conducting a quantitative dissent and sentiment analysis, considering various surface-level and deep-level diversity characteristics.

Abstract
Purpose
Technology upgrade has been adopted as a strategy for technology vendors to modify and improve their incumbent technologies. However, user resistance is widespread in practice. In order to understand user technology upgrade behavior, this study integrates the retrospective and prospective sides of actions and proposes an inertia-mindfulness ambidexterity perspective to explore the antecedents of technology upgrade.
Design/methodology/approach
An online survey was conducted to collect data from 520 Microsoft Windows users to test this research model. Structural equation modeling (SEM) approach was used to evaluate measurement model and structural model.
Findings
Inertia can induce individuals' psychological reactance and thus reduce their intention to upgrade. In contrast, mindfulness can decrease users' psychological reactance and then motivate them to upgrade to a new version of technology. Finally, individuals' dissatisfaction with the current version of technology would weaken the negative impact of psychological reactance on upgrade intention.
Originality/value
This study generates an inertia-mindfulness ambidexterity perspective to investigate the factors that influence user technology upgrade intention from both retrospective and prospective sides and then identifies psychological reactance as underlying mechanism to explain how inertia and mindfulness work. Finally, this study posits that user dissatisfaction with current version of technology can moderate the relationship between psychological reactance and technology upgrade intention.
