Abstract
Purpose
Rehearsing practical site operations is without doubt one of the most effective methods for minimising planning mistakes, because of the learning that takes place during the rehearsal activity. However, real rehearsal is not a practical solution for on‐site construction activities, as it not only involves a considerable amount of cost but can also have adverse environmental implications. One approach to overcoming this is by the use of virtual rehearsals. The purpose of this paper is to investigate an approach to simulation of the motion of cranes in order to test the feasibility of associated construction sequencing and generate construction schedules for review and visualisation.
Design/methodology/approach
The paper describes a system involving two technologies, virtual prototyping (VP) and four‐dimensional (4D) simulation, to assist construction planners in testing the sequence of construction activities when mobile cranes are involved. The system consists of five modules, comprising input, database, equipment, process and output, and is capable of detecting potential collisions. A real‐world trial is described in which the system was tested and validated.
Findings
Feedback from the planners involved in the trial indicated that they found the system to be useful in its present form and that they would welcome its further development into a fully automated platform for validating construction sequencing decisions.
Research limitations/implications
The tool has the potential to provide a cost‐effective means of improving construction planning. However, it is limited at present to the specific case of crane movement under special consideration.
Originality/value
This paper presents a large‐scale, real life case of applying VP technology in planning construction processes and activities.

Abstract
Purpose
This paper presents a survey of research into interactive robotic systems for the purpose of identifying the state of the art capabilities as well as the extant gaps in this emerging field. Communication is multimodal. Multimodality is a representation of many modes chosen from rhetorical aspects for its communication potentials. The author seeks to define the available automation capabilities in communication using multimodalities that will support a proposed Interactive Robot System (IRS) as an AI mounted robotic platform to advance the speed and quality of military operational and tactical decision making.
Design/methodology/approach
This review will begin by presenting key developments in the robotic interaction field with the objective of identifying essential technological developments that set conditions for robotic platforms to function autonomously. After surveying the key aspects in Human Robot Interaction (HRI), Unmanned Autonomous System (UAS), visualization, Virtual Environment (VE) and prediction, the paper then proceeds to describe the gaps in the application areas that will require extension and integration to enable the prototyping of the IRS. A brief examination of other work in HRI-related fields concludes with a recapitulation of the IRS challenge that will set conditions for future success.
Findings
Using insights from a balanced cross section of sources from the government, academic, and commercial entities that contribute to HRI a multimodal IRS in military communication is introduced. Multimodal IRS (MIRS) in military communication has yet to be deployed.
Research limitations/implications
Multimodal robotic interface for the MIRS is an interdisciplinary endeavour. This is not realistic that one can comprehend all expert and related knowledge and skills to design and develop such multimodal interactive robotic interface. In this brief preliminary survey, the author has discussed extant AI, robotics, NLP, CV, VDM, and VE applications that is directly related to multimodal interaction. Each mode of this multimodal communication is an active research area. Multimodal human/military robot communication is the ultimate goal of this research.
Practical implications
A multimodal autonomous robot in military communication using speech, images, gestures, VST and VE has yet to be deployed. Autonomous multimodal communication is expected to open wider possibilities for all armed forces. Given the density of the land domain, the army is in a position to exploit the opportunities for human–machine teaming (HMT) exposure. Naval and air forces will adopt platform specific suites for specially selected operators to integrate with and leverage this emerging technology. The possession of a flexible communications means that readily adapts to virtual training will enhance planning and mission rehearsals tremendously.
Social implications
Interaction, perception, cognition and visualization based multimodal communication system is yet missing. Options to communicate, express and convey information in HMT setting with multiple options, suggestions and recommendations will certainly enhance military communication, strength, engagement, security, cognition, perception as well as the ability to act confidently for a successful mission.
Originality/value
The objective is to develop a multimodal autonomous interactive robot for military communications. This survey reports the state of the art, what exists and what is missing, what can be done and possibilities of extension that support the military in maintaining effective communication using multimodalities. There are some separate ongoing progresses, such as in machine-enabled speech, image recognition, tracking, visualizations for situational awareness, and virtual environments. At this time, there is no integrated approach for multimodal human robot interaction that proposes a flexible and agile communication. The report briefly introduces the research proposal about multimodal interactive robot in military communication.

Abstract
INTERNATIONAL discussion of the relationship that enables technology to be matched to training requirements was generated and encouraged at a recent conference organised by the Royal Aeronautical Society. Attended by civil and military representatives from a wide range of companies and authorities, a number of issues were addressed that encompassed various kinds of training systems and the advancing techniques that are being employed.

Abstract
Purpose
A narrative review of existing research literature was conducted to identify practices that are likely to improve the quality of de-escalation and use-of-force training for police officers.
Design/methodology/approach
Previous reviews of de-escalation and use-of-force training literature were examined to identify promising training practices, and more targeted literature searches of various databases were undertaken to learn more about the potential impact of each practice on a trainee's ability to learn, retain, and transfer their training. Semi-structured interviews with five subject matter experts were also conducted to assess the degree to which they believed the identified practices were relevant to de-escalation and use-of-force training, and would enhance the quality of such training.
Findings
Twenty practices emerged from the literature search. Each was deemed relevant and useful by the subject matter experts. These could be mapped on to four elements of training: (1) commitment to training (e.g. securing organizational support for training), (2) development of training (e.g. aligning training formats with learning objectives), (3) implementation of training (e.g. providing effective corrective feedback) and (4) evaluation and ongoing assessment of training (e.g. using multifaceted evaluation tools to monitor and modify training as necessary).
Originality/value
This review of training practices that may be relevant to de-escalation and use-of-force training is the broadest one conducted to date. The review should prompt more organized attempts to quantify the effectiveness of the training practices (e.g. through meta-analyses), and encourage more focused testing in a police training environment to determine their impact.

Abstract
Purpose
The paper aims to explain the limitations of existing cognitive architectures and affective models, and propose a new cognitive-affective architecture that can be integrated in real intelligent agents to make them more realistic and believable.
Design/methodology/approach
The paper evaluates the state of the art, and describes the design and implementation of the cognitive-affective architecture in an agent. A brief evaluation of the agent is provided.
Findings
The paper clearly states that it is possible to use cognitive architectures to help, but there is a lack of architectures that address the problem of combining cognition and emotion in agents in a unified, simplified way. A cognitive-affective architecture is useful to make believable intelligent agents in an easier way.
Research limitations/implications
The paper does not explore a lot of possible future work that can be done to extend the emotional expressions of the agent, as well as including direct emotional-sensing capabilities in real time.
Practical implications
The paper argues about the need to include cognitive-affective architectures in modern intelligent agents. The architecture allows to influence and modify the behavior of the agent in real time, to achieve a more realistic and believable interaction with the user.
Social implications
The paper remarks the importance of a cognitive-affective architecture that makes intelligent agents able to help the users in different tasks and environments.
Originality/value
The paper describes a new cognitive-affective architecture and its utility for modern intelligent agents. This is proven by including it in a previous agent, which boosts its behavior and emotional expression possibilities and thus improves user experience.

Abstract
Purpose
Informal learning is seen as the most important way to acquire and develop the skills and competencies required for work. The Dutch Defence organisation (DDO) aims to use the opportunities for development of employees that informal learning offers better and is looking for suitable interventions. Four possible interventions to improve informal learning were developed, based on factors that influence informal learning. The purpose of this paper is to assess how Dutch Military personnel rate these interventions and to gather their opinions and preferences per intervention.
Design/methodology/approach
A total of 96 employees completed an online mixed-method vignette study. In the questionnaire, the four interventions were introduced by a visualisation in the form of a “comic strip” (vignette), and respondents’ perceptions were measured with multiple choice and open-ended questions.
Findings
Respondents clearly indicated a preference for two of the four interventions, i.e. informal mentorship and safe learning environment. They provided numerous advantages and disadvantages per intervention. They also indicated that all four interventions could be used throughout the entire Dutch Defence Organisation.
Research limitations/implications
The results contribute to a thoughtful design of interventions that can be used in practice; also, the interventions can be improved based on the advantages, disadvantages and suggestions formulated by the respondents in this vignette study.
Originality/value
The designs of interventions are studied in a systematic way by the target population before they are actually developed and implemented. In addition, the use of “comic strips” and visualisations in vignette studies is quite original.

Abstract
Purpose
The purpose of this paper is to explain how intellectual capital (IC) is enacted and used in non‐profit symphony orchestras from an organisational behaviour perspective.
Design/methodology/approach
The paper is a nine‐month case study on two community‐based non‐profit orchestras. The method uses field observations, interviews, factor analysis, and visual models in explaining how IC is connected to organisational practices.
Findings
IC is perhaps best understood in its context to specific organisations rather than as discrete items that are allocated.
Research limitations/implications
The case study is limited to non‐profit orchestras based on an organisational behaviour perspective. The results, however, invite further research into how IC is used as a resource towards strategic planning.
Practical implications
The study results point towards managing IC resources, given that they are grounded in actions and practices of the organisation. Questions of “how” (how is IC used?) drive the study versus questions of “what” (identification of IC).
Originality/value
Understanding IC as context‐dependent provides management guidance to NPO orchestras for improving volunteer participation, motivation, and meeting personal goals. It also informs boards of possible outcomes in implementing organisational change.
