    No full text
    Motivation – to explore the applicability of a Human Factors methodology for the investigation of fratricide. Research approach – The EAST methodology was used to analyse an incident of fratricide and its ability to explore the Famous Five of Fratricide (F3) model was investigated. Findings/Design – the analysis revealed that EAST was able to provide explicit discussion of the Famous Five of Fratricide (F3) models five causal factors of communication, cooperation, coordination, schemata and situation awareness. Research limitations/Implications – the research explored a single case study and as such is couched at the initial phases of investigation. Originality/Value – the analysis provides a contribution to the knowledge urrounding fratricide both with respect to the novel application of the EAST methodology to an incident of fratricide, and also the causal factors identified by EAST within the fratricide incident. Take away message – the EAST methodology provides an innovative way of exploring causality in incidents of fratricide<br/

    Great expectations: a thematic analysis of situation awareness in fratricide

    This paper explores the role of Situation Awareness (SA) in accidents within the military domain, specifically in Close Air Support (CAS) missions. Several major examples of military fratricide (friendly fire) have arisen in such scenarios, and from the experience gained so far it is clear that poor SA has played a critical role. The study reported in this paper took place in a networked training facility, and two teams of army and air force personnel performed simulated CAS missions. One team performed in an effective manner, while the other team committed an error. Communications data from these two teams was subject to an analysis that enabled information networks to be created, which in turn provided a novel representation of systemic SA. The results demonstrated that SA differed in several critical and specific ways between the more effective and less effective teams. Of particular interest is that ‘better’ SA was found to be not merely ‘more’ SA, but more SA of appropriate stimuli. Linked to this is the finding that more communications do not necessarily support improvements in SA. Indeed, in this case fewer communications events were implicated in better team performance and SA. The findings confirm the importance of SA to safety within the military domain, but with several important and sophisticated caveats. The paper also contributes recommendations for improving SA in these environments, and a novel method for its measurement in challenging military contexts

    Combining social network analysis and the NATO Approach Space to define agility. Topic 2: networks and networking

    No full text
    This paper takes the NATO SAS-050 Approach Space, a widely accepted model of command and control, and gives each of its primary axes a quantitative measure using social network analysis. This means that the actual point in the approach space adopted by real-life command and control organizations can be plotted along with the way in which that point varies over time and function. Part 1 of the paper presents the rationale behind this innovation and how it was subject to verification using theoretical data. Part 2 shows how the enhanced approach space was put to use in the context of a large scale military command post exercise. Agility is represented by the number of distinct areas in the approach space that the organization was able to occupy and there was a marked disparity between where the organization thought it should be and where it actually was, furthermore, agility varied across function. The humans in this particular scenario bestowed upon the organization the levels of agility that were observed, thus the findings are properly considered from a socio-technical perspective

    Challenges for digitisation – learning from analogue mission planning teams

    No full text
    This paper aims to consider the conventional, analogue, mission planning process with the objective of identifying the decision making constraints and challenges for digitisation. Prototypes of digital mission planning systems are beginning to be devised and demonstrated, but there has been concern expressed over the design of such systems which fail to understand and incorporate the human aspects of socio-technical systems design. Previous research has identified many of the potential pitfalls of failing to take Human Factors considerations into account as well as the multiplicity of constraints acting on the planners and planning process. An analysis of mission planning in a Battle Group is presented, based on an observational study by the authors. This study illustrates the efficiency of an analogue process which has evolved over many generations to form the Combat Estimate, a process that is mirrored by forces throughout the world. The challenges for digitisation include ensuring that the mission planning process remains easy and involving, preserving the public nature of the products, encouraging the collaboration and cooperation of the planners, and maintaining the flexibility, adaptability and speed of the analogue planning process. It is argued that digitisation should not become an additional constraint on mission planning

    The famous five factors in teamwork: a case study of fratricide

    No full text
    The purpose of this paper is to propose foundations for a theory of errors in teamwork based upon analysis of a case study of fratricide alongside a review of the existing literature. This approach may help to promote a better understanding of interactions within complex systems and help in the formulation of hypotheses and predictions concerning errors in teamwork, particularly incidents of fratricide. It is proposed that a fusion of concepts drawn from error models, with common causal categories taken from teamwork models, could allow for an in-depth exploration of incidents of fratricide. It is argued that such a model has the potential to explore the core causal categories identified as present in an incident of fratricide. This view marks fratricide as a process of errors occurring throughout the military system as a whole, particularly due to problems in teamwork within this complex system. Implications of this viewpoint for the development of a new theory of fratricide are offered. <br/

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Decisions, decisions….and even more decisions: the impact of digitisation in the land warfare domain

    No full text
    Motivation - Digitised mission support systems are currently being introduced in the military arena. The projected benefits include quicker, better-informed, more efficient decision making by the teams using them; however, these claims are often made without appropriate scientific testing. Research approach – A live operational field trial of a new land warfare digital mission support system was observed. A range of Human Factors approaches were used to evaluate performance with the system in question. Findings/Design – As a corollary of various flaws associated with the digital system, decision making was found to be more difficult, more drawn out and more susceptible to error. Rather than augment the decision making process, in some cases these flaws were seen to create further decision making requirements for users. Research limitations/Implications – Using technology to provide access to more information alone does not guarantee improved decision making; designers must also consider aspects such as interface design, system usability and technological limitations in order to produce systems that truly support decision making in complex systems. Originality/Value – Typically, digital mission support systems are bereft of human factors analysis; this article provides insight and guidance for future system design efforts. Take away message – Inappropriately designed technology has the potential to degrade decision making; designers need to understand and carefully consider the existing decision making processes that the end system is being designed to support<br/

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
