    Fratricide: defective decision making

    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/

    Phase space shifts in command structures in networked systems

    This paper presents the rationale behind an important enhancement to the NATO SAS-050 approach space, combined with empirical results which take advantage of these enhancements. In Part 1 a new theoretical legacy for the NATO model is presented. This legacy inspires a number of developments which allow live data to be plotted into it, and we demonstrate that the model is well able to discriminate between alternative C2 structures. Part 2 illustrates this feature with multinational data from the ELICIT community. It is surprising to see that teams in both C2 and Edge conditions operate in broadly the same area of the phase space cube. The structure of the pre-ordained ELICIT ‘classic C2’ hierarchy and the deterministic nature of the shared task are put forward as explanations for this, and as future enhancements to the ELICIT paradigm

    Reduction of azo dyes is presented as a method for the synthesis of 2-amino phenol-4-oulfenic acid. The synthesis and reduction of some azo derivatives of 2-amino phenol-4-sulfonic acid are described. Preparation of the diazonium compounds of aniline, vitro aniline, 1-amino-2-nanhthol, 1-amino-2-naphthol-1-sulfonic acid, 2-amino phenol-4-sulfonic acid, 1-naphthol 1-amino, and 2-naphthylamine is discussed and their ability to couple with phenol-4-sulfonic acid evaluated. Reduction of the resultant azo dyes is discussed with reference to fission and the benzidine rearrangement. An overall presentation of results is Given in Tables I, II, and III on pages 27 - 29

    Servitisation and value co-production in the UK music industry

    Since the rise of music on the internet, record companies have reported falling sales of physical products. This has occurred at a time when technology has radically increased choice, availability and the opportunity for the consumer to purchase music. As the music industry has moved from a product to a service business model, has the loss of sales meant they have not taken their customers with them? This paper provides a description of different music consumers based upon quantitative analysis of consumer characteristics. The paper then undertakes an exploration of the relationship between the consumer groups and their purchasing preference in relation to intangible ‘service’ purchase such as downloaded music and the purchase of a tangible physical product such as CDs or vinyl. In addition, we analyse the relationship between consumer types and their propensity to actively engage with music communities, such as through engagement with social media, and thus their willingness to coproduce greater value. Finally we explore the moderating effects of age and time devoted to listening to music on purchasing preferences and music discovery

    Riyadh Transportation History and Developing Vision

    Get PDF
    AbstractRiyadh is the capital city of the Kingdom of Saudi Arabia. It is both a rapidly moving microcosm of worldwide trends in transportation, and a unique case study. The aim of this study is to investigate the reasons behind rising car ownership and its impact on public transportation. This paper charts the historical development of the city and presents the key factors that have shaped the transport network, including governmental motivation, urban planning and financial and demographic aspects. The study reviewed the history of the Riyadh transportation system and either component during the last five decades and the factors that have made Riyadh's situation unique. From oasis to Metropolis there are many pressing issues. Resolving these requires much more than narrow technical solutions. Instead, consideration of a much broader range of factors is needed. Riyadh is presented as a city case study and the key challenges are illuminated

    Notes On Some Common Misconceptions In Input-Output Impact Methodology

    Get PDF
    The methodology in many studies involving input-output analysis appears to be often misunderstood, particularly in the way multipliers are used. The preoccupation with multipliers has led in many cases to incorrect analytical procedures; for example, there is a temptation to first derive a multiplier and then use this multiplier to calculate the total impact on the economy. This paper demonstrates that this approach is often erroneous and can result in significant errors. In addition, the importance of determining how imports are treated when using input-output in empirical situations is discussed. This is particularly relevant when using input-output tables in developing countries. Other issues which are clarified include the use of output multipliers, state versus regional multipliers and impacts, expenditure switching and table balancing
