Supply chain risk management research agenda – from a literature review to a call for future research directions
No full textPurpose: Supply chain risk has increasingly attracted academic and corporate interest, however the supply chain risk debate in academic literature are rather limited to case and location specific studies. Hence, this paper utilised a systematic literature review to explore the supply chain risk research trends and gaps within the management literature.
Design/methodology/approach: To achieve the research objective a systematic literature review (SLR), looking into 25 years since 1990, into supply chain risk management was conducted, which resulted in 114 papers.
Findings: While the supply chain risk management literature is growing, results from the systematic literature review identified limited organized understanding of what constitutes holistic supply chain risk process, and high reliance of particular categories for supply chain risk, such as the high reliance on specific country settings (the USA and the UK); limited presence of cross competitive supply chain risk process analysis and challenges in developing conceptual supply chain risk frameworks.
Research limitations/implications: The supply chain risk embeds categories of location, scope of supply chain, risk management tools and industry sectors involved, The search for related publications was mainly used from a wide range of coverage from accountancy to design in supply chain risk, hence although there is indication to specific industries, and foci of risk, this could be further explored.
Practical implications: This review of supply chain risk management identifies various research gaps and directions for future research to develop theory and practical understanding of supply chain risk.
Originality/value: Current literature on supply chain risk have been assessed based on its definition and utilisation. The current paper bridges this gap by synthesizing the diverse academic journal papers into the categories based on design continiuum, relationship continiuum, process continiuum and economic continiuum. In addition it highlighted the gaps in industry context, theoretical contribution, geographic location, and research methods applied and addresses the scope for further research
Planning and controlling design in engineered-to-order prefabricated building systems
Full text linkPurpose – The purpose of this paper is to propose a model for planning and controlling the design process in companies that design, manufacture and assemble prefabricated engineer-to-order (ETO) building systems. This model was devised as an adaptation of the Last Planner® System for ETO multiple-project environments.
Design/methodology/approach – Design science research, also known as prescriptive research, was the methodological approach adopted in this research. An empirical study was carried out at the design department of a leading steel fabricator from Brazil, in which the proposed model was implemented in six different design teams.
Findings – The main benefits of the proposed model were shielding design work from variability, encouraging collaborative planning, creating opportunities for learning, increasing process transparency, and
flexibility according to project status. Two main factors affected the effectiveness of the implementation process commitment and leadership of design managers, and training on design management and project planning and control core concepts and practices.
Research limitations/implications – Some limitations were identified in the implementation process:
similarly to some previous studies (Ballard, 2002; Codinhoto and Formoso, 2005), the success of constraint analysis was still limited; some of the metrics produced (e.g. ABI, causes of planning failures) have not been fully used for process improvement; and systematic feedback about project status was not properly implemented and tested.
Originality/value – The main contributions of this study in relation to traditional design planning and control practices are related to the use of two levels of look-ahead planning, the introduction of a decoupling point between conceptual and detail design, the proposition of new metrics for the Last Planner® System, and understanding the potential role of visual management to support planning and control
A robust detector for rolling element bearing condition monitoring based on the modulation signal bispectrum and its performance evaluation against the Kurtogram
Full text linkEnvelope analysis is a widely used method for rolling element bearing fault detection. To obtain high detection accuracy, it is critical to determine an optimal frequency narrowband for the envelope demodulation. However, many of the schemes which are used for the narrowband selection, such as the Kurtogram, can produce poor detection results because they are sensitive to random noise and aperiodic impulses which normally occur in practical applications. To achieve the purposes of denoising and frequency band optimisation, this paper proposes a novel modulation signal bispectrum (MSB) based robust detector for bearing fault detection. Because of its inherent noise suppression capability, the MSB allows effective suppression of both stationary random noise and discrete aperiodic noise. The high magnitude features that result from the use of the MSB also enhance the modulation effects of a bearing fault and can be used to provide optimal frequency bands for fault detection. The Kurtogram is generally accepted as a powerful means of selecting the most appropriate frequency band for envelope analysis, and as such it has been used as the benchmark comparator for performance evaluation in this paper. Both simulated and experimental data analysis results show that the proposed method produces more accurate and robust detection results than Kurtogram based approaches for common bearing faults under a range of representative scenarios

Ethical Engagement, Embedded Reflection, and Mutual Empowerment in the Clinical Process
No full textThe Legal Advice Clinic at Huddersfield is now operational. It is located permanently in town centre shop premises in the heart of the local community. In this chapter we will explain theoretically and with qualitative evidence how our social justice design for clinical education at Huddersfield seeks to embed reflective activity into each stage of procedure and protocol of the advice process. This strategy avoids the documented deficiencies of a ‘bolted on’ approach to reflective practice, namely, the ephemeral conscious influence of reflection on the practitioner, and more importantly, the lack of a substantive ethical context and direction for reflection that is the sine qua non of autonomy
Song in space and space in song: physical and conceptual boundaries in English devotional music, 1250–1500
No full textThis essay highlights the permeability of the walls that bounded devotional music, and will identify the complexity of interactions between space and song. Just as physical spaces were designed to house song but could not fully contain it, so were musical genres and structures capable of reflecting and testing those spatial boundaries. In this chapter, I consider music in relation not only to the sacred architectural spaces designed for formal performance of liturgical song, but also (and more provocatively) the spacial metaphors of the body – simultaneously devotional song’s most ubiquitous subject and the performance vehicle for those ideas – and the gendered nature of texted song itself
