      Antony, J; Psomas, E; Garza-Reyes, J.A.; Hines, P; Heriot-Watt University, Edinburgh; University of Patras, Greece; University of Derby; Waterford Institute of Technology, Ireland (Taylor & Francis, 2020-06-29)
      Academic literature on Lean Manufacturing (LM) is widely available. However, due to its fragmentation, the contribution of LM from practical and academic perspectives is controversial. This paper establishes the practical implications of LM studies carried out worldwide and identifies novel research streams. A Systematic Literature Review (SLR) of peer-reviewed journal articles was conducted. A total of 401 articles published in 61 journals during 2010-2019 were collected from four major management science publishers. An “affinity diagram” was applied to organize the data into natural and logical themes. Conceptual frameworks concerning LM practical implications and future research agenda were formulated. Meaningful themes of LM practical implications and future research suggestions were revealed and classified into two categories. In category one pertaining to the internal nature of LM, themes related to the pre-implementation, implementation and post-implementation phases of LM were identified. In category two pertaining to the external nature of LM, themes related to the country in which the companies operate, the diverse managerial systems available, and the methodological research approach were identified. The main themes supported in the literature by most references were determined. Finally, respective statements concerning the practical implications of LM and the future research agenda are analytically presented.

      Conway, Chris; Chamberlain, Katy J.; Harigane, Yumiko; Morgan, Daniel; Wilson, Colin; Research Institute of Earthquake and Volcano Geology, Japan; National Museum of Nature and Science, Japan; University of Derby; University of Leeds; Victoria University of Wellington (The Geological Society of America, 2020-06-25)
      Studies of pre-eruptive processes at active volcanoes require precise petrochronological constraints if they are to contribute to hazard assessment during future eruption events. We present petrological and geochemical data, and orthopyroxene diffusion timescales for samples from late Pleistocene high-Mg andesite dacite lavas (Mg#53–69) at Ruapehu volcano, New Zealand, as a case study of rapid magma genesis and eruption at a continental arc stratovolcano. Assembly of Ruapehu high-Mg magmas involved the mixing of primitive magmas plus entrained mantle equilibrated olivines with mid-crustal felsic mush bodies, yielding hybridized magmas with ubiquitous pyroxene reverse-zoning patterns. Orthopyroxene Fe-Mg interdiffusion timescales linked to quantitative crystal orientation data show that most lavas erupted <10 days after resumption of crystal growth following magma mixing events. The eruption of lavas within days of mixing events implies that pre-eruptive warnings may be correspondingly short.
    • Monetary policy and commodity markets: unconventional versus conventional impact and the role of economic uncertainty

      Apergis, Nicholas; Chatzianoniou, Ioannis; Cooray, Arusha; University of Derby; University of Portsmouth; Embassy of Sri Lanka in Oslo; Centre for Poverty Analysis, Sri Lanka (Elsevier, 2020-06-20)
      This study explores the impact of both conventional and unconventional monetary policies in the US and the Euro area on the mean and volatility of certain commodity prices. The analysis considers the prices of eight commodities, i.e. oil, natural gas, gold, silver, aluminium, copper, platinum, and nickel, while the methodology employs the EGARCH-X modelling approach. The empirical findings clearly document that (i) the direction of the impact of both conventional and unconventional monetary policy on commodity returns and commodity volatility is similar and (ii) the impact from unconventional monetary policy on both commodity returns and volatility is relatively more pronounced, while these findings hold valid, irrespective of the geographical region and commodity type. Further investigation of the disparity on the size of the impact through the prism of economic uncertainty reveals that unconventional monetary policy has a stronger effect on economic uncertainty, thereby offering an indirect channel of monetary policy transmission on commodity markets.
    • Convergence of per capita carbon dioxide emissions among developing countries: evidence from stochastic and club convergence tests

      Apergis, Nicholas; Payne, James; University of Derby; University of Texas, El Paso (Springer, 2020-06-19)
      This exploratory study extends the literature on the convergence of per capita carbon dioxide emissions in analyzing the stochastic and club convergence within a panel framework for developing countries. The results from Pesaran (2007) and Bai and Carrion-i-Silvestre (2009) panel unit root tests with allowance for cross-sectional dependence confirm stochastic convergence for low-income, lower-middle income, and combined country panels. Further analysis using the nonlinear time-varying factor model of Phillips and Sul (2007; 2009) to test for convergence reveals the emergence of multiple convergence clubs within each of the three country panels examined. We observe geographic proximity among many of the countries within the respective convergence clubs.
    • Can the Covid-19 pandemic and oil prices drive the US partisan conflict index?

      Apergis, Nicholas; Apergis, Emmanuel; University of Derby; University of Huddersfield (Asia-Pacific Applied Economics Association, 2020-05-29)
      This paper investigates the effect of the Covid-19 and oil prices on the US partisan conflict. Using daily data on world Covid-19 and oil prices, monthly data on the US Partisan Conflict index, January 21 to April 30, 2020, and the MIDAS method, the findings document that both Covid-19 and oil prices mitigate US political polarization. The findings imply that political leaders aim low for partisan gains during stressful times.
    • The emerging evidence of a time through the emergence of an image through time: a correlation between the early photographic imaging processes anthotypes and natural dyes

      Wells, Kate; Jackson, Jane; Pearson, Emily; University of Derby (2015-03)
      This paper discusses the correlation of Natural dyes with the 19th Century photographic processes ‘Anthotypes’. Exploring the connection between natural dyes and their fastness properties in relation to the success of this early photographic imaging process: The emerging evidence of imagery on exposure to light as the colorants change with time either physically due to fading or heat and moisture. This project plans to document through Alternative photography, Archival evidence of an English Estate’s Garden (the traces that remain), Cotesbach Hall and the Marriot Family Archive from the late 19th and early 20th Centuries through collaborative research between different disciplines: historical archive and 19th Century English horticulture with natural dye colouration and ‘Anthotypes’ a early photographic processes of that period. By exploring the natural plant extractions of Cotesbach Hall Gardens with investigations and experimentation into ‘Anthotypes’ the aim of which, is to understand the symbiotic relationship that the natural colorant (Dye) has with the success or failure of this type of photographic process, the emerging evidence of a time through the emergence of an image through time: Positive exposure over hours/days/weeks. The main objective of the research is to employ archival research and past and current photographic images within a scientific technical methodology normally applied to textile coloration as to Why and How Anthotypes work? Their correlation both colorant and positive have with sunlight, artificial daylight and ultra violet light in relation to quality and colour of images achieved on exposure, with the fastness properties natural dyes /plant extracts employed within the process. The initial literature research undertaken was into the three completely different scientific areas that were being investigated during the 19th Century: English Garden Horticulture, Textile colouration via natural dyes and the success or failure of early photographic experiments using plant juices known as ‘Anthotypes’ developed by Sir John Herschel in 1842. Synthetic dyes had not been discovered or were employed within the Textile Industry until 1856 with the discovery of ‘Perkins purple’ or ‘Mauveine’ by William Henry Perkin. This was followed by a practical investigation into the relationship natural colours obtained from plants and vegetables within the gardens of Cotesbach Hall had with their fastness or fugitive properties in enabling the creation of a successful positive images using with the early photographic technique of the period, known as Anthotypes. The resulting imagery documenting: ‘The Emerging Evidence of a Time through the Emergence of an Image through Time’ A correlation between the early photographic imaging processes Anthotypes and Natural Dyes’.
    • The potential of fatty acid isotopes to trace trophic transfer in aquatic food-webs

      Burian, Alfred; Nielsen, Jens M.; Hansen, Thomas; Bermudez, Rafael; Winder, Monika; University of Derby; Stockholm University; Helmholtz Centre for Ocean Research Kiel (GEOMAR), Kiel, Germany; Escuela Superior Politécnica del Litoral, ESPOL, Guayaquil, Ecuador (The Royal Society, 2020-06-15)
      Compound-specific isotope analyses (CSIA) of fatty acids (FA) constitute a promising tool for tracing energy flows in food-webs. However, past applications of FA-specific carbon isotope analyses have been restricted to a relatively coarse food-source separation and mainly quantified dietary contributions from different habitats. Our aim was to evaluate the potential of FA-CSIA to provide high-resolution data on within-system energy flows using algae and zooplankton as model organisms. First, we investigated the power of FA-CSIA to distinguish among four different algae groups, namely cyanobacteria, chlorophytes, haptophytes and diatoms. We found substantial within-group variation but also demonstrated that δ13C of several FA (e.g. 18:3ω3 or 18:4ω3) differed among taxa, resulting in group-specific isotopic fingerprints. Second, we assessed changes in FA isotope ratios with trophic transfer. Isotope fractionation was highly variable in daphnids and rotifers exposed to different food sources. Only δ13C of nutritionally valuable poly-unsaturated FA remained relatively constant, highlighting their potential as dietary tracers. The variability in fractionation was partly driven by the identity of food sources. Such systematic effects likely reflect the impact of dietary quality on consumers' metabolism and suggest that FA isotopes could be useful nutritional indicators in the field. Overall, our results reveal that the variability of FA isotope ratios provides a substantial challenge, but that FA-CSIA nevertheless have several promising applications in food-web ecology. This article is part of the theme issue ‘The next horizons for lipids as ‘trophic biomarkers’: evidence and significance of consumer modification of dietary fatty acids’.
    • How selection of collaborating partners impact on the green performance of global businesses? An empirical study of green sustainability

      Ramanathan, U., Mazolla, E., Mohan, U., Bruccoleri, M., Awasthi, A., Garza-Reyes, J.A.; University of Derby (Taylor & Francis, 2020)
      In recent days, both collaboration and sustainability have become an integral part of many global supply chains to achieve business excellence. Although previous literature and actual practices confirmed the successful implementation of sustainability practices through supply chain collaborations, it is not clear how collaborating partners can support financial and environmental performance, and hence strengthen the partnership performance in the global supply chains. To address this practice-based research question, we test the theoretical underpinning of suppliers and logistics partners in relation to required skills selection. We capture the depth of interdependencies in collaborations for routine operations and sustainability, through empirical evidence. We used case study observations from three global companies to develop a conceptual model and also conducted a questionnaire survey to test the conceptual model. The results of case analysis confirmed two dimensions of collaborations that could strengthen relationship; namely, partners’ selection and sustainability team formation. Data analysis strongly support business collaborations having careful choice of supply chain partners and logistics operators who are ready to maintain green operations with transparent information sharing. Results of this study also inform managers about the importance of commitment from collaborating partners to achieve sustainability in their global supply chains. It is clear from the results that both the business and financial performances will be strengthened by environmental positioning (green objectives) of the companies.
    • The neurophysiological relationship between number anxiety and the EEG gamma-band

      Baker, Ian; University of Derby (Taylor and Francis, 2020-06-11)
      The development of math anxiety is thought to originate at a young age, as a form of number anxiety, but has not been investigated extensively. Research has shown greater levels of EEG gamma-band activity are experienced during threat perception and attentional bias. This has been identified in high math anxious individuals when confronted with math-based tasks, but has not yet been explored for number anxiety specifically. Single-digit numbers and letters were presented to 15 high and 15 low math anxious participants, who were required to observe the stimuli. High math anxious participants displayed significantly greater levels of gamma activity during number observation compared to letter observation. Findings suggest high math anxious individuals may have a threat-related response to observation of simple numerical stimuli. Further behavioural investigations are needed, but high math anxious individuals may display avoidance towards number and math due to a threat response associated with increased gamma activity.
    • An MCDA cause-effect factors model for the implementation of Greenstone digital library soft-ware

      Rathee, S; Kumar, A; Kaushik, S; Kazimieras Zavadskas, E; Banaitis, A; Garza-Reyes, J.A.; Ganga Institute of Management and Technology, Haryana, India; University of Derby; PDM University, Bahadurgarh, India; Vilnius Gediminas Technical University, Vilnius, Lithuania (Emerald, 2020-06-16)
      The selection of an effective library software plays an important role not only for students, academic staff, and the library staff but it also helps an institution by having the library management system more centralized. Therefore, the aim of this study is to develop a Multiple- Criteria Decision Analysis (MCDA) cause and effect factor model for the implementation of the Greenstone digital library (GSDL) software. A thorough review of the literature is conducted to develop an initial list of the appropriate evaluation factors that play a significant role in the implementation of GSDL software. The data was collected from a domain of experts in the library sciences field. A combined approach of Delphi-DEMATEL methods is employed for the definition of these factors and to construct an MCDA cause-effect model which represent their relationships. The DEMATEL analysis resulted in the division of all factors into two groups, i.e., causes and effects. The results show that content management, having a user-friendly interface and usability, information search and retrieval, authentication and authorization fall into the cause group. These factors directly affect the remaining factors. Content acquisition, classification, access, control and privacy management, plus metadata submission and support fall into the effect group. The research findings can help library professionals to make effective decisions to facilitate the successful implementation of GSDL software in a library and the enhancement of library technology. The results of this study can be useful for library professionals and decision-makers to select the most appropriate software for the implementation of library technology. The study analysis shows that for GSDL, having a user-friendly interface and usability, information search and retrieval plus authentication, and authorization factors have seven positive relationships with other factors. Secondly, content management and classification have six relationships with other factors. Thirdly, access control plus privacy and management have two relationships. Content acquisition has only one relationship with other factors. It is recommended that the user-friendly interface and usability, information search and retrieval, as well as authentication and authorization should be the initial areas of focus if GSDL is to be implemented successfully in digital libraries. The proposed MCDA cause-effect model can be useful for library professionals or decision-makers in the context of selecting software to be implemented in a library and to minimize implementation costs.
    • Digital-based self-management interventions for people with osteoarthritis: Systematic review with meta-analysis

      Safari, Reza; Jackson, Jessica; Sheffield, David; University of Derby (JMIR Publications Inc., 2020-06)
      Osteoarthritis (OA) is not curable but the symptoms can be managed through Self-management programmes. Due to the growing burden of arthritis to the health system, and the need to ensure high quality integrated services, delivering Self-management programmes through digital technologies could be an economic and effective community-based model of care. To analyze the effectiveness of digital-based self-management programs on patient outcomes in people with OA. Seven online databases and three grey literature databases were searched for randomized controlled trials (RCT) assessing digital-based structured self-management programs (D-SMP) on self-reported outcomes including pain, function, disability, and health-related quality of life in people with OA. Two reviewers independently screened the search results and reference list of identified papers and related reviews. Data about the intervention components and delivery, and behavioral change techniques were extracted. Meta-analysis, risk of bias sensitivity analysis and subgroup analysis were performed where appropriate. The GRADE approach was used to assess the quality of evidence. Eight studies were eligible including 2687 people with OA. Self-management programs were delivered via telephone plus audio/video, internet or mobile app. D-SMP compared to Treatment As Usual control group resulted in a significant, homogeneous, moderate reduction in pain (SMD -0.28, 95% CI -0.38 to -0.18) and improvement in physical function (-0.26 95% CI -0.35 to -0.16) at post-treatment. The D-SMP effect reduced slightly at 12 months follow-up but remained significant and moderate. Using the GRADE approach, the quality of evidence was rated as ‘moderate’. D-SMPs may result in a moderate improvement in pain symptoms and function in people with OA delivered. Further research is required to confirm the findings of the review and assess the effects of D-SMPs on other health-related outcomes. Clinical Trial: PROSPERO: CRD42018089322
    • Découverte de l’artiste’ (discovering the artist): Finding Marion Adnams through her work with a focus on ‘Infante égarée

      Forde, Teresa; University of Derby (2018)
      This video installation expresses the process of research Marion Adnams' paintings and the paper model of Infante égarée in particular. A version of paper model from the original painting has been constructed and animated in order to understand the structure of the original paper doll and to emulate the movement that is implicit in its structure. The animation was then superimposed onto the original painting. Adnams described the figure as lost and wandering in the forest and this sense of dislocation is captured within the twisting movement of the figure and haunting soundtrack. The title of the painting is also restored to Adnams’ preferred French title. The video is part of the Marion Adnams Project and illustrates an interest in practice as a form of research. The video installation formed part of the ‘Marion Adnams: A Singular Woman’ retrospective at Derby Museums and Gallery (Dec 2017-March 2018).
    • The role and impact of executive coaching in the Maltese public sector

      Borg Ellul, Duncan; Wond, Tracey; University of Derby (Emerald, 2020-04-06)
      The present study aims to conduct a critical review of an existing set of practices within the Maltese public sector. This study is based on interpretivism (people-centred approach) embedded in a pragmatic research paradigm (the use of mixed methods). Misconceptions about the role and practice of executive coaching in Malta relates to the similar roles ascribed to mentoring, supervision, therapy, consultation, coaching, audit and watchdog under the misnomer of “coaching”. The main contribution of this research is to the community of professional practitioners as well as to the Maltese central government to improve managerial effectiveness in the Maltese public sector with several endorsed policy-level recommendations presented in the study. The results suggest a restructuring of a well-defined, structures, systems and dynamics within the Maltese public administration, the ability by senior management including senior public officers (SPOs) to recognise high-potential talents, the need to expand leadership capacity, the establishment of a professional coaching body and a national coaching network framework. To the best of the authors’ knowledge, this is the first study that investigates the role and impact of executive coaching in the Maltese public sector using quantitative and qualitative empirical data.

    • PaintingDigitalPhotography conference

      Robinson, Carl; University of Derby (2017-05-09)
      The PaintingDigitalPhotography conference seeks to investigate how artists and theorists are currently engaged in critical discourses around the shifting relationships of painting, photography, and digital manipulation. How are these mediums being defined in their connection to one another as new hybrid forms are being created through their combination? What do these combinations tell us about these mediums and disciplines, their natures and practices, in the digital age? In what ways might digital imaging and manipulation enable a painting / photography interconnectivity? Central to the debate will be the focus on the blurred boundaries, common threads, antagonisms, distinctions, and growing interrelationship between painting, photography, and ‘the digital’ in the development of new creative practices.

    • The legacy of Mad Men: cultural history, intermediality and American television

      McNally, K; Marcellus, J; Forde, Teresa; Fairclough, K; London Metropolitan University; Middle Tennessee State University; University of Derby; University of Salford (Palgrave Macmillan, 2019-12-12)
      For seven seasons, viewers worldwide watched as ad man Don Draper moved from adultery to self-discovery, secretary Peggy Olson became a take-no-prisoners businesswoman, object-of-the-gaze Joan Holloway developed a feminist consciousness, executive Roger Sterling tripped on LSD, and smarmy Pete Campbell became a surprisingly nice guy. Mad Men defined a pivotal moment for television, earning an enduring place in the medium’s history. This edited collection examines the enduringly popular television series as Mad Men still captivates audiences and scholars in its nuanced depiction of a complex decade. This is the first book to offer an analysis of Mad Men in its entirety, exploring the cyclical and episodic structure of the long form series and investigating issues of representation, power and social change. The collection establishes the show’s legacy in televisual terms, and brings it up to date through an examination of its cultural importance in the Trump era. Aimed at scholars and interested general readers, the book illustrates the ways in which Mad Men has become a cultural marker for reflecting upon contemporary television and politics.

    • A decision-support framework for lean, agile and green practices in product life cycle stages

      Udokporo, Chinonso; Anosike, Anthony; Lim, Ming; University of Derby; Coventry University (Taylor & Francis, 2020-05-19)
      Improving operations performance is often achieved through the application of practices such as Lean, Agility and Green (LAG) practices. However, the wide choice of LAG practices available to address customer requirements can be challenging for those with limited knowledge of LAG practices and their efficacy. Therefore, this research provides a framework for selecting appropriate LAG practices that considers product life cycle (PLC) stages for more effective application of practices. The framework was developed following thorough literature review to capture LAG practices. These form the basis for decision making tools incorporated within the framework including an analytic hierarchy process (AHP), statistical inference and regression analysis, ensuring a systematic approach to the analysis and decision support. The framework was verified and validated through a Delphi study and case study respectively. This research makes a contribution to the body of knowledge by providing a framework which could serve as a guide for businesses in the fast moving consumer goods (FMCG) industry to systematically integrate and adopt LAG to better manage their processes and meet customer requirements.
