    • UK University staff experience high levels of sedentary behaviour during work and leisure time

      Faghy, Mark A; Roscoe, Clare MP; Pringle, Andy; Duncan, Mike; Buchanan Meharry, John; University of Derby; Coventry University (Taylor and Francis Online, 2021-01-11)
      Reducing sedentary behaviours at work is imperative. Before effective strategies can be developed there is a need to understand profiles of activity within particular roles and organisations. This study aimed to determine activity profiles of staff by job title at a UK University. Three-hundred and seventeen participants completed the short form International Physical Activity Questionnaire to determine physical activity profiles. Fifty-one participants also wore a wrist worn GENEActiv accelerometer for seven days and completed a self-report diary denoting work and leisure hours. Twenty-one per cent of respondents were categorised as inactive and achieved 298 ± 178 metabolic equivalent minutes per week (MET-min/week). Those in administrative roles were most sedentary (501 ± 161 minutes/day). Accelerometer data highlighted that sedentary time was identical between job roles (pooled mean 8746 ± 823 counts) and equated to 84 ± 9% of total time. During working hour’s management, professional and specialist job roles had the highest level of sedentary time (2066 ± 416 counts). Time spent undertaking sedentary activities during working hours contributes to reduced overall activity and can impede productivity, performance, and health. Interventions encouraging regular movement and preventing sedentary behaviours at work are therefore required.
    • When The Future Comes

      Locke, Caroline; University of Derby (Nottingham Contemporary, 2018-06-30)
      An afternoon of talks, artworks and a workshop that looked to the future as the environment and climate is changing. Featuring Dr John King, Senior Scientist at the British Antarctic Survey, artists Dr Rachel Jacobs, Caroline Locke, Frank Abbot, Juliet Robson, Wallace Heim, Matt Watkins, Dominic price, Horizon Digital Economy Research (University of Nottingham) and Prof Esther Eidinow, Professor of Ancient History (University of Bristol). The activities explored how we respond to climate change through a combination of art, science, technology and in our every day lives by presenting 'Performing the Future' an artist/research project led by Dr Rachel Jacobs. Caroline presented some of her current research and artistic practice in relation to science and climate change, including her Frequency of Trees, Significant Trees, association with The Woodland Trust and Smoke in the trees experiments with Jacobs and Watkins.
    • The Inclusion of a Matrix Metalloproteinase-9 Responsive Sequence in Self-assembled Peptide-based Brain-Targeting Nanoparticles Improves the Efficiency of Nanoparticles Crossing the Blood-Brain Barrier at Elevated MMP-9 Levels

      Islam, Yamir; Ehtezazi, Parinaz; Cashmore, Andrew; Marinsalda, Elena; Leach, Andrew G.; Coxon, Christopher R.; Fatokun, Amos A.; Sexton, Darren W.; Khan, Iftikhar; Downing, James; et al. (Elsevier BV, 2020-12-14)
      This study investigated whether the inclusion of a matrix metalloproteinase-9 (MMP-9) responsive sequence in self-assembled peptide-based brain-targeting nanoparticles (NPs) would enhance the blood-brain barrier (BBB) penetration when MMP-9 levels are elevated both in the brain and blood circulation. Brain-targeting peptides were conjugated at the N-terminus to MMP-9-responsive peptides, and these were conjugated at the N-terminus to lipid moiety (cholesteryl chloroformate or palmitic acid). Two constructs did not have MMP-9-responsive peptides. NPs were characterised for size, charge, critical micelle concentration, toxicity, blood compatibility, neural cell uptake, release profiles, and in vitro BBB permeability simulating normal or elevated MMP-9 levels. The inclusion of MMP-9-sensitive sequences did not improve the release of a model drug in the presence of active MMP-9 from NPs compared to distilled water. 19F NMR studies suggested the burial of MMP-9-sensitive sequences inside the NPs making them inaccessible to MMP-9. Only cholesterol-GGGCKAPETALC (responsive to MMP-9) NPs showed <5% haemolysis, <1 pg/mL release of IL-1β at 500 μg/mL from THP1 cells, with 70.75 ± 5.78% of NPs crossing the BBB at 24 h in presence of active MMP-9. In conclusion, brain-targeting NPs showed higher transport across the BBB model when MMP-9 levels were elevated and the brain-targeting ligand was responsive to MMP-9.
    • An old dog and new tricks: Genetic analysis of a Tudor dog recovered from the Mary Rose wreck.

      Zouganelis, George D; Ogden, Rob; Nahar, Niru; Runfola, Valeria; Bonab, Maziar; Ardalan, Arman; Radford, David; Barnett, Ross; Larson, Greger; Hildred, Alex; et al. (Elsevier, 2014-10-14)
      The Tudor warship the Mary Rose sank in the Solent waters between Portsmouth and the Isle of Wight on the 19th of July 1545, whilst engaging a French invasion fleet. The ship was rediscovered in 1971 and between 1979 and 1982 the entire contents of the ship were excavated resulting in the recovery of over 25,000 objects, including the skeleton of a small to medium sized dog referred to as the Mary Rose Dog (MRD). Here we report the extraction and analysis of both mitochondrial and genomic DNA from a tooth of this animal. Our results show that the MRD was a young male of a terrier type most closely related to modern Jack Russell Terriers with a light to dark brown coat colour. Interestingly, given the antiquity of the sample, the dog was heterozygotic for the SLC2A9 gene variant that leads to hyperuricosuria when found in modern homozygotic animals. These findings help shed light on a notable historical artefact from an important period in the development of modern dog breeds.
    • Anti-neutrophil cytoplasmic antibodies-associated vasculitis: a guide and case study

      Boyer, Helena; Mortimore, Gerri; Royal Derby Hospital; University of Derby (Mark Allen Group, 2020-12-10)
      Vasculitis is a relatively rare and poorly understood condition causing inflammation of the blood vessels, which in turn can affect a patient's respiratory and renal systems. In some cases, ocular involvement can cause loss of sight and hearing loss may also be a red flag for vasculitis, which, if not treated early, can cause complete hearing loss. Anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) is a group comprising granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis (EGP). AAV is fatal if untreated and as increased risk escalates with age, coupled with a decline in renal function, these are the principal predictors of poor outcome. Vital roles for nursing vasculitis patients lie in managing inflammation and pain, as these distressing symptoms are prevalent in the disease. Because of the multiple complications that can occur with vasculitis, treatment-related information is a high priority for these patients. As nurses are well placed to deliver information, value lies in their role in reducing the negative impacts on treatment regimens and compliance that accompany patients' poor insight into their condition.

The book will appeal to students, academics, photographic artists, curators, and those with an interest in art, photography, photographic history and theory. It includes black and white illustrations throughout, alongside a generous selection of colour plates, including portfolios by photographers Craig Easton, for the project SIXTEEN, and the works of industrial photographer Maurice Broomfield.
    • Small Sculpture Show

      Fisher, Craig; University of Derby (Village Green Arts & Music Festival presented by Metal, 2016-07-09)
      Fisher was invited by artist and curator Jonathan Kipps to participate in the, ‘Small Sculpture Show’ exhibition as part of Village Green Arts & Music Festival presented by Metal, Southend-on-Sea. Fisher was interested in the opportunity to present a singular sculpture from the ‘Homemade Device’ series amongst a range of other artists who were also presenting small works as this provided a different context of experiencing this series of works which would ordinarily be viewed as part of a group installation. The artists included in the exhibition were, Craig Fisher, Jonathan Kipps, Laura Keeble, Lauren O’Grady, Lauren Wilson & Teal Griffin The exhibition was curated by Jonathan Kipps
    • Things we didn’t have before

      Fisher, Craig; University of Derby (Pump House Gallery, 2015)
      For the exhibition, ‘things we didn’t have before’, Pump House Gallery transforms into a cabinet of curiosities. Each of the gallery’s floors serve as different compartments, a treasure trove of wondrous artworks and objects that await discovery. Supported by curator Hannah Conroy, local recovery group CDS Wandsworth have selected artworks and objects to form a new public collection that tells the unique and unexpected stories behind objects and their creators or collectors. Each year Pump House Gallery works with a different Wandsworth community-based group for its annual Open Call exhibition, with the aim of providing contemporary art experience, knowledge and practice through the development of a public exhibition. Over 100 arts practitioners and collectors submitted their unusual and intriguing objects and artworks for consideration. Over six sessions, the curatorial group made its final selection of pieces by 20 artists and collectors and determined how to present these within the Pump House Gallery setting. ‘things we didn’t have before’ is an exhibition that presents both a collection of objects and a collection of the stories that accompany them, and how these are read is unique to each gallery visitor. Fisher presented his ongoing series ‘Homemade Devices’ working with the curator to explore and reconsider the methodologies of display and staging for the works by showing the works on a specially constructed shelving unit within one of the central gallery spaces. Included artists; Terry Barber, Tom Buchanan, Maria L. Felixmüller, Craig Fisher, Matt Gee, Paolo Giardi, Greta Hauer, Kevin Hunt, Scott Joseph, Morwenna Lake, Mindy Lee, Sonia Levy, Jammie Nicholas, Marina Rees, Sue Ridge, Cyrus Shroff, Hazel Stone, Julia Zastava, Willow Rowlands, Yoke and Zoom. Fisher was invited by Pump House Gallery to contribute to an in-conversation event, ‘When an object becomes a thing’ on 5 December 2015 alongside artists, Lauren Godfrey, Greta Hauer and curator, Hannah Conroy. Using this ambiguous statement as a starting point, the event aims to delve deeper into conversation instigated by the exhibition itself: the point at which an object transcends its inanimate status and is imbued with significance beyond its immediate visual quality or utilitarian function.
    • Inter-firm knowledge transfer between strategic alliance partners: A way forward

      He, Qile; Ghobadian, Abby; Gallear, David; University of Derby; University of Reading; Brunel University London (Wiley, 2021-01-11)
      Strategic alliance (SA) is pursued by a diverse array of firms motivated by a range of factors. Among the SA themes, knowledge transfer (KT) has gained significant popularity over the past fifteen years. The developing literature is ontologically, epistemologically, and methodologically diverse. In spite of helpful reviews, the intellectual structure (up-stream decisions) of SA–KT research remains unclear, arguably resulting in the accidental rather than deliberate diversity potentially slowing the advancement of knowledge, its efficacy, its interpretation, and utility. By systematically analysing the intellectual structure of the empirical SA–KT studies published in peer-reviewed journals between 1990 and 2017 we address these shortcomings. The aim is to identify the preponderance of particular methods, and/or analytical procedures, developing the essence of the established research conventions. By reviewing the up-stream rather than the more conventional down-stream decisions, we offer an alternative approach to conducting systematic management literature reviews helpful to future researchers.
    • Gestures of Resistance

      Fisher, Craig; Wainwright, Jean; University of Derby (University for the Creative Arts, Canterbury Romantso Cultural Centre, Athens, Greece, 2017-04)
      Gestures of Resistance aims to respond to our current general mood of political anxiety and alienation by opening up socio-political critique in order to resist the palpable feeling of disempowerment. Rather than accepting the non-choice of the neoliberal setup of Greece or current right-wing politics both in America and Europe, the artists of Gestures of Resistance reflect on the current state of our political condition, our current housing situation, the state of education and art, liberalism, diversity and pluralism in this moment of historical crisis, whereby the state of today seems to have strong links to the state of the past. As part of Gestures of Resistance, artworks by sixteen international contemporary artists will be exhibited at the Romantso Cultural Centre in Athens during Documenta 14. From photographs and collages to sculptures and installations, each artist has an agenda and political take – some subtle and cryptic, some openly confrontational. Fisher will be exhibiting new and existing sculptural works from his, ‘Homemade Device’ series. Participating artists include: Bill Balaskas, Pavel Büchler, Broomberg and Chanarin, Edward Chell, Ian Dawson, Craig Fisher, Alfredo Jaar, Peter Kennard and Cat Phillipps, Steffi Klenz, Małgorzata Markiewicz, Louisa Minkin and Francis Summers, Terry Perk, Julian Rowe, Yorgos Sapountzis, Bob and Roberta Smith, Socratis Socratous, Wolfgang Tillmans, Jessica Voorsanger, Stuart Whipps
    • Micro

      Fisher, Craig; University of Derby (AIR Gallery, Altrincham, 2019)
      Fisher was selected to participate in the group exhibition, Micro at AIR Gallery which was an open theme exhibition of over 100 small works by rising stars in contemporary art, working across a vast range of media. Fisher exhibited a number of ‘Homemade Devices’ which were highly commended by exhibition selectors.
    • A Profound Difference

      Harris, Philip; University of Derby (Departure Lounge, 2019-07-20)
    • 8mm Cine Workshop

      Harris, Philip; University of Derby (Exposure Festival, 2020-02-03)
      Now considered obsolete, these old Bolex 8mm cine cameras were produced in the 1950s and promoted to families and amateur film makers. They are simple to use, fully manual, powered by a clockwork motor, with excellent build quality and optics. With care and application of basic cameras/photo skills and knowledge, they are capable of very good image quality. Being a physical medium, cine film allows the user capacity to experiment, in a very hands-on way, with editing, looping and use of multiple projectors to create montages of footage and images. The workshop can be based around a brief that explores the identities of Calgary – the physical, regional and cultural identities of the city. Users will be taught and guided in the camera controls, exposure settings, use of a handheld lightmeter (It would be very useful if the Uni can provide these. Sekonic 308 will suffice), and methods for handheld filming in a range of circumstances. They will then use this knowledge to produce film footage that interprets their response to Calgary. The scope of delivery and support will depend on how much time the Photo/Art department can dedicate to the workshop. A practical workshop on basic use can be delivered in 2 hours, including a visual presentation on my own work to present a rationale for the workshop. It would work best if this can then be supplemented by an hour or so of practical support with using the cameras and exposing film for the brief.

      Harris, Philip; Marmalade, Gemma; University of Derby (FORMAT, 2019-03-15)
      The conference for FORMAT19, 15th March 2019, was hosted by University of Derby and the Digital and Material Artistic Centre. In place of the single stream events that had taken place in previous years, the organisers arranged three parallel streams with over 30 contributors, many from outside the UK, and 200 delegates. This dramatic upscale in ambition produced the largest scale FORMAT conference in the history of the University of Derby. The selection of papers and presentations drew upon an open call by the organisers with the inclusion of selected participants in the FORMAT19 festival with rigorous review by both editors. The overall form and structure of the conference was developed, managed, and realised by the editors with a schedule of three streams titled in relation to the evocative theme of the festival, Forever//Now, as follows: 1. Myths, narratives and histories 2. Archiving the future 3. Territory, identity and memory Specific contributions by academics from the University of Derby/D-MARC: • Marc Boward provided a critical examination of digital montage as a means to visually negotiate issues of politics and history. • Gemma Marmalade’s (ed.) paper presented her performed intervention on the delivery of her paper for the project Green Fingered. • Philip Harris (ed.) presented a philosophical examination of obsolete media and its potential to examine issues of politics and social concerns. • Alys Russell provided a critical examination of domestic photography and its relationship with locative memory. • Dominic Chapman’s paper examined the collective mythologies and visual tropes employed by the Leave Campaign in the UK Referendum to leave the EU, 2016. • Mark Hall presented a critical examination of the Stephen Shore’s work American Surfaces. • Stephanie Rushton discussed the philosophical context for her project The Archaea, centred around ecology and intelligence in nature. The conference, in its drastically enlarged scale and scope, provided a highly valuable source of new knowledge across a highly diverse range of ideas, themes and issues, representing the diverse range of practices and themes in contemporary research on photography.
    • Forecasting US overseas travelling with univariate and multivariate models

      Apergis, Nicholas; University of Derby (Wiley, 2021-01-06)
      This study makes use of specific econometric modelling methodologies to forecast US outbound travelling flows to certain destinations: Europe, Caribbean, Asia, Central America, South America, Middle East, Oceania, and Africa, spanning the period 2000-2019 on a monthly basis. Both univariate (jointly with business conditions) and multivariate models are employed, while out-of-sample forecasts are generated and the results are compared based on popular forecasting performance criteria. These criteria show that in the case of univariate models, the largest forecasting gains are obtained when the modelling process follows the KS-AR(1) model with the business cycles being measured as the coincident indicator. In the case of multivariate models, the largest forecasting gains occur with the standard VAR model for very short forecasting horizons, and with the Bayesian VAR for longer horizons. The results are robust to both total and individual destinations. The findings allow interested stakeholders to gain insights into near-future US outbound tourism to popular diversified international destinations, as well as to better understand its positive and negative impacts for strategic planning and destination adaptation purposes.
    • A profound difference: Visualising politics through obsolete media

      Harris, Philip; University of Derby (Cambridge Scholars, 2020-12-17)
      This paper is a revised and edited version of that which was delivered at the conference for the FORMAT19 International Photography Festival, for which I acted as co-organiser and co-editor. An iteration of the paper was delivered at Exposure Photography Festival, Calgary, Canada, 2020, to support my exhibition in the festival in addition to a workshop on analogue cine media. The essay discusses the research into and use experimental use of media for a visual project, A Profound Difference, staged at the launch of FORMAT19, 15th March, at the University of Derby. A further iteration was presented for Departure Lounge, 20th July 2019. The visual project was made between October 2018 and March 2019. It was centred around concerns for the future circumstances of young people as a result of the UK referendum to leave the EU, held on the 26th June 2016. The project employed a very specific use of media in the form of continental, Standard 8mm cine film equipment dating from the 1950s, the rationale being that this was the media Europeans used to record their lives during the period in which the supra-national state of Europe was first being formed. The project was publicly staged as a largescale installation with multiple projectors throwing looped footage of the young people onto the sides of polling booths. Using the visual work as a vehicle, the essay describes theoretical research for the employment of obsolete media to engage with current political issues. I discuss theories of making with reference to Martin Heidegger, Gilbert Simondon, Elaine Scary, and Hito Steyerl, to create a framework for a critically informed use of obsolete visual media. My argument is that due to obsolete analogue media escaping the market drives of digital media, it has a potential to raise awareness of our current dependence on digital media for which we have questionable agency.
    • Machinability of INCONEL718 alloy with a porous microstructure produced by laser melting powder bed fusion at higher energy densities

      Wood, Paul; Díaz-Álvarez, Antonio; Díaz-Álvarez, José; Miguélez, María Henar; Rusinek, Alexis; Williams, Gavin; Bahi, Slim; Sienkiewicz, Judyta; Płatek, Paweł; Gunputh, Urvashi Fowdar; et al. (MDPI, 2020-12-15)
      Products produced by additive manufacturing (AM) seek to exploit net shape manufacturing by eliminating or minimizing post-process stages such as machining. However, many applications which include turbo machinery components with tight dimensional tolerances and a smooth surface finish will require at least a light machine finishing stage. This paper investigates the machinability of the additively fabricated INCONEL718 (IN718) alloy produced by laser melting powder bed fusion (LM-PBF) with different levels of spherical porosity in the microstructure. The literature suggests that the band width for laser energy density, which combines the various scan process parameters to obtain a low spherical type porosity in the LM-PBF IN718 alloy (~1%), has wide breadth. With the increasing laser energy density and above a threshold, there is a rapid increase in the spherical pore size. In this paper, three tube samples each with different levels of spherical porosity were fabricated by varying the laser energy density for LM-PBF of the IN718 alloy within the stable and higher energy density range and the porosity measured. A low laser energy density was avoided due to balling up, which promotes highly irregular lack of fusion defects and poor consolidation within the alloy microstructure. An orthogonal turning test instrumented, with a three-component dynamometer to measure the cutting forces, was performed on AM produced IN718 tube samples under light cut conditions to simulate a finish machining process. The orthogonal turning tests were also performed on a tube sample obtained from the wrought extruded stock. The machining process parameters, which were studied include varying the cutting speed at three levels, at a fixed feed and under dry cut conditions for a short duration to avoid the tool wear. The results obtained were discussed and a notable finding was the higher rate of built-up-edge formation on the tool tip from the AM samples with a higher porosity and especially at a higher cutting speed. The paper also discusses the mechanisms that underpin the findings.
    • Scoping review of the readiness for sustainable implementation of lean six sigma projects in the manufacturing sector

      Shokri, A., Antony, J., Garza-Reyes, J.A., Upton, M.; Northumbria University; Heriot-Watt University, Edinburgh; University of Derby; University of York (Emerald, 2021-01-11)
      This work presents a synthesis of current literature published from 2010 to provide an overall understanding of the sustainable implementation of Lean Six Sigma (LSS) projects in terms of project approaches rather than outcomes. A comprehensive and validated ten-step model was applied to conduct a scoping review (SR) with the following three broad phases: “review planning”, “review execution”, and “review reporting”. The analysis shows that while a few geographically and methodologically broad research studies have been conducted on LSS and green manufacturing integration, no studies have examined organisational culture or conducted readiness assessments on the sustainable implementation of LSS projects in the manufacturing sector. The present study contributes to existing knowledge by describing the current state of research on green LSS integration. The study also identifies a lack of research on the deployment of sustainable LSS projects for manufacturers. Further empirical analyses that include case studies must be conducted to assess the negative environmental impacts of LSS projects. This study serves as an initial call for practitioners and research scholars to favour the sustainable deployment of LSS projects in manufacturing alongside the use of traditional approaches with a focus on costs, quality and delivery.
    • Investigative empathy: Five types of cognitive empathy in a field study of investigative interviews with suspects of sexual offences

      Baker-Eck, Bianca; Bull, Ray; Walsh, Dave; University of Derby; De Montfort University (International Investigative Interviewing Research Group, 2021)
      Empathy in investigative interviews has increasingly become a focus in the recent literature on investigative interviewing as its implementation may aid in building and maintaining rapport. Displaying empathy in interviews is claimed to have positive impacts on the provision of investigation relevant information and the cooperation of interviewees. However, the literature currently omits practically operationalizing empathy, which would provide a means of implementing it effectively in investigative interviews. As such, the present study examines empathic displays by interviewers employed in interviews with suspects of high-risk crimes such as sexual offences in order to see what types are applied as a step towards identifying and possibly defining/operationalizing empathy during investigative interviews in the future. 19 audio-tapes of police interviews with suspects of sexual crimes in England and Wales conducted by experienced police interviewers were coded for their empathic displays and suspects’ level of cooperation throughout the interviews. Five different types of empathy were found to be employed. Interviews that had higher levels of suspect cooperation involved all five types of investigative empathy, whereas interviews in which fewer types of empathy were displayed had less cooperation (by offering less or no information). Thus, the use of investigative empathy in investigative interviews can indeed be recommended.
    • Positive psychology for mental wellbeing of uk therapeutic students: Relationships with engagement, motivation, resilience, and self-compassion.

      Kotera, Yasuhiro; Green, Pauline; Sheffield, David; University of Derby (Springer, 2020-01-12)
      This study aimed to examine the relationships between mental wellbeing and positive psychological constructs in therapeutic students (psychotherapy and occupational therapy students). The number of therapeutic students has increased recently, however they suffer from poor mental health, which may be improved by potentiating their positive psychological constructs, bypassing mental health shame. Therapeutic students (n=145) completed measures regarding positive psychological constructs, namely mental wellbeing, engagement, motivation, resilience, and self-compassion. Resilience and self-compassion predicted mental wellbeing, explaining a large effect. Self-compassion partially mediated the relationship between resilience and mental wellbeing. This study highlights the importance of positive psychological constructs, especially resilience and self-compassion, for mental wellbeing of therapeutic students.
