      The complex badland landscape at Tabernas results from a combination of relief amplitude generated by tectonic uplift since the Pliocene and reactivated several times during the Pleistocene, the properties of the Tortonian sedimentary rocks and a predominantly arid climate. The landscape is dominated by deep incision of the main river systems, which continues in part of the headwater tributaries, and characterized by contrasting slope morphologies and a variety of microecosystems. The Tabernas badlands exhibit a diversity of landforms resulting from the combination of multi-age soil surface components that allow a variety of processes to operate at different rates. These are dominated by rilling and shallow mass movements on south-facing hillslopes. On old surfaces and north-facing hillslopes, where biological components are present, overland flow with variable infiltration capacity and low erosion rates prevail. Incision in the gully bottoms occurs in the most active areas.
    • Bar deposition in glacial outburst floods: scaling, post-flood reworking, and implications for the geomorphological and sedimentary record

      Marren, Philip M.; University of Chester (GFG, 2016-03-31)
      The appearance of a flood deposit in the geomorphological and sedimentary record is a product of the both the processes operating during the flood, and those that occur afterwards and overprinting the deposit with a record of ‘normal’ processes. Nearly half of the total discharge of the November 1996 jökulhlaup on Skeiðarársandur was discharged through the Skeiðará river. The flood deposits have been extensively reworked since, up until 2009 when the channel was abandoned, effectively leaving the Skeiðará as a terrace, when retreat of Skeiðarárjökull directed meltwater to the adjacent Gígjukvísl river system. This paper describes the creation and modification of jökulhlaup barforms in the Skeiðará river, relating the changes to post-flood fluvial processes and glacier retreat. Large compound bars formed from the amalgamation of unit bars up to 1.5 km long. The location of the compound bars was governed by the macro-scale topography of the flood channel, and their size by upstream channel width in accordance with bar-scaling theory. Jökulhlaup bars are therefore scale invariant and formed in a similar fashion to braid bars in non-jökulhlaup braided rivers. Post-flood fragmentation and reworking of the bars consistently increased the length-width ratio of preserved bar fragments from approximately two and one half to over five. These observations increase our understanding of the preservation potential and final form of jökulhlaup deposits and provide the basis for an improved model for the recognition of jökulhlaup deposits in the geomorphological and sedimentary record.
    • Being ethically minded: Practising the scholarship of teaching and learning in an ethical manner

      The authors propose a working definition of ethical SoTL, an ethical framework for SoTL inquiry, and present a case study that illustrates the complexity of ethical issues in SoTL. The Ethical SoTL Matrix is a flexible framework designed to support SoTL practitioners, particularly in the formative stages of their inquiries. Three dominant ethical traditions form the basis of the matrix: teleological or pragmatic, external, and deontological. The key message of the paper is that SoTL practitioners should reflect on different perspectives in their efforts to do what is right in any given situation. The matrix introduces three dominant ethical traditions, but SoTL practitioners may ultimately move beyond these traditions to explore a range of ethical considerations appropriate to their projects and disciplines.
    • Biocrusts and catchment asymmetry in Tabernas Desert (Almeria, Spain)

      Lázaro, Roberto; Calvo-Cases, Adolfo; Rodriguez-Caballero, Emilio; Arnau-Rosalén, Eva; Alexander, Roy; Rubio, Consuelo; Cantón, Yolanda; Solé-Benet, Albert; Puigdefábregas, Juan; Estacion Experimental de Zonas Aridas (CSIC); Universitat de Valencia; Universidad de Almeria; Manchester Metropolitan University; University of Chester (Elsevier, 2021-10-15)
      Catchment asymmetry is a fairly frequent phenomenon on a global scale but the main causes leading to its formation are still not well understood. Where the intervention of structural or tectonic causes is not relevant, asymmetry seems to result from differential erosion between opposite slopes that flow into the same channel, which is frequently associated with contrasted biocrust and/or vegetation covers. Biocrusts are known to be important surface stabilizing agents. However, their geomorphological consequences at the landscape scale are little known. In this study we combined field measurements with digital elevation models and image analysis to determine whether catchment asymmetry in the Tabernas Desert (semi-arid SE of Spain) is a local or general phenomenon, and to explore the main factors determining asymmetry occurrence, magnitude and direction. We pay special attention to the role of biocrusts. We found that catchment asymmetry is a very common phenomenon in the area; only 25% of the catchments are symmetrical, while approximately 40% present asymmetry with the relatively shady hillslope having a lower gradient, and 35% with that hillslope being the steeper. Solar radiation reaching the soil, surface area and channel gradient in the considered catchment stretch, as well as the total catchment area upstream from the lower point of the considered stretch were the main abiotic factors controlling the formation of the asymmetry. Microclimatic differentiation due to differences in radiation input caused by the uneven topography favoured the relative stabilization of the shadier hillslope and its colonization by biocrusts and later by plants. The effect of the biocrusts and vegetation protection against water erosion on shadier hillslopes is often stronger than that of the set of abiotic factors and gives rise to asymmetries with lower gradients in the shady hillslope by promoting lateral displacement of the channel. We hypothesised that the opposite pattern, with the sunnier hillslope having a lower gradient, occurs when abiotic factors control the development of asymmetry formation. In these conditions, the effect of biocrusts and plants would act in the opposite direction. We propose a conceptual model of feedbacks generating catchment asymmetry, with biocrust playing a crucial role.
    • Bring Your Own Device (BYOD) in Higher Education: Opportunities and Challenges

      Miller, Servel; Welsh, Katharine E.; University of Chester (Nova Science Publishers, 2017-12-01)
      The recent growth of mobile device ownership provides significant opportunities for universities to utilise these devices to enhance the student experience. Bring Your Own Device (BYOD) allows students to use their own devices in an educational environment. This can provide opportunities such as students feeling more familiar with the technology, enabling personalisation of the devices, and could potentially reduce the cost of keeping up to date with new technology for higher education institutions. However a number of challenges also exist such as how to ensure students without mobile devices feel included and the issue of devices acting as a distraction. This chapter focuses on student’s perceptions of BYOD including how motivated they feel to learn and how they use their own devices in the classroom. The findings suggest that students are willing to use their own devices, they feel more motivated to learn and they feel more connected with teaching overall.
    • By any other name? The impacts of differing assumptions, expectations and misconceptions in bringing about resistance to student-staff ‘partnership’

      Healey, Ruth L.; Lerczak, Alex; Welsh, Katharine E.; France, Derek; University of Chester (McMaster University, 2019-05-07)
      Most of the existing literature on student-staff partnership explores the experiences of people who are keen to be involved and who have already bought into the ethos of students as partners. We explore the challenges of conducting student-staff partnership in the context of resistance. Specifically, we focus on the interpretations of ‘partnership’ by students and staff who were attempting to work in partnership for the first time. The views of the participants were captured during a six-month project in which four undergraduate students were employed to work with eight academics to re-design the second-year undergraduate curriculum on one programme. Notwithstanding an introductory briefing and on-going support, some participants showed indications of resistance. Our findings suggest that different perspectives on ‘partnership’ influenced participants’ experiences. We argue that assumptions and misconceptions around the terminology used to describe ‘students as partners’ practice may hinder the process itself, as some people may not ‘buy-in’ to the practice. However, despite the challenges of this project, the experience of being involved has led to reduced resistance and emerging partnership practices throughout the department.

    • Channel pattern of proglacial rivers: topographic forcing due to glacier retreat

      Marren, Philip M.; Toomath, Shamus C.; University of Melbourne (Wiley, 2014-02-14)
      Glacier retreat leads to changes in channel pattern during deglaciation, in response to changing water, sediment and base level controls. Recent ongoing retreat at Skaftafellsjökull, Iceland (c. 50m per year since 1998) has resulted in the formation of a sequence of river terraces, and several changes in river channel pattern. This paper compares widely used models of river channel pattern against the changes observed at Skaftafellsjökull. Doing this reveals the role of topographic forcing in determining proglacial channel pattern, whilst examining the predictive power and limitations of the various approaches to classifying river channels. Topography was found to play a large role in determining channel pattern in proglacial environments for two reasons: firstly, glacier retreat forces rivers to flow through confined moraine reaches. In these reaches, channels which theory predicts should be braided are forced to adopt a single channel. Secondly, proximal incision of proglacial rivers, accompanied by downstream aggradation, leads to changes in slope which force the river to cross channel pattern thresholds. The findings of this work indicate that in the short term, the majority of channel pattern change in proglacial rivers is due to topographic forcing, and that changes due to changing hydrology and sediment supply are initially relatively minor, although likely to increase in significance as deglaciation progresses. These findings have implications for palaeohydraulic studies, where changes in proglacial channel pattern are frequently interpretedas being due to changes in water or sediment supply. This paper shows that channel pattern can change at timescales faster than hydrological or sediment budget changes usually occur, in association with relatively minor changes in glacier mass balance.
    • Characterising beach intertidal bar systems using multi-annual LiDAR data

      Miles, Andrew; Ilic, Suzana; Whyatt, Duncan; James, Mike R.; University of Chester; Lancaster University (Wiley, 2019-02-05)
      Intertidal bars are common in meso-macrotidal low-to-moderate energy coastal environments and an understanding of their morphodynamics is important from the perspective of both coastal scientists and managers. However, previous studies have typically been limited by considering bar systems two-dimensionally, or with very limited alongshore resolution. This paper presents the first multi-annual study of intertidal alongshore bars and troughs in a macro-tidal environment using airborne LiDAR data to extract three-dimensional bar morphology at high resolution. Bar and trough positions are mapped along a 17.5 km stretch of coastline in the northwest of England on the eastern Irish Sea, using eight complete, and one partial, LiDAR surveys spanning 17 years. Typically, 3 – 4 bars are present, with significant obliquity identified in their orientation. This orientation mirrors the alignment of waves from the dominant south-westerly direction of wave approach, undergoing refraction as they approach the shoreline. Bars also become narrower and steeper as they migrate onshore, in a pattern reminiscent of wave shoaling. This suggests that the configuration of the bars is being influenced by overlying wave activity. Net onshore migration is present for the entire coastline, though rates vary alongshore, and periods of offshore migration may occur locally, with greatest variability between northern and southern regions of the coastline. This work highlights the need to consider intertidal bar systems as three-dimensional, particularly on coastlines with complex configurations and bathymetry, as localised studies of bar migration can overlook three-dimensional behaviour. Furthermore, the wider potential of LiDAR data in enabling high-resolution morphodynamic studies is clear, both within the coastal domain and beyond.

    • Coastal landslide mapping of the Black Ven Spittles complex, Charmouth

      Miller, Servel; Morris, Chloe; University of Chester (Dorset Natural History and Archaeological Society, 2014-01-01)
      Landslides are not generally perceived as natural hazards that significantly affect the UK. However, slope instability affects many parts of Britain including the Dorset and Devon coastline. Black Ven Spittles is a classic landslide complex along this coastline, exhibiting some of the largest and most dynamic landslips in Europe. It has a long history of instability with significant events occurring as recently as 2008 when a succession of rock falls occurred towards the western side of the complex, uncovering waste material from the old town tip. With the beach adjacent to the landslide regularly used by tourists, fossil hunters and locals for recreational activities, it is of paramount importance that landslides be mapped to determine the active areas. Such mapping may be used for effectively managing the risk posed for this landslide complex. Through field and geospatial mapping techniques utilising remote sensing imagery and Geographical Information Systems (GIS), the most updated geomorphic map of the landslide complex is presented. The maps produced as a result of this research identify how the ‘system’ has changed since 1996 when the most comprehensive geomorphic map prior to this research was published. The most active section of the landslide complex is near the village of Charmouth, which is popular with tourists and fossil-hunters. By identifying this increasing risk, management can be better informed and the public made more accurately aware of this natural hazard
    • Collaborative individualization? Peer-to-peer action in youth transitions

      Cuzzocrea, Valentina; Collins, Rebecca; University of Cagliari ; University of Chester (SAGE, 2015-04-23)
      In this paper we propose the notion of collaborative individualization (henceforth, C.I.) as a means of characterizing young people’s attempts to define their identities as simultaneously self-reliant and in need of support and collaboration. Our arguments are based on the findings of a transnational case study: a recent Council of Europe policy project called Edgeryders, an online platform whose participants were invited to discuss their experience of attempting to achieve “fully independent adulthood”. In light of findings which suggest that individualization amongst the young might take forms which are more collaborative than self-focused, we argue that youth scholars ought to rethink the assumptions made about the nature of individualization in youth transitions. We propose that such theorizations should embrace the potential described by C.I. in order to provide constructive responses to young people’s changing socio-economic needs, and refocus attention on young people’s situatedness within the communities many are demonstrably committed to working with and for.
    • Conceptions of ‘research’ and their gendered impact on research activity: A UK case study

      Healey, Ruth L.; Davies, Chantal; University of Chester (Taylor and Francis, 2019-08-31)
      The last twenty years have seen an increased emphasis around the world on the quality and quantity of research in response to national research assessments, international league tables, and changes in government funding. The prevailing attitude in higher education embeds research as the ‘gold standard’ in the context of academic activity. However, a key feature of this trend is significant gender differences in research activity. We argue that research productivity is related to identification as a researcher, and that identifying as ‘research-active’ or not would appear to depend upon how an individual academic subjectively defines ‘research’. This article brings together two hitherto separate bodies of work 1) the impact of gender on academic research careers, and 2) academic conceptions of research. Through a combination of interviews, focus groups and questionnaires, we investigate the extent to which interpretations of ‘research’ and ‘research activity’ differ by gender within an institution in the UK and the potential impact of these interpretations. Although the research found that there are many similarities in the interpretations of ‘research activity’ between genders, we found one important difference between male and female participants’ conceptions of research and its relationship to teaching. Significantly, our findings suggest that there is a need to expand our existing conceptualisations of ‘research’ to include ‘research as scholarship’ in order to address the obstacles that current understanding of ‘research’ have placed on some academics. Self-definition as a researcher underlies research activity. A narrow conception of ‘research’ may prevent individuals from identifying as ‘research-active’ and therefore engaging with research.
    • Contested spaces, new opportunities: displacement, return and the rural economy in Casamance, Senegal

      Evans, Martin; University of Chester (Zed Books, 2014-05-08)
      Casamance is the southwesternmost part of Senegal, largely separated from the rest of the country by The Gambia to the north and bordering Guinea-Bissau to the south. As the scene of West Africa’s longest-running civil conflict, now some 30 years old, Casamance provides a case of displacement economies on a relatively small scale but of long duration. The focus here is on human displacement, understood as the enforced physical dislocation of people, the dynamics of their return and resettlement, and the economic, political and social effects related to these processes. Much of the long-term human displacement in the conflict has occurred in the relatively narrow band of territory between the south bank of the Casamance River and northern border districts of Guinea-Bissau. Following flight and protracted exile from this border area in the 1990s, however, the 2000s and beyond have mostly seen people return, driven by economic and social desperation coupled with generally improved (though still at times volatile) security conditions, and supported by international aid for reconstruction. Building on field research conducted over twelve years, the chapter considers the emergent economic and political landscape of the border area. It shows how this landscape is the result of layers of displacement over two decades, situated within a deeper historical context of migration. From a theoretical perspective, it seeks to understand these dynamics through the concept of ‘relational space’, formulated in human geography and beginning to be used, if not always explicitly, in studies of displacement.
