Improved Isotopic Model Based On 15N Tracing And Rayleigh‐Type Isotope Fractionation For Simulating Differential Sources Of N2O Emissions In A Clay Grassland Soil, A Castellano‐Hinojosa, N Loick, E Dixon, Gp Matthews, Et Al
Improved Isotopic Model Based On 15N Tracing And Rayleigh‐Type Isotope Fractionation For Simulating Differential Sources Of N2O Emissions In A Clay Grassland Soil, A Castellano‐Hinojosa, N Loick, E Dixon, Gp Matthews, Et Al
School of Geography, Earth and Environmental Sciences
Rationale Isotopic signatures of N2O can help distinguish between two sources (fertiliser N or endogenous soil N) of N2O emissions. The contribution of each source to N2O emissions after N-application is difficult to determine. Here, isotopologue signatures of emitted N2O are used in an improved isotopic model based on Rayleigh-type equations. Methods The effects of a partial (33% of surface area, treatment 1c) or total (100% of surface area, treatment 3c) dispersal of N and C on gaseous emissions from denitrification were measured in a laboratory incubation system (DENIS) allowing simultaneous measurements of NO, N2O, N2 and CO2 over a …

The Impact Of Superfast Broadband, Tailored Booklets For Households, And Discussions With General Practitioners On Personal Electronic Health Readiness: Cluster Factorial Quasi-Randomized Control Trial., Philip Abbott-Garner, Janet Richardson, Ray B. Jones
School of Nursing and Midwifery
BACKGROUND: Electronic health (eHealth) may improve health outcomes, but many people remain digitally excluded. Personal readiness to use the internet for health may be limited by lack of internet infrastructure, personal skills, social support, service provision, and cost. The impact of interventions to reduce these barriers is unknown. From 2011, the British Government supported the implementation of "superfast" broadband (Superfast) across the rural county of Cornwall. This provided the opportunity to assess the impact of interventions at regional, practice, and household levels. OBJECTIVE: This study aimed to assess the impact of 3 interventions on personal eHealth readiness: (1) regional-level implementation …

Peninsula Medical School
Background: Homelessness has increased by 165% since 2010 in England, with evidence from many settings that those affected experience high levels of mortality. In this paper we examine the contribution of different causes of death to overall mortality in homeless people recently admitted to hospitals in England with specialist integrated homeless health and care (SIHHC) schemes. Methods: We undertook an analysis of linked hospital admission records and mortality data for people attending any one of 17 SIHHC schemes between 1st November 2013 and 30th November 2016. Our primary outcome was death, which we analysed in subgroups of 10th version international …

Policy Decisions And Tourism: Unintended Consequences Or Deliberate Neglect – Reactions To The Ban On Term Time Holidays In The Uk’S South West, A Walmsley
Plymouth Business School
This study explores reactions of the tourism industry in the UK’s South West to a change in regulations governing term time leave. It serves as an example of the impact of non-tourism specific policy making on tourism. Data were collected from 260 tourism firms via an online survey. Findings confirm a largely negative response to the change in regulations. The study illustrates divergent reactions to the regulations within one stakeholder group, here the tourism sector and by implication highlights the limitations of a naïve application of stakeholder theory. The study also offers insights into the nature of resilience within the …

The Paleolimnologist's Guide To Compound-Specific Stable Isotope Analysis – An Introduction To Principles And Applications Of Csia For Quaternary Lake Sediments, J Holtvoeth, Jh Whiteside, S Engels, Fs Freitas, Et Al
School of Geography, Earth and Environmental Sciences
the stable isotope composition of key chemical elements for life on Earth (e.g., carbon, hydrogen, nitrogen, oxygen, sulfur) tracks changes in fluxes and turnover of these elements in the biogeosphere. Over the past 15–20 years, the potential to measure these isotopic compositions for individual, source-specific organic molecules (biomarkers) and to link them to a range of environmental conditions and processes has been unlocked and amplified by increasingly sensitive, affordable and wide-spread analytical technology. Paleoenvironmental research has seen enormous step-changes in our understanding of past ecosystem dynamics. Vital to these paradigm shifts is the need for well-constrained modern and recent analogues. …
Empirical Investigation Of Data Analytics Capability And Organizational Flexibility As Complements To Supply Chain Resilience, R Dubey, A Gunasekaran, Sj Childe, Wamba S Fosso, D Roubaud, C Forupon
Empirical Investigation Of Data Analytics Capability And Organizational Flexibility As Complements To Supply Chain Resilience, R Dubey, A Gunasekaran, Sj Childe, Wamba S Fosso, D Roubaud, C Forupon
Plymouth Business School
Supply chain resilience and data analytics capability have generated increased interest in academia and among practitioners. However, existing studies often treat these two streams of literature independently. Our study model reconciles two different streams of literature: data analytics capability as a means to improve information-processing capacity and supply chain resilience as a means to reduce a ripple effect in supply chain or quickly recover after disruptions in the supply chain. We have grounded our theoretical model in the organisational information processing theory (OIPT). Four research hypotheses are tested using responses from 213 Indian manufacturing organisations collected via a pre-tested survey-based …
Hazardous Plastics In Swiss Lakes?, Montserrat Filella, Andrew Turner
Hazardous Plastics In Swiss Lakes?, Montserrat Filella, Andrew Turner
School of Geography, Earth and Environmental Sciences
The accumulation and impacts of plastic litter in marine environments has received an extensive attention over the past decade. In contrast, littering in the freshwater environment has received relatively little study, despite the presence of plastics on the shores and beds of lakes and suspended in the lentic water column that are likely to pose the same problems to wildlife as marine plastics. Regardless of the type of water system, the majority of research in this area has targeted the presence of plastics themselves and, sometimes, their accumulation of persistent organic micropollutants (e.g., PCBs, PAHs). Only very recently attention has …

Nasty, Brutish And Short? The Life Cycle Of An Iron Age Round House At Black Loch Of Myrton, Sw Scotland., A Crone, G Cavers, E Allison, K Davies, Et Al
School of Geography, Earth and Environmental Sciences
Excavations at Black Loch of Myrton, Dumfries & Galloway are revealing the very well-preserved remains of an Iron Age settlement, the wetland context ensuring that the timber structures have remained intact and that the detritus of daily occupation survives for us to pick apart and understand. One of the structures in this settlement is an exceptionally well-preserved roundhouse, the material remains of which have been subjected to a barrage of analyses encompassing the insect, macroplant, bone and wood assemblages, soil micromorphology, faecal steroids, radiocarbon-dating and dendrochronology. These will enable us to address some of the key issues regarding the life …
National Menace: Mediating Homo/Sexuality And Sovereignty In The Polish National/Ist Discourses, R Kulpa
National Menace: Mediating Homo/Sexuality And Sovereignty In The Polish National/Ist Discourses, R Kulpa
School of Law, Humanities and Social Sciences
The bio-political discourses of nationhood and homo/sexuality burgeon geo-culturally and historically, and this article presents a case-study of Poland post-2004 EU enlargement. Focused on the (televised) presidential media orchestrations of the ‘EU and homosexual menace’ and parliamentary resolutions, the tensions between nationhood and sexuality are analysed through the prisms of dislocation, surplus, rhetoric of fear and antagonism. The presented argument: (1) discusses the complex simultaneity of discursive relations (rejection and dependency, flagrancy and obscurity, desire and abjection) spanning political and cultural narratives; (2) accentuates the evocative role of the emotive repertoire of media strategies deployed in the political and cultural …

The Changing Face Of The Mediterranean–Land Cover, Demography And Environmental Change: Introduction And Overview, Andrew Bevan, Alessio Palmisano, Jessie Woodbridge, Ralph Fyfe, Neil Roberts, Stephen Shennan
School of Geography, Earth and Environmental Sciences
This paper introduces a special issue on The Changing Face of the Mediterranean: Land Cover, Demography, and Environmental Change, which brings together up-to-date regional or thematic perspectives on major long-term trends in Mediterranean human–environment relations. Particularly, important insights are provided by palynology to reconstruct past vegetation and land cover, and archaeology to establish long-term demographic trends, but with further significant input from palaeoclimatology, palaeofire research and geomorphology. Here, we introduce the rationale behind this pan-Mediterranean research initiative, outline its major sources of evidence and method, and describe how individual submissions work to complement one another.
Autoxidation Of The Sea Ice Biomarker Proxy Ipso 25 In The Near-Surface Oxic Layers Of Arctic And Antarctic Sediments, Jean François Rontani, Lukas Smik, Simon T. Belt
Autoxidation Of The Sea Ice Biomarker Proxy Ipso 25 In The Near-Surface Oxic Layers Of Arctic And Antarctic Sediments, Jean François Rontani, Lukas Smik, Simon T. Belt
School of Geography, Earth and Environmental Sciences
© 2019 Over the last decade or so, the mono- and di-unsaturated highly branched isoprenoid (HBI) lipids IP 25 (Ice Proxy with 25 carbon atoms) and IPSO 25 (Ice Proxy for the Southern Ocean with 25 carbon atoms) have emerged as useful proxies for sea ice in the Arctic and Antarctic, respectively. A more complete understanding of their respective proxy signatures, however, requires more detailed knowledge of their stability in the water column and in sediments. In the current study, we focused on the autoxidation of IPSO 25 , first by performing laboratory-based oxidation reactions on a purified sample and …

Early Ipswichian (Last Interglacial) Sea Level Rise In The Channel Region: Stone Point Site Of Special Scientific Interest, Hampshire, England., R Briant, M Bates, S Boreham, N Cameron, Et Al
School of Geography, Earth and Environmental Sciences
Constraining the speed of sea level rise at the start of an interglacial is important to understanding the size of the ‘window of opportunity’ available for hominin migration. This is particularly important during the last interglacial when there is no evidence for significant hominin occupation anywhere in Britain. There are very few finer grained fossiliferous sequences in the Channel region that can be used to constrain sea level rise and they are preserved only to the north of the Channel, in England. Of these, the sequence at Stone Point SSSI is by far the most complete. Data from this sequence …

Mineralogical Constraints On The Thermal History Of Martian Regolith Breccia Northwest Africa 8114, Jl Macarthur, Jc Bridges, Lj Hicks, R Burgess, Et Al
School of Geography, Earth and Environmental Sciences
© 2018 The Authors Martian meteorite Northwest Africa (NWA) 8114 – a paired stone to NWA 7034 – provides an opportunity to examine the thermal history of a martian regolith and study near-surface processes and ancient environmental conditions near an impact crater on Mars. Our study reports petrographic and alteration textures and focuses on pyroxene and iron oxide grains. Some of the pyroxene clasts show exsolution lamellae, indicating a high temperature magmatic origin and slow cooling. However, transmission electron microscopy reveals that other predominantly pyroxene clasts are porous and have partially re-crystallised to form magnetite and a K-bearing feldspathic glassy …
Butterflies Embrace Maladaptation And Raise Fitness In Colonizing Novel Host, C Parmesan, M Singer
Butterflies Embrace Maladaptation And Raise Fitness In Colonizing Novel Host, C Parmesan, M Singer
School of Biological and Marine Sciences
We illustrate an evolutionary host shift driven by increased fitness on a novel host, despite maladaptation to it in six separate host-adaptive traits. Here, local adaptation is defined as possession of traits that provide advantage in specific environmental contexts; thus individuals can have higher fitness in benign environments to which they are maladapted than in demanding environments to which they are well adapted. A population of the butterfly Euphydryas editha adapted to a long-lived, chemically well-defended host, Pedicularis, had traditionally been under natural selection to avoid the ephemeral, less-defended Collinsia. The lifespan of Collinsia was so short that it senesced …

School of Geography, Earth and Environmental Sciences
High-latitude ecosystems are among the fastest warming on the planet1. Polar species may be sensitive to warming and ice loss, but data are scarce and evidence is conflicting2,3,4. Here, we show that, within their main population centre in the southwest Atlantic sector, the distribution of Euphausia superba (hereafter, ‘krill’) has contracted southward over the past 90 years. Near their northern limit, numerical densities have declined sharply and the population has become more concentrated towards the Antarctic shelves. A concomitant increase in mean body length reflects reduced recruitment of juvenile krill. We found evidence for environmental controls on recruitment, including a …
