Geoscience In A Rapidly Changing World: What Could Go Wrong?, Jr Zondervan May 2018

Geoscience In A Rapidly Changing World: What Could Go Wrong?, Jr Zondervan

School of Geography, Earth and Environmental Sciences

The application of geoscience to global development is starting to become more recognised. In particular, the role of geoscience in delivering the UN’s Sustainable Development Goals is discussed by some workers (e.g. Gill and Bullough, 2017). We are living through a time of rapid socio-political and economic change with the rise of globalisation, and it is an important time to ask what the role of geoscience will be in facilitating this change. Geoscience is increasingly supplying information about our environment on a global scale and applications are becoming more powerful. Deep ocean mining will respond to the rising demand for …

The Ultimate Fate Of A Synmagmatic Shear Zone. Interplay Between Rupturing And Ductile Flow In A Cooling Granite Pluton, I Zibra, Jc White, L Menegon, G Dering, K Gessner May 2018

The Ultimate Fate Of A Synmagmatic Shear Zone. Interplay Between Rupturing And Ductile Flow In A Cooling Granite Pluton, I Zibra, Jc White, L Menegon, G Dering, K Gessner

School of Geography, Earth and Environmental Sciences

The Neoarchean Cundimurra Pluton (Yilgarn Craton, Western Australia) was emplaced incrementally along the transpressional Cundimurra Shear Zone. During syndeformational cooling, discrete networks of cataclasites and ultramylonites developed in the narrowest segment of the shear zone, showing the same kinematics as the earlier synmagmatic structures. Lithological boundaries between aplite/pegmatite veins and host granitic gneiss show more intense pre-cataclasite fabrics than homogeneous material, and these boundaries later became the preferred sites of shear rupture and cataclasite nucleation. Transient ductile instabilities established along lithological boundaries culminated in shear rupture at relatively high temperature (~500–600 °C). Here, tensile fractures at high angles from the …

Experiencing Porcelain As A Landscape, P Davis Apr 2018

Experiencing Porcelain As A Landscape, P Davis

School of Art, Design and Architecture

In the late eighteenth century, the Plymouth Porcelain Factory produced sets of figures designed to represent what were then known as the four Continents: Asia, Africa, Europe and the Americas. As objects of middle-class consumption, they were designed not only to represent current ideas about the qualities of these continents, but also to allow consumers to have a relationship with places of which they had no first-hand knowledge, creating a geographical experience. Taking the historical nature of these figurines into consideration, this research considers whether it is possible to co-opt such artefacts into a twenty-first century geographical experience. Using a …

© 2018 Elsevier B.V. Recent reduction in high-latitude sea ice extent demonstrates that sea ice is highly sensitive to external and internal radiative forcings. In order to better understand sea ice system responses to external orbital forcing and internal oscillations on orbital timescales, here we reconstruct changes in sea ice extent and summer sea surface temperature (SSST) over the past 130,000 yrs in the central Okhotsk Sea. We applied novel organic geochemical proxies of sea ice (IP 25 ), SSST (TEXL86) and open water marine productivity (a tri-unsaturated highly branched isoprenoid and biogenic opal) to marine sediment core MD01-2414 (53°11.77′N, …

Social Enterprise And Community Resilience: Examining A Greek Response To Turbulent Times, N Apostolopoulos, R Newbery, M Gkartzios Apr 2018

Social Enterprise And Community Resilience: Examining A Greek Response To Turbulent Times, N Apostolopoulos, R Newbery, M Gkartzios

Plymouth Business School

Using community resilience and institutional entrepreneurship as conceptual lens, the paper explores whether support for social enterprises in non-metropolitan Greece has led to resilient social systems. Whilst drawing on narratives of enabling a bottom-up response to market failure, rather than radical or reformist adaptation, social enterprise may have produced a reluctant and state reliant response which may weaken the resilience of communities to survive continued austerity. The research selected and interviewed 30 social enterprises operating within non-metropolitan Greece during 2016. It contributes to knowledge through a novel framing, which clarifies that social enterprise in Greece remains a top-down governance process …

The Burnsian Palimpsest: Robert Burns In American Cultural Memory, C. 1840-1866, A Sood Apr 2018

The Burnsian Palimpsest: Robert Burns In American Cultural Memory, C. 1840-1866, A Sood

School of Law, Humanities and Social Sciences

Arguably more so than any other eighteenth-century literary figure, the political and popular legacy of Robert Burns has been continually contested, revised and appropriated to various ends. As recently as the 2015 UK General Election, the Scottish branch of the right-wing populist United Kingdom Independence Party (UKIP) attempted to win the hearts (if not the minds) of Scottish voters by producing posters emblazoned with lines from Burns’s ‘The Dumfries Volunteers’; while, previously, the opposing Scottish Nationalist Party strategically launched an electoral campaign on the poet’s birthday (Tempest 2005). Contests were also waged over Burns’s presumed political leanings during the 2014 …

Although there is increasing interest in how learning to become a researching professional is understood by students undertaking a professional doctorate of education (EdD), the topic remains under-researched and under-theorized. In this article, we provide a set of theorizations, starting with the purpose and distinctiveness of the professional doctorate and the researching professional identity as this is understood by students and staff participating in the EdD programme in one university in the United Kingdom (UK). This is followed by a retheorization of the researching professional as they develop a reflexive disposition to connect the workplace and the university as the …

The Role Of External Inputs And Internal Cycling In Shaping The Global Ocean Cobalt Distribution: Insights From The First Cobalt Biogeochemical Model, Alessandro Tagliabue, Nicholas J. Hawco, Randelle M. Bundy, William M. Landing, Angela Milne, Peter L. Morton, Mak A. Saito

School of Geography, Earth and Environmental Sciences

©2018. The Authors. Cobalt is an important micronutrient for ocean microbes as it is present in vitamin B 12 and is a co-factor in various metalloenzymes that catalyze cellular processes. Moreover, when seawater availability of cobalt is compared to biological demands, cobalt emerges as being depleted in seawater, pointing to a potentially important limiting role. To properly account for the potential biological role for cobalt, there is therefore a need to understand the processes driving the biogeochemical cycling of cobalt and, in particular, the balance between external inputs and internal cycling. To do so, we developed the first cobalt model …

Zaha Hadid's Penthouse: Gender, Creativity And "Biopolitics" In The Neoliberal Workplace, I Troiani

School of Art, Design and Architecture

This chapter studies and critically examines the practice space inside and outside Zaha Hadid’s penthouse apartment and discusses how her gender, the marketing of her creativity, and her designs can affect architecture’s starchitect “biopolitic.” It presents the story of Hadid’s penthouse in the context of Margaret Thatcher’s neoliberalism and refers to writings on the impact of neoliberalism generally, by Michel Foucault and Wendy Brown, to discuss how architectural production, at the corporate level, ties the body of the architect to an incessant drive for increased marketization through the concept of homo oeconomicus. The chapter argues that the economic man architects …

School of Geography, Earth and Environmental Sciences

AbstractSea ice and associated feedback mechanisms play an important role for both long- and short-term climate change. Our ability to predict future sea ice extent, however, hinges on a greater understanding of past sea ice dynamics. Here we investigate sea ice changes in the eastern Bering Sea prior to, across, and after the Mid-Pleistocene transition (MPT). The sea ice record, based on the Arctic sea ice biomarker IP25 and related open water proxies from the International Ocean Discovery Program Site U1343, shows a substantial increase in sea ice extent across the MPT. The occurrence of late-glacial/deglacial sea ice maxima are …

Did Sea-Level Change Cause The Switch From Fissure-Type To Central-Type Volcanism At Mount Etna, Sicily?, Iain S. Stewart Mar 2018

Did Sea-Level Change Cause The Switch From Fissure-Type To Central-Type Volcanism At Mount Etna, Sicily?, Iain S. Stewart

School of Geography, Earth and Environmental Sciences

One of the most intriguing aspects of the evolution of Mount Etna (eastern Sicily) is the switch from a fissure-type shield volcano coincident with the Ionian coast to an inland cluster of nested stratovolcanoes close to the currently active centre. Previous geological studies infer that the switch reflects a tectonicallydriven rearrangement of the major border faults that direct the Etnean plumbing system, loosely dated at around 125 ka BP. New offshore structural studies throw this prevailing view into question, whilst a revised chronological framework indicates that the transformation from fissure- to central-type activity was abrupt, effectively occurring 129-126 ka BP. …
