Possible Preventive Obesity Measures For Consideration In Labrador Retrievers Canis Lupus Familiaris According To Veterinarian And Owner Opinions, Sophie Bannister Jul 2013

Possible Preventive Obesity Measures For Consideration In Labrador Retrievers Canis Lupus Familiaris According To Veterinarian And Owner Opinions, Sophie Bannister

The Plymouth Student Scientist

Canine obesity is a persistent and ever-increasing chronic disease. This research investigated possible new and improved preventive obesity measures specific to the Labrador retriever dog breed. Quantitative analysis of questionnaire responses from 128 Labrador retriever owners and 46 veterinarians was used. Owners were asked to score the body condition of their Labrador retrievers using a series of pictograms ranging from 1-5 to establish body levels. Biological and environmental factors of the dogs were investigated to determine their effects on predisposition to body weight levels. The colour of the Labrador (Chi: χ² = 10.964; d.f. = 4; P<0.027) and the breed (Chi: χ² = 11.073; d.f. = 2; P<0.004) were associated with the dogs' levels of obesity whereas the Labrador's field/role (Chi: χ² = 3.240; d.f. = 2; P<0.198) was not. Comparison of veterinarians' opinions on such factors regarded coat colour (Chi: χ² = 1.22581; d.f. = 2; P>0.542) and breed …


Social Exclusion: The Effects Of Non-Mimicry On Self-Esteem, Need To Belong And Sociability, Elizabeth Templeman Jul 2013

Social Exclusion: The Effects Of Non-Mimicry On Self-Esteem, Need To Belong And Sociability, Elizabeth Templeman

The Plymouth Student Scientist

Although a great deal is known about mimicry, much less is known about non-mimicry in social interaction. The current research investigated the effects of social exclusion via non-mimicry on self-esteem, need to belong and motivation to socialise. Participants listened to music whilst nodding along to the beat, participants in an excluded condition listened to a faster version than those in an included condition causing the excluded participant to nod out of sync, creating a sense of social exclusion. Although the results found that participant’s self-esteem, need to belong and sociability were not affected by the experience of non-mimicry in social …


The Effects Of Self-Efficacy On Pro-Environmental Intentions, Kerrie Payne Jul 2013

The Effects Of Self-Efficacy On Pro-Environmental Intentions, Kerrie Payne

The Plymouth Student Scientist

The effect of self-efficacy on pro-environmental intentions was studied in thirty five individuals. Each participant was required to watch a fear-inducing global warming video and complete three separate questionnaires to monitor their emotion response, felt-responsibility and level of pro-environmental intention. There was very little difference presented between the self-efficacy condition and the control group, suggesting that self-efficacy had little effect on the level of pro-environmental intentions recorded. However there was a significant level of F(1,30) = 7.71, p=.009, discovered between the level of reported pro-environmental intention presented between Time one and Time two for the control group, suggesting that the …


Osmotic Regulation Of The Amphipod Gammarus Chevreuxi (Sexton, 1912), Sam Houston Jul 2013

Osmotic Regulation Of The Amphipod Gammarus Chevreuxi (Sexton, 1912), Sam Houston

The Plymouth Student Scientist

This study investigated osmotic regulation in the amphipod, Gammarus chevreuxi, and is the first publication of this organism’s osmotic regulatory curves. Unlike most estuarine amphipods studied to date which are hyperosmotic regulators, G. chevreuxi is a hyper-hyposmotic regulator. The hyperosmotic gradient maintained by G. chevreuxi in dilute media is very low (~120mmol.L-1), which has been interpreted as evidence of freshwater ancestry among the Crustacea. Salinity acclimation did not appear to affect heart rate or pleopod beat frequency. The gill cells responsible for ion uptake appeared to be smaller in high salinities or distorted. The apical membrane in concentrated media shows …


Key Factors That Influence Breeding Performance In Raptors, James Paviour Jul 2013

Key Factors That Influence Breeding Performance In Raptors, James Paviour

The Plymouth Student Scientist

Breeding performance is a broad term, the definition of which varies throughout the literature. In raptor species it is frequently used as an expression that refers to the total number of nestlings that adults can raise to a prescribed age per breeding attempt, however it has also been defined in terms of clutch size, hatching success, and nestling quality (Steenhoff and Newton 2007). Assessing the breeding performance of raptors (combined with assessment of adult survival rates) is crucial to understanding the health and condition of populations and the degree to which they are likely to persist in a given habitat …


A Study Evaluating What Best Inspires Visitor Behaviour And Attitude Changes In Zoos, With A Small Botanical Garden Comparison: Addressing Zoos' Educational And Subsequent Conservation Values, Sophie Lancaster Jul 2013

A Study Evaluating What Best Inspires Visitor Behaviour And Attitude Changes In Zoos, With A Small Botanical Garden Comparison: Addressing Zoos' Educational And Subsequent Conservation Values, Sophie Lancaster

The Plymouth Student Scientist

The planet is currently under intense stress, though unsustainable consumption carries on rising at an exponential rate. One explanation for this is ignorance, especially within developed nations. Governments and industry are under extensive pressure to increase awareness, if we are to achieve a sustainable future and prevent the loss of the natural world. Zoos with their high visitation numbers have a significant role to play in educating the public, which they declare as a main goal. This study focuses on how zoos can better achieve this educational and subsequent conservation goal by looking into what learning techniques at Dartmoor Zoo …


The Effects Of Mental Imagery On Implementation Intentions: Specifically In Regards To Exercise Goal Achievement, Nathan Trethewey Jul 2013

The Effects Of Mental Imagery On Implementation Intentions: Specifically In Regards To Exercise Goal Achievement, Nathan Trethewey

The Plymouth Student Scientist

Past research shows that mental imagery can be used to enhance the effectiveness of implementation intentions. The present study aims to expand this, proposing that mental imagery can be used to enhance the effectiveness of implementation intentions specifically in regards to exercise. Results support the hypothesis that when mental imagery is used to enhance the effectiveness of implementation intentions, participants are more likely to meet their exercise goals. Furthermore based on past research it was hypothesized that participants in the implementation intention and mental imagery condition would experience stronger cravings towards exercise however no significant difference between the groups was …

The Miocene Elevation Of Mount Everest, A Gébelin, A Mulch, C Teyssier, Et Al Jul 2013

The Miocene Elevation Of Mount Everest, A Gébelin, A Mulch, C Teyssier, Et Al

School of Geography, Earth and Environmental Sciences

The Neogene elevation history of the Mount Everest region is key for understanding the tectonic history of the world's highest mountain range, the evolution of the Tibetan Plateau, and climate patterns in East and Central Asia. In the absence of fossil surface deposits such as paleosols, volcanic ashes, or lake sediments, we conducted stable isotope paleoaltimetry based on the hydrogen isotope ratios (δ D) of hydrous minerals that were deformed in the South Tibetan detachment shear zone during the late Early Miocene. These minerals exchanged isotopically at high temperature with meteoric water (δ D water = 156% ± 5%) that …


Effect Of Osmotic Potential Of Activator Solution And Temperature On Viability And Vigour Of Wheat Seed, Mp Fuller, J Hamza Jun 2013

Effect Of Osmotic Potential Of Activator Solution And Temperature On Viability And Vigour Of Wheat Seed, Mp Fuller, J Hamza

School of Biological and Marine Sciences

Experiment was conducted to investigate if seed priming with polyethylene glycol (PEG) activator solutions affects the viability and vigour of deteriorating wheat (Triticum aestivum L. cv. Caxton) seed lot. Seeds were subjected to PEG priming solutions with varying osmotic potentials (-1, -2, -3 MPa) at temperatures of 15 or 20°C for 6, 12, 18 or 24 h and compared to the non-primed control. Highest germination percentage at first and final count, length of plumule and dry weight of seedling were all associated with Treatment 1 MPa/20°C/6 h (92%, 94%, 9.2 cm, 0.0133 mg, respectively) compared to the control (82.5%, 86%, …


Comparing Teacher Roles In Denmark And England, Peter Kelly, Hans Dorf, Nick Pratt, Ulrike Hohmann Jun 2013

Comparing Teacher Roles In Denmark And England, Peter Kelly, Hans Dorf, Nick Pratt, Ulrike Hohmann

Plymouth Institute of Education

This article reports the findings of a comparative study of teaching in Denmark and England; its broader aim is to help develop an approach for comparing pedagogy. Lesson observations and interviews identified the range of goals towards which teachers in each country worked and the actions these prompted. These were clustered using the lens of Bernstein’s pedagogic discourse (1990; 1996) to construct teacher roles which provided a view of pedagogy. Through this approach we have begun to identify variations in pedagogy across two countries. All teachers in this study adopted a variety of roles; of significance was the ease with …


Eviz - Energy Visualisation For Carbon Reduction, S Pahl, P De Wilde, J Goodhew, C Boomsma, Et Al Jun 2013

Eviz - Energy Visualisation For Carbon Reduction, S Pahl, P De Wilde, J Goodhew, C Boomsma, Et Al

School of Art, Design and Architecture

People play a key part in the energy performance of buildings, through design, operation control and management (Mahdavi, 2011). A building’s energy use can be 40 % above expectations (Yu et al., 2011) due to occupant behaviour. Occupants might heat empty rooms, open windows rather than turn down heating, and forget to turn the heating down when they leave the building (Parker et al., 2006). The eViz project presented here is a multi-centre project between four UK Universities that takes an integrated interdisciplinary approach between behaviour and building scientists to reduce energy use and thus carbon in buildings. Addressing the …


Space-Time Symmetries And The Yang-Mills Gradient Flow, Ld Debbio, A Patella, A Rago Jun 2013

Space-Time Symmetries And The Yang-Mills Gradient Flow, Ld Debbio, A Patella, A Rago

School of Engineering, Computing and Mathematics

The recent introduction of the gradient flow has provided a new tool to probe the dynamics of quantum field theories. The latest developments have shown how to use the gradient flow for the exploration of symmetries, and the definition of the corresponding renormalized Noether currents. In this paper we introduce infinitesimal translations along the gradient flow for gauge theories, and study the corresponding Ward identities. This approach is readily generalized to the case of gauge theories defined on a lattice, where the regulator breaks translation invariance. The Ward identities in this case lead to a nonperturbative renormalization of the energy-momentum …


Identifying Common Pressure Pathways From A Complex Network Of Human Activities To Support Ecosystem-Based Management, Am Knights, Rs Koss, La Robinson Jun 2013

Identifying Common Pressure Pathways From A Complex Network Of Human Activities To Support Ecosystem-Based Management, Am Knights, Rs Koss, La Robinson

School of Biological and Marine Sciences

The marine environment is heavily exploited, but unintentional consequences cause wide‐ranging negative effects to its characteristics. Linkage frameworks (e.g., DPSIR [driver–pressure–state–impact–response]) are commonly used to describe an interaction between human activities and ecological characteristics of the ecosystem, but as each linkage is viewed independently, the diversity of pressures that affect those characteristics may not be identified or managed effectively. Here we demonstrate an approach for using linkages to build a simple network to capture the complex relationships arising from multiple sectors and their activities. Using data‐analysis tools common to ecology, we show how linkages can be placed into mechanistically similar …


Numerical And Physical Modelling Of Extreme Waves At Wave Hub, Ej Ransley, M Hann, D Greaves, Ac Raby, D Simmonds Jun 2013

Numerical And Physical Modelling Of Extreme Waves At Wave Hub, Ej Ransley, M Hann, D Greaves, Ac Raby, D Simmonds

School of Engineering, Computing and Mathematics

With a history of international failures, the survivability of coupled systems of wave energy devices and their moorings, particularly those to be installed at development sites like Wave Hub, is surrounded by uncertainty. Potential design solutions require a better understanding of the hydrodynamics and structural loading experienced during extreme events, like rogue wave impact, in order to mitigate the risk of device and mooring failure. Rogue waves are waves with amplitudes far greater than those expected, given the surrounding sea conditions. Intense study into these events stems from their potential for catastrophic impact on ocean engineering structures. However, little is …


Six Decades Of Total Factor Productivity Change And Sources Of Growth In Bangladesh Agriculture (1948–2008), S Rahman, R Salim Jun 2013

Six Decades Of Total Factor Productivity Change And Sources Of Growth In Bangladesh Agriculture (1948–2008), S Rahman, R Salim

School of Geography, Earth and Environmental Sciences

This study applies the Färe–Primont index to calculate total factor productivity (TFP) indices for agriculture in 17 regions of Bangladesh covering a 61-year period (1948–2008). It decomposes the TFP index into six finer components (technical change, technical-, scale- and mix-efficiency changes, residual scale- and residual mix-efficiency changes). Results reveal that TFP grew at an average rate of 0.57% p.a. led by the Chittagong, Rajshahi, Rangpur, Dinajpur and Noakhali regions. TFP growth is largely powered by technological progress estimated at 0.74% p.a. Technical efficiency improvement is negligible (0.01% p.a.) due to stagnant efficiency in most of the regions. Decline in scale …


Probiotics, Prebiotics And Immunomodulation Of Gut Mucosal Defences: Homeostasis And Immunopathology., Holly Hardy, Jennifer Harris, Eleanor Lyon, Jane Beal, Andrew D. Foey May 2013

Probiotics, Prebiotics And Immunomodulation Of Gut Mucosal Defences: Homeostasis And Immunopathology., Holly Hardy, Jennifer Harris, Eleanor Lyon, Jane Beal, Andrew D. Foey

School of Biomedical Sciences

Probiotics are beneficial microbes that confer a realistic health benefit on the host, which in combination with prebiotics, (indigestible dietary fibre/carbohydrate), also confer a health benefit on the host via products resulting from anaerobic fermentation. There is a growing body of evidence documenting the immune-modulatory ability of probiotic bacteria, it is therefore reasonable to suggest that this is potentiated via a combination of prebiotics and probiotics as a symbiotic mix. The need for probiotic formulations has been appreciated for the health benefits in "topping up your good bacteria" or indeed in an attempt to normalise the dysbiotic microbiota associated with …

Peninsula Medical School

OBJECTIVES: Patients' trust in general practitioners (GPs) is fundamental to effective clinical encounters. Associations between patients' trust and their perceptions of communication within the consultation have been identified, but the influence of patients' demographic characteristics on these associations is unknown. We aimed to investigate the relative contribution of the patient's age, gender and ethnicity in any association between patients' ratings of interpersonal aspects of the consultation and their confidence and trust in the doctor. DESIGN: Secondary analysis of English national GP patient survey data (2009). SETTING: Primary Care, England, UK. PARTICIPANTS: Data from year 3 of the GP patient survey: …

Worsfold, Maeve C. Lohan, Melanie R. Edwards, Walter J. Shields, Courtney D. Sandau, Donald G. Patterson

School of Geography, Earth and Environmental Sciences

In human exposure studies involving Polychlorinated Biphenyls (PCBs), it is useful to establish when an individual was potentially exposed. Age dating PCB exposure is complex but assessments can be made because different PCB congeners have different residence times in the human body. The less chlorinated congeners generally tend to have shorter residence times because they are biotransformed and eliminated faster than more chlorinated congeners. Therefore, the presence of high proportions of less chlorinated congeners is often indicative of recent exposure. The 2003-04 National Health and Nutrition Examination Survey (NHANES) dataset contains results for the concentration of 37 PCBs in a …


Hepatitis C Virus, Cholesterol And Lipoproteins — Impact For The Viral Life Cycle And Pathogenesis Of Liver Disease, Daniel J. Felmlee, Mohamed Lamine Hafirassou, Mathieu Lefevre, Thomas F. Baumert, Catherine Schuster May 2013

Hepatitis C Virus, Cholesterol And Lipoproteins — Impact For The Viral Life Cycle And Pathogenesis Of Liver Disease, Daniel J. Felmlee, Mohamed Lamine Hafirassou, Mathieu Lefevre, Thomas F. Baumert, Catherine Schuster

Peninsula Medical School

Hepatitis C virus (HCV) is a leading cause of chronic liver disease, including chronic hepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. Hepatitis C infection associates with lipid and lipoprotein metabolism disorders such as hepatic steatosis, hypobetalipoproteinemia, and hypocholesterolemia. Furthermore, virus production is dependent on hepatic very-low-density lipoprotein (VLDL) assembly, and circulating virions are physically associated with lipoproteins in complexes termed lipoviral particles. Evidence has indicated several functional roles for the formation of these complexes, including co-opting of lipoprotein receptors for attachment and entry, concealing epitopes to facilitate immune escape, and hijacking host factors for HCV maturation and secretion. Here, we review …

How Managed A Market? Modes Of Commissioning In England And Germany, Rod Sheaff, Naomi Chambers, Nigel Charles, Mark Exworthy, Ann Mahon, Richard Byng, Russell Mannion May 2013

How Managed A Market? Modes Of Commissioning In England And Germany, Rod Sheaff, Naomi Chambers, Nigel Charles, Mark Exworthy, Ann Mahon, Richard Byng, Russell Mannion

Peninsula Medical School

Background: In quasi-markets governance over healthcare providers is mediated by commissioners. Different commissioners apply different combinations of six methods of control (’media of power’) for exercising governance: managerial performance, negotiation, discursive control, incentives, competition and juridical control. This paper compares how English and German healthcare commissioners do so. Methods: Systematic comparison of observational national-level case studies in terms of six media of power, using data from multiple sources. Results: The comparison exposes and contrasts two basic generic modes of commissioning: 1. Surrogate planning (English NHS), in which a negotiated order involving micro-commissioning, provider competition, financial incentives and penalties are the …

Peninsula Medical School

Background: The direction of health service policy in England is for more diversification in the design, commissioning and provision of health care services. The case study which is the subject of this paper was selected specifically because of the partnering with a private sector organisation to manage whole system redesign of primary care and to support the commissioning of services for people with long term conditions at risk of unplanned hospital admissions and associated service provision activities. The case study forms part of a larger Department of Health funded project on the practice of commissioning which aims to find the …


Resistance To Drought And Salt Stress After Regeneration And Micropropagation., F Hadi, Mp Fuller May 2013

Resistance To Drought And Salt Stress After Regeneration And Micropropagation., F Hadi, Mp Fuller

School of Biological and Marine Sciences

Investigation was made to confirm the stability of drought and salt stress tolerance in cauliflower (Brassica oleracea var.botrytis) mutants after regeneration and micropropagation. The N-nitroso-N-ethyleurea (NEU) and N-nitroso-N-methylurea (NMU) induced mutants of cauliflower were created and screened for drought and salt stress tolerance. The highly tolerant mutants were selected, regenerated by tissue culture techniques, screened again for drought and salt tolerance under in-vitro and in-vivo conditions, correlated the response of in vitro and in-vivo plants within a clone. Free proline levels in clones were correlated with stress tolerance. Results confirmed the persistence of mutations in clones with enhanced resistance levels …

‘Russia Wins Space Race’, N Barnett May 2013

‘Russia Wins Space Race’, N Barnett

School of Law, Humanities and Social Sciences

This article traces the development of the British press narrative from the launching of Sputnik in October 1957 to the Soviets' second satellite, containing a dog, in early November. It argues that there was an initial outpouring of surprise, combined with celebration of humankind's achievement. There was also a sense of loss of national prestige, due to Britain's lack of an equivalent space programme and the decline of her empire. The launch of the dog prompted widespread condemnation, mixed with frivolous popular coverage. The article provides an insight into how this moment impacted on British society and understanding of national …
