Dynamics Of Suspended Particulate Matter In The Lower Tamar Estuary, Emlyn Davies
Dynamics Of Suspended Particulate Matter In The Lower Tamar Estuary, Emlyn Davies
The Plymouth Student Scientist
This project uses a combination of different measuring techniques to investigate the distribution and size of Suspended Particulate Matter within the lower reaches of the Tamar Estuary and Plymouth Sound. Data of particle concentrations and sizes, along an ebb and flood transect of the lower Tamar estuary, are presented and analysed. Expected trends of a reduction in particle concentration towards the mouth (from 7mg.L-1 to 5mg.L-1) were detected. A decrease in particle size from 170μm furthest upstream, to 140μm near the mouth, was also observed. Significant relationships between particle size and organic concentration were found, with correlation coefficients of r …
Attachment Theory: In Search Of A Relationship Between Attachment Security And Preschool Children's Level Of Empathy, Rebecca Knight
Attachment Theory: In Search Of A Relationship Between Attachment Security And Preschool Children's Level Of Empathy, Rebecca Knight
The Plymouth Student Scientist
The ability to empathise has frequently been advocated as the driving force behind pro-social behaviour. The tender and nurturing environment inherently provided by mothers of securely attached children, constructs an ambience which promotes the development of empathy and implicates the role of attachment theory in explaining individual differences in empathy. Investigated in 58 preschool children, using 8 pictorial scenes portraying four emotions – happiness, sadness, anger and fear, children were invited to rate emotions elicited for both the character and self. Results supported the main prediction that securely attached children would be more empathic than insecurely attached children (p < .001), thus indicating that the route for increasing pro-social behaviour may lie within the realms of attachment theory.
The Effect Of Mood On Attention To Global And Local Characteristics Of Music, Jennifer Pope
The Effect Of Mood On Attention To Global And Local Characteristics Of Music, Jennifer Pope
The Plymouth Student Scientist
The effect of mood on global and local processing was studied in 60 undergraduate psychology students, half of which were randomly assigned to a positive condition and the other half to a negative condition. Each participant carried out same-different judgements on pairs of melodies that were either the same, or altered globally or locally. Key findings included significant differences in performance for all melodies; however despite a trend for enhanced local processing in a negative mood compared to a positive mood, the effect of mood on global and local processing failed to reach statistical significance. These findings suggest that mood …
Vocabulary Acquisition In Bilingual Children: Are They More Delayed In English Than Their Monolingual Peers? Does This Depend On Input Of Language?, Naomi Kilgore
The Plymouth Student Scientist
The current study investigated the effect of exposure to English on bilingual language acquisition. 18 monolingual and 6 bilingual children, aged between 29 -32 months, took part in standardised language tests measuring productive and comprehensive vocabulary. Although previous research has investigated this, not all variables known to affect vocabulary development have been controlled for. This study controlled for socio-economic status, birth order and different levels of exposure to English and compared these to test scores. Results suggest exposure is a significant predictor of productive (p = .01) and comprehensive (p < .01) language development. A greater difference was found between groups for production (p < .01) supporting previous research suggesting production may be more problematic than comprehension for bilingual children.
Investigating The Nature Of Body Representations And Their Use In Pair Matching And Mental Rotation Tasks, Abigail Clifton
Investigating The Nature Of Body Representations And Their Use In Pair Matching And Mental Rotation Tasks, Abigail Clifton
The Plymouth Student Scientist
Two computer based stimulus-response experiments were conducted with the aim of finding whether Body Representations aid pair matching and mental rotations of 'same‘ or 'different‘ Bodies in comparison to Bicycles. Also to find whether 'disconnecting‘ Body Stimuli would disrupt the BSD and increase RTs. Sixteen different University of Plymouth students took part in each experiment, 32 overall. No significant effects were found for pair matching alone. Body Stimuli were rotated significantly more quickly than Bicycle Stimuli in Experiment 2. This effect was attributed to participants utilising their Body Representations to perform the rotations in a more holistic way. No effect …
In Vitro Micropropagation Of Medicinal Plants By Tissue Culture, Yaadwinder Sidhu
In Vitro Micropropagation Of Medicinal Plants By Tissue Culture, Yaadwinder Sidhu
The Plymouth Student Scientist
Tissue culturing of medicinal plants is widely used to produce active compounds for herbal and pharmaceutical industries. Conservation of genetic material of many threatened medicinal plants also involves culturing techniques. This work reviews in vitro micropropagation techniques and gives examples of various commercially important medicinal plants. The effect of media formulations and culturing techniques on the growth and multiplication of medicinal plants; and on the production of secondary metabolites is also reviewed. Another method of obtaining secondary metabolites is biotransformation; some famous pharmaceuticals obtained by this method are discussed briefly.
Psychological Flexibility, Insomnia And Chronic Pain: A Study Of Acceptance, Mindfulness And Values-Based Action, Jennifer Williams
Psychological Flexibility, Insomnia And Chronic Pain: A Study Of Acceptance, Mindfulness And Values-Based Action, Jennifer Williams
The Plymouth Student Scientist
Whilst thought control strategies are becoming increasingly recognised as counterproductive, the role of psychological flexibility has been observed in depression, anxiety and chronic pain, however little research has considered its role in insomnia. It was hypothesised that psychological flexibility would predict levels of insomnia. Participants were 162 male and female adults seeking chronic pain treatment who completed a set of questionnaires measuring four variables of psychological flexibility and insomnia severity. Results indicated that measures of psychological flexibility were significant correlated with measures of sleep quality. Multiple regression analysis revealed that collectively, chronicity of pain, usual pain intensity and measures of …

The Effect Of Dietary Inclusion Of Category 3 Animal By-Product Meals On Rainbow Trout (O. Mykiss Walbaum) Mineralised Tissues And Immune Function., Matthew Alun Griffiths Owen
School of Biological and Marine Sciences Theses
Aquaculture is growing rapidly worldwide and is projected to become the major source of fish used for human consumption. A major factor that limits aquaculture reaching its full potential is an adequate supply of the raw materials necessary for formulated fish feeds. The dependence of modern aquaculture on fishmeal obtained from wild fisheries is not environmentally sustainable and replacements for fishmeal must be found. Some animal by-products are viable replacements for fishmeal, and can provide sufficent nutrition for high growth rates, but little is known about the potential of animal by-products to adversely affect fish health. The objectives of these …

Communities Of Praxis? Scholarship And Practice Styles Of The He In Fe Professional, K. Gale, R. Turner, L. M. Mckenzie
Plymouth Institute of Education
The Dearing Report advocated that the traditionally separate post-compulsory education sectors of English higher education (HE) and further education (FE) should bring together the academic and vocational in a working partnership. This has led to significant changes in the working practices of colleges, lecturers and support staff. Drawing on the experiences of a sample of HE lecturers in colleges in south west England and a synthesis of relevant literature, this paper begins to examine the practice styles of HE lecturers working in FE institutions and the opportunities they are presented to engage with scholarship. The research acknowledges the issues involved …

Rn181 Suppresses Hepatocellular Carcinoma Growth By Inhibition Of The Erk/Mapk Pathway, S Wang, X Huang, Y Li, H Lao, Et Al
School of Biomedical Sciences
UNLABELLED: The activation of oncogenes and the inactivation of tumor suppressor genes by mutations or chronic hepatitis virus infections play key roles in the pathogenesis of hepatocellular carcinoma (HCC). Here we report that RN181, a really interesting new gene finger domain-containing protein, was down-regulated in highly malignant cell lines and in tumor cells of 139 HCC clinical samples in comparison with adjacent normal liver tissues. The expression of RN181 was strongly associated with the pathological grade of HCC. Alterations of the expression of RN181 by retrovirus-transduced up-regulation and short hairpin RNA-mediated down-regulation demonstrated the function of RN181 as a tumor …
Does Undergraduate Curriculum Design Make A Difference To Readiness To Practice As A Junior Doctor?, Alan Bleakley, Nicola Brennan
Does Undergraduate Curriculum Design Make A Difference To Readiness To Practice As A Junior Doctor?, Alan Bleakley, Nicola Brennan
More Faculty of Health Research
Background: Undergraduate medicine curricula can be designed to enable smoother transition to work as a junior doctor. Evaluations should improve curriculum design. Aim: To compare a graduate cohort from one medical school with a cohort from other medical schools in the same Foundation Year 1 (FY1) programme in terms of retrospective perceptions of readiness for practice. Method: A Likert-scale questionnaire measured self-perception of readiness to practice, including general capabilities and specific clinical skills. Results: Response rate was 74% (n=146). The Peninsula Medical School cohort reported readiness for practice at a significantly higher level than the comparison cohort in 14 out …

Automatic And Ironic Behavior Are Both Mediated By Changes In The Self-Concept, Na Wyer, H Neilens, Tj Perfect, G Mazzoni
Automatic And Ironic Behavior Are Both Mediated By Changes In The Self-Concept, Na Wyer, H Neilens, Tj Perfect, G Mazzoni
School of Psychology
Recent accounts suggest that prime-to-behavior effects are mediated by changes to the active self-concept. Likewise, recent reports of post-suppression behavioral rebound have attributed changes to behavior to changes in the self-concept. According to such accounts, whenever an activated trait or stereotype can be easily incorporated into the active self, behavioral assimilation (i.e., behavior consistent with the activated concept) is likely to ensue. Yet, little evidence has emerged to directly support the mediating role of changes to the self-concept. The present research was designed to examine whether changes to the active self-concept are responsible for changes in behavior following stereotype suppression …

David Link – Machine Heart, G Cox
David Link – Machine Heart, G Cox
School of Art, Design and Architecture
In his work David Link generates (apparently) interactive projects, at the interface between art, science, and technology. For LoveLetters_1.0, Link reconstructed a functional replica of one of the earliest programmable computers, the Ferranti Mark I, and an equally early program, invented in 1952 by Christopher Strachey at the University of Manchester. To produce computer-generated love letters, written using a built-in random generator. Anonymously addressed to “Darling Love” or “Jewel Duck,” the letters talk to the reader in a surprisingly human and tender way. In his introduction, Geoff Cox highlights the question, already suggested by the apparently contradictory title of this …

Air Temperature And Winter Mortality: Implications For The Persistence Of The Invasive Mussel, Perna Viridis In The Intertidal Zone Of The South-Eastern United States, Lb Firth, Am Knights, S Bell
School of Biological and Marine Sciences
Global climate change and invasive species represent two of the biggest threats to the environment. Biological communities are responding to global climate change through poleward shifts in distribution, and changes in abundance and phenology of both native and non-native species. An increase in the frequency and magnitude of extreme weather events is predicted with global climate change. Much is known about mortality events of marine organisms in relation to warm thermal stress with relatively little known about cold thermal stress, particularly in the tropics. Intertidal species are particularly susceptible to fluctuations in aerial conditions and many are considered indicators of …

Phase 1 Pilot Study Of E-Mail Support For People With Long Term Conditions Using The Internet., Bryony Sheaves, Ray B. Jones, Graham R. Williamson, Rohan Chauhan
School of Nursing and Midwifery
BACKGROUND: Use of the Internet for people with Long Term Conditions (LTCs) can have a positive effect on knowledge, social support, behavioural and clinical outcomes, yet there is concern that a 'digital divide' prevents some patients from benefitting. While some patients do not have access to the Internet, others that do may still lack expertise or the confidence to make full use of it. The aim of this pilot study was to develop an intervention and test methods for a definitive randomised controlled trial (RCT) of anonymous personal online email support for patients in this latter group. METHODS: Recruitment success …
Resource Use Efficiency Under Self‐Selectivity: The Case Of Bangladeshi Rice Producers, S Rahman
Resource Use Efficiency Under Self‐Selectivity: The Case Of Bangladeshi Rice Producers, S Rahman
School of Geography, Earth and Environmental Sciences
The paper jointly evaluates the determinants of switching to modern rice and its productivity while allowing for production inefficiency at the level of individual producers. Model diagnostics reveal that serious selection bias exists, justifying the use of a sample selection framework in stochastic frontier models. Results revealed that modern variety selection decisions are influenced positively by the availability of irrigation and gross return from rice and negatively by a rise in the relative wage of labour. Adoption of modern rice is higher in underdeveloped regions. Seasonality and geography/location does matter in adoption decisions. Stochastic production frontier results reveal that land, …

The Predictive Mirror: Interactions Of Mirror And Affordance Processes During Action Observation, P Bach, Ap Bayliss, Sp Tipper
The Predictive Mirror: Interactions Of Mirror And Affordance Processes During Action Observation, P Bach, Ap Bayliss, Sp Tipper
School of Psychology
An important question for the study of social interactions is how the motor actions of others are represented. Research has demonstrated that simply watching someone perform an action activates a similar motor representation in oneself. Key issues include (1) the automaticity of such processes, and (2) the role object affordances play in establishing motor representations of others' actions. Participants were asked to move a lever to the left or right to respond to the grip width of a hand moving across a workspace. Stimulus-response compatibility effects were modulated by two task-irrelevant aspects of the visual stimulus: the observed reach direction …
The Face Inhibition Effect: Social Contrast Or Motor Competition?, Sp Tipper, P Bach
The Face Inhibition Effect: Social Contrast Or Motor Competition?, Sp Tipper, P Bach
School of Psychology
Merely viewing the faces of famous athletes affects the observers' motor system, suggesting that actionbased information is a core feature of person representations, even when no specific action is visible (Bach & Tipper, 2006). Unexpectedly, these person-based motor priming effects were inhibitory. Foot responses were slower when identifying footballers, and hand responses for tennis players. Here, we demonstrate that these inhibitory effects are only evoked when action is implicitly associated with the athletes; when the athletes are seen performing their skilled actions the effect reverses towards facilitation. The contrast between inhibition evoked by implicit action priming and facilitation evoked by …
Unstable Territories Of Representation: Architectural Experience And The Behaviour Of Forms, Spaces And The Collective Dynamic Environment, Sana Murrani
Other Faculty of Arts, Humanities and Business Theses
This thesis applies an interdisciplinary cybernetic and phenomenological analysis to contemporary theories of representation and interpretation of architecture, resulting in a speculative theoretical model of architectural experience as a behavioural system. The methodological model adopted for this research defines the main structure of the thesis where the narrative and the contributing parts of its complexity emerge. The narrative is presented through objectives and hypotheses that shift and slide between architectural representation and its experience based on three key internal components in architecture: the architectural forms and spaces, the active observers that interact with their environment, and finally, the responsive environment. …

Behavioural Profiling In Mobile Networks, Ibrahim Zincir
Other Faculty of Science and Engineering Theses
In the last 20 years mobile devices gained an important role in daily life and became must have items for everyone. As mobile devices give us the much needed flexibility and mobility, they also represent one major concern; security. As the information is transmitted from node to node via radio frequencies, an imposter can gain access into a mobile network without the need to gain physical access to firewalls and gateways. Also, as they are light and small, mobile devices are easily lost and often used without any PIN or password protection enabled. Hence, it is not difficult for someone …
An Investigation Into Use Of The Freshwater Gastropod Viviparus As A Recorder Of Past Climatic Change, Melanie Bugler
An Investigation Into Use Of The Freshwater Gastropod Viviparus As A Recorder Of Past Climatic Change, Melanie Bugler
Other Faculty of Science and Engineering Theses
Through isotopic analysis of Viviparus lentus (V. lentus) a high resolution record of stepwise changes in δ18O and δ13C across the Eocene / Oligocene transition and Oi-1 glacial maximum has been produced for the continental Solent Group strata, Isle of Wight (UK). Comparison of this V. lentus δ18Ocarb. record with high resolution marine δ18Ocarb. records shows that similar isotopic shifts exist in the near coastal continental and marine realms. In order to calculate palaeotemperatures from this new continental record an investigation into the biology of modern Viviparus and its effect on the isotopic composition of its shell carbonate was undertaken. …
