An Alternative Way For Kosovar Adults To Earn A High School Equivalency Diploma: A Case Study, Gjylbehare Llapi Jan 2017

An Alternative Way For Kosovar Adults To Earn A High School Equivalency Diploma: A Case Study, Gjylbehare Llapi

Education

For many years, at the end of the last century, Kosovo was a country plagued with political, social, and economic strife that forced an entire generation of children and young adults to go virtually uneducated. Kosovo is paying a price for that today, with many of its adults finding themselves unskilled, under-educated and unemployed. The central topic and the purpose of the study was to identify possible programming options available to Kosovo’s authorities to increase the number of adults who possess an upper secondary school diploma. After conducting extensive research of possible alternatives offered in a number of countries, this …

North Atlantic Rhodolith Beds, Jazmin J. Hernandez-Kantun, Jason M. Hall-Spencer, Jacques Grall, Walter Adey, Fabio Rindi, Christine A. Maggs, Ignacio Bárbara, Viviana Peña Jan 2017

North Atlantic Rhodolith Beds, Jazmin J. Hernandez-Kantun, Jason M. Hall-Spencer, Jacques Grall, Walter Adey, Fabio Rindi, Christine A. Maggs, Ignacio Bárbara, Viviana Peña

School of Biological and Marine Sciences

Aggregations of living unattached corallines, previously often referred to as nodules, were given the name rhodoliths by Bosselini and Ginsburg ( 1971 ). Adey and MacIntyre ( 1973 ) provided an early discussion of their genesis and distribution. Such aggregations have long been known as maerl in the North East Atlantic, a Breton term for unattached thalli that lack a shell or pebble core (Irvine and Chamberlain 1994 ). Here, we provide an overview of rhodolith/maerl occurrence in the colder/temperate waters of the North Atlantic and summarize the distribution, species composition, biodiversity and ecological importance of these habitats.

Supporting The Retention Of Non-Traditional Students In Higher Education Using A Resilience Framework, Dre Cotton, T Nash, P Kneale Jan 2017

Supporting The Retention Of Non-Traditional Students In Higher Education Using A Resilience Framework, Dre Cotton, T Nash, P Kneale

Plymouth Institute of Education

Student drop-out in higher education is an increasingly important issue across Europe, but there are substantial disparities between countries and institutions which suggest that variations in policies and practices may influence student retention and success. Numerous schemes have been devised to increase student retention, frequently focusing on non-traditional groups. Retention efforts include scholarships and bursaries, enhanced monitoring and support measures, and specialist teams of staff or peer mentors. Theoretical understanding of the withdrawal of non-traditional students typically draws on social and cultural capital concepts (Bourdieu, 1986), which may have led to a rather deterministic approach to student success. Research with …

Wave Directional Spreading From Point Field Measurements, M. L. Mcallister, V. Venugopal, A. G.L. Borthwick Jan 2017

Wave Directional Spreading From Point Field Measurements, M. L. Mcallister, V. Venugopal, A. G.L. Borthwick

School of Engineering, Computing and Mathematics

Ocean waves have multidirectional components. Most wave measurements are taken at a single point, and so fail to capture information about the relative directions of the wave components directly. Conventional means of directional estimation require a minimum of three concurrent time series of measurements at different spatial locations in order to derive information on local directional wave spreading. Here, the relationship between wave nonlinearity and directionality is utilized to estimate local spreading without the need for multiple concurrent measurements, following Adcock & Taylor (Adcock & Taylor 2009 Proc. R. Soc. A 465 , 3361–3381. ( doi:10.1098/rspa.2009.0031 )), with the assumption …

Flow Through A Very Porous Obstacle In A Shallow Channel, M. J. Creed, S. Draper, T. Nishino, A. G.L. Borthwick Jan 2017

Flow Through A Very Porous Obstacle In A Shallow Channel, M. J. Creed, S. Draper, T. Nishino, A. G.L. Borthwick

School of Engineering, Computing and Mathematics

A theoretical model, informed by numerical simulations based on the shallow water equations, is developed to predict the flow passing through and around a uniform porous obstacle in a shallow channel, where background friction is important. This problem is relevant to a number of practical situations, including flow through aquatic vegetation, the performance of arrays of turbines in tidal channels and hydrodynamic forces on offshore structures. To demonstrate this relevance, the theoretical model is used to (i) reinterpret core flow velocities in existing laboratory-based data for an array of emergent cylinders in shallow water emulating aquatic vegetation and (ii) reassess …

Air Permeability Of Balsa Core, And Its Influence On Defect Formation In Resin Infused Sandwich Laminates, Rk Cullen, Sm Grove, J Summerscales Jan 2017

Air Permeability Of Balsa Core, And Its Influence On Defect Formation In Resin Infused Sandwich Laminates, Rk Cullen, Sm Grove, J Summerscales

School of Engineering, Computing and Mathematics

Many large composite structures are manufactured using sandwich laminates to achieve high specific bending strength and stiffness. For wind turbine blades, the self-weight becomes increasingly important as blade size increases. Resin infusion of three-dimensional sandwich laminates can result in complex flow paths, and subsequent defect formation is difficult to predict. The core material used for sandwich construction and its interaction with liquid resins may also influence the formation of defects. In the case of balsa, this effect can be used to reduce defect severity. This paper considers the effect of cored sandwich laminate construction on the formation of defects. The …

A Novel Batteryless Pacemaker: Design, Development, And In Vivo Study In An Ovine Model, Sajid Mehmood Asif Jan 2017

A Novel Batteryless Pacemaker: Design, Development, And In Vivo Study In An Ovine Model, Sajid Mehmood Asif

Electrical and Computer Engineering

A standard pacemaker can improve a patient's quality of life and may even prolong it, but conventional pacemakers contain leads and batteries, which have their own complications. Hence, the need for a pacemaker with leadless and batteryless capabilities is becoming increasingly important, as it reduces infection risk, device failure, and patient discomfort. Unlike other leadless pacing technologies, the proposed method in this work does not require a battery or leads. More specifically, a novel leadless pacemaker was proposed that harvest energy from radio frequency (RF), using a metamaterial-based rectenna, to power the pacemaker and stimulate the myocardium. Initially, path loss …

Asymptotic Residual Stress Distribution Induced By Multipass Welding Processes, P Ferro, F Berto, Nm James Jan 2017

Asymptotic Residual Stress Distribution Induced By Multipass Welding Processes, P Ferro, F Berto, Nm James

School of Engineering, Computing and Mathematics

In the high cycle fatigue (HCF) regime, the fatigue strength of welded joints is influenced by residual stresses (RS) induced during welding processes. If the weld toe is modelled via a sharp V-notch, the distribution of weld toe residual stress can be shown to be asymptotic with a singularity which follows either the linear-elastic or elastic-plastic solution depending on parameters that range across material properties, specimen clamping conditions, and the welding process. For thicker plates, multipass welding is used instead of single-pass welding to reduce the heat input and hence the width of the fusion zone (FZ) and heat-affected zone …

Examining Ngo Performance: A Case Of The Cluster Approach, Brian Jason Thomas Jan 2017

Examining Ngo Performance: A Case Of The Cluster Approach, Brian Jason Thomas

Emergency Management

The need for coordinated efforts to respond to emerging crises, disasters, and conflicts has become ever-more apparent in the past decade. As events occur more frequently, at a larger scale, and the 24 hour news cycle associated with cable networks and the web-based media enhanced the public’s exposure to disasters, the need for coordination has become more apparent. To that end the United Nations implemented the Cluster Approach. In the decade since its deployment, starting with the Pakistan Earthquake of 2006, little independent academic research has been conducted to assess the approach. Instead, the literature tends to be confined to …

Regional-Scale Probabilistic Shoreline Evolution Modelling For Flood-Risk Assessment, Stuart Stripling, Michael Panzeri, Belen Blanco, Kate Rossington, Paul Sayers, Alistair Borthwick Jan 2017

Regional-Scale Probabilistic Shoreline Evolution Modelling For Flood-Risk Assessment, Stuart Stripling, Michael Panzeri, Belen Blanco, Kate Rossington, Paul Sayers, Alistair Borthwick

School of Engineering, Computing and Mathematics

Rapid deterministic modelling of shoreline evolution at regional and coastal-scheme scale enables Monte-Carlo simulations by which long-term shoreline statistics can be estimated. This paper describes UnaLinea, a fast, accurate finite difference solver of the one-line sediment continuity equation. The model is verified for the evolution of an initially straight shoreline of a plane beach subject to regular breaking waves at constant angle of incidence in the presence of either a groyne or a continuous single-point feed of sediment. Grid convergence and stability tests are used to obtain accurate, stable results, with satisfactory computational efficiency. Influences of wave input filtering and …

Neural Correlates Of Evidence Accumulation During Value-Based Decisions Revealed Via Simultaneous Eeg-Fmri, M. Andrea Pisauro, Elsa Fouragnan, Chris Retzler, Marios G. Philiastides Jan 2017

Neural Correlates Of Evidence Accumulation During Value-Based Decisions Revealed Via Simultaneous Eeg-Fmri, M. Andrea Pisauro, Elsa Fouragnan, Chris Retzler, Marios G. Philiastides

School of Psychology

AbstractCurrent computational accounts posit that, in simple binary choices, humans accumulate evidence in favour of the different alternatives before committing to a decision. Neural correlates of this accumulating activity have been found during perceptual decisions in parietal and prefrontal cortex; however the source of such activity in value-based choices remains unknown. Here we use simultaneous EEG–fMRI and computational modelling to identify EEG signals reflecting an accumulation process and demonstrate that the within- and across-trial variability in these signals explains fMRI responses in posterior-medial frontal cortex. Consistent with its role in integrating the evidence prior to reaching a decision, this region …
