A critical examination of the effectiveness of faculty-based student learning support

This thesis presents an investigation into the effectiveness of faculty-based student learning support and comprises three volumes. Volume 1 provides an overview of the background literature, research methodology, ethical and reliability considerations linked to two projects whose overarching theme is the support and improvement of the student experience. The overview begins with an outline of the aim of this thesis, followed by a synopsis of the literature concerning student support in higher education and the use of technology to support learners. The methodological framework is then discussed and a brief introduction to the projects is provided. The overview concludes with an exploration of the effectiveness of faculty-based student learning support and the presentation of a new blended approach to the organisation, delivery and typology of advising. This seeks to demonstrate the strength of a blended approach and thus makes a contribution to the practice, theory and method of supporting student learning. Volume 2 discusses the Advice Shop project and considers the processes, methods and ethics of this student learning support. A summary of eight interventions is presented together with details of how the project was subsequently rolled out across the University. A consideration of the organisational model and personnel involved in student advising is also offered. The volume concludes with student and staff feedback and a discussion of how the project aims have been achieved. Evidence of the research output and components of practice relating to Project 1 can be found in Volume2 Part 2. Volume 3 presents a discussion of Project 2 - the use of technology to support learners. The project presents two technology-enhanced interventions - an electronic student attendance monitoring scheme, and the development of two online learner support tools using QuestionMark Perception as the delivery software. The methods and ethical considerations used to establish and implement these interventions are present together with feedback from students and staff. The volume concludes with a discussion of how the aims of the project have been achieved. Evidence of the research output and components of practice relating to Project 2 can be found in Volume 3 Part 2

A Direct Comparison of Lyman-Alpha and Neutral Hydrogen Morphologies

The Lyman-Alpha Reference Sample (LARS) and its extension (eLARS) represent an exhaustive campaign to reverse-engineer galaxies. The main goal is to understand how \lya radiation is transported within galaxies: what fraction of it escapes, and what physical properties affect the \lya morphology and radiative transport (e.g., dust and gas content, metallicity, kinematics, properties of the producing and underlying stellar populations). Two galaxies from the sample, LARS02 and LARS09, were observed using the B and C configurations of the Very Large Array to examine the neutral hydrogen emission, which can be used to determine a galaxy\u27s neutral hydrogen (HI) structure and kinematics. Images of the \HI mass surface density and of the intensity weighted \HI velocity field were created at angular scales of $\sim$8 arcseconds, which corresponds to $\sim$5 kpc for LARS02 and $\sim$8 kpc for LARS09. Extended \HI gas is detected at high significance up to $\sim$30 kpc from the optical body of LARS02. LARS09 has a severely disturbed optical morphology; our new \HI observations reveal that LARS09 is interacting with the nearby field galaxy SDSS J082353.65+280622.2. By combining these moment maps with direct imaging of the \lya morphology from the Hubble Space Telescope, this program has produced the first direct comparison of \lya and \HI morphologies. These observations demonstrate concept for a significant observational campaign to produce similar comparisons in the remaining 40 LARS and eLARS galaxies

An automated calibration method for non-see-through head mounted displays

Accurate calibration of a head mounted display (HMD) is essential both for research on the visual system and for realistic interaction with virtual objects. Yet, existing calibration methods are time consuming and depend on human judgements, making them error prone, and are often limited to optical see-through HMDs. Building on our existing approach to HMD calibration Gilson et al. (2008), we show here how it is possible to calibrate a non-see-through HMD. A camera is placed inside a HMD displaying an image of a regular grid, which is captured by the camera. The HMD is then removed and the camera, which remains fixed in position, is used to capture images of a tracked calibration object in multiple positions. The centroids of the markers on the calibration object are recovered and their locations re-expressed in relation to the HMD grid. This allows established camera calibration techniques to be used to recover estimates of the HMD display's intrinsic parameters (width, height, focal length) and extrinsic parameters (optic centre and orientation of the principal ray). We calibrated a HMD in this manner and report the magnitude of the errors between real image features and reprojected features. Our calibration method produces low reprojection errors without the need for error-prone human judgements

View-based modelling of human visual navigation errors

View-based and Cartesian representations provide rival accounts of visual navigation in humans, and here we explore possible models for the view-based case. A visual “homing” experiment was undertaken by human participants in immersive virtual reality. The distributions of end-point errors on the ground plane differed significantly in shape and extent depending on visual landmark configuration and relative goal location. A model based on simple visual cues captures important characteristics of these distributions. Augmenting visual features to include 3D elements such as stereo and motion parallax result in a set of models that describe the data accurately, demonstrating the effectiveness of a view-based approach

View-based approaches to spatial representation in human vision

In an immersive virtual environment, observers fail to notice the expansion of a room around them and consequently make gross errors when comparing the size of objects. This result is difficult to explain if the visual system continuously generates a 3-D model of the scene based on known baseline information from interocular separation or proprioception as the observer walks. An alternative is that observers use view-based methods to guide their actions and to represent the spatial layout of the scene. In this case, they may have an expectation of the images they will receive but be insensitive to the rate at which images arrive as they walk. We describe the way in which the eye movement strategy of animals simplifies motion processing if their goal is to move towards a desired image and discuss dorsal and ventral stream processing of moving images in that context. Although many questions about view-based approaches to scene representation remain unanswered, the solutions are likely to be highly relevant to understanding biological 3-D vision

INSIGHTS INTO THE THERAPEUTIC POTENTIAL OF SALT INDUCIBLE KINASE 1: A NOVEL MECHANISM OF METABOLIC CONTROL

Salt inducible kinase 1 (SIK1) has been considered a stress-inducible kinase since it was first cloned in 1999. Continued efforts since this time have been dedicated to characterizing the structure and function of SIK1. Such research has laid the ground work for our understanding of SIK1 action and regulation in tissue and stimuli dependent manners. The fundamental findings of this dissertation continue in this tradition and include investigations of SIK1 regulatory mechanisms in skeletal muscle cells, the cellular and physiological effects of SIK1 loss of function in vitro and in vivo, and intracellular metabolic and mitochondrial regulation by this kinase. Herein, evidence is provided demonstrating that skeletal muscle SIK1 regulates insulin sensitivity and blood glucose concentrations through mechanism(s) independent of the canonical insulin pathway. Our research addresses many previously unanswered questions about SIK1 action in metabolism and positions SIK1 as a potential therapeutic target for the treatment of metabolic disorders, such as type 2 diabetes, while provoking new questions for future research
