Why Can't We Be Friends?: The Effects Of Disclosure And Severity On Typical Students' Attitudes Toward Peers With Autism Spectrum Disorders, Jacqueline M. Dowjotas, '09 Jan 2009

Why Can't We Be Friends?: The Effects Of Disclosure And Severity On Typical Students' Attitudes Toward Peers With Autism Spectrum Disorders, Jacqueline M. Dowjotas, '09

Honors Projects

The autism spectrum disorders (ASDs) are characterized by deficits in social interaction, communication, and restrictive and repetitive behaviors and interests. Although many children with autism desire social interaction, they tend to have a difficult time mastering conversation skills and socially appropriate behavior. In addition, they have fewer and lower quality friendships when compared to typical peers, and they often face negative stigma from their typical peers. The current study was used to investigate typical students' attitudes toward hypothetical peers with varying degrees of ASDs. Participants (N = 61) read and responded to vignettes that depicted adolescents, in which severity of …

The Effects Of Medial Septal Modification On The Theta Rhythm Of The Amygdala, Colleen E. Mcshane, '09 Jan 2009

The Effects Of Medial Septal Modification On The Theta Rhythm Of The Amygdala, Colleen E. Mcshane, '09

Honors Projects

The theta rhythm is a 3- 1 2 Hz electroencephalographic (EEG) oscillatory phenomenon that has been recorded from the hippocampus of small animals during large motor movements, periods of arousal, and memory tasks. Theta denotes the amount of brain synchrony occurring, with higher theta amplitude corresponding to more synchrony among individual neurons. The proposed pacemaker of the hippocampal theta rhythm is the medial septal area (MSA), which consists of neurons that fire rhythmically in frequencies corresponding to the theta rhythm. Despite the proven physical connection between the MSA and the amygdala, there is uncertainty as to whether the MSA serves …

The Internet As Playground And Factory, Robert T. Scholz Jan 2009

The Internet As Playground And Factory, Robert T. Scholz

School of Engineering, Computing and Mathematics Theses

"Free labour" is central to the Internet. Traditional exploitation of labour was complemented by the monetization of attention between the 1880s and 1950s and then by the commoditization of networked publics starting in the 1980s. Today, commercial interests have colonized the Internet and "labour" is being performed online by hundreds of millions of people. Without being recognized as "labour", it turns profits for corporations. Playful, virtual volunteerism, and social production, driven by the desire for praise, entertainment, and peer recognition, has become a significant driving force of consumer capitalism. I am introducing the term "interactivity labour" to discuss the complex …

Memory And Metamemory In Patients With Temporal Lobe Epilepsy, Charlotte Emma Howard Jan 2009

Memory And Metamemory In Patients With Temporal Lobe Epilepsy, Charlotte Emma Howard

School of Psychology Theses

It is well established that patients with temporal lobe epilepsy (TLE) commonly report memory difficulties. The aim of this thesis was to use a novel approach adopting Nelson & Narens' (1990) theoretical framework to investigate whether metacognitive knowledge and memory performance were differentially disrupted in patients with TLE. More specifically, investigating to what extent poor memory in TLE could result from inadequate metamemory monitoring, inadequate metamemory control or both. Experiment I employed a combined Judgement-of-Learning and Feeling-of-Knowing task to investigate whether participants could monitor their memory successfully at both the item-by-item and global levels. The results revealed a dissociation between …

Iterative Approaches To Planning And Strategizing: Learning From The Architectural Studio Model, Shannon Chance Jan 2009

Iterative Approaches To Planning And Strategizing: Learning From The Architectural Studio Model, Shannon Chance

Conference papers

This paper investigates linear and non-linear strategies for organizing and planning, and explores how these strategies correlate to both higher education and architectural education. The study reveals that the strategies for planning and designing typically employed in the field of architecture reflect the sort of non-linear, iterative, and synthesizing processes scholars recommend universities use to improve the effectiveness of strategic planning (Birnbaum, 1988; Cutright, 2001; Presley & Leslie, 1999; Rowley, Lujan, & Dolence, 1998; Swenk, 2001). Opportunities abound for using design processes to enhance various institutional operations as explored in Proposal for using a studio format to enhance institutional advancement …

To Give Is Better Than To Receive: The Benefits Of Peer Review To The Reviewer’S Own Writing, Wendy Baker, Kristi Lundstrom

Faculty Publications

Although peer review has been shown to be beneficial in many writing classrooms, the benefits of peer review to the reviewer, or the student giving feedback, has not been thoroughly investigated in second-language writing research. The purpose of this study is to determine which is more beneficial to improving student writing: giving or receiving peer feedback. The study was conducted at an intensive English institute with ninety-one students in nine writing classes at two proficiency levels. The ‘‘givers’’ reviewed anonymous papers but received no peer feedback over the course of the semester, while the ‘‘receivers’’ received feedback but did not …

Do Emotions Have Distinct Vocal Profiles? A Study Of Idiographic Patterns Of Expression, Bruce L. Brown, Matthew M. Spackman, Sean Otto Jan 2009

Do Emotions Have Distinct Vocal Profiles? A Study Of Idiographic Patterns Of Expression, Bruce L. Brown, Matthew M. Spackman, Sean Otto

Faculty Publications

Research on vocal expressions of emotion indicates that persons can identify emotions from voice with relatively high accuracy rates. In addition, fairly consistent vocal profiles for specific emotions have been identified. However, important methodological issues remain to be addressed. In this paper, we address the issue of whether there are individual differences in the manner in which particular emotions may be expressed vocally and whether trained speakers’ portrayals of emotion are in some sense superior to untrained speakers’ portrayals. Consistent support was found for differences across speakers in the manner in which they expressed the same emotions. No accompanying relationship …

Emitter-Wrap-Through Photovoltaic Dipole Antenna With Solar Concentrator, Maria Roo Ons, S. Shynu, Max Ammann, Sarah Mccormack, Brian Norton

Articles

A novel photovoltaic dipole antenna employing a solar concentrator as a reflector is proposed. Four identical emitter-wrap-through rear contact solar cells connected in series as a folded dipole are simultaneously used for power generation and as the antenna radiating element, which is located in the focal line of a parabolic solar concentrator. The parabolic structure acts as a solar concentrator for the photovoltaic cells as well as a reflector for the folded dipole antenna. Full-wave electromagnetic simulation with supportive experimental work validates this design. The measured fractional impedance bandwidth and gain were 21% and 11.1 dBi, respectively. The antenna/solar arrangement …

Generalised Design Process For Fiber-Bend-Loss-Based Edge Filters For A Wavelength Measurement System, Pengfei Wang, Gerald Farrell, Yuliya Semenova Jan 2009

Generalised Design Process For Fiber-Bend-Loss-Based Edge Filters For A Wavelength Measurement System, Pengfei Wang, Gerald Farrell, Yuliya Semenova

Articles

We investigate and present a generalized methodology for the design of a fiber-bend-loss-based edge filter, starting with the task of evaluating and selecting suitable fibers and then considering the design of a fiber-bending-loss edge filter. As an example to illustrate the methodology, a Corning SMF28e fiber with a 900 μmdiameter is selected and two sample edge filters are designed for experimental verification. The designed edge filters are compact, easy to fabricate, meet target spectral specifications, and show low polarization-dependent loss, confirming the effectiveness of the proposed methodology for fiber-bend-loss-based edge filter design.

Microstrip-Fed Dual-Frequency Annular-Slot Antenna Loaded By Split-Ring-Slot, Xiulong Bao, Max Ammann Jan 2009

Microstrip-Fed Dual-Frequency Annular-Slot Antenna Loaded By Split-Ring-Slot, Xiulong Bao, Max Ammann

Articles

A compact dual-band annular-slot antenna loaded by a concentric split-ring-slot is presented. A stepped microstrip feedline enables the control of the coupling and provides good matching. The annular-slot is connected to the split-ring-slot by a rectangular slot, which increases the surface of the current path, thus notably reducing the resonant frequency for a given size. The embedded split-ring-slot structure allows many resonant modes to be realised. By tuning the key parameters, these operating modes and their bandwidths can be controlled. A wide bandwidth can be realised for either the lower band, upper band or both bands simultaneously, depending on the …

Sms Fibre Structure For Temperature Measurement Using A Simple Intensity-Based Interrogation System, Agus Hatta, Ginu Rajan, Yuliya Semenova, Gerald Farrell Jan 2009

Sms Fibre Structure For Temperature Measurement Using A Simple Intensity-Based Interrogation System, Agus Hatta, Ginu Rajan, Yuliya Semenova, Gerald Farrell

Articles

A singlemode–multimode–singlemode (SMS) fibre structure for temperature measurement that utilises a simple intensity-based interrogation system is proposed. The temperature dependence of the SMS fibre structure utilised as a sensor is investigated numerically and experimentally. It is found that a strong temperature dependence for the SMS fibre structure exists at selected wavelengths. The temperature characteristic at such wavelengths is linear in nature and can be used for temperature measurements. The proposed temperature sensor offers a high resolution and accuracy, and also benefits from a simple configuration and low cost when compared to other fibre-optic temperature sensors.

Use Of A Single-Multiple-Single-Mode Fiber Filter For Interrogating Fiber Bragg Grating Strain Sensors With Dynamic Temperature Compensation, Qiang Wu, Muhammad Hatta, Yuliya Semenova, Gerald Farrell

Articles

An interrogation technique for fiber Bragg grating (FBG) strain sensors with dynamic temperature compensation using a single-multiple-single-mode (SMS) fiber filter as a temperature compensating element is presented. Experimental results show that this technique offers a resolution of better than 3:4 με for strain measurements in the range from 0 to 1667 με, and the temperature induced error is as low as 34 με in the temperature range from 10 to 60 °C. The temperature induced error could be further reduced if the temperature sensitivity (the rate of temperature induced wavelength shift) of the SMS filter was closer to that of …

Estimating Dysphonia Severity In Continuous Speech: Application Of A Multi-Parameter Spectral/Cepstral Model, Christopher Dromey, Shaheen N. Awan, Nelson Roy

Faculty Publications

The purpose of the study was to identify a sub-set of spectral/cepstral-based analysis methods that would most effectively predict dysphonia severity (as estimated via auditory-perceptual analysis) in samples of continuous speech. Acoustic estimates of dysphonia severity were used as an objective treatment outcomes measure in a set of pre- vs post-treatment speech samples. Pre- and post-treatment continuous speech samples from 104 females with primary muscle tension dysphonia (MTD) were rated by listeners using a 100 point visual analogue scale (VAS) and analysed acoustically with spectral/cepstral-based measures. Stepwise linear regression produced a three-factor model consisting of the cepstral peak prominence (CPP); …

Laryngeal-Level Amplitude Modulation In Vibrato, Christopher Dromey, Lorie Reese, J Arden Hopkin Jan 2009

Laryngeal-Level Amplitude Modulation In Vibrato, Christopher Dromey, Lorie Reese, J Arden Hopkin

Faculty Publications

Summary: The goal of this investigation was to test a new methodology for measuring amplitude modulation (AM) at the level of the vocal folds during vibrato in trained singers, because previous research has suggested that AM arises in large part as an acoustic epiphenomenon through an interaction of the harmonics in the laryngeal source with the resonances of the vocal tract as the fundamental frequency oscillates. A within-subjects model was used to compare vocal activity across three pitch and three loudness conditions. Seventeen female singers with a range of training and experience were recorded with a microphone and an electroglottograph …

The Potential Of Asynchronous Video In Online Education, Michael E. Griffiths, Charles R. Graham Jan 2009

The Potential Of Asynchronous Video In Online Education, Michael E. Griffiths, Charles R. Graham

Faculty Publications

There are differences in the benefits that are afforded by the two extremes of face-to-face and distance education. University campus courses are based on the assumption that the student community and interaction between learners and an expert teacher in the same physical location is essential to the learning process. In comparison, distance education provides a learner with flexibility, individualized learning, lower costs, and self-determination in the learning process. Much research has been invested into modern approaches that may be able to harness key benefits from both face-to-face and distance education. One recent breakthrough has come in the use of asynchronous …

Holographic Recording In Acrylamide Photopolymers: Thickness Limitations, Mohammad Mahmud, Izabela Naydenova, Nitesh Pandey, Tzvetanka Babeva, Raghavendra Jallapuram, Suzanne Martin, Vincent Toal

Articles

Holographic recording in thick photopolymer layers is important for application in holographic data storage, volume holographic filters and correlators. Here, the characteristics of acrylamidebased photopolymer layers having thickness from 250 μm to 1-mm were studied. For each layer thickness samples with three different values of absorbance were studied. By measuring both the first order diffraction efficiency growth of holographically recorded gratings and studying the diffraction patterns obtained, the influence of scattering on the diffraction efficiency of thick volume holographic gratings was analyzed. It was observed that above a particular thickness and absorbance, the first order diffraction efficiency significantly decreased because …
