Rankings And The Global “Battle For Talent", Ellen Hazelkorn Jan 2009

Rankings And The Global “Battle For Talent", Ellen Hazelkorn

Books/Book chapters

This chapter will look at the impact that rankings are having on student choice and mobility, and the way in which both higher education institutions (HEIs) and government are responding to global competition for talent. It draws on the results of an international survey of HE leaders in 2006 and interviews with HEIs in Australia, Japan and Germany during 2008. The research was conducted under the auspices of the OECD Programme for Institutional Management of Higher Education, the International Association of Universities, and the Institute of Higher Education Policy—the latter with funding from the Lumina Foundation. There are three main …

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 …

Output Feedback Adaptive Control Of A Class Of Nonlinear Discrete-Time Systems With Unknown Control Directions, C Yang, Ss Ge, Th Lee Jan 2009

Output Feedback Adaptive Control Of A Class Of Nonlinear Discrete-Time Systems With Unknown Control Directions, C Yang, Ss Ge, Th Lee

School of Engineering, Computing and Mathematics

In this paper, output feedback adaptive control is investigated for a class of nonlinear systems in output-feedback form with unknown control gains. To construct output feedback control, the system is transformed into the form of the NARMA (nonlinear-auto-regressive-moving-average) model, based on which future output prediction is carried out. With employment of the predicted future output, a constructive output feedback adaptive control is given with the discrete Nussbaum gain exploited to overcome the difficulty due to unknown control directions. Under the global Lipschitz condition of the system functions, the boundedness of all the closed-loop signals and asymptotical output tracking are achieved …

When Is A Terrorist Not A Terrorist?: American And Chinese Media Portrayals Of The Chinese Uighur Minority Pre And Post 9/11, Anna File, '09 Jan 2009

When Is A Terrorist Not A Terrorist?: American And Chinese Media Portrayals Of The Chinese Uighur Minority Pre And Post 9/11, Anna File, '09

Honors Projects

Over the past sixty years the Uighur population in China has faced a variety of complex issues, both domestically and internationally. In large part due to their geopolitical positioning as inhabitants of Xinjiang Province as well owing to several issues with their Muslim faith, Uighurs have constantly been at odds with the Communist traditions imposed upon them by the central Chinese government. Not only do problems with their religion affect them nationally, but more recently with the trend towards suspicion of Muslim groups by Westerners, the Uighurs are in a seemingly helpless position. This paper hypothesizes however, that this has …

Explaining Ethnic Peace: The Importance Of Institutions, Rebecca Tong, '09 Jan 2009

Explaining Ethnic Peace: The Importance Of Institutions, Rebecca Tong, '09

Honors Projects

This paper examines the cause of ethnic peace, and subsequently, the cause of ethnic violence. Varying theories explain ethnic violence: primordialism, instrumentalism, and constructivism. The question central to this study is how master narratives, scarce resources, and democratic institutions have influenced the occurrence of ethnic violence. Small n comparison is used to analyze two pairs of sub-Saharan African nations in order to control for other explanatory variables: (1) Cote d'Ivoire and Ghana, and (2) Kenya and Tanzania. In each pair, one nation is relatively peaceful and the other relatively violent. Drawing from ethnographic research papers, and news sources this paper …

Experiencing Interaction Design: A Pragmatic Theory, Ronald Lengkong Wakkary Jan 2009

Experiencing Interaction Design: A Pragmatic Theory, Ronald Lengkong Wakkary

School of Engineering, Computing and Mathematics Theses

This thesis contributes a theory for the field of interaction design based on philosophical pragmatism. The theory frames interaction design as a pragmatic experience shaped by the inquiries of designers. The contributions of the theory are that it positions the designer at the centre of a theory, describes interaction design practice to be more than a collection of methods and strategies, and provides a sound basis for generating and verifying new knowledge through design. The thesis describes and analyzes two interaction design research projects through self-reflexive accounts that illustrate the proposed theory. The projects are a tangible museum guide and …

Acute Effects Of Self-Paced Walking On Smoking Withdrawal And Cravings, Magdalena Katomeri Jan 2009

Acute Effects Of Self-Paced Walking On Smoking Withdrawal And Cravings, Magdalena Katomeri

School of Psychology Theses

High relapse rates among smokers attempting to quit have been linked with failure to cope with cigarette cravings and withdrawal symptoms. Smoking cravings and withdrawal behavior is known to be influenced by stress and exposure to smoking cues. Exercise appears to reduce cigarette cravings and withdrawal symptoms. However no study has investigated the effects of exercise on cue-elicited cravings and withdrawal symptoms, or on ad libitum smoking behavior. Aim: Four experimental studies were designed to examine the effects of exercise on smoking behavior. Initial studies focused on the effects of a single session of brisk walk on cigarette cravings and …

Introduction: Approaches To Qualitative Research, John Hogan, Paddy Dolan, Paul Donnelly Jan 2009

Introduction: Approaches To Qualitative Research, John Hogan, Paddy Dolan, Paul Donnelly

Books/Book Chapters

Undertaking a dissertation can be a daunting prospect, irrespective of whether a student is an undergraduate or a postgraduate. The idea of having to start with a blank sheet of paper and finish with anything between 15,000 words for an undergraduate dissertation, and 100,000 words of a PhD dissertation, is an arresting thought. But, even these coarse figures fail to capture the true extent of the work involved, as a finished dissertation is usually only a distillation of volumes of work and words that far exceed the finished product ultimately presented. The various chapters present examples for dissertation students in …

Supreme Seafoods, Thomas Cooney

Case studies

Fintan Barrett’s four year old daughter would often turn to him while playing and exclaim “what to do, Daddy?” Indeed, this very question of what to do next had frequently swirled around his own head as he considered the options that were now available to him and his business Supreme Seafoods. Some commentators had described the recent economic crisis as ‘a perfect storm’ and that analogy was particularly apt for someone operating in the fish industry. Although Fintan’s family had worked in the fishing industry for many generations, whether out at sea or processing and selling fish on land, the …

Signs Of Access In A Digital World: Online Delivery Of Deaf Studies Curricula In Ireland At Third Level,, Brian Nolan, Lorraine Leeson Jan 2009

Signs Of Access In A Digital World: Online Delivery Of Deaf Studies Curricula In Ireland At Third Level,, Brian Nolan, Lorraine Leeson

Conference Papers

Irish Sign Language (ISL), an indigenous language of Ireland, is recognized by the European Union as a natural language. It is a language separate from the other languages used in Ireland, including English, Irish, and, in Northern Ireland, British Sign Language. Some 5,000 Deaf people use ISL. Given the history of suppression of signed languages across the EU, the average Deaf person leaves school with a reading age of 8.5 to 9 years. Given this, it is no surprise that Deaf people are the most under-represented of all disadvantaged groups at third level. This poses two challenges: (1) getting Deaf …

Preparation, Characterization Of Nipam And Nipam/Bam Copolymer Nanoparticles And Their Acute Toxicity Testing Using An Aquatic Test Battery, Pratap Naha, Alan Casey, Tiziana Tenuta, Iseult Lynch, Kenneth Dawson, Hugh Byrne, Maria Davoren

Articles

Poly N-isopropylacrylamide and N-isopropylacrylamide / N-tert-butylacrylamide copolymer nanoparticles of 50 to 70 nm were prepared by free radical polymerisation. The particle sizes of the copolymer nanoparticles were measured in the test media MilliQ water, Algae Media, Daphnia Media and Microtox Diluent as a function of temperature. Whereas in MilliQ water the particle size was seen to decrease above the lower critical solution temperature of the thermoresponsive polymer, in the test media it was seen to increase significantly, indicative of aggregation. At the temperatures employed for the ecotoxicological studies all particles, with the exception of the 50:50copolymer existed as nanoparticles, however. …

Integrating Learning Technologies With Experiential Learning In A Postgraduate Teacher Education Course, Roisin Donnelly Jan 2009

Integrating Learning Technologies With Experiential Learning In A Postgraduate Teacher Education Course, Roisin Donnelly

Journal Articles

This paper discusses how a Postgraduate Certificate Course in Third Level Learning and Teaching for academic staff in the Republic of Ireland has adopted a particular approach in teacher education. As an important aspect of the successful integration and use of learning technology is the way in which it effectively reflects and articulates a given learning model, this course has its theoretical basis on the Kolb Experiential Learning Cycle (Kolb, 1983). The work illustrates that no one technology can support all types of third level learning and teaching; an effective approach is to combine a range of technologies. The self-study …

Latter-Day Saint Children And Youth In America, David C. Dollahite Jan 2009

Latter-Day Saint Children And Youth In America, David C. Dollahite

Faculty Publications

Some of the concepts of the view of the childhood held by the Latter-day Saints can be found in stories told about the early life of their founder and first prophet, Joseph Smith. Brother Joseph, as he was known to the Saints, often took time to play games with children and youth. Some Mormons, with their early American sense of propriety about religious leaders, were troubled by Joseph's playful nature. One day a Brother Wakefield came to the Prophet's home to discuss church business. He was told that Brother Joseph was translating the word of God. Brother Wakefield waited some …

Articles

Verotoxigenic E. coli (VTEC) belong to a diverse range of serotypes. Serotypes O157 and O26 are predominately identified in VTEC-associated disease in Europe, however due to difficulty in detection little is known about the epidemiology of non-O157 serotypes. This study reports the identification of 7 VTEC serotypes from cattle faeces and soil. Cattle faeces samples (n = 128) were taken from animals in 6 different farms, with soil samples (n = 20) obtained from 1 farm. After sample incubation in modified tryptone soy broth (mTSB) supplemented with streptomycin sulphate samples were plated onto sorbitol MacConkey (SMAC) also supplemented …

Reflections Of A Layman On The Ryan Report, Eamon Maher

Books/Chapters

The Ryan Report on abuse of children in institutions of the state which were run by religious orders caused outrage and confusion among all the people of Ireland, both members of the Catholic Church and others. In the aftermath of the immediate shock and the widespread media coverage, it seems useful to reflect on the roots of the problems that gave rise to these horrors and to try to set out a way forward which might help to avoid such things happening in the future. Tony Flannery set about seeking views, comments and analysis which might add some breadth and …

Shear Class: A Visual Ethnography Of The British Hair Salon: Part Of Portfolio Kurl Up N Dye, I Rae

School of Art, Design and Architecture

In his book The Ongoing Moment, the English writer Geoff Dyer (2005) draws out some of the common themes that have concerned photographers over the last century. His focus is the documentary tradition, primarily American, and within it he notes the homage that younger photographers pay to the history of image making that has gone before them. Barbershops are one example. Tracing a lineage from Walker Evans through Robert Frank to Michael Ormerod, with a short detour by way of Diane Arbus, he notes the ways in which the barbershop has been a recurring motif, how different people have photographed …

Silver Doped Perfluoropolyether-Urethane Coatings: Antibacterial Activity And Surface Analysis, Niall Stobie, Brendan Duffy, Steven Hinder, Patrick Mchale, Declan Mccormack

Articles

The colonisation of clinical and industrial surfaces with pathogenic microorganisms has prompted increased research into the development of effective antibacterial and antifouling coatings. There is evidence that implanted biomedical surfaces coated with metallic silver can be inactivated by hysiological fluids, thus reducing the bioactivity of the coating. In this work, we report the biofilm inhibition of Staphylococcus epidermidis using a roomtemperatureprocessedsilver dopedperfluoropolyether-urethane coating. The release of silver ions from these fluoropolymers over a six-day period inhibited bacterial encrustation – as observed by scanning electron microscopy (SEM). X-ray photoelectron spectroscopy (XPS) analysis indicated differences in carbon, fluorine and sodium surface composition …

Improved Frequency Domain Channel Estimation And Equalization For Mimo Wireless Communications, Jian Zhang, Yahong Rosa Zheng Jan 2009

Improved Frequency Domain Channel Estimation And Equalization For Mimo Wireless Communications, Jian Zhang, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

This paper introduces an improved frequency domain channel estimation method based on interpolation vectors for single carrier frequency domain equalization (SC-FDE) with the multiple-input multiple-output (MIMO) scheme. the proposed algorithm is derived by employing the least squares (LS) criterion, and a specified application for the wide sense stationary uncorrelated scattering (WSSUS) Rayleigh fading channel is presented. the channel frequency domain responses estimated at two adjacent pilot blocks are used to track the time-variant channel information, which can effectively improve the accuracy of channel estimation without significantly increasing complexity. Maximum mean square error (MMSE) frequency domain equalization based on the estimated …

The Writer-Of-Violence-As-School-Shooter Stereotype: How Columbine, Virginia Tech, And Public Fear Make Writing Violence Dangerous For Students, Matt Foy

Dissertations and Theses @ UNI

In a period when students, parents, teachers and administrators are bombarded with images related to school shooting attacks, efforts to prevent such attacks in the future and to identify students who pose a threat to school safety have intensified. These efforts to fight the seemingly mounting wave of school violence have contributed to the rise of stereotypes of what a school shooter looks, talks, and acts like. This study examines one of these stereotypes: the writer-of-violence-as-school-shooter stereotype. This stereotype, which gained attention after 1990s rampages such as those at Heath High School (Kentucky) and Columbine High School and became highly …

Background/Purpose Assessing periodontal conditions has always been a concern for dental researchers. In this study, we evaluated the potential of a natural frequency (NF) analysis to detect the health status of natural human canine teeth. Materials and methods Three-dimensional finite element models of the human maxillary canine were constructed. NF values of the canine model were calculated with one-, two- and three-sided vertical bone loss. Results By simulating a modal testing experiment, the NF value for a healthy canine was found to be 2581 Hz. As the bone level was lowered, a strong linear relationship between the frequency and attachment …
