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 …

Design, Manufacture, Mechanical Testing And Numerical Modelling Of An Asymmetric Composite Crossbow Limb, Amandeep S. Virk, J. Summerscales, W. Hall, S. M. Grove, M. E. Miles

School of Engineering, Computing and Mathematics

This paper considers the design, manufacture, mechanical testing and numerical analysis of a crossbow beam (limb). The limb should be lightweight and permit a high deflection of the beam's tip in order to achieve a good ballistic performance. Consequently, fibre-reinforced polymer matrix composites are suitable candidate materials. However, carbon fibres were considered too brittle for this application. Aramid fibres combine low density and high stiffness but are weak in compression. E-glass fibres are relatively flexible but are of high density. The optimised design developed here uses aramid fibres on the tension face with E-glass fibres on the compression side. This …

The Effects Of Different Types Of Background Music On Preschoolers’ Aggressive Classroom Behavior, Marissa Anne Arnett

Dissertations and Theses @ UNI

Previous research has suggested that background music influences children's classroom behaviors. However, the results of research to date are conflicting on the effects of hard rock background music on children's behavior. Thus, the purpose of the present study was to examine the differential effects of hard rock and easy listening music on preschoolers' aggressive behaviors during center time (e.g., during free play at the water table, art, blocks, and reading centers). Four classrooms with a combined total of 74 students (31 boys and 43 girls) participated in the study. During the 55-day study, we recorded the frequency of children's aggressive …

A Comparison Of Teachers’ Attitudes Toward Sexual Minority Students And Issues In Schools With And Without Gay Straight Alliances, Kelli Ranae Otis Brus

Dissertations and Theses @ UNI

The purpose of this study was to investigate teachers' attitudes toward sexual minority students (including lesbian, gay, bisexual, transgender, and questioning students) and issues related to this population of students. A sample of 166 high school teachers from schools with and without gay-straight alliances (GSAs) were compared on several measures to determine if teachers from schools with GSAs were significantly more supportive toward sexual minority students and issues than teachers in schools without GSAs .. Participants completed research packets containing the Professional Attitude Index Scale (PAIS) (Sears, 1992), a hypothetical situation of homophobia in a classroom for participants to provide …

When Networks Matter : Mexican Migrants' Access To The Welfare State Through Social Ties, Margaret Louise Ralston

Dissertations and Theses @ UNI

In this thesis, I examine the relationship between social networks among Mexican migrants and usage of welfare benefits. For this research, I use the Mexican Migration Project (MMP) dataset and logistic regression to assess whether social capital plays a significant role in connecting individuals to information and resources that affect their access to public systems of social protection, including welfare benefits. Recent welfare reform legislation has made it increasingly difficult for noncitizens to access the welfare state. Following the work of Massey and Aguilera (2003), I have conceptualized social capital as respondents' connection to their U.S. community and their ties …

Earth's Heat Source -- The Sun, Oliver Manuel

Chemistry Faculty Research & Creative Works

The Sun encompasses planet Earth, supplies the heat that warms it, and even shakes it. The United Nation's Intergovernmental Panel on Climate Change (IPCC) assumed that solar influence on Earth's climate is limited to changes in solar irradiance and adopted the consensus opinion of a hydrogen-filled Sun - the Standard Solar Model (SSM). They did not consider the alternative solar model and instead adopted another consensus opinion: Anthropogenic greenhouse gases play a dominant role in climate change. The SSM fails to explain the solar wind, solar cycles, and the empirical link of solar surface activity with Earth's changing climate. The …

Improving The Video Imaging Prediction Of Postsurgical Facial Profiles With An Artificial Neural Network, Chien-Hsun Lu, Ellen Wen-Ching Ko, Li Liu

Journal of Dental Sciences

Background/purpose With advancements in computer technology, postsurgical video image simulations are becoming more frequently used in orthognathic surgery. Simulations can greatly affect decision making by patients and also provide information to surgeons and orthodontists. However, most of the current commercial video image prediction software is only suitable for patient education but is not precise enough for clinical communication and treatment planning. The purpose of this study was to evaluate and improve post-orthognathic surgery image predictions. Materials and methods In this retrospective study, 30 bimaxillary protrusion patients who underwent two jaw surgeries were recruited. Simulations were compared with the actual postsurgical …

Delayed Formation Of Multiple Supernumerary Teeth, Yai-Tin Lin, Sung-Wen Chang, Yng-Tzer J. Lin

Journal of Dental Sciences

Multiple supernumerary teeth in either the maxillary anterior or premolar region can cause uneruption or impaction of the succedaneous permanent teeth. Supernumerary premolars are special in terms of their late development and recurrence. This case report details the use of multiple phases of orthodontic traction in order to obtain ideal clinical results. An 8-year 4-month-old healthy boy had an impacted left upper central incisor and multiple supernumerary teeth among the incisors and premolars. The impacted incisor was successfully moved to its proper position by orthodontic traction and a closed eruption technique. One year later, surgical extraction of three supernumerary premolars …

Grounding Terrorism on Ground Zero: How 9/11 Informs U.S. Press Coverage of Political Violence by Kevin Mack

This study analyzes the breaking news coverage of the United States press during the November 2008 Mumbai terrorist attacks. Previously, scholars such as Robert Entman and Elisabeth Anker found that U.S. media melodramatically framed the September 11, 2001 attacks and constructed a “War on Terror” ideology. Working from that theoretical perspective, the author posits this ideology influenced U.S. reporters and their style of reportage about the Mumbai attacks, as did breaking news characteristics and general patterns within journalism, …

Distributed Utility-Based Rate Adaptation Protocols For Prioritized, Quasi-Elastic Flows, Sharanya Eswaran, Matthew P. Johnson, Archan Misra, Thomas La Porta

Research Collection School Of Computing and Information Systems

This paper considers rate adaptation for streaming multimedia data in a wireless sensor network (WSN) consisting of multiple missions, where each mission subscribes to data streams from multiple sensors, and each sensor's data is utilized by multiple heterogenous missions. We specifically consider the application of the distributed network utility maximization (NUM) framework to a previously unconsidered scenario where the different missions have different priorities, as well as minimum utility demands. When all the utility demands are feasible, we first show that the addition of a penalty for failing to reach the minimum utility demand to the base NUM protocol leads …

Structural Basis For Binding Specificity Between Subclasses Of Modular Polyketide Synthase Docking Domains, Tonia Buchholz, Todd W. Geders, Frank E. Bartley Iii, Kevin A. Reynolds, Janet L. Smith, David H. Sherman

Chemistry Faculty Publications and Presentations

Bacterial type I polyketide synthases (PKSs) assemble structurally diverse natural products of significant clinical value from simple metabolic building blocks. The synthesis of these compounds occurs in a processive fashion along a large multiprotein complex. Transfer of the acyl intermediate across interpolypeptide junctions is mediated, at least in large part, by N- and C-terminal docking domains. We report here a comprehensive analysis of the binding affinity and selectivity for the complete set of discrete docking domain pairs in the pikromycin and erythromycin PKS systems. Despite disconnection from their parent module, each cognate pair of docking domains retained exquisite binding selectivity. …

Dab Eureka-147: The European Platform For Digital Radio, Brian O'Neill

Articles

Like its analogue counterpart, digital radio is one of the 'older' forms of new media. The technology of digital radio broadcasting has been under active development for at least 25 years and has produced a number of different technical solutions, the longest established of which is Eureka-147 or Digital Audio Broadcasting (DAB). This article explores DAB's distinctly European vision for the future of broadcasting. DAB is traced to its origins in 1980s European research and development policy and its affinity with traditions of European public service broadcasting. Ironically, it was DAB's failure to capitalize on its 'Europeanness' that contributed to …

Gender Differences In Children’S Internet Use:Key Findings From Europe, Helen Mcquillan, Brian O'Neill

Articles

This paper analyses comparative empirical data from across Europe on gender differences in children’s internet use, and through a new interpretive framework on young people’s experiences, seeks to add new findings to this growing international knowledge base. Linking feminist theory on gender and technology with theories of youth gender identity construction, four key areas are investigated. Firstly, the impact of increased internet access and use in schools and in homes on gender equality is examined. Secondly, youth communication and content creation practices are investigated to explore whether the internet is facilitating flexibility in gender identity and the transcendence of traditional …

A Chemical Ionization Mass Spectrometer For Continuous Underway Shipboard Analysis Of Dimethylsulfide In Near-Surface Seawater, Eric S. Saltzman, Warren J. De Bruyn, M. J. Lawler, Christa Marandino, C. A. Mccormick

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

A compact, low-cost atmospheric pressure, chemical ionization mass spectrometer ('mini-CIMS') has been developed for continuous underway shipboard measurements of dimethylsulfide (DMS) in seawater. The instrument was used to analyze DMS in air equilibrated with flowing seawater across a porous Teflon membrane equilibrator. The equilibrated gas stream was diluted with air containing an isotopically-labeled internal standard. DMS is ionized at atmospheric pressure via proton transfer from water vapor, then declustered, mass filtered via quadrupole mass spectrometry, and detected with an electron multiplier. The instrument described here is based on a low-cost residual gas analyzer (Stanford Research Systems), which has been modified …

Efficacy Of A Behavioral Intervention To Decrease Medication Transcription Errors Among Professional Nurses, Kathleen Ann Becker

Dissertations (1934 -)

The purpose of this study, guided by Donabedian's structure-process-outcome model, was to evaluate if a cognitive-behavioral education intervention would decrease medication transcription errors among professional nurses when admitting patients 65 years of age or older on 5 or more prescribed medications to a hospital. The conceptual framework for this study is derived from Donabedian's structure-process-outcome health model. The premise suggests improving the structure or process of a system can improve health outcomes. My intervention (cognitive behavioral education), specifically influences the process of medication history obtainment which improved medication error score. In this study, a randomized intervention design was used where …

Understanding Relationships In Health Related Quality Of Life For Parents Of Children With Autism Spectrum Disorder, Norah Louise Johnson

Dissertations (1934 -)

Nurses encounter many parents of children with autism spectrum disorder (ASD). Both parents are under stress that ultimately impacts their health related quality of life (HRQL). Few studies assess the mediators of parenting stress on HRQL for both parents. This study explored the relationship of parenting stress, family functioning and HRQL for parenting dyads of children with ASD. Lazarus and Folkman's (1984) Transactional Model of Stress and Coping and Lakey and Cohen's (2000) Social Support Theory framed the study.

Implementing a cross sectional, descriptive design, 387 parents (n=64 dyads) of ASD-affected children, from 46 states, completed web-based surveys. Demographics, the …

Surviving On Remand: A Study Of How Young People Cope In Remand Custody In Ireland, Sinead Freeman

Doctoral

The fusion of young people to the prison setting has been described as a toxic combination. This is especially pertinent when applied to youth in remand custody. Previous research studies have identified young people on remand as a highly vulnerable prison population and custodial remand to be a particularly stressful prison experience. Despite this, little research to date has examined how young people cope while remanded in custody. This thesis addresses this gap by providing an insight into the issue of coping on remand through the voices of young people in custody in the Irish context. It is informed by …

A Photochemically Initiated Chemistry For Coupling Underivatized Carbohydrates To Gold Nanoparticles, Xin Wang, Olof Ramström, Mingdi Yan

Chemistry Faculty Publications and Presentations

The sensitive optoelectronic properties of metal nanoparticles make nanoparticle-based materials a powerful tool to study fundamental biorecognition processes. Here we present a new and versatile method for coupling underivatized carbohydrates to gold nanoparticles (Au NPs) via the photochemically induced reaction of perfluorophenylazide (PFPA). A one-pot procedure was developed where Au NPs were synthesized and functionalized with PFPA by a ligand-exchange reaction. Carbohydrates were subsequently immobilized on the NPs by a fast light activation. The coupling reaction was efficient, resulting in high coupling yield as well as high ligand surface coverage. A colorimetric system based on the carbohydrate-modified Au NPs was …

Evaluating Ground Truth For Adress As A Preprocess For Automatic Musical Instrument Identification, Joseph Mckay, Mikel Gainza, Dan Barry

Conference papers

Most research in musical instrument identification has focused on labeling isolated samples or solo phrases. A robust instrument identification system capable of dealing with polytimbral recordings of instruments remains a necessity in music information retrieval. Experiments are described which evaluate the ground truth of ADRess as a sound source separation technique used as a preprocess to automatic musical instrument identification. The ground truth experiments are based on a number of basic acoustic features, while using a Gaussian Mixture Model as the classification algorithm. Using all 44 acoustic feature dimensions, successful identification rates are achieved.

Supporting Value Creation By Reducing Cultural Distance As A Barrier To Exporting, Thomas Cooney, Amanda Ratcliffe, Jane Silver

Articles

Value creation at the level of the organisation involves balancing the interests of several different stakeholders, with exporting occasionally viewed as a broad-based strategy capable of achieving such equilibrium. However, while much has been written concerning the logistical and economic challenges faced by SMEs wishing to avail of market opportunities abroad, there remains a dearth of information offering solutions to overcoming cultural distance as a barrier to exporting. An EU project entitled ‘Passport to Trade’ sought to provide greater insight into business culture by collating the customs and subjective norms of all member states within the EU and making the …
