Impact Of Remedial Reading Interventions On A Secondary Student With Emotional Behavior Disorder: A Case Study, Lucinda Cooper

Doctoral Dissertations and Projects

Students who struggle with emotional behavior disorders (EBD) often enter high school with reading levels far below those of their peers. At the secondary level, these at-risk students must regularly read and write proficiently in order to demonstrate their literacy achievement and potential for success either in college or on the job. As a result, many EBD students choose to drop out of school instead of daily feeling that they do not measure up. This instrumental qualitative case study examined the impact of the five essential components of reading instruction, teacher modeling, repeated readings, and progress monitoring on the disruptive …

Shelf Life Study Of Electrospun Plga Copolymers, Sean Youra, Nick Hudson

Biomedical Engineering

Poly(lactic-co-glycolic acid) (PLGA) is one of the most commonly used copolymers for electrospinning in tissue engineering applications. However, most research has not focused on the copolymer itself in regards to how long it can be used effectively and if varying the concentrations of polylactic acid (PLA) and polyglycolic acid (PGA) affect the resulting properties. Electrospinning is the method we use to create the three-dimensional constructs, or “scaffolds”, for the blood vessel mimic (BVM) in the tissue engineering lab. The aim of our project was to investigate if the morphology and mechanical properties of the scaffolds changed over time when they …

Analysis Of Acetabular Cup Orientation Effects On Stress Shielding In Total Hip Replacements Using Finite Element Methods, Brogan Mcguire, Jennifer Gemkow, Brad Gausewitz, Alex Georges

Biomedical Engineering

Improper positioning of the acetabular cup has been shown to contribute to issues such as high wear rates and dislocations in total hip replacements. The differences in contact mechanics due to varying orientation of the acetabular cup may also significantly affect strain distribution in the femur. This study examined these effects of acetabular orientation changes and their contribution to stress shielding using finite element analysis. A solid model of a cementless total hip implant was obtained using 3D point scanning and implanted virtually into a femur solid model. The implanted femur model was imported into ABAQUS and loaded with a …

Effect Of Oral Lipids On Blood Glucose, Tyler R. Knisley

Biomedical Engineering

Diabetes mellitus is a disease in which insulin hormone is ineffective or no longer produced. Multiple pathophysiologies can cause either insulin dependent diabetes mellitus (IDDM) or insulin independent diabetes mellitus (IIDM), which can lead to chronic hyperglycemia and an array of short and long term health risks. Prior research has shown that IDDM patients have dyslipidemia, and experiments infusing lipids directly into the blood result in heightened insulin resistance. The hypothesis that dyslipidemia increases insulin resistance was tested by performing oral glucose tolerance tests across three treatment conditions. Participants were nondiabetic college-aged students. Data from a control group was gathered …

A Mouse Model Of Aortic Endothelial Denudation And Neointimal Formation, Ashkon C. Nehzati

Biomedical Engineering

More than 385,000 people die from coronary heart disease (CHD) annually and treatment costs $108.9 billion each year including the cost of health care services, medications, and lost productivity. CHD decreases heart function by limiting oxygen and nutrient transport carried through the coronary arteries. A complete block to the coronary arteries causes a myocardial infarction in response to an elimination of blood supply to cardiomyocytes. Partial occlusion results in insufficient blood supply to cardiomyocytes, producing myocardial ischemia and angina, which are usually treated with intravascular stents deployed percutaneously, before myocardial infarction occurs. Stents are the most common ways to expand …

Affect As A Decision-Making System Of The Present, Hannah H. Chang, Michel Tuan Pham

Research Collection Lee Kong Chian School Of Business

We review a variety of empirical findings consistent with the general thesis that the affective system of judgment and decision making is inherently anchored in the present. Building on this thesis, we advance the specific hypothesis that affective feelings are relied upon more (weighted more heavily) in judgments whose outcomes and targets are closer to the present than in those whose outcomes and targets are temporally more distant. Consistent with this hypothesis, results from five experiments show that temporal proximity (a) amplifies the relative preference for options that are affectively superior, and (b) increases the effects of incidental affect on …

Quantitative analyses conducted between male and female …

Negotiating Marital Care: Co-Creating The Connected Egalitarian Relationship, Lena Lopez Bradley

Loma Linda University Electronic Theses, Dissertations & Projects

Research suggests that couples seek connection and equality within the marital relationship, yet they continue to struggle due to the continued impact of traditional gender ideologies (Coontz, 2006; Knudson-Martin & Mahoney 2009). The current body of literature reveals little about how specific relational negotiation practices contribute to attaining an equal and connected relationship over time. This study utilizes grounded theory methodology and a feminist social constructionist framework to explore how traditional gender constructs impact couples’ ability to negotiate connected egalitarianism within relationship over time.

The analysis of 68 interviews with two sets of couples—parents of children 5 years old and …

Enhancement Of The Phytochemical And Fibre Content Of Beef-Patties With Himanthalia Elongata Seaweed, Sabrina Cox, Nissreen Abu-Ghannam

Articles

The effect of adding Himanthalia elongata seaweed (10 - 40% w/w) as a source of antioxidants and dietary fibre on physical, chemical, microbial and sensory traits of cooked beef patties was studied throughout chilled storage. Patties with seaweed showed reduced cooking losses and were nearly 50% more tender as compared to patties without seaweed. Microbiological counts and lipid oxidation were significantly lower in patties containing seaweed (P < 0.05), by day 30 of storage there was no bacterial growth in samples with ≥ 20% seaweed and lipid oxidation levels were low (0.61 mg malondialdehyde/kg of sample). Seaweed incorporation significantly increased the dietary fibre (1.64 g per 100 g fw in 40% seaweed-patties), total phenolic content (up to 28.11 mg GAE/100 g fw) and DPPH radical scavenging activity (up to 52.32%) of patties compared to the control. Sensory analysis indicated that the seaweed-patties were accepted by consumers in terms of aroma, appearance, texture and taste. Patties containing 40% seaweed were rated highest in terms of overall acceptability, most likely due to improvement in texture and mouthfeel. Addition of seaweed in the formulation of beef patties leads to the enhancement of the nutritional and technological quality together with an acceptable sensory quality.

Incorporation Of Himanthalia Elongata Seaweed To Enhance The Phytochemical Content Of Breadsticks Using Response Surface Methodology (Rsm), Sabrina Cox, Nissreen Abu-Ghannam

Articles

Optimization of incorporating seaweed into breadsticks was carried out using response surface methodology (RSM). Ten formulations of breadsticks were processed by varying concentrations of seaweed (X₁ = 5 to 15% of overall flour concentration) and white flour (X₂ = 10 to 30% of overall flour concentration) using a central composite design. The remaining flour concentrations were comprised of wholemeal flour. Predicted models were found to be significant (P < 0.05) for total phenolic content (TPC), DPPH radical scavenging activity, texture and color. Predicted values for each of the responses were in good agreement with the experimental values. Seaweed concentration had most significant effect on phytochemical constituents of the breadsticks with TPC and DPPH activity maximized when 17.07% H. elongata was incorporated into the flour (P < 0.05). An acceptable edible texture and color of breadsticks was also achieved at this concentration. Multiple response optimization demonstrated that phytochemical content of H. elongata breadsticks may be maximized with dried seaweed and white flour concentrations of 17.07 and 21.89%, respectively, in the …

Gsx2 Controls Region-Specific Activation Of Neural Stem Cells And Injury-Induced Neurogenesis In The Adult Subventricular Zone, Alejandro Lopez-Juarez, Jennifer Howard, Kristy Ullom, Lindsey Howard, Andrew Grande

Health & Biomedical Sciences Faculty Publications

Neural stem cells (NSCs) reside in widespread regions along the lateral ventricle and generate diverse olfactory bulb (OB) interneuron subtypes in the adult mouse brain. Molecular mechanisms underlying their regional diversity, however, are not well understood. Here we show that the homeodomain transcription factor Gsx2 plays a crucial role in the region-specific control of adult NSCs in both persistent and injury-induced neurogenesis. In the intact brain, Gsx2 is expressed in a regionally restricted subset of NSCs and promotes the activation and lineage progression of stem cells, thereby controlling the production of selective OB neuron subtypes. Moreover, Gsx2 is ectopically induced …

Treading Water While Congress Ignores The Nation's Environment, Sandra B. Zellmer

Faculty Law Review Articles

During the late 1960s, the nation's attention was riveted on graphic images of contaminated resources, such as smoldering rivers and oil-soaked seagulls,' as well as Rachel Carson's haunting prose about the "strange blight"2 of chemical pesticides afflicting land, water, and wildlife. Policymakers recognized the need for strong legal protections for public health and the environment, and Congress responded with sweeping legislation governing the pollution of water, air, and soil, and the demise of threatened and endangered species.3

The Clean Water Act of 1972 (CWA), which regulates discharges of pollutants into waters of the United States, is one of the most …

Comparative Pedestrian Visibility Under Solid State Led Sources, Dana Younis

Theses

One of the important factors in striving towards sustainable urban living is the safety of pedestrians. This safety is influence by many factors, one of which is the ability of drivers to see pedestrians. During the night, pedestrian visibility becomes more difficult, especially on two-way streets, where headlamps of cars from the opposite direction cause glare to drivers. Newer types of headlamps are using LEDs and Xenon which are glarier than older halogen types.

This study is arranged in two parts. The first part of which examines the effect of oncoming car headlamps on pedestrian night time visibility. Detection distance …

It is rare to have the opportunity to write a theory paper on a topic that, we believe at least, will become a very important part of psychological research in the future. That this target article has sparked such a high level of sophistication in the commentaries is indicative of this possibility; psychologists have truly arrived at the forefront of the social class discussion, and we are very excited to be a part of it! In the spirit of moving forward this discussion, each of the commentaries raises a number of important points that intersect with our own theory. Engaging …

Dynamic Optimization Of Caregiver Schedules Based On Vital Sign Streams, Mohamed Saad, Bilal Khan

Publications and Research

Hospital facilities use a collection of heterogeneous devices, produced by many different vendors, to monitor the state of patient vital signs. The limited interoperability of current devices makes it difficult to synthesize multivariate moni- toring data into a unified array of real-time information regarding the patients state. Without an infrastructure for the integrated evaluation, display, and storage of vital sign data, one cannot adequately ensure that the assignment of care- givers to patients reflects the relative urgency of patient needs. This is an especially serious issue in critical care units (CCUs). We present a formal mathematical model of an operational …

Research Collection School Of Computing and Information Systems

Nowadays, big cities are suffering from severe traffic congestion as a result of the continuing increase in vehicles. Taxis equipped with GPS can be viewed as sensors of the traffic situation in city. However, trajectory data generated by taxi’s GPS traces are often high-dimensional and contain large spatial and temporal attributes, which pose challenges for analysts. In this paper, based on taxi trajectory data, we present an interactive visual analytics system, T-Watcher, for monitoring and analyzing complex traffic situations in big cities. Users are able to use a carefully designed interface to monitor and inspect data interactively from three levels …

Distributed Multichannel Speech Enhancement Based On Perceptually-Motivated Bayesian Estimators Of The Spectral Amplitude, Marek B. Trawicki, Michael T. Johnson

Electrical and Computer Engineering Faculty Research and Publications

In this study, the authors propose multichannel weighted Euclidean (WE) and weighted cosh (WCOSH) cost function estimators for speech enhancement in the distributed microphone scenario. The goal of the work is to illustrate the advantages of utilising additional microphones and modified cost functions for improving signal-to-noise ratio (SNR) and segmental SNR (SSNR) along with log-likelihood ratio (LLR) and perceptual evaluation of speech quality (PESQ) objective metrics over the corresponding single-channel baseline estimators. As with their single-channel counterparts, the perceptually-motivated multichannel WE and WCOSH estimators are functions of a weighting law parameter, which influences attention of the noisy spectral amplitude through …

High Oral Communication Apprehensives: How Can Students Be Helped To Reduce Their Fear Of Public Speaking?, Dan Shanahan

Irish Journal of Academic Practice

The literature has identified oral communication as a skill that employers desire of their workforce. Even though accounting and business education programmes place considerable emphasis on the advancement of communication competencies among students, not all students appear to benefit from communication skills development. This may arise from of a fear of communicating with others, commonly known as oral communication apprehension, a factor which inhibits an individual’s willingness to communicate in one or a number of contexts - one to one conversations, communicating in groups, at meetings and making a presentation in public – and which may inhibit development of effective …

While more constrained in its scopes-the iCub world is essentially a robotics research lab-we demonstrate how the proposed data-set poses challenges to current recognition systems. The iCubWorld data-set is publicly available © 2013 IEEE.

Raman Spectroscopic Analysis Of Human Skin Tissue Sections Ex-Vivo: Evaluation Of The Effects Of Tissue Processing And Dewaxing, Syed Mehmood Ali, Franck Bonnier, Ali Tfayli, Helen Lambkin, Kathleen Flynn, Vincent Mcdonagh, Claragh Healy, Thomas Lee, Fiona Lyng, Hugh Byrne

Articles

Raman spectroscopy coupled with K-means clustering analysis (KMCA) is employed to elucidate the biochemical structure of human skin tissue sections, and the effects of tissue processing. Both hand and thigh sections of human cadavers were analysed in their unprocessed and formalin fixed paraffin processed (FFPP) and subsequently dewaxed forms. In unprocessed sections, KMCA reveals clear differentiation of the stratum corneum, intermediate underlying epithelium and dermal layers for sections from both anatomical sites. The stratum corneum is seen to be relatively rich in lipidic content; the spectrum of the subjacent layers is strongly influenced by the presence of melanin, while that …

Preventing Deer Damage To Your Trees And Shrubs, Megan Schwender, Michael R. Kuhns

All Current Publications

Deer/human conflicts have increased due to growing deer populations, limited resources and suburban development in deer habitat. In winter, deer often browse in residential landscapes. This can be reduced by selecting unpalatable plants, protecting woody plants with burlap or trunk protectors, and using deer repellent. In extreme cases, deer can be completely excluded with a fence.

Breast cancer is the most common cancer seen in women worldwide accounting for more than 1.3 million cases and 458 000 deaths a year worldwide. Breast cancer patients are at high risk of recurrence in the form of metastatic disease. Genes associated with invasion and metastasis provides an aggressive edge in proliferation and growth during colonization of the metastatic site. The SMARCAD1 (SWI/SNF-related, Matrix-associated, Actin-dependent Regulator of Chromatin, containing DEAD/H box 1) protein is the human homolog of yeast Fun30 (Function Unknown Now 30) proteins. These proteins are members of the Snf2 helicase motif-containing protein families, and are known to …

Approximate Inference In Collective Graphical Models, Daniel Sheldon, Tao Sun, Akshat Kumar, Thomas G. Dietterich

Research Collection School Of Computing and Information Systems

We study the problem of approximate inference in collective graphical models (CGMs), which were recently introduced to model the problem of learning and inference with noisy aggregate observations. We first analyze the complexity of inference in CGMs: unlike inference in conventional graphical models, exact inference in CGMs is NP-hard even for tree-structured models. We then develop a tractable convex approximation to the NP-hard MAP inference problem in CGMs, and show how to use MAP inference for approximate marginal inference within the EM framework. We demonstrate empirically that these approximation techniques can reduce the computational cost of inference by two orders …
