Measuring And Comparing Quantum Yield In Two Species Of Marine Diatoms Subjected To Constant And Fluctuating Light Conditions, Matthew Leon Stone

Master's Theses

A small-scale study was conducted to determine the effects of light fluctuations on the photosynthetic efficiency of marine phytoplankton. Two species, Phaeodactylum tricornutum and Chaetoceros gracile were grown in specialized photobioreactors on a 12-hour:12-hour light:dark cycle. The cultures were diluted 50% daily to attain a specific growth rate of 0.70 d-1. To simulate vertical mixing in high turbidity habitats under various wind conditions, dense cultures were subjected to fluctuating light treatments with frequencies ranging from 0.10 Hz to 2.00 Hz. Parallel experiments subjected the cultures to static light conditions with equal total daily light doses as those of the cultures …

Lead And Attention-Deficit/Hyperactivity Disorder: A Meta-Analysis, James Kenneth Goodlad Iii

Master's Theses

Attention-Deficit/Hyperactivity Disorder (ADHD) is thought to have a significant neurological component, and several brain structures have been implicated. Environmental variables like lead have been shown to affect brain structures, which in turn impacts cognitive development and behavior. Some studies have begun to associate environmental variables like lead with the inattentive and hyperactive-impulsive symptoms of ADHD. This meta-analysis examined the association between different components of ADHD (including attention problems and hyperactivity/impulsivity) and level of lead exposure in children and adolescents. Articles focusing on the association between lead and inattention or hyperactivity-impulsivity symptoms were gathered from the online databases PsycINFO and Medline. …

A Content Analysis Of Statutory Grounds For Involuntary Termination Of Parental Rights: The Impacts And Susceptibility Of Incarcerated Mothers And Their Children, Holly Marie Duke

Master's Theses

As the myriad of complex circumstances surrounding incarceration and foster care debilitate the parent-child relationship, the likelihood of legal severance between an incarcerated parent and their child increases. Despite the nation’s mounting prison population over the last three decades, the growing interaction between the prison and foster care populations has received minimal attention in the literature. To date, the influence of the statutory grounds for involuntary termination of parental rights on the legal severance between incarcerated parents and their children has been largely ignored. The purpose of this research is to determine the susceptibility of incarcerated parents to the involuntary …

Ancestral Analysis Of The French Colonial Moran Cemetery, Biloxi, Mississippi, Danielle Nicole Cook

Master's Theses

The Moran site (22HR511) in Biloxi, Mississippi, dates from 1719 to 1723 and is the earliest known French Colonial cemetery in the United States. Historical records suggest that those interred likely represent immigrants from Western Europe as well as Africa who were relocated in an effort to colonize the Louisiana Territory. Given the variety of cultural backgrounds at the site, an ancestral analysis of the 25 individuals uncovered has been conducted. Traditional markers such as cranial and tooth morphology and metrics, and enamel composition, were evaluated in all individuals, and DNA was analyzed in five. Stable isotope levels were also …

A Meta-Analysis Of Component Treatment Studies: Are The Parts As Good As The Whole?, Erin Jane Clarke

Master's Theses

Psychotherapy has been proven effective in treating a variety of mental health issues. However, there is disagreement in psychotherapy research about whether or not factors common to all psychotherapies or specific ingredients within a treatment package are responsible for successful treatment outcomes. Component studies are research designs specifically aimed at identifying the mechanisms of change in a full treatment package. Component studies do this by comparing the differences in outcome among dismantled treatment components and the full treatment protocol. The present metaanalytic review of component studies examined whether or not differences between these two treatment groups generally exist. Fifty-nine component …

Extreme Risks In Financial Markets And Monetary Policies Of The Euro-Candidates, Hubert Gabrisch, Lucjan T. Orlowski

WCBT Faculty Publications

This study investigates extreme tail risks in financial markets of the euro-candidate countries and their implications for monetary policies. Our empirical tests show the prevalence of extreme risks in the conditional volatility series of selected financial variables, that is, interbank rates, equity market indexes and exchange rates. We argue that excessive instability of key target and instrument variables should be mitigated by monetary policies. Central banks in these countries will be well-advised to use both standard and unorthodox (discretionary) tools of monetary policy while steering their economies out of the financial crisis and through the euro-convergence process.

Introduction To The Symposium On 'Financial Risks And Economic Stability In Emerging Market Economies', Lucjan Orlowski

WCBT Faculty Publications

Developing resilience to contagion effects from global financial crises and economic recessions has been an ongoing crucial task for policymakers in emerging market economies. The recent global financial crisis of 2007-2009 has underscored the importance of pursuing disciplined macroeconomic policies and of devising sound macroprudential regulations that would strengthen the immunity of emerging markets and their institutions to various types of risks, including credit, default, sovereign, liquidity and market risks. The studies included in this symposium are not intended to provide a comprehensive overview of financial vulnerabilities in a broad spectrum of emerging markets. Rather, they share a common aim …

Workplace Harassment: The Social Costs Of Bullying, Andra Gumbus, Bridget M. Lyons

This study uses content analysis to determine themes emerging from a writing assignment that asks students to respond to questions about workplace bullying. The intent of the research is to enable bullying targets to better understand the situation, to help managers to learn how to mitigate possible bullying situations, and to assist witnesses to better react to workplace incidents.

A Network Based Theory Of Foreign Market Entry Mode And Post-Entry Performance, Jing'an Tang, Ben S. Liu

WCBT Faculty Publications

Foreign market entry through equity investment has been extensively studied and various theoretical lenses have been used. Most previous research also focuses attention on either the entry mode selection decision or the topic of post-entry performance, but rarely both. We build on existing research by developing a model of foreign market entry and post-entry performance that uses network theory and organizational ecology to provide a fuller explanation of this complex and critical multinational enterprise strategic behaviour. Four pairs of total eight propositions were developed and justified based on extent literature and sound logical reasoning. By focusing on both entry mode …

Management Of Records In University Libraries In The South-South Zone Of Nigeria, Blessing Amina Akporhonor

Library Philosophy and Practice (e-journal)

Universities the world over are centres for academic pursuits as well as place where learning is sought at its maximum level. A university library, be it federal or state owned, is part of a university set up. Accordingly, it seeks to advance the functions of the institution (Kumar, 1987) by generating and transacting information in form of records for teaching, learning, research and for administration in the course of its daily activities (Akporhonor and Iwhiwhu, 2007). In other words, records are created and used in the operation of a university and its library. For a university library to function effectively …

A Private Library With Valuable Intellectual And Cultural Heritage: A Case Of Masood Jhandeer Research Library, Farzana Shafique, Ata-Ur- Rehman, Sarwat Mukhtar

Library Philosophy and Practice (e-journal)

Introduction

The literature on the history of libraries indicates that the mechanism of recording the human communication and its preservation was the first step towards the manifestation of libraries. The collections consisted of clay tablets, papyrus roll, and codices were created and housed with great care in rooms adjacent to temples. The aim of writing was to preserve sacred human communication and knowledge (Ameen, 2005, p.112). From antiquity, rulers have controlled knowledge in order to establish social, religious, cultural, and political power. Their private libraries served as archives that held documents of royal families, genealogical charts, private medical records, military …

The Library As An Effective Tool For Understanding The Health Status Of Rural Communities In Nigeria, Nnenna A. Obidike, Idoko Nkechi

Library Philosophy and Practice (e-journal)

Library in any community is regarded as an information base centre for storage and retrieval of vital information which could be used for community development and national planning. The library is the gateway to information (Anasi, 2010). It is a place where information is acquired, processed, repackaged, preserved and disseminated. Every community (country) aims at improving the health of its citizens and plan outreach annually (Ogunbode, 2004). This objective would be better achieved where libraries are seen as effective tools for understanding the health status of rural communities in Nigeria. Librarians are meant to partner with community health workers to …

Auto-Tuning Antenna, John Chen, Jennifer Tighe

Electrical Engineering

Radio transmitters and antennas have differing impedances at the output and feedpoint, depending on frequency. Modern antenna tuning methods involve manual or automatic resistance and reactance network adjustment to match transmitter and antenna impedance. This reduces power reflections to the transmitter, but introduces losses and prevents full transmitter power from being radiated at the antenna. This project utilizes a variable length antenna element to tune and match transmitter and antenna impedances, allowing efficient power transfer to the antenna. The antenna length varies from 0 to 30.5 inches. The method involves an RF signal with a maximum power of 2 watts …

Analyzing The Construction Of The Medical Professional Identity: How Do Doctors Learn To "Do Doctoring?", Lauren Dougall

Honors Program Theses

This study is a qualitative analysis of how primary care physicians within the first five years of practice after residency construct their medical professional identity. An open-ended interview schedule was used to collect data which revealed the main themes of observational learning, dealing with uncertainty, and the importance of communication and education in patient interaction. Each doctor's professional identity was ultimately a refined version of the image they attributed to doctors as a lay-person.

The Influence Of Peer Tutors And Technology-Actuated Reading Instruction Process On Third-Grade Students' Self-Perceptions As Readers: A Multiple Case Study, Brenda Shill Daw

UNLV Theses, Dissertations, Professional Papers, and Capstones

Driven by Lev Vygotsky's Sociocultural Theory (1986), my study investigated the self-perceptions and interactions of seven underperforming, third-grade readers while using Technology-Actuated Reading Instruction (TARI). Partnered with same-age peer tutors, readers used digital tools to listen to, read/record, and playback oral reading passages. They practiced, peer- or self-edited, and selected their best reading products as part of the iterative process. As reading is a complex cognitive skill (Reinking, 2005), TARI incorporated higher cognitive learning activities via a synthesis of Gagné's (1985) nine conditions of learning and the Four-Component Instructional Design Model (van Merriënboer & Kester, 2005).

Effect Of Toothbrush Abrasion On Frictional Resistance Of Aesthetic Orthodontic Archwires, Stephen Alexander Yamodis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fixed orthodontic appliances (braces) are one of the most widely used appliances to correct malocclusion, however many patients prefer less metal display. To meet this demand more esthetically pleasing brackets and archwires have been developed. These esthetic components are often clear, white or tooth colored. Coatings of various types are commonly used to produce an esthetic archwire. However, these coating materials tend to wear and degrade, which may cause binding and increased resistance to friction, thereby potentially reducing the efficiency of tooth movement. Therefore, in vitro testing of tooth brush abrasion on frictional resistance of various aesthetic archwires was tested. …

Rotating Algal Biofilm Reactors: Mathematical Modeling And Lipid Production, Paul A. Woolsey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Harvesting of algal biomass presents a large barrier to the success of biofuels made from algae feedstock. Small cell sizes coupled with dilute concentrations of biomass in lagoon systems make separation an expensive and energy intense-process. The rotating algal biofilm reactor (RABR) has been developed at USU to provide a sustainable technology solution to this issue. Algae cells grown as a biofilm are concentrated in one location for ease of harvesting of high density biomass. A mathematical model of this biofilm system was developed based on data generated from three pilot scale reactors at the City of Logan, Utah wastewater …
