Can Overeating Induce A Conditioned Taste Avoidance In Previously Restricted Rats?, Amanda Louise Hertel

Theses and Dissertations (Comprehensive)

While feeding is rewarding, the feeling of satiation has been theorized to be aversive under certain conditions. Using a food-restriction model of overeating developed in our laboratory the results presented here suggest that overeating, and the resulting experience of satiation, is capable of supporting a conditioned taste avoidance.

Rats had either ad lib (n=8) or restricted (n=24) food access (receiving 50% of the food eaten by ad lib fed rats) for 8 days. All rats were then given 24 hr access to a 0.1% saccharin solution, and two groups of food-restricted rats were given access to either 100% of the …

Simulation Studies On Estimation Of Variance Components For Multilevel Models, Sara Vakilian

Theses and Dissertations (Comprehensive)

With the presence of unequal sampling in a multilevel model, the weight inflated estimators for variance components can be biased even though the use of survey weights results in design consistent estimators of the parameters. In this thesis I will carry out a simulation study to examine the performance of current existing methods and I will examine the resampling method for correcting bias of estimators of variance components of a multilevel model with covariates. This study will be based on these three papers: “Weighting for Unequal Selection Probabilities in Multilevel Models” by D. Pfeffermann , C. J. Skinner, D.J. Holmes, …

Exploring Newcomer Settlement And Integration Supports In Brantford, And Brant-Haldimand-Norfolk Counties: Community-Based Participatory Research, Bharati Sethi

Theses and Dissertations (Comprehensive)

Much of the literature on recent immigrants focuses on a needs analysis from a deficit model where primarily formal services and programs related to employment issues are analyzed from a post-positivist or interpretivist framework. Using a strength-based approach this study examined other settlement issues including employment that are vital to the long-term viability of newcomers and the host society such as access to education, training (language and/or vocational), health care, and social network. Using Community Based Participatory Research (CBPR) philosophical framework and methodology, data were generated from various sources—quantitative and qualitative text in the survey questionnaire (service providers and newcomers), …

Implementing Technology In The Classroom: Assessing Teachers’ Needs Through The Use Of A Just-In-Time Support System, Alissa N. Anderson

Theses and Dissertations (Comprehensive)

Given the importance of computer technology in classrooms today, it is crucial to identify the types of supports that will facilitate teachers’ effective implementation of technology. Ten teachers (four kindergarten, four grade one, and two grade one/two) received just-in-time support while introducing a reading software program in their class. An additional 12 teachers (four kindergarten, seven grade one, and one grade two) were exposed to the software, but did not receive just-in-time support. Both quantitative and qualitative analyses of instructional sessions were conducted in order to determine the kinds of support that teachers required throughout the intervention. Results provided an …

Laboratory Studies In Chemically Mediated Phosphorus Removal, Rebecca L. Gilmore

Theses and Dissertations (Comprehensive)

Chemically mediated phosphorus removal, done during wastewater treatment, is an effective means of reducing nutrient loads to sensitive environments. Although this method of treatment is widely used, the mechanism of removal is poorly understood. Moreover, phosphorus regulations for wastewater effluents are moving to concentration ranges of 10-100 μg P/L (total phosphorus). This is much lower than current regulations (∼0.1 ∼0.2 mg P/L as TP) required by municipalities (Takács et al., 2006a; Murthy et al., 2005). The analytical methods for low level phosphate analysis need to be optimized to perform reliably and accurately at these low levels. To accomplish this, absorbance …

Population Density, Circulating Testosterone And Dawn Chorus Behaviour In White-Throated Sparrows (Zonotrichia Albicollis), Simon Richard Hall

Theses and Dissertations (Comprehensive)

An integrative approach to biological research has facilitated the study not only of specific phenomena, but of the connections between these phenomena. A particularly striking example is that of the relationships between testosterone, social behavior, and social context. Increased levels of testosterone increase the frequency of aggressive behaviors and reduce the quality of parental care in many songbird species, and these changes in behavior can affect the surrounding social environment. Different social contexts, population density as a readily studied example, affect the cues that control the release of testosterone into the bloodstream. The distinct tan-stripe and white-stripe phenotypic morphs of …

Effects Of Context On Target Localization, Cheryl M. Lavell

Theses and Dissertations (Comprehensive)

The purpose of this thesis was to investigate how the presence of non-target objects can influence the planning of a movement towards a remembered target location. One specific aim was to examine how the temporal effects of the task could affect movement planning. The final aim of this thesis was to examine whether or not the mere presence of extrinsic cues can suppress the encoding of intrinsic cues.

It was found that when non-target objects are presented simultaneously with the target, interference occurs; however, if the non-target objects are presented at least 250 ms in advance of the targets performance …

First-Passage Time Models With A Stochastic Time Change In Credit Risk, Hui Li

Theses and Dissertations (Comprehensive)

Many authors have used a time-changed Brownian motion as a model of log-stock returns. Using a Levy process as a stochastic time change, one obtains well known asset price models such as the variance gamma (VG) and normal inverse Gaussian (NIG) models. Following on the heels of these asset price models, it is natural to extend structural credit models by using a time-changed geometric Brownian motion and other jump-diffusion processes to model the value of a firm. To avoid the difficulties that arise in computing the associated first passage time distribution and in analogy to the time-changed Markov chain models, …

Piecing Together The Puzzle Of Autism: Aspects Of Its Effects On Children With The Condition And Their Caregivers, Roula Markoulakis

Theses and Dissertations (Comprehensive)

As one of the most prevalent developmental disorders, extensive research exists concerning Autism Spectrum Disorders (ASD). However, gaps are still evident in a number of areas. Information pertaining to any costs and benefits associated with the experience of caring for a child with autism is inadequate. In Study 1, the lived experiences of married female primary caregivers of children with autism were explored, specifically by examining the costs and benefits of caregiving and its influence on the women’s situations. Furthermore, motor control deficits are apparent in many children with high functioning autism (HFA) and Asperger syndrome (AS), but need to …

London As Delaware?, Adam C. Pritchard

Articles

Jurisdictional competition in corporate law has long been a staple of academic-and sometimes, political-debate in the United States. State corporate law, by long-standing tradition in the United States, determines most questions of internal corporate governance-the role of boards of directors, the allocation of authority between directors, managers and shareholders, etc.-while federal law governs questions of disclosure to shareholders-annual reports, proxy statements, and periodic filings. Despite substantial incursions by Congress, most recently in the Sarbanes-Oxley Act of 2002, this dividing line between state and federal law persists, so state law arguably has the most immediate impact on corporate governance outcomes.

Limits Of Interpretivism, Richard A. Primus

Articles

Justice Stephen Markman sits on the Supreme Court of my home state of Michigan. In that capacity, he says, he is involved in a struggle between two kinds of judging. On one side are judges like him. They follow the rules. On the other side are unconstrained judges who decide cases on the basis of what they think the law ought to be. This picture is relatively simple, and Justice Markman apparently approves of its simplicity. But matters may in fact be a good deal more complex.

Procedural Obstacles To Reviewing Ineffective Assistance Of Trial Counsel Claims In State And Federal Postconviction Proceedings., Eve Brensike Primus

Articles

Ineffective assistance of trial counsel is one of the most frequently raised claims in state and federal postconviction petitions. This is hardly surprising given reports of trial attorneys who refuse to investigate their cases before trial, never meet with their clients before the day of trial, and fail to file any motions or object to inadmissible evidence offered at trial. Unfortunately, the current structure of indigent defense funding makes it impossible for many public defenders to provide effective representation to their clients.

Starting Out: Changing Patterns Of First Jobs For Michigan Law School Graduates, Terry K. Adams, David L. Chambers

Articles

In the early 1950s, the typical graduate of Michigan Law began his career working as an associate in a law firm with four other lawyers and earned about $5,000 in his first year. Surprising to us today, in his new job he would have earned slightly less than other classmates whose first jobs were in government. Fifty years later, in the early 2000s, the typical graduate still started out as an associate in a law firm, but the firm she worked for had more than 400 lawyers. She earned about $114,000 in her first year, about three times as much …

The Oecd Harmful Tax Competition Report: A Tenth Anniversary Retrospective, Reuven S. Avi-Yonah

Articles

Eleven years ago the Organisation for Economic Co-operation and Development published its report "Harmful Tax Competition: An Emerging Global Issue." The Report identified for the first time two problem areas facing international income taxation of geographically mobile activities: tax havens and harmful preferential tax regimes. It sought to initiate activities to eliminate both types of problems.

Structure, Composition, And Mechanical Properties Of Australian Orthodontic Wires, Brian M. Pelsue, Spiros Zinelis, T. Gerard Bradley, David W. Berzins, Theodore Eliades, George Eliades

School of Dentistry Faculty Research and Publications

Objective: To investigate the surface morphology, structure, elemental composition, and key mechanical properties of various sizes and tempers of Australian wires.

Materials and Methods: Three types of Australian wire were used: 0.016″ regular, 0.018″ regular+, and 0.018″ special+ (A.J. Wilcock, Whittlesea, Victoria, Australia). Each type of wire was subjected to scanning electron microscopy (SEM) analysis, x-ray energy dispersive spectroscopy (EDS) investigation, Vickers hardness testing, and tensile testing. The modulus of elasticity and ultimate tensile strength were determined. Hardness, modulus, and strength data were analyzed with one-way analysis of variance (ANOVA) and Tukey testing at the .05 level of significance.

Results: …

Comparison Of Porcelain Surface And Flexural Strength Obtained By Microwave And Conventional Oven Glazing, Soni Prasad, Edward A. Monaco, Jr., Hyeongil Kim, Elaine L. Davis, Jane D. Brewer

School of Dentistry Faculty Research and Publications

Statement of problem. Although the superior qualities of microwave technology are common knowledge in the industry, effects of microwave glazing of dental ceramics have not been investigated.

Purpose. The purpose of this study was to investigate the surface roughness and flexural strength achieved by glazing porcelain specimens in a conventional and microwave oven.

Material and methods. Thirty specimens of each type of porcelain (Omega 900 and IPS d.Sign) were fabricated and sintered in a conventional oven. The specimens were further divided into 3 groups (n=10): hand polished (using diamond rotary ceramic polishers), microwave glazed, and conventional oven …

The Federal Courts As A Franchise: Rethinking The Justifications For Federal Question Jurisdiction, Gil Seinfeld

Articles

The components of the Federal Franchise model-procedural homogeneity, cultural conformity, and technical competence-should be familiar. The federal courts' capacity to provide these benefits has not escaped commentators' notice; indeed, there are points of connection between these features of federal court adjudication and the individual fragments of the conventional account.l0 But prior scholarly discussion of these themes has been unsystematic, treating them as (at best) secondary considerations when it comes to the allocation of federal question cases between the state and federal courts. This Article attempts to weave together these previously disconnected strands of thinking about federal court adjudication and to …

Secondary Human Rights Law, Monica Hakimi

Articles

In recent years, the United States has appeared before four different treaty bodies to defend its human rights record. The process is part of the human rights enforcement structure: each of the major universal treaties has an expert body that reviews and comments on compliance reports that states must periodically submit. What's striking about the treaty bodies' dialogues with the United States is not that they criticized it or disagreed with it on the content of certain substantive rules. (That was all expected.) It's the extent to which the two sides talked past each other. Each presumed a different set …

When 'Good' Corporate Governance Makes 'Bad' (Financial) Firms: The Global Crisis And The Limits Of Private Law, Nicholas C. Howson

Articles

In the aftermath of the global financial crisis of 2008–2009, investors, analysts, legislators, and pundits have spotlighted “good” or “improved” corporate governance as a remedy for all that presently ails us. It is one remedy in a long wish list that includes tougher requirements for risk capital, liquidity, and leverage; compensation and bonus reform; reimposition ofthe Glass-Steagall-like separation of bank “utility” and “casino” functions; the downsizing or breakup of institutions deemed “too big to fail;” enhanced consumer protection; securities law liability for secondary violators (like credit rating agencies); direct taxation of proprietary trading; “macroprudential” regulation; and new transparency requirements for …

Communicating Worry: An Intrapersonal Perspective, Linda Vangelis

Iowa Journal of Communication

Existing social science research on worry generally takes a psychological slant, focusing on categories and characteristics of worry, and the reasons people worry. Some of the current literature also provides strategies on how to cope with worry. This essay extends the current research by offering the reader insights into the intrapersonal communication of this emotion. This article is an autoethnographic, layered account of the author's lived experience as a worrier. Through the use of episodic vignettes, the author explores her thoughts and feelings while in the throes of a cycle of worry, offering the readers a glimpse into the everyday, …

The Effects Of Varying Seeding Rates Of Bouteloua Curtipendula And Mowing On Native Plant Establishment In A New Prairie Reconstruction, Ryan Leon Welch

Dissertations and Theses @ UNI

A major problem early in prairie reconstruction is weed competition. Research has shown that mowing in the first year can increase establishment and survival of prairie plants. The use of nurse crops (companion crops) has been suggested as an alternative to mowing for weed suppression. The goal of this study was to examine various seeding rates of B. curtipendula, as a nurse crop in mowed and unmowed plots to determine if it suppressed weeds and aided in the establishment of natives. We hypothesized that increasing the seeding rate of B curtipendula will reduce weed growth and promote an increase in …

A Master’S Recital In Voice, Elizabeth Ann Carr

Dissertations and Theses @ UNI

On Wednesday, March 11, 2009, Elizabeth Ann Carr, soprano, presented a recital in partial fulfillment of the Master of Music Degree in vocal performance. The recital opened with On this Island, a cycle of songs by Benjamin Britten, set to the collection of poetry by W.H. Auden entitled Look, Stranger! This cycle was followed by three melodies by Faure, on the poetry of Verlaine and Samain. The second half of the recital featured Menotti's Canti della lontananza on text written by the composer, and the last set consisted of three complimentary songs of Joseph Marx on text by Lingen, Hartleben, …

Sticks And Stones, The Words That Hurt: Entrenched Stereotypes Eight Years After 9/11, Sahar F. Aziz

Faculty Scholarship

Notwithstanding the passage of eight years, "post-9/11 discrimination" persists, most profoundly in the workplace. While the volume of cases has seemingly decreased, negative stereotypes of Muslims and Arabs have become entrenched into popular culture and consequently more prevalent in the workplace. One need only recall the 2008 presidential elections where allegations that Barack Obama was a Muslim or Arab were in effect racial slurs and ethnic epithets. Months after Barack Obama's inauguration, anti-Muslim sentiment continues in the form of the growing "Birther" movement challenging the validity of President Obama's Hawaiian birth certificate, and ultimately the legitimacy of his presidency, on …

Are You A Boy Or A Girl - Show Me Your Real Id, James Mcgrath

Faculty Scholarship

Although many official documents and forms of identification contain a sex or gender identifier, gender, as a category on these documents, is not very helpful in confirming a person's identity. If the purpose of the inclusion of gender on official documents is to accurately identify an individual, technological advances have given us more accurate methods of ensuring a person's identity. Technologies such as fingerprinting, facial recognition and retinal scans are far superior methods of determining whether a person is who they claim to be. The use of gender or sex on identification cards does little to positively identify individuals, and …

Changing The Rules Of The Game: Offshore Financial Centers, Regulatory Competition & Financial Crises, Andrew P. Morriss

Faculty Scholarship

Politicians from New York District Attorney Robert Morgenthau to British Prime Minister Gordon Brown are blaming offshore financial centers (OFCs) for contributing to the current global financial crisis by failing to adequately regulate their financial industries. These criticisms are mistaken for three reasons. First, OFCs offer different rather than less regulation. Since most OFC financial products are aimed at sophisticated and institutional investors, OFC regulators are less concerned with protections for retail investors than are regulators in jurisdictions like the United States. This enables them to adopt less costly regulations that are still effective at preventing fraud and other financial …

Pollution Swapping: The Effect Of Phosphorus Sequestration On Denitrification In Wetland Sediments, Nathaniel Femi Adegboyega

Dissertations and Theses @ UNI

Surface water quality is currently one of the most important environmental issues facing the state of Iowa since the ecological and recreational health of water bodies are threatened by non-point pollution. Most of Iowa's lakes are polluted because of their high concentration of nutrients, often phosphorus (P), which leads to excessive algal growth (eutrophication). To prevent eutrophication, it is necessary to prevent P from entering surface waters or to sequester (make unavailable to algae) the P that is already in the water body. One method to achieve this is to introduce substances that can tightly fix P (sorption).

Methodological Background Of Decision Rules And Feedback Tools For Outcomes Management In Psychotherapy, Wolfgang Lutz, Niklaus Stulz, Zoran Martinovich, Scott Leon, Stephen M. Saunders

Psychology Faculty Research and Publications

Systems to provide feedback regarding treatment progress have been recognized as a promising method for the early identification of patients at risk for treatment failure in outpatient psychotherapy. The feedback systems presented in this article rely on decision rules to contrast the actual treatment progress of an individual patient and his or her expected treatment response (ETR). Approaches to predict the ETR on the basis of patient intake characteristics and previous treatment progress can be classified into two broad classes: Rationally derived decision rules rely on the judgments of experts, who determine the amount of progress that a patient has …
