Sexual Selection And Plumage In The Polymorphic White-Throated Sparrow, Nathan Rathbun

All-Inclusive List of Electronic Theses and Dissertations

Feather coloration has been known to be connected with sexual selection for many years. It also provides an opportunity to study evolution, focusing on sexual selection and natural selection. Plumage is affected by both of these forces and the equilibrium is where these forces balance. The white-throated sparrow gives us a unique opportunity to observe the effects of the different strengths of these forces within a species. First, I established that there were differences in plumage characteristics between the morphs and sexes. White males had the brightest white and darkest black feathers. White females and tan males were the next …

Extracellular Matrix Proteins: Implications For Angiogenesis, Kent Edward Williams

All-Inclusive List of Electronic Theses and Dissertations

The extracellular matrix (ECM) is an essential requirement for maintaining permanent shape and rigidity in multicellular organisms. The ECM serves two main functions: scaffolding and signaling. Insoluble collagen and soluble proteoglycans, glycosaminoglycans (GAGs), and glycoproteins allow for water retention and flexibility. The signaling role of the ECM is essential for a multitude of events including vascular development and angiogenesis. Via interactions with vascular endothelial cells, proteins of the ECM can induce or repress angiogenesis.

A Comparison Of The Violence Risk Appraisal Guide, Psychopathy Checklist, And Child And Adolescent Taxon Scale: Predictive Utility And Cross Cultural Generalizable, Michael Bruce Lister

All-Inclusive List of Electronic Theses and Dissertations

The Violence Risk Appraisal Guide (VRAG) is a widely utilized measure for estimating the risk of violent reoffending among forensic populations. However, completing the VRAG can be a lengthy process as it requires entering scores from a second test, the Psychopathy Checklist Revised (PCL-R), which must be administered separately and requires hours to complete. In order to reduce scoring time, the authors of the VRAG have developed a brief checklist, the Child and Adolescent Taxon Scale (CATS), which can be used in place of the PCL-R as a more efficient method of assessing psychopathy (Quinsey et al., 2004). Previous research …

Perception Of Control: Accuracy Among Optimists And Pessimists On Noncontingency And Contingengy Tasks, Spencer Baum

All-Inclusive List of Electronic Theses and Dissertations

The learned helplessness theory asserts that depressed individuals unrealistically believe that they have little to no control over aversive outcomes in their lives. Paradoxically, research on judgment of control has demonstrated that depressed individuals are not necessarily pessimistic, but rather more realistic than non-depressed individuals. Most of the research on depressive realism has investigated individual's perceived control in situations in which they have no actual control. Few studies have investigated perception of control in situations where control is possible. Considering that many circumstances in life are controllable, it is important to examine how different personality variables contribute to accurate judgments …

Internal Magnetic Structure Of Magnetite Nanoparticles At Low Temperature, Kathryn L. Krycka, Julie A. Borchers, R.A. Booth, C.R. Hogg, Yumi Ijiri, W.C. Chen, S.M. Watson, M. Laver, T.R. Gentile, S. Harris

Faculty & Staff Scholarship

Small-angle neutron scattering with polarization analysis reveals that Fe3O4 nanoparticles with 90 Å diameters have ferrimagnetic moments significantly reduced from that of bulk Fe3O4 at 10 K, nominal saturation. Combined with previous results for an equivalent applied field at 200 K, a core-disordered shell picture of a spatially reduced ferrimagnetic core emerges, even well below the bulk blocking temperature. Zero-field cooling suggests that this magnetic morphology may be intrinsic to the nanoparticle, rather than field induced, at 10 K.

Pond Ide: Machine Level Program Development Environment And Register Transfer Level Simulator For A Massively Parallel Computer Architecture, Jesse Muszynski

Theses

As computing architectures are being implemented in late and post silicon technologies, fault tolerance and concurrent operation are becoming increasingly important. It is already common knowledge that manufacturers are putting two, four or even more cores on a single silicon die to improve computing performance. The proposed architecture far exceeds this number by grouping thousands or even millions of simple reduced instruction set computing (RISC) processors, each of which is capable of a single operation at a time, and to communicate with its eight nearest neighbors. In this architecture, if a single core or cluster of cores have defects at …

Perceptions Of Faculty Caring: Comparison Of Distance And Traditional Graduate Nursing Students, Lea R. Hall

All-Inclusive List of Electronic Theses and Dissertations

The concept of caring has played a vital role in nursing education. Role modeling has been identified as the primary way to teach caring and has been investigated extensively. As caring has evolved, so has the ways in which we educate nurses. Countless institutions now offer distance education programs in nursing in an effort to address the nurse and nurse educator shortage. It is unclear, however, from the nursing education literature if the modeling of caring can be transferred to students in a distance learning environment. This study investigated the impact of learning environment, program satisfaction, and persistence on graduate …

Numerical Simulation Of Capsule Dissolution In The Usp Apparatus Ii, Jasmine Han

Master's Theses

The capsule is the second most common type of drug dosage form, yet detailed research of capsule dissolution in the USP Apparatus II (a paddle dissolution apparatus that mimics the drug dissolution process in an in vivo environment) is not well reported. In this work, a mathematical model was developed that incorporates both the dissolution of the capsule shell and the slug within the capsule shell. Capsule shell dissolution was modeled with the assumption that the shell undergoes an erosion process only. The capsule slug dissolution model incorporated mass transfer principles, Markov chain theory, and the influence of hydrodynamics on …

Cooperative Symbol-Based Signaling For Networks With Multiple Relays, Yuanyuan Quan

Master's Theses

Wireless channels suffer from severe inherent impairments and hence

reliable and high data rate wireless transmission is particularly challenging to

achieve. Fortunately, using multiple antennae improves performance in wireless

transmission by providing space diversity, spatial multiplexing, and power gains.

However, in wireless ad-hoc networks multiple antennae may not be acceptable

due to limitations in size, cost, and hardware complexity. As a result, cooperative

relaying strategies have attracted considerable attention because of their abilities

to take advantage of multi-antenna by using multiple single-antenna relays.

This study is to explore cooperative signaling for different relay networks,

such as multi-hop relay networks formed …

Paying The Price For Too Big To Fail, Cornelius K. Hurley

Faculty Scholarship

We find ourselves in an economic crisis, the severity of which few persons living today have witnessed. Fear, the natural accompaniment of such crises, arises from our uncertainty about the depth and duration of the crisis. The consensus is that a restoration of confidence is fundamental to a recovery. From the eye of the storm, it is difficult to assess the effectiveness of attempts at quelling its ravages. Yet, we may have little choice but to begin making those assessments as the architecture of the new order is being designed now.

The origins of the current crisis are well recorded. …

Current Patent Laws Cannot Claim The Backing Of Human Rights, Wendy J. Gordon

Faculty Scholarship

In the dispute over the enforcement of pharmaceutical patents, the International Covenant on Economic, Social and Cultural Rights is sometimes cited as giving patent protection the status of a 'human right'. It is true that the ICESCR provides for ‘the right of everyone’ ‘[t]o benefit from the protection of the moral and material interests resulting from any scientific, literary or artistic production of which he is the author’. But that does not mean that patent protection is a human right. Patent fails as a human right for many reasons, one of which is the lack of fit between current patent …

Threshold Interval Indexing Techniques For Complicated Uncertain Data, Andrew Knight

Theses

Uncertain data is an increasingly prevalent topic in database research, given the advance of instruments which inherently generate uncertainty in their data. In particular, the problem of indexing uncertain data for range queries has received considerable attention. To efficiently process range queries, existing approaches mainly focus on reducing the number of disk I/Os. However, due to the inherent complexity of uncertain data, processing a range query may incur high computational cost in addition to the I/O cost. In this paper, I present a novel indexing strategy focusing on one-dimensional uncertain continuous data, called threshold interval indexing. Threshold interval indexing is …

From Medical Images To Individualized Cardiac Mechanics: A Physiome Approach, Chun Wong

Theses

Cardiac mechanics is a branch of science that deals with forces, kinematics, and material properties of the heart, which is valuable for clinical applications and physiological studies. Although anatomical and biomechanical experiments are necessary to provide the fundamental knowledge of cardiac mechanics, the invasive nature of the procedures limits their further applicability. In consequence, noninvasive alternatives are required, and cardiac images provide an excellent source of subject-specific and in vivo information. Noninvasive and individualized cardiac mechanical studies can be achieved through coupling general physiological models derived from invasive experiments with subject-specific information extracted from medical images. Nevertheless, as data extracted …
