Assessment Of Social Anxiety In Early Childhood: Initial Test Construction And *Validation., Daniel B. Chorney Jan 2009

Assessment Of Social Anxiety In Early Childhood: Initial Test Construction And *Validation., Daniel B. Chorney

Graduate Theses, Dissertations, and Problem Reports (ETD)

Social anxiety is experienced across the lifespan, with many individuals reporting symptoms of anxiety and shyness from a very early age in childhood. A number of measures have been designed to assess social anxiety in children, adolescents, and adults, yet little attention has been focused on children below 8 years of age. While some debate exists concerning children's ability to reliably report symptoms of anxiety in early childhood, recent research has indicated that accurate data can be obtained if the measures utilized are developmentally sensitive and not simply downward extensions of measures used to examine social anxiety in adults. Obtaining …

Functional Characterization Of Pag1, The Α7 Subunit Of The 20s Proteasome And Of The Ubiquitin-Specific Protease Subfamilies Ubp12/13 And Ubp3/4 In Arabidopsis Thaliana., Gulsum Soyler-Ogretim

Graduate Theses, Dissertations, and Problem Reports (ETD)

The ubiquitin/26S proteasome system (UPS) is conserved in all eukaryotic species. The 26S proteasome serves as the protease in this pathway and is responsible for the degradation of abnormal and short-lived proteins after their modification with a polyubiquitin tag. It consists of one or two ATP-dependent, 19S regulatory particles and an ATP-independent 20S core protease. PAG1 serves as one of at least 14 different subunits of the 20S core protease. In this study, the role of the 20S core protease in general and PAG1, the α7 subunit of the 26S proteasome, in particular during Arabidopsis growth and development was investigated …

Evaluation Of Weaning Regimen And Seminal Plasma Biology On Reproductive Management In Cattle, John Fredrick Odhiambo Dec 2008

Evaluation Of Weaning Regimen And Seminal Plasma Biology On Reproductive Management In Cattle, John Fredrick Odhiambo

Graduate Theses, Dissertations, and Problem Reports (ETD)

The goal of any reproductive management system in cattle is to ensure that cows breed at the earliest opportune time and maintain their pregnancy to term. However, delayed resumption of postpartum ovarian cyclic activity in primiparous beef cows and pregnancy losses in dairy cows continue to impede progress in obtaining sound reproductive efficiency in these species. Three studies were designed to test the following hypotheses: (1) Does removal of lactational stress in beef cows by early weaning of calves improve cow energy profile and postpartum reproductive performance? (2) Does artificial insemination (AI) with adjunctive seminal plasma (SP) or transforming growth …

Caveolin-1 Recruitment To The Trailing Edge Of Motile Cells Results In Focal Adhesion Disassembly And Nascent Interaction With Actin Stress Fibers, Andrew Beardsley

Graduate Theses, Dissertations, and Problem Reports (ETD)

The protein caveolin-1 has been shown to positively affect angiogenesis and vascular remodeling in vivo via studies using knockout mice. In fact, defects in these two processes are among the major hallmarks of an otherwise benign caveolin-null phenotype. Current dogma on the function of caveolin-1 does not predict or account for these deficits. The overall objective of the following studies was to uncover the role of caveolin-1 in angiogenesis and vascular remodeling through study of the protein in cell-substratum remodeling during cell motility in vitro.;In the first study, caveolin-1 and its parent organelle, caveolae, conspicuously polarize to the rear of …

Communicative Functions Of Young Children's Visual Art, Clover Simms Wright Dec 2008

Communicative Functions Of Young Children's Visual Art, Clover Simms Wright

Graduate Theses, Dissertations, and Problem Reports (ETD)

How can young children use visual art to communicate? This study used Halliday's communicative functions of language (Halliday, 1973), to frame the answer to this question; Halliday's categories of communicative functions are: instrumental, regulatory, interactional, personal, heuristic, imaginative, and representational/informative. Five children, between the ages of three and five, were observed and interviewed as they voluntarily created visual art over a six-week period. In that time period, each of the seven functions of language was demonstrated collectively by the participants. The research was conducted by an educator employed in the early childhood setting. Qualitatively, this study confirmed that young children …

The Use Of Chickens To Remove The Infective Stage Of Haemonchus Contortus From The Field After Sheep Have Grazed, Jessica Harley Nicole Eddy Dec 2008

The Use Of Chickens To Remove The Infective Stage Of Haemonchus Contortus From The Field After Sheep Have Grazed, Jessica Harley Nicole Eddy

Graduate Theses, Dissertations, and Problem Reports (ETD)

There are few USDA organic certified practices for controlling the nematode Haemonchus contortus. This small ruminant parasite has a life cycle that makes it a candidate for control using field rotations. The third-stage of the nematode's life cycle is responsible for infecting or re-infecting a host and the use of chickens to control H. contortus has not been tested. This experiment was conducted to determine if the chicken's foraging behavior reduces the number of infective third-stage larvae on the pasture by comparing a chicken sub-plot, a sub-plot that was mowed, a control sub-plot and a pretreatment. These forage removal methods …

Hemodynamics Of Intracranial Aneurysms: Factors That May Influence Occurrence, Francisco Adolfo Pino Romainville Dec 2008

Hemodynamics Of Intracranial Aneurysms: Factors That May Influence Occurrence, Francisco Adolfo Pino Romainville

Graduate Theses, Dissertations, and Problem Reports (ETD)

The formation and growth of intracranial aneurysms are partly attributed to various hemodynamic factors, such as the wall shear stress and pressure. However, the exact nature of the hemodynamic variables responsible for triggering aneurismal growth is still unknown. The conclusions drawn by various studies in this regard are found to be speculative and sometimes ambiguous. This issue is further investigated in the present work using some new insight gained from passive scalar dispersion in the blood flow for realistic aneurysm geometries. Intracranial aneurysms are best visualized using selective catheter angiogram technique where a contrast agent added to the blood flow …

Association Of Changes In Norepinephrine And Serotonin Transporter Expression With The Long-Term Behavioral Effects Of Antidepressant Drugs, Zaorui Zhao Aug 2008

Association Of Changes In Norepinephrine And Serotonin Transporter Expression With The Long-Term Behavioral Effects Of Antidepressant Drugs, Zaorui Zhao

Graduate Theses, Dissertations, and Problem Reports (ETD)

The relationship between the ability of repeated antidepressant treatment to cause down-regulation of the norepinephrine and serotonin transporters (NET, SERT) and produce antidepressant-like effects on behavior was determined. Treatment of rats with 15 mg/kg/day desipramine reduced NET expression, measured by 3H-nisoxetine binding and SDS-PAGE/immunoblotting, in cerebral cortex and hippocampus and reduced the time of immobility in the forced-swim test. The antidepressant-like effect on forced-swim behavior was evident two days following discontinuation of desipramine treatment when plasma and brain levels of desipramine and its major metabolite desmethyldesipramine were not detectable. Reduced NET expression resulted in decreased norepinephrine (NE) uptake, measured in …

The Growth Of Nonprofit Accounting And It's Impact On Human Services, Roger A. Lohmann Jul 2008

The Growth Of Nonprofit Accounting And It's Impact On Human Services, Roger A. Lohmann

Faculty & Staff Scholarship

Changes in nonprofit accounting standards and practices have spearheaded a quiet revolution in financial management practice in social agencies and the delivery of human services during the past three decades. These changes have gone hand-in-glove with other changes in the political arena to dramatically transform the ways in which human services are organized and delivered. At the core of this transition has been the movement from fund to enterprise accounting, together with such larger political developments as the expansion of grant-based relations with government into the performance management environment of purchase of service contracting.
