Label Retention Identifies A Multipotent Mesenchymal Stem Cell-Like Population In The Postnatal Thymus, Masako Osada, Varan J. Singh, Kenmin Wu, Derek B. Sant’Angelo, Mark Pezzano

Publications and Research

Thymic microenvironments are essential for the proper development and selection of T cells critical for a functional and self-tolerant adaptive immune response. While significant turnover occurs, it is unclear whether populations of adult stem cells contribute to the maintenance of postnatal thymic epithelial microenvironments. Here, the slow cycling characteristic of stem cells and their property of label-retention were used to identify a K5-expressing thymic stromal cell population capable of generating clonal cell lines that retain the capacity to differentiate into a number of mesenchymal lineages including adipocytes, chondrocytes and osteoblasts suggesting a mesenchymal stem cell-like phenotype. Using cell surface analysis …

Structure And Dynamics Of Self-Assembling Colloidal Monolayers In Oscillating Magnetic Fields, Alison E. Patteson (Koser), Nathan C. Keim, Paulo E. Arratia

Physics - All Scholarship

Many fascinating phenomena such as large-scale collective flows, enhanced fluid mixing, and pattern formation have been observed in so-called active fluids, which are composed of particles that can absorb energy and dissipate it into the fluid medium. For active particles immersed in liquids, fluid-mediated viscous stresses can play an important role on the emergence of collective behavior. Here, we experimentally investigate their role in the dynamics of self-assembling magnetically driven colloidal particles which can rapidly form organized hexagonal structures. We find that viscous stresses reduce hexagonal ordering, generate smaller clusters, and significantly decrease the rate of cluster formation, all while …

Carbon Fluxes In Karst Aquifers: Sources, Sinks, And The Effect Of Storm Flow, William B. White

KIP Articles

An effective carbon loading can be calculated from measured alkalinity and pH of karst waters. The carbon loading is independent of the degree of saturation of the water and does not depend on the water being in equilibrium with the carbonate wall rock. A substantial data base of spring water analyses accumulated by students over the past 40 years has been used to probe the CO2 generation, transport, and storage in a variety of drainage basins that feed karst springs. Carbon loading in the water exiting karst drainage basins depends on the rate of CO2 generation in the soils of …

Cultural Competence Integration In The Nursing Curriculum, Boniface C. Stegman

Dissertations

With an increasingly diverse population, it is important to ensure that graduates of nursing programs are able to deliver culturally competent care (Krainovich-Miller et al., 2008; Allen, 2010). This study was undertaken to address this call to include cultural competence integration into nursing curriculum. The purpose of this study was to discover evidence of cultural competence integration in the nursing curriculum as perceived by faculty and students in a baccalaureate nursing program. This study addressed the following research questions: a) Does the undergraduate nursing curriculum integrate cultural competence?, b) Do the undergraduate nursing faculty perceive cultural competence content in the …

Lgbt Homeless Youth In Boston, Massachusetts: Experiences Regarding Resources And Potential Barriers, Brittney Connery

Honors Program Theses and Projects

LGBT youth are at an escalated risk of leaving home, mental health concerns, victimization, substance abuse, and risky sexual behavior. However, research shows a lack of LGBT-specific resources. This raises concern as LGBT youth comprise 20 to 40 percent of homeless youth – disproportionate to the general youth population which is only 10 percent LGBT. The purpose of this research was to gain a deeper understanding of the experiences of LGBT homeless youth in Boston, Massachusetts regarding their use of resources and any potential barriers they may face. Furthermore, this study examined whether or not current resources are safe, welcoming …

Pleading Innocents: Laboratory Evidence Of Plea Bargaining's Innocence Problem, Vanessa A. Edkins, Lucian E. Dervan

Psychology Faculty Publications

We investigated plea bargaining by making students actually guilty or innocent of a cheating offense and varying the sentence that they would face if found ‘guilty’ by a review board. As hypothesized, guilty students were more likely than innocent students to accept a plea deal (i.e., admit guilt and lose credit; akin to accepting a sentence of probation) (Chi-square=8.63, p<.01) but we did not find an effect of sentence severity. Innocent students, though not as likely to plead as guilty students, showed an overall preference (56% across conditions) for accepting a plea deal. Implications and future directions are discussed.

Understory Vegetation Response To Mechanical Mastication Of Piñon And Juniper Woodlands, Jordan Ann Bybee

Theses and Dissertations

Piñon and juniper encroachment and infilling can alter ecosystem processes and decrease resilience and resistance in sagebrush grasslands. Land managers employ a variety of techniques to eliminate these trees and mitigate their negative effects. Mechanical mastication or shredding is an increasingly popular method of removing these trees in Utah. It is a versatile treatment that can reduce canopy fuels, increase infiltration, and reduced sediment loss. We compared vegetation cover for annual and perennial vegetation functional groups on shredded and adjacent unshredded areas across a range of sites. Our approach was to categorize sites by ecological site type (encroachment or tree) …

Evidence And Implications Of Weight Clustering Among Adolescents, Jennifer C. Acker

Master's Theses

Both obesity and eating disorders (ED) are increasingly conceptualized from an ecological model of health, which emphasizes the importance of individual and contextual variables. The peer context is particularly important for understanding adolescents’ weight related attitudes and behaviors; however, specific peer processes that impact obesity and EDs are unclear. Because social comparison is common during adolescence, how teens view their body in comparison to the body size of their close friends may be influential. The purpose of this study is to examine how adolescents’ perceptions of their friends’ body sizes relate to their weight-related cognitions, behaviors, and mental health symptoms, …

A "Time-Conscious" Christmas Carol, Jack Lundquist

Theses and Dissertations

Shortly after Charles Dickens's A Christmas Carol was released in 1843, a tradition of adaptation began which has continued seemingly unabated to the present day. Consequently, the tale has become so widely known that one is arguably as likely to have first encountered the iconic miser Scrooge through any number of audio-visual adaptations as through the original work itself. Significant critical attention has been paid to the nature of Scrooge's drastic change from miser to philanthropist. Many would argue that the change, happening both literally and figuratively overnight, is not representative of a genuine psychological transformation. On Christmas day, 2010, …

Intercalibration Of Quikscat And Oscat Land Backscatter, John Colin Barrus

Theses and Dissertations

The Ku-band SeaWinds-on-QuikSCAT scatterometer (QuikSCAT) operated continuously from 1999 to 2009. Though its primary mission was to estimate global ocean winds, QuikSCAT has proven useful in a variety of geophysical studies using land backscatter measurements. The end of the primary QuikSCAT mission in 2009 has prompted interest for continuing the QuikSCAT land dataset with other scatterometers. The Oceansat-2 scatterometer (OSCAT), launched in 2009, is a viable candidate for continuing the QuikSCAT time series because of the similarities of both sensors in function and design. An important difference in the sensors is that they operate at slightly different incidence angles. Continuing …

An Exploration Of Threatened Harm As A Type Of Maltreatment And Its Relation To Recurrence Of Maltreatment, Roxann Mcneish

USF Tampa Graduate Theses and Dissertations

There were no studies found in the literature that primarily focused on threatened harm as type of maltreatment. This study utilized Florida's child welfare administrative data to explore threatened harm as a type of maltreatment, particularly as a predictor of recurrence of maltreatment within six and 12 months for children who had a verified report of maltreatment in FY2005-2006. Threatened harm was examined in three ways; when it was reported as the only maltreatment, the initial maltreatment, and in situations where there was a prior report. The most prevalent acts of threatened harm were examined separately. It was examined as …

Application Of Support Vector Machine In Predicting The Market's Monthly Trend Direction, Ali Alali

Dissertations and Theses

In this work, we investigate different techniques to predict the monthly trend direction of the S&P 500 market index. The techniques use a machine learning classifier with technical and macroeconomic indicators as input features. The Support Vector Machine (SVM) classifier was explored in-depth in order to optimize the performance using four different kernels; Linear, Radial Basis Function (RBF), Polynomial, and Quadratic. A result found was the performance of the classifier can be optimized by reducing the number of macroeconomic features needed by 30% using Sequential Feature Selection. Further performance enhancement was achieved by optimizing the RBF kernel and SVM parameters …

How Does Student Understanding Of A Concept Change Throughout A Unit Of Instruction? Support Toward The Theory Of Learning Progressions, Brian Jay Dyer
