An Investigation Of Response To Intervention Implementation In 24 Middle Schools Located Throughout Westchester, Putnam, And Rockland Counties In New York State, Noreen Urso

Education Doctoral

Response to Intervention (RTI) was a major change to the way school districts across the country provided intervention to students at risk of lagging behind in the areas of reading, math, and behavior with a focus on early reading instruction, changing the way all school districts provided academic intervention to students and how they identified students with learning disabilities. The Individuals with Disabilities Education Act (IDEA), 2004 provided legislative requirements that all public school districts across the country provide research based reading instruction prior to referring a student to be considered as having a learning disability. Although the federal government …

The present investigation aimed to study the immunolocalization of lubricin in TMJ discs from patients affected by anterior disc displacement with reduction (ADDwR) ADDwoR. Eighteen TMJ displaced disc affected by ADDwoR were processed immunohistochemically, with a polyclonal anti‐lubricin antibody, used at 1:50 working dilution. The percentage of lubricin immunopositive cells (extent score = ES) and the extent of lubricin staining of the disc extracellular matrix (ECM), were evaluated. Each sample was scored for histopathological changes. Percentage of immunostained surface disc cells …

The Use Of Remote Sensing For Mapping Possible Vectors Of West Nile Virus In Mississippi, Brian Matthew Moore

Master's Theses

There is renewed interest in disease surveillance due to the persistence of numerous vector-borne diseases. Though the life-history processes of disease vectors are known to dictate their distribution patterns, it has been hypothesized that vectors, such as local mosquito abundance, could be predicted from factors such as climate and land use/land cover. Remote sensing has been used as a supplement to traditional methods of mosquito surveillance and to map the spatial distribution of mosquito habitats. This, in turn, affords optimism for improved vector/disease management to identify the best use of remote sensing data and geo-statistical techniques to predict and map …

The Relation Between Externalizing Behaviors Of Children With An Autism Spectrum Disorder And The Externalizing Behaviors, Internalizing Symptoms, And Social Problems Of Their Typically-Developing Siblings, Theodore S. Tomeny

Master's Theses

Existing literature regarding the maladjustment of siblings of children with an autism spectrum disorder (ASD) remains inconclusive. Some studies suggest that difficulties associated with having a child with an ASD in the family result in an adverse experience for both parents and siblings. Dissent within. the literature suggests that certain factors, both environmental and genetic, must be present for maladjustment to occur in typically-developing siblings. Parents of a child with an ASD and a typicallydeveloping sibling (ASD group) and parents of two typically-developing siblings (Control group) provided data via online questionnaires. Both diagnostic category and autism symptoms severity were tested …

Mycorrhizal Colonization Of Native Salt Marsh Plants On Mississippi's Gulf Coast And The Effects Of Commercial Mycorrhizal Inoculants On Nursery-Grown Plants, Kathryn Rondot Mcbride

Master's Theses

Salt marshes are important economically and ecologically to the Gulf Coast and other coasts worldwide. Due to human activities, many coastal salt marshes have been degraded or destroyed. Restoration efforts, through the replacement or addition of naturally occurring salt marsh plants, are taking place worldwide. Most restoration plants are raised in nurseries and are not ready for transfer to restoration sites for eight or nine months. Once the plants are at the restoration site many die due to transplant stress. Arbuscular Mycorrhizal Fungi (AMF) may be able to shorten the time the restoration plants need to stay in the nursery …

An Analytical Study Of Air-Sea Co2 Gas Exchange In The Northwest Mississippi Bight Region, Andrea Kathryn Braatz

Master's Theses

With the continued increase of carbon dioxide (CO2) emissions, researchers are concerned with accumulation of excess CO2 within the atmosphere. The ocean is an important sink for the drawdown of atmospheric CO2 concentrations. Due to high spatial and temporal variability, CO2 fluxes in the coastal ocean are not as well characterized as those for the open ocean. More specifically, data for the northern Gulf of Mexico (GOM) coastal region is lacking. A time series analysis of air-sea CO2 flux rates from May through December 2009 was conducted using data collected by The University of Southern Mississippi’s Central Gulf Ocean Observing …

Seven focus groups were conducted with a total of 33 participants, 21 girls and 12 boys, aged 13-18. Adolescents were grouped by age and gender. A moderator, who was trained in focus group methodology, conducted the session using a focus group discussion guide …

The Relationship Of Testosterone And 5-Ht To Aggressive, Self-Aggressive, And Antisocial Behavior In Men, Anne Winston Mcintyre

Master's Theses

Studies of humans show an inconsistent relationship between aggression and T, as well as between T and antisocial and self-aggressive behavior. Other biological variables, including cortisol and brain serotonin, have been implicated as having an effect on the regulation of antisocial and self-aggressive behavior. Researchers have suggested that inconsistencies in the T-aggression relation may be due to the presence of moderating variables. One theory posits that serotonin moderates the relation between T and aggression. The purpose of this study was to examine the relationship between T (as well as cortisol and 5-HT) and aggression-related constructs. A second purpose was to …

Soil Microbes Regulate Ecosystem Productivity And Maintain Species Diversity, Stefan A. Schnitzer, John Klironomos

Biological Sciences Faculty Research and Publications

One of the major goals in ecology is to determine the mechanisms that drive the asymptotic increase in ecosystem productivity with plant species diversity. Niche complementarity, the current paradigm for the asymptotic diversity-productivity pattern, posits that the addition of species to a community increases productivity because each species specializes on different resources and thus can more thoroughly utilize the available resources. At higher diversity the increase in productivity decreases because resources become limiting, resulting in the classic asymptotic diversity-productivity pattern. An alternative but less tested explanation is that density-dependent disease from species-specific soil microbes drive the diversity-productivity relationship by increasing …

Determining The Roles Of Dendritic Cells And Icam-1 In The Transpresentation Of Il-15 To Cd8 T Cells, Spencer W. Stonier

Dissertations and Theses (Open Access)

The maintenance and generation of memory CD8 T cells is dependent on the cytokine IL-15. IL-15 is delivered by a novel mechanism termed transpresentation: IL-15 is presented by a cell expressing IL-15Ralpha to the CD8 T cell which responds via IL-2Rbeta/gamma_c. The identity of what cells transpresent IL-15 to support the survival and homeostatic proliferation of memory CD8 T cells is unknown. Using a transgenic mouse model that limits IL-15 transpresentation to DCs, I have demonstrated that DCs transpresent IL-15 to CD8 T cells. DCs transpresent IL-15 to CD8 T cells during the contraction of an immune response …

Identifying Predictors Of Social Functioning In College Students : A Meta-Analysis., Jennifer Blair Beard

Electronic Theses and Dissertations

This meta-analysis draws studies from the literature on college student persistence, need theories, and positive psychology in investigating the strongest predictors of social functioning in college students in the United States and Canada. The predictor categories included background characteristics, measures of personality, mental health symptomology, coping style, and academic predictors. The results indicated that an individual's level of extraversion (a personality predictor), level of institutional commitment (an academic predictor), and levels of anxiety and depression (mental health predictors) are the strongest predictors of social functioning in college. The moderator analyses revealed that these effects are even stronger in public institutions …

Generational Differences In Perceived Lip Protrusion Esthetics., David Butler 1979-

Electronic Theses and Dissertations

Background: Facial esthetics plays a major part in diagnosis and treatment planning in orthodontics. One aspect of facial esthetics that orthodontist can drastically change, for better or worse, is that of lip position. What is considered esthetic, however, may vary from person to person based on a multitude of variables. Hypothesis: It is hypothesized that the esthetics of lip protrusion differs with age, with a younger layperson preferring a more protrusive lip position than an older person's ideal lip protrusion. Methods: 208 lay people, ages 12+, with no background in the dental field, were surveyed and asked to rank from …

Dna Polymerase Iota Promotes G2/M Checkpoint Activation And Genetic Stability After Uv-Induced Dna Damage., Lindsey Jay Stallons 1983-

Electronic Theses and Dissertations

Unrepaired DNA damage poses a serious threat to the genetic stability of a replicating cell. One mechanism of tolerating this damage is translesion DNA synthesis (TLS), in which an accessory polymerase synthesizes DNA directly across from a damaged template. TLS is carried out by polymerase ? (Pol ?), 1, K, and REV1 in the Y-family and Pol ? in the B-family. Pol ? has the well-characterized ability to perform accurate bypass of the most common UV-induced DNA lesion; loss of Pol ? results in hypermutability and severely increased risk of skin cancer. The high mutation frequency in Pol ?-deficient cells …

Large-Scale Rnai Screen Of G Protein-Coupled Receptors Involved In Larval Growth, Molting And Metamorphosis In The Red Flour Beetle, Hua Bai, Fang Zhu, Kapil Shah, Subba R. Palli

Entomology Faculty Publications

BACKGROUND: The G protein-coupled receptors (GPCRs) belong to the largest superfamily of integral cell membrane proteins and play crucial roles in physiological processes including behavior, development and reproduction. Because of their broad and diverse roles in cellular signaling, GPCRs are the therapeutic targets for many prescription drugs. However, there is no commercial pesticide targeting insect GPCRs. In this study, we employed functional genomics methods and used the red flour beetle, Tribolium castaneum, as a model system to study the physiological roles of GPCRs during the larval growth, molting and metamorphosis.

RESULTS: A total of 111 non-sensory GPCRs were identified in …

Targeted Multistage Delivery Of Nanoparticles To The Bone Marrow, Aman Mann

Dissertations and Theses (Open Access)

Bone marrow is a target organ site involved in multiple diseases including myeloproliferative disorders and hematologic malignancies and metastases from breast and prostate. Most of these diseases are characterized with poor quality of life, and the treatment options are only palliative due to lack of delivery mechanisms for systemically injected drugs which results in dose limitation to protect the healthy hematopoietic cells. Therefore, there is a critical need to develop effective therapeutic strategies that allow for selective delivery of therapeutic payload to the bone marrow. Nanotechnology-based drug delivery systems provide the opportunity to deliver drugs to the target tissue while …

Significance Of Increased Tissue Transglutaminase In Hormone Refractory Prostate Cancer, Amy L. Han

Dissertations and Theses (Open Access)

The progression of hormone responsive to hormone refractory prostate cancer poses a major clinical challenge in the successful treatment of prostate cancer. The hormone refractory prostate cancer cells exhibit resistance not only to castrate levels of testosterone, but also to other therapeutic modalities and hence become lethal. Currently, there is no effective treatment available for managing this cancer. These observations underscore the urgency to investigate mechanism(s) that contribute to the progression of hormone-responsive to hormone-refractory prostate cancer and to target them for improved clinical outcomes.

Tissue transglutaminase (TG2) is a multifunctional pro-inflammatory protein involved in diverse physiological processes such as …

In-Vivo Ct Dosimetry During Virtual Colonoscopy, Jonathon W. Mueller

Dissertations and Theses (Open Access)

Virtual colonoscopy (VC) is a minimally invasive means for identifying colorectal polyps and colorectal lesions by insufflating a patient’s bowel, applying contrast agent via rectal catheter, and performing multi-detector computed tomography (MDCT) scans. The technique is recommended for colonic health screening by the American Cancer Society but not funded by the Centers for Medicare and Medicaid Services (CMS) partially because of potential risks from radiation exposure. To date, no in‐vivo organ dose measurements have been performed for MDCT scans; thus, the accuracy of any current dose estimates is currently unknown.

In this study, two TLDs were affixed to the inner …

Uptake And Metabolism Of 5’-Amp In The Erythrocyte Play Key Roles In The 5’-Amp Induced Model Of Deep Hypometabolism, Isadora Daniels

Dissertations and Theses (Open Access)

UPTAKE AND METABOLISM OF 5’-AMP IN THE ERYTHROCYTE PLAY KEY ROLES IN THE 5’-AMP INDUCED MODEL OF DEEP HYPOMETABOLISM

Publication No. ________

Isadora Susan Daniels, B.A.

Supervisory Professor: Cheng Chi Lee, Ph.D.

Mechanisms that initiate and control the natural hypometabolic states of mammals are poorly understood. The laboratory developed a model of deep hypometabolism (DH) initiated by uptake of 5’-adenosine monophosphate (5’-AMP) into erythrocytes. Mice enter DH when given a high dose of 5’-AMP and the body cools readily. Influx of 5’-AMP appears to inhibit thermoregulatory control. In a 15°C environment, mice injected with 5’-AMP (0.5 mg/gw) enter a Phase …

Mechanism Of Transcriptional Suppression Of A Phytochrome A Epiallele In Arabidopsis Thaliana, Gulab D. Rangani

Graduate Theses and Dissertations

Cytosine methylation in DNA is an integral part of epigenetically controlled regulatory networks in eukaryotes. Both plants and vertebrates display DNA methylation in the gene coding region; however, its role in gene expression is not well understood. Gene promoter, on the other hand, remains largely unmethylated. Acquisition of methylation in promoter results in transcriptional suppression of the gene. The goal of this research is to study the effect of coding region methylation in gene expression using a unique gene model, phyA'. phyA' is a transcriptionally suppressed epiallele of the Arabidopsis thaliana Phytochrome A gene, which contains methylation in CG sites …
