Quality Data Is Key To Improving Education, Data Quality Campaign

Journal of Applied Research on Children: Informing Policy for Children at Risk

The Data Quality Campaign (DQC) has been focused since 2005 on advocating for states to build robust state longitudinal data systems (SLDS). While states have made great progress in their data infrastructure, and should continue to emphasize this work, t data systems alone will not improve outcomes. It is time for both DQC and states to focus on building capacity to use the information that these systems are producing at every level – from classrooms to state houses. To impact system performance and student achievement, the ingrained culture must be replaced with one that focuses on data use for continuous …

Commentary On "Alternative Strategies For Identifying High-Performing Charter Schools In Texas", Robin J. Lake

Journal of Applied Research on Children: Informing Policy for Children at Risk

In the last few years policy makers and practitioners nationally have shown much interest in identifying, recognizing, and replicating successful charter schools, many of which are showing that they can educate low-income and otherwise at-risk students remarkably well. However past efforts to identify high performing schools have been problematic. Using these systematic, rigorous value-added methods, the authors identify 44 Open Enrollment charter schools that merit a “high-performer” rating. Nearly all of those campuses identified serve a disadvantaged student population. The article also finds that most of those high performers are highly cost-effective, earning high ratings on the cost-efficiency measures. The …

The Relationship Of Provincial Economic Level And Child Injury Mortality In Thailand: A Cross-Sectional Analysis In A Middle Income Country, Adisak Plitponkarnpim, Ragnar Andersson, Kristen A. Conner, Huiyun Xiang, Gary Smith

Journal of Applied Research on Children: Informing Policy for Children at Risk

The objective of this cross-sectional study was to examine the relationship of provincial economic development indices with incidences of child injury mortality in Thailand from 1999 - 2001. All injury deaths among children age 1-14 years were included. The independent variables included gross provincial product per capita (GPP/c), poverty and inequality indices, material and social deprivation indices, population in rural/ urban areas, and migration. Due to multicollinearity of such variables, the 76 provinces were categorized by GPP/c quartile, and means of overall injury, drowning, and transport-related mortality rates were compared among quartile groups. Spearman’s rho correlation between GPP/c and injury …

Computerizing Social-Emotional Assessment For School Readiness: First Steps Toward An Assessment Battery For Early Childhood Settings, Susanne A. Denham, Hideko H. Bassett, Katherine Zinsser

Journal of Applied Research on Children: Informing Policy for Children at Risk

The transition into formal schooling is a crucial foundation that can set children on a cycle of success or failure in both academic and social domains. A child’s abilities to express healthy emotions, understand emotions of self and others, regulate emotion, attention, and behavior, make good decisions regarding social problems, and engage in a range of prosocial behaviors, all work together to promote a successful school experience.

However, many children have deficits in these skills by school entry, and educators lack the requisite tools to identify, track and assess skills these children need to learn. Thus, because social-emotional learning (SEL) …

Regulation Of Foxc2 Expression And Function During Epithelial-Mesenchymal Transition By Gsk-3Β, Maryam Shariati

Dissertations and Theses (Open Access)

Metastasis is the ultimate cause for the majority of cancer-related deaths. The forkhead box transcription factor FOXC2 is known to be involved in regulating metastasis as well as a variety of developmental processes, including the formation of lymphatic and cardiovascular systems. Previous studies have shown that FOXC2 protein is localized either in the nucleus and/or in the cytoplasm of human breast tumor cells. This pattern of localization is similar to that of another forkhead family member, FOXO3a. Additionally, localization of FOXO3a is known to be differentially regulated by upstream kinase AKT. Therefore, I investigated whether FOXC2 localization could also be …

Genetic Predictors Of Clinical Outcomes In Non-Small Cell Lung Cancer Patients, Xia Pu

Dissertations and Theses (Open Access)

Lung cancer is the leading cause of cancer-related mortality in the US. Emerging evidence has shown that host genetic factors can interact with environmental exposures to influence patient susceptibility to the diseases as well as clinical outcomes, such as survival and recurrence. We aimed to identify genetic prognostic markers for non-small cell lung cancer (NSCLC), a major (85%) subtype of lung cancer, and also in other subgroups. With the fast evolution of genotyping technology, genetic association studies have went through candidate gene approach, to pathway-based approach, to the genome wide association study (GWAS). Even in the era of GWAS, pathway-based …

Understanding The Influence Of Photon Energy On 6mv Non Reference Dosimetry And Ct Dosimetry Using Tld And Osld, Sarah B. Scarboro

Dissertations and Theses (Open Access)

Measurement of the absorbed dose from ionizing radiation in medical applications is an essential component to providing safe and reproducible patient care. There are a wide variety of tools available for measuring radiation dose; this work focuses on the characterization of two common, solid-state dosimeters in medical applications: thermoluminescent dosimeters (TLD) and optically stimulated luminescent dosimeters (OSLD).

There were two main objectives to this work. The first objective was to evaluate the energy dependence of TLD and OSLD for non-reference measurement conditions in a radiotherapy environment. The second objective was to fully characterize the OSLD nanoDot in a CT environment, …

The Regulation Of Mtorc2 Kinase Activity And Complex Integrity, Chien-Hung Chen

Dissertations and Theses (Open Access)

Growth factor signaling promotes anabolic processes via activation of the

PI3K-Akt kinase cascade. Deregulation of the growth factor-dependent PI3K-Akt

pathway was implicated in tumorigenesis. Akt is an essential serine/threonine

protein kinase that controls multiple physiological functions such as cell growth,

proliferation, and survival to maintain cellular homeostasis. Recently, the

mammalian Target of Rapamycin Complex 2 (mTORC2) was identified as the

main Akt Ser-473 kinase, and Ser-473 phosphorylation is required for Akt

hyperactivation. However, the detailed mechanism of mTORC2 regulation in

response to growth factor stimulation or cellular stresses is not well understood.

In the first project, we studied the regulation …

Role Of Stat3 In Keratinocyte Stem Cells During Skin Tumorigenesis, Dharanija Rao

Dissertations and Theses (Open Access)

STATs play crucial roles in a wide variety of biological functions, including development, proliferation, differentiation, migration and in cancer development. In the present study, we examined the impact of Stat3 deletion or activation on behavior of keratinocytes, including keratinocyte stem cells (KSCs). Deletion of Stat3 specifically in the bulge region of the hair follicle using K15.CrePR1 X Stat3^fl/fl mice led to decreased tumor development by altering survival of bulge region KSCs. To further understand the role of KSCs in skin tumorigenesis, K5.Stat3C transgenic (Tg) mice which express a constitutively active/dimerized form of Stat3 called Stat3C via the bovine keratin …

Effects Of The Acta2 R258c Mutation On Vascular Smooth Muscle Cell Phenotype And Properties, Katerina L. Byanova

Dissertations and Theses (Open Access)

Thoracic Aortic Aneurysms and Dissections (TAAD) are the fifteenth leading cause of death in the United States. About 15% of TAAD patients have family history of the disease. The most commonly mutated gene in these families is ACTA2, encoding smooth muscle-specific α-actin. ACTA2 missense mutations predispose individuals both to TAAD and to vascular occlusive disease of small, muscular arteries.

Mice carrying an Acta2 R258C mutant transgene with a wildtype Acta2 promoter were generated and bred with Acta2^-/- mice to decrease the wildtype: mutant Acta2 ratio. Acta2^{+/+ R258C TG}mice have decreased aortic contractility without aortic disease. Acta2 …

Deciphering The C-Type Lectin Receptor Signaling Pathway In Macrophages In Response To Candida Albicans, Sara Gorjestani

Dissertations and Theses (Open Access)

Candida albicans causes opportunistic fungal infections in humans and is a significant cause of mortality and morbidity in immune-compromised individuals. Dectin-2, a C-type lectin receptor, is required for recognition of C. albicans by innate immune cells and is required for initiation of the anti-fungal immune response. We set out to identify components of the intracellular signaling cascade downstream of Dectin-2 activation in macrophages and to understand their importance in mediating the immune response to C. albicans in vivo. Using macrophages derived from Phospholipase-C-gamma 1 and 2 (PLCγ1and PLCγ2) knockout mice, we demonstrate that PLCγ2, but not PLCγ1, is required …

14-3-3 Zeta Overexpression Serves As A Novel Molecular Switch Turning Tgf-Beta From Tumor Suppressor To Tumor Promoter, Jia Xu

Dissertations and Theses (Open Access)

TGF-β plays an important role in differentiation and tissue morphogenesis as well as cancer progression. However, the role of TGF-β in cancer is complicate. TGF-β has primarily been recognized as tumor suppressor, because it can directly inhibit cell proliferation of normal and premalignant epithelial cell. However, in the last stage of tumor progression, TGF-β functions as tumor promoter to enhance tumor cells metastatic dissemination and expands metastatic colonies. Currently, the mechanism of how TGF-β switches its role from tumor suppressor to promoter still remains elusive. Here we identify that overexpression of 14-3-3ζ inhibits TGF-β’s cell cytostatic program through destabilizing p53 …

Chronic Stress Promotes Tumor Growth Through Increased Bdnf Production And Neo-Innervation, Julie K. Allen

Dissertations and Theses (Open Access)

Background: Activation of the sympathetic nervous system (SNS) in response to chronic biobehavioral stress results in high levels of catecholamines and persistent activation of adrenergic signaling, which promotes tumor growth and progression. However it is unknown how catecholamine levels within the tumor exceed systemic levels in circulation. I hypothesized that neo-innervation of tumors is required for stress-mediated effects on tumor growth.

Results: First, I examined whether sympathetic nerves are present in human ovarian cancer samples as well as orthotopic ovarian cancer models. Immunohistochemical (IHC) staining for neurofilament revealed that catecholaminergic neurons are present within tumor tissue. In order to determine …

Fzd6, Matn2 And Slc25a32, Possible Candidate Genes In Nonsyndromic Cleft Lip And Palate, Nevena Cvjetkovic

Dissertations and Theses (Open Access)

Nonsyndromic cleft lip with or without cleft palate (NSCLP) is a common birth defect with a multifactorial etiology. Despite decades of research, the genetic underpinnings of NSCLP still remain largely unexplained. A genome wide association study (GWAS) of a large NSCLP African American family with seven affected individuals across three generations found evidence for linkage at 8q21.3-24.12 (LOD = 2.98). This region contained three biologically relevant candidate genes: Frizzled-6 (FZD6) (LOD = 2.8), Matrilin-2 (MATN2) (LOD = 2.3), and Solute Carrier Family 25, Member 32 (SLC26A32) (LOD = 1.6). Sequencing of the coding regions and the 5’ and 3’ …

Novel Use Of Dual Anti-Inflammatory Therapy To Overcome Drug Resistance And Improve Functional Recovery Following Spinal Cord Injury, Jennifer Dulin

Dissertations and Theses (Open Access)

Over 1.2 million Americans are currently living with a traumatic spinal cord injury (SCI). Despite the need for effective therapies, there are currently no proven effective treatments that can improve recovery of function in SCI patients. Many therapeutic compounds have shown promise in preclinical models of SCI, but all of these have fallen short in clinical trials.

P-glycoprotein (Pgp) is an active transporter expressed on capillary endothelial cell membranes at the blood-spinal cord barrier (BSCB). Pgp limits passive diffusion of blood-borne drugs into the CNS, by actively extruding drugs from the endothelial cell membrane. Pgp can become pathologically up-regulated, thus …

The Histone Deacetylase Inhibitor, Ms-275, Sensitizes Metastatic Osteosarcoma To Fasl-Induced Cell Death: A Role For C-Flip, Krithi R. Bindal

Dissertations and Theses (Open Access)

The purpose of this study was to determine the effects of the histone deacetylase inhibitor, MS-275, on the Fas signaling pathway and susceptibility of osteosarcoma (OS) to Fas ligand (FasL)-induced cell death. OS metastasizes almost exclusively to the lungs. We have shown that Fas expression in OS cells is inversely correlated with their metastatic potential. Fas⁺ cells are rapidly eliminated when they enter the lungs via interaction with FasL, which is constitutively expressed in the lungs. Fas^- OS cells escape this FasL-induced apoptosis and survive in the lung microenvironment. Moreover, upregulation of Fas in established OS lung metastases …
