Herpes Virus Infections, Inflammatory Markers And Risk Of Developing T2dm And Cvd: An Analysis Of Nhanes With Adults, Aged 20-49, 1999-2010, Margarita Irizarry-De La Cruz

Walden Dissertations and Doctoral Studies

Herpes simplex viruses (HSVs), are among the most virulent and widespread pathogens; they affect 60-90% of the population worldwide. Substantial evidence indicates a possible association between pathogens and chronic disease. HSVs, among other viruses, have been associated with increased risk for inflammatory diseases. However, prior findings have been inconsistent on the role of infection in triggering autoimmune response and chronic disease. This study builds on the premise that pathogens can induce an inflammatory response and increase the risk for disease development. A representative U.S. sample from NHANES, a national population-based cross-sectional survey, was used to examine the relationship between HSVs …

Elementary School Teacher Perceptions Of Using Formative Strategies To Improve Instruction, Deborah Peterson Bennett

Walden Dissertations and Doctoral Studies

Standardized test data from a southern suburban elementary school showed lagging student scores behind those of students from similar settings. These scores suggested a disconnection between teachers' understanding of and practice in formative assessment. Bloom's revised taxonomy, backward design planning theory, and differentiated learning theory guided this study, which focused on how elementary teachers use formative strategies in the classroom to inform instruction. Data collected through face-to-face interviews from 10 teachers were transcribed and organized in codes and themes. Member checks were then used to ensure credibility of interpretations. The key results showed that these 10 teachers used many formative …

Examining Behavioral Reactivity And Cognitive Differences Within The Chc Theory Of Intelligence Among Children., Steven Matthew Jozwiak

Walden Dissertations and Doctoral Studies

Linking cognition and behavior has long been an area of interest to the field of psychology in its endeavors to understand what innate factors influence human behavior. To date, the majority of research linking emotional reactivity to cognition has focused on single areas of intellectual functioning on specific diagnostic profiles or learning disorders rather than a comprehensive comparison to cognitive profile typology. Nearly all the research conducted to date continues to define cognition and emotion as disparate entities, rather than exploring a more integrated view of emotion and cognition. The purpose of this quantitative study was to examine cognitive profile …

Factors Contributing To The Limited Use Of Information Technology In State Courtrooms, Concetta Manker

Exploring The Impact Of Wyoming's Pathways To Professional Development Program On Childcare Providers And Quality Early Childcare, Colleen Kay Bartlett

Walden Dissertations and Doctoral Studies

Childcare programs that provide high quality care can strengthen children's early development. One component of a quality program is having providers who are knowledgeable in child development; however, despite the understanding of these known predictors of child development, Wyoming does not require childcare providers to complete any training before beginning to work with children. Guided by the constructivist theories of Piaget, Vygotsky, Dewey, and Bruner, this objectives-based program evaluation investigated the Pathways to Professional Development program to determine participants' perceptions of the strengths and weaknesses of the program. A researcher-produced survey was created based on the objectives of the program …

Inflammatory Markers Associated With Disease Progression Of Cardiorenal Syndrome, Srikanta Banerjee

Walden Dissertations and Doctoral Studies

An increase in cellular inflammatory biomarkers directly increases the risk of cardiovascular disease (CVD). Using the social ecological and biomedical theories, the study examined quantitatively how specific inflammatory biomarkers are associated with cardiorenal syndrome (CRS), a potential complication of hypertension and diabetes, and how sociodemographic factors modify this association in the U.S. adult population. A retrospective secondary data analysis of the data collected from National Health and Nutrition Examination Survey (NHANES) 1999-2010 was utilized to evaluate these hypotheses. High sensitivity C-reactive protein, homocysteine (hcy), and fibrinogen had a modifying effect on Type 4 (chronic reno-cardiac etiology), Type 2 CRS (chronic …

The Relationship Of Managers' Power Motivations To Personality Pathology, Jewel Darlene Adams

Walden Dissertations and Doctoral Studies

Research has shown that managerial leaders have a higher motivational need for power than those in other positions. A leader's personality traits have been shown to affect organizational performance. Leaders who score high in dark traits (undesirable personality attributes shown to predict career derailment across organizations, levels, and positions) could also be more likely to use company resources for personal gain. There is a paucity of research examining the correlation between managerial dark traits and the need for power. The purpose of this study was to examine the relationship between managers' dark trait scores as measured by the Hogan Development …

The Relationship Among Esol Services, Vocabulary, And Reading Comprehension In Primary Grades, Cassandra Marie Arcila-Knortz

Albumin Levels In Hispanic Dialysis Patients With And Without Type Ii Diabetes, Hector Hernandez

Walden Dissertations and Doctoral Studies

Albumin provides the vital scaffolding for growth and tissue repair and supports oncotic blood pressure and hemodynamics. In hemodialysis patients, albumin aids with fluid removal by drawing excess fluid from edematous tissues back into the blood where it can then be removed by a dialyzer. The hyperglycemia seen in dialysis patients with Type II diabetes progressively damages kidney glomeruli, which permits albumin seepage into the urine, thus lowering serum albumin. The conceptual framework underpinning this research is the van't Hoff theory of osmotic pressure. Under this framework, the solute-solvent relationship largely contributes to the osmotic movement of fluid. The purpose …

Influences Of Csi Effect, Daubert Ruling, And Nas Report On Forensic Science Practices, Timothy Patrick Scanlan

Walden Dissertations and Doctoral Studies

The media exaggerates the capabilities of crime laboratories while it publicizes the wrongdoings of individual forensic scientists. Such portrayals skew the perspectives of jurors and hinder expert witness testimony. Complicating the problem are separate, but related, phenomena that influence how forensic laboratories conduct casework. These phenomena are Cole and Dioso-Villa's conceptualization of the unrealistic expectations of forensic science created by fictional television, known as the CSI Effect; the Daubert ruling on the admissibility of expert testimony; and some federal policy changes as a result of a National Academy of Sciences (NAS) report that impacted requirements for the daily operation of …
