The Effects Of Instructor Self-Disclosure On Students’ Cognitive Learning: A Live Lecture Experiment, Stephen Michael Kromka

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this dissertation was to examine the causal influences of relevant (and irrelevant) instructor self-disclosure on student affect and cognitive learning. Relevant self-disclosure involves the instructor directly relating personal disclosures to important lesson content, whereas irrelevant self-disclosure involves the instructor’s personal disclosures straying from the lesson topic. Given previous correlational self-disclosure research, the researcher predicted that relevant (compared to irrelevant) instructor self-disclosure would lead to increased reports of affect toward the instructor. The researcher also predicted that instructor self-disclosure relevance (compared to irrelevance) would enhance lesson coherence, and in turn, foster students’ cognitive learning. The researcher conducted a …

Cycle Double Covers And Integer Flows, Zhang Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

My research focuses on two famous problems in graph theory, namely the cycle double cover conjecture and the integer flows conjectures. This kind of problem is undoubtedly one of the major catalysts in the tremendous development of graph theory. It was observed by Tutte that the Four color problem can be formulated in terms of integer flows, as well as cycle covers. Since then, the topics of integer flows and cycle covers have always been in the main line of graph theory research. This dissertation provides several partial results on these two classes of problems.

This photoconversion improvement may be manifested as increased photoconversion efficiencies for light harvesting devices for power generation such as photovoltaics and photoelectrochemical (PEC) cells or improved photoconversion modulation to increase the sensitivity of semiconductor photoconversion-based sensors. In addition, alternative semiconductor materials to semiconductors that …

Role Centrality And Shared Activities With Grandchildren: Effects On Grandparent Wellbeing, Madeline Marie Marello

Graduate Theses, Dissertations, and Problem Reports (ETD)

Research shows that physical and mental health are closely linked (Ohrnberger, Fichera, & Sutton, 2017). Further, social role theory states that holding and enacting valued roles, such as grandparenting, can buffer the negative effects of health on depression (Reitzes & Mutran, 2004). Using data from 247 grandparents (Mean age = 66.5; range 42 to 90 years; 46.2% grandfathers), we examined whether grandparent role centrality and engagement with grandchildren altered the effects of physical health on depression. We then explored model differences between 164 custodial and 83 traditional grandparents. We found that for all grandparents the model was of sufficient fit: …

Background

The largest increase in preventable overdose deaths from 1999-2017 occurred among adults 50 and older, yet substance misuse among older adults is often not screened for or recognized in primary care settings. This oversight has been attributed to many factors, including age-related biases, unrecognized psychosocial and physiological differences, stigmatization, and a rapidly growing geriatric population.

Objectives

A quality improvement program using evidence-based educational training was implemented in a primary care setting with the intention to expand care knowledge and ultimately improve screening practices of older adults, especially those suffering from substance misuse.

Design

This quality improvement (QI) project used …

Spatio-Temporal Analysis Of Crime Incidents For Forensic Investigation, Jamie Spencer Spaulding

Graduate Theses, Dissertations, and Problem Reports (ETD)

Crime analysis and mapping has been routinely employed to gather intelligence which informs security efforts and forensic investigations. Traditionally, geographic information systems in the form of third-party mapping applications are used for analysis of crime data but are often expensive and lack flexibility, transparency, or efficiency in uncovering associations and relationships in crime. Each crime incident and article of evidence within that incident has an associated spatial and temporal component which may yield significant and relevant information to the case. Wide variations exist in the techniques that departments use and commonly spatial and temporal components of crime are evaluated independently, …

Estimating The Age Of A Bloodstain Using Mitochondrial Rrna, Jordan R. Flesher

Graduate Theses, Dissertations, and Problem Reports (ETD)

DNA evidence is considered the gold standard of evidence in forensic investigations. DNA is one of the most highly discriminatory pieces of evidence found at crime scenes and can link individuals to scenes. It is not relied on to perform temporal estimates to help establish a timeline for when a crime took place. Previous studies have shown that measurement of the degradation of RNA is a potential tool to establish a temporal estimate of when a blood sample was left at a crime scene. This experiment attempts to improve on previous RNA degradation studies by evaluating the validity of mitochondrial …

Fully Compressible Hydrodynamic Simulation Of Non-Equidiffusive Premixed Flames Propagation In Channels, Olatunde A. Abidakun

Graduate Theses, Dissertations, and Problem Reports (ETD)

Premixed combustion remains of fundamental interest in energy generation and propulsion systems as well as in implementation of safety measures for residential and industrial accidental fire explosions. While the fast pace and complex nature of the combustion process has previously necessitated the analytical and computational studies to employ the simplifying assumption of equidiffusivity, when the Lewis number defined as the thermal-to-mass diffusivities ratio is unity , the ongoing advancements in technology and the requirements for efficiently operating combustors over a wide range of conditions make the combustion process more non-equdiffusive ( ) than ever. The impact of non-equidiffusivity on the …
