Student Perception Of Their Instructors Do College Students Rate Female Professors More Harshly?, Courtney Christovich

HIM 1990-2015

Student evaluations are often used by administrators to make important career decisions for professors such as offers of tenure, increase in salary or other monetary reward (see Frick, Chadha, Watson, & Zlatkovska, 2009). Research has consistently shown that helpfulness in its various operational definitions is one of the most important traits to students when evaluating a professor (For example Silva et al., 2008). Previous findings have demonstrated that inequalities exist among subjective student evaluation ratings of men and women, (see Bennet, 1982). The present study extended this research by manipulating the instruction styles (strict vs. permissive), as well as the …

Juvenile Ornamentation: Its Evolution, Genetic Basis, And Variation Across Habitats, Angela Tringali

Electronic Theses and Dissertations

Ornamental traits are considered honest advertisements of fitness, and their evolution is usually explained in terms of sexual selection. This explanation remains unsatisfactory in some instances, for example, juvenile birds whose plumage is molted prior to adulthood and breeding. I first evaluate whether juvenile plumage reflectance signals dominance status in the Federally Threatened Florida scrub-jay (Aphelocoma coerulescens) using a combination of observational and experimental methods. Then I estimate the heritability, non-genetic maternal and environmental effects, and strength of selection on juvenile plumage reflectance using archived feather samples and a pedigree constructed from historical nest records. Finally, I compare plumage reflectance …

Aerobic Exercise As A Means Of Reducing Low Back Pain A Systematic Review, Theresa Privett

HIM 1990-2015

Background: Low back pain (LBP) is considered the leading cause of inactivity and lost employment time. It can be extremely difficult to treat as most conventional therapies have poor success rates. People with LBP need to be made more aware of the diverse and economical treatments available in order to save on expenses and diminish stress. Patients and healthcare professionals have many choices when deciding on the best plan of care; however, it is often difficult to determine which option is best. Objectives: The purpose of this systematic review was to determine if aerobic exercises play a role in reducing …

Yoga As A Treatment For Low Back Pain A Systematic Review Of Randomized Controlled Trials, Alison Diaz

Yoga is the most widely used complementary and alternative medicine treatment for low back pain and it is not fully certain how effective this method is for resolving the symptoms. Objectives: The purpose of this manuscript is to systematically review the current literature for randomized controlled trials that assess the outcomes of yoga intervention in individuals with low back pain. Methods: An electronic database search was performed to analyze …

The Effects Of Urbanization On Cypress (Taxodium Distichum) In Central Florida, Lisa A. Mccauley

Electronic Theses and Dissertations

Urbanization is accelerating in the United States and is contributing to fragmentation of natural habitats, causing changes in species composition and declines in native species. Human population growth in Orlando is typical of growth in the southeastern United States and throughout the range of cypress (Taxodium distichum). Orlando has numerous isolated cypress wetlands, called cypress domes, and many remain among the current urbanized area. This makes Orlando ideal to study the effects of urbanization on cypress domes. Specifically, I tested how urbanization and its effects on fragmentation, hydrology, and fire regime) affected (a) the numbers and spatial pattern of cypress …

Treefrog (Hyla Squirella) Responses To Rangeland And Management In Semi-Tropical Florida, Usa, Kathryn Windes

Electronic Theses and Dissertations

As urban areas expand, agricultural lands become increasingly important habitat for many species. Compared to some types of agricultural land-use, ranchlands provide vast expanses of minimally modified habitat that support many threatened and endangered species. Conservation biologists can promote ecologically sound management approaches by quantifying the effects of agricultural practices on resident species. I examined the effects of pasture management, cattle grazing, and landscape characteristics on both adult and larval treefrogs in a ranchland in south-central Florida. I experimentally determined optimal deployment of artificial treefrog shelters constructed of polyvinylchloride (PVC) pipe to efficiently sample adult treefrogs (Chapter 1). Seventy-two shelters …

Students' Perceptions Of Collaboration Tools In A Higher Education Online Collaborative Learning Environment, Kirk Henry

Electronic Theses and Dissertations

Higher education funding and student behavior has been changing rapidly (Dervarics,2008). Because of this, there has been an increased focus on the use of alternative tools for course delivery. One of the emerging areas of focus has been an increased interest in the use of communication and information technologies (Curtis & Lawson, 2001). Currently, there are a wide variety of flexible delivery methods that have been used as well as their associated tools. Naturally, questions have been raised about the efficacy of these tools on the quality of student-student, student-teacher, and student-content interaction (Curtis & Lawson, 2001). Interaction and Collaboration …

A Model Of Flow And Play In Game-Based Learning The Impact Of Game Characteristics, Player Traits, And Player States, Davin Pavlas

Electronic Theses and Dissertations

In this dissertation, the relationship between flow state, serious games, and learning was examined. Serious games, which are games that convey something other than enjoyment (e.g., learning), are increasingly popular platforms for research, training, and advertisement. The elements that make serious games useful to researchers, trainers, and practitioners are closely linked to those that make up the positive psychology construct of flow state. Flow state describes an optimum experience that is encountered when a variety of factors are met, and is characterized by high focus, engagement, motivation, and immersion. While flow state is often discussed in the serious games literature, …

Critical Success Factors In Florida's Bed And Breakfast Industry, Catherine I. Rash

HIM 1990-2015

Florida bed and breakfasts (B&Bs) were surveyed for the purpose of discovering the attitudes, beliefs, and actual behaviors of B&B owners and operators that contribute to an operation’s success. This study had several objectives: 1) to provide an analysis of attitudes and beliefs perceived to be necessary for success and the actual behaviors exhibited by operators based upon their self-definition of success, 2) to collect demographic information from various bed and breakfasts in Florida, and 3) to expand the limited amount of research that has addressed issues in the bed and breakfast industry. Between July 2009 and August 2009, data …

Landcover Change And Population Dynamics Of Florida Scrub-Jays And Florida Grasshopper Sparrows, David Breininger

Electronic Theses and Dissertations

I confronted empirical habitat data (1994-2004) and population data (1988-2005) with ecological theory on habitat dynamics, recruitment, survival, and dispersal to develop predictive relationships between landcover variation and population dynamics. I focus on Florida Scrub-Jays, although one chapter presents a model for the potential influence of habitat restoration on viability of the Florida Grasshopper Sparrow. Both species are unique to Florida landscapes that are dominated by shrubs and grasses and maintained by frequent fires. Both species are declining, even in protected areas, despite their protected status. I mapped habitat for both species using grid polygon cells to quantify population potential …

Art Therapy Treatment With Incarcerated Women, Bonnie Erickson

Electronic Theses and Dissertations

This study examined the effectiveness of art therapy in decreasing symptoms of trauma and psychological distress in women who were incarcerated in county jails in the Southeastern United States. In order to protect the integrity of the study, control subjects were in different dormitories from the treatment subjects. While the dormitories were randomly assigned to treatment or control, the subjects were not. The dependent measures were paper and pencil tests, the Outcome Questionnaire (OQ-45.2) and the Trauma Symptom Inventory (TSI) given at pretest and posttest. A demographic questionnaire was completed in the first session to better characterize the participants. In …

Does Habitat Affect Clonal Demography? An Experiment With Polygonella Myriophylla In Roadside And Florida Scrub, Kristina Dianne Horn

Electronic Theses and Dissertations

Polygonella myriophylla (Polygonaceae) is a clonal shrub listed as endangered and narrowly endemic to pyrogenic scrub ecosystems in central Florida. It is almost restricted to gaps within the matrix of shrubs in the scrub but also occurs along adjacent road-side habitats. I hypothesize that persistent disturbed microhabitats and more dynamic sand accretion in roadsides will increase rooting probabilities compared to more stable scrub habitats, affecting survival, growth and reproduction. In April 2004- March 2006, I compared plant (genet) and basal branch (ramet) performance between experimentally manipulated plants in native scrub and roadside habitats at two locations within the Lake Wales …

Demographic Consequences Of Managing For Florida Scrub-Jays (Aphelocoma Coerulescens) On An Isolated Preserve., Casey Lyon

Electronic Theses and Dissertations

Many species naturally occupy discrete habitat patches within a mosaic of habitats that vary in quality. The Florida scrub-jay (Aphelocoma coerulescens) is endemic to Florida scrub, a habitat that is naturally patchy and greatly reduced in area over recent decades owing to development and urbanization. Because of this habitat loss, future management of Florida scrub-jays will focus on smaller, fragmented tracts of land. My study examines such a tract, Lyonia Preserve, southwest Volusia County, FL. This preserve was unoccupied by scrub-jays prior to habitat restoration. The preserve is now frequently managed exclusively for scrub-jays as a habitat island surrounded by …

A Demographic Study Of An Isolated Population Of The Gopher Tortoise, Gopherus Polyphemus; And An Assessment Of A Relocation Procedure For Tortoises, Terry J. Doonan

Retrospective Theses and Dissertations

It is acknowledged that the gopher tortoise is declining in numbers throughout its geographic range primarily from degradation and loss of suitable habitat. This research project is part of a pilot program to study the effectiveness of relocation as a mitigation method for the conservation of gopher tortoises. There was an opportunity to gather information about the tortoise population prior to its relocation, and for that reason this thesis is presented in two sections.

The first section of this work involved the analysis of the tortoise population prior to its removal from the development site. Results of two methods for …

Nonverbal Communication Of The Deaf, Jayne S. Lytle

Association for Communication Administration Bulletin

Nonverbal communication among deaf people is discussed in relation to American Sign Language, Deaf culture, and interactions between deaf and hearing people. The article distinguishes between nonverbal behavior and the visual linguistic features of ASL, noting that movements of the face, eyes, head, and body may function as part of the language rather than as merely expressive gestures. It reviews assumptions about deaf people’s receptive and expressive nonverbal abilities, including the idea that visual communication automatically produces greater skill in interpreting body language. The article describes characteristic behaviors related to proxemics, touch, attention-getting gestures, eye gaze, and paralanguage, with attention …
