Accuracy Of Educator Nominations In Identifying Students With Elevated Levels Of Anxiety And Depression, Jennifer Cunningham Oct 2011

Accuracy Of Educator Nominations In Identifying Students With Elevated Levels Of Anxiety And Depression, Jennifer Cunningham

Graduate Theses and Dissertations

Internalizing disorders, specifically depression and anxiety, affect up to 18% and 33% of youth, respectively (Costello, Egger, & Angold, 2005b). Schools have become a major provider of mental health services to children, primarily in attempts to overcome barriers to receiving community services (Farmer, Burns, Philip, Angold, & Costello, 2003). As such, it is important that schools have effective mechanisms in place to accurately identify students who may be in need of such services. The current study examined the accuracy of one such method, educator nominations (including from both teachers and school-based mental health professionals) in identifying students who self-report elevated levels of anxiety and/or depression. Participants were 238 fourth and fifth grade students within a large, urban school district in a southeastern state; 26 classroom teachers of these youth; and 7 mental health professionals who served the two schools that the student participants attended. Regarding sensitivity, teachers identified 40.74% and 50% of students who repeatedly reported clinically elevated levels of anxiety and depression, respectively. Teachers falsely identified as symptomatic 17.54% and 16.2% of students with typical levels of anxiety and depression, respectively. As a team, school-based mental health professionals identified 66.67% of students with elevated anxiety symptoms, and 45.45% of children ...


An Observation Of Immunological Effect, A Diet Enhanced With Spirulina And Treatment With Fractalkine In Models Of Parkinson's Disease, Mibel Pabón May 2011

An Observation Of Immunological Effect, A Diet Enhanced With Spirulina And Treatment With Fractalkine In Models Of Parkinson's Disease, Mibel Pabón

Graduate Theses and Dissertations

In my dissertation research we used use human wild type α-synuclein gene expression using an adeno-associated viral vector (AAV9) that induced a slowly progressive loss of dopamine (DA) neurons in the Substantia nigra (SN) as one of our animal model of Parkinson’s disease (PD). It is our hypothesis that neuroinflammation predisposes the brain to susceptibility to neurodegenerative diseases. Thus we examined the progression of a PD lesion and examined the manipulations of the immune system to understand further the inflammatory role when we administered exogenous soluble fractalkine.

The specific etiology of neurodegeneration in PD is unknown, but the inflammatory ...


Discovery Of A Functional Ecdysone Response Element In Brugia Malayi, Tracy Enright May 2011

Discovery Of A Functional Ecdysone Response Element In Brugia Malayi, Tracy Enright

Graduate Theses and Dissertations

The aim of this study was to determine whether functional ecdysone response elements (EcREs) exist within the genome of Brugia malayi, a parasitic nematode that causes lymphatic filariasis. The hypothesis that EcREs exist in B. malayi stemmed from previous demonstration of a functional ecdysone response system in B. malayi (Tzertzinis et al., 2010). Real-time PCR (qPCR) experiments were conducted to measure gene expression levels for twelve genes proximal to five putative EcREs in 20-OH ecdysone treated and untreated B. malayi embryos. Seven genes showed consistent upregulation with 20-OH ecdysone treatment. Each of the five putative EcREs had at least one ...


Aging With Independence And Interaction: An Assisted Living Community, Steven J. Flositz Apr 2011

Aging With Independence And Interaction: An Assisted Living Community, Steven J. Flositz

Graduate Theses and Dissertations

As the U.S. population gets older, there is an increased need for senior housing. However, elderly housing is currently associated with dependence and isolation. There is a great disconnect from the retired community with its surrounding context. Senior housing and nursing homes are becoming more similar to miniature hospitals rather than a residential type. This negative view of nursing homes is becoming clear to the general population. In fact, most seniors fear the idea of living within an aging complex. Also, people generally avoid these places, even while visiting family. Florida is on the frontline for the effects of ...


Historical Archaeology Of The Pine Level Site (8de14), Desoto County, Florida, Jana Futch Mar 2011

Historical Archaeology Of The Pine Level Site (8de14), Desoto County, Florida, Jana Futch

Graduate Theses and Dissertations

In 1866 the seat of Manatee County was moved to Pine Level, a newly-formed town in the wilderness of south Florida. By the 1880s, it contained stores, boardinghouses, churches, and government buildings. In 1887, Pine Level became DeSoto County’s first seat. However, when it lost county seat status to Arcadia only 18 months later, in 1888, Pine Level rapidly declined in population and importance, and eventually died out. The investigations of the Pine Level site detailed in this thesis were carried out as a public archaeology project, involving the DeSoto County Historical Society, University of South Florida, and the ...


Designing Identities For "Green" Industries, Beverly Lynn Krumm Jan 2011

Designing Identities For "Green" Industries, Beverly Lynn Krumm

Graduate Theses and Dissertations

There has been resurgence in the social significance of sustainability with the recent concerns of global warming, although sustainability is not a new idea. Environmental concerns began on a national level in 1970, but it is again a `hot' topic, and businesses want the appearance of being ecologically friendly. It has become fashionable to be "green" or to give the appearance of being "green."

A visual identity does more than represent a company, product, or service; they trigger emotions, create desires and forge communities. A logo is just one element of a corporate identity system, but it is arguably one ...

Brazilian English As Foreign Language Teachers' Beliefs About Grammar-Based Feedback On L2 Writing, Katia Silene Ferreira De Mello Paiva Jan 2011

Brazilian English As Foreign Language Teachers' Beliefs About Grammar-Based Feedback On L2 Writing, Katia Silene Ferreira De Mello Paiva

Graduate Theses and Dissertations

Empirical findings have suggested that what teachers do in the classroom mirrors what they believe and these beliefs often influence their instructional decisions (Farrell & Lim, 2005). Research in teacher belief is vast and diverse (Borg, 2003) as is investigation about the effectiveness of written corrective feedback per se (Ferris, 2006; Truscott, 2009); however, little is known about teachers' beliefs about written corrective feedback (Lee, 2009). Therefore, this study aimed at investigating Brazilian EFL teachers' beliefs about grammar-based feedback on L2 writing and the extent to which their beliefs are related to their perceived classroom practice. Fifteen Brazilian EFL teachers answered a five-point Likert scale survey. Results suggest that Brazilian teachers tend to believe that form-focused correction is a recommendable instructional approach. In addition, the qualitative analysis ...


Small Flowerings Of Unhu: The Survival Of Community In Tsitsi Dangarembga's Novels, Dana Rine Jan 2011

Small Flowerings Of Unhu: The Survival Of Community In Tsitsi Dangarembga's Novels, Dana Rine

Graduate Theses and Dissertations

This thesis examines the presence of unhu, a process of becoming and remaining human through community ties, in Nervous Conditions and The Book of Not by Tsitsi Dangarembga. Dangarembga interrogates corrupt versions of community by creating positive examples of unhu that alternatively foster community building. Utilizing ecocritical, utopian, and postcolonial methodologies, this thesis postulates that these novels stress the importance of retaining a traditional concept like unhu while also acknowledging the need to adjust it over time to ensure its vitality. Both novels depict the creativity and resilience of unhu amid toxic surroundings.

Wisdom In The Earth: An Examination Of The History Of Intellectual Property Rights In Plants And Seeds, Kevin Frank Howe Jan 2011

Wisdom In The Earth: An Examination Of The History Of Intellectual Property Rights In Plants And Seeds, Kevin Frank Howe

Graduate Theses and Dissertations

Economic influences played a dominant role in design and implementation of intellectual property laws and agriculture policy in America. These influences have helped shape the values and goals of people who created, administered and interpreted patent laws throughout the twentieth century, as well as those who promoted agriculture in America and later in the developing world. The historical motivations driving these two institutions help explain how and why plants entered the realm of intellectual property and why international aid organizations defined and measured progress in economic terms. Events that serve to illustrate these dynamics include the Plant Patent Act of ...
