Articulating Social Change In Puerto Rico: Environmental Education As A Model For Youth Socio-Political Development And Community-Led School Reform, Federico Cintrón-Moscoso Apr 2010

Articulating Social Change In Puerto Rico: Environmental Education As A Model For Youth Socio-Political Development And Community-Led School Reform, Federico Cintrón-Moscoso

USF Tampa Graduate Theses and Dissertations

Recent attempts at developing an environmental education agenda in public schools emphasize the need to foster greater public awareness about environmental rights, issues, and solutions, while producing citizens with the knowledge and skills needed to address the ecological challenges of contemporary society. However, some scholars have argued that the attempt to integrate environmental principles into the school curricula has created a conflict between the politically-oriented goals of environmental education and the more passive practices of uncritical assimilation and reproduction found in many schools today (Stevenson 2007). Moreover, although there is a need for public schools to take on the challenge …


Predicting Early Adolescents’ Academic Achievement And In-School Behavior With A Dual-Factor Model Of Mental Health, Amanda L. Thalji Apr 2010

Predicting Early Adolescents’ Academic Achievement And In-School Behavior With A Dual-Factor Model Of Mental Health, Amanda L. Thalji

USF Tampa Graduate Theses and Dissertations

A dual-factor model of mental health includes indicators of wellness (i.e., subjective well-being) and psychopathology (i.e., internalizing and externalizing behavior problems) in defining psychological wellness. The present empirical investigation examined the utility of SWB and psychopathology examined separately and together (as in a dual-factor model of mental health) in predicting students' subsequent academic achievement and in-school behavior. Specifically, it determined if SWB, psychopathology, and membership in a specific mental health group yielded by the dual-factor model (i.e., complete mental health, vulnerable, symptomatic but content, or troubled) at Time 1 was related to achievement (i.e., GPA, FCAT-math, FCAT-reading, absences, office disciplinary …


Descartes' Bête Machine, The Leibnizian Correction And Religious Influence, John Voelpel Apr 2010

Descartes' Bête Machine, The Leibnizian Correction And Religious Influence, John Voelpel

USF Tampa Graduate Theses and Dissertations

René Descartes’ 1637 “bête machine” characterization of nonhuman animals has assisted in the strengthening of the Genesis 1:26 and 1: 28 disparate categorization of nonhuman animals and human animals. That characterization appeared in Descartes’ first important published writing, the Discourse on the Method, and can be summarized as including the ideas that nonhuman animals are like machines; do not have thoughts, reason or souls like human animals; and thus, cannot be categorized with humans; and, as a result, do not experience pain or certain other feelings. This characterization has impeded the primary objective of environmental ethics - the extension of …


Comparing The Effectiveness Of Behavioral Contracts That Use Function Based Reinforcers Versus Highly Preferred Items For Attention Maintained Behaviors, Dánica M. Diáz Apr 2010

Comparing The Effectiveness Of Behavioral Contracts That Use Function Based Reinforcers Versus Highly Preferred Items For Attention Maintained Behaviors, Dánica M. Diáz

USF Tampa Graduate Theses and Dissertations

Behavioral contracts were used to reduce the socially inappropriate and stigmatizing behaviors of adult men diagnosed with an intellectual disability. All three participants were residing in an intensive residential habilitation facility and receiving 24 hour supports due to the intensity of their problem behaviors. A multiple baseline across subjects with a series of reversals within the intervention phase was used to compare and evaluate the effectiveness of two types of behavioral contracts: one based on the function of the behavior and the other based on highly preferred items. Brief functional analyses were conducted to determine the function of the participants' …


Design And Evaluation Of A Green Bittorrent For Energy-Efficient Content Distribution, Jeremy H. Blackburn Apr 2010

Design And Evaluation Of A Green Bittorrent For Energy-Efficient Content Distribution, Jeremy H. Blackburn

USF Tampa Graduate Theses and Dissertations

IT equipment has been estimated to be responsible for 2% of global CO2 emissions and data centers are responsible for 1.2% of U.S. energy consumption. With the large quantity of high quality digital content available on the Internet the energy demands and environmental impact of the data centers must be addressed. The use of peer-to-peer technologies, such as BitTorrent, to distribute legal content to consumers is actively being explored as a means of reducing both file download times and the energy consumption of data centers. This approach pushes the energy use out of the data centers and into the homes …


Shape And Pose Recovery Of Novel Objects Using Three Images From A Monocular Camera In An Eye-In-Hand Configuration, Steven C. Colbert Apr 2010

Shape And Pose Recovery Of Novel Objects Using Three Images From A Monocular Camera In An Eye-In-Hand Configuration, Steven C. Colbert

USF Tampa Graduate Theses and Dissertations

Knowing the shape and pose of objects of interest is critical information when planning robotic grasping and manipulation maneuvers. The ability to recover this information from objects for which the system has no prior knowledge is a valuable behavior for an autonomous or semiautonomous robot. This work develops and presents an algorithm for the shape and pose recovery of unknown objects using no a priori information. Using a monocular camera in an eye-in-hand configuration, three images of the object of interest are captured from three disparate viewing directions. Machine vision techniques are employed to process these images into silhouettes. The …


Immune Redistribution To Skin In Wild And Domesticated Songbirds, Joshua Ryan Kuhlman Apr 2010

Immune Redistribution To Skin In Wild And Domesticated Songbirds, Joshua Ryan Kuhlman

USF Tampa Graduate Theses and Dissertations

Implantation of dental sponges under the skin of lab rodents has been used to evaluate whether acute stress enhances leukocyte infiltration to a surgical site. First, I replicated this technique in house sparrows to test whether transient stressors cause similar immunoredistribution (i.e., movement of immune cells out of circulation and to the periphery) in a wild animal. As placement into captivity alone may serve as a stressor to wild animals, I compared sponge infiltration over different periods of captivity. Second, I compared how domestication affects immunoredistribution by comparing results of wild sparrows to domesticated zebra finches. Zebra finches were chosen …


Spanish Spelling Errors Of Emerging Bilingual Writers In Middle School, Diana Julbe-Delgado Apr 2010

Spanish Spelling Errors Of Emerging Bilingual Writers In Middle School, Diana Julbe-Delgado

USF Tampa Graduate Theses and Dissertations

In spite of the significant growth in the Spanish-English bilingual population, there has not been sufficient research on cross-language effects, or how language transfer may affect important components of literacy, such as spelling. Many studies have focused on the influence of Spanish on the acquisition of English spelling skills; however, few studies have focused on how the acquisition of English influences Spanish spelling. The purpose of this investigation was to study the spelling errors of bilingual adolescents as they learn English.

A total of 20 bilingual Spanish-English students in grades 6 through 8 (ages 11 to 14 years) were selected …


A Philosophical Inquiry On The Valuation And Selection Of Musical Materials For Culturally Diverse Learners In Global Environments, Jonathan Bassett Apr 2010

A Philosophical Inquiry On The Valuation And Selection Of Musical Materials For Culturally Diverse Learners In Global Environments, Jonathan Bassett

USF Tampa Graduate Theses and Dissertations

The selection of musical materials for use in the classroom is problematic. Since music educators have limited time with students, the inclusion of musical materials necessitates the perceived exclusion of other musical materials. This perception is due in part to the increasing diversity of students represented in the classroom, the cultural labeling of musical materials, the influence of multiculturalism on music education, and the influence of the Western aesthetic in music education. Since diverse groups can and do propose socially perceived valuations of these materials as critical for the inclusion of specific musical materials for use in the classroom, this …


Parallel Genetic Algorithm Engine On An Fpga, Mark La Spina Apr 2010

Parallel Genetic Algorithm Engine On An Fpga, Mark La Spina

USF Tampa Graduate Theses and Dissertations

The field of FPGA design is ever-growing due to costs being lower than that of ASICs, as well as the time and cost of development. Creating programs to run on them is equally important as developing the devices themselves. Utilizing the increase in performance over software, as well as the ease of reprogramming the device, has led to complex concepts and algorithms that would otherwise be very time-consuming when implemented on software. One such focus has been towards a search and optimization algorithm called the genetic algorithm. The proposed approach is to take an existing application of the genetic algorithm …


Biosynthesis Of Fatty Acid Amides, Emma K. Farrell Apr 2010

Biosynthesis Of Fatty Acid Amides, Emma K. Farrell

USF Tampa Graduate Theses and Dissertations

Primary fatty acid amides (PFAMs) and N-acylglycines (NAGs) are important signaling molecules in the mammalian nervous system, binding to many drug receptors and demonstrating control over sleep, locomotor activity, angiogenesis, vasodilatation, gap junction communication, and many other processes. Oleamide is the best-studied of the PFAMs, while the in vivo activity of the others is largely unstudied. Even less is known about the NAGs, as their discovery as novel compounds is much more recent due to low endogenous levels. Herein is described extraction and quantification techniques for PFAMs and NAGs in cultured cells and media using solvent extraction combined with …


Re-Composition: Considering The Intersections Of Composition And Creative Writing Theories And Pedagogies, Danita Berg Apr 2010

Re-Composition: Considering The Intersections Of Composition And Creative Writing Theories And Pedagogies, Danita Berg

USF Tampa Graduate Theses and Dissertations

Maintaining composition studies and creative writing as discrete disciplines may not be in the best interests of either field. But so long as the majority of scholars and practitioners of either field remain largely uninformed about one another, it is unlikely that any progress toward conjoining the two fields will occur. Various important and constructive efforts have been made for more than thirty years to establish a scholarly, interdisciplinary community that dedicates itself to examining points of intersection between composition and creative writing. Initially, such efforts appear to attract the attention from the broader communities of each discipline. Before long, …


Do You Have A Permit For That? Exposing The Pseudo-Public Space And Exploring Alternative Means Of Urban Occupation, Adam Barbosa Apr 2010

Do You Have A Permit For That? Exposing The Pseudo-Public Space And Exploring Alternative Means Of Urban Occupation, Adam Barbosa

USF Tampa Graduate Theses and Dissertations

In his 1964 work "One Dimensional Man" Herbert Marcuse describes what he believes to be the de-evolution of industrialized society into the single minded pursuit of commerce. Decades later his hypothesis seems even closer to the truth, as much of our social interaction is now based in spaces that are designed to promote consumption. These spaces are in fact privately owned lots masquerading as public space so as to satiate the populace's desire for "public" interaction without sacrificing their effectiveness as places of commerce. The migration of social interaction into these pseudo-public spaces has also further marginalized the city's remaining …


The Effects Of Learning-Styles Information On The Achievement Of Community College Developmental Math Students, Kevin A. Hoeffner Apr 2010

The Effects Of Learning-Styles Information On The Achievement Of Community College Developmental Math Students, Kevin A. Hoeffner

USF Tampa Graduate Theses and Dissertations

Four out of five Americans will require some postsecondary education. Therefore, a majority of population will return to a community college for retraining and personal growth (McCabe, 2003). Since the turn of this century, many studies have been conducted to examine the success and challenges of the relatively new community college system. One of the most significant challenges is the large percentage of the U.S. population requiring remedial coursework. Fifty-five percent of students entering Florida's postsecondary system require remediation. Of this large remedial population, only 51% will complete their preparatory classes. Students who do complete classes take an average of …


Alien Encounters And The Alien/Human Dichotomy In Stanley Kubrick‘S 2001: A Space Odyssey And Andrei Tarkovsky‘S Solaris, Keith Cavedo Apr 2010

Alien Encounters And The Alien/Human Dichotomy In Stanley Kubrick‘S 2001: A Space Odyssey And Andrei Tarkovsky‘S Solaris, Keith Cavedo

USF Tampa Graduate Theses and Dissertations

The alien encounter has long been a defining and popular subject of science fiction cinema. However, Stanley Kubrick's 2001: A Space Odyssey (1968) and Andrei Tarkovsky's Solaris (1972) are interrogative, complex, and distinct artistic accomplishments that stand apart from and above the conventional science fiction film. 2001 and Solaris not only represent but complicate the alien/human dichotomy; in the end, they destabilize the dichotomy and even suggest a radical synthesis of the dichotomous elements. 2001 and Solaris further emphasize epistemological and specifically anthropocentric limitations when it comes to understanding the alien or attempting to make sense of the alien encounter. …


Development And Testing Of A New C-Based Algorithm To Control A 9-Degree-Offreedom Wheelchair-Mounted-Robotic-Arm System, Ana Catalina Torres Rocco Apr 2010

Development And Testing Of A New C-Based Algorithm To Control A 9-Degree-Offreedom Wheelchair-Mounted-Robotic-Arm System, Ana Catalina Torres Rocco

USF Tampa Graduate Theses and Dissertations

A Wheelchair-Mounted Robotic Arm (WMRA) was designed to aid people with limited or no upper-limb usage to accomplish activities of daily living (ADLs). The primary objective of this research was to enhance the performance of the WMRA by improving the communication protocols and functions between the hardware and software used for its control.

Previously, the control algorithm of the robotic arm was tested in simulation and in the physical arm. These implementations required a combination of Matlab and C++ language and introduced some software instability under Windows operating system. To improve the performance of the WMRA, the programs for hardware …


Low Documented Risk Cesarean Sections And Late-Preterm Births: The Florida Experience, Heather Breeze Clayton Mar 2010

Low Documented Risk Cesarean Sections And Late-Preterm Births: The Florida Experience, Heather Breeze Clayton

USF Tampa Graduate Theses and Dissertations

There are increasing concerns about the excessive use of cesarean delivery in the United States, as cesarean deliveries have been associated with adverse maternal and infant health outcomes. Currently, the cesarean section (C/S) rate for Florida is the second highest in the nation. Furthermore, preliminary reports from the Florida Department of Health (FDOH) have implicated the increasing rate of cesarean delivery to an increase in the rate of late preterm births (PTB) in Florida (births at 34 to 36 weeks gestational age). Information on the impact of late PTB associated with cesarean delivery on the rate of maternal and infant …


Lived Experience: Near-Fatal Adolescent Suicide Attempt, Phyllis Ann Dougherty Mar 2010

Lived Experience: Near-Fatal Adolescent Suicide Attempt, Phyllis Ann Dougherty

USF Tampa Graduate Theses and Dissertations

Adolescent suicide has become a national health crisis. Suicide now ranks as a leading cause of adolescent death in the U.S. In response to this, the National Strategy for Suicide Prevention (2001b) recommended the promotion and support of research into suicide and prevention, particularly high-risk groups such as adolescents. However, due to concerns for safety and liability, there have been few studies of highly suicidal individuals, specifically adolescents. Leading suicidologists have agreed that studying the qualities of the near-fatal suicide attempt can most resemble the completed suicide.

This case study explored the phenomenon of the near-fatal suicide attempt through the …


Active Surface Topographies In Constrained Hydrogel Films For Biomedical Applications, Ophir Ortiz Mar 2010

Active Surface Topographies In Constrained Hydrogel Films For Biomedical Applications, Ophir Ortiz

USF Tampa Graduate Theses and Dissertations

Lung cancer has the highest mortality rate relative to all types of cancers, and unfortunately there still exist numerous challenges towards decreasing this rate. One of these challenges is gaining a clear understanding of why metastatic lung cancer cells attach and detach to colonize other areas of the body. Reports suggest that the attachment of cells to secondary tumor sites does not occur randomly. It is theorized that both the physical and chemical properties of the tissue are able to create a suitable environment for their adhesion. Therefore, the motivation for the work presented herein is to use dynamic thermoresponsive …


Noise And Multipath Characteristics Of Power Line Communication Channels, Hasan Basri Çelebi Mar 2010

Noise And Multipath Characteristics Of Power Line Communication Channels, Hasan Basri Çelebi

USF Tampa Graduate Theses and Dissertations

With the recent developments in technology, information and communication technologies (ICTs) are becoming more widespread and one of the basic building blocks of every humans life. The increasing demand in broadband communication calls for new technologies. Power line communication (PLC) is one of the potential candidates for next generation ICTs. Although communication through power lines has been investigated for a long time, PLC systems were never taken into account seriously because of its harsh communication medium. However, with the development of more robust data transmission schemes, communication over the power lines is becoming a strong alternative technology because of the …

Experiences Of Foreign Language Teachers And Students Using A Technology-Mediated Oral Assessment, Jeannie Ducher Mar 2010

Experiences Of Foreign Language Teachers And Students Using A Technology-Mediated Oral Assessment, Jeannie Ducher

USF Tampa Graduate Theses and Dissertations

The development of the speaking skill at the lower levels of proficiency is seldom assessed as a matter-of-fact in the foreign language classroom, for reasons of impracticality and difficulty of implementation. Although the practice of the speaking skill is an important part of current approaches to the teaching of foreign languages, issues of time and logistics often prohibit the direct evaluation of the skill in a manner consistent with best practices, which purport that practice and assessment must be closely aligned, and that students benefit from self-evaluation and teacher feedback. Classroom research has shown that a skill that is not …

Manifestations Of Hidden Curriculum In A Community College Online Opticianry Program: An Ecological Approach, Barry Hubbard

USF Tampa Graduate Theses and Dissertations

Understanding the influential factors at work within an online learning environment is a growing area of interest. Hidden or implicit expectations, skill sets, knowledge, and social process can help or hinder student achievement, belief systems, and persistence. This qualitative study investigated how hidden curricular issues transpired in an online learning environment's institutional and organization systems using an ecological paradigm. A phenomenological approach rooted in a case study context was used to explore the experiences and perceptions of a group of students, faculty, and administrators involved with an online academic program (opticianry) at a community college. Interviews, non-participant observation, and a …


An Interpretive Policy Analysis Of Bullying Law And The Development Of Bullying Policy In A Central Florida School District, Scott D. Richman Mar 2010

An Interpretive Policy Analysis Of Bullying Law And The Development Of Bullying Policy In A Central Florida School District, Scott D. Richman

USF Tampa Graduate Theses and Dissertations

Bullying has been an issue in schools and became a major concern for school leaders over the past two decades. Olweus (1993) defined three characteristics of bullying behavior: intent to harm another, repeated offenses, and a perceived or real power imbalance. This study examined the law's provisions concerning bullying in schools; specifically examining the Florida Jeffrey Johnston Stand Up for All Student Act (2008), and the required policy implemented in Hillsborough County Public Schools (HCPS). Discourse theory framed the study, as defined by Habermas (1996) and the derivative Interpretive Policy Analysis was used to analyze the district policy, as defined …


Writing To (Re)New Orleans: The Post-Hurricane Katrina Blogosphere And Its Ability To Inspire Recovery, Daisy Pignetti Mar 2010

Writing To (Re)New Orleans: The Post-Hurricane Katrina Blogosphere And Its Ability To Inspire Recovery, Daisy Pignetti

USF Tampa Graduate Theses and Dissertations

Nearly every website or software application these days features a feed to subscribe to, a network to join, or a social timeline to track—all of which do their part to influence public opinion, promote products, and bring people closer together. Being a blogger since 2003 exposed me to these user-generated trends, but never did I expect my blog space, or any others, to play such an important role in my emotional well-being; not until Hurricane Katrina hit. Sharing my story as a transplanted New Orleanian watching the disaster unfold from afar in a public forum quickly linked me to other …


School Psychologists Involvement And Perceived Preparedness In The Provision Of Suicide-Related Services: A Comparison Of Practitioners Serving Different School Levels, Jennifer M. Cunningham Mar 2010

School Psychologists Involvement And Perceived Preparedness In The Provision Of Suicide-Related Services: A Comparison Of Practitioners Serving Different School Levels, Jennifer M. Cunningham

USF Tampa Graduate Theses and Dissertations

While the manifestation of suicidal thoughts and/or behavior is more common among adolescents, children are capable of, and do experience, suicidal ideation as well as demonstrate suicidal behaviors. Suicide is the sixth leading cause of death among children aged 5-14 years (Center for Disease Control [CDC], 2008). However, children may not always be referred or brought to the attention of the school psychologist, as their threats may be considered immature and unfounded. The purpose of this study is to provide data that clarifies the need for the provision of suicide-related services for children in elementary school. An archival dataset of …


The Rebirth Of A Semi-Disintegrated Enterprise: Towards The Future Of Composites In Pre-Synthesized Domestic Dwellings; And The Societal Acceptance Of The Anti-In Situ Architectural Movement, Timothy James Keepers Mar 2010

The Rebirth Of A Semi-Disintegrated Enterprise: Towards The Future Of Composites In Pre-Synthesized Domestic Dwellings; And The Societal Acceptance Of The Anti-In Situ Architectural Movement, Timothy James Keepers

USF Tampa Graduate Theses and Dissertations

The prefabricated home has been said to be the site of innovation, exploration and sometimes spectacular failure since the mid 20th-century (Home Delivery, 8). Despite years of research and advancements in technology, pre-synthesization in the domestic realm has typically remained loyal to past construction methods/materials and banal aesthetic ripostes. As a result, the modern pre-synthesized home suffers in terms of programmatic diversity, spatial feedback, supertemporal expansion (in reference to the supertemporal art movement) and societal acceptance.

Materials and technologies are constantly upgrading in our increasingly technetronic society. Re-marketing the prefabricated home will require a similar modus operandi. Investigating the successes …


Exploring Colorectal Cancer Diagnosis Disclosure To First-Degree Relatives: An African American Family Case Series, Kamilah B. Thomas Mar 2010

Exploring Colorectal Cancer Diagnosis Disclosure To First-Degree Relatives: An African American Family Case Series, Kamilah B. Thomas

USF Tampa Graduate Theses and Dissertations

Colorectal cancer (CRC) is the second leading cancer killer in the United States and the third most common cancer in African American men and women. Though the overall death rates have declined, this reduction in mortality is smaller for African Americans than for Whites. Factors that are protective against colorectal cancer include occupational or recreational physical activity, a diet high in fruits and vegetables, and colorectal cancer screening with removal of polyps (polypectomy) before they progress to cancer. Compliance with CRC screening recommendations requires people to know if a first-degree relative (parent, sibling, and child) or second-degree relative (aunt, uncle, …


System Identification In Automatic Database Memory Tuning, Tiffany Burrell Mar 2010

System Identification In Automatic Database Memory Tuning, Tiffany Burrell

USF Tampa Graduate Theses and Dissertations

Databases are very complex systems that require database system administrators to perform system tuning in order to achieve optimal performance. Memory tuning is vital to the performance of a database system because when the database workload exceeds its memory capacity, the results of the queries running on a system are delayed and can cause substantial user dissatisfaction. In order to solve this problem, this thesis presents a platform modeled after a closed control feedback loop to control the level of multi-query processing. Utilizing this platform provides two key assets. First, the system identification is acquired, which is one of two …


Imagined Realities, Defying Subjects: Voice, Sexuality And Subversion In African Women's Writing, Sarah Namulondo Mar 2010

Imagined Realities, Defying Subjects: Voice, Sexuality And Subversion In African Women's Writing, Sarah Namulondo

USF Tampa Graduate Theses and Dissertations

The privileging of man in African societies has involved an erasure of identities and subjectivities of many women, holding them to an assumption of female inferiority. To counter the injustice, African women writers have engaged in rhetorical and performative strategies designed to reconstitute the cultural erasure as they try to claim status as individuals. But in the process, various cultural expectations such as their maternal roles act as constant bottlenecks to return them back to their prescribed roles as subordinate beings. This dissertation, “Imagined Realities, Defying Subjects: Voice, Sexuality and Subversion in African Women’s Writing” explores the methodologies of cultural …
