Fabrication And Characterization Of Electrospun Cactus Mucilage Nanofibers, Yanay Pais

USF Tampa Graduate Theses and Dissertations

This work seeks to fabricate, optimize, and characterize nanofibers of cactus Opuntia ficus-indica mucilage and Poly (vinyl alcohol) (PVA) by electrospinning. Mucilage is a neutral mixture of sugars produced by cactus and PVA is a non-toxic, water-soluble, synthetic polymer, which is widely used as a co-spinning agent for polymers. Mucilage was extracted from the cactus pad and prepared for electrospinning by mixing with acetic acid. Two types of PVA were used differentiating in high and low molecular weights. Concentrations of PVA were varied to find an adequate threshold for fiber formation. Changing the ratio of PVA to cactus mucilage produced …

Coupled Photonic Crystal Micro-Cavities With Ultra-Low Threshold Power For Stiumulated Raman Scattering, Qiang Liu, Zhengbiao Ouyang, Sacharia Albin

Electrical & Computer Engineering Faculty Publications

We propose coupled cavities to realize a strong enhancement of the Raman scattering. Five sub cavities are embedded in the photonic crystals. Simulations through finite-difference time-domain (FDTD) method demonstrate that one cavity, which is used to propagate the pump beam at the optical-communication wavelength, has a Q factor as high as 1.254 × 10⁸ and modal volume as small as 0.03μm³ (0.3192(λ/n)³). These parameters result in ultra-small threshold lasing power ~17.7nW and 2.58nW for Stokes and anti-Stokes respectively. The cavities are designed to support the required Stokes and anti-Stokes modal spacing in silicon. The proposed structure …

A Comparison Of Ecological Conditions And Relationships In An Altered Wetland And An Unaltered Wetland, Mark Kiyoshi Hurst

USF Tampa Graduate Theses and Dissertations

The purpose of the study is to identify and quantify the hydrologic and ecologic differences between two adjacent sections of Colt Creek; one section unaltered and one section altered by clearing and drainage. These differences were measured by monitoring water levels, groundcover vegetation in each of the two areas, and monitoring numbers and species of birds utilizing the two areas. Surface water levels were measured in three locations: in the historic Colt Creek flow way, in the ditch draining the creek, and in an adjacent wetland strand. In addition, a shallow monitor well in the creek was used to measure …

Assessing The Relationship Of Monocytes With Primary And Secondary Dengue Infection Among Hospitalized Dengue Patients In Malaysia, 2010: A Cross-Sectional Study, Benjamin Glenn Klekamp

USF Tampa Graduate Theses and Dissertations

Dengue, a group of four similar viruses transmitted through the bite of a mosquito, is estimated to infect upwards of 100 million annually in over 100 nations throughout the global equatorial belt. Distribution of global dengue is highly skewed as Southeast Asian and Western Pacific regions endure 75% of the global dengue burden. Similar to other regional countries, Malaysia has been rapidly urbanizing, which has supported a hyperendemic dengue state.

The biological pathway by which dengue infection causes a wide range of clinical manifestations, spanning asymptomatic to life-threatening severe complications, is not comprehensively understood. Historically, severe dengue complications have primarily …

An Evaluation Of Booster Training Using Video Modeling With Foster Parents, Anna Katherine Caravello

USF Tampa Graduate Theses and Dissertations

In order for foster parents to be prepared to manage problem behavior and develop a positive relationship with a child in their home, local foster care agencies require these parents to attend parent training classes. Unfortunately, even foster care agencies that offer empirically validated parent training courses are unable to prevent the parents' performance from decreasing over time (Cowart, Iwata, & Poynter, 1984; Forehand & King, 1977; Mueller et al., 2003). However, researchers have created booster training sessions to counteract this issue. Booster training sessions allow participants to attend a brief refresher course on skills they have previously learned. Another …

Faculty, Staff and Student Publications

We conducted a study to establish the psychometric properties of a module of the M. D. Anderson Symptom Inventory (MDASI) developed specifically for patients with lung cancer (MDASI-LC). The MDASI measures 13 common "core" symptoms of cancer and its treatment. The MDASI-LC includes the 13 core MDASI symptom items and three lung cancer-specific items: coughing, constipation, and sore throat. MDASI-LC items were administered to three cohorts of patients with lung cancer undergoing either chemotherapy or chemoradiotherapy. Known-group validity and criterion (concurrent) validity of the MDASI-LC were evaluated using the Eastern Cooperative Oncology Group performance status and the 12-item Short-Form Health …

Distribution And Conservation Status Of Antillean Manatees (Trichechus Manatus Manatus) In Honduras, Daniel González-Socoloske, Cynthia R. Taylor, Olivia R. Rendon Thompson

Faculty Publications

The Antillean manatee, Trichechus manatus manatus, is among the most threatened mammals in Honduras, yet the last published study is from 1980. Since then, the North Coast of Honduras has experienced rapid population growth and land cover change possibly causing habitat loss for manatees. We conducted aerial, boat, and interview surveys between 2005-2007 along the northern and remote eastern coasts of Honduras to assess the current status and distribution of manatees. In addition, we compiled all available data on manatee mortality from museum specimens, unpublished reports, and interviews to determine current threats. We averaged 1.2 manatee sightings per survey hour …

Parental Relationships was measured by the respondents' feelings about how close they felt to their parents on a 4 point Likert scale ranging from no to …

Third Way Architecture: Between Cybernetics And Phenomenology, S Murrani

School of Art, Design and Architecture

This article in its essence aims to challenge and unfold, each at a time, two different fields of methodology – cybernetics and phenomenology – that have direct effects on the product of being and the process of becoming in architectural discourse. Furthermore, this article suggests a third way philosophy for architecture that relates notions of post-phenomenology and technoscience, and considers both to be equally vital to development and speculation within current architectural discourse. First, the history of each of the two fields – cybernetics and phenomenology – will be unveiled with a focus on exploring their impact upon architecture in …

Tailoring Mentoring For New Mathematics And Science Teachers: An Exploratory Study, Christine Ormond

Australian Journal of Teacher Education

This paper explores some aspects of effective professional mentoring practice for early career mathematics and science teachers, and discusses the Early Support Program (ESP), a research project conducted in 2009 and 2010 at a large Australian metropolitan university. It is argued that better outcomes may result from a more strategic “tailoring” of mentoring “type” for different aspects of new teacher induction, especially as school-based mentors often have insufficient time or training to support them. The ESP has been trialling its more “distanced” mentoring model, tracking the issues that a group of new teachers chose to discuss with their mentors, and …

Pre-Service Teachers’ Attendance At Lectures And Tutorials: Why Don’T They Turn Up?, Grace Oakley, Graeme Lock, Fiona Budgen, Brenda Hamlett

Australian Journal of Teacher Education

Research indicates that attendance at lectures and tutorials is associated with university students’ level of success and satisfaction, and pre-service teachers’ relatively low levels of attendance at scheduled classes is of significant concern to many lecturers. However, little research has been undertaken to investigate the factors associated with absenteeism among pre-service teachers. This study investigates rates of absenteeism among different groups of pre-service teachers in a large School of Education in a Western Australian university and considers pre-service teachers’ self-reported reasons for being absent from lectures and tutorials. The results show that levels of attendance and reasons for absence at …

Trait Anxiety And Trait Disgust In Spider Phobia, Laura Vernon, Michiyo Hirai

Psychological Science Faculty Publications

There is evidence for the role of trait anxiety in the specific phobias, and spider phobia in particular. Recently, trait disgust has received attention in relation to specific phobia and researchers and theorists have begun to address its contributions to phobia etiology, maintenance, and treatment processes. There is now strong evidence that a trait or dispositional proneness to experience disgust is related to spider phobia. What is perhaps more important is emerging evidence that both trait anxiety and trait disgust may contribute to spider phobia severity independently of one another. However, the overall picture is far from clear and distinguishing …

Examining The Cause-Related Marketing Relationship Between Children’S Miracle Network And Walmart: Initial Development Of An Ethical Decision Making Framework, Taryn L. Kuntz

Graduate Research Papers

Cause-related marketing relationships have often been identified as win-win-win partnerships for the consumer, nonprofit organization and for-profit corporation. Critics suggest this is not always the case and that in fact, some for-profit organizations participate in such relationships to cover up unethical or illegal behavior. Focusing on Walmart's relationship Children's Miracle Network affiliated children's hospitals, this literature review explores the nature of cause-related marketing relationships and takes a psychological approach to ethical decision making as it relates to philanthropy in order to evaluate whether nonprofit organizations have a concern as a partner in a cause-related marketing relationship. Ethical decision making models …

The Impact Of Attachment Disorder On The Family And Child, Stephanie Durocher

Dissertations and Theses @ UNI

John Bowlby's attachment theory suggests that based on their needs for protection, comfort and nurturance, infants form attachments with their primary caregivers. The initial relationships a person has with others will serve as a blueprint for all future relationships. This connection has a significant influence on every area of a person's life, including cognition, physical and emotional health, future relationships, education and development of values. When an infant's needs are met with inconsistency, abuse or maltreatment, the influence on a child's life and those caring for the child is widespread. This study sought to explore the impact caring for a …

Misconceptions In Middle School Life Science And Strategies Teachers Can Use To Change Them, Jody L. Fairbanks

Graduate Research Papers

Misconceptions and alternative conceptions refer to students' "conceptions that are different from those held by the scientific community" (Sungur, Tekkaya, & Geban, 2001, p. 91). All students have misconceptions due to prior experiences they have had. Students' alternative conceptions are problems for educators because they can block new learning (Sewell, 2002). Therefore, teachers play a crucial role in helping students construct new knowledge upon whatever foundation that already exists. This review of literature examines the findings of research regarding misconceptions, common misconceptions that students have in life science, and how teachers can teach difficult concepts so students are more likely …

Abstract

Background Definitive repair of recurrent ventral hernias using abdominal wall reconstruction techniques is an essential tool in the armentarium for general and plastic surgeons. Ramirez 1 et al describes the “component separation” technique to mobilize the rectus-abdominus internal oblique and external oblique flap to correct the defect. The recurrence rate of incisional hernias increases to 20% after gastric bypass or extensive weight loss.2 The incidence of ventral hernias after failed recurrent hernia repair increases to 40%.3 It has been reported that utilizing the sliding myofascial flap repair technique, the recurrence rate was reduced to 8.5%.4
