Perceptions Of Security And Attitudes Towards Cultural Diversity And Immigration Amongst Uk Migrants In Western Australia, Nikki Isaacson

Theses : Honours

Psychological research conducted within the field of ethnic relations has revealed a strong relationship between an individual's perception of threat to their ethnocultural group and their attitudes towards the entrance and presence of other ethnocultural groups within a society. The relationship is such that the greater threat that an individual perceives, the more likely they are to hold negative attitudes. This paper provides a review of research that has investigated this relationship; revealing that although a distinct negative correlation exists between perceived threat and intercultural attitudes, a number of factors influence the relationship. Factors discussed throughout this review include the …

An Investigation Into The Effectiveness Of Paired Reading With The Incorporation Of Additional Error Corrective Procedures, Kathryn Schneider

Theses : Honours

The aim of this literature review was to examine the effectiveness of the Paired Reading (PR) intervention, a one-to-one instruction approach to improving children's fluency, accuracy, and comprehension. The effectiveness of PR in promoting a positive attitude towards reading and in increasing children's sense of self-efficacy in reading was also investigated, focusing principally on children whose level of reading was below what was expected for their chronological age. It addressed the question of how well the intervention can be implemented by parents and explored the strategies used in PR to elucidate what aspects of the intervention may contribute to its …

Theoretical explanations of ethnocentrism and intergroup processes are provided, and ethnocentrism is discussed in relation to several precipitators and moderators of ethnocentric attitudes to immigration and diversity, including authoritarianism, social dominance, security, ethnic hierarchies, cultural distance, and social conditions. It is recommended that future research focuses on the …

Externalising Behaviour Problems And The Influence Of Classroom Environments In The Early School Years ; Student-Teacher Relationships And Teacher Discipline: Their Relation To The Externalising Behaviours Of Kindergarten To Year 1 Students, Emma Spencer

Theses : Honours

Some of the most influential people in a child's life are the teachers who aid them in their transition into the education system and the complex social environment that it brings (Blancher & Eisenhower, 2006). Children who display externalising behaviours early in childhood often experience greater difficulties than other children when entering school and throughout their education experience (Hinshaw, Lahey & Hart, 1993; Liu, 2004). The student-teacher relationship established within the classroom and the disciplinary measures utilized by the teachers can have a profound impact on the child's development both academically and socially (Galen & Underwood, 1997; Hamre & Pianta, …

Cinematography And Choreography: "It Takes Two To Tango", Laura Boynes

Theses : Honours

As a practicing dancer and choreographer with a developing interest in film, the lifelong struggle (where many have gone before) to capture and accurately depict choreography on screen, intrigues me.

Who should dance the camera or the choreography? These are questions that have been pondered by choreographers and theorists for centuries, with pioneers such as Busby Berkeley and Maya Deren each finding their own answers to success.

This thesis discusses the creation and production of dance film, and the importance of movement in front of and behind the camera lens. I believe experimentation and research are the most effective methods …

A Methodology For Thorough Text Preparation Of German Lieder, Emma Louise Blake

Theses : Honours

The impetus behind this study is the suspicion that singers beginning their training are either unaware of the vast amount of preparation that needs to occur when performing any work or they are aware but have no idea where to start. The understanding of text and an emotional connection with its meaning are vital to a successful Lied performance. This dissertation aims to create a method of preparing the text (of a Lied) that encourages detailed observation and creative thought, and which enables a musician with limited understanding of the German language to comfortably acquaint themselves with the repertoire. This …

Changes In A Chinese Interior Design Firm Due To The Development And Use Of A Blog-Based Reflective Practitioner Knowledge Management System Inspired By Chinese Philosophy: An Autoethnographic Case Study, Chun Kwan Law

Theses: Doctorates and Masters

Dao (Way)

The Way that can be experienced is not true;

The world that can be constructed is not true.

The Way manifests all that happens and may happen;

The world represents all that exists and may exist.

To experience without intention is to sense the world:

To experience with intention is to anticipate the world.

These two experiences are indistinguishable;

Their construction differs but their effect is the same.

Beyond the gate of experience flows the Way'.

Which is ever greater and more subtle than/he world.

Lao-Tzu, TaoDeChing, tr. Peter A. Merel

Acadian Biospeleology: Composition And Ecology Of Cave Fauna Of Nova Scotia And Southern New Brunswick, Canada, Max Moseley

International Journal of Speleology

The vertebrate and invertebrate fauna, environment and habitats of caves and disused mines in Nova Scotia and southern New Brunswick are provisionally catalogued and described, based on field collections made over many years. The area was glaciated and the subterranean fauna consists of non-troglobites all of which have arrived and colonised the caves during or following final recession of the Pleistocene glaciers. The statistical composition of the fauna at the higher taxonomic level is similar to that in Ontario, but is less species rich and there are some notable ecological and other differences. Porcupine dung accumulations are an important habitat …

Sails: A New Gypsum Speleothem From Naica, Chihuahua, Mexico, Tullio Bernabei, Paolo Forti, Roberto Villasuso

International Journal of Speleology

The caves of Naica (Chihuahua, Mexico) are perhaps the most famous mine caves of the world due to the presence of gigantic gypsum crystals. Nevertheless, very little research has been carried out on this karst area until now. A multidisciplinary investigation started in 2006 with the aim not only to define the genesis and the age of the Naica gypsum crystals, but also on other scientific aspects of these caves. This paper describes a completely new type of gypsum speleothem: the “sails”, observed only inside the Cueva de las Velas, one of the caves of the Naica system. This speleothem …

Bomb-Spike Dating Of A Mummified Baboon In Ludwig Cave, Namibia, Greg Hodgins, George A. Brook, Eugene Marais

International Journal of Speleology

In 1982 a mummified adult female baboon was discovered on a ledge in Ludwig Cave in Namibia. A toe bone was removed for dating in July 1995. AMS radiocarbon dating of bone collagen, tendon, and skin indicates a post-modern age. Application of the atomic bomb-spike calibration curve suggests death in late 1977 and an age at death of around 19 years. Baboons roost in the cave and the mummified female, along with a mummified juvenile male discovered in 2002 and three rotting corpses discovered in 1995, were probably chased by other baboons or by leopards down a ca. 6 m …

Petrographic And Geochemical Study On Cave Pearls From Kanaan Cave (Lebanon), Fadi H. Nader

International Journal of Speleology

The Kanaan cave is situated at the coastal zone, north of Beirut City (capital of Lebanon). The cave is located within the upper part of the Jurassic Kesrouane Formation (Liassic to Oxfordian) which consists mainly of micritic limestone. Twenty seven cave pearls were subjected to petrographic (conventional and scanning electron microscopy) and geochemical analyses (major/trace elements and stable isotopes). The cave pearls were found in an agitated splash-pool with low mud content. They are believed to have formed through chemical precipitation of calcite in water over-saturated with calcium. The nucleus and micritic laminae show δ¹⁸O_V-PDB values of …

Impacts Of Acid Mine Drainage On Carbon Cycling In Receiving Streams, Ernest W. Fonyuy

Doctoral Dissertations

"Field and laboratory investigations of acid mine drainage (AMD) contaminated and uncontaminated waters were conducted in order to determine and model processes and reaction mechanisms that control dissolved inorganic carbon (DIC) transformation and shifts in isotope ratio of DIC (Δ¹³C_DIC). The results show that AMD caused variable pH changes, overall decreases in Fe²⁺, alkalinity, and DIC, and increases in (Δ¹³C_DIC) in receiving streams. AMD caused more than 50 to > 98% seasonal DIC loss in stream water through CO₂ degassing. High DIC losses corresponded to high Fe²⁺ and lower or no HCO₃⁻ in the water samples, because …

A Computational Theory For The Generation Of Solutions During Early Conceptual Design, Cari R. Bryant

Doctoral Dissertations

"Advancement in technology is usually made by building on previous experiences and learning from past successes and failures. However, knowledge transfer in the broad field of product design is often difficult to accomplish. Research has shown that successful component configurations, observed from existing products, can be dissected and stored for reuse; but few computational tools exist to assist designers during the conceptual phase of design. Many well-known manual methods (e.g. brainstorming, intrinsic and extrinsic searches, and morphological analysis) rely heavily on individual bias and experience and are often time intensive, laborious tasks that may not catch solutions that are functionally …

Detection Of Flash In Dermoscopy Skin Lesion Images, Radhika Nagane

Masters Theses

"Dermoscopy images of skin lesions are often acquired by covering the skin with mineral oil, alcohol, another liquid or a gel and illuminating the area at a low angle of incidence from all directions before taking the photograph. Deeper pigment patterns are more visible in this type of image than in a clinical image because the liquid immersion and structured light effectively make the upper layers of the skin more transparent. Flash regions are the small, high reflectance areas in the image where direct reflections of the illumination source(s) cause undesirable bright spots in the image. These flash regions may …

Factors Associated With Atypical Moles In New Hampshire, Usa, L Titus-Ernstoff, J Ding, A. E. Perry, S. K. Spencer, B. F. Cole, M. S. Ernstoff

Dartmouth Scholarship

Only a few studies, conducted in Sweden, assessed factors associated with the presence of atypical moles in the general population. We conducted a population-based, case-control study in New Hampshire, USA, to identify factors associated with atypical moles. In our study, atypical moles affected 14% of the study population. The adjusted odds ratio (OR) was 0.34 (95% confidence interval (CI)=0.14-0.80) for those with the highest adulthood recreational sun exposure, relative to the lowest. The OR for any freckles, compared to none, was 2.24 (95% CI=1.18-4.25). We found a linear relationship between the number of benign moles and the presence of atypical …

The Proteoglycan Perlecan Regulates Long Bone Growth Through Interactions With Developmental Proteins In The Growth Plate, Simone Marsha-Lee Smith

USF Tampa Graduate Theses and Dissertations

Perlecan is the major heparan sulfate proteoglycan (HSPG) in growth plate cartilage and is critical for growth plate chondrocyte proliferation and proper skeletal development. Its core protein and attached chondroitin sulfate (CS) and heparan sulfate (HS) chains mediate interactions with many diverse proteins. Fibroblast growth factor (FGF)-2 and FGF-18 are other regulators of chondrocyte proliferation in the growth plate. Additionally, FGF-18 controls the hypertrophy and cartilage vascularization necessary for endochondral ossification. The research presented in this dissertation aimed to identify known and novel perlecan-binding proteins that are endogenous to the growth plate and to characterize their interactions with perlecan. FGF-2 …

The Effect Of Thin-Slicing On Structured Interview Decisions, Gregory F. Schmidt

USF Tampa Graduate Theses and Dissertations

This study examined whether hiring recommendations based on thin slices of a structured interview were associated with recommendations based on the interview in its entirety. After viewing 12 seconds of silent interviewee behavior, participants made hiring recommendations that were significantly correlated with those produced by individuals viewing a still-frame of the interview and the entire interview. In an effort to determine what sources of information participants were using to arrive at their recommendations, nonverbal behaviors were examined in detail. Applicants who appeared attentive, not anxious, competent, confident, dominant, optimistic, and professional were more likely to receive positive hiring recommendations than …

Pricing Models And Analysis Of Corporate Coupon-Bonds And Credit Default Swaptions, Michiru Shibata

USF Tampa Graduate Theses and Dissertations

In this work, pricing models of corporate coupon-bonds and credit default swaptions are derivedand analyzed. Corporate coupon-bonds are priced incorporating both intensity models and structural models, and also jumps introduced by seasonal effects. In deriving the models, we form portfolios to hedge the risk incurred by the instruments, then derive PDE equations using the arbitrage principle and the Ito Lemma for jump processes. The mathematical models are the parabolic-type PDE equations with terminal conditions and boundary conditions. These PDE problems are analyzed and solved by various transformations and incorporation with probabilistic properties. Either a unique solution in the exponential form …

Src Kinase Inhibitors For The Treatment Of Sarcomas: Cellular And Molecular Mechanisms Of Action, Audrey Cathryn Shor

USF Tampa Graduate Theses and Dissertations

Sarcomas are rare mesenchymally-derived tumors with limited treatment options. Tyrosine kinases may serve as potential targets for sarcoma therapy because many are mutated or overexpressed in sarcomas and cell lines. One potential molecular target for sarcoma treatment is the Src tyrosine kinase. Three independently synthesized Src kinase inhibitors were evaluated in human sarcoma cell lines. Of the three, dasatinib, provided promising results as a potential sarcoma therapy. Until this study, dasatinib activity had not been characterized in sarcoma cells. Based on our previous findings of Src activation in human sarcomas, we evaluated the effects of dasatinib in twelve sarcoma cell …
