The Origins Of An Everyday Behavior: Why Do People Share Meals?, David Lee

Honors Theses

Humans are socially driven creatures that require constant interaction. One way humans have consistently expressed their social nature since prehistory is through sharing meals. Recent studies and literature were examined in order to investigate the roots behind why sharing meals has been the most consistent method of social output. Through careful reading and analysis, reasons behind why people share meals were traced in perspective levels. The biological and molecular aspect explains how humans evolved from prehistoric primates and their similarities associated with food consumption. Genetics and food preferences also play a role by allowing humans to taste food rather than …

Best Interests Of The Child Principle In The Context Of Parent Separation Or Divorce : As Conceptualised By The Community, Nadia Dias

Theses: Doctorates and Masters

Best interests of the child (BIC) is a construct that is central to legal decisions in several areas including parenting matters in the Family Courts, guardianship, child-protection, and adoption. Despite the centrality of the construct, BIC has not been operationalised (Thomson & Molloy, 2001) and there is little agreement about what is considered best for children within social service and legal communities (Banach, 1998). Given that one of the aims of law is to reflect public sentiment (Green, 1996), the current study explored the general public’s conceptualisation of BIC. More specifically, I sought to determine what community members think the …

Raising Teacher Sensitivity To Key Numeracy Competencies In The Early Years, Kelly Norris

Theses: Doctorates and Masters

Mathematical competence is a key capability for success in adult life, and yet many students do not achieve functional levels of numeracy during their school lives. Furthermore, many teachers report that they lack the confidence in teaching mathematics that they have for teaching literacy. Research indicates that it is possible to predict which students are likely to have difficulties in mathematics as early as the Pre-Primary year, and interventions can be provided which are effective in minimising such difficulties. The assumption framing this project is that raising teachers’ understanding of and thus sensitivity to markers of the skills most predictive …

What Remains Is The Book: The Idea Of The Book In And Around Electronic Space, Andy Simionato

Theses: Doctorates and Masters

The purpose of this study is to question the idea of the book in general and how this idea is transforming in electronic space, understood as a space of flows as distinct to a space of places (Castells, 1989, p. 349). In order to question the idea of the book in electronic space we must begin at its ending, or more specifically, at a point in the histories of the book that is widely understood as representing a closing of a parenthesis - that began with the invention of the printing press, up to the end of print—spanning some 500 …

Establishment Of Arbuscular Mycorrhizal Fungi (Amf) On Micropropagated Teak (Tectona Grandis L. F.), Maria Isabel Ramirez Caro

Theses: Doctorates and Masters

Improvement of root production and ability to establish mycorrhizas from different Arbuscular Mycorrhizal Fungi (AMF) inoculum sources on two micropropagated teak (Tectona grandis L. f.) clones was examined at the acclimatisation phase. Teak shoots were maintained on a multiplication medium containing Murashige and Skoog (MS) nutrients and organics, 30 g L-1 sucrose, 0.5 μM benzyl amino purine, 0.5 μM kinetin, 2.5 g L-1 agar, 2.5 g L-1 gelrite and pH 5.8. After 35 days shoots were exposed to a rooting medium (RM) containing ¼ strength MS macronutrients, ½ strength MS iron, full strength MS micronutrients, and 20 g L-1 …

Quantification Of Eccentric Load Using Accelerometer Imbedded In Gps, Chow Chea Yeo

Theses: Doctorates and Masters

Global positioning system (GPS) with a triaxial accelerometer is widely used to monitor movements of athletes in games and training, and “body load” (BL) representing the accumulation of the rate of changes in three planes of movements is obtained to determine the training load of a session. Deceleration, change of directions and stopping require eccentric contractions of leg muscles, potentially causing muscle damage and affecting athletic performance. Thus, it is important to monitor eccentric loading in games and training. A variable known as “eccentric index” (EI) purports to be a better representation of eccentric loading than BL. However, it is …

De Concentv Amisso Qvaerendo: An Investigation Into The Relative Benefits Of Three Different Types Of Ambient Music On The Observed Agitated Behaviour And Quality Of Life Of Dementia Sufferers In Residential Aged Care Facilities, Peter Wilkinson

Theses: Doctorates and Masters

There is an increasing body of research evidence to support the use of music as a therapeutic modality in reducing the agitated behaviour frequently associated with late-stage dementia. Although much of this evidence suggests that music interventions are most effective when they are “individualized”, this type of intervention is often difficult to implement in large, busy, aged care facilities where residents may be located together in communal areas during the day. The challenge therefore is to try and identify a particular musical genre which, when played as “ambient” or “background” music, demonstrates a consistent capacity to reduce agitated behaviour in …

A Preliminary Investigation Of The Potential Effects Of The Invasive Mozambique Tilapia Oreochromis Mossambicus On The Native Fish Assemblages Of Lake Macleod, Western Australia, Hannah Cameron-Caluori

Theses: Doctorates and Masters

As one of the major threats to biodiversity in aquatic systems, invasive species can alter the structure and function of a community, often through habitat and resource competition, and/or direct predation. This study aims to determine if invasive tilapia (Oreochromis mossambicus) is likely to have an effect on the native fish communities of Lake MacLeod, a unique and important inland, saline lake system in north-western Western Australia, through competition for key resources, namely habitat and food sources. Seven study sites were selected within the Northern Ponds of Lake MacLeod, from which fish abundances were assessed in three habitats …

Material Murmurings, Brooke Zeligman

Theses: Doctorates and Masters

This thesis, Material Murmurings, comprising of exegesis and creative practice, focuses on the central research question: “How do we understand the materiality of glass and what happens when said materiality is approached through feminist scholarship?” This question forms the basis for an investigation through creative practice and analysis via an interpretive framework of feminist knowledges of the body. The creative practice embraces glass as the central medium with a series of exhibitions that responded to the interpretive paradigm. It is expected that Material Murmurings will highlight and make evident the value of post-technical approaches in glass art which have only …

A Developmental Approach To Predicting Neuronal Connectivity From Small Biological Datasets: A Gradient-Based Neuron Growth Model., R Borisyuk, Ak Al Azad, D Conte, A Roberts, Sr Soffe

School of Engineering, Computing and Mathematics

Relating structure and function of neuronal circuits is a challenging problem. It requires demonstrating how dynamical patterns of spiking activity lead to functions like cognitive behaviour and identifying the neurons and connections that lead to appropriate activity of a circuit. We apply a "developmental approach" to define the connectome of a simple nervous system, where connections between neurons are not prescribed but appear as a result of neuron growth. A gradient based mathematical model of two-dimensional axon growth from rows of undifferentiated neurons is derived for the different types of neurons in the brainstem and spinal cord of young tadpoles …

Connecting Dots : Interaction Design For Holistic Learning, Michelle Tan

Theses: Doctorates and Masters

Connecting Dots proposes that new media such as interactive websites can be developed using a design framework based on elements of holistic education identified by Miller (1996) as Balance, Inclusion and Connection, so that holistic learning can be achieved. Recognising the negative consequences of the focus on meritocracy, the Singapore government have in recent years advocated for a transformation of the education system to include opportunities for holistic learning. This research contends that holistic learning is a responsibility that has to be shared by both the education system and families. This should be cultivated in a child from an …

Bio-Inspired Surface Engineering For Hydrophobicity, Hua Guo

Theses: Doctorates and Masters

Highly evolved, efficient and sophisticated biological systems can be used as models for scientific innovations. This research explored specific surface structures on plant leaves with respect to their hydrophobicity in the context of the often arid Australian climate. The relationships between leaf surface structures and their hydrophobicity could inform the making of artificial surfaces with specially designed hydrophobicity.

Moderate hydrophobicity and strong surface adhesion were discovered on many study plant leaves. Scanning Electron Microscopy (SEM) revealed that their surface morphologies could be categorized into four groups while their water-repellent mechanisms were considered at an individual species level. Specifically, physical models …

"Wonderfully Ordinary" Words From A Romantic Archive Of Elizabeth Jolley's Writing For Students : Creative Process As A Garland Of Fragments, Andrea Wood

Theses: Doctorates and Masters

This project, including the visual artworks and poetry developed for the exhibition Wonderfully Ordinary, is the outcome of practice-led research into the creative process. Through creative practice—and the development of a personal and fragmentary process of invention—it aims to generate knowledge about creative practice as a form of philosophy in action. Drawing on Paul Carter’s concept of material thinking and historical ideas arising from Western Australian author Elizabeth Jolley’s (1923–2007)creative process and writing, it explores ways in which Friedrich von Schlegel’s (1772–1829) philosophical conception of the Romantic fragment might be revealed as a continuing idea of interest and tool …

The Clinical Utility Of The Halosperm Assay And The Development Of A Simplified Method Of Human Semen Storage For The Testing Of Sperm Dna Fragmentation, Ashleigh Cavell Mcevoy

Theses: Doctorates and Masters

Male infertility is typically diagnosed upon routine semen analysis following the World Health Organisation’s (WHO) semen analysis manual. Recent editions of the manual have essentially changed the diagnosis of a semen sample, prompting debate between experts as to which edition should be followed. Deoxyribonucleic Acid (DNA) integrity analysis is proving to be a useful adjunct to semen analysis as 15% of infertile men have a normal semen analysis but they have an increased DNA fragmentation level (DFL) which has been associated with increased disease incidence in any resultant offspring. However, such tests are not endorsed by the WHO, possibly due …

The Impact Of Implementing A Sudden Infant Death Syndrome Education Package In Jordan, Shereen Hamadneh

Theses: Doctorates and Masters

Background: Sudden Infant Death Syndrome (SIDS) is a problem worldwide. In North Jordan, SIDS rate was high as 1.32 per 1,000 live births and contributed 6% to the infant mortality rate (Bataineh, Shawagfeh, & Twalbeh, 2008). However, SIDS risk factors are preventable and can be reduced by improving knowledge and changing relevant behaviours of parents and healthcare providers (American Academy of Pediatrics, 2013; American SIDS Institute, 2011; Bataineh, Hussein Shawagfeh, & Twalbeh, 2008; Bredemeyer, 2004; Grazel, Phalen, & Polomano, 2010b; Moon, Oden, & Grady, 2004; NICHD, 2010). Still educating Jordanians about SIDS has not been a national health policy priority. …

The Antibacterial Effects Of Silver, Titanium Dioxide And Silica Dioxide Nanoparticles Compared To The Dental Disinfectant Chlorhexidine On Streptococcus Mutans Using A Suite Of Bioassays., Alexandros Besinis, Peralta T De, Richard D. Handy

School of Engineering, Computing and Mathematics

Metal-containing nanomaterials have the potential to be used in dentistry for infection control, but little is known about their antibacterial properties. This study investigated the toxicity of silver (Ag), titanium dioxide and silica nanoparticles (NPs) against the oral pathogenic species of Streptococcus mutans, compared to the routine disinfectant, chlorhexidine. The bacteria were assessed using the minimum inhibitory concentration assay for growth, fluorescent staining for live/dead cells, and measurements of lactate. All the assays showed that Ag NPs had the strongest antibacterial activity of the NPs tested, with bacterial growth also being 25-fold lower than that in chlorhexidine. The survival rate …

Effects Of Vibrotactile Display Position And Shape On Extrapersonal Localization, Adam D. Sitz

Psychology Theses & Dissertations

Vibrotactile displays are capable of conveying extrapersonal spatial information to users navigating or operating within a three-dimensional environment (e.g., aircraft pilots). Although vibrotactile displays can be applied to many parts of the body, recent applications have focused on torso-based displays that egocentrically reference distal targets. However, these displays may be poorly suited to convey elevation because of the generally cylindrical shape of the human torso. The purpose of the present study was to evaluate the relative effectiveness of handheld vibrotactile displays configured either in a cylindrical or spherical-shape as compared to a torso-based display. Due to its shape, the spherical …

Effect Of Farmer's Knowledge And Attitudes On Management Of The Tomato Spotted Wilt Virus In Sironko District, Rita Nabuzale

All Master’s Theses

Over 80 percent of the population in Uganda live in rural areas and is mainly engaged in subsistence agriculture for their livelihood. Crop farming especially tomato growing is an activity that communities rely on for their livelihoods as well as a source of income for many households in Uganda. Tomatoes contribute to the household income, food and nutritional security yet they are affected by pests and diseases due to poor agronomic practices, lack of improved varieties for high yields and resistance to diseases. Among tomato diseases, tospoviruses have been ranked as the third most important constraint and are spread by …

Comparative And Functional Analysis Of Tsetse Fly Aquaporins, Erick Onyango Aroko

All Master’s Theses

Tsetse flies (Glossina sp) are the vector of African trypanosomes, the causative agents of sleeping sickness in man and Nagana in cattle. The insect is strictly hematophagous, taking in significantly high quantities of water during bloodmeals that present a considerable osmotic challenge. This necessitates machinery for eliminating excess water. One potential candidate is a group of membrane channel proteins called aquaporins (AQPs) that are responsible for the movement of water across cell membranes. In other insect species, aquaporins have been shown to facilitate physiological processes including desiccation and freeze tolerance. Gmmdripa aquaporin has been shown to play an important role …

Health Seeking Behaviour In Malaria Treatment By The Fishing Community Of Rusinga Island, Western Kenya, Jacqueline E. Oduke

All Master’s Theses

Literature on health and diseases indicate that people perceive diseases variously. People develop their own views and beliefs about the causes, symptoms, modes of transmission and therapy choices, which then influence their health seeking behaviour. The main objective of this study was to explore health seeking behaviour in relation to malaria among the fishermen on Rusinga Island on Lake Victoria Kenya. This study which focused on the fishermen on Rusinga Island on Lake Victoria Kenya sought to establish the behavioural practices that are thought to predispose fishermen to malaria, the social cultural factors influencing their choices of therapy and the …

Isolation And Characterization Of Cellulolytic Bacteria From Soils Excavated From Geothermal Wells Along The Kenyan Rift Valley, Irene Kiio Kateve

All Master’s Theses

Cellulolytic microorganisms such as fungi and bacteria are responsible for much of the cellulose degradation in soils. Despite this vast number of cellulase producers, there is a deficiency of microorganisms that can produce significant amount of the three cellulase enzyme specifities i.e. endoglucanases, exoglucanases and cellobiases to efficiently degrade cellulose to fermentable products. Little emphasis has been given to cellulase production from bacteria despite their extremely high natural diversity, which endows them with the capability to produce stable enzymes. Soil samples were collected from Hell's gate and from a geothermal well in Eburru hill at depths of 155 Metres, 156 …

Law And Neuroscience: Recommendations Submitted To The President's Bioethics Commission, Owen D. Jones, Richard J. Bonnie, Bj Casey, Andre Davis, David L. Faigman, Morris B. Hoffman, Read Montague, Stephen J. Morse, Marcus E. Raichle, Jennifer A. Richeson, Elizabeth S. Scott, Laurence Steinberg, Kim Taylor-Thompson, Anthony Wagner, Gideon Yaffe

Faculty Scholarship

It has become increasingly clear that implications for criminal justice – both negative and positive – emerge from the rapid, important, and challenging developments in cognitive neuroscience, the study of how the brain thinks. Two examples will illustrate.

First, lawyers are ever more frequently bringing neuroscientific evidence into the courtroom, often in the forms of testimony about, and graphic images of, human brains. This trend has produced many new challenges for judges as they attempt to provide fair rulings on the admissibility of such technical evidence, consider its proper interpretation, and assess whether the probative value of such testimony may …

Intellectual Property Geographies, Peter K. Yu

Faculty Scholarship

Written for a special issue on intellectual property and geography, this article outlines three sets of mismatches that demonstrate the vitality, utility and richness of analyzing intellectual property developments through a geographical lens. The article begins by examining economic geography, focusing on the tensions and conflicts between territorial borders and sub-national innovation (including those relating to obligations under the WTO TRIPS Agreement). This article then examines the oft-found mismatch between political geography and cultural geography. Illustrating this mismatch is the challenge of protecting traditional knowledge and traditional cultural expressions. The article concludes by exploring the growing mismatch between legal geography …

Assessing The Fishery And Ecology Of Sharks In The United Arab Emirates, Rima W. Jabado

Dissertations

Large scale shark population declines have been documented worldwide due to overexploitation and the lack of adequate management frameworks to conserve shark stocks. This study aimed at gaining an understanding of the national shark fishery and the trade in shark products from the United Arab Emirates (UAE). Data were collected from June 2010 to October 2012 through interviews with local fishermen, market and landing site surveys, fishery independent surveys, and stomach content analysis. Interviews with local fishermen (n=126) provided information on the fishery characteristics and established that sharks were increasingly targeted due to their high value in the global fin …
