Experimental Investigation Of Active Control Of Bluff Body Vortex Shedding, Ilteris Koc Jan 2008

Experimental Investigation Of Active Control Of Bluff Body Vortex Shedding, Ilteris Koc

Mechanical & Aerospace Engineering Theses & Dissertations

Mean and fluctuating forces acting on a body are strongly related to vortex shedding generated behind it. Therefore, it is possible to obtain substantial reductions of at least the unsteady forces if vortex shedding is controlled or its regularity is reduced. While conventional active flow control methods are mainly concerned with direct interaction with, and alteration of, the mean flow about a body, modern techniques involve altering existing flow instabilities using relatively small inputs to obtain large-scale changes of mean flows. Aerodynamic flow control may be intended to delay or suppress boundary layer separation through creation of a boundary layer …


Mother-Daughter Communication And Media Influence On Self-Esteem And Body Image, Tori Austin Jan 2008

Mother-Daughter Communication And Media Influence On Self-Esteem And Body Image, Tori Austin

Dissertations and Theses @ UNI

Societal norms based on media venues influence the perception young females have of themselves; however, some literature indicates the mother daughter relationship can help minimize the possible negative effects. Young women are more susceptible to desire distorted media images of glamorous and thin women. As they make social comparisons with mediated images of womanhood, they may become disappointed in their own body image and possess lower self-esteem. The previous research has gaps when discussing mother daughter relationships, media's influence, and the impact on adolescent girls' self-esteem and body image. To determine predictors to young women's self-esteem and body image, 119 …


Rapid Prototyping For Virtual Environments, Emre Baydogan Jan 2008

Rapid Prototyping For Virtual Environments, Emre Baydogan

Electrical & Computer Engineering Theses & Dissertations

Development of Virtual Environment (VE) applications is challenging where application developers are required to have expertise in the target VE technologies along with the problem domain expertise. New VE technologies impose a significant learning curve to even the most experienced VE developer. The proposed solution relies on synthesis to automate the migration of a VE application to a new unfamiliar VE platform/technology. To solve the problem, the Common Scene Definition Framework (CSDF) is developed, that serves as a superset/model representation of the target virtual world. Input modules are developed to populate the framework with the capabilities of the virtual world …

Low Reproductive Success Of Mallards In A Grassland-Dominated Landscape In The Sandhills Of Nebraska, Larkin A. Powell, Johann Walker, Zach Cunningham, Mark P. Vrtiska, Scott Stephens Jan 2008

Low Reproductive Success Of Mallards In A Grassland-Dominated Landscape In The Sandhills Of Nebraska, Larkin A. Powell, Johann Walker, Zach Cunningham, Mark P. Vrtiska, Scott Stephens

School of Natural Resources: Faculty Publications

The Sandhills of Nebraska comprise approximately 5,000,000 ha of native grassland interspersed with numerous groundwater-fed wetlands. A substantial population of the mallard (Anas platyrhynchos) nests in this region. Previous investigations of nest survival probability of ducks in the Sandhills have estimated surprisingly low rates of nest survival for a grassland-dominated landscape. These investigations were conducted on public lands and most nest searching took place near wetlands where activity of nest predators might be highest. We predicted that mallards would nest at varying distances from wetlands and that survival probability of a representative sample of duck nests would increase with distance …


Creating Preservation-Ready Web Resources, Joan A. Smith, Michael L. Nelson Jan 2008

Creating Preservation-Ready Web Resources, Joan A. Smith, Michael L. Nelson

Computer Science Faculty Publications

There are innumerable departmental, community, and personal web sites worthy of long-term preservation but proportionally fewer archivists available to properly prepare and process such sites. We propose a simple model for such everyday web sites which takes advantage of the web server itself to help prepare the site's resources for preservation. This is accomplished by having metadata utilities analyze the resource at the time of dissemination. The web server responds to the archiving repository crawler by sending both the resource and the just-in-time generated metadata as a straight-forward XML-formatted response. We call this complex object (resource + metadata) a CRATE. …


Emergent Behavior In Massively-Deployed Sensor Networks, Ekaterina Shurkova, Ruzana Ishak, Stephan Olariu, Shaharuddin Salleh Jan 2008

Emergent Behavior In Massively-Deployed Sensor Networks, Ekaterina Shurkova, Ruzana Ishak, Stephan Olariu, Shaharuddin Salleh

Computer Science Faculty Publications

The phenomenal advances in MEMS and nanotechnology make it feasible to build small devices, referred to as sensors that are able to sense, compute and communicate over small distances. The massive deployment of these small devices raises the fascinating question of whether or not the sensors, as a collectivity, will display emergent behavior, just as living organisms do. In this work we report on a recent effort intended to observe emerging behavior of large groups of sensor nodes, like living cells demonstrate. Imagine a massive deployment of sensors that can be in two states "red" and "blue". At deployment time …


Efficient Corona Training Protocols For Sensor Networks, Alan A. Bertossi, Stephan Olariu, Cristina M. Pinotti Jan 2008

Efficient Corona Training Protocols For Sensor Networks, Alan A. Bertossi, Stephan Olariu, Cristina M. Pinotti

Computer Science Faculty Publications

Phenomenal advances in nano-technology and packaging have made it possible to develop miniaturized low-power devices that integrate sensing, special-purpose computing, and wireless communications capabilities. It is expected that these small devices, referred to as sensors, will be mass-produced and deployed, making their production cost negligible. Due to their small form factor and modest non-renewable energy budget, individual sensors are not expected to be GPS-enabled. Moreover, in most applications, exact geographic location is not necessary, and all that the individual sensors need is a coarse-grain location awareness. The task of acquiring such a coarse-grain location awareness is referred to as training. …

How does each association perceive the development planning processes?, and; (iii) How does organisational culture influence planning processes? To …


A Study Of Compliance In Aged Care Facilities With Regards To Australian Standards 1851:2006 Maintenance Of Fire Protection Systems And Equipment Section 17, Robert Doleman Jan 2008

A Study Of Compliance In Aged Care Facilities With Regards To Australian Standards 1851:2006 Maintenance Of Fire Protection Systems And Equipment Section 17, Robert Doleman

Theses : Honours

The management of risk within a nursing home environment is widely viewed as an undertaking perfom1ed by the owners or managers of nursing homes. The residents of these homes are reliant upon the owners and managers to keep them safe, due in part to a traditional belief that they are the experts and have a greater understanding of risk. To establish risk it is first a requirement to have an understanding of levels of risk and risk management techniques. Risk appreciation is often influenced by heuristic representativeness, as well as social and cultural influences. The higher level of risk within …


Exploration Of The Authentic Apology Theory: An Examination Of The Reasons Why People Reject An Apology, Stephenie Bruce Jan 2008

Exploration Of The Authentic Apology Theory: An Examination Of The Reasons Why People Reject An Apology, Stephenie Bruce

Theses : Honours

The aim of the present literature review was to explore the reasons why people reject an apology. A search of the literature revealed virtually no research focusing specifically on apology rejection, therefore, it was proposed that this lack of research may be due to the general reluctance of apology recipients to respond with rejection (Bennett & Dewberry, 1994; Bennett & Earwaker, 1994; Risen & Gilovich, 2007). Given the dearth of literature on apology rejection, it was imperative that the review also examined the literature on apology in general, in addition to literature on apology and forgiveness, in order to discover …


Is Enough Really Enough? : Evaluation Of An Alcohol Awareness Campaign At Ecu Joondalup, Marissa Macdonald Jan 2008

Is Enough Really Enough? : Evaluation Of An Alcohol Awareness Campaign At Ecu Joondalup, Marissa Macdonald

Theses : Honours

Australian young adults aged 17-25 years old attending university are more likely to drink at levels which put themselves at risk of both short and long term alcohol-related harm. University settings are an appropriate place to target university students with alcohol education or awareness-raising campaigns. Australian research on this topic is relatively limited. This mixed methods study involved two phases. The first phase quantitatively evaluated the impact of the 'Enough is Enough' campaign, implemented by the North Metropolitan Community Drug Service Team at ECU Joondalup, on students' awareness of the consequences of excessive alcohol use and perceived acceptability of drunkenness. …


Modulation Of Corticomotor Excitability During Passive And Active Wrist Flexion And Extension, Lilian Min Yen Chye Jan 2008

Modulation Of Corticomotor Excitability During Passive And Active Wrist Flexion And Extension, Lilian Min Yen Chye

Theses : Honours

Various mechanisms may alter corticomotor excitability to agonist and antagonist muscles during passive and active limb movement depending on parameters of movement and their functional role. A better understanding of these relationships is important for understanding basic motor control mechanisms, and may be relevant to motor rehabilitation programs after brain injury. The purpose of the present study was to compare changes in corticomotor excitability to wrist flexor and extensor muscles during different phases of movement (flexion/extension), and at rest and during actively or passively-mediated length changes. Motor evoked potentials (MEP) of the flexor carpi radialis (FCR) and extensor carpi radialis …


Cognitive Theories Of Autism Spectrum Disorders: How Do They Impact Children's Ability To Learn In Education Settings? ; Coming Home: Exploring The Experiences Of Mothers Home Educating Their Children With Autism Spectrum Disorder, Theresa Kidd Jan 2008

Cognitive Theories Of Autism Spectrum Disorders: How Do They Impact Children's Ability To Learn In Education Settings? ; Coming Home: Exploring The Experiences Of Mothers Home Educating Their Children With Autism Spectrum Disorder, Theresa Kidd

Theses : Honours

Despite the increasing number of children with autism spectrum disorder (ASD) attending mainstream school, the process of facilitating their learning and participation remains a complex and poorly understood area of education (Simpson, de Boer, & Smith-Myles, 2003). Three key cognitive theories (theory of mind, theory of weak central coherence and theory of executive function) have been posited to provide the most complete understanding of the disorder (Baron-Cohen, 1989). Presently however, the developmental effects of these cognitive theories have been largely overlooked (Happe, 1994). Through examining how these models may affect cognitive processing in children with ASD, the learning and educational …


A Parental Perspective: The Role Of Companion Animals For Children During Separation And Divorce, Jessica Michel Jan 2008

A Parental Perspective: The Role Of Companion Animals For Children During Separation And Divorce, Jessica Michel

Theses : Honours

Children grow up in interdependent family systems, where transitions affect all members. A prevalent transition in Australian families is divorce. When divorce occurs children are exposed to significant risk factors that have the potential of affecting many developmental outcomes. However, certain protective factors may reduce the impact of life stressors and a pivotal protective factor is social support. Companion animals have been recognised as beneficial to adults and children alike for many years, however, recent research has highlighted the fact that pets may also serve as sources of social support. The current paper will review relevant literature to determine the …


Understanding Seychelles Students' Social, Academic And Cultural Experiences During Transition To University, Sophia A. Harryba Jan 2008

Understanding Seychelles Students' Social, Academic And Cultural Experiences During Transition To University, Sophia A. Harryba

Theses : Honours

University transition is a form of change from the familiar to unfamiliar (Hellsten, 2002). According to a literature review, international students (IS) go through both positive and negative experiences due to cross- cultural learning (Grey, 2002). Findings from previous research can be broadly categorised into academic and/or socio-cultural difficulties. Academic issues included getting used to a different learning and teaching environment, a heavier study load coupled with language barriers and academic procedures (Mcinnis, 2001). Socio-cultural issues included culture shock (Townsend & Wan, 2007), language difficulties (Cannon, 2002), discrimination (Poyrazli & Lopez, 2007) and financial issues (Forbes- Mewett et al., 2007). …


The Effects Of An Offender's Ethnicity As Well As The Type Of Crime Committed, On Public Perceptions Regarding Seriousness, And The Sentencing Principles Seen As Most Appropriate, Andrea Kysely Jan 2008

The Effects Of An Offender's Ethnicity As Well As The Type Of Crime Committed, On Public Perceptions Regarding Seriousness, And The Sentencing Principles Seen As Most Appropriate, Andrea Kysely

Theses : Honours

Public opinion has been evidenced as exerting significant influence over the development of, and alteration to, policies dealing with offenders (Roberts, 1992). Research suggests that an offender's ethnicity, as well as the seriousness of a crime, have a significant effect on public opinion regarding the appropriateness of an imposed sentence, and the goals of sentencing seen as most important (Herzog & Rattner, 2003). However whilst research in the United States and Europe has continued to expand, there is a significant lack of research directly related to the Australian context. The significant over-representation of Indigenous Australians in Australian prisons, potentially reflects …

Dancing On The Edge Of Silence : Steps Towards Articulating The Experience Of Childhood Rape, Brenda Joy Downing Jan 2008

Dancing On The Edge Of Silence : Steps Towards Articulating The Experience Of Childhood Rape, Brenda Joy Downing

Theses : Honours

The experience and aftermath of male sexual violence is a lived reality for many girls and women. This qualitative study explores the subjective experience of childhood rape and its long-term impact focusing in particular on the implications of the silencing that continues to surround what is a deeply-felt and traumatic experience with profound life-altering consequences. The study thematically and theoretically reads the subjective experience of childhood rape within current feminist understandings of rape as a crime of violence and form of social control through the use of evocative autoethnographic writing and an exegesis.


Factors That Influence Perception Of Seriousness Of Crime : The Application Of Race, Type Of Offence And Dispositional Empathy To An Australian Context, Giselle Larkins Jan 2008

Factors That Influence Perception Of Seriousness Of Crime : The Application Of Race, Type Of Offence And Dispositional Empathy To An Australian Context, Giselle Larkins

Theses : Honours

The perception of seriousness of crime may be altered by numerous extra-legal factors within the criminal justice system. It is of significant importance to understand the ways in which various factors contribute to the differential treatment of defendants. Prejudicial attitudes towards Indigenous people pervade all areas of Australian society, including the criminal justice system (Paradies, 2005). For instance, although Indigenous people form approximately 2.4% of the general Australian population, they contribute to 24% of the total prison population (ABS, 2007; Paradies). Despite this, few studies have actively sought to better understand the factors that may contribute to varied perceptions of …


Exploring Young Adult Conflict Management Skill Development, Pauline Marcoux Jan 2008

Exploring Young Adult Conflict Management Skill Development, Pauline Marcoux

Theses : Honours

This paper explores conflict management skill development of young adults. Although conflict management is a life-span issue, conflict management skills are of particular importance to young adults as they develop their identity and explore romantic relationships. The study of conflict management skills is complex and is underpinned by different theoretical approaches. These complexities and theories are presented. Findings from childhood to young adulthood are reviewed and summarised. Marital conflict, parent-child interactions, family-of-origin characteristics and attachment orientation are all factors that influence the development of conflict management skills. The family-of-origin characteristics seem to provide the most meaningful results in relation to …


An Exploration Of The Perceptions Domestic Groundwater Users Hold In Relation To Perth's Groundwater Resources, Beverley Drayton-Witty Jan 2008

An Exploration Of The Perceptions Domestic Groundwater Users Hold In Relation To Perth's Groundwater Resources, Beverley Drayton-Witty

Theses : Honours

Australia's water resources over the next few decades, and most likely beyond, will be under increasing pressures as populations enlarge and as the amount of water per person becomes more limited from a decline in rainfall across much of the continent. Perth is considered lucky among most Australian cities when it comes to water resources, in that we have an extensive groundwater network that is readily accessible both for both private (wells and bores) and public (scheme water) supplies. However, this resource has also seen substantial declines over the last few decades resulting from declining rainfall and increased use. Although …


Knowledge And Perceptions About Hepatitis C Among Police Undertaking Training At The Western Australia Police Academy, Cerissa Papanastasiou Jan 2008

Knowledge And Perceptions About Hepatitis C Among Police Undertaking Training At The Western Australia Police Academy, Cerissa Papanastasiou

Theses : Honours

Hepatitis C (HCV) is a significant health issue in Australia with approximately 90% of new cases attributed to injecting drug use (IDU). With no vaccination for this infection it is important that preventive methods are utilised to reduce the likelihood of it being transmitted from the IDU community into the wider community. Research has suggested that people's beliefs, which are influenced by the knowledge they have, play an important role in influencing the action people take in protecting and promoting their health. While there are numerous studies which have measured the HCV-related knowledge and perceptions of other professions in the …


Factor Structure Of The Life Orientation Test And Life Orientation Test- Revised: The Influence Of Item Framing, Jamie Moore Jan 2008

Factor Structure Of The Life Orientation Test And Life Orientation Test- Revised: The Influence Of Item Framing, Jamie Moore

Theses : Honours

Historically psychological scales have used a mix of positively keyed and negatively keyed items (balanced scales) to control for the effects of response sets. While it has been established that the use of balanced scales does effectively control for response sets such as acquiescence, issues relating to the psychometric properties of these scales emerge. The following review investigated issues surrounding the reliability, validity and factor structure of balanced scales by considering whether these issues were caused by positively and negatively keyed items measuring different aspects of a construct or whether they emerged simply due to measurement error. Both these positions …
