First Detection, Characterization, And Application Of Amorphous Calcium Phosphate In Dentistry, Jie Zhao, Yu Liu, Wei-Bin Sun, Xuebin Yang

Journal of Dental Sciences

Abstract Background/purpose This literature review provides an overview of the first detection, structure, chemical composition, morphology characterization, phase transformation, and clinical application of amorphous calcium phosphate (ACP) to dentistry. Materials and methods ACP is the essential mineral phase formed in mineralized tissue and the first product to be used as artificial hydroxyapatite. ACP is unique among the calcium phosphates in that it lacks the long-range, periodic atomic scale order of crystalline calcium phosphates. Its X-ray diffraction patterns are broad and diffuse with a maxima at 25° 2θ, and no other different features compared with well-crystallized hydroxyapatite. Under electron microscopy, its …

Knowledge Of The Uv Index Within Western Australia, David Mercovich

Theses : Honours

Australia has the highest rate of skin cancer in the world and despite the dedicated efforts of preventative campaigns since 1981; this number has increased over the past ten years (Carter & Donovan, 2007). With most skin cancer being attributed to Ultra violet radiation there is a pressing need for proper education, health promotion and preventative means. Previous Western Australian skin UV Index research has yielded findings of moderate awareness. However, there is the association between skin cancer prevalence and the UV Index but a lack of knowledge and application of the UV Index as a means of preventative measures …

Full-Forward And, Macho Homos : Toward A Masculist Reframing Of Male Homosexuality, Kristian Guagliardo

Theses : Honours

The following work explores the nexus of male homosexuality and traditional masculinity.

The creative work examines the ways in which both patriarchal and popular, purportedly feminist or queer theorist cultures arbitrarily assign allegedly immanent feminine qualities to homosexual males even when these characteristics are not congruent with the male subject. This facet of western, and specifically Australian, culture is explored through the prism of a hegemonically masculine ‘country boy’ who finds that despite his own comportment and identity, he becomes culturally and socially feminised by virtue of his homosexuality alone. He experiences isolation, angst, anger and cognitive dissonance as he …

Identifying And Localizing Intracellular Nanoparticles Using Raman Spectroscopy, Jennifer Dorney, Franck Bonnier, Amaya Garcia, Alan Casey, Gordon Chambers, Hugh Byrne

Articles

Raman microscopy is employed to spectroscopically image biological cells previously exposed to fluorescently labelled polystyrene nanoparticles and, in combination with K-means clustering and Principal Component Analysis (PCA), is demonstrated to be capable of localising the nanoparticles and identifying the subcellular environment based on the molecular spectroscopic signatures. The neutral nanoparticles of 50 nm or 100 nm, as characterised by dynamic light scattering, are shown to be non-toxic to a human lung adenocarcinoma cell-line (A549), according to a range of cytotoxicity assays including Neutral Red, Alamar Blue, Coomassie Blue and (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). Confocal fluorescence microscopy identifies intracellular fluorescence due to …

Schedularity In U.S. Taxation, Its Effect On Tax Distribution, Comparison With Sweden, Henry Ordower

All Faculty Scholarship

The United States derives from a global income tax model under which it taxes it citizens and permanent residents on all their worldwide income without regard to the source of that income. Under a pure global model, the United States would combine income and deductions in a single tax computation. Other countries including Germany and Sweden originate in schedular income tax models under which the tax system classifies income by type, matches it with deductions from the same class, and computes a separate tax on each class. Neither the United States’ global model nor Germany’s or Sweden’s schedular models are …

International Trade And Investment Law And Carbon Management Technologies, Steve Charnovitz

GW Law Faculty Publications & Other Works

Reducing emissions of greenhouse gases will require the development of carbon management technologies that are not currently available or that are not currently cost-effective. While market mechanisms such as carbon pricing must play a central role in stimulating the development of these technologies, governmental policy aimed at fostering carbon management technologies and lowering their costs must also play a part. Both types of policies will form part of an optimal greenhouse gas control portfolio. This article develops a framework of international trade and investment law insofar as they may affect carbon management technologies. While it is commonly perceived that international …

GW Law Faculty Publications & Other Works

In recent years the United Kingdom and various other countries have decided to restructure the institutions responsible for enforcing competition laws. How should a nation choose among myriad alternative arrangements? This paper lays out nine major institutional choices that governments must address in designing the implementation mechanism for a competition law. The paper discusses tradeoffs associated with each choice and examines interdependencies among different design elements. In doing so, the paper offers a structured framework that countries can use in forming new competition systems or altering existing institutional arrangements.

A House Of Cards Falls: Why 'Too Big To Debar' Is All Slogan And Little Substance, Jessica Tillipman

GW Law Faculty Publications & Other Works

“A House of Cards Falls: Why ‘Too Big to Debar’ is All Slogan and Little Substance” is a critical response to the article, "FCPA Sanctions: Too Big to Debar" by Drury D. Stevenson and Nicholas J. Wagoner, which aptly demonstrates a common, yet fundamentally flawed understanding of the FAR 9.4 suspension and debarment regime. "Too Big to Debar" asserts that when large government contractors violate the Foreign Corrupt Practices Act (FCPA), they should be “punished” by being debarred from the procurement system. Indeed, despite FAR 9.4’s clear directive to use debarment only for the purpose of protecting the government, not …

Emerging Policy And Practice Issues (2011), Steven L. Schooner, David J. Berteau

GW Law Faculty Publications & Other Works

This paper, presented at the West Government Contracts Year in Review Conference (covering 2011), attempts to identify the key trends and issues for 2012 in U.S. federal procurement. It begins from the premise that the most significant emerging issue in government contracting, looking ahead, is the money (or lack of it). As the fiscal belt tightens, the procurement landscape - what the government buys, from whom, and how - will necessarily change. Consistent with prior practice, this chapter offers extensive coverage of the federal procurement spending trend and attempts to predict what lies ahead. It also discusses the proliferation of …

From Start To Finish: A Historical Review Of Nuclear Arms Control Treaties And Starting Over With The New Start, Lisa M. Schenck, Robert A. Youmans

GW Law Faculty Publications & Other Works

This article provides a historical review of nuclear arms control agreements from 1925 to 2011, describing how these agreements helped diminish the nuclear arms threat and build up. As this article explains, nuclear arms control agreements can be segmented into distinct periods reflecting different approaches to the nuclear arms threat, with each stage addressing different focused objectives. As negotiations evolved throughout history, the United States and Soviet Union undertook a nuclear arms race, each striving to gain a military advantage over the other by building more and more nuclear weapons and the means to deliver them. Accordingly, a debate evolved …

Geoengineering And The Science Communication Environment: A Cross-Cultural Experiment, Donald Braman, Dan M. Kahan, Hank C. Jenkins-Smith, Tor Tarantola, Carol L. Silva

GW Law Faculty Publications & Other Works

We conducted a two-nation study (United States, n = 1500; England, n = 1500) to test a novel theory of science communication. The cultural cognition thesis posits that individuals make extensive reliance on cultural meanings in forming perceptions of risk. The logic of the cultural cognition thesis suggests the potential value of a distinctive two-channel science communication strategy that combines information content (“Channel 1”) with cultural meanings (“Channel 2”) selected to promote open-minded assessment of information across diverse communities. In the study, scientific information content on climate change was held constant while the cultural meaning of that information was experimentally …

Mobility Measures, Naomi Schoenbaum

GW Law Faculty Publications & Other Works

Geographic mobility is a celebrated feature of American life. Deciding where to live is seen not only as a key personal freedom, but also a means of economic advancement. Millions of Americans move each year over great distances. But while this right to travel is safeguarded by the Constitution, these mobility decisions are not entirely free. In terms of moving long distances, employment and family reasons are central, and a regime of employment and family law “mobility measures” play a significant role in regulating why and how we move. This Article first sets forth this new framework of “mobility measures,” …

Comparative Microbial Sampling From Eutrophic Caves In Slovenia And Slovakia Using Rida ®Count Test Kits, Janez Mulec, Václav Krištůfek, Alica Chroňáková

International Journal of Speleology

RIDA®COUNT test plates were used as an easy-to-handle and rapid indicator of microbial counts in karst ecosystems of several caves in Slovakia and Slovenia. All of the caves had a high organic input from water streams, tourists, roosting bat colonies or terrestrial surroundings. We sampled swabs, water and air samples to test robustness and universality of the RIDA®COUNT test kit (R-Biopharm AG, Germany, http://www.r-biopharm.com/) for quantification of total bacteria, coliforms, yeast and mold. Using data from swabs (colony-forming units per cm²) we proposed a scale for description of biocontamination level or superficial microbial load of cave niches. Based …

Women In The Post-Conflict Process: Reviewing The Impact Of Recent U.N. Actions In Achieving Gender Centrality, Naomi R. Cahn

GW Law Faculty Publications & Other Works

The post-conflict terrain provides multiple opportunities for transformation on many different levels: protecting civilians, providing accountability for human rights violations committed during hostilities, reforming local and national laws, reintegrating soldiers, rehabilitating and providing redress for victims, establishing or re-establishing the rule of law, creating human rights institutions and new governance structures, altering cultural attitudes, improving socioeconomic conditions, and transforming gender roles and women’s status. This Article explores the effort to make gender central in the various legal and political regimes and processes in operation post-conflict, and specifically reviews SCR 1325 and its successor resolutions to assess their real contributions towards …

Diagenesis Of A Drapery Speleothem From Castañar Cave: From Dissolution To Dolomitization, Andrea Martín-Pérez, Rebeca Martín-García, Ana M. Alonso-Zarza

International Journal of Speleology

A drapery speleothem (DRA-1) from Castañar Cave in Spain was subjected to a detailed petrographical study in order to identify its primary and diagenetic features. The drapery’s present day characteristics are the result of the combined effects of the primary and diagenetic processes that DRA-1 underwent. Its primary minerals are calcite, aragonite and huntite. Calcite is the main constituent of the speleothem, whereas aragonite forms as frostwork over the calcite. Huntite is the main mineral of moonmilk which covers the tips of aragonite. These primary minerals have undergone a set of diagenetic processes, which include: 1) partial dissolution or corrosion …

Provenance And Geological Significance Of Red Mud And Other Clastic Sediments Of The Mugnano Cave (Montagnola Senese, Italy), Francesco Iacoviello, Ivan Martini

International Journal of Speleology

The Mugnano cave is characterized by a thick clastic sedimentary fill showing a great variability of sedimentary facies, ranging from clay to coarse-grained sand deposits. This paper deals with combined sedimentological and mineralogical (XRD and SEM) studies of these sediments and bedrock insoluble residues in order to understand the origin and geological significance of cave deposits, with particular attention to red mud sediments, often considered as the residue of host rock dissolution. Three different sedimentary facies were recognized: i) YS, yellow sand with occasionally shell fragments, testifying the arrival of sediments from the surrounding landscape; ii) RS, red laminated mud; …

A Case Study Of A Servant Leadership Program At A Private, Faith-Based Academy, Lisa Coscia

Abraham S. Fischler College of Education ETD Archive

The private, faith-based academy under study did not have an intentional strategy or program for developing and preparing students to be Christian leaders in their school, community, and world. Although biblical instruction is integrated as a vital component of the curriculum; an intentional leadership program through which students could practice their faith had never been effectively established or implemented at the academy. The students need practical application to have a better understanding of their faith and to grow spiritually as servant leaders.

The purpose of this single-case study was to describe and explain a servant leadership program for juniors and …

An Investigation On Self-Esteem And Battered Women In A Shelter In Belize: A Guide To Treatment Intervention, Dorla E. Rosado

Abraham S. Fischler College of Education ETD Archive

The problem investigated involved the increasing numbers of reported cases of domestic violence in Belize between 2000 and 2009. As a result of this situation, the purpose of this applied research was to investigate the self-esteem of battered women who access the services of a shelter in Belize. This first of its kind study in Belize provided baseline data on the self-esteem of battered women to guide the development and implementation of treatment intervention for the women. Key to developing any treatment intervention is that the format is based on data-driven evidence that indicates how battered women in the shelter …

An Evaluation Of The Instructional Practices In Voice Teaching At Australian Performing Art Institutions, Ann Adlem

Theses: Doctorates and Masters

The purpose of this study was to identify and evaluate the practices and techniques of vocal training for student actors at a tertiary level, through a survey of experienced voice practitioners in Australian performing arts schools, appropriate texts, consideration of contexts and my own professional experience. Vocal instruction starts with the basic training of ‘the instrument’ or the vocal capabilities of the body. Following this or concurrent with its teaching, more specific forms of training are addressed. This research project used qualitative research methods to compile a detailed description of the voice teaching practices currently used in Australia. It comprises …

Development Of Capillary Electrophoresis For The Analysis Of Phenolics And Glucoraphanin In Brassica Oleracea, Iris Lee

Theses: Doctorates and Masters

Capillary electrophoresis (CE) has been used increasingly more over the last decade in the area of food analysis. Numerous food products and food components have been analysed using this technique because of its high efficiency and short separation times. However, the inherent lack of detection sensitivity in CE combined with the complex matrices present in many food samples, especially those of plant origins, is one of the contributing factors to the limited development on CE in this particular area of food analysis. In this project, the potential of CE as a tool in the analysis of vegetables belonging to the …

Uncertain Surrenders: The Coexistence Of Beauty And Menace In The Maternal Bond And Photography, Toni Wilkinson

Theses: Doctorates and Masters

This creative inquiry is grounded in my maternal experiences and situated within a feminist approach to photography that develops a discussion of maternal passion and acknowledges the conflicting dynamics of the maternal relationship. The research includes a book of photographs of my children, Georgia and Henry, titled Uncertain surrenders, and a written component explicating the theoretical imperatives that motivated the project. I suggest that the coexistence of beauty and menace within the photographic portraits exquisitely represents the complexity of maternal passion. Julia Kristeva (2005) says, “we lack a reflection on maternal passion” in Western culture because it is an ambiguous …

Mid West–Gascoyne District Police Officers’ Experience With The Cannabis Infringement Notice Scheme, Kara Wright

Theses: Doctorates and Masters

Cannabis is currently the most frequently used illicit drug in Australia. Research has revealed a range of health, economic, criminal and social consequences associated with the drug. The widespread use of cannabis and the consequences associated with its use has ignited strong political and social debate as to what response should be taken to minimise the harmful effects of the drug. In order to reduce the harms associated with cannabis, and in line with the national harm minimisation framework, the Western Australia (WA) Cannabis Infringement Notice (CIN) scheme commenced in 2004. The introduction of the CIN scheme as part of …

Interpersonal Psychotherapy For Depressed Retirees: Developing And Testing A Clinical Treatment Manual, Sue G. Miller

Theses: Doctorates and Masters

Most workers adjust well to retirement, but some experience depression due to poor adjustment. No evidence-based treatments were identified that targeted the developmental needs of this complex transition. In phase 1, a treatment manual (IPT-RM) was developed. The manual comprised an adaptation of Interpersonal Psychotherapy. In phase 2, a pilot study was conducted to determine the treatment’s feasibility. A series of non-experimental AB singlecase studies was conducted with nine retirees. All research participants’ depressive symptoms receded into the non-depressed range by the end of the study. The IPT-RM treatment manual was developed to a Stage 1 level, which incorporated peer-reviewed …

Theses: Doctorates and Masters

This thesis comprises an organisational history of the War Widow' Guild Australia WA Inc., and an essay about the research and writing process I undertook to construct such a history. The history outlines the development, struggles and achievements of the War Widows’ Guild in Western Australia from 1946 to 1975. While many were celebrating the end of the war in 1945, thousands of war widows faced an uncertain future without their husbands. Although Prime Minister John Curtin addressed the issue of war widows' pensions as part of his Post War Reconstruction initiatives, the pension was well below the basic wage. …

Causes And Effects Of Physical Injuries To Prison Officers Employed In A High Risk And High Need Offender Management Environment In Western Australia, Bigboy Ngwenya

Theses: Doctorates and Masters

Prison Officers (POs) involved in high need offender management frequently face risks that could affect their health, safety and wellbeing. Several studies have shown that direct client centred violence, inadequate management systems and the general nature of prison environments are major factors impacting on the well being of POs (Fisher & Gunnison, 2001; Kiekbusch, Price, & Theis, 2003; Mitchell, Mackenzie, Styve, & Gover, 2000).There is limited literature on causes and effects of physical injuries on this group of law enforcements officers. This is the first study conducted in Western Australia (WA) that investigated the causes and effects of physical injuries …
