Teaching Out-Of-Field In Western Australia, Andrew Mcconney, Anne Price

Australian Journal of Teacher Education

A former head of the American Federation of Teachers, Albert Shanker, once called out-of-field teaching education’s “dirty little secret” (Ingersoll, 2003, p. 5). The practice of allowing or assigning teachers to teach subjects or year levels for which they do not have any formal qualifications has lead to considerable debate within the educational community. Such concerns over the possible negative impact of out-of-field teaching on students, teachers and the broader school community led the Western Australian College of Teaching (WACOT) to commission an exploratory empirical study of the extent of the phenomenon in Western Australia. This paper presents the main …

Development Of A Fluorescent Probe For Determination Of Water Transport In Subcellular Organelles, Adriana Chaurra-Arboleda

All Dissertations

Water transport has been widely studied in a variety of cells and isolated membranes. However, the intrinsic complexity related with the study of intracellular processes has delayed the development of an analytical technique for the study of water transport in subcellular compartments of living cells. This study represents the development and application of a ratiometric fluorescent probe to study water transport in endocytic organelles of intact living cells. The probe is based on the use of a D₂O-sensitive fluorophore, Lucifer yellow dextran (LY-dex), together with a D₂O-insensitive fluorophore, Alexa fluor 546 dextran (AF546-dex), used as an …

An Approach Designed For Reginal Prospective Human Health And Ecological Risk Assessment And Its Application To Mercury Risks From A Coal-Fired Power Plant, Pathratipa Sansayavichai

All Dissertations

A large and/or long-term released source of a toxic chemical(s) can cause adverse effects to humans and non–human species inhabiting all over the region. The overall goal of this dissertation was to improve practices in risk assessment concerning a regional risk posed by a prospective source. A generic conceptual framework for performing regional prospective human health and ecological risk assessment was developed. The formulation of a priori considerations was used to identify the possible sources of uncertainties in the prospective risk assessment. Physiologically based pharmacokinetic (PBPK) modeling was utilized to reduce uncertainty in a toxicologically safe dose used in risk …

Interrupting The Workplace: Examining Stressors In An Information Technology Context, Pamela Galluch

All Dissertations

This dissertation focuses on the negative and positive outcomes of information and communication technology (ICT) in facilitating and reducing stress. The goals of this dissertation are twofold: 1) to deepen our understanding of how ICT-enabled interruptions influence individuals' episodic stress and 2) to examine whether ICTs may also be used to diminish stress evoked by ICT-enabled interruptions. Originating from psychology, the demands control model (Karasek, 1979) is used as an overarching theoretical lens to explain this technology-based duality, where technology serves as both a problem causing and a solution alleviating stress. The demands control model suggests that stressors have their …

Implementing Energy Release Rate Calculations Into The Lamodel Program, Morgan M. Sears

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mining activity at increasingly greater depths and the tragedy at Crandall Canyon that claimed the lives of nine miners have forced coal bump research to the forefront of mining engineering research. Near the end of the last century, the National Institute for Occupational Safety and Health (NIOSH) and the former U.S. Bureau of Mines investigated the mechanics, conditions, and mitigation of coal bumps. Unfortunately, the exact mechanics of coal bumps is still not fully understood. Following this period, research into coal bumps in the United States has been limited.;The Energy Release Rate (ERR) calculation quantifies the dissipation ("release") of the …

The 'Molar Tooth Sign' In Joubert Syndrome, Imaad Ur Rehman, Zablon Bett, Yousuf Husen, Ali Syed Muhammad Akhtar, Faisal Aziz Khan

Department of Radiology

The molar tooth sign is seen in very few conditions and is a very rare paediatric central nervous system congenital anomaly. Molar tooth sign is the result of cerebellar vermis hypoplasia, thick and maloriented superior cerebellar peduncles, and an abnormally deep interpeduncular fossa. In Joubert syndrome this is seen in about 85% of patients. We present a case of 13 months old baby boy with recurrent episodes of fits and hyperpnoea, regression of milestones and developmental delay. MRI examination showed the characteristic molar tooth sign with apposition of cerebellar hemispheres, batwing-shaped fourth ventricle communicating through a thin fissure with foramen …

Simple Cooling Method Improves The Quality Of Marketed Camel Milk In Northern Kenya, D. Layne Coppock, A. O. Adongo, F. Wayua, I. J. Sagalla, H. K. Walaga, C. Amboga

Environment and Society Faculty Publications

Milk marketing is important for many pastoralists to generate income, especially poor households with little else to sell. Milk is accumulated at pastoral settlements and transported to local markets on foot, by pack animals, or in vehicles. Despite challenges of heat and long-distance travel, pastoralists or traders do not attempt to cool marketed milk and possibly reduce risk of spoilage. Milk spoilage is an important problem that limits urban consumer demand. Our research objective was to determine effects of water-soaked hemp (burlap), wrapped around plastic jerry cans, on reducing milk temperature and enhancing quality of marketed camel milk, a key …

The Fiduciary Constitution Of Human Rights, Evan Fox-Decent, Evan J. Criddle

Faculty Publications

We argue that human rights are best conceived as norms arising from a fiduciary relationship that exists between states (or statelike actors) and the citizens and noncitizens subject to their power. These norms draw on a Kantian conception of moral personhood, protecting agents from instrumentalization and domination. They do not, however, exist in the abstract as timeless natural rights. Instead, they are correlates of the state’s fiduciary duty to provide equal security under the rule of law, a duty that flows from the state’s institutional assumption of irresistible sovereign powers.

The Relationship Between Procrastination And Intrapersonal Intelligence In College Students, Christa Grant

Theses and Dissertations

Procrastination is ubiquitous, encompasses many domains of life, i.e., school, work, and home, and for many people has negative results. Therefore, researchers, educators, psychologists, and counselors need to discover ways to alleviate the problem. When Gardner's multiple intelligences are used in pedagogical implementation in elementary and high schools, researchers have found positive results. The purpose of this study was to investigate the relationships between procrastination and intrapersonal intelligence as well as the other dimensions of multiple intelligence among students in higher education in order to illuminate possible solutions to the problem of procrastination. Because intrapersonal intelligence is associated with the …

Thermoregulation Of Capsule Production Of Streptococcus Pyogenes Strain Hsc5, Trilce Michelle Galeas

Theses

Group A Streptococcus (GAS) is responsible for mild and common infections like tonsillitis and pharyngitis, and more serious invasive disorders like necrotizing fasciitis and glomerulonephritis. The ability to invade tissues is closely linked to the virulence factors expressed by the bacterium. Hyaluronic acid capsule expression is variable among all the strains in S. pyogenes and confers the capacity to evade the immune response. In a previous study, it was found that capsule production in CovR mutants was temperature-regulated, showing no capsule production at 37℃ but increased production was observed at 25℃. In this study, the objective is to find the …

Feeling Comfortable With Pluralistic Diversity: Using Common Organizational Strategies To Get Uncommon Results In Higher Education Voluntary Service Organizations, Ruth Sessler Bernstein

Student Scholarship

Diversity is a goal of the majority of America's institutions of higher learning. These colleges and universities have made great strides in achieving representational diversity through aggressive recruiting and retention efforts. However, on campus, students infrequently engage in pluralistic diversity. This paper examines a national voluntary service organization at two pluralistically diverse universities. Semi-structured interviews with members and alumni of the association provided insight into the characteristics of the interactions they have had with those who are different from them. These insights enabled us to examine the specific organizational strategies this nonprofit adopted that promoted enriching intercultural interactions.

From Esteem To Stigma: The Effect Of The Financial Crisis On Banker Engagement, Glen Weaver

Student Scholarship

Absent from a quickly accumulating literature on job engagement is a focus on professionals in the financial industry. There is, in particular, little research on the organization or industry identity of bankers as a discrete group. Nor has the literature explored the relationship of these identities with job engagement or environmental duress. We seized an opportunity to study the effects of the 2007-2009 financial crisis on bankers' identities and passion for their jobs. Semi-structured interviews with 28 mid-level bankers at five prominent US banks that accepted Toxic Asset Relief Program funding (TARP) captured insights about "normal state" (pre-crisis) versus mid-crisis …

The Effects Of Strategic Outsourcing Management On Absorptive Capacity: A Practioner-Scholar Perspective, Beth Fitz Gibbon

Student Scholarship

Common sense would say, if you are going to outsource innovation, find the most competent supplier and acquire the most codified technology. This research hypothesizes a more counter-intuitive approach by empirically measuring how a firm's outsourcing strategy affects its Absorptive Capacity, which serves here as a proxy for firm sustainability. It is proposed that a complementary buyer-supplier relationship will have a significant positive effect on a firm's absorptive capacity, thereby enhancing its long-term effectiveness, as well as its short-term efficiency. On the other hand, the more competent the supplier relative to the buyer, the less knowledge the outsourcing buyer will …

The Paradox Of Evidenced-Based Management In Higher Education, Alice J. Walker

Student Scholarship

The potential role for evidence-based management approaches to transform systems of higher learning and meet the growing needs of our knowledge economy is widely proposed. Most of the empirical work on evidence-based practice and management has concentrated on dynamics directly related to the use of evidence. This study takes a broader view of the management process of inquiry in which evidence is collected, interpreted or ignored. Semi-structured interviews with 31 faculty, staff and administrative members of college quality improvement committees were conducted in a grounded approach to qualitative research. What emerged was an intriguing tale of passion, power, and paradox …

The Role Of School Leadership In Student Achievement In Kenya, Renson Muchiri Mwangi

Student Scholarship

Despite ample documentation that mathematics mastery can affect national development and notwithstanding long instituted formal government initiatives to improve it, student mathematics performance at the secondary school level in Kenya has deteriorated. Studies on mathematics achievement in Kenya have primarily focused on teachers’ classroom practices neglecting the potential influence of school leadership. We conducted a qualitative study involving Kenyan school principles and other administrative and instructional staff to construct an account of how school leadership is enacted and experienced in the day-to-day practices and how it affects student mathematics mastery. Our findings suggest that principals’ leadership and engagement, demonstrated commitment, …

Analysis Of Relations And Forces Of Production In Extraction And Pearl Industry In The Arabian Gulf 1900-1950, Tawfik Younan

Journal of Economics and Administrative Sciences

Due to limited natural resources, the inhabitants of the Arabian Gulf historically oriented their primary activities toward the sea, with fishing and the pearl industry serving as the cornerstone of employment and the creation of economic surplus in the region. The significance of this sector intensified particularly after the mid-nineteenth century, driven by the global prosperity of the pearl trade and the Gulf’s integration with European nations undergoing rapid industrialization, which in turn introduced higher quality and more affordably priced goods to the region. By the first quarter of the twentieth century, the workforce in this industry accounted for no …

Firm-Specific Knowledge Resources And Competitive Advantage: The Roles Of Economic- And Relationship-Based Employee Governance Mechanisms, Heli Wang, Jinyu He, Joseph T. Mahoney

Research Collection Lee Kong Chian School Of Business

The resource-based view of the firm emphasizes the role of firm-specific resources, especially firm-specific knowledge resources, in helping a firm to achieve sustainable competitive advantage. However, the deployment of firm-specific knowledge often requires key employees to make specialized human capital investments that are not easily redeployable to other settings. Thus, in the absence of effective safeguards and trust building devices, employees with foresight may be reluctant to make such specialized investments. This study explores both economic- and relationship-based governance mechanisms that might mitigate this underinvestment problem. Effective use of these governance mechanisms enables a firm to obtain greater performance from …
