Conceptualising Early Career Teachers’ Agency And Accounts Of Social Action In Disadvantaged Schools, Margaret Kettle, Bruce Burnett, Jo Lampert, Barbara Comber, Naomi Barnes

Australian Journal of Teacher Education

This article examines the accounts of actions undertaken by Early Career Teachers (ECTs) recently graduated from a social justice-oriented Initial Teacher Education (ITE) program and employed in complex school settings with high levels of student diversity, disadvantage, and poverty. The study drew on theories of teacher agency and agency more broadly to examine the workshadowing observations of the teachers’ practice in classrooms augmented by their reflective accounts in interviews. The study found that the ECTs’ agency, or contextualised social action, can be conceptualised as temporally embedded social engagement directed at addressing their students’ cultural, social and academic needs. The teachers …

Gender Differences And Motivation For The Teaching Profession: Why Do Men Choose (Not) To Teach?, Ivana Pikić Jugović, Ana Maskalan, Tea Pavin Ivanec

Australian Journal of Teacher Education

The aim of this study was to explore gender differences in motivation for choosing teaching as a profession and perceptions of men’s demotivation for the choice of this profession. 279 preservice subject teachers from the University of Zagreb, Croatia, filled in the FIT-Choice Scale (Watt & Richardson, 2007) and the Demotivation of Men for Teaching Career Choice Scale. Results revealed that, regardless of their gender, preservice subject teachers were primarily motivated by the intrinsic and social utility values of teaching, while specific gender differences imply the importance of the role of social factors in men’s choice of this career. Low …

Gender And Stress Levels Among Pre-Service Teachers, Gretchen Geng, Leigh Disney, Richard Midford, Jenny Buckworth

Australian Journal of Teacher Education

All Rsif Scholars' Publications

Few investigations have focused on the potential uses of artisanal gold (Au) mine tailings, despite the fact that artisanal gold mining activity contributes to environmental issues such as greenhouse gas. Mineralogical characterizations of artisanal gold mine tailings in Miyove gold mine (Baradega and Masogwe) in Rwanda were investigated for potential utilization as a source of valuable gold, using the centrifugal separation technique. Results of X-ray diffraction analysis, energy dispersive X-ray spectroscopy, inductively coupled plasma mass spectrometry, inductively coupled plasma–optical emission spectroscopy, and X-ray fluorescence showed that artisanal gold mine tailings samples have significant amounts of gold to justify economical gold …

Can Gdp Be Predictive Of Fertility Rates In Sweden?, Hannah Coleman

Honors Program: Senior Projects (Public)

Fertility rates in a country vary and can be influenced by numerous different aspects of an individual’s life and the society in which they live. One aspect that may influence fertility rates at the national level is the gross domestic product (GDP). GDP is an indicator of a country’s economic productivity. Because fertility is linked to both economic development and individual resources, GDP may be a useful indicator of fertility rates. If so, knowing or predicting GDP could be used to project the fertility rates of a population years into the future. To determine if a reasonable connection between GDP …

Effects Of Hearing Aid Amplification On The Ability Of Individuals With Hearing Loss To Perceive Spectral Information, Angela Huebert, Marc Brennan

Honors Program: Senior Projects (Public)

Individuals with sensorineural hearing loss often struggle to understand speech even with the use of hearing aids; simply making sounds louder is not enough. Listeners decode various speech sounds with the help of spectral information, but how hearing aid amplification affects individuals’ ability to perceive those cues is not currently well understood. Altering the way hearing aids are programmed to provide amplification can potentially improve the ability of listeners with sensorineural hearing loss to access spectral information. The purpose of this study was to quantify the effects that hearing aid amplification has on the perception of spectral cues. Outcomes could …

Airport Noise As Public Bads: Comparative Remarks On Legal Challenges In Resolving The Neighbor Conflict Between The Airport And Landowners, Magdalena Habdas

Journal of Air Law and Commerce

Incompatible uses of land create neighbor conflicts connected with the notions of civil law immissions (non-trespassory invasions) or common law nuisance. These traditional instruments of resolving the neighbor conflict have their limitations when pollution (such as noise pollution produced by aviation) interferes with the use and enjoyment of land that affects numerous landowners. Lawmakers seek to resolve the neighbor conflict with public intervention in such circumstances. Instead of relying on the market, the state allocates entitlements, indicates how parties must behave, and prescribes the conditions under which lawmakers should conclude an agreement.

Interestingly, although the nuisance caused by airport noise …

Predicting Bearing Fault In The Drone Freight Industry: Legal Liability In Australia, Prue Vines, Anthony Song, Matthew Priestley, Elias Aboutanios

Journal of Air Law and Commerce

Many people are now aware of drones or remotely piloted aircraft (RPAs), and several others have predicted the significant impacts that drones will bring across society. Today, there is an expectation that drones will play a pivotal role in industries such as surveillance, security, surveying, construction, and freight transport. However, in all these cases, whenever a drone is flying over a populated area, it poses a danger to people or things on the ground. Perhaps the sector where the greatest risk of injury to the everyday person exists is the drone delivery industry. The drone freight industry is proliferating fast, …

Private Law Aspects Of Suborbital Flights: Second- And Third-Party Liability And Insurance, Tanja Masson-Zwaan

Journal of Air Law and Commerce

Two companies carried private citizens to the edge of space in July 2021. Although suborbital flights have so far taken place within one jurisdiction—they start and end in the same state, do not pass through foreign airspace, or meet both criteria—they will become international when transportation between two points in different states via outer space becomes a reality. International law is ambiguous about the regulation of suborbital flights; neither international air law nor international space law explicitly apply. It is also unclear which organization or institution should be mandated with the international regulation of suborbital flights. The legal uncertainties must …

Pulsed Nuclear Space Propulsion And International Law: Some Preliminary, Glenn Reynolds, Leigh Outten

Journal of Air Law and Commerce

Pulsed Nuclear Space Propulsion, researched in the 1950s and 1960s by such eminent physicists as Freeman Dyson, Ted Taylor, Theodore von Karman, and Hans Bethe, involves propelling large spacecraft using compact nuclear explosions from specialized atomic devices. This technology is often known by the name of the Air Force project in which it was developed: Orion. It has long been believed that the 1962 Limited Test Ban Treaty prohibits the use of nuclear pulse space propulsion. After a survey of the Orion project and its results and a review of the applicable law, this Article concludes that language in the …

Vertiports: Ready For Take-Off … And Landing, Benjamyn Scott

Journal of Air Law and Commerce

While aviation has been used in transportation for decades, the use of vertical takeoff and landing (VTOL) aircraft for large-scale, low-cost, green, sustainable, and integrated mobility in populated areas is a new phenomenon. Despite the importance of ground infrastructure for embarkation and disembarkation of passengers, cargo, and mail, questions remain on how these “vertiports” are or should be regulated and how they will relate to existing regulated ground infrastructure such as aerodromes, airports, and heliports. Therefore, several questions arise: what is a vertiport; how do vertiports relate to other aviation infrastructure; what are the legal implications of having different terms; …

Cabotage And Deregulatory Anomalies, Timothy M. Ravich

Journal of Air Law and Commerce

The strangest airline route in America is between Pago Pago and the Manu’a Islands in American Samoa. No U.S. carrier serves this “domestic” route. Therefore, it is the only route between two points in the United States (or, more accurately, its territories) that is regularly scheduled service by a non-U.S.-flagged airline. The Pago Pago–Manu’a Islands flight is thus an unprecedented and unique exception to a federal law that permits only U.S. carriers operating U.S.-registered aircraft to fly between U.S. states and territories. Under existing U.S. cabotage policies, moreover, states and U.S. territories are divested of all power to manage …

Corporate Resiliency And Relevancy In The Private Ordering Era, Megan Wischmeier Shaner

Faculty Articles

Firm-specific private ordering has flourished in the twenty-first century. Public companies are seeing more and more governance contracting in traditional venues such as the bylaws and charter, as well as in less conventional places like shareholder agreements and dual-class-like contracts. Decisions legitimizing private ordering in the corporate setting contain strong contractarian language and rely heavily on contract – and not corporate – principles to justify their holdings. In addition, recent statutory amendments have chipped away at traditionally mandatory features of the corporation, thereby reinforcing the contractual view of the corporate form and fueling the private ordering movement. All told, the …

A Comprehensive Review On The Decontamination Of Lead(Ii) From Water And Wastewater By Low-Cost Biosorbents, Jonas Bayuo, Mwemezi Rwiza, Kelvin Mtei

All Rsif Scholars' Publications

The disadvantages of conventional methods in water and wastewater management including the demand for high energy consumption, the creation of secondary toxic sludge, and operation cost are much too high for developing countries. However, adsorption using low-cost biosorbents is the most efficient non-conventional technique for heavy metals removal. The high adsorption capacities, cost-effectiveness, and the abundance of agricultural waste materials in nature are the important parameters that explain why these biosorbents are economical for heavy metals removal. The present investigation sought to review the biosorption of lead [Pb(II)] onto low-cost biosorbents to understand their adsorption mechanism. The review shows that …

Breast cancer (BC) is the most common type of cancer diagnosed in women. Among female cancer deaths, BC is the second leading cause of death worldwide. For estrogen receptor-positive (ER-positive) breast cancers, endocrine therapy is an effective therapeutic approach. However, in many cases, an ER-positive tumor becomes unresponsive to endocrine therapy, and tumor regrowth occurs after treatment. While some genetic mutations contribute to resistance in some patients, the underlying causes of resistance to endocrine therapy are mostly undetermined. In this study, we utilized a recently developed statistical approach to investigate the dynamic behavior of gene expression during the development of …

Faculty, Staff and Student Publications

Colorectal cancer (CRC) is the third leading cause of cancer death globally. Early detection and removal of precancerous polyps can significantly reduce the chance of CRC patient death. Currently, the polyp detection rate mainly depends on the skill and expertise of gastroenterologists. Over time, unidentified polyps can develop into cancer. Machine learning has recently emerged as a powerful method in assisting clinical diagnosis. Several classification models have been proposed to identify polyps, but their performance has not been comparable to an expert endoscopist yet. Here, we propose a multiple classifier consultation strategy to create an effective and powerful classifier for …

Amelogenesis imperfecta is a congenital disorder within a heterogeneous group of conditions characterized by enamel hypoplasia. Patients suffer from early tooth loss, social embarrassment, eating difficulties, and pain due to an abnormally thin, soft, fragile, and discolored enamel with poor aesthetics and functionality. The etiology of amelogenesis imperfecta is complicated by genetic interactions. To identify mouse amelogenesis imperfecta-related genes (mAIGenes) and their respective phenotypes, we conducted a systematic literature review and database search and found and curated 70 mAIGenes across all of the databases. Our pathway enrichment analysis indicated that these genes were enriched in tooth development-associated pathways, forming four …
