Biodeterioration of Incralac used for the protection of bronze monuments

Outdoor bronze sculptures are highly susceptible to corrosion in many environments and organic coatings are widely used for their protection. The purpose of this study was to determine the susceptibility of the commonly used coating Incralac to biodeterioration by microorganisms. A yeast was isolated from a bronze statue treated with Incralac and its ability to degrade Incralac was determined using growth curves, scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS). The organism grew slowly on Incralac in liquid culture, but SEM images demonstrated its ability to adhere to Incralac coated metal. Additionally, the yeast caused a rapid drop in the low frequency impedance of Incralac coated metal that was not observed under sterile conditions, indicating that the organism accelerated deterioration of the coating. The potential for microbial growth to accelerate deterioration of Incralac should be considered when developing a maintenance strategy for the protection of outdoor metal monuments.     

Systemetic changes process I: Beginning the journary

Conclusion In summary, the panelists defined systemic change as change involving 1) a fundamental shift in purpose or focus, 2) a thoughtful redesign of all the system components to be in harmony with the new system orientation, and 3) an emphasis on continual maintenance through reevaluation. In addition, the importance of human factors such as trust and respect, and on human processes such as communication and collaboration were emphasized. Finally, the panelists seemed to agree that systemic change would not be an easy journey — a high level of motivation toward a compelling vision would be required.     

The Assessment Skills and Knowledge Standards: Professionalizing the work of assessing student learning and development

Exploring the challenges experienced by international students during work-integrated learning in Australia

This study explores the challenges experienced by international students during Work Integrated Learning (WIL) in Australia. Student participation in WIL not only enhances individual student employability but also the attractiveness of Australia as a study destination. WIL, in particular work placements, is in high demand by international students who seek to gain relevant experience in their host country and increase their chances of employment post-study. Data were gathered from employers, academics and students on the challenges faced by international students during the WIL experience and how WIL is currently being managed for the international cohort. Stakeholders identified a number of challenges which impact on student performance and the success of their WIL experience. These include cultural differences, inflated expectations, difficulties managing assessment tasks, relatively weak language skills and an imbalance in the support needed by international students in comparison to what is on offer. Stakeholder strategies to manage these challenges are discussed.     

Resisting plateauing: Four veteran teachers’ stories

This paper describes and interprets the career experiences of four veteran secondary teachers and their ability to resist plateauing. Three areas of veteran teacher research informed this study: career stages, plateauing, and resiliency. In-depth phenomenological interviews were conducted to investigate and depict the meanings these teachers attached to their career experiences.Several factors emerged for each participant’s resilience. First, building leaders influenced their enthusiasm and professional growth. Second, positive effects on students’ lives affirmed their work. Third, interactions with colleagues promoted growth, and individual support systems helped them bounce back from career frustrations.
