Educational institutions rely on academic citizenship behaviors to construct knowledge in a responsible manner. However, they often struggle to contain the unlawful reuse of knowledge (or academic citizenship transgressions) by some learning communities. This study draws upon secondary data from two televised episodes describing contract cheating (or ghostwriting) practices prevalent among international student communities. Against this background, we have investigated emergent teaching and learning structures that have been extended to formal and informal spaces with the use of mediating technologies. Learners' interactions in formal spaces are influenced by ongoing informal social experiences within a shared cultural context to influence learners' agency. Building upon existing theories, we have developed an analytical lens to understand the rationale behind cheating behaviors. Citizenship behaviors are based on individual and collective perceptions of what constitutes as acceptable or unacceptable behavior. That is, learners who are low in motivation and are less engaged with learning may collude; more so, if cheating is not condemned by members belonging to their informal social spaces. Our analytical lens describes institutional, cultural, technological, social and behavioral contexts that influence learner agency.

Australia, like many other countries around the world, is undergoing a transition toward net zero emissions. It requires changes and development in many sectors, which not only bring benefits but also challenges. The rapid growth in renewable energy sources (RESs) is necessary to decarbonise electricity generation but negatively affects grid stability. Residential buildings also contribute to this issue through specific load profiles and the high penetration of rooftop photovoltaic (PV) installations. Maintaining grid balance will be crucial for further emissions reductions. One of the potential solutions can be the replacement of conventional heating and cooling systems in houses with solutions capable of storing energy and shifting the electrical load. As presented in this paper, heat pumps and hydronic systems can significantly improve the electrical load of a typical South Australian household when they are controlled by algorithms reacting to the current grid conditions and household-generated electricity compared to conventional solutions. TRNSYS 18 simulations of air source and ground source heat pump systems with smart control based on measured electricity consumption and domestic hot water usage data showed the possibility of total energy consumption reduction, shifting the load from peak periods towards periods of excessive RES generation and increasing self-consumption of rooftop PV electricity. These improvements reduce the amount of emissions generated by such a household and allow for further development of other sectors. [ABSTRACT FROM AUTHOR]

Introduction: Medical abortion while a necessity is a social taboo depending upon the situations. Since ancient times, numerous methodologies have been employed for carrying out abortions. Developments in medical sciences have made the procedure easy by use of some abortive drugs like Mifepristone and Misoprostol. However, these drugs have been misused with impunity for forced abortions, especially for female foeticide. The study was conducted to standardize the method for identification of these drugs in forensic cases related to illegal abortions. Thin Layer Chromatography (TLC) and Fourier Transform - Infrared Spectroscopy (FTIR) technologies were employed for the same. Results: Various combinations of solvents were employed and it was observed that Mifepristone was best separated in Chloroform-Acetone (9:1) and Toluene-Ethyl acetate (7:3) solvent systems. A unique inverted foetus shaped spot of Mifepristone can be visualized with Dragondorff's reagent, Zwikker reagent and Iodine fumes. However, visualization of Misoprostol was difficult by Thin Layer Chromatography method with these developers. Fourier Transform - Infrared Spectroscopy analysis gave the positive results in both the drugs. Conclusion: The standardization of Thin Layer Chromatography for forensic identification of abortive drug (Mifepristone) was done in this study. FTIR can be concluded as the method of choice in the identification of Misoprostol in forensic cases. [ABSTRACT FROM AUTHOR]
