    The challenge of developing innovative science teachers with ICT

    Get PDF
    This article begins by reviewing some important software tools which have benefits for science teaching and then describes ways in which the teacher has an important influence on the success of ICT activities in the classroom. Through examples of how such tools may be used to create new activities, we discuss some of the skills and teaching approaches needed to exploit their potential for learning. We then look at a model of teacher development and suggest how the training materials developed by the ICT for Innovative Science Teachers Project might be used in future training courses to meet the challenge of a changing pedagogy with ICT

    Modular cytosine base editing promotes epigenomic and genomic modifications

    Prokaryotic and eukaryotic adaptive immunity differ considerably. Yet, their fundamental mechanisms of gene editing via Cas9 and activation-induced deaminase (AID), respectively, can be conveniently complimentary. Cas9 is an RNA targeted dual nuclease expressed in several bacterial species. AID is a cytosine deaminase expressed in germinal centre B cells to mediate genomic antibody diversification. AID can also mediate epigenomic reprogramming via active DNA demethylation. It is known that sequence motifs, nucleic acid structures, and associated co-factors affect AID activity. But despite repeated attempts, deciphering AID’s intrinsic catalytic activities and harnessing its targeted recruitment to DNA is still intractable. Even recent cytosine base editors are unable to fully recapitulate AID’s genomic and epigenomic editing properties. Here, we describe the first instance of a modular AID-based editor that recapitulates the full spectrum of genomic and epigenomic editing activity. Our ‘Swiss army knife’ toolbox will help better understand AID biology per se as well as improve targeted genomic and epigenomic editing

    Rules of engagement: The role of mistreatment from patients in the nurse, physician and advanced practice provider experience

    The objective of this study is to examine the incidence of reported stress due to mistreatment by patients toward clinicians and the role of mistreatment from patients along with organizational factors in clinician distress. A survey of clinicians was conducted at a large academic medical center, resulting in a final analytic sample of 1,682 physicians, nurses, advanced practice providers and clinical support staff. Nurses reported the greatest incidence of mistreatment by patients as a major stressor (18.69%), followed by Advanced Practice Providers (11.26%), Clinical Support Staff (10.36%), and Physicians (7.69%). Logistic regression analysis was conducted to determine the relationship of individual- and organization-level characteristics with the odds of reporting mistreatment from patients as a major stressor. Overall findings indicate that nurses and those who work in the ER and ambulatory or outpatient clinics were more likely to be stressed from mistreatment by patients than other clinicians. Stress due to mistreatment by patients was also associated with higher Well-Being Index (WBI) distress scores, rapid changes in workflows or policies, ongoing care of COVID-19 patients, under-staffing, and low perceived organizational support. Gender or sexual minorities (not identifying as male or female) and younger (18-34 years of age) healthcare workers were also more likely to experience stress from mistreatment by patients. Individual resilience was not statistically significantly associated with reported stress from mistreatment by patients. Organizations must examine expectations for patient and visitor behavior in tandem with service standards for clinicians toward patients.

    Formation of Cu3BiS3 thin films via sulfurization of Bi-Cu metal precursors

    Get PDF
    Thin films of Cu 3BiS 3 have been produced by conversion of stacked and co-electroplated Bi-Cu metal precursors in the presence of elemental sulfur vapor. The roles of sulfurization temperature and heating rate in achieving single-phase good quality layers have been explored. The potential loss of Bi during the treatments has been investigated, and no appreciable compositional difference was found between films sulfurized at 550°C for up to 16 h. The structural, morphological and photoelectrochemical properties of the layers were investigated in order to evaluate the potentials of the compound for application in thin film photovoltaics. © 2012 Elsevier B.V.

    No Veteran Left Behind

    Get PDF
    This Co-Learning Plan analyzed the demographics of returning veterans and military retirees, the range of skills these vets possess and the most common obstacles they will encounter. A list of programs serving veterans by state, including financing, training, assistance, etc. was compiled. Lastly, success stories of veterans who have overcome obstacles to find new niches for themselves were used to document and recommend best practices for helping veterans re-enter the workforce
