Teaching for 3 Cs: centering imagination in teacher education
In view of globalization, bureaucratization, marketization and commercialization, the context of education has changed. In response, the critical capacities of student teachers need to be developed so that they better understand and empathize with one-another and are able to see the complexities of the world through multiple perspectives. This, in turn, necessarily requires nurturing of imagination, which we consider in relation to the 3Cs: Care, Critique and Creativity. We commence with an overview of current developments affecting education and review existing practices in teacher education. We then provide the context of a practicebased enquiry that used metaphors and objects to explore student teachers’ understanding of personal experiences. We conclude with connecting the reflective process of the enquiry to the nurturing of imagination and the 3Cs

A meta approach to texts in Religious Education: Researching teachers’ engagement with sacred text scholarship in English secondary schools
This article reports findings from a sacred text scholarship project in Religious Education / Religion and Worldviews (RE/RW) lessons. In the Texts and Teachers project secondary school teachers found that RE became more meta through a more scholarly treatment of texts, and led to leap moments with pupils who could accomplish multidimensional engagement with texts. This article contributes to an improved understanding of how classroom textual hermeneutics addresses concerns with teaching sacred texts
Religious education and hermeneutics: the case of teaching about Islam
This article attempts to do three things: the first is an exploration of the ways in which Islam is presented in an essentialist way (with a focus on Religious Education (RE) in England and Wales), leading to stereotypes and unsubstantiated generalisations. Secondly, it provides a critique of essentialism, and finally a case is made for the role of hermeneutics in the teaching and learning of Islam
Effect of two different heat transfer fluids on the performance of solar tower csp by comparing recompression supercritical co2 and rankine power cycles, china
China intends to develop its renewable energy sector in order to cut down on its pollution levels. Concentrated solar power (CSP) technologies are expected to play a key role in this agenda. This study evaluated the technical and economic performance of a 100 MW solar tower CSP in Tibet, China, under different heat transfer fluids (HTF), i.e., Salt (60% NaNO3 40% KNO3 ) or HTF A, and Salt (46.5% LiF 11.5% NaF 42% KF) or HTF B under two different power cycles, namely supercritical CO2 and Rankine. Results from the study suggest that the Rankine power cycle with HTF A and B recorded capacity factors (CF) of 39% and 40.3%, respectively. The sCO2 power cycle also recorded CFs of 41% and 39.4% for HTF A and HTF B, respectively. A total of 359 GWh of energy was generated by the sCO2 system with HTF B, whereas the sCO2 system with HTF A generated a total of 345 GWh in the first year. The Rankine system with HTF A generated a total of 341 GWh, while the system with B as its HTF produced a total of 353 GWh of electricity in year one. Electricity to grid mainly occurred between 10:00 a.m. to 8:00 p.m. throughout the year. According to the results, the highest levelized cost of energy (LCOE) (real) of 0.1668 USD/kWh was recorded under the Rankine cycle with HTF A. The lowest LCOE (real) of 0.1586 USD/kWh was obtained under the sCO2 cycle with HTF B. In general, all scenarios were economically viable at the study area; however, the sCO2 proved to be more economically feasible according to the simulated results. © 2021 by the authors.

Mindfulness-based interventions in epilepsy: a systematic review
Mindfulness based interventions (MBIs) are increasingly used to help patients cope with physical and mental long-term conditions (LTCs). Epilepsy is associated with a range of mental and physical comorbidities that have a detrimental effect on quality of life (QOL), but it is not clear whether MBIs can help. We systematically reviewed the literature to determine the effectiveness of MBIs in people with epilepsy. Medline, Cochrane Central Register of Controlled Trials, EMBASE, CINAHL, Allied and Complimentary Medicine Database, and PsychInfo were searched in March 2016. These databases were searched using a combination of subject headings where available and keywords in the title and abstracts. We also searched the reference lists of related reviews. Study quality was assessed using the Cochrane Collaboration risk of bias tool. Three randomised controlled trials (RCTs) with a total of 231 participants were included. The interventions were tested in the USA (n = 171) and China (Hong Kong) (n = 60). Significant improvements were reported in depression symptoms, quality of life, anxiety, and depression knowledge and skills. Two of the included studies were assessed as being at unclear/high risk of bias - with randomisation and allocation procedures, as well as adverse events and reasons for drop-outs poorly reported. There was no reporting on intervention costs/benefits or how they affected health service utilisation. This systematic review found limited evidence for the effectiveness of MBIs in epilepsy, however preliminary evidence suggests it may lead to some improvement in anxiety, depression and quality of life. Further trials with larger sample sizes, active control groups and longer follow-ups are needed before the evidence for MBIs in epilepsy can be conclusively determined
Enacting the Prevent Duty in Early Childhood Education Settings
This chapter examines the implementation of the Prevent Duty in early childhood education (ECE) provision in England. Findings from a small-scale empirical study suggest that ECE practitioners simultaneously performed, resisted and embodied the requirements of the Prevent Duty in practice. ECE practitioners were performative in their response to the requirement to promote fundamental British values (FBVs) as they evidenced compliance within an environment of regulation. However, ECE practitioners simultaneously operated a pedagogy rich in values education in which children were positioned as constructors of values. The layering of counter-terrorism within safeguarding policy led to a repositioning of practices of surveillance of children and families, which resonates with some critical readings of counter-terrorism policy in ECE
Effects of dietary plant-derived phytonutrients on the genome-wide profiles and coccidiosis resistance in the broiler chickens
<p>Abstract</p> <p>Background</p> <p>The present study was conducted to investigate the effects of dietary plant-derived phytonutrients, carvacrol, cinnamaldehyde and Capsicum oleoresin, on the translational regulation of genes associated with immunology, physiology and metabolism using high-throughput microarray analysis and <it>in vivo</it> disease challenge model of avian coccidiosis.</p> <p>Methods</p> <p>In this study, we used nutrigenomics technology to investigate the molecular and genetic mechanisms of dietary modulation of host innate immunity and metabolism by three phytonutrients. To validate their immunomodulatory effects in a disease model, young broiler chickens fed a standard diet supplemented with three phytochemicals (carvacrol, cinnamaldehyde, and Capsicum oleoresin) from one day post-hatch were orally challenged with <it>E. acervulina</it>. The body weight gain and fecal oocyst production were used to evaluate coccidiosis disease parameters.</p> <p>Results</p> <p>Analysis of global gene expression profiles of intestinal tissues from phytonutrient-fed birds indicated that Capsicum oleoresin induced the most gene changes compared to the control group where many of these genes were associated with those of metabolism and immunity. The most reliable network induced by dietary cinnamaldehyde treatment was related with the functions of antigen presentation, humoral immune response, and inflammatory disease. Furthermore, dietary supplementation with these phytonutrients significantly protected broiler chickens against live coccidiosis challenge infection based on body weight and parasite fecundity.</p> <p>Conclusions</p> <p>The results of this study provide clear evidence to support the idea that plant-derived phytochemicals possess immune-enhancing properties in chickens and these new findings create a new possibility to develop effective drug-free alternative strategies for disease control for poultry infectious diseases.</p
Deoxyribonucleic Acid Encoded and Size-Defined π-Stacking of Perylene Diimides.
Funder: University of CambridgeNatural photosystems use protein scaffolds to control intermolecular interactions that enable exciton flow, charge generation, and long-range charge separation. In contrast, there is limited structural control in current organic electronic devices such as OLEDs and solar cells. We report here the DNA-encoded assembly of π-conjugated perylene diimides (PDIs) with deterministic control over the number of electronically coupled molecules. The PDIs are integrated within DNA chains using phosphoramidite coupling chemistry, allowing selection of the DNA sequence to either side, and specification of intermolecular DNA hybridization. In this way, we have developed a "toolbox" for construction of any stacking sequence of these semiconducting molecules. We have discovered that we need to use a full hierarchy of interactions: DNA guides the semiconductors into specified close proximity, hydrophobic-hydrophilic differentiation drives aggregation of the semiconductor moieties, and local geometry and electrostatic interactions define intermolecular positioning. As a result, the PDIs pack to give substantial intermolecular π wave function overlap, leading to an evolution of singlet excited states from localized excitons in the PDI monomer to excimers with wave functions delocalized over all five PDIs in the pentamer. This is accompanied by a change in the dominant triplet forming mechanism from localized spin-orbit charge transfer mediated intersystem crossing for the monomer toward a delocalized excimer process for the pentamer. Our modular DNA-based assembly reveals real opportunities for the rapid development of bespoke semiconductor architectures with molecule-by-molecule precision.ERC Horizon 2020 (grant agreement No 670405 and No 803326)
