Licensee MDPI, Basel, Switzerland.Organic light emitting transistors (OLETs) combine, in the same device, the function of an electrical switch with the capability of generating light under appropriate bias conditions. In this work, we demonstrate how engineering the dielectric layer based on high-k polyvinylidene fluoride (PVDF)-based polymers can lead to a drastic reduction of device driving voltages and the improvement of its optoelectronic properties. We first investigated the morphology and the dielectric response of these polymer dielectrics in terms of polymer (P(VDF-TrFE) and P(VDF-TrFE-CFE)) and solvent content (cyclopentanone, methylethylketone). Implementing these high-k PVDF-based dielectrics enabled low-bias ambipolar organic light emitting transistors, with reduced threshold voltages (<20 V) and enhanced light output (compared to conventional polymer reference), along with an overall improvement of the device efficiency. Further, we preliminary transferred these fluorinated high-k dielectric films onto a plastic substrate to enable flexible light emitting transistors. These findings hold potential for broader exploitation of the OLET platform, where the device can now be driven by commercially available electronics, thus enabling flexible low-bias organic electronic devices.Peer reviewe

The Nurse of Elfland: Lizzie Endicott and C.S. Lewis
No full textIn Surprised by Joy, C.S. Lewis introduced Lizzie Endicott as the first of two other blessings in his childhood, even before his introduction of Warnie. But apart from his abbreviated 136-word biography, very little is known about the nurse who introduced Lewis to faery tales. Based on the Lewis Family Papers, genealogical research, and personal interviews with Lizzie’s relatives, this article introduces Lizzie to the world of Lewismania. It also suggests various ways in which Lizzie influenced the man and the author that C.S. Lewis became, as well as the mythical worlds he created and Lewis’s anonymous tributes to her

Previously recorded from Lesotho (Dirsh 1956b), and South Africa (Uvarov 1922, Dirsh 1956b). Remarks. The genus Calliptamicus was erected by Uvarov (1922) on the basis of its peculiar slender hind femora and the shape of its male genitalia. So far, its taxonomic status is stable or satisfactory although the two nominate species are very similar in appearance and their species boundaries require investigation.Published as part of Tshililo, Precious, 2020, Review of South African Euryphyminae, pp. 70-104 in Zootaxa 4820 (1) on pages 84-85, DOI: 10.11646/zootaxa.4820.1.4, http://zenodo.org/record/439731
Grasshopper and butterfly local congruency in grassland remnants
No full textGrasshoppers could be considered as appropriate ecological indicators for grasslands owing to their sensitive response to environmental features. However, if grasshoppers are a good ecological indicator, they must (i) also represent other taxa, and (ii) provide additional information over straight measurement of environmental variables. To assess this, we compared the congruence of species richness patterns of grasshoppers with butterflies and environmental variables in two areas with extensive ecological networks (ENs). ENs are landscape-scale remnants of corridors and nodes of natural habitat running throughout a transformed, usually agricultural, landscape. Species richness of grasshoppers and butterflies did not differ among reference and EN sites, but guild composition differed significantly. While ENs adequately conserved overall diversity of these two groups, they were utilized preferentially by small-sized grasshoppers and shrub and tree-feeding butterflies. Reference sites had significantly more graminivorous and intermediate-mobility grasshopper species, as well as more butterfly species with widespread distribution, herbaceous dicot feeders and those with no recorded association to forest edges. Nevertheless, grasshopper and butterfly species richness' were highly correlated. These results were similar across geographic areas, despite the fact that the areas differed significantly in their overall richness and species composition. Although there were some specific significant correlations between environmental variables and diversity, none of the variables could adequately replace use of the insect assemblage for bioindication. We conclude that grasshopper species and guild richness are representative of the butterfly assemblage, and provide information which is not sufficiently clear when utilizing only environmental variables. © 2011 Springer Science+Business Media B.V
C.S. Lewis as Transformational Leader
No full textThe term leadership usually evokes images of great warriors, politicians, or social figures that saturate the pages of a history textbook. However, these are pre-conceived notions of the term. Leaders are those who exercise influence, be they soldiers, politicians, or even artists such as writers and musicians. One such leader is author and apologist C.S. Lewis. Lewis spoke to his generation (and many subsequent ones) in his texts. Through Lewis, many have achieved a greater understanding of literature, spirituality, and human nature. His words have, in essence, transformed the minds of readers.
Transformational leadership is desired because it performs what is implied in its title: it transforms others. Transformational leaders increase both motivation and morality in their followers. They lead with conviction, ultimately empowering followers to become leaders. Bass (1985) posits that transformational leaders exhibit four qualities: idealized influence, inspirational motivation, intellectual stimulation, and individualized consideration.
Upon exploring transformational leadership theory, it is evident that C.S. Lewis exhibits all four qualities of a transformational leader. Lewis has led many from the desert of spiritual ambiguity into a better understanding of God and of ourselves. His words still resonate in culture and demonstrate the lasting influence of his legacy
