AbstractThe influences of reactor pressure on the stoichiometry, free carrier concentration, IR and Hall determined mobility, effective optical band edge, and optical phonon modes of HPCVD grown InN films have been analysed and are reported. The In 3d, and N 1s XPS spectra results revealed In‐N and N‐In bonding states as well as small concentrations of In‐O and N‐O bonds, respectively in all samples. InN layers grown at 1 bar were found to contain metallic indium, suggesting that the incorporation of nitrogen into the InN crystal structure was not efficient. The free carrier concentrations, as determined by Hall measurements, were found to decrease with increasing reactor pressure from 1.61×1021 to 8.87×1019 cm‐3 and the room‐temperature Hall mobility increased with reactor pressure from 21.01 to 155.18 cm2/Vs at 1 and 15 bar reactor pressures, respectively. IR reflectance spectra of all three (1, 8, and 15 bar) InN samples were modelled assuming two distinct layers of InN, having different free carrier concentration, IR mobility, and effective dielectric function values, related to a nucleation/interfacial region at the InN/sapphire, followed by a bulk InN layer. The effective optical band gap has been found to decrease from 1.19 to 0.95 eV with increasing reactor pressure. Improvement of the local structural quality with increasing reactor pressure has been further confirmed by Raman spectroscopy measurements. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Abstract
We and others have previously demonstrated that retinal cells can be derived from human embryonic stem cells (hESCs) and induced pluripotent stem cells under defined culture conditions. While both cell types can give rise to retinal derivatives in the absence of inductive cues, this requires extended culture periods and gives lower overall yield. Further understanding of this innate differentiation ability, the identification of key factors that drive the differentiation process, and the development of clinically compatible culture conditions to reproducibly generate functional neural retina is an important goal for clinical cell based therapies. We now report that insulin-like growth factor 1 (IGF-1) can orchestrate the formation of three-dimensional ocular-like structures from hESCs which, in addition to retinal pigmented epithelium and neural retina, also contain primitive lens and corneal-like structures. Inhibition of IGF-1 receptor signaling significantly reduces the formation of optic vesicle and optic cups, while exogenous IGF-1 treatment enhances the formation of correctly laminated retinal tissue composed of multiple retinal phenotypes that is reminiscent of the developing vertebrate retina. Most importantly, hESC-derived photoreceptors exhibit advanced maturation features such as the presence of primitive rod- and cone-like photoreceptor inner and outer segments and phototransduction-related functional responses as early as 6.5 weeks of differentiation, making these derivatives promising candidates for cell replacement studies and in vitro disease modeling.

Resistin Promotes Angiogenesis in Endothelial Progenitor Cells Through Inhibition of MicroRNA206: Potential Implications for Rheumatoid Arthritis

Abstract
Endothelial progenitor cells (EPCs) promote angiogenesis and are therefore key contributors to a wide variety of angiogenesis-related autoimmune diseases such as rheumatoid arthritis (RA). However, the signaling mechanisms through which these progenitor cells influence RA pathogenesis remain unknown. The aim of this study was to examine whether resistin plays a role in the pathogenesis of and angiogenesis associated with RA by circulating EPCs. We found that levels of resistin in synovial fluid and tissue from patients with RA and from mice with collagen-induced arthritis were overexpressed and promoted the homing of EPCs into the synovium, thereby inducing angiogenesis. EPCs isolated from healthy donors were used to investigate the signal transduction pathway underlying EPC migration and tube formation after treatment with resistin. We found that resistin directly induced a significant increase in expression of vascular endothelial growth factor (VEGF) in EPCs. We also found that the expression of microRNA-206 (miR-206) was negatively correlated with the expression of resistin during EPC-mediated angiogenesis. Notably, the increased expression of VEGF was associated with decreased binding of miR-206 to the VEGF-A 3′ untranslated region through protein kinase C delta-dependent AMP-activated protein kinase signaling pathway. Moreover, blockade of resistin reduced EPC homing into synovial fluid and angiogenesis in vivo. Taken together, our study is the first to demonstrate that resistin promotes EPCs homing into the synovium during RA angiogenesis via a signal transduction pathway that involves VEGF expression in primary EPCs. These findings provide support for resistin as a therapeutic target for the patients with RA. Stem Cells 2015;33:2243–2255
Predictive control and sizing of energy storage to mitigate wind power intermittency
Authors: Li Chiao‐Ting , Peng Huei , Sun Jing 
Published: April 2015

AbstractThis paper studies how the control algorithm impacts the required capacity of battery energy storage system (BESS) to mitigate wind intermittency. We study a futuristic scenario in which wind generation is traded in the energy market on an hourly basis, and the wind power producer has to procure reserves to handle wind fluctuations. The wind power producer can avoid paying for conventional reserves by charging/discharging BESS to compensate for wind surplus and deficit. We develop control algorithms using the model predictive control (MPC) methodology, which incorporates wind forecasts for the next few hours when determining wind scheduling. The MPC algorithm is developed by solving a non‐linear optimization problem to minimize operation costs to the wind power producer. In addition to operation costs, the MPC algorithm considers two practical aspects: the efficiency loss of BESS and the smoothness in wind power scheduling. BESS sizing is studied by parametric analyses. Simulations show that BESS is more effective in reducing operation costs and reducing wind curtailment than conventional reserves. In addition, MPC is a horizon‐based control algorithm and can preview future information in its control action. Simulations also show that MPC consistently outperforms an instantaneous heuristic algorithm that does not use future information. Therefore, we confirm that MPC can reduce the BESS capacity required to cover wind uncertainties. Copyright © 2015 John Wiley & Sons, Ltd.
How Academics in Undergraduate Business Programs at an Australian University View Sustainability
Authors: von der Heidt Tania , Lamberton Geoffrey 
Published: April 2015

AbstractThis article explores conceptualisations of sustainability and perceptions of its importance in curriculum held by business subject and program leaders. Results are reported from an empirical study of the first-year Bachelor of Business program at an Australian university. Research data was collected in 16 semi-structured, in-depth interviews with subject and program leaders over two teaching periods in 2011. Interview transcripts were analysed through the identification of key themes. The results reveal that teaching academics believe sustainability is something more dynamic and complex than they are able to feature in their subjects, reflecting the difficulty in appropriately conceptualising sustainability, as well as differences between the academics’ beliefs, intentions and actions. Few studies explore the conceptualisations of sustainability held by subject and program leaders. If business schools are to produce sustainability-savvy graduates, the teaching academics need to have a clear and, ideally, shared view of sustainability.

Surviving a flood: effects of inundation period, temperature and embryonic development stage in locust eggs
Authors: Woodman J.D. 
Published: April 2015

AbstractThe Australian plague locust, Chortoicetes terminifera (Walker), is an important agricultural pest and oviposits into compacted soil across vast semi-arid and arid regions prone to irregular heavy summer rainfall. This study aimed to quantify the effects of flooding (control, 7, 14, 21, 28 and 35 days) at different temperatures (15, 20 and 25°C) and embryonic development stages (25 and 75%) on egg viability, hatchling nymph body mass and survival to second-instar. Egg viability after flooding was dependent on temperature and flood duration. Eggs inundated at 15°C showed ≥53.5% survival regardless of flood duration and development stage compared with ≤29.6% for eggs at 25°C for ≥21 days early in development and ≥14 days late in development. Hatchling nymphs did not differ in body mass relative to temperature or flood duration, but weighed more from eggs inundated early in development rather than late. Survival to second-instar was ≤55.1% at 15 and 20°C when eggs were flooded for ≥28 days late in development, ≤35.6% at 25°C when flooded for ≥28 days early in development, and zero when flooded for ≥21 days late in development. These results suggest that prolonged flooding in summer and early autumn may cause very high egg mortality and first-instar nymph mortality of any survivors, but is likely to only ever affect a small proportion of the metapopulation. More common flash flooding for ≤14 days is unlikely to cause high mortality and have any direct effect on distribution and abundance.

Published: April 2015

BackgroundTuberous sclerosis complex (TSC) is associated with intellectual disability, but the risk pathways are poorly understood.MethodThe Tuberous Sclerosis 2000 Study is a prospective longitudinal study of the natural history of TSC. One hundred and twenty-five UK children age 0–16 years with TSC and born between January 2001 and December 2006 were studied. Intelligence was assessed using standardized measures at ≥2 years of age. The age of onset of epilepsy, the type of seizure disorder, the frequency and duration of seizures, as well as the response to treatment was assessed at interview and by review of medical records. The severity of epilepsy in the early years was estimated using the E-Chess score. Genetic studies identified the mutations and the number of cortical tubers was determined from brain scans.ResultsTSC2 mutations were associated with significantly higher cortical tuber count than TSC1 mutations. The extent of brain involvement, as indexed by cortical tuber count, was associated with an earlier age of onset and severity of epilepsy. In turn, the severity of epilepsy was strongly associated with the degree of intellectual impairment. Structural equation modelling supported a causal pathway from genetic abnormality to cortical tuber count to epilepsy severity to intellectual outcome. Infantile spasms and status epilepticus were important contributors to seizure severity.ConclusionsThe findings support the proposition that severe, early onset epilepsy may impair intellectual development in TSC and highlight the potential importance of early, prompt and effective treatment or prevention of epilepsy in tuberous sclerosis.
The foundational efficiency of love: reconciling with Aquinas
Authors: Putt Sharon L. 
Published: April 2015

AbstractAnabaptist theologians who vie for the most convincing theory of divine non-violence in the contemporary ‘atonement debate’ quite often fail to appreciate the contributions of medieval scholars such as St Thomas Aquinas. Of course, that failure does have a rationale. Aquinas does, indeed, support various systematic expressions of a satisfaction theory of atonement. In doing so, he insists upon God's violent solution to the problem of sin and also employs language fraught with quid pro quo, mercantile and penal images. Aquinas does attempt to ‘correct’ Anselm and rearticulate the satisfaction theory of atonement; however, his expression of that motif still hinges upon the divine demand for remuneration, balanced accounts or an economic transaction in order to repair the damage done by sin. God's desire for this redemptive reparation results in the necessity of the violent death of an innocent man. Consequently, although Aquinas expresses the notion of necessity differently than Anselm, his theory also necessitates, at best, divine complicity with violence and, at worst, divine insistence on violence. Anabaptist theologians who remain true to the tradition's pacifist roots rightfully cry ‘foul’ in response to Aquinas’ theory. If Jesus of Nazareth fully reveals the character of God as indicated in John 14:7 with the words, ‘if you have seen me, you have seen the Father’, theories of atonement which depict God as condoning or requiring violence do not harmonise with the life and teachings of the man Christians call the Prince of Peace, especially if that violence pertains to the redemption of a loving God's good creation. As a result, those who oppose the implicit divine violence embedded in Aquinas’ satisfaction theory of atonement may opt to disengage with him, to expel him completely from the conversation. Yet I suggest that non-violent atonement theologians pause and rethink their indictment of the angelic doctor. Satisfaction remains the prevalent theme surrounding Aquinas’ atonement motif, but it is not by any means the only image he brings to bear on the topic. In fact, throughout his ruminations on the passion of Christ, St Thomas focuses explicitly on the unfathomable, extravagant and immeasurable divine love as the primary motivation for God's desire and subsequent actions to redeem and restore a sinful humanity. I suggest that, given Aquinas’ emphasis on divine love, Anabaptist theologians may well discover a satisfying interlocutor for further theological conversation which carries significant implications for the life of the church. Indeed, scholastic savants such as Thomas Aquinas still do warrant a place at the communal table.
Infant and Child Burial Rites in Roman Britain: a Study from East Yorkshire
Authors: Millett Martin , Gowland Rebecca 
Published: April 2015

AbstractThe discovery of infant burials on excavated domestic sites in Roman Britain is fairly common but in the past these burials have often been dismissed as a product of unceremonious disposal. There is a growing literature which considers the phenomenon, but it has been dominated by debates around the suggestion that these burials provide evidence for infanticide, with a focus on the osteological evidence for and against this hypothesis. There has been less systematic consideration of the archaeological context of such burials. In this paper we examine the excavated evidence of two large groups of such burials from sites in East Yorkshire which demonstrate that the burial of neonatal infants followed a careful age-specific funerary rite. We suggest that this conclusion further undermines the widespread assumption that infants were disposed of without ceremony and as a result of infanticide.
Stability of L1 contractions
Authors: BARREIRA LUIS , VALLS CLAUDIA 
Published: April 2015

AbstractThe notion of an exponential contraction is only one among many possible rates of contraction of a nonautonomous system, while for an autonomous system all contractions are exponential. We consider the notion of an L1 contraction that includes exponential contractions as a very particular case and that is naturally adapted to the variation-of-parameters formula. Both for discrete and continuous time, we show that under very general assumptions the notion of an L1 contraction persists under sufficiently small linear and nonlinear perturbations, also maintaining the type of stability. As a natural development, we establish a version of the Grobman–Hartman theorem for nonlinear perturbations of an L1 contraction.

SUMMARYThis study aims to describe in detail the temporal dynamics ofE. coliO157 shedding and risk factors for shedding in a grass-fed beef herd. During a 9-month period, 23 beef cows were sampled twice a week (58 sampling points) andE. coliO157 was enumerated from faecal samples. Isolates were screened by PCR for presence ofrfbE,stx1andstx2. The prevalence per sampling day ranged from 0% to 57%. This study demonstrates that many members of the herd were concurrently sheddingE. coliO157. Occurrence of rainfall (P< 0·01), feeding silage (P< 0·01) and lactating (P< 0·01) were found to be predictors of shedding. Moving cattle to a new paddock had a negative effect on shedding. This approach, based on short-interval sampling, confirms the known variability of shedding within a herd and highlights that high shedding events are rare.

Published: April 2015

SUMMARYGroup B streptococcus (GBS) is an increasing cause of disease in adults. We present long-term trends in incidence of overall infections and identify characteristics of patients with GBS cellulitis, bone and joint infections. Active, population-based surveillance was conducted from 1995–2012 in three California counties and the data were analysed retrospectively. All cases had isolation of GBS from a normally sterile site. Cases of cellulitis were classified based on clinical diagnosis. GBS bone or joint infection was defined as isolation of GBS from a bone or joint or a diagnosis of osteomyelitis or septic arthritis. Medical charts were reviewed for demographic and clinical information. There were 3917 cases of GBS; the incidence of disease increased from 5·8 to 8·3 cases/100 000 persons (P < 0·001) from 1995 to 2012. In adults aged ⩾40 years, the overall incidence of GBS increased from 8·5 to 14·2 cases/100 000 (P < 0·001) persons during the study period. The incidence of cellulitis increased from 1·6 to 3·8 cases/100 000 (P < 0·001), bone infection increased from 0·7 to 2·6 cases/100 000 (P < 0·001), and the incidence of joint infection remained approximately constant at an average rate of 1·0 case/100 000. The highest incidence rates were observed in men, persons aged ⩾80 years, non-Hispanic blacks and Hispanics. Diabetes was the most common underlying condition (51·2% cellulitis cases, 76·3% bone infections, 29·8% joint infections).

SUMMARYAcute haemorrhagic conjunctivitis outbreaks are often attributed to viral infection. In 2014, an unprecedented nationwide outbreak of infectious conjunctivitis occurred in Thailand, which affected >300 000 individuals over 3 months. To identify and characterize the virus responsible for the epidemic, eye swab specimens from 119 patients were randomly collected from five different provinces. Conserved regions in the enteroviral 5′-UTR and adenovirus hexon gene were analysed. Enterovirus was identified in 71·43% (85/119) of the samples, while no adenovirus was detected. From enterovirus-positive samples, the coxsackievirus A24 variant (70·59%, 84/119) and echovirus (0·84%, 1/119) were identified. Additional sequencing of full-length VP1 and 3C genes and subsequent phylogenetic analysis revealed that these clinical isolates form a new lineage cluster related to genotype IV-C5. In summary, the coxsackievirus A24 variant was identified as an aetiological agent for the recent acute haemorrhagic conjunctivitis outbreak in Thailand.
From Amelia to Calista and Beyond: Sentimental Heroines, ‘Fallen’ Women and Handel’s Oratorio Revisions for Susanna Cibber
Authors: Lee Jonathan Rhodes 
Published: April 2015

AbstractThe history of singer and famed tragedienne Susanna Cibber (1714–66) demonstrates the influences of the British theatre and the culture of sentiment on Handel’s oratorios. Throughout Cibber’s long career, audiences lauded the ‘natural’ qualities of her performances, conflating her onstage and offstage identities as both deeply moving and holding great potential for moral instruction. In the late 1730s and early 1740s this presumed symbiosis was challenged by a highly publicised sex scandal that had profound effects on Cibber’s roles in the spoken theatre. At the same moment, Handel began crafting parts for Cibber inMessiah,Samson,HerculesandBelshazzarin ways that showed awareness of the new complexity of her image. This article both illustrates the nature of Cibber’s evolving public identity and explains Handel’s revisions of pre-existing parts for her. It shows that Handel recognised the challenges of Cibber’s troubled public image and continued to highlight her greatest skills, setting her the task of harnessing the power of sympathy, drawing audiences in by appealing to them as fellow men and women of sensibility.
