English language support: A dialogical multi-literacies approach to teaching students from CALD backgrounds
Authors: Berniz Kate , Miller Andrew 
Published: February 2018

Abstract
Students in Western university contexts require multiple literacies, numeracies, and critical capacities to succeed. Participation requires a blend of English language capacity, cultural knowhow, and cognisance of the often-hidden racialized assumptions and dispositions underpinning literate performance. Students from Culturally and Linguistically Diverse (CALD) backgrounds transitioning to Western university settings from local and international contexts often find themselves floundering in this complex sociocultural web. Many students struggle with the English language preferences of their institutions despite meeting International English Language Testing System (IELTS) requirements. Once enrolled, students from CALD backgrounds need to navigate the linguistic, semiotic, and cultural landscape of the university, both physically and virtually, to enter the discourses and practices of their chosen disciplines. Universities cannot afford to allow students to ‘sink or swim’ or struggle through with non-specialist or ad-hoc support. In response to a clear need for explicit and ongoing English language support for students from CALD backgrounds, the Student Learning Centre (SLC) at Flinders University in South Australia created the English Language Support Program (ELSP). The ELSP sets out to overcome prescriptive and assimilationist approaches to language support by adopting an eclectic blend of learner-centred, critical-creative, and multi-literacies approaches to learning and teaching. Rather than concentrate on skills and/or language appropriateness, the ELSP broadens its reach by unpacking the mechanics and machinations of university study through an intensive—and transgressive—multi-module program. This paper outlines the theoretical and pedagogical challenges of implementing the ELSP.
Employing a results-based algorithm to reduce laboratory utilization in ACTH stimulation testing
Authors: McDonough Ryan J. , Alba Patria , Dileepan Kavitha , Cernich Joseph T. 
Published: February 2018

Abstract

Background:
The High Dose Adrenocorticotropic Hormone (ACTH) Stimulation Test is the gold standard to diagnose adrenal insufficiency. Normal adrenal function is defined as a peak cortisol response to pharmacologic stimulation with cosyntropin of ≥18 μg/dL. Our practice was to obtain cortisol levels at 0, 30 and 60 min after cosyntropin administration. Once a value of ≥18 μg/dL has been obtained, adrenal insufficiency is ruled out and there is little diagnostic utility in subsequent stimulated levels.

Methods:
We aimed to decrease laboratory utilization by developing a results-based algorithm in the electronic medical record (EMR). Cortisol levels were analyzed on the 0 and 60 min samples; then an EMR discern rule automatically generated an order to analyze the 30-min sample if the 60-min cortisol level was subnormal.

Results:
Exclusion of adrenal insufficiency was excluded using one stimulated cortisol level in 8% prior to algorithm development. After several plan-do-study-act cycles, 99% of normal tests were performed using only one stimulated cortisol level.

Conclusions:
This laboratory-based algorithm resulted in reduced laboratory utilization, and aligned our practice to recommendations of the Pediatric Endocrine Society. Similar algorithms could be created for other dynamic tests to reduce unnecessary laboratory utilization.

Authors: Zhang Xuping , Chen Qiyu , Li Yongxiang 
Published: February 2018

Abstract
This paper is devoted to study the existence and regularity of mild solutions in some interpolation spaces for a class of functional partial differential equations with nonlocal initial conditions. The linear part is assumed to be a sectorial operator in Banach space X. The fractional power theory and α-norm are used to discuss the problem so that the obtained results can be applied to equations with terms involving spatial derivatives. Moreover, we present an example to illustrate the application of main results.

AbstractA distributed feedback dual-gate graphene-channel field-effect transistor (DFB-DG-GFET) was fabricated as a current-injection terahertz (THz) light-emitting laser transistor. We observed a broadband emission in a 1–7.6-THz range with a maximum radiation power of ~10 μW as well as a single-mode emission at 5.2 THz with a radiation power of ~0.1 μW both at 100 K when the carrier injection stays between the lower cutoff and upper cutoff threshold levels. The device also exhibited peculiar nonlinear threshold-like behavior with respect to the current-injection level. The LED-like broadband emission is interpreted as an amplified spontaneous THz emission being transcended to a single-mode lasing. Design constraints on waveguide structures for better THz photon field confinement with higher gain overlapping as well as DFB cavity structures with higher Q factors are also addressed towards intense, single-mode continuous wave THz lasing at room temperature.
CT guided neurolytic blockade of the coeliac plexus in patients with advanced and intractably painful pancreatic cancer
Authors: Rosland Jan Henrik , Geitung Jonn Terje 
Published: February 2018

Abstract

Background and aims:
Pain caused by infiltrating pancreatic cancer is complex in nature and may therefore be difficult to treat. In addition to conventional analgesics, neurolytic blockade of the coeliac plexus is often recommended. However, different techniques are advocated, and procedures vary, and the results may therefore be difficult to compare. Therefore strong evidence for the effect of this treatment is still lacking, and more studies are encouraged. Our aim was to describe our technique and procedures using a Computer Tomograph (CT) guided procedure with a dorsal approach and present the results.

Methods:
The procedures were performed in collaboration between a radiologist and an anaesthesiologist. All patients had advanced pancreatic cancer. The patients were placed in prone position on pillows, awake and monitored. Optimal placement of injection needles was guided by CT, and the radiologist injected a small dose of contrast as a control. When optimal needle position, the anaesthesiologist took over and completed the procedure. At first 40 mg methylprednisolone was injected to prevent inflammation. Thereafter a mixture of 99% ethanol diluted to 50% by ropivacaine 7.5 mg/mL to a total amount of 20–30 mL per needle was slowly injected. Repeated aspiration was performed during injection to avoid intravasal injection. Pain treatment and pain score was recorded and compared before and after the treatment.

Results:
Eleven procedures in 10 patients were performed. Age 49–75, mean 59 years. Median rest life time was 36 days (11–140). Significant reduction of analgesics was observed 1 week after the procedure, and most patients also reported reduction of pain. No serious side effects were observed.

Conclusions:
CT guided neurolytic celiac plexus blockade is a safe and effective treatment for intractable pain caused by advanced pancreatic cancer. Not all patients experience a significant effect, but the side effects are minor, and the procedure should therefore be offered patients experiencing intractable cancer related pain.
Ein Pionier der Hospiz-Bewegung in Deutschland: P. Reinhold Iblacker SJ (1930–1996)
Authors: Funiok Rüdiger 
Published: February 2018

Zusammenfassung
Das Konzept des modernen Hospizes (Cicely Saunders, London) wurde in Deutschland 1971 durch zwei erfolgreiche Fernsehfilme bekannt gemacht. Autor war der Jesuitenpater Reinhold Iblacker, der bis 1984 noch ca. 100 weitere wertorientierte Medienbeiträge produzierte. Als er aus gesundheitlichen Gründen diese breite Medienarbeit beenden musste, begann die zweite Phase seiner Pionierarbeit für Hospize und Palliative Care. In der Öffentlichkeit focht er den wichtigen semantischen Kampf gegen den belasteten Begriff „Sterbeklinik“ à la Dr. Hackethal aus. Angeregt durch die Initiativen in Großbritannien, USA und Kanada, wurde Palliative Care auch unter Ärzten und Pflegekräften bekannt. „Pflegen bis zuletzt“ bedeutete für sie ein Umdenken, zumindest ein Weiterdenken, was nach dem Ende von Therapien noch möglich ist, und damit eine Erweiterung ihrer beruflichen Kompetenz. Am Beispiel des Christophorus Hospiz Vereins in München wird deutlich gemacht, wie P. Iblacker weiter für diese Idee publizistisch tätig war. Schließlich beteiligte er sich auch an der konkreten Vereinsarbeit – unterstützt von zahlreichen Ärztinnen und Ärzten und seinem großen Freundeskreis. Die Verbreitung der Hospizidee in Deutschland bleibt mit seinem Namen und seiner vielgestaltigen Pionierleistung verbunden.
Temperature dependent optical properties of red emitting Na3GaF6:Mn4+as a color converter for warm white LEDs
Authors: Böhnisch David , Jansen Thomas , Pöttgen Rainer , Jüstel Thomas 
Published: February 2018

AbstractThis work presents and disentangles the temperature dependent optical properties of the red-emitting phosphor Na3GaF6:Mn4+. Moreover, crystal field and Racah parameters were investigated. It was proven that the material is suitable for the application in warm white LEDs due to its high quantum yield of about 83%, little thermal quenching of the photoluminescence up to 410 K, high lumen equivalent of about 220 lm/W, and strong absorption at 450 nm. In addition, different DFT approaches were used to investigate its band structure. The calculated data were compared to those obtained experimentally. Red phosphor spectra were calculated to evaluate the suitability of red line-emitting phosphors for the application in warm white emitting pcLEDs. Finally, warm white emitting LEDs comprising Na3GaF6:Mn4+were constructed in order to show the potential of Na3GaF6:Mn4+serving as a red component in phosphor blends for future warm white pcLEDs.

Published: February 2018

Abstract
This paper analyses the dynamics of soliton propagation through optical fibres for the perturbed nonlinear Schrödinger equation with Kerr law and non-Kerr law nonlinearity. Several integration schemes are used to construct solitons to the model. The two forms of nonlinearity that are studied in detail are power law and dual power law, while Kerr law and parabolic law emerge as special cases to these two laws.
Enhancement of the Fluorescence Quantum Yield of Thiol-Stabilized CdTe Quantum Dots Through Surface Passivation with Sodium Chloride and Bicarbonate

Published: February 2018

Abstract
Colloidal quantum dots (QDs) have potential for several applications, e.g. as novel light sources; as photoluminescent probes; and for solar energy conversion devices, but their sensitivity towards their environmental surroundings, and the presence of surface defects may still degrade their emission properties. Herein, we present a post-synthetic treatment of CdTe QDs stabilized by mixed thiol ligands using chloride and bicarbonate ions to achieve near-complete surface passivation, resulting in a two-fold increase of the photoluminescence quantum yield (PL QY) and significant suppression of non-radiative recombination. Time-resolved PL measurements reveal fluorescence lifetime and PL QY trends did not both track identically; in the most favorable cases a suppression of non-radiative recombination and a slight increase in the radiative recombination rates after the salt treatment took place. The optimized conditions demonstrated here are proven to work for different sizes of CdTe QDs, and also show a dependence on the composition of the mixed ligand systems used.

Abstract
Estibaliz, R, Fabio, N, Rodrigo, RC, Daniel, C, Josune, RN, and Javier Y. Differences in physical performance according to the competitive level in amateur handball players. J Strength Cond Res 34(7): 2048–2054, 2020—The aim of this study was to compare physical performance in amateur handball players of 2 different competitive levels. Thirty-four senior handball players were divided into 2 groups according to their competitive level (regional category: REG or national category: NAC). Although no significant differences were found between groups in any of the horizontal jump (HJ) or vertical jump (VJ) variables (p > 0.05), NAC players obtained a better performance in the repeated sprint ability (RSA) test (RSABest [the best attempt] and RSATT [the total time in the total of sprints] in 15 m and 30 m), in change of direction ability (CODA) and in the Yo-Yo Intermittent Recovery Test Level 1 (YYIR1) test (p < 0.01, effect size = −1.32 to 1.75, large). A significant association was observed between the body mass index (BMI) and the HJ or VJ capacity (r = −0.35 to −0.55, p < 0.01), the RSA15mBest and RSA30mBest (r = 0.41 to 0.59, p < 0.01), and YYIR1 distance (r = −0.54, p ≤ 0.05), and a also between the performance in the HJ or the VJ and the RSA15mBest and RSA30mBest, the CODA and the YYIR1, and between the RSA30mBest and the YYIR1 (r = −0.54, p ≤ 0.05). Specific strength and conditioning programs should aim toward improving RSA, CODA, and YYIR1, as these abilities may be needed at higher levels of competition. The programs also should aim toward improved HJ and VJ abilities, given their association with RSA, CODA, and YYIR1 performance. Moreover, maintaining an adequate BMI may aid players to sustain greater physical performance levels.
Vertical and Horizontal Asymmetries Are Related to Slower Sprinting and Jump Performance in Elite Youth Female Soccer Players

Abstract
Bishop, C, Read, P, McCubbine, J, and Turner, A. Vertical and horizontal asymmetries are related to slower sprinting and jump performance in elite youth female soccer players. J Strength Cond Res 35(1): 56–63, 2021—Interlimb asymmetries have been shown to be greater during vertical jumping compared with horizontal jumping. Notable interlimb differences have also been established at an early age in male youth soccer players. Furthermore, given the multiplanar nature of soccer, establishing between-limb differences from multiple jump tests is warranted. At present, a paucity of data exists regarding asymmetries in youth female soccer players and their effects on physical performance. The aims of this study were to quantify interlimb asymmetries from unilateral jump tests and examine their effects on speed and jump performance. Nineteen elite youth female soccer players performed a single-leg countermovement jump (SLCMJ), single, triple, and crossover hops for distance, and a 20-m sprint test. Test reliability was good to excellent (intraclass correlation coefficient = 0.81–0.99) and variability acceptable (coefficient of variation = 1.74–5.42%). A 1-way analysis of variance highlighted larger asymmetries from the SLCMJ compared with all other jump tests (p < 0.05). Pearson's correlations portrayed significant relationships between vertical asymmetries from the SLCMJ and slower sprint times (r = 0.49–0.59). Significant negative relationships were also found between horizontal asymmetries during the triple hop test and horizontal jump performance (r = −0.47 to −0.58) and vertical asymmetries during the SLCMJ and vertical jump performance (r = −0.47 to −0.53). The results from this study highlight that the SLCMJ seems to be the most appropriate jump test for identifying between-limb differences with values ∼12% showing negative associations with sprint times. Furthermore, larger asymmetries are associated with reduced jump performance and would appear to be direction specific. Practitioners can use this information as normative data to be mindful of when quantifying interlimb asymmetries and assessing their potential impact on physical performance in youth female soccer players.

AbstractCiccone, AB, Deckert, JA, Schlabs, CR, Tilden, MJ, Herda, TJ, Gallagher, PM, and Weir, JP. Transcranial direct current stimulation of the temporal lobe does not affect high-intensity work capacity.J Strength Cond Res33(8): 2074–2086, 2019—Stimulation of the left insular cortex may affect heart rate variability (HRV) and exercise effort perception. These studies investigated the effects transcranial direct current stimulation (tDCS) and electrode orientation on HRV and repeated maximal knee extensions. In study 1, after sham stimulation, anodal left temporal lobe stimulation, or anodal right temporal lobe stimulation, 10 male and 10 female subjects (age = 21.0 ± 1.5 years) completed 50 maximum isokinetic extensions at 180°·s−1. There was a significant effect of stimulation condition on HRV for only 1 (SD2;p= 0.037; η2= 0.159) of 5 HRV metrics. There was no significant effect on isokinetic fatigue percent or isokinetic work (allp≥ 0.278; all η2≤.065). It has been proposed that placing the cathode electrode on the shoulder may differentially affect tDCS. Therefore, in study 2, the effects of electrode orientation on tDCS-induced changes in HRV was assessed in 10 healthy females and 8 healthy males (21.6 ± 2.5 years) who completed cephalic, extracephalic, and sham trials. In the cephalic montage, the anode was placed over the left temporal lobe and the cathode was placed over right prefrontal cortex. In the extracephalic montage, the cathode was placed on the shoulder on the same side of the body as the anode. Neither cephalic nor extracephalic montages affected HRV (allp≥ 0.152; all η2≤.105). These data suggest that anodal tDCS of the insular cortex has little effect on HRV, and does not improve high-intensity exercise performance in the current population. Therefore, anodal tDCS applied over the left temporal lobe is not recommended for high-intensity performance enhancement.
The End of a 60-year Riddle: Identification and Genomic Characterization of an Iridovirus, the Causative Agent of White Fat Cell Disease in Zooplankton

Published: February 2018

Abstract
The planktonic freshwater crustacean of the genus Daphnia are a model system for biomedical research and, in particular, invertebrate-parasite interactions. Up until now, no virus has been characterized for this system. Here we report the discovery of an iridovirus as the causative agent of White Fat Cell Disease (WFCD) in Daphnia. WFCD is a highly virulent disease of Daphnia that can easily be cultured under laboratory conditions. Although it has been studied from sites across Eurasia for more than 60 years, its causative agent had not been described, nor had an iridovirus been connected to WFCD before now. Here we find that an iridovirus—the Daphnia iridescent virus 1 (DIV-1)—is the causative agent of WFCD. DIV-1 has a genome sequence of about 288 kbp, with 39% G+C content and encodes 367 predicted open reading frames. DIV-1 clusters together with other invertebrate iridoviruses but has by far the largest genome among all sequenced iridoviruses. Comparative genomics reveal that DIV-1 has apparently recently lost a substantial number of unique genes but has also gained genes by horizontal gene transfer from its crustacean host. DIV-1 represents the first invertebrate iridovirus that encodes proteins to purportedly cap RNA, and it contains unique genes for a DnaJ-like protein, a membrane glycoprotein and protein of the immunoglobulin superfamily, which may mediate host–pathogen interactions and pathogenicity. Our findings end a 60-year search for the causative agent of WFCD and add to our knowledge of iridovirus genomics and invertebrate–virus interactions.
A Genetic Screen Identifies PRP18a, a Putative Second Step Splicing Factor Important for Alternative Splicing and a Normal Phenotype inArabidopsis thaliana

Published: February 2018

AbstractSplicing of pre-mRNA involves two consecutive trans-esterification steps that take place in the spliceosome, a large dynamic ribonucleoprotein complex situated in the nucleus. In addition to core spliceosomal proteins, each catalytic step requires step-specific factors. Although the Arabidopsis thaliana genome encodes around 430 predicted splicing factors, functional information about these proteins is limited. In a forward genetic screen based on an alternatively-spliced GFP reporter gene in Arabidopsis thaliana, we identified a mutant impaired in putative step II factor PRP18a, which has not yet been investigated for its role in pre-mRNA splicing in plants. Step II entails cleavage at the 3′ splice site accompanied by ligation of the 5′ and 3′ exons and intron removal. In the prp18 mutant, splicing of a U2-type intron with non-canonical AT-AC splice sites in GFP pre-mRNA is reduced while splicing of a canonical GT-AG intron is enhanced, resulting in decreased levels of translatable GFP mRNA and GFP protein. These findings suggest that wild-type PRP18a may in some cases promote splicing at weak, non-canonical splice sites. Analysis of genome-wide changes in alternative splicing in the prp18a mutant identified numerous cases of intron retention and a preponderance of altered 3′ splice sites, suggesting an influence of PRP18a on 3′ splice site selection. The prp18a mutant featured short roots on synthetic medium and small siliques, illustrating that wild-type PRP18a function is needed for a normal phenotype. Our study expands knowledge of plant splicing factors and provides foundational information and resources for further functional studies of PRP18 proteins in plants.
