Teachers’ professional development through teachers’ professional activities
Authors: Sharma Payal , Pandher Jagwinder Singh 
Published: October 2018

Purpose
This study aims to identify various teachers’ professional activities (TPAs) and classify these TPAs according to their relative importance for the professional development of teachers.

Design/methodology/approach
The systematic review of the literature had been conducted to identify various TPAs in the institutions. Later, an empirical research had been conducted through confirmatory factor analysis using AMOS 20.0 to classify these TPAs according to their relative importance using the natural gap in standardized beta (β) values. In total, 96 administrators of 35 technical institutions of Punjab (India) offering engineering and management programs and 93 veteran educational experts had responded in a field survey.

Findings
The results of the study identified eight TPAs and further revealed that “regular self-assessment,” “adopting a creative problem-solving approach” and “developing deep commitment to make the difference” qualify among the “most important” activities for the professional enhancement of the faculty.

Originality/value
The study highlights different TPAs that they must establish, raise, promote, encourage and organize for their development. The study further classifies different activities according to their relative importance. The institute can evaluate their resources, budgets and efforts according to the relative importance of such activities. The classification of TPAs would help faculty to increase their efficacy.
Non-linear fracture in bi-directional graded shafts in torsion
Authors: Rizov Victor 
Published: October 2018

Purpose
The purpose of this paper is to develop an analysis of longitudinal fracture behaviour of a functionally graded non-linear-elastic circular shaft loaded in torsion. It is assumed that the material is functionally graded in both radial and longitudinal directions of the shaft (i.e. the material is bi-directional functionally graded).

Design/methodology/approach
The Ramberg–Osgood stress-strain relation is used to describe the non-linear mechanical behaviour of the functionally graded material. The fracture is studied in terms of the strain energy release rate by analysing the balance of the energy. The strain energy release rate is obtained also by differentiating of the complementary strain energy with respect to the crack area for verification.

Findings
Parametric studies are carried out in order to evaluate the influence of material gradients in radial and longitudinal directions, the crack location in radial direction and the crack length on the fracture behaviour of the shaft. It is found that by using appropriate gradients in radial and longitudinal directions, one can tailor the variations of material properties in order to improve the fracture performance of the non-linear-elastic circular shafts to the externally applied torsion moments.

Originality/value
A longitudinal cylindrical crack in a bi-directional functionally graded non-linear-elastic circular shaft loaded in torsion is analysed by using the Ramberg–Osgood stress-strain relation.
Dual judgment processing in feedback: opening Pandora’s box
Authors: De Stobbeleir Katleen , Desmet Lien 
Published: October 2018

Purpose
In this commentary, the authors follow DeNisi and Sockbeson’s suggestions to reintegrate the organizational feedback and feedback-seeking literatures. They build on and extend their theorizing by suggesting a framework of simultaneous dual judgment processing in both feedback-seeking and organizational feedback interventions..

Design/methodology/approach
In the model, evaluation salience plays a role in how performance information is stored (i.e. as online judgments or loose memories), and rater motivation will determine to what extent the rater will deliberately use the stored information to give feedback.

Findings
The authors clarify some of the implications of the model for the accuracy of the feedback given, as well as how the cognitive methods that are used can be one of the explaining mechanisms in the link between feedback and performance.

Originality/value
This dual judgment processing approach accounts for the true complexity of the process of organizational feedback that has been largely ignored in past research.

Mechanical reliability of short carbon fiber reinforced ABS produced via vibration assisted fused deposition modeling
Authors: Keleş Özgür , Anderson Eric H. , Huynh Jimmy 
Published: October 2018

Purpose
Mechanical reliability (variations in mechanical properties) of fused deposition modeled (FDMed) short-fiber-reinforced composites are unknown, which limits wider and safer use of these composites. Accordingly, this paper aims to investigate the mechanical reliability of FDMed model material short-carbon-fiber-reinforced acrylonitrile butadiene styrene (SCFR-ABS). A new vibration-assisted FDM (VA-FDM) process was used to reduce porosity.

Design/methodology/approach
Tensile tests were performed on FDMed SCFR-ABS produced with and without vibrations. Weibull analysis was performed to quantify the variation in fracture strength, tensile strength, strain at break and strain at tensile strength.

Findings
Introduction of vibrations to the extrusion head during FDM decreased the inter-bead porosity in SCFR-ABS and thus improved elastic modulus, toughness, fracture strength, tensile strength and strain at break. Weibull modulus of fracture strength increased from 25 to 57 with vibrations.

Practical implications
The reported Weibull analysis offers a practical design guideline to predict failure rates at specific service stresses.

Originality/value
A detailed Weibull analysis of the variations in the mechanical properties of FDMed SCFR-ABS was performed for the first time. A new vibration-assisted FDM process was reported to reduce inter-bead porosity in FDMed composites.
Seedling growth of savanna tree species from three continents under grass competition and nutrient limitation in a greenhouse experiment

Published: October 2018

Abstract

Changes in savanna tree species composition, both within landscapes and across climatic gradients, suggest that species differ in their ability to utilize resources and cope with grass competition. Linking trait variation among species to their relative performance under resource limitation and competition treatments could provide mechanistic understanding of species’ turnover across environmental gradients in savannas. We investigated how tree species differ in response to competition from grasses and nutrient supply, and whether these responses can be related to plant traits. As humid savannas are often associated with low fertility, species of humid savannas may grow more efficiently under nutrient suppression than species from semi‐arid savannas. In heterogeneous grass swards, fast‐growing, resource‐wasteful species may be found in low grass biomass patches and slow‐growing, conservative species in high biomass patches.

We compared seedlings of 40 tree species sampled from humid and semi‐arid savannas of three continents (Africa, Australia, South America) with and without grass competition and with high and low nutrient supply. We measured traits related to soil resource capture, light capture, and growth, and tested whether these traits were related to performance under the four treatments.

All tree species were suppressed by grass competition and most by nutrient limitation. Only species from humid savannas in Australia grew better under nutrient limitation than their semi‐arid counterparts. Deciduous species from semi‐arid climates were more negatively impacted by grass competition than deciduous species from humid climates whereas the reverse pattern was observed among evergreen species. Faster growing species were more severely suppressed by grass competition and low nutrients than slower growing species. Traits associated with soil resource capture and seed mass supported growth under grass competition and nutrient limitation, but the traits differed by continent and by leaf habit.

Synthesis. We found limited evidence that tree seedlings from humid savannas grow better under nutrient limitation than species of semi‐arid savannas. We confirmed that fast‐growing species may be advantaged in low grass biomass patches and conservative species in high biomass patches. Traits that improved performance under grass competition differed by continent, which may relate to differences in leaf habit and constraints on seed size.
From Interdependency to Co‐dependency: Changing Relations in UK and Devolved Governments Post‐Brexit
Authors: Mitchell James 
Published: October 2018

AbstractThe Scottish and European Questions have become intertwined over time. A European turn in Scottish politics became evident from the late 1980s when public opinion moved in favour of the European Communities/Union. The Scottish National Party (SNP) became a leading advocate of EC/EU membership with Europe's four freedoms allowing it to dismiss accusations of separatism. Scotland voted in favour of Remain in the Brexit referendum, adding to existing tensions in UK‐Scottish government relations. The institutions and procedures of intergovernmental relations which were designed to cope with tensions are being tested as never before under devolution. The assertion of UK power in these relations has undermined claims made by David Cameron to pursue a ‘respect agenda’ and commitments made immediately after the independence referendum. But while this evidence of divergent views on such a significant matter creates potential challenges for the UK union, it also creates new challenges for the SNP. The prospect of a hard Brexit raises the issue of separatism once more, with a choice of either remaining in the EU but separate from the rest of the UK (rUK), or remain in a separatist UK.

ObjectiveTo compare hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) versus total laparoscopic hysterectomy (TLH) as a day‐care procedure.DesignParallel group, 1:1 randomised single‐centre single‐blinded trial, designed as a non‐inferiority study with a margin of 15%.SettingBelgian teaching hospital.PopulationWomen aged 18–70 years scheduled to undergo hysterectomy for benign indications.MethodsRandomisation to TLH (control group) or vNOTES (experimental group). Stratification according to uterine volume. Blinding of participants and outcome assessors.Main outcome measuresThe primary outcome was hysterectomy by the allocated technique. We measured the proportion of women leaving within 12 hours after hysterectomy and the length of hospital stay as secondary outcomes.ResultsWe randomly assigned 70 women to vNOTES (n = 35) or TLH (n = 35). The primary endpoint was always reached in both groups: there were no conversions. We performed a sensitivity analysis for the primary outcome, assuming one conversion in the vNOTES group and no conversions in the TLH group: the one‐sided 95% upper limit for the differences in proportions of conversion was estimated as 7.5%, which is below the predefined non‐inferiority margin. More women left the hospital within 12 hours after surgery after vNOTES: 77 versus 43%, difference 34% (95% CI 13–56%), P = 0.007. The hospital stay was shorter after vNOTES: 0.8 versus 1.3 days, mean difference −0.5 days, (95% CI −0.98 to −0.02), P = 0.004.ConclusionsvNOTES is non‐inferior to TLH for successfully performing hysterectomy without conversion. Compared with TLH, vNOTES may allow more women to be treated in a day‐care setting.Tweetable abstractRCT: vNOTES is just as good as laparoscopy for successful hysterectomy without conversion but allows more day‐care surgery.

Published: October 2018

AbstractThis study involves an investigation of the probiotic properties of lactic acid bacteria isolated from Kimchi, and their potential applications in chocolate. Lactobacillus plantarum—LRCC5193 (LP‐LRCC5193) demonstrated a significantly higher degree of heat, acid, and bile acid tolerance compared to other Kimchi isolates. The intestinal adhesion assay also revealed that 84.2 log percentage of LP‐LRCC5193 adhered to the Caco‐2 cells after 2 h of incubation. Furthermore, the lyophilized LP‐LRCC5193 maintained 92.9 log percentage and 97.2 log percentage survival rate within artificial stomach juice (pH 2.5, pepsin 0.04%) and artificial intestinal juice (oxgall 0.5%, trypsin 0.04%, and pancreatin 0.04%), respectively. Meanwhile, we also found that lyophilized LP‐LRCC5193 incorporated in chocolate exhibited significantly higher survivability than lyophilized LP‐LRCC5193 in both artificial gastric and intestinal juice under 1 to 3 hr incubation, where the survivability was within the range of 96.3 to 98.5 log percentage, and 98.8 to 98.9 log percentage, respectively. A 6‐month storage test further revealed that LP‐LRCC5193 demonstrated higher stability than the lyophilized LP‐LRCC5103 in 3 different temperature ranges, where the final survival rates were 97.2 log percentage (20 °C), 89.2 log percentage (33 °C), and 94.4 log percentage (15 to 30 °C/wk). Altogether, our data suggest that chocolate can be used as a tasty delivery vehicle for delivering putative probiotic strain, LP‐LRCC5193 to the gastrointestinal tract.Practical ApplicationLactobacillus plantarum LRCC5193 (LP‐LRCC5193) isolated from Kimchi demonstrated high stability under gastrointestinal environmental stresses and good adhesion to the intestinal epithelial cells in vitro. In addition, LP‐LRCC5193 containing chocolates remained highly stable after storage at room temperature for 6 months. Chocolate containing LP‐LRCC5193 can thus be considered a promising probiotic delivery system.
Body surface area as a novel risk factor for chylothorax complicating video‐assisted thoracoscopic surgery lobectomy for non‐small cell lung cancer
Authors: Li Shuangjiang , Wang Yan , Zhou Kun , Cheng Shan , Wu Yanming , Che Guowei 
Published: October 2018

BackgroundThe study was conducted to demonstrate the predictive value of body surface area (BSA) for chylothorax complicating video‐assisted thoracoscopic surgery (VATS) lobectomy for non‐small cell lung cancer (NSCLC).MethodsLarge‐scale retrospective analysis was conducted on the data of 1379 patients who underwent VATS lobectomy between January 2014 and October 2017 at our institution. Receiver operating characteristic analysis was conducted to determine a threshold BSA value for the prediction of chylothorax. This optimal BSA cutoff, other clinicopathological variables, and P < 0.15 were included into a multivariable logistic regression model to determine the risk factors for chylothorax.ResultsTwenty‐six patients (1.9%) developed postoperative chylothorax. The mean BSA in patients with chylothorax was significantly higher than in patients without (1.84 ± 0.14 vs. 1.73 ± 0.16 m2; P = 0.001). A BSA of 1.69 m2 was identified as the threshold value with maximum joint sensitivity (96.2%) and specificity (43.8%). Patients with BSA > 1.69 m2 had a significantly higher incidence of chylothorax (3.0% vs. 0.3%; P < 0.001) and a longer hospital stay (log rank P < 0.001) than patients with BSA ≤ 1.69 m2. Multivariable logistic regression analysis suggested that BSA > 1.69 m2 (odds ratio 7.35, 95% confidence interval 1.54–35.71; P = 0.013) was predictive of postoperative chylothorax.ConclusionsBSA can serve as a novel categorical predictor for chylothorax complicating VATS lobectomy for NSCLC. It may be more helpful to incorporate a BSA cutoff into routine risk stratification tools for lung cancer surgery.

Published: October 2018

BackgroundFew Internet smoking cessation programs specifically address the impact of alcohol use during a quit attempt, despite its common role in relapse. This study used topic modeling to describe the most prevalent topics about alcohol in an online smoking cessation community, the prevalence of negative sentiment expressed about alcohol use in the context of a quit attempt (i.e., alcohol should be limited or avoided during a quit attempt) within topics, and the degree to which topics differed by user social connectivity within the network.MethodsData were analyzed from posts from the online community of a larger Internet cessation program, spanning January 1, 2012 to May 31, 2015 and included records of 814,258 online posts. Posts containing alcohol‐related content (n = 7,199) were coded via supervised machine learning text classification to determine whether the post expressed negative sentiment about drinking in the context of a quit attempt. Correlated topic modeling (CTM) was used to identify a set of 10 topics of at least 1% prevalence based on the frequency of word occurrences among alcohol‐related posts; the distribution of negative sentiment and user social network connectivity was examined across the most salient topics.ResultsThree salient topics (with prevalence ≥10%) emerged from the CTM, with distinct themes of (i) cravings and temptations; (ii) parallel between nicotine addiction and alcoholism; and (iii) celebratory discussions of quit milestones including “virtual” alcohol use and toasts. Most topics skewed toward nonnegative sentiment about alcohol. The prevalence of each topic differed by users’ social connectivity in the network.ConclusionsFuture work should examine whether outcomes in Internet interventions are improved by tailoring social network content to match user characteristics, topics, and network behavior.
Paraskusella gen. nov., a new Afro‐Australian genus in the tribe Chironomini (Diptera: Chironomidae)
Authors: Cranston Peter S 
Published: October 2018

AbstractOne described species of Chironomidae, the African Paratendipes seydeli Freeman, 1957, and two newly described species from Australia are allocated to a new genus, Paraskusella gen. nov. Described from all life stages, Paraskusella donedwardi sp. nov. is restricted to south‐west Western Australia. Paraskusella bobhawkei sp. nov. is described from adult males and a female from northern Australia. Its possible immature stages are described as Paraskusella ‘K2’, a taxon with a wider northern to central and temperate distribution. The immature stages allow inference of proximity to the Afro‐Oriental‐Australian Skusella Freeman, 1961.
Predicting undetected glaucoma according to age and IOP: a prediction model developed from a primarily European‐derived population
Authors: Oskarsdottir Sigridur E. , Heijl Anders , Bengtsson Boel 
Published: October 2018

AbstractPurposeTo model prediction of undetected glaucoma in a predominantly white population, based on intraocular pressure (IOP) and subject age.MethodsIn 1992–1997, a population screening for glaucoma was performed at Malmö University Hospital where individuals between 55–79 years of age (n = 46 614) living in Malmö, were invited to a free eye health examination. Recently examined patients were not invited (n = 4117). IOP and age were recorded for all screened subjects. Subjects who screened positive were further examined to establish or reject a glaucoma diagnosis. We performed multiple regression analysis of the combined effect of age and IOP on the likelihood of undetected glaucoma.ResultsIn all, 32 918 subjects attended the screening (77.5% of invited), 22 218 women and 11 700 men, while 9579 refrained from participation. Glaucoma was diagnosed in 406 subjects. The proportion of subjects with glaucoma increased exponentially with increasing IOP and older age. Still, the majority of subjects with glaucoma (57%) had ≤IOP 21 mmHg. The predicted rate of undetected glaucoma was low, <5%, for subjects with IOP <25 mmHg, but rose rapidly with higher IOP, reaching 81% in the group with IOP >35 mmHg and age 75–79 years. The model fit well to the data (R2 = 0.97).ConclusionWe created a model estimating the combined effect of IOP and age on the likelihood of undetected glaucoma. The model may facilitate case‐finding in European‐derived populations. Despite the important impact of IOP on the risk of glaucoma, a large proportion of subjects with undetected glaucoma had IOP ≤ 21 mmHg.
