A study on relevance of second hand clothing retailing in Ethiopia
Authors: Khurana Karan , Tadesse Ruth 
Published: September 2019

Purpose
This paper aims to highlight the relevance of second-hand clothing (SHC) in the Ethiopian textile and apparel value chain by investigating its potential and establishing a connect to sustainability from a consumption point of view.

Design/methodology/approach
Primary and secondary methods of research were used in this research. Structured observational technique was used to identify the retailers in the city. In total, 70 retailers of SHC were identified and 15 big size retailers were interviewed with open end questions through judgment sampling method.

Findings
From the analysis of the field research and scientific literature, the authors strongly believe that SHC has an important space in the consumer retail segment of the country. This trade remains in the shadow but is sustaining livelihoods of citizens. The SHC trade provides an automatic balance to the future excessive consumption which is a result of mass production and hence should be encouraged further on various dimensions.

Originality/value
Existing literature exhibits statistics of the trade and impact in East African Community (EAC) missing out on Ethiopia as it is not a member of the EAC. Moreover a connection of SHC to sustainability established has never been established in the past for under-developing countries, and it is one of the critical factors in the success of used clothing and future of textile and apparel business. This research also provides channelized solutions to the business for smooth implementation of SHC in Ethiopia and other under-developing countries.

Authors: Kolb Tobias , Elahi Reza , Seeger Jan , Soris Mathews , Scheitler Christian , Hentschel Oliver , Tremel Jan , Schmidt Michael 
Published: September 2019

Purpose
The purpose of this paper is to analyse the signal dependency of the camera-based coaxial monitoring system QMMeltpool 3D (Concept Laser GmbH, Lichtenfels, Germany) for laser powder bed fusion (LPBF) under the variation of process parameters, position, direction and layer thickness to determine the capability of the system. Because such and similar monitoring systems are designed and presented for quality assurance in series production, it is important to present the dominant signal influences and limitations.

Design/methodology/approach
Hardware of the commercially available coaxial monitoring QMMeltpool 3D is used to investigate the thermal emission of the interaction zone during LPBF. The raw images of the camera are analysed by means of image processing to bypass the software of QMMeltpool 3D and to gain a high level of signal understanding. Laser power, scan speed, laser spot diameter and powder layer thickness were varied for single-melt tracks to determine the influence of a parameter variation on the measured sensory signals. The effects of the scan direction and position were also analysed in detail. The influence of surface roughness on the detected sensory signals was simulated by a machined substrate plate.

Findings
Parameter variations are confirmed to be detectable. Because of strong directional and positional dependencies of the melt-pool monitoring signal a calibration algorithm is necessary. A decreasing signal is detected for increasing layer thickness. Surface roughness is identified as a dominating factor with major influence on the melt-pool monitoring signal exceeding other process flaws.

Research limitations/implications
This work was performed with the hardware of a commercially available QMMeltpool 3D system of an LPBF machine M2 of the company Concept Laser GmbH. The results are relevant for all melt-pool monitoring research activities connected to LPBF, as well as for end users and serial production.

Originality/value
Surface roughness has not yet been revealed as being one of the most important origins for signal deviations in coaxial melt-pool monitoring. To the best of the authors’ knowledge, the direct comparison of influences because of parameters and environment has not been published to this extent. The detection, evaluation and remelting of surface roughness constitute a plausible workflow for closed-loop control in LPBF.

Environmental life cycle analysis of a fixed PV energy system and a two-axis sun tracking PV energy system in a low-energy house in Turkey
Authors: Aksoy Tırmıkçı Ceyda , Yavuz Cenk 
Published: September 2019

Purpose
The purpose of this paper is to propose a fixed PV energy system design and a sun tracking PV energy system design to meet the primitive energy demands of a typical house in Sakarya, Turkey with energy payback times (EPBT) and greenhouse payback times (GPBT) calculations.

Design/methodology/approach
The designs were developed based on the total solar radiation received on the surface of the PV modules. The EPBT and the GPBT of the designs were investigated by utilizing the current embodied energy data of the literature and annual energy output of the proposed systems. The monthly mean total solar radiation, the yearly total solar radiation and the annual energy output of the systems were calculated according to the results of previous studies of authors on 80-W prototypes of a fixed PV energy system tilted at the yearly optimum tilt angle of Sakarya and a two-axis sun tracking PV energy system.

Findings
The annual energy outputs of the fixed system and the tracking system were established to be 10.092 and 10.311 MJ, respectively. EPBT of the systems were estimated 15.347 years for the fixed system and 11.932 years for the tracking systems which were less than the lifespan of PV modules. The greenhouse gas emitted to produce and install the systems were estimated to be 6,899.342 kg for the fixed system and 5,040.097 kg for the tracking system. GPBT of the systems were calculated to be 5.203 and 2.658 years, respectively.

Originality/value
PV energy is clean without greenhouse gas emission during the operation. However, significant emissions occur in the life cycle of PV modules until the installation is completed. Therefore reducing the number of PV modules make great differences in the GPBT of PV energy systems. In this paper, comparisons between the GPBT results of the optimally tilted fixed system and tracking system were performed to discuss the best option by means of environmental concerns.

Published: September 2019

PurposeThe present study aims to investigate the dynamic relationship between international tourist receipts, economic growth, energy use and carbon dioxide (CO2) emissions in Pakistan over the period 1980-2016. Many researchers have investigated the link between tourism and CO2emissions, but there is no clear picture as the results are contradictory. This study is an attempt to compliment the literature related to tourism and environmental quality.Design/methodology/approachThe study adopted the autoregressive distributed lagged (ARDL) model to investigate the short- and long-run estimates simultaneously. The study further applied Granger causality to find out the direction of causalities. To arrive at long-run robust estimates, the study used dynamic ordinary least squares (DOLS) model.FindingsThe results found that tourist receipts have no significant impact on environmental quality, while growth and energy consumption are the main determinants of CO2emissions in Pakistan. The Granger causality test confirmed unidirectional causalities from GDP and energy consumption toward CO2emissions, while tourist receipts do not affect environmental quality. DOLS technique confirmed the long-run estimates of ARDL model.Research limitations/implicationsThe result of the study complements the literature by adding new evidence regarding the nexus of tourism and environment. Findings of the study are important for policymakers and regulatory bodies to place their focus on the development of tourism sector (services sector) rather than energy-intensive manufacturing activities to sustain the growth of the country in higher quartiles, as tourism receipts have no significant negative externalities toward environment, while energy use is one of the key determinants of environmental degradation.Originality/valueThis study used time series data over the period 1980-2016 for Pakistan to inspect the dynamic relationship between tourist receipts, economic growth, energy consumption and CO2emissions.

AbstractMaternal dyslipidaemia is a predisposing factor for arterial hypertension in male rat offspring at adulthood. This study was designed to investigate the short‐ and long‐term effects of maternal dyslipidaemia on blood pressure (BP) and baroreflex control in male rat offspring. Animals were obtained from mothers who received a dyslipidaemic (DLP, n = 7) or control (CTL, n = 7) diet during pregnancy and lactation. At 30 and 90 days of age, arterial pressure (AP), heart rate (HR) and baroreflex function were evaluated. In addition, spectral analysis of the systolic AP, diastolic AP, mean AP, HR, and spontaneous baroreflex were assessed. Data were expressed as mean ± SEM and Student's t‐test was used for comparison among groups, with statistical significance considered to be P < .05. At 30 days of age, male offspring had similar BP, HR and preserved baroreflex sensitivity. In addition, low frequency (LF) oscillation, high frequency (HF) oscillation and LF/HF ratio of AP and HR were similar in juvenile rats. At 90 days of age, male offspring from dyslipidaemic dams had augmented BP (P < .05) when compared to CTL group. Adult male rats from dyslipidaemic dams had a reduction in baroreflex control (P < .05) in comparison to CTL rats. The present study indicates that offspring from dams fed on a dyslipidaemic diet during pregnancy and lactation do not show alteration in blood pressure and baroreflex control in early life, but display a decline in baroreflex control and hypertension in adulthood.
The Review of the APS: Is gender really on anyone's agenda?
Authors: Colley Linda , Williamson Sue 
Published: September 2019

AbstractAs recently as 2016, the Australian Government stated its commitment to increasing gender equality in the Australian Public Service (APS) workforce. In May 2018, the Prime Minister announced a broad‐ranging Review of the APS, but gender equality was not mentioned in the Review Terms of Reference. An interim Review report was released in March 2019, which was also largely silent on gender issues. We examine the submissions to the Review to assess whether, and how, organisations have considered gender equality. We found an almost universal gender blindness in submissions and conclude that this may have contributed to the Review panel ignoring gender equality issues in their interim report. We further conclude that without a focus on gender equality within the Review and ensuing reforms, the APS gender equality strategy is rendered merely symbolic. We recommend the Review implement gender mainstreaming to ensure gender equality can progress in the APS.

ObjectiveUnselected population‐based BRCA testing provides the opportunity to apply genomics on a population‐scale to maximise primary prevention for breast‐and‐ovarian cancer. We compare long‐term outcomes of population‐based and family‐history (FH)/clinical‐criteria‐based BRCA testing on psychological health and quality of life.DesignRandomised controlled trial (RCT) (ISRCTN73338115) GCaPPS, with two‐arms: (i) population‐screening (PS); (ii) FH/clinical‐criteria‐based testing.SettingNorth London Ashkenazi‐Jewish (AJ) population.Population/SampleAJ women/men.MethodsPopulation‐based RCT (1:1). Participants were recruited through self‐referral, following pre‐test genetic counselling from the North London AJ population.Inclusion criteria: AJ women/men >18 years old; exclusion‐criteria: prior BRCA testing or first‐degree relatives of BRCA‐carriers.Interventions: Genetic testing for three Jewish BRCA founder‐mutations: 185delAG (c.68_69delAG), 5382insC (c.5266dupC) and 6174delT (c.5946delT), for (i) all participants in PS arm; (ii) those fulfilling FH/clinical criteria in FH arm. Linear mixed models and appropriate contrast tests were used to analyse the impact of BRCA testing on psychological and quality‐of‐life outcomes over 3 years.Main outcome measuresValidated questionnaires (HADS/MICRA/HAI/SF12) used to analyse psychological wellbeing/quality‐of‐life outcomes at baseline/1‐year/2‐year/3‐year follow up.ResultsIn all, 1034 individuals (691 women, 343 men) were randomised to PS (n = 530) or FH (n = 504) arms. There was a statistically significant decrease in anxiety (P = 0.046) and total anxiety‐&‐depression scores (P = 0.0.012) in the PS arm compared with the FH arm over 3 years. No significant difference was observed between the FH and PS arms for depression, health‐anxiety, distress, uncertainty, quality‐of‐life or experience scores associated with BRCA testing. Contrast tests showed a decrease in anxiety (P = 0.018), health‐anxiety (P < 0.0005) and quality‐of‐life (P = 0.004) scores in both PS and FH groups over time. Eighteen of 30 (60%) BRCA carriers identified did not fulfil clinical criteria for BRCA testing. Total BRCA prevalence was 2.9% (95% CI 1.97–4.12%), BRCA1 prevalence was 1.55% (95% CI 0.89–2.5%) and BRCA2 prevalence was 1.35% (95% CI 0.74–2.26%).ConclusionPopulation‐based AJ BRCA testing does not adversely affect long‐term psychological wellbeing or quality‐of‐life, decreases anxiety and could identify up to 150% additional BRCA carriers.Tweetable abstractPopulation BRCA testing in Ashkenazi Jews reduces anxiety and does not adversely affect psychological health or quality of life.
Configurational demographic predictors of work–nonwork satisfaction
Authors: Farivar Farveh , Richardson Julia 
Published: September 2019

AbstractContemporary work–life balance research tends to treat demographic variables as moderators, grouping variables, or control variables influencing work and nonwork satisfaction. Yet earlier theories were premised on the assumption that they are, in fact, predictors of work and nonwork satisfaction even though those assumptions have not yet been tested empirically. Drawing on an Australian study comprising 798 white‐collar employees and using a fuzzy‐set qualitative comparative analysis technique, we investigate demographic variables as potential configurational predictors affecting work–nonwork satisfaction, defined as a combination of work satisfaction and nonwork satisfaction. The analysis revealed different scenarios and specific patterns between configurational solution terms leading to work–nonwork satisfaction. Employment status and age of children (specifically age differences between children) were the most important demographic variables influencing employees' work–nonwork satisfaction.

Published: September 2019

AbstractThis study aimed to identify consumers’ preferences and impressions of minimally processed “Gala” cultivar apples, using preference tests and word associations. The study was conducted online via the Google Docs tool and sent out via social networks. The participants were 607 individuals, mostly women, mainly between the ages of 18 and 45, with education up to undergraduate and postgraduate level. As regards the preference for minimally processed apples, the profile of the consumer did not influence the choice. The profiles analyzed were gender and education. For the word association test, 11‐word categories were formed, and among these, the most important aspect was appearance, followed by taste and texture, which was confirmed by correspondence analysis. Sample A (0 days—no storage) was the most preferred one, differing significantly from the other samples, whereas sample B (3 days of storage) and sample C (6 days of storage) were associated with characteristics for choice of product. The word association methodology revealed the consumer's impressions of the product, in addition to demonstrating simplicity, low cost, speed, and an exploratory character.Practical ApplicationGender and level of schooling did not influence the choice of minimally processed apples. Appearance was the most cited word in the word association test. Word association is a simple, fast, inexpensive, and projective technique.
Effects of magnesium, phosphate and zinc supplementation in ICU patients—Protocol for a systematic review
Authors: Vesterlund Gitte Kingo , Thomsen Thordis , Møller Morten Hylander , Perner Anders 
Published: September 2019

BackgroundDepletion of the trace elements magnesium, phosphate and zinc is common in patients admitted to the intensive care unit (ICU). Observational studies have suggested worse outcome in patients with hypomagnesaemia, hypophosphataemia or hypozincaemia, but also inverse associations with worse outcome with too high serum levels. However, it is unclear whether data from randomised clinical trials (RCTs) confirm this. Accordingly, we plan to assess the balance between benefits and harms of supplementation as compared with placebo or no supplementation in adult ICU patients.MethodsWe will conduct a systematic review of RCTs with meta‐analysis and trial sequential analysis in accordance with the Cochrane Handbook for Systematic Reviews of Interventions, the Preferred Reporting Items for Systematic Review and Meta‐Analysis (PRISMA) statement and the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach. We will assess the effects of any supplementation with magnesium, phosphate or zinc vs. placebo or no treatment in adult ICU patients. We will systematically search the Cochrane CENTRAL, Embase, PubMed, and for unpublished trials: ClinicalTrials.gov, the EU clinical Trials Register and the WHO International Clinical Trials Registry Platform. The primary outcomes will be days alive without mechanical ventilation and overall mortality. Secondary outcomes include use for mechanical ventilation, tachy‐arrhythmias, use of vasopressors, length of hospital stay and use of renal replacement therapy.DiscussionThe benefits and harms of supplementation therapy with magnesium, phosphate and zinc in general ICU patients are unknown. This outlined systematic review will provide data on the evidence, on which future recommendations for supplementation may be founded.
Low‐ versus high‐dose intraoperative opioids: A systematic review with meta‐analyses and trial sequential analyses

Published: September 2019

BackgroundOpioid‐induced hyperalgesia is a state of nociceptive sensitisation secondary to opioid administration. The objective of this meta‐analysis was to test the hypothesis that high‐dose intraoperative opioids contribute to increased post‐operative pain and hyperalgesia when compared with a low‐dose regimen in patients under general anaesthesia.MethodsWe followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement guidelines and rated the certainty of evidence with the Grading of Recommendations, Assessment, Development and Evaluation system. Only trials investigating pain outcomes and comparing two different dosages of the same intraoperative opioid in patients under general anaesthesia were included. The primary outcome was pain score (analogue scale, 0‐10) at 24 post‐operative hours. Secondary outcomes included pain score and cumulative intravenous morphine equivalents (mg) consumed at 2 post‐operative hours, together with mechanical pain threshold (g·mm−2).ResultsTwenty‐seven randomised controlled trials, including 1630 patients, were identified. Pain score at rest at 24 post‐operative hours was increased in the high‐dose group (mean difference [95% CI]: −0.2 [−0.4, −0.1]; trial sequential analysis‐adjusted CI: −0.4, −0.02; low certainty of evidence). Similarly, at 2 post‐operative hours, both pain score (mean difference [95% CI]: −0.4 [−0.6, −0.2]; low certainty of evidence) and cumulative intravenous morphine equivalents consumed (mean difference [95% CI]: −1.6 mg [−2.6, −0.7]; low certainty of evidence) were significantly higher in the high‐dose group. Finally, the threshold for mechanical pain was significantly lower in the high‐dose group (mean difference to pressure [95% CI]: 3.8 g·mm−2 [1.8, 5.8]; low certainty of evidence).ConclusionsThere is low certainty of evidence that high‐dose intraoperative opioid administration increases pain scores in the post‐operative period, when compared with a low‐dose regimen.
