Seed-skewness algorithm for X-ray diffraction signal detection in time-resolved synchrotron Laue photocrystallography
Authors: Szarejko Dariusz , Kamiński Radosław , Łaski Piotr , Jarzembska Katarzyna N. 
Published: February 2020

A one-dimensional seed-skewness algorithm adapted for X-ray diffraction signal detection is presented and discussed. The method, primarily designed for photocrystallographic time-resolved Laue data processing, was shown to work well for the type of data collected at the Advanced Photon Source and European Synchrotron Radiation Facility. Nevertheless, it is also applicable in the case of standard single-crystal X-ray diffraction data. The reported algorithm enables reasonable separation of signal from the background in single one-dimensional data vectors as well as the capability to determine small changes of reflection shapes and intensities resulting from exposure of the sample to laser light. Otherwise, the procedure is objective, and relies only on skewness computation and its subsequent minimization. The new algorithm was proved to yield comparable results to the Kruskal–Wallis test method [Kalinowski, J. A. et al. (2012). J. Synchrotron Rad.
19, 637], while the processing takes a similar amount of time. Importantly, in contrast to the Kruskal–Wallis test, the reported seed-skewness approach does not need redundant input data, which allows for faster data collections and wider applications. Furthermore, as far as the structure refinement is concerned, the reported algorithm leads to the excited-state geometry closest to the one modelled using the quantum-mechanics/molecular-mechanics approach reported previously [Jarzembska, K. N. et al. (2014). Inorg. Chem.
53, 10594], when the t and s algorithm parameters are set to the recommended values of 0.2 and 3.0, respectively.
Music subculture as a source of conspicuous consumption practices: a qualitative content analysis of “altered movement” songs and music videos
Authors: Castillo-Villar Fernando Rey , Cavazos-Arroyo Judith , Kervyn Nicolas 
Published: February 2020

Purpose
The purpose of this study is to focus on analyzing the role of music subcultures in the communication and promotion of conspicuous consumption practices. The object of study is the “altered movement” as the music style of the drug subculture in Mexico.

Design/methodology/approach
A qualitative content analysis of 78 lyrics and music videos of “altered movement” was carried out between August and December 2018.

Findings
The analysis of lyrics and music videos leads to the identification of four narratives (from poor to rich, power through violence, lavish lifestyle and power over women) and diverse symbolic markers (luxury brands mainly) that together, display messages aimed at promoting conspicuous consumption practices.

Originality/value
The current research expands the body of literature of music subcultures in the consumer research area by contesting the common conception of this phenomenon as a healthy source of self-identity formation and deepening into its role as a source of conspicuous consumption practices.
MCMC and GLMs for estimating regression parameters
Authors: ELsayed Mahmoud , Soliman Amr 
Published: February 2020

Purpose
The purpose of this study is to estimate the linear regression parameters using two alternative techniques. First technique is to apply the generalized linear model (GLM) and the second technique is the Markov Chain Monte Carlo (MCMC) method.

Design/methodology/approach
In this paper, the authors adopted the incurred claims of Egyptian non-life insurance market as a dependent variable during a 10-year period. MCMC uses Gibbs sampling to generate a sample from a posterior distribution of a linear regression to estimate the parameters of interest. However, the authors used the R package to estimate the parameters of the linear regression using the above techniques.

Findings
These procedures will guide the decision-maker for estimating the reserve and set proper investment strategy.

Originality/value
In this paper, the authors will estimate the parameters of a linear regression model using MCMC method via R package. Furthermore, MCMC uses Gibbs sampling to generate a sample from a posterior distribution of a linear regression to estimate parameters to predict future claims. In the same line, these procedures will guide the decision-maker for estimating the reserve and set proper investment strategy.

Green closed-loop supply chain network design considering cost control and CO2 emission
Authors: Huang Lufei , Murong Liwen , Wang Wencheng 
Published: February 2020

PurposeEnvironmental issues have become an important concern in modern supply chain management. The structure of closed-loop supply chain (CLSC) networks, which considers both forward and reverse logistics, can greatly improve the utilization of materials and enhance the performance of the supply chain in coping with environmental impacts and cost control.Design/methodology/approachA biobjective mixed-integer programming model is developed to achieve the balance between environmental impact control and operational cost reduction. Various factors regarding the capacity level and the environmental level of facilities are incorporated in this study. The scenario-based method and the Epsilon method are employed to solve the stochastic programming model under uncertain demand.FindingsThe proposed stochastic mixed-integer programming (MIP) model is an effective way of formulating and solving the CLSC network design problem. The reliability and precision of the Epsilon method are verified based on the numerical experiments. Conversion efficiency calculation can achieve the trade-off between cost control and CO2 emissions. Managers should pay more attention to activities about facility operation. These nodes might be the main factors of costs and environmental impacts in the CLSC network. Both costs and CO2 emissions are influenced by return rate especially costs. Managers should be discreet in coping with cost control for CO2 emissions barely affected by return rate. It is advisable to convert the double target into a single target by the idea of “Efficiency of CO2 Emissions Control Reduction.” It can provide managers with a way to double-target conversion.Originality/valueWe proposed a biobjective optimization problem in the CLSC network considering environmental impact control and operational cost reduction. The scenario-based method and the Epsilon method are employed to solve the mixed-integer programming model under uncertain demand.
The winners of legislative mandate: An analysis of post‐parliamentary career positions in Germany and the Netherlands

Published: February 2020

AbstractLittle is known about the careers of parliamentarians after they leave parliament. We analyse the post‐parliamentary careers of German and Dutch parliamentarians over the last 20 years and document the presence of a persistent and substantial gender gap. This gap exists regardless of party, country or political position and persists even when the status of the pre‐parliamentary profession and achievement within parliament are controlled for. Aside from demonstrating our findings, we offer new insights into possible explanations for the dynamics behind them. Additionally, we show that parliament only serves as a stepping stone for a more successful career for a relatively small share of politicians: only 32 per cent of MPs obtain more attractive positions in the public or private sector after their legislative service.
Typical reactive carbonyl compounds in food products: Formation, influence on food quality, and detection methods

Published: February 2020

AbstractReactive carbonyl compounds are a large group of highly reactive electrophilic compounds containing one or more carbonyl groups, which can be created by lipid oxidation both in vivo and in food. Malondialdehyde (MDA) and 4‐hydroxy‐2‐nonenel (HNE) are the two most important reactive carbonyl compounds in food. They can react with proteins and nucleic acids and cause biological damage to cells and lead to carbonyl stress. Therefore, they are regarded as representative products of lipid oxidation, toxic molecules, and biomarkers of oxidative stress. Apart from biological toxicity, they can also react with myoglobin and myofibrillar protein and further affect color, gel properties, hydrophobicity, or other properties of food. However, the effects of MDA and HNE on food qualities have not received as much attentions and it is noteworthy that the existing analytical methods for detecting MDA and HNE have a variety of limitations due to the complexity of food samples. To provide a comprehensive understanding of HNE and MDA, the formation mechanism, occurrence, and analytical methods for MDA and HNE in food matrix were summarized in this article. Emphasis is focused on formation mechanism including non‐enzymatic pathway and enzymatic pathway, and detection methods including the extraction methods, the new development of sample pre‐treatment technology and the selection of derivative reagents. Impressively, the reaction mechanism of MDA and HNE with myoglobin or myofibrillar protein is also described to explain how MDA and HNE affect food quality.

AbstractIntroductionDiabetic patients with peripheral arterial disease (PAD) are challenging to assess. Non‐contrast magnetic resonance angiography (MRA) offers a safe alternative in patients with renal impairment. The study objective is to evaluate accuracy of lower limb quiescent‐interval single‐shot (QISS) MRA and pedal QISS‐arterial spin‐labelled (ASL) MRA for detection of significant stenosis in diabetic patients with PAD.MethodsCombined QISS and QISS‐ASL MRA was performed in 32 diabetic PAD patients (20 male, 12 female; mean 69 years; 8 with critical ischaemia). Two readers assessed haemodynamically significant (>50%) stenosis and diagnostic confidence on MRA, against digital subtraction angiography (DSA) as the reference standard, with subgroup analysis of patients with severe renal impairment (n = 7). Inter‐reader agreement of stenosis and diagnostic confidence were evaluated. Test–retest reproducibility was evaluated in 10 subjects who underwent repeat MRA on a different day.ResultsAt DSA, 262/645 segments (40.6%) had haemodynamically significant stenoses. MRA accuracy was 78.1% (478/612) and 75.6% (464/614), sensitivity 64.7% (161/249) and 77.5% (193/249), and specificity 87.3% (317/363) and 74.2% (271/365) for 2 readers. MRA accuracy was 80.9% and 80.7% for readers 1 and 2, respectively, in patients with severe renal impairment. QISS MRA but not pedal QISS‐ASL MRA was considered of diagnostic image quality. Inter‐reader agreement was moderate for stenosis (ĸ = 0.60) and diagnostic confidence (ĸ = 0.41). Test–retest reproducibility was high (ĸ = 0.87) and moderate (ĸ = 0.54) for individual readers.ConclusionsQuiescent‐interval single‐shot MRA has reasonable accuracy in a diabetic PAD population with high burden of disease, providing a non‐contrast option in patients with renal impairment. QISS‐ASL MRA requires further optimisation to be clinically feasible.

Abstract

Close‐range photogrammetry (CRP) is a well‐established technique to retrieve quantitative information from objects using photography. CRP is often used in morphology studies when the direct handling of individuals is unpractical or unethical, or to reduce processing costs and time. Although multiple software to extract quantitative information from 3D reconstructions of objects exist, tools for 2D CRP are scarce and often tailored for specific applications.

We present AragoJ, a cross‐platform, open‐source, Java based software designed to integrate and streamline all 2D CRP workflow steps in a single program.

AragoJ allows the user to perform all the main tasks involved in obtaining measurements from digital pictures, namely: (1) performing camera calibration and correcting radial picture distortions; (2) calculating a scaling factor either by: (a) utilizing a scale in the picture, or (b) based on camera specifications (focal distance and digital sensor size) and distance to object; (3) measuring and scaling the relevant traits in the photographs; (4) obtaining information from pictures’ digital metadata files; and (5) exporting measurements and metadata to a comma separated values file.

AragoJ was designed to be versatile and unconstrained, in order to be useful for 2D CRP studies across multiple disciplines. The software, source code and detailed documentation are available from https://github.com/AzWhaleLab/AragoJ.

AbstractExtracorporeal life support is increasingly used in the treatment of patients presenting with cardiogenic shock or in need of cardiopulmonary resuscitation. Identifying therapeutic targets and factors associated with the prognosis are highly desirable. The present study analyzed the impact of interleukin 6 and 8 on the outcome of patients undergoing venoarterial extracorporeal membrane oxygenation (VA ECMO). Interleukin 6 and 8 serum levels of 329 patients were analyzed prior to, on days 1 and 5 of VA ECMO therapy. Interleukin 6 and 8 serum levels of surviving and nonsurviving patients were compared. At time points with significant differences, receiver operating characteristics and cutoff levels were analyzed to determine the prognostic value of interleukin serum levels. Survival analysis was performed to compare patients above and below cutoff levels. Interleukin 6 serum levels were significantly elevated in nonsurviving patients prior to VA ECMO initiation. Interleukin 6 and 8 serum levels in nonsurviving patients were significantly elevated on day 1 of VA ECMO. Receiver operating characteristics analysis revealed significant prognostic impact of interleukin 6 and 8 on day 1 of VA ECMO (AUC 0.70 and 0.72). Survival analysis comparing patients above and below the cutoff showed a 1‐year survival of 32.6% for IL6 and 20.8% for IL8 above, as well as 66.9% for IL6 and 61.9% for IL8 below the cutoff (P < .05). Interleukin 6 and 8 serum levels demonstrated prognostic value early in VA ECMO therapy. The technical applicability of interleukin reduction raises interest in interleukins 6 and 8 as therapeutic targets.

AbstractAimTo examine how children with sleep‐disordered breathing express their own sleep through drawing.MethodsChildren hospitalised for a sleep study in a sleep laboratory of a tertiary hospital were asked to draw a human figure and themselves while asleep. Characteristics of the two drawings were analysed and compared along with a descriptive analysis of some drawings.ResultsChildren with sleep‐disordered breathing and an associated disorder, n = 34, age 5‐11 years, participated in the study. The size of the human figure, the colours used, the orientation of the sheet, the type of drawing strokes and the objective quality of the drawing were comparable between the two drawings. On the sleep drawing, 71% of the children drew a bed, 15% drew themselves asleep, 19% represented snoring and 12% night elements. Sixty‐two per cent of the children preferred the human drawing to the sleep drawing. A descriptive analysis of 12 drawings showed the influence of the associated disorder on the two drawings.ConclusionThis study showed how the associated disease of children with sleep‐disordered breathing infiltrated their imaginary life. The sleep drawing gave useful information about representation, fears and wishes in relation to the associated disease and the child's sleeping.
“It was emotional”—A group for people with learning disabilities to talk about end of life
Authors: Reilly Deirdre Emer , Raymond Kathryn , O'Donnell Chris 
Published: February 2020

Accessible summary

People with a learning disability told us people do not talk to them about death.

This is about a group we ran to help people learn about death and the end of their life.

The group talked about people who had died and what might happen when they die.

People in the group wanted help to talk to their own parents about what might happen when their parents die.

People did not have enough information about the cost of funerals.

The group was important as it helped people to learn. Some people made plans for what they would like to happen when they die.

AbstractBackgroundAcademic research and reports from healthcare professionals tell us people with learning disabilities are not routinely supported to learn about end‐of‐life issues or make plans for the end of their lives.MaterialsQuestionnaires were used to check how much people knew. Accessible symbols were used to help people understand end‐of‐life specific terms.MethodPartnering with a charity, three sessions were held in three consecutive weeks to ask people in a convened group what they wanted to know and help them learn. The sessions supported people to start creating their own plans for funerals, where they want to die and what should happen with their possessions.ResultsThis group had between 21 and 23 (N = 23) attendees each week and all except one person came back after the first week. The participants were keen to highlight what they did not know and learn about end‐of‐life issues. They also wanted support to plan for the end of their lives and their parents' lives, and the group tried to provide information and support on these topics.ConclusionThis group was a valuable exercise that was very much needed by local people with learning disabilities. The group will run again and should be offered in other areas. Groups of this kind can offer unmet needs that are highlighted by national guidance in England, UK such as the NHS long‐term plan and the Learning Disability Mortality Review Programme.
Depression, drugs and dental anxiety in prisons: A mediation model explaining dental decay experience
Authors: Arora Garima , Humphris Gerry , Lahti Satu , Richards Derek , Freeman Ruth 
Published: February 2020

AbstractObjectiveTo test a theoretical mediation model and investigate whether drug use and/or dental anxiety act as mediating factors between depression and dental decay experience among prisoners.MethodA cross‐sectional survey was conducted on a convenience sample of 300 prisoners across three prison establishments in Scotland. Depression and dental anxiety were measured using the Centre for Epidemiological Studies Depression Scale and the Modified Dental Anxiety Scale, respectively. Drug use was assessed using three yes (scoring 1)/ no (scoring 0) questions: ‘ever taken (illegal) drugs’, ‘injecting drugs’ and ‘ever participated in a rehabilitation programme’. Participants had an oral examination to determine dental caries experience (missing [MT] and untreated decay [D3cvT]) in all four quadrants. Latent variable path analysis was conducted to test the mediation model.ResultsA total of 342 prisoners participated, of which 298 yielded a complete data set. Depression was associated with missing teeth and untreated decay (D3T) through an indirect pathway (Total standardized indirect effects = 0.11, P < .01) via drug use and dental anxiety (X2 [71] = 89.8, P = .07; Root Mean Square Error of Approximation: 0.03; Comparative Fit Index: 0.994 and Tucker‐Lewis index: 0.992). Twenty‐two percent of the variance in untreated decay and missing teeth was explained by both drug use and dental anxiety; however, the strongest predictor was drug use (total standardized direct effects = 0.45, P < .001).ConclusionA relatively simple model to assist understanding dental decay experience of people in prison has been proposed. The data collected were consistent with our specified model. Drug use acted as the primary mediator and dental anxiety as a secondary mediator between depression and dental decay experience. Given the co‐morbidity between mental health and drug use and dental decay experience, an integrated or shared approach is proposed. We recommend that future research should concentrate on building a firmer picture by replicating and extending the framework presented.
Factors associated with provider self‐efficacy in delivery of evidence‐based programs for children, youth, and families
Authors: Shapiro Cheri J. , Charest Emilie 
Published: February 2020

AbstractInvestments in training real‐world behavioral health providers in evidence‐based programs (EBPs) can be costly; thus, it is important to understand which providers may be more or less likely to implement such approaches after training. Provider self‐efficacy is associated with implementation of EBPs, but research on factors associated with provider self‐efficacy is less common. An exploratory, cross‐sectional, quantitative survey examined factors associated with provider self‐efficacy among 150 real‐world service providers who reported delivering EBPs to children, youth, or families in one U.S. state. Factors found to be associated with higher self‐efficacy included profession, workplace support, and extent of training received; difficulty engaging families was associated with lower self‐efficacy. Self‐efficacy was found to be associated with program use but not fidelity. Several organization‐level variables were identified as both facilitators and barriers to implementation of EBPs. Implications for research and practice are discussed.
