Published: June 2018

SummaryContamination of peanut oil is a great concern in the industry. FTIR spectroscopy combined with chemometrics could develop a rapid and nondestructive method to screen aflatoxin‐contaminated peanut oil. Aflatoxin B1 (AFB1)‐ and aflatoxin (AFT)‐positive peanut oils were screened by mid‐IR (MIR) with classification models established by a novel multivariate decision tree (MDT) method. Two discriminant functions were developed in the fingerprint region based on absorbance ratio and moving window Fisher discrimination analysis methods for the two complex nodes in each MDT model. Window adjustment reduced the total different spectral data points in modelling to 23. The true‐positive and true‐negative rate of calibration and validation could both reach up to 100%. These results would render the possibility of efficient and economical design of a portable high‐speed multitasking MIR instrument for screening AFB1‐ and AFT‐contaminated peanut oil.
Comparison of different oleogels in processed cheese products formulation
Authors: Huang Huidong , Hallinan Robert , Maleky Farnaz 
Published: June 2018

SummaryThis study investigates the potential usage of unsaturated vegetable oil oleogel to replace solid milk fat in processed cheese products (PCPs). Soybean oil was gelled using rice bran wax (RBW) or sunflower wax (SW) at two different concentrations and used to produce PCPs with final concentrations of 0.5% or 1% wax. An ungelled oil PCP and a commercial milk fat processed cheese (CC) were produced for comparison. Upon compositional analysis, moisture and fat content were similar between oleogel PCPs (OPCP) and the CC sample; however, lower saturated fat content was observed in the OPCPs. Samples’ microscopy analysis revealed that the incorporation of oleogels reduced oil agglomeration observed in the ungelled PCPs, which confirms the presence of a higher oil holding capacity in the OPCPs. Rheological and thermomechanical analysis demonstrated comparable hardness, storage modulus and meltability values between the OPCPs and the control samples. This study provides insight into the potential applications for oleogels in the replacement milk fat in processed cheese products with desirable properties.
Life Satisfaction and the UK Citizenship Process: Do Tests and Ceremonies Enhance Immigrants’ Lives?
Authors: Bartram David 
Published: June 2018

AbstractGaining citizenship in the UK requires applicants to pass a “Life in the UK” test and (if successful) attend a citizenship ceremony. Critics of this policy agenda assert that it exacerbates exclusion of an already vulnerable and disadvantaged population. The UK government justifies the requirements in part on the basis that they facilitate integration, thus enhancing immigrants’ lives. This article, using data from the UK longitudinal household survey (“Understanding Society”) considers outcomes for immigrants by investigating whether gaining citizenship in the current period is associated with immigrants’ subjective well‐being. Results from regression models and matching analyses show that participating in the citizenship process (or not) is not generally associated with individuals’ life satisfaction.

Published: June 2018

AbstractIn this study, we investigated the Al–Sn flux system and its growth conditions to obtain AlN single crystals. AlN single crystals of a size of 50 μm were successfully grown using an Al–Sn melt under nitrogen gas pressure. The growable region of the AlN crystals was established using a pressure‐temperature diagram. The required nitrogen gas pressure for the growth of the AlN crystals was found to decrease with increasing temperature, and AlN was grown at 0.1 MPa nitrogen pressure above 1300°C. By investigating the AlN yield with various Al concentrations, we confirmed that the Al component in the Al–Sn melt facilitated nitrogen dissolution. Finally, scanning electron microscopy analysis showed that the obtained AlN particles showed good morphology.
Synthesis, densification, and microstructure of TaC‐TaB2‐SiC ceramics
Authors: Gu Junfeng , Xiang Mingyu , Ji Wei , Wang Weimin , Wang Hao , Fu Zhengyi 
Published: June 2018

AbstractThe usual way to prepare TaC‐TaB2 ceramics by adding B4C to TaC leads to formation of residual C, which degrades samples’ mechanical properties. To eliminate the residual C, we suggest incorporating Si together with B4C into TaC ceramics, resulting in new ultrahigh‐temperature ceramics (TaC‐TaB2‐SiC). Dense ceramics (>99%) with SiC volume fraction ranging from 15.86% to 41.04% were fabricated by reactive spark plasma sintering at 1900°C for 5 minutes. The formation of SiO2‐based transient liquid phase was evidenced by the “film” in intermediate products, which can promote densification. The fine‐grained microstructure in final products was found to be associated with the in situ formed SiC, which impeded TaC and TaB2 grains from coarsening by the pinning effect. Besides, ultrafine TaB2 grains (~100 nm) produced during the reaction and then rearranged in liquid also contributed to grain refinement. Compared to TaC‐TaB2(‐C) ceramics prepared from TaC and B4C, the acquired composites exhibit better mechanical properties, due to their fine‐grained microstructures and the elimination of residual C.

Published: June 2018

AbstractPolycrystalline Ni(Cr1−xMnx)2O4 (0.1 ≤ x ≤ 0.325) ceramic samples were studied through different protocols of dc magnetization measurements. The samples exhibit 2 kinds of magnetic compensation effects below the ferrimagnetic transition temperature TC. Remarkable magnetization reversal is observed between the 2 compensation temperatures Tcomp1 and Tcomp2, which is regarded as arising from the negative exchange coupling between the 2 magnetic sublattices at different crystallographic sites. The magnetization is reversed at TSR due to spin‐reorientation caused by magnetostructural coupling. The spin‐reorientation is supported by Mn substitution and TSR is increased to 96 K when x reaches 0.325. However, it is suppressed due to the strong ionic site preference and thus the magnetization is slightly increased in the negative direction of the magnetic field. Near the 2 compensation temperatures, tunable magnetic switching effects can be obtained just by changing the magnitude of the applied magnetic field. Moreover, both normal and inverse magnetocaloric effects were also demonstrated.

AbstractA new type of (0.7−x)Bi0.5Na0.5TiO3‐0.3Sr0.7Bi0.2TiO3‐xLaTi0.5Mg0.5O3 (LTM1000x, x = 0.0, 0.005, 0.01, 0.03, 0.05 wt%) lead‐free energy storage ceramic material was prepared by a combining ternary perovskite compounds, and the phase transition, dielectric, and energy storage characteristics were analyzed. It was found that the ceramic materials can achieve a stable dielectric property with a large dielectric constant in a wide temperature range with proper doping. The dielectric constant was stable at 2170 ± 15% in the temperature range of 35‐363°C at LTM05. In addition, the storage energy density was greatly improved to 1.32 J/cm3 with a high‐energy storage efficiency of 75% at the composition. More importantly, the energy storage density exhibited good temperature stability in the measurement range, which was maintained within 5% in the temperature range of 30‐110°C. Particularly, LTM05 show excellent fatigue resistance within 106 fatigue cycles. The results show that the ceramic material is a promising material for temperature‐stable energy storage.
The impact of mandatory IFRS reporting on institutional trading costs: Evidence from Australia
Authors: Lepone Andrew , Wong Jin Boon 
Published: June 2018

AbstractThis study examines the impact of mandatory International Financial Reporting Standards (IFRS) on the market quality of the Australian Securities Exchange (ASX) 200 constituent stocks. Using traditional metrics that are consistent with prior literature (i.e., bid‐ask spreads), the first stage analysis confirms that stock liquidity has improved. However, when the analysis is extended to consider the trading costs incurred by market participants (i.e., execution shortfall), results suggest liquidity has not changed significantly. The paper utilizes rich unique datasets that contain detailed trade information, and findings are robust after controlling for trade difficulty and market conditions. In the era of High Frequency Trading (HFT) and occurrences of ‘fleeting’ liquidity, this paper provides some evidence that while IFRS may have enhanced ‘visible’ bid‐ask spreads, tangible liquidity for market participants, particularly global institutional investors, has not improved significantly.

AbstractBackgroundDermoscopy revealed to be extremely useful in the diagnosis of early melanoma, the most important limitation being its subjectivity in giving a final diagnosis. To overcome this problem, several algorithms and checklists have been proposed. However, they generally demonstrated modest level of diagnostic accuracy, unsatisfactory concordance between dermoscopists and/or poor specificity.ObjectiveTo test a new methodological approach for the differentiation between early melanoma and atypical nevi, based on an integrated clinical‐anamnestic dermoscopic risk scoring system (iDScore).MethodsWe selected a total of 435 standardized dermoscopic images of clinically atypical melanocytic skin lesion (MSL) excised in the suspect of malignancy (i.e. 134 early melanomas – MM – and 301 atypical nevi). Data concerning patient age and sex and lesion dimension and site were collected. A scoring classifier was designed based on this data set integrated with the dermoscopic evaluations performed by three experts blinded to histological diagnosis.ResultsA total of seven dermoscopic structures, three age groups (30–40 years, 41–60 years and >60 years), two maximum diameter categories (5–10 mm and >10 mm) and three body areas (i.e. frequently, chronically and seldom photoexposed sites) were selected by the scoring classifier as interdependently significant variables. The total risk score (S) of a lesion resulted from the simple sum of partial scores assigned to each selected variable. The iDScore‐aided diagnosis showed an high accuracy (receiver operating characteristic‐area under the curve = 0.903; IC: 95% = 0.887–0.918). A risk‐based criticality scale corresponding to different S ranges was proposed.ConclusionThe iDScore checklist is proposed as a feasible and efficient tool to support dermatologists in non‐invasive differentiation between atypical nevi and early MM on the basis of few selected clinical‐anamnestic data and standardized dermoscopic features.

Published: June 2018

AbstractThis study investigated the potential of comprehensive corrective feedback forms as editing and learning tools and examined their effect on learners’ cognitive and attitudinal engagement. Low‐intermediate second language writers (N = 139) were randomly assigned to four experimental conditions (direct corrections of grammatical errors, metalinguistic codes for grammatical errors, direct corrections of grammatical and nongrammatical errors, or metalinguistic codes for grammatical and nongrammatical errors) and a control group (self‐correction). Results from mixed‐effects linear models showed that although direct corrections and codes were effective for enhancing learners’ immediate grammatical and nongrammatical accuracy (i.e., during text revision), a long‐term advantage (i.e., 4 weeks after feedback provision) was only evident for direct corrections. A mental effort measure of cognitive load revealed that participants’ cognitive load was significantly lower when processing direct corrections targeting grammar issues. Questionnaire answers also yielded a significant attitudinal difference between the direct feedback groups and their metalinguistic counterparts.Open PracticesThis article has been awarded an Open Materials badge.

Breastfeeding practices in the United Kingdom: Is the neighbourhood context important?
Authors: Peregrino Andressa B. , Watt Richard G. , Heilmann Anja , Jivraj Stephen 
Published: June 2018

AbstractBreastfeeding is an important public health issue worldwide. Breastfeeding rates in the United Kingdom, particularly for exclusive breastfeeding, are low compared with other OECD countries, despite its wide‐ranging health benefits for both mother and child. There is evidence that deprivation in the structural and social organisation of neighbourhoods is associated with adverse child outcomes. This study aimed to explore whether breastfeeding initiation, exclusive breastfeeding for at least 3 months, and any type of breastfeeding for at least 6 months were associated with neighbourhood context measured by neighbourhood deprivation and maternal neighbourhood perceptions in a nationally representative U.K. sample. A cross‐sectional analysis was conducted using data from the Millennium Cohort Study. Logistic regression was carried out on a sample of 17,308 respondents, adjusting for individual‐ and familial‐level socio‐demographic characteristics. Neighbourhood deprivation was independently and inversely associated with breastfeeding initiation. Compared with the least deprived areas, the likelihood of initiating breastfeeding was 40% lower in the most deprived neighbourhoods (OR: 0.60, 95% CI [0.50, 0.72]). The relationship between both exclusive and any type of breastfeeding at 3 and 6 months respectively with neighbourhood deprivation after adjustment for potential confounders was not entirely linear. Breastfeeding initiation (OR: 0.78, 95% CI [0.71, 0.85]), exclusivity for 3 months (OR: 0.84, 95% CI [0.75, 0.95]), and any breastfeeding for 6 months (OR: 0.82, 95% CI [0.73, 0.93]) were each reduced by about 20% among mothers who perceived their neighbourhoods lacking safe play areas for children. Policies to improve breastfeeding rates should consider area‐based approaches and the broader determinants of social inequalities.
Functional characterization of an aluminum (Al)‐inducible transcription factor, ART2, revealed a different pathway for Al tolerance in rice
Authors: Che Jing , Tsutsui Tomokazu , Yokosho Kengo , Yamaji Naoki , Ma Jian Feng 
Published: June 2018

Summary

High aluminum (Al) tolerance in rice (Oryza sativa) is controlled by a Cys2His2‐type zinc finger transcription factor ART1 (Al resistance transcription factor 1). There are five close homologs of ART1 in the rice genome, but the role of these homologs is unknown.

We functionally characterized one of the ART1 homologs, ART2, in terms of tissue and spatial expression, subcellular localization, transcriptional activation activity, and phenotypic analysis of the knockout lines.

ART2 was localized to the nucleus and showed a transcriptional activation potential in yeast. ART2 was mainly expressed in the roots, but the expression level was much lower than that of ART1. The ART2 expression was rapidly induced by Al in the roots of the wild‐type rice, but not in art1 mutant. Knockout of ART2 resulted in increased sensitivity to Al toxicity, but did not alter sensitivity to different pH values. Expression profile analysis by RNA‐sequencing showed that ART2 was not involved in activation of genes regulated by ART1; however, four genes seems to be regulated by ART2, which are implicated in Al tolerance.

These results indicate that ART1 and ART2 regulate different pathways leading to Al tolerance, and ATR2 plays a supplementary role in Al tolerance in rice.
Conceptualizing resilience in adult mental health literature: A systematic review and narrative synthesis
Authors: Ayed Nadia , Toner Sarah , Priebe Stefan 
Published: June 2018

PurposeThis review aims to identify how the term ‘resilience’ is conceptualized across adult mental health research due to ongoing criticism regarding the lack of consistency in its conceptualization.MethodA systematic search, including hand searches of book chapters, was conducted using search terms (‘resilien*’) AND (‘mental illness’ OR ‘mental health problem’). Papers were excluded if they did not meet the following criteria: written in English, provide a clear conceptualization of resilience, include only adults (aged 18 + ) in the sample, solely focus on individuals with a primary diagnosis of mental illness, and peer‐reviewed. Data were extracted on conceptualizations of resilience, demographic, and diagnostic variables of the study population, publication year, and the research design used. Conceptualizations were combined and collapsed into overarching themes and then refined through joint discussion, consultation with a third reviewer, and input from a larger multidisciplinary team.ResultsThirty‐one texts (6 book chapters, 4 reviews, 2 appraisals/critical evaluations, 1 editorial, and 18 research projects) were included. Two broad understandings of resilience were identified: resilience as a process and resilience as a characteristic of an individual. Processes comprise three themes: ‘immunity’, ‘bouncing back’, and ‘growth’, whilst characteristics are captured in two themes ‘personal resources’ and ‘social resources’.ConclusionsThese findings suggest that resilience can be conceptualized in a clear and meaningful manner in adult mental health research. The five themes reflect distinct ways of using the term resilience. Whilst each one of them may have merit in future research, it appears beneficial to make clear in research which exact conceptualization of resilience has been adopted.Practitioner Points

When considering and reading about ‘resilience’, one should be aware that there are different concepts of it.

The main difference is between resilience as a personal characteristic and resilience as a process.

Therapy may address resilience as a personal characteristic by utilizing individual and social resources.

The therapeutic process may be understood as resilience in form of bouncing back and personal growth.
Production of complex viral glycoproteins in plants as vaccine immunogens
Authors: Margolin Emmanuel , Chapman Ros , Williamson Anna‐Lise , Rybicki Edward P. , Meyers Ann E. 
Published: June 2018

SummaryPlant molecular farming offers a cost‐effective and scalable approach to the expression of recombinant proteins which has been proposed as an alternative to conventional production platforms for developing countries. In recent years, numerous proofs of concept have established that plants can produce biologically active recombinant proteins and immunologically relevant vaccine antigens that are comparable to those made in conventional expression systems. Driving many of these advances is the remarkable plasticity of the plant proteome which enables extensive engineering of the host cell, as well as the development of improved expression vectors facilitating higher levels of protein production. To date, the only plant‐derived viral glycoprotein to be tested in humans is the influenza haemagglutinin which expresses at ~50 mg/kg. However, many other viral glycoproteins that have potential as vaccine immunogens only accumulate at low levels in planta. A critical consideration for the production of many of these proteins in heterologous expression systems is the complexity of post‐translational modifications, such as control of folding, glycosylation and disulphide bridging, which is required to reproduce the native glycoprotein structure. In this review, we will address potential shortcomings of plant expression systems and discuss strategies to optimally exploit the technology for the production of immunologically relevant and structurally authentic glycoproteins for use as vaccine immunogens.

Published: June 2018

SummaryWhole‐genome sequencing‐based bulked segregant analysis (BSA) for mapping quantitative trait loci (QTL) provides an efficient alternative approach to conventional QTL analysis as it significantly reduces the scale and cost of analysis with comparable power to QTL detection using full mapping population. We tested the application of next‐generation sequencing (NGS)‐based BSA approach for mapping QTLs for ascochyta blight resistance in chickpea using two recombinant inbred line populations CPR‐01 and CPR‐02. Eleven QTLs in CPR‐01 and six QTLs in CPR‐02 populations were mapped on chromosomes Ca1, Ca2, Ca4, Ca6 and Ca7. The QTLs identified in CPR‐01 using conventional biparental mapping approach were used to compare the efficiency of NGS‐based BSA in detecting QTLs for ascochyta blight resistance. The QTLs on chromosomes Ca1, Ca4, Ca6 and Ca7 overlapped with the QTLs previously detected in CPR‐01 using conventional QTL mapping method. The QTLs on chromosome Ca4 were detected in both populations and overlapped with the previously reported QTLs indicating conserved region for ascochyta blight resistance across different chickpea genotypes. Six candidate genes in the QTL regions identified using NGS‐based BSA on chromosomes Ca2 and Ca4 were validated for their association with ascochyta blight resistance in the CPR‐02 population. This study demonstrated the efficiency of NGS‐based BSA as a rapid and cost‐effective method to identify QTLs associated with ascochyta blight in chickpea.
Emotional misattribution: Facial muscle responses partially mediate behavioral responses in the emotion misattribution procedure
Authors: Rohr Michaela , Folyi Timea , Wentura Dirk 
Published: June 2018

AbstractThere is ongoing debate regarding the degree to which, and the conditions under which, physiological, affect‐related (i.e., embodied) processes contribute to emotion information processing. Whereas most studies focus on clearly visible and intentional processing conditions, the present study targeted this issue by studying the implicit processing of emotional (angry, fearful, joyful, neutral) faces in a masked emotion misattribution procedure. That is, participants had to categorize neutral‐looking faces with regard to the allegedly felt emotion, which were preceded by a very briefly presented emotional expression. In addition to behavioral measures, facial muscle responses were obtained as an index of physiological, affect‐related processes. Linear mixed‐model mediation analyses confirmed that facial muscle responses partially mediated the behavioral responses to the masked primes in the misattribution task.
