Authors: Abd El-Gawad Walaa M. , Ahmed Nivin M. , Selim Mohamed M. , Hamed E. , Souaya Eglal R. 
Published: June 2019

Purpose
In recent years, zeolites have been highlighted as a new component in many industrial applications owing to their unique properties. The purpose of this study is to apply three prepared types of zeolites Na-X, Na-Y and hydroxysodalite (Na-HS) in anticorrosive paint formulations to be evaluated as a partial replacement to zinc phosphate in anticorrosive paint formulations to protect carbon steel.

Design/methodology/approach
The three types of zeolites were characterized using different instrumental analysis such as X-ray diffraction, scanning electron microscopy and X-ray fluorescence. Evaluation of zeolites was done using American society for material and testing. Then, they were incorporated in paint formulations based on medium oil-modified soya-bean dehydrated castor oil alkyd resin in the presence and absence of zinc phosphate. Their corrosion behavior was estimated using both immersion test and electrochemical impedance measurements in 3.5% NaCl.

Findings
Generally, the prepared zeolites exhibited good corrosion protection performance, but in presence of zinc phosphate the performance was better. This proves that, zeolites by themselves can resist corrosion but not efficiently, while in presence of zinc phosphate and owing to a synergistic effect between them, the performance was better. This opens the way to partial replacement of zinc phosphate with another safer and cheaper ingredient, which is zeolite.

Practical implications
The three zeolites can be applied in many industries besides the paint industry, such as reinforcing filler in rubber, plastics and ceramic composites, also can be applied in paper filling, paper coatings and electrical insulation.

Originality/value
The three zeolites are environmentally friendly materials that can partially replace other expensive anticorrosive pigments (e.g. zinc phosphate).

Published: June 2019

PurposeA growing number of schools are now implementing quality management systems (QMS). As a result, studies are being conducted to assess the educational benefits of these systems and their capacity to identify areas for improvement in school processes and performance. The purpose the present study is to assess the impact of ISO:9001 implementation on teaching-learning processes in the classroom, and in schools with at least three years’ experience of applying this standard.Design/methodology/approachTo this end, a questionnaire was administered to a final sample of 2,185 subjects from 80 pre-school, primary and secondary education schools in the regions of Madrid, Castile and León, Andalusia and Valencia (Spain).FindingsThe results show that ISO:9001 implementation yielded a higher than average impact on teaching-learning processes. Specifically, improvements were observed in the subdomains of tutorials, evaluation and classroom teaching methodologies as a result of implementing this QMS.Originality/valueThis impact was higher in state-subsidized private schools in Valencia and Andalusia with over nine years’ experience of ISO:9001 in schools with internal funding plans and in those with fewer than 29 teachers on the staff.
Behavioral biases in pension fund trustees’ decision making
Authors: Weiss-Cohen Leonardo , Ayton Peter , Clacher Iain , Thoma Volker 
Published: June 2019

PurposeBehavioral finance research has almost exclusively investigated the decision making of lay individuals, mostly ignoring more sophisticated institutional investors. The purpose of this paper is to better understand the relatively unexplored field of investment decisions made by pension fund trustees, an important subset of institutional investors, and identify future avenues of further exploration.Design/methodology/approachThis paper starts by setting out the landscape in which pension fund trustees operate and make their decisions, followed by a literature review of the extant behavioral finance research applicable to similar situations.FindingsDespite receiving training and accumulating experience in financial markets, these are limited and sparse; therefore, pension fund trustees are unlikely to be immune from behavioral biases. Trustees make decisions in groups, are heavily reliant on advice and make decisions on behalf of others. Research in those areas has uncovered many inefficiencies. It is still unknown how this specific context can affect the psychological effects on their decisions.Research limitations/implicationsGiven how much influence trustees’ decisions have on asset allocation and by extension in financial markets, this is a surprising state of affairs. Research in behavioral finance has had a marked influence on policy in the past and so we anticipate that exploring the decisions made within pension funds may have wide ramifications for the industry.Originality/valueAs far as the authors are aware, no behavioral research has empirically tested pension fund trustees’ decisions to investigate how the combination of group decisions, advice and surrogacy influence their decisions and, ultimately, the sustainability of our pensions.
A method for real-time error detection in low-cost environmental sensors data
Authors: Loyola Mauricio 
Published: June 2019

Purpose
The purpose of this paper is to propose a simple, fast, and effective method for detecting measurement errors in data collected with low-cost environmental sensors typically used in building monitoring, evaluation, and automation applications.

Design/methodology/approach
The method combines two unsupervised learning techniques: a distance-based anomaly detection algorithm analyzing temporal patterns in data, and a density-based algorithm comparing data across different spatially related sensors.

Findings
Results of tests using 60,000 observations of temperature and humidity collected from 20 sensors during three weeks show that the method effectively identified measurement errors and was not affected by valid unusual events. Precision, recall, and accuracy were 0.999 or higher for all cases tested.

Originality/value
The method is simple to implement, computationally inexpensive, and fast enough to be used in real-time with modest open-source microprocessors and a wide variety of environmental sensors. It is a robust and convenient approach for overcoming the hardware constraints of low-cost sensors, allowing users to improve the quality of collected data at almost no additional cost and effort.

Authors: Evans Simon Chester , Barrett Julie , Mapes Neil , Hennell June , Atkinson Teresa , Bray Jennifer , Garabedian Claire , Russell Chris 
Published: June 2019

Purpose
The benefits of “green dementia care”, whereby people living with dementia are supported to connect with nature, are increasingly being recognised. Evidence suggests that these benefits span physical, emotional and social spheres and can make a significant contribution towards quality of life. However, care settings often present specific challenges to promoting such connections due to a range of factors including risk-averse cultures and environmental limitations. The purpose of this paper is to report on a project that aims to explore the opportunities, benefits, barriers and enablers to interaction with nature for people living with dementia in residential care and extra care housing schemes in the UK.

Design/methodology/approach
Data were gathered from 144 responses to an online survey by managers/staff of extra care housing schemes and care homes in the UK. In depth-case studies were carried out at three care homes and three extra care housing schemes, involving interviews with residents, staff and family carers.

Findings
A wide variety of nature-based activities were reported, both outdoor and indoor. Positive benefits reported included improved mood, higher levels of social interaction and increased motivation for residents, and greater job satisfaction for staff. The design and layout of indoor and outdoor spaces is key, in addition to staff who feel enabled to promote connections with nature.

Research limitations/implications
This paper is based on a relatively small research project in which the participants were self-selecting and therefore not necessarily representative.

Practical implications
The paper makes some key recommendations for good practice in green dementia care in extra care housing and care homes.

Social implications
Outdoor activities can promote social interaction for people living with dementia in care settings. The authors’ findings are relevant to the recent policy focus on social prescribing.

Originality/value
The paper makes some key recommendations for good practice in green dementia care in extra care housing and care homes.
Impacts of rainfall extremes predicted by climate‐change models on major trophic groups in the leaf litter arthropod community
Authors: Wise David H. , Lensing Janet R. 
Published: June 2019

AbstractArthropods in the leaf litter layer of forest soils influence ecosystem processes such as decomposition. Climate‐change models predict both increases and decreases in average rainfall. Increased drought may have greater impacts on the litter arthropod community. In addition to affecting survival or behaviour of desiccation‐sensitive species, lower rainfall may indirectly lower abundances of consumers that graze drought‐stressed fungi, with repercussions for higher trophic levels.We tested the hypothesis that trophic structure will differ between the two rainfall scenarios. In particular, we hypothesized that densities of several broadly defined trophic groupings of arthropods would be lower under reduced rainfall.To test this hypothesis, we used sprinklers to impose two rainfall treatments during three growing seasons in roofed, fenced 14‐m2plots and documented changes in abundance from initial, pre‐treatment densities of 39 arthropod taxa. Experimental plots were subjected to either LOW (fortnightly) or HIGH (weekly) average rainfall based upon climate models and the previous 100 years of regional weekly averages. Unroofed open plots, our reference treatment (REF), experienced higher than average rainfall during the experiment.The two rainfall extremes produced clear negative effects of lowered rainfall on major trophic groups. Broad categories of fungivores, detritivores and predators were more abundant in HIGH than LOW plots by the final year. Springtails (Collembola), which graze fungal hyphae, were 3× more abundant in the HIGH rainfall treatment. Taxa of larger‐bodied fungivores and detritivores, spiders (Araneae), and non‐spider predators were 2× more abundant under HIGH rainfall. Densities of mites (Acari), which include fungivores, detritivores and predators, were 1.5× greater in HIGH rainfall plots. Abundances and community structure of arthropods were similar in REF and experimental plots, showing that effects of rainfall uncovered in the experiment are applicable to nature.This pattern suggests that changes in rainfall will alter bottom‐up control processes in a critical detritus‐based food web of deciduous forests. Our results, in conjunction with other findings on the impact of desiccation on arthropods and fungal growth, suggest that drier conditions will depress densities of fungal consumers, causing declines in higher trophic levels, with possible impacts on soil processes and the larger forest food web.
T‐bet interferes with PD‐1/PD‐L1‐mediated suppression of CD4+ T cell inflammation and survival in Crohn's disease
Authors: Ma Fei , Zhao Mingning , Song Zhenyu , Wang Zhongchuan 
Published: June 2019

AbstractPathogenic inflammation mediated by overactive type 1 helper T cell (Th1) responses could exacerbate and perpetuate Crohn's disease. Programmed death (PD)‐1 and its ligand PD‐L1 pathway could be upregulated to suppress inflammation. We wondered why this pathway is ineffective at suppressing pathogenic Th1 inflammation in Crohn's disease patients. Here, we found that overexpression of T‐bet via transfection significantly reduced the expression of PD‐1. PD‐L1 was capable of suppression proinflammatory CD4+ T cells, but T‐bet transfection significantly reduced the susceptibility of CD4+ T cells toward PD‐L1‐mediated suppression, evidenced by the observations that at low PD‐L1 concentration T‐bet transfected and mock transfected CD4+ T cells presented comparable IL‐2 production, but at high PD‐L1 concentration, T‐bet transfected CD4+ T cells presented significantly higher IL‐2 than mock transfected CD4+ T cells. PD‐L1 could significantly reduce the survival of CD4+ T cells from Crohn's disease patients, but interestingly, in the absence of PD‐L1, the survival was better in mock transfected CD4+ T cells, while in the presence of PD‐L1, the survival was better in T‐bet transfected CD4+ T cells. Crohn's disease patients with greater severity presented higher T‐bet expression and lower PD‐1 expression in CD4+ T cells, demonstrating an association between T‐bet expression and disease progression. We also discovered that stimulation with bacterial antigens could upregulate the expression of T‐bet. Together, this study demonstrated that T‐bet overexpression could interfere with PD‐1/PD‐L1‐mediated suppression of CD4+ T cell inflammation and survival, and potentially contributed to the development and persistence of Crohn's disease.

Published: June 2019

AbstractThe neutrophil gelatinase‐associated lipocalin (NGAL) receptor (24p3R) is expressed in distal nephron and contributes to the endocytosis of NGAL in urine. This study was undertaken to evaluate an influence of renal ischaemia‐reperfusion injury on 24p3R. Unilateral renal pedicle was clamped for 0, 10, 20, 30, or 45 minutes in male Wistar rats. Urine was collected for 24 hours after reperfusion, and ischaemic kidney and blood sample were obtained. Apparent histological injury in the ischaemic kidney was detected in the 30 and 45 minutes‐treated groups. Urinary NGAL excretion elevated in rats with renal ischaemia for more than 20 minutes, while serum creatinine increased in rats for more than 30 minutes of ischaemia. Renal protein expression of NGAL did not significantly change. Renal mRNA expressions of megalin and cubilin, which are expressed at renal proximal tubules and uptake NGAL, decreased in animals with renal ischaemia for more than 20 minutes. Renal protein expression of 24p3R, which is expressed at renal distal tubules and uptake NGAL, decreased in rats with renal ischaemia for 45 min. This study showed for the first time that renal 24p3R decreased in response to renal ischaemia. As relatively longer renal ischaemia (45 minutes) decreased renal 24p3R protein and increased urinary NGAL excretion, the down‐regulation of 24p3R protein might contribute to the elevated urinary excretion of NGAL in rats with unilateral ischaemia‐reperfusion injury.
‘Get out of Traian Square!’: Roma Stigmatization as a Mobilizing Tool for the Far Right in Timişoara, Romania
Authors: Creţan Remus , O'brien Thomas 
Published: June 2019

AbstractPost‐communist Central and Eastern Europe has seen far right movements and parties gain considerable ground by drawing on nativist and ethnic claims to call for a return to an imagined past. In Romania, far right groups have been able to capitalize on a sense of injustice while also playing on historically negative feelings towards the Roma community. These patterns have been observed in Timişoara, where the group Noua Dreaptă (New Right) has established a foothold over the past decade by emphasizing claims that blame the Roma for loss of built heritage and corruption in the administration of property restitution. The aims of this article are to examine the emergence of Noua Dreaptă and its use of Roma stigmatization, and to consider the ways in which extreme views are normalized by appealing to beliefs and perceptions. The findings of the article show that pre‐existing prejudices can be a powerful force that not only targets marginalized communities, but also challenges administrative practices and builds organizational support. At the level of the city, it is possible to identify the way in which these claims can be more precisely calibrated to draw on concerns that circulate within the community.
Understanding the Relations Among the Storage, Soaking, and Cooking Behavior of Pulses: A Scientific Basis for Innovations in Sustainable Foods for the Future

Published: June 2019

AbstractThe world faces challenges that require sustainable solutions: food and nutrition insecurity; replacement of animal‐based protein sources; and increasing demand for convenient, nutritious, and health‐beneficial foods; as well as functional ingredients. The irrefutable potential of pulses as future sustainable food systems is undermined by the hardening phenomenon that develops upon their storage under adverse conditions of temperature and relative humidity. Occurrence of this phenomenon indicates storage instability. In this review, the application of a material science approach, in particular the glass transition temperature concept, is presented to explain phenomena of storage instability such as the occurrence of hardening and loss of viability under adverse storage conditions. In addition to storage (in)stability, application of this concept during processing of pulses is discussed. The state‐of‐the‐art on how hardening occurs, that is, mechanistic insights, is provided, including a critical evaluation of some of the existing postulations using recent research findings. Moreover, the influence of hardening on the properties and processing of pulses is included. Prevention of hardening and curative actions for pulses affected by the hardening phenomenon are described in addition to the current trends on uses of pulses and pulse‐derived products. Based on the knowledge progress presented in this review, suggestions for the future include: first, the need for innovation toward implementation of recommended solutions for the prevention of hardening; second, the optimization of the identified most effective and efficient curative action against hardening; and third, areas to focus on for elucidation of mechanisms of hardening, although existing analytical methods require advancement.

Published: June 2019

AbstractPrediction facial features from the skull are recurring theme on the forensic literature. The nose has been investigated since it has a significant role in facial recognition and the literature shows that there is not an universal method for nasal prediction. This study aimed to conduct a systematic review to analyze what are the most consistent techniques of nasal reconstruction. Primary studies describing or validating nasal reconstruction techniques in adults and published in journals of Forensic Sciences were included in this review. Tedeschi‐Oliveira's method positioned nasal tip with acceptable accuracy as Gerasimov's method. The Krogman's and Iscan's technique underestimated nasal projection in North Americans. The Prokopec's and Ubelaker's method obtained accuracy in Caucasoid. George's method presented results similar to reference standard in Caucasoid. In a supplementary way, studies are needed to accurately estimate the nasal width.

Published: June 2019

AbstractThe fall armyworm, Spodoptera frugiperda, is a species native to the Americas and has spread to many countries in Africa and Asia in recent years. Proactive actions for potential invasion of S. frugiperda to China coordinated by government agencies and agricultural extension systems resulted in timely detection in January 2019 in Yunnan province neighboring onto Myanmar. The extensive monitoring in southern provinces of China since February 2019 resulted in dynamic tracking of S. frugiperda spreading to 13 provincial regions in China within 4 months by May 10, 2019, which is crucial for timely management actions in the fields. The first detections of S. frugiperda (corn strain) in China were confirmed using cytochrome oxidase subunit 1 (CO1) and triosephosphate isomerase (Tpi) genes molecular marker method. In addition to S. frugiperda, larvae of three other noctuid species with similar morphological appearance (S. litura, S. exigua and Mythimna separata) can occur simultaneously and cause similar damage in cornfields in southern China. Thus, we can use both morphological and molecular marker methods to compare larval stages of four noctuid species. Further, we discuss the risk of potential spread of invasive S. frugiperda to other regions and impact on corn production in China.

Published: June 2019

AbstractBackgroundAlthough diabetes is associated with ethnicity and worse cardiac surgery outcomes, no research has been done to study the effect of both diabetes and ethnicity on cardiac surgery outcomes in a multiethnic Southeast Asian cohort. Hence, this study aimed to delineate the association of ethnicity on outcomes after cardiac surgery among diabetics in a multiethnic Southeast Asian population.MethodsPerioperative data from 3008 adult patients undergoing elective cardiac surgery from 2008 to 2011 at the two main heart centers in Singapore was analyzed prospectively, and confirmatory analysis was conducted with the generalized structural equation model.ResultsDiabetes was significantly associated with postoperative acute kidney injury (AKI) and postoperative hyperglycemia. Postoperative AKI, Malay ethnicity, and blood transfusion were associated with postoperative dialysis. Postoperative AKI and blood transfusion were also associated with postoperative arrhythmias. In turn, postoperative dialysis and arrhythmias increased the odds of 30‐day mortality by 7.7‐ and 18‐fold, respectively.ConclusionsThis study identified that diabetes is directly associated with postoperative hyperglycemia and AKI, and indirectly associated with arrhythmias and 30‐day mortality. Further, we showed that ethnicity not only affects the prevalence of diabetes, but also postoperative diabetes‐related outcomes.
