Proposal for a new method for analyzing the domino effect in an oil refinery and its impact on the environment
Authors: Smaiah Meriem , Djebabra Mebarek , Boubaker Leila 
Published: May 2019

Purpose
The purpose of this paper is to propose a new managerial method to integrate the environmental dimension in the domino effects (DEs) analysis.

Design/methodology/approach
The proposed method is a three-step approach: identification of primary hazards in the form of potential events causing the DE, a mixed quantification (deterministic and probabilistic) of the risk of the DEs with a view to its control and capitalizing the results from the BLEVESOFT software as well as those relating to the probability of occurrence of the DEs in the form of a prioritized action plan dedicated to surrounding environments (proximity territory).

Findings
The primary hazards are technologically manageable at the studied system but are unpredictable if triggered at the environmental subsystem because they are difficult to be managed and often cause panic, which is a form of a very catastrophic DE.

Research limitations/implications
The research could affect members of the engineering and construction industry, and can be applied in several domains since it studies the DE phenomenon. which is a common problem especially in industrials plants.

Practical implications
The proposal method is applied in an industrial terminal in Algeria.

Originality/value
This paper presents an exploratory study of using a new managerial method that aims to combine the potentialities of geomatic sciences that allow the spatial representation of nearby territories to assess the severity of DEs through a deterministic approach, and the modeling of DEs as well as their analysis by a probabilistic approach.
Unveiling the relationship between e-HRM, impersonal trust and employee productivity
Authors: Iqbal Naveed , Ahmad Mansoor , Allen Matthew M.C. 
Published: May 2019

Purpose
This study draws upon social exchange theory to explore the role of impersonal trust as an intermediate value-creating factor between electronic human resource management (e-HRM) and productivity. The purpose of this paper is to seek the antecedents and consequences of impersonal trust within organisations to provide a holistic view of e-HRM and employee productivity. This is the first study to examine how impersonal trust mediates the relationship between e-HRM and employee productivity.

Design/methodology/approach
The data were collected through a large-scale survey of 700 line managers in Pakistani banks. The data were analysed using structure equation modelling.

Findings
The empirical results validate all of the study’s hypotheses, including the role of impersonal trust, which partially mediates the relationship between e-HRM and employee productivity. The results provide empirical evidence that technology-enabled HRM supports organisations by enhancing organisational trust and productivity outcomes.

Originality/value
Such findings contribute to the HRM literature: e-HRM and organisational trust are key predictors for improving employee productivity. The existing literature suggests that e-HRM has a positive impact on employees’ trust in the HRM department. The results provide valuable insights for HR practitioners allowing them to enhance employee productivity by using e-HRM to improve employees’ trust in the organisation.
Business schools’ competitive strategies: whose goals, which aims?
Authors: Ojala Anu M. 
Published: May 2019

PurposeThis study reviews the literature on business-school (b-school) competition and competitiveness to extend our understanding of b-schools’ competitive strategies.Design/methodology/approachBoth content and network analysis were used in the examination of the scholarly discourse.FindingsThe analyses distinguish three literature streams. The first concentrates on resources, capabilities and competencies; the second focuses on measures of competitiveness; and the third includes competitive dynamics and strategy discourse. The analysis shows that the conceptions of competitiveness are quite coherent concerning resources, capabilities and competencies. However, in the “measures of competitiveness” and “industry dynamics and strategy,” discourses were more diverse, indicating greater ambiguity in how the core competencies, capabilities and resources are portrayed as competitiveness outside the institutions. The literature suggests that the measures and indicators of competitiveness are ambiguous to external stakeholders and, furthermore, reflect institutional goal ambiguity.Originality/valueThe question of how, and to what extent, increasing competition in management education and research catalyzes unwelcome changes in the industry has been of great concern to management educators and scholars. This has given rise to a considerable body of literature referring to b-school competition. Despite its topicality, this discourse has remained theoretically fragmented and separate from the mainstream strategy literature. Therefore, this study provides a review and critical discussion of the current state of research on b-school competition, as well as proposes avenues for future research and tools for strategic management of b-schools.
Leadership styles and workplace ostracism among frontline employees
Authors: Kanwal Irsa , Lodhi Rab Nawaz , Kashif Muhammad 
Published: May 2019

Purpose
The purpose of this study is to examine critical associations of transformational leadership, Laissez-faire leadership, transactional leadership, and authoritative leadership styles to predict perceived workplace ostracism among frontline employees (FLEs).

Design/methodology/approach
A snow-ball sampling technique is employed to collect data from 250 FLEs working in the telecommunication sector of Pakistan. The data are collected by means of a self-reported questionnaire.

Findings
All of the hypotheses are supported by the results. The authoritative leadership, transactional leadership, and Laissez-Faire leadership styles are found to positively relate to workplace ostracism while transformational leadership style is found to negatively relate to workplace ostracism.

Practical implications
The managers working in customer service organizations in general and telecom sector in particular should offer leadership training programs to transform supervisors (i.e., in their roles as being the leaders) by re-shaping their thinking as visionary leaders of future. Furthermore, the study has implications to strengthen the communication mechanisms by seeking opinions from FLEs about the leadership styles of their supervisors. This is to ensure that leaders actually transform themselves from being a highly traditional leader to more participative and positive leaders.

Originality/value
The relationships of different leadership styles to study their impact on workplace ostracism and the context of telecommunication service sector of Pakistan are unique to this study.
Microbial “gardening” by a seaweed holobiont: Surface metabolites attract protective and deter pathogenic epibacterial settlement
Authors: Saha Mahasweta , Weinberger Florian 
Published: May 2019

Abstract

Epimicrobial communities on seaweed surfaces usually contain not only potentially pathogenic but also potentially beneficial micro‐organisms. Capacity of terrestrial plants for chemically mediated recruitment, that is, “gardening” of bacterial communities in the rhizosphere was recently demonstrated. Empirical evidence directly linking such chemical “gardening” with the beneficial role of gardened microbes in terrestrial plants is rare and largely missing for aquatic macrophytes.

Here, we demonstrate that our model invasive seaweed holobiont Agarophyton vermiculophyllum possesses beneficial microbiota on its surface that provide protection from bacterial pathogens. Metabolites from the algal holobiont’s surface reduced settlement of opportunistic pathogens but attracted protective epibacterial settlement.

We tested 58 different bacterial species (isolated from the surface of A. vermiculophyllum) individually in tip bleaching assays. Kordia algicida was identified as a “significant pathogen” inducing a bleaching disease. In addition, nine other species significantly reduced the risk of algal bleaching and were thus “significantly protective”. Additionally, two “potential pathogens” and 10 “potential protectors” were identified. When 19 significant and potential protectors and 3 significant and potential pathogens were tested together, the protective strains fully prevented bleaching, suggesting that a component of A. vermiculophyllum’s epimicrobiome provides an associational defence against pathogens. Chemically mediated selective recruitment of microbes was demonstrated in bioassays, where A. vermiculophyllum surface metabolites attracted the settlement of protective strains, but reduced settlement of pathogens.

Synthesis. The capacity of an aquatic macrophyte to chemically “garden” protective micro‐organisms to the benefit of strengthened disease resistance is demonstrated for the first time. Such a role of surface chemistry in “gardening” of microbes as found in the current study could also be applicable to other host plant—microbe interactions. Our results may open new avenues towards manipulation of the surface microbiome of seaweeds via chemical “gardening,” enhancing sustainable production of healthy seaweeds.
An Empirical Analysis of Double Round Auctions
Authors: Kallberg Jarl G. , Liu Crocker H. , Nowak Adam 
Published: May 2019

AbstractThis article analyzes auctions that can feature two bidding rounds for the sale of a single good. In the first round, the seller, after analyzing the received bids, may elect to have k bidders rebid. The highest bidder in the second round then acquires the asset at the highest bid price. We use a sample of 67 properties that sold through this auction process. The 40 hotels in this sample are matched to a control group of 157 hotel properties that were sold in the conventional manner in order to develop a hedonic model for “conventional” sale prices. Using this model, we find that the double round auction mechanism increases the seller's expected revenue significantly: Specifically, in our sample, we estimate that the expected value of a double round auction bid is 8.4% higher than the estimated price if the property were sold using traditional methods. In addition, we show that the average bid is not significantly different from the estimated sale price. We further find (controlling for property characteristics) that the average bid increases by 3.7% from the first to the second round.

Published: May 2019

BackgroundBased upon experimental animal studies, the neurodevelopmental abnormalities associated with prenatal alcohol exposure (PNAE)/fetal alcohol spectrum disorder (FASD) have been attributed, at least in part, to epigenetic modifications. However, there are no direct analyses of human brain tissue.MethodsImmunohistochemical detection of global epigenetic markers was performed on temporal lobe samples of autopsied fetuses and infants with documented PNAE. They were compared to age‐, sex‐, and postmortem delay‐matched control cases (18 pairs; 20 to 70.5 weeks postconception). Temporal lobe tissue from a macaque monkey model of PNAE was also studied (5.7 to 6 months of age). We used antibodies targeting 4 DNA cytosine, 4 histone methylation, and 6 histone acetylation modifications and assigned scores based upon the semiquantitatively graded intensity and proportion of positively labeled nuclei in the ventricular and subventricular zones, ependyma, temporal cortex, temporal white matter, dentate gyrus (DG), and CA1 pyramidal layer.ResultsTemporal changes were identified for almost all marks according to the state of maturation in the human brain. In the DG (and 3 other brain regions), a statistically significant increase in H3K9ac was associated with PNAE. Statistically significant decreases were seen among 5mC, H3K4me3, H3K9ac, H3K27ac, H4K12ac, and H4K16ac in select regions. In the macaques, H3K36me3 decreased in the DG, and the ependyma showed decreases in 5fC and H3K36me3.ConclusionsIn human brain, global intranuclear epigenetic modifications are brain region and maturation state‐specific. These exploratory results support the general hypothesis that PNAE is associated with a global decrease in DNA methylation, a global decrease in histone methylation, and a global increase in histone acetylation. Although the human and monkey subjects are not directly comparable in terms of brain maturation, considering the rapid temporal changes in global epigenetic modifications during brain development, interspecies comparisons may be extremely difficult.

Published: May 2019

BackgroundAcute methanol poisoning leads to optic neuropathy and necrotic lesions of basal ganglia (BG) and subcortical white matter. Survivors of methanol poisoning exhibit long‐term executive and memory deficits. Associations between brain volumetry parameters and cognitive sequelae of methanol poisoning are not known. The aim of our study was to identify long‐term associations between the cognitive performance of survivors of methanol poisoning and the volume of the brain structures that are selectively vulnerable to methanol.MethodsWe conducted a cross‐sectional follow‐up study on a sample of patients (n = 33, age 50 ± 14 years, 82% males) who survived acute methanol poisoning during methanol mass poisoning outbreak from September 2012 till January 2013 in the Czech Republic. A battery of neuropsychological tests and brain magnetic resonance imaging were included in the clinical examination protocol. Specific brain structures (putamen, globus pallidus, nucleus caudatus, and frontal white matter) were selected as regions of interest, and their volumes were estimated using the MorphoBox prototype software.ResultsIn robust multiple regression models, sustained visual attention performance (as assessed by Trail Making Test and Prague Stroop Test) was positively associated with BG structures and frontal white matter volumes (Wald = 9.03 to 85.50,p < 0.01), sensitivity to interference (as assessed by Frontal Battery Assessment) was negatively associated with frontal white matter volume (Wald = 35.44 to 42.25,p < 0.001), and motor performance (as assessed by Finger Tapping Test) was positively associated with globus pallidus and frontal white matter volumes (Wald = 9.66 to 13.29,p < 0.01).ConclusionsOur results demonstrate that smaller volumes of elements of BG–thalamocortical circuitry, namely the BG and frontal white matter, relate to attention and motor performance in methanol poisoning from a long‐term perspective. Disruption of those functional circuits may underlie specific cognitive deficits observed in methanol poisoning.

AbstractObjectiveTo compare clinical and functional outcomes of regional and urban patients after transcatheter aortic valve implantation for severe aortic stenosis.MethodsData were collected at patient follow‐up post‐transcatheter aortic valve implantation at 30 days and 12 months. Patients were stratified by residential postcodes into remoteness areas using the Australian Statistical Geography Standard.DesignRetrospective cohort study.SettingSingle‐centre tertiary referral hospital.ParticipantsPatients undergoing transcatheter aortic valve implantation (n = 142) from 2009 to 2018 were analysed, with 77 patients (54.2%) residing in regional Victoria and New South Wales.Main outcome measuresProcedural success, adverse event rates, readmission rates, mortality rates, loss to follow‐up and functional improvement.ResultsPatients residing in regional areas had a lower mean age (81.8 vs 83.7 years) and proportion of Stage 4 or 5 chronic kidney disease (1.3% vs 9.2%), compared with urban patients. Procedural characteristics and immediate post‐procedural outcomes were similar between both groups. There was no statistically significant difference in mortality, readmission rates or loss to follow‐up between the two cohorts. Regional patients demonstrated poorer rates of functional improvement at 30 days (50.7% vs 67.7%); however, this difference was not sustained at 12 months (79.2% vs 71.0%). Frailty was demonstrated to be an independent predictor of poor 30‐day functional improvement.ConclusionRegional patients treated with transcatheter aortic valve implantation for severe aortic stenosis have non‐inferior 30‐day and 12‐month outcomes, when compared with urban patients. Frailty is a predictor of poor functional improvement post‐transcatheter aortic valve implantation.

Published: May 2019

AbstractAimHearing loss in infants is often diagnosed late, despite universal screening programmes. Risk factors of hearing impairment in high‐risk neonates, identified from population‐based studies, can inform policy around targeted screening. Our aim was to determine the prevalence and the risk factors of hearing loss in a high‐risk neonatal population.MethodsThis was a retrospective cohort study of neonates hospitalised at the University Hospital Cologne, Germany from January 2009 to December 2014 and were part of the newborn hearing screening programme. Multivariable regression analyses using the lasso approach was performed.ResultsData were available for 4512 (43% female) neonates with a mean gestational age at birth of 35.5 weeks. The prevalence of hearing loss was 1.6%, and 42 (0.9%) neonates had permanent hearing loss. Craniofacial anomalies, hyperbilirubinaemia requiring exchange transfusion, oxygen supplementation after 36 weeks of gestation and hydrops fetalis showed associations with permanent hearing loss.ConclusionOur findings of risk factors for hearing loss were consistent with other studies. However, some commonly demonstrated risk factors such as perinatal infections, meningitis, sepsis and ototoxic drugs did not show significant associations in our cohort. Targeted screening based on risk factors may help early identification of hearing loss in neonates.

SummaryBackgroundTreatment for coeliac disease is a lifelong strict gluten‐free diet. Although guidelines recommend regular follow‐up with dietary interviews and coeliac serology, these methods may be inaccurate.AimTo evaluate the usefulness of faecal gluten immunogenic peptides to support the diagnosis and to determine the adherence to the gluten‐free diet in coeliac children.MethodsMulticentre prospective observational study including 64 coeliac children. Faecal gluten peptides, and tissue transglutaminase and deamidated gliadin peptide antibodies were analyzed at diagnosis, and 6, 12 and 24 months thereafter. Gluten consumption was estimated from gluten peptide levels.ResultsMost children (97%) had detectable gluten peptides at diagnosis. On a gluten‐free diet, the rate of gluten peptides increased from 13% at 6 months to 25% at 24 months. Mean estimated gluten exposure dropped from 5543 mg/d at diagnosis to 144 mg/d at 6 months, then increased to 606 mg/d by 24 months. In contrast, deamidated gliadin peptide antibodies normalised and only 20% had elevated tissue transglutaminase antibody by 24 months. The elevation of tissue transglutaminase antibody was more prolonged in patients with detectable gluten peptides (P < 0.05). Nevertheless, absolute levels of tissue transglutaminase antibody had low sensitivity to identify patients with detectable gluten peptides (P > 0.1). Dietitian assessment was only moderately correlated with gluten peptide detection (κ = 0.5).ConclusionsFaecal gluten peptides testing may guide treatment of coeliac disease prior to diagnosis and during the assessment diet adherence. Further studies could determine if early identification of gluten exposure reduces the need for expensive/invasive investigations for non‐responsive coeliac disease.
