Purpose
Vegetable salads, despite their recognized health benefits, are an increasingly common cause of foodborne illness worldwide. The purpose of this paper is to determine the prevalence of E. coli with virulence genes in ready-to-eat raw mixed vegetable salads sold in collective catering in Abidjan.

Design/methodology/approach
A total of 436 strains of E. coli were isolated from 306 ready-to-eat raw mixed vegetables salads and then identified biochemically and molecularly based on the uidA gene responsible for beta-glucuronidase activity. The virulence genes were determined by polymerase chain reaction.

Findings
The prevalence in vegetable salads of E. coli with virulence genes was 35.3 percent. The distribution of pathovars was 21.2 percent enterotoxigenic (ETEC), 4.9 percent enteropathogenic (EPEC), 0.7 percent Shigatoxigenic (STEC), and 7.5 percent Enteroaggregative E. coli (EAEC). It appears from the study that vegetable salads sold in collective catering in Abidjan are at risk for contamination by E. coli pathovars.

Originality/value
Processing conditions for these salads during preparation appear to be hygienically insufficient, so measures to control the risk of contamination are necessary.
The art of tastings: enhancing the arts festival experience
Authors: Viljoen Armand , Kruger Martinette , Saayman Melville 
Published: August 2018

PurposeThe role and importance of arts festivals are well documented within the festival and events literature. Art and culture, as well as the subsequent enhancement thereof, are especially significant in multicultural societies. However, little is known regarding the role of culinary experiences within an arts festival setting. The paper aims to discuss these issues.Design/methodology/approachThe case study was a well-known and popular Afrikaans national arts festival held annually in Potchefstroom, South Africa. Visitors to three distinct tasting experiences (brandy, whisky and sparkling wine, including Méthode Cap Classique), offered as part of the festival programme, were surveyed.FindingsIn the analyses, 292 completed questionnaires were included, which revealed three managerial factors for a successful tasting experience, as well as six tasting experience dimensions. In all cases, the experiences exceeded the expectations. This research greatly contributes towards the body of knowledge regarding tasting experiences at national arts festivals, an aspect that has not been researched to date.Practical implicationsBased on the results, practical implications are provided to enhance the current tasting experiences as well as visitor loyalty. This research is a stepping stone towards understanding the needs and preferences of the visitors, as well as identifying how the festival can capitalise on delivering these experiences.Originality/valueThis research identified for the first time the factors that contribute to a memorable tasting experience, as well as evaluated the tasting experience dimensions.

Purpose
The purpose of this study is to investigate the effect on flexural strength of fire-damaged concrete repaired with high-strength mortar (HSM).

Design/methodology/approach
Reinforced concrete beams with dimension of 100 mm × 100 mm × 500 mm were used in this study. Beams were then heated to 400°C and overlaid with either HSM or high-strength fiber reinforced mortar (HSFM) to measure the effectiveness of repair material. Repaired beams of different material were then tested for flexural strength. Another group of beams was also repaired and tested by the same procedure but was heated at higher temperature of 600°C.

Findings
Repair of 400°C fire-damaged samples using HSM regained 72 per cent of its original flexural strength, 100.8 per cent of its original toughness and 56.9 per cent of its original elastic stiffness. Repair of 400°C fire-damaged samples using HSFM regained 113.5 per cent of its original flexural strength, 113 per cent of its original toughness and 85.1 per cent of its original elastic stiffness. Repair of 600°C fire-damaged samples using HSM regained 18.7 per cent of its original flexural strength, 25.9 per cent of its original peak load capacity, 26.1 per cent of its original toughness and 22 per cent of its original elastic stiffness. Repair of 600°C fire-damaged samples using HSFM regained 68.4 per cent of its original flexural strength, 96.5 per cent of its original peak load capacity, 71.2 per cent of its original toughness and 52.2 per cent of its original elastic stiffness.

Research limitations/implications
This research is limited to the size of the furnace. The beam specimen is limited to 500 mm of length and overall dimensions. This dimension is not practical in actual structure, hence it may cause exaggeration of deteriorating effect of heating on reinforced concrete beam.

Practical implications
This study may promote more investigation of using HSM as repair material for fire-damaged concrete. This will lead to real-world application and practical solution for fire-damaged structure.

Social implications
The aim of this research in using HSM mostly due to the material’s high workability which will ease its application and promote quality in repair of damaged structure.

Originality/value
There is a dearth of research on using HSM as repair material for fire-damaged concrete. Some research has been carried out using mortar but at lower strength compared to this research.
The impact of switching costs on customer complaint behavior and service recovery evaluation
Authors: Bergel Maxi , Brock Christian 
Published: August 2018

PurposeThe purpose of this paper is to examine the impact of three different dimensions of switching costs on customer dissatisfaction response styles as well as on the evaluation of service recovery.Design/methodology/approachStudy 1 is a scenario-based experiment and Study 2 uses a critical incident technique combined with survey-based measures of switching costs, dissatisfaction responses and perceived complaint handling.FindingsThe results of these studies highlight the need to consider the different effects of switching costs. Not only do different switching costs lead to varying customer dissatisfaction responses, they also have differential moderator effects on the interrelationships between customer-perceived recovery justice and service recovery satisfaction.Research limitations/implicationsService failure severity was an influential control variable. Future studies should investigate how the type, context and severity of service failure influence customers’ complaint behavior. Furthermore, participants had trouble differentiating between their relations toward their service provider in general and one particular employee. Hence, further research should explore the relationship between customers and frontline employees.Practical implicationsThe authors encourage managers to take a closer look at the switching cost dimensions of their service industry. This may lead practitioners to promote differentiated strategies for complaint stimulation and complaint handling.Originality/valueThis is the first study to simultaneously explore all three dimensions of switching costs when examining their impact on customers’ dissatisfaction response styles as well as the moderating effects in the recovery process. In doing so, this study reveals some hitherto uncovered effects.
Go home and kick the dog
Authors: Moon Tae Won , Hur Won-Moo 
Published: August 2018

PurposeThe purpose of this paper is to examine the spillover effects of coworker incivility on customer-directed counterproductive work behavior (CWB) and how emotional exhaustion mediates the relationship between them. The authors predicted that job calling and perceived organizational support (POS) would moderate the relationship between experienced coworker incivility and service employees’ emotional exhaustion, respectively.Design/methodology/approachSurvey data from 252 frontline employees working at six full-service luxury hotels in South Korea were examined.FindingsThe results indicated that experienced coworker incivility was positively related to customer-directed CWB. In addition, the relationship between experienced coworker incivility and customer-directed CWB was mediated by emotional exhaustion. Finally, employees’ job calling attenuated the positive effects of experienced coworker incivility on customer-directed CWB. The theoretical and practical implications of this study are discussed, together with its limitations and future research directions.Originality/valueThe main contribution of the study is to provide an empirical framework for how instances of coworker incivility spillover, which lead to the target employee’s customer-directed CWB through emotional exhaustion, and how personal (e.g. job calling) may buffer against negative effects.
The fall and rise of intellectual capital accounting: new prospects from the Big Data revolution
Authors: La Torre Matteo , Botes Vida L. , Dumay John , Rea Michele Antonio , Odendaal Elza 
Published: August 2018

PurposeAs Big Data is creating new underpinnings for organisations’ intellectual capital (IC) and knowledge management, this paper aims to analyse the implications of Big Data for IC accounting to provide new conceptual and practical insights about the future of IC accounting.Design/methodology/approachBased on a conceptual framework informed by decision science theory, the authors explain the factors supporting Big Data’s value and review the academic literature and practical evidence to analyse the implications of Big Data for IC accounting.FindingsIn reflecting on Big Data’s ability to supply a new value for IC and its implications for IC accounting, the authors conclude that Big Data represents a new IC asset, and this represents a rationale for a renewed wave of interest in IC accounting. IC accounting can contribute to understand the determinants of Big Data’s value, such as data quality, security and privacy issues, data visualisation and users’ interaction. In doing so, IC measurement, reporting and auditing need to keep focusing on how human capital and organisational and technical processes (structural capital) can unlock or even obstruct Big Data’s value for IC.Research limitations/implicationsThe topic of Big Data in IC and accounting research is in its infancy; therefore, this paper acts at a normative level. While this represents a research limitation of the study, it is also a call for future empirical studies.Practical implicationsOnce again, practitioners and researchers need to face the challenge of avoiding the trap of IC accountingisation to make IC accounting relevant for the Big Data revolution. Within the euphoric and utopian views of the Big Data revolution, this paper contributes to enriching awareness about the practical factors underpinning Big Data’s value for IC and foster the cognitive and behavioural dynamic between data, IC information and user interaction.Social implicationsThe paper is relevant to prepares, users and auditors of financial statements.Originality/valueThis paper aims to instill a novel debate on Big Data into IC accounting research by providing new avenues for future research.
Aha! “take on Me’s”: bridging the North sea with relational autoethnography
Authors: Klevan Trude , Karlsson Bengt , Turner Lydia , Short Nigel , Grant Alec 
Published: August 2018

Purpose
The purpose of this paper is to explore how sharing stories of being a mental health professional and academic, based more broadly on serendipity and searching in life, can serve as means for bridging and developing cross-cultural understandings and collaborative work.

Design/methodology/approach
This paper is a relational autoethnography based on face-to-face and written conversational dialogue between five mental health academics from the UK and Norway.

Findings
The very practice of writing this paper displays and serves the purpose of bridging people, cultures and understandings, at several levels, in the facilitation of new research and writing projects. Troubling traditional boundaries between “us” and “them, and the “knower” and the “known,” the writing is theoretically underpinned by Friendship as Method, situated in a New Materialist context.

Originality/value
Through its conversational descriptions and explorations the paper shows how doing relational autoethnography can be purposeful in developing cross-cultural understandings and work at both professional and personal levels. It also demonstrates how autoethnography as relational practice can be useful in the sharing of this methodology between people who are more and less familiar with it.

Published: August 2018

ObjectiveTo examine the association between medical home enrollment and receipt of recommended care for Medicaid beneficiaries with multiple chronic conditions (MCC).Data Sources/Study SettingSecondary claims data from fiscal years 2008–2010. The sample included nonelderly Medicaid beneficiaries with at least two of eight target conditions (asthma, chronic obstructive pulmonary disease, diabetes, hypertension, hyperlipidemia, seizure disorder, major depressive disorder, and schizophrenia).Study DesignWe used linear probability models with person‐ and year‐level fixed effects to examine the association between patient‐centered medical home (PCMH) enrollment and nine disease‐specific quality‐of‐care metrics, controlling for selection bias and time‐invariant differences between enrollees.Data Collection MethodsThis study uses a dataset that links Medicaid claims with other administrative data sources.Principal FindingsPatient‐centered medical home enrollment was associated with an increased likelihood of receiving eight recommended mental and physical health services, including A1C testing for persons with diabetes, lipid profiles for persons with diabetes and/or hyperlipidemia, and psychotherapy for persons with major depression and persons with schizophrenia. PCMH enrollment was associated with overuse of short‐acting β‐agonists among beneficiaries with asthma.ConclusionsThe PCMH model can improve quality of care for patients with multiple chronic conditions.

ObjectiveTo examine the prevalence of concurrent Veterans Health Administration (VA) and non‐VA prescriptions for opioids and sedative‐hypnotic medications among post‐9/11 veterans in Oregon.Data SourcesVA health care and prescription data were probabilistically linked with Oregon Prescription Drug Monitoring Program (PDMP) data.Study DesignThis retrospective cohort study examined concurrent prescriptions among n = 19,959 post‐9/11 veterans, by year (2014–2016) and by patient demographic and clinical characteristics. Veterans were included in the cohort for years in which they received VA outpatient care; those receiving hospice or palliative care were excluded. Concurrent prescriptions were defined as ≥1 days of overlap between outpatient prescriptions for opioids and/or sedative‐hypnotics (categorized as benzodiazepines vs. non‐benzodiazepines).Principal FindingsAmong 5,882 veterans who filled opioid or sedative‐hypnotic prescriptions at VA pharmacies, 1,036 (17.6 percent) filled concurrent prescriptions from non‐VA pharmacies. Within drug class, 15.1, 8.8, and 4.6 percent received concurrent VA and non‐VA opioids, benzodiazepines, and non‐benzodiazepines, respectively. Veteran demographics and clinical diagnoses were associated with the likelihood of concurrent prescriptions, as was enrollment in the Veterans Choice Program.ConclusionsA considerable proportion of post‐9/11 veterans receiving VA care in Oregon filled concurrent prescriptions for opioids and sedative‐hypnotics. Fragmentation of care may contribute to prescription drug overdose risk among veterans.

Published: August 2018

AbstractThe recently developed clustered regularly interspaced short palindromic repeats (CRISPR)‐based techniques have made it possible to reprogram target gene expression without cloning complementary DNA or disturbing genomic sequence in mammalian cells and several multicellular organisms. We previously showed that CRISPR‐associated protein 9 (Cas9) and CRISPR from Prevotella and Francisella 1 (Cpf1) could induce target mutations, deletions, inversions, and duplications both singly and multiplex in silkworm, Bombyx mori. However, it remains unknown whether the CRISPR activation (CRISPRa) system can be used in B. mori. In this study, we investigated the CRISPRa system, in which a nuclease dead Streptococcus pyogenes Cas9 (SpCas9) is fused to two transcription activation domains, including VP64 (a tetramer of the herpes simplex VP16 transcriptional activator domain), and VPR (a tripartite activator, composed of VP64, p65, and Rta). The results showed that both dCas9‐VP64 and dCas9‐VPR systems could be used in B. mori cells, of which the latter showed significantly higher activity. The dCas9‐VPR system showed considerable activity on all five tested target genes, and further analysis revealed that the up‐regulation of genes was negatively correlated to their basal expression level. We also observed that this system could be used to upregulate a range of target genes. Taken together, our findings demonstrate that CRISPRa can be a powerful tool to study gene functions in B. mori and perhaps other non‐drosophila insects.
Fiberoptic intubation of severely obese patients through supraglottic airway: A prospective, randomized trial of the Ambu® AuraGain™ laryngeal mask vs the i‐gel™ airway

Published: August 2018

IntroductionAirway management in severely obese patients remains a challenging issue for anaesthetists and may lead to life‐threatening situations. Supraglottic airway devices, such as the i‐gel™ or the AuraGain™, were developed, with the possibility to ventilate the patient or use them as a conduit for endotracheal intubation.MethodsIn our randomized prospective trial, we hypothesized a 10 seconds faster fiberoptic trans‐device intubation time through the AuraGain™ laryngeal mask compared to the i‐gel™ laryngeal mask in severely obese patients. We randomly assigned 44 patients to the AuraGain or i‐gel group and measured trans‐device intubation time after 5 minutes of successful ventilation through the device. Secondary parameters relating to the trans‐device intubation success, oropharyngeal leak pressure, and parameters regarding insertion of the supraglottic airway devices were measured. Postoperative airway morbidity was determined 5 hours after surgery.ResultsMean (SD) intubation time was 55.7 (5.8) seconds for the AuraGain™ vs 54.1 (8.5) for i‐gel™ mask (95% CI −2.7 to 5.9; P = 0.474), respectively, on a mean body mass index (BMI) of 39.4 kg/m2 in the AuraGain™ group vs 38.9 kg/m2 in i‐gel™ group. No difference could be found in the other studied parameters.ConclusionsTime for intubation through both supraglottic airway devices was similar. Attributed to fast possibility of securing the airway with both supraglottic airway devices, we believe that both, AuraGain™ and i‐gel™, can be a good alternative in the airway management in obese patients.
A bidirectional path analysis model of smoking cessation self‐efficacy and concurrent smoking status: impact on abstinence outcomes
Authors: Clyde Matthew , Pipe Andrew , Reid Robert , Els Charl , Tulloch Heather 
Published: August 2018

AbstractSelf‐efficacy is routinely associated with abstinence in the addictions literature, and is a major component relapse‐prevention models. The magnitude of this relationship has been brought into question following equivocal results in studies controlling for concurrent smoking status. The aim of our study was to clarify the relationship between cessation self‐efficacy, smoking status, and cessation outcomes in a cohort of treatment‐seeking smokers. Smokers participating in the FLEX trial, a randomized trial investigating the efficacy of three pharmacologic treatments for smoking cessation, completed questionnaires assessing cessation self‐efficacy at baseline and at weeks 1, 3, 5 and 10 post‐target quit date; smoking status was verified using expired carbon monoxide. Structural models were fit in order to ascertain the relationship between cessation self‐efficacy and concurrent smoking at each time‐point, and to assess the association between cessation self‐efficacy, smoking and seven‐day point prevalence smoking status at week 10. A total of 737 treatment‐seeking smokers participated. In our path model, self‐efficacy and smoking status at all time points were associated with week 10 abstinence (except week 3 self‐efficacy), after controlling these values' previous time‐points. All direct pathways between cessation self‐efficacy and smoking were also significant, supporting a bidirectional relationship. Our results support a bidirectional and reciprocal relationship between cessation self‐efficacy and concurrent smoking behavior; participants with higher confidence were more likely to be smoke‐free, and concurrent smoking status predicted levels of confidence over the ensuing weeks. Both measures were associated with week 10 abstinence. Our results indicate that while correlated, both cessation self‐efficacy and current smoking behavior during a cessation attempt are important independent markers of ultimate cessation success.
Homeostatic impact of sulfite and hydrogen sulfide on cysteine catabolism
Authors: Kohl Joshua B , Mellis Anna‐Theresa , Schwarz Guenter 
Published: August 2018

Cysteine is one of the two key sulfur‐containing amino acids with important functions in redox homeostasis, protein functionality and metabolism. Cysteine is taken up by mammals via their diet and can also be derived from methionine via the transsulfuration pathway. The cellular concentration of cysteine is kept within a narrow range by controlling its synthesis and degradation. There are two pathways for the catabolism of cysteine leading to sulfate, taurine and thiosulfate as terminal products. The oxidative pathway produces taurine and sulfate, while the H2S pathway involves different enzymatic reactions leading to the formation and clearance of H2S, an important signalling molecule in mammals, resulting in thiosulfate and sulfate. Sulfite is a common intermediate in both catabolic pathways. Sulfite is considered as cytotoxic and produces neurotoxic S‐sulfonates. As a result, a deficiency in the terminal steps of cysteine or H2S catabolism leads to severe forms of encephalopathy with the accumulation of sulfite and H2S in the body. This review links the homeostatic regulation of both cysteine catabolic pathways to sulfite and H2S.Linked ArticlesThis article is part of a themed section on Chemical Biology of Reactive Sulfur Species.
