CSR perception and revisit intention: the roles of trust and commitment
Authors: Ahn Jiseon , Kwon Jookyung 
Published: July 2020

PurposeAlthough corporate social responsibility (CSR) is one of the essential marketing activities in the hotel industry, the effect of CSR perception on customer's revisit intention varies depending on mediators and contexts. Thus, this study aims to examine how hotel companies can effectively influence customers' patronage behaviors by leveraging overall customers' CSR perception, trust and commitment.Design/methodology/approachFor this purpose, an online survey is conducted among hotel customers in the USA. Partial least squares–structural equation modeling is utilized to analyze the collected data.FindingsThe results show that customers' perception toward CSR does not have a direct effect on customers' revisit intention. Interestingly, the authors find that customers' perception influences their revisit intention only via increasing trust and commitment. Also, trust appears to be highly critical for positive behavioral outcomes than commitment.Research limitations/implicationsThe limitations of the current research are that the different types of CSR activities and customers' demographics were not compared.Practical implicationsCustomers' revisit intention is created when hotel companies provide not only CSR initiatives but also customers' perceived connection with the hotel brand.Originality/valueTourism and hospitality companies have focused on CSR activities because CSR activities are influential strategies to attract customers who want meaningful, responsible and sustainable experiences. By applying the cognitive consistency theory, the results of this study indicate that hotel companies can successfully use CSR activities to develop customers' revisit intention by enhancing their relational value.
The surveillance of a supreme audit institution on related party transactions
Authors: Cesário Gustavo , Cardoso Ricardo Lopes , Aranha Renato Santos 
Published: July 2020

PurposeThis paper aims to analyse how the supreme audit institution (SAI) monitors related party transactions (RPTs) in the Brazilian public sector. It considers definitions and disclosure policies of RPTs by international accounting and auditing standards and their evolution since 1980.Design/methodology/approachBased on archival research on international standards and using an interpretive approach, the authors investigated definitions and disclosure policies. Using a topic model based on latent Dirichlet allocation, the authors performed a content analysis on over 59,000 SAI decisions to assess how the SAI monitors RPTs.FindingsThe SAI investigates nepotism (a kind of RPT) and conflicts of interest up to eight times more frequently than related parties. Brazilian laws prevent nepotism and conflicts of interest, but not RPTs in general. Indeed, Brazilian public-sector accounting standards have not converged towards IPSAS 20, and ISSAI 1550 does not adjust auditing procedures to suit the public sector.Research limitations/implicationsThe SAI follows a legalistic auditing approach, indicating a need for regulation of related public-sector parties to improve surveillance. In addition to Brazil, other code law countries might face similar circumstances.Originality/valuePublic-sector RPTs are an under-investigated field, calling for attention by academics and standard-setters. Text mining and latent Dirichlet allocation, while mature techniques, are underexplored in accounting and auditing studies. Additionally, the Python script created to analyse the audit reports is available at Mendeley Data and may be used to perform similar analyses with minor adaptations.
Maestros and mythologies: some lockdown reflections
Authors: Lizieri Colin 
Published: July 2020

PurposeThe paper reflects upon the tendency of participants in the commercial real estate markets to give excess status to individuals in decision-making and to hold beliefs that are at best weakly supported empirically.Design/methodology/approachThe paper is reflexive in nature, using experiential reflection to consider institutional processes in the real estate market. It is important to use “methodology” correctly and not as a synonym of “method”.FindingsUsing reflexive mode, the paper does not have “findings” as such: if the views expressed are accepted, then a research agenda to understand decision-making processes is implied.Research limitations/implicationsThe nature of reflection is that it follows from the writer's experiential processes and interpretations. The reader may come from a different stance. Broadly accepting the propositions points to the need for a contextual analysis of decision-making processes in private real estate and consideration of the implications of privileging individual idiosyncratic decisions over analytic procedures.Practical implicationsPrior research has demonstrated the lack of a back-testing culture in real estate that would allow empirical analysis of the consequences of “gut feel” decisions overriding modelled analysis; further, entrenched beliefs about the drivers of market performance might result in misallocation of resources.Social implicationsResource allocation in commercial real estate has important consequences for land use and urban and regional development.Originality/valueThe paper reflects the views and experience of the author based on over 30 years of research into commercial real estate.
Exploring the mediating role of work engagement between the linkages of job characteristics with organizational engagement and job satisfaction
Authors: Rai Alka , Maheshwari Sunil 
Published: July 2020

PurposeThe purpose of this study is to empirically test a hypothesized model establishing job characteristics as an antecedent of work engagement leading to job satisfaction and organizational engagement of employees working with public sector banks (PSBs) in India.Design/methodology/approachBased on responses to a survey questionnaire by a sample of 622 Scale I employees of Indian PSBs, the hypothesized mediation model was tested with SPSS macro (Preacher and Hayes, 2004).FindingsThe testing of hypotheses established that job characteristics positively influence work engagement, organizational engagement and job satisfaction. The full mediation by work engagement between the relationships of job characteristics with job satisfaction and organizational engagement is established after the testing of mediation hypotheses.Practical implicationsJobs of banks (especially in the public sector) are recommended to be enriched with more emphasis on offering employees with identifiable and significant tasks that have autonomy in decision-making and feedback. PSBs should also focus on developing a positive perception of employees toward job design, to increase their levels of job satisfaction and organizational engagement through engaging them with work.Originality/valueThe contribution of this study should be understood in many ways. First, the study has introduced work engagement as a mediator in the study model (between job characteristics and job satisfaction) replacing the three psychological conditions (i.e. experienced meaningfulness, experienced responsibility and knowledge of results) of job characteristics model. Further, the main contribution of this study is the exploration of the linkage between work engagement and organizational engagement. The relationship between these two forms of engagement (i.e. work and organization) has been very rarely investigated in the literature. Finally, this study has attempted to hypothesize a model proposing work engagement as a mediator between the job characteristics and organization engagement which does not seem to be studied so far.
Exploring the Bi-directional relationship between corporate social responsibility and financial performance in Indian context
Authors: Maqbool Shafat , Hurrah Shabir Ahmad 
Published: July 2020

PurposeThis study aims to investigate the relationship between corporate social responsibility (CSR) and financial performance from the bi-directional perspective.Design/methodology/approachThe final sample for this study are 79 companies listed in the national stock exchange for a period of eight-years (2008–2015). Random effect panel regression was performed to examine the possible link.FindingsThe result shows that CSR has a positive impact on the contemporaneous and future financial performance of the selected companies. Further, the study shows that only social dimension has a positive and significant impact on concurrent and future financial performance. The results further validate slack resource theory as lagged financial performance has a positive and significant impact on CSR.Practical implicationsThe strategic value of CSR indicates that it should be seen as a value-enhancing strategy, and therefore, incorporated with the broader corporate strategy of the company. Companies should not trade-off between CSR and financial performance, rather a strategic synchronization of CSR with corporate functioning is essential. This will pave a way to build a stakeholder-sense in the corporate entities.Originality/valueThe study comprehensively examines the relationship between CSR and financial performance from both “prospective” and “retrospective” framework. This bi-directional approach has received minimal attention in the Indian context.
MVO optimized hybrid FOFPID-LQG controller for load frequency control of an AC micro-grid system
Authors: Mishra Sonalika , Patel Suchismita , Prusty Ramesh Chandra , Panda Sidhartha 
Published: July 2020

Purpose
This paper aims to implement a maiden methodology for load frequency control of an AC multi micro-grid (MG) by using hybrid fractional order fuzzy PID (FOFPID) controller and linear quadratic Gaussian (LQG).

Design/methodology/approach
The multi MG system considered is consisting of photovoltaic, wind turbine and a synchronous generator. Different energy storage devices i.e. battery energy storage system and flywheel energy storage system are also integrated to the system. The renewable energy sources suffer from uncertainty and fluctuation from their nominal values, which results in fluctuation of system frequency. Inspired by this difficulty in MG control, this research paper proposes a hybridized FOFPID and LQG controller under random and stochastic environments. Again to confer viability of proposed controller its performances are compared with PID, fuzzy PID and fuzzy PID-LQG controllers. A comparative study among all implemented techniques i.e. proposed multi-verse optimization (MVO) algorithm, particle swarm optimization and genetic algorithm has been done to justify the supremacy of MVO algorithm. To check the robustness of the controller sensitivity analysis is done.

Findings
The merged concept of fractional calculus and state feedback theory is found to be efficient. The designed controller is found to be capable of rejecting the effect of disturbances present in the system.

Originality/value
From the study, the authors observed that the proposed hybrid FOPID and LQG controller is robust hence, there is no need to reset the controller parameters with a large change in network parameters.

Published: July 2020

AbstractBananas are rich in indigestible carbohydrates and are considered potential whole‐fruit prebiotics. To investigate banana‐induced changes in the composition of the human gut microbiota and the production of short chain fatty acids (SCFAs), ripe banana (Musa acuminata Colla, Degrees Brix: 22.6 ± 0.2° Bé), from Hainan, China, was powdered and fermented in vitro for 24 hr with the feces of six Chinese donors. The degradation of banana polysaccharides was observed in all six fecal samples. During in vitro fecal fermentation, banana polysaccharides were gradually degraded up to approximately 80%. The production of SCFAs was also measured. The addition of banana powder increased the concentrations of acetate, propionate, and butyrate, with the production of acetate being higher than that of propionate and butyrate. Changes in the human gut microbiota were assessed using high‐throughput sequencing of the 16S ribosomal RNA (rRNA) gene. The results indicated that banana powder significantly altered bacterial diversity, increasing the relative abundance of Bacteroides, while maintaining the proportion of Bifidobacterium in the feces. At the same time, banana powder also increased the proportion of Lactobacillus; however, a significant difference was not observed. In summary, banana powder can be utilized by specific bacteria in human intestines, providing data support for the study of the effects of banana powder on the human intestinal health.Practical ApplicationIn this study, in vitro batch fermentation was used to evaluate the effect of banana powder on the human intestinal microbial community, and the metabolized products of banana powder were determined. Our study showed that banana powder improved the human intestinal microbial flora and promoted the growth of Bifidobacterium and Bacteroides and could produce beneficial SCFAs (acetate, propionate, and butyrate). This study provided a theoretical basis for the use of banana powder as a potential prebiotic in production applications and our daily diet.

ObjectiveKetamine's effects on different dimensions of depressive symptomatology, including typical/melancholic and atypical depression, remain largely unknown. This study examined the effects of a single intravenous dose of ketamine on general depressive symptoms (measured using the Montgomery–Asberg Depression Rating Scale (MADRS), typical/melancholic symptoms (measured using the MADRS5), and atypical symptoms (measured using the Scale for Atypical Symptoms (SAS)).MethodsData from 68 participants with treatment‐resistant major depressive disorder (MDD) or bipolar depression were pooled from three separate, double‐blind, placebo‐controlled, crossover studies investigating ketamine's efficacy in depression. MDD participants were unmedicated; bipolar participants received therapeutic‐dose lithium or valproate. Clinical symptoms were collected preinfusion and up to 14 days postinfusion. Effect sizes were calculated for days 1 and 3 postinfusion. The primary measures of interest for this exploratory analysis were total MADRS, MADRS5, and SAS scores. Individual symptoms were also analyzed in an exploratory manner.ResultsScores improved significantly at Day 1 postinfusion (MADRS: Cohen's d = 0.64; MADRS5: Cohen's d = 0.61; SAS: Cohen's d = 0.41) and continued to be significantly improved over placebo at Day 3 (MADRS: Cohen's d = 0.49; MADRS5: Cohen's d = 0.43; SAS: Cohen's d = 0.39). Effect sizes were greater for typical/melancholic than atypical symptoms at Day 1 postinfusion.ConclusionKetamine appears to effectively treat both the typical/melancholic and atypical symptoms of depression, but may have early preferential effects for the former.

Published: July 2020

SummaryBackgroundProton pump inhibitors (PPIs) are the most commonly used first‐line therapy for patients with eosinophilic oesophagitis (EoE). However, many aspects related to PPIs in EoE are still unknown.AimsTo assess the effectiveness of PPI therapy for EoE in real‐world practice.MethodsThis cross‐sectional study collected data on PPI efficacy from the multicentre EoE CONNECT database. Clinical remission was defined as a decrease of ≥50% in dysphagia symptom score; histological remission was defined as a peak eosinophil count below 15 eosinophils per high‐power field. Factors associated with effectiveness of PPI therapy were identified by binary logistic regression multivariate analyses.ResultsOverall, 630 patients (76 children) received PPI as initial therapy (n = 600) or after failure to respond to other therapies (n = 30). PPI therapy achieved eosinophil density below 15 eosinophils per high‐power field in 48.8% and a decreased symptom score in 71.0% of patients. More EoE patients with an inflammatory rather than stricturing phenotype accomplished clinico‐histological remission after PPI therapy (OR 3.7; 95% CI, 1.4‐9.5); as well as those who prolonged treatment length from 8 to 12 weeks (OR 2.7; 95% CI, 1.3‐5.3). After achieving clinico‐histological remission of EoE, PPI dosage reduction was effectively maintained in 69.9% of patients, but tended to be less effective among those with a stricturing phenotype.ConclusionsInflammatory EoE phenotype and treatment duration up to 12 weeks correlated with greater chance for inducing remission of EoE. A stricturing phenotype decreased response rates to PPI therapy both initially and in the long term.
Factors promoting the use of virtual worlds in educational settings
Authors: Shonfeld Miri , Greenstein Yoram 
Published: July 2020

AbstractThis paper focuses on student attitudes about using a virtual world (VW) learning platform. VWs allow students to meet via avatars and experience events that simulate real social experiences. It can also enhance student motivation, learning and collaboration. However, studies have reported that many students and teachers find VW difficult to use, and thus, do not adopt it. The current study sought to examine preservice teachers' experiences in VW in a multiple‐college course. The aims of the study were to focus on the possible difficulties and supporting factors affecting the present use of VW and identify factors affecting the future use of VW. Ninety‐nine Jewish and Arab students from eight teachers' colleges in Israel who participated in a VW learning experience completed an online questionnaire, which included items relating to their experience with computer games, difficulties and level of satisfaction with the course. Computer‐game experience, cultural background, technical difficulties and satisfaction with class management predicted the intention to use VW in the future. Possible practical and theoretical implications are discussed.
Waging Class Struggle With Plants: Intra‐class differentiation and greening labor in a public housing project in Rio de Janeiro, Brazil
Authors: Burdick John 
Published: July 2020

AbstractIntra‐class differentiation needs to be brought back into the analysis of gentrification. In this article I argue that in the context of gentrifying pressures, greenspaces are an important site of struggle between segments of the working class. By paying attention to how different clusters of low‐income residents in a housing project in Rio de Janeiro deploy plants, we gain insight into differently‐situated working‐class life projects, and into how neoliberal capital exacerbates competition between them. Through the lens of greening labor we discover a working class that includes not just victims of the forces of gentrification, but active resistors and savvy collaborators with those forces.
Plant virus infection modifies plant pigment and manipulates the host preference behavior of an insect vector
Authors: Moeini Pedram , Afsharifar Alireza , Homayoonzadeh Mohammad , Hopkins Richard J. 
Published: July 2020

AbstractInsect‐borne plant viruses may modify the phenotype of their host plants and thus influence the responses of insect vectors. When a plant virus modifies host preference behavior of a vector, it can be expected to influence the rate of virus transmission. In this study, we examined the effect of Maize Iranian mosaic virus (MIMV) infection on host preference behavior of the nymphs and adults of its vector, the small brown planthopper, Laodelphax striatellus Fallén (Hemiptera: Delphacidae), feeding on barley plants (Hordeum vulgare L., Poaceae). We found that both viruliferous nymphs and adults significantly preferred healthy plants, whereas non‐viruliferous planthoppers preferred virus‐infected barley. Further investigations revealed significant reductions in the chlorophyll and carotenoid contents of infected barley leaves. Based on these results, a possible association between insect host preferences and the pigment contents of the plants was observed. In summary, we suggest that host preference of L. striatellus could be affected by the propagative plant virus, possibly through association of this modification with some phenotypic traits of infected plants. These effects may have a critical impact on MIMV transmission rate, with significant implications for the development of virus epidemics.
Establishment, spread, and impact of an invasive planthopper on its invasive host plant: Prokelisia marginata (Homoptera: Delphacidae) exploiting Spartina anglica (Poales: Poaceae) in Britain
Authors: Harkin Claire , Stewart Alan J. A. 
Published: July 2020

1. Since its recent arrival in Britain, the planthopper Prokelisia marginata has spread widely around saltmarshes on the east and south coast of England and south Wales, feeding on Common Cordgrass, Spartina anglica, itself an invasive non‐native species.2. Results suggest that P. marginata populations in Britain benefit from a degree of natural enemy release. No evidence of parasitism was found in over 71 000 eggs, nymphs, and adults inspected. The only potential natural enemy control was suggested by a positive correlation between the densities of planthoppers and generalist spiders.3. Experimental exposure under both glasshouse and field conditions to typical field densities of planthoppers resulted in significant negative effects on a number of host plant performance metrics.4. Spartina anglica is important for stabilising estuarine sediments and has been deliberately planted for this purpose in the past. Its weakening as a result of heavy planthopper herbivory could have serious consequences for the long‐term stability of Britain's vulnerable saltmarsh habitats.
Towards Europeanisation through the proportionality test? The impact of free movement law on medical professional discipline
Authors: van Leeuwen Barend 
Published: July 2020

AbstractMedical doctors can exercise their free movement rights to escape the control of professional regulation at the national level. This “darker side” of free movement of doctors has received a lot of attention. This article will show that the free movement provisions play an increasingly important role in medical disciplinary cases. The application of free movement law can make a positive contribution to the protection of patient safety. However, disciplinary tribunals are unfamiliar with the structure of arguments based on the free movement provisions. While the case law on free movement of patients has encouraged a process of internationalisation of medical standards, free movement of doctors has not yet led to a similar process of Europeanisation of medical professional rules. Nevertheless, the proportionality test requires that disciplinary tribunals engage in a process of comparison between their own rules and the rules in other Member States.
