Unsteady conjugate heat transfer with combined effects of MHD and moving conductive elliptic object in CNT-water nanofluid with ventilation ports
Authors: Selimefendigil Fatih , Öztop Hakan F. 
Published: May 2021

Purpose
The purpose of this paper is to analyze the unsteady conjugate mixed convective heat transfer characteristics in a vented porous cavity under the combined effects of moving conductive elliptic object and magnetic field.

Design/methodology/approach
The finite element method and arbitrary Lagrangian-Eulerian (ALE), impacts of Reynolds number, Hartmann number, aspect ratio of the conductive ellipse and moving speed of the object on the hydro-thermal performance are analyzed.

Findings
It was observed that the dynamic characteristics of the local and average Nu number of each hot wall are different. Magnetic field strength increment resulted in the enhancement of average Nu number for bot steady and transient case while the optimum case for best hydro-thermal performance is achieved for highest Ha number and non-dimensional time of 10. Higher value of average Nu and lower pressure coefficient are achieved for aspect ratio of 4 and non-dimensional time of 10. When the moving velocity of the conductive ellipse is considered, 42% enhancement in the average Nu is obtained at non-dimensional time of 20 and object velocity equals to 0.012 times entering fluid velocity in the negative y direction while the pressure coefficient is higher. The moving object is used as a useful tool to control the dynamic features of heat transfer in a vented cavity.

Originality/value
The present method of convective heat transfer control inside a vented cavity with a moving elliptic object is novel and can be used as an effective tool with magnetic field effects owing to diverse use of convection in cavities with vented ports in many practical thermal engineering systems.
Determinants of multi-destination travel in Vietnam: a rational choice perspective
Authors: Do Hao Thi Kim , Hoang Dung Phuong , Pham Thuy Thu 
Published: May 2021

PurposeThis paper aims to examine the factors affecting travelers’ decision to select more than one destination in their trips. Drawn from the rational choice theory, this study posits that the selection of multi-destination tours, as a rational choice, is determined by the travelers’ perception of costs and benefits associated with that choice.Design/methodology/approachThe conceptual model was developed from both an exploratory research with in-depth interview and the literature. A logistic regression model linking four explanatory variables representing perceived benefits and costs of multi-destination option with travelers’ choice of multi-destination trips. The conceptual model is controlled for diversity of travel purposes; tour group size; type of travel arrangement and travelers’ demographic characteristics while the research context of multi-destination travel within Phu Yen – Dak Lak – Gia Lai – Binh Dinh helps control for the characteristics of the destination set (spatial proximity and traffic convenience). The conceptual model was tested based on data collected from 1,361 Vietnamese travelers who have ever visited at least one of the four provinces.FindingsThis study finds that perceived benefits in terms of diversifying tourism experiences and perceived costs of traveling in multiple places compared to taking single trips represent the most significant drivers for tourists’ selection of multi-destination tours. In addition, the diversity of travel purposes and tour group size have a positive and significant impact on the demand for traveling more than one destination in a trip. Moreover, the richer, older and married travelers have a significantly higher tendency to select multi-destination packages.Practical implicationsThe research findings provide important strategic implications for promoting multi-destination trips, thereby, maximizing economic benefits from tourism.Originality/valueWhile multi-destination travel patterns have been examined empirically in individual studies sporadically without a common theoretical background, this research makes some progress on this front by using the rational choice theory to connect the relative contributions of those factors to the travelers’ choice of multi-destination trips. Specifically, this study provides a new perspective in explaining the selection of multi-destination trips – from tourists’ perceptions about costs and benefits associated with that choice.
Empirical identification of skills gaps between chief information officer supply and demand: a resource-based view using machine learning
Authors: Barnes Stuart , Rutter Richard N. , La Paz Ariel I. , Scornavacca Eusebio 
Published: May 2021

PurposeThe role of emerging digital technologies is of growing strategic importance as it provides significant competitive advantage to organisations. The chief information officer (CIO) plays a pivotal role in facilitating the process of digital transformation. Whilst demand continues to increase, the supply of suitably qualified applicants is lacking, with many companies forced to choose information technology (IT) or marketing specialists instead. This research seeks to analyse the organisational capabilities required and the level of fit within the industry between CIO requirements and appointments via the resource-based view.Design/methodology/approachJob postings and CIO curriculum vitae were collected and analysed through the lens of organisational capability theory using the machine learning method of Latent Dirichlet Allocation (LDA).FindingsThis research identifies gaps between the capabilities demanded by organisations and supplied by CIOs. In particular, soft, general, non-specific capabilities are over-supplied, while rarer specific skills, qualifications and experience are under-supplied.Practical implicationsThe research is useful for practitioners (e.g. potential CIO candidates) to understand current market requirements and for companies aiming to develop internal training that meet present and future skill gaps. It also could be useful for professional organisations (e.g. CIO Forum) to validate the need to develop mentoring schemes that help meet such high demand and relative undersupply of qualified CIOs.Originality/valueBy applying LDA, the paper provides a new research method and process for identifying competence requirements and gaps as well as ascertaining job fit. This approach may be helpful to other domains of research in the process of identifying specific competences required by organisations for particular roles as well as to understand the level of fit between such requirements and a potential pool of applicants. Further, the study provides unique insight into the current supply and demand for the role of CIO through the lens of resource-based view (RBV). This provides a contribution to the stream of information systems (IS) research focused on understanding CIO archetypes and how individual capabilities provide value to companies.
Public sector fraud: the Malaysian perspective
Authors: Zahari Afzal Izzaz , Said Jamaliah , Muhamad Nurisyal 
Published: May 2021

Purpose
This paper aims to explore and compare the perception of public sector employees on fraud and associated fraud behaviours.

Design/methodology/approach
The population of this study comprised 44 managers from the Malaysian Federal government departments. The analysis was based on an open-response questionnaire using data-driven thematic analysis. This was based on the context and latent content of the respondents. The items in the questionnaire examined the perceived definition, actions and experience of corruption in their departments.

Findings
The findings revealed that respondents acknowledged that bribery as one of the central element of fraud. They recognise fraudulent behaviour and practice in their organisation together with sharing these experiences in the study. Common results indicate that leaders play a major role in shaping the organisation as they present themselves as a model to the mployees. From the human resource perspective, having multiple side businesses while being in employed in the government sector would heavily impact performance and accountability.

Research limitations/implications
Fraud is observed as a practice that needs to be addressed to improve government efficiency. The uniqueness was that the respondents acknowledged the existence of fraud and its implications through the activities of bribery, abuse of power and giving out favours. There is a need for organisations to focus on transparency and value to mitigate fraud.

Practical implications
This paper contributes towards the continuous effort in expanding fraud literature and human behaviour. The data obtained was distinctive in terms of the perspective of a developing economy and such fraud information and responses are different as compared to developed economies.

Originality/value
The empirical study of the public sector organisations enables important contribution towards effective public governance and administration. The results have important implications for preparing functional strategic management and controls for the public sector.
The perceived impact of the KAM reforms on audit reports, audit quality and auditor work practices: stakeholders’ perspectives
Authors: Nguyen Lan Anh , Kend Michael 
Published: May 2021

PurposeThe purpose of this study is to understand how the new reforms related to key audit matters (KAM) disclosures in Australia may have impacted audit quality by eliciting the perceptions of key stakeholders in the audit and assurance services market.Design/methodology/approachThe study uses a qualitative approach and New Institutional Sociology (NIS) to explain how auditors have responded to the KAM reforms. Interviews were conducted with 20 individuals representing identified groups of stakeholders in the market for audit and assurance services in Australia.FindingsThe study finds there is little consensus between some stakeholder groups on whether the KAM reforms may have improved audit quality, based on the perceptions shared. The findings conveyed that the auditors and regulators, standard setters acknowledge that KAM disclosures are either costly and/or time-consuming to implement. The Big Four auditors indicate these reforms led to changes mainly around internal consultations and independent reviews, whereas the non-Big Four auditors highlighted increased interactions with audit clients.Originality/valueThis is one of the first studies to examine the perceived post-implementation impacts on audit quality of the KAM reforms (ISA 701) after the initial two years of implementation and how auditors have responded, explored through the lens of institutional logic.
Sustainable tourism consumer: socio-demographic, psychographic and behavioral characteristics
Authors: Tasci Asli D.A. , Fyall Alan , Woosnam Kyle Maurice 
Published: May 2021

PurposeThis study aims to uncover socio-demographic, psychographic and behavioral characteristics of sustainable consumers as a means to advance the demand for sustainability practices by the tourism and hospitality industry. Socio-demographic and psychographic variables were tested for their influence on an individual’s self-assessment as a sustainable consumer, which was then tested for its influence on behavioral outcomes in the form of environmental and social sustainability concerns, objects of sustainability concerns, subjects considered responsible for sustainability and tourism choicevis-à-vismass vs alternative forms of tourism.Design/methodology/approachBecause of the paucity of a well-established and robust theory on the characteristics of sustainable consumers, both content analysis of the literature and quantitative analysis of survey data were used to identify the socio-demographic, psychographic and behavioral characteristics of consumers. Plausible variables identified in the literature were filtered through principal component analysis and ordinary least squares regression analysis to fine-tune the variables a priori to develop a suitable model, which was subjected to partial least squares-structural equation modeling to further trim variables a posteriori by testing their reliability and validity.FindingsUnderstanding who sustainable consumers are and what they are likely to believe and do is imperative for increasing sustainable practices by the industry. The study shows that people who consider themselves to be sustainable consumers are likely to have higher levels of ethical views, be more feminine and more liberal in personality, demonstrate concern with environmental and social sustainability issues, consider all pertinent parties responsible for sustainability and chose alternative forms of tourism over mass tourism. The study implies that general American consumers have the potential to buy into sustainability practices.Originality/valueDespite researchers’ sporadic attempts to describe different characteristics of sustainable consumers and sustainable tourism consumers, past research has not substantiated a comprehensive description of who is a sustainable consumer in terms of socio-demographics, psychographics and behavioral characteristics. The literature on sustainable consumer characteristics is scarce and atheoretical; thus, the current study sets the stage for the development of this area of work across all sectors of the global tourism and hospitality industry. The model test results provide a clear profile of sustainable tourism consumers in socio-demographic, psychographic and behavioral domains for the industry to respond to.
Positive interactions between an exotic invader and moss biocrusts vary across life stage and correspond with the effect of water pulses on soil nitrogen
Authors: Slate Mandy L. , McLeod Morgan Luce , Callaway Ragan M. 
Published: May 2021

Abstract

The size and frequency of resource pulses can affect plant interactions and increase the abundance of invasive species relative to native species. We examined resource pulses generated during the desiccation and rehydration of communities of native biological soil crust (biocrust)‐forming mosses, in the context of positive associations between biocrusts and the invasive forb, Centaurea stoebe.

We surveyed Centaurea and biocrust cover and evaluated how interactions among Centaurea, biocrusts and water pulses influenced plant biomass and soil nitrogen in a field experiment. Centaurea seedling and biocrust interactions were also compared in a greenhouse experiment to evaluate differences related to life stage.

In field surveys, Centaurea and biocrusts were positively associated. Across water pulse treatments, biocrust biomass decreased when Centaurea was removed, indicating that Centaurea facilitated biocrusts. Biocrusts did not affect adult Centaurea in the field, but Centaurea seedling biomass was greater when grown with biocrusts in the greenhouse. Water pulses did not affect plant biomass, but interactions between Centaurea and biocrusts corresponded with variation in the effect of water pulses on soil nitrogen which were not evident when Centaurea or biocrusts were grown alone. Twenty‐four hours after large water pulses were added, soil was nine times higher in plots where biocrusts and Centaurea co‐occurred compared with small water pulse plots. In these same plots, soil tended to be lower at the end of the experiment.

These results highlight positive interactions between an invasive exotic forb and native moss biocrust. Water pulses influenced soil nitrogen availability when both plants co‐occurred, but did not affect plant biomass, suggesting that resource pulses and species interactions can interact to affect ecosystem processes.

ObjectiveTo describe the immediate impact of the COVID‐19 pandemic on cervical screening, colposcopy and treatment volumes in Ontario, Canada.DesignPopulation‐based retrospective observational study.SettingOntario, Canada.PopulationPeople with a cervix age of 21–69 years who completed at least one cervical screening cytology test, colposcopy or treatment procedure for cervical dysplasia between January 2019 and August 2020.MethodsAdministrative databases were used to compare cervical screening cytology, colposcopy and treatment procedure volumes before (historical comparator) and during the first 6 months of the COVID‐19 pandemic (March–August 2020).Main outcome measuresChanges in cervical screening cytology, colposcopy and treatment volumes; individuals with high‐grade cytology awaiting colposcopy.ResultsDuring the first 6 months of the COVID‐19 pandemic, the monthly average number of cervical screening cytology tests, colposcopies and treatments decreased by 63.8% (range: −92.3 to −41.0%), 39.7% (range: −75.1 to −14.3%) and 31.1% (range: −43.5 to −23.6%), respectively, when compared with the corresponding months in 2019. Between March and August 2020, on average 292 (−51.0%) fewer high‐grade cytological abnormalities were detected through screening each month. As of August 2020, 1159 (29.2%) individuals with high‐grade screening cytology were awaiting follow‐up colposcopy.ConclusionsThe COVID‐19 pandemic has had a substantial impact on key cervical screening and follow‐up services in Ontario. As the pandemic continues, ongoing monitoring of service utilisation to inform system response and recovery is required. Future efforts to understand the impact of COVID‐19‐related disruptions on cervical cancer outcomes will be needed.Tweetable abstractCOVID‐19 has had a substantial impact on cervical screening and follow‐up services in Ontario, Canada.

AbstractObjectiveWestern Sydney University has implemented a rural interprofessional learning programme to promote collaborative care approaches to enhance cross‐discipline communications, improve knowledge and clarity of roles and improve patient care and outcomes.DesignRural interprofessinal learning is an interprofessional educational approach, consisting of simulations of complex health events. Simulation methodology frames the study with a focus on human interaction. A mixed‐methods evaluation has been conducted, incorporating pre‐ and post‐ event participant surveys along with semi‐structured focus groups.SettingSimulations are conducted in the rural setting, including community settings, working farms and rural hospitals.Main Outcome MeasuresReflexive thematic analysis was used to identify themes measuring students' perceptions of interdisciplinary care, knowlede of other health discipline roles and skills and how they believe the exercise will influence their future practice. Facilitator feedback regarding the efficacy of the simulations was also recorded and analysed using reflexive thematic analysis.ParticipantsCare of simulated patient(s)/bystander(s) is primarily provided by paramedicine, nursing and medical students; however, increasing interest has expanded the programme to include students from a range of allied health professions. Simulations are facilitated by a multidisciplinary team of experienced practitioners and specialists.InterventionFour rural interprofessional learning events have been held.Results120 students have participated in the evaluation. Findings include increased understanding of the contributions of other disciplines in enhancing patient care, team approaches, cross‐discipline communication and a need to engage in collaborative care in future practice.ConclusionCreating a collaborative learning environment creates a culture of multidisciplinary care, enhancing patient care and improving outcomes. The rural interprofessional learning model is an effective interprofessional educational approach, which can be repeated, refined and improved for continual professional development.
Three‐phase four‐dimensional computed tomography as a first‐line investigation in primary hyperparathyroidism
Authors: Leong David , Ng Katrina , Boeddinghaus Rudolf , Lisewski Dean 
Published: May 2021

AbstractIntroductionParathyroid computed tomography using multiple phases (four‐dimensional computed tomography (4DCT) for parathyroid localization was first described in 2006. Since its inception, there has been variable uptake of this technique due to inconsistency of results between institutions and perceived higher radiation dose than technetium‐99 sestamibi scans (MIBI). 4DCT has been the primary imaging modality for parathyroid localization at our institution since 2013.MethodsA retrospective study of surgically managed patients with primary hyperparathyroidism who had preoperative localization with 4DCT from 2013–2018 was performed.ResultsA total of 353 patients were included for analysis. The positive predictive value (PPV) of our three‐phase 4DCT protocol was 93.3%, sensitivity (localized) 85.2% with a 5.8% false‐positive rate and 13.9% false‐negative (non‐localizing) rate when reported by a head and neck radiologist (HNR). Calculated effective dose varied from 4.5 to 8.9mSV. On multivariable logistic regression, reporting by an experienced HNR (P < 0.001) and gland weight > 200 mg (P = 0.002) were significant for higher accuracy, lower false positives and false negatives.ConclusionA first‐line three‐phase 4DCT protocol for primary hyperparathyroidism is an accurate technique providing precise anatomical localization of abnormal parathyroid glands, particularly when performed by a specialist HNR. In our practise, it provides the best rate of detection and superior anatomical localization needed for minimally invasive parathyroid surgery, compared to other commonly used localization techniques. It also avoids the need for four gland exploration in the majority of patients with primary hyperparathyroidism.
