Evaluation of RANS and LES turbulence models for simulating a steady 2-D plane wall jet
Authors: Yan Zhitao , Zhong Yongli , Lin William E. , Savory Eric , You Yi 
Published: January 2018

PurposeThis paper examines various turbulence models for numerical simulation of a steady, two-dimensional (2-D) plane wall jet without co-flow using the commercial CFD software (ANSYS FLUENT 14.5). The purpose of this paper is to decide the most suitable and most economical method for steady, 2-D plane wall jet simulation.Design/methodology/approachSeven Reynolds-averaged Navier–Stokes (RANS) turbulence models were evaluated with respect to typical jet scaling parameters such as the jet half-height and the decay of maximum jet velocity, as well as coefficients from the law of the wall and for skin friction. Then, a plane wall jet generating from a rectangular slot of 1:6 aspect ratio located adjacent to the wall was investigated in a three-dimensional (3-D) model using large eddy simulation (LES) and the Stress-omega Reynolds stress model (SWRSM), with the results compared to experimental measurements.FindingsThe comparisons of these simulated flow characteristics indicated that the SWRSM was the best of the seven RANS models for simulating the turbulent wall jet. When scaled with outer variables, LES and SWRSM gave generally indistinguishable mean velocity profiles. However, SWRSM performed better for near-wall mean velocity profiles when scaled with inner variables. In general, the results show that LES performed reasonably well when predicting the Reynolds stresses.Originality/valueThe main contribution of this article is in determining the capabilities of different RANS turbulence closures and LES for the prediction of the 2-D steady wall jet flow to identify the best modelling approach.

Authors: Al Nahyan Moza Tahnoon , Hawas Yaser E. , Raza Mohsin , Aljassmi Hamad , Maraqa Munjed A. , Basheerudeen Basil , Mohammad Mohammad Sherif 
Published: January 2018

Purpose
The purpose of this paper is to present a framework to devise a system for ranking of traditional project delivery methods, regarding their suitability, against the varying levels of mega project attributes.

Design/methodology/approach
The proposed system employs input and output interfaces and a granular (fuzzy rule base) component for estimating the subjective levels of risks, opportunities, and constraints and then mapping them to a decision matrix. A questionnaire has been designed (using the SurveyGizmo® platform) to collect the perceptions of the various project stakeholders and use them. A total of 127 stakeholders completed the survey form in full.

Findings
The survey data were used to calibrate the fuzzy logic model of the granular component. The envisioned system computes, for each possible delivery method, an index that reflects the suitability (of the corresponding delivery method) on an ordinal scale.

Originality/value
The devised decision support system is likely to lessen the dependency of “accurate decision” on “the experience of the decision-makers.” It will also enable ranking the various project delivery methods based on the various project and stakeholder attributes that are likely to affect the project risks, opportunities and constraints.
Moderated influence of return frequency and resource commitment on information systems and reverse logistics strategic performance
Authors: Mahindroo Ankit , Samalia Harsh Vardhan , Verma Piyush 
Published: January 2018

PurposeReverse logistics (RL) is a strategic instrument across industries. The rapid evolution of online marketplaces has led to frequent product returns with variations across diversified businesses. These marketplaces have caused potential losses due to fraudulent returns, hence requiring a commitment of resources to RL. With information systems (IS) playing a role in improved supply chain performance, the purpose of this paper is to analyse the impact of a conceptualized IS framework on achieving RL strategic outcomes, under the individual moderating influence of resource commitment (RC) and return frequency.Design/methodology/approachData have been collected through a questionnaire from top to middle management executives managing the supply chain, logistics and IS. Moderated regression analysis was conducted on the collected sample using Hayes’ (2013) process modeling.FindingsThe study depicts that IS capability, IS for logistics, IS partnership quality and IS for value addition lead to RL strategic benefits. Also, return frequency and RC act as relatively strong moderators with a negative impact. When analyzed for the individual IS constructs, RC has a stronger moderating impact than return frequency.Practical implicationsThe IS usage framework can be used effectively by practitioners for enhancing strategic RL performances depending on variations in committed resources and return frequency for individual industries.Originality/valueThe study proposes an IS usage framework for achieving enhanced RL strategic outcomes and emphasizes on the moderating role played by RC and return frequency for producing the results.
Small enterprise development as a strategy to promote entrepreneurship in Bahir Dar city, Ethiopia
Authors: Melese Bekele 
Published: January 2018

Purpose
Entrepreneurship is a critical and necessary condition for sustained economic development. Different societies are more or less developed because they are endowed with more or less enterprising social groups. Entrepreneurship does not flourish in a social vacuum; its development is affected by cultural, socio-political and policy contexts in a given country or region. The purpose of this paper is to examine the culture of entrepreneurship in Ethiopia and analyse the role of micro and small enterprises development (MSED) as an approach towards promoting the culture of entrepreneurship by drawing empirical data from Bahir Dar, a fast-growing regional city in Ethiopia.

Design/methodology/approach
The data were collected through a survey of 136 small enterprises that were established under the MSED programme. Besides, an in-depth interview of key informants and document analysis methods were used to generate qualitative data for analysis.

Findings
Ethiopia remained an agrarian society to this date because of the lack of enterprise culture and entrepreneurial social groups which have been effectively prevented from growing by traditions that consider entrepreneurial activities ignoble and also by the anti-enterprise Marxist regime that prevailed until the early 1990s. The study also reveals that the MSED programme which is underway since the early 2000s has positive effects in promoting entrepreneurship.

Originality/value
The role of entrepreneurship and enterprise culture as an important factor of the development process has not been a concern in Ethiopian academic and policy-making circles. This study thus would help initiate further research and discussion on the issue.

Published: January 2018

Purpose
The purpose of this paper is to help in providing a better understanding on knowledge sharing amongst academics in higher education institutions (HEIs). The aim of this study is realized by profiling existing literature to understand the determinants of knowledge sharing, research trends, theories, and future research opportunities.

Design/methodology/approach
After carefully examining the extant literature and by utilizing relevant academic-based research databases, a total of 73 papers published in peer-reviewed journals over the last decade were reviewed and analyzed using well-established systematic literature review methodology.

Findings
The adopted systematic review revealed that there are limited contributions in understanding knowledge sharing in HEIs when compared with other sectors. The review provides a number of avenues for future research including technological, cultural, organizational, and behavioral aspects at different levels.

Practical implications
This study helps in offering a focal point to senior management in HEIs for realizing the requirements for developing appropriate strategies and programs to promote knowledge sharing among academics and consequently enhance their institutions’ performance.

Originality/value
This study utilized Jesson et al. (2011) in presenting a comprehensive systematic review of knowledge sharing specifically in the context of HEIs. This paper offers some theoretical and practical insights on what contributes toward understating the determinates affecting knowledge sharing practices among academics.
Unveiling the potentials of wine tourism: the way ahead for Limassol
Authors: Liasidou Sotiroula 
Published: January 2018

Purpose
The paper aims to bring together Limassol’s rich wine culture with the contemporary facet of its developing infrastructure and superstructure as a means through which to promote this city as a tourist destination. Additionally, to identify how Limassol can be experienced in relation to the wine culture based on the experience economy model of Pine and Gilmore (1999) Limassol is a seaside city in Cyprus that has developed extensively over the past few years, with a new infrastructure and superstructure that attracts foreign investments. Additionally, the city has a rich wine history with a particular emphasis on “Commanadaria wine” that originates in the twelfth century and is directly linked with the Richard the Lionheart king of England and the Third Crusade.

Design/methodology/approach
The methodology used was qualitative research, and in particular semi-structured interviews with professionals involved in the tourism industry in Limassol. A particular method was used to understand the ways in which wine history and culture permeate and influence the contemporary way of life in Limassol as a tourist destination.

Findings
The main results of this study suggest that Limassol has the potential to become an important destination that fulfils the requirements of the experience economy as put forth by Pine and Gilmore (1999). However, the main hindrance is the lack of a constructive tourism policy exclusive on wine tourism that will give a stronger identity to Limassol.

Originality/value
This research is original in nature because it considers a novice geographical area, Limassol, in the academic field. Thus, it is set as the cornerstone for further investigation on wine and tourism in Limassol. The managerial implications of the study are related to the engagement in wine culture, and in providing a unique identity to the city that can be promoted internationally.

Published: January 2018

Purpose
This paper aims to identify the relationship between organizational learning culture, psychological contract breach, work engagement, training simulation and transfer of training, to examine the effect of transfer of training on organizational citizenship behaviour and to determine the mediating effect of transfer of training on the relationship between organizational learning culture, psychological contract breach, work engagement and training simulation with organizational citizenship behaviour. This study investigated these relationships in the context of public sector organizations in Malaysia.

Design/methodology/approach
The data for this study were collected by using the purposive sampling from Malaysian Civil Defence Force or Angkatan Pertahanan Awam (APM) employees who attended a disaster preparedness training programme between March to May 2015. The questionnaire was the main tool for the data gathering. The data were analysed using structural equation modelling technique using AMOS 22 version software.

Findings
The findings showed that work engagement and training simulation are the factors that influence the transfer of training, and there is a positive effect of the transfer of training on the organizational citizenship behaviour. The result also demonstrated that the transfer of training is the mediator in the relationship between work engagement, training simulation and organizational citizenship behaviour.

Research limitations/implications
This study focuses on public sector areas which is Malaysia Civil Defense Force (APM). No interview session was conducted due to the time constraint in completing this study.

Originality/value
This study extends the existing understanding of factors that influence transfer of training and the effect of transfer of training on employees and organization. In other words, through the positive transfer of training, organizations not only attain positive returns on their training investment but also improve the performance and the work attitude of the organization’s employees.

Published: January 2018

PurposeThis study aims to examine the effect of socio-demographic, lifestyle and dietary factors on body composition among students from a private Lebanese University.Design/methodology/approachIn this cross-sectional study, socio-demographic and lifestyle variables were collected. Height and waist circumference were measured. Inbody 720 (Biospace, Korea) was used to assess body composition (percentage body fat [PBF], visceral fat area [VFA], skeletal muscle mass [SMM]) and fitness score. Diet was assessed using the MEDFICTS (meats, eggs, dairy, fried foods, fat in baked goods, convenience foods, fats added at the table and snacks) questionnaire.FindingsOut of 392 students, 3.1 per cent were underweight, 59 per cent were normal and 40 per cent were overweight and obese. In women,10.5 per cent adhered to the therapeutic lifestyle changes (TLC) compared to men (2.5 per cent), while 52.5 per cent of men needed dietary changes compared to 39.5 per cent of women, (p< 0.01). The most important predictors of PBF were being a woman, older age, lower fitness score and lower MEDFICTS score. The predictors of VFA were being a man, older age, less sleep time and lower fitness score. Being a man, smoking, higher fitness score and higher MEDFICTS score were predictors of SMM.Practical implicationsUpon university acceptance and as part of usual health screenings in universities, the authors’ study recommends screening of lifestyle and dietary habits of students, identifying students at risk and providing appropriate health interventions tailored to students’ needs.Originality/valueThis study is the first, in Lebanon, to assess the effects of sleep, stress, fitness and dietary habits on body composition of Lebanese university students.

Published: January 2018

Purpose
This study aims to design a set of sustainability indicators that is pertinent to cooperatives longevity. The primary goal of the cooperatives is towards meeting the economic progress of members while satisfying their socio-cultural interests and protecting the environment. As a sustainable and participatory form of business, cooperatives offer an alternative business model to social enterprises.

Design/methodology/approach
Using an extraction process analysis, this study examined and analyzed guidelines, indices, and framework on sustainability used by the public companies. The selected materials were analyzed using Atlas.ti software, whereby common indicators were divided into themes. The indicators were further scrutinized to suit the cooperatives identity and local regulations.

Findings
The results are presented as indicators for cooperatives sustainability that could serve as strategies and performance measurement. Promotion and expansion of cooperatives could be an important instrument for more than one billion people around the world involved in cooperatives either as members/customers, employees/participants, or both.

Originality/value
This work extends and complements the on-going efforts in uplifting the cooperatives sector as the third engine of economic growth in Malaysia. It contributes towards enriching the knowledge of the relationship between sustainable development and sustainability and its influence towards the cooperative sector. It may also provide the building blocks for future studies that could explore the usefulness of these indicators to other business setting having a similar objective like the cooperatives.
The effect of prosperity on international tourism expenditure
Authors: Sokhanvar Amin , Aghaei Iman , Aker Şule 
Published: January 2018

PurposeThis paper aims to investigate prosperity–international tourism expenditure nexus to discover the prosperity sub-indices which affect tourism expenditure.Design/methodology/approachUsing annual panel data for the sample period between 2009-2013 on 98 countries, this study implements a two-stage least squares estimation method with fixed effects specification in a panel regression analysis to find the relationships between international tourism expenditure and prosperity sub-indices.FindingsThe estimation results reveal a statistically significant relationship between the tourism expenditures of the citizens and prosperity, when prosperity is measured using its sub-indices, including Entrepreneurship and Opportunities, Government Efficiency, Education, Health, Safety and Security, Personal Freedom, Social Capital and Economy of the country. Education, Safety and Security and Health are the most significant factors which affect tourism expenditures of the country of origin.Practical implicationsTo decrease the money outflow, policymakers may have plans to improve health infrastructure and, at the same time, increase quality of education and access to education in the country. Tourism policies which do not consider these prosperity sub-indices as explanatory variables may make mistakes in controlling actual tourism expenditures.Originality/valueThe paper’s originality lies in using new independent variables (prosperity sub-indices) in estimating tourism expenditure by using an appropriate panel data approach that deals with endogeneity problems.
The Impact of Consulting Services on Audit Quality: An Experimental Approach
Authors: KOWALESKI ZACHARY T. , MAYHEW BRIAN W. , TEGELER AMY C. 
Published: January 2018

ABSTRACTWe use experimental markets to examine whether providing consulting services to a non‐audit client impacts audit quality. Our paper directly addresses concerns raised by the Public Company Accounting Oversight Board that the largest public accounting firms’ growth in their consulting practices threatens audit quality. We conduct an experiment proposed using a registration‐based editorial process. We compare a baseline where the auditor does not provide consulting services to conditions where auditors provide consulting to audit clients or where auditors only provide consulting services to non‐audit clients. Our unique design provides evidence on whether providing consulting to non‐audit clients strengthens the salience of a client‐cooperative social norm that reduces audit quality. We do not find differences in audit quality by condition in our planned analysis, however we find greater variation in audit quality in the conditions where auditors provide consulting services compared to the baseline. In unplanned analyses, our results suggest providing consulting services increases auditor cooperation with managers, increasing audit quality when managers prefer high audit quality and decreasing audit quality when managers prefer low audit quality.

Published: January 2018

AbstractArteriovenous fistula is the preferred option for vascular access in hemodialysis patients. The aim of this study was to assess different follow‐up methods for hemodialysis patients in our hemodialysis center in China. A cohort of 124 patients with stage 3 chronic kidney disease was recruited and double‐blind randomly assigned into two groups. Patients in Group A received phone calls to schedule their next consultation a week in advance. Patients in Group B scheduled their next appointment at the end of each visit. A total of 116 patients were included in the study and eight dropped out. Twenty‐seven patients (46.4%) in Group A and 13 patients (22.4%) in Group B had an AVF prior to hemodialysis (P = 0.006), and 44.8% of patients in Group A and 15.5% of patients in Group B were using AVFs at the initiation of dialysis (P = 0.003). Sixteen patients (27.6%) in Group A and 24 patients (41.3%) in Group B required central venous catheters due to acute on chronic kidney disease and 13 patients (22.4%) in Group A and 21 patients (36.2%) in Group B required central venous catheters due to patient‐related delays (P = 0.02). At the end of the study, seven patients in Group A died and 17 patients in Group B died (P = 0.027). The patients who received phone calls to schedule appointments in advance had a higher rate of arteriovenous fistulas prior to dialysis and at hemodialysis initiation had a reduced incidence of acute on chronic kidney disease and patient‐related delays, and had an improved prognosis.
