Effects of cavity and heat source aspect ratios on natural convection of a nanofluid in a C-shaped cavity using Lattice Boltzmann method
Authors: Izadi Mohsen , Mohebbi Rasul , Chamkha A. , Pop Ioan 
Published: October 2018

Purpose
The purpose of this paper is to consider natural convection of a nanofluid inside of a C-shaped cavity using Lattice Boltzmann method (LBM).

Design/methodology/approach
Effects of some geometry and flow parameters consisting of the aspect ratio of the cavity, aspect ratio of the heat source; Rayleigh number (Ra = 103 − 106) have been investigated. The validity of the method is checked by comparing the present results with ones from the previously published work.

Findings
The results demonstrate that for Ra = 103, the aspect ratio of the heat source has more influence on the average Nusselt number in contrast to the case of Ra = 106. Contrary to the fact that the average Nusselt number increases non-linearly more than twice because of the increase of the aspect ratio of the enclosure at Ra = 103, the average Nusselt number has a linear relation with the aspect ratio for of Ra = 106. Therefore, upon increasing the Rayleigh number, the efficiency of the aspect ratio of the cavity on the thermal convection, gradually diminishes.

Originality/value
The authors believe that all the results, both numerical and asymptotic, are original and have not been published elsewhere.

Authors: Zargartalebi H. , Ghalambaz M. , Chamkha A. , Pop Ioan , Nezhad Amir Sanati 
Published: October 2018

Purpose
A numerical model of an unsteady laminar free convection flow and heat transfer is studied in a cavity that comprises a vertical flexible thin partition.

Design/methodology/approach
The left and right vertical boundaries are isothermal, while the horizontal boundaries are insulated. Moreover, the thin partition, placed in the geometric centerline of the enclosure, is considered to be hyper elastic and diathermal. Galerkin finite-element methods, the system of partial differential equations along with the appropriate boundary conditions are transformed to a weak form through the fluid-structure interaction and solved numerically.

Findings
The heat transfer characteristics of the enclosure with rigid and flexible partitions are compared. The effect of Rayleigh number and Young’s modulus on the maximum nondimensional stress and final deformed shape of the membrane is addressed.

Originality/value
Incorporation of vertical thin flexible membrane in middle of a cavity has numerous industrial applications, and it could noticeably affect the heat and mass transfer in the enclosure.

Authors: Pelsmakers Sofie , Vereecken Evy , Airaksinen Miimu , Elwell Cliff C.A. 
Published: October 2018

PurposeMillions of properties have suspended timber ground floors globally, with around ten million in the UK alone. However, it is unknown what the floor void conditions are, nor the effect of insulating such floors. Upgrading floors changes the void conditions, which might increase or decrease moisture build-up and mould and fungal growth. The purpose of this paper is to provide a review of the current global evidence and present the results ofin situmonitoring of 15 UK floor voids.Design/methodology/approachAn extensive literature review on the moisture behaviour in both uninsulated and insulated suspended timber crawl spaces is supplemented with primary data of a monitoring campaign during different periods between 2012 and 2015. Air temperature and relative humidity sensors were placed in different floor void locations. Where possible, crawl spaces were visually inspected.FindingsComparison of void conditions to mould growth thresholds highlights that a large number of monitored floor voids might exceed the critical ranges for mould growth, leading to potential occupant health impacts if mould spores transfer into living spaces above. A direct comparison could not be made between insulated and uninsulated floors in the sample due to non-random sampling and because the insulated floors included historically damp floors. The study also highlighted that long-term monitoring over all seasons and high-resolution monitoring and inspection are required; conditions in one location are not representative of conditions in other locations.Originality/valueThis study presents the largest UK sample of monitored floors, evaluated using a review of current evidence and comparison with literature thresholds.
Development of the Persian patient satisfaction questionnaire
Authors: Nouri Mahdi , Ghaffarifar Saeideh , Sadeghi-Bazargani Homayoun 
Published: October 2018

Purpose
The purpose of this paper is to explore the validity and reliability of the Persian version of the patient satisfaction questionnaire (PVPSQ). The study addressed the communication skills section of the PSQ specifically.

Design/methodology/approach
This cross-sectional study was conducted in 2015 to determine the validity and reliability of the Persian version of the patient satisfaction questionnaire (PSQ). In total, 538 patients (ten in pilot, 488 in tests, 40 in retest), 14 experts and 198 residents participated. The items’ impact score, content validity index, and content validity ratio were calculated. Construct validity and reliability of the scale were examined with exploratory factor analysis, Cronbach’s α, and the Intraclass correlation coefficient (ICC), respectively.

Findings
The questionnaire demonstrated a content validity index=0.94, content validity ratio=0.84, impact score=4.61, Cronbach’s α=0.93 and ICC=0.513 (p<0.00). A single factor was found in the eigenvalue distribution of the PSQ that predicted approximately 93 percent of the variance.

Practical implications
The results of this study will permit researchers in all Persian-speaking countries to use a valid and reliable Persian version of the PSQ to evaluate patients’ satisfaction with residents’ communication skills.

Originality/value
There were a few Persian questionnaires to assess patient satisfaction with physicians’ communication skills, but their psychometric properties had not been reported until the time of this study. By using the PVPSQ, both researchers at Iranian universities of medical sciences and researchers in other Persian-speaking countries can assess residents’ communication skills from the patient’s perspective more reliably.
Does skewness help in better investment decision making?
Authors: Kumar Satish 
Published: October 2018

Purpose
The purpose of this paper is to examine the significance of skewness in maximizing the investor utility using the daily data for eight sectors listed on the National Stock Exchange of India.

Design/methodology/approach
The analysis is carried out in three different steps. In the first part, the author analyzes the monthly stock returns and the important financial ratios – price-to-book (PB) ratio, price-earnings (PE) ratio and dividend yield (DY). Second, the author tests the sector-wise return predictability using Westerlund and Narayan (2012) flexible generalized least squares estimator. Third, the author compares the mean–variance–skewness (MVS) utility function with the mean–variance (MV) utility function.

Findings
The author forecasts the sectoral stock returns using three financial ratios – PB ratio, PE ratio and DY – as predictors. The results indicate that sectoral stock returns are significantly predicted by these financial ratios. The author then formulates trading strategies by including skewness in the utility function and finds that the investor utility is high when the utility function includes skewness as opposed to when the skewness is excluded.

Originality/value
The author extends the MV utility function to the MVS utility function and shows that the Indian stock market is more profitable when the investor uses a MVS utility function which highlights the main contribution to the literature.

Authors: Jones Jocelyn , Wilson Mandy , Sullivan Elizabeth , Atkinson Lynn , Gilles Marisa , Simpson Paul L. , Baldry Eileen , Butler Tony 
Published: October 2018

PurposeThe rise in the incarceration of Aboriginal and Torres Strait Islander mothers is a major public health issue with multiple sequelae for Aboriginal children and the cohesiveness of Aboriginal communities. The purpose of this paper is to review the available literature relating to Australian Aboriginal women prisoners’ experiences of being a mother.Design/methodology/approachThe literature search covered bibliographic databases from criminology, sociology and anthropology, and Australian history. The authors review the literature on: traditional and contemporary Aboriginal mothering roles, values and practices; historical accounts of the impacts of white settlement of Australia and subsequent Aboriginal affairs policies and practices; and women’s and mothers’ experiences of imprisonment.FindingsThe review found that the cultural experiences of mothering are unique to Aboriginal mothers and contrasted to non-Aboriginal concepts. The ways that incarceration of Aboriginal mothers disrupts child rearing practices within the cultural kinship system are identified.Practical implicationsAboriginal women have unique circumstances relevant to the concept of motherhood that need to be understood to develop culturally relevant policy and programs. The burden of disease and cycle of incarceration within Aboriginal families can be addressed by improving health outcomes for incarcerated Aboriginal mothers and female carers.Originality/valueTo the authors’ knowledge, this is the first literature review on Australian Aboriginal women prisoners’ experiences of being a mother.
Effects of strategic information systems on competitive strategy and performance
Authors: Yoshikuni Adilson Carlos , Albertin Alberto Luiz 
Published: October 2018

Purpose
This study argues that strategic information systems (SISs) are necessary for organizations’ survival and corporate performance in turbulent economic environments. Applying Miles and Snow’s strategy typology, the purpose of this paper is to explore how SIS supports business strategy and corporate performance.

Design/methodology/approach
This study uses quantitative survey data from 389 Brazilian companies during economic crises and analyzes them using structural equation modeling.

Findings
There is strong evidence that SIS promotes capacity and flexibility to create competitive strategies in response to environmental changes. SIS significantly and positively predicts firms’ use of prospector strategies, reducing the need to sacrifice efficiency for innovation. SIS can predict corporate performance more strongly than firms’ strategic orientations can.

Practical implications
The results provide organizations insights on how SIS enables strategic planning processes to create competitive strategy and improve performance during economic turbulence.

Originality/value
This research demonstrates SIS’s positive effects during economic turbulence on competitive strategy and performance, revealing that corporate performance is influenced more by SIS (strategic process) than strategic orientation (content). Hence, this study fills a research gap in the information systems strategy literature by contributing new insights about SIS.
A transformed fixed effect stochastic frontier approach for productivity evaluation in Indian electricity sector
Authors: Khetrapal Pavan 
Published: October 2018

PurposeThe purpose of this paper is to evaluate the utility-level productivity changes in Indian electricity sector during a period that witnessed structural reforms through several landmark regulatory changes.Design/methodology/approachA transformed fixed-effect stochastic frontier panel approach accounting for time-invariant unobserved heterogeneity is employed to evaluate the productivity changes, and the inefficiency level in 98 utilities spanning over the years 2001–2010. A flexible translog production model is modeled and estimated, and decomposition of productivity into components of changes in efficiency, scale technology and price effect is computed.FindingsThe empirical findings obtained from the present study suggest that the utility-level productivity in Indian electricity sector has generally declined during the observed period of 2001–2010 specifically after the implementation of Electricity Act 2003. Also, it is estimated that the state-level un-bundling of the electricity sector is not significantly associated with utility-level efficiency change. Furthermore, efficiency improvements attributable to increased competition are observed only in the case of smaller gas-based generating utilities.Originality/valueEarlier studies on the productivity evaluation of Indian electricity industry have applied the non-parametric data envelopment analysis approach, which has several limitations. The novelty of the paper lies in the fact that this paper is one of the first attempts that implement transformed fixed-effect stochastic frontier panel approach and thus disentangle unobserved heterogeneity from inefficiency. Furthermore, it is the only paper that analyzes 98 utilities (51 generating utilities, 38 transmission and distribution licensees and 9 vertically integrated utilities) in a single framework during the period 2001–2010.
How transformational leadership predicts employees’ affective commitment and performance
Authors: Ribeiro Neuza , Yücel İlhami , Gomes Daniel 
Published: October 2018

Purpose
The purpose of this paper is to examine the impact of transformational leadership (TL) on employees’ individual performance (IP) through the mediating role of affective commitment (AC). More specifically, it aims to understand how TL relates to employees’ AC, TL relates to employees’ IP, employees’ AC relates to IP and employees’ AC mediates the relationship between TL and employees’ IP.

Design/methodology/approach
A total of 476 Turkish healthcare professionals participated in this study. The mediation effect of AC in the relationship between TL and employees’ IP was tested by structural equation modeling.

Findings
The results indicate that AC mediates the relationship between TL and employees’ IP. In others words, transformational leaders promote employees’ AC which, in turn, increases their IP.

Practical implications
This study suggests that organizations should select, develop and invest in leaders who adopt a TL style because they build a climate of admiration, loyalty, respect, participation and involvement for employees which will in turn enhance their commitment and performance.

Originality/value
This study responds to calls for research studies to explore the mediating mechanism in the TL process (Judge et al., 2006), as the mediation effects explain the conditions in which TL is related to the favorable outcomes.

Measurement invariance of employee engagement across race groups
Authors: Gallant Wesley Herscelle , Martins Nico 
Published: October 2018

PurposeThe testing of measurement invariance is important in cross-cultural research to establish whether the psychometric properties of an instrument remain valid and reliable across different sample groups as these assumptions are rarely tested statistically. The purpose of this paper is to determine the factorial invariance of the employee engagement questionnaire across the various race groups by means of structural equation modelling.Design/methodology/approachCross-sectional and descriptive research designs were followed in this study in the form of non-probability, convenience sampling to attract a sample of 1,175 employees in financial institutions. The employee engagement instrument (EEI) was electronically administered to 285,000 people who form part of a research database.FindingsThe results confirmed the reliability and validity of the instrument as determined by the exploratory and confirmatory factor analysis. Lastly, the results indicated that invariance can be assumed across race groups for financial institutions.Practical implicationsIt is important for organisations to take cognisance of how specific socio-demographic variables influence the measurement of employee engagement, in this case race. The conclusion reached was that the EEI can be used with confidence in the financial sector for future employee engagement assessments.Originality/valueThese findings add to the current body of literature that exists on employee engagement and race in the South African work context and addresses one of the complexities assessment practitioners might have to comply with regarding questionnaire validity across race groups.
Measuring resource efficiency and resource effectiveness in manufacturing
Authors: Gharfalkar Mangesh , Ali Zulfiqur , Hillier Graham 
Published: October 2018

PurposeThe purpose of this paper is twofold: first, to identify and analyse existing resource efficiency (RE) and resource effectiveness measures and indicators (REMIs); and second, to identify gaps and develop a new indicator of “operational resource effectiveness” (OREft) suitable for manufacturing units.Design/methodology/approachResearch methodology consists of three stages: gap identification, development and testing. Through review of academic literature, 40 REMIs are identified and analysed. A survey of manufacturers is carried out to validate the hypothesis and seek inputs on the development of the new indicator. The proposed indicator is tested by comparing OREftindex of two manufacturing units with each other, with resource intensity per unit (RIPU), waste intensity per unit (WIPU) and with four other REMIs.FindingsAnalysis of 40 REMIs clearly points towards the absence of a hypothesised REMI. In total, 78 per cent of manufacturers surveyed in north England substantiate the hypothesis. Inverse correlation established between the proposed OREftindicator, RIPU, WIPU and other comparisons is likely to validate the output generated by the proposed indicator.Research limitations/implicationsTesting of this indicator is limited to two dissimilar manufacturing units that shared data.Practical implicationsThe proposed indicator is useful for comparing the operational resource effectiveness of individual factories over a period as well as with other factories. RIPU and WIPU captured in this indicator also represent operational RE that can be used to initiate improvement action.Originality/valueInclusion of both, the resource consumption and the waste generation along with discount/multiplying factors that capture the circularity aspects is likely to be the distinguishing feature of this indicator.
The impact of corporate finance decisions on market value in emerging markets
Authors: Aras Guler , Mutlu Yildirim Filiz 
Published: October 2018

Purpose
The purpose of this paper is to analyze the conformity of the impact of corporate finance decisions on market value with the basic theoretical approaches in the two emerging economies, which show great similarities in terms of the economic structures, and to examine the results obtained by determining how these decisions affect market value comparatively.

Design/methodology/approach
In this study, the effect of corporate finance decisions on market value is tested empirically with panel data analysis method by using data of 274 real sector firms traded in BIST and 249 firms in BOVESPA industry index, between 2010 and 2014.

Findings
The analysis results show that the increase in the borrowing level of firms operating in both countries reduces the market value; the increase in the level of profitability in the firms has a positive effect on the market value. In addition, it is possible to say that the effect is different in terms of investment decisions for Turkish and Brazilian firms.

Research limitations/implications
The limitations of the study are that the non-financial sectors between 2010 and 2014 in Turkey and Brazil including the company data, and the companies with missing years are removed from the data set. The findings show that more effective and balanced management of the variables by the financial manager affects these rates and have an impact on increasing the market value.

Originality/value
In this study, a fundamental subject in finance is addressed by analytical methodology and comparative tests for countries are conducted.
Critical success factors for Kaizen implementation in the Nigerian construction industry
Authors: Omotayo Temitope Seun , Kulatunga Udayangani , Bjeirmi Bassam 
Published: October 2018

Purpose
Kaizen in construction is a new paradigm stemming out of lean production systems. Construction companies in developing economies, such as Nigeria, have a task to innovate to liquidate in certain cases. With the aid of kaizen, which encompasses the benefit of stakeholder relationship improvement and management, profitability enhancement and delivery of projects to satisfied clients, construction companies can realise expected growth. An exploration of the critical success factors (CSF) and associated drivers within the limits of the scope is essential. The paper aims to discuss these issues.

Design/methodology/approach
Exploratory factor analysis statistical tests categorised the CSF identified in the literature review section. A detailed sampling approach extracted 135 questionnaires under the five-point Likert scale format from a larger population in Nigeria. An exploration of important drivers and iteration of eigenvalues combined with asymptotic significance of the drivers provided the CSF and significant drivers.

Findings
Construction management function, operational efficiency, construction business ethics and construction cost management were the CSF established from the exploratory factor analysis tests. It was confirmed that kaizen can be adopted in Nigerian construction companies with reflections on the principal drivers for the CSF.

Research limitations/implications
The exploration of the CSF and drivers associated with kaizen implementation can be applied to other developing countries with considerations of implementation in terms of cost and time.

Originality/value
The identification of CSF provides ample opportunity for consideration of kaizen in construction companies. The findings of this study are a basis for investigations into cost and time implications of kaizen adoption in construction companies.
