Authors: Shmueli Galit , Sarstedt Marko , Hair Joseph F. , Cheah Jun-Hwa , Ting Hiram , Vaithilingam Santha , Ringle Christian M. 
Published: June 2019

PurposePartial least squares (PLS) has been introduced as a “causal-predictive” approach to structural equation modeling (SEM), designed to overcome the apparent dichotomy between explanation and prediction. However, while researchers using PLS-SEM routinely stress the predictive nature of their analyses, model evaluation assessment relies exclusively on metrics designed to assess the path model’s explanatory power. Recent research has proposed PLSpredict, a holdout sample-based procedure that generates case-level predictions on an item or a construct level. This paper offers guidelines for applying PLSpredict and explains the key choices researchers need to make using the procedure.Design/methodology/approachThe authors discuss the need for prediction-oriented model evaluations in PLS-SEM and conceptually explain and further advance the PLSpredict method. In addition, they illustrate the PLSpredict procedure’s use with a tourism marketing model and provide recommendations on how the results should be interpreted. While the focus of the paper is on the PLSpredict procedure, the overarching aim is to encourage the routine prediction-oriented assessment in PLS-SEM analyses.FindingsThe paper advances PLSpredict and offers guidance on how to use this prediction-oriented model evaluation approach. Researchers should routinely consider the assessment of the predictive power of their PLS path models. PLSpredict is a useful and straightforward approach to evaluate the out-of-sample predictive capabilities of PLS path models that researchers can apply in their studies.Research limitations/implicationsFuture research should seek to extend PLSpredict’s capabilities, for example, by developing more benchmarks for comparing PLS-SEM results and empirically contrasting the earliest antecedent and the direct antecedent approaches to predictive power assessment.Practical implicationsThis paper offers clear guidelines for using PLSpredict, which researchers and practitioners should routinely apply as part of their PLS-SEM analyses.Originality/valueThis research substantiates the use of PLSpredict. It provides marketing researchers and practitioners with the knowledge they need to properly assess, report and interpret PLS-SEM results. Thereby, this research contributes to safeguarding the rigor of marketing studies using PLS-SEM.

Authors: Mousavi Seyed Mohammad , Akbari Omid Ali , Sheikhzadeh Ghanbarali , Marzban Ali , Toghraie Davood , Chamkha Ali J. 
Published: June 2019

Purpose
The purpose of this study is two phase modeling of Water/Cu nanofluid forced convection in different arrangements of elliptical tube banks in a two-dimensional space.

Design/methodology/approach
The arrangements of tube banks have been regarded as equal spacing triangle (ES), equilateral triangle (ET) and the rotated square (RS). The obtained results indicate that, among the investigated arrangements, the RS arrangement has the maximum value of heat transfer with cooling fluid. Also, the changes of Nusselt number and the local friction factor are under the influence of three main factors including volume fraction of slid nanoparticles, the changes of fluid velocity parameters on the curved surface of tube and flow separation after crossing from a specified angle of fluid rotation.

Findings
In Reynolds number of 250 and in all arrangements of the tube banks, the behavior of Nusselt number is almost the same and the separation of flow happens in almost 155-165 degrees from fluid rotation on surface. In RS arrangement, due to the strength of vortexes after fluid separation, better mixture is created and because of this reason, after the separation zone, the level of local Nusselt number graph enhances significantly.

Originality/value
In this research, the laminar and two-phase flow of Water/Cu nanofluid in tube banks with elliptical cross section has been numerically investigated in a two-dimensional space with different longitudinal arrangements. In this study, the effects of using nanofluid, different arrangements of tube banks and the elliptical cross section on heat transfer and cooling fluid flow among the tube banks of heat exchanger have been numerically simulated by using finite volume method.
Investigation of viscous fluid flow and dynamic stability of CNTs subjected to axial harmonic load coupled using Bolotin’s method
Authors: Hashemian Mohammad , Vaez Amir Homayoun , Toghraie Davood 
Published: June 2019

Purpose
The dynamic stability of nano-tubes is an important issue in engineering applications. Dynamic stability of anti-symmetric coupled-carbon nanotubes (C-CNTs)-systems in thermal environment is presented in this paper. In this system, the top and bottom CNTs are subjected to axial harmonic load and action of the viscous fluid, respectively.

Design/methodology/approach
The coupling and surrounding mediums of the CNTs are simulated by visco-Pasternak foundation containing the spring, shear and damper coefficients. Based on the Timoshenko beam theory and Hamilton’s principle, the coupled motion equations are derived considering size effects using Eringen’s nonlocal theory. Using the exact solution in conjunction with Bolotin’s method, the dynamic instability region (DIR) of the coupled structure is obtained. The effects of various parameters such as small scale parameter, Knudsen number, fluid velocity, static load factor, temperature change, surrounding medium and nanotubes aspect ratio are shown on the DIR of the coupled system.

Findings
Results indicate that considering parameters such as small scale effects, static load factor, Knudsen number and fluid velocity shifts the DIR of C-CNTs to a lower frequency zone.

Originality/value
To the best of our knowledge, analyses of anti-symmetric coupled CNTs have not received enough attentions so far. In order to optimize the nanostructures designing, the main purpose of the present paper is to investigate nonlocal dynamic stability of CNTs subjected to axial harmonic load coupled with CNTs conveying fluid.
Temperature distribution analysis in a fully wet moving radial porous fin by finite element method
Authors: Gireesha B.J. , Sowmya G. , Macha Madhu 
Published: June 2019

Purpose
This paper aims to study the temperature performance with natural convection and radiation effect on a porous fin in fully wet condition.

Design/methodology/approach
The finite element method (FEM) is applied to generate numerical solution of the obtained non-dimensional ordinary differential equation containing highly nonlinear terms. The parameters which impact on the heat transfer of fin have been scrutinized by means of plotted graphs.

Findings
The porous fin is taken for the analysis in radial profile moving with constant velocity. Here, the thermal conductivity is considered to be temperature dependent. The Darcy’s model has been implemented to study the heat transfer analysis.

Originality/value
The paper is genuine in its type, and there are hardly any works on fins as per the authors’ knowledge.
Investigation of the institutional and decision-usefulness factors in the implementation of accrual accounting reforms in the public sector of Tanzania
Authors: Mbelwa Latifa Hamisi , Adhikari Pawan , Shahadat Khandakar 
Published: June 2019

PurposeThe purpose of this paper is to investigate the factors that have resulted in the effective implementation of accrual accounting reforms in the Central Government of Tanzania.Design/methodology/approachThe paper relies on the ideas of institutional theory and some aspects of decision-usefulness so as to delineate the external pressures enforcing the Government of Tanzania to embrace accrual accounting and the factors complicating its implementation at organisational level (within government entities). The authors draw on quantitative techniques and the explanatory and cross-sectional survey research strategies and methods for data analysis.FindingsOur findings suggest that the coercive pressures from donors and auditors along with the normative pressures surfaced by the training of employees generate a significant impact on designing the effective administrative model of accrual accounting. In a lesser extent, pressures from the National Board of Accountants and Auditors and cultural factors are positively correlated to the implementation of accrual accounting in the Tanzanian context. Of the factors the authors examined, the management changes are proved to be least effective. Unawareness of the key stakeholders has caused weak political and regulatory commitments. Accrual accounting implementation is further exacerbated by inadequate technical and personnel competence. Ultimately, the implementation of the accrual accounting has increased significant managerial accountability though a major segment of such behaviour is unexplained by the factors the authors employed in the study.Practical implicationsThe effective implementation of accrual accounting relies on improvements in cultural and human-related issues. What is important to understand is that accrual accounting is more of a management reform incorporating changes in broader aspects of institutional and accountability mechanisms, rather than just an adoption of particular accounting technologies. Without such broader changes, accrual accounting reforms can be detrimental providing the technocrats and government officials with a space for manipulating financial information, Tanzania serving as an example.Originality/valueThe study highlights the case of an emerging economy in which accrual accounting is actually in effect and has impacted on managerial accountability, but is struggling to engender intended results and outcomes at organisational level.
Muslims’ willingness to pay for certified halal food: an extension of the theory of planned behaviour
Authors: Iranmanesh Mohammad , Mirzaei Maryam , Parvin Hosseini Seyed Mehrshad , Zailani Suhaiza 
Published: June 2019

Purpose
The purpose of this paper is to extent the theory of planned behaviour (TPB), when extended by self-identity and religious commitment (RC), and is able to predict Muslim consumers’ willingness to pay (WP) for certified halal food.

Design/methodology/approach
A survey of 277 Muslim consumers in Malaysia was conducted and the cross-sectional data were analysed using the partial least squares technique.

Findings
Attitude (ATT) and religious self-identity (RSI) were found to have a positive impact on WP for certified halal food. Additionally, RC has a positive effect on ATT and RSI and has a positive moderating effect on the relationship between perceived behavioural control and WP.

Practical implications
The findings can benefit halal food companies by offering an insight into the willingness of Muslim consumers to pay for certified halal food.

Originality/value
The findings contribute to the research on halal foods by illustrating the factors that determine Muslim consumers’ WP for certified halal food. This study also extends the understanding of the TPB to the halal food context.
Linear analysis of a two-dimensional multistorey reinforced concrete frame under high temperature at different column locations
Authors: N. Parthasarathi , K.S. Satyanarayanan , V. Thamilarau , M. Prakash , Punnapu Adithya 
Published: June 2019

Purpose
The purpose of this study is to investigate the influence of progressive collapse under high temperature for a reinforced concrete (RC) frame. An analytical programme was analysed for a two-bay five-storey RC frame exposed to high temperature at different column locations.

Design/methodology/approach
The effects of high temperature protections and locations (i.e. corner, middle and intermediate) on collapse conditions and load distributions were studied for the steady-state linear analysis using finite element software.

Findings
The results show that the frame will not collapse suddenly at temperatures up to 400°C. This is attributed to an increase in the deflections of the column, which increases the lateral displacement of adjacent heated columns and governs their buckling. This indicates that the temperature rating in the column against collapse can occur at a range of 500°C-600°C compared to that of individual members. The collapse pattern of RC frames designed as ordinary moment resisting frames, and under ordinary load, combinations is based on GSA guidelines. The results for displacement, stress and axial force were collected and discussed.

Originality/value
The two-bay five-storey frame has been created in finite element software, and linear analysis is used to perform this study with a different temperature.
Innovation policy-making in the upstream oil and gas industry as a large technical system under economic transition
Authors: Ghazinoory S. Sepehr , Tatina Shiva , Goodarzi Mehdi 
Published: June 2019

Purpose
Innovation and technology development policy-making naturally encounters numerous uncertainties and complexities, especially in developing countries, for the sake of the prevailing prospect of decision makers focusing on hard evidences, and neglecting key and effective social ones; in this research, a context-based method by means of Q-methodology was designed to facilitate policy-making for complex systems by bridging between policy and practices (latent in viewpoints) through providing context-based evidences.

Design/methodology/approach
Due to the nature of knowledge-based systems, the performance of Innovation and Technology Development (ITD) systems is highly dependent on the standpoints of key players/stakeholders of the system. In consideration of Iran’s economy characteristics, Upstream Oil and Gas (UOG) Industry, which is one of the complex Large Technical Systems (LTS), was selected as a case study. Regarding the features of LTSs, the designed model was completed by adding hierarchical clustering method, as well as using the framework of innovation and technology learning transition model to analyze the results.

Findings
The results showed the capability of the model in providing credible evidences to inform policy-making processes.

Originality/value
This study is one of the first real experiences which used Q-method for providing evidence-based policy-making model in a complex Large Technical System, namely, Upstream Oil and Gas (UOG) Industry.
Improving energy efficiency in Vietnamese tube houses
Authors: Nguyen Phan Anh , Bokel Regina , Dobbelsteen Andy van den 
Published: June 2019

PurposeRefurbishing houses is considered a key measure to improve the energy efficiency of the built environment. However, little is known about the implementation and outcome of housing renovation for energy upgrades in the Vietnamese practice. The purpose of this paper is to investigate the energy performance of the current housing stock in Vietnam and the potential to reduce energy use in households.Design/methodology/approachThe paper is based on a survey with 153 respondents in three major climatic regions of Vietnam. The survey focusses on building characteristics, environmental performance, energy performance and refurbishment activities. Data collected from the survey were statistically analysed to give insight into the current performance of the housing stock and its energy saving potential.FindingsThis paper concludes that building design and construction, particularly the building envelope, have a significant influence on the occupants’ comfort. However, the energy consumption in houses is not statistically associated with building design and indoor environment. It is suggested that financial status and occupants’ behaviour currently have a strong influence on the household energy use. The survey also showed that refurbishment improves the housing performance, especially if improving the indoor environment was one of the drivers.Originality/valueThere are very few studies on energy use in households in Vietnam, especially with regards to actual energy consumption. This paper brings insights into the actual energy consumption and reveals the “performance gap” in Vietnamese housing stock.
Eco‐evolutionary perspectives of the dynamic relationships linking senescence and cancer
Authors: Lemaître Jean‐François , Pavard Samuel , Giraudeau Mathieu , Vincze Orsolya , Jennings Geordie , Hamede Rodrigo , Ujvari Beata , Thomas Frédéric 
Published: June 2019

Abstract

Evidence for actuarial senescence (i.e. the decrease in survival with increasing age) is now widespread across the tree of life. However, demographic senescence patterns are highly variable both between and within species. To understand these variations, there is an urgent need to go beyond aggregated mortality rates and to investigate how age‐specific causes of mortality in animals interact with age‐specific physiological performance. We address this question in the context of cancers.

Cancer is a leading cause of death in human populations and has recently been shown to be more prevalent across species than previously thought. Since anthropogenic perturbations drastically increase cancer rates in wild populations of animals, deciphering the complex interactions between senescence and cancer now constitutes a key challenge in evolutionary ecology.

Based on classical evolutionary theories of ageing, we first demonstrate that the occurrence of cancers might constitute an underestimated piece of the life‐history jigsaw. We propose that the selection for an increased allocation of resources towards growth and reproduction during early life might potentially favour cancer development, a life‐history pathway that might be functionally mediated by the process of immunosenescence. While we discuss the relevance of other proximate mechanisms suggesting that cancer arises as a direct consequence of senescence, we also argue that cancer itself can promote senescence by notably increasing the amount of resources required for somatic maintenance.

Contrary to theoretical predictions, recent empirical evidence suggests that senescence is an asynchronous process among physiological functions. At the same time, the timing of occurrence varies widely between the different types of cancers. We suggest that similar evolutionary forces might shape the synchronicity of senescence and cancer patterns, which emphasize the tight and complex relationships linking these processes.

We propose a conceptual background to lay down the foundations and the directions of future research projects aiming to disentangle the dynamic relationship between the evolution of cancer and senescence. We argue that studies embracing these research directions will markedly improve our understanding of both cancer prevalence and timing at the individual, population and species level.

Senescence in wild insects: Key questions and challenges
Authors: Zajitschek Felix , Zajitschek Susanne , Bonduriansky Russell 
Published: June 2019

Abstract

Insects are key laboratory models for research on the fitness effects, genetics and plasticity of senescence. It was long believed that insects almost never survive long enough to senesce in the wild, but it is now clear that senescence occurs and can exact substantial fitness costs in natural insect populations. Yet, given the practical challenges of obtaining longitudinal field data on small, motile animals, we still know remarkably little about the evolution, expression and fitness consequences of senescence in wild insects.

We argue that the study of senescence in wild insects is important because many insights and hypotheses based on laboratory experiments must be tested in natural populations.

Examples of research areas where conclusions from laboratory studies could be misleading include the roles of candidate senescence genes, the effects of nutrition and dietary restriction on life span and senescence patterns, and the roles of viability selection and sexual selection in shaping senescence through trade‐offs and antagonistic pleiotropy.

Several emerging model species (such as antler flies, crickets, damselflies, dragonflies and butterflies) offer opportunities for field research on senescence using a range of observational and experimental techniques, as well as new genomic approaches.

Insects provide valuable and increasingly tractable models for research on senescence in natural populations. We believe that such work will shed light on many important questions in ecology and evolutionary biology.
