The porous media theory applied to radiofrequency catheter ablation
Authors: Iasiello Marcello , Andreozzi Assunta , Bianco Nicola , Vafai Kambiz 
Published: September 2019

Purpose
Recently, the porous media theory has been successively proposed for many bioengineering applications. The purpose of this paper is to analyze if the porous media theory can be applied to model radiofrequency (RF) cardiac ablation.

Design/methodology/approach
Blood flow, catheter and tissue are modeled. The latter is further divided into a fluid and a solid phase, and porous media equations are used to model them. The heat source term is modeled using the Laplace equation, and the finite element method is used to solve the governing equations under the appropriate boundary conditions and closure coefficients.

Findings
After validation with available literature data, results are shown for different velocities and applied voltages to understand how these parameters affect temperature fields (and necrotic regions).

Research limitations/implications
The model might require further validation with experiments under different conditions after comparisons with available literature. However, this might not be possible due to the experimental complexity.

Practical implications
The improvement in predictions from the model might help the final user, i.e. the surgeon, who uses cardiac ablation to treat arrhythmia.

Originality/value
This is the first time that the porous media theory is applied to RF cardiac ablation. The robustness of the model, in which many variables are taken into account, makes it suitable to better predict temperature fields, and damaged regions, during RF cardiac ablation treatments.

Authors: Djebbar Khadidja El-Bahdja , Salem Souria , Mokhtari Abderrahmane 
Published: September 2019

Purpose
The purpose of this paper is to analyze energy performance of the multi-storey buildings built in the city of Tlemcen between 1872 and 2016.

Design/methodology/approach
A diagnosis based on a bottom-up methodology, using statistical techniques and engineering, has been developed and applied. To do this, demand condition analysis was conducted using a data collection survey on a sample of 100 case studies. Physical characteristics of the buildings have been determined through the archetype by period. This serves to define the strengths and weaknesses of buildings as energy consumers.

Findings
The obtained results showed that dwellings built between 1872 and 1920 offer better energy performance with a consumption index close to 130kWh/m2/year and this compared to the five periods considered. For dwellings built between 1974 and 1989, energy consumption is higher with an index approaching 300kWh/m2/year, thus qualifying the buildings of this period as energy intensive.

Originality/value
A database is established to collect physical information on the existing housing stock and thus allow their classification vis-à-vis of the energy label. This study is part of a research project aimed at evaluating and determining optimal measures for energy rehabilitation of multi-family buildings in Tlemcen. Thermal rehabilitation solutions are proposed using thermal simulations, in the following studies, to improve thermal performance of existing buildings. This study constitutes the first step of a roadmap applicable to other cities constituting climatic zones in Algeria. This helps to enrich the Algerian thermal regulation in thermal rehabilitation of existing residential buildings and conception of new ones, in urban areas with a similar climate.
Construction of China’s low-carbon competitiveness evaluation system
Authors: Wang Yongjing , Lan Qingxin , Jiang Feng , Chen Chaofan 
Published: September 2019

Purpose
As the contradiction between economic development, resource and environment has become increasingly prominent, low-carbon competitiveness has received worldwide focus. This study aims to examine low-carbon competitiveness in 31 provinces (cities and regions) of China.

Design/methodology/approach
An evaluation index system for low-carbon competitiveness in China has been constructed, which is composed of 25 economic, social, environmental and policy indicators. To study the state of low-carbon competitiveness and resistance to China’ development of low-carbon competitiveness, this study uses a combination of the catastrophe progression model, the spatial autocorrelation model and the barrier method.

Findings
China’ low-carbon competitiveness gradually decreases from coastal to inland areas: the Tibet and Ningxia Hui autonomous regions are the least competitive regions, while the Shandong and Jiangsu provinces are the most competitive areas. The spatial correlation of the 31 provinces’ low-carbon competitiveness is very low and lacks regional cooperation. This study finds that the proportion of a region’ wetland area, the proportion of tertiary industries represented in its GDP and afforestation areas are the main factors in the development of low-carbon competitiveness. China should become the leader of carbon competitiveness by playing the leading role in the Eastern Region, optimizing the industrial structure, improving government supervision and strengthening environmental protection.

Originality/value
The paper provides a quantitative reference for evaluating China’ low-carbon competitiveness, which is beneficial for environmental policymaking. In addition, the evaluation and analysis methods offer relevant implications for developing countries.

Authors: Moro Sérgio , Rita Paulo , Esmerado Joaquim , Oliveira Cristina 
Published: September 2019

Purpose
Airbnb Experiences is a new type of service launched by Airbnb in November 2016, where users can offer travellers a wide range of activities. This study devotes attention to analysing customer feedback expressed in online reviews published in Airbnb to evaluate those experiences.

Design/methodology/approach
A total of 1,110 reviews were collected from 12 categories, including 111 experiences, resulting in 10 reviews per experience. First, the sentiment score was computed based on the text of the reviews. Second, 17 quantitative features encompassing user, Airbnb experience and review information were used to model the score through a support vector machine. Third, a sensitivity analysis was performed to extract knowledge on the most relevant features influencing the sentiment score.

Findings
Tourists writing online reviews are not only influenced by their tourist experience but also by their own online experience with the booking and online review platform. The number of reviews made by the user accounted for more than 20 per cent of relevance, while users with more reviews tended to grant more positive reviews.

Originality/value
Current literature is enhanced with a conceptual model grounded on existing studies that assess tourist satisfaction with tour services. Both services online visibility and user characteristics have shown significant importance to tourist satisfaction, adding to the existing body of knowledge.
Evolutionary game of knowledge sharing in master-apprentice pattern of innovative organization
Authors: Wang Ruihua 
Published: September 2019

Purpose
Knowledge sharing in a master-apprentice pattern is the process of transferring tacit knowledge from masters to apprentices. In addition, 90 per cent of knowledge required for organizational innovation is tacit knowledge in the master-apprentice pattern. The purpose of this paper is to analyze the evolution of knowledge sharing in master-apprentice pattern and explore the consequences of how to improve the knowledge sharing in the master-apprentice pattern.

Design/methodology/approach
This paper uses asymmetric evolutionary game theory to study the evolutionary track of knowledge sharing in master-apprentice pattern of innovative organizations by analyzing the utility of masters and apprentices during the process of knowledge sharing in master-apprentice pattern of the innovative organization.

Findings
The results reveal that when the masters obtained utility from sharing knowledge is greater than that from hoarding knowledge, and the apprentices obtained utility from studying hard is greater than the costs, the innovative organization can get the largest utility from the knowledge sharing in the mater-apprentice pattern.

Research limitations/implications
The limitation of the research is that this paper mainly studies knowledge sharing among individuals and does not research knowledge sharing between individuals and organizations.

Practical implications
This research has extended the understanding of knowledge sharing in master-apprentice and its evolution path. Also, the obtained findings are conducive to promoting knowledge sharing in master-apprentice and improving human resource management in innovative organizations.

Originality/value
This paper attempts to construct the evolution path of knowledge sharing in master-apprentice pattern, which is a useful exploration of the dynamics of knowledge sharing in master-apprentice pattern and makes up for the shortcomings of the existing research.
Modeling of Islamic consumer behavior and background music regarding ambiguity in the Islamic texts
Authors: Akhavan Kharazian Maryam , Azadfar Vahed 
Published: September 2019

Purpose
This study aims to develop a model to analyze the effect of background music on Islamic consumer purchase behavior regarding to ambiguity in the Islamic texts.

Design/methodology/approach
In this experimental design, the population included chain store consumers in Tehran, among whom more than 17,000 consumers were selected during 42 days. ANOVA was used to analyze the collected data.

Findings
Based on the results, playing music in a store could significantly influence the total sales and average purchase value, while no positive role was observed on the number of purchases. Furthermore, dual impression form Islam viewpoints regarding music was observed in the present study as it failed to affect the number of sales in spite of influencing the amount of sales. Individuals affected by music buy more expensive goods, which may indicate that those who buy more luxury goods are less inclined to Islamic views or are inclined to those views which regards playing music as legitimate.

Research limitations/implications
Store managers and marketers in Islamic nation are recommended to play pop music in their store to improve total sales. Managers in islamic nation should play some music when they offer more luxury and less ordinary goods. Although the present study attempted to control potential intervening variables to increase validity, controlling intervening variables is a serious limitation for conducting a field study. Uncontrollable intervening variables established by other media are considered as another limitation in this study.

Originality/value
For the first time, this study sheds some light on how the types of background music influences on the Islamic consumers. The study shows the ambiguity in the islamic texts and the differences in the judgments of religious regarding playing music to muslim consumer.

Authors: Bibi Memoona , Sohail Muhammad , Naz Rahila 
Published: September 2019

PurposeThe purpose of this paper is to perform an analytical approximation for the flow of magnetohydrodynamic Carreau fluid with the association of nanoparticles over a rotating disk. The disk is moving with a constant uniform speed. Governing equations are obtained by using these assumptions in the form of partial differential equations with boundary conditions. These coupled, highly nonlinear equations are transformed into a coupled system of ordinary differential equations by engaging similarity transformation in the rotating frame of reference.Design/methodology/approachAn efficient and reliable scheme, namely optimal homotopy asymptotic method, is used to obtain the solutions of the arising physical problem, which is further analyzed graphically. After computing the solutions of the arising problem, plots of velocities, temperature and concentration are discussed briefly.FindingsIt has been observed that dimensionless velocity reduced due to magnetic effect between the boundary layer and escalating values of the magnetic parameter upsurges the temperature and concentration profiles. Contour plots and numerical results are given for local numbers like skin friction coefficient, Nusselt number and Sherwood number.Originality/valueThe work presented in this manuscript is neither published nor submitted anywhere for the consideration/publications. It is a novel work.
Application of double diffusion theories to Maxwell nanofluid under the appliance of thermal radiation and gyrotactic microorganism
Authors: Sohail Muhammad , Naz Rahila , Raza Rabeeah 
Published: September 2019

Purpose
The purpose of this paper is to address the entropy analysis of the 3D flow of Maxwell nanofluid containing gyrotactic microorganism in the presence of homogeneous–heterogeneous reactions with improved heat conduction and mass diffusion models over a stretched surface. Improved models are supported out by utilizing Cattaneo–Christov heat flux and generalized Fick’s law, respectively.

Design/methodology/approach
Governing equations which present the given flow phenomenon are modeled in the form of PDEs by applying boundary layer analysis and then suitable makeovers are engaged to transfigure prevailing partial differential equations into a set of ordinary differential equations. Transformed equations are handled via optimal homotopy analysis process in computational tool Mathematica and also a special case of already published work is substantiated and found to be in excellent settlement.

Findings
The bearing of innumerable convoluted physical parameters on velocity, temperature, concentration, reaction rate, the concentration of motile microorganism and entropy generation are presented and deliberated through graphs. Moreover, the convergence of the homotopic solution is presented in tabular form which confirms the reliability of the proposed scheme. It is perceived that mounting values of the magnetic parameter and Brinkman number boosts the irreversibility analysis and Bejan number diminishes for these parameters. Moreover, the growing values of Prandtl and Schmidt numbers reduce the temperature and concentration fields, respectively.

Practical implications
The work contained in this paper has applications in a different industry.

Originality/value
The work contained in this paper is original work and it is good for the researcher in the field of applied mathematics.
An empirical investigation of how information sharing affects cash flow performance through competitive capability
Authors: Lyngstadaas Hakim 
Published: September 2019

PurposeThis paper aims to examine how information sharing affects cash flow performance through the competitive capabilities of low cost or product quality.Design/methodology/approachIn total, 159 survey responses were collected from Norwegian manufacturing firms in 2018. Structural equation modelling (SEM) was used to analyse the data collected.FindingsThe low-cost competitive capability was found to positively mediate the effect of information sharing on cash flow performance. However, product quality competitive capability did not have a significant mediating effect between information sharing and cash flow performance. Rather, customer satisfaction fully mediated the relationship between product quality, capability and cash flow performance. The empirical results not only support how the competitive capabilities can be developed through information sharing but also illustrate that the competitive capabilities affect cash flow performance through different mediating routes.Originality/valueWhile information sharing and competitive capabilities have been studied previously with regard to financial performance, less emphasis has been placed on how customer satisfaction might explain the mediated relationship between product quality, competitive capability and financial performance. In addition, financial performance is measured by the proxy of cash flow. The use of cash flow as a performance measure leads to a more forward-looking financial performance measure. This is especially appropriate for non-listed firms.

Authors: Bueno-Guerrero Alberto 
Published: September 2019

Purpose
This paper aims to study the conditions for the hedging portfolio of any contingent claim on bonds to have no bank account part.

Design/methodology/approach
Hedging and Malliavin calculus techniques recently developed under a stochastic string framework are applied.

Findings
A necessary and sufficient condition for the hedging portfolio to have no bank account part is found. This condition is applied to a barrier option, and an example of a contingent claim whose hedging portfolio has a bank account part different from zero is provided.

Originality/value
To the best of the authors’ knowledge, this is the first time that this issue has been addressed in the literature.
What lessons have we learnt about the impact of maternal cigarette smoking from animal models?
Authors: Chan Yik L. , Oliver Brian G. , Chen Hui 
Published: September 2019

AbstractMaternal first‐ or second‐hand tobacco smoking during pregnancy is still common albeit that the detrimental effects to the unborn child are well known. Maternal tobacco cigarette smoking can affect multiple organ systems in the offspring, rendering them at increased risk of various conditions throughout life (eg. intrauterine underdevelopment, asthma, substance abuse, diabetes). However, this review will only focus on its impact on the brain and the related molecular changes in the offspring based on evidence from animal studies. Although epidemiological studies have identified the associations between maternal cigarette smoke exposure (SE) and brain disorders, animal models can help identify the underlying mechanisms and test interventions. Human studies have found that maternal SE is closely linked to small brain size and changes in brain structure and associated with a high risk of cognitive defects. Animal models suggest that this may be due to increased brain oxidative stress and inflammation during the neonatal period, leading to increased brain cell apoptosis in adulthood. There is a distinct gender bias of such impacts, where male offspring are more affected than females. Female offspring seem to have developed the adaptation by increasing endogenous antioxidant levels. Indeed, animal studies have shown that using antioxidant supplementation during pregnancy can improve neurological outcomes in male offspring, however, the efficacy in humans is yet to be confirmed. Furthermore, some animal studies suggested nicotine as the key player in intrauterine underdevelopment due to maternal SE, while human clinical trials using nicotine replacement therapy do not support this mechanism. This review will discuss the possible reasons.
Effects of interdental cleaning devices in preventing dental caries and periodontal diseases: a scoping review
Authors: Amarasena N , Gnanamanickam ES , Miller J 
Published: September 2019

AbstractTo identify and map existing evidence on the effectiveness of interdental cleaning devices in preventing dental caries and periodontal diseases, a scoping review was carried out by electronically searching PubMed, Scopus and Embase. Studies on interdental cleaning devices, written in English, and published from January 2008 up to April 2019 were included in the review. Of 1860 studies identified, six systematic reviews (SR) were included in the review. One SR each was on flossing, interdental brushes, wood sticks and oral irrigation. Of two SR on multitude of interdental cleaning devices, one assessed comparative efficacy while the other both the individual and comparative efficacy. All reviews had assessed the heterogeneity and the methodological quality of studies included, and performed data extraction and meta‐analysis where appropriate. Evidence ranged from weak to moderate with very low‐ to low‐certainty for the adjunctive benefit of these devices to control plaque and gingivitis. It warrants long‐term studies with sufficient power and those assessing the impact of interdental cleaning on interproximal caries to corroborate such evidence. Available evidence on the efficacy of interdental cleaning devices suggests that dental practitioners recommend patient‐specific interdental cleaning devices that enable patients to achieve a safe and high standard of interdental cleaning.
