Progress in thermal transport modeling of carbonate-based reacting systems
Authors: Yue Lindsey , Reich Leanne , Simon Terrence , Bader Roman , Lipiński Wojciech 
Published: April 2017

Purpose
Carbonate-based heterogeneous reacting systems are investigated for the applications of thermochemical carbon dioxide capture and energy storage. This paper aims to review recent progress in numerical modeling of thermal transport phenomena in such systems.

Design/methodology/approach
Calcium oxide looping is selected as the model carbonate-based reacting system. Numerical models coupling heat and mass transfer to chemical kinetics are reviewed for solar-driven calcium oxide looping on the sorbent particle, particle bed, and reactor levels.

Findings
At the sorbent particle level, a transient numerical model of heat and mass transfer coupled to chemical kinetics has been developed for a single particle undergoing cyclic calcination and carbonation driven by time-periodic boundary conditions. Modeling results show cycle times impact the maximum sorbent utilization and solar-to-chemical energy efficiency. At the reactor level, a model of heat and mass transfer coupled to chemical kinetics of calcination of a packed-bed reactor concept has been developed to estimate the reactor’s performance. The model was used to finalize reactor geometry by evaluating pressure drops, temperature distributions, and heat transfer in the reactor.

Originality/value
Successful solar thermochemical reactor designs maximize solar-to-chemical energy conversion by matching chemical kinetics to reactor heat and mass transfer processes. Modeling furthers the understanding of thermal transport phenomena and chemical kinetics interactions and guides the design of solar chemical reactors.

Authors: Prather Ray O. , Kassab Alain , Ni Marcus William , Divo Eduardo , Argueta-Morales Ricardo , DeCampli William M. 
Published: April 2017

Purpose
Predictive models implemented in medical procedures can potentially bring great benefit to patients and represent a step forward in targeted treatments based on a patient’s physiological condition. It is the purpose of this paper to outline such a model.

Design/methodology/approach
A multi-scale 0D-3D model based on patient specific geometry combines a 0-dimensional lumped parameter model (LPM) with a 3D computational fluid dynamics (CFD) analysis coupled in time, to obtain physiologically viable flow parameters.

Findings
A comparison of physiological data gathered from literature with flow-field measurements in this model shows the viability of this method in relation to potential predictions of pathological flows repercussions and candidate treatments.

Research limitations/implications
A limitation of the model is the absence of compliance in the walls in the CFD fluid domain; however, compliance of the peripheral vasculature is accounted for by the LPM. Currently, an attempt is in progress to extend this multi-scale model to account for the fluid-structure interaction of the ventricular assist device vasculature and hemodynamics.

Originality/value
This work reports on a predictive pulsatile flow model that can be used to investigate surgical alternatives to reduce strokes in LVADs.

Authors: Gerges Michael , Mayouf Mohammad , Rumley Peter , Moore David 
Published: April 2017

Purpose
The purpose of this paper is to investigate human behaviour under a situation of fire in high-rise residential buildings and identify the factors that motivate people to evacuate.

Design/methodology/approach
A literature review was conducted to identify different factors of human behaviour during a situation of fire and identify challenges during the evacuation. Through a mixed research method approach, the paper identifies human background, experience and knowledge with fire safety. The paper discusses the challenges occupants face during evacuation based on previous evacuation experience and what occupants were doing during the fire alarm.

Findings
The paper has identified the challenges and the factors that affect occupants’ decision during fire emergency in high-rise residential buildings. It is clear from the findings that occupants have limited knowledge and skills on how to deal with fire emergencies. Occupants tend to depend on other evacuation routes. Occupants tend to ignore the fire alarm and usually they investigate if it is true or false.

Originality/value
The paper provides the knowledge and findings of occupants during fire emergency to fire engineers, facility managers, owners, and other professionals to assist during the design phase, and modify designs based on this findings of this research.
Wearing comfort analysis from aspect of numerical garment pressure using 3D virtual-reality and data mining technology
Authors: Liu Kaixuan , Wang Jianping , Hong Yan 
Published: April 2017

Purpose
The purpose of this paper is to find out the main factors that influence wearing comfort and how they influence garment-wearing comfort.

Design/methodology/approach
Overall, 120 postures were extracted from the activities of daily life and work. Then, the numerical values of clothing pressure of these postures were measured using three-dimension virtual-reality technology. Finally, the data mining technology was applied to analyze the collected data.

Findings
The wearing comfort of pants is mainly influenced by four factors – waist-hip factor, knee-shank factor, crotch factor and thigh-calf factor – and their contributions account for 39.17, 16.4, 13.96 and 6.95 percent, respectively. Hip, waist, crotch and knee influence wearing comfort significantly, and the part below the knee and the part of back thigh have no obvious effect on wearing comfort. Furthermore, the wearing comfort is acceptable if the numerical clothing pressures are below 20 kPa at the parts of hip, waist and crotch and below 10 kPa at the parts of back thigh, knee and shank.

Originality/value
The paper demonstrates how different human body parts influence garment-wearing comfort. All of the results in this research facilitate pattern design of pants and quantitative evaluation of garment-wearing comfort.
Wellness tourism: stress alleviation or indulging healthful habits?
Authors: Hudson Simon , Thal Karen , Cárdenas David , Meng Fang 
Published: April 2017

Purpose
This study aims to examine the direct relationships between behavioral intention and factors driving the growth of the wellness tourism industry in the USA. Relationships were hypothesized based on alternative explanations for the rise in popularity of wellness tourism in research streams.

Design/methodology/approach
Two models were estimated and tested using the theory of planned behavior (TPB), each incorporating two constructs – Life stress and involvement in health – in addition to theoretically stipulated precursors to Behavioral Intention.

Findings
Both constructs were found to be significant predictors of behavioral intention. However, involvement proved a much stronger predictor than life stress. Implications for the management and marketing of this subsector are discussed in the paper.

Originality/value
This study extends the understanding of travelers’ behavioral intentions in the context of wellness tourism by using an extended TPB, with life stress and involvement in health and wellness considered. The study compares general travelers with current/potential wellness travelers (excluding those whose sole purpose was wellness) and the factors that influence their travel behavior.
Start-up competitions as learning environment to foster the entrepreneurial process
Authors: Passaro Renato , Quinto Ivana , Thomas Antonio 
Published: April 2017

Purpose
The purpose of this paper is threefold: first, to shed light on the increasing start-up competitions (SUCs) phenomenon; second, to provide an interpretive framework to understand whether the SUCs have the potential to be effective entrepreneurial learning environment; third, to analyse the different roles of public and private actors in organizing SUCs.

Design/methodology/approach
The paper presents a cross-section analysis of the Italian SUCs population. In total, 77 competitions are analysed on the basis of different criteria which should properly mirror their distinguishing structural features, helping understand the potential of SUCs as learning environments.

Findings
The recent increase in the number of SUCs has been mainly fuelled by private actors. Moreover, Italian SUCs show some features that make them rich learning environments. Private and public actors play different roles, as confirmed by statistical tests performed. Privately organized SUCs follow mainly a market-oriented approach, while publicly organized ones are more education oriented.

Research limitations/implications
The findings cannot be easily generalized mainly due to the peculiarities of the Italian context.

Practical implications
Soft forms of regulation should be defined to strengthen those features which could potentially support the entrepreneurial learning processes. In this view, SUCs should be part of a start-up friendly ecosystem where actors (startuppers, incubators, venture capitalists) are effectively coordinated with each other.

Originality/value
Despite the remarkable diffusion of SUCs, there are significant gaps in literature about this phenomenon. Given the lack of a systematic and comprehensive analysis of SUCs as effective entrepreneurial learning environments, the paper represents an important starting point.
Prior exposure to entrepreneurship and entrepreneurial beliefs
Authors: McCann Brian T. 
Published: April 2017

Purpose
To contribute to the knowledge of factors that shape entrepreneurial beliefs, the purpose of this paper is to theorize and empirically test how individuals’ general attitudes toward entrepreneurship based on exposure to others’ prior entrepreneurial activities are related to beliefs surrounding current entrepreneurial opportunities. Positive attitudes based on prior exposure can lead to bias in the beliefs about current opportunities being evaluated, suggesting that positive affect can be a negative influence in the entrepreneurial process.

Design/methodology/approach
The sample is the Panel Study of Entrepreneurial Dynamics I, a nationally representative, longitudinal data set of US adults in the process of starting businesses. Regression analyses demonstrate how general attitudes are associated with beliefs about level of future sales, probability of venture survival, and levels of financial, competitive, and operational uncertainty.

Findings
Nascent entrepreneurs with more positive general attitudes toward entrepreneurship form more optimistic estimates of the financial performance and survival likelihood of their future ventures. They also estimate lower levels of environmental uncertainty.

Originality/value
This research extends understanding of the impact of prior exposure to entrepreneurship in the entrepreneurial process. It also contributes to increasing understanding of the determinants of entrepreneurial beliefs and extends prior work that has considered cognitive determinants (knowledge and motivation) to consider emotional determinants (affect-infused attitudes), consistent with the heightened recent interest in the role of emotion in entrepreneurship. This research provides a different perspective on the role of affect in the entrepreneurial process. While prior work addressing affect in entrepreneurship has explored the positive aspects of affect, the present study suggests that affect may not have a uniformly positive influence.
Teacher effectiveness through self-efficacy, collaboration and principal leadership
Authors: Sehgal Prachee , Nambudiri Ranjeet , Mishra Sushanta Kumar 
Published: April 2017

PurposeTeacher effectiveness has been a matter of concern not only for the parents and students but also for the policy makers, researchers, and educationists. Drawing from the “self-efficacy” theory (Bandura, 1977), the purpose of this paper is to explore the relationship between teacher self-efficacy and teacher effectiveness. In addition, it explores the role of collaboration among teachers and principal leadership in explaining the above relationship.Design/methodology/approachData were collected from 575 secondary school teachers and 6,020 students representing grade 6-12th from 25 privately owned schools in India. Teacher self-efficacy, collaboration and principal leadership were reported by the teachers whereas effectiveness of each teacher was captured from around ten students each who were taught by the corresponding teacher. Data were analyzed using SEM-PLS.FindingsResults confirmed a positive association between teacher self-efficacy and the three dimensions of teacher effectiveness, namely, teacher’s delivery of course information, teacher’s role in facilitating teacher-student interactions, and teacher’s role in regulating students’ learning. Results also confirmed that both collaboration and principal leadership are positively related to teacher self-efficacy.Originality/valueThe results of the study indicate that schools need to focus on enhancing self-efficacy of their teachers and give importance to teacher collaboration and principal leadership in order to improve their effectiveness in terms of delivery of instruction, teacher-student interactions, and regulating student learning.
Reliability analysis of multi-state system with application of multiple-valued logic
Authors: Zaitseva Elena , Levashenko Vitaly 
Published: April 2017

Purpose
The purpose of this paper is to develop a new mathematical method for the reliability analysis and evaluation of multi-state system (MSS) reliability that agrees with specifics of such system. It is possible based on the application of multiple-valued logic (MVL) that is a natural extension of Boolean algebra used in reliability analysis.

Design/methodology/approach
Similar to Boolean algebra, MVL is used for the constriction of the structure function of the investigated system. The interpretation of the structure function of the MSS in terms of MVL allows using mathematical methods and approaches of this logic for the analysis of the structure function.

Findings
The logical differential calculus is one of mathematical approaches in MVL. The authors develop new method for MSS reliability analysis based on logical differential calculus, in particular direct partial logical derivatives, for the investigation of critical system states (CSSs). The proposed method allows providing the qualitative and quantitative analyses of MSS: the CSS can be defined for all possible changes of any system component or group of components, and probabilities of this state can also be calculated.

Originality/value
The proposed method permits representing the MSS in the form of a structure function that is interpreted as MVL function and provides the system analyses without special transformation into Boolean interpretation and with acceptable computational complexity.
Availability and cost analysis of an engineering system involving subsystems in series configuration
Authors: Kumar Anuj , Pant Sangeeta , Singh S.B. 
Published: April 2017

Purpose
The purpose of this paper is to evaluate various reliability measures like availability, reliability, mean time to failure and profit function.

Design/methodology/approach
The authors present a novel method for availability analysis of an engineering system incorporating waiting time to repair. The considered system consists of two subsystems, namely, A and B connected in series. The subsystem B has two identical units in standby arrangement. Each unit of the subsystem has two modes, i.e. normal efficiency or failed. The two standby units of the subsystem B are connected by an imperfect switching. The system is analyzed by supplementary variable technique, Laplace transformation and Gumbel-Hougaard family of copula.

Findings
Numerical examples with a way to highlight the important results have been appended at last. Numerical calculation shows that availability and reliability of the system is decreasing with respect to time when failure rates are fixed at different values. Finally, cost analysis of system reveals that the expected profit decreases with increase in service cost.

Originality/value
This paper presents a mathematical model in which an important aspect of switching has been taken into consideration, which is consistent with actual failures of switching by assuming two different types of failure between adjacent transition. It is evaluated with the help of the Gumbel-Hougaard family of copula.
Too new or too complex? Why consumers’ aesthetic sensitivity matters in apparel design evaluation
Authors: Seifert Christin , Chattaraman Veena 
Published: April 2017

Purpose
The purpose of this paper is to examine the individual and joint effects of collative design factors, complexity and novelty, on aesthetic response to apparel products; and whether the influence of these factors is moderated by consumers’ centrality of visual product aesthetics (CVPA).

Design/methodology/approach
A mixed factorial experimental design, using women’s tops with design complexity and novelty (high vs low) manipulated orthogonally, was conducted among 260 female participants to test the model and its corresponding hypotheses.

Findings
Consumers’ aesthetic response was more positive for high than low complexity and novelty apparel designs. Further, when viewed in combination, high complexity + low novelty and low complexity + high novelty apparel designs were favored over high complexity + high novelty and low complexity + low novelty apparel designs, respectively. High CVPA consumers were more distinguishing than low CVPA consumers with respect to novelty in apparel designs.

Practical implications
This study suggests that firms need to be aware that complexity and novelty are crucial for consumers when judging apparel designs.

Originality/value
This study fills an important knowledge gap in the aesthetics literature by drawing on the processing fluency theory and Wundt curve and considering the joint effect of novelty and complexity, both critical determinants of a product’s marketplace success.
Shariah-compliant investments and stock returns: evidence from the Indonesian stock market
Authors: Lusyana Devi , Sherif Mohamed 
Published: April 2017

PurposeThe purpose of this paper is to investigate the impact of the IndonesiaShariah-compliant Stock Index (ISSI) on the performance of included shares. In essence, the authors ask whether the establishment of the ISSI provides abnormal returns for the firms that are not included in the Jakarta Index.Design/methodology/approachThe authors use an event study methodology to estimate cumulative abnormal returns in the days surrounding the event to examine the relationship betweenShariah-compliant investments and stock returns. The estimation window of 90 trading days prior to the event (−30) to day 60 after (+60) is adopted. They also use a range of investment performance measures to provide new evidence on whether faith-based ethical investments generate superior performance compared to their unscreened benchmarks.FindingsUsing daily returns, the Indonesia ISSI and panel data model, the findings show that the inclusion of the ISSI has a positive impact on the financial performance of the included shares during the 41-day event window. The evidence also suggests that the ethical investment has a significant influence on the performance of stock market returns.Research limitations/implicationsThis study offers insights to policymakers, investors and fund managers interested in the indices’ performance. A key conclusion that could be derived by bodies that regulate Islamic products and services is that investors are not only concerned about what is profitable but also what makes their investments ethical.Originality/valueAlthough the global growth of the Islamic capital market products and services has been tremendous in recent years, very few studies focus on the Indonesian market and indeed, none of them devote sufficient attention toShariah-compliant investments and stock returns.

Authors: Hegner Sabrina M. , Fetscherin Marc , van Delzen Marianne 
Published: April 2017

Purpose
The purpose of this paper is to explore and discuss the concept of brand hate. The authors present a taxonomy of the main determinants and outcomes of brand hate and empirically assess our model.

Design/methodology/approach
A survey design using cross-sectional primary data from 224 German consumers was used. Hypotheses related to determinants and outcomes of brand hate were tested by means of structural equation modelling.

Findings
Findings show that brand hate is triggered by three determinants (negative past experience, symbolic incongruity, ideological incompatibility) and leads to three behavioral outcomes (brand avoidance, negative word-of mouth, brand retaliation).

Originality/value
This paper explores and outlines theoretically and empirically the determinants and outcomes of brand hate. It also provides a useful taxonomy of brand hate.
Grass-mud horse: Luhmannian systems theory and internet censorship in China
Authors: Clark Carlton , Zhang Lei 
Published: April 2017

Purpose
This paper aims to elucidate the systemic processes underlying the enhanced information-control measures taken by the Chinese Communist Party (CCP) under the leadership of President Xi Jinping. The tightening of state information control has stimulated increasingly sophisticated methods of disseminating information on the part of professional and citizen journalists. Drawing on social systems theory as articulated by Niklas Luhmann and others, the authors frame the CCP’s enhanced information-control efforts as a response to the increasing systemic complexity of Chinese journalism, which is part of a self-reproducing, self-regulating (autopoietic) global journalism system. The authors use both subtle and overt protests over Chinese censorship as evidence for the journalism system’s increasing complexity and autonomy. The authors observe that levels of complexity ratchet up as the CCP and Chinese journalism counter each other’s moves. Finally, the authors suggest that the increasing complexity of the CCP’s information-control apparatus may be unsustainable.

Design/methodology/approach
The authors ground their argument in Luhmannian social systems theory.

Findings
The CCP's effort to control journalism leads to increased internal complexity in the form of huge bureaucracies that themselves must be overseen in an almost endless proliferation of surveillance.

Research limitations/implications
This paper contributes to theoretical work in post-humanism.

Originality/value
To the authors’ knowledge, no studies have examined the tension between CCP censors and Chinese journalism from a Luhmannian systems theory perspective.
