An enthalpy-based model of dendritic growth in a convecting binary alloy melt
Authors: Bhattacharya Anirban , Dutta Pradip 
Published: September 2013

Purpose
– In the present work, a numerical method, based on the well established enthalpy technique, is developed to simulate the growth of binary alloy equiaxed dendrites in presence of melt convection. The paper aims to discuss these issues.

Design/methodology/approach
– The principle of volume-averaging is used to formulate the governing equations (mass, momentum, energy and species conservation) which are solved using a coupled explicit-implicit method. The velocity and pressure fields are obtained using a fully implicit finite volume approach whereas the energy and species conservation equations are solved explicitly to obtain the enthalpy and solute concentration fields. As a model problem, simulation of the growth of a single crystal in a two-dimensional cavity filled with an undercooled melt is performed.

Findings
– Comparison of the simulation results with available solutions obtained using level set method and the phase field method shows good agreement. The effects of melt flow on dendrite growth rate and solute distribution along the solid-liquid interface are studied. A faster growth rate of the upstream dendrite arm in case of binary alloys is observed, which can be attributed to the enhanced heat transfer due to convection as well as lower solute pile-up at the solid-liquid interface. Subsequently, the influence of thermal and solutal Peclet number and undercooling on the dendrite tip velocity is investigated.

Originality/value
– As the present enthalpy based microscopic solidification model with melt convection is based on a framework similar to popularly used enthalpy models at the macroscopic scale, it lays the foundation to develop effective multiscale solidification.
Simulation of multiphase flows in porous media with gravitational effects using dominant wave method
Authors: Moshiri M. , Manzari M.T. , Hannani S.K. , Rasouli A. 
Published: September 2013

Purpose
– In this paper, the flow of multiphase fluids in a one-dimensional homogeneous porous media involving the gravity effects is numerically studied using the dominant wave method. The paper aims to discuss these issues.

Design/methodology/approach
– The numerical scheme used for solving the pressure equations, obtained for the black-oil model, is a backward Euler scheme while the hyperbolic mass conservation equations, derived for both black-oil and Buckley-Leverett models, are solved using the dominant wave method. Higher-order schemes are achieved using either variable derivatives along with the minmod limiter or a MUSCL type interface construction scheme using the Fromm's limiter. The mass conservation equations are solved using the first-order forward Euler method in time. Harten's entropy correction procedure is employed to avoid non-physical expansion shocks.

Findings
– It was found that the dominant wave method can accurately solve multiphase flow equations involving gravity effects. Numerical experiments also show that both minmod and Fromm's limiters can be successfully used to construct higher-order schemes while the minmod limiter gives slightly more diffuse solutions.

Research limitations/implications
– The flow models considered here include two- and three-phase Buckley-Leverett and the black-oil models and the capillary effects are neglected.

Practical implications
– The proposed scheme can be efficiently used for solving problems involving non-convex flux functions especially those experienced during gravity drainage process in hydrocarbon reservoirs.

Originality/value
– To the best of authors knowledge, this is the first time that the dominant wave method has been used to tackle multiphase flow problems involving gravity effect.
Sourcing under supply disruption with capacity‐constrained suppliers
Authors: Ray Pritee , Jenamani Mamata 
Published: September 2013

PurposeThe paper proposes multi‐sourcing models for optimal order allocation in newsvendor setting under supply disruption with stochastic demand where suppliers are capacity constrained.Design/methodology/approachMathematical models are constructed to describe the stochastic single period two echelon supply chain. We first investigate the uncapacitated suppliers’ problem. Then capacity constraint is included in the model to study the effect on sourcing decision. A numerical example and its solution are included to illustrate the solution procedure. We find the solution using traditional optimization approach, genetic algorithm and simulation optimization approach.FindingsThe models capture the impact of disruption risk on optimal sourcing decision. When demand is highly uncertain the order should be place with the lowest cost suppliers in case of uncapacitated problem; whereas, it is to be appropriately split among a set of low‐cost suppliers in case of capacitated problem. Simulation optimization found to be the best solution approach for such problem.Research implications/limitationsThe model is applicable for a single period short‐life cycle product.Originality/valueThe models can be utilized for any number of suppliers. The numerical study illustrates the impact of probability of disruption, its consequences and cost of purchase on sourcing decisions.

Authors: Chakraborty Shibashish , Sengupta Kalyan 
Published: September 2013

PurposeThe study is designed to explore the drivers of customer satisfaction of leading mobile network providers in a high‐growth market like Kolkata a metropolitan city in India.Design/methodologyA framework was developed based on earlier study of eminent researchers pertinent to customer satisfaction of mobile network providers in Germany, France, Korea, Canada, the USA and Greece. The construct flexibility was considered as a new determinant for customer satisfaction. For this data were collected from 277 respondents and pertinent analysis were made using multivariate techniques.FindingsThe study finds that generic requirements, price, and flexibility are major drivers of customer satisfaction of mobile network providers and brand wise relevance of these key determinants.Research limitations/implicationsThe fixed line telephone directory was the sampling frame, and all the respondents considered in the survey had a fixed line but there are situations where customer subscribes only to mobile phones. It is also necessary to study other metropolitan cities of India to validate the results we have obtained for Kolkata. Originality/value – The current research has taken into account new driver of customer satisfaction in a high‐growth market and this is the first study on drivers of customer satisfaction of leading mobile network providers in the city of Kolkata, India.
The impact of job satisfaction, adaptive selling behaviors and customer orientation on salesperson's performance: exploring the moderating role of selling experience
Authors: Singh Ramendra , Das Gopal 
Published: September 2013

PurposeThe purpose of this paper is to investigate the moderating effects of selling experience on the relationship between job satisfaction and sales performance, customer orientation and sales performance, and adaptive selling behaviors and sales performance, taking the context of B2B insurance selling.Design/methodology/approachUsing a sample of 380 business‐to‐business insurance salespersons from an emerging market (India) to validate their model, the authors tested several hypotheses using structural equation modeling (SEM).FindingsThe results suggest that experience works with customer‐oriented selling in making the more experienced salespersons better performers. It was also found that for less experienced salespersons, the impact of job satisfaction on performance is weaker than for more experienced salespersons. In addition, it was found that more experienced salespersons' performance is better explained using job satisfaction and customer‐oriented selling rather than their adaptive selling behaviors.Research limitations/implicationsThe study contributes by explaining the mechanism for the above relationships. The study also contributes to knowledge by showing that more experience may not be always good for sales performance. Since the sample comes from an emerging market, the paper extends the knowledge from developed markets, and by testing in emerging markets.Practical implicationsThe managerial implications of this study lie in explaining those situations where experience can make salespersons more productive. The current sales literature on B2B selling contexts falls short of explaining this mechanism in salesperson performance.Originality/valueThis study contributes to knowledge uniquely by extending the body of empirical evidence that suggests that for experience, more is not always better. The study also shows that a more experienced salesperson does not improve his/her performance by adopting adaptive selling strategies. Such adaptive selling strategies are probably more suitable for younger salespersons, given different expectations from them by customers. For experienced salespersons, job satisfaction and customer‐oriented selling are more important than adaptive selling. This study explains the mechanism for the above relationships.
Uncovering Victoria's Secret
Authors: Hume Margee , Mills Michael 
Published: September 2013

PurposeGiven an increasingly volatile and competitive fashion environment, the purpose of this paper is to qualitatively explore current consumer behaviour and psychological perspectives of luxury in women's undergarment fashion purchasing, with specific examination of whether this under‐investigated area of discrete or inconspicuous fashion appraisal is consistent with other luxury purchases.Design/methodology/approachThe study employs an interesting methodological approach using multiple qualitative techniques including research interviews, group forums, and narrative capture, to investigate women's undergarment purchasing in a changing fashion environment in relation to the issues of branding, self‐image, perceived self‐image, motivational perspectives, and consumer behaviour, as identified by 119 female consumers aged between 18 and 60.FindingsThis study supports in part previous research that indicated consumer behaviour is determined by the congruency between the consumer's self‐image and the consumer's image of brands, although early research suggested this only applied to conspicuous products and social consumption. The current study confirms the self‐image link in the area of inconspicuous fashion, and strongly relates inconspicuous products consumed privately to self‐esteem and perceived sexy self.Practical implicationsThe findings indicate that for intimate apparel marketing to be effective and credible, the marketed fashion items, and actions taken by designers, and retailers need to be consistent with the consumer's personal style, value perceptions, and self‐image.Originality/valueThis research examines several neglected areas in fashion and consumption research, and contributes to our understanding of key motivational elements important in the consumption of inconspicuous fashion, and the relationship of self‐image to inconspicuous consumption.
Brand extensions
Authors: Hennigs Nadine , Wiedmann Klaus‐Peter , Behrens Stefan , Klarmann Christiane , Carduck Juliane 
Published: September 2013

PurposeAlthough the investigation of brand extension strategies has gained importance, existing research focusses primarily on consumer attitudes to brand extensions, and to date, little research has been made on the luxury market. Moreover, studies on the impact of brand extensions have been limited to explicit measurement methods. Therefore, the aim of this study is to provide new insights by focussing on the change of consumers’ brand perception related to downgrading and upgrading brand extensions strategies in the luxury market based on an implicit association test (IAT).Design/methodology/approachIn this exploratory study context of examining the spontaneous reaction time with reference to the luxury concept by confronting respondents with adequate verbal brand extension stimuli, a ST‐IAT was considered for the empirical tests of these hypotheses.FindingsThe study results give evidence that consumers’ perception of an upgrading or downgrading strategy of a brand varies in accordance to these hypotheses. Hence, the reaction time of the H&M subjects decreased after having read the upgrading stimulus whereby, in the case of Karl Lagerfeld, the ST‐IAT reaction times showed that the downgrading information resulted in a weaker association of Karl Lagerfeld with luxury.Originality/valueThe use of implicit measurement methods is becoming increasingly important for assessing consumer reaction to the new product line. Particularly, when luxury brands apply a downgrading strategy, the risks of possible damages to the core brand are much higher than in the case of an upgrade of a basic brand to the luxury or premium segment.
Can Islam and status consumption live together in the house of fashion clothing?
Authors: O’Cass Aron , Jin Lee Wai , Siahtiri Vida 
Published: September 2013

PurposeReligion is a significant force in the lives of many people, however; its role in fashion clothing consumption is still unclear. To expand the knowledge on this issue, the present study seeks to understand the role of religiosity in affecting status consumption and fashion consciousness (FC) among Generation Y Muslim consumers, specifically focussing on Iran.Design/methodology/approachA survey was designed and administered in Iran to a sample of 300 young adults aged between 18 and 24.FindingsThe findings of research show an inverse association between status consumption and religiosity, where individual's FC is contingent upon the degree to which they are status conscious or religious. The other major finding of the present study is the importance of brand status in mediating the relationship between FC and willingness to pay (WTP) a price premium for fashion clothing brands.Originality/valueThe originality of the study rests on exploring the moderating role of religiosity on the relationship between status consumption and fashion conscious among Iranian Generation Y Muslim consumers. Further, contrary to the belief that fashion conscious customers are willing to pay extra to obtain fashion brands, this relationship is not direct. New fashion conscious consumers pay extra provided that the new fashion brand enhances their status. Thus, the importance of status is in acknowledging the relationship between FC and WTP a price premium.
Luxury perceptions: luxury brand vs counterfeit for young US female consumers
Authors: Doss Farrell , Robinson Tammy 
Published: September 2013

PurposeThe purpose of this study is twofold: expand the body of empirical knowledge of consumer luxury brand perceptions by using the Brand Luxury Index (BLI) scale to compare and contrast young female consumers’ luxury perceptions for a luxury brand and counterfeits of that brand, and use the data from the research to investigate the psychometric properties of the BLI scale.Design/methodology/approachA convenience sample of 215 female students across multiple programmes of study completed separate, modified BLI scales for the luxury brand and the counterfeits of that brand. The BLI scale taps five dimensions or factors of brand luxury using non‐personal‐oriented perceptions and personal‐oriented perceptions.FindingsThis study used a modified version of the original BLI scale. Results show that all rated perceptions of the luxury brand were significantly higher than those for the counterfeits of that brand. Between‐subjects effects revealed that luxury perceptions of those whose last handbag acquisition was a luxury brand significantly differed from the luxury perceptions of those whose last handbag acquisition was a counterfeit brand. SEM results produced inadequate fit values for the luxury brand; but suggested adequate fit for the counterfeit of the luxury brand.Research limitations/implicationsAs more luxury brand producers and retailers seek to expand their presence on the world arena, brand equity may be compromised by making luxury brands so ubiquitous in the market place. Reported perceptions in this research suggest the market may be saturated with luxury brands and that luxury brands may be “overexposed”. Results from this study may only be applicable to young female college consumers. Also, since a particular luxury brand was used, results may not be generalized to other luxury brands. Additional research is needed that looks at other populations’ perception of luxury brands.Originality/valueNo research has been found that compared young consumer luxury perceptions for both luxury brands and their counterfeits. An investigation of this area would provide additional insight on consumer perceptions for luxury and counterfeit brands.
Corporate branding, emotional attachment and brand loyalty: the case of luxury fashion branding
Authors: Theng So Jing , Grant Parsons Andrew , Yap Sheau‐Fen 
Published: September 2013

PurposeThe purpose of this study is to develop and empirically test a theoretical framework that captures the impact of corporate branding on customer emotional attachment and brand loyalty in the luxury fashion market.Design/methodology/approachCross‐sectional data were collected from 282 customers who purchased luxury brands. Structural equation modelling was used to test the hypotheses of the framework developed for the study.FindingsFindings found limited effect of corporate branding on customer emotional attachment and brand loyalty. Among the six corporate branding dimensions examined, only corporate association, functional benefits, and symbolic benefits were found to have a significant impact on emotional attachment. Further, the impact of corporate branding on brand loyalty was only evident through functional benefits and corporate associations.Practical implicationsThis study offers new empirical support for the proposition that corporate branding efforts have a role, thought limited, in building customer emotional attachment and loyalty towards luxury brands. As such, findings from this study can provide managers with a guide to managing their branding strategies so that customer emotional attachment and brand loyalty can be built in the most cost‐effective manner.Originality/valueThis is the first study to examine the relationship between corporate branding, emotional attachment, and brand loyalty in the luxury fashion context. The examination of the differential effects of corporate branding dimensions on emotional attachment and loyalty has contributed to a better understanding of the mechanism that underlies the operation of an effective corporate branding strategy.
Supporting recovery in a third sector alternative to psychiatric hospital admission: evaluation of routinely collected outcome data
Authors: Larsen John , Griffiths Christopher 
Published: September 2013

Purpose
– To evaluate the impact of crisis house admission in terms of mental health recovery and achievement of personal goals for people using the service.

Design/methodology/approach
– Mental Health Recovery Star (Recovery Star) and Personal Goal Scoring data were collected at entry and exit points in routine practice as part of a bespoke support planning process from 722 adults using one of three Rethink Mental Illness Crisis Houses. The adults had mental illness diagnoses including depression, schizophrenia, bipolar disorder, personality disorder, and anxiety disorder.

Findings
– There were significant increases in all ten Recovery Star domains, for example: managing mental health (up 2.11 points (1-10 scale)), identity and self-esteem (up 1.56 points), trust and hope (up 1.48 points), and self-care (up 1.35 points). The analysis of Personal Goal Scoring data (scored on 1-10 scale) showed significant increases on how close people were to achieving their goals. For all goals listed there was an average increase of 2.5 point from 3 to 5.5, showing that people made progress during their stay in the service.

Practical implications
– Services provided by the third sector may offer an important contribution to support people's recovery and prevent admission to psychiatric hospital.

Originality/value
– The findings of the evaluation study support a growing body of evidence regarding the effectiveness of services offering alternatives to admission, and they highlight the value of using recovery-oriented support planning and outcome capture tools in routine practice.

Authors: Avci Gunes , Hanten Gerri , Schmidt Adam , Li Xiaoqi , Orsten Kimberley , Faber Jessica , Post Marina , R. Newsome Mary 
Published: September 2013

Purpose
– The study is a preliminary attempt to identify cognitive factors (e.g., executive functions and intelligence) promoting resilience in youth in an underprivileged population. Sample consisted of 26 adolescents (seven female, 19 male) between the ages of 13 and 19 years (M=16.62, SD=1.53) from an underserved population who live in circumstances of poverty and family dysfunction and who had experienced multiple traumas.

Design/methodology/approach
– Resilience was measured with the Child and Youth Resilience Measure (CYRM)-28. Intelligence, working memory, and information processing speed were the cognitive factors of interest. Socioeconomic status was the environmental factor in interest.

Findings
– The protective factors (i.e. individual skills, relationship with caregivers and contextual factors) promoting resilience were correlated with cognitive factors. Further analyses yielded gender differences in these relations.

Originality/value
– Long-held beliefs that intelligence is positively associated with resilience are brought into question by these findings. The relationship between these concepts seems to differ in accordance with socioeconomic status.
