Authors: Zhang Kai , Meng Qingfeng , Chen Wei , Li Junning , Harper Phil 
Published: September 2015

Purpose– This paper aims to measure the oil film thickness between the roller and the inner ring in roller bearings by the ultrasonic method. The oil film thickness between the roller and the inner ring in roller bearings is a key performance indicator of the bearing lubrication condition. As the oil film is very thin and the contact region is very narrow, measurement of this film thickness is very challenging. A promising ultrasonic method was used to measure this film thickness, and this method was expected to overcome some drawbacks in other methods.Design/methodology/approach– A simplified roller bearing only configured one roller, and an inner ring was built up to investigate this measurement. A miniature piezoelectric element is bonded on the inner surface of the inner ring to measure the reflection coefficient from the layer of oil between the roller and the inner raceway. As the width of the line contact region is smaller than the width of the piezoelectric element, a ray model is used to calibrate the reflection coefficient measured. The quasi-static spring model is then used to calculate oil film thickness from the corrected reflection coefficient data.Findings– The results measured by this method agree reasonably well with predictions from elastohydrodynamic lubrication (EHL) theory. Also, a dynamic displacement of the rig caused by the skid of the roller versus the inner ring was found under light-load and high-speed conditions.Originality/value– This work shows that the oil film between the roller and the inner raceway in roller bearings can be measured accurately by ultrasound and shows a deal method when the contact width is smaller than the piezoelectric element width.
Combined effects of piezo – viscous coupled stress lubricant and rotational inertia upon squeeze film performance of rough circular discs
Authors: Daliri M. , Jalali-Vahid D. 
Published: September 2015

Purpose
– The purpose of this paper is to investigate squeezing and rotating motions between two rough parallel circular discs lubricated by piezo – viscous couple stress lubricant with pressure-dependent viscosity variation.

Design/methodology/approach
– Based upon the Stokes couple stress theory, Barus viscosity-pressure dependency relation and Christensen rough surfaces model, squeeze film characteristics between two rough parallel circular discs are obtained.

Findings
– According to the results, it is found that, the combined effects of couple stresses and viscosity-pressure dependency increases squeeze film performance with respect to the classical Newtonian iso-viscous (constant viscosity) lubricant. However, increasing the rotational inertia parameter reduces squeeze film characteristics. On the other hand, depending on the structure of surface roughness, the squeeze film characteristics can be increased or decreased. Furthermore, results show that the surface roughness with circular pattern increases squeeze film characteristics, while the surface roughness with radial pattern will decrease it.

Originality/value
– This paper is relatively original and describes the squeeze film characteristics between two parallel circular discs with viscosity-pressure dependency, rotational inertia, couple stresses and surface roughness effects.

Authors: Padgurskas Juozas , Rukuiža Raimundas , Kupcinskas Arturas , Kreivaitis Raimondas 
Published: September 2015

Purpose
– The purpose of this paper is to conduct research on the possibility of improving the tribological and utilization properties of lard and rapeseed oil bio-based greases by mixing it with ethanol and selection of thickener and modification with special biological additives.

Design/methodology/approach
– Rapeseed oil- and lard-based greases with sodium and lithium soap thickeners were mixed with either water or ethanol and modified with a special biological anti-wear additive. Tribological properties of modified lubricants evaluated on a four-ball machine.

Findings
– Rapeseed oil- and lard-based greases suspended in ethanol and modified with bio-additive have the same wear resistance as the industrial non-biological lubrication grease and much higher wear resistance as bio-based reference grease. The tribological efficiency of the additives is higher in greases of rapeseed oil and less efficient in lard-based greases. Oxidation and wear tests show that investigated bio-based greases have comparatively stable tribological properties also after their aging. Modified greases have sufficient consistence according penetration measurements and high thermal resistance according drop-point temperature measurements. All produced experimental greases pass within the category of the easily degradable materials.

Originality/value
– The greases mixed with the ethanol make possible to form more homogeneous and stable grease mixture. Modified bio-based greases have significantly higher wear resistance as bio-based reference grease, their lubrication properties are stable also after the aging and are categorized as easily degradable materials.
Sustainability labelling as a challenge to legitimacy: spillover effects of organic Fairtrade coffee on consumer perceptions of mainstream products and retailers
Authors: Anagnostou Angela , Ingenbleek Paul T.M. , van Trijp Hans C.M. 
Published: September 2015

Purpose– This study aims to better understand the impact of norm-challenging products on consumers’ perceptions of mainstream products and retailers. By showing that sustainable market offerings are feasible, products with sustainability labels, such as Fairtrade and organic products, implicitly question the legitimacy of mainstream brands in the market.Design/methodology/approach– This paper uses an experiment, based on scenarios that portray the consumer in a shopping situation for their usual coffee brand when they encounter an organic Fairtrade coffee. The paper distinguishes a situation in which the sustainable and the mainstream products compete, from a situation in which the two brands collaborate.Findings– The results show that norm-challenging products deteriorate perceptions of mainstream products and the companies that produce them but improve the image of retailers that include these products in their assortment. If labelled products are sold under the heading of mainstream brands, they still spill over negatively to other products of that brand but positively to the brand company.Practical implications– The spillover effects of norm-challenging products to mainstream companies are an incentive for mainstream firms to enhance the sustainability of their activities.Originality/value– Whereas much literature has focused on the first steps of creating awareness among consumers for sustainability, this paper is the first that tries to understand how typical consumers of mainstream brands develop preferences for products that are more sustainable.
Satisfaction with service recovery: moderating effect of age in word-of-mouth
Authors: Moliner-Velázquez Beatriz , Ruiz-Molina María-Eugenia , Fayos-Gardó Teresa 
Published: September 2015

Purpose
– The purpose of this paper is, first, to analyze the direct effects of the relationship chain “causal attributions and recovery efforts → satisfaction with service recovery → conventional and online word-of-mouth intentions” and, second, to study the moderating role of age in the relationship between satisfaction and subsequent word-of-mouth. Consumer assessment and behavior associated with service recovery is a topic of considerable interest for both academics and practitioners.

Design/methodology/approach
– From an empirical perspective, this paper uses a sample of 336 individuals who experienced service failure at a retail store to estimate a structural equation model. Additionally, a multigroup analysis allows testing the existence of a moderating effect of age on the hypothesized relations.

Findings
– Results allow to confirm the direct effects of causal attributions and recovery efforts on satisfaction with service recovery, and the impact of the latter, in turn, on conventional and online word-of-mouth intentions. Furthermore, the multigroup analysis reveals that age moderates the relationship between satisfaction and online word-of-mouth.

Practical implications
– In service recovery situations, retailers should concentrate their efforts at providing evidence of the failure as temporary and inevitable as well as offering material or economic compensation.

Originality/value
– This paper contributes to the identification of the most relevant variables influencing customer satisfaction with service recovery in a retail context. In addition to this, these results provide support to the importance of age on online word-of-mouth behavior.

Authors: Cheah Isaac , Phau Ian , Chong Calvin , Shimul Anwar Sadat 
Published: September 2015

Purpose
– The purpose of this paper is to investigate the influence of brand prominence on willingness to buy luxury brands. It also aims to investigate the direct and moderating roles of luxury brand values, social influence and vanity on willingness to buy luxury brands.

Design/methodology/approach
– A convenience sampling method was employed. Survey questionnaires were distributed by mall intercept to quasi-random samples in downtown Perth, Western Australia for completion and return. The return yielded 779 usable questionnaires, the data from which were analysed using SPSS 22.

Findings
– The findings support the influence of brand prominence on purchase intention for luxury brands. It has also been found that social influence has a significant influence on physical vanity and willingness to buy luxury brands. However, some relationships with and isolations from the earlier studies have been identified.

Practical implications
– This study provides some meaningful insights for marketing managers regarding brands prominence that they can use in better understanding the consumers’ intention to buy luxury products. A luxury goods manufacturer may want to be cautious to not over popularize its trademark for short-term gains. There must be a delicate balance between the uses of prominent and subtle signals in luxury branding in order to maintain value as a prestigious label.

Originality/value
– Previous studies have mainly focused on the antecedents of willingness to buy luxury brands, whereas this paper incorporates the construct of brand prominence, adding new insights into the construct.
Brand luxury index: a reconsideration and revision
Authors: Kim Jieun , Johnson Kim K. 
Published: September 2015

Purpose– The purpose of this paper is to improve the original Brand Luxury Index (BLI) developed by Vigneron and Johnson to provide a practical tool for assessing consumer’s perception of the luxurious of a brand.Design/methodology/approach– The original BLI was revised through three stages: an initial scale-item generation employing a qualitative method (i.e. focus group interviews), scale purification process using statistical techniques (i.e. exploratory factor analysis and confirmatory factor analysis (CFA)), and scale verification process using CFA. Data (249 for scale purification, 253 for scale validation) were collected with the help of E-rewards, a marketing research company.Findings– The modified BLI contains five dimensions (i.e. quality, extended-self, hedonism, accessibility, and tradition). The number of the dimensions remained the same as the original conceptualization (i.e. conspicuousness, uniqueness, quality, hedonism, extended-self), however, the contents of those dimensions differed.Practical implications– The modified BLI can be used to monitor and manage a prestige brand in the market place. Not only can marketers of prestige brands use the index to assess consumers’ perception of the luxuriousness of their brands but also to position their brand along the desired dimension of luxuriousness.Originality/value– The modified BLI can be used to measure marketing performance of luxury brands.
Web atmospheric qualities in luxury fashion brand web sites
Authors: Kim Hyeonsoo , Choi Yun Jung , Lee Yuri 
Published: September 2015

Purpose– The purpose of this paper is to explore the relationship between atmospheric qualities with different levels of task relevance in luxury fashion brand web sites and their impact on consumer attitude toward the site and brand, which is essential to build valid strategies for e-retailing.Design/methodology/approach– An empirical study was conducted and quantitative analyses of 292 respondents’ shopping experiences yielded findings that confirm the impact of atmospherics upon the shopper’s views of the web site and the brand. Structural equation modeling was used to test the research hypotheses.Findings– Both low task-relevant atmospherics (web site design, responsive customer service) and high task-relevant atmospherics (product information, convenience) affect the consumers’ revisit intentions toward the web site, while web site design directly affected brand attitude. The study also illustrates the mediating roles of product information and convenience to the relationships between web site design and responsive customer service and the consumers’ revisit intentions toward the site.Practical implications– This study provides insights for luxury e-tailing. Luxury e-tailers should understand the different effects depending upon the types of web atmospheric qualities and use them strategically.Originality/value– The main contribution of the study is to highlight the unique aspects of luxury online shopping in the Korean context. This study also contributes to e-commerce research by providing an expanded understanding of the interrelationship between types of web atmospheric qualities.
Online behaviour of luxury fashion brand advocates
Authors: Parrott Guy , Danbury Annie , Kanthavanich Poramate 
Published: September 2015

Purpose
– Over the past few years online fashion communities have proliferated becoming an increasingly powerful forum for user-generated content, and consequently, the fashion industry has shown great interest in such communities. The purpose of this paper is to review and analyse brand advocacy behaviour within luxury brand accessory forums: to analyse the role these communities play in influencing purchase intention; assessing their contribution to fashion brand love.

Design/methodology/approach
– The study adopted a netnographic approach to the phenomenon of online luxury accessory communities. The research reports observational data including blog texts and audience comments for four popular forums: The Purse Forum, The Fashion Spot, The Bag Forum (TBF) and Shoe Forum (SF). Although the forums are open to all and are designed to be internationally relevant; the observations were conducted from a base in the UK.

Findings
– Findings indicate that informants display some unifying characteristics clustered around engagement, involvement, self-concept and self-connection, brand love and hedonic values. Informants however, display some discernible differences as they “rally” to two distinctive totems: first, active luxury brand advocates and second, passive brand advocates. Although subtle, these differences suggest significant possibilities for fashion brand owners.

Research limitations/implications
– Further research could include the measurement of brand advocacy to distinguish more clearly between high and low levels of advocacy and the resulting consumer behaviour intentions. One sub-group that would be interesting to explore is that of brand evangelists and their relationship with fashion brands: what are the reasons for treating brands as religious artefacts and can this extreme level of advocacy be developed by marketing? The study focused on observing online posts by self-selected brand advocates. A worthwhile comparison could be made with fashion communities where brand marketers are active participants and how this influences the discourse and actions of brand advocates.

Practical implications
– The findings indicate that all forum members are incredibly attached to their brands, but will still consider purchasing several brands as their “evoked set”. Additionally, even when demonstrating involvement, they can operate as passive observers in the online community.

Originality/value
– Social media, especially online forums, play an important role in contemporary luxury fashion branding. This study addresses the role these forums play in supporting brand love and the contribution they make to luxury brand advocacy. Membership and influence dynamics are reported; which have resonance to both practitioners and researchers.
Luxury consumption moves East
Authors: Khan Omera 
Published: September 2015

Purpose– The literature contains relatively little prescriptive guidance for establishing supply chain strategies in the luxury fashion marketplace. The focus has been on fashion rather than luxury fashion and the purpose of this paper is to identify and explore the critical supply chain success factors to consider when entering the Chinese luxury fashion marketplace.Design/methodology/approach– Given the lack of research in this area an exploratory and in-depth case study was conducted with a niche UK textile manufacturer.Findings– Findings from the case study suggest there are four critical success factors to consider when developing a business strategy to enter the Chinese luxury fashion marketplace.Practical implications– The findings could guide managers that are developing a business case for entering the Chinese luxury fashion marketplace.Originality/value– This case study provides novel insights to transformations in global supply chain strategy as luxury consumption is moving towards the east, which creates new challenges and demands for European manufacturers to respond, to sustaining a competitive advantage.
The use of section 135(1) of the Mental Health Act in a London borough
Authors: Watson James , Daley Stephanie 
Published: September 2015

Purpose
– The purpose of this paper is to determine the incidence of the use of section 135(1) of the Mental Health Act 1983 in a London borough and describe the main features of the population subject to that section.

Design/methodology/approach
– Uses of section 135(1), hospital stay, and demographic data were gathered from service and patient records over one year. Means, medians, modes and standard deviation were calculated for interval data. Nominal data were cross-tabulated and the chi square test applied where appropriate. Study data were compared to census and national hospital data; the significance of proportional population differences were calculated using the Z-test.

Findings
– In total, 63 uses of section 135(1) were recorded. It was primarily used with people with psychotic diagnoses (79 per cent), and was used predominantly in black populations, and among people aged 40-54. People admitted to hospital after section 135(1) use who had psychosis diagnoses had median spells in hospital that were double the corresponding national median.

Research limitations/implications
– Total uses of section 135(1) in the borough equated to 25 per cent of the national total for all section 135 admissions recorded in 2012/2013. Hospital statistics in England focusing on admissions alone may fail to reflect a more widespread use of this section. Further research is required to confirm and develop the findings of this small scale study.

Practical implications
– The repeated use of this section is suggested as a marker for reviewing practice and resource allocation to prevent or shorten hospital admissions for people with psychosis diagnoses.

Originality/value
– This paper highlights gaps in NHS data collection in England relevant to policy makers, mental health service providers, and the police service.
Doing and rethinking. Building resilience with men
Authors: Robinson Mark , Robertson Steve , Steen Mary , Raine Gary , Day Rhiannon 
Published: September 2015

Purpose
– The purpose of this paper is to present findings from an evaluation of a mental health resilience intervention for unemployed men aged 45-60. The focus is on examining the place of activities within a multi-dimensional men’s mental health programme, and exploring interactions between social context factors and models of change.

Design/methodology/approach
– The paper draws on before and after survey data and qualitative interviews, to report results concerning effectiveness in changing men’s perceived resilience, to consider project processes concerning activities, social support and coping strategies, and to situate these within wider environments.

Findings
– The programme significantly raised the perceived resilience of participants. Activities were engaging for men, while the complex intersection between activities, social networking, and coping strategies course provided opportunities for men to develop resilience in contexts resonant with their male identities.

Research limitations/implications
– A limitation is that the evaluation could not measure longer term impacts.

Practical implications
– The paper discusses emerging considerations for resilience building, focusing on gender-sensitive approaches which can engage and retain men by focusing on doing and talking, in the contexts of men’s life-course, highlighting embodied (male) identities not disembodied “mental states”, and facilitating social support. There are challenges to recruit men despite stigma, support men to speak of feelings, and facilitate progression.

Social implications
– Potential exists for gender-aware programmes to sustain salutogenic change, co-producing social assets of peer support, male-friendly activities, and context sensitive course provision.

Originality/value
– The paper adds fresh evidence of gendered intervention approaches, including effects on male resilience. Application of a context-sensitive change model leads to multi-component findings for transferring and sustaining programme gains.
Power and logics in Scottish football: the financial collapse of Rangers FC
Authors: Morrow Stephen 
Published: September 2015

Purpose– The purpose of this paper is to demonstrate the implications of power imbalance and over-emphasis on commercial logic on the structure and governance of Scottish football.Design/methodology/approach– An in-depth analysis of secondary sources is used to identify the logics at play in Scottish football and to explore implications of the liquidation of Rangers for the structure of the game.Findings– Over-emphasis on commercial logic has led to power being concentrated in two clubs, Celtic and Rangers, and to other clubs and the league itself becoming financially dependent on those clubs. The collapse of Rangers thus threatened the stability of other clubs and the league. The case highlights the challenge of reconciling competing logics and the role played by previously peripheral actors in bringing about change in the field.Research limitations/implications– The on-going nature of the case, related investigations and legal process meant that it was not possible to supplement the secondary source material with primary evidence.Practical implications– It demonstrates the multi-faceted nature of elite contemporary football and of the challenges faced by leagues and governing bodies in accommodating logics and multiple stakeholder interests. It also highlights the need for more effective financial regulation of corporate football clubs and their officials and emphasises the importance of inclusive stakeholder governance.Originality/value– It highlights the risks inherent in football business in small markets dominated by one or a few clubs. It highlights the role that previously peripheral actors can play in bringing about change within a field.
