Reducing transportation emissions
Authors: Pålsson Henrik , Kovács Gyöngyi 
Published: May 2014

Purpose
– The purpose of this paper is to evaluate why companies reduce transportation emissions by examining the relative importance of external drivers vs internal motives for companies in considering CO2 emissions in freight transportation.

Design/methodology/approach
– A framework is suggested that captures internal, competitiveness-driven motives and external, stakeholder-driven drivers for companies seeking to reduce CO2 in freight transportation. These factors are tested in a large industry survey in Sweden. The survey resulted in 172 responses from corporate heads of logistics, a response rate of 40.3 per cent.

Findings
– Variations in responding to stakeholder pressure vs company strategy for reducing transportation emissions are identified. Company strategy outweighs stakeholder pressure in determining whether a company intends to green its transportation. The strategy leads to company-internal motives for reducing transportation emissions which differ from company to company. These differences, in turn, lead to different levels of intended reductions. Stakeholder pressure sets the minimal levels that elevate the performance of a group of companies in an industry or a country, but the differentiation effect across companies is lost. The intention to reduce emissions is greatest if a company has both economic and image motives. The logistics resource configuration does not seem to impact drivers and motives.

Research limitations/implications
– The research is based on companies in Sweden. Studies across several countries are needed to investigate the impact of national requirements.

Originality/value
– The paper shows that the combination of the resource-based view and stakeholder theory presents a better explanation as to why companies reduce transportation emissions than either of them do separately. By combining the two theories this research differentiates between how stakeholder pressure and company strategy influence intents to green transportation.

Authors: Zuber-Skerritt Ortrun , Cendon Eva 
Published: May 2014

Purpose
– The aim of this paper is to present an interview and postscript that examine the specific meaning, rationale, conceptual framework, assessment and teaching of critical reflection in and on professional development in management and higher education from an action research perspective.

Design/methodology/approach
– This article is presented in the new genre of PIP (Zuber-Skerritt, 2009): Preamble – Interview – Postscript. The Preamble (P) sets out the background, purpose, structure and conduct of the interview (I), which addresses six probing questions and is followed by a Postscript (P) that reveals additional comments and reflections on the interview, and identifies learning outcomes and implications.

Findings
– Reflective practice is essential for a deep approach to learning, research and professional development and it is a driving force to enable learners to be adequately equipped for constant and complex change in today's and tomorrow's turbulent world.

Research limitations/implications
– The article is positioned to inspire further R&D in the current debate on urgently needed radical and rapid change in higher education for the twenty-first century.

Practical implications
– As well as the article's practical suggestions about why and how to develop reflective learning/practice, the PIP conceptual model applied in this article offers a useful practical approach for researchers to explore self-ethnography through interviews.

Originality/value
– Two conceptual models illustrate the essence of this article, providing practical help to academics and other professionals to advance reflective practice in research and learning.
Young consumers' innovativeness and hedonic/utilitarian cool attitudes
Authors: Noh Mijeong , Runyan Rodney , Mosier Jon 
Published: May 2014

Purpose
– This study aims to investigate the relationship between young consumers' innovativeness and their hedonic/utilitarian attitudes toward cool clothing and to examine the moderating role of income on this relationship. This study uses five cool factors (singular cool, personal cool, aesthetic cool, functional cool and quality cool) under the hedonic and utilitarian cool dimensions to test the hypotheses.

Design/methodology/approach
– Using a web-based survey, 265 responses were used for analysis. A confirmatory factor analysis was conducted to assess the measurement scales. Single-group SEM and multiple-group SEM were performed to examine the hypothesized relationships.

Findings
– Innovative young consumers tend to have stronger hedonic cool attitude toward clothing than non-innovative young consumers. In contrast, innovativeness and utilitarian values of cool products are not interrelated for young consumers. Innovative, high-income young consumes have a tendency to purchase cool products to reflect their personality, individuality, and self-identity.

Research limitations/implications
– This study has limitations for future research with regard to the generalization of the findings because this study focused on a sample of college students.

Practical implications
– This study will provide some valuable information about young consumers' purchasing behaviours toward cool products for commercial marketers.

Originality/value
– This study provides an initial contribution to the literature on the relationships between young consumers' hedonic/utilitarian attitudes and their innovativeness and income levels.
Evolution of the lubrication regime of a cylindrical journal bearing in the starting phase
Authors: Mehala Kadda , Bendaoud Nadia , Youcefi Abdelkader 
Published: May 2014

Purpose
– The paper aims to analyze the evolution of the lubrication regime by studying the variation of friction coefficient with the rotational speed of the shaft and the impact of the applied load in the starting phase of a cylindrical journal bearing. The paper also aims to ensure that the oil layer is large enough for the rough edges of the outer layer of the bushing and the shaft cannot come into contact. The bearing is made of steel backing material and babbitted (88 per cent tin) on its inner surface.

Design/methodology/approach
– A numerical analysis is performed taking into account the thermal effect to better predict the operating performance of a hydrodynamic plain cylindrical journal bearing during the start-up and observe the variation of the heat production in bushing inner surface. The flow is modeled based on the Reynolds equation and discretized using the finite volume method.

Findings
– The evolutions of the start-up speeds of the bearing have remarkable influence on friction torque; average temperature and dissipated power increased with increasing speed and increasing load, but the maximum pressure and the eccentricity decreased with the increase of the start-up speed. The friction coefficient, minimum film thickness and attitude angle increase with elevation of start-up speed.

Originality/value
– For the start-up speed of 750, 1,000 and 1,800 rpm and an applied load of 1,000 N, the regime of lubrication of the bearing passes the hydrodynamic regime to the mixed regime; therefore, during start-up and under heavy loads, the bearing must move very quickly at these speeds to avoid contact of the inner surface of the bearing and the shaft.
Effects of lubricant on the mechanical properties of aluminum 6063 alloy after ECAE
Authors: S. Ajiboye Joseph , A. Adebayo Saheed , M. Azeez Temitayo 
Published: May 2014

Purpose
– The purpose of this paper is to investigate the degree of improvement in mechanical properties of aluminum alloy (AA6063) after processing with equal channel angular extrusion (ECAE) using four environmentally benign lubricants.

Design/methodology/approach
– Aluminum (Al) 6063 bar was annealed at 350°C for 1 hour, machined and cut to billets measuring 14 × 14 × 44 mm3. These specimens for extrusions were machined to the specified dimension to a visibly good finish. The billets were extruded through ECAE die of 14 × 14 mm2 channel cross-section area; the channel angle was 120°; and the angle of the outer arc of the channels was 30°. The punch and container used for the experiment were made of tool steel alloy AISI D2, and were chromium-coated and polished. Four lubricants such as palm, olive, coconut and groundnut oils were used in this study.

Findings
– The yield, ultimate tensile strengths (UTS) and the ductility of the material ECAEed with palm oil as lubricant, which gave the least extrusion pressure, produces the maximum yield, UTS and ductility, followed by groundnut oil and coconut oil, while olive oil gave the least yield strength, (UTS) and ductility. However, palm oil and olive oil have better load reduction than other lubricants. Furthermore, from the hardness results, though scattered, all of the points at the tensile strained side of the extrudate lie within a reasonably narrow band, suggesting a high degree of homogeneity and greater hardness value within the rod than the compressive side after being ECAEed.

Originality/value
– It is shown in the paper that all the lubricants tested greatly enhanced mechanical properties of Al 6063 and can effectively replace the petroleum-based lubricants used in forging operations.

Authors: Unal Huseyin , Hakan Yetgin Salih , Findik Fehim 
Published: May 2014

Purpose
– The purpose of the study was to find the best performance polymer material to be used in railway car bogies.

Design/methodology/approach
– Wear tests and optical and scanning electron microscopy were used.

Findings
– The friction coefficients of ultra-high-molecular-weight polyethylene (UHMWPE) and Nylon 6 polymers, as opposed to AISI 4140 steel, reduced with the increment of applied loads. With the increment of sliding speed, the friction coefficient increased in both UHMWPE and Nylon 6 polymers. The specific wear rate of the UHMWPE polymer was determined to be about 10-14 m2/N, whereas the rate of Nylon 6 was determined to be 10-13 m2/N.

Practical implications
– The aim of the study was to find the best performance polymer material to be used in railway car bogies.

Originality/value
– The friction and wear performance of UHMWPE and Nylon 6 engineering polymers were studied and compared to their AISI 4140 steel counterparts. It is an original work and it is not published in any media.
A novel benztriazole derivative for enhancing the anti-oxidation properties of synthetic ester-based oils
Authors: Zhao Gaiqing , Zhao Qin , Wang Xiaobo , Liu Weimin 
Published: May 2014

Purpose
– The purpose of this paper is to study a novel Mannich adduct of benztriazole-containing diphenylamine (coded as BD) and its anti-oxidation properties as an additive in two typical synthetic ester-based oils.

Design/methodology/approach
– The anti-oxidation properties in two typical synthetic ester-based oils were evaluated in detail, using rotating pressure vessel oxidation test. The tribological properties of BD in synthetic ester-based oil (A51) were also tested with Optimal SRV-I oscillating friction and wear tester at atmosphere.

Findings
– The results of tests demonstrated that the novel BD compound is, indeed, a high-performance anti-oxidation additive that was able to remarkably improve the oxidation stability of synthetic ester-based oils, when it was added at only 0.5 per cent concentration and compared with the base oils containing 0.5 per cent of the commercial available antioxidant additives such as 2, 6-di-tert-butyl-4-methylphenol and octyl-butyl diphenylamine. A plausible mechanism of exceptional synergistic anti-oxidation was proposed.

Originality/value
– This paper first investigated the anti-oxidation properties and mechanisms of the compound with the structure of BD, which can be very useful and would promote the application of BD antioxidant in the lubricant industry.

Authors: Keng Ching-Jui , Tran Van-Dat , Liao Tze-Hsien , Yao Chao-Ju , K. Hsu Maxwell 
Published: May 2014

Purpose– The purpose of this paper is to explore the impact of the sequential combination of consumer experiences on product knowledge and brand attitude. Additionally, the moderating role of desire for unique consumer products (DUCP) was also discussed.Design/methodology/approach– Four types of sequential combinations of consumer experiences were designed: exposure to escapist virtual experience preceding direct experience (VEescapist→DE), exposure to education virtual experience preceding direct experience (VEeducation→DE), exposure to escapist virtual experience preceding indirect experience (VEescapist→IDE), and exposure to education virtual experience preceding indirect experience (VEeducation→IDE). A total of 302 undergraduate college students in Taiwan participated in this study.Findings– The results revealed that DUCP moderated the sequential combination of consumer experiences on product knowledge. For the high level of DUCP, there are significant differences among the effects of the sequential combination of consumer experiences on product knowledge. Specifically, it was found that VEescapist→IDE produces the highest product knowledge while VEeducation→DE produces the lowest product knowledge. Regarding the low level of DUCP, there are not significant differences among the effects of sequential combination of consumer experiences on product knowledge.Originality/value– This study extended the studies of Daughertyet al.(2008), Pine and Gilmore (1999), and Kenget al.(2012) to further explore the effects of the sequential combination of experiences.
Adoption readiness, personal innovativeness, perceived risk and usage intention across customer groups for mobile payment services in India
Authors: Thakur Rakhi , Srivastava Mala 
Published: May 2014

Purpose– The purpose of this paper is to accomplish two objectives – to test the functional relationship between adoption readiness (AR), perceived risk (PR) and usage intention for mobile payments in India and to investigate the stability of proposed structural relationships across different customer groups.Design/methodology/approach– The literature concerning major attributes of technology acceptance were systematically reviewed to develop construct of AR. Post that a comprehensive model consisting of AR, personal innovativeness and PR was put together. The model was then empirically tested using structural equation modelling.Findings– On appraising the proposed model, five out of six hypotheses were fully supported while one hypothesis was partially supported. Test of invariance showed significant variance among users and non-users.Research limitations/implications– The results of the study may vary with national context, service offerings, regulatory framework and other customer personal variables (i.e. lifestyle) suggesting future research opportunities.Practical implications– The results facilitate the comprehension of the role of different factors on the mobile payments usage intention among customers. In addition, the results expand the knowledge on consumer behaviour towards financial technological innovations.Originality/value– The results expand one's knowledge on this relationship, propounding interesting empirical evidence of the model invariance among different consumer groups.
Nature and duration of the accounting differences between Italian and US GAAP
Authors: Mura Alessandro , Roberto Gianluigi 
Published: May 2014

Purpose
– The purpose of this paper is to focus on alternative accounting treatments over time to assess their impact on the level of conservatism in a comparison between Italian local accounting standards and USA generally accepted accounting principles.

Design/methodology/approach
– A case study approach is adopted to investigate the accounting adjustments applied to net income and shareholders’ equity as included in the Form 20-F reconciliations reported by all Italian firms that were listed on a US market over the period 1999-2008. The methodology first introduced by Gray (1980) and frequently applied over 30 years to several international accounting comparisons is adapted to recognise a multi-period dimension of the accounting choice. In particular, the paper focuses on the temporal dimension of such adjustments in order to capture their attitude to reverse or become permanent over time.

Findings
– The results show that the level of conservatism is visible in the measurement of net assets and is shaped by the prevailing directional effect of accounting adjustments that become permanent as their cumulative reversal is persistently delayed. Such a phenomenon arises and intensifies when the accounting differences relate to recurring operations and/or to long-term assets and liabilities. Amongst them those violating the clean surplus relation are the most controversial as they not only generate a permanent effect in the measurement of net assets, but also an opposite permanent effect in the measurement of earnings.

Research limitations/implications
– Future empirical research confirming the finding in different contexts might overcome the limitations of a relatively poor number of observations in the case study.

Practical implications
– Identifying the duration of alternative accounting treatments is relevant to assess their potential influence on stakeholders decision-making process as this may steadily influence the future of a firm.

Originality/value
– The propositions express a sequence of the timing effects of alternative accounting treatments that highlight the primary role of permanent differences in persistently shaping the value of net assets and help to provide a less erratic interpretation of the level of conservatism.

Published: May 2014

Purpose
– The purpose of this paper is to extend a routing model so that it may be applied to a real case study of material deliveries involved in a development operation, typical of regular humanitarian logistics, and to explore the impact of variations in available logistic assets.

Design/methodology/approach
– The introduced model is a conceptual evolution of the study recently presented. It concerns the resource allocation and vehicle routing decisions in the well-known Haitian case. Different scenarios are analyzed and a sensitivity analysis is provided. Constraints related to transportation resources in a complex environment, transportation vehicle capacities, and delivery time restrictions are here considered.

Findings
– This research shows how the logistic assets characteristics and their availability affect the distribution system performances, in terms of total distribution cost and shortages.

Originality/value
– The present work explores the last mile distribution problem by providing a case study to assist decision makers in making effective and efficient distribution across the last mile. The research focusses upon the distribution systems management coupled with material distribution modalities.
Social prescription and the role of participatory arts programmes for older people with sensory impairments
Authors: Vogelpoel Nicholas , Jarrold Kara 
Published: May 2014

Purpose– The purpose of this paper is to describe the benefits of a social prescribing service for older people with sensory impairments experiencing social isolation. The paper draws on the findings from a 12-week programme run by Sense, a voluntary sector organisation, and illustrates how integrated services, combining arts-based participation and voluntary sector support, can create positive health and wellbeing outcomes for older people.Design/methodology/approach– The research took a mixed-methodological approach, conducting and analysing data from interviews and dynamic observation proformas with facilitators and quantitative psychological wellbeing scores with participants throughout the course of the programme. Observations and case study data were also collected to complement and contextualise the data sets.Findings– The research found that participatory arts programmes can help combat social isolation amongst older people with sensory impairments and can offer an important alliance for social care providers who are required to reach more people under increasing pecuniary pressures. The research also highlights other benefits for health and wellbeing in the group including increased self-confidence, new friendships, increased mental wellbeing and reduced social isolation.Research limitations/implications– The research was based on a sample size of 12 people with sensory impairments and therefore may lack generalisability. However, similar outcomes for people engaging in participatory arts through social prescription are documented elsewhere in the literature.Practical implications– The paper includes implications for existing health and social care services and argues that delivering more integrated services that combine health and social care pathways with arts provision have the potential to create social and medical health benefits without being care/support resource heavy.Originality/value– This paper fulfils a need to understand and develop services that are beneficial to older people who become sensory impaired in later life. This cohort is growing and, at present, there are very few services for this community at high risk of social isolation.
Time series trending for condition assessment and prognostics
Authors: Mosallam Ahmed , Medjaher Kamal , Zerhouni Noureddine 
Published: May 2014

Purpose
– The developments of complex systems have increased the demand for condition monitoring techniques so as to maximize operational availability and safety while decreasing the costs. Signal analysis is one of the methods used to develop condition monitoring in order to extract important information contained in the sensory signals, which can be used for health assessment. However, extraction of such information from collected data in a practical working environment is always a great challenge as sensory signals are usually multi-dimensional and obscured by noise. The paper aims to discuss this issue.

Design/methodology/approach
– This paper presents a method for trends extraction from multi-dimensional sensory data, which are then used for machinery health monitoring and maintenance needs. The proposed method is based on extracting successive features from machinery sensory signals. Then, unsupervised feature selection on the features domain is applied without making any assumptions concerning the source of the signals and the number of the extracted features. Finally, empirical mode decomposition (EMD) algorithm is applied on the projected features with the purpose of following the evolution of data in a compact representation over time.

Findings
– The method is demonstrated on accelerated degradation data set of bearings acquired from PRONOSTIA experimental platform and a second data set acquired form NASA repository.

Originality/value
– The method showed that it is able to extract interesting signal trends which can be used for health monitoring and remaining useful life prediction.
