Measures that matters: service quality in IT service management
Authors: Cronholm Stefan , Salomonson Nicklas 
Published: March 2014

Purpose
– IT service management (ITSM) is a discipline for management and maintenance of IT-systems and is claimed to play a critical role in supporting and satisfying business requirements. However, from a customer perspective, ITSM is considered as being costly and the outcome is not always satisfactory. Measurements used to monitor and evaluate ITSM-processes are mainly suggested from a service provider perspective. The purpose of this paper is to suggest measurements for ITSM based on a customer perspective that can be used for improving questionnaires.

Design/methodology/approach
– The SERVQUAL scale has been used as a base for suggesting customer-oriented measurements for the ITSM-field. The gathered qualitative empirical data consisted of customer feedback, in questionnaires, to five IT service providers in Sweden. Based on these empirical data, the SERVQUAL scale has been modified according to ITSM-specific customer requirements. The service providers represent the sectors: car construction, forest management, IT consultants, public sector and logistics.

Findings
– The paper demonstrates three types of findings: confirmation of original SERVQUAL determinants that could be reused in the ITSM-field, modification of attributes of the SERVQUAL determinants to better fit in the ITSM-field, and development of new categories and new attributes. Moreover, the analysis of SERVQUAL in relation to the empirical data revealed that the SERVQUAL's original conceptual structure needed to be improved. The authors have added a third hierarchical level that supports a conceptual understanding.

Originality/value
– The knowledge contribution consists of a developed SERVQUAL, adjusted to fit the ITSM-field, and a suggested new conceptual structure of SERVQUAL consisting of three concepts: determinant, category and attribute.
Experimental studies on the tribological behaviour of engine oil (SAE15W40) with the addition of CuO nanoparticles
Authors: V. Thottackkad Manu , Rajendrakumar P.K. , Prabhakaran Nair K. 
Published: March 2014

Purpose
– This manuscript aims to deal with the tribological property variations of engine oil (SAE15W40) by the addition of copper oxide (CuO) nanoparticles on weight percentage basis.

Design/methodology/approach
– Experimental studies on the influence of CuO nanoparticles utilised as an additive in lubricating oil (SAE15W40) under boundary lubrication conditions have been carried out using a pin-on-disc machine in accordance with ASTM G-99 standard. The variation of viscosity, coefficient of friction, wear and settling of nanoparticles has been studied as a function of particle concentration in the lubricant.

Findings
– Results show that the frictional force and specific wear rate decrease with an increase in concentration of nanoparticles comes to a minimum at a specific concentration and then increases, showing the presence of an optimum concentration. With the increase in concentration of nanoparticles, the kinematic and dynamic viscosities, and the flash and fire points are found to increase.

Originality/value
– The use of CuO nanoparticles as additives to a moderate level is a very efficient means of improving the tribological properties of lubricating oils.
The influence of tool kinematics on surface texture, productivity, power and torque of normal honing
Authors: Vrac Damir , Sidjanin Leposava , Balos Sebastian , Kovac Pavel 
Published: March 2014

Purpose
– In this paper, the influence of cutting regimes on surface texture and productivity of cylinder liner is shown, obtained by normal honing. Furthermore, normal honing power and torque is discussed. The paper aims to discuss these issues.

Design/methodology/approach
– Normal honing was done on grey cast iron cylinder liners. Both pre- and finishing honing were done by mechanical means, to achieve the required level of surface texture quality, traditionally achieved by a combination of electrochemical pre-honing and mechanical finishing honing. To determine the most influential parameter on normal honing, statistical mathematical model was devised. Surface texture was controlled by light microscope and scanning electron microscope.

Findings
– Mathematical model describing the influence of cutting speed, feed rate and depth of cut has shown that the most influential parameter on maximum peak height, productivity and specific volume productivity was shown. The most influential parameter has shown to be cutting speed.

Practical implications
– There are two practical implications of this work: this work is a further contribution of understanding normal honing and the influence of various parameters on the quality of normal honing, both in view of surface texture and productivity, as the main drawback of this method. This work offers useful information for honing system designers, as torque and power of normal honing are given.

Originality/value
– Two main achievements are given in this paper: as the main drawback of normal honing is lower productivity, the optimization of honing parameters may to some extent resolve this problem. Lower productivity is the result of lower cutting speeds and pressures, which in turn, give normal honed surface a higher quality compared to plateau honing. Lower power and torque demand a lower energy demands, as well as a less complex honing machine which may lead to further savings.
Experimental and numerical study on water-lubricated rubber bearings
Authors: Wang You-Qiang , Shi Xiu-Jiang , Zhang Li-Jing 
Published: March 2014

Purpose
– Water-lubricated rubber bearing is one of the most appropriate bearings for underwater use. The most popular design used widely today is the straight fluted rubber bearing. The special configuration leads to partial hydrodynamic lubrication and low load capacity. A new bearing bush structure with two cavities which is favorable for constructing continuous hydrodynamic lubrication was designed and studied. The paper aims to discuss these issues.

Design/methodology/approach
– A new bearing bush structure with two cavities which is favorable for constructing continuous hydrodynamic lubrication was designed. The apparatus for studying the tribological behaviors of the two types of water-lubricated rubber bearings has been devised and established in the paper. The experimental studies on the tribological properties of the rubber bearings have been conducted under different loads and velocities. The eccentricity ratio of the new structure rubber bearing with two cavities was measured in experiment and the load capacity was calculated by numerical simulation.

Findings
– The experimental results show that the friction coefficient decreases with increasing velocity; the friction coefficient increases sharply with the rising temperature, the friction coefficient increases at first and then decreases with increasing load for fluted rubber bearings. The numerical results were in good agreement with the experimental results. The numerical results show that complete hydrodynamic lubrication can be formed in the new designed rubber bearing with two cavities. The experimental and numerical results all indicate that there is an appropriate bearing clearance which the friction coefficient is minimum and the load capacity is maximum.

Originality/value
– A new bearing bush structure with two cavities which is beneficial to constructing continuous hydrodynamic lubrication film was designed. A new apparatus for studying the tribological behaviors of the two types of water-lubricated rubber bearings has been devised and established. Experimental and numerical study on the new structure rubber bearing were conducted in the paper.
Study on the tribological properties of titanium alloys sliding against WC-Co during the dry friction
Authors: Niu Qiulin , Zheng Xiaohu , Chen Ming , Ming Weiwei 
Published: March 2014

Purpose
– Titanium alloy has the excellent performance and been widely utilized in aeroengine and airframe manufacture. However, improving the understanding of all aspects of titanium alloy is necessary. The purpose of this paper is to investigate the tribological properties of two typical titanium alloys against tungsten carbide under dry friction.

Design/methodology/approach
– Reciprocating ball-disc friction tests were carried out at room temperature in different loading without lubricant to investigate the friction properties of TA19/WC-Co and TC18/WC-Co friction pairs. The influence of the load on the friction coefficient and friction force was analyzed. The worn surfaces of TA19 and TC18 specimens were observed by the digital microscopy and scanning electron microscopy (SEM). And the wear mechanism was discussed.

Findings
– The results show that the friction coefficients decreased with the increase in the normal load. However, the reduction in the friction coefficient for the TC18 alloy was less than that for the TA19 alloy. The dynamic friction forces with time were not quite coincident with the variation trend of the friction coefficients during the sliding friction. The results observed by the SEM and EDS revealed that several grooving were the main type of frictional wear causing the surfaces of the TA19 and TC18 alloys.

Originality/value
– It is shown in the paper that the tribological property of TA19 alloy was better than that of TC18 when sliding against tungsten carbide under the dry friction conditions. The main types of damage to the TA19/WC-Co friction pair were the ploughing, the delamination fatigue associate with abrasive wear and some diffusive wear. The ploughing and abrasion were the main wear mechanisms for the surface of TC18 alloy.
Learning in plural cultural context
Authors: Raza Ahmad , Sohaib Murad Hasan 
Published: March 2014

Purpose
– This paper aims to reconstruct the metaphor of classroom learning in plural cultural context. It underscores the essential complexity of the human learning and argues for multiple pedagogical practices as a tool for instructional engagement.

Design/methodology/approach
– Technological innovations have given new meanings and interpretations to the social vocabulary of learning across the world. These innovations have created cultural contexts in which metaphor of classroom learning needs to be revisited and reassessed. It discusses the concept of classroom learning in a humanistic cultural context and explores a methodological framework for multiple pedagogic practices a tool for learning engagement based on critique of divergent themes in pedagogical literature.

Findings
– It is argued that classroom learning is a complex microcosm of human bodies, minds and cultures, necessitating major adaptations, both from teachers and learners. It is a continuous engagement, borne out of mutual willingness of teachers and learners to become indivisible part of whole living experience of learning. Classroom as a metaphor of learning would continue to inspire the serious learners, have responded to technological innovations, currently experienced by the human societies across the world, and has gone on to become a “cyber-classroom” in the era of globalization.

Originality/value
– The paper highlights underlying cultural complexities of human learning and hence underscores the need for a revised and pluralistic curriculum for the global management education and those who are engaged in it.
Technological innovation in twenty-first century multicultural teacher preparation
Authors: Blythe Liu Laura , L. Baker Lottie , B. Milman Natalie 
Published: March 2014

Purpose
– An increasingly diverse student population coupled with rapid technological change makes it paramount to examine how technology is being employed in multicultural teacher preparation (MTP) to prepare US teachers to develop the knowledge, skills, and dispositions to foster globally minded, twenty-first century world citizens. The paper aims to discuss these issues.

Design/methodology/approach
– This review employs constant comparative method of analysis to examine empirical research on MTP practices employing technology to prepare teachers for the diverse student populations of twenty-first century classrooms. Although prior reviews have synthesized research findings on MTP, no systematic investigation has examined the role of technology in preparing teachers to support diverse learners. This review of research conducted from 2002 to 2012 explores how technology has been utilized in MTP to enhance face-to-face, online, and blended teacher preparation experiences.

Findings
– Collectively, research reviewed illustrates the power of harnessing technological innovation in preparing TCs as multicultural educators increasingly equipped with globally informed conceptions of diversity and pedagogical approaches for responding to twenty-first century equity issues – and to support their P-12 students in achieving similar goals. While the types and purposes of technology use in MTP varied across these studies, a trend was found in employing technology to contribute to equitable teaching and learning across international settings. In addition, analyses show study contexts varying from teacher preparation classrooms, to field placement settings, to faculty development workshops, both in the USA and abroad.

Originality/value
– This review encourages schools of education to redefine traditional teacher preparation methods and venture into the technology-shaped worlds of twenty-first-century students and their teachers.
Jointly estimating jump betas
Authors: Polimenis Vassilis , Papantonis Ioannis 
Published: March 2014

Purpose
– This paper aims to enhance a co-skew-based risk measurement methodology initially introduced in Polimenis, by extending it for the joint estimation of the jump betas for two stocks.

Design/methodology/approach
– The authors introduce the possibility of idiosyncratic jumps and analyze the robustness of the estimated sensitivities when two stocks are jointly fit to the same set of latent jump factors. When individual stock skews substantially differ from those of the market, the requirement that the individual skew is exactly matched is placing a strain on the single stock estimation system.

Findings
– The authors argue that, once the authors relax this restrictive requirement in an enhanced joint framework, the system calibrates to a more robust solution in terms of uncovering the true magnitude of the latent parameters of the model, at the same time revealing information about the level of idiosyncratic skews in individual stock return distributions.

Research limitations/implications
– Allowing for idiosyncratic skews relaxes the demands placed on the estimation system and hence improves its explanatory power by focusing on matching systematic skew that is more informational. Furthermore, allowing for stock-specific jumps that are not related to the market is a realistic assumption. There is now evidence that idiosyncratic risks are priced as well, and this has been a major drawback and criticism in using CAPM to assess risk premia.

Practical implications
– Since jumps in stock prices incorporate the most valuable information, then quantifying a stock's exposure to jump events can have important practical implications for financial risk management, portfolio construction and option pricing.

Originality/value
– This approach boosts the “signal-to-noise” ratio by utilizing co-skew moments, so that the diffusive component is filtered out through higher-order cumulants. Without making any distributional assumptions, the authors are able not only to capture the asymmetric sensitivity of a stock to latent upward and downward systematic jump risks, but also to uncover the magnitude of idiosyncratic stock skewness. Since cumulants in a Levy process evolve linearly in time, this approach is horizon independent and hence can be deployed at all frequencies.
Impacts of the US macroeconomic news on Asian stock markets
Authors: Nguyen Tho , Ngo Chau 
Published: March 2014

Purpose
– This paper aims to investigate the spillover effect of 14 US key macroeconomic news on the first two moments of 12 Asian stock market returns.

Design/methodology/approach
– The authors collect market expectation and actual scheduled announcements data for 14 key US's macroeconomic announcements from January 2002 to April 2012 from Bloomberg. The dataset consists of six groups: monetary policy and general macroeconomic indicators: the Federal Reserve's target interest rates (FOMC), gross domestic product (GDP), and leading indicator (LI); price indicators: consumer price index (CPI) and producer price index (PPI); business indicator: housing starts (HS) and industrial production (IP); consumption indicators: retail sales (RS) and consumer confidence level (CONSUM); labor market indicators: non-farm payroll (NFP), unemployment level (UE), and jobless claim (JOB); and external sector indicators: current account (CA) and trade balance (TB). The authors also collect daily opening and closing data of 12 Asian stock markets. Following Dow Jones classification, the authors divide them into two groups: five developed markets (Japan, Hong Kong, Republic of Korea, Singapore and Taiwan), and seven emerging markets (China, India, Indonesia, Malaysia, Pakistan, Sri Lanka, and Thailand). The MA-EGARCH (1,1) model is used for the empirical test.

Findings
– First, the authors find that stronger than expected news from the USA is associated with higher conditional mean and lower conditional variance of the Asian stock market returns, in general. Second, the Asian stock markets tend to put more weight on information relating to the US labor market than the other news as this indicator reveals much information about the underlying health of the US economy since full employment is the most important mandate for the US administration and policy makers. Third, in responding to the US news, the Asian emerging markets seem to respond stronger to the US news than the Asian developed markets both in terms of the number of responses and the magnitude of the reaction. This suggests that this could be seen as evidence that emerging markets are more dependent on the information content of the US news than the developed markets. Fourth, the US news is absorbed gradually leading to persisting volatility responses in the Asian stock markets.

Originality/value
– The authors fill a gap in the extant literature in investigating the speeds of the news absorption across the Asia region by examining the spillover effects across three time horizons, namely daily, overnight and intraday.
Temporary and regular workers fulfill their tasks side-by-side, but in different learning conditions
Authors: Augustsson Gunnar 
Published: March 2014

Purpose
– The purpose of this study is to identify temporary workers' (temps') expected conditions for learning when they are leased to a client company (CC) for numerical flexibility.

Design/methodology/approach
– The analysis is based on a phenomenological approach containing 121 transcribed interviews with employees and managers who were active in more than 10 CCs' in seven industries and from seven temporary work agencies.

Findings
– One important finding is that the CC expects temps not to learn something about the surrounding organization, but to limit themselves only to the concrete tasks assigned to them. Another is that temps' opportunities to influence organizational conditions in the CCs seem to be cut off in a strategic way.

Research limitations/implications
– Results are valid for interviewees' expressed thoughts and expectations about temps' workplace learning, not about an actual separation between knowledge and actions in the working conditions.

Practical implications
– CCs associate temps with learning backgrounds that allow them to perform subordinate tasks, such as routine, instructional, or regulatory duties. They associate regular staff with more advanced learning backgrounds and tasks more directly related to occupation and workplace. CCs could benefit from accepting the exchange of knowledge and competence between temps and the company, rather than neglecting it.

Originality/value
– The originality of this paper lies in its contribution to the relatively unexplored topic of workplace learning and leaders and employees' expectations of temps.
Intentions to use and recommend to others
Authors: Maria Correia Loureiro Sandra , Rüdiger Kaufmann Hans , Rabino Samuel 
Published: March 2014

Purpose– In an online banking context this study seeks to explore the relation between the relationship marketing factors of customer intentions to continue to use services and to recommend these services to others, and the technology acceptance factors of self-control, usefulness, customer value, technology-based service encounter satisfaction and reputation. Innovatively this study also compares the proposed model in two countries, Portugal and Austria.Design/methodology/approach– Derived from a review of previous literature, a survey was developed and data were collected using the online survey service of universities in two countries, Portugal and Austria. The partial least squares approach was employed to test the hypotheses.Findings– The findings showed that self-control and usefulness are important antecedents of customer value delivery. Furthermore perceptions of online bank reputation were enhanced by the satisfaction derived from positive customer encounters with online banking services. Unlike the Portuguese, Austrians' perceptions of bank reputation did not significantly influence their intention to continue to use or their propensity to recommend online banking to others.Originality/value– Based on literature which suggests that constructs such as customer value, trust, satisfaction and reputation are inter-related to the technology acceptance model, this paper extends earlier theoretical frameworks and is the first study to incorporate relationship marketing constructs into a model examining intention to use, and recommending online banking services. The study also differentiates the model in two countries that represent different business and cultural settings: Portugal and Austria.
