Authors: Grønholdt Lars , Martensen Anne , Jørgensen Stig , Jensen Peter 
Published: March 2015

Purpose
– The purpose of this paper is to examine how essential dimensions of customer experience management (CEM) drive business performance in Danish companies.

Design/methodology/approach
– An empirical study is conducted to investigate the relationships between seven CEM dimensions, differentiation, market performance and financial performance. The conceptual model is operationalized by a structural equation model, and the model is estimated and tested by using the partial least squares method. A survey among 484 companies in Denmark forms the empirical basis for the study.

Findings
– The findings provide evidence that the seven CEM dimensions influence differentiation, market performance and financial performance. High-performing companies differ significantly from low-performing companies with regard to how they master the CEM, meaning that those companies which incorporate superior customer experience into their products and service enjoy measurable financial success.

Research limitations/implications
– This study is limited to the seven identified CEM dimensions in Danish companies.

Practical implications
– This study has clear implications in terms of identifying and measuring the importance of essential CEM dimensions which influence business performance. The results can help companies to understand CEM and develop CEM strategies.

Originality/value
– The paper provides a deeper insight into CEM and how CEM works.
Agencies, it’s time to innovate!
Authors: Palm Klas , Lilja Johan , Wiklund Håkan 
Published: March 2015

Purpose
– The purpose of this paper is to explore the phenomenon of innovation in the current Swedish governmental administration system. More specifically, the paper explores the current understanding within the system of what innovation is, as well as why and how it should be achieved. Innovation is currently at the top of many agendas worldwide: not only in the private sector but also when it comes to increasing quality, efficiency and effectiveness in public administration. In Sweden, this is reflected in the recent call from the Government for innovation in public management. However, innovation has not traditionally occurred to any significant extent on the strategic level of Swedish public management. Furthermore, governmental administration is a complex system in need of coordination and alignment for this new call to be effectively realized in practice.

Design/methodology/approach
– This paper has been based on a qualitative approach with a case consisting of three embedded units: the Government itself, a ministry and a Government agency. The data have been collected from documents and interviews.

Findings
– This paper shows that there is currently a notable disparity when it comes to how aspects of innovation are understood at different levels within the Swedish governmental administration system. Furthermore, the recent business development to increase the standardization of work processes is perceived as having created poorer preconditions for working with innovations.

Practical implications
– The results highlight critical areas of disparity and possibilities for improvement toward a shared understanding and aligned innovation actions within the system.

Originality/value
– This paper contributes knowledge about the current understanding of innovation in the Swedish governmental administration system.
Torsional tribological behavior of polytetrafluoroethylene composites filled with hexagonal boron nitride and phenyl p-hydroxybenzoate under different angular displacements
Authors: Wang Shibo , Cao Bo , Teng Bing 
Published: March 2015

Purpose
– The purpose of this paper is to investigate the effect of hexagonal boron nitride (h-BN) and poly (phenyl p-hydroxybenzoate) (PHBA) on improving the torsional tribological behavior of polytetrafluoroethylene (PTFE).

Design/methodology/approach
– This paper investigates the torsional tribological behavior of PTFE composites filled with h-BN and PHBA under different angular displacements with a plane-on-plane torsional friction tester. The worn surface of PTFE composites was investigated by using a scanning electron microscope.

Findings
– The shape of T–Θ curves of PTFE composites was influenced by both content fillers and torsional angule. The material with a higher coefficient of sliding friction exhibited the larger torsional angle under which the torsional regime transited from a partial slip to a gross slip. PTFE composites filled with 20 weight per cent PHBA and 10 weight per cent h-BN showed the best anti-wear properties. The specific wear rate of composites exhibits a negative correlation with material hardness. The wear volume loss presents a positive correlation with friction dissipation energy. The specific wear rate of all composites decreased with increasing torsional angle. The dominant wear mechanism of pure PTFE was adhesive wear. The slight plastic flow and plowing occurred on the worn surfaces of PTFE composites because of the higher hardness of composites and the lubrication of h-BN particles with layer crystal structure.

Originality/value
– This paper put forward a kind of PTFE composite with low torsional wear rate, which can be used in the sliding slewing bearing or the center plate of a bogie.
Investigations on the effect of oil quality on gearboxes using neural network predictors
Authors: Kalkat Menderes 
Published: March 2015

Purpose– The purpose of this paper was to perform an experimental investigation to analyze vibration and noise of unloaded gearbox with different oil quality. All motor-driven machinery used in the modern world can develop faults. The maintenance plans include analyzing the external relevant information of critical components, in order to evaluate its internal state. From the beginning of the twentieth century, different technologies have been used to process signals of dynamical systems.Design/methodology/approach– A proposed neural network (NN) is also employed to predict vibration parameters of the experimental test rig. Moreover, four types of oils are used for gearbox to predict reliable oil. Vibration signals extracted from rotating parts of machineries carry lot many information within them about the condition of the operating machine. Further processing of these raw vibration signatures measured at a convenient location of the machine unravels the condition of the component or the assembly under study. The experimental stand for testing an unloaded gearbox is composed by actuated direct current (DC) driving system.Findings– This paper deals with the effectiveness of wavelet-based features for fault diagnosis of a gearbox using two types of artificial neural networks (ANNs) and stress analyzed with computer-based software ANNs. The results improved that the proposed NN has superior performance to adapt experimental results.Practical implications– This paper is one such attempt to apply machine learning methods like ANN. This work deals with extraction of wavelet features from the vibration data of a gearbox system and classification of gear faults using ANNs.Originality/value– These kind of NN-based approaches are novel approaches to predict real-time vibration and acceleration parameters of unloaded gearbox with five types of oils. Also, the investigation contains new information about studied process, containing elements of novelty.
Experimental and CFD investigations of carbon/SS316 mechanical face seals under different lubricating conditions
Authors: Kavinprasad S. , Shankar S. , Karthic M. 
Published: March 2015

Purpose
– The purpose of this paper is to test mechanical face seals made of carbon/SS316 with different coolants for evaluating its tribological performance. The reliability of a mechanical seal mainly depends on the seal materials and the type of coolant used for the lubrication.

Design/methodology/approach
– Compressed air, vacuum and nitrogen are the main coolants utilized for the experimental work, and the obtained results are compared with the dry running case for a specified period. The experimental results are also validated with the computational fluid dynamics (CFD) simulation results.

Findings
– The results shows that the sealing pressure, sliding speed and materials used would be the predominant factors for the seal design. Over compressed air, vacuum and nitrogen cooling techniques were found to be more efficient.

Originality/value
– The experimental results are also validated with the CFD simulation results. This paper also emphasizes the usage of vacuum as a cooling medium in industries, which will enhance the seal life at an economical cost over nitrogen.
Wear predictions for cams in line contacts based on multidisciplinary simulation
Authors: Qin Wenjie , Duan Lunjing 
Published: March 2015

Purpose
– This paper aims to present the model and method involving multi-body system dynamic analysis, finite element quasi-statics contact analysis and numerical calculation of elastohydrodynamic lubrication (EHL), according to the cam wear prediction using Archard’s model. Cam–follower kinematic pairs always work under wear because of concentrated contacts. Given that a cam and follower contact often operates in the mixed or boundary lubrication regime, simulation of cam wear is a multidisciplinary problem including kinematic considerations, dynamic load and stress calculations and elastohydrodynamic film thickness evaluations.

Design/methodology/approach
– Multi-body system dynamic analysis, finite element quasi-statics contact analysis and numerical calculation of EHL are applied to obtain the dynamic loads, the time histories of contact pressure and the oil film thicknesses in cam–follower conjunctions to predict cam wear quantitatively.

Findings
– The wear depth of the cam in the valve train of a heavy-load diesel engine is calculated, which is in good agreement with the measured value in the practical test. The results show that the cam–tappet pair operates under a mixed lubrication or boundary lubrication, and the wear depths on both sides of the cam nose are extremely great. The wear of these points can be decreased significantly by modifying the local cam profile to enlarge the radii of curvature.

Originality/value
– The main value of this work lies in the model and method involving multi-body system dynamic analysis, finite element quasi-statics contact analysis and numerical calculation of EHL, which can give good prediction for the wear of cam.
Temperature rise characteristic of MR fluid in a multi-disc MR clutch under slip condition
Authors: Wang Daoming , Hou Youfu , Tian Zuzhi , Meng Qingrui 
Published: March 2015

Purpose
– This study aims to reveal the temperature rise characteristic of magnetorheological (MR) fluid in a multi-disc MR clutch under slip condition, including the temperature distribution regularity and the impact factors.

Design/methodology/approach
– Three-dimensional transient heat conduction equation for the MR fluid in the working gap was derived based on the heat transfer theory. Then, numerical simulation was conducted to analyze the temperature field of MR fluid. Furthermore, an experimental study was performed to explore the temperature distribution of the MR fluid in radial and circumferential directions, as well as the effects of disc groove, slip power and gap size on temperature rise characteristic of the MR fluid.

Findings
– The results show that temperature appears to be largest in the center of the working gap and the temperature difference increases with the slip time. However, the temperature field in a circumferential direction is basically the same, but it presents slightly lower in the groove area. The temperature of the MR fluid increases linearly with the slip time and the rise rate increases with the slip power. Moreover, the temperature rise value decreases with the increase of gap size.

Originality/value
– In this paper, the temperature gradients, both in radial and circumferential directions, are experimentally measured going beyond the estimation by computer simulations. In addition, the factors that influence the temperature rise characteristic of MR fluid were fully analyzed. The results could provide a reliable basis for the development of cooling technology for high-power MR devices.
HVOF Diamalloy 2002 coating of steel surface: electrochemical corrosion resistance
Authors: Yilbas B. S. , Toor I.-H. , Patel F. , Al-Shehri Y. , Baig M. A. 
Published: March 2015

Purpose
– The purpose of this paper is to investigate the corrosion resistance of high velocity oxy-fuel (HVOF)-sprayed Diamalloy 2002 coating on carbon steel. The coating microstructure is examined in line with the corrosion resistance.

Design/methodology/approach
– HVOF spraying of coating is achieved, and the coating response to electrolytic solution is measured experimentally in terms of corrosion resistance.

Findings
– HVOF coating improves the corrosion resistance of the substrate such that the corrosion rate of the substrate is 7.1 mpy and the coating results in 4.5 mpy. However, presence of deep pit sites at the surface suggests the occurrence of preferential corrosion around the splat boundaries. In addition, closely spaced surface texture peaks act as crevice corrosion centers at the surface while initiating the formation of deep pit sites.

Research limitations/implications
– This study is limited by experimental investigations. In future, it may be extended to include model studies.

Practical implications
– The findings of this study are very useful for those working in the coating industry. However, HVOF coating is limited to high temperature protection in harsh environments.

Social implications
– It is useful for the power industry, particularly for gas turbines.

Originality/value
– It is an original work and describes the corrosion resistance of the coating surface. It is found that the coating improved the corrosion resistance of the steel surface.
Cityscape promotions and the use of place images at the Olympic Games
Authors: Nadeau John , O'Reilly Norman , Heslop Louise A. 
Published: March 2015

Purpose– The purpose of this paper is to investigate the extent that marketers are using place-based images to promote their brands within the host city of the Olympic Games. It is thought that non-sponsors may use place imagery as an alternate way to affiliate with the event or sponsors may use place to enrich their sponsorship activity.Design/methodology/approach– The study uses an observation-based approach to collect a sample of place-based promotional activity that is accessible to pedestrians during the 2012 Olympic Games.Findings– Results reveal that official sponsors and non-official sponsors are both using place-based imagery in their promotions within the host city of the Olympic Games. However, non-sponsors use place images more frequently than sponsors of the event. Place images were invoked by promoters using country flags most frequently followed by icons and explicit mention of place. The leading dimensions of place images employed by marketers include country character, the built environment and people competence. Place-based promotional activity was frequently observed in shopping areas, transportation, sports venues and in free media.Research limitations/implications– Results provide justification for future research in the area. Specifically, the need for empirical work based on surveys of consumers and interviews with practitioners are noted.Practical implications– In an era of highly protected event marketing rights, the existence of promotions based on place images can be a useful application for official sponsors to leverage their investments and protect their exclusivity. Similarly, results are beneficial to non-official sponsors who may seek to market in the vicinity of these events without infringing on the rights of official sponsors.Originality/value– While previous research on place, mega-events, the Olympic Games and sponsors has found the images of the three to be related, it is not known to what extent sponsors and non-sponsors utilize place images in their promotional activities throughout the Olympic host city.
Immersive information behaviour: using the documents of the future
Authors: Robinson Lyn 
Published: March 2015

Purpose– The purpose of this paper is to present the case for studies of information behaviour in the use of immersive documents. Immersive documents, where unreality is perceived as reality, arise from a combination of rapidly developing technologies and applications: pervasive and networked information, multi-sensory interaction and the creation of participatory texts.Design/methodology/approach– A critical and selective analysis of relevant literature is presented.Findings– Immersive documents are likely to have a significant effect on library/information service provision, as it is to expected that novel information behaviours will emerge as these documents become widely used. Studies of immersive information behaviour and practices will be valuable in planning for how library/information services can best provide access to such documents, and may also guide the development of such documents. They may also contribute to the development of information behaviour research generally, and to better interaction between research and practice.Research limitations/implications– As such documents are not yet in wide use, the conclusions are necessarily speculative.Originality/value– This is the first paper to discuss information behaviour in respect of immersive documents.

The concentration of the global alcohol industry and its penetration in the African region
Authors: Jernigan David H. , Babor Thomas F. 
Published: March 2015

AbstractAimsTo describe the penetration and expansion of the global alcohol industry into the African region, as a context for exploring the implications for public health.MethodsSource materials for this study came primarily from market research and the business press. This was supplemented by industry sources (from websites, company annual reports), World Health Organization reports and the scientific literature.ResultsDrinking in Africa is characterized by high rates of abstention and a high prevalence of heavy episodic consumption among those who drink. Much of the region is currently experiencing a rapid rise in consumption. Rising populations and income and the rapid pace of urbanization make Africa very attractive to the global alcohol industry, and industry leaders have identified Africa as a key area for growth. The shift from collaboration to competition in Africa among the global alcohol companies has prompted increasing alcohol production, promotion, new product development, pricing schemes and stakeholder lobbying.ConclusionsBeer consumption has increased across most of the continent, and global brewers view themselves as legitimate players at the alcohol policy table. Weak alcohol policy environments may be compromised further in terms of public health protections by alcohol industry opposition to effective measures such as marketing regulations, availability controls and taxation.
A Novel TAZ Gene Mutation and Mosaicism in a Polish Family with Barth Syndrome
Authors: Zapała Barbara , Płatek Teresa , Wybrańska Iwona 
Published: March 2015

SummaryBarth syndrome (BTHS) is an X‐linked recessive disease primarily affecting males. Clinically, the disease is characterized by hypertrophic or dilated cardiomyopathy, skeletal myopathy, chronic/cyclic neutropenia, 3‐methylglutaconic aciduria, growth retardation and respiratory chain dysfunction. It is caused by mutations in the TAZ gene coding for the tafazzin protein which is responsible for cardiolipin remodeling. In this work, we present a novel pathogenic TAZ mutation c.83T>A, p.Val28Glu, found in mosaic form in almost all female members of a Polish family. Sanger sequencing of DNA from peripheral blood and from epithelial cells showed female mosaicism in three generations. This appears to be a new mechanism of inheritance and further research is required in order to understand the mechanism of this mosaicism. We conclude that BTHS genetic testing should include two or more tissues for women that appear to be noncarriers when blood DNA is initially tested. The results of our study should not only be applicable to BTHS families, but also to families with other X‐linked diseases.

Authors: Kovac Nikola , Grainger Nicholas , Hurworth Mark 
Published: March 2015

AbstractBackgroundThe reduced availability of human cadavers and their associated high costs, coupled with an increasing requirement for meeting continuing professional development targets, has accentuated the need for alternative training models that meet current ethical standards. The aim of this study is to identify suitable substitutes that are accessible and cost effective for use as training models for meniscal repairs and small joint arthroscopy.MethodOvine, bovine and porcine stifles were analysed for comparable anatomy to the human knee, arthroscopic access, arthroscopic view and ease of meniscal repair.ResultsThe bovine stifle joint was found to be too large and offered limited access due to a large anterior fat pad and thick surrounding soft tissue. The ovine and bovine stifles were both easily available and had comparable anatomy to the human knee. Advantages of the porcine stifle include better availability and easier accessibility, comparable anatomy to the human knee and its relatively larger size that made it easier to arthroscope.ConclusionPorcine stifles are cost effective, accessible, allow for meniscal repair and are suitable for arthroscopic access and view. Our view is that they are an ideal training model for arthroscopic meniscal repair, small joint arthroscopy and anterior cruciate ligament reconstruction.
