Authors: Sahin Mumin , Çetinarslan Cem , Misirili Cenk 
Published: August 2013

PurposeBarreling contour variations on the free surfaces of cylindrical upset specimen are to handle measuring for different upsetting reductions and different lubrication conditions in this study. The purpose of this paper is to address this issue.Design/methodology/approachThe materials flow for various materials using different lubricants in upsetting was investigated in this study. SAE 1020 steel, commercially pure copper and CuZn40Pb2 brass were used as the test materials. Upsetting process was applied to the cylindrical specimens using flat end dies. Three types of lubricants, namely grease, graphite and SAE 40 oil, were used in this study. Experiments were performed using a hydraulic press, which has 5 mm/s ram speed, and with a capacity of 150 metric tons.FindingsVariations of barrel radius change clearly with increasing deformation ratio depending on lubricant type. Radius values are different to each other for SAE 1020, Cu and brass specimens. It was understood that surface roughness effect is negligible at material types. The highest radius values were obtained for the brass among all the materials for the same deformation ratio. The materials flow is hard for brass specimens because of its brittleness which is due to cold drawing so its barrel radii are high. On the contrary, SAE 1020 and copper are more suitable for the plastic deformation. As shown in the Figures, the higher radius values were obtained especially with grease lubricant for brass specimens.Research limitations/implicationsIt would be interesting to search material flow for different materials and lubricants. It could be a good idea for future work could be concentrated material flow on upsetting using different lubricants.Practical limitationsThe friction at the faces of contact retards the plastic flow of metals and the surfaces and in its vicinity. A conical wedge of a relatively undeformed metal is formed immediately below it, while the rest of the cylinder metal suffers high strain hardening and bulges out in the form of a barrel. This demonstrates that the metal flows most easily towards the nearest free surface which is the point of least resistance. However, the use of lubricants reduces the degree of bulging and under the conditions of ideal lubrication, the bulging can be brought down to zero.Originality/valueThe main value of this paper is to contribute and fulfil the detailed the dependency of barrel radius on material type by upsetting of specimen of various materials using different lubricants that are being studied so far in the literature.

Published: August 2013

PurposeThe purpose of this paper is surface roughness prediction using pattern recognition for the aluminium hybrid metal matrix composite (HMMC).Design/methodology/approachHybrid composites were manufactured using liquid metallurgy technique. The cast HMMC was machined using an industrial CNC turning centre and the machining vibration signals were acquired using an accelerometer. The acquired signals were processed and used to build a machine learning model for predicting surface finish based on the tool signature.FindingsThe authors established a technique for predicting and monitoring the surface quality during machining using a low cost accelerometer. It is capable of being integrated with the machine controller for online warning of deviations in surface roughness. The system is reconfigurable for any machining condition with a very short training period. The use of this model facilitates online surface roughness monitoring, avoiding the need for costly measuring equipment.Originality/valueThe model developed is innovative and not reported widely to the best of the authors' knowledge. The use of accelerometer‐based surface roughness prediction and control is an innovative approach for automation of machining process monitoring. These can be integrated into any existing machining centre as a standalone system or can be integrated into the CNC controller like Fanuc or Siemens.

PurposeThis paper aims to analyze the friction heat conduction and entransy of two friction linings in the high‐speed slide accident of a mine friction hoist.Design/methodology/approachFirstly, the dynamic thermophysical properties were analyzed and their fitting equations were also obtained. Additionally, the dynamic heat partition ratio was obtained according to the dynamic thermophysical properties. Then, a simple method was developed to solve the temperature rise of friction lining. Finally, based on the theoretical model of temperature rise, the entransy of friction lining with respect to T and t were gained.FindingsThe error of temperature rise between simulation result and experiment result is less than 7 per cent, which proves that the theoretical model is correct. The entransy decreases with the temperature below 40°C and it increases after 40°C. The entransy of lining K is a little higher than that of lining G within 19 s, but the entransy of lining G is much higher than lining K after 19 s and the entransy difference gets great gradually. It is indicated that the lining K has good heat‐resistant property which is of great benefit to the tribological property of friction lining.Practical implicationsThe authors' study provides a fundamental basis for developing a new friction lining with good heat‐resistant property, and it also brings forward a new quantitative method to evaluate the heat‐transfer capability of friction materials.Originality/valueA simple method was introduced to calculate the temperature rise of friction lining with the consideration of dynamic thermophysical properties and dynamic heat partition ratio. And the entransy of friction lining was obtained to evaluate the heat‐transfer capability of friction linings quantitatively.

Published: August 2013

PurposeIn view of the promising growth of e‐payment in Malaysia, this study aims to discover the factors influencing perception towards electronic payment (e‐payment) from the Malaysian consumers’ perspective.Design/methodology/approachLiterature indicates that factors such as benefits, trust, self‐efficacy, ease of use, and security influence consumers’ perception towards e‐payment. A self‐reporting questionnaire was developed and disseminated to 200 respondents, out of which 183 valid responses were considered for further statistical analysis.FindingsThe multiple linear regression results reveal that benefits, self‐efficacy, and ease of use exert significant influences on consumers’ perception towards e‐payment. However, the insignificant results obtained for trust and security warrant further investigation.Research limitations/implicationsThis study proposes five factors for measuring consumers’ perception towards e‐payment which is replicable across different economies. However, the small sample size raises the issue of generalizability which future studies should seek to address.Practical implicationsThe use of e‐payment by the majority of respondents confirms that there is a great potential for future expansion of such payment devices. The challenge is to ensure that it continues to meet consumers’ expectations which will subsequently lead to its increased adoption and use.Originality/valueThis study has advanced knowledge for it has provided information on the current state of e‐payment acceptance and use, particularly among Malaysians. The significant factors identified are beneficial to the policy maker, banking institutions, online transaction facilities providers, and software developers as they develop strategies directed at increasing e‐payment acceptance and use.
The effects of knowledge management capabilities and partnership attributes on the stage‐based e‐business diffusion
Authors: Lin Hsiu‐Fen 
Published: August 2013

PurposeThis study aims to develop a research model to examine the antecedents of three stages of electronic business (e‐business) diffusion (including e‐business initiation, implementation and assimilation). The research model features knowledge management (KM) capabilities (knowledge acquisition, knowledge storage, knowledge dissemination, and knowledge protection), and partnership attributes (partner interdependence, partner trust, and partner commitment) as prominent antecedents of stage‐based e‐business diffusion.Design/methodology/approachData gathered from 398 firms were employed to test the relationships between the research model constructs using a structural equation modeling (SEM) approach.FindingsThe results reveal that the factors for KM capabilities and partnership attributes have different impacts on three stages of e‐business diffusion. In particular, knowledge dissemination has a positive effect on all three e‐business diffusion stages, demonstrating its importance in the decision to shape e‐business diffusion. Moreover, the findings show that three partnership attributes are important enablers during the whole e‐business diffusion process.Practical implicationsIn the context of e‐business, knowledge dissemination activities occur not only within firms, but also between firms and their business partners. Knowledge dissemination enables employees to develop novel solutions to problems that significantly improve on current practices. Hence, the increasing importance of the field of knowledge dissemination is primarily attributed to promotion of successful e‐business activities and increased level of e‐business implementation.Originality/valueTheoretically, this study aims to provide a research model that is capable of understanding the determinants of the stage‐based e‐business diffusion. From a managerial perspective, the findings of this study provide valuable guidelines to policy‐makers and practitioners in implementing e‐business and accelerating e‐business diffusion.
ICT as a catalyst for service business orientation
Authors: Kowalkowski Christian , Kindström Daniel , Gebauer Heiko 
Published: August 2013

PurposeInformation and communication technology (ICT) is a key enabler for new product‐ and process‐oriented services. The purpose of this paper is to investigate how ICT can enable service differentiation and, in doing so, act as a catalyst for a service business orientation.Design/methodology/approachThe paper is based on a qualitative, multi‐case research design with eight multinational goods manufacturers.FindingsThe paper identifies two distinct types of service‐oriented differentiation: services in support of the product (SSP) and services in support of the client's actions (SSC). The study finds that SSC have the largest positive impact on firms' service business orientation.Research limitations/implicationsWestern firms in a limited sample of industries are studied. Furthermore, the service business orientation construct does not include any measurements of service profitability or impact on overall competitive advantage.Practical implicationsTo various extents, successful firms are likely to pursue both SSP and SSC differentiation traits through ICT. The two options are interdependent and the framework presented helps managers to understand both key specificities and their interrelatedness.Originality/valueThe study contributes to theory on service strategies by specifically focusing on the enabling role of ICT for new services and its effects on each of the three dimensions of the service business orientation construct.

Published: August 2013

PurposeThe purpose of this paper is to study the impact that systematization of sales activities through sales process management has, at the firm level, on profitable sales growth in business‐to‐business (B2B) companies. The research aims to compare companies focusing on service offerings to those focusing on product offerings.Design/methodology/approachThe study is based on survey data.FindingsDespite the emergence of service‐dominant logic, B2B service and product companies still differ in how sales process management contributes to firm performance.Research limitations/implicationsThe findings suggest that differences between service and product firms in their sales process management stem from the different underlying modes of interaction. The findings are generalizable to B2B companies.Practical implicationsThe findings help businesses differentiate between productive sales process management practices in product and service firms.Originality/valueThe study contributes to the wider need of operationalizing ideas about sales process management at the level of organizations and business units.
Knowledge translation in healthcare
Authors: Oborn Eivor , Barrett Michael , Racko Girts 
Published: August 2013

PurposeThe authors draw selectively on theories of learning and knowledge, which currently have received little attention from knowledge translation (KT) researchers, and suggest how they might usefully inform future development of the KT literature. The purpose of this paper is to provide conceptual tools and strategies for the growing number of managers, clinicians and decision makers navigating this arena.Design/methodology/approachThe authors conducted a narrative review to synthesise two streams of literature and examine evolving conceptual landscape concerning knowledge translation over the previous three decades. Conceptual mapping was used iteratively to develop and synthesise the literature. Iterative feedback from relevant research and practice stakeholder groups was used to focus and strengthen the review.FindingsKT has been conceptualised along three competing frames; one focusing on linear (largely unidirectional) transfer of knowledge; one focusing on KT as a social process; and another that seeks to more fully incorporate contextual issues in understanding research implementation. Three overlapping themes are found in the management literature that inform these debates in the health literature, namely knowledge boundaries, organisational learning and absorptive capacity. Literature on knowledge boundaries problematizes the nature of boundaries and the stickiness of knowledge. Organisational learning conceptualises the need for organisational wide systems to facilitate learning processes; it also draws on a more expansive view of knowledge. Absorptive capacity focuses at the firm level on the role of developing organisational capabilities that enable the identification, assimilation and use of new knowledge to enable innovation.Research limitations/implicationsThe paper highlights the need to consider KT processes at multiple levels, including individual, organisational and strategic levels. These are important not only for research but also have practical implications for individuals and organisations involved in KT processes.Originality/valueThis review summarises and integrates two largely separate literature streams on knowledge translation – namely health services research and management scholarship. In addition to outlining and organising the conceptual landscape around knowledge transfer, the paper contributes by highlighting how management literature on knowledge and learning theories might inform health services research on knowledge translation.
Engaging physicians in organisational improvement work
Authors: Bååthe Fredrik , Erik Norbäck Lars 
Published: August 2013

PurposeTo improve health‐care delivery from within, managers need to engage physicians in organisational development work. Physicians and managers have different mindsets/professional identities which hinder effective communication. The aim of this paper is to explore how managers can transform this situation.Design/methodology/approachThe authors' interview study reveals physicians' own perspective on engagement for organisational improvement. They discuss identities from three theoretical perspectives and explore the mindsets of physicians and managers. They also explore the need to modify professional identities and how this can be achieved.FindingsIf managers want physicians to engage in improvements, they must learn to understand and appreciate physician identity. This might challenge managers' identity. The paper shows how managers – primarily in a Swedish context – could act to facilitate physician engagement. This in turn might challenge physician identity.Research limitations/implicationsStudies from the western world show a coherent picture of professional identities, despite structural differences in national health‐care systems. The paper argues, therefore, that the results can be relevant to many other health‐care systems and settings.Originality/valueThe paper provides an alternative to the prevailing managerial control perspective. The alternative is simple, yet complex and challenging, and as the authors understand it, necessary for health care to evolve, from within.

Published: August 2013

PurposeDeveloping a performance measure and reporting the results to support decision making at an individual level has yielded poor results in many health systems. The purpose of this paper is to highlight the factors associated with the dissemination of performance information that generate and support continuous improvement in health organizations.Design/methodology/approachA systematic data collection strategy that includes empirical and theoretical research published from 1980 to 2010, both qualitative and quantitative, was performed on Web of Science, Current Contents, EMBASE and MEDLINE. A narrative synthesis method was used to iteratively detail explicative processes that underlie the intervention. A classification and synthesis framework was developed, drawing on knowledge transfer and exchange (KTE) literature. The sample consisted of 114 articles, including seven systematic or exhaustive reviews.FindingsResults showed that dissemination in itself is not enough to produce improvement initiatives. Successful dissemination depends on various factors, which influence the way collective actors react to performance information such as the clarity of objectives, the relationships between stakeholders, the system's governance and the available incentives.Research limitations/implicationsThis review was limited to the process of knowledge dissemination in health systems and its utilization by users at the health organization level. Issues related to improvement initiatives deserve more attention.Practical implicationsKnowledge dissemination goes beyond better communication and should be considered as carefully as the measurement of performance. Choices pertaining to intervention should be continuously prompted by the concern to support organizational action.Originality/valueWhile considerable attention was paid to the public reporting of performance information, this review sheds some light on a more promising avenue for changes and improvements, notably in public health systems.
Ascribing emotion to reasonable use in accelerated cancer services
Authors: Roelsgaard Obling Anne 
Published: August 2013

PurposeA recurrent theme in medical sociology has been the juxtaposition of emotion with scientific rationality in the delivery of health care services. However, apart from addressing this juxtaposition very little is said about the complex intertwinement of “emotional” and “rational” practices which makes up professionals' own day‐to‐day work experiences – and how these experiences are influenced by present ways of organising health care. This paper aims to explore the ways that hospital doctors relate emotions to their understanding of professional medical work and how they respond to recent organisational changes within the field.Design/methodology/approachDrawing upon a small series of semi‐structured interviews (n=14) with doctors from a public teaching hospital in Denmark, the paper adopts a constructivist framework to analyse personal biographies of health professionals' working lives.FindingsThe doctors represented rich accounts of professional medical work, which includes an understanding of what a doctor should feel and how he/she should make him/herself emotionally available to others. However, the impetus for making this appearance was not left unaffected by recent new public management reforms and attempts to accelerate the delivery of services.Practical implicationsThe organisation of cancer services into a work system, which consists of a set of tasks broken down into narrow jobs, underestimates the emotional components of patient‐doctor encounters. This makes the creation and maintenance of a genuine patient‐doctor relationship difficult and the result is feelings of a failed encounter on behalf of the doctor.Originality/valueThe paper suggests that recent rearrangements of cancer services complicate doctors' ability to incorporate emotion into a stream of medical care in a “rational” way. This is shown to challenge their professional ethos and the forms emotional engagement takes in medical practice.

Authors: Ogbenege Janet , Adetimirin Airen 
Published: August 2013

PurposeSoftware has played a crucial role in the management of library operations. Nigerian university libraries are embarking on automation by adopting different library software but many fail due to the wrong selection of software and improper management of the automation project. The paper aims to examine the selection and use of KOHA software in two private Nigerian universities.Design/methodology/approachPurposive sampling was used to select 255 respondents made up of two systems librarians, eight heads of library units and 245 faculty. Data were collected through questionnaire, interview and observation.FindingsKOHA was selected because of integration, ease of use, accessibility, flexibility and feasibility study was carried out. The software was not maximally used in both universities (RU: 49 percent, BU: 64.3 percent).Originality/valueThis paper investigates the factors used for selection of the software, level of use and challenges to its use. It is relevant to university libraries because it emphasises the need to carry out in‐depth feasibility study before the adoption of software to increase the effectiveness of their libraries.
