Authors: Li Pengju , Zhu Yongsheng , Zhang Youyun , Yue Pengfei 
Published: June 2015

Purpose
– This paper aims to present the theoretical and experimental investigation of the temperature of high speed and heavy haul tilting pad journal bearing.

Design/methodology/approach
– The bearing is 152.15 mm in diameter with three slenderness ratios (L/D) and three clearance ratios. The equations that govern the flow and energy transport are solved by the finite difference method, and the experimental tests are conducted in a test rig of high speed and heavy haul tilting pad journal bearing. The shaft speed ranges from 3,000 to 16,500 r/min (the highest linear-velocity equals 131.4 m/s), and the three static loads are 10, 20 and 30 KN.

Findings
– The comparisons between numerical results and experimental results show better correlations. It is shown in the theoretical and experimental results that the temperature increases with static load and shaft speed and decreases with clearance ratio and L/D.

Originality/value
– The theoretical models presented in this paper can be used to predict the temperature of tilting pad journal bearing when the shaft’s linear velocity is up to 130 m/s.

Authors: Buczek Bronislaw , Zajezierska Anna 
Published: June 2015

Purpose
– The aim of this paper was to investigate the possibility of reusing frying oil, obtained during thermal treatment of food in fast-food restaurants for production of plastic greases.

Design/methodology/approach
– In accordance with the proposed research concept, the used frying oil was to be the base oil of biodegradable plastic greases thickened with calcium 12-hydroxystearate and lithium 12-hydroxystearate. These studies included the determination of the effect of variable amounts of used oil component in the base oil on the properties of the resultant plastic greases.

Findings
– It was found that the optimum amount of the component in the base oil is 10-15 per cent. Calcium and lithium greases prepared in such a way possess a quality to that of greases prepared with fresh rapeseed oil.

Research limitations/implications
– Higher concentrations of used frying oil in the base oil adversely affect the degree of thickening, thixotropic properties and dropping point of the grease, as well as, creating technological problems.

Practical implications
– The investigations, beside their research goals have also a practical character – recycling waste material in place of its present method of disposal.

Originality/value
– One of the least expensive material, and most commonly used to produce biodegradable lubricants are vegetable oils. In recent years, besides introducing biodegradable lubricating oils, increasing interest is observed in the use of plastic greases of high biodegradability. Now, it is possible to obtain such greases with additive of used frying oils. Biodegradable greases are used as lubrication of open gear, food production equipment, central lubrication system in cars and railway engineering.
Effect of heat treatment on tribological behavior of zinc aluminum alloy reinforced with graphite and SIC particles for journal bearing
Authors: Kiran TS , Prasannakumar M , Basavarajappa S , Viswanatha BM 
Published: June 2015

Purpose
– The purpose of the paper is to study the dry sliding wear behavior of as-cast and heat-treated zinc-aluminum (ZA-27) alloy, reinforced with silicon carbide and graphite particles.

Design/methodology/approach
– The alloy and composite samples were prepared with stir casting technique. Heat treatment was carried out for samples at a temperature of 370°C followed by quenching in water at room temperature. Subsequently, the heat-treated samples were aged at 180°C and quenched in water at room temperature. The wear tests were carried using pin-on-disc apparatus at room temperature at different applied loads, sliding speed and sliding distance.

Findings
– The wear volume loss of as-cast samples was more compared with heat treated samples. Composites exhibited improved wear resistance than base alloy.

Originality/value
– Hybrid metal matrix composites with heat treatment has exhibited superior wear behavior in dry sliding conditions.
Effects of misalignment on the structure characteristics of bump-type foil bearings: a comparison between experimental and theoretical results
Authors: Feng Kai , Zhao Xueyuan 
Published: June 2015

Purpose
– The purpose of this paper is to investigate the effects of misalignment on the static and dynamics characteristics of bump-type foil bearings (BFBs). High-speed and high-temperature oil-free turbomachinery can be realized with the use of gas foil bearings (GFBs). GFBs have a flexible supporting structure; thus, they can tolerate a higher degree of misalignment compared with rolling element bearings.

Design/methodology/approach
– A test rig for GFBs has been developed to measure the effects of misalignment on the structure characteristics of bump-type foil bearings. The link-spring model, which is the foil structure model presented previously by the authors, is used as a basis in the present study to predict the static and dynamic performances of the foil structure. In general, predictions of the dynamic characteristics exhibit good agreement with the measurements acquired from the dynamic load tests.

Findings
– Results from the static tests show that GFBs develop high stiffness when the misalignment angle increases. Moreover, the dynamic characteristics of GFBs are identified by considering the test bearing supported by a non-rotating shaft as a one-degree-of-freedom system. The results indicate that the dynamic characteristics of GFBs strongly depend on excitation frequency and excitation amplitude because of the variation in the dynamic friction force within the foil structure. The structural stiffness and equivalent viscous damping increase with an increase in the misalignment angle.

Originality/value
– The present study focuses on the misalignment of GFBs and investigates experimentally the effects of misalignment on the structure characteristics of GFBs.

Assessing asset monitoring levels for maintenance operations
Authors: Alabdulkarim Abdullah A , Ball Peter , Tiwari Ashutosh 
Published: June 2015

Purpose
– Asset management has recently gained significance due to emerging business models such as Product Service Systems where the sale of asset use, rather than the sale of the asset itself, is applied. This leaves the responsibility of the maintenance tasks to fall on the shoulders of the manufacturer/supplier to provide high asset availability. The use of asset monitoring assists in providing high availability but the level of monitoring and maintenance needs to be assessed for cost effectiveness. There is a lack of available tools and understanding of their value in assessing monitoring levels. The paper aims to discuss these issues.

Design/methodology/approach
– This research aims to develop a dynamic modelling approach using Discrete Event Simulation (DES) to assess such maintenance systems in order to provide a better understanding of the behaviour of complex maintenance operations. Interviews were conducted and literature was analysed to gather modelling requirements. Generic models were created, followed by simulation models, to examine how maintenance operation systems behave regarding different levels of asset monitoring.

Findings
– This research indicates that DES discerns varying levels of complexity of maintenance operations but that more sophisticated asset monitoring levels will not necessarily result in a higher asset performance. The paper shows that it is possible to assess the impact of monitoring levels as well as make other changes to system operation that may be more or less effective.

Practical implications
– The proposed tool supports the maintenance operations decision makers to select the appropriate asset monitoring level that suits their operational needs.

Originality/value
– A novel DES approach was developed to assess asset monitoring levels for maintenance operations. In applying this quantitative approach, it was demonstrated that higher asset monitoring levels do not necessarily result in higher asset availability. The work provides a means of evaluating the constraints in the system that an asset is part of rather than focusing on the asset in isolation.
Achieving a competitive supply chain network for a manufacturer
Authors: Jin Yan , Edmunds Paulette 
Published: June 2015

Purpose– Collaboration in supply chain networks (SCN) becomes extremely important for manufacturers seeking a sustainable competitive advantage. Such competitiveness depends on the SCN resources a manufacturing firm can allocate, the capabilities to identify and deploy these network resources effectively, and practices and applications the firm arranges for these resources. The purpose of this paper is to develop a conceptual framework that investigates the relationships between these network constructs and their influences on firm performance.Design/methodology/approach– An extensive literature review of supply chain management was conducted to explicate why some manufacturers outperform others. A resource-based view, dynamic capability theory, and extended resource-based view were employed to develop a conceptual model that investigates relationships between the resources, capabilities, and practices of a SCN. The relationships were then examined to analyze their influences on firm performance. Several cases and practical examples were included in the study to give a better understanding of the conceptual research model. Various keywords were used in searching literature for the constructs of the research model. For example, “knowledge” and “supply chain network” were used to search the literature regarding the SCN intangible resources.Findings– This study uses a conceptual model to identify SCN resources that are dispersed in the internal territory among different network members, SCN capabilities that are developed based on these network resources and lead to the firm’s competitive performance, and SCN practices used to acquire network resources and build network capabilities.Research limitations/implications– The conceptual model of SCN resources, capabilities, and practices needs further empirical validation.Practical implications– The conceptual model provides a framework for managers to identify the critical resources, capabilities, and practices of a SCN that help a firm achieve sustainable competitive performance.Originality/value– This research builds a comprehensive picture of relationships between a manufacturing firm’s strategic resources, capabilities, and practices in a SCN. It also provides a theoretical foundation for future research on developing instruments for resources, practices, and capabilities of a SCN and empirically testing the relationships among the appropriate constructs.

Authors: Aboelmaged Mohamed Gamal Shehata 
Published: June 2015

Purpose
– The purpose of this paper is to develop a multifaceted perspective on e-maintenance research and practice over 12 years from 2002 to 2013.

Design/methodology/approach
– A qualitative research approach is conducted through analysing e-maintenance literature published in peer-review journals from 2002 to 2013 in operations management, information systems, computer science and engineering disciplines.

Findings
– A multifaceted perspective that reflects evolutionary, managerial, and technological domains of e-maintenance research has been emerged and explained. In addition, stages of e-maintenance process (i.e. integration, aggregation, and prediction) tend to synchronize with organizational levels (i.e. strategic, tactical, and operational) and stimulate the value of e-maintenance practices across the enterprise. However, there are many managerial and technological challenges that inhibit successful implementation of e-maintenance system.

Practical implications
– The present research offers managers and vendors a frame of reference that facilitates e-maintenance adoption and implementation. In addition, there is a need for theoretical as well as empirical research in the future to validate the multifaceted perspective in the present study and to obtain more insight into the nature of e-maintenance issues in various settings.

Originality/value
– The present paper is one of the first attempts to bridge the gaps in a currently cluttered field of e-maintenance research. It also provides both academics and practitioners with a useful framework that sustains rigorous e-maintenance research and practice.
Performance implications of industry appropriability for manufacturing SMEs
Authors: Batra Safal , Sharma Sunil , Dixit Mukund R , Vohra Neharika , Gupta Vishal K 
Published: June 2015

Purpose– Industry appropriability – the degree to which firms in an industry can appropriate benefits from their innovations – is a crucial dimension of industry environment. Small and medium manufacturing enterprises (manufacturing SMEs), because of their limited resource base, tend to be especially sensitive to the appropriability conditions in their industry. The purpose of this paper is to understand the influence of industry appropriability on firm outcomes (innovativeness and performance), and posits technology orientation as a dynamic capability that helps firms overcome appropriability barriers in their industry.Design/methodology/approach– Data were collected from 162 manufacturing SMEs in India. Multiple linear regression analysis was used to test the proposed hypotheses.Findings– This study reveals that the perceived level of appropriability of manufacturing SMEs impacts their innovativeness. Further, findings also support technology orientation as a crucial firm-specific characteristic which enables firms to overcome unfavorable appropriability conditions. Technology orientation plays a significant role in mitigating the negative impact of lower appropriability conditions. Even when the patent regime is unfavorable, technology-oriented firms are able to innovate and perform better.Practical implications– The findings suggest technology orientation as a strategic mechanism for manufacturing SMEs to respond to conditions of unfavorable appropriability regime.Originality/value– This study elaborates the benefits of integrating industry-level and firm-level characteristics. Specifically, an attempt was made to extend the existing research on industry appropriability by bringing in the contingent effect of technology orientation. The context of manufacturing SMEs yielded several interesting insights.
Strategy implementation and organizational levels: resourcing for innovation as a case
Authors: Engberg Robert , Hörte Sven-Åke , Lundbäck Magnus 
Published: June 2015

Purpose– The purpose of this paper is to further the understanding of the link between human capital and strategy across hierarchies.Design/methodology/approach– Using data on personality traits as a proxy for strategy implementation success, empirical data included 1,738 Operational Personality Questionnaire personality traits assessments in one large multinational firm. Respondents spanned from top-management to white-collar employees. Besides personality traits, measures include employment level and employment status. In addition, a total of 43 interviews were performed on the employee-level, with middle managers, with senior managers, and with executive-level managers.Findings– After a strategic shift, successful implementation of a human resource management (HRM) strategy decreased down through the hierachies. This has implications for a firm trying to realign its resources to a new strategy. If the strategic shift is large, this will pose a great problem as human capital further down in the hierarchy will not be aligned to the new strategy, but rather be aligned to the old strategy.Research limitations/implications– The findings are discussed using the concept of the strategic centre of gravity. The authors elaborate on the concept in terms of the origin, mass, and inertia of the strategic centre of gravity.Practical implications– A successful strategic shift in this sense will to a great extent depend on how successful the implementation is at lower levels of hierarchy, thus pointing to the importance to considering this when designing and pursuing strategic change.Originality/value– The research contributes to the HRM literature by furthering the understanding of aligning human capital on different organizational levels to strategy and by developing the concept of the strategic centre of gravity.
Part time work, productivity and institutional policies
Authors: Ierodiakonou Christiana , Stavrou Eleni 
Published: June 2015

Purpose– The purpose of this paper is to develop and empirically test a multilevel framework for examining the links between part time work, productivity and institutional context. The authors emphasize the importance of integrating different theoretical perspectives to enrich the understanding of nonstandard work arrangements such as part time and organizational effectiveness such as productivity.Design/methodology/approach– The authors used data from 2,839 businesses in 21 OECD countries. At the firm level, primary data were collected from the 2008 to 2010 survey of the Cranet research network. At the national level, the authors used information from OECD and Boteroet al.(2004). The authors analysed the data using hierarchical linear modelling.Findings– Firm use of part time work relates negatively to employment legislation but positively to gender empowerment. The relationship between part time work and productivity at firm level is moderated by employment legislation.Research limitations/implications– This study provides a basis for research in nonstandard work, firm outcomes and institutional policies to further advance.Practical implications– Results indicate how managers should consider the relevant institutional context when deciding whether to promote the use of part time work. Results also show that policy-makers should be careful since employment policies may have adverse effects on use of part time in specific contexts.Originality/value– The authors make theoretical and empirical contributions to the study of nonstandard arrangements by introducing a framework that better captures the complex interrelations between use of part time work, productivity and institutional context. Theoretically, the authors combine the resource based view with institutional theory into a multilevel framework that challenges the conventional model of the flexible firm.
A RDF-based approach to metadata crosswalk for semantic interoperability at the data element level
Authors: Chen Ya-Ning 
Published: June 2015

Purpose
– The purpose of this paper is to propose a Resource Description Framework (RDF)-based approach to transform metadata crosswalking from equivalent lexical element mapping into semantic mapping with various contextual relationships. RDF is used as a crosswalk model to represent the contextual relationships implicitly embedded between described objects and their elements, including semantic, hierarchical, granular, syntactic and multiple object relationships to achieve semantic metadata interoperability at the data element level.

Design/methodology/approach
– This paper uses RDF to translate metadata elements and their relationships into semantic expressions, and also as a data model to define the syntax for element mapping. The feasibility of the proposed approach for semantic metadata crosswalking is examined based on two use cases – the Archives of Navy Ships Project and the Digital Artifacts Project of National Palace Museum in Taipei – both from the Taiwan e-Learning and Digital Archives Program.

Findings
– As the model developed is based on RDF-based expressions, unsolved issues related to crosswalking, such as sets of shared terms, and contextual relationships embedded between described objects and their metadata elements could be manifested into a semantic representation. Corresponding element mapping and mapping rules can be specified without ambiguity to achieve semantic metadata interoperability.

Research limitations/implications
– Five steps were developed to clarify the details of the RDF-based crosswalk. The RDF-based expressions can also serve as a basis from which to develop linked data and Semantic Web applications. More use cases including biodiversity artifacts of natural history museums and literary works of libraries, and conditions, constraints and cardinality of metadata data elements will be required to make revisions to fine tune the proposed RDF-based metadata crosswalk.

Originality/value
– In addition to reviving contextual relationships embedded between described objects and their metadata elements, nine types of mapping rules were developed to achieve a semantic metadata crosswalk which will facilitate the design of related mapping software. Furthermore, the proposed approach complements existing crosswalking documents provided by authoritative organizations, and enriches mapping language developed by the CIDOC community.
