The tribological behaviour of Fe‐C‐Al cast iron – effect of temperature
Authors: Maleque M.A. , Sugrib S. 
Published: August 2013

PurposeThe aim of this paper is to study the tribological behaviour of Fe‐C‐Al cast iron at different temperatures using universal pin‐on‐disk machine.Design/methodology/approachThe cold set resin bonded sand mould casting process was employed to develop Fe‐C‐Al cast iron and Fe‐C‐Si cast iron. The microstructures of materials were studied using field emission scanning electron microscope. The wear and friction tests were conducted using universal pin‐on‐disk machine at 25°C, 100°C, 200°C and 300°C temperature. The worn surface was characterized using scanning electron microscopy.FindingsThe lower wear rate was found for Fe‐C‐Al cast iron compared to Fe‐C‐Si cast iron and delamination type wear morphology was observed in both types of cast iron materials. The results also showed that the friction coefficient value of Fe‐C‐Al cast iron was lower than that of Fe‐C‐Si cast iron at different temperatures. It can be concluded that the overall tribological behaviour of Fe‐C‐Al cast iron at higher temperatures was better than conventional Fe‐C‐Si cast iron.Originality/valueThe information on the development and tribological properties of the Fe‐C‐Al cast iron at different temperatures is scarce in the literature. The special type of cold set resin bonded sand mould was used for casting this Fe‐C‐Al cast iron material. Therefore, the current study is quite new and it is hoped that it will provide a high value to the automotive and other engineering researchers for the application of this material.
Static performance characteristics of hybrid journal bearings with plugged entry holes
Authors: Garg H.C. , Kumar Vijay 
Published: August 2013

PurposeThis paper aims to investigate the effect of plugging of holes on the static performance characteristics of a constant flow valve compensated hole‐entry hybrid journal bearing system operating with Newtonian and non‐Newtonian lubricants. The analysis considers the generalized Reynolds equation governing the flow of lubricant having variable viscosity in the clearance space and equation of flow of lubricant through constant flow valve restrictor. The non‐Newtonian lubricant is assumed to follow the power law. The performance characteristics are computed for the two values of power law index (n=1.0 and 0.566). The computed results indicate that the blockage of holes during operation will not be the likely causes for the imminent failure of a well‐designed non‐recessed hole‐entry hybrid journal bearing.Design/methodology/approachFinite element method has been used to solve generalized Reynolds equation governing the flow of lubricant having variable viscosity in the clearance space and equation of flow of lubricant through constant flow valve restrictor.FindingsThe computed results indicate that the blockage of holes during operation will not be the likely causes for the imminent failure of a well‐designed non‐recessed hole‐entry hybrid journal bearing. The bearing configuration with plugged holes provides sufficient fluid film thickness and low power requirement as less lubricant is required to be pumped in the bearing.Originality/valueTo the best of the author's knowledge, no study which considers the influence of plugging of holes on the static performance characteristics of a constant flow valve compensated hole‐entry hybrid journal bearing system operating with Newtonian and non‐Newtonian lubricant is yet available in the literature.

Authors: Ching Russell K.H. , Tong Pingsheng , Chen Ja‐Shen , Chen Hung‐Yen 
Published: August 2013

PurposeDrawing on extant literature on narrative persuasion, online advertising, and transportation theory, this research aims to study Internet‐based online narrative advertising and investigate the effects of four pertinent advertising design elements, interactivity, entertainment, vividness, and self‐referencing, on consumer products and the moderating effects of advertisement involvement on these relationships.Design/methodology/approachData were collected using an online questionnaire that contained measures adapted from prior studies. Participants first selected a product that they would seriously consider purchasing and answered a set of questions prior to viewing a narrative online advertisement, which was followed by a different set of questions. Structural equation modeling was used to empirically test the authors’ proposed model.FindingsGreater levels of interactivity, vividness, entertainment, and self‐referencing in narrative online advertisements led to more favorable attitudes toward a product. In particular, self‐referencing had a substantial effect on transportation in forming product attitudes. Advertisement Involvement moderates (i.e. enhances) the effect of self‐referencing on attitudes toward a product.Practical implicationsIf properly designed, a narrative online advertisement can fully utilize Internet‐enabled features and can maximize their potential to produce a favorable consumer attitude toward a featured product.Originality/valueThis study advances narrative advertising research and provides empirical evidence to highlight the effects of the pertinent characteristics of Internet‐based advertising, interactivity and entertainment in the conversion process of transportation and consumer attitudes. Moreover, this study identifies and sheds light on important contingencies (i.e. advertisement involvement) of the focal relationships.
Love Internet, love online content
Authors: Ji Pan , Wayne Fu W. 
Published: August 2013

PurposeThis study aims to examine how information and social gratifications sought by Internet users affect their affinity for the Internet or for particular types of online content.Design/methodology/approachA survey was administered in Singapore to collect data. A correlation analysis, a paired‐samplettest, and hierarchical regression analyses are conducted to address the research questions and hypotheses.FindingsAffinity for the Internet and affinity for particular types of online content are correlated and distinct. Both relate positively to social gratifications. The passive social gratification of Internet access and the active pursuit of interactions exert similar impact on both types of affinity. Information affects neither after social gratifications are controlled.Practical implicationsConstant access to online contacts or quality online interaction may facilitate social gratifications, thereby boosting user affinity for the Internet or for particular types of online content. Online information should be presented interactively to attract and retain users. The selection of online content and applications should also be made easier to cultivate a loyal user market.Originality/valueThis study contributes to U&G theory by adapting a television‐based proposition to cyberspace, and examining the attitudinal effect of online social gratifications involving different levels of user activity.
Sales coordination and structural complexity: a national‐international comparison
Authors: Rehme Jakob , Kowalkowski Christian , Nordigården Daniel 
Published: August 2013

PurposeThe existing literature on key account management (KAM) has focused more on sales forces and management levels than on their evolution. The purpose of this paper is to explore how sales activities can be coordinated to accommodate national and international KAM programs.Design/methodology/approachThe paper is based on a longitudinal study of the industrial conglomerate ABB, 1996‐2008.FindingsThe diversity associated with geography and product complexity creates demands for a more flexible organization that can provide a more complete offering portfolio across national boundaries and still handle the demands of local organizations. In addition to internal organizational contingencies, the key factors and driving forces for the development of KAM programs are the marketing and purchasing strategies that buyer and seller firms perceive and encounter.Research limitations/implicationsThe data are limited to one corporation and some of its key customers in different industries. Although the internal and construct validity of the findings are strong, the external validity cannot be assessed precisely.Originality/valueThe 12‐year study brings valuable insights to the development of KAM programs in multinational corporations and addresses coordination issues related to geographical and product complexity.
Application of customer lifetime value model in make‐to‐order manufacturing
Authors: Tukel Oya I. , Dixit Ashutosh 
Published: August 2013

PurposeThe applicability of the customer life time value (CLV) concept goes beyond consumer markets. Specifically, the purpose of this paper is to show how a make‐to‐order manufacturing company in a supply chain can set customer‐focus manufacturing strategies using CLV.Design/methodology/approachData from an integrated steel plant is used to calculate the life time value of customers based on the past value, the potential value, and their loyalty. The past value of a customer is based on the historical data and the future value of a customer is then forecasted. The loyalty index of a customer is determined by survey results.FindingsIn general, it was found that the CLV for the most valuable customers increases exponentially and the top 28 percent of customers constitute 80 percent of the total value of all customers.Research limitations/implicationsThis study focuses on make‐to‐order manufacturing organizations and the three strategies suggested for business process improvement need to be re‐evaluated for make‐to‐stock or mass production.Practical implicationsBased on these results, the authors suggest three strategies for business process improvement and revenue growth for the plant.Originality/valueThis study constitutes an initial effort to develop a CLV model for make‐to‐order manufacturing organizations for improving plant performance. The model links customers with not only the front office functions but also with ERP systems. Organizations that are part of value chains can benefit significantly from CLV applications.
Entrepreneurial migration: characteristics, causes and effects
Authors: Thi Thanh Thai Mai , Turkina Ekaterina 
Published: August 2013

PurposeThe purpose of this paper is to introduce the special issue on “Entrepreneurial migration: characteristics, causes and effects”.Design/methodology/approachLiterature review.FindingsStudies on immigrant entrepreneurship have become increasingly popular and the importance of social context and social connections has been recognized by scholars. However, research on their effects on immigrant entrepreneurship has been rather limited. This special issue explains the essential steps of the entrepreneurial process by immigrants (i.e. host country choice, entrepreneurial engagement, new venture creation, business network development and corporate political activities) and discusses the effects of immigrant entrepreneurs on their host countries.Originality/valueThe paper presents a review of literature on entrepreneurial migration and social impacts.
Immigration, education and entrepreneurship in developed countries
Authors: Neupert Kent E. , Baughn C. Christopher 
Published: August 2013

PurposeThe purpose of this paper is to provide a country‐level consideration of the relationship between entrepreneurship, immigration and education. In contrast to studies that report on immigration and entrepreneurship in a region or single country, the authors seek to determine whether levels of immigration, and the level of education obtained by the immigrants, are predictive of levels of entrepreneurship activity. A common set of variables and data from developed countries are used to test the hypothesized relationships.Design/methodology/approachUsing data on 21 OECD countries and five measures of entrepreneurship from the Global Entrepreneurship Monitor project, the authors assess the significance of immigration and education level on entrepreneurial activity using regression analysis.FindingsThe stock of immigrants in a country was found to be predictive of the proportion of that country's population involved in starting and managing a new business (early stage entrepreneurship), as well as the growth expectations held by those early‐stage entrepreneurs. Also, levels of high growth and high growth expectation entrepreneurship were predicted by the proportion of more highly‐educated immigrants.Originality/valueThis study provides national‐level comparative evidence linking entrepreneurial activity to immigration and to the level of education obtained by those immigrants, thereby adding to our understanding of immigration, education and entrepreneurship. The results have implications for the immigration policies of countries seeking to add to their economic base by encouraging entrepreneurship and job creation.
An emerging African business quarter amid urban decline
Authors: Barrett Giles Andrew , McEvoy David 
Published: August 2013

PurposeThe purpose of this paper is to describe and assess the sustainability of an emergent West African business quarter in Manchester, UK. Comparisons are drawn with developments among other ethnic groups. The research is placed in the context of international literature on ethnic entrepreneurship.Design/methodology/approachThe research is primarily qualitative, using semi‐structured interviews and conversational life histories with a sample of West African retail businesses and a comparative group of other local businesses. Some use is made of quantitative information from census and other public data sources.FindingsNew West African enterprises appear, over the last few years, to have stabilised the declining retail district of Moston Lane in north Manchester. These new businesses are however confined to few sectors: food stores, hair and beauty salons, cafes, Internet cafes and clothing shops. These developments may parallel the success of longer established retail quarters in Manchester and elsewhere. However, most of the businesses may not survive long, having provided a temporary living, and some entrepreneurial experience, for their owners.Research limitations/implicationsLimited sample size and short time frame make results exploratory rather than definitive. The research provides however a base for future investigations.Practical implicationsThe businesses studied provide economic opportunities for some immigrants with limited labour market opportunities.Social implicationsImmigrants are helped to maintain the integrity of their culture through the purchase of appropriate goods and services.Originality/valueThis paper provides the first consideration of a specifically African retail quarter in Britain, adding an additional ethnicity to the roster of identifiable geographic business locations.
Using Web 2.0 technologies for communication, collaboration and community building: a Caribbean perspective
Authors: Wood Beverley A. 
Published: August 2013

PurposeThis paper aims to demonstrate how Web 2.0 technologies may be used to counter some of the challenges encountered traditionally by the Caribbean library and information science (LIS) field.Design/methodology/approachThis paper explores the key features of each Web 2.0 technology discussed and then shows how these characteristics might be beneficially applied to resolve or alleviate one of the challenges explored.FindingsBy providing examples of best practice the paper shows that there are Web 2.0 technologies being used by the LIS community in the Caribbean to encourage wider communication, collaboration and community building. It notes however that there are still more emerging technologies which may be successfully used to overcome other traditional challenges.Originality/valueThe paper adds a Caribbean perspective to the Web 2.0 discussions. It also demonstrates how emerging/Web 2.0 technologies might effectively be used as problem solving tools.

Workplace bullying and the challenge of pre‐emptive management
Authors: Beirne Martin , Hunter Paul 
Published: August 2013

PurposeThe purpose of this paper is to take a critical look at anti‐bullying initiatives at work. It questions current prescriptive thinking about effective ways of tackling workplace bullying, illuminating neglected contextual conditions and organizational constraints that affect attempts to develop and sustain pre‐emptive management programmes.Design/methodology/approachA qualitative case approach was employed for a comparative analysis of two anti‐bullying initiatives: one each in the public and private sectors.FindingsThe case results challenge the popular belief that business needs provide an impetus to coherent action against mistreatment at work, revealing the significance of local reactions and the mediating influence of competing subcultures and group identities on the “working out” of formal initiatives.Research limitations/implicationsThis research underlines the importance of extending bullying research to include more in‐depth and applied work on the problems of enacting and sustaining anti‐bullying initiatives.Practical implicationsEffective action against bullying involves more than policy making, rule forming and guideline setting. It is important to cultivate the resilience of those at the sharp end of anti‐bullying projects, and engage with managers and employees who experience difficulties or confront unpalatable changes to their work situation as anti‐bullying initiatives develop.Originality/valueThis article casts light on an under‐researched area, since available literature concentrates on the underlying causes and consequences of workplace bullying. Prescriptions for tackling the problem tend to be drawn out of causal and impact studies with limited empirical evidence about their viability, or analysis of possible constraints on their implementation.
Social entrepreneurship – innovative challengers or adjustable followers?
Authors: Gawell Malin 
Published: August 2013

PurposeSocial entrepreneurial initiatives are often ascribed innovative roles for the public good. However, it is also argued that the same initiatives react to conditions in different contexts as well as to local or global trends. But, what roles and values are brought into practice by initiatives today and how can these be conceptualised as innovative? The aim of this paper is to empirically describe and analyse social entrepreneurship initiatives and contribute to the understanding of their role in the development of society.Design/methodology/approachThe paper is based on a framework focusing on entrepreneurial dynamics, organisations and institutions. Empirically, it is grounded in four studies of social enterprises and their entrepreneurial initiatives in Sweden.Findings– The results reveal an intricate interplay between innovative challenges and institutional inertia as well as a combined role for social entrepreneurship initiatives in which innovative aspects can be more or less extensive.Originality/valueThe study contributes to problemising and nuancing the understanding of social entrepreneurship and social enterprises in relation to innovation in society.
Managers' competences in social enterprises: which specificities?
Authors: Moreau Charlotte , Mertens Sybille 
Published: August 2013

PurposeThe management of an organisation and the context within which this organisation evolves are recognised as two important aspects of any organisation. Few studies have been conducted however on the management function within the specific context of social enterprises, organisations that mix social goals and economic imperatives. This paper aims to examine the specific competences of management in social enterprises, by constructing a competence model, the emblematic tool of competence‐based management, relevant to the management of social enterprises.Design/methodology/approachThe authors hypothesise that certain competences required of managers in social enterprises are specific, regarding the particular internal and external context of social enterprises, the governance model, etc. The methodology used is based on four main steps: a review of the literature and the conducting of exploratory interviews, the construction of a first draft of the competence model, the conducting of group interviews with managers of social enterprises in six European countries as this research takes place within the framework of a European research project on lifelong learning, and the final adaptation and validation of the competence model.FindingsSeven main competences specific to the context of social enterprises emerge, each one being further developed as knowledge, skills, and competences.Originality/valueThe paper illustrates the interest in building up a competence model for the management of social enterprises.
Culture change enables ambitious growth at Nelsons
Authors: Rickatson Simon 
Published: August 2013

PurposeThis paper aims to examine how the oldest manufacturer of natural healthcare products in Europe, Nelsons, needed to make a leap in its development to take advantage of the opportunities in export markets and to meet ambitious production and revenue targets.Design/methodology/approachThis case study follows how Nelsons put in place a new culture among managers to achieve its growth targets, which involved moving away from being the custodians of a traditional brand towards leadership of a fast‐moving global enterprise. A management development scheme was introduced to support the fundamental changes, to create a new cadre of staff with the skills and confidence to lead, and overcome the discomfort which can come from rapid and wide‐ranging change.FindingsIf there is a good team of staff prepared to lead as much as manage change, implementing major initiatives can become relatively easy.Originality/valueThe paper illustrates that the program demonstrated the importance of creating leaders for change, which have underpinned record outputs at the firm and strong progress towards the overall targets.
Employee engagement welcomes the dawn of an empowerment culture
Authors: Cattermole Gary , Johnson Jaime , Roberts Karen 
Published: August 2013

PurposeThis paper seeks to address the role and impact of employee engagement within an organization undergoing cultural transformation, addressing the issues of monitoring and increasing levels of staff engagement over time.Design/methodology/approachThe paper draws on in‐depth employee engagement surveys over a five year period as part of a case study to illustrate how HR drives and monitors change through employee engagement.FindingsThis paper follows a company through enormous organizational change, firstly towards a high performance culture and then to a culture of empowerment. The role of engagement and monitoring processes are highlighted as part of the transition.Research limitations/implicationsThe case study does not offer a true multinational case study as only a small proportion of employees are based overseas.Originality/valueThis paper illustrates how an international organization can deliver organizational change and build employee engagement to drive the business forward. The case study offers best practice material for HR managers.
