Authors: Lin Jaw‐Ren , Chou Tsu‐Liang 
Published: January 2013

PurposeThe purpose of this paper is to provide more information for fluid‐film bearing selection and designing. The present paper is mainly concerned with the dynamic characteristics of a wide composite slider bearing lubricated with non‐Newtonian couple stress fluids.Design/methodology/approachTaking into account the non‐Newtonian couple stress effects resulting from a Newtonian lubricant blended with additives, the non‐Newtonian dynamic coefficients are obtained for composite slider bearings.FindingsComparing with the non‐Newtonian inclined‐plane bearing, the non‐Newtonian composite bearing provides an improvement in the dynamic stiffness and damping coefficients; better bearing characteristics are achieved for the non‐Newtonian composite bearing under specific length‐ratio parameters.Originality/valueThe paper includes a numerical example to provide guidance for non‐Newtonian composite slider bearings.
Research on experiments with water vapor as coolant and lubricant in drilling Ti6Al4V
Authors: Wu Jian , Di Han Rong 
Published: January 2013

PurposeThe purpose of this paper is to develop water vapour as a new cooling and lubricating technique in drilling Ti6Al4V. Water vapor is an economical and eco‐friendly coolant and lubricant. However, it is necessary to study the drilling chip deformation, forces and drilling temperature when drilling Ti6Al4V using this new green drilling technology, which meets the development trend of green machining technology.Design/methodology/approachComparative experiments are carried out with HSS drill bits and YG6X (K10 type in ISO) cemented carbide drill bits in drilling Ti6Al4V under the conditions of oil water emulsion, water vapor as coolant and lubricant and dry drilling, respectively. The drilling forces, temperature and drill bit wear VBmax have been examined and analyzed. Further, a new type practical drilling quick‐stop device is developed for studying the chip deformation in drilling Ti6Al4V. The drilling forces distribution test in drilling Ti6Al4V is also developed.FindingsWhen water vapor is used as coolant and lubricant, the torque is reduced by 15‐25%, 5‐10% in comparison with dry drilling and oil water emulsion, respectively; the thrust is reduced by 5‐10%, 4‐5%; the temperature is reduced by 15‐20%, 5‐8% and the wear VBmax of drill bit is reduced by 60‐80%, 10‐15%, correspondingly. Also, the contact length in chip‐tool interface decreases and the drilling deformation is reduced. The coolant and lubricant conditions and feed rate have little impact on the drilling force distribution in drill bit cutting edges.Originality/valueA green machining technology, water vapor used as coolant and lubricant, is used in drilling Ti6Al4V; it can reduce drilling deformation, drilling forces, temperature and flank wear. A new drilling quick‐stop device is devised to obtain the drilling chip roots. Also, the drilling force distribution test was developed for obtaining the rate of drilling forces in cutting edges when drilling Ti6Al4V.
The practice of corporate social responsibility by Malaysian developers
Authors: Yam Sharon 
Published: January 2013

PurposeThe purpose of this research is to assess the implementation of sustainable practice by Malaysian property developers, particularly on social and environmental perspectives.Design/methodology/approachThis is a qualitative research where content analysis is used to analyse leading property companies’ websites, annual reports, corporate responsibility and sustainability reports, and carbon disclosure reports.FindingsFindings from this research indicate that the majority of the developers have their corporate social responsibility (CSR) initiatives in place and there are variations in their approaches and reporting process. Of all, philanthropic activities are the mostly widely reported followed by human resource initiatives. Even though the majority of property companies reported their environmental practices, only the top few developers had their projects certified by sustainability rating agencies.Research limitations/implicationsAs this project was restricted to the top ten Malaysian developers, the results do not reflect how other companies, particularly the smaller ones, adopt CSR in their business. However, this project revealed valuable findings regarding the magnitude of CSR initiatives, particularly on social and environmental perspective, adopted by the top ten Malaysian property developers; this is useful for the Malaysian government authorities in formulating CSR‐related policies particularly on environmental sustainability. As well, the findings of this project can be a useful reference to other property companies which are keen to contribute to sustainable development, particularly on social and environmental perspectives.Originality/valueThere has been limited literature on CSR in the Malaysian property industry thus far. Previous research papers are mainly about environmental sustainability of property companies, sustainable practice by Malaysian real estate investment trusts, and CSR perception of house buyers and developers. Therefore, to fill the gap in the literature, this research is designed to assess the implementation of sustainable practice by Malaysian property developers, particularly on the social and environmental perspectives.

Authors: Jewell E.H. , Hamblyn S.M. , Claypole T.C. , Gethin D.T. 
Published: January 2013

PurposeThe purpose of this paper is to carry out a comprehensive experimental investigation into the role of screen and conductive carbon material formulation on line conductivity and printing capability in the screen printing process, to provide design knowledge and further understanding of the screen printing for printed carbon.Design/methodology/approachA full factorial experiment was carried out where six carbon materials were printed through ten screens to a polyester substrate under a set of standard conditions.FindingsMaterial characterization showed that viscosity and the corresponding viscous and elastic material modulli increased with solids content and that the elastic properties at low shear are significant. The solids carbon content materials were unable to produce the minimum printable line features possible with the low carbon materials. Increasing the solids contents reduced the final cured line resistance, reduced the printed line width, increased the film thickness, increased the cross sectional area and reduced the material resistivity. Material resistivities were around 700 to 950 μΩcm were obtained in the printed lines.Research limitations/implicationsLower material resistivities were obtained with higher solids materials and it is postulated that the increased visco‐elastic nature of the solids content materials, play a role in determining the microscopic structure of the cured film through alignment of the carbon graphite platelets.Practical implicationsA dataset which allows material, screen and print characteristics has been created allowing process optimization and formulation development to be accelerated.Originality/valueThe work provides insight into the role of material properties and process settings on the electrical and physical characteristics of printed carbon.
The influence of brand equity on consumer responses
Authors: Buil Isabel , Martínez Eva , de Chernatony Leslie 
Published: January 2013

Purpose
– The purpose of this paper is to propose and test a model to better understand brand equity. It seeks to investigate the effects of this construct on consumers
'
responses using data from two European countries.

Design/methodology/approach
– Hypotheses were tested using structural equation modeling (SEM). Measurement invariance and stability of the model across the two national samples was assessed using multigroup confirmatory factor analysis.

Findings
– Results indicate that brand equity dimensions inter-relate. Brand awareness positively impacts perceived quality and brand associations. Brand loyalty is mainly influenced by brand associations. Finally, perceived quality, brand associations and brand loyalty are the main drivers of overall brand equity. Findings also corroborate the positive impact of brand equity on consumers
'
responses. In addition, the general framework proposed is found to be empirically robust across the studied countries. Only a few differences are observed.

Research limitations/implications
– A limited set of product categories, brands and countries were used.

Practical implications
– Findings provide useful guidelines for brand equity management. Managers can complement financial metrics with consumer-based brand equity measures to track brand performance over time and to benchmark against other brands. Building brand equity generates more value for corporations since a more favourable consumer response results from positive brand equity.

Originality/value
– This study contributes to the scarce international brand equity literature by testing the proposed model using data from a sample of consumers in two European countries. It also enriches the brand equity literature by empirically examining the relationships among consumer-based brand equity dimensions and its effects on consumers
'
responses.
Development opportunities in the “new” NHS for personal, population and system care
Authors: Colin‐Thomé David 
Published: January 2013

PurposeThe aim of this paper is to set out the role of clinical governance within the new commissioning framework. It starts by considering the historical development of clinical governance and lays out ideas for the new arrangements around the concept of the primary care home and concludes with challenging questions for the future.Design/methodology/approachThe paper draws on the author's role and experience as a senior policy maker in the UK Department of Health.FindingsIf we are to fulfil the defined attributes of clinical governance the NHS needs to adopt a more reflective self‐auditing leadership culture. Whether that supposition is accepted or not, a set of questions arises. Why, given for instance the gross failures of care for the frail elderly, have the principles of clinical governance not been systematically embedded? Why, given the NHS can no longer be described as poorly resourced, are clinical outcomes for many conditions lagging behind equivalent international healthcare systems? Why have the improved access and clinical outcomes of recent years been dependent on political rather than NHS leadership? And why in our publicly funded NHS is there frequently a culture of regarding patients as grateful supplicants rather than true partners to whom we should account? Clinical governance for personal, population and system care. Does this represent a coming of age?Originality/valueThis article provides a contribution to the emerging policy debate around clinical governance in the new commissioned NHS, rooted in experience from both the clinical front line and the heart of national health policy making.
Viewing engineering offshoring in a network perspective: addressing and managing risks
Authors: Nadja Lee Hansen Zaza , Zhang Yufeng , Ahmed‐Kristensen Saeema 
Published: January 2013

PurposeCompanies are increasingly engaged with global engineering networks through offshoring of product development activities from R&D to production. This creates many new challenges as operations get physically and culturally decoupled. The purpose of this paper is to improve understanding of how to effectively manage engineering offshoring activities in a context of global engineering networks. The main research question, therefore, is: “Can offshoring of engineering tasks be explained and managed using the concept of Global Engineering Networks (GEN)?” Effective approaches to handling the associated risks of engineering offshoring will be a key area of the investigation.Design/methodology/approachThe research approach is based on the engineering design research methodology developed by Blessing and Chakrabarti, including a descriptive phase and a prescriptive phase. Four case studies of large multinational corporations in Denmark were carried out. Data gathering was mainly documentary studies and interviews. The main data analysis approaches were coding (Strauss and Corbin) and pattern‐matching (Yin). The dataset was analysed using the GEN framework suggested by Zhang et al. and Zhang and Gregory.FindingsEngineering offshoring presents companies with challenges related to communication and knowledge sharing which is addressed through formal and informal mechanisms as well as a more streamlined operation. However, this did not remove the challenges. The GEN framework suggests a systematic approach to understanding global engineering networks through investigating their contextual features, critical capabilities to compete in a particular contextual circumstance, and configuration characteristics to deliver the capabilities. Using the GEN framework, the challenges faced by companies and the risks associated with their engineering offshoring activities can be explained as a mismatch between the required capabilities and the companies' ability to deliver these capabilities.Originality/valueThis paper provides new theoretical insight into both engineering offshoring and GEN theories by extending the GEN framework to address complications within engineering offshoring. This strengthens both academic fields, and will be able to help engineering managers to develop appropriate engineering network configurations for offshore engineering operations.
An integrated methodology to prioritise improvement initiatives in low volume‐high integrity product manufacturing organisations
Authors: Marriott Ben , Arturo Garza‐Reyes Jose , Soriano‐Meier Horacio , Antony Jiju 
Published: January 2013

PurposeSeveral authors have proposed different approaches to help practitioners deal with the complexity of prioritising improvement projects and initiatives. However, these approaches have been developed as “generic” methods which do not consider the specific needs, objectives and capabilities of different industries and organisations. The purpose of this paper is to present an integrated methodology that prioritises improvement projects or initiatives based on two key performance objectives, cost and quality, specifically important for low volume‐high integrity product manufacturers.Design/methodology/approachThe paper reviews some of the most commonly used prioritisation methods and the theory and logic behind the proposed prioritisation methodology. Then, the prioritisation methodology is empirically tested, through a case study, in a world class manufacturing organisation.FindingsThe results obtained from the case study indicate that the integrated methodology proposed in this paper is an effective alternative for low volume‐high integrity products manufacturers to identify, select and justify improvement priorities.Practical implicationsSelection and prioritisation of projects and initiatives are key elements for the successful implementation of improvements. The integrated methodology presented in this paper intends to aid organisations in dealing with the complexity that is normally handled over the selection and prioritisation of feasible improvement projects.Originality/valueThis paper presents a novel methodology that integrates two commonly used approaches in industry, Process Activity Mapping (PAM) and Failure Mode and Effect Analysis (FMEA), to prioritise improvements. This methodology can help, in particular, organisations embarked in the manufacture of low volume‐high integrity products to take better decisions and align the focus of improvement efforts with their overall performance and strategic objectives.
From puffery to penalties: a historical analysis of US masked marketing public policy concerns
Authors: Petty Ross D. 
Published: January 2013

PurposeThis article aims to examine the US history of practices that mask the marketing content of messages to consumers and of the public policy approaches taken towards such practices.Design/methodology/approachThis research examines both primary sources such as legal challenges and contemporary writings as well as secondary sources.FindingsThe US legal/regulatory system has been examining practices that mask the marketing content of communications for over 125 years. Fully masked messages were initially regulated under postal service laws and publisher self‐regulatory codes. Partially masked messages, e.g. testimonials, were examined first by courts and later by regulatory and industry self‐regulatory agencies. These diverse sources of regulation led to diverse approaches and in part explain the modern preference for information disclosure over prohibiting the masking of marketing messages.Originality/valueModern analysis of these practices ignores their history and the historical evolution of their regulation. This article not only reveals a rich regulatory history, but also suggests that modern policy should treat the broad array of masking practices consistently and correct current policy approaches that are based on historical development rather than modern public policy analysis and concerns.
Income vs price subsidy: policy options to help the urban poor facing food price surge
Authors: Chunyan Huang , Funing Zhong , Jun He 
Published: January 2013

PurposeThe purpose of this paper is to analyze and compare the costs of price and income subsidies when the food security policy targets the urban poor. The result may help policymakers choose a desired subsidy scheme to ensure food security for the urban poor facing food price surge.Design/methodology/approachThe analysis consists of three parts: constructing an empirical model on provincial panel data in 1993‐2009 estimating the impact of grain price on food security among urban residents by different income level; evaluating the potential costs of shifting to income subsidy aiming to maintain the real income levels of the low income, lowest income or the poor residents if grain price increases by 20 percent; and comparing with the cost of price subsidy to achieve the same policy goal.FindingsThe paper finds that, food price surge will hurt the urban poor much more seriously than the high income population; the rich residents may receive more benefit from price subsidy; and income subsidy has obviously a cost advantage while the targeted people benefit more.Originality/valueThe obvious value of the paper is to show that income subsidy is much more desired than price subsidy, if the policy goal is to help the poor during food price surge.
A typology of food security in developing countries
Authors: Yu Bingxin , You Lingzhi 
Published: January 2013

PurposeThe recent high food price and volatility, as well as economic recession, have reversed the last decade's progress in reducing hunger and poverty. This aim of this paper is to conduct a factor and sequential typology analysis to identify groups of countries categorized according to five measures of food security.Design/methodology/approachThe recent high food price and volatility, as well as economic recession, have reversed the last decade's progress in reducing hunger and poverty. This paper conducts a factor and sequential typology analysis to identify groups of countries categorized according to five measures of food security – consumption, production, imports, distribution, and agricultural potential – by using indicators from 175 countries. The analysis first identifies five distinct food security groups, measured by the levels of nutrient intake, and then further splits these groups based on indicators of food production, trade security, and agricultural potential.FindingsThe results suggest that the terms of “developing country” or “low income country” can be inaccurate in the discussion of food security because they are too general and can actually mask the extreme heterogeneity in different aspects of food security. The results also indicate that different responses are needed by different types of food‐insecure countries to address their unique food and economic challenges.Originality/valueThe typology of food security and linkage between agricultural potential and food security contribute to a better understanding of the effectiveness of different policy interventions under a country's unique conditions.
Conflict analysis based on the graph model for conflict resolution and grey matrix
Authors: Han Xueshan , Dieu Linh Nguyen Thi , Xu Haiyan 
Published: January 2013

PurposeThe purpose of this paper is to propose a complete theory of grey conflict analysis model based on grey game and the graph model for conflict resolution and also, to illustrate a case of “prisoner's dilemma” in the traditional grey game as an example.Design/methodology/approachBased on the theories of grey game and graph model for conflict resolution, this paper concentrates on the model of grey conflict analysis in a case of two players under the condition of symmetrical loss information. By analyzing decision makers, strategies, states, graph model and grey potential, and the number of decision makers' steps, the pure strategy Nash equilibrium is extended to grey potential‐general metarationality, grey potential‐symmetrical metarationality, and grey potential‐sequential stability. Meanwhile, the logical relationships between solutions are discussed. A specific case study is carried out to illustrate how the proposed grey conflict analysis model is used in practice.FindingsThe results in this paper indicate that more stable solutions are found when one considers the grey potential‐general metarationality, the grey potential‐symmetrical metarationality, and the grey potential‐sequential stability, and then solve the paradox of “prisoner's dilemma”.Practical implicationsThis new grey conflict analysis model could be used to provide useful information for policy makers during existing conflicts or negotiations among parties or enterprises.Originality/valueThe paper succeeds in constructing a new grey conflict analysis model, in which the solution concepts are studied; and the two‐player grey game will be extended to n‐players in the near future.
Vibrio parahaemolyticus type IV pili mediate interactions with diatom‐derived chitin and point to an unexplored mechanism of environmental persistence
Authors: Frischkorn Kyle R. , Stojanovski Asta , Paranjpye Rohinee 
Published: January 2013

SummaryVibrio parahaemolyticus is a naturally occurring bacterium common in coastal waters where it concentrates in shellfish through filter feeding. The bacterium is a human pathogen and the leading cause of seafood‐borne gastroenteritis. Presently there is little information regarding mechanisms of environmental persistence of V. parahaemolyticus or an accurate early warning system for outbreak prediction. Vibrios have been shown to adhere to several substrates in the environment, including chitin, one of the most abundant polymers in the ocean. Diatoms are abundant in estuarine waters and some species produce chitin as a component of the silica cell wall or as extracellular fibrils. We examined the role of specific surface structures on the bacterium, the type IV pilins PilA and MshA, in adherence to diatom‐derived chitin. Biofilm formation and adherence of V. parahaemolyticus to chitin is mediated by the ability of the bacterium to express functional type IV pili. The amount of adherence to diatom‐derived chitin is controlled by increased chitin production that occurs in later stages of diatom growth. The data presented here suggest late‐stage diatom blooms may harbour high concentrations of V. parahaemolyticus and could serve as the foundation for a more accurate early warning system for outbreaks of this human pathogen.
