The effect of dye molecules in titania‐silica hybrid coatings for corrosion protection
Authors: Rout Tapan Kumar 
Published: November 2010

PurposeThe purpose of this paper is to develop a corrosion resistant zinc‐free coating for interstitial free steel.Design/methodology/approachThe objective was achieved by developing a titania‐silica hybrid coating through a sol‐gel process by incorporating a dye molecule. The role of dye molecules was particularly important for enhancing the anti‐corrosion properties of the coating. The approach of current research was to develop a low‐temperature coating process that can bring similar performance to that obtained in case of zinc coating. Titania and silica precursors were mixed by stirring under a nitrogen atmosphere at 80°C to formulate a low‐temperature coating. The dye molecules were added before addition of water for subsequent hydrolysis. This complete formulation was applied over steel sheets using a roll coater as the application method.FindingsThe ranking order of improved corrosion resistance was found to be PATMS>EETMS>GPTMS and the addition of trace amount of tartrazine dye (60‐65 mg/l of liquid) in PATMS increased the corrosion service life in saline environments from 168 to 216 h, thus showing a promising improvement. Scanning Kelvin Probe results indicated that the corrosion reaction is controlled cathodically in presence of dye and, electrochemical impedance spectroscopy results exhibited a charge transfer resistance (Ct) of coating with dye of 419Ω cm2, which was higher than that of a similar coating without dye (360Ω cm2), indicating increased corrosion protection.Research limitations/implicationsThis coating had improved barrier protection but lacked cut edge protection. Future work will focus on adding sacrificial protection by introducing compatible corrosion inhibitors, especially dye molecules, which are photosensitive.Practical implicationsThis coating has huge potential for use in the automotive sector, especially for certain automotive parts (i.e. helm flanges), which suffer from poor durability in salty and high‐humidity atmospheres.Social implicationsSince this coating formulation utilises a partially aqueous base, some environmental impact cannot be avoided, but it will have less impact than a complete solvent base formulation.Originality/valueThe novelty of the work was the introduction of dye molecules as the corrosion inhibitor and their compatibility in the hybrid coating system.
High‐pressure CO2 pretreatment as a method for stainless steel passivation
Authors: Slemnik M. , Pečar D. 
Published: November 2010

PurposeThe purpose of this paper is to present a study of corrosion properties of the highly corrosion‐resistant stainless steel Prokron 11Nb, which is suitable for use in high‐temperature and high‐pressure systems.Design/methodology/approachProkron 11Nb was immersed in 0.1 M H2SO4 that had been previously sparged with CO2 and was exposed to high pressures within the range of 1‐300 bar at a constant temperature of 25°C. Treated surfaces were scanned with an electronic microscope (scanning electron microscope) equipped with energy spectrum distribution (energy dispersive spectroscopy) to analyze the morphologies and compositions of surface deposits. Corrosion properties were measured using the potentiodynamic method and electrochemical impedance spectroscopy.FindingsThe corrosion rate decreased with increasing CO2 pressure, which accelerated surface passivity, but only up to a pressure of 200 bar. Higher pressures (300 bar) increased the corrosion rate. The trends in corrosion rate with CO2 pressure agree with the stability of a protective layer where iron carbonate is present.Originality/valueA high‐pressure CO2 treatment at low temperature is found to be a useful method for improving the passivity of stainless steel. Iron carbonate, which is the result of CO2 corrosion, forms a stable protective layer on the steel surface and this lowers the corrosion rate.

Published: November 2010

PurposeThe purpose of this paper is to study the corrosion resistance and the insulating characteristics of an environment‐friendly chromium‐free coating on electrical steel.Design/methodology/approachA water‐based semi‐inorganic environment‐friendly insulating coating on electrical steel was developed. The coating system of silane coupling agent and rare earth salt were used first in this coating to replace the chromate containing coating. In this study, it provided a successful combination of coating and passivation.FindingsSeveral test results, such as insulating ability, corrosion resistance, adhesion strength and hardness, showed that the performance of the film complied fully with the industry standards, particularly excellent in its corrosion resistance and the maximum corrosion resistance (neutral salt‐spray test) time up to 20 h.Originality/valueThere have been few reports on the chromium‐free insulating coating on electrical steel, and described in the paper, this environment‐friendly insulating coating on electrical steel was found to be highly effective.
Bond between galvanized steel and concrete prepared with limestone aggregates
Authors: Maldonado L. , Quiroz‐Zavala Omán , Díaz‐Ballote Luis 
Published: November 2010

PurposeThe purpose of this paper is to elucidate if there is a loss in bond strength between galvanized steel used as reinforcement, and concrete of water‐to‐cement (w/c) ratio of 0.4 and 0.5, after both types of sample were cured for seven, 21 and 28 days in saturated calcium hydroxide solution, and without curing. The air permeability of the concrete was investigated at the interfacial zone.Design/methodology/approachStructural low‐carbon steel and galvanized steel were embedded in concrete samples, prepared with Portland cement type I and limestone (calcite 94‐97 percent) aggregates. The bond strength between the concrete and the reinforcing bars was measured by means of pull‐out tests.FindingsIn concrete of w/c=0.4 the bond for galvanized steel was 5.4±0.5 MPa, while the bond for black steel was 5.8±0.5 MPa, which is 7 percent higher than bond strength measured for samples with galvanized steel rebars. The bond strength for galvanized steel in concrete with a w/c ratio 0.5 was 5.5±0.6 MPa, which was 9 percent higher than the values obtained for black steel, which was 5.0±1 MPa. The total average bond strength of galvanized steel in concrete of w/c ratio 0.4 (5.4±0.5 MPa) and w/c ratio 0.5 (5.5±0.6 MPa) was very similar. They differed by only 2 percent. No decrease in the air permeability at the interfacial zone concrete/galvanized steel was found due to curing.Originality/valueThis research gives quantitative data on the behavior of galvanized steel used as reinforcing bars in concrete, prepared with limestone aggregates. The results might help to increase the reliability of galvanized reinforcing steel used in infrastructure exposed to very aggressive tropical humid marine environments.
Open products, open interfaces, and Ex Libris open‐platform strategy
Authors: Sadeh Tamar 
Published: November 2010

PurposeThe purpose of this paper is to describe a hybrid model of library software development, according to which libraries implement commercial software products and extend them with locally developed or community developed open‐source components.Design/methodology/approachThe paper draws on the following sources to describe several approaches to providing software that addresses the specific needs of individual libraries: commercial and community organizations' public statements of aims, philosophies, policies, and processes; e‐mail interviews; and e‐mail discussion lists. Data from a customer‐accessed collaborative web site are offered in an examination of the approach taken by one vendor, Ex Libris, to developing and supporting systems that customers can extend, customize, and integrate with other systems.FindingsA little more than a year after the Ex Libris open‐platform program was launched, active community interaction in the creation and sharing of code extensions to the vendor's commercial systems was observed.Practical implicationsCommunity initiatives, a long part of the library tradition, are becoming common in library software development. Very few libraries have the resources required to carry out large software projects; however, by leveraging the resources of the community to develop and exchange code that enhances and customizes commercial solutions, all libraries, regardless of their resources, stand to benefit from commercial solutions in a cost‐effective way.Originality/valueLibraries that are in the market for a software solution and are comparing commercial products with open‐source initiatives can benefit from this description of a hybrid model in which libraries maximize their investment in a commercial product by leveraging their staff's expertise and community support.
Cutting the proprietary cord
Authors: Helling John 
Published: November 2010

PurposeThe purpose of this paper is to compare the two leading open source library management system (LMS) packages.Design/methodology/approachThe paper highlights the reasons behind a switch from one open source provider to another. It is based on practical experience.FindingsBoth main open source LMSs (Koha and Evergreen) are presented in terms of their current use as well as their future directions of development and opportunities.Originality/valueThis paper compares the history of Koha and Evergreen. The former is criticized because of the recent “fork”, i.e. commercial use of open source code. Problems with a local implementation of Koha are also discussed. Evergreen however, since it was developed by a library consortium, appeared the better choice for the Indiana Shared Library Catalog (ISLC), a consortium of different libraries in Indiana. ISLC runs through the Indiana Cooperative Library Services Authority.
Open source software use in libraries
Authors: Payne Alexandria , Singh Vandana 
Published: November 2010

PurposeIn order to provide a general context for library implementations of open source software (OSS), the purpose of this paper is to discuss the existing presence of OSS in libraries, the functionality and variety of OSS products, and the need for further study into the application of OSS technologies in libraries.Design/methodology/approachThe paper is based on a literature review.FindingsThis paper endeavors to provide a broad overview of the deepening relationship between libraries and OSS. Libraries are seeking alternatives to proprietary applications which may require specialized support and/or services. Moreover, OSS and proprietary products have a functional verisimilitude, and, as proprietary applications developers anticipate user needs, so too do OSS contributors.Practical implicationsThe degree of variance between proprietary and OSS applications, features, support, and compatibility is continually lessening, so libraries are increasingly making use of less costly alternatives to subscription based tools.Originality/valueThe use of OSS in libraries is an increasing trend. OSS tools and implementations provide library institutions with access to a dynamic and cost effective solution for servicing user groups, manipulating large volumes of content, and facilitating communications between various institutional and public entities. This paper gives an holistic perspective albeit in a short form.
Good to great: lessons for managers
Authors: Filbeck Greg , Gorman Raymond , Parente Diane , Zhao Xin 
Published: November 2010

PurposeJim Collins' Good to Great is but one of many popular press books on management. In his book, Collins discusses the keys to success for today's corporations. Many managers flocked to bookstores to discover what they might be missing in making their organization great. This paper aims to use methodologies more commonly found in the finance literature to validate the results of Collins' study.Design/methodology/approachThis paper uses methodologies more commonly found in finance literature (e.g. event study methodology, Fama‐French three‐factor model with momentum, buy‐and‐hold abnormal returns) to validate the results of Collins' study.FindingsThe results show that the Good to Great firms had unexceptional performance when compared to other benchmark lists of firms, on an ex‐ante or ex‐post basis.Practical implicationsFrom a management perspective, the advice that one might obtain from Good to Great should be carefully examined by managers before they implement it, only to find that great is not really so great.Originality/valueThe paper is original in its methodological design and is valuable to managers who are seeking advice for opportunities that enhance shareholder wealth.
Verification of a building defect classification system for housing
Authors: Georgiou Jim 
Published: November 2010

PurposeThis paper seeks to verify and validate a building defect classification system that has been previously developed and presented in Structural Survey. In doing so, the paper also seeks to address the following question: “Can Government regulatory control improve the quality of house construction?”Design/methodology/approachArchicentre House Inspection Reports were used.FindingsThe houses built under the HCGA (1988‐1996) from a previous study recorded an average of 2.29 defects per house. The 100‐house sample constructed under the DBCTA (1996 onwards) recorded 536 defects, equating to an average of 5.36 defects per house. This finding suggests that the quality of housing has dropped since the two Acts of Parliament were enacted. There also appears to be a significant increase in the number of consumers requesting inspections by industry professionals while construction is still in progress and before handover is achieved. This, coupled with the substantial increase in the number of defects per house, would suggest that the new Act has not had the desired impact.Originality/valueThe research is the first of its kind to examine the effectiveness of Government regulatory control of quality of housing that is constructed. Using the defect classification system, governments can examine the effectiveness of their domestic building policies.
Condition survey objectivity and philosophy driven masonry repair
Authors: Forster Alan Mark , Douglas James 
Published: November 2010

PurposeThe assessment of a deteriorating masonry structure should lead to an objective evaluation of condition. This process is, however, inevitably subjective owing to human interpretation. The condition of the substrate and the required repairs cannot be guaranteed and may vary from building inspector to inspector. For conservation works the determination of repairs is a function of condition but also directly relates to the underpinning framework of building conservation philosophy. These are also fundamentally subjective. The combination of both condition survey subjectivity and building conservation philosophy's nebulous nature creates the potential for project aesthetic and technical divergence. This paper aims to examine this issue.Design/methodology/approachThe paper presents a literature review and hypothetical case studies.FindingsIt has been shown by various researchers that a visual survey is subjective and is therefore prone to differences in reporting. In addition, the application of building conservation philosophy is seen through the perspective of the professional specifying the repairs. The combination of these two factors leads to the potential for significant project outcomes.Originality/valueSubjectivity of evaluation of condition for traditional masonry structures has been little studied by academics and practitioners alike, and it is generally assumed that these yield objective, rational data. This is not necessarily the case. The application of building conservation philosophy to determine repair strategies is also a subjective process. The combination of both may lead to significant project divergence. These combined factors have never previously been discussed.
Logistical constraints negating the successful completion of live city‐centre building refurbishment projects
Authors: Kangwa Joseph , Olubodun Femi , Nelson Margaret‐Mary 
Published: November 2010

PurposeThis study undertakes to examine the perceived barriers to effective management of live city‐centre building refurbishment projects in the UK. Currently a school of thought posits that refurbishment projects are more unpredictable than new builds. The aim of the study is to identify how, against myriad logistical constraints of city‐centre refurbishment projects, managers endeavour to complete their projects on time.Design/methodology/approachA total of 38 project managers responsible for large and medium‐scale city‐centre refurbishment projects in Manchester, Preston, Liverpool, Leeds, Sheffield and Nottingham were targeted as participants for the study. The projects were selected on the basis of location. Only live and active projects within a busy shopping centre of a city were targeted.FindingsThe study identified, using SPSS and non‐parametric statistical techniques, that the chance of success of planning for live city‐centre projects (LCCP) is impacted by economics, micro traffic flow, the experience of project managers, the share scale of the building form, the availability of specialist refurbishment trades, and how the project itself is linked to the feeder routes to and from the main active shopping areas (MASA). The study concludes that auxiliary skills remain critical to successful project completion; among these is the relationship between local authority agencies and the project team.Originality/valueThe study is unique as it seeks to identify which refurbishment dimensions and challenges are relevant and exclusive to live city‐centre refurbishment projects.
The cross‐cultural appropriateness of survey‐based value(s) research
Authors: Watkins Leah 
Published: November 2010

PurposeCross‐cultural research in marketing has been dominated by survey‐based quantitative approaches; however, the assumption of prior validity required for the adoption of the survey approach to values in cross‐cultural research has yet to be established. This paper aims to review the literature and outlines the problems of the survey‐based approach to cross‐cultural values research. These criticisms relate both to the choice of the method and its execution. The paper outlines the multiplicative effects of these problems, that threaten the validity of the survey methodology in this context, and suggests a methodological alternative.Design/methodology/approachThis paper reviews and synthesises the relevant literature on conceptual and methodological issues pertinent to the survey approach to values research in a cross‐cultural context.FindingsA review of the literature suggests numerous methodological problems that threaten the validity and reliability of the survey approach to cross‐cultural values research. This review exposes a methodological gap that can be filled by a qualitative approach to the study of values in cross‐cultural research. In particular, the paper advocates means‐end methodology as offering significant strengths and addressing several of the weaknesses of the survey‐based approach to cross‐cultural values research.Originality/valueThe paper synthesises the literature on methodological issues in cross‐cultural values research, bringing together disparate criticisms which reveal the range of unresolved problems with the empirical, survey‐based approach to cross‐cultural values research; the paper also offers a suggestion for an alternative methodological approach. The means‐end approach is increasingly being used in various research areas; this paper highlights its appropriateness in a cross‐cultural context, as an alternative to predefined and culturally determined measures that limit our understanding of cross‐cultural values. Means‐end addresses many of the specific weaknesses of the survey method identified in the literature review. This discussion of methodological issues has implications for the field of cross‐cultural research more generally and suggests a critical re‐assessment of cross‐cultural methods is needed.
An experimental investigation of the role of face in service failure and recovery encounters
Authors: Du Jiangang , Fan Xiucheng , Feng Tianjun 
Published: November 2010

PurposeThe concept of face has been deeply embedded in Chinese culture. This paper aims to examine the role of face in service failure and recovery encounters, and to explore the factors that influence customer emotions, recovery satisfaction and behavioral intention based on a proposed conceptual model.Design/methodology/approachThe paper uses a scenario role‐play‐based experimental design to examine the proposed conceptual model in service failure and recovery encounters.FindingsThe results show that face plays an important role in service failure and recovery encounters. Specifically, it is found that the utilitarian recovery and symbolic recovery customers receive in the service recovery encounter can both influence customer face restoration, which in turn affects customer emotions, and behavioral intention on service recovery. Customer emotions are significantly correlated to customer recovery satisfaction.Practical implicationsThe practical implications of this study are mainly two‐fold. First, service providers should pay attention to customers' perceptions of face during service encounters. They should also train their employees to treat all customers with utmost sincerity, which will help to enhance the positive emotional experience of customers. Second, the recovery offered by service providers should not be limited to utilitarian recovery. It has to take into account symbolic recovery as well.Originality/valueThis paper investigates the role of face in service recovery encounters and suggests that face significantly influences customer emotions and behavioral intention on service recovery, and customer emotions in turn significantly affect customer recovery satisfaction

Authors: Liu ShiXiong , Lu YanXiong , Liang QiuPing , Wei ErYue 
Published: November 2010

PurposeThe purpose of this paper is to report the results of a study undertaken to investigate the effect of Chinese traditional cultural values on the gift‐giving behavior of consumers in the People's Republic of China (PRC) and to check the moderating effects of Chinese traditional cultural values on a consumer's purchase intention and self‐consistency.Design/methodology/approachUsing a survey among a large sample of people in four cities, gift‐giving behavior, purchase intention and self‐consistency of the consumer in purchasing decisions were measured by the scale. The Chinese traditional cultural values include Confucianism, Buddhism and Taoism. Factor analysis and hierarchical regression analysis were used to analyze the data.FindingsResults indicates that Chinese traditional cultural values have significant moderating effects on gift‐buying intention accords with gift‐giver's image and purchase intention accords with gift‐receiver's image. Consumers with higher value orientation are more careful about consistency between gifts with self‐image and receiver's image.Research limitations/implicationsResearch results should be interpreted with caution as the study was limited to several major cities in the PRC. Also the questionnaire has neglected some people who did not fully understand the questions.Practical implicationsThis study points out those Chinese traditional values that play an important role in gift‐buying decisions. Results will provide some professional opinion for some insider engage in gift marketing and add new viewpoints.Originality/valueThe paper develops new scales for measuring constructs such as Chinese traditional cultural values, attitude for gift‐giving and gift‐buying intention.
