Frictional performance of semimetal brake lining for automobiles
Authors: Yin Yan , Bao Jiusheng , Yang Lei 
Published: February 2012

PurposeThe purpose of this paper is to find the variations of brake lining's frictional performance with braking conditions, and their influence on the braking safety and reliability of automobiles.Design/methodology/approachAs the semimetal brake lining is widely used currently in automobiles, it was selected as the experimental material. By simulating the braking conditions and environment of automobiles, some tribological experiments of the brake lining were investigated on the X‐DM friction tester, when it is paired with the friction disc made of gray cast iron. The influence of braking pressure, sliding velocity and surface temperature on the friction coefficient and its stability coefficient were studied in depth through experiments.FindingsThe friction coefficient decreases gradually with the increasing of braking pressure and sliding velocity when the surface temperature is naturally rising. It rises first then falls with the surface temperature rising and the maximal value appears at nearly 200°C. The stability of friction coefficient decreases obviously when the sliding velocity exceeds 30 m/s, the braking pressure exceeds 1.8 MPa and the surface temperature is over 200°C. Based on the experimental results, the authors consider that it is not reliable to execute an emergency braking only by rising the braking pressure when the automobile is driving with a high velocity. In order to reduce the bad influence of high temperature on frictional performance, some effective actions should be taken for cooling the friction disc. What is more, special attention should be paid to the decreasing of frictional stability during the braking with high velocity, pressure and temperature.Originality/valueThis paper studies the influence of braking conditions on friction coefficient and its stability of the semimetal brake lining for automobiles. It is believed that this research may have some actual guidance for enhancing the braking safety and reliability of automobiles.

Authors: Kang Yuang , Chen Cheng‐Hsien , Chen Yi‐Chich , Chang Chi , Hsiao Shun‐Te 
Published: February 2012

PurposeThe purpose of this paper is to present the identification method of restriction parameter and deformation parameter for membrane‐type restrictors.Design/methodology/approachA worktable mounting on the open‐type hydrostatic bearing is utilized to calibrate recess pressures for regulating outlet pressures of restrictors by changing the load and then both restrictor parameters can be identified from the measurements of the inlet pressure, the outlet pressure, and the flow rate of a restrictor by minimizing the difference between measured and identified flow rates. Furthermore, the influences of supply pressure and restrictor designs on both parameters are also studied.FindingsAn identification method for single‐action membrane‐type (SAM) restrictors is obtained directly from experimental results. The measurements of inlet pressure, outlet pressure, and flow rate of the restrictor are substituted into the combined equations for minimization of error between measured and identified flow rates to be solved for restriction and deformation parameters. The identified results show that both parameters can be described by polynomial functions of supply pressure. Both polynomials are regressed by curve fitting from identified results.Originality/valueThe paper shows how to calibrate inlet and outlet pressures of restrictors for designing a hydrostatic bearing system by changing supply pressure and load applied on worktable for the measurements of both pressure and the flow rate of restrictor.
Quid pro quo? Examining talent management through the lens of psychological contracts
Authors: Höglund Mathias 
Published: February 2012

PurposeThe present paper aims to explore the direct and indirect linkages between HRM practices and human capital within a talent management framework. The study extends previous research on the direct effects of HRM to examine how employee responses to HRM practices mediate the linkage between HRM and human capital.Design/methodology/approachThe paper applies psychological contract theory as a lens to assess employee perceptions of the extent to which talent qualities are rewarded and the effect of such perceptions on employee‐felt obligations to develop skills.FindingsThe results indicate that HRM practices are positively related to employee‐perceived talent inducements and that talent inducements fully mediate the direct relationship between skill‐enhancing HRM and human capital. What is more, psychological contract obligations to develop skills partially mediated the relationship between talent inducements and human capital. These results imply that the differential treatment of employees based on criteria constituting talent can have positive effects on employee motivation and felt obligations to develop skills and apply these in service of the organization.Originality/valueThe presented framework and empirical findings reflect a dynamic view of talent management in which talent is not only a label granted to a static group of employees. Through the lens of the psychological contract, talent management can function as a framework within which to define, communicate and engender the development of qualities considered important for the achievement of present and future organizational goals.
When the bored behave badly (or exceptionally)
Authors: Skowronski Mark 
Published: February 2012

PurposeThe purpose of this paper is to explore the relationship between workplace boredom and voluntary work behavior.Design/methodology/approachThe author integrates multidisciplinary theory and research findings to create a process model to guide researchers and practitioners.FindingsExtant literature on boredom coping and interest self‐regulation suggests that individuals often find ways to increase stimulation when feeling bored. This paper discusses how such interest enhancement strategies have both harmful and helpful effects on organizations.Originality/valueThis paper explores situational characteristics and individual differences that moderate boredom's effects on counterproductive work behavior and organizational citizenship behavior. A model with testable propositions is provided. Understanding how employees cope with boredom may lead to new insights for increasing motivation and productivity.
Jobs and organisations
Authors: Cambré Bart , Kippers Evelien , van Veldhoven Marc , De Witte Hans 
Published: February 2012

PurposeThis paper aims to contribute to the understanding of group level differences in job satisfaction. Specifically, the authors seek to understand the shared variance in job satisfaction at the group level of jobs within organisations, in a particular industrial sector. To explain differences in job satisfaction between groups, the authors examine the role of job characteristics, particularly as these are defined within the job‐demand‐control‐support model.Design/methodology/approachThe paper presents the results of a cross‐sectional self‐report questionnaire study of 2,733 Belgian bank employees working in six specific jobs and four specific organisations. Research hypotheses are tested using multilevel analyses.FindingsThere are substantial and reliable between‐group differences in job satisfaction within the banking sector. These effects are partially explained by job characteristics from the JDCS model at the individual level. At the aggregated level, only decision authority is statistically significant.Research limitations/implicationsThe research is limited to Belgium and to the banking sector. The general research question and findings are nevertheless relevant to other single‐sector studies in Western European countries.Practical implicationsDecision authority is more important for group level job satisfaction than job demands and social support from colleagues and supervisors. Human resources managers are therefore recommended to focus more on structural differences and organisational choices that may affect job design and work systems.Originality/valueThe paper aims to make a contribution to the understanding of group level job satisfaction differences in the context of sector studies.
Portraying fitting values in job advertisements
Authors: De Cooman Rein , Pepermans Roland 
Published: February 2012

PurposeThis paper aims to use the signaling theory and the person‐organization fit framework as a rationale to study value‐related information prospective applicants receive from employers through the communication in job ads.Design/methodology/approachThe authors analyzed the content of 1,768 job advertisements published in two national and two regional Dutch‐speaking magazines in Belgium. Four independent judges coded all information in the offer section and categorized it into five content categories adopted from Lyons and colleagues. Since important sectoral distinctions exist in terms of structural‐operational as well as value‐related characteristics, this study examines how profit and nonprofit organizations portray themselves in the offer section of the job advertisements they send out.FindingsGenerally inconsistent with the authors' assumptions, the results show that intrinsic and prestige values are more intensively reported in job ads from the profit sector, whereas altruistic and extrinsic values are brought up more in job ads from the nonprofit sector. However, because nonprofit organizations print smaller, often non‐colored ads in the national language, additional analyses controlling for these factors confirmed only one of the sectoral differences. Nonprofit organizations seem to compensate for values that are obvious in their sector (i.e. altruistic and intrinsic) by more intensively emphasizing extrinsic values (e.g. insurance and fringe benefits) compared to profit organizations.Originality/valueOnly part of the information provided in the earliest phase of the recruitment process reflects the values one would expect based on organizational theory and empirical evidence. This, obviously, engenders an important threat to the establishment of person‐organization fit.
Global self‐initiated corporate expatriate careers: a new era in international assignments?
Authors: Altman Yochanan , Baruch Yehuda 
Published: February 2012

PurposeWithin the current discourse on contemporary careers and the context of international assignments, this paper seeks to conduct a study of a large European MNC, with the aim of theory development on expatriation/repatriation.Design/methodology/approachA qualitative study, based on semi‐structured interviews in a major financial institution.FindingsMotivation to expatriate falls into two distinct categories – company initiated assignments; and self‐initiated, career orientated and/or self‐development focused. The authors propose a two dimensional model to depict the emergence of a new expatriation path alongside the traditional one – differentiating those who respond to an international assignment call within a clearly framed career development path; and those embarking on international assignment as, primarily, a personal growth opportunity. A distinctive sub‐group of corporate self‐initiated expatriates is identified for the first time.Research limitations/implicationsA qualitative study within one company.Practical implicationsThe emergent models could be utilized by HR managers to shape future policies and practices for global assignments.Originality/valueProviding a new model to explicate the relevance of a protean career attitude in a global boundaryless career environment; outlining of new emergent international career trajectories, in particular corporate self‐initiated careers.
Demystifying the data interview
Authors: Carlson Jake 
Published: February 2012

PurposeAs libraries become more involved in curating research data, reference librarians will need to be trained in conducting data interviews with researchers to better understand their data and associated needs. This article seeks to identify and provide definitions for the basic terms and concepts of data curation for librarians to properly frame and carry out a data interview using the Data Curation Profiles (DCP) Toolkit.Design/methodology/approachThe DCP Toolkit is a semi‐structured interview designed to assist librarians in identifying the data curation needs of researchers. The components of the DCP Toolkit were analyzed to determine the base level of knowledge needed for librarians to conduct effective data interviews. Specific concepts, definitions, and examples were sought through a review of articles, case studies, practitioner resources and from the experiences of the Purdue University Libraries.FindingsData curation concepts and terminology are not yet well‐defined and often vary across, or even within fields of study. This research informed the development of a workshop to train librarians in using the DCP Toolkit. The definitions and concepts addressed in the workshop include: data, data set, data lifecycle, data curation, data sharing, and roles for reference librarians.Practical implicationsConducting a data interview can be a daunting task given the complexity of data curation and the lack of shared definitions. Practical tools and training are needed to help librarians develop capacity in data curation.Originality/valueThis article provides practical information for public service librarians to help them conceptualize and conduct a data interview with researchers.
Digital games in academic libraries: a review of games and suggested best practices
Authors: Snyder Broussard Mary J. 
Published: February 2012

PurposeThe purpose of this paper is to provide an overview of available online library games and offer six suggestions for best practices based on the available games.Design/methodology/approachThe paper presents a thorough review of the literature on online games in libraries as well as an analysis of the games freely available online. Further information from some game designers was sought by e‐mail as needed to enhance the published literature.FindingsA total of 17 online library games have been mentioned in the literature, 11 of which are at least partially available online. They vary greatly in type of game, technical sophistication, cost of development, and visual appeal. Some have been successful (designers report being satisfied), some have been less successful, and some have been abandoned before completion. Suggestions for development of future games include keeping it simple; having a plan to use it in class or market to faculty; “gating” key concepts; making it fun; giving feedback; and play testing throughout the development process.Originality/valueWhile previous articles have mentioned three or four online games in libraries, no one has attempted to make a comprehensive overview or to suggest similarities among what has worked well in these projects. Analyzing the key traits of the more successful games will help librarians develop games in the future.
Which platform do our users prefer: website or mobile app?
Authors: Han Rebekah Wong Shun 
Published: February 2012

PurposeAfter being implemented for two years, HKBUtube (the official video streaming site developed by Hong Kong Baptist University Library) has become a popular source of videos for the university. This video site also begins to draw the attention of the community. When more libraries are starting to respond to the demand for mobile service, the HKBU Library decided not to remain aloof. Before committing itself to the provision of an additional platform, the Library carried out a proof of concept to investigate the likelihood of library users watching videos via a mobile app when the web counterpart was available. This paper aims to investigate this issue.Design/methodology/approachThrough building a small‐scale mobile app to showcase and display videos, this paper studies the use of the app and the popularity of watching videos via smartphones. To yield a more accurate result, a web counterpart was also developed for comparison of usage.FindingsThe data suggest that the usage between the app and website version was about the same. This study also demonstrates the power of Apple's marketing support, the large group of international users, and the effect of broadband speeds.Originality/valueUsage data presented in this paper support the importance of the provision of mobile video collections. This paper also offers practical information that can assist academic libraries in justifying and developing mobile services, in particular mobile media collections.
University of Central Florida's Campus Connections Program
Authors: Mendelsohn Hal 
Published: February 2012

PurposeThe Campus Connections Program can help provide other universities with a better method to reach out to students so they can learn what resources are available to them on their university campus. This paper aims to examine how it does this.Design/methodology/approachAn investigation was performed to find out what services were on the University of Central Florida's campus. Determining that many of the necessary resources were not being promoted to the students, the Campus Connections Program was developed. A review of relevant literature highlighted the point that partnerships/working relationships are important to perform successful outreach to those you wish to contact.FindingsThrough a survey instrument, it was concluded that a better way of reaching out to students was necessary. There are other outlets used to promote an organization's services, the difference shows that the Campus Connections Program provided a better forum for the exchange of information.Research limitations/implicationsA survey of nine questions was administered to representatives who participated in the Campus Connections Program. The survey sought to determine if the established method of reaching out to students was useful.Originality/valueStudent orientations are the normal route groups take to meet students and discuss their services. Providing the time and location within the library for those same groups to meet the students individually, is what makes the Campus Connections Program unique.

Published: February 2012

PurposeThe aim of this viewpoint is to highlight the importance of best practice when hiring external consultancy.Design/methodology/approachReductions in spend by both public and private sector buyers is putting pressure on the consulting industry. Growing competition is leading consultancies known for their focus on strategic consulting to move into the implementation space and other some firms are broadening their areas of operation. With more consultancy firms chasing fewer contracts, it has never been more important for buyers to ensure rigor and good practice when engaging consultancies in order to select the best consultants for the issue at hand.FindingsThis guide documents some of the key best‐practice behaviors and processes for buyers of consultancy.Practical implicationsCompanies can ensure they hire the best consultants for their needs.Originality/valueThe article provides sound practical advice on the need for hiring consultants.
Interview with Hal Gregersen, author of The Innovator's DNA
Authors: by William Strange Interview 
Published: February 2012

PurposeThe purpose of this article is to provide an interview with Hal Gregerson, author of The Innovators DNA.Design/methodology/approachThe paper provides an interview with Hal Gregersen is professor of Leadership at INSEAD, who consults to organizations around the world on innovation, globalization, and transformation and has published extensively in leading academic and business journals. In this interview discusses, The Innovators DNA, a book which emerged from an eight‐year collaborative study in which sought to uncover the origins of innovative – and often disruptive – business ideas. The interview is conducted by an independent interviewer.FindingsThrough the book, which Hal co‐authored with Jeffrey Dyer and Clayton Christensen, it was discovered that there are five skills that innovators traditionally engage in: questioning to provoke the status quo; observing like an anthropologist; networking for ideas not for careers; experimenting; and associational thinking i.e. connecting the unconnected.Originality/valueThe paper highlights that the great innovators of the world not only think differently, but also act differently.
Relationship between managerial values and hiring preferences in the context of the six decades of affirmative action in India
Authors: Saha Sudhir K. 
Published: February 2012

PurposeThe purpose of this paper is to explore the relationship between managerial values and preference for hiring of low caste and female job candidates in the context of the six decades of affirmative action in India.Design/methodology/approachA sample of managers from India filled in a questionnaire indicating their beliefs and values concerning the Indian reservation system, social activism and minority employment. Subjects also made hiring choices in a simulated decision environment.FindingsFindings indicate that managers were marginally in favour of hiring minority candidates and that their values and beliefs concerning minority employment of low caste and female job candidates were mixed.Research limitations/implicationsThe study used self‐reported questionnaires, and the sample size was small. Future studies are recommended to overcome the limitations.Practical implicationsManagers responsible for making hiring decisions should be trained and educated in the need for equity, justice and diversity in the workplace.Originality/valueThis investigation provides empirical evidence linking managerial beliefs and values to hiring preferences of minority job candidates.
