Authors: Salmon S. , Swank M. , Janaki Ram G.D. , Stucker B.E. , Palmer J.A. 
Published: October 2009

PurposeThe purpose of this paper is to investigate the effectiveness of locking or staking of fasteners with epoxy material systems to prevent loss of preload in aerospace environments.Design/methodology/approachA quantitative experimental method is adopted to evaluate epoxy material systems for staking of fastener assemblies subjected to varying dynamic and thermal loads. A statistical design of experiments is employed to probe specific design parameters.FindingsResults show that epoxy application can provide satisfactory fastener locking under a variety of service conditions. It is found that: Epon 828 epoxy provides superior fastener locking compared to 3M Scotch‐Weld Epoxy 2216; epoxy application around screw threads is more effective than application around screw head; and abrading the plate surfaces with 180 grit SiC paper is not an effective or useful surface preparation technique.Research limitations/implicationsThe paper is limited to two commercial epoxy material systems and does not consider important qualitative considerations for industrial use such as cure time and viscosity.Practical implicationsThis and future paper may form the basis of new standards for epoxy staking in the global aerospace industry.Originality/valueThis paper is believed to be one of the very few original experimental studies of fastener staking available in the open literature.

Authors: Patel Vipul , Masood S.H. , Waterman Tim 
Published: October 2009

PurposeThe purpose of this paper is to investigate the static behavior of different type of butt joints for application in a timber sofa furniture frame. In timber sofa structure, butt joints are commonly used between plywood and hardwood members but they are normally designed without any regard to the effect of grain directions of the wood members on the joint strength. The focus of the paper is to look at the effect of grain directions on the wooden member properties and on the strength of the butt joint in order to understand the failure mode to establish a more durable and effective sofa butt joint than the one normally used by the manufacturers.Design/methodology/approachExperiment tests are conducted to determine the mechanical properties of joint members, the maximum load‐carrying capacity of the butt joints, and the types of the failure in the joints in relation to different grain orientations under transverse loading conditions. Plywood and hardwood members are used in construction of the joint tests. Four types of butt joints are constructed with different condition of grain orientation, glue, and screw used in the joint members. The specimens are tested by fixing the plywood member and applying a transverse load to the hardwood member to simulate the conditions in the sofa frame.FindingsResult shows that butt joint with vertical grain orientation and joint with two screws and glue have the maximum load‐carrying capacity compared to the other three cases and compared to the current joint type used in the existing sofa frame design.Originality/valueThe paper is of value to furniture manufacturing industry, in which furniture members and joints are usually over‐designed without regard to grain orientations or applying sound engineering techniques.

Authors: Lowrie Craig , Desmulliez Marc P.Y. , Hoff Lars , Jakob Elle Ole , Fosse Erik 
Published: October 2009

PurposeThe purpose of this paper is to review the design and fabrication of a micro‐accelerometer to be used to measure the heart wall motion of patients who have just undergone coronary artery bypass graft (CABG) surgery. The sensor will provide a means of early warning for the medical staff of associated complications with this surgery occurring.Design/methodology/approachA feasibility paper is carried out with the use of commercially available MEMS three‐axis accelerometers. The sensors are used in animal studies during which the sensor is stitched directly to the surface of a pig's heart. A need for smaller sensors is required and these are designed in‐house and fabricated using a MEMS process. The final dimensions of the sensors are 2.5×3.5×1.4 mm in width, length and height, respectively.FindingsThe results of the feasibility studies demonstrate the viability of this type of sensor for heart wall motion measurement. It is possible to detect abnormalities, which can indicate complications associated with CABG. The sensors presented here are fabricated within the tight overall size specifications deemed necessary for this application.Research limitations/implicationsThis paper demonstrates an application of MEMS for implantable medical sensors.Practical implicationsIn the UK, approximately 300,000 people have a heart attack each year. One of the most common surgeries that is used to treat this is CABG. This sensor is to be used by the medical staff in post‐surgery to provide “real‐time” monitoring of the heart and give early warning of regional cardiac ischemia which can save lives and reduce hospital waiting times and costs.Originality/valueThis paper demonstrates an original way of measuring heart wall motion. Results from the feasibility studies have proven that this can provide an invaluable way of providing early warning of complications after heart surgery.
Productionisation issues for commercialisation of microfluidic based devices

Published: October 2009

PurposeMicrofluidic or “lab‐on‐a‐chip” technology is seen as a key enabler in the rapidly expanding market for medical point‐of‐care and other kinds of portable diagnostic device. The purpose of this paper is to discuss two proposed packaging processes for large‐scale manufacture of microfluidic systems.Design/methodology/approachIn the first packaging process, polymer overmoulding of a microfluidic chip is used to form a fluidic manifold integrated with the device in a single step. The anticipated advantages of the proposed method of packaging are ease of assembly and low part count. The second process involves the use of low‐frequency induction heating (LFIH) for the sealing of polymer microfluidics. The method requires no chamber, and provides fast and selective heating to the interface to be joined.FindingsInitial work with glass microfluidics demonstrates feasibility for overmoulding through two separate sealing principles. One uses the overmould as a physical support structure and providing sealing using a compliant ferrule. The other relies on adhesion between the material of the overmould and the microfluidic device to provide a seal. As regards LFIH work on selection and structuring of susceptor materials is reported, together with analysis of the dimensions of the heat‐affected zone. Acrylic plates are joined using a thin (<10 μm) nickel susceptor providing a fluid seal that withstands a pressure of 590 kPa.Originality/valueMicrofluidic chips have until now been produced in relatively small numbers. To scale‐up from laboratory systems to the production volumes required for mass markets, packaging methods need to be adapted to mass manufacture.
Ferrite cores as back yoke for enhancing hall sensor sensitivity in caliper tool for pipeline inspection
Authors: Keshwani Rajesh , Bhattacharya Shiben 
Published: October 2009

PurposeThe purpose of this paper is to describe how to improve magnetic pick up sensor for detection of weak magnetic field. A magnetic marker detection system, built using hall sensors is improved by providing ferrite cores as back yoke to obtain benchmarked performance with reduced number of hall sensors in an equipment for pipeline inspection called caliper tool.Design/methodology/approachThe paper opts for an exploratory study by making various configurations of sensors possible under given constraints, analyzing results of each one of them and correcting the configuration.FindingsInstead of using highly sensitive hall sensors, one can increase the sensitivity of sensor by putting simple ferrite core as back yoke in order to detect weak magnetic field.Originality/valueThis paper fulfils the need of detection of weak magnetic field by changing field direction and maximizing field component in direction of sensitive axis of magnetic sensor.
Workaholism among Norwegian journalists: gender differences
Authors: Burke Ronald J. , Berge Matthiesen Stig 
Published: October 2009

PurposeAlthough workaholism in organizations has received considerable popular attention, our understanding of it based on research evidence is limited. This results from the absence of both suitable definitions and measures of the concept. The purpose of this paper is to examine gender differences in three workaholism components, workaholic job behaviors and work and well‐being outcomes among Norwegian journalists.Design/methodology/approachData are collected from 211 journalists (138 males and 68 females) using anonymously completed questionnaires, with a 43 percent response rate.FindingsFemales and males are found to differ on some personal and situational demographic characteristics, and on one of three workaholism components (feeling driven to work, females scoring higher). Females however report higher levels of particular outcomes (e.g. negative affect, exhaustion) and less professional efficacy, likely to be associated with lower levels of satisfaction and well‐being. Females and males score similarly on the experience of flow at work and absenteeism.Research limitationsAll data are collected using self report questionnaires. It is not clear the extent to which these findings would generalize to men and women in other occupations.Originality/valueThis study adds to the small but growing literature on flow and optimal experience in organizations.
Workplace mentoring for indigenous Australians: a case study
Authors: Burgess John , Dyer Sharlene 
Published: October 2009

PurposeThe purpose of this paper is to present a case for the importance of mentoring programs in addressing the disadvantage of minority groups in the workforce. Also, to report on a workplace mentoring program conducted for indigenous Australians at the University of Newcastle, Australia.Design/methodology/approachInterviews with program participants.FindingsIndigenous Australians are marginalised in the Australian workforce. Governments have developed many special labour market programs for indigenous Australians, the majority of which are based on public sector employment. There is potential for more extensive private sector participation in developing workplace programs to support indigenous Australians. Workplace mentoring, especially through indigenous mentors, is important in assisting indigenous employees sustain employment and enhance workforce attachment. The case study demonstrated how culturally appropriate mentoring programs can be successful in attracting, training and placing indigenous Australians into employment.Research limitations/implicationsConfined to a single case study organisation, but the findings are in keeping with North American research on mentoring indigenous workers.Practical implicationsMentoring has a strong role to play in assisting disadvantaged minorities improve labour market outcomes.Originality/valueThere has been no previous research in the Australian context on mentoring indigenous workers.
Creating an “agora” for storytelling as a way of challenging the gendered structures of academia
Authors: Rindfleish Jennifer , Sheridan Alison , Kjeldal Sue‐Ellen 
Published: October 2009

PurposeThe purpose of this paper is to present personal experiences of using storytelling as a “sensemaking” tool, to argue for the benefits of this method as a process of better understanding the gendered academy and the role storytelling can play in effecting change.Design/methodology/approachDrawing on personal experiences of storytelling within workplaces, the paper explores how stories between colleagues can lead to positive change through the co‐construction of new worlds of meaning which are spontaneously revised through interaction.FindingsThe paper demonstrates how storytelling between individuals experiencing inequality makes visible the gendered practices in academic workplaces and can lead to a change in those experiences of the workplace. Also, such stories can be a means for prompting change through negotiation. Theoretically, a triple‐loop learning environment within an organization could provide the agora required for stories about inequality to be heard continually and change to come about through negotiation.Research limitations/implicationsThe paper uses a method that serves as a heuristic device and as such cannot be generalized for all organizational settings. The findings offer a new but partial solution for negotiating gender inequity in academia by suggesting that there must be more storytelling in openly public spaces between colleagues to challenge and negotiate the gendered organizational cultures of academia.Practical implicationsThe application of the method of triple‐loop learning in academic organizational settings can assist in challenging and changing gender inequity through the consistent use of narratives.Originality/valueThe paper is unique in that it argues for the value of a self‐reflexive narrative form of method which favours stories being shared in public spaces – the agora – as a way of addressing gender inequity within complex, male dominated professions such as academia.
Earnings attainment of immigrants in the USA: the effects of race, gender, and place of birth
Authors: Moore Ami R. , Amey Foster , Bessa Yawo 
Published: October 2009

PurposeThe purpose of this paper is to examine the effect of race, gender, and region of birth by assessing the earnings of blacks and whites from Africa, blacks from the Americas, whites from Europe and Asians from Asia.Design/methodology/approachUsing data from the 2000 Census of Population and Housing, different income levels were used to see if there were any variations in earnings. Logistic regression analyses were used to estimate the odds of earnings at the various percentiles of the income of white African men, controlling for the human capital resources and other demographic variables.FindingsThe paper finds an unambiguous race effect among male workers. White males from both Africa and Europe have significant advantage over non‐white male workers from Africa, the Americas, and Asia. However, the earnings attainment is more favorable to white African males regardless of income levels. Further, a gender effect is also found in that relative to the earnings of white African‐born males, all the female workers in our study had lower odds at all the earning percentiles regardless of race and region of origin.Originality/valueThis paper helps clarify the issue of gender and stratification as it relates to immigrants in the USA.
The unobtrusive knowledge test: validity and stereotype threats
Authors: Martin Daniel E. , Moore Carol F. , Hedgspeth Carol 
Published: October 2009

PurposeThe purpose of this paper is to validate the unobtrusive knowledge test (UKT) in a minority population, and examine its potential for limiting stereotype threat.Design/methodology/approachStudy One: (convergent validity): UKT and Wonderlic Personnel Test (WPT) scores were correlated for 131 students. Study Two: (stereotype threat) 202 minority students were placed into one of four groups based on whether or not they were given instructions to elicit stereotype threat, and whether they took the Excellence scale of the UKT or the WPT.FindingsCorrelations provided evidence of convergent validity between the Excellence subscale of the UKT and the WPT. The stereotype threat study was inconclusive, with no differences being seen in the threat/non‐threat conditions for the WPT, and higher scores in the threat condition than the non‐threat condition for the UKT.Research limitations/implicationsUnreliability of some scales and low correlations of others with the WPT, lessened the overall UKT's convergent validity.Practical implicationsThe need to develop measures of intelligence not subject to adverse impact is clear, and the results of the current research provide justification for further research establishing the properties of the UKT as a selection tool.Originality/valueThis paper offers new evidence of the usefulness of the UKT as a measure of cognitive ability for minority populations, and raises questions about the impact of stereotype threat on the UKT test.

Authors: Waithanji Ngware Moses , Oketch Moses , Chika Ezeh Alex , Noris Mudege Netsayi 
Published: October 2009

PurposeThe purpose of this paper is to examine household characteristics and schooling decisions in terms of enrollment and type of school in an urban setting in Nairobi.Design/methodology/approachThe paper uses a cross‐sectional data set collected in 2005. The sample comprises 7,475 primary school‐aged children. A probit model was estimated to show what influences decisions at household level.FindingsAnalysis shows that different household and individual attributes motivate different decisions. A considerable proportion (40 per cent) of children from the poorest quintile attends non‐public schools compared to 34 per cent from the richest quintile. The findings reveal that better‐off households are more represented in the free primary education (FPE) programme. The predicted probability of a decision to attend a public school for a primary school‐age child increases as the household wealth increases.Practical implicationsThe paper concludes that poorer households are least attending and may be excluded from free public schools.Originality/valueThe paper demystifies the notion that introduction of FPE in developing countries is a pro‐poor policy.
Gender as a “strategic action”
Authors: Carvalho Teresa , Santiago Rui 
Published: October 2009

PurposeThe purpose of this paper is to explore the way gender may be used as an instrument to avoid New Public Management (NPM) potential processes of deprofessionalisation in nursing.Design/methodology/approachIn total, 83 nurses with managerial duties were interviewed in autonomous and corporate public hospitals in Portugal.FindingsNurses used gender as an argument to legitimate their presence in management, and in this way, to keep their control over the profession. Gender stereotypes were used to legitimate their position in two different ways. Firstly, nurses reproduced and reinforced gendered inequality by supporting their male colleagues careers. Secondly, they valorised their feminine skills sustaining that women were in better position to manage hospitals as an extended role from the private domain.Research limitations/implicationsThe paper uses a sample from only one country and care must be taken when extrapolating conclusions to the wider population.Practical implicationsAcknowledges the way NPM reinforces gender stereotypes and contributes to redefine professionalism.Originality/valueRecognition of the complexity and diversity of gender issues in the organisational context and in the structuration of professional legitimacy.
