Authors: Huang Chunxia , Cao Qixin , Fu Zhuang , Leng Chuntao 
Published: March 2008

PurposeThis paper sets out to propose a wafer prealigner based on multi‐sensor integration and an effective prealignment method implemented on it.Design/methodology/approachThe wafer and notch eccentricities, on which wafer prealignment is based, are calculated with the peripheral data of the wafer detected by a laser displacement sensor and a transmission laser sensor by means of barycenter acquiring algorithm in a one‐particle system.FindingsThe center and notch prealignment precisions of the system are, respectively, ±1.5 μm and ±30 μrad. Experimentation has proved the validity and effectiveness of the system.Practical implicationsThe wafer prealigner is a subsystem of the lithography in the semiconductor industry. The prealignment algorithm can be implemented in any object with random figures.Originality/valueThe periphery of the wafer is detected by a high‐precision laser displacement sensor and a low‐cost transmission laser sensor instead of a CCD linear sensor used by traditional wafer prealigners, which saves the space occupation of the structure and enhances the systematic prealignment precision. Using barycenter acquiring algorithm in a one‐particle system to calculate the wafer and notch eccentricities is effective and valid.

PurposeThe purpose of this paper is to present an exploratory study of EI in the Lebanese context, investigating empirically variations in EI competency scores (self‐awareness, self‐regulation, self‐motivation, social awareness and social skills) in a sample of 225 Lebanese employees/managers. The study provides preliminary feedback on the possibility of detection of systematic variations in EI levels across demographic variables in the workplace and highlights relevant implications accordingly.Design/methodology/approachA questionnaire‐based measure was developed to capture the basic competencies on a self‐report basis.FindingsThe findings suggest differences in EI scores across different EI competencies for males and females, with males scoring higher on self‐regulation and self‐motivation, and females scoring higher on self‐awareness, empathy and social skills, and that EI levels increase significantly with managerial position.Originality/valueThe value added of this research is to revisit the salience of EI in the workplace and to highlight relevant implications. The research supports the business case for integrating EI valuation into traditional organizational functions (e.g. selection, promotion, and training).

Published: March 2008

PurposeThis study aims to apply a systematic statistical approach, including several plot indexes, to diagnose the goodness of fit of a logistic regression model, and then to detect the outliers and influential observations of the data from experimental data.Design/methodology/approachThe proposed statistical approach is applied to analyze some experimental data on internal solitary wave propagation.FindingsA suitable logistic regression model in which the relationship between the response variable and the explanatory variables is found. The problem of multicollinearity is tested. It was found that certain observations would not have the problem of multicollinearity. The P‐values for both the Pearson and deviance χ2 tests are greater than 0.05. However, the Pearson χ2 value is larger than the degrees of freedom. This finding indicates that although this model fits the data, it has a slight overdispersion. After three outliers and influential observations (cases 11, 27, and 49) are removed from the data, and the remaining observations are refitted the goodness‐of‐fit of the revised model to the data is improved.Practical implicationsA comparison of the four predictive powers: R2, max‐rescaled R2, the Somers' D, and the concordance index c, shows that the revised model has better predictive abilities than the original model.Originality/valueThe goodness‐of‐fit and prediction ability of the revised logistic regression model are more appropriate than those of the original model.
Determination of cable tensions based on frequency differences
Authors: Ren Wei‐Xin , Liu Hao‐Liang , Chen Gang 
Published: March 2008

PurposeOwing to the cable flexibility, it is practically a lot easier to measure the high‐vibration frequencies of the cable than the fundamental vibration frequency. The objective of this study is to present a method to determine the cable tension based on frequency differences so that the effects of cable sag and bending stiffness can be included.Design/methodology/approachThe paper includes theoretical derivation, laboratory study to verify the method and practical application in a real bridge.FindingsIt is suggested to measure the high‐vibration frequencies, and to use the vibration frequency difference to determine the fundamental vibration frequency of the cable and then to estimate the cable tension. The reliability of the method is verified by laboratory tests and the method is then applied to determine cable tensions in a real bridge.Originality/valueThis paper provides theoretical derivations to demonstrate that under certain conditions, the frequency difference of a cable with sag and bending is almost equal to the natural frequency of the same cable when it is taut. This unique characteristic of cable vibration is used to determine the cable tension similar to the fundamental frequency‐based taut‐string formula that is commonly used in practice.

Published: March 2008

PurposeConvergence in the life sciences and health care industries – the combining of two or more of drugs, diagnostics and devices to create an improved health care product – is leading to new opportunities for business growth and product differentiation. This report aims to examine the issues around convergence, including the drivers, risks and regulatory issues.Design/methodology/approachThis report is based on industry and literature reviews and builds on research carried out by Deloitte Research on the life sciences and health care industry.FindingsThe paper finds that technological advances, evolving health care needs and shifting market conditions are creating favourable conditions for convergence. Developing convergent technologies, however, has risks and uncertainties that life sciences companies need to consider along with regulatory issues. Cross‐sector partnerships are becoming more of a necessity and reality for health care firms, who have to be aware of the many operational and ownership issues involved.Practical implicationsMarket pressures and opportunities are motivating life sciences firms of all types and sizes to invest in convergence. Convergent technology is transforming cardiovascular care, orthopedic treatment, tissue wound management and other clinical areas by creating solutions that are less invasive, less painful, more patient‐specific, more convenient and sometimes more affordable. Consequently, players from all sectors are entering the competition for R&D assets, setting up new rivalries and alliances.Originality/valueIn mapping the many factors surrounding convergence in the life sciences industry, this report enables firms to evaluate their own opportunities and priorities. It proposes a framework that companies can use to decide which pathway to convergence is best for them.

Authors: Kirpo M. , Jakovičs A. , Nacke B. , Baake E. 
Published: March 2008

PurposeAims to present recent activities in numerical modeling of turbulent transport processes in induction crucible furnace.Design/methodology/approach3D large eddy simulation (LES) method was applied for fluid flow modeling in a cylindrical container and transport of 30,000 particles was investigated with Lagrangian approach.FindingsParticle accumulation near the side crucible boundary is determined mainly by the ρp/ρ ratio and according to the presented results. Particle settling velocity is of the same order as characteristic melt flow velocity. Particle concentration homogenization time depends on the internal flow regime. Separate particle tracks introduce very intensive mass exchange between the different parts of the melt in the whole volume of the crucible.Originality/valueTransient simulation of particle transport together with LES fluid flow simulation gives the opportunity of accurate prediction of admixture concentartion distribution in the melt.

PurposeTo evaluate assumptions relevance of an analytical heat flow model used in indirect measurement of heat capacity and thermal conductivity by the modulated calorimetry technique.Design/methodology/approachAssumptions are tested by comparing analytical prediction to numerical simulation results.FindingsThis study validates the analytical model for a solid sample.Research limitations/implicationsThis research only focuses on solid samples.Originality/valueThis paper allows a broader study on the relevance of modulated calorimetry on liquid samples.
Effect of PEG number on dielectric properties of paraffin‐based PEG polymers at microwave frequencies
Authors: Yamada Pittini Yoko , Daneshvari Dana , Leparoux Susanne , Vaucher Sébastien , Ritter Axel , Rohr Lukas , Leuenberger Hans 
Published: March 2008

PurposeTo investigate the effect of poly ethylene glycol (PEG) chain length on the dielectric properties of paraffin‐based PEG polymers (H(CH2)n–(OCH2CH2)mOH) from both experimental and analytical approach.Design/methodology/approachDielectric constant studies of paraffin‐based PEG polymers were carried out at temperatures above the melting point. The measurements were carried out at frequencies between 0.4 and 20 GHz. The number of PEG units, m, was varied from 0 to 80 to investigate the effect of the PEG chain length on the dielectric properties of the whole polymer.FindingsWith the existence of a dipole moment on PEG but not on pure paraffin, both the real and imaginary part of the dielectric permittivity become larger with increasing chain length of PEG. PEG 3000 showed the highest dielectric constants in the measured frequency range. The effect of the PEG chain length can be explained well by introducing the fraction of molecular weight of PEG divided by the molecular weight of the whole polymer (we call this fraction “Mw fraction of PEG”). Both, real and imaginary part of the dielectric permittivity exhibit a cubic dependence of the molecular weight fraction, and the loss tangent exhibits a linear dependence. These relationships make it possible to predict the microwave heating of the polymer in function of the PEG chain length, carbon chain length and microwave frequency.Originality/valueFor the dielectric permittivity of paraffin‐based PEG polymers, the effect of the PEG chain length, carbon chain length and applied microwave frequency on the loss tangent was explained well by introducing the molecular weight fraction of PEG.

Authors: Segall Richard S. , Guha Gauri S. , Nonis Sarath A. 
Published: March 2008

PurposeThis paper seeks to present a complete set of graphical and numerical outputs of data mining performed for microarray databases of plant data as described in earlier research by the authors. A brief description of data mining is also presented, as well as a brief background of previous research.Design/methodology/approachThe paper uses applications of data mining using SAS Enterprise Miner Version 4 for plant data from the Osmotic Stress Microarray Information Database (OSMID) that is available on the web for both normalized and log(2) transformed data.FindingsThis paper illustrates that useful information about the effects of environmental stress tolerances (ESTs) on plants can be obtained by using data mining.Research limitations/implicationsUse of SAS Enterprise Miner was very effective for performing data mining of microarray databases with its modules of cluster analysis, decision trees, and descriptive and visual statistics.Practical implicationsThe data used from the OSMID database are considered to be representative of those that could be used for biotech application such as the manufacture of plant‐made‐pharmaceuticals and genetically modified foods.Originality/valueThis paper contributes to the discussion on the use of data mining for microarray databases and specifically for studying the effects of ESTs on plants.
Planning successful partnership in the process of outsourcing
Authors: Kavčič Klemen , Tavčar Mitja I. 
Published: March 2008

PurposeThis paper aims to deal with the dynamic aspect of outsourcing – in the world of business, change is the only constant, nothing is permanent, which also holds true for the relationships in outsourcing. Thus, we should think about the consequences of the termination of such a relationship, which could be effected by both sides. This research is aimed at finding an answer to the question of what outsourcing can bring in the long run.Design/methodology/approachThe research for this paper is based on the collection and analysis of quantitative and qualitative data.FindingsThe research results show that companies are ill‐prepared for the time when the cooperation between the outsourcing and insourcing company ends.Originality/valueThe initial research has proved that outsourcing can bring about increased short‐term, especially financial, gains. But at the same time, the cause of poor quality and difficulties can also be concealed, and the reputation and success of the company can be ruined. Problems may be revealed later and can exceed the short‐term benefits of outsourcing.
Growing spanning trees in plasmodium machines
Authors: Adamatzky Andrew 
Published: March 2008

PurposeThe purpose of this paper is to address the novel issues of executing graph optimization tasks on distributed simple growing biological systems.Design/methodology/approachThe author utilizes biological and physical processes to implement non‐classical, and in principle more powerful, computing devices. The author experimentally verifies his previously discovered techniques on approximating spanning trees during single cell ontogeny. Plasmodium, a vegetative stage of slime moldPhysarum polycephalum, is used as experimental computing substrate to approximate spanning trees. Points of given data set are represented by positions of nutrient sources, then a plasmodium is placed on one of the data points. Plasmodium develops and span all sources of nutrients, connecting them by protoplasmic strands. The protoplasmic strands represent edges of the computed spanning tree.FindingsOffers experimental implementation of plasmodium devices for approximation of spanning tree.Practical implicationsThe techniques, discussed in the paper, can be used in design and development of soft bodied robotic devices, including gel‐based robots, reconfigurable massively robots, and hybrid wet‐hardware robots.Originality/valueDiscusses original ideas on growing spanning trees, and provide innovative experimental implementation.
Contextual leadership development: a South African perspective
Authors: Magner Colleen 
Published: March 2008

PurposeThis paper aims to highlight the importance and impact of leadership education which is contextually relevant. It is based on a case study of an innovative learning programme, Nexus, at a leading business school in South Africa (Gordon Institute of Business Science). South African institutional leaders are under increasing pressure to take on a significant role in guiding the organization in a manner that is in tune with the political mandate of social transformation.Design/methodology/approachNexus has been operating as a leadership development programme for five years, and various evaluation methods have been employed to assess the success and impact of the programme. This paper therefore has a multi‐phased approach which will look at the different stages of the programme's development, what methods were used, and how participants' perspectives have changed over time.FindingsThe evaluations show that Nexus contributes to an individual's leadership development, in particular, by understanding the broader issues affecting their organisations and society, how to work in diverse environments, and how to build trust across networks.Originality/valueThis paper highlights alternative, mainly out‐of‐classroom, learning methods which have been assessed in a specific case study over a period of four years. This case study has informed leadership development recommendations, which in turn hopes to influence the scope of leadership education in business school institutions.
Optimized pattern grading
Authors: Bye Elizabeth , LaBat Karen , McKinney Ellen , Kim Dong‐Eun 
Published: March 2008

PurposeTo evaluate current apparel industry Misses grading practices in providing good fit and propose grading practices to improve fit.Design/methodology/approachParticipants representing Misses sizes 6‐20 based on ASTM D 5585 were selected. The fit of garments from traditionally graded patterns was assessed. Garments were fit‐to‐shape on participants. Traditionally graded patterns were compared to fit‐to‐shape patterns using quantitative and qualitative visual analysis.FindingsCurrent apparel industry grading practices do not provide good fit for consumers. The greatest variation between the traditionally graded patterns and the fit‐to‐shape patterns occurred between sizes 14 and 16. For size 16 and up, neck and armscye circumferences were too large and bust dart intakes were too small.Research limitations/implicationsThis study was limited to a sheath dress in Misses sizes 6‐20. Future research should assess the fit of garments from traditionally graded patterns for other size ranges.Practical implicationsMultiple fit modes are needed in a range of more than five sizes. The fit model should be at the middle of a sizing group that does not range more than two sizes up or down.Originality/valueThere are few studies on apparel grading that test fit of actual garments on the body. The analysis documents the real growth of the body across the size range and suggests that changes in body measurements and shape determine the fit of a garment. These findings impact future research in apparel and the practices of apparel manufacturers.
Conspicuous consumption among middle age consumers: psychological and brand antecedents
Authors: Shukla Paurav 
Published: March 2008

PurposeThis paper sets out to address the issue of conspicuous consumption among middle age consumers (40‐60), focusing on the psychological and brand antecedents, using the context of automobile buying behaviour. Existing literature does not clearly conceptualise psychological and brand antecedent and their effect on conspicuous consumption due to usage of inconsistent measurement techniques and being largely targeted at the youth segment.Design/methodology/approachTwo scales of measurement (psychological antecedent scale, brand antecedent scale) were employed to measure the impact. The study involved a quantitative research methodology employing a structured questionnaire and quota sampling with a total sample of 302 within the region of the South‐East of the UK.FindingsThe findings suggest that psychological and brand antecedents are of crucial importance among middle‐aged consumers in influencing their conspicuous consumption.Practical implicationsUsing the examples of present communication strategies adopted by conspicuous product marketers, the paper argues how they are missing an opportunity and provides them with a novel way to market their brands, focusing on how consumers associate themselves with these brands.Originality/valueThe paper is the first of its kind to explicitly investigate the impact of brand and psychological antecedents among middle‐aged consumers – one of the most significant segments for conspicuous marketers, yet so far understudied.
A new approach to analysing comovement in European equity markets
Authors: Bhar Ramaprasad , Hamori Shigeyuki 
Published: March 2008

PurposeTo provide an alternative channel of investigation of comovement in four large European equity markets over a sample period of nearly 30 years.Design/methodology/approachThe paper adopts a two stage methodological approach. In the first instance, the interaction between the equity market and the industrial production in each of the countries is analysed in a hidden Markov framework. This helps extract the information on expansion and contraction of the economies over the three decades. In the second stage, the inference on probability of expansion and contraction of the economies is used to measure the level concordance between these probability series. This helps deduce the level of comovement between the equity markets.FindingsAlthough the nature of interaction between the equity market and the industrial production in these countries are different, the overall comovement in the equity markets is well established.Originality/valueThe paper introduces a new style in the process of investigation with respect to comovement in different markets and illustrates that with an example of four large European markets.
