Non‐Newtonian boundary layer flow induced by a permeable surface stretched with prescribed skin velocity
Authors: Postelnicu A. , Pop I. 
Published: April 2013

PurposeThe purpose of this paper is to investigate the steady flow of a non‐Newtonian power‐law type fluid over a permeable stretching surface. The surface is stretched with a prescribed skin velocity following a power‐law variation along its length.Design/methodology/approachUsing appropriate similarity variables and boundary layer approximations, the continuity and momentum equations are reduced to an ordinary differential equation subject to appropriate transformed boundary conditions, with three dimensionless parameters: the power‐law index of the non‐Newtonian fluid, suction/injection parameter and the power law index of the skin velocity. These equations are solved numerically by using the fourth‐order Runge‐Kutta integration algorithm coupled with a conventional shooting procedure. Comparisons with closed form analytical solutions obtained for the case of Newtonian fluid by previous authors are also performed.FindingsIt was found that the dimensionless entrainment velocity decreases with the power exponent m, of the prescribed skin velocity, irrespective of the non‐Newtonian fluid nature, for both impermeable and permeable surfaces. Large rates of injection lead to very large values of the skin friction, the effect being more intense for small values of the dimensionless flow index n. At the same rate of the injection/suction, the skin friction S is increased when the surface is stretched linearly than uniformly.Practical implicationsThis type of problem has potential to serve as a prototype for many manufacturing processes such as rolling sheet drawn from a die, cooling and/or drying of paper and textile, manufacturing of polymeric sheets, sheet glass and crystalline materials, etc.Originality/valueA thorough analysis of the hydrodynamics of a stretching surface is performed in the present paper, by combining analytical and numerical means. The topics covered here (Ostwald‐de Waele power‐law fluid + prescribed skin velocity + permeability of the stretching surface) seem to be not reported till now in the literature.
Information needs and seeking behaviours of nurses
Authors: Baro Emmanuel E. , Ebhomeya Loveth 
Published: April 2013

PurposeThe purpose of this paper is to identify the information needs of nurses in two hospitals in Nigeria and the ways in which they went about attempting to meet those needs.Design/methodology/approachThe study is a descriptive survey of nurses at the Federal Medical Center (FMC), Yenagoa, and Niger Delta University Teaching Hospital (NDU‐TH), Okolobiri, in Bayelsa State, Nigeria.FindingsThe main reasons that motivated nurses to search for information were better patient care, improved medication administration, and better job performance. The main types of information needed by the nurses were how to avoid contracting HIV‐AIDS from patients, information about the outbreak of diseases and new discoveries in nursing. They were hampered by their inability to access foreign nursing journals and a lack of awareness of how to use medical databases. This could be due to a lack of funding to subscribe to local and foreign journals, and lack of education and training in the skills of using medical databases.Originality/valueThis type of information may prove useful to decision makers such as unit managers, directors of nursing services, and hospital executives.
The implementation process of alcohol policies in eight Swedish football clubs
Authors: Geidne Susanna , Quennerstedt Mikael , Eriksson Charli 
Published: April 2013

PurposeAlcohol stands in an ambiguous relationship to sports, and there is a common belief that participation in sports prevents alcohol consumption. Although this is not always the case, sports clubs can be important settings for health promoting alcohol policy interventions .The purpose of this paper is to explore the process of implementing alcohol policies in eight football clubs in Sweden and, in particular, how the implementation process is conveyed in the clubs’ alcohol policy projects, the similarities and differences between this case study and Durlak and DuPre's implementation model and the recommendations for successful alcohol policy implementation in relation to the result.Design/methodology/approachIn total, 15 semi‐structured interviews on the subject of sports’ club alcohol policies were conducted with project leaders and board members from eight sports clubs. The interviews were analysed using Durlak and DuPre's model of factors affecting implementation processes.FindingsThe results show that almost all the factors in Durlak and DuPre's model were comprehensively manifested in the football clubs’ alcohol policy projects, although with slightly different significance and emphases.Practical implicationsThe results are discussed in relation to recommendations for successful alcohol policy implementation in sports clubs. Recommendations are presented in six areas: an explicit message; fit; internal policy dissemination; alcohol policy as a part of overall policy; support; and actors.Originality/valueMany sports clubs do an excellent job of implementing alcohol policies successfully and it is imperative to incorporate their “good” practices into research and provide assistance to those whose policies and practice are less developed.
Who suffers pluralistic ignorance of conflict avoidance among Japanese?
Authors: Saito Takashi , Ohbuchi Ken‐ichi 
Published: April 2013

PurposeThe purpose of this study is to examine individual differences in the susceptibility to pluralistic ignorance of avoidance among Japanese by measuring the value of social harmony.Design/methodology/approachTwo studies were conducted to examine the effects of a concern for social harmony on pluralistic ignorance of conflict avoidance among Japanese, hypothesizing that the pluralistic ignorance of avoidance will occur more frequently among those with a low regard for the value of social harmony than those with a high regard.FindingsConsistent with the hypothesis, pluralistic ignorance occurred only among Japanese participants with a low regard for the value of social harmony and not among those who valued it highly.Originality/valueThese findings suggest that those who have a different stance from the cultural value feel a normative pressure by the biased perception of others' behavior due to pluralistic ignorance, which, as a result, works to preserve the predominant cultural value.
Miracle that never was: disaggregated level of inequality in Indonesia
Authors: Zulfan Tadjoeddin Mohammad 
Published: April 2013

PurposeThe paper aims at re‐examining the notion of low and stable income inequality during the high growth period of Indonesia (1970s‐1990s).Design/methodology/approachDifferent approaches are used to reassess the low and stable trend of the overall inequality at the national level such as assets concentration and functional income inequality. Disaggregated inequality at district level is conducted by treating municipalities as growth centres and estimated using the random and fixed effects models as well as the GMM estimation.FindingsAlternative measures of income inequality have indicated that economic inequality in Indonesia was not as low as it was perceived and exhibited an increasing trend during the period associated with the miracle. Furthermore, using the Susenas‐based Gini coefficient, across‐district analysis of inequality indicates the presence of inverted‐U Kuznets curve of income and inequality, which could not be empirically observed when the analysis is based on time series data of aggregate Gini measure at the national level.Originality/valueThe paper challenges the notion of the East Asian economic miracle in the case of Indonesia. It provides some evidence of the Kuznets curve relationship between income and inequality within a country based on cross‐districts exercise.
Fighting corruption in Africa: do existing corruption‐control levels matter?
Authors: Asongu Simplice A. 
Published: April 2013

PurposeAre there different determinants in the fight against corruption across African countries? Why are some countries more effective at battling corruption than others? To assess these concerns this paper aims to examine the determinants of corruption control throughout the conditional distribution of the fight against corruption using panel data from 46 African countries for the period 2002‐2010.Design/methodology/approachThe panel quantile regression technique enables us to investigate if the relationship between corruption control and the exogenous variables differs throughout the distribution of the fight against corruption.FindingsResults could be summarized in the following. Greater economic prosperity leads to less corruption control and the magnitude of the effect is more important in countries where the fight against corruption is high. Regulation quality seems bimodal, with less positive effects in the tails: among the best and least fighters of corruption. There is support for a less negative consequence of population growth in countries that are already taking the fight against corruption seriously in comparison to those that are lax on the issue. Findings on democracy broadly indicate the democratization process increases the fight against corruption with a greater magnitude at higher quantiles: countries that are already taking the fight seriously. The relevance of voice and accountability in the battle against corruption decreases as corruption control is taken more seriously by the powers that be. Good governance dynamics of political stability, government effectiveness and the rule of law gain more importance in the fight against corruption when existing levels of corruption control are already high.Social implicationsThe results of this study suggest that the determinants of corruption control respond differently across the corruption‐control distribution. This implies some current corruption‐control policies may be reconsidered, especially among the most corrupt and least corrupt African nations. As a policy implication, the fight against corruption should not be postponed; doing so will only reduce the effectiveness of policies in the future. The rewards of institutional reforms are more positive in countries that are already seriously engaged in the corruption fight.Originality/valueThis paper contributes to existing literature on the determinants of corruption by focusing on the distribution of the dependent variable (control of corruption). It is likely that good and poor corruption fighters respond differently to factors that influence the fight against corruption. There are subtle institutional differences between corrupt and clean nations that may affect corruption‐control determinants and government efficacy in the fight against corruption.
A‐REIT rights issues
Authors: Dimovski Bill 
Published: April 2013

PurposeThis is the first REIT paper to seek to empirically examine potential influencing factors on the discounts and underwriting fees of Australian REIT rights issues.Design/methodology/approachUsing a methodology similar to Owen and Suchard, and Armitage, a sample of 62 A‐REIT rights issues during 2001‐2009 is analyzed. A variety of potential factors influencing discounts and underwriting fees are explored.FindingsOver A$20 billion was raised by A‐REIT rights issues during 2001‐2009 (this around three times that raised through A‐REIT initial public offerings during the same period). The mean offer price was discounted around 9.5 percent from the current market price and underwriting fees averaged 2.9 percent of gross proceeds raised – both substantially less than for industrial rights issues. The standard deviation of daily returns for the past year appears to influence the percentage discount offered to subscribers. This volatility was particularly noticeable in 2008 and 2009, during the global financial crisis, where new issues were discounted substantially so as to raise equity to repay debt. This historical risk variable appears paramount in determining the discounts to subscribers and fees to underwriters.Practical implicationsA‐REITs seeking to minimize the discounts offered to subscribers and to minimize their underwriting costs with rights issue equity capital raisings must first minimize their share price volatility.Originality/valueThis paper adds to the international costs of capital raising literature of REITs by examining such costs with A‐REIT rights issues and is the first paper to examine factors influencing these costs.
Reversionary freehold valuations: over‐rented cash flows by spreadsheet
Authors: French Nick 
Published: April 2013

PurposeThe majority of investment property is valued at a point after the original letting or agreed market rent (MR) at review. This briefing aims to look at the valuation of “over‐rented” property. That is the term used to describe a property where the current rent passing exceeds the current market rent.Design/methodology/approachThis briefing looks at the valuation of over‐rented property by discounted cash flow and provides an example of setting up a flexible template by spreadsheet.FindingsThe spreadsheet template allows the valuer to value the over‐rented cash flow by modified or full DCF.Practical implicationsThe flexibility of the template allows the user to change the length of the lease, the rent reviews and it calculates the term until the rent passing is exceeded by the estimated market rent.Originality/valueThe technique is not original but the spreadsheet template helps to explain the profile of the cash flows derived from over‐rented properties.
The five key roles of managers: how HR can build engagement that lasts
Authors: Sparrow Jane 
Published: April 2013

PurposeThe purpose of this paper is to show how human resources (HR) can influence sustained engagement by supporting managers to be expert engagers of others.Design/methodology/approachThis article discusses the limitations of organizational level engagement strategies in relation to sustained engagement. It outlines the critical task managers and leaders play in securing meaningful, long‐term engagement, based on the author's personal views, experience and analysis of effective engagement strategies. The article outlines five key roles that managers need to be proficient in if they are to influence high performance in others. The effectiveness of the roles is supported with the author's observations of managers, leaders and HR practitioners who all excel as engagers.FindingsWhilst organizational level engagement strategies play a key role in building understanding and awareness for employees, this is rarely enough to secure deeper and more meaningful levels of engagement that endure. Managers are the missing link in building cultures of performance but they cannot do so alone. HR must support their managers and leaders as engagers with the practical skills and personal development they need to ensure they can deliver.Originality/valueThe article refers to the type of support and counsel managers require of HR to help them fulfill their five roles as engagers. Some practical steps are given within the article for this specific purpose.
Dissecting home regionalization: how large does the region loom?
Authors: Sammartino Andre , Osegowitsch Thomas 
Published: April 2013

PurposeThe paper aims to motivate more rigorous theoretical and empirical specification of the home regionalization phenomenon, in particular the dynamics of shifting advantage over time within a multinational enterprise. It aims to improve dialogue among regionalization researchers.Design/methodology/approachContrasting the economizing and behavioral perspectives on internationalization, the paper presents five different archetypes of the home‐regionalization phenomenon. These archetypes are predicated on strategic management stylizations of competitive advantage.FindingsThe paper demonstrates that the notion of home regionalization as a dominant and superior model for firm internationalization remains a promising yet under‐explained and inconsistently articulated thesis. By introducing and exploring the archetypes, it shows the diversity of home‐regionalization theses, and the prospect that multiple forms of regionalization may be at play for different firms, industries and locations.Originality/valueThe paper presents the full complement of archetypes of the home‐regionalization phenomenon and explores their corresponding assumptions. These explorations open up new empirical and theoretical research avenues for distinguishing any genuine region effects.
Evaluation of production control strategies for negligible‐setup, multi‐product, serial lines with consideration for robustness
Authors: Olaitan Oladipupo A. , Geraghty John 
Published: April 2013

PurposeThe aims of this paper is to investigate simulation‐based optimisation and stochastic dominance testing while employing kanban‐like production control strategies (PCS) operating dedicated and, where applicable, shared kanban card allocation policies in a multi‐product system with negligible set‐up times and with consideration for robustness to uncertainty.Design/methodology/approachDiscrete event simulation and a genetic algorithm were utilised to optimise the control parameters for dedicated kanban control strategy (KCS), CONWIP and base stock control strategy (BSCS), extended kanban control strategy (EKCS) and generalised kanban control strategy (GKCS) as well as the shared versions of EKCS and GKCS. All‐pairwise comparisons and a ranking and selection technique were employed to compare the performances of the strategies and select the best strategy without consideration of robustness to uncertainty. A latin hypercube sampling experimental design and stochastic dominance testing were utilised to determine the preferred strategy when robustness to uncertainty is considered.FindingsThe findings of this work show that shared GKCS outperforms other strategies when robustness is not considered. However, when robustness of the strategies to uncertainty in the production environment is considered, the results of our research show that the dedicated EKCS is preferred. The effect of system bottleneck location on the inventory accumulation behaviour of different strategies is reported and this was also observed to have a relationship to the nature of a PCS's kanban information transmission.Practical implicationsThe findings of this study are directly relevant to industry where increasing market pressures for product diversity require operating multi‐product production lines with negligible set‐up times. The optimization and robustness test approaches employed in this work can be extended to the analysis of more complicated system configurations and higher number of product types.Originality/valueThis work involves further investigation into the performance of multi‐product kanban‐like PCS by examining their robustness to common sources of uncertainties after they have been initially optimized for base scenarios. The results of the robustness tests also provide new insights into how dedicated kanban card allocation policies might offer higher flexibility and robustness over shared policies under conditions of uncertainty.
Optimization of robotic assembly sequences using immune based technique
Authors: Biswal B.B. , Deepak B.B. , Rao Y. 
Published: April 2013

PurposeThe purpose of this paper is to develop a new methodology to find out the best robotic assembly sequence amongst feasible robotic sequences.Design/methodology/approachThe feasible robotic assembly sequences were generated based on the assembly constraints and later and artificial immune system (AIS) was implemented to find out the best assembly sequence.FindingsThe paper reveals the best assembly sequence.Originality/valueRobotic assembly has expanded the process capabilities in the manufacturing world because of the fact that it is faster, more efficient, precise and cost‐effective process than any conventional mechanized process. Since a robotic system is a cost‐intensive one it is necessary to find out the correct and optimal sequence with the constraints of the process in mind while dealing with assembled products with large number of parts.
The effects of unbalancing operation time variability on the performance of unreliable lines
Authors: Shaaban Sabry , McNamara Tom , Hudson Sarah 
Published: April 2013

PurposeThe purpose of this paper is to investigate the performance of unpaced unreliable production lines that are deliberately unbalanced in terms of their coefficients of variation (CVs).Design/methodology/approachA series of simulation experiments were carried out for five and eight station lines with mean buffer space set at one, two, four and six units. CVs were allocated in 12 different configurations for each of these lines.FindingsThe results show that the best unbalanced CV patterns in terms of throughput rates or idle times as compared to a balanced line counterpart are those where the steadiest stations are concentrated near the centre of the line. On the other hand, either concentrating the steadier operators towards the centre or close to the end of the line gives best average buffer level results.Practical implicationsThe results provide guidelines for production line managers when designing unpaced unbalanced lines depending on their performance aims.Originality/valueThe investigation of the effects of unbalancing CVs in unreliable lines has not previously been studied and can provide insights into how best to place workstations with differing variability along the line.
Recent research trend of economic‐lot scheduling problems
Authors: Kai Chan Hing , Ho Chung Sai , Lim Ming K. 
Published: April 2013

PurposeThis research note aims to present a summary of research concerning economic‐lot scheduling problem (ELSP).Design/methodology/approachThe paper's approach is to review over 100 selected studies published in the last 15 years (1997‐2012), which are then grouped under different research themes.FindingsFive research themes are identified and insights for future studies are reported at the end of this paper.Research limitations/implicationsThe motivation of preparing this research note is to summarize key research studies in this field since 1997, when the ELSP problems have been verified as NP‐hard.Originality/valueELSP is an important scheduling problem that has been studied since the 1950s. Because of its complexity in delivering a feasible analytical closed form solution, many studies in the last two decades employed heuristic algorithms in order to come up with good and acceptable solutions. As a consequence, the solution approaches are quite diversified. The major contribution of this paper is to provide researchers who are interested in this area with a quick reference guide on the reviewed studies.
