A coupled analytical-numerical approach for optimal sizing of power inductors
Authors: Makni Zaatar , Demersseman Richard 
Published: November 2014

Purpose
– The purpose of this paper is to present an optimal sizing methodology. It is applied to a foil-coil powder core power inductor used in new generation inverters designed for hybrid and full-electric vehicles. The methodology includes a preliminary analytical calculation and a numerical optimization aimed at minimizing the component size.

Design/methodology/approach
– Unlike bulk magnetic alloys or ferrites, the magnetic non-linearity of powder materials cannot be neglected in the analytical calculation. This non-linearity requires the use of an iterative calculation to search the set of parameters for which the target inductance value and the minimum volume are simultaneously reached. The numerical optimization process is based on 2D Finite Element (FE) analysis carried out with FEMM software tool and a simplex-type algorithm run in Scilab software. These two freewares are coupled using the scifemm.sci script which is included in the FEMM distribution.

Findings
– The association of analytical and FE approaches provides a relevant and quick sizing methodology. It was successfully applied to size a new power inductor.

Originality/value
– The strong non-linearity of the powder material is correctly taken into account in the analytical model thanks to an iterative calculation process. Thus, the preliminary analytical solution is quite relevant. Consequently, a local FE-based optimization is enough to find the optimal solution close by the analytical one. No global optimization is required. A local optimum is sufficient.
The Government as marketer of innovation
Authors: Na Lim Jay 
Published: November 2014

Purpose– The Government's role in industrial innovation has always been conventionally viewed as a regulator rather than a marketer of industrial progress. By breaking out of the box, this study positioned the Government as a marketer of innovation and construction enterprises as “consumers” of innovation products. The marketing mix concept of 4Ps is applied in this study to tailor marketing strategies for Governments, who aim to stimulate a higher level of innovation performance in the construction industry. The paper aims to discuss these issues.Design/methodology/approach– A survey of 97 construction enterprises in Germany is conducted to examine the innovation performance, strategies and resource utilisation of construction firms.Findings– The findings indicate that there is no one-size-fits-all national marketing strategy in promoting construction innovation. The Government is required to classify marketing strategies according to firm sizes and enterprises’ needs in relation to their national innovation environment to maximise their innovation potential.Practical implications– To illustrate this, marketing strategies according to firm sizes for the Government to stimulate higher innovation performance of German construction enterprises are proposed.Social implications– The main recommendation is for the Government to intensify inter-firm co-operation by employing national institutions as the key promoter in establishing and operating industry-led focus groups and world-class research centres.Originality/value– Acknowledging the role of Government as more than an enabler of construction innovation is required in today's knowledge economy. This study proposes that it may be time for Governments to review their conventional role and adopt a more proactive stance in promoting innovation in the manner that counts to construction enterprises.
Information feedback and bidders’ competitiveness in construction bidding
Authors: Lan Oo Bee , Yean Yng Ling Florence , Soo Alexander 
Published: November 2014

Purpose– Contractors rely on effective pricing methods in order to translate potential business into reality for long-term survival of their firms. This involves effective utilization of bidding feedback information toward winning jobs with high profit potential. The purpose of this paper is to experimentally investigate student (inexperienced) bidders’ competitiveness under full and partial information feedback conditions when the number of competing bidders is large (n=12).Design/methodology/approach– This paper adopted an experimental research design. The design used between-subjects variation and involved information feedback as the treatment variable with 120 students who enrolled in a cost-estimating course participated in the experiment.Findings– The result shows that the variations in bids over time for both levels of information feedback are statistically significant. It is found that bidders with full bidding feedback information are more competitive than those with partial bidding feedback information. The bid-spread analysis and the identified effect of these two information feedback conditions on awarded contract sum, provide some further evidence that full information feedback condition would lead to lower average bids in construction bidding.Practical implications– The implication of the findings for construction clients is that they should provide as much bidding feedback information as possible so that the bid prices will be competitive.Originality/value– Given the ambiguity inherent in field data, this paper provides strong justification of using experimental research design in advancing the understanding of construction pricing under different information feedback conditions. In addition, it demonstrated the suitability of using student subjects in similar experiments in the context of construction bidding.
Anandam's woodstove technology
Authors: Saxena Stuti 
Published: November 2014

Subject area
Financial management, marketing management and entrepreneurship.

Study level/applicability
The case is suitable for undergraduate students.

Case overview
The case is based on the ingenuity of the chief protagonist of the case study, Anandam. Anandam had conceived a novel idea of using coconut shells and other biomass material as the fuel for running a woodstove. The case study has its settings in Kerala (India). A tentative business plan is being proposed through the case study, where the market analysis has been done, underscoring the product positioning, market segmentation, pricing and other relevant parameters. Further, the case also lays emphasis on the support provided by a local non-governmental organization, as an initial hand-holding measure.

Expected learning outcomes
The case study has been written for the purpose of students' appreciating the nuances of new technology/product launch in the market, given the existing competitors. This would help in understanding the 4 Ps better, and, raising a good platform for discussion in the classroom. A financial analysis aspect is also given, which would help students to draw an inter-disciplinary perspective vis-à-vis the case. The case may be extrapolated to other start-up ventures by entrepreneurs.

Authors: Andersen Poul Houman 
Published: November 2014

Subject area
Development of business models, base of the pyramid (BoP) markets.

Study level/applicability
This study can be used at Bachelor as well as on Master's level courses to reflect activities and practices within corporate sustainability, base of the pyramid and international expansion of MNEs.

Case overview
This is a case study of Grundfos LIFELINK's development process, relating to the successful development of a business model for serving base of the pyramid (BoP) markets for potable water. Grundfos LIFELINK is a turnkey water solution that encompasses a solar-driven pump facility, a GPS-based monitoring system, and charges based on digital payments of water credits. Together, they represent the business model of Grundfos LIFELINK. At the same time the modules represent a business architecture that can be mixed and matched to match the skills and ensure the adaptive involvement of local partners in BoP markets. Since its cautious start in 2009, Grundfos has successfully expanded its operations to 30 villages in Kenya and LIFELINK systems will operate in 70 villages in Kenya within the next two years.

Expected learning outcomes
In an international business/international management context, especially the first and the last part of the case could be used as a showcase of the current transformation efforts multinational companies (MNCs) in the developed world are pursuing. Pressured by the cost advantages of Dragon multinationals from Asia, India and Brazil, MNCs search for new ways to provide value and at the same time utilize their existing knowledge. The Grundfos LIFELINK case shows some of the important consequences and challenges that multinational organizations are facing, once such business models needs to be integrated in the current MNC activities.

Autonomous leadership and a centralised school system
Authors: Brauckmann Stefan , Schwarz Alexandra 
Published: November 2014

Purpose– Although policy makers strengthen the necessity of “deregulation”, discussions about deregulation vs regulation in Europe still seem to be characterized by a lack of sophistication and require a more differentiated picture of specific forms of deregulation. As a consequence, the analysis of new educational governance approaches should consider the local actor's interpretation of new roles and new responsibilities. Relating actions and reactions of school leaders to their formal environment should lead to more contextual patterns of responsiveness. The paper aims to discuss these issues.Design/methodology/approach– The authors investigate, based on a survey among Cypriot school leaders, whether school autonomy needs deregulation, or regulation towards autonomy, respectively. At the time of research the school system of Cyprus could be characterized as a “centralized” system and hence represented a suitable field of study. Using a factor model followed by a cluster analysis the paper explores the school leaders’ profiles of operative and perceived autonomy in different fields of governance issues and identify different types of leadership.Findings– The authors find that the autonomy school leaders experience is not necessarily related to a “defined” degree of autonomy which is prescribed by educational law and driven by concepts of new public management. Their “perceived” autonomy is also due to factors which can be located at a rather individual level.Originality/value– The findings provide insight into principals’ motives to adopt certain styles of leading schools, quite independently from new measures of educational governance. The authors conclude that greater emphasis on systematic support programmes may prepare school principals for gains of autonomy as well as for potential sources of conflict.
Leadership for school success: lessons from effective principals
Authors: Garza, Jr Encarnacion , Drysdale Lawrie , Gurr David , Jacobson Stephen , Merchant Betty 
Published: November 2014

Purpose– The purpose of this paper is to examine four case studies from the International Successful School Principalship Project to explore and highlight how the role of the principal is critically important to sustaining school success. Implications for improving the preparation of aspiring and practicing school leaders are discussed.Design/methodology/approach– Data were collected using multiple sources, including documents and interviews with a variety of people including the principal, other school leaders, teachers, school council/board members, parents and students. Each case study was analyzed to understand how the principal and other leadership contributed to school success.Findings– There were several core dimensions of the principals’ leadership that led to sustained school success. Principals clearly articulated views on education and helped their schools set appropriate directions. They were all concerned with the professional development of teachers to build capacity and teacher leadership. All principals were instructional leaders who influenced teaching and learning and were committed to making a difference. They exhibited other qualities such as resilience and their motivation to sustain their efforts over time. Another important dimension was building community. These principals reached out to their communities. They clearly understood that they could not succeed in isolation.Originality/value– The notion of sustainability in education remains ambiguous and this paper provides some empirical evidence of how successful school principals maintain school success over an extended period. Importantly, it considers how aspirant and practicing principals can be developed and supported in their efforts to lead and sustain successful schools.
Labour market flexibility and spatial mobility
Authors: Eamets Raul , Jaakson Krista 
Published: November 2014

Purpose– Recent economic recession has highlighted the role of labour market flexibility as a key factor of competitiveness of a country. Despite the fact that labour mobility can essentially be seen as part of labour market flexibility, there is notable research gap concerning spatial mobility and other facets of labour market flexibility. The purpose of this special issue is to fill these gaps.Design/methodology/approach –The papers in the special issue represent various quantitative methods and databases, whereas mainly micro data (workplace, labour force or immigrant surveys, job search portal, etc.) is used. However, the type of labour market flexibility addressed is both micro- and macro-level.Findings– It is demonstrated that labour occupational mobility is determined by the business cycle, numerical flexibility, occupational categories, and sector. Spatial mobility may have counterintuitive effects on individual occupational mobility depending on gender and it is related to various flexibilities in the workplace. It is also suggested that different types of flexibilities on a firm level are interdependent of each other.Originality/value– The special issue adds to the labour market related knowledge by integrating labour market flexibility and mobility. Individually, both phenomena have been studied before, but not much research is devoted to their inter-linkages. The special issue also contributes by examining labour market flexibility and spatial mobility in the context of different countries, economic cycles, and institutional settings.
A thematic analysis of how prisoners overcome suicidality
Authors: Reading Lucy , Bowen Erica 
Published: November 2014

Purpose
– The purpose of this paper is to explore the perceptions, beliefs and abilities that support adult male prisoners in overcoming suicidality.

Design/methodology/approach
– Semi-structured interviews were conducted with eight male life sentenced prisoners in a Category B prison. Thematic analysis was used to analyse the data and interpret how prisoners have overcome suicidality.

Findings
– Five overarching themes were identified; sense of self, presence of meaning, connectedness, shift of perspective and re-establishing control. The themes were closely interconnected and revealed novel insights into the variables that supported prisoners to overcome suicidality.

Research limitations/implications
– The themes were drawn from a specific prisoner population, which may not be representative of the wider prison population. Additionally, the sole focus on suicidality may be an oversimplification of self-destructive behaviours and could have affected the factors identified.

Practical implications
– The results highlight the need to refine suicide prevention strategies in prisons; in the assessment of suicide risk, the improvement of supportive regimes and the development of psychological interventions.

Originality/value
– This research is the first to qualitatively examine the factors involved in overcoming suicide in adult male prisoners. The research is of value to researchers and practitioners alike, as it extends previous research in prison populations and suggests avenues for the development of suicide prevention strategies.
Cooking in prison – from crook to cook
Authors: Kjaer Minke Linda 
Published: November 2014

Purpose– The purpose of this paper is to describe and analyse the principle and practice of self-catering system in a Danish prison. Self-catering is a reflection of the Danish correctional principle of normalisation between prison and community life. Unlike some other jurisdiction, issues of control in meal preparation are subordinate to prisoners’ right to choose and prepare their own food.Design/methodology/approach– Findings are derived from 13 months of ethnographic fieldwork in a Danish maximum security prison for men, including in-depth interviews with 68 prisoners.Findings– Overall findings showed that thinking about meals and their preparation is time consuming for prisoners who tend to be positive about the system making connections with their ability to exercise responsibility for making healthily choices. The research concludes that prisoners’ possibility for developing cooking competences during incarceration could support prisoners change in social identity from crook to cook.Originality/value– Food is a fundamental need and the ability to choose what to eat and to prepare one's own food should be a right for all people, including prisoners. This research shows that Danish prisoners are very pleased about the system of self-catering. Most prisoners are concerned about preparing their own meals according to their taste and cultural diversity. If the prison offers the opportunity to train as a chef during imprisonment it could support the prisoner's change in social identity from crook to cook on the outside.
Measuring the welfare of sub-groups subject to premature mortality
Authors: Doessel D.P. , F. Williams Ruth 
Published: November 2014

Purpose– The purpose of this paper is to provide an exposition of the concepts relevant to measuring the economic effect of premature mortality and the conception of how the social loss from premature mortality can be incorporated into social welfare measurement. None of the conventional welfare measures currently pick up this welfare signal.Design/methodology/approach– Various concepts are examined in the conventional and “new” literatures of welfare measurement. Six Venn diagrams show how various concepts “fit together”.Findings– This paper outlines a framework for measuring the economic effect of premature mortality in a conceptually appropriate way. Thus the paper shows how the welfare loss associated with premature mortality can be incorporated into social welfare measurement.Research limitations/implications– Accurate premature mortality measurement is difficult but this data problem hardly limits this exercise. Sensitivity analyses can alleviate this measurement problem.Practical implications– The main practical implication is that empirical applications are feasible. Time series data can be analysed from this conceptual framework to determine whether the problem of the social loss from premature mortality is improving through time, or worsening.Social implications– Knowing the size of the welfare impact of premature mortality is useful not only on policy fronts concerning premature mortality prevention.Originality/value– “New welfare measurement” has not yet been applied to the notion of the social loss from premature mortality.

Benefits of international portfolio diversification
Authors: Jamaledin Mohseni Zonouzi S. , Mansourfar Gholamreza , Bagherzadeh Azar Fateme 
Published: November 2014

Purpose– This paper aims to investigate opportunities of the short- and long-run international portfolio diversification (IPD) benefits by investing in the Middle Eastern oil-producing countries. Over the past decades, IPD has been the integral feature of global capital markets. Several potential benefits like increasing returns and/or reducing risk have made investors to internationalize their portfolios. Solnik’s theory (1974) approved that gains can be achieved through IPD if returns in the different markets are not perfectly correlated. This may attribute to low correlations of equity returns among different economies. In this regards, there would be a large potential of diversification benefits for investors that diversify into new emerging group of economies such as equity markets of the main oil-producing countries. These markets are often segmented and they may ensure a superior return rate for a given risk level.Design/methodology/approach– In most of the previous studies, Pearson’s correlation test is used to analyze the short-run relationship of market prices. However, recent empirical studies indicate that correlations between equity returns vary over the time. To examine the time-varying conditional correlation, this paper used the dynamic conditional correlation (DCC) model to investigate opportunities of the short-run IPD benefits. In addition, for the long-run linkage analysis, the autoregressive distributed lag (ADRL) approach introduced by Pesaranet al.(2001) is applied.Findings– It is found that, the market returns of the sampled countries are not definitely correlated in the short- and long-term. So, international portfolio investors may get the short- and long-term diversification benefits by diversifying their portfolios among the Middle Eastern equity markets, namely, Iran, Bahrain, Qatar, Kuwait, Oman, Saudi Arabia and UAE.Originality/value– This paper departs from earlier studies by focusing on the dynamic characteristics of correlation. Two main issues are pursued in this paper. First, instead of modeling the correlation by methods like Pearson correlation coefficient that consider the constant-correlation assumption, this paper directly uses the DCC model. Second, to empirically estimate the long-run relationship among stock markets in the Middle Eastern oil-producing countries, the ARDL approach is utilized. The ARDL approach is more robust and performs well for small sample sizes than other co-integration techniques.
