An empirical investigation of brand equity: drivers and their consequences
Authors: S. Davcik Nebojsa 
Published: September 2013

Purpose– The author aims to present a model of the brand value drivers, measured by brand equity. The goal of this research is to identify the drivers, and determine how they influence brand equity performance in the researched industry, in order to develop a more effective brand strategy.Design/methodology/approach– The author studied an aggregate dataset for 739 food brands. Six predictors were controlled for (i.e. marketing investments, price, revenue, perceived quality [organic and functional] and brand ownership), while the impact of the brand equity drivers on brand value was estimated. The model was formulated and estimated using a robust OLS procedure. Several data sources have were in this study, such as market-based data from ACNielsen, as well as information and variable constructs using data from the Bureau Van Dijk Electronic Publishing AIDA financial statements database.Findings– Results suggest that marketing investment, price, revenue, brand ownership and perceived quality are highly associated with brand equity, and consequently with a higher brand value in the food industry.Research limitations/implications– This study has only studied one industry (food), one industry segment (enriched-food) and one country (Italy).Originality/value– The majority of marketing studies apply a single research approach and measures. This is the first study of brand equity that combines consumer, financial and marketing approaches. The model contributes to theory and practice in terms of suggesting which business drivers create brand value and what type of brand strategy a firm can apply in order to create brand value.
Hysteresis parameters estimation using a modified harmony search
Authors: dos Santos Coelho Leandro , Cocco Mariani Viviana , de Athayde Costa e Silva Marsil , Jhoe Batistela Nelson , Vianei Leite Jean 
Published: September 2013

Purpose
– The purpose of this paper is to introduce a chaotic harmony search (CHS) approach based on the chaotic Zaslavskii map to parameters identification of Jiles-Atherton vector hysteresis model.

Design/methodology/approach
– In laminated magnetic cores when the magnetic flux rotates in the lamination plane, one observes an increase in the magnetic losses. The magnetization in these regions is very complex needing a vector model to analyze and predict its behavior. The vector Jiles-Atherton hysteresis model can be employed in rotational flux modeling. The vector Jiles-Atherton model needs a set of five parameters for each space direction taken into account. In this context, a significant amount of research has already been undertaken to investigate the application of metaheuristics in solving difficult engineering optimization problems. Harmony search (HS) is a derivative-free real parameter optimization metaheuristic algorithm, and it draws inspiration from the musical improvisation process of searching for a perfect state of harmony. In this paper, a CHS approach based on the chaotic Zaslavskii map is proposed and evaluated.

Findings
– The proposed CHS presents an efficient strategy to improve the search performance in preventing premature convergence to local minima when compared with the classical HS algorithm. Numerical comparisons with results using classical HS, genetic algorithms (GAs), particle swarm optimization (PSO), and evolution strategies (ES) demonstrated that the performance of the CHS is promising in parameters identification of Jiles-Atherton vector hysteresis model.

Originality/value
– This paper presents an efficient CHS approach applied to parameters identification of Jiles-Atherton vector hysteresis model.
Elimination of common mode voltage using phase shifted dual source matrix converter with improved modulation index
Authors: Mahadevan Senthilkumaran , Raju Siddharth , Muthu Ranganath 
Published: September 2013

Purpose
– The high-frequency common-mode voltage introduced by power converters, using conventional modulation techniques, results in common-mode current that has the potential to cause physical damage to the shaft and bearings of electric drives as well as unwanted tripping of ground fault relays in motor drives and electrical networks. The paper aims to provide a complete elimination of common mode voltage using a matrix converter (MC) with a new modulation strategy that reduces the size of the power converter system considerably. Further, a new MC topology is proposed to eliminate the common mode voltage with improved voltage transfer ratio (VTR).

Design/methodology/approach
– The direct MC topology is selected, as it is the only converter topology that has the potential to eliminate common mode voltage in direct AC to AC systems. Using the rotating space vector technique, common mode voltage is eliminated but this reduces the VTR of the converter. To improve the VTR, a modified MC topology with a modified rotating space vector strategy is proposed. In addition, for improving the power factor at the input, the input current control strategy is developed.

Findings
– The use of rotating space vector technique eliminates the common mode voltage even under all input abnormalities like unbalance and harmonics. By applying positive and negative rotating space vectors, input power factor control can be achieved. However, the control range is limited from unity power factor to the output power factor. It is observed that in the current controlled technique the modulation index reduces further. It is also found that there is a reduction in switching stresses of individual switches in proposed topology compared to direct MC topology.

Originality/value
– In this paper, a modified rotating space vector technique is applied to the proposed converter topology for elimination of common mode voltage with an increased VTR. The topology can be used for common mode voltage elimination in existing electric drives without the need for modifying the drive system.
A novel approach to analysis and design of bang-bang CDR circuits
Authors: Adrang Habib , Miar-Naimi Hossein 
Published: September 2013

Purpose
– Bang-bang clock and data recovery (BBCDR) circuits are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). The specification of the CDR frequency response is determined by jitter tolerance and jitter transfer. In this paper, jitter transfer and jitter tolerance of the BBCDR are characterized. The paper aims to discuss these issues.

Design/methodology/approach
– The presented method is general enough to be used for designing the BBCDR loop parameters to meet SONET jitter transfer requirements (loop bandwidth and jitter peaking).

Findings
– In this paper, jitter transfer and jitter tolerance of the BBCDR are characterized by formulating the time domain waveforms. As a result, a new equation is presented to obtain angular frequency. Also, the jitter tolerance is expressed in closed form as a function of loop parameters. The validity of the resulted equations is verified through HSPICE simulations using TSMC 0.18-μm CMOS process. Simulation results show that good conformance between analytical equations and simulation results.

Originality/value
– The proposed approach offers two advantages compared to conventional designing methods. First, this approach does not consider any value restriction to the capacitor. Second, a new condition has been presented to guarantee that the value of jitter peaking is approximately zero. The presented method is general enough to be used for designing the BBCDR.
Electromagnetic funneling through a single-negative slab paired with a double-positive transformation slab
Authors: Castaldi Giuseppe , Galdi Vincenzo , Alù Andrea , Engheta Nader 
Published: September 2013

Purpose
– The work is aimed at studying the electromagnetic interaction between a homogeneous, isotropic single-negative (SNG) slab and an inhomogeneous, anisotropic double-positive (DPS) slab.

Design/methodology/approach
– The approach is based on the transformation optics framework, which allows systematic design and modelling of anisotropic, inhomogeneous metamaterials with inherent field-manipulation capabilities.

Findings
– The paper finds that a transformation-optics-based DPS slab can compensate the inherent opaqueness to the electromagnetic radiation of a SNG slab. Here, “compensation” means that the resulting bi-layer may give rise to zero-reflection for a normally-incident plane wave at a given frequency. Such phenomenon is inherently accompanied by (de)funneling effects for collimated-beam illumination, and it turns out to be quite robust to material losses as well as geometrical and constitutive-parameter truncation.

Originality/value
– The results provide further evidence and insight in how SNG-like responses may be emulated (within narrow parametric ranges) by suitably-engineered spatial inhomogeneity and anisotropy in DPS media. Moreover, they also show that resonant transmission phenomena through SNG materials may be engineered via the powerful framework of transformation optics.
Electroporation of bone cancer: numerical evaluation of the electric field in treated tissues
Authors: Bisceglia Bruno , de Terlizzi Francesca , Scaglione Antonio , Francesco Tallarino Nicola 
Published: September 2013

Purpose
– Electrochemotherapy (ECT) is an outstanding technique for treatment of tumor nodules which is currently used for treatment of skin metastases, and now it is being developed for treatment of internal organs such as, bone, liver, etc. In this work the authors' goal was finding a simple and proper needles configuration, allowing electroporation of whole cancer cell membranes, possibly minimizing direct cell death of healthy tissue.

Design/methodology/approach
– This work shows numerical analysis of the ECT of a deep-seated tumor, like in bone tissue of human limb. The tumor is excited by a sequence of square-wave electric pulses (5 kHz), inducing a 1,000 V/cm electric field through a suitable configuration of 30 mm long steel needle electrodes inserted in a part of limb long 20 cm. Treated element is numerically modeled in a very simplified 3D geometry. All materials are assumed as homogeneous, linear and isotropic mediums.

Findings
– Electrochemotherapy is based on the local application of short and intense electric pulses that transiently permeabilizes neoplastic cells membrane, thus allowing cytotoxicity increase of a chemotherapeutic drug, bleomycin, and reducing its dosage. The local field in target tissues depends on geometry and position of electrodes, that have to be placed according cancer shape and size, and excited by electric pulses of opportune amplitude. Current efforts are aimed to test whether electric pulses can be applied to bone through invasive needles without affecting the recovery of osteogenetic activity.

Originality/value
– The results of the simulation study can help to establish the appropriate geometric and electric setup for treatment of bone metastases in clinical ECT trials. This paper reports results from different needles configurations and show that a proper needle positioning allows complete electroporation of the whole tumor

Be successful – be male and masculine? On the influence of gender roles on objective career success
Authors: Alewell Dorothea 
Published: September 2013

Purpose
– The purpose of the paper is to analyse the influence of individual gender role specifications on objective career success (measured by gross yearly income) in the context of different gender job contexts whilst controlling for human capital and working time variables. Typical economic, sociological and psychological variables are combined to improve explanations of the gender wage gap.

Design/methodology/approach
– Starting from Eagly and Karau's role incongruity theory, the paper derives hypotheses on the influence of gender role specification, gender job context and biological sex on gross yearly income. These hypotheses are analysed by logistic regressions with a data set from Germany. The paper presents results of a quantitative empirical survey of employees on wages, gender role-related self-descriptions and human capital variables.

Findings
– The paper results show that even in this highly qualified sample, male biological sex, masculine gender roles and non-female job context have a positive effect on individual income. The results hold true when the paper controls for human capital, working time, professional experience and jobs in the public sector.

Research limitations/implications
– Because of the limited size of the data set and some problems with selectivity, the research results lack generalizability. Researchers are thus encouraged to test the propositions with other data sets.

Practical implications
– The paper includes implications for wage design and for reaching wage equality in firms. An important implication for policy and practice is that under a gender and equal opportunity perspective, ensuring non-discriminating behaviour with regard to women may be only one (albeit an important) element of equal opportunity activities. Equal wage policies should further consider the gender characteristics of the job context, which may influence job-related roles and thus role incongruities. Additionally, individual interpretations of gender roles might have effects on wages. Human resource (HR) managers could support such policies by shaping job descriptions carefully with regard to gender role aspects, by influencing the gender composition of job contexts and by paying attention to the individual development of gender role interpretations in HR development programmes.

Originality/value
– The paper fulfils an identified research need to study simultaneously the influence of human capital variables and gender roles on wages. To the authors' knowledge, this is the first study, which studies the influence of gender roles as defined by Born (1992) on income in a German context of highly qualified individuals while controlling for human capital, working time and professional experience. The existing lack in the literature with regard to empirical analyses on the combined influence of economic, sociological and psychological variables is mitigated.
Nonlinear evaluation of status and signal effects
Authors: Schneck Stefan 
Published: September 2013

Purpose
– The purpose of this paper is to describe whether workers in high positions and workers in low positions think differently about status and possible future career advancement opportunities.

Design/methodology/approach
– The paper uses German panel data to examine the effects of relative standing on individual satisfaction with the job, the propensity to change jobs, and intentions to start-up an enterprise in the near future.

Findings
– The relationship between relative wage positions and job satisfaction is inversely U-shaped. This is interpreted as evidence that low status translates into low utility while employees with high relative standing seem to be more concerned about the lack of future career prospects in paid employment. Workers who gather utility from status and career advancement opportunities simultaneously are more satisfied with their jobs. The paper also shows that lower satisfaction with the job translates into considerations to leave the job.

Practical implications
– The described relationships explain individual determinants of voluntary quits and workforce fluctuations, which are of special interest in debates about possible shortages of skilled labor or tightening labor markets for skilled workers.

Social implications
– Individual comparisons with peers affect individual reasoning.

Originality/value
– The paper aims to enhance the discussion about nonlinear effects in status considerations as well as future career advancement opportunities. The paper shows that workers in very high and very low positions value these important psychological traits differently.
Scenistic performance tools for management and employee development
Authors: Lyons Paul , Paul Bandura Randall 
Published: September 2013

Purpose
– The purposes of this article are to familiarize the reader with scenistic learning tools, provide theory bases for the tools, present details for use of the tools in an organization, and offer details with reference to the efficacy of scenistic learning tools.

Design/methodology/approach
– The approach taken is to provide sufficient information for a practitioner to apply scenistic tools with confidence. The paper provides the background and explicit details for using scenistic tools in practice.

Findings
– The findings demonstrate positive effects of training with scenistic tools. The effects are limited to specific areas.

Practical implications
– Several different instructional and/or training approaches may come under the rubric, scenistic, to include case analyses, use of critical incidents, story board and others. This article offers a complete model of how to create and apply a scenistic approach in an orchestrated manner to achieve positive change in an organization.

Originality/value
– The article demonstrates how managers, training staff, and employees (trainees) work in a partnership to create and apply script-based practice guides and interventions to assist in solving actual organizational issues and problems.
Who owns the gap? (part two): the application of Appreciative Inquiry to evaluation
Authors: Elaine Watson Sally 
Published: September 2013

Purpose
– The aim of the paper is to report on application of Appreciative Inquiry to the evaluation of a management development programme involving 72 managers from an organisation delivering further and higher education. The structure and ethos of Appreciative Inquiry resulted in stories of both individual and collaborative learning and the resultant impact on organisational performance. The evaluation data were compared with the outcomes of a previous appreciative inquiry and the discourse generated by participants indicated a shift to a more collaborative culture.

Design/methodology/approach
– Part one of this article outlined a successful application of Appreciative Inquiry to the diagnosis of individual and organisational development needs involving the collaboration of participating managers. The same managers agreed to be part of a second Appreciative Inquiry, in 2012, to generate evaluation data on the impact of their management development on college performance. Content analysis was used with the qualitative data produced to formulate key themes. Deeper meanings and insights into organisational culture were derived from a later discourse analysis.

Findings
– Evidence of a significant change in cross college collaboration was seen in both the content and discourse of the 2012 Appreciative Inquiry. The impact of this collaboration was demonstrated through stories of strategic thinking, innovative solutions and tangible performance improvement. Impact stories also revealed an interesting discursive shift amongst the management population and indicated a greater sense of personal accountability. Discourse analysis also revealed an emerging realisation that interdependent nature of college business was the source of learning about individual and organisational performance.

Research limitations/implications
– The workshop teams from the second Appreciative Inquiry were not the same configuration as the original diagnostic workshops described in part one of this article. During the management development programme, action learning sets were created with team coaching support. The impact of team coaching on the sustainability of learning became clear during the second Appreciative Inquiry. The teams were more experienced at working collaboratively and their self-management of the process more confident and effective.

Practical implications
– Appreciative Inquiry can be used to diagnose development needs, create an evaluation framework and later conduct an impact evaluation. In this case study, a management population of 72 were actively engaged in all three outcomes.

Originality/value
– Appreciative Inquiry used as an evaluation tool ensured that managers had an active role in creating impact stories. The resultant discourse was the collaborative effort of 72 managers. The evaluation research was the co-creation of managers working in cross business and multi level action learning sets.
360 degree assessments of team role behaviours in different contexts
Authors: Manning Tony 
Published: September 2013

Purpose
– This article aims to present and discuss research findings on 360 degree assessments of team role behaviours in different contexts. In so doing, it brings together and develops two themes previously explored by the author, namely: the need to introduce a significant social dimension into thinking about team roles; the need to recognise that appropriate leadership behaviour is not universal but contingent upon context.

Design/methodology/approach
– A mixed sample of public sector managers in the UK completed a team role self-assessment questionnaire and had a 360 degree assessment completed on them. The research looked at the degree of correlation between the self-assessments and the 360 assessments and its statistical significance, exploring the ways in which the nine team roles are more or less valued in different contexts.

Findings
– Statistically significant relationships were found between measures of leadership contexts and team role behaviours. More importantly for this research, 360 degree assessments of team role behaviours were also found to vary in different contexts. Similarities and differences were found in the team roles behaviours that were typical in particular contexts and those that were valued in such contexts.

Research limitations/implications
– The range of contexts explored in this article was limited. Two contextual variables derived from the model of “dynamic” leadership were examined, namely the level of influence over change and the level of influence over others. In both cases, high and low levels of influence were considered. It would be useful to explore other contextual variables. It would also be useful to see if the observed relationships were found in situations other than the UK public sector.

Practical implications
– First, the findings reinforce the view that there is a significant social dimension to team roles, they cannot be viewed merely as clusters of personality traits, they are related to social roles and the influence people have in such roles. Second, teams are likely to be more effective if the behaviour of individual team members is appropriate to the social roles and contexts that they find themselves in. Third, what people tend to do in particular situations is not necessarily the same as that which is valued in such situations.

Originality/value
– The findings reinforce the conclusions of earlier research by the author and associates. In so doing, they lend support to original team role and leadership models developed by these individuals, as well as highlighting links between the two models. They also highlight differences between what people tend to do in particular situations and what is likely to be valued in such situations.
