Abstract
In higher plants, blue light (BL) phototropism is primarily controlled by the phototropins, which are also involved in stomatal movement and chloroplast relocation. These photoresponses are mediated by two phototropins, phot1 and phot2. Phot1 mediates responses with higher sensitivity than phot2, and phot2 specifically mediates chloroplast avoidance and dark positioning responses. Here, we report the isolation and characterization of a Nonphototropic seedling1 (Nps1) mutant of tomato (Solanum lycopersicum). The mutant is impaired in low-fluence BL responses, including chloroplast accumulation and stomatal opening. Genetic analyses show that the mutant locus is dominant negative in nature. In dark-grown seedlings of the Nps1 mutant, phot1 protein accumulates at a highly reduced level relative to the wild type and lacks BL-induced autophosphorylation. The mutant harbors a single glycine-1484-to-alanine transition in the Hinge1 region of a phot1 homolog, resulting in an arginine-to-histidine substitution (R495H) in a highly conserved A′α helix proximal to the light-oxygen and voltage2 domain of the translated gene product. Significantly, the R495H substitution occurring in the Hinge1 region of PHOT1 abolishes its regulatory activity in Nps1 seedlings, thereby highlighting the functional significance of the A′α helix region in phototropic signaling of tomato.

Authors: Gallichan Deanna J , George Carol 
Published: February 2014

Purpose
– The purpose of this paper is to explore the potential of the Adult Attachment Projective Picture System (AAP) as a measure of attachment state of mind in adults with intellectual disabilities. The AAP is a free response picture system method of assessing patterns of adult attachment with established validity and reliability in community and clinical samples.

Design/methodology/approach
– The paper reports on five cases of adults with intellectual disabilities who were administered the AAP as part of routine clinical work. The AAP administration procedure was modified to take account of the participants’ intellectual disabilities.

Findings
– It was possible to code and classify each AAP using the established coding and classification system. The authors coded four cases blind to each other
'
s classification; they agreed on classifications for three cases and reached consensus on the fourth. The AAP analysis showed strong correspondence with case history material.

Originality/value
– The AAP demonstrates the potential to assess attachment state of mind in adults with intellectual disabilities and is the first developmental measure of attachment status that has shown potential in this population. The paper discusses clinical application of the AAP and directions for future research.
Collaboration strategies for a transition economy: measuring culture in Albania
Authors: Rao Vajjhala Narasimha , David Strang Kenneth 
Published: February 2014

Purpose– The researchers in this study reviewed the literature to locate the most relevant multicultural theories, factors, and instruments in order to measure Albania's national culture. The paper aims to discuss these issues.Design/methodology/approach– An innovative combination of exploratory and confirmatory factor analysis was used to fit the multicultural construct to the sample data and then estimate the national culture (n=73). The multicultural indexes were calculated for five generally accepted national culture factors to compare with the benchmarks published in the literature.Findings– The multicultural indexes were calculated for five generally accepted national culture factors to compare with the benchmarks published in the literature. An asymmetric plot was created for critical comparison of Albania with five other theoretically selected countries, using the indexes for PDi, ICi, MFi, UAi, and LTi. Albania was found to be most similar to its Balkan and Turkish neighbors, as compared with Asian or Western cultures such as that of the USA.Research limitations/implications– The researchers discussed the implications of knowing Albania's national culture profile with reference to how other countries might collaborate and transact with this emerging transition economy.Practical implications– From a business standpoint, the multicultural indexes for Albania provide general indicators of the national beliefs, norms and values, which foreign organizations may compare to their own cultural profile when interacting with professionals in this country. The best use for such indexes is for benchmarking and comparison. Foreign government, private corporations, or nonprofit organizations may compare their own culture profile with that of Albania to be aware of the similarities and differences.Originality/value– Albanian national culture was estimated for the first time in the literature, using a five-factor model adapted from the work of Hofstede.
Challenges and conceptions of globalization
Authors: Bond Christopher , J. O'Byrne Darren 
Published: February 2014

Purpose– This paper, which is conceptual in both nature and approach, builds on a recent contribution to the theorization of “globalization” and seeks to utilise the framework developed therein to help promote a more complex conceptual understanding of the potential implications of how business operates and responds to these challenges in a global environment. The paper aims to discuss these issues.Design/methodology/approach– The paper draws primarily on a heuristic framework developed by O'Byrne and Hensby that reviews eight models of global change. In this paper, the authors review and give consideration to the relationship between these models and business practice and contend that this relationship is far more complex than the majority of the current literature in the business and management field represents. Within the paper, the authors explore and discuss the dynamics of the eight models of “globalization” and assess the potential implications for business practice of working within these often conflicting and contradictory paradigms of “globalization”. As part of this review, the authors consider the strategic implications of “globalization” for business practice and propose a conceptual model with eight strategic options which are aligned to the eight models of global change.Findings– The paper presents a tentative heuristic framework seeking to align the eight models of global change with strategic options that companies might peruse in response to the global forces for change. The paper concludes by advocating a more integrative and complex understanding of globalization than is currently the case and identifies potential for further research in this area.Originality/value– The paper develops a conceptual framework for assessing the challenges that processes of globalization present to business. The paper places a particular emphasis on considering the strategic implications of the various models of global change and offers a tentative framework for further debate and discussion.
Non-financial employment commitment: some correlates and a cross-national comparison
Authors: Snir Raphael 
Published: February 2014

Purpose– To further explore the nature of non-monetary motivation for working, this study aims to present correlates of non-financial employment commitment (NFEC) and a cross-national comparison.Design/methodology/approach– Data gathered from representative national samples of the adult population (i.e. employed and unemployed individuals) in 31 countries (n=43,440), among them Nordic (e.g. Sweden and Norway), Western-European (e.g. Spain and France), Anglo-Saxon (e.g. the USA and Britain), former Communist (e.g. Russia and Hungary), Asian (e.g. Japan and South Korea), Latin-American (Mexico and the Dominican Republic), and African (South Africa). The source of the data is the 2005 International Social Survey Programme module on work orientation.Findings– NFEC proves positively correlated with intrinsic job characteristics, education level, job satisfaction, and organizational commitment. Administrators, managers, and professionals have higher NFEC than blue-collar workers, clerks, service workers, and sales workers. Respondents currently working for pay have higher NFEC than those currently not working for pay. Respondents trying to improve job skills during the previous 12 months have higher NFEC than those not trying to do so. NFEC is higher in member countries of the Organization for Economic Co-operation and Development than in non-member countries. NFEC is also higher in countries where self-expression values are important than in countries where survival values are important.Practical implications– By assessing NFEC decision makers may be assisted in their selection and advancement decisions.Originality/value– This study conducts the most comprehensive cross-national comparison of NFEC to date, and its findings have high external validity. It is unlikely that the findings are biased by social desirability.
Cross-cultural factorial validity of the academic motivation scale
Authors: Osei Akoto Edward 
Published: February 2014

Purpose– The purpose of this study was to examine the factorial validity of the academic motivation scale (AMS), including mean structures and reliabilities across two culturally diverse samples. Thus, the study assesses the fit of the seven-factor conceptualization of AMS to a non-Western context.Design/methodology/approach– Survey questionnaire was used to elicit responses from undergraduate business students from universities in the USA (267) and Ghana (262). The data were analyzed using the multi-group CFA technique in LISREL 8.7, to assess measurement equivalency and the fit of the AMS to the non-Western context.Findings– After baseline models were established, a hierarchy of successively restrictive models were specified and estimated. Support was found for factorial, metric, and scalar invariance across the two samples, but different levels of psychometric soundness exist.Research limitations/implications– In spite of the low reliabilities in the non-Western context, the AMS has the potential to measure the same traits in the same way across diverse groups.Practical implications– Researchers, educators, and policy makers interested in this field of study may be confident in employing the AMS to investigate students' motives, including cross-cultural motivational studies. Organizations may also use the AMS as a pre-employment tool to understand college graduates motivational profile for better person-organization match.Originality/value– The AMS has been developed and validated in the Western context, but its validity in non-Western contexts remains unexplored. This study provides a cross-cultural comparative test of the seven-factor conceptualization.
Building successful internships: lessons from the research for interns, schools, and employers
Authors: P. Maertz Jr Carl , A. Stoeberl Philipp , Marks Jill 
Published: February 2014

Purpose– “What kinds of internships are possible?” “How should we decide whether to utilize internships, and if so, how can we ensure they will pay off?” The purpose of this paper is to help answer these key questions facing talent management professionals, educators, and interns.Design/methodology/approach– This is achieved by reviewing the scattered literature to distill the lessons regarding internships for each of these stakeholders. First, the paper better defines internships through enumerating 11 key dimensions, helping give all internship stakeholders a common language to clarify communication. Second, the paper synthesizes and lists the potential benefits and costs/pitfalls of internships for interns, schools, and employers to provide a fuller view of internships from all stakeholder perspectives. Third, the paper summarizes recommendations to help stakeholders maximize the actual benefits obtained from internships while minimizing the costs and avoiding common pitfalls.Findings– Many benefits for interns have been identified in the literature. These can be categorized as job-related benefits, career-related benefits, and networking/job market benefits. For most interns, the costs of the internship are minimal. Nevertheless, potential pitfalls stem from the fact that employers and interns often do not have consistent or shared expectations regarding the internship. The benefits of internships for schools can be significant. These include filling an important modern need for experiential and vocational learning. For employers, hiring an intern for a full-time position after the assignment can lead to savings in the areas of recruitment and selection.Originality/value– The paper provides stakeholders with “one-stop shopping” for the best general advice about creating and growing successful internships.
Bi-objective sizing optimization of power converter using genetic algorithms
Authors: Mejbri Hanen , Ammous Kaiçar , Abid Slim , Morel Hervé , Ammous Anis 
Published: February 2014

Purpose
– This paper aims to focus on the trade-off between losses and converter cost.

Design/methodology/approach
– The continual development of power electronic converters, for a wide range of applications such as renewable energy systems (interfacing photovoltaic panels via power converters), is characterized by the requirements for higher efficiency and lower production costs. To achieve such challenging objectives, a computer-aided design optimization based on genetic algorithms is developed in Matlab environment. The elitist non-dominated sorting genetic algorithm is used to perform search and optimization, whereas averaged models are used to estimate power losses in different semiconductors devices. The design problem requires minimizing the losses and cost of the boost converter under electrical constraints. The optimization variables are, as for them, the switching frequency, the boost inductor, the DC capacitor and the types of semiconductor devices (IGBT and MOSFET). It should be pointed out that boost topology is considered in this paper but the proposed methodology is easily applicable to other topologies.

Findings
– The results show that such design methodology for DC-DC converters presents several advantages. In particular, it proposes to the designer a set of solutions – as an alternative of a single one – so that the authors can choose a posteriori the adequate solution for the application under consideration. This then allows the possibility of finding the best design among all the available choices. Furthermore, the design values for the selected solution were obtainable components.

Originality/value
– The authors focus on the general aspect of the discrete optimization approach proposed here. It can also be used by power electronics designers with the help of additional constraints in accordance with their specific applications. Furthermore, the use of such non-ideal average models with the multi-objective optimization is the original contribution of the paper and it has not been suggested so far.
Adjusted reactive solutions for multiple power flow computations
Authors: Genesi Camillo , Montagna Mario 
Published: February 2014

Purpose
– The purpose of this work is that of showing some efficient techniques to perform PV-PQ node type switching in multiple power flow computations.

Design/methodology/approach
– Reactive generation limits of generation buses must be taken into account to obtain realistic power flow solutions. This may result computationally demanding when many power flow computations are required as in contingency screening or Monte Carlo simulations. In the present paper, the implementation of efficient PV-PQ node type switching is examined with particular emphasis on the efficiency of computation. Some different methods are proposed and compared on the basis of computation speed and accuracy.

Findings
– Tests show the efficiency of the proposed methods with reference to actual networks with up to 800 buses.

Originality/value
– The classical method of (partial) re-factorisation is not very efficient when many power flow solutions are to be evaluated. In the present work, a different approach is proposed; it is based on grounding each PV node by a fictitious short-circuit branch which is removed when the node type is changed to PQ. This operation is carried out by compensation of the solution and combined with the modifications required for contingency simulation.

Authors: Birla Nidhika , Swarup Akhilesh 
Published: February 2014

Purpose
– This paper aims to determine the optimal preview length for the preview state feedback controller and to design the static preview gains for the controller.

Design/methodology/approach
– The design methodology is based on LMI formulations and Bisection Approach to determine the optimal preview length for the preview state feedback controller that achieves robust H∞ performance. The determination of the optimal preview length is such that the performance of the optimized controller is similar (within bounds) to the maximum length controller, in terms of transient and frequency response along with the H∞ performance.

Findings
– The proposed algorithm is implemented for two benchmark design examples that verify its ability and applicability. The results show that the optimal preview length controller designed using the proposed method performs similar to the maximum length preview controller (within bounds) and better than reported in literature.

Originality/value
– The paper discusses the novel algorithm formulation and its proof as no such method is available to determine the optimal preview length.
On the equivalence of finite difference and edge element formulations in magnetic field analysis using vector potential
Authors: Demenko Andrzej , Sykulski Jan 
Published: February 2014

Purpose
– Numerical three-dimensional formulations using vector potential A have been examined for magnetic fields, with emphasis on the finite difference (FDM) and edge element (EEM) methods, with the view to establish common features. The paper aims to discuss these issues.

Design/methodology/approach
– It has been shown that for hexahedral elements the FDM equations may be presented in the form similar to the EEM equations, providing the products of the nodal potentials and distances between the nodes are used as unknowns in FDM, instead of the usual nodal potentials.

Findings
– The analogy between the FDM and the EEM approach has been established.

Originality/value
– It has been demonstrated, following from this and previous publications, that analogy exists between all fundamental methods of field solutions relying on space discretisation. This is helpful in terms of classification of the methods and aids the understanding of physical processes involved.
Examination of eddy current in laminated core without insulation
Authors: Takahashi Norio , Akagi Akira , Nakano Masanori , Doi Yuhito , Miyagi Daisuke 
Published: February 2014

Purpose
– In the laminated core of transformer, motor, etc. each electrical steel sheet is usually insulated in order to reduce the eddy current loss. Raw steel sheets without insulation are sometimes used in a small core of electrical machines and electronic equipments, because the cost of iron core can be reduced if cheap steel sheets without insulation are used in the core. The purpose of the paper is to show how the contact resistance between sheets of laminated core affects the interlaminar eddy current and to show the criterion for judgment of the necessity of insulation.

Design/methodology/approach
– The eddy current losses of core made of SPCC (cold rolled steel sheets) of different widths with and without insulation under various conditions are analyzed by using the finite element method (FEM) considering the contact resistance. The equivalent circuit for such a laminated core without insulation is shown. The experimental investigation is also carried out.

Findings
– A criterion for the judgment of insulation is examined. It is shown that the increase of eddy current is affected by the ratio (this corresponds to the criterion) of the resistance of steel and the contact resistance.

Originality/value
– The paper clarifies a criterion for the necessity of insulation between sheets of laminated core. It is shown that a similar tendency to the measured value of eddy current loss can be obtained by utilizing the modeling method of laminated core.

Authors: Yang Wenjia , Zhou Haijuan , Li Yuling 
Published: February 2014

Purpose
– The purpose of this paper is to report the investigations on the potential of a new evolutionary algorithm based on probabilistic models – the quantum-inspired evolutionary algorithm (QEA) in solving inverse problems.

Design/methodology/approach
– An improved QEA.

Findings
– The proposed algorithm is an efficient and robust global optimizer for solving inverse problems.

Originality/value
– To enhance the convergence speed without compromising the diversity performances of the populations, a new definition of global information sharing is introduced and implemented. To guarantee the balance between exploration and exploitation searches, a different migration strategy and formula, as well as a novel formulation for adaptively updating the rotation angle, are developed.

Authors: Thirukumaran Sanmugasundaram , Ratnamahilan Polycarp Hoole Paul , Ramiah Harikrishnan , Kanesan Jeevan , Pirapaharan Kandasamy , Ratnajeevan Herbert Hoole Samuel 
Published: February 2014

Purpose
– As commercial and military aircraft continue to be subject to direct lightning flashes, there is a great need to characterize correctly the electrical currents and electric potential fluctuations on an aircraft to determine alternative design approaches to minimizing the severity of the lightning-aircraft dynamics. Moreover, with the increased severity of thunderstorms due to global warming, the need arises even more to predict and quantify electrical characteristics of the lightning-aircraft electrodynamics, which is normally not measurable, using a reliable electric model of the aircraft. Such a model is advanced here. The paper aims to discuss these issues.

Design/methodology/approach
– The case considered in this paper is that of an aircraft directly attached to an earth flash lightning channel. The paper develops a new approach to modelling the aircraft using electric dipoles. The model has the power to represent sharp edges such as wings, tail ends and radome for any aircraft with different dimensions by using a number of different sized dipoles. The distributed transmission line model (TLM) of the lightning return stroke incorporating the distributed aircraft model is used to determine aircraft electrical elements and finally the electric current induced on the aircraft body due to lightning's interaction with the aircraft. The model is validated by the waveform method and experimental results.

Findings
– The dipole model proposed is a very powerful tool for minute representation of the different shapes of aircraft frame and to determine the best geometrical shape and fuselage material to reduce electric stress. This charge simulation method costs less computer storage and faster computing time.

Originality/value
– The paper for the first time presents a computer-based simulation tool that allows scientists and engineers to study the dynamics of voltage and current along the aircraft surface when the aircraft is attached to a cloud to ground lightning channel.
