Authors: Hamza‐Reguig Sherazed , Louala Sabrine , Boualga Ahmed , Lamri‐Senhadji Myriem Y 
Published: May 2013

PurposeThe purpose of this paper was to evaluate the effect of sardine protein on the redox status in rats fed a cholesterol‐rich diet.Design/methodology/approachHypercholesterolemic rats were divided into two groups fed diets enriched with cholesterol and containing 20 percent of sardine proteins (SPc) or casein (CASc) for 28 days. A control group was fed a standard diet (CAS).FindingsAfter 28 days of experiment, no significant difference in serum total cholesterol triacylglycerols and uric acid was found with the three diets. Serum albumin content was, respectively, 2‐fold higher in SPc than those in CASc group. Compared to CAS, this value was 1.3‐fold lower in CASc group. In liver and heart, lipid peroxidation was 1.7‐ and 2‐fold lower in SPc compared with CASc and CAS, respectively. In red blood cells and epididymal fat, superoxide dismutase activity was, respectively, 1.3‐and 3‐fold higher in SPc compared to CASc. Epididymal fat and heart catalase activity were, respectively, elevated (+50 and +79 percent) in SPc than in CASc. Sardine protein decreased nitric oxide levels in heart and epididymal fat (twofold) compared to CASc but compared to control group, nitric oxide value was higher in epididymal fat (2‐fold) and liver (3‐fold).Originality/valueSardine protein exerts a beneficial action against oxidative stress caused by dietary cholesterol specifically in the heart by reducing lipid peroxidation and enhancing catalase activity.
“It's (not) the economy, stupid”: wasted opportunities (apologies to James Carville)
Authors: Skiba Michaeline , O'Halloran Patrick 
Published: May 2013

PurposeTaking a broad review of the management and economics literature, the purpose of this paper is to examine how the recent “Great Recession” has had a disproportionate adverse impact on US labor markets and created social disruptions to professional workers experiencing persistent unemployment or underemployment.Design/methodology/approachSecondary data analysis shows how the recent recession has had a disproportionate impact on employment. Recognizing underemployment as a potentially persistent state, the authors delineate the extent and consequences of underemployment.FindingsAnalyses of unemployment and underemployment resulting from the recent recession suggest it has had a particularly severe detrimental impact on worker benefits, incomes and employment prospects for most US workers.Research limitations/implicationsSecondary data analysis is a major limitation but results justify a call for further research into the potential increase in the long‐term economic displacement of professional workers.Originality/valueThis paper is unique in applying economic and management constructs in an analysis of the origins, consequences and recommendations for decreasing the rising level of underemployment among professional US workers.
Dynamics of entering politically risky foreign markets
Authors: Laynesa Alcantara Lailani , Mitsuhashi Hitoshi 
Published: May 2013

PurposeThe purpose of this paper is to examine the effects of political risk on firms' likelihood of foreign market entry and performance by adopting a strategic view of political risk and drawing upon the arguments of multimarket contact theory.Design/methodology/approachThis study estimates the location choice and performance of Japanese auto parts‐makers using panel regression models.FindingsThe study finds that firms with low multimarket contact in the home country and high multimarket contact in the host country are less likely to avoid politically risky host countries and that firms which entered politically risky host countries exhibit greater performance when the degree of multimarket contact with prior entrants is high.Research limitations/implicationsAlthough the research design raises a concern about the generalizability of the findings, this study highlights the strategic importance of politically risky markets and suggests the importance of considering competitive interactions with rivals in examining interdependent behavior in foreign direct investments.Practical implicationsInstead of consistently avoiding politically risky markets, managers should actively consider the potential strategic importance of these markets. A post‐entry strategy suggested by the findings is taking positive steps to leverage the benefits of multimarket contacts for managing subsidiaries in politically risky host countries.Originality/valueUnlike previous studies, this study emphasizes the strategic potential of politically risky markets and takes a view that firms have variable political risk tolerance. Furthermore, the authors' adoption of multimarket contact theory allows a novel approach to benchmarking against rivals for foreign entry decisions.
Language, cultural intelligence and expatriate success
Authors: Huff Kyle C. 
Published: May 2013

PurposeThe purpose of this paper is to examine how cultural intelligence (CQ) and language proficiency are related to cross‐cultural adjustment, expatriate satisfaction, and expatriate desires towards the future, to further what is known about CQ.Design/methodology/approachA quantitative survey was developed and administered to 140 native English‐speaking expatriates living in Japan who were participating in the Japan Exchange and Teaching program. The survey was designed to measure CQ, language proficiency, cross‐cultural adjustment, satisfaction with their work and life in Japan, and their attitudes towards future expatriate assignments.FindingsIn total, there were eight criterion variables used in the study. Results from a series of hierarchical regression analyses revealed that the four CQ factors and language proficiency to various degrees were able to predict the various criterion variables. Motivational CQ was the only predictor variable that was able to predict all criterion variables.Research limitations/implicationsThis paper provides solid quantitative research into CQ. However, since the data come from self‐report surveys, its limitations in terms of common method bias are recognized.Practical implicationsThis study identifies both language ability and CQ as predictive of expatriate adjustment. This information enables organizations to better prepare their members for expatriate assignments.Originality/valueAlthough prior research has investigated a number of these issues separately on various types of samples, this paper is the first to combine all the variables into one study using expatriates.
The relationship between Theory X/Y: assumptions and communication apprehension
Authors: Russ Travis L. 
Published: May 2013

PurposeThis study seeks to explore whether McGregor's Theory X/Y assumptions are related to managers’ communication apprehension (CA) – their degree of comfort when interacting with others.Design/methodology/approachSurveys measuring Theory X/Y assumptions and CA were administered to 281 full‐time managers from divergent industries across the USA. Hypotheses were tested using correlations.FindingsModerate scores on the Theory X scale were positively correlated with traitlike CA and CA in interpersonal contexts. Managers’ total and high scores on the Theory Y scale were negatively correlated with traitlike CA and CA in groups, interpersonal conversations, and meetings. Moderate scores on the Theory Y scale were positively correlated with CA in groups. Low scores on the Theory Y scale were positively correlated with traitlike CA and CA in interpersonal and public speaking settings.Originality/valueThis study extends the broad landscape of literature on management communication. Findings deepen our understanding of how managers’ communicative dispositions are linked to their Theory X/Y assumptions.
Perceptions and emotional experiences in differential supervisor‐subordinate relationships
Authors: Tse Herman H.M. , Troth Ashlea C. 
Published: May 2013

PurposeThe purpose of this research is to examine how employees perceive the differential quality of relationships with their supervisors, and their emotional experiences within the leader‐member exchange (LMX) process for these differential relationships.Design/methodology/approachThis qualitative study presents the interview findings of 25 full‐time employees working within five teams in two organizations.FindingsThe qualitative results revealed a consistent pattern of descriptors used by employees to differentially describe their high‐quality and low‐quality LMX relationships. A range of positive and negative emotions were experienced within the context of the LMX relationship and individuals reported different levels of positive and negative emotions for high‐quality versus low‐quality LMX relationships.Research limitations/implicationsA limitation is the reliance on self‐reports of the subordinate (not leader) in terms of the role of emotions in the LMX process.Practical implicationsThe authors contend that these findings increase understanding of the role of emotion in supervisor‐subordinate relationships and how this is reflected in relationships of differential quality. The findings also suggest ways to enhance the quality of leader member exchanges and ultimately improve employee experiences.Originality/valueAlthough the role of emotions in LMX has been theorized, this study is one of the first to use a workplace sample to empirically and qualitatively examine the role of emotions in supervisor‐subordinate relationships of differential quality.
A hybrid approach to knowledge flow
Authors: Lin Chinho , Wu Ju‐Chuan , Tsai Hua‐Ling 
Published: May 2013

PurposeThis study attempts to develop an approach with triangulation to explore the determinants of knowledge flows, as well as the relationships among them.Design/methodology/approachThe proposed approach with the use of triangulation is designed to handle the issues that arise in the various interactions and numerous contexts among entities and/or activities that are associated with KM.FindingsThe proposed hybrid approach is found to be helpful in dealing with the issue of knowledge flow, especially involving various entities and complex interactions with numerous contents and dynamic contexts. In addition, the findings also show the presence of multi‐directional and adaptive interactions among determinants to knowledge flows, and also how these influence a firm's KM initiatives and performance.Research limitations/implicationsThe proposed hybrid approach can be considered as a way to overcome the limitations both of qualitative and quantitative methods, and the relationships among knowledge flows explored in this study provide some directions for future KM research.Practical implicationsThe proposed approach focuses on the visualization of probable determinants to knowledge flows within an organization. This visualization can be utilized to evaluate the determinants and their relationships with each other, which may help managers to take actions to achieve more effective and efficient KM.Originality/valueThe results show the value of using a hybrid approach for dealing with research issues involving various entities and activities with complex content, such as knowledge flows.
Information technology capability‐enabled performance, future performance, and value
Authors: Ong Chorng‐Shyong , Chen Poyen 
Published: May 2013

PurposeThe purpose of this paper is to simultaneously determine the impact of information technology capabilities on firm performance, future firm performance, and firm value.Design/methodology/approachThe secondary data for 480 matched‐firms are collected from InformationWeek (which provides the IT capabilities ranking) and the Compustat database (which provides financial data).FindingsThe results show that IT capabilities positively and significantly influence all three constructs and that the significance level of firm value is higher than that of firm performance and that of future firm performance. That is, IT capabilities are more relevant to firm value, which represents growth opportunities, intangible assets, and innovation, etc.Practical implicationsBased on these empirical findings that IT contributes more to the long‐term influences than to the short‐term influences, firm managers should pay more attention to the strategic positioning that IT provides for firms rather than only enhancing the operational effectiveness.Originality/valueThis study proposes a complete set of constructs, which includes firm performance, future firm performance, and firm value, to measure the different effects of information technology capabilities on firms and to discuss the corresponding managerial implications. Therefore, these three constructs can be further clarified and considered simultaneously. This has not been attempted by previous studies.
Event‐brand transfer in an entertainment service: experiential marketing
Authors: Vila‐López Natalia , Rodríguez‐Molina MaCarmen 
Published: May 2013

PurposeOne of the channels a brand can use to create experiences is events. The brand promoting the event and its sponsors can obtain various benefits in the form of brand image, personality and notoriety. The main aim of this research is to evaluate the effects that experiencing an event has on experience with the promoting brand.Design/methodology/approachThe study analysed the musical event MTV Winter Festival 2010, considering the opinion of 127 attendees to discover the impact of experiencing the MTV entertainment television channel event in three areas: improved brand experience, improved brand personality and increased brand reputation. EQS was used to test the proposed model.FindingsRegarding event experience antecedents, “immersion” has been identified as the most important one and brand experience as an important effect. Also, brand experience has been found to have a positive impact on exciting brand personality and exciting brand personality in turn on brand reputation.Originality/valueAlthough two of the hypotheses on the antecedents of emotional event experience (“surprise” and “participation”) were not confirmed, it can be said that progress has been made on the benefits of marketing experiences since this is the first empirical investigation to deal with the connection of event‐brand experiences in the area of the arts.
Key factors of teenagers' mobile advertising acceptance
Authors: Martí Parreño José , Sanz‐Blas Silvia , Ruiz‐Mafé Carla , Aldás‐Manzano Joaquin 
Published: May 2013

PurposeThe purpose of this paper is to analyse key drivers of teenagers' attitude toward mobile advertising and its effects on teenagers' mobile advertising acceptance.Design/methodology/approachA proposed model of affective (irritation and entertainment) and cognitive (perceived usefulness) antecedents of attitude toward mobile advertising and its effects on mobile advertising acceptance is analysed. The sample consisted of 355 Spanish teenagers. The model was tested using structural equation modelling.FindingsFindings show that entertainment, irritation and usefulness are key drivers of teenagers' attitude toward mobile advertising. Moreover, perceived usefulness reduces irritation. The authors' model also suggests that improving teenagers' attitude toward mobile advertisements is a key factor for teenagers' mobile advertising acceptance.Practical implicationsThis research offers practical implications for marketing managers interested in targeting mobile advertising campaigns to teenagers. Marketers should take care of the number and frequency of messages being sent in order to avoid teenagers being irritated by their advertising attempts. Marketers can improve attitude through message personalization, content relevance and enriching the sales messages with entertainment features.Originality/valueWhile consumer‐driven factors such as perceived control or trust have deserved a lot of attention, little research has focused on the role of emotions on attitude and behaviour towards mobile advertising. This paper combines the influence of cognitive and affective message‐driven factors on teenagers' attitude and behaviour towards mobile advertising.

Authors: Liébana‐Cabanillas Francisco , Muñoz‐Leiva Francisco , Rejón‐Guardia Francisco 
Published: May 2013

PurposeThe aim of this paper is to contribute to the field of satisfaction research from the perspective of electronic banking users; a topic of great interest to the business strategies of financial institutions. In this context, the authors analyse the main determinants of user experience with a specific institution's products.Design/methodology/approachA comprehensive review of the scientific literature has justified the development of a behavioural model that explains satisfaction using a set of constructs or endogenous variables. Data was collected from a self‐administered web survey in the authenticated section of the electronic banking service of a prestigious financial institution.FindingsThe analysis tests the relationship between the proposed variables (accessibility, trust, ease of use and usefulness) and satisfaction with electronic banking.Research limitations/implicationsThe study was limited to the data of a single financial institution. Caution should therefore be exercised in generalising the results. The research results provide a number of valuable conclusions for financial institutions.Originality/valueThis paper is a pioneer study of satisfaction with electronic banking, especially of the relationships between satisfaction and its main determinants.
Aerodynamic shape optimization using the adjoint Euler equations
Authors: Straathof Michiel H. , Carpentieri Giampietro , van Tooren Michel J.L. 
Published: May 2013

PurposeAn aerodynamic shape optimization algorithm is presented, which includes all aspects of the design process: parameterization, flow computation and optimization. The purpose of this paper is to show that the Class‐Shape‐Refinement‐Transformation method in combination with an Euler/adjoint solver provides an efficient and intuitive way of optimizing aircraft shapes.Design/methodology/approachThe Class‐Shape‐Transformation method was used to parameterize the aircraft shape and the flow was computed using an in‐house Euler code. An adjoint solver implemented into the Euler code was used to compute the required gradients and a trust‐region reflective algorithm was employed to perform the actual optimization.FindingsThe results of two aerodynamic shape optimization test cases are presented. Both cases used a blended‐wing‐body reference geometry as their initial input. It was shown that using a two‐step approach, a considerable improvement of the lift‐to‐drag ratio in the order of 20‐30 per cent could be achieved. The work presented in this paper proves that the CSRT method is a very intuitive and effective way of parameterizating aircraft shapes. It was also shown that using an adjoint algorithm provides the computational efficiency necessary to perform true three‐dimensional shape optimization.Originality/valueThe novelty of the algorithm lies in the use of the Class‐Shape‐Refinement‐Transformation method for parameterization and its coupling to the Euler and adjoint codes.
Performance modeling and optimization for the stock preparation unit of a paper plant using genetic algorithm
Authors: Khanduja Rajiv , Tewari P.C. 
Published: May 2013

PurposeThis paper aims to deal with the performance modeling and optimization for the stock preparation unit of a paper plant using genetic algorithm. It provides the optimum unit availability level for different combinations of failure and repair rates of the subsystems of the stock preparation unit of the paper plant concerned.Design/methodology/approachEfforts have been made to develop the performance model based on a real situation for the stock preparation unit. The performance in terms of availability has been evaluated on the basis of Markov birth‐death process. After that, the performance optimization using genetic algorithm is performed, which gives the optimum unit availability levels for different combinations of failure and repair rates of the subsystems of stock preparation unit for enhancing the overall performance of the paper plant.FindingsThe effect of genetic algorithm parameters such as number of generations, population size and crossover probability on the unit performance, i.e. availability, has been analyzed and discussed with the concerned paper plant management. It is found that these results are highly beneficial to the maintenance engineers for the purpose of the effective maintenance planning to enhance the overall performance (availability) of stock preparation unit of the paper plant.Originality/valueMost other researchers have confined their work to the development and analysis of theoretical models which has little practical significance. To fulfill this deficiency, efforts have been made in the present work to develop a model based on real situation for stock preparation unit.
Excellence models in the non‐profit context: strategies for continuous improvement
Authors: Al‐Tabbaa Omar , Gadd Kenneth , Ankrah Samuel 
Published: May 2013

PurposeThis paper provides insights into the applicability of excellence models (in particular the European Foundation for Quality Management (EFQM) Excellence Model), for use in the nonprofit context as a strategy for performance improvement aiming to enhance sustainability.Design/methodology/approachThe study is based on an exploratory, qualitative in‐depth case study approach, which includes three UK‐based nonprofit organizations (NPOs) as research case studies.FindingsIn general, we found the quality models to be relevant to the NPO context, and potentially effective and useful as a performance improvement strategy for NPOs. However, we also propose some modifications to the EFQM model to address the specific characteristics of this sector. Additionally, we compare two of the most widely used quality models (EFQM and MBNQA), and suggest that although both are relevant for NPOs, the EFQM model has some superior advantages.Originality/valueThis paper contributes to the debate about the sustainability of organizations and the underpinning mechanisms behind their efficiency. Many researchers and practitioners are continually debating how an organization can optimize its available resources, as this is considered to be one of the primary foundations for organization sustainability. The added contribution of this paper advances this debate a step further by providing insights into how concepts and tools which have been initially designed for the for‐profit sector can be deployed by nonprofit organizations (NPOs). In addition, the paper provides further views about the approaches NPOs might use in response to the current political and financial challenges.
