Abstract
Plant growth and organ formation depend on the oriented deposition of load-bearing cellulose microfibrils in the cell wall. Cellulose is synthesized by a large relative molecular weight cellulose synthase complex (CSC), which comprises at least three distinct cellulose synthases. Cellulose synthesis in plants or bacteria also requires the activity of an endo-1,4-β-d-glucanase, the exact function of which in the synthesis process is not known. Here, we show, to our knowledge for the first time, that a leaky mutation in the Arabidopsis (Arabidopsis thaliana) membrane-bound endo-1,4-β-d-glucanase KORRIGAN1 (KOR1) not only caused reduced CSC movement in the plasma membrane but also a reduced cellulose synthesis inhibitor-induced accumulation of CSCs in intracellular compartments. This suggests a role for KOR1 both in the synthesis of cellulose microfibrils and in the intracellular trafficking of CSCs. Next, we used a multidisciplinary approach, including live cell imaging, gel filtration chromatography analysis, split ubiquitin assays in yeast (Saccharomyces cerevisiae NMY51), and bimolecular fluorescence complementation, to show that, in contrast to previous observations, KOR1 is an integral part of the primary cell wall CSC in the plasma membrane.
MYB5 and MYB14 Play Pivotal Roles in Seed Coat Polymer Biosynthesis in Medicago truncatula
Authors: Liu Chenggang , Jun Ji Hyung , Dixon Richard A. 
Published: June 2014

Abstract
In Arabidopsis (Arabidopsis thaliana), the major MYB protein regulating proanthocyanidin (PA) biosynthesis is TT2, named for the transparent testa phenotype of tt2 mutant seeds that lack PAs in their coats. In contrast, the MYB5 transcription factor mainly regulates seed mucilage biosynthesis and trichome branching, with only a minor role in PA biosynthesis. We here characterize MYB5 and MYB14 (a TT2 homolog) in the model legume Medicago truncatula. Overexpression of MtMYB5 or MtMYB14 strongly induces PA accumulation in M. truncatula hairy roots, and both myb5 and myb14 mutants of M. truncatula exhibit darker seed coat color than wild-type plants, with myb5 also showing deficiency in mucilage biosynthesis. myb5 mutant seeds have a much stronger seed color phenotype than myb14. The myb5 and myb14 mutants accumulate, respectively, about 30% and 50% of the PA content of wild-type plants, and PA levels are reduced further in myb5 myb14 double mutants. Transcriptome analyses of overexpressing hairy roots and knockout mutants of MtMYB5 and MtMYB14 indicate that MtMYB5 regulates a broader set of genes than MtMYB14. Moreover, we demonstrate that MtMYB5 and MtMYB14 physically interact and synergistically activate the promoters of anthocyanidin reductase and leucoanthocyanidin reductase, the key structural genes leading to PA biosynthesis, in the presence of MtTT8 and MtWD40-1. Our results provide new insights into the complex regulation of PA and mucilage biosynthesis in M. truncatula.
Effect of ethical ideologies on ethical judgment of future accountants: Malaysian evidence
Authors: Ismail Suhaiza 
Published: June 2014

Purpose– The purpose of this paper is to investigate the effect of ethical ideologies on ethical judgments of future Malaysian accountants in general situations and based on the legality of the situations. The examination covers the relationships of both the specific ethical dimension (i.e. idealism and relativism) and the specific categories of ideology (i.e. absolutist and subjectivist) on ethical judgments.Design/methodology/approach– Using a questionnaire survey that comprises Ethical Position Questionnaire and ethical dilemma vignettes, 396 usable responses were received. In achieving the objectives, multivariate analysis of variance, correlations and univariate analysis of variance were performed.Findings– The study discovered a significant impact of ethical ideology on judgments regardless of the legality of the cases. In addition, the study found a significant positive and negative impact of idealism and relativism, respectively, on ethical judgment. Moreover, the study reported that absolutists are stricter whilst situationists are more lenient in making ethical judgments compared to other ideologies.Originality/value– The present study investigated the effect of ethical ideologies on ethical judgment, in general, as well as the effect on ethical judgment based on the legality of the ethical dilemma. This study also considered the effect of the two dimensions of ethical ideology – idealism and relativism – on ethical judgment and captured the four categories of ideology based on the taxonomy of ethical ideologies.

Published: June 2014

Purpose– The purpose of this paper is to explore the relationship between external integration and innovation outcomes in the Brazilian food companies.Design/methodology/approach– Based on a survey questionnaire with 84 participants from large and non-large food companies of Brazil, the paper has used linear regression to examine the relationship between external integration and innovation outcomes. Next, the paper used the Wilcoxon-Mann-Whitney Test to compare the two sets of companies, i.e. large companies (annual sales >US$5 million), and non-large companies (annual sales US$1-5 million).Findings– The paper found that external integration with suppliers and customers is positively related to innovation outcomes in food companies. Besides, radical innovation is directly related to large companies rather than non-large food companies. Furthermore, customer integration is perceived in large food companies rather than non-large. To the best of the knowledge, this is pioneering information in food companies.Research limitations/implications– This research has been tested based only on participants’ perceptions. Therefore, the findings should also be verified through of a longitudinal fashion or in deep study.Practical implications– The main practical implication lies with the embedding of these concepts in a research from the perspective of a developing economy. Seen in this light it is noteworthy that such findings may contribute to the understanding of innovation outcomes in other developing countries.Originality/value– There are few empirical studies that explore the relationship between external integration and innovation outcomes in food companies. Besides, there is little knowledge about differences between large and non-large food companies regarding to incremental and radical innovation. Our research is the first study analyzing these issues in large and non-large food companies in the Brazil.
Developing successful entrepreneurial ecosystems
Authors: Kshetri Nir 
Published: June 2014

Purpose– There are strong similarities and striking differences in Estonia's and South Korea's entrepreneurial ecosystems. The purpose of this paper is to seek to compare and contrast these two economies in terms of key indicators related to impacts, performance measures and determinants of entrepreneurship.Design/methodology/approach– The approach of this study can be described as theory building from multiple case studies. The analysis is based on secondary data from a number of sources related to impacts, performance measures and determinants of entrepreneurship.Findings– Among the major findings is that in order to shift to a higher gear, South Korea's entrepreneurial weakness must be addressed through broad institutional reforms that include the corporate governance, and policies and attitudes toward immigrants and immigration. In Estonia's case, while continuing attention must be paid to institutional reforms, immediate action is needed to improve policies that affect basic economic, technological and infrastructural conditions.Research limitations/implications– A crucial lesson from a comparison of these two economies is that multiple paths of entrepreneurial success exist.Practical implications– The lessons each can learn from the other to improve the entrepreneurial ecosystem are suggested. Other emerging, developing and less developed economies also have much to learn from the success paths of these two economies.Originality/value– This paper provides unique insights into alternative ways that emerging economies can follow to develop successful entrepreneurial ecosystems and achieve entrepreneurial success as well as advantages and limitations of the alternatives.
Hybrid entrepreneurship: the importance of passion
Authors: Thorgren Sara , Nordström Carin , Wincent Joakim 
Published: June 2014

Purpose– The purpose of this paper is to investigate the motives behind individuals’ choice to have parallel business-employment careers (hybrid entrepreneurship) with a particular focus on passion (i.e. to work with something one is passionate about) as the main motive.Design/methodology/approach– A survey was administered to 262 Swedish hybrid entrepreneurs. Hypotheses proposed associations of the individual's age at business start-up and weekly hours spent on the business with passion as the main motive for the hybrid form. Logistic regression was used to test the hypotheses.Findings– The results indicated that first, the ability to work with something one is passionate about is the top motive for combining employment with a side business; second, passion is more likely to be the main motive behind the hybrid form among individuals who are older at business start-up; third, passion is less likely to be the main motive behind the hybrid form among individuals who spend more time on the business.Research limitations/implications– The study focusses on passion as motive for hybrid entrepreneurship, and in doing so, it does not test the extent to which hybrid entrepreneurs experience passion.Practical implications– The results support the popular notion that passion drives people to have parallel business-employment careers. Findings indicating that passion as a motive is more common among those who are older at start-up and less common among those who spend more time on the business suggest the importance of acknowledging hybrid entrepreneurs’ various profiles when approaching them in research and practice.Originality/value– This is the first study on motives behind hybrid entrepreneurship.

Authors: Feng Kaidong , Shen Qunhong , Zhao Shuming 
Published: June 2014

Purpose– This paper aims to explore the relationship between the role of entrepreneurs and the innovation investment propensity of Chinese firms. This study is expected to enhance our understanding about the competence building of top management team for innovative development.Design/methodology/approach– The analytical framework draws upon the recent theoretical progress about innovative firms, cognition and competence building of top managers. A horizontal data comparison and four longitudinal case studies of representative firms in the Chinese power equipment industry are implemented.Findings– The cognitive backgrounds of top managers, which have a significant role in directing strategic resource allocation, are found to be influenced by institutional environments. Because the institutional environments which are under the Chinese transition impact different groups of firms in different ways, the relevant practices of these firms lead to dissimilar competence building of top managers.Originality/value– This paper establishes a nexus of “institutional influence–cognition–resource allocation”. Such a nexus highlights the role of cognition of top managers in influencing the strategy-making of firms. So it helps in explaining the conditions for competence building in firms.

Authors: Yuan Ling , Yu Yue , Li Jian , Ning Lutao 
Published: June 2014

Purpose– The aim of this research is to study the relationships between occupational commitment, industrial relations and turnover intention, as well as the moderating role of turnover intention.Design/methodology/approach– Empirical data for this study were collected using a questionnaire survey method. A total of 600 copies of the questionnaire were sent out by post or email to firms and 429 valid responses were finally obtained, yielding a response rate of approximately 71.5 per cent.Findings– Except for the limited choices commitment, affective commitment, normative commitment and cumulative costs commitment are found to be significantly and positively related to industrial relations. Employees’ turnover intention may be detrimental to industrial relations, as our results show that it has a negative correlation with industrial relations. We also find that it negatively moderates the relationship between occupational commitment and industrial relations.Practical implications– Our results shed light on human resource management practices in Chinese firms, and managerial implications are made to enhance Chinese employees’ occupational commitment.Originality/value– This study extends the current literature and provides new insights into the relationship between the four dimensions of occupational commitment and industrial relations in the Chinese context. It also provides an understanding that this relationship is conditioned on employees’ turnover intention.
Simple and efficient numerical tools for the analysis of parachutes
Authors: Flores Roberto , Ortega Enrique , Onate Eugenio 
Published: June 2014

Purpose
– The purpose of this paper is to describe a set of simple yet effective, numerical method for the design and evaluation of parachute-payload system. The developments include a coupled fluid-structural solver for unsteady simulations of ram-air type parachutes. The main features of the computational tools are described and several numerical examples are provided to illustrate the performance and capabilities of the technique.

Design/methodology/approach
– For an efficient solution of the aerodynamic problem, an unsteady panel method has been chosen exploiting the fact that large areas of separated flow are not expected under nominal flight conditions of ram-air parachutes. A dynamic explicit finite element solver is used for the structure. This approach yields a robust solution even when highly nonlinear effects due to large displacements and material response are present. The numerical results show considerable accuracy and robustness.

Findings
– A simple and effective numerical tool for the analysis of parachutes has been developed.

Originality/value
– An analysis code has been developed which addresses the needs of ram-air parachute designers. The software delivers reasonably accurate results in a short time using modest hardware. It can therefore assist the design process, which nowadays relies on empirical methods.
How can mega events and ecological orientation improve city brand attitudes?
Authors: T. Marin-Aguilar Jose , Vila-López Natalia 
Published: June 2014

Purpose– The purpose of this study is to examine to what extent emotional experiences lived in mega-events and ecological orientation of citizens could act as direct antecedents of city brand attitude improvements. In addition, it addresses the effect in terms of a perceived quality of life that a city brand consolidation would be able to bring the citizens of a particular place. Cities must manage and administer their geographical territories as if they were brands, seeking to increase the benefits to society.Design/methodology/approach– An empirical study was performed by collecting information from 398 residents of Aguascalientes (Mexico) during the National Fair of San Marcos in 2011.Findings– Results show how in order to increase city brand attitudes, both the focus on mega-events and the ecological orientation are two successful ways. Moreover, improvements in city brand attitudes can bring significant benefits on the positive perception of quality of life among citizens.Originality/value– This investigation has made progress in implementing the experiential marketing channeled through emotional experiences in mega-events and, particularly, in environmentally oriented mega-events, which is able to improve ecological orientation of citizens. To date, no evidence of empirical research referenced in mega-events of the features of the National Fair of San Marcos, Mexico, exists.
Triggers and inhibitors of illegitimate customer complaining behavior
Authors: (Joy) Huang Zhuowei , Zhao Chen , Miao Li , Fu Xiaoxiao 
Published: June 2014

Purpose– The study aims to investigate the illegitimate customer complaining behavior (ICCB) in the hospitality industry from the perspective of frontline employees. In particular, this study identified ICCB incidents, ICCB triggering factors and inhibitors in the hospitality industry.Design/methodology/approach– A qualitative research approach was adopted in this study by using in-depth personal interviews. Twenty-six semi-structured interviews were conducted with frontline employees who had first-hand experiences with ICCB in the hospitality industry. The interviews were transcribed, coded and analyzed following the procedures of open coding, axial coding and selective coding.Findings– Analysis of the qualitative data has revealed 7 types of ICCB incidents, 11 ICCB triggering factors and 3 ICCB inhibitors in the hospitality industry, as perceived by frontline employees. The study also proposed a multiple-layer model of ICCB triggers and inhibitors based on the results. Four propositions are developed delineating three layers of driving forces and the dynamics between ICCB triggers and inhibitors that exert joint effects on ICCB.Research limitations/implications– Impacts of various cultural settings, different hospitality business settings (hotels vs restaurants) and profile information of frontline employees on ICCB need to be examined in future research.Originality/value– Findings of this study contribute to the customer complaining literature and the hospitality service management literature by offering the frontline employees’ perspective of ICCB. Hospitality businesses can benefit from this study by using the research findings to develop more effective company policies and training programs to recognize, monitor and resolve ICCB incidents.
Stakeholder management in disaster restoration projects
Authors: Baroudi Bassam , R. Rapp Randy 
Published: June 2014

Purpose– This paper aims to identify stakeholder issues on disaster restoration projects from a contractor perspective. Disaster occurrences normally warrant substantial restoration and reconstruction efforts. These projects involve the mitigation and repair of disaster-affected buildings and structures.Design/methodology/approach– This study is essentially exploratory in nature. It reviews relevant literature and then presents empirical research findings garnered from disaster restoration practitioners. A survey using the Likert rating scale method was used. The data were collected via an online questionnaire survey.Findings– The results confirm that disaster restoration projects contain significant stakeholder issues and challenges. Furthermore, these can differ from conventional construction and the work of “first responders” to disaster situations. Hence, disaster restoration projects are seen as having their own unique identity.Research limitations/implications– This paper has only set out to uncover stakeholder issues on disaster restoration projects. Future research that delves into the issues in greater depth would be useful.Practical implications– Disaster restoration practitioners need to be aware of conflicting stakeholder interests. These need careful management so that stakeholder issues do not impact successful project outcomes. Hence, informing industry (and academia) on these issues carries significant importance.Originality/value– Past research has tended to adopt macro perspectives on disaster preparedness, response and management. This research focuses on repairing and restoring disaster-affected buildings and structures from a restoration industry standpoint. The findings should be useful to the global disaster restoration community and those in associated fields.

Combining qualitative methods in practice
Authors: Carù Antonella , Cova Bernard , Pace Stefano 
Published: June 2014

Purpose– The purpose of this paper is to discuss within a corporate context the advantages and limitations of combining different qualitative methods (namely consumers’ introspection and observation) to grasp consumer experiences.Design/methodology/approach– The paper reflexively examines the evolution of a research process through which a team of researchers and a company tried to understand how the online consumer experience unfolds. The paper discusses the research process, the problems addressed and the way results were shared and acted upon within the company.Findings– The findings show how the search for and implementation of the combination of observation and introspection is rooted in the kinds of organizational change processes that allow companies to appropriate new methodological approaches and modify the conduct of their service innovation processes.Research limitations/implications– The paper is based on a single research project, analysed only retrospectively and reflexively. As to its implications, the proposed qualitative methods help mediate the collaborative interaction between researchers and the company during a research project.Practical implications– The research findings already have been appropriated and used by a multidisciplinary working group, operating within a corporate environment. Similarly, other companies can manage this type of research process following three major guidelines: prepare the cultural background, be iterative and maintain a conversation.Originality/value– The paper offers a unique account of the process of using combined qualitative methods within a company to understand consumer experiences.
