Overexpression of a Calcium-Dependent Protein Kinase Confers Salt and Drought Tolerance in Rice by Preventing Membrane Lipid Peroxidation
Authors: Campo Sonia , Baldrich Patricia , Messeguer Joaquima , Lalanne Eric , Coca María , San Segundo Blanca 
Published: May 2014

AbstractThe OsCPK4 gene is a member of the complex gene family of calcium-dependent protein kinases in rice (Oryza sativa). Here, we report that OsCPK4 expression is induced by high salinity, drought, and the phytohormone abscisic acid. Moreover, a plasma membrane localization of OsCPK4 was observed by transient expression assays of green fluorescent protein-tagged OsCPK4 in onion (Allium cepa) epidermal cells. Overexpression of OsCPK4 in rice plants significantly enhances tolerance to salt and drought stress. Knockdown rice plants, however, are severely impaired in growth and development. Compared with control plants, OsCPK4 overexpressor plants exhibit stronger water-holding capability and reduced levels of membrane lipid peroxidation and electrolyte leakage under drought or salt stress conditions. Also, salt-treated OsCPK4 seedlings accumulate less Na+ in their roots. We carried out microarray analysis of transgenic rice overexpressing OsCPK4 and found that overexpression of OsCPK4 has a low impact on the rice transcriptome. Moreover, no genes were found to be commonly regulated by OsCPK4 in roots and leaves of rice plants. A significant number of genes involved in lipid metabolism and protection against oxidative stress appear to be up-regulated by OsCPK4 in roots of overexpressor plants. Meanwhile, OsCPK4 overexpression has no effect on the expression of well-characterized abiotic stress-associated transcriptional regulatory networks (i.e. ORYZA SATIVA DEHYDRATION-RESPONSIVE ELEMENT BINDING PROTEIN1 and ORYZA SATIVA No Apical Meristem, Arabidopsis Transcription Activation Factor1-2, Cup-Shaped Cotyledon6 genes) and LATE EMBRYOGENESIS ABUNDANT genes in their roots. Taken together, our data show that OsCPK4 functions as a positive regulator of the salt and drought stress responses in rice via the protection of cellular membranes from stress-induced oxidative damage.

This paper examines the objectives, criteria and prioritization of material for digitization. It further identifies the factors motivating users to access these digital resources.
Success factors of inter-organizational knowledge sharing: a proposed framework
Authors: Nooshinfard Fatemeh , Nemati-Anaraki Leila 
Published: May 2014

Purpose– The dynamism of new economy requires information professionals not only to create knowledge quickly but also to acquire and apply knowledge through knowledge sharing (KS). So, determining factors that may influence knowledge sharing within an organization or among organizations has become an important area of research. This paper aims to review determinant factors influencing inter- and intra-organizational knowledge sharing in order to offer a framework.Design/methodology/approach– The present paper proceeds in three phases. In the first phase, the published literature on knowledge sharing has been reviewed extensively with consideration of their empirical applications. Next, based on the understanding gained from the previous stage, a conceptual framework of successful factors for effective inter-organizational knowledge sharing has been proposed. In the third phase, the proposed framework has been developed and finalized towards its maturity.Findings– Based on the literature, the authors have developed a framework for understanding factors which influence inter-organizational knowledge sharing. Knowledge sharing among organizations appears theoretically sound, but it is a difficult task due to some complexities.Research limitations/implications– This paper attempts to set a theoretical framework for inter-organizational knowledge sharing as a foundation to address the gap in current literature though it does not claim to be comprehensive.Originality/value– A few attempts have been made to investigate success factors for inter-organizational knowledge sharing empirically or even theoretically, but this is the first of its kind that provides a theoretical framework to arrange success factors for the knowledge sharing based on inter-organizational collaborations. It serves as a useful starting point for those interested in knowledge management (KM). So it can serve as a roadmap of significant knowledge sharing research for researchers, designers and managers considering their options for fostering KM.
Integrating Semantic Web technologies with XML Schema using role-mapping annotations
Authors: Hsu I-Ching , Yang Lee Jang , Huang Der-Chen , Lai Kuan-Yang 
Published: May 2014

Purpose
– XML Schema is used to define schema of XML documents that have become standards for data exchange in various Web-based information applications. The main problem of XML Schema is that it emphasizes syntax and format rather than semantics and knowledge representation. Hence, even though having the advantage of describing the structure and constraining the contents of XML documents, XML Schema lacks the computer-interpretability to support knowledge representation for existing information systems. The purpose of this study is to propose role-mapping annotations for XML Schema (RMAXS) to integrate Semantic Web with XML Schema, which allows the facilitation interoperability between adjoining layers of the Semantic Web stack.

Design/methodology/approach
– The XML, XML Schema, ontology, and rule can be completely integrated into a multi-layered intelligent framework (MIF) for XML-based applications in the current web environment. This work presents a semantic-role-mapping intelligent system, called SRMIS, based on the MIF. SRMIS consists of XML-based document repository, search engine, inference engine and transformation engine, which provides different approaches to present the various metadata and knowledge representations.

Findings
– The traditional Semantic Web stack has three gaps between adjoining layers. The first gap, between the XML and XML Schema layers can be bridged with an XMLSchema-instance mechanism. The third gap, between the ontology and rule layers can be connected by building rules on top of ontologies. This study proposes RMAXS to couple the second gap, between the XML schema and ontology layers. The proposed multi-layered intelligent framework (MIF) adopts these coupling technologies to facilitate interoperability between adjoining layers. Therefore, the XML, XML Schema, ontology, and rule can be completely integrated into the MIF for intelligent applications in the web environment.

Practical implications
– To demonstrate the SRMIS applications, this work implements a prototype that helps researchers to find interested papers.

Originality/value
– This work presents a semantic-role-mapping intelligent system, called SRMIS, based on the MIF. SRMIS consists of XML-based document repository, search engine, inference engine and transformation engine, which provides different approaches to present the various metadata and knowledge representations. The proposed SRMIS can be applied in various application domains.
The causal relationships between stock returns, trading volume, and volatility
Authors: Sana Hsieh Hui-Ching 
Published: May 2014

Purpose– The real estate markets in Asia have attracted significant investor attention as they have grown rapidly in recent years. Both local and foreign investors continue to display a strong appetite for Asian real estate investment projects. Given the different characteristics of listed real estate stocks, the purpose of this paper is to focus on the causal relations between the financial variables of these stocks. This financial analysis can help investors to understand the characteristics of listed real estate companies, provide implications for optimal asset allocation decisions, and also increase the predictability of portfolio returns.Design/methodology/approach– In this research, the paper investigates the contemporaneous and causal relations between stock returns, trading volume and volatility in a domestic market context and between different national markets for listed real estate companies in seven Asian economies.Findings– The paper finds that there are positive contemporaneous relations between trading volume and both returns and absolute returns. When the paper examines the causal relations between the financial variables, the evidence implies that current trading volume helps to explain the returns indirectly by leading return volatility; however, trading volume does not help to explain future returns directly. Extending the causality test to international markets, the listed real estate portfolios of the four Southeast Asian countries are found to be more closely correlated than those of the other three countries studied here. Among the four Southeast Asian countries, Singapore, the only developed country, is found to play an influential role, its current financial variables having predictive power for the other countries.Originality/value– This research provides global investors with a better understanding of the Asian listed real estate market, showing that trading volume contains important information regarding returns, that the characteristics of listed real estate companies are closer to those of the financial market than those of the real estate markets, and that the markets of the major economies have extensive influence over the smaller markets. Moreover, given the scarcity of research on the performance of Asian listed real estate companies themselves, this study improves the completeness of the academic literature.
Managing integrated information flow for delivery reliability
Authors: Durugbo Christopher , Tiwari Ashutosh , R. Alcock Jeffrey 
Published: May 2014

Purpose
– The purpose of this paper is to explore the management of information flow for delivery reliability. It analyses how the integration strategies of traceability, transaction costs and vertical integration that shape integrated information flow are managed during delivery processes of firms. While delivery reliability contributes to firm competitiveness, information flow is central to firms interaction internally and externally to facilitate delivery.

Design/methodology/approach
– The paper applies an exploratory multiple-case study involving 21 delivery team members in three industrial technology-based firms. Informed by a multidisciplinary framework from literature, the study captures “what” and “how” existing firms manage information flow during delivery. Individual cases from the company were compared analysed to determine themes that drive delivery-related integrated information flow management.

Findings
– The paper finds that case firms prioritised understanding interaction logics, maintaining process timeliness, review-oriented streamlining and communication-oriented coordination. The study also finds that for delivery reliability in technology-based firms, the interplay of vertical integration, market relations and long term, voluntary relations, especially through the use of small, dedicated and highly skilled team, is required to effectively manage delivery-related integrated information flow.

Originality/value
– The major contribution of this paper is an exposition on practices for facilitating information flow integration. It also offers insights that suggest integrated information flow for delivery reliability could be enhanced through the use of customer-focused communication channels, context-driven documentations, multiple and alternate communication channels as well as intuitive and user-friendly documentation strategies.
Factors affecting online repurchase intention
Authors: Lin Chinho , Lekhawipat Watcharee 
Published: May 2014

Purpose
– The purpose of this paper is to investigate the effects of online shopping experience and habit in relation to adjusted expectations for enhancing online repurchase intention.

Design/methodology/approach
– The authors employed partial least square (PLS) as a technique used to analyze the measurement and structural models. Data for this research were collected from 240 Taiwanese online shoppers who had experienced online shopping at least four times.

Findings
– The result of this study indicates that online shopping habit acts as a moderator of both customer satisfaction and adjusted expectations, whereas online shopping experience can be considered a key driver for customer satisfaction. Furthermore, the research findings confirm that customer satisfaction is a vital driver of adjusted expectations and online repurchase intention. Adjusted expectations do mediate the impact of online repurchase intention.

Research limitations/implications
– This paper highlights the effect of online shopping experience and online shopping habit on enhancing repurchase intention. The result implies that the acquisition of usage experience and spontaneous purchases not only leads to higher customer satisfaction and customer expectations, but also strengthens online repurchase intention. The use of self-report scales suggests the possibility of a common method bias. Future studies may further test the robustness of this study in the interplay of experience and habit to shed more light on their relative importance in explaining online repurchase intention.

Originality/value
– This study extends expectancy-disconfirmation paradigm, especially in the context of online shopping, by emphasizing cognitive, affective, and behavioral change on the attitude-intention behavior of online shoppers.
Proximal and distal influences on project creativity in international marketing teams
Authors: Suh Taewon , Badrinarayanan Vishag 
Published: May 2014

Purpose– The purpose of this paper is to examine the antecedents of project creativity in international marketing teams. The proposed framework includes both proximal (characteristics that impact the everyday functioning of the team) and distal (characteristics associated with the team's organizations that are relatively remote to the everyday functioning of the team) factors as antecedents of project creativity. Specifically, the authors investigate the influence of three proximal factors, namely, collaboration with foreign counterparts, autonomy, and international experience as well as two distal factors, namely, organizational encouragement and innovative organizational culture.Design/methodology/approach– Data were collected from 156 executives from publicly traded firms in the manufacturing sector in South Korea and tested using hierarchical regression.Findings– Collaboration with foreign counterparts and autonomy exert direct positive influence on project creativity. International experience exerts a curvilinear relationship such that low and high levels of international experience positively influence project creativity, whereas moderate international experience negatively influences project creativity. In addition, whereas the relationship between organizational encouragement and project creativity was supported, the relationship between innovative culture and project creativity was not.Originality/value– Despite the importance afforded to international marketing teams and creativity in marketing research and practice, little attention has focussed on project creativity in international marketing teams. This study represents an initial effort toward filling the void and identifying certain proximal and distal factors as relevant antecedents of project creativity in international marketing teams. In addition, deviating from extant studies on creativity, this study highlights a curvilinear relationship between international experience and creativity.
A consensus-based corporate governance paradigm for Islamic banks
Authors: Abdel-Baki Monal , Leone Sciabolazza Valerio 
Published: May 2014

Purpose– Islamic banking is a viable sustainable banking model that has shown resilience to financial crises. The aim of this research is to design a consensus-based ethical and market-driven corporate governance index (CGI) to boost financial performance and ensure compliance with Islamic rulings.Design/methodology/approach– The design of the CGI is the outcome of the feedback obtained from a cross-country survey to measure bank efforts in enhancing corporate governance (CG) throughout the ten-year period of 2001-2011. The CGI is divided into six core CG themes and 40 sub-themes.Findings– First, the results of the multiple regression analysis show a consistent positive relationship between CG and financial performance metrics. Second, the authors detect misaligned compensation structures for directors. Third, poor governance leads to higher risk exposures.Research limitations/implications– CG in Islamic banks is yet an evolving discipline and infant practice. This research aims to introduce a CGI that should be updated and improved as the discipline evolves.Practical implications– The research concludes by proposing a CG paradigm. The outcome of the research could also be of use to both Islamic banks and to the rapidly growing sustainable banking sector in designing a similar CGI and CG model incorporating the ethical features of sustainable finance.Social implications– The core ethos of Islam are: avoiding the exploitation of the needy, avoiding excessively risky transactions, avoiding unethical transactions and justice, equity and income redistribution. If properly applied, Islamic banking will display all features of sustainable finance as well as enhance social welfare.Originality/value– To the best of the authors' knowledge, this is the first CGI that is based on an ethical and all-inclusive input of all stakeholders.
Smaller university endowments: team characteristics, portfolio composition and performance
Authors: Lord Mimi 
Published: May 2014

Purpose
– The paper aims to help explain how certain smaller university endowments are able to provide investment results that are more typical of much larger endowments. Investment teams' characteristics and risk-reward perceptions are examined in relation to portfolio composition and performance.

Design/methodology/approach
– This exploratory study uses a grounded-theory approach consisting of 20 in-depth interviews of financial officers at US colleges and universities with assets between $100 million and $200 million. Ten were conducted from the top performance quartile and ten from the bottom quartile. Interviews were transcribed and coded; afterward, emerging themes and constructs were identified. Objective investment performance over a ten-year period was employed from a well-known industry survey.

Findings
– Top-performing endowments were described as having endowment teams with greater investment expertise, efficacy, decision-making independence and learning commitment than teams from the low-performing endowments. Teams from top-performing endowments assessed alternative investments more favorably and made greater portfolio allocations to them as compared to teams from low-performing endowments.

Research limitations/implications
– Because of the chosen research approach, the research results may not be generalizable.

Practical implications
– The paper includes implications for colleges and universities in the management of their endowments, and particularly in the selection of committee and other team members.

Originality/value
– The paper is original in exploring certain team characteristics and practices of institutional investment decision-makers and their relationship to portfolio composition and performance.

Recent introduction of an allodapine bee into Fiji: A new model system for understanding biological invasions by pollinators
Authors: Groom Scott V. C. , Tuiwawa Marika V. , Stevens Mark I. , Schwarz Michael P. 
Published: May 2014

AbstractMorphology‐based studies have suggested a very depauperate bee fauna for islands in the South West Pacific, and recent genetic studies since have indicated an even smaller endemic fauna with many bee species in this region resulting from human‐aided dispersal. These introduced species have the potential to both disrupt native pollinator suites as well as augment crop pollination, but for most species the timings of introduction are unknown. We examined the distribution and nesting biology of the long‐tongued beeBraunsapis puangensisthat was first recorded from Fiji in 2007. This bee has now become widespread in Fiji and both its local abundance and geographical range are likely to increase dramatically. The impacts of this invasion are potentially enormous for agriculture and native ecosystems, but they also provide opportunities for understanding how social insect species adapt to new environments. We outline the major issues associated with this recent invasion and argue that a long‐term monitoring study is needed.
