Effective keyword query processing with an extended answer structure in large graph databases
Authors: Park Chang-Sup , Lim Sungchae 
Published: April 2014

Purpose
– The paper aims to propose an effective method to process keyword-based queries over graph-structured databases which are widely used in various applications such as XML, semantic web, and social network services. To satisfy users' information need, it proposes an extended answer structure for keyword queries, inverted list indexes on keywords and nodes, and query processing algorithms exploiting the inverted lists. The study aims to provide more effective and relevant answers to a given query than the previous approaches in an efficient way.

Design/methodology/approach
– A new relevance measure for nodes to a given keyword query is defined in the paper and according to the relevance metric, a new answer tree structure is proposed which has no constraint on the number of keyword nodes chosen for each query keyword. For efficient query processing, an inverted list-style index is suggested which pre-computes connectivity and relevance information on the nodes in the graph. Then, a query processing algorithm based on the pre-constructed inverted lists is designed, which aggregates list entries for each graph node relevant to given keywords and identifies top-k root nodes of answer trees most relevant to the given query. The basic search method is also enhanced by using extend inverted lists which store additional relevance information of the related entries in the lists in order to estimate the relevance score of a node more closely and to find top-k answers more efficiently.

Findings
– Experiments with real datasets and various test queries were conducted for evaluating effectiveness and performance of the proposed methods in comparison with one of the previous approaches. The experimental results show that the proposed methods with an extended answer structure produce more effective top-k results than the compared previous method for most of the queries, especially for those with OR semantics. An extended inverted list and enhanced search algorithm are shown to achieve much improvement on the execution performance compared to the basic search method.

Originality/value
– This paper proposes a new extended answer structure and query processing scheme for keyword queries on graph databases which can satisfy the users' information need represented by a keyword set having various semantics.
Towards an understanding of real-time continuous feedback from simulation games
Authors: Nkhoma Mathews , Calbeto Jaime , Sriratanaviriyakul Narumon , Muang Thu , Ha Tran Quyen , Kim Cao Thanh 
Published: April 2014

Purpose
– Simulation games have long been used as a teaching tool in the classroom environment mainly due to the high level of participation and engagement that students are able to generate from these, making the learning process more enjoyable and capable to replicate real-life scenarios. Feedback given during the simulation helps to motivate students to find better solutions to the problems being presented in the games and thus enhance their hands-on knowledge on particular subjects. The purpose of this research is to provide empirical evidence of interrelations and impacts that exist between real-time continuous feedback and simulation game performance as well as the interrelations and impacts that exist between real-time continuous feedback and both students' attitude and engagement towards learning.

Design/methodology/approach
– The research focused on 60 undergraduate students enrolled at the Centre of Commerce at RMIT University Vietnam who had taken at least three semesters at various programmes. For test purposes, the research employed a 3D IBM business process management (BPM) simulation game, INNOV8 developed by the IBM Academic Initiative (more information about the game is available at: www-01.ibm.com/software/solutions/soa/innov8/index.html). A web-based survey followed at the university grounds for the collection of data.

Findings
– Students showed a favourable attitude towards learning through the simulation game. In addition, the real-time continuous feedback given during the simulation game had a positive impact on the students' cognitive learning outcomes.

Research limitations/implications
– The sample size used was relatively small with 60 participants, most unfamiliar with the theories of BPM.

Originality/value
– The originality of this research stems from the real-time and continuous nature of the feedback being given to students during the gameplay of a computer-based simulation game, and how this type of feedback could positively impact the students' learning outcomes.
Making the point? The audiovisual/digital media dissertation
Authors: Houtman Coral , Thomas Maureen , Barrett Jennifer 
Published: April 2014

Purpose– The purpose of this paper is to address the advantages of education and training in creating the “Audiovisual/Digital Media Essay” (AV/DME), starting from visual and cinematic thinking as a way of setting up, developing and concluding an argument.Design/methodology/approach– Recognising the advantages to education and training of the “AV/DME” this paper explores ways of enabling visually disciplined students to work on film theory within their chosen medium, and to develop arguments incorporating audiovisual sources, using appropriate academic skills. It describes a hands-on BA/MA workshop held at Newport Film School (May 2011) and subsequent initial implementation of an examinable DME. The paper contextualises the issue in the light of practice-led and practice-based research and of parity with written dissertations. Drawing on analysis of in-depth interviews with students and tutors, it makes practical recommendations for how to resource, staff and support the implementation and continuation of the AV/DME and/or dissertation.Findings– The paper feeds back from both students and staff on the running of an initial AV/DME workshop and finds that the Film School Newport is suited to running the AV/DME and suggests a framework for its support.Research limitations/implications– The study needs to be followed up when the students complete their full dissertations.Practical implications– The AV/DME needs sufficient technical and human resources to support student learning.Originality/value– The paper provides a clear and original framework for teaching, supporting and assessing the AV/DME. This framework can be disseminated beyond the University of Wales Newport, and can be used to teach the AV/DME in further contexts and to wider groups of students.
Correlates of academic misconduct and CSR proclivity of students
Authors: K. Nkundabanyanga Stephen , Omagor Charles , Nalukenge Irene 
Published: April 2014

Purpose– The purpose of this paper is to examine the effect of the fraud triangle, Machiavellianism, academic misconduct and corporate social responsibility (CSR) proclivity of students.Design/methodology/approach– The present study surveyed 471 university students. The study was cross-sectional and employed structural equation modelling in statistical modelling.Findings– The study provides evidence that perceived opportunity to cheat in examinations is the single most important factor accounting for significant variations in rationalization and academic misconduct. Similarly, low Machiavellians significantly get inclined to CSR ideals. The fraud triangle alone accounts for 36 per cent of the variations in academic misconduct, hence the error variance is 64 per cent of academic misconduct itself. This error variance increases to 78 per cent when a combination of perceived opportunity, rationalization, Machiavellianism is considered. Moreover, both Machiavellianism and academic misconduct account for 17 per cent of variations in students’ proclivity to CSR ideals.Research limitations/implications– Results imply that creating a setting that significantly increases a student's anticipated negative affect from academic misconduct, or effectively impedes rationalization ex ante, might prevent some students from academic misconduct in the first place and then they will become good African corporate citizens. Nevertheless, although the unit of analysis was students, these were from a single university – something akin to a case study. The quantitative results should therefore be interpreted with this shortcoming in mind.Originality/value– This paper contributes to the search for predictors of academic misconduct in the African setting and as a corollary, for a theory explaining academic misconduct. Those students perceiving opportunity to cheat in examinations are also able to rationalize and hence engage in academic misconduct. This rationalization is enhanced or reduced through Machiavellianism.
Facilitating embodied learning in business ethics education: the use of relational sculpting
Authors: Simola Sheldene 
Published: April 2014

Purpose– The purpose of this paper is to first, provide an interdisciplinary overview of the pedagogical perspective known as “embodied learning”; second, describe the particular relevance of embodied perspectives for business ethics and business ethics education; third, introduce “relational sculpting” as a pertinent embodied technique in this context.Design/methodology/approach– Content analysis of qualitative data on relational sculpting fromn=50 participants in two sections of a required undergraduate course on business ethics was conducted.Findings– Findings indicated that the use of relational sculpting was associated with increased emotional awareness of, and empathy for stakeholders; a more compelling sense of connection to ethical issues and the affected stakeholders; enhanced understanding of stakeholder perspectives; and, a stronger appreciation of interconnections among stakeholders, as well as of the situation as a whole.Research limitations/implications– Future investigations could explore diverse other applications of relational sculpting and any implications these might have for learning effectiveness. Consideration could also be given to the viability, development, implementation and assessment not just of embodied techniques, but also, of integrated and coherent educationalprogramsthat are embodied in nature.Practical implications– Step-by-step practical guidelines for using relational sculpting are provided. Additionally, comprehensive ethical guidelines for the use of innovative teaching methodologies such as relational sculpting are also provided.Originality/value– Management scholars have recently advocated not only for increased ethics training in undergraduate and graduate curricula, but also for enhanced teaching and learning through the integration of diverse scholarly perspectives and innovations. This paper provides an interdisciplinary overview of the pedagogical perspective known as “embodied learning,” identifies its relevance for business ethics and business ethics education, and also introduces “relational sculpting” as a relevant embodied technique.
A review and critique of content analysis as a methodology for inquiring into IC disclosure
Authors: Dumay John , Cai Linlin 
Published: April 2014

Purpose
– The purpose of this paper is to review and critique the current status of content analysis (CA) as a research method for inquiring into intellectual capital disclosure (ICD) to determine if CA has a continued role to play in developing new intellectual capital (IC) knowledge.

Design/methodology/approach
– In all, 110 articles utilising CA as a research methodology for inquiring into ICD are analysed. The research is developed in line with other articles critically investigating IC research conducted by Guthrie et al. (2012), Dumay and Garanina (2013) and Dumay (2014). To help understand the impact of CA research articles, the data set is supplemented by including citation data from Google Scholar. The authors also differentiate the paper from other IC research reviews by critically examining the findings and implications of the articles analysed.

Findings
– The authors do not hold a very positive view on future research which does not substantially depart from the plethora of articles examining ICD using annual reports as a data source or who do not in some way radically change the approach. The authors are of the view that early research into ICD using CA as a methodology was warranted because there was little knowledge about the pattern of IC disclosure in annual reports and other possible ICD forms. However, the research into ICD using annual reports and other data sources has added little more than prove that companies are unwilling to publicly disclose IC to their stakeholders. While the authors do not hold a positive view on future CA research based on annual reports, the authors do hold out hope that researchers will transform their understanding and application of CA as a research methodology and offer one example of how this might be achieved.

Originality/value
– The paper presents a comprehensive critical review of published articles utilising CA as a research methodology for inquiring into ICD along with measuring the impact of the articles using citation data from Google Scholar. Hence, the research and its impacts are simultaneously assessed offering insights into the future role that CA as a research methodology has to play in developing new IC knowledge.
Innovative ways companies are using design thinking
Authors: Liedtka Jeanne 
Published: April 2014

Purpose
– Researchers at the University of Virginia's Darden Business School and the Design Management Institute report on field research into how widely design thinking is being adopted in leading companies and how effectively is it being adapted in a variety of industries.

Design/methodology/approach
– They interviewed boundary spanners – leaders who operated at the intersection of design and business – in a number of Fortune 100 organizations and focused on ten organizations where design thinking was having an impact on practice.

Findings
– They found that design thinking was, in fact, also a problem solving process, not just an innovation process.

Research limitations/implications
– Examples are anecdotal.

Practical implications
– Learning from design tools – such as, ethnographic interviewing, customer journey mapping and job-to-be-done analysis – encouraged team members to stay involved with the problem long enough to reframe the opportunity.

Originality/value
– The highest payoff from adopting a design-thinking approach was not necessarily in identifying a solution, but rather in innovating how people worked together to envision and implement the new possibilities they discovered.
How to plan and manage a project to co-create value with stakeholders
Authors: Bhalla Gaurav 
Published: April 2014

Purpose
– The article explains how innovating with customers and other stakeholders to achieve co-creation of value requires companies to marry their collaborators' interests with corporate knowledge and resources. The process starts with setting objectives and proceeds through four additional steps: selection of arenas, engagement with collaborators, choice of project tools and processes and defining contracts with stakeholders.

Design/methodology/approach
– The authors describe how leading firms have developed best-practice processes, tools and technologies to better enable and expedite value co-creation.

Findings
– The article offers managers guidelines for deciding which customers to select for participation in specific co-creation programs. The choices are: Customers who have extraordinary passion for their brands; customers in attractive or untapped market segments; customers that exhibit a high co-creation potential; innovators and early adopters; lead users looking to develop solutions to solve their own needs.

Practical implications
– Collaborative innovation projects need to define “What's in it for the collaborators?” Customer collaboration rarely operates independent of incentives.

Originality/value
– The article offers practical guidance for companies that engage in co-creation projects because they want to them to foster the discovery of customer interest and value, which they can turn into innovation and competitive advantage.

Published: April 2014

AbstractAimThe dramatic rise in childhood obesity incidence in developing countries is related to nutrition and lifestyle transition. The aim of this review was to evaluate the quality and reporting of dietary assessment methods used in studies examining the relationship between dietary outcome and childhood obesity in developing Asian countries.MethodsA three‐step search strategy was conducted in databases between inception and 2011 with an English language restriction. Inclusion criteria were any cross‐sectional or cohort studies in children ≤18 years who resided in developing countries in Asian region that included reporting on dietary intake. Papers were screened with standardised tools for quality and dietary methodology reporting.ResultsThe search process identified 2080 studies and 15 studies (in 16 articles) met inclusion criteria. The most commonly used dietary assessment method was dietary questionnaires (n = 10), followed by 24‐hour diet recall (n = 4), food frequency questionnaire (n = 3) and an unweighed food record (n = 1). For dietary methodology reporting, 12 out of 16 articles were rated as ‘poor’, 3 rated as ‘acceptable’ and 1 as ‘excellent’.ConclusionsThe quality rating was influenced by the dietary assessment tool chosen, and a quality rating of ‘poor’ was mostly obtained by studies using non‐standardised, non‐validated study‐specific dietary questionnaires. Significant gaps were identified in dietary intake methodological quality and hence, there is an urgent need for valid dietary measures and reporting of dietary intake among overweight children for studies conducted in Asian region.
Recovery Effect of Onion Peel Extract against H2O2‐Induced Inhibition of Gap‐Junctional Intercellular Communication is Mediated through Quercetin

Published: April 2014

AbstractCellular oxidative damage mediated by reactive oxygen species has been reported to inhibit gap‐junctional intercellular communication (GJIC). In turn, the inhibition of GJIC can be attenuated by functional food compounds with antioxidant properties. In this study, we compared the protective effects of onion peel extract (OPE) and onion flesh extract (OFE) on oxidative stress‐mediated GJIC inhibition, and investigated the mechanisms of action responsible. OPE restored H2O2‐induced GJIC inhibition to a higher degree than OFE in WB‐F344 rat liver epithelial cells. OPE was found to inhibit H2O2‐induced phosphorylation of ERK1/2 and Cx43. A radical scavenging assay demonstrated superiority of OPE over OFE, suggesting that the observed effects might be mediated via an antioxidant mechanism. Quercetin is the major compound that is likely to be responsible for the protective effect against H2O2‐mediated GJIC inhibition. This study suggests that OPE, a material often discarded, may be of value for the future development of functional food products.Practical ApplicationThis study demonstrates that onion peel extract (OPE) exhibits a protective effect against the inhibition of gap‐junctional intercellular communication (GJIC) mediated by H2O2, which is likely to occur via its antioxidant activity. OPE contains significant concentrations of bioactive phenolic compounds. Reductions in oxidative stress can lead to recovery of GJIC, which has been reported to be implicated in the prevention and treatment of cancers. These findings suggest that onion peel, a common waste product, could be used as potential resources for functional food development. Onion peel could be processed into a quercetin‐rich powder or a pill for the prevention of cancer and other oxidative stress‐related diseases.
Effect of Genotype and Environment on the Glycoalkaloid Content of Rare, Heritage, and Commercial Potato Varieties
Authors: Valcarcel Jesus , Reilly Kim , Gaffney Michael , O'Brien Nora 
Published: April 2014

AbstractPotatoes accumulate toxic steroidal compounds that could be harmful for humans if consumed in high quantities and must be controlled. In this study, we were interested in assessing the levels and variation of glycoalkaloid content in 60 varieties of potato planted in 2 trial sites over 2 y. Total glycoalkaloid levels ranged from 4 to 957 mg/kg of dry weight in the flesh and from 150 to 8133 mg/kg in the skin, with the latter accumulating generally more α‐chaconine than α‐solanine. Contents in the flesh were below the safe limit for all varieties, but were generally above in the skin. Maximum values in each site and year of cultivation were found for varieties “Beauty of Hebron,” “May Queen,” and “Arran Pilot” in the skin and “Beauty of Hebron,” “International Kidney,” and “Congo” in the flesh. Year of cultivation had a significant effect on total glycoalkaloid content (P < 0.0001), with interactions between variety and site of cultivation and variety and year of cultivation also significant (P < 0.0001), implying that environmental effects seem to act differentially and could induce high levels in genetically predisposed varieties.Practical ApplicationThis paper reports the levels of toxic glycoalkaloids in 60 varieties of potato. Dietary intake and safety of consumers is discussed and varieties used by the potato processing industry are assessed in terms of safety and potential use of waste peel as raw material.
Electrolytic echo enhancement: A novel method to make needles more reflective to ultrasound
Authors: Cockburn John F. , Khosh Stefan K. 
Published: April 2014

AbstractIntroductionThis study examines the effect of augmenting the ultrasound reflectivity of needles using a novel electrolytic echo enhancement method.MethodsNeedles were connected by a lead to the negative terminal of a 4.5 V direct current source. A grounding pad, connected to the positive terminal, was positioned on the undersurface of an ex vivo ox liver phantom. During needle insertion into the liver, electrolysis was induced creating a layer of gas on the needle electrode.ResultsAnalysis of images showed a significant increase in needle brightness using electrolytic echo enhancement. Brightness was found to increase by a factor of ×3.6 compared with controls (P < 0.001).ConclusionElectrolytic echo enhancement has the potential to make ultrasound‐guided procedures safer and quicker for patients and increase the confidence of operators in their ability to see the whole needle including its tip.
