Authors: Costa Andreu F. , Tremblay St-Germain Amélie , Abdolell Mohamed , Smoot Rory L. , Cleary Sean , Jhaveri Kartik S. 
Published: November 2017

Objective
The objective of this study was to assess the accuracy of gadoxetic acid hepatic enhancement indices in predicting posthepatectomy liver failure (PHLF) and other major complications (OMCs).

Methods
Sixty-five patients underwent prehepatectomy gadoxetic acid–enhanced magnetic resonance imaging. Enhancement indices were calculated by obtaining regions of interest on magnetic resonance images and segmented volumes of the liver and spleen. Multivariate regression analysis was performed to predict PHLF and OMC as a function of the indices, and areas under the receiver operator characteristic (AUROC) curves were calculated.

Results
Areas under the receiver operator characteristic values varied from 0.412 to 0.681 and 0.462 to 0.738 in predicting PHLF and OMC, respectively. The most accurate indices in predicting PHLF were the region of interest–based, fat-normalized relative liver enhancement and liver enhancement index (AUROC, 0.681). The most accurate index in predicting OMC was the volumetric least-squares regression slope of a pharmacokinetic model (K
hep_V, AUROC, 0.738).

Conclusions
Indices of gadoxetic acid liver enhancement demonstrate variable performance in predicting PHLF and OMC.

Authors: Zheng Lichun , Xing Haiqun , Li Fang , Huo Li 
Published: November 2017

Abstract
Autoimmune pancreatitis generally results in diffuse increased FDG activity throughout the pancreas on PET/CT images. We present a case of focal autoimmune pancreatitis with abnormal FDG activity involving only the pancreatic tail on PET/CT in a 61-year-old man who was provisionally diagnosed as having pancreatic cancer based on the CT findings. The diagnosis of autoimmune pancreatitis was based on pathological examination and elevated serum immunoglobulin G4 level. Following the steroid therapy, the patient was gradually recovered.
Yin-yang dialectics and communitarianism in cross-cultural management research
Authors: Chen Chao C. 
Published: November 2017

PurposeThe purpose of this paper is to comment on “Global implication of the indigenous epistemological system from the East: How to Apply yin-yang balancing to paradox management” by Li (2016). As a pioneer in developing indigenous Chinese management theories, Li has been focused on extracting essential principles of the Chinese yin-yang philosophy and applying them to organization and management phenomena within and outside China (Li, 1998, 2012, 2014a, b). In this paper (Li, 2016), Li sharpens his thinking on the unique attributes of the Chinese yin-yang balancing perspective so as to both distinguish it from and connect it to Western Aristotelian and Hegelian philosophies in regard to contradictions and paradoxes that are increasingly more prevalent in contemporary organizations. The author found Li’s paper thought provoking and highly relevant to cross-cultural management research. The author reflects on the yin and yang of the yin-yang perspective itself and discusses how it can be extended for theorizing about cross-cultural or inter-cultural management research.Design/methodology/approachApplying yin-yang dialectics on the East-West cultural differences, this commentary contends that the strengths and weaknesses of the cultural mindsets of the East and the West are relative and potentially complementary to each other, and seeks to balance and integrate Eastern and Western perspectives for theorizing and tackling cultural differences and conflicts in a globalized world.FindingsOn the basis of yin-yang dialectics on cultural differences, a communitarianism model is proposed for cross-cultural researchers to balance and integrate individualism and collectivism, a well-established East-West cultural difference.Originality/valueThe theoretical model of communitarianism builds upon but transcends either Eastern or Western cultural differences toward a viable global value system.
Student learning opportunities in traditional and computer-mediated internships
Authors: Bayerlein Leopold , Jeske Debora 
Published: November 2017

Purpose
The purpose of this paper is to provide a student learning outcome focussed assessment of the benefits and limitations of traditional internships, e-internships, and simulated internships to evaluate the potential of computer-mediated internships (CMIs) (e-internships and simulated internships) within higher education from a student perspective.

Design/methodology/approach
The paper undertakes a systematic conceptually based assessment of the extent to which CMIs are able to replicate the cognitive, skill-based and affective learning outcomes of traditional internships. In addition, the key limitations of traditional internships from a student perspective are identified, and the potential ability of CMIs to address these limitations is assessed.

Findings
The findings of this paper highlight that CMIs are able to replicate most of the benefits of traditional internships, whilst concurrently addressing many of their limitations. However, the current paper also identifies a number of important limitations for student learning in CMIs, and provides advice that aims to assist students in maximising their learning outcomes in these situations.

Originality/value
The paper is the first to provide a systematic student learning outcome focussed comparison of traditional internships and CMIs. In addition, the paper establishes the high potential of simulated internships for student learning in higher education, and provides students, higher education providers and researcher with learning outcome focussed criteria sets that enable the empirical evaluation of CMIs in future research.
A novel technique for modeling friction behavior in knitted fabric simulation
Authors: Mozafary Vajiha , Payvandy Pedram 
Published: November 2017

Purpose
Fabric-object friction force is a fundamental factor in cloth simulation. A large number of parameters influence the frictional properties of fabrics such as fabric structure, yarn structure, and inherent properties of component fibers. The purpose of this paper is to propose a novel technique for modeling fabric-object friction force in knitted fabric simulation based on the mass spring model.

Design/methodology/approach
In this technique, unlike other studies, distribution of friction coefficient over the fabric surface is not uniform and depends on the fabric structure. The main reason for considering non-uniform distribution is that in various segments of fabric, contact percent of fabric-object is different.

Findings
The proposed technique and common methods based on friction coefficient uniform distribution are used to simulate the frictional behavior of knitted fabrics. The results show that simulation error values for proposed technique and common methods are 2.7 and 9.4 percent as compared with the experimental result, respectively.

Originality/value
In the existing methods of the friction force modeling, the friction coefficient of fabric is assumed uniform. But this assumption is not correct because fabric does not have an isotropic structure. Thus in this study, the friction coefficient distribution is considered based on fabric structure to achieve more of realistic simulations.
Developing the C-shaped QFD 3D Matrix for service applications with a case study in banking services
Authors: Shahin Arash , Bagheri Iraj Elham , Vaez Shahrestani Hossein 
Published: November 2017

Purpose
The purpose of this paper is to develop the C-shaped quality function deployment (QFD) 3D Matrix for service applications.

Design/methodology/approach
The C-shaped QFD 3D Matrix proposed by Vezzetti et al. (2016) has been developed for simultaneous analysis of the relationships among three sets of factors of customer requirements, service design characteristics and service performance indicators. The three sets of factors have been determined and based on their interrelationships, 3D and concurrent houses of quality have been formed. Then, service design characteristics and service performance indicators have been prioritized. The obtained priorities have been also compared with traditional concurrent model of QFD.

Findings
The findings obtained from the traditional and developed approach seem different, implying that applying the C-shaped QFD 3D Matrix provides a more real perspective of concurrent engineering and the results in different set of priorities of service factors.

Research limitations/implications
The case study was limited to banking services. If the developed approach is used in other institutes, the prioritization of service design characteristics and service performance indicators might be changed.

Originality/value
Compared to Vezzetti et al. (2016) who proposed the C-shaped QFD 3D Matrix for analyzing interrelationships among two customers and a provider, or two providers and a customer, in this paper, the C-shaped QFD 3D Matrix has been developed for analyzing interrelationships among three sets of factors of customer requirements, service design characteristics and service performance indicators.
Optimization of repairable systems with repairman’s multiple vacations
Authors: Yedida Sarada , R. Shenbagam 
Published: November 2017

PurposeTechnological advancements and growing complexity of many real-time systems, namely, communication, transportation, defense systems, etc., necessitate the importance to adopt a well-planned repair process such as phase type quasi-renewal process contributing to an improved system performance. Further, in an attempt to boost the role of maintenance as a financial benefactor, repairman’s multiple vacation policy is incorporated. Also, the significance of the degree of repair is illustrated while indicating the suitability of the matrix-analytic approach via the phase type quasi-renewal operating/repair times in reliability. The paper aims to discuss these issues.Design/methodology/approachThe optimal replacement policy is obtained by employing the matrix-analytic method and minimum average cost rate.FindingsThe considered models make a significant contribution towards establishing that the matrix-analytic method, using the phase type quasi-renewal process, aids in reducing the computations and also fills the gap in the literature in the study of deteriorating systems. Availability and rate of occurrence of failures are evaluated in transient and steady-state regime.Originality/valueThis model differs from the existing models, in that, a repairman’s multiple vacation, delayed repair time and representation of the failure occurrence by a mixed Poisson process have been incorporated into the analysis. Also, time-dependent case and N-policy have been adopted to explore the optimality issues using phase type quasi-renewal process analytically. The numerical illustrations warrant that the maintenance policy proposed in this paper produces a considerably lower cost.
Enriching and enhancing moving images with Linked Data
Authors: Gracy Karen F. 
Published: November 2017

PurposeThe purpose of this paper is to examine the current state of Linked Data (LD) in archival moving image description, and propose ways in which current metadata records can be enriched and enhanced by interlinking such metadata with relevant information found in other data sets.Design/methodology/approachSeveral possible metadata models for moving image production and archiving are considered, including models from records management, digital curation, and the recent BIBFRAME AV Modeling Study. This research also explores how mappings between archival moving image records and relevant external data sources might be drawn, and what gaps exist between current vocabularies and what is needed to record and make accessible the full lifecycle of archiving through production, use, and reuse.FindingsThe author notes several major impediments to implementation of LD for archival moving images. The various pieces of information about creators, places, and events found in moving image records are not easily connected to relevant information in other sources because they are often not semantically defined within the record and can be hidden in unstructured fields. Libraries, archives, and museums must work on aligning the various vocabularies and schemas of potential value for archival moving image description to enable interlinking between vocabularies currently in use and those which are used by external data sets. Alignment of vocabularies is often complicated by mismatches in granularity between vocabularies.Research limitations/implicationsThe focus is on how these models inform functional requirements for access and other archival activities, and how the field might benefit from having a common metadata model for critical archival descriptive activities.Practical implicationsBy having a shared model, archivists may more easily align current vocabularies and develop new vocabularies and schemas to address the needs of moving image data creators and scholars.Originality/valueMoving image archives, like other cultural institutions with significant heritage holdings, can benefit tremendously from investing in the semantic definition of information found in their information databases. While commercial entities such as search engines and data providers have already embraced the opportunities that semantic search provides for resource discovery, most non-commercial entities are just beginning to do so. Thus, this research addresses the benefits and challenges of enriching and enhancing archival moving image records with semantically defined information via LD.
Emerging adulthood, sharing utilities and intention to use sharing services
Authors: Oyedele Adesegun , Simpson Penny 
Published: November 2017

PurposeThis study aims to test Lamberton and Rose’s (2012) commercial sharing utility model of access-based consumption use in three different contexts: car-sharing, room-sharing and household goods purchases. More importantly, this research extends the model by examining the effects of emerging adulthood as a life-stage on perceived value of social applications that facilitate and promote transaction utility, called shareaids.Design/methodology/approachA questionnaire designed to evaluate the effects of emerging adulthood and sharing utilities on intention to use sharing services was developed and administered to 345 respondents at a Midwestern US university. The data were analyzed using partial least squares structural equation modeling.FindingsResults indicate that flexibility utility had the strongest direct impact on intention to use sharing consumption while also having indirect effects in all contexts examined. The emerging adulthood life-stage was found to affect transaction utility and shareaids as predicted, and shareaids positively influenced consumers’ perception of the social utility value of access-based consumption.Research limitations/implicationsThe generalizability of this study is limited by its use of a student sample. Also, the study suffers from inherent limitations linked to self-reported survey research.Practical implicationsSharing services that have a strong social component could use shareaids to gain a competitive advantage. Examples of shareaid application include split bills for multiple payments to split fares among friends and social media transaction tools. Shareaid applications can enhance consumers’ perception of social value and the overall shareability value of the sharing service.Originality/valueThis is the first known study to test the effects of emerging adulthood as a life-stage on perceived value of social applications that facilitate and promote transaction utility, called shareaids.
A multi-region input-output model for optimizing virtual water trade flows in agricultural crop production
Authors: Aviso Kathleen B. , Holaysan Sed Anderson K. , B. Promentilla Michael Angelo , S. Yu Krista Danielle , R. Tan Raymond 
Published: November 2017

Purpose
The onset of climate change is expected to result in variations in weather patterns which can exacerbate water scarcity issues. This can potentially impact the economic productivity of nations as economic activities are highly dependent on water especially for agricultural countries. In response to this, the concepts of virtual water and water footprint have been introduced as metrics for measuring the water intensity of products, services and nations. Researchers have thus looked into virtual water trade flows as a potential strategy for alleviating water scarcity. The paper aims to discuss these issues.

Design/methodology/approach
Environmentally extended input-output models (IOMs) are often used to analyze interactions between economic and ecological systems. This work thus develops a multi-regional input-output model for optimizing virtual water trade between different geographic regions in consideration of local environmental resource constraints, product demands and economic productivity.

Findings
A case study on agriculture crop production and trade in different regions of the Philippines is utilized to demonstrate the capabilities of the model. The results show that the optimal strategy does not necessarily limit a water-scarce region to produce less water-intensive crops.

Research limitations/implications
The model uses an input-output framework whose fixed coefficients reflect a fixed technological state. As such, the model is best used for short-term projections, or projections for mature technological state (i.e. where no major gains in efficiency or yield can be foreseen).

Practical implications
The proposed modeling framework can be used in any geographic region (provided relevant statistical data are available for calibration) to provide decision support for optimal use of limited water resources.

Originality/value
The model proposed in this work has general applicability to the optimal planning of agro-industrial systems under water footprint constraints. This modeling approach will be particularly valuable in the future, as climate change causes changes in precipitation patterns and water availability.
An overview of environmental management in the Spanish food sector: a survey study
Authors: Ormazabal Marta , Viles Elisabeth , Santos Javier , Jaca Carmen 
Published: November 2017

Purpose
Environmental management (EM) is becoming increasingly important in all types of organizations. The food industry represents the top industrial sector of the Spanish economy; however, there is still little knowledge about how it is managed environmentally. The purpose of this paper is to present a descriptive analysis of the Spanish food sector.

Design/methodology/approach
This study undertook a descriptive analysis based on probabilistic sampling surveys from food companies in Spain. The survey was sent out to 900 companies obtaining 128 answers.

Findings
The results of this study show that companies with an EM standard tend to have a more developed system and a greater presence of EM tools and actions. Moreover, statistical differences were identified among the characteristics of companies and various factors that affect the evolution of their EM.

Originality/value
There are no studies that reveal a clear picture of the status of EM in the Spanish food industry. This study presents a clear starting point that might help policy makers, consultants, researchers and other parties to set new improvement routes so companies do not get stuck in their progress toward environmental excellence.
Chemical characterization and assessment of surface waters’ suitability for irrigation in the mid-Seybouse wadi plain (North-Eastern Algeria)
Authors: Mouassa Souad , Chaab Salah , Moulla Adnane Souffi , Zaagane Mansour , Brahmia Nabil 
Published: November 2017

Purpose
The present study is undertaken in the region of Guelma that is located in North-Eastern Algeria. Guelma’s agricultural plain is irrigated from the Seybouse ephemeral river (wadi). The latter collects the entire domestic and industrial wastewaters of the region that are discharged without prior treatment. Hence, the organic and biological or what so ever contributions to the wadi are capable of initiating a significant degradation of its waters’ quality and challenging their use for irrigation. The paper aims to discuss these issues.

Design/methodology/approach
The interpretation of the results of three sampling campaigns for chemical and bacteriological analyzes was carried out in terms of the indices’ method (organic pollution index (OPI) and microbiological quality index (MQI)). The results were statistically assessed through the use of the principal component analysis (PCA). The OPI was calculated according to the method of Leclercq and Maquet (1987) whose principle is to classify the contents for the polluting elements into 5 classes each class corresponding to a given range for the considered parameter, and then to calculate the overall average class number for each sample. The MQI depends on the water concentrations in: the total coliforms, the fecal coliforms, and fecal streptococci. One defines five classes of concentrations for each of these parameters. The MQI is again the overall mean of the numbers for the classes for every parameter.

Findings
The OPI reflects a moderate pollution for most sampling stations. The PCA indicates that the variables controlling salinity are mainly Cl−, Na+ and SO42−. In August 2016, El-Fedjoudj pumping station shows a very strong fecal contamination. According to the recommendations of World Health Organization (1989), waters from wadi Seybouse cannot be used for the irrigation of vegetable crops if they were to be consumed raw.

Originality/value
This study has an environment impact as it reveals the need to protect surface waters used for irrigation and therefore protect consumers of raw vegetables that are to be consumed uncooked.
Ageing, gender politics and masculinities: reflections on collective memory work with older men
Authors: Blake Vic , Hearn Jeff , Jackson David , Barber Randy , Johnson Richard , Luczynski Zbyszek 
Published: November 2017

Purpose
The purpose of this paper is to reflect on the process of participating in a long-term collective memory work group of older men, focusing on the making/unmaking of older men and masculinities, and the potential of memory work with older men.

Design/methodology/approach
Participant review and reflection on collective memory work with a group of older men.

Findings
Collective memory work provides a novel way to explore ageing, gendering, men, and masculinities. Its potential for working with older men is examined critically in relation to gender politics, power and (in)equalities, interconnections and contradictions of men’s ageing and gendering, the personal and the political, as well as working with older men more generally, including those in transition and crisis.

Originality/value
There is little previous writing on this approach to ageing, men, and masculinities. The paper aims to stimulate wider applications of this approach.
