Digital dark matter within product service systems
Authors: Vendrell-Herrero Ferran , Myrthianos Vasileios , Parry Glenn , Bustinza Oscar F. 
Published: February 2017

Purpose
The unobserved benefits of digital technologies are described as digital dark matter. Product service systems (PSSs) are bundles of products and services that deliver value in use, which is unobserved but generates benefits. This paper aims to empirically quantify digital dark matter within PSSs and correlates that measure with national competitiveness.

Design/methodology/approach
A novel methodology establishes the link between customer needs and a product and digital service portfolio offered across ten developed economies. The case context is the music industry where product and services are often substitutes – a cannibalistic PSS. Consumer information is obtained from a unique database of more than 18,000 consumer surveys. Consumer demand for digital formats is modelled and predicted through logistic regressions.

Findings
The work provides inverse estimations for digital dark matter within PSSs by calculating the gap between supply and demand for digital offers – described as the business model challenge. The USA has the lowest business model challenge; the home of major companies developing digital technologies. Digital dark matter is shown to be positively correlated with national competitiveness and manufacturing competitiveness indices.

Practical implications
The success of a cannibalistic PSS requires good understanding of market demand. Governments embarking on soft innovation policies might incentivise the development of service-orientated business models based on digital technologies.

Originality/value
Work expands theory on the concept of digital dark matter to the PSS literature. Empirically, a novel method is proposed to measure digital dark matter.

WeChat Library: a new mode of mobile library service
Authors: Wei Qunyi , Yang Yang 
Published: February 2017

Purpose
This study aims to introduce a new mode of mobile library service, named “WeChat Library”, developed under the WeChat (social media platform) public service platform. The design and realization of WeChat Library is also presented with Chongqing University Library taken as the example.

Design/methodology/approach
This study designed a new mobile library service system, WeChat Library of Chongqing University Library, analyzed its construction cost and usage statistics and discussed the advantages of the new service mode.

Findings
Investigation results showed that 84.6 per cent of the “985” universities opened up WeChat Libraries, which signified that WeChat Library has become one of the important mobile service modes for Chinese university libraries. WeChat Library received high appreciation from the patrons; in 20 months of operation, 20.3 per cent of patrons in Chongqing University had used WeChat Library. The five most commonly used services are OPAC retrieval, items borrowed, personal center, resource discovery and announcements. WeChat Library was found to have many advantages, such as low development cost, automatic cross-platform service, adaptive screen, low acceptance cost, easier promotion, strong user viscosity, strong interactivity and real-time consulting.

Practical implications
The functional design and technological architecture of WeChat Library was presented with Chongqing University Library taken as the example. The technical realization of several unique services, namely, QR code access, space reservation and overdue reminders, was also demonstrated. The study will provide favorable suggestions and references for other libraries that have also launched the WeChat Library.

Originality/value
The mainstream service mode of mobile libraries is application for mobile terminals (APP). Although mobile services are applied extensively in China, numerous small- and medium-sized libraries are still unable to provide mobile services for patrons primarily because the investment is too high to bear for some libraries. Therefore, mobile library services urgently need a more economical model of mobile services. The most prominent advantages of WeChat Library are its low development cost and low technology threshold. WeChat Library can provide a better solution for mobile library services.
Simplified model for polyurethane foaming in porous media
Authors: Sadrhosseini Hani , Bazkhane Saed 
Published: February 2017

Purpose
The purpose of the study is to present a simplified model to replace the complicated foaming simulations for investigating the liquid polyurethane behavior just before solidification.

Design/methodology/approach
This model is inspired from the traveling heater method of crystallization because of the low injection velocity. Besides, the heat generated during the reaction is considered as a heat source function in the energy equation.

Findings
Various distributions of the heat generation function inside the geometry have been studied to choose the most realistic one. Effect of parameters such as the soil material and porosity on the temperature distribution and flow field are examined for different values of heat flux on the boundaries. Results show an almost linear dependency of pressure drop to the velocity, a uniform velocity profile and an expected temperature distribution compared to literature, which approves the suggested model.

Originality/value
A new model is presented in this study for foaming which replaces a heat generation function (exponential) in the source term of the energy equation instead of the heat produced at the exit boundary (the solid–liquid interface), and the traveling method is used instead of moving the geometry; besides, the growth ratio has been neglected; therefore, this model has been validated by a foaming simulation to confirm the suggested simplified idea.
Flow impingement on a perforated plate at an angle of attack
Authors: Bayazit Yilmaz , Sparrow Eph , Gorman John 
Published: February 2017

Purpose
The purpose of this paper is to provide both directly applicable fluid-flow results and fluid-mechanic fundamentals for flow impinging at an angle of attack on a perforated plate.

Design/methodology/approach
A physical situation was modeled with high fidelity, and the model was implemented by numerical simulation. The simulations spanned all possible flow regimes including laminar, intermittent (transitional) and turbulent, and the Reynolds numbers that defined each flow regime were definitively determined. The Reynolds numbers ranged from 0.1 to 30,000, the angles of attack included 0, 5, 15 and 22.5° and the host duct dimensions varied appropriately.

Findings
It was found that the perforated-plate pressure drop decreased moderately with an increasing angle of attack, an outcome directly relevant to design. The pattern of fluid flow caused by the presence of the plate was dominated by a large recirculation zone situated downstream of the plate in a corner between the plate and an adjacent wall. The recirculation zone played the role of a blockage which deflected the flow emerging from the apertures in the plate toward the opposite wall.

Originality/value
(a) Pressure drop information directly applicable to design, (b) downstream distance from the plate at which the plate-created flow disturbance disappears, (c) account taken of the intermittent flow regime between laminar and turbulent, (d) implementation of a new metric to characterize the strength of turbulence.
The use of educational game design and play in higher education to influence sustainable behaviour
Authors: Mercer Theresa G. , Kythreotis Andrew P. , Robinson Zoe P. , Stolte Terje , George Sharon M. , Haywood Stephanie K. 
Published: February 2017

Purpose
The purpose of this paper is to discuss a novel life cycle approach to education for sustainable development (ESD) where the students become “design thinkers”.

Design/methodology/approach
A case study on the creation, development and utilisation of educational games by university students is presented. The paper discusses the case study in the context of Kolb’s experiential learning and dynamic matching model, Perry’s stages of intellectual development and Beech and Macintosh’s processual learning model. The data used were from questionnaire feedback from the pupils who played the games and students who designed the games. Further qualitative feedback was collected from local schools involved in playing the games created by the students.

Findings
Overall, the students responded positively to the assessment and would like to see more of this type of assessment. They enjoyed the creativity involved and the process of developing the games. For the majority of the skill sets measured, most students found that their skills improved slightly. Many students felt that they had learnt a lot about effectively communicating science. The school children involved in playing the student-created games found them accessible with variable degrees of effectiveness as engaging learning tools dependent on the game.

Originality/value
This paper contributes a new approach to ESD which incorporates learner-centred arrangements within a full life cycle of game creation, delivery, playing and back to creation. The games can be used as a tool for enhancing knowledge and influencing behaviours in school children whilst enhancing ESD capacity in schools. The assessment also helps forge important links between the academic and local communities to enhance sustainable development.

Authors: Landrum Nancy E. , Ohsowski Brian 
Published: February 2017

PurposeThis study aims to identify the content in introductory business sustainability courses in the USA to determine the most frequently assigned reading material and its sustainability orientation.Design/methodology/approachIn total, 81 introductory sustainable business course syllabi reading lists were analyzed from 51 US colleges and universities. The study utilized frequency counts for authors and readings and R analysis of key words to classify readings along the sustainability spectrum.FindingsThe study reveals the most frequently assigned authors and readings in US sustainable business courses (by program type) and places them along the sustainability spectrum from weak to strong. In total, 55 per cent of the top readings assigned in the sample advocate a weak sustainability paradigm, and 29 per cent of the top readings advocate a strong sustainability paradigm.Research limitations/implicationsThis study focused on reading lists of introductory courses in the USA; cases, videos and supplemental materials were excluded, and the study does not analyze non-US courses.Practical implicationsThe findings of this study can inform instructors of the most commonly assigned authors and readings and identify readings that align with weak sustainability and strong sustainability. Instructors are now able to select sustainable business readings consistent with peers and which advance a weak or strong sustainability orientation.Originality/valueThis is the first research to identify the most commonly assigned authors and readings to aid in course planning. This is also the first research to guide instructors in identifying which readings represent weak versus strong sustainability.

Education for sustainability using a campus eco-garden as a learning environment
Authors: Cheang Chi Chiu , So Wing-Mui Winnie , Zhan Ying , Tsoi Kwok Ho 
Published: February 2017

PurposeThis paper aims to explore stakeholder perspectives of the role of a campus eco-garden in education for sustainability (EfS). It will combine the perspectives to highlight a powerful learning environment (PLE) for university students to realize the concept of EfS.Design/methodology/approachSemi-structured interviews were conducted to reveal stakeholder understandings of a campus eco-garden, as well as its associated expectations of learning activities and education outcomes. Three stakeholder groups were interviewed; designers, educators and environmental and non-environmental subject-related students.FindingsAll three stakeholder groups expected cognitive learning of EfS to be enhanced by the eco-garden. The use of affective learning was not strongly expected by the stakeholders. Psychomotor learning was believed to be the most difficult to realize. To fulfill the potential of the eco-garden in EfS, all stakeholders suggested learning activities and roles for both students and teachers. The combined perspectives of the stakeholders helped to visualize a PLE to aid EfS.Practical implicationsThis study underlines the importance of effective communication of expectations between stakeholders. It underlines the importance of integrating educational activities with the eco-garden as a PLE, highlighting the roles of teachers and students. It also sheds light on the importance of introducing a cultural component to the EfS program.Originality/valueThis is the first study to apply the PLE theory to enhance EfS with the aid of infrastructure. Both users and designers reveal their views on the planning of the campus eco-garden, especially in its educational function. The study is possibly the first to reveal the differences in expectations between designers and other stakeholder groups (teachers and students) using Köningset al.’s (2005) combination-of-perspectives model.
Grey prediction with residual modification using functional-link net and its application to energy demand forecasting
Authors: Hu Yi-Chung 
Published: February 2017

Purpose
Energy demand is an important economic index, and demand forecasting has a significant role when devising energy development plans for cities or countries. GM(1,1) model has become popular because it needs only a few data points to construct a time-series model without statistical assumptions. Several methods have been developed to improve prediction accuracy of the original GM(1,1) model by only estimating the sign of each residual. This study aims to address that this is too tight a restriction for the modification range.

Design/methodology/approach
Based on the predicted residual, this study uses the functional-link net (FLN) with genetic-algorithm-based learning to estimate the modification range for its corresponding predicted value obtained from the original GM(1,1) model.

Findings
The forecasting ability of the proposed grey prediction model is verified using real energy demand cases from China. Experimental results show that the proposed prediction model performs well compared to other grey residual modification models with sign estimation.

Originality/value
The proposed FLNGM(1,1) model can improve prediction accuracy of the original GM(1,1) model using residual modification. The distinctive feature of the proposed model is to use an FLN to estimate sign and modification range simultaneously for the predicted value based on its corresponding predicted residual obtained from the residual GM(1,1) model.
Words fly away, writings remain – paradoxes in and around documents
Authors: Michaud Valérie 
Published: February 2017

PurposeThis paper makes a case for the investigation of organizational paradoxes through the analysis of documents. After having presented what paradoxes are and the methodological challenges of studying them, the paper turns to document research, with emphasis on its potential contribution to paradox research. More specifically, document research typically provides ready-to-code data in a nonintrusive manner, allowing for the potential longitudinal, multilevel and multivoice analysis of organizational paradoxes and their management, in practice. To illustrate this, the purpose of this paper is to explore exemplar research based on multiple approaches to the study of different paradoxes in/around various documents and sets a research agenda.Design/methodology/approachExemplar research on paradoxes using organizational documents as central data are presented. This highlights the range of documents and analytical strategies that can be used to explore organizations’ discursive management of paradoxes, as well as the roles documents can play in organizational contexts marked by different types of paradoxes.FindingsA research agenda is developed, formulated around the needs to study paradoxes within documents and around them; grasp the discursive strategies deployed in documents to deal with paradoxes and/or the action of documents in contexts marked by paradoxes; follow the organizational processes involving documents, paying special attention to the paradoxes surrounding the development, adoption and appropriation of documents; and compare paradoxes in documents and those around the documents’ mobilization.Originality/valueDespite growing interest in organizational paradoxes, reflections on methodological approaches to exploring them remain scarce and alternative methods largely unexplored. This paper makes the following proposition: organizational documents (strategic plans, annual reports, policies, websites, etc.) can provide a valuable entry point to explore organizational paradoxes.
