Authors: Fan Ken Yiu Kwan , Lo Patrick , Ho Kevin K.W. , So Stuart , Chiu Dickson K.W. , Ko Eddie H.T. 
Published: April 2020

Purpose
This paper aims to study the information needs and online information-seeking behaviors on mobile platforms of performing arts students at a college level.

Design/methodology/approach
Survey instruments were used to collect data from performing arts students at the Hong Kong Academy of Performing Arts (HKAPA), a metropolitan’s major performing arts tertiary institution. Data collected were analyzed through descriptive statistics and other statistical methods, and the music-related students were compared with the production-related students.

Findings
The result reveals that performing arts students all owned their mobile devices and often used mobile apps for non-academic purposes, but they did not often use mobile library services or read online academic contents with their mobile devices. The participants considered inadequate signal coverage, slow loading time, difficulty in reading on a mobile device and the lack of specialized mobile apps as more significant barriers affecting their usage. There are some significant differences between the music-related and production-related student groups in that music-related students watched lectures on the library websites and used electronic music scores more often than the production-related students.

Practical implications
This study contributes to the input for enhancements and policies to future mobile services and facilities of performing art libraries.

Originality/value
There have been scant studies on the mobile learning needs of performing arts students, especially in Asia.

Authors: Ganesan Surendar , Esakki Balasubramanian 
Published: April 2020

PurposeThe aim of this article is to minimize the drag of an unmanned amphibious aerial vehicle (UAAV) and enhancing the endurance.Design/methodology/approachVarious surface geometrical profiles such as rectangular, semicircular groove, razor blade and V-groove riblets are incorporated into the UAAV, and computational fluid dynamic (CFD) analysis is performed for various angles of attack at diverse vehicle speed conditions to estimate the coefficient of drag considering k–e turbulence model. Comparative evaluation between riblet and blunt body shape methodology is performed. Wind tunnel experiments are conducted to validate the flow characteristics around the UAAV.FindingsIt is observed that V-groove riblet method produced minimal drag in comparison with other profiles. The pressure distributions around UAAV for various geometrical profiles suggested that V-groove profile has achieved minimal vortex region, flow separation and turbulent boundary layer near to the outer profile.Originality/valueThe CFD analysis of UAAV for various riblet configurations and validation with wind tunnel smoke test confirms that UAAV with V-groove riblet provides low drag.

Authors: Rodrigues Gabriel Welfany , Bittencourt Marco Lucio 
Published: April 2020

Purpose
This paper aims to numerically investigate the surface texturing effects on the main bearings of a three-cylinder ethanol engine in terms of the power loss and friction coefficient for dynamic load conditions.

Design/methodology/approach
The mathematical formulation considers the Partir-Cheng modified Reynolds equation. The mass-conserving Elrod-Adams p-θ model with the JFO approach is used to deal with cavitation. A fluid-structure coupling procedure is considered for the elastohydrodynamic lubrication. Accordingly, a 3-D linear-elastic substructured finite element model obtained from Abaqus is applied

Findings
Simulations were carried out considering different dimple texture designs in terms of location, depth and radius. The results suggested that there are regions where texturing is more effective. In addition, distinct journal rotation speeds are studied and the surface texture was able to reduce friction and the power loss by 7%.

Practical implications
The surface texturing can be a useful technique to reduce the power loss on the crankshaft bearing increasing the overall engine efficiency.

Originality/value
The surface texturing performance in a three-cylinder engine using ethanol as fuel was investigated through numerical experimentation. The results are supported by previous findings.

Enablers of and constraints on employees' information sharing on enterprise social media
Authors: Laitinen Kaisa , Sivunen Anu 
Published: April 2020

PurposeThe purpose of this study is to investigate the various enablers of and constraints on employees' information sharing on an enterprise social media platform. It draws on two theoretical perspectives, communication privacy management theory and the technology affordance framework, as well as on empirical data in an attempt to paint a comprehensive picture of the factors shaping employees' decisions to share or not share information on enterprise social media.Design/methodology/approachThis qualitative field study is based on semi-structured interviews and enterprise social media review data from a large Nordic media organization.FindingsOn an enterprise social media platform, privacy management principles shape employees' information-sharing decisions in relation to personal privacy boundaries, professional boundaries and assumed risks, online safety concerns and perceived audience. Additionally, the technological affordances of visibility, awareness, persistence and searchability shape employees' information sharing in varying and sometimes even contradictory ways. Finally, organizational factors, such as norms, tasks and media repertoires, are associated with employees' information-sharing decisions. Together, these three dimensions, personal, technological and organizational, form a model of the enablers of and constraints on employees' decisions to share information on enterprise social media.Originality/valueThis study extends the understanding of different factors shaping employees' decisions to share or not share information on enterprise social media. It extends the two applied theories by uniquely combining interpersonal privacy management principles with a technological affordance framework that focuses on the relationship between the user and the technology. This research also furthers the authors' knowledge of what privacy management principles mean in the organizational context. This study shows connections between the two theories and extends the understanding of technology affordances as not only action possibilities but also constraining factors. Additionally, by revealing what kinds of factors encourage and inhibit information sharing on enterprise social media, the results of this study support organizations in their efforts to manage information sharing on enterprise social media systems.
Drivers of ICT investments in bakery and sugar confectionery processed food sub-sector in India
Authors: GR Navyashree , Bhat Savita 
Published: April 2020

PurposeInformation and communication technology (ICT) is a general-purpose technology, which plays an important role in improving the efficiency of a business firm. Nowadays, investment on ICT has become necessary for every business firm in different sectors of the economy. However, firms need to be very cautious while investing on a particular ICT, which is suitable for their businesses. Thus, it becomes necessary for the firm to understand its internal organizational characteristics to invest better on ICT. Therefore, the objective of the present study is to understand the organizational factors, which influence investment on ICT at the firm level.Design/methodology/approachThe technology–organization–environment (TOE) framework is adopted to understand the organizational factors which influence a firm's ICT investment. The sample for the study is the firms belonging to bakery and sugar confectionery sector, which is one of the important sub-sectors of processed food industry in India. The data for analysis is extracted from a secondary source, namely the Prowess Database. The study uses two-step system GMM, a method of generalized method of moment (GMM), to identify the organizational determinants of ICT investment at the firm level.FindingsThe study finds that previous-year investment on ICT has a significant impact on firms' present-year investment on ICT. The result of the econometric method also shows that firms which are larger, labour-intensive and highly liquidated are the ones investing more on ICT in the present study.Research limitations/implicationsAs mentioned, the study examines the ICT investment determinants of firms belonging to one of the important sub-sectors of processed food industry of the Indian economy. However, the result of the study is not to be generalized since it is related only to a specific industry. Further, the data used in the study is limited by secondary sources and therefore, requires data from primary sources for in-depth investigation of ICT investment determinants at the firm level.Originality/valueThis paper bridges a research gap by examining the determinants of ICT investment of one of the important industry sectors in particular to developing countries. The paper contributes to the growing research on information technology adoption by using factors within the TOE framework to explain a processed food firm's investment on ICT.

Authors: Calegari Luiz Philipi , Avalone Marianne Costa , Fettermann Diego Castro 
Published: April 2020

PurposeThis study is to propose a procedure to support decisions on which enablers should be employed to minimize the impact of barriers to implementing mass customization strategies in food companies.Design/methodology/approachThrough interpretive structural modeling, the authors analyzed the relationships between barriers. Then, with an approach similar to the quality function deployment technique, commonly used in general product and process development, the authors clarified the relationships between barriers and enablers.FindingsThe results revealed 19 barriers and 17 enablers for implementing food mass customization. The analysis indicates that most of the barriers (16) present strong associations with each other. The barrier “products with non-customizable features” depends on the whole chain of associations and causes a minor impact on the other barriers. In turn, the barrier “ingredient incompatibility” causes impact over the whole chain, and its dependence on other barriers is very low.Research limitations/implicationsThe results were tested in a single Brazilian company in the food sector.Practical implicationsThe findings can allow food manufacturing companies to focus their efforts on the improvement of enabling technologies, such as smart packaging, Internet of Things and additive manufacture.Social implicationsThis study would help food companies to improve their business and provide better products to society.Originality/valueThere are few recommendations in the literature to how to implement mass customization strategy in companies from the food sector. This study fills in this gap presenting a procedure to guide managerial staff to develop this promising approach for food companies.
Interlinked diversification strategies: evidence from the US farm business households
Authors: Khanal Aditya R. 
Published: April 2020

PurposeThe agricultural sector in the USA has experienced significant structural changes. For accommodating farm business, households have diversified their operations adopting various strategies—agricultural, structural, environmental, and income strategies. The purpose of this study is to analyze the factors influencing farmer’s diversification strategies while taking into account the simultaneous decision-making process.Design/methodology/approachThis study uses a nation-wide farm household data from the US. The diversification decisions are analyzed using multivariate probit regressions.FindingsThe study suggests that agricultural, structural, environmental, and income diversification strategies are interlinked. Specifically, results indicate that, on one hand, environmental and income diversification strategies are positively interlinked. On the other hand, agricultural and structural diversification strategies are positively interlinked. Additionally, the factors representing location, farm, and farmer characteristics, farm type, and financial condition of the farm are major determinants in the choice of farm diversification strategies.Research limitations/implicationsIn this paper, diversification activities are broadly classified under four strategies: agricultural, structural, environmental, and income. Depending on the context and country, the definition and strategy set may need revision.Practical implicationsStrong complementary between diversification strategies suggests that studies analyzing farm household decisions and strategies need to account for the simultaneous decision-making process. As decisions are interlinked, separately analyzing one specific strategy may lead to biased estimates. Farm business households need to develop multiple skills and flexible capacities to tackle farming-related issues, including structural changes, risk management, and income enhancing activities. Improving employment opportunities for the rural farming population can stimulate structural diversification.Originality/ValueThis paper contributes to limited literature about diversification by analyzing factors influencing different diversification decisions and finds interlinkage between decisions.
Model-based teaching of physics in higher education: a review of educational strategies and cognitive improvements
Authors: Cascarosa Esther , Sánchez-Azqueta Carlos , Gimeno Cecilia , Aldea Concepción 
Published: April 2020

PurposeUntil relatively recently, science teaching was based on conveying theoretical concepts. Nevertheless, in the last few years we have gradually understood the importance of building mental models that represent scientific reality. Model-based science teaching has been used at a school level with satisfactory results. However, only a few studies have been published so far on science modelling in higher education.Design/methodology/approachThe present thematic review analyses the concept of model in science and the works published in recent years on models in physics education.FindingsThroughout these years, special importance has been given to the acquisition of student learning models. These models can either be introduced in the teaching process or acquired by students in their learning process using specific teaching tools. As a conclusion of this review, the authors say that although such strategies are increasingly used in the teaching of science at a school level, few works delve into the importance of acquiring models in higher education. More specifically, there are few research works published in the context of teaching physics in university courses.Originality/valueThis study review and analyses works published on this issue and aims to provide knowledge as a starting point for future research.
Grasha–Riechmann student learning style scales: an Argentinian version
Authors: Freiberg Hoffmann Agustín , Fernández Liporace Mercedes 
Published: April 2020

PurposeThe study analyses psychometric features of the Grasha–Riechmann student learning style scale. It measures the instructional preferences of students attending different educational stages.Design/methodology/approachThe scale was translated from English to Spanish. Content and face validity evidences were analysed. After that, construct validity evidences – exploratory factor analysis, confirmatory factor analysis, factorial invariance analysis – and internal consistency were examined. Data were collected from samples composed of high school and college students from Argentina.FindingsThe adapted version, a four-factor 12-item scale, suitable to be used in local students, measures four learning styles – competitive, independent, dependent and collaborative. The model showed a better fit when compared to rival models – three-factor and six-factor. Besides, the four-factor model verified its factorial invariance in high school and college students' groups composing the sample. The internal consistency indices were adequate for every dimension (ordinal α > 0.70).Research limitations/implicationsDespite satisfactory results of the internal validity evidences and the internal consistency analysis, further studies should analyse external validity evidences – criterion and predictive evidences.Practical implicationsThe adapted version of the scale is suitable to be used by teachers in order to examine learning preferences in their students. Such information will allow the adaptation of teaching methods regarding the actual students' needs.Originality/valueThe Grasha–Riechmann student learning style scale’s Argentinian adaptation is presented. It is a valid and reliable measure of learning styles suitable to be used in high school and college.
Do sustainability practices buffer the impact of self-efficacy on organisational citizenship behaviour?
Authors: Pradhan Rabindra Kumar , Jena Lalatendu Kesari , Panigrahy Nrusingh Prasad 
Published: April 2020

PurposeSustainability is seeking for a new approach to bolster organisational success as it is expected to be mobilised through collaborative efforts of employees and management. The present study aims to examine the moderating role of sustainability practices between self-efficacy and organisational citizenship behaviour (OCB).Design/methodology/approachA total of 527 full-time executives employed in Indian public and private manufacturing industries were surveyed. Harman’s single-factor test was carried out using analysis of moment structures (AMOS 20.0) to test the bias associated because of common method variance (CMV). Moderated regression analysis was used through hierarchical models to test the proposed hypotheses.FindingsThe results indicate a positive relationship between self-efficacy and OCB. The significant moderation effect was observed in the interaction graph, as the simple slope analysis indicated relatively high level of sustainability practices and self-efficacy and they were found to be positively associated with OCB.Research limitations/implicationsThe cross-sectional sample of executives employed in Indian manufacturing organisations limits the generalisation of the findings. The study has not figured the temporal effects and hence longitudinal studies have also been proposed for the assessment of causality.Practical implicationsOrganisations are expected to foster inclusiveness and open channel of communication with their employees to execute best sustainable practices. HR department need to create awareness among their employees and establish an ongoing feedback mechanism to promote such psychological drives.Originality/valueThe proposed model and the subsequent findings of the study extend the literature on the relationship among self-efficacy, OCB and sustainability practices. The outcome of this work can be used by HR functionaries and senior management practitioners while formulating and implementing the sustainability strategies.
Making it personal – population health management and the NHS
Authors: McShane Martin , Kirkham Karen 
Published: April 2020

PurposeChanges in demographics and disease patterns are challenging health and care systems across the world. In England, national policies have reset the direction of travel for the NHS. Collaboration, integration and personalisation are intended to become prime principles and drivers for new models of care. Central to this is the concept of population health management. This has emerged, internationally, as a method to improve population health. Fundamental for population health management to succeed is the use of integrated data, analytics combined with professional insight and the adoption of a learning health system culture. This agenda reaches beyond the NHS in England and the public health profession to embrace a broad range of stakeholders. By drawing on international experience and early experience of implementation in the United Kingdom, the potential for health and care systems in England to become world leading in population health management is explored.Design/methodology/approachA viewpoint paper.FindingsPopulation health management is a major change in the way health and care systems look at the challenges they are facing. It makes what is happening to individuals, across the continuum of care, the essence for insight and action. The NHS has the components for success and the potential to become world leading in delivery of population health management as part of its integrated care agenda.Originality/valueThis is the first viewpoint paper to set out how population health management contributes to the integrated care agenda in the NHS.
From technological to social innovation – the changing role of principal investigators within entrepreneurial ecosystems
Authors: Carl Johannes 
Published: April 2020

PurposeBy taking a micro-level perspective, this paper aims to examine the influence of the ongoing paradigm shift from technological to social innovation on principal investigators (PIs) and thereby links the two emerging research fields of entrepreneurial ecosystems and social innovation. The purpose of this paper is to build the basis for future empirical analyses.Design/methodology/approachThe paper is a conceptual paper and therefore focuses on theoretical considerations. Taking a quadruple helix approach, PIs are outlined as central actors of entrepreneurial ecosystems and transformative agents of the innovation process.FindingsPIs can proactively shape the innovation process and thus the shift from technological to social innovation, through various channels. They can affect all other actors of the quadruple helix, e.g. by exerting influence on the process of scientific change, on the public opinion and/or on the industry partners. Further, the paradigm shift might change the universities' role in the quadruple helix, substantiating their importance in the process of social change.Practical implicationsAs PIs are influencing all other actors of the quadruple helix, they are central actors of entrepreneurial ecosystems and thus crucial players in the innovation process. Hence, they need to be supported in fulfilling their role of transformative agents, accelerating and shaping the paradigm shift from technological to social innovation. Universities should therefore reconsider their missions and vision as well as their role within the society.Originality/valueThis paper considers the influence of an ongoing paradigm shift from technological to social innovation on entrepreneurial ecosystems. This work focuses especially on the PIs' role as transformative agents. Therefore, it builds a bridge from entrepreneurial ecosystems to social innovation and thus contributes to both research fields. Moreover, the paper shows the great potential of PIs to influence and shape social innovation.
