Abstract
A principal problem of information systems (IS) development today is how to integrate the work activity and social context of users into the IS which is being designed. This paper aims to delineate a sociocybernetic approach which enlightens the relationship between IS design activity, use activity, and the embedded social context. First and second order cybernetics are employed as a general skeleton or structure for conducting the sociocybernetic approach. Approaches from social autopoiesis theory and activity theory are introduced respectively to provide the skeleton of cybernetics with flesh and blood elements of real problems. An emerging conceptual body resulting from an organic integration of the cybernetic structure and social‐psychological elements which demonstrates the relationship between IS design activity, use activity, and embedded social context is presented.

Abstract
Purpose
The purpose of this study is to explore the relationship between big data and supply chain platform in China’s retail industry. With the emergence of big data resources and technologies, the business pattern of new retail advocates the combination of online and offline channels. Supply chain platform plays a key role in the implementation of retail activities, which has gradually become a research hotspot in the cross field of operations management and information system.
Design/methodology/approach
Through the method of literature review and case study, this study empirically explores how big data shapes supply chain platform to support new forms of online retail by grounded theory.
Findings
The model framework is validated by reliability test and coding method to process survey materials. The results identify the overall antecedents of supply chain platform and reveal positive effects between big data and new retail. The findings help firm managers build a big data-driven supply chain to support new retail.
Originality/value
There are insufficient studies on theoretical frameworks and interaction relationships among big data, supply chain platform and new retail.

The purpose of this paper is to investigate the optoelectronic properties of the multichannel ZnO UV photodetectors.
Abstract
Purpose
The purpose of this paper is to investigate the optoelectronic properties of the multichannel ZnO UV photodetectors.
Design/methodology/approach
ZnO nanowires were assembled by dielectrophoresis for the UV photodetectors. Different ZnO channels were adjusted by different alternating current voltages and investigated for UV optoelectronic properties.
Findings
The number of the ZnO channels increases with the enhancing alternating current voltage. Optimum performance of the UV photodetectors is obtained with more channels.
Originality/value
Dielectrophoresis is a promising method for controllable assembly of multichannel ZnO photodetectors. ZnO photodetectors with more channels demonstrate a good response to 380-nm UV light, which shows great potential application in UV photodetector.

Abstract
Purpose
The suppliers of experimental resources required in megaprojects are driven by short-term interests, presuming that participation in the digital platform would only increase their inputs and fail to rapidly expand their revenue, resulting in their insufficient motivation to participate. This paper aims to design effective incentives for these suppliers exhibiting the aforementioned behaviour to drive them to participate and actively share their resources on the platform.
Design/methodology/approach
This paper develops incentives for applying the digital platform for experimental resource sharing by using a reverse induction approach to model and solve an incomplete information game. It compares the traditional experiment management mode and the new mode of applying the digital platform, taking the degree of sharing experimental resources on the platform as the variable and constructing three incentive models. By analysing these different degrees of sharing and the different experimental and informatisation capabilities of the suppliers, it could obtain the optimal incentive scheme for changes in sharing behaviour.
Findings
The results show that the designed incentives could increase the participation of suppliers in the platform and the number of their shared resources and make the benefits of both the supplier and the demand side reach the optimal state of a win-win situation. However, a higher degree of sharing by suppliers does not yield better results. In addition, the incentive coefficients for this degree should be set based on the suppliers’ different experimental and informatisation capabilities and the ratio of input cost-sharing, so as to avoid blind inputs from both supply and demand.
Originality/value
This study fills the research gap regarding incentives of the digital platform of experimental resource-sharing for megaprojects; it contributes to the body of knowledge by providing a quantitative perspective of understanding the experimental resource-sharing behaviour that motivates the usage of the digital platform. Furthermore, it reveals the incentive mechanism for application in different scenarios, and quantitative analysis is conducted to provide practical insights into promoting the new experiment management mode in megaprojects for more effective incentivisation.

Abstract
Purpose
This study aims to clarify the mechanism of film hole location at the span-wise direction of an internal cooling channel with crescent ribs on the adiabatic film cooling performance, three configurations are designed to observe the effects of the distance between the center of the ellipse and the side wall(Case 1, l = w/2, Case 2, l = w/3 and for Case 3, l = w/4).
Design/methodology/approach
Numerical simulations are conducted under two blowing ratios (i.e. 0.5 and 1) and a fixed cross-flow Reynolds number (Rec = 100,000) with a verified turbulence model.
Findings
It is shown that at low blowing ratio, reducing the distance increases the film cooling effectiveness but keeps the trend of the effectiveness unchanged, while at high blowing ratio, the characteristic is a little bit different in the range of 0 = x/D =10.
Research limitations/implications
These features could be explained by the fact that shrinking the distance between the hole and side wall induces a much smaller reserved region and vortex downstream the ribs and a lower resistance for cooling air entering the film hole. Furthermore, the spiral flow inside the hole is impaired.
Originality/value
As a result, the kidney-shaped vortices originating from the jet flow are weakened, and the target surface can be well covered, resulting in an enhancement of the adiabatic film cooling performance.

Abstract
Purpose
This paper gives a comparative analysis of the foundation of sinology in two Canadian universities. Despite not having diplomatic exchanges, Canada's new relationship with the People's Republic of China (PRC) ignited a China interest in the Canadian academe. Through York University and the University of Guelph (U of G)'s experiences, readers will learn the rewards and challenges that sinology brings to Canadian higher education.
Design/methodology/approach
This paper offers an overview of the historical foundation of sinology in the Canadian academe. Who pushes through this process? What geopolitical developments triggered young and educated Canadians to learn about China? This paper assesses York and Guelph's process in introducing sinology by relying on university archival resources and personal interviews. Why was York University successful in its mission, which, in turn, made into a comprehensive East Asian Studies degree option in 1971? What obstacles did the U of G face that prohibited it from implementing China Studies successfully?
Findings
After 1949, Canada took a friendlier relationship with the PRC than its neighbor in the south. As China–Canada relations unfolded, Canadian witnessed a dramatic state investment in higher education. The 1960s was a decade of unprecedented university expansion. In the process, sinology enjoyed its significant growth, and both York University and the U of G made their full use of this right timing. However, China Studies at the U of G did not take off. Besides its geolocation disadvantage, Guelph's top-down managerial style in the 1960s, which resulted in collegial disillusionment, was also a significant barrier to this program's success.
Originality/value
Before the Internet age, universities were the first venues for most Canadians to acquire their initial academic knowledge of China. After the Second World War, sinology became popular among students as China became one of the world's “Big Fives”. More Canadians became romanticized with Maoism while opposing America's containment policy. York and Guelph exemplified this trend in Canadian history. Contrary to popular belief, historian Jerome Chen did not establish York's China Studies. Likewise, an ex-US diplomat John Melby did not bring China into Guelph, sinology arrived due to individual scholastic initiatives. Visionaries saw envisioned China's importance in the future world community.
