Abstract
Purpose
Based on self-determination theory (SDT), this study aims to investigate the motivational antecedents of faculty members’ continuance intention of using online teaching platforms. For this purpose, we introduced a model incorporating basic psychological needs satisfaction (BPNS) and different motivational mechanisms.
Design/methodology/approach
Using a survey study of 312 faculty members, we examined the model by structural equation modeling (SEM).
Findings
The SEM results revealed a positive correlation between BPNS and continuance intention. Additionally, we illustrate the importance of different types of extrinsic motivation. By presenting an alternative model, we demonstrate that the initial-use-identified regulation (one type of extrinsic motivation) has an association with continuance intention (CI). However, this association loses significance if BPNS is present within the model. Moreover, we determined that there is no significant relationship between initial-use external regulation (another type of extrinsic motivation) and faculty members' CI for online teaching. Lastly, the results revealed that pre-use amotivation and intrinsic motivation impact CI through initial-use BPNS.
Research limitations/implications
The results suggest that decision-makers at educational institutions should consider that extrinsic motivation has different types with different impacts and that BPNS has a vital role in faculty members’ intention to continue using online teaching platforms.
Originality/value
This study is novel because it reveals some details of extrinsic motivation effects by offering a model that combines BPNS and different types of motivation in two stages. It is important and rare that we concentrate on the almost neglected issue of faculty members’ motivational perspectives in online teaching, while the literature mainly focuses on students’ perspectives.

Abstract
This chapter offers a critical evaluation of the concept and application of global carceral archipelagos designed as punitive barriers to refugees. With a focus on policies and practices in Australia for over two decades, the chapter shows how more recently, the European Union (EU) and the United Kingdom (UK) are also adopting similar strategies to Australia in a pattern of Western countries turning their backs on their human rights obligations. The histories of colonial practices of the racialisation of certain minorities within and outside nation-state borders are an important aspect of understanding contemporary bordering regimes that exclude refugees. The chapter discusses examples of resistance, as well as alternative politics emerging from refugees who have suffered from the carceral border complex, drawing on creative and collaborative work and practices.

Abstract
Purpose
With respect to two new subjects, i.e. nanofluids and microchannels, in heat transfer systems and modern techniques used for building them, this paper aims to study on effect of using aluminum oxide nanoparticles in non-Newtonian fluid of aqueous solution of carboxy-methyl cellulose in microtube and through application of different slip coefficients to achieve various qualities on surface of microtube.
Design/methodology/approach
Simultaneously, the effect of presence of nanoparticles and phenomenon of slip and temperature jump has been explored in non-Newtonian nanofluid in this essay. The assumption of homogeneity of nanofluid and fixed temperature of wall in microtube has been used in modeling processes.
Findings
The results have been presented as diagrams of velocity, temperature and Nusselt Number and the investigations have indicated that addition of nanoparticles to the base fluid and increase in microtube slip coefficient might improve rate of heat transfer in microtube.
Originality/value
The flow of non-Newtonian nanofluid of aqueous solution of carboxy methyl cellulose-aluminum oxide has been determined in a microtube for the first time.

Abstract
Purpose
In this paper, the forced convection heat transfer of the nanofluid composed of water and AL2O3 nanoparticles is simulated in a two-dimensional horizontal microchannel by injecting the lower wall. The upper wall of the microchannel is 303 K at temperature TH. On the lower wall of the microchannel, there are three holes for flow injection. Other parts of the wall are insulated. In this paper, the effect of parameters such as Reynolds number, slip coefficient and volume fraction of nanoparticles is investigated.
Design/methodology/approach
The boundary condition of the slip velocity is considered on the upper and lower walls of the microchannel. In this work, the flow of nanofluid in the microchannel is considered to be slow, permanent and Newtonian. In the present study, the effect of injection through the microchannel wall on the slip velocity is examined for the first time.
Findings
The results are also presented as velocity profiles and Nusselt number diagrams. It was found that the Nusselt number increases with increasing the amount of slip coefficient of velocity and the weight percentage of solid nanoparticles. The rate of this increase is higher in the high values of the Reynolds number.
Originality/value
A novel paper concerned the simulation of cross-flow injection effects on the slip velocity and temperature domain of a nanofluid flow inside a microchannel.

The purpose of this paper is to improve the lattice Boltzmann method’s ability to simulate a microflow under constant heat flux.
Abstract
Purpose
The purpose of this paper is to improve the lattice Boltzmann method’s ability to simulate a microflow under constant heat flux.
Design/methodology/approach
Develop the thermal lattice Boltzmann method based on double population of hydrodynamic and thermal distribution functions.
Findings
The buoyancy forces, caused by gravity, can change the hydrodynamic properties of the flow. As a result, the gravity term was included in the Boltzmann equation as an external force, and the equations were rewritten under new conditions.
Originality/value
To the best of the authors’ knowledge, the current study is the first attempt to investigate mixed-convection heat transfer in an inclined microchannel in a slip flow regime.

The purpose of this paper is to determine the attractiveness or unattractiveness of cyberloafing in the workplace using Q methodology and the Kano model.
Abstract
Purpose
The purpose of this paper is to determine the attractiveness or unattractiveness of cyberloafing in the workplace using Q methodology and the Kano model.
Design/methodology/approach
The perception of employees towards cyberloafing was investigated based on Q methodology, and then they were prioritized using Kano model. Ten IT companies were selected for the case study. In this study, a mixed method was used. First, 30 participants were interviewed. Next, after extracting the comments, Q-matrix was presented to 30 participants and they completed the matrix cells. Finally, Kano questionnaire was designed using the items obtained from Q methodology and distributed among 30 participants.
Findings
Q methodology led to nine perceptions, and the priorities of Kano model were proponents of increasing employees' dependence on the internet, economic thinkers, the indifferent, dissatisfied, proponents of receiving information, self-control proponents, the profit-minded, mind destroyer and satisfaction-oriented. Cyberloafing is considered unattractiveness with adverse effects. The combination of Q methodology and Kano model can improve the analysis of the results.
Originality/value
This study is one of the few studies in which Q methodology is improved by Kano model. In the past, Q methodology alone examined people’s perception, but by combining these two methods, it is determined which perception is more satisfying and which one is more important, and then a general result can be reached.

Abstract
Purpose
This study aims to revise the weights in the interrelationship matrix of the house of quality.
Desqign/methodology/approach
After determining customer requirements (CRs) and product design characteristics (PDCs), a house of quality (HoQ) has been developed and the interrelationships between CRs and PDCs have been determined and classified using the Kano model. The PDCs have been prioritized based on the classic HoQ and the revised HoQ. Finally the results have been compared and discussed. The television design of Entekhab Industrial Group, the largest producer of home appliance products in Iran has been selected as a case study.
Findings
Results indicated different sets of priorities derived from the two approaches. Particularly, the difference between the revised HoQ and the classic approach was due to the nonlinear relationship between CRs and PDCs.
Research limitations/implications
This study was performed merely on a single product of a company, and the case study results cannot be generalized to all of the home appliance industries.
Originality/value
Developing the application of the Kano model in computing and revising the weights of the cells in the interrelationship matrix of HoQ is the main contribution of this paper.
