Abstract

Purpose

Green technology adoption (GTA) in small and micro enterprises (SMEs) is a complex multi-attribute group decision-making issue. Conflicts of opinions can hamper the achievement of group coherence. The purpose of this paper is to solve the conflict decision-making problem in SMEs.

Design/methodology/approach

This paper reconstructs the GTA evaluation index system for SMEs and proposes an intragroup coordination relationship model to mitigate group decision-making conflicts based on the cloud model and social networks (GCS). The numerical characteristics of these GTA indicators are determined using fuzzy theory and cloud model.

Findings

It was found that establishing a trust relationship network and a conflict coordination relationship could improve the consistency of group decision-making. The degree of coordination has subtle differences with the trust relationship. Particularly, the coordination relationship has obvious influences on the decision-making results among small groups in SMEs.

Originality/value

The conflict coordination model can significantly improve the consistency of group decision-making in SMEs. At the same time, it discusses the differences between the level of conflict coordination and the trust propagation in the process of group decision-making.

Abstract

Purpose

The purpose of this paper is to establish a deterministic equivalent income model (DEIM) based on the risk cost (RC) and risk aversion of investors. The model fully considers both subjective and objective factors that affect risk investment and reasonably evaluates risk investment schemes to choose the correct investment scheme and gain greater investment returns.

Design/methodology/approach

The utility function is used to measure the extent to which an investor is satisfied by investment returns in various scenarios. Risk aversion expresses subjective attitude of investors to risk. RC represents risk loss in currency. This methodology is based on risk aversion function, utility function and RC theory to establish DEIM.

Findings

This study shows that investors with different risk preferences have different certainty equivalent returns (CER), so their choices of investment options change accordingly.

Practical implications

In this paper, the authors use DEIM to test an investment case and conclude that the CER and investment scheme both change with different risk preferences. At the same time, case analysis shows that DEIM is reasonable and stable when evaluating risk investment schemes.

Originality/value

In this study, the authors innovate by introducing both the RC and risk aversion degree into risk investment schemes evaluation and by deriving a utility function from the absolute risk aversion function to build a utility decision matrix and establish DEIM. The model combines the subjective and objective factors that influence risk investment decisions.

The purpose of this paper is to solve the tracking problem for free-floating space manipulators (FFSMs) in task space with parameter uncertainties and external disturbance.

Abstract

Purpose

The purpose of this paper is to solve the tracking problem for free-floating space manipulators (FFSMs) in task space with parameter uncertainties and external disturbance.

Design/methodology/approach

In this paper, the novel cerebellar model articulation controller (CMAC) is designed with the feedback controller. More precisely, the parameter uncertainties in the FFSM are considered for achieving the robustness.

Findings

By using the dynamically equivalent model, the CMAC can be designed and trained with the desired performance, such that the prescribed trajectory can be followed accordingly. The simulation results are presented for illustrating the validity of the derived results.

Originality/value

Based on the designed CMAC, the tracking error would be approaching zero by choosing appropriate quantization level in CMAC and the corresponding learning rules can be tuned online.

The authors with maximum number of citations are Yan, Zaho, Bengio, Weizenbaum, Song, Zhou and Maedche with jointly 180 citations. Research is been contributed by different countries where the United States is the country with highest number of documents published. The United States contributes 17% of the total production in the area of chatbots and virtual assistants. The analysis shows that the area is gaining momentum as contribution in this area is been increasing in last few years.

Research limitations/implications

The study shows that several branches of chatbots are also in mainstream like natural language processing, e-learning, behavioural research, conversational agents, virtual assistants, human–computer interaction, natural language and so on. It provides a wider scope to authors and researchers to gain useful insights. The bibliometric study will provide a broader spectrum in this area.

Social implications

The developments in technology and also the effect of COVID-19 pandemic is boosting the adoption of technology in different sectors. Deployment of technology will uplift the economy and social infrastructure. Society can avail different services from their comfort area and also in real time. This will help in reducing wastage of resources like people visiting offices for routine jobs which can be easily availed from their workplace. Society may access better services without much human interaction.

Originality/value

This paper adds significant contribution to the existing literature by analysing the published papers from Scopus database. The study contains new and significant information as this study covers all industries where chatbots and virtual assistants are being applied whereas in previous literature only specific industry has been taken into consideration.

Abstract

Purpose

This paper aims to assess the marginal value of several types of open space in a single family residential market. It also aims to test the hypothesis that locating closer to open spaces might be a substitute for the size of a homeowner's own yard.

Design/methodology/approach

Using data from Wake County, North Carolina in the US hedonic modeling is used to estimate the house price as a function of the quantities of a property's characteristics, including the property's access to different types of open spaces, property structural features, public services, disamenity features, neighborhood socio‐economic characteristics, and accessibility measures.

Findings

The findings were that housing prices increase with a property's proximity to certain types of open land uses, and that the size of those nearby open spaces also impacts home price. More importantly, the findings concluded that the value of being adjacent to public open spaces, having more public open spaces within walking distance of the property, and being closer to the nearest open space is greater for properties with smaller private yards.

Originality/value

This paper explicitly tests the relationship between yard size and the proximity value of various types of open spaces. The paper also discusses the implications of the research findings for land use planning and smart growth development.

This paper aims to explore the preparation and tribological performance of MoS2 nanoparticles supported on fly ash (FA) microparticles.

Abstract

Purpose

This paper aims to explore the preparation and tribological performance of MoS2 nanoparticles supported on fly ash (FA) microparticles.

Design/methodology/approach

FA was activated by NaOH, oleic acid and HCl to obtain three modified FA samples. Nano-MoS2 was deposited on them to form MoS2/FA additives for poly-α-olefin (PAO) modification. Tribological tests were conducted on a reciprocating rig through the ball-on-disk friction manner. Using X-ray diffraction, scanning electron microscope, energy dispersive spectrometer, Raman spectrometer and element analyzers, the products and their lubrication mechanisms were characterized.

Findings

At 1.5 Wt.%, nano-MoS2 and MoS2/FA could remarkably improve the tribological properties of PAO. The nano-MoS2 deposited on the HCl-activated FA presented better lubrication performance than nano-MoS2. It could reduce friction and wear by approximately 27% and approximately 66%, respectively. The lubrication of MoS2/FA can be attributed to the formation of MoS2 and carbon containing lubricating film.

Originality/value

FA was applied as a supporter to prepare MoS2/FA lubricants. The reuse of FA, a solid waste, is important for environmental protection. Moreover, MoS2/FA is more economical than nano-MoS2 as a lubricant, because it contains approximately 71% of low-cost FA.

Abstract

Purpose

The paper aims to investigate the level of student satisfaction with campus student housing facilities (SHF) at Malaysian research universities (RUs) and the relationship between satisfaction and loyalty behaviour.

Design/methodology/approach

The student residential satisfaction (SRS) framework has been proposed to investigate residential satisfaction from the students' viewpoint. Questionnaires were distributed to respondents in three RUs. The data were analysed using descriptive statistics.

Findings

In general, students are satisfied with the provided SHF with the SRS index of 2.96 or 74 per cent satisfaction level and there is a significant relationship between overall satisfaction and loyalty behaviour. The results also confirmed that the proposed model is an adequate instrument to measure SRS.

Practical implications

The existence of quality SHF is likely to act as an effective medium to attract local and international students to enrol in Malaysian universities. Further actions should be geared towards achieving a higher score of SRS index.

Originality/value

This paper introduces a practical model of SRS to be applied to universities in other countries with similar climate and culture.
