Abstract

Purpose

The purpose of this paper is to examine the contours of police integrity among Chinese police officers. Specifically, this study explores how Chinese police evaluate integrity based on official policy governing interactions, discipline governing infractions, views of seriousness, and willingness to inform when others engage in misconduct.

Design/methodology/approach

In total, 353 police officers were surveyed representing those attending in-service training program at a Chinese police university in May 2015. Questionnaires containing 11 scenarios describing police misbehaviors were distributed to officers during classes.

Findings

There was a strong correlation between officers’ perceptions of rule-violation, misconduct seriousness, discipline, and willingness to report. Additionally, preliminary results suggest there exists a code of silence among Chinese officers, and that Chinese officers hold a lenient attitude toward the use of excessive force.

Research limitations/implications

This study utilizes a convenient sample, which restricts the generalizability of the results.

Practical implications

The results indicate the existence of code of silence among Chinese officers and their lenient attitude toward the use of excessive force.

Originality/value

Although there has been a growing body of research examining police integrity in both western democracies and transitional societies, China as the largest developing nation in the world and with a unique police system (falls somewhere between the centralized model and the integrated model) is understudied. This study addresses this gap in previous literature by exploring the contours of police integrity among Chinese police officers.

Abstract

Purpose

The purpose of this paper is to investigate the factors that influence consumers’ consumption behavior with regard to green aquatic products from a social cognitive theory perspective.

Design/methodology/approach

A web survey was used to collect the data. The survey subjects were citizens of Ningbo City in Zhejiang Province. A total of 403 subjects were obtained through the sampling service, and 337 subjects were retained after strict examination. The data were used to construct a partial least squares structural equation model.

Findings

The cognition of green aquatic products significantly positively affects outcome expectancy, self-efficacy, perception of others’ behavior, and socio-structural conditions. Self-efficacy and outcome expectancy significantly positively influence consumption intention. Self-efficacy, perception of others’ behavior, and consumption intention significantly positively affect consumption behavior.

Practical implications

The concept, connotations and benefits of green aquatic products should be widely publicized through diversified channels to increase people’s knowledge of these products and to encourage people to distinguish them from regular aquatic products and to believe in their benefits. In addition, measures should be taken to guarantee that only genuine green aquatic products can enter the market because the false claims of some products have damaged consumers’ belief in these products.

Originality/value

To test the effect of the cognition of green aquatic products, the construct “the cognition of green aquatic products” was added to the model based on social cognitive theory. This paper contributes to the existing literature by further exploring how cognitive aspects affect consumption behavior with regard to green food.

Abstract

Purpose

This paper aimed to introduce a systematic body of knowledge via a scientometric review, guiding the sustainable transition from conventional construction to prefabricated construction. The construction industry currently faces a challenge to balance sustainable development and the construction of new buildings. In this context, one of the most recent debates is prefabricated construction. As an emerging construction approach, although existing knowledge makes contributions to the implementation of prefabricated construction, there is a lack of a comprehensive and in-depth overview of the critical knowledge themes and gaps.

Design/methodology/approach

This study uses the scientometric analysis to review the state-of-the-art knowledge of prefabricated construction. It retrieved data from the Web of Science core collection database. CiteSpace software was used to conduct the analysis and visualization; three analysis methods identify the knowledge hotspots, knowledge domains and knowledge topics. Finally, according to integrating the hidden connections among results, a body of knowledge for prefabricated construction application can be inferred.

Findings

The results show that 120 knowledge hotspots, five critical knowledge domains and five prominent knowledge topics are vital for promoting implementation of prefabricated construction. Based on the afore analysis, a body of knowledge for prefabricated construction that can systematically cover a broad knowledge of prefabricated construction-related research and activities are integrated and proposed in this paper.

Originality/value

Body of knowledge systematically covers a broad knowledge of prefabricated construction applications and is vital to guide researchers and practitioners to conduct related research and activities, thereby promoting the sustainable transition to prefabricated construction implementation.

Abstract

Purpose

The purpose of this paper is to develop an effective approach to significantly improve the thermomechanical properties of shape memory polymer (SMP) nanocomposites that show fast thermally responsive shape recovery.

Design/methodology/approach

Hexagonal boron nitrides (h-BNs) were incorporated into polymer matrix in an attempt to improve the thermal conductivity and thermally responsive shape recovery behaviour of SMP, respectively. Thermally actuated shape recovery behaviour was recorded and monitored instrumentally.

Findings

The results show that both glass transition temperature (Tg) and thermomechanical properties of the SMP nanocomposites have been progressively improved with increasing concentration of h-BNs. Analytical results also suggest that the fast-responsive recovery behaviour of the SMP nanocomposite incorporated with h-BNs was due to the increased thermal conductivity.

Research limitations/implications

A simple way for fabricating SMP nanocomposites with enhanced thermally responsive shape recovery based on the incorporation of h-BNs was developed.

Originality/value

The outcome of this study may help fabrication of SMP nanocomposites with fast responsive recovery behaviour.

Abstract

Purpose

Proper assessment of contractors' competitiveness is important for assisting contractors in taking internal analysis and for assisting clients in selecting suitable contractors. This paper seeks to address this issue.

Design/methodology/approach

With previously identified contractor key competitiveness indicators (KCIs), this study presents a fuzzy competitiveness rating (FCR) method for measuring contractor competitiveness with reference to the Hong Kong construction industry. A set of linguistic terms is used for facilitating the assessment process.

Findings

For illustration, an example is used to show the application of the FCR method. The results provide valuable information for helping contractors in the local construction industry to understand their competitive advantages and weaknesses, and to formulate effective competition strategies to improve their competitiveness.

Research limitations/implications

The model used in this study is not validated by real cases. In a future paper, the model will be further demonstrated by conducting real case studies, and the linguistic terms and corresponding fuzzy numbers will also be re‐defined based on the collected data.

Originality/value

As the competitiveness assessment process involves complexity and uncertainty, a fuzzy competitiveness rating method is considered suitable for reflecting the reality and the assessment panel can easily give their opinions by using the linguistic language.

Abstract

Purpose

This study aims to identify senior citizens’ requirements related to “embedded retirement facilities (ERFs)”, which are small-scale, multi-functional and community-based care facilities for senior citizens in mainland China, and to discuss whether senior citizens’ perceptions are influenced by their backgrounds.

Design/methodology/approach

A questionnaire type of research was administrated to gain senior citizens’ rankings of services that should be provided by ERFs. Non-parametric statistical models were applied to analyse the collected data.

Findings

Results reveal that health care services for senior citizens are considered the most important. Requirements regarding rehabilitation and entertainment and daily life assistance are ranked second and third, respectively. Culture-related activities are the least important. Differences in the senior citizens’ background also influence their choices.

Research limitations/implications

This research is based on a questionnaire survey completed in northeast China. Opinions from other areas of mainland China will be collected in the future study. Furthermore, the key items identified in this research, which was completed by participants from the built environment discipline, can be further elaborated by combining interdisciplinary feedback.

Practical implications

This study explores services that are supposedly provided by ERFs. Findings will provide useful perceptions from senior citizens and will enable decision makers to prioritise services for senior citizens.

Social implications

Although senior citizens are the end users of ERFs, their needs are easily overlooked. This study calls attention to their needs from ERFs, and the results are likely to serve as references for stakeholders in building improved facilities.

Originality/value

ERFs have been provided in mainland China to cater to senior citizens’ needs since 2014. However, few studies have identified senior citizens’ requirements for provided services. The survey-based results of this work will serve as references for various stakeholders in making enhanced decisions.

Abstract

Purpose

The purpose of this paper is to provide a review of recent systematic and comprehensive advancement in electrospun polymer fiber and their composites with shape memory property.

Design/methodology/approach

The nanofiber manufacture technique is initially reviewed. Then, the influence of electrospinning parameters and actuation method has been discussed. Finally, the study concludes with a brief review of recent development in potential applications.

Findings

Shape memory polymer (SMP) nanofibers are a type of smart materials which can change shape under external stimuli (e.g. temperature, electricity, magnetism, solvent). In general, such SMP nanofibers could be easily fabricated by mature electrospinning technique. The nanofiber morphology is mainly affected by the electrospinning parameters, including applied voltage, tip-to-collector distance, viscosity of solution, humidity and molecular weight. For actuation method, most SMP nanofibers and their composites can change their shapes in response to heat, magnetic field or solvent, while few can be driven by electricity. Compared with the block SMPs, electrospun SMP nanofibers’ mat with porosity and low mechanical property have a wide potential application field including tissue engineering, drug delivery, filtration, catalysis.

Originality/value

This paper provides a detailed review of shape memory nanofibers: fabrication, actuation and potential application, in the near future.

Abstract

Purpose

The “multi‐criteria selection” has become popular practice in selecting contractors, especially for public works, which involve multiple stakeholders. In line with this development, contractors need to consider more factors apart from offering a lower bidding price in formulating a bidding strategy. The purpose of this paper is to introduce a quantitative method, namely the fuzzy competence requirement (FCR) model, for assisting a contractor to formulate a better bidding strategy by better utilising its competence for meeting the best multiple criteria imposed by clients.

Design/methodology/approach

The fuzzy linear programming with multiple objectives technique is applied in this paper and an illustrative example is introduced to demonstrate the application of the proposed model.

Findings

The FCR model can assist in generating a range of bidding strategies by assuming different confidence levels that contractors may perceive. These strategies could be valuable references for contractors to develop their competitive bidding strategy, which enables contractors to efficiently utilise their competence to meet clients' multiple selection criteria.

Research limitations/implications

The FCR model can provide contractors with useful information for formulating their bidding strategy. However, other factors, such as the sense of the market and estimation of rivals' bidding strategy, should also be considered in the bidding decision.

Practical implications

The FCR model can help contractors make better decisions in bidding by considering their competence and meeting client's multiple criteria.

Originality/value

This paper introduces a new model – FCR model – for helping contractors improve the efficiency of their bidding decision.

Abstract

Purpose

This study aims to identify the stakeholders and critical factors (CFs) of promoting age-friendly communities (AFCs), discuss the relationship between the stakeholders and CFs and develop a preliminary framework for the briefing stage of promoting AFCs in urban China.

Design/methodology/approach

Stakeholders and CFs were identified through literature review and document analysis. The Delphi method was used to screen the extracted stakeholders and CFs. The focus group methodology was applied to obtain evaluation matrices of relationships between stakeholders and CFs. A two-mode social network was formed to analyse the evaluation matrices generated.

Findings

Results of the analyses indicate that local governments and policymaking institutions, together with project investors, obtained high prioritisations in the stakeholders' group, whilst senior citizens and caregivers appear to rank last. For CFs, communities' environmental factors receive the most attention from stakeholders.

Research limitations/implications

Results of the analyses can only show similarities of the participating stakeholders' opinions on their concerns, and provide researchers and practitioners with initial ideas on analysing stakeholders and CFs at the briefing stage of promoting AFCs. For a specific project, the concerns and prioritisations would change. Diverse voices are necessary and case studies are in need.

Practical implications

Challenges in promoting AFCs in urban China are discussed, and a preliminary framework of the briefing stage is developed for practitioners to follow when promoting AFCs.

Originality/value

This study discusses which CFs should be considered priorities and what consensuses are generally reached by stakeholders. CFs are utilised to interpret stakeholders' relationships, influences and concerns on AFC projects when conducting the social network analysis (SNA).

Abstract

Purpose

The purpose of this paper is to developing a kind of acoustic metamaterial with wide frequency band especially in low frequency region. At the same time, its the tunability of sound insulation frequency is achieved.

Design/methodology/approach

A three-dimensional (3D) acoustic metamaterial consisting of rigid frame, spherical attachment and thin film is proposed. The material parameters and the effect of the attachment hole on the forbidden band are investigated by finite element simulation. The sound insulation effect of the structure is validated by the combination of simulation and experiment.

Findings

The results show that the elastic modulus of the structural material determines the initial frequency of the forbidden band of the proposed 3D acoustic metamaterials. The lower the elastic modulus of the structural material, the lower the initial frequency of the forbidden band. The material parameters of the frame mainly affect the initial frequency of the first forbidden band, and the material parameters of the attachment will affect both the initial and termination frequency of the first forbidden band. Holes in the attachments reduce the band gap width. The characteristic curve moves down with the increase of subtracted mass.

Research limitations/implications

The findings may greatly benefit the application of the acoustic metamaterials in the fields of sound insulation and noise reduction.

Originality/value

This acoustic metamaterial structure has excellent sound insulation performance. At the same time, the single cell structure can be assembled into any shape. The structure can achieve sound selective filtering and combination control.
