This study aims to establish an evaluation method for cross-regional major infrastructure project (CRMIP) supportability. The focus is to identify evaluation indicators from a complexity perspective and develop an evaluation model using qualitative and quantitative methods. Case studies are carried out to verify the reliability of the evaluation model, thereby providing theoretical and practical guidance for CRMIP operations and maintenance (O&M).

Guided by the idea of complexity management, the evaluation indicators of CRMIP supportability are determined through literature analysis, actual O&M experience and expert interviews. A combination of qualitative and quantitative methods, consisting of sequential relationship analysis, entropy weighting, game theory and cloud model, is developed to determine the indicator weights. Finally, the evaluation model is used to evaluate the supportability of the Hong Kong–Zhuhai–Macao Bridge (HZMB), which tests the rationality of the model and reveals its supportability level.

The results demonstrate that CRMIPs' supportability is influenced by 6 guideline-level and 18 indicator-level indicators, and the priority of the influencing factors includes “organization,” “technology,” “system,” “human resources,” “material system,” and “funding.” As for specific indicators, “organizational objectives,” “organizational structure and synergy mechanism,” and “technical systems and procedures” are critical to CRMIPs' O&M supportability. The results also indicate that the supportability level of the HZMB falls between good and excellent.

Under the guidance of complexity management thinking, this study proposes a supportability evaluation framework based on the combined weights of game theory and the cloud model. This study provides a valuable reference and scientific judgment for the health and safety of CRMIPs' O&M.

The purpose of this paper is to integrate the Quality–Loyalty Model and the Religiosity–Loyalty Model to assess loyalty formation toward Halal food.

Data from 320 respondents were collected in Bandung Indonesia through a survey. A partial least-square modeling was employed to evaluate the association between food quality, religiosity, perceived value, satisfaction and loyalty.

This study discloses that the two integrated loyalty models are fit, indicating that incorporating these loyalty models provides a better comprehension of loyalty toward Halal food. Further, this study confirms the importance of both food quality and religiosity in determining loyalty.

This research offers an important finding for Halal food managers to develop customer loyalty through food quality and religiosity. This research recommends that Halal food managers, besides obtaining Halal certification, need to constantly innovate and adopt world food-quality standards to deal with customers’ constantly changing demands.

This research is the first that integrates the Quality–Loyalty Model and the Religiosity–Loyalty Model to get a better understanding of loyalty formation toward Halal food.

The purpose of this paper is to develop high-performance Au-coated Ag alloy wires (ACAA wires) and demonstrate the effect of Au coating layers on the bonding performance and oxidation resistance for stable and reliable electronic packaging applications.

ACAA wire with a diameter of approximately 25 µm and Au layer thickness of approximately 100 nm were prepared by the continuous casting, plating and wire drawing method. The bonding performance of the ACAA wires were studied through bonding on 3,535 chips. The oxidation resistance of ACAA wires and Ag alloy wires (AA wires) were comparatively studied by means of chemical oxidation tests, accelerated life tests and electrochemical tests systematically.

ACAA wires could form axi-symmetrical spherical free air balls with controllable diameter of 1.5∼2.5 times of the wire diameter after electric flame-off process. The ball shear strength of ACAA wire was higher than that of AA wires. Most importantly, because of the surface Au coating layer, the oxidation resistance of ACAA wires was much enhanced.

ACAA wires with different lengths of heat affected zone were not developed in this study, which limited their application with different loop height requirements.

With higher bonding strength and oxidation resistance, ACAA wires would be a better choice than previous reported AA wire in chip packaging which require high stability and reliability.

This paper provides a kind of novel ACAA wire, which possess the merits of high bonding strength and reliability, and show great potential in electronic packaging applications.

The purpose of this paper is to examine the inclusive leadership’s too-much-of-a-good-thing effect (TMGT effect) and illustrate the possibility of the potential drawbacks of inclusive leadership.

In total, 191 questionnaires were valid and used in the study. Employee participants were asked to report their direct supervisor’s inclusive leadership. Employees’ direct supervisors were asked to rate employees’ task performance to minimize common method variance. The authors use regression analysis to test the hypothesis.

An inverted U-shape characterizes the relationship between inclusive leadership and subordinates’ task performance. Specifically, employees’ task performance is low when the supervisor’s inclusive leadership is low; task performance increases when inclusive leadership is from low to moderate levels, and task performance decreases when inclusive leadership is from moderate to high levels.

The study sheds light on inclusive leadership, especially the inclusive leadership in Chinese context. In addition, this finding is important as it investigates the inclusion’s TMGT effect which is rare in organizational research, and the findings also provide additional evidence of TMGT effect in management fields.

The paper is aimed to avoid the situation that historical relics are encroached, isolated and fragmented because of cities in the rapid urban process. Taking the environment around the Qinglong Temple in Xi'an city as an example and based on the characteristics of urban patterns in the history, this paper explores the spatial connection relationship between historical relics and surrounding villages as well as the connection between metro traffic and commercial bodies. At the end of the paper, the improvement strategy is put forward, namely the design concepts of “stepwise style” and “landscape style”, which can be achieved by the demand of ecological restoration and the relationship between urban axis. To be noted, the research shows, by restructuring new connection space, the city can promote the urban memory to be restored, the urban appearance to be reshaped, and the urban patterns in the history to be respected and displayed.

This study aims to examine how aid for trade policy and regulations (AfTPR) contribute to achieving Sustainable Development Goal (SDG) target 8.1 (sustain per capita economic growth) and whether the effectiveness of AfTPR is conditional to the stable political environment.

This paper uses a widely accepted endogenous growth framework and applies panel data fixed effects and two-step difference and system generalized method of moments estimation strategies on panel data of 50 developing countries over 2005–2017.

The findings of the study confirm that aid to trade policy promotes sustainable economic growth in developing countries, but this category of development assistance is only effective and significant for low and lower middle-income (LLMI) economies. The positive and significant effect of AfTPR in upper middle-income countries is conditional to their level of political stability. Under a stable political situation, the positive effect of AfTPR on sustainable growth remains almost same for the LLMI countries, whereas for the upper middle-income countries this growth effect reached almost double.

International trade is considered as a driver for inclusive and sustainable economic growth, whereas aid for trade is acknowledged for its prospective contribution toward achieving these goals. The findings have dominant policy implications for the international development organizations and donors, which recommend that it is more desirable to transmit aid toward developing and implementing trade policy and regulations as per capita economic growth improves in the aid recipient countries.

According to the authors’ knowledge, no prior study empirically analyzes the effect of AfTPRs on SDG target 8.1.

The purpose of this study is to investigate whether aggregate and sectoral disbursement of aid for trade (AfT) facilitates achieving gender equality and women empowerment in aid-recipient developing countries for the period 2005–2019.

The study develops static and dynamic panel data and empirical specifications and employs fixed effects and generalised method of moments (GMM) estimation techniques to estimate the impact of aggregate AfT and different categories of AfT on women empowerment. The study uses the Gender Inequality Index (GII) and Global Gender Gap Index (GGI) as the proxy measures of SDG-5, where the higher (lower) value of GII (GGI) implies higher gender disparities and lower women empowerment, and vice versa.

The study finds that aggregate AfT and aid disbursement for the development of economic infrastructure, productive capability building and trade policy and regulations contribute significantly to achieve women empowerment by reducing gender inequalities concerning the labour force and political participation, education enrolment and better healthcare and by increasing gender gap index in relation to economic participation, educational attainment, health and survival and political empowerment. The impact of aggregate AfT and its different categories is found significant only in low- and lower-middle-income developing countries. The findings also indicate that the impact of AfT is not noticeably different across different regions of the world as well as the religious belief of the developing countries.

The study recommends that more allocation of gender-responsive AfT, whether aggregated or disaggregated, significantly helps women empowerment and assists developing economies to achieve SDG-5.

This study is one of the few that investigate the impact of aggregate AfT on gender inequality and women empowerment. This is the foremost study that examines the effects of each individual category of AfT on women empowerment vis-à-vis SDG-5.

This paper aims to exploit shape memory polymer (SMP) composite as multifunctional coatings for protecting substrates from surface wear and bacterial. The efficiency of added nano or micro-sized particles in enhancing the properties of SMP was investigated. This study also attempts to use a low-cost and effective spraying approach to fabricate the coatings. The coatings are expected to have good conformability with the substrate and deliver multi-functional performance, such as wrinkle free, wear resistance, thermal stability and antimicrobial property.

High-performance SMP composite coatings or thin films were fabricated by a home-made continuous spray-deposition system. The morphologies of the coatings were studied using the scanning electron microscope and the transmission electron microscope. The abrasion properties were evaluated by Taber Abraser test, and thermo-gravimetric analysis was carried out to investigate the thermal properties of prepared composites. The antimicrobial property was determined by the inhibition zone method using E. coli. The thermally responsive shape memory effect of the resulting composites was also characterized.

The morphology analysis indicated that the nanoclay was distributed on the surface of the coating which resulted in a significant improvement of the wear property. The wear resistance of the coatings with nanoclay was improved as much as 40 per cent compared with that of the control sample. The thermo-gravimetric analysis revealed that the weight loss rate of composites with nanoclay was dropped over 40 per cent. The SMP coating with zinc oxide (ZnO) showed excellent antimicrobial effect. The shape recovery effect of SMP/nanoclay and SMP/ZnO composites can be triggered by external heating and the composites can reach a full shape recovery within 60 s.

This study proposed a continuous spray-deposition fabrication of SMP composite coatings, which provides a new avenue to prepare novel multi-functional coatings with low cost.

Most studies have emphasized on the sole property of SMP composites. Herein, a novel SMP composite coating which could deliver multi-functionality such as wrinkle free, wear resistance, thermal stability and antimicrobial property was proposed.

This study investigates the recycling attitudes and behaviour of university students and staff members, and suggests ways to improve environmental policies and recycling facilities in a university campus.

This study applies the theory of planned behaviour, through which it develops an instrument to measure the determinants of recycling behaviour among the people in a university campus. A survey was designed and administered at a public university in Hong Kong; 205 valid responses from 179 students and 26 staff members were collected. A partial least squares approach was used to validate the proposed model. This model accounted for the 42.1 per cent and 50.3 per cent variance (R²) in behavioural intention and behaviour, respectively, vis‐à‐vis recycling activities.

The survey results suggested that behavioural intention with regard to recycling is influenced by attitude, the subjective norms, perceived behavioural control, awareness of consequences, the moral norms, and convenience. Educational and promotional programmes highlighting the benefits and importance of recycling activities and convenience of the recycling facilities can be adopted as the key strategies to encourage recycling on campus.

The unique culture in relation to recycling in the specific campus environment and the nature of the sample might limit the generalisability of the results to other areas and contexts. The self‐report‐based measures adopted in this study might lead to a social desirability bias in the results provided by the respondents.

The findings provide insightful information for universities and the wider community to shape a more user‐friendly and convenient recycling scheme. This can fulfil the actors' social responsibility.

The purpose of this paper is to explore how to use social media in e-government to strengthen interactivity between government and the general public.

Categorizing the determinants to interactivity covering depth and breadth into two aspects that are the structural features and the content features, this study employs general linear model and ANOVA method to analyse 14,910 posts belonged to the top list of the 96 most popular government accounts of Sina, one of the largest social media platforms in China.

The main findings of the research are that both variables of the ratio of multimedia elements, and the ratio of external links have positive effects on the breadth of interactivity, while the ratio of multimedia features, and the ratio of originality have significant effects on the depth of interactivity.

The contributions are as follows. First, the authors analyse the properties and the topics of government posts to draw a rich picture of how local governments use the micro-blog as a communications channel to interact with the public. Second, the authors conceptualize the government online interactivity in terms of the breadth and depth. Third, the authors identify factors that will enhance the interactivity from two aspects: structural features and content features. Lastly, the authors offer suggestions to local governments on how to strengthen the e-government interactivity in social media.
