E-commerce live streaming is a new influencer advertising method that allows influencers to interact directly with consumers on e-commerce platforms. Although evidence suggests that influencer live-streaming advertisements (ads) on social media can increase consumers’ buying impulses, little research examined how this similar but new advertising method on e-commerce platforms may influence consumers’ urge to buy impulsively. This study explores the role of influencer credibility, celebrity effect, perceived entertainment, trust and perceived usefulness on consumers’ attitudes toward influencer ads and their urge to buy impulsively.

A questionnaire containing seven constructs was developed and distributed to participants using a convenient sample and snowball sampling approach. The constructs were measured based on validated measurement items from the literature and adjusted according to this study’s focus. A total of 236 valid responses were obtained from the survey and used for data analysis. A partial least squares structural equation modeling approach was employed for parameter estimation and model testing.

The empirical results show that all constructs influenced consumers’ urge to buy impulsively via attitude toward influencer ads. The proposed research model explains 61.7% of the variance in attitude toward influencer ads and 19.4% of the urge to buy impulsively.

This is an early study investigating the relationship between influencer advertising and impulse buying. The results provide valuable insights into improving the design of influencer ads and marketing strategies.

Creative Design was a start-up company in Taiwan. To fulfill a course requirement while she was still in school, the founder had formed a team and entered an entrepreneurship competition. They won the second runner up award in that competition and impressed some firms who enquired if they would be interested in doing corporate identity system (CIS) design. They discovered that without establishing a corporate structure their prospective clients would be unable to pay an invoice. As a consequence, the founder and one of the team members established Creative Design Ltd. This case discusses the challenge Creative Design faced at the end of 2012. Wonderland farmers’ association (WFA) wanted to market locally grown jasmine but did not know how to go about it. They reached out to the founder and her company for assistance. The case of WFA was uncharted territory. Creative Design already had extensive experience in CIS design, but it did not have any experience in handling agriculture products. In this case, they had to deal with the full supply chain from production to exhibition. The risk for this project was high but Creative Design accepted the case and became the first design firm offering a “total solution.” Currently, Creative Design works with all kinds of cases, from simple CIS designs to more complicated total solutions of various scales. The founder now has to contemplate if the design house should develop more total solution cases. Doing so would require recruiting more staff and the dilemma of balancing revenue and costs.

The case study is designed for the undergraduate and graduate students of the College of Management; the case can be adopted for the courses of management, innovation and entrepreneurship, etc.

Robot-assisted system for minimally invasive surgery (MIS) has been attracting more and more attentions. Compared with a traditional MIS, the robot-assisted system for MIS is able to overcome or reduce defects, such as poor hand-eye coordination, heavy labour intensity and limited motion of the instrument. The purpose of this paper is to design a novel robotic system for MIS applications.

A robotic system with three separate slave arms for MIS has been designed. In the proposed robot, a new mechanism was designed as the remote centre motion (RCM) mechanism to restrain the movement of instrument or laparoscope around the incision. Moreover, an improved instrument without coupling motion between wrist and grippers was developed to enhance its manipulability. A control system architecture was also developed, and an intuitive control method was applied to realize hand-eye coordination of the operator.

For the RCM mechanism, the workspace was analyzed and the positioning accuracy of the remote centre point was tested. The results show that the RCM mechanism can be applied to MIS. Furthermore, the master-slave trajectory tracking experiments reveal that slave robots are able to follow the movement of the master manipulators well. Finally, the feasibility of the robot-assisted system for MIS is proved by performing animal experiments successfully.

This paper offers a novel robotic system for MIS. It can accomplish the anticipated results.

The purpose of this paper is to devise a simple but practical model to assist decision makers in evaluating the tariff stability of concession schemes.

To develop such a model necessitates the identification of parameters that could contribute to an increase or decline in investment return. With that a Monte‐Carlo‐based simulation model is devised to determine the probability that the tariff regime remains unchanged even when the identified risks do occur at the operational stage. Sensitivity analysis is performed to identify the most influential factors to investment return and tariff stability.

The results of the scenario indicate that the internal rate of return could be profoundly influenced by the risk factors which reaffirm the needs for a more comprehensive model for tariff stability evaluation.

Through the simulation model, a tariff stability indicator is derived and when integrated with the results of sensitivity analysis this could generate a weighted indicator for alternative tariff regimes for use in decision support systems.

With the aid of simulation techniques, decision makers can predict the impact of a range of possible market conditions and/or levels of demand on the investment return and hence the stability of the tariff regime.

The model could be extended to other types of public‐private partnerships schemes upon suitable adjustment

Remotely piloted aircraft (RPA) systems have emerged as an established tool within the construction industry. Concurrent with this trend has been the rise in research on RPA, establishing this as a new field of study within the construction management domain. What is needed now is an assessment of the current state of research in this emerging discipline – its strengths and weaknesses – by which future research on RPA in construction may be guided. The purpose of this paper is to address this need.

A total of 59 peer-reviewed journal articles covering RPAs within the construction domain were systematically reviewed using a mixed-methods approach, utilizing qualitative-scientometric analyses techniques.

The results reveal a field of study in its fledgling stage, with a limited number of experts operating somewhat in isolation, from a limited number of institutions. Key publication outlets are identified, with the main focus of research being in the technical areas of remote sensing, photogrammetry and image processing.

The study benefits researchers and industry practitioners alike. For researchers, the identified gaps reveal areas of high priority in future research. For construction companies, particularly small to medium-sized businesses, the study raises awareness of the latest developments and potential applicability of RPAs in the industry.

The study exposes what is missing from current research: a broader consideration of organizational adjustments needed to accommodate RPA usage, economic analyses and impediments to wider acceptance.

The paper analyzes downside and upside risk spillovers between stock markets of G7 countries and China before and during the COVID-19 pandemic.

By using VAR-ADCC models and conditional value at risk (CoVaR) techniques, downside and upside risk spillovers between stock markets of G7 countries and China are analyzed before and during the COVID-19 pandemic.

The results suggested existence of a significant and asymmetrical two-way risk transmission between majority of pair markets, but the degree of asymmetry differs according to the use of the entire cumulative distributions or distribution tails. Downside and upside risk spillovers are significantly larger before the COVID-19 pandemic in all cases except between CAC 40/DAX and S&P/SSE pairs.

The paper used CoVaR and delta-CoVaR to investigate the downside and upside spillovers between stock markets of G7 countries and China before and during the COVID-19 pandemic.

Over the past decade, researchers have used unmanned aerial systems (UASs) in construction industry for various applications from site inspection to safety monitoring or building maintenance. This paper aims to assort academic studies on construction UAS applications, summarize logics behind using UAS in each application and extend understanding of current state of UAS research in the construction setting.

This research follows a systematic literature assessment methodology to summarize the results of 54 research papers over the past ten years and outlines the research trends for applying UASs in construction.

UASs are used in building inspection, damage assessment, site surveying, safety inspection, progress monitoring, building maintenance and other construction applications. Cost saving, time efficiency and improved accessibility are the primary reasons for choosing UAS in construction applications. Rotary-wing UASs are the most common types of UASs being used in construction. Cameras, LiDAR and Kinect are the most common onboard sensors integrated in construction UAS applications. The control styles used are manual, semi-autonomous and autonomous.

This paper contributes to classification of UAS applications in construction research and identification of UAS hardware and sensor types as well as their flying control systems in construction literature.

This paper aims to theoretically and empirically demonstrate the role played by business continuity management (BCM) to address risks such as trade conflicts and natural disasters. This paper also answers whether compliance with international standards such as the International Organization for Standardization (ISO) 22301 is adequate.

A case study of Chinese telecommunications giant Huawei is conducted to examine how a robust end-to-end BCM system has been established in two decades and in what way it has helped Huawei to efficiently maintain growth under pressure, such as being added to the “Entity List” and the pandemic.

Huawei case contributes to BCM theory in its approach to establishing the BCM system and its well-established BCM model. Huawei establishes and continually improves its BCM system by applying the Plan (establish), Do (implement and operate), Check (monitor and review) and Act (maintain and improve) cycle. Characterized as 4Ps: BCM policy, BCM process, incident management plan and business continuity plan, Huawei BCM system is shaped into a loop with end-to-end BCM process, covering all steps along its value chain – from suppliers and partners to Huawei itself and then on to its customers – with key initiatives for all domains such as R&D, procurement, manufacturing, logistics and global technical services. In practice, implementing international standards such as ISO 22301 enables Huawei to develop business continuity but not enough. Optimizing the BCM system is an ongoing effort, and BCM maturity is ever present: continually improving Huawei’s own BCM system and benchmarking against best practices available worldwide.

Apart from the case study, other methods such as counter-factual analysis can be used to further test whether Huawei’s BCM system is cost-effective. Another direction for future study is whether suggested BCM maturity levels should be supplemented into ISO 22301. In the digital age, how to use digitalization to ensure business continuity is a current issue not just for practitioners such as Huawei but also for researchers worldwide.

In practice, implementing international standards such as ISO 22301 enables Huawei to develop business continuity but not enough. Optimizing the BCM system is an ongoing effort, and BCM maturity is ever present: continually improving Huawei’s own BCM system and benchmarking against best practices available worldwide.

To the best of the authors’ knowledge, this is one of the first studies to focus on how an organization continually improves the suitability, adequacy and effectiveness of its BCM system, with special attention to standards compliance.

The purpose of this paper is to investigate the development process of the fire whirl in the fixed-frame facility and focus on the impacts of the fire whirl’s vortex core on the formation and flame structure of the fire whirl.

The complex turbulent reacting flame surface is captured by the large eddy simulation turbulence closure coupled with two sub-grid scale (SGS) kinetic schemes (i.e. the chemistry equilibrium and steady diffusion flamelet). Numerical predictions are validated thoroughly against the measurements by Lei et al. (2015) with excellent agreements. A double maximum tangential velocity refinement approach is proposed to quantify the vortex cores’ instantaneous location and region, addressing the missing definition in other studies.

The numerical results show that the transition process of the fire whirl is dominated by the vortex core movement, which is related to the centripetal force. The unsteadiness of the fully developed fire whirl was found depending on the instantaneous fluctuation of heat release rate. The steady diffusion flamelet scheme is essential to capture the instantaneous fluctuation. Furthermore, the axial velocity inside the vortex core is the key to determining the state of fire whirl.

Due to intensive interactions between buoyant fires and ambient rotating flow, the on-set and formation of fire whirl still remain largely elusive. This paper focused on the transition process of fire whirl between different development stages. This paper provides insights into the transition process from the inclined flame to the fire whirls based on the centripetal force.

This paper presented and compared two SGS kinetic schemes to resolve the fire whirl development process and the unsteadiness of its vortical structures. The modelling framework addresses the shortcoming of previous numerical studies where RANS turbulence closure and simplified combustion kinetics was adopted. Numerical results also revealed the fire whirl transition process and its relationship to centripetal force.

Driving cycle is an essential requirement to evaluate the exhaust emissions of various types of vehicles on the chassis dynamometer test. This study presents a real world comparison of the driving cycles of Edinburgh motorcycles in two world cities; Edinburgh in Scotland and Delhi in India. The two driving cycles (EMDC & DMDC) driving cycle (EMDC) that were was developed through the analysis of experimental data. This data was collected from trips on a number of routes in each city. In Edinburgh, five different routes between the home addresses in the surrounding areas and place of work at Edinburgh Napier University in Edinburgh were selected. In Delhi data were collected in East Delhi (Geeta Calony) to Central Delhi (Raisena Road). The data collected data was divided into two categories of urban and rural roads in the case of Edinburgh while it was only the urban route in Delhi.. Forty four trips were made on the five designated routes in both urban and rural areas and 12 trips were made in Delhi. The aims of the study were to assess the various parameters (i.e. motorcycle speed, cruise, accelerations and decelerations and percentage time spent in idling) and their statistical validity over total trip lengths for producing a real world EMDC in each of the two cities. The results show that EMDC in Edinburgh, the EMDC has a cycle length of 770 and 656 seconds for urban and rural trips, respectively, which was found more than ECE cycle length. Time spent in acceleration and deceleration modes were found to be significantly higher than any other driving cycle reported to date for motorcycles, reflecting a typical characteristic of the driving cycle in Edinburgh; this was presumably due to diverse driving conditions of motorcycles in the city. In Delhi on the other hand, the DMDC has a cycle length of 847.5 seconds for the urban trips, which higher than that of the EMDC length. The overall percentage time spent in acceleration in Delhi was higher than that of Edinburgh while the time spent in deceleration was lower in Delhi. The overall average speed in the case of Delhi was slightly higher than that of Edinburgh.
