Abstract

Purpose

Deployment of deep neural networks on embedded devices is becoming increasingly popular because it can reduce latency and energy consumption for data communication. This paper aims to give out a method for deployment the deep neural networks on a quad-rotor aircraft for further expanding its application scope.

Design/methodology/approach

In this paper, a design scheme is proposed to implement the flight mission of the quad-rotor aircraft based on multi-sensor fusion. It integrates attitude acquisition module, global positioning system position acquisition module, optical flow sensor, ultrasonic sensor and Bluetooth communication module, etc. A 32-bit microcontroller is adopted as the main controller for the quad-rotor aircraft. To make the quad-rotor aircraft be more intelligent, the study also proposes a method to deploy the pre-trained deep neural networks model on the microcontroller based on the software packages of the RT-Thread internet of things operating system.

Findings

This design provides a simple and efficient design scheme to further integrate artificial intelligence (AI) algorithm for the control system design of quad-rotor aircraft.

Originality/value

This method provides an application example and a design reference for the implementation of AI algorithms on unmanned aerial vehicle or terminal robots.

Abstract

Purpose

This study aims to investigate the rising trend of virtual influencers – digitally created characters with human-like attributes. It aims to evaluate and compare their effectiveness with human influencers in terms of brand attitudes and purchase intentions. It uncovers the mechanisms underlying the differences in effectiveness observed between virtual influencers and their human counterparts.

Design/methodology/approach

The research uses a 2 (influencer type: human vs virtual) × 3 (product type: functional vs symbolic vs experiential) between-subjects design. Through a pilot study (n = 334) and a main study (n = 352), the research examines the interactive effects of influencer and product type on brand attitude and purchase intentions. Hypotheses were developed and tested using moderating mediation models centered on authenticity and product–endorser fit.

Findings

Virtual influencers are perceived as less authentic than human influencers across all product types, negatively influencing brand attitude and purchase intention. However, the extent to which influencer type affects brand attitudes and purchase intentions, mediated by product–endorser fit, varies based on the product type.

Originality/value

This research emphasizes two key mechanisms – authenticity and product–endorser fit – influencing the effectiveness of virtual influencers. It suggests that aligning virtual influencers with suitable product types can offset their perceived authenticity deficit, significantly affecting their endorsement effectiveness.

Abstract

Purpose

With growing concerns about users’ well-being on social media, research stresses the importance of threat appraisals as a crucial first step in motivating self-protective actions. This study, in view of the prevalence of parasocial relationships between followers and social media influencers, aims to unravel the complex dynamics of followers’ threat perceptions within these relationships. Specifically, it examines how factors such as perceived self-efficacy to disengage and the positive affect of social media use influence threat appraisals.

Design/methodology/approach

A theoretical model is proposed based on appraisal theory to examine the impact of parasocial relationships on threat perception in engagement. It is empirically tested with data from 186 Instagram users.

Findings

The study reveals an overall positive relationship between parasocial relationships and perceived threat. This relationship is moderated by followers’ perception of self-efficacy to disengage – followers with a high sense of self-efficacy to disengage experience a decrease in threat perception as their parasocial relationships strengthen, whereas followers with a low sense of self-efficacy to disengage report an increase in threat perception with higher levels of parasocial relationships. This interplay is pronounced when followers experience average or below-average levels of positive affect on social media but diminishes when the positive affect is high.

Originality/value

This work contributes insights into social media influencers, threat appraisal dynamics and digital well-being research. Bridging a critical gap in existing knowledge, the study identifies the pivotal roles of followers’ self-efficacy to disengage and positive affect in shaping their threat appraisals toward parasocial relationships with social media influencers. This not only advances theoretical frameworks but also enhances our understanding of the nuanced dynamics of user reactions to parasocial engagements. Our findings offer practical insights for researchers, practitioners and platform developers aiming to cultivate healthy and responsible social media engagement in the digital era, ultimately contributing to individual well-being.

Abstract

Purpose

Although multiple forms of governance mechanisms have been studied to address the opportunistic behavior in franchising, research has not shed light on franchise systems operating in emerging markets despite exponential growth in these markets. To address this gap, this study aims to test the direct effects of different governance mechanisms on franchisee’s opportunism and moderating effects of franchisee’s relationship satisfaction on the relationship between different governance mechanisms and franchisee’s opportunism.

Design/methodology/approach

Survey data from 151 franchise owners were used to test the conceptual model and research hypotheses. The confirmatory factor model and structural equation model were tested by using AMOS.

Findings

Findings suggest that formalization and solidarity in franchising relationships negatively affect franchise opportunism. By contrast, franchisees, who are otherwise satisfied with their franchisor, find centralization and formalization oppressive and, therefore, engage in opportunistic activities.

Research limitations/implications

The study makes important contributions related to franchising in emerging markets. It addresses opportunistic behavior by franchisees in emerging markets and the role played by different governance mechanisms in curbing such behavior. The study has some limitations related to its cross-sectional design and its focus on a single emerging country, among others.

Originality/value

This study is among the first to examine the role of governance mechanisms to address franchisee’s opportunism in an emerging market context. The study’s findings have important theoretical and practical implications for governance design in business-to-business relationships in emerging markets.

Abstract

Purpose

The purpose of this paper is to improve the efficiency of accident management from the angle of reducing highway accident response times while taking into account total daily work hours.

Design/methodology/approach

The authors developed a patrol beat scheduling model, which is formulated as a chance-constrained optimization model, with the objective of minimizing the sum of officer work hours. Along with the model, a simulation program was also developed to help evaluate the effectiveness of the model-generated beat schedule in terms of response times.

Findings

This study concluded that, first, the current manually designed beat schedule could be improved should the National Highway Police Bureau adopt the proposed model. Second, the total daily work hours of the model-generated schedule at the confidence level of 100 percent were 64 hours, 21 hours less than the average work hours recorded in the 2006 data, or about an improvement of 24 percent. Should the model be adopted, not only response times will be improved, the 24 percent reduction in work hours could be translated into a cut in personnel cost.

Research limitations/implications

The scheduling model and simulation program are both built upon one-year historical data whose accuracy and completeness is prerequisite.

Practical implications

The proposed model can be adopted by other public service agencies such as fire departments, or emergency service centers. By replacing the historical data used in the study with their own data, agencies can evaluate the efficiency of their existing schedule or generate various schedules based on institutional needs.

Originality/value

This model utilizes historical accident data to generate optimal beat schedule and evaluate the efficiency of such schedule. Similar models have not been found in other studies.

Abstract

Purpose

The historical city of Macao has recently become one of the world’s centres for tourism and gaming. But growing traffic congestion in its narrow and old road network, especially in the city’s historic centre, raises concerns about the city’s traffic pollution, environmental impacts and negative effects on residents’ and visitors’ health. The purpose of this study is to address the possibility of mitigating emerging environmental problems with urban design solutions.

Design/methodology/approach

A review and background of the city’s evolution, from a Mediterranean-style town in the sixteenth century to its present status as one of the highest population density cities in the world, is first undertaken. The paper then critiques the urban layout that conditions current traffic and pollution trends.

Findings

High levels of pollution of particulate matters are created by a mixture of circumstances related to tall buildings along narrow roads, especially in the historic centre’s San Ma Lou Avenue, that limit ventilation and trap pollution. Green solutions that are known to effectively mitigate this problem, as well as contribute to enhancing the area’s carrying capacity, are discussed.

Originality/value

The originality of this paper lies in its critique of the environmental impact of rapid and overwhelming tourism-oriented development on the quality of the urban environment. It advocates urban design solutions based on experiences from other global tourist cities that, if implemented, will not damage the historic centre’s built environment and will contribute to a more liveable city for residents and better experience for visitors.

Abstract

Purpose

This study aims to examine whether and how the effect of intimate relationships with micro-influencers on customer behaviour is interrupted by external cues such as sponsorship disclosures and negative electronic word-of-mouth (eWOM).

Design/methodology/approach

The study worked with Instagram micro-influences to conduct a vignette survey with four experimental scenarios.

Findings

The benefits of parasocial relationships (PSR) in enhancing customer engagement (CE), brand preference (BP) and purchase intention (PI) cannot be sustained in the presence of external interruptive cues. For micro-influencers, whilst sponsorship disclosures do not moderate the influence of PSR, customers are considerably sensitive to negative eWOM or when the two cues co-occur.

Originality/value

This study focusses on micro-influencers and investigates whether the follower–micro-influencer bond can be moderated by external cues including sponsorship disclosure and negative eWOM.

Abstract

Purpose

This purpose of this paper is to explain Macau’s successful pandemic response through an analysis of its social, political and economic landscapes. In particular, it focusses on the economic relief brought by casino capitalism in this era of COVID-19.

Design/methodology/approach

As mobility is highly restricted during the coronavirus pandemic, digital technologies have become central to ongoing social science research. Thanks to videoconferencing programmes such as Zoom, Facetime and WhatsApp, the author was able to carry out virtual interviews with 13 local people from different sectors of Macau in July 2020. In addition to in-depth interviews, the author also undertook an extensive review of the Macau government’s pandemic policies.

Findings

This paper argues that the Macau government’s swift and effective coronavirus policies are deeply intertwined with the urban fabric and political economy of the city’s casino capitalism, which endowed the government with surplus funds and an infrastructure that enabled the implementation of an array of strict measures that few other countries could afford to subsidise. Factors that have led to Macau’s extraordinarily low rates of COVID-19 infections and deaths include: competent leadership and the public’s high compliance with mandatory health measures; the generous benefits and financial support for citizens and businesses; and the compulsory quarantine required of all incoming travellers, who are lodged in hotel rooms left empty when casino tourists stopped coming. All of these measures have been made possible by a political economy backed by the peculiarities of casino capitalism and its resultant tax revenues.

Research limitations/implications

Future research could compare the case of Macau with other small but affluent economies (ideally economies that do not depend on the gambling industry) to ascertain the role of casino capitalism in building up economic resilience.

Originality/value

Although previous studies tend to emphasise the negative impacts of casino capitalism, this paper shows how tax revenues and infrastructure from the gambling industry can make a contribution to the host society in times of crisis.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Highlights

  1. I-eIB model tests the mechanism of influencer ads on consumers’ buying impulse.

  2. Consumers’ attitude towards influencer ads affects their urge to buy impulsively.

  3. Influencer credibility affects consumer attitude via celebrity effect as a mediator.

  4. Trust affects consumer attitude via perceived usefulness as a mediator.

  5. Entertaining ads help develop favorable consumer attitude.

Abstract

Purpose

The reform and opening-up of capital market is valued for promoting sustainable development, while its impact presented as the form of deregulation of short-selling on the green innovation of enterprises in developing countries remains unclear. The purpose of this study is to outline the significance of gradual reform of financial markets in developing countries for low-carbon transformation and provide implications for achieving carbon peaking and carbon neutrality goals.

Design/methodology/approach

Based on the green subdivided patent data and financial data of China’s A-share listed companies, this paper takes the implementation of securities margin trading program as a quasi-natural experiment and applies the difference-in-differences (DID) model to examine the impact of deregulation of short-selling constraints on the enterprises’ green transformation.

Findings

The findings reveal that the initiating securities margin trading program significantly enhances the green innovation performance of enterprises. These findings are valid after performing a series of robustness tests such as the parallel trend test, the placebo test and the methods to exclude other policy interference. Mechanism analyses demonstrate a two-faceted effect of the securities margin trading program on the green innovation of enterprises, in which short-selling policy increases the pressure on capital market deregulation and meanwhile induces the environmental protection investment. The heterogeneity results demonstrate that the impulsive effect imposed by securities margin trading program is more significant in experimental group samples with characteristics of lower financing constraints, belonging to heavy polluting industries and possessing better environmental supervision capability.

Originality/value

First, previous studies have focused on the impact of financial policies implemented by banking institutions on the green innovation of enterprises, but few literatures have explored the validity of relaxing short-selling restrictions or opening the capital market in the field of enterprise’s green transformation in developing country. From the view of securities market reform, this paper broadens the incentive and supervision effects of the relaxation of short-selling control on enterprise’s green innovation performance after the implementation of securities financing and securities lending policy in China’s capital market. Second, previous studies have explored the impact of command-and-control environmental regulations, as well as market-incentivized environmental regulations such as green finance, low-carbon pilots and environmental tax reform, on the green transition of enterprises. Recently the role of the securities market in the green development of enterprises has received more attention in academia. The pilot of margin financing and securities lending is essentially a market-incentivized regulatory tool, but there is few in-depth research on how it affects the green innovation of enterprises. This paper enriches the research on whether the market incentive financial regulation policy can contribute to the green transformation of enterprises under the Porter hypothesis. Third, some previous studies used the ordinary panel regression model to explore the impact of financial policy on enterprise’s innovation performance. However, due to the potential endogenous problems of the estimated model, it might get biased conclusions. Therefore, based on the method of quasi-natural experiment, this paper selects the margin trading pilot policy as an exogenous shock to solve the endogenous or reverse causality problem in traditional measurement model and applies the DID model to study the relationship between core indicator variables.
