This article focuses on students' perspectives on various aspects of learning science at a distance, such as ‘expectations,’ ‘learning outcomes,’ and ‘satisfaction’. Two foundation science courses offered by the School of Science and Technology at the Open University of Hong Kong (OUHK) were selected for the study. A series of indepth interviews was carried out with students enrolled in these courses, followed by questionnaire surveys and field observations in order to validate and triangulate the interview data. The findings revealed that students placed a high value on practical work in science courses. Moreover, the more familiar with the course subject, the less difficulty they anticipate in learning science via distance education. Two significant correlations were also found, between the perception of practical work and satisfaction, and between the attendance rate and the perception of practical work with distance learning at OUHK. This research adds to knowledge of disciplinebased distance education research in terms of empirical data in both qualitative and quantitative forms. Further investigation on this issue may help instructional designers and developed of science courses in the decision on various aspects of course design and development.

This paper aims to investigate textual characteristics of customer reviews that motivate companies to respond (sentiment negativity and sentiment deviation) and how aspects of these company responses (response intensity, length and tailoring) affect subsequent customer review quality (comprehensiveness and readability) over time.

Leveraging a large data set from a leading app website (Shopify), the authors combine text mining, natural language processing (NLP) and big data analysis to examine the antecedents and outcomes of online company responses to reviews.

This study finds that companies are more likely to respond to reviews with more negative sentiment and higher sentiment deviation scores. Furthermore, while longer company responses improve review comprehensiveness over time, they do not have a significant influence on review readability; meanwhile, more tailored company responses improve readability but not comprehensiveness over time. In addition, the intensity (volume) of company responses does not affect subsequent review quality in either comprehensiveness or readability.

This paper expands on the understanding of online company responses within the digital marketplace – specifically, apps – and provides a new and broader perspective on the motivations and effects of online company responses to customer reviews. The study also extends beyond the short-term focus of prior works and adds to literature on long-term effects of online company responses to subsequent reviews. The findings provide valuable insights for companies (especially those with apps) to enhance their online communication strategies and customer engagement.

Drawing on the conservation of resources theory, the present study aims to design and explore the influence of abusive supervision and coworker incivility on turnover intention among frontline employees (FLEs). Besides the mediating effects of work stress between abusive supervision and turnover intention, coworker incivility and turnover intention also be explored.

Data from 311 FLEs are collected by a self-administered structured questionnaire and analyzed by confirmatory factor analysis and structural equation model.

The empirical results established that abusive supervision and coworker incivility significantly predicts work stress and work stress significantly predicts turnover intention. Abusive supervision significantly predicts a positive relationship with turnover intention, whereas coworker incivility with turnover intention is vis-à-vis. Besides, abusive supervision and coworker incivility significantly predict turnover intention via work stress. The study further illustrated the control variables, e.g. education, experience, and proactive personality of FLEs.

The study finds abusive supervision and coworker incivility as stressors in the emerging economy for FLEs. However, coworker incivility on turnover intention cannot predict as expected because the roles of the supervisor and coworker are different in this context.

The continuous support of supervisors and coworkers can reduce the stress and consequences of reducing the intention of turnover of FLEs. The concerns can enhance their support by using respect and credit for work, maintaining privacy, providing proper feedback, being sensible to the performance, and entitlement to any achievement. They also suggest ensuring a work environment of privacy, fair treatment, importance to suggestions, and ascertaining punishment for any colleague's mistreatment.

The frontliners always contribute a large pie of output for any organization. Supervisors and coworkers impact the day-to-day life of FLEs.

As a study on FLEs in the context of evolving economy, the investigation fulfills the inconsistencies of the previous result with the mediating role of work stress with a strong theoretical base.

On the basis of person–job fit theory and conservation of resource theory, this study aims to develop and test a model to examine the impact of polychronicity on frontline employees’ job performance in hotel industry and simultaneously, investigate the moderating effects of supervisor, coworker and customer incivility as stressors in the relationship between polychronicity and employees’ job performance.

Data are obtained in North Cyprus from 262 frontline employees working in four- and five-star hotels.

The results suggest that polychronicity refers to employees’ performance. Customer incivility negatively and significantly influences job performance, but coworker and supervisor incivilities do not. Unlike coworker incivility, both customer and supervisor incivilities moderate the relationship between polychronicity and job performance; that is, high customer and/or supervisor incivility weaken the positive relationship between polychronicity and job performance.

Regarding the critical role of polychronic frontline employees, hotel management should recruit the right candidates and endeavor to retain such employees by offering monetary and non-monetary incentives, training and empowering. They may implement a zero-tolerance policy that simultaneously supports both parties (customers and employees).

The association between employee quality (i.e. polychronicity), job performance and incivility is often overlooked in the hospitality research. This study is the first attempt to consider the joint moderating effect of important social stressors (customer, coworker and supervisor incivility) in the hotel industry.

This study aimed to determine the factors affecting consumers’ perceptions and intention to purchase home meal kit services (HMK), a convenient home-cooked meal option, considering the moderating effects of monetary restriction, through the lens of the theory of planned behaviour (TPB).

This cross-sectional study used an online, self-administered survey to collect data from 374 US adults. Results were tested for variable associations via multiple linear regression and moderation analyses.

HMK adoption intention was positively associated with attitude and subjective norms but negatively associated with perceived behavioural control. Consumers’ HMK attitude demonstrated a significant positive relationship with food safety concerns and perceived time constraints. Income and financial constraints were significant moderators of the associations between TPB determinants and HMK intention. The findings emphasised the possibility of using HMK as a foodservice option for time-challenged consumers with food safety concerns.

This study addressed the limited research on HMK, a competitive meal option that foodservice businesses could implement to boost revenue. The study establishes the contribution in understanding the motivators and barriers that potentially affect consumers’ HMK behaviour through the lens of TPB. The results expand the scope of the TPB application in food-related research, providing a deeper understanding of antecedents and other factors on consumers’ HMK behavioural attitudes. Understanding this information will enable practitioners to develop strategies that meet consumers’ concerns when embracing this service to promote HMK.

A zero-day vulnerability is a complimentary ticket to the attackers for gaining entry into the network. Thus, there is necessity to device appropriate threat detection systems and establish an innovative and safe solution that prevents unauthorised intrusions for defending various components of cybersecurity. We present a survey of recent Intrusion Detection Systems (IDS) in detecting zero-day vulnerabilities based on the following dimensions: types of cyber-attacks, datasets used and kinds of network detection systems.

Purpose: The study focuses on presenting an exhaustive review on the effectiveness of the recent IDS with respect to zero-day vulnerabilities.

Methodology: Systematic exploration was done at the IEEE, Elsevier, Springer, RAID, ESCORICS, Google Scholar, and other relevant platforms of studies published in English between 2015 and 2021 using keywords and combinations of relevant terms.

Findings: It is possible to train IDS for zero-day attacks. The existing IDS have strengths that make them capable of effective detection against zero-day attacks. However, they display certain limitations that reduce their credibility. Novel strategies like deep learning, machine learning, fuzzing technique, runtime verification technique, and Hidden Markov Models can be used to design IDS to detect malicious traffic.

Implication: This paper explored and highlighted the advantages and limitations of existing IDS enabling the selection of best possible IDS to protect the system. Moreover, the comparison between signature-based and anomaly-based IDS exemplifies that one viable approach to accurately detect the zero-day vulnerabilities would be the integration of hybrid mechanism.

The purpose of this study is to determine how consumers perceive restaurant service in Bangladesh. The goal of this study is to determine the impact of perceived service quality and price fairness on consumer satisfaction and loyalty toward restaurant services.

The data for this study were collected from 326 respondents who have used restaurant services in Bangladesh. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to evaluate the research data with SmartPLS 3.3.3.

The current study’s findings indicate that perceived service quality and price fairness both have a direct and significant effect on consumer satisfaction. Additionally, the research findings reveal a considerable association between perceived pricing fairness and consumer pleasure and consumer loyalty. Additionally, findings indicate that perceived service quality and price fairness both have a significant indirect effect on customer loyalty via the mediating effect of consumer satisfaction.

The current study demonstrates that perceived price fairness has a substantial effect on restaurant consumers’ satisfaction and loyalty; thus, this evidence can assist restaurant owners and managers in developing and implementing their pricing strategy to retain customers. Additionally, the findings have significant implications for restaurant operators, practitioners and policymakers.

Only a few research have been conducted to determine the effect of service quality and pricing fairness on consumer satisfaction and loyalty when it comes to restaurant services. This research conclusion provides guidance to service providers on how to increase customer satisfaction and loyalty through an emphasis on price fairness and service quality.

Celebrity endorsers are usually considered to bring positive effects to associated nodes, such as brands and corporations. However, limited evidence suggests that brands and corporations are equally responsible for affecting celebrities and their credibility. Drawing on associative network theory, this study explores the effects of brand credibility and corporate credibility on celebrity credibility, both directly and through the mediating and moderating effects of advertising credibility. The research addresses three main issues: (1) whether brand credibility, corporate credibility and advertising credibility have significant effects on celebrity credibility; (2) whether advertising credibility has a significant mediating effect on the effects of brand credibility and corporate credibility on celebrity credibility and (3) whether advertising credibility has a significant moderating effect on the effects of brand credibility and corporate credibility on celebrity credibility.

The study used a quantitative approach involving structural equation modelling. Data were collected from 675 participants from London and focussed on four leading international brands, corporations and celebrity endorsers.

The findings show that brand credibility and advertising credibility have positive direct effects on celebrity credibility; and that advertising credibility mediates the effects of both credibility constructs on celebrity credibility. Furthermore, moderating effects of advertising credibility are also found.

This study will help managers to understand the reverse effects, i.e. the effects of brand credibility and corporate credibility on celebrity credibility. They will be able to understand that a credible brand and corporation like a credible celebrity can also bring significant effects on the associated elements. This will help them to recruit celebrity endorsers who have historically earned their credibility from previous endorsements of credible brands and corporations. Further, these findings will help managers to understand that credibility of the brand and corporation can also affect the credibility of the associated advertising, resulting in having a significant effect on the credibility of the celebrity. This on the consumers’ side will enhance their preferences, attitudes and behaviours, while for the corporation, it will enhance their economic and commercial performance.

This is the first study in the literature, where a conceptual model based on the reverse effects of both credibility constructs on celebrity credibility is examined, directly and based on the moderating and mediating effects of advertising credibility. Hence, the contributions to the literature are threefold: first, the study examines the reverse effect of celebrity endorsement, whereby the credibility of a brand or corporation is transferred to a celebrity endorser; second, the study examines the mediating and moderating effects of advertising credibility on this reverse effect and finally, associative network theory is used to examine the importance of the model.

The paper provides a step-by-step guide in the guise of a roadmap for service improvement initiatives using importance performance map analysis (IPMA).

To empirically illustrate how IPMA can be applied to any service industry, three sectors are considered; sports and fitness (study A), hospitality (study B) and higher education (study C). Following the proper selection of measuring instruments and their evaluation using structural equation modeling-partial least squares (Smart-PLS), IPMA is applied to identify those attributes having strong total effects (high importance) over the targeted construct (satisfaction) but which also have low average latent variable scores (low performance).

For sports and fitness (study A), the physical aspects and programme quality require managerial attention. For the hospitability sector (study B), it is service commitment, interaction quality and internal sense of happiness. Whereas for higher education (study C), it is administrative quality as well as the element of transformative quality, namely the university’s role in adding to its students’ emotional stability, which needs the attention of the top management.

This study provides researchers and practitioners with a roadmap for applying PLS-SEM and IPMA for continuous service quality improvement. The roadmap extends upon Ringle and Sarstedt’s (2016) work. It highlights critical decisions that need to be considered in the pre-analytical stages of the IPMA application, i.e. at the research design phase in selecting the most appropriate service quality measurement model specifications. It not only contributes to the existing body of knowledge by providing empirical evidence to advance theory development in the quality management field but also has implications for the practitioners in any service sector on where to focus their attention for an effective service improvement.
