The outbreak of the COVID-19 pandemic led to the rise of online learning in Hong Kong. Online learning was identified as the only solution to meet students’ learning needs in the higher education sector during this chaotic period. This research aims to explore students’ perceptions of online teaching and learning from home under a health emergency via a comparison of undergraduate and postgraduate students’ experiences.

A total of 174 postgraduate students and 286 undergraduate students in various universities and colleges in Hong Kong were surveyed in this study.

The results show that postgraduate students generally gave more positive feedback on individual and environmental prerequisites, alongside pedagogical and institutional support, and were more motivated in online classes as compared to undergraduate students. Undergraduate students considered the shift to online education in light of the COVID-19 pandemic to be timely and rated their level of discipline with respect to online learning higher than did postgraduate students.

This study enables educators to better understand the first-hand experiences of students across different levels of study in Hong Kong, as well as to examine the possibility of establishing online education as a more prevalent mode of study in the future. The COVID-19 pandemic has educated us on the significance of being well-prepared to ensure quality education continues when emergencies and disturbances arise.

As technology increasingly integrates into the restaurant industry, avatar servers present a promising avenue for promoting healthier dining habits. Grounded in the halo effect theory and social comparison theory, this study aims to delve into the influence of avatars' appearance, humor and persuasion on healthier choices and customer satisfaction.

This paper comprises three experimental studies. Study 1 manipulates avatar appearance (supermodel-looking vs normal-looking) to examine its effects on perceived attractiveness, warmth and relatability. These factors influence customer satisfaction and healthy food choices through the psychological mechanisms of social comparison and aspirational appeal. Studies 2 and 3 further refine this theoretical model by assessing the interplay of appearance with humor (presence vs absence) and persuasion (health-oriented vs beauty-oriented), respectively.

Results suggest that avatars resembling supermodels evoke stronger aspirational appeal and positive social comparison due to their attractiveness, thus bolstering healthier choices and customer satisfaction. Moreover, humor moderates the relationship between appearance and attractiveness, while persuasion moderates the effects of appearance on social comparison and aspirational appeal.

This research bridges the halo effect theory and social comparison theory, offering insights enriching the academic discourse on technology’s role in hospitality.

The findings provide actionable insights for managers, tech developers and health advocates.

Despite its significance, avatar design research in the hospitality sector has been overlooked. This study addresses this gap, offering a guideline for crafting attractive and persuasive avatars.

Historically, most CEOs were promoted from within the organization. The internal candidates offer continuity, are well known to the Board, and have deep institutional knowledge. However, if the Board is seeking changes to the firm’s strategy, operations, or culture, they turn to outside candidates with proven track records. Shareholders react positively to the announcement of an external successor but the longer-term evidence on the performance front is mixed. Most empirical studies have tended to focus on a narrow aspect of the hiring choice, whereas we undertake a more holistic examination involving various elements.

We consider the salience of the CEO hiring choice from several perspectives: educational background, gender, compensation, and firm performance. We use a propensity score matching approach to ensure comparability between internally promoted and externally hired CEOs. The observed covariates for the matching algorithm include firm size, CEO tenure, and industry sector.

We find that external CEOs are significantly more likely to have received their undergraduate degree from an elite institution, majored in a STEM discipline, and earned an MBA credential. They earn higher total compensation (with a higher proportion of equity-linked performance pay) but do not outperform in terms of the ROA or Tobin’s Q metrics. Gender does not appear to play a distinguishing role in the internal versus external hiring choice. We also do not detect significant differences in firm performance outcomes associated with educational pedigree, a STEM education, or an MBA credential, whether the CEO is internally promoted or hired externally.

Our paper contributes by providing novel evidence on the impact of educational background on external CEO hiring decisions. Our findings carry implications for testing hypotheses stemming from signaling theory and exploring the significant role of social networks associated with elite educational institutions. Also, the finding that externally appointed CEOs do not outperform their internally promoted counterparts may be noteworthy for corporate boards' hiring committees, especially when reviewing candidates who are edge cases.

To ensure the stability of the flying wing layout unmanned aerial vehicle (UAV) during flight, this paper uses the radial basis function neural network model to analyse the stability of the aforementioned aircraft.

This paper uses a linear sliding mode control algorithm to analyse the stability of the UAV's attitude in a level flight state. In addition, a wind-resistant control algorithm based on the estimation of wind disturbance with a radial basis function neural network is proposed. Through the modelling of the flying wing layout UAV, the stability characteristics of a sample UAV are analysed based on the simulation data. The stability characteristics of the sample UAV are analysed based on the simulation data.

The simulation results indicate that the UAV with a flying wing layout has a short fuselage, no tail with a horizontal stabilising surface and the aerodynamic focus of the fuselage and the centre of gravity is nearby, which is indicative of longitudinal static instability. In addition, the absence of a drogue tail and the reliance on ailerons and a swept-back angle for stability result in a lack of stability in the transverse direction, whereas the presence of stability in the transverse direction is observed.

The analysis of the stability characteristics of the sample aircraft provides the foundation for the subsequent establishment of the control model for the flying wing layout UAV.

This study aims to address the critical subject of building capacity for the circular economy in the global south. It complements the literature by providing information on the role of higher education institutions in developing skills for the circular plastic economy.

This study used a mixed method approach drawing on reflective analysis on qualitative data from 5 focus groups and 12 semi-structured interviews, and structural equation modelling of quantitative data from 151 students across 4 Nigerian Universities.

The results indicate that Nigerian university students are more likely to participate in the circular plastic economy through a high prominence of soft power features such as increased awareness, inspiration, idea generation, encouragement and capacity building.

The main limitation of this study is with the sample. A larger data set, including other tertiary institutions such as private universities, polytechnics and schools of vocational studies, would strengthen the results.

The study underlines the importance of targeted policy interventions and pedagogic innovations to drive awareness and knowledge building among Nigeria’s youth population.

This study makes a novel contribution by using empirical evidence to determine the predictors of student participation in the circular plastic economy. This understanding is important for the development and implementation of appropriate policies that promote participation in the circular plastic economy. Furthermore, given the typical youthful age bracket of university students, any plans to achieve a systemic shift in the plastic value chain must involve the young generation.

The purpose of this paper is to investigate the moderating role of cultural factors (concern for face and stability of attribution) in the relationships among service recovery quality, postrecovery satisfaction and repurchase intention. Based on the politeness theory, this paper proposes a theoretical model for understanding how concern for face and stability of attribution may affect collectivists’ consumption behavior.

Data were collected in a field survey of 600 Hong Kong consumers who had experienced a telecommunications service failure. Partial least squares structural equation modeling (PLS-SEM) was used to test the theoretical hypotheses.

A cultural factor of concern for face is found to negatively moderate the relationship between service recovery quality and postrecovery satisfaction. Face also positively influences the relationship between postrecovery satisfaction and repurchase intention. Another cultural factor, stability of attribution, is found to negatively moderate the relationship between service recovery quality and postrecovery satisfaction and to negatively moderate the relationship between postrecovery satisfaction and repurchase intention.

This study contributes to the understanding of the relevance of concern for face and stability of attribution in collectivists’ consumption behavior. The findings have significant implications for managers in a position to exploit the cultural value mechanisms of collectivist consumers.

To the best of the authors’ knowledge, this has been the first research to examine the impact of concern for face and stability of attribution among service recovery quality, postrecovery satisfaction and repurchase intention.

While the tourism–growth nexus is one of the better researched themes in both tourism and economics literature, there is limited evidence on how institutional quality affects this link, especially in the context of the developing world. To address this gap, this study aims to investigate the tourism-led growth hypothesis (TLGH) through the lens of institutional quality, drawing on evidence from African economies.

This study adopts a longitudinal design, involving panel data on 43 countries over an 18-year period, and the data were analyzed using the difference generalized method of moments model.

Results indicated that international tourism earnings contributed to economic growth in the selected economies. However, institutional quality negatively moderated the tourism–growth relationship on the continent, particularly in low-income economies, while reinforcing this link in middle-income countries.

This study provides new insights into how the TLGH varies across different levels of institutional quality and development.

本研究创新性地研究了旅游主导增长假说 (TLGH) 在不同制度质量和发展水平下的不同表现。

Aunque el nexo entre turismo y crecimiento es uno de los temas mejor investigados tanto en la literatura turística como en la económica, existen pocas pruebas sobre cómo afecta la calidad institucional a este vínculo, especialmente en el contexto del mundo en desarrollo. Para abordar esta laguna, el presente estudio investiga la hipótesis del crecimiento impulsado por el turismo a través de la perspectiva de la calidad institucional, basándose en evidencias de las economías Africanas.

El estudio adopta un diseño longitudinal, con datos de panel sobre 43 países a lo largo de un periodo de 18 años, y los datos se analizaron utilizando el modelo de diferencias del Método generalizado de momentos.

Los resultados indicaron que los ingresos del turismo internacional contribuyeron al crecimiento económico de las economías seleccionadas. Sin embargo, la calidad institucional moderó negativamente la relación turismo-crecimiento en el continente, particularmente en las economías de renta baja, mientras que reforzó este vínculo en los países de renta media.

El estudio brinda nuevos conocimientos sobre cómo la hipótesis de crecimiento impulsado por el turismo (TLGH) varía en diferentes niveles de calidad institucional y desarrollo.

This research paper aims to explore the concerns and determinants of travelers’ behavior toward ChatGPT in the hospitality and tourism context. It also examines the weight of risk factors versus that of motivation and innovation characteristics influencing travelers’ approach behaviors toward ChatGPT.

A cumulative prospect theory was used to determine travelers’ responses to ChatGPT. This study, using a fuzzy-set qualitative approach, explored risk, motivation and innovation factors as determinants of approach behaviors for ChatGPT.

Findings revealed that risk, motivation and innovation factors were the key triggers of approach behaviors for ChatGPT. An intricate combination effect of the perceived risk, motivation and innovation characteristics was found, and the necessary predictors were determined.

The findings of this study will expand our current knowledge and offer practical insights for the development of ChatGPT in the hospitality and tourism sector.

This study makes a significant contribution to the existing literature by providing a nuanced understanding of the intricate interplay between the various factors that shape customer behavior in the context of technology adoption in hospitality and tourism studies.

Diversity policies have become widespread in modern organizations. Such policies often have the goal of improving the workplace experiences of marginalized groups, and understanding dominant group reactions to such policies is vital to their effectiveness. This paper investigated the dominant group (i.e. White individuals) response to diversity policies, specifically how White individuals’ modern racism beliefs influence their organizational citizenship behavior (OCB) intentions when exposed to a diversity policy.

Using experimental methodology and a combination of social exchange theory and literature on modern racism, the two studies explore how exposure to a diversity (versus neutral) policy influences White individuals’ OCB intentions in two different settings (lab and field).

The results of these studies make clear that certain people respond negatively to diversity policies. In Study 1, White participants with relatively high modern racism beliefs showed lower OCB intentions directed at their organization when exposed to a diversity versus neutral policy. No differences emerged for White participants with relatively low modern racism beliefs. In Study 2, the results were replicated using a field sample of working adults in which they indicated their likelihood of OCB toward their employing organization.

The findings suggest that diversity policies can have unintended, adverse consequences for organizations, but are dependent upon employees’ modern racism beliefs. The results of the two studies provide a richer understanding of dominant group reactions to diversity policies by examining a downstream consequence of great organizational importance, i.e. OCB.

The energy efficiency of buildings has been emphasized along with the continual development in the building and construction sector that consumes a significant amount of energy. To this end, the purpose of this research paper is to forecast energy consumption to improve energy resource planning and management.

This study proposes the application of the convolutional neural network (CNN) for estimating the electricity consumption in the Grey Nuns building in Canada. The performance of the proposed model is compared against that of long short-term memory (LSTM) and multilayer perceptron (MLP) neural networks. The models are trained and tested using monthly electricity consumption records (i.e. from May 2009 to December 2021) available from Concordia’s facility department. Statistical measures (e.g. determination coefficient [R²], root mean squared error [RMSE], mean absolute error [MAE] and mean absolute percentage error [MAPE]) are used to evaluate the outcomes of models.

The results reveal that the CNN model outperforms the other model predictions for 6 and 12 months ahead. It enhances the performance metrics reported by the LSTM and MLP models concerning the R², RMSE, MAE and MAPE by more than 4%, 6%, 42% and 46%, respectively. Therefore, the proposed model uses the available data to predict the electricity consumption for 6 and 12 months ahead. In June and December 2022, the overall electricity consumption is estimated to be 195,312 kWh and 254,737 kWh, respectively.

This study discusses the development of an effective time-series model that can forecast future electricity consumption in a Canadian heritage building. Deep learning techniques are being used for the first time to anticipate the electricity consumption of the Grey Nuns building in Canada. Additionally, it evaluates the effectiveness of deep learning and machine learning methods for predicting electricity consumption using established performance indicators. Recognizing electricity consumption in buildings is beneficial for utility providers, facility managers and end users by improving energy and environmental efficiency.
