Selective laser sintering (SLS) is an essential technology in the field of additive manufacturing. However, SLS technology is limited by the traditional point-laser sintering method and has reached the bottleneck of efficiency improvement. This study aims to develop an image-shaped laser sintering (ISLS) system based on a digital micromirror device (DMD) to address this problem. The ISLS system uses an image-shaped laser light source with a size of 16 mm × 25.6 mm instead of the traditional SLS point-laser light source.

The ISLS system achieves large-area image-shaped sintering of polymer powder materials by moving the laser light source continuously in the x-direction and updating the sintering pattern synchronously, as well as by overlapping the splicing of adjacent sintering areas in the y-direction. A low-cost composite powder suitable for the ISLS system was prepared using polyether sulfone (PES), pinewood and carbon black (CB) powders as raw materials. Large-sized samples were fabricated using composite powder, and the microstructure, dimensional accuracy, geometric deviation, density, mechanical properties and feasible feature sizes were evaluated.

The experimental results demonstrate that the ISLS system is feasible and can print large-sized parts with good dimensional accuracy, acceptable geometric deviations, specific small-scale features and certain density and mechanical properties.

This study has achieved the transition from traditional point sintering mode to image-shaped surface sintering mode. It has provided a new approach to enhance the system performance of traditional SLS.

Urging people to avoid stockpiling was a common declaration made by governments during the COVID-19 pandemic outbreak, yet empty supermarket shelves and supply shortages of basic products were observed worldwide. This study aims to (a) identify the factors that activate consumer personal norms towards socially responsible behaviours, specifically resisting stockpiling, and (b) examine how fear moderates the link between personal norms and consumer engagement in stockpiling during public crises.

The study recruited a sample of US consumers who were responsible for household grocery shopping during the COVID-19 pandemic. A total of 593 individuals participated in the study, and the collected data were analysed using structural equation modelling.

The results show that awareness of the negative consequences of stockpiling and a sense of personal responsibility for those consequences activate personal norms towards responsible shopping during public crises. However, perceived fear has the opposite effect, encouraging stockpiling. In addition, fear weakens the negative relationship between personal norms and stockpiling.

This study extends the norm activation model and indicates that personal norms may not always promote responsible behaviours when fear is high. It is unique in that it sheds light on non-mainstream responsible consumption behaviours (e.g. resisting stockpiling), and the interaction between consumption and social responsibility.

The purpose of this study is to investigate how the digital competence of academicians influences students’ engagement in learning activities in the face of the pandemic outbreak. In addition to this, the paper investigates how digital competence influences each dimension of student engagement (cognitive, affective and behavioural).

A cross-sectional, quantitative and explanatory research design was used to conduct the study. Data were gathered with an adopted questionnaire administered to a randomly selected sample of 500 university faculty members who were not digitally literate prior to the outbreak of the pandemic. Apart from the goodness of data tests, inferential statistics were applied to test hypotheses.

Results indicate a significant influence of teachers’ digital competence on student engagement and the pandemic outbreak positively moderates the relationship. Digital competence equally influences all three dimensions of student engagement.

The outbreak of COVID-19 made the adoption of digital life more compulsive and the nations with already available digital infrastructure and digital competence effectively minimized the adverse effect of social distancing as a result of the pandemic outbreak. Findings emphasize practitioners to focus on the digital capacity building of academicians and the provision of digital infrastructure to facilitate student engagement.

Society is transforming into a hi-tech lifestyle and technological advancement is penetrating almost every sphere of life at an unprecedented pace. From the digitalization of day-to-day affairs to e-governance, the adoption of technology is becoming a new normal. The outbreak of the pandemic overtook academic institutions equally. So, the social distancing compelled academicians and other stakeholders of universities to switchover from in-campus classes to online classes. The findings enrich the existing body of literature by explaining how digital competence has a determining role in ensuring student engagement amid the COVID-19 outbreak.

This research is a seminal work, as it tests the influence of digital competence on student engagement with the moderating role of the pandemic outbreak. To the best of the author’s knowledge, existing literature does not present this kind of research.

Based on the stimulus-organism-response (S-O-R) model, this study examines how safety measures, related assistance and tangible benefits affect consumers' emotional and cognitive states, leading to behavioural responses in an uncertain store environment.

The proposed model was tested with the survey data collected from grocery shoppers in Japan and Croatia (n = 314 in each country) and analysed using structural equation modelling.

Safety measures and related assistance decreased perceived threat in Croatia, enhanced arousal in both countries and caused fear in Japan. Tangible benefits reduced fear in Japan and increased arousal in Croatia. In a crisis, perceived threats push unplanned buying and motivate consumers to protect themselves. Arousal drives unplanned buying but diverts consumers from health-focussed behaviour. Loyalty can be gained if fear is controlled.

To retain consumers, retailers should secure a safe shopping environment that reduces fear and provides enough benefits to outweigh the threat.

Using the S-O-R framework, this study enriches the literature on consumer behaviour in a pandemic by contributing new insights into (1) the impact of safety measures and tangible benefits as stimuli, (2) the organismic response through affective and cognitive states, (3) health-focussed behaviour as a novel outcome and (4) comparing the effects in the two countries.

Tourists’ irresponsible behaviours (e.g. damaging flowers, writing and painting on the walls and throwing waste material in the water and around the sea site) damage the coastal environment. The irresponsible behaviour of tourists has raised concerns about the sustainability of the coastal tourism environment. The purpose of this study is to identify and explain the behavioural patterns of tourists that can influence the environmentally responsible behaviours (ERBs) of tourists, particularly in the context of coastal tourism. The study aims to provide a theoretical and practical explanation of destination image and perceived destination value (PDV) in shaping ERB with the mediating role of destination social responsibility (DSR) among tourists at the coastal touring destination.

The study used a quantitative research design and data were gathered from the five beaches in Karachi. Structured equation model was used to analyse the direct and mediating effect while stepwise regression was used to analyse the moderating effect of DSR. The results of the direct effect showed that cognitive image has a significant effect on the affective image, while the insignificant effect on conative image and ERB. While the affective image has a significant effect on conative and ERB, and finally, results showed a significant effect of conative image on ERB. Results of the study revealed that PDV significantly mediated the relationship between cognitive, affective and conative destination image and ERB. Finally, the study’s results revealed that DSR has significantly moderated the relationship between affective, conative destination image, PDV and ERB.

The results are divided into three categories, direct effect, mediating effect and moderating effect. The results of the direct effect showed that cognitive image has a significant effect on the affective image, while the insignificant effect on conative image and ERB. While affective image has a significant effect on conative and ERB, and finally, results showed a significant effect of conative image on ERB. It is found in the results that PDV significantly mediated the relationship between cognitive, affective and conative destination image and ERB. Finally, the study’s results revealed that DSR has significantly moderated the relationship between affective, conative destination image, PDV and ERB.

First, data has been collected from a single geographic area of Pakistan. Therefore, cross-country data are required to compare the ERB of tourists. Second, only local respondents are considered in the study; future studies may include foreign tourists as well. Finally, data has been collected during one month in summer, which may have measured the experience of only summer. The respondent may have different perceived values and destination images during winter. The future study may split data collection into summer and winter to cover diverse perceptions of tourists.

It is almost impossible for coastal destinations to achieve a competitive advantage without attaining sustainable coastal environments. Clean and green beaches and responsible behaviour towards marine mammals can only be achieved through tourists’ ERB. This study has major contributions towards society by reserving the natural environment of coastal areas.

This research will significantly contribute to the existing literature by extending the ERB knowledge through the theoretical lens of cognitive-affective-conative models and social expectancy theory. Moreover, PDV as a mediator and DSR as a moderator will enhance the understanding of ERB and extend the existing literature. Further research has provided a strong understanding of how cognitive, effective and conative image helps in influencing the ERB of tourists. Moreover, research will benefit destination managers and policymakers to enhance the image and perceived value of touring destinations. Finally, this study is a unique attempt to present a comprehensive model which could be applicable to diverse situations and areas.

This study aims to investigate city branding as a post-pandemic COVID-19 outcome factor on brand satisfaction, brand experience, perceived risk and revisit intention. In addition, this research contributes to the discussion of post-COVID-19 city branding that needs to be considered in the development of future tourism marketing.

A quantitative approach was used with PLS-SEM statistical analysis and a 263-tourist sample. The study was conducted on tourists from Malang Regency in Indonesia by distributing questionnaires modified from previous studies in a similar context.

The results of this study found that there were significant influences of city brand personality on brand experience, brand satisfaction, brand experience on perceived risk, brand satisfaction on revisit intention and perceived risk on revisit intention. This study also presents the mediating role.

The study was only conducted on a small regency in Indonesia, and therefore the results cannot be generalized for other cities over the world.

The proposed study model suggests that stakeholders must seek to socialize services to potential tourists, so that tourists can understand the description of tourism activities that can be enjoyed during the COVID-19 pandemic and the way they travel in the future.

Understanding the determinant factors of city branding post-COVID-19 was valuable for developing marketing strategies to cope with intense competition among the city.

This study emphasizes the determinants of COVID-19 perceived risk and revisit intentions as explained in the tourism marketing literature by considering the role of brand satisfaction, brand experience and city brand personality which significantly contribute to build the city competitiveness. Therefore, various creative strategies should be implemented to promote the city as well as escalate tourist visits without ignoring the pandemic’s risks.
