Meal ordering apps (MOAs) have transformed the customers' dining habits, particularly during mobility restrictions of the COVID-19 pandemic. Under the theoretical cover of the extended stimulus–organism–response (SOR) model, this paper attempts to explore the critical antecedents and outcomes of customer MOA engagement which predict the continuous purchase intentions using these apps. A multigroup analysis is conducted to investigate the difference between the hypothesized relationships between the Chinese and Indonesian consumers.

A mixed-method approach, including a systematic literature review, an open-ended essay (qualitative) with 139 MOA users and an online survey (quantitative) with 1,207 MOA users in total, was used for hypotheses testing.

The structural equation model results revealed that customer MOA experience factors such as mobile online reviews (MR), food quality (FQ), restaurant reputation (RR), service quality and system quality (SyQ) are the absolute positive factors that influence customer MOA cognitive, affective and behavioral engagement, which in turn affect continuous purchase intentions. The multigroup analysis results reveal that Chinese customers prioritized MR and FQ for customer MOA engagement (cognitive, affective and behavioral). Comparatively, Indonesian customers placed most importance on RR and SyQ.

Considering a market-specific setting and based on the extended SOR framework, this study is one of the first to take a comprehensive look at the critical antecedents and outcome of multidimensional customer MOA engagement in the developing countries’ (China and Indonesia) online to offline meal delivery context. Further, this study investigates the customer continuous purchase intentions as an outcome of MOA engagement during the COVID-19 pandemic. The findings also reveal the differences in consumer behavior across the two developing but culturally diverse countries samples during the pandemic.

This study examines how service feedback and physician popularity affect physician demand in the context of virtual healthcare environment. Based on the signaling theory, the critical factor of environment uncertainty (i.e. disease risk) and its impact on physician demand is also investigated. Further, the research on the endogeneity of online reviews in healthcare is also examined in the current study.

A secondary data econometric analysis using 3-wave data sets of 823 physicians obtained from two PRWs (Healthgrades and Vitals) was conducted. The analysis was run using the difference-in-difference method to consider physician and website-specific effects.

The study's findings indicate that physician popularity has a stronger positive effect on physician demand compared with service feedback. Improving popularity leads to a relative increase in the number of appointments, which in turn enhance physician demand. Further, the impact of physician popularity on physician demand is positively mitigated by the disease risk.

The authors' research contributes to a better understanding of the signaling transmission mechanism in the online healthcare environment. Further, the findings provide practical implications for key stakeholders into how an efficient feedback and popularity mechanism can be built to enhance physician service outcomes in order to maximize the financial efficiency of physicians.

Using the lens of conservation of resources (COR) theory, the purpose of this paper is to explore the effect of humble leadership on project success by integrating the mediating role of goal clarity. The authors also argue that organizational culture moderates these direct and indirect relationships through goal clarity.

Time-lagged data were collected from 329 employees in the civil construction sector of Pakistan.

The results indicate that humble leadership enhances project success through mediating and moderating mechanisms.

The present research ends with an argument, managerial consequences, limits and guidance for future research.

The results influence a project-based organization on the selection and promotion of humility among project managers.

This research answers the following research question, which has been ignored in the literature: What are the suggested mechanisms for humble leadership in promoting project success?

This paper aims to examine the impact of humble leadership on project success. The mediating effects of psychological empowerment and innovative work behavior on the relationship between humble leadership and project success are tested.

Data were collected from 337 individuals employed in the civil construction sector of Pakistan.

The results showed that humble leadership is positively related to project success. Furthermore, psychological empowerment and innovative work behavior partially mediate the relationship between humble leadership and project success.

Drawing on conservation of resource theory, this study found that how humble leadership is important for project success and thus extends the utility of the concept of humble leadership to the project literature.

With a foundation in the conservation of resource theory, this paper aims to examine the validity of a conceptual model that explains the mechanism connecting perceived threat of terrorism to production deviance. The link between perceived threat of terrorism and production deviance was examined via emotional exhaustion. Notably, the study evaluated whether the relationship between perceived threat of terrorism and production deviance is mediated by emotional exhaustion and moderated by levels of emotional intelligence.

The study is cross-sectional in nature and data were collected from 432 pharmaceutical sales representatives who operate outdoors in the high-risk region. Two-step approach consisting confirmatory factor analysis and structural equation modeling was used for analysis. To examine conditional direct and indirect effects, the authors used model 8 in PROCESS.

Results were consistent with prediction made from the conceptual model in that emotional exhaustion partially mediated the relationship between perceived threat of terrorism and production deviance. This was particularly the case when emotional intelligence was low, but not when high. Likewise, perceived threat of terrorism exerted a direct effect on production deviance when emotional intelligence was low, but not when high.

The study is the first to examine the relationship between perceived threat of terrorism and production deviance. Moreover, no study to date has examined the mediating role of emotional exhaustion between perceived threat of terrorism and production deviance. Finally, up till now, it is unknown that emotional intelligence moderates the relationship of perceived threat of terrorism with emotional exhaustion and production deviance.

Social media has broadened the scope of luxury brand marketing and has emerged as a salient tool for Internet marketing campaigns in the post-pandemic world. Under the theoretical lens of the SOR model, this study aims to explore the nexus between brand social media marketing (BSMM) activities and online consumer brand engagement (CBE) via mediating consumers' emotions in the modest luxury fashion branding post-pandemic context.

This study conducted a post-pandemic survey in five major metropolitan cities in Pakistan with a total of 584 eligible young consumers who follow the fan pages of fashion brands. Structural equation modeling was used to test hypotheses.

The findings reveal that BSMM activities have a significant influence on three emotion states (pleasure, arousal and dominance); however, only pleasure and arousal significantly drive CBE (i.e. affective engagement and activation). Moreover, the results show that pleasure and arousal partially mediate the relationships between BSMM activities and affective and activation dimensions of CBE, while dominance fully mediates the relationship between BSMM activities and cognitive engagement. Interestingly, only affective engagement was shown to be the most potent component of CBE in fostering positive emotions toward luxury fashion brands.

This study contributes to the literature on social media marketing and consumer brand engagement by revealing valuable insights into post-pandemic luxury fashion branding that could assist academicians and marketing practitioners of non-Western markets.

The purpose of this paper is to develop a model to examine how different technological and cognitive cues related to mobile food ordering applications (MFOAs) impact diners' intentions to use MFOAs continuously. The moderating role of national household demographics was also assessed in the online-to-offline (O2O) food delivery services (FDS) context.

Drawing insights from the uses and gratification (U&G) theory, an online sample survey of 968 valid respondents who had ordered or purchased food through delivery apps during the COVID-19 outbreak in China was used for the analysis. The proposed model was empirically tested using structural equation modeling.

The results revealed that cues in MFOAs (i.e. ease of use, convenience, price saving orientation, the listing of various food choices, exploring restaurant patterns, and compatibility) directly influenced diners' e-satisfaction and that intention to use continuously is triggered by e-satisfaction during the COVID-19 crisis. Moreover, this study found that collectivist household diners emphasized ease of use, convenience, and compatibility. Comparatively, individualistic household diners placed more importance upon price saving orientation and listing of various food choices during the pandemic.

The authors offer a new insight into customers' dining choices by extending the scope of O2O services in the food industry. The findings contribute to understanding diners' purchase decision-making processes regarding MFOAs' O2O-FDS during the COVID-19 crisis. The multi-group comparison via national household demographics also provides a new perspective regarding different dining preferences toward O2O-FDS.

The latest mobile technology may shape consumers' motivations by allowing them to order a variety of foods using smartphone apps. Following the stimulus–organism–response (SOR) framework and using a mixed methods approach, this study investigates the impacts of different components of mobile dining on customers' perceived value, which leads to actual purchase intentions. Furthermore, this study examines the moderating effect of the restaurant type.

Data were collected via an online questionnaire survey from 351 individuals in the city of Jakarta (Indonesia) who actually used mobile apps to order food online. Data analysis was carried out using structural equation modeling.

The findings reveal that source credibility, review valence, the navigation system, food quality and service quality significantly impact customers' perceived value. Customers' perceived value, in turn, positively affects their purchase intentions. The findings also reveal that the impacts of review valence, the navigation system, food quality and service quality on customers' perceived value depend on the different levels of restaurants.

This study is among the first in the mobile commerce research that studies the impacts of mobile electronic word-of-mouth (eWOM), system quality and overall restaurant image on dining choices by considering actual mobile shoppers. Second, this study extends the SOR model to examine the impact of the mobile environment-based characteristics on the perceived value that leads to purchase intentions. Third, the current study examines whether the relationships that are discussed early on differ based on the restaurant type. The findings of this study could help practitioners achieve a deeper understanding of diners' behaviors due to the perceived benefits of mobile dining.

This paper aims to present a technique that has been developed to study the wear in the camshaft and tappet. The engine manufacturers use the most suitable materials, lubrication additives and surface coatings to minimize friction in all the components of the engine. Reduced friction results in less wear of critical engine components. The researchers are constantly trying to find an improved lubrication formula which reduces the wear and friction coefficient at a considerably low price. In this regard, the cam follower interface is of much importance because most of the wear occurs in this interface.

The tappets and the cam lobes are analyzed to determine wear. A two-dimensional optical surface profilometer is used to measure the tappet wear, and a high-resolution linear variable differential transformer is used for the measurement of cam lobes. Tests are conducted on Mercedes Benz engine OM 646 under constant camshaft speed, constant inlet lubricant temperature and constant lubricant pressure to study the oil rheology on cam tappet wear.

The results show that the wear occurs on the cam tappet interface, which is almost a linear phenomenon, and it increases with use.

Customized jigs were made to measure wear of camshaft and tappet.

Based on trait activation theory, the purpose of the present study is to explore the relationship between the antecedents and outcomes of informal learning with the moderating effect of supervisor feedback environment (SFE) in small- and medium-sized enterprises (SMEs).

Data (n = 388) were gathered from middle managers of Pakistan’s SME sector by following the purposive sampling technique. The proposed model was examined by means of structural equation modeling analysis with AMOS 24.

The study results delineate that middle managers with high-level self-efficacy and motivation to learn more actively participate in informal learning activities. The study also found that the SFE is a strong contextual moderator between the nexus of personal factors and informal learning. In addition, informal learning also has significant and positive effect on work engagement.

Human resource practitioners and organizational leaders of small businesses can use informal learning to improve employees’ skills and knowledge with less cost. For instance, management should use different strategies to enhance the effectiveness of informal learning by providing SFE.

There are numerous recent calls for research to ascertain the interaction of individual, contextual factors and outcomes of informal learning. The study addresses these voids by empirically examining antecedents and outcomes of informal learning simultaneously through the person–situation interaction perspective. It demonstrates that informal learning at the workplace becomes more effective in SFE.
