The Bed and Breakfast (B&B) enterprises generally lack sufficient human resources and time to conduct research on important social media marketing factors for visitors’ satisfaction and visitors’ intentions. Therefore, this study aims to provide crucial social media marketing and factors and service quality elements for improving customer satisfaction and customer loyalty in B&B sectors. This study also provides some recommendations for attracting more visitors and increasing customer satisfaction and customer loyalty through social media.

First, social media marketing factors and service quality elements were identified through the systematic literature review. Then these identified factors and elements were used to design a survey questionnaire for collecting data. The research data included responses of 64 B&B enterprises and 625 customers. The collected data was analyzed by feature selection approaches including Decision Tree algorithm and Information Gain to identify the key factors for improving customer satisfaction and customer loyalty.

The findings of this study determined that featured choice is an important social media marketing factor, and assurance is the common service quality element for both B&B enterprises and their customers in terms of satisfaction and loyalty.

This study adds a value to the growing literature on customer satisfaction and loyalty in B&B sectors by exploring key social media marketing factors and service quality elements. The study reveals several implications for theories and practices. The findings hopefully help B&B enterprises better social media marketing with less workforce and budget.

The current study examines the relation of guanxi human resource management (HRM) practices with subjective evaluations of creative performance by direct supervisors, as well as conceptualizes the employee ambidextrous behavior as a mediator, and social comparison orientation and leader–member exchange (LMX) as moderators for understanding the relation.

Survey data were collected from 211 employee–supervisor dyads in China. Hierarchical regression analyses, Preacher and Hayes’ (2008) indirect effects PROCESS macro, and Preacher et al.'s (2007) moderated mediation analysis approach were conducted to test the hypothesized relationships.

Guanxi HRM practices were negatively associated with employee creative performance, mediated by the employee ambidextrous behavior. The authors also found that social comparison orientation showed a strong moderating effect, such that it amplified the indirect relationship between guanxi HRM practices and employee creative performance via ambidextrous behavior. In contrast, LMX showed a weak moderating effect, such that it attenuated this indirect relationship.

This study provides evidence that the extent to which employee ambidextrous behavior mediates the relationship between guanxi HRM practices and creative performance depends on LMX and social comparison orientation. It represents a promising new direction for the guanxi HRM practices and creative performance literatures.

The current study examines the effects of leader humor on the creativity of employees by focusing on the mediating role of relational energy and the moderating role of traditionality.

This study used three-wave data from 302 employee–supervisor dyads and tested the hypotheses using hierarchical regression and bootstrapping.

The results indicated that leader humor was positively associated with employee creativity, relational energy mediated this influence. Besides, traditionality not only moderated the relationship between leader humor and relational energy but also attenuated the indirect relationship between leader humor and employee creativity through relational energy.

Leadership training programs can be used to assist leaders in improving their humorous skills. In addition, supervisors should implement humorous behaviors according to the different levels of traditionality of employees.

Integrating conservation of resource theory, this study provides solid evidence that the extent to which relational energy mediates the relationship between leader humor and employee creativity depends on traditionality. It provides a new direction for leader humor.

This study supposes to provide new insights into the role of leader behaviors in motivating employees by examining how and when spiritual leadership and contingent reward leadership facilitate employee vigor at work.

Drawing from self-determination theory (SDT), the current study proposes that spiritual leadership intrinsically motivates employees, whereas contingent reward leadership extrinsically motivates employees – both of which subsequently improve employee vigor at work. The theoretical model was tested through a sample of 191 employees collected across three time points in China.

Results revealed that spiritual leadership positively facilitates employee vigor at work through enhancing their work enjoyment, and employees' need for achievement can amplify the effects of spiritual leadership. In addition, employees' performance-reward expectancy transmits the effects of contingent reward leadership on employee vigor at work, and leaders' performance expectations play a key role in strengthening the positive influences of contingent reward leadership.

Based on SDT, this study provides a comprehensive explanation of how and when two patterns of leader behaviors affect employee vigor at work. Therefore, the authors provide significant insights for leadership and work design in human resource management.

The purpose of this paper is to examine the relationship between servant leadership and customer service behaviors by probing the mediating role of promotion focus and the moderating role of internal locus of control.

The authors hypothesized an indirect relationship between servant leadership and customer service behaviors through promotion focus. Also, the authors predicted that the positive relationship between servant leadership and promotion focus would be stronger for employees with low internal locus of control. The authors tested the theoretical model with data gathered across two phases over three months from 280 supervisor-subordinate dyads.

Results indicated that servant leadership was positively related to customer service behaviors via promotion focus. Results also showed that internal locus of control moderated the relationship between servant leadership and promotion focus, such that the relationship was stronger for employees low on internal locus of control. Furthermore, this moderated mediated model was supported. As predicted, the indirect effect was stronger when internal locus of control was low.

This study extends the regulatory focus theory to the service context to investigate how and when servant leadership enhances customer service behaviors. The authors suggested promotion focus as a key mediating mechanism and revealed internal locus of control as a boundary condition for the effectiveness of servant leadership.

This study highlights the importance role of promotion focus in fostering customer service behaviors and provides novel theoretical insight regarding when servant leadership enhances customer service behaviors.

The purpose of this paper is to develop a finite volume approach for the simulation of three-dimensional two-phase (polymer melt and air) flow in plastic injection molding which is capable of robustly handling the mesh non-orthogonality and the discontinuities in fluid properties.

The presented numerical method is based on a cell-centered unstructured finite volume discretization with a volume-of-fluid technique for interface capturing. The over-relaxed approach is adopted to handle the non-orthogonality involved in the discretization of the face normal derivatives to enhance the robustness of the solutions on non-orthogonal meshes. A novel interpolation method for the face pressure is derived to address the numerical stability issues resulting from the density and viscosity discontinuities at the melt–air interface. Various test cases are conducted to evaluate the proposed method.

The presented method was shown to be satisfactorily accurate by comparing simulations with analytical and experimental results. Besides, the effectiveness of the proposed face pressure interpolation method was verified by numerical examples of a two-phase flow problem with various density and viscosity ratios. The proposed method was also successfully applied to the simulation of a practical filling case.

The proposed finite volume approach is more tolerant of non-orthogonal meshes and the discontinuities in fluid properties for two-phase flow simulation; therefore, it is valuable for engineers in engineering computations.

Based on social information processing theory, this paper aims to explore how and when leader self-deprecating humor may spark subordinate learning from failure. The authors cast perspective taking as a novel explanatory mechanism for this indirect effect, and further consider leader–member exchange as a boundary condition of the relationship.

The authors tested the hypotheses by conducting a multiwave and multisource survey of 604 members from 152 teams in a Chinese high-technology company.

Results of multilevel path analyses demonstrate that leader self-deprecating humor positively influences subordinate learning from failure via perspective taking. Further, this mediation effect is stronger at higher levels of leader–member exchange.

This study contributes to the theoretical understanding of the relationship between leader self-deprecating humor and subordinate learning from failure. However, the research design was not longitudinal or experimental, and thus the authors were unable to make strong inferences about absolute causality.

The work yields useful insights for practitioners aiming to encourage subordinates to learn from failure.

This study provides evidence that leader self-deprecating humor can stimulate subordinate learning from failure via perspective taking, and the indirect effect is further strengthened by leader–member exchange. The findings offer new directions for research on leader self-deprecating humor and learning from failure.

The purpose of this paper is to demonstrate a simple fiber sensor for simultaneous measurement of liquid refractive-index (RI) and temperature.

The sensor structure is formed by a long period fiber grating cascaded with a section of thin-core fiber. The long period fiber grating is fabricated on single mode fiber, followed by a section of 20-mm length thin-core fiber which is a modal interferometer.

Cladding mode interference between long period fiber grating and thin-core fiber modal interferometer is weak in the experimental investigation. Both of these two cladding mode type fiber devices are sensitive to surrounding RI and temperature. So the RI and temperature can be measured simultaneously by monitoring the spectral characteristics of the compound sensor. The sensitivity is calibrated and sensor matrix is provided in the experiment.

This proposed fiber sensor is simple, tough, cost-effective and suitable for discriminate the liquid RI and temperature with high sensitivity.

The purpose of this paper is to examine the causal correlation between the work stress of immigration officers (IOs) and the cross-level effect of social support.

A multilevel model was used to analyze the quantitative data obtained from 231 IOs in Taiwan, who served as the research objects.

From the results of this study, it was found that a positive significant relationship existed between role conflict and work stress, as well as between work stress and job burnout. Also, cross-level context and moderating effect for the relationship between social support and work stress, as well as between social support, work stress and job burnout were obtained.

This study only considered IOs in airports and ports. Therefore, it is necessary to determine if other topics of organizational behavior, such as the leadership of supervisors, organizational climate and work values of IOs, have a positive moderating effect. In this regard, it is recommended that a longitudinal study should be conducted in the future.

The phosphorus and zinc contained in zinc dialkyl dithiophosphate (ZDDP) caused severe environment pollution and catalyst poison. Thus, the phosphorus-free additive, such as borate esters, has become one of studying hot topics in the area of oil additive. However, the stability of hydrolysis greatly limited the use of borate esters. The purpose of this paper is to improve the stability of hydrolysis by synthesizing a new kind of N-containing heterocyclic borate ester (MTTDB) as a lubricant additive.

The tribological properties of novel borate ester (MTTDB) as an additive in the base oil were studied by a four-ball machine. The element composition and chemical state of the tribofilm were investigated by scanning electron microscopy, energy dispersive spectrometer and X-ray photoelectron spectroscopy.

The results showed that the base oil lubricated by MTTDB exhibited high hydrolytic stability, good anti-wear property and excellent extreme pressure performance. When 2.5 per cent MTTDB was added into the 100N base oil, the smallest wear scar diameter (0.46 mm) was obtained. Furthermore, the decomposed borate ester, organic sulfide adsorbed on the worn surface was detected, and S element reacted with the steel surface and generated FeSO4, both of which contributed to the formation of the tribofilm.

Based on N-containing heterocyclic compounds, for instance, thiadiazole derivatives, introducing nitrogen and sulfur elements into borate ester, a new kind of N-containing heterocyclic borate ester (MTTDB) exhibited excellent property in hydrolysis stability, friction-reducing, anti-wear and extreme pressure. This synthesized method would be helpful for the borate ester used as additive in engine oil, gear oil and other industrial lubricants.
