Abstract

Purpose

Focusing on firm-initiated brand communities, the purpose of this paper is to systematically examine the influence of brand community rejection on consumer evaluations and document the underlying mechanism involved.

Design/methodology/approach

Four empirical studies were conducted to test the proposed hypotheses. Using a similar 2 × 2 study design, different subject samples and different product categories, Studies 1-3 investigated whether a brand community rejection strategy impacted strong brands differently than weak brands. Furthermore, Study 3 measured reactance as a moderator to explore the underlying process of the impact of a brand community rejection strategy on brand evaluations for different types of brands (i.e. strong vs weak). Study 4 used a 2 × 2 × 2 between-subjects design to examine whether justification would eliminate the negative impact of brand community rejection on subsequent brand evaluations for a weak brand.

Findings

Across the four studies, the findings consistently suggest that rejection from firm-initiated brand communities harms weak brands but not strong brands. In addition, by incorporating psychological reactance as a moderator of this effect, the authors uncover the process underlying the interaction between brand community rejection and brand strength. Furthermore, the paper examines the reasons that justify rejection to find a solution that eliminates the negative impact of brand community rejection on brand evaluations for weak brands.

Originality/value

To the best of the authors’ knowledge, this research provides the first investigation of the effects of a brand community rejection strategy for different brands. The findings could advance the social exclusion literature and shed new light on brand community research.

Abstract

Purpose

Under the influence of loading, manufacturing, installation and other factors, the axis of sleeve bearing and journal will not be aligned, which will have a great impact on running stability and life of bearing. The existence of oil groove can effectively improve the life of sleeve bearing and working efficiency. The lubrication performance of two and three grooves sleeve bearing considering journal misalignment is analyzed.

Design/methodology/approach

To solve the difference of discontinuous position of oil film thickness, it is necessary to use the flow balance relationship in the finite control space, and oil film thickness equation of multi-groove sleeve bearing considering journal misalignment is gained.

Findings

The friction and bearing capacity of journal bearing with oil groove increase with the increase of journal inclination angle. At the same journal inclination angle, the bearing capacity of two-axial groove journal bearing is larger than that of three-axial groove journal bearing, but the friction of two-axial groove journal bearing shows the trend of the first bigger and then smaller than that of three-axial groove journal bearing.

Originality/value

The research has great significance to optimize bearing lubrication performance and increase bearing working life.

Abstract

Purpose

This paper aims to reveal the cavitation characteristics of three oil wedges sleeve bearing and set the theoretical and experimental basis for defining the oil film boundary condition.

Design/methodology/approach

Computational fluid dynamics model of three oil wedges sleeve bearings based on the Navier–Stokes equation is set using Fluent considering turbulent situation and two-phase flow theory. The cavitation characteristics of bearing is investigated by taking pictures of experiment.

Findings

The rupture region of oil film and the contours of air volume fraction increase distinctly with the increase of rotating speed and the decrease of input pressure. The critical rotating speed of cavitation occurrence and oil film pressure increases with the increase of input pressure. The change trend of experiment cavitation with the rotating speed and input pressure is consistent with theoretical cavitation in general.

Abstract

Purpose

Researchers have not reached an agreement on which biomimetic shape has the best lubrication performance. This paper aims to study the influence of microtexture size, shape and direction on bearing capacity, end leakage, friction coefficient and wear of oil film.

Design/methodology/approach

Different oil film thickness equations considering the microtexture of bearing surface are gained. The two-dimensional finite difference equation and the calculation equation of wear are established.

Findings

The theoretical research shows that the wear value and the wear ratio when long side is perpendicular to the axial direction of the bearing are generally lower than when the long axis is parallel to the axial direction of bearing. The theoretical and experimental results show that the appropriate microtexture shape, such as circular dimple, crescent-shaped dimple, triangular dimple and fish-shaped dimple can improve effectively the lubrication performance of journal bearing and reduce the friction coefficient.

Originality/value

The research has great significance to reduce friction and improve the wear resistance of equipment.

Abstract

Purpose

Based on the survey data of 1,152 households in three provinces of Shaanxi, Gansu and Ningxia on the Loess Plateau, this paper aims to empirically analyze the impact of aging and off-farm employment on farmers’ adoption behavior of soil and water conservation technology. This paper analyzes the moderating effect of social network and the mediating effect of technological cognition in this impact relationship.

Design/methodology/approach

Based on the above analysis, the second part of this paper is based on relevant theories and constructs a theoretical model of the relationship of aging, off-farm employment, social network, technology cognition and farmers’ adoption behavior of soil and water conservation technology. The third part introduces research methods, variable selection and descriptive statistics analysis of variables. The fourth part, based on the data of Shaanxi, Gansu and Ningxia provinces in the Loess Plateau in 2016, empirically analyzes the impact of aging, off-farm employment and social network on the farmers’ adoption behavior of soil and water conservation technology. This paper further examines the moderating effect of social network and the mediating effect of technology cognition in this influence relationship. Finally, based on the findings of the empirical study, this paper puts forward countermeasures and suggestions.

Findings

First, aging and off-farm employment have a significant negative impact on farmers’ adoption behavior of soil and water conservation technology, while social network has a significant positive effect. Second, social network has alleviated the effect of aging and off-farm employment on restraining farmers’ adoption behavior of soil and water conservation technology. Third, aging and off-farm employment have restrained farmers’ cognition of soil and water conservation technology. Social network has promoted farmers’ cognition of soil and water conservation technology. Social network plays a moderating role in the impact of aging and off-farm employment on farmers’ cognition of soil and water conservation technology. Technology cognition plays a mediating role in the impact of social network on farmers’ adoption behavior of soil and water conservation technology.

Originality/value

This paper integrates the aging, off-farm employment and social network into the same analytical framework and reveals their impact on farmers’ adoption behavior of soil and water conservation technology and its action mechanism, which enriches the impact of human capital and social network on farmers’ adoption behavior of soil and water conservation technology. Then taking the social network as a moderator variable, the paper verifies its moderating effect on the relationship of aging, off-farm employment and farmers’ adoption behavior of soil and water conservation technology. Farmers’ technology cognition should be included in the analysis framework to examine the impact of aging, off-farm employment and social network on farmers’ cognition of soil and water conservation technology. Taking the technology cognition as a mediator variable, the paper verifies its mediating effect on the relationship of aging, off-farm employment and farmers’ adoption behavior of soil and water conservation technology.

Abstract

Purpose

The purpose of this study is to evaluate the effectiveness of one online PD in PBL. Researchers want to investigate if a five-day international online PBL training will prepare teachers to implement PBL in their classrooms. Secondly, the researchers aim to determine if the training provides teachers with sufficient knowledge and support to ensure successful PBL implementation.

Design/methodology/approach

Participants were given a 5-day (20 h) online PBL training created by one of the researchers with three frontline teachers. Seven trainers are divided into four groups for four groups of participants. Group A included Grade 1 and Grade 2 teachers, Group B included Grade 3 and Grade 4 teachers, Group C included Grade 5 and Grade 6 teachers, and Group D consisted of Grades 7 through 9 teachers. All the participants were given exactly the same surveys at the beginning and the end of the training.

Findings

Consistent with previous studies comparing in person and virtue PD programs, this five-day interactive PD program was effective in increasing teachers' knowledge of and ability to plan and implement PBL projects. Specifically, results showed that teachers' knowledge level of PBL shifted from a shallow understanding of what the name implies to a deeper, more comprehensive, and more concrete understanding of PBL essential concepts, its pedagogical values, specific process involved in a PBL project. In addition, the PD program increased teachers' comfort level and ability of planning and implementing PBL projects across grade levels and subject areas.

Originality/value

This research study supported the previous study results that virtual PD programs can be as effective as in person programs. Further, this is the study discovered the effectiveness of PBL training between the US and China through online format, which has not been conducted literately before. The positive results will be used to promote the online collaboration internationally in the future.

Abstract

Purpose

Based on consumers’ geographic real-time locations, firms can utilize mobile targeting promotion (MTP) to target consumers through some applications embedded in mobile device. This paper aims to focus on two competing firms about how to make MTP strategies under asymmetric mobile accessibilities, i.e. the proportions of consumers who can be targeted by firms through apps are different.

Design/methodology/approach

This paper develops a game model for two competing firms. Aiming to maximizing profit, firms should consider how to utilize MTP strategies to trade off the benefit (expand market share) and the cost (intensive price competition).

Findings

The optimal MTP strategies and equilibrium prices have been presented under different scenarios. This paper verifies that asymmetry can make the firm with high mobile accessibility obtain extra profits. Furthermore, when unit targeting cost is relatively low, profit of the firm with low mobile accessibility increases first and decreases later with respect to its mobile accessibility.

Practical implications

Competing firms’ optimal MTP strategies and equilibrium prices are determined not only by unit targeting cost but also by consumers’ mobile accessibilities to firms. Firms have strong incentive to enlarge the mobile accessibility to procure more profit in monopoly context, but, under competing context, a higher mobile accessibility may not mean better for firm.

Originality/value

This is one of the few papers which study mobile targeting based on game theory considering unit targeting cost and asymmetric mobile accessibility simultaneously.
