The purpose of this paper is to focus on investigating the impact of crowd participation on degree of project success, which is defined as the total amount of funds a project can obtain after it reaches its initial funding goal threshold.

Drawing on the theory of crowd capital, this study develops six hypotheses about the impact of crowd capability of a fundraiser (i.e. project updates, goal setting, reward levels and social media usage) and crowd participation (i.e. namely, funds pledge and on-site communication) on degree of project success. The hypotheses are tested using data sets of successful projects collected from two popular crowdfunding websites.

This study finds that funds pledge has an inverse U-shaped relationship with degree of project success. Project updates, reward levels and on-site communication positively influence degree of project success, while funding goal negatively affects degree of project success.

This study contributes to prior literature by investigating the degree of project success determinants using the perspectives of both fundraisers and crowds, which provides a more comprehensive understanding of what makes a crowdfunded project a success.

The empirical results of this study provide fundraisers with guidelines about how to access more funds after achieving the initial funding goals.

This work is one of the first to investigate the degree of project success and its determinants from the perspectives of both fundraisers and crowds.

Although microblogs have become an important information source, the credibility of their postings is still a critical concern due to the open and unregulated nature. To understand the antecedents of microblog information credibility, the purpose of this paper is to investigate the dual-role of cognitive heuristics (i.e. the additivity and bias roles) and the effect of gender differences.

This study collected data via an online field survey of active microblog users, and a total of 204 valid responses was received.

This study demonstrates the dual-role of source credibility and vividness, the additivity role of microblog platform credibility, and the bias role of social endorsement. Furthermore, this study also found out gender difference that the additivity role of cognitive heuristics was stronger for men while bias role was stronger for women.

This research enriches the microblog literature by examining the cognitive heuristic determinants as key predictors of microblog information credibility, and contributes to the information credibility literature by identifying and analyzing the dual-role effect of cognitive heuristics and corresponding gender differences.

This study can help organizations better manage their reputation, especially during the reputation crises, and also serves as a reminder to microblog platform operators of the importance of their microblog platform credibility.

This study investigates the dual-role effect of cognitive heuristics (i.e. the additivity role and bias role) and corresponding gender differences that are less touched on before, and thus provides a more nuanced understanding of the more complex effects of cognitive heuristics.

The purpose of this paper is to investigate the unsteady aerodynamic characteristics in the deflection process of a morphing wing with flexible trailing edge, which is based on time-accurate solutions. The dynamic effect of deflection process on the aerodynamics of morphing wing was studied.

The computational fluid dynamic method and dynamic mesh combined with user-defined functions were used to simulate the continuous morphing of the flexible trailing edge. The steady aerodynamic characteristics of the morphing deflection and the conventional deflection were studied first. Then, the unsteady aerodynamic characteristics of the morphing wing were investigated as the trailing edge deflects at different rates.

The numerical results show that the transient lift coefficient in the deflection process is higher than that of the static case one in large angle of attack. The larger the deflection frequency is, the higher the transient lift coefficient will become. However, the situations are contrary in a small angle of attack. The periodic morphing of the trailing edge with small amplitude and high frequency can increase the lift coefficient after the stall angle.

The investigation can afford accurate aerodynamic information for the design of aircraft with the morphing wing technology, which has significant advantages in aerodynamic efficiency and control performance.

The dynamic effects of the deflection process of the morphing trailing edge on aerodynamics were studied. Furthermore, time-accurate solutions can fully explore the unsteady aerodynamics and pressure distribution of the morphing wing.

The purpose of this study is to propose a fractal model of thermal contact conductance (TCC) of two spherical joint surfaces, considering friction coefficient based on the three-dimensional fractal theory.

The effects of friction coefficient, fractal parameters, radius of curvature and contact type on TCC were analyzed using numerical simulation.

The results indicate that the TCC decreases with the increase of friction coefficient and fractal roughness and increases with the increase of fractal dimension and radius of curvature; the contact type of two spherical joint surfaces has an important influence on the TCC, and the TCC of external contact is smaller than that of internal contact under the same contact load.

A fractal model of TCC of two spherical joint surfaces considering friction coefficient is proposed in this paper. Achievements of this work provide some theoretical basis for the research of TCC of bearings and other curved surfaces.

Based on the self-concept perspective, the purpose of this paper is to explore the process of working mothers who conduct job crafting to build new role identities and self-efficacy, which ultimately affects work-to-family enrichment. The paper further explores the moderating role of inclusive leadership.

The authors collected data at two time points. The sample for the study consisted of 216 professional working mothers in China who returned to work after the birth of their first child.

Results show that working mothers' job crafting had a positive effect on work-to-family enrichment. In addition, working mothers' role identity and role self-efficacy played mediating roles between the links. Finally, inclusive leadership moderates the indirect effect of task crafting and relational crafting on work-to-family enrichment through role identity and role self-efficacy. The positive indirect relationships are stronger in high levels of inclusive leadership.

The employers should provide opportunities, support, and freedom for working mothers to craft their jobs according to their individual demands for better self and home outcomes.

This study focuses on the job crafting of working mothers. The authors extend the consequences of job crafting to the nonwork domain. In addition, this study uncovers the influence of job crafting from the perspective of self-concept (i.e. role identity and role self-efficacy). Furthermore, the authors demonstrate the moderating role played by inclusive leadership in this process.

This study aims to investigate the effect of brand personality and consumer ethnocentrism on perceived quality and purchase intentions in China's sportswear market.

In order to examine and compare the effect of brand personality and consumer ethnocentrism on the evaluation of product quality and purchase intention toward domestic and foreign brands, COB (the country with which the brand or firm is associated) and COM (the country in which final production takes place) cues were used in this study. Chinese college students represented the sample of 385 respondents. Structural equation modeling was used to investigate the causal relationships among brand personality, consumer ethnocentrism, perceived quality, and purchase intention.

Results revealed that brand personality has a significant effect on Chinese consumers' product quality perceptions and purchase intentions toward both domestic and foreign brands. Furthermore, it is found that Chinese consumers' ethnocentric tendencies have no significant impact on their intentions to buy either domestic or foreign sportswear brands. However, ethnocentric Chinese consumers do positively evaluate the quality of domestic brands when domestic brands are also made domestically and negatively evaluate the quality of foreign brands when foreign brands are also manufactured non-domestically.

The study contributes theoretically and empirically to research on the effects of brand image and consumer ethnocentrism in emerging markets. The findings from this study will help domestic and international marketers have a better understanding of the role of brand personality and consumer ethnocentric tendencies in influencing young Chinese consumers' product evaluation and purchase intentions. In addition, few studies have simultaneously examined the effects of brand image and consumer ethnocentrism (moderated by COO) on consumers' product evaluations and purchase intentions, which provided new research and managerial implications.

Aiming at the problem that quadruped crawling robot is easy to collide and overturn when facing obstacles and bulges in the process of complex slope movement, this paper aims to propose an obstacle avoidance gait planning of quadruped crawling robot based on slope terrain recognition.

First, considering the problem of low uniformity of feature points in terrain recognition images under complex slopes, which leads to too long feature point extraction time, an improved ORB (Oriented FAST and Rotated BRIEF) feature point extraction method is proposed; second, when the robot avoids obstacles or climbs over bumps, aiming at the problem that the robustness of a single step cannot satisfy the above two motions at the same time, the crawling gait is planned according to the complex slope terrain, and a robot obstacle avoidance gait planning based on the artificial potential field method is proposed. Finally, the slope walking experiment is carried out in the Robot Operating System.

The proposed method provides a solution for the efficient walking of robot under slope. The experimental results show that the extraction time of the improved ORB extraction algorithm is 12.61% less than the original ORB extraction algorithm. The vibration amplitude of the robot’s centroid motion curve is significantly reduced, and the contact force is reduced by 7.76%. The time it takes for the foot contact force to stabilize has been shortened by 0.25 s. This fact is verified by simulation and test.

The method proposed in this paper uses the improved feature point recognition algorithm and obstacle avoidance gait planning to realize the efficient walking of quadruped crawling robot on the slope. The walking stability of quadruped crawling robot is tested by prototype.
