In this work, a series of BaTiO3-based ceramic materials, Ba(Al0.5Nb0.5)xTi1-xO3 (x = 0, 0.04, 0.06, 0.08), were synthesized using a standard solid-state reaction technique. X-ray diffraction profiles indicated that the Al+Nb co-doping into BaTiO3 does not change the crystal structure significantly with a doping concentration up to 8 %. The doping ions exist in Al3+ and Nb5+ chemical states, as revealed by X-ray photoelectron spectroscopy. The frequencydependent complex dielectric properties and electric modulus were studied in the temperature range of 100~380 K. A colossal dielectric permittivity (>1.5 × 104) and low dielectric loss (<0.01) were demonstrated at the optimal dopant concentration x = 0.04. The observed dielectric behavior of Ba(Al0.5Nb0.5)xTi1-xO3 ceramics can be attributed to the Universal Dielectric Response. The complex electric modulus spectra indicated the grains exhibited a significant decrease in capacitance and permittivity with increasing co-doping concentration. Our results provide insight into the roles of donor and acceptor co-doping on the properties of BaTiO3-based ceramics, which is important for dielectric and energy storage applications.

Artificial photosynthesis harnesses clean and sustainable solar power to catalyze the conversion of CO2 and H2O molecules into valuable chemicals and O2. This sustainable approach combines energy conversion with environmental pollution control. Non-oxide photocatalysts with broad visible-light absorption and suitable band structures, hold immense potential for CO2 conversion. Nevertheless, they still face numerous challenges in practical applications, particularly in CO2 conversion with H2O. Surface modification and functionalization play the significant role in improving the activity of non-oxide photocatalysts. Multifarious strategies, such as cocatalyst loading, surface regulation, doping engineering, and heterostructure construction, have been explored to optimize light harvesting, bandgap driving force, electron–hole pairs separation/transfer, CO2 adsorption, activation, and catalysis processes. This review summarizes recent progress in surface modification strategies for non-oxide photocatalysts and discusses their enhancement mechanisms for efficient CO2 conversion. These insights are expected to guide the design of high-performance non-oxide photocatalyst systems.

Graphite felt is a felt-like porous material made of high-temperature carbonized polymers. It is widely used in electrode materials because of its good temperature resistance, corrosion resistance, large surface area and excellent electrical conductivity. In this paper, the surface functional group modification is of graphite felt electrodes (mainly nitrogen doping modification, nitrogen–sulfur or nitrogen–boron co-doping modification) and surface catalytic modification (metal/ion surface modification and metal oxide surface modification as Main). There are two main methods and research progresses to improve the performance of graphite felt electrodes, and the comprehensive performance of surface functional group-modified graphite felt electrodes and surface catalytically modified graphite felt electrodes are compared respectively. The results show that both surface functional group modification and surface catalytic modification can improve the comprehensive performance of graphite felt electrodes. In this paper, the future development direction of graphite felt activation modification is also prospected.

Background: Virtual reality (VR) programs based on motion capture camera are the most convenient and cost-effective approaches for remote rehabilitation. Assessment of physical function is critical for providing optimal VR rehabilitation training; however, direct muscle strength measurement using camera-based kinematic data is impracticable. Therefore, it is necessary to develop a method to indirectly estimate the muscle strength of users from the value obtained using a motion capture camera. Objects: The purpose of this study was to determine whether the pedaling speed converted using the VR engine from the captured foot position data in the VR environment can be used as an indirect way to evaluate knee muscle strength, and to investigate the validity and reliability of a camera-based VR program. Methods: Thirty healthy adults were included in this study. Each subject performed a 15-second maximum pedaling test in the VR and built-in speedometer modes. In the VR speedometer mode, a motion capture camera was used to detect the position of the ankle joints and automatically calculate the pedaling speed. An isokinetic dynamometer was used to assess the isometric and isokinetic peak torques of knee flexion and extension. Results: The pedaling speeds in VR and built-in speedometer modes revealed a significantly high positive correlation (r = 0.922). In addition, the intra-rater reliability of the pedaling speed in the VR speedometer mode was good (ICC [intraclass correlation coefficient] = 0.685). The results of the Pearson correlation analysis revealed a significant moderate positive correlation between the pedaling speed of the VR speedometer and the peak torque of knee isokinetic flexion (r = 0.639) and extension (r = 0.598). Conclusion: This study suggests the potential benefits of measuring the maximum pedaling speed using 3D depth camera in a VR environment as an indirect assessment of muscle strength. However, technological improvements must be followed to obtain more accurate estimation of muscle strength from the VR cycling test.

E-commerce has been rapidly growing in China which has quickly become the largest e-commerce market in the world. However, this has also led to an increasing number of e-commerce disputes. In practice, such disputes are resolved by online dispute resolution. As the results of online dispute resolution are not legally binding, however, China’s online arbitration procedure has been criticized especially regarding the conflicts between party autonomy and institutional autonomy. China’s judicial reviews would claim that such awards cannot be enforced. Therefore, there is a call to make online arbitral awards enforceable and to expand the application of online arbitration to more e-commerce disputes in China. This paper examines how to best analyse and address such conflicts. We explain the importance of arbitral institutions’ autonomy in terms of ensuring access to justice as well as the importance of limiting party autonomy in certain circumstances due to the rise in online disputes.

In view of the activated carbon pore-forming mechanism, the fractal hypothesis of pore interior growth was proposed by optimizing the structure of Sierpinski sponge. Based on the hypothesis and the definition of fractal dimension, the function relationship between the reaction degree, reaction step length, specific surface area and pore volume was deduced, and the pore fractal growth model of activated carbon activation process was established. Semi-coke, apple charcoal and lychee charcoal were used to prepare activated carbon. The pore size distributions of the activated carbons are in accordance with the fractal growth hypothesis. Further, the reaction degree and reaction step length can be determined by the experimental data of pore and surface structure, which verified the feasibility of the pore fractal growth model.

Bi2MoO6 (BMO) via the structure-directing role of CO(NH2)2 is successfully prepared via a facile solvothermal route. The structure, morphology, and photocatalytic performance of the nanoflake BMO are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), fluorescence spectrum analysis (PL), UV-vis spectroscopy (UVvis) and electrochemical test. SEM images show that the size of nanoflake BMO is about 50 ~ 200 nm. PL and electrochemical analysis show that the nanoflake BMO has a lower recombination rate of photogenerated carriers than particle BMO. The photocatalytic degradation of tetracycline hydrochloride (TC) by nanoflake BMO under visible light is investigated. The results show that the nanoflake BMO-3 has the highest degradation efficiency under visible light, and the degradation efficiency reached 75 % within 120 min, attributed to the unique hierarchical structure, efficient carrier separation and sufficient free radicals to generate active center synergies. The photocatalytic reaction mechanism of TC degradation on the nanoflake BMO is proposed.

The purpose of this paper is to investigate factors driving parasocial relationships and their effect on brand equity. A conceptual model including the following variables is proposed: opinion leader attributes, parasocial relationship, brand equity and the moderating effect of endorser-brand congruency. The proposed research model is analyzed using a survey of 301 Chinese consumers. Structural equation modelling is employed to examine the hypothesized relationships among all variables. The findings show that the opinion leader attributes of expertise and exploration positively affect the parasocial relationship between consumers and the endorser, and the parasocial relationship and brand equity are positively associated. Furthermore, endorser-brand congruency acts as a moderator on the relationship between opinion leader attributes and the parasocial relationship. The implications, limitations, and discussions are provided.

Because of their attractive and colorful flowers, many species from the genus Aster serve as garden plants. Chrysanthemum owes its popularity to its ornamental and medicinal herb value. It can be used as a cut flower, potted plant, vegetable, and herbal tea. Plant breeders have attempted to identify the available species and produce new cultivars to improve the quality of chrysanthemum for commercial purposes. The use of cytogenetic studies has paved the way for identifying compatibility, ancestry, and other useful information for this undertaking. Thus, an investigation was conducted into the chromosome numbers of 23 wild Asteraceae species in Republic of Korea to determine their genetic characteristics and variations. The somatic chromosome spread has been used for chromosome counting. The results revealed that Asteraceae species have a chromosome range from 18 (diploid) to 54 (hexaploid). These findings provide primary and important information on the chromosome numbers in chrysanthemum plants that can be used to select the right variety for cultivation.

This research combines the liquid carbon precursor infiltration process for carbon/carbon composites with the fabrication procedure for organic, carbon-matrix friction materials in automotive. In the densification process, different liquid carbon precursors and numbers of densification cycle are adopted to investigate the influence on physical and mechanical properties, microstructure and tribological behavior. Experimental results indicate that the infiltration of liquid carbon precursors could improve the physical, mechanical properties and tribological performances of organic friction materials. The open porosity decreases with the number of densification cycle. Both bulk density and hardness increase with the number of densification cycle. The resin-based specimens show higher hardness and lower open porosity than those of the pitch-based specimens after each densification cycle. The tribological measurement of specimens with different carbon precursors shows that the pitch-based specimen shows lower and more stable friction coefficients and exhibits lower weight losses in comparison with other carbon precursors. Morphological observations show that a large area of smooth lubricative film was easily presented on the worn surfaces of the pitch-based specimens, whereas it was seldom observed on the worn surfaces of the preform specimen and resin-based specimens.

E-WOM is described as all informal communications directed at consumers through Internet-based technology related to the usage or characteristics of particular goods and services, or their sellers (Litvin, Goldsmith and Pan, 2008). In contrast with conventional WOM, e-WOM has unique characteristics. For instance, it often occurs in strangers or fellow consumers, and can be and can be anonymous (Goldsmith & Horowitz 2006; Sen & Lerman 2007). In this regard, people feel free to express opinions without identity disclosure (Goldsmith & Horowitz 2006). INTRODUCTION In a word dominated by social media, the diffusion of e-WOM is undoubtedly speeding up. Plus the international trade prevailing, people can experience products from all over the world at home, and they typically collect both positive and negative e-WOM for domestic and foreign brands with the aim of comprehensively evaluating the brands and their products. It is worth mentioning that in reality consumers often adheres to consumer ethnocentrism (CE) to counter the significant effects of imports on domestic economies and defend against foreign products in local markets. So far, there has been relatively little research on the effect of e-WOM on CE. In our study, we employ social media to discover the impacts of e-WOM on CE with respect to domestic and foreign smart phone brands from the Chinese e-WOM receiver’s perspective. Simultaneously, we test consumer pride and prejudice toward mature industries in the home country. Drawing on survey data from 302 consumers, our study reveals several significant findings. First, positive e-WOM regarding local brands may enhance CE, whereas positive e-WOM regarding foreign brands may reduce CE. Second, Negative e-WOM may break the advantage of CE for domestic brand, which result in the dominance of foreign brand. Third, positive e-WOM may enhance brand equity for both domestic and foreign brands. By contrast, negative e-WOM has no significant influence on Chinese consumers’ attitude toward brand equity. Finally, CE has positive influence on brand equity for domestic brand but not effect on foreign brand. To our best of knowledge, our paper is the first to study the effect of e-WOM on CE, which enriches the relevant theory with regard to CE.

Over the past decade, the field of sport exercise in China gets increasingly popular, resulting in a nationwide exercise fashion (Schulenkorf, Sherry, & Rowe, 2016; Yu, Li, Liu, & Su, 2015). With this new emerging shift, this study tested the proposed structural model, and specifically tested the mediating effects of dimensions of sport team attachment between runners’ team satisfaction and their runner team building behaviors (Morhart, Herzog, & Tomczak, 2009). With a sample size of 301, three dimensions of team attachment, team identity, social bonding, and team expectation were found to be significant influencing runners’ in-role team building behavior and participation in the development of this runner team. Other important findings and implications were further discussed.

Introduction Customer co-creation – customers‘ active participation and interaction with the company during their consumption processes, has gained increasing attention in tourism industry (Bertella, 2014; Chathoth et al., 2016; Campos, 2015). For example, Finnair and Helsinki airport invited passengers to workshop for co-developing new service concepts to improve passenger experience (Loukas, 2013). Despite of the increasing enthusiasm at the firm‘s side, customers do not necessarily share the mindset and feel ready for cocreation. The success of value co-creation greatly depends on continuous collaboration between customers and companies (Chathoth et al., 2013), making knowledge regarding customers‘ engagement in value co-creation essential. However, insufficient research attention has been devoted to theorize and empirically investigate the drivers of cocreation behavior in tourism (Grissemann & Stokburger-Sauer, 2012). To address this research gap, we draw on the organizational socialization theory (Van Maanen & Schein, 1979) to propose and empirically test customer education as driving factor for tourists‘ co-creation behavior during their tours. Additionally, we propose customer readiness as a mechanism mediating the effect of customer education on value co-creation behavior, while such effect should depend on tourists‘ involvement with tourism. Background and hypotheses development Organizational socialization refers to the process by which a newcomer gradually absorbs values, abilities, expected behaviors, and necessary social knowledge for assuming an organizational role and for participating as an organizational member (Louis, 1980, p. 229–230). Similar to the organizational socialization perspective, customer socialization characterizes how customers develop skills, knowledge, and attitude relevant to the marketplace (Ward, 1975), which offers a lens to explain how service providers can assist customers and behave as effective co-creators in the service system (Claycomb, Lengnick-Hall, and Inks, 2001). Büttgen et al (2012) demonstrated that customer socialization by training tactic has more important influence on consistent beliefs of service quality than prior reinforcement experiences, which engenders co-production motivation, in turn, leading to coproduction behavior as distal outcome of the socialization tactic. Previous studies suggest favorable customer outcomes to derive from the provision of customer education (Damali et al., 2016). Thus, this study proposed customer education as a socializing tactic, which is mediated by customer readiness for co-creation, to determine tourists co-creation behavior. The concept of co-creation has gained increasing attention in tourism literature, which is often described as the tourist‘s active participation, engagement and interaction during the consumption experience (e.g., Bertella, 2014; So et al., 2014). As Prahalad and Ramaswamy (2004, p. 8) stated, cocreation is ―the joint creation of value by the company and the customer, allowing the customer to co-construct the service experience to suit her context‖. Indeed, creating a favorable, memorable experience involves not only the service providers but also the tourism customers because customers are always the value co-creator (Vargo and Lusch, 2004). Challagalla and colleagues (2009) posit that firms can reach out to contact the customers to provide service after a sale is complete, rather than respond upon the customer‘s requests. In specific, Challagalla and et al. (2009) suggest the proactive service initiatives to consist of three dimensions, namely proactive prevention, proactive education, and proactive feedback seeking. In this study, the three key forms of proactive post-sales services proposed by Challagalla et al. (2009) provides a foundation that helps us to conceive customer co-creation behavior and define the dimensions underlying customer co-creation behavior of tourism services. Customer education, according to Meer (1984), involves learning activities that are organized and sustained by a firm to impart attitudes, knowledge or skills to customers or potential customers. Meanwhile, customer co-creation readiness (CCR) as a customer‘s condition or state in which he/she feels prepared to collaborate with service provider in value co-creation behavior, indicated by role clarity, ability and motivation to co-create (Meuter et al., 2005). Proper socialization process helps customers understand the product or service process as well as their role in performing service tasks, which not only could prevent customer‘s disruptive behaviors during the service process but also facilitate service flow and productivity (Rollag, 2012). Taken together, we propose the following hypotheses: H1: customer education will have a positive effect on customer co-creation behavior H2: Customer co-creation readiness will mediate the positive effect of customer education on customer co-creation behavior. Further, we postulate that tourist‘s product involvement is a boundary condition that constrains the positive effect of customer socialization. Socialization process does not always have much weight on tourists because the influence of socialization on each individual depends on tourists‘ individual characteristics (Van Maanen & Schein, 1979). Some tourists are highly interested in traveling whereas some consider traveling as a dessert in their meal. In line of this sense, we suggest the following hypothesis: H3: Product involvement will negatively moderate the mediation effect of customer co-creation readiness on co-creation behavior. Methodology The survey was posted on several well-known travel forums and referral networks. After eliminating invalid surveys, the authors obtain 300 valid questionnaires. Table 1 presents the sample characteristics. Customer education are measured by four items adapted from Bell and Eisingerich (2007). Product involvement depicts a customer‘s inherent needs, values, and interest towards tourism and is measured by ten items from Zaichkowsky (1985, 1994). Customer co-creation readiness is measured as a reflective first-order and reflective second-order construct by three dimensions: role clarity, ability, and motivation with 12 items adapted by Dellande et al. (2004) and Meuter et al. (2005). Customer co-creation behavior is measured as a reflective second order and reflective first order construct constituted by three dimensions of co-creation behavior with 12 items developed based on the review of concerns in the pre-site, on-site and post-site from several famous travel agencies. Results Measurement validation of constructs from construct reliability, convergent validity to discriminant validity were examined; and the results are provided in the table 2, indicating measurement validation requirements are satisfactory. Then, hypotheses testing was performed. In each analysis, we control variables, including customer gender, previous transaction experience with the travel agency (EP), and social desirability (SD), which are expected to have potential influence on co-creation behavior. H1 predicts a positive relationship between customer education and value co-creation. In support of H1, the analysis shows that customer education positively relates to co-creation of customers (β = 0.272, p = 0.043, R2adjusted= 0.292). Gender (β =-0.170, p<0.001) and SD (β =0.141, p=0.011) are negatively and positively related to customer co-creation behavior respectively. To test the mediating effect of customer readiness on the relationship between customer education and customer co-creation behavior, we used the PROCESS Macro (model 4) developed by Hayes‘s (2013) and estimated the effects with a bootstrap sample of 5000 cases. The indirect effect test indicates that customer education had a significantly positive effect on customer co-creation via the mediation of customer readiness for co-creation (0.312; 95% bootstrap CI [0.157, 0.517]) because the confidence interval did not include zero. The results support H2. Gender also has a significant effect on customer co-creation (β =-0.189, p <0.05). H3 postulated that product involvement will moderate the mediation effect of customer readiness. We used the PROCESS macro model 8 established by Hayes (2013) to test the moderated mediation. The conditional indirect effect test shows that customer readiness significantly mediates the influence of customer education on customer co-creation behavior, regardless of the level of product involvement (zero was not included in the confidence intervals). Nonetheless, customer education on customer co-creation behavior via customer readiness is significant and stronger in low level of product involvement (0.281; 95% bootstrap CI [0.186, 0.398]) but weaker in high level of product involvement (0.128; 95% bootstrap CI [0.029, 0.256]). Therefore, H3 is supported. Among the controlled variables, gender is the only significant predictor of customer co-creation behavior (β =-0.158, p<0.05). In a summary of dominant results of control variables, gender is significant in all three of the tested hypotheses; particularly, female shows a higher level of co-creation behavior than male. Conclusion we introduced organizational socialization theory to the literature on co-creation of tourism context and explored the effect of firms‘ education effort to socialize customers in co-creation activities. We found customer education as a socialization tactic and then conducting an empirical study by collecting data from several travel agencies to investigate the effect of firms‘ socialization tactic on customer co-creation. The results suggest that customer education could promote customer co-creation through customer readiness as a mediator. We also investigated whether the effect of socialization tactic differs on the different levels of product involvement. The results show that customers with high involvement were less influenced by customer education than those with low involvement.

Subsurface cavities in the asphalt pavement which can cause road depression and cave-in accidents influence on the safety of pedestrians and vehicle drivers in the urban area. The existence of subsurface cavity can increase the tensile strain at the bottom of asphalt layer which is an indicator of fatigue cracking potential, and leads to the weakening of the pavement structural capacity. In this study, the finite element (FE) analysis was conducted to examine the relationship between the critical pavement responses and influencing factors, such as cavity depth and size, asphalt layer thickness, and asphalt concrete modulus. The surface deflections and tensile strains calculated from the ABAQUS FE program were compared to those from ILLIPAVE. It is found from this comparison that there are a good relationship between two analysis results. A three dimensional finite element model which is essential to simulate the hexahedral cavity were used to generate the synthetic database of critical pavement responses. To validate the developed model, the deflection data obtained from field Falling Weight Deflectometer (FWD) testing in four different locations were compared to FE deflections. It is found that the center deflections obtained from the FWD testing and FE analysis are similar to each other with an error values of 2.7, 4.4, 5.5, and 11.9 % respectively. The FE model developed in this study seems to be acceptable in simulating actual field cavity condition. On the basis of the data in the database, various analyses were conducted to estimate the effect of influencing factors on the critical pavement responses. It was found that the tensile strain at the bottom of asphalt layer is affected by all the factors but the most affected by the cavity depth and asphalt concrete modulus. Further studies are recommended to properly account for the effect of cavity’s geometry to pavement response.

An electroless deposition method was used to modify the surface properties of rice husk ceramic particles (RHC) by depositing nano-nickel on the surface of the RHC (Ni-RHC). The dry tribological performances of aluminum matrix composite adobes containing different contents of RHC and Ni-RHC particles have been investigated using a micro-tribometer. Results showed that the Ni–RHC particles substantially improved both the friction and wear properties of the Ni-RHC/aluminum matrix adobes. The optimal concentration was determined to be 15 wt% for both the RHC and Ni–RHC particles. The improvements in the tribological properties of aluminum adobes including the Ni-RHC were ascribed to frictioninduced peeling off of Ni coating and formation of protection layer on the wear zone, both of which led to low friction and wear volume.

The purpose of this study was to measure the mean peak mobilization forces to the lumbar spine 1-3 with grade III and grade IV of posteroanterior (PA) mobilization. Twenty subjects with no history of Lumbar back pain (LBP) (10 female, 10 male) with a mean age of 24.1 years (SD = 6.0) were recruited for the study and PA mobilization were performed in each spine and the therapist took approximately 2.5s to complete mobilization. In the results, applied grade IV force showed no different according to each segment in LS1, LS2, LS3, however, there are distinct differences between LS1 and LS2, LS1 and LS3 during mobilization with grade III force. This study suggested that the mean peak force of the grade III and grade IV mobilization in the L1-L3 was almost similar each other.
