Hydraulic turbines can convert tidal current energy into electric energy, and the addition of a deflector cover to the turbine can improve the efficiency of the turbine's energy harvesting. The angle of the inlet section and the angle of the outlet section of the deflector will further affect the final energy-acquisition efficiency.A threedimensional numerical model for turbine flow field analysis is established, and the RNG k-ε turbulence model is selected by CFD method, and the best angles of inlet section and outlet section are analysed by the method of sliding mesh to obtain the best angle of inlet section and outlet section separately, and then three groups of angles are selected near the best angle of inlet section and outlet section to make orthogonal comparisons. The energy acquisition efficiency of the turbine is calculated at different angles of the inlet and outlet sections of the deflector, and the turbine streamline distribution, velocity and pressure maps are analysed with and without the deflector.The study shows that the deflector can play the role of convergence of the downstream flow, which can improve the efficiency of the turbine energy acquisition, and the maximum energy acquisition efficiency is at the inlet angle of 29° and the outlet angle of 40 °, and the maximum energy acquisition efficiency can be improved by about 32 percent.
In this study, waste corrugated paper was used as carbon precursor with KOH-NaOH mixture (mole ratio was 51:49 and the melting point is 170 °C) as activator to prepare porous carbon at different reaction temperature and different mass ratio of KOH-NaOH mixture/waste corrugate paper fiber. The micro-morphology, pore structure information and composition of porous carbon were analyzed, and the formation mechanism of pores was investigated. The effect of activator amount and pyrolysis temperature on the morphology and structure of porous carbon were studied. The adsorption capacity of porous carbon was evaluated with the methylene blue as model pollutant. The effect of adsorbent amount, adsorption time and temperature on the adsorption performance of the porous carbon were analyzed. The maximum specific surface area is 1493.30 m2 ·g−1 and the maximum adsorption capacity of methylene blue is 518 mg·g−1. This study provides a new idea for efficient conversion and utilization of waste paper.
In recent years, globalisation has fostered ever more frequent and intimate interactions between states and societies in the Asia-Pacific region. Unfortunately, this has also increased the potential for disputes, particularly regarding international trade and human rights. The Asia-Pacific Dispute Resolution Program, which is run jointly by the Institute of Asian Research and the Peter A. Allard School of Law at the University of British Columbia, seeks to better understand, explain and predict when such disputes will arise, combining stateof- the-art approaches from law, political science, communications, sociology, international relations, economics and business. To manage-and ideally preventsuch disputes, the world is in urgent need of resolution approaches that meet the needs and expectations of the different cultures involved. The objective of the Program is to propose innovative interdisciplinary approaches to dispute resolution that international communities of scholars and policymakers can use to promote intercultural communication and reconciliation.
Offering an apology is one of the common service failure recovery strategies. Previous studies focused on examining the effectiveness of apology from the customer perspective. It is not clear whether and how customers perceive firm remorse after an apology influence their blame attribution and coping behaviors. Integrating a cognitive-emotive model and an empathy model, this research proposes and empirically tests a remorse-empathy-coping model to explain how customers respond to apology after mobile application service failures occur. Specifically, this research examines how perceived firm remorse influences blame attribution and emotional empathy, which subsequently affects coping behaviors (revenge and avoidance) in the mobile app service recovery context. The moderating role of technology anxiety in the proposed model is also identified. Four hundred and fifty-two mobile application service users were recruited for a survey study and the Structural Equation Modeling was used in order to test the research hypotheses. Our findings show that perceived firm remorse negatively influences blame attribution but positively influences empathy. Empathy negatively affects revenge and avoidance behaviors. In addition, technology anxiety moderates the effect of perceived firm remorse on blame attribution. The negative effect of perceived firm remorse on blame attribution becomes weaker when technology anxiety increases.
Introduction
Frontline employees (FLEs) play a very important role in service delivery due to the interactive nature of the service encounter. They span the boundary between the firm and its customers and service firms rely on their FLEs to deliver their promise and create a favorable company image to customers (e.g., Bitner et al., 1990). Considerable previous research addresses how effective management practices and supportive work environments will induce positive attitudinal and behavioral responses of FLEs, which will, in turn, contribute to the positive customer perceptions of the service providers (e.g., Hartline and Ferrell 1996). In other words, the relationship quality or the exchange quality of the employee-organization interface will have a spillover effect on that of the customer-organization interface. But the question examined here is: can this spillover effect occur in an opposite way? In other words, will firms’ treatment of customers shape the employees’ relationship with their firms? With a few exceptions, limited research has paid attention to this inverse relationship. The purpose of our research is threefold: (1) to investigate whether employee perception of customer injustice can influence employees’ psychological contract violation with the firm, (2) to examine whether role conflict mediates the relationship between customer injustice and psychological contract violation, and (3) to explore the moderating impacts of customer identification on the mediation effect of role conflict.
Method
We conducted an experiment using a 2 (customer injustice: high vs. low) x 2 (customer identification: high vs. low) between-subjects factorial design. Two hundred participants were recruited from Amazon Mturk. Twelve responses were deemed unusable and excluded from the study, resulting in a final sample size of 188 (53.7 % female; age ranging from 18 to 65). Each participant was randomly assigned to one of the four experimental scenarios that corresponded to a combination of the two manipulated factors at either high or low level. All manipulations worked as intended. To analyze the moderating effect of customer identification via role conflict, we used the procedure of Hayes (2013) to estimate a conditional process model. We also controlled for the effects of empathy, income, and ethnicity. To test whether the indirect effect of injustice on contract violation is moderated by customer identification, an index of moderated mediation proposed by Hayes (2014) was calculated. To test whether this index is statistically significantly from zero, a 95% confidence interval was calculated for this index by bootstrapping 5,000 samples. The confidence interval of this index is .0162 to 1.1105, indicating the indirect effect is significantly moderated by identification. The results showed that the indirect effect of customer injustice via role conflict on contract violation is only significant (p< .05) when customer identification is high. In other words, when customer identification is low, the effect of injustice on contract violation is not mediated through role conflict.
Research implications
Our research provides empirical evidence that FLEs are sensitive to the treatment of customers by the firm. The traditional wisdom in the sales literature is that “if you treat your employees well, they will treat your customers well.” Our study complements this “trickle-down effect” in the extant literature and demonstrates a “bottom-up effect” that the firm’s unfair treatment of customers will adversely influence employees’ relationship with their firm. Our research also offers important insights into why customer injustice may lead to FLEs’ perceived psychological contract violation with the firm. Previous sales research suggests that role conflict can be influenced by an organization’s structure and culture as well as salespeople’s job characteristics (Singh 1998; Barnes et al. 2006). Our study complements these findings and identifies perceived customer injustice as a new role stressor of FLEs. In addition, our research reveals that the mediating effect of role conflict is moderated by customer identification. Customer identification increases the likelihood that customer injustice would manifest in a psychological contract violation via increased role conflict. The findings of this research also have several managerial implications. First, service and sales managers should be aware of the negative consequence of unfair customer treatment by the firm and how it may eventually jeopardize employees’ relationship with the firm. Second, managers should consult with their FLEs when implementing any new customerfacing policies to understand how these policies would impact FLEs’ other duties of serving customers. Finally, FLEs may form strong identification with their customers, which may amplify the negative consequence of customer injustice on psychological contract violation. Managers should try to counteract FLEs’ over-identification with customers by increasing organizational identification.
The global apparel market is estimated to increase from US$1,105 billion in 2012 to US$2,110 billion in 2025 (Statista, 2014), with women’s wear accounting for approximately 55% of the total within the United Kingdom (UK) (Verdict, 2015). In 2013 and 2014 market research performed by Mintel identified the ‘shopping experience’ as one of the key factors in women’s shopping habits, noting that consumers aged 16-24, in particular, tended to browse online but to buy in-store, still seeing shopping for clothes as a day out with friends (Mintel, 2013). Nevertheless, the growing influence of social media was noted, and by 2015 this age group had overtaken the 25-34 year olds to become the main online clothes shoppers. Despite this, young people aged 16-24, all of whom potentially qualify as digital natives, still show a preference for shopping in-store (Mintel, 2015), although preliminary research indicates that more of them are now shopping alone than with friends. This suggests that there has been a shift in consumer shopping habits within the youth sector, with less importance being placed on the shopping experience. Given that, this study aims to explore the social media behaviours of the youngers aged between 18-24 with a particular focus on fashion consumption.
Crowd sourcing has been identified as an emerging practice found in several sectors including fashion (Yeomans, 2013). Preliminary research suggests that the shift is just a perceived one and that technology savvy young fashion consumers are using smart-technology to upload ‘chelfies’ (‘selfies direct from the changing rooms’) to crowd source opinion about proposed purchases (Soar and Torn, 2015), using social media to replace ‘physical friends’ with ‘digital friends’. To explore this phenomenon further, this study employs qualitative research method and uses semi-structured interviews. The result of this research provides evidence of crowd sourcing behaviours via social media, as well as indicates the complex communication mechanism that embeds within fashion consumption among the generation of the youth.
Brand communities have been increasingly used by marketers to build brands. A brand community can be defined as a “…group of consumers with a shared enthusiasm for the brand and a well-developed social identity, whose members engage jointly in group actions to accomplish collective goals and/or express mutual sentiments and commitments” (Bagozzi and Dholakia, 2006, p. 45). Recent research on brand communities has begun to identify the importance of consumers’ psychological processes in regard to developing successful brand communities. Based on the flow theory from positive psychology, we propose that flow could be generated by brand community characteristics and plays an important role in influencing brand community members’ attitudes toward the brand. Specifically, we propose a model that identifies brand community characteristics (i.e., community cohesiveness and information quality) that produce flow experience and how the flow experience impacts brand identification and brand loyalty.
Members from 31 automobile brand communities participated in this survey study, and 580 validated questionnaires were returned. Structural Equation Model was used to test the research hypotheses. The results show that community cohesiveness and information quality positively directly influence brand identification and also indirectly influence brand identification via flow. Flow also positively influences members’ brand identification and, subsequently, impacts brand loyalty. The results from our research contribute to the branding, brand community, and flow theory literature.
In the present study, the plantlets in vitro of Paeonia suffruticosa ‘Wu Long Peng Sheng’ were used as laboratory materials. The proteome during adventitious root induction process was investigated to sift the related proteins by two-dimensional electrophoresis and mass spectrometry. The results indicated that the protein spots were concentrated in the acidity gel region (pH 4 - 7) and the spots number had a dynamic change ranged from 373 to 462 at the process of root induction (0 – 7 d). 8 spots significantly changed were analyzed with a mass spectrometer and identified using associated software and databases. The peptide information of the 8 spots was similar to the ATP synthase β-subunit of P. suffruticosa (Spots 1 - 4 and 8), P. tenuifolia (Spots 5), P. californica (Spot 6) and P. brownie ( Spots 7) r espectiv ely. T he expression levels of protein spots 1, 4, 5, 6 and 7 was dramatically downregulated, and that of protein spots 2 and 3 had a slightly opposite tendency on the 3rd day. The obviously decreased period is particularly interesting as it was consistent with the induction period of adventitious root primordial of tree peony plantlet in vitro. The ATP synthase β-subunit could be consumed for assembling the ATP synthase in order to supply energy to the rooting process. Therefore, we speculated that the ATP synthase β-subunit was involved in adventitious root initiation of tree peony plantlets in vitro and we expect that further studies should be carried out in order to export its action mechanism.
4U 1323-62, a low mass X-ray binary with an orbital period of 2.94 hr, exhibits periodic X-ray dips, which are due to absorption by the bulge of the outer accretion disk. The purpose of this study is to search for orbital period changes using archived X-ray data over a time span of 20 years. We present our preliminary results from analyzing light curves observed by RXTE, BeppoSAX, XMM-Newton and Suzaku. We used the method proposed by Hu et al. (2008) to estimate dip center time and adopted the Observed - Calculated method to measure changes in period. We obtained an orbital period of 2.941917(36) hr and a period derivative of _Porb=Porb = (-9.9 ± 3.5) X 10-7yr-1. The F-test result shows that the quadratic ephemeris is describes the evolution of the dip phases better than the linear ephemeris at a greater than 95% confidence level. More X-ray data collected from the early 80s will be included to further rfine the orbital ephemeris.
Introduction Driven by the rapidly evolving media landscape, firms extensively use social media to engage with their customers (Avery et al., 2010). Today, social media is an integral part of an individual’s daily life, which makes a vital venue through which companies connect with customers (Men & Tsai, 2011; Utz, 2009). Given the increased use of social media, recent studies have investigated how social media cultivates customer relationships with celebrities and/or media personalities (e.g., Smith, 2010). In light of the effectiveness of social media as a marketing tool, it is noteworthy to analyze the source power of celebrities and social relationships and consider how to take advantage of the power. The parasocial relationship is founded upon the communication process, which is an important factor in understanding the relationship between media and users. Parasocial relationships differ according to the motives for using social network service (SNS), while connection and attachment to celebrities, such as having empathy for a particular celebrity, is affected by celebrity source credibility. (Ohanian, 1990). The purpose of this study is to clarify the relation between parasocial relationships and customer equity in the social media context. The study investigates effects of motivations to use SNS and source credibility on parasocial relationships, as well as the effects of parasocial relationships on attitude and customer equity, and customer lifetime value. Theoretical Frameworks In this study, parasocial relationship refers to a virtual intimacy between a media personality and the media users, in other words, it is a psychological, interpersonal relationship unilaterally formed by users based on proximity, similarity, and attraction to the media personalities (Rubin & Step, 2000). When a parasocial relationship is formed, the media consumer appreciates the values and motives of the media character, often viewing him or her as a counselor, comforter, and model (Horton & Wohl, 1956). When using an SNS, users’ communication habits and their selection of social network services vary according to their motives, which in turn affect the parasocial relationships with celebrities via SNS. Motives for using SNS, specifically, information seeking, entertainment, and social connection may have a positive relationship with parasocial relationships. Source credibility, the positive characteristics of a communicator that affect the receiver’s acceptance of a message, positively influences parasocial relationships (Ohanian, 1990; McCracken, 1989) based on expertise, trustworthiness, and attractiveness of the media celebrities. In the social media context, a parasocial relationship has positive influence on attitude toward using an SNS. Social media users engage in finding people with whom they have an offline connection (Ellison, Steinfield, & Lampe, 2007). Social media enables individuals to connect with others all around the world easily, it is not surprising that parasocial relationships influence users’ attitude toward using social media, offering environments to enhance connections (Byod & Ellison, 2008). Further, it is worthwhile to note that parasocial relationships may have a positive influence on customer equity. The key to customer equity lies in understanding the customer lifetime value concept, which refers to the net present value of a customer’s profit stream (Rust, Lemon, & Zeithaml, 2004). Parasocial relationships positively influence brand, value and relationship equity, with the emergence of brands as one of the key organizational assets (Gummesson, 2004). Parasocial relationships explain relationships between individuals and brands, product, symbols, objects, and corporate identities. Such relationships allow individuals to have bonds with brands, trademarks and other symbols, politicians, sportsmen or even actors (Gummesson, 2004). Thus, they positively influence customer equity including brand equity, value equity, and relationship equity. Focused on effects of motivations to use SNS and source credibility on parasocial relationship as well as the effects of parasocial relationship on attitude, customer equity, and customer lifetime value, this study tests the following hypotheses: H1: Motivations to use SNS will have a positive influence on parasocial relationship. H2: Source credibility will have a positive influence on parasocial relationship. H3: Parasocial relationship will have a positive influence on attitude toward using SNS. H4: Attitude toward using SNS will have a positive influence on customer equity. H5: Parasocial relationship will have a positive influence on customer equity. Methods This study used a survey to investigate key questions about the associations between parasocial relationships and customer equity. A total of 350 social media users recruited from Hong Kong and Macau in China participated in the survey. Of the 350 participants, 129 were men (36.9%) and 221 were women (63.1%), with ages ranging from 21 and 35 years old (mean = 25.6 years). This study measured motivations for using SNS on a five-point Likert scale (1 = strongly disagree; 7 = strongly agree), which was adapted from an existing motivation scale (Leung, 2009; Leung & Wei, 1998; Sheldon 2008). To measure source credibility, this study used a five-point Likert scale, which was also adapted from an existing source credibility scale (Eisend & Langner, 2010; Priester & Petty 2003). Parasocial relationships were measured on the basis of user responses to 17 items on an existing five-point scale that assessed parasocial relationships (Koeppel et al., 1993). This study measured attitude toward using SNS through an existing scale (Venkatesh, Morris, Davis, & Davis, 2003). Customer equity was measured using an existing five-point scale (Keller, 2003; Rust et al., 2004) that elicited user responses to 13 items. Customer lifetime value (CLV) was calculated only for the customers in the sample, and CLVs were calculated separately before the average was taken by using the equation below: The CLVij of customer i to brand j, is given as: Tij= Frequency of purchases by customer i for a specific period of time dj= The rate of discount offered by company j fi= Annual average frequency of purchases by customer i for a certain period of time Vijt= The amount of purchase of brand j by customer i for a period of time t πijt= Expected profits by purchase unit of brand j by customer i for a period of time t Bijt= Probability that customer i buys brand j in purchase t Results The overall goodness-of-fit for this measurement model was acceptable (Chi-square = 8.218, df = 5, p = 0.145, GFI = 0.992, CFI = 0.991, RMR = 0.095, RMSEA = 0.043). The reliability coefficients of all 20 motivation measures were 0.885, and they were based on three factors of information seeking, entertainment, and building relationships. The reliability coefficients of all 16 source credibility measures were 0.924 with three factors of attractiveness, expertise, and trustworthiness. The reliability coefficients of all 17 parasocial relationship measures were 0.866 with three factors: proximity, similarity, and attachments. The reliability coefficients of all 13 customer equity measures were 0.838 with three factors of value equity, brand equity, and relationship equity. Cronbach’s alpha for attitude was 0.792. The coefficients indicate the acceptable reliability of the measures. Motivations to use SNS showed statistically positive effects on parasocial relationship (β = 0.151, p < 0.001). Specifically, entertainment (β = 0.148, p < 0.01) and building relationships (β = 0.093, p < 0.05) motivations showed significant positive effects on parasocial relationships while information seeking motivation did not show significant effects on parasocial relationships (β = 0.074). Source credibility showed statistically positive effects on parasocial relationship (β = 0.316, p < 0.001). Thus, the results supported H1 and H2. Parasocial relationships showed statistically positive effects on attitude (β = 0.295, p < 0.001) and customer equity (β = 0.272, p < 0.001). Attitude showed statistically positive effects on customer equity (β = 0.172, p < 0.001). Thus, the results supported H3 and H4. Customer equity showed statistically positive effects on customer lifetime value (β = 3.452, p < 0.001). Thus, the results supported H5 (see Table 1, Figure 1). Discussion This study contributes to clarifying parasocial relationships in the social media context and determining the relationships between parasocial relationship and customer equity. This study contributes to the theoretical foundation and implications of parasocial relationships and customer equity. Specifically, motivations to use SNS and source credibility positively influence parasocial relationship. Parasocial relationships have positive effects on attitude and customer equity. Customer equity, in turn, has positive effects on customer lifetime value. The study is the first of its kind on the effects of parasocial relationships on customer equity in the social media context. The study finds that motivations and source credibility are important antecedents of consumers’ parasocial relationships formed via social media. Parasocial relationships have a positive effect on attitude and customer equity, and customer equity leads to increased customer lifetime value. This study suggests that parasocial relationship is one of the strong influential variables on customer equity as it improves customer lifetime value. Thus, marketers should definitely consider parasocial relationship management in the social media context while tailoring their brand communications to their most profitable customers and enhance their customer lifetime value.
The objective of this experiment was to evaluate growth performance in dairy goats (Saanen) fed total mixed ration (TMR) of different nutrition levels. Twenty four growing female goats of 8 months of age were randomly assigned to one of four TMRs; low energy-low crude protein (CP) TMR (control), high energy-low CP TMR (T1), low energy-high CP TMR (T3) and high energy-high CP TMR (T4). The content of total digestible nutrients (TDN) and CP in the control diet were 64% and 12%. The TDN content of the high energy TMR was 72% and the CP content of the high CP TMR was 14%. Feed intakes were 1,194g, 1,060g and 1,124g for T1, T2 and T3, respectively, being higher than control (1,039g). Average daily gain was also numerically higher for T1 (170.2g), T2 (114.5g) and T3 (154.9g) than for control (109.0g). The difference of average daily gain between T1 and control was statistically significant (P<0.05). Although there were no significant differences in feed intake (% of body weight) between treatments, feed conversion ratios showed different responses; T1 (7.01) and T3 (7.26) being higher than T2 (9.26) and control (9.53). The increases of heart girth were 11.8㎝, 10.0㎝ and 11.4㎝ for T1, T2 and T3, respectively, being higher than control (8.1㎝).
The photosynthetic characteristics and water use of WL323MF at 3 irrigation treatments (60㎜, 40㎜ and 20㎜ water were applied at the regeneration period and after mowing, respectively) were studied in Beijing's farmland. The results showed t㏊t there are the diurnal change with "M" shape in the Pn, Tr and Gs of WL323MF and there are the positive corresponding relationship between the ㏊y yield and the water consumption, the WUE. About 60㎜ of irrigation could get about 532.74㎜ of the water consumption and 17925.28㎏/㏊ of alfalfa hay, about 20㎜ only could get about 389.60㎜ of the water consumption and 10450.75㎏/㏊ of alfalfa hay.
The situation, problems and models of forage production and industrialization in Beijing were analyzed, and the strategies were pointed out including: (1) The suitable planting areas for alfalfa, silage com and rye etc should be defined systemically, and the rational harvest time and dry skills should be set up in Beijing plain areas. (2) The perennial forage crops with higher drought resistance should be planted in the waste slope land and barren land. (3) The interplant forage crops in the woodland and orchard should be generalized.
