Introduction The term “coping”refers to the actions or thoughts that people use to deal with stressful encounters (Folkman, Lazarus, Gruen, & DeLongis, 1986). Coping strategies are adopted to change the stressed person-environment relationship by either confronting and/or by regulating the emotions (Lazarus & Folkman, 1987). Research focusing on coping mechanisms has been a prolific area of study, emerged from a wide range of disciplines including psychology, sociology, and anthropology. However, for marketing researchers, questions still remain about the issue of how coping strategies are manifested in everyday consumption contexts. This represents an important area of research in that consumer coping behavior can determine critical post-purchase outcomes such as re-patronage intention, repurchase intention, and word of mouth (Raghunathan & Pham, 1999). When a service failure occurs, consumers frequently experience negative emotions and make decisions under emotionally taxing conditions (Yi & Baumgartner, 2004). Numerous scholars have made attempts to understand various consumption-related emotions and subsequent conditions corresponding to them (e.g., Raghunathan & Pham, 1999; Richins, 1997; Sujan et al., 1999). However, despite the large volume of studies focusing on consumer emotions, very few studies have examined the relationships between negative emotions with consumer coping strategies (Yi & Baumgartner, 2004). With that in mind, the primary aim of this conceptual paper was to propose a model that delineates consumer coping mechanisms derived from negatives emotions in a service failure and recovery context. Conceptual Model Coping strategies are closely linked with an individual’s attempt to manage a given stressful environment (Lazarus, 1991). Lazarus and Folkman (1984) defined coping as “constantly changing cognitive and behavioral efforts to manage specific external and/or internal demands that are appraised as taxing or exceeding the resources of the person”(p. 141). Menaghan (1983, p. 159) defined coping efforts as “specific actions (covert or overt) taken in specific situations that are intended to reduce a given problem or stress.”Duhachek (2005) defined coping construct as “the set of cognitive and behavioral processes initiated by consumers in response to emotionally arousing, stress inducing interactions with the environment aimed at bringing forth more desirable emotional states and reduced levels of stress.”Thus, the key aspects of coping includes a consequence of emotion, a dynamic process, and behavior and emotional domains of consumer responses (Duhachek, 2005). Implicit in this conceptualization is the idea that links the emotions aroused from a particular circumstance, coping strategies, and subsequent behaviors. As shown in Figure 1, our conceptual model classifies a wide range of negative emotions generated by a service failure that are linked to a set of consumer coping strategies. This will in turn influence subsequent consumer post-purchase behaviors. The behaviors will be either retaliatory (vindictive WOM, brand switching, complaining) or conciliatory (positive WOM, re-patronage intention, repurchase intention) responses. Related Literature When an individual encounters a stressful event, different negative emotions are triggered according to one’s distinct appraisals of the situation (Lazarus, 1991). These appraisals, in turn, affect how the consumer responds to the situation emotionally and behaviorally. These emotions remain powerful until the emotion eliciting problems are resolved. Proposition 1. Cognitive appraisal of the service failure situation evokes negative emotions. While some studies use combined negative emotions to explain resultant consumer behavior, others suggest separate emotion inventories (Lerner & Keltner, 2001) as different emotions trigger huge variation in cognition. Consumer negative emotions that are associated with a service failure condition can be categorized into several subsets (Watson & Clark, 1992). Many studies have utilized a limited number of negative emotions to explain consumer behavior in a service failure context (Nguyen & McColl-Kennedy, 2003). Bonifield and Cole (2006) used an appraisal-tendency framework to predict the underlying mechanism of anger and regret, associated with consumers’appraisals about service failure and their effects on post-purchase behaviors. Yi and Baumgartner (2004) focused on four negative emotions of anger, disappointment, regret, and worry in a purchase context to investigate their linkages to consumer coping strategies. Further, Tronvoll (2011) identified a set of negative emotions experienced in unfavorable service experiences leading to consumer complaint such as shame, sadness, fear, anger, and frustration. Although some marketing theorists consider the emotion of frustration to be an overlap with anger, they can be distinct emotions, especially in the context of service failure, because blaming someone else is different from blaming no particular others (Roseman, 1991). Therefore, the subsequent behavior and adapting coping strategy may differ. Thus, this study distinguished frustration separated from anger. Building on the aforementioned research, this study identified five different categories of negative emotions that are frequently found in a purchase-related situation: anger, frustration, disappointment, regret, and anxiety. Anger associates with feeling of attacking someone or yelling, resulting from an individual to be blamed on of the situation (Lazarus, 1991). Frustration tends to occur when people attribute a goal incongruent event to situational factors (Roseman, 1991). Disappointment refers to the feeling occurred due to the outcome insufficient to meet the expectation (Ortony et al., 1988). Regret is evoked when alternative option seems to be better than the selected one (Zeelenberg et al., 1994). Anxiety is linked to uncontrollable circumstances that are not directly under the purview of the provider or the customer (Ruth, Brunel, & Otnes, 2002). Proposition 1-1. Consumer negative emotions associated with a service failure situation are categorized into anger, frustration, disappointment, regret, and anxiety. Appraisal theorists contend that people use different coping strategies to reduce negative emotions accordingly (Lazarus 1991). In this study, consumer coping strategies were categorized into engagement (problem-focused, emotion-focused) and disengagement categories. Coping strategies in the engagement category involves individuals actively trying to manage, control, or change both problem- and emotion-focused aspects of the stressful person and/or environment transaction (Tobin et al., 1989). Problem-focused coping occurs when an individual tries to manage the source of the stress. Emotion-focused coping refers to where the individual changes the meaning of the event or regulates the expressing emotions (Lazarus & Folkman, 1984). In the disengagement category, mental disengagement strategy involves doing other things to take one’s mind off the problem, denial (refusing to believe that something has happened), distancing (refusing to think about the problem), and escape/avoidance (wishing problem would go away or somehow be over with). On the other hand, behavioral disengagement strategy involves consumers deciding to give up further action as nothing can be done about the situation. They acknowledge that a goal cannot be reached and that further efforts are futile. As the mechanism behind each type of coping strategy differs, the negative emotions generated from varying conditions are linked accordingly. Since anger arises from appraisals of other-responsibility, angry consumers often manifest in confrontive coping, aggressive action towards the blameworthy organization (Smith & Bolton, 2002). With respect to frustration, one is more likely to foster support-seeking coping as this does not imply blame attribution to a particular person or organization (Roseman, 1991), Further, previous work has suggested that person-related disappointment tends to result in confrontive coping behaviors such as direct complaining (Zeelenberg & Pieters, 2004) and behavioral disengagement (Yi & Baumgartner, 2004). On ther other hand, complaining about it or telling others is unlikely take place for regret as this may highlight he or she mistake (Zeelenberg & Pieters, 2004). Lastly, anxiety tends to be associated with escape behaviors (Roseman, Antoniou, & Jose, 1996). Thus, anxiety consumers often are linked with emotion-focused coping such as mental disengagement. In addition, more proactive, problem-focused coping is likely to take place as stated in some other studies (Yi & Baumgatner, 2004). Proposition 2. Negative emotions have differential impacts on consumer coping strategies. Service failure literature indicates that negative emotions influence diverse retaliatory responses. Romani Grappi and Dalli (2012) contended that negative emotions of anger, discontent, dislike, embarrassment, sadness, and worry are associated with behaviors such as switching, complaining, and negative word of mouth. Maute & Dubé(1999) also indicated that customer anger is liked to exit and negative WOM. Likewise, Blodgett et al. (1999) similarly suggested that consumers are prone to spread negative word of mouth when they perceive service failure. However, even if a particular coping strategy is activated, depending on the strategy applied, the subsequent behavior can be changed. Many researchers indicated that when a service failure is not recovered, it is more likely to lead to negative WOM and complaining behavior (Anderson, 1998). Especially, WOM behavior is more emotion-driven responses (Sundaram, Mitra, and Webster, 1998). Therefore, vindictive WOM behavior is more likely to occur when the emotions are not handled properly. In addition, Kau and Loh (2006) stated that dissatisfied customers who do not directly complain to the firm about their negative experiences may not only engage in vindictive word of mouth behavior, but also switch to another brand. Sabharwal, Soch and Kaur (2010) also suggested that dissatisfied non complaints are likely to exit the service provider more easily resulting in brand switching. Bonifield and Cole (2007) identified conciliatory behaviors to include positive WOM, willingness to return to a service provider, and feeling sympathy for the service provider. Blodgett et al. (1993) suggested that when service failure is recovered, positive word of mouth will take place. Voight (2007) revealed that when certain platform is provided for customers to express their feeling regarding their purchase, customer loyalty increases. Proposition 3. Coping strategies lead to either retaliatory responses or conciliatory responses. Proposition 3-1. Disengaging coping strategies are associated with vindictive WOM, brand switching, complaining behavior more than engaging coping strategies. Proposition 3-2. Engaging coping strategies are associated with positive WOM, re-patronage intention, re-purchase intention. Additionally, our model proposes two individual characteristics as moderators: self-efficacy and self-band connection. Especially, those with high self-brand connection are assumed to counter-argue negative brand information in a service failure situation as this concept captures a strong “self”relevant emotive tie between the brand and the consumer (Escalas, 2004). We contend that these consumers would use prior brand knowledge to neglect their negative emotions and make more brand favoring attributions following service failure. Therefore, depending on the the previous connection with the brand performing the service failure, corresponding coping strategy may change. As self-efficacy relates to the belief that an adequate coping response is available, both factors should relate to the strategies consumers use to cope (Sujan et al., 1999). Proposition 4. Individual characteristics such as self-efficacy and self-brand connection moderates the relationships between negative emotions and coping strategies. Conclusions This paper integrates a broad range of literature into a conceptual framework that delineates consumer coping strategies in a service failure and recovery context. In so doing, the model establishes clear categories for classifying negative emotions consumers experience in a service failure situation into testable elements, and it is argued that although the concept of coping is not a simple one, it should be central to any examination of the service failure and recovery phenomenon. Also, the proposed model considers where marketers’recovery efforts should be directed by describing the ways in which consumers cope with a service failure. How a firm responds to its customers when a service failure occurs can say more about that firm than any other customer interaction. If handled well, it can cultivate emotionally intense relational outcomes. However, if the firm handles the situation badly, it may cause highly negative reactions with customers taking their feedback to online reviews and social media conversations in a way that can seriously damage the firm’s reputation. Future research is needed to empirically test and extend the proposed model. Further empirical research in a particular service setting would advance marketing research as well as be of great managerial significance.

In recent years, leading digital technology companies have shown a strong interest in enabling children to send electronic word of mouth (eWOM). Recasting children from passive to active participants in marketing communications, this shift expands children’s marketing practices from how a company influences children via traditional marketing communications to how children influence a company’s marketing practices through eWOM. This paper aims to enhance our understanding about the use of children’s eWOM in marketing communications when children’s eWOM and children’s marketing begin to intersect. The eWOM literature demonstrated the effects of eWOM on product sales without identifying the sender (King, Racherla, & Bush, 2014). The extension of the effects from aggregated sender to children needs careful study in light of children’s marketing literature which showed children have distinct characteristics in the context of traditional marketing (Cross, 2002). In this study, we examine the positive expectation of business impact that explains firms’ adoption of children’s eWOM and further investigate the normative concerns about the social influence of children’s eWOM.

Introduction What is fast fashion? Does this term just define all the latest or the most popular or the most famous clothes? In reality, this social phenomenon goes beyond the conventional notion of industrialized fashion and carries more importance than is implied by this view. Fast fashion, defined as “the retail strategy of adapting merchandise assortments to current and emerging trends as quickly and effectively as possible” (Sull & Turconi, 2008, p. 5), has received a great amount of attention from fashion marketers and consumers since its inception during the 21st century (Tokatli, 2008; Jang et al., 2012). The purpose of this study was to deepen our understanding of fast fashion consumers. Based on the review of related literature, the key variables related to fast fashion consumers were categorized into three dimensions: consumer characteristics (i.e., fashion leadership, price consciousness), consumer awareness (i.e., awareness of sustainable practices of fast fashion retailers, perception of fashion democratization), and attitude toward fast fashion retailers. The three dimensions were examined in a sequential manner to assess the power of each set of antecedents in explaining college students’ repatronage intention of fast fashion retailers. Related Literature While fast fashion retailers have experienced a huge financial success mainly due to their affordable and accessible fashion products, they have also been harshly criticized by some members of the public because of their lack of corporate social responsibility. Indeed, fast fashion retailers’ low cost and efficient supply chain management systems have had negative effects on the environment, society, and people (Barnes & Lea-Greenwood, 2006; Bruce & Daly, 2006; Ro & Kim, 2009). The U.S. Environmental Protection Agency (EPA) announced that about 14.3 million tons of textiles were generated in 2012, making up 5.2 percent of total municipal solid waste. Such massive textile waste has been attributed to fast fashion retailers because the cheap and trendy items they produce encourage consumers to make frequent purchases and to frequently dispose of unwanted clothing. Furthermore, several fast fashion retailers (e.g. Gap and Forever 21) have been criticized for the use of child labor and the sweatshop-like conditions of their factories (Ramishvili, 2012). Moreover, some fast fashion retailers have been involved in intellectual property lawsuits because they replicated the runway designs of prominent designers to produce knock-off products (Pous, 2013). In response, a few fashion experts claim that fast fashion retailers destroy fashion because the styles produced lack of aesthetic expression and creativity (Choufan, 2013). However, these issues are not solely a problem associated with fast fashion retailers. In fact, the entire fashion industry is responsible for adverse environmental and societal consequences to some extent. Traditional fashion retailers (e.g. Diesel, Levi’s, Dolce & Gabbana, Chanel, Hermès) also generate huge amounts of textile waste along with hazardous waste that results from the chemical materials used in production processes. Their products are also manufactured in developing countries to keep production costs low. They also may not pay attention to the labor environment. Therefore, traditional fashion retailers along with fast fashion retailers have responsibilities related to sustainability issues (Casey, 2014; Greenpeace, 2013). Nevertheless, fast fashion retailers have received the majority of the public’s criticism regarding these issues. Contrary to a popular belief, fast fashion retailers have taken some steps to apply the concept of sustainability into their business practices. For example, H&M collects unwanted garments for recycling, uses recycled or reused materials for producing new garments and uses organic cottons (Lanyon, 2013). Other fast fashion retailers like Zara, Topshop and Uniqlo as well as H&M also have launched eco-friendly collections (MacDonald, 2012). Moreover, H&M, Zara, Mango and Uniqlo have committed to eliminate the release of toxic chemicals by 2020 in response to Greenpeace’s Detox campaign and to public pressure (Greenpeace, 2012). Furthermore, fast fashion retailers are also paying attention to labor issues. For instance, after more than 1,100 people died from the Rana Plaza building collapse on April 24th in 2013 (Chua, 2013), major fast fashion retailers signed the Accord on Fire and Building Safety in Bangladesh. This accord indicates these retailers agree to be responsible for the working environment for employees in apparel factories in Bangladesh. Although their ultimate goal might be to increase their sales by recovering their brand images damaged by unfavorable media coverage, it is clear that movement toward sustainable practices will minimize the negative impact of their business practices on the environment and society and encourage other retailers to incorporate sustainable practices. In spite of the harsh criticism directed at fast fashion retailers, consumers still like wearing fast fashion products considering that fast fashion retailers have continuously expanded their businesses worldwide and have been successful. Prior researchers interested in fast fashion retailers have focused on supply chain management issues (Barnes & Lea-Greenwood, 2006; Mihm, 2010), the value of fast fashion (Cachon & Swinney, 2011), and indentifying business strategies of a particular fast fashion retailer (Ferdows, Lewis, & Machuca, 2005; Ghemawat, Nueno, & Dailey, 2003; Tokatli, 2008). However, few researchers have theoretically explained why consumers still like fast fashion products and visit fast fashion retailers. With that in mind, the present study identified various factors that positively influence consumer attitude and their patronage intention toward fast fashion retailers. Furthermore, although fast fashion retailers have positive motivations toward consumers (e.g. provide inexpensive fashionable items,participate in sustainable practices), consumer research has highlighted their negative effects on the environment and society (e.g., Morgan & Birtwistle, 2009). Methods An online self-administered survey methodology was employed with a purposive sample of U.S. college students who had shopped at fast fashion retailers. A total of 154 usable responses were used for data analysis. The click through rate was 79.79%. Exploratory factor analysis and hierarchical regression were used to examine the interrelationships among the three dimensions of antecedents (consumer characteristics, consumer awareness, consumer attitude) and repatronage intention. The measurement items employed were developed based on previous literature. All items were reviewed and modified to fit the context of this research: consumer attitude and patronage intention toward fast fashion retailers (Madden, Ellen, & Ajzen, 1992); perception of fashion democratization (PFD) (Dubois, Czellar, & Laurent, 2005); fashion opinion leadership (Flynn et al., 1996; Goldsmith & Hofacker, 1991); and price consciousness (Lichtenstein et al., 1993). The items for measuring awareness of sustainable practices of fast fashion retailers (ASP) were created based on news articles presenting sustainable practices fast fashion retailers actually engaged in. Participant Characteristics Among the participants, 48.1% were majoring in a fashion related area (e.g. fashion design, retail merchandising). The majority of the participants were female (85.1%). Most participants (92.2%) were between 18 and 25 years old. With respect to ethnicity, 63.0% were Caucasian. Approximately half of the participants (52.6%) reported that they earned less than $10,000 annually. Also, 26.0% of the participants shopped at fast fashion retailers once a month. Results A weighted least squares (WLS) hierarchical regression analysis was used for data analysis. Fast fashion shopping frequency was used as a weight variable as it is related to the variability in the dependent variable. The results revealed that: (a) fashion leadership positively influenced repatonage intention (Model 1); (b) after controlling consumer characteristics, PFD played a significant role in increasing variance explained in repatonage intention (Model 2) and (c) after controlling consumer characteristics and awareness, consumer attitude was found to be a significant predictor, partially mediating the linkages from fashion leadership and PFD to repatronage intention (Model 3). Implications and Conclusion Our findings suggest that fashion leadership plays an important role in the fast fashion market because it initiates the acceptance of new trends and leads to diffusion of new fashion. Prior research suggests that fashion leaders (versus followers) are willing to take risks in trying new items offered by fast fashion retailers, are interested in fashion information, tend to retain fashion items for socializing for a short period of time and need various and unique fashion items (Goldsmith, Freiden & Kilsheimer, 1993; Kang & Park-Poaps, 2010). Given that fast fashion retailers promote frequent purchases and decrease the financial burden by offering new products on a weekly basis and charging low prices, our finding is consistent with fashion leaders’ characteristics prior research identified. Another important finding is that the role of PDF in defining fast fashion consumers. Fast fashion products look similar to high-end products, but are comparatively inexpensive because the fast fashion retailers apply or copy high-end designs into their products and use cheap materials (Niinimäki, 2009; Reinach, 2005). Also, fast fashion retailers open tremendous stores across the world, which make fashion more accessible to consumers globally. As a result, fast fashion retailers accelerate the fashion democratization and it means that both concepts of fast fashion and fashion democratization are highly related. As Wang (2010) stated, “fast fashion’s soul is to make fashion democratized with its low price and speed” (p.10). Further research is needed to extend and corroborate the findings of this study.

This study assessed the degree of marketplace inclusion inherent in the distribution of grocery stores in the Detroit Metropolitan Area; to account for spatial effects such as spatial heterogeneity, phenomena rarely considered in prior marketing literature, geographically weighted regression and geographic information systems were employed.

Emotion has been discussed as a key element in the purchase decision process across several products and services by several researchers (Bagozzi, Gopinath, & Nyer, 1999; Kang, Jin, & Gavin, 2010; Lee & Park, 2013). Although a variety of products and services have been utilized to address the relationship between emotions and the purchase decision process, books, especially an online-book purchase environment, have been neglected in existing research of the relationship between emotions and the purchase decision process. Thus, the purposes of this study are 1) to investigate how book covers influence consumers’ purchase decisions in an online setting, 2) to examine the influence of two different criteria of book covers (the color of the book cover and the picture or photo on it) on consumers’ emotions of delight, and 3) to explore the cross-cultural differences (i.e., Japan vs. France) in the online book purchase decision process. Emotion is referred to “an affective, subjective, experimental, temporary, multidimensional phenomenon and a source of motivation caused by exogenous factors to the individual that interact with the process of treatment of the collected information for the purpose of experience of consumption” (Graillot, 1998, p. 12). In marketing, emotion is considered to be the beginning of the choice made by consumers (Derbaix & Pham, 1989), and many researchers have tried to find dimensions of emotion which better explain the consumer’s purchase decision process, such as circumstances (e.g., hope, relief, and joy), external cues (e.g., like, dislike, and anger), or self-created cues (e.g., regret, shame, and guilt) (Roseman, Antoniou, & Jose, 1996). In order to fill in gaps from previous research, in this study we present the following research hypotheses: H1: There will be a positive relationship between the color of the book cover and the consumer’s emotion of delight when purchasing a book from an online bookstore. H2: There will be a positive relationship between the picture or photo on the book cover and the consumer’s emotion of delight when purchasing a book from an online bookstore.H3: There will be a positive relationship between the consumer’s emotion of delight and a book’s perceived usefulness when purchasing a book from an online bookstore. H4: There will be a positive relationship between a book’s perceived usefulness and the purchase of the book. H5: The impact of the book cover on the purchase decision process will vary by country. Japan and France were chosen as the countries for the study as they are significantly similar in terms of the size of the book market on the global stage (Oricon, 2015), however the two countries are very dissimilar in terms of culture. In addition, there is no existing research that compares consumers in these two countries in an online book purchase setting. A total of 398 usable date sets were collected in Japan (n = 191) and France (n = 207) using a questionnaire survey. Two sets of questionnaires were developed in Japanese and French for the respondents and the respondents were randomly chosen for this study. All measurement items of each construct (i.e., the importance of the color of the book cover, the importance of the picture on the book cover, the emotions of delight, the perceived usefulness of the book, and the book purchase) were adopted from previous studies and measured using a 5-point Likert scale. To test the proposed research framework, in this study we developed a structural equation modeling method. Multigroup confirmatory factor analysis was conducted to test construct validity, which showed satisfactory evidence of convergent and discriminant validity. Based on Table 1, there is no significant relationship between the color of the book cover and the emotion of delight, therefore Hypothesis 1 was rejected. On the other hand, Hypotheses 2 (the relationship between the picture on the cover and the emotion of delight), Hypotheses 3 (the relationship between the emotion of delight and a book’s perceived usefulness), and Hypotheses 4 (the relationship between a book’s perceived usefulness and the book purchase) were found to be statistically significant. Finally, Hypothesis 5, indicating that the impact of the book cover on the purchase decision process varies across countries, was supported. In other words, the χ² difference test between the two countries revealed that an unconstrained model indicated a significantly better model fit than a fully constrained model (Δχ²(7) = 117.58, p < .001), indicating the evidence of differences in the path relationships between the two countries (Laukkanen et al., 2013). Since Hypothesis 5 was indicated to be significant, a further analysis of each path from Hypothesis 1 to Hypothesis 4 was conducted. This revealed that only the relationship between a book’s perceived usefulness and the book purchase was significantly different by country (Δχ²(1) = 3.91, p < .05). The study provides meaningful academic implications. This study examines the influence of the book cover on consumers’ emotions, which lead to the actual purchase of the book in an online setting and accurately explains the role of consumers’ emotions in the relationship. Furthermore, this study proved that the relationship between the book’s perceived usefulness and the purchase of the book was different by country. Given this, marketers should develop tailored marketing strategies for the two countries. For French consumers, practitioners should focus more on the usefulness of the book itself, such as the meaning of the book to readers, the impact of the book on readers, the potential for improving reader’s knowledge andhappiness, etc. In other words, marketers should emphasize and promote the concept of the usefulness of the book itself rather than the design components, such as the color of the book cover. Additionally, consumers’ emotions of delight have a significant role on the online book purchase decision, therefore promoting and arousing consumers’ positive emotions, for example, with music, easy transactions, easy access, etc., may be critical while shopping for books online.

As consumers take greater control over products and brands they consume, electronic word-of-mouth (eWOM) and user-generated content (UGC) are now being considered as one of the most critical product sources for consumers. Most notable in recent years has been the widespread emergence of eWOM in social media. The proliferation of a variety of social networking sites (SNSs), propelled by the development of mobile technologies (e.g., smartphones), has allowed consumers to share, more quickly and easily than ever before, product information, reviews, and consumption experiences. Perhaps one of the newest and most effective ways to communicate brand information and experiences in digital environments is the ‘brand-selfie.’ Every day, millions of selfies (i.e., a photograph that one has taken of oneself, typically with a smartphone or webcam and shared via social media) are taken and then posted on a variety of SNSs all over the world, providing people the opportunity to show multiple facets of the self (Bazarova et al., 2013). Further, there are consumers who voluntarily post selfies with brands/products they possess (so called brand-selfies) and brand-related hashtags (e.g., your #brand). Through brand-selfies, consumers not only express themselves by connecting with and extending through brands, but also influence peer consumers’ brand attitudes and purchase decisions by sharing brand information. In order to better understand how the selfie can succeed on SNSs as a new form of eWOM, in the present study, we attempt to identify key predictive variables that may lead consumers to post brand-selfies and engage eWOM in social media. We do so by comparing how such variables differ between those who post brand-selfies and those who do not. Specifically, this study examines whether brand-selfie-posting behavior is influenced by two individual difference factors (i.e., narcissism and materialism), and whether it is associated with consumers’ beliefs that SNSs are brand/product information sources. Using a survey administered by an online panel, a total of 305 participants who had had the experience of taking and posting selfies on SNSs participated. Discriminant analysis identified the characteristics of consumers who post brand-selfies, and those who do not. Findings suggest that narcissism, materialism, and belief that SNSs are a brand/productinformation source are significant factors in stimulating SNS users’ brand-selfie posting behaviors, and that they could be used to differentiate between brand-selfie posters and no-brand-selfie posters. Of these factors, consumers’ perceptions of SNSs as a source of brand/product information best predicted brand-selfie posting behaviors, followed by materialism and narcissism. Areas for future research are discussed.

Multisided platforms (e.g. eBay, Airbnb, Facebook, Apple’s iOS etc.) are marketplaces to facilitate direct interactions between two or more customer or participant groups and enable the value to customers on one side of a platform typically to increase with the number of participating customers on another side (Hagiu, 2014). Platform is a business model to have the more knowledge of its customers and become more networked (Weill & Woerner, 2015). Collaborative consumption platforms (CCPs) are marketplaces to facilitate sharing activities such as the form of renting, lending, trading, bartering and swapping of goods or services based on Möhlmann’s (2015) definition. The rise of information and communications technology (ICT) such as the internet or mobile apps enables an easy access on CCP, which facilitates peers to trade and decrease transaction costs (Möhlmann, 2015). Although CCPs can create better customer experience than traditional business model, there is asymmetric information among peers, which results in lemons. Boudreau and Hagiu (2008) suggested that platforms owners should reduce lemons problems by establishing technical standards and interfaces, rules and procedures, defining the division of tasks, providing support and documentation and sharing information as non-priced instruments. Some attempts have been made in order to demonstrate online service failure or lemons on the web (Holloway & Beatty, 2003). In the Holloway and Beatty’s study (2003), the typology of online service failures has been provided and demonstrated how online retailers could manage their online service failures effectively. The solution to reduce information problems is signaling of trust about quality such as price, adverting, and warranties (Boulding & Kirmani, 1993). Trust in CCPS is to trust in other peers within the platform to share (Möhlmann, 2015). If a CCP cannot control opportunistic behaviors of peers, the peers participating in the CCP can be harmed as well as the CCP will fail to encourage more peers to participate and thus the social value of the CCP may decrease. It is important to understand decision making process of peers in CCPs and consider the motivations to use CCPs and the contexts at the same time. Enjoyment and economic benefits have a direct impact on behavioral intention to participate in CC in the motivation model by Hamari and his colleagues (2015). We suggest the motivatio ns such as enjoyment or economic benefits can be fit by the specific signals of peers in CCPs. The consumers with different motivations to use CCPs can perceive signals for trust differen tly. The more people pursue hedonic value for CCP, the more they tend to make a decision de pending on heuristics rather than elaborate cognitive process. The more people pursue utilitar ian value for CCP, the more they tend to make a decision depending on elaborate cognitive pr ocessing. We conduct two experiments to examine the fit between motivations and signals of CCPs. The interaction effect between motivations to use CCPs and types of signals is investigated through ANOVA test. People to use CCPs for enjoyment have more usage intention when they are exposed by more reviews rather and CCP with low governance power. On the other hand, People to use CCPs for convenience have more usage intention when they are exposed by high review quality and CCP with strong governance power rather than low governance. Social marketers and public policy makers seek to spread CC for the sake of fostering sustainable consumption behavior and promoting public sharing events (Möhlmann, 2015). Sharing and collaborative consumption can be solutions against global warming, rising fuel and raw material prices, growing pollution, and other anticipatable trends (Belk, 2014). CCPs strive to make people participate to create value of their CCPs based external crosseffect by providing various signals for peers with different motivations. Thus public policy makers should foster CCPs rather than encourage people directly to participate. In addition, public policy makers should give CCPs self-regulation that can decide the types of governance and policies to reduce lemons market problems. Our research contributes to the literature on market failures in CCPs by highlighting the importance of the fit between the motivations to use CCPs and signals. Although people have motivation to participate in CC, they are not willing to participate in CCPs without trust of other peers or goods and services. Thus CCPs need to provide peers with proper signals.

The aim of this study was conducted to investigate the proximate and nutritional compositions including mineral, vitamin, amino acids and fatty acids in Korean yam (Dioscorea batatas DECNE.). Carbohydrate (68.1%) possessed the large single constituent of yam. Small amounts of crude protein (16.9%), crude ash (5.8%) and crude fat (2.0%) contents were found. Yam was found to be good sources of essential minerals such as K (1295.5 mg/100 g), Mg (115.3 mg/100 g), Na (99.0 mg/100 g) and Ca (56.5 mg/100 g) but Zn (0.3 mg/100 g) content was low. Relatively abundant vitamin B1 (11.5 mg/100g) could be observed while vitamin A, B3 and B6 were not found. The amino acid analysis revealed that the yam was superior with respect to glutamic acid (1770.6 mg%), lysine (1210.6 mg%) and urea (550.9 mg%). Essential amino acids were calculated to be 2954.5 mg%. The amino acid profiles showed that yam to be limiting in valine and leusine. Palmitic acid and linoleic acid were the most predominant fatty acids with the value of 31.5% and 41.5%, respectively. And the polyunsaturated fatty acids including linoleic acid and linolenic acid were present in a large quantities in yam. And it also contained higher amounts of unsaturated fatty acids compared saturated fatty acids.

The bioactive compound and antioxidant property of Korean yam (Dioscorea batatas DECNE.) were studied using in vitro methods. Yam available in Korea was analyzed for lycopene, chlorophyll a, b, tannin, phytic acid and total saponin contents. 70% Methanol, 70% ethanol and chloroform–methanol mixture (CM, 2:1, v/v) were used to extract yam. Then the antioxidant activity evaluated through ferrous ion chelating activity, β-carotene bleaching method, lipid peroxidation inhibition and nitric oxide (NO) radical scavenging activity. 70% Methanol extract showed the highest ferrous ion chelating activity and NO radical scavenging activity. And CM extract was the most effective in inhibition of linoleic acid peroxidation evaluated by β-carotene bleaching assay and lipid peroxidation inhibition assay. Based on the results obtained, yam is a potential active ingredient that could be applied in antioxidation as well as bio-health functional food to take a good part in prevention of human diseases and aging.

The objective of this study was to investigate the antioxidant activity of Korean yam (Dioscorea batatas DECNE.) by different extraction solvents including 70% methanol, 70% ethanol and chloroform–methanol mixture (CM, 2:1, v/v). Raw yam was analyzed for its color property, total phenol content and antioxidant activity. Yam possessed high L* value and H° value, which were 81.64±2.59 and 83.36±0.15, respectively. Raw yam was found to have great antioxidant activity evaluated through ABTS [2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt] radical scavenging activity, DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, reducing power, and ferric reducing antioxidant power. Total phenol contents of various extracts from raw yam increased in the following order: 70% methanol extract (37.62±0.88 mg CAE/g), 70% ethanol extract (43.38±0.66 mg CAE/g) and CM extract (67.17±0.12 mg CAE/g), respectively. The same trend was also could be found in the ABTS radical scavenging activity, DPPH radical scavenging activity and ferric reducing antioxidant power assays. These results implied that Korean yam might play an important role in antioxidation and serve as the bio-health functional food to take a good part in prevention of human diseases and aging.
