EXAMINING THE ANTECEDENT AND CONSEQUENCES OF CONSUMER ENGAGEMENT WITH VISUAL BRANDED CONTENT ON PINTEREST

Jhih-Syuan (Elaine) Lin,Kuan-Ju Chen 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

Introduction The social Web is becoming more and more visual. While Facebook remains the leading social networking site (SNS), visual-based platforms such as Instagram and Pinterest have showed a significant increase in the proportion of online users worldwide (Greenwood, Perrin, & Duggan, 2016; Statista, 2017; Pew Research Center, 2017). The trend toward visual communication on SNSs is influenced by the emergence of advanced mobile technologies and the shifting habits of how social media users consume content today. While images displayed on Instagram are past-oriented sharing of memories, or present-oriented displays of creativity, Pinterest presents opportunities for future-oriented inspiration to evolve (Jin, Lin, Gilbreath, & Lee, 2017; Phillips, Miller, & McQuarrie, 2014). Pinterest also serves as a searchable archive of visual content, allowing users to seek and include brand-relevant pins and boards into their own aspirations and inspirations, thus facilitating the sharing of branded content (Phillips et al., 2014). Extant industry reports also suggest that Pinterest users are more likely to image-search for products, interact with sponsored pins, and show favorable attitudes toward advertising, compared with Facebook or Twitter users (McMullen, 2015; Ruscillo, 2017; Williamson, 2015). Considering the benefits of social media for global marketing and the role that imagery plays for developing international brands (Mikhailitchenko, Javalgi, Mikhailitchenko, & Laroche, 2009), this research focuses on the visual aspects of consumer engagement with branded content on Pinterest and investigates how such engagement leads to consumer-brand relationship building and Pinterest-inspired purchase intention. Theoretical Frameworks The extant consumer research has documented the superiority effect of visual content on facilitating persuasion (Childers & Houston, 1984; Miniard, Bhatla, Lord, Dickson, & Rao, 1991). Recent research on social media marketing also suggests that branded content with visual elements help generate favorable consumer responses (De Vries, Gensler, & Leeflang, 2012; Trefzger, Baccarella, & Voigt, 2016). The presentation of branded posts is directly related to the flow construct and trust (Bart, Shankar, Sultan, & Urban, 2005; Hoffman & Novak, 1996). Along this logic, consumer engagement, the degree to which consumers consume, contribute, and create social media content in relation to brands (Schivinski, Christodoulides, & Dabrowski, 2016), is likely to be influenced by brand-related visual cues on Pinterest. While consumption refers to consumers’ acquisition of both brand-created and user-generated content (Muntinga, Moorman, & Smit, 2011), contribution refers to consumers’ inputs to content created by brands or by other consumers (Shao, 2009). Further, creation is the highest level of engagement, which refers to consumers’ generation of brand-related content that could stimulate further consumption and contribution (Muntinga et al., 2011). Therefore, the visually dominant and appealing presentation style, such as appearance, layout, and images, on Pinterest would provide users with high information content, and is likely to increase both active and passive consumer engagement with brands (Bart et al., 2005). Consumer engagement is then expected to encourage social media users’ willingness to actively promote and endorse brand-related content, including organic and sponsored pins. Such volunteer display of their preferred brand-related content is likely to help engender eWOM communication and make such content become more influential in the social Web (Chu & Kim, 2011). As a result, users’ brand-related Pinterest activities are likely to enhance their relationships with brands (Rapp, Beitelspacher, Grewal, & Hughes, 2013) and their intention to purchase from the brands featured in the pins and boards (King, Racherla, & Bush, 2014). All hypothesized relationships are therefore formulated and displayed in Figure 1. Methods To test the proposed conceptual model, an online survey was conducted with participants recruited from a consumer panel administrated by Qualtrics. A total of 467 Pinterest users (58.2% female, Mage = 28.9, SDage = 5.6) comprised the sample, including Caucasian (76%), African American (7.5%), Hispanic (7.4%), Asian (6.9%), multiracial (1.3%), and others (.9%). The participants spent an average of 9.5 hours on Pinterest per week. Smartphones (54.8%) emerged as the most dominant devices for their Pinterest usage, followed by computers (34.9%) and tablets (10.3%). They had an average of 33.7 boards (Range = 1,233), 1,384.1 Pins (Range = 69,000), 930.1 likes (Range = 100,000), 319.0 followers (Range = 44,231), 65.0 following topics (Range = 3,442), 173.0 following people (including brands, Range = 7,000), and 102.0 following boards (Range = 6,000). To note, 78.3% of the participants reported that they made Pinterest-inspired purchases frequently (including 24.8% always, 24.4% usually, and 29.1% often). In addition, the participants were asked to answer questions pertaining to their perceptions of visual cues related to a self-selected brand on Pinterest, engagement with brand-related content, brand endorsing behavior, consumer-brand relationships, and Pinterest-inspired purchase intention (see Table 1). Results To test the proposed hypotheses, a two-step modeling approach following Anderson and Gerbing’s (1988) procedures was employed. The results of confirmatory factor analysis (CFA) showed that the measurement model achieved acceptable fit for the data (χ2 = 1178.30, df = 393, χ2/df = 2.99, RMSEA = .065, SRMR = .054, CFI = .930, TLI = .922). The constructs had good composite reliability (>.70). Factor loadings of the construct indicators were all above .70 with significant t values, which indicated good convergent validity for each of the construct items (Nunnally & Bernstein, 1994). Following Fornell and Larcker’s (1981) criteria, the results achieved satisfactory discriminant validity because the average variance extracted (AVE) for each factor was above .50 and greater than the squared correlations between each pair of constructs. The factor scores were then used to perform a path analysis for hypothesis testing which showed satisfactory fit of the conceptual model (see Figure 2). The results indicated that visual cues positively influenced consumer engagement with brand-related content (β = .68, p < .001), which positively led to brand endorsing behavior (β = .86, p < .001). Consequently, brand endorsing behavior positively enhanced the development of consumer-brand relationships (β = .97, p < .001) and increased Pinterest-inspired purchase intention (β = .48, p < .001). In turn, all hypotheses were supported. Discussion and Conclusion In response to the thriving academic interests in understanding how social media users connect and interact with international brands across SNSs (Hennig-Thurau, et al., 2010), this research sheds light on factors that determine social media users’ active discovery, creation, and distribution of visual branded content and the effects of consumer engagement on social media marketing outcomes. By focusing on Pinterest, the research findings showed that users, both men and women, actively seek inspiration from Pinterest across brand-relevant categories. They are highly engaged, open to brand activities, and ready to take Pinterest-inspired actions in the real world. The visual presentation of branded content plays an important role in generating consumer engagement, which is likely to act as a form of perceived relationship investment and subsequently stimulates brand endorsing and advocacy behavior (Simon & Tossan, 2018). Engaged Pinterest users search and select brand-relevant visual content, including sponsored pins, as part of their self-presentation to others (Phillips et al., 2014). Through such interactions with brands and other like-minded users on the platform, their relationships with brands and purchasing behavior are likely to be further enhanced. This research integrates several important literature streams in the conceptual model and employs a representative adult sample to provide theory-driven and generalizable insights into how visually-focused social media marketing works. Marketing managers face opportunities and challenges that social media and the interconnected international business environment present. Therefore, it is crucial to understand how social media users interact with brands on different platforms in order to tailoring brand strategies accordingly for fostering consumer engagement. Specifically, as Pinterest’s popular visual discovery engine continues to attract myriads of global users, managers should harness the power of visual content marketing and engage current as well as potential consumers on the platform, which could have a significant impact on consumer-brand relationship building and business performance in domestic and foreign markets. Building on the findings of this research, future studies should further delve into the psychological underpinnings and motivations that drive consumer engagement with visual branded content on SNSs across cultures and discover how paid, owned and earned brand communication on visual-based SNSs can help strengthen consumer-brand relationships.

UNFOLDING THE RELATIONSHIP-BUILDING POTENTIAL OF BRAND CHATBOTS FOR SERVICE BUSINESSES

Jhih-Syuan (Elaine) Lin 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07

In response to the increasing deployment of brand chatbots in the service sector, this study developed a conceptual framework to examine the psychological processes through which brand chatbots contribute to relationship building efforts. A 2 (interactivity: high vs. low) X 2 (anthropomorphic conversation style: warm vs. competent) between-subject design was conducted in the context of the coffee service business. The levels of interactivity in the chatbots were operationalized by altering the subdimensions of interactivity: modality (i.e., media richness, response latency), message (i.e., interdependency in message exchanges), and source (i.e., customization of content flow). Different linguistic elements (e.g., terms of address, vocabulary, punctuation, emoticons) were used to construct two sets of scripts that emphasized either warmth or competence of the chatbots. Based on the results of the pretests, four brand chatbots via Facebook Messenger were developed using the platform provided by GoSky AI Inc.

( Chien-pin Lai ),( Yong-syuan Chen ),( Tsung-ho Ying ),( Cheng-yen Kao ),( Hui-ling Chiou ),( Shao-hsuan Kao ),( Yi-hsien Hsieh ) 대한신장학회 2023 Kidney Research and Clinical Practice Vol.42 No.4

Background: Mounting evidence indicates that melatonin has possible activity against different tumors. Pazopanib is an anticancer drug used to treat renal cell carcinoma (RCC). This study tested the anticancer activity of melatonin combined with pazopanib on RCC cells and explored the underlying mechanistic pathways of its action. Methods: The 786-O and A-498 human RCC cell lines were used as cell models. Cell viability and tumorigenesis were detected with the MTT and colony formation assays, respectively. Apoptosis and autophagy were assessed using TUNEL, annexin V/propidium iodide, and acridine orange staining with flow cytometry. The expression of cellular signaling proteins was investigated with western blotting. The in vivo growth of tumors derived from RCC cells was evaluated using a xenograft mouse model. Results: Together, melatonin and pazopanib reduced cell viability and colony formation and promoted the apoptosis of RCC cells. Furthermore, the combination of melatonin and pazopanib triggered more mitochondrial, caspase-mediated, and LC3-II-mediated autophagic apoptosis than melatonin or pazopanib alone. The combination also induced higher activation of the p38 mitogen-activated protein kinase (p38MAPK) in the promotion of autophagy and apoptosis by RCC cells than melatonin or pazopanib alone. Finally, tumor xenograft experiments confirmed that melatonin and pazopanib cooperatively inhibited RCC growth in vivo and predicted a possible interaction between melatonin/pazopanib and LC3-II. Conclusion: The combination of melatonin and pazopanib inhibits the growth of RCC cells by inducing p38MAPK-mediated mitochondrial and autophagic apoptosis. Therefore, melatonin might be a potential adjuvant that could act synergistically with pazopanib for RCC treatment.

Dynamic Symmetrical Components Analysis and Compensation for Unbalanced Distribution Systems

Woei-Luen Chen,Bing-Syuan Lin,Meng-Jie Wang 전력전자학회 2015 ICPE(ISPE)논문집 Vol.2015 No.6

The short circuit fault and the unbalanced three-phase loads are the common reasons causing unbalanced voltage distortion (UVD) in the distribution system. In the past, the decline in electric motor performance and life cycle was a well-known fact caused by UVD. However, the UVD deserves more attention in recent years due to the rapid growth of the wind power penetration in the distribution system. The wind power system operated under the UVD suffers not only the pulsation torque but also penetrates unbalanced current and consequently deteriorates the UVD of the distribution system. This paper presents an approach to dynamically resolve the symmetrical components from the three-phase instantaneous voltages in order to clarify the degree of the UVD for compensation. The vector representation for the symmetrical components involves the information of angular frequency into the steady-state phasor, which can push much of the complexity down on the controller design for compensating the UVD. A dynamic voltage restorer (DVR) is employed as a voltage compensator in the series path of the feeder for refining the percent voltage unbalance of the UVD. The impact of the UVD reduction on a grid-tied 3-kW squirrel cage induction generator (SCIG) shows the effectiveness of the proposed approach.
