HOW SOCIAL MEDIA INFLUENCE ON CONSUMERS’ LUXURY VALUE PERCEPTION

Bruno Godey,Jungsun Cho 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

Introduction Luxury industry, in addition to feelings, started to provide reasons for consumers to justify their consumption. Also, it helps them to avoid social risks by offering inconspicuous luxury products. For example, ‘Mandarin Oriental Barcelona’ suggests luxury holiday package for people running Barcelona marathon, London cocktail bar ‘Bart’ serves cocktails designed to 'facilitate focus and encourage relaxation', ‘Tiffany’ has dropped the spelled-out brand name from its fashion jewelry line in favor of simple “T”. (Trend watching 2017) Then, what changed consumers' interest? Interestingly, the current expectations of luxury consumers have a lot in common with the features of interdependent self-construal. The we effect of social media can explain this trend. Literature review and Conceptual framework Social Media usage and Interdependent Self-Construal Although earlier research in cultural psychology conceptualized self-construal as culturally determined (Markus and Kitayama 1991), more recent research suggests that independent and interdependent self-construal can also be made temporarily accessible. The most frequently adopted priming procedure to induce self-construal is the procedure by stories about we or I. (Gardner, Gabriel, and Lee 1999; Mandel 2003; Krishna, Zhou, and Zhang 2008; Hong and Chang 2015). We suggest that Social media usage can induce interdependent self-construal because social media users read stories and watch videos of others. Prior findings indicated that participants in interdependent self-construal condition have an equivalent number of thoughts about themselves and others. (Lee, Aaker, and Gardner 2000). Social Media, Interdependent Self-construal, and Consumers’ Luxury Value Perception Consumers’ perceptions of luxury value appear to be determined mainly by Functional, Individual, and Social aspects (Wiedmann, Hennigs, and Siebels 2009). Recent luxury marketing researchers compare conspicuous consumption and inconspicuous consumption, two types of social aspect consumption (Han, Nunes, and Dreze 2010; Eckhardt, Belk, and Wilson 2015). They are interested in Functional luxury value, added to Individual luxury value because small utilitarian additions to a hedonic luxury are often valued more than their stand-alone value (Keinan, Kivetz, & Netzer 2016). These two trends seem to have nothing in common. But when the concept of self-construal is adopted, they have something in common. Namely, interdependent selves, which focuses on others, are the one who cares about both inconspicuousness and utilitarian aspects. We suggest that because of the features of interdependent self-construal, consumers more using social media tend to have a different priority regarding luxury value perception than consumers less exposed to social media. We explore the mediating role of relational interdependent self-construal in this model (Triandis 1989; Cross, Bacon, and Morris 2000). Also, luxury brand company’s social media marketing efforts (Kim and Ko 2012; Godey et al. 2016) have different features. We expected that each social media marketing activity has a different impact on luxury value perception. Interdependent Self-Construal, Reason, Functional luxury value We propose that because of interdependence priming effect of social media, participants who are exposed to social media (social media priming group) tend to rely on both reason and feeling, which in turn set an equivalent value on Functional luxury value (cognitively superior) and Individual luxury value (affectively superior) (Hong and Chang 2015). Interdependent Self-Construal, Social Risk, Inconspicuousness The authors propose that because of interdependence priming effect of social media, participants who are exposed to social media (social media priming group) tend to avoid social risk than participants who are not exposed to social media (no priming group). Study 1: The effect of social media on the balance between self and others. A total of 709 respondents (389 females) participated in this study via Amazon Mechanical Turk (MTurk) They were randomly assigned to one of the two conditions (with social media manipulation vs. No manipulation) The impact of ‘one-time social media use’ Following the previous study (Hong and Chung 2015), we conducted a 2 (social media manipulation: No vs. Yes) x 2 (thought type: self vs other) mixed ANOVA with social media manipulation as a between-subject factor and thought type as a repeated measure. The main effect of thought type is significant (F(1,707) =293.54, p<.000). However, the interaction between social media manipulation and thought type was not significant. (F (1,707) = 0.128, p<.721). So, the result shows that one-time social media use doesn’t manipulate interdependent self-construal. The impacts of ‘chronic social media use’. To check whether chronic social media use can manipulate interdependent self-construal, we conducted a 2 (time spent on social media: Low vs. High) x 2 (thought type: self vs. other) mixed ANOVA. The main effect of thought type is significant (F(1,707) =293.81, p<.000). The interaction between time spent on social media and thought type was significant. (F (1,703) = 6.65, p<.000). Also, we conducted a 2 (communication on social media: Low vs. High) x 2 (thought type: self vs. other) mixed ANOVA. The main effect of thought type is significant (F(1,707) =300.76, p<.000). The interaction between communication and thought type was significant. (F (1,704) = 5.764, p<.000). So, the result shows that chronic social media use manipulates interdependent self-construal. Also, we computed three types of groups, the others-dominant, the balanced, and the self-dominant by modifying past research (Kitayama et al. 2009; Wu, Cutright, and Fitzsimos 2011, Hong and Chang2015). A chi-square test revealed that participants who spent more time and had more communication on social media had more balanced thought type (32.6%, 31.0%) than participants who spent less time and had less communication on social media (24.8%, 24.0%) Study 2: The effect of using social media on luxury value perceptions (SEM) A total of 255 respondents (85 females) participated in this study through Amazon Mechanical Turk (MTurk). The participants were between 18 and 65 years old and lived in the U.S., and the modal age group was 25-34 (43.9 %), followed by 35-44 (25.5%). We conducted exploratory factor analysis (EFA) using maximum likelihood estimation with Promax rotation. The goodness of fit statistics is: ??=707.14, df =377, P<0.0005, ??/df =1.876, CFI=0.95, and RMSEA =0.059. The final CFA model fits well with the data (Hu and Bentler, 1999; Hair et al., 2010). After confirming the measurement model, SEM with maximum likelihood extraction was estimated to test Hypothesis. The goodness of fit criteria of the model meets the proposed thresholds in previous studies: ??=677.97, df =374, P<0.0005, ??/df =1.813, CFI=0.95, and RMSEA =0.057 (Hu and Bentler, 1999; Hair et al., 2010). The SEM model showed each social media activity has a different effect on each luxury value. Interaction positively impacts the functional luxury value (β=0.38, p<.000) but negatively impacts the individual (β= - 0.27, p<.000) and social luxury value (β= - 0.34, p<.000). Entertainment/WOM has a positive effect on individual luxury value (β=0.39, p<.000) and on social luxury value (β=0.32, p<.000). Customization positively impacts the social luxury value (β=0.26, p<.000). We could also find Entertainment/WOM and Customization did not influence the functional luxury value. Only Entertainment/WOM positively impacts relational interdependent self-construal (β=0.32, p<.000) Relational interdependent self-construal positively impacts on individual value (β=0.24, p<.000) and social value (β=0.27, p<.000). We conducted a mediation analysis. Among social media activities, only Entertainment/WOM had a significant positive effect on Relational Interdependent Self-Construal. Study 3: the effect of social media on self-construal and choice between functional value and individual value superior options 454 Responses (304 females) collected via Mturk to stimulate the environment of social media. Respondents are primed on interdependence by social media usage while control group respondents are not primed. The authors checked the validity of the self-construal manipulation effect of social media. Respondents were given a choice task, designed by adopting previous method (Hong and Chang 2015). They were told to imagine that they were going to buy a hand bag. Handbag X is superior on functional (cognitive) dimensions whereas handbag Y is superior on all individual (affective) dimensions. Participants are asked to indicate their choice between two Handbags Choice. A chi-square test revealed that the effect of social media manipulation is not significant on the handbag choice (?2(l) 0.371, p<.309). However, the effect of interdependent self-construal on the participant's’ handbag choice was significant (?2(l) 5.85, p<0.01). As predicted, participants with a higher Interdependent self-construal primed by social media have a smaller preference gap between Functional luxury value and Individual luxury value (F:73.2%-I:26.8%=46.4%), than participants with lower Interdependent self-construal participants (F:82.7%-I:17.3%=65.4%) Study3 supports the results of previous two studies. As individuals communicate more and spend more time on social media, they are more likely to prefer equally for Functional luxury value and Individual luxury. Study 4: the effect of social media on self-construal and choice between conspicuous and inconspicuous options. After the self-construal manipulation with social media, respondents were given a choice task. The choice was designed by adopting previous method (Han, Nunes, and Dreze 2010). Respondents were told to imagine that they were going to buy a handbag. One option has an inconspicuous design whereas the other option is conspicuous design. Participants are asked to indicate their choice between two handbags. Social media manipulation and Handbags Choice. All three chi-square tests revealed a significant or marginal effect of social media manipulation on participants handbag choice with the same pattern. ( ?2(1) = 6.328, p > .032; ?2(1) = 3.086, p > .079; ?2(1) = 1.933, p > .098) As predicted, participants in social media manipulation group prefer the inconspicuous option to the conspicuous option (59.3%>40.7%; 58.9%>41.1%; 60.4%>39.6%) than participants in control group (47.3%, 52.7%; 50.5%, 49.5%, 53.8%, 46.2%). Interdependent-self construal and Handbags Choice. All three chi-square tests revealed a significant effect of interdependent self-construal on participants handbag choice with the same pattern. ( ?2(1) = 4.2, p > .047; ?2(1) = 4.79, p > .029; ?2(1) = 6.11, p > .013) As predicted, participants with higher Interdependent self-construal primed by social media have a equivalent preference about the inconspicuous option and conspicuous option (50%, 50%; 50.8%, 49.2%; 52.4%, 47.6%) than participants with lower Interdependent self-construal(59.6%, 40.4%; 61.1%, 38.9%, 63.9%, 36.1%). Study4 shows that one-time social media exposure can reduce conspicuous consumption. However, as individuals communicate more and spend more time on social media, they become more likely to prefer equally for conspicuous option and inconspicuous option. Contribution In luxury brand marketing, this study sheds light on the balance between two motivations, luxury for self and luxury for others (Kapferer, Jean-No?l, and Vincent 2009) using the concept of self-construal. This research also contributes to the literature on consumers’ luxury value perception (Hennigs et al. 2012; Wiedmann et al. 2009). In general marketing subjects, it adds to the increasing literature on consumer risk and choices between affective and cognitive options. For the luxury brand industry, this study can give marketers a practical idea about choosing social media marketing activities and designing new products. For example, if luxury brand companies promote customers posting opinions on websites, they should know that their activities might advertently affect their sales because interaction negatively influences on individual and social luxury value.

AN APPLIED PREDICTIVE MODELING OF BRAND EQUITY INDUCING SOCIAL MEDIA BRAND-RELATED ENGAGEMENT

Bruno Schivinski 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

This study presents a machine learning approach using conditional inference tree (Ctree) to determine how brand equity can be used to factually engage consumers into social media brand-related activities. Using the Ctree algorithm (Hothorn, Hornik, & Zeileis, 2006), a predictive model was computed using self-reported data on consumers’ perceptions of brand equity (Aaker, 1991) and engagement into social media brand-related behavior (Muntinga, Moorman, & Smit, 2011) from a sample of 690 individuals. The predictive modeling analysis revealed 5 different rules (patterns) that trigger social media brand-related behavior. Each rule comprises behavioral engagement discriminating low, medium, and high levels of consumption, contribution, and creation of brand-related social media content. Additionally, the analysis portrait 5 subtypes of consumers according to their behavior. This study has incremental explanatory power over preceding consumer brand engagement studies, in that it demonstrates how to manage brand equity to factually engage consumers into social media brand-related activities, therefore, generating valuable insights that may be used to support business.

The hG-CSF (human Granulocyte Colony-Stimulating Factor) is a growth and stimulation factor capable of inducing the proliferation of bone marrow cells, several types of leukocytes, among other hematopoietic tissue cells. hG-CSF is used in used to treat anomalies that reder a small number of circulating white blood cells, which may compromise the immune defenses of the affected person. For these reasons, the production of hG-CSF in a bioreactor system using the mammary gland of genetic modified animals is a possibility of adding value to the bovine genetic material and reducing the costs of hG-CSF production in pharmaceutical industry. In this study, we aimed the production of transgenic hG-CSF bovine through the lipofection of bovine primary fibroblasts with an hG-CSF expression cassette and cloning these fibroblasts by the somatic cell nuclear transfer (SCNT) technique. The bovine fibroblasts transfected with the hG-CSF cassette presented a stable insertion of this construct into their genome and were efficiently synchronized to G0/G1 cell cycle stage. The transgenic fibroblasts were cloned by SCNT and produced 103 transferred embryos and 2 pregnancies, one of which reached 7 months of gestation.

Numerical simulation of seismic tests on precast concrete structures with various arrangements of cladding panels

Bruno Dal Lago 사단법인 한국계산역학회 2019 Computers and Concrete, An International Journal Vol.23 No.2

The unexpected seismic interaction of dry-assembled precast concrete frame structures typical of the European heritage with their precast cladding panels brought to extensive failures of the panels during recent earthquakes due to the inadequateness of their connection systems. Following this recognition, an experimental campaign of cyclic and pseudodynamic tests has been performed at ELSA laboratory of the Joint Research Centre of the European Commission on a full-scale prototype of precast structure with vertical and horizontal cladding panels within the framework of the Safecladding project. The panels were connected to the frame structure by means of innovative arrangements of fastening systems including isostatic, integrated and dissipative. Many of the investigated configurations involved a strong frame-cladding interaction, modifying the structural behaviour of the frame turning it into highly non-linear since small deformation. In such cases, properly modelling the connections becomes fundamental in the framework of a design by non-linear dynamic analysis. This paper presents the peculiarities of the numerical models of precast frame structures equipped with the various cladding connection systems which have been set to predict and simulate the experimental results from pseudo-dynamic tests. The comparison allows to validate the structural models and to derive recommendations for a proper modelling of the different types of existing and innovative cladding connection systems.

Background/Aims: Argon plasma coagulation (APC) is the most commonly used endoscopic treatment for gastric antral vascularectasia (GAVE). Endoscopic band ligation (EBL) has emerged as an alternative therapy. Our goal was to evaluate the feasibility,efficacy, and safety of APC and EBL for the treatment of GAVE. This is the first systematic review that included only randomizedcontrolled trials (RCTs) on this topic. Methods: A comprehensive search was performed using electronic databases to identify RCTs comparing APC and EBL for thetreatment of GAVE following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results: Four RCTs were included, with a total of 204 patients. EBL was related to higher endoscopic eradication rates risk difference[RD], 0.29; 95% confidence interval [CI] [0.14, 0.44]; I2=0%) and less bleeding recurrence than APC (RD, 0.29; 95% CI [0.15, 0.44];I2=0%). Patients treated with EBL required fewer blood transfusions (mean difference [MD], 1.49; 95% CI [0.28, 2.71]; I2=96%) andhospitalizations (MD, 0.29; 95% CI [0.19, 0.39]; I2=0%). The number of sessions required for the obliteration of lesions was higherwith APC. There was no difference in the incidence of adverse events. Conclusions: EBL is superior to APC in the treatment of GAVE in terms of endoscopic eradication rates, recurrence of bleeding, andtransfusion requirements.
