In this study, a numerical approach based on mid-point integrated finite elements and a viscous boundary is proposed for time-domain wave-propagation analyses in infinite poroelastic media. The proposed approach is accurate, efficient, and easy to implement in time-domain analyses. In the approach, an infinite domain is truncated at some distance. The truncated domain is represented by mid-point integrated finite elements with real element-lengths and a viscous boundary is attached to the end of the domain. Given that the dynamic behaviors of the proposed model can be expressed in terms of mass, damping, and stiffness matrices only, it can be implemented easily in the displacement-based finite-element formulation. No convolutional operations are required for time-domain calculations because the coefficient matrices are constant. The proposed numerical approach is applied to typical wave-propagation and soil-structure interaction problems. The model is verified to produce accurate and stable results. It is demonstrated that the numerical approach can be applied successfully to nonlinear soil-structure interaction problems.

The objective of this study was to identify the proteins actively involved in the protection and repair of damaged cells, secreted by canine adipose derived mesenchymal stem cells (AT-MSCs) into the conditioned media. For this purpose, conditioned media (CM) was recovered from passage three stage canine AT-MSCs and skin fibroblasts cultured in serum free media after 24, 48 and 72 h. The extraction of exosomes was performed from 10-20 ml of CM using total exosome isolation kit. The isolated exosomes were then subjected to western analysis for the identification of annexin-I, annexin-II, histone H3 and dysferlin proteins. Results demonstrated the expression of proteins in the conditioned media isolated from canine AT-MSCs reflecting their potential in reducing the extent of damage at cellular levels. In conclusion, the conditioned media derived from canine AT-MSCs can be helpful in restoring the normal structure of cells both in vivo and in vitro conditions.

The study aims to investigate the effects of media and self-image congruity of ideal body image on the dieting and exercising behaviors of Korean and U.S. female college students. This study focuses on the concept of self-image congruity in order to examine how respondents perceive actual and desired self-images compared to an ideal female body image selected by respondents. A self-administered survey was conducted, resulting in 331 total responses (194 from Korean students and 137 from U.S. students). The data were analyzed through descriptive analysis, t-test, exploratory factor analysis, and regression analysis using SPSS 23.0. The findings revealed significant differences between Korean and U.S. female college students. U.S. students were more exposed to body image ideals in the media than Korean students; however, Korean female students valued the information regarding ideal body image conveyed by the media more than U.S. respondents. Among Korean female students, exposure to media messages regarding ideal body image and media importance had significant effects on desired self-image congruity, while these factors were not significant among U.S. students. However, there was a negative effect of media exposure on actual self-image congruity among U.S. respondents only. Additionally, the study uncovered that Korean students manage their body image through dieting behaviors while U.S. respondents manage body image through exercise behaviors (weight training as well as cardiovascular exercise). The study provides further support for self-image congruity, which extends its applications to the body image field.

This study analyzed and discussed the competition relation between various media platforms, particularly fashion magazine, the Internet portal, and social networking (SNS) that provide fashion contents. The following results were obtained through this study. First, the Internet portal ranks the highest in all factors, followed by SNS, and fashion magazine as the lowest. Second, the Internet portal was competing with fashion magazine and SNS because there is an overlap between the two platforms. By contrast, SNS has a relatively low degree of overlap with fashion magazines, and they are complementary to each other. Third, the Internet portal has a strong advantage over fashion magazine and SNS in all factors. On the basis of the results of this study, we can summarize remarkable points in strategy formulation as follows. First, the Internet portal, which is popularized by “usage accessibility,” is expected to continue to dominate the competition over other media platforms while providing greater gratification to users of fashion contents. Second, the competitiveness of fashion magazines, which has been shrinking dramatically, lies in the diversity and quality of fashion contents. Innovating ways to develop creative fashion content and improve the quality through more in-depth analysis of the reader is essential. Third, SNS is slightly behind the Internet portal as a whole; however, it is one of the emerging platforms in the fashion content market because of its competitive advantage in terms of gratification opportunities.

The physical and chemical properties of corrugated cardboard-based media were evaluated to assess their suitability as substrates for plants. Samples were collected periodically from the same study area over 5 months to determine any seasonal variabilities. In addition to the corrugated cardboard-based media, the rural soil of the study area was used as the control. The corrugated cardboard-based media showed adequate levels of moisture content and bulk density and correspondingly high porosity values when compared with the rural soil. All corrugated cardboard-based media showed adequate levels of electrical conductivity, organic matter, and correspondingly high cation exchange capacity values when compared with the rural soil in all seasons. The C/N ratio of the corrugated cardboard-based media was similar to the optimal values of 15-20. However, the pH values of the corrugated cardboard-based media were lower than the optimum value(pH 4) for plant growth and rural soil. The moisture content value which cycle bobs up and down according to sampling date, and this means that the moisture content is affected by seasonal changes in the components entering the study area. The corrugated cardboard-based media appear to be acceptable for growing plants(Lotus corniculatus var. japonicus). Finally, the use of this media permits better vegetation establishment than the use of rural soil. Our results prove that corrugated cardboard-based media can exhibit higher plant cover over a long period(September-November) as opposed to rural soil. Our study demonstrates the effectiveness of corrugated cardboard-based media for plant growth, and we recommend that future studies should focus on potential materials relevant to revegetation and management.

Destruxins (Dtxs) are insecticidal cyclic hexadepsipeptides produced by the entomopathogenic fungus Metarhizium anisopliae. Media composition for dtxs production was optimized with industrial grade media. Glycerol and casein peptone were selected as a carbon source and a nitrogen source, respectively. Dtxs production varied with C/N ratios. High yields of dtxs were observed at C/N ratios ranging 0.3 to 1.5, with concentrations mostly higher than 800 mg/L. Low yields were caused by high C/N ratio ranging from 3.0 to 8.0, resulting in less than 500 mg/L. The highest yield of Dtxs was obtained with 2% glycerol and 3% casein peptone, showing 192.2 mg/L of dtx A, 911.1 mg/L of dtx B, and 113.3 mg/L of dtx E, respectively. These results indicated that dtxs production is highly influenced by C/N ratio, especially the content of nitrogen source.

실 산성 도금폐수를 입상활성탄(GAC)이 유동메디아로 첨가된 유동상 멤브레인 반응기를 이용하여 처리하였다. GAC 유동조건에서 적용 투과플럭스에 대해 시간에 따른 흡입압의 증가는 관찰되지 않았다. 폐수의 중성 pH에서 파울링 속도는 산성 조건에 비해 GAC 유동조건에서 크게 감소하였다. 해당 폐수의 용액 pH 증가는 입자크기의 증가를 가져왔고 이는 멤브레인 표면에서 상대적으로 성긴 구조의 케이크층 형성을 야기시켰다. 유동상 멤브레인 반응기에서 GAC 유동 하에 95% 이상의 COD 제거율이 관찰되었으며 총부유물질은 거의 완벽하게 제거되었다. 실 도금폐수의 pH에서, 유동상 멤브레인 반응기의 구리 및 크롬의 제거는 거의 관찰 되지 않았다. 그러나 pH를 중성으로 증가 시켰을 시 구리와 크롬의 제거율은 각각 99%와 94%까지 증가를 하였다. 적용해 준 pH에 상관 없이, 시안의 경우 95% 이상의 제거율을 달성하였다. 이는 유기물과 시안 착물 형성으로 인해 유동상 멤브레인 반응기 내 GAC의 강한 흡착으로 제거된 것으로 사료된다.

Introduction The fashion business is known as one of the major industries that is suffering from rising concerns about the consumption of its product, which led to a reorganization of the fashion supply chain to become more sustainable three decades ago. The interest in the concept of sustainability and demand for sustainable marketing activities is gradually growing in the fashion industry due to the negative image and press it receives. Within the luxury fashion segment, the three main themes that are recognized to contribute to sustainability are exclusivity, craftmanship and limited production. However, luxury brands are increasingly shifting their attention and commitment towards environmental and social issues to be incorporated in the concept of sustainability. Yet, the majority of consumers has little understanding or misunderstands the concept of sustainable fashion and marketing, which leads to a gap between attitudes towards sustainability and actual behavior. As a result, fashion brands are trying to leverage their brand by making sustainability a key marketing strategy to raise awareness about social, environmental, economic and cultural issues. Extant research has not explored this recent trend to understand how consumers evaluate fashion brands with a sustainable marketing communication, especially in the context of luxury brands. This study investigates how luxury and mass fashion brands can utilize sustainable marketing contents in social media communication to reach their target group and enhance their equity with sustainability associations. Theoretical Development Associative network models of memory have served as a fundamental framework for a wide range of studies related to the formation and transfer of associations. According to associative network theory, brand knowledge is represented in form of an associative network of memory nodes connected to each other. Nodes are activated when cues, such as advertising, are presented. Mere exposure to cues was shown to be sufficient to active associations and facilitate association transfer. While brands are continuously attempting to make use of associative power to leverage brand equity, extant research has provided compelling reasons to accept that association transfer can also result in brand dilution when a retrieval of conflicting or negative associations occurs. Especially in the context of luxury brands consisting of very unique associations and being different from mass brands in many regards, managing the brand’s associative network is a crucial task in order to send the right signals to consumers and maintain exclusivity. This study investigates how social media communication of different sustainability dimensions affects brand attitude and how it ultimately impacts behavioral outcomes in an attempt to build brand equity for mass and luxury fashion brands. Method and Data The hypotheses are tested with 273 respondents who participated in an online experiment. They were first asked to state their involvement with the category fashion. Subsequently, subjects were presented with a brand post either for the mass or luxury brand including claims related to one of the four sustainability dimensions or no claims for the control group respectively. The experiment consisted of a 2 (brand: mass or luxury) x 5 (sustainability dimensions: none, cultural, economic, environmental, social) factorial design. The measures that followed included attitudinal as well as behavioral constructs related to the brand, sustainability as well as social media use. Analysis of covariance is applied to test for main effects and interaction effects. Summary of Findings This study provides evidence that social media communication of a sustainable brand affects the purchase intention of consumers. The findings indicate a significant difference between the mass and the luxury brand used for this study. The mass brand exhibits the potential to leverage associations with cultural, economic, and environmental sustainability. However, the results only reveal a marginally significant higher purchase intention when cultural sustainability is communicated compared to when the brand does not provide any sustainable associations. In contrast, the luxury brand suffers from significant brand dilution across all four sustainability dimensions resulting in a decline in purchase intention. Key Contributions The findings reveal that sustainability communication exerts a diverging influence depending on the type of brand that is involved. This study suggests that mass brands are able to benefit from sustainability communication in an attempt to leverage brand equity. However, for a luxury brand this type of associations rather presents a liability that might dilute the brand. The findings of this study provide important insights for brand managers. Since mass brands are currently increasing efforts into sustainable communication in the fashion industry, the results suggest that this might be a promising investment. However, luxury brands are advised to carefully manage the communication of salient content related to sustainability as it might harm the invaluable and unique associations inherent in a luxury brand.

Corporate reputation – the central antecedent of trust – bears the potential to create sustainable competitive advantage. However, far too many examples of companies’ socially irresponsible behavior over the past years led to a severe crisis of confidence. Disgraced companies suffer from the adverse effects of their misbehaviors at all levels. As a consequence, one of the top priorities for both practitioners and business scholars is the identification of opportunities to (re)build corporate reputation. Corporate Social Responsibility (CSR), a key driver of reputation perceptions, is a very promising one. However, as CSR is a multidimensional construct that comprises a wide range of activities, the selection of the “right” ones deems a major challenge. Based on a literature review, we advocate that news media data should be utilized to analyze which CSR dimensions are particularly likely to affect reputation perceptions. As journalists rely on companies’ press releases as a starting point for their business articles, companies need to carefully evaluate which CSR dimensions they emphasize in their communication strategy. Based on superior measures of reputation and CSR, this study utilizes reputation and news media coverage data on companies listed in the German DAX30 between 2005 and 2011. The panel data regression encompasses the multidimensional concept of CSR, presenting a six-dimensional CSR construct including environment, employee relations, community, product issues, corporate culture and corporate governance. Relevant moderating variables, namely firm and stakeholder characteristics, are investigated. In this context, the results show that the relevance of each of those six distinct dimensions differs for the formation of reputation judgements and varies across investigated stakeholder and company types: across all model specifications, negative media coverage addressing employee relations and community affects reputation perceptions. The general public primarily perceives negative news coverage as relevant for their reputation judgements. Opinion leaders seem to be less dependent on the media to learn about CSR dimensions, as only four out of twelve independent variables exert a significant impact on their reputation judgments. News coverage about product issues only constitutes a key role in the formation of reputation judgements of firms that are predominantly known from direct experiences. A particularly large amount of variation can be explained for reputation ratings of these companies as well as for reputation perceptions of opinion leaders.

The literature suggests that the adoption and use of social media can derive a number of benefits to B2B firms (see Siamagka et al, 2015; Wang et al, 2016). Despite the benefits however, the adoption and use of social media in B2B setting is slow (Lacka and Chong, 2016), so is research examining social media adoption by B2B firms (Iankova et al, 2018). To date, only a handful of studies explored factors driving social media use for B2B marketing purposes (Siamagka et al, 2015; Lacka and Chong, 2016). Lacka and Chong (2016), for example, revealed that practical acceptability (perceived usefulness, usability and utility) drives adoption decision. They ignored however the role of social acceptability, referred to social factors, which according to Nielsen (1993) is crucial in the technology adoption decision. Social factors are conceptualised as subjective norms or group norms, which motive persuasion of specific behaviour (e.g. technology use). The importance of assessing social acceptability has been most recently highlighted by Brink (2017), who recognises the key role of leadership from senior managers in the adoption and use of social media by B2B firms. Empirical research is however yet to verify such an impact. In addition to limited research on B2B social media adoption, there is lack of research on the role culture plays in the adoption decision. Previous research has showed hat culture impacts adoption of social media and its use (e.g. Hsu et al, 2015). Yet, there is lack of research on the impact of culture on the social media adoption in B2B setting. This study aims to address this research gap. Specifically, in line with this conference call this study aims to examine the impact of Chinese culture on social media adoption by B2B marketing professionals. This will be achieved though exploratory quantitative study.

There is scarcity of studies on social media strategy, and their appropriate implementation, applied to the case multinational corporations. In particular; there is a lack of studies adopting a cross-cultural approach (Okazaki and Taylor, 2013). Behind this fact is the assumption that, in general, multinational corporations adopt a global strategy that does not fit well with the personalized nature of social media. From the perspective of social media management, there are a kind of dilemma between the adoption of a centralized and standardized content generation and diffusion approach vis á vis adopting a decentralization orientation at country level or even a more local level. Berthon, Pitt, Plangger, and Shapiro (2012) signal the challenge of standardizing corporate content in social media and point out the advantage of take into consideration the specificities of different cultures and countries. We found a tension between two trends, for one hand social media implies co-creation and the sharing the power between the firm and their customer, while global integrated marketing communications follow precisely the opposite route. This research was conducted to examine the influence of centralization degree of social media communication towards online customer. We develop an empirical study applied to more than 160 corporate Twitter accounts from Iberoamerican countries. These accounts are the universe of Spanish corporates accounts of a set of the most important global automobile brands over a two-month study period. We use post-level engagement metric as measure of consumers’ attitudinal responses to corporate tweets. The results indicate that online customer engagement is affected by the type of the social media account of the brand (global, country, distributor, event specific). A strategy of issuing tweets from more general and global account result in a greater impact on customer engagement. In general, it seems that a centralized strategy obtains more effect in the number of obtained retweets even controlling by content topic, sender and post characteristic. This research has important implications for Digital Managers of corporations in terms of better understanding and improving corporates’ strategy in the social media communication channels.

Hospitality and tourism industries have recognized that engaging with customers via social media is now a critical element of their marketing strategy. Given the high variability of success with which firms have been attracting customer interest online, businesses are clearly struggling to determine exactly the right methods to use the newest technologies. This study presents a predictive model of attributes for online posts that evoke a high level of customer engagement. The contribution to the literature is a unique set of features that have significant impact on customer engagement, using a big-data set to support findings. In accordance with theories originating from Social Belongingness and Brand Community Marketing, findings indicate that appeals to a sense of community belonging have a significant impact on customer engagement in social media. Specifically, communities have idiomatic vocabularies consisting of “activation words” that are especially effective for engaging customers on social media. This has both theoretical implications in that it constitutes a large-scale, real-world confirmation of belongingness hypotheses, and managerial implications in that it suggests best practices for maintaining an online presence.

As Internet use has increased, customers have become more active at sharing their travel opinions through social media regarding their experiences with service organizations. Social media has become a ubiquitous tool that enables customers to share their travel experiences. In particular, members of Generation Y are more likely to be active on social media and more likely to share their experiences online. Understanding Generation Y’s online customer engagement preferences on different social media platforms may help to enhance brand loyalty. Customer engagement (CE) has been attracting the attention of both practitioners and academics because it may help to enhance both brand loyalty and purchase decisions. Social media platforms have become a significant communication tool for both customers and service providers, creating an opportunity to engage with customers. Interacting with active customers on the right social media platform can increase direct bookings, building brand loyalty. Therefore, the purpose of this research is to examine Generation Y’s brand loyalty preferences through its members’ engagement with social media. The results of this research will expand understanding of Generation Y customers’ online engagement through social media. This research may also suggest how hotels are able to utilize social media platforms in order to encourage online engagement with Generation Y by building brand loyalty.

This conceptual paper drew on the uses and gratifications theory to theorize about what drives consumers to engage in social media activation campaigns. This paper proposed that satisfying the needs for integration and social interaction, personal identity, information seeking, entertainment, and utilitarian reward through a social media activation campaign can enhance consumers‘ engagement with it. Finally the way in which cognitive, affective, and behavioral engagement with such campaigns affect brand image was explained theoretically. The developed conceptual framework can help marketing managers to create engaging social media activation campaigns, thereby improving the image of their brands.
