This study is intended to examine two issues related with social media messages. At first, the authors investigate that how they can categorize messages in the social media and how corporate twitters and brand twitters communicate with consumers. Secondly, after dividing messages in the social media into several groups, the authors investigate how each type of messages differ one another in terms of the consumer response. For examining these research issues, the authors gather twitter message data of global top 100 brands and categorize messages into 5 types (i.e., interactivity, diversion, information sharing, promotional, content) based on the motivation of communication and the format of the messages. Especially, the authors use content analysis methodology, which is normally used as the qualitative approach, in order to identify the type of messages. Furthermore, the authors present interactivity type of messages can communicate better with consumers and induce more favorable responses from consumers in the social media than any other type of messages. This research can provide implications in terms of theoretical, methodological, and managerial perspective.

The purpose of this study is to identify and comprehensively explain the SCM-related factors involved in the realization of RTE, including the quality of information concerning SCM, the quality of SCM partnerships, and relationship controlling factors (planning control, behavioral control, and outcome control). This study systematizes the interactions among these factors into a form of a model, elucidating how these interactions affect and shape RTE characteristics. To validate the research model proposed in the study, filed survey was conducted with 79 staffs in Korean company using SCM. The findings of the study can be summarized as follows: First, the quality of information concerning SCM had significant effect on the quality of SCM partnerships, planning control, behavioral control, and outcome control. Not only does the quality of SCM information directly influence the quality of SCM partnerships, planning control, behavioral control, and outcome control; but it also indirect influence on forecasting, agility, and visibility of SCM though its influence on the different forms of relationship control. Second, the quality of SCM partnerships also had significant effect on planning control, behavioral control, and outcome control. In addition to directly influencing these forms of relationship control, the quality of SCM partnerships also indirectly influenced forecasting, agility, and visibility though its influence on relationship control. Third, planning control significantly influenced forecasting, agility and visibility. Fourth, behavioral control significantly influenced forecasting, but neither agility nor visibility. Fifth, outcome control had significant influence on forecasting, agility, and visibility.

The introduction of smartphone caused the most revolutionary change in the domestic telecommunications market after the digital revolution. However, due to the saturation of the local market, it is expected to post negative growth in 2016 and the sales of national communication carriers is in stasis. Thus, the smartphone industry is starting to shift its marketing efforts to secure the silver generation who still has room for increase in the rate of smartphone usage. As the silver generation has physical limitations and differences in needs, the marketing strategy based on the smartphone utilization is not appropriate. This study suggests the new silver generation, who has high income level and similar characteristics to the younger generation, as the new customer segment for smartphone. We analyze the effects of the major variables of UTAUT on smartphone use, as well as examine how these relationships differ between the new silver and the net generation. We verified the hypotheses using a survey with 309 smartphone users. The research findings supported the hypotheses regarding the effects of performance expectancy, effort expectancy and facilitating conditions on smartphone use, but did not support the hypothesis on the effect of social influence. The result of the group comparisons showed that both generation have similar characteristics on innovativeness and cognitive absorption, but the moderating effect of age on performance expectancy, effort expectancy and use is stronger in conjunction with the new silver generation. The study results are expected to be used in establishing a marketing strategy for the new silver generation.

The effective supply chain management(SCM) is a matter of survival in many firms because successful supply chains will effectively coordinate their processes, focus on delivering customer value, eliminate unnecessary costs in key functional areas, and create performance measurement systems. The balanced scorecard(BSC) is widely used to measure the performance of the SCM. The BSC framework suggests that balance is obtained by adopting performance measures from four different areas. In this study, we analyzed the causal relationship of SCM performance based on BSC framework. First, we reviewed the nested causal relationships among four different perspective of the BSC, namely, business process perspective, customer perspective, financial perspective, and innovation and learning perspective. Then, we used the chi-square difference test to identify the best model to fit the causal relationship of SCM performance. Of the 800 questionnaires posted, a total of 265 questionnaires were returned after one follow-up. A total of 66 questionnaires were eliminated due to largely missing values. The major finding says alternative model 3 is dominant to other models to fit causal relationships among four different perspective of the BSC. Innovation and learning perspective positively influence on customer perspective, business process perspective, and financial perspective. Business process perspective also positively influence on customer perspective and financial perspective whereas customer perspective does not influence on financial perspective significantly.

How can business ecosystems be a source of firm`s competitiveness? Is corporate social responsibility (CSR) is an investment activity for building sustainable business ecosystems? The purpose of this research is to identify the relationship between CSR, social value, sustainable business ecosystems, and firm`s competitiveness by introducing a mediating role of social capital. We conducted in-depth interviews with seven informants from two domestic firms and four oversea firms. Three propositions were drawn by analyzing qualitative data collected from the interviews and literature review. Various activities creating social value including CSR and CSV (Creating Shared Value) are positively associated with sustainable business ecosystems. Firm accumulates social capital of the business ecosystem through creation of social value. Finally, the social capital of business ecosystem has a positive influence on firm`s competitiveness. Implications were suggested for academics and practitioners.

Under the premise that information privacy concerns can atrophy e-commerce by causing particular behaviors of Internet users, this study focused on exploring the causes of information privacy concerns, the related information privacy protective responses of Internet users, and measures for alleviating the information privacy concerns. This study is based on the `principal-agent theory,` and established the following as factors that cause information privacy concerns of Internet users: perceived information non-transparency; perceived action uncertainty. Also, the information privacy concerns caused by the factors were established as the cause of information privacy protective responses of Internet users. Also, the concept of `signaling` and `incentive,` which were presented to solve the adverse selection and moral hazard issue in the host-agent theory, was introduced to establish the following as factors that alleviate information privacy concerns: trust; informativeness. Those factors were included in the research model to conduct an empirical analysis. The analysis has revealed that both the perceived information non-transparency (p<0.01) and perceived action uncertainty (p<0.01) as to websites had a significant impact on information privacy concerns. Also, information privacy concerns of Internet users (p<0.01) had a significant impact on their information privacy protective responses who strive to protect their personal information. In addition, when trust and informativeness, which were established as factors that can alleviate information privacy concerns, were empirically analyzed, trust and informativeness had the effect of alleviating information privacy concerns. Based on the findings, the following was confirmed: Boosting the trust of Internet users in websites and offering useful information related to personal data can play a key role in alleviating the information privacy concerns of Internet users.

Consumer`s switching behavior from incumbent smartphone to new one can be explained by not merely rational assessment but also affective aspects like aesthetic or pleasure and emotional points like attachment. but, in information system field, researches on affective.emotional factors relatively were insufficient and researches which focus on the perspective of the consumer were more scarcity. consumer`s attachment to current smartphone brand and perceived aesthetic on new one would influence rational evaluation to switch or not. Therefore, this study investigates relationship between emotional factors on current smartphone and assessment of new one, in turn, we empirically analyzes purchase intention of the consumer. In order to prove the validity of the hypotheses, this study was applied longitudinal study and then conduct a survey of 212 smartphone users. The analysis results by Partial Least Square (PLS) approach showed that all hypotheses in this study were statistically supported.
Effects of ICT Device Ownership on Consumers` Digital Piracy Behavior
Sim, Hyeonbo ; Kim, Minki ; Moon, Junghoon ;
The Journal of Information Systems, volume 23, issue 4, 2014, Pages 169~196

This study investigates how information and communication technology (ICT) can damage intellectual property rights (IPR) in the movie industry. Utilizing a survey questionnaire to gather information about the extensive use of ICT devices, including tablet PCs and smartphones, we demonstrate how digital piracy behavior is associated with various socio-demographic characteristics. Econometrically, since a large number of people do not engage in piracy activities, we adopt a zero-inflated negative binomial model. We find that people with tablet PCs are more likely to engage in the piracy of movies from peer-to-peer (P2P) sites. In particular, when we categorize ICT devices based on whether they are portable and allow downloads, we find that people with devices equipped with both functions are most likely to engage in movie piracy.

Despite of continuous efforts to crack down on piracy using penalties and regulations, this unauthorized piracy market is still enormous. Since the moral hazard about this phenomenon is pervasive and continually upsets the major intellectual property markets, an alternative plan is required. The purpose of this study is to provide an objective insight for factors that affect people`s digital video piracy behavior. The following two research propositions were the focus: what psychological factors affect piracy behavior and how are these factors related to one another? In order to accomplish the research aims, we reviewed literatures on the current state of piracy in South Korea, characteristics of digital contents, studies on criminal psychology and behavioral theories. Previous research in the fields of criminal theory indicated that neutralization, a form of rationalization, would help explain digital piracy intentions. Thus, this study developed a model that explains effects of neutralization techniques and tested the possibility of an integrated model with other behavioral theory such as TPB and TIB. Empirical results of the study(368 sample collected) showed that all the factors in TPB including Attitude to Piracy(+), Subjective Norm(-), Perceived Behavioral Control(+) had a significant impact on Piracy Intention. Moreover, two neutralization techniques, Condemn the Condemners(+) and Appeal to Higher Loyalties(+), had a significant effect on Piracy Intention. In addition, Past Behavior had strong impacts on Attitude(+), Perceived Behavioral Control(+) and Piracy Intention(+). In terms of Expected Profit, it had an impact on Attitude to Piracy positively. These findings suggest implications for protecting the current intellectual property markets, with many stakeholders in movies and media industries. There are some limitations as followed: first, the study did not consider other neutralization techniques, low level of deterrence and the other expected results despite the possibility of their effects. Second, the study needs improvements through longitudinal research because the cross-sectional research could not rule out the alternative explanations.
