This study examined the antecedents and outcomes of leader-member exchange (LMX) quality in the Korean Army platoons. Although a number of studies have devoted substantial attention to the application of the LMX theory in various organizational settings, there has been no effort to verify or to apply the model to a military situation. In this paper, we tried to build an integrative LMX model to apply to the Korean army. We developed, on the basis of literature review, an integrative framework describing the factors affecting the LMX quality, LMX quality outcomes and the moderators of LMX quality-outcomes. Then we collected data from the 404 lieutenant-soldier dyads. The analysis of the data showed that 1) interpersonal variables (perceived similarity and liking of soldier) and LMX quality were significantly related, 2) LMX quality and outcome variables(soldier's performance, job satisfaction, and morale) were significantly related, and 3) the relationship between LMX quality and soldier's performance were strongly significant when task challenge is high but nonsignificant when task challenge is low, while there were nonsignificant or weekly significant relationships between LMX quality and soldier's performance when task challenge is moderate. The results are basically coinciding with the previous research, except that, with the low challenge tasks, the LMX quality did not affect soldier's performance, which seems to be due to the directive leadership style of the lieutenants. The theoretical and practical implications and future research directions are discussed.

Purpose: The results of prior studies investigating main effects between diversity and team performance are neither clear nor consistent. This study seeks to provide more evidence for a direct link between these two. The present study also attempts to close a gap in the literature by examining conflict as a moderator of the relationship between diversity and team performance. Methods: As suggested by Williams and O'Reilly(1998), this study examines the effects of perception levels of three specific types of diversity (social category diversity, value diversity, and informational diversity) and two contextual moderators (task conflict and relationship conflict) on team performance. Results: The results show that perception levels of all three types of diversity are significantly related to team performance in the current sample of 313. Results also indicate that relationship conflict significantly interacted with the perception levels of diversity in relating to team performance. Results for task conflict, however, fails to support the hypothesis. Conclusion: The results suggest that the effects of diversity on team functioning depend on how diversity is perceived by team members, rather than actual diversity seen by team members. Theoretical and practical implications are reviewed, and limitations of the study and suggestions for future research are addressed.

The study tested a hybrid model with constructs drawn from the Technology Acceptance Model (TAM) and Diffusion of Innovation (DOI) theory in order to examine the moderating effect of productivity and relative advantage (RA) on perceived usefulness (PU) vis-à-vis electronic information resources (EIR) adoption in private university libraries in Ogun and Osun States of Nigeria. The descriptive research design was adopted in the study. The population consisted of 61 (55.0%) librarians and 50 (45.0%) library officers (totaling 116—100%) in Babcock University, Bells University, Covenant University, Bowen University, Oduduwa University, and Redeemer's University. Purposive sampling procedure was adopted after which total enumeration was used since the total population is small. The questionnaire was used for data collection. Of the 116 copies of the questionnaire administered, 111 (95.7%) were found usable. The instrument was structured based on a 4-point Likert agreement scale of Strongly Agree, Agree, Disagree, and Strongly Disagree. Data were analyzed using descriptive statistics like tables of frequency counts and percentage. The findings revealed that productivity and relative advantage are significant moderators of perceived usefulness of EIR adoption in private university libraries in Ogun and Osun States, Nigeria.

Purpose Online platform companies can increase the spread of content by communicating with users who have diverse preferences through social networks. Previous studies show the mixed effect on the network overlap, and there was a limited examinations for the underlying mechanism. This study expects high academic and practical implications that can be provided by studying on the user's viewership network. The purpose of this research is to examine the effects of network overlap on the users' viewership for creators of user-generated content in YouTube. We explain the direct and in-direct effects through the content sharing and the valence of user ratings. Design/methodology/approach The data contains 45 channels and 4,085 video clips from YouTube. We control the effect of the categories, channel characteristics, and vide clip characteristics on the viewership. PROCESS macro were used to analyze the direct and in-direct effects of network overlap. Findings The analysis results showed that the network overlap directly affect on the users' viewership. The variable decreases the moderators (i.e., content sharing and the valence of user ratings). This result implies that the users can not satisfy their need for uniqueness which is achieved by content sharing and rating in the overlapped network.

본 연구의 목적은 기술스트레스에 관련된 기존의 연구에서 인구통계학적 측면에서 나이와 성별에 대한 개인간 차이가 발생하는지 살펴보고자 수행되었다. 기술스트레스에 대한 개인의 반응은 이미 오랫동안 연구되어왔다. 하지만 변화하는 인구통계학적 패턴이 기존 연구에서 반영되지 않은 경우가 많았다. 특히 업무현장에서 정보기술은 개인별 특성에 의해 깊이 관련이 있기에 관련 연구가 필요하다. 연구 결과 기술스트레스의 구성 요인들은 나이와 성별에 따른 차이를 나타내는 것으로 확인되었다.

This study examines the relationship between perceived risk and regret, the influence of regret, and the regret-solution effort upon post-purchase behavior. These causal pathways are controlled by moderated different impulse buying types. The results of the study are three-fold. First, consumers with high social and convenience risks resulted in the high levels of regret. Second, the higher the regret then the higher the negative purchase intention and the lower the positive purchase intention. Consumers who emphasize the regret-solution have high positive purchase intentions and the low negative purchase intentions. Lastly, as for the influence of the regret upon the negative purchase intention, the 'recollection impulse buying type' has the greatest influence among all other types. No impulse buying types have a positive influence on purchase intention. As for the influence of the regret-solution efforts on the positive purchase intention, the 'pure impulse buying type' had the greatest influence. Only the 'suggestion impulse buying type' influenced the negative purchase behavior intention. The post-purchase intention depends on the level and the degree of the regret-solution efforts of the consumer. This study contributes to the examination of the different impulse buying types that influence the moderators in the causal pathway of the risk perception to the post-purchase buying behavior.

With the e-business paradigm emerging, the website became a critical resource for most corporations. However, the amount of value creation through internet is still in question. This paper shows the result of an exploratory study on website assessment, following the tradition of Technology Acceptance Model (TAM). We viewed the intended usage as the value of the website and added such factors as playfulness, commitment, system quality, and information security as external variables of the model. Website types, visiting purposes, and the user system quality were included as moderators. The website value could differ depending on website types, purposes of the use and system quality. In the case of internet shopping malls, playfulness, compatibility, website quality were identified as key influencers, while for stock trading users, however, commitment and security factors are more important. In terms of user purposes, information search requires both the compatibility and the website quality. Also the website quality was strongly affected by the user system quality. In other words, any investment of upgrading the website system quality can be meaningless unless the user system quality is improved as well. For each variable considered, empirical results are discussed and practical implications are provided.

Purpose - Underdog positioning is often used to evoke a positive attitude when interacting with consumers. However, little research has been conducted on the market competition structure and innovation contexts in which underdog positioning produces the most impact. This research aims to investigate unexplored boundary conditions of underdog positioning and addresses two issues: market structures (oligopoly vs monopolistic competition) and perceived firm innovativeness (PFI). Design/methodology - Two one-way ANOVA designs (market structures: monopolistic competitions vs. oligopoly; perceived frim innovativeness: strong vs. weak) were randomly assigned to 297 graduate and undergraduate students (52 % female) majoring in business. Study 1 examined the effect of underdog positioning on consumer attitudes in the different market structures. Study 2 investigated the relationship between underdog effect and consumer attitudes through viewing conditions that varied in PFI. Findings - Drawing on the results of the study, the authors conclude that underdog positioning is effective to generate more positive consumer attitudes when employed in the market structure of monopolistic competition rather than oligopoly. Moreover, both underdog and top dog positioning are likely to generate more positive consumer attitudes when accompanied with strong PFI than weak PFI. Originality/value -This is the first study to distinguish between monopolistic competition and oligopoly market structures with underdog positioning as well as to demonstrate a positive effect of PFI, regardless of the type of brand narratives.

Purpose - This exploratory study analyzes the performance of the business from the HRM point of view. Analyzed the influence of HRM and organization effectiveness on business performance. Also moderating effect of the strategy is analyzed. Research design, data, and methodology - Two outcome variables are measured, non-financial performance and financial performance. Two organizational effectiveness variables are measured, job satisfaction and organizational commitment. And two HRM areas are measured, HRM practice and organizational culture. Finally, two strategies are measured as moderators, market strategy and product/service strategy. This study analyzed employees of 554 from the 7th HCCP. This study used SEM and MCFA. Result - The results of turnover intention, growth rate, and profit rate verified the influence of HRM and organizational effectiveness. Overall results showed a contrary effect of education & training system implement and participation on job satisfaction and organizational commitment. Among organizational culture, innovation and relation positively affect job satisfaction and organizational commitment. However, antecedents influencing turnover intention, growth rate, and profit rate bear no resemblance. And the MCFA result shows that strategy's group differentiation analysis is meaningful in turnover intention not in financial performance. Conclusion - Based on this study result, management suggestions for turnover intention, growth rate, profit rate, and organizational effectiveness are made. Especially, due to the company's strategy.

The purpose of this study was to offer a new conceptual framework based on a combination of the TPB model, the TAM model, and two additional constructs consisting of eWOM and pricing value called the E-P-TAM-TPB model, and to assess the model's implications on hotel selection behavior. This study empirically examines the E-P-TAM-TPB model to evaluate and validate domestic tourists' online hotel booking intentions by using the partial least squares structural equation modeling (PLS-SEM) approach. The data was collected from 355 domestic tourists who booked the room via the hotel website. The major findings of this study indicated that the E-P-TAM-TPB model has a positive significant influence on online hotel selection behavior. The results revealed that all proposed hypotheses were declared supported. Future studies should build on the framework by incorporating potential moderators to better understand how different groups of customers behave online in different segments of the hospitality industry. Managers must not only develop an easy booking process but also provide price value information to attract or impress clients. Tourists can compare room rates with other hotel websites and OTAs.
