Prior studies on the effects of online consumer reviews have mainly focused on review valence, but little research has investigated how two-sided (both positive and negative) and one-sided (only positive) reviews influence consumers' response to online review. In addition, little attention has been paid to how sponsorship presence (firm-sponsored reviews vs. consumer-voluntary reviews) influences individuals' attitude toward online review. Unlike consumer-voluntary reviews without any monetary incentive, firm-sponsored reviews include messages about brands providing monetary compensation. This study examines whether review valence (two-sidedness vs. one-sidedness) influences attitude toward online review via its influence on review credibility. Further, this study examines whether sponsorship presence affects when review valence influences attitude toward review. Thus, this research investigates the effect of review valence on attitude toward review and the moderating role of sponsorship presence in the relationship between review valence and attitude toward review. The first experiment reveals that attitude toward review is more favorable when the review is two-sided (vs. one-sided). The second study demonstrates that differences between the two-sided and the one-sided review occur only for firm-sponsored reviews, not for consumer-voluntary reviews. The theoretical and practical implications are also discussed.

This study conducted a comparative analysis of awareness level of review standards, continuing education, and awareness about the need for speciality and educational courses in order to improve quality of Korean health insurance review work and to present directions for policies of personnel development and continuing education to smoothly perform hospital's insurance claim work and Agency's review work. The analysis unit of the study is individuals, and survey was conducted among hospital's claim officers and Agency' review officers by distributing questionnaires. The major results of the study are as follows: First, it is found that hospital's claim officers and Agency's review officers have conflicting awareness about review standards; more Agency's review officers think that current review standards are universal and reasonable, while more hospital's claim officers believe that they need to be revised. Especially, hospital's claim officers replied that it is possible that review results can differ according to government's policies. Second, there is no significant difference between the two groups in the opinion that there are individual differences in awareness level of review standard. In particular, both groups share the opinion that review results can differ according to officer's interpretation of review standards. Third, Both review officer groups feel the need for further training and continuing education. Fourth, there is no difference between the two groups in the opinion that both groups members should be educated in review related educational institutions. However, while 81.5% of Agency's review officers the education should be offered at the Agency, only 45.2% of hospital's claim officers agreed to it. Fifth, both review personnel do not show any difference in awareness of needed experience to successfully perform review work; both groups replied that three to four years experience is necessary to smoothly perform claim work and review work. This study was tried in order to search for directions to improve Korean insurance review work in quality rather than to explore characteristics themselves of individual factors. In this sense, this study presupposed an intention that the educational subjects for further training and continuing education for the two groups should be the same in order to narrow the awareness gap between hospital's claim officers and Agency's review officers. Thus, this study suggests that it is desirable to offer beginner courses at junior colleges or in undergraduate courses and advanced courses in professional graduate school for six to twelve months. In that a comparison of awareness level of hospital's claim officers and Agency's review officers who are actually in practice should precede appropriate presentation of directions for the qualitative improvement of insurance review work in Korea, the significance of this study lies in comparatively analyzing the awareness level of hospital's claim officers and Agency's review officers and in presenting the establishment of future further training and continuing education.

An institutional review board (IRB) should independently safeguard the right, safety, and well-being of all clinical trial subjects. It should consist of members who are qualified and experienced to review and evaluate the science, medical aspects, and ethics of the proposed trial. They have to pursue continuing efforts to improve the standards of review. The levels of review include the full board review, expedited review, continuing review, or exempt from review, while the levels of decision-making include approval, conditional approval, deferred approval, and disapproval. Investigators must follow the approved protocols and regulations honestly, and it is the IRB's mission to audit clinical trial sites as well.

Purpose - Online product review has become a crucial part of the online retailer's market performance for a wide range of products. This research aims to investigate how an individual reviewer's review frequency and timing affect her/his average attitude toward products. Research design, data, and methodology - To conduct reviewer-level analysis, this study uses 42,172 posted online review messages generated by 6,941 identified reviewers for 59 movies released in the South Korea from July 2015 to December 2015. This study adopts Tobit model specification to take into account the censored nature and the selection bias arising from the nature of J-shaped distribution of movie rating. Results - Our estimation results support that the negative impact of review frequency and timing on valence. Furthermore, review timing has an inverted-U relationship with the user's average valence and enhance the negative effect of review frequency. Conclusions - This study contributes to the growing literature on the understanding how eWOM is generated at the individual consumer level. On the basis of the main empirical findings, this study provides insights into building a recommendation system in online retail store based on the consumer's review history data - frequency, timing, and valence.

The purpose of this study is to explore the effect of different types of simultaneous presentation (i.e., reviewer information, textual and visual content, and similarity between textual-visual contents) on review usefulness and review enjoyment in online restaurant reviews (ORRs), as they are interrelated yet have rarely been examined together in previous research. By using Latent Dirichlet Allocation (LDA) topic modeling and state-of-the-art machine learning (ML) methodologies, we found that review readability in textual content and salient objects in images in visual content have a significant impact on both review usefulness and review enjoyment. Moreover, similarity between textual-visual contents was found to be a major factor in determining review usefulness but not review enjoyment. As for reviewer information, reputation, expertise, and location of residence, these were found to be significantly related to review enjoyment. This study contributes to the body of knowledge on ORRs and provides valuable implications for general users and managers in the hospitality and tourism industries.
