Abstract
Purpose
This study is based on the heuristic-systematic model (HSM) to dynamically examine the effect of review variance on sales and the boundary conditions that mitigate this effect.
Design/methodology/approach
Based on the theoretical domain of HSM, a conceptual model is proposed that analyzes the nonlinear relationship between review variance and sales and the interaction and motivation factors that moderate these relationships. Review data from websites targeting the film industry in the USA and South Korea (Korea) were collected to empirically analyze the authors' hypothesis, and panel regression analysis was used for confirmation.
Findings
Moderated by interactive and motivational factors, review variance exhibits an inverse-U-shaped relationship with review variance. Specifically, as an interaction factor, review valence and owned social media (OSM) resulted in positive interaction effects, and as a motivation factor, the number of alternatives exhibited a positive interaction effect with review variance. The effect of review variance was less pronounced in the USA than in Korea.
Originality/value
The study outcomes reveal a nonlinear relationship between review variance and sales, thus supporting the contradictory findings of previous studies. This study contributes to the literature by using the HSM as a theoretical framework to verify various HSM mechanisms using online review data. This exploratory study also contributes to the international marketing literature by showing that the effects of review variance vary across cultures.

Abstract
Purpose
The authors investigated the effects of the characteristics of reviews, reviewers and corporate factors on review helpfulness and assessed the role of culture in moderating these relationships.
Design/methodology/approach
A research model was established based on the elaboration likelihood and information adoption models. To empirically analyze this research model, 10,611 TripAdvisor reviews from 9 countries were collected. In addition, a zero-inflated negative binomial model and multilevel analysis were employed in consideration of the data characteristics.
Findings
The results revealed that review depth had a positive effect on review helpfulness, and review ratings and reviewer expertise had a negative effect. As a corporate characteristic, hotel size had a negative effect on review helpfulness. In addition, the effects of review rating, reviewer expertise and hotel rating exhibited significant differences based on the moderating effects of uncertainty avoidance and power distance level.
Originality/value
The results of this study expand the review helpfulness literature by explaining the inconsistent findings of previous studies via cultural theory. In addition, past research in this field has mainly focused on analyzing only review and reviewer characteristics, while this study demonstrated that company size negatively affects review helpfulness based on the signaling theory. Finally, this study contributes to cultural comparison literature by discovering that the processing of review information by consumers differs according to their cultural background.

Abstract
Purpose
This study analyzes the relationship between the characteristics of social media content, customer engagement (CE) and brand equity and investigates whether these relationships differ between national cultures.
Design/methodology/approach
We collect data from a variety of sources, including Interbrand, Facebook and financial statements, to validate the research model using partial least squares structural equation modeling.
Findings
The results revealed that owned media content had a stronger positive effect on CE than did earned media content. In addition, information richness was found to have a positive effect on CE, but links to additional information had a negative effect. In addition, CE positively affected brand equity. The national comparison analysis revealed a difference in the coefficients between the United States and Korea for most paths.
Research limitations/implications
This study contributes to the relevant literature by finding evidence that OM has a stronger effect on CE than does EM. In addition, this study expands the related literature by clarifying the effects of information richness in a CE context and exploring differences determined by cultural dimensions. Most importantly, this study expands CE and international marketing literature by finding that the relationship between CE determinants and outcomes in a social media environment differs between national cultures.
Originality/value
This study explores the relationship between CE and social media content, which has not been sufficiently investigated in previous studies, by collecting actual social media data. In addition, unlike previous survey-based studies, we find evidence that CE contributes to brand equity at a corporate level. Finally, our exploratory analysis indicates that the relationship between the characteristics of social media content, CE and brand equity differs between national cultures.

Abstract
Purpose
The purpose of this paper is to analyze the relationship between customer engagement in social media (CESM), brand equity and corporate performance and investigated whether these relationships differed according to cultural factors in the United States and South Korea.
Design/methodology/approach
We collected customer engagement on social media data on Facebook and brand equity data from Interbrand for listed companies in the United States and Korea. A total of 405 data sets were analyzed by partial least squares structural equation modeling (PLS-SEM).
Findings
Results revealed that CESM did not affect financial performance through a direct path but was found to have a positive indirect path via the mediation of brand equity. In addition, this relationship was found to differ between the United States and South Korea.
Originality/value
This study contributed to the literature on social media and international management by verifying the relationship between CESM, brand equity and financial performance, and by presenting exploratory research results to ascertain if these relationships differ according to the cultural dimension of the country.

Abstract
Purpose
Drawing on the shopping goal theory, this study sets the following research questions. Research question 1: How do keyword characteristics of e-commerce platforms affect seller performance? Research question 2: Do these effects differ according to product type (utilitarian vs hedonic)?
Design/methodology/approach
Empirical analysis was conducted using a dataset of 24,907 keywords collected from 30 product categories on Amazon. Multi-level modeling was used to distinguish between product level and keyword level.
Findings
Regression analysis showed that keyword readability, customer characteristic keywords and brand characteristic keywords positively affect seller sales. The influence of these keyword characteristics on seller performance varied significantly across different product types.
Originality/value
The exploratory results of this study expanded existing studies by adding keyword characteristics to the factors that determine e-commerce platform seller performance and expanded the literature that mainly examines search engine keyword characteristics. In addition, by newly utilizing the LIWC (Linguistic Inquiry and Word Count) methodology, this study provided a novel contribution to the literature on keyword characteristics.

Abstract
Purpose
The purpose of this study is to analyze the effect on movie performance of the breadth and depth of consumer groups targeted by movies and to analyze the ways in which electronic word-of-mouth (eWOM) mediates these relationships.
Design/methodology/approach
For empirical analysis, 45 days of sales and eWOM data for 63 movies released in Korea in 2017 were collected, and a panel regression analysis was conducted on a total of 2,835 data items. In addition, the analysis was rigorously verified through three robustness tests.
Findings
The breadth and depth of consumer groups targeted by movies have a non-linear relationship with sales, and this relationship is mediated by the eWOM performance of social media websites. In addition, eWOM performance has a non-linear relationship with sales, and these effects differ depending on the type of eWOM platform involved.
Originality/value
The effects of the breadth and depth of the consumer groups targeted by movies on eWOM performance and movie performance have not been sufficiently investigated. This paper expands on previous studies that reported a linear relationship between eWOM and sales by finding that the effects of consumer group breadth and depth on sales are not linear in terms of the mediation of eWOM performance. In addition, a new research direction is suggested by conceptualizing consumer group breadth and depth using eWOM data, on which basis the new concept of eWOM-to-viewing ratio (eWOM ratio) is proposed.

Abstract
Purpose
The purpose of this study is to analyze the nonlinear effects of corporate philanthropy on the responses of both internal and external stakeholders as well as its impact on corporate financial performance.
Design/methodology/approach
Based on the stakeholder theory, the authors developed a conceptual model to examine the nonlinear effects of corporate philanthropy on company performance. For the empirical analysis, data from 397 company-years was analyzed using a using a Heckman two-stage model. The robustness of the findings was also confirmed through panel regression analysis.
Findings
The study revealed a linear relationship between corporate reputation and corporate philanthropy, whereas job satisfaction exhibited a nonlinear relationship with corporate philanthropy.
Originality/value
This research bridges the gap in extant literature by scrutinizing the nonlinear associations between corporate philanthropy and financial performance. Additionally, it addresses an emerging scholarly demand to uncover the “dark side” of corporate philanthropy through an investigation into its adverse impacts on employee satisfaction. Moreover, the study augments existing understandings of stakeholder theory and corporate philanthropy, positing that the influence of corporate philanthropy, as conceptualized through stakeholder theory, hinges on perceived fairness in multilateral relationships.

Abstract
The purpose of this study is to understand what health and safety hazards low-income households are subject to by surveying the real conditions of the defective housing of low-income households, and to find improvement strategies. For this purpose, we visited the concentrated areas of the multi-dwelling unit (MDU) (also known as multi-family residential) housing in Jungwon-gu and Sujeong-gu in Seongnam City, Kyunggi-do, one of the representative areas in Korea with a massive distribution of the low-income class. Based on the survey data, the level of housing defects were comparison analyzed per income decile (decile 1, decile 2, deciles 3–4), and per housing location, in the categories of subsidence, cracks in the wall, delamination, water leakage/infiltration, condensation, and contamination. The housing condition per income class was more defective in the decile 2 households rather than in the decile 2 households, and in the substructure more than in the superstructure. Among the six defects, contamination problems, caused by sub-standard living conditions, were the most frequent cases. Structural defects, subsidence and cracks in the wall, were found in the main living areas—the bedrooms and the living rooms. It was confirmed in this study that the conditions of low-income housing are serious, and that it is necessary to explore specific countermeasures in the near future.

Abstract
Purpose
This study aims to examine and understand South Korea’s (S. Korea) COVID-19 response operations, a notable case for other countries to emulate, and suggest some practical implications for other countries struggling with coping with the current pandemic.
Design/methodology/approach
To examine the case, the authors propose a new theoretical framework based on concepts of the whole community approach in the emergency management field and on co-production in public administration studies, and use the theoretical framework to analyze the details of S. Korea’s whole community co-production for COVID-19 response.
Findings
The findings demonstrate that the successful pandemic response in S. Korea is attributable to a nationwide whole community co-production among multiple actors, including government, various industries, sectors, jurisdictions and even individual citizens, within and across relevant public service and public policy domains.
Originality/value
This study suggests a new theoretical framework, whole community co-production, which contributes to the conceptual advancement of co-production in the field of public administration and a whole community approach in the field of emergency and crisis management. The framework also suggests practical implications for other countries to integrate whole community coproduction that may transform current response operations to cope with COVID-19.

Abstract
Purpose
Major changes of an aircraft configuration are conducted during the early design stage. It is important to include the airworthiness regulations at this stage while there is extensive freedom for designing. The purpose of this paper is to introduce an efficient design framework that integrates airworthiness guidelines and documentation at the early design stage.
Design/methodology/approach
A new design and optimization process is proposed that logically includes the airworthiness regulations as design parameters and constraints by constructing a certification database. The design framework comprises requirements analysis, preliminary sizing, conceptual design synthesis and loads analysis. A design certification relation table (DCRT) describes the legal regulations in terms of parameters and values suitable for use in design optimization.
Findings
The developed framework has been validated and demonstrated for the design of a Federal Aviation Regulations (FAR) 23 four-seater small aircraft. The validation results show an acceptable level of accuracy to be applied during the early design stage. The total mass minimization problem has been successfully solved while satisfying all the design requirements and certification constraints specified in the DCRT. Moreover, successful compliance with FAR 23 subpart C is demonstrated. The proposed method is a useful tool for design optimization and compliance verifications during the early stages of aircraft development.
Practical implications
The new certification database proposed in this research makes it simpler for engineers to access a large amount of legal documentation related to airworthiness regulations and provides a link between the regulation text and actual design parameters and their bounds.
Originality/value
The proposed design optimization framework integrates the certification database that is built of several types of legal documents such as regulations, advisory circulars and standards. The Engineering Requirements and Guide summarizes all the documents and design requirements into a single document. The DCRT is created as a summary table that indicates the design parameters affected by a given regulation(s), the design stage at which the parameter can be evaluated and its value bounds. The introduction of the certification database into the design optimization framework significantly reduces the engineer’s load related for airworthiness regulations.
