This chapter explores the elements influencing online reviews' usefulness by focusing on the language that consumers use when writing online reviews and on reviewers' attributes. By using text mining tools, the authors investigate how reviews' language affects their usefulness perception (i.e., the number of times readers have marked them as useful). The dataset consists of more than 54,000 online reviews from the most frequently used e-WOM source currently available and covers the period 2005-2017. The results suggest that word count and some of reviews' linguistic features (e.g., the subjectivity score, authenticity score) influence their usefulness perception. Reviewers' attributes (i.e., their number of reviews, age, class, and gender) also affect their reviews' perceived usefulness. The chapter concludes by describing the study results' implications for theory development, for empirical research, and for managerial practice.

Heavy Pollution

Environmental information disclosure (EID) of listed companies is a significant and essential reference for assessing their environmental protection commitment. However, the content and form of EID are complex, and previous assessment studies involved manual scoring mainly by the experts in this field. It is subjective and has low timeliness. Therefore, this paper proposes an automatic evaluation framework of EID quality based on text mining (TM), including the EID index system’s construction, automatic scoring of environmental information disclosure quality, and EID index calculation. Furthermore, based on the EID of 801 listed companies in China’s heavy pollution industry from 2013 to 2017, case studies are conducted. The case study results show that the overall quality of the EID of listed companies in China’s heavily polluting industries is low, and there is a gap differentiation between the 16 industries. Compared with the subjective manual scoring method, TM evaluation can evaluate the quality of EID more effectively and accurately. It has great potential and can become an essential tool for the sustainable development of society and listed companies.

SummaryAlthough factor V Leiden (FVL) is a major determinant of thrombotic risk, the reason why less than 10% of carriers eventually develop venous thromboembolic (VTE) events is unknown. Recent observations suggest that circulating levels of microparticles (MP) may contribute to the thrombogenic profile of FVL carriers. We measured the plasma level of annexin V-MP (AMP) platelet-MP (PMP), endothelial-MP (EMP), leukocyte-MP (LMP) and tissue factor-bearing MP (TF+MP), and the MP procoagulant activity (PPL) in 142 carriers of FVL (of these 30 homozygous and 49 with prior VTE), and in 142 age and gender-matched healthy individuals. The mean (± SD) level of AMP was 2,802 ± 853 MP/ μl in carriers and 1,682 ± 897 in controls (p<0.0001). A statistically significant difference between homozygous and heterozygous carriers of FVL was seen in the level of PMP, EMP and LMP, but not in that of the remaining parameters. When the analysis was confined to carriers with and without a VTE history, the mean level of AMP was 3,110 ± 791 MP/ μl in the former, and 2,615 ± 839 MP/μl in the latter (p<0.005). The mean level of all subtypes of circulating MP showed a similar pattern. The PPL clotting time was 39 ± 9 seconds (sec) in carriers, and 52 ± 15 sec in controls (p=0.003); and was 35 ± 8 sec in carriers with prior thrombosis, and 41 ± 10 sec in thrombosis-free carriers (p<0.005). Our study results suggest that circulating MP may contribute to the development of thrombosis in carriers of FVL mutation.

This article is a part of a Doctoral Thesis titled “Isaan Heritage Tree: From the Belief and the Aesthetic to the Creation of Visual Arts,” with the objectives of studying the belief and the aesthetic that exist in the Isaan Heritage Tree using the qualitative method. The study’s target groups can be divided into three following groups: the experts, the practitioners, and the related people. The area of study is in the Isaan region. The region is divided into upper Isaan, mid-Isaan, and lower Isaan. The research tools consist of surveys, non-participatory observation, and structured and non-structured interviews. The data collected from documents and field data was analyzed using Aesthetic Theory and Symbolic Interactionism Theory and presented using descriptive analysis.  The study results show that Isaan has a long history and development both in geography, the administration, society, the culture, and the migration of people who came to settle in the area from Luang Phrabang, Vientiane, and Champasak. This had caused the people and nation’s coming together and led to social management, which consists of regulations, religion, and belief. The beliefs of the Isaan people are connected to forest spirits, household spirits, or tree spirits. Five following characteristics of the Heritage Trees were also found: 1) The traditional beliefs related to the Heritage Trees of Isaan. 2) The new belief. 3) The beliefs that are connected to the locations. 4) The beliefs in the tree spirits whose identity and gender cannot be identified. 5) Auspicious and inauspicious beliefs. There are three aspects for the aesthetics: Aesthetic elements are the feeling of amazement due to the gigantic size filled with astonishment, mystery, and the fear of power. The interesting aspects of Art elements are the unity and relationship to the seasons, such as the Fall season, Rainy Season, and the blooming of flowers that contribute to the changes in the aesthetics changes. The visual art elements consist of six following components; bodies and shapes, lines, colors, textures, light and shadows, and area. It was found that the gigantic size and height cause amazements to the viewers. The physical lines of the Isaan Heritage trees were the lines along the trunks, the lines on the branches, and the lines that go along the leaves and flowers. There are different colors of the trunk, the leaves, and the flowers. The texture was rough, harsh, and the cracks follow the same directions as the trunk. There are botanical differences in the light and shadows of the heritage trees. As for the area, there are differences between the area of the heritage trees and the surrounding areas, as well as the differences within the Isaan Heritage Trees area.   Received: 25 January 2021 / Accepted: 31 March 2021 / Published: 10 May 2021

Study Results

Although technology trends and acceptance have been considered crucial topics, limited research has examined stress-specific factors such as health anxiety in the context of the COVID-19 pandemic based on people’s attitudes toward a mobile health app using the Technology Acceptance Model (TAM). Accordingly, this study primarily highlights the psychological determinants stemming from the COVID-19 pandemic that affect the usage of a mobile health app. The study followed a cross-sectional design and adopted a snowball sampling technique to collect the data. The findings showed a significant association between perceived usefulness, perceived ease of use, and event-related fear and Tabaud App intention. The relationships between Tabaud App intention and COVID-19 anxiety on Tabaud App usage were also revealed. The study found a significant association between perceived ease of use and perceived usefulness. Additionally, the multi-group analysis showed that only two paths related to Tabaud App intention, perceived ease of use and perceived usefulness, differed significantly between males and females. Additionally, women experienced anxiety disorders more than men. The study contributes to the previous knowledge on the field by examining the psychological determinants resulting from the COVID-19 pandemic that influence using a mobile health app, namely, event-related fear and COVID-19 anxiety. The study results may help governments, health policymakers, and health organisations in Saudi Arabia contain the spread of the COVID-19 pandemic.

Development Approach

Purpose Through a data-driven theory development approach, this study builds on affordance theory and demonstrates how online mobile app reviews can be analyzed to understand the drivers of informal mobile learning success.Design/methodology/approach Textual big data provide a wealth of information regarding user–app relationships and various facets of user engagement. Adopting structural topic modeling and sentiment analysis, the authors extract latent topics from reviews of two educational apps: Duolingo and Photomath.Findings The findings suggest that the quality of the relationship between users and mobile learning apps is significantly reliant on how underlying affordances have been actualized. While affordances can leverage satisfaction, they may also be a source of frustration in case of any failure in their design or integration. The analysis reveals eight emergent affordances: practicality, affordability, information reliability, instruction integrity, hedonic experience, user-friendliness, interactive input and iterative upgrading.Research limitations/implications Since affordances of a technology entail both enablement and constraint and are best studied as a bundle of connected elements influencing each other reciprocally, the authors discuss how to address potential challenges from technical aspects to the added value of using mobile learning apps.Originality/value The results demonstrate that qualitative information in online reviews about mobile learning app experiences is of significant value. The approach demonstrates how advanced analytics can provide business value by addressing the evolving nature of customer needs and expectations. It proves the value of online reviews in discovering underlying technology affordances and their potential boundaries and challenges.

BACKGROUND Prior research has highlighted gender differences in online physician reviews, however, to date no research has linked online ratings with quality of care. OBJECTIVE To compare a consumer-generated measure of physician quality (online ratings) with a clinical quality outcome (sanctions for malpractice or improper behavior), to understand how patients’ perception and evaluation of doctors differ based on the physician’s gender and quality. METHODS We use data from a large online doctor reviews website and the Federation of State Medical Boards. We implement paragraph vector methods to identify words that are specific to and indicative of the separate groups of physicians. We then enrich these findings by utilizing the NRC word-emotion association lexicon to assign emotional scores to the various segments: gender, gender and sanction, and gender and rating. RESULTS We find significant differences in the sentiment and emotion of reviews for male and female physicians. We find that numerical ratings are lower and the sentiment in text reviews is more negative for women who will be sanctioned than for men who will be sanctioned; sanctioned male doctors are still associated with positive reviews. CONCLUSIONS Conclusions: Given the growing impact of online reviews on demand for physician services, understanding the different reviews faced by male and female physicians is important for consumers and for platform architects in order to revisit their platform design.

And Gender

This cross-cultural study investigated country and gender differences among American (U.S.A.) and Japanese students’ reading motivation. Fourth-grade students (94 from the United States and 102 from Japan) were administered a reading motivation questionnaire. Study results indicated American students had higher reading motivation than Japanese students on most dimensions, including Self-Efficacy, Challenges, Curiosity, Importance, Involvement, Recognition, Grades, Competition, and Social. We found that culture may impact students’ reading motivation and discuss how individualistic and collectivistic cultures influence students’ reading motivation. Contrasting with the existing research, this study did not show any significant gender differences in reading motivation across the two countries. The null effect of gender needs to be re-examined in future studies.
