Abstract

Purpose

The purpose of this paper is to describe the development of an electroosmotic dynamic model to simulate the transport phenomena in association with the electric therapy in modern medicine.

Design/methodology/approach

The present study builds a new model by employing SUPG finite element method to solve the electroosmotic transport equation in microchannels of human body.

Findings

The present electroosmotic finite element analysis demonstrated that the electric treatment has a better curative effect.

Research limitations/implications

The governing electric field equations for tissue fluids in microchannel include the Laplace equation for the effective electrical potential and the Helmholtz equation for the electrical potential established in the electric double layer (EDL). The transport equations governing the hydrodynamic field variables include the mass conservation equation for the electrolyte and the equations of motion for the incompressible charged fluids subject to an electroosmotic body force.

Practical implications

The phenomena of microchannels are dominated by elliptic equations, Laplace, Helmholtz and diffusion equations (Navier Stokes equations at Re=0.0259). These governing equations explain why the reaction of electric treatment is very fast, even immediate.

Originality/value

The analysis of the coupled hydrodynamic and electrical fields, the externally applied electric potential has been shown to be an aid to accelerate the tissue fluid due to the formation of an EDL. Interaction of plasma and tissue fluids in human body is also revealed.

Abstract

President Bill Clinton has had many opponents and enemies, most of whom come from the political right wing. Clinton supporters contend that these opponents, throughout the Clinton presidency, systematically have sought to undermine this president with the goal of bringing down his presidency and running him out of office; and that they have sought non‐electoral means to remove him from office, including Travelgate, the death of Deputy White House Counsel Vincent Foster, the Filegate controversy, and the Monica Lewinsky matter. This bibliography identifies these and other means by presenting citations about these individuals and organizations that have opposed Clinton. The bibliography is divided into five sections: General; “The conspiracy stream of conspiracy commerce”, a White House‐produced “report” presenting its view of a right‐wing conspiracy against the Clinton presidency; Funding; Conservative organizations; and Publishing/media. Many of the annotations note the links among these key players.

Abstract

This research aims to explore the impact of augmented reality (AR), the digital technology that superimposes virtual elements in a real environment, on consumers in the context of experiential marketing. Specifically, this study proposes a research model based on the stimulus-organism-response model, which considers AR media characteristics as external stimuli, consumers’ value perceptions as the organisms, and purchase intentions as the responses. The research model was tested with 248 consumers using structural equation modelling. The results show that informativeness, ease of use, and telepresence have positive effects on consumers’ utilitarian value perception and that telepresence and interactivity have positive effects on hedonic value perception. Overall, this study contributes to the growing body of knowledge on AR and provides actionable insights for managers implementing digital transformation strategies and AR applications in marketing practices.

Abstract

Purpose

This paper aims to test the differences in the consumer complaint behaviour of Asian and non‐Asian hotel guests in terms of culture dimensions. It also aims to examine the relationship between demographic factors (age, gender and education level) and complaint behaviour.

Design/methodology/approach

The paper adopts the Hofstede's typology of culture as a framework to investigate cultural differences and demographic characteristics in the complaint behaviour of hotel guests. A face‐to‐face interview survey is conducted to collect data in this research. Data are then analyzed by various statistical methods such as two‐way contingency table analysis, non‐parametric Mann‐Whitney U and Chi‐square tests.

Findings

The survey reveals that older complainants tend to resort to “public actions,” but people with a higher level of education tend not to complain publicly. In addition, Asian guests are less likely to complain to the hotel for fear of “losing face” and are less familiar with the channels for complaint than non‐Asian guests. They are more likely than non‐Asian guests to take private complaint action, such as making negative word‐of‐mouth comments. The findings also indicate that there is a significant relationship between “complaint encouraging factor” and respondents' nationality and between “effective complaint handling method” and respondents' nationality.

Originality/value

Few studies have focused on the cultural differences in complaint behaviour of Asians and non‐Asian hotel guests in the hotel industry. The result will be most valuable in assisting hotel managers and marketers to better understand the customer complaint behaviour and intentions both from the Asian and non‐Asian contexts, and help formulate strategies and tactics to effectively manage the customer complaint.

Abstract

We describe a holistic approach to promoting school safety that merges an emphasis on student voice with staff training in restorative practices. We first describe current approaches to keeping schools safe based on the existing research literature. Given that most of these approaches rely on access to credible information about potential threats to school safety, we then discuss student voices as one critical source of information, especially at the middle and high school level. We report on a recently developed tool designed to encourage students to share threats to school safety they are aware of with adults. Initial testing identified potential barriers and facilitators to students' willingness to share information. We discuss teacher training in restorative practices as one approach that might address some of these barriers, including anti-snitching cultures in schools, students' lack of trust in adult responses to student-identified concerns, and punitive school climates. Based on recent work, we identify barriers and facilitators to implementing restorative practices in schools. We provide recommendations about potential strategies to merge student voice with school personnel's training in restorative practices to minimize peer victimization that can escalate into violent behavior.

Abstract

This study assessed the mediation effect of perceived brand quality and the moderation effect of consumer ethnocentric tendency in the proposed consumption model of a global sports brand. The English Premier League was selected as a global sports brand and four hypotheses were established to explain how consumers' perceived brand globalness affected their watching intention. Data were collected from 302 collegians in Republic of Korea. Results showed that perceived brand quality partially mediated the relationship between perceived brand globalness and watching intention, and ethnocentrism played a moderating role. The findings contribute to our understanding of consumption activities of global sport brands.

Abstract

Purpose

The authors investigate whether abnormal tone in corporate narrative disclosures is associated with earnings management and earnings quality, in an emerging market context. Based on agency theory and opportunistic/impression management perspective, this study examines whether executives manage disclosure tone to support their opportunistic behavior, when using earnings management.

Design/methodology/approach

This study uses a sample of earnings press releases of publicly traded firms in the MENA region during 2014–2019. It employs textual analysis to measure disclosure tone. The authors estimate abnormal disclosure tone after controlling for firm characteristics. Discretionary accruals proxy for earnings management and are estimated using Modified Jones model. Earnings quality is measured using accounting-based and market-based proxies: earnings smoothness, persistence, predictability and value relevance/informativeness.

Findings

Results show a positive association between abnormal disclosure tone and earnings management. Additionally, results show that earnings persistence is higher for firms with lower levels of abnormal disclosure tone. Results are sustained for earnings smoothness, but not for predictability and value relevance/informativeness.

Research limitations/implications

Results provide initial evidence of management's use of tone management jointly with earnings management. This adds to prior studies adopting the opportunistic perspective of disclosure tone, through showing that discretionary tone in narrative disclosures can be strategically used by management to influence investors' perceptions.

Practical implications

The results provide valuable insight to board of directors, auditors and market participants on the possible biases emerging from tone of narrative disclosures in corporate reports. For regulators and standard-setters, results shed light on the need for regulations and rules beyond financial statements, to guide disclosure of narrative information in different corporate reports.

Originality/value

This study contributes to the rare evidence that investigates textual disclosure characteristics to uncover management's opportunistic practices and assess earnings quality. Where majority of studies concentrate on developed markets, this study provides novel evidence of emerging markets by examining the association between abnormal disclosure tone and earnings management/earnings quality. Also, it validates the tone management model proposed by Huang et al. (2014) for capturing tone manipulation.

Abstract

Purpose

To better understand executive communication on social media, the purpose of this paper is to examine the pattern of messages posted by chief executive officers (CEOs) on Twitter and their retweetability (rate of reposting by other users).

Design/methodology/approach

The study data comprises 1,068 original tweets randomly selected from all Fortune 1000 CEOs’ tweets in 2014. The impact of the contextual factors (industry background, activeness, and Twitter age) and content factors (content types, supplementary information, and linguistic features) on retweetability was examined through regression analyses.

Findings

CEOs tweet to share information and insights, to promote their companies or products, to update work or life status, and to interact with the public. Original insights, promotional messages, and seasonal greetings were most likely to be retweeted. CEOs’ backgrounds, usage of hashtags, and certainty of language were also positively associated with retweetability.

Practical implications

CEOs may enhance their online social influence through demonstrating leadership by sharing insights about their organization or industry and posting topical messages (e.g. season’s greetings). Furthermore, CEOs could use hashtags strategically to initiate or participate in discussions and promote their personal visibility.

Originality/value

This study is one of the first to evaluate how leaders of the largest companies in the USA communicate on Twitter. It contributes to a theoretical understanding of the factors underlying online influence – the influence of the status of the online communicator vs the message content on information forwarding.
