Abstract

Purpose

This paper aims to perform an exhaustive revision of relevant and recent related studies, which reveals that both extraction methods are currently used to analyze credibility on Twitter. Thus, there is clear evidence of the need of having different options to extract different data for this purpose. Nevertheless, none of these studies perform a comparative evaluation of both extraction techniques. Moreover, the authors extend a previous comparison, which uses a recent developed framework that offers both alternates of data extraction and implements a previously proposed credibility model, by adding a qualitative evaluation and a Twitter-Application Programming Interface (API) performance analysis from different locations.

Design/methodology/approach

As one of the most popular social platforms, Twitter has been the focus of recent research aimed at analyzing the credibility of the shared information. To do so, several proposals use either Twitter API or Web scraping to extract the data to perform the analysis. Qualitative and quantitative evaluations are performed to discover the advantages and disadvantages of both extraction methods.

Findings

The study demonstrates the differences in terms of accuracy and efficiency of both extraction methods and gives relevance to much more problems related to this area to pursue true transparency and legitimacy of information on the Web.

Originality/value

Results report that some Twitter attributes cannot be retrieved by Web scraping. Both methods produce identical credibility values when a robust normalization process is applied to the text (i.e. tweet). Moreover, concerning the time performance, Web scraping is faster than Twitter API and it is more flexible in terms of obtaining data; however, Web scraping is very sensitive to website changes. Additionally, the response time of the Twitter API is proportional to the distance from the central server at San Francisco.

Abstract

This chapter introduces linguistic delivery style to auditing research, demonstrates how linguistic delivery style relates to client credibility, and shows how linguistic delivery style and client credibility influences auditors’ judgment. Two hundred auditors participated in an analytical procedures task. The results indicate that high client credibility and powerful linguistic delivery style increase the auditor's assessed likelihood that the explanation accounts for the fluctuation and decrease their intent to perform additional testing. Moreover, powerless linguistic delivery style from an otherwise high credibility client leads to auditor judgments and intentions that are indistinguishable from those that arise from a low credibility client. Finally, evidence indicates that linguistic delivery style is a fourth component of credibility.

Abstract

Data were collected from loan officers using a computerized process-tracing program to help shed some light on how source credibility impacts the judgments made by loan officers. Loan officers did not structure loans more restrictively regardless of whether they were in the positive or negative character condition or whether they approved or denied the loan. Negative source credibility affected decision process effort but did not produce the tradeoff between loan approval and loan structure that is suggested in the literature. Although significantly more (fewer) loans were denied when character information was negative (positive), a majority of loan officers in the negative character condition approved the loan. While most loan officers were aware of negative source credibility, they did not react by denying loans or adjusting loan structure.

Abstract

Purpose

The purpose of this paper is to present a conceptual model that intends to identify the determinants and consequences of brand credibility, specifically in the pharmaceutical industry.

Design/methodology/approach

The hypotheses developed according to the proposed model were tested through an online questionnaire and answered by 225 individuals from Portugal.

Findings

The results show that the credibility of brand communication, perceived quality and brand familiarity are the key components that contribute most to the creation of a credible brand. Regarding consequences, this study confirms that, in the face of a credible brand, consumers are more willing to repeat the purchase, to pay more for it and to promote their opinion among other consumers.

Originality/value

This research innovates by presenting, for the first time, a conceptual model of brand credibility specific to the non-prescription medicines market, thus contributing to a better understanding of this issue by companies and brand managers of the pharmaceutical industry.

Abstract

Purpose: Many Internet users search for health information but they struggle with assessing the quality of the information they find. By drawing on a multi-modal approach to data collection, this study aims to understand further the nuanced cognitive processes that people utilize as they acquire and evaluate online health information.

Design: We used a mixed-methods approach that includes surveys, interviews, and observations of 76 diverse adults of all ages in the Chicago area completing various health information-seeking tasks.

Findings: Most participants begin their information-seeking process on search engines. We identified the most popular credibility-assessment strategies used on the search engine results’ pages (SERP) as well as on websites. We also explored how the process of executing such strategies reveals greater and lesser savvy among users.

Research Limitations: While the sample size and methods limit its generalizability, this study included a larger and more diverse group of participants than most observational work, which results in data about a wider range of behaviors than is typical of such research.

Social Implications: Our findings showed that most of our participants could use additional education regarding credibility assessment of online health information. Additionally, since a great deal of credibility assessment occurs on SERP, search companies bear a particular responsibility for ensuring the quality of the information their results highlight.

Abstract

Purpose

This study aims to investigate the factors that enhance the credibility of and confidence in audit value.

Design/methodology/approach

Data were collected from 254 institutional investors through a questionnaire survey and were analyzed using partial least squares structural equation modelling (PLS-SEM).

Findings

The findings reveal that the two influential predictors of enhanced credibility and confidence are perceived auditor independence and improved auditor communication. Factors related to auditor–client affiliation, such as restrictions on providing non-audit services, mandatory auditor rotation and the presence of effective audit committees, are identified as creating the perceived independence. Improved auditor communication is linked with improving the audit report and ensuring audit education, thus creating more sophisticated users who better understand the scope and purpose of an audit. Furthermore, independent audit oversight acts as a moderator in the relationship between perceived auditor independence, improved auditor communication and enhanced credibility. Enhanced credibility can lead to greater confidence in audit value.

Originality/value

In the wake of the global financial crisis and loss of confidence in the role of auditors, this study investigates the factors that can enhance the credibility of and confidence in audit value, especially in a non-Anglo-American setting. This study is unique in terms of methodological development, as it uses a higher-order Type II reflective–formative model using PLS-SEM.

Abstract

This study aims to investigate the relationships among corporate-brand credibility, product-brand personality, and purchase intention, specifically in China's auto industry. A large-scale survey was conducted in four major Chinese Mainland cities: Beijing, Shanghai, Guangzhou, and Chengdu. A total of 800 questionnaires were distributed for the study. Ultimately, 477 usable cases were collected for a 60 percent response rate. Results reveal that corporate-brand credibility and product-brand personality have direct positive effects on purchase intention. Furthermore, corporate-brand credibility acts as a positive moderator in the relationship between product-brand personality and purchase intention. This chapter offers new theoretical insights into the influential factors affecting consumers' purchase intentions by testing the moderating effect of corporate-brand credibility in the relationship between product-brand personality and purchase intention. It further provides useful suggestions to companies on brand credibility and personality issues.

Abstract

Purpose

The purpose of this exploratory study is to examine if and how victim credibility affects investigative decision-making and case outcomes in domestic violence and sexual assault reports through the use of the US Department of Justice's Gender Bias Principles (GBPs).

Design/methodology/approach

The authors conducted a content analysis of 370 DVSA police reports from one agency in the western US. Multivariate regression models were estimated to examine the relationships among victim credibility and investigative activities, victim cooperation and case clearance.

Findings

Victim credibility significantly predicts specific investigative actions and case clearance, but not victim cooperation. Multiple aspects of DVSA investigations significantly impact victim cooperation as well as case clearance, regardless of victim credibility issues. The GBPs are an effective framework for disaggregating investigative activities and identifying specific areas for improvement in policing response to DVSA.

Research limitations/implications

Further study is needed to determine the temporal ordering of officer assessment of victim credibility and investigative activities, the stability of such assessments during investigations, and if credibility problems noted in police reports are valid indicators of myth acceptance among officers or represent a downstream orientation of information requested by prosecutors. Victim service referral as a part of policing response is vastly under-researched given referral's strong effects on victim cooperation and case clearance. Crime-specific differences exist in many cases, yet not in others, suggesting separate and combined DVSA analyses are warranted.

Practical implications

A more complex analysis of investigative actions offers a targeted approach to officer training and administrative rule-making that may be more efficient and effective than current generalized approaches.

Originality/value

The study is the first to empirically test the utility of the GBP framework, as well as individual aspects of DVSA investigations, and from a gender-based crime rather than crime-specific approach.

Abstract

This paper is based on the conviction that school principal leadership varies considerably in accordance with the level of credibility they develop with the groups with which they interact. To become better leaders, school principals must adopt a proactive approach and develop the means of consolidating their credibility. Readers will understand that school principals have potential levers at their disposal, which can serve to enhance their credibility. We identified these levers by interviewing experienced school leaders. For each lever, we propose a series of actions and provide concrete examples. The text concludes with an overview and questions designed to guide readers in formulating their own individual action plans.
