Abstract

Purpose

The purpose of this paper is to create an automatic interpretation of the results of the method of multiple correspondence analysis (MCA) for categorical variables, so that the nonexpert user can immediately and safely interpret the results, which concern, as the authors know, the categories of variables that strongly interact and determine the trends of the subject under investigation.

Design/methodology/approach

This study is a novel theoretical approach to interpreting the results of the MCA method. The classical interpretation of MCA results is based on three indicators: the projection (F) of the category points of the variables in factorial axes, the point contribution to axis creation (CTR) and the correlation (COR) of a point with an axis. The synthetic use of the aforementioned indicators is arduous, particularly for nonexpert users, and frequently results in misinterpretations. The current study has achieved a synthesis of the aforementioned indicators, so that the interpretation of the results is based on a new indicator, as correspondingly on an index, the well-known method principal component analysis (PCA) for continuous variables is based.

Findings

Two (2) concepts were proposed in the new theoretical approach. The interpretative axis corresponding to the classical factorial axis and the interpretative plane corresponding to the factorial plane that as it will be seen offer clear and safe interpretative results in MCA.

Research limitations/implications

It is obvious that in the development of the proposed automatic interpretation of the MCA results, the authors do not have in the interpretative axes the actual projections of the points as is the case in the original factorial axes, but this is not of interest to the simple user who is only interested in being able to distinguish the categories of variables that determine the interpretation of the most pronounced trends of the phenomenon being examined.

Practical implications

The results of this research can have positive implications for the dissemination of MCA as a method and its use as an integrated exploratory data analysis approach.

Originality/value

Interpreting the MCA results presents difficulties for the nonexpert user and sometimes lead to misinterpretations. The interpretative difficulty persists in the MCA's other interpretative proposals. The proposed method of interpreting the MCA results clearly and accurately allows for the interpretation of its results and thus contributes to the dissemination of the MCA as an integrated method of categorical data analysis and exploration.

Abstract

Purpose

This study aims to address the growing importance of online health information (OHI) and the associated uncertainty. Although previous research has explored factors influencing the credibility of OHI, results have been inconsistent. Therefore, this study aims to identify the essential factors that influence the perceived credibility of OHI by conducting a meta-analysis of articles published from 2010 to 2022. The study also aims to examine the moderating effects of demographic characteristics, study design and the platforms where health information is located.

Design/methodology/approach

Based on the Prominence-Interpretation Theory (PIT), a meta-analysis of 25 empirical studies was conducted to explore 12 factors related to information content and source, social interaction, individual and media affordance. Moderators such as age, education level, gender of participants, sample size, platforms and research design were also examined.

Findings

Results suggest that all factors, except social support, have significant effects on the credibility of OHI. Among them, argument quality had the strongest correlation with credibility and individual factors were also found to be relevant. Moderating effects indicate that social support was significantly moderated by age and education level. Different sample sizes may lead to variations in the role of social endorsement, while personal involvement was moderated by sample size, platform and study design.

Originality/value

This study enriches the application of PIT in the health domain and provides guidance for scholars to expand the scope of research on factors influencing OHI credibility.

Abstract

Purpose

This viewpoint will present some statistical information about employee ownership in the US and interpret and analyze this information in order to address the barriers question using material from qualitative interviews that the authors have conducted over the last ten years with practitioners in the field. There have been few actual empirical studies that sort out the different barriers to employee ownership. The authors have chosen to focus on employee stock ownership plan (ESOP) in the US because this is the principal example from which people could learn from, and the high prevalence of ESOPs plays an important role in the US. This overview will present interpretations of these interviews with conceptual arguments that cannot always be supported with either overwhelming empirical studies or arguments that conclusively eliminate one or other explanation. This is an initial attempt to bring some comprehensive treatment and data to this incipient discussion. This is based on an interpretive analysis of qualitative interviews without quantification or social survey methods used for measurement. The advantage of this approach is that it lays out a completely different level of analysis of the barriers to employee ownership in the US that is “closer to the ground” and more based in the views of front-line practitioners who are actually implementing it.

Design/methodology/approach

Analysis and interpretation of qualitative interviews.

Findings

The list of barriers that has been identified is not exhaustive. The preliminary conclusions are that (not necessarily in this order) limitations of investment banking models, poor supportive infrastructure, complexity and cost and regulatory issues, the lack of support by political parties and social movements, the sale of companies due to financial considerations and legal complexities and lack of clarity and resistance by Federal agencies are major barriers in the US. Various sectors of Wall Street has been amenable to employee ownership with the proper government and private sector support. What is needed now is a series of quantitative surveys and qualitative interviews of retiring business owners in closely held companies and of CEOs and CFOs in stock market companies in order to gauge the barriers that they believe are blocking their own action in the employee share ownership area. The Rutgers Institute for the Study of Employee Ownership and Profit Sharing is working on such a research agenda at this time. In addition, with the future size of the US employee ownership sector at stake, a more intensive one-year interview project would make sense in order to present these different explanations to key actors and practitioners and ask them to provide evidence to prove or disprove the relevance of the different barriers.

Research limitations/implications

Empirical research which can resolve which barriers are more important than others is presented, when possible; however, studies that provide metrics to compare different barriers are not available and need to be carried out.

Practical implications

Other countries considering employee ownership policies can learn from the US experience. US policymakers and legislators can learn from an original, recent discussion of barriers.

Social implications

If employee ownership sectors are to be developed, a careful discussion of barriers is most relevant.

Originality/value

Original document by the authors based on original interviews.

Abstract

Purpose

Data storytelling courses position students as agents in creating stories interpreted from data about a social problem or social justice issue. The purpose of this study is to explore two research questions: What themes characterized students’ iterative development of data story topics? Looking back at six years of iterative feedback, what categories of data literacy pedagogy did instructors engage for these themes?.

Design/methodology/approach

This project examines six years of data storytelling final projects using thematic analysis and three years of instructor feedback. Ten themes in final projects align with patterns in feedback. Reflections on pedagogical approaches to students’ topic development suggest extending data literacy pedagogy categories – formal, personal and folk (Pangrazio and Sefton-Green, 2020).

Findings

Data storytelling can develop students’ abilities to move from being consumers to creators of data and interpretations. The specific topic of personal data exposure or risk has presented some challenges for data literacy instruction (Bowler et al., 2017). What “personal” means in terms of data should be defined more broadly. Extending the data literacy pedagogy categories of formal, personal and folk (Pangrazio and Sefton-Green, 2020) could more effectively center social justice in data literacy instruction.

Practical implications

Implications for practice include positioning students as producers of data interpretation, such as role-playing data analysis or decision-making scenarios.

Social implications

Data storytelling has the potential to address current challenges in data literacy pedagogy and in teaching critical data literacy.

Originality/value

Course descriptions provide a template for future data literacy pedagogy involving data storytelling, and findings suggest implications for expanding definitions and applications of personal and folk data literacies.

Abstract

Purpose

Replication is a primary self-correction device in science. In this paper, we have two aims: to examine how and when the results of replications are used in management and organization research and to use the results of this examination to offer guidelines for improving the self-correction process.

Design/methodology/approach

Study 1 analyzes co-citation patterns for 135 original-replication pairs to assess the direct impact of replications, specifically examining how often and when a replication study is co-cited with its original. In Study 2, a similar design is employed to measure the indirect impact of replications by assessing how often and when a meta-analysis that includes a replication of the original study is co-cited with the original study.

Findings

Study 1 reveals, among other things, that a huge majority (92%) of sources that cite the original study fail to co-cite a replication study, thus calling into question the impact of replications in our field. Study 2 shows that the indirect impact of replications through meta-analyses is likewise minimal. However, our analyses also show that replications published in the same journal that carried the original study and authored by teams including the authors of the original study are more likely to be co-cited, and that articles in higher-ranking journals are more likely to co-cite replications.

Originality/value

We use our results to formulate recommendations that would streamline the self-correction process in management research at the author-, reviewer- and journal-level. Our recommendations would create incentives to make replication attempts more common, while also increasing the likelihood that these attempts are targeted at the most relevant original studies.

Abstract

Purpose

The authors conducted a study at a history museum with the objective of examining changes in the knowledge of students aged 12 to 14 concerning the use of primary sources.

Design/methodology/approach

Students utilized self-led guides while exploring two museum spaces presenting different historical events. These guides encouraged students to scrutinize the exhibits, become acquainted with the methods employed in their research, and develop an awareness of the information derived from them. Students' responses to pre- and postquestionnaires were compared and analyzed using mixed methods.

Findings

The results revealed that students became familiar with various types of primary sources, recognized that only specific sources endure through time and gained an understanding of the research methods employed to study them. Additionally, most students comprehended that the same sources could lead to diverse historical accounts and the potential reasons for such variations.

Practical implications

Recommendations for practice are discussed.

Originality/value

This study contributed to the limited knowledge regarding learning during a single, self-led tour in a history museum. The findings illuminate the potential for learning and advancing historical thinking concepts even within such museum-visit contexts.

Abstract

Purpose

An increasing number of images are generated daily, and images are gradually becoming a search target. Content-based image retrieval (CBIR) is helpful for users to express their requirements using an image query. Nevertheless, determining whether the retrieval system can provide convenient operation and relevant retrieval results is challenging. A CBIR system based on deep learning features was proposed in this study to effectively search and navigate images in digital articles.

Design/methodology/approach

Convolutional neural networks (CNNs) were used as the feature extractors in the author's experiments. Using pretrained parameters, the training time and retrieval time were reduced. Different CNN features were extracted from the constructed image databases consisting of images taken from the National Palace Museum Journals Archive and were compared in the CBIR system.

Findings

DenseNet201 achieved the best performance, with a top-10 mAP of 89% and a query time of 0.14 s.

Practical implications

The CBIR homepage displayed image categories showing the content of the database and provided the default query images. After retrieval, the result showed the metadata of the retrieved images and links back to the original pages.

Originality/value

With the interface and retrieval demonstration, a novel image-based reading mode can be established via the CBIR and links to the original images and contextual descriptions.

Abstract

Purpose

The purpose of this paper is to develop a software-library in the R programming language that implements the concepts of the interpretive coordinate, interpretive axis and interpretive plane. This allows for the automatic and reliable interpretation of results from the multiple correspondence analysis (MCA) as previously proposed and published. Consequently, the users can seamlessly apply these concepts to their data, both via R commands and a corresponding graphical interface.

Design/methodology/approach

Within the context of this study, and through extensive literature review, the advantages of developing software using the Shiny library were examined. This library allows for the development of full-stack applications for R users without the need for knowledge of the corresponding technologies required for the development of complex applications. Additionally, the structural components of a Shiny application were presented, leading ultimately to the proposed software application.

Findings

Software utilizing the Shiny library enables nonexpert developers to rapidly develop specialized applications, either to present or to assist in the understanding of objects or concepts that are scientifically intriguing and complex. Specifically, with this proposed application, the users can promptly and effectively apply the scientific concepts addressed in this study to their data. Additionally, they can dynamically generate charts and reports that are readily available for download and sharing.

Research limitations/implications

The proposed package is an implementation of the fundamental concepts of the exploratory MCA method. In the next step, discoveries from the geometric data analysis will be added as features to provide more comprehensive information to the users.

Practical implications

The practical implications of this work include the dissemination of the method’s use to a broader audience. Additionally, the decision to implement it with open-source code will result in the integration of the package’s functions by other third-party user packages.

Originality/value

The proposed software introduces the initial implementation of concepts such as interpretive coordination, the interpretive axis and the interpretive plane. This package aims to broaden and simplify the application of these concepts to benefit stakeholders in scientific research. The software can be accessed for free in a code repository, the link to which is provided in the full text of the study.

Abstract

Purpose

This paper aims to explore how historical context influences the content and selection of rhetorical legitimation strategies. Using case study method, this paper will focus on how insurance companies and labor tried to defend their legitimacy in the context of enactment of Medicare in the USA. What factors influenced the strategic (rhetorical) decisions made by insurance companies and labor unions in their institutional work?

Design/methodology/approach

The study is empirically grounded in archival research, involving an analysis of over 9,000 pages of congressional hearings on Medicare covering the period 1958–1965.

Findings

The authors show that rhetorical legitimation strategies depend significantly on the specific historical circumstances in which those strategies are used. The historical context lent credibility to certain arguments and organizations are forced to decide either to challenge widely held assumptions or take advantage of them. The authors show that organizations face strong incentives to pursue the latter option. Here, both the insurance companies and labor unions tried to show that their positions were consistent with classical liberal ideology, because of high respect of classical liberal principles among different stakeholders (policymakers, voters, etc.).

Research limitations/implications

It is uncertain how much the results of the study could be generalized. More information about the organizations whose use of rhetorics the authors studied could have strengthened our conclusions.

Practical implications

The practical relevancy of the revised paper is that the authors should not expect hegemony challenging rhetorics from organizations, which try to influence legislators (and perhaps the larger public). Perhaps (based on the findings), this kind of rhetorics is not even very effective.

Social implications

The paper helps to understand better how organizations try to advance their interests and gain acceptance among the stakeholders.

Originality/value

In this paper, the authors show how historical context in practice influence rhetorical arguments organizations select in public debates when their goal is to influence the decision-making of their audience. In particular, the authors show how dominant ideology (or ideologies) limit the options organizations face when they are choosing their strategies and arguments. In terms of the selection of rhetorical justification strategies, the most pressing question is not the “real” broad based support of certain ideologies. Insurance company and labor union representatives clearly believed that they must emphasize liberal values (or liberal ideology) if they wanted to gain legitimacy for their positions. In existing literature, it is often assumed that historical context influence the selection of rhetorical strategies but how this in fact happens is not usually specified. The paper shows how interpretations of historical contexts (including the ideological context) in practice influence the rhetorical strategies organizations choose.
