Abstract

Purpose

No study has investigated the effects of different parameters on publication bias in meta-analyses using a machine learning approach. Therefore, this study aims to evaluate the impact of various factors on publication bias in meta-analyses.

Design/methodology/approach

An electronic questionnaire was created according to some factors extracted from the Cochrane Handbook and AMSTAR-2 tool to identify factors affecting publication bias. Twelve experts were consulted to determine their opinion on the importance of each factor. Each component was evaluated based on its content validity ratio (CVR). In total, 616 meta-analyses comprising 1893 outcomes from PubMed that assessed the presence of publication bias in their reported outcomes were randomly selected to extract their data. The multilayer perceptron (MLP) technique was used in IBM SPSS Modeler 18.0 to construct a prediction model. 70, 15 and 15% of the data were used for the model's training, testing and validation partitions.

Findings

There was a publication bias in 968 (51.14%) outcomes. The established model had an accuracy rate of 86.1%, and all pre-selected nine variables were included in the model. The results showed that the number of databases searched was the most important predictive variable (0.26), followed by the number of searches in the grey literature (0.24), search in Medline (0.17) and advanced search with numerous operators (0.13).

Practical implications

The results of this study can help clinical researchers minimize publication bias in their studies, leading to improved evidence-based medicine.

Originality/value

To the best of the author’s knowledge, this is the first study to model publication bias using machine learning.

Abstract

Purpose

Current publication practices in the scholarly (International) Business and Management community are overwhelmingly anti-Popperian, which fundamentally frustrates the production of scientific progress. This is the result of at least five related biases: the verification, novelty, normal science, evidence, and market biases. As a result, no one is really interested in replicating anything. In this essay, the author extensively argues what he believes is wrong, why that is so, and what we might do about this. The paper aims to discuss these issues.

Design/methodology/approach

This is an essay, combining a literature review with polemic argumentation.

Findings

Only a tiny fraction of published studies involve a replication effort. Moreover, journal authors, editors, reviewers and readers are not interested in seeing nulls and negatives in print. This replication crisis implies that Popper’s critical falsification principle is actually thrown into the scientific community’s dustbin. Behind the façade of all these so-called new discoveries, false positives abound, as do questionable research practices meant to produce all this allegedly cutting-edge and groundbreaking significant findings. If this dismal state of affairs does not change for the good, (International) Business and Management research is ending up in a deadlock.

Research limitations/implications

A radical cultural change in the scientific community, including (International) Business and Management, is badly needed. It should be in the community’s DNA to engage in the quest for the “truth” – nothing more, nothing less. Such a change must involve all stakeholders: scholars, editors, reviewers, and students, but also funding agencies, research institutes, university presidents, faculty deans, department chairs, journalists, policymakers, and publishers. In the words of Ioannidis (2012, p. 647): “Safeguarding scientific principles is not something to be done once and for all. It is a challenge that needs to be met successfully on a daily basis both by single scientists and the whole scientific establishment.”

Practical implications

Publication practices have to change radically. For instance, editorial policies should dispose of their current overly dominant pro-novelty and pro-positives biases, and explicitly encourage the publication of replication studies, including failed and unsuccessful ones that report null and negative findings.

Originality/value

This is an explicit plea to change the way the scientific research community operates, offering a series of concrete recommendations what to do before it is too late.

Abstract

Purpose

The article clarifies the wage–employment relation in a developing country. Several years ago, many articles in the United States indicated that the relation between increasing wages and increasing unemployment is unclear. These articles from the United States are insufficient to be applicable to all countries, especially developing countries such as Colombia where institutions and the wage–employment relation differ from those in the United States.

Design/methodology/approach

A meta-analysis methodology was used as 28 estimates of long-run wage–employment elasticity in Colombia from 1998 to 2016 were analyzed.

Findings

This article provides insights into how real wages affect employment. Despite publication biases, results showed that a 1% increase in wages results in a 0.11% decline in employment in the long run.

Research limitations/implications

Due to the publication bias, it is not considered how variables such as sectors, estimation strategies (panel data, partial adjustment, cointegration and non-linear least squares, among others), formal/informal urban sectors, government services and transportation, and qualified and unskilled workers affect the true elasticity value.

Practical implications

This paper includes implications for public policy because the results are important to minimum wages policy in a developing country.

Originality/value

There are no studies regarding the wage–employment relation in a developing country. The empirical results obtained in this article are useful for regulators, policy makers and researchers to understand whether employment is affected by real wages.

Abstract

Purpose

With the growing interest in behavioral health and medical decision-making, this systematic integrative review aims to understand research on cognitive biases in the context of consumer health information seeking and where future research opportunities may reside.

Design/methodology/approach

Following a systematic review protocol, 40 empirical research articles, out of 1,127 journal research papers from 12 academic databases, from 1995 to 2019, are included for review.

Findings

The study of cognitive biases in consumer health information seeking is a nascent and fast-growing phenomenon, with variety in publication venues and research methods. Among the 16 biases investigated, optimistic bias and confirmation bias have attracted most attention (46.9%). Researchers are most interested in specific disease/illness (35%) and the health factors of consumer products (17.5%). For theoretical presence, about one-third of the reviewed articles have cited behavioral economist Daniel Kahneman, although most of the references are the early works of Kahneman.

Research limitations/implications

As an emerging research area, there exists plenty of cognitive biases to be investigated in the context of health information seeking. In the meantime, the adoption of more recent theoretical insights such as nudge for debiasing may enrich this research area. Health communication scientists may find incorporating the behavioral decision research framework enriches the disciplinary inquiry of health information seeking, while information scientists could use it to commence the cognitive turn of information science evolution.

Originality/value

Through evidence-based understanding, this review shows the potential research directions that health communication scientists and information scientists could contribute to optimize health decisions through the adoption of behavioral decision research framework.

Abstract

Purpose

This paper aims to present the results of a recent survey, in which faculty and educators who are members of the ARES, ERES, AsRES, PRRES and AREUEA were asked to rate their perception of 18 real estate journals currently available as academic publications (peer reviewed) to ascertain if there was a relationship between the affiliation of the respondent and their perception of journal quality. In addition, it aims to compare the opinions of survey respondents by their academic rank, tenure status, and the type of institution they work at. Finally the analysis seeks to investigate the possible existence of a publication bias based on where researchers have published their work.

Design/methodology/approach

Over 300 respondents completed the electronic survey during the latter half of 2007. Respondents provided quality ratings of the journals as well as where they actually published.

Findings

In this paper the academic respondents’ responses were analyzed (n=220) and it is clear that the perceived quality of the journals, as well as the respondent's knowledge of the various journals, varied depending on the faculty member's affiliation with a given academic association. Most researchers were aware of the journals published in their home regions, although this was not always the case. This suggests there is a need for more outreach/marketing by publishers and editors to clearly differentiate the focus of our academic journals.

Research limitations/implications

Respondents were conference attendees and predominantly US‐based. Therefore, results may be somewhat biased against publications from other regions of the world.

Originality/value

This is the first time a review of journal quality has been conducted on an international level and included only real estate journals. Results will be useful to the rank and file of university faculty in targeting journals for their publications, particularly when journal quality matters. Results can also benefit the various academic organizations and publishers that produce the journals in targeting their promotion to the members of the academic associations where the knowledge level is significantly lower.

Abstract

Purpose

This paper aims to assess the cumulative evidence on the determinants of sustainability assurance (SA) reports and the choice of assurance provider quality. It addresses the contradictory and inconsistent findings of past studies conducted over the past two decades.

Design/methodology/approach

The authors undertake a meta-regression analysis that enables systematic, comparative assessment of the variables associated with the choice of SA and the type of assurance provider. The authors undertake a chronological analysis with the aim of identifying systematic differences in the empirical evidence across distinct time periods.

Findings

The results indicate that there is very little evidence to support many of the expected associations between commonly studied predictor variables (namely, measures based on agency and corporate governance conceptions) and the choice of SA and the assurance provider type. As a result, research on this topic does not make as effective a contribution as might be expected. There is, however, a time period difference. The authors find results from studies using company data prior to 2010 are significantly different from those using post-2010 data. The results indicate the decision to publish SA to be significantly associated with companies in the oil industry and utilities, and larger organisations where agency costs tend to be higher. Obtaining assurance from a higher-quality provider is found to be associated with companies in environmentally sensitive industries and in stakeholder-oriented countries.

Practical implications

The study shows that as yet there is not sufficient evidence to support expected results. Users of the research should be aware of this, and researchers should know that more work is needed. The authors suggest researchers take greater care in the choice and comparability of variable measurement and expand the conceptual base when selecting predictor variables.

Social implications

Companies need to be more transparent and accountable to critical stakeholders such as report users and regulators, and the latter should be more aware that the organisational practice of SA and choice of service provider have changed over time and are increasingly open to agency and other cultural biases.

Originality/value

To the best of the authors’ knowledge, this is the first study to apply meta-regression techniques for understanding the body of literature on SA and provider choice.

Abstract

Purpose

The purpose of this paper is to examine whether there are any systematic relationships between the characteristics of each study about immigrants' pro‐trade impacts and its results.

Design/methodology/approach

A meta‐analysis of 24 papers and 184 estimates that study the trade‐creating network effects of immigrants is employed.

Findings

The paper finds that, first, immigrant's trade‐creating effects are higher for English‐speaking countries than for non‐English‐speaking countries; second, immigrant's trade‐creating effects are higher for disaggregated data than for aggregated data; third, the trade‐creating effects seem declining over time. Besides, no evidence of publication bias has been found.

Research limitations/implications

This study relied heavily on case studies on developed countries.

Practical implications

Given strong evidence about the pro‐trade effects of immigrants and the unevenness of such effects, the world countries could reduce the cost and barriers for the movements of immigrants and thus help to increase international trade.

Originality/value

The paper is the first to use meta‐analysis to assess the pro‐trade effects of immigrants across different studies.

Abstract

Purpose

In this meta-analysis, the authors investigate the relationship between self-construal and conflict management strategies and shed light on the inconsistent findings in the literature. Moreover, they examine the mediating role of face concerns in this relationship. Importantly, the present meta-analysis is the first to test the assumptions of face-negotiation theory with the meta-analytic structural equation modeling (MASEM), which enabled the authors to test the hypothesized relationships in one single model.

Design/methodology/approach

The authors used the method of MASEM to test the relationship between self-construal and conflict management and assess the mediating role of face concerns. In this regard, the authors employed one-stage meta-analytic structural equation modeling to perform MASEM and its moderators.

Findings

Two hundred fifty-four effect sizes based on thirty-three studies were pooled in this meta-analysis. The authors found that individuals with stronger independent self-construal and stronger self-face concerns were more likely to use forcing. Moreover, the relationship between independent self-construal and forcing was mediated by self-face concerns. Individuals with a stronger interdependent self-construal and individuals with stronger other-face concerns were more likely to use problem-solving and yielding. The relationship between interdependent self-construal and problem-solving and yielding was mediated by other-face concerns. Finally, interdependent self-construal also had an indirect effect, via other-face concern, on avoiding and compromising.

Originality/value

The present meta-analysis is the first effort that the authors are aware of to test the assumptions of face-negotiation theory (FNT) using MASEM method. The authors used one-stage meta-analytic structural equation modeling viewed as the state of the methods to perform MASEM and its moderators. They employed full information meta-analytic structural equation modeling to show the generalizability and heterogeneity of structural equation modeling parameters. They applied studentized deleted residuals to assess outlier analysis and also conducted different methods to perform MASEM to check the robustness of the findings resulted. Finally, the current study adds multiple methods of assessing for publication bias.

Abstract

Purpose

The purpose of this study is to thoroughly review studies that have used blockchain technology in financial services. This study will help provide a holistic framework that would highlight the current state and challenges of the blockchain in the financial services sector.

Design/methodology/approach

The objective of this study is to systematically examine and organize the current body of research literature that either quantitatively or qualitatively explored the use of blockchain technology in financial services. The study uses PRISMA-guided systematic review along with bibliometric analysis to achieve the purpose.

Findings

This study contributes to the existing literature by exploring and analyzing systematic studies available on blockchain with special reference to financial services sector. With blockchain based on five principles, namely, computational logic, peer-to-peer transmission, irreversibility of records, distributed database and transparency with pseudonym has immense potential to unleash and transform the financial service industry. With increasing blockchain-based operations of decentralized banking, insurance, trade finance, financial markets and cryptocurrency market, the subject is rapidly growing and seeking considerable contribution from scholars from around the world.

Research limitations/implications

This study uses systematic literature review approach, which has its own demerits. Like other studies based on Systematic Literature Review, this study also suffers from a certain bias such as sample selection bias, publication bias, data interpretation and the combination of quantitative and qualitative studies in the population. Further, the adoption and resultant benefits of blockchain have not been empirically tested.

Practical implications

This study can help policymakers and institutions in determining their future course of action, as it highlights the state of research in the area of blockchain technology and financial services.

Originality/value

Very few studies have done a comprehensive review of literature on blockchain in financial services.

Abstract

Purpose

The purpose of this paper is to evaluate the global progress and explore research areas and development trends of open government data (OGD) field from the Web of Science (WOS) database by applying the bibliometric visualization approach.

Design/methodology/approach

This paper conducted a bibliometric mapping study on OGD scientific research publications based on WOS from six aspects.

Findings

There are six research perspectives on OGD research. European countries and developed countries pay more attention to OGD movement. The 20 most cited and highly influential research documents were identified. What’s more, the analysis of journals level highlights the interdisciplinary and cross-disciplinary characteristics of OGD research. Current six research topics for OGD research that have been formed and two major emerging research priorities in OGD research fields were identified.

Research limitations/implications

The limitation is that data retrieval result which decided to include only 180 publications in the WOS-indexed publications produced a bias against research publications published in non-WOS publication sources. A fuller research trend would be obtained with the more extensively used electronic databases.

Practical implications

By dint of bibliometric analysis, this paper may be able to quantify research patterns on OGD, to analyze what has been done in this field and to identify the main research hotspots. Therefore, it can aid academic researchers and practicing professionals in contributing to the field more effectively and advancing scientific progress in the field of OGD research.

Social implications

The results can also promote the study on OGD movement in academia, government and industry and also enrich the theory of OGD and provide some new perspectives for research on OGD.

Originality/value

This is the first study to quantify and evaluate global research patterns and development trends in OGD research based on WOS database, which provides a quantitative perspective on OGD studies that may assist in advancing the development of the field.
