Thousands of preprints related to Covid-19 have effused into the academic literature. Even though these are not peer-reviewed documents and have not been vetted by medical or other experts, several have been cited, while others have been widely promoted by the media. While many preprints eventually find their way into the published literature, usually through integrated publishing streams, there is a small body of preprints that have been opaquely withdrawn/retracted, without suitable reasons, leaving only a vestigial or skeletal record online. Others have, quite literally, vanished. This paper aims to examine some of those cases.

For peer-reviewed literature, a retracted academic paper is usually water-marked with “RETRACTED” across each page of the document, as recommended by ethical bodies such as the Committee on Publication Ethics, which represents thousands of journals and publishers. Curiously, even though pro-preprint groups claim that preprints are an integral part of the publication process and a scholarly instrument, there are no strict, detailed or established ethical guidelines for preprints on most preprint servers. This paper identifies select withdrawn/retracted preprints and emphasizes that the opaque removal of preprints from the scholarly record may constitute unscholarly, possibly even predatory or unethical, behavior.

Strict ethical guidelines are urgently needed for preprints, and preprint authors, in the case of misconduct, should face the same procedure and consequences as standard peer-reviewed academic literature.

Journals and publishers that have silently retracted or withdrawn preprints should reinstate them, as for regular retracted literature, except for highly exceptional cases.

The purpose of this paper is to examine the construct of retail customer experience (CE) and its links to satisfaction and loyalty; and to test whether loyalty programmes perform a moderating effect on those links.

A variety of retail attributes are integrated to develop a holistic CE construct using formative measures, with four in-built, differentiated replication studies conducted in the supermarket and department store sectors in China.

The empirical results confirm the model of CE’s impact on customer satisfaction and loyalty; but reveal that loyalty programmes perform an insignificant moderating role in enhancing the linkages in the model.

Further studies may examine whether our findings hold true for each individual loyalty programme. The paper calls for more studies based on multiple, in-built, differentiated replication studies and measures to encourage publication of negative empirical results so as to ensure empirical generalization and self-correction in the literature.

Retail managers should focus attention on the design and delivery of great CE, without placing great reliance on loyalty programmes. Both cognitive and emotional attributes of retailing services should be considered for managing a holistic CE.

The paper examines a model of CE with loyalty programme as a possible moderator; it uses formative measures of CE, multiple in-built replications and reports negative empirical results, which are critical to the development of scientific progress in retail management research.

Whistle-blowing, which has become an integral part of the post-publication peer-review movement, is being fortified by social media. Anonymous commenting on blogs as well as Tweets about suspicions of academic misconduct can spread quickly on social media sites like Twitter. The purpose of this paper is to examine two cases to expand the discussion about how complex post-publication peer review is and to contextualize the use of social media within this movement.

This paper examines a Twitter-based exchange between an established pseudonymous blogger and science critic, Neuroskeptic, and Elizabeth Wager, the former COPE Chair, within a wider discussion of the use of social media in post-publication peer review. The paper also discusses false claims made on Twitter by another science watchdog, Leonid Schneider. The policies of 15 publishers related to anonymous or pseudonymous whistle-blowing are examined.

Four issues in the Neuroskeptic–Wager case were debated: the solicitation by Wager to publish in RIPR; the use of commercial software by Neuroskeptic to make anonymous reports to journals; the links between “publication ethics” leaders and whistle-blowers or pseudonymous identities; the issues of transparency and possible hidden conflicts of interest. Only one publisher (Wiley) out of 15 scientific publishers examined claimed in its official ethical guidelines that anonymous reports should be investigated in the same way as named reports, while three publishers (Inderscience, PLOS and Springer Nature) referred to the COPE guidelines.

No such Twitter-based case has yet been examined in detail in the publishing ethics literature.

The purpose of this paper is threefold: to measure and compare the degree of social media use (SMU) by football clubs, to assess football fans’ engagement with content posted by football clubs (FCs) and to evaluate differences in user engagement with commercial social media advertisement targeting football fans, based on the advertisements’ appeal.

This paper employs three approaches. First, it uses the corporate social media use (CSMU) model to analyse 20,954 Facebook, YouTube, Instagram and Twitter postings from 78 European FCs. Second, it develops a categorisation for social media postings and uses ANOVA and Scheffè tests to conduct a pairwise comparison. Third, it uses a fictional hedonic low-involvement product (chocolate bar) to conduct an experiment by creating a Facebook advertising campaign with three advertisements that are manipulated regarding their general appeal.

Study 1 demonstrates that individual FCs show big differences between their degree of SMU. There are, however, no differences between European leagues, social media platforms, or more/less successful FCs. The results of Study 2 indicate that social media users like, comment and share postings by FCs independently of the content of the posting. Study 3 reveals that both user engagement and reach of advertisements can be substantially increased by employing football-related appeals.

This paper helps understanding consumer engagement in social media. The results presented are relevant and helpful for a multitude of actors, including FCs and other sports clubs, companies targeting football fans and researchers interested in social media and sports marketing.

Means, medians and SD for available socio‐economic status (SES) black‐white differences are here substituted for those of IQ in a between‐groups model published by the author over a decade ago. The goodness of fit of the SES variables used is compared with that for the earlier IQ data. Even when SES variables are relatively successful this can be viewed as additional evidence of the importance of IQ differences to black‐white differences in delinquency.

This paper aims to investigate the characterization of corrections to the papers published in Library and Information Science (LIS) journals during 2006-2015. It studies the frequency and location of the published errors, time interval between the publication of the original papers and their corrections, as well as associations between journals’ impact factors (IF) and their correction rates.

The population of the study comprised of 369 errata published in 50 LIS journals. The data were obtained from Clarivate Analytics’ Web of Science (WoS) and Journal Citation Reports.

The results of the study revealed a correction rate of 0.37 per cent for LIS journals, which is substantially lower than that of 124 subject categories with at-least one erratum in the WoS. Among the countries with the highest number of errata in LIS journals, the USA ranked first, followed by China and England. However, the greatest share of errata to overall LIS publications of the country was seen in Kazakhstan, Russia and Botswana. Results showed that no statistically significant relationships existed between the journals’ IF and their correction rates. The highest proportion of errors published in LIS literature was occurred in authors’ information, references, tables and figures. Moreover, the average time from publication of the original articles to their corresponding errata was found to be 8.7 months.

Correcting the unintentional mistakes in scholarly articles is an ethical responsibility of researchers and journal editors.

The current research tries to investigate the characteristics of errata in the LIS field.

The purpose of this paper is to develop a quantitative model to assess probability of errors and errors correction costs in parts feeding systems for assembly lines.

Event trees are adopted to model errors in the picking-handling-delivery-utilization of materials containers from the warehouse to assembly stations. Error probabilities and quality costs functions are developed to compare alternative feeding policies including kitting, line stocking and just-in-time delivery. A numerical case study is included.

This paper confirms with quantitative evidence the economic relevance of logistic errors (LEs) in parts feeding processes, a problem neglected in the existing literature. It also points out the most frequent or relevant error types and identifies specific corrective measures.

While the model is general purpose, conclusions are specific to each applicative case and are not generalizable, and some modifications may be required to adapt it to specific industrial cases. When no experimental data are available, human error analysis should be used to estimate event probabilities based on underlying modes and causes of human error.

Production managers are given a quantitative decision tool to assess errors probability and errors correction costs in assembly lines parts feeding systems. This allows better comparing of alternative parts feeding policies and identifying corrective measures.

This is the first paper to develop quantitative models for estimating LEs and related quality cost, allowing a comparison between alternative parts feeding policies.

Part V analyzes the details of how to assess materiality. It first tackles qualitative versus quantitative criteria and the role of professional judgment. It then analyzes the selection of quantitative threshold, to expand to the choice of benchmarks. It contrasts the whole financial statements with subaggregates, line items, and components.

Specific sections contrast IASB, FASB, SEC, and other guidance on materiality applied to comparative information, interim reporting, and segment reporting.

The section on estimates mingles complex guidance coming from accounting, auditing, and internal control over financial reporting to explain how the management can improve its assessment of materiality concerning estimates.

After explaining the techniques to move from individual to cumulative misstatements, the part tackles verification ex post, and finally summarizes the intricacies of whether immaterial misstatements are permissible and their consequences.

Terminology and parameters for describing the relation between figures for the use of library literature and for its age are discussed. Unless a correction for growth is applied, half‐life fails a simple test of suitability, as do Brookes's ageing and utility factors. Results based on cumulated data have other important disadvantages. Relative ‘use‐per‐item’ figures are satisfactory. The need to relate terminology more closely to the facts they represent is stressed: item‐consultation decay rate, and 50% consultation probability age are suggested and defined. In the context of citation studies, item‐citation decay rate and 50% citation probability age are equivalent and avoid similar objections. In data from NRLSI, item‐consultation decay rates are only approximately exponential. Different rates are demonstrated for updating and basic searches, for academic and other types of readers, and for types of literature. For some historical searches negative decay rates were found in the NRLSI and BML.

This study aims to investigate the mediating role of positive affect and the moderating role of deficit correction in the relationship between employee strengths use and innovative behavior.

This study adopted a three-wave research design to gather data. A convenience sample of 189 employees working in diverse organizations in China was applied to examine the hypotheses.

The results indicated that employee strengths use was positively related to innovative behavior, and positive affect mediated the relationship between employee strengths use and innovative behavior. In addition, deficit correction enhanced the direct relationship of employee strengths use with positive affect and the indirect relationship of employee strengths use with innovative behavior through positive affect.

The current study contributes to the existing literature on employee strengths use-innovative behavior relationships by revealing positive affect as a mediator and deficit correction as a moderator between employee strengths use and innovative behavior.
