Systematic analysis of the methodological structure of the lean literature
Authors: Francis Mark , Thomas Andrew , Fisher Ron 
Published: September 2021

PurposeThe purpose of this paper is to analyse and evaluate the methodological structure of the lean literature, so that its characteristics and influence among academics and practitioners might be better understood. The authors define “methodological structure” to be comprising six categorical components: publication category, degree of methodological disclosure, research strategies and data collection instruments (DCIs), type of data collected and analysed and type of research informants.Design/methodology/approachThis study is a systematic bibliometric analysis of the lean literature. It has a two-stage research design. The first stage involves the identification of the top 50 most highly cited publications on “Lean”, with the resultant reference details being entered into a focal population set (FPS) spread sheet. The second stage involves coding and adding the six component fields of the methodological structure for each of the FPS entries. Both citation analysis (CA) and publication counting are then used to analyse patterns in these six components of methodological structure.FindingsThe top 50 publications in the FPS represent over 52,700 citations. All are either journal papers or books, but books are the most influential. Based upon this FPS sample, the lean literature is found to be both largely atheoretical in nature and also methodologically weak. Over half of the FPS publications are viewpoint-type publications and 46% have no methodological disclosure. The lean literature is predominantly qualitative in nature. Where disclosed, the most common research strategy is the case study and the most common DCI is the interview. High- and mid-level managers are the most frequently encountered research informants, while shop floor workers are infrequently used.Originality/valueThis paper starts with the most extensive known systematic review of systematic reviews of the lean literature; the result of which is the characterisation of a number of gaps in this body of knowledge. One of these gaps is the lack of any previous CA. The paper then proceeds to address this gap by providing the first CA within the lean literature. This is also the most comprehensive known CA within the field of operations and supply chain management more generally. As a consequence of this analysis, previously unknown patterns and insights into the methodological structure of the lean literature are revealed.
Mining numerical measure of consumers’ product evaluation expressed in words based on latent Dirichlet allocation
Authors: Wang Ziang , Yang Feng 
Published: September 2021

Purpose
It has always been a hot topic for online retailers to obtain consumers’ product evaluations from massive online reviews. In the process of online shopping, there is no face-to-face interaction between online retailers and customers. After collecting online reviews left by customers, online retailers are eager to acquire answers to some questions. For example, which product attributes will attract consumers? Or which step brings a better experience to consumers during the process of shopping? This paper aims to associate the latent Dirichlet allocation (LDA) model with the consumers’ attitude and provides a method to calculate the numerical measure of consumers’ product evaluation expressed in each word.

Design/methodology/approach
First, all possible pairs of reviews are organized as a document to build the corpus. After that, latent topics of the traditional LDA model noted as the standard LDA model, are separated into shared and differential topics. Then, the authors associate the model with consumers’ attitudes toward each review which is distinguished as positive review and non-positive review. The product evaluation reflected in consumers’ binary attitude is expanded to each word that appeared in the corpus. Finally, a variational optimization is introduced to calculate parameters mentioned in the expanded LDA model.

Findings
The experiment’s result illustrates that the LDA model in the research noted as an expanded LDA model, can successfully assign sufficient probability with words related to products attributes or consumers’ product evaluation. Compared with the standard LDA model, the expanded model intended to assign higher probability with words, which have a higher ranking within each topic. Besides, the expanded model also has higher precision on the prediction set, which shows that breaking down the topics into two categories fits better on the data set than the standard LDA model. The product evaluation of each word is calculated by the expanded model and depicted at the end of the experiment.

Originality/value
This research provides a new method to calculate consumers’ product evaluation from reviews in the level of words. Words may be used to describe product attributes or consumers’ experiences in reviews. Assigning words with numerical measures can analyze consumers’ products evaluation quantitatively. Besides, words are labeled themselves, they can also be ranked if a numerical measure is given. Online retailers can benefit from the result for label choosing, advertising or product recommendation.
How Mercedes-Benz addresses digital transformation using Holacracy
Authors: Ackermann Malte , Schell Sabrina , Kopp Susanne 
Published: September 2021

PurposeFirms are challenged by digital transformation, as their organizational design is not up to par. Mercedes-Benz.io, a 100% subsidiary of Mercedes-Benz AG Daimler group, employs Holacracy, a self-management framework that abolishes traditional hierarchies in order to be more responsive to changes. This paper aims to explore how Mercedes-Benz.io utilizes Holacracy in order to address the challenges posed by digital transformation.Design/methodology/approachUsing qualitative expert interviews, the authors show that organizational life becomes more meaningful but also more engaging and demanding. The authors highlight that agile principles can be embedded in the organizational structure, a strong contrast to conventional management design. Decision-making authority and accountability is decentralized toward employees who face operational realities. This fosters commitment but might prolong the decision process. Leadership seems to be fairly contextual, and career paths are fundamentally different; development avenues are rather functional.FindingsThe authors conclude that Holacracy seems suitable for industries where the need for adaptability outweighs the need for reliability. It leads to increased transparency and accountability but is not a ready-made solution and requires ample resources.Originality/valueThis study is one of the first that qualitatively assess the changes, implications and outcomes of organizations that employ Holacracy.
Partnering for UN SDG #17: a social marketing partnership model to scale up and accelerate change
Authors: Duane Sinead , Duane Sinead , Domegan Christine , Bunting Brendan 
Published: September 2021

Purpose
The United Nations (UN) 17 Sustainable Development Goals (SDG) places partnerships as a vital mechanism, which strengthens the implementation of change strategies. The SDG targets are ambitious; acknowledging the interconnected multifaceted issues that are currently facing society. Similarly, social marketing thought is transitioning to embrace systemic change strategies, realising no one organisation can have an impact on the emerging grand challenges. Partnerships are the 5th P in the social marketing mix, however, partnerships is also a nebulous term which has been criticised for lacking theoretical development. This study aims to answer the call from both the UN and social marketing community for further research to guide the development and implementation of impactful transformative partnerships.

Design/methodology/approach
A robust mixed method approach to develop and test a social marketing partnership model is presented. Trust and relationship commitment are at the forefront of successful partnership exchanges. Morgan and Hunt’s (1994) trust and relationship commitment model is extended into the social marketing domain.

Findings
The findings validate Hasting’s (2003) call for social marketers to listen to their commercial marketing counterparts, positioning trust and commitment as essential to change strategies. As the degree of complexities in the multifaceted world continues to accelerate, partnerships for change (UN SDG #17) will pay off, driving more effective and smarter collaborations amongst a diverse range of stakeholders at different levels in different networks. Partnerships will elevate social marketing to deliver systemic transformation for complex problems with far reaching collective and sustainable consequences.

Research limitations/implications
With trust/mistrust critical to successful exchanges and exchange central to social marketing, quantitative measurement of the antecedents to and outcomes of partnerships can inform the evaluation, impact and management of social marketing interventions.

Practical implications
Three contributions are made, which support the selection, implementation and evaluation of social marketing partnerships. Key social marketing partnership characteristics are operationalised supporting the partnership selection process. Measurement scales are developed to assist in evaluating partnership relationships over time. The model is empirically tested to investigate the relationships between key mediating variables of social marketing partnerships.

Originality/value
This paper presents a validated 5th P Partnership model for social marketers, accelerating social marketing’s capacities to deliver systemic transformation for complex problems with far reaching collective and sustainable consequences and UN SDG #17.

PurposeFirst, the authors analyze the key problems faced by the protection of digital library readers' data privacy and behavior privacy. Second, the authors introduce the characteristics of all kinds of existing approaches to privacy protection and their application limitations in the protection of readers' data privacy and behavior privacy. Lastly, the authors compare the advantages and disadvantages of each kind of existing approaches in terms of security, efficiency, accuracy and practicality and analyze the challenges faced by the protection of digital library reader privacy.Design/methodology/approachIn this paper, the authors review a number of research achievements relevant to privacy protection and analyze and evaluate the application limitations of them in the reader privacy protection of a digital library, consequently, establishing the constraints that an ideal approach to library reader privacy protection should meet, so as to provide references for the follow-up research of the problem.FindingsAs a result, the authors conclude that an ideal approach to reader privacy protection should be able to comprehensively improve the security of all kinds of readers' privacy information on the untrusted server-side as a whole, under the premise of not changing the architecture, efficiency, accuracy and practicality of a digital library system.Originality/valueAlong with the rapid development of new network technologies, such as cloud computing, the server-side of a digital library is becoming more and more untrustworthy, thereby, posing a serious threat to the privacy of library readers. In fact, the problem of reader privacy has become one of the important obstacles to the further development and application of digital libraries.

Published: September 2021

AbstractPseudomyogenic hemangioendothelioma (PHE) is an extremely rare disease that affects mainly the young and more men than women. PHE are multicentric, locally aggressive, have low metastatic potential, and affect multiple tissue planes. Genetic aberrations are frequently detected in PHE and may play important roles in the occurrence, development, and treatment of this disease. In this study, we report a case of PHE with a novel SERPINE1‐FOSB fusion gene. The fusion introduced a strong promoter near the coding region of FOSB, resulting in overexpression of intact FOSB. Immunohistochemical analysis showed overexpression of pAKT and mTOR in tumor cells, suggesting activation of the PI3K‐AKT‐mTOR signaling pathway. The patient responded well to targeted therapy with sirolimus, an mTOR inhibitor. Our study correlated dysregulation of a specific signaling pathway and the effectiveness of a targeted therapy to a specific genetic aberration. This information may be useful for future investigations of targeted therapeutics and provide a potential predictive biomarker for therapeutic effectiveness in PHE cases.
Selection on growth rate and local adaptation drive genomic adaptation during experimental range expansions in the protistTetrahymena thermophila
Authors: Moerman Felix , Fronhofer Emanuel A. , Altermatt Florian , Wagner Andreas 
Published: September 2021

AbstractPopulations that expand their range can undergo rapid evolutionary adaptation of life‐history traits, dispersal behaviour and adaptation to the local environment. Such adaptation may be aided or hindered by sexual reproduction, depending on the context.However, few empirical and experimental studies have investigated the genetic basis of adaptive evolution during range expansions. Even less attention has been given to the question how sexual reproduction may modulate such adaptive evolution during range expansions.We here studied genomic adaptation during experimental range expansions of the protistTetrahymena thermophilain landscapes with a uniform environment or a pH gradient. Specifically, we investigated two aspects of genomic adaptation during range expansion. First, we investigated adaptive genetic change in terms of the underlying numbers of allele frequency changes from standing genetic variation andde novovariants. We focused on how sexual reproduction may alter this adaptive genetic change. Second, we identified genes subject to selection caused by the expanding range itself, and directional selection due to the presence or absence of the pH gradient. We focused this analysis on alleles with large frequency changes that occurred in parallel in more than one population to identify the most likely candidate targets of selection.We found that sexual reproduction altered adaptive genetic change both in terms ofde novovariants and standing genetic variation. However, sexual reproduction affected allele frequency changes in standing genetic variation only in the absence of long‐distance gene flow. Adaptation to the range expansion affected genes involved in cell divisions and DNA repair, whereas adaptation to the pH gradient additionally affected genes involved in ion balance and oxidoreductase reactions. These genetic changes may result from selection on growth and adaptation to low pH.In the absence of gene flow, sexual reproduction may have aided genetic adaptation. Gene flow may have swamped expanding populations with maladapted alleles, thus reducing the extent of evolutionary adaptation during range expansion. Sexual reproduction also altered the genetic basis of adaptation in our evolving populations viade novovariants, possibly by purging deleterious mutations or by revealing fitness benefits of rare genetic variants.

SummaryBacterial wilt, caused by the Ralstonia solanacearum, can infect several economically important crops. However, the management strategies available to control this disease are limited. Plant growth‐promoting rhizobacteria (PGPR) have been considered promising biocontrol agents. In this study, Bacillus amyloliquefaciens strain Cas02 was isolated from the rhizosphere soil of healthy tobacco plants and evaluated for its effect on plant growth promotion and bacterial wilt suppression. Strain Cas02 exhibited several growth‐promoting–related features including siderophore production, cellulase activity, protease activity, ammonia production and catalase activity. Moreover, strain Cas02 showed a significant inhibitory growth effect on R. solanacearum, and its active substances were separated and identified to be macrolactin A and macrolactin W by HPLC‐DAD‐ESI‐MS/MS. Both greenhouse and field experiments demonstrated a good performance of Cas02 in plant growth promotion and bacterial wilt suppression. To explore the underlying genetic mechanisms, complete genome sequencing was performed and the gene clusters responsible for antibacterial metabolites expression were identified. Overall, these findings suggest that the strain Cas02 could be a potential biocontrol agent in bacterial wilt management and a source of antimicrobial compounds for further exploitation.

AbstractAging has many effects on the female reproductive system, among which decreased oocyte quality and impaired embryo developmental potential are the most important factors affecting female fertility. However, the mechanisms underlying oocyte aging are not yet fully understood. Here, we selected normal reproductively aging female mice and constructed a protein expression profile of metaphase II (MII) oocytes from three age groups. A total of 187 differentially expressed (DE) proteins were identified, and bioinformatics analyses showed that these DE proteins were highly enriched in RNA splicing. Next, RNA‐seq was performed on 2‐cell embryos from these three age groups, and splicing analysis showed that a large number of splicing events and genes were discovered at this stage. Differentially spliced genes (DSGs) in the two reproductively aging groups versus the younger group were enriched in biological processes related to DNA damage repair/response. Binding motif analysis suggested that PUF60 might be one of the core splicing factors causing a decline in DNA repair capacity in the subsequent development of oocytes from reproductively aging mice, and changing the splicing pattern of its potential downstream DSG Cdk9 could partially mimic phenotypes in the reproductively aging groups. Taken together, our study suggested that the abnormal expression of splicing regulation proteins in aged MII oocytes would affect the splicing of nascent RNA after zygotic genome activation in 2‐cell embryos, leading to the production of abnormally spliced transcripts of some key genes associated with DNA damage repair/response, thus affecting the developmental potential of aged oocytes.

Published: September 2021

AbstractBackground and ObjectivesPrescription opioid (PO) use disorder is a national public health crisis. Distress tolerance and alexithymia are two separate but related components of emotion regulation that are known to impact substance use disorders. No studies to date, however, have examined the role of distress tolerance and alexithymia in PO use disorder. Thus, the current study examined the association between distress tolerance, alexithymia, and specific motivations for PO use.MethodsParticipants were non‐treatment‐seeking individuals with current PO use disorder (N = 81; average age = 35.0). Assessments included the Distress Tolerance Scale, Toronto Alexithymia Scale, and the Inventory of Drug Taking Situations.ResultsThe findings indicate that distress tolerance mediated the association between alexithymia and PO use in negative situations. Specifically, distress tolerance mediated the association between alexithymia and unpleasant emotions, testing personal control, and conflict with others.Conclusions and Scientific SignificanceThe results provide novel information regarding emotional states that may contribute to PO use and are malleable intervention targets. Additionally, this study adds to existing literature exploring the relationship between distress tolerance and substance use and is the first to expand upon the connection between alexithymia and distress tolerance in an opioid‐using population. Implications for clinical practice and future research are discussed.
Observational Equivalence in Explaining Attitude Change: Have White Racial Attitudes Genuinely Changed?
Authors: Engelhardt Andrew M. 
Published: September 2021

AbstractUnderstanding when and why White racial attitudes change is important for understanding their politics. Critically, surveys reveal Whites’ views of Black Americans have been changing recently, an important result given conventional wisdom that these are stable orientations. I test four possible explanations for these shifting views: genuine attitude change, social desirability, partisan expressive responding, and changing racial attitude measure performance. Importantly, these explanations produce observationally equivalent survey toplines. To adjudicate between them, I use the measurement equivalence framework and examine how Whites answer the racial resentment measure. Evidence from multigroup confirmatory factor analysis models supports genuine attitude change. Substantively, this suggests these changes may have important political implications. Methodologically, it suggests partisan expressive responding may have limits, indicates social desirability pressures have not changed how Whites answer at least one racial attitude measure, and offers additional validity evidence for the racial resentment measure.
