AbstractMetacaspases are part of an evolutionarily broad family of multifunctional cysteine proteases, involved in disease and normal development. Despite the extensive study of metacaspases in the two decades since their discovery, the structure-function relationship of metacaspases remains poorly understood. Furthermore, previous studies on their function have been thwarted by the redundancy in gene copy number and potential phenotypic suppression of genetic mutations, especially in plants. Here, we have solved the X-ray crystal structure of anArabidopsis thalianatype II metacaspase (AtMCA-IIf) that belongs to a particular sub-group that does not require calcium ions for activation. Compared to crystal structures of other metacaspases and caspases, the AtMCA-IIf active site is structurally similar and poses a conundrum for the catalytic mechanism of the cysteine-histidine dyad. To study metacaspase activity in plants, we developed anin vitrochemical screen to identify small molecule metacaspase inhibitors. Several hits with a minimal thioxodihydropyrimidine-dione (TDP) structure were identified, some being specific inhibitors of AtMCA-IIf. We provide a mechanistic basis for inhibition by the TDP-containing compounds through molecular docking onto the AtMCA-IIf crystal structure. Finally, a TDP-containing compound (TDP6) was effective at inhibiting lateral root emergencein vivo, likely through the inhibition of metacaspases that are specifically expressed in the endodermal cells overlaying developing lateral root primordia. In the future, the small compound inhibitors and crystal structure of AtMCA-IIf can be used to study metacaspases in various other species, such as important human pathogens including those causing neglected diseases.

The G-CHIME model comprises six elements important to addiction recovery (growth, connectedness, hope, identity, meaning in life and empowerment). It provides a standard to against which to consider addiction recovery, having been used in this series, as well as in the design of interventions that improve well-being and strengthen recovery. In this paper, a first-hand account is presented, followed by a semi-structured e-interview with the author of the account. Narrative analysis is used to explore the account and interview through the G-CHIME model.

Findings
This paper shows that addiction recovery is a remarkable process that can be effectively explained using the G-CHIME model. The significance of each component in the model is apparent from the account and e-interview presented.

Originality/value
Each account of recovery in this series is unique, and as yet, untold.
Appearance and media popularity affecting experiential gift-giving
Authors: Chen Tser Yieth , Wu Hsueh-Ling , Tai Zhi-Cheng 
Published: January 2023

PurposeThe purpose of this study is to explore the effect of popularity appeals (appearance popularity and media popularity) on online experiential gift purchase intention based on different types of givers (close or distant givers) and different gift attributes (conspicuous or inconspicuous gifts), a novel research consideration.Design/methodology/approachThis study was conducted with two experiments and examined four hypotheses. These hypotheses were examined using a 2 × 2 between-subjects design, and a two-factorial variance analysis was conducted.FindingsThis study found that for close givers, appearance popularity appeals created a greater purchase intention than media popularity appeals. That is, gift-givers faced appearance popularity rather than media popularity, driving them to face a strong feeling of excitement for their idol worship. This finding implies that the human brand theory works.Practical implicationsThe empirical results can shed light on brand or product managers in raising the ratio of appearance popularity appeals to marketing in online experiential gift-giving. Gift marketers should accurately understand the current trends and social preferences using a database and big data analysis tools.Originality/valueThis study is the first to investigate whether the two types of popularity appeals affect gift purchase intention in online experiential gifts.
Aesthetic labour and diversity on the shopfloor: the experiences of women workers in fashion retail
Authors: Oluyadi Lydia Olakumbi , Dai Wenjin 
Published: January 2023

PurposeThis paper explores the workplace experiences of aesthetic labour among racially diverse frontline women workers in a fashion retail store.Design/methodology/approachThis qualitative study is based on an ethnographic study, drawing on findings from participant observation and interviews with frontline workers at a fashion retail store in the UK.FindingsThis paper explores how the embodiments of aesthetic labour are perpetually produced and commodified through the discipline of management in a fashion retail store. It challenges the notion of phenotypical Whiteness as the beauty standard within fashion retail and demonstrates how embodiments differ according to race. While White women are continuously scrutinised by their appearance, the aesthetic demands for women of colour tend to focus on speech and racialised bodies to provide “authentically” exotic experiences for customers. Additionally, this study highlights how the mobilisation of aesthetic labour can create work humiliation and work alienation.Research limitations/implicationsDespite this study being based on an ethnographic study at one British fashion retailer, this paper seeks to give voices to an underrepresented group by exploring the lived experiences of racially diverse women workers.Originality/valueThis paper contributes to the intersection between aesthetic labour and race from an embodiment perspective, exploring the workplace experiences of racially diverse women workers in fashion retail and how their various forms of embodiment are racialised and commodified.
How publication timelines effect the impact metrics: studying the influence of submission to first decision and submission to acceptance on impact factor and 5-year impact factor of journals
Authors: Lone Yasir Rashid , Shah Ubaid Ullah , Bhat Suhail Ahmad , Mushtaq Rabiya , Gul Sumeer 
Published: January 2023

Purpose
The purpose of the study is to analyze the impact of the Publication Timeline, i.e. Submission to First Decision and Submission to Acceptance on Journal Metrics, i.e. Impact Factor (IF) and 5-year IF.

Design/methodology/approach
Data related to the IF and 5-year IF were retrieved from Clarivate Analytics’ Journal Citation Report 2020. The Publication Timeline of each journal was ascertained through their respective websites. To attain the model fit summary, an analysis of variance (ANOVA) test was performed. Regression analysis was also performed on the models using SPSS 21 software to ascertain the nature and degree of impact the Publication Timeline (Submission to First Decision and Submission to Acceptance) has on Journal Metrics (IF and 5-year IF).

Findings
Submission to First Decision has a significant inverse relationship with both the IF and 5-year IF, whereas Submission to Acceptance has a significant direct relation with 5-year IF and an inverse but insignificant relationship with IF.

Research limitations/implications
Journals published by Springer Nature and of multidisciplinary nature have been considered for the study. Only those journals were selected that provided the information regarding the Publication Timeline, whereas those which did not provide the same, were excluded. However, new insights can be revealed if the journals published by different publishers and belonging to one particular discipline are studied.

Practical implications
The study helps to ascertain the impact of the Publication Timeline on the Impact Metrics of the journals. It can help the authors select the journals as their publishing venues considering the Publication Timeline. Publishers can also be benefitted from the findings of this study since improvisations and modifications in their Publication Timelines can positively influence the impact metrics of their respective journals.

Originality/value
The study attempts to measure the impact of the Publication Timeline on Journal Metrics using cross-sectional secondary data, by performing regression analysis. Though various studies have examined the influence of the Publication Timeline on the IF using correlation analysis, to the best of the authors’ knowledge, this study is the first of its kind to use regression analysis to check the relation, as well as the degree of impact the Publication Timeline, has on Journal Metrics.

Authors: Ying Xing 
Published: January 2023

PurposeThe purpose of this paper investigates dynamic ease distributions of clothes at bust and waist lines with different body surface angle by using a Qualisys three-dimensional motion capture system (3DMCS).Design/methodology/approachThe current method first obtain the specific markers of participants and their clothes along the bust and waist lines through 3DMCS, then using the least square method and four piecewise polynomial fitting participants and their clothes' bust and waist curves. The coordinates of the markers were tracked by the 3DMCS, while the participants under different body surface angle walked on a treadmill calculated the distances of markers coordinates to the participants' bust and waist curves. Finally, the data of samples were analyzed. It was found that the dynamic ease distributions showed different patterns at different body surface angle.FindingsThe results revealed the bust convex angle is 26.53 degrees (Specification:X3) and back slope angle is 13.96 degrees (Specification: Y1), the fluctuation of participant ease distributions on bust section was most obvious, and the maximum fluctuation value was ±20 mm and ±25 mm. The ease distributions of participant waist section fluctuated most obviously when the bust convex angle is 28.10 degrees (Specification: X5) and the back slope angle is 13.96 degrees (Specification: Y1), and the maximum fluctuation was ±30 mm and ±20 mm. The bust convex angle has the greatest influence on 1# garment, and the back slope angle has the greatest influence on 2# garment.Originality/valueCurrently, there is little information in the literature about dynamic ease distributions of garment on a different body types. This paper takes different body surface angles as the research objects to analyze the ease distributions of different clothes, the conclusion can provide reference data for 3D garment modeling and improve the authenticity of virtual garment fitting.
Coopetition and the marketing/entrepreneurship interface in an international arena
Authors: Crick James M. , Crick Dave , Ferrigno Giulio 
Published: January 2023

PurposeGuided by resource-based theory, this study unpacks the relationship between an export entrepreneurial marketing orientation (EMO) and export performance. This is undertaken by investigating quadratic effects and the moderating role of export coopetition (cooperation amongst competitors in an international arena).Design/methodology/approachSurvey responses were collected from a sample of 282 smaller-sized wine producers in Italy. This empirical context was ideal, as it hosted varying degrees of the constructs within the conceptual model. Put another way, it was suitable to test the underlying issues for theorising purposes. The hypotheses and control paths were tested through a three-step hierarchical regression analysis.FindingsAn export EMO had a non-linear (inverted U-shaped) association with export performance. Furthermore, this link was positively moderated by export coopetition. With too little of an export EMO, small enterprises might struggle to create value for their overseas customers. With too much of an export EMO, owner-managers could experience harmful performance outcomes. By cooperating with appropriate industry rivals, small companies can acquire new resources, capabilities and opportunities to help them to boost their export performance. That is, export coopetition can stabilise some of the potential dangers of employing an export EMO.Originality/valueThe empirical findings signified that an export EMO has potential dark-sides if these firm-wide behaviours are not implemented effectively. Nevertheless, cooperating with competitors in export markets can alleviate some of these concerns. Collectively, unique insights have emerged, whereby entrepreneurs are advantaged by being strategically flexible and collaborating with appropriate key stakeholders to enhance their export performance.

Authors: Yang Yueting , Hu Shaolin , Ke Ye , Zhou Runguan 
Published: January 2023

PurposeFire smoke detection in petrochemical plant can prevent fire and ensure production safety and life safety. The purpose of this paper is to solve the problem of missed detection and false detection in flame smoke detection under complex factory background.Design/methodology/approachThis paper presents a flame smoke detection algorithm based on YOLOv5. The target regression loss function (CIoU) is used to improve the missed detection and false detection in target detection and improve the model detection performance. The improved activation function avoids gradient disappearance to maintain high real-time performance of the algorithm. Data enhancement technology is used to enhance the ability of the network to extract features and improve the accuracy of the model for small target detection.FindingsBased on the actual situation of flame smoke, the loss function and activation function of YOLOv5 model are improved. Based on the improved YOLOv5 model, a flame smoke detection algorithm with generalization performance is established. The improved model is compared with SSD and YOLOv4-tiny. The accuracy of the improved YOLOv5 model can reach 99.5%, which achieves a more accurate detection effect on flame smoke. The improved network model is superior to the existing methods in running time and accuracy.Originality/valueAiming at the actual particularity of flame smoke detection, an improved flame smoke detection network model based on YOLOv5 is established. The purpose of optimizing the model is achieved by improving the loss function, and the activation function with stronger nonlinear ability is combined to avoid over-fitting of the network. This method is helpful to improve the problems of missed detection and false detection in flame smoke detection and can be further extended to pedestrian target detection and vehicle running recognition.
Understanding performance measurement and management as a social system: towards a theoretical framework
Authors: Mackenzie Helen , Bititci Umit S. 
Published: January 2023

PurposeThe conceptual foundations of performance measurement and management (PMM) are predominantly rooted in control systems research. However, the appropriateness of this paradigm for volatile and uncertain environments has been questioned. This paper explores whether grounding PMM in social systems theory and viewing uncertainty from an organisational behaviour perspective provides new insights into the PMM theory–practice gap.Design/methodology/approachA framework, rooted in social systems theory and practice theory, is created that describes how organisational behaviour shapes the social processes associated with organisational change. Semi-structured interviews of 35 people from 16 organisations coupled with thematic analysis are employed to identify the organisational behavioural characteristics that influence how PMM is executed in practice. PMM is then reconceptualised from the perspective of this social systems-based framework.FindingsThis investigation proposes (1) performance management is concerned with elements of PMM-related practices open to flexible interpretation by human agents that change the effectiveness of organisational practices, whereas performance measurement is concerned with elements of PMM-related practices not open to interpretation but deliberately reproduced to provide a consistent comparison with the past; (2) the purpose of PMM should be to achieve organisational effectiveness (OE) and (3) the mechanisms underlying performance management and performance measurement are social intervention and embeddedness, respectively.Originality/valueThis first social systems perspective of PMM advances the development of PMM's theoretical foundations by providing a behaviour-based interpretation of, and framework for, PMM-mediated organisational change. This competing approach has strong links to practice.
Sentiment, we-talk and engagement on social media: insights from Twitter data mining on the US presidential elections 2020
Authors: Hagemann Linus , Abramova Olga 
Published: January 2023

PurposeGiven inconsistent results in prior studies, this paper applies the dual process theory to investigate what social media messages yield audience engagement during a political event. It tests how affective cues (emotional valence, intensity and collective self-representation) and cognitive cues (insight, causation, certainty and discrepancy) contribute to public engagement.Design/methodology/approachThe authors created a dataset of more than three million tweets during the 2020 United States (US) presidential elections. Affective and cognitive cues were assessed via sentiment analysis. The hypotheses were tested in negative binomial regressions. The authors also scrutinized a subsample of far-famed Twitter users. The final dataset, scraping code, preprocessing and analysis are available in an open repository.FindingsThe authors found the prominence of both affective and cognitive cues. For the overall sample, negativity bias was registered, and the tweet’s emotionality was negatively related to engagement. In contrast, in the sub-sample of tweets from famous users, emotionally charged content produced higher engagement. The role of sentiment decreases when the number of followers grows and ultimately becomes insignificant for Twitter participants with many followers. Collective self-representation (“we-talk”) is consistently associated with more likes, comments and retweets in the overall sample and subsamples.Originality/valueThe authors expand the dominating one-sided perspective to social media message processing focused on the peripheral route and hence affective cues. Leaning on the dual process theory, the authors shed light on the effectiveness of both affective (peripheral route) and cognitive (central route) cues on information appeal and dissemination on Twitter during a political event. The popularity of the tweet’s author moderates these relationships.
When in Rome, do as the Romans do: can international marketing adaptation improve the association between servitization and profitability?
Authors: Guedes Maria João , Fernandes Crespo Nuno , Patel Pankaj C. 
Published: January 2023

Purpose
Building on contingency theory, this paper aims to investigate the extent to which the “4Ps international adaptation strategy” and internationalization intensity shape the servitization–profitability relationship.

Design/methodology/approach
The authors use primary (survey) and secondary (archival) data to perform multiple regression analysis.

Findings
The results indicate a positive relationship between servitization and profitability, and international intensity strengthens this association. The effects, however, are not consistent across the 4Ps – the price international adaptation strategy strengthens the positive relationship between servitization and profitability, while product and place international adaptation strategies weaken that relationship.

Practical implications
The findings have implications for the role of international intensity and the 4Ps in the marketing servitization context.

Originality/value
The study provides guidance for small firms in realizing higher performance by leveraging the 4Ps in the servitization context. Counter to expectations, placement and product lead to lower performance with increasing servitization, whereas price strengthens this relationship. The study adds to the international industrial management and marketing literature, providing evidence that contingency factors such as international marketing mix adaptation/standardization strategies moderate the servitization–profitability relationship.
Enterprise social media and organizational learning capability: mediated moderation effect of social capital and informal learning
Authors: Sharma Anshu , Bhatnagar Jyotsna , Jaiswal Mahadeo , Thite Mohan 
Published: January 2023

PurposeWith the increasing prevalence of social media in everyday life, scholars have argued the need of exploring enterprise social media (ESM) for workplace outcomes. This study investigates the relationship between ESM use and organizational learning capability (OLC) by focusing on the mediating role of informal learning (INFL) and the moderating role of social capital (SC).Design/methodology/approachThe paper developed and tested a mediated moderated model explaining the impact of ESM on OLC. The study used temporally separated data of 281 respondents collected in two waves from firms in India that use organizationally facilitated ESM platforms for internal workplace communication.FindingsAn analysis of temporally separated two-wave data indicates that INFL mediates the relationship between ESM use and OLC. Also, SC is found to moderate the effect of ESM use on INFL, and INFL mediated the moderation effect of SC on relationship between ESM use and OLC such that the relationship will be stronger when employees have a higher rather than lower level of SC.Research limitations/implicationsThe study theoretically contributes and extends the literature on ESM and learning in organizations. The study provides important practical implications to support and institutionalize learning at work. The results of the study provide evidence that ESM are not just networking tools but a platform for learning. Findings of the study suggest that ESM can be one such tool to promote and capture employee INFL. The results also show that SC plays a critical role in predicting the extent to which employees learn informally using ESM, thereby building OLC. This result suggests that organizations should make conscious and concerted efforts to build employee SC. The above findings also have interesting implications for learning and development (L&D) and information technology (IT) managers who wish to implement technology for collaborative purposes.Originality/valueAddressing the underlying processes that explain how ESM positively influence OLC was highlighted as a critical research gap that needs attention. The paper is novel in its approach as it provides empirical evidence for the relationship between ESM and its impact on employee outcomes, an area pertinent in today's digital economy, however, received sparse attention by management scholars so far. It also provides empirical grounds toward a meaningful shift in the social media discourse – transition from being traditionally viewed primarily as “a networking platform” to “a learning platform.”
