Cytokinin signalling regulates two-stage inflorescence arrest in Arabidopsis

Published: January 2022

ABSTRACTTo maximise their reproductive success, flowering plants must correctly time their entry into and exit from the reproductive phase (flowering). While much is known about the mechanisms that regulate the initiation of flowering, the regulation of end-of-flowering remains largely uncharacterised. End-of-flowering in Arabidopsis thaliana consists of the quasi-synchronous arrest of individual inflorescences, but it is unclear how this arrest is correctly timed with respect to environmental stimuli and ongoing reproductive success. Here we show that Arabidopsis inflorescence arrest is a complex developmental phenomenon which includes a decline in size and cessation of activity in the inflorescence meristem (IM), coupled with a separable developmental arrest in all unopened floral primordia (floral arrest); these events occur well before the visible arrest of the inflorescence. We show that global removal of inflorescences can delay both IM arrest and floral arrest, but that local fruit removal only delays floral arrest, emphasising the separability of these processes. We test a role for cytokinin in regulating inflorescence arrest, and find that cytokinin treatment can delay arrest. We further show that gain-of-function cytokinin receptor hypersensitive mutants can delay floral arrest, and also IM arrest, depending on the expression pattern of the receptor; conversely, loss-of-function mutants prevent extension of flowering in response to inflorescence removal. Collectively, our data suggest that the dilution of cytokinin among an increasing number of sink organs leads to end-of-flowering in Arabidopsis by triggering IM and floral arrest, conversely meaning that a lack of reproductive success can homeostatically extend flowering in compensation.

ABSTRACTRecombination is critical both for accelerating adaptation and for the purging of deleterious mutations. Chromosomal inversions can act as recombination modifiers that suppress local recombination and, thus, are predicted to accumulate such mutations. In this study, we investigated patterns of recombination, transposable element abundance and coding sequence evolution across the genomes of 1,445 individuals from three sunflower species, as well as within nine inversions segregating within species. We also analyzed the effects of inversion genotypes on 87 phenotypic traits to test for overdominance. We found significant negative correlations of long terminal repeat retrotransposon abundance and deleterious mutations with recombination rates across the genome in all three species. However, we failed to detect an increase in these features in the inversions, except for a modest increase in the proportion of stop codon mutations in several very large or rare inversions. Moreover, there was little evidence of phenotypic overdominance in inversion heterozygotes, consistent with observations of minimal deleterious load. On the other hand, significantly greater load was observed for inversions in populations polymorphic for a given inversion compared to populations monomorphic for one of the arrangements, suggesting that the local state of inversion polymorphism affects deleterious load. These seemingly contradictory results can be explained by the geographic structuring and consequent excess homozygosity of inversions in wild sunflowers. Inversions contributing to local adaptation often exhibit geographic structure; such inversions represent ideal recombination modifiers, acting to facilitate adaptive divergence with gene flow, while largely averting the accumulation of deleterious mutations due to recombination suppression.
Transbilayer Coupling of Lipids in Cells Investigated by Imaging Fluorescence Correlation Spectroscopy

Published: January 2022

ABSTRACTPlasma membrane hosts numerous receptors, sensors, and ion channels involved in cellular signaling. Phase separation of the plasma membrane is emerging as a key biophysical regulator of signaling reactions in multiple physiological and pathological contexts. There is much evidence that plasma membrane composition supports the co-existence liquid-ordered (Lo) and liquid-disordered (Ld) phases or domains at physiological conditions. However, this phase/domain separation is nanoscopic and transient in live cells. It is recently proposed that transbilayer coupling between the inner and outer leaflets of the plasma membrane is driven by their asymmetric lipid distribution and by dynamic cytoskeleton-lipid composites that contribute to the formation and transience of Lo/Ld phase separation in live cells. In this Perspective, we highlight new approaches to investigate how transbilayer coupling may influence phase separation. For quantitative evaluation of the impact of these interactions, we introduce an experimental strategy centered around Imaging Fluorescence Correlation Spectroscopy (ImFCS), which measures membrane diffusion with very high precision. To demonstrate this strategy we choose two well-established model systems for transbilayer interactions: crosslinking by multivalent antigen of immunoglobulin E bound to receptor FcεRI, and crosslinking by cholera toxin B of GM1 gangliosides. We discuss emerging methods to systematically perturb membrane lipid composition, particularly exchange of outer leaflet lipids with exogenous lipids using methyl alpha cyclodextrin. These selective perturbations may be quantitatively evaluated with ImFCS and other high-resolution biophysical tools to discover novel principles of lipid-mediated phase separation in live cells in the context of their pathophysiological relevance.
Q&A participation and behavioral patterns on academic social networking sites: a comparative study of academic, corporate and government institutions on ResearchGate
Authors: Yan Weiwei , Deng Wanying , Sun Xiaorui , Wang Zihao 
Published: January 2022

PurposeThis paper aims to explore question and answer (Q&A) participation and behavioral patterns on academic social networking sites (ASNSs) from the perspective of multiple subjects such as academic, corporate and government institutions.Design/methodology/approachFocused on the Q&A service of ASNSs, this study chooses ResearchGate (RG) as the target ASNS and collects a large-scale data set from it, involving a sample of users and a Q&A sample about academic, corporate and government institutions. First, it studies the law of Q&A participation and the distribution of the type of user according to the sample of users. Second, it compares question-asking behavior and question-answering behavior stimulated by questions among the three types of institutions based on the Q&A sample. Finally, it discusses the Q&A participation and behavioral patterns of the three types of institutions in academic Q&A exchanges with full consideration of institutional attributes, and provides some suggestions for institutions and ASNSs.FindingsThe results show that these three types of institutions generally have a low level of participation in the Q&A service of RG, and the numbers of questions and answers proposed by institutional users conform to the power-law distribution. There are differences in Q&A participation and Q&A behavioral patterns among academic, corporate and government institutions. Government and academic institutions have more users participating in the Q&A service and their users are more willing to ask questions, while corporate institutions have fewer users who participate in the Q&A service and their users are inclined to provide answers. Questions from corporate institutions attract much more attention than those from the other two types of institutions.Originality/valueThis study reveals and compares the Q&A participation and the behavioral patterns of the three types of institutions in academic Q&A, thus deepening the understanding of the attributes of institutions in the academic information exchange context. In practice, the results can help guide different institutions to use the Q&A service of ASNSs more effectively and help ASNSs to better optimize their Q&A service.

Authors: Zhu Zhangxiang , Zhang Xiaoqian , Wang Jing , Chen Sixuan 
Published: January 2022

PurposeThe study aims to explore the effects of photograph quality on visual appeal, perceived usefulness and viewers' travel intentions from rational and irrational perspectives while simultaneously providing some references for the management and marketing of tourism destinations.Design/methodology/approachThe study comprises four experiments combined with structural equation modeling to explore the influence mechanism of photograph quality on travel intentions.Findings(1) Higher-quality photographs offer greater visual appeal and perceived usefulness to viewers, and these relationships are moderated by the photograph source. Specifically, high-quality photographs generated by other tourists have more visual appeal and perceived usefulness to viewers. However, there are no significant differences in the impact of low-quality photographs generated by other tourists and destination marketing organizations (DMOs) on visual appeal and perceived usefulness. (2) Visual appeal and perceived usefulness significantly affect viewers' travel intentions, and visual appeal positively affects perceived usefulness. (3) Travel experience positively moderates the effects of visual appeal and perceived usefulness on viewers' travel intentions.Originality/valueThe study explores the effects of the visual appeal (irrational factor) and perceived usefulness (rational factor) associated with photograph quality on viewers' travel intentions. Photograph source and travel experiences have moderating effects on this influence mechanism.

Published: January 2022

PurposeThis study examines the perceptions of interested stakeholders on the factors affecting the use of data analytics (DA) in financial statement audits. Response letters submitted by stakeholders of the auditing services to the International Auditing and Assurance Standards Board's (IAASB) Data Analytics Working Group (DAWG) served as sources for analysis.Design/methodology/approachThe modified information technology audit model was used as a framework to perform a direct content analysis of all the 50 response letters submitted to the DAWG.FindingsThe analysis showed that a range of attributes, such as the usefulness of DA in auditing, authoritative guidance (auditing standards), data reliability and quality, auditors' skills, clients' factors and costs, were the factors perceived by stakeholders to be affecting the use of DA in external auditing.Research limitations/implicationsThis study is subjected to the limitations inherent to all content analysis studies. Nonetheless, the findings offer additional insights about potential factors affecting the adoption of DA in audit practices.Originality/valueThe data noted in the published statements highlighted the perceptions of a range of stakeholders with regards to the factors affecting the use of DA in auditing.
Financial inclusion through Kiosk-based banking services: a study with reference to business correspondent models in the state of Kerala
Authors: Shafi M.K Muhammed , Reddy M. Ravindar 
Published: January 2022

PurposeThe paper aims to study the outreach and performance of business correspondent (BC) models, which are implemented as a subsidiary agent of banks to accelerate the financial inclusion (FI) mission in India. In this regard, the study illustrates BC's products and services rendered to customers, forms of delivery channels and BC's view on banking services and Kiosk-based BC programs.Design/methodology/approachThe current paper is an empirical study based on surveying 200 Kiosk-based BCs working in the state of Kerala. After the preliminary screening analysis of the data with outlier deletion, removal of missing values and normality test, both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were executed followed by reliability test, convergent and discriminant validity tests. Covariance-based structural equation modeling (CBSEM) was performed for CFA and inferential tests were carried out by using statistical package for the social sciences (SPSS) and analysis of a moment structures (AMOS) and Eviews.FindingsChiefly, eight operational forms of BCs were found from the field survey. Hypothetical tests show the significant impact of the serviceability of banks on BC's profitability. Validity tests such as average variance extracted (AVE), composite reliability (CR), maximum shared variance (MSV) and average shared variance (ASV) were established after the removal of the cross-loaded items of the questionnaire from the rotated component matrix. BCs perform main banking services especially bank account opening facility and Akshaya E-Centers are widely used for this model as Kiosk banking in the surveyed state.Originality/valueSo far, no study has encompassed empirical research on performance analysis and outreach of the BC model in the state of Kerala where this BC model well functions. Since the study is a novel form of banking channelization for FI, the study can contribute to understanding the further feasibility and future dimension of the model based on experimental views of BCs.

Authors: Zhao Yue , Zhan Jing 
Published: January 2022

PurposeThe study aims to analyze how occupational stigma consciousness affects workplace deviant behavior.Design/methodology/approachThe authors used a time-lagged research design. Data from 354 riders working on the platform were gathered, and multiple regression and bootstrapping were used to test the hypotheses.FindingsBased on the ego depletion theory and resource perspective, the study explores the relationship between the occupational stigma consciousness and workplace deviant behavior of platform riders in China. Occupational stigma consciousness promotes workplace deviant behavior; self-depletion mediates the positive relationship between occupational stigma consciousness and workplace deviant behavior and workplace mindfulness exerts a negative moderating effect on the relationship between occupational stigma consciousness and self-depletion.Originality/valueThe study provides a resource perspective to understand how occupational stigma consciousness is related to workplace deviant behavior and how workplace mindfulness alleviates resource depletion caused by occupational stigma consciousness. The research results provide practical information for managers to reduce deviant behavior, which helps to promote riders' performance on the platform.
The multiple mediating effects of Korean workers’ perception of the fourth industrial revolution, career attitudes and future learning intent
Authors: Moon Hanna , Hong Sungpyo 
Published: January 2022

Purpose
This study aims at analyzing the impact of perceptions of the fourth industrial revolution (crisis and opportunity) in the relationship between workers’ career attitudes and future learning intentions.

Design/methodology/approach
This study analyzed the multiple mediating effect of the perception of the fourth industrial revolution in the relationship between career attitudes and future learning intention using data of 305 Korean workers. As career attitude variables, boundaryless and protean career orientation variables were used, and perception of the fourth industrial revolution was analyzed (opportunity and crisis perception).

Findings
Both workers’ boundaryless career orientation and protean career orientation influenced future learning intention through the perception of opportunity for the fourth industrial revolution. This result suggested that flexible career attitudes positively recognized the changes of the fourth industrial revolution and had an effect on promoting attitude toward future learning.

Research limitations/implications
The study confirmed that workers’ flexible career attitudes could promote perception of opportunity rather than crisis in changing situation and strengthen their intention to prepare for the future by mediating this perception. These results suggest that lifelong learning and competency development can be reinforced by facilitating perception of an opportunities for external change for individual career development.

Originality/value
Insights for personal career development were provided by analyzing the relationship between flexible career attitudes, which are increasing in importance in the modern society, and perceptions of changes in external environment.
Taking off the rose-colored glasses: the influence of crises on employee relationship management
Authors: Diers-Lawson Audra , Collins Lorraine 
Published: January 2022

PurposeThe central aim of this research is to deepen the analysis of the influence that crises have on employee relations by using the stakeholder relationship management model (SRM) to analyze organizational employee relationship management (OERM).Design/methodology/approachThis study uses a questionnaire distributed in two organizations (UK-based public sector and private sector) that were experiencing a crisis at the time of data collection. Respondents identified whether they believed the organization was in crisis, if they defined it as in crisis classified what type of crisis it was, and then responded to questions about their relationship to the organization, the organization's post crisis stability and their own behavioral intentions.FindingsThe findings verify the applicability of the SRM in employee relations with three critical findings: (1) employees with higher income in the private sector were significantly less likely to believe their organization was in crisis; (2) the more ambiguous the blame for the crisis, the greater the damage on the relationship between organizations and employees; and (3) collective sensemaking in organizations is essential, but less likely when a crisis has damaged the relationship between employees and organizations.Originality/valueIn the last 40 years ofEmployee Relations, the role of crisis in influencing OERM has not been meaningfully explored in the journal. Therefore, the piece makes an original contribution.
Food waste generation in a university and the handling efficiency of a university catering facility-scale automatic collection system
Authors: Mui Kwok Wai , Wong Ling Tim , Tsang Tsz-Wun , Chiu Yin Hei , Lai Kai-Wing 
Published: January 2022

Purpose
This study aims to evaluate the generation of food waste in a university and the handling efficiency of an automatic waste collection system.

Design/methodology/approach
The quantity of food waste generated and collected from a university canteen was surveyed. The food waste handling efficiencies using manual collection strategy and automated food waste collection system were determined by the density of food waste. Life-cycle costing analysis was done to evaluate the economic impacts of various food waste collection methods.

Findings
As compared with the manual collection approach, the automatic system can improve the food waste handling efficiency by 30% (from 0.01 to 0.007 bin kg−1) and reduce the water use by 20% (from 0.512 to 0.406 L kg−1); however, it also consumes 4.4 times more energy (from 0.005 to 0.027 kWh kg−1). Under ideal system operation, the 10-year cost of food waste collection was significantly reduced from $3.45 kg−1 in the manual collection to $1.79 kg−1, and the payback period of the system collection was 1.9 years without discount.

Practical implications
The outcomes of this study show that an automatic food waste collection system is feasible, and it is recommended for small- and medium-sized catering facilities (e.g. canteens and food courts) to improve food waste handling efficiency. This study also provides useful reference data of automatic food waste collection systems for planning food waste management programs for catering facilities.

Originality/value
To the best of the authors’ knowledge, this is the first study to evaluate the waste handling efficiency, operational expenditure and life-cycle cost of a small-scale automatic food waste collection system.
Key performance indicators for measuring performance of facilities management services in hotel buildings: a study from Sri Lanka
Authors: Dasandara Miyami , Dissanayake Piumi , Fernando Devsayura Jude 
Published: January 2022

PurposeThe concept of facilities management (FM) has been acknowledged as a novel avenue brought in to ensure productivity and customer satisfaction in the Sri Lankan hotel industry. Accordingly, performance measurement (PM) has become a crucial entity, where key performance indicators (KPIs) have become the most important instruments of PM in determining how well these FM services are performing. Unfortunately, nowadays, the service quality of hotel buildings has significantly retreated due to the absence of a proper PM system with relevant KPIs. Thus, the purpose of this study was to identify relevant KPIs to measure the performance of the FM services in Sri Lankan hotel buildings.Design/methodology/approachA mixed approach was used to conduct this study. Data were gathered through expert interviews and an expert survey. The expert interviews were conducted to identify the relevancy of KPIs that are discovered through literature review to the Sri Lankan context, and the expert survey was conducted to identify their level of importance. Collected data were analysed using content and statistical data analysis methods.FindingsEmpirical findings revealed that a PM system with relevant KPIs can be identified as a crucial requirement for FM services in hotel buildings in Sri Lanka to meet the customer needs successfully. Adequate and relevant KPIs are significantly vital for an effective PM system for FM services. Thus, ultimately, 68 most important KPIs have been captured amongst the generally identified KPIs, which can be used in developing a proper PM system to measure the performance of FM services in hotel buildings.Originality/valueThe previous studies have just focused on the PM in FM services in a general manner where a significant dearth in existing knowledge can be identified when it comes to exploring relevant KPIs for an effective PM system to be implemented in hotel buildings in Sri Lanka to measure the performance of FM services. Accordingly, the current study unveils the most important KPIs, which can be used in measuring the performance of FM services in hotel buildings. The study recommends the use of a proper PM system with identified KPIs by respective industry practitioners to enrich the performance of FM services in hotel buildings in Sri Lanka and thereby achieve the ultimate goals successfully.
