AbstractMeiosis is a specialized cell division that halves the number of chromosomes in two consecutive rounds of chromosome segregation. In angiosperm plants is meiosis followed by mitotic divisions to form rudimentary haploid gametophytes. In Arabidopsis, termination of meiosis and transition to gametophytic development is governed by TDM1 and SMG7 that mediate inhibition of translation. Mutants deficient in this mechanism do not form tetrads, but instead undergo multiple cycles of aberrant nuclear divisions, that are likely caused by the failure to downregulate cyclin dependent kinases during meiotic exit. A suppressor screen to identify genes that contribute to meiotic exit uncovered a mutation in CDKD;3 that alleviates meiotic defects insmg7deficient plants. The CDKD;3 deficiency prevents aberrant meiotic divisions observed insmg7mutants, or delays their onset after initiation of cytokinesis, which permits formation of functional microspores. Although CDKD;3 acts as an activator of CDKA;1, the main cyclin dependent kinase that regulates meiosis,cdkd;3mutation appears to promote meiotic exit independently of CDKA;1. Furthermore, analysis of CDKD;3 interactome revealed enrichment for proteins implicated in cytokinesis suggesting a more complex function of CDKD;3 in cell cycle regulation.

Published: August 2022

PurposeThe purpose of the present study was to design an axial coding pattern for customer knowledge management (CKM) to identify the conditions affecting it from the perspective of experts in public university libraries.Design/methodology/approachThe current study used a qualitative approach. To collect and analyze data, the grounded theory method with a three-stage strategy of open, axial and selective coding was employed. The research instrument was a semi-structured in-depth interview and the data were categorized using MAXQDA 10 software. The sample of the study consisted of 26 experts from Iranian public universities who were selected through a combined targeted non-random sampling procedure (targeted and snowball). The necessary data were obtained through specialized interviews with 9 faculty members and 17 managers of public university libraries.FindingsIn the present study, 106 open coding, 35 axial concepts, and 16 selective general categories were identified as the conditions affecting CKM development in academic libraries in the form of causal conditions, intervening conditions, strategies conditions, context conditions, and consequences conditions around the core layer of CKM development. The identification of these conditions led to the development of a paradigmatic pattern for the research.Originality/valueThere is no record of research on developing empirical studies in libraries using an analysis of the conditions affecting CKM development in the form of an axial coding pattern. The present research contributed to closing this research gap. The axial coding pattern proposed in this study can serve as a guide for implementing CKM in academic libraries as well as increasing customer loyalty.

Authors: Pérez-Pérez Lucía , Berlanga Inmaculada , Victoria Juan Salvador 
Published: August 2022

PurposeThe study aims to establish that a humanistic model is a necessary context for efficient employer branding (EB) and to identify the characteristic features of a humanistic model in IKEA.Design/methodology/approachThis study included a review of the scientific literature and a narrative case study via semi-structured interviews with top management leaders and middle managers.FindingsThe research demonstrates that the effectiveness of EB depends on the implementation of a humanistic model and that IKEA uses a business paradigm that involves EB through a humanistic management model. In addition, the pandemic has enhanced prosocial management and revealed the need for this model in companies. Through the analysis of the humanistic model used by IKEA, the authors provide an example of how other organizations and business leaders can develop communities and society not based on profit maximization. However, further research is needed to contrast the quantitative information provided by the company itself and by external sources. What is offered in this article is the starting point for future studies on this topic.Originality/valueThis is one of the first studies on EB in the context of a humanistic model and the first to use IKEA as a paradigmatic example.

Authors: Yang Weichao , Liu Yikang , Deng E. , Wang Youwu , He Xuhui , Lei Mingfeng , Zou Yunfeng 
Published: August 2022

Purpose
The purpose of this paper is to understand the natural wind field characteristics of the tunnel entrance section and analyzing the aerodynamic performance of high-speed railway trains (HSRTs) under natural winds.

Design/methodology/approach
Three typical tunnel entrance section sites, namely, tunnel–bridge in a dry canyon (TBDC), tunnel–bridge in a river canyon (TBRC) and tunnel–flat ground (TF), are selected to conduct a continuous wind field measurement. Based on the measured wind characteristics, the natural winds of the TBDC and TF sites are reconstituted and imported into the two corresponding full-scale computational fluid dynamics models. The aerodynamic loads of the HSRT running on TBDC and TF with reconstituted winds are simply analyzed.

Findings
The von Kármán spectrum can be used to describe the wind field at the tunnel entrance section. In the reconstituted natural wind condition, a time-varying feature of wind speed distribution and leeward side vortex around the HSRT caused by the wind speed fluctuation is found. The fluctuating amplitude of aerodynamic loads at the TBDC infrastructure is up to 97.9% larger than that at the TF infrastructure.

Originality/value
The natural wind characteristics at tunnel entrance sections on the high-speed railway are first measured and analyzed. A numerical reconstitution scheme considering the temporal and spatial variation of natural wind speed is proposed and verified based on field measurement results. The aerodynamic performance of an HSRT under reconstituted natural winds is first investigated.

Published: August 2022

PurposeGlobal construction has been affected by COVID-19 unprecedently. The construction sectors in the least developed countries are considered as vulnerable, but the covid made the countries experience the worst situation ever. To minimize the losses by effective measures, there needs to assess the COVID-19 impacts on the construction sector. So, the aim of this study is to investigate the most critical impacts of COVID-19 on construction in the least developed countries by considering the case study of Bangladesh.Design/methodology/approachThe authors adopted multistep research methods, including (1) literature analysis and discussion with experts to establish a comprehensive list of COVID-19 impacts; (2) through a questionnaire survey, data were collected from 217 construction professionals by email, Google Form and Skype for quantifying the significance of covid impacts; (3) reliability of the survey checked by the Cronbach Alpha test; (4) Relative Importance Index (RII) to determine the ranks of the impacts based on their significance; (5) Interpretive Structural Model (ISM) to explore the corelations and the hierarchical structure; and (6) cross-impact matrix multiplication applied to classification (MICMAC) analysis to classify the COVID-19 impacts.FindingsThe study identified a total of 18 COVID-19 impacts on the construction sector. Among them, the job cuts, schedule delays, project suspension, cost overrun and effects on mental health are more influential and significant than others. Further, this study found that unpaid leave and job cuts are the two most fundamental impacts which influence other succeeding significant impacts. And ultimately all the impacts lead to hampering the national economy and development. Finally, MICMAC analysis suggested that unpaid leave and job cuts should be addressed first to resolve and effects on the national economy and development should be later.Research limitations/implicationsThis study does not consider all the COVID-19 impacts due to the relevant context and simplicity of the ISM method. Also, the respondent's attitude might be slightly different during the post-mass vaccination period.Practical implicationsThis study will help the company's management, employees and government to develop effective strategies to understand the insight of their interrelations and ultimately overcome the identified covid effects. This will must contribute to the industry, its employees, the government and society by ensuring the national economy and development, construction operations, investment, employment and social security.Originality/valueThis study will contribute to the knowledge body (practitioners and researchers) by providing the list of significant covid impacts and insight into their interrelations for further deep analysis of the pandemic effects. This will also help the authorities and stakeholders in developing policies and strategies to minimize or avoid these effects and avoid future consequences due to any pandemic like covid.
Critical success factors of Lean in Higher Education: an international perspective
Authors: Kokkinou Alinda , van Kollenburg Ton 
Published: August 2022

Purpose
Continuous improvement initiatives such as Lean in Higher Education (HE) institutes are an emerging topic for research. Under pressure to do more with less, institutes of HE are increasingly adopting the tools and methods of lean to improve their quality practices. Nevertheless, institutes of HE differ significantly from business organizations. The purpose of this study was to examine the critical success factors (CSFs) of continuous improvement in this homogeneous industry. Two other contextual factors, implementation approach and national culture, are examined.

Design/methodology/approach
A mixed methods approach, combining Q-methodology, online surveys and interviews, was used to investigate the CSFs of lean implementation in HE. Participants were recruited from an international network of lean practitioners in HE. Using Q-methodology, three perspectives of CSFs in HE were identified.

Findings
Lean implementation at institutes of HE is characterized by a bottom-up approach, involving mostly supporting processes. Contrary to business organizations, the role of management in the implementation of Lean in HE is limited and attention should instead be directed to employee empowerment and customer focus. The findings also showed that, at least for institutes of HE, organizational culture is more influential than national culture.

Practical implications
When management involvement is limited, a bottom-up implementation of lean is recommended, centered on improving university-wide supporting processes, promoting cross-departmental cooperation and overcoming the silo mentality. This approach requires an emphasis on a specific set of CSFs, namely, employee empowerment, sharing success stories and training.

Originality/value
The study findings enrich conceptually based lean implementation frameworks for HE that advocate a top-down implementation approach.
An investigation of battery storage operating strategies in the context of smart cities
Authors: Yao Xing , Ma Shao-Chao , Fan Ying , Zhu Lei , Su Bin 
Published: August 2022

PurposeThe ongoing urbanization and decarbonization require deployment of energy storage in the urban energy system to integrate large-scale variable renewable energy (VRE) into the power grids. The cost reductions of batteries enable private entities to invest energy storage for energy management whose operating strategy may differ from traditional storage facilities. This study aims to investigate the impacts of energy storage on the power system with different operation strategies. Two strategies are modeled through a simulation-based regional economic power dispatch model. The profit-oriented strategy denotes the storage system operated by private entities for price arbitrage, and the nonprofit-oriented strategy denotes the storage system dispatched by an independent system operator (ISO) for the whole power system optimization. A case study of Jiangsu, China is conducted. The results show that the profit-oriented strategy only has a very limited impact on the cost reductions of power system and may even increase the cost for consumers. While nonprofit-oriented energy storage performs a positive effect on the system cost reduction. CO2 emission reduction can only be achieved under a high VRE scenario for energy storage. Integrating energy storage into the power system may increase CO2 emissions in the near term. In addition, the peak-valley spread is crucial to trigger operations of profit-oriented energy storage, and the profitability of energy storage operator is observed to be decreasing with the total storage capacity. This study provides new insights for the energy management in the smart city, and the modeling framework can be applied to regions with different resource endowments.Design/methodology/approachThe authors characterize two battery storage operating strategies of profit- and nonprofit-oriented by adopting a simulation-based economic dispatch model.

A grounded theory of information exclusion and information inclusion: framing the information experience of people seeking asylum
Authors: Le Louvier Kahina , Innocenti Perla 
Published: August 2022

PurposeThis paper discusses an original theory of information exclusion and information inclusion, which explains how information interactions can be structured in ways that either exclude or include people seeking asylum.Design/methodology/approachThis theory was developed through an ethnographic study of the information experience of people seeking asylum in the United Kingdom. Fieldwork involved participant observations, participatory research workshops and semi-structured interviews, analysed using a constructivist grounded theory approach.FindingsPeople seeking asylum are confronted with two main information environments: the asylum system and the local third sector. Each environment frames contrasting information access, sharing and literacy practice modalities: the former produces information deprivation, information sharing agency denial and a fracturing information literacy practice; the latter facilitates multiple information affordances, information sharing agency promotion, and both local and heritage information literacy practice promotion. Our theory of information exclusion and information inclusion describes how through these modalities, an information environment can either promote or preclude inclusion.Originality/valuePrevious information studies of migration tend to conceptualise social ex/inclusion as a linear journey. Our theory originally frames this as a non-straightforward and conflicting process, allowing to better understand the experience of people who are not simply either socially excluded or included, but may experience both states depending on context. It also shows that exclusion is not a matter of fact and is not fundamental to asylum systems: it is produced by specific policies and procedures and can therefore be changed. Thus, this theory provides conceptual tools for researchers to investigate the information experience of individuals moving between conflicting information practices, and for civil society actors and policymakers to document exclusionary information practices and design inclusive ones.

Published: August 2022

PurposeThe purpose of this study was to establish a line of inquiry into student trust in school peers by: (1) developing a valid and reliable measure and (2) investigating the potential influence of student trust in school peers on optimal school functioning.Design/methodology/approachA non-experimental, survey research design was used. Ex-post facto data were collected in the spring of 2017 and spring of 2019 from a random sample of students in either the 5th, 7th, 9th or 11th grades in 79 schools located in a southwestern city in the US. Two types of analyses were performed. First, structural and convergent validity of the items measuring student trust in school peers were tested with a confirmatory factor analysis, and correlations with bullying and safety. The second analysis tested a hypothesized model with a full structural equation model using robust maximum likelihood estimation.FindingsConfirmatory factor analysis results report that items used to measure student trust in school peers share common variance with the latent trust factor. Both the 10-item and five-item measures had good model fit and parameter estimates. Additionally, the five-item measure had strong relationships with bullying and safety. As specified in the hypothesized model, student trust in peers had a strong, positive relationship with identification with school and positive, yet not as strong, of a relationship with academic grit. These relationships existed when accounting for student perceived teacher support.Originality/valueThis study extends trust research to students' relational connections by conceptualizing student trust in school peers as a cognitive belief, constructing a valid measure and finding a relationship between student–peer trust and elements optimal school functioning.
Should we stop using the label of “paternalistic leadership”? Evidence from three Chinese samples
Authors: Wong Chi-Sum , Lan Junbang , Peng Kelly Z. , Iun Joyce 
Published: August 2022

PurposeProponents of paternalistic leadership argue that a paternalistic leader is authoritative and at the same time, a benevolent and moral individual, and this style is effective in non-Western societies. However, past empirical studies consistently found that authoritarianism related negatively to benevolence, morality and job outcomes. The authors posit that the original proposed style probably did not exist, or at least not being a dominant style, in modern Chinese business organizations.Design/methodology/approachThe authors collected supervisor–subordinate dyadic data from three independent Chinese sample in Taiwan (N = 305), Hubei (N = 350) and Jiangsu (N = 270) and utilized the latent profile analysis method to test the hypotheses.FindingsFirst, authoritarianism ratings are much lower than ratings of benevolence and morality. Second, none of the identified profiles is high on authoritarianism, benevolence and morality at the same time. Third, leadership style with low authoritarianism, but high on benevolence and morality leads to the best employee outcomes.Originality/valueConceptually, the authors clarify the typical leadership styles that compose of the independent dimensions proposed by paternalistic leadership researchers. Methodologically, the authors showed that using person-centered latent profile analysis method can examine combinations of various leadership dimensions or constructs to examine a leader as a whole person. Practically, understanding a leadership style that composes of different levels of various leadership constructs may better inform managers and leaders how they could effectively influence subordinates.
