SummaryIBD is characterized by altered immune reactions and infections are thought to trigger the chronic inflammatory response in IBD. The gut represents a productive reservoir for SARS-CoV-2 and the aforementioned factors together with immunosuppression used to treat IBD are likely influencing the outcomes of IBD patients in COVID-19. We used large and small intestinal organoids from IBD patients and controls to comparatively assess the transcriptional response of the gut epithelium during SARS- CoV-2 infection. Our analysis showed that IBD epithelia exhibit reduced viral loads compared to controls associated with a reduced expression of SARS-CoV-2 entry factors including the host receptor ACE2. Moreover, several genes implicated in the epithelial response to viral infection are intrinsically altered in IBD likely counteracting viral propagation. Notably, differences between IBD phenotypes exist wherein ulcerative colitis represents with induced cell death pathways and an induction of IL-1β despite overall lower viral loads suggestive of increased epithelial stress in this IBD phenotype. Altogether our analysis shows that IBD epithelia are not more prone to SARS-CoV-2 infection but epithelia from ulcerative colitis and Crohn’s disease exhibit specific differences which might explain the differing COVID-19 outcomes between IBD phenotypes.
Putting the customer at the center: does store managers' ethical leadership make a difference in authentic customer orientation?
Authors: Ruiz-Palomino Pablo , Linuesa-Langreo Jorge , Rincón-Ornelas Rosa María , Martinez-Ruiz M. Pilar 
Published: June 2023

PurposeThe purpose of this article is to explore the mediating role of both ethical climate and frontline employees' ethical intent on the relationship between store managers' ethical leadership and frontline employees’ customer orientation (FECO).Design/methodology/approachOriginal data on small and medium-sized enterprises in the Mexican retail industry were used. A survey provided a sample of 332 frontline employees. To test the hypotheses, the authors conducted a partial least squares (PLS) analysis.FindingsThe results show the positive effect of ethical leadership is mainly direct. This can primarily be explained through the mechanisms of social exchange theory. Additionally, the results show that ethical climate and ethical intent act as essential partial mediators.Originality/valueAlthough managers' ethical leadership typically exercises a direct and positive influence on employees' work performance, the path linking the ethical leadership of the upper echelons to this outcome has not been frequently studied, especially in terms of its impact on meeting customers' needs (i.e. frontline employees' customer orientation, or FECO). This study expands on existing knowledge by considering that a true FECO is necessarily linked to being “oriented to others”, which is fostered by the perception that moral values (i.e. honesty) are embedded in an organization's culture.

Authors: Mierzejewska Wioletta , Górska Rumiana , Aluchna Maria , Krejner-Nowecka Anna , Dziurski Patryk 
Published: June 2023

PurposeCoopetition is ubiquitous in the economy, but managing effectively this type of relationship between firms remains a challenge for many organizations. This paper investigates the coopetition within corporate groups and focus on factors that determine the simultaneous competition and cooperation between subsidiaries therein.Design/methodology/approachDrawing on a dataset of 121 corporate groups listed on the Warsaw Stock Exchange (WSE), this paper theoretically advances and empirically validates the impact of 18 factors which determine the coopetition relationship.FindingsThis study's findings confirm the importance of an organizational design among external and internal drivers of intrafirm coopetition. However, the role of an environmental uncertainty as a driver of intrafirm coopetition is not proven. Furthermore, the paper finds that internal determinants explain the phenomenon of coopetition between subsidiaries within a corporate group more than determinants related to the environment.Originality/valueThe paper contributes to the coopetition theory by empirical identification of drivers of intrafirm coopetition and advances the corporate groups studies by exploring internal relationships (cooperation and competition) and the determinants therein.

Authors: S.N. Archana , P.K. Padmakumar 
Published: June 2023

Purpose
The purpose of this study was to understand the landscape of Indian research data repositories (RDRs) indexed in the re3data.org. The study analysed the metadata elements of Indian RDRs to identify their disciplinary orientations, typology, standards adopted, foreign collaborations, etc. The study ascertained the current status of the Indian RDRs by visiting their respective websites and tried to identify and map the exact disciplinary orientation of each RDR.

Design/methodology/approach
The study used “content analysis” of the metadata elements extracted from re3data.org along with the information analysis of the respective websites of the registered RDRs.

Findings
The study identified that only 80% of the Indian RDRs listed by the re3data.org is currently active. Most of the Indian RDRs are hosted by the central and state governments and are almost equally distributed among Life Sciences, Natural Sciences and Social Sciences domains. The data provided by the re3data.org for the Indian RDRs are not complete and up-to-date.

Practical implications
The findings indicate the presence of a good number of inactive RDRs in the re3data.org. The study suggests using a revised version of the DFG subject classification scheme or considering a standard classification scheme for subject indexing.

Originality/value
To the best of the authors’ knowledge, this study is the first of its kind that critically analysed the metadata values extracted and moved further to identify the current status of Indian RDRs.

Authors: Li Zhanfu , Liang Jianbin , Jia Peiyu , Zheng Shaoqi , Zhou Hongzhi , Tong Xin 
Published: June 2023

PurposeThe purpose of this paper is to study the screen surface parameters of the double deck vibrating screen, in sections, to determine the influence of each part of the screen surface on the screening efficiency of the vibrating screen. Finally, the best screening parameters were calculated to obtain the best screening performance.Design/methodology/approachIn this paper, the discrete element method is used to simulate the process of two-layer subsection screening. Response surface test was used to analyze the influence of various factors and their interactions on screening results. Finally, based on the binomial regression model of screening efficiency, the optimal combination of vibration parameters is calculated.FindingsIn the screening process of vibrating screen, due to the different screening environments in each area of the screen surface, the single-layer linear vibrating screen with equal screen surface parameters cannot obtain the best screening performance. Among the single factors, the effect of vibration frequency is the most significant.Originality/valueTo address the issue of single layer linear vibrating screens with equal screen surface parameters being unable to maintain optimal screening performance when handling large amounts of materials. This article proposes a double layer vibrating screen with different screen surface grids and screen surface angles to address the problem of low screening performance of traditional single layer linear vibrating screens.
Returnee firms, R&D input and innovation performance: critical roles of political and economic stakeholders
Authors: Dong Caiting , Liu Xielin , Zhang Si 
Published: June 2023

PurposeAlthough the role of returnees is critical to firm innovation, the literature offers inconsistent findings regarding returnees' effect on firms' innovation performance. To reconcile this issue, the authors argue that taking the types of innovation into account – i.e. technical innovation and commercial innovation – is necessary. Thus, the purpose of this study is to examine how firms led by returnees affect the relationship between research and development (R&D) input and above two types of innovation output, as well as the contingent role of political connections (PCs) and venture capital funding (VC funding).Design/methodology/approachThis study empirically tested the hypotheses using a dataset of 54,617 firm-year observations for 18,475 Chinese firms in Zhongguancun Science Park (ZSP) from 2009 to 2014.FindingsThe results show that the positive effect of R&D input on technical innovation performance (TIP) is reinforced when firms are led by returnees, while the positive effect of R&D input on commercial innovation performance (CIP) is weakened when firms are led by returnees compared with those firms led by the local counterparts. The findings further show that returnee firms' positive effect on the relationship between R&D input and technical innovation performance is more salient for firms with more PCs but weakened for those with more VC funding.Originality/valueThis study enriches the research on returnee firms' advantages and disadvantages in transforming R&D input into innovation performance, and the findings highlight that firms led by returnees can increase R&D efficiency of technical innovation, but reduce R&D efficiency of commercial innovation. Moreover, this study offers a contingent view of political and economic stakeholders' roles in returnee firms' innovation, by revealing PCs help returnee firms to enhance R&D efficiency in technological innovation, while venture capital can hamper such R&D efficiency.
The interplay between firms’ capabilities and ownership in explaining environmental performance
Authors: Forés Beatriz , Camisón-Zornoza César , Fernández-Yáñez José María 
Published: June 2023

PurposeThis study empirically assesses the effects of two key types of organizational and managerial capabilities—dynamic capabilities, and coordination and cohesion capabilities—on environmental performance, considering the moderating effect of family ownership. By applying the tenets of the natural resource-based view and the dynamic capabilities theory, this paper offers new insights into the topic.Design/methodology/approachThe article presents empirical evidence from a survey of 1,019 firms operating in the Spanish tourism sector analyzed using multiple linear regression.FindingsOverall, our results show that both dynamic capabilities and coordination and cohesion capabilities have direct and synergetic positive effects on environmental performance. In addition, the results confirm recent studies that report conflicting evidence on how family ownership affects environmental performance: family ownership is found to exert a distinct direct effect on environmental performance and on the development and application of the capabilities required to improve such performance.Originality/valueThis article sheds light on the conceptual frontiers between the different types of capabilities, as well as provides practical ways of measuring them. The article also brings evidence to bear on the debate concerning the direct and moderating effect that family ownership exerts on the relationship between both types of capabilities over environmental performance. The results of this analysis confirm the complexity of the family ownership effect on this aspect, and provide important insights for both business practitioners and academics.
A historical review of sustainable construction in Nigeria: a decade of development and progression
Authors: Isang Inimbom Walter 
Published: June 2023

PurposeResearch studies related to sustainability and green building have made monumental contributions to the concept of sustainable construction (SC) in Nigeria. This paper therefore aims to present a historical review of the development of SC in Nigeria over a 10 year period. The review also provides constructive perspective on the benefits of SC and the present state of enforcement of green building in Nigeria.Design/methodology/approachA historical review strategy was applied to the study. Using secondary data sources, 47 influential journals from emerald, scopus and science direct database focusing on “SC”, “sustainability” and “green building” in Nigeria between 2012 and 2022 were used for the analysis.FindingsThe analysis deduced that the development of SC in Nigeria have undergone a triple period of development: the inception period (2012–2016), the transition period (2016–2020) and the advancement period (2020–present). The review juxtaposes the three timeline to show rapid growth in the awareness of SC, but revealed moderate levels of implementation in some major cities in Nigeria. Therefore, the author finds and argues that the advancement of SC in Nigeria can be achieved through the synergy, commitment and active roles of researchers, academics, practitioners, policy makers and the government in enforcing existing green policies.Originality/valueThe study is the first academic paper to undertake a decade long historical review of SC in Nigeria. This review provides an up-to-date understanding of the developments, changing dynamics and future progressions in the field of SC in Nigeria.
Strategic factors conferring organizational resilience in SMEs during economic crises: a measurement scale
Authors: Verreynne Martie-Louise , Ford Jerad , Steen John 
Published: June 2023

PurposeThe paper aims to develop a strategic conceptualization and measurement scale of organizational resilience to support researchers examining how small firms prepare and respond deliberately to general disruptions in the operating environment over more extended time frames.Design/methodology/approachThe paper uses a four-step process to develop, present and test (for predictive validity) a scale of strategic organizational resilience for frequent events or those needing long-term responses.FindingsThe resulting seven-factor measurement scale of organizational resilience consists of readiness, slack, problem-solving, flexibility, connectedness, adaptiveness and proactiveness.Originality/valueThe literature on organizational resilience explains how organizations recover from rare but catastrophic events by focusing on adaptation principles and short-term survival. The broader conceptualization presented here enables the study of organizational resilience in small-medium size enterprises (SMEs) across more frequent and pervasive events, such as financial crises, industry downturns and other forms of structural change and technological disruption. This is operationalized in a measure that includes new strategic factors associated with forward-planning and more traditional operationally focused elements.
How family firms can avoid the trap of strong social ties and still achieve innovation: critical roles of market orientation and transgenerational intent
Authors: Dayan Mumin , Ng Poh Yen , De Clercq Dirk 
Published: June 2023

PurposeTo extend family business research, this article proposes and tests a curvilinear relationship between social ties and family firm innovation, with the firm's market orientation and transgenerational intent as moderators.Design/methodology/approachRepresentatives from a sample of 150 family firms in the United Arab Emirates completed self-administered questionnaires. Regression analyses on the collected data test the conceptual model and proposed hypotheses.FindingsThe empirical study reveals an inverted U-shaped relationship, such that a high market orientation mitigates the diminishing returns of social ties on enhancing family firm innovation. Similarly, at high levels of transgenerational intent, family firm innovation increases due to social ties, instead of exhibiting diminishing returns.Originality/valueThese results help explain contradictory outcomes previously attributed to social ties and offer clear guidelines for how family firms can leverage these ties more effectively to enhance their own innovation.

Authors: Ali-Knight Jane , Kerr Gary , Stewart Hannah , Holmes Kirsten 
Published: June 2023

PurposeIn this paper, the authors explore how Edinburgh's key Festivals have adapted to the COVID-19 pandemic. Their response presents the emergence of more innovative festival delivery models and a different imagining of the festival space.Design/methodology/approachThe authors use a qualitative mixed methods research design involving 13 in-depth semi-structured interviews with Edinburgh's Festival Directors and other cultural and policy stakeholders as part of a University-funded stand-alone research project. The interviews were supplemented with participant observation at festivals virtually and in-person to experience new and emerging formats of festival content delivery, adherence to Scottish Government guidelines on COVID-19 safety, and to experience attending festivals during a pandemic.FindingsThe authors present findings on how Edinburgh's Festivals have responded to Covid-19 and how they have adapted – and in some cases reimagined – their business models to survive.Originality/valueThe authors propose a new theoretical framework that establishes a model for how festivals can approach risk management within their business model, focused on the ‘3R's’ – respond, resilience and reimagine –with communication and support being central to this framework.
Organizational mission and digital platform evolution: an investigation of entrepreneurial organizations in nascent markets
Authors: Roberts Nicholas , Kim Inchan 
Published: June 2023

PurposeAlthough digital platforms have become important to organizations and society, little is known about how platforms evolve over time. This is particularly true for early-stage platforms provided by entrepreneurial firms competing in nascent markets. This study aims to investigate the relationship between a platform provider's mission and the evolution of its digital platform.Design/methodology/approach This study conducted an exploratory, multi-case study of startups in the emerging health/fitness wearables market over the period 2007 to 2016.FindingsThis study emerged two organizational mission constructs – consistency and specificity – and two evolutionary dynamics of digital platforms – unity and evolution rate. It also considered unity and evolution rate in terms of features created by the platform provider and features connected by external parties. This study found relationships between aspects of mission consistency and platform unity and identified relationships between aspects of mission specificity and platform evolution rates.Originality/valueThis study formalized findings into a set of theoretical propositions, thereby enriching the understanding of the relationship between organizational mission and digital platform evolution in nascent markets. This study provides new constructs and relationships that can be tested and refined in future research.
A nonlinear robot joint friction compensation method including stick and sliding characteristics
Authors: Feng Yanli , Zhang Ke , Li Haoyu , Wang Jingyu 
Published: June 2023

Purpose
Due to dynamic model is the basis of realizing various robot control functions, and it determines the robot control performance to a large extent, this paper aims to improve the accuracy of dynamic model for n-Degree of Freedom (DOF) serial robot.

Design/methodology/approach
This paper exploits a combination of the link dynamical system and the friction model to create robot dynamic behaviors. A practical approach to identify the nonlinear joint friction parameters including the slip properties in sliding phase and the stick characteristics in presliding phase is presented. Afterward, an adaptive variable-step moving average method is proposed to effectively reduce the noise impact on the collected data. Furthermore, a radial basis function neural network-based friction estimator for varying loads is trained to compensate the nonlinear effects of load on friction during robot joint moving.

Findings
Experiment validations are carried out on all the joints of a 6-DOF industrial robot. The experimental results of joint torque estimation demonstrate that the proposed strategy significantly improves the accuracy of the robot dynamic model, and the prediction effect of the proposed method is better than that of existing methods.

Originality/value
The proposed method extends the robot dynamic model with friction compensation, which includes the nonlinear effects of joint stick motion, joint sliding motion and load attached to the end-effector.
Financial constraints and nonlinearity of farm size growth
Authors: Bojnec Štefan , Fertő Imre 
Published: June 2023

PurposeThis article aims to investigate the financial constraints and nonlinearity of farm size growth.Design/methodology/approachFarm size growth is measured with land, labor and output using data from the Farm Accountancy Data Network (FADN) for Hungary and Slovenia. A dynamic panel model is applied to assess financial constraints and nonlinearity of farm size growth.FindingsResults show that, except for land in Slovenia and output in Hungary, liquidity constraints are less important for farm size growth than endogenous factors based on farm size growth expectations and steady farm size restructuring. Smaller farms are growing faster than larger ones. The hypothesis that a higher level of subsidies would increase farm size is not supported for Hungary. When farms reach a certain size, the land area of the largest farms increases. Farm debts in Hungary are linked with land growth and in Slovenia with output growth.Research limitations/implicationsFurther research on the impact of liquidity constraints and subsidies can be conducted at a disaggregate farm-type level to examine whether there is variability in the underlying interlinkages at the farm-type specialization level.Practical implicationsThe implication that farm size growth is dependent on initial size and that smaller farms are growing faster than bigger ones indicates that it is not necessary to favor the fastest growing smaller farms thus supports the application of a non-discriminatory farm size policy for observing farm size structural changes.Originality/valueThe dynamic panel econometric model that incorporates cash flow as a measure of financial constraints provides insight into farm size growth in cross-country comparison in relation to potential farm liquidity constraints, farm debt and the nonlinearity of farm size, which information is of relevance to policy makers and practitioners.
