Published: April 2021

AbstractSymbiosis between cyanobacteria and plants is considered pivotal for biological nitrogen deposition in terrestrial ecosystems. Despite the large knowledge in the ecology of plant-cyanobacteria symbioses, little is known about the molecular mechanisms involved in the crosstalk between partners. A SWATH-mass spectrometry has been used to analyse, at the same time, the differential proteome ofOryza sativaandNostoc punctiformeduring the first events of the symbiosis.N. punctiformeactivates the expression of thousands of proteins involved in signal transduction and cell wall remodelling, as well as 11 Nod-like proteins that might be involved in the synthesis of cyanobacterial-specific Nod factors. InO. sativathe differential protein expression was connected to a plethora of biological functions including signal transduction, defense-related proteins, biosynthesis of flavonoids and cell wall modification.N. punctiformesymbiotic inspection ofO. sativamutants in the SYM pathway reveals the involvement of this ancestral symbiotic pathway in the symbiosis between the cyanobacterium and the plant.

AbstractMany genome assemblies have been found to be incomplete and contain misassemblies. The Vertebrate Genomes Project (VGP) has been producing assemblies with an emphasis on being as complete and error-free as possible, utilizing long reads, long-range scaffolding data, new assembly algorithms, and manual curation. Here we evaluate these new vertebrate genome assemblies relative to the previous references for the same species, including a mammal (platypus), two birds (zebra finch, Anna’s hummingbird), and a fish (climbing perch). We found that 3 to 11% of genomic sequence was entirely missing in the previous reference assemblies, which included nearly entire GC-rich and repeat-rich microchromosomes with high gene density. Genome-wide, between 25 to 60% of the genes were either completely or partially missing in the previous assemblies, and this was in part due to a bias in GC-rich 5’-proximal promoters and 5’ exon regions. Our findings reveal novel regulatory landscapes and protein coding sequences that have been greatly underestimated in previous assemblies and are now present in the VGP assemblies.
Practical measurement of the energy resolution for meV-resolved inelastic X-ray scattering
Authors: Ishikawa Daisuke , Baron Alfred Q. R. 
Published: April 2021

Several different ways of measuring the energy resolution for meV-resolved inelastic X-ray scattering (IXS) are compared: using scattering from poly(methyl methacrylate), PMMA, using scattering from borosilicate glass (Tempax), and using powder diffraction from aluminium. All of these methods provide a reasonable first approximation to the energy resolution, but, also, in all cases, inelastic contributions appear over some range of energy transfers. Over a range of ±15 meV energy transfer there is good agreement between the measurements of PMMA and Tempax at low temperature, and room-temperature powder diffraction from aluminium, so we consider this to be a good indication of the true resolution of our ∼1.3 meV spectrometer. The resolution over a wider energy range is self-consistently determined using the temperature, momentum and sample dependence of the measured response. The inelastic contributions from the PMMA and Tempax, and their dependence on momentum transfer and temperature, are then quantitatively investigated. The resulting data allow us to determine the resolution of our multi-analyzer array efficiently using a single scan. The importance of this procedure is demonstrated by showing that the results of the analysis of a spectrum from a glass are changed by using the properly deconvolved resolution function. The impact of radiation damage on the scattering from PMMA and Tempax is also discussed.
Remodelling public sector knowledge management system using key knowledge management processes
Authors: Dikotla Maoka Andries 
Published: April 2021

Purpose
The purpose of this paper is to recommend a framework for remodelling a public sector knowledge management system (KMS) using key knowledge management (KM) processes. The rationale is to provide insight and guidelines to organisations that struggle with KM.

Design/methodology/approach
This desktop study adopted the qualitative approach and literature to support the understanding regarding the remodelling of the public sector KMS using key KM processes.

Findings
The study found that if KM processes are not considered, the prospect of KM is limited. The best way to manage public sector knowledge is following KM processes using information technology. Without proper KM, organisations may not know how knowledge is generated, codified, stored, shared and used in an organisation.

Originality/value
The paper provides a framework to guide public sector organisations in the implementation of electronic KM. Thus, proposing a new way of managing knowledge by using the electronic KM processes in the public sector organisations. The study will also benefit other organisations implementing KM programmes.
Numerical algorithm for two-dimensional nonlinear Volterra-Fredholm integral equations and fractional integro-differential equations (of Hammerstein and mixed types)
Authors: Wang Jiao 
Published: April 2021

Purpose
This paper aims to propose an efficient and convenient numerical algorithm for two-dimensional nonlinear Volterra-Fredholm integral equations and fractional integro-differential equations (of Hammerstein and mixed types).

Design/methodology/approach
The main idea of the presented algorithm is to combine Bernoulli polynomials approximation with Caputo fractional derivative and numerical integral transformation to reduce the studied two-dimensional nonlinear Volterra-Fredholm integral equations and fractional integro-differential equations to easily solved algebraic equations.

Findings
Without considering the integral operational matrix, this algorithm will adopt straightforward discrete data integral transformation, which can do good work to less computation and high precision. Besides, combining the convenient fractional differential operator of Bernoulli basis polynomials with the least-squares method, numerical solutions of the studied equations can be obtained quickly. Illustrative examples are given to show that the proposed technique has better precision than other numerical methods.

Originality/value
The proposed algorithm is efficient for the considered two-dimensional nonlinear Volterra-Fredholm integral equations and fractional integro-differential equations. As its convenience, the computation of numerical solutions is time-saving and more accurate.
After the disclosure: measuring the short-term and long-term impacts of data breach disclosures on the financial performance of organizations
Authors: Avery Atiya 
Published: April 2021

PurposeThis study aims to evaluate changes to the financial performance of organizations in the 1–4 quarters following a data breach event. The study introduces two new variables, “intangible assets” and “extraordinary losses” to the discussion on the impact of data breaches on an organization’s financial performance. Intangible assets allow us to gauge the data breach’s impact on the organization’s brand reputation and intellectual capital reserves. Extraordinary losses allow us to gauge if organizations considered data breaches truly detrimental to their operations that they rose to the level of “extraordinary” and not an event that could be incorporated into its usual operating expenses.Design/methodology/approachThis study uses a matched sample comparison analysis of 47 organizations to understand the short-term and long-term impacts of data breach events on an organization’s financial performance.FindingsData breach events have some negative impacts on the organization’s profitability more than likely leading to a depletion of the organization’s assets. However, organizations do not perform better or worse in the short-term or long-term due to a data breach event; the organizations can be considered financially sustainable in the 1–4 quarters following a data breach disclosure.Originality/valueThis study takes two approaches to theory development. The first approach extends the current literature on data breach events as negative, value declining events to the organization’s performance, which is referred to as the “traditional view.” The second view posits that a data breach event may be a catalyst for enhanced long-term organization performance; this is referred to as the organizational sustainability and resiliency view.

Literature review was performed to comprehend various aspects pertaining to building adaptive reuse. Three questionnaire surveys were administered on 90 AEC/FM practitioners, to investigate the current practices of adaptive reuse projects in Saudi Arabia. The questionnaire surveys were directed to 30 architects/engineers (A/Es), 30 contractors and 30 facilities managers, respectively, through face-to-face interviews. The qualitative and quantitative findings of each questionnaire survey were analyzed. Recommendations were proposed for each of the professional domains, to enhance the overall AEC/FM performance in future adaptive reuse projects.FindingsThe findings pointed out the necessity of accurately planning and designing the adaptive reuse in accordance with the spatial, technical, legislative, economic and functional considerations. The findings revealed the significance of contractors' role in conducting effective supervision over the managerial and technical processes during the implementation of the change of use. It also indicated the importance of the facilities managers' role in performing all daily operational activities, to maintain satisfactory performance of the adaptively reused buildings.Originality/valueThis paper contributes to the relevant literature to the building adaptation, through investigating the perspectives of AEC/FM practitioners on adaptive reuse projects. The findings would enable AEC/FM practitioners to improve their professional practices in future adaptive reuse projects, in an integrated manner.
Using positive deviance to enhance employee engagement: an interpretive structural modelling approach
Authors: Sharma Naman 
Published: April 2021

PurposeOrganisations today seek high engagement levels from their employees for their superior performance amid the highly competitive environment. The purpose of this paper is to examine the role of positive deviance facilitators (PDFs) in enhancing employee engagement at work.Design/methodology/approachThe study adopts the interpretive structural modelling (ISM) and Matrice d’Impacts Croisés-Multiplication Appliquée á un Classement (MICMAC) analysis to understand the process of how positive deviance may fuel employee engagement in an organisation. Because of the lack of empirical evidence on the relationship between employee engagement and positive deviance, ISM approach was adopted as it helps in understanding the subjective experience and learnings of experts involved in the field. The MICMAC analysis classifies the relevant factors into four clusters and helps in understanding the dynamics involved.FindingsBased on the opinions shared by industry and academia experts, a structural model was developed to understand the hierarchy and interactions among the eight PDFs leading towards employee engagement.Research limitations/implicationsThe study offers both theoretical and practical implications. The model developed in the current study could be used as a base model for future studies concerning employee engagement and deviance. The importance of human resource management practices in fuelling positive deviance and employee engagement is also highlighted. The study discusses various practical implications for human resource managers and top management.Originality/valueThe literature on positive deviance at work is still at a nascent stage. Empirical studies on deviance largely focus on the destructive/negative side of workplace deviance, and studies on positive outcomes from workplace deviance are rare. This present study provides a unique opportunity to understand how positive deviance can be used to enhance the engagement levels of employees.

The main aim of this paper is to obtain a detailed picture of the field via bibliometric analysis to identify research streams and future research agenda.Design/methodology/approachThe data sample consists of 472 papers in several bibliometric exercises. Citation and collaboration structure analyses are employed to identify most important authors and journals and track the interconnections between main authors and institutions. Next, content analysis based on bibliographic coupling is conducted to identify main research streams in TFP.FindingsThree research streams in agricultural TFP research were distinguished: TFP growth in developing countries in the context of policy reforms (1), TFP in the context of new challenges in agriculture (2) and finally, non-parametric TFP decomposition based on secondary data (3).Originality/valueThis research indicates agenda of future TFP research, in particular broadening the concept of TFP to the problems of policy, environment and technology in emerging countries. It provides description of the current state of the art in the agricultural TFP literature and can serve as a “guide” to the field.
Supportive study climate and academic performance among university students: the role of psychological capital, positive emotions and study engagement
Authors: Slåtten Terje , Lien Gudbrand , Evenstad Solveig Beyza Narli , Onshus Terje 
Published: April 2021

Purpose
The overall aim of this study is to explore factors associated with academic performance among university students. Specifically, it explores whether a supportive study climate is directly related to academic performance and whether students’ psychological capital (PsyCap), positive emotions and study engagement play a role in the relationship between supportive study climate and academic performance.

Design/methodology/approach
A total of 588 bachelor students from a range of academic programs participated in a survey. The partial least squares (PLS)-based structural equation modeling (SEM) was used to test the conceptual models and the hypothesized relationships, using the software SmartPLS.

Findings
No support was found for a direct relationship between supportive study climate and academic performance. However, the results show that PsyCap, positive emotions and study engagement have a mediating role between supportive study climate and academic performance. In addition, the findings reveal a multifaceted pattern among PsyCap, positive emotions and study engagement that promotes academic performance.

Originality/value
This is the first study that simultaneously explores the role of PsyCap, emotions and study engagement between supportive study climate and academic performance among university students. Consequently, it broadens and deepens previous research and offers both theoretical and practical implications.
Educated professionals of sustainability and the dimensions of practices
Authors: Salovaara Janne J. , Soini Katriina 
Published: April 2021

Purpose
The purpose of this paper is to expand the competence-led structuring and understanding of sustainability education by analysing the practices of professional individuals who have completed university education geared to the development of sustainability change-makers.

Design/methodology/approach
The research scope was initially on examining professional practices following the boundary work theory. Social practice theory was used as a methodological approach in conducting and analysing thematic interviews with 19 sustainability-focused master’s programme alumni. The interviews were analysed against the theoretical framework while also noting findings that fell outside of this framework.

Findings
A framework for understanding materials, competences and meanings of practices connected to the professional field of sustainability was introduced. The framework suggests that in the practices of sustainability-educated professionals, meanings emerge as a top priority and are conveyed using position-based materials and various complexes of competency.

Research limitations/implications
The authors suggest that boundary theory informs well the emergence of the professional field of sustainability, and the utilisation of a practice theory furthers the understanding of sustainability professionalism and its education.

Practical implications
The authors’ suggest that practice theory could thus provide deeper insights on how sustainability science alumni use their education after graduation, how they practice their profession and in return offer applicable reflections to sustainability education.

Originality/value
Research using practice theory in reflection on sustainability education and the professional practice of sustainability has not been widely conducted and in the authors’ opinion brings value to the education and practice of sustainability and to the research of sustainability education.
Building a hierarchical framework of corporate sustainability transition challenges using the qualitative information approach
Authors: Tseng Ming-Lang , Kurrahman Taufik , Hanita Asik , Lim Ming K. , Negash Yeneneh Tamirat 
Published: April 2021

PurposeThis study aims to form a valid measure and hierarchical framework to achieve corporate sustainability transitions (CSTs).Design/methodology/approachThe fuzzy Delphi method (FDM) is applied to validate and eliminate challenges in sustainability transition regarding qualitative information. Fuzzy interpretive structural modeling (FISM) is used to build a hierarchical framework under uncertainties.FindingsThis study finds that technology investment, data management, eco-management and sociospatial embedding challenges are the highest hierarchical framework levels and affect CST.Practical implicationsA lack of awareness and knowledge, a lack of commitment, a lack of strategy, tolerance of unsustainable practices, a lack of stakeholder participation and a fragmented market are perceived as the challenges that show the highest driving and dependence power. These challenges serve as a reference for government and construction firms in the transition to sustainable corporate practices.Originality/valueUnsustainable corporate practices have caused large amounts of energy consumption, resource depletion and environmental impacts. There are challenges in transitioning to corporate sustainability that must be addressed. The most significant challenges that need to be solved to facilitate the transition to corporate sustainability are identified and arranged in a hierarchical model. By identifying the hierarchical relationships among the challenges, a theoretical framework that extends the existing models is developed to assist decision-makers.
Why do consumers engage in online brand communities – and why should brands care?
Authors: van Heerden Danita , Wiese Melanie 
Published: April 2021

Purpose
The purpose of this paper is to explore consumers’ motivations for engaging in Facebook brand communities, and what outcomes brands can gain from online engagement.

Design/methodology/approach
An online consumer panel was used to collect data through convenience sampling; 497 useable questionnaires were collected.

Findings
The results of the structural equation modelling show that hedonic motivations are more prevalent in Facebook brand communities than utilitarian motivations. When considering the outcomes of online engagement, loyalty towards the brand community is the strongest outcome, followed by word-of-mouth and purchase intention.

Research limitations/implications
This research indicates that marketers should focus on creating content on Facebook brand communities that appeals to the hedonic needs of consumers, such as brand likeability, entertainment and interpersonal utility. This type of content will motivate members of these brand communities to engage online. When consumers engage online, it creates benefits for the brand such as loyalty, word-of-mouth and purchase intention.

Originality/value
This study presents a framework for investigating consumers’ motivation to engage online, based on a theoretical underpinning of both sense of community theory and uses and gratification theory. It also identifies three outcomes for brands that explain why it is worthwhile for firms to invest in engaging with consumers in Facebook brand communities while including a wide range of brand communities.
Right to health and access to health-care services for refugees in Turkey
Authors: Gokalp Aras N. Ela , Kabadayi Sertan , Ozeren Emir , Aydin Erhan 
Published: April 2021

PurposeThis paper aims to provide a comprehensive understanding of factors that contribute to refugees’ exclusion from health-care services. More specifically, using institutional theory, this paper identifies regulative pillar-, normative pillar- and cultural/cognitive pillar-related challenges that result in refugees having limited or no access to health-care services.Design/methodology/approachThe paper draws on both secondary research and empirical insights from two qualitative fieldwork studies totaling 37 semi-structured meso-level interviews, observations and focus groups in three Turkish cities (Izmir, Ankara and Edirne), as well as a total of 42 micro-level, semi-structured interviews with refugees and migrants in one large city (Izmir) in Turkey.FindingsThis study reveals that systematically stratified legal statuses result in different levels of access to public health-care services for migrants, asylum seekers or refugees based on their fragmented protection statuses. The findings suggest access to health-care is differentiated not only between local citizens and refugees but also among the refugees and migrants based on their legal status as shaped by their country of origin.Originality/valueWhile the role of macro challenges such as laws and government regulations in shaping policies about refugees have been examined in other fields, the impact of such factors on refugee services and well-being has been largely ignored in service literature in general, as well as transformative service research literature in particular. This study is one of the first attempts by explicitly including macro-level factors to contribute to the discussion on the refugees’ access to public health-care services in a host country by relying on the institutional theory by providing a holistic understanding of cognitive, normative and regulative factors in understanding service exclusion problem.
