Background: In Brazil, Swartzia Schreb. occurs in almost all phytogeographic domains, but the greatest richness of species is concentrated in the Amazon. Question: What are the morphological and anatomical variations of the seeds of species of the Swartzia? Studied species: Swartzia laevicarpa, Swartzia macrocarpa, Swartzia recurva, and Swartzia sericea. Study site and dates: The species were collected in the Sustainable Development Reserve of Tupé - AM Brazil, in 2017 and 2018. Methods: Cross-sections of the seed coat were cut, to observe the characteristics of the seed coat in the hilar region and opposite it. Histochemical tests were performed on the cross-sections of fresh samples, to verify ergastic substances present in the aril, seed coat and cotyledons. Results: The seeds have a smooth and membranous seed coat, partially covered by a spongy aril in Swartzia recurva, filamentous in S. laevicarpa, S. sericea, and S. macrocarpa. Linear hylum, imperceptible micropyle, cryptoradicular embryo, fleshy cotyledons, containing starch, lipids, alkaloids, protein and the rudimentary plumule. Conclusions: Morphological characteristics of the seed, such as shape, color, consistency of the aril and size of the hilum, are important diagnostic characters in the recognition of this species in the field, through its respective seeds; in the same way, the information on soil seed bank is expanded. The presence of fleshy cotyledons indicates and adaptation to the type of environment in which these species occurs, while the knowledge of ergastic substances present in the aril, seed coat and cotyledons, contributes to the understanding of their germinative processes.

The Covid-19 induced economic crisis has significantly affected almost all businesses from nearly every sector, causing severe financial problems, lack of cash assets, and decrease of revenues. In this context, the economic entities were forced to look for adjustment and rescue solutions of their activities. One possible solution for the recovery and reorganization of economic entities’ activities is demerger. This paper evaluates the impact of demerger upon the sustainable development of economic entities in terms of economic efficiency and financial performances. To achieve this goal, a statistical analysis of profitability ratios before and after the demerger, as well as a structural analysis of 268 demerger projects for the April 2012–April 2021 period, were performed. The results attest there are no significant differences between the ex-ante and ex-post financial performances. However, demerger seems to have a positive effect upon analyzed companies helping them to overcome economic hardships, rethink their business strategies, and continue their activity in the medium and long-term time horizon.

As a new species in the financial ecosystem, internet finance has significantly impacted traditional finance and has improved the diversity and ended the long-term stability of the financial ecosystem. From the perspective of the interaction between the ecological subjects of the Internet and traditional finance, this study examines the influence of internet finance on the sustainability of the financial ecosystem in China. We tested the dynamic correlation and risk transmission at the volatility level between the ecological subjects of internet finance and the banking, securities, and insurance industries by establishing a dynamic conditional correlation-generalized autoregressive conditional heteroskedasticity (GARCH) model of Baba, Engle, Kraft, and Kroner (DCC-GARCH-BEKK). The result indicates a positive dynamic correlation between internet finance and traditional finance almost all of the time. The introduction of internet finance has changed the risk transmission effect among the ecological subjects of traditional finance. Based on empirical findings, this study provides suggestions to promote the sustainable development of internet finance and the whole financial ecosystem. Our research not only has strong practical significance but also contributes significantly to the literature on internet finance and sustainable development.

Sustainability ideas are implemented in almost all areas of life, not only into the economic and social life. However, the ways to sustainable development quantifying are still relatively complicated and incomplete. One of the possibilities of assessment and achievement of sustainable development and sustainability can be considered assessment using the Sustainable Development Goals (SDGs) presented in Agenda 2030. The aim of the paper is to assess the similarity of the EU countries in achieving the Sustainable Development Goals according to 2030 Agenda.

Abstract Nowadays, principles of the sustainable development concept are present in almost all areas of life, play a key role in efforts to protect the environment, activities for the community and economic development. One of the "beneficiaries" of this concept are the enterprises, both small local as well as those with a global reach. In almost every operating company, in a greater or lesser extent, pillars of sustainable development are used, but before this happened - these companies have to go through a few steps, that led to the full implementation of the sustainable development concept and its application in practical terms. This article presents and describes in detail, the various stages of completion of which is the existence and the practical use of the sustainable development concept in its activities.

Aim: As one of the biggest organisations in the world, the National Health Service (NHS) in England can contribute considerably to the United Nations’ Sustainable Development Goals (UN’s SDGs). In order to optimise this, this study evaluated and reconceptualised a sustainable development assessment tool for health and care settings in England. Methods: A quantitative survey and user/expert discussion panels were conducted to evaluate and reconceptualise the existing sustainable development assessment tool used by the NHS in England, the so-called ‘Good Corporate Citizenship Assessment Tool’, including potential improvements such as the integration of the UN’s SDGs. Results: A reconceptualised self-assessment tool integrating the UN’s SDGs was developed and implemented online as the ‘Sustainable Development Assessment Tool’ (SDAT). Further improvements included a process-oriented redesign and the creation of new modules and cross-sections aligning them with the leads responsible for the implementation of key initiatives in NHS organisations, which would contribute to achieving the targets of the SDGs. Conclusion: User/expert involvement has enabled an informed approach to a reconceptualisation of a sustainable assessment tool for health and care settings. The tool will support organisations to build their mandatory Sustainable Development Management Plans, as part of the National Public Health Outcomes Framework. Alignment of the tool to the UN’s SDGs provides an opportunity for health and care organisations to demonstrate accountability and progress against the UN’s set of transformational goals. Furthermore, the tool could be adapted to other public service providers.

In this paper, we present the morphological characteristics of the seed and micromorphological, anatomical and chemical characteristics of the seed coat of pea (Pisum sativum L.) genotypes, Jezero, Javor and NS Junior. Our aim was to investigate whether these genotypes can be differentiated based on seed coat morphoanatomical characteristics, depending on the harvest treatment. The observations and measurements of seed coat cross-sections were performed using light microscopy. The seed coat surface was observed using SEM. A tuberculate seed coat surface characterized all examined pea genotypes, and the average diameter of the tubercle was about 12 ?m. Statistical and laboratory analyses revealed that major damage was the most frequent defect type as the result of mechanized harvest in all the examined genotypes. Genotype NS Junior had the shortest seed length (6.1 mm). Micromorphological analysis revealed that the seed surface was tuberculate in all genotypes. The genotype Jezero had the highest number of tubercle ribs (11.0) and a significantly higher proportion of parenchyma tissue (50.6%), while NS Junior was characterized by the greatest share of macrosclereids (49.8%). The highest number of osteosclereids (832/mm2) was counted in genotype Javor. In addition, genotype NS Junior stands out due to the highest percentage of crude fiber (62.75 g/100g) in the seed coat. There was a marked difference among the studied genotypes with regard to the seed coat morphoanatomical characteristics, which is confirmed by the results of multivariate discriminant analysis (MDA). These results suggested that the morphological, micromorphological and anatomical characteristics of the seed might have an impact on the seed coat damage level at harvest.

The socio-economic processes in the world and in Europe are highly dynamic and are aimed at a sustainable development of society. The sustainable and balanced development of society determines the need for the development of coherent and objectively justified elements of the legal system, including the creation of a new legal framework, the permanent reform of law enforcement authorities, and the use of national and international legal practices in socio-economic activities. At present the sustainable development of society is affected by a new socially unfavourable phenomenon COVID-19  that has a global impact on all regions of the world and almost all spheres of life. International organizations and national institutions must be responsible, courageous and determined in tackling the challenges of the crisis and in building a new generation. The global crisis can be a unique opportunity not only to successfully overcome its consequences, but also to ensure a transition to a fair, climate-neutral and digital sustainable Europe. In this context innovative thinking, successful use of modern technologies, transition to new models of social, economic, political and legal governance are needed. In general, this will contribute to the development of the sustainable society based on a full legal framework. Research aim: to identify the current state of the sustainable development of society, including the impact of COVID-19, by modelling the potential development of it, in accordance with the perspective of transnational socio-economic development. Research methods: study of legal literature and literary sources, the Internet resources, method of modelling, as well as descriptive and analytical methods.  Keywords:  COVID-19, sustainable development, crisis, society, the legal framework

Whether smartphone, smart home or smart city—digitalisation determines almost all areas of our lives today. The topic of sustainability is also omnipresent in 2019 and numerous challenges associated with it are currently being discussed. Digitalisation and sustainability can thus be regarded as the two megatrends of the 21st century. The question of whether digitalisation is an instrument for achieving sustainable development is increasingly at the centre of the debate. The Sustainable Development Goals (SDGs) developed by the United Nations as part of the 2030 Agenda are of particular interest for assessing digitalisation as a potential means of achieving sustainable development. With the help of empirical work by students from the University of Kaiserslautern, this edited volume provides answers to the question of how different digital technologies can help to achieve these 17 goals.

This article presents methodology of land use change assessment in the context of sustainable development and the results of its application based on the transformations that occurred in individual areas of Europe in the years 2012–2018. This method is based on data from the CORINE (CO-oRdination of INformation on Environment) Land Cover program) and local government units presenting the degree of urbanization (DEGURBA). The transformations taking place in space were evaluated and reduced to economic, social, and environmental dimensions. We then analyzed the results in terms of space (covering almost all of Europe) and in terms of division (large cities, small towns, suburbs, and rural areas). Results indicate that development of the economic dimension most often takes place at the expense of natural resources. It was also determined that the higher the population density, the greater the sustainable development differentiation level in the analyzed dimensions, of which the social dimension was characterized by the lowest differentiation and the economic dimension was highest. The development of rural areas was found to be less sustainable than large urban centers. Interpretation of the results also leads to the conclusion that areas of Europe are very diverse in terms of sustainable development. However, the method itself, despite the imperfections observed by the authors, may be used in further or similar studies.
