BACKGROUND: Blackcurrants are an important berry crop whose further development depends mainly on the diversity of available plant material and its successful inclusion in the breeding. OBJECTIVE: The study aimed to evaluate selected SSR markers’ applicability for the analysis of germplasm consisting of genotypes developed through complicated multistage crosses among different Ribes species and estimate the genetic structure and level of genetic diversity of the blackcurrant collection. METHODS: The set of 110 blackcurrant accessions from the Latvian genetic resources collection was genotyped using 18 previously described SSR markers. RESULTS: The marker set provided all genotypes with unique fingerprints and proved the need for reference genotypes in international studies for data validation. The accessions clustered according to pedigree and did not group by country of origin or breeding programme. CONCLUSIONS: The tested SSR markers uncovered relationships between blackcurrant accessions of complicated interspecific composition and revealed an extensive mutual exchange of germplasm among breeding programmes, thus pointing to the need for new donors of valuable characteristics. The results also highlighted the necessity to identify each species’ proportion in the hybrid material to assess the impact of species-linked gene expression.

Purpose. The aim of the article is theoretical substantiation of the essence of investment attractiveness, analysis of trends and identification of opportunities for further development of agro-industrial enterprises. Methodology of research. General and special methods are used during the research, in particular: monographic and systematic analysis – to substantiate the essence of investment attractiveness and to determine the possibilities of further development of agro-industrial enterprises; abstract and logical and graphic – in forming the conceptual bases for investing in the development of enterprises. Findings. The essence of investing in the development of enterprises as a system of actions to attract real and potential internal and external investment resources, sources, levers and measures, taking into account the institutional and factor influence on the given course of investment processes in the short, medium and long term, is determined on the basis of generalization of scientific approaches which leads to qualitative, quantitative and structural changes in the production and economic activity of agro-industrial enterprises on an innovative basis, achieving a high result in the case of coordination and consolidation of efforts of business structures and bodies of state power and local self-government, solving problems and prioritizing investments by the nature of strategic orientation. The necessity of providing investment development of enterprises is considered taking into account the influence of peculiarities of investing material, intangible and bioactive assets on an innovative basis, which determine the scientific theoretical and methodological approaches and applied aspects, strategic importance of the basic and life-supporting branch of the national economy. The rating positions of the investment attractiveness of Ukraine in the international studies of the economic development of the countries are revealed as rather weak and not the best. However, at the same time, it is revealed that Ukraine has significant investment and human potential, the effective use of which may be a prerequisite for gradual enhancement of the country's international competitiveness in world rankings. We believe that global international rankings should be seen as additional tools for making investment decision. It is determined that at present the most pressing problem for foreign investors remains the protection of their rights and the ability (easiness) of doing business. Therefore, the efforts of the state should be directed to solving problems in the commercial sphere and forming a favourable business environment, increasing investment in the agricultural sector, stabilizing sources and optimizing capital structures, ensuring efficient distribution of investments in the formation of assets of agricultural producers by their size. Originality. The definition of the essence of investing in the development of agro-industrial enterprises has been further developed; the scheme of conceptual bases for ensuring the investment attractiveness and opportunities for further development has been formed, taking into account the impact of the current global economic recession. Practical value. The results of the study can be used to expand the base, diversify sources and increase the volume of investment with the introduction of the land market, in the process of creating and commercializing innovations and activation of innovative development of agro-industrial enterprises, the main priorities of which should be the realization of internal production factors. Key words: investments, innovations, development, enterprise, attractiveness, commercialization, efficiency.

The burden of caregivers has been intensively researched for the past 30 years and has resulted in a multitude of individual findings. This review illustrates the significance of the hypothetical construct of perceived burden for the further development and design of the homecare situation. Following explanations regarding the term informal caregiver, we derive the construct burden from its conceptual association with the transactional stress model of Lazarus and Folkman. Once the extent and characteristics of burden have been set forth, we then present the impact of perceived burden as the care situation. The question of predictors of burden will lead into the last section from which implications can be derived for homecare and relief of caregivers.

This paper seeks to investigate sustainable cross-border cooperation (CBC) as a distinctive model of interstate collaboration, embedded in the neighboring borderland regions of two or more countries. The focus of the research revolves around the establishment and further development of geostrategic, economic, cultural and scientific capacity of the Ukrainian-Romanian partnership as a fundamental construct in ensuring and strengthening the stability, security and cooperation in Europe. This research highlights Ukraine’s aspirations to establish, develop and diversify bilateral good-neighborly relations with Romania both regionally and internationally. The main objective is to elucidate Ukraine-Romania cross-border cooperation initiatives, inasmuch Ukraine-Romania CBC has been stirring up considerable interest in terms of its inexhaustible historical, cultural and spiritual ties. Furthermore, the similarity of the neighboring states’ strategic orientations grounds the basis for development and enhancement of Ukraine-Romania cooperation. The authors used desk research and quantitative research to conclude that Ukraine-Romania CBC has the impact not only on the EU and on Ukraine multi-vector foreign policy, but it also has the longer-term global consequences. In the light of the current reality, the idea of introducing and reinforcing the importance of Cross-Border Cooperation (CBC) sounds quite topical and relevant. This research considers a number of explanations for Ukraine-Romania Cross-Border Cooperation as a key element of the EU policy towards its neighbors. Besides, the subject of the research is considered from different perspectives in order to show the diversity and complexity of the Ukraine-Romania relations in view of the fact that sharing common borders we are presumed to find common solutions. As the research has demonstrated, the Ukraine-Romania cross border cooperation is a pivotal factor of boosting geostrategic, economic, political and cultural development for each participant country, largely depending on the neighboring countries’ cohesion and convergence. Significantly, there is an even stronger emphasis on the fact that while sharing the same borders, the countries share common interests and aspirations for economic thriving, cultural exchange, diplomatic ties and security, guaranteed by a legal framework. The findings of this study have a number of important implications for further development and enhancement of Ukraine-Romania cooperation. Accordingly, the research shows how imperative are the benefits of Romania as a strategic partner for outlining top priorities of Ukraine’s foreign policy.

Theory Of Production

The article examines the impact of the discourses concerning idleness and food on the formation of “production art” in the socio-political context of revolutionary Petrograd. The author argues that the development of the theory and practice of this early productionism was closely related to the larger political, social and ideological processes in the city. The Futurists, who were in the epicenter of Petrograd politics during the Civil War (1918–1921), were well acquainted with both of the discourses mentioned, and they contrasted the idleness of the old art with the dedicated labor of the “artist-proletarians” whom they valued as highly as people in the “traditional” working professions. And the search for the “right to exist” became the most important goal in a starving city dominated by the ideology of radical communism. The author departs from the prevailing approach in the literature, which links the artistic thought of the Futurists to Soviet ideology in its abstract, generalized form, and instead elucidates ideological influences in order to consider the early production texts in their immediate social and political contexts. The article shows that the basic concepts of production art (“artist-proletarian,” “creative labor,” etc.) were part of the mainstream trends in the politics of “red Petrograd.” The Futurists borrowed the popular notion of the “commune” for the title of their main newspaper but also worked with the Committees of the Rural Poor and with the state institutions for procurement and distribution. They took an active part in the Fine Art Department of Narkompros (People’s Commissariat of Education). The theory of production art was created under these conditions. The individualistic protest and “aesthetic terror” of pre-revolutionary Futurism had to be reconsidered, and new state policy measures were based on them. The harsh socio-economic context of war communism prompted artists to rethink their own role in the “impending commune.” Further development of these ideas led to the Constructivist movement and strongly influenced the extremely diverse trends within the “left art” of the 1920s.

The Impact

Drought stress is considered a severe threat to crop production. It adversely affects the morpho-physiological, biochemical and molecular functions of the plants, especially in short duration crops like mungbean. In the past few decades, significant progress has been made towards enhancing climate resilience in legumes through classical and next-generation breeding coupled with omics approaches. Various defence mechanisms have been reported as key players in crop adaptation to drought stress. Many researchers have identified potential donors, QTLs/genes and candidate genes associated to drought tolerance-related traits. However, cloning and exploitation of these loci/gene(s) in breeding programmes are still limited. To bridge the gap between theoretical research and practical breeding, we need to reveal the omics-assisted genetic variations associated with drought tolerance in mungbean to tackle this stress. Furthermore, the use of wild relatives in breeding programmes for drought tolerance is also limited and needs to be focused. Even after six years of decoding the whole genome sequence of mungbean, the genome-wide characterization and expression of various gene families and transcriptional factors are still lacking. Due to the complex nature of drought tolerance, it also requires integrating high throughput multi-omics approaches to increase breeding efficiency and genomic selection for rapid genetic gains to develop drought-tolerant mungbean cultivars. This review highlights the impact of drought stress on mungbean and mitigation strategies for breeding high-yielding drought-tolerant mungbean varieties through classical and modern omics technologies.

This paper focuses on the dynamic of the recent upheaval in the tourism and hospitality sector due to the COVID-19 epidemic in Greece and Santorini island. It uses the case study of a country one-fourth of whose GDP consists of tourism. We compare the available statistical data showing the change in variables in the previous years with 2020 and look into the new challenges and opportunities posed by the drop in the numbers of visitors and flights. We focus mainly on the economic and social impact on the destination and possible future scenarios for further development in the area. Data show a significant effect of the pandemic on multiple variables, such as the long-term trend of the importance of tourism sector in GDP in Greece, the number of flights and visitors to Greece and Santorini island, and the contribution of tourism and travel to GDP. Based on the available data, we also construct three foresight scenarios that describe the possible futures for Santorini island in terms of the pandemic evolution. These scenarios may help various stakeholders and policymakers to be better prepared for different developments that may appear.

The Impact

Current use of reproductive technology in the Australian livestock industries is limited, though it increased in line with higher prices for beef and wool through the 1980s. The required techniques, many of which were developed in Australia, are available and the level of expertise is comparable to the best in the world. However, the extensive pastoral industries do not readily lend themselves to these procedures. Only in the dairy industry is artificial insemination used to a significant degree. On the other hand, application of the technology in the pastoral industries is confined largely to studs and breeding cooperatives which provide breeding animals for producer flocks and herds. Hence the impact of applied technology may be more widespread than first appears. Until recently, little regard was paid to application of the technology along sound breeding principles. Artificial insemination and multiple ovulation and embryo transfer (MOET) have not been used so much in planned breeding programmes aimed at local improvement of stock, but more to proliferate genes of reputedly superior stock, imported either from overseas or elsewhere in Australia. This is particularly true of MOET, where the incentive to use it is commonly a short term cash gain made from proliferating breeding stock of a particularly valuable and usually novel strain or breed. Recent technological improvements which render the use of reproductive technology cheaper and more effective will lead to its more widespread use in commercial practice. Techniques for embryo freezing and splitting have been greatly simplified and quickly put into practice. The novel livestock technologies of in vitro oocyte maturation and fertilization have already found commercial application overseas. Fecundity-enhancing products have also been adopted by the livestock industries. There is potential value for greater use of reproductive technology in the livestock industries provided it is implemented according to sound breeding principles and provided associated management practices are applied simultaneously.

Insight Into

The evaluation of design concepts is a time consuming and resource intensive process. Crowdsourcing evaluations has been examined in previous work as a means to reduce the need for expert raters, while achieving similar evaluation results. This paper examines the impact of empathically priming novice raters on their evaluation of alternative design concepts. The rating system is based on a pairwise comparison method that requires minimal training of novice raters. In a pilot study the pairwise method for crowdsourcing evaluations is compared with crowdsourced evaluations using non-pairwise rating scales and with the evaluations of expert raters. The primary study incorporates written and empathic priming strategies to determine their impact on novice raters’ evaluation of concepts. Raters are asked to consider several criteria, including novelty, feasibility, clarity (of the concept), usefulness, ease of use, and overall worthiness of further development. Results offer insight into the criteria that are most relevant to novice raters and whether empathic priming has a significant effect on those evaluations.
