Recently, much attention has been paid to the ideas and theories that highlight the cluster approach to the territorial organization of the economic system. Separation and development of transport and logistics cluster contributes to the development of competitive advantages, provides the leading position of the country in the world market and enhances the investment attractiveness of the region in which it operates. The use of a multidimensional statistical method of cluster analysis to determine the homogeneity between the individual regions of Ukraine contributes to the identification of transport and logistics cluster. For this reason, the article analyzes the role of cluster analysis in the study of the development of transport and logistics services, shows that the transport and logistics cluster is formed on the basis of the real socio-economic situation in the conditions of a particular territory, taking into account its potential development. It is substantiated that the transport and logistics cluster, in addition to meeting the needs of the economy, performs a number of important functions: it creates opportunities for the development of sectors of the national economy; contributes to the development of the region's infrastructure; increases the investment attractiveness of the region. The conducted research of existing methods of cluster analysis of grouping of regions of Ukraine by the level and potential of development of the market of transport and logistic services has allowed to allocate the considered ways of estimation of efficiency of functioning of the cluster which differ in external and internal effects. A cluster analysis of the territorial level and potential of logistics development in the regions of Ukraine is carried out on the basis of three groups of indicators (socio-economic, transport performance indicators of the region and indicators characterizing the composition of the transport system of the region and its potential opportunities). As a result of the cluster analysis, the regions of Ukraine were grouped into three clusters by the level of logistics development, and into two clusters by the logistics development potential. It is determined that the classification of regions into homogeneous groups will allow to build in each cluster typologically regressive equations of interaction of market factors, which will increase the accuracy of the study of the dynamics of the development of the market environment of regions of potential placement of elements of transport and logistics infrastructure.

This paper represents a pilot study examining entrepreneurial behavior patterns within the area of development of micro, small and medium-sized market active enterprises in South Moravian Region from the perspective of strategic management. The main aim of this article is to classify the enterprises by the character of development activities into relatively homogeneous groups and identify those activities that contribute to considerable differences between the individual groups. Empirical evidence is based on a quantitative survey in terms of a random choice of respondents obtained by means of an e-mail questionnaire. The major analytic procedure applied within this research comprises methods of Cluster Analysis and validation technique based on chi-square and G-square nonparametric tests for testing differences (independence) of variables between the clusters. By means of Cluster Analysis three relatively homogenous SME groups were identified. The first cluster, called “global”, (approximately 6% of the respondents) prevails in most of the strategic development aspects of the researched enterprises. Global SMEs rely on development activities in the area of product innovations and risk diversification into other activities. In terms of changes in functional strategies this involves primarily the area of new technology and human resources development, and the ability to benefit from participation in networks of cooperating organizations. The second cluster, called “transition”, (approximately 59% of the respondents) is developed mainly by means of investments in business specific knowledge, and/or in technical skills of their employees. They are more conservative in the area of product innovations and risk diversification into other activities, which is then reflected in a lower level of investments in technologies and marketing. In comparison with global enterprises the major difference lies in a much lower number of activities in the area of seeking cooperation with other enterprises. The third cluster, called “local”, (approximately 35% of the respondents) chooses the way of product innovations whose supply is mostly composed of standardized products and services, especially in local or regional markets. Local enterprises, when compared to the former clusters, are typical for a lower level of business cooperation, and in fact for absence of utilizing the support programs.

Abstract Background In this study we cluster the districts of India in terms of the spread of COVID-19 and related variables such as population density and the number of specialty hospitals. Simulation using a compartment model is used to provide insight into differences in response to public health interventions. Two case studies of interest from Nizamuddin and Dharavi provide contrasting pictures of the success in curbing spread. Methods A cluster analysis of the worst affected districts in India provides insight about the similarities between them. The effects of public health interventions in flattening the curve in their respective states is studied using the individual contact SEIQHRF model, a stochastic individual compartment model which simulates disease prevalence in the susceptible, infected, recovered and fatal compartments. Results The clustering of hotspot districts provide homogeneous groups that can be discriminated in terms of number of cases and related covariates. The cluster analysis reveal that the distribution of number of COVID-19 hospitals in the districts does not correlate with the distribution of confirmed COVID-19 cases. From the SEIQHRF model for Nizamuddin we observe in the second phase the number of infected individuals had seen a multitudinous increase in the states where Nizamuddin attendees returned, increasing the risk of the disease spread. However, the simulations reveal that implementing administrative interventions, flatten the curve. In Dharavi, through tracing, tracking, testing and treating, massive breakout of COVID-19 was brought under control. Conclusions The cluster analysis performed on the districts reveal homogeneous groups of districts that can be ranked based on the burden placed on the healthcare system in terms of number of confirmed cases, population density and number of hospitals dedicated to COVID-19 treatment. The study rounds up with two important case studies on Nizamuddin basti and Dharavi to illustrate the growth curve of COVID-19 in two very densely populated regions in India. In the case of Nizamuddin, the study showed that there was a manifold increase in the risk of infection. In contrast it is seen that there was a rapid decline in the number of cases in Dharavi within a span of about one month.

AbstractFarmer-based seed multiplication is widely promoted by development practitioners, but there is limited understanding of the individual or collective motivations of farmers to engage or disengage in specialised seed production. The objective of this study is to understand the factors influencing the continuity of sweetpotato vine multiplication enterprises in the Lake Zone of Tanzania, five years after support from a project ended. A total of 81 out of 88 trained group or individual decentralised vine multipliers (DVMs) were traced to assess their vine multiplication activities. Qualitative and quantitative data were collected through telephone and field interviews. Our data showed that 40% of the 81 DVMs had sold vines in the year prior to the study and 20% had maintained the improved varieties for their own use. Some group members had continued vine sales as individuals. The DVMs’ reasons for abandoning vine multiplication included climatic and water access issues, market factors and group dynamics. The DVMs did not engage in high volumes of commercial sales. Socio-economic norms and values underpin the transactions of sweetpotato vines. These norms may undermine the emergence of commercially viable enterprises yet seem navigable for a substantial number of the DVMs. Group DVMs seem less commercially successful than individuals.

Abstract For Moldova’s agriculture are characterized the existence of many small family farms and only a small number of corporate holdings (limited liabilities companies, agricultural production cooperatives etc). Most of individual farms, small by size produce only for own family consumption and cannot find their way to the market place. The accentuated poverty makes rural economy to flow more and more to a natural subsistence economy, isolating itself from the market economy. The goal of this paper is to delimitate different types of farms based on selected indicators and to appreciate their level of development. Differences in farms levels of development are appreciated through cluster analysis. The research includes the analysis of farms survey data. This research was carried as a part of the Academy of Sciences project “Sustainable rural development in Republic of Moldova in the context of EU accession”. In the project were surveyed 938 individual farms from nine districts across the country. As a result, we distinguish three types of farms: natural, family and market household. The cluster analysis allows to characterize the farms level development, to determine the main priority directions, and to elaborate measures for the individual farms further sustainable development.

In the rapidly growing literature on exploring urban restructuring in reference to the state rescaling, many authors have neglected the relatively fixed and immobile forms of territorial organization. The development of China’s National New Areas (NNAs) provides an opportunity to explore the hybrid and multiscalar processes of state rescaling. From the perspective of rescaling, an analytical framework was established to examine the practice of NNAs and their governance rescaling in China. Every National New Area (NNA) is the result of China’s “state spatial selectivity”, and the central government has guided policies to a specific spatial scale to cope with the development crisis. The rescaling of NNA governance is the process of the functioning of all-level administrative subjects in the functional orientation, spatial zoning, administrative system, and power allocation through rigid or flexible means. In practice, there are significant governance scale differences in territorial spatial organization, administrative systems, and power distribution among the various NNAs, which has led to diverse governance modes. The degree of coupling between the scale of new and existing administrative divisions is the key to the rescaling of NNA governance. Most NNAs are still facing the challenge of unifying their territorial development logic. Discussions of state rescaling in western countries have focused on the super-local level. The case of China clearly shows the role of local embeddedness and diversification in rescaling.

The quality of grapes is determined above all by the contents of the primary and secondary metabolites. The primary metabolites involve sugars and organic acids, and just these compounds are dealt with in this study. Its objective was to analyse and critically evaluate the primary metabolites in new interspecific varieties and, based on a comparison with European varieties of grapevine (Vitis vinifera L.), to find out the similarities and also possible differences between them. The study evaluates and compares 4 conventional varieties of Vitis vinifera with 11 new interspecific cultivars. The contents and compositions of the individual sugars and acids were estimated by means of the HPLC method. Most of these varieties belong to the group with either medium or low content of malic acid, i.e. with a medium to high &beta; ratio. This corroborates the similarity of interspecific varieties to those of V. vinifera. The cluster analysis identified the existence of two interesting groups of varieties: the first one involved the varieties Riesling, Nativa, Marlen, and Kofranka while the other group consisted of varieties Blaufr&auml;nkisch, Blauer Portugieser, and Laurot. This observation also indicates similarity between Vitis vinifera L. varieties and interspecific cultivars and demonstrates that the contents of the primary metabolites (i.e. sugars and organic acids) are also comparable.
