The diversity of natural, climatic, and economic conditions of Russian regions implies a wide range of approaches to their classification. Simultaneously, the task of creating an abstract methodology ...for any branch of the national economy becomes more complicated. Effective clustering plays an important role in the establishment and implementation of agricultural and economic policies. The paper explores the potential of basic agricultural and economic regional clustering based on time series of main economic and agricultural development indicators. The dynamic segmentation technique was applied in order to monitor and predict the direction of meso-economic changes. Official Russian statistics were analysed to identify groups of indicators on production, production and institutional, and production and structural criteria. The k-means clustering algorithm was chosen as the key research method. Based on the three simulated regional segments, baseline average values were calculated. Then, the segments were classified according to the obtained characteristics. The outliers, significantly differing from the main data sets, were considered separately. The findings confirmed a wide spatial distribution of regions included in certain agricultural and economic segments. The presented classification can be applied to justify the directions and choice of instruments of agricultural and economic policy and a strategy for creating production clusters. Moreover, it can be used to plan the activities of regional agri-businesses and reduce their development imbalances. To improve the dynamic segmentation technique in the field of agricultural and economic development, the analysis can be expanded by changing the examined time interval, increasing the number of factors included in the model and their interactions, and introducing new clustering algorithms. Additionally, this model can be used to forecast structural changes and production dynamics.
This book explores the interrelated campaigns of agricultural collectivization in the USSR and in the communist dictatorships established in Soviet-dominated Eastern Europe. Despite the profound, ...long-term societal impact of collectivization, the subject has remained relatively underresearched. The volume combines detailed studies of collectivization in individual Eastern European states with issueoriented comparative perspectives at regional level. Based on novel primary sources, it proposes a reappraisal of the theoretical underpinnings and research agenda of studies on collectivization in Eastern Europe.The contributions provide up-to-date overviews of recent research in the field and promote new approaches to the topic, combining historical comparisons with studies of transnational transfers and entanglements.

No processo de concepçâo e introduçâo das tecnologías de precisāo em meio agrícola, há uma desproporçâo entre os aspectos de produtividade esperada e a atençâo prestada aos seus usos e aos seus ...efeitos na saúde dos agricultores. É esta dinámica que a ergonomia tenta restabelecer através da análise da atividade de trabalho. Neste artigo, questionamos, através da ergonomia, a agricultura de precisāo, os recursos que esta oferece aos agricultores, bem como as limitaçöes que provoca no trabalho real. Por fim, propomos recorrer à análise da atividade a diferentes níveis para acompanhar os agricultores ñas escolhas que tém de fazer e pensar de forma diferente a conceçâo e desenvolvimento destas novas tecnologías.
