Incomplete definitions of geodiversity and geoheritage caused the domination of clearly geological approach to these scientific problems. That is the reason why some of the integral elements of geographical environment were neglected. Wrong theoretical assumptions reflected negatively the determination and advancement of this scientific discipline. The reasons for such condition are mentioned in the paper, as well as the necessity of different and more comprehensive perspective of geodiversity and geoheritage, by which the directions of the future development are implied. .

<p>Agroecology – as a scientific discipline and as an approach to sustainable farming practice – has objectives similar to those of organic agriculture. The paper sharpens the profile of both concepts and identifies strengths and weaknesses. The overarching challenge of both is to minimize trade-offs between food and fiber production on the one hand and non-commodity ecosystem services on the other hand. A comparison of the two approaches may well be inspiring, especially for the future development of organic food systems.</p> <p>Best use of human, social and natural capital characterizes organic farmers, especially in developing countries, as documented by many case studies from sub-Saharan Africa. That also applies to organic farms in temperate zones, although usually more external inputs are used in organic farming there. While the profitability of organic farms is comparable to or slightly higher than that of conventional ones, per area food production is lower by an average of 20 to 25 percent in temperate zones. Overly restrictive production standards are often mentioned as the cause, but also a lag in production techniques. One of the main approaches of organic agriculture to augment productivity is ecological or eco-functional intensification. Thereby, the goal is to maintain the ecological and social qualities of the farms and to increase food output. The future development of organic agriculture can be characterized by a comprehensive culture of innovation embracing social, ecological and technological innovations. Such a concept of innovation includes dynamic interactions between farmers and scientists in order to strengthen system resilience and make better use of basic research from a wide range of scientific disciplines.</p>

Heterogeneity studies have analyzed different clusters of residents according to their perception and attitude toward tourism in general or a specific type of tourism, but there are still no studies on the heterogeneity in the acceptance of tourist offers. The aim of this article was to segment residents according to their acceptance of different tourist offers focused on the territory. This is a new approach that seeks to determine the profiles of residents based on their preferences for the future development of a destination’s offer in order to solve land-related problems. Cluster analysis carried out by the K-means algorithm made it possible to create five clusters: Disappointed, favorable with nuances, moderate, enthusiasts but anti-nightclub, and enthusiasts. The clusters were characterized by the rejection of the “all inclusive” offer and by the acceptance of most offers. The types of tourism that involve an enhancement of the landscape and heritage were shown to be the best valued. The differences between the clusters were marked by the degree of general acceptance and by the rejection of some offers considered “conflicting.” The offers that imply a high consumption of land (golf courses) or annoyances from the immediate surroundings (nightclubs) generated discrepancies.

The article examines the state of the Holocaust historiography in Ukraine for the period of 2010 – beginning of 2014. The review analyzes activities of major research and educational organizations in Ukraine which have significant part of projects devoted to the Holocaust; main publications and discussions on the Holocaust in Ukraine, including publications of Ukrainian authors in academic European and American journals. The article illustrates contemporary tendencies and conditions of the Holocaust Studies in Ukraine, defines major problems and shows perspectives of the future development of the Holocaust historiography in Ukraine.

This paper,first presented on 21 October 1995 at ajoint seminar ofthe Scottish Law Commission and the Faculty of Law, University of Edinburgh, on the subject of breach of contract, considers the future development of the law in this area, first by considering its history and current state in comparative terms and drawing the conclusion that it is characterised by a mixture of Civilian and Common Law elements; second, by comparing Scots law with the provisions on breach contained in recently published proposals for a harmonised law of contract (the UNIDROIT Principles of International Commercial Contracts, the Principles of European Contract Law prepared by the Lando Commission, and the draft “code”for the United Kingdom prepared on behalf of the English Law Commission by Harvey McGregor in the late 1960s) and in international conventions on the sale of goods. Although Scots law emerges reasonably wellfrom this exercise, there are a number of points to be taken on board in any future reform, as well as some insights into important underlying principles.

A practical and concise total synthesis of tricyclic ketone 7 (CDE ring), a valuable intermediate for the synthesis of racemic camptothecin and analogs, was described (8 chemical steps and 29% overall yield). The synthesis starts with two inexpensive, readily available materials and is operationally simple to perform. It is worth mentioning that the reported protecting group-free synthesis, with advantages of a short route, would be helpful for the future development of industry-scale syntheses of camptothecin-family alkaloids.
