Environmental Impact of Construction Products on Aquatic Systems—Principles of an Integrated Source–Path–Target Concept

Buildings exposed to water can release undesirable substances which, once transported to environmental compartments, may cause unwanted effects. These exposure pathways need to be investigated and included in risk assessments to safeguard water quality and promote the sustainability of construction materials. The applied materials, exposure conditions, distribution routes and resilience of receiving compartments vary considerably. This demonstrates the need for a consistent concept that integrates knowledge of emission sources, leaching processes, transport pathways, and effects on targets. Such a consistent concept can serve as the basis for environmental risk assessment for several scenarios using experimentally determined emissions. Typically, a source–path–target concept integrates data from standardized leaching tests and models to describe leaching processes, the distribution of substances in the environment and the occurrence of substances at different points of compliance. This article presents an integrated concept for assessing the environmental impact of construction products on aquatic systems and unravels currently existing gaps and necessary actions. This manuscript outlines a source–path–target concept applicable to a large variety of construction products. It is intended to highlight key elements of a holistic evaluation concept that could assist authorities in developing procedures for environmental risk assessments and mitigation measures and identifying knowledge gaps.

The legitimacy of corporate entrepreneurship: a structured literature review

Corporate entrepreneurship (CE) is essential for today’s firms and currently a topic of considerable interest within the business community. Although the magnitude of related studies has increased over the last years, research on CE is missing an integrated concept and a research agenda for understanding the dynamics of resource deployment and withdrawal, resulting from legitimacy within the organization. The objective of this study is to examine the determinants influencing the provision and withdrawal of resources in the context of corporate entrepreneurship and identify the underlying strategies for gaining legitimacy. Analyzing more than 30 years of research, we provide a multidimensional framework synthesizing the state-of-the-art of resource allocation and withdrawal in CE. Our findings suggest that CE entities undertaking legitimation efforts, to be perceived as a meaningful and trustworthy organizational element and receive active and passive support, is very important. Based on the structured literature review, we propose a legitimacy perspective on the resource dynamics in CE settings, to further advance our understanding of resource deployment and withdrawal within organizations.

URBAN DEVELOPMENT OF RESIDENTIAL AREAS IN THE CITY OF CHERNIVTSI

The territorial development of the city is studied on the basis of town-planning documentation and full-scale researches of residential and former industrial territories, the factors which have formed the basis of the concept of the general plan of development of the city are resulted. Options for the transformation of territories occupied by industrial enterprises are considered. The integrated concept of city development is analyzed, in particular, conversion proposals of development and improvement and modernization of abandoned territories of non-functioning and partially functioning industrial enterprises, the concept of residential development is analysed. The city of Chernivtsi in its economic and geographical location is an industrial, administrative and cultural center of the region, with a large historical and architectural heritage. Due to the growing demand for living space and the diversification of forms of housing, the intensive development of the city is becoming more expressed. Aspects of land consolidation are not yet a priority, however, thanks to a quality planning policy, sustainable development of the city can still be achieved. Newly built areas are characterized by a high level of compaction. The study of the territorial development of the city can lead to a better balance in the use of land resources, options for the transformation of the territories of former industrial zones and enterprises that are partially functioning in these areas or abandoned and liquidated. The application of the principles of sustainable urban development according to the European model has been further developed, the integration of the housing function into industrial areas has been improved on the example of the town-planning proposal for the development of former industrial zones. The city is constantly expanding. There is a tendency to build large-scale buildings outside the old town and traditional suburbs, which are not typical for this area, especially multi-storey residential and retail facilities. Their inclusion in the general structure of the city by type (function) and size (form) in accordance with the context of urban development is not observed. At the same time, the territory of the city on the outskirts is constantly increasing, which leads to further use of natural spaces and maximizing the distance to public and commercial institutions, as well as workplaces, due to which the ammount of traffic increases. Territorial development of the city is a consequence of the general concept of the general plan of development of the city on the basis of the factors which have formed its basis. These include: The concept of economic development of the city, which is based on a market economy and private initiative, the priority development of the service sector, the development of the tourism and leisure industry. Population dynamics. Hence the output of the quantitative indicator of the required areas. Planning constraints, environmental protection and rational use of natural resources. Available territorial resources and efficient use of territories. The concept of three-dimensional composition, planning structure and functional zoning of the city. Rational system of resettlement in relation to places of employment. A number of territories, which have a very favorable position in relation to the places of employment, to transport connections due to one reason or another have not been developed - complex engineering training, lack of networks, the presence of other restrictions. All areas are partially occupied by individual manor buildings. The master plan envisages the development of these areas by 2032 without access to agricultural land. The article also discusses the options for the transformation of the territories occupied by industrial enterprises. These options can be as follows: Change in the functional purpose of the territory due to the removal or closure of industrial enterprises that adversely affect the environment. Technical re-equipment of the enterprise on new technologies (with preservation of a profile) for the purpose of reduction of harmful influence on environment. Replacement of the profile or functional use of real estate due to the bankruptcy of the enterprise. As a result of field surveys of residential and industrial areas of the city and research of urban planning documentation of the city of Chernivtsi and the Integrated Concept of Urban Development, the former industrial areas of the city were also analyzed. During the survey of all districts of the city, old industrial areas were identified, which today, due to significant use and a favorable location within the city, need to be improved and modernized. According to the Integrated Concept of City Development, conversion proposals for the development and improvement and modernization of abandoned areas of non-functioning and partially operating industrial enterprises were provided.
