In this study, the authors have investigated the determination of the most suitable legal form for the development of the cluster management activities. In each particular case the developers of the cluster have to assess the objectives of the cluster, the principal aspects of the mutual partnership, the risks that could be provoked, and in accordance with the derived decisions. The choice of the cluster legal activity form depends on the objectives and on the branch in which the cluster is operating, on the number of the cluster participants, on the type of the activities of the cluster, on the openness or closeness to new members, type of the contributions of the partners and the other factors. The most reliable solution regarding the choice of the model of the functioning and management of the cluster has to be derived as well legal regulation of the legal form of the activity discussed. The advantages and disadvantages of two models of the cluster formation discussed. During experimental evaluation, the significance of criteria was determined and the expert evaluation on legal form for the * This research was supported by the project,which has received funding from the

Research background: technology development and its application for human activities — R&D — have been recognized as the basis of economic performance, a source of technological solutions and of high value-added supply both in scientific literature as well as in the strategic documents of the Government and international organizations. In order to ensure the harmonious activity of the institutions engaged in R&D and to reduce the uncertainty of the commercialization of technologies, an advanced tool for verifying decisions on technology development at early stages of commercialization, i.e. an instrument for assessing the commercial potential of technology, is needed. Over the last decade, the analysis of the tools on a global scale led to the unequivocal conclusion — so far developed methodical basis has suffered from lack of maturity for its practical use in business, a need for assessing commercial potential at an early stage of technology commercialization has been ignored, and the assessment of commercial potential has not considered the specificity of high technology. Purpose of the article: This article discusses in detail the preparation and application pro-cesses of the model for assessment the commercial potential of high technologies. Methods: in the model the multiple criteria method is applied the selection of which was determined by the motive related to the goal of assessment — assess the commercial potential of high technologies. Findings & Value added: The essence of scientific novelty embraces the creation of a qualitatively new, original, science-based model for assessing the commercial potential of technologies thus flexibly applying it to assessing different levels of technologies. The original model is based on: the focus on the specificity of high technologies in assessment the commercial potential of technologies; the focus on the early stage of technology commercialization by assessing the commercial potential of technologies; flexibility in the application of the model taking into account the technological level, legal status, opportunity to assess the commercial potential of technologies in different countries and institutions; mathematical calculations based on assessing commercial potential.

Green products, clean energy, energy union, green buildings, eco-innovations, environment-related, and similar initiatives and policies have become very popular and widely applied all over the world. A pleasant built environment (parks, flowerbeds, beautiful buildings) and a repulsive environment (noise, polluted surroundings) influence a buyer’s outlook on an advertisement differently. An aesthetic, comfortable, and clean built environment evokes positive emotional states, not only at the time of housing selection and purchase but during the building’s life cycle as well. Potential housing buyers always feel comfortable in certain built environments, and they are inclined to spend more time there. The issues needing answers are how to measure the segmentation/physiological indicators (crowd composition by gender and age groups), as well as the emotional (happy, sad, angry, valence) and physiological (heart rate) states of potential homebuyers realistically, to produce an integrated evaluation of such data and offer buyers rational, green, and energy efficient housing alternatives. To achieve this purpose, the Multisensory, green and energy efficient housing neuromarketing method was developed to generate the necessary conditions. Here, around 200 million multisensory data recordings (emotional and physiological states) were accumulated, and the environmental air pollution (CO, NO2, PM10, volatile organic compounds) and noise pollution were investigated. Specific green and energy efficient building case studies appear in this article to demonstrate the developed method clearly. The obtained research results are in line with those from previous and current studies, which state that the interrelation of environmental responsiveness and age forms an inverse U and that an interest in green and energy efficient housing depends on age.

Each contemporary economic system is based on the principle of work sharing in creation and distribution of goods and services, the legal reflection of which is the institution of agency. In business, unauthorised agency, i.e. cases when an agent acts without having authority or exceeding it, is particularly often. Though the principal usually is not legally bound by actions of such an unauthorised agent, but in fact legal acts of each country provide for exceptions from this rule. One of them is the ratification doctrine, which means that the principal can ratify the agent's unauthorised actions. This article analyses, by applying the comparative method, in what cases and under what procedure the ratification rule can be applied and what legal consequences it creates. A conclusion is made that the ratification doctrine is an efficient means of implementation of interests and defence of infringed rights not only of the principal, but also of other persons involved in the agency relationship, which should not be subject to any form requirements, especially in business relationships.

In the light of social and economic development multidimensional reality and inequality, the concept of multiple discrimination plays an important role in ensuring to achieve gender equality to stimulate employment and sustainability of business. Such situations in which a person is discriminated on several grounds emerge multiple discrimination. The multiple discrimination complexity redress gender intersectional inequality towards sustainable development and remains as a key challenge. The difficulty with the multiple and intersectional discrimination lies in the lack of awareness and consistent definition of multiple discrimination, patchy legal framework of antidiscrimination law and adequate judicial response. Therefore, one of Sustainable Development Goals encourage achieving gender equality and empowering all women and girls to ensure equality and non-discrimination, women's full and effective participation and equal opportunities for leadership at all levels of decision-making in political, economic and public life. This article is deemed to provide a comprehensive analysis of the multiple, intersectional discrimination based on complex inequality and discusses case law of the Court of Justice of the European Union and European Court of Human Rights from a comparative perspective. Discuss the multiple discrimination interrelationship between the human and fundamental rights framework and the Sustainable Development Goals. A conclusion is made that recognition of the multiple, intersectional discrimination will be an efficient mean for further sustainable business development and combine all ground of discrimination especially in the case of complex inequality at the area of employment.
