The paper aims to determine the criteria and sub-criteria for evaluating the contractor’s performance and finalize a master list of the criteria and sub-criteria to be used for evaluating contractor’s performance with their respective weights. The method is incorporated in the framework proposed for the evaluation of the contractor’s performance during the execution phase. An exploratory study has been opted, using a structured, close-ended multiple-choice questionnaire survey approach. The questionnaire survey was conducted in two phases, i.e. validation survey, and reliability survey. Fifteen experts responded to the validation survey, and thirty experts to the reliability survey. The experts were from Government and public sectors in India, working at various senior levels. The weights of criteria and sub-criteria were calculated from data collected in the survey, relative importance was calculated through the relative importance index and criteria were ranked. The paper provides criteria and sub-criteria which were finalized through a questionnaire survey by classification of criteria identified in literature and tender review. The respective weights were finalized, which can be measured while evaluating contractors’ performance. The weights assigned to criteria through the survey are; health and safety is 13.19%, followed by finance 11.93%, time 11.93%, quality 13.38%, client satisfaction 12.42%, environmental safety 12.32%, productivity 12.51% and regulation 12.32%. The paper provides the criteria and sub-criteria with their weights needed for evaluating the performance of contractors during the project execution phase. This research can lead to a culture of continuous measurement of performance for the satisfactory completion of projects.

The article analyzes the structure of energy resources, as a result of which the reasons for their irrational use in the Ukrainian economy are revealed. It has been established that during 2014–2018 there was a decrease in demand for traditional types of fuel and energy resources (FER), except for coal. The components of the process of supply and consumption of fuel and energy resources have been formed and detailed, and an integrated approach to their rational use has been developed, which will reduce the loss of energy resources and increase their efficiency. The author’s approach is used in the form of visualized schemes for organizing the process of the rational use of energy resources, which will contribute to the implementation of an effective energy saving policy of the state, ensuring the competitive advantages of domestic enterprises, increasing their competitiveness, improving the economic and energy security of Ukraine. The expediency of constructing deterministic economic models for providing the Ukrainian economy according to different (adaptive and multiplicative) convolutions was substantiated and proved, on the basis of which a forecast and assessment of the energy independence of the Ukrainian economy until 2035, taking into account fuel and energy resources, was proposed. Based on the calculations, it was established that the state of energy independence of Ukraine is insufficient.

W artykule dokonano analizy struktury zasobów energetycznych, w której wyniku ujawniono przyczyny ich nieracjonalnego wykorzystania w ukraińskiej gospodarce. Ustalono, że w latach 2014–2018 nastąpił spadek zapotrzebowania na tradycyjne rodzaje paliw i surowców energetycznych, z wyjątkiem węgla. Elementy składowe procesu zaopatrzenia i zużycia paliw i surowców energetycznych zostały określone w sposób szczegółowy oraz wypracowano zintegrowane podejście do ich racjonalnego wykorzystania, które ograniczy utratę zasobów energetycznych i zwiększy ich efektywność. Autorskie podejście wykorzystywane jest w postaci poglądowych schematów organizacji procesu racjonalnego wykorzystania surowców energetycznych, co przyczyni się do realizacji skutecznej polityki oszczędzania energii w kraju, zapewniając przewagę konkurencyjną rodzimym przedsiębiorstwom poprzez zwiększenie ich atrakcyjności, poprawę bezpieczeństwa gospodarczego i energetycznego Ukrainy. Uzasadniono i udowodniono celowość konstruowania deterministycznych modeli ekonomicznych ukraińskiej gospodarki według różnych (adaptacyjnych i multiplikatywnych) splotów funkcji, na podstawie których przedstawiono prognozę i ocenę niezależności energetycznej ukraińskiej gospodarki do 2035 roku, z uwzględnieniem paliw i zasobów energetycznych. Na podstawie obliczeń ustalono, że stan niezależności energetycznej Ukrainy jest niewystarczający.

International road transport is a specific service within the frame of services provided in the European Union. It is because the conditions of being active on the market are influenced by the states where businessmen operate, but services can be provided throughout the whole year in other member states of the European Union. The aim of the contribution is to highlight the existing problems in international road freight transport sector. These problems persist despite the fact that market access was exempted from the national law of individual member states and regulated directly by EU regulations. Despite the unification of market access, tax and social harmonization is not ensured in international road freight transport. An unequal tax burden on carriers and different requirements of wage regulations create a discriminatory environment among entrepreneurs. The contribution identifies the factors that deform the equal operating conditions in single market. The aim of the contribution is also to provide the readers with the answers to the questions: Is it possible under current EU conditions to harmonize tax and social conditions? What impact would this harmonization have on business environment?

The former socialist/communist rule kept Romania almost isolated from the Western World during about half a century (1945-1989). All about 7000 Romanian former state-owned companies (which were operational at the end of 1989) were obliged, by Law, starting the years ‘60, to organize their own so-called „CTC (Technical Quality Control) Department”, in order to only inspect the quality of their products. In 1992, two years only after the fall of Ceausescu’s dictatorship, in Romania were published both the first Romanian edition of famous ISO 9001 standard (in 1987, when ISO published its first international issue, the former Romanian regime did not allow the translating of it in Romanian!) and the first Consumer Protection Act in Romania’s history. This paper introduces - from both historical and professional insider’s perspective - the most important facts, challenges, issues and outcomes of these very important events, happened over two decades ago.

Poprzednie komunistyczne/socjalistyczne zasady trzymały Rumunię w izolacji od świata zachodniego, przez ponad pół wieku (1945-1989). Około 700 rumuńskich przedsiębiorstw państwowych (które działały pod koniec 1989 roku), były zobowiązane, przez prawo, od lat 60-tych do organizacji własnych oddziałów zwanych Technicznymi Oddziałami Jakości, w celu przeprowadzania kontroli jakości swoich produktów. W roku 1992, dwa lata po upadku reżimu Ceausescu, w Rumunii opublikowana została pierwsza norma ISO 9001 (w 1987 roku, kiedy ISO opublikowała swoją pierwszą międzynarodową normę, rząd w Rumunii nie wyraził zgody na jej tłumaczenie) a także Consumer Protection Act - pierwszy w historii Rumunii. Niniejszy artykuł przedstawia - zarówno z perspektywy historycznej jak i zawodowej - najważniejsze fakty, wyzwania, problemy i rezultaty tych ważnych wydarzeń, które miały miejsce ponad dwie dekady temu.

At present, geographic work, and landscape research in particular, is carried out basing on three coexistent paradigms. The first is the classical paradigm arising from the neo-positivist orientation with scientistic approach. Representatives of this approach follow the rule of objectivity and independence of perception of the object (landscape) in relation to the observer (subject). The principal determinant of this approach is methodological unity and rationalism based on the rules of quantitative, mathematical-statistical description. Foremost among others, this trend is representted by followers of the eastern school of landscape research, named “landshaftovedeniye”. Among the classical followers of this approach, there were L.. S. Berg, N. A. Solontsev, A. G. Isachenko, F. N. Milkov, D. L. Armand, V. J. Preobrazhensky, A. I. Perelman, N. A. Gvozdetsky. The second is the system paradigm, which develops as a modification rather than opposition to the first approach. In this aspect, studies of systems (geosystems) have become a new cognitive criterion. Its principal assumption is the holistic concept of nature. Studies of the landscape as a geosystem present the structuraldynamic and functional aspects. This trend is widely noticeable in papers by authors of landscape syntheses created within the scope of interdisciplinary landscape ecology, which is very popular currently (papers by A. Richling, M. Pietrzak, K. Ostaszewska, J. Solon, Forman and Godron, W.B. Soczawa, among other authors). The third is the humanist paradigm, which develops along with the system paradigm. It points out the role of man in the process of landscape shaping and its cultural conditions in a particular environmental context, thus referring to the idea of unity of nature and culture. It is based on papers by leading possibilists, including P. Vidal de la Blache (1922), and the so-called landscape approach, represented in Polish geography by S. Nowakowski, M. Dobrowolska, F. Bujak, or J. and F. Plit, among others. Coexistence of those paradigms results in discrepancies in understanding and interpretation of the landscape. The presentation will show the current stage of research and prospected further studies of cultural landscape resulting from the possible combination of the classicist approach of humanist geography and use of new research methods and sources.
