The article analyses the determinants of cooperation and better communication between stakeholders in EU countries on the issue of policy pertaining to posted workers. The methodology of the current research is based on the data collected through qualitative research. The interview method has been used in order to obtain the data from the stakeholders involved in the policy for posting workers. According to the research findings, information exchange and cooperation are well-developed on a regional level. The broad diversity of information exchange practices has been found in the policy stakeholders’ network. However, all the networks are in start-up phases.

Artykuł analizuje uwarunkowania współpracy oraz lepszą komunikację między interesariuszami w krajach UE w zakresie polityki dotyczącej pracowników delegowanych. Metodologia obecnych badań opiera się na danych zebranych w badaniach jakościowych. Metoda wywiadów została wykorzystana w celu uzyskania danych od zainteresowanych stron zaangażowanych w politykę delegowania pracowników. Zgodnie z wynikami badań wymiana informacji i współpraca są dobrze rozwinięte na poziomie regionalnym. Szeroka różnorodność praktyk w zakresie wymiany informacji została odkryta w sieci zainteresowanych stron. Jednak wszystkie sieci są w fazie rozruchu.

The article discusses the issues of employee financial participation in Baltic states which differs and depends on political, legal and economic preconditions. The aim of the research is to analyse employee financial participation as an instrument for collaboration in companies and a new social cooperation model in the Baltic states. The qualitative research was conducted by telephone and e-mail in 2016. The interviews were carried out with the experts (academics, civil servants, lawyers and human resource consultants working in a relevant field) as well some trade union and company representatives. In general, the new policy for supporting employee financial participation has been renewed in Latvia and Lithuania. It started recently with the revision of the legislative framework that was initially established during the privatisation period. The revision of the Law of Companies was driven by the business interest (to have a new effective human resource management tool or to transfer employee share plans from parent companies in Western countries to subsidiaries in the Baltic states) to introduce (or revise, in the case of Lithuania) new employee share ownership (ESO) plans. The research has also proven that there are common similarities in the use of employee financial participation plans despite the existing differences which are based on national features, such as tax and legal regimes, historical development patterns, or economic and structural factors.

The aim of this article is to assess critically institutional and policy arrangements for evaluation within Lithuanian public administration in order to manage the support of the European Structural Funds and the use of evaluation requirements of EU structural funds as a limited cased study. What has been changed in the administrative arrangements of EU Structural funds support during the two programming periods 2004-2006 and 2007-2013? A key research question is to assess administrative arrangements for evaluation within Lithuanian public administration in order to manage the support of the European Structural Funds and use of evaluation requirements of the EU structural funds as a limited case study to map how these arrangements are or are not developed, and isolating the key explanatory factors. Methodologically, we used semi-structured qualitative interviews and quantitative online surveys of officials, academics and evaluators. The research results show that isomorphism and donor-oriented evaluation dominates in the evaluation system of the EU Structural and Cohesion funds. Lithuania transfers the elements necessary for support evaluation to the public administration systems. From the intervention approach, supporting many programmes and projects, there is a change to the approach based on long-term planning, programming and consulting with the stakeholders. The current paper covers three significant topics (a) the evaluation of the EU Structural support to Lithuania; (b) the institutional and policy arrangements for evaluation within Lithuanian national government; (c) evaluation capacity for public policy evaluation within Lithuania. The research itself contributes to the spread of evaluation theory and practice in the new EU member states. State officials will be able to learn and compare the implementation of evaluation in other member states, what aims were reached, what the scope and significance of evaluation is dependent on evaluation coordination and system centralization-decentralization and what the influence of cultural aspects on evaluation implementation is. The evaluation community could learn about the differences of evaluation systems, possibilities and restrictions, the applied evaluation methods and means of evaluation quality management in order to work in a certain market.

Herbicides, fungicides and bactericides containing heavy metals used in agriculture make it possible to find these toxic metals in beer. The aim of this work was to monitor the distribution of some toxic heavy metals as Cd, Pb, Ni, Cr, As and Se during beer production. The experiments were observed in pilot plant scale conditions. Except arsenic only a very low fraction of other metals passed into beer. Grain absorbed the majority of the metals (primarily Hg and Pb, the least in the case of As). The yeasts absorbed smaller part of the heavy metals, mainly Ni, As and Se. From the above-mentioned heavy metals only the arsenic was the metal from which the substantial part passed into beer (about two-thirds of added amount). Even after such a large spiking of the brewing water by the concentrations of 0.1÷0.5 mg/dm3 of individual heavy metals, the content of heavy metals, except for arsenic, in beer remained below the legislative limits.

Metale ciężkie zawarte w środkach chwastobójczych, grzybobójczych i bakteriobójczych stosowanych w rolnictwie są obecne także w piwie. Celem pracy było oznaczenie stężenia niektórych toksycznych metali ciężkich, jak: Cd, Pb, Ni, Cr, As i Se, powstających podczas produkcji piwa. Badania prowadzono z wykorzystaniem instalacji pilotażowej. Ogólnie stwierdzono małe wartości stężenia metali ciężkich w piwie, wyjątek stanowił arsen. Ziarno akumuluje większość metali (przede wszystkim Hg, Pb i As), natomiast drożdże akumulują mniejsze stężenia metali ciężkich, głównie Ni, As i Se. Z oznaczanych metali ciężkich tylko znaczna część arsenu przeszła do piwa. Stężenie metali ciężkich w piwie, z wyjątkiem arsenu, było mniejsze od dopuszczalnego stężenia wyznaczonego przez normy prawne.

Na podstawie uzyskanych wyników z badań określono optymalne receptury zaczynów uszczelniających, które mogą być zastosowane zarówno w technologiach wiertniczych (cementowanie kolumn rur, likwidacja odwiertów, wykonywanie korków) jak i w pracach geoinżynieryjnych związanych z uszczelnieniem i wzmocnieniem ośrodka gruntowego lub masywu skalnego. Badania laboratoryjne przeprowadzono na zaczynach sporządzonych na osnowie cementu portlandzkiego CEM I 32,5 R o współczynnikach wodno-mieszaninowych 0,4; 0,5; 0,6 i 0,7, zaś koncentracja popiołu fluidalnego w zaczynach wynosiła 5, 7 i 10%.

The aim of the robot path planning is searching for a path from a start to a goal position without collisions with known obstacles minimizing length, difficulty and risk of the path. A two-dimensional grid with known static obstacles models the robot environment. When planning a path, the most similar cases (already used paths or their parts) are searched for to be subsequently adapted to the new problem. A genetic algorithm is used to find the missing parts of the constructed paths or new paths if similar cases are not found or adapted solutions are not good enough.

Celem planowania trajektorii ruchu robota jest poszukiwanie trajektorii od punktu startowego do pozycji docelowej bez kolizji ze znanymi przeszkodami, przy minimalizowaniu jej długości, trudności oraz ryzykowności. Otoczenie robota modeluje dwuwymiarowa siatka ze znanymi statycznymi przeszkodami. Podczas planowania trajektorii poszukuje się najbardziej zbliżonych przypadków (trajektorii wykorzystanych już wcześniej bądź też ich części), aby następnie zaadaptować je do nowego problemu. Algorytm genetyczny wykorzystywany jest do odnalezienia brakujących części wyznaczanych trajektorii, bądź nowych trajektorii w przypadku niemożliwości odnalezienia podobnych przypadków lub gdy zaadaptowane rozwiązania nie są wystarczająco dobre.
