    This study presents an assessment of the equivalence of measurements of particulate matter PM10 concentrations using a low-cost electronic device as compared to the reference method. Data for the study were collected in accordance with the guidelines for research equivalence of the two devices operating in parallel. On this basis, a model correcting raw measurement results was developed. The best results were obtained for the model having the form of a second degree polynomial and taking into account air temperature. Corrected measurement results were used in the equivalence testing procedure. As a result, confirmation of equivalence was obtained for the vast majority of data sets generated from original measurements. This confirms the usefulness of the device as a tool for monitoring air quality.

    The RESPECT Index (RI) is the first index of socially responsible companies in Central and Eastern Europe and has been operating in Poland since 2009. In accordance with its philosophy, the RI includes listed companies showing the highest standards of quality in corporate governance and information governance regarding their impacts on the natural environment, society, and employees. Do the non-financial reports of these companies confirm that they meet these standards? This article attempts to answer that question, which aim can also be described as the qualitative assessment of the non-financial reports of the largest listed Polish companies in the RESPECT Index, with particular emphasis on analyzing the structure and content of the companies’ non-financial information disclosures. In order to achieve this goal, the paper first defines non-financial information and its usefulness to stakeholders in modern enterprises. Secondly, the paper discusses problematic aspects of non-financial reporting. And the third part of the paper is a qualitative analysis of the non-financial reports of 12 out of the 31 Polish companies in the RESPECT Index. Finally conclusions are that the research conducted confirmed a wide variety of these companies’ disclosures, and on the other hand, exposed some deficiencies in published reports, including their narrative character, limited comparability across time and space, and lack of external verification. All this shows that it is not enough to be a socially responsible company; you must also report this activity skillfully. This study used the following research methods: literature review, analysis of legal regulations, desk research, and inductive and synthetic reasoning strategies, in order to formulate conclusions.

    Development and innovation in the e-commerce sector over the last decade have been extremely dynamic. Market development has increasingly been driven by the changing behaviour of consumers shopping online and the growing number of e-stores. This article identifies the pro-innovation areas and actions which are creating special value propositions for e-buyers in Poland and assesses their impact on shopping decisions for each generation (X, Y, and baby boomers) by assessing the impacts of differences in the preferences of the generations regarding e-commerce. Each generation differs significantly from the others in terms of work, education, security, success in professional and personal life, and in terms of consumption. The characteristics of the individual generations and the levels of their digital competencies impact significantly on the ways in which a given generation makes purchases and what they expect during the purchasing process. In order to establish the key determinants of online purchasing decisions and attitudes towards innovation in e-commerce, an online survey was conducted. The sample included three generations of Polish internet users: 260 people at ages between 25 and 37 (generation Y); 200 people at ages between 38 and 50 (generation X) and 100 people at ages between 51 and 70 (the baby boomers’ generation). The structure of the article includes presentations of the problem against the background of relevant literature, the theoretical assumptions of the research, and its findings and conclusions.

    This article presents topics related to the main stakeholders of enterprises in the 21st century – employees operating in a market dominated by globalization and technological progress. To a large extent, they determine the competitive position of their organizations. To this end, the author describes the expectations of Polish employees as key stakeholders of the organization in which they are employed. Moreover, the author defines and describes the conditions that must be met to optimize the use of their potential. Good relations with this group of stakeholders is the basis for creating business strategies in the 21st century. The author also presents a description of his own research, which concerns the analysis of actions taken by companies aimed at creating optimal working conditions for their employees; this is also the main goal of this article. The analysis of source materials and research results indicated that employees played a large role in organizations and the need to implement dedicated tools and management methods. It should be obvious that the new economic realities force companies to invest in intangible resources, as it is thanks to them that it is possible to achieve market success. The main feature of companies that seek to achieve success is social sensitivity, which is manifested by a series of actions aimed at meeting the expectations of employees.

    This paper explores the role of regional policy in strengthening the EU’s research and innovation policy paradigm, with a particular focus on smart specializations. These specializations play a major role in stimulating R&I at the regional level in less-developed regions of the EU. Smart specialization is the EU’s new concept for the regions; it assumes improvement in both innovation and competitiveness, based on endogenic potential; in particular, in already existing branches of the economy. Smart specializations should, by definition, concentrate economic resources on chosen priorities; one of these priorities is the growth of the blue economy. Smart specializations need to be clearly defined, only then can they contribute to economic growth when combined with proper management of public financial means. The objective of this paper is to introduce and characterize the assumptions for smart specializations and to assess the progress of their implementation and the necessary conditions required in Polish regions; particularly when referring to sectors of the blue economy.

    This paper presents trade between China and Europe along the historical Silk Road, based on the materials from the Warsaw press published in the second half of the 19th century. The 19th century was a period of intense military actions led by the European empires in the Far East. The defeat of the Qing Dynasty during the Opium Wars marked the so-called cutting of the “Chinese cake” and the gradual fall of the empire. The events of this period caused an increased interest in the subject of the Middle Kingdom among Europeans and also in the Polish press.

    The aim of this paper is to assess the utilization of selected transportation modes in services facilitating Polish foreign trade between 2010 and 2017. Poland’s foreign trade in commodities is characterized generally herein. The contribution of individual transport modes (i.e. road, rail, inland waterways, sea, or air) to facilitating Polish exports and imports is analyzed in terms of quantity and value. As research material, data from the Customs Administration Analytical Centre are used. Simple statistical and graphic methods (e.g., structural and dynamics indicators) are applied. Polish foreign trade in commodities grew between 2010 and 2017. At the same time, the shares of individual transport modes in facilitating exports and imports shifted, with transport by road remaining the largest contributor. Quantitatively, the share of road transport increased, in both exports and imports; however, a reverse trend was observed for its value.

    This paper discusses logistics models of e-commerce implemented by Polish clothing companies. The author has conducted research on Polish clothing companies and logistics operators serving e-commerce branches, and here presents and compares these models. There are various logistics models of e-commerce, which differ from each other in organisation of deliveries, level of outsourcing, location for keeping stocks, level of logistics in customer service, and organisation of returns (goods returned by customers). The impact of the different e-commerce models on ecological, economic, and social priorities is then discussed.

    The problem presented in this paper concerns the impact of e-commerce on transport costs, including external transport costs, compared with traditional shopping. E-commerce is a phenomenon of the modern economy that can significantly impact both the efficiency of the distribution of goods and on external transport costs. Although such a distribution system can increase the costs of freight transport to final consumers, it can also reduce traffic in cities and thus total external transport costs. In order to asses this impact, the author developed a simulation model and used it to conduct analyses. The analyses were based on available statistical data, data from the literature, and from the transportation market in Poland.

    The exercise of the economic and social functions of maritime tourism has undergone significant changes in recent years. A case in point is the development of the maritime cruise fleet, in both quantitative and qualitative terms, across various regions. This is a result of, among other things, the changing needs of international tourists in particular regions. The worldwide expansion of globalization has also marked a turnaround in preferences, with customers now willing to visit regions formerly unattractive or rarely considered by tourists. These changes are also visible in the variety of transport modalities available to passengers for both domestic and international voyages. To a large extent, these changes stem from technological developments. New possibilities for quick and efficient passenger transport have contributed to transforming maritime tourism in many countries. This, in turn, has led to increasing volumes of tourist traffic, generating economic growth for such nations. This article discusses contemporary trends in the world’s cruise ship fleets in the context of the technical parameters of global cruise shipping. The authors have attempted to determine the basic quantitative parameters and metrics expected for characterizing the global cruise ship fleet. To accomplish this, the method of linear regression has been used, with the input data being the sizes of cruise ship fleets and some other characteristic parameters, during particular time periods, carrying capacities, registered tonnages, numbers of passenger cabins, main and auxiliary engine powers, and levels of fuel consumption. The econometric model of linear regression has allowed calculating the projected values for the nearest future.

    The issue of the impact of seaports on their direct vicinity has been repeatedly addressed in the academic literature. The developed merits of their impact is mainly related to employment in the port/port cluster, the seaport’s share of the municipality’s labour market, and the added value produced by the port/port cluster or the volume and structure of uncompensated flows into the municipality’s budget on account of the port’s operations. This article is aimed at providing an answer to the question of how to evaluate the impact of a new investment project in a seaport on its direct vicinity in a situation of low unemployment in the port’s municipality and the dominating tourism function in its economy. The research methodology was based on a single case study of the city of Świnoujście and the seaport in Świnoujście; the dominating economic function of this municipality is tourism. Moreover, it is the location of one of the four seaports with primary significance for the national economy. The development plans for the Szczecin & Świnoujście Seaports Authority include the construction of a deepwater container hub terminal. The investment will have an impact on the local social environment. The results of the conducted research studies are presented in the article both in a traditional approach enumerating the benefits of such an investment project for the local environment, as well as proposing a new approach to the evaluation of its benefits (inter alia, providing employment opportunities for people who so far have been forced to look for jobs outside the municipality and the long-term unemployed, preventing young and educated people from moving out of the municipality, attracting new inhabitants, improving the employment-to-population ratio, and stopping the city’s population ageing).

    Due to the development of alternative propulsion systems, there is a need for LNG tanker turbine propulsion plants to regain their competitiveness. Previous research revealed effective methods to increase the thermal efficiency of the steam cycle based on quality assessment, and it was proposed that the latent heat of the main turbine exhaust steam could be recovered. Research was carried out for the steam cycle using regenerative heat exchangers fed by steam jet injectors. In this paper, an algorithm to determine the operating parameters of steam jet injectors, and the calculation results for different drive steam parameters are presented. The obtained results will be used as input parameters for further heat balance calculations of the proposed regenerative steam cycles.

    Today, every industry is striving for the highest efficiency and best economic results possible, with the greatest possible competitiveness. But in maritime affairs, human safety and environmental protection are the foundations of sustainability. To achieve this, marine systems must be reliable, high quality and easy to maintain. Because of this, reliability has become an important factor in safety, which remains relevant throughout the lifetimes of ship systems, including fire alarm systems. In this paper we address a number of issues connected with the reliability – and ‘availability’ of these systems. Firstly, ship fire alarm systems consist of various components whose individual reliability affect the system’s overall reliability. Discussions of reliability in ship fire alarm systems normally focus on the length of a system’s useful life or performance during design-based fire events. In addition to the reliability of systems, their availability for use is also crucial given the possibility that the system may need to operate at any point in time.

    This article presents an analysis of vertical shear forces and bending moments during nodule loading in the case of a standard bulk carrier around the Clarion–Clipperton Zone. An operational efficiency index was applied to an assessment of internal forces during loading which took into account wave heights and periods around this zone. The aim of this research was to investigate whether waves could have a negative effect on loading efficiency and to estimate the nodule mass that can safely be loaded onto a standard bulk carrier taking these waves into account. Moreover, a calculation was made to discover the acceptable vertical shear force percentage limit, while also taking into account wave activity during loading.

    The paper presents the results of laboratory simulation tests of a suspension system for a car seat. The first part of the paper contains a description of the experiment, paying particular attention to the conditions in which the tests were conducted and the properties of the electrically controlled damper, which was mounted in the tested car seat’s suspension. Graphs of the damper’s operation were determined for different values of current intensity and the signal controlling the damper’s damping ratio and then the damping characteristics were determined on this basis. Simulated tests of the car seat’s suspension were carried out on a car component test station. During the tests, the values measured were the acceleration recorded at selected points on the dummy, which was placed on a seat equipped with suspension using a magnetorheological (MR) damper during the experiment. The second part of the paper presents an analysis of the results of the experimental tests with particular emphasis on the influence of the current that controls the operation of the damper on the values of the RMS index of the acceleration at selected points of the dummy.
