    Transport is a considerable source of pollution in cities. The social impacts of transport activities result from emissions of pollutants, greenhouse gases, and noise, as well as traffic accidents. Not every urban investment that reduces such ‘external’ effects of transport will be found acceptable by the public. In order to assess and communicate the social impacts of investments, it is necessary to calculate external costs appropriately. This article discusses issues with estimating the social costs and benefits of transport-related investments in cities. The article also provides a classification of social benefits from urban transport investments and proposes a general methodology for estimating such benefits. Due to the versatility of urban investments, there can be no single, universal method. The article proposes methods for analysing social costs and benefits on the basis of two sample urban investments.

    Video surveillance on both marine and inland waters still only plays a mainly auxiliary role in vessel traffic observation and management. The newest technical achievements in visual systems allow camera images to be used in more sophisticated tasks, such as automatic vessel recognition and identification in observed areas. With the use of deep learning algorithms and other artificial intelligence methods, such as rough sets and fuzzy sets, new functions can be designed and implemented in monitoring systems. In this paper the challenges that were encountered and the technology that has been developed in managing video streams are presented as well as the images needed for tests and proper operation of the designed Ship Recognition and Identification System (SHREC). The current technologies, typical setups and capabilities of cameras, with regard to existing on-water video monitoring systems, are also presented. The aspects of collecting the test data in the Szczecin Water Junction area are also described. The main part of the article focuses on presenting the video data pre-processing, storing and managing procedures that have been developed for the purposes of the SHREC system.

    The article presents regression formulas for calculating the friction resistance RF and the total resistance RT of ship models in the 2.0–10.0 m range. The method for calculating the total resistance is novel and applies to the design models of an unmanned surface vessel (USV) for experimental testing of autonomous control. For both regression models (RF and RT), statistical and substantive tests were performed (the results of the calculations were compared with the experimental measurements). In both cases, convincing results were obtained, which have confirmed the possibility of their use at the preliminary design stage of unmanned ship models.

    Environmental protection has increasingly adopted economic dimensions, and the environment is treated as a “capital” that can be used for economic and social development. This capital must be preserved for future generations, which is why increasing attention has been paid to taking pro-ecological actions to protect the environment. In order to improve the quality of the environment, it is necessary to make various types of investments in it. The Sustainable Development Initiative assumes that the economic growth of countries should be implemented in a manner consistent with the natural conditions of nature. The aim of this study was to identify and present the current possibilities of financing sustainability in Poland after joining the European Union, taking into account the risk of undertaking such an investment.

    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.
  • Milewski, Dariusz (Scientific Journals Maritime University of Szczecin, Zeszyty Naukowe Akademia Morska w Szczecinie, )
    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.
