The advancing degradation of the ecosystem and the occurring climate changes demand decisive action to be taken by citizens, aimed at levelling the results of the lack of balance between the natural environment and business operations. The growing importance of ecology is reflected on the international financial market in the form of green bonds. This article is devoted to green bonds which are a specific group of securities, namely ecological debt instruments. Despite the green debt being one of the most recent segments of the capital market, its very dynamic expansion can be observed year by year. The article is aimed at identifying the conditions for the development of the global environmental bonds market, specifically the factors stimulating and inhibiting the process. The article is a review in character and the following research methods were used in order to achieve the desired objective: analysis of subject literature and data analysis from the green bonds market, a case study, a descriptive and an inductive method.

Migrants’ property ownership in their countries of origin is often understood through the prism of return: both intended and actual return mobilities. Applying a transnational optic, this article unpacks the relationships between migrants’ property ownership ‘back home’ and their reflections on future moves and stays, not limited to possible return. We draw on 80 semi-structured interviews conducted in 2020 with Polish and Romanian migrants living in Barcelona and Oslo. They left their homeland, sometimes following domestic migration or international migration to other countries, before arriving in Spain and Norway. Based on these case studies of East–West migration within Europe, we contribute to work recognising the ongoing complex and diversified nature of mobilities in Europe. First, we detail what migrants’ property ownership looks like in practice – forms of ownership, types of property, location. Second, we focus on how owning property in Poland or Romania intersects with migrants’ considerations about moving or staying in the future, beyond return. Considerations about future (im)mobility shed light on transnational relationships, as these evolve over time and across space. Furthermore, we find that transnational property ownership in their countries of origin reveals much about migrants’ relations with people and places ‘back home’ and reflects the known non-linearity of migration stories. Overall, however, transnational property ownership is a poor predictor of both return plans and intentions.

Phosphogypsum (PG) – a waste material generated in enormous amounts, accumulates a wide range of pollutants and thus represents a major environmental problem. Among the proposed potential strategies for PG management, none has been implemented on a large scale up to date. At the same time, the rapid depletion of phosphorite resources, used to manufacture most commercial phosphorus (P) fertilizers, poses unprecedented challenges for future agriculture and environmental protection. The aim of this study was to assess the possibility of using PG as a source of P for fertilizing plants. The effect of PG fertilization on the dry mass accumulation, P and sulphur (S) contents in soil and in the above-ground parts of plants, as well as on the level of heavy metal contaminations, were studied in the experimental model consisted of 12 genotypes of three lupine species – Lupinus angustifolius, Lupinus albus and Lupinus luteus. The PG application increased the content of both the available and active P in the soil. The increased P bioavailability resulted in an elevated uptake and intracellular content of this nutrient in the studied plant species in a dose- and variety-dependent manner. The heavy metals present in the waste did not affect their accumulation in the plants. The results indicate the possibility of using P forms present in PG as an alternative source of this component in plant nutrition, at the same time allowing elimination of the waste deposited on huge areas, which will certainly contribute to improving the quality of the environment.

The aim of the article is an attempt to trace the fate of several appellatives grouped in the lexical field around the hyperonym świnia ʽpig, swine’ (wieprz ʽhog’, knur/kiernoz ʽboar’ and prosię ʽpiglet’) as the motivation of many names in Polish onymy, mainly in anthroponymy and toponymy. My research has been conducted along the lines of historical anthropology. Proper names in this approach play an important role in the reconstruction of the past. The field of interest of this article includes mainly names belonging to the old onymic layer. Proper names arise from the lexicon of a given language, which is why my analysis is based on lexical and semantic methodology. My point of departure is the meaning (often reconstructed) of appellative lexical units, including their semantic modifications in the proprial layer. I interpret proper names on the basis of findings regarding their origin and motivation. The first names motivated by the lexeme świnia were associated with the economic organization of the Piast state. In the article I present the history of their creation. I go on to discuss the other lexemes which became the basis of many names belonging to different naming categories. The presence of etymons of interest to us in so many proper names during the Middle Ages allows us to draw the conclusion that pigs played an extremely important role in the lives of our ancestors.

Analysis of lead and cadmium concentrations in the air comparing concentration values difference between heating and summer seasons was carried out in the paper. Relevant procedure was adopted to find out if the concentration values in these two seasons differed in kind. The concentration seasonal difference was not found in case of cadmium but it was found for lead. It was proved in further part of the paper that the analysed mean 24-hour Pb concentrations for heating season could be presented as a sum of the mean annual background concentration and the concentration values resulted from Pb emission from sources active only in the heating season. In the area where the measurements were carried out residential furnaces were this kind of sources. The cumulative distribution function of the mean 24-hour lead concentration resulted from Pb emissions in the heating season was determined using two-layer neural network. It was found according to this approach that Pb concentration as the result of Pb emissions from residential furnaces, for 145 days, i.e. 80% of the heating season period, were at least two-fold lower than the lead concentration values as the result of Pb emission from the all year active sources. Only for 14 days emission sources active in the heating season produced Pb concentrations higher than Pb mean annual background concentration.

The ethics of ‘theistic absolute morality’ (TAM), as any other ethical theory, must offer a definition of good, describe the connection between good and duty, and provide an effective guidance to human conduct. In the ethics of TAM we find, in my rendering of its claims, an irremediably unsuccessful definition of good, permanently loose connection between moral value and moral duty, and irreparably limited practical efficacy. It is not surprising that it has to be so, as it is a common condition of all ethical systems. The TAM ethics suffers, however, additionally from a unique conceptual trouble, but that is a story I have told elsewhere.

The article deals with the problem of historical writing. Up to our time methodologists used to believe that authors of historical works were exclusively historians themselves. The contemporary philosophy and literary theory rejects the idea of such an importance of the author. Other factors like paradigm, discourse or culture are admitted also into creation of historical texts.
