Rufinus, the author of erotic epigrams appearing in book 5 of the Palatine Anthology, remains a mysterious personage since scholars have divergent opinions on the period in which he lived. The article relates those discussions and analyses the contents and style of the poems, ten of which are translated here into Polish.

Dynamic changes and the increasing diversity of migrant societies support small-scale enclave businesses in Poland. Female migrants from Belarus and Ukraine appear to have found their niche in the beauty and cosmetology sector. Nevertheless, their entrepreneurship goes beyond the enclave market. Specialists provide services to migrant communities and simultaneously target Polish clients to ensure the success of their ventures. This article presents the results of qualitative research based on 13 in-depth interviews with Ukrainian and Belarusian beauty specialists. I focus on these businesswomen’s narratives about their entrepreneurial trajectories. My aim is to explore how they use and extend their social relationships in order to acquire entrepreneurial agency. Entrepreneurship can be understood as a socially embedded practice. I apply an intersectionality approach to investigate the complexity of socially constructed identities and the dimensions of individual entrepreneurial agency. Incorporating a mixed embeddedness approach, I examine the impact of structural factors on entrepreneurial activity and the importance of social networks for women’s self-realisation as independent beauty specialists.

The knowledge of performance characteristics of turbine stage groups is still insufficient, particularly in the general case of changes of operating conditions. This situation is caused mainly by the scarcity of experimental data available. In such case, the opportunity to obtain the required data, using mathematical modelling and numerical simulation of the operation of stage groups under off-design conditions instead of physical experiment, seems to be attractive. The application of this idea for impulse type turbine stage groups was presented in [I], [2]. Here we discuss similar results but obtained for reaction type turbine stage groups, that is: - mathematical model for computer simulation of operation of reaction type turbine stage group, under variable regime (based on Ainley's and Mathieson's method with some improvements); - simulation results for a number of stage groups designed according to former BBC and traditional concepts; - more general properties of these groups (in relation to flow capacity and efficiency) obtained from the analysis of simulation data; - comparison of observed properties of impulse and reaction typy turbine stage groups.

The question of the human person is very important for moral theology because of the possibility of responsible human action. Nevertheless, the old utilitarianism that already comes from the empiricist position of Hume reduces the calculation of costs and benefits to an evaluation of the pleasant/unpleasant of the individual subject. The new utilitarianism takes its inspiration from Bentham and Mill and can be summarized in a threefold injunction: maximizing pleasure, minimizing pain, and expanding the sphere of personal freedom for the greatest number of persons. One of the popular promoters of preference utilitarianism in modern times is the Australian ethicist Peter Singer, whose controversial views attracted much attention not only from the scientific community in the late 1970s. In this paper we will try to show a critique of this position in several figures of philosophical and theological ethics as well as a defence of the importance of the notion of the human person and human dignity for the integral protection of human life from conception to natural death and of anthropocentrism as such in respect for all creation and all of nature.
