The publication presents the most important regulations concerning the 2015 amendment of the system of protective measures. The main focus is analyzing the most distressing measure, i.e. the placement of the offender in a psychiatric establishment. Psychiatric internment was examined mainly from the perspective of the Polish Executive Penal Law proceedings and, to a limited extent, also in the criminal law context. The article identifies the advantages and disadvantages of the new psychiatric internment’s construction and points out the impact of that changed institution on the practice of implementing these protective measures. For this reason, the science paper presents a range of de lege lata and de lege ferenda suggestions, which may be helpful for attorneys and legal counsels in the performance of their work in the enforcement stage of criminal proceedings.

The paper discusses the issue of selected tax law institutions that constitute a form of tax credits and other tax incentives relating directly to the immovable property market in a broad sense, which have been implemented into the Polish legal system in recent years. The article includes an analysis of the legal aspects of the functioning of the relevant regulations, the statutory objectives of their introduction, as well as possible disputed issues revealed in the course of their application raised in judicial practice. The authors attempt to answer the research question whether the tax reliefs used in Poland adequately fulfil the tasks set for them by the legislator and how they influence the real estate market in Poland.

The purpose of the paper is to identify the axiological "image" of housing, perceived by students, taken as a specific group of respondents, offering an opportunity to visualise the cultural changes taking place in modern society. A CAWI survey was used with a non-random sample of 407 university students nationwide. The article is based on Gutman's means-end chain method and Schwartz's basic values theory. The respondents are as traditional as their parents and grandparents, with tradition, conformity and security dominating in the area of housing, with very low trust in other people. Respondents' strong pro-ownership attitudes predominated in the group of values that constitute self-enhancement, such as power, achievement and hedonism. Any shared space is accepted by only 11% of respondents. [ABSTRACT FROM AUTHOR]

This paper investigates residential mobility in Poland. The main focus is placed on determining the level of housing mobility in Poland, as well as finding statistically significant differences between various socio-economic groups. The research was based on microdata from the 2017 wave of the Household Finance and Consumption Survey (HFCS). The findings indicate that residential mobility in Poland was relatively low in comparison to other European Union member states, and there were statistically significant differences in housing mobility based on age, tenure status, income, wealth, level of education and the household's composition. The study concludes that improving housing affordability is crucial for enhancing housing mobility in Poland. [ABSTRACT FROM AUTHOR]

Volodymyr Kulchytsky (Włodzimierz Kulczycki, 1852-1936) was a veterinarian, zoologist, prominent mammal anatomist, professor, pro-rector and rector of the Academy of Veterinary Medicine in Lviv. From 1882 to 1934 he worked at the Lviv Academy of Veterinary Medicine, first as an assistant, then as a lecturer, and from 1906 as a professor, head of the Department of Descriptive Anatomy, Topography, Histology and Embryology (later, after changes, the Department of Comparative Anatomy). He also worked as a veterinarian at the Lviv Horse Tram Society, as a city veterinarian and as a veterinarian for controlling cattle and meat on the Lviv railroads. Kulchytsky's scientific output comprises about 60 publications (brief research papers, studies and scientific articles, discussions, reviews, etc.) on topics ranging from zoology, mammal anatomy, and parasites of oriental carpets. A completely unknown part of Kulchytsky's scientific biography was the hippiatric research conducted on the morbidity of locomotive transport animals. The statistics he compiled included, first and foremost, a list of diseases of tramway horses, taking into account pathological conditions directly related to the type of work performed. The documentation makes it possible to indicate the relationship between the work performed (norms and dimension of work), the city's topography, the construction of the tramway infrastructure, and the morbidity of streetcar horses.

The year 2022 marks 30 years since the passing of Zofia Kozarynowa--a writer, publicist, translator, Polish language instructor at the University of Turin between 1929 and 1939, Polish emigration literature nestor. The paper presents Kozarynowa's biography and her large output, as well as describes this interesting and controversial personality that stimulated her versatile activity. Additionally, it shows the family and social circle from which she originated, and the communities she lived in and worked with first in Poland, then in Italy, and ultimately in Great Britain. [ABSTRACT FROM AUTHOR]

The paper demonstrates the significance of bio-introscopy, or dermo-optical perception, to Jadwiga Stańczakowa's poetry. Searching for the connection between Stańczakowa's poems and her exercise in distinguishing colours and objects, Marta Tomczok describes the concept of dermo-optical perception, created by Lech Emfazy Stefański, Stańczakowa's teacher and co-creator of the Theatre at Tarczyńska Street, with the language of poetics, analysing a large group of poems from Stańczakowa's rich output. Thanks to juxtaposing dermo-optical perception with the concept of embodied wisdom by Juhani Pallasmaa, Stańczakowa's poetry becomes more than an individual struggle to maintain eyewitnessing in literature; it transforms into a kind of art similar to sculpture or architecture, oriented to its own processualism, as well as such multisensory artistic creation that embodies wisdom. [ABSTRACT FROM AUTHOR]

The key issue discussed in the paper is a controversial significance of Gabriela Zapolska's journalistic sketch W sprawie emancypacji ( About Emancipation), composed as a reaction to a medicine doctor Karolina Szulcówna's doctoral dissertation defended in the Sorbonne. In the text, Zapolska formulated her life credo: "Kobietą jestem--i tylko... kobietą chcę zostać do zgonu [I am a woman and I only... want to remain a woman until my death]," convincing the readers of "Kurier Warszawski" ("Warsaw Courier") to believe into invariability of biologically, religiously and culturally sanctioned principles that govern the sex-dependent roles. Glorifying males and approving their superiority over females, she places women within family circle and deprives them of the possibility of higher education as well as of any importance outside family sphere. Zapolska's sketch, to this day commented several times, is here subject of yet another interpretation equipped with new contexts. [ABSTRACT FROM AUTHOR]

The paper is an attempt at researching a description of little known Inter-war poetry devoted to Our Lady of the Gate of Dawn. Crowning of Our Lady's painting took place in 1927 as an act of grace after Poland regained independence, and this fact proved to have religious and patriotic dimension in that it favoured national identity creation. Both aspects of the event became a source of inspiration for the verses in question. Tierling-Śledź juxtaposes pieces derived from various literary registers. Apart from the works by such recognised Inter-war poets as Teodor Bujnicki or Witold Hulewicz, the authoress analyses more poetry (poetic texts) of occasional and confessional character than fine artistic lyric. Minorum gentium poets vividly demonstrate the power of literary clichés as well as national and literary community the identity of which grows from living and experiencing models (also religious ones). These poems and the modes they were made public are interesting sociological documents of the epoch. A separate part of the article is dedicated to research in poetics of the poems with special attention paid to the literary genetic pattern of the litany. [ABSTRACT FROM AUTHOR]

The paper serves to delineate the figures of early modern Protestant women included in Erazm Otwinowski's paraenetic poetic collection Sprawy abo historyje znacznych niewiast (Affairs or Histories of Notable Women, 1589), namely Anne Askew, Jane Grey, Olympia Fulvia Morata and an anonymous "duchess," presumably Vittoria Colonna or Caterina Cibo. As its purpose, the article accomplishes an identification of possible (oral or written) sources of information about the heroines and interpretation of intertextual references made by the poet. All that allows the author to depict the parenetic patterns for pious women that Otwinowski outlined, combining apology of martyrdom, learnedness, and religious exile. [ABSTRACT FROM AUTHOR]

Cyprian Norwid's Wanda stands out above other dramas devoted to the beginnings of the Polish nation. Its uniqueness consists in the fact that its fantastic history is inscribed into a Christian story since Wanda's freewill sacrifice as an religious act precedes the birth of the Polish peoples. The author of the paper introduces various interpretive orders that make up a certain two-voice structure. From the perspective of postcolonial theory, Wanda reveals a mechanism of appropriation the old pagan religion by the Catholic Church. Norwid's worldview is particularly complex, and his relation to the Catholic Church proves ambiguous. The poet sees no special value in old cultures unless they scent Christianity. In Rudaś-Grodzka's interpretation, the main role is played by mystical tradition and feminist criticism, especially Lucy Irigaray's writings (the central category being the term Mystérique that she coined). This perspective broadens our understanding of national phantasms structure. The subject of reflection is hysterical personality of the Polish nation represented by Wanda in Norwid's drama.

The aim of this paper was to give a concise review of important poultry viruses with oncogenic properties. Depending on whether the etiologic agent is known, neoplasms of poultry are divided into virus-induced neoplasms and neoplasms of unknown etiology. There are three, economically important, virus-induced neoplastic diseases of poultry: Marek’s disease (MD), caused by herpesvirus, avian leukosis/sarcoma (ALS) and reticuloendotheliosis (RE), both caused by retroviruses. Although these neoplastic diseases cause economic losses from tumor mortality and poor performance, some have also served as highly suitable models to study pathogenesis of neoplasia. Lymphoid leukosis is a disease of poultry caused by avian leukosis virus (ALV). The disease is characterized by development of B-cell lymphoma in chickens aged approximately 16 weeks and older. Standard criteria used for diagnosis include disease history, clinical signs, gross necropsy and histopathology. There is no treatment nor vaccine available, so eradication of the virus from breeding flocks is the most effective control method. [ABSTRACT FROM AUTHOR]
