“Świdermajer”, the Architecture of Historic Wooden Summer Villas in the Polish Landscape: A Study of Distinctive Features
No full textThe article covers the results of the study of a historical wooden holiday architectural ensemble called Świdermajer, located on the outskirts of Warsaw in Poland. The fashion for traveling and resting within natural surroundings emerged in the 19th century, contributing to the popularization of a new model of spending free time. It had an impact on the development of a new type of architecture, including the “Swiss style”, today representing an extremely picturesque European architectural heritage integrated into the landscape. The area of Otwock is one of a very few of such places in Poland, where the entire complexes of suburban wooden holiday buildings from the late 19th and early 20th century have survived. This paper aims to show an overview of a development of the local wooden building trend on the “Otwock Line” within its historical and social background. The main goal of the study focuses on identifying the characteristic features of the architectural wooden local style. As a final outcome of the study, the article presents the method applied for the recording and assessment of historic wooden summer villas. The conducted study confirmed the distinctiveness of the phenomenon represented by cultural values and, at the same time, its strong links with the Alpine style of architecture
Goodness-Of-Fit Tests for Doubly Truncated Data
No full textPurpose – The paper regards the goodness-of-fit (GOF) tests for doubly truncated continuous data with known truncation points. The first goal of the paper is to derive computing formulas of several test statistics for doubly truncated data, when the number of truncated data is unknown. The second goal is to develop statistical inference procedure based on the derived formulas, which includes information regarding the number of truncated data, when it is available. Research method – The formulas and the inference procedure are developed with the use of the methods proposed by Chernobai, Rachev and Fabozzi [2015], who already
developed GOF tests for the left truncated data, when the number of truncated data is unknown. Results – Several tests are developed in case of double truncation. Depending on the chosen truncation points, the tests for left, right or doubly truncated samples might be obtained. When no truncation occurs, the tests are reduced to the complete sample tests. The quality of the tests is assessed on the basis of the FTSE100 return distributions. Originality / value / implications / recommendations – To the best knowledge of the author, computing formulas of the GOF test statistics for doubly truncated distributions with known truncation points, when the number of truncated data is unknown, have not been presented in the literature [email protected]ń University of Economics and BusinessAhmad M.

Equality vs. differentiation: on solidarity and justice in social law
No full textThe paper describes the question of the principle of equality in social law against the background of permissible differentiation and its justification. The author refers to the axiology of social law as an instrument of social policy by presenting the function of social law. He discusses the question of social justice as distributive justice, and defines the principle of social solidarity and the principle of the common good as the most important for the healthcare system

Classifier Combination and Selection Methods at the Corporate Bankruptcy Prediction
No full textThe author of this article decided to investigate the efficiency of using classifier combination and selection methods at the prediction of corporate bankruptcy in Poland. The study allowed us to compare the predictions from 4 individual classifiers: linear discriminant analysis, logistic regression, artificial neural network and random forest with the predictions from 9 classifier combination and selection methods. Moreover, the author analyzed the influence of the number of variables in models on performances of the correct classification for all considered methods
Reactivity of the hypothalamic-hypophysal system when certain physical and chemical agents are in operation
No full textUpon the basis of extensive literature, the author discusses in the article the influence of some physical and
chemical factors upon the activity of the neuro-secretive system. Upon studying a number of reports on the
subject, the author reaches the conclusion that physical factors (such as visible, ultra-violet and X-ray
radiation) aa well as chemical drugs and compounds induce in both humans and animals an increase or a decrease of
the secretive activity of neuro-secretive hypothalamic nuclei and of the nerve part of the hypophysis, which
undoubtedly is reflected upon the functioning of other secretion glands, steered by the hypothalamus
