In this article we consider the possible sets of distances in Polish metric spaces. By a Polish metric space we mean a pair (X, d), where X is a Polish space (a separable, completely-metrizable space) and d is a complete, compatible metric for X. We will consider two aspects. First, we will characterize which sets of reals can be the set of distances in a Polish metric space. We will also obtai...

We introduce a notion of Polish structure and, in doing so, provide a setting which allows the application of ideas and techniques from model theory, descriptive set theory, topology and the theory of profnite groups. We define a topological notion of independence in Polish structures and prove that it has some nice properties. Using this notion, we prove counterparts of some basic results from...

Three groups of data entry female visual display terminal (VDT) workers from Norway (n = 30), Poland (n = 33) and the USA (n = 29) were compared. Before intervention, the Norwegian group reported more neck pain compared with the Polish group. The Polish group reported less shoulder pain than both the U.S. and the Norwegian groups. The clinical examination documented fewer symptoms and signs of ...

AIM The aim of the study was to assess the self-reported oral health behaviour of Scandinavian and Polish medical students studying in Poland. METHODS Three hundred and fifty subjects took part in the questionnaire survey. They were the 4th to 6th year Scandinavian and Polish medical students attending the same medical school. Test-retest reliability demonstrated an accepted level of kappa > ...

In this article we propose an extension to the variation ngram based method of detecting annotation errors. We also show an approach to nding anomalies in the morphosyntactic annotation layer by using association rule discovery. As no research has previously been done in the eld of morphosyntactic annotation error correction for Polish, we provide novel results based on experiments on the large...

The aim of the present contribution was to examine the factors influencing the prosodic processing in a language with predictable word stress. For Polish, a language with fixed penultimate stress but several well-defined exceptions, difficulties in the processing and representation of prosodic information have been reported (e.g., Peperkamp and Dupoux, 2002). The present study utilized event-re...

AIM The study aimed at providing the psychometric properties of Polish version of Peters et al. Delusion Inventory (PPDI) (1999) and assessing the prevalence of delusion-like experiences among healthy subjects in the Polish population. METHODS Polish version of PDI was developed on the basis of back translation procedure. The scale was completed by 421 adult subjects. On the basis of the scor...

The aim of this paper is to compare clitic climbing (CC) in Polish and Romance and then provide an HPSG account of CC in Polish. We discuss CC in the complementizerless verbal complexes, which we call verb clusters (VC). Both the behaviour of Polish clitics and properties of VC are different in Polish and Romance. Although we apply (‘standard’ for HPSG) lexical encoding to account for CC, our a...

MRI magnets generates strong and uniform magnetic fields within the field of wiev, but spatial field gradients are present outside this central region, and as consequence people moving within magnet room experience time-varying magnetic field inducing electric fields and currents in tissues. Aim of this study is the assessment, through direct static field measurements and model based calculatio...
