Opis:
Investigating the regime of groundwater levels is one of the main stages of hydrogeological research, which allows quantitative characterization of the process of formation and change of hydrogeological conditions in time. To date, there has been a problem in filling the series of groundwater levels (GWLs) that have gaps. During the formation of time series of data, there are usually gaps in connection with the change in the technique of observing the GWL, the untimely filling of data rows, the lack of the ability to conduct such observations, and others like that. However, it is not possible to completely exclude rows with spaces, as this may lead to inaccurate data while developing forecast and constructing predictive maps of groundwater levels. Therefore, the task is to compare the existing methods of filling the data series with spaces in order to choose the optimum for further work, with their practical verification.

Chronic low back pain affects 50-80% of the population, while its consequences may impair the functioning of patients suffering from it, in many spheres of life . Hope is a factor which may influence coping with pain as well as cognitive reflection of pain experience. The aim of the study has been to check: 1) whether dependencies exist between hope-trait and hope-state and the perception of pain; 2) whether experiencing pain at the time of filling questionnaires matters for the assessment of the level of hope; 3) whether there is interaction between hope, the pain experienced at the moment of investigation, and memory of the intensity of previously experienced pain. 150 patients participated in the study, they all reported aggravation of the chronic low back pain syndrome. The study was a cross-sectional study, based on questionnaires. On the third day of treatment the subjects were given the following questionnaires: Trait Hope Scale, State Hope Scale, and Numerical Rating Scale of Pain to fill. Poor correlation was demonstrated to exist between hope-state and hope-pathways on the one hand, and the intensity of minimum pain level experienced during the first three days of treatment. It has been noted that the presence of pain at the time of filling questionnaires results in reducing the hope-state, but only in those persons, who had experienced severe pain previously. On the other hand, in case of patients who had experienced slight pain previously, the pain present when filling in the questionnaires is conducive to enhanced hope-state. The results of the study confirm the complex character of relations between hope and pain.

Opis:
In a postindustrial economic world, information economies are key components in local, regional and national development. These are service economies, built on the production, consumption and dissemination of information, including education, health care, outsourcing, tourism, sustainability and related human welfare services. We explore the geography/knowledge intersections in Poland’s voivodeships and poviats by using the volumes of information or hyperlinks about selected information economies. Google hyperlinks are electronic knowledge data that can be mapped to highlight the areas of most and least information about certain subject categories. While some mapping results are expected, such as Warsaw and Krakow, being prominent, in other regions there are unexpected gaps within eastern, northern and southern Poland, including some places near major metropolitan centers. There is a significant difference between the cities with poviat rights, which stand out in the number of information on items comparing to the poviats that surround them. The majority of poviats in Mazowieckie voivodeship are surprisingly recognized as core areas on the map of knowledge, nevertheless they are considered undeveloped from the economic point of view.

Opis:
Gapped magnetic components are inherent to applications where conversion of power would force magnetic flux density beyond the saturation point of magnetic materials. A physical discontinuity in a magnetic path, which an air gap represents, signifies a drastic change in its reluctance to magnetic flux. This gives rise to a phenomenon referred to as the fringing effect, which impacts the performance of magnetic components. The fringing flux also affects the physical properties of magnetic components, such as magnetic reluctance and inductance. Since inductance of gapped magnetic components is a function of the size of the air gap, a relatively simple change to the configuration of the air gap or splitting a single gap into a plurality of gaps entails, frequently, a radical change to the magnetic circuit of the component. This paper examines the way the air-gap configuration affects the distribution of the fringing flux and, by extension, magnetic reluctance and inductance. A method to aid the design of multigap inductors is presented based on 3-D electromagnetic modelling as well as measurements. An analytic expression, which closely approximates the required length of quasi-distributed gaps substituting a single gap, is developed.

Opis:
In this paper, we study propagation of electromagnetic wave in negative ternary refractive indices of two-dimensional photonic crystals. We consider two structures with two concentric cylindrical rod and shell in which one of them has negative refractive indices, in positive dielectric background. It is shown that by increasing the diameter of the rod in both structures, we can obtain more and wider band gaps in comparison with the structures in which there is no negative refractive index materials. This increase is more considerable in the first structure, in which the rod has a negative refractive index, in comparison with the second one, where the rod has a positive refractive index.

Opis:
The paper aims to analyse the dependence of the economic and social development of Ukraine on migration factors (human resources and remittances) in the years 2002–2020. It proves the strength of the impact of human resources outflow and remittances on the labour market (employment) and other variables capturing the level of economic and social development. Based on the calculated social and economic development composite indicators the paper detects the migration gaps in the development of the economic system and social domain depending on the human resources outflow and remittances inflow. The results of the empirical research show a positive causal relationship between social development environments and migration and a mixed impact of the migration factor on economic system.

Opis:
The source of clastic material supplied to the epicontinental sea during the Middle and Late Jurassic in the Pomeranian Segment of the northern part of the Mid-Polish Trough is analysed, using deposits from the Rzeczyn PIG-1 borehole that represent the Łyna, Chociwel, Brda, Pałuki, Kcynia and Rogoźno formations. Heavy mineral analysis, including weathering indices (ZTR, GZI, RZI and Q) and standardised scores for each mineral species, shows that each formation is characterized by a different heavy minerals association. In each association, transparent minerals include both ultrastable minerals (zircon, tourmaline and rutile), occurring in various proportions, and unstable minerals. This indicates that deposits subject to earlier multiple reworking were eroded from the surrounding landmasses. Most probably these deposits represented Triassic rocks, although fresh weathering covers were also eroded. The main direction of clastic material supply was from the N and NW, and to a lesser degree from the NE. The main reasons for changes in the source areas were probably sea level oscillations, while during regressions, exposed parts of the seabed became source areas of clastic material. Conversely, during transgressions, parts of the seabed became cut off from the supply of clastic material from eroded landmasses.

Opis:
The new linguistic science lacunology has come into prominence recently. The lacunae studies embrace sociolinguistics, nonverbal semiotics and applied linguistics studies. The re-search of terms of lacunology (lacunicon) is devoted to empty places in the structure of the contrasting languages and the ways of zero verbalization in the written and oral discourse. The empty category of the category “lacunarity” has been studied by the Canadian transla-tors Jean Paul Vinay (1910-1999) and Jean Darbelnet (1904-1990), the Russian pioneers of lacu-nology Yuriy Sorokin (1936-2009) and Gulchera Bikova and their followers. The research has resulted in the cognitive mind mapping. It turned out that lacunarity has several vectors, e.g. lacunae of language (i), lacunae of speech (ii), lacunae of cognition (iii) to be further discussed in the article. The basic terms of lacunicon are described. These are a pause in syntagmatics, a linguistic gap in paradigmatics, a lacuna in both diachronic and synchronic regimes.

Opis:
In the course of my research at PHD at the AMU University in Poland, I was exposed to patterns of communication between the school and the parents of the students. It turns out that these patterns change frequently: if in the past it was customary to write to parents in a contact notebook about the student’s behavior at school, or make a call through Telephone line. Now we are exposed to new patterns of communication that may improve the relationship between the school and the parents, but on the other hand there are dangers and challenges that, if not considered, may harm the parents’ involvement or contact with them. In recent years, with digital technological developments (Internet, smartphones, social networks), there has been a significant change in communication patterns between parents and teachers. The communication is immediate, the parents are connected to the school Site, and they are updated online by email, the WA messages, groups, etc. In this article I will examine the changes in communication between the school and parents and the significance of these changes. I will also relate to the gaps created between populations that can’t afford some of these technologies and the intergenerational gap that is growing as a result of technological changes and their impact on students, parents and teachers

Opis:
New seismic profiles have been used to revise earlier interpretations of the Ordovician-Silurian bound ary beds be tween Saaremaa and Gotland. Atrans-Baltic reflector with erosional fea ures (S2) above the erosional Ordo vician-Silurian boundary reflector (S1) correlates with the bound ary between the Raikküla and Adavere stages. The sporadic reflector or2 below the S1 reflector off shore from Gotland represents the erosional boundary between the Pirgu and Porkuni stages. Three stratigraphic gaps occur in the Ordovician-Silurian boundary beds off shore from Gotland. The amount of eroded rocks between the Pirgu and Porkuni stages, the Ordovician and Silurian systems and the Raikküla and Adavere stages can change rapidly. Consequently, the thick ness and stratigraphy of the Ordovician-Silurian boundary beds around Gotland can change considerably across short distances. The O4-5-S1 unit off shore from Gotland, including carbonate build ups and erosional incisions infilled with Porkuni strata, belongs facially to the transi ional belt between the Estonian Shelf and the Livonian Tongue. The thick ness changes in the S1-S2 unit (Juuru and Raikküla stages) indicate an extensive subma rine erosional channel, streching from north of Estonia across the Baltic Sea and central Gotland, which developed in the Baltic Basin along a shelf to deep-basin transect dur ng Llandovery time.

Opis:
Precise Point Positioning (PPP) is a technique used to determine the position of receiver antenna without communication with the reference station. It may be an alternative solution to differential measurements, where maintaining a connection with a single RTK station or a regional network of reference stations RTN is necessary. This situation is especially common in areas with poorly developed infrastructure of ground stations. A lot of research conducted so far on the use of the PPP technique has been concerned about the development of entire day observation sessions. However, this paper presents the results of a comparative analysis of accuracy of absolute determination of position from observations which last between 1 to 7 hours with the use of four permanent services which execute calculations with PPP technique such as: Automatic Precise Positioning Service (APPS), Canadian Spatial Reference System Precise Point Positioning (CSRS-PPP), GNSS Analysis and Positioning Software (GAPS) and magicPPP - Precise Point Positioning Solution (magicGNSS). On the basis of acquired results of measurements, it can be concluded that at least two-hour long measurements allow acquiring an absolute position with an accuracy of 2-4 cm. An evaluation of the impact on the accuracy of simultaneous positioning of three points test network on the change of the horizontal distance and the relative height difference between measured triangle vertices was also conducted. Distances and relative height differences between points of the triangular test network measured with a laser station Leica TDRA6000 were adopted as references. The analyses of results show that at least two hours long measurement sessions can be used to determine the horizontal distance or the difference in height with an accuracy of 1-2 cm. Rapid products employed in calculations conducted with PPP technique reached the accuracy of determining coordinates on a close level as in elaborations which employ Final products.

Opis:
The scan-line corrector (SLC) of the Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor failed in May 2003, and this abnormal functioning of SLC resulted in about 22% of the pixels per scene without being scanned. By filling the un-scanned gap by a good technique will help in more use of ETM+ data for many scientific applications. While there have been a number of approaches developed to fill in the data gaps in ETM+ imagery, each method has shortcomings, especially they require SLC-on (images acquired before SLC-off anomaly) imagery for the same location to fill the gaps in SLC-off (images acquired after SLC anomaly) image. To overcome such shortcomings this study proposes an alternative interpolation method based on the partial derivative. This case study shows that this technique is very much useful to interpolate the missing pixel values in the SLC-off ETM+ data.

Towards the Methodology for Extending Princeton WordNetThe paper presents the methodology and results of the first, pilot stage of the extension of Princeton WordNet, a huge electronic English language thesaurus and lexico-semantic network based on synsets, ie. sets of synonymous lexical units, or lemma sense pairs. The necessity for such extension arose in the course of mapping plWordNet (Polish WordNet - Słowosieć) onto Princeton WordNet, which produced a large number of inter-lingual hyponymy links signalling differences in the structure and lexical coverage of the two networks. The proposed strategy uses I-hyponymy links as pointers to presumed gaps in the lexical coverage of PrincetonWordNet and offers strategies of filling them in with new lexical units and synsets.

Opis:
The goal of this paper is to identify and criticize an intuitive way of thinking about gaps in the law, which I dub “the input view”. In this approach, legal gaps play the role of premises in legal reasoning in the sense that they trigger the application of, otherwise impermissible, methods of interpretation. The input view thus rests on a sharp distinction between the following two stages of legal interpretation: identification of a legal gap and filling it. The central motivation for embracing this view is to limit the scope of judicial discretion. I argue that the input view fails by its own lights by showing a class of cases in which it actually increases the scope of judicial discretion. My argument exploits the observation that, on any account of legal gaps available to the proponent of the input view, there will be cases in which a judge has discretion to say whether it involves a legal gap or not.
Celem niniejszego tekstu jest identyfikacja oraz krytyka intuicyjnego sposobu myślenia o lukach prawnych, który określam mianem „przesłankowego ujęcia”. Na gruncie tego podejścia, luki prawne odgrywają rolę przesłanek w rozumowaniu prawniczym – wystąpienie luki stanowi okoliczność warunkującą zastosowanie, niedopuszczalnych w innych okolicznościach, nieformalistycznych metod interpretacji prawniczej. Ujęcie przesłankowe opiera się zatem na ścisłym rozgraniczeniu dwóch etapów interpretacji prawniczej: etapu identyfikacji luki oraz etapu jej wypełniania. Główną motywacją dla tego poglądu jest chęć ograniczenia dyskrecjonalności sędziowskiej. W niniejszym tekście stawiam tezę, że ujęcie przesłankowe nie jest w stanie podołać temu zadaniu, ponieważ istnieje klasa przypadków, w których prowadzi ono do poszerzenia zakresu dyskrecjonalności sędziowskiej. Mój argument korzysta z obserwacji, że – niezależnie od przyjętego ujęcia luk prawnych – formalista zmuszony będzie przyznać istnienie stanów faktycznych, w których decyzja, czy mamy do czynienia z luką prawną, leży w zakresie władzy dyskrecjonalnej sędziego.
