Opis:
The authors of the article pay their attention to the lack of a generally accepted classification of the cartographic presentation methods. The classification, which was described in the Ratajski’s handbook (1989) in the mostly extensive way, is commonly used in the Polish literature. According to the authors, it would be appropriate to modify one of the types of symbols (quantitative ones) as an independent method of data presentation at the quantitative level, in addition to the method of diagram, choropleth, dot method and isoline one.

Opis:
This article presents the main recent developments in migration trends to and from Belarus. It studies these trends via the migration systems theory lenses, according to which Belarus belongs to the Eurasian migration system. The most significant migration flows are directed towards Russia, due to the existence of the Union State. However, over the last decade, Belarusian statistics have shown a gradual transformation in the direction of these migration flows. After the recession in Russia in 2015, the number of emigrants from Belarus to EU countries increased. The most significant changes have occurred in the migration dynamics between Belarus and Poland and Lithuania. The existence of the Pole’s Card makes it more difficult to measure the number of Belarusian immigrants in Poland, therefore, I provide a comparative analysis of Belarusian and Polish statistics in order to show a more realistic picture of the number and structure of Belarusian emigrants and the problem of underestimation in the sending country. Particular attention is paid to the consequences of the political situation in Belarus after 2020; this has become an additional push factor for emigrants and may also lead to a further reduction of Belarusian migratory links within the Eurasian migration system. Thus, the statistics for 2021 show a significant increase in the number of Belarusian emigrants to the EU, while emigration to Russia has remained at the same level.

Ukraine
Opis:
Ukraine remains today one of the main migrant sending countries in Europe, with thousands of Ukrainians working in Czechia, Italy, Poland and Russia. In this regard, Ukraine shares the previous experience of Central European countries such as the Baltic States, Poland and Slovakia, that in the 1990s and early 2000s registered first temporary, and later permanent, outflows. In more recent years, however, many Central and Eastern European countries started to register increasing numbers of immigrants and some of them have switched from net sending to net receiving migration regimes. The objective of this article is to discuss the possibility of a similar turnaround in Ukraine; to this end, we investigate the main quantitative data on migration from and to Ukraine, and interpret this information in the light of selected theoretical approaches that have been used to explain migration in Central and Eastern Europe. The available data reveal high levels of labour emigration of both temporary and permanent character, the increasing propensity of migrants to settle down in the host countries, and the growing involvement of the youngest cohorts in the emigration. Despite this evidence we argue that the current situation by no means constitutes a premise for reversing the outflow from Ukraine. We conclude that the most recent improvements in general economic indicators will not lead to high levels of immigration without an active labour market policy towards foreigners.

Opis:
The Maastrichtian sediments of northern Iraq are rich in larger benthic foraminifera. Among them, the genus Loftusia is well-known one because of its significant palaeogeographic distribution across the Mediterranean and Middle East. In this study, observations of abnormal test shapes, species recognition criteria and endoskeleton characteristics of Loftusia are discussed, based on the new material from north-eastern Iraq. The following species of Loftusia are described: Loftusia elongata Cox, L. persica Brady, Loftusia morgani Douvillé, L. anatolica Meriç, L. matsumarui Meriç and Görmüs, L. minor B Cox, L. ketini B Meriç and L. kahtaensis Meriç, Loftusia minor A Cox, L. oktayi Meriç and L. baykali Meriç. The predominant species are Loftusia elongata, L. morgani and L. baykali. Skewed abnormal individuals and epidermal parts of the endoskeleton structure are also interesting aspects to note. Quantitative data obtained for Loftusia allow us to better understand and interpret species identification criteria, abnormal occurrences and the endoskeleton structure.

Opis:
The article presents some proposals that might contribute towards improving quality while results of statistical analyses are presented in Polish publications within history and related disciplines. According to the author nowadays there are no clear standards determining the rules of such presentations, which often leads to a limited comparability of results and makes it impossible to apply the techniques of data meta-analysis, and insome cases also leads to serious methodological errors. The proposals included in the text consists of the following postulates: 1) to inform the reader of the number of the populations and subpopulations investigated; 2) to make a greater use of statistical measures that describe the distribution of the analysed communities; 3) to standardise the convention of recording such measures; 4) to inform the reader about the size of the standard errors; 5) to apply the commonly accepted rules concerning data grouping; 6) to take into account the spatial dimension of the analysed phenomenon, which should be presented in the form of maps and plans; 7) to urge the authors of academic texts to make public their data sets.

Opis:
Danian–Selandian (D–S) planktic foraminiferal taxonomy and paleoecology, including the most problematic index−species of biochronological schemes, are here revised based on qualitative and quantitative data from the Caravaca and Zumaia sections, Spain. As a first step the morphological and microtextural diagnostic characters are revised in order to achieve appropriate morphological distinctions of the investigated species. The analysis of latitudinal preferences of the planktic foraminiferal species deduced from a comparison of their relative abundances at Caravaca (western Tethyan subtropical waters) and Zumaia (central North Atlantic warm temperate waters) in suite with a statistical comparison of quantitative stratigraphic distributions of the species at Caravaca have shown several divergences in their patterns of spatio−temporal distribution (i.e., in their latitudinal preferences and quantitative stratigraphic distributions). This analysis allowed taxonomical separation of 41 species from the following genera: Eoglobigerina, Subbotina, Parasubbotina, Globanomalina, Luterbacheria, Acarinina, Igorina, Morozovella, Praemurica, Chiloguembelina, and Zeauvigerina. Morphologically convergent species pairs such as Acarinina trinidadensis and Praemurica inconstans, Acarinina praecursoria and Acarinina uncinata, Morozovella conicontruncata and Morozovella angulata, or Morozovella cf. albeari and Igorina albeari, are well differentiated using aforementioned criteria. Since some of the species are index−taxa, the taxonomic refinements are essential to clarify and compare the planktic foraminiferal zonations from the Danian–Sealandian transition. A new lower/higher (L/H) latitude taxa ratio is proposed for paleoclimatic interpretations based on the paleoecological and quantitative studies. Fluctuations in L/H ratio in the Caravaca section suggest three climate warming events during the D–S transition, one of them probably occurring at the D–S boundary.

The development of advanced spatial-positioning systems for medical monitoring and emergency response using RFID and Wi-Fi technologies is a current research focus of many healthcare organizations. The goal of such system is to support real-time location tracking of medical equipments and personnel in hospital settings using RTLS technology. This paper presents a spatial-temporal data analysis based on data collected at the W21C of Foothills Hospital, Calgary, Canada. The collected data, comprising real-time observations and tracking paths, has been used to perform advanced statistical pattern analysis and visualization of work-flow patterns in health care system. From this analysis, we bring forward some insights into medical resource, asset and facility utilization in a clinical care ward of a regional healthcare organization. This gained knowledge could be used as one of the inputs in improving patient care, responsiveness, and infection control practices.

Wielkie zbiory danych typu Big Data są obecnie nieodłącznym elementem badań w wielu dziedzinach nauki – w tym w geografii społeczno-ekonomicznej. Znajdują one szereg zastosowań, zarówno wnosząc możliwość analizy nowych danych w klasycznych problemach badawczych, jak i same w sobie będąc nowym przedmiotem badań oraz pozwalając na badanie cyfrowych geografii. Jednocześnie Big Data krytykuje się za niejednorodność, brak reprezentatywności, nierówność reprezentacji czy też problemy etyczne. Z tego powodu zwracamy uwagę na szereg dylematów związanych z obecnością Big Data w praktyce badawczej, sugerując istotną rolę krytycznego podejścia do ich zastosowania w praktyce badawczej.
Big Data are inseparable part of the current research methodology in many scientific disciplines – including socio-economic geography. They are being used as a new data in old research problems, as a new research objects and as a means to investigate digital geographies. Big Data are being criticized for lack of representativeness and problematic representation, heterogeneity, and ethical issues. Despite these problems, their presence as a part of the geographical research methodology is increasingly frequent. We propose a set of recommendations that in our view allows a researcher to critically assess the validity of utilizing Big Data in a given research project.

This paper describes the problem of planning cellular network base stations with optimization to traffic requirements. This research problem was a main incentive to add some development to the theory of association rules. The new form of quantitative and multi-dimensional association rules, unlike other approaches, does not require the discretization of real value attributes as a preprocessing step. They are discovered with data driven algorithm that gives precise and complete results and has polynomial complexity for a given dimensionality.

Opis:
W badaniach prowadzonych dotychczas przez autorów artykułu ocena jakości danych lustrzanych w wymianie towarowej między krajami Unii Europejskiej (UE) opierała się na wartości towarów. Analogiczne podejście stosuje wielu badaczy. Celem badania omawianego w artykule jest ocena jakości danych dotyczących obrotu wewnątrzunijnego na podstawie nie tylko wartości, lecz także ilości towarów. W analizie rozbieżności danych w handlu między krajami UE, ze szczególnym uwzględnieniem Polski, wzorowano się na wybranych metodach badania znanych z literatury przedmiotu. Podejście zarówno wartościowe, jak i ilościowe stanowi wkład własny autorów w metodykę badawczą. Zaproponowano wskaźniki jakości danych oraz wykorzystano dane dotyczące masy towarów. Analizie poddano informacje na temat obrotu towarowego między krajami unijnymi w 2017 r. pochodzące z bazy Eurostatu Comext. Badanie dynamiki obejmowało również lata: 2005, 2008, 2011 i 2014. Wyniki analizy pokazały, że ogółem udział wywozu z Polski towarów do danego kraju na obszarze UE jest różny dla danych wyrażonych wartościowo (wartość towarów) i ilościowo (masa towarów). W badaniu jakości danych lustrzanych należy zatem stosować oba podejścia.
In the research carried out to date by the authors of the article, the assessment of the quality of mirror data in the exchange of goods between European Union (EU) countries was based on the value of goods. A similar approach is applied by many researchers. The aim of the research discussed in the article is to assess the quality of data relating to intra-EU trade based on not only the value, but also on the quantity of goods. The analysis of discrepancies in data relating to trade between EU countries, with a particular emphasis on Poland, was based on selected research methods known from literature. Both the value-based and the quantitative approach constitute the authors' contribution to the development of research methodology. Data quality indicators were proposed and data pertaining to the weight of goods were used. Information on trade in goods between EU countries in 2017 obtained from Eurostat's Comext database was analysed. The research relating to the dynamics also covered the years 2005, 2008, 2011, and 2014. The results of the analysis demonstrated that the total share of export of goods from Poland to a given country within the EU is different for data expressed in value (value of goods) and in quantity (weight of goods). Therefore, both approaches should be applied in the study of the quality of mirror data.
