    Opis:
    Research background: As a system of official EU statistics, Intrastat contains data collected by Member States aggregated by Eurostat on the Union's level in the form of COMEXT database. Country-level data are based on declarations made by businesses dispatching or acquiring goods from other EU Member States. Since the same transaction is declared twice - as an ICS in one country and at the same time as an ICA in another country by the partner - the database contains mirror data. Analysis of mirror data lets us assess the quality of public statistics data on international trade. Purpose of the article: The aim of the article is to rank EU Member States according to quality of data on intra-Community trade in goods collected by Intrastat. Foreign trade stimulates economic development on one hand and is the development's reflection on the other. Thus it is very important that official statistics in this area be of good quality. Analysis of mirror data from partner states in intra-Community trade in goods allows us to claim that not every Member State pro-vides data of satisfactory quality level. Methods: We used the authors' methodology of assessing quality of mirror data. These include data asymmetry indices, both proposed by Eurostat and the authors' own proposals. We have also examined the changes in the above mentioned rankings over time. Findings & Value added: The result of the survey is ordering of EU Member States according to the quality of data on intra-Community trade in goods. The rankings are presented for the period of 2014-2017, during which there were 28 Member States of the EU. Changes in distinct countries' positions were shown as a result of changes in overall quality of statistical data collected in these countries. The research methodology can be used in the process of monitoring data quality of the Intrastat system.

    Opis:
    Research background: Some statistics are of a bilateral nature. This is how foreign trade data is organized. They are recorded both in the supplier and recipient countries, hence they are called mirror data. The data recorded at both trading partner countries are not the same for different reasons. Such differences between data on the same groups of transactions are often referred to as the asymmetry of mirror data. The information about the value of the flows of goods are of great importance in economic analyses and therefore their quality is particularly important. Purpose of the article: The aim of this paper is to present a new measure of data asymmetry - the aggregated quantity index with value-based weights. Methods: The proposed measure combines the quantity and the value of turn-over in individual trade relations. Such a measure makes it possible to eliminate basic deficiencies in value-based measures, while considering the specificity of trade in individual countries. The proposed measure of data asymmetry was confronted with several measures present in the literature and previously used by the Authors. The numerical example uses Comext data on intra-Community trade in 2017 provided by Eurostat. Findings & Value added: The proposed measure performs better than all the previously used data asymmetry indices. It is to some extent immune to exchange rate differences and inconsistencies resulting from the inclusion of transport and insurance costs in the value of goods. In addition, it gives lower weights to unimportant trade directions than other data asymmetry indices. Since the new index has proved to be better than the measures previously used, it is worth applying to those trade relations where the data are not de-rived from customs documents, but from declarations made by businesses, as in the case of intra-Community trade.

    Opis:
    Research background: Transactions in international trade of goods are recorded in two sources, on the side of the seller's country and on the side of the buyer's country. The confrontation of such data makes it possible to measure their quality. An inconsistency between the data is called mirror data asymmetry. Purpose of the article: The aim of the paper is to adapt the methods developed by the Authors to study mirror data asymmetry to commodity group markets examination. The quality of data on trade within specific commodity groups (CN chapters) in intra-Community trade was compared. The data were aggregated by country. The indicators used allow for the indication of commodity groups with high mirror data compatibility and those with data asymmetry between intra-Community supplies (ICS) and acquisitions (ICA). Moreover, the commodity groups for which the value-based and quantity-based approaches give different results have been identified. Methods: Based on the literature on the subject and their own research, the Authors have developed a group of methods for studying the asymmetry of mirror data. The proposed indicator formulas are based on various data aggregation approaches. The research used data on intra-Community supplies and acquisitions of goods broken down into 97 chapters of the Combined Nomenclature (CN). Differences between the ICS and ICA in particular commodity groups were aggregated for all pairs of EU countries. The data comes from the Comext database, provided by Eurostat. Findings & value added: The results of the analysis are rankings of the Combined Nomenclature (CN) chapters by the quality of data on ICS and ICA. Lists of CN chapters have been created for discrepancies both in value and weight of goods. Thus, areas of necessary intensification of the work of public statistics services to improve data reliability were identified.

    Opis:
    Statistical data on foreign trade are collected in all EU member states separately and then passed on to Eurostat where the data are aggregated. Continuous actions are to ensure that all datasets collected at national level are fully comparable. The aim of the paper is to provide a classification as well as an ordering of CN chapters (2-digit codes) according to the quality of data on intra-Community trade of goods. Data were taken from Eurostat’s COMEXT database. In ordering the chapters, we utilized the distance from the ideal solution with GDM as the distance measure. The study reveals a structure of goods subject to intra-Community trade that is supplementary to the official nomenclature. In addition, we provided CN chapters ordering according to the overall level of irregularities in reported mirror values of ICS and ICA. The results we obtained are of practical value for both researchers and authorities interested in foreign trade.

    Opis:
    Wprowadzenie w Polsce systemu INTRASTAT wraz z wejściem naszego kraju do Unii Europejskiej 1 kwietnia 2004 roku spowodowało nałożenie na podmioty prowadzące obrót towarowy z innymi państwami członkowskimi UE obowiązku przekazywania informacji o zrealizowanych przez nie obrotach. Dane o handlu wewnątrzwspólnotowym z poszczególnych krajów gromadzone są przez Eurostat i udostępniane w postaci bazy Comext. W celu określenia jakości danych o wewnątrzwspólnotowej wymianie towarowej zbadano różnice między deklarowanymi wartościami wywozu towarów z Polski i przywozu z Polski do pozostałych krajów unijnych. Celem artykułu jest analiza jakości danych o polskim handlu wewnątrzunijnym w podziale na działy nomenklatury scalonej CN oraz utworzenie rankingu działów pod względem jakości danych, rozumianej jako rozbieżność między danymi lustrzanymi. Pomiaru jakości danych dokonano z wykorzystaniem zagregowanych wskaźników rozbieżności. Zaprezentowano ranking działów według wyznaczonych wartości wskaźników, osobno dla wewnątrzwspólnotowych dostaw towarów (WDT) i wewnątrzwspólnotowych nabyć towarów (WNT). Wykorzystano dane z bazy Comext dotyczące transakcji wewnątrzwspólnotowych polskich eksporterów w 2017 roku. Efektem przeprowadzonego badania było wskazanie działów o największych względnych rozbieżnościach między danymi lustrzanymi (najniższej jakości danych). W działach o najniższej jakości wskazano wewnętrzną strukturę rozbieżności według krajów oraz pozycji klasyfikacji towarowej. Problem jakości danych dotyczących handlu wewnątrzwspólnotowego jest poruszany w Polsce jedynie w publikacjach GUS‑u. Brak jest prac naukowych w tym zakresie. Dlatego też autorzy postanowili wypełnić tę lukę i prowadzić badania nad źródłami informacji, które są podstawą wielu analiz gospodarczych.
    Adopting the Intrastat system in Poland on its EU‑accession on 1st May, 2004 imposed a new obligation on companies trading goods within the EU. They are obliged to provide information on their intra‑Community trade in the form of monthly declarations. Data on intra‑Community trade from all Member States are collected by Eurostat and disseminated in the form of the Comext database. In public statistics, special attention is being paid to data quality. It is constantly monitored and certain actions are taken to improve it. In order to assess quality of data on intra‑Community trade, the authors have calculated differences between declared values of supplies of goods from Poland as well as foreign acquisitions originating in Poland. The aims of the paper are an analysis of quality of data on Polish intra‑Community trade in goods within Combined Nomenclature chapters as well as creating a ranking of chapters with regard to data accuracy (one of quality dimensions) which we define in terms of divergence between mirror data. Data accuracy was measured with the use of aggregate data quality indices. The ranking of Combined Nomenclature (CN) chapters was presented according to the calculated index value for both intra‑Community supplies of goods (ICS) and intra‑Community acquisitions (ICA). We utilised data on Polish exporters’ transactions from 2017 from the Comext database. In the research results, we indicate those chapters for which large relative discrepancies between mirror data are observed (thus data quality is low). For chapters with low data quality, we present inner structures of discrepancies by country and by CN position. The problem of quality of data on intra‑Community trade is addressed in Poland only in publications of the Central Statistical Office/Statistics Poland. There are no scientific publications on this subject. Therefore, the authors decided to fill this gap and conduct research on sources of information which is the basis for many economic analyses.

    Opis:
    W systemie INTRASTAT zbierane są dane statystyczne dotyczące wymiany towarowej między krajami UE. Eurostat agreguje dane pochodzące z poszczególnych państw członkowskich. Specyfika procesu pozyskiwania danych różni się w poszczególnych krajach, w związku z czym dane lustrzane (dotyczące w założeniu tych samych transakcji, odnotowanych w statystyce kraju wywozu i kraju przywozu) często się nie pokrywają. Celem przeprowadzonych analiz była ocena jakości danych o wewnątrzunijnej wymianie towarowej krajów „starej” piętnastki i „nowych” członków UE ze wskazaniem, które kierunki w największym stopniu wpłynęły na występowanie obserwowanych różnic w danych lustrzanych. Artykuł jest kontynuacją badań jakości danych dotyczących handlu zagranicznego.
    The Intrastat system is used for gathering statistical data on trade in goods between the EU Member States. Data from all the Member States are aggregated by Eurostat. Specifics of the data collection process are different in different countries and that is why mirror data (regarding by default the same transactions revealed in statistics of both the acquirer and supplier country) often do not match. The goal of the analysis conducted was to assess the quality of data on intra‑Community trade in goods between the ‘old’ fifteen and the ‘new’ EU Member States as well as to point out these directions that influenced the observed differences in mirror data the most. The paper is a follow‑up of previous research on the quality of foreign trade data.

    Opis:
    The content presented in the article is a continuation of the research on the quality of data concerning intra-Community trade. Several measures used in literature to assess differences between mirror data are presented. The research was inspired by the works by Morgenstern (1963), Federico and Tena (1991), and Ferrantino and Wang (2008). These previous works contain some directions on how Intrastat data should be analysed. Based on this the analysed data on intra-Community trade in goods for 2017. The dynamics of intra-Community trade were also examined. The obtained results can be utilised by practitioners from both the domain of official statistics and the revenue authorities. In the article discrepancies in data on Polish foreign trade are studied in the context of Poland-EU partner country (bilateral relations) and Poland-EU partners (one-to-many relations). The aim of the article is to compare the results of selected literature studies with those obtained on the basis of the analysis of the latest data on intra-Community trade in Poland (mainly in 2017) and EU member states.

Inspiracją do przeprowadzonych badań były publikacje autorów takich jak: Morgenstern (1963), Federico i Tena (1991) oraz Ferrantino i Wang (2008). To w nich znaleziono pewne wskazówki. Na tej podstawie analizie poddano dane dotyczące obrotu towarowego między krajami unijnymi w 2017 roku. Zbadano także zmiany zachodzące w czasie. Wyniki takich badań mogą być wykorzystane w zakresie zarówno statystyki publicznej, jak i podatkowym. W artykule podjęto temat analizy rozbieżności danych w handlu Polski w relacjach Polska–kraj UE (relacje dwustronne) i Polska–kraje UE (relacja kraj–kraje, nazwana zagregowaną). Celem badania jest porównanie wyników wybranych badań literaturowych z wynikami uzyskanymi na podstawie analizy najnowszych danych dotyczących obrotu wewnątrzwspólnotowego Polski (głównie 2017 rok) oraz krajów unijnych.

    Opis:
    Sorption studies, to determine the CO2 sorption capacity of coal, were carried out using eight ortho-lignite samples of different lithotypes, to investigate the possibility of CO2 storage in lignite deposits. Equations determining a number of parameters and indicators used to delineate the experimental data and to differentiate the samples examined include: Langmuir isotherms; the Dubinin-Radushkevich (DR) equation that describes the theory of volume filling of micropores; and the Brunauer, Emmett and Teller (BET) equation used to calculate the volume and surface area of a monolayer. The results obtained were compared with the petrographic composition and ultimate and proximate analysis of lignite. There is a large correlation between sorption and petrographic composition, a positive impact of the Gelification Index on the sorption process and a clear relationship between the sorption (Langmuir and DR) and ash content. The best CO2 sorption properties were found for xylo-detritic and detro-xylitic lignites. Based on the tests carried out, a preliminary assessment of the suitability of lignite for CO2 storage can be made.

    Opis:
    Introduction: The World Health Organization report (2014) recommends the introduction of national programs for suicide prevention. However, the research on their effectiveness is scarce. As a result, policy makers do not have sufficient data for their decisions on the appropriate level of investment in suicide prevention. It is of great importance to know whether the introduction of a national prevention program results in a reduction in suicide rates, and if so, in what age groups and over what period of time after the announcement of the program. Sweden introduced the first suicide prevention program in 1995. It was then modified in 2008, and most recently in 2015. Objectives: The aim of this study was to answer the question about the impact of the suicide prevention program in Sweden (2008) on the total suicide rate as well as the age- and gender-specific suicide rates in the subsequent years. Material and methods: The study provides the overview of the suicide prevention program and suicide rates in Sweden in males and females, in the age groups 0–24, 25–44, 45–64 and over 65, 1, 3 and 6 years before and after the introduction of the national program for suicide prevention. The study presents the statistical analysis of changes in average suicide rates following the announcement of the Swedish National Program for Suicide Prevention 2008 with reference to chosen periods. Conclusions: The Swedish National Program for Suicide Prevention did not result in the reduction of suicide rates in the year after its introduction, whereas suicide rates decreased in all groups, except for the youth (under 24 years old), in 2009–2011 and 2009–2014.
    Wstęp: Choć raport Światowej Organizacji Zdrowia (2014) zaleca wprowadzenie krajowych programów zapobiegania samobójstwom, niewiele jest badań nad ich efektywnością. W rezultacie decydenci nie mają wystarczających danych do podejmowania decyzji w sprawie odpowiedniego poziomu finansowania inwestycji mających na celu zapobieganie samobójstw. Musimy wiedzieć, czy wprowadzenie narodowego programu zapobiegania prowadzi do redukcji liczby samobójstw, a jeśli tak, to w jakich grupach wiekowych i w jakim czasie po ogłoszeniu programu. Szwecja wprowadziła pierwszy program zapobiegania samobójstwom w 1995 roku, następnie modyfikowała go w 2008, a ostatnio w 2015 roku. Cel badania: W badaniu starano się uzyskać odpowiedź na pytanie dotyczące wpływu szwedzkiego programu zapobiegania samobójstwom z 2008 roku na liczbę samobójstw w kolejnych latach w zależności od wieku i płci. Materiał i metody: Badanie przedstawia przegląd programu zapobiegania samobójstwom i wskaźników samobójstw u mężczyzn i kobiet w Szwecji w grupach wiekowych 0–24, 25–44, 45–64, ponad 65 lat w ciągu roku, 3 oraz 6 lat przed i po wprowadzeniu krajowego programu zapobiegania samobójstwom. Zaprezentowano analizę statystyczną zmian uśrednionego wskaźnika samobójstw po ogłoszeniu szwedzkiego krajowego programu zapobiegania samobójstwom w 2008 roku w odniesieniu do wybranych okresów. Wnioski: Szwedzki krajowy program zapobiegania samobójstwom nie spowodował zmniejszenia liczby samobójstw w ciągu roku po jego wprowadzeniu, natomiast wskaźnik samobójstw zmniejszył się we wszystkich grupach z wyjątkiem młodzieży (poniżej 24. roku życia) w latach 2009–2011 i 2009–2014.

    Opis:
    One of the numerous calcium-involving processes in mammalian cells is store-operated calcium entry (SOCE) - the process in which depletion of calcium stores in the endoplasmic reticulum (ER) induces calcium influx from the extracellular space. Previously supposed to function only in non-excitable cells, SOCE is now known to play a role also in such excitable cells as neurons, muscles and neuroendocrine cells and is found in many different cell types. SOCE participates not only in processes dependent on ER calcium level but also specifically regulates some important processes such as cAMP production, T lymphocyte activation or induction of long-term potentiation. Impairment of SOCE can be an element of numerous disorders such as acute pancreatitis, primary immunodeficiency and, since it can take part in apoptosis or cell cycle regulation, SOCE may also be partially responsible for such serious disorders as Alzheimer disease and many types of cancer. Even disturbances in the 'servant' role of maintaining ER calcium level may cause serious effects because they can lead to ER homeostasis disturbance, influencing gene expression, protein synthesis and processing, and the cell cycle.

    Opis:
    Objectives: The aim of this article is to assess the health behaviors of Polish Army soldiers participating in the National Health Programme 2016–2020 in relation to types of armed forces, BMI and selected demographic factors. Material and Methods: Anthropometric and questionnaire data were obtained in a group of 1229 soldiers of the Polish Armed Forces (PAF) from military units from all over Poland. Health behaviors patterns were assessed using the Health Behavior Inventory (HBI), developed by Juczyński. Results: The HBI of PAF soldiers was 79.9±12.68, indicating an average score. Statistically significant differences were found in the HBI values and in the individual categories of health behaviors according to the type of armed forces. The highest scores in each category of health behaviors were obtained by the Air Force (AF) soldiers. The lowest HBI score was obtained by the Land Forces and Territorial Defence Forces soldiers. Soldiers with higher education obtained significantly higher scores in such health categories as proper eating habits, preventive behaviors and health practices, compared to respondents with secondary education. Soldiers residing in cities had statistically significantly higher health behaviors intensities in all categories, compared to village residents. A significantly higher score in all health categories was noted in soldiers with normal body weight compared to those with diagnosed obesity. There was no significant relationship between the age of the respondents and health behaviors. Conclusions: The study found that factors such as type of armed forces, BMI, place of residence and education level were significant for the adoption of health behaviors by PAF. The level of health practices was significantly higher among AF soldiers compared to other types of armed forces. It seems necessary to further disseminate education on pro-health behaviors, especially among soldiers with obesity through participation in organized training and psychodietetic consultations as part of the National Health Programme.
