Opis:
This work is a direct continuation of previous works of authors ([Binderman, Borkowski, Szczesny 2008, Binderman, Szczesny 2009]). The goal of this work is to generalize known methods of constructing measures of synthetic objects, methods that use radar charts of vectors. The methods listed in this work factor in weights assigned to features and make the values of indicators independent from the ordering of considered features. The listed methods have been applied in the analysis of regional differentiation of agriculture in Poland between 2001 and 2010.

Opis:
The measure of observation depth in multidimensional samples, introduced into statistical practice by Tukey, has become a new tool for data analysis. It is a proposed method for determining multi-dimensional positional statistics, particularly in the analysis of non-typical data with outstanding observations. Applying a rule of depth helps to overcome the difficulties associated with sorting multidimensional observations. The notion of data depth has been intensively developed by many scholars, and, consequently, various criteria of the measurement of observation depth in a multidimensional samples may be found in literature. This paper contains a comparison of selected criteria of the measurement of observation depth in a two-dimensional case.

Opis:
This scientific article researches the procedure for issuing a European protection order by a Polish court or public prosecutor, resulting in the enforcement of protective, penal, or probation measures by a competent judicial or equivalent authority in a Member State of the European Union. These measures require refraining from staying in certain environments or places and avoiding contact with or proximity to certain people. This article does not cover provisions concerning the execution of such an order by the competent authority of a Member State. The main research objective is to demonstrate the importance of this measure in continuing the protection of the aggrieved in another Member State. The research findings are original and primarily national in scope but also relevant to other countries due to their relation to an EU instrument. This article analyses the essence of the European protection order, its issuance requirements, including the ruling on the aggrieved’s protection measure, necessity of issuing the order, aggrieved’s motion, issuance proceedings, authorised issuing authorities, ruling form, forum for issuance, issuance mode, right to appeal, order transmission, and information obligations. The paper is significant for its in-depth dogmatic analysis and substantial theoretical content and is practical in guiding interpretation of the requirements for the application of this measure and the issuance procedure.

Opis:
Construction of confidence regions for multi-dimensional samples is usually performed with a known stochastic distribution of a random vector in question. However, for multidimensional studies of socio-economic phenomena, such an assumption is difficult to make. Bootstrap methods can be helpful. The main problem with its application is the aligning of respective vectors. To this end, depth measures are used which express the vector distance from the central vector system cluster. Among many such depth measures, the Mahalanobis measure is one of the easiest from a numerical point of view. This paper presents a bootstrap region creation algorithm. It was illustrated for a two-dimensional sample.

Opis:
This paper discusses selected issues of juvenile delinquency proceedings. It points the reader’s attention to the difference in the approach towards a juvenile offender. This different approach consists in shaping the way the state reacts to them breaking a legal norm and directing it towards resocializing education. It underlines the specific characteristics of the interactions’ subject – a juvenile whose identity and social attitudes are in the making. These features justify the fact that educational and reformatory measures based on the law on juvenile delinquency proceedings are applied in their case, rather than the punitive ones defined in the Penal Code. The paper analyses selected topics related to executing specific (educational or reformatory) measures that spark controversy among the entities that take up educational, activating and aid-related actions.

Let G be a group of homeomorphisms of a nondiscrete, locally compact, σ-compact topological space X and suppose that a Haar measure on X exists: a regular Borel measure μ, positive on nonempty open sets, finite on compact sets and invariant under the homeomorphisms from G. Under some mild assumptions on G and X we prove that the measure completion of μ is the unique, up to a constant factor, nonzero, σ-finite, G-invariant measure defined on its domain iff μ is ergodic and the G-orbits of all points of X are uncountable. In particular, this is true if either G is a locally compact, σ-compact topological group acting continuously on X, or the space X is uniform and nonseparable, and G consists of uniformly equicontinuous unimorphisms of X.

The tool we use for determining these candidates is the Expectation-Maximization algorithm, whose goal is to optimize the likelihood for the given data points, i.e. the known Mahler measures up to degree 44, to be generated by a specific mixture of Gaussians. We will give the mean (which is a candidate to be a new limit point) and the relative amplitude of each component of the more likely gaussian mixture.

Results of this type lead to the Liouville equation and have been frequently proved under various assumptions. Our method of the proof is simpler and more direct.

Opis:
In this paper, we combine two alternative procedures for decomposing the Gini index: the Silber matrix approach and the Dagum technique based on Gini mean difference. This combined decomposition can be used for overlapping as well as no overlapping population subgroups. The presented decomposition procedure derives the within-group, the between-group, and the overlapping inequalities by exploiting all of the information on income distribution contained in one matrix accounting for pair wise disparities between per capita income shares. Moreover, this matrix approach can serve the scope of counting the frequency of overlapping, providing new insights for a more complete analysis of overlapping. The suggested methodology is applied to survey data on Italian employee incomes in 2000 and 2008.

Opis:
The main purpose of this paper is to find the most effective method for the normalization of a final set of diagnostic variables for indirect consumption research with the use of synthetic consumption measures. The chosen normalization methods (standardization, unitarization and ratio transformation) were analyzed, both in the classical and the order approaches, with the use of different methods for multidimensional median vector construction (border and Weber median). Implementation of the multidimensional median construction is very important in the case of research objects with atypical characteristics of diagnostic variables (a separate analysis of Warsaw from the Mazowieckie Voivodeship). This kind of research units can cause asymmetry in empirical distribution of diagnostic variables which has a significant impact on the result of the linear order set of research objects. Additionally, implementation of the Weber median allows for considering the interactions in a set of diagnostic variables, which is crucial from the point of view of economic analysis.

Opis:
The paper addresses the problem of measuring the efficiency of civil jurisdiction courts. Non-parametric data envelopment analysis (DEA) has been proposed as a measurement instrument. Hearing (settling) a case within a reasonable time, as seen from the perspective of a citizen, is defined to be a positive output (result) of a court action. The production factors considered include human resources directly related to legal processes. The analysis was carried out for the 26 Cracow district courts. The goal has been assumed to be achieving the best possible outputs, without increasing resources. The results obtained prove that there exist reserves within these organizations that would allow them to shorten the queue of pending cases. The proposed method of measuring efficiency may constitute a starting point for further work on trying to create measurable standards of the functioning of the judiciary in Poland.

The value added by the authors is the construction of measures for conformability of structures of two objects. Those measures may also be used to define similarities between given objects. Proposed measures are independent of the order of features.

The process utilises the idea of Gini index based on a Lorenz curve as well as a method presented by the authors in [Binderman, Borkowski, Szczesny 2010]. The presented technique can also be used by analysts to create new coefficients of concentration based on measures of similarity and dissimilarity of objects so that from the set of constructed coefficients one that best fulfils the required criteria of sensitivity can be chosen.

Podstawą przyjaźni w teraźniejszości jest szacunek i porozumienie, prowadzące do tworzenia wspólnoty. Warunkiem poszukiwania wspólnoty jest dążenie do równoważności osób, słów, czynów. Tworzy ono odpowiedzialność wzajemną dzięki woli odnajdowania wspólnej miary w traktowaniu świata zewnętrznego wobec poszukujących. W ten sposób odpowiedzialność stwarza możliwość zaistnienia wzajemności. Wspólnota tak powstająca jest zaprzeczeniem wzajemności konwenansowej, opartej o aktualny w społeczeństwie (zbiorowości) „idol rynku”. Wymaga ona ćwiczeń w równowartości aktów wzajemnych.
Friendship is the foremost form of human individual relation, a demanding community of ethical courage and reciprocation of the measure of life in the ethico-existential dimension. The said relation is of autotelic nature, being no substitute for other forms of human co-existence, however it contributes to solving issues insurmountable in other forms of human relations. It opens up the human’s existence to wider dimensions of co-existence and cofeeling. In the human community a man’s development – of an individual and that of a member of the society – is determined by their gradual realization of stable humanistic values, constituting the fundamental criterion of their attitude towards reality. The human closeness and reciprocating the measure of life are the basic features of friendship and community. That makes those qualities compatible both existentially and practically. The abovementioned forms of human existence have to be clearly distinguished from the passing conventional reciprocity, founded on the societally-accepted concept of “the idol of the market”. The relevance of the will to authenticity of the co-existing human beings, finding its expression in practicing equivalency in acts of reciprocity and shaping a mutually adequate measure of life, has to be strongly emphasized.

The purpose of this article is to present the possibilities of measuring the efficiency of processes in public administration offices in the context of quality management systems which operate in them and which are conformable to the requirements of BS EN ISO 9001:2009. The first part of the paper presents the results of the analysis of the possibility of measuring the effectiveness and efficiency of processes. Next, the article describes the results of the diagnosis implementation of measurement processes studied in marshal offices, for the analysis of these processes effectiveness. The study involved three selected marshals’ offices having implemented a quality management system complied with the requirements of ISO 9001. In these units a self-assessment based on the guidelines of ISO 9004, unstructured interviews with proxies for the quality management system and in-depth documentation studies were conducted. Studies showed an insufficient preparation of these units to measure the effectiveness of processes, including the implementation processes of administrative services. In the final part taxonomic meters are proposed to measure the effectiveness of processes .

If there exist a Borel measure µ with supp µ ⊂ Γ and constants $c_{1} > 0$ and $c_{2} > 0$ such that $c_{1}r^{d} ≤ µ (B(x,r)) ≤ c_{2}r^{d}$ for all 0 < r < 1 and all x ∈ Γ, where B(x,r) is a ball with centre x and radius r, then Γ is called a d-set. The second aim of the paper is to provide a link between the related Lebesgue spaces $L_{p}(Γ)$, 0 < p ≤ ∞, with respect to that measure µ on the hand and the Fourier analytically defined Besov spaces $B^s_{p,q}(ℝ^n)$ (s ∈ ℝ, 0 < p ≤ ∞, 0 < q ≤ ∞) on the other hand.

Opis:
The purpose of the study (presented in this article) was to develop a measure of resilience to crisis, one that may be applied to regional data. In principle, such measure can take either positive or negative values. A positive value confirms resilience to crisis, whereas a negative one confirms the absence of resilience (sensitivity/vulnerability). The measure uses growth rates referred to the previous year under the assumption that crisis results in a slowdown in growth, or even in a decline in values of important economic indicators. Growth rates are standardized by dividing values of original change rates by medians specified based on spatio-temporal data modules. Such division results in each characteristic being brought to equal validity. Simultaneously, the original character is maintained and variables are not “flattened” by the outliers. Changing destimulants into stimulants occurs during growth rates calculation. The measure of resilience to crisis is calculated as an arithmetic mean of the values of characteristics brought to comparability. The measure of resilience can be converted into the measure of sensitivity by multiplying it by (-1). The application of the proposed measure to assessing the resilience to crisis in the period 2006-2011 is presented for regions meant as the European Union NUTS2 units. The measure is based on comparable data, which allowed for using only six variables measuring changes in GDP, salaries, investments, household income, employment and unemployment.

Introduction and aim. The period immediately after leaving the hospital is known as the transition home, which presents a critical time for parents to take on all the responsibilities and care of a child without the support of the hospital environment. The purpose of this study is to culturally adapt the Pediatric Transition Experience Measure (P-TEM) instrument into Turkish and test its validity and reliability. Material and methods. We conducted this methodological study with parents of children who were discharged from the hospital between May 2021 and May 2022. We evaluated linguistic, content, construct, convergent validity, and internal consistency. Results. The P-TEM exhibited a two-factor structure and accounted for 65% of the overall variability. The internal consistency reliability for the transition preparation and transition support subdimensions was 0.779 and 0.793, respectively, while the total measure had a reliability of 0.831. The item-total correlations for the P-TEM ranged from 0.493 to 0.671. Parents who received the highest P-TEM scores experienced a 5.1-point improvement (95% confidence interval: 1.7 to 8.6) in their satisfaction with healthcare services, which was greater than that of parents who reported lower P-TEM scores. Conclusion. It is worth noting that the P-TEM has been validated and has high reliability in Türkiye.

Relevance of this research lies in the development of an urban environment typology from the subjectivity point of view. This theme is considered in systemic integrity (human – society – humanity - biological species), which allows to identify the nature of the aesthetic measures. Subsequently, the following generalized types of environment are distinguished: naturecentric, anthropocentric, sociocentric and integrated. As a result, the research identifies the main tasks and key issues of reconstruction and humanization of the environment.

Opis:
Multidimensional analysis uses various measures for assessing economic effects. However, no single synthetic measure, regardless how popular, can give a satisfactory solution to the above problem. In general, various approaches of combining measures can lead to stable outcomes. Nevertheless, when combining "weak" classifiers one can obtain inevitably poorer classification. We propose here a new approach to construct doubly synthetic measures. The main goal of this work is to analyse the influence these new synthetic measures on the ranking of multidimensional objects.

Opis:
Let X be a complete metric space, and S the union of a finite number of strict contractions on it. If P is a probability distribution on the maps, and K is the fractal determined by S, there is a unique Borel probability measure $ \mu_P$ on X which is invariant under the associated Markov operator, and its support is K. The Open Set Condition (OSC) requires that a non-empty, subinvariant, bounded open set $ V \subset X$ exists whose images under the maps are disjoint; it is strong if $ K \cup V \ne 0 $.In that case, the core of $ V, \check{V} = \bigcap_{n=0}^\infty $ is non-empty and dense in K. Moreover, when X is separable, $\check{V}$ has full $\mu_p$-measure for every P. We show that the strong condition holds for V satisfying the OSC iff $\mu_P(\delta V) = 0 $, and we prove a zero-one law for it. We characterize the complement of V relative to K, and we establish that the values taken by invariant measures on cylinder sets defined by K, or by the closure of V, form multiplicative cascades.

Measures of inequality, properly adapted, often tend to be used as a tool to address the issue of disproportionality. The most popular of them, such as the Gini or Atkinson coefficient, or entropy coefficient can, under certain circumstances, act as measures of disproportionality. However, one must specify precisely what is to be measured and interpret the results consistently. In this paper we analyze what confusion or outright errors can be committed when using inequality coefficients. The presented analysis is aimed at the Gini coefficient, however, the problem also applies to the rest of the coefficients.

In other words, the purpose of the paper is studying which of the above func- tions fulfill the additional axiom of measure of risk, which can enrich Arzner’s and other axioms. This axiom is not a consequence of Arzner’s and other axioms. Furthermore, the author researches mathematically if the mentioned functions of risk retain their properties after replacing the partial order with the stochastic order. Finally the author presents the new measure of risk which fulfills all the axioms of measure of risk and the additional axiom.

Opis:
A novel method for calculation of the entropy measure in wavelet space is proposed. This perceived-based entropy measure uses a Second Order Model entropy estimator, in which the occurrence of neighbors is considered in formulation. It has the intention to allow the implementation of a more suitable measure in coding processes and a relationship between the metric and the description of perceptual features. This method is used for the Rate-Distortion optimization in order to improve the bit-allocation coding algorithm, demonstrating that the wavelet-based entropy estimates a truncation step close to the target rate. The hypothesis is founded in the effect of distortion on the coefficient allocation. Because entropy measure is a close approximation of the conditional probability of image in multiresolution space, it provides an adequate representation for the information of a Detail feature. A definition of Detail-based homogeneity variance criteria is used for the information quantity - wavelet representation space, in order to find the image that fits a given Quality Level criteria. Experimental results are obtained for artificial and natural databases.

Opis:
The objective of the article was to re-define the bipolar metropolitan area within the area of the Kujawsko-Pomorskie region (NUTS 2). Concentration of metropolitan features, as well as socio-economic situations of its communes (NUTS 5) in 2011, and also the dynamics of communes’ development in the period 2009-2011 were considered in the procedure of delimitation. Bydgoszcz and Toruń, as the economically strongest cities in the region, were established as the dual core of the bipolar metropolitan area. It was assumed that the determined metropolitan area would cover the best developed and the fastest developing communes which met the following criteria of a metropolitan area: neighbourhood, continuity, compactness, maximum distance and population. The development levels of the communes were determined with the use of syn-thetic measure. Its values were calculated considering the economic (e.g. the amount of income) and also social (e.g. unemployment) aspects of regional devel-opment, as well as features typical of metropolitan areas, such as: well-developed sectors of R&D, knowledge-based economy and serving superior services. In the research, linear arrangement methods classifying as taxonomic tools of multivari-ate data analysis was applied. The metropolitan area resulting from the research (BipOM) slightly differs from the Bydgoszcz-Toruń Metropolitan Area (B-TOM) which was formally ap-pointed in 2005 and composed all of the communes located within the area of the Bydgoski and Toruński districts (NUTS 4). Chełmża and Koronowo, as the less developed communes of the districts, were excluded from the new metropolitan area, while the communes of Ciechocinek, Nakło and Unisław, belonging to the neighbouring districts of the region, were included in the BipOM due to their significant level of regional development and its dynamics. Furthermore the Inowrocław district (bordered on the BipOM) was identified as the prospective candidate for the BipOM, due to the fact that its communes demonstrate a high potential for regional development.

Opis:
This paper presents the Polish version of the Multiple Stimulus Types Ambiguity Tolerance Scale (MSTAT-II) developed by D. L. McLain: a short 13-item measure of an individual’s orientation, ranging from aversion to attraction, toward stimuli that are complex, unfamiliar, and insoluble. The aim of the study was to determine the validity and reliability of the scale. The participants in the study were 303 first-year students, aged 17 to 24: 234 women and 69 men. The authors chose this kind of sample because the significance of ambiguity tolerance should be particularly high in the case of the individual’s adaptation to the demands of a new and complex situation, such as the beginning of studies. Confirmatory factor analysis confirmed the hypothesized one-factor structure of the model of ambiguity tolerance. The study also revealed a moderate positive relationship between MSTAT-II/PL scores and scores on the Tolerance for Ambiguity Scale (TAS) by Herman and colleagues, measuring ambiguity tolerance; MSTAT-II/PL scores were positively related to extraversion, openness to experience, conscientiousness, positive affect, and satisfaction with life, as well as negatively related to neuroticism and negative affect. The results obtained support the use of the Polish version of the Multiple Stimulus Types Ambiguity Tolerance Scale as a reliable (Cronbach’s α = .85) and valid measure of ambiguity tolerance.

Opis:
The aim of this article is to present the theoretical background and internal structure of the Polish adaptation of the Religious Comfort and Strain Scale (RCSS) by Yali, Exline, Wood, and Worthington. Exploratory Factor Analysis showed that the Polish adaptation of RCSS has four factors: it consists of a one-dimensional Religious Comfort subscale and three subscales regarding religious strain: (1) Negative emotions toward God, (2) Fear-Guilt and (3) Negative social interactions surrounding religion. The scale’s reliability and construct validity are satisfactory. Although further research is needed, it may be assumed that this tool can be used successfully in research on the functional aspects of religion.

Opis:
Within the EU cohesion policy, better and worse developed regions are subcategorised, taking account of the GDP value per capita. Based on that, areas qualifying for obtaining support from aid programs from the EU budget are established. The purpose of the article is an attempt at specifying the co-dependencies between the EU fund absorption and the changes in the level of the socio-economic development in the regional dimension. The research was conducted at the level of 73 NUTS-3 units in Poland in three stages. At the first one, the level of the development of the subregions in Poland is exhibited, subcategorising the factors of that development: human capital, material capital, natural environment as well as entrepreneurship and innovativeness. At the second stage, variation in the EU fund absorption in the researched units is presented. At the third stage, interdependencies between the extent of the absorption and the changes in the level of development within the arrangement of the factors of that development are taken up.

Opis:
Statistical analyses in economics are often based on explaining the phenomena by comparing time series. The purpose of such types of analyses is to find out the similarity and schematic behavior of phenomena which appear in the data. Usual time series are compared with the use of a different similarity measure which, in accordance with the literature, could be divided into four categories. In this article, I propose a method that allows to indicate whether two time series are generated by the same stochastic processes. For this purpose, I analyze a method based on a permutation test. The idea of this test is much simpler than the tests based on theoretical distributions. I also conducted a simulation analysis based on the data generated according to different scenarios, subsequently comparing the results of that analysis.

This study developed a tool for measuring adverse health effects in students who use digital textbooks. The study tool was aimed at 690 sixth-graders who had used digital textbooks for more than a year in schools taking part in the nationwide digital textbook pilot program. We determined the validity and reliability of the tool. The tool for measuring adverse health effects of digital textbooks consisted of a total of 22 items, including 13 on physical symptoms and 10 on psychological symptoms. For the physical symptoms, two factors – whole body/musculoskeletal symptoms and eye symptoms – were extracted. For the psychological symptoms, the two assessed factors included negative and positive psychological symptoms. This tool will not only be helpful in preventing and managing adverse health effects of digital textbook use by identifying various physical and psychological symptoms, but will also be useful as a basis for the expansion of digital textbooks.

The paper presents the results of the research over the measurement of the progress in the realization of the objectives specified in “Europe 2020 - a strategy for smart, sustainable and inclusive growth” in 2016 in comparison with 2010. The analysis availed itself of the statistical data of Eurostat which describes the main indicators of the strategy for all member states of the European Union. The available empirical data allowed for constructing a synthetic measure reflecting the progress in realizing the objectives specified in the Strategy. The analysis of the values that the said measure assumed became a basis for creating a rating of EU member states for two distinct years that were subject to scrutiny. Also, there was specified the variation in the value of the said measure and the changes in the positions occupied by particular states in the mentioned rating. What was also conducted was a cluster analysis, which allowed for dividing the scrutinized countries into groups in case they are described by more than one property. Except for this and as compared to all the previous works on the subject, the method of the construction of the synthetic measure was considerably sharpened.

Opis:
Automatically controlled hydraulic tension systems adjust the tension force of a conveyor belt under different working conditions. Failures of an automatically controlled hydraulic tension system influence the performance of conveyor belts. At present, the maintenance of automatically controlled hydraulic tension systems mainly considers the replacement of components when failures occur. Considering the maintenance cost and downtime, it is impossible to repair all the failed components to improve the hydraulic tension system. One of the key problems is selecting the most valuable components for preventive maintenance. In this paper, preventive maintenance for multiple components in a hydraulic tension system is analyzed. An index is proposed to select more reliable preventive maintenance components to replace the original ones. A case study is given to demonstrate the proposed method. When the cost budget increases, there are three different variations in the number of components for selective preventive maintenance (SPM).

Purpose – The purpose of the article is to rate the diversity of the financial situation of municipalities in Świętokrzyskie voivodship in relation to their financial independence. Research method – The financial situation and independence are multidimensional. They are shaped by, among others, economic, legal and financial factors. The assessment of the financial standing and independence was based on the value of the synthetic measure determined by the TOPSIS method. The study covered the years 2009-2018. The article uses data obtained from the Regional Accounting Chamber of Kielce. Results – The subject of the discussion presented in the article are the issues of the financial situation and independence of the municipalities (102) of Świętokrzyskie voivodship. As part of the research, a set of diagnostic variables was selected, their nature, synthetic measure, and their division into quartile groups were determined. Originality / value – Stability and certainty of income determine the scope and level of tasks performed by the municipalities. The financial situation and independence of municipalities are not a permanent category. The financial situation of the municipalities in Świętokrzyskie voivodship was shaped by the development potential, the level of financing public services and implemented transfers, income and expenses independence and budget solvency. The best municipalities were characterized by a good situation and a high level of financial independence.

Opis:
Artykuł ma charakter naukowo-badawczy, a jego przedmiotem jest wydanie europejskiego nakazu ochrony przez polski sąd lub polskiego prokuratora, obejmującego wykonanie przez właściwy sąd lub inny organ państwa członkowskiego Unii Europejskiej środka zapobiegawczego, karnego i probacyjnego w zakresie powstrzymywania się od przebywania w określonych środowiskach lub miejscach, kontaktowania się z określonymi osobami lub zbliżania się do określonych osób. Pominięta została regulacja wykonania takiego nakazu przez właściwy organ państwa członkowskiego. Celem głównych tez badawczych było wykazanie, że środek ten spełnia istotną rolę, umożliwiając kontynuowanie ochrony pokrzywdzonego w innym państwie członkowskim. Wyniki badania mają oryginalny charakter. Mają one przede wszystkim zasięg krajowy, ale mogą być przydatne również w innych państwach ze względu na to, że dotyczą instrumentu unijnego. Analizie zostały poddane: istota europejskiego nakazu ochrony, przesłanki jego wydania, w tym orzeczenie środka ochrony pokrzywdzonego, niezbędność wydania europejskiego nakazu dla ochrony praw pokrzywdzonego, wniosek pokrzywdzonego, postępowanie w przedmiocie wydania europejskiego nakazu ochrony, w szczególności organy uprawnione do jego wydania, forma orzeczenia, forum jego wydania, tryb wydania, zaskarżalność, przekazanie europejskiego nakazu oraz obowiązki informacyjne. Opracowanie ma istotne znaczenie dla nauki, gdyż zawiera pogłębioną analizę dogmatyczną i duży ładunek myśli teoretycznej, a także dla praktyki, wskazuje bowiem kierunki interpretacji przesłanek stosowania tego środka oraz postępowania w przedmiocie jego wydania.
The article is of scientific nature and undertakes research into the procedure of issuance of the European protection order by a Polish court or a public prosecutor, resulting in the execution of a protective, penal or probation measure by a competent judicial or equivalent authority in a Member State of the European Union, which requires refraining from staying in certain environments or places, and contacting or approaching certain people. The regulation concerning the execution of such an order by the competent authority of a Member State has been omitted herein. The aim of the main research theses is to show that this measure plays an important role as makes it possible to continue the protection of the aggrieved in another Member State. The research findings are original in character. They have primarily national range but can also be useful in other countries due to the fact that they relate to the EU instrument. The article analyses the essence of the European protection order, the requirements for its issuance, including the ruling on the measure of protection of the aggrieved, the necessity of the issuance of the European protection order to protect the rights of the aggrieved, the motion of the aggrieved, the European protection order issuance proceeding, in particular the authorities authorised to issue it, the form of the ruling, the forum for its issuance, the issuance mode, entitlement to appeal, the transmission of the European protection order, and information obligations. The paper is important for science because it contains an in-depth dogmatic analysis and a large load of theoretical thought, as well as for practice, as it indicates the direction of interpretation of the requirements for the application of this measure and the issuance procedure.

Opis:
According to literature, herding can be observed not only within single stock market, but also on international level. Poland has entrance to Euro Zone in perspective, so especially interesting is answer to the question whether herding is present on the stock markets of candidate countries to Euro Zone? Moreover, whether this tendency will be more noticeable in periods of higher volatility than during the periods of relative market stability, as suggested by psychological theories. To find the measure of herd tendency we can refer both to neoclassical and behavioral theories. Basing on models grounded in rationality assumption, there is a need to assume informative efficiency of markets. Thus, it can be expected that aggregated changes in stock markets should be reflected in the process of prices formation. Behavioral literature pointed that if tendency of herding is present on international level, it can be assumed that markets ‘in average’ will behave in the similar way. Following this idea the size of deviation of the given series from the ‘average’ can be taken as the measure of herding activity in aggregated market. Methodology created by Christie, Huang and Chang, Cheng, Khoran will be used as a starting point for the consideration of this problem. To propose more perfect measure of herding, in the paper this approach will be developed by using alternative methodology for average and measure of deviations construction. Those improvements will cause that, theoretical models will come closer to reality and will take into account both sociological and behavioral tendencies present in investors activity.

A boundary point of this set is shown to be extreme (and even exposed) if its support inside the open unit disk consists of two points that do not lie on the same radius of the disk. If its support inside the unit disk consists of 3 or more points, it is very seldom an extreme point. We also give a necessary condition for extreme points to be exposed and show that so-called BSZ-measures are never exposed.

Opis:
The paper deals with the experimental verification of a model of the fatigue loading nonproportionality. The assumption of the proposed model is that the loading nonproportionality degree depends on: (a) modules of vectors of rotating stresses, (b) angular distances of these stres s vectors measured in relation to the critical pIane. The performed experiment involved modeling of the nonproportional fatigue loading through programmed changes of principal axes positions. Different positions of the principal axes were obtained by using two loading blocks: fully reversed torsion and complex loading, that is to say, tension-compression and torsion. During the tests, the influence of the range of the orientation angle of principle axes on fatigue life was examined. The obtained results allowed one to confirm the thesis that the nonproportionality degree depends also on the angular distance in which the stress vector acts in relation to the critical pIane.
W artykule przedstawiono weryfikację eksperymentalną modelu nieproporcjonalności obciążenia zmęczeniowego, który był podstawą sformułowanych przez autora wieloosiowych kryteriów zmęczeniowych. W modelu tym zakłada się, że w warunkach obciążeń nieproporcjonalnych można wyróżnić płaszczyznę krytyczną. Jednocześnie, obrót osi głównych powodować może intensyfikację procesu kumulacji uszkodzeń zmęczeniowych. Decyduje o tym stopień nieproporcjonalności obciążenia. W przyjętym modelu założono, że o stopniu nieproporcjonalności obciążenia decydują: (a) moduły wektorów obracających się naprężeń, (b) kątowe odległości wektorów tych naprężeń mierzone w stosunku do płaszczyzny krytycznej. Zrealizowany eksperyment polegał na modelowaniu zmęczeniowego obciążenia nieproporcjonalnego poprzez programowane zmiany położenia osi głównych. Różne położenia osi głównych uzyskiwano realizując dwu blokowy program obciążeń: wahadłowego skręcania i obciążenia złożonego, w tym przypadku rozciągania ze skręcaniem. Badano wpływ zmian położenia osi głównych w trakcie próby uzyskiwaną na trwałość zmęczeniową. Otrzymane wyniki dają podstawę do przyjęcia tezy, że stopień nieproporcjonalności zależy nie tylko od modułów obracających się naprężeń, ale jest zależny także od odległości kątowej, w jakiej wektor naprężenia działa w stosunku do płaszczyzny krytycznej.

Opis:
The objective of the paper is to assess the situation of Polish regions (NUTS 2) and their progress in sustainable development regarding social inclusion. The study covers the period after Poland’s accession to the European Union (2004-2011). The implementation of ratio analysis and synthetic measure facilitated an evaluation of occurring tendencies. Taxonomic analysis was performed for the years 2006 and 2011. Linear arrangement methods and a common development pattern were applied in constructing the measure. The observed tendencies may be assessed as positive. All regions made progress towards the pattern even though the rate of occurring transformations was diversified. At the same time territorial disparities became smaller. Despite the recorded progress the situation in the country still requires to be improved. Among the most significant challenges encountered by Polish regions there are extensive income distribution inequalities, long-term unemployment, high percentage of population threatened with poverty and low participation of the disabled in the labour market.

Opis:
This paper is dedicated to analysing the size of local administration. On the basis of literature study, ten variables that define size of local administration were chosen, out of these variables two synthetic measures were created. The sizes of local administration at the level of voivodships were calculated for 2013. The research results show a big differentiation among the analysed units in Poland. Data were sourced from the Polish Main Statistical Office (GUS). Taxonomic methods were used in the analysis – synthetic measures were constructed on the basis of the Hellwig method.

The purpose of the article is to check if companies should be assessed on the base of dynamics of the financial ratios or both dynamics of financial ratios and nominal values of financial ratios. In order to point out the better portfolio their performances are compared. Companies are chosen to quantile portfolios due to their position in the ranking that is constructed on the base of the chosen financial ratios (nominal values and/or their dynamics). As a result, it can be stated that the best portfolios are two portfolios pointed out by the ranking constructed on the base of nominal value of financial ratios and their dynamics.

Opis:
A extensive body of literature is devoted to the production of mobility measures based on transition matrices. The applications often involve panel data, and yet the impact of demographic events on enterprise mobility is not considered. The article aims provide a definition of enterprise mobility, in terms of the capability to create or liquidate jobs. Moreover, some existing mobility measures are modified so that they also take into account newborn and exiting firms. The proposed index has all the relevant basic properties which make it a rigorous descriptive statistics. The mobility of Italian capital-owned enterprises in the years 2010 2017 is analysed in the case study. What we propose may be an alternative tool for practitioners to measure the degree of mobility in the presence of demographic events. It may be considered an initial step in future research regarding its different applications (e.g. labour market flows or movements among income classes), also considering more complex theoretical backgrounds.

The construction is important in a market economy. From the development of the construction industry depends on large extent how the economy will function. In Poland the share of construction in GDP is about 8 percent. Hence, the need for continuous monitoring of both –the market and the use of methods– that will objectively evaluate the quality of the construction companies. For this type of methods may include taxonomic measures. In the present study uses a synthetic taxonomic measure attractiveness of investment (TMAI) to compare the condition of 30 selected large construction companies listed on the Warsaw Stock Exchange. The researches were done for 2008–2012 years.

Opis:
Every characteristic function φ can be written in the following way:
φ(ξ) = 1/(h(ξ) + 1), where h(ξ) =
⎧ 1/φ(ξ) - 1 if φ(ξ) ≠ 0

⎩ ∞ if φ(ξ) = 0
This simple remark implies that every characteristic function can be treated as a simple fraction of the function h(ξ). In the paper, we consider a class C(φ) of all characteristic functions of the form $φ_{a}(ξ) = [a/(h(ξ) + a)]$, where φ(ξ) is a fixed characteristic function. Using the well known theorem on simple fraction decomposition of rational functions we obtain that convolutions of measures $μ_{a}$ with $μ̂_{a}(ξ) = φ_{a}(ξ)$ are linear combinations of powers of such measures. This can simplify calculations. It is interesting that this simplification uses signed measures since coefficients of linear combinations can be negative numbers. All the results of this paper except Proposition 1 remain true if we replace probability measures with complex valued measures with finite variation, and replace the characteristic function with Fourier transform.

Opis:
Problematyką niniejszego opracowania jest ustalenie, czy w obowiązującym stanie prawnym istnieje potrzeba penalizacji zachowania polegającego na uchylaniu się od wykonania orzeczonego przez sąd środka kompensacyjnego, nałożonego na podstawie art. 46 § 1 k.k. W przypadku odpowiedzi pozytywnej na powyższe pytanie należy rozważyć, czy zachodzi potrzeba wprowadzenia regulacji w celu jej zapełnienia, ocenić zaproponowane zmiany i sformułować propozycje de lege ferenda. Bazę dla niniejszych dywagacji stanowić będzie ustawa z dnia 13 czerwca 2019 r. o zmianie ustawy – Kodeks karny oraz niektórych innych ustaw oraz projekt ustawy o zmianie ustawy – Kodeks karny oraz niektórych innych ustaw z dnia 14 maja 2019 r. wraz z uzasadnieniem, a także materiały legislacyjne i opinie środowiska naukowego na temat proponowanych regulacji.
The problem of this study is to determine whether in the current legal state there is a need to criminalise behaviour consisting in evading execution of a compensation measure ordered by a court and imposed on the basis of Article 46(1) of the Penal Code. In the case of a positive answer to the above question, it should be considered whether there is a need to introduce a regulation to fill it, to assess the proposed changes and to formulate de lege ferenda proposals. The basis for the present deliberations will be the Act of 13 June 2019 on amending the Act, the Penal Code and some other acts and the draft Act of 14 May 2019 on amending the Act – Penal Code and some other acts together with the justification, as well as legislative materials and opinions of the scientific community on the proposed regulations.

W pracy przedstawiono koncepcje budowy wskaźników przeznaczonych do porządkowania obiektów opisanych wieloma cechami o wartościach nieujemnych na tej samej skali, czyli takich, których wartości można interpretować jako składowe struktury. Podane mierniki mogą być wykorzystywane do cyklicznego raportowania w systemach MIS (Management Information System) w systemach informacyjnych zarówno instytucji publicznych obserwujących zmiany strukturalne, jak i w dużych korporacjach o rozbudowanej strukturze wewnętrznej. Koncepcję zilustrowano na przykładzie zmian, jakie zachodzą w strukturze obszarowej gospodarstw w Polsce na tle nowych państw Unii Europejskiej w okresie 2003 -2010.
The paper presents the concepts of indicators intended to organize objects described by many features of non-negative values on the same scale, i.e. ones whose values can be interpreted as components of a structure. The discussed measures can be used in information systems of both public institutions which observe structural changes and large corporations with extensive internal structures for reporting in Management Information Systems (MIS). The concept is illustrated by the changes that occur in the structure of farms in Poland against the background of the new EU Member States in the period 2003-2010.

The economic distance defines a dissimilarity level between objects functioning in the economic space. It is one of the most important issues of spatial econometrics. However its measurement is difficult due to the definition, description and estimation problems. The objective of the paper is to indicate the role of symbolic data in describing the economic distance and also the way of its measurement using symbolic data analysis methods. A significance of the economic distance, measurement problems, symbolic data concept and dissimilarity measures, and also an empirical example were presented in the paper.

In this paper we describe a new measure of remoteness between sets described by nominal values. The introduced measures of perturbation of one set by another are considered instead of commonly used distance between two sets. The operations of the set theory are operated and the considered measures describe changes of the perturbed second set by adding the first one or vice versa. The values of the measure of sets’ perturbation are range between 0 and 1, and in general, are not symmetric – it means that the perturbation of one set by another is not the same as the perturbation of the second set by the first one.

In a similar way, estimates of the Gelfand width are provided. As an application we get upper bounds for the entropy of co(T), $T={t_1,t_2,...}$, $||t_j||≤a_j$, by functions of the $a_j$'s only. This partially answers a question raised by K. Ball and A. Pajor (cf. [1]). Our estimates turn out to be optimal in the case of slowly decreasing sequences $(a_j)_{j=1}^∞$.

Opis:
Recently, there has been a growing interest in optimization problems associated with the arbitrage pricing of derivative securities in imperfect markets (in particular, in models with transaction costs). In this paper, we examine the valuation and hedging of European claims in the multiplicative binomial model proposed by Cox, Ross and Rubinstein [5] (the CRR model), in the presence of proportional transaction costs. We focus on the optimality of replication; in particular, we provide sufficient conditions for the optimality of the replicating strategy in the case of long and short positions in European options. This work can be seen as a continuation of studies by Bensaid et al. [2] and Edirisinghe et al. [13]. We put, however, more emphasis on the martingale approach to the claims valuation in the presence of transaction costs, focusing on call and put options. The problem of optimality of replication in the CRR model under proportional transaction costs was recently solved in all generality by Stettner[30].

Opis:
As an international organization the European Union pursues a range of purposes including improvement of public health, prevention of human illness and diseases as well as elimination of the sources of danger to physical and mental health. To enable effective health policies supporting actions of the member states, the data and materials which are fundamental to public health assessments are collected at the Community level. They underpin a variety of analyses necessary to evaluate changes in medical systems and determine the degree of similarity between the EU member states. This article analyses public health in Poland in relation to selected European countries. The study is based on the medical, economic and social indicators available from the EUROSTAT database. The taxonomic methods used in the study allowed ranking the sampled countries and identifying those with the highest level of public health. A more detailed assessment was based on the general presentation of health care systems in each country. In addition to Poland, the other post-socialist countries in the sample are Bulgaria, Estonia, Lithuania, Romania, Slovenia, Hungary and the Czech Republic. Importantly, the study covers the years 2004-2009, after most of the countries joined the European Union. The reason why other former Eastern bloc countries were omitted from the study was the unavailability of appropriate data in the EUROSTAT database. The paper discusses a group of developed European countries too. However, because the complicated historical past of the post-socialist countries and the socio-economic difficulties that result from it make their analysis more interesting from a comparative point of view, they are the primary group explored in this article. This article is divided into theoretical and empirical section. It begins with a short introduction. Part two presents the concept of health and public health. The third part describes key factors differentiating health systems. It briefly presents the main healthcare models, that is: the Bismarck’s, Beveridge’s, Siemaszko’s and the residual model. The fourth section refers to a grouping method based on Hellwig’s taxonomic measure of development. Part five with its scope includes a comparative analysis of public health status of selected European countries. The sixth part presents major determinants of cluster formation. The paper ends with a conclusion that summarizes the obtained results.

Opis:
A new concept of job satisfaction demands an independent measure of two components of job satisfaction (its emotional and cognitive aspects). A classification of techniques for assessing the cognitive aspect of job satisfaction is made and their usefulness for study of different topics is presented. The Satisfaction With Job Scale allows to measure the cognitive aspect of overall job satisfaction. The paper indicates the sources of construction of The Satisfaction With Job Scale. It comprises the technique description, its psychometric properties and validity scores in a heterogeneous group, as well as in four categories of job. The internal reliability of the scale is high – in the heterogeneous group Cronbach’s Alpha is 0,864 (in four groups: 0,814–0,888). The scale has a one-dimensional structure: Factor analysis (principal components) yields one component with eigenvalue exceeding unity which accounted 65,5% of the total variance in the whole group (in four groups: 58,5%–69,8%). The scale shows high convergent validity with other measure of cognitive aspect of job satisfaction and discriminant validity in relation to measures of emotional aspects of job satisfaction and to cognitive aspect of overall life satisfaction. The data show that The Satisfaction with Job Scale is a valuable instrument for measure of overall job satisfaction.

We employ a Hajlasz definition, which uses a pointwise maximal inequality. We prove that these spaces are Banach, that the Poincaré inequality holds, and that the Lipschitz functions are dense. We develop a capacity theory based on these spaces. We study basic properties of capacity and several convergence results. As an application, we prove that each Musielak−Orlicz−Sobolev function has a quasi-continuous representative.

Opis:
The aim of the paper was to assess the regional differentiation of the level of agriculture and its changes over time. Based on the synthetic measure of development the rankings of regions (provinces) were created. The objects were also classified and divided into groups of a similar level of agriculture. In addition, in order to identify the long-term tendency in this sector of economy, the process of -convergence of the level of agriculture has been studied. For the verification of hypotheses dynamic panel models were applied. All computations were performed in the Gretl, based on CSO data.

Opis:
Praca zawiera propozycję oryginalnej metody oceny straty informacji powstałej na skutek zastosowania kontroli ujawniania danych (ang. Statistical Disclosure Control, SDC) dokonywanej podczas przygotowywania danych wynikowych do publikacji i do udostępniania ich zainteresowanym użytkownikom. Narzędzia SDC umożliwiają ochronę danych wrażliwych przed ujawnieniem – tak bezpośrednim, jak i pośrednim. Artykuł koncentruje się na przypadku spseudonimizowanych mikrodanych, czyli wykorzystywanych do badań naukowych danych jednostkowych pozbawionych zasadniczych cech identyfikacyjnych. SDC polega tu zazwyczaj na ukrywaniu, zamienianiu czy zakłócaniu oryginalnych danych. Tego rodzaju ingerencja wiąże się jednak ze stratą pewnych informacji. Stosowane tradycyjnie metody pomiaru owej straty są nierzadko wrażliwe na odmienności wynikające ze skali i zakresu wartości zmiennych oraz nie mogą być zastosowane do danych wyrażonych na skali porządkowej. Wiele z nich słabo uwzględnia też powiązania między zmiennymi, co bywa istotne w różnego rodzaju analizach. Stąd celem artykułu jest przedstawienie propozycji użycia – mającej swe źródło w pracach Zdzisława Hellwiga – metody konstrukcji unormowanego i łatwo interpretowalnego miernika kompleksowego (zwanego także wskaźnikiem syntetycznym) powiązanych cech opartego na wzorcu i antywzorcu rozwojowym w ocenie straty informacji spowodowanej zastosowaniem wybranych technik SDC oraz zbadanie jej praktycznej użyteczności. Miernik został tutaj skonstruowany na podstawie odległości między danymi wyjściowymi a danymi po zastosowaniu SDC z uwzględnieniem skal pomiarowych.
The paper contains a proposal of original method of assessment of information loss resulted from an application of the Statistical Disclosure Control (SDC) conducted during preparation of the resulting data to the publication and disclosure to interested users. The SDC tools enable protection of sensitive data from their disclosure – both direct and indirect. The article focuses on pseudon-imised microdata, i.e. individual data without fundamental identifiers, used for scientific purposes. This control is usually to suppress, swapping or disturbing of original data. However, such intervention is connected with the loss of some information. Optimization of choice of relevant SDC method requires then a minimization of such loss (and risk of disclosure of protected data). Traditionally used methods of measurement of such loss are not rarely sensitive to dissimilarities resulting from scale and scope of values of variables and cannot be used for ordinal data. Many of them weakly take also connections between variables into account, what can be important in various analyses. Hence, this paper is aimed at presentation of a proposal (having the source in papers by Zdzisław Hellwig) concerning use of a method of normalized and easy interpretable complex measure (called also the synthetic indicator) for connected features based on benchmark and anti–benchmark of development to the assessment of information loss resulted from an application of some SDC techniques and at studying its practical utility. The measure is here constructed on the basis of distances between original data and data after application of the SDC taking measurement scales into account.

Opis:
Purpose: The research on the composition of the optimal securities portfolio, conducted for many years, provides new tools and approaches not only to determining the shares of financial instruments in an optimal portfolio but also to the selection of instruments for the portfolio. One of the new approaches is the use of deterministic chaos to determine the composition of the portfolio. The purpose of the paper is to create company rankings and to assess the efficiency of investment portfolios built on their basis. Design/methodology/approach: In order to rank companies in terms of investment attractiveness, and to build and evaluate the efficiency of investment portfolios created on the basis of the division made, the analysis used such measures as: beta coefficient, Hurst exponent, synthetic measures: TMAI and WAI. Findings: The applied measures allowed to rank and divide listed companies due to the level of attractiveness for an investor. The research shows that better results were obtained for portfolios built on the basis of synthetic measures i.e. TMAI than WAI. Research limitations/implications: An important element of portfolio analysis research seems to be the use of tools such as the Hurst exponent. The research showed that the selection of shares for the portfolio based on the Hurst exponent often gives better or as good results as the methods taking into account the economic and financial situation of a company. Practical implications: The application in portfolio analysis. Originality/value: The WAI measures used to create a company ranking and build a portfolio of shares based on it. The application tools of deterministic chaos to determine the composition of the portfolio.

Opis:
In Thailand, droughts are regular natural disasters that happen nearly every year due to several factors such as precipitation deficiency, human activity, and the global warming. Since annual rainfall amount fits an inverse gamma (IG) distribution, we wanted to try testing annual rainfall dispersion via the coefficient of variation (CV). Herein, we propose two statistics for testing the CV of an IG distribution based on the Score and Wald methods. We evaluated their performances by means of the Monte Carlo simulations conducted under several shape parameter values for an IG distribution based on empirical type I error rates and powers of the tests. The simulation results reveal that the Wald-method test statistic performed better than the Score-method one in terms of the attained nominal significance level, and is thus recommended for analysis in similar scenarios. Furthermore, the efficacy of the proposed test statistics was illustrated by applying them to the annual rainfall amounts in Chaiyaphum, Thailand.

This article deals with the problem of spatial interpretation of graphical Foster-Hart formulas. The proposed approach allows the assessment of investments with specific expected payouts. This approach may also be, in a certain sense, considered as generalization in relation to the evaluation, as the author has shown how to interpret certain investment cases. It is also important that in a similar way, one can also evaluate all portfolios, which consist not only of financial instruments, but also other investment assets. The paper presents the idea of the Foster-Hart measurement on the basis of the analysis of a hypothetical action, and all simulation tests were carried out in MATLAB programming environment.

In fact, reliability as the qualities metric is the probability success or the probability that a system or a set of tasks will work without failure for a specified constraints of time and space, as specified in the design and operating conditions specified temperature, humidity, vibration and action. A relatively new methodologies for developing complex software systems engineering is an aspect oriented software systems, that provides the new methods for the separation of concerns multiple module configuration or intervention and automatic integration them with a system. In this paper, a method using fuzzy logic to measure software reliability based on the above aspects is presented. The proposed approach regarding the use of appropriate metrics and low errors in the estimation of reliability has a better performance than other methods.

Opis:
The real world phenomena are often facing the co-existence reality of different formality of uncertainty and thus the probabilistic reliability modeling practices are very doubtful. Under complicated uncertainty environments, hybrid variable modeling is important in reliability and risk analysis, which includes Bayesian distributional theory, random fuzzy distributional theory, as well as fuzzy random distributional theory as special distribution families. In this paper, we define a new hybrid lifetime which is specified by a random lifetime distribution with an uncertain distributed parameter, which is called as random uncertain hybrid lifetime. We furthermore define the average chance distribution as a quality index for quantifying the hybrid lifetime and accordingly the average chance reliability is derived.

Opis:
The present paper is devoted to modelling of a probabi‐ lity measure of logical connectives on a quantum logic via a G‐map, which is a special map on it. We follow the work in which the probability of logical conjunction (AND), dis‐ junction (OR), symmetric difference (XOR) and their nega‐ tions for non‐compatible propositions are studied. Now we study all remaining cases of G‐maps on quantum lo‐ gic, namely a probability measure of projections, of impli‐ cations, and of their negations. We show that unlike clas‐ sical (Boolean) logic, probability measures of projections on a quantum logic are not necessarilly pure projections. We indicate how it is possible to define a probability me‐ asure of implication using a G‐map in the quantum logic, and then we study some properties of this measure which are different from a measure of implication in a Boolean algebra. Finally, we compare the properties of a G‐map with the properties of a probability measure related to logical connectives on a Boolean algebra.

Opis:
The aim of this paper is to present a proposal of two-stage approach for determining dependencies between socio-economic aspects and migration phenomena and also to make an attempt to apply it in the analysis of internal migrations in Poland in 2004-2011. A construction of econometric gravity model using taxonomical measure has been presented. Significance, intensity and impact direction of selected socio-economic aspects on domes voivodeships are much more mobile territorially; a poor situation of a region is an impeding factor of migratory movement. Regional labour market situation constitutes a deciding reason of population inflow, while a standard of living plays a negligible role. Migration scope is relatively slight in Poland, significant population flows take place between neighbouring regions. Economic cycle affects an intensity of domestic population flows. During the period of prosperity the flows seem to be more dispersed and one-way in their nature, while in the period of economic crisis they stabilize and a group of destination regions is getting narrowed down.

Using our condition we derive the main results of Rosenberg, Makagon and Salehi, and Miamee without the assumption that X and/or Y are Hilbert spaces. In addition we relate the dilation problem to the problem of factoring a family of operators through a single Hilbert space.

An operator-theoretic analogue of Rényi's Condition is introduced. It is proved that under some additional assumptions this condition implies the L¹-convergence of the sequences (a) and (b) to a unique g₀ ∈ G. The general result is applied to some smooth Markov maps in $ℝ^d$. Also the Bernoulli property is proved for a class of smooth Markov maps in $ℝ^d$.

Opis:
The economic collapse in the Russian Federation observed in the years 2014-2016 is a result of overlapping negative trends both internally and externally. It should be emphasized that the economic shock caused by external factors in the form of economic sanctions imposed on Russia by Western states and the fall in oil prices on the world markets only accelerated the onset of the economic crisis but was not the main cause of its emergence. In this case the more important was an ineffective economic policy, which made economic development dependent on the prices of natural resources, primarily energy resources and it led to a deep structural crisis. In this context, the term “lost decade” has been used to emphasize the fact that the authorities have lost the chance to carry out deep structural reforms. Necessary and extremely costly economic, political and social reforms should were to be carried out during the economic prosperity that was fueled by persistent high oil prices. Introducing the above reforms during the crisis may not be feasible, however, the complete abandonment of such projects will make it impossible for the state to protect itself against future crises.

We consider the skew product transformation T(x,y)= (f(x), $T_{e(x)}$) where f is an endomorphism of a Lebesgue space (X,A,p), e : X → S and ${T_s}_{s \in S}$ is a family of Lasota-Yorke type maps of the unit interval into itself. We obtain conditions under which the ergodic properties of f imply the same properties for T. Consequently, we get the asymptotical stability of random perturbations of a single Lasota-Yorke type map. We apply this to some probabilistic model of the motion of cogged bits in the rotary drilling of hard rock with high rotational speed.
