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.

Drugą podstawą przyjaźni jest jej przyszłość, tj. horyzonty, perspektywy, które ona stwarza. Zasadniczym rysem tych perspektyw jest zdolność do stawienia czoła tym problemom, które w innych związkach nie mogły być pozytywnie rozwiązane. 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.

Opis:
The article discusses the measures and models of enterprises innovativeness developed by researchers representing branch economy. Firstly, the attention was given to the traditional measures of firm innovativeness, both input and output ones. Were presented its advantages and disadvantages. The next part of the study concentrates on firm innovativeness modern measures, which, among others, refer to the managerial concepts of open and networked innovation. Finally, the evolution of firm innovativeness models was discussed.
W artykule zostały omówione miary oraz modele innowacyjności przedsiębiorstw opracowane przez badaczy reprezentujących ekonomię gałęziową. W pierwszej części omówiono tradycyjne miary innowacyjności przedsiębiorstw, dzieląc je na miary nakładowe oraz wynikowe. Przedstawiono zalety oraz wady tych mierników. W dalszej części opracowania skoncentrowano się na nowoczesnych miarach innowacyjności przedsiębiorstw, które m.in. odwołują się do menedżerskich koncepcji otwartej oraz sieciowej innowacji. W zakończeniu zaprezentowano ewolucję modeli innowacyjności przedsiębiorstw.
