The paper presents the analysis of the influence of selected features of unemployed persons on unemployment duration. Theoretical considerations go along with an empirical study based on individual data from Local Labour Office in Szczecin. The research hypothesis states that features of unemployed persons such as the level of education, sex, work seniority or age have a meaningful influence on unemployment duration. Recent studies usually used event history analysis, inflow-outflow analysis of the labour market or logit models. This research is unique because of the application of one of the methods of multidimensional analysis – correspondence analysis. This method allows analysis of multidimensional relationships between categories of nominal variables. From the results obtained it could be stated that strong relationships between unemployment duration and features of unemployed persons exist (apart from sex).

Sources of capital to finance companies in the SME sector is one of the basic conditions for the functioning and development of enterprises, especially in the early phase of their development. Increasingly popular is the use of capital market instruments, Private Equity, Venture Capital, Business Angels or Mezzanine. Funding of this kind can finance risky investments in return for a higher expected rate of return on capital. Access to financial resources and the conditions under which entrepreneurs can use them can determine the introduction of new technology, new products and services, expand distribution channels, implement changes that may lead to the growth in competitiveness and above all, innovation, thus the growth of the company. The paper presents results of statistical analysis of the venture capital and private equity funds investment strategies in selected countries. As a result investment profiles are created.

The paper attempts to verify the hypothesis of the existence of generational differences in the perception of the conditions and quality of work. The research issues considered in this paper are chosen following the regularities observed in the labor markets indicating that special attention should be paid to two age groups: the youngest and the oldest persons. The highest unemployment rate in the EU is observed among young people who encounter various barriers at the beginning of their professional career. On the other hand, the older group of people is expected to provide an important contribution to the labor force to face the problem of aging societies. The objective labor market indicators should be confronted with the results of the subjective opinions of the labor market participants in order to have a comprehensive outlook of the situation. The chosen multivariate method is applied to analyze the opinions of both young and older Europeans taking into consideration the spatial diversity. The opinions about current work given by European Social Survey respondents are analyzed, among others these are the variety of current work, possibilities of learning new things at work, effort-salary relation, support received from other workers etc. The paper presents some results obtained from the applications of correspondence analysis whose usefulness is determined by the measurement scales of the regarded variables.

Presented in this paper the method of graphical presentation of the relationship between nominal variables and their categories gives the opportunity for an extensive diagnosis of dependence variables. Correspondence analysis and mosaic plots are based on the same grounds, i.e. contingency table or multi-way contingency table. Correspondence analysis can be used in the study of relationships between two or more nominal variables without limiting the number of categories. In the case of many variables, the multidimensional contingency table is used very often. Only the difficulty of construction of such a table and the combined variables can affect the decision of a researcher about the validity of using this solution. For mosaic plots the situation is different. These graphs represent very well the relationships between two categories of nominal variables with few categories. The introduction of another variable to the study, which is described by two or three categories, is also not too problematic, and the graph is easy to interpret. However, if in a multi-way contingency table variables are a combination of several primary variables, described with many categories, the mosaic plot is no longer as clear as the projection made in correspondence analysis.

Private equity and venture capital (PE/VC) funding is the provision of equity capital by financial investors to non-quoted companies with high growth potential. It has a particular emphasis on entrepreneurial activities rather than on mature businesses. PE/VC investors differ on several dimensions including: investment targets, screening evaluation methods, governance mechanisms, and objectives. The paper is a conti nuati on of the discussion that concerns investment strategies of PE/VC funds. While studying the PE/VC market it is important to analyze the origin and structure of capital. The authors assumed that different types of investors have different investment strategies. Our research is an attempt to answer the following research question: whether the investor type, on the European PE/VC market, has an impact on the selection of industries. The paper presents results of statistical analysis of venture capital and private equity funds investment strategies in selected countries.

The deterioration of the general investment climate, the economic recession, and changes in consumption patterns caused by the COVID-19 pandemic have forced various foreign investors to restrict or suspend investments. One of the possible reactions by investors to the coronavirus crisis is divestment. This article aimed at detecting and analysing the regularities between the risk of foreign divestment in various industry branches and the destinations of FDIs at the level of NUTS 1 macroregions of the Visegrad Group countries during the COVID-19 pandemic, using correspondence analysis. The results of the assessment of the risk of foreign divestment in NUTS 1 macroregions of the Visegrad Group countries are characterised by diversity in terms of territorial and sectoral layout, depending on the analysed scenario of the COVID-19 pandemic development. It is hard to clearly indicate a macroregion which, irrespective of the scale of the spread of the disease, could be perceived by foreign investors as invariably highly risky or characterised by a constantly low risk of divestment.

Research background: In the last few years, e-commerce market has increased in population shares, but the situation has changed dramatically since the Covid-19 pandemic. Electronic marketplaces have changed due to rapid digitalization and shopping. Online services offer the possibility to choose a different delivery method such as home delivery or out-of-home delivery. This aspect of the e-commerce market faces an increased interest among practitioners and academia in the field of sustainable last mile deliveries. Interestingly, the subject literature consists of papers analyzing the e-commerce impact on the last-mile delivery. However, the identification of factors for choosing a delivery method and factors that motivate e-customers to choose an eco-friendly delivery method is still an unrecognized field of research. Purpose of the article: The authors of the paper focused on the e-customer perspective on sustainable deliveries in cities. Thus, the main purpose of the paper is to compare factors among the generations that motivate e-customers for choosing a delivery method. Methods: The research was conducted among 1.110 e-customers in Poland in 2021. The paper aims to answer the following research question: what factors motivate each generation for choosing a delivery method? To answer the above-mentioned question, the correspondence analysis (MCA) is prepared that help to identify and compare factors in each generation. Findings & value added: The original research procedure focused on the use of multivariate statistical methods in the study of e-customers’ preferences. The analysis revealed three clusters of e-customers in terms of pro-sustainable factors: (a) aged 65+ without pro-sustainable tendency, (b) aged 18–64 with pro-sustainable attitudes, and (c) mixed with no identified delivery preferences. As a result of the research, it can be concluded that the parcel price and the possibility of free return are still the most important factors in choosing the delivery method. From a business/practical perspective, the research results can be used by companies that are the main stakeholders in last mile deliveries, including mainly forwarders and transport companies.

Research background: Improving business conditions and SME development are signs of a country's macroeconomic stability. The issue of identifying and removing barriers to the development of firms in the SME segment is a priority in all countries with developed economies and its importance is currently increasing. Purpose of the article: The main aim of this paper is to explore possible differences in entrepreneurs' perception of the business environment based on the industry in which the company operates. The analysis contains also a national view, where a comparison between the Czech Republic and the Slovak Republic is performed. Methods: Correspondence analysis was used to achieve the research objectives in order to examine the relations between the categorical variables. Its application is beneficial in cases where the graphic output is clearer than the numerical one. Findings & Value added: The presented research makes it possible to identify problematic aspects of doing business in each sector and to create support mechanisms for the creation of effective structural policies. Entrepreneurs from the Czech Republic's Production and Transport sectors agree with the statement that the business environment in the country is suitable for starting a business. As for business environment's suitability for doing business, neither Slovak nor Czech entrepreneurs sector-wide agreed with the given statement. Czech entrepreneurs from the Services, Trade and Construction sectors, respectively, agree, fully agree with the statement that the business environment in the country is reasonably risky and allows for doing business. In the case of entrepreneurs from Slovakia, no significant correspondence is observed. Findings regarding the statement that the business conditions in the country have improved over the past five years are the following: In the Czech Republic, there is a perfect correspondence of the Transport sector and the agreement with the given statement. In the Slovak Republic, agreement was found with the given statement in the Transport sector and neutral position in the Production sector.

This article attempts to determine the relative chronology of the Kietrz cemetery of the Lusatian culture proceeding from the stylistic development of forms and ornamentation of vessels coming from selected pottery inventories. The co-occurrence matrix of forms and ornaments, developed from the sources described above, was examined using correspondence analysis. Graphic representation of the results forms a quite distinct arc-shaped layout in the plot of two principal axes. Correspondence analysis was also conducted for the identified types of decoration. The results, transposed into a two-dimensional diagram, show a different, not arch-like distribution. Objects and variables form two separate clusters. Detailed analysis of the two diagrams allowed for many valuable conclusions: (1) phases of vessel form development are polythetic assemblages, which means that they are formed by specific combinations of attributes or their frequencies rather than by strictly defined sets of phase-unique attributes; (2) in the development of pottery forms, one can observe a continuous evolution between phases BrC2 and HaC, i. e. in the period spanning nearly 800 years (ca 1380–600 BC). This confirms earlier conclusions, based on planigraphy data, concerning the uninterrupted functioning of the cemetery; (3) development of pottery decoration followed a different pattern – a “revolutionary” change in HaA was followed by a continuous development until the end of early Hallstatt period, when a regression in pottery ornamentation probably took place; (4) there is some discrepancy between the present results and M.Gedl’s chronology with respect to the older phases of vessel form and decoration development (among other things, the present results suggest dating the appearance of bossed decoration as early as BrC2).

Many of the problems that the world faces today appeared as the result of unstable development. Global climate change, resource depletion, space debris, poverty, inequality, and threats to global security are the main but not the only challenges for modern humanity. The important issue in studying the problems of sustainable development of the countries in the world is the development of strategies that would give an opportunity to avoid environmental and social catastrophes. The correspondence analysis is used to identify the relationship between the Happy Planet Index (which is an aggregate indicator of achievements in the key aspects of human development, such as life duration and quality, distribution uniformity, access to knowledge, and preservation of environment) and Gross National Income (one of the basic metrics of the population welfare level). The analysis led to the conclusion that the income level of the population is not the main factor in assessing the level of sustainable development of a country. The obtained results can give important and useful information for social institutions and politicians.

It is truism to say that for an archaeologist the question of chronology is particularly important. In relation to Tarnobrzeg Lusatian Culture, this topic was frequently raised, which in the case of its early and late stages gave satisfactory results. There are numerous determinants of these phases, and they can also be divided into smaller periodical stages. The dynamics of change is well understood. However,p hase II is far more problematic. Basically, it is represented by one type of vessel. In addition, the 150–200 year phase is very compact in terms of inventory and it is almost impossible to identify older or younger materials. The problem of its decline also needs to be emphasized, where when treated through the prism of the San River style as it usually is, it should be prolonged to HaD. The author, using the correspondence board, tries to indicate materials which can be related to the older and younger episode of the second phase of Tarnobrzeg Lusatian Culture.

Celem badań przeprowadzonych w ramach prezentowanego artykułu jest wskazanie analizy korespondencji jako metody niezwykle użytecznej w rozpoznawaniu współwystąpień kategorii zmiennych wyróżnionych w trakcie egzaminu gimnazjalnego. Wskazanie powiązań między kategoriami zróżnicowanych zmiennych może być wskazówką do dalszej modernizacji systemu edukacji, tak by dostęp do wiedzy nie był ograniczany. System edukacji w Polsce poddano radykalnej reformie, którą zapoczątkowano w 1999r. Jej celem było podniesienie jakości kształcenia oraz dopasowanie systemu edukacji do wymagań gospodarki opartej na wiedzy. Jednym z najważniejszych rozwiązań proponowanych w reformie szkolnictwa było wprowadzenie nowej struktury szkolnictwa. W trakcie reformy systemu edukacji wprowadzono między innymi egzamin gimnazjalny, którego wyniki z lat 2003-2010 wzięto pod uwagę w prowadzonej analizie. Egzamin ten jest jednak powszechny i obowiązkowy. Dysponowano wynikami Centralnej Komisji Egzaminacyjnej dla poszczególnych uczniów w województwach opolskim i dolnośląskim z podziałem na szkoły, gminy, płeć oraz tematyczne obszary egzaminacyjne w zakresach przedmiotów matematyczno-przyrodniczych i humanistycznych. Przeprowadzono analizę korespondencji wykorzystując podejście klasyczne i dla wielu zmiennych.

The aim of the research presented in this article is to indicate the correspondence analysis as a very useful method in recognizing the categories’ associations of variables identified in the gymnasium exam. Indication of the relationships between categories of different variables may give a recommendation to further reform of the education system so that the access to knowledge is not limited. A radical reform of the educational system in Poland started in 1999. Its aim was to improve the quality of education and to adjust the education system to the requirements of the knowledge-based economy. One of the main solutions proposed in the reform was the introduction of the new education structure. An external, universal and compulsory gymnasium exam was implemented and its results from the years 2003-2010 were taken into consideration in this scrutiny. The analysis was based on the results collected by the Central Examination Board for individual students in the dolnośląskie and opolskie voivodships with regard to school, community, gender and exam thematic areas in the fields of humanities, mathematics and science. The correspondence analysis was performed using both simple and multiway approaches.

Nominal data, due to their nature, are often analysed statistically in a quite limited and traditional way. Usually they come from open-ended or simple/multiple choice questions. In typical research projects, such data are often presented in the form of more or less complex tables (including contingency tables) and standard charts. The author’s experience shows that such a visualisation is perceived as boring, especially by younger people, accustomed to the presentation of content in the form of infographics. The article presents examples of data analysis and a visualisation of the nominal data based on the results of the author’s research, including theoretical reflections on the techniques and tools used. The starting point is the raw text data from the responses to the open-ended questions subjected to analyses of the frequency of words and expressions, including its visualisation through word clouds. The next step is categorization and tabulation at the level of individual variables including the visualisation of categories, to assess the contingency between two nominal variables (or the nominal and the ordinal one), including visualising the relationships via chord diagrams and the correspondence analysis.
