Opis:
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).

Opis:
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.

Opis:
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).

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.

Opis:
The article focuses on the consumption of goods used by consumers of different generations from 3 different countries: Albania, Poland and Portugal. The aim of the analysis was to identify respondents‘ indications concerning: (1) knowledge of the definition of the circular economy, (2) declared by respondents places of purchase of used products and (3) type of purchased products used by respondents. The analysis was conducted among 495 respondents from Albania, Poland and Portugal representing three generations (X, Y, Z). Correspondence analysis was used for statistical data analysis. Statistically significant differences in knowledge of the definition of the circular economy were shown between respondents from Albania, Polish and Portugal. It was also found that respondents‘ preferences regarding the place of purchase of second-hand goods are differentiated (at a statistically significant level) by nationality and year of birth (generation). The obtained results open the possibility of further research aimed at identifying different behaviors among these groups of consumers. The presented work, both in the cognitive and application part, can be a source of knowledge and popularization of research, as well as a source of inspiration for in-depth reflection and scientific discussion. The analyses presented in the publication may complement the existing research in the field of circular economy. Extending the survey to other EU countries can help define a strategy for policymakers, manufacturers and retailers to make greater use of circular economy solutions, while maintaining the viability of their operations.

Artykuł nie zawiera streszczenia
In this survey paper the author critically examines all aspects of factor analysis: the data structure it is intended to describe; the methods of analysis aimed at estimating that structure; and the interpretations placed on the results of the analysis. The first part of the paper deals with the theory underlying the technique. It is shown that, in general, the estimation problem of factor analysis is insoluble.  In particular, if there are p variables, and m factors are to be identified, there are indeterminacies in the model itself unless p is at least 2m+1; even when the condition is satisfied,  the solution is determinate only up to a group of rotations. After a brief discussion of principal component analysis, principal factor analysis is described. It is shown by examples that "principal factor analysis may give factor estimates that bear no relationship whatever to the true values''. Even with maximum likelihood methods, which are briefly described, there are indeterminacies. It is shown with synthetic data that a restriction usually imposed to achieve uniqueness does not necessarily retrieve the originally applied parameters. The situation is further complicated by the rotation of factors to achieve either a simple structure or a psychologically meaningful solution. The second part of the paper describes the testing of factor analysis programs using artificial data. The general conclusion from this practical study is that, while the numerical accuracy of the programs is satisfactory, the results obtained do not correspond to the original structure of the data, but produce "factors'' that were not initially present. The examples also show that, when matrices of estimated loadings are subjected to an orthogonal transformation, "all resemblance to the true loadings disappeared''. The author makes various pungent comments on the findings from this study.    The paper concludes with a short section on the clustering of variables into uncorrelated sets.

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.
