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:
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).

Opis:
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:
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.

Opis:
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.
