Abstract

The aim of the article is to analyse the possibility of using the elements of a multidimensional comparative analysis in order to create a tool enabling a comprehensive assessment of a person’s competencies, and comparing it with the requirements set in a specific vocational situation. An illustration of such possibilities is the presentation of a tool for assessing competencies prepared under the international Go4FutureSkills project. A competency profile was defined as a set of desirable competencies with the level of knowledge or skills required for a given profession/position assigned to each of them. The competency matrix created in this way serves as a basis for the comparison of the results obtained by the people using the tool. In its present form, this tool can be used by students and graduates majoring and specialising in logistics, as well as by employees from the logistics industry.

Abstract

Extending working life is an important challenge for modern economies. In Poland, 40% of people aged 50–64 are economically inactive. In the population of people with disabilities, this percentage is much higher (78%). The aim of this paper is to assess the individual factors for extending the working life of Poles aged 50–64 and their comparison between people with and without disabilities. The empirical analysis is based on the national survey, Social Diagnosis (for people aged 50–64). The analysis was carried out with the application of logistic regression, as well as the Student t-test, the Mann-Whitney test, the chi-squared test of independence. The logistic regression results show that the factors of extending working life for people with disabilities are different than for others – statistically significant determinants are formal outcomes of human capital development (regarding individuals without disabilities, the list of factors extending working life is more extensive).

Abstract

It is important to obtain a deeper understanding of the social context of smoking, which may support finding new ways to hinder the development of a smoker’s identity. The authors developed the Picture Based Recognition of Smokers (PBRS) method in order to understand the identity markers of the social and visual contexts related to adolescent smoking. The differences in identifying non-smokers and smokers between traditional text-based questionnaires and PBRS were compared in a discriminatory analysis conducted by comparison clouds and correlograms. The ability of these methods to predict adolescent smokers was tested with a regression model combined with permutation analysis. The result of word clouds confirmed that interpretations of the visual identity markers of pictures differ between non-smokers and smokers. PBRS had a better success rate of predictions than the text-based questionnaires. This approach develops preventive interventions which do not stigmatize the intervention group.

Abstract

The growing popularity of electric scooters has resulted in the dynamic development of this market on a global scale. Each potential customer has different preferences and therefore should be able to choose a scooter that meets their expectations. The study used a dataset comprising 42 scooters available on Polish market with their specifications. The aim of the study was to present the structure of the electric scooter market in Poland and carry out a market segmentation. On the basis of an arbitrary decision, under the terms of the quotients of the coefficients in successive stages of combining into clusters, two and four classes of scooters were distinguished. The comparison of clusters with the adopted price ranges proved that, with the increase in the performance of the electric scooter, the price rises. Such a combination can help customers choose the cheapest scooter from a given market segment, according to their budget constraints and personal preferences.

Abstract

The purpose of this article is to identify the relationship between the declared activities in line with corporate social responsibility and the implementation of diversity management concepts. The paper presents the essence of corporate social responsibility as an element of company strategy, and the importance of the concept of managing diversity of employees in building an organizational culture based on mutual respect and a sense of security of employees, and thus increasing the efficiency and innovation of the company, by recognizing the individual characteristics of the people employed. An in-depth interview method was used, conducted on the basis of a non-standardized interview questionnaire with HR directors of domestic companies. The obtained empirical material was presented as a case study.

Abstract

Data have shapes, and human intelligence and perception have to classify the forms of data to understand and interpret them. This article uses a sliding window technique and the main aim is to answer two questions. Is there an opportunity window in time series of stock exchange index? The second question is how to find a way to use the opportunity window if there is one. The authors defined the term opportunity window as a window that is generated in the sliding window technique and can be used for forecasting. In analysis, the study determined the different frequencies and explained how to evaluate opportunity windows embedded using time series data for the S&P 500, the DJIA, and the Russell 2000 indices. As a result, for the S&P 500 the last days of the patterns 0111, 1100, 0011; for the DJIA the last days of the patterns 0101, 1001, 0011; and finally for the Russell 2000, the last days of the patterns 0100, 1001, 1100 are opportunity windows for prediction.

Abstract

The main purpose of the paper is an expert assessment of the relationship existing between selected indicators carried out using a relatively new tool in economic sciences: Fuzzy Cognitive Maps. The effect of its application is a graphical presentation of the relationship between the factors identified as the key ones. In the paper 23 indicators, describing four selected goals in the Strategy for Sustainable Development, 2030 Agenda were selected. It is assumed that the sustainable development goals should be related but according to the experts opinion this only applies to some indicators. This kind of relationships can be certainly identified in the case of the goals describing social and economic development, but often also economic and environmental development. However, the research results presented in the paper do not always confirm the existence of connections between individual indicators selected for the description of the goals of sustainable development. The paper tries to explain this problem.

Abstract

The paper deals with an evaluation of the quality of services provided by healthcare organizations. First, an index representing a patient’s health condition is described, then its changes before and after being treated by a given entity are employed as a criterion to assess the operations of this entity. The index of a patient’s health condition is based on the theory of survival analysis, while a model of random effects is used to determine the quality of services based on health value added.
