Corporate social responsibility (CSR) and sustainable development practices and employer branding (EB) significantly influence the effectiveness of recruitment processes, human resource management (HRM), and an employer’s image. The main aim of this study was to assess the effectiveness of internal and external CSR practices in an international corporation operating in Poland. The empirical study consisted of two stages. In the first stage, an in-depth interview was conducted with a group of managers in the examined company. In the second stage, the company’s employees and local residents (non-employees) were surveyed with the use of questionnaires. The study demonstrated that CSR activities addressing environmental issues were most effective. External CSR practices received greater recognition among white-collar (office) employees, whereas blue-collar (manual) employees were more appreciative of internal CSR measures—in particular, financial support schemes. The effectiveness of internal and external CSR practices has been rarely compared in the literature, and the present study was undertaken to fill in this knowledge gap.

Wind energy (WE), which is one of the renewable energy (RE) sources for generating electricity, has been making a significant contribution to obtaining clean and green energy in recent years. Fitting an appropriate statistical distribution to the wind speed (WS) data is crucial in analyzing and estimating WE potential. Once the best suitable statistical distribution for WS data is determined, WE potential and potential yield could be estimated with high accuracy. The main objective of this paper is to propose a novel approach for calculating wind energy potential. For this purpose, the Efficient Global Optimization (EGO) technique was proposed for fitting a statistical distribution to WS data and the performance of the technique was compared with genetic algorithm (GA), simulated annealing (SA), and differential evolution (DE). Performance metrics showed that EGO is providing better estimations compared with GA, SA, and DE. Based on Weibull parameters obtained by using EGO, potential WE and potential annual revenue were estimated for Gdańsk, which is the capital of Pomerania Voivodeship in Poland, in the case of having city-type wind turbines in the city center. Estimations for Gdańsk showed that city-type wind turbines might be helpful for producing electricity from WE in the city without being limited by constraints such as having a long distance between wind turbines and buildings. If such wind turbines were erected on the roofs of residential buildings, malls, or office buildings, there is a possibility that part of the electric energy needed for such buildings could be generated using WE. However, this topic should be further investigated from technical and financial perspectives.

After Poland joined the European Union, the support system for entities operating in the sphere of agrobusiness took the institutionalized form. These entities exert a great influence on the functioning of the entire agribusiness sector. In order to perform their tasks efficiently and effectively, the agencies have to use appropriate management tools. The purpose of this study is the presentation of the concepts of NPM as a management model for public organisations currently introducing agricultural policies and rural developments in Poland. The methods of literature analysis and documents analysis containing the procedures of management in the organizations implementing agricultural policy in Poland were used. The method of comparative analysis was also used in the presented research. The research shows that agencies should depart from the measurement by focusing on procedures often controlled internally, which is typical for public administration, and aims to measure the effects of procedures, i.e. to measure the results achieved.

Business management in a culturally diverse environment, that is acting in different business cultures, is one of the major challenges facing managers nowadays. Cultural differences among societies have been known to exist for ages, but a holistic view of their impact on the business culture in particular countries, development of cultural typologies and studies into the nature of interactions between the business and organisational culture date back to the 1980s. The acceleration of social, technological and demographic changes, a more rapid process of globalisation as well as some disturbances, such as the COVID-19 pandemic, the war in Ukraine or the intensifying rivalry between China and the United States of America, increase organisational uncertainty. Such changes require a new cultural sensitivity as well as new, modified systems of values. The objective of this study has been to determine and compare the Polish and Portuguese business cultures. To this end, the contemporary Polish and Portuguese business cultures have been analysed according to the 6D Hofstede model.

This paper is an attempt to show what environmental and spatial consequences will be brought by the construction of the southern ring-road of Olsztyn, which is a linear investment. It also justifies the choice of the location from among four variants that were taken into consideration at the planning stage. The area in which the ring-road is located is characterised by particularly precious natural values due to the occurrence of rivers, lakes, diversified relief, rich flora and fauna or bird refuges. Many of these elements are covered by legal forms of natural protection. As a result of numerous discussions between planners, ecologists and the local community, the best variant of the course of the ring-road was chosen, which is the subject – matter of the analysis presented below.
