If corporate social responsibility (CSR) is expected to work efficiently, there should be a standardised approach for implementation of the CSR concept for all businesses, including companies operating in the energy sector. Although many companies declare compliance with CSR standards, further investigation should be undertaken to evaluate if and how those standards have been applied in practice. The aim of this research is to examine the level of standardisation of the CSR activities within Polish energy companies and explore the good practices developed by those companies. The Polish energy companies have been selected for the investigation as the literature review we conducted demonstrates that there is limited research in this area and there is a knowledge gap regarding how Polish energy companies apply CSR regulation in practice. To accomplish the stated aims, the following research questions were developed: (1) What is the essence of applying the CSR concept in Polish energy companies, and at what level of development is the concept applied? (2) To what extent do Polish energy companies have a common approach to the CSR concept, and in what areas are there differences? (3) To what extent have Polish energy companies applied global CSR standards and solutions? (4) Is there a gap between the declared measures of CSR and their actual implementation in Polish energy companies? The research methodology of this study is based on a systematic literature review of the sources acquired from databases such as ProQuest, Emerald, SCOPUS and the Jagiellonian University Library. The multiple case study approach was identified as the most suitable research tool. Companies for the study were selected according to their affiliation to the energy sector and listing on the main market of the Warsaw Stock Exchange. These two assumptions allowed us to base this study on the largest Polish energy companies that have international status. Six areas of CSR annual report disclosures have been identified and used for the investigation and analysis. This research looks at similarities and difference between these six aspects of CSRs disclosed by Polish energy companies. The investigation allows us to conclude that the top three energy companies use similar tools to build their CSR strategies: formalised CSR concept, published CSR reports, disclosure of CSR information on the company website, CSR related activities offered to stakeholders, obtained CSR certificates, and CSR awards. This indicates the existence of a standardised approach to CSR across Polish energy companies.

The article refers to the issues of financial profitability of undertaking CSR activities, which is widely reported in literature. The four largest electricity producing companies in Poland were selected for the analysis. The research period covers the years 2009–2019, when the index of socially responsible companies was operating on the Warsaw Stock Exchange. The main purpose of the article is to compare the profitability ratios and quotations of energy companies in Poland declaring themselves socially responsible with companies of the same sector that have not expressed such a declaration. The results obtained on the basis of descriptive statistics, concerning profitability ratios and stock market quotations, indicate no relationship between their level and stability and the companies’ declarations of compliance with social responsibility. Companies declaring themselves socially responsible were placed in the ranking between the results of companies that did not belong to the indicated index. This may be the result of the specific situation of energy companies in Poland.

Stroke is an important medical and social problem, and stroke risk assessment tools have difficulty on the interaction of risk factors and the effects of certain risk factors with analysis by age, gender, race, because this information fully available to global risk assessment tools. In addition, these tools tend to be focused and usually do not include the entire range of possible factors contributing. The aim of the study was to conduct a comparison of brain vascular lesions pool with ischemic stroke (II) based predictive analysis and assessment of the main risk factors in patients with primary and recurrent ischemic stroke. Prognostically significant risk factors for recurrent ischemic stroke is not effective antihypertensive therapy, multiple stenoses any one pool vascular brain, duration of hypertension (AH) over 5 years and regular smoking patients (p<0.001). In the initial localization in the second vertebrobasilar recurrent stroke was significantly (p<0.05) more developed in the same pool in women than in men; and the localization of the primary carotid AI in the pool, re-developed stroke often unreliable in the same pool in women than in men.
