Opis:
Objectives: The aim of the study was to verify whether simultaneous responses from the muscular and circulatory system occur in the driver's body under simulated conditions of a crash threat. Materials and Methods: The study was carried out in a passenger car driving simulator. The crash was included in the driving test scenario developed in an urban setting. In the group of 22 young male subjects, two physiological signals - ECG and EMG were continuously recorded. The length of the RR interval in the ECG signal was assessed. A HRV analysis was performed in the time and frequency domains for 1-minute record segments at rest (seated position), during undisturbed driving as well as during and several minutes after the crash. For the left and right side muscles: m. trapezius (TR) and m. flexor digitorum superficialis (FDS), the EMG signal amplitude was determined. The percentage of maximal voluntary contraction (MVC) was compared during driving and during the crash. Results: As for the ECG signal, it was found that in most of the drivers changes occurred in the parameter values reflecting HRV in the time domain. Significant changes were noted in the mean length of RR intervals (mRR). As for the EMG signal, the changes in the amplitude concerned the signal recorded from the FDS muscle. The changes in ECG and EMG were simultaneous in half of the cases. Conclusion: Such parameters as mRR (ECG signal) and FDS-L amplitude (EMG signal) were the responses to accident risk. Under simulated conditions, responses from the circulatory and musculoskeletal systems are not always simultaneous. The results indicate that a more complete driver's response to a crash in road traffic is obtained based on parallel recording of two physiological signals (ECG and EMG).

Opis:
. The problem of teaching methods classification doesn’t lose its importance nowadays, because it gives the opportunity to analyze each method potential and to identify ways for its improvement, further development and implementation. A large number of approaches to teaching methods classification exists due to the complexity of the study object and seriousness of the tasks set by society before the modern professional school. The use of the memberwise disjunction mechanism in training methods classification which allows to take to the account wider range of different teaching methods symptoms is proposed. Visualization of the proposed classification with the help of graphs preserves the informational content of the multivariate data in a convenient, human-readable form, simplifies the perception of such classification and focuses attention on its features. Depending on the objectives of effective learning provision, it is possible to change the dominant criteria, and accordingly choose an effective, in this case, teaching methods. In the given example, a logical connection between teaching methods and students’ types of consciousness and thinking is shown.

Opis:
Research background: Companies are required to implement Corporate Social Responsibility (CSR) policies to mitigate the adverse social and environmental effects of their activities and gain legitimacy in the eyes of society. Sustainability initiatives are costly for companies but, at the same time, they are important value-creation drivers. Retail and institutional investors are increasingly choosing portfolios based on CSR performance. However, the relationship between CSR and market beta has hardly been studied at all in the literature, and no direct comparison of the U.S. and European markets has been conducted. Purpose of the article: The two fundamental variables that define an investment are return and risk, and the appropriate risk-return combination depends on the profile of the investors. This research aims to analyze the relationship between CSR and market risk, understood as price volatility and measured by market beta in the U.S. and European markets. Methods: Companies listed in the S&P 500 and Euro Stoxx 300 indexes from 2015 to 2019 were examined using OLS regressions with instrumental variables (IV) and fixed effects panel data. Findings & value added: The results show that those companies with higher CSR have betas below the market index in the U.S. market as well as lower volatility, and are, therefore, more appropriate choices for risk-averse investors. However, this relationship was not confirmed in the European market. This difference may be justified by two reasons: 1) The non-adherence of the United States to the Kyoto Protocol, resulting in less strict legal regulations than in Europe; 2) In the U.S. market, betas are more aggressive, while in the European market they are more defensive, with little margin for reduction. This research contributes to the current state of knowledge by providing empirical evidence that social, environmental, and corporate governance sustainability practices reduce stock volatility in the U.S. capital market, which is highly relevant for private and institutional investors who make their investments based on moral criteria. The results are current and reliable since they cover a broad and recent period for two of the most important stock market indexes.

Opis:
Considering the current conditions in environmental education and training in Europe and the world, it is essential to put emphasis on the increase of the environmental literacy of pupils in the educational environment. The paper presents findings of the conducted research focused on the regional identity in relation to environmental literacy of pupils. The empirical research was of a quantitative-qualitative character. The subject of the research was the level of environmental literacy of pupils of primary education and selected aspects in its development in educational process. The research was conducted in 630 schools from all over Slovakia. In the paper we focus mainly on the findings obtained from questionnaires completed by primary education pupils and from interviews carried out by teachers. The research findings highlight the need of pupils for direct contact with nature with regard to the improvement of their level of environmental literacy.

Opis:
Objective. The aim of this prospective cohort study was to translate, validate and perform a cultural adaptation of the Polish version of the Swiss Spinal Stenosis Questionnaire (P-SSSQ), a disease-specific questionnaire for assessing symptom severity, physical function and satisfaction with treatment in patients with lumbar spinal stenosis (LSS). Materials and method. Patients were prospectively recruited at two orthopedic centres in Krakow, Poland, between January 2011 – October 2016. During the interview, each patient completed the P-SSSQ, SF-36 Health Survey, and a demographic data questionnaire. After translation, cross-cultural adaptation, and pilot testing, assessment was made of the internal consistency, test–retest reliability, construct validity, and responsiveness of the P-SSSQ subscales. Results. Finally, 171 consecutive patients were included in the study. Cronbach’s alpha and ICC values were above 0.8 for all three subscales of the P-SSSQ. The symptom severity domain was highly negatively correlated with physical functioning and bodily pain of SF-36, with Pearson correlation coefficients of -0.68 and -0.63, respectively. The physical function domain was highly negatively correlated with physical functioning (r = -0.62). The satisfaction subscale was also highly negatively correlated with the change in the symptom severity (r = −0.61) and physical function scale (r = −0.65). Conclusions. The proposed version of the P-SSSQ showed excellent measurement properties and can be considered validated for use in Polish. It is easy to understand, quick to complete, and the psychometric properties of the original version are maintained.
