Simulation of dynamic response of vibroisolated object
No full textThis paper presents application of Finite Element Method in designing of a vibroisolated object. A model of power generator of 113 MW was chosen for the analysis. Such the generator is used in one of power plants in Silesia district. Several frequency domain dynamic analyses aimed at assessment of influence of vibroisolation on acceleration level of the generator foundation were performed. Three different models of the generator were considered. For the purposes of verification of the obtained results measured vibration accelerations were used
Relationship between corporate sustainability performance and corporate financial performance: evidence from U.S. companies
No full textResearch background: Sustainable development at the enterprise level is understood as the integration of economic, environmental and social dimensions aimed at meeting the needs of all firm?s stakeholders in the present and in the future. Therefore, it is crucial to evaluate the relationship between economic, environmental and social sustainability performance of a company and its financial performance.
Purpose of the article: Considering the business model for sustainability as well as the debatable results of empirical research on the relationship between corporate sustainability performance (CSP) and corporate financial performance (CFP), the essential aim of the paper is to answer the question whether the improvement of corporate sustainability performance in its all particular dimensions brings about higher total revenues (TR) of a company.
Methods: The main method of empirical research is panel regression models based on Cobb-Douglas production function, which has been extended to include variables of corporate sustainability scores. The selection between pooled OLS model, random-effects model and fixed-effects model has been made with the use of the F test, the Breusch-Pagan test and the Hausman test. Additionally, descriptive statistics and the Pearson correlation coefficients have been analyzed. The empirical studies were conducted in the period 2014?2019 among the 59 largest U.S. companies listed in the Fortune 500 ranking between 2015?2020.
Findings & value added: The research hypothesis assuming the existence of positive relationship between corporate sustainability performance (CSP) at both aggregate and disaggregate levels and corporate financial performance (CFP) expressed by TR cannot be positively verified. It means that the improvement of corporate sustainability performance in environmental, social and governance dimensions does not lead to an increase in TR of a company, as some empirical studies suggest
Readability, efficiency and costliness of individual retirement products in Poland
No full textResearch background: The role of supplementary pension systems in providing adequate income in old-age is increasing significantly. They are frequently analysed, but rather in terms of architecture, product forms, assets under management or tax incentives than in terms of their efficiency, costliness or readability for individuals.
Purpose of the article: The first aim of this paper is to evaluate individual retirement products in Poland regarding their linguistic readability and transparency, investment efficiency and costliness. Moreover, we examine whether there is any correlation between the analyzed characteristics of contracts that would suggest an intentional strategy by financial institutions to hide low efficiency and high costs. The second aim of the article is to assess which individual retirement products are similar to each other and which are significantly different. The research covers two types of individual retirement products (IKE and IKZE) offered at the beginning of 2017.
Methods: We used the ?Jasnopis? linguistic analysis tool to assess the difficulty level of the language used in the contracts and we conducted desk-research to analyse their transparency. We indicated the costliness and efficiency of the products by calculating the 5-year cost ratios and real average 5-year rates of return. To examine the relations between the characteristics of pension contracts, we used the Spearman\u27s rank correlation coefficient and then verified its significance with a non-parametric test. Moreover, to identify groups of products that are similar to or different from each other, Ward\u27s method was used. The study includes nearly 90% of all individual retirement products offered in Poland.
Findings & value added: For both types of retirement products studied (IKE and IKZE), we found that the more readable a contract is, the higher its rate of return is and the higher the costs charged are. Moreover, the more readable a contract is, the more transparent it is. The findings of the study provide financial institutions, the supervisor and creators of social policy with information on market imperfections and recommendations how to improve the individual retirement products offered on the market. Our research makes a unique contribution to the multidimensional research of supplementary pension systems. It also develops the understanding of how to successfully use linguistic tools in complex analyses of financial services. The results of the hierarchical cluster analysis proved that both IKE and IKZE products differ substantially and their features generally do not depend on the type of the financial provider
The effects of membership in the Polish National Cittaslow Network
No full textResearch background: Identification of the effects achieved by cities owing to their membership in the Cittaslow network plays a role not only in the development of every city, but also in the growth of national and international Cittaslow networks. Being a member of the Cittaslow network, and thereby adopting the slow city development model, affects the process of urban management by directing it towards such activities that agree with the assumed development concept. The achieved effects, manifested in the social, economic, and spatial spheres, contribute to the improved quality of life in a slow city, which in turn influences its development.
Purpose of the article: Identification of the effects of membership of Polish cities in the Polish National Cittaslow Network.
Methods: The study included a diagnostic survey method. The diagnostic survey based on a standardized survey questionnaire was used to identify the effects achieved by the Polish cities in the Cittaslow network. The survey was addressed to mayors of all member cities in the Polish National Cittaslow Network. The survey was conducted in May 2020.
Findings & value added: The most important effects to date of cities being members of the Polish National Cittaslow Network, and their scale, have been investigated. An attempt was made to determine in which areas of urban life the effects become observable in a relatively short time (a few years), and which effects are attainable after a longer period of time. Major barriers to obtaining the desired effects were also identified. The research fills in a gap in this scope, as it provides a complex analysis of the effects of the membership of cities in the national Cittaslow network as seen by the city authorities. The results can serve to make comparative analyses of the effects achieved on different levels of development in the national Cittaslow networks, particular-ly in view of the fact that the Polish National Cittaslow Network is the second largest network in the world with respect to the number of member cities
The impact of digital transformation on European countries: insights from a comparative analysis
No full textResearch background: In the era of the digital revolution, the Internet, automation and robotisation, new industrial relations and dynamic interactions among different stakeholders are giving rise to new opportunities and challenges. The changes associated with the enforcement of the ?Industry 4.0? concept require adaptation to these developments at different levels of the economy and society in order to support digital transformation.
Purpose of the article: The aim of this paper is to measure and assess the impact of digital transformation on European countries (EU). The comparative analysis of technological development in EU countries includes three dimensions: the digitalisation of society (Society 4.0), the ability of the economy to face the challenges of technological development (Economy 4.0), as well as the exploitation of ICT in companies (Companies 4.0).
Methods: The empirical section of the article was built on a two-stage analytical approach: (a) cluster analysis methods to assess differences and similarities between EU countries (Hierarchical Cluster and K-Means Cluster) and (b) the multi-criteria decision-making method (TOPSIS) to rank countries according to the adopted evaluation criteria. For the purposes of this analysis, data from the Eurostat database have been applied.
Findings & value added: The results of this analysis demonstrate the impact of technological transformation on the economy and society in EU countries grouped according to a similar level of development, such as countries with high, medium and low performance. This has contributed to indicating the cohesion in technological development achieved by each country group and to recognising the digitalisation gap between EU Member States. The novelty of this study consists in applying the multi-stage, multi-criteria analysis based on cluster analysis and the TOPSIS method, as well as the comparative analysis of the impact of technological developments on the societies and economies of EU countries. This paper extends similar studies by focusing on the application of a broad range of indicators regarding a holistic perspective including three dimensions: societies, economies and companies. The results provide valuable insights into evaluating the technological progress in European countries
The research on COVID-19 and economy from 2019 to 2020: analysis from the perspective of bibliometrics
No full textResearch background: The outbreak and spread of COVID-19 brought disastrous influences to the development of human society, especially the development of economy.
Purpose of the article: Considering that knowing about the situations of the existing studies about COVID-19 and economy is not only helpful to understand the research progress and the connections between COVID-19 and economy, but also provides effective suggestions for fighting against COVID-19 and protecting economy, this paper analyzes the existing studies on COVID-19 and economy from the perspective of bibliometrics.
Methods: Firstly, the discussion starts from the statistical analysis, in which the basic distributions of the studies on different countries/regions, different publication sources, different publication years, etc., are presented. Then, the paper shows the cooperation situations of the researchers from analyzing the related citation networks, co-citation networks and cooperation networks. Further, the theme analysis of the related studies is presented, in which the related co-occurrence networks are shown, and then the detailed analyses of the studies are introduced. Based on these analyses, the discussions about future research are presented, and finally we draw a conclusion.
Findings & value added: The analyses not only present the basic situation on the research about COVID-19 and Economy, but also show the future research trends, which can provide meaningful research expectations
The effect of the CEO media coverage on corporate brand equity: evidence from Poland
No full textResearch background: Despite increased attention in the literature to the importance of the CEO?s brand for companies, understanding of the effect of the CEO brand on the corporate brand remains limited. To contribute to this discussion, this paper investigates different facets of the impact of the CEO brand, and particularly its media coverage, on corporate brand equity.
Purpose of the article: This study investigates the relationship between the different aspects of the CEO brand?s media coverage and corporate brand equity.
Methods: Comprehensive media monitoring in the press and online sourcing of CEOs from the strongest Polish brands were conducted. For three years (2014?2017), media monitoring covered 81 CEOs, resulting in over 44,000 data points for this study. Regression analysis was conducted to determine whether a relationship exists between different facets of the CEO?s personal brand and company brand equity.
Findings & value added: This study provides a new perspective on the relationship between the CEO and corporate brands and showcases empirical evidence of the CEO brand?s relationship with corporate brand equity. It introduces two relevant and novel variables (CEO brand reach and CEO brand advertising value equivalent [AVE]) to the literature, which have been limited to the number of mentions and its sentiment. Accordingly, this study contributes to the emerging literature of CEO branding within the branding field. Contrary to expectation, the intensity of media coverage alone was not significant. Results indicate that reach and AVE of CEO media exposure are reflected in the corporate brand equity. The study also finds that negative sentiment toward a CEO?s brand negatively affects corporate brand equity. The study adds to the growing stream of literature on the role of CEO brand
The importance of evaluating inpatients? satisfaction with emphasis on the aspect of confidence
No full textResearch background: The patients? confidence in physicians, as well as in healthcare personnel in general, is an important determinant of the patients? satisfaction and their loyalty. The patients? confidence as well as their overall satisfaction is influenced by many determinants, which are in a causal relation.
Purpose of the article: The main aim of the study is to find out which socio-demographic factors influence the confidence of inpatients in physicians, nurses, other medical personnel, as well as in the treatment as such. The inpatients´ confidence is considered as an important dimension of the inpatients? satisfaction.
Methods: The questionnaire consists of 112 structured and semi-structured sur-vey questions. It was inspired by the HCAHPS survey. The questionnaire was distributed both on-line and in paper form in the Czech Republic. The dataset consists of 1,479 observations (899 females and 580 males). The descriptive statistics and binary logistic regression were used to process all data.
Findings & value added: The research revealed significant differences in the confidence of inpatients in physicians in relation to the physicians? communication styles regarding the inpatient?s gender. Males are more tolerant to the communication styles of physicians than women. There exists a relatively strong linear relationship between confidence in physicians, nurses, other healthcare professionals, and confidence in a treatment. Also, it was determined that in cases when a physician talks about an inpatient as if she/he is not there, the patient?s confidence in the medical personnel is reduced by 65%. Overall confidence in medical personnel is also gender biased i.e., in 87% of cases, women are more likely to have a higher confidence in medical personnel than men. The age of inpatients is not statistically significant and its impact on a confidence in medical personnel is neglectable. 
The effects of emotional intelligence and ethics of SME employees on knowledge sharing in Central-European countries
No full textResearch background: The research examines the impact of emotional intelligence and ethics on knowledge sharing within organizations. It examines the impact of emotional intelligence (EQ) on the ethical behavior of the individual. The focus is on the individuals working in the SME sector. A questionnaire survey was considered the most appropriate technique to conduct the research. The study is based on 1162 responses, collected from three countries (the Czech Republic, Hungary and Slovakia).
Purpose of the article: The aim of this article is to examine the relationship between knowledge sharing, ethics and emotional intelligence. Furthermore, nationality, gender, education, and the age of the respondents influencing EQ are also examined. The additional goal is to explore the factors that influence employee behavior.
Methods: We identified four hypotheses. To test these hypotheses, we used variance analysis and logistic regression. The AES scale was chosen to assess EQ, which consisted of 33 items. The results obtained are compared with the opinion of SME owners resulting from structured interviews.
Findings & value added: About 20% of enterprises are not using any motivation tool to initiate knowledge sharing of their employees. The most common (47.2%) reason for silencing knowledge ? the lack of appreciation ? did not appear among the answer of company owners. According to the employee perceptions, gender has impact on the level of emotional intelligence, while nationality, education and age group have no impact on the EQ. SME owners do not address much attention to gender. The occurrence of unethical behavior does not depend on the size of the enterprise. According to employee opinion, the EQ has positive impact on knowledge sharing, while it is not affected by ethics. The majority of owners also agreed with the positive impact of EQ. The attitude of employees and owners differ in different aspects. The results have shown that gender plays an influential role in EQ. The research of this complex problem laid down the empirical foundations for the V4 countries
Demand forecasting: an alternative approach based on technical indicator Pbands
No full textResearch background: Demand forecasting helps companies to anticipate purchases and plan the delivery or production. In order to face this complex problem, many statistical methods, artificial intelligence-based methods, and hybrid methods are currently being developed. However, all these methods have similar problematic issues, including the complexity, long computing time, and the need for high computing performance of the IT infrastructure.
Purpose of the article: This study aims to verify and evaluate the possibility of using Google Trends data for poetry book demand forecasting and compare the results of the application of the statistical methods, neural networks, and a hybrid model versus the alternative possibility of using technical analysis methods to achieve immediate and accessible forecasting. Specifically, it aims to verify the possibility of immediate demand forecasting based on an alternative approach using Pbands technical indicator for poetry books in the European Quartet countries.
Methods: The study performs the demand forecasting based on the technical analysis of the Google Trends data search in case of the keyword poetry in the European Quartet countries by several statistical methods, including the commonly used ETS statistical methods, ARIMA method, ARFIMA method, BATS method based on the combination of the Cox-Box transformation model and ARMA, artificial neural networks, the Theta model, a hybrid model, and an alternative approach of forecasting using Pbands indicator. The study uses MAPE and RMSE approaches to measure the accuracy.
Findings & value added: Although most currently available demand prediction models are either slow or complex, the entrepreneurial practice requires fast, simple, and accurate ones. The study results show that the alternative Pbands approach is easily applicable and can predict short-term demand changes. Due to its simplicity, the Pbands method is suitable and convenient to monitor short-term data describing the demand. Demand prediction methods based on technical indicators represent a new approach for demand forecasting. The application of these technical indicators could be a further forecasting models research direction. The future of theoretical research in forecasting should be devoted mainly to simplifying and speeding up. Creating an automated model based on primary data parameters and easily interpretable results is a challenge for further research
