Abstract This paper offers a brief overview of the research of ICT utilization and benefits of its usage. The results of several important studies conducted worldwide are presented. One of them is a study by the World Economic Forum that we use as the basis of our research. This study covers 134 countries, NRI (Network Readiness Index) is used as a parameter to distinguish the readiness of different countries to adopt ICT. NRI consists of 68 indicators that are organized into three groups. Each group describes one of the three main factors crucial for effective utilization of ICT: Environment, Readiness and Usage. The observed countries are divided into four groups (leaders, followers, league III and league IV) and classification by a decision tree is conducted. The decision tree method is applied to each of the three main factors and the results are presented by means of F1 measure.

Abstract Environmental justice is a normative framework for the analysis of environmental impacts on the wellbeing of individuals and social groups. According to the framework, the deprived social groups and ethnic minorities are often more exposed to environmental risks and hazards due to their disadvantaged situation, and due to the lack of representation and political power. To manage the impacts of injustices and to include the citizen in the decision-making processes, proper information is needed on local attitudes and decision-making processes. Therefore, this study sought to (i) identify the main factors shaping the attitudes towards environmental injustices and (ii) to analyse the attitudes and perception of the various social groups and (iii) to identify the main factors which are shaping the attitudes and actions of those who were affected by the floods of 2001 and 2010 through the use of decision tree method. The data for the predictive model was acquired from a questionnaire survey conducted in two disadvantaged and flood-hit Hungarian regions. Based on the survey data, a principal component analysis (PCA) was conducted, which resulted in three principal components; fear, social change, and change in the built environment. The study focused only on the elements of the “fear principal component”, due to the decision tree tool homogenous groups identified in relation to this component. Our analysis showed that ethnicity has a determinative role in the emergence and the level of fear from floods; the Roma respondents expressed a significantly higher level of fear than others.

The subject of this paper is metamodeling and its application in the field of scientific research. The main goal is to explore the possibilities of integration of two methods: questionnaires and decision trees. The questionnaire method was established as one of the methods for data collecting, while the decision tree method represents an alternative way of presenting and analyzing decision making situations. These two methods are not completely independent, but on the contrary, there is a strong natural bond between them. Therefore, the result reveals a common meta-model that over common concepts and with the use of metamodeling connects the methods: questionnaires and decision trees. The obtained results can be used to create a CASE tool or create repository that can be suitable for exchange between different systems. The proposed meta-model is not necessarily the final product. It could be further developed by adding more entities that will keep some other data.

Medical imaging techniques like fluorodeoxyglucose positron emission tomography (FDG-PET) have been used to aid in the differential diagnosis of neurodegenerative brain diseases. In this study, the objective is to classify FDG-PET brain scans of subjects with Parkinsonian syndromes (Parkinson’s disease, multiple system atrophy, and progressive supranuclear palsy) compared to healthy controls. The scaled subprofile model/principal component analysis (SSM/PCA) method was applied to FDG-PET brain image data to obtain covariance patterns and corresponding subject scores. The latter were used as features for supervised classification by the C4.5 decision tree method. Leave-one-out cross validation was applied to determine classifier performance. We carried out a comparison with other types of classifiers. The big advantage of decision tree classification is that the results are easy to understand by humans. A visual representation of decision trees strongly supports the interpretation process, which is very important in the context of medical diagnosis. Further improvements are suggested based on enlarging the number of the training data, enhancing the decision tree method by bagging, and adding additional features based on (f)MRI data.

Russian economy has reached the low level of inflation, but economic growth has not accelerated. Moreover, according to official forecasts, in the following years it will still be low. The article concludes that domestic demand, which is one of the main factors of growth, is significantly constrained by monetary, budgetary and fiscal spheres. The situation in the Russian economy is still hampered by the decline of the world economic growth. The prospects of financial markets are highly uncertain. This increases the possibility of crisis in the world. Leading countries widely use non-traditional measures to support their economies in the similar environment. In the world economy as well as in Russia a principally new combination of factors has emerged, which create specific features of economic growth. It requires special set of measures to stimulate such growth. The article proves that Russian regulators have large unused potential to stimulate growth. It includes monetization, long-money creation, budget and tax stimuli. It is important that the instruments, which will be used, should be based on domestic mechanisms. This will strengthen financial basis of the economy and may encourage economic growth. Some specific suggestions as to their use are made.

Climate change is a financial factor that carries with it risks and opportunities for companies. To support boards of directors of companies belonging to all jurisdictions, the World Economic Forum issued in January 2019 eight Principlescontaining both theoretical and practical provisions on: climate accountability, competence, governance, management, disclosure and dialogue. The paper analyses each Principle to understand scope and managerial consequences for boards and to evaluate whether the legal distinctions, among the various jurisdictions, may undermine the application of the Principles or, by contrast, despite the differences the Principles may be a useful and effective guidance to drive boards' of directors' conduct around the world in handling climate change challenges. Five jurisdictions are taken into consideration for this comparative analysis: Europe (and UK), US, Australia, South Africa and Canada. The conclusion is that the WEF Principles, as soft law, is the best possible instrument to address boards of directors of worldwide companies, harmonise their conduct and effectively help facing such global emergency.

The Impact

The article describes the situation of gender equality in Ukraine and in the world during the last 5 years, identifies the leading countries in moving towards gender equality in various fields of life by analyzing the indicators of the Global Gender Gap Report of the World Economic Forum. These indicators include: Economic Participation and Opportunity, Educational Attainment, Health and Survival, Political Empowerment, which are the part of a single index that determines the position of countries in the overall ranking. Based on the results of this analysis, Ukraine has improved value of gender equality index, although in the overall ranking of countries Ukraine has lost its position and dropped 11 ranks lower than in 2014. This means that, among all the countries surveyed by the World Economic Forum, there are countries that are moving much faster towards gender equality than Ukraine. In addition, the article includes the investigation of the gender representation among the board members of 5 enterprises of Ukraine for 2014-2017, which represent the leading sectors of the Ukrainian economy. The dynamics of changes in the level of performance of these enterprises using the return on assets (ROA) indicator is analyzed, the relationship between the leadership of the enterprises and the value of the ROA indicator is graphically presented. The obtained results do not give a clear answer about the gender impact on the enterprise performance. The reason for this is a number of factors, such as: insufficient statistical sampling of enterprises; the selected performance indicator of enterprise activities does not fully reflect the impact of the gender factor on enterprise activities; the methodology used in the work needs improvements, or it is necessary to choose a totally new approach to the analysis of the investigated issue under study. Gender representation among board members and its impact on enterprise performance should be investigated further. Key words: gender, gender equality, enterprise board members, return on assets.
