1. Prices of conventional and renewable energy as determinants of sustainable and secure energy development : regression model analysisSandi Knez, Goran Šimić, Anica Milovanović, Sofia Starikova, Franc Željko Županič, 2022, original scientific article Abstract: Background
The prices of energy resources are important determinants of sustainable energy development, yet associated with significant unknowns. The estimates of the impact of prices of energy products in the domestic market (for domestic consumers) are rare—hence the importance and novelty of this research. Therefore, the main goal of the paper is to assess the impact of domestic prices of gasoline, gas, coal, and solar energy on sustainable and secure energy future.
Methods
The research includes 14 countries (of which 7 are developed and 7 are developing countries) and a period of 5 years (2014–2018). The model also includes discrete variables: level of development (developing or developed), and the fact as to whether the country is an energy exporter or not. For the purposes of analysis, the following elements were used: Panel Data Analysis, Linear regression (with random and fixed effects), Durbin–Wu–Hausman test, and Honda test, with the use of R-studio software for statistical computing.
Results
The research showed that the biggest negative impact on energy sustainability was recorded by an increase in the price of coal and the smallest one by an increase in the price of solar energy. An increase in the price of gasoline has a positive impact, while an increase in the price of gas has no impact. The basic methodological result showed that the fixed effects linear model is more accurate than the random effect model.
Conclusions
The results of the paper, important as a sustainable energy policy recommendation, showed that the impact of changes in energy product prices is significantly greater in developing countries, but that the status of the country as an energy exporter has no significance. In addition, the paper points to the need to intensify the research on the assessment of the impact of energy product prices for domestic consumers on their ability to pay that price, because with a certain (so far undefined) increase in energy product prices, a certain group of domestic consumers moves into a category that is not in line with sustainable energy development and is extremely undesirable in every respect—energy poverty.

2. A system dynamics model for improving primary education enrollment in a developing countryChandra Sekhar Pedamallu, Linet Ozdamar, LS Ganesh, Gerhard-Wilhelm Weber, Erik Kropat, 2010, original scientific article Abstract: The system dynamics approach is a holistic way of solving problems in real-time scenarios. This is a powerful methodology and computer simulation modeling technique for framing, analyzing, and discussing complex issues and problems. System dynamics modeling is often the background of a systemic thinking approach and has become a management and organizational development paradigm. This paper proposes a system dynamics approach for studying the importance of infrastructure facilities on the quality of primary education system in a developing nation. The model is built using the Cross Impact Analysis (CIA) method of relating entities and attributes relevant to the primary education system in any given community. The CIA model enables us to predict the effects of infrastructural facilities on the community's access of primary education. This may support policy makers to take more effective actions in campaigns that attempt to improve literacy.

4. Factors that impact internet use and are sensitive to income : cross-country empirical evidenceDijana Močnik, 2010, original scientific article Abstract: This paper examines information and communication technology (ICT) and socioeconomic indicators associated with Internet use based on income level across countries. Although some literature deals with cross-country indicatorsof Internet use, no known study quantitatively examines which indicators are superior or how they differ across countries with different income level. We extract factors with the most important indicators and evaluate their impact on Internet use for four income groups: low, lower middle, upper middle, and high. The results show that Internet use can be stimulated by educated people, available computers, telecommunications connections and increasing income per capita. However, prices of telecommunications services, international trade, investment, population density, unemployment rate or GDP growth rate do not affect Internet use.

5. National transfer accounts for Slovenia : doctoral dissertationJože Sambt, 2009, doctoral dissertation Abstract: In the early years of life human beings have to rely on transfers from their parents and other parts of society to satisfy their basic needs, receive health care, education etc. At the very beginning these transfers are crucial for survival and they determine the quality of their life and success of their future development. In addition in old age transfers in the form of pension, health care, long-term care etc. significantly determine the wellbeing of individuals. In those ages individuals are economically dependent, their consumption exceeding their production. The consumption surplus or ‘lifecycle deficit’ has to be financed through economic flows across age. ...
