The present article examines the overall use of renewable energy among the European leaders and Poland’s place in such statistics. It also shows the potential in use of the so–called: “green energy” and its positive influence on the local and global ecosystem. The article shows how important it is to abandon the use of fossil energy sources are creating a negative ecosystem during the extraction and their use. According to the author, the production and use of biogas fuel is an alternative. The production of biogas is not only related to energy production, but it also improves the situation of materials management of green waste, waste from agriculture and plants treatment waste which are widely underrated. The use of these wastes in biogas production allows not only the neutralization of their impact on the environment but it also creates great opportunities in the heat and electricity production. Further, the article features numerous tables and graphs that show the great potential in the production and utilization of biogas as an alternative fuel in Poland and other countries with similar resource–energy potential. Another goal of this article is to debunk the theory that the process of methane fermentation in agricultural biogas plants produces odour which in fact is due to using outdated technology. The conclusions clearly indicate the usability of this type of investment and simultaneously reinforce the belief that the proper environmental policy of the state and local governments –understood as an eco–friendly regulation– gives a chance for a clean environment and economic growth potential.

Solar energy is the most important green energy source that may be used to address the problems caused by conventional energy sources. The research in this paper aims to evaluate the solar energy potential of M'Sila, an Algerian internal region, and to determine which technology, among those currently available on the market, is adequate for harnessing that potential for electricity production (PV and CSP). This assessment was based on data (daily temperature and daily solar irradiation) collected at M'Sila weather station for one year and from the NASA site for 34 years from 1984 to 2017. These data were treated with excel 2016 software to determine the total horizontal, diffuse and direct normal solar irradiation. During the study period, the total solar irradiation falling on a horizontal surface in M'Sila (GHI) was estimated to be 1.79 MWh/m2/year. The diffuse solar irradiation incident on a horizontal surface (DHI) and direct normal irradiation, respectively, were estimated to be 594.88 kWh/m2/year, 2117.93 kWh/m2/year. M'Sila is a favourable land for the installation of concentrating solar power plants and photovoltaic panels due to its significant potential energy. The parabolic trough system is recommended. While polycrystalline PV modules should be promoted and installed in M'Sila.

In June 2008, the U.S. Supreme Court ruled that the Second Amendment to the U.S. Constitution guarantees an individual the right to keep and bear arms. Two years later, this decision was also made applicable to state and local governments. Today, seven U.S. states have provisions allowing the carrying of concealed weapons on their public senior high school campuses. This article, introduced by a brief comment on the Second Amendment’s legal and academic history, traces several recent developments of legal change. It discusses relevant arguments and attitudes towards guns on campus, and explores issues of future concern for public colleges and universities within the realm of firearms and campus safety.

The COVID-19 pandemic situation threatens the health of people globally, especially adolescents facing mental problems such as depression, anxiety, and obsessive-compulsive disorder due to constant COVID-19 stress. The present study aimed to provide basic data highlighting the need to alleviate COVID-19 stress among adolescents by promoting physical activity participation and strengthening self-concept clarity (SCC). To examine the relationships among participation in physical activity, SCC, and COVID-19 stress in pandemic-like conditions, the study was conducted on middle and high school students aged 14 to 19 and an online survey was conducted on 1046 Korean adolescents (521 male and 525 female students in the preliminary survey and main survey). Frequency, reliability, confirmatory factor, descriptive, and path analyses were performed using SPSS and AMOS 18.0. Participation in physical activity exerted a positive effect on SCC (p < 0.001) as well as a negative effect on COVID-19 stress (p = 0.031). Our findings also indicated that SCC exerted a negative effect on COVID-19 stress (p < 0.001). Regular participation in physical activity and strong SCC are also fundamental elements for alleviating COVID-19 stress. Given these results, state and local governments and educational institutions should encourage youth to participate in sports by suggesting policies, providing guidelines, and offering education. Such information may allow adolescents to endure and overcome COVID-19 stress during this critical period of life.

State and local governments frequently invest in policies aimed at stimulating the growth of new industries, but studies of industrial policy and related economic development initiatives cast doubt on their effectiveness. This article examines the role of state-level industrial policies in contributing to the different economic trajectories of two U.S. metro areas—Pittsburgh, Pennsylvania, and Cleveland, Ohio—as they adapted to the decline of their legacy industries. Comparative case studies show that industrial policies in Pittsburgh, which empowered research universities as local economic leaders, contributed to the transformation of the local economy. In Cleveland, by contrast, state industrial policies invested in making incremental improvements, particularly in legacy sectors. The article concludes that by empowering new local economic actors—such as universities—industrial policies can foment political change that enables structural economic change to follow.
