Who is a gamer? What kind of people are perceived to be gamers? And finally – who perceives themselves as a gamer? In this article the authors attempt to answer these three questions from a multinational perspective. Background. Games are nowadays one of the most frequently encountered forms of entertainment and constitute an ever-increasing part of many people’s day-to-day lives. With the rising popularity of video games, there is a need to conduct a research concerning gamer identity and to find out who perceives themselves as a gamer. The aim of this study is to compare the results of the survey conducted in two different countries to better understand the characteristics of players that self-identified as gamers. Methods. The quantitative study was conducted in two countries – Poland and the United States – in order to research gamer identity. The questionnaire consisted of questions about the self-identification as a gamer, time spent playing video games, types of games played, and the platforms used. It was conducted among 223 students who play video games. Results. The results show that there are both similarities and differences in the meaning of gamer identity between Poland and the United States. People who consider themselves gamers generally spend more time playing games than non-gamers regardless of the country. However, some differences can be spotted between Poland and the U.S. concerning among others types of games played, used platforms or different styles of playing video games. Limitations and further research. The main problem in the study was the limited age range in the sample. In the future it seems valuable to include people of different age groups to broaden the study of self-identified gamer identity.
Railway transit forms the backbone of sustainable transportation systems, which are necessary to limit the effects of global warming. In this paper, the authors seek to determine whether there is a statistically significant difference in energy consumption between distinct railway vehicle types. Firstly, the energy consumption measurement methods in the railway transportation sector are described and compared to each other in respect to precision and cost. Secondly, the use of energy consumption as a criterion in rolling stock tenders with the associated norm is analysed, particularly with regard to the life-cycle cost of railway vehicles. In the next part real life data on energy consumption of six distinct passenger electrical railway vehicle types is presented and analysed in order to compare the efficiency of different types of rolling stock. The differences in energy efficiency between rolling stock types may be used to improve the procurement process ensuring train operating companies obtain less energy-consuming vehicles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
