Ensiling Safflower (\u3ci\u3eCarthamus Tinctorius\u3c/i\u3e) As an Alternative Winter Forage Crop in Israel

Israel is a subtropical country in which the rainy season is in winter, with frequent droughts. Wheat is the major winter forage crop in Israel, along with legumes as rotation crops. Alternative forage crops are sought that would be suitable for semi-arid areas. Safflower (Carthamus tinctorius) is usually grown as a source for oil and pigments but spineless cultivars could be used as fodder. Leshem et al. (2001) reported DM yields up to 22 t/ha and high DM digestibility when used for heifers. When safflower silage substituted maize and wheat silage in the rations of lactating cows, milk yields and milk fat were similar in the two groups (Landau et al., 2004). Safflower was preserved satisfactorily by ensiling in mini-silos (Weinberg et al., 2002). However, on some farm scale trials, safflower silages spoiled upon aerobic exposure. The objective of the current experiments was to further study the ensiling characteristics of safflower

Technology entrepreneurship as a factor of sustainable energy in smart cities

The implementation of intelligent engineering infrastructure in cities necessitates the involvement of a large number of various innovative organizations. The experience of pioneer smart cities and global companies that are developing smart technologies shows that the key role in that process is played by technology entrepreneurs, i.e., a community of innovators who are capable of rapidly creating breakthrough solutions, launching them into the market, adopting and commercializing them. This study analyzes the theoretical features and current essential tasks of tech entrepreneurship as a business phenomenon and ways and means for technology entrepreneurship by corporations and independent start-ups. Exploring the case of the energy sector in smart cities which presents a growing market for technology solutions, the authors reveal the structure of the main segments of technology entrepreneurship, including electric vehicles and charging infrastructure, smart metering, telemetering, demand side management, distributed generation and micro-grids. Examples are described of tech entrepreneurship projects that were implemented by energy and telecom companies with the purpose of making urban energy smarter and more sustainable. © 2020 WIT Press.The work was supported by Act 211 of the Government of the Russian Federation, contract No. 02.A03.21.0006

The article describes the key trends in education for the IT and radio electronics sectors, considers the comparative analysis of approaches to organization of scientific and educational activities in 30 foreign and domestic universities leading in subject ratings of QS Computer Science & Information Systems and Engineering – Electrical & Electronic. Characteristics of the trends are: • close and constantly increasing integration of educational and scientific fields of activity, which is reflected in the emergence of interdisciplinary educational programs, linking the educational process to research in breakthrough areas of knowledge and the formation of specific university ecosystems aimed at leadership in specific technologies; • the variety of forms of organization of the educational process, the orientation towards modularity, individuality and continuity, which are actively used in the promotion of educational services; • the general backlog of Russian universities from IT practice and expectations of the real sector. The research methodology included analysis of the content and models for the implementation of educational products, expert opinions on the requirements for the formation of IT professionals. As a result, disparities between current industry trends, the current situation in education and demands of the real sector were defined. In the context of the example of a number of master’s programs developed at the Institute of Radioelectronics and Information Technologies of the Ural Federal University, a mechanism for integrating science, education and consulting in order to develop highly-demanded interdisciplinary educational products has been demonstrated. The results of the research can be used by domestic and foreign universities working in IT-segments, to increase competitiveness and implement strategic scientific and educational initiatives.В статье рассмотрены ключевые тренды в образовании для отраслей IT и радиоэлектроники, проведен сравнительный анализ подходов к организации научно-образовательной деятельности в 30 зарубежных и отечественных университетах, лидирующих в предметных рейтингах QS Computer Science & Information Systems и Engineering – Electrical&Electronic.

Identity construction in massively multiplyer online games

This thesis examines the ways of how different elements of identity are performed in massively multiplayer online games. It tries to find patterns in identity construction through observation of features, such as gender, age, race, ethnicity, status and religion and how individuals interact with each other. The aim is to explore the premise that because online games provide endless opportunities for identity performance, and thus these identities might have little to do with reality and the offline world. In order to analyze identities online, a number of key topics are covered. These include identity, performativity of identity, online games and players behavior online. Cross-disciplinary theoretical approach is used to attack the problem. Several identity theories are overviewed (Boellstorff, 2008, 2012; Deterding, Waltz, 2012; Jenkins, 2004; Gilchrist et al. 2015; Wetherell, 2015; Goffman, 1959, 1961a; Appelrouth & Desfor, 2008; Crenshaw, 1989). Here identity is understood as an action - individual’s reaction to the society and as a process. Next, performativity of identity is discussed. Special attention is given to the deeply rooted performance discourse in games (Butler, 1990, 1997, 1999; Deterding, Waltz, 2012; Schechner, 2006; Brooks, 2011; Turner, 1982). Finally, key issues on identity performing online are discussed. Those include interconnectivity of offline and online identity, and how they might correlate (Boellstorff, 2008; Horns, Miller 2012; Kozinets, 2011; McGonigal 2012; Thomas 2007; Nakamura, 2002; Sarkeesian, 2012). The methodology used for collecting and analyzing the data draws from netnography, a sub-discipline of online ethnography and digital anthropology, which allows observing online games as a spectacle (Kozinets, 2011; Boellstorff, 2008; Boellstorff et al. 2012). Massively multiplayer online games provide a good possibility to have a large human sample for performance, games, sociological and cultural studies. Online communities of one such game, Clash of Clans, are observed in the game environment and at forums, where players are interacting with each other through written communication over an extended period of time. Number of observations on how age, status, gender and other elements of identity are performed online are recorded. The examples of online conversations are documented and analyzed and parts of the collected data are presented in the paper. Key findings show that individuals demonstrate their feelings and opinions stronger than in offline setting, since online world assumes less moderation and social constraints. However, even though there is a certain degree of freedom online, it is used sparingly. Certain identity experiments are happening online, for example individuals are trying to play a game as a player of an opposite sex. However, on a verbal level, individuals tend to be more truth to their opinions and beliefs (Schau and Gilly, 2003; Whitty, 2004). A strong interconnectivity of online and offline identities in a digital age is found, so the basic hypothesis is contested. Currently hundreds of millions of people of all age groups are the participants of the massively multiplayer online games daily. Players start to take their online identities seriously and their online life starts to affect offline life, cultural, social norms and beliefs. And since we understand that online and offline identity is affecting each other on a deeper level than ever before, research in online massive multiplayer online games should be carried further. The field of game studies and performativity online should not be overlooked. The way identities are presented online mirror identity presentation in offline world closely
