Preheating of the engine is often used to facilitate the start of the internal combustion engine in winter, which provides an opportunity not only to increase the comfort of starting, but also to reduce exhaust emissions, increase engine life. That is why the choice of optimal heat storage materials, which on the one hand would have sufficient heat efficiency and on the other hand would satisfy the operational requirements regarding corrosion activity, etc., is an urgent problem. In particular, the barium octohydrate used in our studies is corrosive, although it has a high heat of phase transition heat. The media investigated the media that are ordinary working fluids for heat transfer during heat accumulation: antifreeze, antifreeze, water; heat-accumulating materials – paraffins and octohydrates, and as investigated in relation to corrosion of material steel St3 was considered. The working temperature range was used in the work. It was found that the corrosion rate of 3 mm per year in antifreeze and antifreeze environments requires the choice of anti-corrosion coating or the search for new material that will react.

Violence against women (VAW) continues to exist as a pervasive, structural,systematic, and institutionalized violation of women’s basic human rights (UNDivision of Advancement for Women, 2006). It cuts across the boundaries of age, race, class, education, and religion which affect women of all ages and all backgrounds in every corner of the world. Such violence is used to control and subjugate women by instilling a sense of insecurity that keeps them “bound to the home, economically exploited and socially suppressed” (Mathu, 2008, p. 65). It is estimated that one out of every five women worldwide will be abused during her lifetime with rates reaching up to 70 percent in some countries (WHO, 2005). Whether this abuse is perpetrated by the state and its agents, by family members, or even by strangers, VAW is closely related to the regulation of sexuality in a gender specific (patriarchal) manner. This regulation is, on the one hand, maintained through the implementation of strict cultural, communal, and religious norms, and on the other hand, through particular legal measures that sustain these norms. Therefore, religious institutions, the media, the family/tribe, cultural networks, and the legal system continually disciplinewomen’s sexuality and punish those women (and in some instances men) who have transgressed or allegedly contravened the social boundaries of ‘appropriateness’ as delineated by each society. Such women/men may include lesbians/gays, women who appear ‘too masculine’ or men who appear ‘too feminine,’ women who try to exercise their rights freely or men who do not assert their rights as ‘real men’ should, women/men who have been sexually assaulted or raped, and women/men who challenge male/older male authority.

This article examines how freedom of speech is framed in the media controversy surrounding the Australian rugby player Israel Folau’s April 2019 Instagram post. A content analysis and framing analysis of newspaper reportage reveals that the controversy has been largely discussed in terms of whether or not Folau’s speech was being curtailed and whether this curtailing indicates a broader, ideologically motivated censoriousness. This discussion is problematic in that it says little about the actual substance of Folau’s post. This article argues that debates surrounding freedom of speech such as the one involving Folau could and should be enriched by an engagement with ethical principles. This engagement is premised on a commitment to the free exchange of views, while acknowledging that ‘speech’ is not always inherently beneficial for democracy, nor worth defending.

AbstractDuring the Soviet period, the media served as one of the main propagandist tools of the authoritarian regime, using a standardized and monotype media system across the Soviet Republics. After the collapse of the Soviet Union, 15 countries became independent. The transition from Soviet communism to capitalism has led to the reconstruction of economic, socio-cultural, and political systems. One of the most affected institutions in post-Soviet countries was the media. Media have played a supportive role during rough times, when there was, on the one hand, the struggle for liberation and sovereignty, and, on the other hand, the need for nation building. It has been almost 30 years since the Soviet Republics achieved independence, yet the media have not been freed from political control and continue to serve as ideological apparatuses of authoritarian regimes in post-Soviet countries. Freedom of speech and independent media are still under threat. The current study focuses on media use in Azerbaijan, one of the under-researched post-Soviet countries. The interviews for this study were conducted with 40 participants living in Nakhichevan and Baku. In-depth, semi-structured interview techniques were used as research method. Findings are discussed under six main themes in the conclusion.

AbstractFrom a theoretical and empirical linguistic point of view, this paper emphasizes the importance of the relationship between populism and the media. The aim of this article is to explore the language use of the Spanish right wing populism party Vox on the basis of its multimodal postings on the social network Instagram. For the analysis of their Instagram account, a suitable multimodal discourse analysis (MDA) provides a variety of methods and allows a theoretical integration into constructivism. A hashtag-analysis reveals that Vox’s ideology consists of a nativist and ethnocentric nationalism on the one hand and conservatism on the other. With a topos analysis, the linguistic realisations of these core elements are illustrated with two case studies.

This paper aims to investigate the language used by newspapers in post-revolutionary Iran. More precisely, the paper sets out to analyze how such a language is deployed to represent relevant hegemonic ideologies. The approach adopted for this purpose draws inspiration mainly from critical linguistics, where it is hypothesized that, as far as the pertinent metadiscourse goes, media genres serve to activate and perpetuate social power relations. In keeping with this theoretical stance, the paper argues that socially constructed texts can be said to perform two complementary functions; on the one hand, they shed light on the realities experienced in social life; on the other, they reveal such aspects of those realities as are constructed through the use of language. It is thus in this context that the media language used in the post-revolutionary Iran lends itself to analytical investigation, where the available data reveal the co-existence of three competing discourse processes of ‘Islamization’, ‘Iranian Nationalism’ and ‘Western liberalism’, relating to the third stage development of post-revolutionary Iran.

The paper makes an attempt to resolve two conceptual mingling: (a) the mingling of the two interpretations of the concept of orderedness applied in statistical thermodynamics and in symmetrology, and (b) the mingling of two interpretations of evolution applied in global and local processes. In conclusion, it formulates a new interpretation on the relation of the emergence of new material qualities in selforganizing processes on the one hand, and the evolution of the universe, on the other. The process of evolution is a sequence of emergence of new material qualities by self-organization processes, which happen in negligible small segments of the universe. Although thermodynamics looks at the universe as a closed (isolated) system, this holds for its outside boundaries only, while the universe has many subsystems inside, which are not isolated (closed), since they are in a permanent exchange of matter, energy, etc. with their environment (with the rest of the universe) through their open boundaries. Any ";;emergence";; takes place, i.e., all new qualities come into being just in these small open segments of the universe. The conditions to apply the second law of thermodynamics are not present here. Therefore, global evolution of the universe is the consequence of local symmetry decreases, local decreases of orderedness, and possible local decreases of entropy.

Although graffiti is a well-known phenomenon of street art, there is still no single point of view on this phenomenon (even if it is considered art at all). Both the essence and the manifestations of graffiti remain a matter of debate - there are dozens of different classifications, that they are based on different characteristics. However, the phenomenon has rarely attracted attention from the point of view of semiotics, though it is the semiotic reading of graffiti that makes it possible to understand its nature more deeply. Due to semiotics we could create an integrative classification, which would combine stylistics and subject matter into one system. The article made exactly such an attempt –providing of the semiotic classification of graffiti, based on Ch. Peirce’s classification of semiotic signs. Graffiti is a sign, because it has a material shell of the latter, a marked object and rules of interpretation. It functions within the subculture and signifies the individual's desire to escape from the deterministic nature of urban life (J. Baudrillard). It is a culture of the semiosphere, which continuously gives rise to new connotations and, accordingly, generates new receptions. An important component of graffiti interpretation is the cultural code; it is not read outside the field of conventionality, cultural context. Decoding of graffiti can occur in three ways. From our point of view, it is appropriate to use S. Hall’sclassification. He suggested a scheme for "decrypting" messages in the media, however, in our opinion, his scheme works for any communicative act (including graffiti). He distinguished dominant ("dominant-hegemonic"), oppositional ("oppositional") and negotiated ("negotiated") decoding. In the graffiti situation, oppositional decoding prevails among ordinary recipients (passers-by). U. Eco called this type aberrant, because it provides "decryption" of text with a different code than the one it was created for. Authors of graffiti themselves are often not fully aware of what they createalso. Modern writers use techniques of op-art, Dadaism, surrealism, etc., without being very oriented in all these directions. When graffiti combines different types of art (for example, the combination of painting with literature), it takes into account the features of inter-semiotic translation, which makes the decoding situation even more complicated. We offercreating a semioticclassificationofgraffiti, that might be based on Ch. Peirce’s classification of semiotic signs, whichdistinguishthesigns-copies, signs-indexes, signs-symbols. It could help the essence of graffiti and decode them.

The letter of the Holy Father John Paul II written in Rome in 1987, in the tenth year of His pontificate, on December 4th, on the day of memorial of Saint John Damascene, the doctor of the Church, on the Twelfth Centenary of finishing the controversy over the icon, is of great importance for the Pope’s program of ecumenism. The Holy Father indicated various directions of the dialogue, however, the one of the utmost importance concerned the agreement with the Orthodox Church, which was confirmed in the letters and in His other documents quoted in this paper. The image used to be essential for religious practice, for illustrating the word of prayer and of the song, in order to preserve the tradition of the Church. The strict prohibition introduced by the iconoclasm depreciated not only the artistic tradition of paintings but also the basic dogmas of Christ’s Incarnation and the one which introduced Virgin Mary as the Theotokos (the God-bearer). The ban constituted a threat not only for the icons but also for the Christian faith. In His Letter, the Pope underlined the important role of the Second Council of Nicaea which reintroduced icons and maintained and deepened the meaning of the cult in the faith of believers. Furthermore, the Holy Father indicated the connection with the Second Vatican Council in understanding the function and form of images in contemporary Church. Contemporary trends are overwhelmed by the impotence of the spiritual expression of sacral art, which is a great concern for the Pope. The Letter is, therefore, a dramatic warning of the threats for religious art in contemporary time, expressed by the Holy Father with these words: ‘The rediscovery of the Christian icon will also help in raising the awareness of the urgency of reacting against the depersonalizing and at times degrading effects of the many images that condition our lives in advertisements and the media.’ (DS, 11).

Shock content as a manipulative component of conflict discourseDifficult socio-political situation in Ukraine creates specific media discourse, which in turn gives rise to a number of phenomena, connected to information war categories, war of meanings, hate speech etc. Active entry of military issues into web news content affects traditional approach to the media-text drafting. The report examines the trends of shock visual content and its announcement in the web headlines. The influence of the content emotionalization, which is one of the common features for conflict discourse, not only on text style, but also on features of page making, selection and use of photo illustrations, headline creation, is studied. The material covering military developments usually involve deaths, injuries, loss, destruction of settlements as a result of hostilities, that is, they focus on information on suffering of both military and civilians. This results in stronger integration of shock visual content into the news, which in turn may be used as manipulation and propaganda tool. On the one hand it is used to demonstrate crimes of the enemy, on the other — as an evidence of Ukrainian military success. From the point of view of ethic and humanism the justification of such tactic is doubtful in both cases. However, the study shows that open image of death, blood, injuries in the materials and the announcement of such content in headlines are the cause of high popularity of such publications, and this mainstreams the problem of dehumanizing impact both on material’s subjects and on media audience.

Ketika mempelajari bahasa Jepang di sekolah, aspek dasar yang harus dipelajari siswa adalah huruf Jepang. Dalam sistem penulisan, bahasa Jepang memiliki empat huruf, yaitu huruf kanji, hiragana, katakana, dan roomaji. Tetapi sebelum tahap belajar huruf kanji, terlebih dahulu siswa mempelajari huruf hiragana dan katakana yang biasa disebut huruf kana. Huruf kana terdiri atas 96 huruf dimana huruf hiragana dan huruf katakana tersebut bentuknya mirip. Hal ini menyebabkan siswa kesulitan untuk mempelajari huruf kana. Oleh karena itu, diperlukan suatu media untuk mempermudah pembelajar mempelajari huruf kana. Salah satu media yang dapat digunakan adalah media permainan. Dalam penelitian ini, media permainan yang digunakan adalah media permainan sudoku yang sudah di modifikasi. Tujuan dari penelitian ini adalah untuk mengetahui kemampuan siswa dalam pembelajaran huruf kana, sebelum dan sesudah menggunakan media permainan sudoku. Selain itu, penelitian ini bertujuan untuk menganalisis pengaruh penggunaan media permainan sudoku terhadap pembelajaran huruf kana, dan untuk mengetahui respon siswa terhadap penggunaan media permainan sudoku. Penelitian ini menggunakan metode experimen quasi dengan desain eksperimen yaitu one group pre-test - post-test. Sampel penelitian adalah anggota Japanese Club sebanyak 20 orang yang diambil dari populasi SMP Laboratorium Percontohan UPI Bandung. Instrumen yang digunakan adalah tes, angket dan obsevasi. Berdasarkan hasil analisis data, nilai t hitung sebesar 6.53. Nilai t tabel sebesar 2.09 pada taraf signifikansi 5% dan 2.86 pada taraf signifikansi 1%. Dengan demikian, diperoleh hasil t hitung lebih besar dibandingkan nilai t tabel pada taraf signifikansi 5% (6.53 > 2.09). Hal ini menunjukkan bahwa pengguanaan media permainan sudoku dalam pembelajaran huruf kana sangat efektif. Selain itu, berdasarkan hasil analisis data angket, responden memberikan tanggapan yang positif terhadap penggunaan media permainan sudoku yaitu menarik, dan mudah diikuti. When studying Japanese at school, basic aspects must study is the Japanese letter. In its writing system, Japanese has four letters, namely kanji, hiragana, katakana, and roomaji. Before the stage of kanji learning, firstly, students have to learn hiragana and katakana which are commonly called kana. Kana, composed of 96 letters where the letter of the hiragana and katakana are barely different. This causes difficulties for students to learn kana. Therefore, we need a media to facilitate learners to learn kana. One medium that can be used are game as the learning media. This study, the media used is a sudoku game that has been modified. The purpose of this study is to acknowledge students’ ability in learning kana, before and after using the sudoku game as a media. In addition, this study also aims to analyze the influence of sudoku game usage as the media in learning kana Letters, and to find out the students' response to the use of sudoku game as a media. This study uses a quasi experiment method with the one group pre-test - post-test as experiment design. Samples were 20 students from Japanese Club members who were taken from a population of SMP Laboratorum Percontohan UPI Bandung. The instrument used was test, questionnaire and observation. Based on the data analysis, the t value at 6.53. T table at 2.09 on a significance level of 5% and 2.86 at 1% significance level. Thus, the results obtained that t value is greater than t table at a significance level of 5% (6.53> 2.09). This shows that the usage of sudoku game as media is a very effective in learning kana. In addition, based on data analysis of the questionnaire, the respondents gave a positive response to the use of media sudoku game that are attractive, and easy to follow
