Potassium Influx

Abscisic acid at a concentration of 10 mg/liter inhibits up to 79% of the potassium uptake of slices of expanding Vicia faba leaves in the dark, and up to 75% of the greater potassium influx occurring in the light. Abscisic acid has no effect on the potassium influx into tissue from non-expanding, mature leaves which consistently leak potassium into the media. The possible role of abscisic acid in ion movement within plant tissue is discussed.

Abscisic acid inhibits stomatal opening in isolated abaxial epidermal strips of Vicia faba. Kinetin, benzyladenine, and gibberellic acid, which can enhance stomatal apertures in intact leaves, are ineffective on isolated epidermal strips. Abscisic acid appears to act directly on the guard cells, rather than by influencing water potentials throughout the leaf.

The urgency of the researched problem is connected with the growing role of mass media in modern conditions leads to change of values and transformation of identity of the person. The active growth of the role of the media, their influence on the formation and development of personality leads to the concept of “media socialization” and immutation in the media. The aim of the study is to outline the possibilities of the process of media socialization in the context of immutation in the media. The methods of our research are: analysis of pedagogical, psychological, literature, synthesis, comparison, generalization. The article analyzes the views of domestic and foreign scientists on the problem of immutation in the media and the transformation of the information space. In the context of the mass nature of the immutation of society, the concept of “media socialization” becomes relevant, which is the basis for reducing the negative impact of the media on the individual.The author identifies the lack of a thorough study of the concept of “media socialization” in modern scientific thought. Thus, media socialization is associated with the transformation of traditional means of socialization, and is to assimilate and reproduce the social experience of mankind with the help of new media.The article analyzes the essence of the concepts “media space”, “mass media” and “immutation”. The influence of mass media on the formation and development of the modern personality is described in detail.The study concluded that it is necessary to form a media culture of the individual, to establish safe and effective interaction of young people with the modern media system, the formation of media awareness, media literacy and media competence in accordance with age and individual characteristics for successful media socialization. The role of state bodies in solving the problem of media socialization of the individual was also determined. It is determined that the process of formation of media culture in youth should take place at the level of traditional institutions of socialization of the individual.The author sees the prospect of further research in a detailed analysis and study of the potential of educational institutions as an institution and a means of counteracting the mass nature of the immutation of society.Key words: immutation, media socialization, mass media, media space, information.

Cartesian Fingerprints in Beckett's Imagination Dead Imagine

Limiting Case

The idea that Beckett investigates in his works the limits of the media he uses has been widely discussed. In this article I examine the fiction Imagination Dead Imagine as a limiting case in Beckett's exploration of limits at large and the limits of the media he uses in particular. Imagination Dead Imagine is shown to be the self-reflexive act of an artist who imaginatively explores the limits of that ultimate medium – the artist's imagination itself. My central aim is to show that various types of structural homologies (at several levels of abstraction) can be discerned between this poetic exploration of the limits of imagination and Cartesian thought. The homologies indicated here transcend what might be termed as ‘Cartesian typical topics’ (such as the mind-body dualism, the cogito, rationalism versus empiricism, etc.). The most important homologies that are indicated here are those existing between the role of imagination in Descartes' thought - an issue that until only a few decades ago was quite neglected, even by Cartesian scholars - and Beckett's perception of imagination. I suggest the use of these homologies as a tool for tracing possible sources of inspiration for Beckett's Imagination Dead Imagine.

The purpose of this research is to explain the importance of the student organizations and describe their efforts to improve the speaking skills of students at the Mahad Khalid Bin Al Waleed at the University of Muhammadiyah Mataram. This research uses the qualitative approach with the descriptive type. The result shows the student organizations play an important role based on their objectives and functions. The objectives are to help the foundation and all parties in the Ma'had develop the students’ potential and qualification, and to be the place for the students to share their problems and complaints, while the functions are as one of the media to develop students’ quality, both the members of the non-member, and as the good examples and pioneers of any good deeds. The efforts done by student organizations in improving speaking skills are such as by making activities that lead to improving students' speaking skills like sticking vocabularies in each class and Friday activities such as language game, Arabic debate and short lecture.

The article is devoted to the study of evaluative tools used in modern French media in order to form the media image of a representative of the political elite. The techniques used in the creation of a memorial media portrait of Jacques Chirac (1932—2019), President of France from 1995 to 2007 are considered. The research material was the most prestigious French print media of various political orientations, published in late September — early October 2019 in connection with the death of the ex-President of the French Republic. The relevance of the research topic is dictated by the close attention of modern linguistics to axiological phenomena, differently presented in different types of discursive practices. The novelty of the study is due to the appeal to the analysis of the complex of evaluation tools used in the French print media when characterizing the former leader of the state during the nation’s farewell period. The estimated potential of the title of the article and its influence on the formation of the estimated vector of the entire text of the publication are shown. A systematic analysis of the assessment expression means, reflected in the memorial media portrait of the politician, is given. The factors that influenced the peculiarities of their use in this type of media portrait are revealed.

An emerging global trend of brands advertising their products through LGBTIQ+ individuals and couples indicates growth of gender awareness across the globe. The media, through advertising, deconstructs homophobia and associated cultures through the use of LGBTIQ+s in commercials. This qualitative research paper centres the advancement of debates on human rights and social media as critical in the interaction between corporates and consumers. The Gillette, Chicken Licken‘s Soul Sisters and We the Brave advertisements were used to critically analyse how audiences react to the use of LGBTIQ+ characters and casts through comments posted on the brands‘ social media platforms. Further, the paper explored the role of social media in the mediation of significant gender issues such as homosexuality that are considered taboo to engage in. The paper used a qualitative approach. Using the digital ethnography method to observe comments and interactions from the chosen advertisement‘s online platforms, the paper employed queer and constructionist theories to deconstruct discourses around same-sex relations as used in commercials, especially in quasiconservative. The data used in the paper included thirty comments of the brands customers and audiences obtained from Twitter, Facebook and YouTube. The paper concludes there are positive development in human rights awareness as seen through advertisements and campaigns that use LGBTIQ+ communities in a positive light across the world.
