Dual nature of high-temperature electronic transport in layered perovskite-like cobaltites: exhaustive consideration of experimental features observed

Complex oxides with the general formula Pr1−xYxBaCo2−yNiyO6−δ (x = 0, 0.1, y = 0, 0.2) were successfully synthesized via combustion of organo-metallic precursors.

Electron Delocalization on the Silicon Nanoparticles Surface

The specific properties of tubular and fullerenlike silicon nanoparticles depend on theirs electronic structure, which is directly related to the surface geometry. Using density functional approach, a novel dual nature of the surface structure of silicon nanotubes which depends on the type of nanotube have been revevaled. The rippled form of the surface has shown to be a favorable one for (n, n) type structure and the most stable form for (n, 0) Si NT is the nanotube with a smooth-walled graphene-like surface. The phenomenon is explained by the relative position of the non-hybridized p orbitals on the surface.

Her Body Islanded” Corporeal Resistance in Margaret Atwood’s The Edible Woman

Marian MacAlpin, the protagonist of Margaret Atwood’s The Edible Woman, is a “marvellously normal” (Atwood 207) young woman. However, at one point—coinciding with the acceptance of her partner’s marriage proposal—something goes utterly wrong. Her body, in an act of revolt, refuses to accept more and more food; it becomes an increasingly independent, as if exterior entity. While trying to fight off this impenetrable rebellion, Marian comes to face social norms she is supposed to comply with as a woman, finding them indeed indigestible. Written in 1965 and published in 1969, The Edible Woman touches upon issues that are still relevant for the contemporary reader. This article examines Margaret Atwood’s novel within the framework indebted to the recent shift of feminist studies towards fragility: a notion that no longer has to entail mere passivity or surrender. Aiming at an exploration of the theme of a fragile corporeal protest, this article juxtaposes the revolt of Marian’s body with such tropes and categories as fluidity and containment, abjection, agency, and becoming in order to trace the dual nature of corporeal resistance presented in the novel.

Defining different types of assessment systems and assessment procedures in the context of historical development

Introduction. The authors investigate a wide range of assessment systems in modern education. They analyze and compare changes in educational assessment procedures, taking into account the periodization of their development and modern requirements and standards. The purpose of the article is to identify and clarify various types of assessment systems and assessment procedures in the context of historical development. Materials and Methods. This theoretical research includes analysis, comparison, and generalization of Russian and international studies on the development of assessment systems based on the concept of the historical and socio-cultural determination of education. The study follows systemic, learner-centered and activity-based approaches in order to present the dynamics of the development of educational assessment as a system comprising interconnected parts and socio-psychological factors. Results. The authors clarified the essence of the dual nature of educational assessment as a didactic and socio-psychological phenomenon. They described the relationship between assessment procedures and the quality of modern education. The study identified the main periods in the development of educational assessment based on the criteria for changing the requirements for the content of education, as well as changes in the assessment system regarding tasks, methods, forms of assessment, point scales and methods of motivation. The authors have developed and justified the historical periodization of educational assessment, which includes eight main stages. The main types of assessment including partial assessment, effective assessment, systemic assessment, standardized assessment, formative assessment, summative assessment, evaluation for management, and rating assessment have been identified and described. Conclusions. The article concludes that modern education implements eight main types of assessment, which have been developed in a historical context. At the same time, standardization of education is considered as the main trend in the formation of assessment systems.

Streben of the I as the Fundamental Form of Consciousness

This paper aims to show that Fichte’s concept of Streben or striving of the I is the necessary condition of finite or individual consciousness. The I posits itself absolutely, but in doing so it posits the not-I as well, therefore it posits itself absolutely as self-limiting I. If there was no limitation on the infinite striving of the I’s activity, then there would be no I, at least as we know it. Firstly, the paper emphasizes why this activity or striving needs to be infinite, and at the same time determined. Then, why is it necessary for theoretical self-consciousness, regarding the idea of Anstoss, divided self and absolute I. Finally, why is it also necessary for practical standpoint, considering the ideas of practical striving, tendency, longing, drive, and desire (both in individual striving towards self-coherence and social drive for intersubjectivity). It will be concluded that the I possesses a “dual nature” or divided character: it is finite, but it strives towards infinity. The tension arising from this contradiction should be the moving force of the I.

Designing and coding with BBC micro:bit to solve a real-world task – a challenging movement between contexts

Designing programmed technological solutions (PTS) with programming materials has become a way to contextualise educational content related to PTS and programming. However, studies show that pupils have difficulties conceptualising central phenomena involved in the process, which affects their ability to design PTS. In order to understand these difficulties, this study investigates pupils’ ways of experiencing the process of solving a real-world task with a programming material. The study takes its point of departure from a previous study that identified two central phenomena, the dual nature (structure and function) of PTS and the BBC micro:bit material, when pupils, aged 10 and 14, were designing a burglar alarm with the BBC micro:bit. The data was revisited with the aim of analysing pupils’ sequential discernment of critical aspects of the phenomena (i.e. aspects necessary to discern in order to understand phenomena), and how this affects how the design process unfolds. The results show that the movement from the real-world context toward the BBC micro:bit context is challenging. Pupils need to be able to connect conditions in the real-world context both to aspects of the dual nature of their PTS, and to aspects of the BBC micro:bit material that represent the dual nature. This suggests the importance of appreciating the BBC micro:bit context and the real-world context in relation to the dual nature of PTS, and of addressing the sequential stages of the process in which aspects of phenomena and their interrelations are emphasised, to help pupils see the PTS in the changing contexts.

INTERNET USER’S BEHAVIOR FROM THE STANDPOINT OF THE NEURAL NETWORK THEORY OF SOCIETY: PREREQUISITES FOR THE META-EDUCATION CONCEPT FORMATION

An analysis of the behavior of Internet users from the point of view of their preferences in the choice of information sources and the effectiveness of their impact is presented. It is shown that the modern infocommunication space has undergone qualitative changes in the most recent time, and these transformations are already having a pronounced impact on higher education, mainly through the factor of competition between information sources. It is shown that these transformations can be interpreted as the evolution of the noosphere, which is considered as a global infocommunication network, in which non-trivial transpersonal information objects are formed. Their existence leads to the fact that the human intellect has a dual nature - both individual and collective principles are present in it at the same time. The latter is responsible for such phenomena as the collective unconscious, understood in the sense of Jung. It is shown that the neural network model of the noosphere makes it possible to formulate a similar concept of "professional collective unconscious", which is responsible for professional intuition, acts of creativity, etc. In turn, the existence of the professional collective unconscious forces us to radically reconsider the content of what is called training and move to the concept of meta-learning, which, among other things, involves stimulating transitions from one level of interaction with transpersonal information structures that make up the professional collective unconscious to another.

Transcending the Border: The Encounter with the Other in Tinker Bell and the Secret of the Wings

This article explores the representation of borders and cosmopolitanism in the film Tinker Bell and the Secret of the Wings (2012), the fourth title in the Disney fairies franchise. The film tells the story of a world divided into two territories, the Winter Woods and Pixie Hollow. A ban on cross-border mobility prohibits any kind of interaction between the inhabitants of the two worlds. Tinker Bell, the main character in the film, feels the urge to break the law and cross to the other side, where she meets her twin sister and finds out the reason for the ban. Tinker Bell and the Secret of the Wings is a border film that deals with the processes of border construction and dissolution while also highlighting the potential, and some of the risks, of the dismantling of borders. This article analyses the film’s use of different spaces that, in line with the dual nature of borders theorised by, among others, Gloria Anzaldúa, work simultaneously as dividing lines and borderlands. Gerard Delanty’s concept of cosmopolitan moments is used to analyse the articulation of cross-border relationships in the film.
