Microstructural anatomical differences between bilinguals and monolinguals
DTI is an established method to study cerebral white-matter microstructure. Two established measures of DTI are fractional anisotropy (FA) and mean diffusivity (MD) and both differ for bilingual and monolingual speakers. Less is known about differences in two other measures called radial (RD) and axial diffusivity (AD). We report differences in mean RD and AD-values in the right superior longitudinal fasciculus (SLF) and forceps minor between bilingual (Hindi–English) and monolingual (English) speakers as well as differences in mean FA-values in the anterior thalamic radiation, right inferior fronto-occipital and inferior longitudinal fasciculus (ILF) and mean MD-values in forceps minor and bilateral SLF. Noteworthy, a positive correlation between L2 proficiency and mean RD-values in the right SLF was observed. We suggest that changes in the geometry of white matter tracts reflect regular bilingual language experience and contend that neuroplasticity in right SLF results from demands on cognitive control for bilingual speakers.
This paper investigates the language situation in Moscow schools with an ethnocultural component – a new form of national schools. The analysis is based on interviews which were recorded in 2007, in two Moscow schools, one of them with Armenian ethno-cultural component, and the other, with Azeri. The sample included ten students from each school (five boys and five girls).
In the paper the process of linguistic integration of Azeri and Armenian children into modern Russian society is analyzed. The comparison between these two groups is particularly appealing, because the effects of Soviet Russification, and the language situations in general, were different in Armenia and in Azerbaijan. I show that this difference influences the use of language by Azeri and Armenian children.
This study examines knowledge of Russian non-compositional expressions (idioms) of Heritage Russian speakers. In this paper we present the results of interviews and experiments conducted in immigrant families and targeting both parents (first-generation immigrants) and their children (heritage speakers). In the current study Heritage Russian speakers are children who were born in the USA and use Russian language only with their family. Their parents who left Russia around 1980- 1990 are baseline speakers. The study has two parts: the first one is dedicated to the general description of their speech while the second section is devoted to the cultural side of their language. In this respect, the recognition and knowledge of Russian non-compositional expressions were tested. As Heritage Russian speakers are bilinguals, their cultural background is rather ambiguous. The current research proves the idea that Heritage Russian speakers do not share the same cultural background as their parents.
Adequate assessment of individual functional motor potentials is important for developing appropriate rehabilitation strategies in ischemic stroke . Microstructural changes in corticospinal tract (CST) and corpus callosum (CC) were repeatedly correlated to post-stroke outcome [2, 3]. However, relationship between them and functional recovery remains unclear. Here we investigated relationship between integrity of CST and CC assessed with diffusion tensor imaging (DTI) and brain functional state assessed with navigated transcranial magnetic stimulation (nTMS) in chronic ischemic supratentorial stroke.
This book includes proceedings of the conference, that took place in the National Academy of Sciences of Belarus in October 2015. The articles are dedicated to phonetics, grammar, lexicology, lexicography and language functioning in modern global world.
The volume includes proceedings of the 23th Scandianvian Conference of Linguistics (SCL 23) that was held at Uppsala University 1–3 October 2008. It includes studies covering a wide spectrum of approaches to linguistics, for example, cross-linguistic typological studies, linguistic variation and language change in contact situations as well as studies relating to bilingualism and to second and foreign language learning.
Variation and variety, basic linguistic notions elaborated, among many others, in Prof. Schweitzer’s works, are addressed in the article in the context of an increase in variation in modern Russian under the influence of global English. The increase in contact-induced variation is investigated in connection with the following: 1) an increase in borrowings and semantic calques from English into Russian, 2) an increase in Russian-English code-switching and code-mixing, and 3) major changes in Russian-English interaction contributing to the change of status of English in Russia and the initiation of a specific regional variety of English, Russia(n) English.
The article presents the review of the manual titled The handbook of bilingualism and multilingualism, published in 2013 by Wiley-Blackwell Publishing and edited by Tej K. Bhatia and William C. Ritchie.
The article presents a review of foreign research studies of the possible effects of bilingualism on different aspects of cognitive development of an individual and on the process of the third language acquisition. Such effects are viewed as positive ones by most authors.
The distractive effects on attentional task performance in different paradigms are analyzed in this paper. I demonstrate how distractors may negatively affect (interference effect), positively (redundancy effect) or neutrally (null effect). Distractor effects described in literature are classified in accordance with their hypothetical source. The general rule of the theory is also introduced. It contains the formal prediction of the particular distractor effect, based on entropy and redundancy measures from the mathematical theory of communication (Shannon, 1948). Single- vs dual-process frameworks are considered for hypothetical mechanisms which underpin the distractor effects. Distractor profiles (DPs) are also introduced for the formalization and simple visualization of experimental data concerning the distractor effects. Typical shapes of DPs and their interpretations are discussed with examples from three frequently cited experiments. Finally, the paper introduces hierarchical hypothesis that states the level-fashion modulating interrelations between distractor effects of different classes.
This article describes the expierence of studying factors influencing the social well-being of educational migrants as mesured by means of a psychological well-being scale (A. Perrudet-Badoux, G.A. Mendelsohn, J.Chiche, 1988) previously adapted for Russian by M.V. Sokolova. A statistical analysis of the scale's reliability is performed. Trends in dynamics of subjective well-being are indentified on the basis the correlations analysis between the condbtbions of adaptation and its success rate, and potential mechanisms for developing subjective well-being among student migrants living in student hostels are described. Particular attention is paid to commuting as a factor of adaptation.
This book contains the proceedings of the 4th International Conference on Computer Supported Education (CSEDU 2012) which was organized and sponsored by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) and technically co-sponsored by SPEE (Portuguese Society for Engineering Education), IGIP (International Society for Engineering Education), ROLE (Responsive Open Learning Environments) and IFIP TC3 (International Federation for Information Processing - Technical Committee 3 - ICT and Education).
CSEDU has become an annual meeting place for presenting and discussing learning paradigms, best practices and case studies that concern innovative computer-supported learning strategies, institutional policies on technology-enhanced learning including learning from distance, supported by technology. The Web is currently a preferred medium for distance learning and the learning practice in this context is usually referred to as e-learning or technology-enhanced learning. CSEDU 2012 is expected to give an overview of the state of the art in technology-enhanced learning and to also outline upcoming trends and promote discussions about the education potential of new learning technologies in the academic and corporate world.
This conference brings together researchers and practitioners interested in methodologies and applications related to the education field. It has five main topic areas, covering different aspects of Computer Supported Education, including "Information Technologies Supporting Learning", "Learning/Teaching Methodologies and Assessment", "Social Context and Learning Environments", "Domain Applications and Case Studies" and "Ubiquitous Learning". We believe the proceedings, demonstrate new and innovative solutions, and highlight technical problems in each field that are challenging and worthwhile.
CSEDU 2012 received 243 paper submissions from 58 countries in all continents. A double-blind review process was enforced, with the help of the 297 experts who are members of the conference program committee, all of them internationally recognized in one of the main conference topic areas. Only 29 papers were selected to be published and presented as full papers, i.e. completed work (10 pages in proceedings / 30' oral presentations). 73 papers, describing work-in-progress, were selected as short papers for 20' oral presentation. Furthermore 37 papers were presented as posters. The full-paper acceptance ratio was thus 12%, and the total oral paper acceptance ratio was less than 42%. These ratios denote a high level of quality, which we intend to maintain and reinforce in the next edition of this conference.
The high quality of the CSEDU 2012 programme is enhanced by three keynote lectures, delivered by distinguished guests who are renowned experts in their fields, including (alphabetically): Joseph Trimmer (Ball State University, United States), David Kaufman (Simon Fraser University, Canada) and Hugh Davis (University of Southampton, United Kingdom).
For the fourth edition of the conference we extended and ensured appropriate indexing of the proceedings of CSEDU including DBLP, INSPEC, EI and Thomson Reuters Conference Proceedings Citation Index. Besides the proceedings edited by SciTePress, a short list of papers presented at the conference will be selected for publication of extended and revised versions in the Journal of Education and Information Technologies. Furthermore, all presented papers will soon be available at the SciTePress digital library.
The conference is complemented with two special sessions, focusing on specialized aspects of computer supported education; namely, a Special Session on Enhancing Student Engagement in e-Learning (ESEeL 2012) and a Special Session on Serious Games on Computer Science Learning (SGoCSL 2012).
Building an interesting and successful program for the conference required the dedicated effort of many people. Firstly, we must thank the authors, whose research and development efforts are recorded here. Secondly, we thank the members of the program committee and additional reviewers for their diligence and expert reviewing. We also wish to include here a word of appreciation for the excellent organization provided by the conference secretariat, from INSTICC, who have smoothly and efficiently prepared the most appropriate environment for a productive meeting and scientific networking. Last but not least, we thank the invited speakers for their invaluable contribution and for taking the time to synthesize and deliver their talks.
