ОСОБЕННОСТИ ВЕРБАЛЬНОГО ОФОРМЛЕНИЯ ОБРАЗА АВТОРА В РЕЧЕВОМ ЖАНРЕ «НИГЕРИЙСКОЕ ПИСЬМО»

This article is devoted to the results of the analysis of the speech genre ‘Nigerian letter’ based on the main criteria - the image of the author, that corresponds to one of the components of the model of a speech genre by T.V. Shmeleva. The analysis is based on the three groups of nigerian letters - messages aimed at getting money from fraudulent recipients - in English, Russian, French, Italian and Spanish. The classification’s criteria was the image of the author: heir in trouble, a businessman in need of a partner, a man dying from an incurable disease. The analysis of three types of epistolary texts revealed the characteristic verbal means of realization of com-munication strategy of manipulation on each of the three stages of the manipulative influence: preparatory, attractive and perlocutionary. The conclusions about the correlation of genre features of the text and manipulative character rendering text to the recipient were made.В данной статье представлены результаты анализа речевого жанра «нигерийское письмо» по основному критерию «образ автора», соответствующему одному из компонентов анкеты речевого жанра Т.В. Шмелёвой. Материалом для анализа послужили три группы «нигерийских писем» − сообщений, направленных на мошенническое получение денег от получателей писем - на английском, русском, французском, итальянском и испанском языках. Критерием для классификации писем послужил тип образа автора: наследник, попавший в беду; бизнесмен, нуждающийся в партнёрстве; умирающий от неизлечимой болезни. В ходе анализа в трёх типах эпистолярных текстов были выявлены характерные вербальные средства реализации коммуникативной стратегии манипуляции на каждом из трёх этапов манипулятивного воздействия: подготовительном, аттракционном и перлокутивном. Сделаны выводы о корреляции жанровых особенностей построения текста и характером оказания манипулятивного воздействия на реципиента текста

Activity-dependent spinal cord neuromodulation rapidly restores trunk and leg motor functions after complete paralysis

Epidural electrical stimulation (EES) targeting the dorsal roots of lumbosacral segments restores walking in people with spinal cord injury (SCI). However, EES is delivered with multielectrode paddle leads that were originally designed to target the dorsal column of the spinal cord. Here, we hypothesized that an arrangement of electrodes targeting the ensemble of dorsal roots involved in leg and trunk movements would result in superior efficacy, restoring more diverse motor activities after the most severe SCI. To test this hypothesis, we established a computational framework that informed the optimal arrangement of electrodes on a new paddle lead and guided its neurosurgical positioning. We also developed software supporting the rapid configuration of activity-specific stimulation programs that reproduced the natural activation of motor neurons underlying each activity. We tested these neurotechnologies in three individuals with complete sensorimotor paralysis as part of an ongoing clinical trial ( www.clinicaltrials.gov identifier NCT02936453). Within a single day, activity-specific stimulation programs enabled these three individuals to stand, walk, cycle, swim and control trunk movements. Neurorehabilitation mediated sufficient improvement to restore these activities in community settings, opening a realistic path to support everyday mobility with EES in people with SCI
