NMR spectroscopy has become an indispensable tool for the metabolic profiling of foods and food products. In the present protocol, we report an analytical approach based on liquid-state NMR for the determination of polar and nonpolar metabolites in some common liquid (wine, spirits, juice) and solid (cheese, coffee, honey) foods. Although the diversity of foods precludes the use of a single protocol, with small modifications, the proposed methodologies can be adapted to a broader range of foodstuffs.

The literature review shows that the current educational paradigm with the shift to a studentoriented model has transformed the roles of both the teacher and the student, where the latter takes a more active and conscious part in educational processes. Peer assessment has proven to have a positive impact on L2 learning and teaching, having various benefits for both the teacher and the student, and its usefulness and efficiency has been supported by various research. While educators are aware of such positive impact, students' attitudes towards peer assessment may vary. This study aims to examine the attitudes towards peer assessment in an L2 phonetics class of first year undergraduate students of the Faculty of Foreign Languages and Area Studies at Lomonosov Moscow State University. Thirty-four participants responded to a questionnaire, the main aim of which was to explore their attitudes towards peer assessment and its effectiveness in terms of developing their phonological competence and also their preferences regarding oral and written peer assessment in class. Responses were analysed through JASP software. The results of the study prove students' awareness of the significance of peer assessment and their positive attitudes towards it with approximately 85% of the participants regarding it as a useful component of constructive feedback and approximately 91% of the participants acknowledging the usefulness of peer assessment for the development of their own phonological skills. The study also offers a pronunciation peer assessment scale to contribute to teaching and learning L2 phonetics.

This study examined the attitudes of postgraduate biology students of three top-ranked Russian universities towards the foreign accents of non-native English-speaking lecturers. Fifty participants responded to a questionnaire, the main purpose of which was to explore the listeners’ perceptions of professors’ accents and their influence on students’ ability to concentrate on and comprehend the lecture material. The research included a quantitative analysis of gathered descriptive data. The results of the study show Russian students’ tolerant attitudes to foreign accents of non-native lecturers and demonstrate their readiness to comprehend non-standard English-medium speech of non-native representatives of the international natural sciences academic community.

Аннотация. Настоящая статья содержит результаты анализа требований основных образовательных стандартов высшего образования РФ (Федеральный государственный стандарт высшего образования, 2014 г. и Образовательный стандарт МГУ имени М.В. Ломоносова, 2015 г.) по направлению подготовки «Лингвистика» (бакалавр) к владению фонетическими навыками в устной речевой деятельности. Выявленная в образовательных стандартах необходимость вести «эффективное устное общение» указывает на возросшую значимость обучения фонетике иностранного языка как основного условия качественного оформления устной речи в языковом вузе сегодня. Ключевые слова: образовательный стандарт, фонетика, обучение фонетике, устная речевая деятельность, фонетические навыки.
