Independent Evaluation

The problem of external independent evaluation in English for admission Master`s degree programs in Ukraine is considered in the article. The perspective for further improvement of English teaching and learning standards at Ukrainian universities has been found. The correspondence to the CEFR basic levels and English proficiency has been identified. Conceptual Principles of State Policy on the Development of English in the Field of Higher Education are considered. The study included 1546 participants. The age of students, who studied to gain the first higher education, was between 17 and 20. The students were not familiar with the structure of External Independent Evaluation and they have never passed it. The research was carried out during the period 2018–2019. The relevance of English language competence in the professional context is noted emphasized as a key point of the presented research. The necessity to provide a sufficient competitive level for Ukrainian graduates through improving correspondent English language training has been considered. The study is based on a study of reports by British experts and contemporary scientific publications presented international researchers have focused on the problems of internationalization and perspectives for Ukrainian universities in the English language dimension. The relevance of studying and adaptation of the UK higher education successful practice has been highlighted. The problems and potential ways of improving students` English language proficiency in the given context are identified. In particular, the study contains important recommendations regarding the number of contact hours and the required levels of English proficiency for the main groups of participants in the educational process in higher education according to international standards.

Central Chernozem

The article describes the main morphological and biological features of alfalfa varieties included in the State register of breeding achievements approved for use in the Central Chernozem zone of Russia. A total of 32 alfalfa varieties are included in the State register. This is 9 varieties of blue alfalfa (Medicago sativa L. subsp. Sativa) of domestic selection and 8 foreign, 11 varieties of variable alfalfa (Medicago sativa L. nothosubsp. varia (Martyn) Arcang.) domestic selection and 1 variety of foreign and 3 varieties of yellow alfalfa (Medicago sativa L. subsp. falcata (L.) Arcang.). It shows the average and maximum yield of varieties determined in the process of state variety testing, as well as independent evaluation in research institutions in the region. Varieties of blue alfalfa of domestic selection Kevsala, Elena, Satellite, Vavilovskaya Yubileynaya were the most productive. The average yield of dry matter of these varieties reaches 8.4–9.2 t/ha, the maximum — 15.3–17.7 t/ha. Alfalfa varieties Timbale and Galaxy were the most productive among foreign varieties: the average yield of dry matter was 8.1 and 8.3 t/ha, the maximum – 15.5 and 17.2 t/ha. Varieties of alfalfa variable Vitalina and Vela provided an average yield of dry matter of 7.6 and 9.0 t/ha, the maximum yield reached 15.4 and 18.1 t/ha.

Lateral Flow Tests

New lateral flow tests for the diagnosis of Neisseria meningitidis (Nm) (serogroups A, C, W, X, and Y), MeningoSpeed, and Streptococcus pneumoniae (Sp), PneumoSpeed, developed to support rapid outbreak detection in Africa, have shown good performance under laboratory conditions. We conducted an independent evaluation of both tests under field conditions in Burkina Faso and Niger, in 2018–2019. The tests were performed in the cerebrospinal fluid of suspected meningitis cases from health centers in alert districts and compared to reverse transcription polymerase chain reaction tests performed at national reference laboratories (NRLs). Health staff were interviewed about feasibility. A total of 327 cases were tested at the NRLs, with 26% confirmed Nm (NmC 63% and NmX 37%) and 8% Sp. Sensitivity and specificity were, respectively, 95% (95% CI: 89–99) and 90% (95% CI: 86–94) for Nm and 92% (95% CI: 75–99) and 99% (95% CI: 97–100) for Sp. Positive and negative predictive values were, respectively, 77% (95% CI: 68–85) and 98% (95% CI: 95–100) for Nm and 86% (95% CI: 67–96) and 99% (95% CI: 98–100) for Sp. Concordance showed 82% agreement for Nm and 97% for Sp. Interviewed staff evaluated the tests as easy to use and to interpret and were confident in their readings. Results suggest overall good performance of both tests and potential usefulness in meningitis outbreak detection.
