Исследование качества высшего инженерного образования по данным анкетирования студентов с помощью метода нелинейных главных компонент (NLPCA)
The paper explores a suitability of higher education quality measurement from student's point of view, and analyses results of interviewing of students from engineering specialties in Perm universities. Nonlinear Principal Components Analysis (NLPCA) in interpretation of Gifi system was used as the tool for data processing. It takes into account a dissimilar statistical nature of questionnaire indicators. The method can be very promising for various socio-economic researches.

The paper is focused on changes in higher engineering education in Russia over the last decade. We assume that, as a result of technological and organizational changes in the markets young engineers are taught to work in, changes in education may be called for. The key change in the markets for engineers in Russia consists of the transition from planned to market economy, and thus the appearance of markets per se, and also in a shift away from a focus on the defense industry. To identify the possible changes and assess the current state of engineering education, we compare opinions of four target groups: university administrators, students, recent graduates, and employers.
An integral financial stability index is constructed using Israel macroeconomic data. Approaches relying on the use of dependent variable as well as principal component mathod and its modifications are examined. Obtained indexes are compared in terms of their forecast quality. In case of no dependent variable structural shift is analyzed.
We consider certain spaces of functions on the circle, which naturally appear in harmonic analysis, and superposition operators on these spaces. We study the following question: which functions have the property that each their superposition with a homeomorphism of the circle belongs to a given space? We also study the multidimensional case.
We consider the spaces of functions on the m-dimensional torus, whose Fourier transform is p -summable. We obtain estimates for the norms of the exponential functions deformed by a C1 -smooth phase. The results generalize to the multidimensional case the one-dimensional results obtained by the author earlier in “Quantitative estimates in the Beurling—Helson theorem”, Sbornik: Mathematics, 201:12 (2010), 1811 – 1836.
