The Military

The task of choosing the rational number of power structures is always one of the main priorities of any political leadership of the state. An insufficient number of armed forces is a threat to the national security of the state; an excess number creates pressures on the development of the country's national economy. Today, when the development programs of the Armed Forces of Ukraine are being formed in the context of the practical application of their units and subunits to carry out combat missions, questions of choosing a priority approach to the formation (justification) of the rational size of the Armed Forces of Ukraine is an urgent issue. The article proposes a structure for conducting research on the development and implementation of the methodology of military-economic substantiation of the rational strength of the Armed Forces of Ukraine in the system of defense planning of Ukraine in the formation of programs for their development for the medium and long term. The main objectives of this methodology are: scientific substantiation of the range of the necessary strength of the Armed Forces of Ukraine for the period of the program of their development; the choice of the indicator of the rational size of the Armed Forces of Ukraine according to the years of the program from a certain range of its changes; military-economic substantiation of this number under the influence of various limiting factors. The development and implementation of such a methodology will increase the efficiency of the formation and implementation of development programs of the Armed Forces of Ukraine, as well as the efficiency of using public funds for the development of power structures.

This chapter situates the study of music teacher education within the larger body of music education and teacher education research. It problematizes the terms teacher training, teacher education, and best practice and introduces the concept of teaching as an “impossible profession.” Goals of teacher education, including reflective practice and adaptive expertise, are discussed. The chapter outlines the challenges that music teacher educators face as they try to prepare preservice teachers for the realities of P-12 school-based music education while instilling in these new colleagues a disposition toward change. It concludes with narratives that examine teachers’ descriptions of classroom relationships throughout the lens of presence in teaching as a way to remind teacher educators of the importance of their work to push the boundaries of music teacher education in order to serve the profession at large.

Abstract We prove that the integer part of the reciprocal of the tail of $\zeta (s)$ ζ ( s ) at a rational number $s=\frac{1}{p}$ s = 1 p for any integer with $p \geq 5$ p ≥ 5 or $s=\frac{2}{p}$ s = 2 p for any odd integer with $p \geq 5$ p ≥ 5 can be described essentially as the integer part of an explicit quantity corresponding to it. To deal with the case when $s=\frac{2}{p}$ s = 2 p , we use a result on the finiteness of integral points of certain curves over $\mathbb{Q}$ Q .

In this paper we show the lower bound of the set of non-zero -K2 for normal surface singularities establishing that this set has no accumulation points from above. We also prove that every accumulation point from below is a rational number and every positive integer is an accumulation point. Every rational number can be an accumulation point modulo ℤ. We determine all accumulation points in [0, 1]. If we fix the value -K2, then the values of pg, pa, mult, embdim and the numerical indices are bounded, while the numbers of the exceptional curves are not bounded.
