THEORIES OF ETHNICITY, NATIONALITY, AND ETHNIC IDENTITY

Ethnicity, nationality, and ethnic identity remain to be unresolved issues that need to be addressed. It is thus important to compare different approaches to understand the nature of ethnic phenomena and to identify appropriate techniques to understand the essence of «nation-building» concept. First, the article discusses the concepts of nation, ethnicity, changes in ethnic identity where the concepts of ethnos and nation are further explained. Second, the nature, dynamics and factors of the processes of ethnic identity are analyzed. Third, the author seeks answers to questions of why some ethnic identities change, while others remain unchanged. Fourth, ethnicity in conflict, the role of «belonging to a certain ethnic group» is considered. Finally, past and present debates of the primordialist and constructivist approaches to nation-building are described. The main methodology of the article is a comparative analysis of the theoretical literature of foreign and domestic research through the lenses of primordialism and constructivism. The paper argues that there is no reason for all ethnic groups to reach the level of a nation, that constructive theory has advantages at the highest level of integration between nations and ethnic groups in the 21st century, and that ethnic identity is adaptable and changeable over time. The results of this work contribute to further studies and scientific works related to the nation-building in Kazakhstan.

Power Generation Prediction Model Based on Improved PSO-BPNN

Electricity generation greatly impacts economic development, and electricity is indispensable for production, transportation, and living. Therefore, forecasting electricity generation accurately is of great research significance for the development of the country and the livelihood of the people. Because of the nonlinear relationship between electricity generation and the influencing factors, this paper, supported by the above data in China over the past 20 years, describes a prediction model based on Improved Particle Swarm Optimization (PSO) -- Back Propagation Neural Network (BPNN) to optimize the algorithm about forecasting electricity generation. The experimental results have shown that the accuracy and stability of the prediction model were constructed in this paper, which was improved by about 2%-6% compared with the traditional ones. In addition, the application of this model could provide a constructive theory for some relevant works in the electric-power industry.

Existence Theorem for Noninstantaneous Impulsive Evolution Equations

In this note, the variational form of the classical Lax–Milgram theorem is used for the divulgence of variational structure of the first-order noninstantaneous impulsive linear evolution equation. The existence and uniqueness of the weak solution of the problem is obtained. In future, this constructive theory can be used for the corresponding semilinear problems.

Embeddings of Bishop spaces

We develop the basic constructive theory of embeddings of Bishop spaces in parallel to the basic classical theory of embeddings of topological spaces. The theory of Bishop spaces is a constructive approach to point-function topology and a natural constructive alternative to the classical theory of the rings of continuous functions. Our most significant result is the translation of the classical Urysohn extension theorem within the theory of Bishop spaces. The related theory of the zero sets of a Bishop topology is also included. We work within $\textrm{BISH}^{\ast }$, Bishop’s informal system of constructive mathematics $\textrm{BISH}$ equipped with inductive definitions with rules of countably many premises.
