National and cultural trend in a research of the Russian political and legal space of the beginning of the 21st century: mental measurement of modernization strategy

Authors of the article allocate and in details consider the so-called “not positive” components of national legal reality reflecting difficult morphology of public and individual legal consciousness and included in structure of legal mentality. Such approach allows to allocate various approaches to identification and typification of such significant element of national legal and political space as legal mentality, which accounting, undoubtedly, has huge informative value within national and cultural and even intellectual and technological trend of evolution of domestic and social and legal, and political and institutional space.

The Ability of Different Imputation Methods for Missing Values in Mental Measurement Questionnaires

Background Incomplete data are of particular important influence in mental measurement questionnaires. Most experts, however, mostly focus on clinical trials and cohort studies and generally pay less attention to this deficiency. We aim is to compare the accuracy of four common methods for handling items missing from different psychology questionnaires according to the items non-response rates. Method All data were drawn from the previous studies including the self-acceptance scale (SAQ), the activities of daily living scale (ADL) and self-esteem scale (RSES). SAQ and ADL dataset, simulation group, were used to compare and assess the ability of four imputation methods which are direct deletion, mode imputation, Hot-deck (HD) imputation and multiple imputation (MI) by absolute deviation, the root mean square error and average relative error in missing proportions of 5%, 10%, 15% and 20%. RSES dataset, validation group, was used to test the application of imputation methods. All analyses were finished by SAS 9.4. Results The biases obtained by MI are the smallest under various missing proportions. HD imputation approach performed the lowest absolute deviation of standard deviation values. But they got the similar results and the performances of them are obviously better than direct deletion and mode imputation. In a real world situation, the respondents' average score in complete data set was 28.22 ± 4.63, which are not much different from imputed datasets. The direction of the influence of the five factors on self-esteem was consistent, although there were some differences in the size and range of OR values in logistic regression model. Conclusion MI shows the best performance while it demands slightly more data analytic capacity and skills of programming. And HD could be considered to impute missing values in psychological investigation when MI cannot be performed due to limited circumstances.

Research Methodology in Deaf Education

The purpose of this chapter is to provide historical context for research in deaf education. Educators began conducting research from the time of the establishment of the first school for the deaf in the United States in 1816, long before the development of sophisticated research methodology. Investigators used the resources at hand and addressed issues of importance in their time. First reports tended to be anecdotal and self-report, followed by demographic studies. Research in the first half of the twentieth century concentrated on mental measurement and standardized tests of academic achievement. From this developed a core of professionals with skills to conduct studies in a wide range of areas and consumers with the interest to profit from them. Since that time, advances have been made in the study of sign languages, language acquisition, intellectual and cognitive assessment, and measurement of academic achievement, resulting in a broad array of research approaches.

THE LEGITIMIZATION OF INSTITUTIONS OF PUBLIC AUTHORITY IN THE POLITICO-LEGAL SPACE OF RUSSIA: PECULIARITIES OF MENTAL MEASUREMENTS

The article highlighted the structural elements of mental measurement processes and factors of legitimation of State authority in the domestic political and legal space. The focus is on the two alternative models of post-Soviet State-legal construction, both conservative and Liberal, which largely determines the logic of national statehood at the turn of the 20th-21st centuries. In this context, the author highlights the specificity of the legitimation of power institutions, identifies the basic parameters of its study, raises questions about the possible prospects for the modernization of the power relations in the context of Russian culture-civilizational identity.
