This study analyzes the interregional effects of innovation in Russia. The hypothesis of the presence of interregional effects is tested by combining the methods of spatial econometrics and Bayesian approach. Using panel data on Russian regions for the period from 2000 to 2021, the author calculates posterior probabilities for a set of spatial regression models ...

This article endeavors to construct a composite indicator designed to facilitate the comparative assessment of institutional capacities across diverse political systems. The focal point of analysis resides within the domain of state capacity, a pivotal determinant for a myriad of inquiries that seek to evaluate the efficacy of public policy implementation across varying spheres. The ...

The article presents a comparative analysis of the issues related to the development of human potential in two republics in Russia today — in the Republic of Kalmykia and the Republic of Tuva. The republics have relatively similar rankings in terms of human development index. The conclusions of the research are based on an analysis ...

Scholars often use language to proxy ethnic identity in studies of conflict and separatism. This conflation of language and ethnicity is misleading: language can cut across ethnic divides and itself has a strong link to identity and social mobility. Language can therefore influence political preferences independently of ethnicity. Results from an original survey of two ...

Models for converting expert-coded data to estimates of latent concepts assume different data-generating processes (DGPs). In this paper, we simulate ecologically valid data according to different assumptions, and examine the degree to which common methods for aggregating expert-coded data (1) recover true values and (2) construct appropriate coverage intervals. We find that the mean and ...

The Varieties of Democracy (V-Dem) project relies on country experts who code a host of ordinal variables, providing subjective ratings of latent|that is, not directly observable regime characteristics over time. Sets of around ve experts rate each case (country-year observation), and each of these raters works independently. Since raters may diverge in their coding because ...

This article deals with the issues of quality assurance in forensic examination and pre-requisites for confidence in expert findings. It describes the models of forensic examination in a number of developed common law (England) and civil law (Germany, France), jurisdictions, presents institutional and procedural specifics of the use of expert evidence in courts. The best ...

The study analyzed the typical patterns of children's answers to items in a computerized reading comprehension test and carried out a statistical verification of the expert-based rules for scoring. We demonstrate that the response patterns are not organized according to the Blooms taxonomy of cognitive processes, and that children exhibit a variety of response patterns. ...

The article proposes a methodology for using macro-level stress testing based on the results of business tendency surveys to study possible scenarios for the development of crisis dynamics triggered by external unforeseen supply and demand shocks, as in the case of the COVID-19 pandemic, as well as a review of existing approaches in the field ...

Experts code latent quantities for many influential political science datasets. Although scholars are aware of the importance of accounting for variation in expert reliability when aggregating such data, they have not systematically explored either the factors affecting expert reliability or the degree to which these factors influence estimates of latent concepts. Here we provide a ...

Bayesian inference is known to provide a general framework for incorporating prior knowledge or specific properties into machine learning models via carefully choosing a prior distribution. In this work, we propose a new type of prior distributions for convolutional neural networks, deep weight prior (DWP), that exploit generative models to encourage a specific structure of ...

In this article we consider the trajectory of xenophobia in Russia since the disintegration of the Soviet Union. Using survey data from 1996, 2004, and 2012, we examine Russians' negative attitudes toward seven outgroups over time. We also statistically analyze the degree to which correlates of xenophobia have changed between 1996 and 2012. We find ...

The disintegration of the Soviet Union is an essential case for the study of ethnic politics and identity-based mobilization. However, analyses in this article demonstrate that commonly used measures of ethnic diversity and politically relevant group concentration show little consistent relationship with events of ethnic mobilization in Soviet regions during the period 1987-1992. In contrast, ...

Data sets quantifying phenomena of social-scientific interest often use multiple experts to code latent concepts. While it remains standard practice to report the average score across experts, experts likely vary in both their expertise and their interpretation of question scales. As a result, the mean may be an inaccurate statistic. Item-response theory (IRT) models provide ...
