The Impact

The rise in the intelligence tests scores across the generations, known as the Flynn effect, is widely studied in various countries due to critical role of intelligence as the most important component of human capital. Several explanations for the Flynn effect have been proposed, none of which have a predominant status. At least partly it can be explained by deficiency of studies devoted to the influence of various moderators on the speed and trajectory of the intelligence scores gain. This study presents the results of an analysis of the impact on the Flynn effect of such a poorly studied factor as the settlements’ size of a populated point. Intelligence scores (n = 267116) obtained during large-scale online testing of men aged 18—40 years between 2012 and 2019 were distributed among seven categories of populated points determined by their population size. Significant differences were revealed both in the level of IQ scores and in the rate of its growth, depend- ing on the respondents belonging to these categories. Differences in the level of intelligence of residents of megalopolises and small towns are 7 IQ-points on average, and the dynamics of growth in intelligence scores in the period 1983—2000 differs in some of the categories by more than 2 times. The smallest trend for this period was in cities with a population of 100 to 249.9 thousand people. Possible explanations for the differences are suggested. In particular, the selective migration of the most educated and intellectual part of their population to large cities and capitals may be a possible mechanism for inhibiting the Flynn effect in settlements with a smaller population.

The Impact

The formation of large urban agglomerations makes possible to ensure more rational use of productive resources and increase labor productivity. Large cities, as a rule, have developed infrastructure and educational sector. However, there is a difficult ecological situation in many large cities. With a large scale of the city, transport accessibility is seriously complicated. From the viewpoint of favorable habitat, good ecological conditions, small and medium-sized cities often benefit from urban agglomerations. In the Russian Federation, due to the dominance of raw materials industries and the underdevelopment of local industry, small and medium-sized cities are in decline. This predetermines the need to develop special measures to support such territorial entities. The study is based on the generalization of data on the change in the ecological situation in large cities and the impact of atmospheric air pollution on the quality of life of the population. In the framework of the study, the conclusion was substantiated about the expediency of carrying out special measures aimed at improving the ecological situation in large cities and developing measures to support small and medium-sized cities. The recommendations for stimulating the development of production in small and medium-sized cities are grounded. The results of the study can find applications in the practice of regional management.

Iq Scores

The term «the Flynn Effect» is accepted to designate a phenomenon of the observed rising in IQ test performance over time. This phenomenon causes considerable interest around the world, not only among psychologists. It is studied to some extent in several tens of countries; however Russia was not included into their number until recently. In order to bridge this gap we take advantage of analyzing results of large-scale voluntary online testing on the site http://www.mil.ru by means of psychometrically reliable cognitive test in 2012—18. Its items are addressed to verbal, numerical, spatial and perceptual speed factors of intelligence (with prevalence of the two first); it is possible to refer not less than ¾ of them to the sphere of crystallized intelligence. After performance of all cleaning procedures there were 238363 protocols suitable for the analysis. All participants are presumably men at the age of 18—40 years (M = 26.4±5.1). The analysis of IQ scores among the persons who were born in 1974—1999 revealed that up to the middle of the 80th the decline of the test scores took place which then replaced by linear growth which rate was estimated about 0.19 IQ points per year. However if the correction for probable lowering influence of increase in age is made, growth rate of IQ scores can become closer to 0.3 points. It is shown that these results as a whole are consistent with earlier registered growth of estimates of fluid intelligence in cohorts of law force university entrants. Hypotheses concerning relations of this phenomenon with features of a social and economic situation in Russia in the 80—90th of the last century are offered.

AbstractThe article presents the results of the review of the empirical literature regarding the impact of quantitative easing (QE) on emerging markets (EMs). The subject is of interest to policymakers and researchers due to the increasingly larger role of EMs in the world economy and the large-scale capital flows occurring after 2009. The review is conducted in a systematic manner and takes into consideration different methodological choices, samples and measurement issues. The paper puts the summarized results in the context of transmission channels identified in the literature. There are few distinct methodological approaches present in the literature. While there is a consensus regarding the direction of the impact of QE on EMs, its size and durability have not yet been assessed with sufficient precision. In addition, there are clear gaps in the empirical findings, not least related to relative underrepresentation of the CEE region (in particular, Poland).

The Impact

This book provides an account of how and why routine interactions break down and how such situational breakdowns lead to protest violence and other types of surprising social outcomes. It takes a close-up look at the dynamic processes of how situations unfold and compares their role to that of motivations, strategies, and other contextual factors. The book discusses factors that can draw us into violent situations and describes how and why we make uncommon individual and collective decisions. Covering different types of surprise outcomes from protest marches and uprisings turning violent to robbers failing to rob a store at gunpoint, it shows how unfolding situations can override our motivations and strategies and how emotions and culture, as well as rational thinking, still play a part in these events. The first chapters study protest violence in Germany and the United States from 1960 until 2010, taking a detailed look at what happens between the start of a protest and the eruption of violence or its peaceful conclusion. They compare the impact of such dynamics to the role of police strategies and culture, protesters’ claims and violent motivations, the black bloc and agents provocateurs. The analysis shows how violence is triggered, what determines its intensity, and which measures can avoid its outbreak. The book explores whether we find similar situational patterns leading to surprising outcomes in other types of small- and large-scale events: uprisings turning violent, such as Ferguson in 2014 and Baltimore in 2015, and failed armed store robberies.

The Impact

The inflammatory gene NLRP7 is the major gene responsible for recurrent complete hydatidiform moles (CHM), an abnormal pregnancy that can develop into gestational choriocarcinoma (CC). However, the role of NLRP7 in the development and immune tolerance of CC has not been investigated. Three approaches were employed to define the role of NLRP7 in CC development: (i) a clinical study that analyzed human placenta and sera collected from women with normal pregnancies, CHM or CC; (ii) an in vitro study that investigated the impact of NLRP7 knockdown on tumor growth and organization; and (iii) an in vivo study that used two CC mouse models, including an orthotopic model. NLRP7 and circulating inflammatory cytokines were upregulated in tumor cells and in CHM and CC. In tumor cells, NLRP7 functions in an inflammasome-independent manner and promoted their proliferation and 3D organization. Gravid mice placentas injected with CC cells invalidated for NLRP7, exhibited higher maternal immune response, developed smaller tumors, and displayed less metastases. Our data characterized the critical role of NLRP7 in CC and provided evidence of its contribution to the development of an immunosuppressive maternal microenvironment that not only downregulates the maternal immune response but also fosters the growth and progression of CC.

Cardiovascular disease remains a leading cause of mortality worldwide. Unresolved inflammation plays a critical role in cardiovascular diseases development. Specialized Pro-Resolving Mediators (SPMs), derived from long chain polyunsaturated fatty acids (LCPUFAs), enhances the host defense, by resolving the inflammation and tissue repair. In addition, SPMs also have anti-inflammatory properties. These physiological effects depend on the availability of LCPUFAs precursors and cellular metabolic balance. Most of the studies have focused on the impact of SPMs in adult cardiovascular health and diseases. In this review, we discuss LCPUFAs metabolism, SPMs, and their potential effect on cardiovascular health and diseases primarily focusing in neonates. A better understanding of the role of these SPMs in cardiovascular health and diseases in neonates could lead to the development of novel therapeutic approaches in cardiovascular dysfunction.

This paper studies the dynamics of key characteristics of the academic profession in Russia based on the analysis of university faculty in the two largest cities in Russia – Moscow and St Petersburg. We use data on Russian university faculty from two large-scale comparative studies of the academic profession (‘The Carnegie Study’ carried out in 1992 in 14 countries, including Russia, and ‘The Changing Academic Profession Study’, 2007–2012, with 19 participating countries and which Russia joined in 2012) to look at how faculty’s characteristics and attitudes toward different aspects of their academic life changed over 20 years (1992–2011) such as faculty’s views on reasons to leave or to stay at a university, on university’s management and the role of faculty in decision making. Using the example of universities in the two largest Russian cities, we demonstrate that the high degree of overall centralization of governance in Russian universities barely changed in 20 years. Our paper provides comparisons of teaching/research preferences and views on statements concerning personal strain associated with work, academic career perspectives, etc., not only in Russian universities between the years 1992 and 2012, but also in Russia and other ‘Changing Academic Profession’ countries.

The Impact

Photovoltaic devices based on amorphous silicon/crystalline silicon (a-Si:H/c-Si) heterojunction interfaces hold the highest efficiency as of date in the class of silicon-based devices with efficiencies exceeding 26% and are regarded as a promising technology for large-scale terrestrial PV applications. The detailed understanding behind the operation of this type of device is crucial to improving and optimizing its performance. SHJ solar cells have primarily two main interfaces that play a major role in their operation: the transparent conductive oxide (TCO)/a-Si:H interface and the a-Si:H/c-Si heterojunction interface. In the work presented here, a detailed analytical description is provided for the impact of both interfaces on the performance of such devices and especially on the device fill factor ( FF ). It has been found that the TCO work function can dramatically impact the FF by introducing a series resistance element in addition to limiting the forward biased current under illumination causing the well-known S-shape characteristic in the I-V curve of such devices. On the other hand, it is shown that the thermionic emission barrier at the heterojunction interface can play a major role in introducing an added series resistance factor due to the intrinsic a-Si:H buffer layer that is usually introduced to improve surface passivation. Theoretical explanation on the role of both interfaces on device operation based on 1D device simulation is experimentally verified. The I-V characteristics of fabricated devices were compared to the curves produced by simulation, and the observed degradation in the FF of fabricated devices was explained in light of analytical findings from simulation.

The Impact

The Coronavirus disease 2019 (COVID-19) pandemic has emerged as a significant and global public health crisis. Besides the rising number of cases and fatalities, the outbreak has also affected economies, employment and policies alike. As billions are being isolated at their homes to contain the infection, the uncertainty gives rise to mass hysteria and panic. Amidst this, there has been a hidden epidemic of “information” that makes COVID-19 stand out as a “digital infodemic” from the earlier outbreaks. Repeated and detailed content about the virus, geographical statistics, and multiple sources of information can all lead to chronic stress and confusion at times of crisis. Added to this is the plethora of misinformation, rumor and conspiracy theories circulating every day. With increased digitalization, media penetration has increased with a more significant number of people aiding in the “information pollution.” In this article, we glance at the unique evolution of COVID-19 as an “infodemic” in the hands of social media and the impact it had on its spread and public reaction. We then look at the ways forward in which the role of social media (as well as other digital platforms) can be integrated into social and public health, for a better symbiosis, “digital balance” and pandemic preparedness for the ongoing crisis and the future.

Abstract Persuasion success is often related to hard-to-measure characteristics, such as the way the persuader speaks. To examine how vocal tones impact persuasion in an online appeal, this research measures persuaders’ vocal tones in Kickstarter video pitches using novel audio mining technology. Connecting vocal tone dimensions with real-world funding outcomes offers insight into the impact of vocal tones on receivers’ actions. The core hypothesis of this paper is that a successful persuasion attempt is associated with vocal tones denoting (1) focus, (2) low stress, and (3) stable emotions. These three vocal tone dimensions—which are in line with the stereotype content model—matter because they allow receivers to make inferences about a persuader’s competence. The hypotheses are tested with a large-scale empirical study using Kickstarter data, which is then replicated in a different category. In addition, two controlled experiments provide evidence that perceptions of competence mediate the impact of the three vocal tones on persuasion attempt success. The results identify key indicators of persuasion attempt success and suggest a greater role for audio mining in academic consumer research.
