This paper contributes to the conceptualisation and operationalisation of the “technology trend” discussion in the scope of the Technology Foresight paradigm. It proposes a consistent logical approach to analysing technology trends and increase predictive potential of futures studies. The approach integrates Big Data analysis into the Foresight studies’ toolset by means of applying text mining, namely computerised analysis of large volumes of unstructured text-based industry-relevant analytics. It comprises methodological results such as analytical decomposition of the trend concept, including trend attributes (inherent characteristics) and various trend types and empirical results of detection and classification of global technology trends in the agricultural sector. The study makes a significant contribution to the development of a conceptual apparatus for trend analysis as a sub-area of Foresight methodology. The agricultural field is used to demonstrate the application the methodology. The empirical results can be applied by federal and regional authorities responsible for promoting development of the sectors to design relevant strategies and programmes, and by companies to set their long-term marketing and investment priorities.

In this paper we explore relationships between corruption perceptions and such characteristics as the size of shadow economy, GDP per capita, well-being, the Happy Planet Index (HPI), and quality of institutions. Special attention is paid to the comparison of transitional economies with countries that joined the European Union in 2004 and 2007, and developed countries. It is shown that irrespective of whether the economy is developed or transitional, negative dependence of corruption perceptions on shadow economy switches to positive if the size of the shadow economy increases over 15% of the official GDP. After the shadow economy passes 45%, the Transparency International Corruption Perceptions Index ceases to respond to growth of the shadow economy. Our estimates confirm that transition in countries is accompanied by growth of GDP per capita and a decrease in the level of corruption perceptions. For these reasons, transitional countries and countries where transition is over belongs to different clusters according to these indicators. This is not true for well-being and the HPI. It is not surprising that a regression analysis shows that "control of corruption" and "regulatory quality" are significant for reducing corruption perceptions both in transitional and other economies. It is interesting that "government effectiveness" and "voice and accountability" are significant only for transitional economies and insignificant in others. "Rule of law" and "political stability" are insignificant both in transitional and in developed countries

This paper addresses the determinants of migration between countries. Special emphasis is placed on which factors attract immigrants. This paper is the first to analyse this question in an integrated framework that takes into account the characteristics of both the origin and destination countries of migration. The findings confirm previous findings, however, in a broader and more compelling frame given the study’s unique dyadic approach to the analysis of migration patterns. Migrants are more attracted to countries with a common colonial history but, then, among these, prefer countries that offer the better living conditions and rule of law.

Purpose The present paper aims to determine the influence of various enterprise characteristics on job-related training. The paper focuses mainly on identifying the influence of a firm’s innovative activity, technological capacity for manufacturing and product market competition on its likelihood of having a training program and on training intensity. Design/methodology/approach The authors administered a firm-level survey to a sample of 2000 Russian enterprises. This survey includes questions about job-related training and key information about the companies’ activities. Probit estimates (including a multiple choice model) are used in the statistical analyses. Findings The results indicate that an enterprise’s provision of training is determined largely by firm-specific factors, such as its innovative activity, technical and technological state of manufacturing and product market competition. The authors adopt two widely used measures of training: incidence and intensity. Innovative activity and the technical and technological state of manufacturing are decisive factors in explaining a firm’s provision of training, as they have a strictly positive effect on both the incidence and the intensity of training. Product market competition has a positive effect on the incidence of training and a negative effect on the intensity of training. Originality/value This paper is original because it assumes that the process of deciding whether to implement a training program at an enterprise and the corresponding proportion of employees involved in training is built on the presupposition that the training intensity decision is made in two stages. This paper is the first to present estimates of job-related training intensity based on data from Russian enterprises.

Online reviews became one of the most effective tools that influence consumer behavior and level of sales. In this paper we consider determinants of online review rating. The study is based on more than three thousand online reviews from Russian consumers of durable goods (electronics and home appliances). It was found that there is a significant difference in the level of influence between new and old reviews. Moreover, the higher the total numbers of reviews available, the higher the number of reviews taken into account by a particular consumer. Another finding is that both average online rank and price of a product are positively correlated with variance of reviews on that product. Based on the differences in the effectiveness of information transmission about quality of products, products were divided into two categories: “experience” products and “search” products. At the last stage, we provide an econometric model that allows to explain not only dynamic but also the direction of consumers’ rank of a product.

This study examines the development of the board of directors institution in Russian companies. The purpose of the paper is to determine the stages of the evolution of the board role in Russia and to evaluate the further perspectives of this institution. Therewith we detect the stages according to the change of the board of directors role in Russian companies. We demonstrate the system of factors (institutional, legal, human, economic factors, and features of corporate sector) that influence the transformation of the board’s role. Studies of experts in the field of corporate governance and the updating of the corporate law form the informational base of the paper. Moreover we use the materials of interviews with the members of the boards conducted in spring-summer 2012.

The present study examines survey data from 45 countries by the means of factor and regression analyses in order to understand the nature and causes of anti-Americanism. Empirical results reveal a clear distinction between cultural and political anti-Americanism. The former involves negative attitudes towards American culture and its global spread, whereas the latter is specifically focused on disapproval of the U.S. foreign policies. The two forms of anti-Americanism also differ in their relationship to socioeconomic development. Cultural anti-Americanism is most widespread in countries with average levels of Human Development Index, whereas political anti-Americanism is stronger in the most developed societies. This study finds that Muslim societies are characterized by higher levels of both cultural and political anti-Americanism. On the whole, these findings indicate that anti-Americanism follows consistent country-level patterns and likely has universal roots which should be studied within a comparative framework.

The paper assesses the development of the market for navigation services and devices based on the results of a recently held Foresight exercise on monitoring of global technology trends. The future of the market for Global navigation satellite systems (GNSS) devices is largely influenced by grand challenges (i.e. lifestyle change, technical safety, urbanization, rural development, food security, etc.) that determine the pathway for extending use of GNSS signal in different sectors of the economy. Today, satellite positioning technology is used by transporters, carriers, motorists, surveyors, builders, etc. through a wide array of devices — like mobile phones or multimedia devices with built-in receiver modules. Different Foresight methods and tools were used for analyzing the market structure and volumes of navigation services and devices and to detect potential future market developments. The main technical characteristics of GNSS are compared in order to reveal their impact on the quality of the navigation signal essential for the end-users. Investigating the future dynamics of this market in Russia on the basis of expert estimations and governmental strategic documents, the authors conclude that the commercialization of GNSS in Russia is possible only in certain segments, mainly navigation modules for personal vehicles, surveying and mapping equipment as well as consumer electronics.

Professional associations in Russia are to some extent novices in contemporary professional regulation. Only small part of them can play significant role in enforcement of professional control (representing professional community in front of other stakeholders, adopting professional standards, ensuring market closure, protecting of prevalence of professional ethics etc.). Partially that comes from the lack of experience of self-regulation that professions have in the Russian history and sharp invasion of the global market in the 1990-es, partially that follows tradition of state predominance in economy and society. During the last two decades a mass of organizations arose in Russia calling themselves professional associations, guilds, societies and unions. The task to understand who they are, whether they can and they ought to represent professional community and what are their ways of professional self-regulation became now a pressing practical problem and an interesting research task. The object of this research is mapping the field of variety of non-government organizations that claim institutional control as professional associations in order to clarify the following issues: - What are the main forms of professional associations by their qualitative characteristics - What are their actual means and feasible opportunities to achieve professional control in their field of expertise or at least influence it – What are the main limits of professional self-regulation they dispose and whether there are any alternative forms of professional regulation in certain professional areas

This article describes the creation of a Russian-language version of the Contingencies of Self-Worth Scale (CSWS). We report the process and the three stages of adapting the questionnaire and report the results of the stage three version (N = 422); an internal consistency test (Cronbach's Alpha – from 0.67 to 0.84); item discrimination (0.55 to 0.86); retest reliability (0.54 to 0.79, p < 0.001); and construct validity. The analysis of the psychometric characteristics of the questionnaire confirmed the possibility of its appropriateness as a research tool to elicit the basis of self-esteem.

For a morphism of smooth schemes over a regular affine base we define functors of derived direct image and extraordinary inverse image on coderived categories of DG-modules over de Rham DG-algebras. Positselski proved that for a smooth algebraic variety $X$ over a field $k$ of characteristic zero the coderived category of DG-modules over $\Omega^\bullet_{X/k}$ is equivalent to the unbounded derived category of quasi-coherent right $\DD_X$-modules. We prove that our functors correspond to the functors of the same name for $\DD_X$-modules under Positselski equivalence.

Economic sanctions, like the most of political events involving numerous states, are almost always explicitly aimed to alter internal policies and affect domestic issues. Sanctions are not a discrete event, rather they are a long lasting insidious process. It is significant to consider not only the state of the country under sanctions or without them, but also the effect of the time under sanctions. Hence, the research question is as follows: How does cumulative effect of sanctions influence the dictators behavior in terms of repressions and co-optation? In order to find a feasible answer to that question, first, we build a theoretical model and draw empirical implications from it. The main argument that we develop in the paper is as follows. The overall effect of sanction is robustly important for the dictator, fostering repressions and co-optation (separately treated) as the ways of buttressing the regime legitimacy. Moreover, cumulative effect of sanctions (i.e. the influence of all the previous periods under sanctions) increases the levels of repressions with decreasing marginal effects.

This study questions a widespread opinion that Alexandrian scholars did not influence Homeric vulgate (or at least did not influence it substantially), because the overwhelming majority of their readings was  absent from the manuscript tradition of  The  Iliad. This opinion is based on the calculations of Alexandrian readings made by Thomas W. Allen, and they are demonstrably  in need of revision. If we also take into account not-attested Aristarchean readings that are cited in Martin L. West’s edition of The  Iliad,  there will  be a strong tendency for them to agree with vulgate variants.  All those  adjustments  may  seriously affect  the proportion of Aristarchus–vulgate discrepancies. Moreover, it is not impossible that our vulgate is generally identical to the Aristarchean edition of The Iliad.

This paper aims to contribute to the body of empirical studies that address the importance of investments in companies’ relationships and the way in which they influence value creation in the global economic crisis. We employ linear panel analysis using the Hausman–Taylor model to analyse panel data for companies from the five largest European countries in the period 2004–2011. Different types of exogenous and endogenous links which a company could have in different stages of the crisis are investigated. The findings suggest that there is a statistically significant and positive link between relational capital and a firm’s value. Moreover we identify several differences in the significance of the inputs during different crisis periods. The study provides both theoretical and practical insights into investments in intangibles for framing strategy decisions with a particular focus on the role of relational capital. This could provide scholars and practitioners with a working basis for understanding connections and the implications of strategizing in the context of a company’s networks.

The question whether visual working memory (VWM) stores individual features or bound objects as basic units is actively debated. Evidence exists for both feature-based and object-based storages, as well as hierarchically organized representations maintaining both types of information at different levels. One argument for feature-based storage is that features belonging to different dimensions (e.g., color and orientations) can be stored without interference suggesting independent capacities for every dimension. Here, whether the lack of crossdimensional interference reflects genuinely independent feature storages or mediated by common objects. In three experiments, participants remembered and recalled the colors and orientations of sets of objects. We independently manipulated set sizes within each feature dimension (making colors and orientations either identical or differing across objects). Critically, we assigned to-be-remembered colors and orientations either to same spatially integrated or to different spatially separated objects. We found that the precision and recall probability within each dimension was not affected be set size manipulations in a different dimension when the features belonged to integrated objects. However, manipulations with color set sizes did affect orientation memory when the features were separated. We conclude therefore that different feature dimensions can be encoded and stored independently but the advantage of the independent storages are mediated at the object-based level. This conclusion is consistent with the idea of hierarchically organized VWM.

The consequences of high divorce rates for intergenerational mobility depend on two factors. The first has been widely studied and regards the differing incidence of divorce according to socio-economic background. The second has been studied less and is the heterogeneity in the effects of divorce according to parental background. This paper investigates whether signs from earlier research that children from higher social backgrounds suffer more from divorce can indeed be interpreted as such. We follow a cohort of British children born in 1970 (N = 11,073) and look at how educational and occupational outcomes differ depending on family structure, socio-economic background, and the interaction between them. We improve on earlier studies by including a rich set of pre-divorce characteristics and are able to show that heterogeneity in the effects of divorce indeed exists and is not likely to be due to selection effects. Children whose parents are more highly educated have a larger ‘divorce penalty’ when it comes to educational and occupational attainment. A large part of the heterogeneity can be explained by the parents’ income at age 16, parental monitoring, the child’s participation in extra-curricular activities and his or her views regarding the benefits of education at age 16. The results suggest that, in contrast to the emphasis put in much recent research, divorce seems to have been a factor contributing to increased intergenerational mobility in the period under study.
