Working paper

This article examines the relation of two models of civil science in the early modern political literature: the rhetorical science of contingency (rhetorica primaria), and mathesis politica, associated with Descartes by some early Enlightenment authors. The authors analyze the reception of the rhetorical aspect of Hobbes’s civil science with a special focus on Vico’s criticism of Hobbes’s constructivist state model, showing how Vico counters the Hobbesian ‘protosociological’ style of theorizing with his own historical way of reflecting on the social and ‘open’ structure of political action.

The fake monster Lie algebra is determined by the Borcherds function Phi_{12} which is the reflective modular form of the minimal possible weight with respect to O(II_{2,26}). We prove that the first non-zero Fourier-Jacobi coefficient of Phi_{12} in any of 23 Niemeier cusps is equal to the Weyl-Kac denominator function of the affine Lie algebra of the root system of the corresponding Niemeier lattice. This is an automorphic answer (in the case of the fake monster Lie algebra) on the old question of I. Frenkel and A. Feingold (1983) about possible relations between hyperbolic Kac-Moody algebras, Siegel modular forms and affine Lie algebras.

Working paper

Using a large sample drawn from families in the Moscow and Moscow region which are part of the Russian RMLS longitudinal survey we observe clear links between measured 2D:4D digit ratios and a variety of life outcome measures, even with the inclusion of multiple controls. Contributing to existing empirical findings, we found statistically significant empirical associations of 2D:4D with higher educational attainment, occupational outcomes, knowledge of foreign language, smoking, engaging in sport activities and with some aspects of respondent's self-esteem. In general, the character of detected empirical associations are different for women and men, as it was documented in our previous studies.

Working paper

Is in utero exposure to testosterone (T), measured by the second to fourth digit ratio (2D:4D), associated with lifetime educational attainment? A growing body of work finds exposure to prenatal T to be associated with aggression, physical fitness, performance in computer science, and type of occupation. However, there has not yet been substantial research its relationship with lifetime educational outcomes. Using a large sample drawn from families in Moscow and in the Moscow region from the Russian Longitudinal Measurement Survey (RLMS), we observe clear links between measured 2D:4D and the levels of education obtained by men. Statistically significant positive associations between higher 2D:4D (lower prenatal T) and higher levels of education were found, using difference in means analysis and generalized ordered logit (gologit) regressions. These findings were also robust to using a different subsample. Weaker findings were seen for women. Since many of the earlier findings have shown the benefits of higher prenatal T for achievement, the current finding of a negative effect of prenatal T on educational attainment raises interesting issues about the ambiguous effects of prenatal T and the degree to which the traits it promotes interact with different tasks and social contexts.

Working paper

Exposure to prenatal androgens affects both future behavior and life choices. However, there is still relatively limited evidence on its effects on academic performance. Moreover, the predicted effect of exposure to prenatal testosterone (T) - which is inversely correlated with the relative length of the second to fourth finger lengths (2D:4D) - would seem to have ambiguous effects on academic achievement since traits like confidence, aggressiveness, or risk-taking are not uniformly positive for success in school. We provide the first evidence of a non-linear relationship between 2D:4D and academic achievement using samples from Moscow and Manila. We find that there is a quadratic relationship between high T exposure and markers of achievement such as grades or test scores and that the optimum digit ratio for women in our sample is lower (indicating higher prenatal T) than the average. The results for men are generally insignificant for Moscow but significant for Manila showing similar non-linear effects. Our work is thus unusual in that it draws from a large sample of nearly a thousand university students in Moscow and over a hundred from Manila for whom we also have extensive information on high school test scores, family background and other potential correlates of achievement. Our work is also the first to have a large cross country comparison that includes two groups with very different ethnic compositions.

Working paper

We construct an action of the braid group on n strands on the set of parking functions of n cars such that elementary braids have orbits of length 2 or 3. The construction is motivated by a theorem of Lyashko and Looijenga stating that the number of the distinguished bases for An singularity equals (n + 1)n−1 and thus equals the number of parking functions. We construct an explicit bijection between the set of parking functions and the set of distinguished bases, which allows us to translate the braid group action on distinguished bases in terms of parking functions.

This paper presents a set of drills that train students' competence in using the adjectives that belong to the semantic domain of FAR. The drills are based on and exemplify theoretical results of a study focusing around the comparison of synonymous adjectives across six languages and aim at granting students with a systematic and holistic picture of the domain in question. The training materials highlight the basic semantic parametres governing the correct lexical choice as well as the relevant distributional and grammatical patterns. Exemplified here are the drills for Russian and English languages. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica}

Working paper

We present a new combinatorial formula for Hall-Littlewood functions associated with the affine root system of type A~n−1, i.e. corresponding to the affine Lie algebra slˆn. Our formula has the form of a sum over the elements of a basis constructed by Feigin, Jimbo, Loktev, Miwa and Mukhin in the corresponding irreducible representation.Our formula can be viewed as a weighted sum of exponentials of integer points in a certain infinite-dimensional convex polyhedron. We derive a weighted version of Brion's theorem and then apply it to our polyhedron to prove the formula.

Euroregions is an important and quite popular mechanism of cross-border cooperation. Character of institutions development differs essentially between three groups of states, which use this mechanism: old members of the European Union; new members of the European Union (entered the EU after 2003); CIS members. This comparative research is concerned with the main circumstances of euroregions development in three areas noted above. The analyses show the fundamental differences between three Euroregion cases: Oresund, Pskov-Livonia and Dnieper. Those differences are noticeable in legislative basic, financing, cooperation issues, and even in four basic Euroregions principles realizing. Meanwhile we see that after fifteen years of copying the Euroregions in post-soviet countries the positive shifts occur in CIS members’ government perception and in the decision making process.

Working paper

The paper is based on the outcomes and inferences from the experiment with urban heterotopia found on the Manezhnaya square in Moscow. The main point of the experimental design (ethnomethodological in its intent) is to explore in vivo the heterotopical properties of the urban environment as the condition of this environment’s creativity and its interaction with the mobile actors. Creativity of the urban environment was interpreted as a particular kind of spatial order accumulating in counterfinal effects of collective behavior in the unique constellation --“heterotopia”. The flâneur was chosen as the most appropriate actor displaying the properties of an object and that of a receptive mobile interactant. The object of the experiment was the fragment of the metropolitan environment which combines the logic of the urban social organization (embodied in its concrete place) and the paralogy of the counterfinality of the mobilities inside this particular environment.Two modes of interaction were provoked in the experiment: first, intended, but unpurposive action observed by the passage through the ambiances of the specific fragment of the city by the flâneur, and focusing on his affective states during these actions (the affective profile of the place thus was achieved); and second, observing and mapping the flâneur’s movements as a purposive interaction with the same fragment of the environment, but in the form of dérive (observation of the movement by the means of movement). The end of the observation in movement was to focus on the flâneur’s movements and to depict his route through the observable details of the spatial/social order of the environment.

Last several decades have shown a steady broadening of national security issues’ spectrum along with an increase in the strictness of international competition driven by advances in high tech-nologies and other factors. National security agenda is nowadays comprised not only of defense issues per se, but also includes economic, social, cultural and other aspects. All this is strongly influenced by the technological trends and the very possession of critical technologies has be-come a pressing national security issue. Thus, we are witnessing a gradual convergence of na-tional security and technological agendas. Advocating a proactive approach to tackling national security risks of a technological nature, the authors make an attempt to outline the contemporary innovative methodology of assessing, harnessing and counteracting such risks. Their key rec-ommendation lies in the appeal for joining the forces of theorists and practitioners in the field of both national security and science, technology and innovation (STI) policy to overcome the cor-responding challenges.

Let M be a G2-manifold. We consider an almost CR-structure on the sphere bundle of unit tangent vectors on M, called the CR twistor space. This CR-structure is integrable if and only if M is a holonomy G2 manifold. We interpret G2-instanton bundles as CR-holomorphic bundles on its twistor space.

The objectives of the study were (a) to identify the reasons and concerns of those public administrators and marketing scholars who do not accept the usefulness of marketing in the public sector; (b) to deconstruct, comprehend, interpret, and critically appraise the current conceptualization of public sector marketing from the viewpoint of negativists identified in step (a); and (c) to reconstruct, redefine, reinterpret, and reoperationalize the current controversial conceptualization of public sector marketing into a new conceptualization in the context of park and recreation services. The critical theory approach to the study primary used non-empirical procedures data collection and analytic procedures which included investigative research, negative case analysis, and theoretical triangulation. These procedures were supplemented with empirical data collected from in-depth interviews with five scholars and with three parks and recreation managers. Results of the non-empirical procedures revealed the biased selective nature of the current conceptualization of public park and recreation marketing and the existence of alternative conceptualizations which have been ignored. The existing and alternative models were discussed with scholars and park and recreation managers. Support was found for the alternative models. From these data an alternative conceptualization of public park and recreation marketing was developed and named the concept of administered marketing. Implications for park and recreation managers are discussed. Directions for future research into the administratively managed park and recreation marketing concept are suggested.

The empirical literature assessing the connection between land rights, access to ﬁnance and investment activity has focused largely on actors that, for multiple reasons, might face difﬁculties accessing credit. Communities of small-scale farmers or poor urban households in developing countries, that is, may not be the best place to look for evidence as to whether more secure land rights are sufﬁcient to facilitate borrowing by providing borrowers with a collateralizable asset. We explore this relationship in a setting in which ﬁ nancial market frictions are apt to be less severe – i.e., among large, urban, industrial enterprises. Exploiting policy-induced variation across Russian regions, we use recently-collected survey data to show that private rights to land do indeed facilitate access to external ﬁnancing and promote investment. This ﬁnding is supplemented by additional survey evidence that points to private land serving as an important source of collateral.

We present a new direct logarithmically optimal in theory and fast in practice algorithm to implement the high order finite element method on multi-dimensional rectangular parallelepipeds for solving PDEs of the Poisson kind. The key points are the fast direct and inverse FFT-based algorithms for decomposition in eigenvectors of the 1D eigenvalue problems for the high order FEM. The algorithm can further be used for numerous applications, in particular, to implement the high order finite element methods for various time-dependent PDEs.

The notion of a (metric) modular on an arbitrary set and the corresponding modular space, more general than a metric space, were introduced and studied recently by the author [V.V. Chistyakov, Metric modulars and their application, Dokl. Math. 73 (1) (2006) 32–35, and Modular metric spaces, I: Basic concepts, Nonlinear Anal. 72 (1) (2010) 1–14]. In this paper we establish a fixed point theorem for contractive maps in modular spaces. It is related to contracting rather “generalized average velocities” than metric distances, and the successive approximations of fixed points converge to the fixed points in a weaker sense as compared to the metric convergence.

We examine a new general class of hazard rate models for survival data, containing a parametric and a nonparametric component. Both can be a mix of a time effect and (possibly time-dependent) marker or covariate effects. A number of well-known models are special cases. In a counting process framework, a general profile likelihood estimator is developed and the parametric component of the model is shown to be asymptotically normal and efficient. The analysis improves on earlier results for special cases. Finite sample properties are investigated in simulations. The estimator is shown to work well under realistic empirical conditions. The estimator is applied to investigate the long-run relationship between birth weight and later-life mortality using data from the Uppsala Birth Cohort Study of individuals born in 1915-1929. The results suggest a relationship that is difficult to capture with simple parametric specifications. Moreover, its shape at higher birth weights differs across gender.

We consider a generalization of the conjunction rule in the theory of imprecise probabilities. Note
that the conjunction rule, produced on credal sets, gives their intersection and is not defined if this
intersection is empty. In the last case the sources of information are called conflicting or contradictory.
Meanwhile, in the Dempster-Shafer theory it is possible to use the conjunction rule for conflicting
sources of information having as a result a non-normalized belief function that can be greater than
zero at empty set. We try to exploit this idea and introduce into consideration so called generalized
credal sets allowing to model imprecision (non-specificity), conflict, and contradiction in information.
Based on generalized credal sets the conjunction rule is well defined for contradictory sources of
information and it can be conceived as the generalization of the conjunction rule for belief functions.
We also show how generalized credal sets can be used for modeling information when the avoiding
sure loss condition is not satisfied, and consider coherence conditions and natural extension based on
generalized credal sets.
