The abduction of women is closely connected with traditional or primitive societies. Anthropologists tie it with alternative marriage arrangements, characteristic of those systems where marriages are arranged by parents; historians tend to view the abduction of women as part of early history of developed nations, mostly the Middle Ages. In Russia, recent historiographical discussion of abductions always starts with descriptions of customary practices in Siberia to highlight the steppe and frontier experiences in the framework of colonization and underline ‘savage’ or ‘backwardness’ of Siberian populations. However, scholars almost never talk about the abduction of women within the European part. In this article, female abductions are analyzed within the framework of citizenship and modernization of the Russian Empire in the seventeenth and eighteenth centuries. It focuses on the notion of consent and how it contributed to the founding of a new social unit, that is the family, in which women and men acquired their rights and duties in relation to outside society and wider polity. The lack of consent jeopardized the legitimacy of such a union and compromized the citizenship status of its members. On its way to build the country as a modern empire, Russian authorities localized the abduction of women as a ‘customary’ practice of ‘backwards’ people to preserve the modern European core of the Empire.

We study Calabi-Yau threefolds fibered by abelian surfaces, in particular, their arithmetic properties, e.g., Neron models and Zariski density.

In this paper, we prove a kind of Abelian theorem for a class of stochastic volatility models \((X,V),\) where both the state  process \(X\) and the volatility process \(V\) may have jumps. Our results  relate  the asymptotic behavior of the characteristic function of \(X_{\Delta}\) for some \(\Delta>0\) in a stationary regime to the Blumenthal-Getoor indexes of the  L\'evy processes driving the jumps in \(X\) and \(V\). The results obtained are used to construct consistent estimators for the above Blumenthal-Getoor indexes  based on low-frequency observations of the state process \(X\). We derive the convergence rates for the corresponding estimator and show that these rates can not be improved in general.

It is well known that the Fano scheme of lines on a cubic 4-fold is a symplectic variety. We generalize this fact by constructing a closed p-form with p=2n-4 on the Fano scheme of lines on a (2n-2)-dimensional hypersurface Y of degree n. We provide several definitions of this form - via the Abel-Jacobi map, via Hochschild homology, and via the linkage class, and compute it explicitly for n = 4. In the special case of a Pfaffian hypersurface Y we show that the Fano scheme is birational to a certain moduli space of sheaves on a p-dimensional Calabi--Yau variety X arising naturally in the context of homological projective duality, and that the constructed form is induced by the holomorphic volume form on X. This remains true for a general non Pfaffian hypersurface but the dual Calabi-Yau becomes non commutative.

The spontaneous oscillatory activity in the human brain shows long-range temporal correlations (LRTC) that extend over time scales of seconds to minutes. Previous research has demonstrated aberrant LRTC in depressed patients; however, it is unknown whether the neuronal dynamics normalize after psychological treatment. In this study, we recorded EEG during eyes-closed rest in depressed patients (N = 71) and healthy controls (N = 25), and investigated the temporal dynamics in depressed patients at baseline, and after attending either a brief mindfulness training or a stress reduction training. Compared to the healthy controls, depressed patients showed stronger LRTC in theta oscillations (4–7 Hz) at baseline. Following the psychological interventions both groups of patients demonstrated reduced LRTC in the theta band. The reduction of theta LRTC differed marginally between the groups, and explorative analyses of separate groups revealed noteworthy topographic differences. A positive relationship between the changes in LRTC, and changes in depressive symptoms was observed in the mindfulness group. In summary, our data show that aberrant temporal dynamics of ongoing oscillations in depressive patients are attenuated after treatment, and thus may help uncover the mechanisms with which psychotherapeutic interventions affect the brain.

The last market crash of 2008-2009 showed that the construction sphere is one of the most fragile spheres to the crisis effect. The destructive effect of this crash was resulted in substantial decrease in mortgage lending, price index, capital investment, and in growth of the cost level. As the construction industry remains strategically important, the eruption of this sphere, which was facilitated by the crisis, might considerably harm Russian economy as a whole. However, lack of relevant studies leaves the main risk factor of Russian construction firms’ failure unexplored. The purpose of this study is to reveal the key determinants, which cause bankruptcy of Russian construction firms during the crisis period. Moreover, the article provides testing of applicability of accounting-based models to prediction of bankruptcy of these firms. The results show the validity of binary-choice logit and probit specifications with the highest classification accuracy of around 85%. In addition, the liquidity and profitability ratios were defined as superior insolvency factors for four years before a company files for bankruptcy.
