Recovery after stroke relates tightly to the white matter integrity. Currently, the main methodology for non-invasive white matter integrity assessment is diffusion-weighted magnetic resonance imaging (DW-MRI), a state-of-the-art approach which is, however, prone to multiple limitations. Using DW-MRI, it was demonstrated that many pathways including corticospinal tract (CST) and corpus callosum contribute to structural brain reserve after stroke, but only a few of these tracts were found to be useful in the clinical practice. The most widely known measure is an asymmetry of the fractional anisotropy (FA) in CST at the level of the internal capsule, which could be used for predicting motor recovery in acute stroke. Recently, a new complementary motor component of the structural reserve, the so-called alternate motor fibers (AMFs), was proposed for motor recovery prognosis in stroke patients, and it was even reported to correlate with the effect of the transcranial direct current stimulation in chronic stroke. Here, we would like to point out a possible additional sensory interpretation of the AMF that appears plausible after taking into account technical limitations of DW-MRI approach, which may potentially give rise to different interpretations of the same results.

This research combines theories of civil society and local self-governance in describing citizen participation in solving neighborhood problems. Similar to neighborhood associations elsewhere, in Russia “organizations of territorial social selfgovernance” (TOS) have been formed to facilitate citizen participation in improving their communities. This research presents the first ever study of TOS across all Russian regions, drawing on a range of secondary data, lists of registered groups, and a phone survey of potential collaboration partners conducted in 2015. This paper explores the current state of these groups and their potential for collaboration with other civic organizations, government and business.

The present study analyzes Perm, Russia residential housing market supply focusing on sellers' heterogeneity. Many indicators of heterogeneity were consi- dered in the previous research, and all of them were proved to have a great impact on housing prices and time on the market. However, the gap exists in evaluating sellers’ pricing strategies in dynamics mostly because of unavailable data. Current study clears out the effect of time on price using data on asking price dynamics. We employ semiparametric sample selection estimation proce- dure which accounts for the unobserved property characteristics and non-random selection of objects out of the sample. We consider two main types of sellers: real estate agents and property owners, and show that real estate agents appear to be more impatient compared to property owners. Specifically, they set a lower asking price initially and are more likely to revise it over time if the object is not sold.

В этой работе мы предлагаем новый подход к прогнозированию спроса. Изучаемый рынок театральных услуг отличается тем, что наблюдаемый спрос ограничен вместимостью зала. В этом случае для получения несмещенных оценок параметров функции спроса необходимо учитывать его цензурированность. Присутствие потребительских сегментов с различными целями похода в театр и готовностью платить за отдельные характеристики постановки и показа определяет разнородность предпочтений потребителей на рынке. Мы предлагаем подход к оцениванию спроса, учитывающий его цензурированность и разнородность предпочтений. Функция оценивания базируется на идее деревьев регрессии и классификации и агрегирования бутстраповских предсказаний. Мы расширяем эту идею на случай наличия цензурированной зависимой переменной. Предлагаемый алгоритм предсказывает и объединяет предсказания отдельно для дискретной и непрерывной частей цензурированных данных. Мы демонстрируем более высокую предсказательную силу в терминах точности прогноза нашего алгоритма по отношению к прочим функциям оценивания, не учитывающим цензурирование или разнородность. Предлагаемый подход полезен для нахождения продуктовых сегментов и оптимального ценообразования.

Purpose – This study explores company strategies for intangibles. We investigate whether it is reasonable for companies to intensify intangibles when the current strategy is not intangible-intensive. This paper aims to elaborate a theoretical model to describe the strategic decision-making in companies.

Design/methodology/approach – We use the Bellman equation framework to find the conditions under which a change in strategy for intangibles is reasonable.

Findings – The results determine the parameters of returns on intangibles in different strategies, the optimal intangible stock and the influence of external economic shocks. The findings of our study demonstrate that many requirements have to be met to make intangible-intensive strategy beneficial for a company. Moreover negative shocks of crises force a company to postpone a new strategy on intangibles.

Practical implications – This research provides an insight into strategic behaviour of companies under uncertainty. The theoretical findings demonstrate under which conditions companies should decide to switch to a strategy more intangible-intensive. This model can be used to empirically test parameters of different investment strategies of companies using structural estimation techniques.

Originality/value – This work contributes to the theory of managerial economics giving closed form solutions for the dynamic optimization of company behaviour. The findings also show how this behaviour might change when economic crises are faced or expected.
