dc.description.abstract

value: The purpose of this article is the analysis of branding in Russia and the forecast of its further development. The essence of branding, according to the authors, is the development of the buyers’ positive conditional response to the goods offered by the specific manufacturer. In Russia, branding development has specific rules and features. It is noted that the issue of the branding formation and development, currently has not been studied in depth in Russia. The authors conducted a desk review of branding parameters in Russia. A basic feature of the development of Russian branding is that it has been revived after a significant break. It is noted that Russian branding has gone through several stages of development, each characterized by significant events. Th is article provides branding perspectives for individual sectors of the Russian economy. The conclusion is that the current economic and political difficulties negatively affect most sectors of the Russian economy and soon the negative effects will intensify. However, in the medium term, a negative impact of these factors is limited. Access to modern technologies and ideas through the Internet continues, and branding program will be considered a tool for solving social problems. Overall, despite the economic and political difficulties, through the action of the technological and social needs, the branding outlook is positive. Th e authors suggest the following areas for development in Russian branding: in the short-term patriotism; import substitution; branding of other markets; a confidence crisis in society; compensatory development of brands in the social sphere; change of the consumer generation; the further development of communication. The research is based on the PEST-analysis. Refs 47. Figs 5. Tables 5.

dc.description.abstract

value:
This paper reports on a study of the competency approach use for assessment and development of HR-managers in Russian companies, the most demanded functional competencies of these managers, and relevant problems of their professional growth and development.
In the empirical research the online survey was carried out in 2014-2015 with 74 employees of HR-departments of Russian companies. To identify the needs of the departments in professional growth and development of their managers, the model of professional competences for assessment and development was developed and then used in the questionnaire.
The research showed low level of HR-managers’ awareness of possibility to use competency models for professional development. Competency-based assessment of HR-managers is not wide-spread and is implemented only in large companies. In spite of it, the research demonstrated high value of the functional competencies of both strategic and tactical levels as fields of professional development of Russian HR-managers.
The study of competency model use for HR-managers assessment and development in Russian companies was first conducted. Authors were first to propose the three-level model of HR-managers’ functional competencies in the context of strategic partnership which helps to reveal distinctly the need and the requested content of professional development courses in the field.
Due to the pilot type of the study, completion and testing of the full version of the model developed as well as verification of the results obtained on the representative sample of Russian companies is recommended.
The competency model may be used for the creation of learning programs designed for Russian HR-managers. Conclusions of the research may help to develop practices of competency-based assessment in HR-departments as well as universities. Exploratory empirical research helped to detect the most essential functional competencies of HR-managers as well as problems of their professional growth and development. Studies conducted on the mentioned issues facilitate the development of HR professional communities, and the proposed model draws attention to raising the quality of professional development in the field.

dc.description.abstract

value:
The goal of this paper is to analyze the relationship between the managerial decisions in working capital management and the return on assets of Russian food companies.
Cash conversion cycle is chosen as a criterion of working capital management decisions effectiveness. The dependence of the return on assets both on cash conversion cycle and on each of its elements, and additionally, the dependence of cash conversion cycle on current ratio of companies belonging to food industry. The choice of industry is determined both by its importance for national economy and the large contribution of working capital management to the profit-ability growth of food companies.
The research is performed by means of regression analysis. The sample consists of 282 companies and the period of data collection is 2009-2013.
The inverse relationship is proven between the cash conversion as a whole and the return on assets, also between each element of cash conversion cycle (inventories, receivables, and payables) and the return on assets as well. This result differs from previous results (in earlier studies a direct relationship between payables and return on assets was revealed) and could be explained by specifics of business environment where Russian companies operate. The direct relationship between cash conversion cycle and current ratio is also revealed. Besides the margins for minimal and maximal cash conversion cycle are defined. Within these margins, companies are matching to the requirements of current ratio and thus, they can meet both the long-term and short-term managerial goals - value creation and sustainability.
The research findings can help to get deeper insight of trade policy and working capital management of Russian food companies. They also provide financial managers with information that may help them to reconsider their managerial decisions in a way that promotes better performance.
The paper considers the specifics of the industrial environment that affects financial decisions. It is important for the exploration of managerial decisions on working capital management.

dc.description.abstract

value:
The purpose of the article is to assess entrepreneurial spirit and entrepreneurial activity of students and to identify students’ needs in specific educational programs concerning the development of entrepreneurship projects in the innovative sphere and study the case of National Research University Higher School of Economics in Nizhny Novgorod (HSE NN).
The empirical study was conducted in three stages during 2014-2015, including desk study, interviews with experts and students survey. Authors adapted GEM and GUESSS questionnaires according to the aim to study students’ needs in entrepreneurship education in the innovative sphere. Questions added concern students’ needs in developing entrepreneurial competencies, skills, educational formats and topics of the entrepreneurship in the innovation sphere.
Findings show the entrepreneurial spirit and activity of the HSE NN students, their needs in special educational programs in entrepreneurship in the innovation sphere. Students are ready to start an entrepreneurial project only after acquiring some experience as employees. Findings indicate low entrepreneurial activity among HSE NN students. One of the main reasons for that is the shortage of the entrepreneurial competencies and skills among students. Low involvement of students in the current educational activities in the entrepreneurship is caused by low quality and effectiveness of them. It is offered, that curriculums for entrepreneurship and extracurricular activities should focus on entrepreneurship practices through the development of students’ projects. Findings reveal the most needed topics for studying the entrepreneurship in the innovation sphere, such as team formation, business-planning, market strategy of launching of the new product, depending on the specialization of students.
Research limitations appear in the focus on students of HSE NN. But the methodology could be used for the surveys of other Universities. It is worth mentioning the sample limitation. Due to the economic profile of the HSE NN, the research sample involves more students with economic specialization and less amount of students with mathematical and social specializations. The sample does not include technical specializations.
Russian and foreign universities could use the results in developing and improving educational activities for students in the entrepreneurship in the innovation sphere.
Originality of the paper concerns the adaptation of the questionnaire to the survey in entrepreneurship in the innovation sphere. It allows revealing students’ needs in the educational activities in innovation entrepreneurship.

dc.description.abstract

value:
This paper investigates one of the important characteristics of the corporate board – multiple directorships with a particular focus on directors' busyness. The paper analyses busyness criteria both for a board and directors, motives for multiple directors' positions for companies and board members, the relationship between board busyness and company's performance. The reputation and busyness hypotheses are analysed from perspective of boards multiple directorships impact on financial performance and value. Directors participation in several boards leads to their excessive busyness. It may be to the detriment of corporate performance, since due to relatively less time available those directors devote less efforts to their duties.
At the same time additional resources directors obtain from multiple positions on boards is important factor to enhance director's reputation.
In this paper the authors provide thorough literature review on the busyness of directors and boards, analysis of the relationship between directors' busyness and company's performance from perspective of two approaches - reputation hypothesis and busyness hypothesis.
This paper investigates the directors' busyness as a complex issue that has its specifics and implications for companies from developed and emerging markets. The value of the paper is that it provides deep analysis of the busyness and its effect on corporate performance results.
The authors find that directors' busyness needs further investigation in emerging markets, given the specifics of those markets, the scarce of professional directors at the labour market, the special role of board networks and other external resources directors could obtain through multiple directors positions for directors themselves and board reputation.
The main implication is that the paper articulates the directions for further research of this issue that should go beyond the hypotheses used in the existing sources, taking into account the specifics of emerging markets.

dc.description.abstract

value:
The purpose of the study was to conduct an analysis of the main researches on ecological entrepreneurship (ecopreneurship) to define the stages of its development, main trends and topical research areas.
Academic papers published in the peer-reviewed journals in the period from 1997 till 2015 were used to conduct the analysis. The papers were searched in the International data bases of articles, such as Scopus, Web of Science and EBSCO using the following key words: environmental entrepreneurship, green entrepreneurship, ecoentrepreneurship, ecopreneurship and green-green business. The articles, falling within the domain of the entrepreneurship and management, in which the ecological entrepreneurship is either the main topic of research or one of the components of the studied facts, were selected for the investigation objectives. The sources were distributed into the following sections: theoretical research and empirical research.
The most part of research in ecopreneurship may be characterized as empirical studies, based on the qualitative methods. The number of theoretical and conceptual studies of the ecopreneurship is significantly low. The number of papers discussing the empirical testing of the formulated hypotheses by the quantitative methods of analysis is very few. The analysis of the literature suggests that the development of the ecopreneurship theory is at the emerging stage of the scientific theory, which is characterized by formulating of the open matters, using qualitative methods for the empirical research, and by the assumptions about the development of the theory.
Only English-language publications, full texts of which were accessible in the International data bases Scopus, Web of Science and EBSCO, were used. The investigations of the external social and economic, political, legislative contexts, suppressing or encouraging the ecopreneurship intentions as well as the diversity of those conditions in different countries, were suggested as the trend for the future research.
The paper is the source of the systemic information about the current condition of the ecological entrepreneurship investigations and can be useful both for the researchers and for the ecopreneurs.

Business models (BM) are becoming one of the actively studied subjects in contemporary management
research, being highly demanded by both academic and professional communities. It
is assumed that BM innovation could serve as a crucial source of competitive advantage for
the company, that it much less expensive than new product launches or investment in new
market entering. Regardless the significant growth of publications in BM area many questions
still remain unanswered. Various researchers develop new approaches to BM analysis that are
aimed to better understand a company BM and also explore the mechanisms for its change and
improvement. This article offers a new approach to BM analysis that is based on value chains
and organizational networks theory. This approach is based on key tendencies in BM research
and has a number of specific features that differentiate it from the other approaches and make
it more adaptable and practically applicable in business.

This article examines the demographic, social and ethno-cultural processes in the European/Russian
North. Analyzing the content of the notion “Russian North” and historical reasons that led to its emergence,
it is shown that the centuries-old process of colonization of the Russian North in recent decades
has not only been completed, but the opposite process of decolonization has already begun. Along
with the loss of cultural attractiveness, the North of European Russia has also lost its social attractiveness
as a favorable job market that can ensure personal well-being and as a promising region where
social conditions can promote successful personal careers for its inhabitants. In the region there are
increased social and cultural risks that could lead to a profound imbalance in the region’s social development.
It is obvious that within the overall Arctic strategy a macro-regional strategy is needed that
can take full account of the historical, cultural and social resources of the Russian North as well as the
peculiarities of the social and cultural processes taking place there. Refs 28.

В статье рассматриваются демографические, социальные и этнокультурные процессы,
происходящие на европейском/Русском Севере. Анализируется содержание понятия «Русский
Север» и исторические причины, которые привели к его появлению. Показано, что многовековой процесс колонизации Русского Севера в последние десятилетия не только завершился,
но начался процесс деколонизации. Наряду с утратой культурной привлекательности европейский север России утратил и социальную привлекательность как выгодный рынок труда,
где можно обеспечить личное благосостояние, и как перспективный регион, где социальные
условия позволяют с успехом делать личную карьеру. В регионе происходит нарастание социальных и культурных рисков, которые в перспективе могут привести к глубоким диспропорциям в социальном развитии названного региона. Очевидно, что в рамках общей Арктической
стратегии необходима разработка макрорегиональной стратегии, которая бы в полной мере
учитывала исторические, культурные и социальные ресурсы Русского Севера и специфику социальных и культурных процессов, происходящих в регионе. Библиогр. 28 назв.

This article examines the main aspects of interaction between municipal candidates and residents of
Kanonersky island in St. Petersburg. The study was conducted between the summer and autumn of
2014, during the the pre-election campaign for municipal offices. The author seizes the period of active
political struggle between the more rigid ‘system’ authorities and more active ‘non-system’ opposition.
Political communication is considered from a relational perspective that helps to identify cultural aspects
of interaction. Using the works of the relational sociologist A. Mische, we highlight a number of
conversational mechanisms which were used by opponents during the political competition. Findings
are based on qualitative analysis of interviews, social networks and observations obtained in the course
of empirical research. Refs 9. Figs 2.

This article examines the theoretical and methodological basis of the interrelated and complex notion
of the person as a whole and also examines the practice of preserving his health. Man as an whole is
characterized by fundamentally different layers of phenomena — from the material to various manifestations
of mental and social qualities. All parameters of this wholeness and the characteristics of
their interactions can be either in a state of normality (health) or its violation it (the state of disease).
Defi nitions and characteristics of health depend on human interaction with social environments, and
are considered in a continuum: from an arbitrarily low level (objective) to provisionally higher one
(subjective). The subjective position of man includes awareness of health as a basic value of life, an
awareness which Russians have historically underdeveloped. The capacity for self-transformation is
the most important characteristic of wholeness, which can aff ect both prevention and the course of
disease itself.
The process of matching the composite elements of wholeness with objective requirements often
extends over the entire period of a person’s life and is refl ected in the success of adequate social inclusion.
The success of such inclusion contributes to a balance in the activities of medical and representatives
of the human sciences, as well as to the productiveness of the population’s orientation towards a
healthy lifestyle and various risks and threats to its preservation. Refs 16.

В статье рассматривается теоретико-методологическое обоснование взаимоотношений
сложившихся концепций человека как целостного образования и практик поддержания его
здоровья.
Человек как целостность характеризуется наличием принципиально различающихся слоев
явлений — от материальных до различных проявлений психики и социальных качеств. Все
параметры целостности, характеристики их взаимодействия могут находиться либо в состоянии нормы (здоровья), либо выходить за ее пределы (состояние болезни). Здоровье зависит от
взаимодействия человека с социальной средой и рассматривается в континууме — от условно
нижнего (материального, объективного) до условно верхнего (субъективного). К субъективной позиции человека относится осознание здоровья в качестве базовой жизненной ценности,
которая у россиян недостаточно сформирована. Способность к самоизменениям — важнейшая характеристика целостности, которая может влиять как на превенцию, так и на само течение болезни.
Процесс согласования компонента целостности с объективными требованиями часто растягивается на весь период жизни человека и выражается в успешности включенности его в социальную среду. Успешности такого включения способствует баланс в деятельности медиков
и представителей гуманитарного знания, занимающихся поддержанием здоровья населения,
а также выработка у населения ориентации на здоровый образ жизни и профилактику различных рисков и угроз собственному здоровью. Библиогр. 16 назв.

The image, i.e. perception of the social services’ activities supporting population is one of the important
aspects of functioning of such organizations. The aim of the image formation is creating,
maintaining and strengthening positive public opinion concerning the system of social protection of
population and the quality of social services. The purposeful formation of positive image becomes an
essential task for social services and experts since it defines the degree of public confi dence in the state.
The article presents the analysis of the public social services’ image through the lens of the trust
factor. The authors identify the following indicators to determine the level of confidence: evaluation of quality of services by population, demand for various types of social services, confidence of the interaction
between citizens and state social services’ experts.
In order to identify the evaluation given by St. Petersburg residents to the quality of received services
in the city social and in-demand services, the SPSU opened Resource Center “Center for Sociological
and Internet Research” has conducted phone surveys in July, 2012 and repeatedly in summer of
2013. 1005 respondents participated in the 2012 phone survey, and 1002 — in 2013. The unified tool

Одним из важных аспектов функционирования в обществе социальных организаций, оказывающих поддержку населению, является имидж, т. е. восприятие их деятельности. Цель формирования имиджа — создание, поддержание и усиление позитивного общественного мнения о системе социальной защиты населения, качестве социальных услуг. Целенаправленное
формирование позитивного имиджа становится для социальных организаций и специалистов
важной задачей, так как он определяет степень доверия населения к государству.
В статье имидж государственных социальных служб анализируется через фактор доверия.
Авторы выделяют следующие индикаторы для определения уровня доверия: оценка населением качества оказываемых услуг, востребованность различных видов социальных услуг, доверительность взаимодействия граждан и специалистов государственных социальных служб.
С целью выявления оценки жителями Санкт-Петербурга качества полученных в городских
социальных службах услуг и востребованности услуг, в июле 2012 г. и повторно летом 2013 г.
Ресурсный центр СПбГУ «Центр социологических и Интернет-исследований» провел телефонные опросы. В 2012 г. в телефонном опросе участвовали 1005 человек, в 2013 г. — 1002 человека. В опросах использован единый инструментарий (вопросник, разработанный авторами

title: The Immediate Tasks of sociological construction proper (from the lectures by A. S. Lappo-Danilevsky)

dc.description.abstract

value:
On the basis of the manuscript Scientifi c bases of sociology in their historical development by Aleksandr
Sergeyevich Lappo-Danilevsky (1863-1919), Member of the Academy of Sciences, this article attempts
a reconstruction of his views on current problems of contemporary social science. In his understanding
of sociology, Lappo-Danilevsky relied on the teachings of Russian Neo-Kantians (A. I. Vvedenskii)
trying to resolve the problem of ‘another self ’ as well as the tradition of German Neo-Kantians (Baden
and Marburg schools).
Among the ‘immediate tasks of sociological construction’ he singled out epistemological and
historical trends. The epistemological direction is most fully embodied in neo-Kantian sociology. The
historical direction moved closer to cultural history and ethnography. Considering the epistemological
interpretation of social phenomena to be the most promising branch of sociology, in particular, the
version of the study of “pure forms of sociation” that Georg Simmel had proposed, Lappo-Danilevsky
as a professional historian recognized the importance of historical sociology. The epistemological and
historical trends in many respects duplicate the methodological separation of the sciences, which had
been proposed by German Neo-Kantians. Thus, the epistemological approach adopts a nomothetic
point of view, while the historic approach an ideographic one. In general, Lappo-Danilevsky stuck to a
moral interpretation of social relations. Without recognition of the psychic life of another person there
can be no social relationships or social order, but recognition is the result of the compulsory force of
«moral sense», referring to the other person as an end in itself, not only as a means. The social world
thus turns out to be the ‘kingdom of ends’ of which Kant wrote. The article quotes from a manuscript
of Lappo-Danilevsky, which allows one to form a fuller picture of his sociological heritage. Refs 5.

В статье на основе рукописи академика Александра Сергеевича Лаппо-Данилевского
(1863–1919) «Научные основы социологии в их историческом развитии» предпринимается попытка реконструкции взглядов ученого на актуальные задачи современной ему социологической науки. В своем понимании социологии Лаппо-Данилевский опирался как на учение русских кантианцев (А. И. Введенский), пытавшихся решить проблему «чужого я», так и на традиции немецкого неокантианства (баденской и марбургской школ). Среди «очередных задач
социологического построения» он выделял теоретико-познавательное и историческое направления. Теоретико-познавательное направление полнее всего воплотилось в неокантианской
социологии. Историческое же направление сближалось с историей культуры и этнографией.
Считая гносеологическую интерпретацию социальных явлений наиболее перспективным разделом социологии, в частности, в той версии изучения «чистых форм социации», которая была
предложена Г. Зиммелем, Лаппо-Данилевский как профессиональный историк признавал значение исторической социологии. Теоретико-методологическое и историческое направления во
многом дублировали то методологическое разделение наук, которое было предложено немецкими неокантианцами. Так, в гносеологическом подходе реализовалась номотетическая точка
зрения, а в историческом — идиографическая. В целом, Лаппо-Данилевский придерживался
моральной интерпретации социальных отношений. Без признания чужой душевной жизни
невозможны ни общественные отношения, ни социальный порядок, но само это признание
является результатом принудительной силы «нравственного чувства», относящегося к другому человеку как цели самой по себе, а не только как к средству. Социальный мир, таким
образом, оказывается «царством целей», о котором писал еще И. Кант. В статье приводятся
выдержки из рукописи Лаппо-Данилевского, позволяющие полнее представить его социологическое наследие. Библиогр. 5 назв.

This article examines the discourses of the senior citizens in modern Russia, represented by power
and society. The materials the author has used include offi cial documents, statistics and sociological
research. The official discourse (e.g. policy in relation to senior citizens) mostly shows progress in
national social policy. In public discourse gerontophobia and ageism can be found. The comparative
analysis of both discourses (offi cial and public) shows manipulation with positive results carried out
by officials, on the one hand, and the actual expulsion of “third age” citizens out of the scope of employment
on the other. This “expulsion” is not criticized in public discourse in general, as, in this case,
the concepts of “old age” and “retirement age” with the resultant “natural” change of status go hand in
hand. Refs 15.

dc.description.abstract

value:
One of the elements of the culture of consumer society is the myth of female beauty. According to this
myth, female social self-confi dence is achieved through beauty which is not an inborn characteristic
but a result of active and skillful consumer behavior in the market of the beauty industry. The strategy
of the struggle for beauty manifests itself in different forms, among which an important place is held by
the priority of decorative features in relation to functionality. This study is based on the concept of social
drama. The presentation of femininity occurs in the context of everyday and festive performances
in which appearance is transformed in a costume that provides performance of freely chosen or prescribed
roles. This model was tested in the empirical study of students in St. Petersburg. Refs 8. Figs 2.

место занимает приоритет декоративности по отношению к функциональности. В основе исследования лежит концепция социальной драматургии. Презентация женственности происходит в контексте повседневных и праздничных спектаклей, в которых внешность превращается
в костюм, обеспечивающий исполнение свободно выбранной или предписанной роли. Данная

dc.description.abstract

value: A novel fully automated effervescence-assisted switchable solvent-based liquid phase microextraction procedure has been suggested. In this extraction method, medium-chain saturated fatty acids were investigated as switchable hydrophilicity solvents. The conversion of fatty acid into hydrophilic form was carried out in the presence of sodium carbonate. The injection of sulfuric acid into the solution decreased the pH value of the solution, thus, microdroplets of the fatty acid were generated. Carbon dioxide bubbles were generated in-situ, and promoted the extraction process and final phase separation. The performance of the suggested approach was demonstrated by the determination of ofloxacin in human urine samples using high-performance liquid chromatography with fluorescence detection. This analytical task was used as a proof-of-concept example. Under the optimal conditions, the detector response of ofloxacin was linear in the concentration ranges of 3·10(-8)-3·10(-6) mol L(-1). The limit of detection, calculated from a blank test based on 3σ, was 1·10(-8) mol L(-1). The results demonstrated that the presented approach is highly cost-effective, simple, rapid and environmentally friendly.

Features of this approach, providing numerical estimates of the parameters are particularly useful in solving the prob- lems of designing space manipulators that require a higher degree of reliability performance. This procedure can also be used in other prac- tice areas, such as analysis of indirect signs of corruption in the socio- economic, 'nancial, military, geopolitical and other structures.

dc.description.abstract

value: The problem of estimating the coordinates of a moving object based on visual data arises in numerous applications, starting from robotic and ending with the consumer market of portable devices. Traditional algorithms for solving this problem require either additional devices or significant constraints on the possible motion of the object. In this work, we present a new approach to tracking the object that lets us estimate its position under sufficiently general conditions. The method is based on randomizing the camera location independently of the object’s motion; since the test disturbance we choose is independent, it lets us construct a feasible iterative pseudogradient estimation algorithm.

value: The simple and easy performed automated method for the IR determination of petroleum products (PP) in water using extraction-chromatographic cartridges has been developed. The method assumes two stages: on-site extraction of PP during a sampling by using extraction-chromatographic cartridges and subsequent determination of the extracted PP using sequential injection analysis (SIA) with IR detection. The appropriate experimental conditions for extraction of the dissolved in water PP and for automated SIA procedure were investigated. The calibration plot constructed using the developed procedure was linear in the range of 3-200 μg L(-1). The limit of detection (LOD), calculated from a blank test based on 3σ was 1 µg L(-1). The sample volume was 1L. The system throughput was found to be 12 h(-1).

dc.description.abstract

value: We reconstructed the spatial distribution of eclogites in the cratonic mantle based on thermobarometry for ~ 240 xenoliths in 4 kimberlite pipes from different parts of the Slave craton (Canada). The accuracy of depth estimates is ensured by the use of a recently calibrated thermometer, projection of temperatures onto well-constrained local peridotitic geotherms, petrological screening for unrealistic temperature estimates, and internal consistency of all data. The depth estimates are based on new data on mineral chemistry and petrography of 148 eclogite xenoliths from the Jericho and Muskox kimberlites of the northern Slave craton and previously reported analyses of 95 eclogites from Diavik and Ekati kimberlites (Central Slave). The majority of Northern Slave eclogites of the crustal, subduction origin occurs at 110–170 km, shallower than in the majority of the Central Slave crustal eclogites (120–210 km). The identical geochronological history of these eclogite populations and the absence of steep suture boundaries between the central and northern Slave craton suggest the lateral continuity of the mantle layer relatively rich in eclogites. We explain the distribution of eclogites by partial preservation of an imbricated and plastically dispersed oceanic slab formed by easterly dipping Proterozoic subduction. The depths of eclogite localization do not correlate with geophysically mapped discontinuities. The base of the depleted lithosphere of the Slave craton constrained by thermobarometry of peridotite xenoliths coincides with the base of the thickened lithospheric slab, which supports contribution of the recycled oceanic lithosphere to formation of the cratonic root. Its architecture may have been protected by circum-cratonic subduction and shielding of the shallow Archean lithosphere from the destructive asthenospheric metasomatism.

This paper presents new data on geochemistry of rare-earth and high-field-strength elements in
the upper mantle peridotite (spinel lherzolites) and pyroxenite (amphibole clinopyroxenites, garnet
clinopyroxenites, websterites, and garnet websterites) xenoliths collected from Quaternary volcanoes
of the north-western part of Spitsbergen Island, Svalbard Archipelago. The fractionating of HFSE in
the peridotites and pyroxenites, and the effect of temperature on the equilibration distribution of these
elements between minerals of spinel lherzolites have been investigated based on geochemical features
of rocks and minerals, obtained by ICP MS and SIMS. It has been concluded that fractionation of Nb,
Ta, Zr, Hf, and Ti occurs in the upper part of the continental lithospheric mantle under the conditions
that exist at depth corresponding to the Moho discontinuity (at the temperature from 730 to 1180 °C
and pressures from 1.3 to 2.7 GPa). These conditions correspond to those of the phase transition of
spinel peridotites into garnet peridotites in the CMAS systems. It is most likely that the degree of partial
melting and the thermodynamic conditions of this process are the main factors regulating fractionation
of HFSE. The fractionation of these elements in the mantle of north-west Spitsbergen is noticeably
different than in the mantle beneath Early Precambrian cratons.

dc.description.abstract

value: Electrical neuromodulation of lumbar segments improves motor control after spinal cord injury in animal models and humans. However, the physiological principles underlying the effect of this intervention remain poorly understood, which has limited the therapeutic approach to continuous stimulation applied to restricted spinal cord locations. Here we developed stimulation protocols that reproduce the natural dynamics of motoneuron activation during locomotion. For this, we computed the spatiotemporal activation pattern of muscle synergies during locomotion in healthy rats. Computer simulations identified optimal electrode locations to target each synergy through the recruitment of proprioceptive feedback circuits. This framework steered the design of spatially selective spinal implants and real-time control software that modulate extensor and flexor synergies with precise temporal resolution. Spatiotemporal neuromodulation therapies improved gait quality, weight-bearing capacity, endurance and skilled locomotion in several rodent models of spinal cord injury. These new concepts are directly translatable to strategies to improve motor control in humans.

Editors: Leon Petrosjan and Vladimir Mazalov
Book Description:
This book brings together papers of well-known specialists in game theory and adjacent problems. It presents the basic results in dynamic games, stochastic games, applications of game theoretical methods in ecology and economics and methodological aspects of game theory.
Special attention was given to problems in dynamic games under partial information and to the development of numerical methods for high-dimensional games (there is an increasing focus on this arena as recent theory is leading to solution methods for problems which were heretofore quite intractable). The interdisciplinary aspects touched upon were related to dynamical systems via replicator dynamics, with probability (measure-valued processes), with statistical mechanics (kinetic equation, non-equilibrium behaviour), with max-plus (or tropical, or idempotent) mathematics.
In this volume, we publish the review of Martin Shubik (The Present and Future of Game Theory) and the contributions presenting extending versions of the talks given at the workshop "Game Theory for Finance, Social and Biological Sciences", held in Warwick 14-17 of April 2010. The conference was exclusively marked by a rare natural event: the eruption of an Icelandic volcano Eyjafjallajökull, which blocked the functioning of most of the airlines, turning the way back for many participants to an adventurous enterprise.

dc.description.abstract

value:
Arctic soils contain large amounts of organic matter
which, globally, exceed the amount of carbon stored in
vegetation biomass and in the atmosphere. Recent studies
emphasise the potential sensitivity for this soil organic matter
(SOM) to be mineralised when faced with increasing ambient
temperatures. In order to better refine the predictions
about the response of SOM to climate warming, there is a
need to increase the spatial coverage of empirical data on
SOM quantity and quality in the Arctic area. This study provides,
for the first time, a characterisation of SOM from the
Gydan Peninsula in the Yamal Region,Western Siberia, Russia.
On the one hand, soil humic acids and their humification
state were characterised by measuring the elemental
composition and diversity of functional groups using solidstate
13C-nuclear magnetic resonance (NMR) spectroscopy.
Also, the total mineralisable carbon was measured. Our results
indicate that there is a predominance of aliphatic carbon
structures, with a minimal variation of their functional-group
composition both regionally and within soil depth. This vertical
homogeneity and low level of aromaticity reflects the
accumulation in soil of lowly decomposed organic matter
due to cold temperatures. Mineralisation rates were found to
be independent of SOM quality, and to be mainly explained
solely by the total carbon content. Overall, our results provide
further evidence on the sensitivity that the soils ofWestern
Siberia may have to increasing ambient temperatures and
highlight the important role that this region can play in the
global carbon balance under the effects of climate warming.

value: Coupling of the palladium-bis(isocyanide) complexes cis-[PdCl2(CNR)2] (R = 2,6-Me2C6H3 1, 2-Cl-6-MeC6H3 2) with benzene-1,3-diamine (BDA1) leads to the diaminocarbene species cis-[PdCl2(CNR){C(NHR)═NH(1,3-C6H4NH2)}] (5 and 6, respectively). In this reaction, BDA1 behaves as a monofunctional nucleophile that adds to one of the RNC ligands by one amino group. By contrast, the reaction of 1 and 2 with benzene-1,4-diamine (BDA2) involves both amino functionalities of the diamine and leads to the binuclear species [cis-PdCl2(CNR){μ-C(NHR)═NH(1,4-C6H4)NH═C(NHR)}-(cis)-PdCl2(CNR)] (6 and 7) featuring two 1,4-bifunctional diaminocarbene ligands. The reaction of cis-[PdCl2(CNR)2] (R = cyclohexyl 3) with either BDA1 or BDA2 does not afford any isolable carbene derivatives. The most versatile chemistry was observed when 1–3 were treated with benzene-1,2-diamine (BDA3) and the relevant substituted 1,2-diamines, viz., 4,5-dimethylbenzene-1,2-diamine (BDA4) and 4,5-dichlorobenzene-1,2-diamine (BDA5). The addition of these diamines brings about the formation of the monocarbene cationic complexes cis-[PdCl(CNR){C(NHR)═NHC6H2X2NH2}]Cl (X = H, Me, Cl) (8–16), the Chugaev-type C,C-bound bis-carbenes cis-[PdCl2{C(NHR)═NHC6H2X2NH═C(NHR)}] (17, 18), and the bis(C,N-chelated)carbene complexes cis-[Pd{C(NHR)═NHC6H2X2NH2}2]Cl2 (19–24). All prepared complexes (with the exception of 17 and 18) were isolated as colorless or pale yellow solids and characterized by elemental analyses (C, H, N), HRESI±-MS, IR, 1H and 13C{1H} NMR spectroscopies, and 4, 7, 13, 16, and 24 by X-ray diffraction. Complexes 17 and 18 were characterized by HRESI±-MS and IR spectroscopy, and their structures were established by X-ray crystallography.

Three new iminium salts [H2N]C(R)ON]C(R0)NH2](p-TolSO3)$½H2O ([1e3](p-TolSO3)$½H2O; R/
R0 ¼ NMe2/PhCH2 1, NMe2/p-BrC6H4 2, N(CH2)5/p-BrC6H4 3) were synthesized via ZnII-mediated
amidoxime-cyanamide coupling and their solid structures were studied by X-ray diffraction. Solution
structure and conformational changes of [1e3](p-TolSO3)$½H2O were studied by dynamic NMR. The
obtained quantitative data were supported by DFT calculations. All the obtained results help to understand
the relative stability of the salts [H2N]C(R)ON]C(R0)NH2](X) (R ¼ NAlk2, Alk, Ar) and give a
further insight into the mechanism of ZnII-mediated generation of 1,2,4-oxadiazoles. The electron
delocalization and sesquialteral bonds in the [H2N]C(NR2)ON]C(R0)NH2]þ system was recognized by
estimation of values of activation energy barriers (14e18 kcal/mol by DNMR and 16e17 kcal/mol by DFT
calculations) for the rotation around the CN bonds for the NR2 groups and inspection of the solid-state Xray
data along with the Wiberg bond indices (intermediate single/double bond order for the CN distances).
This electron delocalization is responsible for the stabilization of the positively charged iminium
cation. The moderate strength hydrogen bonding between the oxime N atom and the ¼NH2 group, which
is verified from the X-ray, DNMR experiments, and by using quantum chemical calculations, stabilizes the
iminium salt, but it is still weak to prevent the heterocyclization. Theoretical calculations of the heterocyclization
of [H2N]C(R)ON]C(R0)NH2]þ to 1,2,4-oxadiazoles demonstrated that it is kinetically hindered
to a greater extent for R ¼ NAlk2 and this explains their lower reactivity as compared to the
iminium salts with R ¼ Alk, Ar.

dc.description.abstract

value: The catalytic activity of aqua complexes of the group III metals [M(H2O)(n)](3+) (M = Ga, In, Sc, n = 6; M = Y, n = 8; M = La, n = 9) towards the oxidation of olefins with H2O2 was investigated in detail by theoretical (DFT) methods. It was predicted and then confirmed in a preliminary experiment that these complexes formed from simple soluble salts in aqueous medium are able to efficiently catalyse the olefin oxidation. The reaction occurs via two competitive reaction channels which are realized concurrently, i.e. (i) hydroperoxidation of the allylic C atom(s) via a radical Fenton-like mechanism involving HO. radicals and leading to alkyl hydroperoxides ROOH and (ii) epoxidation of the C=C bond through a one-step mechanism involving oxygen transfer from the hydroperoxo ligand in an active catalytic form [M(H2O)(n-k)(OOH)](2+) (M = Ga, In, Y, La, k = 2; M = Sc, k = 1) to the olefin molecule and leading to epoxides and/or trans-diols. Other concerted and stepwise mechanisms of the epoxidation were also considered but found less favourable.


title: PdII-mediated integration of isocyanides and azide ions might proceed via formal 1,3-dipolar cycloaddition between RNC ligands and uncomplexed azide

value: Haukka, M

value: Reaction between equimolar amounts of trans-[PdC(PPh3)(2)(CNR)][BF4] (R = t-Bu 1, Xyl 2) and diisopropylammonium azide 3 gives the tetrazolate trans-[PdCl(PPh3)(2)(CN(4)t-Bu)] (67%, 4) or trans-[PdCl(PPh3)(2)(CN(4)Xyl)] (72%, 5) complexes. 4 and 5 were characterized by elemental analyses (C, H, N), HRES1(+)-MS, H-1 and C-13{H-1} NMR spectroscopies. In addition, the structure of 4 was elucidated by a single-crystal X-ray diffraction. DFT calculations showed that the mechanism for the formal cycloaddition (CA) of N-3(-) to trans-[PdCl(PH3)(2)(CNMe)](+) is stepwise. The process is both kinetically and thermodynamically favorable and occurs via the formation of an acyclic NNNCN-intermediate. The second step of the formal CA, i.e. cyclization, is rate Limiting. Despite the fact that the substitution of CNMe by the N-3(-) Ligand is slightly thermodynamically favorable, we were unable to find paths on the potential energy surface for hypothetical CA between uncomplexed isocyanide and palladium-bound azide. Thus, we believe that the experimentally observed palladium tetrazolate complexes are, in fact, generated from the negatively charged uncomplexed azide and the positively charged metal-bound isocyanide species, and this reaction path is favorable from the viewpoint of Coulomb attraction.

title: Fine-tuning halogen bonding properties of diiodine through halogen–halogen charge transfer – extended [RuĲ2,2′-bipyridine)ĲCO)2X2]·I2 systems (X = Cl, Br, I)

value:
The current paper introduces the use of carbonyl containing ruthenium complexes, [RuĲbpy)ĲCO)2X2] (X =
Cl, Br, I), as halogen bond acceptors for a I2 halogen bond donor. In all structures, the metal coordinated
halogenido ligand acts as the actual halogen bond acceptor. Diiodine, I2, molecules are connected to the
metal complexes through both ends of the molecule forming bridges between the complexes. Due to the
charge transfer from Ru–X to I2, formation of the first Ru–X⋯I2 contact tends to generate a negative charge
on I2 and redistribute the electron density anisotropically. If the initial Ru–X⋯IA–IB interaction causes a notable
change in the electron density of I2, the increased negative charge accumulates on the second iodine,
IB. The increased negative charge on IB reduces its ability to act as a halogen bond donor. With the
[RuĲbpy)ĲCO)2Cl2] complex, the electron density of the I2 molecule remains isotropic and it acts as a symmetrical
halogen bond donor for two metal complexes. With [RuĲbpy)ĲCO)2Br2] and [RuĲbpy)ĲCO)2I2], the
Ru–X⋯IA–IB⋯X–Ru bridges are unsymmetrical with a stronger and shorter Ru–X⋯IA contact and a weaker
and longer Ru–X⋯IB contact. In these cases, the negative charge is accumulated on the more weakly
bonded IB atoms. QTAIM calculations were used to analyze the strength of the interactions and charge distribution
in the metal complex and I2 molecule in detail. In accordance with the experimental data, the
QTAIM analyses show that the charge difference between the two ends of the I2 molecule is increased in
the order Ru–Cl⋯I2 < Ru–Br⋯I2 < Ru–I⋯I2.

value: Gobble Chase, Chickos James

value: Samarov Artemiy A., Verevkin Sergey P.

value: The vaporization enthalpy of imidazo[1,2-a]pyrazine is evaluated by correlation gas chromatography using two sets of standards and by transpiration. Vaporization enthalpies were evaluated using heterocyclic standards with dipole moments that vary from 0 to 3.0 D and using standards with dipole moments > 3.0 D. A value of (70.7 ± 1.0) kJ·mol−1 measured by transpiration compares to (67.9 ± 1.4) kJ·mol−1 measured by correlation gas chromatography using standards characterized by dipole moments > 3.0 D. The results suggest that imidazo[1,2-a]pyrazine is a member of this series of compounds whose vaporization enthalpies exceed those less polar heterocycles by a fairly constant amount, (6.9 ± 0.3) kJ·mol−1,in this case by (5.9 ± 3.0) kJ·mol−1 using the less polar heterocycles. The crystal structures of phthalazine, another member of the polar series, and of imidazo[1,2-a]pyrazine were determined to examine whether π−π stacking, present in the solid state of two other members of the polar series, was a characteristic of this series. If present in the liquid, π−π stacking could offer a possible explanation for the vaporization enthalpy differences observed. The sublimation enthalpy of imidazo[1,2-a]pyrazine was also evaluated.

value: The nitrile complexes trans-[PtCl2(RCN)2] (R=Et (NC1), tBu (NC2), Ph (NC3), p-BrC6H4 (NC4)) and cis-[PtCl2(RCN)2] (R=Et (NC5), tBu (NC6), Ph (NC7)) react with 1 equiv of the hydroxyguanidine OC4H8NC(=NOH)NH2 (HG) furnishing the mono-addition products trans- and cis-[PtCl2(RCN){NH=C(R)ON= C(NH2)NC4H8O}] (1–4 and 9–11; 7 examples; 54–74% yield). Treatment of any of the nitrile complexes NC1–NC7 with HG in a 1:2 molar ratio generated the bis-addition products transand cis-[PtCl2{NH=C(R)ON=C(NH2)NC4H8O}2] (5–8 and 12–14; 7 examples; 69–89% yield). The PtII-mediated coupling between nitrile ligands and HG proceeds substantially faster than the corresponding reactions involving amid- and ketoximes and gives redox stable products under normal conditions. Complexes 1, 6·4CH2Cl2, 7·4CH2Cl2, 8·2CH2Cl2, and NC4 were studied by X-ray crystallography. Platinum(II) species 1–3, 10, 11, and especially 9, efficiently catalyze the hydrosilylation cross-linking of vinyl-terminated poly(dimethylsiloxane) and trimethylsilyl- terminated poly(dimethylsiloxane-co-ethylhydrosiloxane) giving high-quality thermally stable silicon resins with no structural defects. The usage of these platinum species as the catalysts does not require any inhibitors and, moreover, the complexes and their mixtures with vinyl- and trimethylsilylterminated polysiloxanes are shelf-stable in air.

dc.description.abstract

value:
cis- and trans-Isomers of the platinum(II) nitrile complexes [PtCl2(NCR)2] (R = NMe2,
N(C5H10), Ph, CH2Ph) were examined as catalysts for hydrosilylation cross-linking of vinyl-terminated
polydimethylsiloxane and trimethylsilyl-terminated poly(dimethylsiloxane-co-ethylhydrosiloxane)
producing high quality silicone rubbers. Among the tested platinum species the cis-complexes
are much more active catalysts than their trans-congeners and for all studied platinum complexes
cis-[PtCl2(NCCH2Ph)2] exhibits the best catalytic activity (room temperature, c = 1.0   10 4 mol/L,
 pot-life 60 min,  curing 6 h). Although cis-[PtCl2(NCCH2Ph)2] is less active than the widely used
Karstedt’s catalyst, its application for the cross-linking can be performed not only at room temperature
(c = 1.0   10 4 mol/L), but also, more efficiently, at 80  C (c = 1.0   10 4–1.0   10 5 mol/L) and
it prevents adherence of the formed silicone rubbers to equipment. The usage of the cis- and
trans-[PtCl2(NCR)2] complexes as the hydrosilylation catalysts do not require any inhibitors and,
moreover, the complexes and their mixtures with vinyl- and trimethylsilyl terminated polysiloxanes
are shelf-stable in air. Tested catalysts do not form colloid platinum particles after the cross-linking.

title: Stability Analysis of Linear Time-Delay Systems with Two Incommensurate Delays

dc.contributor.author

value: Zhabko, Alexey P.

dc.description.abstract

value: The contribution focuses on the stability analysis of linear time-delay systems within the framework of the Lyapunov – Krasovskii functionals. The method used is based on the idea to check positive definiteness of the functionals exclusively on the specific Razumikhin-type set of functions. For the systems with incommensurate delays, it is proposed to use the modified functionals depend on the Lyapunov delay matrix related to a nominal system with commensurate delays. The method is applied for the estimation of the stability domains in the parameter space.
