Statistical modeling for biological systems: in memory of andrei yakovlev
No full textThis book commemorates the scientific contributions of distinguished statistician, Andrei Yakovlev. It reflects upon Dr. Yakovlev’s many research interests including stochastic modeling and the analysis of micro-array data and throughout the book it emphasizes applications of the theory in biology, medicine and public health. The contributions to this volume are divided into two parts. Part A consists of original research articles, which can be roughly grouped into four thematic areas, (i) branching processes, especially as models for cell kinetics, (ii) multiple testing issues as they arise in the analysis of biologic data, (iii) applications of mathematical models and of new inferential techniques in epidemiology, and (iv) contributions to statistical methodology, with an emphasis on the modeling and analysis of survival time data. Part B consists of methodological research reported as a short communication, ending with some personal reflections on research fields associated with Andrei and on his approach to science. The Appendix contains an abbreviated vitae and a list of Andrei’s publications, complete as far as we know. The contributions in this book are written by Dr. Yakovlev’s collaborators and notable statisticians including former Presidents of the Institute of Mathematical Statistics and of the Statistics Section of the AAAS. Dr. Yakovlev’s research appeared in four books and almost 200 scientific papers, in mathematics, statistics, biomathematics and biology journals. Ultimately this book offers a tribute to Dr. Yakovlev’s work and recognizes the legacy of his contributions in the biostatistics community
State-business relations in Russia in the 2000s: From the capture model to a variety of exchange models?
Get PDFUsing data from a 2009 survey of 957 manufacturing enterprises, this paper examines relations between the state and business as well as priority differences in the distribution of governmental support by federal, regional and local authorities. Regression analysis reveals that a “model of exchange” is the predominant pattern as opposed to “state capture” (in the case of big firms) or “grabbing hand” (in the case of SMEs), both of which were typical of the 1990s. However, there are some differences in priorities at different levels of government. The federal government in 2007-2008 provided more support to state-owned and mixed enterprises providing stable employment, while regional authorities more often supported firms that were pursuing modernization. These trends could pave the way for a shift in governmental policy at the regional level from ”state capture”/”grabbing hand” to the Chinese-style “helping hand” model.state capture; state-business relations; Russia
The Russian Economy at the Crossroads : Before and Beyond the Ukrainian Crisis. Interview with Andrei Yakovlev
No full textInterview article with Andrei Yakovlev, professor at the Higher School of Economics in Moscow and head of the Institute for Industrial and Market Studies on recent tendecies. Yakovlev, a leading Russian economist, has a deepknowledge of the transformation of Russian enterprise throughout the post-Soviet time. In this interview, he puts the microeconomic perspective within a broad political economic context and evaluates the policy choices made by Russia’s political elites after the Arab Spring in 2011. Although he is quite pessimistic about Russia’s prospects, Yakovlev suggests that the new geopolitical situation and sanctions have created promising opportunities for the Russian economy. However, these opportunities can be used only if Russian elites achieve a new consensus regarding redistribution of economic rent

A C++ Program for the Cramér-Von Mises Two-Sample Test
Get PDFAs larger sets of high-throughput data in genomics and proteomics become more readily available, there is a growing need for fast algorithms designed to compute exact p values of distribution-free statistical tests. We present a program for computing the exact distribution of the two-sample Cramér-von Mises test statistic under the null hypothesis that the two samples are drawn from the same continuous distribution. The program makes it possible to handle substantially larger sample sizes than earlier proposed computational tools. The C++ source code for the program is published with this paper, and an R package is under development.
Ownership structure and development of Polish life insurance companies - evidence from 1991 to 2004
No full textThe main aim of this paper is to demonstrate the relationship between changes in the ownership structure and the development of life insurance companies in Poland. The simple regression model is used to reveal the relation. The findings of this study, that the solvency ratio, overall indebtedness ratio, premiums retention ratio and profitability ratio on technical activity and sales are positively related with the changes in the share of foreign capital and especially that the claims ratio is negatively related, suggest that foreign investments have greatly influenced the development of the life insurance industry in Poland during the transition period
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Between vision and reality: promoting innovation through technoparks in Kazakhstan
No full textA common motivation for the technopark movement is the belief that technoparks promote innovation and economic growth at regional and/or national levels. The paper analyses the role of technoparks as instruments of innovation promotion in Kazakhstan using data from a firm survey and interviews. Our results suggest that, unlike what is assumed in the innovation policy literature, technoparks do not house firms dealing with the commercialisation of innovations that are ready for introduction to the market. Technopark firms are no more innovative than other firms. They are oriented largely towards the local market, and operate in traditional sectors; the frequency and intensity of their external links are more developed than are their internal links. The key motivations for relocating to a technopark seem to be lower rents and the possibility of accessing finance. Overall, Kazakh technoparks seem to be successful in terms of facilitating business incubation, but much les so in terms of innovation promotion and diversification of the economy. Currently, Kazakh industry does not make any demands for local R&D, and its sources of competitiveness lie in non-R&D activities. This suggests that innovation policy should focus on assisting companies to upgrade their technological capabilities to the level that they can articulate their R&D demands. Focusing on technoparks as the main mechanism to improve competitiveness and diversify the economy is an ineffective and uncertain a policy option at this stage of the country's economic development. However, there seems to be significant scope for supporting business incubation. These conclusions are of relevance to other emerging economies
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
