European policies for social inclusion of Roma : Catch 22?
No full textThe article analyzes contemporary political discourses with regard to social inclusion of Roma on the basis of comparison with achievements and failures in the previous historical period of the communist rule in Eastern Europe. It argues that since the vast majority of the European Roma had lived in the past and continue living nowadays in the countries of Eastern Europe, no successful policy for their inclusion is possible without taking into account the experiences and outcomes of the actions for Roma integration in the socialist period. The experience from the times of socialism shows that successful policies are possible only in an appropriate socio-political context and only if accomplished within the mainstream approach. Against this background, the article scrutinizes the European Policies for Social Inclusion of Roma, and explains why they present a Catch 22 situation: There is a vicious cycle of problems which need to be solved; the solution requires a special policy for inclusion, however this policy stigmatizes Roma and sets them even more apart from the rest of society. Thus the vicious cycle of problems expands. The main point of the article is to propose an explanation of this failure of democracy and liberalism, which could constitute a useful lesson for the future.Peer reviewe
Leptosaldinea cobbeni Popov & Heiss, 2016, sp.nov.
No full textLeptosaldinea cobbeni sp.nov. (Figs. 1–12) Type material. Holotype: macropterous female preserved in a piece of Burmese amber which is embedded in a block of transparent artificial resin for better conservation, provided with following red label: “ Holotype / Leptosaldinea gen.nov. / cobbeni sp. nov. / des. Heiss & Popov, 2015 ”. The holotype is deposited in the collection of the second author (EH) at the Tiroler Landesmuseum, Innsbruck, Austria. Body convex; left eye and pronotal margin damaged, surface of median part of pronotum, scutellum and clavus missing and probably eaten by scavengers, their remains depressed and not clearly discernible; legs and antennae complete with long spines and setae. Description. As given in the generic diagnosis and description. Measurements (mm). Length 2.75; width of hemelytra 1.35; length of antennae 1.95, ratio length of antennae / width of head = 2.78; length of antennal segments I:II:III:IV = 0.15: 0.25: 0.75: 0.80; length of rostral segments I:II:III:IV =?: 0.15: 0.20: 0.20; length of pronotum at middle 0.4, anterior width 0.5, posterior width 0.85; scutellum length 0.37; legs: femur:tibia:tarsus including claws: fore leg 0.875: 0.8: 0.4; middle leg 0.875: 0.875: 0.375; hind leg 1.0: 1.40: 0.5. Drawings might show slight differences to given measurements because of partly obscured visibility of structures. Etymology. Named after the eminent Dutch hemipterologist René Cobben, who proposed the subfamily Leptosaldinae for the first discovered leptosaldine species, Leptosalda chiapensis.Published as part of Popov, Yuri A. & Heiss, Ernst, 2016, A remarkable fossil leptosaldine bug from Mid-Cretaceous Burmese amber (Hemiptera: Heteroptera: Leptopodomorpha: Leptopodidae), pp. 233-238 in Zootaxa 4137 (2) on page 237, DOI: 10.11646/zootaxa.4137.2.5, http://zenodo.org/record/25743
The minimum k-cover problem
No full textWe consider the problem of determining the minimum cardinality collection of substrings, each of given length k ≥ 2, that "cover" a given string x of length n. We describe an approach to solve this problem. This approach is based on constructing an explicit reduction from the problem to the satisfiability problem. © 2013 Anna Gorbenko and Vladimir Popov
Computing Popov Forms of Polynomial Matrices
No full textThis thesis gives a deterministic algorithm to transform a row reduced matrix to canon-
ical Popov form. Given as input a row reduced matrix R over K[x], K a field, our algorithm
computes the Popov form in about the same time as required to multiply together over
K[x] two matrices of the same dimension and degree as R. Randomization can be used to
extend the algorithm for rectangular input matrices of full row rank. Thus we give a Las
Vegas algorithm that computes the Popov decomposition of matrices of full row rank. We also show that the problem of transforming a row reduced matrix to Popov form is at least
as hard as polynomial matrix multiplication
Perturbative Yang–Mills theory without Faddeev–Popov ghost fields
No full textA modified Faddeev–Popov path integral density for the quantization of Yang–Mills theory in the Feynman gauge is discussed, where contributions of the Faddeev–Popov ghost fields are replaced by multi-point gauge field interactions. An explicit calculation to O(g2) shows the equivalence of the usual Faddeev–Popov scheme and its modified version.© 2018 The Author
Grimaldinia pronotalis Popov & Heiss, 2014, sp. n.
No full textGrimaldinia pronotalis sp. n. (Figs. 1–2, photo 1–2) Holotype. Submacropterous specimen, sex not determined, in a half-moon shaped piece of Burmese Amber (20 x 4 x 7mm) embedded in a block of transparent resin; left forewing damaged by an oval cut out probably caused by scavengers; specimen is ventrally attached to a strip of lizard skin, thus ventral side of specimen is not visible, lateral view partly obscured by amber impurities; membraneous hind wing of the left forewing is laterally roundly exposed and overlapping the right fore wing, its surface showing dense microsculpture and longitudinal venation. Deposited as BUB-LEP- 1 in the collection of the second author. Description. As given in the generic diagnosis and description. Coloration of dorsal and ventral side (as far as visible) uniformly black. Measurements. Length 3.0mm; head width / length 45 / 24, anterior width between eyes 6; pronotum length at middle / width 11 / 27, length laterally 14; scutellum length / width 33 / 33; length of eye 10, diameter 4. Etymology. Refers to the conspicuous configuration of the pronotum.Published as part of Popov, Yuri A. & Heiss, Ernst, 2014, Grimaldinia pronotalis n. gen., n. sp. from Mid-Cretaceous Burmese Amber (Hemiptera: Heteroptera, Leptopodidae, Leptosaldinae), pp. 444-450 in Zootaxa 3878 (5) on page 449, DOI: 10.11646/zootaxa.3878.5.2, http://zenodo.org/record/22909
The Long Road to Normalcy
No full textThe goal of this study is to reveal the long-term trajectory of Russian economic development and to make predictions for the future. The study starts with a much discussed question: why Russia did worse economically during transition than most other countries in Europe and Asia? It is argued that it was partly caused by objective circumstances before transition (distortions in industrial structure and in trade patterns accumulated during the era of central planning), but mostly by the weakening of the institutional capacity of the state during transition.Economic transition, institutional trajectories, Russia, China
Some exact solutions of the semilocal Popov equations
No full textAbstractWe study the semilocal version of Popov's vortex equations on S2. Though they are not integrable, we construct two families of exact solutions which are expressed in terms of rational functions on S2. One family is a trivial embedding of Liouville-type solutions of the Popov equations obtained by Manton, where the vortex number is an even integer. The other family of solutions is constructed through a field redefinition which relates the semilocal Popov equation to the original Popov equation but with the ratio of radii 3/2, which is not integrable. These solutions have vortex number N=3n−2 where n is a positive integer, and hence N=1 solutions belong to this family. In particular, we show that the N=1 solution with reflection symmetry is the well-known CP1 lump configuration with unit size where the scalars lie on S3 with radius 3/2. It generates the uniform magnetic field of a Dirac monopole with unit magnetic charge on S2
Development theories and development experience: half a century journey
No full textThis paper examines the impact that development theories have had on development policies, and the inverse impact of actual successes and failures in the global South on development thinking. It is argued that development thinking is at the cross-roads. Development theories in postwar period went through a full circle – from Big Push and ISI to neo-liberal Washington consensus to the understanding that neither the former, nor the later really works in engineering successful catch-up development. Meanwhile, economic miracles were manufactured in East Asia without much reliance on development thinking and theoretical background – just by experimentation of the strong hand politicians.
