Informetrics on M. N. Srinivas
No full textM. N. Srinivas, the well known sociologist is widely recognised as architect of modern Indian sociology and social anthropology. His publications have been analysed by year, domain, authorship pattern, channels of communication used. Keywords, etc. The results indicate that the papers published by him are of a nature that qualify him to be a 'role model' for the younger generations to emulate.
By the end of 1995, Srinivas had to his credit 144 papers which, included 33 broad papers in sociology and anthropology; 18 papers in social change; 28 papers in village studies; 12 papers on religion; 17 papers on caste and 36 papers of general popular interest. The periods 1958-61 and 1974-77, when Srinivas was 38-41 and 58-61 years old. were his most productive periods with highest publication activity

From the correspondence of M. P. Drahomanov: two unknown letters to M. V. Vodovozov of 1894
No full textThis publication introduces into scientific discourse little-known letters of prominent Ukrainian scholar, politician and publicist M. P. Drahomanov (1841-1895), discovered in the fond of V. I. Vernadsky in the Archive of the Russian Academy of Sciences in Moscow. Two letters written in the latest period of the life of M. P. Drahomanov, which are addressed to young economist and publicist Mykola Vasyliovych Vodovozov (1870-1896), expand the source base not only for M. P. Drahomanov’s biographers. They show his ties with Russian liberals, who later formed the core of the party of constitutional democrats. A preface to the publication contains a biography of M. V. Vodovozov, and the author makes a hypothesis on the history of an acquaintance of the correspondent and the addressee, which could be connected with M. V. Vodovozov’s brother, V. V. Vodovozov, and members of the “Shelter Fraternity”, and through them with M. P. Drahomanov. The analysis of the published letters proves that M. P. Drahomanov endeavored to widen through the “Shelter Fraternity” members his contacts with democratic circles in Russia, and also to find financial support for publishing letters of Bakunin and Struve
Coloring and covering problems on graphs
No full textThe \emph{separation dimension} of a graph , written , is the minimum number of linear orderings of such that every two nonincident edges are ``separated'' in some ordering, meaning that both endpoints of one edge appear before both endpoints of the other. We introduce the \emph{fractional separation dimension} , which is the minimum of such that some linear orderings (repetition allowed) separate every two nonincident edges at least times.
In contrast to separation dimension, we show fractional separation dimension is bounded: always , with equality if and only if contains . There is no stronger bound even for bipartite graphs, since . We also compute for cycles and some complete tripartite graphs. We show that when is a tree and present a sequence of trees on which the value tends to . We conjecture that when the -free -vertex graph maximizing is .
We also consider analogous problems for circular orderings, where pairs of nonincident edges are separated unless their endpoints alternate. Let be the number of circular orderings needed to separate all pairs, and let be the fractional version. Among our results: (1) if and only is outerplanar. (2) when is bipartite. (3) . (4) , with equality if and only if . (5) .
A \emph{star -coloring} is a proper -coloring where the union of any two color classes induces a star forest. While every planar graph is 4-colorable, not every planar graph is star 4-colorable. One method to produce a star 4-coloring is to partition the vertex set into a 2-independent set and a forest; such a partition is called an \emph{\Ifp}. We use discharging to prove that every graph with maximum average degree less than has an \Ifp, which is sharp and improves the result of Bu, Cranston, Montassier, Raspaud, and Wang (2009). As a corollary, we gain that every planar graph with girth at least 10 has a star 4-coloring.
A proper vertex coloring of a graph is \emph{-dynamic} if for each , at least colors appear in . We investigate -dynamic versions of coloring and list coloring. We prove that planar and toroidal graphs are 3-dynamically 10-choosable, and this bound is sharp for toroidal graphs.
Given a proper total -coloring of a graph , we define the \emph{sum value} of a vertex to be . The smallest integer such that has a proper total -coloring whose sum values form a proper coloring is the \emph{neighbor sum distinguishing total chromatic number} . Pil{\'s}niak and Wo{\'z}niak~(2013) conjectured that for any simple graph with maximum degree . We prove this bound to be asymptotically correct by showing that . The main idea of our argument relies on Przyby{\l}o's proof (2014) for neighbor sum distinguishing edge-coloring.Submission original under an indefinite embargo labeled 'Open Access'.

Effective Schools: Teacher Hiring, Assignment, Development, and Retention
No full textThe literature on effective schools emphasizes the importance of a quality teaching force in improving educational outcomes for students. In this paper, we use value-added methods to examine the relationship between a school’s effectiveness and the recruitment, assignment, development and retention of its teachers. We ask whether effective schools systematically recruit more effective teachers; whether they assign teachers to students more effectively; whether they do a better job of helping their teachers improve; whether they retain more effective teachers; or whether they do a combination of these processes. Our results reveal four key findings. First, we find that more effective schools are able to attract and hire more effective teachers from other schools when vacancies arise. Second, we find that more effective schools assign novice teachers to students in a more equitable fashion. Third, we find that teachers who work in schools that were more effective at raising achievement in a prior period improve more rapidly in a subsequent period than do those in less effective schools. Finally, we find that more effective schools are better able to retain higher-quality teachers, though they are not differentially able to remove ineffective teachers. The results point to the importance of personnel, and perhaps, school personnel practices, for improving student outcomes.
V. BRUSOV’S ARTICLE ON M. LOMONOSOV. INTRODUCTORY REMARKS BY IRINA ATAJANYAN (YEREVAN)
No full textThe author publishes V. Brusov’s paper «On Lomonosov». According to V. Brusov, M. Lomonosov is «the father of the Russian literature». Significantly, V. Brusov overlooked M. Lomonosov’s poetry, with a view towards his works on prosody. The publication’s author concludes that V. Brusov intended to write a research paper on M. Lomonosov’s life and creativity
The long-wavelength view of GG Tau A: rocks in the ring world
No full textWe present the first detection of GG Tau A at centimetre wavelengths, made with the Arcminute Microkelvin Imager Large Array at a frequency of 16 GHz (λ = 1.8 cm). The source is detected at >6 σrms with an integrated flux density of S16GHz = 249 ± 45 µJy. We use these new centimetre-wave data, in conjunction with additional measurements compiled from the literature, to investigate the long-wavelength tail of the dust emission from this unusual protoplanetary system. We use an MCMC-based method to determine maximum likelihood parameters for a simple parametric spectral model and consider the opacity and mass of the dust contributing to the microwave emission. We derive a dust mass of Md ~ 0.1 Msun, constrain the dimensions of the emitting region and find that the opacity index at λ > 7 mm is less than unity, implying a contribution to the dust population from grains exceeding ~4 cm in size. We suggest that this indicates coagulation within the GG Tau A system has proceeded to the point where dust grains have grown to the size of small rocks with dimensions of a few centimetres. Considering the relatively young age of the GG Tau association in combination with the low derived disc mass, we suggest that this system may provide a useful test case for rapid core accretion planet formation models
Why the inflation in legislation on women’s bodies
No full textThis dissertation argues that historical patriarchal theories have crept into the world’s legal systems to date, and as a result this has led to inflation in legislation upon women’s bodies. The author seeks to prove that patriarchal theories have become part of our social and legal institutions to date, resulting in unnecessary controls placed upon women’s bodies to the point that, women’s attempt to assert autonomy over their own bodies have been criminalised or placed under heavy civil penalties. The author suggests that this has been particularly so because, women have been relegated to the private sphere and as such, are underrepresented within the legislature, political arenas, the process passing legislation and the legal profession in general. As well as analysing the structure of the various social, legal and political institutions as they relate to the causes of inflation in legislation upon women’s bodies, the author investigates the medicalisation of women’s bodies which has led to over legislation with regards to: legislation and women’s attire, Indecent exposure and the breast, the treatment of military women with regards to their bodily autonomy and pregnancy
Perfect Competition
No full textIn his 1987 entry on ‘Perfect Competition’ in The New Palgrave, the author reviewed the question of the perfectness of perfect competition, and gave four alternative formalisations rooted in the so-called Arrow-Debreu-Mckenzie model. That entry is now updated for the second edition to include work done on the subject during the last twenty years. A fresh assessment of this literature is offered, one that emphasises the independence assumption whereby individual agents are not related except through the price system. And it highlights a ‘linguistic turn’ whereby Hayek’s two fundamental papers on ‘division of knowledge’ are seen to have devastating consequences for this research programme.Allocation of Resources; Perfect Competition; Exchange Economy
