Baile de máscaras. Mulheres judias e prostituição. As polacas e suas associações de ajuda mútua de Beatriz Kushnir
No full textOriginalmente apresentado como dissertação de Mestrado no Programa de Pós-Graduação em História da Universidade Federal Fluminense, em novembro de 1994, o livro de Beatriz Kushnir, Baile de Máscaras: Mulheres Judias e Prostituição: As Polacas e suas Associações de Ajuda Mútua, publicado pela Editora Imago em 1996, representa sem dúvida uma contribuição significativa não apenas no âmbito mais geral da história das mulheres e das relações de gênero, mas também, mais especificamente, para os estudossobre movimentos imigratórios de grupos de origem judaica para as Américas – em particular para o Brasil –, bem como para as reflexões sobre a questão da prostituição na sociedade brasileira

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Development of creative abilities of younger schoolchildren in conditions of institutions of additional education
No full textThe process of rapid development of the creative activity of schoolchildren requires a responsible attitude of the education system, to pedagogical conditions that should contribute to the development of the creative abilities of children.
In this article the problems of development of creative abilities of younger schoolchildren are considered. The characteristic features of the influence of institutions of additional education on the development of creative abilities of children are analyzed. It is shown that institutions of additional education play a huge role in society. The author reveals the tasks, forms and types of activity of institutions of additional education. The necessity of creating certain conditions for the education of younger schoolchildren for the development and introduction of children into creative activity has been identified and justified. The article presents methods and results of diagnosing the level of creativity of younger schoolchildren. On the basis of the study, pedagogical recommendations are highlighted that help to create conditions for the development of the creative abilities of younger schoolchildren
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Optimal Multi-Dimensional Auctions: Conjectures and Simulations
No full textWe explore the properties of optimal multi-dimensional auctions in a model
where a single object of multiple qualities is sold to several buyers. Using
simulations, we test some hypotheses conjectured by Belloni et al. [3] and
Kushnir and Shourideh [7]. As part of this work, we provide the first
open-source library for multi-dimensional auction simulations written in
Python.Comment: 10 pages, 4 figure
Improved Range Searching And Range Emptiness Under FHE Using Copy-And-Recurse
No full textRange counting is the problem of preprocessing a set of points, such that given a query range we can efficiently compute . In the more general range searching problem the goal is to compute , for some function .
It was already shown (Kushnir et al. PETS\u2724) how to efficiently answer a range searching query under FHE using a technique they called Copy-and-Recurse to traverse partition trees.
In the Range emptiness problem the goal is to compute only whether . This was shown (in plaintext) to be done more efficiently.
Range emptiness is interesting on its own and also used as a building block in other algorithms.
In this paper we improve and extend the results of Kushnir et al.
First, for range searching we reduce the overhead term to the optimal , so for example if the ranges are halfspaces in bounded by hyperplanes then range searching can be done with a circuit of size , where is the size of the sub-circuit that checks whether a point lies under a hyperplane.
Second, we introduce a variation of copy-and-recurse that we call leveled copy-and-recurse. With this variation we improve range searching in the 1-dimensional case as well as traversal of other trees (e.g., binary trees and B-trees).
Third, we show how to answer range emptiness queries under FHE more efficiently than range counting.
We implemented our algorithms and show that our techniques for range emptiness yield a solution that is faster than the previous results for a database of points
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
