The Ukrainian Women’s Movement in Emigration (1945-1951) Domesticity, Nationalism, and Feminism in Displaced Person Camps
No full textThrough the analysis of memoirs, newspaper articles, and oral history interviews, this article explores the organizational efforts of Ukrainian women who found themselves in displaced person camps in postwar Europe. While they praised elements of domesticity and reiterated essentialized gendered roles of raising children and keeping houses, women nevertheless claimed an active involvement in political struggles, challenging the public-private distinction that relegates them to the domestic sphere. This case study enables the understanding of how discourses and institutions, both patriarchal and feminist, circulate in transnational milieus of nation-building, critically addressing the gendered logic through which the language of nationhood, belonging, and migration is not only constructed but also contested
CBMOM - An highly scalable MoM approach for electrically large multiscale EM radiation and scattering problems
Full text linkIn this paper, we describe a new and efficient strategy for solving linear system of equations arising in the application of Method of Moments to electromagnetic problems. This new approach is based on the use of Characteristic Basis Functions (CBFs) that are defined on macro domains (blocks), and include a relatively large number of conventional subdomains functions, defined on triangular or rectangular patches. The use CBFs leads to a significant reduction in the number of unknowns, and, as a result, the technique enables us to use a direct solver, as opposed to iteration. Numerical results are presented to demonstrate the accuracy and efficiency of the CBFM when used to solve several test problems
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Analysis of Large Aperture Antenna Arrays Using A Hybrid Mode Matching/Characteristic Basis Functions Method
No full textVariations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Generation of Characteristic Basis Functions by using Sparse MoM Impedance Matrix to Construct the Solution of Large Scattering and Radiation Problems
Full text linkSeveral approaches to circumventing the problem of excessive memory and computing time associated with large method-of-moments (MoM) impedance matrices have been explored. Most of these approaches rely on iteration methods to solve large problems, and this can lead to convergence difficulties when dealing objects with multi-scale features. In contrast, the CBMOM technique significantly differs from the above approaches in several aspects. Most importantly, CBMoM uses a new type of high-level basis function, called the characteristic basis functions (CBF), which are used to represent the unknown induced current. The computation of the CBFs allows the iteration methods to be bypassed altogether. The computation of the CBFs represents the most time-consuming and memory demanding task in the CBMoM. To obviate these limitations, a new approach for generation of the CBF matrix equation is proposed in this paper. It utilizes a sparsified MoM impedance matrix, whose use not only simplifies the calculation of the CBFs, but reduces the storage requirement and computational time as well. Numerical results are presented below to validate the proposed metho
Il progetto del monumento-memoriale
No full textLa tomba monumento di Rocco Scotellaro, opera dei BBPR, rappresenta un esempio notevole di monumento commemorativo architettonico.
Nel 1957 Ernesto N. Rogers viene incaricato da Carlo Levi per la realizzazione della tomba del poeta e sindacalista delle lotte contadine morto giovanissimo. Scrivono infatti gli architetti nella relazione di progetto: “Situata nel cimitero di Tricarico, il paese natale di Rocco Scotellaro, questa tomba vuole rendere omaggio allo spirito del poeta e dell’uomo di azione”.
Il tema di questo monumento è, in definitiva, una finestra aperta in un muro di pietra sul limite del cimitero, che si affaccia verso il paesaggio del Basento. Si contrappongono, così, la tomba, simbolo di morte, e il vano aperto dalla finestra, simbolo di speranza
