Migration to the United States, remittances and regional development [Migraci�n a Estados Unidos, remesas y desarrollo regional]
No full textAn approach that considers migration as a component of the socio-economic functionality of human settlements is proposed in this essay as it is established by scholars working on regional analysis, in particular Alonso's theory of movement (1978, 1980); the works by Isard (1979, 1985), Isard and Anselin (1979), Greenwood (1985), Nijkamp and Poot (1986) and Cushing and Poot (2003). To support this proposal, the autors analyze remittances from the United States in its geographical context. Furthermore, the situation of migration and remittances on regional development using said approach is studied. To illustrate the importance that the regional analysis and geographical dimensions have on determining factors of migration, an example of general geographical distribution of remittances by states and municipalities in Mexico is used, as well as their impacts on their production

New long-term tendencies of emigration of mexican people toward the united states and their remittances [Nuevas tendencias de largo plazo de la emigraci�n de mexicanos a estados Unidos y sus remesas]
No full textThis article show evidence of a deep change in Mexican emigration to the U.S., both as for the number and profile of people who emigrate and the remittances they send their relatives in Mexico. In the last three decades of the last century and the first lustrum of the current one, both variables experienced uninterrupted growth rates; however, there are quantitative and qualitative reasons that allow state we are before the beginning of a new tendency to their stabilization in the long term. This change fundamentally responds to the hardening of the U.S. migratory policy as a response to September 11 attacks, as well as the deep structural crisis in this country, which appears in the loss of international competitiveness and in the necessary industrial reconversion towards sectors less intense in labor force

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
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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
