Quality of Work in Prostitution and Sex Work. Introduction to the Special Section
Full text linkIncreasingly, prostitution and other activities in the sex industries have been conceptualised as forms of labour, or at least as income-generating activities. As labour, these activities are exposed to particular risks with respect to health, working conditions, exploitation and stigmatisation. However, research on the actual conditions and circumstances existing in these markets, remains limited. The present article introduces some of the main issues researchers may face when studying quality of work in the sex industry, and it does so by introducing and discussing the six pieces of research published in the Special Section Exploitation and Its Opposite. Researching the quality of working life in the sex industries'. Four main points are discussed as being central to this emerging field of research: methodological challenges, the inclusion of different market segments, consideration of migration issues, and the role of legislative regimes. The authors stress the importance of developing precise comparisons between different types of sex work, of engaging between qualitative and quantitative approaches to quality of work, and finally of looking beyond the industry, comparing sex work to other forms of work

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
Adolescentes migrantes a contracorriente: tiempos de vida y escuela en el alumnado de Enseñanza Secundaria Obligatoria
Full text link[Resumo]
Esta tese de doutoramento analiza as experiencias escolares das adolescencias migrantes matriculadas en
Ensinanza Secundaria Obrigatoria, en clave de usos do tempo. Da canta de que a migración e a educación
vertébranse ao redor da familia, e de que os usos do tempo dos/as menores parten da individualidade, pero
teñen un alcance colectivo. Desde estes fundamentos, se plantexan dúas hipóteses: validar a existencia de
asimetría nos usos do tempo do alumnado migrante e non migrante, que pode derivar en desvantaxe
educativa; e validar a importancia que o fogar e o Estado teñen nesas experiencias escolares. Para proba lo,
establécense tres obxectivos: analizar os usos do tempo de vida dos/ as adolescentes, segundo a súa
procedencia (migrante ou non migrante); abordar a influencia que o fogar migrante exerce no uso do seu
tempo escolar; e, por último, estudar o impacto que a política educativa ten nas súas cotidianeidades. Cunha
metodoloxía mixta, aplicáronse dúas enquisas de diferente alcance e contexto, e realizáronse entrevistas en
profundidade a expertos/ as vinculados/ as coa institución educativa. Os resultados evidencian experiencias
de desvantaxe educativa no colectivo migrante que, fundamentalmente, explícanse pala súa condición de
migrante e clase subalterna.[Abstract]
This doctoral thesis analyses the school experiences of migrant adolescents enrolled in Compulsory Secondary
Education in Galicia in terms of time use. It explores the notion that migration and education are structured
around the family, and that although the seo pe is callective, minors' time uses are based on individuality. In
accordance with these principies, I considered two hypotheses: asymmetrical time uses of migrant and nonmigrant
pupils may lead to educational disadvantage; and the home and the State playa key role in shaping
these school experiences. In order to prove these hypotheses, I set three objectives: to analyse the life time
use of the adolescents in aceordanee with their (migrant or non-migrant) origins; to cansider the inlluenee 01
the migrant household on the use and distribution 01 their sehool time; and thirdly, to study the impaet 01
education poliey on their everyday lives. Using a mixed methodology, two surveys 01 eontrasting scape and
context were eondueted, and in-depth interviews were held with experts related to edueation. The results
reveal the edueational disadvantage 01 the migrant group, attributable mainly to their migrant status and
lower social class.[Resumen] Esta tesis doctoral analiza las experiencias escolares de las adolescencias migrantes matriculadas en Enseñanza

Variations 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
Colombianas en España y brasileiras en Portugal: un análisis interseccional de las migraciones de las mujeres en el espacio transnacional/poscolonial
Full text link[Resumen]
En el contexto de la expansión neoliberal y la feminización del proletariado global, desde una perspectiva interseccional y pos/decolonial, esta tesis doctoral explora veinte años de trayectorias migratorias/biográficas de mujeres brasileñas en Portugal y de mujeres colombianas en España. A partir de los testimonios de cuarenta migrantes, entrevistadas durante un trabajo de campo multi-situado, realizado en las periferias urbanas de São Paulo, Oporto, Madrid y Galicia, entre 2017 y 2019; se analiza el espacio transnacional como un continuum poscolonial que, al modo de una matriz, se articula por la intersección de múltiples relaciones dominación. Los resultados de la investigación apuntan a que las migraciones de mujeres colombianas y brasileiras a España y Portugal, constituyen una estrategia de supervivencia colectiva que es mediada por la colonialidad. La historia que vincula los territorios de origen y destino, proyecta representaciones etnosexuales de las mujeres que acaban por ser determinantes en la configuración de sus trayectorias migratorias/biográficas en el espacio transnacional/poscolonial. Las intersecciones del género, la raza en su doble dimensión, como nacionalidad y como raza imaginada, y la clase, ejecutan la incorporación de brasileiras y colombianas a los circuitos del trabajo globalizado a través de las políticas sexorraciales/migratorias de los Estados de acogida.[Resumo] No contexto da expansión neoliberal e a feminización do proletariado global, dende unha perspectiva interseccional e pos/decolonial, esta tese de doutoramento explora vinte anos de traxectorias migratorias/biográficas de mulleres brasileiras en Portugal e de colombianas en España. A partir das testemuñas de corenta migrantes, entrevistadas durante un traballo de campo multi-situado, realizado nas periferias urbanas de São Paulo, Porto, Madrid e Galicia, entre 2017 y 2019; analízase o espazo transnacional como un continuum poscolonial que, ao xeito dunha matriz, é artellado pola intersección de múltiples relacións de dominación. Os resultados da investigación apuntan a que, as migracións de mulleres colombianas e brasileiras a España e Portugal, constitúen unha estratexia de supervivencia colectiva, que é mediada pola colonialidade. A historia que vencella os territorios de orixe e destiño, proxecta representacións etnosexuais das mulleres que remetan sendo determinantes na configuración das súas traxectorias migratorias/biográficas no espazo transnacional/poscolonial. As interseccións do xénero, a raza na súa dobre dimensión, como nacionalidade e como raza imaxinada, e a clase, executan a incorporación de brasileiras e colombianas aos circuitos do traballo globalizado a través das políticas sexorraciais/migratorias dos Estados de acollida.[Abstract] In the context of neoliberal expansion and the feminisation of the global proletariat, from an intersectional and post-decolonial perspective, this doctoral thesis explores twenty years of migratory/biographical trajectories of Brazilian women in Portugal and Colombian women in Spain. Based on the testimonies of forty migrants, interviewed during a multi-sited fieldwork, carried out in the urban peripheries of São Paulo, Porto, Madrid and Galicia, between 2017 and 2019; I analyse the transnational space as a postcolonial continuum which, in the manner of a matrix, is articulated by the intersection of multiple relations of domination. The results of the research suggest that the migrations of Colombian and Brazilian women to Spain and Portugal constitute a collective survival strategy that is mediated by coloniality. The history that links the territories of origin and destination projects ethnosexual representations of women that end up being determinant in the configuration of their migratory/biographical trajectories in the transnational/postcolonial space. The intersections of gender, race in its double dimension, as nationality and as imagined race, and class, operate the incorporation of Brazilian and Colombian women into the circuits of globalised labour through the sex-racial/migratory policies of the host states
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
