Introduction
Full text linkThe goal of this volume is precisely to explore the intersections between Cultural Studies and Migration Studies, opening more cracks and proposing new ideas, themes, and approaches that speak to the varied field of migration studies, starting from the approach of cultural studies and post-colonial studies. By doing so, we will contribute to opening up visibilities and trajectories invisible in other discourses and narratives. The contributions collected here assume, in fact, different points of view not only concerning the disciplines involved and the methodologies adopted but also the addressed spatial and temporal contexts that have much to offer
Narrating Palestinian Lives Through Phototexts. The Case of Edward W. Said
No full textStarting with the intersection between literature and visual culture, this chapter addresses the representation of the Palestinian people’s cultural identity through a specific genre in-between literature and photography: the phototext. In what follows After the Last Sky. Palestinian Lives, by Edward W. Said and Jean Mohr (1986), will be analyzed as a case study that still has an impact on the critical discourse around cultural identity. Through the phototextual representation, Said and Mohr demonstrate the way in which dispossessions, resettlements and exile impact on the everyday life and the cultural identity of people. More importantly, this endeavor will also focus on the necessity for Palestinians of telling their own story, and of making that story heard. All these issues involve, though in different and specific ways, not only Palestinian lives, but those of all people suffering from the same processes
Humanitarian Orientalism and Photography of Migrant Women
No full textAware of the limitations of Edward Said’s Orientalism theorised
almost half a century ago, this chapter strived to analyse some of
the late 19th and early 20th century photographic representations
of the women of North Africa and to compare them with the
contemporary photographs taken of women in the Middle East.
This comparison between the images of the female inhabitants of
the Saidian ‘Orient’ aimed at highlighting the visual articulations
of information and control
Ascorbic Acid determination using linear sweep voltammetry on flexible electrode modified with gold nanoparticles and reduced graphene oxide
No full textIndium tin oxide (ITO) coated on flexible polyethylene terephthalate (PET) substrate electrode was modified with reduced graphene oxide and gold nanoparticles by simple co-electrodeposition performed at -0.8 V vs SCE for 200 s. All samples were characterized by electron scan microscopy. The as prepared electrode was used as electrochemical sensor to selective detection of ascorbic acid using linear sweep voltammetry. Excellent results were obtained in a linear range from 20 to 150 μM of ascorbic acid with a limit of detection of about 3.1 μM (S/N=3.3). The sensors have a reproducibility of about 5.5% and also show high selectivity towards different interferents such as chlorine, calcium, magnesium, sulphate ions, sodium and glucose. Ascorbic acid was detected also in milk samples demonstrating the possibility quantify this analyte in real samples with a very cheap method
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
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
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
