Communication's quest for whiteness: the racial politics of disciplinary legitimacy

ABSTRACT

This essay examines communication's historical anxieties regarding disciplinary legitimacy as an investment in whiteness. We argue that such anxieties are predicated upon a normative ideal of citizenship. As such, rhetorics of disciplinary legitimacy enact white civil society's originary exclusion, which is antiblackness. To illuminate the ways antiblackness finds expression in these anxieties, we engage the field's lengthy archive of public musings regarding legitimacy to trace the rhetorical workings of antiblackness therein.     

STRUCTURE OF PRIMARY MATHEMATICS TEACHER EDUCATION PROGRAMS IN SPAIN

Spain was 1 of the 17 countries that participated in the International Association for the Evaluation of Educational Achievement’s Teacher Education and Development Study in Mathematics (TEDS-M 2008). In this paper, we explore and describe the structure of Spanish primary mathematics teacher education programs. We analyzed the documents collected from the 48 sampled Spanish institutions that participated in TEDS-M. Our approach to the syllabus analysis focused on the established content dimension of curriculum in educators’ syllabi. These contents are structured into 4 knowledge domains—school mathematics, advanced mathematics, general pedagogy, and mathematics pedagogy—and categorized into subjects and topics. The results show that Spanish teacher education programs are diverse across institutions, but follow a basic structure that emphasizes the teaching of general pedagogy subjects.     

Analyzing the Spell of War: A War/Peace Framing Analysis of the 2009 Visual Coverage of the Sri Lankan Civil War in Western Newswires

The goal of this study was to analyze the extent to which the visual coverage of the final stages (April/May 2009) of the long-lasting Sri Lankan Civil War relied on war and peace frames. Based on the revolutionary conceptual work of Norwegian scholar Johan Galtung, who viewed war and peace journalism as two competing frames in covering conflicts and wars, we examined news photographs available from Associated Press (AP), Reuters, and Getty/Agence France-Press (AFP). To date, this topic has been discussed from mostly normative viewpoints, and only little research combined the peace journalism concept with visual framing and/or the role of newswires as gatekeeper of information. We tested this concept empirically by using content analysis of editorial news photographs of the conflict in the three leading Western newswires. By and large, our results suggest that overall visual coverage of the conflict waxed and waned over time, but was primarily driven by visuals originated in the Sinhalese-dominated regions of Sri Lanka. Further, newswires are serving very different purposes and news markets: the AP–and to a lesser extent also Getty/AFP–with their focus on external events (therefore qualifying for peace journalism) and Reuters with a stronger focus on the conflict itself (thus qualifying for war journalism). Overall, the stock photo agency Getty/AFP was found to be the newswire that is most likely to provide media outlets with photographs highlighting peace frames, with the most balanced coverage between the two conflict parties and a particular emphasis on peace demonstrations worldwide, negotiations and summit meetings.     

Ecotoxicity assessment using ciliate cells in millifluidic droplets

Precise analysis of the aquatic cells and their responses to the toxic chemicals, i.e., water disinfective agents, is of crucial importance due to their role in the ecosystem. We demonstrate the application of the droplets based millifluidic tool for isolating and longtime monitoring of single Paramecium tetraurelia cells using a large number of water-in-oil emulsion droplets. Due to the automated monitoring of the fluorescence signal, the droplets containing cells are distinguished from the empty reservoirs. A viability indicator is used to follow the metabolic dynamic of the cells in every single droplet. Finally, we perform ecotoxicity tests in droplets, exposing the encapsulated paramecia cells to silver nitrate for determination of EC50 levels, and compare the output with the conventional microtiter plate assay.     

History of Spanish Mathematics Education Focusing on PhD Theses

This article offers an overview of mathematics education in Spain, analyzing the production of PhD theses over the last 30 years. This period has been divided into four cycles that describe the evolution of Spanish research in the field of mathematics education, together with changes in university and social politics. This paper also includes a forecast of the number of theses that will be produced over the next 7 years, thus predicting the future progress and development of this area of research.
