This document provides an overview of a study analyzing newspaper articles about nanotechnology from three Spanish newspapers over 13 years using qualitative data analysis software. The study aims to understand how nanotechnology has been portrayed in the Spanish press and how risk discourse has been framed. Researchers analyzed over 600 articles totaling 392,666 words using Atlas.ti software to identify themes, topic clusters, and changes over time. Preliminary results found longitudinal shifts in key themes and differences in risk discourse framing between newspapers. The researchers concluded that quantitative text analysis helps provide an overview while qualitative coding aids interpretation.

- 4. Theoretical Background Social Representations Theory (Moscovici, 1988). Focus on the use metaphors and clusters of meanings to determine the core of representations present in the mass media. Researchers in this area are focused on the idea that in the public sphere there are competing definitions, in what is a complex game played for control of semantics in the public sphere (Gaskell et al., 1998). Anchoring and Objectification (Moscovici, 1988) Similarly, there is the notion of “mediascapes” (Van Loon, 2002), the symbolic environment in which a technology is debated.

- 6. Current research Studies on nanotechnology and the mass media have increased in the past few years due to the increasing hype that is surrounding this scientific domain. Research on nanotechnology’s mediascapes have focused initially on UK and US, but now other countries are under scrutiny (see Kjølberg, 2009; Kjærgaard, 2010) . In Spain, to our knowledge, nothing similar exists at the moment. In addition, most studies focused mainly on risk/benefits analytical frame within the media analysis.

- 8. Methodological notes 646 articles (1997 to 2010) from three main spanish newspapers: El Mundo – 432,204 daily copies on average, (moderate) El Pais – 330,634 daily copies on average, (left-leaning) ABC – 240,225 daily copies on average, (right-leaning) 392.666 words, 32.477 lemmas From Lexis - Nexis database (www.lexisnexis.com) Sampling criteria: presence several keywords such as ‘nanotecnologia’, ‘nanosciencia’, ‘nanoparticulas’, ‘nanostructura’ and ‘manipulación atómica’, ‘ingeniería atómica’.
- 10. Analysis T-Lab 7 – atlas.ti 6.1 Articles were pre-processed by human coding: tagging and establishing main variables (newspaper, year, etc.) We explored his texts using different kinds of tools: Co-occurrence analysis and automatic thematic analysis Comparative analysis Automatic thematic analysis of EC as mean to unravel core packets of meanings in the coverage of nanotechnology in Spanish Press. Cluster analysis of themes and their longitudinal evolution Headline were analyzed to find main categories Three main codes have been applied to identify the attitude of newspapers

Overview of the overall coverage Overview of a given newspaper coverage Not limited to the risk/benefit analytical frame Complementary to qualitative coding or a reliability tool to compare human thematic coding and automatic one Qualitative analysis helps in giving sense to the information Problem of the attitude Risk of hyper analysis 16
