  • Abstract

    The SIARD-database contains variables from a manual content analysis on food safety for which three different types of documents were analysed: 1. texts from websites, 2. articles from print media and 3. documents on the political agenda (plenary debates and documents from relevant committees). The variables can be located at two different levels - at the document level and at the speaker/statement level. A maximum of three different speakers/statements could be coded for website texts and print media articles, and any number of speakers/statements for political agenda documents. The coding at the document level consists of metadata (e.g. date of publication, centrality of the food safety topic in the article), information on the initiation of the documents (events) and references within the documents to (other) media. The coding at the level of speakers/statements consists of individual elements of frames. These are variables for the more precise specification of the addressed problem within the topic of food safety, as well as the naming of reasons / consequences / proposed solutions. Topics: type of the document; month of crawl/ publication; country; name of newspaper; title (headline offline documents); URL of the page; domain the page belongs to; organisation the domain of the page belongs to; social group and country of the actor that issues the page; date of publication; type of article; type of the political document; type of plenary document; initiator of business in political document; real-world event, that stimulated the writing of the document; centrality of the issue; reference to other online or offline media; rank of the most important actor; surname and name of the actor; name of the organisation the actor belongs to; additional information on the function of the actor; social group of the actor; organisational extension of the organisation or institution the actor belongs to; country of the actor/ organisation the actor belongs to; party affiliation of the actor; addressee addressed by the author; social group of the addressee; scope of the addressee; country of the addressee; party affiliation of the addressee; problem definition of the food problem; type of food in question; evaluation of the food problem by the author; specific perspective the actor takes on the food problem; cause of the problem; effect (consequences); treatment. A data set in SPSS- and Stata format is available under study number ZA6794.
Temporal Coverage
  • 2012-06-01 / 2013-05-31
    Publication data of online documents are partly outside the survey period, i.e. they were published before the start of the survey period; however, these documents were accessible on the respective websites during the survey period.
Geographic Coverage
  • Germany (DE)
  • Switzerland (CH)
  • United Kingdom (GB)
  • United States (US)
  • European Union
Probability: Simple random; Total universe/Complete enumeration; Sampling Procedure Comment: The selection of texts was initially limited to documents containing a keyword or combination of keywords related to food safety. The following search string was used: (Lebensmittelsicherheit ODER ((Lebensmittel / Nahrung / Futter) UND (Erreger / Keim / Epidemie / Seuche / Krankheit / Gesundheits / Infiziert / Verunreinig / Kontamin / Belast / Gentechni / gefähr / Gefahr / Skandal / Hygien / Risiko / EFSA / BVL / BAG))) respectively (Food safety OR ((food / aliment / feed) AND (germ / epidemic / scare / illness / health / infected / borne / contagious / contaminated / polluted / GM food / genetical / hazard / bioengineer / harmful / scandal / hygiene / risk / EFSA / FDA / FSA))). The search string in the language of the country under investigation was used for both print media articles and political documents, while both search strings were used in parallel for online documents and political documents at EU level. 1) For the online documents, a random sample of 35 texts per month and country was drawn, whereby the selection of the URL/website on which a document was searched for was influenced by the network measure Indegree and thus weighted (Probability Proportional to Indegree-Sampling cf. Maier et al., 2014). URLs/websites within the web presences of organisations that were frequently linked to in the network thus had a greater probability of being considered for sampling. 2) A simple random sample of 35 articles per month and country was taken for the print media articles. 3) For the political agenda a total universe/complete enumeration was conducted.
