Populism as political communication style An empirical study of political parties' discourse in Belgium

Abstract: The scientific debate about populism has been revitalised by the recent rise of extreme-right parties in Western Europe. Within the broad discussion about populism and its relationship with extreme-right, in this article, we confine ourselves to three topics, a conceptual, an epistemological and an empirical issue. First, taking a clear position in the ongoing definition struggle, we define populism primarily as a specific political communication style. We conceive of populism as a political style essentially displaying proximity of the people, while at the same time taking an anti-establishment stance and stressing the (ideal) homogeneity of the people by excluding specific population segments. Second, we point out that defining populism as a style enables us to turn it into a useful concept that has too often remained vague and blurred. Third, drawing on our operational definition of populism, a comparative discourse analysis of the political party broadcasts of the Belgian parties is carried out. Our quantitative analysis leads to a clear conclusion. In terms of the degree and the kinds of populism embraced by the six political parties under scrutiny, the extreme-right party Vlaams Blok behaves very differently from the other Belgian parties. Its messages are a copy-book example of populism.

NINJA connects the co-repressor TOPLESS to jasmonate signalling

Abstract: Jasmonoyl-isoleucine (JA-Ile) is a plant hormone that regulates a broad array of plant defence and developmental processes. JA-Ile-responsive gene expression is regulated by the transcriptional activator MYC2 that interacts physically with the jasmonate ZIM-domain (JAZ) repressor proteins. On perception of JA-Ile, JAZ proteins are degraded and JA-Ile-dependent gene expression is activated. The molecular mechanisms by which JAZ proteins repress gene expression remain unknown. Here we show that the Arabidopsis JAZ proteins recruit the Groucho/Tup1-type co-repressor TOPLESS (TPL) and TPL-related proteins (TPRs) through a previously uncharacterized adaptor protein, designated Novel Interactor of JAZ (NINJA). NINJA acts as a transcriptional repressor whose activity is mediated by a functional TPL-binding EAR repression motif. Accordingly, both NINJA and TPL proteins function as negative regulators of jasmonate responses. Our results point to TPL proteins as general co-repressors that affect multiple signalling pathways through the interaction with specific adaptor proteins. This new insight reveals how stress-related and growth-related signalling cascades use common molecular mechanisms to regulate gene expression in plants.

Assurance on sustainability reports: an international comparison

Abstract: Globally, companies increasingly publish separate general purpose, nonfinancial (sustainability) reports. Some of these are independently assured and assurers may or may not be from the auditing profession. We seek to understand this emerging voluntary assurance market. Using a sample of 2,113 companies (from 31 countries) that produced sustainability reports between 2002–2004, we use sequential logit analysis to identify the factors associated with the decision to voluntarily purchase assurance and the choice of assurance provider. We hypothesize that a company's need to enhance credibility through assurance and choice of assurance provider will be a function of company‐, industry‐, and country‐related factors. Our results support the argument that companies seeking to enhance the credibility of their reports and build their corporate reputation are more likely to have their sustainability reports assured, although it does not matter whether the assurance provider comes from the auditing profes...
