Political Humor as a confrontational tool against the Syrian regime: A study case: Syria, 15th March 2011 – 15th May 2012

The aim of this working paper is to analyze the inclusion of political humor into the set of actions used by opponents to the Syrian regime during the first year of a state-wide uprising in 2011. The research argues that although political humor has traditionally been seen mainly as a concealed voice against dominant elites, it can nevertheless take a confrontational stance and challenge a regime. In this paper we assess the role of political humor in challenging the legitimacy of the Syrian State through the battle for the signification of events. We will work with a theoretical framework that draws its assumptions from social movements’ studies and cultural studies. Through the assessment of the importance of discourse and the role of ideological domination to a regime we will see how the first year of the Syrian uprising included widespread acts of political humor as part of the strategy against the regime.

Alkaline phosphatase activity as a tool for assessing nutritional conditions in the seagrass Posidonia oceanica.(L.) Delile

The effects of experimental phosphorus enrichments on alkaline phosphatase activity (APA) of the seagrass Posidonia oceanica (L.) Delile were tested. Short-term additions (as phosphate, 12 hours, in the laboratory) decreased APA by 18-2896, depending on the plant part considered (roots, young leaves or old leaves). The values of APA after this treatment were well correlated with interna1 phosphorus pools (as P concentration in plant tissues). Long-term additions (as phosphate, added to the sediment, 1 month in situ) decreased APA by 40-75%, also depending on the plant part. We conclude that alkaline phosphatase activity is a good indicator of P deficiency in this seagrass. We used this indicator to assess the P-nutritional status in a series of meadows in the NW Mediterranean, finding a high geographical variability, but correlations between APA and basic features of the meadows (carbonate content of the sediment, organic content of the sediment, shoot density, etc.) were not significant. Consequently, phosphorus deficiency does not seem to be directly related to these descriptors.
