Determination of pesticides enantiomers in water
Šlechtová, Tereza ; Tesařová, Eva (advisor) ; Lokajová, Jana (referee)
This Barchelor's project deals with chiral herbicide mecoprop and its determination by high-performance liquid chromatography method with teicoplanin based chiral stationary phase. The teoretical part focus on basic facts conserning chirality, chiral pesticides and problems related to their usage and effects to the enviroment. It also involves the ways of their determination by the above mentioned method and gives several examples of previous separations. The experimental part is based on method optimalization and determination of changes in mecoprop enantiomeric ratio in various water samples during different storage conditions.

Communicative strategies of politicians in interaction.
Lokajová, Jana ; Šaldová, Pavlína (advisor) ; Klégr, Aleš (referee)
Abstract. The aim of this M.A. thesis is to apply on the sample of five transcribed interviews with American politicians the typology of strategies devised by social psychologists P. Bull and K. Mayer (1993) for 'non-replies' of British politicians in the genre of a political interview and to determine whether this typology could be qualitatively correlated to specific linguistic means (the use of passive, pronominal shifts, hedges). The responses of politicians are examined within the CDA method also in relation to the macro-principles of evasion (dissimulation), coercion, legitimation and delegitimation, which are claimed to be valid in political discourse by P. Chilton (2004) in order to discover whether Bull and Mayer's social typology could be related to these principles and to the strategies of face-management (Brown and Levinson 1987). It is expected that politicians will boost their positive image in the interview and coerce the public in the agenda shift (Clayman, Heritage 2002) through every response in the interview. A question which according to Bull and Elliott (1996) consists of face threat is also expected to be attacked; quantitative results are presented which verify this assumption. In addition, as thirty strategies were observed to have been employed by Mrs Thatcher and Neil Kinnock in...
