Cultural response to totalitarianism in select movies produced in Czechoslovakia, Hungary and Poland between 1956 and 1989

Robak, Kazimierz 01 June 2009 (has links)
This study examines resistance against totalitarian propaganda in select movies produced in regions subjected to Soviet-imposed totalitarian system. From 1939 to the collapse of the Soviet Union in 1991, Central-Eastern Europe has experienced two of the most devastating and genocidal political systems in the history of the humankind. Nazism was destroyed with the end of WWII, and met widespread condemnation. Sovietism, commonly known as Communism, survived WWII and the Soviet totalitarian empire rose to the position of the world's second superpower. Effective and organized Soviet propaganda generated a new convincing image of Sovietism as a harmless, friendly and progressive system. In this situation, the extremely important role of maintaining moral consciousness has fallen to the artistic world, specifically film. The scope of my thesis is to explore and analyze the responses to the Soviet totalitarianism in movies produced in European states of the Soviet bloc, between 1956 and 1989. My thesis aims to offer a critical reading of the chosen movies as well as their historical and political conditions. I point out how filmmakers articulated their resistance and analyze it in the context of national culture. The movies I chose to discuss express the reality of everyday life during the Soviet era. Their dissection reflects the mutual influence of history and art in general and in the Soviet bloc in particular. Hence, I offer a reading of the past expressed in the subjective vision of the cinematographic art. Movies not only reflect certain fragments of the reality, they also play an important role in constructing a collective memory. Discussing them from this angle leads to an understanding of the current perception of the past in those countries.

Hydrogen electrochemistry in room temperature ionic liquids

Meng, Yao January 2012 (has links)
This thesis primarily focuses on the electrochemical properties of the H<sub>2</sub>/H<sup>+</sup> redox couple, at various metallic electrodes in room temperature ionic liquids. Initially, a comprehensive overview of room temperature ionic liquids, RTILs, compared to conventional organic solvents is presented which identifies their favourable properties and applications, followed by a second chapter describing the basic theory of electrochemistry. A third chapter presents the general experimental reagents, instruments and measurements used in this thesis. The results presented in this thesis are summarized in six further chapters and shown as follows. (1) Hydrogenolysis, hydrogen loaded palladium electrodes by electrolysis of H[NTf<sub>2</sub>] in a RTIL [C<sub>2</sub>mim][NTf<sub>2</sub>]. (2) Palladium nanoparticle-modified carbon nanotubes for electrochemical hydrogenolysis in RTILs. (3) Electrochemistry of hydrogen in the RTIL [C<sub>2</sub>mim][NTf<sub>2</sub>]: dissolved hydrogen lubricates diffusional transport. (4) The hydrogen evolution reaction in a room temperature ionic liquid: mechanism and electrocatalyst trends. (5) The formal potentials and electrode kinetics of the proton_hydrogen couple in various room temperature ionic liquids. (6) The electroreduction of benzoic acid: voltammetric observation of adsorbed hydrogen at a Platinum microelectrode in room temperature ionic liquids. The first two studies show electrochemically formed adsorbed H atoms at a metallic Pt or Pd surface can be used for clean, efficient, safe electrochemical hydrogenolysis of organic compounds in RTIL media. The next study shows the physicochemical changes of RTIL properties, arising from dissolved hydrogen gas. The last three studies looked at the electrochemical properties of H<sub>2</sub>/H<sup>+</sup> redox couple at various metallic electrodes over a range of RTILs vs a stable Ag/Ag<sup>+</sup> reference couple, using H[NTf<sub>2</sub>] and benzoic acid as proton sources. The kinetic and thermodynamic mechanisms of some reactions or processes are the same in RTILs as in conventional organic or aqueous solvents, but other remarkably different behaviours are presented. Most importantly significant constants are seen for platinum, gold and molybdenum electrodes in term of the mechanism of proton reduction to form hydrogen.
