Oppositional Political Identity in the Song Culture of the Vormärz and the 1848 Revolution in Germany

Historically political song has often been perceived negatively, as a disturbance of the peace, summed up by the legendary line from Goethe’s Faust: “Politisches Lied – ein garstiges Lied”. In the period in Germany of the Vormärz (from 1815 up to the revolution of March 1848), however, we see how this perception may be changing as it increasingly becomes a means of self-expression in public life. This was the era of restauration, in which broader sections of German society are striving for political emancipation from the princes and kings. A whole host of political themes emerge in the songs (Freiheitslieder) of that period in which a new oppositional political consciousness is reflected. The themes range from freedom of speech, freedom from censorship, and the need for democratic and national self-determination to critiques of injustice and hunger, and parodies of political convention and opportunism. Sources of reception give indications about the social and political milieus in which these songs circulated. Such sources include broadsheets, handwritten manuscripts, song collections, commemoration events, advertisements in political press, memoires, police reports and general literature of the time. In many cases we see how these songs reflect the emerging social and political identities of those who sing them. One also sees the use of well known melodies in the popular dissemination of these songs. An intertextual function of music often becomes apparent in the practice of contrefacture whereby melodies with particular semantic associations are used to either underline the message or parody the subject of the song.

Density functional study of the C atom adsorption on the α-Fe 2O3 (001) surface

The adsorption of C atoms on the α-Fe₂O₃ (001) surface was studied based on density function theory (DFT), in which the exchange-correlation potential was chosen as the PBE (Perdew, Burke and Ernzerhof) generalized gradient approximation (GGA) with a plane wave basis set. Upon the optimization on different adsorption sites with coverage of 1/20 and 1/5 ML, it was found that the adsorption of C atoms on the α-Fe ₂O₃ (001) surface was chemical adsorption. The coverage can affect the adsorption behavior greatly. Under low coverage, the most stable adsorption geometry lied on the bridged site with the adsorption energy of about 3.22 eV; however, under high coverage, it located at the top site with the energy change of 8.79 eV. Strong chemical reaction has occurred between the C and O atoms at this site. The density of states and population analysis showed that the s, p orbitals of C and p orbital of O give the most contribution to the adsorption bonding. During the adsorption process, O atom shares the electrons with C, and C can only affect the outermost and subsurface layers of α-Fe₂O₃; the third layer can not be affected obviously.
