Ethnic Mobilization in the Former Yugoslavia as a Kind of Structural Setting and Framing
No full textAbstractThe author claims that strategies of ethnic mobilization have deep roots in the politics of ex-Yugoslav nations, and that these roots are closely related to the response of the Western Balkans, especially Serbian political elites, to the challenges of democratization and modernization. The author develops this notion in two basic sections, outlining the ontology and history, and psychological background of the ethnic mobilization. Beyond the larger historical perspective, which will be reviewed, the very source of current ethno-mobilization processes lies in the deep opposition of Serbian political elites to the loose federal Yugoslav Constitution of 1974 that initiated various political strategies of ethno-mobilization's undermining and neglect. The author understands the term 'ethnic mobilization' to have three layers of meaning, the first being most rudimentary: an orderly and phased procedure aimed at ethnic crystallization or homogenization of Serb people. The second layer encompasses the underlying framing narrative of the reinterpretation of certain social events or conflicts within a particular interpretative frame or 'code.' The third meaning is, in a very important sense, demobilization, namely, the competing elites had to be demobilized, neutralized, or marginalized, and were usually described as ethnic 'traitors,' or 'those who sold to the interests of the enemy, or of the West.' Based on ideas of Latinka Perović and Dubravka Stojanović, the author traces the roots of the ethnopolitics back to the Russian anti-modernist movement of 'narodnichestvo.' This anti-Western and deeply anti-democratic strategy of political power lies at the heart of violent conflicts in Slovenia, Croatia, Bosnia and Herzegovina, Serbia/Kosovo, and even Macedonia. And, in the author's view, it remains the key obstacle to a post-war democratic transition for these countries. Strategies of ethnic mobilization remain, up to the present day, the driving force of power structures in these countries.

Inclusive Measurement of the Charm Contribution to the Structure Function of the Proton
No full textThe inclusive measurement of charm production in deep inelastic scattering with the ZEUS detector at HERA is presented in this thesis. In a first step, the existing algorithm from the inclusive secondary vertexing analysis was generalised using the signed impact parameter of jet-associated tracks to extract the heavy quark content of the data sample. In a second step, the algorithm was extended by using the decay vertex in events containing a well-reconstructed secondary vertex, the impact parameter in events not containing a secondary vertex, and a combination of vertexing and tracking information in all other events. The combined algorithm has reduced the relative statistical and systematic uncertainties on the measured double differential cross sections in Q2 and x. The relative statistical error has been reduced by 40 % on average, whilst the systematic uncertainty decreased due to an improved tracking efficiency. In order to extend the kinematic region and further reduce the uncertainty on the extrapolation of the charm contribution, F2cc, to the structure function of the proton the cut on the transverse jet energy has been relaxed from ET > 4.2 GeV to ET > 2.5 GeV. An extrapolation of the visible cross sections to the full kinematic phase space was performed allowing an extraction of F2cc to be made for a well-defined set of points in the x and Q2 plane. A comparison with previous results shows that lowering the cut on the transverse energy has particularly reduced the uncertainty on the extrapolation in the low Q2 and low x region. The present analysis is well described by next-to-leading order QCD predictions generated with the HVQDIS program. At present it is the most precise measurement of charm production cross sections with the ZEUS detector, and will have a significant impact on future combinations of ZEUS and H1 data
Design und Synthese von Bumetanid-Derivaten mit Benzylamin-Teilstruktur
No full textDas Ziel dieser Diplomarbeit war es Bumetanidderivate zu synthetisieren. Bei den meisten Derivaten wurde die Carbonsäure durch unterschiedliche Strukturen substituiert. Die daraus resultierenden Produkte könnten die Blut-Hirn-Schranke leichter durchqueren und dann den Na+-K+-2Cl--Symporter im ZNS inhibieren. Das könnte zu vielversprechenden Effekten führen, als Zusatz zur derzeitigen Therapie von Glioma und Schlaganfällen. Insgesamt wurden 13 Substanzen synthetisiert, wobei bei Substanz 1 – 11 die Carboxylgruppe von Bumetanid substituiert wurde. Substanz 12 und 13 haben nur die Teilstruktur der Sulfonamidgruppe und des Phenylringes mit Bumetanid gemeinsam.The objective of this diploma thesis was to synthesize bumetanide derivates. For most of the derivates the carboxylic acid function was substituted with different structures. The resulting products could possibly enter the blood-brain barrier more easily and then inhibit the Na+-K+-2Cl--Symporter in the CNS. This could lead to some promising effects, as an add-on to the current therapy of glioma and stroke. In total 13 compounds were synthesized, compounds 1 – 11 were made by different substitutions of the carboxylic group. Compound 12 and 13 just have the substructure of the sulfonamide group and the phenyl ring in common with bumetanide
(Desperately) seeking the early modern self : the self, subjectivity, modernity and representation in Shakespeare's Hamlet
No full textThe aim of the thesis (Desperately) Seeking the Early Modern Self: The Self, Subjectivity, Modernity and Representation in Shakespeare s Hamlet is to explore the Early Modern self in Hamlet. A host of neo-Marxist new historicist and cultural materialist critics of the period in general and the play in particular have argued that there is no inner sense of self in Early Modern England. Hence Prince Hamlet cannot possibly claim to have that within which passes show simply because the play predates the year 1660 and the alleged inauguration of the capitalist state in England. Phenomena such as individuality, subjectivity and interiority are said to be the illusions of the new bourgeois class. Being the principal character of the pre-eminent play of transition between the Early Modern Period and the Enlightenment, Hamlet has been viewed as a prefiguration of the bourgeois fiction of the immaterial, interior subject, supposedly introduced by René Descartes Discourse on the Method of Rightly Conducting the Reason and Seeking Truth in the Sciences (1637). On the other hand, he has also been seen as genuinely possessing a meaningful inwardness that is diverse and in constant flux, which is allegedly the idea of the self as articulated in the Essays (1580-1595) by the Early Modern French author Michel de Montaigne. Hence Hamlet has been deemed both a Montaignesque and a Cartesian figure.
The exploration of the issue of the self in this thesis involves a study of the Early Modern self in general and in Hamlet in particular. My range of enquiry about the self is both synchronic - a slice through the play of Hamlet and its historical and cultural context - and to some extent diachronic, that is, a kind of historical narrative tracing the view of the modern self over time. My approach is interdisciplinary and involves the exploration of the Early Modern self in Hamlet with reference to works of literature and literary criticism as well as works on psychology and philosophy. An extensive theoretical discussion of the notion of the Early Modern self is supported by concrete examples from Hamlet and Early Modern literature as well as from Descartes and Montaigne s work.
I argue that the Early Modern person did have an individuated, subjective, inner sense of self -- it is to be found in literature before 1660, and it is very much in evidence in Hamlet. I also claim that the evidence of Hamlet s inwardness is to be found in his soliloquies. Finally, I argue that Shakespeare s Prince is a point of convergence between Montaigne s and Descartes subjectivity or modernity, harking back, as it were, to Montaigne and antiquity and pointing towards Descartes and our own time
Exploiting oligo(amido amine) backbones for the multivalent presentation of coiled-coil peptides
No full textThe investigation of coiled coil formation for one mono- and two divalent peptide-polymer conjugates is presented. Through the assembly of the full conjugates on solid support, monodisperse sequence-defined conjugates are obtained with defined positions and distances between the peptide side chains along the polymeric backbone. A heteromeric peptide design was chosen, where peptide K is attached to the polymer backbone and coiled coil formation is only expected through complexation with the complementary peptide E. Indeed, the monovalent peptide K-polymer conjugate displays rapid coiled coil formation when mixed with the complementary peptide E sequence. The divalent systems show intramolecular homomeric coiled coil formation on the polymer backbone despite the peptide design. Interestingly, this intramolecular assembly undergoes a conformational rearrangement by the addition of the complementary peptide E leading to the formation of heteromeric coiled coil-polymer aggregates. The polymer backbone acts as a template bringing the covalently bound peptide strands in close proximity to each other, increasing the local concentration and inducing the otherwise non-favorable formation of intramolecular helical assemblies

Inclusive-Jet Photoproduction at HERA and Determination of
No full textInclusive-jet cross sections have been measured in the reaction ep→e+jet+X for photon virtuality Q 2<1 GeV 2 and γp centre-of-mass energies in the region 14217 GeV and -1< jet<2.5. In addition, measurements of double-differential inclusive-jet cross sections are presented as functions of ETjet in different regions of jet. Next-to-leading-order QCD calculations give a good description of the measurements, except for jets with low ETjet and high jet. The influence of non-perturbative effects not related to hadronisation was studied. Measurements of the ratios of cross sections using different jet algorithms are also presented; the measured ratios are well described by calculations including up to O(αs2) terms. Values of α s(M Z) were extracted from the measurements and the energy-scale dependence of the coupling was determined. The value of α s(M Z) extracted from the measurements based on the k T jet algorithm is αs(MZ)=0.1206-0.0022+0.0023(exp.)-0.0035+0.0042(th.); the results from the anti-k T and SIScone algorithms are compatible with this value and have a similar precision. © 2012 Elsevier B.V
Combined inclusive diffractive cross sections measured with forward proton spectrometers in deep inelastic ep scattering at HERA
No full textA combination of the inclusive diffractive cross section measurements made by the H1 and ZEUS Collaborations at HERA is presented. The analysis uses samples of diffractive deep inelastic ep scattering data at a centre-of-mass energy √s= 318 Gev where leading protons are detected by dedicated spectrometers. Correlations of systematic uncertainties are taken into account, resulting in an improved precision of the cross section measurement which reaches 6 % for the most precise points. The combined data cover the range 2.5 < Q 2 < 200 GeV 2 in photon virtuality, 0.00035 < xP < 0.09 in proton fractional momentum loss, 0.09 <{pipe}t{pipe}< 0.55 GeV 2 in squared four-momentum transfer at the proton vertex and 0.0018 < β <0.816 in β=x/xP, where x is the Bjorken scaling variable. © 2012 The Author(s).0H1 and ZEUS CollaborationsSCOPUS: ar.jinfo:eu-repo/semantics/publishe
