Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
This paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories
Ungleichheitsstrukturen versus Vielfalt der Lebensführungen: warum die Ungleichheitsforschung die Differenzierungstheorie konsultieren sollte
"Der folgende Text bezieht sich auf die Veranstaltung 'Author Meets Critic', in der das Buch: Thomas Schwinn (Hrsg.), Differenzierung und soziale Ungleichheit. Die zwei Soziologien und ihre Verknüpfung, Frankfurt a.M. 2004 (2. Auflage 2004), diskutiert wurde. An der gut besuchten Veranstaltung nahmen neben dem Herausgeber Reinhard Kreckel, Hans-Peter Müller, Uwe Schimank und Markus Schroer teil. Thema des Buches wie der Diskussion war die Frage, wie die beiden makrosozialen Theorietraditionen der Soziologie, funktionale Differenzierung und soziale Ungleichheit, verknüpft werden können. Insbesondere stand die Frage im Mittelpunkt, welchen Erkenntnisgewinn soziale Ungleichheitsanalysen erwarten dürfen, wenn sie den Kontakt zur Differenzierungstheorie suchen. Die Kritiker klagten dabei eine genauere Klärung des Zusammenhangs der beiden Strukturdimensionen ein. Strittig blieb, ob es eine beide Aspekte integrierende Theorie geben könne oder ob man sich mit problembezogenen Verknüpfungen begnügen müsse. Der folgende Text greift diese Debatte auf und versucht, einige Antworten auf die aufgeworfenen Fragen zu geben." (Textauszug

Structure and Dynamics of Confined Liquids: Challenges and Perspectives for the X-ray Surface Forces Apparatus
The molecular-scale structure and dynamics of confined liquids has increasingly gained relevance for applications in nanotechnology. Thus, a detailed knowledge of the structure of confined liquids on molecular length scales is of great interest for fundamental and applied sciences. To study confined structures under dynamic conditions, we constructed an in situ X-ray surface forces apparatus (X-SFA). This novel device can create a precisely controlled slit-pore confinement down to dimensions on the 10 nm scale by using a cylinder-on-flat geometry for the first time. Complementary structural information can be obtained by simultaneous force measurements and X-ray scattering experiments. The in-plane structure of liquids parallel to the slit pore and density profiles perpendicular to the confining interfaces are studied by X-ray scattering and reflectivity. The normal load between the opposing interfaces can be modulated to study the structural dynamics of confined liquids. The confinement gap distance is tracked simultaneously with nanometer precision by analyzing optical interference fringes of equal chromatic order. Relaxation processes can be studied by driving the system out of equilibrium by shear stress or compression/decompression cycles of the slit pore. The capability of the new device is demonstrated on the liquid crystal 4'-octyl-4-cyano-biphenyl (8CB) in its smectic A (SmA) mesophase. Its molecular-scale structure and orientation confined in 100 nm to 1.7 mu m slit pores was studied under static and dynamic nonequilibrium conditions.The authors acknowledge the help of Thomas Buslaps (ESRF) at beamline ID31, Marie Ruat (ESRF) for support on the CdTe MAXIPIX detector, and Michael Kappl (MPI-P) for AFM measurements and thank Harald Reichert (ESRF), Milena Lippmann (PETRA III), and Hans-Jürgen Butt (MPI-P) for helpful discussions.

Fitness landscape analysis of dimensionally-aware genetic programming featuring feynman equations
Genetic programming is an often-used technique for symbolic regression: finding symbolic expressions that match data from an unknown function. To make the symbolic regression more efficient, one can also use dimensionally-aware genetic programming that constrains the physical units of the equation. Nevertheless, there is no formal analysis of how much dimensionality awareness helps in the regression process. In this paper, we conduct a fitness landscape analysis of dimensionally-aware genetic programming search spaces on a subset of equations from Richard Feynman’s well-known lectures. We define an initialisation procedure and an accompanying set of neighbourhood operators for conducting the local search within the physical unit constraints. Our experiments show that the added information about the variable dimensionality can efficiently guide the search algorithm. Still, further analysis of the differences between the dimensionally-aware and standard genetic programming landscapes is needed to help in the design of efficient evolutionary operators to be used in a dimensionally-aware regression.Accepted author manuscriptCyber Securit

Handledare: Mattias Gunnarsson, Thomas LaurienThis project explores the impact of furniture design in the home-lives of individuals who have transitioned from homelessness to independent housing. With an ethnographic approach, the author engages with Housing First tenants through the process of designing furniture based on their preferences. The project contemplates the right to adequate housing in relationship to a personal sense of home and proposes a role for designers within the context of Housing First

"BRÜDERLICHE EGOISTEN". DIE GEDICHTÜBERSETZUNGEN AUS DEM SPANISCHEN VON ERICH ARENDT UND HANS MAGNUS ENZENSBERGER
The authors and translators Erich Arendt and Hans Magnus Enzensberger are two key figures in German literature after 1945, known especially for their appropriation of foreign literatures. They both contributed extensively to the reception of Modern Latin American and Spanish Poetry in East and West Germany by translating poets such as Pablo Neruda, César Vallejo and Rafael Alberti. This is the first study to explore the asymmetrically intertwined literary conditions of the two author-translator figures with regard to the ways in which engaging with a foreign text opens up a perspective on the author-translator’s own poetology.Dissertation not available (per author's request)Dissertation restricted upon deposit / 10-Sep-2015, Kimberl
Beyond the Bosphorus? Comparing German, French, and British Discourses on Turkey's Application to Join the European Union. IHS Political Science Series Paper, No. 111, December 2006
This article examines the impact of national borders on public discourses, based on a case study of the struggle surrounding Turkey’s application to join the European Union (EU). Comparing opinions, reasons and interpretation patterns in press commentaries about enlarging the EU beyond the Bosphorus, the findings confirm the paramount importance and robustness of national cleavages between the German and the French public sphere on the one hand, and the British on the other. Whereas Turkish membership was predominantly re-jected on the continent, the British commentators strongly and almost unanimously sup-ported Ankara’s request to open doors. These similarities and divergences, I argue, are first and foremost the result of, and linked with, competing visions of Europe’s finality, especially regarding various constitutional ideas and cultural principles. Against this background, the Turkey question was partly exploited as an instrument supporting or repressing different conceptions of the European Union’s future
