Of bulls and bulbs: aspirations, opinions and perceptions of rural adolescents and youth in Zambia
(2018-07)In Africa, policymakers and development practitioners focus heavily on making farming more attractive for the youth. To reach this goal, different actions are proposed, often emphasising the need for modern technology. ... -
Of Liars and Deniers: The Credibility-Concealed Information Test as a Response Time-Based Measure for Credibility Assessment in Suspects and Witnesses
(2020-02-26)There are numerous studies on polygraphs like the Concealed Information Test (CIT) that aim to detect whether a suspect possesses crime-related knowledge. In contrast, not a single psychophysiological or behavioral paradigm ... -
Of Trackers and Tractors. Using a Smartphone App and Compositional Data Analysis to Explore the Link Between Mechanization and Intra-Household Allocation of Time in Zambia
(2019-05)Digital tools may help to study socioeconomic aspects of agricultural development that are difficult to measure such as the effects of new technologies, policies and practices on the intra-household allocation of time. As ... -
Off the Grid: Environmental Degradation and Citizenship at the Margins
(2015-05)In this paper I have presented some preliminary thoughts on political repercussions of environmental degradations on the margins. In order to do that I have embraced two approaches derived from political theory. First, I ... -
Off-Label-Use von Arzneimitteln in der Palliativmedizin
(2013-05-07)Es steht außer Frage, dass die gesundheitliche Versorgung unserer Gesellschaft durch den medizinischen Fortschritt in den letzten Jahrzehnten enorm gesteigert wurde. Dabei ist der Schwerpunkt dieser Entwicklung auf Heilung ... -
OIKOS 2010 – Haushalte und Familien im Modernisierungsprozess: Festschrift für Prof. Dr. Barbara Seel zum 65. Geburtstag
(2007)Der Wandel vom fürsorgenden zum aktivierenden Sozialstaat ist eine Herausforderung für die Menschen in Deutschland. Dieser Band bietet eine Bestandsaufnahme der Folgen für Haushalte und Familien als auch der Möglichkeiten, ... -
Okklusionsmorphologische Anpassungsmechanismen der Zähne: Eine Langzeitstudie
(2013-07-23)Das Ziel dieser klinischen Langzeitstudie war die Analyse der morphologischen Veränderung der Okklusalfläche über einen Zeitraum von 5 Jahren. Dabei sollte mittels verschiedener Methoden die Frage beantwortet werden, ob ... -
Old Globular Clusters in Dwarf Irregular Galaxies
(2008)One of the most pressing questions in astrophysics to date is resolving the history of galaxy assembly and their subsequent evolution. In the currently popular hierarchical merging” scenario, massive galaxies are believed ...

Oligozäne Beckendynamik und Sequenzstratigraphie am Südrand des Nordwesteuropäischen Tertiärbeckens
(2004)Durch die Analyse von Bohrdaten aus 230 Explorations- und Forschungsbohrungen wird für die oligozäne Sedimentfüllung am Südrand des Nordwesteuropäischen Tertiärbeckens zwischen Belgien im Westen und Sachsen-Anhalt im Osten ... -
The Olov Janse Collection: Material Evidence for the Han Viet Burial Tradition
(2023-12-15)In the 1930s, the Swedish archeologist Olov Robert Thure Janse conducted excavation expeditions in Indochina. His expeditions revealed brick tombs in North Vietnam during a period when Vietnam was under the occupation of ... -
On a Civilizing Mission: Die imperiale Zivilisierungspropaganda in den USA und im Deutschen Kaiserreich, 1889-1914
(2006)Die Dissertation beschäftigt sich mit der imperialen Propaganda in den USA zwischen 1889 und 1914. Im Zentrum steht dabei ein besonderer Aspekt der Propaganda: das Thema Zivilisierung sowie die damit verbundenen Begriffe ... -
On a kinetic equation arising in weak turbulence theory for the nonlinear Schrödinger equation
(2016-12-22)We present a study of weak solutions to a kinetic equation of coagulation-fragmentation type. This quadratic equation (QWTE) is the leading order approximation for long times to the isotropic space-homogeneous weak turbulence ... -
On a non-local free boundary problem modeling cell polarization
(2022-11-08)The amplification of an external signal is a key step in direction sensing of biological cells, a process that contributes significantly in the regulation of cell shape. This thesis is concerned with a simple model for ... -
On affine Deligne-Lusztig varieties for GLn
(2005)In the first part of this thesis we study the global structure of moduli spaces of quasi-isogenies of p-divisible groups introduced by Rapoport and Zink. We determine their dimensions and their sets of connected components ... -
On Analysis of some Nonlinear Systems of Partial Differential Equations of Continuum Mechanics
(2003)In this thesis we consider systems of partial differential equations of continuum mechanics and analyze regularity properties of their weak solutions.
The first chapter contains a detailed introduction and reviews ... -
On Approximability of Bounded Degree Instances of Selected Optimization Problems
(2013-08-07)In order to cope with the approximation hardness of an underlying optimization problem, it is advantageous to consider specific families of instances with properties that can be exploited to obtain efficient approximation ... -
On Approximability, Convergence, and Limits of CSP Problems
(2016-09-16)This thesis studies dense constraint satisfaction problems (CSPs), and other related optimization and decision problems that can be phrased as questions regarding parameters or properties of combinatorial objects such as ... -
On arithmetic families of filtered φ-modules and crystalline representations
(2011-05-10)We consider stacks of filtered phi-modules over rigid analytic and adic spaces. We show that these modules parametrize p-adic Galois representations of the absolute Galois group of a p-adic field with varying coefficients ... -
On arithmetic properties of Fuchsian groups and Riemann surfaces
(2015-02-11)In this thesis, Riemann surfaces and their fundamental groups are studied from an arithmetic point of view. First the image of the absolute Galois group of a number field under Grothendieck's representation with values in ... -
On Avoidance and Neglect as Barriers to Informed Decision-Making: Three Essays in Behavioral Economics
(2014-08-07)The thesis comprises three essays on the reasons for and consequences of poorly-informed decision-making.
Chapter 1 investigates active avoidance of information as a source of uninformed decision-making. Next to ...
