Zusammenfassung – nichtamtliche Leitsätze:
• Ein allgemeines Burkaverbot in der Öffentlichkeit verstößt nicht gegen Art. 8 oder 9
EMRK.
• Das Tragen einer Burka unterfällt als private Lebensführung dem Schutzbereich des
Art. 8 EMRK sowie als Religionsausübung dem Schutzbereich des Art. 9 EMRK.
• Ein allgemeines Burkaverbot in der Öffentlichkeit zum Schutz der Sicherheit verfolgt
ein legitimes Ziel, ist in Ermangelung einer allgemeinen Gefahr aber nicht erforderlich
und damit unverhältnismäßig.
• Der Schutz des Respekts für die Gleichheit von Mann und Frau oder für die Menschenwürde
lässt sich nicht als legitimes Ziel für ein Burkaverbot heranziehen.
• Der Schutz des Respekts für die Minimalbedingungen gesellschaftlichen Zusammenlebens
stellt ein legitimes Ziel für ein Burkaverbot dar. Das Burkaverbot ist angesichts
des breiten staatlichen Ermessensspielraums in einer solchen Frage nicht unverhältnismäßig.
Microsaccades
(2015)
The first thing we do upon waking is open our eyes. Rotating them in our eye sockets, we scan our surroundings and collect the information into a picture in our head. Eye movements can be split into saccades and fixational eye movements, which occur when we attempt to fixate our gaze. The latter consists of microsaccades, drift and tremor. Before we even lift our eye lids, eye movements – such as saccades and microsaccades that let the eyes jump from one to another position – have partially been prepared in the brain stem. Saccades and microsaccades are often assumed to be generated by the same mechanisms. But how saccades and microsaccades can be classified according to shape has not yet been reported in a statistical manner. Research has put more effort into the investigations of microsaccades’ properties and generation only since the last decade. Consequently, we are only beginning to understand the dynamic processes governing microsaccadic eye movements. Within this thesis, the dynamics governing the generation of microsaccades is assessed and the development of a model for the underlying processes. Eye movement trajectories from different experiments are used, recorded with a video-based eye tracking technique, and a novel method is proposed for the scale-invariant detection of saccades (events of large amplitude) and microsaccades (events of small amplitude). Using a time-frequency approach, the method is examined with different experiments and validated against simulated data. A shape model is suggested that allows for a simple estimation of saccade- and microsaccade related properties. For sequences of microsaccades, in this thesis a time-dynamic Markov model is proposed, with a memory horizon that changes over time and which can best describe sequences of microsaccades.
Several authors highlighted that the time course of an experiment itself could have a substantial influence on the interpretability of experimental effects. Since mixed effects modeling had enabled researchers to investigate more complex problems with more precision than before, two naming experiments were conducted with college students, with and without non-words intermixed, and analyzed with regard to frequency, quality, interactive and trial-history effects. The present analyses build on and extend the Bates, Kliegl, Vasishth, and Baayen (2015) approach in order to converge on a parsimonious model that accounts for autocorrelated errors caused by trial history. For three of four cases, a history-sensitive model improved the model fit over a history-naïve model and explained more deviance. In one of these cases, the herein presented approach helped reveal an interaction between stimulus frequency and quality that was not significant without a trial history account. Main and joint effects, limitations, as well as directions for further research, are briefly discussed.
Intuitively, it is clear that neural processes and eye movements in reading are closely connected, but only few studies have investigated both signals simultaneously. Instead, the usual approach is to record them in separate experiments and to subsequently consolidate the results. However, studies using this approach have shown that it is feasible to coregister eye movements and EEG in natural reading and contributed greatly to the understanding of oculomotor processes in reading. The present thesis builds upon that work, assessing to what extent coregistration can be helpful for sentence processing research.
In the first study, we explore how well coregistration is suited to study subtle effects common to psycholinguistic experiments by investigating the effect of distance on dependency resolution. The results demonstrate that researchers must improve the signal-to-noise ratio to uncover more subdued effects in coregistration. In the second study, we compare oscillatory responses in different presentation modes. Using robust effects from world knowledge violations, we show that the generation and retrieval of memory traces may differ between natural reading and word-by-word presentation. In the third study, we bridge the gap between our knowledge of behavioral and neural responses to integration difficulties in reading by analyzing the EEG in the context of regressive saccades. We find the P600, a neural indicator of recovery processes, when readers make a regressive saccade in response to integration difficulties.
The results in the present thesis demonstrate that coregistration can be a useful tool for the study of sentence processing. However, they also show that it may not be suitable for some questions, especially if they involve subtle effects.
MULTILIT
(2015)
This paper presents an overview of the linguistic analyses developed in the MULTILIT project and the processing of the oral and written texts collected. The project investigates the language abilities of multilingual children and adolescents, in particular, those who have Turkish and/or Kurdish as a mother tongue. A further aim of the project is to examine from a psycholinguistic and sociolinguistic perspective the extent to which competence in academic registers is achieved on the basis of the languages spoken by the children, including the language(s) spoken at the home, the language of the country of residence and the first foreign language. To be able to examine these questions using corpus linguistic parameters, we created categories of analysis in MULTILIT.
The data collection comprises texts from bilingual and monolingual children and adolescents in Germany in their first language Turkish, their second language German und their foreign language English. Pupils aged between nine and twenty years of age produced monologue oral and written texts in the two genres of narrative and discursive. On the basis of these samples, we examine linguistic features such as lexical expression (lexical density, lexical diversity), syntactic complexity (syntactic and discursive packaging) as well as phonology in the oral texts and orthography in the written texts, with the aim of investigating the pupils’ growing mastery of these features in academic and informal registers.
To this end the raw data have been transcribed by the use of transcription conventions developed especially for the needs of the MULTILIT data. They are based on the commonly used HIAT and GAT transcription conventions and supplemented with conventions that provide additional information such as features at the graphic level.
The categories of analysis comprise a large number of linguistic categories such as word classes, syntax, noun phrase complexity, complex verbal morphology, direct speech and text structures. We also annotate errors and norm deviations at a wide range of levels (orthographic, morphological, lexical, syntactic and textual). In view of the different language systems, these criteria are considered separately for all languages investigated in the project.
Die Schule steckt mitten in einem Umbruch: Dieser wird durch verschiedene Faktoren wie sinkende Schülerzahlen, Zu- und Abwanderungen von Familien mit ihren Kindern, wachsenden Zahlen von Schulpflichtigen mit Migrationshintergrund und anderes mehr gekennzeichnet. Damit steht die Schule vor neuen Herausforderungen. Außerdem hält der Trend zum Gymnasium an. Auch wechselvolle Dauerreformen schaffen unübersichtliche Schulstrukturen und erschweren sichere Orientierung. Und: Im zunehmend raueren Wettbewerb der Schultypen laufen den öffentlichen Schulen immer mehr Schüler davon und zu den Privatschulen über. Schon jetzt sehen sich zahlreiche Kommunen gezwungen, ihre Bildungsangebote zurückzuschrauben und ihre Schulen zu schließen.
Kann eine Kommune ihren Bürgern aber nicht mehr die schulische „Grundversorgung“ anbieten, so hat dies weitreichende Folgen. Wo Schulen schließen müssen, „stirbt auch der Ort“. Ein umfangreiches, vielfältiges und flächendeckendes Bildungsangebot dagegen ist für die Kommune tragender Pfeiler einer funktionsfähigen Infrastruktur. Hier setzt die 21. Fachtagung des Kommunalwissenschaftlichen Institutes der Universität Potsdam an. Sie behandelt zentrale Themen der nachhaltigen Gewährleistung schulischer Infrastruktur in den Kommunen einschließlich der dazugehörigen Erfahrungsberichte, die über Best-Practice-Modelle sowie über Erfolgsbedingungen und Fallstricke in der Verwaltungspraxis informieren. Damit gibt die Tagung zugleich Impulse den kommunalen Entscheidungsträgern für die Generierung von und den Umgang mit Gestaltungsoptionen zur Standortsicherung im kommunalen Bildungsmanagement.
