Die Veränderung der individuellen politischen Kommunikation ist ein wesentliches Element des Konzepts der Mediatisierung des Politischen. Immer mehr Politikerinnen und Politiker sowie Bürgerinnen und Bürger nutzen digitale Plattformen, um sich politisch auszutauschen und zu informieren. Dabei stellt sich die Frage, inwiefern Politiker/-innen selbst Austauschmöglichkeiten im Netz bieten und somit direkt Kommunikation fördern. Für die vorliegende Studie wurde die Nutzung des Microblogging-Dienstes Twitter durch Politiker/-innen während ausgewählter Landtagswahlkämpfe des Jahres 2011 auf partizipationsermöglichende Elemente hin untersucht. Diese Elemente wurden mithilfe des „Funktionalen Operatorenmodells“ systematisiert und kategorisiert. Die Ergebnisse verdeutlichen nicht nur eine individuell ausgeprägte Nutzungsfrequenz der einzelnen Politiker/-innen, sondern auch unterschiedliche Stile der Twitternutzung, die sich als „persönlich-interaktiv“ und „thematisch-informativ“ klassifizieren lassen. In Einblick auf deliberative Strukturen ist die Twitterkommunikation im Politiker-Bürger-Dialog hingegen noch ausbaufähig.
In multimodal scholarly presentations supported by presentation software, spoken and written language, various visualizations on the projected slides as well as the contributors’ gestures and facial expressions build a meaningful oneness. On the one hand, communication scientists as well as linguists have for a relatively long time neglected the presentation as a complex form of communication. On the other hand, since Tafte (2003 ), columnists of major German newspapers have been dealing with the question of the value, the quality and the place of PowerPoint in science, they have even tried to find the answer to the question whether PowerPoint is evil or not.
The presentation practice is perceived as fundamentally deficient of systematic empirical research on presentations. Also Grabowski called attention to this desideratum with two critical articles (Grabowski 2003, 2008). Various questions - still unanswered - have motivated the implementation of a number of experiments (in the summer of 2010) for analyzing the knowledge and learning effects and the communicational impact of scientific presentations. The general aim of these experiments was to conduct empirical research on selected presentations in order to find out what kind of presentation is successful. The main interest is to find out which model of scholarly presentation produces the best results regarding learning effect and communicative impact.
We had found ourselves in the “Gutenberg-Galaxy” before the digitalization made its rise. The development of the book printing by Johannes Gutenberg and developments based on it as well as the following industrialization of printing are decisive for the expansion of the cultural revolution. It has meanwhile been transformed, upgraded and replaced by something which has been called “Turing Galaxy”. One of the most important changes is the automatic processing of data, the program-controlled production or manipulation of texts, images, sounds, formulas, tables and videos. The internet has led us to new distribution channels. The paper shows which trends of development concerning the cultural skills of writing and reading have been realized up to now as a result of the digitalization. Three aspects of development will be discussed: how the way of writing has changed to the present moment by the means of automation, multimodality and networking.
Wissenschaftliche Kommunikation zeichnet sich durch ein besonders hohes Maß an Standardisierung und Organisation aus. Anforderungen der Objektivität, der Nachvollziehbarkeit und der Authentizität schlagen sich in der Struktur aller wissenschaftlichen Textsorten nieder. Die Kulturtechniken der Schrift sind auf diese Bedingungen ausgerichtet, weshalb das Lesen und Schreiben wissenschaftlicher Texte traditionell besonderen Bedingungen unterliegt, die üblicherweise im Studium vermittelt werden. In diesem Beitrag soll zunächst gezeigt werden, welches die wichtigsten wissenschaftlichen Textsorten sind, welche Eigenschaften sie besitzen und welche Ziele mit Ihnen kommunikativ verfolgt werden. Im zweiten Abschnitt geht es um die Digitalisierung von Texten: Welche Merkmale besitzen digitale Texte und welchen technischen Bedingungen unterliegen sie. Auch wird es hier um das Schreiben digitaler Texte überhaupt gehen. Im letzten Abschnitt dieses Beitrags sehen wir uns die Auswirkungen daraus auf die wissenschaftliche Kommunikation an. Digitale Texte weisen Eigenschaften auf, die die kommunizierten Inhalte zu verändern vermögen. Wie ändert sich das wissenschaftliche Schreiben dadurch?
We present an experimental approach to determining natural dimensions of story comparison. The results show that untrained test subjects generally do not privilege structural information. When asked to justify sameness ratings, they may refer to content, but when asked to state differences, they mostly refer to style, concrete events, details and motifs. We conclude that adequate formal models of narratives must represent such non-structural data.
A formal narrative representation is a procedure assigning a formal description to a natural language narrative. One of the goals of the computational models of narrative community is to understand this procedure better in order to automatize it. A formal framework fit for automatization should allow for objective and reproducible representations. In this paper, we present empirical work focussing on objectivity and reproducibility of the formal framework by Vladimir Propp (1928). The experiments consider Propp’s formalization of Russian fairy tales and formalizations done by test subjects in the same formal framework; the data show that some features of Propp’s system such as the assignment of the characters to the dramatis personae and some of the functions are not easy to reproduce.
A frequently replicated finding is that higher frequency words tend to be shorter and contain more strongly reduced vowels. However, little is known about potential differences in the articulatory gestures for high vs. low frequency words. The present study made use of electromagnetic articulography to investigate the production of two German vowels, [i] and [a], embedded in high and low frequency words. We found that word frequency differently affected the production of [i] and [a] at the temporal as well as the gestural level. Higher frequency of use predicted greater acoustic durations for long vowels; reduced durations for short vowels; articulatory trajectories with greater tongue height for [i] and more pronounced downward articulatory trajectories for [a]. These results show that the phonological contrast between short and long vowels is learned better with experience, and challenge both the Smooth Signal Redundancy Hypothesis and current theories of German phonology.
The perception of syllable prominence depends to a limited extent on the acoustic properties of the speech signal in question. Psychoacoustic factors are involved as well. Thus, research often relies on two types of data: subjective prominence ratings collected in perception experiments and acoustic measures. A problem with the rating data is noise resulting from individual approaches to the rating task. This paper addresses the question of how this noise can be reduced by normalization, evaluating 12 normalization methods. In a perception experiment, prominence ratings concerning German read speech were collected. From the raw rating data 12 different ‘mirror’ data-sets were computed according to the 12 methods. Each mirror data-set was correlated with the same set of underlying acoustic data. The multiple regression setup included raw syllable duration as well as within-syllable maximum F0 and intensity. Adjusted r2-values could beraised considerably with selected methods.
Dieses Papier diskutiert informationsstrukturelle Aspekte der mehrfachen Vorfeldbesetzung im Deutschen. Auf der Grundlage einer größtenteils aus den IDS-Korpora extrahierten Belegsammlung werden Diskursgegebenheit, Fokus- und Topikstatus (vor allem) des Vorfeldmaterials beschrieben und in Bezug zu entsprechenden Aussagen in der Literatur gesetzt. Neben informationsstrukturellen Faktoren werden im letzten Abschnitt mögliche weitere Faktoren angesprochen, die mehrfache Vorfeldbesetzung favorisieren könnten. Zudem werden für einen begrenzten Ausschnitt des Deutschen erstmals Zahlen vorgelegt, die das Verhältnis von mehrfacher Vorfeldbesetzung zur ähnlichen, aber als „kanonischer“ geltenden Besetzung des Vorfelds mit einer (möglicherweise partiellen) Verbalphrase illustrieren.
This article deals with three interrelated phenoma in the information structure of German sentences: the focusing of negative markers, of finite verb forms and of the particles ja, doch, wohl and schon. Focusing of the finite verb is the most important marker of verum focus, as described by Höhle (1988). Focusing of particles can be an alternative means for similar purposes, while focusing of negation seems to be the contradictory opposite of verum focus. It is shown that negation- independently of its information structural status - can be interpreted on three distinct levels of sentence meaning: as an indicator of the non-facticity of a state of affairs, the non-truth of a proposition, or the non-desirability of a speech act. Focusing of the negative marker puts contrastive emphasis on the negative value assigned to sentence meaning on one of these levels. Ve rum focus can be interpreted on the same three levels: as a marker of contrastive emphasis on a positive value of facticity, truth or desirability. The particles ja, doch, wohl and schon refer to sufficient epistemic or interactional conditions for the assignment of a positive or negative value. By focusing such a particle, the speaker indicates that (s)he believes the assigned value to be well justified and insists on establishing it as common ground for further interaction.
