Investigations into the burning-out of organic substances in the ceramic body

Pressed compacts were made of spray dried alumina containing water soluble polyvinyl alcohol or cellulose derivative binder. The burning out of organic binder on gradual heating was investigated by visual and microscopic observations of the cross section and by thermogravimetry. Burning out proceeds inward from the peripheries, gradually reducing the size of the black core, which first consists of a dark boundary layer and later turns uniformly black with a sharp boundary. A detailed mechanism of the burning out process between and within the spray dried granules is observed under the microscope. Oxygen atmosphere accelerates the burning out process

From Patient to Guest: Current trends in the German health care industry and their impacts on the tourism sector

Fuelled by demographic and psychographic change, the German health care system has been under increasing pressure over the past decades to a point where the system has been seen as no longer economically viable. This has set in motion a string of reform measures which have aimed to reign in the spiralling costs. Now, with a much greater focus on prevention, competition within the health care system and more personal responsibility, the German health sector is by many no longer perceived as a burden on the national economy but rather as an opportunity for furture economic growth. One important reason for this development has been an expansion in what is known as the second health care market. This paper outlines the shift from a public health insurance system to a modern health economy by focusing on the health tourism sector which has experienced a boom in recent years, driven particularly by strong demand in the senior market segment

An algorithm for clock synchronization with the gradient property in sensor networks

We introduce a distributed algorithm for clock synchronization in sensor networks. Our algorithm assumes that nodes in the network only know their immediate neighborhoods and an upper bound on the network's diameter. Clock-synchronization messages are only sent as part of the communication, assumed reasonably frequent, that already takes place among nodes. The algorithm has the gradient property of [2], achieving an O(1) worst-case skew between the logical clocks of neighbors. As in the case of [3,8], the algorithm's actions are such that no constant lower bound exists on the rate at which logical clocks progress in time, and for this reason the lower bound of [2,5] that forbids constant skew between neighbors does not apply

Rates for the reactions antiproton-proton --> pi phi and gamma phi

We study antiproton-proton annihilation at rest into $\pi\phi$ and $\gamma\phi$. Rescattering by $\overline{K^*}K+K^*\overline{K}$ and $\rho^{+}\rho^{-}$ for $\overline{p}p\rightarrow\pi\phi$ states is sizable, of order $(0.90\, {\rm to}\,2.6)\times 10^{-4}$ in the branching ratio, but smaller than experiment. For $\overline{p}p\rightarrow\gamma\phi$ the rescattering contributions are negligible, but the $\gamma\phi$ channel is well explained by a $\rho\phi$ intermediate state combined with vector meson dominance.Comment: 12 pages, plain latex, 2 postscript figures available upon request, PSI-PR-93-2

Placebos in der Psychotherapieforschung – eine systematische Analyse am Beispiel der systematischen Desensibilisierung

Hintergrund: Die Voraussetzungen der randomisierten, Placebo-kontrollierten Evaluation - die Ununterscheidbarkeit der Therapiebedingungen für die Patienten und die Verblindung der Therapeuten - sind in der Psychotherapieforschung nicht uneingeschränkt gegeben. Das Ziel dieser qualitativen systematischen Übersichtsarbeit ist es, am Beispiel der systematischen Desensibilisierung (SD) die Vorgehensweisen zur Bestimmung der Behandlungsspezifität zu beschreiben und deren theoretische und praktische Implikationen zu diskutieren. Methodik: Auf der Basis einer systematischen Literaturrecherche in PsycINFO und PubMed für den Zeitraum von 1976-2015 wurden Psychotherapiestudien gesucht, in denen Patienten mit Angstsymptomen einer SD- oder Placebo-Gruppe zugewiesen und verglichen wurden. Nach Extraktion der gewählten Moderator-Variablen konnten 11 Studien eingeschlossen werden. Ergebnisse: Die Ergebnisse zu den spezifischen Effekten der SD waren nicht einheitlich. Eine durchgeführte Moderator-Analyse zeigte, dass der Nachweis spezifischer Effekte von der Glaubwürdigkeit des Placebos und dem dabei erlebten Ausmaß emotionaler Erfahrungen abhängig ist. Schlussfolgerung: Ob ein bestimmtes psychotherapeutisches Verfahren als spezifisch einzustufen ist, hängt von der Operationalisierung der Placebo-Kontrolle ab. Insbesondere bei SD scheint die Einschränkung des zu bearbeitenden Themas und in der Folge die Unterbindung der emotionalen Erfahrung des Patienten innerhalb der Kontrollbedingung eine Voraussetzung dafür zu sein, spezifische Effekte der SD zu finden

Humour support and emotive stance in comments on Korean TV Drama

Viewers on viki.com comment on Korean television drama series while watching: They produce timed comments tied to the timecode of the audiovisual stream. Among the functions these comments have in the community, the expression of emotive stance is central. Importantly, this includes humour support encoded in a variety of linguistic and paralinguistic ways. Our study identifies a range of humour support indicators, which allow us to find comments that are responses to humour. Accordingly, our study explores how commenters make use of the affordances of the Viki timed comment feature to linguistically and paralinguistically encode their humorous reaction to fictional events and to previous comments. We do this both quantitatively e based on a multilingual corpus of all 320,118 timed comments that accompany five Korean dramas we randomly selected (80 episodes in total), and qualitatively based on the in-depth analysis of two episodes. What we contribute is a typology and the distribution of humour support indicators used in a novel genre of technology-mediated communication as well as insights into how the viewing community collectively does humour support. Finally, we also present the semi-automatic detection of humour support as a viable strategy to objectively identify humour-relevant scenes in Korean TV drama

"This is not the place to bother people about BTS": Pseudo-synchronicity and interaction in timed comments by Hallyu fans on the video streaming platform Viki

The community of users on Viki.com, a video streaming platform distributing Asian television to an international audience, use the site to engage with streams of television dramas. Rather than just being passive consumers, viewers interact in a range of different ways, among them the use of Timed Comments (TC). TCs are comments viewers post while viewing dramas. Subsequent viewers can read these comments when streaming the same episode. Users can read and respond to comments by previous viewers as if they were written at the time of watching (similar to Danmaku). Building on our previous work on Viki-TCs, we have framed the community mainly as a harmonious collective engaging with artefacts from a different cultural and linguistic context. In this study, we focus on the creation of pseudo-synchronicity by looking at interactivity between TC writers and in particular on those TCs that construct conflict. Our corpus consists of 320,000 multilingual, but predominantly English comments. We make use of an exhaustively annotated sample of 8,930 comments to extract and formalize patterns of implicit and explicit interaction and locate them in the larger corpus using corpus linguistic methods. Special attention is given to conflictual interaction in connection with plot spoilers, judgments on co-viewers' analytic and experiential skills and inappropriate language usage, negative comments on actor appearance, commenters using the space for fan interaction outside of the drama-scope and the technical use of the platform. These conflictual interactions often function as negotiations of the platform norms, socialize viewers into how the space works and can thus also be linked to community building. Our study contributes to understanding better how online fan community norms are built and behavior is sanctioned or (implicitly) condoned through interaction. In this way we contribute both to the study of interaction in a context that works online and asynchronously and to the study of online fan communities

Translating the other: Communal TV watching of Korean TV drama

Our research is situated in the field of the pragmatics of fiction (Locher and Jucker 2017; Messerli 2017), and explores a website that makes Asian drama series and movies accessible to an international audience by means of fan generated subtitles in over 150 languages ( www.viki.com ; Dwyer 2012, 2017). The streaming site offers a social network and participatory element in that it provides viewers with different possibilities of participation. Next to producing subtitles in teams, members can comment on episodes and actors, rate shows, produce their own videos, write to each other, etc. This paper explores the possibility of viewers commenting on the episode while it is being watched as a dynamic form of active reception. These comments are time-aligned with the video, which acts as the pivot of the interaction. Viewers can read other fans' comments, and can contribute their own comments and thus their own voice to this additional communal layer of drama series reception. Despite the fact that viewers typically view episodes and read/write comments asynchronously, a simultaneous viewing experience among an international community is created. We present a case study of the viewing of the first episode of two series and show how the commentators negotiate a number of issues, which include expectations about genre, character development, intertextuality and culture. We demonstrate that engaging with the video through written comments, engaging with each other in these comments and participating cross-linguistically are highly interactive, pragmatic achievements between different modes of communication of which the video itself is the starting point. Crucially, the timed comments also contribute to translating and making sense of the cultural 'other' as rendered in the videos. This is particularly the case in the comments on culture triggered by the video but also transpires in dialogues between the members

Contrastive analysis of English fan and professional subtitles of Korean TV Drama

We compare fan subtitles and subtitles produced by professionals in order to detect what concepts each of them foreground, and how they differ in register and in translation strategy. Differences are systematically explored with the help of corpus-assisted discourse analysis to contrast two sets of English subtitles from 26 Korean dramas and 451 episodes - fan subtitles from Viki and professional subtitles from Netflix. Results reveal that professional translators show more target text orientation, whereas fan translators position themselves and their readers as expert members of their community, aiming for access to the source text. We find no clear difference in register, but professional subtitles are more concise, whereas Viki subtitles are longer and employ, e.g., hedges and disfluency markers

Coherent Pion Radiation From Nucleon Antinucleon Annihilation

A unified picture of nucleon antinucleon annihilation into pions emerges from a classical description of the pion wave produced in annihilation and the subsequent quantization of that wave as a coherent state. When the constraints of energy-momentum and iso-spin conservation are imposed on the coherent state, the pion number distribution and charge ratios are found to be in excellent agreement with experiment.Comment: LaTex, 8 text pages, 1 PostScript figure, PSI-PR-93-2
