The correspondence between the terminology used for querying and the one used in content objects to be retrieved, is a crucial prerequisite for effective retrieval technology. However, as terminology is evolving over time, a growing gap opens up between older documents in (long-term) archives and the active language used for querying such archives. Thus, technologies for detecting and systematically handling terminology evolution are required to ensure "semantic" accessibility of (Web) archive content on the long run. As a starting point for dealing with terminology evolution this paper formalizes the problem and discusses issues, first ideas and relevant technologies.
We report progress in our exploration of the finite-temperature phase structure of two-flavour lattice
QCD with twisted-mass Wilson fermions and a tree-level Symanzik-improved gauge action
for a temporal lattice size Nt = 8. Extending our investigations to a wider region of parameter
space we gain a global view of the rich phase structure. We identify the finite temperature transition/
crossover for a non-vanishing twisted-mass parameter in the neighbourhood of the zerotemperature
critical line at sufficiently high b . Our findings are consistent with Creutz’s conjecture
of a conical shape of the finite temperature transition surface. Comparing with NLO lattice
cPT we achieve an improved understanding of this shape.
We perform a detailed study of the adjoint static potential in the pseudoparticle approach, which is a model for SU(2) Yang-Mills theory. We find agreement with the Casimir scaling hypothesis and there is clear evidence for string breaking. At the same time the potential in the fundamental representation is linear for large separations. Our results are in qualitative agreement with results from lattice computations.
We present the status of runs performed in the twisted mass formalism with Nf =2+1+1 flavours of dynamical fermions: a degenerate light doublet and a mass split heavy doublet. The procedure for tuning to maximal twist will be described as well as the current status of the runs using both thin and stout links. Preliminary results for a few observables obtained on ensembles at maximal twist will be given. Finally, a reweighting procedure to tune to maximal twist will be described.

"Ich mag so Wasserpfeifeladen" : the interaction of grammar and information structure in Kiezdeutsch
(2008)
Rawang [...] is a Tibeto-Burman language spoken by people who live in the far north of Kachin State in Myanmar (Burma), particularly along the Mae Hka ('Nmai Hka) and Maeli Hka (Mali Hka) river valleys; population unknown, although Ethnologue gives 100,000. In the past they had been called ‘Nung’, or (mistakenly) ‘Hkanung’, and are considered to be a sub-group of the Kachin by the Myanmar government. They are closely related to people on the other side of the Chinese border in Yunnan classified as either Dulong or Nu (see LaPolla 2001, 2003 on the Dulong language and Sun 1988, Sun & Liu 2005 on the Anong language). In this paper, I will be discussing a particular morphological phenomenon found in Rawang, using data of the Mvtwang (Mvt River) dialect of Rawang, which is considered the most central of those dialects in Myanmar and so has become something of a standard for writing and inter-group communication.
Questions on transitivity
(2008)
This handout (it isn’t a paper) presents phenomena and questions, rather than conclusions, related to the concept of transitivity. The idea is to return to these questions at the end of the Workshop to see if we can have a clearer consensus about the best general analysis of phenomena associated with transitivity. Section 2 presents alternative analyses of transitivity and questions about transitivity in three languages I have worked on. Section 3 discusses a few of the different conceptualisations of transitivity that might be relevant to our thinking about the questions related to these languages or that bring up further questions. Section 4 presents some general questions that might be asked of individual languages.
This paper is more about presenting phenomena and questions related to the concept of transitivity in Tibeto-Burman languages that I hope will stimulate discussion, rather than presenting strong conclusions. Sections 2 and 3 present alternative analyses of transitivity and questions about transitivity in two Tibeto-Burman languages I have worked on. In Section 4 I discuss some general issues about transitivity.
This paper is an inductive look at the constituents found in a randomly selected Tagalog text, Bob Ong’s Alamat ng Gubat (Makati City, MM: Visual Print Enterprises, 2004). The analysis is based on the full text, but we will only be able to go through the first few lines of the text here, which we will do one by one, and discuss the structures found in each line of the text in bullet format after the relevant line. At the end of the paper we will bring up some important questions about the structures found in Tagalog based on this text.
Friedrich Schlegel's lasting contribution to linguistics is usually seen in the impact that his book "Über die Sprache und Weisheit der Indier" from 1808 left on comparative linguistics and on the study of Sanskrit. Schlegel was one of the first European scholars to have studied Sanskrit extensively and he made a number of translations of Sanskrit literature into German which make up one third of "Über die Sprache und Weisheit der Indier". Schlegel's book is widely regarded as a founding document both of comparative linguistics and of indology, a fact which is quite remarkable in light of the development of Schlegel's thought after this text. His interest in Indian studies ceased more or less directly with the publication of this work, while his thoughts on language became more and more suffused by transcendental philosophy.
The study investigates the contribution of tactile and auditory feedback in the adaptation of /s/ towards a palatal prosthesis. Five speakers were recorded via electromagnetic articulography, at first without the prosthesis, then with the prosthesis and auditory feedback masked, and finally with the prosthesis and auditory feedback available. Tongue position, jaw position and acoustic centre of gravity of productions of the sound were measured. The results show that the initial adaptation attempts without auditory feedback are dependent on the prosthesis type and directed towards reaching the original tongue palate contact pattern. Speakers with a prosthesis which retracted the alveolar ridge retracted the tongue. Speakers with a prosthesis which did not change the place of the alveolar ridge did not retract the tongue. All speakers lowered the jaw. In a second adaptation step with auditory feedback available speakers reorganised tongue and jaw movements in order to produce more subtle acoustic characteristics of the sound such as the high amplitude noise which is typical for sibilants.
Several articulatory strategies are available during the production of /u/, all resulting in a similar acoustic output. /u/ has two main constrictions, at the velum and at the lips. A perturbation of either constriction can be compensated at the other one, e.g wider constriction at the velum by more lip protrusion, wider lip opening by more tongue retraction. This study investigates whether speakers use this relation under perturbation. Six speakers were provided with palatal prostheses which were worn for two weeks. Speakers were instructed to make a serious attempt to produce normal speech. Their speech was recorded via EMA and acoustics several times over the adaptation period. Formant values of /u/-productions were measured. Velar constriction width and lip protrusion were estimated. For four speakers a correlation between constriction width and lip protrusion was found. A negative correlation between lip protrusion and F1 or F2 could sometimes be observed, but no correlation occurred between constriction size and either of the formants. The results show that under perturbation speakers use motor equivalent strategies in order to adapt. The correlation between constriction size and lip protrusion is stronger than in studies investigating unperturbed speech. This could be because under perturbation speakers are inclined to try out several strategies in order to reach the acoustic target and the co-variability might thus be greater.
Two hypotheses have been proposed in order to account for velar softening, i.e., a process through which /k/ changes to an affricate. Whereas one hypothesis states that for the process to apply the velar stop has to be realized as an (alveolo) palatal stop (articulation-based hypothesis), the other claims that velar softening is triggered by acoustic similarity between the input and output segments (acoustic equivalence hypothesis). The present paper investigates the acoustic equivalence hypothesis by comparing several acoustic properties of /k/ in various vowel contexts with those of /ts , ts , tc / for three languages differing in stop burst aspiration, i.e., German, Polish and Catalan. Results suggest that the acoustic equivalence hypothesis could account for velar softening in aspirated velar stops but not in unaspirated velar stops. The results also provide an explanation as to why aspirated velar stops are prone to undergo softening more easily when followed by front vocalic segments than in other contexts and positions
This paper shows that several typologically unrelated languages share the tendency to avoid voiced sibilant affricates. This tendency is explained by appealing to the phonetic properties of the sounds, and in particular to their aerodynamic characteristics. On the basis of experimental evidence it is shown that conflicting air pressure requirements for maintaining voicing and frication are responsible for the avoidance of voiced affricates. In particular, the air pressure released from the stop phase of the affricate is too high to maintain voicing, which in consequence leads to a devoicing of the frication part.
Our study is concerned with the identification of ‘difficult’ structure s in the acquisition of a foreign language, which will shed light on theoretical considerations of L2 processing. We argue that – compared to simple vocabulary items or abstract syntactic patterns – structures that contain lexical material as well as categorial variables are especially difficult to acquire. The difficulty level for particular patterns is shown to depend on surface invariability but not on the syntactic categories within which target patterns are embedded. As an example we study the distribution of certain structures which are underused by L2 German learners.
We compare away-side hadron correlations with respect to tagged heavy quark jets computed within a weakly coupled pQCD and a strongly coupled AdS/CFT model. While both models feature similar far zone Mach and diffusion wakes, the far zone stress features are shown to be too weak to survive thermal broadening at hadron freeze-out. Observable away-side conical correlations are dominated by the jet-induced transverse flow in near zone “Neck” region, which differs significantly for both models. Unlike in AdS/CFT, the induced transverse flow in the Neck zone is too weak in pQCD to produce conical correlations after Cooper-Frye freeze-out. The observation of conical correlations violating Mach’s law would favor the strongly-coupled AdS/CFT string drag dynamics, while their absence would favor weakly-coupled pQCD-based hydrodynamics.
This talk concerns the copula system in Buli, a Ghanaian language which has also been attested in Bahia (Rodrigues 1935, Zwernemann 1968). Special focus will be put on the categorization of two copula-reminiscent elements for which I will propose a discoursepragmatic analysis.

Freeze (1992) argued on the basis of data from several different languages that there is a close relationship between existential sentences (stating the existence of an entity) and locative sentences (stating the location of an entity). Freeze (1992) proposes that they are both derived from the same base structure and that the surface differences are rather due to the distinct information structures.This paper argues against this position with the data from Serbian existentials, which show clear syntactic differences from the locatives. Thus, the close relationship between existential and locative sentences that Freeze (1992) observes is conceptual, but not (necessarily) part of the syntax of the language. In order to account for the data, we propose that existential sentences originate from a different syntactic predication structure than the locative ones. The existential meaning arises, as we will show, from the interaction of this predication structure with the structure and meaning of the noun phrase.
Market uptake of pegylated interferons for the treatment of hepatitis C in Europe : meeting abstract
(2008)
Introduction and Objectives Hepatitis C virus (HCV) infection is a leading cause of chronic liver disease with life threatening sequelae such as end-stage liver cirrhosis and liver cancer. It is estimated that the infection annually causes about 86,000 deaths, 1.2 million disability adjusted life years (DALYs), and ¼ of the liver transplants in the WHO European region. Presently, only antiviral drugs can prevent the progression to severe liver disease. Pegylated interferons combined with ribavirin are considered as current state-of-the-art treatment. Objective of this investigation was to assess the market uptake of these drugs across Europe in order to find out whether there is unequal access to optimised therapy. Material and Methods We used IMS launch and sales data (April 2000 to December 2005) for peginterferons and ribavirin for 21 countries of the WHO European region. Market uptake was investigated by comparing the development of country-specific sales rates. For market access analysis, we converted sales figures into numbers of treated patients and related those to country-specific hepatitis C prevalence. To convert sales figures into patient figures, the amount of active pharmaceutical ingredients (API) sold was divided by average total patient doses (ATPD), derived by a probability tree-based calculation algorithm accounting for genotype distribution, early stopping rules, body weight, unscheduled treatment stops and dose reductions Ntotal=APIPegIFNalpha-2a/ATPDPegIFNalpha-2a+APIPegIFN&alpha-2b/ATPDPegIFNalpha-2b For more concise result presentation the 21 included countries were aggregated into four categories: 1. EU founding members (1957): Belgium, France, Germany, Italy and Netherlands; 2. Countries joining EU before 2000: Austria (1995), Denmark (1973), Finland (1995), Greece (1981), Republic of Ireland (1973), Spain (1986), Sweden and UK (1973) 3. Countries joining EU after 2000: Czech Republic (2004), Hungary (2004), Poland (2004) and Romania (2007); 4. EU non-member states: Norway, Russia, Switzerland and Turkey. Results Market launch and market uptake of the investigated drugs differed considerably across countries. The earliest, most rapid and highest increases in sales rates were observed in the EU founding member states, followed by countries that joined the EU before 2000, countries that joined the EU after 2000, and EU non-member states. Most new EU member states showed a noticeable increase in sales after joining the EU. Market access analysis yielded that until end of 2005, about 308 000 patients were treated with peginterferon in the 21 countries. Treatment rates differed across Europe. The number of patients ever treated with peginterferon per 100 prevalent cases ranged from 16 in France to less than one in Romania, Poland, Greece and Russia. Discussion Peginterferon market uptake and prevalence adjusted treatment rates were found to vary considerably across 21 countries in the WHO European region suggesting unequal access to optimised therapy. Poor market access was especially common in low-resource countries. Besides budget restrictions, national surveillance and prevention policy should be considered as explanations for market access variation. Although our results allowed for the ranking of countries in order of market access, no final conclusions on over- or undertreatment can be drawn, because the number of patients who really require antiviral treatment is unknown. Further research based on pan-European decision models is recommended to determine the fraction of not yet successfully treated but treatable patients among those ever diagnosed with HCV. ...
The fear that with the existence of an unconditional basic income sufficient for living many people would cease to engage in a productive life, would only relax, consume and devote to having fun, can be addressed from different perspectives. One of these is the sociology of religion, which allows elaborating the argument that with such a way of life the question about the meaning of life cannot be answered. But this "meaning question", the whole research within the field of the sociology of religion speaks for this, compellingly must be answered by each life praxis. It cannot remain unanswered, as is said already in the Bible: "Man does not live on bread alone, [but on every word that comes from the mouth of God.]" (5. Moses 8.3, Matthew 4.4, Lukas 4.4) The paper examines the reasons of this fact and its consequences in regard to a life with an unconditional basic income sufficient for living.
