Impairment in past tense production as well as interaction between tense and aspect have been found in both fluent and non-fluent aphasia (e.g. Dragoy & Bastiaanse, 2013). Inflection has been found to be relatively preserved in semantic dementia (SD) (Thompson et al., 2012). The aims of the present study are a) to compare the morphosyntactic abilities of patients with aphasia and SD in tense and aspect marking and b) to explore the interaction of lexical (+/- telic) and grammatical (perfective/imperfective) aspect in aphasia and SD. A sentence completion task was administered to 30 native speakers of Greek: 10 patients with aphasia (6 anomic, 2 Wernicke and 2 agrammatic), 10 age and education-matched controls, 5 patients with SD and 5 controls. The material consisted of unergative, unaccusative and transitive verbs (12 of each verb class) and the participants had to apply present (imperfective) and past (perfective) tense. Unergative and unaccusative verbs differ in terms of their aspectual properties with the unergative being [-telic], and unaccusative [+telic]. Transitive verbs vary. A principal distinction between the tested conditions was the standard ummarked combination ([+telic] verbs in past perfective and [–telic] verbs in present imperfective) vs. the marked one ([+telic] verbs in present imperfective and [–telic] in past perfective). Both control groups performed at ceiling in all conditions. Aphasic participants were significantly more impaired than the control group in all conditions. SD participants were significantly more impaired than the controls only in the production of present tense (M-W U= 1.5, p= 0.024). There was no difference between past perfective and present imperfective for neither group, but there was an interaction between verb class and tense for the aphasic participants, as performance in unaccusative verbs in past perfective (unmarked condition) was significantly better than in unergatives in past perfective (marked condition) (Z=2.512, p=0.012) but performance in unaccusatives in present imperfective (marked condition) was significantly worse than performance in unergatives in present imperfective (unmarked condition) (Z=2.680, p=0.004). In sum, aphasic participants performed significantly better in the unmarked than in the marked conditions. Such an interaction was not found for the SD group. Aphasic participants performed significantly worse than the SD subjects in past perfective tense (M-W U= 7.5, p=0.029) in total, and the difference was significant only for unaccusative verbs (M-W U= 6.5, p=0.021), although both groups performed very well in this condition. There was no difference in present, neither for each verb class separately nor for the total score. A general past tense deficit cannot be upheld for either group. Rather, SD participants appear relatively impaired in producing present tense. We argue for slight morphosyntactic impairment in SD, although with a different underlying cause than in aphasia. Moreover, our data suggest an effect of aspectual markedness in aphasia but not in SD. We discuss this finding in the light of the different neuropathology of the two populations.
D2.1. provides further elaboration of the original research design and informs about ideas for the final Volume II of bEUcitizen. It is closely connected to task 1 of work package 2: specifying various concrete tasks for the different work packages and formulating overarching questions suitable to provide substantive cohesion and integration of the overall project. The elaboration of 10 crosscutting topics (to become chapters in the “horizontal” book, D2.3.) is a first step towards this goal. Discussing these cross-cutting topics is supposed to feed, infuse and inspire the work done in the different work packages and to build cross-cutting connections between them. Themes 1-10 merge into a valuable overview of the multi-faceted research on (EU) citizenship. They access the main issues of EU-citizenship and citizenship in general from different angles and different disciplines. Taken together these contributions help to identify barriers towards EU citizenship and ways to overcome them. Each Theme formulates questions how it might feed and be fed by further information and findings in the other work packages.
D2.1. is mainly meant for internal use. Its functions are firstly to inform about preliminary ideas, eventual contributions to planned final results and secondly to make out some more of less specific guiding questions that connect the work done by the single researchers in every different work package to the project as a whole. This task implies a normative yardstick, a clear picture of what would be a "good" EU citizenship practice. Elaborating on such a normative yardstick is a meta-topic that cuts across the range of cross-cutting topics presented in this working paper.
Based on a non-rigorous formalism called the “cavity method”, physicists have made intriguing predictions on phase transitions in discrete structures. One of the most remarkable ones is that in problems such as random k-SAT or random graph k-coloring, very shortly before the threshold for the existence of solutions there occurs another phase transition called condensation [Krzakala et al., PNAS 2007]. The existence of this phase transition seems to be intimately related to the difficulty of proving precise results on, e. g., the k-colorability threshold as well as to the performance of message passing algorithms. In random graph k-coloring, there is a precise conjecture as to the location of the condensation phase transition in terms of a distributional fixed point problem. In this paper we prove this conjecture, provided that k exceeds a certain constant k0.
We have studied one-proton-removal reactions of about 500MeV/u 17Ne beams on a carbon target at the R3B/LAND setup at GSI by detecting beam-like 15O-p and determining their relative-energy distribution. We exclusively selected the removal of a 17Ne halo proton, and the Glauber-model analysis of the 16F momentum distribution resulted in an s2 contribution in the 17Ne ground state of about 40%.
Europeana provides a common access point to digital cultural heritage objects across different cultural domains among which the libraries. The recent development of the Europeana Data Model (EDM) provide new ways for libraries to experiment with Linked Data. Indeed the model is designed as a framework reusing various wellknown standards developed in the Semantic Web Community, such as the Resource Description Framework (RDF), the OAI Object Reuse and Exchange (ORE), and Dublin Core namespaces. It provides new opportunities for libraries to provide rich and interlinked metadata to the Europeana aggregation.
However to be able to provide data to Europeana, libraries need to create mappings from the librarystandard to EDM. This step involves decisions based on domainspecific requirements and on the possibilities offered by EDM. The crossdomain nature of EDM limiting in some cases the completeness of the mappings, extension of the model have been proposed to accommodate the library needs.
The "Digitised Manuscripts to Europeana" project (DM2E) has created an extension of EDM to optimise the mappings of librarydata for manuscripts. This extension is in the form of subclasses and subproperties that further specialise EDM concepts and properties. It includes spatial creation and publishing information, specific contributor and publication type properties and more.
Furthermore the granularity of the mapping has been extended to allow references and annotations on page level as required for scholarly work. As part of this project the metadata of the Hebrew Manuscripts as well as of the Medieval Manuscripts presented in the Digital Collections of the Frankfurt University Library have been mapped to this extension. This includes links to the Integrated Authority File (GND) of the German National Library with further links to the Virtual International Authority File (VIAF).
Based on this development a new comprehensive mapping from the digitalisation metadata format METS/MODS to EDM has been established for all materials of the Frankfurt Judaica in "Judaica Europeana ". It demonstrates today’s capabilities of the creation of linked Data structures in Europeana based on library catalogue data and structural data from the digitalisation process.
Cultural heritage reconstructed - Compact Memory and the Frankfurt Digital Judaica Collection
(2014)
Compact Memory, the internet archive of German Jewish periodicals, provides free global internet access to the vast majority of German-Jewish newspapers and periodicals of the 19th and 20th century.
Jewish historical newspapers are the invaluable sources that supply direct and detailed information of the transformation process of Jewry and offer new insights into European Jewish history. The use of these historical sources however is extremely difficult, as complete sets of periodicals are very rarely to be found and they are scattered all over the world in different libraries and archives and in different physical formats (paper, microfilm).
Compact Memory contains the 110 most important Jewish German newspapers and periodicals in Central Europe in the period from 1806-1938, covering the complete range of religious, political, social, cultural and academic aspects of Jewish life. The texts are available partly as full-texts, processed by OCR, partly as graphic documents with corresponding index options. The database offers advanced search options, downloading and printing of articles. Thousands of essays of more than 10.000 individual contributors have been bibliographically indexed.
Compact Memory was established by the Judaica Division of the University Library Frankfurt am Main and in charge today in cooperation with the Aachen Chair of German-Jewish Literary History and the Cologne library Germania Judaica.
Compact Memory is one database within the Digital Collection Judaica which being part of Europeana and other digital portals offers resources for the reconstruction and representation of Jewish cultural heritage.
XIII Nuclei in the Cosmos, 7-11 July, 2014 Debrecen, Hungary.
As an alternative production scenario to the so-called g process, the most abundant p nucleus 92Mo may be produced by a chain of proton-capture reactions in supernovae type Ia. The reactions 90Zr(p,g) and 91Nb(p,g) are the most important reactions in this chain. We have measured the first reaction using high-resolution in-beam g-spectroscopy at HORUS, Cologne, Germany, to contribute to the existing experimental data base. So far, we only investigated the high-energy part of the Gamow window and the analysis is still in progress. We plan to study the second reaction in standard kinematics at the FRANZ facility, Frankfurt, Germany. Current developments at FRANZ will be explained in detail.
We present the results of two-pion production in tagged quasi-free np collisions at a deutron incident beam energy of 1.25 GeV/c measured with the High-Acceptance Di-Electron Spectrometer (HADES) installed at GSI. The specific acceptance of HADES allowed for the first time to obtain high-precision data on π+π− and π−π0 production in np collisions in a region corresponding to large transverse momenta of the secondary particles. The obtained differential cross section data provide strong constraints on the production mechanisms and on the various baryon resonance contributions (∆∆, N(1440), N(1520), ∆(1600)). The invariant mass and angular distributions from the np → npπ+π −and np → ppπ−π0 reactions are compared with different theoretical model predictions.
We have measured the radiative neutron-capture cross section and the total neutron-induced cross section of one of the most important isotopes for the s process, the 25Mg. The measurements have been carried out at the neutron time-of-flight facilities n_TOF at CERN (Switzerland) and GELINA installed at the EC-JRC-IRMM (Belgium). The cross sections as a function of neutron energy have been measured up to approximately 300 keV, covering the energy region of interest to the s process. The data analysis is ongoing and preliminary results show the potential relevance for the s process.
We discuss recent applications of the partonic perturbative QCD based cascade model BAMPS with focus on heavy-ion phenomenology in the hard and soft momentum range. First, the elliptic flow and suppression of charm and bottom quarks are studied at LHC energies. Thereafter, we compare in a detailed study the standard Gunion-Bertsch approximation of the matrix elements for inelastic processes to the exact results in leading order perturbative QCD. Since a disagreement is found, we propose an improved Gunion-Bertsch matrix element, which agrees with the exact result in all phase space regions.
