    Focus Particles and Extraction – An Experimental Investigation of German and English Focus Particles in Constructions with Leftward Association

    Get PDF
    In my dissertation on leftward association of English and German focus particles, I investigate the following overall research questions: How strong is the c-command relation between focus particles and their associated focus? Is their relation fixed or are there factors which can license leftward association? In my study, I focus on the English particles "only" and "even" and the corresponding German particles "nur" and "sogar". These particles preferably c-command their associated focus constituent (as in "Only SAM will eat chocolate). It is controversial in the literature how strong this c-command relation is and whether leftward association of these particles is acceptable (as in "SAM will only eat chocolate"). To my knowledge, my study provides the first experimental investigation dealing with this phenomenon. In the analysis of examples from everyday language and in various acceptability judgment studies, I identified the following factors which license leftward association of the German particles under consideration: (i) prosody, (ii) speaker evaluation, and (iii) special emphasis. I conclude that the c-command relation between focus particles and their associated focus is strong but not fixed in such a way that leftward association is impossible, as there are factors which improve and license this construction. Moreover, German examples I collected from spontaneous speech provide evidence that leftward association of the German particles under consideration occurs in spoken language. I base my explanations of the data on theories dealing with emphatic syntactic constructions and on theories dealing with salience and cognitive prominence. I propose an account which combines information structure, pragmatics, and processing

    Get PDF
    Die Außer-Haus-Verpflegung von Kindern und Jugendlichen ist nachwie vor ein aktuelles Thema. Aus diesem Grund wurden im Rahmen des Bundesprogramms Ökologischer Landbau Modellprojekte zu diesem Thema eingeworben. Das Ziel war, mehr Bio in der Schulverpflegung und in Kindertagesstätten zu etablieren. Aus der Vielzahl von Vorschlägen wurden vier Modellprojekte ausgewählt, die die Einführung von Biokost in Schulen und Kindertagesstätten mit allen möglichen Fragen und Stolpersteinen aus verschiedenen Blickwinkeln beleuchten. Als Projektstandorte wurden Hamburg, Berlin, Rhein-Main-Gebiet und der Schwalm-Eder-Kreis in Nordhessen ausgewählt. Die Ergebnisse aus den Projekten zeigen, wie vielseitig die Problematik, aber auch die Herangehensweise zur Lösung der Probleme sein kann

    In-vivo multilaboratory investigation of the optical properties of the human head

    Get PDF
    The in-vivo optical properties of the human head are investigated in the 600–1100 nm range on different subjects using continuous wave and time domain diffuse optical spectroscopy. The work was performed in collaboration with different research groups and the different techniques were applied to the same subject. Data analysis was carried out using homogeneous and layered models and final results were also confirmed by Monte Carlo simulations. The depth sensitivity of each technique was investigated and related to the probed region of the cerebral tissue. This work, based on different validated instruments, is a contribution to fill the existing gap between the present knowledge and the actual in-vivo values of the head optical properties

    Altres ajuts: JF reports grants from Instituto de Salud Carlos III, grants from Fundació Marató TV3, grants from NIH, grants from Departament de Salut de la Generalitat de Catalunya.To investigate the frequency, time-course and predictors of intracerebral haemorrhage (ICH), recurrent convexity subarachnoid haemorrhage (cSAH), and ischemic stroke after cSAH associated with cerebral amyloid angiopathy (CAA). We performed a systematic review and international individual patient-data pooled analysis in patients with cSAH associated with probable or possible CAA diagnosed on baseline MRI using the modified Boston criteria. We used Cox proportional hazards models with a frailty term to account for between-cohort differences. We included 190 patients (mean age 74.5 years; 45.3% female) from 13 centers with 385 patient-years of follow-up (median 1.4 years). The risks of each outcome (per patient-year) were: ICH 13.2% (95% CI 9.9-17.4); recurrent cSAH 11.1% (95% CI 7.9-15.2); combined ICH, cSAH, or both 21.4% (95% CI 16.7-26.9), ischemic stroke 5.1% (95% CI 3.1-8) and death 8.3% (95% CI 5.6-11.8). In multivariable models, there is evidence that patients with probable CAA (compared to possible CAA) had a higher risk of ICH (HR 8.45, 95% CI 1.13-75.5, p = 0.02) and cSAH (HR 3.66, 95% CI 0.84-15.9, p = 0.08) but not ischemic stroke (HR 0.56, 95% CI 0.17-1.82, p = 0.33) or mortality (HR 0.54, 95% CI 0.16-1.78, p = 0.31). Patients with cSAH associated with probable or possible CAA have high risk of future ICH and recurrent cSAH. Convexity SAH associated with probable (vs possible) CAA is associated with increased risk of ICH, and cSAH but not ischemic stroke. Our data provide precise risk estimates for key vascular events after cSAH associated with CAA which can inform management decisions.

    Shades of empire: police photography in German South-West Africa

    Get PDF
    This article looks at a photographic album produced by the German police in colonial Namibia just before World War I. Late 19th- and early 20th-century police photography has often been interpreted as a form of visual production that epitomized power and regimes of surveillance imposed by the state apparatuses on the poor, the criminal and the Other. On the other hand police and prison institutions became favored sites where photography could be put at the service of the emergent sciences of the human body—physiognomy, anthropometry and anthropology. While the conjuncture of institutionalized colonial state power and the production of scientific knowledge remain important for this Namibian case study, the article explores a slightly different set of questions. Echoing recent scholarship on visuality and materiality the photographic album is treated as an archival object and visual narrative that was at the same time constituted by and constitutive of material and discursive practices within early 20th-century police and prison institutions in the German colony. By shifting attention away from image content and visual codification alone toward the question of visual practice the article traces the ways in which the photo album, with its ambivalent, unstable and uncontained narrative, became historically active and meaningful. Therein the photographs were less informed by an abstract theory of anthropological and racial classification but rather entrenched with historically contingent processes of colonial state constitution, socioeconomic and racial stratification, and the institutional integration of photography as a medium and a technology into colonial policing. The photo album provides a textured sense of how fragmented and contested these processes remained throughout the German colonial period, but also how photography could offer a means of transcending the limits and frailties brought by the realities on the ground.International Bibliography of Social Science

    PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar

    Full text link
    (Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs are found at 3.3, 6.2, 7.7, 8.6, and 11.2 μ\mum. The most sensitive, highest-resolution infrared spectral imaging data ever taken of the prototypical PDR, the Orion Bar, have been captured by JWST. We provide an inventory of the AIBs found in the Orion Bar, along with mid-IR template spectra from five distinct regions in the Bar: the molecular PDR, the atomic PDR, and the HII region. We use JWST NIRSpec IFU and MIRI MRS observations of the Orion Bar from the JWST Early Release Science Program, PDRs4All (ID: 1288). We extract five template spectra to represent the morphology and environment of the Orion Bar PDR. The superb sensitivity and the spectral and spatial resolution of these JWST observations reveal many details of the AIB emission and enable an improved characterization of their detailed profile shapes and sub-components. While the spectra are dominated by the well-known AIBs at 3.3, 6.2, 7.7, 8.6, 11.2, and 12.7 μ\mum, a wealth of weaker features and sub-components are present. We report trends in the widths and relative strengths of AIBs across the five template spectra. These trends yield valuable insight into the photochemical evolution of PAHs, such as the evolution responsible for the shift of 11.2 μ\mum AIB emission from class B11.2_{11.2} in the molecular PDR to class A11.2_{11.2} in the PDR surface layers. This photochemical evolution is driven by the increased importance of FUV processing in the PDR surface layers, resulting in a "weeding out" of the weakest links of the PAH family in these layers. For now, these JWST observations are consistent with a model in which the underlying PAH family is composed of a few species: the so-called 'grandPAHs'.Comment: 25 pages, 10 figures, to appear in A&

    PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula

    Full text link
    The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypical highly irradiated dense photo-dissociation region (PDR). We investigate the fundamental interaction of far-ultraviolet photons with molecular clouds. The transitions across the ionization front (IF), dissociation front (DF), and the molecular cloud are studied at high-angular resolution. These transitions are relevant to understanding the effects of radiative feedback from massive stars and the dominant physical and chemical processes that lead to the IR emission that JWST will detect in many Galactic and extragalactic environments. Due to the proximity of the Orion Nebula and the unprecedented angular resolution of JWST, these data reveal that the molecular cloud borders are hyper structured at small angular scales of 0.1-1" (0.0002-0.002 pc or 40-400 au at 414 pc). A diverse set of features are observed such as ridges, waves, globules and photoevaporated protoplanetary disks. At the PDR atomic to molecular transition, several bright features are detected that are associated with the highly irradiated surroundings of the dense molecular condensations and embedded young star. Toward the Orion Bar PDR, a highly sculpted interface is detected with sharp edges and density increases near the IF and DF. This was predicted by previous modeling studies, but the fronts were unresolved in most tracers. A complex, structured, and folded DF surface was traced by the H2 lines. This dataset was used to revisit the commonly adopted 2D PDR structure of the Orion Bar. JWST provides us with a complete view of the PDR, all the way from the PDR edge to the substructured dense region, and this allowed us to determine, in detail, where the emission of the atomic and molecular lines, aromatic bands, and dust originate

    Deconvolution of complex G protein–coupled receptor signaling in live cells using dynamic mass redistribution measurements

    Label-free biosensor technology based on dynamic mass redistribution (DMR) of cellular constituents promises to translate GPCR signaling into complex optical 'fingerprints' in real time in living cells. Here we present a strategy to map cellular mechanisms that define label-free responses, and we compare DMR technology with traditional second-messenger assays that are currently the state of the art in GPCR drug discovery. The holistic nature of DMR measurements enabled us to (i) probe GPCR functionality along all four G-protein signaling pathways, something presently beyond reach of most other assay platforms; (ii) dissect complex GPCR signaling patterns even in primary human cells with unprecedented accuracy; (iii) define heterotrimeric G proteins as triggers for the complex optical fingerprints; and (iv) disclose previously undetected features of GPCR behavior. Our results suggest that DMR technology will have a substantial impact on systems biology and systems pharmacology as well as for the discovery of drugs with novel mechanisms

    Freezing. Theoretical approaches and empirical domains

    No full text
    Displacement is a fundamental property of human language, and the restrictions on displacement have been a central concern in generative grammar ever since Ross' (1967) ground-breaking observations of island constraints. While island phenomena have been investigated in detail from various perspectives, a different domain, the domain of Freezing, originally defined in terms of non-base structures, has received far less attention. This volume brings together papers that address the questions of: What are the different concepts of Freezing? Which empirical domains can they explain? Is Freezing a core-syntactic restriction or does information structure, or processing play a role? The collection of papers provides insights into the empirical basis of the Freezing Principle in relation to other restrictions on extraction in order to contribute to a broader understanding of the nature of restrictions on displacement in language. The overall goal of the volume is a reconsideration of Freezing and other (sub-)extraction phenomena, both from a theoretical and empirical perspective, by bringing together contributions from experts in the field to discuss and broaden our knowledge of the empirical range of Freezing phenomena as well as their explanation
