Does money matter in the ECB strategy?

Helge Berger, Jakob De Haan & Jan-Egbert Sturm
We examine the role of money in the policies of the ECB, using introductory statements of the ECB President at the monthly press conferences during 1999-2004. Over time, the relative amount of words devoted to the monetary analysis has decreased. Our analysis of indicators of the monetary policy stance suggests that developments in the monetary sector, while somewhat more important in the later half of the sample, only played a minor role most of the...

Syntax und Valenz

Timm Lichte
Diese Arbeit untersucht das Verhältnis zwischen Syntaxmodell und lexikalischen Valenzeigenschaften anhand der Familie der Baumadjunktionsgrammatiken (TAG) und anhand der Phänomenbereiche Kohärenz und Ellipse. Wie die meisten prominenten Syntaxmodelle betreibt TAG eine Amalgamierung von Syntax und Valenz, die oft zu Realisierungsidealisierungen führt. Es wird jedoch gezeigt,dass TAG dabei gewisse Realisierungsidealisierungen vermeidet und Diskontinuität bei Kohärenz direkt repräsentieren kann;dass TAG trotzdem und trotz der im Vergleich zu GB, LFG und HPSG wesentlich eingeschränkten Ausdrucksstärke zu einer linguistisch...

Analyzing patterns of economic growth

Monika Kerekes
The growth experience of virtually all but the very rich countries is best explained as a combination of high and low growth episodes. Therefore, there is a need to under- stand the sources of growth during high and low growth regimes and in particular the influences as growth regimes change. This paper approaches the issue by combining the derivation of structural breaks in economic growth with nonparametric growth accounting that enables the decomposition of productivity...

Somali gender polarity revisited

Morgan Nilsson
Diversity in African Languages contains a selection of revised papers from the 46th Annual Conference on African Linguistics, held at the University of Oregon. Most chapters focus on single languages, addressing diverse aspects of their phonology, morphology, semantics, syntax, information structure, or historical development. These chapters represent nine different genera: Mande, Gur, Kwa, Edoid, Bantu, Nilotic, Gumuzic, Cushitic, and Omotic. Other chapters investigate a mix of languages and families, moving from typological issues to sociolinguistic...

Elevated Gestational IL-13 During Fetal Development Is Associated With Hyperactivity and Inattention in Eight-Year-Old Children

Loreen Thürmann, Gunda Herberth, Ulrike Rolle-Kampczyk, Stefan Röder, Michael Borte, Martin Von Bergen, Irina Lehmann & Saskia Trump
Maternal immune activation (MIA) during fetal development leads to behavioral and psychological disorders in the offspring. Concomitantly, insufficient supply of polyunsaturated fatty acids (PUFAs) is suspected to contribute to early neuronal maldevelopment due to the immune modulatory capabilities of PUFAs. However, human data are missing considering both of these aspects and their impact on children's behavioral outcomes. In line, this study aimed to elucidate the influence of gestational cytokines and PUFA-containing lipids during late pregnancy...

Profiles of physical activity biographies in relation to life and aging satisfaction in older adults: longitudinal findings

Paul Gellert, Julian Wienert, Jochen P. Ziegelmann & Adelheid Kuhlmey
Background: While there is substantial evidence on the relationship between life satisfaction and present physical activity (PA), less is known about which specific PA biographies are associated with a high quality of life and aging satisfaction. Our objective was to identify classes of PA biographies that may be associated with life and aging satisfaction. Methods: In this longitudinal study, PA biographies were assessed retrospectively as a baseline, followed by assessments of life and aging satisfaction...

Spectral CT in patients with acute thoracoabdominal bleeding–a safe technique to improve diagnostic confidence and reduce dose?

Johannes Kahn, Uli Fehrenbach, Georg Böning, Felix Feldhaus, Martin Maurer, Diane Renz & Florian Streitparth
Computed tomography (CT) protocols for the detection of bleeding sources often include unenhanced CT series to distinguish contrast agent extravasation from calcification. This study evaluates whether virtual non-contrast images (VNC) can safely replace real non-contrast images (RNC) in the search for acute thoracoabdominal bleeding and whether monoenergetic imaging can improve the detection of the bleeding source. The 32 patients with active bleeding in spectral CT angiography (SCT) were retrospectively analyzed. RNC and SCT series were...

Cognitive Impairment in Neuromyelitis Optica Spectrum Disorders: A Review of Clinical and Neuroradiological Features

Frederike Cosima Oertel, Jana Schließeit, Alexander U. Brandt & Friedemann Paul
Neuromyelitis optica spectrum disorders (NMOSD) are mostly relapsing autoimmune inflammatory disorders of the central nervous system (CNS) with optic neuritis, myelitis, and brainstem syndromes as clinical hallmarks. With a reported prevalence of up to 70%, cognitive impairment is frequent, but often unrecognized and an insufficiently treated burden of the disease. The most common cognitive dysfunctions are decline in attention andmemory performance.Magnetic resonance imaging can be used to access structural correlates of neuropsychological disorders. Cognitive impairment...

Inducible Defenses Stay Up Late: Temporal Patterns of Immune Gene Expression in Tenebrio molitor

Paul R. Johnston, Olga Makarova & Jens Rolff
The course of microbial infection in insects is shaped by a two-stage process of immune defense. Constitutive defenses, such as engulfment and melanization, act immediately and are followed by inducible defenses, archetypically the production of antimicrobial peptides, which eliminate or suppress the remaining microbes. By applying RNAseq across a 7-day time course, we sought to characterize the long-lasting immune response to bacterial challenge in the mealworm beetle Tenebrio molitor, a model for the biochemistry of...

The PD-1/PD-L1 Axis and Virus Infections: A Delicate Balance

Günther Schönrich & Martin J. Raftery
Programmed cell death protein (PD-1) and its ligands play a fundamental role in the evasion of tumor cells from antitumor immunity. Less well appreciated is the fact that the PD-1/PD-L1 axis also regulates antiviral immune responses and is therefore modulated by a number of viruses. Upregulation of PD-1 and its ligands PD-L1 and PD-L2 is observed during acute virus infection and after infection with persistent viruses including important human pathogens such as human immunodeficiency virus...

Intraspecific predation in immature Coenagrion puella (L.): a switch in food selection? (Zygoptera: Coenagrionidae)

Jens Rolff & C. Kröger
Observations on cannibalism in outdoor insectaries are presented. The behavioural interactions are described. Cannibalism (in both sexes) occurred only during periods of cold weather. It is hypothesised that intraspecific predation is a switch in food selection due to bad weather conditions.

Real world experience of patients with amyotrophic lateral sclerosis (ALS) in the treatment of spasticity using tetrahydrocannabinol:cannabidiol (THC:CBD)

Thomas Meyer, Andreas Funke, Christoph Münch, Dagmar Kettemann, André Maier, Bertram Walter, Annett Thomas & Susanne Spittel
Background: Treatment of spasticity poses a major challenge in amyotrophic lateral sclerosis (ALS) patient management. Delta-9-tetrahydrocannabinol (THC):cannabidiol (CBD) oromucosal spray (THC:CBD), approved for the treatment of spasticity in multiple sclerosis, serves as a complementary off-label treatment option in ALS-related spasticity. However, few structured data are available on THC:CBD in the treatment of spasticity in ALS. Method: A retrospective mono-centric cohort study was realised in 32 patients that meet the following criteria: 1) diagnosis of ALS,...

German male income volatility 1984 to 2008

Charlotte Bartels & Timm Bönke
Deploying data from the German Socio-Economic Panel (GSOEP) we analyze the variability of individual earnings and equivalent household income. Permanent and transitory variances of male income over the period 1984-2008 are estimated for Old German Laender in order to determine their importance to income dynamics. To uncover the role of the welfare state in smoothening earnings shocks we compute different income concepts reaching from gross earnings to net equivalent household income. We find evidence that...

Angebot und Inanspruchnahme von Sporttherapie in stationär-psychiatrischen Einrichtungen in Deutschland

Katharina Brehm
Introduction: The positive effect of exercise on general health has been widely known for years. Increasing evidence suggests effectiveness in the treatment of mental disorders as well, some studies even indicating equal effect sizes of exercise when compared to standard treatment. Following these findings, exercise as an additional therapy is recommended by national and international guidelines for the treatment of mental disorders . However, it remains unclear how well exercise is implemented in daily clinical...

Untersuchung des Einflusses von Harnstoff, Glukose, Kreatinin und Guanidinbernsteinsäure auf Gerinnungsvorgänge in vitro mittels ROTEM und PFA-100

Michael Huber
The bleeding tendency of uraemic patients, which was first described by MORGAGNI in 1764, is nowadays essentially being considered as a thrombocytopathy conditioned by multiple factors, even if other causes such as renal anemia further increase this bleeding tendency . This is based on numerous studies involving animal and in-vitro testing that have been conducted since the 1950s. Only a very few studies have examined the structure of the fibrin clots which are formed in...

Die Rolle des ephrinB2-EphB4 Signalweges bei der Vermittlung vaskulärer Resistenzmechanismen unter antiangiogener Therapie

Christian Uhl
Introduction Glioblastoma multiforme is the most frequent malignant brain tumor. Despite all medical efforts, the 5 year-survival rate is still only 5%. Antiangiogenic therapies, which primarily target the vascular endothelial growth factor (VEGF), have demonstrated a positive impact on other tumor entities, yet they have not improved the overall survival of patients with glioblastoma multiforme so far. Increased activation of parallel angiogenic pathways, such as the receptor tyrosine kinase EphB4 and its ligand ephrinB2, probably...

The Alor-Pantar languages

(:Unkn) Unknown
The Alor-Pantar family constitutes the westernmost outlier group of Papuan (Non-Austronesian) languages. Its twenty or so languages are spoken on the islands of Alor and Pantar, located just north of Timor, in eastern Indonesia. Together with the Papuan languages of Timor, they make up the Timor-Alor- Pantar family. The languages average 5,000 speakers and are under pressure from the local Malay variety as well as the national language, Indonesian. This volume studies the internal and...

Berlin Climate Record - Inner City - 1766-1934

Christopher Kadow, Bianca Wentzel, Ilona Jaekel, Marcus Barlow & Ulrich Cubasch
Berlin (Germany) has one of the longest climate records in the world (Cubasch and Kadow, 2011). In the 17th century mainly the family of the astronomer Kirch started measuring the temperature and wrote down general weather patterns. In the beginning of the 18th century the measurements became more regular including multiple measures per day. Over time, more inner city stations appeared but also disappeared. Therefore, this Berlin Climate Record is a moving station, but representable...

Laser control and electron dynamics of ultrafast energy transfer processes in quantum dots

Anika Haller
The inter-Coulombic decay (ICD) is an ultrafast energy transfer process between an electronically excited species that relaxes and a neighboring one that is simultaneously ionized. This Coulomb interaction mediated mechanism has been recently discovered likewise in atomic, molecular, biological, and nanostructured systems, whereas the latter ones require more sophisticated theoretical interpretations as well as an experimental proof. In this thesis, ICD is theoretically studied focusing on the role of the efficient decay of a two-electron...
