Rechtsextreme Einstellungen, Politikverdrossenheit und die Wahl der Republikaner: zur Rolle von Interaktionseffekten in Logit-Modellen allgemein und in einem speziellen empirischen Fall ; eine Stellungnahme zu Wolfgang Jagodzinski und Markus Klein (1997)
'In der logistischen Regression wird die abhĂ€ngige Variable in unterschiedlichen Transformationen geschĂ€tzt: Logits, Odds und Wahrscheinlichkeiten. Diese sind nicht-linear verknĂŒpft. Vor diesem Hintergrund wird die von Jagodzinski und Klein in der ZA-Information 41 vertretene Auffassung, in logistischen Regressionen wĂŒrde eine bestimmte Art von Interaktionen 'implizit' mitgeschĂ€tzt, diskutiert. Im Zuge der Argumentation wird deutlich, daĂ bei sozialwissenschaftlichen Fragestellungen nicht alle berechenbaren Koeffizienten bzw. Kennzahlen interpretiert werden sollten. Die alternative SchĂ€tzung von Interaktionseffekten mittels CHAID-Segmentationen birgt Probleme. Inhaltlich ergibt die Analyse: Die Neigung zur Wahl der Republikaner im Jahre 1994 lĂ€Ăt sich in erster Linie durch rechtsextreme Einstellungen erklĂ€ren. Ein zusĂ€tzlicher ErklĂ€rungsbeitrag von Politikverdrossenheit ist gering. FĂŒr die Behauptung, nur das Zusammenwirken dieser beiden Variablen bedinge eine Neigung zur Republikanerwahl, finden sich keine Anhaltspunkte.' (Autorenreferat)'In logistic regression analysis the dependent variable is estimated in different transformations: logits, odds and probabilities. The links are non-linear. The interactional consequences of these conditions, as suggested by Jagodzinski and Klein (ZA-Information 41) are discussed. In the course of argumentation it turns out that in social science not all coefficients that can be calculated should also be interpreted. CHAID-Segmentation as an alternative procedure to estimate interactions also involves certain problems. As a substantial finding we show that the tendency to vote for 'Republikaner' in 1994 is mainly explained by right-wing attitudes. The additional explanatory power of political disaffection is only of minor importance. No evidence is found that the exclusive combination of both variables causes the tendency to vote for 'Republikaner'.' (author's abstract)
An in vivo evaluation of Brilliant Blue G in animals and humans
Background/Aims: To evaluate the retinal toxicity of Brilliant Blue G (BBG) following intravitreal injection in rat eyes and examine the biocompatibility and the staining properties in humans.Methods: BBG was injected into the 11 rat eyes to evaluate toxic effects with balanced salt solution (BSS) serving as control. Retinal toxicity was assessed by retinal ganglion cell (RGC) counts and by light microscopy 7 days later. In addition, BBG was applied during vitrectomy for macular hole (MH) (n = 15) or epiretinal membranes (ERM) (n = 3) in a prospective, non-comparative consecutive series of patients. Before and after surgery, all patients underwent a complete clinical examination including measurement of best corrected visual acuity (VA) and intraocular pressure, perimetry, fundus photography and optical coherence tomography. Patients were seen 1 day before surgery and then in approximately four weeks intervals.Results: No significant reduction in RGC numbers and no morphological alterations were noted. A sufficient staining of the internal limiting membrane (ILM) was seen in patients with MH, while the staining pattern in ERM cases was patchy, indicating that parts of the ILM were peeled off along with the ERM in a variable extent. All MHs could be closed successfully. VA improved in 10 eyes (56%; 8/15 MH patients, 2/3 ERM patients), was unchanged in four eyes (22%; all MH patients) and was reduced in four eyes (22%; 3/15 MH, 1/3 ERM). No toxic effects attributable to the dye were noted during patient follow-up. The ultrastructure of tissue harvested during surgery was unremarkable.Conclusion: Brilliant Blue provides a sufficient and selective staining of the ILM. No retinal toxicity or adverse effects related to the dye were observed in animal and human studies. The long-term safety of this novel dye will have to be evaluated in larger patient series and a longer follow-up
Cell composition at the vitreomacular interface in traumatic macular holes
PURPOSE To describe characteristics of the vitreomacular interface (VMI) in traumatic macular holes (TMH) compared to idiopathic macular holes (IMH) using immunofluorescence and electron microscopy, and to correlate with clinical data. METHODS For immunocytochemical and ultrastructural analyses, premacular tissue with internal limiting membrane (ILM) and epiretinal membrane (ERM) was harvested during vitrectomy from 5 eyes with TMH and 5 eyes with IMH. All specimens were processed as flat mounts for phase-contrast microscopy, interference and fluorescence microscopy, and transmission electron microscopy (TEM). Primary antibodies were used against microglial and macroglial cells. Clinical data was retrospectively evaluated. RESULTS Surgically excised premacular tissue of eyes with TMH showed a less pronounced positive immunoreactivity for anti-glutamine synthetase, anti-vimentin and anti-IBA1 compared to eyes with IMH. Cell nuclei staining of the flat-mounted specimens as well as TEM presented a lower cell count in eyes with TMH compared to IMH. All detected cells were found on the vitreal side of the ILM. No collagen fibrils were seen in specimens of TMH. According to patients' age, intraoperative data as well as spectral-domain optical coherence tomography (SD-OCT) analysis revealed an attached posterior vitreous in the majority of TMH cases (60%), whereas all eyes with IMH presented posterior vitreous detachment. CONCLUSION The vitreomacular interface in TMH and IMH shows significant differences. In TMH, glial cells are a rare finding on the vitreal side of the ILM
Impact of Sub-Retinal Fluid on the Long-Term Incidence of Macular Atrophy in Neovascular Age-related Macular Degeneration under Treat & Extend Anti-Vascular Endothelial Growth Factor Inhibitors
Sub-retinal fluid (SRF) has been discussed as a protective factor against macular atrophy in eyes with neovascular age-related macular degeneration (nAMD).To gauge the impact of SRF on macular atrophy, a database of 310 nAMD eyes was screened for eyes manifesting an SRF-only phenotype under treat & extend anti-VEGF treatment, defined as nAMD expressing CNV exudation beyond the three monthly anti-VEGF loading doses by SRF only without any signs of exudative intra-retinal fluid (IRF) for >= 3 years. Incidence of macular atrophy and treatment responses were evaluated on multimodal imaging, including optical coherence tomography (OCT), blue autofluorescence (BAF) and near-infrared (NIR) confocal scanning laser ophthalmoscopy and fluorescence and indocyanine green angiography (FAG/ICGA). In total, 27 eyes (8.7%) of 26 patients with a mean follow-up of 4.2 +/- 0.9 (3-5) years met the inclusion criteria. Mean age was 72 +/- 6 (range: 61-86) years. The SRF only phenotype was seen from baseline in 14 eyes (52%), and in 13 eyes (48%) after a mean 1.0 +/- 1.3 (1-3) injections. In years 1 to 5, mean 7.5, 5.9, 6.1, 6.1 and 7.0 anti-VEGF injections were given (p=0.33). Cumulative macular atrophy incidence was 11.5% at year 1, 15.4% throughout years 2 to 4, and 22.4% at year 5. In conclusion, eyes manifesting activity by SRF only in treat & extend anti-VEGF regimen for nAMD seem to exhibit rather low rates of macular atrophy during long-term follow-up. SRF might be an indicator of a more benign form of nAMD
The Relationship Between Blue-Fundus Autofluorescence and Optical Coherence Tomography in Eyes With Lamellar Macular Holes
PURPOSE. The purpose of this study was to evaluate the relationship between blue-fundus autofluorescence (B-FAF) and optical coherence tomography (OCT) in eyes with lamellar macular holes (LMHs). METHODS. this was a multicenter, observational case series. Ninety-two eyes with LMH associated with the standard epiretinal membrane (ERM) or lamellar hole-associated epiretinal proliferation (LHEP) were evaluated. The eyes must also present an area of increased autofluorescence on B-FAF. RESULTS. The ERM-alone group and the LHEP group differed with respect to the following variables: logarithm of the minimum angle of resolution best-corrected visual acuity (0.13 +/- 0.13 vs. 0.25 +/- 0.17;P < 0.001), central foveal thickness (218.74 +/- 52.4 mu m vs. 187.28 +/- 50.29 mu m;P = 0.008), FAF diameter (400.78 +/- 189.36 mu m vs. 503.37 +/- 214.25 mu m;P = 0.014), outer plexiform layer (OPL) diameter (382.10 +/- 157.34 mu m vs. 550.79 +/- 228.05 mu m;P = 0.0001), and disruption of external limiting membrane and ellipsoid zone, which was noted in only 1 and 3 eyes with ERM alone, respectively, and in 18 and 23 eyes with LHEP, respectively (P < 0.0001 for both observations). No difference was found for diameters measured at the level of the inner limiting membrane and schisis/cavitation. In both the ERM-alone group and the LHEP group, a strong correlation was found between the diameters measured on B-FAF and diameters measured at the OPL level on OCT images (P < 0.0001 for both groups). CONCLUSIONS. In eyes with LMHs, a strong correlation exists between the diameters of the holes measured with B-FAF and those measured at the OPL level with OCT. This may indicate that the loss or displacement of retinal cells containing macular pigment at the OPL level, specifically photoreceptors and/or Muller cells, is involved in this vitreomaculopathy
Arbeitslosigkeit und Nationalsozialismus: eine empirische Analyse des Beitrags der Massenerwerbslosigkeit zu den Wahlerfolgen der NSDAP 1932 und 1933 [1983]
"In social and historical science literature the rise of mass unemployment in Germany until 1933 is often described as causally related to the success of the NSDAP in German elections. Only rarely, however, is the hypothesis concerning the interrelatedness of these two variables adequately founded empirically. An examination of a database covering all districts and administrative reforms instead reveals a negative relation between NSDAP electoral success and figures of unemployment. The analysis of contrast groups shows the variables including the proportion of workers, the proportion of unemployed and the level of urbanization as having a negative effect on the NSDAP's election chances. Seen from their absolute strength, as well as from growth in voters, the NSDAP had more success in regions where the unemployment rate was lower in relation to the average of the Third Reich and vice versa."

Second-moment budgets in cloud topped boundary layers: A large-eddy simulation study
A detailed analysis of second-order moment budgets for cloud topped boundary layers (CTBLs) is performed using high-resolution large-eddy simulation (LES). Two CTBLs are simulatedâone with trade wind shallow cumuli, and the other with nocturnal marine stratocumuli. Approximations to the ensemble-mean budgets of the Reynolds-stress components, of the fluxes of two quasi-conservative scalars, and of the scalar variances and covariance are computed by averaging the LES data over horizontal planes and over several hundred time steps. Importantly, the subgrid scale contributions to the budget terms are accounted for. Analysis of the LES-based second-moment budgets reveals, among other things, a paramount importance of the pressure scrambling terms in the Reynolds-stress and scalar-flux budgets. The pressure-strain correlation tends to evenly redistribute kinetic energy between the components, leading to the growth of horizontal-velocity variances at the expense of the vertical-velocity variance which is produced by buoyancy over most of both CTBLs. The pressure gradient-scalar covariances are the major sink terms in the budgets of scalar fluxes. The third-order transport proves to be of secondary importance in the scalar-flux budgets. However, it plays a key role in maintaining budgets of TKE and of the scalar variances and covariance. Results from the second-moment budget analysis suggest that the accuracy of description of the CTBL structure within the second-order closure framework strongly depends on the fidelity of parameterizations of the pressure scrambling terms in the flux budgets and of the third-order transport terms in the variance budgets.COST/ES/0905DF
The genomic and transcriptional landscape of primary central nervous system lymphoma
Primary lymphomas of the central nervous system (PCNSL) are mainly diffuse large B-cell lymphomas (DLBCLs) confined to the central nervous system (CNS). Molecular drivers of PCNSL have not been fully elucidated. Here, we profile and compare the whole-genome and transcriptome landscape of 51 CNS lymphomas (CNSL) to 39 follicular lymphoma and 36 DLBCL cases outside the CNS. We find recurrent mutations in JAK-STAT, NFkB, and B-cell receptor signaling pathways, including hallmark mutations in MYD88 L265P (67%) and CD79B (63%), and CDKN2A deletions (83%). PCNSLs exhibit significantly more focal deletions of HLA-D (6p21) locus as a potential mechanism of immune evasion. Mutational signatures correlating with DNA replication and mitosis are significantly enriched in PCNSL. TERT gene expression is significantly higher in PCNSL compared to activated B-cell (ABC)-DLBCL. Transcriptome analysis clearly distinguishes PCNSL and systemic DLBCL into distinct molecular subtypes. Epstein-Barr virus (EBV)+ CNSL cases lack recurrent mutational hotspots apart from IG and HLA-DRB loci. We show that PCNSL can be clearly distinguished from DLBCL, having distinct expression profiles, IG expression and translocation patterns, as well as specific combinations of genetic alterations
