The goal of the present study is to supplement inter-cultural comparison of values as a cultural dimension by intra-cultural comparisons, and to go beyond comparisons of single values representing cultural dimensions by studying value patterns on the individual level. Therefore, relationships among general (individualism, collectivism) and domain-specific (family- and child-related) values and the transmission of values in three generations of one family were analyzed. The sample consisted of 100 complete triads of three generations (grandmothers, mothers, and adolescents). The results showed that the individual value orientations of these three generations dif- fered in the expected direction. Individualistic values were more supported by the younger and less by the older generation. While individualism did not show significant relations to other specific values, collectivism was the most powerful dimension to predict family and child-related values. Individual- ism and collectivism clearly turned out as separate dimensions with different functions for the individual value system. The value structure of grandmoth- ers as compared to the younger generations showed more internal consistency. A relative transmission of values was obvious for the adjacent generations. The results are discussed from the perspective of cultural change and stability, and the relation among cultural dimensions and individual value orientations.

PURPOSE To assess intra- and subretinal fluid during the loading phase with intravitreal ranibizumab in exudative age-related macular degeneration and to quantify the accuracy of crosshair scan spectral-domain optical coherence tomography with regard to retinal fluid. METHODS This is a retrospective study of 31 treatment-naive patients who received 3 monthly intravitreal ranibizumab injections. Visual acuity and the presence of retinal fluid were assessed at each visit using volume and crosshair scan protocols. RESULTS Visual acuity improved and central retinal thickness decreased significantly during the loading phase. However, retinal fluid persisted in two thirds of the patients. The accuracy of the crosshair scan to detect fluid was 93%. CONCLUSIONS A substantial proportion of eyes had persistent fluid after 3 months of ranibizumab injections. However, visual improvement was independent of residual fluid. Message: Crosshair scans detect relevant collections of retinal fluid accurately and may be sufficient in daily clinical practice. © 2015 S. Karger AG, Basel.

Self-incompatibility in Brassica is controlled by a single multi-allelic locus (S locus), which contains at least two highly polymorphic genes expressed in the stigma: an S glycoprotein gene (SLG) and an S receptor kinase gene (SRK). The putative ligand-binding domain of SRK exhibits high homology to the secretory protein SLG, and it is believed that SLG and SRK form an active receptor kinase complex with a self-pollen ligand, which leads to the rejection of self-pollen. Here, we report 31 novel SLG sequences of Brassica oleracea and Brassica campestris. Sequence comparisons of a large number of SLG alleles and SLG-related genes revealed the following points. (i) The striking sequence similarity observed in an inter-specific comparison (95.6% identity between SLG14 of B. oleracea and SLG25 of B. campestris in deduced amino acid sequence) suggests that SLG diversification predates speciation. (ii) A perfect match of the sequences in hypervariable regions, which are thought to determine S specificity in an intra-specific comparison (SLG8 and SLG46 of B. campestris) and the observation that the hypervariable regions of SLG and SRK of the same S haplotype were not necessarily highly similar suggests that SLG and SRK bind different sites of the pollen ligand and that they together determine S specificity. (iii) Comparison of the hypervariable regions of SLG alleles suggests that intragenic recombination, together with point mutations, has contributed to the generation of the high level of sequence variation in SLG alleles. Models for the evolution of SLG/SRK are presented.

A study has been performed on the Cretaceous to Early Miocene succession of the Vrancea Nappe (Outer Carpathians, Romania), based on field reconstruction of the stratigraphic record, mineralogical-petrographic and geochemical analyses. Extra-basinal clastic supply and intra-basinal autochthonous deposits have been differentiated, appearing laterally inter-fingered and/or interbedded. The main clastic petrofacies consist of calcarenites, sub-litharenites, quartzarenites, sub-arkoses, and polygenic conglomerates derived from extra-basinal margins. An alternate internal and external provenance of the different supplies is the result of the paleogeographic re-organization of the basin/margins system due to tectonic activation and exhumation of rising areas. The intra-basinal deposits consist of black shales and siliceous sediments (silexites and cherty beds), evidencing major environmental changes in the Moldavidian Basin. Organic-matter-rich black shales were deposited during anoxic episodes related to sediment starvation and high nutrient influx due to paleogeographic isolation of the basin caused by plate drifting. The black shales display relatively high contents in sub-mature to mature, Type II lipidic organic matter (good oil and gas-prone source rocks) constituting a potentially active petroleum system. The intra-basinal siliceous sediments are related to oxic pelagic or hemipelagic environments under tectonic quiescence conditions although its increase in the Oligocene part of the succession can be correlated with volcanic supplies. The integration of all the data in the “progressive reorientation of convergence direction” Carpathian model, and their consideration in the framework of a foreland basin, led to propose some constrains on the paleogeographic-geodynamic evolutionary model of the Moldavidian Basin from the Late Cretaceous to the Burdigalian.
