Transforming constituent-based annotation into dependency-based annotation has been shown to work for different treebanks and annotation schemes (e.g. Lin (1995) has transformed the Penn treebank, and Kübler and Telljohann (2002) the Tübinger Baumbank des Deutschen (TüBa-D/Z)). These ventures are usually triggered by the conflict between theory-neutral annotation, that targets most needs of a wider audience, and theory-specific annotation, that provides more fine-grained information for a smaller audience. As a compromise, it has been pointed out that treebanks can be designed to support more than one theory from the start (Nivre, 2003). We argue that information can also be added to an existing annotation scheme so that it supports additional theory-specific annotations. We also argue that such a transformation is useful for improving and extending the original annotation scheme with respect to both ambiguous annotation and annotation errors. We show this by analysing problems that arise when generating dependency information from the constituent-based TüBa-D/Z.
The avifauna of the island of Flores and its satellite islands from Komodo to Alor is reviewed, combining historical data with recent observations. Recent surveys have added substantially to the data base, especially of the resident forest species, and endangered and endemic taxa, as well as adding a number of migrant and maritime species to the island list. Of particular interest are the rare forest endemics Wallace's Hanging-parrot Loriculus flosculus, the almost unknown Flores Scopsowl Otus alfredi, Flores Monarch Monarcha sacerdotum and Flores Crow Corvus florensis. An appeal is made for further surveys over the eastern part of the island and the eastern island chain.
The first step in methanol metabolism in methylotrophic yeasts, the oxidation of methanol and higher alcohols with molecular oxygen to formaldehyde and hydrogen peroxide, is catalysed by alcohol oxidase (AOX), a 600-kDa homo-octamer containing eight FAD cofactors. When these yeasts are grown with methanol as the carbon source, AOX forms large crystalline arrays in peroxisomes. We determined the structure of AOX by cryo-electron microscopy at a resolution of 3.4 Å. All residues of the 662-amino acid polypeptide as well as the FAD are well resolved. AOX shows high structural homology to other members of the GMC family of oxidoreductases, which share a conserved FAD binding domain, but have different substrate specificities. The preference of AOX for small alcohols is explained by the presence of conserved bulky aromatic residues near the active site. Compared to the other GMC enzymes, AOX contains a large number of amino acid inserts, the longest being 75 residues. These segments are found at the periphery of the monomer and make extensive inter-subunit contacts which are responsible for the very stable octamer. A short surface helix forms contacts between two octamers, explaining the tendency of AOX to form crystals in the peroxisomes.
Ein Vordenker, der in der internationalen Diskussion um « cultural translation » so gut wie nie diskutiert wird, ist Antonio Gramsci. Der Philosoph aus Sardinien, von Kindes Tagen an in Zweisprachigkeit (Sardisch-Italienisch) geübt, hat ein feines Sensorium für kulturelle Differenzen ausgebildet. In seinen Gefängnisjahren übersetzt er – als intellektuelles Training – aus dem Russischen und dem Deutschen ins Italienische, und in den Gefängnisheften setzt er sich wiederholt mit dem Begriff der traducibilità (Übersetzbarkeit) auseinander: Übersetzbarkeit von Sprachen, aber auch von Kulturen. Der Artikel geht den Linien nach, die von Gramscis Überlegungen zu der aktuellen Diskussion gezogen werden können, und diskutiert am Ende vergleichend die Positionen Homi K. Bhabhas und Gayatri Spivaks.
Body image dissatisfaction is a serious, global problem that negatively affects life satisfaction. Several claims have been made about the possible psychological benefits of naturist activities, but very little empirical research has investigated these benefits or any plausible explanations for them. In three studies—one large-scale, cross-sectional study (n = 849), and 2 prospective studies (n = 24, n = 100) this research developed and applied knowledge about the possible benefits of naturist activities. It was found that more participation in naturist activities predicted greater life satisfaction—a relationship that was mediated by more positive body image, and higher self-esteem (Study 1). Applying these findings, it was found that participation in actual naturist activities led to an increase in life satisfaction, an effect that was also mediated by improvements in body image and self-esteem (Studies 2 and 3). The potential benefits of naturism are discussed, as well as possible future research, and implications for the use of naturist activities.
Six new species ofTrichoptera are described and figured, belonging to the families Goeridae and Leptoceridae. The goerid species are Goera baishanzuensis new species and Goera recta new species. The leptocerid species are Setodes chlorinus new species, Ceraclea (Athripsodina) semicircularis new species, Ceraclea (Athripsodina) brachyclada new species, and Ceraclea (Athripsodina) vaciva new species (Leptoceridae).
The impact of naval sonar on beaked whales is of increasing concern. In recent years the presence of gas and fat embolism consistent with decompression sickness (DCS) has been reported through postmortem analyses on beaked whales that stranded in connection with naval sonar exercises. In the present study, we use basic principles of diving physiology to model nitrogen tension and bubble growth in several tissue compartments during normal div ng behavior and for several hypothetical dive profiles to assess the risk of DCS. Assuming that normal diving does not cause nitrogen tensions in excess of those shown to be safe for odontocetes, the modeling indicates that repetitive shallow dives, perhaps as a consequence of an extended avoidance reaction to sonar sound, can indeed pose a risk for DCS and that this risk should increase with the duration of the response. If the model is correct, then limiting the duration of sonar exposure to minimize the duration of any avoidance reaction therefore has the potential to reduce the risk of DCS.
