The definitive version was published in Journal of Marine Research 68 (2010): 153-188, doi:10.1357/002224010793079013.Marine larval dispersal is affected by hydrodynamic transport and larval behavior, but little is known about how behavior affects large-scale patterns of dispersal and recruitment. Intertidal habitats are characterized by strong and variable turbulence relative to shelf and pelagic waters, so larval responses to turbulence may affect both dispersal and habitat selection. This study combined observations and theoretical approaches to model gastropod larval responses to multiple physical variables in a well-mixed tidal inlet. Physical measurements and larvae were collected in July 2004 in Barnstable Harbor, Massachusetts (USA). Physical measurements were incorporated in an advection-diffusion model where larval vertical velocity is a function of turbulence dissipation rate, temperature, and the temperature gradient. Modeled larval distributions were fitted to observed concentration profiles by maximum likelihood to estimate larval behavioral velocity (swimming or sinking) as a function of environmental conditions. These quantitative behavior estimates were used to test hypotheses about behavioral differences among groups and to assess the relative impact of different cues on overall larval behavior. Larvae of five common gastropod species from different coastal habitats reacted most strongly to turbulence but had genus-specific responses to environmental cues. Larvae of a species from tidal inlets (the mud snail Nassarius obsoletus) had near-zero velocities under calmer conditions and sank in strong turbulence. In contrast, larvae from exposed beach habitats (Crepidula spp. and Anachis spp.) sank in weak turbulence and swam up in strong turbulence, with additional responses to temperature and temperature gradient. Larval responses also differed between small and large size classes and between flood and ebb tides. Behavior of mud snail larvae would contribute to retention inside the inlet and near adult habitats, whereas behavior of beach snail larvae would contribute to rapid export from muddy inlets lacking suitable adult habitats.This work was funded by the Woods Hole Oceanographic Institution (WHOI) Coastal Ocean Institute, the WHOI Rinehart Coastal Research Center, the National Science Foundation (NSF OCE- 0326734), NSF and US Office of Naval Research grants to S.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    No full text
    In der vorliegenden Arbeit werden Aspekte eines integrativen therapeutischen Angebots von Männern für Männer erörtert. Die soziale Konstruktion von Geschlecht wird dargestellt und Wissensstände über Diskurse der Männerbewegung und Männerforschung werden zusammengetragen. Anhand des Konzepts der Lebensbewältigung werden Besonderheiten männlicher Sozialisation erörtert. Für die Schilderung wesentlicher Merkmale männlicher Identität wird das Identitätskonzept der Integrativen Therapie mit den 5 Säulen der Identität verwendet. Nach Überlegungen zu geschlechtsbezogenen Aspekten in einer Therapie wird das Vorarlberger Modell für ein Männerberatungsangebot beschrieben.In this thesis aspects of an integrative therapeutic offering by men for men are discussed. The social construction of gender is shown and knowledge about discourses of men’s movement and men’s studies are compiled. Characteristics of male socialization are discussed by the concept of male coping with life. The identity concept of Integrative Therapy with the 5 columns of identity is used for the description of basic characters of male identity. After considerations about gender concerned aspects in therapy the Vorarlberg concept for men’s counseling is presented.https://www.fpi-publikation.de/polyloge/18-2017-fuchs-b-k-maennertherapie-ueberlegungen-zu-einem-integrativen-therapeutischen-angebot/peerReviewedpublishedVersio

    Planorbis varians Fuchs, 1870 —how to recombine? Planorbis varians Fuchs, 1870 in Fuchs 1870a: 356, pl. 14, figs 1–9. Gyraulus (Gyraulus) varians (Fuchs): Wenz 1923: 1622 (cum syn.). Muellerpalia varians (Fuchs, 1870); Bandel 2010: 104 [not pl. 8, figs 90–94, = Muellerpalia bicincta (Fuchs, 1870)]. Marinescugyra varians (Fuchs, 1870); Bandel 2010: 112, pl. 13, figs 153–158. In his revision about the valvatiform gastropods of the Paratethys realm, Bandel (2010) introduced amongst others the genera Muellerpalia (Hydrobiidae) and Marinescugyra (Planorbidae), based on characteristic protoconch features. One of the discussed species is Planorbis varians Fuchs, 1870 from Rădmăneşti in Romania. On the grounds of different protoconch properties, Bandel assigned specimens, putatively belonging to the same species, to either Muellerpalia (p. 104) or Marinescugyra (p. 112). For the latter, it even constitutes the type species. Hence, Bandel used two different combinations based on the same original combination. From a nomenclatural as well as a taxonomic view this is of course not tenable. It means that either the various specimens belong to two different species or the diagnostic features of the two genera are not meaningful. The associated problems were clear to the author as became evident from personal correspondence: Bandel (pers. comm.) stated the possibility that " Planorbis varians " is actually represented by two species, which would have to be assigned variably to Muellerpalia or Marinescugyra based on their protoconchs. Unfortunately, this discussion is wanting in the paper. However, it turned out that the two combinations indeed refer to different species. The specimens illustrated by Bandel (2010) as " Marinescugyra varians " (pl. 13, figs 153–158) undoubtedly refer to the same species as described by Fuchs (1870a). They correspond in the two strong keels, the intermediate spiral lines, the slightly concave umbilical part, and the weakly stepped funnel-like apical part. In contrast, the individuals depicted as " Muellerpalia varians " (Bandel 2010, pl. 8, figs 90–95) belong to a different species: they have both keels on the umbilical side, apparently lack additional spiral lines, have highly convex whorls, and more distinct growth lines. Direct comparison of the descriptions and illustrations of Fuchs (1870a, b) and Bandel (2010) suggest that Bandel confused several species. Firstly, " Muellerpalia varians " sensu Bandel rather corresponds to " Valvata bicincta Fuchs, 1870 " in Fuchs (1870b) [= Muellerpalia bicincta (Fuchs, 1870)]. Secondly, specimens illustrated as " Muellerpalia bicincta " by Bandel rather resemble " Valvata carinata Fuchs, 1870 " in Fuchs (1870b) [= Muellerpalia carinata (Fuchs, 1870)]. Conversely, Muellerpalia carinata (Fuchs, 1870) sensu Bandel, 2010 may represent Muellerpalia bicincta. The new combinations of both latter taxa with the new genus Muellerpalia still remain valid. The presence of a second, fainter keel on the umbilical side in " Muellerpalia varians " sensu Bandel (2010) [= Muellerpalia bicincta (Fuchs, 1870)], which is not discernible in the original material of Fuchs (1870a), is regarded as intraspecific variability herein, as all other features correspond quite well. Unfortunately, Bandel did not provide an illustration of the apical region, which would show a distinct keel if our determination as M. bicincta is correct. Nevertheless, the endpoint of keel-like structure is visible in the apertural view (Bandel 2010, pl. 8, fig. 94). Even if it might turn out that this tentative placement is wrong, it still remains well separated from Marinescugyra varians. In conclusion, the genus Marinescugyra, with Planorbis varians Fuchs, 1870 as type species, remains valid and the combination Marinescugyra varians (Fuchs, 1870) is the only accepted one. The combination Muellerpalia varians (Fuchs, 1870) is based on a misidentification of the species. We tentatively synonymize this record with Muellerpalia bicincta (Fuchs, 1870).Published as part of Neubauer, Thomas A., Harzhauser, Mathias, Georgopoulou, Elisavet, Mandic, Oleg & Kroh, Andreas, 2014, Replacement names and nomenclatural comments for problematic species-group names in Europe's Neogene freshwater Gastropoda, pp. 453-468 in Zootaxa 3785 (3) on pages 464-465, DOI: 10.11646/zootaxa.3785.3.7, http://zenodo.org/record/491336
