Maintaining financial stability:challenges in a changing financial landscape
No full textToenemende mondialisering en liberalisatie zijn er oorzaken van dat financiële markten steeds complexer geworden. Financiële schokken worden bovendien steeds sneller doorgegeven van de ene aan de andere partij. Dit alles maakt de taak van bancaire toezichthouders moeilijker. Het proefschrift van Sander Oosterloo richt zich op de vraag welke rol centrale banken hebben bij het hoeden van financiële stabiliteit. Ook vroeg hij zich af of de integratie van de Europese bancaire markt tot gevolg heeft dat de huidige toezichtstructuur moet worden herzien. Het proefschrift laat zien dat er niet overal dezelfde invulling wordt gegeven aan de financiële stabiliteitsfunctie van centrale banken. Daarnaast komt Oosterloo tot de slotsom dat bancaire toezichthouders als gevolg van de toenemende integratie op termijn binnen een Europees Stelsel van Financiële Toezichthouders moeten gaan opereren

The HI halo of spiral galaxies
No full textA deep H I survey with the VLA of the spiral galaxy NGC 2403 has revealed the existence of a thick, low density layer of neutral gas surrounding the thin 'cold' disk. This layer has a mean rotation velocity 25-50 km s(-1) lower than that of the disk and a 10-20 km s(-1) inflow towards the centre of the galaxy. In the central parts there are velocity differences from rotation of up to 150 km s(-1). Chandra observations of NGC 2403 show a diffuse, hot X-ray emitting gas component with a temperature of a few 106 K. These results point at galactic fountain type of flows between disk and halo. 'Halo' gas with similar characteristics has also been observed in other spiral galaxies (e.g. NGC 6946, NGC 891). Such gas is probably similar to the IVCs and to some of the HVCs of the Milky Way
Kinematics of the ionised gas in the spiral galaxy NGC 2403
No full textWe present a study of the kinematics of the ionised gas in the nearby spiral galaxy NGC 2403 using deep long-slit spectra obtained with the 4.2-m William Herschel Telescope. The data show the presence of a halo component of ionised gas that is rotating more slowly than the gas in the disk. The kinematics of this ionised halo gas is similar to that of the neutral halo gas. On small scales. broad line profiles (up to 300 km s(-1) wide) indicate regions of fast Outflows of ionised gas. We discuss these new results in the context of galactic fountain models
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
HI study of the warped spiral galaxy NGC5055: a disk/dark matter halo offset?
No full textWe present a study of the Hi distribution and dynamics of the nearby spiral galaxy NGC 5055 based on observations with the Westerbork Synthesis Radio Telescope. The gaseous disk of NGC5055 extends out to about 40 kpc, equal to 3.5 R-25, and shows a pronounced warp that starts at the end of the bright optical disk ( R-25 = 11.6 kpc). This very extended warp has large-scale symmetry, which along with the rotation period of its outer parts (similar or equal to 1.5 Gyr at 40 kpc), suggests a long-lived phenomenon. The rotation curve rises steeply in the central parts up to the maximum velocity (v(max) similar or equal to 206 km s(-1)). Beyond the bright stellar disk (R-25), it shows a decline of about 25 km s(-1) and then remains flat out to the last measured point. The standard analysis with luminous and dark matter components shows the dynamical importance of the disk. The best fit to the rotation curve is obtained with a "maximum disk". Less satisfactory fits with lighter disks help to set a firm lower limit of 1.4 to the mass-to-light ratio in F band of the disk. Such a "minimum disk" contributes about 60% of the observed maximum rotational velocity. NGC 5055 shows remarkable overall regularity and symmetry. A mild lopsidedness is noticeable, however, both in the distribution and kinematics of the gas. The tilted ring analysis of the velocity field led us to adopt different values for the kinematical centre and for the systemic velocity for the inner and the outer parts of the system. This has produced a remarkable result: the kinematical and geometrical asymmetries disappear, both at the same time. These results point at two different dynamical regimes: an inner region dominated by the stellar disk and an outer one, dominated by a dark matter halo offset with respect to the disk
Dwarfs walking in a row. The filamentary nature of the NGC 3109 association.
No full textWe re-consider the association of dwarf galaxies around NGC 3109, whose known members were NGC 3109, Antlia, Sextans A,
and Sextans B, based on a new updated list of nearby galaxies and the most recent data. We find that the original members of the
NGC 3109 association, together with the recently discovered and adjacent dwarf irregular Leo P, form a very tight and elongated
configuration in space. All these galaxies lie within 100 kpc of a line that is ' 1070 kpc long, from one extreme (NGC 3109) to the
other (Leo P), and they show a gradient in the Local Group standard of rest velocity with a total amplitude of 43 km s
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
