Are covered bonds a substitute for mortgage-backed securities?
Covered bonds and mortgage-backed securities both allow mortgages to be financed with duration-matched bonds. Given the problems in the MBS market during the financial crisis, some suggest that covered bonds might be a substitute for MBS. We examine the use of covered bonds and MBS in the U.S. and Europe, finding that the two are used for different purposes. Covered bonds are used more to increase liquidity than are MBS. MBS are more often used in ways consistent with exploiting some kinds of agency problems.Bonds ; Mortgage-backed securities
Compositional analysis of correlation of weather parameters with russet of 'golden delicious' apples
The development of russet on 'Golden Delicious' apples is a problem of concern to growers of fresh
market apples. Russeting is considered to be due to untimely divisions of cells in the epidermis of the
fruit initiated by environmental or cultural conditions. The etiology of nonculturally induced russet
is intimately associated with the presence of water on the surface of the fruit. The initiation of russet
clearly occurs during the ¯rst 30 days of fruit development, and is frequently visible at the end of
that period. Creasy (1980) concluded that high relative humidity was positively correlated with the
degree of incidence of russeting, especially 16-25 days after full bloom of apple trees. This study was
conducted to establish the correlation between weather parameters and the incidence of russeting on
apples.
We have recorded the incidence rates of russeting on 'Golden Delicious' grown in 'Mas Badia' ¯eld
station (La Tallada, Girona), from 1986 to 2002. Each year a sample of apples was picked at random.
Each fruit was evaluated for the percent of surface area covered with russet which was categorized
into ¯ve ordinal categories. In this way we have the percentage of each russeting-category for each
year

Results of the meteorological model WRF-ARW over Catalonia, using different parameterizations of convection and cloud microphysics
The meteorological model WRF-ARW (Weather Research and Forecasting - Advanced ResearchWRF) is a new generation model that has a worldwide growing community of users. In theframework of a project that studies the feasibility of implementing it operationally at the Mete-orological Service of Catalonia, a verification of the forecasts produced by the model in severalcases of precipitation observed over Catalonia has been carried out. Indeed, given the impor-tance of precipitation forecasts in this area, one of the main objectives was to study the sensitivityof the model in different configurations of its parameterizations of convection and cloud micro-physics. In this paper, we present the results of this verification for two domains, a 36-km gridsize and one of 12 km grid size, unidirectionally nested to the previous one. In the externaldomain, the evaluation was based on the analysis of the main statistical parameters (ME andRMSE) for temperature, relative humidity, geopotential and wind, and it has been determinedthat the combination using the Kain-Fritsch convective scheme with the WSM5 microphysicalscheme has provided the best results. Then, with this configuration set for the external domain,some forecasts at the nested domain have been done, by combining different convection andcloud microphysics schemes, leading to the conclusion that the most accurate configuration isthe one combining the convective parameterization of Kain-Fritsch and the Thompson micro-physics scheme
New Gravity Map of the Western Galicia Margin:The Spanish Exclusive Economic Zone Project
Since 1995, the most intensive mapping of
the seafloor off the Spanish coast has been
carried out in the framework of the Spanish
Exclusive Economic Zone Project (ZEEE).The
main objectives of this project are to obtain
improved multibeam bathymetric cartography
of the areas off Spanish coastlines, and to perform
a geophysical survey,well-suited with a
10-knot navigation velocity (some techniques
requires lower navigation velocity).
The geophysical survey includes gravity, geomagnetism,
and low-penetration seismic techniques
in order to infer the geological structure
of the seafloor. Other oceanographic variables
such as current, surface salinity, and temperature
profiles, can be recorded without compromising
this systematic survey effort.
The ZEEE Project has carried out its survey
activities for one month every year.Data
acquisition is achieved aboard the Spanish
R/V Hesperides. Until 1997, surveying efforts
concentrated on the Balearic Sea and Valencia
Gulf, both in the western Mediterranean Sea.
Between 1998 and 2000, the ZEEE Project
investigations were conducted offshore the
Canary Archipelago. Since 2001, the third
phase of the program has been focused on
the West Galicia Margin in the northeastern
Atlantic Ocean.
Survey results on the West Galicia Margin area
are of interest for two key reasons. First, there
is great scientific interest in the improvement
of the knowledge of this non-volcanic rifting
margin, since this margin offers good conditions
for the study of the processes that take
place in this type of geological context,because
it is sediment-starved.
Second, the obtained results also have major
socioeconomic repercussions because they
can prove significant to defining the expansion
of the Spanish shelf,beyond Spain’s Economic
Exclusive Zone distance of 200 nautical miles.
All of the gravity data acquired to date on
this area have been stored as a database, with
the aim of preparing gravity anomaly maps
on a scale 1:200,000.The database and gravity
anomaly charts from the ZEEE Project will
provide the most coherent and complete gravity
perspective available for this area.
This article describes the efforts and accomplishments
of the project to date
Macromicetes de la comarca del Berguedá (Barcelona)
Se da cuenta de ciento cuarenta y ocho especies de macromicetes recolectadas en el transcurso de una serie de excursiones de estudio, realizadas por los autores entre los años 1974 al 1977, por diversas localidades de la comarca del Berguedá (Barcelona).Numerosas especies entre las indicadas fueron recolectadas en varias ocasiones, lo que permitió apreciar detalles de su comportamiento autoecológico.En todos los casos hemos pretendido confirmar las determinaciones taxonómicas utilizando los medios reseñados en la Bibliografia. De cada especie se dispone de su ficha de estudio, con los detalles apreciados al realizar la determinanción, pese a ello no hemos considerado adecuado dar descripciones por no hacer más extenso el presente trabajo.We remark the determinations of a hundred and forty eight species of Macromycets collected the year 1974 to the 1977, mainly in Berguedá district (Barcelona).Most of them could be studied more than once. We tried to confirm the determinations using the last specialized works
