Focus groups of value concepts of producers: National Report Netherlands
The Organic Revision project was funded by the EU with the aim of supporting the further development of the EU Regulation 2092/91 on organic production. As part of the project focus groups were run in five European countries on value concepts of organic producers and other stakeholders, during 2004-2005. The project aims to provide an overview of values held among organic stakeholders, and of similarities and differences among the various national and private organic standards.
In the Netherlands four focus groups were held, one pre-test with researchers, and three groups with established organic producers both of livestock and horticulture. It was not possible to recruit any newly converted producers to a meeting in the Netherlands.
The following conclusions were reached: Summarising the values in the words of the participants of these focus groups, organic agriculture could be defined as follows:
"Organic agriculture is about producing endlessly, with care and respect for humans, animals, plants and soil. Organic farmers produce healthy and tasty food without harming the environment or the development of others. Their farms and agriculture in general are
inter-connected with small and big world problems."
Overall there seem to be many similarities between the groups. Values related to all principles were discussed in all the groups; the differences observed were related to the different backgrounds.
The researchers spoke about their own experiences from work but also about their ideas from a consumer’s point of view. For the dairy farmers animal welfare was an important value while soil was more important to the arable farmers. Also with regard to the values nearness and proximity, differences between arable and dairy farmers seemed to reflect their daily practice. Arable farmers are faced with an anonymous market, with high and changing quality standards of the trade, and regard local production and consumption as a solution to their problems. The other groups of farmers also support this quest for another economic system. The researchers mention the unrealistic ideas of consumers concerning organic agriculture and they wonder how to make consumers more aware. The farmers would like to educate the consumer more, also about the relation of production in their country compared with production and development elsewhere. The farmers see the inter-connectedness of agriculture with income and development in developing countries very clearly and for some this was an important argument to convert. The farmers have a great feeling of responsibility for the world (ecologically and socially). For all of them the intentions are more important than the norms.
On the basis of the coding, it appears that values in relation to three principles were most important in the discussion. These are the ecology principle, holism and systems approach and professional pride, in order of importance. The following values were mentioned in relation to the principle of ecology: Recycling (the cycle) and saving energy were of major importance and nature conservation or nature integration on the farm was an important aim for some farmers. Co-operation between arable and animal production is seen as a very important means to close the cycle. And in the Netherlands with far going specialisation of farms this is sometimes a real challenge. Conflicts with the economy easily arise but also conflicts with national legislation restrict the farmers in their development. The values itself are not experienced as restricting. All groups except for the arable farmers see a combination and balance of all principles as important in the future. Arable farmers see the soil as most important and other values as complementary. All groups of experienced farmers were worried about new converters, who seem to stick to the minimum values, as a threat to their profession. All participants seem to have the feeling to be part of the good guys and are being recognised by society in that way. They are proud of their profession and the sector. For the continuation of the sector a clear distinction from conventional agriculture is needed, but they are not afraid that conventional moves in the direction of organic.
For the future, steady development and growth is preferred above fast growth. Others should also get the chance and time to develop in the way they did, but the new converters should not decrease the credibility of organic. Therefore, acceptable minimum rules should do justice to the values held by the sector as a whole
Animal breeding in organic farming
After a general introduction into the available breeding techniques for animal breeding and an overview of the organic principles, points for discussion are identified and scenario's for organically accepted breeding methods are discussed
Konsum ökologischer Milch aus gesundheitlichen Gründen - Eine qualitative Erhebung auf deutschen Demeter Milchviehbetrieben und bei ihren Kunden
Supposedly beneficial nutritional compositions were found in organic milk. Studies
report that the consumption of organic milk products affects health eg. prevention of
eczema in children. Single cases describe a better digestibility of organic milk for
consumers suffering from diverse atopic disorders and food allergies. To clarify
whether this is a real phenomenon, a survey in combination with interviews was carried
out on bio-dynamic milk farms and with affected consumers in Germany. The
results show that there are consumers which are buying fresh bio-dynamic raw milk
because of a better personal digestibility
Veränderungen im Bildaufbau in der Steigbildmethode durch die Alterung von Milch
The Uni Kassel, FG bio-dynamic agriculture, wants to use the capillary dynamolysis
according to Wala (Steigbildethode) for milk samples from different collection-days.
Based on former methodological investigation (Zalecka 2006) the aim of the study is
to show the aging effect and to test, whether a once taken sample represents the
farm. Result: the repeatedly taken samples seem to be equal, but variation in the
climatic conditions of the chamber as well as aging of the solution have a tremendous
influence on the pictures and must be standardised
A Search for Active Galactic Nuclei in Sc Galaxies with H II Spectra
(Abridged) We have searched for nuclear radio emission from a statistically
complete sample of 40 Sc galaxies within 30 Mpc that are optically classified
as star-forming objects, in order to determine whether weak AGNs might be
present. Only three nuclear radio sources were detected, in NGC 864, NGC 4123,
and NGC 4535. These galaxies have peak 6-cm radio powers of 10^{20} W/Hz at
arcsecond resolution, while upper limits of the non-detected galaxies typically
range from 10^{18.4} to 10^{20} W/Hz. The three nuclear radio sources all are
resolved and appear to have diffuse morphologies, with linear sizes of ~300 pc.
This strongly indicates that circumnuclear star formation has been detected in
these three H II galaxies. Comparison with previous 20-cm VLA results for the
detected galaxies shows that the extended nuclear radio emission has a flat
spectrum in two objects, and almost certainly is generated by thermal emission
from gas ionized by young stars in the centers of those galaxies. The 6-cm
radio powers are comparable to predictions for thermal emission that are based
on the nuclear H-alpha luminosities, and imply nuclear star formation rates of
0.08-0.8 solar masses/yr, while the low-resolution NRAO VLA Sky Survey implies
galaxy-wide star formation rates of 0.3-1.0 solar masses/yr in stars above 5
solar masses. Although the presence of active nuclei powered by massive black
holes cannot be definitively ruled out, the present results suggest that they
are likely to be rare in these late-type galaxies with H II spectra.Comment: To appear in ApJ. 7 page
Radio Emission Signatures in the Crab Pulsar
Our high time resolution observations of individual pulses from the Crab
pulsar show that both the time and frequency signatures of the interpulse are
distinctly different from those of the main pulse. Main pulses can occasionally
be resolved into short-lived, relatively narrow-band nanoshots. We believe
these nanoshots are produced by soliton collapse in strong plasma turbulence.
Interpulses at centimeter wavelengths are very different. Their dynamic
spectrum contains regular, microsecond-long emission bands. We have detected
these bands, proportionately spaced in frequency, from 4.5 to 10.5 GHz. The
bands cannot easily be explained by any current theory of pulsar radio
emission; we speculate on possible new models.Comment: 26 pages, 10 figures, to appear in Ap
The Contribution of Participation to the Grassland Research of the Louis Bolk Institute
Participatory research methods are well described, but the contribution of participation to the R&D process often remains unreported. In this paper some benefits of participatory on-farm research (OFR) carried out by the Louis Bolk Institute (LBI) are highlighted
A Wide Field, Low Frequency Radio Survey of the Field of M31: I. Construction and Statistical Analysis of the Source Catalog
We present here the results of a 325 MHz radio survey of M31, conducted with
the A-configuration of the Very Large Array. The survey covered an area of 7.6
deg, and a total of 405 radio sources between \la6\arcsec and 170\arcsec
in extent were mapped with a resolution of 6\arcsec and a 1 sensitivity
of 0.6 \mjyb. For each source, its morphological class, major axis
, minor axis , position angle , peak flux ,
integrated flux density , spectral index and spectral curvature
parameter were calculated. A comparison of the flux and radial
distribution -- both in the plane of the sky and in the plane of M31 -- of
these sources with those of the XMM--LSS and WENSS radio surveys revealed that
a vast majority of sources detected are background radio galaxies. As a result
of this analysis, we expect that only a few sources are intrinsic to M31. These
sources are identified and discussed in an accompanying paper.Comment: 29 pages with 4 tables and 10 figures (JPEGs), accepted for

Evaluation of the ALMA Prototype Antennas
The ALMA North American and European prototype antennas have been evaluated
by a variety of measurement systems to quantify the major performance
specifications. Nearfield holography was used to set the reflector surfaces to
17 microns RMS. Pointing and fast switching performance was determined with an
optical telescope and by millimeter wavelength radiometry, yielding 2 arcsec
absolute and 0.6 arcsec offset pointing accuracies. Path length stability was
measured to be less than or approximately equal to 20 microns over 10 minute
time periods using optical measurement devices. Dynamical performance was
studied with a set of accelerometers, providing data on wind induced tracking
errors and structural deformation. Considering all measurements made during
this evaluation, both prototype antennas meet the major ALMA antenna
performance specifications.Comment: 83 pages, 36 figures, AASTex format, to appear in PASP September 2006

Der Arzt-Philosoph:Wissenschaftstheoretische und philosophische Implikationen eines ärztlichen Berufsethos nach Karl Jaspers
Die Frage nach einer expliziten Medizinethik in Jaspers’ Gesamtwerk steht im Zentrum der Studie. Die Tatsache, dass er in seinem Gesamtwerk keinen systematischen medizinethischen Traktat verfasst hat, gleichwohl sich Texte mit medizinethischem Charakter finden, berechtigt zum Arbeitsauftrag der Untersuchung. Methode: die in Jaspers’ Werk zur Ethik und Medizin verstreuten Aussagen mit medizinethischer Relevanz werden quellenanalytisch erhoben und vor dem Hintergrund seiner Philosophie analysiert. Inhalt: eine Medizinethik Jaspers’ ist nicht identisch mit einer Gesetzesethik, die vom Arzt die Befolgung klar definierter ethischer Gesetze fordert. Vielmehr haben seine allgemein formulierten medizinethischen Gedanken appellativen Charakter mit einem wissenschaftstheoretischen und einen philosophischen Ausgangspunkt. Das Bindeglied zwischen den beiden medizinethischen Ansätzen bildet das Ethos der Humanität
