A Comparison of Agricultural Sector Models: CRAM, DRAM, SASM and the KVL Model
No full textFour different programming models dealing with the agricultural sectors in Canada, The Netherlands, Sweden and Denmark are analysed. The purpose is to construct a knowledge base for the development of a new sector model for Danish agriculture. This analysis has created a valuable set of resources for use in the development of the model.Agribusiness,

(Todarodes sagittatus (Lamarck)). Investigations in Norwegian coastal waters, in the northern North Sea and south of the Faroes during October 1978 - May 1979
No full textMaterials for investigation were collected during research cruises
in October-November in the coastal areas of western and northern
Norway, and in December 1978 - May 1979 in the northern North Sea
and south of the Faroes (Table l), During the autumn of 1978 T.sagittatus
mainly migrated to the Andfjord area in North Norway
where a fishery took place in October-December. Off northern
Norway the mean mantle length of the different samples was 33-34
cm, off western Norway 27-30 cm. In the northern North Sea most
squid taken during December-April measured 18-28 cm, a few 13-17
cm and 30-36 cm. Those taken in May had a mean length of 30 cm.
The total edible weight was on an average 74% of the total weight
(mantle 50%, arms and tentacles, 24%) .
Off northern Norway the liver weight constituted 12,6% (6-16) of
the total weight, off western Norway 10% (4-13), south of the
Faroes, 7.1% (3-13) .
Males are easily distinguished macroscopically by the condition of
the skin, becoming ragged and slimy very soon after capture, while
the females keep their skin firm and smooth.
Off northern Norway males constituted 8-25% of the stock, off
western Norway 4%. In the North Sea nearly as many males as females
were caught in December-April (10 male, 13 female) in May at the
Faroes, 30% were males. It is suggested that males are less willing
to take the hooks than the females.
All females taken were immature. In two males, mantle lengths 31
cm and 36.5 cm, caught in the North Sea in December, the gonads
weighed 7.2 and 13.0 g respectively, i.e. 2.0 and 1.0% of the
total weight. At the Faroes the gonads of the males were more or
less in an advanced stage of development, constituting 0.5-2.0%
of the total weight.
Food items in the stomachs were dominated by fish, off northern
Norway saithe, herring and redfish, at the Faroes blue whiting.
Euphausiids ranged second, squid third. It is suggested that the
high percentage of squid recorded earlier (WIBORG 1972, 1978) may
partly be an artifact, as arms and tentacles are torn off during
the fishery and then eaten by the squid.
Following LIPINSKY (1978), ageing of squid was attempted in studying
the statholiths under a microscope after grinding. Rings,
supposed to be daily growth rings, were seen, and countings seem
to confirm the earlier hypothesis (WIBORG 1972) of two populations
of T. sagittatus, spawning during December-January and May-July
respectively.
Location of squid with echo sounders and fishing experiments with
Japanese jigging machines were successful. T. sagittatus is now
readily accepted for human consumption

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
A Relatively Easy-Access Description of the Logistics, Purposes and Function of the Sector Model KRAM
No full textThis working paper describes the design of KRAM; a model of the Danish agricultural sector that has been developed in a research project at KVL between 1997 and 2000. The purpose of this paper is to give a general and non-technical overview of the model. The paper is directed at people who want a more detailed knowledge of the model, but without addressing the underlying formulas and programs. The paper focuses on the logistics of the model. This includes how data are produced and utilized within the model and how the various submodels are designed and work together. Furthermore the calibration and solving procedures and the time aspects of the models are described. Some of these descriptions may appear somewhat interim due to the fact that the model itself was not fully operational when this paper was published.Agribusiness,
