The computerized information centre of the European Atomic Energy Community has become operational. A survey of its principal characteristics is given, and the main problems that arose in the development phase of the system are discussed. The Euratom Thesaurus includes graphic representation of relationships between indexing terms. A dual vocabulary allows specific indexing for high relevance and generic indexing for high recall. Retrieval strategy involves utilization of Boolean operators and frequency‐of‐occurrence tables. Recall ratio can be determined graphically by a continuous approach method. Indexing consistency tests show that it pays to use subject specialists. Users' needs are discussed in terms of subject coverage, specificity, rapidity, and presentation. The user service comprises retrospective searches on request as well as a customer profile service on subscription. There are three types of relevance, and various ways of bringing system relevance to coincide with user relevance. The Centre's budgetary requirements are low, due to circumspect use of its computer, an IBM 360, model 40. Its aims are centralization of documentation in the nuclear field and international co‐operation.

The purposes of a subject index in a small information service are examined and the organizational aspects of the Big information Centre and the Small Service in relation to the descriptor level are analyzed. The advantages of co‐ordinate indexing versus the conventional hierarchical classification in meeting complex information needs are pointed out. Through an evaluation of the flexible structure of the thesauri, the lower‐level but otherwise similar vocabulary needs of the small service are discussed. The use of the UDC to effect the level transitions required to adapt the thesauri to the needs of the Small Service is examined. It is shown how an improved subject index for the Soreq book collection has been constructed by the combined use of the EURATOM Thesaurus and the UDC. Examples to illustrate the design of this index are given. In the interest of expanding the co‐operation between the small Service and big centre, the idea of a multi‐level thesaurus is proposed.

One of the essential problems in scientific documentation is the establishment of relationships between:

The rolling inertia moment can be obtained by substitution of liquation (1) in liquation (9). Thus:

The real costs of trade, the transport and other costs of doing business internationally, are very important determinants of a country's ability to participate fully in the world economy. Remoteness and poor transport and communications infrastructure isolate countries, inhibiting their participation in global production networks. This paper investigates the dependence of transport costs on geography and infrastructure It shows that infrastructure is quantitatively important in determining transport costs, and improvements in infrastructure can dramatically increase trade flows. It also finds that the low level of Northeast Asian countries' trade flows is largely due to poor infrastructure. Competition among countries in East Asia to maintain or become a logistic hub in the region is severe. This is reflected in the competition to build or expand airports and seaports in the region. Competing countries need to find ways of cooperating to achieve an efficient resource allocation in the region as a whole.

‘The age of miracles is over,’ they say, attributing the wonders of today's world to technology. But if the advertisement for a ‘Language Translator’ is to be believed, we must continue to accept marvels. With this personal pocket computer it is claimed that, ‘You can communicate in a foreign country without speaking the language, or you can learn the language more easily thanks to a new electronic miracle.’ We are further told that the gadget translates words and phrases into and out of six languages.

The pattern of food prosecutions in more recent times has remained relatively unchanged. Most have been taken under Section 2, Food and Drugs Act, 1955, even for foods which have obviously been unfit for human consumption. The Section because of its wider application has distinct procedural advantages. A few local authorities routinely use Section 8 successfully; it probably depends upon a more liberal interpretation and understanding by local justices. The five‐year study of food prosecutions, (BFJ 1971, 73, 39), separated them into a number of well‐defined groups and showed that those for the presence of foreign material were the majority and remained fairly constant throughout the period; mouldy foods increased during the five years and then remained steady as the second largest single group. The foods most commonly affected and the foreign matter commonly present could be seen; neither changed much during the period of the survey.
