The article focuses on an information system to exploit the use of metadata within film and television production. It is noted that the television and film industries are used to working on big projects. This involves the use of actual film, video tape, and P.E.R.T charts for project planning. Scripts are in most instances revised. It is essential to attach information on these in order to manage, track and retrieve them. The use of metadata eases the operations involved in these industries.

The television and film industries are used to working on large projects. These projects use media and documents of various types, ranging from actual film and videotape to items such as PERT charts for project planning. Some items, such as scripts, evolve over a period and go through many versions. It is often necessary to attach information to these “objects” in order to manage, track, and retrieve them. On large productions there may be hundreds of personnel who need access to this material and who in their turn generate new items which form some part of the final production. The requirements for this industry in terms of an information system may be generalized and a distributed software architecture built, primarily using the internet, to serve the needs of these projects. This architecture must enable potentially very large collections of objects to be managed in a secure environment with distributed responsibilities held by many working on the production.

This article examines the first major British television series about the First World War, The Great War (BBC, 1964), in terms of its cultural, historical and aesthetic significance. As a central component of the BBC`s 50th anniversary commemorative programme to mark the outbreak of war, the series was a major media event -a small-screen memorial cast in sounds and images instead of stone and bronze. This article looks at how the British television audience responded to this form of on-screen commemoration. Material for this article was derived from the series' extensive production records housed in the BBC Written Archives Centre at Caversham, Berkshire. This was supplemented by, among other sources, material from interviews and correspondence with several surviving members of the production team. This allows a broader understanding of the motivations of those involved in the production of a groundbreaking historical series, while acknowledging the wide-ranging nature of its audience.

We review current knowledge and understanding of the biology and ecology of Centropages typicus in the European shelf-seas (e.g. North Sea, English Channel and Bay of Biscay). Our study is based on observations at seven coastal time-series stations as well as on the Continuous Plankton Recorder dataset. This paper focuses on the influence of the environmental parameters (e.g. temperature and Chla) on the life cycle and distribution of C typicus and provides a comparison with its congeneric species C. hamatus and C. chierchiae in the study area. Data on abundance, seasonality and egg production have been used to define the temperature and chlorophyll optima for occurrence and reproduction of Centropages spp. within this region of the European shelf-seas.

The present article analyses the preferences of the deaf who use sign language and are users of the TV interpretation service to sign language, as well as the characteristics with which TV channels provide that service in television in Spain. The objective is to establish whether the way in which the aforementioned accessibility service is provided matches the preferences of users or differ from them. The analysis presents the opinion on this service of the deaf that use the Spanish sign language as their first language for communication. A study has also been conducted on the programmes broadcast with sign language during week 10-16/03/2014. The main data collected reveal that the deaf are dissatisfied with broadcasting times. They ask for news programmes with sign language, they would rather have the interpretation carried out by deaf people who use sign language and they prefer that the interpreter is the main image on screen. Concerning the analysis of the programmes broadcast, the study shows that the majority of programmes with sign language are broadcast at night, they are entertainment programmes, the interpretation is carried out by hearing people who use sign language and that their image is displayed in a corner of the screen.

We consider the problem of train planning or scheduling for large, busy, complex train stations, which are common in Europe and elsewhere, though not in North America. We develop the constraints and objectives for this problem, but these are too computationally complex to solve by standard combinatorial search or integer programming methods. Also, the problem is somewhat political in nature, that is, it does not have a clear objective function because it involves multiple train operators with conflicting interests. We therefore develop scheduling heuristics analogous to those successfully adopted by train planners using ''manual'' methods. We tested the model and algorithms by applying to a typical large station that exhibits most of the complexities found in practice. The results compare well with those found by traditional methods, and take account of cost and preference trade-offs not handled by those methods. With successive refinements, the algorithm eventually took only a few seconds to run, the time depending on the version of the algorithm and the scheduling problem. The scheduling models and algorithms developed and tested here can be used on their own, or as key components for a more general system for train scheduling for a rail line or network.Train scheduling for a busy station includes ensuring that there are no conflicts between several hundred trains per day going in and out of the station on intersecting paths from multiple in-lines and out-lines to multiple platforms, while ensuring that each train is allowed at least its minimum required headways, dwell time, turnaround time and trip time. This has to be done while minimizing (costs of) deviations from desired times, platforms or lines, allowing for conflicts due to through-platforms, dead-end platforms, multiple sub-platforms, and possible constraints due to infrastructure, safety or business policy.
