  • We wish to stress three important caveats. First, our iden- tification strategy only allows us to speak to the effects of early childhood exposure. The effects of viewing by school-age children are also clearly important for policy, and our results do not directly inform that debate. Second, we can only identify long-run effects.

  • The tension structures discussed in this book are predominantly roofing forms created from pre-stressed cable nets, cable trusses, and continuous membranes (fabric structures). A unique feature in their design is form-finding an interactive process of defining the shape of a structure under tension. The book discusses the role of stable minimal surfaces (minimum energy forms occurring in natural objects, such as soap films) in finding optimal shapes of membrane and cable structures.

  • By the early 1980s, mer- chandising was added to the mix, so tie-ins with fast-food chains, automo- bile companies, and lines of toys and apparel could keep selling the movie. Scripts that lent themselves to mass marketing had a better chance of being acquired, and screenwriters were encouraged to incorporate special effects. Unlike studio-era productions, the megapicture could lead a robust afterlife on a soundtrack album, on cable channels, and on videocassette. By the mid-1980s, once overseas income and ancillaries were reckoned in, few films lost money....

  • As new species emerged and evolved into disparate new forms, other species became extinct. And just as the origin of species and disparity form large-scale patterns, extinctions have formed patterns of their own. One of those patterns is illustrated in . It shows how the extinction rate has gone up and down over the past 540 million years. A few pulses of extinctions stand out above the others. These mass extinctions were truly tremendous cataclysms. The biggest of all, which occurred 250 million years ago, claimed 55% of all gen- era.

  • The adjustable keyboard surfaces in cluster workstations also fix the position of the computer, making the workstation less flexible for other tasks. The optimum positioning of the VDU monitor to minimise screen reflections and background glare is also inhibited. Convenient height adjustment for the whole of the work surface should be aimed for.

  • Accordingly, the Government has been considering the feasibility of getting local TV services on to the non-DTT platforms and has held discussions with these providers. The costs associated with broadcasting on the satellite platform in particular are likely to be prohibitive to most local TV service providers, primarily due to the high cost of transponder capacity that would be required in each location. In addition, the degree of localness that can be provided largely mirrors the current regional television structure rather than a specifically local one.
