Business on television: continuity, change and risk in the development of television’s ‘business entertainment format’

This article traces the evolution of what has become known as the business entertainment format on British television. Drawing on interviews with channel controllers, commissioners and producers from across the BBC, Channel 4 and the independent sector this research highlights a number of key individuals who have shaped the development of the business entertainment format and investigates some of the tensions that arise from combining entertainment values with more journalistic or educational approaches to factual television. While much work has looked at docusoaps and reality programming, this area of television output has remained largely unexamined by television scholars. The research argues that as the television industry has itself developed into a business, programme-makers have come to view themselves as [creative] entrepreneurs thus raising the issue of whether the development off-screen of a more commercial, competitive and entrepreneurial TV marketplace has impacted on the way the medium frames its onscreen engagement with business, entrepreneurship, risk and wealth creation

Subsidies to Industry and the Environment

Governments support particular firms or sectors by granting low interest financing, reduced regulation, tax relief, price supports, monopoly rights, and a variety of other subsidies. Previous work in partial equilibrium shows that subsidies to environmentally sensitive industries increases output and pollution emissions. We examine the environmental effects of subsidies in general equilibrium. Since all resources are used, whether or not subsidies increase emissions depends on the relative emissions intensity and incentives to emit of the subsidized industry versus the emissions intensity and the incentives to emit of the industry which would otherwise use the resources. Since subsidies must move resources to a less productive use, the economy wide marginal product of emissions falls with an increase in any subsidy, tending to decrease emissions. On the other hand, subsidies tend to move resources to more emissions intensive industries. Thus, subsidies increase pollution emissions if resources are moved to an industry for which emissions intensity is high enough to overcome the reduction in emissions caused by lower overall marginal product of emissions. We show that, under general conditions, subsidies also increase the interest rate, thus causing the economy to over-accumulate capital. Steady state emissions then rise, even if emissions fall in the short run. We also derive an optimal second best environmental policy given industrial subsidies. The results indicate that, under reasonable conditions, subsidies raise the opportunity cost of environmental quality in the long run. Finally, we examine the relationship between growth and the environment with subsidies. Under more restrictive conditions, reducing some subsidies may offer a path to sustainable development by raising income and at the same time improving the environment.Subsidies, pork, price supports, output subsidies, input subsidies, pollution, emissions.

Tracking and data system support for the Mariner Mars 1971 mission. Volume 2: First trajectory correction maneuver through orbit insertion

The Deep Space Tracking and Data System activities in support of the Mariner Mars 1971 project from the first trajectory correction maneuver on 4 June 1971 through cruise and orbit insertion on 14 November 1971 are presented. Changes and updates to the TDS requirements and to the plan and configuration plus detailed information on the TDS flight support performance evaluation and the preorbital testing and training are included. With the loss of Mariner 8 at launch, a few changes to the Mariner Mars 1971 requirements, plan, and configuration were necessitated. Mariner 9 is now assuming the former mission plan of Mariner 8, including the TV mapping cycles and a 12-hr orbital period. A second trajectory correction maneuver was not required because of the accuracy of the first maneuver. All testing and training for orbital operations were completed satisfactorily and on schedule. The orbit insertion was accomplished with excellent results

Molecular ratchets - verification of the principle of detailed balance

We argue that the recent experiments of Kelly et. al.(Angew. Chem. Int. Ed. Engl. 36, 1866 (1997)) on molecular ratchets, in addition to being in agreement with the second law of thermodynamics, is a test of the principle of detailed balance for the ratchet. We suggest new experiments, using an asymmetric ratchet, to further test the principle. We also point out methods involving a time variation of the temperature to to give it a directional motion

Augmenting human memory using personal lifelogs

Memory is a key human facility to support life activities, including social interactions, life management and problem solving. Unfortunately, our memory is not perfect. Normal individuals will have occasional memory problems which can be frustrating, while those with memory impairments can often experience a greatly reduced quality of life. Augmenting memory has the potential to make normal individuals more effective, and those with significant memory problems to have a higher general quality of life. Current technologies are now making it possible to automatically capture and store daily life experiences over an extended period, potentially even over a lifetime. This type of data collection, often referred to as a personal life log (PLL), can include data such as continuously captured pictures or videos from a first person perspective, scanned copies of archival material such as books, electronic documents read or created, and emails and SMS messages sent and received, along with context data of time of capture and access and location via GPS sensors. PLLs offer the potential for memory augmentation. Existing work on PLLs has focused on the technologies of data capture and retrieval, but little work has been done to explore how these captured data and retrieval techniques can be applied to actual use by normal people in supporting their memory. In this paper, we explore the needs for augmenting human memory from normal people based on the psychology literature on mechanisms about memory problems, and discuss the possible functions that PLLs can provide to support these memory augmentation needs. Based on this, we also suggest guidelines for data for capture, retrieval needs and computer-based interface design. Finally we introduce our work-in-process prototype PLL search system in the iCLIPS project to give an example of augmenting human memory with PLLs and computer based interfaces

Electro-optical device for monitoring wire size

Device recognizes variations in wire size and is being used during computer memory-plane fabrication. Decrease in wire diameter, due to stretching, permits removal of wire from memory-plant mold. Monitoring provides means of detecting imperfect wire and permits fabrication of computer memory plane to be stopped prior to its insertion into mold

A production modeling approach to the assessment of the horseshoe crab (Limulus polyphemus) population in Delaware Bay

Horseshoe crab (Limulus polyphemus) is harvested commercially, used by the biomedical industry, and provides food for migrating shorebirds, particularly in Delaware Bay. Recently, decreasing crab population trends in this region have raised concerns that the stock may be insufficient to fulfill the needs of these diverse user groups. To assess the Delaware Bay horseshoe crab population, we used surplus production models (programmed in ASPIC), which incorporated data from fishery-independent surveys, fishery-dependent catch-per-unit-of-effort data, and regional harvest. Results showed a depleted population (B2003/=0.03−0.71) BMSY and high relative fishing mortality /FMSY=0.9−9.5). Future harvest (F2002strategies for a 15-year period were evaluated by using population projections with ASPICP software. Under 2003 harvest levels (1356 t), population recovery to BMSY would take at least four years, and four of the seven models predicted that the population would not reach BMSY within the 15year period. Production models for horseshoe crab assessment provided management benchmarks for a species with limited data and no prior stock assessmen
