Booth of the Lithographic Technical Foundation, Inc. at the Lithographic Technical Forum

This photo of the Lithographic Technical Forum shows the booth of the Lithographic Technical Foundation, Inc. The foundation was founded in 1924 to foster research and education in the lithography industry. The slogan "Research to improve lithography . . . Education to improve craft skill" can be seen at the very top of the booth. A group of people are depicted looking at the range of educational material about lithography on display. Black and white photograph.

Three people are posed in front of the Lithographic Technical Foundation, Inc. booth at the Lithographic Technical Forum. The Lithographic Technical Foundation was founded in 1924 as an industry organization to promote research and education. In the 1960s the foundation changed its name to the Graphic Arts Technical Foundation and in the late 1990s merged with Printing Industry America. The organization ha a number of educational materials about lithography on display. Black and white photograph.

Can sustainable cotton production systems be developed for tropical northern Australia?

This article reviews research coordinated by the Australian Cotton Cooperative Research Centre (CRC) that investigated production issues for irrigated cotton at five targeted sites in tropical northern Australia, north of 21°S from Broome in Western Australia to the Burdekin in Queensland. The biotic and abiotic issues for cotton production were investigated with the aim of defining the potential limitations and, where appropriate, building a sustainable technical foundation for a future industry if it were to follow. Key lessons from the Cotton CRC research effort were: (1) limitations thought to be associated with cotton production in northern Australia can be overcome by developing a deep understanding of biotic and environmental constraints, then tailoring and validating production practices; and (2) transplanting of southern farming practices without consideration of local pest, soil and climatic factors is unlikely to succeed. Two grower guides were published which synthesised the research for new growers into a rational blueprint for sustainable cotton production in each region. In addition to crop production and environmental impact issues, the project identified the following as key elements needed to establish new cropping regions in tropical Australia: rigorous quantification of suitable land and sustainable water yields; support from governments; a long-term funding model for locally based research; the inclusion of traditional owners; and development of human capacity.

Forestry Impacts on Freshwater Habitat of Anadromous Salmonids in the Pacific Northwest and Alaska: requirements for protection and restoration

This synthesis presents a science overview of the major forest management Issues involved in the recovery of anadromous salmonids affected by timber harvest in the Pacific Northwest and Alaska. The issues involve the components of ecosystem-based watershed management and how best to implement them, including how to: Design buffer zones to protect fish habitat while enabling economic timber production; Implement effective Best Management Practices (BMPs) to prevent nonpoint-source pollution; Develop watershed-level procedures across property boundaries to prevent cumulative impacts; Develop restoration procedures to contribute to recovery of ecosystem processes; and Enlist support of private landowners in watershed planning, protection, and restoration. Buffer zones, BMPs, cumulative impact prevention, and restoration are essential elements of what must be a comprehensive approach to habitat protection and restoration applied at the watershed level within a larger context of resource concerns in the river basin, species status under the Endangered Species Act (ESA), and regional environmental and economic issues (Fig. ES. 1). This synthesis 1) reviews salmonid habitat requirements and potential effects of logging; 2) describes the technical foundation of forest practices and restoration; 3) analyzes current federal and non-federal forest practices; and 4) recommends required elements of comprehensive watershed management for recovery of anadromous salmonids.

Real-time data processing of interferential imaging spectrometer based on FPGA

Based on the data processing technologies of interferential spectrometer, a sort of real-time data processing system on chip of interferential imaging spectrometer was studied based on large capacitance and high speed field programmable gate array( FPGA) device. The system integrates both interferograrn sampling and spectrum rebuilding on a single chip of FPGA and makes them being accomplished in real-time with advantages such as small cubage, fast speed and high reliability. It establishes a good technical foundation in the applications of imaging spectrometer on target detection and recognition in real-time.

Technology education, science and science education : exploring the relationship

In this paper the nature of technology education in relation to science and science education is explored. Ways forward are indicated for both technology and science in the curriculum so that the two areas can be mutually supportive. In the 1990s, when curriculum writers were attempting to provide technology a unique place in the curriculum, they tended to downplay the relationship between technology and science. One reason for this tendency derives from a perception that science is an academic and elitist discipline and technology is well served by emphasizing the distance between the two. The other reason is perhaps political, that science, by virtue of its status in the community, and the status of its special type of knowledge, would be in a position, if allowed, to subsume the new subject. There are philosophical and historical precedents that justify such a concern. In tracing the historical relationships between science and technology, in professional practice, in philosophical positioning, and in school curriculum, we inevitably need to deal with the politics of school subjects.

The position taken in this paper is that science and technology are different, both in their epistemological foundations, and in the nature of the professional communities and the concerns of individual practitioners within the two areas. In clarifying these differences the essential nature of technology and of science are illuminated. The paper also explores ways in which the two areas can benefit from each other’s existence in the curriculum, and ways of approaching teaching that both clarifies the special nature of each type of knowledge, and allows them to be mutually supportive. This may necessitate a reconstruction of the nature of school science.
