AbstractNew technology allows the rapid mapping of point or polygon variables, the correlation of maps, and the use of maps as variables in computer models. An illustration is the use of map correlation to investigate how changes in abundance of adult grasshoppers relate to rainfall in Alberta: maps of monthly rainfall, monthly hours of sunlight and annual grasshopper counts (8391 survey records) from a 5-year period were contoured and correlated. The methods of smoothing are described. Correlograms of Moran's I over distance show spatial autocorrelation of grasshopper abundance on a geographic scale. The grasshopper counts were autocorrelated to 20–30 km on most maps, and the relationship of correlograms to contour mapping is discussed. Quotient maps were produced: each population–abundance map was divided by the map from the previous year, and the results were correlated with monthly rainfall maps. There was significant association between areas of increase and levels of rainfall. Population tended to decline in areas of above-average rainfall. A simple model enabled a forecast of grasshopper distribution from the previous year's grasshopper population, monthly rainfall maps, and sunlight hours during the previous August.

In modern day architecture practice, the role of the hand in the design process has been displaced by the advent of new technology. There is an inherent desire in practice to rely fully on the computer, which within its digital parameters removes the direct connection of the architect’s hand from the creative process. To create meaningful architecture, it is imperative to understand that the relationship of the architect’s hand in the design process is as critical as the relationship of the architectural joint to the project. To understand the hand, I approached it architecturally and rigorously studied its form and structure. At the same time, I studied several sculptors and artists, such as Richard Serra, Eduardo Chillida, Robert Morris and Eva Hesse who concentrated on the process over the final product.  I created section drawings of select pieces and analyzed them with hand motions to study their forms. With these analyses, I created a material joint that explored different ways to “hold” masses and “join” different materials. With my hand analyses and material joints, I have understood the level of the “joint” at different scales: from the hand that makes the architecture to the actual structure that holds architecture together.

This volume contains edited versions of 13 of the papers presented at a 1994 University of Edinburgh conference entitled, “Issues and Perspectives in Language Learning: Scottish and Wider Dimensions.” The general topics include: I. The typical pattern of studies in language departments (four papers), II. The relationship of different parts of degree curricula (four papers), III. Languages in the working world; learners, their backgrounds and expectations (one paper), IV. Developments of new methods and using new technology (three papers), V. The particular place of language study in Scotland (one paper), and VI. A summary report of the Round Table discussions.

This paper investigates the role of social learning in the diffusion of a new agricultural technology in Ghana. We use unique data on farmers' communication patterns to define each individual's information neighborhood. Conditional on many potentially confounding variables, we find evidence that farmers adjust their inputs to align with those of their information neighbors who were surprisingly successful in previous periods. The relationship of these input adjustments to experience further indicates the presence of social learning. In addition, applying the same method to input choices for another crop, of known technology, correctly indicates an absence of social learning effects. (JEL D83, O13, O33, Q16)

CFRP(Carbon Fiber Reinforced Plastics) reinforced structure, as one kind of new technology, has been applied extensively in concrete structure, and CFRP reinforced masonry structure has been began studying and applied. But reliability research of masonry strengthened with CFRP is less, which restrains applying of CFRP. In the paper, Combined with the theory of reliability and tests, supposed that it is basic random variable that strength of brick and mortar and geometry dimension of members and effect of load, it is established that the stability probabilistic formula of brick column reinforced by CFRP under axial-loading. Its reliability is calculated, by means of Matlab. Under the action of different loads and total loads being constant, it is analyzed that the relationship of index of reliability and ratio of loading effect. Some useful results are gotten. And the result calculated is reasonable and reliable and it may supply engineering personnel with computer basis.

In the development of architectural representation, the image has become a metonym of architectural experience. This productive tension is maintained by the expectation of fragmented representation to identify and reproduce the experiential and phenomenological dimensions perceived in the physical experience with architecture. Returning to the investigation of representation and perception exemplifies that each new technology introduces a new scale of extension in both design capability and opportunity for feedback. The degree of immersivity introduced by virtual reality technologies elicits several scales of experience. This thesis uses virtual prototyping in the design stage to elicit a product that is not a reflection of intention, but a result of something discovered, evaluated and experienced in immersion prior to realization. An increase in receptivity to the qualities of the design and its context relative to the perceiver has the potential to change the relationship of digital space to digital place.

From the craft production of the Gothic to the standardised industrial production of the Bauhaus, this research follows the development of modern architecture and the evolution of façade construction. This paper examines how, as technology has continued to advance and modes of production have evolved, complete dematerialisation - defined in this paper as a non-structural glass exterior walls - of the façade was achieved with the curtain wall. This research aimed to establish a link between Gothic and Bauhaus architecture to propose a lineage for modern curtain wall façade production and construction. The paper argues that changing modes of production is in response to construction issues, technological innovation and are dependent on the socio-cultural context of a specific time. Presenting a lineage that places this evolution into three stages - pre-industrial, industrial, and post-industrial - the relationship of architecture, technology and how construction methods respond to new technology will be illustrated. This paper will examine the curtain wall's arrival in New Zealand as a case study for the international dissemination of this system, to conclude with a discussion that outlines how the architecture of a post-industrial age both favours and can produce customised and complex façades.

This article describes new techniques and technology for inspecting welds using automated ultrasonics. The prime new technology is phased arrays, while the new techniques are Time-of-Flight Diffraction and S-scan back diffraction. The relationship of phased arrays with North American codes is briefly given, along with an inspection result, comparing radiography, pulse-echo phased arrays and TOFD.

In this paper author has explored the relationship between technology and organization from the perspective of evolutionary economy. The technology is seen as the key source of dynamism in economic development. This have involved a discussion of the factors shaping long term trends in technological development, the relationship of innovation to economic progress and the role of organizations as sources of innovation activity. The technological innovations arc viewed as mutations which if successful result in variations in the economic environment. Success is in part a function of environmental selection by consumers and users. In order to survive, organizations must adopt to radically new and emergent technological and market conditions ('techno-economic paradigms'). To do this they must learn how to assimilate and apply the new knowledge required to bring about and sustain innovation. Organizations move from current pathways of technological development onto the completely new trajectory offered by new technology. They must play an active role in developing strategies that strengthen their innovative capacity. These processes determinate new organizational form innovative organization.
