A Schumpeterian Renaissance?

In the last few decades of the twentieth century, the attention paid to technical innovation in the economics and management literature and in social science generally has justified some such description as "a Schumpeterian renaissance". This article, in justifying the concept of such a renaissance, distinguishes in particular Schumpeter's work on the clustering of innovations and technological revolutions as a major contribution to contemporary theory. As always during his lifetime, the relevance of these ideas to his work on Business Cycles remains controversial but the debate on this topic has certainly enlivened the renaissance of neo-Schumpeterian economic theory and research.innovation clusters, technological revolution, Schumpeter, business cycles

Developing science, technology and innovation indicators: what we can learn from the past

The science-technology-innovation system is one that is continuously and rapidly evolving. The dramatic growth over the last twenty years in the use of science, technology and innovation (STI) indicators appears first and foremost the result of a combination between on the one hand the easiness of computerized access to an increasing number of measures of STI and on the other hand the interest in a growing number of public policy and private business circles in such indicators as might be expected in societies which increasingly use organised science and technology to achieve a wide variety of social and economic objectives and in which business competition is increasingly based on innovation. As highlighted on the basis of 40 years of indicators work, frontiers and characteristics that were important last century may well no longer be so relevant today and indeed may even be positively misleading.Technological Change, Science and Technology, Innovation, Statistical Indicators, Measurement of Economic Growth, Policy Making

FPGA implementation of real-time human motion recognition on a reconfigurable video processing architecture

In recent years, automatic human motion recognition has been widely researched within the computer vision and image processing communities. Here we propose a real-time embedded vision solution for human motion recognition implemented on a ubiquitous device. There are three main contributions in this paper. Firstly, we have developed a fast human motion recognition system with simple motion features and a linear Support Vector Machine(SVM) classifier. The method has been tested on a large, public human action dataset and achieved competitive performance for the temporal template (eg. ``motion history image") class of approaches. Secondly, we have developed a reconfigurable, FPGA based video processing architecture. One advantage of this architecture is that the system processing performance can be reconfigured for a particular application, with the addition of new or replicated processing cores. Finally, we have successfully implemented a human motion recognition system on this reconfigurable architecture. With a small number of human actions (hand gestures), this stand-alone system is performing reliably, with an 80% average recognition rate using limited training data. This type of system has applications in security systems, man-machine communications and intelligent environments

Australian teachers and the learning environment: an analysis of teacher response to TALIS 2013

Abstract: The OECD Teaching and Learning International Survey (TALIS) is the first international survey programme to focus on the learning environment and the working conditions of teachers in schools. The overarching aim of TALIS is to provide robust, policy relevant indicators and analysis on teachers and the learning environment for an international audience. It aims to provide an opportunity to examine best practice in education systems around the world, to allow countries to identify other education systems facing similar challenges to their own and to learn from other policy approaches. TALIS provides internationally comparable information in the areas of teacher demographic characteristics, school leadership, teacher professional development, systems of feedback and appraisals for the teaching workforce, school effectiveness, and teacher practices and beliefs. As was the case for the 2008 cycle of TALIS, the Department of Education (formerly DEEWR) again commissioned the Australian Council for Educational Research (ACER) to oversee and conduct the implementation of TALIS 2013 in Australia. In Australia, over 2000 teachers and 149 principals in 149 schools comprised the ISCED 2 sample. In the Australian context, ISCED 2 teachers are defined as teachers of students in lower secondary education or, more specifically, teachers of students in Years 7, 8, 9 or 10

Impacts of elevated atmospheric ozone on peatland below-ground DOC characteristics

Rising concentrations of tropospheric ozone are having detrimental impacts on the growth of crop and forest species and some studies have reported inhibition of the allocation of carbon below ground. The effects of ozone on peatland ecosystems have received relatively little attention, despite their importance within the global carbon cycle. During this study, cores from a Welsh minerotrophic fen and ombrotrophic bog were exposed to four ambient/ elevated ozone concentration regimes representing current and predicted 2050 profiles. A large and significant reduction in the concentration of porewater dissolved organic carbon (DOC) was recorded in the fen cores exposed to the elevated ozone concentrations (up to −55%), with a concurrent shift to a higher molecularweight of the remaining soil carbon. No effects of ozone on DOC concentrations or characteristics were recorded for the bog cores. The data suggest higher ozone sensitivity of plants growing in the fen-type peatland, that the impacts on the vegetation may affect soil carbon characteristics through a reduction in root exudates and that theremay have been a shift in the source of substrate DOC for microbial consumption from vegetation exudates to native soil carbon. Theremay also have been a direct effect of ozone molecules reacting with soil organic matter after being transported into the soil through the aerenchyma tissue of the overlying vegetation. These qualitative changes in the soil carbon in response to elevated ozone may have important implications for carbon cycling in peatland ecosystems, and therefore climate change

Experimentally validated continuous-time repetitive control of non-minimum phase plants with a prescribed degree of stability

This paper considers the application of continuous-time repetitive control to non-minimum phase plants in a continuous-time model predictive control setting. In particular, it is shown how some critical performance problems associated with repetitive control of such plants can be avoided by use of predictive control with a prescribed degree of stability. The results developed are first illustrated by simulation studies and then through experimental tests on a non-minimum phase electro-mechanical system

The British industrial revolution: The age of cotton, iron, and water power

The available statistics show that there was a sharp acceleration of the growth of British industrial output, investment, and trade in the last few decades of the eighteenth century, justifying the general use of the expression ‘Industrial Revolution’ and refuting the efforts of a few historians to deny its very occurrence. In particular, the extraordinarily rapid growth of output and exports of the cotton industry was widely remarked upon both at the time and ever since, and was generally and plausibly attributed to a series of inventions and innovations, which increased productivity per hour of work by more than an order of magnitude and made possible rapidly descending costs and prices. Only a little less rapid was the growth of the British iron industry, its rate of technical change, and its widening range of applications throughout the economy. These exceptionally dynamic industries made an outstanding contribution to the growth of the economy as a whole based on water‐powered mechanization and a new transport infrastructure of canals, rivers, and roads. Finally, British leadership in the Industrial Revolution must be attributed not only to these changes in technology and in the economy but also to the confluence and congruence of these changes with developments in the political and cultural subsystems particularly favourable to science, technology, and entrepreneurship. .info:eu-repo/semantics/publishedVersio

The emergence of a new techno‐eonomic paradigm : The age of Information and Communication Technology (ICT)

US technological leadership and domination of the world economy were further enhanced by the extraordinarily rapid rate of technical change and output growth in the semiconductor, computer, and telecommunications industries in which American firms played a leading role and to which American universities made a vital contribution. Whereas some historians have cast doubts on the pervasiveness and the magnitude of the effects of earlier technological revolutions, such as the railways, few doubt the significance of the Information Technology Revolution and some, such as Castells, see it as ushering in a new type of economy and even a new civilization. Just as in the 1920s the Hoover Report had stressed that changes in mass production technology and other business developments had given rise to a new style of management, so many economists and management consultants today stress the ways in which the new ICT infrastructure and especially the Internet are bringing in a new type of firm—the ‘network firm’ organizing both production and distribution in entirely new ways.Great uncertainty still attends more profound social and political changes associated with ICT including the diminished capabilities of national governments to tax and regulate powerful multinational firms and the rise of a new culture of ‘virtual reality’info:eu-repo/semantics/publishedVersio

The greenhouse gas (GHG) emissions associated with aquatic carbon removal during drinking water treatment

Peatlands and other terrestrial ecosystems export large amounts of dissolved organic carbon (DOC) to freshwater ecosystems. In catchments used for supplying drinking water, water treatment works (WTWs) can remove large quantities of this organic matter, and can therefore play a unique modifying role in DOC processing and associated greenhouse gas (GHG) emissions within the fluvial system. During this study we quantified the GHG emissions due to processes associated with carbon (C) removal during water treatment at four contrasting WTWs in the UK. Our results demonstrate that the removal of DOC from raw water supplies via coagulation, leading to the formation of sludge, usually makes it less susceptible to short-term oxidation when compared to DOC remaining in the fluvial system. Although this could be considered a means of reducing CO2 emissions from waterborne carbon, the current practise of land spreading of sludge is unlikely to represent a long-term C sink and therefore water treatment probably only delays the rate at which fluvial C re-enters the atmosphere. Furthermore, we estimate that indirect CO2 missions resulting from electricity use during water treatment, together with the use of chemicals and CO2 degassing from the water during treatment, far outweigh any potential CO2 reductions associated with DOC removal. Thus, the post-treatment handling of sludge has the potential to mitigate, but not to negate, GHG emissions associated with water treatment processes
