The Annales de l’Industrie (1820–1827): A Technological Laboratory for the Industrial Modernization of France

In France, during the Restoration, various attempts at industrial modernization were made. One of these consisted in the circulation of technical ideas through industrial exhibitions and the technical press, the latter channel being represented by treatises, manuals, dictionaries and technological journals. One of the first of these journals was the Annales de l’industrie. This paper considers two aspects. First, the institutional environment: the French tradition of technological writing, the national industrial exhibitions, the legacy of the école centrale experiment, and the influence of the Parisian Royal Academic Society of Sciences. Second, an analysis of the contents of the journal is the occasion for a discussion of technological progress on the level of the traditional arts and crafts, the dominant mode of industrial production during the 1820s. Other themes discussed are the avoidance of scientific terminology, official innovation policy, Great Britain as the model to be emulated, and the tension between apprenticeship and modern technical education.     

Learning to think the past: Heritage,identity and state education in Wales

Abstract

Despite its problematic nature, the term Celtic is often linked with Wales and its history. Commonly regarded as a Celtic nation, the concept has been used to engender a sense of identity and also a sense of difference between Wales and other parts of the British Isles, particularly with England. As the national curriculum has been adapted to the needs of schools in Wales, some of these aims and objectives have been made explicit in many parts of the syllabus. Heritage sites in Wales also relate their history and present archaeology to a Celtic past and a case study of a specific site in Pembrokeshire is used to exemplify this approach. There is evidence that children find these portrayals of their past, as contained in the teaching in schools and site visits, interesting and informative. The dangers lie in the over‐simplification of the contested concept of Celticity and in the shortage of good evaluative assessments of these learning to think approaches.     

Robust Design of a Single Tuned Mass Damper for Controlling Torsional Response of Asymmetric-Plan Systems

A new robust design methodology to control the seismic performance of asymmetric structures equipped with a Single Tuned Mass Damper (STMD) is presented in this article. This design approach aims to control the seismic response of such systems by reducing both flexible-and stiff-edge maximum displacement. The dynamic problem has been investigated in the state space representation showing that the TMD works as a closed-loop feedback control action. A synthetic index to estimate the seismic performance of the main system has been defined by using H_∞ norm. Wide-ranging parametric numerical experimentation has been carried out to obtain design formulae for the STMD in order to minimize such a performance index. These formulae allow for a simple design of STMD position and stiffness to optimally control both translational and rotational motion components, whereas two mass devices are generally considered to improve the seismic performance of asymmetric structural systems The effectiveness and efficiency of the obtained design formulae have been tested by investigating the dynamic behavior of the asymmetric structure after being subjected to different recorded seismic inputs.

Numerical Analyses of the Effectiveness of Soft Barriers into the Soil for the Mitigation of Seismic Risk

An approach to mitigate the seismic risk of existing structures by means of the creation of a continuous thin layer of grouted soil at a convenient depth is presented. A parametric numerical analysis is reported using different constitutive models with reference to two geometrical schemes. It is shown that if the grouted layer has a stiffness significantly lower than that of the surrounding soil, it may be effective in reducing the seismic demand. In the parametric analyses, the positive role of yielding is also observed, which indicates that the barrier is more effective with larger input amplitudes.     

Tuned Mass Damper Positioning Effects on the Seismic Response of a Soil-MDOF-Structure System

Tuned mass dampers (TMDs) are effective structural vibration control devices. However, very little research is available on the experimental investigation of TMDs and their performance in systems undergoing dynamic soil-structure interaction. Geotechnical centrifuge tests are conducted to investigate story positioning effects of single and multiple TMDs in a soil-MDOF-structure system. The criteria for optimal story positioning will be established, and it is shown that story positioning influences TMD performance more than the number of TMDs used. Non-optimal story positioning was found to have the potential of reducing damping efficiency, amplifying peak structural response, and inducing lengthier high-intensity motion.     

(Education for) Sustainable Development in Geography Education: review and outlook from a perspective of Germany

Nearly 15 years after the Rio Conference and 10 years after the Lucerne Declaration on Geographical Education for Sustainable Development we are interested to what extent the goals of this declaration have been implemented? What role does Geography play in Education for Sustainable Development in higher education? We analyzed the modules of 107 degree programs with Geography as a degree major or as a teacher training subject at 55 German universities, technical colleges and universities of education. We conducted a quantitative text analysis in which we searched the key words “Sustainability”, “Sustainable Development”, “Education for Sustainable Development” and “Nature-Society Studies” in the Module Regulations. Our data indicate great heterogeneity between the degree programs. The key words were predominantly found in majors in “Human Geography”, “Geography” and teacher training programs for “academic high schools”. Aspects of the results considered in the paper include: (a) differences in the orientation of degree programs, (b) varying degree of implementation in the modules, (c) different conceptual understanding of the principles of sustainability, (d) the extent to which concepts of Environmental Education and Education for Sustainable Development are mixed, (e) heterogeneity between mandatory courses and electives.     

Tobacco,Eurasian Trade,and the Early Modern Iranian Economy

This article focuses on the development of the tobacco industry in Iran during the seventeenth and eighteenth centuries. It uses this discussion as an entry point to inquire about the early modern Iranian economy. Using a wide range of primary and secondary sources, it makes several historiographical interventions. In explaining what the development of a completely new agrarian industry means in Iranian society, the paper suggests that innovation and intensification may not have been completely absent in agriculture and that in contrast to the way some of the available literature tends to argue, the Iranian economy may not have experienced continuous decline in all sectors throughout the seventeenth and eighteenth centuries. In addition, this article contends that the tobacco industry helped bring about the rise of merchants and landowners in Iranian society, and with that the further development of mass consumption and ever-increasing cycles of production and accumulation that expanded the commercialization of agriculture, domestic and international trade networks, and Iran's agrarian economy.
