Discussion of: Foundation design for gravity retaining walls under earthquake by M. J. Pender
No full textThe discussers read the paper by Pender (2018) with great
interest. The author addresses the important issue of computing the pseudostatic critical acceleration of gravity/cantilever
retaining walls, corresponding to which a plastic mechanism is
activated within the soil–structure system and the wall starts
to move under the applied earthquake. In fact, the critical
acceleration is the key ingredient for the seismic design of
these structures, controlling both the maximum internal
forces and the final displacement (Conti and Caputo, 2018;
Conti et al., 2013)
Environmental indicators for the urban environment : a literature review
No full textA vast body of literature exists on the genesis and evolution of environmental indicators of all varieties. This document attempts to track the somewhat complicated progress of urban environmental indicators, where they are in usage and to what avail. It also emphasises the search to narrow down the range of 'ideal' indicators. The literature suggests that as experience and practice with indicators grows both in Ireland and world-wide the key set of urban environmental indicators can help policy makers and the public track sustainability issues more effectively. Indicators thus have a valuable role to play in the future of sustainable planning for urban areas.European Regional Development Fund through the Operational Programme for Environmental Services 1994-199
Rice research, technological progress, and impacts on the poor: the Bangladesh case (summary report)
No full text"This case study builds on an ongoing large-scale quantitative research project undertaken by BIDS/IRRI since 1987 originally in 64 unions from 57 districts of the country. It adds a qualitative research component to examine the impact of modern rice varieties (MVs) on livelihoods in a structured sample of eight of these villages across a range of favorable and unfavorable contexts..... The quantitative research shows that for households with access to land there have been direct adoption impacts in the form of increased yields and higher profits. However, since rice now only represents around 20 percent of most households' overall income, nonagricultural income is found to have gained dramatically in importance for rural households. While the profitability has declined over time, rice contributes to improved food security and provides a “springboard” for both rich and poor farm households moving into nonfarm income generation and employment... The qualitative research component generally confirmed these general findings, highlighting other factors such as the improved status associated with fixed-rent tenancy and “contract” labor arrangements. The qualitative research also shows negative adoption impacts such as shrinking common property resources (wild fish, vegetables, etc., and declining soil fertility, both of which may increase the long-term vulnerability of the poor. It also throws light on the processes of technology dissemination.... It was found that the linking of qualitative and quantitative research methodologies was useful in (a) generating complementary data of different kinds on similar issues and (b) generating new data missed within a purely quantitative approach. The sustainable livelihoods framework was a useful, flexible tool for structuring the qualitative data collection and analysis. However, the research study as a whole was limited by the fact that the qualitative component was “bolted onto” a quantitative study already underway. Therefore the framework, and the various data collection methodologies, were not systematically integrated across both components of the study. In conclusion, future agricultural research on rice may need to further address the question of MV adoption potential on risk-prone lands, the relevance of existing technology dissemination systems, the relationship between MV adoption and crop diversification, and the challenges of more sustainable crop management techniques."

No full textBank Panics, Golden Grains, and Gold Standards: Essays on North American Macroeconomic History
No full textThis dissertation is the culmination of three research projects on North American Macroeconomic History. The first two Chapters analyze the effects of deflation on the financial sector and the real economy. Chapter 1 looks at the U.S. experience between 1868 and 1913, and Chapter 2 looks at the Canadian experience between 1867 and 1913. The 3rd Chapter also looks at Canada between 1876 and 1913, but instead of inflation, it examines the "Wheat Boom" and attempts to gain a new understanding of its nature, cause, and scale. Chapter 3 also offers a preliminary discussion on how the Wheat Boom is related to the historical mistreatment of Indigenous peoples in Canada. Combined, these three works used a mixture of econometric techniques, data analysis, analytic narrative, and a little bit of modeling, to better understand North America's economic history pre-1913

Measuring the possibilities of interfuel substitution
No full textWhat are the costs of making consumption of production activities use less-polluting fuels? The author reviews how the fuel mix used by different industries has changed over time and examines 2 techniques for estimating the responsiveness of fuel demand to fuel prices: econometric models and the engineering approach. With econometric models, the elasticity of substitution between energy and other inputs determines the costs of making activities less energy-intensive, while the elasticity of substitution between sources of energy (interfuel substitutability) determines the marginal costs of replacing one energy source with another. The engineering approach uses more detailed technical information and can draw a more complete picture, but with less ability to inform about activities with a vast number of different economic agents. Among the author's main conclusions: There are surprisingly large variations in energy and fuel use over time and between countries. Industrial output increased 62 percent in OECD countries between 1971 and 1988, for example, while energy use stayed unchanged. Also, shares of energy sources for industry and electricity vary greatly with local availablity, indicating that these sectors have some flexibility in choice of energy source. A judgment on whether this variability indicates that an economy responds cheaply if energy prices are changed selectively depends on how one reads the more detailed studies in the econometric and engineering literature. Lack of data is the biggest problem in estimating fuel and energy substitutability in non-OECD countries. Engineering studies of fuel switching in industry are rarely available. They exist, however, for the power industry and could be used to estimate the costs of alternative fuel-mixes for particular greenfield sites. The technique could not be used for assessment of economywide policies. Econometric studies are useful inasmuch as they take a sector- or economywide perspective. Econometric techniques are challenging, but often represent the state of the art in providing reliable estimates for elasticies of substitution - particularly when data are scarce and the level of aggregation is high. The issue of whether econometrically estimated structural parameters can be transferred across borders has not been thoroughly investigated.Oil Refining&Gas Industry,Transport and Environment,Energy and Poverty Alleviation,Energy and Environment,Airports and Air Services
