Urban CO2 Planning: A Decision Support System
No full textPatterns of urban development affect flows of material and energy within urban settlements and exchanges with their surroundings. In recent years the quantitative estimation of the components of the so-called urban metabolism has increasingly attracted the attention of researchers from different fields. To contribute to this effort we developed a modelling framework for estimating carbon exchanges in relation to alternative land-use scenarios. The framework bundles three components: (i) a Cellular Automata model for the simulation of the urban land-use dynamics; (ii) a transportation model for estimating the variation of the transportation network load and (iii) the ACASA (Advanced Canopy-Atmosphere-Soil Algorithm) model tightly coupled with the mesoscale weather forecasting model WRF. We present and discuss the results of an example application on the City of Florence
AN ANALYSIS OF VALUE-ADDED AGRICULTURAL EXPORTS TO MIDDLE-INCOME DEVELOPING COUNTRIES: THE CASE OF WHEAT AND BEEF PRODUCTS
No full textThis study determined probable future directions in U.S. value-added agricultural exports to middle-income developing countries (MIDCs) under the assumption of continued income growth. Import share equations for U.S. bulk, semi-processed and value-added wheat or beef products, as a percent of total U.S. wheat or beef product exports to each MIDC, were econometrically estimated using the ordinary least squares (OLS) technique. The empirical results indicate that in most MIDCs, increases in real per capita income have negative effects on the import share of processed wheat products while having positive effects on the import share of bulk wheat. However, import shares of U.S. processed beef products are likely to increase with income growth in most MIDCs.International Relations/Trade,
Explicating the Face Perception Network with White Matter Connectivity
No full textA network of multiple brain regions is recruited in face perception. Our understanding of the functional properties of this network can be facilitated by explicating the structural white matter connections that exist between its functional nodes. We accomplished this using functional MRI (fMRI) in combination with fiber tractography on high angular resolution diffusion weighted imaging data. We identified the three nodes of the core face network: the "occipital face area" (OFA), the "fusiform face area" (mid-fusiform gyrus or mFus), and the superior temporal sulcus (STS). Additionally, a region of the anterior temporal lobe (aIT), implicated as being important for face perception was identified. Our data suggest that we can further divide the OFA into multiple anatomically distinct clusters - a partitioning consistent with several recent neuroimaging results. More generally, structural white matter connectivity within this network revealed: 1) Connectivity between aIT and mFus, and between aIT and occipital regions, consistent with studies implicating this posterior to anterior pathway as critical to normal face processing; 2) Strong connectivity between mFus and each of the occipital face-selective regions, suggesting that these three areas may subserve different functional roles; 3) Almost no connectivity between STS and mFus, or between STS and the other face-selective regions. Overall, our findings suggest a re-evaluation of the "core" face network with respect to what functional areas are or are not included in this network. © 2013 Pyles et al

An economic evaluation of logging road maintenance
No full textThis thesis describes the results of a project conducted to determine the economics of forest road maintenance alternatives
between periods of timber harvesting. An open road and a closed road alternative will be compared to the economics of clearcutting an
entire area and obliterating the road system until reentry at the end of the rotation. Road maintenance data was collected from the
Siuslaw and Willamette National Forests in Oregon. An average present value cost per mile was determined for each location for U.S. Forest Service level one and level two maintenance. Level one is the maintenance performed on a road that is closed to vehicular traffic. Level two is the maintenance performed on roads open to high ground clearance vehicles. Reconstruction costs before each reentry were also included in the present value calculations. Results show that for short-term reentry periods, it is economically better to leave road systems open and maintain at level two than it is to close the roads and maintain at level one. The third alternative of clearcutting and obliterating the system until the end of the rotation was by far the best economic alternative. Only costs for actual maintenance were included in the analysis. Administrative costs, and costs associated with other resource values were not
considered. To help demonstrate how maintenance costs compare to total timber revenues, road maintenance costs for different road densities were compared to associated timber value. Road densities per section (640 acres) for different logging systems were used to calculate a present value road maintenance cost per section. This was compared to timber values per section for three different volume per acre figures. These volumes represented site classes II, III and IV. It was found that road maintenance and reconstruction make up a small percentage of the total timber revenue. Although the percent of total revenue was low, road maintenance appears to be a significant investment
