  • We investigate the potential of Tree Substitution Grammars as a source of features for native language detection, the task of inferring an author’s native language from text in a different language. We compare two state of the art methods for Tree Substitution Grammar induction and show that features from both methods outperform previous state of the art results at native language detection.

  • This paper investigates conceptually and empirically the novel sense matching task, which requires to recognize whether the senses of two synonymous words match in context. We suggest direct approaches to the problem, which avoid the intermediate step of explicit word sense disambiguation, and demonstrate their appealing advantages and stimulating potential for future research.

  • This paper doesn’t outline how to measure and report social sustainability. This task has already been undertaken by the author and presented elsewhere (see Kimmet and Wikstrom 2005). The much less ambitious objective of shoring up the case for such measurement frameworks is all that’s attempted here. Arguably though, this is at least as important as how to do it, given that many real estate investors will want to evaluate potential investments in their own way once it is clearly understood what social sustainability is, and why it should be taken seriously. ...

  • Countries around the world are adopting the practice of using waste products and other alternatives to replace fossil fuels in cement manufacturing. Industrialized countries have over 20 years of successful experience (GTZ and Holcim 2006). The Netherlands and Switzerland, with respective national substitution rates of 83% and 48%, are world leaders in this practice (Cement Sustainability Initiative 2005). In the US, it is common for cement plants to derive 20-70% of their energy needs from alternative fuels (Portland Cement Association 2006).

  • Overall, the microfinance sector is continuing to expand despite tremendous operating obstacles in serving the market in a sustainable way. The lack of access to financial services for households and micro and small enterprises is quite striking in Africa and microfinance institutions are crucial in responding to the unbanked segments. However, the microfinance sector is still relatively small and weak compared to other global regions and despite the huge potential market. In this context, the role of savings banks in microfinance should be recognised and boosted.

  • O UR GUEST editors have assumed the additional role of guest authors for this issue on the topic of Cardiovascular Nuclear Medicine. They have performed equally well, clearly defining the role of pharmacological stress testing in the assessment of cardiovascular disease. This alternative to standard treadmill exercise is achieving increased application with the availability of several agents that have significantly different pharmacological actions.

  • New approaches to tailor-made cellulose/starch/lignin-synthetic polymer graft copolymers with precise control over molecular weight, degree of substitution, backbone-graft linkage, and the overall grafting process are being studied. Cross-linked graft copolymers with exactly defined polymer chain segments between crosslink points have been prepared. The graft copolymers exhibit a two-phase morphology and can function effectively as compatibilizers/interfacial agents to alloy cellulosic and lignocellulosic materials with synthetic polymers.

  • The substitution of processes can be applied on a fundamental basis, for example, substitution of airless spray for conventional spray equipment can reduce the exposure of a painter to solvent vapors. Substitution of a paint dipping operation for the paint spray operation can reduce the potential hazard even further. In any of these cases, the automation of the process can further reduce the potential hazard (Table 74.5). 74.7.

  • Chemical reactions (abiotic reactions) are “classical” chemical reactions that are not mediated by bacteria. They may include reaction processes such as precipitation, hydrolysis, complexation, elimination, substitution etc. that transform chemicals to other chemicals and potentially alter their phase/state (solid, liquid, gas, dissolved). Precipitation is the removal of ions from solution by the formation of insoluble compounds, i.e. a solid-phase precipitate. Hydrolysis is a process of chemical reaction by the addition of water.

  • Equating the total energy at the start and end (potential and kinetic) yields: (6.66) which is a quadratic in * and can be rearranged as follows: (6.67) Given the values of W = 5 lbs, h = 3.0 feet and k = 20 lbs/ft, *S = 5/20 = 0.25 ft. Substituting this in the above equation gives for the maximum deformation * = 1.5 feet or 6 *S. 6.5.2.2 Drop Test Using a Spring Having Finite Weight Let us repeat the drop test, but now assume that the bar has appreciable mass, Wb, as shown in Fig. 6.41.

  • We now turn to the potential benefits of having a more accurate estimate of Chemical A's true cost. As described above, this requires knowledge of the firm's ability to change its actions in response to better information. If the disposal cost X of Chemical A is revealed to be significant, how might the firm respond? This is a question that hinges primarily on the firm's technological options and the availability of substitute inputs. Substitutes can take a variety of forms.

  • The aforementioned water scarcity problems, water quality problems, and climate-related impacts will be a major challenge to businesses in the years ahead. It is increasingly clear that the era of cheap and easy access to water is ending, posing a potentially greater threat to businesses than the loss of any other natural resource, including fossil fuel resources. This is because there are various alternatives for oil, but for many industrial processes, and for human survival itself, there is no substitute for water.
