  • We present a novel model to represent and assess the discourse coherence of text. Our model assumes that coherent text implicitly favors certain types of discourse relation transitions. We implement this model and apply it towards the text ordering ranking task, which aims to discern an original text from a permuted ordering of its sentences.

  • The powders of Mg(Al1-xEux)2O4 have been synthesized by sol-gel method. Optical properties of the material were investigated. The nature of lines in luminescence spectra is related to the electron transitions of Eu3+ ions corresponding to different sites in the lattice. The influence of Eu concentration on optical spectra was studied.

  • This paper describes a novel event-matching strategy using features obtained from the transitive closure of dependency relations. The method yields a model capable of matching events with an F-measure of 66.5%. training and test instance in a feature space. Conceptually, our features are of three different varieties. This section describes the first two kinds, which we call “low-level” features, in that they attempt to capture how much of the basic information of an event e is present in a sentence s. 2.1 Lexical features ...

  • The metastable state of liquids which are supercooled has been the subject of interest for over 300 years. Supercooled water and aqueous solutions are found in the atmosphere, in cold-hardy organisms, and in many industrial applications. For example, freeze tolerance and the associated avoidance of supercooling, is the dominant cold-related strategy in Southern Hemisphere insects, being found in 77% of cold hardy insects. In industry, thermodynamic systems such as cool boxes have a significant financial driving force for supercooling to be controlled and this is also covered in this book...

  • The environmental industry is changing, along with the way it manages data. Many projects are making a transition from investigation through remediation to ongoing monitoring. Data management is evolving from individual custom systems for each project to standardized, centralized databases, and many organizations are starting to realize the cost savings of this approach.

  • Depending on their structures, polyphenols (e.g. tea polyphenols) could also act by chelating prooxidant transition metal ions such as Fe2+, which are involved in reactions eliciting free radical production, including hydroxyl radicals (OH•) and alkoxyl radicals (RO•) (Dufresne & Farnworth, 2001).

  • There is hardly any book that aims at solving problems typically encountered in the laser field, and this book intends to fill the void. Following some initial exercises related to general aspects in laser physics (Chapt. I), the subsequent problems are organized along the following topics: (i) Interaction of radiation with matter either made of atoms or ions, weakly interacting with surrounding species, or made of more complicated elements such as molecules or semiconductors (Chapters 2 and 3). (ii) Wave propagation in optical media and optical resonators (Chapters 4 and 5)....

  • But with other POPs the transition to safer alternatives will require more effort. Alternatives may be more expensive and their manufacture and use more complicated. That could put developing countries in an awkward spot – struggling from day to day, the world's poor tend to use what they can afford and what is available. So it is not enough for the Convention simply to say No to its target list of POPs: It must also help governments find a way to say Yes to replacement solutions. Take the case of DDT.

  • Workman’s background as a trailer-maker convinced him that “you could capture the essence of a memorable film in as little as a single shot—if you chose the shot carefully enough.” (Birchard, 91) His assemblage of these “essences” places images together for broad generic or thematic reasons, as well as on the basis of simple physical resemblance (similar shots of darting eyes, people popping bubble-gum) or gag value (one clip finishing a sentence from another).

  • In implementing a programme of privatisation and restructuring, it should be recognised that the restructuring process, if left solely to the market forces, may create substantial unemployment and incur considerable social costs. Supporting a programme of careful restructuring by the creation of new business out of the old, engaging under-utilised assets, with or without an element of public subsidy, may add considerable value to local economies. The experience of the transitional economies in Europe shows the potential for creating small businesses out of large company restructuring.

  • Haugeland (1998) eloquently describes the relation between mind and world as one of intimacy, a ‘commingling’ or ‘integralness’ of mind, body, and world. Cognition depends as much on aspects of the agent’s environment as on the agent’s inherent properties. Because it is the joint effect of these properties that control cognition, their contributions to individual cognitive processes cannot be considered one by one.

  • Obviously, in this case we cannot fully eliminate the identification and causality problem because firms’ profits/losses may affect their demand for credit as well. In order to circumvent this problem (at least partly) we use in addition an interaction variable between the profitability dummy and the lagged value of the access to credit variable. The rationale is to test whether long-term enterprise-bank relations are associated with the firm’s viability.

  • Unfortunately, the information on SME lending is very fragmentary. According to the Banca d’Italia (1999: 180), the share of loans to small businesses increased until the early nineties, but then contracted until 1998. 5 In recent years, SME lending has increased at a more rapid pace than lending to other firms (Banca d’Italia 2003, 2004). Hence, the evolu- tion of SME loans in the 1990s may have been a transitional problem.

  • Moreover, the residential location choices of low-skilled workers are likely to be geographically constrained by zoning restrictions limiting the location and quantity of low-income housing. Such constraints may limit the ability of low-skilled workers to choose residential locations within reasonable public-transit commutes of important employment centers. In light of these considerations, it is not surprising that researchers have found large differences in employment rates between car-owners and non car-owners. ...

  • With regard to English passage comprehension, the children initially instructed in Spanish and transitioned into English at the end of second grade made the most gains between the end of second grade and the end of fourth grade. At the end of fourth grade, the monolingual English-speaking students had the highest scores, followed by the Spanish-speaking English-instructed students, Spanish-speaking students transitioned at the end of second grade, and Spanish-speaking students transitioned at the end of third grade.

  • This textbook on Political Economy, prepared by the Economics Institute of the Academy of Sciences of the U.S.S.R., was first published in the U.S.S.R. in 1954. Regarding political economy as the science of the laws of development of the relations of production in human society, it deals not only with the capitalist economic system but also with pre- capitalist economic relations and, in considerable detail, with the economics of socialism.

  • Along with providing more realistic views of ecosystem service provision and use, these flow maps can also enable improved value transfer. A better understanding of the relative strength of flow can identify regions more likely to provide higher or lower levels of value (Boyd and Wainger 2003). Indeed the flow of benefits is the only quantity that relates supply and demand and is a natural candidate for a quantitative statement of value. In order for a flow of benefit to exist, a potential for provision must coexist with a need for use; the marginal value is determined by the “difference...
