Context Mediation is a field of research that is concerned with the interchange of information across different environments, which provides a vehicle to bridge semantic gaps among disparate entities. Knowledge Discovery is concerned with the extraction of actionable information from large databases. A challenge that has received relatively little attention is knowledge discovery in a highly disparate environment, that is multiple heterogeneous data sources, multiple domain knowledge sources and multiple knowledge patterns. This thesis tackles the problem of semantic interoperability among ...

"This study is an early evaluation of the benefits of using the internet and information technology for Human Resources programs and practices by a sample of large public and private for profit and not for profit organizations. The respondents themselves were higher in transformational leadership. Additionally, those with higher transformational scores were more likely to use IT for Human Resources Management. The use of IT enhanced accessibility, timeliness, and HR decision making. We are likely to see in the years to come many more evaluated shifts of HR programs and practices from...

(Complete work in Spanish) Remote sensing aerial spectral imaging was one of the first application areas where spectral imaging was used in order to identify and monitor the natural resources and covers on earth surface. Aerial spectral imaging is being developed with the aim of monitoring natural resources like coastal areas, forestry and extensive crops. The information contained in hyperspectral images allows the reconstruction of the energy curve radiated by the terrestrial surface throughout the electromagnetic spectrum. Hence, the characterization, identification and classification of th...

The purpose of this book was to describe the variables that contributed to the establishment of a charter school in an urban Arizona and rural California school district, noting the similarities and dissimilarities and disclosing the factors used to justify implementation of the Montessori theory of education. The secondary purpose of this book was to describe the guidelines for maintaining a charter school, the evaluation methods and factors used in the school’s unique experience with staff development. The two schools experienced many similarities when the same variables were applied to bot...

The diversity of stellar death is revealed in the energy, velocity and geometry of the explosion debris ("ejecta''). Using multi-wavelength observations of gamma-ray burst (GRB) afterglows I show that GRBs, arising from the death of massive stars, are marked by relativistic, collimated ejecta ("jets'') with a wide range of opening angles. I further show that the jet opening angles are strongly correlated with the isotropic-equivalent kinetic energies, such that the true relativistic energy of GRBs is nearly standard, with a value of few times 10^51 erg. A geometry-independent analysis whic...

Driven to improve their competitive advantages, manufacturers are looking to electronic supply chain collaboration (ESCC). The benefits of ESCC have long been described in the literature, but only recently, after considerable advances in the capability of information technology, have these benefits been verified by empirical studies. The high cost of ESCC has limited its early application to larger companies. Although interest in ESCC is high in business and information systems circles, the large group of small manufacturers has received meager attention. Theory suggests, however, that ESCC be...

Cross Language Text Retrieval (CLTR) has been defined as the retrieval of documents in a language different from that of the original query. To make this possible some kind of mechanism has to be applied in order to translate the information contained in the source sentence. Many different approaches have been carried out with the purpose of transferring the information from the source language query to the target language one. Though all these methods deal with a way of translating as much information as possible from the source query, little research has been conducted in relation to the fie...

(Note: Dissertation is written in Spanish.) The principal aim of this thesis is to discover the origin, formulation and effect of what is known as a “strategic behaviour”. A very well-known type of strategic behaviour is the persuasive behaviour, the purpose of which is to produce changes in the ideas, behaviour or feelings of a person. The corpus chosen for analysis has been one made up of five parliamentary sessions which preceded and followed the 1988 Education Reform Act. This acts represents the most important governmental initiative in the education service of England and Wales si...

This thesis dissertation, written in Spanish, presents a new model for the linguistic specification and the computational management of man-machine dialogues following commands issued in spoken natural language. Our aim is to design and implement a conversational system for the automatic telephone task scenario, namely Delfos. Voice dialing represents a current trend in research, the purpose of which is to provide functional systems for products ranging from domestic appliances such as a video or a washing machine to more sophisticated environments such as a complete house, with an interface i...

Concerns over potential impediments to biochemical patenting derive from the significance of biotechnology to the future of medicine. From a medical perspective, developments in genetics could hardly be more consequential. (10) The legal revolution referenced above began with a scientific breakthrough--the development in 1972 of recombinant DNA technology. This invention spawned further advancements in genetic research, including the discovery in 1983 of a generally applicable method for cloning genes for polypeptides where the amino acid, DNA, and mRNA sequences were not completely known; the...
