Geographical variations in mortality: an exploratory approach
No full textThis thesis aims to provide a geographical contribution to the understanding of disease causation, primarily through the development of causal models of chronic disease mortality incorporating both the physical and social environments. The overwhelming impression of previous research in this field is one of conflicting findings. For example, studies examining the relationship between disease and water hardness have found positive relationships, negative relationships and no relationship whatsoever. It is contended that this failure to replicate results is a direct consequence of applying an unsuitable 'confirmatory' approach to the quantitative analysis of geographical data. It is argued also that it is necessary to adopt a more appropriate statistical methodology, that of 'exploratory' statistics, before progress can be made. After an exegesis of the exploratory approach, the commonly used technique of multiple regression is given an exploratory interpretation. Each of the assumptions of this technique is discussed, and attention focuses on the effects of breaking the assumptions and on methods of detecting and overcoming the resultant problems. This exposition is illustrated by the re-analysis of previous studies, and it is demonstrated that inappropriate methods have led some researchers to inferential error. Finally in this methodological part of the research, an examination of the analysis of ratios is undertaken; here too it is suggested that the inappropriate analysis of death rates has resulted in some researchers making incorrect inferences.The empirical aspects of the thesis centre on the analysis of mortality variations in England and Wales. A critical appraisal of previous studies of the relationship between disease and water hardness is undertaken, and it is concluded that quantitative techniques have been poorly applied. Exploratory data analysis is then employed to develop models accounting for geographical variations in mortality experienced by the County Boroughs of England and Wales. In contrast to previous studies that have analysed these variations, no strong relationship is found between disease and water hardness. Moreover, an examination of the mortality experiences of Boroughs whose water supply has changed substantially over time also results in the conclusion that the effects of water hardness have been overestimated. Finally, the study examines the difficult problem of drawing inferences from aggregate data. Although it is concluded that much work remains to be undertaken, it is again argued that the exploratory approach may allow progress to towards the solution of this problem and, consequently, some guidelines for further research are outlined

Language Engineering in Grammatical Framework (GF)
No full textThis thesis describes a number of practical experiments rather than theoreticalinvestigations in the area of natural language processing. The basis forthe work presented is Grammatical Framework (GF). It is a very complexsystem, which comprises among other things a grammar formalism based ontype theory and its implementation written in Haskell. GF is intended forhigh-quality machine translation (of INTERLINGUA type) in the restrictedlanguage domains.The primary concern of this thesis is however limited to the usage of GFas a piece of software. The main results are: Implementing a syntax editor, which provides a graphical user interface(GUI) for the command-line GF core. Writing a part of code for automatic generation of gramletspure Javaprograms with limited (compared to GF) functionality that can be runon PDA (Portable Device Assistants) and as applets in a browser. Writing the Russian resource grammar that takes care of the most basicmorphological and syntactic rules and serves as a standard libraryfor building application grammars (describing restricted language domains)in Russian.These results contribute to language engineering in GF on two differentlevels: Author level (end-user) constructing sentences in natural languages. Grammarian level building a grammar description, which is laterused on the author level.The last part of the thesis deals with a non-linguistic domain. In thatexperiment we try to apply functional parsing technique to the well-knownproblem of protein secondary structure prediction (bioinformatics)

Language Engineering in Grammatial Framework (GF)
No full textThe basis for the work presented is Grammatical Framework (GF)a grammar
formalism based on type theory. It is also a powerful language processor
that provides a convenient framework for various multilingual applications.
The primary concern of this thesis is the usage of GF as a piece of software.
The main results are:
Implementing a syntax editor, which provides a graphical user interface
(GUI) for the command-line GF core.
Writing the Russian resource grammar that takes care of the most
basic morphological and syntactic rules and serves as a standard library
for building application grammars (describing sublanguage domains) in
Russian.
These results contribute to language engineering in GF on two different
levels:
Author level (end-user)constructing documents in natural languages.
Grammarian level building a grammar description, which is later
used on the author level. One can also distinguish between application
and resource grammars. An application grammar focuses of a particular
sub-language domain, while resource grammar is a general-purpose
grammar that forms a basis for application grammars
