A constraint based assignment system for protein 2D nuclear magnetic resonance

Leishman, Scott January 1995 (has links)
The interpretation of Nuclear Magnetic Resonance (NMR) spectra to produce a 3D protein structure is a difficult and time consuming task. The 3D structure is important because it largely determines the properties of the protein. Therefore, knowledge of the 3D structure can aid in the understanding of its biological function and perhaps lead to modifications which have an enhanced therapeutic activity. An NMR experiment produces a large 2D data spectrum. The important part of the spectrum consists of thousands of small cross peaks and the interpretation task is to associate a pair of hydrogen nuclei with each peak. Manual interpretation takes many months and there is considerable interest in providing (semi-) automatic tools to speed up this process. The interpretation is difficult because the number of combinations can quickly swamp the human mind and the spectrum suffers from peaks overlapping and random noise effects. ASSASSIN (A Semi-automatic Assignment System Specialising In Nmr) is a distributed problem solving system that has been implemented in the identification of peaks associated with the hydrogen nuclei at the end of long side chains. These results are then passed onto the structural assignment stage. The structural assignment stage is a feedback loop which involves the interpretation of a spectrum and the generation of preliminary structural models. These models can then be used to simplify further analysis of the spectrum. ASSASSIN uses a constraint manager implemented in CHIP to analyse this data more quickly and thoroughly than a human. The results of this work reveal that a constraint based approach is well suited to the NMR domain where the problems can be easily represented and solved efficiently.

Creativity, openness to experience, and environmental support in problem solving

Weakland, Marie A. January 1999 (has links)
The relationship between the personality trait of openness to experience and problem solving ability in environments offering various levels of informational support in the form of analogous problems was investigated using 173 participants. I suspected the strongest positive relationship in an environment offering moderate support and that individuals who were high on openness to experience would be likely to see that previous presented information was analogous in nature. There was no relationship between penness to experience and problem solving ability as a function of the environment or in general. However, students given a high level of support solved significantly more problems than those participants receiving no support. Also, more students solved the problems when they saw an analogous connection between the experimental and the demonstration problems. An implication may be that problem solving ability can be taught using analogies, if the information is complete and students are able to determine the relevance to future problems. / Department of Psychological Science

Clinical case similarity and diagnostic reasoning in medicine

Arocha, José F. (José Francisco) January 1991 (has links)
This thesis describes a study of novice problem solving in the domain of medicine. The study attempts to answer questions pertaining to the diagnostic accuracy, the generation and change of diagnostic hypotheses, and the use of clinical findings in the course of solving clinical cases with similar presenting complaints. Two specific issues are addressed: (1) how does the initial case presentation suggesting a common disease schema affect the diagnostic problem solving process of novices and intermediate subjects? (2) what are the processes the subjects used in coordinating hypothesis and evidence during diagnostic problem solving? / Medical trainees (students and a resident) were given four clinical cases to solve and think-aloud protocols were collected. The verbal protocols were analyzed using methods of protocol analysis. The results show that second year medical students interpreted clinical cases in terms of the more common disease schema, regardless of the initial presentation of the case. More advanced students, although unable to make a correct diagnosis in most instances, were less susceptible to such confusions. Only the resident was able to interpret the cases in terms of different disease schemata, reflecting knowledge of the underlying disease process. The semantic analysis of the protocols revealed that most students, especially at lower levels of training, misinterpreted or ignored the evidence that contradicted their initial hypotheses and made use of a mixture of forward and backward reasoning; a finding consistent with previous research. Implications for educational training and for a theory of novice problem solving in medicine are presented.
