| biomedical model | A conceptual model of illness that excludes psychological and social factors and includes only biological factors in an attempt to understand a person's medical illness or disorder. (05 Mar 2000) |
|---|---|
| biopsychosocial model | A conceptual model that assumes that psychological and social factors must also be included along with the biological in understanding a person's medical illness or disorder. (05 Mar 2000) |
| genetic model | A formalised conjecture about the behaviour of a heritable structure in which the component terms are intended to have literal interpretation as standard structures of empirical genetics. (05 Mar 2000) |
| mathematical model | <epidemiology> A formal framework to convey ideas about the components of a host-parasite interaction. Construction requires three major types of information: (a) a clear understanding of the interaction within the individual host between the infectious agent and the host, (b) the mode and rate of transmission between individuals, and (c) host population characteristics such as demography and behaviour. Mathematical models can aid exploration of the behaviour of the system under various conditions from which to determine the dominant factors generating observed patterns and phenomena. They also aid data collection and interpretation and parameter estimation, and provide tools for identifying possible approaches to control and for assessing the potential impact of different intervention measures. (05 Dec 1998) |
| catalytic model | <epidemiology> A (rather misleading name for a) type of compartmental model in which the force of infection is treated as a parameter to be estimated. (05 Dec 1998) |
| pathological model | An animal or animal stock that by inheritance or by artificial manipulation develops a disorder similar to some disease of interest and hence directly or by analogy furnishes evidence of its pathogenesis and may be used as a model for the study of preventive or therapeutic measures. (05 Mar 2000) |
| medical model | A set of assumptions that views behavioural abnormalities in the same framework as physical disease or abnormalities. (05 Mar 2000) |
| cloverleaf model | A model for the structure of tRNA; so named because the structure roughly resembles a cloverleaf. (05 Mar 2000) |
| model | 1. A representation of something, often idealised or modified to make it conceptually easier to understand. 2. Something to be imitated. 3. In dentistry, a cast. Origin: It. Midello, fr. L. Modus, measure, standard (05 Mar 2000) |
| Monod-Wyman-Changeux model | A model used to explain the allosteric form of cooperativity; in this model, an oligomeric protein can exist in two conformational states in the absence of the ligand; these states are in equilibrium and the one that is predominant has a lower affinity for the ligand (which binds to the protein in a rapid equilibrium fashion). Synonym: concerted model. (05 Mar 2000) |
| wax model denture | A setup of artificial teeth so fabricated that it may be placed in the patient's mouth to verify esthetics, for the making of records, or for any other operation deemed necessary before final completion of the denture. Synonym: wax model denture. (05 Mar 2000) |
| collisionless plasma model | <radiobiology> Model of a plasma in which the density is so low, or the temperature so high, that close binary (two-body) collisions have practically no significance (on certain timescales) because the time scales of interest are shorter than the collision time. Yields valid physical results for timescales much shorter than the average collision time in a real plasma. (09 Oct 1997) |
| compartmental model | <epidemiology> A mathematical model which divides hosts into different compartments according to their infectious state. A typical model for microparasites might be an SEIR model. Sometimes referred to as a prevalence model. (05 Dec 1998) |
| computer model | A mathematical representation of the functioning of a system, presented in the form of a computer program. Synonym: computer simulation. (05 Mar 2000) |
| concerted model | A model used to explain the allosteric form of cooperativity; in this model, an oligomeric protein can exist in two conformational states in the absence of the ligand; these states are in equilibrium and the one that is predominant has a lower affinity for the ligand (which binds to the protein in a rapid equilibrium fashion). Synonym: concerted model. (05 Mar 2000) |
