| population growth | <epidemiology> Increase, over a specific period of time, in the number of individuals living in a country or region. (12 Dec 1998) |
|---|---|
| population pyramid | <epidemiology> Graphical representation of the age and sex composition of a population, constructed by computing the percentage distribution of the population in each age and sex class. (05 Mar 2000) |
| population surveillance | <epidemiology> Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy. (12 Dec 1998) |
| suburban population | The inhabitants of peripheral or adjacent areas of a city or town. (12 Dec 1998) |
| synchronous cell population | <cell culture> A culture of cells that all divide in synchrony. Particularly useful for certain studies of the cell cycle, cells can be made synchronous by depriving them of essential molecules, which are then restored. Synchronisation breaks down after a few cycles, however, as individual cells have unique division rates. (19 Jan 1998) |
| q in population genetics | The frequency of the less common of two different alternative (allelic) versions of a gene. (the frequency of the more common allele is p). (12 Dec 1998) |
| topotypical population | <zoology> Population occurring at the type locality from which the type specimen was taken. (09 Jan 1998) |
| urban population | The inhabitants of a city or town, including metropolitan areas and suburban areas. (12 Dec 1998) |
| Bayley Scales of Infant Development | A psychological test used to measure the developmental progress of infants over the first two and one-half years of life; consists of three scales: mental, motor, and behaviour record. (05 Mar 2000) |
| bone development | Gross development of bones from foetus to adult. It includes osteogenesis, which is restricted to formation and development of bone from the undifferentiated cells of the germ layers of the embryo. It does not include osseointegration. (12 Dec 1998) |
| maxillofacial development | The process of growth and differentiation of the jaws and face. (12 Dec 1998) |
| child development | The continuous sequential physiological and psychological maturing of the child from birth up to but not including adolescence. It includes healthy responses to situations, but does not include growth in stature or size (= growth). (12 Dec 1998) |
| child development disorders, pervasive | Severe distortions in the development of many basic psychological functions that are not normal for any stage in development. These distortions are manifested in sustained social impairment, speech abnormalities, and peculiar motor movements. (12 Dec 1998) |
| personality development | Growth of habitual patterns of behaviour in childhood and adolescence. (12 Dec 1998) |
| pervasive development disorder | <neurology, psychiatry> A large group of developmental disabilities which are neurological disorders, usually of unknown cause. Characteristics include reduced abilities to understand language and communicate normally, reduced ability to socially interact with others in a normal manner, and limited variety in activities and interests. Individuals will also often respond in unusual ways to sensations, engage in repetitive activities, and resist changes to the environment or to daily routines. Types of pervasive development disorder include autism, Retts Syndrome, Hellers Syndrome, and Aspergers Syndrome. Acronym: PDD (12 Jan 1998) |
