Aspects of written language production over adult life.

Self-descriptions written by adults were analyzed to explore the effects of age, gender, vocabulary, nonverbal intelligence, and educational-occupational status on lexical aspects of language and grammatical complexity. Multivariate analyses indicated that, after controlling for other background variables, age had a significant effect on vocabulary diversity, sentence complexity, subordinating conjunctions, and possibly sentence length. Four variables--word output, word length, long words, and readability--were affected mainly by vocabulary and educational-occupational status. An unexpected and small but significant gender difference in the readability of the descriptions was observed across all age groups.

The idea of ageing: an historical and psychological analysis.

The idea of ageing can be traced back to the earliest written records. Prescientific beliefs were governed by animistic forms of thought leading to attempts to control ageing, disease and death through magic and supernatural agencies. The idea of ageing was gradually elaborated in Greek and Roman medicine and incorporated into religious beliefs and social practices. Ideas from the classical period were revived during the Renaissance, but modern scientific approaches to ageing did not emerge clearly until the 17th century, with systematic medical and statistical inquiries into the causes of death, and later, in the 19th and 20th centuries, into the biological mechanisms of ageing. The idea of an 'elixir of life' has been all but totally abandoned, although increases in the average length of life are expected to continue for some time. Refinements in the idea take account of the social and behavioural aspects of ageing.

Axial filament involvement in the motility of Leptospira interrogans.

Motility mutants of Leptospira interrogans serovar illini were isolated and analyzed by dark-field and electron microscopy. Mutants were obtained by screening for small colonies after nitrosoguanidine treatment. One class of mutants did not have hook- or spiral-shaped ends. In addition, the axial filaments from these mutants were not coiled. An analysis of revertants of two of the mutants in this class indicated that the mutations were pleiotropic with respect to motility, hook- and spiral-shaped ends, and axial filament coiling. We conclude that the axial filaments and the hook- and spiral-shaped ends are involved in L. interrogans motility.

Geriatrics in relation to the social and behavioural sciences.

Social and behavioural gerontology is the scientific study of how men and women adapt to their environment as they grow older. It is a multidisciplinary area, comprising subjects each of which asserts an existence in its own right, as a scientific enterprise, apart from other subjects in the area, and apart from geriatrics. Social and behavioural gerontology, however, forms part of the total context within which geriatrics gets its meaning and value. Geriatrics, in turn, affects these other adjacent disciplines. Social and behavioural gerontology could help in a general way by putting geriatrics into this wide perspective and thus demonstrating the wider issues that might otherwise be neglected in the busy round of geriatric care. Social and behavioural gerontology could also help in numerous particular ways such as: the collection of normative data; improved conceptual analysis; better methods of observation, experimentation, measurement and data analysis; the integration of social and behavioural case-work with clinical geriatrics for both treatment and training purposes; improved techniques of social and behavioural assessment; improvements in communication; better social attitldes; increased self-help and understanding of the role of the elderly in society; more effective consumer behaviour; and more effective social policies incorporating long-range, broad-spectrum preventive measures.
