Ex situ conservation of plant genetic resources: global development and environmental concerns.

Conservation of plant genetic resources is achieved by protection of populations in nature (in situ) or by preservation of samples in gene banks (ex situ). The latter are essential for users of germplasm who need ready access. Ex situ conservation also acts as a back-up for certain segments of diversity that might otherwise be lost in nature and in human-dominated ecosystems.

The decision to hospitalize.

The authors explored determinants of psychiatric hospitalization in four Manhattan general hospital emergency rooms and found that although the nature and severity of a patient's problem played the most important role in the decision to hospitalize, the facility involved was also a determining factor. The findings are discussed in relation to policy concerning staffing and organization of emergency room services and future studies of service delivery in this area.

Disability, psychosomatic disease, and psychoneurosis. The problem of differential vulnerability.

A pattern of cognitive and of affective development characterizing three classes of psychiatric patients is presented: (1) disabled persons, usually unskilled laborers showing a 'somatization reaction', are unable to form abstract categories and, as well, to describe the physiological correlates of 'inner' feelings; (2) psychosomatic patients may show highly developed cognitive skills, although they may not; but they uniformly show a similar inability to 'know' and describe inner feelings; (3) 'neurotic' patients, most dramatically in the phobic category, often show both well-developed cognitive skills and a high degree of sensitivity to, and ability to describe, the symptom complex of anxiety in physiologically relevant forms, with maintenance of meaningful relations with supportive (often 'overprotectively' supportive) family members. These three different states can be diagrammed as follows: (1) -, -; (2) +/-, -; (3) +, +. The suggestion appears that these differences have to do with vulnerability, and that there may be in the general population three separable populations at risk for the development of these three categories of psychiatric disorder.

An evaluation of the nutritive value of new high protein oat varieties (cultivars).

Studies were conducted to evaluate the nutritive value of new high protein oat varieties using chicks and rats. Oat groats studied were Lodi, Dal, and Goodland; protein contents were 16.0, 18.

How are 'psychosomatic' patients different from 'psychoneurotic' patients?

Two groups of white male patients of the same racial stock were selected on the basis of their acceptance or rejection by psychiatric residents for extended treatment. The group of patients eagerly accepted were mostly college students with anxiety, several of a phobic type, while the completely rejected group was composed of rheumatoid arthritic patients. Examination of samples of verbal transcript material showed that previously determined criteria, established on the basis of content analysis of interview transcripts, place the arthritic patients very much in the 'unsuitable for psychoteraphy' category, whereas the selected patients were highly 'suitable'.
