The anatomy and pathology of the venous system of the leg has been, until very recently, a neglected subject. This is so, in spite of the fact that lesions resulting from diseases of these veins are among the commonest from which mankind suffers. To Homans (1917) must go the credit for awakening renewed interest in the subject, for he first clearly showed that the distressing ' ulcer and indura...

Several researchers (Burt, 1995; Marsden, 1982, 1983; Granovetter, 1973; Homans, 1951, 1974) have stressed the importance of actors who occupy strategic positions in social networks to explain aspects of diffusion processes in social structures: If contacts between two parties are only possible through a third party, the latter can be regarded as being in control of resource flows. Such transmi...

FusB-type proteins represent the predominant mechanism of resistance to fusidic acid in staphylococci and act by binding to and modulating the function of the drug target (elongation factor G [EF-G]). To gain further insight into this antibiotic resistance mechanism, we sought to identify residues important for the interaction of FusB with EF-G and thereby delineate the binding interface within...

The aim of this chapter is to review the available literature relating to the experience of health and health services of black women in Britain and to analyse the extent to which it adequately describes and contributes to an understanding of underlying concepts and perceptions of health and illness. Although there is a growing literature on the health experiences of black and minority ethnic w...

Objective: Lymphedema is the result of impaired lymphatic drainage from the affected organ. This abnormality can be primary or secondary. Different nonoperative and operative approaches have been introduced to treat chronic lymphedema. In this study, we describe a new surgical technique and compare its results with other more commonplace methods. Methods: Fifty-nine patients with the diagnosis ...

A common strategy for limiting the total annual catch in a fishery is to restrict entry and season length. We examine the results of this strategy when entry limitation amounts to a limit on capital, but fishing firms can vary an unrestricted input, and thereby use the restricted input more intensively. Under these regulatory constraints, fishing firmswill earn rents that depend on the elastici...

To the Editor: With scanning auger microscopy (SAM), a relatively new technique, one can obtain information on the chemical composition and bonding within the first few atomc layers of the surface in a solid material; and one can analyze for trace elements without damaging the specimen, a rare capability among measurement techniques. So far, the usefulness of the method has been demonstrated in...

Balance theory, a theoretical system developed by Cartwright and Harary to formalize concepts set forth by Heider, is used with slight modifications to restate fifty-six sociological and social-psychological propositions from the writings of Berelson, Lazarsfeld, and McPhee; Coleman; Davis; Durkheim; Festinger; Fiedler; Homans; Katz and Lazarsfeld; Lazarsfeld and Merton; Lipset, Trow, and Colem...
