The autonomous life: a pure social view

In this paper I propose and develop a social account of global autonomy. On this view, a person is autonomous simply to the extent to which it is difficult for others to subject her to their wills. I argue that many properties commonly thought necessary for autonomy are in fact properties that tend to increase an agent’s immunity to such interpersonal subjection, and that the proposed account is therefore capable of providing theoretical unity to many of the otherwise heterogeneous requirements of autonomy familiar from recent discussions. Specifically, I discuss three such requirements: (i) possession of legally protected status, (ii) a sense of one’s own self- worth, and (iii) a capacity for critical reflection. I argue that the proposed account is not only theoretically satisfying but also yields a rich and attractive conception of autonomy

Electrophoretic Analysis of Blood Serum Proteins in Three Species of Water Snakes (Genus Nerodia)

Serum from three species of water snakes (Nerodia rhombifera, N. erythrogaster and N. fasciata) from one geographic region was analyzed electrophoretically on cellulose acetate, and anodic mobility and relative concentration of the fractions were determined by a recording densitometer with an automatic integrator. Classification of fractions was based on mobility (Rf, values), and for identification purposes, bands were labeled in order of decreasing mobility (albumin and alpha₁, alpha₂, alpha₃, beta₁, beta₂, gamma₁, and gamma₂ globulins). Seven fractions were identified in each species with alpha₃ being absent from N. rhombifera and N. erythrogaster, and only one gamma fraction was observed in N. fasciata. In the three species, gamma globulin was the predominant protein (42-46%), and albumin levels were characteristically low ;however, a distinct difference was observed in albumin concentration (N. fasciata, 7%; N. rhombifera and N. erythrogaster, 16-18%). The Rf values and relative concentrations of other globulins showed heterogeneity in the three species, with the protein pattern of N. fasciata being distinct from the other two species

Testing the use of bomb radiocarbon to date the surface layers of blanket peat

The recently formed surface layers of peatlands are archives of past environmental conditions and can have a temporal resolution considerably greater than deeper layers. The low density and conditions of fluctuating water table have hindered attempts to construct chronologies for these peats. We tested the use of the radiocarbon bomb pulse to date recently accumulated peat in a blanket mire. The site was chosen because the peat profiles contained independent chronological markers in the form of charcoal-rich layers produced from known burning events. We compared chronologies derived from accelerator mass spectrometry C-14 analysis of plant macrofossils against these chronological markers. The bomb C-14-derived chronologies were in broad agreement with the charcoal dating evidence. However, there were uncertainties in the final interpretation of the C- 14 results because the pattern of C-14 concentration in the peat profiles did not follow closely the known atmospheric C-14 record. Furthermore, samples of different macrofossil materials from the same depth contained considerable differences in C-14. Suggested explanations for the observed results include the following: i) minor disturbance at the site, ii) in-situ contamination of the C-14 samples by carbonaceous soot, and iii) differential incorporation of plant material during blanket peat growth
