The concentration of 7,12-dimethylbenz(a)anthracene ( D M B A ) i n mamm-Lry tissue was determined at different time intervals following its administration, in a single dose, to female Sprague-Dawley rats maintained on 3 different semisynthetic diets: low fat, high coconut oil, and high corn oil. In general, the rate of uptake and clearance of the carcinogen was similar in the 3 groups, with a ...

Kibbutzim differ from one another in democratic and egalitarian practice and in equality itself. We explore hypotheses in 49 kibbutzim that attempt to explain these differences by the opposing effects of a technological imperative that implies a rational striving for economic efiiciency and an ideological imperative that implies a commitment by members to traditional kibbutz values. Cross secti...

Locally parallel dense patterns sometimes called texture flows define a perceptually coherent structure which is important to image segmentation, edge classification, shading analysis, and shape interpretation. This paper develops the notion of texture flow from a geometrical point of view to argue that local measurements of such structures must incorporate two curvatures. We show how basic the...

One common criticism of “nudges” — general-purpose interventions derived from behavioral science that can be applied to a range of policy objectives — is that such interventions are manipulative and coercive. In this article we show that this criticism sometimes reflects a partisan nudge bias, whereby attitudes toward policy goals or policymakers distort feelings about policy interventions. In ...

Using the two fundamental dimensions of social judgment, warmth and competence, we show that, contrary to general models of impression formation, negative information on one dimension has positive consequences on the way a target is judged on the other dimension. Participants learned about two groups which were either congruent on warmth and competence (one group high on both and the other low ...

growths of the Walker 256 rat tumor suitable for quantitative experimentation have been described in a previous paper (14). The contributions of the adrenal and pituitary glands to the control of growth rate of intramuscular Walker tumor im plants are the subject of this paper. The study of the effects of endocrine extirpa tions is complicated by the large changes in ap petite with resultant di...
