It is generally accepted that butterfly wing color-patterns have ecological and behavioral functions that evolved through natural selection. However, particular wing color-patterns may be produced physiologically in response to environmental stress, and they may lack significant function. These patterns would represent an extreme expression of phenotypic plasticity and can eventually be fixed g...

change in two stands of jack pine (Pinus banksiana Lamb.) and one stand of black spruce (Picea mariana (Mill.) B.S.P.) on relatively clear days from late May until mid-September 1994. Field measurements were made with a portable infrared gas analyzer, and laboratory measurements included photosynthetic oxygen evolution and needle chemical composition. Seasonally averaged light-saturated assimil...

In a two-frame apparent motion display, a test grating was displaced horizontally or vertically in the presence of an inducer of which component gratings made up expanding/contracting or rotational motion as a whole. In the first experiment, we demonstrated that motion assimilation did occur for the test accompanied by the two-dimensional motion of the inducer. In the second experiment, we show...

Ethnic Segregation in Germany This paper provides a comprehensive description of the nature and extent of ethnic segregation in Germany. Using matched employer-employee data for the universe of German workers over the period 1975 to 2008, I show that there is substantial ethnic segregation across both workplaces and residential locations and that the extent of segregation has been relatively st...

Cocconeis diminuta, a marine benthic diatom, metabolizes acetate and lactate-(14)C. In the light, the major product was lipid, whereas in the dark, CO(2) was the major product. Analysis of proteins synthesized in the presence of acetate or lactate showed that radioactivity was incorporated predominantly into the glutamate family of amino acids and those amino acids related directly to the subst...

The Kuramoto-Sivashinsky equation plays an important role as a low-dimensional prototype for complicated fluid dynamics systems having been studied due to its chaotic pattern forming behavior. Up to now, efforts to carry out data assimilation with this 1-d model were quasi totally restricted to variational adjoint methods domain and only Chorin and Krause [26] tested it using a sequential Bayes...

This study examined 3 strategies that African American and White participants (9th–12th grade) used to manage cultural diversity: multicultural, separation, and assimilation/acculturation strategies. Older African American adolescents endorsed multicultural strategies (integration/fusion and alternation) more strongly and separation less strongly than their younger African American peers. The r...

ABSTRACT. Net photosynthesis, dark respiration, chlorophyll and carbohydrate content, and leaf and shoot growth in plants of evergreen olive (Olea europaea L.) grown under controlled conditions were measured to assess changes in carbon balance during leaf development of the 6th, 12th, and 16th node (from the base, first flush) through expansion to maturity. Shoot and leaves expanded in a sigmoi...

Models of speech perception have shown divergent views concerning the mechanisms that underlie perception of assimilated speech. In the present study, we evaluated an existing probabilistic model for English place assimilation and conducted a series of simulations on voice assimilated speech in French. The model was trained on a realistic acoustic-phonetic data set of word-final assimilated sto...

Previous research on self-other similarity judgments has demonstrated that perceived similarity between self and other depends on the focus of comparison. Based on the Selective Accessibility model, which assumes that comparisons with similar others yield assimilation, whereas comparisons with dissimilar others yield contrast, the author hypothesized that the focus of a social comparison would ...
