Bend it like pollen
images inspired by the remarkable twists and turns in the shape of pollen grains from different plant species collected by the artist from specimens growing in the gardens' cornfield last summer. Kessler was awarded a three-year grant to work with Madeline Harley at the Micromorphology Unit at Kew. The remarkable shapes of pollen grains reveal important diagnostic features of plants used by sci...
متن کاملIf you stretch it, they will come
n page 703, Kelso et al. complete the trilogy of actin papers with a detailed biochemical analysis of the Drosophila Kelch protein. Like the Arp2/3 complex, Kelch is required for proper actin organization in ovarian ring canals. Although the structure of Kelch suggested that it might act as a dimeric actin cross-linking protein, this activity had not yet been demonstrated. In an impressive seri...
متن کاملBend It Like Beckham: Ethnic Identity and Integration∗
We propose a theoretical framework to study the determinants of ethnic and religious identity along two distinct motivational processes: cultural distinction and cultural conformity. Under cultural conformity, ethnic identity is reduced by neighborhood integration, which weakens group loyalties and prejudices. On the contrary, under cultural distinction, ethnic minorities are more motivated in ...
متن کامل‘Bend It Like Beckham’: Identity, Socialization, and Assimilation∗
This paper is about ethnic identity. We first develop a model of an individual’s identity as resulting from the interaction of the individual’s identity choice, cultural transmission and socialization inside the family, peer effects and social interactions. We then put the model to data using the UK Fourth National Survey of Ethnic Minorities. We show that the main determinants of the intensity...
متن کاملAverage Stretch Factor: How Low Does It Go?
In a geometric graph, G, the stretch factor between two vertices, u and w, is the ratio between the Euclidean length of the shortest path from u to w in G and the Euclidean distance between u and w. The average stretch factor of G is the average stretch factor taken over all pairs of vertices in G. We show that for any set, V , of n points in Rd , there exists a geometric graph with vertex set ...
