This chapter presents some results about groups generated by reflections and the standard metric on a Bruhat-Tits building. It begins with definitions relating to an affine subspace, an affine hyperplane, an affine span, an affine map, and an affine transformation. It then considers a notation stating that the convex closure of a subset a of X is the intersection of all convex sets containing a and another notation that denotes by AGL(X) the group of all affine transformations of X and by Trans(X) the set of all translations of X. It also describes Euclidean spaces and assumes that the real vector space X is of finite dimension n and that d is a Euclidean metric on X. Finally, it discusses Euclidean representations and the standard metric.

AbstractThis paper sheds light on Syrian refugee women’s negotiation strategies in language learning classrooms and in their broader social contexts from an intersectional perspective. Drawing on in-depth interviews and focus groups complemented by participatory observation in language classes, we use a post-structuralist approach to examine gendered language socialization. Our research combines an intersectional framework and a Bourdieusian perspective on symbolic capital to show how women perform gender and negotiate their roles in classrooms, within families and vis-à-vis the host society. The findings demonstrate that being a woman and a migrant presents particular challenges in learning language. At the same time, learning language allows for the re-negotiation of gender relations and power dynamics. We find that gender structures women’s access to linguistic resources and interactional opportunities as they perform language under social pressure to conform to prescribed roles as mothers, wives and virtuous, and shy women. Yet, these roles are not static: gender roles are also reconstituted in the process of language learning and gaining symbolic capital.

An adult, who is blind, with modest experience in drawing, drew a cube in parallel and sideways inverse perspective, with Y and T junctions common in drawings by sighted 9- to 11-year-old children. Drawing development may be similar in the blind and sighted.

A new deep drawing process of sheet metals is developed to facilitate small-lot production of deep cups with large drawing ratio. In this process, unlike the conventional deep drawing method, a few drawn cups are always stacked on the punch and used as a part of punch for the subsequent deep drawing of a given blank. Before drawing a new blank, a drawn cup which is in contact with the punch is stripped off. The repetition of such stripping and drawing operations makes it possible to carry out both the first-stage drawing and the subsequent slight redrawings in one drawing operation using only one pair of punch and die. In this paper, this new deep drawing process is applied to the production of tapered cups and the main feature of the process is shown.
