tive cues are certainly salient in the perception that a neighborhood is “disorderly.” But so too, we argue, are cultural stereotypes about disorder in American society. In the research summarized in this article we set aside the usual questions about whether disorder is linked to crime or poor health. Instead we examine what predicts individuals’ perceptions that disorder, defined in the manne...

Morphogenesis in the embryo involves the bending, folding and fusing of epithelial tissues to create the final complex shapes of the various organs and structures in the body. One essential process that occurs frequently during development is the drawing together and fusion of epithelial edges. Drosophila dorsal closure is perhaps the most genetically tractable of this type of movement, and sev...

We present an original approach of virtual sculpting incarnated in a unified space-time interactive modeler named Splimo (for Spline Modeler), which is specifically designed for the creation of tubular spline works. Oriented towards artistic creation, it allows the realization of virtual transcriptions of real art pieces, as well as the creation of animated virtual sculptures, presented in an e...

Though a large variety of methods has been developed to model 3D objects, most of them are based on the construction of solid objects or curved surfaces. This work is part of a sketch-based project for modeling arbitrarily polygonal shapes. The method for modeling 3D objects is based on the user drawing or removing of edges. This paper addresses the automatic computation of the 3D polygonal sur...

scoreLight is a playful musical instrument capable of generating sound from the lines of drawings as well as from the edges of three-dimensional objects nearby (including everyday objects, sculptures and architectural details, but also the performer’s hands or even the moving silhouettes of dancers). There is no camera nor projector: a laser spot explores shapes as a pick-up head would search f...

This thesis is centred around the question of how dynamic pictures can be created and manipulated directly, analogous to drawing images, in an attempt to overcome traditional abstract textual program representations and interfaces (coding). To explore new ideas, Vogo1 is presented, an experimental, spatially-oriented, direct manipulation, live programming environment for Logo Turtle Graphics. I...

The manuscript offers a conceptualization and formalization of the notion of choice undecidability of an individual actor within a post-structural approach to social theory. In contrast to conventional decision theories which posit that the actors are able to delineate the set of alternative choices, this paper explores how choice undecidability shapes the decision-making process in strategic s...

The article focuses on varying protest intensities of social movement activists in an authoritarian political environment. Drawing on a sample of participants in El Salvador’s El movimiento popular, the paper examines how structural location in the resistance movement’s multi-sectoral organizational infrastructure shapes the level of participation. Those motivated by state repression and mainta...

A plane graph is a planar graph with a fixed planar embedding in the plane. In a boxrectangular drawing of a plane graph, every vertex is drawn as a rectangle, called a box, each edge is drawn as either a horizontal line segment or a vertical line segment, and the contour of each face is drawn as a rectangle. A planar graph is said to have a box-rectangular drawing if at least one of its plane ...
