This thesis presents two studies into factors that influence speed of passing documents on a tabletop display. Document passing consist of rotation and translation tasks. Two interaction techniques that support both rotation and translation, RNT and Corner, were compared in both studies. The RNT technique is an semi-integral technique and combines rotation and translation. The Corner technique ...

Interpersonal interactions are important for understanding individual labor-market outcomes. This paper develops a framework to understand the role of interpersonal interactions in the labor market including task assignment and wages. Interactions between people are modeled as a trade-off between caring and directness, both of which can be either beneficial or detrimental. Caring is needed to e...

direct manipulation, direct conversation, user interface, metaphor, modality The earliest interactive computer systems were based on a conversational mode of interaction, in which user and computer communicated through the exchange of linguistic utterances. Since the advent of 'direct manipulation' technology, there has been a tendency to develop and promote an alternative mode of interaction, ...

Gender affects performance on a variety of cognitive tasks, and this impact may stem from socio-cultural factors such as gender stereotyping. Here we systematically manipulated gender stereotype messages on a social cognition task on which no initial gender gap has been documented. The outcome reveals: (i) Stereotyping affects both females and males, with a more pronounced impact on females. Ye...

This paper presents a mathematical methodology for transit route network optimization. The goal is to provide an effective computational tool for the optimization of large-scale transit route networks. The objectives are to minimize transfers and optimize route directness while maximizing service coverage. The formulation of the methodology consists of three parts: (1) representation of transit...

BackgroundUrban design features are often studied in relation to health and behavioural outcomes. They can also have major implications for environmental However, the impact of these on both outcomes (co-benefits) is rarely examined. We investigated how urban landscape street profiles related jointly occurring Latin America cities.MethodsWe used data from Salud Urbana en América Latina (SALURBA...

INTRODUCTION An essential component of technical editors’ work is to convey to writers how their documents would benefit from revision. This task is potentially sensitive, given writers’ intellectual and emotional investment in the documents they have created. The sensitive nature of the editing process is clear in Rude’s (2001) advice to students of technical editing: “[A]void words that sugge...

We study the algebraic structure of directed bigraphs, a bigraphical model of computations with locations, connections and resources previously introduced as a unifying generalization of other variants of bigraphs. We give a sound and complete axiomatization of the (pre)category of directed bigraphs. Using this axiomatization, we give an adequate encoding of the Fusion calculus, showing the uti...
