Skilled immigrants have achieved great success in founding U.S. engineering and technology startups, which have in turn contributed greatly to the country's economic growth over time. In this work we explore the educational attainment and career trajectories of these immigrant entrepreneurs. Our research confirms that advanced education in STEM fields (science, technology, engineering and...

The last decades have seen tremendous growth and transformation in the Internet's commercial landscape. Underneath this success, however, the underlying network architecture has shown a marked resistance to change; it is now described as stagnant and ossified. Numerous design proposals have been developed by researchers, implemented in code, and written right into the routers and end-systems...

This dissertation is a collection of papers quite varied in the methods used and the topics examined. Common to them all is a focus on the use of information and the use of experiments and quantitative methods for the analysis. In the three experiments I look at the question of monetizing information goods available on the internet; issues of privacy where personal information is the main...

The dissertation looks at the practice of software development in Rio de Janeiro, Brazil — a place at the periphery of the global world of software development. Software development is often conceptualized as a placeless field of endeavor. At the same time software work is highly concentrated, with "right" and "wrong" places to do it. Ethnographic data from a "wrong place" helps challenge some...

Many of the most complex service systems being built and imagined today combine person-to-person encounters, technology-enhanced encounters, self-service, computational services, multi-channel, multidevice, and location-based and context-aware services. This paper examines the characteristic concerns and methods for these seven different design contexts to propose a unifying view that spans them...

In Collaboration, author Morten Hansen takes aim at what many leaders inherently know: in today's competitive environment, company-wide collaboration is an imperative for successful strategy execution, yet the sought-after synergies are rarely, if ever, realized. In fact, most cross-unit collaborative efforts end up wasting time, money, and resources. How can managers avoid the costly...

“There has never been,” Nunberg writes, “an age as wary as ours of the tricks words can play, obscuring distinctions and smoothing over the corrugations of the actual world.... Yet as advertisers and marketers know, our mistrust of words doesn't inoculate us against them.” These are the years of talking dangerously, and Nunberg is a sure guide to the pitfalls. With illuminating intelligence...

Through the work of constructing a field site, researchers define the objects and subjects of their research. This article explores a variety of strategies devised by researchers to map social research onto spatial terrain. Virtual networked field sites are among the recent approaches that are challenging conventional thinking about field-based research. The benefits and consequences of one...

This article reports empirical findings from four inter-related studies, with an emphasis on collocated sharing. Collocated sharing remains important, using both traditional and emerging image-related technologies. Co-present viewing is a dynamic, improvisational construction of a contingent, situated interaction between story-teller and audience. The concept of performance, as articulated...

We introduce Tangible Message Bubbles, a new composition and communication tool that invites youngsters to express and record their everyday expressions, play with these original recordings, and share these personal creations with their friends and family. We present a design rationale that focuses on supporting both co-located and remote collaboration, and on balancing play with tool design....

We introduce a mixed physical and digital programming environment for children to control robotic characters. We present our design rationale, our initial prototype, report the results from our initial evaluation, and discuss ongoing work.

Many Web-based data sources and services are available as feeds, a model that provides consumers with a loosely coupled way of interacting with providers. The current feed model is limited in its capabilities, however. Though it is simple to implement and scales well, it cannot be transferred to a wider range of application scenarios. This paper conceptualizes feeds as a way to serialize query...

In this paper we present a study comparing speech and dialed input voice user interfaces for farmers in Gujarat, India. We ran a controlled, between-subjects experiment with 45 participants. We found that the task completion rates were significantly higher with dialed input, particularly for subjects under age 30 and those with less than an eighth grade education. Additionally, participants using...
