Guidelines For Pursuing and Revealing Data Abstractions
Many data abstraction types, such as networks or set relationships, remain
unfamiliar to data workers beyond the visualization research community. We
conduct a survey and series of interviews about how people describe their data,
either directly or indirectly. We refer to the latter as latent data
abstractions. We conduct a Grounded Theory analysis that (1) interprets the
extent to which latent data abstractions exist, (2) reveals the far-reaching
effects that the interventionist pursuit of such abstractions can have on data
workers, (3) describes why and when data workers may resist such explorations,
and (4) suggests how to take advantage of opportunities and mitigate risks
through transparency about visualization research perspectives and agendas. We
then use the themes and codes discovered in the Grounded Theory analysis to
develop guidelines for data abstraction in visualization projects. To continue
the discussion, we make our dataset open along with a visual interface for
further exploration
Data-Intensive Computing in the 21st Century
The deluge of data that future applications must process—in domains ranging from science to business informatics—creates a compelling argument for substantially increased R&D targeted at discovering scalable hardware and software solutions for data-intensive problems
IVOA Recommendation: Simple Cone Search Version 1.03
This specification defines a simple query protocol for retrieving records
from a catalog of astronomical sources. The query describes sky position and an
angular distance, defining a cone on the sky. The response returns a list of
astronomical sources from the catalog whose positions lie within the cone,
formatted as a VOTable. This version of the specification is essentially a
transcription of the original Cone Search specification in order to move it
into the IVOA standardization process
Pick-n-mix approaches to technology supply : XML as a standard “glue” linking universalised locals
We report on our experiences in a participatory design project to develop ICTs in a hospital ward
working with deliberate self-harm patients. This project involves the creation and constant re-creation of
sociotechnical ensembles in which XML-related technologies may come to play vital roles. The importance of
these technologies arises from the aim underlying the project of creating systems that are shaped in locally
meaningful ways but reach beyond their immediate context to gain wider importance. We argue that XML is
well placed to play the role of "glue" that binds multiple such systems together. We analyse the implications of
localised systems development for technology supply and argue that inscriptions that are evident in XML-related
standards are and will be very important for the uptake of XML technologies
A Voice is Worth a Thousand Words: The Implications of the Micro-Coding of Social Signals in Speech for Trust Research
While self-report measures are often highly reliable for field research on trust (Mayer and Davis, 1999), subjects often cannot complete surveys during real time interactions. In contrast, the social signals that are embedded in the non-linguistic elements of conversations can be captured in real time and extracted with the assistance of computer coding. This chapter seeks to understand how computer-coded social signals are related to interpersonal trust
