The human body constructs itself into a person by becoming attuned to the affective consequences of its actions in social relationships. Norms develop that ground perception and action, providing standards for apprais...

A major challenge in the implementation of quantum computers is mitigating the impact of undesired couplings with the environment that lead to decoherence. Here, we discuss an error-avoiding strategy that is based upo...

This panel will address both online disasters created by anarchists and pirates and disaster relief efforts aided by information and communication technologies (ICTs). An increasing number of people use (ICTs) to mobilize their resources and enhance their activities. This mobilization has unpredictable consequences for society: On one hand, use of ICT has allowed for the mobilization of millions of people for disaster relief efforts and peace movements. On the other hand, it has also helped hackers, pirates to carryout destructive activities. In many cases it is hard to judge the moral consequences of the use of ICT by marginalized groups. The panel will present five studies of which three will focus on online disobedience and two will focus on ICT use for disaster. Together these presentations illustrate both positive and negative consequences of the new digital trends. Goodrum deliberates on an ethic of hacktivism in the context of online activism. Eschenfelder discusses user modification of or resistance to technological protection measures. Shachaf and Hara present a study of anarchists who attack information posted on Wikipedia and modify the content by deleting, renaming, reinterpreting, and recreating information according to their ideologies. Scott examines consumer media behaviors after hurricane Katrina and Rita disasters. Shankar and Ozakca discuss volunteer efforts in the aftermath of hurricane Katrina.

We present the lexico-semantic foundations underlying a multilingual lexicon the entries of which are constituted by so-called subwords. These subwords reflect semantic atomicity constraints in the medical domain which diverge from canonical lexicological understanding in NLP. We focus here on criteria to identify and delimit reasonable subword units, to group them into functionally adequate synonymy classes and to relate them by two types of lexical relations. The lexicon we implemented on the basis of these considerations forms the lexical backbone for MORPHOSAURUS, a cross-language document retrieval engine for the medical domain.

Research has been done in order to propose solutions that enhance interactions among participants and improve activity coordination in the meeting cycle. Some of these are related to pre-meeting phase conduction. We argue that collaboration could be enhanced if we supplied relevant context information through awareness mechanisms. This paper aims at evaluating context elements in an asynchronous web-based pre-meeting application. As a result, a context framework is discussed in order to support awareness design in the meeting support applications domain.

One of the most important work group support issues is providing information about the context under which a group interacts. The goal of this paper is evaluating the influence of contextual information on the cooperation level in group interactions supported by groupware. A laboratory case study was set up and carried out with this purpose.
Background: Geographic Information Systems (GIS) are powerful communication tools for public health. However, using GIS requires considerable skill and, for this reason, is sometimes limited to experts. Web-based GIS ...

Emergency Managers face a number of critical problems related to the compilation, validation, and use of Emergency Procedures. Traditional approaches do not provide enough expressiveness to accurately specify emergency procedures covering each possible scenario. As a result of this situation, Emergency Procedures are not as useful as they should be, neither in prevention nor during resolution of an emergency. In this work, we present an approach that merges two techniques to provide the broad expressiveness required when specifying Emergency Procedures. To represent sequences on actions performed by different participants we use workflow techniques. On the other hand, we use rules to represent available or mandatory actions according to the state of the system during the emergency. These rules are expressed in dynamic logic as the underlying formalism. Our approach provides more expressiveness and precision for the specification of Emergency Procedures, offering better conditions for their verification and validation. As a case study we have used part of a city subway Emergency Procedure.

We report the results of mining student learning data from SlideTutor - a cognitive tutor in a medical diagnostic domain. The analysis was aimed at finding both individual learning patterns as well as common misconceptions that students possessed. We have discovered that indeed there are distinct learner stereotypes: hint-driven learners, failure-driven learners, and a mixed group of learners that cannot be attributed to either one of the above two types. We have also found that students often make similar mistakes confusing certain visual features and diagnostic hypotheses. Our goal is to reuse the discovered patterns to engineer cross-case pedagogic interventions, enhancing our current immediate feedback methods with higher-level pedagogic reasoning. This paper describes the data-mining activities and potential implications of the data for pedagogic design.
