Comparing the contributions of context and prosody in text-independent dialog act recognition
We propose a framework for employing both speech/non-speech-based (“contextual”) features and prosodic features, and apply it to DA segmentation and classification in multiparty meetings.

Dynamics of North American Sector Ionospheric and Thermospheric Response During the November 2004 Superstorm
We present a study of ionospheric and thermospheric response during a November 9–10, 2004 major geomagnetic storm event (DsT ∼−300 nT).

A Partially Linear Tree-Based Regression Model for Multivariate Outcomes
We propose a multilocus association test for the study of multivariate traits. The test is derived from a partially linear tree-based regression model for multiple outcomes.

Increase in Tissue Inhibitor of Metalloproteinase-2 (TIMP-2) Levels and Inhibition of MMP-2 Activity in a Metastatic Breast Cancer Cell Line by an Anti-Invasive Small Molecule SR13179
We report that a novel small molecule synthetic flavanoid SR13179, which inhibits the invasion of a highly metastatic human breast cancer cell line MCF-10CA1a through Matrigel, significantly increases protein and…

Nicotinic Receptor-Mediated Reduction in L-DOPA-Induced Dyskinesias May Occur Via Desensitization
The present experiments were performed to understand the mechanisms whereby nicotine reduces l-DOPA-induced AIMs. We used a well established model of dyskinesias, l-DOPA-treated unilateral 6-hydroxydopamine-lesioned rats.

From documents to tasks: deriving user tasks from document usage patterns
In order to reduce the necessary amount of training, this paper proposes a new approach for automatically estimating a user's tasks from document interactions in an unsupervised manner.

Information seeking with social signals: anatomy of a social tag-based exploratory search browser
In this paper, we present the algorithm of a tag-based exploratory system based on this idea.

Temporal task footprinting: identifying routine tasks by their temporal patterns
This paper introduces a new representation for describing routine tasks, called temporal task footprints.

The capacity of wireless ad hoc networks with multi-packet reception
We compute the throughput capacity of random dense wireless ad hoc networks for multi-pair unicast trafc in which nodes are endowed with multi-packet reception (MPR) capabilities.

Collective intelligence in organizations: toward a research agenda
The workshop discusses CI tools for collaboration in work-related settings, especially for task forces now increasingly common in industry or government.

Managing inquiry-based science: Challenges in enacting complex science instruction in K-8 classrooms
In this article, we describe five interconnected management areas that need to be addressed when managing an inquiry-oriented K-8 science classroom. We introduce a pyramid model as a framework for…
