Convention: a philosophical study

In a very significant development for eHealth, broad adoption of Web 2.0 technologies and approaches coincides with the more recent emergence of Personal Health Application Platforms and Personally Controlled Health Records such as Google Health, Microsoft HealthVault, and Dossia. "Medicine 2.0" applications, services and tools are defined as Web-based services for health care consumers, caregivers, patients, health professionals, and biomedical researchers, that use Web 2.0 technologies and/or semantic web and virtual reality approaches to enable and facilitate specifically 1) social networking, 2) participation, 3) apomediation, 4) openness and 5) collaboration, within and between these user groups. The Journal of Medical Internet Research (JMIR) publishes a Medicine 2.0 theme issue and sponsors a conference on "How Social Networking and Web 2.0 changes Health, Health Care, Medicine and Biomedical Research", to stimulate and encourage research in these five areas.

Medicine 2.0: Social Networking, Collaboration, Participation, Apomediation, and Openness

Television is the source of the most broadly shared images and messages
in history. It is the mainstream of the common symbolic environment into
which our children are born and in which we all live out our lives. Even
though new forms of media seem to sprout up weekly, television’s mass
ritual shows no signs of weakening, as its consequences are increasingly
felt around the globe.

Growing Up with Television: Cultivation Processes

Using an existential¨phenomenological approach, this paper describes how women with breast cancer experience the giving and receiving of social support in a computer-mediated context. Women viewed their experiences with the computer mediated support group as an additional and unique source of support in facing their illness. Anonymity within the support group fostered equalized participation and allowed women to communicate in ways that would have been more difficult in a face-to-face context. The asynchronous communication was a frustration to some participants, but some indicated that the format allowed for more thoughtful inter action. Motivations for seeking social support appeared to be a dynamic process, with a consistent progression from a position of receiving support to that of giving support. The primary benefits women received from participation in the group were communicating with other people who shared similar problems and helping others, which allowed them to change their focus from a preoc...

Experiences of women with breast cancer: exchanging social support over the CHESS computer network.

Written expression about emotionally traumatic events is associated with physical and mental health benefits, and this study examines how insightful disclosure within a computer-mediated support group for women with breast cancer affects breast cancer-related concerns, emotional well-being, and self-reported physical well-being. Using a word counting program that notes the percentage of words related to various linguistic dimensions, this research specifically examined the effects of insightful disclosure written within these groups. Surveys were administered just before group access and then 2 months and 5 months later. Insightful disclosure improved emotional well-being and reduced negative mood but did not influence breast cancer-related concerns or self-reported physical well-being. Despite the common and frequent use of computer-mediated social support (CMSS) groups for people coping with health concerns, very little research to date has quantitatively tested the effects of participating in CMSS grou...

Effects of insightful disclosure within computer mediated support groups on women with breast cancer.

We present a model of pragmatic referring expression interpretation in a grounded communication task (identifying colors from descriptions) that draws upon predictions from two recurrent neural network classifiers, a speaker and a listener, unified by a recursive pragmatic reasoning framework. Experiments show that this combined pragmatic model interprets color descriptions more accurately than the classifiers from which it is built, and that much of this improvement results from combining the speaker and listener perspectives. We observe that pragmatic reasoning helps primarily in the hardest cases: when the model must distinguish very similar colors, or when few utterances adequately express the target color. Our findings make use of a newly-collected corpus of human utterances in color reference games, which exhibit a variety of pragmatic behaviors. We also show that the embedded speaker model reproduces many of these pragmatic behaviors.

Colors in Context: A Pragmatic Neural Model for Grounded Language Understanding

Computational analysis of communication efficiency of brain networks often relies on graph-theoretic measures based on the shortest paths between network nodes. Here, we explore a communication scheme that relaxes the assumption that information travels exclusively through optimally short paths. The scheme assumes that communication between a pair of brain regions may take place through a path ensemble comprising the k-shortest paths between those regions. To explore this approach, we map path ensembles in a set of anatomical brain networks derived from diffusion imaging and tractography. We show that while considering optimally short paths excludes a significant fraction of network connections from participating in communication, considering k-shortest path ensembles allows all connections in the network to contribute. Path ensembles enable us to assess the resilience of communication pathways between brain regions, by measuring the number of alternative, disjoint paths within the ensemble, and to compare generalized measures of path length and betweenness centrality to those that result when considering only the single shortest path between node pairs. Furthermore, we find a significant correlation, indicative of a trade-off, between communication efficiency and resilience of communication pathways in structural brain networks. Finally, we use k-shortest path ensembles to demonstrate hemispherical lateralization of efficiency and resilience.
