The increasing inclusion of location and other contextual information in social media applications requires users to be more aware of what their location disclosures reveal. As such, it is important to consider whether existing access-control mechanisms for managing location sharing meet the needs of today’s users. We report on a questionnaire (N = 103) in which respondents were asked to specif...
Evidence-based behavior change interventions addressing health systems must be identified and disseminated to improve child health outcomes. Studies of the efficacy of such interventions were identified from systematic searches of the published literature. Two hundred twenty-nine of the initially identified references were judged to be relevant and were further reviewed for the quality and stre...
We present a framework for studying the problem of media streaming in technology and cost heterogeneous environments. We first address the problem of efficient streaming in a technologyheterogeneous setting. We employ random linear network coding to simplify the packet selection strategies and alleviate issues such as duplicate packet reception. Then, we study the problem of media streaming fro...
Traditional modes of communication, including songs, riddles, appelations, and proverbs, remain predominant in small African communities and should be given greater attention as a means of disseminating government policy on family planning. An examination of the folklore of the Akan, an ethnic group in Ghana, demonstrates both the power of traditional communication and its intrinsic stability ...

Content analysis of social media policies for all institutions listed in the Carnegie Classification Data File revealed that less than one-quarter of institutions had an accessible social media policy.

Variability in generational behavior of cache blocks is a key challenge for cache management policies that aim to identify dead blocks as early and as accurately as possible to maximize cache efficiency. Existing management policies are limited by the metrics they use to identify dead blocks, leading to low coverage and/or low accuracy in the face of variability. In response, we introduce a new...
On online social media, users join new online social networks (OSNs) to exploit variety of services while maintaining their old identities on other OSNs. A user maintains an identity on each OSN mentioning metadata (e.g. profile information) about her. Heterogeneity of metadata shared by user across OSNs leads to a problem of finding if two online identities on multiple OSNs belong to the same ...
This article is part of a series written for people responsible for making decisions about health policies and programmes and for those who support these decision makers. In this article, we address strategies to inform and engage the public in policy development and implementation. The importance of engaging the public (both patients and citizens) at all levels of health systems is widely reco...
This paper provides a methodology to assess the efficiency of mean residual life (MRL) in condition-based maintenance decision-making for a system subjected to the competing and dependent risks of degradation and shock. Based on this system, the cost models of two quite simple policies implementing MRL-based or degradation-based preventive replacement are developed and compared with each other....
Intravenous contrast agents are frequent adjuncts used in diagnostic imaging. Despite the well-recognized complications of contrast media extravasation, its treatment remains an enigma to many. This article reviews the recognition, prevention and treatment options, with a summary of the contrast media extravasation policy implemented in our department.
