We explore how telephone-based services might be mass adopted by low-literate users in the developing world. We focus on speech and push-button dialog systems requiring neither literacy nor training. Building on the success of Polly, a simple telephone-based voice manipulation and forwarding system that was first tested in 2011, we report on its first large-scale sustained deployment. In 24/7 operation in Pakistan since May 9, 2012, as of mid-September Polly has spread to 85,000 users, engaging them in 495,000 interactions, and is continuing to spread to 1,000 new people daily. It has also attracted 27,000 people to a job search service, who in turn listened 279,000 times to job ads and forwarded them 22,000 times to their friends. We report users' activity over time and across demographics, analyze user behavior within several randomized controlled trials, and describe lessons learned regarding spread, scalability and sustainability of telephone-based speechbased services.
Background: The present study was undertaken for assessing C reactive proteins levels in dental implant failure patients. Materials & methods: A total of 100 patients who were schedule to undergo prosthetic rehabilitation of missing mandibular molars were enrolled. Baseline hematological and biochemical variables were evaluated. All the dental implant procedures were carried out under adequate septic conditions. All the patients were put of prescribed antibiotic therapy postoperatively. All the patients were evaluated radiographically after three months for prognosis. C Reactive proteins levels were evaluated in all the patients and were compared between patients on the basis of prognosis. All the results were recorded in Microsoft excel sheet and were subjected to statistical analysis using SPSS software. Results: Mean C Reactive proteins levels among patients with Dental implant failure and among patients with successful dental implants was 0.89 mg/dL and 0.21 mg/dL respectively. Significant results were obtained while comparing the C Reactive proteins levels among patients with Dental implant failure and among patients with successful dental implants.Conclusion: C Reactive proteins could be used as a successful marker for monitoring the success dental implant therapy.
1We have been developing techniques for spreading telephonebased services to low-literate people in the developing world, bypassing the need for explicit user training. We achieve this by using entertainment as a viral conduit to spread and popularize development related voice-based services. Polly, our telephonebased voice manipulation and forwarding system, has been in continuous operation in Pakistan since May 2012. In this poster, we show the geographical spread of Polly over the initial four months of its deployment. We then describe our attempts at reducing our operating costs by shifting some of them to users, and the impact this had on user behavior, demonstrated via randomized control trials and by the usage of landline vs. mobile phones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
