Most existing work on the demand for health insurance focuses on employees' decisions to enroll in employer-provided plans. Yet any attempt to achieve universal coverage must focus on the uninsured, the vast majority of whom are not offered employer-sponsored insurance. In the summer of 2008, we conducted a survey experiment to assess the willingness to pay for a health plan among a large sampl...

This study investigated the opportunity to learn (OTL) that is available to Grade 12 mathematics learners. Learner workbooks were analysed in terms of time on task, curriculum coverage, curriculum coherence, and cognitive demand. Based on these elements, experienced mathematics teachers judged the opportunity that the learners have to achieve more than 60% for each topic. According to the workb...

Self-medication is a common practice in many developing countries but little is known about its determinants. This study analyzes the factors that are associated with the use of self-medication in Mexico using the Mexican Health and Aging Study, a new nationally representative survey on adults aged 50 and over. We find that self-medication is related to socioeconomic status and the lack of acce...

The growing demand in mobile Internet access calls for high capacity and energy efficient cellular access with better cell coverage. The in-band relaying solution, proposed in LTE-Advanced, improves coverage without requiring additional spectrum for backhauling, making its deployment more economical and practical. However, in-band relay without careful management incurs low spectrum utilization...

For 3G cellular networks, capacity becomes an additional objective along with coverage when characterizing the performance of high-data-rate services. Since network capacity depends on the degree traffic load is balanced over all cells, changing traffic patterns demand dynamic network reconfiguration to maintain good performance. We study the competitive character network coverage and capacity ...

The demand for Wireless Sensor Networks (WSN) has motivated the researchers to obtain energy optimized solutions, because of the constraint on the limited use of energy in these networks. In WSN, apart from energy optimization there are many other areas such as, coverage of the target area and the connectivity of the network for data routing, which attract the attention of researchers for optim...

This paper traces the relationship between insurance coverage and the technology-induced shift of the locus of medical care and medical spending from the inpatient to the outpatient setting. This shift was accompanied by an increase in the extent of private insurance coverage for outpatient treatments; technological change both caused the increase in coverage (for more costly treatments) and wa...

With the growing demand of very high bandwidth services such as high definition IP Television (IPTV), Service Providers (SPs) are moving to fiber-based solutions such as Passive Optical Networks (PONs) to meet current and future bandwidth needs. As these networks are deployed, coverage tends to directly affect Capital Expenditure (CAPEX) per subscriber served, with a minimum cost per Optical Ne...
