The impact of cellular phones on society: Research Paper

In this paper we propose to take advantage of the rapid improvements in commercial CMOS sensors and microscopic optics driven by the cell-phone industry to develop two common biomedical devices, namely a microscope and spectrometer, that are available as simple and inexpensive add-ons to a commercial cell phone camera. While other researchers have demonstrated previously similar devices, our attachments to the phone are much smaller, simpler, and very low cost while still maintaining an acceptable level of performance. We demonstrate their relevance in laboratory measurements as well as discuss their applications within the field of science education.

The IBM work was done as part of a research challenge dubbed , in which the telecom giant Orange released 2.5 billion call records from five million cell-phone users in Ivory Coast. The records were gathered between December 2011 and April 2012. The data release is the largest of its kind ever done. The records were cleaned to prevent anyone identifying the users, but they still include useful information about these users’ movements. The IBM paper is one of scores being aired later this week at a at MIT.

Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged brain DNA. He maintains a database that holds 400 scientific papers on possible biological effects of radiation from wireless communication. He found that 28 percent of studies with cellphone industry funding showed some sort of effect, while 67 percent of studies without such funding did so. “That’s not trivial,” he said.

How Cell Phones Have Changed Us Socially - Research Paper

This paper updates and extends a previous Pew Research Center study of possible non -coverage bias in social and political surveys conducted by telephone. To do so, we compare weighted estimates from landline samples to those obtained from combined samples of landline and cell respondents. In addition to examining the potential for biased estimates, we also compare the demographic characteristics of samples obtained from landline sampling frames with those that include cell phones. We conclude by addressing the practical considerations faced in calling cell phone samples, including costs and response rates.

With health care costs increasing throughout the world, there is a pressing need for reducing the cost and complexity of biomedical devices . Additionally, with growing demand for high-quality health care in regions of the world where medical infrastructure is below levels found in developed countries, portable devices that can transmit relevant data to remote experts are likely to have a large impact on quantity and quality of care. To this end, several groups have focused on the development of low-cost and rapidly deployable technologies that address common diseases afflicting the third world and common tests performed in both hospital and field environments –. Cell phone cameras are certainly the most ubiquitous optical sensor in both the developed and developing worlds, and are attractive candidates for conversion to medical devices. Some work has already been directed towards this end, with several recent papers discussing the use of cell phones as diagnostic devices. Researchers at UCLA have constructed a modified lensless cell phone that enables holography-based digital microscopy , while researchers at UC Berkeley have constructed a complex objective attachment that also transforms a cell phone into a microscope . Additionally, a patent was recently awarded for the use of a cell phone as a spectrometer . However, there is still a need for more research directed towards utilizing cell-phone cameras to record images or spectra of biological samples.
