Sex Workers In Pakistan Give Recommendations On HIV Prevention To Health Officials
Although the recorded HIV prevalence in Pakistan is relatively low, health officials are concerned that a concentrated epidemic of the virus among injection drug users could carry over to commercial sex workers and other high risk groups in the country, IRIN/PlusNews reports. To address the issue, the National AIDS Control Program and the United Nations Population Fund recently held a meeting, called the National Consultation on HIV and Sex Work, in an effort to improve HIV prevention efforts targeted at sex workers by consulting with workers in the field.Sex workers at the meeting made various recommendations, including HIV testing, referrals and increased efforts to decrease stigma. The Ministry of Health reports that from 2006 to 2007, female sex workers were at a high risk of HIV in 12 cities across Pakistan. A survey of 4,639 female sex workers found that less than 25% reported condom use; 10% had a partner that had used injection drugs during the past six months; and that illiterate sex workers were less likely to use condoms than those with a higher level of education. A female sex worker at the meeting said, "It is very hard for us to convince [partners] to put on a condom, but I feel that a female condom would put us in a position where we can protect ourselves against HIV and sexually transmitted infections." She added that female condoms are not widely available. Legalizing sex work would make it easier for sex workers to protect their rights, another female sex worker at the conference said. She added that often, outreach workers face barriers from police forces. Daniel Baker, UNFPA"s country representative for Pakistan, said that sex workers should have greater involvement in creating and implementing HIV programs. He added, "The female sex workers have to be in there as managers, workers and leaders to benefit in the long run." Safdar Kamal Pasha with UNFPA agreed that the recommendations from sex workers are critical points to address in future programming. "The female sex workers agreed that there should be vocational training and the means for alternative work opportunities for those who want to move out of sex work, as well as those who are past their prime and do not find sustainability in sex work," Pasha said (IRIN/PlusNews, 5/14).

Cell Phone Towers Can Help Predict The Next Big Flood

TAU research finds cell phone towers can help predict the next big flood Though New Orleans residents were told to evacuate days before the arrival of Hurricane Katrina, no one could have predicted the real extent of the devastation. Now researchers from Tel Aviv University say they have found a novel and reliable way to help predict the intensity of the next big flood, using common cell phone towers across the United States. Their model, which analyzes cell phone signals, adds a critical component to weather forecasting never before available. "By monitoring the specific and fluctuating atmospheric moisture around cell phone towers throughout America, we can cheaply, effectively and reliably provide a more accurate "critical moisture distribution" level for fine-tuning model predictions of big floods," says Prof. Pinhas Alpert, a geophysicist and head of Tel Aviv University"s Porter School for Environmental Education. Prof. Alpert and his co-researchers Prof. Hagit Messer Yaron and doctoral fellow Noam David reported on their research in the April 2009 Atmospheric Chemistry and Physics. Information the weather girl can use Cell phone towers emit radio waves that are diminished by moisture in the air, a factor that can be used to improve model warnings on flood levels. In addition, the researchers measured the rainfall distributions and were able to accurately estimate the size of impending floods before they struck. This was demonstrated in post-analysis of two case-studies of floods in the Judean Desert in Israel, where cell phone towers - and flash floods - are abundant. Using real data measurements collected from the towers, the researchers demonstrated how microwave links in a cellular network correlated with surface station humidity measurements. The data provided by cell phone towers is the missing link weather forecasters need to improve the accuracy of flood forecasting. The microwave data used in this study was supplied by two cellular providers Cellcom and Pelephone in Israel. Can texting save lives? "Our method provides reliable measurement of moisture fields near the flood zone for the first time," notes Prof. Alpert, who also works with NASA on developing models to study global warming weather patterns. This new tool, he says, can add to the bigger picture of understanding climate change patterns in general. "Accurate predictions of flooding were difficult before because there haven"t been enough reliable measurements of moisture fields in remote locations," Prof. Alpert adds. Using the signals collected from cell phone towers as they communicate with base stations and our handsets, weather forecasters will now have a crucial missing piece of information for flood prediction that they never had before. It will permit forecasters and residents alike to more accurately gauge the danger they face from an impending flood. Because hundreds of thousands of cell phone towers are already in place, the Tel Aviv University invention can be adopted quickly. And cell phone companies are already collecting the data anyway, as Americans continue to ramp up their minutes of call time every month. George Hunka American Friends of Tel Aviv University
