ASU humanities lecture offers tips on digital storytelling


October 9, 2014

While there is no substitute for good old-fashioned storytelling, a national expert says an interdisciplinary technological approach can bring to life a research paper, report or presentation.

Jonathan Davis will continue the fall 2014 Humanities Lecture Series with his presentation of “Telling Stories Through Creative Technology.” Hosted by Arizona State University’s College of Letters and Sciences and Project Humanities, the lecture starts at 6:30 p.m., Oct. 16, at the Walter Cronkite School of Journalism and Mass Communication, 555 N. Central Ave., Phoenix, room 128. Jonathan Davis Download Full Image

The lecture series, now in its seventh year, is open to the general public and is free.

The theme for this year’s series is “Creativity and the Humanities.”

“Mapstory technology is a tool that enables groups to map all their recorded history from their own perspective and allows educators to provide students multidisciplinary means to review a topic with much more of its complexities; it provides us with a 21st century mode of communication and data storage,” said Mirna Lattouf, series organizer.

The School of Letters and Sciences provides students across ASU with the knowledge and skills to comprehend and effectively engage the changing world of the 21st century at local, national and global levels. Theory, creativity and applied learning are integrated as students build entrepreneurial opportunities both inside the university and their communities.

Davis is an ASU geographic information systems graduate student who also holds a bachelor’s in history and government, and a master's in history. Currently, he is a Fellow for the Inter Tribal Council of Arizona, Inc. in Phoenix.

“I will be showing students and members of the community how an interdisciplinary approach to storytelling can be a powerful research advantage,” Davis said. “It’s a way to make any story more relevant, visually engaging and interesting. A static bar graph or chart isn’t going to cut it anymore.”

Considered one of the nation’s premiere storytellers, Davis creates visual stories through MapStory, an online platform that allows users to “organize knowledge about the world spatially and temporally.” His work on Florida sinkholes, diplomatic posts in China, congressional shifts in America and Native American treaties has been featured in the Washington Post, Arizona Republic, Business Insider, KTAR and the Lakota Times.

“When people look at charts and graphs, it doesn’t really impact them,” Davis said. “What I try and do is tie data by using MapStory to show where they do fit into the story. It’s a method to make the information exciting to readers.”

The lecture series will conclude on Nov. 6 with “Creativity and the Humanities,” a presentation by Patricia Colleen Murphy, founding editor of ASU Superstition Review.

Rapid interventions key to preventing Ebola outbreak


October 9, 2014

To avoid the spread of Ebola and far worse scenarios, quick and forceful implementation of control interventions are necessary, according to new research published Oct. 9 in the scientific journal Eurosurveillance.

Analyzing Ebola cases in Nigera, a country that has had success in containing the disease, researchers estimated the rate of fatality, transmission progression, proportion of health care workers infected and the impact of control interventions on the size of the epidemic. figure of transmission of the ebola virus, July-Sept. 2014 Download Full Image

The study's findings show that Ebola transmission is dramatically influenced by how rapidly control measures are put in place.

"Rapid and forceful control measures are necessary, as is demonstrated by the Nigerian success story," said Arizona State University's  Gerardo Chowell, senior author of the paper. "This is critically important for countries in the West African region that are not yet affected by the Ebola epidemic, as well as for countries in other regions of the world that risk importation of the disease."

Chowell is an associate professor in the School of Human Evolution and Social Change in the College of Liberal Arts and Sciences.

Control measures in Nigeria

The largest Ebola outbreak to date is ongoing in West Africa, with approximately 8,011 reported cases that include more than 3,857 deaths as of Oct. 5. However, just 20 Ebola cases have been reported in Nigeria, with no new cases reported since Sept.5.

All of the cases stem from a single traveler returning from Liberia in July.

The study used epidemic modeling to project the size of the outbreak in Nigeria if control interventions had been implemented during various time periods after the initial case, and estimated how many cases had thus been prevented by early initiation of interventions.

Control measures enacted in Nigeria included all people showing Ebola symptoms being held in an isolation ward if they had contact with the initial case. Once Ebola was confirmed through testing, people with Ebola were moved to a treatment center.

Asymptomatic individuals were separated from those showing symptoms, and those who tested negative without symptoms were discharged. People who tested negative, but showed symptoms – fever, vomiting, sore throat and diarrhea – were observed and discharged after 21 days if they were free of symptoms, while being kept apart from people who tested positive for the disease.

"The swift control of the outbreak in Nigeria was likely facilitated by early detection of the initial case in combination with intense tracing efforts of all subsequent contacts that the person had after developing Ebola," said Folorunso Oludayo Fasina, a senior scientist and lead author of the study at the University of Pretoria, South Africa.

"By contrast, the initial outbreak in Guinea remained undetected for several weeks, facilitating the spread of the virus to Sierra Leone and Liberia, where the inability to track and contain infectious individuals compounded the situation and resulted in an uncontrolled epidemic," said the lead author.

Brief window of opportunity

Ebola transmission is dramatically influenced by how rapidly control measures are put in place, as researchers found that the projected effect of control interventions in Nigeria ranged from 15-106 cases when interventions are put in place on day 3; 20-178 cases when implemented on day 10; 23-282 cases on day 20; 60-666 cases on day 30; 39-1599 cases on day 40; and 93-2771 on day 50.

"There is brief window of time when a rapid and forceful intervention in terms of relentless contact tracing and isolation pays off handsomely and the transmission is effectively halted and the outbreak dies out," said co-author professor Lone Simonsen, of the Milken Institute School of Public Health at the George Washington University in Washington D.C.

The person who was initially infected generated 12 secondary cases, in the first generation of the disease; five secondary cases were generated from those 12 in the second generation; and two secondary cases in the third generation, leading to a rough empirical estimate of the reproduction number according to disease generation declining from 12 during the first generation, to approximately 0.4 during the second and third disease generations. Recent estimates of the reproduction number for the ongoing Ebola epidemic in Sierra Leone and Liberia range between 1.5 and 2 (two new cases for each single case), indicating that the outbreak is yet to be brought under control.

"The effectiveness of the Nigerian response is illustrated by a dramatic decrease in the number of secondary cases over time. Overall, this is a great success story for Nigeria, which sets a hopeful example for other countries, including the U.S., which face risk of importation from high Ebola transmission areas," said Cécile Viboud, a National Institutes of Health scientist with the Fogarty International Center.
