How ASU is helping admitted students find their way via Slack

Devil2Devil, ASU’s private network for admitted students is now integrated with Slack, allowing the new learners to gather virtually

June 17, 2020

For new students, the idea of going to an unfamiliar place can be daunting, and this has only been compounded by the pandemic. ASU has long believed in the power of community to address the potential concerns of settling into a new life in a new place. That’s why Devil2Devil exists: for incoming students to find friends, look for roommates, ask questions and get information about enrollment steps and other processes.

Devil2Devil has existed in one form or another since 2011, and past iterations have looked and felt very much like a social network. Some have needed Facebook authentication in order to join. But in 2019, even before the novel coronavirus exploded onto the global scene, it was clear that a paradigm shift was needed to get students active and engaged. Students no longer used Facebook as frequently as they had in years past.  students wearing gold shirts standing on "A" Mountain Download Full Image

Casey Thomas, associate director of digital engagement and public relations of admission services and Devil2Devil’s community manager since its inception, said, “We knew students weren’t really looking for another social network, so it was appropriate to move Devil2Devil into a space specific to ASU.” And so in May 2019, Thomas began talking with the University Technology Office about moving Devil2Devil to its new home as part of ASU’s Slack Enterprise Grid.

“Easy login access, a mobile app and customizable channels for conversations made Slack appealing,” said Thomas. And incoming students would now have prior exposure to the platform before using it for collaboration and coursework — a big advantage, considering the advent of Slack as the manifestation of ASU’s digital campus.

Devil2Devil is available to incoming first-year, transfer and master’s degree-level graduate students from about February to September, at which point students can continue collaborating and otherwise interacting with peers on Slack via direct messaging and other channels.

Usage data shows just how successful the move to Slack has been. Devil2Devil’s Slack presence launched Feb. 1, 2020, and it has 11,800 members as of June 9, 2020, with 2,300 active weekly users. Previous iterations of Devil2Devil have never surpassed 8,000 users.

Thomas also attributes some of the new Devil2Devil’s success with the pandemic, as admitted students have sought connection while largely isolated from the outside world. There was a significant jump in activity, for example, during the week of March 16, which for many was the first week of quarantine.

And the pandemic has impacted Devil2Devil programs as well. Just this month, Thomas and her team introduced New Student Orientation Gold Guides to Devil2Devil to host peer-led New2ASU channels with guided activities, content regarding enrollment and academic success and ASU resources. Thomas points to the success of this initiative, which would not have existed without the pandemic.

“The students hosting these channels are usually helping run in-person orientation programs and would not have been available to manage channels. And previous iterations had no effective way to create channels or groups like this,” she said.

Devil2Devil provides an invaluable service to admitted students. For some, it eases the transition of being away from home by introducing others from the same area. For others, it makes finding a roommate easier by letting users glimpse each other’s interests and personalities. However Devil2Devil is used, Thomas adds, “it’s instrumental in helping us build the sense of belonging for our admitted students.”

New data unveils ancestry of first peoples to inhabit Caribbean

93 ancient DNA samples solidify our understanding of how ancient people moved to and through the Caribbean

June 17, 2020

Researchers now have a better understanding of how the first people moved to and through the Caribbean. A new study published in ​Science​ recognizes at least three migrations of ancient people through the islands. Two early groups came to present-day Cuba from the mainland, and one came to what is now Puerto Rico and the Lesser Antilles from South America.

These discoveries came from analyzing 93 ancient Caribbean DNA samples spanning a time frame from 3,200 to 400 years ago. Samples were obtained with permission from excavations or existing collections of museums and universities.

Arizona State University researchers from the ​School of Human Evolution and Social Change contributed data and analysis from Puerto Rico. Anthropological geneticist and Regents Professor ​Anne Stone​ supervised the work of Maria Nieves-Colón, a doctoral student at the time and now a research affiliate of the school.

Nieves-Colón originally analyzed ancient Puerto Rican islander DNA during her graduate studies, publishing findings in ​Molecular Biology and Evolution. Researchers from the University of Copenhagen invited Nieves-Colón to collaborate on this larger study analyzing the ancestry of the Caribbean region. 

From the mainland

Historically, it has been unclear how and from where the first inhabitants of the islands arrived. Archaeologists have offered multiple theories based on pottery and other artifacts, but this study links together genetic data in a new way and provides a more detailed understanding of human movements in the area.

The first two migrations, during what is known as the Archaic Period, spanned approximately 3,000 to 1,000 years ago. The third major movement happened during the Ceramic Period when researchers saw evidence of elaborate ceramics being introduced to the Caribbean. The Ceramic Period occurred between 2,500 and 500 years ago.

To better analyze the actual movement of early peoples to and through the islands, researchers compared ancient DNA from specific sites in the Caribbean to DNA found at other sites around the world for similarities. Evidence from the first migrations suggests an early colonization of present-day Cuba from the mainland. Although the precise origin of this migration is unclear, one ancient individual sampled from Cuba shares ancestry with ancient populations who lived on the California Channel Islands. Later migrations, during the Ceramic Period movement, saw people travel up from South America to Puerto Rico and the Lesser Antilles, according to the study.

Researchers were surprised to find that the waves of settlers seem to have kept their distance from each other.

“We would have expected to see that people who came after would have had a mix between the DNA of the early and later settlers, but we didn’t see that,” Nieves-Colón said.

Researchers do not know why this was the case, but more data would likely provide additional insights.

While the researchers found evidence of these three movements, Nieves-Colón cautions that people may have been in parts of the Caribbean even earlier. DNA analysis of older remains is often difficult.

Nieves-Colón used equipment in ASU’s ancient DNA lab to extract DNA from skeletal remains from Puerto Rico.

While the hot and moist environment of the Caribbean is not conducive to preserving ancient DNA, advances in technology over the last decade have led to increased accuracy and the ability to extract more DNA from a single sample. Looking at more and longer sequences of DNA provides results with higher levels of confidence.

Ethical, collaborative science

Stone and Nieves-Colón worked with archaeologists, agencies and the Puerto Rican Institute of Culture to obtain permission to conduct the research.

“When we work with ancient DNA, unfortunately, it’s generally a destructive process, so we are careful to complete the work ethically,” Nieves-Colón said.

She and her collaborators took extra steps as researchers cognizant of their work, including sending permission-granting institutions copies of the finished papers and returning remains that are intact after DNA extraction.

As a Puerto Rican, Nieves-Colón said, “It’s important for me to do this research right because they are my ancestors, too.”

Nieves-Colón is continuing her research on Puerto Rican DNA. She is interested in understanding the relationship between the ancient people of Puerto Rico and the people living there today.

“There’s been a narrative of the Native Americans in the Caribbean going extinct,” Stone said. “What you see in the DNA is that that’s not true, they exist, but they are mixed into the population today.”

The work for Nieves-Colón’s dissertation was funded by the National Science Foundation, the Rust Family Foundation for Archaeological Research and the School of Human Evolution and Social Change.
