Stephen Angle, Mansfield Freeman Professor of East Asian Studies, professor of philosophy, has had a number of recent publications.
Angle is the editor of “The Adolescence of Mainland New Confucianism,” special issue 49:2 of Contemporary Chinese Thought (2018). The issue is devoted to recent mainland Chinese Confucian philosophizing, and particularly to arguments about what “Mainland New Confucianism” signifies, which were prompted by noted Taiwanese scholar Li Minghui’s 2015 remarks about Mainland New Confucianism.
Angle also wrote an introduction to the issue, which explores how Mainland New Confucianism has entered a somewhat more diverse and mature stage than previously. The introduction also reflects on the place of Confucianism within contemporary East Asia.
Earlier this year, Angle authored the article “Does Confuscian Public Reason Depend on Confucian Civil Religion?”, which was published in the Journal of Social Philosophy. The article focuses on a dimension of the increasingly pluralist field of political philosophy, in which Western and non‐Western theories and experiences are reevaluated in light of one another.
In addition to these publications, Angle is a contributor to and co-administrator of Neo-Confucianism, a companion website for Angle’s book, co-authored with Justin Tiwald, Neo-Confucianism: A Philosophical Introduction (2017); and Warp, Weft, and Way, a group blog focused on on Chinese and comparative philosophy.
Besides his research and teaching responsibilities, Angle also serves as the director of the Fries Center for Global Studies. He is a principal investigator on the “Wesleyan South Asia Initiative,” a grant awarded by the US Department of Education’s Undergraduate International Studies and Foreign Language program (2018–2020).

The rare Guadalupe fescue once thrived in abundance atop mountains spanning the Texas-Mexico border, however, the desert-growing perennial grass is now so endangered, it only flourishes in two locations on Earth.
The rapid population decline is leaving scientists puzzled.
“Developing an effective recovery plan is essential for protecting Guadalupe fescue, however, the lack of basic information about this species’ ecology is a serious barrier to that goal,” explained Helen Poulos, adjunct assistant professor of environmental studies. “Urgent action is needed to stabilize the two extant populations.”
This summer, under Poulos’s leadership, Wesleyan received a National Park Service Grant to study Festuca ligulata through the Southwest Borderlands Resource Protection Program. She joined a bi-national team of scientists known as “Fescue Rescue” to research the two isolated fescue populations in Texas’s Big Bend National Park and the Maderas del Carmen Protected Area in Coahuila, Mexico.
Said Poulos, a plant ecologist who has worked at desert borderland sites for more than a decade, “The Guadalupe fescue has become so endangered that this has become a significant national and international conservation concern.”
Backed by the NPS grant, the Fescue Rescue team will conduct onsite visits from October to mid-November 2019 during Guadalupe fescue seed maturation. Seeds will be collected during this time and transported to labs at Sul Ross State University in Texas and Universidad Autónoma Antonio Narro in Mexico. At these locations, scientists will germinate the seeds and grow their own fescue refugial populations for multiple research purposes.
“Together, they’ll provide a springboard for future plant population genetics, enrichment planting, and adaptive management research on both sides of the border,” Poulos said. “Such information is vital for elaborating site-specific management plans for the species on both U.S. and Mexican soils.”
They’ll study environmental variables, inventory seed production, identify key factors that promote reproductive viability, and ultimately establish refugial populations on both sides of the border.
Although virtually nothing is known about the environmental influences on the growth and reproduction of Guadalupe fescue, Poulos believes the fescue’s population decline is a result of multiple factors.
“Environmental factors that have likely negatively influenced the fescue populations include a recent shift to a hotter and drier climate, the genetic and demographic consequences of small population sizes and isolation, trampling by humans and pack animals, trail runoff, competition from invasive species, and fungal infection of seeds,” she said.
In addition, naturally occurring wildfires, which play an important role in rejuvenating ecosystems, are rare due to livestock grazing in the early 1900s and subsequent direct fire suppression continuing to the present. The remaining plants in the two disjunct populations are likely highly inbred and lack genetic diversity. This can threaten the capacity of populations to resist pathogens and parasites, adapt to changing environmental conditions, and colonize new habitats.
Poulos hopes to deliver her final reports to the National Park Service by summer 2020.

A new collaborative research hub, supported by Wesleyan’s Quantitative Analysis Center, provides faculty and students with the tools to prepare, analyze and disseminate information on movement, travel and communication in easily-accessible formats.
The Traveler’s Lab, developed by faculty members Gary Shaw, Jesse Torgerson and Adam Franklin-Lyons at Marlboro College, connects the faculty with each others’ projects, but also with students who are interested in an interdisciplinary approach to historical research.

Mike Robinson, assistant professor of psychology, is a co-author of a paper titled “The impact of junk-food diet during development on ‘wanting’ and ‘liking’.” The paper was recently published in The Behavioral Brain Research Journal. His co-authors include Wesleyan alumni Ellen Nacha Lesser ’15, Aime Arroyo-Ramirez ‘16, and Sarah Jingyi Mi ’16.
The research looked at the developmental impacts of a chronic junk-food diet throughout development and how it blunts pleasure and affects motivation. The study found that chronic exposure to a junk-food diet resulted in large individual differences in weight gain (gainers and non-gainers) despite resulting in stunted growth as compared to chow-fed controls. Behaviorally, junk food exposure attenuated conditioned approach (autoshaping) in females, particularly in non-gainers. In contrast, junk-food exposed rats that gained the most weight were willing to work harder for access to a food cue (conditioned reinforcement), and were more attracted to a junk-food context (conditioned place preference) than non-gainers.

Four Wesleyan academic departments, from psychology to dance to chemistry to biology, are competing for grant funds through a new crowdfunding site specifically designed for research project fundraising.
Experiment.com’s Challenge Grant for Liberal Arts Colleges asked scientists to define a scientific research question for the crowd with a prize for the project with the most backers. The pilot launched on Feb. 24 and concludes March 25.During this 31-day period, the goal is to reach $4,000 in funding. If so, the team is granted the money. If not, they receive nothing and no one’s pledges are charged. By backing a project, participants will receive updates, results and data from project creators.
Wesleyan research include how the brain prevents risky-decision making/addiction; the effects of using artificial sweeteners; controlling seizures with light; and the effectiveness of somatic mind-body practices on victims of the war.
On Wednesday, March 16 at 11:59 p.m., Experiment will award the project with the most backers $2,000 directly through their project page.
Wesleyan’s projects include:

Johan “Joop” Varekamp, the Howard T. Stearns Professor in Earth Science, led an invited talk at the American Geophysical Union (AGU) meeting in San Francisco, Dec. 2015.
The earth and space science community participated in discussions of emerging trends and the latest research. The session, which was co-authored by former Wesleyan E&ES graduate student Lauren Camfield, focused on the 2012 eruption of the Copahue volcano in Argentina.
Due to the success of the invited talk on Volcanic Hydrothermal Systems, Varekamp will be a co-editor for a special issue of a journal based on that session. As part of his role as chair-elect of the Committee on Geology and Public Policy of the Geological Society of America (GSA), he will be interviewing five candidates in Washington D.C. for the position of congressional fellow.

Research Professor Ellen Thomas grasps a glass-enclosed sample of hundreds of microfossils, each a white fleck of limestone barely visible to the human eye.
“The first time students look at these they say, ‘they all look the same to me,’ but in reality, they are all have very different shapes,” Thomas says. “Even under a microscope, it can be difficult for a new eye to see the differences, but each species has its own shape; some have a much more open, light structure because they lived floating in the oceans close to the surface. Others have denser shells and lived on the bottom of the ocean, or within the mud. And each one can tell us, in its chemical make up, what the environmental conditions were like at the time that they lived and built their shells.”
By studying and analyzing microfossils, Thomas and fellow scientists are able to explore aspects of climate change on a variety of timescales,

It turns out that teaching language arts, math and science to fourth graders is not the same as manufacturing cars on an assembly line. That is, the microeconomics principle of economies of scale—or the cost advantages that businesses get by increasing the scale of production—do not always apply to educational interventions.
Put another way, an intervention that works great in one specific educational setting cannot necessarily be “scaled up” to work in many other settings.
This is the finding of a major new study funded by the National Science Foundation, on which Associate Professor of Psychology Steven Stemler collaborated with colleagues at a number of other universities including Yale, Cornell and the University of Sydney. The study, carried out in 223 classrooms across the country in the early- to mid-2000s, was published in the American Psychology Association’s Journal of Educational Psychology in August. The paper is titled “Testing the Theory of Successful Intelligence in Teaching Grade 4 Language Arts, Mathematics, and Science.”

Thanks to NASA, two Earth and Environmental Science faculty are going to spend the better part of their next three summers on Venus looking at volcanoes and mountain ranges.
Specifically, Martha Gilmore, associate professor of earth and environment science, and Phillip Resor, assistant professor of earth and environmental science, will be using a three-year NASA grant to examine an area of Venus called the Tellus Regio, which is contains some of the oldest rocks on the planet’s surface.
“It’s an area of interest for two reasons, primarily,” says Gilmore, who has done work on Mars and Venus missions, among others for NASA’s Jet Propulsion Laboratory (JPL). “First, it’s an area that is high on NASA’s list of
