Title:                   Using Online Social Media to Study Public Health

 

 

 

Abstract:              Every day, millions of people share what they are thinking and doing on social networks such as Twitter and Facebook. This talk will show how computational tools and models can be used to learn about the health of people based on what they share on social networks, in aggregate. For example, more people tweet that they are sick during heightened influenza activity, so Twitter feeds can be used to approximate flu prevalence in a population. This type of insight is the basis for an emerging scientific discipline called computational epidemiology. Besides influenza, tweets can be used to analyze trends in diet and exercise habits, sleep patterns, seasonal allergies, medication usage, and perceptions of healthcare quality. This talk will survey the variety of health topics that can be studied through social media feeds.

Title:                  The Coastal Anthropocene

 

 

 

Abstract:             Humans have always settled near estuaries and coastal seas, and are highly concentrated near the coast to this day. Human activity has fundamentally changed the biology, geology and hydrology of the coasts through the decline of some species and the introduction of other species, redistribution of sediments, nutrient enrichment and land reclamation. The scale of these impacts has grown to include planet-wide changes such as sea level rise. It is wise to recognize that the present options for managing coastal systems are constrained by past practices, just as future options depend on the decisions we make today.

Speaker:             Dr. Jim Jenness, Transportation and Safety Research Group, Westat

 

Title: Playing in Traffic: Designing On-Road Experiments to Understand Drivers’ Behavior

Abstract: Over the years, improvements in vehicle engineering have greatly improved crash survivability. Despite this, there are still more than 30,000 roadway fatalities in the United States each year. The safety focus in the U.S. has turned from an emphasis on crash worthiness to crash avoidance technologies and drivers’ behaviors. Behavioral studies are often conducted using driving simulators. Simulated worlds are safe and offer good experimental control, but they lack the richness and complexity of the real traffic environment. In this presentation, Dr. Jenness will discuss how he and his colleagues have used public roadways as a laboratory to study human factors issues related to motorcycle conspicuity, in-vehicle voice control systems, and next generation crash avoidance systems. 

Biography: Dr. James Jenness is a Sr. Research Scientist in the Transportation and Safety Research group at Westat (Rockville, MD). He earned a Ph.D. in Psychology (Biopsychology) from University of Michigan followed by postdoctoral research on visual perception at University of Chicago.  His career has included teaching courses in Psychology and Statistics at the College of Wooster, and designing user interfaces for telecommunications products such as voicemail and messaging systems. Since joining Westat in 2003, his research has focused on the ways in which the safety and comfort of transportation system users (drivers, passengers, and pedestrians) are influenced by the introduction of new technologies. He has directed research projects for clients such as the National Highway Traffic Safety Administration, Federal Highway Administration, Washington Area Metropolitan Transit Administration, Federal Railroad Administration, and the Insurance Institute for Highway Safety. Dr. Jenness is an active member of Human Factors and Ergonomics Society, Transportation Research Board, Society of Automotive Engineers International, and Association for the Advancement of Automotive Medicine.

Speaker:          Dr. J. Carson Smith, Assistant Professor and Director of the Exercise 

                                 for Brain Health Laboratory, Department of Kinesiology, University of

                                 Maryland.

 

Title:   Exercise and Brain Health

 

Abstract:  Among the multiple cognitive changes that occur across the lifespan, declining memory function is the most common complaint of otherwise healthy older adults.  The prevalence of cognitive impairment among older adults in the U.S. is estimated to be over 20 percent and, with an aging U.S. population, cognitive impairment and Alzheimer’s disease (AD) constitute an alarming public health problem. Interventions, including modifiable lifestyle behaviors such as physical activity, that even modestly delay the onset of cognitive impairment or help maintain cognitive function in older adults may slow the development of AD and could have a major public health impact.  This talk will highlight what we currently know about who is at increased risk for AD and will review the evidence for exercise to preserve brain function and possibly prevent AD.

 

Biography: Dr. J. Carson Smith is an Assistant Professor in the Department of Kinesiology at the University of Maryland and Director of the Exercise for Brain Health Laboratory.  His research is focused on understanding how acute and chronic exercise and physical activity affect human brain function and mental health related to cognition, memory, and emotion.  Dr. Smith uses multi-modal magnetic resonance imaging (MRI) to examine brain function in healthy younger adults, healthy older adults, and in people at increased risk for Alzheimer's disease.  In addition, Dr. Smith examines how acute and chronic exercise or physical activity may alter mood states, emotional reactivity, and attention allocation.

Speaker:       Dr. Jim Hagberg

 

Title:            Exercise: Just How Good Can it Be?

 

Abstract:      The health aspects of exercise are frequently in the news, both the good and bad sides. A number of years ago a University of Chicago president said “when I feel like exercising, I lay down until the feeling passes”. Is that the correct approach? Or do you need to become a marathon runner to reap the benefits of exercise? I will present evidence from a wide range of sources as to the “benefits” of exercise, in terms of mortality and the risk factors predisposing individuals to diseases that lead to premature mortality. The amount and intensity of the exercise will also be discussed, along with the benefits of different types of exercise. The primary disease entities that will be addressed are cardiovascular disease, type 2 diabetes, and obesity, along with some information concerning sarcopenia, falls, and cognitive decline.  Hopefully these results will motivate you to begin “exercising” if you are not already, prove to you that your current exercise program is the correct one for you, or provide you with some insights concerning how you might improve your “exercise” program. 

 

Bio:               Dr. Jim Hagberg is a Professor of Kinesiology at the University of Maryland College Park and a Professor of Medicine at the University of Maryland Baltimore School of Medicine. He is also a University of Maryland Distinguished Scholar Teacher and has won a number of awards for his research and mentoring. He is a life-long Badger Cheesehead and received his PhD degree in 1976 from the University of Wisconsin. He then completed an NIH Postdoctoral Fellowship at the Washington University School of Medicine in St. Louis. He then joined the faculty at Washington University and he has also been on the faculties of UCLA, Johns Hopkins University, University of Florida, and the University of Pittsburgh. He has now been on the faculty at the University of Maryland for 20+ years. He lives in a log home in Columbia, Maryland with 5 kayaks in the garage and 1000 acres of environmentally-protected lands right off his deck. His 250+ publications have assessed the benefits of exercise, especially for older individuals, and he has primarily focused on the cardiovascular system. His studies have addressed the effect of exercise training on blood pressure, insulin resistance, glucose tolerance, body composition, cardiovascular function, plasma lipoprotein-lipids, and markers of inflammation, fibrinolysis, and coagulation. He has been funded by NIH for the past 15+ years and is currently the Principal Investigator on 5 NIH grants. He has also been as Assistant Track and Cross Country coach at the University of Maryland and he has a company that develops phone apps for athletes, Training Optimization System, LLC.

Speaker:       Dr. Geoffrey “Jess” Parker, Senior Scientist, Smithsonian Environmental

                       Research Center 

 

Title:             Evidence for a Recent Growth Increase in Eastern Forests - A Response to

                       Climate Change?

 

Abstract:       Recent studies have shown increases in biomass across many forest types.  Often, this increase has been attributed to climate change.  However, since change in biomass can reflect normal recovery from previous events, it is important to know the disturbance history of a forest to understand the causes of change.  Using a unique dataset of tree biomass collected over the past 23 years from 55 temperate forest plots with known land-use histories and stand ages ranging from 5 to 250 years, we found that recent biomass accumulation greatly exceeded the expected caused by natural recovery.  Long records of local weather and of on-site atmospheric CO2 measurements showed increases consistent with globally observed climate-change patterns. Combined, these observations suggest that changes in temperature, growing season length and CO2 that have been observed worldwide can fundamentally alter the rate of critical natural processes.

 

Biography:    Since 1987 Geoffrey (‘Jess’) Parker has been the forest ecologist at the Smithsonian Environmental Research Center (SERC) in Edgewater, MD.   Before that, he attended McGill University where he received his undergraduate degree in Biology.  He subsequently earned his MS in Environmental Science from the University of Virginia and his Ph.D in Ecology from the University of Georgia.  He conducted his postdoctoral work as an associate at the Institute of Ecosystem Studies in Millbrook, NY.  His research interests concern the structure and function of forest ecosystems at long temporal and large spatial scales, in the canopies of forests, in the spatial relationships of forest trees, and in comparative forest ecology.   An organizing theme of the majority of his studies has been: the interaction between the structure of the forest canopy and exchanges of material and energy with the atmospheric boundary layer, the forest microclimates, and  biotic habitats.  He is currently involved in a variety of LIDAR-based studies of forest structure, eddy covariance-based measures of forest functions, and biometrically-based studies of forest carbon budgets.

Title:             The Magnetic Musculature of Space 

 

Speaker:        Thomas E Moore, Sr. Project Scientist for MMS, Heliophysics Science

                        Division, NASA's Goddard Space Flight Center  

 

Abstract:        We all know magnets exert forces, but did you know that magnetic fields act like muscles that connect celestial objects to each other? Magnetic muscle connections are switched by a process called "reconnexion," which thereby controls energy flow in space. The "brains" of reconnexion are believed to lie in thin boundaries and along a curve where field lines are either connected or disconnected, creating a portal for energy storage or release. The NASA MMS mission will let us observe how, when and where the magneto-muscular switch occurs and why it is often explosive, especially when one plasma tears free of another.  Like the scientists in the movie Twister, NASA will place the four MMS spacecraft right where the action is to obtain our first direct knowledge of the most violent and twister-like region in space plasmas, which regulates space weather in geospace. 

 

Biography:  Dr. Thomas E. Moore is Sr. Project Scientist for MMS, in the Heliophysics Science Division at NASA’s Goddard Space Flight Center. He earned a Ph.D. in Astrogeophysics from the University of Colorado, Boulder, in 1978 and did postdoctoral work at the University of NH, before joining NASA at the Marshall Space Flight Center in 1983. His research interests span the origin, evolution, and fate of our solar system, with a focus on the observed interplay between the atmospheres of the sun, planets and the interstellar medium. He has participated in several sounding rocket investigations of the aurora, was principal investigator for the Thermal Ion Dynamics Experiment on the NASA Polar Mission, and lead investigator for the Low Energy Neutral Atom imager on the IMAGE Mission, for which he was also the Mission Scientist. He was the Study Scientist for the Magnetospheric Constellation mission, has authored or co-authored over 250 research publications, and has served as an associate editor of refereed journals. He has served on several definition teams, review panels and strategic studies, including the Solar Probe Science and Technology Definition Team, the Sun Earth Connection Advisory Subcommittee (SECAS), and the Sun-Earth Connections Roadmap Team (1997, 2000). He co-chaired the first Heliophysics Roadmap Team in 2005-2006. He has been active in the American Geophysical Union as an Awards Committee member, as a Chapman Conference Convener, as a Program Secretary for Space Physics and Aeronomy, and was elected a Fellow of the AGU in 2009. He has received NASA awards for Excellence in Research and Technology, for membership in the Polar and IMAGE development teams, for Outstanding Management of the Interplanetary Physics Branch at NASA Goddard, and the NASA Exceptional Service Medal.

Speaker:         Peter Berulf Johnsen; The Great Salmon Tour

 

Abstract:        Though the concept of biodiversity and ecosystem preservation has found its way into mainstream media and public awareness, it continues to be an abstract concept for most people. But as we lose biodiversity, we lose some of our heritage - and not in an abstract way. In few other species is this more evident than for the different species of salmon.

Oysters – Can We Bring Them Back?

Denise Breitburg, Smithsonian Environmental Research Center

Peak oyster harvests in Chesapeake Bay occurred in the late 1800s. Since that time, oyster harvests and oyster populations in the Bay have declined. Although the major cause of the demise of oysters has been overfishing, water quality and disease have contributed to the problem in recent years and complicate efforts to restore oysters.  Until recently, oyster restoration efforts in Maryland were not conducted in a systematic way allowing for clear evaluations of success or failure of various strategies, and continued fishing negatively affected the ecological benefits of restoration efforts. Recent planning and implementation of large scale restoration efforts hold promise for success. It took over a hundred years of intense human activity to get to the current state, and restoration is occurring in a much different Bay than the one the oyster inhabited historically. Even a concerted, well planned effort will not instantly transform Bay oyster populations into the navigation hazards early European explorers once described.

Drought: Tools, Methods, Assessment, and Impacts; A Drought-Monitor Author’s Perspective

Eric Luebehusen, USDA, Office of the Chief Economist

Assessing drought in the United States — as well as across the Globe— is a challenging endeavor due to the multitude of timescales, data types, and impacts.  The US Drought Monitor attempts to assemble these into a singular easy-to-interpret product that has recently been a steady feature on nightly news broadcasts.  What most people see is a simple depiction of varying degrees of drought, but what goes on behind the scenes is a complicated, highly cooperative process that involves not only the author but a multitude of local, state, regional, and national-level agencies offering input on a weekly basis.
