Improving Health Behaviors Through Community Engagement: Challenge For A Healthier Louisiana, Stephanie T. Broyles, Elizabeth A. Gollub, Allison Tohme, Peter T. Katzmarzyk

Faculty Publications

There is increasing recognition that community-based approaches may have merit in improving physical activity and healthy eating behaviors. The “Challenge for a Healthier Louisiana” program supported twelve projects that addressed the root causes of obesity through integrated community-level changes. Partnerships provided community-based obesity prevention by promoting healthier eating and/or physical activity through enhanced infrastructure, policy changes, and programming. To evaluate whether the program resulted in changes in healthy eating and/or physical activity among adults, surveys were conducted pre- and postintervention among participants. Participants who were exposed to physical activity programs were more likely to adopt the consumption of fruits (odds …

Assessing Salvinia Molesta Impact On Environmental Conditions In An Urban Lake: Case Study Of Lago Las Curias, Puerto Rico, Charles F. Wahl, Rodrigo Diaz, Jorge Ortiz-Zayas

Faculty Publications

Giant salvinia (Salvinia molesta Mitchell, Salviniaceae) is a free-floating fern native to Brazil that alters natural processes in aquatic ecosystems, causing ecological problems for water resource managers. Due to its ease of dispersal through fragmentation and rapid growth, giant salvinia can quickly become problematic, requiring persistent management efforts. If left unmanaged, giant salvinia creates a thick mat of vegetation, which limits sunlight penetration, reducing aquatic macrophytes, lowering dissolved oxygen and stressing aquatic organisms. Giant salvinia was first reported in Lago Las Curias, Cupey, San Juan, Puerto Rico, USA, in 2016 and covered the entire 19 ha waterbody in 2018. In …

Recently, it has been widely accepted by the research community that interactions between humans and cyber-physical infrastructures have played a significant role in determining the performance of the latter. The existing paradigm for designing cyber-physical systems for optimal performance focuses on developing models based on historical data. The impacts of context factors driving human system interaction are challenging and are difficult to capture and replicate in existing design models. As a result, many existing models do not or only partially address those context factors of a new design owing to the lack of capabilities to capture the context factors. This …

Additive Schwarz Preconditioners For A Localized Orthogonal Decomposition Method, Susanne C. Brenner, José C. Garay, Li Yeng Sung Jan 2020

Additive Schwarz Preconditioners For A Localized Orthogonal Decomposition Method, Susanne C. Brenner, José C. Garay, Li Yeng Sung

Faculty Publications

We investigate a variant of the localized orthogonal decomposition method (Henning and Peterseim, [Multiscale Model. Simul., 11 (2013), pp. 1149 1175] and Malqvist and Peterseim, [Math. Comp., 83 (2014), pp. 2583 2603]) for elliptic problems with rough coefficients. The construction of the basis of the multiscale finite element space is based on domain decomposition techniques, which is motivated by the recent work of Kornhuber, Peterseim, and Yserentant [Math. Comp., 87 (2018), pp. 2765 2774]. We also design and analyze additive Schwarz domain decomposition preconditioners for the resulting discrete problems.

Running Local: Gender Stereotyping And Female Candidates In Local Elections, Nichole M. Bauer Jan 2020

Running Local: Gender Stereotyping And Female Candidates In Local Elections, Nichole M. Bauer

Faculty Publications

An implicit assumption underlying the gender stereotyping literature is that female candidates have an advantage in local elections. Two factors motivate this assumption. First, some local issues, such as the provision of social services, fit into the stereotypic strengths of female politicians. Second, as the level of office increases, so too does the perceived masculinity of the office. Research on local policymaking, however, indicates that the tasks associated with local political offices, such as economic competition with other cites, require masculine rather than feminine qualities. I integrate research on local policymaking with the gender stereotyping literature to clarify the role …

Emissions of greenhouse gases (GHG) are linked to global warming and adverse climate changes. Meeting the needs of the increasing number of people on the planet presents a challenge for reducing total GHG burden. A further challenge may be the size of the average person on the planet and the increasing number of people with excess body weight. We used data on GHG emissions from various sources and estimated that obesity is associated with ~20% greater GHG emissions compared with the normal-weight state. On a global scale, obesity contributes to an extra GHG emissions of ~49 megatons per year of …

Gender Contexts, Dowry And Women's Health In India: A National Multilevel Longitudinal Analysis, Samuel Stroope, Rhiannon A. Kroeger, Jiabin Fan

Faculty Publications

Gender-biased contexts may impact women's lives across a variety of domains. This study examined whether changes in district prevalence of a salient gendered practice - dowry - are associated with changes in poor health for women in India. Two waves of national multilevel panel data were used to assess the relationship between changes in district-level dowry prevalence and changes in self-rated health for 23,785 ever-married women aged 15-50 years. Increased dowry prevalence was found to be associated with increased poor self-rated health for women. This relationship remained when controlling for potentially confounding factors including household socioeconomic status, caste, infrastructure, mobility …

She Came To Slay: The Life And Times Of Harriet Tubman, Hilary N. Green Jan 2020

She Came To Slay: The Life And Times Of Harriet Tubman, Hilary N. Green

Civil War Book Review

For an extraordinary historical figure, Dunbar offers an accessible and multidimensional biography of Harriet Tubman Ross and renders her as a complex “a true boss lady, a superhero, and a warrior” in She Came to Slay (xii).Organized chronologically, Dunbar opens with a discussion of Tubman’s grandmother Modesty who “planted a seed of resilience in her progeny that would blossom even in her absence (6-7).” Acknowledging the scant archival record, Dunbar establishes the familial roots contributing to Tubman’s fortitude and character. Although offering freedom to her daughters and granddaughter in his will, Pattison’s daughter and her husband, however, ignored this …

Role Of Geometric Shape In Chiral Optics, Philipp Gutsche, Xavier Garcia-Santiago, Philipp Immanuel Schneider, Kevin M. Mcpeak, Manuel Nieto-Vesperinas, Sven Burger

Faculty Publications

The distinction of chiral and mirror symmetric objects is straightforward from a geometrical point of view. Since the biological as well as the optical activity of molecules strongly depend on their handedness, chirality has recently attracted high interest in the field of nano-optics. Various aspects of associated phenomena including the influences of internal and external degrees of freedom on the optical response have been discussed. Here, we propose a constructive method to evaluate the possibility of observing any chiral response from an optical scatterer. Based on solely the T-matrix of one enantiomer, planes of minimal chiral response are located and …

Reachable Sets For Safe, Real-Time Manipulator Trajectory Design, Patrick Holmes, Shreyas Kousik, Bohao Zhang, Daphna Raz, Corina Barbalata, Matthew Johnson-Roberson, Ram Vasudevan

Faculty Publications

For robotic arms to operate in arbitrary environments, especially near people, it is critical to certify the safety of their motion planning algorithms. However, there is often a trade-o↵ between safety and real-time performance; one can either carefully design safe plans, or rapidly generate potentially-unsafe plans. This work presents a receding-horizon, real-time trajectory planner with safety guarantees, called ARMTD (Au-tonomous Reachability-based Manipulator Trajectory Design). The method first computes (o✏ine) a reachable set of parameterized trajectories for each joint of an arm. Each trajectory includes a fail-safe maneuver (braking to a stop). At runtime, in each receding-horizon planning iteration, ARMTD constructs …

Wettability Effects On Primary Drainage Mechanisms And Napl Distribution: A Pore-Scale Study, Ian L. Molnar, Jason I. Gerhard, Clinton S. Willson, Denis M. O'Carroll

Faculty Publications

The pore-scale processes governing water drainage behavior in porous media have implications for geoscience multiphase scenarios including carbon capture and storage, contaminant site remediation, oil recovery, and vadose zone processes. However, few studies report directly observed pore-scale water drainage phenomena in 3-D soils. This knowledge gap limits our ability to verify assumptions underlying existing models and develop optimal solutions. This paper utilizes synchrotron X-ray microtomography to present an experimental pore-scale examination of nonaqueous phase liquid (NAPL)/water distribution along a primary drainage front as dense NAPL was injected upward into water wetting (WW) and intermediate wetting (IW) sand-packed columns. Pore-network structures …

Industry Versus Government Regulation Of Food Date Labels: Observed Adherence To Industry-Endorsed Phrases, Brian E. Roe, Danyi Qi, Kathryn E. Bender, Julia Hilty

Faculty Publications

© 2019 by the authors. A leading factor in the creation of avoidable household food waste is confusion about food date labels. In the United States, date labels are largely unregulated, resulting in a plethora of date label phrases used in commerce. Federal regulation has been proposed but never passed, while both industry and government have provided voluntary guidance on preferred label phrases. We study food producer adherence to the label phrases endorsed by the Trading Partner Alliance (TPA, an industry group), which includes "Use By" for perishable products subject to a material degradation of critical performance or potential food …
