Expressive Language Abilities Of Boys With Idiopathic Autism Spectrum Disorder And Boys With Fragile X Syndrome + Autism Spectrum Disorder: Cross-Context Comparisons, Elizabeth Hilvert, Audra Sterling, Eileen Haebig, Laura Friedman Jan 2020

Expressive Language Abilities Of Boys With Idiopathic Autism Spectrum Disorder And Boys With Fragile X Syndrome + Autism Spectrum Disorder: Cross-Context Comparisons, Elizabeth Hilvert, Audra Sterling, Eileen Haebig, Laura Friedman

Faculty Publications

Background and aims: Understanding the unique expressive language profiles of children with phenotypically similar, but distinct neurodevelopmental disorders, such as idiopathic autism spectrum disorder and fragile X syndrome with a co-diagnosis of autism spectrum disorder (fragile X syndrome + autism spectrum disorder), has both clinical and theoretical implications. However, comparative studies of these two clinical groups have been limited, and results have been inconsistent, partially as a result of different assessment methods being utilized. Thus, the current study compared the expressive language profiles of boys with idiopathic autism spectrum disorder and boys with fragile X syndrome + autism spectrum disorder …

Introduction To The Special Issue On English In The Southern United States: Social Factors And Language Variation, Irina Shport, Wendy Herd Jan 2020

Introduction To The Special Issue On English In The Southern United States: Social Factors And Language Variation, Irina Shport, Wendy Herd

Faculty Publications

The Southern United States have long been known for language diversity, yet linguistic research in this region has often focused on broad descriptions of characteristics of Southern American English as compared to other regional dialects of American English. Linguistic subregions in the South, however, are distinctly different from each other, and additional social variation also occurs within those subregions. Thus, the different English varieties spoken in the South cannot be collapsed under a single umbrella. Analyzing varieties of English in the Southern United States calls for a narrower approach, which will more accurately represent diverse Southern communities, their languages of …

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 …

Emerging Infectious Disease, The Household Built Environment Characteristics, And Urban Planning: Evidence On Avian Influenza In Vietnam, James H. Spencer, Melissa L. Finucane, Jefferson M. Fox, Sumeet Saksena, Nargis Sultana

Faculty Publications

Recent concerns with pandemic outbreaks of human disease and their origins in animal populations have ignited concerns regarding connections between Emerging Infectious Diseases (EID) and development. As disasters, health, and infectious disease become part of planning concern (Matthew & McDonald, 2007), greater focus on household infrastructure and EID disease outbreaks among poultry is warranted. Following Spencer (2013), this study examines the relationship between the mix of household-scale water supplies, sanitation systems, and construction materials, and Highly Pathogenic Avian Influenza (HPAI) among poultry in a developing country: Vietnam. Findings of our multivariate logistic regressions suggest that a non-linear, Kuznets-shaped urban transition …

The Environmental Foodprint Of Obesity, Faidon Magkos, Inge Tetens, Susanne Gjedsted Bügel, Claus Felby, Simon Rønnow Schacht, James O. Hill, Eric Ravussin, Arne Astrup

Clinical Research Faculty Publications

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 …

Evaluation Of Yield, Marketability, And Nitrate Levels Of Lettuce Cultivars Produced In Southern Louisiana, William D. Afton, Kathryn K. Fontenot, Jeff S. Kuehny, Carl E. Motsenbocker

Faculty Publications

Forty-five cultivars of lettuce (Lactuca sativa) were field-grown using best management practices at the Louisiana State University Agricultural Center (LSU AgCenter) Botanic Gardens in Baton Rouge during the Fall 2011 and Fall 2012 seasons. Recommended cultivars were selected for commercial production in Louisiana based on fresh weight and lettuce size (width and height). Nitrate (NO3– ) concentration was analyzed for each cultivar, as lettuces are known to accumulate and concentrate NO3–, and were then compared with the U.S. Environmental Protection Agency’s (EPA) oral reference dose (RfD—the EPA’s maximum acceptable oral dose of a toxic substance) of 1.6 mg NO3-nitrogen (N) …

Population and Public Health Science Faculty Publications

Objective. The aim of this study was to explore the association of 1,5-anhydroglucitol with acute C peptide response (ACPR) to arginine among patients with type 2 diabetes. Methods. Patients with type 2 diabetes were enrolled from the Department of Endocrinology and Metabolism, Shanghai Sixth People's Hospital. ACPR was assessed using arginine stimulation test. Decreased β-cell function was defined as ACPR< 2.1. Multivariable logistic regression models were used to demonstrate the association between 1,5-anhydroglucitol and decreased β-cell function. Results. Finally, 623 patients with type 2 diabetes were enrolled into the analysis. Multivariable-adjusted odds ratios for decreased β-cell function across quartiles of 1,5-anhydroglucitol were 1.00, 0.47 (95% confidence interval (CI) 0.23-0.99), 0.41 (95% CI 0.20-0.84), and 0.27 (95% CI 0.13-0.57) (Ptrend=0.042), respectively. When 1,5-anhydroglucitol was considered as a continuous variable after logarithm, the corresponding odds ratio was 0.40 (95% CI 0.23-0.71). Conclusions. We demonstrated a dose-response linear association between 1,5-anhydroglucitol and ACPR. 1,5-Anhydroglucitol was likely to be associated with β-cell function. Further analysis with large sample size and prospective study design is warranted to validate our findings.

Clinical Research Faculty Publications

The postnatal period is a critical phase in both the lives of the mothers and the newborns. Due to all the inherent changes that occur during this period, quality care is crucial during this period to enhance the wellbeing of the mothers and the newborns. In Morocco, the neglection of postnatal care services are often associated to poor communication, financial difficulties and cultural barriers. Mobile technology constitutes therefore a promising approach to bridge this gap and promote postnatal care. In order to improve the effectiveness of mobile technology, gamification has become a powerful feature to boost motivation and induce fun …

Boxed In: Beliefs About The Compatibility And Likability Of Mother-Occupation And Father-Occupation Role Combinations, Mary C. Noonan, Freda B. Lynn, Mark H. Walker Jan 2020

Boxed In: Beliefs About The Compatibility And Likability Of Mother-Occupation And Father-Occupation Role Combinations, Mary C. Noonan, Freda B. Lynn, Mark H. Walker

Faculty Publications

Researchers have long noted that role expectations of a “good” mother conflict with those of a “good” worker, described as the “cultural contradiction” of motherhood. But given that work roles vary tremendously in terms of the cultural meanings the public assigns them, the authors examine variability in the perceived compatibility of mother-occupation and father-occupation combinations. Building on previous research, the authors hypothesize that (1) some parent-occupation pairings will be viewed as significantly less compatible because of incongruent expectations and meanings, and (2) incumbents of supposedly compatible parent-occupation pairings will be evaluated more favorably than incumbents of incompatible pairings. Both hypotheses …

Seeking Competitive Advantage Through Platform-Enabled Resources: The Case Of Food Delivery Platforms, Joaquin Rodriguez, Gabriele Piccoli Jan 2020

Seeking Competitive Advantage Through Platform-Enabled Resources: The Case Of Food Delivery Platforms, Joaquin Rodriguez, Gabriele Piccoli

Faculty Publications

As digital platforms become increasingly ubiquitous, firms in a wide array of industries face the decision of whether to join them and how to compete within them. The information systems field is in a unique position to theorize and investigate how platform participants can use broadly available digital platform resources in order to achieve, and possibly sustain, competitive advantage. We empirically investigate the theoretical proposition that restaurants joining the food delivery digital platform can compete by leveraging a specific emergent capability we call platform-fulfillment capability. Our results indicate that differentiation and competitive advantage are possible, even though all platform participants …

The Battle Of The Wilderness In Myth And Memory: Reconsidering Virginia’S Most Notorious Civil War Battlefield, Chris Mackowski Jan 2020

The Battle Of The Wilderness In Myth And Memory: Reconsidering Virginia’S Most Notorious Civil War Battlefield, Chris Mackowski

Civil War Book Review

Being “lost in the Wilderness” is an existential experience as old as the Bible, and therefore it’s no surprise that no Civil War landscape has more metaphoric power than Virginia’s Wilderness. The 1864 battlefield offers a unique Civil War twist that writers have taken advantage of since they started writing narratives about the battle. But aside from Stephen Cushman’s 1999 Bloody Promenade, no writer has examined the mythic power of the Wilderness as a thing unto itself. Adam H. Petty’s systematic study, The Battle of the Wilderness in Myth and Memory, casts light into that dark foliage and, …

We utilize a nuclear shell model Hamiltonian with only two adjustable parameters to generate, for the first time, exact solutions for pairing correlations for light to medium-mass nuclei, including the challenging proton-neutron pairs, while also identifying the primary physics involved. In addition to single-particle energy and Coulomb potential terms, the shell model Hamiltonian consists of an isovector T=1 pairing interaction and an average proton-neutron isoscalar T=0 interaction, where the T=0 term describes the average interaction between nonpaired protons and neutrons. This Hamiltonian is exactly solvable, where, utilizing three to seven single-particle energy levels, we reproduce experimental data for 0+ state …

We present results from a semicoherent search for continuous gravitational waves from the low-mass x-ray binary Scorpius X-1, using a hidden Markov model (HMM) to track spin wandering. This search improves on previous HMM-based searches of LIGO data by using an improved frequency domain matched filter, the J-statistic, and by analyzing data from Advanced LIGO's second observing run. In the frequency range searched, from 60 to 650 Hz, we find no evidence of gravitational radiation. At 194.6 Hz, the most sensitive search frequency, we report an upper limit on gravitational wave strain (at 95% confidence) of h095%=3.47×10-25 when marginalizing over …

© 2019 The Royal Entomological Society 1. Interactions among herbivores mediated by plant responses to herbivore injury may have large impacts on herbivore population densities. Responses may persist for weeks after injury and may affect not only the initial (inducing) herbivore, but also herbivores that are spatially or temporally separated from the initial attacker. 2. In many plant–insect interactions, multiple life stages of the insect may be associated with the same plant, and these various stages may interact indirectly with one another via induced responses. The rice water weevil (RWW), Lissorhoptrus oryzophilus, a serious global pest of rice, is one …
