© 2018 by the authors. Licensee MDPI, Basel, Switzerland. Dendroecology is the science that dates tree rings to their exact calendar year of formation to study processes that influence forest ecology (e.g., Speer 2010 [1], Amoroso et al., 2017 [2]). Reconstruction of past fire regimes is a core application of dendroecology, linking fire history to population dynamics and climate effects on tree growth and survivorship. Since the early 20th century when dendrochronologists recognized that tree rings retained fire scars (e.g., Figure 1), and hence a record of past fires, they have conducted studies worldwide to reconstruct [2] the historical range …


Toward Understanding Posttraumatic Stress And Depression Among Trauma-Affected Widows In Sri Lanka, Jessica E. Lambert, Alyssa Banford Witting, Spencer James, Lakmal Ponnamperuma, Thulitha Wickrama May 2018

Toward Understanding Posttraumatic Stress And Depression Among Trauma-Affected Widows In Sri Lanka, Jessica E. Lambert, Alyssa Banford Witting, Spencer James, Lakmal Ponnamperuma, Thulitha Wickrama

Faculty Publications

Objective: In this study, we applied conservation of resources theory (Hobfoll, 1989) to explain high rates of depression and posttraumatic stress symptoms (PTSS) among war- and disaster-affected Tamil widows in the Eastern Province of Sri Lanka. We hypothesized exposure to potentially traumatic events and severity of current contextual problems would influence PTSS and depressive symptoms directly and indirectly through loss of psychological (view of self), environmental (sense of community), and energy (physical health) resources. Method: Trained research assistants interviewed a convenience sample (N = 381) of women, using established measures of the constructs of interest. Data were analyzed using …


Pedestrian Injury Severity Analysis In Motor Vehicle Crashes In Ohio, Majbah Uddin, Fahim Ahmed May 2018

Pedestrian Injury Severity Analysis In Motor Vehicle Crashes In Ohio, Majbah Uddin, Fahim Ahmed

Faculty Publications

According to the National Highway Traffic Safety Administration, 116 pedestrians were killed in motor vehicle crashes in Ohio in 2015. However, no study to date has analyzed crashes in Ohio in order to explore the factors contributing to the pedestrian injury severity resulting from motor vehicle crashes. This study fills this gap by investigating the crashes involving pedestrians exclusively in Ohio. This study uses the crash data from the Highway Safety Information System, from 2009 to 2013. The explanatory factors include the pedestrian, driver, vehicle, crash, and roadway characteristics. Both fixed- and random-parameters ordered probit models of injury severity (where …

The Atlantic bluefin tuna is a highly migratory species emblematic of the challenges associated with shared fisheries management. In an effort to resolve the species’ stock dynamics, a genomewide search for spatially informative single nucleotide polymorphisms (SNPs) was undertaken, by way of sequencing reduced representation libraries. An allele frequency approach to SNP discovery was used, combining the data of 555 larvae and young‐of‐the‐year (LYOY) into pools representing major geographical areas and mapping against a newly assembled genomic reference. From a set of 184,895 candidate loci, 384 were selected for validation using 167 LYOY. A highly discriminatory genotyping panel of 95 …


Descriptive Density Models Of Scyphozoan Jellyfish In The Northern Gulf Of Mexico, Katrina T. Aleksa, Redwood W. Nero, Jerry D. Wiggert, William M. Graham Mar 2018

Faculty Publications

Jellyfish play an important role in the food web of many coastal environments but are generally considered a nuisance to scientific fieldwork and industrial and economic trades. A better understanding of how jellyfish densities and distributions are affected by environmental parameters could elucidate population trends and provide assistance in ecological research and undesirable human interactions. In this study, abundance data for scyphozoan medusae, Chrysaora sp. and Aurelia spp., were extracted from Southeast Area Monitoring and Assessment Program trawling surveys for the northern Gulf of Mexico (nGoM) during the summer and fall months. Both in situ and satellite oceanographic measurements were …

Maternal undernutrition and mortality remain high in several African countries. Key nutrition andhealth interventions improve maternal and birth outcomes. Evidence is scarce on how tostrengthen health systems to ensure pregnant women and newborns are reached with theseinterventions. We conducted three quasi‐experimental nonrandomized Community BasedMaternal and Neonatal Health and Nutrition projects in regions of Ethiopia, Senegal, and Kenyato demonstrate how proven nutrition interventions could be integrated into health programs toimprove knowledge and practices during pregnancy, birth, and postpartum. We evaluated impacton knowledge and practices related to maternal and neonatal care using logistic regression andrepeated‐measures models with districts as a fixed variable …

Stepping It Up: Walking Behaviors In Children Transitioning From 5th To 7th Grade, Sharon E. Taverno Ross, Morgan N. Clennin, Marsha Dowda, Natalie Colabianchi, Russell R. Pate

Faculty Publications

The purpose of this study was to (1) describe children’s walking behaviors in 5th to 7th grade and change over time and (2) examine associations between walking behaviors and Walk Score®. Participants consisted of n = 586 students from the Transitions and Activity Changes in Kids (TRACK) Study. Children reported any walking behavior (e.g., exercise and transportation) over the past five days. Walk Score was calculated based on children’s home address. Descriptive statistics summarized walking behaviors by gender and time, and repeated measure mixed models examined the relationship between walking behaviors and Walk Score. Approximately 46.8% and 19.2% of 5th …

Understanding the effects of widespread disruption of the social fabric on public health outcomes can provide insight into the forces that drive major political realignment. Our objective was to estimate the association between increases in mortality in middle-aged non-Hispanic white adults from 1999 to 2005 to 2009–2015, health inequalities in life expectancy by income, and the surge in support for the Republican Party in pivotal US counties in the 2016 presidential election. We conducted a longitudinal ecological study in 2764 US counties from 1999 to 2016. Increases in mortality were measured using age-specific (45–54 years of age) all-cause mortality from …
