Faculty Publications

The Avon Longitudinal Study of Parents and Children (ALSPAC) is an observational study of 14273 UK pregnant singleton mothers in 1990/1991. We examined outcomes of self report of strenuous activity (hours per week) at 18 and 32 weeks of gestation, hours spent in leisure-time physical activities and types, and pre-pregnancy body mass index (BMI); overweight status was defined as pre-pregnancy BMI$25 and obesity BMI$30. Pet ownership and activity data were reported for 11,466 mothers. Twenty-five percent of mothers owned at least one dog. There was a positive relationship between participation in activity at least once a week and dog ownership …

Epithelial Na + Sodium Channels In Magnocellular Cells Of The Rat Supraoptic And Paraventricular Nuclei, Ryoichi Teruyama, Mayumi Sakuraba, Lori L. Wilson, Narine E.J. Wandrey, William E. Armstrong

Faculty Publications

The epithelial Na + channels (ENaCs) are present in kidney and contribute to Na + and water homeostasis. All three ENaC subunits (α, β, and γ) were demonstrated in the cardiovascular regulatory centers of the rat brain, including the magnocellular neurons (MNCs) in the supraoptic nucleus (SON) and the paraventricular nucleus (PVN). However, the functional significance of ENaCs in vasopressin (VP) and oxytocin (OT) synthesizing MNCs is completely unknown. In this study, we show with immunocytochemical double-labeling that the α-ENaC is colocalized with either VP or OT in MNCs in the SON and PVN. In addition, parvocellular neurons in the …

Reproductive Efficiency Of Captive Chinese- And Indian-Origin Rhesus Macaque (Macaca Mulatta) Females, H. Michael Kubisch, Kathrine P. Falkenstein, Chelsea B. Deroche, Donald E. Franke

Faculty Publications

Reproductive and survival records (n = 2,913) from 313 Chinese-origin and 365 Indian-derived rhesus macaques at the Tulane National Primate Research Center (TNPRC) spanning three generations were studied. Least-squares analysis of variance procedures were used to compare reproductive and infant survival traits while proportional hazards regression procedures were used to study female age at death, number of infants born per female, and time from last birth to death. Chinese females were older at first parturition than Indian females because they were older when placed with males, but the two subspecies had similar first postpartum birth interval (1st PPBI) and lifetime …

Predicting Patch Occupancy In Fragmented Landscapes At The Rangewide Scale For An Endangered Species: An Example Of An American Warbler, Bret A. Collier, Julie E. Groce, Michael L. Morrison, John C. Newnam, Andrew J. Campomizzi, Shannon L. Farrell, Heather A. Mathewson, Robert T. Snelgrove, Raymond J. Carroll, Robert N. Wilkins

Faculty Publications

Aim Our objective was to identify the distribution of the endangered golden-cheeked warbler (Setophaga chrysoparia) in fragmented oak-juniper woodlands by applying a geoadditive semiparametric occupancy model to better assist decision-makers in identifying suitable habitat across the species breeding range on which conservation or mitigation activities can be focused and thus prioritize management and conservation planning. Location Texas, USA. Methods We used repeated double-observer detection/non-detection surveys of randomly selected (n=287) patches of potential habitat to evaluate warbler patch-scale presence across the species breeding range. We used a geoadditive semiparametric occupancy model with remotely sensed habitat metrics (patch size and landscape composition) …

Ecological Guild Evolution And The Discovery Of The World's Smallest Vertebrate, Eric N. Rittmeyer, Allen Allison, Michael C. Gründler, Derrick K. Thompson, Christopher C. Austin

Faculty Publications

Living vertebrates vary drastically in body size, yet few taxa reach the extremely minute size of some frogs and teleost fish. Here we describe two new species of diminutive terrestrial frogs from the megadiverse hotspot island of New Guinea, one of which represents the smallest known vertebrate species, attaining an average body size of only 7.7 mm. Both new species are members of the recently described genus Paedophryne, the four species of which are all among the ten smallest known frog species, making Paedophryne the most diminutive genus of anurans. This discovery highlights intriguing ecological similarities among the numerous independent …

Improved Self-Control Associated With Using Relatively Large Amounts Of Glucose: Learning Self-Control Is Metabolically Expensive, Matthew T. Gailliot

Faculty Publications

The current study examined whether changes in glucose during a self-control task would predict changes in self-control performance later on. Participants attended two experimental sessions, spaced two weeks apart. During each session, they had their glucose measured, completed the Stroop task as a measure of self-control, and then had their glucose measured again. Larger decreases in glucose (from before to after the Stroop task) during the first session predicted larger increases in improvement on the Stroop task during the second session, in the form of increased speed. Learning self-control might benefit from using larger amounts of glucose. Learning self-control is …

Mortality Salience And Metabolism: Glucose Drinks Reduce Worldview Defense Caused By Mortality Salience, Matthew T. Gailliot

Faculty Publications

The current work tested the hypothesis that a glucose drink would reduce worldview defense following mortality salience. Participants consumed either a glucose drink or placebo, wrote about either death or dental pain, and then completed a measure of worldview defense (viewing positively someone with pro-US views and viewing negatively someone with anti-US views). Mortality salience increased world- view defense among participants who consumed a placebo but not among participants who consumed a glucose drink. Glucose might reduce defensiveness after mortality salience by increasing the effectiveness of the self-controlled suppression of death-related thought, by providing resources to cope with mortality salience …

Breaking The Rules: Low Trait Or State Self-Control Increases Social Norm Violations, Matthew T. Gailliot, Seth A. Gitter, Michael D. Baker, Roy F. Baumeister

Faculty Publications

Two pilot and six studies indicated that poor self-control causes people to violate social norms and rules that are effortful to follow. Lower trait self-control was associated with a greater willingness to take ethical risks and use curse words. Participants who completed an initial self-control task that reduced the capacity for self-control used more curse words and were more willing to take ethical risks than participants who completed a neutral task. Poor self-control was also associated with violating explicit rules given by the experimenter. Depleting self-control resources in a self-control exercise caused participants subsequently to talk when they had been …

Marked Woman (1937) And The Dialectics Of Art Deco In The Classical Gangster Genre, Drew Todd

Faculty Publications

In this article, I analyse the function of Art Deco designs in the 1930s gangster genre and, in particular, Warner Brothers' Marked Woman (Bacon, 1937). Like many gangster films of the period, it associates high-style Art Deco with excess and the criminal underworld. My findings, however, reveal a tension between the film's moralist stance and its visual excess. Compelling visual signifiers of leisure, style and social mobility, the modern designs are free to circumvent the film's critical message and reinforce American capitalist ideologies. My analyses underscore Art Deco as an emblematic style of commercial modernity. Marked Woman and other gangster …

The Effects Of Distractors In Multiple Object Tracking Are Modulated By The Similarity Of Distractor And Target Features, Cary S. Feria

Faculty Publications

Is the effect of distractors in multiple object tracking dependent on the distractors sharing the features of the targets? In experiment 1, observers tracked five targets among five distractors that were identical to the targets and a number of additional distractors that were either identical to or featurally distinct from the targets. Results showed that distractors that are distinct from the targets in shape or color, or are stationary, impair tracking less than distractors that are identical to the targets. However, tracking performance declined as the number of distractors increased, even for featurally distinct distractors. Experiment 2 showed that distractors …

Effects Of An Invasive Plant, Chinese Tallow (Triadica Sebifera), On Development And Survival Of Anuran Larvae, Taylor B. Cotten, Matthew Kwiatkowski, Daniel Saenz, Michael Collyer

Faculty Publications

Amphibians are considered one of the most threatened vertebrate groups. Although numerous studies have addressed the many causes of amphibian population decline, little is known about effects of invasive plants. Chinese tallow (Triadica sebifera) is an exotic deciduous tree that has invaded the southeastern United States. Amphibian larvae in environments invaded by T. sebifera may be impacted negatively as autumn leaf litter decomposes in natal areas. We compared effects of leaf litter decomposition from T. sebifera and two native tree species on survival and development of four species of anuran larvae from eastern Texas. Larvae from Pseudacris fouquettei, Lithobates (Rana) …

Nest Success And Hatchling Survival Of American Alligators Within Inland Wetlands Of East Texas, Warren C. Conway, Gary Calkins, David Saalfeld

Faculty Publications

Because of liberalization of American alligator (Alligator mississippiensis) harvest management in Texas, estimates of nest success and hatchling survival for inland populations are essential for long-term, sustainable population and harvest management. To date, few studies have examined American alligator nest success and hatchling survival. We initiated a 3-year study from 2006 to 2008 to document alligator nest success and hatchling survival within several wetlands in east Texas. From June 2006 to August 2008, we located 30 nests from 3 wetlands within east Texas, where overall nest success was 44.2% (95% CI=25.1– 63.1%), irrespective of year. Nest circumference and day during …

Snowy Plover Nest Site Selection, Spatial Patterning, And Temperatures In The Southern High Plains Of Texas, David Saalfeld, Warren C. Conway, William P. Johnson, David A. Haukos

Faculty Publications

Snowy plover (Charadrius nivosus) populations have declined throughout their range, in part because of habitat degradation and poor nest success, making information regarding regionally specific nest site selection and spatial patterns important when considering habitat conservation and management guidelines. We determined nest site selection characteristics (n=80) and examined spatial patterns (n=215) of snowy plover nests in saline lakes in the Southern High Plains (SHP) of Texas. At 104 nests, we examined the influence of substrate type on nest temperatures and heat mitigation. Snowy plover nests were more likely to be found near an object, on pebble substrate, and with fewer …

Relationally Aggressive Media Exposure And Children’S Normative Beliefs: Does Parental Mediation Matter?, Jennifer Ruh Linder, Nicole E. Werner

Faculty Publications

Research indicates that relationally aggressive media exposure is positively associated with relational aggression in children. Theories of media effects suggest that these associations may be mediated by aggressive cognitions. Although parental mediation can attenuate the effects of violent media, it is unknown whether there are similar benefits of parental mediation of relationally aggressive media. The current study examined concurrent and longitudinal associations between relationally aggressive television and movie exposure and normative beliefs about relational aggression, and whether parental mediation moderates these associations. Participants were 103 children (50% female) in grades 3-6 and their parents. The following year, 48 children (52% …

A Systematic Genetic Screen To Dissect The Microrna Pathway In Drosophila, Sigal Pressman, Catherine A. Reinke, Xiaohong Wang, Richard W. Carthew

Faculty Publications

A central goal of microRNA biology is to elucidate the genetic program of miRNA function and regulation. However, relatively few of the effectors that execute miRNA repression have been identified. Because such genes may function in many developmental processes, mutations in them are expected to be pleiotropic and thus are discarded in most standard genetic screens. Here, we describe a systematic screen designed to identify all Drosophila genes in ~40% of the genome that function in the miRNA pathway. To identify potentially pleiotropic genes, the screen analyzed clones of homozygous mutant cells in heterozygous animals. We identified 45 mutations representing …

Solving The Good-Time Puzzle: Why Following The Rules Should Get You Out Of Prison Early, Michael M. O'Hear

Faculty Publications

Good-time programs have long been an important part of the American penal landscape. At least twenty-nine states and the federal government currently offer prison inmates early release, sometimes by many years, in return for good behavior.

Written a generation ago, the leading scholarly article on the subject presented a strong case against good time, which has yet to be effectively addressed. Although good time is traditionally justified by reference to its usefulness in deterring inmate misconduct — credits can be denied or withdrawn as a penalty for violations of prison rules — the article questioned how it could possibly be …

The Drugs Stop Here: A Public Health Framework To Address The Drug Shortage Crisis, Sharona Hoffman

Faculty Publications

Drug shortages are emerging as a major public health threat. Grave concern has been expressed by the medical community and government officials, and the crisis has been highlighted in recent media stories. Nevertheless, little has been written to date in the legal literature about the drug shortage crisis, and this timely article begins to fill this gap. It provides a thorough analysis of the origins and implications of the drug shortage problem and formulates a multi-layered approach to addressing it. The article argues that drug shortages result from a combination of market failures and regulatory constraints. It proposes a blend …

Medical Decision Making By And On Behalf Of Adolescents: Reconsidering First Principles, B. Jessie Hill

Faculty Publications

The school nurse cannot give your teenage daughter an aspirin for her headache without your permission, but that same daughter can get an abortion without even informing you. Or can she? The obligations on medical personnel providing care to adolescents are famously indeterminate.

Two common-law presumptions have long lurked in the background, but, far from elucidating matters, those presumptions have contributed to the state of confusion. The first presumption is that, absent any special rule, children lack the legal authority to consent to medical treatment on their own. A parallel and corresponding presumption is that parents have a legal entitlement …

Retrotransposons As A Major Source Of Epigenetic Variations In The Mammalian Genome, Muhammad B. Ekram, Keunsoo Kang, Hana Kim, Joomyeong Kim

Faculty Publications

Transcription of retrotransposons is usually repressed by DNA methylation, but a few elements, such as intracisternal A-particles (IAPs) associated with the Agouti and Axin-fused loci, partially escape this repression mechanism. The levels of this repression are also variable among individuals with an identical genome sequence, generating epigenetically different states of loci or epialleles. In the current study, we tested the existence of additional retrotransposon-derived epialleles in the mouse genome. Using a series of bioinformatics approaches, 143 candidate epialleles were first identified from the mouse genome based on their promoter activity and association with active histone modification marks. Detailed analyses suggest …
