Expertise And Disbelief: Post-1945 American Attitudes Toward The Authority Of Knowledge, Terry Wagner Jan 2015

Expertise And Disbelief: Post-1945 American Attitudes Toward The Authority Of Knowledge, Terry Wagner

LSU Doctoral Dissertations

“You can’t beat brains,” said President John Kennedy of the intellectuals and technicians he assembled in his cabinet. Kennedy was perhaps the greatest political champion for the virtues of expertise. However, all over America during the 1960s and ‘70s, diverse groups voiced doubts about how much experts, such as social scientists, policy specialists, and others, actually improved life. This dissertation examines how movements on the political left and right, and spiritual ruptures such as the rise of ‘60s counterculture and of evangelicalism, spoke in different language to express a similar point: human mastery over the world is profoundly limited. Many …

The effects of this spill are being studied in labs across the country, and this thesis investigated high-energy water accommodated fractions (HEWAFs) as a potential tool for use in this effort. Water accommodated fractions (WAFs) are mediums containing only the fraction of petroleum that remains in aqueous phase after a mixing …


"The Lonely Romantic": Nature, Education, And Cultural Pessimism In The Early Works Of Hermann Hesse, Erik Paul Wagner Jan 2015

"The Lonely Romantic": Nature, Education, And Cultural Pessimism In The Early Works Of Hermann Hesse, Erik Paul Wagner

LSU Master's Theses

This study examines the early works of Hermann Hesse in the historical context of early twentieth-century Germany. While Hesse’s literary career spans over six decades, most scholarship focuses only on a brief period. Historians study his Weimar novels, as psychologically penetrating pieces that offer insights into this fascinating and chaotic era of German history. Yet, Hesse’s early works have not received due attention in historical scholarship. This situation is unfortunate because Hesse’s prewar writings provide interesting and relevant commentary on life in fin de siècle Germany. Hesse’s early writings offer unique insights into aspects of German culture and society, specifically …

Study Of Factors Affecting Growth And Development Of Narrow Brown Leaf Spot Of Rice Caused By Cercospora Janseana (Racib.) O. Const., Kirandeep Kaur Mani

LSU Doctoral Dissertations

Studies evaluated the effects of planting date, cultivar susceptibility, fungicide application timing, nitrogen management, and tillage practices on the severity of narrow brown leaf spot of rice (NBLS) caused by Cercospora janseana. All factors evaluated affected NBLS severity. The mid-April planted rice had less NBLS as compared to mid-May, late planted rice. Propiconazole fungicide (Tilt) application at panicle initiation or early boot stage was found equally effective in terms of disease reduction in mid-April planting while panicle initiation stage was the best time to apply fungicide in the late planting (mid-May). Early onset and higher severity of NBLS was observed …


Subsampling Reduces Sorting Effort For Waterfowl Foods In Salt-Marsh Core Samples, Mark C. Livolsi, Kevin M. Ringelman, Christopher K. Williams Dec 2014

Subsampling Reduces Sorting Effort For Waterfowl Foods In Salt-Marsh Core Samples, Mark C. Livolsi, Kevin M. Ringelman, Christopher K. Williams

Faculty Publications

Waterfowl researchers often use soil core samples to estimate food availability in foraging habitats, and these estimates are needed for bioenergetic models of carrying capacity. However, core sampling is frequently a time-and resource-intensive process, and some researchers have suggested that subsampling may be a valuable way to reduce processing time. We evaluated whether 10% and 25% by mass subsampling are appropriate techniques for reducing core-sorting effort while maintaining precision for samples taken in six separate habitat types along the Delaware bayshore. We found no significant difference between biomass found in 100% sorted cores and estimated biomass obtained by 10% and …

Responses Of Sympatric Karenia Brevis, Prorocentrum Minimum, And Heterosigma Akashiwo To The Exposure Of Crude Oil, Koray Özhan, Sibel Bargu

Faculty Publications

Impacts of the Deepwater Horizon oil spill on phytoplankton, particularly, the tolerability and changes to the toxin profiles of harmful toxic algal species remain unknown. The degree to which oil-affected sympatric Karenia brevis, Prorocentrum minimum, and Heterosigma akashiwo, all of which are ecologically important species in the Gulf of Mexico, was investigated. Comparison of their tolerability to that of non-toxic species showed that the toxin-production potential of harmful species does not provide a selective advantage. Investigated toxin profiles for K. brevis and P. minimum demonstrated an increase in toxin productivity at the lowest crude oil concentration (0.66 mg L−1 …

Elaborate Visual And Acoustic Signals Evolve Independently In A Large, Phenotypically Diverse Radiation Of Songbirds, Nicholas A. Mason, Allison J. Shultz, Kevin J. Burns Jun 2014

Elaborate Visual And Acoustic Signals Evolve Independently In A Large, Phenotypically Diverse Radiation Of Songbirds, Nicholas A. Mason, Allison J. Shultz, Kevin J. Burns

Faculty Publications

The concept of a macroevolutionary trade-off among sexual signals has a storied history in evolutionary biology. Theory predicts that if multiple sexual signals are costly for males to produce or maintain and females prefer a single, sexually selected trait, then an inverse correlation between sexual signal elaborations is expected among species. However, empirical evidence for what has been termed the 'transfer hypothesis' is mixed, which may reflect different selective pressures among lineages, evolutionary covariates or methodological differences among studies. Here,we examine interspecific correlations between song and plumage elaboration in a phenotypically diverse, widespread radiation of songbirds, the tanagers. The tanagers …

Faculty Publications

Background: Failure of adipocytes to expand during periods of energy excess can result in undesirable metabolic consequences such as ectopic fat accumulation and insulin resistance. Blinded screening studies have indicated that Artemisia scoparia (SCO) extracts can enhance adipocyte differentiation and lipid accumulation in cultured adipocytes. The present study tested the hypothesis that SCO treatment modulates fat cell development and function in vitro and insulin sensitivity in adipose tissue in vivo. Methods: In vitro experiments utilized a Gal4-PPARγ ligand binding domain (LBD) fusion protein-luciferase reporter assay to examine PPARγ activation. To investigate the ability of SCO to modulate adipogenesis and mature …

Tocochromanols are recognized for nutritional content, plant stress response, and seed longevity. Here we present a systems biological approach to characterize and develop predictive assays for genes affecting tocochromanol variation in barley. Major QTL, detected in three regions of a SNP linkage map, affected multiple tocochromanol forms. Candidate genes were identified through barley/rice orthology and sequenced in genotypes with disparate tocochromanol profiles. Gene-specific markers, designed based on observed polymorphism, mapped to the originating QTL, increasing R2 values at the respective loci. Polymorphism within promoter regions corresponded to motifs known to influence gene expression. Quantitative PCR analysis revealed a trend of …

Message from President: With the arrival of summer, colleagues in universities hither and yon will be headed somewhere else for part or all of the recess period. Providing refreshment, permitting research, and perhaps making the heart grow fonder for the home turf, these summertime itinerant intervals have long provided academic personnel with an emotional compensation that occasionally substitutes for the big economic gap in a nine-month salary. Zoroastrians everywhere suspect that good inevitably contrasts with counterpointing evil, and so it is that not every somewhere else is a full of fun, frolic, and fulfilment. Somewhere else might well be declared …
