Cognitive Theory and the Selling of the Flat Tax
No full textIn this article, Professor Deborah A. Geier brings to bear the insights of Professor Edward J. McCaffery, regarding the interaction of cognitive theory and the tax world, to the flat tax proposal. The article explores how the perceptual biases described by Professor McCaffery might affect both taxpayers\u27 impressions of the contours of the proposed tax base and their behavioral reponses to the same incentive. The author warns that any errors in her application of Professor McCaffery\u27s work to the flat tax are entirely her own
Fels - Geier - Eltern : Untersuchungen zum Gottesbild des Moseliedes (Dtn 32)
No full textDas Moselied gilt wegen seiner kompositorisch zentralen Position am Ende des Pentateuch und seiner poetischen Form als theologischer Spitzentext. Die Autorin fragt nach der Konstruktion des Gottesbildes durch die drei zentralen Metaphern Fels, Geier und Eltern. Nach einer Analyse der Gesamtstruktur des Liedes untersucht sie die Metaphern in zwei Schritten. Dabei bildet die Einordnung der Metaphern in den literarischen Kontext der Hebräischen Bibel den Hintergrund der semantischen und intertextuellen Untersuchung der Metaphern im Moselied. Die Studie ermöglicht damit - jenseits der verbreiteten Dichotomie von »positiven« und »negativen « Gottesbildern - einen differenzierteren Blick auf die Spannungen und Komplexitäten des alttestamentlichen Gottesbildes.Due to its compositionally central position at the end of the Pentateuch and its poetical form, the Song of Moses is counted among the seminal theological texts of the Old Testament. The author explores the construction of the image of God by analysing the three central metaphors of the rock, vulture, and parents. A synchronic and diachronic analysis of the overall structure is followed by an analysis of the metaphors in the light of the history of motives, which places it in the literary context of the Hebrew Bible, as well as opening up the perspective of deutercanonical and Qumran literature, and taking into account iconographic and textual sources from the Ancient Near East. The purpose is to offer a differentiated consideration of the tensions and complexities of the Old Testament image of God beyond the dichotomy of "positive" and "negative"
The Application of Farm Programs to Commercial Fisheries: The Case of Crop Insurance for the Bristol Bay Commercial Salmon Fisheries
No full textUnder the direction of the Agricultural Risk Protection Act of 2000, the U.S. Congress proposed a crop insurance program for the Bristol Bay, Alaska, commercial salmon fishery. This study examines the feasibility of extending crop insurance to this commercial fishery. The specific focus of this analysis is on differences between this commercial capture fishery and agricultural enterprises in the context of property rights and producer control. Findings show that differences between this commercial fishery and agricultural enterprises would require substantial modifications to existing crop insurance programs. Furthermore, it is recommended that the consideration of extending crop insurance be delayed until this fishery is rationalized.Bristol Bay, commercial fisheries, crop insurance, farm programs, property rights, risk management, salmon, Agricultural and Food Policy, Risk and Uncertainty,

Metabolic and molecular responses to interspecies hydrogen transfer between Ruminococcus albus and Wolinella succinogenes
No full textThe mutually beneficial interdependence of hydrogen-producing and hydrogen-utilizing bacteria was discovered by M. P. Bryant, M. J. Wolin and R. S. Wolfe at the University of Illinois in 1967. Based on thermodynamic principles, interspecies hydrogen transfer is a central process in anaerobic environments linking transfer of reducing power from fermentation of organic molecules to inorganic electron acceptors via hydrogen. Interspecies hydrogen transfer is the most significant example of unidirectional substrate supply enabling the syntrophic metabolic association between interacting microbial species and plays a significant role in the global methane cycle. Ruminococcus albus 7 is a hydrogen-producing, fermentative bacterium with two known hydrogen-producing hydrogenase complexes, HydABC and HydA2, as well as a putative hydrogen-sensing protein, HydS. HydABC is the only chromosomal hydrogenase, while HydA2 and HydS form a transcriptional unit on its plasmid pRumal01. The electron-bifurcating ferredoxin- and NAD-dependent [FeFe]-hydrogenase, HydABC, couples proton reduction using nicotinamide adenine dinucleotide (NADH) to proton reduction using reduced ferredoxin (Fdred), producing molecular hydrogen: 3 H+ + NADH + Fdred → 2 H2 + NAD+ + Fdox. HydA2, a ferredoxin-dependent [FeFe]-hydrogenase, reduces protons to molecular hydrogen using only reduced ferredoxin: 2 H+ + Fdred → H2 + Fdox. HydS contains a PAS domain, which often are present on sensory proteins. In addition, HydS contains a putative redox-sensing [4Fe:4S] cluster.
We hypothesized HydS transcriptionally regulates HydA2 in a manner dependent on the presence of a hydrogen-utilizing syntroph. To test this hypothesis, R. albus 7 and a hydrogen-utilizing bacterium, Wolinella succinogenes DSM 1740, were grown in pure culture and in co-culture. W. succinogenes uses hydrogen as an electron acceptor for fumarate respiration. Cell growth was monitored by optical density (OD600) and quantitative polymerase chain reaction (qPCR). Metabolites were measured to observe changes caused by the interaction of the two bacteria. Lastly, RNA was extracted at mid-log phase for sequencing to compare whole genome transcriptomic profiles. Hydrogen accumulated in the R. albus pure culture, but not in the co-culture. Production of acetate increased and ethanol decreased when R. albus was grown in co-culture with W. succinogenes. Transcript abundance of HydA2 was 90-fold lower in co-culture, relative to pure culture. The electron-bifurcating hydrogenase, HydABC, had a small change in transcript abundance in co-culture relative to pure culture (1.2- to 1.3-fold increase). This suggests HydS might be sensing hydrogen levels and regulating the transcription of HydA2. These results also suggest the electron-bifurcating hydrogenase (HydABC) functions in central metabolism regardless of external hydrogen concentration. In addition, many genes in central carbon metabolism, de novo thiamin biosynthesis, and methionine transport were significantly increased.
W. succinogenes reduced all the fumarate to succinate in both the pure culture and the co-culture with R. albus. Two of the three subunits of the [NiFe]-hydrogenase in W. succinogenes had an increase in transcript abundance of 2.7-fold to 2.9-fold. The transcripts for fumarate reductase had a small increase in abundance in co-culture (1.2-fold). W. succinogenes had an increased growth rate in co-culture. Other respiratory genes in W. succinogenes had increased transcriptional abundance, including formate dehydrogenase and genes involved in nitrate reduction. Transcripts for fumarate respiration were much higher than for nitrate respiration. This is the first study to show at the genome and metabolite levels that R. albus and W. succinogenes benefit from symbiotic IHT, although formate transfer may have been occurring in co-culture as well.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-08-01The student, Renae Geier, accepted the attached license on 2016-07-18 at 12:35.The student, Renae Geier, submitted this Thesis for approval on 2016-07-18 at 12:44.This Thesis was approved for publication on 2016-07-19 at 15:31.DSpace SAF Submission Ingestion Package generated from Vireo submission #9987 on 2016-11-10 at 12:20:54Made available in DSpace on 2016-11-10T18:27:55Z (GMT).

Incentive Processing and Inhibitory Control in Adolescents and Young Adults
No full textAdolescents are known to demonstrate normative increases in risk-taking behaviors. Understanding the interaction between incentive (reward, punishment) processing and basic cognitive control abilities, both of which are still maturing into adolescence, may provide insight on the basic mechanisms contributing to this complex behavioral phenomenon. In this dissertation, we present a compilation of papers aimed at characterizing the influence of potential reward gain or loss on response inhibition performance and supporting brain circuitry in adolescents and adults. In study 1, we use fast, event-related functional magnetic resonance imaging (fMRI) to examine the neural circuitry supporting perfomance on an antisaccade task with reward or neutral contingencies added to each trial. Results indicate that components of the adolescent reward system exhibit an initially sluggish, then eventually overactive response to rewards, as well as limited recruitment in regions supporting the executive assessment of rewards. In study 2, the effects of different magnitudes of potential gains and losses on antisaccade task performance were examined. Results indicate that higher compared to lower magnitude reward contingencies differentially affect adolescent, but not adult, response suppression abilities. Furthemore, both age groups performed consistently well (low error rates) on punishment trials. In study 3, adolescents and adults underwent fast, event-related fMRI as they performed a rewarded antisaccade task with fixed-magnitude reward and punishment stimuli, previously determined to result in equivalent levels of behavioral performance across the age groups (study 2). Additionally, auditory, performance-based feedback was provided on each trial. fMRI results indicate that during detection of reward cues, adolescents do not show the same early recruitment of oculomotor control regions evident in adults. Furthermore, adolescents demonstrated temporally extended responses in several brain regions (e.g., orbitofrontal cortex, supplementary eye field) during the preparatory period of potential punishment trials, reflecting possible immaturities in mechanisms underlying potential loss or 'risk' anticipation. Finally, adults demonstrated enhanced activity in the ventral striatum and cortical eye fields during the response/feedback epoch, suggesting more mature consummatory processing. Collectively, the results of these studies demonstrate protracted development of higher-order executive aspects of reward processing and its interaction with response inhibition abilites into adolescence
Classification of agricultural systems based on pesticide use intensity and safety
No full textAn analysis of socio-economic driving forces in crop protection is proposed to improve the implementation of sustainable strategies. The analysis includes: (1) a classification of agricultural systems based on pesticide use intensity and safety, (2) an evaluation of the profitability of farming systems and identification of socio-economic factors that influence pesticide use and (3) formulation of policy recommendations. We find that for cereals and for fruit trees alike, crop yields are much higher for agricultural systems with high doses of pesticides. The safety of applied pesticides does not affect crop protection costs significantly. For cropping systems characterised by low-intensity in pesticide use, the application of safer products has a positive effect on reduction of crop protection costs.pesticide use, driving forces in crop protection, economic analysis of agricultural systems, Crop Production/Industries,
