Geographic Background Report No. 01: Omaha\u27s Agricultural Core Region

One of the critical problems in the delineation of the Omaha Trade Area to be solved by the geographer is the selection of the agricultural hinterland of Omaha. A series of maps, based on the 1959 and 1964 Census of Agriculture reports were developed. These basic maps were correlated with known data concerning agricultural shipments to the Omaha market. The result was the definition of an agricultural core region centered on Omaha

Omaha Trade Area Study No. 01: License Plate Survey of Two Major Shopping Points

This study is a preliminary attempt at the delimitation of Omaha\u27s retail trade area. The method used is that of recording license plate numbers at the two major shopping points in Omaha, the Central Business District and Crossroads, plus two other smaller shopping points--Southroads and The Center. Emphasis is placed upon the two major points for they give the best regional cross-section of Omaha\u27s retail attraction

Omaha Trade Area Study No. 02: An Analysis of Telephone Calls, Newspaper Circulation, and Correspondent Banks

There are many limitations and statistical uncertainties in making a full interpretation of the Omaha Trade Area, but we plan to go as far as we can to bring together the commonly used indicators that show the sphere of influence of a major trade center. A number of indicators, such as retail sales, newspaper circulation, correspondent banks, grain shipments, etc., will be mapped individually. Then, for the final analysis, a composite map will be constructed to show the area of overall dominance by Omaha

Omaha Trade Area Study No. 05: Omaha Spheres of Influence

In nearly all cases, a city represents the focal point of a large area which it dominates. As distance away from the city increases the influence of the city decreases until a point is reached where another city of similar size exerts more influence. The purpose of this study is to establish and discuss the major area of dominance for Omaha

Disrupting the Ethical Imperatives of “Junior” Critical Qualitative Scholars in the Era of Conservative Modernization

In this article, we wrestle with the core issue of how early career researchers translate central tenets and core concepts of critical theory and critical methodology into their research practice. By way of creative representation, we draw from bell hooks and Cornel West’s (1991) written rendition of their verbal dialogue in Breaking Bread: Insurgent Black Intellectual Life. Their hope was to offer the book in a dialogic format in such a way that mirrored the synergy in their verbal discussions as friends and intellectual colleagues. In a similar vein, we hope to share with readers the synergy and depth of the narratives that have transpired during our ongoing discussions on the important topic of critical praxis as part of a collaborative research group called the Disruptive Dialogue Project (Gildersleeve, Kuntz, Pasque & Carducci, 2010; Kuntz, Pasque, Carducci, & Gildersleeve, 2009).Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Menstrual cycle phase does not predict political conservatism

Recent authors have reported a relationship between women's fertility status, as indexed by menstrual cycle phase, and conservatism in moral, social and political values. We conducted a survey to test for the existence of a relationship between menstrual cycle day and conservatism. 2213 women reporting regular menstrual cycles provided data about their political views. Of these women, 2208 provided information about their cycle date, 1260 provided additional evidence of reliability in self-reported cycle date, and of these, 750 also indicated an absence of hormonal disruptors such as recent hormonal contraception use, breastfeeding or pregnancy. Cycle day was used to estimate day-specific fertility rate (probability of conception); political conservatism was measured via direct self-report and via responses to the "Moral Foundations” questionnaire. We also recorded relationship status, which has been reported to interact with menstrual cycle phase in determining political preferences. We found no evidence of a relationship between estimated cyclical fertility changes and conservatism, and no evidence of an interaction between relationship status and cyclical fertility in determining political attitudes. Our findings were robust to multiple inclusion/exclusion criteria and to different methods of estimating fertility and measuring conservatism. In summary, the relationship between cycle-linked reproductive parameters and conservatism may be weaker or less reliable than previously thought

NMDA receptor channels: Labeling of MK-801 with iodine-125 and fluorine-18

Methods for labeling the glutamate channel blocking agent MK-801 with iodine-125 (125I) and fluorine-18 (18F) are described. Radioiodine was incorporated in the 1- or 3-positions of the aromatic ring of (+/-)MK-801 by solid-state halogen exchange techniques. Attachment of the [18F]fluoromethyl group to the bridgehead methyl position was achieved by reaction of [18F]fluoride with the triflamide alcohol 8 or the novel cyclic sulfamate 9 recently reported by Merck chemists. Radiochemical yields of (+/-)13-[18F]- fluoromethyl-MK-801 were >72%, EOB; radiochemical purity >99%. In competitive binding studies using rat brain homogenates, (+/-)3-bromo-MK-801 showed greater affinity than (+/-)MK-801 for the glutamate-linked channel. The experimental log P (2.1 +/- 0.1) of MK-801 is optimal for transit of the blood-brain barrier. These preliminary findings support further testing of 3-[123I]iodo-MK-801 and (+/-)13-[18F]fluoromethyl-MK-801 as possible agents for in vivo mapping of the glutamate receptor complex.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/27605/1/0000649.pd

Synthesis of a nonpeptide carbon-11 labeled substance P antagonist for PET studies

CP 96,345 is a nonpeptide high affinity antagonist of the substance P (NK1) receptor. The radiosynthesis of [11C]CP 96,345 suitable for Positron Emission Tomography (PET) applications is described. [11C]CP 96,345 was prepared by O-methylation of a desmethyl precursor via in situ generation of its phenolate salt. The in vivo tissue distribution of [11C]CP 96,345 in guinea pigs (n = 2) at 5 and 30 min was determined. Uptake was low in brain ([approximate] 0.04% dose/g) and highest ([approximate] 1-2% dose/g) in the spleen and lungs. The present findings indicate that the use of [11C]CP 96,345 in PET might be more applicable to the study of substance P receptors in peripheral tissues involved with inflammatory disease and arthritis.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30822/1/0000482.pd

Facile Preparation of Fluorescent Neoglycoproteins Using p-Nitrophenyl Anthranilate as a Heterobifunctional Linker

A facile preparation of neoglycoconjugates has been developed with a commercially available chemical, p-nitrophenyl anthranilate (PNPA), as a heterobifunctional linker. The two functional groups of PNPA, the aromatic amine and the p-nitrophenyl ester, are fully differentiated to selectively conjugate with glycans and other biomolecules containing nucleophiles. PNPA is efficiently conjugated with free reducing glycans via reductive amination. The glycan−PNPA conjugates (GPNPAs) can be easily purified and quantified by UV absorption. The active p-nitrophenyl ester in the GPNPA conjugates readily reacts with amines under mild conditions, and the resulting conjugates acquire strong fluorescence. This approach was used to prepare several fluorescent neoglycoproteins. The neoglycoproteins were covalently printed on activated glass slides and were bound by appropriate lectins recognizing the glycans
