Omaha Trade Area Study No. 06: License Plate Survey of Five Major Shopping Points

This is the third of a series of continuing studies in the attempt to ascertain Omaha\u27s retail trade area. The method utilized, as in the past, is that of recording license plate prefix numbers at the three major and two minor shopping points within the Omaha SMSA. Emphasis is placed upon the three major shopping points, Downtown, Crossroads and Westroads, for they are the best indicators of the regional focus of Omaha. The two other points surveyed were Southroads and Downtown Council Bluffs (See Map 13, Page 5). This year the survey eliminated The Center, GEM and Skagway because of their community influence

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. 04: Milk, Grain and Livestock Source Area

The milk marketing area of Omaha, shown on Figure 1, includes all or parts of 12 Nebraska counties and 20 counties in western Iowa. Normally 80 percent of Omaha\u27s fluid milk needs comes from the region outlined as Omaha\u27s milk marketing area. Southwest of Omaha, the major milk producing counties of Gage, Jefferson and Lancaster are part of the Lincoln milk marketing area. And to the northwest of Omaha are some of the heaviest bulk-milk producers i.e., milk used for manufactural purposes--dry milk products, etc. Therefore, even though Wayne, Pierce, Antelope and Cedar counties are the major milk producers in Nebraska, they are not included in the Omaha milkshed. Likewise, the major milk producing counties in western Iowa are part of the Sioux City milkshed

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

A continuous model for microtubule dynamics with catastrophe, rescue and nucleation processes

Microtubules are a major component of the cytoskeleton distinguished by highly dynamic behavior both in vitro and in vivo. We propose a general mathematical model that accounts for the growth, catastrophe, rescue and nucleation processes in the polymerization of microtubules from tubulin dimers. Our model is an extension of various mathematical models developed earlier formulated in order to capture and unify the various aspects of tubulin polymerization including the dynamic instability, growth of microtubules to saturation, time-localized periods of nucleation and depolymerization as well as synchronized oscillations exhibited by microtubules under various experimental conditions. Our model, while attempting to use a minimal number of adjustable parameters, covers a broad range of behaviors and has predictive features discussed in the paper. We have analyzed the resultant behaviors of the microtubules changing each of the parameter values at a time and observing the emergence of various dynamical regimes.Comment: 25 pages, 12 figure

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

Changes in salivary estradiol predict changes in women’s preferences for vocal masculinity

Although many studies have reported that women’s preferences for masculine physical characteristics in men change systematically during the menstrual cycle, the hormonal mechanisms underpinning these changes are currently poorly understood. Previous studies investigating the relationships between measured hormone levels and women’s masculinity preferences tested only judgments of men’s facial attractiveness. Results of these studies suggested that preferences for masculine characteristics in men’s faces were related to either women’s estradiol or testosterone levels. To investigate the hormonal correlates of within-woman variation in masculinity preferences further, here we measured 62 women’s salivary estradiol, progesterone, and testosterone levels and their preferences for masculine characteristics in men’s voices in five weekly test sessions. Multilevel modeling of these data showed that changes in salivary estradiol were the best predictor of changes in women’s preferences for vocal masculinity. These results complement other recent research implicating estradiol in women’s mate preferences, attention to courtship signals, sexual motivation, and sexual strategies, and are the first to link women’s voice preferences directly to measured hormone levels
