Affirmative Action Policy Today: Its Effectiveness As Examined In The United States Department Of Commerce, Louritha Green

Political Science Undergraduate Honors Theses

But freedom is not enough. You do not wipe away the scars of centuries by saying: Now you are free to go where you want, do as you desire, choose the leaders you please. you do not take a person who for years has been hobbled by chains and liberate him, bring him up to the starting line of a race and then say, "You are free to compete with all the others," and still justly believe you have been completely fair. (Graham, 182).

These words of President Lyndon Baines Johnson epitomize the foundation on which affirmative action programs were …

Female Reproductive Traits In Selected Arkansas Snakes, Stanley E. Trauth, Robert L. Cox, Walter E. Meshaka Jr., Brian P. Butterfield, Anthony Holt

Journal of the Arkansas Academy of Science

Female reproductive characteristics of 17 genera of Arkansas snakes (27 species and subspecies) were examined. Most of the snakes (n= 495) were collected over a 10-year span (1984-1993). Methods used to estimate clutch and/or litter size were as follows: 1) counts of previtellogenic ovarian follicles,2) counts of vitellogenic ovarian follicles,3) counts of oviductal eggs or embryos, 4) counts of corpora luteal scars, and 5) counts of neonates from egg clutches or litters. In several species, Method 1 tended to overestimate clutch size as determined by Method 2 by as much as 100% (e.g., in Diadophis punctatus, Elaphe obsoleta, and Lampropeltis …

Classification System For The Natural Vegetation Of Arkansas, Thomas L. Foti, Martin Blaney, Xiaojun Li, Kimberly G. Smith

Journal of the Arkansas Academy of Science

We present a hierarchical classification system for existing natural vegetation of Arkansas based on the United Nations Educational, Scientific and Cultural Organization (UNESCO) system. It incorporates aspects of systems in use by the Nature Conservancy, Arkansas Natural Heritage Commission, Arkansas Game and Fish Commission, Society of American Foresters, and United States Forest Service, as well as data on potential vegetation from maps by E.E. Dale and A.W. Kuchler. A total of 18 physiognomic cover types are recognized for natural terrestrial cover, 6 for palustrine cover, and 4 each for lacustrine cover and riverine cover. Over 200 community types are recognized, …

Reproductive Cycles In Two Arkansas Skinks In The Genus Eumeces (Sauria: Scincidae), Stanley E. Trauth

Journal of the Arkansas Academy of Science

Reproductive cycles of the southern coal skink (Eumeces anthracinus pluvialis) and the five-lined skink (E. fasciatus) were studied by examining museum specimens collected in Arkansas. Histological preparations of testes from each species revealed eight spermatogenic stages. Male coal skinks produced sperm by late February, at least one month before male five-lined skinks. Height of the testicular cycle (maximum sperm production-stage 6 = spermiogenesis) in E. a. pluvialis occurred in March and early April, whereas in E. fasciatus, spermiogenesis reached a peak in May. Testicular recrudescence began in late May in E. a. pluvialis and mid-July in E. fasciatus. The reproductive …

Use Of Visual And Tactile Behaviors By Rats (Rattus Norvegicus) In An Object Discrimination Swimming Task, Todd Wiebers

Journal of the Arkansas Academy of Science

When challenged with a cognitive task, rats demonstrate a behavioral flexibility in use and preference of sensory modalities. The present study describes visual and tactile behaviors used by rats in a two choice object discrimination swimming task. The task was designed to preclude use of other sensory modalities and could not be solved via spatial strategies. Fourteen rats learned to criterion a series of 10 discrimination problems. Rats exhibited three stereotypic visual and two stereotypic tactile behaviors over the course of the study. Data analyses indicated that rats demonstrated these behaviors more frequently as they became more familiar with the …
