AIDS, Race, and the Law: The Social Construction of Disease

The existing literature on AIDS and the law has been largely silent on the issue of Acquired Immunodeficiency Syndrome (AIDS) in minority communities, despite the disproportionate impact of AIDS upon these communities, and despite the fact that the literature on behavior change suggests the importance of considering sociocultural and psychological characteristics of a population in the promotion of certain health behaviors and practices

Exploration of Ideal Body Image Among African-American Women

Body image dissatisfaction is a pervasive problem, most notably among women, that is neither well understood nor well defined. Inconsistent and overly narrow definitions of body image make it difficult to draw conclusions regarding the degree and type of dissatisfaction across cultural and/or various ethnic groups. Thus far, research has largely focused on size, shape, and weight concerns, ignoring physical features that may be salient to women belonging to non-Caucasian ethnic groups. This study explored African-American (AA) preferences for weight, waist-to-hip ratio (WHR), and salient physical appearance attributes, as well as their identification with the ¿thin¿ ideal, racial identity salience, and physical racial identity. Participants were 119 AA women and 39 Caucasian women recruited from the St. Louis metropolitan area. Participants¿ actual and ideal physical attributes, current perceived WHR and weight, ideal WHR and weight, and reactions to the WHR and weight assessment task were assessed and examined in relation to ethnic group membership, endorsement of racial identity, identification with the ¿thin¿ ideal, and identification with traditional African physical attributes. Results indicate that AA women reported less discrepancy between their actual-own body image ideal and more ethnic specific features (ESF) as actual traits, but not as ideal traits. There was a negative relationship between internalization of the thin ideal and acceptance of African physical features, but acceptance of African physical features was not related to the number of ESF reported. The salience of race for self-identity was positively related to the number of ESF reported as representative of the cultural ideal only. Although a significant interaction between physical racial identity and internalization of the thin ideal was found, further analyses did not support the hypothesized moderation effect. Finally, AA participants reported less of a discrepancy between their perceived current and ideal weight, but not WHR, and reported more concerns with the WHR/FRS measure than the Caucasian participants. The present study lends support to the differences in salient physical characteristics across ethnic groups. Strategies to increase understanding and completion of the measures, further examine relationships among racial identification and body image measures, and improve reliability of findings are discussed

The Velocity and Shape of Gas Slugs Rising in Vertical Tubes and Rectangular Slots.

The rise of a large gas bubble, or slug, through a closed, vertical, liquid-filled channel of infinite length has been investigated by means of potential flow theory. Three channel geometries are considered: (1) the circular tube, (2) the two-dimensional rectangular channel and (3) the three-dimensional rectangular slot. The effect of inter- facial surface tension is explicitly accounted for by application of the Kelvin-LaPlace equation, thus making the bubble shape an integral part of the solution. For the circular tube of radius R and diameter D, the solution is expressed in terms of the Stokes Stream Function which consists of an infinite Bessel Function series. The resultant equations have been solved numerically for the first six terms in the series. For negligible surface tension and ideal liquid, the bubble rise velocity is given by U(,s) = 0.352 SQRT.(gD) and the radius of curvature at the bubble nose R(,c) = 0.75R. For air/water and D = 2.54 cm, the inclusion of surface tension gives U(,s) = 0.346 SQRT.(gD) and R(,c)/R = 0.71. It is also shown for the tube case that the potential flow solution may be applied with good results to liquids of moderate viscosity if an effective tube radius R(,eff) (TBOND) R - (nu)(delta) is used, where (nu) is a function of the liquid properties and (delta) is the laminar wall film thickness. For rectanguar channels, the solution is expressed in terms of the velocity potential function which consists of an infinite series of trigonometric functions. In the case of a two-dimensional rectangular channel, of finite length 2L and infinite width, the solution does not converge as rapidly as for the tube case. For a three-dimensional rectangular slot of length 2L and width 2W, the solution converges even more slowly than the two-dimensional channel case, especially at large aspect ratios and significant surface tension. For negligible surface tension, the theoretical solution compares well with measured data for aspect ratios up to 6. For a square channel and negligible surface tension, a value of Fr = 0.333 is calculated compared to the measured value of 0.330. Including surface tension in the three-dimensional solution decreases the maximum aspect ratio at which the solution gives good agreement with data, for the same number of terms in the series expansion. For a 7.62 cm square channel and an air/water system, a value of Fr = 0.330 is calculated compared to the measured value of 0.330. (Abstract shortened with permission of author.)

Coloration of glass by high energy radiation

Purpose of Investigation: One of the objects of this investigation is to determine the amount of CeO2 required to prevent the discoloration of glass when exposed to gamma radiation. By discoloration, it is meant that there has been a change in the absorption bands of visible light. Another objective is an attempt to prevent the coloration by the introduction of two oxides not previously used. Finally, a theory is presented which could explain why glass containing CeO2 does not change color upon irradiation by gamma rays --Introduction, page 1

National Register of Historic Places multiple property documentation form -- Historic, archaeological, and traditional cultural properties of the Hanford Site, Washington

The US Department of Energy`s Hanford Site encompasses an area of 560 square miles on the Columbia River in southeastern Washington. Since 1943, the Hanford Site has existed as a protected area for activities primarily related to the production of radioactive materials for national defense uses. For cultural resources on the Hanford Site, establishment of the nuclear reservation as a high security area, with public access restricted, has resulted in a well-protected status, although no deliberate resource protection measures were in effect to mitigate effects of facilities construction and associated activities. Thus, the Hanford Site contains an extensive record of aboriginal archaeological sites and Native American cultural properties, along with pre-Hanford Euro-American sites (primarily archaeological in nature with the removal of most pre-1943 structures), and a considerable number of Manhattan Project/Cold War era buildings and structures. The recent mission change from production to clean up and disposal of DOE lands created a critical need for development and implementation of new and different cultural resource management strategies. DOE-RL has undertaken a preservation planning effort for the Hanford Site. The intent of this Plan is to enable DOE-RL to organize data and develop goals, objectives, and priorities for the identification, evaluation, registration, protection, preservation, and enhancement of the Site`s historical and cultural properties. Decisions made about the identification, evaluation, registration and treatment of historic properties are most aptly made when relationships between individual properties and other similar properties are considered. The historic context and the multiple property documentation (NTD) process provides DOE-RL the organizational framework for these decisions. Once significant patterns are identified, contexts developed, and expected properties are defined, the NTD process provides the foundation for future decisions concerning the management of significant cultural resources on the Hanford Site
