From Jobs to Power: The United Construction Workers Association and Title VII Community Organizing in the 1970s
A history of the first two years of the United Construction Workers Association (UCWA) in Seattle, Washington, and its struggle to represent black workers entering the construction industry under court order separately from organized labor and employers
"The Blacks Should Not Be Administering the Philadelphia Plan": Nixon, the Hard Hats, and âVoluntaryâ Affirmative Action
History of the "racial reconciliation" staged by building trades unions and President Richard Nixon, through which building trades union leaders taught Nixon how to reach out to organized labor and the white working class for the 1972 election in exchange for the President withdrawing his support for affirmative action in the construction industry
The influence of date of birth and calving season on preweaning growth rate, type score, condition score, and weanling index of beef calves
The purpose of this study was to determine the influence of season of birth (numerical day in year calved) upon preweaning gain, weaning type score, condition score and index
Experimental Investigation of Reinforced Concrete Beams with Lapped Reinforcement
One of the great contributions made by President Dwight D. Eisenhower was his influence in the implementation of the National Interstate and Defense Highways Act of 1956. The National Highway System serves an important role in American citizen\u27s ground transportation. Now more than a half of a century in age, there is a high priority to repair existing infrastructure as well as the need for expansion. Repair and expansion must be achieved efficiently by reducing construction time and improving the capacity and durability of the structure. Precast, prestressed decked bulb tees (DBTs) serve as an excellent solution to ensure quality from an on-site precast concrete fabricator and also to reduce construction time. This thesis focuses on the research involved in the interface connections of these DBTs. Eight specimens of reinforced concrete with two connection details at the center span of the beam were tested, and the results serve as a conservative estimate to the behavior of the jointed interface. Two different prospective joint designs were tested in this project. One type was a headed bar reinforcement which was tested in various spacing and lap lengths. The second type of joint was welded wire reinforcement with varying wire spacing. In order to accelerate bridge construction, it is desirable to narrow the width of the jointed zone. However, the width has to be wide enough to accommodate non-contact lapped reinforcement as well as to develop strength in the joint. According to the moment versus steel stress comparison from the strain gauge results, the 6 inch lap length specimens with headed bars behaved as a continuous reinforced specimen. Moment curvature suggests that the 6 inch lap length provides the design moment capacity and ductility. With the same 6 inch lap length, it was found that the specimen with 4 inch spacing of reinforcement provided 1.5 times the moment capacity of the 6 inch spacing of reinforcement without significantly compromising ductility
Increasing the Social Connection Between Immigrant English Language Learners, School Staff, and Peers in the High School Setting
An Immigrant English Language Learner (ELL) encounters many new and different experiences when they enter high school. This transition can lead to a sense of loneliness and isolation if the student is not comfortable. However, if ELLs feel welcomed, valued, and connected to others, the high school experience can be a positive one. This research project was designed to use a personal presentation learning tool as a way to establish a needed social connection between ELLs, school staff, and native speaking peers as a way to enhance personal relationships, promote cultural understanding, and connect students to their new setting
Human and Non-Human Primate Preferences for Faces and Facial Attractiveness
For humans and non-human primates (NHPs) the face represents a particularly important source of social information providing a means of conspecific recognition and cues to personal details including sex, age, and emotional state. The human face may also be fundamental in the transmission to conspecifics of other forms of socially relevant information including the display of facial traits associated with sexual attraction and mate choice. A wealth of experimental literature indicates that humans display robust preferences for certain facial traits associated with facial attractiveness including preferences for bilateral facial symmetry, facial averageness and sexually dimorphic faces and facial features. It is thought that these preferences have evolved via sexual selection, and may be adaptive, due to the role that these specific facial features play in reliably signalling to others the possession of heritable genetic quality or âgood genesâ.
Therefore, from an evolutionary perspective, it is possible that certain facial preferences may represent an evolutionary adaptation for the selection of potential mate quality. However, despite similarities between human and NHP face processing and recognition abilities, the shared evolutionary history and social importance of faces to primates in general, and the potential importance of these preferences in the mate choice decisions of NHPs, very little research has investigated the extent to which NHPs display comparable preferences to humans for these specific facial traits.
Consequently, the aim of the following thesis was to comparatively assess the general and more specific preferences that humans and NHPs display for faces and for traits associated with facial attractiveness. Data was compiled from preference studies examining the visual preferences displayed by two species of NHP (brown capuchins (Cebus apella) and chimpanzees (Pan troglodytes)) for conspecific faces manipulated for those facial traits associated with attractiveness, and from a single study of brown capuchins examining their general visual preferences for various types of facial information. Comparative preference studies were also conducted upon human adults and infants examining the visual and declared preferences that they display for manipulations of facial attractiveness.
Data showed that despite possessing general preferences for certain faces and facial information, generally NHPs displayed no significant preferences for those facial traits thought to influences judgements of attractiveness in humans. Possible reasons for this absence of preference for these particular facial traits and the evolutionary implications of these findings are discussed
