Differences between values of Australian Aboriginal and non-Aboriginal students

[Abstract]: In this study, the Values Questionnaire developed by Schwartz and Bilsky (1987, 1990) was used to examine differences in the values held by a group of Aboriginal university students (N=112) and a group of non-Aboriginal students (N=106) studying at an Australian university. Results indicated that the Aboriginal group placed greater emphasis on values associated with Tradition, Conformity and Security and significantly less emphasis on values associated with Achievement, Self-direction, Stimulation, Hedonism and Benevolence. These data, in conjunction with a separate analysis of the ten highest ranked values for each group, support the view that the main differences between the groups lie in values serving collective (Aboriginal) as opposed to individual (non-Aboriginal) interests. These findings are consistent with previous research (eg. Christie, 1987) on the world view of traditional Aboriginal people and suggest that even among younger, more 'Westernised', representatives of this culture, collective values are likely to be strong determinants of behaviour

Los Angeles Air Force Base Fitness Center

The purpose of this report is to evaluate the life safety features of the Los Angeles Air Force Base Fitness Center, located on Los Angeles Air Force Base in El Segundo, California. This report is produced in partial fulfillment of the requirements of a Master’s of Science in Fire Protection Engineering from the Fire Protection Engineering Program at California Polytechnic State University’s San Luis Obispo Campus. This analysis approaches life safety in the fitness center from two angles. First, a prescriptive approach is used to evaluate the building’s compliance with current codes and standards that govern construction and maintenance of federal facilities. Four major areas are evaluated prescriptively. Each area is represented by a core code or standard against which the building is measured. Structural fire protection systems are evaluated first. Standards for structural fire protection are codified in the International Building Code and other various standards. Next, life safety is evaluated using NFPA 101 – Life Safety Code as the standard. Third, fire detection and notification systems are evaluated against NFPA 72 – National Fire Alarm and Signaling Code as well as NFPA 70 – National Electric Code. Finally, fire suppression systems are evaluated against the provisions of NFPA 13- Standard for the Installation of Sprinkler Systems. The next portion of this report evaluates the building from a performance-based standpoint using the provisions of Chapter 5 of NFPA 101 – Life Safety Code and supplemented by the SFPE Handbook of Fire Protection Engineering and the NFPA Fire Protection Handbook. This performance-based approach evaluates the building against two fire scenarios designed to challenge all of the buildings fire protection elements. A medium growth sauna fire and an ultra-fast growth polyurethane foam fire are used as scenarios

A NOBLE DREAM: THE INTER-AMERICAN STUDIES PROGRAM AT SOUTHERN ILLINOIS UNIVERSITY, CARBONDALE (1958-1985)

This essay explores the rise and fall of the Inter-American studies program at Southern Illinois University Carbondale. The Inter-American Studies Program attempted to bridge two distinctive bodies of academic literature when Dr. Albert Bork first envisioned it. Unlike other programs founded in the 1950s, SIU’s Inter-American Studies program was an academic experiment challenging that emerging trend. Regardless of its failure, the program’s original idea was innovative

Rarefied gas effects on the aerodynamics of high area-to-mass ratio spacecraft in orbit

The aerodynamic situation of a satellite-on-a-chip operating in low Earth orbit bears some resemblance to a classical Crookes radiometer. The large area-to-mass ratio characteristic of a SpaceChip means that very small surface-dependent forces produce non-negligible accelerations that can significantly alter its orbit. When the temperature of a SpaceChip changes, the drag force can be changed: if the temperature increases, the drag increases (and vice versa). Analytical expressions available in the literature that describe the change in drag coefficient with orbit altitude and SpaceChip temperature compare well with our direct simulation Monte Carlo results presented here. It is demonstrated that modifying the temperature of a SpaceChip could be used for relative orbit control of individual SpaceChips in a swarm, with a maximum change in position per orbit of 50 m being achievable at 600 km altitude
