The management of hazardous and toxic waste projects in Asia (especially that related to intractable chemicals) has had a less than acceptable performance profile during the last 20 years. There have been numerous documented cases of management and systems failures in intractable chemical recovery projects, despite the establishment of global conventions designed to avoid such problems. A research programme was undertaken with the aim of producing a management model for companies to help prevent such failures in the future. The research began in the field with an exploration of management ...

This study analyzes experimental data generated by human subjects using the Perspecta 3D Volumetric Display and a 2D flat screen liquid crystal display (LCD). The analysis reveals differences in how experiment participants used the display technologies.

In 2005, Palla & Baraffe proposed that brown dwarfs and very low mass stars (less than 0.1 solar masses) may be unstable to radial oscillations during the pre-main-sequence deuterium burning phase. With associated oscillation periods of 1-4 hours, this potentially new class of pulsation offers unprecedented opportunities to probe the interiors and evolution of low-mass objects in the 1-15 million year age range. Furthermore, several previous reports of short-period variability have suggested that deuterium-burning pulsation is in fact at work in young clusters. For my dissertation, I develo...

The first generation of children growing up in the 1980s and 1990s with the official diagnosis of ADHD is now completing college and entering the workforce, yet few qualitative research studies examine the experiences of these young adults as they leave the safety of family homes or educational institutions. This study addresses the research question: What are some of the challenging work experiences as described by young adults with ADHD in a structured work environment? Young adults, ages 22- to 28-years-old, from across the USA were interviewed to examine, qualitatively, the types of challe...

Generally, construction of dams is regarded as means of economic progress in many countries. However, major consequences of such projects are the inundation of upstream areas and the resettlement of entire communities in newly built environments where they experience dramatic transformation in their lifestyles. The present study takes the Nubian resettlement experience after the creation of Lake Nasser that submerged their old settlements, along the river Nile. Following their resettlement, the design of the newly-built environment disrupted the Nubian traditional lifestyles and patterns of...

Coalitions of developing countries at the WTO typically have a short life and do not produce results. Nonetheless, a specific coalition of developing countries named the G-20 seems to have a different destiny. Even though it focuses on agriculture, which is certainly the most difficult sector in which one can obtain concessions from developed countries, the G-20 has been able not only to survive but also to solidify its influence. This paper examines the consequences of G-20 actions. Moreover, it considers three separate questions. First, how has the G-20 been able to maintain its unity despit...

As late as 1995, the anticipated widespread population of primeval galaxies remained at large, lurking undetected at unknown redshifts, with undiscovered properties. We present results from our efforts to detect and characterize primeval galaxies by their signature high-redshift Lyman-alpha emission lines utilizing two observational techniques: serendipitous slit spectroscopy and narrowband imaging. By pushing these techniques to their utmost limits, we probe the Lyman-alpha-emitting galaxy population out to redshifts as high as z = 6.5. Galaxies at this epoch reside in a universe which is ...

We study the properties of star-forming galaxies at redshift z~2, an era in which a substantial fraction of the stellar mass in the universe formed. Using 114 near-IR spectra of the H-alpha and [N II] emission lines and model spectral energy distributions fit to rest-frame UV through IR photometry, we examine the galaxies' star formation properties, dynamical masses and velocity dispersions, spatially resolved kinematics, outflow properties, and metallicities as a function of stellar mass and age. While the stellar masses of the galaxies in our sample vary by a factor of ~500, dynami...

Despite the fact the human computer interface is the main facilitator of communication between the user and the computer system, its importance has been highly disregarded by system designers. This has resulted in many undesirable consequences, and in prescription and other healthcare systems, these problems are aggravated by the fact that not only are the users inconvenienced, but there are potential threats to the well-being of the patients under care as well. Many healthcare systems are often designed without considering the potential users of these systems. Consequently, the systems are cr...

This dissertation concerns the structures and individual agency of Filipina brides who met their American husbands through Internet or pen pal advertisements. Popular media, legal scholars, and some feminists have largely described the phenomenon in terms of its oppressiveness toward the women involved, thus dismissing any agency on the part of the women. Similarly, much of the scholarship has located the American Internet grooms as ogres who are out to exploit these women for domestic and sexual services. If prominent researchers of this phenomenon are correct in their assessments that Filipi...
