Comprehensive global garbage detection (GGD) in object-oriented distributed systems, i.e., GGD intrinsically able to detect distributed cycles of garbage, has mostly been addressed via graph tracing algorithms. Graph tracing algorithms must account for every live object in the system before any resource can actually be reclaimed which compromises both their scalability and robustness in a distributed environment. Alternative non-comprehensive approaches trade-off comprehensiveness for scalability and robustness under the assumptions that distributed cycles of garbage are rare and that al...

An empirical study was undertaken (a) to examine the characteristics, influencing factors, and effectiveness of a distinctive Chinese management model adopted by the newly founded private enterprises in mainland China, as well as (b) to test the "fit" notion in contingency theory. The study was based on a random sample of 124 standardized personal interviews with CEOs of Chinese industrial and service companies in Beijing and Shanghai. The standardized questionnaire mainly contained the Aston structure scales (Pugh and Hickson 1976) and Khandwalla's (1977) management schedules. Besides, three ...

In this dissertation, a new spare capacity planning methodology is proposed utilizing path restoration. The approach is based on forcing working flows/traffic which are on paths that are disjoint to share spare backup capacity. The algorithm for determining the spare capacity assignment is based on genetic algorithms and is capable of incorporating non-linear variables such as non-linear cost function and QoS variables into the objective and constraints. The proposed methodology applies to a wider range of fault scenarios than most of the current literature. It can tolerate link-failures, n...

Recent changes in the New South Wales water utilities show a trend towards usage-related pricing, with the aim of providing efficient signals for consumption. This thesis evaluates alternative pricing strategies for water against the criteria of efficiency and equity while maintaining the financial viability of the public utility. First, the water utility cost structure is examined by developing cost functions to estimate short and long-run marginal costs, using a quarterly time-series data from 1970/71 to 1995/96. Second, a residential water demand model is developed using a panel data set...

This study uses two short stories by Flannery O'Connor to explore D. W. Winnicott's theory of early childhood development. This thesis proposes that the "inherited potential" of the individual is determined by the quality of the early maternal environment, especially during the period of Winnicott's first two paradoxical stages of development: Absolute Dependence and Relative Dependence. The mother-adult/child relationships in O'Connor's two short stories "Good Country People" and "The Enduring Chill" serve as case studies to examine the ramifications of "not good-enough" mothering on the in...

This study examined emergency management certification programs in order to understand what the training requirements for state emergency management certification reveal about the core functions of emergency management as conducted by emergency managers working in local jurisdictions. Based on practices in the 23 certification programs managed by state emergency management agencies or professional associations at the time of the study, qualitative content analysis identified a range of core functions practiced by those programs that specified training requirements in terms of specific courses...

This dissertation studied the correlation between the number of hours spent by seniors on the internet in three categories of online activities and the seniors' levels of depression. The subjects were men and women age fifty-five and older living in an active retirement community. The three categories of online activities were communications activities, information-gathering activities, and personal transactions. Number of hours spent online was measured by a self-reporting questionnaire. Level of depression was measured by administration of the Beck Depression Inventory-II. Spearman's rho was...

The Agulhas Retroflection transfers heat, salt and vorticity from the Indian Ocean to the South Atlantic. The transfer is accomplished by discrete meso-scale features and by the advection of a water column of mixed Atlantic and Indian Ocean origins. The objectives of this thesis are to measure the strength of the Agulhas-South Atlantic (ASA) exchange and to develop a generalized method for the measurement of mass and thermohaline fluxes. First, ASA mass and energy fluxes are estimated by using sea surface height (SSH) anomalies from satellite altimetry to monitor Agulhas eddies, a signifi...

Little is known about student success in online learning environments, especially how the predisposing characteristics that the learner brings to the learning environment may differentially affect student outcomes. This study explored the question of whether a student's "readiness" to be a self-directed learner is a predictor of student success in an online community college curriculum. The specific goal of this investigation was to determine whether there was a significant relationship between self-directed learning readiness-as measured by Guglielmino's (1977) Self-Directed Learning Readin...

This dissertation argues that conduct and behavior were believed essential for determining one's post-mortem fate from the earliest periods of both ancient Egypt and ancient Greece. Part one of this four-part study examines Plato's eschatological myths and provides a complete catalog and brief discussion of all references in them to conduct and behavior that affect one's fate in the afterlife. Part two traces the evolution of the concept of the afterlife from Homer to the Dramatists, also cataloging all references to the afterlife that mention conduct and behavior. This part of the study de...
