Thesis advisor: Frederick Lawrence / This work argues that religious conversion sublates moral conversion and also, de facto, serves as a necessary foundation for moral conversion. Religious conversion acts this way by transforming the religiously converted subject's feelings. Through this radical change in the subject's motivation, and the consequent change in the kinds of meanings that constitute the subject, religious conversion also transforms the nature of the human good of which the subject is a part. It thereby provides the basis for the right ordering of the human good toward transcendent value and a supernatural end. / Thesis (PhD) — Boston College, 2009. / Submitted to: Boston College.

Thesis advisor: Frederick Lawrence / The first chapter begins by delineating Lonergan’s philosophy of development. It then applies this philosophy to a range of literature on grace and discerns, in the historical data, a basic line of intellectual progress. For this reason, this chapter implements a genetic method. More specifically, the chapter proposes an explanatory framework for understanding the contemporary transposition of scholastic metaphysics. Special attention is placed on the notion of grace as experience in relation to the evolution of theology as a science. The first chapter implements a genetic method to chart the developments in the history of the theology of grace. The last section of that chapter sketches the basic contours of a development that enabled a transposition from the second to the third stage of meaning—a development that made possible a description of grace in terms of consciousness. The second chapter addresses the question of grace and consciousness in the context of Lonergan’s thought. In this chapter, I bring to light the complexities and challenges of identifying and describing grace as a datum of human experience. I also attempt to offer the Lonergan scholar some guidance by developing a set of normative criteria that will assist him in navigating these complexities and surmounting these challenges. The chapter is not an exercise in foundational theology but is written from a dialectical and methodological viewpoint. The dialectical and methodological work of the second chapter will prepare for the task of the third chapter. Chapter three compares Rahner’s and Lonergan’s theologies of grace; it focuses on a comparison of Lonergan’s notion of ‘being-in-love unrestrictedly’ and Rahner’s notion of the ‘supernatural existential’ in order to clarify their respective positions and to demonstrate an affinity in their writings on grace. Chapter four uses Rahner’s and Lonergan’s account of grace in terms of experience, developed in chapter three, to work out a theology of religion that responds to the challenges posed by post-modernism. My thesis in chapter four is that Rahner’s and Lonergan’s theologies of grace can ground the notion of a common consciousness of grace and take seriously the claim of a genuine variety of religious experiences. / Thesis (PhD) — Boston College, 2009. / Submitted to: Boston College.

The Gravity Recovery and Climate Experiment (GRACE) mission is a breakthrough Earth science mission launched in the spring of 2002 that uses satellite-to-satellite tracking (SST) to map the Earth gravity field. In this framework, the non-uniform gravity distribution is inferred using the range change experienced between two satellites. The range change is measured using a microwave K-band ranging system, and non-gravitational forces are accounted for using accelerometer (ACC) data. The vector-offset between the satellite center of mass (CM) and the K-band phase center represents the correction between measured and modeled ranging data. In addition, the offset between the satellite CM and the ACC proof-mass multiplies the attitude angles, rates, and jitter which in turn add spurious signals to the ACC output. For both of these reasons, proper knowledge and control of attitude behavior is vital to successful mission performance. An examination of the GRACE attitude control system (ACS) is presented in this study. The GRACE ACS system is composed of a PD control law, star camera sensing as the knowledge source, cold-gas thrusters as primary actuators, and magnetic torque rods as supplementary actuators. The dependencies inherent in the ACS are inferred using a sensitivity analysis performed on a simulation model of the GRACE science mode ACS. The results from this sensitivity study are applicable to the general controller class of which the GRACE ACS system is an exemplar. In this study, the modeled attitude data quality is most sensitive to star camera measurement noise. It is hypothesized that this is because star cameras are used as the sole knowledge source in the ACS scheme. In contrast, the experimental results associated with magnetometer, thruster, and magnetic torque rod perturbations did not significantly affect attitude quality. However, these perturbations do cause thruster activity to significantly magnify. This results in higher attitude acceleration PSD for the frequency band in which time-variable gravity components are captured. A number of future experiments can be performed to improve both attitude quality performance and frequency-based magnifications. Examples include sensor fusion studies, reaction wheel versus thruster assessment, and gravity field estimation sensitivity in response to attitude quality degradation. / text
