The extrusive and intrusive members of the St. Helena rock suite (SHRS) are formed in an intra-oceanic plate tectonic setting as part of two shield volcanoes. The SHRS vary from picrobasalts to phonofites. The former represent mantle derived melts, whereas the remainder of the suite have undergone differing degrees of crystal fractionation. A stratigraphic framework is developed to illustrate temporal geochemical variations over 2 Ma of subaerial activity. This is accomplished in conjunction with a detailed field study of the SHRS by Baker(1968) which is shown to be largely accurate. It is demonstrated that ascending magma batches are substantially modified by crystal fractionation and subsequent alteration processes. Petrogenetic modelling shows that the genesis of the SHRS is consistent with small degree (1-10%) melting of an olivine - clinopyroxene - orthopyroxene - garnet source containing a residual K-rich phase. Combined Sr-Nd-Pb isotope and fractionation corrected trace element data for fresh rocks enable consideration of changing thermal and chemical fluxes impinging on and interacting with the base of the lithosphere over a period of at least 2 Ma. The existence of two geochemically distinct components in the source region is indicated. A H/MU (high 238U /104Pb)c omponent has extremely radiogenic Pb isotopes (206Pb/104Pb> 20.8) with 143Nd/'44Nd and 87S8r,6 Sr displaced below the mantle array. The complementary depleted component has less radio genic Pb and Sr isotopic compositions and more radio genic Nd compositions. The limited variation of geochemical compositions in the SHRS (caused by mixing of these components) is attributed to the dissimilarity of the components in terms of their trace element abundance and their similarity in terms of ratios of highly incompatible elements. Coupled trace element and isotope variations are evident during the activity of each volcano. During shield development an increase in incompatible trace element enrichment occurs. This is coupled to a decrease in 143Nd/'44Nd, whilst Sr and Pb become progressively more radiogenic. The time dependent variations are thought to be consistent with mixing and melting processes occurring at the base of, or within the lithosphere. A decrease in the signature of the depleted component at the end of activity of the NE volcano and SW volcano is the inferred result of a decreasing thermal flux acting on the base of the lithosphere. With lower heat input less fusion of the depleted component (from the asthenosphere or lithosphere) occurs resulting in an increased H/MU signature in the erupted products through time. Previous explanations for the development of the dominant HIMU component are critically reviewed by considering shared isotope and trace element characteristics for HIMU OIB. U-Th-Pb systematics suggest the HIMU component has remained discrete from other mantle components for approximately 2 Ga. The fractionation event producing the H/MU component is shown to cause an increase in U/Pb and a decrease in Rb/Sr and Th/U.. This is thought to be consistent with a model suggested by Hofmann and White(1980,1982). in which HIMU represents ancient recycled altered oceanic crust. It is demonstrated that other models are less tenable. It is thought that the HIMU characteristics necessitate modification of oceanic crust in subduction zones in addition to the geochemical changes caused by hydrothermal alteration of oceanic crust.

Thesis advisor: Brian Dunkle / Thesis advisor: Margaret Schatkin / The patience of God is a predominant theme in the homilies of St. John Chrysostom. Indeed, for Chrysostom, patience is not simply a human virtue but a diving attribute, an expression or reflection of God's φιλανθρωπία; it must therefore be understood in such a way that goes beyond its usual association with suffering, passivity, and powerlessness. Whereas patience in English, like patientia in Latin, is a somewhat ambiguous term, having both an active and a passive sense, the Greek language allows both for more precision and for greater depth and richness. This thesis will offer first an elaboration of Chrysostom's understanding of God's patience and then an exploration of how patience as a diving attribute colors and transforms not only our appreciation of Christ's patience but also the importance of practicing the virtue of patience in our own lives. In the effort to articulate Chrysostom's theology of patience, the primary concern of this thesis lies with the philosophical and theological concept of patience rather than with the lexical exactitude for which the translator always strives. The first chapter is theological in emphasis as it considers the description of God as μακρόθυμος in the Septuagint and examines Chrysostom's discussion of God's μακροθυμία in a selection of his homilies on Genesis and the Psalms. The second chapter is christological in emphasis as it analyzes Chrysostom's use of the term πραότης - whch in a (pagan) philosophical context is synonymous with μακροθυμία but in a biblical context has a very different meaning - in his exegesis of Christ's Passion in his Homilies on Matthew. Finally, the third chapter is anthropological in emphasis as it takes up the question of the imitation of God's μακροθυμία and Christ's πραότης as the way to restore and strengthen the divine likeness in the human person. Far from being a mere intellectal construct or the topic of purely academic debate, Chrysostom's theology of patience has much to teach us in regards to approaching current social and cultural reality. / Thesis (STL) — Boston College, 2022. / Submitted to: Boston College.

Cardiovascular disease is one of the most prevalent causes of death which has a high mortality rate. If identified early and treated appropriately, the mortality in patients with cardiovascular disease can be hugely reduced. For several decades, 12-Lead ECG has been the standard technique used to identify ischemia, and recent studies have shown that intracardiac electrogram has many benefits over external monitoring such as holter. ST Monitoring feature has been added to St. Jude Medical intracardiac cardioverter defibrillators (ICD) to leverage the ECG technology for identifying cardiovascular disease. This algorithm monitors the intracardiac electrogram to detect and report patterns which could be related to ischemic events. This feature is expected to enhance the process of identifying ischemia and infarction, and provides long-term management of the disease. In order to support the new implantable devices with ST Monitoring capability, the programmer software was updated to support this new feature in the device. This thesis discusses the work on the programmer. Chapter 1 begins with a background of how monitoring technology in an implantable device can benefit the patients facing high risk of myocardial infarction. Chapter 2 states the objective for the work on the programmer. Chapter 3 describes the implementation and the application of this feature. Conclusion and future development are discussed in Chapter 5.

The amalagamation of St. Mary's College and St. Joseph's High School, Lismore was a process that began in 1965 when a decision was made to combine Senior classes for the first Higher School Certificate curriculum. There was no thought of amalgamation in 1965 but the decision made then lead to the developments of 1977. Increasing enrolments and the need for a building programme set the scene for a merger of Junior classes and the introduction of coeducation throughout the schools. This process extended from 1977 to 1981. It was a period of conflict and resistance to change but it laid the foundation for the complete amalgamation of the schools to form Trinity Catholic College in 1985. The amalgamation process provides a study of decision-making in a Catholic school context. Changes in the Church, Catholic schools and Religious Orders are reflected in the changes in the way that decisions were made at the three key-points in the story. The study draws attention to the fact that in amalgamations of schools much of the planning is done in terms of the present schools rather than for the new school which is always twice as large and much more complex. The non-educational aspects of amalgamation are also considered because they are a time-consuming but important part of the planning. This study shows the importance of rituals in laying the old schools to rest so that the new school may come into being. A visible indication that things are different is essential when the students, staff and buildings remain as they had been. Since amalgamations are becoming more common as student numbers decline some lessons learned over the past twenty years are recorded so that others may benefit from them.
