The use of outcome measures by occupational therapists to establish the effectiveness of treatment is important. The Jebsen-Taylor Hand Function Test (JHFT) was identified as a standardised assessment suitable for the evaluation of outcomes related to the treatment of hand function. This study established norms for this test on 120 normal, ethnically diverse South Africans between the ages of 20 and 59 years. Statistically significant differences were found between the original norms published by Jebsen et al (1) and the South African sample for males and females, dominant and non-dominant hands and ethnic groupings. It is postulated that gender and cultural factors may influence the speed with which different groups complete functional tasks and these must be factored in when using the JHFT as an outcome measure in South Africa. The test appears to have limited application as a norm referenced test in South Africa, but may be valuable in determining progress in therapy or research.

Thesis advisor: Arthur Madigan / This dissertation is based on the claim that Taylor, in his immense philosophical writings, looks for the unifying forces, principles, and those desires in the human agent that can transform modern partial comprehension of reality into a new collage, i.e. a deeper and more meaningful picture of who we are and what is most essential for us. I argue that Taylor in his reflection on modernity adopts Hegel's concern for how to unite two ideals - radical freedom and expressive fullness. In search for an answer to Hegel's concern, Taylor repeatedly comes to the same conclusion. Adequate understanding of modernity, moral sources of modern identity, human agency, and human language, requires insertion in its context; therefore, the description of time, space, and other factors that condition modernity, is crucial. There are some aspects in Taylor's reflection on modernity that either preclude or impede the modern agent's search for fulfillment and freedom (i.e., reduction of the human sciences to the principles of the natural sciences), or open neglected or undiscovered perspectives for investigation, and offer new answers (i.e., challenge of achieving peaceful coexistence in a multicultural society). Underneath these aspects of modernity, Taylor perceives human desire to be free, authentic, and fulfilled. In the recent publications, Taylor brings into focus the closed horizons of modernity in the field of religion, especially the mainstream secularization theory. As long as modernity considers religion and spirituality as unimportant and pushes them aside from our daily life, it effectively closes off some possible answers regarding agent's fulfilment, flourishing, and freedom. It does not mean that every form of religious practice and belief brings us automatically to the goal; some might be narrow and exclusive as well, and therefore have to be examined in turn. Taylor's reflection unfolds the answer to Hegel's concern only gradually. In order to be free, fulfilled, and have a meaningful life, no dimension of human existence can be excluded, all dimensions remain to be examined. / Thesis (PhD) — Boston College, 2012. / Submitted to: Boston College.

Thesis advisor: Bonnie Jefferon / Kanye West is a musical artist whose shocking public statements often remain in the news for weeks on end. Throughout the past six years of his extremely successful career, at least three of these public acts have received tireless media coverage both for their perceived offensiveness, and for their direct connection to larger societal issues. This project examines three statements: (1) West’s 2005 claim during Hurricane Katrina that “[President] George Bush doesn’t care about Black people;” (2) the moment in 2009 when West stormed the MTV Video Music Awards stage during singer Taylor Swift’s acceptance speech and grabbed her microphone, stating that he would let her finish, “but Beyoncé had one of the best videos of all time;” and (3) West’s 2010 appearance on NBC’s Today Show and the series of angry messages he posted to his Twitter page claiming that the interviewer, Matt Lauer, tried to “force” his answers. These statements are analyzed to determine whether West may have unwittingly employed the rhetorical method Theodore Windt describes as the diatribe. The paper concludes that West’s statements in 2005 and 2010 meet the criteria for the diatribe, using a shocking act or message to catalyze important discussion of major problems existing in society. However, West’s 2009 incident fails to meet the criteria, and cannot be categorized as a diatribe, but instead as simply an offensive act that provided no greater benefit to society. The process of these analyses may serve as a way to examine future celebrity statements to determine whether certain individuals are striving to elevate society or, through their offenses, may be adding to a cultural downfall. / Thesis (BA) — Boston College, 2011. / Submitted to: Boston College.

Thesis advisor: Thomas Groome / Western culture idealizes the quest for authenticity as a significant life project. This culture of authenticity is characterized by the understanding that it is important for each person to search for their unique life expression and purpose, even as larger social, political, religious, and other such frameworks are generally suspected of being in conflict with or in opposition to the truly authentic. Further, the forces of secularism and pluralism have allowed for a wide dissemination of varied and often conflicting views about what constitutes an authentic way of being in the world. Within such a secular-pluralistic milieu, the prevalence of different and often competing views is particularly acute in regards to contemporary images and concepts of God, particularly as these relate to the (post)modern quest for authenticity. For instance, while our culture's widespread suspicion that larger religious frameworks inhibit authenticity has in part led to a significant rise in the numbers of those unaffiliated with any religious tradition, a majority of the unaffiliated still claim to believe in God. This somewhat paradoxical phenomenon can be traced back to the secular-pluralist profusion of various understandings and expressions regarding the meaning of "God." Within these circumstances, "authentic" relation to the divine is often seen as a highly individualized and even subjective concern; as something having to do with what best expresses a person's own feelings and inner personal world regarding the unique meaning of their life. This dissertation posits that Catholic religious and theological education needs to take seriously the importance our culture accords to the quest for authenticity and to actively work against its individualistic, expressivist, and subjectivist tendencies. Unmasking the illusion that authenticity requires dismissing larger frameworks, such as religious tradition, I posit that it is only within larger frameworks that we are able to discern the more from the less authentic. In terms of images and conceptions of God then, I argue that a Catholic education for today requires retrieving the Catholic Intellectual Tradition's discipline of philosophical theology so as to provide students with the resources necessary for discerning the true, living God from among the jumble of ideas and images on offer within secular-pluralism. Ch. 1 provides an historical overview of the culture of authenticity and in the process defines the latter and its relation to secular-pluralism and to the proliferation of images and conceptions of God. Philosophical theology is introduced as potentially necessary component of a Catholic education that seeks to help students discern the authentic, or true God. Ch. 2 takes up the question of authenticity as related to conflicting ideas about the truth of existence and in this light offers an understanding of truth as engaged, relational, and non-absolute. This understanding grounds the contemporary philosophical theological approach presented in chapters four and five. First, however, Ch. 3 looks at the thought of Thomas Aquinas as standard for the field of philosophical theology and therefore as necessary for (creatively) retrieving for its usefulness today. Chapter 4 begins the process of retrieval by outlining the ways in which W. Norris Clarke's Thomistically based "Inner" and "Outer" Paths to God provide elements for a contemporary philosophical theology. Ch. 5 continues in this vein as it turns to the work of Elizabeth Johnson to elucidate the socioeconomic, political, and cultural aspects that must be attended to by any contemporary philosophical theology. Ch. 6 proposes Thomas Groome's Shared Christian Praxis approach to Christian religious education as theoretically and practically compatible with a contemporary philosophical theology and therefore as the most suitable pedagogical approach to educating from and for faith. I conclude the dissertation with a brief reflection on what lessons philosophical theology has to offer to Catholic religious and theological education as a whole. / Thesis (PhD) — Boston College, 2014. / Submitted to: Boston College.

We present an experimental study on the behavior of bubbles captured in a Taylor vortex. The gap between a rotating inner cylinder and a stationary outer cylinder is filled with a Newtonian mineral oil. Beyond a critical rotation speed (ω[subscript c]), Taylor vortices appear in this system. Small air bubbles are introduced into the gap through a needle connected to a syringe pump. These are then captured in the cores of the vortices (core bubble) and in the outflow regions along the inner cylinder (wall bubble). The flow field is measured with a two-dimensional particle imaging velocimetry (PIV) system. The motion of the bubbles is monitored by using a high speed video camera. It has been found that, if the core bubbles are all of the same size, a bubble ring forms at the center of the vortex such that bubbles are azimuthally uniformly distributed. There is a saturation number (N[subscript s]) of bubbles in the ring, such that the addition of one more bubble leads eventually to a coalescence and a subsequent complicated evolution. Ns increases with increasing rotation speed and decreasing bubble size. For bubbles of non-uniform size, small bubbles and large bubbles in nearly the same orbit can be observed to cross due to their different circulating speeds. The wall bubbles, however, do not become uniformly distributed, but instead form short bubble-chains which might eventually evolve into large bubbles. The motion of droplets and particles in a Taylor vortex was also investigated. As with bubbles, droplets and particles align into a ring structure at low rotation speeds, but the saturation number is much smaller. Moreover, at high rotation speeds, droplets and particles exhibit a characteristic periodic oscillation in the axial, radial and tangential directions due to their inertia. In addition, experiments with non-spherical particles show that they behave rather similarly. This study provides a better understanding of particulate behavior in vortex flow structures. / Singapore-MIT Alliance (SMA)

In this thesis, we propose different CORDIC architectures which solve the problems of long-latency in traditional pipeline CORDIC and the large-area cost in table-based CORDIC. The original table-based CORDIC can be divided into two stages, coarse stage and fine stage. We also propose the three-stage architectures, composed of traditional pipeline CORDIC, Rom/Multiplier architecture and linear approximation. Detailed analysis and estimation in area and latency of these different two-stage and three-stage architectures with different bit accuracy are given in order to determine the best architecture design for a particular precision. Finally, we choose one of the architectures to implement, compare the results, and show its applications.

Experiments and direct numerical simulations (DNS) have been performed to examine the e¤ects of initial conditions on the dynamics of a Rayleigh-Taylor unsta- ble mixing layer. Experiments were performed on a water channel facility to measure the interfacial and velocity perturbations initially present at the two-fluid interface in a small Atwood number mixing layer. The experimental measurements have been parameterized for use in numerical simulations of the experiment. Two- and three- dimensional DNS of the experiment have been performed using the parameterized initial conditions. It is shown that simulations implemented with initial velocity and density perturbations, rather than density perturbations alone, are required to match experimentally-measured statistics and spectra. Data acquired from both the exper- iment and numerical simulations are used to examine the role of initial conditions on the evolution of integral-scale, turbulence, and mixing statistics. Early-time turbu- lence and mixing statistics are shown to be strongly-dependent upon the early-time transition of the initial perturbation from a weakly-nonlinear to a strongly-nonlinear flow.
