    We propose the concept of the minimal photo hull which can produce the most consistent photographs among all of the photo hulls. In addition, it is also one of the optimal shapes making the minimal consistent level be the largest. Experimental results show that the minimal photo hull can be successfully applied for generation of convincing novel views. I

    This collection of essays explores the metaphysical thesis that the living world is not ontologically made up of substantial particles or things, as has often been assumed, but is rather constituted by processes. The biological domain is organized as an interdependent hierarchy of processes, which are stabilized and actively maintained at different timescales. Even entities that intuitively appear to be paradigms of things, such as organisms, are actually better understood as processes. Unlike previous attempts to articulate processual views of biology, which have tended to use Alfred North Whitehead’s panpsychist metaphysics as a foundation, this book takes a naturalistic approach to metaphysics. It submits that the main motivations for replacing an ontology of substances with one of processes are to be looked for in the empirical findings of science. Biology provides compelling reasons for thinking that the living realm is fundamentally dynamic and that the existence of things is always conditional on the existence of processes. The phenomenon of life cries out for theories that prioritize processes over things, and it suggests that the central explanandum of biology is not change but rather stability—or, more precisely, stability attained through constant change. This multicontributor volume brings together philosophers of science and metaphysicians interested in exploring the consequences of a processual philosophy of biology. The contributors draw on an extremely wide range of biological case studies and employ a process perspective to cast new light on a number of traditional philosophical problems such as identity, persistence, and individuality

    The peril and promise of infill for Cincinnati's Over-The-Rhine: how new construction can ruin or resue a nationally significant historic neighborhood

    Get PDF
    Over-the-Rhine (OTR) in Cincinnati, Ohio is among the largest and most significant historic districts in the U.S., designated as a historic district in both the National Register of Historic Places and locally. Growing interest in revitalizing the neighborhood has spurred historic rehabilitation and investment in new construction (i.e., “infill”) on the neighborhood’s many vacant lots -- especially since the early 2000s. While OTR is significant for its Italianate architecture and its remarkably cohesive character, infill is often of a different character, threatening the integrity and identity of the neighborhood’s setting. Owing to decades of policy decisions and a deeply ingrained philosophy that infill must stand in contrast to its historic neighbors, the character of OTR is being eroded by new construction and may be destroyed if the trend continues. This thesis analyzes both the policy and theory that have contributed to this phenomenon, concluding that the appropriate approach to infill in OTR is one that favors continuity of architectural character over contrast with historic fabric. An objective rubric for appropriateness of infill in OTR is established based on empirical elements of architectural character. The rubric is applied to 29 case studies of infill projects in OTR. Five additional case studies outside of but relevant to OTR are also included to provide an external frame of reference. Based on the findings of the case studies, the thesis concludes with recommendations for how to mitigate the adverse effects of existing incompatible infill and ensure that future infill is more appropriate to the character of OTR.Thesis (M.S.

    Mindful Mending: The Repair of Thought and Action Amidst Technologies

    Get PDF
    My thesis is that the concept and practice of repair, properly understood and circumscribed, can serve to: (1) specify a responsibility to care for individuals who are cognitively dependent on particular configurations of technologies and suffer cognitively significant harms following damage to various technologies, and (2) to act as a standard by which to regulate the design, implementation, and selection of technologies available for human use and appropriation. I begin (Chapters One and Two) by providing a critical investigation of the concept and practice of repair. In Chapters Three and Four, I set forth a proposal to consider what I term cognitive-agentic repair as the mindful mending of agentic skills/autonomy competency by way of those constitutive cognitive processes that are extended/situated in objects and arrangements of objects that constitute particular material spaces and places (home, workplace). As such, I argue that when either intentional or unintentional harms are committed against individuals who are cognitively situated in the world, there is a prima facie responsibility to attempt the specific act of cognitive-agentic repair so as to support the possibility of personal autonomy. To justify this ethical responsibility, I advance an account of human persons that is grounded in both feminist philosophy and recent work in the cognitive sciences on the hypotheses of extended and embedded cognition. I then move to consider how my account of repair can constructively inform the design, implementation, and selection of particular technologies by acting as a regulative standard. This analysis is divided into two parts: (1) a theoretical construction that utilizes work in the philosophy of technology to distinguish the pattern of those technologies that would facilitate cognitive-agentic repair (Chapter Five) and (2) a practical application to telemedical/telehealth technologies (Chapter Six)

    The struggle over, and impact of, media portrayals of Northern Ireland

    Get PDF
    This thesis examines the process of mass communication from media strategies to audience belief in relation to the conflict in Ireland. It documents the media strategies used by the various actors and participants in the conflict, from the Northern Ireland Office, Royal Ulster Constabulary, Foreign Office and Army to Sinn Fén and the Irish Republican Army, via the Ulster Defence Association, other political parties, Civil liberties and human rights organisations and many others. It reveals the continuing disinformation efforts of the British government, examines how source organisations interact with journalistsw, how journalists and their editors operate and looks at the outcome of their endeavours by analysing international coverage of the Northern Ireland conflict. Finally, the research examines the reception of media information amongst people living in Northern Ireland and Britain. Key questions here included the extent to which `violence' acted as a key organising category in British perceptions of the conflict and the effectiveness of propaganda in structuring public (mis)understandings

    A Samaritan State Revisited

    Get PDF
    Canada’s foreign aid programs are an area of ongoing interest, yet there is little knowledge of Canada’s 70-year aid history, the historic forces that have shaped Canadian aid policy, and the many complex factors that affect Canada’s future foreign aid policy. A Samaritan State Revisited brings together a refreshing group of emerging and leading scholars to reflect on the history of Canada’s overseas development aid. Addressing the broad ideological and institutional origins of Canada’s official development assistance in the 1950s and specific themes in its evolution and professionalization since the 1960s, this collection is the first to explore Canada’s history with foreign aid with this level of interrogative detail. Extending from the 1950s to the present and covering Canadian aid to all regions of the Global South, from South and Southeast Asia to Latin America and Africa, these essays embrace a variety of approaches and methodologies ranging from traditional, archival-based research to textual and image analysis, oral history, and administrative studies. A Samaritan State Revisited weaves together a unique synthesis of governmental and non-governmental perspectives, providing a clear and readily accessible explanation of the forces that have shaped Canadian foreign aid polic

    Tradition and innovation in the poetry of Gary Snyder, 1952-1982

    Get PDF
    Previous studies of the poetry of Gary Snyder have frequently concentrated upon the surface, esoteric nature of his work, claiming for it a uniqueness which overlooks his debt to tradition. This thesis proposes that Snyder's poetry can be divided into two modes, the mythic and the lyric, each a contribution to well-established modern American poetic traditions. The discussion of the mythic poems traces Snyder's indebtedness to the Modernist long poem and, in particular, sees T. S. Eliot's The Waste Land as an important structural model for Myths & Texts, a poem which is also closely related to Joseph Campbell's delineation of the quest monomyth. In the chapter on the lyric poems, it is suggested that Snyder is one of the inheritors of an experimental lyric tradition initiated by the work of Ezra Pound and William Carlos Williams. Both chapters also indicate how such past models have given Snyder's poetry a stability which allows for a measure of profitable innovation. Examples which are isolated are the extensive use of American Indian oral literature in the mythic poems, and the original application of aspects of Chinese poetry and poetics in the lyrics. These two chapters take the study of the poetry up to 1968. This date, which marks Snyder's return to the United States after a long period of residence in Japan, is seen as a watershed after which his work enters a critical and problematical phase.The principal objective of the chapter on the later poems is to show that when Snyder turns away from his Modernist inheritance to seek the role of overt social prophet, he sacrifices much of his earlier technical accomplishment, thus making further innovation more questionable. As part of its researches, the thesis also provides the first comprehensive bibliography of Snyder, including a complete list of his uncollected work
