Between Physicalism and the New Dualism: The Moral Relevance of the Human Body for Catholic Ethics

One could argue the remarkable changes to the landscape of Catholic moral theology over the course of the twentieth century were unparalleled in the history of the Church. Animated by anthropological and pastoral concerns, competing schools of Catholic ethicists introduced novel interpretations of natural law that sought to do greater justice to the entirety of the human person, not merely the physical dimension that tended to be emphasized throughout the manualist era. These unique and competing perspectives that emerged in the middle of the 1900s, found in the revisionist school and the New Natural Law Theory school, shaped the topography of Catholic moral theology in unprecedented ways. Previously unknown methods of moral decision-making came to dominate works of Catholic scholars; this was accompanied by radically new conclusions reached by the dominant revisionist school. It is these changes that are of interest to the current project. More precisely, this work seeks to reevaluate the present situation within Catholic moral theology through an anthropological lens. Both revisionist and traditionalist scholars alike explicitly operate with the intention of providing ethical systems that correspond to the holistic (i.e., nondualist) picture of the human person emphasized at the Second Vatican Council. But do these theories actually meet their nondualist anthropological standard? This work argues that they do not. It will be argued that the concern to avoid physicalist mistakes caused an overcorrection. In the revisionist school in particular, there has arisen a new dualism whereby the moral body has become irrelevant for Catholic ethical theories. The goal of this project, then, is to examine this dualism and propose modest but necessary principles required for finding a morally relevant place for the human body within Catholic moral theology. If the human body makes up an essential aspect of the human person, then this ought to be reflected in the methodological structure of Catholic ethics. By integrating the principles offered in this work into modern ethical theories, the diversity of thought reflected within Catholicism can remain while simultaneously finding a moral relevance of the human body

Materials and Textile Architecture Analyses for Mechanical Counter-Pressure Space Suits using Active Materials

Mechanical counter-pressure (MCP) space suits have the potential to improve the mobility of astronauts as they conduct planetary exploration activities. MCP suits differ from traditional gas-pressurized space suits by applying surface pressure to the wearer using tight-fitting materials rather than pressurized gas, and represent a fundamental change in space suit design. However, the underlying technologies required to provide uniform compression in a MCP garment at sufficient pressures for space exploration have not yet been perfected, and donning and doffing a MCP suit remains a significant challenge. This research effort focuses on the novel use of active material technologies to produce a garment with controllable compression capabilities (up to 30 kPa) to address these problems. We provide a comparative study of active materials and textile architectures for MCP applications; concept active material compression textiles to be developed and tested based on these analyses; and preliminary biaxial braid compression garment modeling results.United States.

Natural selection shaped the rise and fall of passenger pigeon genomic diversity.

The extinct passenger pigeon was once the most abundant bird in North America, and possibly the world. Although theory predicts that large populations will be more genetically diverse, passenger pigeon genetic diversity was surprisingly low. To investigate this disconnect, we analyzed 41 mitochondrial and 4 nuclear genomes from passenger pigeons and 2 genomes from band-tailed pigeons, which are passenger pigeons' closest living relatives. Passenger pigeons' large population size appears to have allowed for faster adaptive evolution and removal of harmful mutations, driving a huge loss in their neutral genetic diversity. These results demonstrate the effect that selection can have on a vertebrate genome and contradict results that suggested that population instability contributed to this species's surprisingly rapid extinction

Going Coastal: Shared Evolutionary History between Coastal British Columbia and Southeast Alaska Wolves (Canis lupus)

Many coastal species occupying the temperate rainforests of the Pacific Northwest in North America comprise endemic populations genetically and ecologically distinct from interior continental conspecifics. Morphological variation previously identified among wolf populations resulted in recognition of multiple subspecies of wolves in the Pacific Northwest. Recently, separate genetic studies have identified diverged populations of wolves in coastal British Columbia and coastal Southeast Alaska, providing support for hypotheses of distinct coastal subspecies. These two regions are geographically and ecologically contiguous, however, there is no comprehensive analysis across all wolf populations in this coastal rainforest.By combining mitochondrial DNA datasets from throughout the Pacific Northwest, we examined the genetic relationship between coastal British Columbia and Southeast Alaska wolf populations and compared them with adjacent continental populations. Phylogenetic analysis indicates complete overlap in the genetic diversity of coastal British Columbia and Southeast Alaska wolves, but these populations are distinct from interior continental wolves. Analyses of molecular variation support the separation of all coastal wolves in a group divergent from continental populations, as predicted based on hypothesized subspecies designations. Two novel haplotypes also were uncovered in a newly assayed continental population of interior Alaska wolves.We found evidence that coastal wolves endemic to these temperate rainforests are diverged from neighbouring, interior continental wolves; a finding that necessitates new international strategies associated with the management of this species
