Substance and Person in Tertullian and Augustine

The doctrine of the Trinity has been a focal point of Christian thinking throughout Church history. While the term “Trinity” does not appear in the biblical text, it is still a vital Christian doctrine. The doctrine, however, has not come without controversy. Various understandings of the doctrine have been presented throughout Church history. Tertullian (ca. 160-220 AD) and Augustine (354-430 AD) represent two of the foremost theologians to discuss the issue. Tertullian was one of the first to thoroughly examine the doctrine. He coined the terms “substance” and “person” in his discussion of the doctrine. These terms would come to have a lasting impact on Christian theology. The council of Nicaea would show this commitment to Tertullian’s distinctions. Augustine also reflects his debt to Tertullian’s ingenuity yet makes significant moves to further develop the doctrine. Each of the theologians wrote in a particular context challenging the heretics of their day. They used biblical argumentation and their own philosophical commitments to present their understanding of the doctrine. This paper examines Tertullian’s use of the terms and then compares and contrasts them with Augustine’s use

Plant phenology and seasonal nitrogen availability in Arctic snowbed communities

Thesis (M.S.) University of Alaska Fairbanks, 2006This study was part of the International Tundra Experiment (ITEX) and examined the effects of increased winter snow depth and decreased growing season length on the phenology of four arctic plant species (Betula nana, Salix pulchra, Eriophorum vaginatum, and Vaccinium vitis-idaea) and seasonal nitrogen availability in arctic snowbed communities. Increased snow depth had a large effect on the temporal pattern of first date snow-free in spring, bud break, and flowering, but did not affect the rate of plant development. By contrast, snow depth had a large qualitative effect on N mineralization in deep snow zones, causing a shift in the timing and amount of N mineralized compared to ambient snow zones. Nitrogen mineralization in deep snow zones occurred mainly overwinter, whereas N mineralization in ambient snow zones occurred mainly in spring. Concentrations of soil dissolved organic nitrogen (DON) were approximately 5 times greater than concentrations of inorganic nitrogen (DIN) and did not vary significantly over the season. Projected increases in the depth and duration of snow cover in arctic plant communities will likely have minor effects on plant phenology, but potentially large effects on patterns of N cycling

Seeing Through the Invisible Pink Unicorn

This paper explores the quasi-religious aspects of the Invisible Pink Unicorn (IPU), an internet based spoof of religion. IPU message boards situate a moral orientation in an ongoing interactional process that sacralizes parody and an idealized form of “free thinking.” We employ content analysis and grounded theory to argue that IPU writers’ parody of religion serves as a ritual act and conclude our discussion by considering the implications of the findings for the literature on ritual

Exactly solved models on planar graphs with vertices in Z3\mathbb{Z}^3

It is shown how exactly solved edge interaction models on the square lattice, may be extended onto more general planar graphs, with edges connecting a subset of next nearest neighbour vertices of $\mathbb{Z}^3$. This is done by using local deformations of the square lattice, that arise through the use of the star-triangle relation. Similar to Baxter's Z-invariance property, these local deformations leave the partition function invariant up to some simple factors coming from the star-triangle relation. The deformations used here extend the usual formulation of Z-invariance, by requiring the introduction of oriented rapidity lines which form directed closed paths in the rapidity graph of the model. The quasi-classical limit is also considered, in which case the deformations imply a classical Z-invariance property, as well as a related local closure relation, for the action functional of a system of classical discrete Laplace equations.Comment: 34 pages, 18 figures, v2: typos corrected, and additional comment
