The Epiphany in \u3cem\u3eA Portrait of The Artist \u3c/em\u3eas a Romantic Moment

Collected on parchment leaves, extended as stories in Dubliners, defined in Stephen Hero, and embedded in A Portrait Of The Artist, Joyce\u27s epiphanies have a long bibliographic and a confused critical history. Robert Scholes treats the epiphanies as a finite set of texts and argues that after Portrait Joyce outgrew them, using only one in Ulysses. Irene Hendry, on the other hand, argues in an early essay that Joyce had at least four epiphany techniques and that Joyce\u27s work is a tissue of epiphanies, great and small, from fleeting images to whole books, from briefest revelation in his lyrics to the epiphany that occupies one gigantic, enduring \u27moment\u27 in Finnegan’s Wake, running through 628 pages of text and then returning upon itself” (Hendry 461). While Scholes\u27 view is useful in tracing the development of specific passages, it tells us little about the epiphany as a literary motif. The second definition renders the epiphany and any comment on it vacuous, making any passage, from a line to a whole book, an epiphany. Amid such a welter of opinion it is difficult to construct a context in which to discuss the epiphany in an informative way. Shiv Kumar\u27s analysis of the epiphany as a descendant of Bergson\u27s L\u27intiution philosophique is helpful because he attempts to place the epiphany in a larger literary tradition. The epiphany, as it appears in the Portrait, belongs in a more obvious, but still useful literary context, that of the Romantic tradition

Introduction to the Symposium on Engaged Rhetoric of Science, Technology, Engineering and Medicine

This article argues for an engaged rhetoric of science, technology, engineering and medicine (RSTEM) that collaborates with science in the development and execution of research projects. It traces the emergence of an engaged RSTEM through recent disciplinary history and identifies Bruno Latour and Harry Collins and Robert Evans’ work as watershed moments that influence this commitment to collaboration. In reviewing the history of critique in the discipline, it argues that we have practical and political common ground with science that can supersede the necessity of critique. Finally, it addresses the difficult questions of why we as a discipline and as individual scholars would engage with science, what we have to contribute to scientific projects and where engaged scholars fit into interdisciplinary projects and into the credit cycle of the research university

"How Can We Act?" A Praxiographical Program for the Rhetoric of Technology, Science, and Medicine

The future of the rhetoric of science—which will increasingly take the form of a rhetoric of technology, science, and medicine (RTSM)—will be shaped by its move away from its modernist, humanistic roots in response to institutional pressures and historical contingencies. This paper advocates a “praxiographical” emphasis on the ability to intervene in science policy and other STEM-related discourses for the field of RTSM. It describes four research foci emerging from this emphasis to be used as areas of programmatic concern at an Institute for Applied Rhetoric of Science and Sustainability at the newly organized Patel College of Global Sustainability at the University of South Florida

Large-scale distribution of microbial and viral populations in the South Atlantic Ocean

Viruses are abundant, diverse and dynamic compo-nents of the marine environments and play a signi?-cant role in the ocean biogeochemical cycles. Toassess potential variations in the relation betweenviruses and microbes in different geographic regionsand depths, viral and microbial abundance and pro-duction were determined throughout the watercolumn along a latitudinal transect in the South Atlan-tic Ocean. Path analysis was used to examine therelationships between several abiotic and bioticparameters and the different microbial and viral popu-lations distinguished by ?ow cytometry.The depth-integrated contribution of microbial andviral abundance to the total microbial and viralbiomass differed signi?cantly among the differentprovinces. Additionally, the virus-to-microbe ratioincreased with depth and decreased laterally towardsthe more productive regions. Our data revealed thatthe abundance of phytoplankton and microbes is themain controlling factor of the viral populations in theeuphotic and mesopelagic layers, whereas in thebathypelagic realm, viral abundance was only weaklyrelated to the biotic and abiotic variables. The relativecontribution of the three viral populations distin-guished by ?ow cytometry showed a clear geographi-cal pattern throughout the water column, suggestingthat these populations are composed of distinct tax

Dimethylsulfoniopropionate in corals and its interrelations with bacterial assemblages in coral surface mucus

Corals produce copious amounts of dimethylsulfoniopropionate (DMSP), a sulfur compound thought toplay a role in structuring coral-associated bacterial communities. We tested the hypothesis that a linkage exists betweenDMSP availability in coral tissues and the community dynamics of bacteria in coral surface mucus. We determinedDMSP concentrations in three coral species (Meandrina meandrites, Porites astreoides and Siderastrea siderea) at twosampling depths (5 and 25 m) and times of day (dawn and noon) at Curac¸ao, Southern Caribbean. DMSP concentration(4–409 nmol cm?2 coral surface) varied with host species-specific traits such as Symbiodinium cell abundance, but notwith depth or time of sampling. Exposure of corals to air caused a doubling of their DMSPconcentration. The phylogeneticaffiliation of mucus-associated bacteria was examined by clone libraries targeting three main subclades of the bacterialDMSP demethylase gene (dmdA). dmdA gene abundance was determined by quantitative Polymerase Chain Reaction(qPCR) against a reference housekeeping gene (recA). Overall, a higher availability of DMSP corresponded to a lowerrelative abundance of the dmdA gene, but this pattern was not uniform across all host species or bacterial dmdA subclades,suggesting the existence of distinct DMSP microbial niches or varying dmdA DMSP affinities. This is the first studyquantifying dmdA gene abundance in corals and linking related changes in the community dynamics of DMSP-degradingbacteria to DMSP availability. Our study suggests that DMSP mediates the regulation of microbe

High dark CO2 fixation rates by active chemolithoautotrophic microbes along the water column (100-5000m) off Galicia (NW Iberian margin)

Thermonuclear Reaction Rate of 23Mg(p,gamma)24$Al

Updated stellar rates for the reaction 23Mg(p,gamma)24Al are calculated by using all available experimental information on 24Al excitation energies. Proton and gamma-ray partial widths for astrophysically important resonances are derived from shell model calculations. Correspondences of experimentally observed 24Al levels with shell model states are based on application of the isobaric multiplet mass equation. Our new rates suggest that the 23Mg(p,gamma)24Al reaction influences the nucleosynthesis in the mass A>20 region during thermonuclear runaways on massive white dwarfs.Comment: 13 pages (uses Revtex) including 3 postscript figures (uses epsfig.sty), accepted for publication in Phys.

Hiding in plain sight: the globally distributed bacterial candidate phylum PAUC34f. Frontiers in Microbiology, 11, (2020): 376, doi: 10.3389/fmicb.2020.00376.Bacterial candidate phylum PAUC34f was originally discovered in marine sponges and is widely considered to be composed of sponge symbionts. Here, we report 21 single amplified genomes (SAGs) of PAUC34f from a variety of environments, including the dark ocean, lake sediments, and a terrestrial aquifer. The diverse origins of the SAGs and the results of metagenome fragment recruitment suggest that some PAUC34f lineages represent relatively abundant, free-living cells in environments other than sponge microbiomes, including the deep ocean. Both phylogenetic and biogeographic patterns, as well as genome content analyses suggest that PAUC34f associations with hosts evolved independently multiple times, while free-living lineages of PAUC34f are distinct and relatively abundant in a wide range of environments.This work was funded by the United States National Science Foundation grants 1460861 (REU site at Bigelow Laboratory for Ocean Sciences), 1441717, 1335810, and 1232982 to RS, and the Simons Foundation (Life Sciences Project Award ID 510023) to RS.
