“Newter”-ing the Nicodemite: Reception of John Calvin’s Quatre sermons (1552) in Sixteenth-Century England

This dissertation examines the publication history of a single work: John Calvin’s 1552 Quatre sermons de M. Jehan Calvin traictans des matières fort utiles pour nostre temps, avec briefve exposition du Pseaume lxxxvii. Overlooked for both its contribution to Calvin’s wider corpus and its surprising popularity in English translation, successive editions of Quatre sermons display how Calvin’s argument against the behavior of so-called “Nicodemites” was adapted to various purposes unrelated to refuting religious dissimulation. The present study contributes to research in Calvin’s anti-Nicodemism by highlighting the fruitfulness of focusing on a discrete work and its reception. Borrowing a term (“Newter”) from John Field’s 1579 translation of Quatre sermons, this study’s title adumbrates its argument. English translators capitalized on the intrinsic malleability of a nameless and faceless opponent, the Nicodemite, and the adaptability of Quatre sermons’ genre as a collection of sermons to reshape—or, if you will, disfigure—both Calvin’s original foes and his case against them to advance various new agenda. Yet they were not the first to use the reformer’s sermons this way. They could have learned this from Calvin himself.

My examination of Quatre sermons opens by setting the work in the context of Calvin’s other writings and his political situation (Introduction, chapters one and two). Calvin’s unrelenting literary assault on French Nicodemism over three decades has long been recognized for its consistency and negativity. Yet scholars have tended to neglect how Calvin’s polemic against religious dissimulation could exhibit significant flexibility according to the needs of his context. Whereas Calvin’s preface promises simply to revisit his previous argument against participation in the Mass, his approach to Nicodemism in Quatre sermons seems adapted to accomplish goals beyond decrying false worship, offering a carefully-crafted apology for Calvin’s pastoral authority directed at his political situation. Repeatedly emphasizing God’s purpose to bless his children through the ministry of a rightly-ordered church, Quatre sermons marks a shift in Calvin’s anti-Nicodemite rhetoric away from purely negative critique, stressing instead God’s provision of spiritual nurture via political exile. Read in light of Calvin’s 1552 context, two audiences emerge: sermons ostensibly targeting believers in France who hid their faith also appear especially designed to silence Calvin’s foes in Geneva.

The remainder of the study examines the reception of Quatre sermons in the rapidly shifting religious and social contexts of Marian and Elizabethan England, where it appeared in more unique editions than any of Calvin’s writings besides the Institutio and the reformer’s 1542/45 Genevan Catechism. Calvin’s anti-Nicodemism has not been examined for its distinct contribution to the overall English reception of his thought. Five English versions of Quatre sermons appeared between 1553 and 1584—four of these under a Protestant queen, a situation quite different from the French context Calvin addressed. After situating Calvin’s position within the currents of Tudor Protestant anti-Nicodemism (chapter three), I place each of the five translations in its particular context, investigating prefaces, appendices, marginalia, and translation methods to discover how and why individuals used Quatre sermons (chapters four to six). Like Calvin in 1552, those who brought Quatre sermons to English readers were not primarily concerned with Nicodemism. Rather, the malleability of Calvin’s Nicodemite as polemical opponent and the flexibility of Quatre sermons as a sequence of discrete, interrelated parts made it popular with those eager to press Calvin into the service of a variety of diverse goals he could not have imagined, including turning his anti-Nicodemism against fellow members of the English church.

Allylation of intraerythrocytic hemoglobin by raw garlic extracts.

Recent studies have shown that deoxygenated human red blood cells (RBCs) converted garlic-derived polysulfides into hydrogen sulfide, which in turn produced vasorelaxation in aortic ring preparations. The vasoactivity was proposed to occur via glucose- and thiol-dependent acellular reactions. In the present study, we investigated the interaction of garlic extracts with human deoxygenated RBCs and its effect on intracellular hemoglobin molecules. The results showed that garlic extract covalently modified intraerythrocytic deoxygenated hemoglobin. The modification identified consisted of an addition of 71 atomic mass units, suggesting allylation of the cysteine residues. Consistently, purified human deoxyhemoglobin reacted with chemically pure diallyl disulfide, showing the same modification as garlic extracts. Tandem mass spectrometry analysis demonstrated that garlic extract and diallyl disulfide modified hemoglobin's beta-chain at cysteine-93 (beta-93C) or cysteine-112 (beta-112C). These results indicate that garlic-derived organic disulfides as well as pure diallyl disulfide must permeate the RBC membrane and modified deoxyhemoglobin at beta-93C or beta-112C. Although the physiological role of the reported garlic extract-induced allyl modification on human hemoglobin warrants further study, the results indicate that constituents of natural products, such as those from garlic extract, modify intracellular proteins.

Wee1-regulated apoptosis mediated by the crk adaptor protein in Xenopus egg extracts.

Many of the biochemical reactions of apoptotic cell death, including mitochondrial cytochrome c release and caspase activation, can be reconstituted in cell-free extracts derived from Xenopus eggs. In addition, because caspase activation does not occur until the egg extract has been incubated for several hours on the bench, upstream signaling processes occurring before full apoptosis are rendered accessible to biochemical manipulation. We reported previously that the adaptor protein Crk is required for apoptotic signaling in egg extracts (Evans, E.K., W. Lu, S.L. Strum, B.J. Mayer, and S. Kornbluth. 1997. EMBO (Eur. Mol. Biol. Organ.) J. 16:230-241). Moreover, we demonstrated that removal of Crk Src homology (SH)2 or SH3 interactors from the extracts prevented apoptosis. We now report the finding that the relevant Crk SH2-interacting protein, important for apoptotic signaling in the extract, is the well-known cell cycle regulator, Wee1. We have demonstrated a specific interaction between tyrosine-phosphorylated Wee1 and the Crk SH2 domain and have shown that recombinant Wee1 can restore apoptosis to an extract depleted of SH2 interactors. Moreover, exogenous Wee1 accelerated apoptosis in egg extracts, and this acceleration was largely dependent on the presence of endogenous Crk protein. As other Cdk inhibitors, such as roscovitine and Myt1, did not act like Wee1 to accelerate apoptosis, we propose that Wee1-Crk complexes signal in a novel apoptotic pathway, which may be unrelated to Wee1's role as a cell cycle regulator.

Heat balances and thermally driven lagoon-ocean exchangeson a tropical coral reef system (Moorea, French Polynesia)

© 2015. American Geophysical Union. All Rights Reserved.The role of surface and advective heat fluxes on buoyancy-driven circulation was examined within a tropical coral reef system. Measurements of local meteorological conditions as well as water temperature and velocity were made at six lagoon locations for 2 months during the austral summer. We found that temperature rather than salinity dominated buoyancy in this system. The data were used to calculate diurnally phase-averaged thermal balances. A one-dimensional momentum balance developed for a portion of the lagoon indicates that the diurnal heating pattern and consistent spatial gradients in surface heat fluxes create a baroclinic pressure gradient that is dynamically important in driving the observed circulation. The baroclinic and barotropic pressure gradients make up 90% of the momentum budget in part of the system; thus, when the baroclinic pressure gradient decreases 20% during the day due to changes in temperature gradient, this substantially changes the circulation, with different flow patterns occurring during night and day. Thermal balances computed across the entire lagoon show that the spatial heating patterns and resulting buoyancy-driven circulation are important in maintaining a persistent advective export of heat from the lagoon and for enhancing ocean-lagoon exchange.

Biological and physical interactions on a tropical island coral reef: Transport and retention processes on moorea, French Polynesia

The Moorea Coral Reef Long Term Ecological Research project funded by the US National Science Foundation includes multidisciplinary studies of physical processes driving ecological dynamics across the fringing reef, back reef, and fore reef habitats of Moorea, French Polynesia. A network of oceanographic moorings and a variety of other approaches have been used to investigate the biological and biogeochemical aspects of water transport and retention processes in this system. There is evidence to support the hypothesis that a low-frequency counterclockwise flow around the island is superimposed on the relatively strong alongshore currents on each side of the island. Despite the rapid flow and flushing of the back reef, waters over the reef display chemical and biological characteristics distinct from those offshore. The patterns include higher nutrient and lower dissolved organic carbon concentrations, distinct microbial community compositions among habitats, and reef assemblages of zooplankton that exhibit migration behavior, suggesting multigenerational residence on the reef. Zooplankton consumption by planktivorous fish on the reef reflects both retention of reef-associated taxa and capture by the reef community of resources originating offshore. Coral recruitment and population genetics of reef fishes point to retention of larvae within the system and high recruitment levels from local adult populations. The combined results suggest that a broad suite of physical and biological processes contribute to high retention of externally derived and locally produced organic materials within this island coral reef system. © 2013 by The Oceanography Society.

The island-scale internal wave climate of Moorea, French Polynesia

Analysis of five-year records of temperatures and currents collected at Moorea reveal strong internal wave activity at predominantly semi-diurnal frequencies impacting reef slopes at depths 30m around the entire island. Temperature changes of 1.5C to 3C are accompanied by surges of upward and onshore flow and vertical shear in onshore currents. Superimposed on annual temperature changes of approximately 3C, internal wave activity is high from Oct-May and markedly lower from Jun-Sep. The offshore pycnocline is broadly distributed with continuous stratification to at least 500m depth, and a subsurface fluorescence maximum above the strong nutricline at approximately 200m. Minimum buoyancy periods range from 4.8 to 6min, with the maximum density gradient occurring at 50 to 60m depth in summer and deepening to approximately 150 to 200m in winter. The bottom slope angle around all of Moorea is super-critical relative to the vertical stratification angle suggesting that energy propagating into shallow water is only a portion of total incident internal wave energy. Vertical gradient Richardson numbers indicate dominance by density stability relative to current shear with relatively limited diapycnal mixing. Coherence and lagged cross-correlation of semi-diurnal temperature variation indicate complex patterns of inter-site arrival of internal waves and no clear coherence or lagged correlation relationships among island sides. Semi-diurnal and high frequency internal wave packets likely arrive on Moorea from a combination of local and distant sources and may have important impacts for nutrient and particle fluxes in deep reef environments. © 2012 American Geophysical Union.
