Vigiliae Christianae, Supplements, Volume: 150In this paper I want to take you on a walk through a garden. It is, to be sure, an imaginary garden; nevertheless, it bears a significance which extends beyond itself. Some of this significance concerns words and texts: for as we shall see, the garden is, amongst other things, a ‘garden of rhetoric’. The garden in question appears in the Gregory of Nyssa’s Homilies on the Song of Songs.[...
Spatiotemporal and individual drivers of variation in parasitism and immunity in wild red deer
No full textParasites are a ubiquitous presence in nature that can profoundly impact the
evolution and ecology of their hosts. Despite their longstanding interest for many
branches of mammalian biology, there are relatively few large-scale longitudinal
investigations of immunity and parasitism in large wild mammals. Furthermore, very
few studies take full advantage of longitudinal studies’ ability to examine
spatiotemporal variation, life history correlates, and fitness consequences of
immunity and parasitism simultaneously.
This thesis comprises the first parasitological and immunological investigation in the
individually-monitored study population of red deer (Cervus elaphus) on the Isle of
Rum in the Inner Hebrides, Scotland. Over the course of nine field seasons spanning
2016-2018, colleagues and I collected 2091 faecal samples from 447 identified
individuals. I examined these faecal samples for eggs and larvae of gastrointestinal
helminth parasites and protozoa. I particularly focussed on counts of three highly
prevalent helminth taxa: strongyle nematodes, the common liver fluke Fasciola
hepatica, and the tissue nematode Elaphostrongylus cervi. In addition, I adapted and
employed a method of faecal antibody quantification originally developed for use in
sheep. Samples were analysed for total immunoglobulin A (IgA) and anti-
Teladorsagia circumcincta-specific IgA, giving measures of both general and specific
immune allocation.
I used these immune and parasite measures in several analyses, making use of the
high-resolution life history, fitness, and behavioural data available for the Rum red
deer population, focussing mainly on samples collected from adult females. The
principal findings were:
1. The red deer were infected with multiple species of helminths and
protozoa, present at high prevalence but relatively low intensity. These
parasites showed seasonal patterns of infection with strong age and sex
biases, all of which varied between parasite taxa. Generally, younger
individuals had higher helminth intensities, and autumn and winter
seasons featured the lowest parasite intensities.
2. Parasite counts were repeatable within individuals. However, repeatability
varied according to the sampling timescale, with strongyle counts being
more similar within sampling trips than between trips. This implied
contrasting seasonal patterns in different individuals, so that sampling at
different times of year would give different impressions of patterns of
parasitism across the population.
3. Females that reproduced had lower antibody levels and higher parasite
intensities in the following year. However, different components of
reproduction had different costs for different immune and parasite
measures: gestation was associated with lower total IgA levels, while only
lactation resulted in increased parasite counts, implying an important role
of exposure in mediating reproduction-parasitism tradeoffs in this system.
4. I investigated the impact of reproduction, immunity, and parasitism on
fitness-related traits using path analysis. Parasite count in a given year was
found to correlate negatively with reproduction the following year,
indicating a possible cost of parasitism for multiple fitness-related traits,
above and beyond that accounted for by current reproductive status itself.
Increased anti-Teladorsagia circumcincta IgA was also found to be
associated with increased probability of reproduction, beyond any
association with strongyles themselves.
5. I quantified and controlled for spatial patterns of immunity and parasitism
using Integrated Nested Laplace Approximation (INLA) models. These
analyses revealed stark differences in the range and patterns of spatial
heterogeneity for different immune and parasite measures. However, fixed
effects remained largely unchanged by the incorporation of spatial effects,
indicating that spatial variation was unlikely to be confounding my earlier
findings.
I discuss these findings and their implications for longitudinal studies of immunity
and parasitism in wild animals and the further integration of spatiotemporal, life
history, immune, and parasite data

An Evening with Richard Claxton “Dick” Gregory, Civil Rights Activist, Nutritionist, Comedian, and Author
No full textGregory, Richard Claxton “Dick” (Born, October 12, 1932, St. Louis, Mo.), African American comedian and civil rights activist whose social satire changed the way white Americans perceived African American comedians since he first performed in public. Gregory’s autobiography, Nigger, was published in 1963 prior to The assassination of President Kennedy, and became the number one best-selling book in America. Over the decades it has sold in excess of seven million copies. His choice for the title was explained in the forward, where Dick Gregory wrote a note to his mother. “Whenever you hear the word ‘Nigger’,” he said, “you’ll know their advertising my book.” In 1984 he founded Health Enterprises, Inc., a company that distributed weight loss products. In 1987 Gregory introduced the Slim-Safe Bahamian Diet, a powdered diet mix, which was immensely profitable. Economic losses caused in part by conflicts with his business partners led to his eviction from his home in 1992. Gregory remained active, however, and in 1996 returned to the stage in his critically acclaimed one-man show, Dick Gregory Live! The reviews of Gregory’s show compared him to the greatest stand-ups in the history of Broadway

“Judge Me Gently”: Reflections on the Religious Life of John Milton Gregory, 1822–1898
No full text John Milton Gregory is familiar to many Christian educators through his 19th-century publication, The Seven Laws of Teaching. For most readers of this important book, little is known about the author himself. This article explores the religious life and theological foundations of John Milton Gregory, who was both author of The Seven Laws of Teaching and founding president of the University of Illinois. Utilizing his spiritual diaries preserved in his daughter's biography of her father and archival sources from the University of Illinois, this essay offers a theological and spiritual understanding of this important historical figure. </jats:p
