Intake, digestibility, and passage of a commercially designed diet by two Propithecus species.

The digestibility and passage of an experimental diet was used to compare the digestive physiology of two Propithecus species: P. verreauxi and P. tattersalli. Though both animals have a similar feeding ecology, the captive status of P. verreauxi is considered more stable than that of P. tattersalli. The test diet included a local tree species, Rhus copallina, at 15% of dry matter intake (DMI) and Mazuri Leafeater Primate Diet at 85% of DMI. The chemical composition of the diet (dry matter basis) was 25% crude protein, 34% neutral detergent fiber (NDF), and 22% acid detergent fiber (ADF) with a gross energy of 4.52 kcal/g. After a 6 week acclimation to the experimental diet, animals were placed in research caging. After a 7 day adjustment period, animals were dosed with chromium mordant and Co-EDTA as markers for digesta passage and all feed refusals and feces were collected at timed intervals for 7 days. Digestibility values, similar for both species, were approximately 65% for dry matter, crude protein, and energy, and 40% and 35% respectively, for NDF and ADF. Transit times (17-18.5 hr) and mean retention times (31-34 hr) were not significantly different between species, and there was no difference between the chromium mordant and Co-EDTA. Serum values for glucose, urea, and non-esterified fatty acids (NEFA) were obtained during four different time periods to monitor nutritional status. While there was no change in serum glucose, serum urea increased over time. The NEFAs increased across all four time periods for P. verreauxi and increased for the first three periods then decreased in the last period for P. tattersalli. Results obtained indicate no difference in digestibility nor digesta passage between species, and that both Propithecus species were similar to other post-gastric folivores.

Digestion of copepod eggs by larval turbot Scophthalmus maximus and egg viability following gut passage

Between 20.5 and 93.6 % of the subitaneous eggs of 6 species of egg-carrying copepods passed undigested through the digestive tracts of larval and early postlarval turbot Scophthalmus maximus. Viability of the eggs of Eurytemora affinis, E. velox and Euterpina acutifrons remained high on egestion (67.0 to 91.7 %), Pseudocalanus elongatus and Oncaea venusta eggs had low viability (1.1 to 1.5 %), while all Corycaeus anglicus eggs were rendered inviable. The indigestibility of the eggs denies the turbot larvae a potentially valuable food resource, while retention of high egg viability in certain species reduces the effect of predation.

Merely Birds of Passage: Lady Hariot Dufferin's Travel Writings and Medical Work in India, 1884-88

This article examines the travel writings and medical work in India of Lady Hariot Dufferin, Vicereine of India between 1884 and 1888. Lady Dufferin accompanied her husband, the Viceroy Lord Dufferin, through various social and political engagements in India, and carved her own niche in colonial and postcolonial history as a pioneer in the medical training of women in India. The article examines her travel writings on India and explores the nature of her complicity in the Raj, as well as the gendered nature of the separate public role she created for herself in relation to her 'zenana work' in providing medical care for the women of India. The author suggests that, through her work, Lady Dufferin challenges and extends the theoretical paradigms of postcolonialist and feminist critiques of empire.

Reentry as a Rite of Passage

Mary Douglas argues that, ‘There are some things we cannot experience without ritual.’ Ex-prisoner reintegration may be one of them. The punishment process involves an inordinate amount of ritual behavior, from the drama of the courtroom to the elaborate de-individuation processes involved in institutionalization. Durkheim argues that these rituals served a distinct purpose for society: engendering social solidarity and shaping penal sensibilities. Like the commission of a crime, the reintegration of the former outcast back into society represents a challenge to the moral order, a delicate transition fraught with danger and possibility. However, unlike punishment, reintegration is not a process characterized by well-orchestrated and familiar rituals. This lack might explain the failings of prisoner reentry in contemporary society. This article reviews the sociological and anthropological literature on rituals, explaining what they are and what they do, focusing in particular on the role of status degradation ceremonies in criminal justice work. Drawing on this literature, the core elements that would be needed to develop rituals of reintegration powerful enough to counteract these degradation effects are discussed, and the potential impact of such hypothetical rituals is explored.
