This article examines religious practices in the United States, which govern modesty and other dress norms for men. I focus both on the spaces within which they most collide with regulatory regimes of the state and the legal implications of these norms, particularly for observant Muslim men. Undergirding the research are those ‘‘gender equality’’ claims made by many religious adherents, that men are required to maintain proper modesty norms just as are women. Also undergirding the research is the extensive anti-Islam bias in American culture today. The spaces within which men’s religiously proscribed dress and grooming norms are most at issue—indicated by First Amendment legal challenges to rights of religious practice—are primarily those state-controlled, total institutions Goffman describes, such as in the military and prisons. The implications of gendered modesty norms are important, as state control over religious expression in prisons, for example, is much more difficult to contest than in other spaces, although this depends entirely on who is doing the contesting and within which religious context. In American society today—and particularly within the context of growing Islamaphobia following the 9/11 attacks—the implications are greatest for those men practicing ‘‘prison Islam.’’

It is by now a banal observation that published collections of conference papers tend to add up to a whole that is considerably less than the sum of the parts. Nineteenth-Century Geographies, a book that grew out of an interdisciplinary conference held at Rice University in 1998 falls into this category. While assuring my readers that each individual contribution is independently worth a read is likewise a predictable cliché, it is in fact the case that every one of the 17 articles collected here—notwithstanding the rather convoluted Introduction—has much to offer the study, broadly speaking, of ‘cultural spacesof British and American imperialisms in the nineteenth century. . . . All of my complaints aside, this turns out to be a much more enjoyable book to read than to review, and I would recommend skimming and dipping at length. I cannot quite imagine when a read-through of this book might be called for, except perhaps in graduate seminars on related topics.

Gregarine apicomplexans are a diverse group of single-celled parasites that have feeding stages (trophozoites) and gamonts that generally inhabit the extracellular spaces of invertebrate hosts living in marine, freshwater, and terrestrial environments. Inferences about the evolutionary morphology of gregarine apicomplexans are being incrementally refined by molecular phylogenetic data, which suggest that several traits associated with the feeding cells of gregarines arose by convergent evolution. The study reported here supports these inferences by showing how molecular data reveals traits that are phylogenetically misleading within the context of comparative morphology alone. We examined the ultrastructure and molecular phylogenetic positions of two gregarine species isolated from the spaghetti worm Thelepus japonicus: Selenidium terebellae Ray 1930 and S. melongena n. sp. The ultrastructural traits of S. terebellae were very similar to other species of Selenidium sensu stricto, such as having vermiform trophozoites with an apical complex, few epicytic folds, and a dense array of microtubules underlying the trilayered pellicle. By contrast, S. melongena n. sp. lacked a comparably discrete assembly of subpellicular microtubules, instead employing a system of fibrils beneath the cell surface that supported a relatively dense array of helically arranged epicytic folds. Molecular phylogenetic analyses of small subunit rDNA sequences derived from single-cell PCR unexpectedly demonstrated that these two gregarines are close sister species. The ultrastructural differences between these two species were consistent with the fact that S. terebellae infects the inner lining of the host intestines, and S. melongena n. sp. primarily inhabits the coelom, infecting the outside wall of the host intestine. Altogether, these data demonstrate a compelling case of niche partitioning and associated morphological divergence in marine gregarine apicomplexans. (C) 2014 Elsevier GmbH. All rights reserved.

A conjecture by Harder shows a surprising congruence between the coefficients of “classical” modular forms and the Hecke eigenvalues of corresponding Siegel modular forms, contigent upon “large primes” dividing the critical values of the given classical modular form. Harder’s Conjecture has already been verified for one-dimensional spaces of classical and Siegel modular forms (along with some two-dimensional cases), and for primes p 37. We verify the conjecture for higher-dimensional spaces, and up to a comparable prime p.
