Black hole critical collapse in infinite dimensions: continuous self-similar solutions
No full textAbstract We investigate the dynamics of black hole critical collapse in the limit of a large number of spacetime dimensions, D. In particular, we study the spherical gravitational collapse of a massless, scale-invariant scalar field with continuous self-similarity (CSS). The large number of dimensions provides a natural separation of scales, simplifying the equations of motion at each scale where different effects dominate. With this approximation scheme, we construct matched asymptotic solutions for this family, including the critical solution. We then compute the mass critical exponent of the black hole for linear perturbations that break CSS, finding that it asymptotes to a constant value in infinite dimensions. Additionally, we present a link between these solutions and closed Friedmann-Lemaître-Robertson-Walker (FLRW) cosmologies with a dimension-dependent equation of state and cosmological constant. The critical solution corresponds to an unstable Einstein-like universe, while subcritical and supercritical solutions correspond to bouncing and crunching cosmologies respectively. Our results provide a proof of concept for the large-D expansion as a powerful analytic tool in gravitational collapse and suggest potential extensions to other self-similar systems
Isaac R. Clark Memorial Collection
No full textDr. Isaac Rufus Clark (1925-1990), the son of Reverend James H. and Lillian Clark was born February 15, 1925 in New Castle, Pennsylvania. He received his Bachelor of Arts degree from Wilberforce University in 1951, and in 1952, he received his Bachelor of Divinity degree from Payne Theological Seminary. Dr. Clark went on to receive his Ph.D. in Theology from Boston University in 1958. Clark was a lifelong member of the African Methodist Episcopal Church. He made public his call to the ministry in 1946, and in 1952 he was ordained as an elder.In 1962, Dr. Clark joined the faculty at the Interdenominational Theological Center as Professor of Homiletics and Director of Field Education. In recognition of his contributions as a professor and scholar, in 1975 he was chosen to be the first Fuller E. Callaway Professor of Homiletics at the Interdenominational Theological Center which he held until his death at the age of 64.

Feminist Readings on Abu Ghraib: Introduction
No full textThe author introduces three articles published in this issue. The articles were written by Melanie Richter-Montpetit, Liz Philipose and Laura Sjoberg. Each discusses the atrocities committed by U.S. military personnel at Abu Ghraib prison in Iraq in 2003 and 2004. The events are examined in the context of the photographs taken by U.S. Army Reserve guards and the global commentary that was generated to explain those photographs, especially those of U.S. Army Reserve clerk Lynndie R. England
Density-dependent interactions within a complex life cycle: the roles of cohort structure and mode of recruitment
No full textAnalysed the effects of cohort structure, density, egg hatch inhibition and cannibalism on estimated per capita growth rate (r′) in populations of Aedes triseriatus established in artificial habitats. As density increased from 0.5 K to 0.75 K to the estimated carrying capacity (K = 60 larvae per 100 ml), r′ decreased, along with other measures of success: survivorship, female size, and development rate. Cohort structure and recruitment schedule significantly influenced r′. Populations initiated as eggs achieved r′ values greater than cohorts started as first instar larvae and substantially greater than those populations consisting of single cohorts. There was no evidence for cannibalism in the experimental habitats, which were stocked with leaf detritus and treehole water. Egg-initiated cohorts exhibited the greatest developmental asynchrony during the first month of the experiment, whereas cohorts added as 2-day-old larvae displayed highly synchronized development. Increased competitive interactions in this latter treatment may explain the small size attained by adult females emerging from these populations. Differences among multiple cohort groups increased with increasing density. Results emphasize the need to incorporate overlapping stages into experimental designs for populations that develop asynchronously, and the value of using r′ as a descriptor of success rather than the individual components of success (eg survivorship, size, and development rate) which can lead to misinterpretations of productivity. -from Author

Toward a clear and inclusive conceptualization of parental control: Reply to the commentaries
No full textIn response to J. E. . Grusec\u27s (2009) commentary in this issue, we argue that the conceptualization of control we present in our article is inclusive of multiple forms of control, including those she suggests our definition excludes. We also make the case in response to R. D. . Conger\u27s (2009) commentary that structure and control are distinct dimensions of parenting that should not be combined linearly as he recommends. © 2009, Copyright the Author(s).
