The topology of deformation spaces of Kleinian groups

Let M be a compact, hyperbolizable 3-manifold with nonempty incompressible boundary and let AH(\pi_1(M)) denote the space of (conjugacy classes of) discrete faithful representations of \pi_1(M) into PSL 2 (C). The components of the interior MP(\pi_1(M)) of AH(\pi_1(M)) (as a subset of the appropriate representation variety) are enumerated by the space A(M) of marked homeomorphism types of oriented, compact, irreducible 3-manifolds homotopy equivalent to M. In this paper, we give a topological enumeration of the components of the closure of MP(\pi_1(M)) and hence a conjectural topological enumeration of the components of AH(\pi_1(M)). We do so by characterizing exactly which changes of marked homeomorphism type can occur in the algebraic limit of a sequence of isomorphic freely indecomposable Kleinian groups. We use this enumeration to exhibit manifolds M for which AH(\pi_1(M)) has infinitely many components.Comment: 49 pages, published versio

Near-surface ocean current sensors : problems and performance

When current meters are used to measure mean horizontal currents in surface gravity waves, immunity to the vertical component of flow is important, even though the net vertical flow averages to zero and is normal to the desired horizontal components. A technique is presented for estimating the magnitude of the errors introduced by imperfect rejection of the off-axis flows (cross-talk) from laboratory measurements of the current meter "vertical-cosine-response." The predicted dynamic response is shown to compare favorably with laboratory measurements. The measured steady state vertical-cosine-response functions for several practical current sensors are summarized and used to estimate the magnitude of wave-induced errors in horizontal mean current measurements. A new dye technique for evaluating near-surface current meter performance in waves is shown.Prepared for the Working Con6enence on CURRENT MEASUREMENTS sponsored by the NOAA 0ffice of Ocean Engineering with the Delaware Sea Grant College Program

The Relationship Among Self-Reported Aggression, Locus of Control, Expectancy for Success, and Dream Content

This study examined the relationship between elements of two dream content analysis systems, and between dream content variables and self-report measures. One hundred and five college students from two universities in Virginia completed the following self-report measures: Generalized Expectancy for Success Scale (Fibel & Hale, 1978), Internal Control Index (Duttweiler, 1984), Conflict Tactics Scale (Straus, 1979), Verbal Aggressiveness Scale (Infante & Wigley, 1986), and Brief Symptom Inventory (Derogatis & Spencer, 1982). They recorded any dreams they could remember over the subsequent three weeks in a dream journal. Only the data of participants who reported five or more dreams were included (n = 83). Dream content was analyzed using Hall and Van de Castle\u27s (1966) and Gaillard and Phelippeau\u27s (1977) dream content analysis systems. Hall and Van de Castle\u27s Successful Dream Outcome was significantly correlated with Gaillard and Phelippeau\u27s Active Control. Hall and Van de Castle\u27s Verbal Aggressive Interactions was significantly correlated with Gaillard and Phelippeau\u27s Verbal Aggressiveness and Physical Aggressiveness. Hall and Van de Castle\u27s Physical Aggressive Interactions was significantly correlated with Gaillard and Phelippeau\u27s Physical Aggressiveness. The Verbal Aggressiveness Scale was significantly correlated with Gaillard and Phelippeau\u27s Physical Aggressiveness. Contrary to expectation, other dream content was unrelated to personality measures. Several unanticipated correlations were obtained. There appears to be considerable overlap between some aspects of Hall and Van de Castle\u27s and Gaillard and Phelippeau\u27s systems. The results fail to identify a direct relationship between specific dream content categories and specific personality variables. This relationship may not exist, or may be less direct, involving combinations of dream content variables

Hiberno-English and the teaching of modern and contemporary Irish literature in an EFL context

In this paper, we provide a brief historical, linguistic, and literary guide to Hiberno-English, or Irish English, for teachers of English as a Foreign Language who use literature in their classes. We discuss the historical and social development of this dialect and relate it to the works of such authors as Joyce, Synge and Kennelly. Then we describe certain linguistic and cultural features of it which appear in literary texts and could lead to misinterpretations if they are not taken into account. Finally, we discuss how to use works written in non-standard varieties of English, like Hiberno-English, in the classroom, basing our discussion on an early twentieth century play, The Tinker's Wedding by Synge, and a current novel and film, The Snapper, by Doyle

Imperial Influence On The Postcolonial Indian Army, 1945-1973

The British Indian Army, formed from the old presidency armies of the East India Company in 1895, was one of the pillars upon which Britain’s world empire rested. While much has been written on the colonial and global campaigns fought by the Indian Army as a tool of imperial power, comparatively little has been written about the transition of the army from British to Indian control after the end of the Second World War. While independence meant the transition of the force from imperial rule to that of civilian oversight by India’s new national leadership, the Dominion of India inherited thousands of former colonial soldiers, including two generations of British and Indian officers indoctrinated in military and cultural practices developed in the United Kingdom, in colonial India and across the British Empire. The goal of this paper is to examine the legacy of the British Empire on the narrative, ethos, culture, tactics and strategies employed by the Indian Army after 1945, when the army began to transition from British to Indian rule, up to 1973 when the government of India reinstituted the imperial rank of Field Marshal. While other former imperial officers would continue to serve in the army up to the end of the 20th century, the first thirty years after independence were a formative period in the history of the Indian Army, that saw it fight four major wars and see the final departure of white British officers from its ranks. While it became during this time a truly national army, the years after independence were one in which its legacy as an arm of imperial power was debated, and eventually transformed into a key component of military identity in the post-colonial era

Moored acoustic travel time (ATT) current meters : evolution, performance, and future designs

New laboratory measurements and numeric model studies show the present folded-path ATT current meters are stable and sensitive, but are not well suited for mean flow observations in surface gravity waves. Alternate designs which reduce unwanted wake effects are proposed. ATT flowmeter history, principles of acoustic flow sensors, mean flow near cylinders, and the need for linear flow sensors are reviewed.Prepared for the Office of Naval Research under Contract Number N00014-76-C-0197; NR083-400 to the Woods Hole Oceanographic Institution

Geometric Dilations and Operator Annuli

Fix 1<R. The dilation theory for the quantum annulus, consisting of those invertible Hilbert space operators T such that the norm of T and its inverse are both at most R is determined. The proof technique involves a geometric approach to dilation that applies to other well known dilation theorems. The dilation theory for the quantum annulus is compared, and contrasted, with the dilation theory for other canonical operator annuli.Comment: V2. Corrected the attribution for Theorem 1.2. V3. Corrected the proof of Theorem 1.1(c) plus some minor fixe
