We investigate whether one can determine from the transcripts of U.S. Congressional floor debates whether the speeches represent support of or opposition to proposed legislation. To address this problem, we exploit the fact that these speeches occur as part of a discussion; this allows us to use sources of information regarding relationships between(More)
Autosomal ancestry informative markers (AIMs) are useful for inferring individual biogeographical ancestry (I-BGA) and admixture. Ancestry estimates obtained from Y and mtDNA are useful for reconstructing population expansions and migrations in our recent past but individual genomic admixture estimates are useful to test for association of admixture with(More)
BACKGROUND The incidence of empyema increased dramatically in children during the 1990s and early 2000s. We investigated the relationship between changes in the incidence of childhood empyema in Scotland following the 2006 introduction of routine heptavalent conjugate pneumococcal vaccination (PCv-7) and the 2010 introduction of the 13-valent (PCV-13)(More)
networking technology, Digital has built an Internet Protocol version 6 (IPv6) prototype for the Digital UNIX operating system. In this paper, we describe the design of the Digital UNIX IPv6 prototype and its history relevant to the Internet Protocol next generation (IPng) effort in the Internet Engineering Task Force (IETF). We also compare its(More)
Studies of interactions between invasive and native species often focus on impacts on natives. We report potential impacts of a native predator, the Lake Erie Watersnake (Nerodia sipdeon insularum) on an invasive fish, the Round Goby (Apollonia melanostomus). Round Gobies have increased exponentially in the Great Lakes and now constitute >90% of prey(More)
This paper reports current findings from a multi-phased research project that is an offshoot of a 3-year, $155,000 ‘‘Best Practices in the Use of Technology’’ grant awarded to one of the co-authors, 1998–2001. The expanded Phase 1 portion of the study has a general focus on the cognitive complexity of student written responses over time in Virtual(More)
The quality and duration of control in two groups of parkinsonian patients under treatment with an L-dopa-based drug alone or L-dopa-based drug which has been partially substituted with bromocriptine are being compared over a 5-year period using a double-blind placebo-controlled study design. The aim is to establish whether early addition of bromocriptine(More)
OBJECTIVES To report a novel method of accomplishing laparoscopic lower pole partial nephrectomy in an acute porcine model using a bipolar needle electrode without the need for renal arterial occlusion. METHODS Six animals (12 renal units) underwent laparoscopic polar nephrectomy using the bipolar needle electrode. After complete laparoscopic mobilization(More)
One of the most common questions asked by researchers across a variety of scientific disciplines is ‘How does the number of nodes connected together into a network influence the efficiency and reliability of that network?’. While social scientists and epidemiologists might think of ‘nodes’ and ‘connections’ as people interacting within a social network,(More)
