Issues of Validity in Openly Ideological Research: Between a rock and a soft place

by Patti Lather - Interchange , 1986
"... In this paper, I attempt to reconceptualize validity within the context of openly ideological research. ~ The usefulness of this reconceptualization is tested by apply-ing it to examples from three explicitly value-based research programs: feminist research, neo-Marxist critical ethnography, and Fre ..."

Accelerating Volume Animation by Space-Leaping

by Roni Yagel, Zhouhong Shi , 1993
"... f i In this paper we present a method for speeding the process of volume rendering a sequence o mages. Speedup is based on exploiting coherency between consecutive images to shorten the n path rays take through the volume. This is achieved by providing each ray with information eeded to leap over th ..."

change in the viewing parameters, the C-buffer i ransformed accordingly. In the case of rotation the transformed C-buffer goes through a pro- - b cess of eliminating coordinates that possibly became hidden. The remaining values in the C uffer serve as an estimate of the point where the new rays should

Convertible debt issuance, capital structure change and leverage-related information: Some new evidence, Unpublished manuscript (Amos Tuck School of Business

by Larry Y. Dann, Wayne H. Mikkelson , 1982
"... This paper provides evidence on the valuation effects of convertible debt issuance. Common stockholders earn significant negative abnormal returns at the initial announcement of a convert-ible debt offering, and also at the issuance date. In contrast, the average valuation effect on common stock at ..."

at the announcement of non-convertible debt offerings is only marginally negative, and is zero at issuance. The significant negative average ffect on common stock value appears not to be systematically related to either the degree of leverage change induced by the convertible debt issuance or the extent to which

DNA and its counterions: a molecular dynamics study

by Krystyna Zakrzewska - Nucleic Acids Res , 2004
"... The behaviour of mobile counterions, Na+ and K+, was analysed around a B-DNA double helix with the sequence CCATGCGCTGAC in aqueous solution dur-ing two 50 ns long molecular dynamics trajectories. The movement of both monovalent ions remains dif-fusive in the presence of DNA. Ions sample the com-ple ..."

Differential involvement of parietal and precentral regions in movement preparation and motor intention

by Daniel Thoenissen, Karl Zilles, Ivan Toni - J. Neurosci , 2002
"... Flexible goal-oriented behavior relies on spatial coordinate transformations and motor control mechanisms, but also on the capability to take advantage of contextual information for steer-ing the sensorimotor machinery. Although accurate perfor-mance of a sensorimotor task requires parietal and fron ..."

Eat or be eaten: a theory of mergers and merger waves, Working paper

by Gary Gorton, Matthias Kahl, Richard Rosen , 2005
"... In this paper, we present a model of defensive mergers and merger waves. We argue that mergers and merger waves can occur when managers prefer that their firms remain independent rather than be acquired. We assume that managers can reduce their chance of being acquired by acquir-ing another firm and ..."

COMPASS: A Probabilistic Indoor Positioning System Based on 802.11

by Thomas King, Stephan Kopf, Thomas Haenselmann, Christian Lubberger, Wolfgang Effelsberg - and Digital Compasses”, in Proc. The First International Workshop on Wireless Network Testbeds, Experimental Evaluation & Characterization(WiNTECH ’06 , 2006
"... Positioning systems are one of the key elements required by location-based services. This paper presents the design, implemen-tation and analysis of a positioning system called COMPASS which is based on 802.11-compliant network infrastructure and digital compasses. On the mobile device, COMPASS samp ..."

The remaining training data is used by a proba-bilistic positioning algorithm to determine the position of the user. While prior

How do people know

by Deanna Kuhn - Psychological Science , 2001
"... To fully understand processes of knowing and knowledge acquisition, it is necessary to examine people’s understanding of their own know-ing. Individual and developmental differences in what it means to know something, and hence in the criteria for justifying knowledge claims, have potentially wide-r ..."

Saliency estimation using a non-parametric low-level vision model

by Naila Murray, Maria Vanrell, Xavier Otazu, C. Alej, Ro Parraga - CVPR
"... Many successful models for predicting attention in a scene involve three main steps: convolution with a set of filters, a center-surround mechanism and spatial pooling to construct a saliency map. However, integrating spatial information and justifying the choice of various parame-ter values remain ..."

Particle Physics

The resulting motion is physi ..."
