Automatic Translation of FORTRAN Programs to Vector Form

by Randy Allen, Ken Kennedy - ACM Transactions on Programming Languages and Systems , 1987
"... This paper discusses the theoretical concepts underlying a project at Rice University to develop an automatic translator, called PFC (for Parallel FORTRAN Converter), from FORTRAN to FORTRAN 8x. The Rice project, based initially upon the research of Kuck and others at the University of Illinois [6, ..."

The LRPD Test: Speculative Run-Time Parallelization of Loops with Privatization and Reduction Parallelization

by Lawrence Rauchwerger, David Padua , 1995
"... Current parallelizing compilers cannot identify a significant fraction of parallelizable loops because they have complex or statically insufficiently defined access patterns. As parallelizable loops arise frequently in practice, we advocate a novel framework for their identification: speculatively e ..."

pattern matching: it detects at run--time if the values stored in an array participate in a reduction operation, even if they are transferred through private variables and/or are affected by statically unpredictable control flow. We present experimental results on loops from the PERFECT Benchmarks which

Self-determination and persistence in a real-life setting: Toward a motivational model of high school dropout.

by Robert J Vallerand , Michelle S Fbrtier , Frederic Guay - Journal of Personality and Social Psychology, , 1997
"... The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the so ..."

This model posits that teachers', parents', and the school administration's autonomy-supportive behaviors toward students influence their perceptions of competence and autonomy. The less autonomy supportive (or the more controlling

Definitional Trees

by Sergio Antoy - In Proc. of the 3rd International Conference on Algebraic and Logic Programming , 1992
"... . Rewriting is a computational paradigm that specifies the actions, but not the control. We introduce a hierarchical structure representing, at a high level of abstraction, a form of control. Its application solves a specific problem arising in the design and implementation of inherently sequential, ..."

necessary set of redexes are related by an and-or relation. Both concepts find application in parallel implementations of rewriting. In an environment in which computations can be executed in parallel we are able to detect sequential computations in order to minimize overheads and/or optimize execution

INCENTIVES FOR POLLUTION CONTROL: REGULATION AND(?) OR(?) INFORMATION by

by Jérôme Foulon A, Paul Lanoie A, Benoît Laplante B
"... The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the World Bank, its Executive Directors, or the countries they represent. Executive Summary An increasing number of regulators have adopted public ..."

Previous empirical analyses on monitoring and enforcement issues have focused their attention strictly on studying the impact of the traditional monitoring (inspections) and enforcement (fines and penalties) practices on the environmental

The Multiscalar Architecture

by Manoj Franklin , 1993
"... The centerpiece of this thesis is a new processing paradigm for exploiting instruction level parallelism. This paradigm, called the multiscalar paradigm, splits the program into many smaller tasks, and exploits fine-grain parallelism by executing multiple, possibly (control and/or data) depen-dent t ..."

Longer-term effects of Head Start

by Eliana Garces , Duncan Thomas , Janet Currie Ucla , Nber - American Economic Review , 2002
"... Abstract Public early intervention programs like Head Start are often justified as investments in children. Yet nothing is known about the long-term effects of Head Start. This paper draws on unique data from the Panel Study of Income Dynamics to provide new evidence on the effects of Head Start on ..."

stretches back over a quarter century, we are able to control for family background and the environment in which each respondent grew up in great detail. Third, the PSID provides a nationally representative sample of children who participated in actual Head Start programs rather than experimental model

Materials for an exploratory theory of the network society.

"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

Software Tamper Resistance: Obstructing Static Analysis of Programs

by Chenxi Wang, Jonathan Hill, John Knight, Jack Davidson , 2000
"... In this paper we address the problem of protecting trusted software on untrusted hosts by code obfuscation. We address one aspect of the problem, namely obstructing static analysis of programs. The presence of aliases has been proven to restrict greatly the precision of static data-flow analysis. M ..."

flow information very slowly and/or with little precision. We describe a set of transformations that introduce aliases and further hinder the analysis by a systematic "break-down" of the program control-flow; transforming high level control transfers to indirect addressing through aliased

Continuity and discontinuity of behavioral inhibition and exuberance: Psychophysiological and behavioral influences across the first four years of life.

by Nathan A Fox , Heather A Henderson , Kenneth H Rubin , Susan D Calkins , Louis A Schmidt Fox , N Henderson , H Rubin , K Calkins , S D & Schmidt , L - Child Development, , 2001
"... Abstract: Four-month-old infants were screened (N = 433) for temperamental patterns thought to predict behavioral inhibition, including motor reactivity and the expression of negative affect. Those selected (N = 153) were assessed at multiple age points across the first 4 years of life for behavior ..."

from all channels of the EEG record prior to subsequent analysis. The re-referenced, artifact-scored EEG data were submitted to a discrete Fourier transform analysis that utilized a Hanning window with 50% overlap. The result of this analysis was to produce power in picowatt ohms (or microvolts squared
