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 ..."

intentions to drop out of high school, which are later implemented, leading to actual dropout behavior. This model was tested with high school students (N = 4,537) by means of a prospective design. Results from analyses of variance and a structural equation modeling analysis (with L1SREL) were found

On the Implementation of Pfair-scheduled Multiprocessor Systems

by Philip L. Holman , 2004
"... The goal of this dissertation is to extend the Pfair scheduling approach in order to enable its efficient implementation on a real-time multiprocessor. At present, Pfair scheduling is the only known means for optimally scheduling recurrent real-time tasks on multiprocessors. In addition, there has b ..."

BPISG: A Batching Heuristic Scheduling Algorithm With Taking Index Parameters for Mapping Independent Tasks on Heterogenous Computing Environment

by Arash Ghorbannia Delavar, Ali Reza, Khalili Boroujeni, Javad Bayrampoor
"... In this paper we consider the problem of allocating independent heterogeneous tasks on grid environment in which A new batching heuristic scheduling algorithm with Taking index parameters will be presented. Reference to tasks compute scheduling, several methods are evaluated. With compare Minmean an ..."

Efficient task replication for fast response times in parallel computation

by Da Wang, Gauri Joshi, Gregory Wornell - In CoNEXT , 2013
"... One typical use case of large-scale distributed computing in data centers is to decompose a computation job into many independent tasks and run them in parallel on different machines, sometimes known as “embarrassingly parallel ” computation. For this type of computation, one challenge is that the t ..."

the machine that finishes first. While task replication reduces response time, it usually increases resource usage. In this work, we propose a theoretical framework to analyze the trade-off between response time and resource usage. We show that, while in general, there is a tension between response time

AIDA: Adaptive Application-Independent Data Aggregation in Wireless Sensor Networks

by Tian He, Brian M. Blum, John A. Stankovic, Tarek Abdelzaher - ACM Transactions on Embedded Computing Systems , 2004
"... Sensor networks, a novel paradigm in distributed wireless communication technology, have been proposed for various applications including military surveillance and environmental monitoring. These systems deploy heterogeneous collections of sensors capable of observing and reporting on various dynami ..."

Such systems suffer bandwidth, energy, and throughput constraints that limit the quantity of information transferred from end-to-end. These factors coupled with unpredictable traffic patterns and dynamic network topologies make the task

Feedback Guided Scheduling for Two-Dimensional Loops

by Oleh Olkhovskyy , 2001
"... The richest sources of parallelism are loops with independent iterations. These iterations can be distributed to different processors, thus significantly decreasing execution time. However, in such situations, we may meet the imbalance problem, which means that some of the processors finish the work ..."

Remembering over the short-term: The case against the standard model.

by James S Nairne - Annual Review of Psychology, , 2002
"... s Abstract Psychologists often assume that short-term storage is synonymous with activation, a mnemonic property that keeps information in an immediately accessible form. Permanent knowledge is activated, as a result of on-line cognitive processing, and an activity trace is established "in&quo ..."

length effect should be eliminated under these conditions: Long words, by definition, are associated with longer presentation durations. This means that one would expect the word length effect to disappear in the absence of rehearsal only when the total presentation time has been equated for short

Distributed Constraint Satisfaction Problems to Model Railway Scheduling Problems

"... Railway Scheduling is considered to be a difficult and time-consuming task. This is due to real railway networks can be modelled as Constraint Satisfaction Problems (CSPs), but they require a huge number of variables and constraints. The general CSP is known to be NP-complete; however, distributed m ..."
