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

, & Curtis, 1979) reveals that children's perceptions of adults in authority positions are quite accurate and in fact more accurate than adults' reports of their own behaviors. We therefore feel that our strategy was appropriate. 2 That some of the scales used in this study yielded alphas
Design Tradeoffs in Implementing Real-Time Channels on Bus-Based Multiprocessor Hosts
, 1995
"... There are a growing number of real-time applications (e.g., real-time controls, and audio/video conferencing) that require certain quality-of-service (QoS) from the underlying communication subsystem. The communication subsystem must support real-time communication services that can be used to provi ..."

to provide the required QoS of these applications, while providing reasonably good performance for best-effort traffic. In this paper we explore the design tradeoffs involved in supporting real-time communication on bus-based multiprocessor hosts using standard network hardware. These tradeoffs are examined
Indicators for Social and Economic Coping Capacity - Moving Toward a Working Definition of Adaptive Capacity”, Wesleyan-CMU Working Paper.
, 2001
"... Abstract This paper offers a practically motivated method for evaluating systems' abilities to handle external stress. The method is designed to assess the potential contributions of various adaptation options to improving systems' coping capacities by focusing attention directly on the u ..."

Each factor inserted into equation The ability of adaptation option (j) to, in fact, influence a system's exposure or sensitivity to an external stress can meanwhile be reflected
Challenging the trade-off model for the evolution of virulence: is virulence management feasible?
- Trends Microbiol.
, 2003
"... Progress in understanding the evolution of infectious diseases has inspired proposals to manage the evolution of pathogen (including parasite) virulence. A common view is that social interventions that lower pathogen transmission will indirectly select lower virulence because of a trade-off between ..."

of the pathogenic form, and relaxation of vaccine coverage has led to subsequent increases Why the difficulty? The trade-off model is based on two assumptions: (1) parasite-induced host mortality is costly for the parasite; and (2) transmission and virulence are inextricably coupled. Although these assumptions do
J2EE Performance and Scalability- From Measuring to Predicting
"... Abstract — J2EE applications are becoming increasingly ubiquitous and with their increasing adoption, performance and scalability issues are gaining in importance. For a J2EE application to perform well and be scalable, both the platform on which it is built and the application design must be effici ..."

Analyzing Security and Energy Tradeoffs in Autonomic Capacity Management
"... Abstract—Capacity management of a hosting infrastructure has traditionally focused only on performance goals. However, the quality of service provided to the hosted applications, and ultimately the revenues achieved by the provider, depend also on other aspects, such as security and energy constrain ..."

Throughput-Delay Trade-off in Energy Constrained Wireless Networks
"... The random network model assumed in this paper is a generalization of the model in [1] that incorporates transmission energy consumption. We assume a random network of n nodes distributed uniformly at random on a unit torus with each node having a randomly chosen node as its destination. We assume t ..."

(n), is the average energy-per-bit required to communicate between an S-D pair, averaged over all n S-D pairs, and all random network configurations. In this model, the throughput, delay and energy-per-bit for a communication scheme are related through the scheme’s average transmission range, i.e., average hop
Leveraging Block Decisions and Aggregation in the ShareStreams QoS Architecture
- IN PROCEEDINGS OF THE INTERNATIONAL CONFERENCE OF PARALLEL AND DISTRIBUTED SYSTEMS (IPDPS
, 2003

"... The broad-band 1–300keV Suzaku spectrum of IGR J17497–2821, the X-ray transient discovered by INTEGRAL in September 2006, is presented. Suzaku observed IGR J17497–2821 on September 25, eight days after its discovery, for a net exposure of about 53ksec. During the Suzaku observation, IGR J17497–2821 ..."

–2821 is very bright, 2 × 1037 erg s−1 at 8kpc in the 1–300keV range, and shows a hard spectrum, typical of black hole candidates in the low-hard state. Despite the multi-mission X-ray monitoring of the source, only with Suzaku is it possible to obtain a broad-band spectrum in the 1–300keV range with a very
The Power-Performance Tradeoffs of the Intel Xeon Phi on HPC Applications
"... Abstract—Accelerators are used in about 13 % of the current Top500 List. Supercomputers leveraging accelerators grew by a factor of 2.2x in 2012 and are expected to completely dominate the Top500 by 2015. Though most of these deployments use NVIDIA GPGPU accelerators, Intel’s Xeon Phi architecture w ..."
