An Analysis of Short-Term Fairness in Wireless Media Access Protocols
- in Proceedings of ACM Sigmetrics
, 2000
"... We investigate the problem of unfairness over short time scales in decentralized wireless media access (MAC) protocols. Motivated by experimental results over a CSMA/CA-based WaveLAN wireless LAN that shows starvation and degraded TCP performance, we seek to derive a framework for evaluating and ana ..."

and analyzing fairness in the context of distributed MAC protocols. In this paper, we develop two short-term fairness metrics and analyze CSMA/CA, showing quantitatively that while it re- duces collision probabilities via exponential backoff, it is unfair over short time scales even for small population sizes
Reward System for Completing FAQs
"... Abstract. The creation of Answer Communities around a FAQs Site is proposed to speed up the process of answering questions. Our approach combines long-term and short-term rewards. Long-term rewards are found to boost participation, motivating users to complete FAQs with proper answers faster. Keywor ..."

Attention, short-term memory, and action selection: A unifying theory
, 2005
"... Cognitive behaviour requires complex context-dependent processing of information that emerges from the links between attentional perceptual processes, working memory and reward-based evaluation of the performed actions. We describe a computational neuroscience theoretical framework which shows how a ..."

Luigi ZingalesTIME DISCOUNTING FOR PRIMARY AND MONETARY REWARDS *
"... This paper reports a positive and statistically significant relation between short-term discount rates elicited with a monetary and a primary reward (chocolate). The relation is most evident among people who like chocolate and are hungry. This finding suggests that high short-term discount rates are ..."

Long-Term Reward Prediction in TD Models of the Dopamine System
, 2002
"... This article addresses the relationship between long-term reward predictions and slow-timescale neural activity in temporal difference (TD) models of the dopamine system. Such models attempt to explain how the activity of dopamine (DA) neurons relates to errors in the prediction of future rewards. P ..."

. Previous models have been mostly restricted to short-term predictions of rewards expected during a single, somewhat artificially defined trial. Also, the models focused exclusively on the phasic pause-and-burst activity of primate DA neurons; the neurons' slower, tonic background activity was assumed
Extrinsic Rewards: An Adventist Curriculum Perspective for Classroom Management
"... Extrinsic rewards refer to gifts used as a form of motivation for students ’ to attain an academic goal, or given when that particular goal is reached. Though the use of extrinsic rewards have been proven to have some impact on ’ behavior change, such as academic performance, the absence of rewards ..."

Basal ganglia circuits for reward value-guided behavior
"... The basal ganglia are equipped with inhibitory and disinhibitory mechanisms that enable to choose valuable objects and actions. Notably, a value can be determined flexibly by recent experience or stably by prolonged experience. Recent studies have revealed that the head and tail of the caudate nucle ..."

These signals are sent to the superior colliculus through different parts of the substantia nigra, so that the animal looks preferentially at high-valued objects, but in different manners.

Acquiring peekaboo communication: early communication model based on reward prediction
- In Proceedings of the IEEE 6th International Conference on Development and Learning
, 2007
"... Abstract—Infants become sensitive to the regular behavior of their caregivers by the end of 4 months old. In this paper, we propose a communication system for a robot to acquire early communication. The acquisition of the communication is proceeded by the interactions of the three components; the me ..."

Frequency Reward Program This research presents an empirical study of the impact of a retail frequency reward program on store sales. We examine both the “points-pressure, ” or short-term impact, and the “rewarded behavior, ” or long-term impact. The points-pressure impact is due to forward
Short-term gains, long-term pains: How cues about state aid learning in dynamic environments
, 2009
"... Successful investors seeking returns, animals foraging for food, and pilots controlling aircraft all must take into account how their current decisions will impact their future standing. One challenge facing decision makers is that options that appear attractive in the short-term may not turn out be ..."

. We find that perceptual cues that readily align with the underlying state of the task environment help people overcome the impulsive appeal of short-term rewards. Our experimental manipulations, predictions, and analyses are motivated by current work in reinforcement learning which details how
