This paper uses trace-driven simulation to study the unfairness properties of Web server scheduling strategies, such as Processor Sharing (PS) and Shortest Remaining Processing Time (SRPT). We use a general-purpose probe-based sampling approach to estimate the mean and variance of the job response time for different job sizes, for arbitrary arrival processes and service time distributions. The ...

Discrimination through algorithmic decision making has received considerable attention recently. Prior work on the topic largely focuses on defining conditions for fairness, but does not define proper measures of algorithmic unfairness. In this paper, we focus on the following practically important question: Given two unfair algorithms, how should we determine which of the two is more unfair? O...

The variance of job sojourn time (or waiting time) is used, either explicitly or implicitly, as an indication of unfairness perhaps for as long as queueing theory exists. In this work we demonstrate that this quantity has a disadvantage as an unfairness metric, since it is not local to the busy period in which it is measured. It therefore may account for job discrepancies which are not relevant...

Existing research indicates that parentification can result in positive and negative outcomes for individuals; however, little is known about the mechanisms that account for the variability. This study tested a theoretical model of the relation between parentification tasks and mental health symptoms, with perceived unfairness and differentiation of self (DoS) as mediators. The results supporte...

In this paper, we examine the roles of forgivingness (i.e., forgiving personality) and anger on victims’ responses to unfair events. Results of our study show that the effect of perceived unfairness severity on one’s behavioral responses is mediated by his/her anger. In addition, forgivingness moderates the relationship between perceived unfairness severity and victim’s revenge behavior, such t...

Evolutionary accounts have difficulty explaining why people cooperate with anonymous strangers they will never meet. Recently models, focusing on emotional processing, have been proposed as a potential explanation, with attention focusing on a dual systems approach based on system 1 (fast, intuitive, automatic, effortless, and emotional) and system 2 (slow, reflective, effortful, proactive and ...

Under the TCP congestion control regime, heterogeneous flows, i.e., flows with different round-trip times (RTTs), that share the same bottleneck link will not attain equal portions of the available bandwidth. In fact, according to the TCP friendly formula [1], the throughput ratio of two flows is inversely proportional to the ratio of their RTTs. It has also been shown that TCP’s unfairness to ...
