We are concerned with the control of quality of service (QoS) in wireless cellular networks utilizing linear receivers. We investigate the issues of fairness and total performance, which are measured by a utility function in the form of a weighted sum of link QoS. We disprove the common conjecture on incompatibility of min-max fairness and utility optimality by characterizing network classes in...

Fairness issues within food systems are of increasing concern for policy makers and other stakeholders. Given the topicality relevance fairness systems, there is value in exploring subject further. Simulation modelling has been successfully used to develop test interventions. However, subjectivity intangibleness perceptions make them difficult operationalize a quantitative model. The objective ...

Two experiments were conducted to investigate the impact of fairness on the efficiency of resource allocation decisions. In Experiment 1 participants allocated payoffs to one privileged and one unprivileged group in a multi-stage decision task. Conflicts between fairness and resource preservation were induced. Selfinterest was varied by awarding participants a high or low bonus if a majority of...

Existing research suggests that concerns for fairness may significantly affect the interactions between firms in a distribution channel. We analytically and experimentally evaluate how firms make decisions in a two-stage dyadic channel, in which firms decide on investments in the first stage and then on prices in the second stage. We find that firms’ behavior differs significantly from the pred...

This paper investigates an important channel through which improved access to market information could increase the prices that producers receive from middlemen. I develop a theoretical model of trade between a farmer and a middleman which allows for the existence of different types of middlemen. The source of heterogeneity is attitudes towards fairness. I provide an empirical test of the theor...

While lots of effort is done on behalf of the ATM Forum and the ITU standardisation bodies in specifying the user network interface (UNI) for ATM’s available bit rate (ABR) service the specification of the switch mechanisms will be left to the manufacturers. In this study some of the algorithms proposed for dynamically distributing the available bandwidth at the switches such as EPRCA, CAPC, th...

A number of emerging Internet applications such as videoconferencing and live multimedia broadcasts from Internet TV stations will rely on scheduling algorithms in switches and routers to guarantee performance and an acceptable level of quality of service. Fairness in packet schedulers is an intuitively desirable property with practical value; fair schedulers such as Weighted Fair Queueing are ...

Fair exchange between two or more potentially mutually distrusted parties has been identified as an important issue in electronic commerce. However, the correctness (fairness) of the existing fair exchange protocols that use a Trusted Third Party (TTP) is based on the assumption that during an exchange there are no failures at any of the local systems involved in the exchange, which is too stro...

We argue that different types of managerial controls – mechanisms to direct subordinate’s tasks – increase the salience of particular aspects of fairness among subordinates. In a series of survey and scenario studies, we find that subordinates who perceive market controls engage in distributive fairness monitoring, subordinates who recognize bureaucratic controls engage in procedural fairness m...

the accountability for reasonableness (afr) concept has been developed and discussed for over two decades. its interpretation has been studied in several ways partly guided by the specific settings and the researchers involved. this has again influenced the development of the concept, but not led to universal application. the potential use in health technology assessments (htas) has recently be...
