The neural processes underlying empathy are a subject of intense interest within the social neurosciences. However, very little is known about how brain empathic responses are modulated by the affective link between individuals. We show here that empathic responses are modulated by learned preferences, a result consistent with economic models of social preferences. We engaged male and female volunteers in an economic game, in which two confederates played fairly or unfairly, and then measured brain activity with functional magnetic resonance imaging while these same volunteers observed the confederates receiving pain. Both sexes exhibited empathy-related activation in pain-related brain areas (fronto-insular and anterior cingulate cortices) towards fair players. However, these empathy-related responses were significantly reduced in males when observing an unfair person receiving pain. This effect was accompanied by increased activation in reward-related areas, correlated with an expressed desire for revenge. We conclude that in men (at least) empathic responses are shaped by valuation of other people's social behaviour, such that they empathize with fair opponents while favouring the physical punishment of unfair opponents, a finding that echoes recent evidence for altruistic punishment.

We postulate that exogenous losses-which are typically regarded as introducing undesirable "noise" that needs to be filtered out or hidden from end points-can be surprisingly beneficial. In this paper we evaluate the effects of exogenous losses on transmission control loops, focusing primarily on efficiency and convergence to fairness properties. By analytically capturing the effects of exogenous losses, we are able to characterize the transient behavior of TCP. Our numerical results suggest that "noise" resulting from exogenous losses should not be filtered out blindly, and that a careful examination of the parameter space leads to better strategies regarding the treatment of exogenous losses inside the network. Specifically, we show that while low levels of exogenous losses do help connections converge to their fair share, higher levels of losses lead to inefficient network utilization. We draw the line between these two cases by determining whether or not it is advantageous to hide, or more interestingly introduce, exogenous losses. Our proposed approach is based on classifying the effects of exogenous losses into long-term and short-term effects. Such classification informs the extent to which we control exogenous losses, so as to operate in an efficient and fair region. We validate our results through simulations.

For a given TCP flow, exogenous losses are those occurring on links other than the flow's bottleneck link. Exogenous losses are typically viewed as introducing undesirable "noise" into TCP's feedback control loop, leading to inefficient network utilization and potentially severe global unfairness. This has prompted much research on mechanisms for hiding such losses from end-points. In this paper, we show through analysis and simulations that low levels of exogenous losses are surprisingly beneficial in that they improve stability and convergence, without sacrificing efficiency. Based on this, we argue that exogenous loss awareness should be taken into account in any AQM design that aims to achieve global fairness. To that end, we propose an exogenous-loss aware Queue Management (XQM) that actively accounts for and leverages exogenous losses. We use an equation based approach to derive the quiescent loss rate for a connection based on the connection's profile and its global fair share. In contrast to other queue management techniques, XQM ensures that a connection sees its quiescent loss rate, not only by complementing already existing exogenous losses, but also by actively hiding exogenous losses, if necessary, to achieve global fairness. We establish the advantages of exogenous-loss awareness using extensive simulations in which, we contrast the performance of XQM to that of a host of traditional exogenous-loss unaware AQM techniques.

This thesis interrogates the construction of fairness to the accused in historic child sexual abuse trials in Ireland. The protection of fairness is a requirement of any trial that claims to adhere to the rule of law. Historic child sexual abuse trials, in which the charges relate to events that are alleged to have taken place decades previously, present serious challenges to the ability of the trial process to safeguard fairness. They are a litmus test of the courts’ commitment to fairness. The thesis finds that in historic abuse trials fairness to the accused has been significantly eroded and that therefore the Irish Courts have failed to respect the core of the rule of law in these most serious of prosecutions. The thesis scrutinises two bodies of case law, both of which deal with the issue of whether evidence should reach the jury. First, it examines the decisions on applications brought by defendants seeking to prohibit their trial. The courts hearing prohibition applications face a dilemma: how to ensure the defendant is not put at risk of an unfair trial, while at the same time recognising that delay in reporting is a defining feature of these cases. The thesis traces the development of the prohibition case law and tracks the shifting interpretations given to fairness by the courts. Second, the thesis examines what fairness means in the superior courts’ decisions regarding the admissibility of the following kinds of evidence, each of which presents particular challenges to the ability of the trial to safeguard fairness: evidence of multiple complainants; evidence of recovered memories and evidence of complainants’ therapeutic records. The thesis finds that in both bodies of case law the Irish courts have hollowed out the meaning of fairness. It makes proposals on how fairness might be placed at the heart of courts’ decisions on admissibility in historic abuse trials. The thesis concludes that the erosion of fairness in historic abuse trials is indicative of a move away from the liberal model of criminal justice. It cautions that unless fairness is prioritised in historic child sexual abuse trials the legitimacy of these trials and that of all Irish criminal trials will be contestable.

This Portfolio of Exploration outlines the course of learning by a practitioner on a personal leadership journey. It constructs a functional examination of ideas around leadership. It explores the belief system which underpins leadership practice and it also explores to what extent the increased participation of women can lead to a qualitatively different type of leadership. Different models of leadership are explored to find the model which can best fit with the author’s perception of leadership. The Women’s Intercultural Leadership Model is discussed. This model conceptualises leadership as the envisioning of oneself and others as potential leaders. It seeks to promote that recognition whilst at the same time encouraging personal transformation. The promotion of a values based leadership is examined. The value of fairness is examined as an element of functional leadership. The extent to which increasing the number of women in leadership can lead to a qualitatively different type of leadership is explored. Drucker’s assertion that every practice rests on theory is used to unearth the underlying assumptions of this reflective practitioner doctorate. Kegan’s Theory of Adult Mental Development and Subject-Object separation is used to explicitly examine knowledge construction. Myers Briggs Type Indicator (MBTI) and Assumption/Commitment/Behaviour/Outcome (ACBO) template are used to promote practice change.

This article stems from setting student projects. It describes in detail the outcome of a project designed to ascertain the views of the public in relation to ancillary relief and what they consider to be a 'fair' outcome. The rationale for undertaking student projects has been discussed at length in another article and is therefore only alluded to here. The discussion centres around the law, findings and outcome of the project. Students studying the Family Law course at Sheffield University were required to survey members of the public in order to gather their views on the division of assets on divorce and then to analyse the public's response in light of the seminal decision of the House of Lords in White v White [2001] 1 AC 596.

An equation is presented for calculating the fairness of dynamically adaptive packet schedulers such as dynamic weighted fair queuing (DWFQ). The fairness of static packet schedulers such as weighted fair queue (WFQ) can be found using the widely accepted Worst-case Fair Index. The fairness of DWFQ can be measured using an Adapted Worst-case Fairness Index (AWFI). The AWFI enables a direct comparison of fairness properties of the DWFQ or other dynamically adaptive schedulers with static/non-adaptive schedulers.

This paper considers a moral basis for planning theory and endeavours to establish principles of justice which might be relevant to the regulation of development. Whilst the investigation recognises that there is a need for a deeper understanding of the dynamics of governance, it suggests that many of the inefficiencies, inequities and public disquiet concerns relating to planning centre on a drift from a perception that the system is both fair and just, and that practice needs to be anchored on founding values concerned with redistribution and equality. In this context, John Rawls’ theory of justice is employed as a vehicle to capture moral ideas of equality and liberty within a constitutional democracy and as a basis for scrutinising emerging justice based issues which impact upon planning. Using National Policy Statements as a case study, the paper concludes that, whilst there are serious concerns over current policymaking practices, the principles of justice offer a foundation for practical critique which can help overcome problems of mistrust.

The present study examined whether Perceptions of organizational fairness (the procedural and interactional components) were able to diminish the negative effects of high job demands and low job control on the balance between work and family. The study participants were 713 women working in long-term care for elderly people in Finland. The results showed that high job demands, low job control, and unfair decision making were associated with high levels of time-based work interference with family (WIF). Perceptions of organizational fairness were found to partially mediate the association between Job control and WIF In addition, fair treatment and management protected against WIF when demands were low but were unable to bluffer against the negative effects of high job demands.

Multi-threaded processors execute multiple threads concurrently in order to increase overall throughput. It is well documented that multi-threading affects per-thread performance but, more importantly, some threads are affected more than others. This is especially troublesome for multi-programmed workloads. Fairness metrics measure whether all threads are affected equally. However defining equal treatment is not straightforward. Several fairness metrics for multi-threaded processors have been utilized in the literature, although there does not seem to be a consensus on what metric does the best job of measuring fairness. This paper reviews the prevalent fairness metrics and analyzes their main properties. Each metric strikes a different trade-off between fairness in the strict sense and throughput. We categorize the metrics with respect to this property. Based on experimental data for SMT processors, we suggest using the minimum fairness metric in order to balance fairness and throughput.

Public procurement is a potential lever for ensuring greater attention is given to ensuring minimum standards and effective employment rights in the workplace. Public sector purchasers may encourage or require private sector employers from whom they buy to adopt a proactive approach to ensuring fairness at work, focusing on organisational changes that the employer could make. This chapter explores whether and how far public procurement does, or could, influence whether – and how much – employment rights have an impact on employer policy and practice. It considers what public procurement offers as a strategy and what factors help to determine its effectiveness.

In recent years, the US Supreme Court has rather controversially extended the ambit of the Federal Arbitration Act to extend arbitration’s reach into, inter alia¸ consumer matters, with the consequence that consumers are often (and unbeknownst to them) denied remedies which would otherwise be available. Such denied remedies include recourse to class action proceedings, effective denial of punitive damages, access to discovery and the ability to resolve the matter in a convenient forum.

The court’s extension of arbitration’s ambit is controversial. Attempts to overturn this extension have been made in Congress, but to no avail. In contrast to American law, European consumer law looks at pre-dispute agreements to arbitrate directed at consumers with extreme suspicion, and does so on the grounds of fairness. In contrast, some argue that pre-dispute agreements in consumer (and employment) matters are consumer welfare enhancing: they decrease the costs of doing business, which is then passed on to the consumer. This Article examines these latter claims from both an economic and normative perspective.

The economic analysis of these arguments shows that their assumptions do not hold. Rather than being productive of consumer surplus, the use of arbitration is likely to have the opposite effect. The industries from which the recent Supreme Court cases originated not only do not exhibit the industrial structure assumed by the proponents of expanded arbitration, but are also industries which exhibit features that facilitate consumer welfare reducing collusion.

The normative analysis addresses the fairness concerns. It is explicitly based upon John Rawls’ notion of “justice as fairness,” which can provide a lens to evaluate social institutions. This Rawlsian analysis considers the use of extended arbitration in consumer matters in the light of the earlier economic results. It suggests that the asymmetries present in the contractual allocation of rights serve as prima facie evidence that such arbitration–induced exclusions are prima facie unjust/unfair. However, as asymmetry is only a prima facie test, a generalized criticism of the arbitration exclusions (of the sort found in Congress and underlying the European regime) is overbroad.

Group projects form a large and possibly growing component of the work undertaken for assessing students in higher education, and especially in post-graduate work in business. Yet the assessments sources, methods and purposes result in an array of combinations that the literature fails to capture in its full complexity. Tutors may be able to assess the work of the group as well as they might the work of any individual. But grades - and degrees - are awarded to individuals. Writers on higher education speak of using self- and peer-assessment as a way of qualifying the evaluation of group work so as to differentiate between individuals. But these commonly used terms - drawn from approaches to assessing individual work - are ambiguous or even misleading in the context of group work. This paper proposes a framework for discussing the assessment of group projects in an effort to help identify how the benefits of group learning and be translated into fairer summative assessments.
