Examining the Potential Exploitation of UNOS Policies

The United Network for Organ Sharing (UNOS) waiting list was designed as a just and equitable system through which the limited number of organs is allocated to the millions of Americans in need of a transplant. People have trusted the system because of the belief that everyone on the list has an equal opportunity to receive an organ and also that allocation is blind to matters of financial standing, celebrity or political power. Recent events have revealed that certain practices and policies have the potential to be exploited. The policies addressed in this paper enable those on the list with the proper resources to gain an advantage over other less fortunate members, creating a system that benefits not the individual most in medical need, but the one with the best resources. These policies are not only unethical but threaten the balance and success of the entire UNOS system. This paper proposes one possible solution, which seeks to balance the concepts of justice and utility.

     

认知与情绪过程的脑诱发电位研究——情绪的适应性假说

本研究观测了30名女性被试在月经周期中的不同激素时相对图像刺激的情绪价值的主观评估和脑诱发电位反应。调节刺激的情绪价值的五类幻灯片分别为普通人像、婴儿像、皮肤病人像、男模特儿像和女模特儿像。实验发现只有脑诱发电位的P3成份随刺激的情绪价值和激素的时相而变化。被评为喜爱与不喜爱的图像(婴儿像和皮肤病人像)所诱发的P3波在幅度上均明显高于中性图像(普通人像)所致的P3反应。在高孕激素时相,对婴儿像和男模特儿像的P3反应高于在低孕激素时相对同类刺激的P3反应。高孕激素时相还伴有对各类图像性感程度评估值的降低。对各类图像喜爱程度的评估则随雌激素水平的上升而增高。上述实验结果表明,P3波敏感于刺激的情绪价值并反映了认知与情绪过程中受生理状态调节的适应性变化。     

Mirror neurons: their implications for group psychotherapy

Recently discovered mirror neurons in the motor cortex of the brain register the actions and intentions of both the organism and others in the environment. As such, they may play a significant role in social behavior and groups. This paper considers the potential implications of mirror neurons and related neural networks for group therapists, proposing that mirror neurons and mirror systems provide "hard-wired" support for the group therapist's belief in the centrality of relationships in the treatment process and exploring their value in accounting for group-as-a-whole phenomena. Mirror neurons further confirm the holistic, social nature of perception, action, and intention as distinct from a stimulus-response behaviorism. The implications of mirror neurons and mirroring processes for the group therapist role, interventions, and training are also discussed.     

Retention of Hispanic/Latino students in first grade: Child, parent, teacher, school, and peer predictors

A sample of 283 Hispanic children with literacy performance at entrance to first grade below the median for their school district was studied as part of a larger research project on the predictors of grade retention in grade 1. Following retention decisions, 51 Hispanic students were retained in first grade. Low literacy skills, being young at entrance to first grade, low ego resilience, low support in the teacher-student relationship, and parents' low sense of responsibility for their children's educational outcomes predicted retention decisions. Hierarchical logistics regression investigated the contribution of six categories of variables (academic competencies; socio-demographic characteristics; social, emotional, and behavioral adjustment; resiliency, school context; and home environment) to retention. Controlling for literacy, only being young for grade and parents' low sense of responsibility for their children's adjustment to school made a direct contribution to retention. Early literacy skills were higher for children enrolled in bilingual classrooms than for children in non-bilingual classrooms. Implications for educational policy are discussed.

A Trajectory Approach to Causality

In this paper we propose a new approach to address the ramification problem in common-sense reasoning about action and change. We contrast the methods of McCain and Turner, Thielscher and Sandewall and, based on some of the limitations they encounter, we introduce a trajectory-based approach which keeps a history of the states through which a system evolves to characterise its dynamical state. We furnish an underlying state-transition semantics and a logic that admits an expressive, dynamical account of some typical scenarios which encounter modelling difficulties in the other approaches mentioned.
