The authors propose a computational theory of the hippocampal region's function in mediating stimulus representations. The theory assumes that the hippocampal region develops new stimulus representations that enhance the discriminability of differentially predictive cues while compressing the representation of redundant cues. Other brain regions, including cerebral and cerebellar cortices, are ...

The Equal Employment Opportunity Commission (EEOC) has experienced dramatic backlogs of pending charges over the years. In 1977, the backlog reached an all-time high of 130,000 cases pending. Recently, the EEOC announced that the backlog had been reduced to 29,890 cases. A significant portion of this reduction is attributab le to an increased use of mediation. During FY 2001, 7,800 of the 94,59...

This paper presents an econometric mediation analysis. It considers identification of production functions and the sources of output effects (treatment effects) from experimental interventions when some inputs are mismeasured and others are entirely omitted. JEL Code: D24, C21, C43, C38.

China’s elaborate system of local mediation committees has piqued researchers’ curiosity for decades and sparked an argument in these pages. Crucial questions— concerning how much mediation actually takes place, what kinds of disputes are mediated, who seeks mediation, and how successful it is—have gone unanswered for lack of data. This article addresses these issues using original surveys from...

Many college students abandon their goal of completing a degree in science, technology, engineering, or math (STEM) when confronted with challenging introductory-level science courses. In the U.S., this trend is more pronounced for underrepresented minority (URM) and first-generation (FG) students, and contributes to persisting racial and social-class achievement gaps in higher education. Previ...

This paper aims to gain a better understanding of KMS success. Based on the absorptive capacity theory, we develop a research model to explain how the use of KMS increases organizational performance by increasing the organizational absorptive capacity and the higher order capabilities. The absorptive capacity plays an important role in transforming KMS usage into agility and innovativeness and ...

Research adopting self-determination theory (SDT) supports a mediation model whereby coach motivational styles (autonomy support and interpersonal control) predict athletes' engagement and disaffection in youth sport via the satisfaction and frustration of psychological needs (autonomy, competence, and relatedness). Our study extends this research by examining SDT's mediation model longitudinal...

In recent years, mediation analysis has emerged as a powerful tool to disentangle causal pathways from an exposure/treatment to clinically relevant outcomes. Mediation analysis has been applied in scientific fields as diverse as labour market relations and randomized clinical trials of heart disease treatments. In parallel to these applications, the underlying mathematical theory and computer t...
