Quantum and classical complexity in coupled maps

We study a generic and paradigmatic two-degrees-of-freedom system consisting of two coupled perturbed cat maps with different types of dynamics. The Wigner separability entropy (WSE)—equivalent to the operator space entanglement entropy—and the classical separability entropy (CSE) are used as measures of complexity. For the case where both degrees of freedom are hyperbolic, the maps are classically ergodic and the WSE and the CSE behave similarly, growing to higher values than in the doubly elliptic case. However, when one map is elliptic and the other hyperbolic, the WSE reaches the same asymptotic value than that of the doubly hyperbolic case but at a much slower rate. The CSE only follows the WSE for a few map steps, revealing that classical dynamical features are not enough to explain complexity growth.Fil: Bergamasco, Pablo D.. Universidad de Buenos Aires.

Strategies for cost reduction in procuring trucking services

Thesis (M. Eng. in Logistics)--Massachusetts Institute of Technology, Engineering Systems Division, 2009.Includes bibliographical references (leaf 48).This thesis analyzed truckload shipment transactions from 2006 to 2008 in order to compare planned procurement activity to actual procurement activity. The research specifically focused on three costs: Primary, Actual and Market. Primary cost is the cost agreed to pay to the primary carrier and is usually contractually fixed in advance. The actual cost is the cost paid to the carrier that hauls the load and the market cost is the average cost for the lane that a shipper should pay. This market cost is a benchmarking cost available to the shippers. The comparison of planned and actual is important because it helps to develop a strategy that decreases transportation costs by identifying overpaid lanes and carriers and it helps to monitor and make corrective decisions. The research suggests that the matching of planning and execution occurred in less than 10% of the lanes and there are under and overpaid lanes. The execution rendered more than 50% of overpaid lanes and the planning showed a commitment to overpay in 45% or more of lanes. Finally this research proposes ideas to improve the truckload procurement strategy because shippers cannot afford to "plan to waste".by Carlos Gustavo Castro Izaguirre.M.Eng.in Logistic

Two Sides of the Same Coin? The Relations between Prosocial and Physically Aggressive Behaviors

The direct and indirect relations between six types of prosocial behavior and physical aggression were examined. Data were gathered from 252 college students (M age = 21.67 years; 184 women) who completed measures of sympathy, prosocial behavior, and physical aggression. Structural equation modeling revealed that sympathy fully mediated the relations between compliant prosocial behaviors and physical aggression, and partially mediated the relations between altruism and physical aggression and public prosocial behaviors and physical aggression. The fi ndings suggest that the relations between prosocial behaviors and aggression are complex and that prosocial behavior should not be treated as a unitary construct

What Will My Parents Think? Relations Among Adolescents’ Expected Parental Reactions, Prosocial Moral Reasoning, and Prosocial and Antisocial Behaviors

Prior researchers confirmed socialization models depicting parenting practices and social cognitions associated with prosocial and antisocial behaviors. However, little research has focused on processes underlying the link between parenting and these behaviors. Per Grusec and Goodnow’s internalization model, children and adolescents develop expectancies regarding their parents’ reactions to their behaviors. Adolescents’ expected parental reactions to prosocial behaviors were hypothesized to predict prosocial behaviors; expectations regarding antisocial behaviors were expected to predict antisocial behaviors. For this study, 80 adolescents and their parents reported adolescents’ antisocial and prosocial behaviors. Adolescents completed a measure of prosocial moral reasoning and an assessment of how appropriately they expected each parent to react to prosocial and antisocial behaviors. Expected parental reactions to antisocial behavior predicted lower levels of delinquency and aggression (adolescent report). Expected parental reactions to prosocial behavior predicted higher levels of prosocial behavior (adolescent report) and lower levels of delinquency and aggression (mother report)

Religiosity and prosocial behaviours in adolescence: the mediating role of prosocial values

This study examined the hypothesis that religiosity would be differentially related to six types of adolescent prosocial behavior, and that these relations would be mediated by the prosocial value of kindness. Self-report data were collected from 142 high school students (63 per cent female; 91 per cent White; M age = 16.8, S =.80). Religiosity was a significant positive predictor of kindness, as well as compliant, anonymous and altruistic prosocial behavior, but not public, dire and emotional prosocial behavior. Associations between religiosity and both compliant and altruistic prosocial behaviors were mediated by kindness. Direct and indirect paths were found between religiosity and anonymous prosocial behavior. Thus, partial support was found for the mediational hypothesis. Discussion focused on the utility of distinguishing among different types of prosocial behaviors and on the role of religion and values in promoting moral education

Introduction: Moral Development Study in the 21st Century

Questions of right and wrong, good and bad, lawful and unlawful, have been debated by philosophers, theologians, scholars, and ordinary people since ancient times. The moral domain represents humanity\u27s answers to three questions: What is the right thing to do? How is the best state of affairs achieved? What qualities make for a good person? However, the scientific investigation of the moral life has a much shorter intellectual history than does philosophical and religious reflection; nevertheless, it is not new. Moral development theory and research emerged as a critical topic over 100 years ago, at the beginning of the 20th century. Thus, given this deep background, it may surprise readers to learn that this is the very first time that the Nebraska Symposium on Motivation has served as a forum to reflect on what we know about moral development and motivation and to integrate theory and research with practical implications for schools, communities, and childrearing. This book presents the products of the 51st Nebraska Symposium on Motivation: Moral Development through the Life Span: Theory, Research, and Applications. The symposium was held in Lincoln, Nebraska, in April 2003

Identity as a Source of Moral Motivation

Theory and research regarding moral motivation has focused for decades on the roles of moral reasoning and, to some extent, moral emotion. Recently, however, several models of morality have positioned identity as an additional important source of moral motivation. An individual has a moral identity to the extent that he or she has constructed his or her sense of self around moral concerns (e.g., moral values). This paper reviews theory and research linking moral identity to moral behavior and commitment. Additionally, it suggests several key unanswered questions about moral identity and provides recommendations for future research

Evaluation of Iterative DBD Procedures for Bridges

This report addresses the problem of the Displacement Based Evaluation/Design (DBE/D) of reinforced concrete bridges. Throughout the report, the aims and limitations of current seismic evaluation and design practice and the tendencies of the displacement-based seismic evaluation/design are discussed. It presents a state-of-the-art review on the most important results and lessons derived from previous works, and based on them, two evaluation/design methods consistent with the performance-based seismic design philosophy are presentedJRC.G.5-European laboratory for structural assessmen
