Non-native invasive plant species (NNIPS) pose a serious socio-ecological challenge due to their potential to replace and damage critical human-sustaining ecosystems (OTA 1993 ; Mack et al. 2000 ; Pimentel 2002 ) . The impacts of non-native species are widespread and signi fi cant—altering ecosystem structure and function, threatening other species, and imposing human economic and cultural cost...

American distress at the horrors produced by the atomic bombs released on Hiroshima and Nagasaki in 1945 generated a laudable desire to salvage something positive from the damage. Immediately after the war, the American government sent survey teams to the bombed cities to evaluate the extent and nature of the damage. An account of those early days has appeared in The Yale Journal [ 1,2]. The re...

Post-war planning is the theme of practically all recent engineering meetings. This Thirtieth Annual Purdue Road School is no exception. You have already heard some interesting discussions on highway post­ war planning. Other papers will be presented at the following ses­ sions dealing with this very timely subject. Engineers are generally agreed that considerable thought should be given to thi...

Road accidents claim a staggeringly high number of lives every year. From drunk driving, rash driving and driver distraction to visual impairment, over speeding and over-crowding of vehicles, the majority of road accidents occur because of some fault or the other of the driver/occupants of the vehicle. According to the report on “Road Accidents in India, 2011” by the Ministry of Transport and H...

Agents form expectations about the future in many markets, and these expectations drive investment and consumption behavior, inform entry and exit choices, and can even provide direct satisfaction or distress. How agents form expectations is therefore of central interest to economists. This paper reviews several competing theories and then provides empirical evidence about what elements make up...

ECOSYSTEMS escalate daily with each tree felled, road built deeper into the forest, and additional human to feed, shelter and clothe, with ever dwindling natural resources. Biologists working in the field of tropical conservation are familiar with the increasingly complex and pervasive anthropogenic changes, negatively impacting the world, and challenging conservation efforts. These human-induc...

Guilt has been identified as both an intrapsychic and an interpersonal emotion. The current study presents evidence of the existence of two senses of guilt, deontological and altruistic guilt, induced through different experimental paradigms. Deontological guilt evolves from having slighted moral authority or norms, while altruistic guilt arises from selfish behavior and the distress of others....

Emotion is a cognitive mechanism that directs an agent’s thoughts and attention to what is relevant, important, and significant. Such a mechanism is crucial for the design of resource-bounded agents that must operate in highly-dynamic, semi-predictable environments and which need mechanisms for allocating their computational resources efficiently. The aim of this work is to propose a logical an...

The age of retirement is currently an issue of public concern. Never before have the social and economical costs of retirement given rise to so much debate. Advances in medical care, together with changes in lifestyle and working conditions have considerably increased the lifespan of people in the industrial world. As the population ages, the possibility of retiring early in life has become com...
