Selective Breeding For 50 Khz Ultrasonic Vocalization Emission Produces, Howard Cromwell Dec 2011

Selective Breeding For 50 Khz Ultrasonic Vocalization Emission Produces, Howard Cromwell

Howard Casey Cromwell

Ultrasonic vocalizations (USVs) are emitted by rodents and can signal either negative or positive affective states in social and nonsocial contexts. Our recent work has utilized selective breeding based upon the emission of 50 kHz USVs in response to standard cross species hand play—namely experimenters ‘tickling’ rats. Previous work has shown that high-tickle responsive animals (i.e., rats emitting abundant 50 kHz USVs) are gregarious and express enhanced positive emotional behaviors relative to animals exhibiting low 50 kHz USVs. The present study extends this work by examining the developmental profile of play behavior and the suppression of play behavior by predator …

Smart Development: Saudi Arabia's Quest For A Knowledge Economy, Giulio M. Gallarotti, Isam Yahia Al Filali

Giulio M Gallarotti

Nations that have sought to overcome the resource curse and other barriers to economic growth have for some time sought greater development through a number of strategies: from import substitution in the 1950s to current strategies based on microfinance and human-capabilities approaches. Needless to say, the international community is still searching for the elusive Holy Grail of the optimal development strategy. One strategy that is gaining greater attention and adherents is that of promoting a transition to a knowledge economy. This paper is about one such nation: Saudi Arabia. In analyzing the Kingdom’s quest for a knowledge economy, this article …


The Distributional Effects Of Nafta In Mexico, Kathy Baylis, Rafael Garduno-Rivera, Gianfranco Piras Dec 2011

The Distributional Effects Of Nafta In Mexico, Kathy Baylis, Rafael Garduno-Rivera, Gianfranco Piras

Kathy Baylis

This paper studies the regional distribution of benefits from trade in Mexico after the North American Free Trade Agreement (NAFTA). Specifically, we ask whether or not NAFTA increased the concentration of economic activity in Mexico. Unlike previous work which uses state-level data, we identify the effect of NAFTA on economic activity at the municipal level allowing us to observe detailed growth patterns across space. To explicitly identify the effect of the trade agreement, we contrast changes in economic activity in regions and sectors more and less likely to be affected by trade. Given the spatial nature of these data, we …
