Cartography: maps 2.0

Abstract: At 11.35 am PDT on 18 September 2007 at Vandenberg Air Force base in California, DigitalGlobe’s new WorldView-1 satellite launched into orbit. The satellite is capable of collecting imagery over as much as three-quarters of a million square kilometers a day in resolution as fi ne as 0.5 m. A second satellite will be launched in 2008, capable of photographing nearly a million square kilometers daily at the same high resolution. The data are twice the resolution of the pre-vious industry leader, the IKONOS satellite launched in 1999 and close to the military’s own resolution of 10 cm (Monmonier, 2002).What is significant about the launch is not only the extent and resolution of the imagery (which from all vendors now covers over half of the world’s population) but also the fact that this imagery will be available commercially (look for it in Google Earth). Such imagery, alongside the tremendous possibilities of ‘crowdsourced’ geospatial data, represent interesting new develop-ments in cartography.In the fi rst of three reviews assessing the current state of cartography, I focus on the explosion of new ‘spatial media’ on the web. This topic goes under a bewildering number of names including the geospatial web or geoweb (Scharl and Tochtermann, 2007), neogeography (Turner, 2006), locative media (Rheingold, 2002), DigiPlace (Zook and Graham, 2007a), spatial crowdsourcing or geocollaboration (Hopfer and MacEachren, 2007) and map hacking (Erle

Therapeutic alliance in depression treatment: controlling for prior change and patient characteristics.

Abstract: Although many studies report that the therapeutic alliance predicts psychotherapy outcome, few exclude the possibility that this association is accounted for by 3rd variables, such as prior improvement and prognostically relevant patient characteristics. The authors treated 367 chronically depressed patients with the cognitive-behavioral analysis system of psychotherapy (CBASP), alone or with medication. Using mixed effects growth-curve analyses, they found the early alliance significantly predicted subsequent improvement in depressive symptoms after controlling for prior improvement and 8 prognostically relevant patient characteristics. In contrast, neither early level nor change in symptoms predicted the subsequent level or course of the alliance. Patients receiving combination treatment reported stronger alliances with their psychotherapists than patients receiving CBASP alone. However, the impact of the alliance on outcome was similar for both treatment conditions.

Tournament Incentives, Firm Risk, and Corporate Policies

Abstract: This paper tests the proposition that higher tournament incentives will result in greater risk taking by senior managers in order to increase their chance of promotion to the rank of CEO. Measuring tournament incentives as the pay gap between the CEO and the next layer of senior managers, we find a significantly positive relation between firm risk and tournament incentives. Further, we find that greater tournament incentives lead to higher R&D intensity, firm focus, and leverage but lower capital expenditures intensity. Our results support the hypothesis that option-like features of intra-organizational CEO promotion tournaments provide incentives to senior executives to increase firm risk by following riskier policies. Finally, the compensation levels and structures of executives of financial institutions have received a great deal of scrutiny after the financial crisis. In a separate examination of financial firms, we again find a significantly positive relation between firm risk and tournament incentives.

What's the Subject of Study Abroad?: Race, Gender, and "Living Culture"

Abstract: Based on an ethnographic study that focused on the relations of students’ in- and out-of-class cultural learning during a 5-week study abroad program in Spain, this article analyzes processes of teaching and learning in a Spanish culture and civilization class, the experiences of the only African-American student on the program, and students’ responses to a class meeting in which race was overtly problematized. In contrast to the shared construction of cultural knowledge that characterized the class, discussion of race and gender was limited in its complexity, despite signs of new understandings among students. Given a need for all students to gain multiple cultural perspectives and growing evidence that peer groups constitute sources of identity and cross-cultural understanding for students abroad, we suggest that study abroad curricula incorporate sustained discussion of students’ sociocultural differences and resulting particularities in their experiences in the host culture as part of the formal curriculum.

The Effect of Social Experience on Serotonergic Modulation of the Escape Circuit of Crayfish

Abstract: The neuromodulator serotonin has widespread effects in the nervous systems of many animals, often influencing aggression and dominance status. In crayfish, the effect of serotonin on the neural circuit for tailflip escape behavior was found to depend on the animal's social experience. Serotonin reversibly enhanced the response to sensory stimuli of the lateral giant (LG) tailflip command neuron in socially dominant crayfish, reversibly inhibited it in subordinate animals, and persistently enhanced it in socially isolated crayfish. Serotonin receptor agonists had opposing effects: A vertebrate serotonin type 1 receptor agonist inhibited the LG neurons in dominant and subordinate crayfish and had no effect in isolates, whereas a vertebrate serotonin type 2 receptor agonist enhanced the LG neurons' responses in all three types of crayfish. The LG neurons appear to have at least two populations of serotonin receptors that differ in efficacy in dominant, subordinate, and socially isolate crayfish.
