Individuals' Rates of Time Preference for Life-Saving Programs in Developing Countries: Results from a Multi-Country Study

Individuals' time preferences for mortality reductions are measured in six Less Developed Countries in Africa, Eastern Europe, and Asia using the contingent valuation method. The results indicate that individuals' discount factors are much lower than those estimated for a United States sample. Also, respondents' intertemporal preferences for saving lives are characterized by a nonexponential discount function. We conclude that the discounting practices currently used in standard economic analyses of development projects are probably poor representations of individuals' actual intertemporal preferences.Time preference

Volume-checking tool

Tool, consisting of a graduated storage vessel and a control panel, can determine the amount of gas entrained by fluid in a closed system, the amount of fluid remaining in a dried system of known volume, or the volume of a container of unknown size

The synthesis of an analogue of the locust CRF-like diuretic peptide, and the biological activities of this and some C-terminal fragments.

The synthesis is described of an analogue of the locust CRF-like diuretic peptide in which methionine in positions 1,3, and 13 is replaced by isosteric methyl-homoserine residues. This analogue has been tested for biological activity on Malpighian tubules in vitro, and feeding behavior in vivo. It is highly active in stimulating fluid secretion and accumulation of cAMP in tubules, and on increasing the latency to feed and reducing meal duration. A 15 residue fragment from the C-terminus of the CRF-like peptide, Locmi-DP32–46, is fully active in the feeding assay, but has only weak ability to stimulate the accumulation of cAMP in tubules. Two smaller fragments, Locmi-DP32–37 and Locmi-DP41–46, were tested but neither had consistent biological activity in any of the assays used here. None of the peptides tested have any substantive activity in increasing cGMP in tubules

Stemosphere

Stemosphere is a student run science publication that hosts scientific articles and videos. Each piece is created by students in the Latham Science Engagement Initiative, a University of Iowa science outreach program. Our goal is to make science fun, accessible, and educational and to engage the public in scientific discussions. All too often, science articles are either incredibly condescending and full of jargon or oversimplified and the integrity of the research is lost. In this blog, we hope to spark your interest in new research and scientific discoveries and communicate scientific topics in an easy-to-digest way. Stemosphere is completely student directed and edited, with each piece written by fellows in the LSEI. The other main goal of Stemosphere was to promote the science outreach projects completed by the Latham fellows. Therefore, all projects are archived on Stemosphere with descriptions and pictures. In addition, Stemosphere also hosts vlogs, created by a Latham fellow, that follow the journeys of other students in LSEI as they implement their STEM outreach projects. In order to attract an audience to Stemosphere, social media accounts for Twitter, Instagram, and Facebook were used to promote articles and the projects of other Latham fellows.
