Altruism: Biological Rationale vs. Christian Love Command

The idea of altruism and self-sacrifice appears counter to a simple view of evolution. While a “survival of the fittest” mindset occurs in some Darwinian views, there are counter-examples of animals and humans with cooperative, pro-social, and even self-sacrificial behavior. Social animals such as bees and ants work for the community and provide for the queen due to a haploid-diploid system of genetic relatedness. Some humans sacrifice their lives and money to promote the well-being of others even without genetic relatedness and, rarely, without reciprocity. We will explore why human animals often help people who are less fortunate by giving away financial and time resources. Such behaviors appear to violate natural law. A further complication in human behavior is the “do unto others” teaching in several religions including the Christian love command

Learning outcomes assessment revisited: A new instructor’s perspective

Learning Outcomes Assessment (LOA) has been a key component of lesson planning in information literacy for some time now. This poster session will trace the LOA movement back to its roots in scientific management, explore its value to the mission of information literacy while also detail its limitations. Drawing on the library and information science literature, theories from critical pedagogy, and my own experience in teaching, this poster session intends to argue that while LOA misses out on crucial aspects of teaching and learning, it can in fact provide a powerful mechanism to aid new instructors in developing their practice

Using satellites to investigate the sensitivity of longwave downward radiation to water vapor at high elevations

Many studies suggest that high-elevation regions may be among the most sensitive to future climate change. However, in situ observations in these often remote locations are too sparse to determine the feedbacks responsible for enhanced warming rates. One of these feedbacks is associated with the sensitivity of longwave downward radiation (LDR) to changes in water vapor, with the sensitivity being particularly large in many high-elevation regions where the average water vapor is often low. We show that satellite retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Clouds and the Earth’s Radiant Energy System (CERES) can be used to expand the current ground-based observational database and that the monthly averaged clear-sky satellite estimates of humidity and LDR are in good agreement with the well-instrumented Center for Snow and Avalanche Studies ground-based site in the southwestern Colorado Rocky Mountains. The relationship between MODIS-retrieved precipitable water vapor and surface specific humidity across the contiguous United States was found to be similar to that previously found for the Alps. More important, we show that satellites capture the nonlinear relationship between LDR and water vapor and confirm that LDR is especially sensitive to changes in water vapor at high elevations in several midlatitude mountain ranges. Because the global population depends on adequate fresh water, much of which has its source in high mountains, it is critically important to understand how climate will change there. We demonstrate that satellites can be used to investigate these feedbacks in high-elevation regions where the coverage of surface-based observations is insufficient to do so
