Sustaining O-gah-pah: An Analysis of Quapaw Language Loss and Preservation

The story of the Quapaw, or Downstream People, and their language is an integral part of both the American Indian experience and the larger, universal tapestry of multilingualism. Despite historical setbacks and contemporary challenges, preserving the virtually extinct Quapaw language adds to the diverse cultural narrative of the Americas and shares a nation’s unique story with the rest of humanity. Consulting linguists, historical records, tribal members, and experts on indigenous studies, this project aims to answer questions concerning the state of the Quapaw tongue: how it arrived at virtual extinction, what is being done to preserve it, and the challenges associated with trying to maintain a dying language. Additionally, this project demonstrates the value of the Quapaw language, as the survival of the Downstream People serves as a powerful reminder of the North American heritage and the culturally unifying forces at the heart of the indigenous identity

Testosterone Fluctuations in Young Men: The Difference Between Interacting With Like and Not-Like Others

The current study investigated young men\u27s testosterone level changes as a result of interacting with other men. Male participants (n = 84) were led to believe that a group they would be interacting with was either similar to them or not similar. The interaction was then one of two types: the other group members were inclusive, or the others excluded the participant during the group interaction. Participants provided saliva samples before and after the interaction. Results suggest that interacting with highly similar men increases circulating testosterone whereas interacting with highly dissimilar men actually lowers testosterone. The nature of the interaction was less important than similarity. Considering that testosterone surges may relate to attempts to gain status within one\u27s group, the results are interpreted as consistent with viewing hormonal changes as a mechanism to alter current behavioral propensities in ways that are likely to be most adaptive. Exploratory analyses suggest a methodologically interesting suppressor effect of the self-report items in predicting testosterone changes

Using the DELPHI Method to Collect Feedback on Student\u27s Perceptions of Teaching Quality

In educational institutions, teaching effectiveness is a highly valued asset among administrators, professors, and students alike. Information gathered from students is often used as a basis for promotion and tenure decisions (Abrami & d’Apollonia, 1999; Waters, Kemp, & Pucci, 1988), and, ideally, formative purposes. However, students do not always believe that their evaluations carry much weight (Chen & Hoshower, 2003; Spencer & Schmelkin, 2002). This is likely due to the fact that summarized results from student evaluations often do not get in the hands of professors until after that particular course has concluded and, therefore, the feedback does not directly benefit the students who provided it. The goal of the current paper is to introduce a method that can be used by instructors to evaluate the effectiveness of their teaching in a particular course in such a way as to implement change in the course if necessary for those very same students. First, we will discuss teaching effectiveness in general; second we will introduce the DELPHI method and its usefulness in evaluating effective teaching; and third we will report on the results of using this method in our courses with the goal of improving the learning experience for the students providing the feedback

Low growth resilience to drought is related to future mortality risk in trees

Severe droughts have the potential to reduce forest productivity and trigger tree mortality. Most trees face several drought events during their life and therefore resilience to dry conditions may be crucial to long-term survival. We assessed how growth resilience to severe droughts, including its components resistance and recovery, is related to the ability to survive future droughts by using a tree-ring database of surviving and now-dead trees from 118 sites (22 species, >3,500 trees). We found that, across the variety of regions and species sampled, trees that died during water shortages were less resilient to previous non-lethal droughts, relative to coexisting surviving trees of the same species. In angiosperms, drought-related mortality risk is associated with lower resistance (low capacity to reduce impact of the initial drought), while it is related to reduced recovery (low capacity to attain pre-drought growth rates) in gymnosperms. The different resilience strategies in these two taxonomic groups open new avenues to improve our understanding and prediction of drought-induced mortality.Fil: DeSoto, Lucía.
