The northern redbelly dace (Chrosomus eos) and the finescale dace (C. neogaeus) have hybridized to produce an all-female, asexual hybrid (C. eos-neogaeus) that reproduces by sperm-limited parthenogenesis (gynogenesis). However, in this system, gynogenesis is not 100 % efficient; triploid females are occasionally formed which reproduce as sexuals, producing nuclear males and females of the paternal species (generally C. eos). Thus, the asexual lineage continually produces occasional males that can serve as a sperm source. Because (almost) all hybrid offspring are females, the hybrid population has the potential to grow more quickly and even outcompete the sexuals, thus eliminating their own sperm source. The current research uses behavioral testing, ovarian analyses, and modeling to examine three hypotheses for the maintenance of the sexual/asexual complex: male discrimination against hybrid females, fecundity differences between sexual and asexual females, and production of nuclear male sexuals from the asexual lineage. Results suggest that males do not discriminate against asexual females, and that both sexual and asexual females have similar fecundities, eliminating these hypotheses as potential coexistence mechanisms. However, computer simulations of population growth support the hypothesis that occasional triploidy within the hybrid population supplies enough breeding males to maintain the sexual/asexual complex. © 2015, Springer-Verlag Berlin Heidelberg.

We present a mixed-methods approach to community-based assessment design that engages tribal college and university faculty, students, and science educators, as well as experts in cultural knowledge from the Blackfeet and Diné (Navajo) nations. Information from cultural experts, gathered through a combination of sequential surveys and focus group sessions, was analyzed to identify important themes with regard to assessment and geoscience content within the context of these communities. While experts use a variety of assessment approaches in their classrooms, only pre and posttesting and portfolios were found to be most valuable. Experts indicated that the primary role of assessment was to monitor student progress, steer instruction, and prepare students for success; thus, assessment should be tied to the course goals. Experts differed on their views regarding sources of bias in testing, but overall they agreed that test language and content were both strong sources of bias. They indicated that input on assessment would help to incorporate local context and provide a mechanism for combating bias. Surveys completed by tribal college faculty and Native American students from Blackfeet Community College (BCC) and Arizona State University (ASU) provided information on the themes of geoscience, native science, place, and culture. Participants provided a variety of examples of important geoscience concepts that focused on (1) traditional geoscience concepts (e.g., the composition of Earth materials), (2) Earth system concepts (e.g., the environment and ecosystems), and (3) interactions between native culture and geoscience (e.g., incorporation of native language in science curriculum). Combined, these data offer the basis for developing place-based and culturally informed geoscience assessments by revealing geoscience content that is important to the local community. To aid in assessment design, one-on-one interviews with tribal college faculty and science educators, as well as students from BCC and ASU, provided specific feedback on the question validity of select items from an existing instrument: the Geoscience Concept Inventory (GCI). Emergent themes from the interview transcripts address assessment content, language, and format and reference school science, cultural knowledge, physical places, and connections to the local landscape (e.g., sense of place). Together, these data (1) address the validity of the GCI as a standardized assessment measure in these student populations and (2) provide the basis for developing open-ended assessment questions and concept inventory-like questions that incorporate this feedback. © 2014 National Association of Geoscience Teachers.

This study sought to evaluate the statistical power of aviation research published in four prominent peer-reviewed journals (Collegiate Aviation Review, Journal of Air Transportation Worldwide, Journal of Aviation/Aerospace Education and Research, and International Journal of Applied Aviation Studies). Further, this study investigated whether power was mentioned or calculated as well as if articles included details on effect size(s). The study yielded 128 articles that included statistical testing and provided enough information to calculate power. From these articles a total of 1,692 statistical tests were analyzed. The average power of these tests was .277 considering a small effect size, .685 when considering a medium effect size, and .874 when assuming a large effect size. Considering that a medium effect size is generally utilized when there is no research-based reason to use an alternative level and that the accepted minimum power value is .80, aviation research appears to be underpowered. Also, only 5.6% of articles conducted an a priori power analysis whilst 11.9% mentioned power. Among studies that included statistical testing, only 4.2 % calculated effect size. Thus aviation research commonly fails to provide critical research data. Guidance on ways researchers can improve power and/or reduce sample size requirements are provided. Suggestions for future research and policies are also provided. Source

This project is establishing a three-semester curriculum, Introduction to Research I-III, that begins in the freshman year. Students complete two semester-long projects, begin reading peer-reviewed scientific articles while learning about faculty research on campus, and choose a faculty advisor to aid them in writing a research proposal. Experienced juniors and seniors serve as mentors for the freshman and sophomores. It is based on a successful pilot project designed to test the feasibility of the design.
Intellectual Merit: Students gain an understanding of how research is conducted and skills they can use either in their graduate work or as they enter the work place. Faculty have an opportunity to establish a research program at the institution that serves as the base for the work of other students.
Broader Impact: This system is designed to serve as a model for other departments on campus and for other Predominantly Undergraduate Serving Institutions because of an educational research component designed to study the effects of undergraduate research on academic success and students career choices.

Cardiovirus infections inhibit nucleocytoplasmic trafficking by Leader protein-induced phosphorylation of Phe/Gly-containing nucleoporins (Nups). Recombinant Leader from encephalomyocarditis virus, Theiler[U+05F3]s murine encephalomyelitis virus and Saffold virus target the same subset of Nups, including Nup62 and Nup98, but not Nup50. Reporter cell lines with fluorescence mCherry markers for M9, RS and classical SV40 import pathways, as well as the Crm1-mediated export pathway, all responded to transfection with the full panel of Leader proteins, showing consequent cessation of path-specific active import/export. For this to happen, the Nups had to be presented in the context of intact nuclear pores and exposed to cytoplasmic extracts. The Leader phosphorylation cascade was not effective against recombinant Nup proteins. The findings support a model of Leader-dependent Nup phosphorylation with the purpose of disrupting Nup-transportin interactions. © 2015 Elsevier Inc. Source
