Valdosta State University, also referred to as VSU, or Valdosta State, is an American public university and is one of the three regional universities in the University System of Georgia. Valdosta State is located on a 168-acre campus at the heart of the city of Valdosta. VSU serves over 13,000 undergraduate and graduate students representing 157 Georgia counties, all 50 states, Puerto Rico, the Virgin Islands, American Samoa and Washington, D.C. and hosts over 300 international students from 76 countries. VSU also offers classes at Moody Air Force Base north of Valdosta in Lowndes County, and Kings Bay Naval Base in Camden County.Degree levels offered at Valdosta State include: Associate's, Bachelor's, Master's, Education Specialist, and Doctoral. The university comprises the colleges of Arts and science, Business Administration, Education, Arts, and Nursing. The Graduate School also includes the Divisions of Social Work and Library Science.VSU is also home to the six-week residential Governor's Honors Program during the summer for academically and artistically oriented Georgia high school students.

In deaf education, the sign language skills of teacher and interpreter candidates are infrequently assessed; when they are, formal measures are commonly used upon preparation program completion, as opposed to informal measures related to instructional tasks. Using an informal picture storybook task, the authors investigated the receptive and expressive narrative sign language skills of 10 teacher and interpreter candidates in a university preparation program. The candidates evaluated signed renditions of two signing children, as well as their own expressive renditions, using the Signed Reading Fluency Rubric (Easterbrooks & Huston, 2008) at the completion of their fifth sign language course. Candidates’ evaluations were compared overall and across 12 sign language indicators to ratings of two university program professors. Some variation existed across ratings for individual indicators, but generally the candidates were aware of and could accurately rate their own abilities and those of two signing children. © 2015, Gallaudet University Press.

It is well established that massive consumption of plants by the abundant and diverse assemblage of savanna ungulates in East Africa competitively suppresses the native guild of herbivorous to omnivorous small mammals. An important role of woody plant suppression in the Acacia-dominated savannas for this guild of rodents, when released from ungulate competition, has been demonstrated only recently, but without direct evidence of which species are involved. In an effort to establish which of the common species in this guild are most likely to impact growth of trees and forbs, as opposed to grasses or insects, or both, I present data on atomic and isotopic ratios of fecal carbon and nitrogen from 8 commonly occurring muroid rodents from savanna and bush habitats on the Laikipia Plateau of central Kenya: Acomys percivali, Acomys wilsoni, Aethomys hindei, Arvicanthis niloticus, Mastomys natalensis, Mus spp. (thought to be mostly M. minutoides), Saccostomus mearnsi, and Gerbilliscus robustus. In this region where all grasses are C4 and all trees and other nongrasses are C3, different ratios of 13C:12C (δ13C) in plant tissues give pure grazers, pure browsers, and mixed-feeding herbivores distinctive carbon isotope signatures. Degree of omnivory is revealed by C:N and, arguably, by δ15N, but the latter is influenced by dietary protein quality and varies widely by plant species and soil type. Joint consideration of stable-isotope data, total C:N, and microhistological analysis of feces allowed better resolution of dietary niche of each species than any of these data sets could, alone. Grass was either coequal to browse (dicots) or dominated the plant portion of each species' diet, which was somewhat unexpected given rodents' hypothesized role in limiting Acacia recruitment. All species consumed some arthropods. A. niloticus, the only diurnal species, was the most herbivorous, being largely a grazer. S. mearnsi, A. hindei, and M. natalensis were mixed-feeding (grass-browse) herbivores. Mus spp. and Acomys spp. were omnivores whose plant components were largely grass. G. robustus was primarily an insectivore-omnivore whose smaller plant component was grass. Both S. mearnsi and A. niloticus displayed a significant increase in proportion of C4 grasses in the diet in periods following significant rains, a pattern previously documented from δ13C diet studies in large mammalian herbivores. Fecal δ15N was significantly higher for rodents that consumed more grass and for rodents released from competition with ungulates, suggesting a partial mechanism for that competitive release. S. mearnsi, followed by A. hindei and M. natalensis, were most likely to feed on woody dicots including Acacia. ©2013 American Society of Mammalogists.

Google's App Inventor for Android (AIA) is the newest visual "blocks" programming language designed to introduce students to programming through creation of mobile applications (apps). AIA opens up the world of mobile apps to novice programmers. Success stories of using AIA to introduce college students to programming exist. We used AIA in computing summer camps for high school students that we offer at our university. This paper is an experience report about using AIA in our camps. We provide a detailed description of designing our camps with AIA including the process of selecting and setting-up an Android device and instructional materials that we developed and made available to everyone. We evaluated our camps through surveys to determine the effects on the students. We found that there was mostly a slight increase in the favorable disposition towards computing. We also share our successes with using AIA and what still needs improvement for wider use. © 2012 ACM.

The synchronization of circadian rhythms in sleep, endocrine and metabolic functions with the environmental light cycle is essential for health, and dysfunction of this synchrony is thought to play a part in the development of many neurological disorders. There is a demonstrable need to develop new therapeutics for the treatment of neurological disorders such as depression and schizophrenia, and oxytocin is currently being investigated for this purpose. There are no published reports describing activity of oxytocin receptor ligands on mammalian circadian rhythms and that, then, is the purpose of this study. Non-peptide oxytocin receptor ligands that cross the blood brain barrier were systemically injected in hamsters to determine their ability to modulate light-induced phase advances and delays of circadian wheel running rhythms. The oxytocin receptor agonist WAY267464 (10 mg/kg) inhibited light induced phase advances of wheel running rhythms by 55%, but had no effect on light-induced phase delays. In contrast, the oxytocin receptor antagonist WAY162720 (10 mg/kg) inhibited light-induced phase delays by nearly 75%, but had no effect on light-induced phase advances. Additionally, WAY162720 was able to antagonize the inhibitory effects of WAY267464 on light-induced phase advances. These results are consistent for a role of oxytocin in the phase-delaying effects of light on circadian activity rhythms early in the night. Therefore, oxytocin may prove to be useful in developing therapeutics for the treatment of mood disorders with a concomitant dysfunction in circadian rhythms. Investigators should also be cognizant that oxytocin ligands may negatively affect circadian rhythms during clinical trials for other conditions. © 2014 Elsevier B.V.

This article presents receptive and expressive American Sign Language skills of 85 students, 6 through 22 years of age at a residential school for the deaf using the American Sign Language Receptive Skills Test and the Ozcaliskan Motion Stimuli. Results are presented by ages and indicate that students' receptive skills increased with age and were still developing across this age range. Students' expressive skills, specifically classifier production, increased with age but did not approach adult-like performance. On both measures, deaf children with deaf parents scored higher than their peers with hearing parents and many components of the measures significantly correlated. These results suggest that these two measures provide a well-rounded snapshot of individual students' American Sign Language skills. © The Author 2014.
