Jacksonville State University is a regional public coeducational university located in Jacksonville, Alabama, USA. Founded in 1883, Jacksonville State offers programs of study in five academic units leading to Bachelor's, Master's, Education Specialist, and Doctorate in addition to continuing and distance education programs. In the Fall semester of 2011, JSU began offering the school's first doctoral degree, Doctor of Science in Emergency Management.The university was founded as Jacksonville State Normal School, and in 1930 the name changed to Jacksonville State Teachers College, and again in 1957 to Jacksonville State College. The university began operating as Jacksonville State University in 1967. In 2008, the university celebrated its 125th anniversary.JSU currently has an enrollment of nearly 9,000 students, with nearly 500 faculty members . Jacksonville State's Business School was ranked within the nation's 90th percentile by the Princeton Review. The current University President is Dr. William A. Meehan.Jacksonville State University is accredited by the Southern Association of Colleges and Schools . In addition, 40 academic programs earned specialized programmatic accreditations. These programs include business, education, engineering and technology, nursing, social work, drama, art, music, computer science, family and consumer science, and communication.221 international students representing 73 countries were enrolled in the 2013-2014 academic year. The University has run its International House program, an international exchange program, for over 60 years. Wikipedia.

The objectives of the current study were to investigate the origin of polyploidy in the woody bamboos and examine putative hybrid relationships in one major lineage (the temperate woody bamboos, tribe Arundinarieae). Phylogenetic analyses were based on sequence data from three nuclear loci and 38 species in 27 genera. We identify six ancestral genome donors for contemporary bamboo lineages: temperate woody bamboos (tribe Arundinarieae) contain genomes A and B, tropical woody bamboos (tribe Bambuseae) contain genomes C and D, and herbaceous bamboos (tribe Olyreae) contain genome H; some hexaploid paleotropical bamboos contain genome E in addition to C and D. Molecular data indicate that allopolyploidy arose independently in temperate (AABB) and tropical woody lineages (CCDD and CCDDEE), and speciation occurred subsequent to polyploidization. Moreover, hybridization has played a surprising and recurrent role in bamboo evolution, generating allohexaploid species in the paleotropical clade and intergeneric hybrids among the allotetraploid temperate bamboos. We suggest this complex history of reticulate evolution is at least partially responsible for the taxonomic difficulty associated with the woody bamboos. This newly-resolved phylogenetic framework reflects a major step forward in our understanding of bamboo biodiversity and has important implications for the interpretation of bamboo phylogenomics. © 2014 New Phytologist Trust.

Teamwork factors can facilitate team members, committing themselves to the purposes of maximizing their own and others' contributions and successes. It is important for online instructors to comprehend students' expectations on learning collaboratively. The aims of this study were to investigate online collaborative learning experiences and to identify important factors that were crucial for building teamwork trust. A qualitative research method was utilized in the study. Data were collected from students' responses of three open-ended questions and interviews. The results indicated that students who enjoyed working in the group setting had a good relationship with their team members and they trusted their team members. In contrast, the questionable behaviors of members (lack of communication and low level of individual accountability) were negative factors of their teamwork experiences. In addition, students considered individual accountability, familiarity with team members, commitment toward quality work, and team cohesion were important factors for building trust with team members. Quantitative analyses confirmed that teamwork trust was correlated significantly with two of the important factors for building trust indicated by team members: familiarity with members (r = .74) and team cohesion (r = .79). Implications and recommendations for future research were also discussed. © 2012 Elsevier B.V. All rights reserved.

The current study examined the effects of responses on error-adjacent trials (i.e., those immediately preceding or following errors) on age differences in measures of intraindividual variability and the shape of response time (RT) distributions on a two-back task. Removing error-adjacent responses reduced variability as measured by the coefficient of variation, but did so similarly for younger and older adults. However, older adults standard deviations (SDs) were less than those of younger adults with comparable RTs, raising questions regarding the validity of the coefficient of variation. An ex-Gaussian analysis revealed that removing the RTs on error-adjacent trials reduced the length of the tails of distributions and the skewness of the distributions. These properties were reduced more for older adults than for younger adults. These results indicate that the influence of error-adjacent trials should be considered when analyzing intraindividual variability and the shape of RT distributions to test theories of cognitive aging. © 2015 © 2015 Taylor & Francis.

Perchlorate is a significant contaminant of concern in surface and ground water. It has been extensively investigated for uptake and accumulation by land and aquatic plants. Although, the uptake and accumulation of perchlorate by plants is well investigated, no study was undertaken to investigate how perchlorate may affect plants's physiological and metabolic processes. Arabidopsis thaliana and Nicotiana tobacum plants were used as model organisms to investigate the effects of perchlorate to some selected physiological and molecular processes of the plants. Six-week-old Arabidopsis and tobacco plants were exposed to varying concentrations of perchlorate (C10 4~) in irrigation water and the rates of the light reactions of photosynthesis of their chloroplasts along with the activities of the Superoxide Dismutase (SOD) and of the Ascorbate Peroxidase (APO) were measured. Chlorosis and necrosis were noted in all plants irrigated with perchlorate solutions but not in the control plants. Measurement data indicated that perchlorate concentration as low as 1 mM was enough to induce a 2.15 fold decrease in the rate of the light reactions of photosynthesis and to induce a 1.2 folds increase in the total protein expressed, to cause a 2.0 folds increase in SOD activity and 1.7 folds increase in APO activity in Arabidopsis; while in tobacco plants, the same concentration of perchlorate was enough to induce 3.12 folds decrease in the rate of the light reactions and 1.7 fold increase in SOD activities and a 1.3 fold increase in APO activities, indicating that perchlorate in soil or irrigation water will not only interfere with plants growth and development but will also induce oxidative stress to plants. © 2011 Asian Network for Scientific Information.

The history of artificial intelligence control systems for use in space is discussed in this paper. The two fields started separately in the 1950s and first merged in the 1970s due to control requirements for a Jet Propulsion Laboratory project. While spacecraft have a special need for AI systems due to communications delays and other factors, much of AI control system development is conducted for earth-based applications. To mitigate risk factors, space-bound AI systems are also tested extensively via simulations. As a result, virtually all AI space control systems get their start on the ground. Additionally, ground support systems are required to facilitate communication with and command of AI controlled and other space craft. Numerous successful missions incorporating or controlled by AI technology have been launched. Further, many more are planned. Examples of ground, space-flown and future AI control missions are all discussed herein. While, spacecraft AI was born out of necessity (due to communication delays and such), it is now becoming desirable for other reasons such as cost savings and mission enhancement.
