Print or eFormat: preferences and factors that influence undergraduate student behavior
With my project I plan to conduct research into the information-seeking behaviors and methods of undergraduate students to determine what preferences they have concerning the format of required academic readings and research materials, and what factors influence this behavior. This research will be conducted by means of a review of the literature by scholars in the field of information-seeking behaviors, user studies in academic libraries, and what these scholars have found to be true about undergraduate studentsā information-seeking and preference behaviors when reading course-related materials and conducting research for those courses. The aspect of what factors influence information-seeking behavior provides librarians insight into the mindset of undergraduate students as a group, as opposed to preferences of an individual within the subset. Having an understanding of how undergraduate students seek information they require for their courses and in which format they prefer to have it available to them enables librarians and the field of library and information science to stay viable and fulfil one of its key missions; the key mission being to provide an environment that guides and assists undergraduate students to learn the materials and concepts taught in the studentsā academic courses and chosen field of study. By understanding all of the aspects mentioned above, the conclusion that I have come to is that what undergraduates are seeking (types of information) and why they are seeking that information (for what purpose have they sought out this information) are intertwined and play a predominant role in how undergraduates seek information

Children with severe malnutrition: can those at highest risk of death be identified with the WHO protocol?
Background With strict adherence to international recommended treatment guidelines, the case fatality for severe malnutrition ought to be less than 5%. In African hospitals, fatality rates of 20% are common and are often attributed to poor training and faulty case management. Improving outcome will depend upon the identification of those at greatest risk and targeting limited health resources. We retrospectively examined the major risk factors associated with early (<48 h) and late in-hospital death in children with severe malnutrition with the aim of identifying admission features that could distinguish a high-risk group in relation to the World Health Organization (WHO) guidelines. Methods and Findings Of 920 children in the study, 176 (19%) died, with 59 (33%) deaths occurring within 48 h of admission. Bacteraemia complicated 27% of all deaths: 52% died before 48 h despite 85% in vitro antibiotic susceptibility of cultured organisms. The sensitivity, specificity, and likelihood ratio of the WHO-recommended ādanger signsā (lethargy, hypothermia, or hypoglycaemia) to predict early mortality was 52%, 84%, and 3.4% (95% confidence interval [CI] = 2.2 to 5.1), respectively. In addition, four bedside features were associated with early case fatality: bradycardia, capillary refill time greater than 2 s, weak pulse volume, and impaired consciousness level; the presence of two or more features was associated with an odds ratio of 9.6 (95% CI = 4.8 to 19) for early fatality (p < 0.0001). Conversely, the group of children without any of these seven features, or signs of dehydration, severe acidosis, or electrolyte derangements, had a low fatality (7%). Conclusions Formal assessment of these features as emergency signs to improve triage and to rationalize manpower resources toward the high-risk groups is required. In addition, basic clinical research is necessary to identify and test appropriate supportive treatments

The High Costs of Large Enrollment Classes: Can Cooperative Learning Help?
We examine the potential for cooperative learning activities to offset costs of large enrollment courses. We use a quasi-experimental research design to examine achievement and course perceptions in small and large enrollment sections of microeconomic principles. While large enrollment sections attain lower levels of achievement (measured by course score) than those with smaller enrollments, this effect is partially mitigated by use of cooperative learning. Furthermore, while students in large enrollment sections report lower levels of satisfaction and learning than students in smaller sized classes, the use of cooperative learning eliminates the negative effects of increased class size on student perceptions
Redesigning Public Speaking: A Case Study in the Use of Instructional Design to Create the Interchange Model
This case study describes the redesign of Public Speaking at a Research I institution. An instructional analysis revealed strengths of and concerns about the existing model--large lecture with small lab sections. Criteria for a new model emerged from that analysis, all of which hinged on an overarching goal: The course should incorporate learning theory and disciplinary theory and should result in student learning, student skill development, and enhanced satisfaction among stakeholders. The Interchange Model, which included some online delivery, was developed to meet identified needs and was fleshed out with course materials and semester plans. The model was piloted and then fully implemented with positive results
Hybrid density functional theory description of N- and C-doping of NiO
The large intrinsic bandgap of NiO hinders its potential application as a photocatalyst under visible-light irradiation. In this study, we have performed first-principles screened exchange hybrid density functional theory with the HSE06 functional calculations of N- and C-doped NiO to investigate the effect of doping on the electronic structure of NiO. C-doping at an oxygen site induces gap states due to the dopant, the positions of which suggest that the top of the valence band is made up primarily of C 2p-derived states with some Ni 3d contributions, and the lowest-energy empty state is in the middle of the gap. This leads to an effective bandgap of 1.7 eV, which is of potential interest for photocatalytic applications. N-doping induces comparatively little dopant-Ni 3d interactions, but results in similar positions of dopant-induced states, i.e., the top of the valence band is made up of dopant 2p states and the lowest unoccupied state is the empty gap state derived from the dopant, leading to bandgap narrowing. With the hybrid density functional theory (DFT) results available, we discuss issues with the DFT corrected for on-site Coulomb description of these systems
