The discoverability of award-winning undergraduate research in history: Implications for academic libraries

Making scholarly information visible to web search engines is an ongoing challenge, and undergraduate research is no exception. Using a sample of award-winning undergraduate history papers and journals, the authors searched Google, Google Scholar, Microsoft Academic, and the authors' institutional repository to gauge the difficulty of locating these works. Given that many of these works were not easily found, results suggest that libraries and their institutions could be doing more to increase the discoverability of undergraduate research. Based on the success stories observed in this study, we offer strategies to libraries and librarians for increasing the visibility of undergraduate student research.     

The effects of exposure to violence and victimization across life domains on adolescent substance use

This study uses longitudinal data from the Project on Human Development in Chicago Neighborhoods (PHDCN) to examine the effects of exposure to school violence, community violence, child abuse, and parental intimate partner violence (IPV) on youths’ subsequent alcohol and marijuana use. We also examine the cumulative effects of being exposed to violence across these domains. Longitudinal data were obtained from 1,655 adolescents and their primary caregivers participating in the PHDCN. The effects of adolescents’ exposure to various forms of violence across different life domains were examined relative to adolescents’ frequency of alcohol and marijuana use three years later. Multivariate statistical models were employed to control for a range of child, parent, and family risk factors. Exposure to violence in a one-year period increased the frequency of substance use three years later, though the specific relationships between victimization and use varied for alcohol and marijuana use. Community violence and child abuse, but not school violence or exposure to IPV, were predictive of future marijuana use. None of the independent measures of exposure to violence significantly predicted future alcohol use. Finally, the accumulation of exposure to violence across life domains was detrimental to both future alcohol and marijuana use. The findings support prior research indicating that exposure to multiple forms of violence, across multiple domains of life, negatively impacts adolescent outcomes, including substance use. The findings also suggest that the context in which exposure to violence occurs should be considered in future research, since the more domains in which youth are exposed to violence, the fewer “safe havens” they have available. Finally, a better understanding of the types of violence youth encounter and the contexts in which these experiences occur can help inform intervention efforts aimed at reducing victimization and its negative consequences.     

Visual attention to size and number of pattern details by term and preterm infants during the first six months.

2 dimensions inversely varied in previous complexity studies using checker-boards were varied independently. Patterns with more elements, angles, and information as well as patterns with larger elements received longer fixation at all ages, but initially prepotent size preferences decreased with age while number preferences became stronger. Further analysis showed the inadequency of contour length as the stimulus determinant for, or of increasing "optimal complexity" with age as the interpretation of, these previous findings. Term-preterm comparisons at 5-week intervals proved changes were a function of prenatal plus postnatal development rather than age from birth alone.     

Abilities assessed by the K-ABC mental processing subtests: The perceptions of practitioners with varying degrees of experience

Eighty practitioners with varying levels of experience in the administration of the Kaufman Assessment Battery for Children (K-ABC) were asked to complete a K-ABC Abilities Matrix to indicate their perceptions of the specific abilities assessed by each of the ten K-ABC Mental Processing subtests. The practitioners' responses were compared to the perceptions of the K-ABC authors, and, in roughly half of the judgements, a majority of the practitioners agreed with the test authors, while the remaining judgements constituted majority disagreements. The practitioners associated additional psychoeducational abilities or skills, that had not been identified previously by the K-ABC authors, with several of the K-ABC subtests.     

Online Interactive Teaching Modules Enhance Quantitative Proficiency of Introductory Biology Students

There is widespread agreement within the scientific and education communities that undergraduate biology curricula fall short in providing students with the quantitative and interdisciplinary problem-solving skills they need to obtain a deep understanding of biological phenomena and be prepared fully to contribute to future scientific inquiry. MathBench Biology Modules were designed to address these needs through a series of interactive, Web-based modules that can be used to supplement existing course content across the biological sciences curriculum. The effect of the modules was assessed in an introductory biology course at the University of Maryland. Over the course of the semester, students showed significant increases in quantitative skills that were independent of previous math course work. Students also showed increased comfort with solving quantitative problems, whether or not they ultimately arrived at the correct answer. A survey of spring 2009 graduates indicated that those who had experienced MathBench in their course work had a greater appreciation for the role of mathematics in modern biology than those who had not used MathBench. MathBench modules allow students from diverse educational backgrounds to hone their quantitative skills, preparing them for more complex mathematical approaches in upper-division courses.     

Factors Influencing Student Acceptance of Mobile Learning in Higher Education

The purpose of this study was to explore the acceptance of mobile learning by students in a higher education setting. The unified theory of acceptance and use of technology (UTAUT) was extended to include hedonic motivation, operationalized as enjoyment, as well as social influence in a field study involving the adoption of iPad mobile devices. Survey data were collected from 171 college students and analyzed using partial least squares structural equation modeling (PLS-SEM). The results indicated that enjoyment and performance expectations were important factors influencing the acceptance of mobile learning in this context. For those engaged in the mobile learning pilot project upon which this study was based, the use of the UTAUT and the results provided a theory-based empirical approach to support an assessment that the pilot project goals were achieved. Overall, students perceived iPads to be useful and enjoyable tools for accomplishing educational tasks and improving learning outcomes.
