Are Individual Differences in Media Multitasking Habits Associated with Changes in Brain Activation: An ERP Investigation of Multitasking and Cognitive Control
As the number of mobile phone users grows, understanding the impact of multiple streams of media on media multitasking and related neural correlates is especially pertinent. This research aims to understand the association between media multitasking tendencies on the neural correlates underlying cognitive control using event-related potentials (ERPs). Specifically, we were interested in the N2 and P3, ERPs that measure neural activation underlying aspects of cognitive control. Based on the literature, we predicted that participants who have high media multitasking scores would show more negative N2 activation and more positive P3 activation than their low media multitasking counterparts during an AX-CPT task, indicating less efficient neural processing. However, we did not find the expected pattern of results. It is possible that reactive and proactive control are not related to digital media multitasking or it may be that some potential design issues impacted our results. The current paper will explore these issues
Auditory cortical responses in the cat to sounds that produce spatial illusions
Humans and cats can localize a sound source accurately if its spectrum is fairly broad and flat(1-3), as is typical of most natural sounds. However, if sounds are filtered to reduce the width of the spectrum, they result:in illusions of sources that are very different from the actual locations, particularly in the up/down and front/back dimensions(4-6). Such illusions reveal that the auditory system relies on specific characteristics of sound spectra to obtain cues for localization(7). In the-auditory cortex of cats, temporal firing patterns of neurons can signal the locations of broad-band sounds(8-9). Here we show that such spike patterns systematically mislocalize sounds that have been passed through a narrow-band filter. Both correct and incorrect locations signalled by neurons can be predicted quantitatively by a model of spectral processing that also predicts correct and incorrect localization judgements by human listeners(6). Similar cortical mechanisms, if present in humans, could underlie human auditory spatial perception.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/62778/1/399688a0.pd
Pharmacological Pain Management in Pediatric Sickle Cell Pain Crisis: An Integrative Review
Pain management among pediatric patients with sickle cell disease continues to pose a challenge to healthcare providers. Underlying disease processes, family perceptions of painful events, and injury add to the complexity of effective pain management in this population. Sickle cell disease is the most common variant of the many hemoglobinopathies in the world, with painful episodes as the most common presentation to emergency departments for treatment beginning as early as 6 to 8 months of age. Sickle cell pain crisis continues to receive less-than-effective pain management treatment resulting in frequent hospitalizations, chronic pain, and increased morbidity and mortality. This integrative review provides a synthesis of the published evidence regarding the best approach to pharmacological management of pain during sickle cell pain crisis in the pediatric population. Results of these studies strongly correlate pharmacological pain management of pediatric sickle cell crisis pain on consensus and expert opinion with few strong research studies conducted to completion. The literature also suggest new knowledge in the areas of pathophysiology and pharmacogenomics in provider decisions in pharmacological management of pediatric sickle cell crisis pain is not seen in clinical practice resulting in undertreatment and repeated hospital admissions. The undertreatment of pediatric sickle cell crisis pain contributes to morbidity and early mortality in this patient population
A Summative Evaluation of FlightSafety International\u27s Computer Assisted Instruction known as Principles of Troubleshooting
The objective of this experimental research was to ascertain if cognitive skills developed by the Principles of Troubleshooting (POT) educational course improved aircraft fault diagnostic ability in aircraft maintenance trainees. Sixty randomly chosen Embry-Riddle Aeronautical University (ERAU) students served as control and experimental subjects with the POT course as the independent variable. Because random assignment was possible, a posttest-only control group design was used. Thirty ERAU maintenance trainees who had received basic and advanced ERAU fault diagnostic training were administered the POT course. A practical test administered to both groups using two tailed t tests for independent means indicated improvement in fault diagnostic ability

A History Of The Associate Degree Nursing Program In Nevada, 1963-1983
This study discusses the development of the present four associate degree nursing programs in the state of Nevada. It begins with a brief overview of the development of the associate degree program in the nation. Next it examines the survey of Nevada\u27s nursing needs and the plans and actions taken by citizens of Nevada in response to the survey; The first school began in what later became the University of Nevada, Las Vegas. In 1967 federal money was obtained to operate associate degree and baccalaureate nursing classes as a joint venture between the Reno and Las Vegas campuses of the University of Nevada. These classes were conducted by closed circuit television. By the end of the television project, the community college system was beginning, and an associate degree program opened in the Reno area community college. The next program opened in Elko at Northern Nevada Community College, in 1978, and in 1982 Western Nevada Community College in Carson City began its program; The development of the programs was influenced by the growth of associate degree nursing programs in the nation, and by the growth of the university and community college system in Nevada. The curriculums for the schools followed the general pattern set by Mildred Montag; The study closes with some questions about the future which revolve about the preparation and utilization of the associate degree nurse versus changes in health care provisions and escalating costs
A National Survey of Manpower Utilization and Future Needs of Consulting Engineering Firms Engaged in Water Pollution Control
Introduction: As part of the overall evaluation of manpower needs in the environmental field, a survey of architectural and engineering firms was jointly sponsored by the Consulting Engineers Council, the American Association of Professors in Sanitary Engineering and the Environmental Protection Agency. A questionnaire was mailed to 8,.5. engineering and architectural firms that subscribe to the magazin
