Leveling the playing field: Exploiting technology to enhance tertiary learning

This paper reports on an on-going case study project to explore ICT/ eLearning across several disciplines and with students from diverse backgrounds at tertiary level in New Zealand. The project has been designed to address issues of tertiary-level pedagogy, epedagogy, and research with the goal of building eLearning capacity, leveraging pedagogical change, and closing participatory gaps for students and lecturers. Initial design decisions, the pedagogy that has informed the case studies, and the challenges and benefits of working across subjects and levels in a multi-disciplinary team are described. We also discuss research knowledge mobilization within our own instructional context and more broadly elsewhere

Adoption of innovative e-learning support for teaching: A multiple case study at the University of Waikato

In response to recent social, economic, and pedagogical challenges to tertiary-level teaching and learning, universities are increasingly investigating and adopting elearning as a way to engage and motivate students. This paper reports on the first year of a two-year (2009-2010) qualitative multiple case study research project in New Zealand. Using perspectives from activity theory and the scholarship of teaching, the research has the overall goal of documenting, developing, and disseminating effective and innovative practice in which e-learning plays an important role in tertiary teaching. A “snapshot” of each of the four 2009 cases and focused findings within and across cases are provided. This is followed by an overall discussion of the context, “within” and “across” case themes, and implications of the research

Promoting Population Health in Local Communities: Parental Perceptions of an Embedded Movement and Physical Activity Program for a Preschool Population

Background: Many children reach kindergarten lacking age-appropriate motor skills because of a lack of access to early intervention services or a lack of continued early intervention beyond 3 years of age. Research suggests sedentary children become sedentary adults, which contributes to a growing population of unhealthy Americans with chronic health conditions, such as high blood pressure, diabetes, heart disease, and psychosocial difficulties. Parents often are not aware of the benefits of engaging in physical activity or possess a lack of awareness of their local resources. A community based preschool movement program was created to foster physical activity and promote carryover through participation in family activities. Method: A program evaluation design model was used to explore parental perceptions of their child’s interest and participation in physical activities. Knowledge of local resources was also measured. Results: The parent responses reported an increase in interest for physical activities by their child along with an increase in parental understanding of the value of movement in daily routines. The family’s awareness of local resources increased as a result of the movement program and supporting materials. Conclusion: Collaborating with existing entities can further parental education about movement and non-sedentary routines. Future research is needed to measure outcomes over time

Airline Pilot Perceptions of Stress and Self-Reported Fatigue: A Cross-Sectional Study

In the air transportation sector, fatigue is a known problem influencing safety. Over the past two decades, fatigue mitigation has gained increased regulatory emphasis. The psychosocial construct of perceived stress, however, has been less studied and emphasized, though decades of research demonstrates stress’s impact on psychosocial and physiological wellbeing and safety performance. This observational, cross-sectional study measured airline pilots’ perceived stress levels alongside selected fatigue factors. Data was gathered from a sample of 144 airline pilots and analyzed using non-parametric statistics to explore the relationship between pilots’ perceptions of their own stress levels over the previous month with their answers to a questionnaire on fatigue factors. The objective here was both assessment of Cohen’s (1983) Perceived Stress Scale (PSS) as a tool for measuring chronic stress among airline pilots, along with classification and juxtaposition of organizational, professional, social and biological fatigue factors that may contribute to chronic stress. This study fills a gap in the literature on reliable, repeatable methodologies for studying chronic occupational stress, and importantly–establishes correlations between two safety-influencing constructs not previously explored side-by-side. Results support the validity of the PSS for subjective assessment of stress among airline pilots, thereby contributing to the body of knowledge on measuring chronic stressors and fatigue factors in the airline industry. This study also highlights the relevance of additional emphasis in this area of study. The implications of qualitatively exploring a relationship between these two related safety-influencing constructs may provide a different angle for future practical solutions and regulatory guidance

Pilot Source Study 2018: Five Years after the FOQ Rule—New-Hire First Officer Backgrounds and their Performance in US Regional Airline Training

After the Pilot Source Study (PSS) 2015 was published, there was concern that the data were collected too soon after the First Officer Qualification Rule compliance date. The Collaborative Research Committee of the Aviation Accreditation Board International (AABI) voted to undertake the PSS 2018 to determine whether the results of the PSS 2015 were still valid. In fall 2018, five research teams collected 9,776 pilot records from five regional airlines and analyzed these data. In the PSS 2018, the criteria for success were: ≥90% completions and ≤1 extra training event. In rank order, the following pilots were most successful in regional airline initial training: (1) pilots who had an undergraduate GPA of 3.3 or higher, (2) pilots who graduated from college within 5 years of their hire date, (3) pilots who had either a military R-ATP (750 hours) or an institutional R-ATP (1,000 hours), (4) pilots who graduated from an AABI-accredited flight program, (5) pilots who had 1,500 or fewer total flight hours, (6) pilots who had a bachelor degree. In addition to these variables, multivariate analysis showed that the following variables provide additional prediction and classification for success: age, younger; flight instructor, yes; military pilot, yes; previous FAA failures, fewer. All four PSSs (2010, 2012, 2015, and 2018) have substantiated the 2010 ANPRM statement: ‘‘…experience is not measured in flight time alone’’

Effectiveness of Virtual Reality Simulations for Civilian, Ab Initio Pilot Training

Aviation training in the immersive Virtual Reality (VR) world has the power to overcome physical constraints, presenting cues and stimuli that would not be available in flight, nor in a two-dimensional (2D) environment. This gives VR powerful potential as a simulation tool for learning complex skills and maneuvers in the cockpit. This study evaluated the effectiveness of VR simulations as compared to traditional 2D desktop simulations in teaching maneuvers and skills to ab initio (inexperienced) civilian pilot trainees. This quasi-experimental project involved 17 freshman pilot students in an experimental college course at a private university campus in the fall semester of 2020. The participants were split into two sections: Section 1 completed CBT activities and simulations in 2D only, while Section 2 completed CBT activities in 2D and simulations in VR. Academic performance data was collected in the Canvas Learning Management System, broken down by understanding of a maneuver learned in a given lesson module. Descriptive statistics collected included quizzes, discussion board activity, and simulation completion scores. Paired samples t-tests compared perceived benefits of using the various course materials. Researchers also administered post-semester surveys to gather both qualitative and quantitative data, in which participants shared their perceptions of the course, preference for learning material type, and general feedback. Results indicated that students in both groups found the sims/tutorials and VR to be enjoyable and gratifying; the majority of students indicated that simulations were preferred over other learning materials. Early results indicate that although the students perceived that the simulations were beneficial, there were no significant differences in the final course scores or learning rates between those who utilized 2D sims as opposed to VR sims. The most important finding is that for ab initio pilots, VR simulations do not hinder learning mastery, as compared with traditional 2D desktop simulations

Usability of the SedLine® electroencephalographic monitor of depth of anaesthesia in pigs: a pilot study.

To investigate the usability of the SedLine® monitor in anaesthetized pigs. Five juvenile healthy pigs underwent balanced isoflurane-based general anaesthesia for surgical placement of a subcutaneous jugular venous port. The SedLine® was applied to continuously monitor electroencephalographic (EEG) activity and its modulation during anaesthesia. Computer tomography and magnetic resonance were performed to investigate the relationship between electrodes' positioning and anatomical structures. The pediatric SedLine® EEG-sensor could be easily applied and SedLine®-generated variables collected. An EEG Density Spectral Array (DS) was displayed over the whole procedure. During surgery, the EEG signal was dominated by elevated power in the delta range (0.5-4 Hz), with an underlying broadband signal (where power decreased with increasing frequency). The emergence period was marked by a decrease in delta power, and a more evenly distributed power over the 4-40 Hz frequency range. From incision to end of surgery, mean SedLine®-generated values (± standard deviation) were overall stable [23.0 (± 2.8) Patient State Index (PSI), 1.0% (± 3.8%) Suppression Ratio (SR), 8.8 Hz (± 2.5 Hz) Spectral Edge Frequency 95% (SEF) left, 7.7 Hz (± 2.4 Hz) SEF right], quickly changing during emergence [75.3 (± 11.1) PSI, 0.0 (± 0.0) SR, 12.5 (± 6.6) SEF left 10.4 (± 6.6) SEF right]. Based on the imaging performed, the sensor does not record EEG signals from the same brain areas as in humans. SedLine®-DSA and -generated variables seemed to reflect variations in depth of anaesthesia in pigs. Further studies are needed to investigate this correlation, as well as to define the species-specific brain structures monitored by the EEG-sensor

Kennedy Space Center (KSC) Launch Pad Avian Abatement Efforts Including Related KSC Road Kill Reduction Effort

While birds might seem harmless, there's a good reason for the concern. During the July 2005 launch of Discovery on mission STS-1 14, a vulture soaring around the launch pad impacted the shuttle's external tank just after liftoff. With a vulture's average weight ranging from 3 to 5 pounds. a strike at a critical point on the Shuttle -- like the nose or wing leading thermal protection panels -- could cause catastrophic damage to the vehicle. The foam chunk that fatefully struck Columbia's wing in 2003 weighed only 1.7 pounds. (Cheryl L. Mansfield "Bye Bye Birdies" 2006) To address this issue, NASA formed an "Avian Abatement Team". The team goal is to have safer Shuttle missions by reducing the vulture population at KSC near the pad area thereby reducing the probability of another vulture strike during a Shuttle launch

UV/Ozone treatment to reduce metal-graphene contact resistance

We report reduced contact resistance of single-layer graphene devices by using ultraviolet ozone (UVO) treatment to modify the metal/graphene contact interface. The devices were fabricated from mechanically transferred, chemical vapor deposition (CVD) grown, single layer graphene. UVO treatment of graphene in the contact regions as defined by photolithography and prior to metal deposition was found to reduce interface contamination originating from incomplete removal of poly(methyl methacrylate) (PMMA) and photoresist. Our control experiment shows that exposure times up to 10 minutes did not introduce significant disorder in the graphene as characterized by Raman spectroscopy. By using the described approach, contact resistance of less than 200 {\Omega} {\mu}m was achieved, while not significantly altering the electrical properties of the graphene channel region of devices.Comment: 17 pages, 5 figure

Permutation entropy is not an age-independent parameter for EEG-based anesthesia monitoring.

BACKGROUND An optimized anesthesia monitoring using electroencephalographic (EEG) information in the elderly could help to reduce the incidence of postoperative complications. Processed EEG information that is available to the anesthesiologist is affected by the age-induced changes of the raw EEG. While most of these methods indicate a "more awake" patient with age, the permutation entropy (PeEn) has been proposed as an age-independent measure. In this article, we show that PeEn is also influenced by age, independent of parameter settings. METHODS We retrospectively analyzed the EEG of more than 300 patients, recorded during steady state anesthesia without stimulation, and calculated the PeEn for different embedding dimensions m that was applied to the EEG filtered to a wide variety of frequency ranges. We constructed linear models to evaluate the relationship between age and PeEn. To compare our results to published studies, we also performed a stepwise dichotomization and used non-parametric tests and effect sizes for pairwise comparisons. RESULTS We found a significant influence of age on PeEn for all settings except for narrow band EEG activity. The analysis of the dichotomized data also revealed significant differences between old and young patients for the PeEn settings used in published studies. CONCLUSION Based on our findings, we could show the influence of age on PeEn. This result was independent of parameter, sample rate, and filter settings. Hence, age should be taken into consideration when using PeEn to monitor patient EEG
