High Repeatability

AbstractThis study aims to determine the degree to which Portable Automated Rapid Testing (PART), a freely-available program running on a tablet computer, is capable of reproducing standard laboratory results. Undergraduate students were assigned to one of three within-subject conditions that examined repeatability of performance on a battery of psychoacoustical tests of temporal fine structure processing, spectro-temporal amplitude modulation, and targets in competition. The Repeatability condition examined test/retest with the same system, the Headphones condition examined the effects of varying headphones (passive and active noise-attenuating), and the Noise condition examined repeatability in the presence of recorded cafeteria noise. In general, performance on the test battery showed high repeatability, even across manipulated conditions, and was similar to that reported in the literature. These data serve as validation that suprathreshold psychoacoustical tests can be made accessible to run on consumer-grade hardware and performed in less controlled settings. This dataset also provides a distribution of thresholds that can be used as a normative baseline against which auditory dysfunction can be identified in future work.

The psychological effect of the pandemic and measures taken in response to control viral spread are not yet well understood in university students; in-depth qualitative analysis can provide nuanced information about the young adult distress experience. Undergraduate students ( N = 624) in an early US outbreak “hotspot” completed an online narrative writing about the impact and distress experienced due to the COVID-19 pandemic. Data were collected April-May 2020. A random selection of 50 cases were sampled for thematic analysis. Nine themes were identified: viral outbreak distress, fear of virus contraction/transmission, proximity to virus, dissatisfaction with public response, physical distancing distress, social distancing distress, academic and school-related distress, disruptive changes in health behavior and routines, financial strain and unemployment, worsening of pre-existing mental health problems, and social referencing that minimizes distress. Future work is needed to understand the persistence of the distress, in addition to developing methods for assessment, monitoring, and mitigation of the distress.

Abstract Background Prior research reported that motivational beliefs that individuals attach to specific tasks predict continuing interest and persistence in the task. A motivational approach may be particularly useful for understanding undergraduate students’ engagement with research in their first and second years in college. The current study utilizes the expectancy-value theory of achievement motivation to qualitatively explore how much and in what ways early year undergraduate researchers value their research experience and what kinds of costs they associate with it. Results The results revealed that intrinsic value had the highest expression in participants’ motivation to engage in research. The second most expressed value type was the utility value of undergraduate research with regards to obtaining the desired outcomes, and attainment value played the least important role in participants’ motivation to engage in research. Findings also indicated that some of the participants associated a cost(s) to their research experience. The highest mentioned perceived cost was opportunity cost, where participants commented on losing other valued alternatives when engaging in research. Participants commented on the time, effort, or amount of work needed to engage in research, and a few participants commented on the emotional cost associated with their research experience in terms of the fear of failure. Conclusion As perceived cost is the least studied in the expectancy-value framework, this study contributes to cost values within college students, particularly about early year undergraduate researchers. The findings of this study can form the basis for future work on exploring ways to increase the values and decrease the costs students experience in their undergraduate research experiences.

In engineering disciplines, visualization can provide an essential mode to facilitate student understanding of important and abstract concepts. Learning through a medium that combines course materials with game characteristics can be a powerful tool for education. This approach is expected to improve student willingness to learn, which will in turn increase the interests of high school and undergraduate students towards engineering as a future career. In this paper, three teaching modules based on the Gaming and Interactive Visualization for Education (GIVE) in three universities will be described in detail with enhanced game characteristics. Also, using the newly developed assessment tools, the evaluation data from the students who have experienced the GIVE system will be analyzed. More specifically, the three modules are designed and illustrated in this paper for the Flight Mechanics, Introduction to Electrical Engineering, and Design and Manufacturing. The following game characteristics have been considered and implemented in the modules: progressively balanced goal, feedback, time sensitive scoring, adaptive scoring, meaningful visual presentation, emotional involvement, avoiding guess, constitutive rule, operational rule, background, challenges, and rewards. Along with the course module development and implementation, the outcomes have been assessed using our evaluation system. The results have been analyzed and suggestions have been given for future work.

As many as one in three first-year undergraduate students cannot make it back for the sophomore year. The low retention rate for students, especially engineering students, is a widespread problem. In this paper, the quantification of course difficulty and student stress is discussed, followed by a student stress model which can integrate student stress into the course scheduling problem. Some future work is presented in the conclusion.

Using an established global academic interest scale, academic interest dimensions of undergraduate ( n = 326) and graduate ( n = 401) students were compared. The four-factor structure, consisting of passion for learning, confidence in the future, career aspiration, and self-expression, held for both student groups. However, the item scores and mean factor scores as well as the pattern of factor correlations differed between the two groups. While the sample of graduate students exhibited greater levels of passion for learning, the undergraduate students showed higher levels of confidence in the future. Overall, a broad range of correlates of academic interest employed in this study provided construct validity evidence of academic interest, supporting the main tenants of the motivational theory of life-span development. Limitations and directions for future work are discussed.

No routine laboratory biomarkers perform well enough in diagnosing COVID-19 in isolation for them to be used as a standalone diagnostic test or to help clinicians prioritize patients for treatment. Instead, other diagnostic tests are needed. The aim of this work was to statistically summarise routine laboratory biomarker measurements in COVID-19-positive and -negative patients to inform future work. A systematic literature review and meta-analysis were performed. The search included names of commonly used, routine laboratory tests in the UK NHS, and focused on research papers reporting laboratory results of patients diagnosed with COVID-19. A random effects meta-analysis of the standardized mean difference between COVID-19-positive and -negative groups was conducted for each biomarker. When comparing reported laboratory biomarker results, we identified decreased white blood cell, neutrophil, lymphocyte, eosinophil, and platelet counts; while lactate dehydrogenase, aspartate aminotransferase, and alanine aminotransferase were elevated in COVID-19-positive compared to COVID-19-negative patients. Differences were identified across a number of routine laboratory biomarkers between COVID-19-positive and -negative patients. Further research is required to identify whether routine laboratory biomarkers can be used in the development of a clinical scoring system to aid with triage of patients.

Adequate Data

The COVID-19 pandemic has raised awareness of the need for robust and reliable remote testing of auditory function. Here, we examine how the recently introduced Portable Automatic Rapid Testing (PART) system–validated to produce precise psychoacoustical data in consumer hardware [Larrea-Mancera et al., JASA, 2020]—performs when data are collected remotely on participant-owned uncalibrated smart- phones. To accomplish this, we compare data collected remotely, to a published dataset that was collected in a lab- based sample using standardized calibrated hardware. Performance was examined in a group of 40 participants with PART assessments administered via a video-call. Results largely matched the normative dataset collected in the laboratory with, on average, slightly worse performance and similar repeatability; however, the rate of outlying performance increase for some assessments suggesting that some testing settings may not be appropriate for adequate data collection in some cases. These data suggest the feasibility of remote auditory testing on participants’ own devices for suprathreshold tests of auditory processing. Future work is needed to better determine the adequacy of different remote settings for reliable psychoacoustic data collection or clinical use.

Temporal Modifiers

This paper reports some results of a study in which two groups of individuals—undergraduate students and professional meteorologists at Oregon State University—completed a short questionnaire concerning their interpretations of terminology commonly used in public weather forecasts. The questions related to terms and phrases associated with three elements: 1) cloudiness—fraction of sky cover; 2) precipitation—spatial and/or temporal variations; and 3) temperature—specification of intervals. The students' responses indicate that cloudiness terms are subject to wide and overlapping ranges of interpretation, although the interpretations of these terms correspond quite well to National Weather Service definitions. Their responses to the precipitation and temperature questions reveal that some confusion exists concerning the meaning of spatial and temporal modifiers in precipitation forecasts and that some individuals interpret temperature ranges in terms of asymmetric intervals. When compared to the students' responses, the meteorologists' responses exhibit narrower ranges of interpretation of the cloudiness terms and less confusion about the meaning of spatial/temporal precipitation modifiers. The study was not intended to be a definitive analysis of public understanding of forecast terminology. Instead, it should be viewed as a primitive form of the type of forecast-terminology study that must be undertaken in the future. Some implications of this investigation for future work in the area are discussed briefly.

This article discusses about Power Quality (PQ) as a teaching subject and addresses the methodology employed in the theoretical/expositive PQ lectures for undergraduate students held at the Laboratory of Analysis of Power Quality Monitoring – LAMQEE, located at São Carlos School of Engineering (EESC), University of São Paulo (USP). It will be covering challenges handled, positive aspects and new learning opportunities based at adopted methodology. Theoretical classes were supported by new tools of pedagogical aid to develop learning skills. Examples of tools that could be mentioned are real time computer simulations projected in multi-media equipment, discussions of technical-scientific articles, as well as the use of a Digital Arbitrary Signal Generator combined with a PQ analyzer. With the aim of increase and retain the enrolled students’ interest, practical exercises were added to the course and provided with performance comments concluded activities. This methodology was implemented with the vital cooperation of a student of the Program of Education Improvement (PAE) supported by USP. The PQ classes supervised in association of a PAE scholarship support in teaching activities, promoted better interest and involvement of students during the lectures. Additionally, it improves the teaching atmosphere quality, satisfy and lectures content. Students’ self-confidence on the subject PQ concepts and developed performs was verified and the enhanced number of final course papers in topics correlated to PQ. Despite challenges and upgrades that should be applied, the effects observed so far show that many of the pedagogical instruments, when correctly applied, are capable of enhance the study and attention of significant topics associated to PQ. Likewise, the instruments also encourage and inspire students to learn PQ subjects key and initiate them to the academic research atmosphere and upcoming professional activities. Finally, other activities are still on the list of actions for future work, for example, it would be recommended to have a feedback mechanism of the students, validating all the methodology adopted, strengths and weaknesses of the material developed, the presentation of the lesson and the attendance after the lecture.
