An Instrument for Measuring Teachers’ Trust in AI-Based Educational Technology

Evidence from various domains underlines the key role that human factors, and especially, trust, play in the adoption of technology by practitioners. In the case of Artificial Intelligence (AI) driven learning analytics tools, the issue is even more complex due to practitioners’ AI-specific misconceptions, myths, and fears (i.e., mass unemployment and ethical concerns). In recent years, artificial intelligence has been introduced increasingly into K-12 education. However, little research has been conducted on the trust and attitudes of K-12 teachers regarding the use and adoption of AI-based Educational Technology (EdTech). The present study introduces a new instrument to measure teachers’ trust in AI-based EdTech, provides evidence of its internal structure validity, and uses it to portray secondary-level school teachers’ attitudes toward AI. First, we explain the instrument items creation process based on our preliminary research and review of existing tools in other domains. Second, using Exploratory Factor Analysis we analyze the results from 132 teachers’ input. The results reveal eight factors influencing teachers’ trust in adopting AI-based EdTech: Perceived Benefits of AI-based EdTech, AI-based EdTech’s Lack of Human Characteristics, AI-based EdTech’s Perceived Lack of Transparency, Anxieties Related to Using AI-based EdTech, Self-efficacy in Using AI-based EdTech, Required Shift in Pedagogy to Adopt AI-based EdTech, Preferred Means to Increase Trust in AI-based EdTech, and AI-based EdTech vs Human Advice/Recommendation. Finally, we use the instrument to discuss 132 high-school Biology teachers’ responses to the survey items and to what extent they align with the findings from the literature in relevant domains. The contribution of this research is twofold. First, it introduces a reliable instrument to investigate the role of teachers’ trust in AI-based EdTech and the factors influencing it. Second, the findings from the teachers’ survey can guide creators of teacher professional development courses and policymakers on improving teachers’ trust in, and in turn their willingness to adopt, AI-based EdTech in K-12 education.
Combined treatment of prednisone and hydroxychloroquine may improve outcomes of frozen embryo transfer in antinuclear antibody-positive patients undergoing IVF/ICSI treatment

Background The influence of anti-nuclear antibody (ANA) on induced ovulation was controversial, and the effect of prednisone plus hydroxychloroquine (HCQ) treatment on frozen embryo transfer outcomes of in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) for ANA-positive women was unclear. Methods Fifty ANA-positive women and one-hundred ANA-negative women matched for age and anti-Mullerian hormone (AMH) were included from a Reproductive Medical Central of a University Hospital. Sixty-one oocytes pick-up (OPU) cycles in ANA+ group and one-hundred OPU cycles in ANA− group were compared; 30 frozen embryo transfer cycles without treatment and 66 with prednisone plus HCQ treatment among ANA-positive women were compared. Results There was no statistical difference in number of retrieved oocytes (13.66 ± 7.71 vs 13.72 ± 7.23, p = .445), available embryos (5.23 ± 3.37 vs 5.47 ± 3.26, p = .347), high-quality embryos (3.64 ± 3.25 vs 3.70 ± 3.52, p = .832), and proportion of high-quality embryos (26.5% vs. 26.7%, p = .940). Biochemical pregnancy rate (33.3% vs. 68.2%, p < .05), clinical pregnancy rate (20.0% vs. 50.1%, p < .05), and implantation rate (5.6% vs. 31.8%, p < .05) were lower, and pregnancy loss rate (83.3% vs. 23.1%, p < .05) was higher in patients with treatment than no treatment. Conclusion The influence of ANA on number of retrieved oocytes, available embryos, high-quality embryos, and proration of high-quality embryos was not found. The treatment of prednisone plus HCQ may improve implantation rate, biochemical pregnancy rate, and clinical pregnancy rate, and reduce pregnancy loss rate in frozen embryo transfer outcomes for ANA-positive women.
Simultaneous modulation and fiber-optic transmission of 10-Gb/s baseband and 60-GHz-band radio signals on a single wavelength

A simultaneous modulation and fiber-optic transmission of a 10-Gb/s baseband signal and a 60-GHz RF signal with 155-Mb/s differential-phase-shift-keying (DPSK) data on a single wavelength is investigated. To the authors' knowledge, it is experimentally demonstrated for the first time that both a 10-Gb/s on-off-keying baseband signal and a 60-GHz RF signal with 155-Mb/s DPSK data are simultaneously modulated with a single optical modulator and transmitted over 40-km-long dispersion-shifted fiber (DSF). There exists the received optical power capable of achieving a bit error rate of 10/sup -9/ simultaneously for both the RF and baseband signals. The degradations due to the nonlinearity of the electroabsorption modulator for the baseband and RF signals are also investigated theoretically and clarified numerically.
EEG Frontal Asymmetry in Dysthymia, Major Depressive Disorder and Euthymic Bipolar Disorder

In the last few decades, the incidence of mood disorders skyrocketed worldwide and has brought an increasing human and economic burden. Depending on the main symptoms and their evolution across time, they can be classified in several clinical subgroups. A few psychobiological indices have been extensively investigated as promising markers of mood disorders. Among these, frontal asymmetry measured at rest with quantitative EEG has represented the main available marker in recent years. Only a few studies so far attempted to distinguish the features and differences among diagnostic types of mood disorders by using this index. The present study measured frontal EEG asymmetry during a 5-min resting state in three samples of patients with bipolar disorder in a Euthymic phase (EBD, n = 17), major depressive disorder (MDD, n = 25) and persistent depressive disorder (PDD, n = 21), once termed dysthymia. We aimed to test the hypothesis that MDD and PDD lack the typical leftward asymmetry exhibited by normal as well as EBD patients, and that PDD shows greater clinical and neurophysiological impairments than MDD. Clinical scales revealed no symptoms in EBD, and significant larger anxiety and depression scores in PDD than in MDD patients. Relative beta (i.e., beta/alpha ratio) EEG asymmetry was measured from lateral frontal sites and results revealed the typical greater left than right frontal beta activity in EBD, as well as a lack of asymmetry in both MDD and PDD. The last two groups also had lower bilateral frontal beta activity in comparison with the EBD group. Results concerning group differences were interpreted by taking into account both the clinical and the neurophysiological domains.
Laboratory Model 50 kW Hall Thruster

A 0.46 meter diameter Hall thruster was fabricated and performance tested at powers up to 72 kilowatts. Thrusts up to 2.9 Newtons were measured. Discharge specific impulses ranged from 1750 to 3250 seconds with discharge efficiencies between 46 and 65 percent. Overall specific impulses ranged from 1550 to 3050 seconds with overall efficiencies between 40 and 57 percent. Performance data indicated significant fraction of multiple-charged ions during operation at elevated power levels. Cathode mass flow rate was shown to be a significant parameter with regard to thruster efficiency.
Analyzing on-road emissions of light-duty vehicles with Portable Emission Measurement Systems (PEMS)

The mission of the JRC-IE is to provide support to Community policies related to both nuclear and non-nuclear energy in order to ensure sustainable, secure and efficient energy production, distribution and use. Legal Notice Neither the European Commission nor any person acting on behalf of the Commission is responsible for the use which might be made of this publication. (*) Certain mobile telephone operators do not allow access to 00 800 numbers or these calls may be billed. Emissions testing in the laboratory forms an essential part of the European type approval procedure for light-duty vehicles. The approach yields reproducible and comparable emissions data and provides clear design criteria for vehicles that have to comply with applicable emission limits. Although emission limits have become increasingly stringent in the past decade, road transport remains the most important source of urban air pollution in Europe with respect to NO X (nitrogen oxides) and CO (carbon monoxide). Several studies have indicated that in particular on-road NO X emissions of light-duty diesel vehicles might substantially exceed emission levels as identified during emissions testing in the laboratory. Still, a comprehensive analysis of on-road emissions of light-duty diesel and gasoline vehicles is unavailable to date. This report addresses the existing knowledge gaps by using Portable Emission Measurement Systems (PEMS) to analyze the on-road emissions of 12 light-duty diesel and gasoline vehicles that comply with Euro 3-5 emission limits and comprise small and midsize passenger cars, two transporters, and a minivan. The selected vehicles where tested on four test routes, representing rural, urban, uphill/downhill, and motorway driving. The PEMS results indicate that average NO X emissions of diesel vehicles (0.93 ± 0.39 g/km), including Euro 5 diesel vehicles (0.62 ± 0.19 g/km), substantially exceed respective Euro 3-5 emission limits. The observed deviations range from a factor of 2-4 for average NO X emissions over entire test routes up to a factor of 14 for average NO X emissions of individual averaging windows. By comparison, on-road NO X emissions of gasoline vehicles as well as CO and THC (total hydrocarbon) emissions of both diesel and gasoline vehicles generally stay within Euro 3-5 emission limits. The share of NO 2 (nitrogen dioxide) in the total NO X emissions reaches 60% for diesel vehicles but is substantially lower for gasoline vehicles (0-30%). The tested light-duty diesel and gasoline vehicles emit during on-road testing on average 189 ± 51 g CO …
Assessment of Different Regiments of Early Oral Feeding in Comparison to Delayed Feeding After Elective Uncomplicated Cesarean Section: A Randomized Control Trial

Aim: Starting oral feeding after caesarian section enhances bowel function return, patient's ambulation, and patient recovery. We aimed to evaluate effectiveness of two different approaches of early oral feeding following section on gastrointestinal function, and patient satisfaction. Materials and Methods: In this randomized control study, 300 pregnant women with elective uncomplicated cesarean section done from October 2019 to March 2020 at Cairo University teaching hospital with were randomly allocated into three feeding groups. Results: Significant differences were noticed in patients’ satisfaction and time interval to return of gastrointestinal function, ambulation, regular diet, and hospital stay between the three groups and between the two groups of early feeding (P value < 0.05 for all) with highest satisfaction and shortest intervals noticed at introducing soft foods early irrespective of return of intestinal sounds (The first early feeding group). Non-significant differences noted concerning postoperative complications between the three groups or between the two groups of early feeding apart from vomiting found to be higher in the early feeding groups, but the cases were mild and easily treatable. Conclusion: Early oral feeding reduces the time needed for normal bowel function return and increases satisfaction of the patients with no detrimental significant effects on the gastrointestinal complication.
Environment in institutional care settings as a promoting factor for older individuals’ mobility: A systematic review

Abstract Background Mobility is important for health and well‐being; however, older individuals in institutional care settings are relatively sedentary. The environment has an increased influence on mobility in older age due to changes in individual functioning; thus, environmental mobility support solutions for this population are needed. Objectives The aim of this systematic review was to identify elements of the environment that have been used in the content and delivery of interventions to promote mobility and to assess the effects of these interventions on mobility outcomes. Design A systematic literature search was conducted using CINAHL and MEDLINE from the earliest date through 30 September 2020 for randomised controlled trials, quasi‐experimental and pre‐post design studies. Inclusion and critical appraisal of articles were conducted by two independent researchers. Data were extracted and synthesised. Setting and participants Studies were included if they had employed some element of the environment in the content and/or delivery of the intervention and had assessed mobility‐related outcomes of older individuals in institutional long‐term care settings providing full‐time care. Measures Studies were included if they reported data on mobility‐related outcomes including aspects of physical activity, physical function, life space and functional autonomy. Results Eight studies were included. Physical, social and symbolic elements of the environment were utilised in the interventions. Positive effects on mobility outcomes were reported in exercise interventions utilising environmental elements mostly as supportive components. Conclusions and implications Empirical evidence about effective mobility interventions employing elements of the environment as main intervention components is lacking. A serious dilemma exists about the need for older individuals’ independence and mobile/active late life and the lack of support for such initiatives in long‐term care. Given the emphasised relationship of the environment and mobility with age due to changes in functioning, environmental solutions require further examination.

The Cost of LEED—An Analysis of the Construction Costs of LEED and Non-LEED Banks

This study is an analysis of the initial building costs for two Leadership in Energy and Environmental Design (LEED) banks and eight non-LEED banks with similar building types and sizes located in western Colorado. The purpose of this study was to compare the costs of these banks, and to assess costs directly associated with LEED certification. The analysis examines total building costs, square footage costs, soft costs, and hard costs per MasterFormat Division. The study finds that the building costs of the LEED banks are similar to and within the same ranges as non-LEED banks. Additionally, the direct cost associated with seeking LEED certification is estimated to be below 2% of the total project cost.
The effect of pulsatile versus non-pulsatile flow during cardiopulmonary bypass on cerebral oxygenation: A randomized trial

Background The present study aims to compare regional oxygen supply determined by Near-Infrared Spectroscopy in the course of pulsatile perfusion with non-pulsatile perfusion during cardiopulmonary bypass in patients undergoing valvular heart surgery. Methods In this prospective randomized single-blinded trial, we enrolled adult subjects aged 18–65 years scheduled for elective valvular heart repair/replacement surgery with non-stenotic carotid arteries, employing a consecutive sampling method. Eligible patients were then randomly assigned in a 1:1 ratio to pulsatile or non-pulsatile perfusion during aortic cross-clamp. The primary outcome was regional cerebral oxygenation monitored by Near-Infrared Spectroscopy in each group. Results Seventy patients were randomly assigned, and each group comprised 35 patients. Mean age was 46.8 and 46.5 years in pulsatile and non-pulsatile groups, respectively. There were no significant between-group differences in regional cerebral oxygen saturation at different time points of cardiopulmonary bypass (p-value for analysis of variance repeated measures: 0.923 and 0.223 for left and right hemispheres, respectively). Moreover, no significant differences in regional cerebral oxygen saturation levels from baseline between pulsatile and non-pulsatile groups at all desired time points for the left (p = 0.51) and right (p = 0.22) hemispheres of the brain were detected. Conclusion Pulsatile perfusion during cardiopulmonary bypass does not offer superior regional cerebral oxygenation measured by Near-Infrared Spectroscopy than non-pulsatile perfusion during cardiopulmonary bypass. Nonetheless, the efficacy of pulsatile flow in the subgroup of patients in whom cerebral blood flow is impaired due to carotid artery stenosis needs to be explored and evaluated by this method in future studies.
Confidence limits for impact speed estimation from pedestrian projection distance

A key element of study of the biomechanics of pedestrian injuries from vehicle collisions is the determination of pre-impact vehicle speed. Pedestrian projection distances are an important means to determine collision speed, particularly as tyre brake marks are not readily observable with ABS brakes. A number of models have been developed by the authors, which include recent analytical models for forward [1] and wrap projection [2] impact. These models are novel as they include explicit modeling of the impact phase. They have been validated against the available test data, showing very good comparisons, and are therefore ideal for further statistical analysis. Confidence limits for speed estimates are set out for various purposes including injury research and litigation. The models show that the distribution of predicted collision speeds from projection distance can be large when a high degree of confidence is required. Some of this uncertainty is due to the impact phase where parameters such as duration and restitution are unknown for individual collisions, in addition to other confounding factors that are difficult to quantify. However the effects of the coefficient of retardation during the projection phase and the mass ratio between pedestrian and the striking vehicle can be readily determined. This paper analyses the influence of reduced variability of the input parameters on the predicted range of impact velocities. Analysis for known coefficients of retardation and mass ratio values yields the minimum prediction uncertainty due to the variability of the impact phase parameters alone. Results show that significant improvements in prediction uncertainty can be achieved by exact knowledge of the pedestrian to vehicle mass ratio and of the coefficient of retardation between the pedestrian and the road surface. In practice, while the mass ratio can be determined for individual collisions there is significant uncertainty as to the coefficient of retardation values, as these are influenced by the kinematics of the pedestrian during projection and ground impacts, in addition to factors such as road surface condition and contamination. However, overall data is available for wet and dry road conditions. Tables are presented for impact speed prediction from projection distance for various conditions and confidence levels.
Whole Exome Sequencing-Based Identification of a Novel Gene Involved in Root Hair Development in Barley (Hordeum vulgare L.)

Root hairs play a crucial role in anchoring plants in soil, interaction with microorganisms and nutrient uptake from the rhizosphere. In contrast to Arabidopsis, there is a limited knowledge of root hair morphogenesis in monocots, including barley (Hordeum vulgare L.). We have isolated barley mutant rhp1.e with an abnormal root hair phenotype after chemical mutagenesis of spring cultivar ‘Sebastian’. The development of root hairs was initiated in the mutant but inhibited at the very early stage of tip growth. The length of root hairs reached only 3% of the length of parent cultivar. Using a whole exome sequencing (WES) approach, we identified G1674A mutation in the HORVU1Hr1G077230 gene, located on chromosome 1HL and encoding a cellulose synthase-like C1 protein (HvCSLC1) that might be involved in the xyloglucan (XyG) synthesis in root hairs. The identified mutation led to the retention of the second intron and premature termination of the HvCSLC1 protein. The mutation co-segregated with the abnormal root hair phenotype in the F2 progeny of rhp1.e mutant and its wild-type parent. Additionally, different substitutions in HORVU1Hr1G077230 were found in four other allelic mutants with the same root hair phenotype. Here, we discuss the putative role of HvCSLC1 protein in root hair tube elongation in barley.
High field emission related thin oxide wearout and breakdown

A model describing high voltage induced thin oxide wearout and breakdown in terms of traps generated inside of the oxide by high field emission has been developed. This model has been shown to be able to describe much of the thickness, field, polarity, time and temperature dependences observed during thin oxide wearout and breakdown. <<ETX>>
Advanced Management Protocol of Transanal Irrigation in Order to Improve the Outcome of Pediatric Patients with Fecal Incontinence

Background: Transanal irrigation (TAI) is employed for children with fecal incontinence, but it can present several problems which require a study of their outcomes among different pathologies and without a tailored work up. The aim of our study was to evaluate the effectiveness of an advanced protocol in order to tailor TAI, prevent complications, and evaluate outcomes. Methods: We included 70 patients (14 anorectal malformation, 12 Hirschsprung’s disease, 24 neurological impairment, 20 functional incontinence) submitted to a comprehensive protocol with Peristeen®: fecal score, volumetric enema, rectal ultrasound, anorectal 3D manometry, and diary for testing and parameter adjustment. Results: Among the patients, 62.9% needed adaptations to the parameters, mainly volume of irrigated water and number of puffs of balloon. These adaptations were positively correlated with pre-treatment manometric and enema data. In each group, the improvement of score was statistically significant in all cases (p 0.000); the main factor influencing the efficacy was the rate of sphincter anomalies. The ARM group had slower improvement than other groups, whereas functional patients had the best response. Conclusions: Our results showed that TAI should not be standardized for all patients, because each one has different peculiarities; evaluation of patients before TAI with rectal ultrasound, enema, and manometry allowed us to tailor the treatment, highlighting different outcomes among various pathologies, thus improving the efficacy.
