Investigation of Online Learning Satisfaction During COVID 19: In Relation to Academic Achievement

The aim of this research is; 1) investigating the level of online learning satisfaction among students during COVID 19; 2) analyzing the influence of differences in gender, years of study, major in determining online learning satisfaction among students during COVID 19; 3) to analyze the relationship between online learning satisfaction and student academic achievement during COVID 19. The population was 656 students at STKIP Singkawang, and then a sample of 357 students (87 males and 270 females) was taken using a simple random sampling technique. The instrument in this study was adapted from Aman's Satisfaction instrument, which was then used to collect research data. Data analysis using SPSS with descriptive statistical techniques, MANOVA, and correlation. The results showed that online learning satisfaction was at a high level, meaning that students were satisfied with the online learning that had been implemented. The major differences have a significant effect on determining online learning satisfaction. Intercorrelation shows that there is a significant relationship on each indicator of online learning satisfaction with academic achievement, meaning that the higher the satisfaction felt by students in online learning, the student's academic achievement will increase.
Ocular Age Pigment "A2-E": An Unprecedented Pyridinium Bisretinoid

which no remedy exists. It is generally accepted that the pigments are formed as a consequence of accumulation of debris resulting from incomplete digestion of phagocytosed outer segment disks in lysosomes. Among the compounds that accumulate in lipofuscin, the orange fluorophores have attracted wide interest since they are considered to be the possible cause of age-related decline of cell functions. In this communication we report the structure of the major fluorophore. This orange pigment was first isolated from >250 human donor eyes (age >40 years) by a series of silica gel column chromatography and preparative TLC. 3,4a Structural studies
The use of simulation as a teaching modality for paramedic education: a scoping review

Background: Simulation is a broad concept used as an education pedagogy for a wide range of disciplines. The use of simulation to educate paramedics is a frequently used but untested modality to teach psycho-motor skills, acquire new knowledge and gain competence in practice. This review identifies how simulation is currently being used for the education of paramedics, and establish the context for future application. Methods: A scoping review of the literature was undertaken following the PRISMA systematic approach. Flexible inclusion criteria were used to capture research and non-research articles that would contribute to the synthesis of literature with a specific knowledge base pertaining to simulation use for paramedic education. Results: Initial searching yielded 1388 records, of which 22 remained after initial title and abstract reading. Following secondary full-text screening, 18 articles were deemed appropriate for final inclusion: eight are research, two literature reviews and eight non-research. Across all the literature, a range of concepts are discussed: Skill vs Scenario, Virtual Learning, Inter-Professional Learning, Fidelity, Cost, Equipment, Improvement of Competency, Patient Safety, Perception of Simulation. Conclusion: It is evident that simulation is a primary teaching modality, consistently used to educate and train paramedics. Simulation is inherently effective at teaching clinical skills and building student competence in particular areas. Similarly, simulation is effective at providing paramedics with experiences and opportunities to learn in varied environments using differing techniques. This allows students to apply the relevant skills and knowledge when faced with real patients.
The Impact of Psycho-Social Interventions on the Wellbeing of Individuals With Acquired Brain Injury During the COVID-19 Pandemic

Individuals with Acquired Brain Injury (ABI) suffer chronic impairment across cognitive, physical and psycho-social domains, and the experience of anxiety, isolation and apathy has been amplified by the COVID-19 pandemic. A qualitative evaluation was conducted of 14 individuals with ABI who had participated in series of COVID adapted group-based intervention(s) that had been designed to improve wellbeing. Eight themes were identified: Facilitating Safety, Fostering Positive Emotion, Managing and Accepting Difficult Emotions, Promoting Meaning, Finding Purpose and Accomplishment, Facilitating Social Ties, (Re)Connecting to Nature, and Barriers to Efficacy. Findings are discussed with respects to recent theoretical developments in positive psychology and wellbeing science and support the use of online and outdoor interventions to enhance wellbeing in individuals living with ABI during the COVID-19 pandemic. This paper makes a unique contribution to second wave positive psychology (PP2.0) through the application of recent advances in wellbeing science to an ABI population during the COVID-19 pandemic. In doing so, this paper lays the foundation for new interventions that not only reduce impairment and distress, but also create opportunities for meaning and enhanced wellbeing in people living with chronic conditions and those individuals living with ABI in particular.
Assessing an Integral Treatment for Landfill Leachate Reverse Osmosis Concentrate

An integral treatment process for landfill leachate reverse osmosis concentrate (LLROC) is herein designed and assessed aiming to reduce organic matter content and conductivity, as well as to increase its biodegradability. The process consists of three steps. The first one is a coagulation/flocculation treatment, which best results were obtained using a dosage of 5 g L−1 of ferric chloride at an initial pH = 6 (removal of the 76% chemical oxygen demand (COD), 57% specific ultraviolet absorption (SUVA), and 92% color). The second step is a photo-Fenton process, which resulted in an enhanced biodegradability (i.e., the ratio between the biochemical oxygen demand (BOD5) and the COD increased from 0.06 to 0.4), and an extra 43% of the COD was removed at the best trialed reaction conditions of [H2O2]/COD = 1.06, pH = 4 and [H2O2]/[Fe]mol = 45. An ultra violet-A light emitting diode (UVA-LED) lamp was tested and compared to conventional high-pressure mercury vapor lamps, achieving a 16% power consumption reduction. Finally, an optimized 30 g L−1 lime treatment was implemented, which reduced conductivity by a 43%, and the contents of sulfate, total nitrogen, chloride, and metals by 90%. Overall, the integral treatment of LLROC achieved the removal of 99.9% color, 90% COD, 90% sulfate, 90% nitrogen, 86% Al, 77% Zn, 84% Mn, 99% Mg, and 98% Si; and significantly increased biodegradability up to BOD5/COD = 0.4.
Influence of Electrical Potential Distribution, Charge Transport, and Recombination on the Photopotential and Photocurrent Conversion Efficiency of Dye-Sensitized Nanocrystalline TiO2 Solar Cells: A Study by Electrical Impedance and Optical Modulation Techniques

The role of electrical potential, charge transport, and recombination in determining the photopotential and photocurrent conversion efficiency (IPCE) of dye-sensitized nanocrystalline solar cells was studied. Electrostatic arguments and electrical impedance spectroscopy (EIS) are used to obtain information on the electrical and electrochemical potential distribution in the cell. It is shown that on the macroscopic level, no significant electrical potential drop exists within the porous TiO2 when it contacts the electrolyte and that the electrical potential drop at the transparent conducting oxide substrate (TCO)/TiO2 interface occurs over a narrow region, one or two layers of TiO2. Analyses of EIS and other data indicate that both the photopotential of the cell and the decrease of the electrical potential drop across the TCO/TiO2 interface are caused by the buildup of photoinjected electrons in the TiO2 film. The time constants for the recombination and collection of the photoinjected electrons are measur.
Exploring caregiver experiences of stigma in Ghana: They insult me because of my child

Abstract Families of children with disabilities experience stigma by association with their child. This article examines social and internalised stigma experienced in the family by caregivers who participated in a caregiver programme in Ghana. Stigma is pervasive, and gendered, with most mothers blamed for bringing disability into the home. Emotional distress, isolation and lack of support are common experiences. We argue that the mothers can experience forms of disablism. Stigma is multi-layered, and a range of factors intersect with disability-related stigma, including poverty. A support group model can have a positive impact on caregiver internalised stigma and begin to address isolation. This should be part of a wider package of support to address wider structural issues. Families can play an important role in mediating change, but first we need to better understand the social disruption caused by disability-related stigma at the familial level. Points of interest Stigma amongst family members with a child with cerebral palsy, is very common in the Ghana context, and fuelled by traditional beliefs. Caregiving and disability-related stigma is gendered. The stigma of childhood disability is often associated with women's role in child bearing and rearing. Better engagement with fathers, and other key members of the family, is needed. Emotional distress, isolation and lack of support are common caregiver experiences in Ghana. A support group model for caregivers has an impact on how they feel about themselves, reducing levels of self-blame and feelings of isolation. We know that the quality of caregiving is really important in the early years of a child's development, so it is important to address any stigma. Factors, such as poverty, play a role in fuelling stigma. These other factors also need to be addressed if we want to reduce levels of stigma experienced by families.
Experience with Diversity is Not Enough: A Pedagogical Framework for Teacher Candidates that Centers Critical Race Consciousness

How to cite Lee, A. Y. , & Lee, A. J. (2020). Experience with diversity is not enough: A pedagogical framework for teacher candidates that centers critical race consciousness. Journal of Curriculum Studies Research, 2(2), 40-59. https://doi.org/10.46303/jcsr.2020. 9 ABSTRACT Given the overwhelming whiteness of teacher education, we offer a pedagogical approach rooted in critical race theory, and draw on notions of critical race consciousness to: 1) center a critical race perspective in methods-based coursework; and 2) employ critical race theory to analyze the function and role of clinical fieldwork. In this article, we provide examples of how we engage white teacher candidates to preemptively take stock of their own racial journey and biases prior to being responsible for educating students of color. We also focus on the process of selecting clinical placements and assignments. We explicate how current selection criteria for clinical sites and cooperating teachers are undergirded by systems of white supremacy, and problematize the reality of majority white clinical placements. We further provide suggestions for teacher education programs that pay particular attention to the roles and responsibilities of white teacher educators and predominantly white teacher education programs.
Structure-Aware Trail Bundling for Large DTI Datasets

Creating simplified visualizations of large 3D trail sets with limited occlusion and preservation of the main structures in the data is challenging. We address this challenge for the specific context of 3D fiber trails created by DTI tractography. For this, we propose to jointly simplify trails in both the geometric space (by extending and adapting an existing bundling method to handle 3D trails) and in the image space (by proposing several shading and rendering techniques). Our method can handle 3D datasets of hundreds of thousands of trails at interactive rate, has parameters for the most of which good preset values are given, and produces visualizations that have been found, in a small-scale user study involving five medical professionals, to be better in occlusion reduction, conveying the connectivity structure of the brain, and overall clarity than existing methods for the same data. We demonstrate our technique with several real-world public DTI datasets.
The experience of intergroup contact in primary-school ‘Shared Education’ classrooms: evidence from Northern Ireland

ABSTRACT The purpose of this paper is to explore the experiences of pupils and teachers within two primary school Shared Education partnerships in Northern Ireland; in particular, how intergroup contact is experienced within such contexts. A comparative, instrumental case study design was employed, which included document review, observation of Shared Education activities, interviews with school principals and teachers, and arts-based group interviews with children. While the paper supports existing research from secondary schools which suggests the potential of Shared Education to create spaces for building positive relations between pupils, the findings also highlighted several key issues which further extend understanding of Shared Education. Firstly, it emphasised the importance of planning, time and structure in Shared Education activity in order to dispel negativity and social awkwardness; secondly, it suggested the need for teachers to ‘model’ positive cross-group relations in their relationships between each other; and thirdly, it revealed a lack of clarity around how to deal with controversial issues as part of Shared Education activity. The paper concludes by suggesting that there is a need for additional guidance for schools around the intended aims and outcomes of Shared Education in relation to its potential to promote positive intergroup contact.
Review of Biometeorology of Heatwaves and Warm Extremes in Europe

Numerous extreme heatwaves producing large impacts on human health, agriculture, water resources, energy demand, regional economies, and forest ecosystems occurred during the first twenty years of the 21st century. The present study strives to provide a systematic review of recent studies of warm biometeorological extremes in Europe. The main aim of this paper is to provide a methodical summary of the observed changes in warm extremes, duration, and variability in different parts of Europe. During the last decade, much attention has been paid to the negative impacts of heat and humidity on human health. Therefore, the human biometeorology is required to appraise the human thermal environment in a way that human thermoregulation is taken into account. In many European countries and regions, future heat exposure will indeed exceed critical levels, and a steep increase in biometeorological heatwaves and warm extremes are expected. The indices that take into account human energy balance along with weather conditions should be used to examine the impacts of extreme heatwaves on human health and should be used as a basis for the determination of acclimatization to high-heat-stress conditions. A detailed description of recent studies that have used biometeorological indices such as Physiological Equivalent Temperature (PET) and Universal Thermal Climate Index (UTCI) for the estimation of warm extremes and their influence on human health is provided. Additionally, a short overview of the existence of the heat-health warning systems (HHWS), their conceptualization, and implementation across the European continent is considered, as well as the possibilities for further investigations and implementation of effective measures and programs that could reduce the adverse health impacts.
The Effect of Brand Perceptions on Repurchase When Using the E-commerce Website for Shopping

This study aims to investigate the influence of some critical factors (store/brand perceptions and trust in the web-store) on online repurchase intention. A pre-validated questionnaire was distributed to a convenience sample with response rate of 95.2% (n = 684) web-store buyers that were examined for assessing the research model. Primary data were collected during the period between December 2019 and February 2020, from respondents in Amman the capital of Jordan. Using AMOS 22.0 software, the collected data were analyzed with structural equation modeling (SEM). Confirmatory factory analysis (CFA) was used to estimate the measurement model with respect to convergent and discriminant validities. This was followed by testing the structural model framework and research hypotheses. The results showed that retailers can not only enhance trust in this store through robust brands, but also reap several benefits such as better brand image and demand. Thus, it has been found that the store as a brand could turn out to be as important that make it easier for customers to build trust, constituting a strong antecedent of behavioral intentions where behavioral intentions can lead to repurchase patterns. Unlike extant research, this model proposes store brand perception and product brand perception as determinants of intentions and trust in a web-store.
Medium-density fibreboard milling using selected technological parameters

The aim of this study was to investigate the effect of blade type and sharpness angle on blade wear, cutting power, and surface roughness. The study was conducted on medium-density fibreboard (MDF) panels. Two blade types were analyzed (high-speed steel and cemented carbides) along with three variants of sharpness angles (40°, 45°, and 55°). Machining operations were performed on a spindle moulder at a feed rate of 6.3 m/min and rotational speed of 4500 min-1. The blade wear criterion was adopted as the loss of cutter surface area measured on the rake face. Roughness was determined using the Ra parameter, which was measured at three points on the cross-section of the MDF panel. A new, multifaceted approach to the study of cutting a narrow surface of the MDF board was used, thanks to which the interaction of such parameters as blade wear, cutting power, and machining quality as well as the type of material of the knives and their angular parameters were determined. An increase in blade wear and cutting power was recorded with an increase in cutting path, while roughness at the MDF panel cross-section varied. The cemented carbides cutter with the 45° angle may be proposed as optimal, because it showed a relatively low wear and cutting power while providing good quality of the milled surface.
A 2000-year documentary record of levee breaches on the lower Yellow River and their relationship with climate changes and human activities

The Yellow River floodplain represents a fertile landmass that contributes significantly to human welfare and thus has been colloquially known as the birthplace of Chinese civilization. The sediment-laden nature of the Yellow River gave rise to a super-elevated channel belt, which is prone to failure particularly in the summer months when excessive precipitation occurs, resulting in cataclysmic floods traditionally regarded as “China’s Sorrow. ” Therefore, a deeper understanding of levee breach frequency in this area is especially important for the assessment of socio-economic risk of levee breaches associated with future climate changes. To better understand the nature, evolution, and driving mechanisms of levee breaches on the lower Yellow River, it is necessary to place the instrumental data within a longer time framework. Here, we retrieve past information about levee breaches on the lower Yellow River since AD 11 from various documentary sources such as official histories of China. We evaluated each line of descriptions and narratives about the location, timing, and nature of each event in these documents, ending up with a detailed timeline of levee breaches on the lower Yellow River during the last 2000 years on an annual time scale. Our results reveal remarkable variations in the frequency of levee breaches superimposed on a long-term increasing trend. In addition to climate changes, the iterative embankment-siltation-breaching process caused a feedback: more breaches result in much more channel siltation, which in turn leads to even more breaches. The enhanced farming in the Loess Plateau played a pivotal role in the formation and operation of this positive feedback. Our findings may not only help improve the assessment of socio-economic risk of levee breaches associated with future climate changes, but also provide consulting information for hydraulic engineering and infrastructural designs in the lower Yellow river area.
Experimental Research and Numerical Analysis of Flow Phenomena in Discharge Object with Siphon

This article presents results of the experimental research and numerical simulations of the flow in a pumping system’s discharge object with the welded siphon. The laboratory simplified model was used in the study. Two stationary flow regimes characterized by different volume flow rates and water level heights have been chosen. The study concentrates mainly on the regions below and behind the siphon outlet. The mathematical modelling using advanced turbulence models has been performed. The free-surface flow has been carried out by means of the volume-of-fluid method. The experimental results obtained by the particle image velocimetry method have been used for the mathematical model validation. The evolution and interactions of main flow structures are analyzed using visualizations and the spectral analysis. The presented results show a good agreement of the measured and calculated complex flow topology and give a deep insight into the flow structures below and behind the siphon outlet. The presented methodology and results can increase the applicability and reliability of the numerical tools used for the design of the pump and turbine stations and their optimization with respect to the efficiency, lifetime and environmental demands.
