Understanding Student Acceptance of Online Learning Systems in Higher Education: Application of Social Psychology Theories with Consideration of User Innovativeness

The COVID-19 pandemic has created the opportunity to conduct a huge experiment with online classes in the university setting. The objectives of this study are (1) to provide obvious insight into determining factors driving greater intention of students to use online learning systems based on an integrated technology acceptance model (TAM) and theory of planned behavior (TPB), and (2) to provide the moderating role of innovativeness as a key factor. An online survey was conducted with 216 university students taking hospitality and tourism studies in Busan, Korea. The results of the study are as follows. First, perceived ease of use affects perceived usefulness, perceived usefulness affects attitude, whereas perceived ease of use does not directly affect attitude. Second, attitude and subjective norms positively influence behavioral intention, while perceived behavioral control does not. Third, user innovativeness plays a moderating role in the relationship between subjective norms and behavioral intention. As part of the lessons learned from COVID-19, it is meaningful to provide insightful implications to academia, specifically to the college of hospitality and tourism.
Functionalised graphene effect on the mechanical and thermal properties of recycled PA6/PA6,6 blends

Limiting the generation of polymers waste and maximizing their recyclability and recovery have been the main focus of the research and industry in recent years. Recycling of polyamides leads to the loss in mechanical and thermal properties, therefore, in order to reuse recycled nylons, an enhancement in their properties is desired. Enhancing the properties of recycled polyamides by the addition of functionalised graphene nanoparticles (GNPs) was the goal of this study. Recycled PA6/PA6,6 blends and functionalised graphene nanocomposites were prepared using hot-melt extrusion process. Two types of functionalised graphene were used: O2-GNPs and Amine-GNPs. The nanofillers didn’t affect the crystallinity of the recycled nylon, while the presence of functionalised graphene increased the thermal conductivity by enabling better heat transfer routes within the polymer. The microstructure of the materials was characterised confirming the successful dispersion but with a slight variation in GNPs/Polymer bonding depending on the functionalisation type. The strong nylon-to-graphene interfacial hydrogen bonding increased the mechanical properties of the recycled nylon nanocomposites. The functionalised nanoparticles slowed down the segmental motion of the polymer chain and decreased the ductility with increasing GNPs contents up to 10 wt%. The overall behaviour of recycled nylon nanocomposites showed dependency on the type of functionalisation and concentration of GNPs with better improvement in the overall properties using 2 wt% Amine-GNPs. These enhanced properties make functionalised graphene/recycled nylon nanocomposites a promising new class of advanced materials.
Integration of DFMA and sustainability - A case study

ABSTRACT In recent days, incorporation of sustainability principles in product design is gaining importance to survive and compete in the market. The goal of this work is to simultaneously apply the DFMA and sustainability principles in product design. For this purpose, a bike horn is chosen as a candidate product. The three dimensional model of an existing bike horn is created in a modelling package. The DFMA principles are applied to reduce the number of parts, cost of materials, manufacturing processes and the assembly time. The number of parts and total cost were reduced by 22.92 and 24.59%, respectively. The sustainability concepts are then applied on the product with a view to reduce its impact on the environment. It was found that, the carbon footprint and the total energy consumed were reduced by 13.04 and 8.69%, respectively. Thus, the integrated application of DFMA and sustainability concepts results in not only economical product but also eco-friendly one.
Pre-Clerkship Medical Students’ Experiences and Perspectives of System 1 and System 2 Thinking: A Qualitative Study

Dual-process theories may be invoked to explain how physicians interact with, interpret, and draw inferences from clinical information. Stanovich and West’s model articulates two kinds of thinking—intuitive-based System 1 and analytical-based System 2—which have been under-investigated with physicians in training. This qualitative study explored pre-clerkship medical students’ retrospective perspectives and experiences of System 1 and System 2 thinking via 12 semi-structured interviews and abductive, progressive focusing. Participants identified patient interactions, clinical note writing, knowledge synthesis, problem list and differential diagnosis generation, evaluating evidence, and critical appraisal of literature as pre-clerkship opportunities to engage in System 1 or System 2 thinking. Six major themes emerged from analysis of participants’ interview transcripts: cognitive processes, deliberate practice, learning environment: being alone or being together, stickiness factor, biases and heuristics, and prior experience of attaining competence. Participants valued the anticipated role that System 1 and System 2 thinking will play in their future practice, and experienced nascent, self-regulated development of these cognitive processes during the pre-clerkship phase of their education without formal feedback or coaching from clinician preceptors. Pre-clerkship curricula should further embrace low-stakes, incremental teaching on metacognition and continuous monitoring of knowledge processing as a key competency for physician learners.
Playing to heal: The impact of bereavement camp for children with grief.

Child bereavement is a difficult topic to explore and study because of stigmas in discussing death, and because of restrictions in doing research with young children. Thus, research in childhood bereavement is limited. This study focused on children who attended a bereavement camp after the traumatic loss of a loved one. The purpose was to understand the participants’ grief experiences. This research study used phenomenological inquiry and analysis methodology. Five female participants were interviewed for this study. In addition, participants created a sandtray world to convey their experiences at bereavement camp. The essence of participants’ experiences as revealed through verbal interviews was posttraumatic growth. In addition, the essence of participants’ experiences as revealed through their sandtray worlds was gaining a sense of support. Results of this study extend bereavement research to include the experiences of children. Further, implications for mental health professionals, counselor educators, and bereavement camps are emphasized.
Self-efficacy in creativity and curiosity as predicting creative emotions

Self-efficacy constructs could predict students’ practices and affect in learning the sciences. Researchers have pointed at such constructs as predictors of students’ mathematics achievement and performance. Self-efficacy was also studied as predictor of emotions in learning mathematics, though little research has done so regarding self-efficacy as predictor of creative emotions. Another predictor of creative emotions could be curiosity. The present study has a regression-based modelling design, where it examined whether a set of constructs of self-efficacy in creativity or/and a set of constructs of curiosity predict significantly creative emotions in mathematical problem solving. Five hundred Grade 8-10 students participated in the study. Data were collected using three self-report questionnaires that measured the research constructs. Data analysis used SPSS 21. Results from multiple regression indicated that the set of constructs of self-efficacy in creativity explained significantly 29.6% of the variance in creative emotions. Moreover, the set of constructs of curiosity explained 17.8% of the variance in creative emotions. Furthermore, three of the five independent variables had best prediction of creative emotions, explaining 32.9% of the variance in creative emotions. The results of the stepwise regression showed that self-efficacy in originality and stretching curiosity were the first two variables in a set of three variables that best explained the variance in creative emotions. The research results lead to the recommendation of developing the previous two constructs in classroom setting to cultivate students’ creative emotions and thus their creative practices.
Predictive Value of Cerebrospinal Fluid Biomarkers for Tap Test Responsiveness in Patients With Suspected Idiopathic Normal Pressure Hydrocephalus

Background: The value of cerebrospinal fluid (CSF) biomarkers for assessing idiopathic normal pressure hydrocephalus (iNPH) must be determined. This prospective study aimed to reveal the correlation between CSF biomarkers and clinical symptoms of iNPH and the predictive value of these biomarkers for tap test responsiveness. Methods: Thirty-nine patients with suspected iNPH were recruited, contributed qualified CSF, and underwent a tap test and unified pre- and post-test evaluations of the neurological function. Results: The analysis of biomarkers from the patients’ CSF showed decreased levels of tau and its phosphorylated form, especially in the tap test (+) group. The responsiveness of the tap test was also related to the number of combined symptoms (p < 0.01), and a correlation was found between the end pressure or pressure difference in CSF and tap test responsiveness (p < 0.05). The results of the binary logistic regression analysis showed that P (tap test responsiveness) = 1/1 + e∧ − (−5.505 + 55.314 * ratio of p/T-tau − 1.586 * numbers of combined symptoms). The combined indicators (−5.505 + 0.553 * percentage of p/T-tau − 1.586 * numbers of combined symptoms) resulted in the highest sensitivity and specificity of 94.12% and 72.73%, respectively. Conclusions: CSF biomarkers may be assessed to judge tap test responsiveness, which is beneficial for the feasibility of a clinical application.
What Constitutes Good Quality End‐of‐Life Care? Perspectives of People With Intellectual Disabilities and Their Families

Background: Due to increased life expectancy, just as with the general population, people with intellectual disabilities are experiencing, and dying from, chronic and life-limiting conditions. This has led to an increase in the need for end-of-life care for people with intellectual disabilities. However, there is limited evidence as to what constitutes good end-of-life care from the perspectives of people with intellectual disabilities and their family members. Methods: The study reported here aimed to find out the care needs of people with intellectual disabilities at the end of life in Ireland. A grounded theory approach was employed to explore the perspectives of the participants. After obtaining appropriate ethical approval, 19 semi-structured individual interviews were carried out with 11 people with mild and moderate intellectual disabilities and eight family members to collect data which was subsequently analyzed through constant comparative analysis. Results: The views of the participants suggested that providing personal care while vulnerable and dying, being with and communicating with the dying person, and meeting their spiritual needs, were considered as being essential at the end of life for people with intellectual disabilities. Conclusion: The findings from this study have shown that people with intellectual disabilities can engage with those around them and demonstrate how they would like to be cared for, and discuss what would be considered as being good care at the end of life.
The biocompatibility of Achyrocline satureioides plant extract over human gingival fibroblasts

Objective: Achyrocline satureioides “A.satureioides” is a subshrub, widely distributed in South America because of its medicinal properties. Although it is widely used in folk medicine, there is still no approval for its therapeutic use, and its biocompatibility is little explored. This study aimed to evaluate its cytotoxicity and genotoxicity over human gingival fibroblasts (FMM-1). Methodology: Ten different concentration of the glycolic extract of A.satureioides were tested for 5min and 24h of contact with the cells to evaluate its cytotoxicity using the MTT colorimetric assay and to evaluate its genotoxicity using the micronucleus assay. Data were analyzed with one-way ANOVA and Tukey test with a significance level (α=0.05). Results: All tested concentrations of the extract presented cell viability more than 70% and has no significant difference of the control group after 5min and 24h. However, for 5min the 100 mg/mL was cytotoxic and for 24h the 1.56 mg/mL stimulated cell proliferation. For genotoxicity analysis, only the concentration 6.25 mg/mL showed results similar to the control of cell culture in the micronucleus count after 5min and 24h. Conclusions: The glycolic extract of A.satureioides doesn’t have cytotoxic and genotoxic effects in concentrations up to 6.25 mg/mL, but in high concentrations it is considered genotoxic.
Tropical Cyclones in Global Storm-Resolving Models

Recent progress in computing and model development has initiated the era of global storm-resolving modeling, and with it the potential to transform weather and climate prediction. Within the general theme of vetting this new class of models, the present study evaluates nine global-storm resolving models in their ability to simulate tropical cyclones (TCs). Results indicate that, broadly speaking, the models produce realistic TCs and remove longstanding issues known from global models such as the deficiency in accurately simulating TC intensity. However, TCs are strongly affected by model formulation, and all models suffer from unique biases regarding the number of TCs, intensity, size, and structure. Some models simulated TCs better than others, but no single model was superior in every way. The overall results indicate that global storm-resolving models can open a new chapter in TC prediction, but they need to be improved to unleash their full potential.
An integrated-multi-RAT framework for multipath-computing in heterogeneous-wireless network

ABSTRACT The bandwidth-intensive applications on Smart-Mobile-Devices (SMDs) are increasing with SMD's colossal growth. The overlapped cellular and non-cellular networks, in hot-spot-places, and SMDs capabilities are significant reasons for this growth. SMD's interfaces-RAT (Radio-Access-Technology) can have complementary link characteristics. The end-users can avail always-best-connectivity (ABC) on their SMDs with complementary RAT characteristics. This paper proposes an Integrated-multi-RAT-utilization (Im-Ru) framework for multipath-computing support to realize ABC for the end-users. The Im-Ru framework has two approaches. The First is a hybrid-RAT-discovery model based on SMD's interfaces, current-location, and identification using ANDSF and MIIS servers. The second is the user's preference-based RAT-selection using weighted-RAT-parameters. We observe that the Im-Ru framework for multipath-computing is useful in future 5G-NR networks. We analyzed the Im-Ru's performance related to average-throughput improvement over the existing approaches for SMD's different speeds and observed a significant improvement. The experimental results show that Im-Ru is more reliable by realizing lower packet-loss and delay than existing work.
Negotiating languages of suffering in northern Uganda

Drawing on ethnographic fieldwork in northern Uganda, I argue that psychiatric notions of suffering brought into the region by humanitarian intervention programs interact with local concepts of suffering (based in spirit-idioms) in two ways: In some cases, the diagnostic notion of PTSD and its vernacular counterpart “trauma” psychologize the local cosmology, transforming local spirit concepts from social or moral categories, to psychological ones. In other cases, psychiatric discourses hinged around “trauma” become spiritualized or enchanted, where the concept of trauma becomes usurped by and part of local cosmology. In an attempt to understand these processes, I suggest understanding concepts of suffering through their use in social practice and based on pragmatist epistemology. If viewed as a pragmatist concepts, I argue, it becomes possible to understand the social life of concepts of suffering (such as “trauma”) when they become globalized and negotiated in new contexts and social practices.
Cognitive, affective, and global attitude toward physical activity with different intensities

ABSTRACT Objectives: The purposes of this study were to determine the differences of college students' attitudes toward physical activity (PA) with different intensities and the contributions of students' cognitive and affective attitude to their global attitude toward PA. Design: This study employed a cross-sectional design. A total of 159 college students completed validated measures of global, cognitive, and affective attitude for general, vigorous, moderate, and light PA, respectively. Repeated-measure one-way ANOVAs were conducted to determine the differences of students' attitude toward PA with different intensities. Multiple regression analyses were conducted to determine the contributions of cognitive and affective attitude to global attitude for each type of PA. Results: Students had significantly higher levels of cognitive attitude toward moderate PA than vigorous and light PA. They had significantly higher levels of affective attitude toward light PA than moderate and vigorous PA and higher levels of affective attitude toward moderate PA than vigorous PA. They also had significantly lower levels of global attitude toward vigorous PA than light and moderate PA. This study also showed that both cognitive and affective attitude contributed to global attitude and cognitive attitude had a stronger influence than affective attitude. Conclusions: College students tend to have different levels of cognitive, affective, and global attitude toward PA with different intensities. Interventions targeting at cognitive beliefs about PA may be more effective to change college students' attitude toward PA than targeting at feeling or emotions attached to PA.
A Proposed Program to Improve Quality of life for the Orphans at Social Care Homes

The present paper investigates the reality of services and quality of life of orphans, identifies the relationship between both variables, and proposes a program to improve the quality of life among the orphans at social care homes. The author developed and applied a questionnaire of the reality of services provided and a scale of quality of life to (100) orphans at social care homes in Riyadh, Saudi Arabia. The results showed low levels of services and quality of life among the orphans at social care homes. There was a positive correlation between those services and the quality of life among orphans. The paper recommends the adoption of the proposed program by decision-makers and specialists in the care and rehabilitation of the orphans to improve their quality of life. Moreover, the program should be an integral part of rehabilitation and education programs delivered to the orphans in the future.

Assessment of Rapid Diagnostic Tests Algorithms in Transfusion Medicine Setting

Background: The rapid diagnostic tests play a pivotal role in the screening of viral markers in blood qualification for transfusion in limited resource setting. Therefore, it is important to assess their analytical performances to ensure their proper functioning. Material and Methods: We performed a cross- sectional study by successive recruitment to assess the diagnostic value of rapid diagnostic tests algorithms using ELISA as a reference test. A total of 661 blood from donors were enrolled for this study. Rapid Diagnostic Tests (RDTs) and ELISA tests were performed for each sample by a couple of double-blinded biotechnologists. Data were collected on case report form and captured in Microsoft Excel then the file was imported and analyzed using R software version 4.0. 3. Results: The diagnostic accuracy for the algorithms are summarized in Table 1. For HIV-algorithm, the internal validity parameters were as follow: sensitivity (sens) 99.0% (95% CI = 97.8, 99.5); specificity (spec) 98.3% (95% CI = 90.9, 99.7); positive likelihood ratio (PLR) 57.4 (95% CI = 8.2, 401.0); negative likelihood ratio (NLR) 0.01 (95% CI = 0.0005, 0.02); diagnostic odd ratio (DOR) 4710. HBV-Ag/Ab RDTs achieve the following diagnostic accuracy: sens 99.7% (95% CI = 98.3, 99.9); spec 98.8% (95% CI = 96.9, 95.5); PLR 81.8 (95% CI = 30.9, 217.0); NLR 0.003 (95% CI = 0.0004, 0.02); DOR 14,110. The analytical performances of HCV-Ab RDTs were as follow: sens 98.7% (95% CI = 97.5, 99.4); spec 93.1% (95% CI = 78.0, 98.1); PLR 14.3 (95% CI = 3.8, 54.5); NLR 1.5 (95% CI = 0.8, 2.8); DOR 962.6. The parameters evaluating the external validity of RDTs screening for the three viral markers when the theorical prevalence was 5% are summarized in Figure 3. At the prevalence , 99.99% and 99.94%. At the same prevalence, we found the following Positive Predictive Values (PPV) 70.82%, 77.59% and 37.35% for HIV-Ag/Ab RDTs, HBV-Ag RDTs and HCV-Ab RDTs algorithms, respectively. The overall areas under the received operating characteristic (ROC) curves were 98.6%, 99.2% and 99.2%; 95.9% for HIV-Ag/Ab RDTs, HBV-Ag RDTs and HCV-Ab RDTs algorithms, respectively. Conclusion: RDTs algorithms can play a pivotal role in the screening of HIV-Ab/Ag, HBs-Ag in the setting of resources limited-countries where financial and technical expertise shortages are a standard fare. However, their use for diagnostic purposes must be done with great caution and the result must necessarily be confirmed with an ELISA or molecular technique particularly for HCV-RDTs algorithm which achieved an NLR value > 0.1.
Analysis of the differences in serve effectiveness between Billie Jean King Cup (former Fed Cup) and Davis Cup doubles tennis matches

The doubles game has considerable relevance in professional tennis, especially in team competitions such as the Billie Jean King Cup (former Fed Cup) (BJKC) and the Davis Cup (DC). However, there are very few studies that have carried out quantitative notational analysis to provide information on the specific features of this tennis modality. The goal of this study was to analyse the differences in serve direction and effectiveness of male and female teams in matches played at BJKC and DC ties. A total of 29,207 serves; 7,578 of BJKC and 21,628 of DC matches were analysed. The data was obtained through the Hawk-Eye system. The results showed that with the first serve, both BJKC and DC teams tried to move the receiver by serving to zones W (wide) and T to take the initiative of the point, while with the second serve teams took lower risks and mainly served to zone B (body). In general, in DC matches the effectiveness of the serve was greater than in BJKC ones. The first serve effectiveness in DC matches was found to be higher in each direction, while the differences in the effectiveness of the second serve was only found in the zone C (body) of the advantage service box. This information can be particularly relevant for coaches to design the doubles training sessions and the strategic planning of doubles matches on reliable and quantitative information.
