FACTORS INFLUENCING THE INTENTION TO USE COMPUTER TECHNOLOGY FOR E-LEARNING AMONG UNIVERSITY STUDENTS

The utilisation of gadgets and computer technology has become a significant aspect of e-learning. This condition requires students to use various online platforms for learning purposes. The current study aims to explore the potential factor in explaining the intention to use computer technology during e-learning among private university students. Online questionnaires were distributed to 174 university students from various programmes in a university in Selangor. The items in the questionnaire covered three independent variables: perceived ease of use of technology, perceived usefulness of technology, and computer self-efficacy. The dependent variable is the intention to use computer technology in e-learning. Pearson Correlation was used to assess the relationship between the independent and dependent variables. Furthermore, Hierarchal Multiple Regression analysis was used to determine the predictor of the intention to use computer technology. The result showed that the intention to use computer technology for e-learning was significantly related to technology’s perceived ease of use, usefulness, and computer self-efficacy. However, when computer self-efficacy is controlled, students’ intention to use computer technology is driven by their perceived notion that technology is easy to use and usefulness of the technology. The study concludes that when students perceive technology as easy to use and sense its practicality, they will have a stronger intention of using technology for learning. This research implies that a systematic strategy should be practised by integrating computer technology into teaching and learning in the current situation. Future studies could further explore the potential of differences across students’ backgrounds towards e-learning.

The model structure and some preliminary results are discribed showing that the new modelling approach appears to deliver satisfactory results in terms of accuracy, reliability and robustness. It is believed that model performance can be further improved by exploring various other options. It is also important to examine the performance of other model structures (e.g. simpler or more complex models) and further examine the interactions between availability and quality of input data, level of model detail and overall prediction accuracy.
Effectiveness of technology in Open Distance Learning

Technology was gradually embraced by distance education institutions to interact and instruct their diverse student body. To reach students in far-flung locations, the University of South Africa (Unisa) has embraced the Open Distance and E-learning (ODeL) paradigm. The digital gap is a problem as technology advances because it makes it difficult for pupils to access the Internet. The study went over the literature with a particular emphasis on the usefulness of technology in ODeL. To thoroughly examine the case, the study has chosen a qualitative research methodology. To analyze the data acquired from students enrolled in ODeL courses, the study has utilized a community of inquiry structure. The study made use of the interpretative paradigm, which holds that reality is a multi-layered, complicated phenomena that may be interpreted in several ways. The study is comprehensive in character since a qualitative research technique using a case study design method was chosen most appropriate for it. Twelve individuals were chosen by the researchers from two Unisa regional offices in the Eastern Cape Province using a purposive sample technique. The participants were questioned about their opinions and experiences with using technology during semi-structured interviews. Thematic analysis, a method of finding themes within qualitative data, was used to analyze the acquired data. The results showed that students who used technology well were better communicators, had better grades on their assignments, and fared well on tests
Kikuchi Disease Unveiling Systemic Lupus Erythematous: A Rare Case of Initial Manifestation

Background: Kikuchi disease is a rare presentation, which typically presents with cervical lymphadenopathy and fever. Its association with Systemic Lupus Erythematous (SLE) is well established, although majority of SLE cases does not present with Kikuchi disease. We report a case, in which a young patient presented with fever and cervical lymphadenopathies for two weeks duration. This carries a broad differential and initially raising the possibility of infections or malignancies. However, after further clinical evaluation including cervical node biopsy, direct histological examination revealed Kikuchi disease. Combining all clinical information and laboratory data, we concluded that the patient’s condition was consistent with Kikuchi disease associated with SLE with probable autoimmune hepatitis (AIH). This case illustrates a young female patient with clinical presentations of SLE associated with Kikuchi disease as first manifestation.

Structures, Antioxidant Properties, and Antimicrobial Properties of Eu(III), Gd(III), and Dy(III) Caffeinates and p-Coumarates

In this study, we investigated the structures of lanthanide (Eu(III), Dy(III), and Gd(III)) complexes with p-coumaric (p-CAH2) and caffeic (CFAH3) acids using the FTIRKBr, FTIRATR, and Raman spectroscopic methods. The compositions of the solid phase caffeinates and p-coumarates were obtained on the basis of the amounts of hydrogen and carbon determined using an elemental analysis. The degree of hydration and the thermal decomposition of each compound were examined via a thermal analysis of TG, DTG, and DSC. Antioxidant spectroscopic tests were performed using the DPPH (1,1-diphenyl-2-picrylhydrazyl radical), FRAP (ferric reducing antioxidant activity), and ABTS (2,2’-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (diammonium salt radical cation) methods. The antimicrobial activity of each compound against Escherichia coli, Bacillus subtilis, and Candida albicans was investigated. The electrical properties of the liposomes which mimicked the microbial surfaces formed in the electrolyte containing the tested compounds were also investigated. The above biological properties of the obtained complexes were compared with the activities of p-CAH2 and CFAH3. The obtained data suggest that lanthanide complexes are much more thermally stable and have higher antimicrobial and antioxidant properties than the ligands (with the exception of CFAH3 in the case of antioxidant activity tests). The Gd(III) complexes revealed the highest biological activity among the studied lanthanide complexes.
East vs West: Satisfaction With Knowledge Sharing Among Millennials

Knowledge sharing (KS) among individuals working together is complex and has an effect on their satisfaction. We adopt the self-determination theory and the theory of reasoned action to examine the relationship between millennials’ characteristics, KS and the resulting satisfaction. Using a mixed-method approach we address the antecedents of satisfaction in KS for 213 millennials attending Master programs in management at Polish and Portuguese business schools. The quantitative results show that knowledge characteristics influence KS as well as the fear of losing power due to KS. Knowledge complementarity and knowledge complexity positively contribute to KS. Knowledge complexity increases the fear of losing power due to KS, while knowledge complementarity decreases it, probably because individuals recognize complex knowledge as a more valuable one. The qualitative findings corroborate the quantitative results. Knowledge complementarity’s presence alone leads to KS, while its absence and knowledge complexity’s existence generate the fear of losing power. KS behavior and not being afraid of losing power due to KS lead to satisfaction from KS. The integration of both outputs is robust since quantitative results and qualitative findings converge: a) KS results from knowledge complementarity: knowledge complementarity relates positively to KS, which is consistent with a high level of knowledge complementarity providing a sufficient condition for a high level of KS; b) The fear of losing power results from the absence of knowledge complementarity and the existence of knowledge complexity, which is consistent with knowledge complementarity relating negatively to the fear of losing power and knowledge complexity relating positively to the fear of losing power; c) Satisfaction occurs when KS exists and the fear of losing power is absent, which is in line with KS relating positively to satisfaction and the fear of losing power due to KS relating negatively to satisfaction. Furthermore, the results show that millennial students’ satisfaction from KS is really a behavioral question and not a cultural one since there is no evidence of significant differences between the two subsamples. Millennials behave uniformly on Europe’s western and eastern ends.
Mindful Eating is More Effective to Beat Emotional Eating than Nutrition Education and Diet: A Randomized Controlled Study

Purpose: Mindful eating have a potential in addressing problematic eating behaviors and focusing the challenges often faced in food consumption. In this study, we conducted a randomized controlled trial that incorporated both mindful eating, including nutritional education with an energy-restricted diet. The aim is to contribute to the literature by revealing the comparative effectiveness of these approaches in alleviating problematic eating behaviors. Methods: This prospective randomized controlled study was conducted between January-April 2021 with 70 participants without chronic disease. Our study was approved by Ethics Committee of the Acibadem Mehmet Ali Aydinlar University. A questionnaire form that examined demographic data and Mindful Eating Questionnaire (MEQ-30), Turkish Emotional Appetite Questionnaire (TEAQ) were applied as pre-test and post-test of the interventions. Interventions were conducted in the groups as diet and education groups, also with control group. Anthropometric variables were reported by participants. Results: Mean age of our participants was 33.40±12.27 years. Participant who had the education compared to the diet and control groups, had higher scores in physical activity (p
A novel model based on necroptosis to assess progression for polycystic ovary syndrome and identification of potential therapeutic drugs

Background Polycystic ovary syndrome (PCOS), a common endocrine and reproductive disorder, lacks precise diagnostic strategies. Necroptosis was found to be crucial in reproductive and endocrine disorders, but its function in PCOS remains unclear. We aimed to identify differentially diagnostic genes for necroptosis (NDDGs), construct a diagnostic model to assess the progression of PCOS and explore the potential therapeutic drugs. Methods Gene expression datasets were combined with weighted gene co-expression network analysis (WGCNA) and necroptosis gene sets to screen the differentially expressed genes for PCOS. Least absolute shrinkage and selection operator (LASSO) regression analysis was used to construct a necroptosis-related gene signatures. Independent risk analyses were performed using nomograms. Pathway enrichment of NDDGs was conducted with the GeneMANIA database and gene set enrichment analysis (GSEA). Immune microenvironment analysis was estimated based on ssGSEA algorithm analysis. The Comparative Toxicogenomics Database (CTD) was used to explore potential therapeutic drugs for NDDGs. The expression of NDDGs was validated in GSE84958, mouse model and clinical samples. Results Four necroptosis-related signature genes, IL33, TNFSF10, BCL2 and PYGM, were identified to define necroptosis for PCOS. The areas under curve (AUC) of receiver operating characteristic curve (ROC) for training set and validation in diagnostic risk model were 0.940 and 0.788, respectively. Enrichment analysis showed that NDDGs were enriched in immune-related signaling pathways such as B cells, T cells, and natural killer cells. Immune microenvironment analysis revealed that NDDGs were significantly correlated with 13 markedly different immune cells. A nomogram was constructed based on features that would benefit patients clinically. Several compounds, such as resveratrol, tretinoin, quercetin, curcumin, etc., were mined as therapeutic drugs for PCOS. The expression of the NDDGs in the validated set, animal model and clinical samples was consistent with the results of the training sets. Conclusion In this study, 4 NDDGs were identified to be highly effective in assessing the progression and prognosis of PCOS and exploring potential targets for PCOS treatment.
Alfaisal University's Academic Success Center: An Individualized Peer-Assisted Learning Program for Mutual Tutor-Student Advancement

Introduction: Peer-assisted learning (PAL) is an educational strategy whereby students teach other students. PAL presents many advantages to the institution, tutors, and tutees. It can benefit the university by presenting a cost-effective approach where the efforts and time of faculty are reduced. We describe a retrospective analysis detailing the structure, function, and effectiveness of the Academic Success Center (ASC) at Alfaisal University, Riyadh, Saudi Arabia, since 2020. The ASC encompasses various types of PAL methods. It is the only PAL program in Saudi Arabia whereby its tutors, referred to as student consultants, are compensated financially. Methods: We retrospectively analyzed the total number of appointments, the total number of students who accessed the center, as well as the breakdown between different colleges and academic years, and their satisfaction level with the PAL mode of teaching. Results: Our results indicate a high level of appointments for these PAL sessions increasing on a yearly basis and a high level of satisfaction from both the tutors and the tutees. Conclusion: PAL is an effective teaching and mentoring modality with high retention rates that has contributed to an increased sense of well-being among students who have utilized these services.
Geochronological constraints on the Paleozoic to Early Mesozoic geodynamic evolution of southern coastal Peru

The main objective of this dissertation was to establish a chronostratigraphic framework for the south Peruvian margin for the late Paleozoic to Mesozoic based on geochronological, geochemical and isotopic data on periods of magmatism and magmatic quiescence along the western Gondwana margin since the onset of subduction around 530 Ma ago. Our integrated geochronological study, revising the information of sedimentary basins and magmatism in southern coastal Peru (15-18°S) provide new insights in the evolution of this segment of the western Gondwana margin since the onset of subduction.
European droughts under climate change : projections and uncertainties

Droughts are one of the most damaging natural hazards, and anthropogenic climate change has and will continue to alter their characteristics. Better understanding of changes in drought characteristics under potential future climates is vital for managing drought risks and impacts, yet projections are very uncertain. This thesis examines the effects of climate change on European drought characteristics through a multi-scenario and multimodel approach. It explores the uncertainty associated with emission scenarios, global and spatial climate projections, and with the identification and characterisation of droughts. Climate projections simulated by the simple climate model MAGICC6.0 and patternscaling climate scenario generator ClimGen are assessed, emulating eighteen CMIP3 general circulation models (GCMs) under ten emission scenarios. Drought severity (magnitude times duration) and spatial extent are analysed for both 3-month and 12-month events. Drought projections vary substantially depending on the GCM, emission scenario, region, season and definition of drought. Overall, climate change enhances drought conditions across the study region, with marked increases simulated for the southern latitudes; reductions are projected for the northern latitudes, especially in winter and spring. Perturbations in the interannual variability of precipitation tend to enhance drought conditions caused by mean precipitation changes, or to moderate or reverse their reductions. Hydrological drought parameters are highly sensitive to potential evapotranspiration (PET), which shows the importance of the PET calculation method. Greater agreement in the direction of change tends to occur in the high- and low-latitudes, and in summer and autumn. Both meteorological and hydrological drought results generally indicate the same direction of change, with the latter having larger magnitudes. Projection ranges tend to increase with time and magnitude of warming; intra-GCM spread dominates other sources of uncertainty. The implications of the large uncertainties include that decision-making should be based on multi-scenario and multi-model results, and with consideration of drought definition.
Natural and anthropogenic carbon input affect microbial activity in salt marsh sediment

Salt marshes are dynamic, highly productive ecosystems positioned at the interface between terrestrial and marine systems. They are exposed to large quantities of both natural and anthropogenic carbon input, and their diverse sediment-hosted microbial communities play key roles in carbon cycling and remineralization. To better understand the effects of natural and anthropogenic carbon on sediment microbial ecology, several sediment cores were collected from Little Sippewissett Salt Marsh (LSSM) on Cape Cod, MA, USA and incubated with either Spartina alterniflora cordgrass or diesel fuel. Resulting shifts in microbial diversity and activity were assessed via bioorthogonal non-canonical amino acid tagging (BONCAT) combined with fluorescence-activated cell sorting (FACS) and 16S rRNA gene amplicon sequencing. Both Spartina and diesel amendments resulted in initial decreases of microbial diversity as well as clear, community-wide shifts in metabolic activity. Multi-stage degradative frameworks shaped by fermentation were inferred based on anabolically active lineages. In particular, the metabolically versatile Marinifilaceae were prominent under both treatments, as were the sulfate-reducing Desulfovibrionaceae, which may be attributable to their ability to utilize diverse forms of carbon under nutrient limited conditions. By identifying lineages most directly involved in the early stages of carbon processing, we offer potential targets for indicator species to assess ecosystem health and highlight key players for selective promotion of bioremediation or carbon sequestration pathways.
Oxygen saturation targets for children with respiratory distress: a systematic review

Background In children with respiratory distress, supplemental oxygen is indicated at peripheral oxygen saturation (SpO2) thresholds of 90–94%. However, these thresholds are poorly studied. We conducted a systematic review to summarise the existing evidence for SpO2 thresholds in children with respiratory distress. Methods Electronic databases and registries were searched for original articles published from 1 January 2010 to 7 January 2022 comparing two or more SpO2 thresholds in children with respiratory distress. Primary outcomes were safety, including mortality, neurocognitive outcomes and readmissions, and effectiveness, including admission rate and length of hospital stay. Methodological appraisal was performed using the Cochrane Risk of Bias 2 (RoB-2) or Risk of Bias in Non-Randomized Studies – of Interventions (ROBINS-I) tools. Results were narratively synthesised. Results We retrieved 3384 results; seven studies were included. Lower thresholds ranged from 80% to 92% and were compared with higher thresholds ranging from 92% to 94%. Studies were highly heterogeneous in setting, design, population and outcomes. Risk of bias varied from low to high. Lower SpO2 thresholds had equivalent mortality, neurocognitive outcomes and readmissions or re-attendance to healthcare to higher thresholds. Lower SpO2 thresholds showed a significant decrease in admission rates by up to 40% and shortened hospitalisation duration by 10–18 h. Conclusions The current SpO2 thresholds of 90–94% in children with respiratory distress may be too high, which could lead to unnecessary hospitalisations and prolonged hospitalisation duration. SpO2 thresholds as low as 88% are potentially safe in children with respiratory distress and may reduce hospitalisation rates and length of stay. However, high-quality evidence is needed to support this. Tweetable abstract Current SpO2 thresholds of 90–94% for children with respiratory distress may be too high, as lower SpO2 thresholds have equivalent safety outcomes and better effectiveness. An SpO2 threshold of 88% is potentially safe, but further research is required. https://bit.ly/3YAE6q8
