Replicating “Language Matters”: Taking Baselines into Account

Abstract This study evaluates the visibility of French-speaking scholars in Canadian political science by analyzing the reading materials assigned in Canadian politics courses. Extending Daoust et al.'s (2022) research, we establish a baseline for their calculations and build an original dataset gathered from all political science departments’ websites and Google Scholar. Our analysis based on three assumptions about the expected academic representation of francophones—Canada's linguistic composition, the makeup of political science departments and faculty members’ productivity—reveals a discrepancy favouring anglophone scholars by up to four percentage points. Our findings extend Daoust et al.'s (2022) contribution by highlighting a similar language-based bias in overall citation practices among Canadian scholars, with French-speaking authors being significantly under-cited compared to their English-speaking counterparts despite demonstrating higher levels of overall productivity. Implications for the future of the discipline are also discussed.

The Level of Perceived Stress and Affecting Factors due to Current Economic Crisis Among Undergraduates in Faculty of Health-Care Sciences, Eastern University Sri Lanka

Abstract In 2021, the Sri Lankan government officially declared the worst economic crisis in the country. The ongoing economic crisis in Sri Lanka has been affecting the whole sector of the country. The undergraduate students who stayed in hostels had to suffer a lot due to restrictions of family income. The parents face difficulties in affording all expenses required by their children as university students. As a result, students had to cut down their daily expenditures. Due to this crisis, the students had to be affected by various levels of stress leading to disruptions in both physical and mental health. It also caused poor academic performance. Some students had to quit their studies. Stress is an emotional feeling affecting all ages and it appears at any time of the life cycle. The purpose of this study was to identify the level of perceived stress and affecting factors due to the current economic crisis among undergraduates in the Faculty of Health-Care Sciences (FHCS), Eastern University Sri Lanka (EUSL). A cross-sectional descriptive study was conducted using a self-administered online questionnaire to gather information and a complete enumeration was done. The Perceived Stress Scale (PSS) instrument was used to assess the severity of the undergraduate perceived level of stress-related current economic crisis. Demographic variables and affecting factors due to the current economic crisis were considered. The overall mean stress score in the study population was 22.91(SD=5.386). The majority of undergraduates reported moderate stress 70.8% (N=240). A multiple linear regression analysis was applied, Pearson correlation was used, and all necessary tests were performed. There was a statistically significant, positive correlation between the level of perceived stress and their family income per month (p=0.000). The contributing factors correlated with perceived stress were unable to enjoy meeting people, unable to frequently visit home, unable to take meals from outside and instead of cooking, trying to save extra expenditure money, unable to frequent shopping for dresses, cosmetics, jewelry. The level of perceived stress reported by the majority of the students was moderate. Mainly their family income per month contributed to stress among them. Policymakers and the university administration have to consider more about the stress levels of the students and plan suitable programs like scholarships to manage stress.

Impact of Different Drip Emitter Types on Hydraulic Performance and Wetted Zone Characteristics in Okra Cultivation

Drip irrigation system is the most efficient and economical method for irrigation vegetable production. The study aimed to design and evaluate the hydraulic performance of three different types of emitter namely Regular gauge (RG), Compensating pressure (CP) and non-compensating pressure (NCP) using okra as a test of a crop. This study was conducted at the experimental farm of the Faculty of Agricultural Science, Zamzam University in 2023. The treatments were laid out in a randomized complete block design (RCBD) with three replications. Parameters of hydraulic performance of drip emitters were average discharge (Qavg %), discharge variation (Qvar), coefficient uniformity (CU %), coefficient of manufacture variation (CV), emission uniformity (EU %) and statistical uniformity (US %). The results showed that the values of (CU%), (CV), (EU%), (US%) and percentage emitters clogging (Pclog%) were 99.52%, 0.49, 68.01%, 74.14%, 2.8% and 99.32%, 0.36, 52.06%, 63.47%, 1.65% and 99.09%, 0.26, 40.07%, 51.05%, 0.85% for non-compensating pressure (NCP), compensating pressure (CP) and regular gauge (RG respectively. It is considered coefficient uniformity (CU %), was good and found to be within the excellent range while discharge variation (Qvar) was found to be within the desirable range, emission uniformity (EU %), coefficient of manufacture variation (CV), and statistical uniformity (Us %) were found to be within the range of poor, low, acceptable and unacceptable. Thus, the study recommended the best type of emitter was regular gauge (RG), because it has the highest crop yield and water productivity as compared to other emitters, non-compensating pressure emitters (NCP) and compensating pressure emitters (CP)

A Cross-Sectional Study Revealed a Low Prevalence of SARS-CoV-2 Infection among Asymptomatic University Students in Tripoli, North Lebanon.

This study aimed to investigate the SARS-CoV-2 infection prevalence among >18-year-old students in the Faculty of Public Health and Faculty of Sciences at the Lebanese University in Tripoli, Northern Lebanon, in June 2023 and to characterize the circulating Omicron subvariants. Out of 357 participants, only 2 (0.56%) tested positive by qPCR, corresponding to 0.61% (2/326) of asymptomatic students. One case tested positive with a qPCR targeting the Omicron BA.2 variant. These findings indicate a low incidence at that time and emphasize the interest of SARS-CoV-2 surveillance among students.

Factors related to Health Literacy in Illness Prevention among Buriram Rajabhat University Students

A health science student is a health personnel with a role in caring, promoting, preventing, and maintaining health, thus they must be literate and knowledgeable about health in order for people to have a good quality of life. The aims of this study were to assess the level of health literacy in illness prevention and to study the relationship between health literacy and illness prevention among nursing students, Faculty of Nursing, and students from the Department of Public Health, Faculty of Science, Buriram Rajabhat University. The data were analyzed using mean, percentage, standard deviation, and Pearson correlation coefficient. The results revealed that the overall health literacy in illness prevention of nursing students (average score of 82.46 percent, x̄ =4.12, S.D.= 0.7, very good level) was higher than the public health science students (average score of 79.04 percent, x̄ =3.81, S.D.= 0.72, moderate level). When considering each aspect, it was found that health literacy of most nursing students was at a very good level while for the aspect of changing self-health behavior and the aspect of transmission of information in health care were at moderate levels. As for the health literacy of the public health science students, most of them were at a moderate level while the comprehension of adequate information and health services was at a very good level. In addition, health literacy was positively correlated with illness prevention (r=0.248) which indicated that good health literacy had a positive effect on preventing illness.

Empirical Study on Attitude towards Making Decision to Select Mathematics for First-Degree Program

Recently debatable arguments have existed regarding the perceived lack of numerical skills among the graduates from the Humanities and Social Sciences. In response to this concern, the Faculty of Humanities and Social Sciences, Faculties of Art in national universities in Sri Lanka have taken measures to more opportunities to undergraduates to bolster their numerical proficiency. This is achieved through the incorporation of mathematics course units for their degree programs along with the main subject streams. The study focuses on factors that affect the undergraduates’ attitudes towards making the decision to select the subject mathematics for their first-degree program. A sample survey was carried out using structured questionnaire and stratified random sampling technique was utilized to select a sample size of 352 from the undergraduates belongs to Faculty of Humanities and Social Sciences in University of Sri Jayewardenepura. The binary logistic regression model is utilized, and the study revealed that self efficacy, mathematical anxiety, and interest in mathematics are significantly affected students’ attitudes on counting mathematics course units for their degree program. The student who has self-efficacy is 1.03 times more likely to select mathematics course unit at the first academic year than other students. A unit increase of mathematics anxiety with all other factors remaining constant, the odds of a student selecting the mathematics course decreased by 11.2%. When one-unit increases in the interest in mathematics of students the odds of selecting mathematics course unit is 1.06 times more likely to than other peers. These insights suggest that educational institutes, particularly those in the humanities and social sciences, should prioritize enhancing students ‘numerical skills. This can be achieved by providing valuable consideration aimed at refining their curriculum and support mechanism, increasing awareness programmes about the importance of studying mathematics course units within their degree programmes and conducting programmes to reduce mathematics anxiety while fostering an increased interest in mathematics.

Effectiveness of Biochar application on the growth of red chili plants during the vegetative stage under waterlogging

The riparian wetland offers potential for horticultural crop cultivation, such as chili peppers. It is important to consider cultivation techniques and the use of organic matter to improve soil properties, particularly to combat waterlogging during the rainy season. This study aimed to assess the impact of biochar application on the growth of chili peppers (Capsicum annuum L.) during the vegetative stage under waterlogging conditions. This research was conducted at the experimental land of the Agrotechnology Department, Faculty of Plant and Animal Sciences, Universitas Bina Insan from December 2022 to February 2023. This research employed a complete randomized design (RAL) factorial with two factors. The first factor involved waterlogging stress, including control (C) and waterlogging stress (W). The second factor (N) encompassed the application of biochar, namely without biochar (N0), rice husk biochar (N1) and coconut shell biochar (N2) at a dose of 200 g plant-1. The results showed that waterlogging conditions (W) and biochar application (N) showed significantly different results in shoot length, root length, number of leaves, and total dry weight of chili plants, while the interaction (WxN) showed significantly different in shoot length and root length of plants. Treatment without biochar (N0) in waterlogging conditions actually showed shoot length, root length, number of leaves and total dry weight of plants that were significantly higher than treatment coconut shell biochar (N1) and rice husk applications (N2).

The impact of educational and training programs on disaster awareness and preparedness among health sciences students: A quasi-experimental study

Disaster preparedness among health sciences students is critical but often insufficient. This study evaluates the effectiveness of a disaster awareness and impact reduction educational intervention in enhancing disaster preparedness. A quasi-experimental single-group pretest-posttest design was employed, with the intervention consisting of 16 h of education delivered over four weeks via a distance learning platform. The study involved 599 students from the faculties of health sciences, who were assessed at baseline and three months post-intervention. Results indicated that students’ baseline disaster preparedness levels were low, with no significant correlations found between demographic characteristics, previous disaster experiences, or prior disaster preparedness training and baseline preparedness levels. Repeated-measures Analysis of Variance confirmed a significant impact of the intervention after controlling for baseline preparedness levels. Significant improvements were observed post-intervention across all preparedness dimensions: disaster physical protection, disaster planning, disaster assistance, disaster warning systems, and total preparedness levels (p < .001). The most substantial gains were noted among students with initially low preparedness levels. These findings emphasize the importance of integrating disaster preparedness education into health sciences curricula to better equip future healthcare professionals for effective disaster response.

Comparative Analysis of the Distribution of Natural Lighting with Artificial Lighting in Auditorium at Indonesia University of Education, at Faculty of Mathematics and Natural Sciences Building

Abstract This article provides an indepth analysis of the lighting conditions in the auditorium at the Indonesia University of Education, specifically within the Faculty of Mathematics and Natural Sciences. The study aims to assess the effectiveness of both natural light from windows and artificial light from lamps in accommodating large gatherings of up to 300 people. Using AutoCAD and DIALux, we conduct a simulation experiment to visualize the lighting system, considering factors such as the distribution of natural light and the impact of artificial lighting. Our methodology involves specific parameters for data analysis to ensure a comprehensive evaluation. While observing the auditorium, we note potential challenges, such as the limited impact of natural light. This finding raises questions about the need for adjustments to the architectural design or the inclusion of additional natural light sources. Conversely, the artificial lighting appears to be abundant and sufficient for illuminating the entire space. Considering the broader implications, the study addresses the significance of optimizing lighting conditions in auditoriums for improved user experience and potential energy efficiency. The findings contribute to the ongoing discourse on effective lighting design in educational spaces. This research is not without limitations, and future work could explore more nuanced aspects of lighting design or investigate the feasibility of implementing sustainable lighting solutions. In conclusion, this study offers valuable insights into auditorium lighting, guiding future research and practical interventions for enhanced lighting conditions in similar settings.

Evaluation of Auditorium Acoustics in the Faculty of Mathematics and Science Education, Universitas Pendidikan Indonesia, Bandung.

Abstract As a space whose function is prioritized for speeches, the auditorium must respond well to acoustics so that listeners get audibly comfortable when listening to speakers speak. In this study, the Japan International Cooperation Agency (JICA) Auditorium located in the Faculty of Mathematics and Natural Sciences will be simulated to determine the acoustic quality of the auditorium. The method used is simulation using Ecotect software. The simulation is done by creating a 3D model and inputting several parameters, such as the absorption coefficient of the material used in the auditorium and the placement of speakers in it. This simulation determines the reverberation time, the initial decay time, or how long the room muffles the sound after the sound source stops, and the sound distribution produced by the sound source or speaker in the room. Based on the simulation results, the acoustic quality of the JICA auditorium is good. This is due to several factors, such as the selection of materials with a high absorption coefficient on the back wall and the shape of the room design, which uses geometric shapes with zigzag patterns on the ceiling and walls, as well as the slope used on the floor and ceiling.

The effect of digital storytelling on nursing students' compliance with isolation precautions and their knowledge levels: A randomized controlled trial

AbstractBackgroundDigital storytelling is a teaching tool that can help nursing students master the curriculum and improve their skills. This study investigated the effect of digital storytelling on nursing students' knowledge levels and compliance with isolation precautions.MethodologyA pretest‐posttest open‐label randomized controlled trial. This study was conducted in the nursing department of the faculty of health sciences of a university in Türkiye. The sample consisted of 109 fourth‐year nursing students divided into experimental (n = 66) and control (n = 43) groups. Data were collected using a Demographic Characteristics Questionnaire (DCQ), the Isolation Knowledge Test (IKT), the Questionnaire of Students' Opinions on Digital Storytelling (QSODS) and the Scale of Compliance with Isolation Precautions (SCIP). The experimental group participated a digital storytelling activity, whilst the control group received an education based on the curriculum. The data were analysed using the Mann–Whitney U test, the Wilcoxon test, analysis of variance (ANOVA), and the Spearman correlation test.Results and ConclusionsThe experimental group had significantly higher posttest IKT and SCIP scores than the control group (p &lt; 0.05). Both groups had lower IKT and SCIP scores 2 months after the experiment. However, the change was much smaller in the experimental group. Digital storytelling helped the experimental group participants learn about isolation precautions and how to comply with them. Digital storytelling also promotes learning retention. In conclusion, digital tools are effective in distance learning.

Discipline as Context: Arts and Science Students' Views on Key Concepts in the ACRLFramework

ABSTRACTThe introduction of the Association of College and Research Libraries' (ACRL, 2016) Framework for Information Literacy for Higher Education, or “the Framework,” has fostered efforts to apply the document's concepts to information literacy instruction (ILI) to meet the needs of post‐secondary students across faculties. However, little research has directly compared students' perspectives on the Framework's concepts by discipline. This poster presents findings from a larger, mixed‐methods project investigating student perspectives on the Framework in which participants in the faculties of arts (n = 123) and science (n = 90) expressed distinct views and rankings. Their perspectives particularly diverged around perceived roles in assessing the authority of information sources and how “relevant to their experience in school” they found most Framework frames. This project expands upon emerging learner‐centered research aiming to meaningfully improve Framework‐based ILI through its direct disciplinary comparisons and use of the recently developed Information Literacy Reflection Tool (ILRT; Robertson et al., 2022).

AI-based automated construction of high-precision Geobacillus thermoglucosidasius enzyme constraint model

Geobacillus thermoglucosidasius NCIMB 11955 possesses advantages, such as high-temperature tolerance, rapid growth rate, and low contamination risk. Additionally, it features efficient gene editing tools, making it one of the most promising next-generation cell factories. However, as a non-model microorganism, a lack of metabolic information significantly hampers the construction of high-precision metabolic flux models. Here, we propose a BioIntelliModel (BIM) strategy based on artificial intelligence technology for the automated construction of enzyme-constrained models. 1) . BIM utilises the Contrastive Learning Enabled Enzyme Annotation (CLEAN) prediction tool to analyse the entire genome sequence of G. thermoglucosidasius NCIMB 11955, uncovering potential functional proteins in non-model strains. 2). The MetaPatchM module of BIM automates the repair of the metabolic network model. 3). The Tianjin University of Science and Technology-kcat (TUST-kcat) module predicts the kcat values of enzymes within the model. 4). The Enzyme-insert procedure constructs an enzyme-constrained model and performs a global scan to address overconstraint issues. Enzymatic data were automatically integrated into the metabolic flux model, creating an enzyme-constrained model, ec_G-ther11955. To validate model accuracy, we used both the p-thermo and ec_G-ther11955 models to predict riboflavin production strategies. The ec_G-ther11955 model demonstrated significantly higher accuracy. To further verify its efficacy, we employed ec_G-ther11955 to guide the rational design of L-valine-producing strains. Using the Optimisation Procedure for Identifying All Genetic Manipulations Leading to Targeted Overproductions (OptForce), Predictive Knockout Targeting (PKT), and Flux Scanning based on Enforced Objective Flux (FSEOF) algorithms, we identified 24 knockout and overexpression targets, achieving an accuracy rate of 87.5%. Ultimately, this led to an increase of 664.04% in L-valine titre. This study provides a novel strategy for rapidly constructing non-model strain models and demonstrates the tremendous potential of artificial intelligence in metabolic engineering.

Ergonomics, Students’ Well-being, and Technology-Enhanced Learning at Usmanu Danfodiyo University, Sokoto, Nigeria

Ergonomics is the study of designing equipment and devices that fit the human body, its movements, and its cognitive abilities. In the context of students in the 21st century, ergonomics is important because of the increasing amount of time that students spend using technology, such as computers, tablets, and smartphones. Poor ergonomics can lead to physical discomfort, pain, and even long-term injuries, such as carpal tunnel syndrome and back problems. This article assessed the relationship between students, some ergonomic factors they may come into contact with during their stay at the university, and how the relationship can be improved. The study adopted a correlational survey research design. All the undergraduate students from the faculty of sciences formed the population of the study. 357 students were randomly selected to participate in the study. The determination of the sample size was guided by Research Advisors (2006). An instrument titled “Ergonomics and Students’ Health” was developed and used for data collection. It was validated, and it was used to conduct a pilot study. A reliability index of 0.98 was obtained using Chrombach Alpha at the 0.05 level of significance. Descriptive and inferential statistics were used for data analysis. Results from the study found that most of the students do not see ergonomics as a factor of concern. A negative relationship was also found between ergonomics and students’ health conditions at the university. It was concluded that ergonomics is a silent issue with numerous negative health effects that needs urgent responses from both students and university management. It was therefore recommended that the university management take the necessary measures to improve the ergonomic conditions of its students.
