Quality education is highly dependent on the level of professionalism of teachers and the effectiveness of educational leadership. Most studies related to educational leadership focus on the Principals and Headmasters, rather than examining the overall leadership including middle leaders who are the backbone of educational leadership. A more comprehensive study among education leaders is needed to further improve the quality of education in Malaysia. This study aimed to obtain expert consensus on the construct of professional leadership competencies for middle leaders in matriculation colleges using the Fuzzy Delphi Method. An instrument containing a list of elements of professional leadership competencies was presented to a total of 30 experts from various fields and background. The findings of this study indicate that the expert panel agreed on the constructs and elements of professional leadership competencies proposed. The threshold values of all 13 elements tested met the conditio.....

The chemical composition, antifungal, antibiofilm, and molecular docking studies of the essential oil obtained from Lindera caesia were investigated. A total of thirty-nine components (96.7%) were identified using gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The major components included terpinen-4-ol (26.3%), neo-intermedeol (23.2%), eudesma-4,11-dien-3-one (10.4%), and o-cymene (5.3%). The antifungal activity was tested against Candida albicans and Streptococcus mutans using the broth microdilution assay, whereas the microbial biofilms were determined using a semi-quantitative static biofilm. The essential oil exhibited activity against C. albicans (MIC 125 g/mL) and S. mutans (MIC 250 g/mL), and increased the biofilm of C. albicans by 31.25% when treated with 500 g/mL. The molecular docking study shows neo-intermedeol, eudesma-4,11-dien-3-one, ?-selinene, and ?-selinene as the good candidate to target Erg11 with a binding energy of ?7.3 kcal/mol. The.....

Political cyber-troopers is a term that refers to activists paid to spread political propaganda in the media. The emergence of the cyber-troopers movement was seen to be significant in the 12th General Election and became more active in the 14th Election.

GeoGebra software has been identified as a potential aid in the teaching and learning process. This study aims to examine the impact of GeoGebra software on achievement and enjoyment in the context of the polygon topic. A non-equivalent group pretest-posttest design was utilized, and 60 students were randomly assigned to either the experimental or control group. The data collected was analyzed using descriptive and inferential statistical methods with the assistance of SPSS version 26. The findings revealed that the level of achievement and engagement among Form Two students in the study population was already high regarding the Polygon topic. How-ever, the results demonstrated that students who received instruction utilizing GeoGebra soft-ware achieved even higher levels of achievement and engagement than those who experienced traditional teaching methods. As a result, integrating GeoGebra software into the classroom proved to be an effective tool for enhancing student achievement and.....

Using a cross-sectional study design, twenty archery players participated in the study (age range from 1321 years old). The participants were divided into two groups: intermediate groups and elite groups. The revised Competitive State Anxiety-2 (CSAI-2R) was used to measure competitive anxiety and arousal. In addition, heart rate was measured using a Polar heart rate monitor, and a digital pulse oximeter (Instant Read Finger Pulse Oximeter, Model OX250, MeasuPro, USA) was used to monitor participants blood oxygen percentage. Results. The results of the groups were compared using descriptive, independent T-test and Pearson correlation tests. The descriptive analysis indicated a pattern of decrement in cognitive anxiety, som.....

Background: Studies assessing post-activation potentiation (PAP) responses comparing male and female athletes are conflicting. Objectives: This study investigated whether differences exist in the duration for optimal post-preload stimulus measures on performance in male and female team sport athletes. Methods: Twenty-four participants (12 males and 12 females) participated in the study. Two familiarization sessions were conducted with each participant. Then, three experimental conditions were implemented, incorporating a standardized warm-up, followed by back squats (conditioning exercises) and varying passive recovery times of 4 min (PAP4), 8 min (PAP8), or 12 min (PAP12). Following the recovery, players performed three physical performance measures related to team sports: A countermovement jump, a modified agility t-test, and a 20-m linear sprint. The significance level was set at P < 0.05. Results: All performance measures were significantly greater in PAP12 than in PAP4 and PAP8 co.....

The chemical composition of the essential oil of Rothmannia schoemannii Tirveng. (Rubiaceae) was investigated for the first time. The essential oil was obtained by hydrodistillation and fully characterised by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). In total, 28 components were identified in the essential oil, which made up 99.6% of the total oil.
