Assessment for Learning (AfL) and Assessment as Learning (AaL) are gaining increasing prominence especially in university EFL writing lessons. This study sheds light on the practices and values of Indonesian EFL writing teachers towards AfL and AaL strategies during the constrained context of online learning setting because of the COVID-19 pandemic. By using descriptive statistics and thematic analysis, explanatory sequential mixed method was used in conjunction with a case study research design. Quantitative data were obtained from 54 teachers who responded to the AfL and AaL Strategy Questionnaire (AfL-AaLSQ), indicating their practices and values of AfL-AaL strategies. Meanwhile, the qualitative data were the results of interview sessions with seven selected participants, who described their practices and values in details. The findings show that all respondents accorded high importance to all AfL-AaL strategies and rated themselves as frequently implementing the AfL-AaL strategies......

Background and Study Aim Material and Methods In the physically demanding combat sport of Silat, strength and power dominate. Consequently, applying various stance widths during barbell hip thrusts may tailor athletes lower-body exercises to individual needs. This has the potential to optimize performance. The aim of this study is to investigate the impact on performance of power, speed, and stance width among Silat combat athletes. Participants performed 10RM tests in three stance widths: wider than shoulder width (WSW), normal shoulder width (NSW), and narrower than shoulder width (NRW). This was done using a 72-hour counterbalance cross-over study design. Power and velocity were measured and analyzed using a mixed ANOVA design. Results The results indicated a significant main effect of stance width on power (F(2,56) = 3.086, p < 0.05) and velocity (F(2,56) = 3.683, p < 0.03) output. Both males and females demonstrated the highest power in NRW (M = 413.26, SD = 131.76; M = 239.53, SD.....

The present study focuses on using jackfruit seed waste (JSW) for bioremediation of heavy toxic metals from water. The fruit is abundantly grown in India and Far East countries and produces myriad tons of seeds. A simple procedure is developed in the laboratory by thermally activating JSW by orthophosphoric acid at 500 C. Surface morphology, porosity, and structural analyses of the resultant biochar were conducted. The activated biochar was applied for batch adsorption of several heavy metal ions: Fe(III), Cd(II), Cu(II), Pb(II), and Mn(VII) at pH 7. The average heavy metal uptake by activated JSW biochar is 76.4 mg g?1, 79.4 mg g?1, 97.9 mg g?1, 79.9 mg g?1, and 79.8 mg g?1 for Fe(III), Pb(II), Cu(II), Cd(II), and Mn(VII), respectively. The experimental conditions were optimized to remove heavy metals at neutral pH. The adsorption process was exothermic, and Langmuir and pseudo-second-order kinetic study models were best fitted. The observation was in close agreement with the experime.....

Since the COVID-19 pandemic, telemedicine or non-face-to-face medicine has increased significantly. In practice, various types of medical images are essential to achieve effective telemedicine. Medical image encryption algorithms play an irreplaceable role in the fast and secure transmission and storage of these medical images. However, most of the existing medical image encryption algorithms are full encryption algorithms, which are inefficient and time-consuming, so they are not suitable for emergency medical scenarios. To improve the efficiency of encryption, a small number of works have focused on partial or selective encryption algorithms for medical images, in which different levels of encryption strategies were adopted for different information content regions of medical images. However, these encryption algorithms have inadequate security more or less. In this paper, based on the Logistic map, we designed an improved variable dimension map. Then, an encryption algorithm for med.....

As global median temperatures continue to rise, the demand for active cooling systems (ACs) is increasing. These systems are particularly prevalent in developed countries for maintaining comfort during hot weather. Various ACs technologies are available, and assessing their performance in multi-perspective settings is necessary to determine the best option for intended usage. This requires an evaluation platform for assessment. This paper presents a novel multi-criteria decision-making (MCDM) model based on a new integrated 2-tuple linguistic Pythagorean fuzzy-weighted zero-inconsistency (2 TLP-FWZIC) and modified 2-tuple linguistic Pythagorean fuzzy multi-attributive border approximation area comparison (2TLPF-MABAC). The former is used to determine the importance of assessment criteria, while the latter is employed for selecting the optimal ACs using the obtained weights. The first-level weighting results reveal that performance criteria were predominantly favored for assessment, wit.....

In soccer, goal scoring becomes the main factor in distinguishing between the winning and losing teams. One of the most crucial components of a soccer team's offensive performance is the goal-scoring path since it has been correlated with a higher likelihood of winning games. Therefore, the study aims to investigate the pathway of goal scoring among the winning teams in the previous seven consecutive seasons (2015/2016 2021/2022) in the UEFA Champions League competition. A total of 216 goals from the UEFA Champions League competitions in seven prior seasons (2015/2016-2019/2020) were examined. The pathway of goal scoring has been divided into long sequence passing, short sequence passing, and others. All the data have been recorded by using hand notational analysis and analyzed by using one-way ANOVA. A total of 216 goals were scored throughout the competition showing that 108 goals were from long sequence passing, 57 goals were from short sequence passing, and 51 goals came from other.....

This study aims to investigate the relationship between perceived coachs competence support, task orientation, self-efficacy and engagement of Chinese high school football players from a competency motivation perspective. A cross-sectional survey of 385 Chinese high school football players (228 boys; 157 girls; Mage = 16.07 years; SD = 1.15; range = 14-19 years) was conducted using proportional stratified random sampling. A multivariate mediation model was tested using structural equation modelling (SEM) to investigate the relationships of perceived coaching competency support on athlete engagement directly, or indirectly through task orientation and self-efficacy. Perceived coachs competence support positively predicted athlete engagement through task orientation and self-efficacy (? = .116, p < 0.01; ? = .112, p < 0.01), and perceived coachs competence support positively predicted self-efficacy through task orientation, and then positively predicted athlete engagement (? = .045, p < .....

Push-up is an effective bodyweight exercise that can help improve the muscular endurance and strength of the upper limb muscles from health risks. Additionally, there are many ways to perform push-up, and it might cause several changes to its effectiveness. This includes changing the leg conditions such as legs open wide, legs open to shoulder-width, and narrow legs. The study aimed to investigate the effect of leg width during push-ups on muscle activity and performance. A total of 30 trained men (22.36 2.17 years old) participated in the study. Participants were required to perform push-ups in three conditions; i) leg open wide, ii) leg open to shoulder width, and iii) narrow leg. The electromyography (EMG) was used to evaluate the activity of the anterior deltoid (AD), pectoralis major (PM), and triceps brachii (TB) muscles in all conditions. Performance on push-ups was also assessed by the number of repetitions for each condition in this study. The results of one-way repeated measu.....
