How to Estimate Absolute-Error Components in Structural Equation Models of Generalizability Theory

Structural equation modeling (SEM) has been proposed to estimate generalizability theory (GT) variance components, primarily focusing on estimating relative error to calculate generalizability coefficients. Proposals for estimating absolute-error components have given the impression that a separate SEM must be fitted to a transposed data matrix. This paper uses real and simulated data to demonstrate how a single SEM can be specified to estimate absolute error (and thus dependability) by placing appropriate constraints on the mean structure, as well as thresholds (when used for ordinal measures). Using the R packages lavaan and gtheory, different estimators are compared for normal and discrete measurements. Limitations of SEM for GT are demonstrated using multirater data from a planned missing-data design, and an important remaining area for future development is discussed.
Influence of Dietary Supplementation of Kigelia pinnata and Plukenetia conophora Leaves on Cytokine Expression, Immunoglobulins, Blood Chemistry, Caecal Microbiota and Meat Quality in Broiler Chickens

This study examined the effect of dietary supplementation of Kigelia pinnata (KPL) and Plukenetia conophora (PCL) leaves in comparison with oxytetracycline (OXY) and butylated hydroxyanisole (BHA) on growth performance, selected blood biochemical parameters, caecal microbiota, splenic interleukins (IL), serum immunoglobulins (Ig), carcass traits, meat quality, and oxidative stability in broiler chickens. One day old Arbor Acres chicks (n=420) were randomly assigned to either basal diet only (BD); basal diet + 0.5 g/kg oxytetracycline + 0.12 g/kg BHA (OXYBHA); basal diet + 1 g/kg KPL (KPL-1); basal diet + 2 g/kg KPL (KPL-2); basal diet + 1 g/kg PCL (PCL-1); or basal diet + 2 g/kg PCL (PCL-2) for 42 d. Each dietary treatment had seven replicates with 10 chicks per replicate. Supplemented birds gained (P < 0.05) more weight and had a better feed conversion ratio compared with the BD birds. Hematological indices, IL-1β, and IL-6 did not differ among the treatments. BD birds had lower (P < 0.05) carcass weight and IL-10, and higher (P < 0.05) IgG, IgM, Salmonella spp. , and E. coli counts than the supplemented birds. The KPL-2 birds had the least (P < 0.05) E. coli and Salmonella spp. counts and IgM among the supplemented birds. Lactobacillus spp. count was lower (P < 0.05) in OXYBHA birds compared with KPL and PCL birds. Carbonyl and malondialdehyde contents in the Sartorius muscle, and drip loss and carbonyl content in the Pectoralis muscle of the BD birds were higher (P < 0.05) than those of the supplemented birds. These results illustrate that the 2 g/kg KPL and 2 g/kg PCL could be used as an antioxidant and an antimicrobial in the diets of broiler chickens.
Enducation Environment And The Impact Of Pandemic Covid-19 In Student Perspective

There are several objectives of this research, namely the COVID-19 disaster to provide natural environmental learning or education to humans, including educating people in climate-friendly and low-emission behaviour, saving energy, saving water, and recognizing the ability of the universe. Another goal is to find the social, religious and psychological impact of COVID-19 that students at Ibn Khaldun University Bogor. The research method approach used a descriptive qualitative approach. Data were collected by in-depth interviews with the class leader of semester VI students. The sample was selected through a purposive technique. The results were scrutinized carefully through triangulation and source triangulation techniques. The results show that students have the view that the arrival of COVID-19 has taught humans to behave friendly to the climate because with the presence of COVID-19, students are no longer at campus, lecturers and campus officers. This method is classified as an action to reduce glass emissions as a cause of global warming. In addition, energy and water are used very little and even at the beginning of the lockdown, these natural resources were not used, thereby educating people to save energy and water through the campus. The use of energy also causes climate problems so that it can economically reduce emissions. After that, humans are taught to live cleanly because to cope with this disaster, humans must maintain the cleanliness of the environment, themselves and places of worship. Then, the COVID-19 outbreak has a social impact because students no longer have face-to-face contact with other students, disrupt religious activities such as religion and also make students psychologically stressed
The Effect of Accrual Quality and Operating Cash Flows on Future Cash Flows in the Basic Industry and Chemical Sectors

Accrual quality in this study is measured by the accruals-working capital approach, referring to Dechow and Dichev [1] and Francis et al. [2], cash flow is measured by the ratio of operating cash flows to assets. The population of this research is the Basic Industry and Chemical sector companies listed on the Indonesia Stock Exchange for the period 2014-2018. The samples were determined using purposive sampling which resulted in 144 firms year came from 32 companies. The results of this study showed that there is a significant positive effect the accrual quality and operating cash flow on future cash flows. Management should manage the company's operating cash flow efficiently, and simultaneously improve the quality of the company's accruals which will be a positive signal for investors creditors
Evolution of Cardiac Tissue and Flow Mechanics in Developing Japanese Medaka

The effects of pressure drop across cardiac valve cushion regions and endocardial wall strain triggering cardiac morphogenesis in a teleost species heart are poorly understood. In the presented work, we utilize microscale particle image velocimetry (µPIV) flow measurements of developing medaka hearts from 3 to 14 dpf (n = 4–5 at each dpf) to quantify the pressure field and endocardial wall strain. Peak pressure drop at the atrioventricular canal (ΔPAVC) and outflow tract (ΔPOFT) show a steady increase with fish age progression. Pressure drops when non-dimensionalized with blood viscosity and heart rate at each dpf are comparable with measurements in zebrafish hearts. Retrograde flows captured at these regions display a negative pressure drop. A novel metric, Endocardial Work (EW), is introduced by analyzing the ΔPAVC-strain curves, which is a non-invasive measure of work required for ventricle filling. EW is a metric that can differentiate between the linear heart stage (< 100 Pa-%), cardiac looped chamber stage (< 300 Pa-%), and the fully formed chamber stage (> 300 Pa-%).
ASSOCIATION BETWEEN EXCLUSIVE BREASTFEEDING PRACTICE, TABURIA SUPPLEMENTATION, AND STUNTING PREVALENCE AMONG CHILDREN AGED 24–60 MONTHS IN SIDOTOPO WETAN, SURABAYA

Stunting is a condition in which a child’s height is shorter than other children of the same age. Exclusive breastfeeding is a factor that can aff ect the stunting prevalence in Indonesia. In addition, specifi c nutritional intervention through multi-micronutrient supplementation called Taburia is given to prevent stunting. This study was aimed to determine the relationship between exclusive breastfeeding practice and taburia supplementation in children aged 24-60 months in the working area of Sidotopo Wetan Health Center, Surabaya City. This study used secondary data obtained from a child monitoring survey database from the Surabaya City Health Offi ce in the working area of Sidotopo Wetan Health Center. The samples size was 141 children aged 24–60 month, and the statistical analysis employed was the chi-square test. The results showed that the stunting proportion was 54.60%. There was a relationship between exclusive breastfeeding practice and the stunting incidence (p = 0.047). Children who did not provide exclusive breastfeeding had a higher risk 1.97 times of stunting. Taburia supplementation also had a signifi cant relationship with stunting incidence (p = 0.016). Children with non taburia had a higher risk 2.35 times of stunting. Based on these results, it can be concluded that the prevention of stunting can be overcome by maximizing exclusive breastfeeding practice and complementary foods, also the allocation of taburia
Romanian Students’ Appraisal of the Emergency Remote Assessment due to the COVID-19 Pandemic

The response of most educational institutions to the health crisis triggered by the COVID-19 pandemic was the adoption of emergency remote teaching and assessment. The paper aims to evaluate students’ satisfaction with assessment activities in a Romanian university and to identify elements pertaining to sustainable assessment in the post-pandemic period. A collaborative research strategy was developed with students being invited as co-researchers for data collection by distributing an online questionnaire and for interpretation of the results in a focus group. The factor analysis of the responses to the survey extracted two pillars pertaining to students’ appraisal of remote assessment activities: Knowledge, and leisure and stress. The discussion in the focus group showed that the research helped participants to process and reason their experience with remote assessment activities in the summer of 2020. Students missed their academic rituals and interactions with peers and teachers. Despite their enthusiasm for technological innovation and the benefits brought by computer assisted assessment, students are inclined towards preserving human evaluators, preferably from their familiar teachers, in educational settings resembling pre-pandemic academic life. A sustainable, resilient model of education needs to be based on retaining features identified as acceptable by students as examinees.
A comparative study of mechanical and machining performance of polymer hybrid and carbon fiber epoxy composite materials

Fiber-reinforced plastics are known as advanced composite materials thanks to their high strength and lightweight features. Carbon fiber reinforced polymers (CFRPs) are one of the high-performance and high-cost fiber-reinforced polymer (FRPs) materials. They are used in several high-performance engineering applications such as motorsports, marine, aviation, energy and defense industry. The cost of carbon fiber is higher compared to many other materials, more competitive and cost-effective productions will spur the demand for composite parts exponentially. Thus, hybrid laminate composite containing carbon and glass fiber materials were manufactured as an alternative for CFRP materials. Because using glass fiber prepreg instead of carbon fiber prepreg will lead the material to become cheaper. However, machining of the FRP materials is still an important issue. For this reason, the present study is focused on the mechanical and machining performance of the polymer hybrid and carbon fiber epoxy composites.
Factors Affecting Occupants’ Satisfaction in Governmental Buildings: The Case of the Kingdom of Bahrain

Satisfaction is a very important factor in improving productivity and performance in the work environment. This study aims to investigate the levels of occupants’ satisfaction with the indoor environmental quality (IEQ) in the governmental buildings in the Kingdom of Bahrain and to investigate the impact of occupants’ demographics and building attributes (non-IEQ factors) on these levels. For these purposes, the study used a questionnaire that has 17 indoor environmental quality (IEQ) factors in addition to a group of non-IEQ factors. The questionnaire was distributed by hand or using email to 279 employees in the Bahraini governmental sector. The findings of the study revealed that occupants in the Bahraini governmental buildings are not strongly satisfied with IEQ factors, especially with sound privacy, followed by visual privacy and amount of space, and then noise levels. The findings also showed that for most IEQ factors, men are more satisfied than women are, those who work in enclosed private offices are more satisfied than those who work in open-plan offices, and those who have central air-conditioning at their workplace are more than those who have a wall-mounted air conditioner. The impact of age, nature of work, duration of working in the current building and at the current workstation, weekly working hours, and proximity to the window were also investigated. Accordingly, a group of recommendations was suggested aiming to improve the levels of occupants’ satisfaction.
Effect of Muscle-Specific Fatigue on the Risk of Anterior Cruciate Ligament Injury in Females

The aim of our study was to investigate the effect of muscle-specific fatigue of the quadriceps and hamstring muscles on the biomechanical factors of anterior cruciate ligament (ACL) injury using musculoskeletal modeling techniques during directional diversion maneuver. Fifteen female subjects performed a directional diversion maneuver under three treatment conditions (quadriceps fatigue, hamstring fatigue, and control gait). Data from the 3D motion capture system and force platform were used to extract anterior/posterior ACL forces using the two-bundle ACL musculoskeletal modeling approach. A decrease in maximum extension (51.3%) and flexion (50.7%) torque after fatigue was observed. After quadriceps fatigue, the extension (p = 0.041) and adduction moments (p = 0.046) of the knee joint and the mean anterior bundle of ACL force (p = 0.021) decreased significantly. The knee flexion angle (p = 0.003), knee valgus angle (p = 0.013), and shear force (p = 0.043) decreased significantly after hamstring fatigue. The decrease in ACL force after quadriceps fatigue confirms its significant role in causing an ACL injury. However, no significant differences in ACL load after hamstring fatigue leads us to speculate that the antagonist muscle group, i.e., the hamstring, might not have a preventive mechanism against ACL injury.
Comparison of Suture-Button Versus Hook-Plate Fixation for Acromioclavicular Joint Injuries

Background: This retrospective study aimed to compare the clinical and radiological results of clavicular hook plate fixation versus suture-button fixation of acromioclavicular joint (ACJ) dislocations. Methods: 21 patients are retrospectively evaluated in the present study whom diagnosed as type III-V ACJ dislocations and treated by two different surgical methods. The hook plate group comprised 9 patients to whom acromioclavicular fixation. The suture-button group comprised 12 patients to whom coracoclavicular fixation. All patients were evaluated by Constant Murley Score (CMS) and visual analogue score (VAS). Loss of reduction and radiological results were evaluated with the coracoclavicular distance (CCD). Results: The average follow-up was 31 months (range, 15–56 months). There was no significant difference between hook-plate and suture-button groups in terms of CMS. However, VAS in hook plate group better than suture-button group (p = 0.038). Suturebutton fixation adjusted the CCD more than hook plate fixation compared to the opposite shoulder (p = 0.482). Conclusions: There was no statistically significant difference between the hook plate and suture-button group in terms of the clinical outcomes. However, CCD in the suture-button group was better adjusted to the hook plate group. Suture-button fixation is a good option for the treatment of ACJ dislocations, as implant removal may be required in most cases in which the hook plate is applied.
Is there a relationship between the overhead press and split jerk maximum performance? Influence of sex

The aims of this study were to (I) determine the differences and relationship between the overhead press and split jerk performance in athletes involved in weightlifting training, and (II) explore the magnitude of these differences in one-repetition maximum (1RM) performances between sexes. Sixty-one men (age: 30.4 ± 6.7 years; height: 1.8 ± 0.5 m; body mass 82.5 ± 8.5 kg; weightlifting training experience: 3.7 ± 3.5 yrs) and 21 women (age: 29.5 ± 5.2 yrs; height: 1.7 ± 0.5 m; body mass: 62.6 ± 5.7 kg; weightlifting training experience: 3.0 ± 1.5 yrs) participated. The 1RM performance of the overhead press and split jerk were assessed for all participants, with the overhead press assessed on two occasions to determine between-session reliability. The intraclass correlation coefficients (ICC) and 95% confidence intervals showed a high reliability for the overhead press ICC = 0.98 (0.97 – 0.99). A very strong correlation and significant differences were found between the overhead press and split jerk 1RM performances for all participants (r = 0.90 [0.93 – 0.85], 60.2 ± 18.3 kg, 95.7 ± 29.3 kg, p ≤ 0.001). Men demonstrated stronger correlations between the overhead press and split jerk 1RM performances (r = 0.83 [0.73-0.90], p ≤ 0.001) compared with women (r = 0.56 [0.17-0.80], p = 0.008). These results provide evidence that 1RM performance of the overhead press and split jerk performance are highly related, highlighting the importance of upper-limb strength in the split jerk maximum performance.
The Conceptual Synthesis and Development of a Multifunctional Lawnmower

This study aims to develop a novel, original and multifunctional lawnmower through reviews of patent literature, research literature and variants of existing lawnmowers. After a detailed conceptualisation process, Autodesk Inventor (version 2019) is used for the finalised design drawing and stress simulation. The prototype is fabricated and tested through several experiments for usability validation which included tests on sound intensity level, cutting ability, polishing performance and battery power durability. Using Minitab 19, the data for the sound intensity and cutting ability experiments are analysed with two-sample t-tests. The data for the polishing performance and battery power durability experiments are analysed through observations, mean comparisons, and manual calculations. Significant differences are found to exist between the tested and control parameters in the context of each experiment, with the outcomes supporting the usability and performance of the present study’s multifunctional lawnmower. This study showed that the prototype has the potential to solve not only some of the problems in conventional lawnmowers but also a few limitations in existing robotic lawnmowers. The outcome of this study intends to benefit society by advancing innovation in lawn maintenance and improving quality of life.
Effects of a Short Interpregnancy interval on Pregnancy Outcomes

Background: Birth spacing is an important subject that is put into consideration by obstetricians to be discussed with women who are thinking about getting pregnant. A decision that is taken by a couple to plan or postpone a pregnancy is affected by many factors. These factors can include the age of the couples, availability of family planning counseling, last pregnancies outcome, cultural aspects, religious beliefs, personal preference, fecundity and fertility aspirations. Aim of the work: To investigate the effects of a short interpregnancy interval on the subsequent pregnancy. Patients and methods: This study is designed as retrospective cohort study at obstetrics and gynecology department at EL-Sayed Galal university hospital and El-Monira general hospital between January 2020 till December 2020. Results: The results of this study showed that there were no any differences of great significance between the studied groups regarding the maternal complications. The results of this study showed that preterm labor, babies of SGA, LBW and Jaundice were linked to the Short IPI group. Conclusion: One of the most important subjects in obstetric practice is birth spacing. In this study we have investigated the effects of a short inter-pregnancy interval on the pregnancy outcomes and what possible determinants there are for a short IPI. After analyzing the results of this study, the following conclusions were made: A short IPI was associated with Small-for-Gestational age babies. This finding can impact neonatal morbidity. So, one of the ways to prevent SGA and other unfavorable neonatal outcomes is to advise women of reproductive age about the importance of adequately spacing their children. In our study; Breastfeeding and the use of contraceptive methods were factors associated with a longer IPI.
Does gamification work in a serious context? The influence of gamification, utilitarian, and hedonic features in the community-based crowdfunding platform

Crowdfunding can provide financial aid to the underserved in a fast and safe manner. With the diffusion of technology, more people have relied on online crowdfunding platforms to fund their projects. However, researchers have found that contributors’ willingness to support the projects on crowdfunding platforms financially has been on the decline. This study aimed to investigate the ability of crowdfunding platform features to influence the intentions of potential contributors to donate on the platform. This research proposed three variables―utilitarian features, hedonic features, and gamification features―based on economic utility theory, flow theory, and persuasive theory. Due to the nascent stage of the crowdfunding environment in Malaysia, this study managed to collect 176 valid responses through virtual snowball sampling method. SPSS 25.0 was employed to test the three hypotheses. The empirical findings reveal that utilitarian features were the most crucial factor in driving contributors’ intention to participate in a crowdfunding project. Hedonic and gamification features, on the other hand, do not directly influence contributors’ behavior. Theoretically, this study enriches the literature on human-computer interaction by examining the role of the crowdfunding platform to attract potential contributors. Also, enhances the understanding of the implementation of gamification in the crowdfunding platform. Finally, this research suggests that future studies should conduct research that specifically involves advanced game-like settings to investigate the real potential of gamification in crowdfunding activities. Keywords : Crowdfunding, flow theory, gamification, hedonic, persuasive theory, utilitarian.
Combined Effects of Microwave and Ionizing Radiation on Mouse

Objective To explore the radioproctective effect of microwave on injury induced by γ-ray.Methods Male and female Kunming mice were divided into 3 groups,including the 1st group(microwave+ radiation),the 2nd group(radiation+microwave),the 3rd group(radiation). The animals in 1st group exposed to microwave(f:900 MHz,flux density:150 μW/cm2) for 12 d(1 hour a day),then animals in the total 3 groups were irradiated once with 10 Gyγ-rays,after that in the 2nd group were exposed to microwave(f:900 MHz,flux density:150 μW/cm2),1 h/d,until the death of animals.The difference in WBC;body weight;survival rates were observed in different groups.Results It was found that in the 3rd group,WBCs decreased after radiation.Compared with group 3,WBC and the 5-day survival rate in the 1st group were higher,but weight was rather unchanged.Blood cells in the 2nd group were higher than those in the only radiation group,but there is no significant difference between group 2 and group 3 for body weight and 5-day survival rate.Conclusion Microwave before and after ionising radiation might have protective effect on radiation-induced animal injury.
