COVID-19 Pandemic: A Consequential Global Hazard to Public Mental Health

Background: The outbreak of COVID-19 infection in humans first reported in Wuhan (China) which has spread around the world and having a significant impact on global health and mental health. It has caused widespread psychosocial and behavioural changes as a result of mass hysteria, economic burden, and financial losses, in addition to its high infectivity and the increased mortality rates. Method: Published articles regarding to mental health related to the COVID-19 outbreak and other previous global infections have been considered and reviewed. Comments: The pervasive fear of COVID-19, named as "coronaphobia," has resulted with a slew of psychiatric manifestations in people from all walks of life. It has affected people from all the point of life, resulting in a variety of psychiatric issues such as anxiety, post-traumatic stress disorder (PTSD), fear and uncertainty, panic attacks, depression, obsessive compulsive disorder, xenophobia, and racism. Collective concerns have an impact on daily behaviours, the economy, prevention strategies, and decision-making by policymakers, health organisations, and medical centres, which can weaken COVID-19 control strategies and lead to increased morbidity and mental health needs on a global level.
Differences Between Methicillin-susceptible Versus Methicillin-resistant Staphylococcus aureus Infections in Pediatrics

Background: The epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) has changed in recent years. The present article is intended to establish differences between clinical, laboratory and imaging findings and outcomes of MSSA and MRSA infections, as well as among subgroups of infection such as skin and soft tissue infection, osteoarticular, bacteremia or pneumonia in a pediatric population from Bogota, Colombia. Methods: Retrospective cohort study using clinical records of patients under 18 years of age treated at the participating centers in Bogota, Colombia, between 2014 and 2018. The first positive S. aureus culture was studied. MSSA and MRSA were compared. The χ2 test, Fisher exact test, and Kruskal-Wallis test were calculated, and the statistical significance was presented using the difference and its 95% CI. Results: Five hundred fifty-one patients were included; 211 (38%) corresponded to MRSA and 340 (62%) to MSSA for a total of 703 cultures. A significantly higher probability of having an MSSA infection than MRSA was found in patients with previous heart disease (3.3% vs. 0.5%), neurologic disease (5.9% vs. 2.5%), recent major surgeries (11% vs. 5%) or who has an implanted device (11% vs. 4%). In contrast, in severe MRSA infections (bacteremia, osteoarticular infections and pneumonia), a higher rate of complications was seen (admission to the pediatric intensive care unit, mechanical ventilation and vasoactive support), and in osteoarticular MRSA, more than 1 surgery per case was seen (89% vs. 61%). Laboratory results and mortality were similar. Conclusions: MRSA was associated with a more severe course in bacteremia, osteoarticular infections and pneumonia. Some classical risk factors associated with MRSA infections were found to be related to MSSA. In general, with the exception of skin and soft tissue infection, there was an increased risk of pediatric intensive care unit admission and mechanical and inotropic support with MRSA in a pediatric population.
Determination of the Effects of Different Aqueous Ozone Doses and Temperature on Germination and Seedling Development of Vetch Seeds

ABSTRACT Various effects of ozone treatment on seed germination and development are known. This feature of ozone has gained more importance in recent years. On the other hand, it is reported that ozone used in excessive amounts causes adverse effects. The method of application of ozone and the results obtained vary according to the material used. In this study, two different vetch species (hairy vetch and common vetch), for 30 minutes four different ozone doses application [control (0.40 g/m3), 1.60 g/m3, 2.80 g/m3, 4.00 g/m3] and three different temperatures (10, 15 and 20 °C) were examined. As a result of applications; germination rate, radicle length, plumule length, seedling length, seedling fresh weight, seedling dry weight and vigor index values were calculated. It was determined that plumule length, seedling length, seedling fresh weight and vigor index values of the species were affected by ozone doses and temperature applications. Also, it was determined that the cultivar ˟ temperature ˟ ozone dose interaction had significant effects on the length of the radicle (P < 0.01) and the seedling fresh weight (P < 0.05). According to the results of the study; it has been determined that the applications of ozonized water up to 2.80 g/m3 positively affect the germination, radicle and seedling development of hairy vetch and common vetch seeds compared to the control. Besides, it was observed that the highest dose, 4.00 g/m3 dose, negatively affected the same parameters. It was found that the effect of temperature and ozone dose applications were significant on germination and seedling development.
On the mode II popcorn effect in thin packages

Experiments were carried out using P-TQFP-176 packages to study the mode II popcorn effect in thin packages. The doming of the package backside was measured as a function of time and temperature. The measurements were performed using a line projection method. An "accelerated" increase in the doming was found to correlate with the onset of the package crack propagation. It was shown that when a constant critical doming angle is reached, package cracks begin to propagate toward the surface. This critical doming angle was found to be temperature independent between 170/spl deg/C and 215/spl deg/C. Furthermore the development of the package doming with time was described by a simple model based on the moisture diffusion from molding compound and die-attach material in combination with a bimaterial plate theory. The water content of the die-attach layer after preconditioning was calculated from the model and it was found to be in good agreement with the results of a three dimensional finite element simulation.
Exploring Core Addiction Themes and Their Resolution in Recovery Narratives Using the “Life as a Film” (LAAF) Procedure

Abstract Though narrative studies have provided important insights on addiction and recovery, social desirability and self-protective factors may limit the richness and relevance of standard “life story” accounts. In marginalized populations, the “Life as Film” (LAAF) procedure has proved useful for addressing these concerns. Building on this literature, the present study adopted the LAAF approach with an objective to undercover features distinguishing addiction and recovery narratives. Achieving this objective serves to model addiction and recovery in terms of narrative constructions and reconstructions. Thirty-two participants, active or in recovery from addiction, were recruited, producing LAAF narratives of their lives. Interviewees completed a Recovery Inventory (RI), to compare narrative material with recovery outcomes. Content analysis revealed three structures: (1) a high prevalence Core Plot, featuring interpersonal conflict, negative arousal and self-management via substance use; (2) an Addiction Narrative, with themes of victimization, betrayal, compulsion, and escapist protagonists; and (3) a Recovery Narrative, with themes of redemption, self-mastery, caring, unity, and healer protagonists. Findings build on existing literature, suggesting narrative processes through which core conflicts become embedded in addiction stories and resolved in recovery stories. These processes indicate psychological pathways to positive change, carrying implications for interventions.
Preparatory School Teachers’ Self-Directed Online Professional Development

This case study investigates how teachers render digital professional development in digital environments by interviewing with three preparatory school English language teachers voluntarily engaged in online professional development. In order to examine their process of teacher learning in online settings, we drew on Self-Determination Theory (Deci & Ryan, 2012) regarding the motivation as to how they engage and learn in the course of online professional development. An exploratory approach was adopted based on the interviews, and the motivational factors of the participants together with how they exploit technology were presented in three different cases. The study revealed that all the teachers were intrinsically motivated, and the need for developing competence, exercising autonomy, and assessing relatedness were key motivational reasons behind their online professional learning. Instagram, MOOCs, YouTube and websites were the online sources mentioned by the participants when they turn to the Internet for help. The discussion focuses on implications of this study for encouraging language teachers to engage in online professional development drawing on self-determination theory.
Merchants’ adoption of mobile payment in emerging economies: the case of unorganised retailers in India

ABSTRACT A substantial body of literature shows that in addition to increased convenience, mobile payments may result in greater efficiency and contribute to digital and financial inclusion. Although researchers have paid a lot of attention to individual adoption of mobile payment, few studies investigate mobile adoption by businesses, especially unorganised businesses in developing countries. To address this research gap, we use an exploratory grounded theory approach to examine unorganised retailers in urban India. Using 56 semi-structured interviews with merchants, we highlight an emerging mobile payment ecosystem that includes technology value, regulatory bodies, non-regulatory bodies, and merchant dispositions. The data highlight power asymmetry in this ecosystem and show that time-varying interactions among its components determine merchants’ behaviour and resulting (non-) adoption. We find that not only are Indian regulatory bodies the most powerful influencers in the diffusion of this technology; they are also important market actors. This study provides insights into the process of technology adoption by unorganised businesses in India. Moreover, this study sheds light on the important link unorganised retailers create between businesses and bottom-of-the-pyramid consumers, as well as between the state and its marginalised citizens, thereby confirming that such retailers are indispensable partners in economic growth and technology-driven inclusion.
Toward a Better Understanding of the Associations Among Different Measures of Father Involvement and Parenting Alliance

The variety of measurement methods used in fathering research to assess fathers’ involvement makes it difficult to summarize what we know about paternal involvement and its correlates and antecedents. Aiming to shed light on the potential consequences of using different measures of paternal involvement, this study examined: (a) the associations among three measures of father participation in parental activities, namely self- and mother-reported questionnaires and a father-completed time diary, and (b) their respective associations with a well-documented predictor of father involvement, i.e., parenting alliance. The sample included 80 parental couples with a 6-month-old child. Although moderate associations were found among measures of father involvement, only the maternal and paternal questionnaires were associated with parenting alliance. These results suggest that time diaries and questionnaires tap into different aspects of father involvement that can have distinct correlates and determinants. Better acknowledgment of the diverging results attributable to the use of different measurement approaches of father involvement is needed.
Improvements of Testing Procedures for Concrete Coefficient of Thermal Expansion

The coefficient of thermal expansion (CTE) of concrete has a significant effect on the performance of portland cement concrete pavement. Concrete with a higher CTE is more prone to cracking, additional warping, and spalling. To improve PCC pavement performance, several districts of the Texas Department of Transportation (TxDOT) currently limit the CTE of concrete. To support this policy, efforts have been made to improve the accuracy and repeatability of the testing procedures for CTE. The current AASHTO Test Method TP 60 has been evaluated, its shortcomings identified, and improvements made. The improvements include CTE determination from regression analysis of temperature and displacement measurements. The effects of a number of variables on concrete CTE were investigated. The effect of the rate of heating and cooling is negligible. Concrete age and specimen size also have a negligible effect. Coarse aggregate content in the concrete mix has an effect on the test results. This test procedure was used to evaluate coarse aggregates from 32 sources in Texas. The results show that coarse aggregate type has a significant effect on concrete CTE. The proposed testing procedure for concrete CTE provided more accurate results than the AASHTO TP 60. TxDOT plans to implement this test procedure and to develop appropriate steel design standards for continuously reinforced concrete pavement and other construction-related requirements such as different curing methods for concrete with varying CTEs. This implementation should result in better concrete pavement performance.
The Differential Impact of the Experiential- Entrepreneurial Learning Method on the Entrepreneurial Intentions of Higher Education Students

This study has comparatively examined the differential impact of the experiential-entrepreneurial learning method on the entrepreneurial intentions of students against the traditional entrepreneurial-teaching method of the course in Entrepreneurship and Small Business Management in Wollo University, Ethiopia. The research design appropriated was a quasi-experimental non-equivalent comparison-group design. The data for the study were drawn from 202 prospective graduating students. An entrepreneurial-intentional questionnaire (EIQ) was used to collect the data. To test the impact of course intervention, ANCOVA and SEM_path analysis were employed. As the findings indicated, a significant mean difference in the entrepreneurial intention and its antecedents were obtained between the experiential-entrepreneurial method and the traditional entrepreneurial-teaching method group of the study participants. The relationships of variables included in the theory of planned behavior (TPB) have been affected by the two teaching-learning methods univocally. The findings have practical implications and recommendations for the teaching-learning processes of entrepreneurship in higher education.
Assessment of potentiality of known bacterial blight resistant genes against Xanthomonas oryzae pv. oryzae pathotypes exist in Bangladesh

Bacterial blight (BB) caused by X. oryzae pv. oryzae is a destructive disease of rice and causes 30-50% losses to rice depending on the outbreak. Development BB resistant rice varieties have long been considered as one of the most effective approach to control the disease. However, the durability of host resistance is breaking down due to the change of pathotypes of X. oryzae pv. oryzae globally. Pathotypic analyses of 239 X. oryzae pv. oryzae Bangladeshi isolates on Near Isogenic Lines (NILs) containing resistance (R) gene (s) revealed the existence of eight pathotypes of X. oryzae pv. oryzae. Among eight pathotypes, pathotypes IV and V were considered as major comprising maximum number of isolates, (30.13% and 23.01%, respectively), whereas pathotype VIII considered as minor consisting only 2.51% of total isolates. Pathotype, I showed highest virulence or aggressiveness compatible with all NILs, whereas pathotype VIII exhibited lowest virulence to these NILs. Bacterial blight resistant genes viz. Xa1 (75.00%), Xa11 (62.50%) and Xa21 (50.00%) showed resistance to most of the pathotypes while Xa4 performed worst as compared to all others R-genes. In pyramid lines, IRBBB63 (Xa5+Xa7+Xa13) and IRBB57 (Xa5+Xa7 +Xa21) showed resistance reaction and IRBB61 (Xa4+Xa5+Xa7), IRBB60 (Xa4+Xa5+Xa13+Xa21), IRBB54 (Xa5+Xa21), and IRBB53 (Xa4+Xa21) showed susceptible reaction to X. oryzae pv. oryzae pathotypes. These results collectively indicated the deployment of Xa1, Xa11, Xa4, Xa5, Xa7, Xa13 and Xa21 either alone or in combination against BB would be a best choice for the development of BB resistant rice varieties in Bangladesh.
Discriminative Feature Mining Based on Frequency Information and Metric Learning for Face Forgery Detection

Face forgery detection has received considerable attention due to security concerns about abnormal faces generated by face forgery technology. While recent researches have made prominent progress, they still suffer from two limitations: a) the learned features supervised by softmax loss are insufficiently discriminative, since the softmax loss fails to explicitly boost inter-class separability and intra-class compactness; b) hand-crafted features are unable to effectively mine forgery patterns from frequency domain. To address the two problems, this paper proposes a novel frequency-aware discriminative feature learning framework. Specifically, we design an innovative single-center loss which compresses mere intra-class variations of natural faces while encouraging inter-class differences between natural and manipulated faces in the embedding space. Supervised by such a loss, more discriminative features can be learned with less optimization difficulty. As for frequency-related features, a frequency feature adaptively generated module is developed to capture frequency clues in a data-driven manner. Besides, to better fuse the features of both RGB domain and frequency domain, this paper devises a fusion module based on positional correlation of features. The effectiveness and superiority of our framework have been proved by extensive experiments and our approach achieves state-of-the-art performance in both in-dataset and cross-dataset evaluation.
TEACHERS’ SELF-EFFICACY BELIEFS AND OPINIONS ABOUT DISTANCE EDUCATION DURING THE COVID-19 PANDEMIC

This study investigated teaching self-efficacy beliefs and opinions about distance education of teachers in Turkey who switched to distance education during the COVID-19 pandemic. 758 teachers from Turkey completed an online questionnaire comprising demographic information questions, likert type scale items on self-efficacy for distance education, closed-ended questions addressing teachers' opinions about distance education, and an open-ended question enabling teachers express their experiences with distance education. Data analysis included descriptive statistics, independent samples t-tests, and content analysis. The analysis showed that teachers' beliefs in their own abilities in fulfilling the requirements of distance education, such as organizing effective learning environments and preparing different evaluation activities were not at a high level. The education they received, the active use of technology before the pandemic period and the type of school they work in have effects on teachers' self-efficacy towards distance education. The low number of students attending the live classes negatively affected their motivation. Furthermore, teachers thought that current instructional materials on the platform were not sufficient for students to be successful. However, teachers believed that their experiences in distance education during the pandemic increased their efficiency in education. Most participants received sufficient support from the school administration, but not from parents during this period. Students' lack of computers and/or internet and systemic errors were among the main problems encountered by the teachers regarding the distance education system. In the study, suggestions were made to make distance education more effective. © 2021. All Rights Reserved.
Collection and Advice on Basketball Field Tests—A Literature Review

We conducted a review to collect the validated basketball-specific physical field tests and to provide practical advice for their appropriate selection and application. A comprehensive electronic literature search was performed via three electronic databases (PubMed, GoogleScholar, and SportDiscuss). Results of 93 studies provided recommendations for seven test packages and eighteen individual tests that have already been validated for basketball players. Although there is a lack of standardized, widely, and systematically used test protocols for testing the fitness levels of basketball players, standardized, normative data from NBA Combine Testing and other basketball-specific tests have the potential to help coaches compare their players with elite basketball players. Our review indicated that agility and reactive agility are fundamental skills in basketball; however, linear sprinting ability should not be considered a determining factor of success for basketball players. Finally, the countermovement jump test can help experts monitor fatigue, loss of explosive force, and interlimb asymmetries. In general, we found that identifying and developing a talented player is a complex task and requires experts from different fields, including trainers, coaches, performance- and movement analyzers, and physiotherapists. We found that during the testing of basketball players, experts always have to normalize their data with anthropometric measures for valid results. Most importantly, although experts always need to define an aim of testing and should follow the protocol of the chosen test, they also have to be open to making adjustments if the actual circumstances require it.
Seed location mapping using RTK GPS

The potential use of a real-time kinematics (RTK) GPS receiver for seed mapping with a high level of accuracy was investigated. High-accuracy seed mapping can potentially be used in weed control and plant-specific crop management. A four-row Salvo 650 vacuum planter was retrofitted with an RTK GPS receiver. Four seed detector sensors (one per planting unit) were mounted directly above the planter shoes. These sensors detected the seeds as they fell through seed tubes. Two low-cost single-board computers were used to acquire data in real time and display it in the tractor cab. The first computer was interfaced to the RTK GPS unit to determine seed location and forward speed. The second computer was interfaced to a display unit mounted in the cab. The first computer obtained the GPS time and UTM coordinates every second and stored them with a reference time (time tag). This computer also monitored the seed detector sensors, time-tagged the seeds from each unit, and stored the information in memory. The second computer monitored the first computer and reported the planter’s performance through the display unit mounted in the tractor cab. Field tests were conducted to check the performance of this planter over two growing seasons. The first year test results indicated a need to control the sensitivity of the seed detector sensors used for seed detection. The second year tests showed that the improved system performed very well. The differences between the actual plant and the seed map generated by the RTK GPS based planter were in the range of 30 to 38 mm.
