Mindfulness in Teaching and Job Burnout: The Mediating Role of Self-Efficacy

Job burnout is a problem characterized by physical and mental problems caused by intense working conditions. In recent years, many teachers on a global scale have stated that they have experienced job burnout. It is known that many teachers who experience job burnout report sleep, fatigue, desire to quit work, low level of professional satisfaction and wellbeing. Although it is known that there are negative relationships between mindfulness, self-efficacy in classroom management, and job burnout, no research has been encountered to examine these concepts in the context of education. This study examined the mediating role of classroom management self-efficacy in the relationship between classroom mindfulness and teacher burnout.The research sample consists of 288 teachers, 185 women (64.2%) and 103 men (35.8%). In the preliminary analysis, for detecting multicollinearity Harmon’s Single Factor Test and for normality Skewness and Kurtosis were tested. The goodness of fit values of the tested model was found as χ2 / df=1.17, CFI=. 99, TLI=. 99, GFI=. 99 and RMSEA=. 03. Since the path between mindfulness and job burnout in teaching is significant in the model, it is understood that self-efficacy in classroom management is a partial mediator in the relationship between mindfulness in teaching and job burnout. Mindfulness in the teaching profession is believed to play a key role in both self-efficacy in classroom management and burnout in the profession.
The dichotomy between strong and ultra-weak magnetic fields among intermediate-mass stars

Abstract Until recently, the detection of magnetic fields at the surface of intermediate-mass main-sequence stars has been limited to Ap/Bp stars, a class of chemically peculiar stars. This class represents no more than 5-10% of the stars in this mass range. This small fraction is not explained by the fossil field paradigm that describes the Ap/Bp type magnetism as a remnant of an early phase of the star-life. Also, the limitation of the field measurements to a small and special group of stars is obviously a problem to study the effect of the magnetic fields on the stellar evolution of a typical intermediate-mass star. Thanks to the improved sensitivity of a new generation of spectropolarimeters, a lower bound to the magnetic fields of Ap/Bp stars, a two orders of magnitude desert in the longitudinal magnetic field and a new type of sub-gauss magnetism first discovered on Vega have been identified. These advances provide new clues to understand the origin of intermediate-mass magnetism as well as its influence on stellar evolution. In particular, a scenario has been proposed whereby the magnetic dichotomy between Ap/Bp and Vega-like magnetism originate from the bifurcation between stable and unstable large scale magnetic configurations in differentially rotating stars. In this paper, we review these recent observational findings and discuss this scenario.
Perfect transfer of multiple excitations in quantum networks

We present a general formalism to the problem of perfect state transfer (PST), where the state involves multiple excitations of the quantum network. A key feature of our formalism is that it allows for inclusion of nontrivial interactions between the excitations. Hence, it is perfectly suited to addressing the problem of PST in the context of various types of physical realizations. The general formalism is also flexible enough to account for situations where multiple excitations are ``focused'' onto the same site.
Minocycline Ameliorates LPS-Induced Learning and Memory Impairment By Inhibiting Microglia and Astrocytes Activation in the Hippocampus

INTRODUCTION : Many studies support the notion that neuroinflammation involving glial cells may be the fundamental pathogenic event that lead to brain damage and degeneration in Alzheimer’s disease (AD). The effects of minocycline on glial cells activation in the lipopolysaccharide (LPS) rat model is studied here. MATERIALS AND METHODS : Fifty adult male Sprague Dawley rats were split into five groups: control, LPS, LPS-treated with minocycline 25 mg/kg, LPS-treated with minocycline 50 mg/kg, and LPS-treated with memantine 10 mg/kg. For two weeks, rats were treated with minocycline and memantine intraperitoneally daily, while were injected with LPS intraperitoneally once on day 5. Morris water maze (MWM) test was performed to evaluate the learning and working memory behaviour. Immunohistochemistry and Western blot were performed to measure ionized calcium-binding adaptor molecule 1 (Iba-1) and glial fibrillary acidic protein (GFAP) expressions in the hippocampal tissue. RESULTS: LPS injection caused significant learning and working memory deficits (p<0.05) as well as increased expressions of Iba-1 and GFAP (p<0.05), indicating microglia and astrocytes activation, respectively. Minocycline treatment significantly improved learning and working memory performance (p<0.05) and reduced microglia/astrocytes activation (p<0.05) in a dose-dependent manner, similar to the effect of memantine. CONCLUSIONS: Our results suggest that minocycline modulates LPS-induced microglia and astrocytes activation as well as improves learning and working memory comparable to memantine. Thus, minocycline may have a preventive-therapeutic effect in diseases involving neuroinflammation such as AD.
Epidemiological, Clinical, Etiological and Therapeutic Aspects of Angioedema in Dakar, Senegal

Derm Abstract Angioedema (AE) is an uncommon condition which can be life-threatening in case of laryngeal involvement or during anaphylactic shock. The studies concerning AE are rare in sub-Saharan Africa. Ours aims were to determine the epidemiological-clinical characteristics and etiological factors of AE and to describe the management modalities in Dakar. We conducted a descriptive and analytical study range from March 1st to August 31st 2017 in two dermatology departments (Institut d’Hygiene Sociale, Aristide Le Dantec Hospital) and one cardiology department (Aristide Le Dantec Hospital). We included all patients presented with AE and who consented to participate in the study. whom had histaminergic AE. We found a statistically significant relationship between urticaria and histaminergic AE (p = 0.03). Prick tests were positive in 13 cases with clinical concordance in 8 cases. The determination of IgE specific trophallergens allowed us to highlight a food allergy in 2 patients. For histaminergic AE cases, treatment was based on anti-H1 exclusively in 29.73% (n = 11) or associated with oral corticosteroids in 35.13% (n = 13). For cases of bradykinic-mediated AE, there was a change in medications along with a clinical follow up.
Dynamic Discouraged Borrowers

In this paper we provide new evidence on the dynamic evolution of discouraged borrowers over a long-time period. Using a cross-country panel of firms from the Eurozone, we first uncover the characteristics of discouraged borrowers, their evolution over the business cycle as well as the underlying reasons driving borrower discouragement. Then, as a second step, we link the outcome of both term loan and credit line applications for firms that declared to be discouraged in the past. We show that half of the ex-discouraged borrowers obtained a term loan and/or a credit line once they applied, suggesting that those borrowers are conscious that their credit risk profile had improved. among In panel show descriptive statistics and univariate comparison of difference in means of borrowers and that for a loan distinguishing in panel B, descriptive statistics and univariate comparison of difference in means of discouraged borrowers and firms that for a loan distinguishing by the outcome of the application process in got everything, loan scaled and credit the crisis.
IMPROVED PROTOCOL FOR IN VITRO PROPAGATION OF GLOXINIA ( SINNINGIA SP .)

: An efficient and reproducible protocol for in vitro multiplication of gloxinia has been developed. Leaf discs used as explants were surface sterilized with HgCl 2 (0.1%) and Bavistin (2%). Sterilized explants were cultured on MS media augmented with BAP (2 mg/l) and NAA (0.5 mg/l) which proved most appropriate for shoot induction. Sprouted shoots were sub cultured on medium with different concentrations of BAP which resulted in varying degrees of multiple shoots. Increasing the concentration of BAP resulted in reduction in number of shoots per explant. Maximum proliferation of shoots was observed in MS medium augmented with BAP (2.0 mg/l) and NAA (0.5 mg/l) within 2 weeks and average number of shoots per explant was 7.3. The in vitro raised shoots of gloxinia were successfully rooted in MS media fortified with NAA and IBA. Rooted plantlets could be successfully established in potting mixture of cocopeat and sand (1:1).
CHARACTERISTICS OF STUDENTS' MATHEMATICAL PROBLEM SOLVING ABILITIES IN OPEN-ENDED-BASED VIRTUAL REALITY GAME LEARNING

This research is motivated by the problem-solving ability of students is still low, and the teaching materials used cannot be studied independently. The purpose of this study was to determine students' profiles about students' problem-solving abilities seen from indicators of choosing and implementing the problem-solving strategies to solve mathematical and outside mathematics using open-ended-based virtual reality games. A virtual reality game through open-ended-based learning media is made with the concept of moving the situation of learning mathematics in the real world into a virtual world displayed through a computer. This research used a qualitative method with a case study design. The research instrument used is a question of mathematical problem-solving ability through open-ended-based and interview transcripts. The research subjects were six eighth grade Junior High School students consisting of two students with high knowledge, two with moderate knowledge, and two with common knowledge. The result showed that students have different mathematical problem-solving abilities from each indicator, namely 1) identifying the adequacy of data for problem-solving, 2) making mathematical models from everyday situations or problems, 3) selecting and implementing strategies to solve math and math problems outside of using virtual reality games through open-ended based.
epsilon-pseudoclassical model for quantum resonances in a cold dilute atomic gas periodically driven by finite-duration standing-wave laser pulses.

Atom interferometers are a useful tool for precision measurements of fundamental physical phenomena, ranging from the local gravitational-field strength to the atomic fine-structure constant. In such experiments, it is desirable to implement a high-momentum-transfer “beam splitter,” which may be achieved by inducing quantum resonance in a finite-temperature laser-driven atomic gas. We use Monte Carlo simulations to investigate these quantum resonances in the regime where the gas receives laser pulses of finite duration and derive an e-classical model for the dynamics of the gas atoms which is capable of reproducing quantum resonant behavior for both zero-temperature and finite-temperature noninteracting gases. We show that this model agrees well with the fully quantum treatment of the system over a time scale set by the choice of experimental parameters. We also show that this model is capable of correctly treating the time-reversal mechanism necessary for implementing an interferometer with this physical configuration and that it explains an unexpected universality in the dynamics.
High temperature x-ray diffraction studies on antiferroelectric and ferroelectric phase transitions in (Pb1−xBax)ZrO3(x=0.05,0.10)

We have carried out high temperature x-ray diffraction studies on (Pb1−xBax)ZrO3(PBZ) to correlate the large thermal hysteresis (∼100 °C for x=0.05) and irreversibility (for x=0.10) of the antiferroelectric (AFE)–ferroelectric (FE) phase transition observed in dielectric measurements with structural changes. It is shown that for both the compositions, the sequence of phase transitions during heating is orthorhombic antiferroelectric (AO) to rhombohedral ferroelectric (FR) and then to cubic paraelectric (PC). The wide phase coexistence region (∼80 °C for x=0.05 and ∼160 °C for x=0.10) and the arrest of the FR to AO transition for x=0.10 during cooling strongly indicate first order character of the AO–FR transition. It is shown that the transformation strains associated with the AO to FR transition increases with Ba2+ concentration from a value of 0.6% for x=0 to 0.9% for 0.10. Similarities of the AO–FR transition in PBZ with nonthermoelastic martensitic transformations are pointed out. The FR to PC transit.
Estimating the changing burden of disease attributable to high fasting plasma glucose in South Africa for 2000, 2006 and 2012.

BACKGROUND Worldwide, higher-than-optimal fasting plasma glucose (FPG) is among the leading modifiable risk factors associated with all- cause mortality and disability-adjusted life years (DALYs) due to the direct sequelae of diabetes and the increased risk for cardiovascular and chronic kidney disease. OBJECTIVES To report deaths and DALYs of health outcomes attributable to high FPG by age and sex for South Africa (SA) for 2000, 2006 and 2012. METHODS Comparative risk assessment methodology was used to estimate the burden attributable to high FPG. A meta-regression analysis was performed using data from national and small-area studies to estimate the population distribution of FPG and diabetes prevalence. Attributable fractions were calculated for selected health outcomes and applied to local burden estimates from the second South African National Burden of Disease Study (SANBD2). Age-standardised rates were calculated using World Health Organization world standard population weights. RESULTS We estimated a 5% increase in mean FPG from 5.31 (95% confidence interval (CI) 5.18 - 5.43) mmol/L to 5.57 (95% CI 5.41 - 5.72) mmol/L and a 75% increase in diabetes prevalence from 7.3% (95% CI 6.7 - 8.3) to 12.8% (95% CI 11.9 - 14.0) between 2000 and 2012. The age-standardised attributable death rate increased from 153.7 (95% CI 126.9 - 192.7) per 100 000 population in 2000 to 203.5 (95% CI 172.2 - 240.8) per 100 000 population in 2012, i.e. a 32.4% increase. During the same period, age-standardised attributable DALY rates increased by 43.8%, from 3 000 (95% CI 2 564 - 3 602) per 100 000 population in 2000 to 4 312 (95% CI 3 798 - 4 916) per 100 000 population in 2012. In each year, females had similar attributable death rates to males but higher DALY rates. A notable exception was tuberculosis, with an age-standardised attributable death rate in males double that in females in 2000 (14.3 v. 7.0 per 100 000 population) and 2.2 times higher in 2012 (18.4 v. 8.5 per 100 000 population). Similarly, attributable DALY rates were higher in males, 1.7 times higher in 2000 (323 v. 186 per 100 000 population) and 1.6 times higher in 2012 (502 v. 321 per 100 000 population). Between 2000 and 2012, the age-standardised death rate for chronic kidney disease increased by 98.3% (from 11.7 to 23.1 per 100 000 population) and the DALY rate increased by 116.9% (from 266 to 578 per 100 000 population). CONCLUSION High FPG is emerging as a public health crisis, with an attributable burden doubling between 2000 and 2012. The consequences are costly in terms of quality of life, ability to earn an income, and the economic and emotional burden on individuals and their families. Urgent action is needed to curb the increase and reduce the burden associated with this risk factor. National data on FPG distribution are scant, and efforts are warranted to ensure adequate monitoring of the effectiveness of the interventions.
The current research trend of artificial intelligence in language learning: A systematic empirical literature review from an activity theory perspective

Although the field of artificial intelligence (AI) has rapidly developed, there has been little research to review, describe, and analyse the trends and development of empirical research on AI-supported language learning. This paper selected and analysed 25 empirical research papers on AI-supported language learning published in the last 15 years. These empirical studies were analysed using the activity theory from seven constituents: tool, subject, object, rules, community, division of labour, and outcome. A key contribution of this paper is the use of activity theory to illustrate the dynamic interactions and contradictions between the seven elements. AI-supported technology as a mediating tool demonstrated some effectiveness in language learning but needs further improvement in the use of language for communication and collaborative design. We argue that teachers’ intervention and configuration of AI-supported language learning in the pedagogical design plays an important role in the effectiveness of learning. More research is needed to explore the use of AI-supported language learning in the classroom or the real-life learning context. Implications for practice or policy: Research on AI-supported language learning should view teacher and students as active agents in interacting with technology and making transformations in real life learning situations. More research should focus on productive dialogue and communication in AI-supported language learning with collaborative design. A mixed module of AI-supported language learning and formal teacher instruction should be incorporated in pedagogical design.
THE UV ESCAPE FRACTION OF HIGH-REDSHIFT GALAXIES

We investigate the degree of opacity of high-redshift galaxies to outgoing UV photons. Using multi-band images of high-redshift galaxies and HST photometry we show that in average no more than 4% of the continuum UV ux can escape (3 limit) from each galaxy. This result is compatible with observations of low-redshift galaxies, but is in contradiction with some recent results based on spectroscopy of z 3 galaxies.
Contrasting Climatic Trends of Atmospheric River Occurrences Over East Asia

Atmospheric rivers (ARs) are increasingly recognized as a major driver of hydrological cycles, and are projected to increase around the world under a changing climate. However, the long‐term trends of ARs over East Asia (EA) remains less elucidated. Here we fill the gap by developing a longest‐ever archive of EA ARs, and examine its role in determining spatiotemporal precipitation variability over EA. We find contrasting changes in AR occurrences, with more frequent ARs in low latitudes but less in high latitudes during the period 1950–2020. The “dipole” pattern of decadal changes in AR occurrences is dictated by atmospheric dynamics (i.e., winds) in the north but thermodynamics (i.e., moisture) in the south. The reduced AR occurrences explain 49% of decreased annual precipitation in northern China, while more AR‐related precipitation is observed in southern China. Our results provide new insights into regional hydroclimate over EA by connecting it with large‐scale weather systems.
Signals induced by charge-trapping in EDELWEISS FID detectors: analytical modeling and applications

The EDELWEISS-III direct dark matter search experiment uses cryogenic HP-Ge detectors Fully covered with Inter-Digitized electrodes (FID). They are operated at low fields (< 1 V/cm), and as a consequence charge-carrier trapping significantly affects both the ionization and heat energy measurements. This paper describes an analytical model of the signals induced by trapped charges in FID detectors based on the Shockley-Ramo theorem. It is used to demonstrate that veto electrodes, initially designed for the sole purpose of surface event rejection, can be used to provide a sensitivity to the depth of the energy deposits, characterize the trapping in the crystals, perform heat and ionization energy corrections and improve the ionization baseline resolutions. These procedures are applied successfully to actual data.
Modeling the dynamical friction timescale of a sinking satellite

When a satellite galaxy falls into a massive dark matter halo, it suffers from the dynamical friction force which drags it into the halo's center, where it finally merges with the central galaxy. The time interval between entry and merger is called the dynamical friction timescale (Tdf). Many studies have been dedicated to deriving Tdf using analytical models or N-bodysimulations. These studies have obtainedqual- itative agreements on how Tdf depends on the orbital parameters, and the mass ratio between the satellite and the host's halo. However, there are still disagreements on deriving an accurate form for Tdf. We present a semi-analytical model to predict Tdf and we focus on interpreting the discrepancies among different studies. We find that the treatment of mass loss from the satellite by tidal stripping dominates the behavior of Tdf. We also identify other model parameters which affect the predicted Tdf.
Opportunities to Stimulate the Critical Thinking Performance of Preservice Science Teachers Through the Ethno-Inquiry Model in an E Learning Platform

The acquisition of critical thinking (CT) as one of the 21st century skills is categorically crucial. Therefore, the effective training of CT skills in terms of learning activities needs detailed exploration. This study applied the ethno-inquiry model in an e-learning platform and evaluated its impact on the CT skills of preservice science teachers (PSTs). The experimental design employed the randomized pretest-posttest control design involving 62 PSTs as participants, divided equally into an experimental and control group. Participants’ CT skills were assessed using essay tests. The tests focused on the CT skills dealing with analysis, inferencing, evaluation, and decision-making indicators. The CT scores were analyzed using parameters of the average pretest-posttest. The learning implementation effects were calculated using a paired t test and analysis of covariance (ANCOVA) at the significance level of . 05. The findings demonstrated that the CT scores for the experimental group increased from the less critical to the critical level. This result was better than that of the control group. Similarly, the improvement of individual CT performance was better in the experimental group. Based on the results of the analysis, the t test and ANCOVA of both groups confirmed that the ethno-inquiry model had a significant effect on the CT skills of participants. The results thus provide convincing evidence of the essential roles of the ethno-inquiry model in science learning and it is therefore recommended that the model be implemented in science classes.
Estimation of Some Genetic Parameters of Some Productive Traits of local and Turkish Awassi Sheep

This study was carried out at the ruminant research station of the General Commission for Agricultural Research / Ministry of Agriculture (in Abu Ghraib 20km west of Baghdad) from December 2018 to December/2020. The research included 200 records belonging to the Turkish and local Awassi sheep herd to estimate some genetic parameters (heritability, genetic and phenotypic correlations, and evaluate the Best Linear Unbiased Prediction (BLUP) for some productive traits (total milk production, lactation period, birth weight Weaning weight, average weight gain). The estimate of heritability were for the productive traits 0.19, 0.12, 0.25, 0.29, 0.25, respectively. The genetic correlation for the effective traits ranged between positive and highly significant (P<0.01) and not significant, as its coefficient ranged between 0.81 and 0.15. The phenotypic correlation of the productive traits ranged between positive and highly effective (P<0.01) and was not significant, as the coefficient ranged between 0.87 and 0.12 for the above effective characteristics. The values of the Best Linear Prediction (BLUP) for traits ranged 12.376. The lowest of which is -0.641.
