The effects of teacher mental health and job burnout on child development

In this paper, we assess the impacts of the incidence of teachers’ depression symptoms and job burnout on children’s early development. To this aim, we use a sample of one thousand children 18-36 months of age at baseline, attending public center-based childcare in eight large cities in Colombia between 2013 and 2014. We measure depression symptoms using the CESD-10 scale and job burnout with the MBI-ES instrument for 267 teachers. We assess children’s receptive language, school readiness, self-regulation, working memory, and socioemotional development. The identification strategy exploits the longitudinal nature of the dataset to estimate an added-value specification that controls for baseline developmental outcomes and instrumental variables to address potential endogeneity biases. The results indicate that teacher depression has a negative impact on socio-emotional development only, while teacher job burnout has sizeable negative effects on cognitive development, selfregulation and socio-emotional development. These effects seem to be driven by changes in the warmth and sensibility of teacher-child interactions rather than by the type and frequency of pedagogical activities in the classroom.
The Thermal Stability of the Naphthalene Sulfonic and Naphthalene Disulfonic Acids under Geothermal Conditions: Experimental Results and a Field-Based Example

The thermal stability of six naphthalene sulfonic acid tracers (2,6-NDS, 2,7-NDS, 1,5-NDS, 1,6-NDS, 1-NSA, 2NSA) was investigated using a one-pass, continuous flow, fluid rock interaction simulator. The pore fluid utilised was pH modified, low pressure separator brine from Nga Awa Purua power station at Rotokawa with 100 μg/kg of the six tracers added. The simulator contained crushed and clean fragments of greywacke sourced from well RK24. The temperature range investigated was 270C – 390C Results show that 2,6 and 2,7-NDS remain stable to about 340C while 1,5-NDS begins to degrade as early as 280C. 1,6-NDS shows degradation beginning at 330C. For the NSA, the concentration of 1-NSA increases until 330C after which, it begins to degrade while 2-NSA concentration increases until 380C. The results are interpreted using three reaction mechanisms: desulfonation, isomerisation and naphthalene pyrolysis. A field-based example of tracer degradation is described from the Rotokawa geothermal field. A suite of NDS tracers was injected and returns were not found after a monitoring period of one year. Reanalysis, in light of the experimental results, showed the presence of 2-NSA which was not one of the original tracers injected. These results provide field-based evidence of the thermal degradation of naphthalene sulfonic acid tracers and imply the use of tracer mixtures for use as geothermometers.
Presenting an entrepreneurial developmental model Iran Public Libraries Using the Creativity and Psychological Empowerment of Employees

At the present time, employees’ innovative thoughts and ideas can be assumed to represent the origin of big changes in organizations. The present study aimed to investigate the relationship of the perceived organizational support and organizational creative climate with entrepreneurial development among the library employees. Creativity and psychological empowerment were examined as mediators. The sample of the study included 410 employees of Khuzestan Province Public Library Institution who were selected by random stratified sampling method and responded the organizational creative climate, perceived organizational support, psychological empowerment, organizational creativity questionnaires and also the entrepreneurial behavior inventory. For analyzing the data, in addition to use of descriptive methods (mean, Standard Deviation and correlation matrix), structural equation model (SEM) was used to check the proposed model, with the help of AMOS 21. Mediating relationships were tested in the proposed model by bootstrap method. Fit indices such as GFI, CGI, and RESMA have necessary quorum indicating that the proposed model fit with data. Results of the study showed the significance of all direct paths of perceived organizational support and organizational creative climate towards the entrepreneurial development. The insignificant paths were deleted, the model was modified and corrected. Fit indices of structural equation model showed the suitable fitness of modified model. Meanwhile, results of indirect relationships confirmed the significance of these relations. Summarizing the key findings, able people develop new ideas because of their sense of competence and mastery of the environment and go beyond learning to produce and develop self-awareness. Employees who are self-confident and motivated face challenges and seek a better alternative solution.
Private Non-smooth ERM and SCO in Subquadratic Steps

We study the differentially private Empirical Risk Minimization (ERM) and Stochastic Convex Optimization (SCO) problems for non-smooth convex functions. We get a (nearly) optimal bound on the excess empirical risk with O ( N 3 / 2 d 1 / 8 + N 2 d ) gradient queries, which is achieved with the help of subsampling and smoothing the function via convolution. Combining this result with the iterative localization technique of Feldman et al. [FKT20], we achieve the optimal excess population loss for the SCO problem with O (min { N 5 / 4 d 1 / 8 , N 3 / 2 d 1 / 8 } ) gradient queries. Our work makes progress towards resolving a question raised by Bassily et al. [BFGT20], giving first algorithms for private ERM and SCO with subquadratic steps. In a concurrent work Asi et al. [AFKT21] gave other algorithms for private ERM and SCO with subquadratic steps.
Prevalence and Predictors of Hypertension Among Adult Traders in Ibadan Metropolis, Oyo State, Nigeria

Hypertension, also known as high or raised blood pressure, is a condition in which the blood vessels have persistently raised pressure, putting them under increased stress. It is a major risk factor for chronic heart disease, stroke, and coronary heart disease and also a major cause of mortality and morbidity globally. This study aimed to examine the prevalence and predictors of hypertension among adult traders in Ibadan metropolis, Oyo State, Nigeria. A descriptive cross-sectional survey was employed in this study. A semi-structured questionnaire was used to collect the data. The simple random sampling method was used to select Ibadan North West Local Government Area among the five urban local government areas in Ibadan metropolis. All the six (6) markets under this local government were included in the study. All the eligible adult traders that consented were interviewed using a semistructured questionnaire.

Reports measurements of the attenuation induced by trees on satellite-like paths over a wide range of frequencies (1-4 GHz). These measurements can be used to evaluate the comparable performance of mobile satellite systems at different elevation angles and over a wide frequency range. They can also provide a further insight into the applicability of the empirical formula on vegetation effects quoted in the CCIR report 236-6 (1986). >
A Quantitative Synthesis of Recent Research on the Effects of Teaching and Learning With Technology on Student Outcomes

To estimate the effects of teaching and learning with technology on students’ cognitive, affective, and behavioral outcomes of learning, 138 effect sizes were calculated using statistical data from 20 studies that contained a combined sample of approximately 4,400 students. The mean of the study-weighted effect sizes averaging across all outcomes was . 30 ( p < .05), with a 95-percent confidence interval (CI) of . 004 - . 598. This result indicates that teaching and learning with technology has a small, positive, significant ( p < .05) effect on student outcomes when compared to traditional instruction. The mean study-weighted effect size for the 13 comparisons containing cognitive outcomes was . 39, and the mean study-weighted effect size for the 60 comparisons that focused on student affective outcomes was . 208. On the other hand, the mean study-weighted effect size for the 30 comparisons that contained behavioral outcomes was -. 154, indicating that technology had a small, negative effect on students’ behavioral outcomes. The overall study-weighted effects were constant across the categories of study characteristics, quality of study indicators, technology characteristics, and instructional/teaching characteristics.
An Improved Prediction System of Students’ Performance Using Classification model and Feature Selection Algorithm

Prediction on students’ academic performance is a subject or situation under consideration of interest for both students and educational institutions at large. This is a strong emerging issue to be widely studied to determine the factors affecting students' performance in the sense of data mining. Respondent students’ internal and external factors are students’ demographic state, socio-economic condition, parental educational status, extra-curricular activities, teaching quality, and students’ learning behavior that aims to predict performance predominantly. We use WEKA (Waikato Environment for Knowledge Analysis) tools to accomplish our research. This paper proposes the feature selection algorithm and classification model to develop student performance prediction system. The performance of the proposed methods is compared with another feature selection algorithm that is based on classification model. This paper aims to provide machine learning classifier algorithms with selected attribute to get better accuracy and comparable different feature selection algorithms because of its feature selection algorithm which is used to select the most valuable features. In the feature selection algorithm, WrapperSubsetEval method with Random Forest classification is better than other feature selection method and other classification algorithm to predict students’ performance.
INVESTIGATION OF THE REMOVAL OF REACTIVE BLUE 220 DYE BY GUM EXTRACTED FROM TARAMIND SEEDS

In this study, gum was successfully extracted from tamarind seeds (gum) and used as a material for the removal of reactive dye (Reactive Blue 220-RB220). The performance of decolorization and COD reduction of gum was investigated using the one-factor-at-a-time method. The factors include pH, mixing time, agitating speed, color concentration, and gum concentration. Under optimal conditions, color and COD removal efficiency of gum was roughly 74.4% and 83.3%, respectively. These results indicate that gum is a “green” and “eco-friendly” coagulant and has great potential for application in textile dyeing wastewater treatment.
Graffiti and Perceptions of Safety: A Pilot Study Using Photographs and Survey Data

Past research has demonstrated that incivilities, including graffiti, play a strong role in determining attitudes about safety and crime in local areas. This research was a pilot project that utilized both photography and standard quantitative survey research techniques to examine the impact of graffiti on perceptions of safety. We used photographs of graffiti and survey results to demonstrate that graffiti was related to perceptions of safety in local neighborhoods. More importantly, we also found that graffiti was not a unidimensional construct in terms of its impact on attitudes concerning safety. The research presented here established that reactions to graffiti vary widely based on the type of graffiti and, to some extent, differ by individual characteristics and victimization experiences. That is, different categories of graffiti, as developed by analysis of survey results associated with photographs of graffiti, evoke various levels of concern over safety. This research suggested that attempts to classify graffiti and reactions to it as a uniform phenomenon may be misguided.
A risk management model to assess safety and reliability risks

Evaluating project proposals with respect to safety and reliability objectives is extremely complex. Several tangible as well as intangible factors need to be considered. Also, most often these factors are difficult to measure objectively because of their nature and the lack of factual data and information. In addition, they involve uncertainties and risk. The project managers need to enumerate systematically all potential risk factors affecting the safety and reliability objectives of the project, determine the consequences and the impact of their severity, assess the likelihood of the occurrence of these consequences, and select the best course of action to contain and control risks in order to meet the specified project objectives. Develops such a framework by integrating system hazard analysis with the core elements of the risk management process (RMP) to assess potential risks and to evaluate response actions to control and manage the identified risks to satisfy the predetermined safety and reliability objectives.
THE EFFECT OF FOLIAR APPLICATION WITH ORGANIC AND INORGANIC PRODUCTS ON THE BIOCHEMICAL QUALITY INDICATORS OF HIGHBUSH BLUEBERRY (VACCINIUM CORYMBOSUM L.)

Foliar fertilization is applied quite frequently in combination with soil fertilization. The objective of this study was to evaluate the influence of two foliar organic fertilizers and one chemical on the biochemical quality of fruit of highbush blueberry (Vaccinium corymbosum L.). The experiment was performed on a farm in the meadow Argeș, in 2020 on a three-year plantation and was presented in a randomized block design, with three repetitions and four fertilization treatments:control (untreated), Poly-Feed 19–19–19 + ME (10 kg/ha), Algacifo 3000 (2 L/ha) and ERT 23 Plus (1 L/ha), repeated four times at every 10-14 days, from the formation of the bud to the beginning of fruit ripening. The blueberry varieties studied were: ‘Blueray’, ‘Duke’, ‘Elliott’ and ‘Hannah’s Choice’. Data were recorded on the following biochemical quality indicators: total dry matter content, soluble dry matter, total titratable acidity, sugar content, vitamin C, total anthocyanin content and polyphenols. The study showed that organic fertilizers had a superior effect on the biochemical quality of the fruit than the chemical one.
The Rayleigh-Taylor Instability in Thin Films

The Rayleigh-Taylor instability is investigated both analytically and numerically. Overall, the focus of the report is to not derive the mathematical formulation that brings for the thin film equation, but it is rather to discuss the overall dynamics of the thin-film displacement, ζ. A literature review was conducted to discuss the historical papers that first investigated this problem both theoretically and experimentally. We will discuss the linear problem analytically, with a corresponding discussion based in fourier analysis. Then, a numerical treatment is given for both the linear and nonlinear version of the governing equations.
Analysis of Burnout Syndrome in Healthcare Professionals

Introduction: Burnout Syndrome is an important problem that affects healthcare professionals to a greater extent than other workers. It has been estimated that approximately a 50% of physicians suffer from this syndrome. It is a problem that affects doctor’s well-being that can cause health problems on those professionals. Consequences of this syndrome not only affect the physician but also, a doctor affected by this syndrome is more likely to make medical errors and it also makes it harder to achieve the patient’s adherence to treatment. Materials and Methods: To check which factors can be linked to the onset of the syndrome, we have performed a study based on collecting data by a survey sent to Spanish doctors. This survey was divided in two parts, first one containing questions related to sociodemographic variables that we considered might be linked to the syndrome and second one, with the questions of the Maslach Burnout Inventory. Results: Then we proceeded to the statistical analysis of the obtained data, concluding that prevalence of this syndrome remains similar compared to previous studies. Conclusion: It was also concluded that the difficulty of the computer systems that professionals use, as well as the time physicians spend with their patients in relation with the time they spend doing tasks in their computers also effects on the onset of Burnout Syndrome.
Efficacy of a Final Lab Practicum and Lab Reports for Assessment in a Fundamentals Electric Circuits Laboratory

In a fundamental electrical engineering laboratory course, the traditional team based approach to laboratory structure with two or more members per lab team was not as effective for teaching basic laboratory skills and knowledge as a lab structure that allowed students to perform laboratory exercises individually throughout the semester. The laboratory report was insensitive and insufficient to measure the difference in the laboratory abilities and knowledge from these two groups. In order to assess the students' laboratory knowledge and abilities, it was necessary to develop a new assessment instrument that would be sufficient for this purpose. The students' performance on the final laboratory practicum exam provided an effective and verifiable objective metric with sufficient specificity to differentiate between the traditional team based and solo participation lab groups. Students who performed their laboratory exercises individually during the semester showed noticeable improvement in their ability to apply rudimentary laboratory skills and knowledge to basic circuits analysis applications in their final lab practicum scores. The study was performed over five consecutive semesters with 160 students sub-divided into control (traditional lab teams) and solo groups. Students in the control group performed the weekly laboratory exercises in lab teams of two or more while students in the solo group worked independently. The solo group exhibited statistically significant higher scores on the final lab practicum as compared to the control group; however, the lab report was not sufficiently sensitive to distinguish these differences. The results of this study indicated that students must be fully engaged in all laboratory exercises to thoroughly and properly learn and retain the skills and knowledge required to perform basic fundamental circuit analysis. The employment of an adequate and verifiable assessment instrument with requisite sensitivity to measure these laboratory knowledge and skills was essential to corroborate adherence to these laboratory objectives.
Web-based Learning Management System Considerations for Higher Education

Coinciding with the development and growth of the Internet, there has been a dramatic increase in the application of the Learning Management System (LMS) in higher education. Currently, university and college campuses must compare each LMS to ensure that the system meets the requirements and demands of the institution. Therefore, the purpose of this study is to review and discuss the important concepts and findings from research on LMS regarding higher education. In addition, five categories of LMS features on higher education are discussed, including (1) transmitting course content; (2) evaluating students; (3) evaluating courses and instructors; (4) creating class discussions; and (5) creating computer-based instructors. After discussing and reviewing the research, this study provides several recommendations and a model of development and design of LMS for future implementation.
Stream Channel Concept Applied to Waterflood Performance Calculations For Multiwell, Multizone, Three-Component Cases

The Higgins-Leighton technique for estimating waterflood performance was expanded to include the calculation of fluid production and injection for a multi-well, multi-zone system with asymmetrical drainage areas. This 2-dimensional, analytical method is based on the computer solution of streamlines, shape factors, waterflood performance by channels, and well-zone-field production combinations. The flow regime for each injector-producer pair in the system is represented by a series of channels whose sides are bounded by streamlines. Each channel may have a unique value for porosity, water saturation, and permeability. The channels are divided into equal volume cells to permit approximation of Buckley-Leverett linear displacement, with radial flow occurring through the cells adjacent to the producer and injector, and linear flow through the remaining cells. Initial conditions may include gas saturation for partial depletion. Streamline positions are generated from the solution of the flow potential in the Laplace equation for steady-state flow of 2 fluids of unit mobility in a uniform bed of constant porosity, water saturation, and absolute permeability.
High-resolution simulation of film cooling with blowing ratio and inclination angle effects based on hybrid thermal lattice Boltzmann method

A series of high-resolution simulations on film cooling with varying blowing ratios and inclination angles are carried out by using in-house code based on hybrid thermal lattice Boltzmann method. Three blowing ratios ranging from 0.2 to 0.8 and four inclination angles from 15? to 60? are chosen for the simulations. The evolutionary mechanism of coherent structure in three domains of film-covering region is studied from the view of space and time. Besides, the influencing mechanism of blowing ratio and inclination angle on flow and heat-transfer features of film cooling is uncovered. Results show that hairpin vortex, hairpin packet and quasi-stream-wise vortex appearing in rotating domain play a key role in heat-transfer process of film cooling. The strong ejection, sweep and vortex rotation resulted from these vortices enhance the convective heat transfer. It is also found that the size of coherent structure varies significantly with blowing ratio and its integral form shows a strong dependence on inclination angle. Moreover, inclination angle of coolant jet has a significant impact on turbulence fluctuation intensity. The influence of blowing ratio on the attachment of coolant film and film-cooling performance is more obvious than that of inclination angle. It is believed that all of these are related closely to the variation of stream-wise and wall-normal jet velocity in the case of various blowing ratios and inclination angles.
