Supporting Novice K-2 Teachers’ Self-Efficacy for Literacy: Early Literacy Teacher Induction for Rural Schools

ABSTRACT This study explored the year-long development of 159 (N = 159) novice K-2 teachers’ self-efficacy for literacy instruction, within a literacy-specific induction initiative with sixteen high-need, predominantly rural school districts. Findings reveal novice teachers’ self-efficacy for literacy instruction grew significantly throughout the year. Teachers’ satisfaction with specific induction supports in the multi-pronged initiative held various relationships with literacy self-efficacy at the middle and end of the year. The presence of supplemental, school-based supports had no moderating impacts on literacy self-efficacy. Teachers’ licensure status held various moderating influences on literacy self-efficacy throughout the year. Implications for supporting novice teachers’ self-efficacy for literacy instruction are discussed. Results add to the limited research examining how novice teachers’ self-efficacy for literacy instruction develops over time in rural, high-need schools.
The Ambivalent Mesenchyme-Pleomorphic Hyalinising Angiectatic Tumour

Pleomorphic hyalinising angiectatic tumour (PHAT) is an infrequently discerned, soft tissue, mesenchymal, spindle-shaped cellular neoplasm of uncertain cellular lineage initially scripted by Smith et al in 1996 and is contemplated as a neoplasm of intermediate malignant potential [1]. The exceptional, mesenchymal lesion is frequently cogitated within subcutaneous tissue and is composed of pleomorphic, spindle-shaped cells and ectatic blood vessels encompassed by hyalinised stroma and lack of mitosis [1,2].
Effect of Oil Viscidity on Optimal Demulsion Frequency in Pulse Electric Field

By establishing the vibration kinetics model of latex particle in oil under pulse electric field,the characteristics and conditions of latex particle's parametrically excited nonlinear vibration were studied.And then,the optimal demulsion frequency of latex particle was obtained under pulse electric field.In experiment,results showed that the value of optimal demulsion frequency and swing of resonance particle decreased with the increase of oil viscosity.In theory,swing-frequency characteristic relationship of vibrating particle obtained by model explained that oil viscosity could have effect on the optimal demulsion frequency and the reason that optimal demulsion frequency deviated from natural frequency of particle vibration.
Continuing Development of Metal-Loss Severity Criteria, Including Width Effects

The emergence in the early 1970s of what about a decade later became the first release of ASME B31G began the development and evolution of criteria to assess the severity of metal-loss defects. Motivated by the desire to reduce the conservatism embedded in B31G, the late 1980s saw the release of Modified B31G, with that same report also introducing RSTRENG, which quantified “riverbottom” effects. The desire to avoid excessive conservatism in their application to higher-strength Grades gave rise to alternative criteria for such applications. PCORRC appeared in 1997, with early versions of DNV RP-F101 and British Gas’ LPC-1 criteria following shortly thereafter. It has since become evident for isolated smooth-bottomed features that in addition to feature length and depth, its width can be a factor, as can its planar shape, and through-thickness profile. This paper builds on insight gained from the prior work, presenting and validating a Level 1 failure criteria for isolated metal-loss features. The defect-free term for this Level 1 criterion relies on the Zhu-Leis criterion for defect-free pipe failure. That criterion is coupled to a recalibrated defect term analogous to PCORRC, whose extension to include the effects of width is considered. The resulting Level 1 criterion is validated in reference to full-scale tests of pipe with metal-loss, which include a mix of real corrosion and flat-bottomed machined features. These tests consider Grades from Gr B to X100, a wide range of diameters and thicknesses, and in many cases the effect of width. Finite element results are used to illustrate the role of width. Benchmarked against almost 80 full-scale tests it is shown that this new approach affects a reduction in conservatism. At the same time, it provides clear benefits in regard to reduced predictive scatter, as well as a reduction in required maintenance, and the scope of features that must be considered in field-digs.

Comparison of microsatellites and SNP markers in genetic diversity level of two Scots pine stands

Scots pine (Pinus silvestris), is one of the dominant species in Poland and one of the main forest tree species in northern and central Europe. This species is of great economic importance. The Scots pine is highly adaptable to changing environmental conditions. A number of ecotypes have been characterized and the formation of these ecotypes are related with development of different phenotypic characteristics; morphological, physiological, and ecological. Molecular studies, based on DNA polymorphism, have been used for more than 20 years to analyze the genetic diversity of the Scots pine population. The most popular are microsatellite markers due to the fact of wide availability and high polymorphism. However, the use of these markers is also associated with certain limitations, due to complex mutation models or high incidence of homoplasia. These features are prompting scientists to look for alternative types of markers such as, for example, SNP. In our study we conducted a comparison of the basic parameters of genetic variability of two Scots pine stands (25 and 24 trees in each) for 20 SNP markers and 4 microsatellite markers. For the 20 SNP loci the observed heterozygosity (Ho) was equal to 0.34 for both stands and the expected heterozygosity (He) was equal to 0.34 for the first stand and 0.37 for the second. No statistically significant genetic distance was observed between them. For the microsatellite markers observed heterozygosity (Ho) was 0.81 and 0.74, and the expected heterozygosity (He) was equal to 0.85 and 0.85 respectively for the stands, and similarly no statistical significant genetic distance was observed. Literature data of different genetic markers showed the higher informativeness of randomly chosen microsatellites than single nucleotide polymorphism (SNP) markers for study population differentiation. But some analyzes confirm that the appropriate number of SNP markers can be more informative for population structure inference.
Efektivitas Pelatihan “Let’s Learn to Pause & Breathe” untuk Menurunkan Kesulitan dalam Meregulasi Emosi pada Siswa Kelas XII SMA X Gresik

This training is intended to help increase students 'mindfulness so that it can help reduce students difficulties in regulating emotions. The aspect of mindfulness used in this training is based on aspects of the five facet mindfulness questionnaire (FFMQ) (Baer et al., 2006), namely nonreactivity to inner experience, observing, acting with awareness, describing/ labeling, and nonjudging of experience. Measurement of students' level of difficulty in regulating emotions using aspects of difficulties in emotion regulation (Roemer & Gratz, 2004), namely nonacceptance of emotional responses, difficulties engaging in goals-directed behavior, impulse control difficulties, lack of emotional awareness, limited access to emotion regulation strategies and lack of emotional clarity. The results of the training show that the mindfulness training can help reduce the level of difficulty regulating emotions experienced by students (significance value is less than 0.05).
Maternal mental health and child nutritional status in an urban slum community in Bangladesh

Objective: Maternal poor mental health might diminish her capability of taking adequate care of her child, resulting in negative impact on child’s nutrition. This study aims to determine the association between maternal mental health and child nutritional status.Methods: It was a cross-sectional study carried out in 264 mother-child pairs in an urban slum area of Bangladesh. Self-Reporting Questionnaire-20 (SRQ-20) was used for assessing maternal mental health. SRQ-20 score ≥7 was considered as common mental disorders (CMD). Anthropometric measurements were done for assessing child nutritional status. Results: The prevalence of maternal CMD was 46.2%. Maternal CMD was associated with poorer child feeding practice (p<0.001), poorer hygiene practice (p<0.001), poorer preventive care service use (p=0.016) and suffering from diarrheal disease (p=0.049). The prevalence of stunting, wasting and underweight were 44.3%, 18.2% and 33.7%, respectively. Poorer child feeding practice was associated with wasting (p=0.004) and underweight (p<0.001) but not with stunting. Poorer hygiene practice and suffering from diarrheal disease were associated with stunting and underweight but not with wasting. In multivariate analysis, maternal CMD was associated with child underweight (adjusted OR=2.25, 95% CI=1.15-4.43). Association between maternal CMD and wasting found in bivariate analysis that disappeared after multivariate analysis. No association was observed between maternal CMD and stunting in this study.Conclusions: Maternal mental health affects child nutritional status through child feeding practice, hygiene practice and preventive care use. Interventions to address mental health of mothers in child nutrition programmes might contribute to improve child nutritional status.
BETTER WITH OZONE, OR NOT? AN IN-VIVO STUDY OF OZONE THERAPY AS A PRE-TREATMENT BEFORE FISSURE SEALANT APPLICATION.

Objectives: The aim of the study was to evaluate clinical achievements of ClinproTMSealant and Teeth mate F-1 fissure sealants with or without ozone treatment as well as retention, marginal discoloration, marginal adaptation and caries formation under in-vivo conditions. Materials and Methods: The study was carried out on 166 patients whose ages differs between 9-12 and 3 different groups were formed above them according to split mouth technique, in order to evaluate clinical achievements of fissure sealants with or without ozone treatment. Group 1: ClinproTMSealant and Teethmate F-1 were applied on a total of 104 first lower permanent molar teeth which were randomly selected from 52 patients. Group 2: ClinproTM Sealant and ClinproTM Sealant following ozone treatment were applied on 112 randomly selected teeth of 56 patients. Group 3: Teeth mate F-1 and Teeth mate F-1 following the ozone treatment were applied on 116 first lower permanent molar teeth which were randomly selected from 58 patients. Based on the modified USPHS criteria, the impacts on general achievement, retention, marginal fit, marginal discoloration and caries formation on occlusal surfaces were evaluated in 3rd,6th,12th,18th months. Chi-Square Test and Fisher’s Exact Test were used for analyses of the data. Results: In Group 1; Clinpro™Sealant showed higher clinical success rates in all observation periods. Considering marginal adaptation and retention, Clinpro™Sealant group was statistically significantly different in 18th month observations. In group 2 and group 3, there was not statistically significantly difference (p>0.05) between control and experimental groups but clinical success rates of Clinpro ™ Sealant and Teetmate F-1 with Ozone Treatment were higher than the same groups without ozone pretreatment during all observation periods. Conclusion: It was determined that, ClinproTMSealant yielded more successful results than the Teethmate F-1 under in-vivo conditions. Although there wasn’t any statistically significantly difference between Group 2 and Group 3 in which Ozone as a pretreatment method before performing fissure sealant was considered, the Ozone pretreatment method’s success rates were higher clinically according to Bravo, Alpha and Charlie Scores. It seems that performing Ozone Therapy before applying fissure sealant is a successful method for preventing pit and fissure sealants, clinically.
Dietary Supplementary of Modified Si-jun-zi Granule Promotes Intestinal Development and Enhances Mucosal Immunity of Weaned Rex Rabbits

Background: Early-weaned in Rex rabbits and other animals is associated with the development and immunity of intestine. This article was aimed to investigate the potential benefits of a dietary supplementation, modified Si-jun-zi granule (M-SJZG), on enhancing immunity of small intestinal mucosa and promoting intestinal development of weaned Rex rabbits. Results: In the present study, we found that dietary supplementation with 2% modified Si-jun-zi granule decreased the diarrhea frequency and mortality due to early-weaned, and significantly increased the average daily gain; the length and relative weight of intestine; the concentration of immunoglobulin in serum and SIgA in intestinal mucus. Additionally, the activity of lipase was raised by dietary Si-jun-zi granule addition. However the activities of ALT, ALP and AST in serum were obviously decreased. Compared with the un-supplementation control group, the ratio of villi length to crypt depth and the expression of tight junction protein(zonula occludens-1, Claudin-1 and Occludin) and Glucose transporter (re-combinant Sodium/Glucose co-transporter 1 and recombinant Glucose transporter 2) in jejunum were raised. In addition, Moreover early development of intestine and the injury of intestinal mucosa induced by early-weaning also could be improved.Conclusions: This study indicated that modified Si-jun-zi granule has protective effects on diarrhea induced by early-weaning through enhancing immunity of small intestine mucosa and promoting intestinal development.
Evaluating Convolutional Neural Networks for COVID-19 classification in chest X-ray images

Coronavirus Disease 2019 (COVID-19) pandemic rapidly spread globally, impacting the lives of billions of people. The effective screening of infected patients is a critical step to struggle with COVID-19, and treating the patients avoiding this quickly disease spread. The need for automated and scalable methods has increased due to the unavailability of accurate automated toolkits. Recent researches using chest X-ray images suggest they include relevant information about the COVID-19 virus. Hence, applying machine learning techniques combined with radiological imaging promises to identify this disease accurately. It is straightforward to collect these images once it is spreadly shared and analyzed in the world. This paper presents a method for automatic COVID-19 detection using chest Xray images through four convolutional neural networks, namely: AlexNet, VGG-11, SqueezeNet, and DenseNet-121. This method had been providing accurate diagnostics for positive or negative COVID-19 classification. We validate our experiments using a ten-fold cross-validation procedure over the training and test sets. Our findings include the shallow fine-tuning and data augmentation strategies that can assist in dealing with the low number of positive COVID-19 images publicly available. The accuracy for all CNNs is higher than 97.00%, and the SqueezeNet model achieved the best result with 99.20%.
Determination of Appropriate Fertilizer Rate for Forage and Seed Yields of Fodder Beet (Beta vulgaris) in the Central Highland Areas of Ethiopia

The study was conducted to determine the optimum level of chemical and farm yard manure fertilizer mixture for fodder beet ( Beta vulgaris) production and to evaluate the effect of different mixed fertilizer rates on agronomic performance of fodder beet in the central highlands of Ethiopia. The experiment was designed in a factorial arrangement of four chemical fertilizer rates (0, 5/13, 10/23, 15/33, kg N/P 2 O 5 ha -1 ) and four farm yard manure fertilizer rates (0, 3, 6 and 9 t ha -1 in dry matter basis) in a randomized complete block design with three replications. Data on plant survival rate, plant height, leaf yield, tuber yield, total forage yield and seed yield of fodder beet were collected and subjected to analysis of variance procedures of statistical analysis system (SAS) using general linear model to compare treatment means. The result showed that the interaction between inorganic and organic fertilizers application levels had significant (P<0.05) effect on all the aforementioned agronomic traits at Meraro. The establishment performance of fodder beet was very poor both at Holetta and Jeldu using direct seeding method of planting in the first year of production. But, using seedlings raised at nursery as a planting material at Holetta and Jeldu improved the plant survival rate by 52% and 49% respectively. Unlike at Holetta and Jeldu, establishment performances of fodder beet at Meraro using seeds as a direct planting material was promising and found to be an appropriate establishment method. The result showed that application of 10/23 kg N/P 2 O 5 ha -1 + 9 t FYM ha -1 fertilizers as a mixture gave the highest plant survival rate (81.9%), plant height (30.3 cm), leaf DM yield (2.7 t ha -1 ), tuber DM yield (10.3 t ha -1 ) and total DM yield (13.0 t ha -1 ) while the lowest values of the above traits were recorded from the control treatment. Application of fertilizers mixture at a rate of 10/23 kg N/P 2 O 5 ha -1 + 9 t FYM ha -1 increased the survival rate, plant height, leaf DM yield, tuber DM yield and total DM yield by 34, 57, 286, 296 and 294% over the control treatment. But, the highest seed yield (3.0 qt ha -1 ) was obtained by applying the highest level of fertilizer mixture (15/33 kg N/P 2 O 5 ha -1 + 9 t FYM ha -1 ) which gave 900% seed yield advantage over the control treatment. Therefore, applying 10/23 kg N/P 2 O 5 ha -1 + 9 t FYM ha -1 and 15/33 kg N/P 2 O 5 ha -1 + 9 t FYM ha -1 fertilizer mixture were found to be the optimum fertilizers mixture rate for forage and seed yields of fodder beet. The study led to the conclusion that the combined application of the organic and inorganic fertilizers resulted in higher yields than sole application of each nutrient source. Therefore, this preliminary result recommends using FYM alongside with mineral fertilizers to increase forage and seed yields of fodder beet. However, further experimental research works should be carried out for more seasons and locations to assess the consistence of this finding.
Langmuir hydrogen dissociation approach in radiolabeling carbon nanotubes and graphene oxide

Abstract Carbon-based nanomaterials have piqued the interest of several researchers. At the same time, radioactive labeling is a powerful tool for studying processes in different systems, including biological and organic; however, the introduction of radioactive isotopes into carbon-based nanomaterial remains a great challenge. We have used the Langmuir hydrogen dissociation method to introduce tritium in single-walled carbon nanotubes and graphene oxide. The technique allows us to achieve a specific radioactivity of 107 and 27 Ci/g for single-layer graphene oxide and single-walled carbon nanotubes, respectively. Based on the analysis of characteristic Raman modes at 1350 and 1580 cm−1, a minimal amount of structural changes to the nanomaterials due to radiolabeling was observed. The availability of a simple, nondestructive, and economic technique for the introduction of radiolabels to single-walled carbon nanotubes and graphene oxide will ultimately expand the applicability of these materials.

Quarenteners vs. Cloroquiners: a framework to analyze the effect of political polarization on social distance stances

The worldwide COVID-19 pandemic has struck people’s lives overnight. With an alarming contagious rate and no effective treatments or vaccines, it has evoked all sorts of reactions. In this paper, we propose a framework to analyze how political polarization affects groups’ behavior with opposed stances, using the Brazilian COVID polarized scenario as a case study. Two Twitter groups represent the pro/against social isolation stances referred to as Chloroquiners and Quarenteners. The framework encompasses: a) techniques to automatically infer from users political orientation, b) topic modeling to discover the homogeneity of concerns expressed by each group; c) network analysis and community detection to characterize their behavior as a social network group and d) analysis of linguistic characteristics to identify psychological aspects. Our main findings confirm that Cloroquiners are right-wing partisans, whereas Quarenteners are more related to the left-wing. The political polarization of Chloroquiners and Quarenteners influence the arguments of economy and life, and support/opposition to the president. As a group, the network of Chloroquiners is more closed and connected, and Quarenteners have a more diverse political engagement. In terms of psychological aspects, polarized groups come together on cognitive issues and negative emotions.
