Evaluating the Effects of Adding Explicit Vocabulary Instruction to a Word-Problem Schema Intervention

Schema instruction improves word-problem solving for students with mathematics difficulty (MD; e.g., Powell et al., 2015); however, prior research suggests that students need word-problem-specific language comprehension in addition to schema knowledge to build word-problem models ( Fuchs et al., 2015, 2018). Students have general word knowledge (e.g., more, less) but require word-problem-specific word knowledge to solve word problems successfully (e.g., more than, less than; Kintsch & Greeno, 1985). Prior word-problem schema interventions have not provided explicit instruction in word-problem vocabulary to support students’ development of word-problem models. We aimed to determine if word-problem vocabulary instruction combined with schema instruction provided an advantage to word-problem solving for third-grade students with MD. We randomly assigned 75 third graders with MD to three conditions: Word-problem intervention with explicit vocabulary instruction (WP + V), word-problem intervention without explicit vocabulary instruction (WP-only), and business-as-usual intervention (BAU). Students in the treatment conditions received 22, 50-min lessons provided virtually in small groups. On a word-problem vocabulary measure, students in the WP + V condition significantly outperformed students in the WP-only (ES = 0.43) and BAU (ES = 0.83) conditions. On a word-problem measure, students in the WP + V condition outperformed students in the WP-only (ES = 0.08) and BAU conditions (ES = 0.43), although these were not statistically significant. These findings provide preliminary support for the benefits of incorporating explicit vocabulary instruction in a word-problem schema intervention; future research is needed to fully understand the effect of vocabulary instruction on word-problem outcomes.
On the Petersson norm of a Siegel-Hecke Eigenform of degree two in the Maass space.

The aim of this note is to give an identity relating the Petersson norm of a Siegel-Hecke eigenform F of degree 2 and even weight k contained in the Maass space to the value of the Hecke L-series Lf(s) at the point s = k (one unit right to the center of the critical strip) of the normalized Hecke eigenform/on SL2(Z) of weight 2k — 2, which corresponds to F under the Saito-Kurokawa lifting. This identity can easily be deduced from the work of Oda [11]—[13] and Kudla [6] when combined with the fact (proved by Zagier in [14]) that the Maass space in weight k and a certain subspace
A Study of Work Based Learning For Construction Building Workers

Work-based learning (WBL) is designed to improve the competence of participants. This study aims to apply the WBL and to develop attitudes, knowledge, skills, behaviors, and habits, which in turn can improve the competence of construction workers in the field to be sampled. This research was conducted on building construction workers in Medan City with 30 research subjects. The results showed that the evaluation of learning increased in phase I obtained the difference of the average score of 20.9 (the meeting I) and 25.50 (meeting II). The final result shows that the level of activity and competence increased significantly after WBL
Dietary Schizochytrium Microalgae Affect the Fatty Acid Profile of Goat Milk: Quantification of Docosahexaenoic Acid (DHA) and Its Distribution at Sn-2 Position

The objective of this study was to detect the influence of dietary Schizochytrium microalgae on milk composition, milk fatty acids, and milk sn-2 fatty acids in goat’s milk. Firstly, we could see that the fat content increased in low microalgae supplementation goat’s milk (LM, 15 g/day) and the lactose content decreased in medium microalgae supplementation goat’s milk (MM, 25 g/day) compared with control goat’s milk (C, 0 g/day). Moreover, the absolute concentration of the docosahexaenoic acid (DHA) of LM, MM, and high microalgae supplementation (HM, 35 g/day) goat’s milk was 29.485, 32.351, and 24.817 mg/100 g raw milk, respectively, which were all higher than that in the control goat’s milk with 4.668 mg/100 g raw milk. In addition, the sn-2 DHA content increased in MM and HM goat’s milk. However, the decreasing trend of the sn-2 DHA content was observed in LM goat’s milk. As for other fatty acids, the oleic acid (C18:1n9c) and linolenic acid (C18:3n3) content decreased and increased, respectively, in all experimental goat milk. Finally, an interesting phenomenon was found, which was that docosanoic acid (C22:0) and tetracosenic acid (C24:1) were only detected in test goat’s milk. Consequently, the phenomena of this study demonstrated that dietary Schizochytrium microalgae have an obvious effect on the fatty acid and sn-2 fatty acid profile of goat’s milk, and they provide an effective method to improve the content of goat’s milk DHA in practical production.
REVISITING MATHEMATICAL RESILIENCE AND ANXIETY AMONG SENIOR HIGH STUDENTS

Resilience is vital in recovering from mathematical anxiety since it gives motivation in pursuing despite obstacles and challenges. This study aimed to measure the mathematical resilience and anxiety of grade 11 students at Visayas State University-Main campus as well as to elucidate its relationship. Secondary data was used in this study from a current paper by Casinillo et al. (2020). Mean average, standard deviation, coefficient of variation, and Spearman rho correlation was employed to summarize and extract inference from the data. On average, the perception scores of students' levels of resilience and anxiety are 82.2 and 29.5, respectively. Results suggested that students are resilient and moderately anxious in learning mathematics. This implies that students are motivated even if they are facing some challenging problems in mathematics. On the other hand, students are somehow uneasy or experiencing a little worry in doing mathematical problems. Findings depicted that there is no significant relationship (p-value=0.4725) between the students' level of resilience and anxiety. This means to say that resiliency of students does not lessen the level of anxiety in learning mathematics. In that case, teachers must not only be focusing on the resiliency of their students but also on creativity, self-determination, and motivation, among others. Furthermore, to eliminate the anxiousness of students in facing mathematical problems, teachers must encourage and cultivate their interest in learning mathematics.
Clinical Behavior of the Gingival Margin following Conservative “Coronally Dynamic” Restorations in the Presence of Non-Carious Cervical Lesions Associated with Gingival Recession: A Pilot Study

Gingival recessions (GR) are often associated with the presence of non-carious cervical lesions (NCCL). The latter result in the disappearance of the cement–enamel junction (CEJ), with consequent difficulties both in measuring the recession itself and in performing root coverage techniques. The restoration of cervical lesions is consequently an important aspect in the treatment of GR, with the re-establishment of a “new” CEJ. This pilot study aimed to verify whether restorative therapy alone, with the execution of a restoration that mimics the convexity of the natural CEJ and thanks to a slight horizontal over-contour, can stabilize a clot in the intrasulcular site and consequently is able to change the position of the gingival margin in a coronal direction. In periodontally healthy patients, with a non-thin gingival phenotype, 10 GR-associated NCCL restorations were performed using a protocol inspired by concepts of prosthetic conditioning, with a progressively reduced convexity (“coronally dynamic restoration”) and de-epithelialization of the gingival sulcus. We observed that 70% of the treated teeth showed a reduction in crown length after 15 days (−0.267 mm), without an increase in probing depth. While considering the limitations of the sample and the need to evaluate the different parameters that can affect the result, the coronally dynamic restoration of NCCL with GR was able to influence the position of the gingival margin in a coronal direction.
Controversy Teaching Approaches: Model, Measure, and Teaching Applications

Controversies are a potentially powerful teaching tool in the management classroom enabling students to explore different perspectives on an issue and to develop their skills in areas such as critical thinking and communication. Controversy is implicit to learning and to leadership and management roles in workplaces where multiple opposing views inevitably exist. Prior research asserts that constructive controversy resolution skills are important to management students. This multipart study presents a model and measure of controversy teaching approaches and explores evidence of their reliability and validity using confirmatory factor analysis and correlations with relevant outcomes and measures. The three studies, with samples of management and leadership students across several U.S. institutions, provide initial evidence of the validity of the model and measure. Multiple perspectives and avoidance were found to be underlying dimensions of instructors’ observed approaches to teaching controversial topics. The controversy teaching approaches model and measure used in this study have potential to support instructional development for management educators, as well as further research on controversy teaching. This study also has practical implications for how instructors approach controversies in the classroom and may aid effective teaching and learning.
Flow and Thermal Field Measurements in a Combustor Simulator Relevant to a Gas Turbine Aeroengine

The current demands for high performance gas turbine engines can be reached by raising combustion temperatures to increase power output. Predicting the performance of combustor is quite challenging, particularly the turbulence levels that are generated as a result of injection from high momentum dilution jets. Prior to predicting reactions in a combustor, it is imperative that these turbulence levels can be accurately predicted. The measurements presented in this paper are of flow and thermal fields produced in a large-scale combustor simulator, which is representative of an aeroengine. Three-component laser Doppler velocimeter measurements were made to quantify the velocity field while a rake of thermocouples was used to quantify the thermal field. The results indicate large penetration depths for the high momentum dilution jets, which result in a highly turbulent flow field. As these dilution jets interact with the mainstream flow, kidney-shaped thermal fields result due to counter-rotating vortices that develop.
COVID-19 Pandemic: Assessment of Current Strategies and Socio-economic Impact

The coronavirus disease is a respiratory tract disorder which causes pneumonia-like symptoms in severe patients and mild flu-like symptoms in mild symptomatic cases first noticed in Wuhan, China. DNA sequencing and further analysis shows it to be 79% like the 2002 SARS-CoV and 50% like the 2012 MERS-CoV. It was also observed that the novel coronavirus’s spike protein was larger and very different from its previously known strains. For diagnosis, multiple strategies were developed and real time reverse-transcriptase-polymerase chain reaction (RT-PCR) technique was determined to be the best technique. The CT scan was also found effective majorly for the continuous assessment of the disease. Treatment strategies used in previous outbreaks were looked into and put to trial like convalescent plasma therapy. Vaccine development using various genetic engineering strategies are going on across the world. To contain the spread of the disease, countries with positive cases were put under lockdown to break the chain of spread. These lockdowns forced industries, offices, schools, religious places, stadiums, travel, and many more to close which impacted the economies of all the major countries. Lesser human interaction and more use of social media has impacted the social aspects of human life. Cases of domestic violence and mental stress increased among households. Economic stimulus package was announced by various countries to curb the socio-economic impact of the COVID-19 pandemic.
Transformational leadership effect on teacher performance in Asia: A meta-analysis

Transformational leadership is a leadership style that prioritizes commitment values, patterns, and performance to achieve organizational goals needed in the 21st century. This leadership style is widely applied in developing countries and has the best educational status in the world, such as in Finland and the United States. Researchers have recommended that transformational leadership is an important aspect of teacher performance; however, whether the effect varies across related studies and the robustness of the overall effect size remains unclear. A meta-analysis technique was used to synthesize the results from 65 independent studies and investigate the overall relationship between transformational school leadership and the three measures of teacher performance. This study found that, in terms of the average influence measure, transformational school leadership positively influenced teacher job satisfaction, commitment, and self-efficacy Keywords: Transformational leadership, teacher performance, meta-analysis
Long Term Comprehensive Evaluation of Temporal
and Spatial Variation of Water Quality in Chaohu
Lake, China

To clarify trends in water quality in Chaohu Lake, 480 surface water samples were collected monthly from 8 sampling sites in the eastern and western Chaohu Lake regions from 2016 to 2020. The content of dissolved oxygen (DO), permanganate index (COD Mn ), ammonia nitrogen (NH 3 -N), total phosphorus (TP), total nitrogen (TN), and Chlorophyll a (Chl-a) were analyzed, and the water quality of Chaohu Lake was comprehensively evaluated by a comprehensive nutrient status index method and a fuzzy clustering method. The average contents of TP and TN in Chaohu Lake decreased over time. The mean values of TP and TN ranged from 0.049 to 0.16 mg/L and 0.98 to 2.2 mg/L, respectively. The mean value of NH 3 -N decreased from 0.27 mg/L in 2016 to 0.098 mg/L in 2020. The mean value of COD Mn decreased by 22.96% compared with 2016. Based on the fuzzy clustering method and a comprehensive trophic state index, the water quality of the lake was increased from 2018 to 2020, and the comprehensive trophic state value decreased significantly, also indicating that the overall water quality of Chaohu Lake has improved since 2018. The results of this study could provide a reference for the prevention and control of water pollution in the Chaohu Lake Basin.
Exogenously Applied Proline Enhances Morph-Physiological Responses and Yield of Drought-Stressed Maize Plants Grown Under Different Irrigation Systems

The exogenous application of osmoprotectants [e.g., proline (Pro)] is an important approach for alleviating the adverse effects of abiotic stresses on plants. Field trials were conducted during the summers of 2017 and 2018 to determine the effects of deficit irrigation and exogenous application of Pro on the productivity, morph-physiological responses, and yield of maize grown under two irrigation systems [surface irrigation (SI) and drip irrigation (DI)]. Three deficit irrigation levels (I100, I85, and I70, representing 100, 85, and 70% of crop evapotranspiration, respectively) and two concentrations of Pro (Pro1 = 2 mM and Pro2 = 4 mM) were used in this study. The plants exposed to drought stress showed a significant reduction in plant height, dry matter, leaf area, chlorophyll content [soil plant analysis development (SPAD)], quantum efficiency of photosystem II [Fv/Fm, Fv/F0, and performance index (PI)], water status [membrane stability index (MSI) and relative water content (RWC)], and grain yield. The DI system increased crop growth and yield and reduced the irrigation water input by 30% compared with the SI system. The growth, water status, and yield of plants significantly decreased with an increase in the water stress levels under the SI system. Under the irrigation systems tested in this study, Pro1 and Pro2 increased plant height by 16 and 18%, RWC by 7 and 10%, MSI by 6 and 12%, PI by 6 and 19%, chlorophyll fluorescence by 7 and 11%, relative chlorophyll content by 9 and 14%, and grain yield by 10 and 14%, respectively, compared with Pro0 control treatment (no Pro). The interaction of Pro2 at I100 irrigation level in DI resulted in the highest grain yield (8.42 t ha–1). However, under the DI or SI system, exogenously applied Pro2 at I85 irrigation level may be effective in achieving higher water productivity and yield without exerting any harmful effects on the growth or yield of maize under limited water conditions. Our results demonstrated the importance of the application of Pro as a tolerance inducer of drought stress in maize.
Comparison of Health-Relevant Polyphenolic Component Content and Bioavailability of Bilberry (Vaccinium Myrtillus L.), Blueberry (Vaccinium Sect. Cyanococcus Rydb.) and Chokeberry (Aronia Melanocarpa (Michx.) Elliott)

The fruit-based dietary supplement business is flourishing, and many plant bioactive compounds exhibit beneficial effects on health. Polyphenols, including anthocyanins, proanthocyanidins, flavanols, phenolic acids and flavanols in bilberry, blueberry and chokeberry, are the bio-factors that determine the biological activities of the three berries. Many reports on phenolic compounds and their biological activities in berries have been published. Therefore, it is urgent to make a systematic comparison among them. We reviewed these scientific researches about phenolic substances including their compositions, contents and bioavailability from the bilberry, blueberry and chokeberry. On this basis, the phenolic compounds regarding monomer components and their contents in the three berries were systematically summarized. Variations of anthocyanidins within interspecies and different families were explained. Biological properties including biostability and bioavailability of anthocyanin and prospects for further study on berries were contained.
Molecular structure, hierarchical assembly and stimuli-responsive mechanics of tropoelastin and elastin biomaterials

The elastin polymer, assembled from its molecular precursor tropoelastin, is the dominant component of elastic fibers, which confer elasticity and structural integrity to skin, lung, connective and vascular tissue. Historically, elastin's dynamic nature has precluded traditional approaches such as X-ray crystallography to understand its detailed features. Solving tropoelastin's atomistic structure is key to characterizing elastin's complex biological function, disease-related mechanisms associated with mutations therein, and assembly process, to replicate natural function upon impairment. From the materials perspective, elastin-based materials display tunable thermal sensitivity, presenting opportunities to mimic and control these responsive features for biomedical applications. First, we develop and validate an elastic network model of tropoelastin based on smallangle X-ray scattering to realize near-equilibrium dynamics. We identify a geometrydriven lock-and-key mechanism implicated in cell binding and multi-molecular assembly. We introduce a constitutively quiescent domain to explain the effect of local stiffness perturbation on dynamics, reconciling the contradictory needs for overall structural flexibility and the organizational requirement of specific domains towards protein selfassembly. Second, we develop an atomistic model of tropoelastin and validate it against experimental data. We introduce artificial mutations to probe the function of key molecular regions and cutis laxa-associated mutations to study disease etiology. We reveal mechanisms behind variation in structure and hierarchical assembly based on molecular geometry, secondary structure, location and exposure of hydrophobic domains, and dynamic models, correlating these with experimental results, to build a foundation for studying elastin mechanics, assembly, and disease. Third, we characterize the temperature response spectrum of elastin-like peptides to design synthetic polymers with tunable switching. We resolve the effect of peptide
Distribution of Upper Paleozoic Coal Seams in the Southeastern Ordos Basin

The Ordos Basin contains abundant coal resources in the Upper Paleozoic strata. They are shallowly buried or exposed in the periphery of the basin, forming recoverable coal mines and coalbed methane resources. For the deeply buried coal seams of the basin, however, due to complex changes and difficult mining, less attention was paid before. In recent years, with the exploitation of tight gas related to coal source rocks, a large amount of drilling and seismic data has been accumulated in the southeastern Ordos Basin, which makes it possible to study the distribution change and factors controlling Upper Paleozoic coal seams. Delineation of deep coal development and distribution is an important basis for coal, coalbed methane and related tight gas resources in the Upper Paleozoic. We use core, logging and seismic data to analyze the coal geophysics, thickness variation, paleotopography and sedimentary facies in the southeastern Ordos Basin. The lower part of the Shanxi Formation (Fm.) and the upper part of the Taiyuan Fm. in the southeastern part of the basin are characterized by low natural gamma ray, low density, high resistivity and high sonic logging values. As the coal velocity is very low and alternates with the high-velocity Taiyuan Fm. and Ordovician limestones, the two sets of coals below and above the Taiyuan limestones form an extremely strong-amplitude reflection in the seismic profile. The two sets of coals are cumulatively 1–10 m thick, averaging 2.4 m, and 4 m is the maximum induvial thickness. The individual coal seams thicker than 2 m cover an area of approximately 2500 km2, and the burial depths of the coal seam range from 2500 to 3000 m. The thick coal seams of the Taiyuan Fm. are mainly distributed proximally in the Ordovician paleokarst depression, while the Ordovician paleokarst depression without incised origin was deposited by distal coeval limestone rocks. There is a complementary relationship between the coal seams and the thickened zone of distributary channel sandstone in the Shanxi Fm.
