Relationship between Ball Impact Point, Type of Stroke and Shot Direction in High-Performance Padel

This study aimed to analyze the relationship between ball impact point, type of stroke, and shot direction in high-performance padel. A total of 8363 strokes from nine matches of three national tournaments involving a total of 24 male players were subjected to systematic observation. The variables analyzed were type of stroke, shot direction, and ball impact. A descriptive analysis was conducted for each study variable, with a comparison of the variables performed using Pearson’s Chi-Square test, column proportions determined using a Z test according to Bonferroni (p < 0.05), an association established by corrected standardized residuals, and an effect size calculated using Crammer’s V. The results showed that the most-used stroke types were volleys, serves, groundstrokes, and backwall shots (67.6%). The cross-court direction stood out over down-the-line and inside-out directions. Finally, almost two-thirds of the impact point locations were forward. In addition, the type of stroke determined shot direction and ball impact location. Moreover, the ball’s impact location significantly determined shot direction. In conclusion, these results suggest that the ball impact location and the type of stroke provide information from which padel shot direction can be anticipated. Such knowledge may constitute a very important factor affecting performance and success among padel players.

University students’ recognition of typical wave optics patterns

The recognition and distinction of typical interference and diffraction patterns are among the expected learning outcomes of studying wave optics. Previous studies have reported high school students’ difficulties with this task. In this study, we investigated university students’ ability to distinguish typical wave optics patterns obtained by the double slit, single slit, and diffraction grating. We also used eye tracking to obtain an insight into the distribution of students’ visual attention during the task. The results showed that university students had similar difficulties in recognizing wave optics patterns as high school students. They mostly struggled with identification of the double-slit interference patterns and diffraction grating patterns of monochromatic light while they were more successful in recognition of the diffraction pattern of white light on an optical grating and single-slit diffraction patterns. The eye-tracking data also revealed that students spent more time attending colourful than grey patterns in questions regarding diffraction of white light on an optical grating, thus suggesting that they were aware that the diffraction grating separates white light into colours. In questions regarding monochromatic light patterns, students overall mostly attended the single-slit diffraction pattern probably because of its distinct central maximum. Furthermore, the longer fixation duration for patterns compared to the text implies that students found it easier to extract information from the text than from the patterns. No prior research has compared the number of transitions during problem solving with the accuracy of the answers. In this study, we observed that students who incorrectly solved a task demonstrated a significantly higher number of gaze transitions between the question and the options, as well as among different options. The results of this study indicate that the recognition of typical wave optics patterns is also difficult for university students, thus suggesting that more attention should be paid to systematic observation and identification of key features of basic wave optics phenomena in lecture demonstrations and student laboratories.

The Effect of Physical Education Content on Children’s Activity During Recess

ABSTRACT Background Physical activity plays a crucial role for primary and secondary prevention of various chronic diseases that can lead to premature morbidity and mortality. Purpose This study was designed to investigate (a) elementary boys’ and girls’ voluntary participation in team handball during recess, while it was being simultaneously taught in physical education (the intervention phase) and after the physical education lessons had concluded (maintenance phase); and (b) the moderate-to-vigorous physical activity (MVPA) levels during physical education, team handball recess, and traditional recess. Methods One hundred thirty third grade elementary school children (53 girls, 77 boys) from six schools were taught a 10-lesson team handball unit during physical education. Ten team handball recess sessions (20 min) were organized during lunch recess in which children could voluntarily participate. Systematic observation was used to assess children’s MVPA in all settings. Results There were no significant differences between boys (49%) and girls (55%) for participation in team handball recess during intervention and maintenance phases. Boys achieved more MVPA in physical education (33% vs 29%, p < .001), team handball recess (52% versus 47%, p < .05) and traditional recess (51% versus 40%, p < .05) compared to girls. Translation to Health Education Practice Connecting recess to physical education creates an opportunity where children can voluntarily engage in activities they have learned, while enabling them to generate higher MVPA levels compared to traditional recess, especially for girls.

Distinguishing Intuitive and Deliberative Reasoning Regarding Different Aspects of Science Classroom Discourse

Purpose The current study aimed to identify the distances between a science teacher's intuitive reasoning and researchers’ systematic analysis of various aspects of science classroom discourse. An expert science teacher, given the pseudonym Jake, engaged in self-reflective processes regarding different aspects of classroom discussions to assess the variations and similarities between the teacher's intuitive estimations and the researchers’ data-based reasoning. Design/Approach/Methods Data collection involved in-depth interviews and video recording. Six aspects of science classroom discourse were considered to elucidate the distances: structure, interactional pattern, verbal sequence, typology, cognitive demand, and communicative approaches. Findings The quantitative distances between Jake's estimations and systematic observations of the six aspects of science classroom discourse varied across different aspects of the observed science lesson. While no consistent pattern was observed in the distances, there were increasing and decreasing gaps between the different aspects of science classroom discourse. Originality/Value Considering the contemporary arguments on human cognition and the professional development of science teachers, potential reasons for the differences were explored. Educational recommendations were provided, particularly regarding supporting science teachers’ journey toward becoming reflective inquirers or researcher-teachers.

MRO overview: Sixteen years in Mars orbit

Launched on August 12, 2005, the Mars Reconnaissance Orbiter (MRO) entered Mars orbit on March 10, 2006. Following a period of aerobraking, MRO completed its entry into its primary science orbit in September 2006, initiating a program of systematic observations of Mars that still continues. Five providers, including the Italian Space Agency, provided 6 instruments for flight, observing the surface, atmosphere, and subsurface of Mars with greater spatial resolution and systematic coverage than ever before. Two investigations utilized the spacecraft accelerometers and tracking of the orbiter via the Deep Space Network to study upper atmosphere densities and the gravity field of the planet. The data acquired by MRO have revealed a dynamic planet whose change from an ancient wetter climate to the drier climate of today was a complex transition and not a simple “drying out”. Furthermore, that climate continues to change even today. The diversity of the early habitable environments, the ice ages recorded in the polar cap layering and subsurface ice deposits, the repeating patterns of dust storms, and the revelation of new features at the limit of resolution are all part of the scientific return from MRO during nearly a decade of Mars years. The story of that mission, of the evolution of its capabilities, and its contributions to our current understanding of Mars are the subject of nearly two dozen papers in the Icarus special issue, MRO: Sixteen Years at Mars. Three papers describe in more detail the evolution of instrument operations and data products over the mission; several papers describe new analysis techniques for the radar, including construction of 3-dimensional views, and for the atmospheric sounder, enabling better retrievals in a dusty lower atmosphere. Other papers report on recent research including, but not limited to, dune movement, the roles of water and carbon dioxide ice in surface change, and attempts to understand the formation and fading of the enigmatic recurring slope lineae. This paper describes general aspects of the MRO spacecraft, payload, and mission as context for the special issue papers; it also summarizes scientific results and mission support events on a mission phase by mission phase basis to give a time history of discovery and effort.

A Machine-Learning-Assisted Classification Algorithm for the Detection of Archaeological Proxies (Cropmarks) Based on Reflectance Signatures

The detection of subsurface archaeological remains using a range of remote sensing methods poses several challenges. Recent studies regarding the detection of archaeological proxies like those of cropmarks highlight the complexity of the phenomenon. In this work, we present three different methods, and associated indices, for identifying stressed reflectance signatures indicating buried archaeological remains, based on a dataset of measured ground spectroradiometric reflectance. Several spectral profiles between the visible and near-infrared parts of the spectrum were taken in a controlled environment in Cyprus during 2011–2012 and are re-used in this study. The first two (spectral) methods are based on a suitable analysis of the spectral signatures in (1) the visible part of the spectrum, in particular in the neighborhood of 570 nm, and (2) the red edge part of the spectrum, in the neighborhood of 730 nm. Machine learning (decision trees) allows for the deduction of suitable wavelengths to focus on in order to formulate the proposed indices and the associated classification criteria (decision boundaries) that can enhance the detection probability of stressed vegetation. Noise in the signal is taken into account by simulating reflectance signatures perturbed by white noise. Applying decision tree classification on the ensemble of simulations and basic statistical analysis, we refine the formulation of the indices and criteria for the noisy signatures. The success rate of the proposed methods is over 90%. The third method rests on the estimation of vegetation/canopy reflectance parameters through inversion of the physical-based PROSAIL reflectance model and the associated classification through machine learning methods. The obtained results provide further insights into the formation of stress vegetation that occurred due to the presence of shallow buried archaeological remains, which are well aligned with physical-based models and existing empirical knowledge. To the best of the authors’ knowledge, this is the first study demonstrating the usefulness of radiative transfer models such as PROSAIL for understanding the formation of cropmarks. Similar studies can support future research directions towards the development of regional remote sensing methods and algorithms if systematic observations are adequately dispersed in space and time.

Contribution of VLF electromagnetic survey to the investigation of Hessdalen lights (Norway)

Hessdalen valley in Norway is known for luminous phenomena suddenly and evenly appearing temporarily. Since several decades, these phenomena are observed by many witnesses, and they are sometimes traced by geophysical devices. The first appearance in modern times was reported in 1981 but systematic observations started during winter of 1984 when the Hessdalen project was launched. Later, Østfold University College led the project and yearly organized one to two field campaigns, with the objective to systematically record and investigate the phenomenon. Till that epoch, detailed tectonics, fault systems and superficial conductive structures remained unknown. Therefore, during the last years, VLF surveys have been performed in Hessdalen valley as part of six geophysical field campaigns which sometimes also included Total Magnetic Field and Self Potential spatial ground measurements. VLF measurements have been carried out on a 20 m average spacing along many traces totaling to100 km length. The entire covered area was about 100 km2.In this paper, we focus on the results of the VLF measurements. Several conductive zones have been found. They are mainly related to mineral deposits (mainly sulfides). The trace at the ground surface of these conductive zones could suggest that they draw an ellipse of 6 by12 km, related to the shape of the gabbro intrusion present in the area and oriented in the SW-NE direction. The results combined with other geophysical data contribute to better understand how the near surface structures (depth less than a few hundred meters) could supply the generation of the so-called Hessdalen lights (‘HL’) and explain why these lights appear inside this valley. The particular geological structure detected in Hessdalen valley may encourage similar campaigns in other areas where similar phenomena are observed.

Feasibility of meteor surveying from a Venus orbiter

Meteor and bolide phenomena caused by the atmospheric ablation of incoming meteoroids are predicted to occur at the planet Venus. Their systematic observation would allow to measure and compare the sub-mm to m meteoroid flux at different locations in the solar system. Using a physical model of atmospheric ablation, we demonstrate that Venus meteors would be brighter, shorter-lived, and appear higher in the atmosphere than Earth meteors. To investigate the feasibility of meteor detection at Venus from an orbiter, we apply the SWARMS survey simulator tool to sets of plausible meteoroid population parameters, atmospheric models and instrument designs suited to the task, such as the Mini-EUSO camera operational on the ISS since 2019. We find that such instrumentation would detect meteors at Venus with a 1.5× to 2.5× higher rate than at Earth. The estimated Venus–Earth detection ratio remains insensitive to variations in the chosen observation orbit and detector characteristics, implying that a meteor survey from Venus orbit is feasible, though contingent on the availability of suitable algorithms and methods for efficient on-board processing and downlinking of the meteor data to Earth. We further show that a hypothetical camera onboard the upcoming EnVision mission to Venus similar to the ISS instrument should detect many times more meteors than needed for an initial characterisation of the large meteoroid population at 0.7 au from the Sun.

Enhancing academic performance and student engagement in health education: insights from Work Station Learning Activities (WSLA)

Making health science students aware of the importance of basic science knowledge for professional practice is a major educational challenge, especially during the early years of preclinical courses. Here, using an integrated curricular approach, we analyze whether Work Station Learning Activities (WSLA), which combine active learning methodologies for teaching basic science in clinical scenarios, can help to develop deeper learning and student engagement. In order to increase student motivation, we evaluated the effectiveness of WSLA using statistical analyses and an observation tool based on the ICAP (Interactive, Constructive, Active, and Passive) framework, which categorizes learning tasks based on the nature of student engagement. Statistical analyses revealed positive correlations between the different summative evaluations along the development of the activities, indicating the learning process inherent to WSLA progression and affirming the positive influence of WSLA on academic outcomes. Comparing the pre- and post-tests, students scored significantly higher on the post-test (statistically significant p < 0.001). WSLA promotes both constructivist and interactive learning, as validated by its alignment with the ICAP model. The study examines student engagement through systematic observation, revealing a relationship between student engagement and final grades. Students who exhibit constructive learning consistently earn higher grades, emphasizing the positive impact of active engagement. Thus, passive behavior profiles show a significant proportion of fails (40%), while constructive profiles stand out as the sole recipients of the coveted excellent rating. Ultimately, this study contributes to our understanding of the effectiveness of WSLA in promoting active learning and enhancing student engagement within integrated health education curricula. It highlights the importance of active learning behaviors for academic success and suggests avenues for further research to optimize integrated teaching methodologies in medical education.

Optimizing restoration duration to maximize CO2 uptake on the Tibetan Plateau

Grasslands cover one-third of the terrestrial area, though half of them have been degraded and primarily due to overgrazing. The Tibetan Plateau (TP) is home to the largest area of alpine grassland on Earth, experiencing a typical degradation-restoration story over the past three decades. With the large-scale implementation and long-term duration of ecological projects aimed at restoring degraded grasslands by fencing across the TP, there is considerable uncertainty regarding the direction and magnitude of changes in the carbon (C) sink function. To address this, we combined ten pairs of systematic field observations at the site scale with literature compilation, aiming to clarify whether restoration still contributes to C uptake and its driving factors. Our results show that after a decade of restoration, living biomass was enhanced by over 80 %, and litter accumulation increased by 3.68 ± 1.25 times across all ecosystem types, although these changes were barely reflected in soil C. Litter caused consistent negative impacts on CO2 uptake across all vegetation types, despite restoration having increased CO2 uptake by half in alpine steppes and alpine meadows. This negative impact was more evident in alpine wetlands, where the quantity of litter was double the living biomass. The thick layer of litter produced a shading effect that further limited the photosynthetic yield of living plants, regulating the restoration-induced CO2 gain or loss. Combining 246 cases across the TP further highlights the need to shorten the duration of restoration to maximize CO2 uptake while also benefitting sustainability, which is deserving of attention from both the scientific community and policy-makers.

IMPACT OF CLASSROOM OBSERVATION TOOL AND RESULTS-BASED PERFORMANCE MANAGEMENT SYSTEM ON ELEMENTARY SCHOOL TEACHER PERFORMANCE

This literature review explores the implications of utilizing the Classroom Observation Tool (COT) and Results-Based Performance Management System (RPMS) on teaching performance among educators in public elementary schools. The COT serves as a structured instrument for assessing classroom activities, while the RPMS provides a framework for evaluating teacher performance based on professional standards. Through a comprehensive analysis of existing research and policy documents, this review examines the impact of these systems on teaching effectiveness and student outcomes. Research indicates that the systematic use of the COT allows educators to identify areas of strength and growth in their teaching practice, leading to targeted professional development interventions. Additionally, the integration of the RPMS ensures alignment between teacher assessments and professional standards, promoting accountability and continuous improvement in teaching practice. Studies have shown that educators who participate in regular classroom observations and performance evaluations experience enhanced job satisfaction and morale, leading to greater retention and commitment to their profession. Moreover, the implementation of these systems has been associated with improvements in student learning outcomes, as teachers are better equipped to meet the diverse needs of their students. However, challenges such as resource constraints and resistance to change may hinder the effective implementation of these systems. Moving forward, further research is needed to explore the long-term impact of the COT and RPMS on teaching performance and student achievement. Overall, this literature review highlights the importance of incorporating systematic observation and performance evaluation mechanisms into teacher professional development initiatives to promote continuous improvement in teaching practice and enhance student learning outcomes in public elementary schools.

Microbial landscape of periodontal pockets against local antibacterial therapy of chronic generalized periodontitis: a multicenter clinical trial

Background. A microbial nature of periodontitis requires an accurate analysis of the pathogenic potential of the periodontal pocket microflora thereby enabling correct diagnosis to be made and the most effective pharmacological agent to be selected for treating chronic periodontitis. Metronidazole demonstrates excellent results for anaerobic microorganisms in the periodontal pocket, whereas minocycline hydrochloride, moxifloxacin and amoxicillin/clavulanate are efficient for aerobic microorganisms. However, specialists find considerably relevant to analyze the correlations between specific bacterial associations in the periodontal pocket against local antibacterial therapy, as well as to track the contents of periodontal pockets long after antibacterial therapy. Therefore, a microbiological analysis of periodontal pocket contents is considered necessary in order to select and monitor the effectiveness of local antibacterial therapy.Objective. To evaluate the effectiveness of local antibacterial therapy for chronic generalized periodontitis by means of analysis of changes in the microbiological composition of periodontal pockets.Methods. The clinical trial involved 144 patients with chronic generalized periodontitis. The study included examination of patients and analysis of clinical data bases of the Department for General Practice Dentistry, Kuban State Medical University and the Dentistry Department, Stavropol State Medical University of the Ministry of Health of the Russian Federation. The trial included patients aged 30 to 60 with a diagnosis of chronic generalized periodontitis of different severity. All periodontitis patients were divided into 2 groups depending on the therapy: main and control groups. Each group had three subgroups depending on the severity of the pathologic process. The first subgroup of the control group (chronic generalized periodontitis of mild degree) consisted of 16 people (11.1%), the second subgroup (chronic generalized periodontitis of moderate degree) — 31 people (21.5%), the third subgroup (chronic generalized periodontitis of severe degree) — 7 people (4.9%). The first, second and third subgroups of the main group consisted of 28 (19.4%), 48 (33.3%) and 14 persons (9.7%) respectively. The severity of periodontitis was determined by the depth of the periodontal pocket, degree of bone resorption (according to x-ray examination), and pathologic tooth mobility. A local anti-inflammatory therapy for the patients of the control group included oral baths with propolis (15–20 drops of 10% propolis tincture diluted in 100 ml of warm water) 3 times a day for 7 days starting from the first visit. At the final stage of treatment after preliminary scaling and rootplaning, patients of the control group received antiseptic gel with 10% metronidazole and 2% chlorhexidine bigluconate to be injected into periodontal pockets with over 4 mm depth. Additionally, applications of adhesive dental films Diplene Denta L (with lincomycin) and Diplene Denta M (with metronidazole) were prescribed to be done in the home. In addition to the above-mentioned comprehensive therapy, patients of the main group received a single insufflation of minocycline hydrochloride microspheres into each periodontal pocket. The tools for the patients of the main group included plastic cannulas with minocycline hydrochloride microspheres in the form of powder in the tip of the cartridge, and a special syringe-insufflator. The technique of antibiotic insufflation into the periodontal pocket was preliminary trained on the model of jaws with the studied pathology. Statistical analysis of the results was performed using variance analysis in the Excel Microsoft Office 2016 (Microsoft, USA).Results. According to the systematic observation of the patients from the control group, periodic fluctuations in microbial population in the majority of pathologic pockets obtained a specific regularity: a decrease in the number of microorganisms on day 21 was followed by its increase in the subsequent period of observation after 30 and especially 60 days. According to the ongoing follow-up of the patients of the main group, fluctuations of microbial population in the majority of pathologic pockets obtained a certain regularity: a significant reduction in the number of microorganisms on day 21 was followed by its slight rise in the subsequent period of observation after 30 and a slight increase again in 60 days. Fluctuations in the number of microorganisms of periodontal pockets in the main group reveal their specific character: their number remained invariably lower than that of the control group throughout the observation period, while the total number of detected periodontopathogens decreased.Conclusion. The established correlations between the main indicators of microbiological status of periodontal pockets and the severity of chronic generalized periodontitis within different periods after the local therapy confirm the positive dynamics of treatment in the main group, where patients were insufflated with minocycline hydrochloride microspheres, proved by a change in the typology of microbial status of periodontal pockets and a number of periodontopathogenic microorganisms.

Unveiling the Impact of Language Input and Regular Exposure to Language in Turkish (Second Language) and English (Foreign Language) Education Through a Dynamic Usage-Based Approach

The focus of the study is on the commonly problematic speaking skills of second/foreign language learners during interaction and communication. The participants are able to communicate effectively to some extent; however, they struggle with speaking fluency and accuracy. Consequently, the potential purpose is to investigate the efficacy of the Dynamic Usage-Based Approach (DUB) in developing second/foreign language learners' speaking skills. Under investigation were 120 second/foreign language learners between the ages of 18 and 22. Using a quantitative quasi-experimental study design, the study was conducted in four intact B1 level second language (Turkish) and foreign language (English) classes. The research lasted four weeks and included a total of 12 classes. The DUB was used in the study, as well as the "Movie method," which involves systematic observation and analysis of films to increase language exposure and foster practical language use in real-world circumstances. The study included a a pre-test, treatment, post-test, and questionnaire. The participants were divided into experimental and control groups through random assignment. The Independent Sample T-Test was used to examine the results, as well as a descriptive analysis of the questionnaire data. The results indicate that the DUB has proven its efficacy in experimental groups and could potentially be used to help students enhance their speaking skills. It was observed that the control groups, who received the usual instructions from their instructors, attained comparable post-test scores. While the development of the experimental classes differed significantly, the results indicate that DUB is more beneficial for acquiring overall oral skills. The questionnaire also included a measure of confidence. Students in the experimental classes were more likely to use L2 than those in control groups, according to the data.

Differences between a teacher educator’s and prospective classroom teacher’s talk-based strategies for fostering academically productive classroom talk

ABSTRACT The current study presents complex comparative classroom discourse analyses for understanding teacher educators’ and candidate teachers’ talk-based strategies for potentially fostering academically productive classroom talk. Two participants’ in-class teaching videos regarding talk move and interactional pattern typologies, as well as communicative approach orientations, were analysed. A multifaceted, comparative analysis was conducted to portray how and to what extent teacher educators and their students as candidate teachers enact different in-class practices surrounded by talk-based strategies in promoting intellectual activity. A systematic observation approach followed, including theory-laden and data-driven coding and quantifying the three interrelated aspects of the classroom talk for presumably promoting intellectual productivity. The educator used the talk moves more effectively than the candidate teacher to create an argumentative classroom setting, encouraging the students to comment on and enrich each other’s claims, encouraging the students to present reasonable arguments, and engaging the students in the metacognitive activity. The educator was also able to sustain more open-ended chains of interactions in addition to the interactive-dialogical communicative approach orientation compared to the candidate teacher. The qualitative and quantitative differences are discussed, and educational implications are presented, especially in teacher noticing.
