Prediction of Heteroscedastic Sports Data By using Regression and Various Machine Learning Models
Authors: Muhammad Waqas  
Published: September 2024

This study investigates the impact of extra deliveries—wide’s, no balls, byes, and leg byes—on T20I cricket match outcomes. It aims to find out whether these extras have a significant effect on the result and which type contributes the most runs. Using heteroscedastic data from the previous three T20I World Cups (20212024), the analysis underlines the importance of reducing extras to boost a team's chances of winning. OLS assumes that the error component has constant variance; when this assumption is violated, heteroscedasticity arises, resulting in incorrect predictions and conclusions. This study employs several types of machine learning techniques to increase prediction accuracy for heteroscedastic data. We applied machine learning models such as Decision Tree, Random Forest, Gradient Boosting, and K Nearest Neighbor, as well as Linear Regression, to predict values in test datasets. Machine learning models typically outperformed linear regression, resulting in decreased sum of squares errors, with some models producing predictions that were very close to observed values. This study shows that machine learning works well with heteroscedastic data.

No phylogenetic evidence for angiosperm mass extinction at the Cretaceous–Palaeogene (K-Pg) boundary
Authors: Thompson Jamie , Venditti Chris 
Published: September 2024

The Cretaceous–Palaeogene mass extinction event (K-Pg) witnessed upwards of 75% of animal species going extinct, most notably among these are the non-avian dinosaurs. A major question in macroevolution is whether this extinction event influenced the rise of flowering plants (angiosperms). The fossil record suggests that the K-Pg event had a strong regional impact on angiosperms with up to 75% species extinctions, but only had a minor impact on the extinction rates of major lineages (families and orders). Phylogenetic evidence for angiosperm extinction dynamics through time remains unexplored. By analysing two angiosperm mega-phylogenies containing approximately 32 000–73 000 extant species, here we show relatively constant extinction rates throughout geological time and no evidence for a mass extinction at the K-Pg boundary. Despite high species-level extinction observed in the fossil record, our results support the macroevolutionary resilience of angiosperms to the K-Pg mass extinction event via survival of higher lineages.Image credit: [Rhus nigricans (fossil leaf) (Green River Formation, Eocene; Utah, USA).

Écouter L’Amante anglaise dans la version de la création
Authors: Mervant-Roux Marie-Madeleine 
Published: September 2024

Jusqu’à ces dernières années, sauf rares exceptions, les spécialistes d’études théâtrales ou de littérature dramatique négligeaient les archives sonores, même lorsqu’ils travaillaient sur un théâtre « de voix » ou « d’écoute ». Dans le cas de L’Amante anglaise, l’enregistrement audio de la création par Claude Régy (en décembre 1968, dans la salle Gémier du TNP au Palais de Chaillot), dont Michael Lonsdale assurait qu’il avait été réalisé, n’a été retrouvé qu’en 2010 (il existe en réalité deux enregistrements, datant du 22 février et du 21 décembre 1969). Malgré la difficulté générale à entendre pertinemment le passé et, dans le cas d’une œuvre aussi commentée, à résister à l’histoire « officielle » qui façonne nos attentes sur ce que nous avons à écouter, en l’occurrence le récit d’une inspiration mutuelle, devenue presque légendaire, entre l’auteur et le metteur en scène, l’audition de ces captations a révélé l’intervention d’un autre sujet poétique, pluriel et décisif. L’écoute méthodique de trois extraits permettra au lecteur de l’entendre à son tour.
Dominique Blanc sous le regard de Patrice Chéreau
Authors: Deregnoncourt Marine 
Published: September 2024

Publié en 1985, La Douleur a été, en 2008, porté à la scène par la comédienne française Dominique Blanc, sous le regard du metteur en scène Patrice Chéreau et du chorégraphe Thierry Thieû-Niang. Quatorze ans plus tard, cette actrice reprend ce spectacle épuré comme un seul-en-scène, avec la complicité du chorégraphe, en hommage à la mémoire et au travail de Chéreau, disparu en 2013. Comment est né ce projet lié à un théâtre destiné à être « lu » et non pas « joué » et quels sont les défis posés par un tel type de théâtre ? Au-delà de l’hommage à Patrice Chéreau, pourquoi reprendre cette création en 2022 ? Tels sont les trois temps forts de notre article.

“It’s almost the 14th of February [Valentine’s Day] so I thought of you”: The Role of Positionality in Navigating Field Relations during a Police Ethnography

“It’s almost the 14th of February [Valentine’s Day] so I thought of you”: The Role of Positionality in Navigating Field Relations during a Police Ethnography
Positionality, along with reflexivity, is a key component of ethnographic research. Traditional male-oriented police ethnographic accounts, however, rarely include a reflection on how researchers’ positionality shaped the research process. While a growing number of female police scholars reflect on gendered power dynamics and strategies for managing trust or flirtatious behaviour, the literature is inconclusive regarding the tension between maintaining field relations characterized by trust while also maintaining a measure of invisibility. In this article, I examine how my positionality impacted the course of fieldwork during a long-term ethnography of the Dutch police. I discuss how my gender and former social work profession, in particular, challenged and provided a resolution through field relations while establishing (in)formal access and gathering data on violent interactions. Moreover, I reflect on the usefulness of Shakespeare’s concept of “confessions of ignorance” and Reyes’ “ethnographic toolkit” as strategies to navigate discomfort and build rapport. The article contributes to the field of policing studies by exploring how we can transform our inevitable differences from liabilities to valuable research assets, enhancing our understanding of the complexities involved in conducting ethnographic police research.

Authors: Tarasevich I. V. , Ereshchenko Yu. A. 
Published: September 2024

Relevance. The main problem lies in the fact that there is a need to raise the results of the national team and further improve athletics in the country, but the resolution of this issue is not possible without increasing the productivity of training young athletes, which should be based on improving the system of sports training.The purpose of the research presented in the article was to study the theory of methodological aspects of the development of speed and strength abilities in athletes at the initial stage.Organization and methods of research. When considering the basic properties of speed and strength abilities, one of the main places is occupied by strength. Among the many forms of development of speed and strength qualities, jumping exercises are considered the most effective.The results of the study and their discussion. Based on the scientific literature, we found out that the speed and strength qualities of athletes at the initial stage need to be developed during the maturation period and developed in conditions of high intensity of exercise. The main and more effective method for the development of speed and strength qualities is the shock method, while special physical exercises of local and global impact on muscle work are used.Conclusions. The management of the training process involves the study of various aspects of the athlete's special preparedness in order to organize training at subsequent stages in accordance with the individual characteristics of those involved. The theory and practice of athletics is multifaceted and is in constant development.
Physiological mechanisms and patterns of improvement of individual body systems under the influence of directed physical training
Authors: Pavlov V. A. , Doronin A. I. 
Published: September 2024

Relevance. Pathologies of the osteoarticular apparatus are quite difficult to respond to drug therapy in combination with gymnastic exercises. To facilitate the course of the disease, various types of physiotherapy techniques are prescribed to the patient. These measures are considered effective, but the negative side of them is the need to visit a medical institution.However, there is an alternative way to use physiotherapy – the use of special medical devices and devices for the treatment of joint pathology. Denas is considered one of the most popular.The purpose of the work is to determine the possibilities of improving the effectiveness of restorative measures using DENAS.Methods and organization of research. The Denas therapy device is based on the use of the method of electroneurostimulation in dynamics for therapeutic purposes. This device is used in order to implement a modern and promising method of traditional treatment – reflexology.The results of the study. In reflexology, CHANCE has become popular due to its good analgesic effect during surgical interventions. Unlike the De-us, previously known devices lost their effectiveness due to the ability of the receptor endings of nerves to get used to electrical stimulation.Conclusions. Today, DENAS therapy allows to achieve the following results: improvement of blood circulation, lymph circulation; regulation of the cardiovascular system and blood pressure; anti-inflammatory, antiallergic and decongestant effect; stabilization of hormonal background; elimination of endocrine disorders; normalization of weight, nervous system functions, sleep; normal functioning of the digestive and genitourinary systems; regulation of metabolism; prevention of stress and depression; increasing the body's potential.
Scientific and methodological foundations for the development of motivation of high school hockey players
Authors: Sazonova S. L. , Surina-Marysheva E. F. 
Published: September 2024

Relevance. The main task is to analyze psychological and pedagogical approaches to the formation of motivation in game sports (using the example of hockey). The paper considers the problem of motivation development in high school hockey players, examines the structure of motivation and its features, identifies the main components of motivation, and defines terminology. The paper identifies the features of high school age, which play an important role in the formation of professional self-determination.The aim of the work was to study the scientific and methodological foundations for the development of motivation of hockey players of old school age.Organization and methods of research. An important structure in the formation of motivation is the emotional sphere of a person. The peculiarity of this structure consists in its variability of functions depending on the object under consideration, as well as in the heterogeneity of the cause of affect. I think the fact that our emotions are physiologically conditioned is well-established. However, the stimulus that triggers emotional reactions may have different origins.The results of the study and their discussion. The implementation of the first mechanism is based on the creation of conditions in which an athlete independently comes to the formation of motives and goals, from which motivation is subsequently formed, as well as which help to maintain effective sports motivation. To implement such a scheme, using the example of a hockey team, it is possible to organize team activity outside the training program that would bring them together, various options are possible here, for example, joint camping.Conclusions. Various aspects of sports motivation, ways to maintain its optimal state, the formation of new motives using multidirectional methods, as well as the formation of motivation through the satisfaction of multi-level needs are considered.
The development of spatial orientation in children 5-6 years old with visual impairment
Authors: Repina A. I. , Trefilova D. A. 
Published: September 2024

Relevance. At the present stage, despite a significant amount of research and various methodological developments, the problem of the development of spatial orientation in children aged 5-6 years with visual impairment remains relevant. The age period of pre-school and junior schoolchildren is called the "golden age", referring to the rate of development of coordination abilities. To develop coordination abilities, we recommend using: multicolored cubes, gymnastic sticks, ropes, balls of different colors and sizes: small, medium (including "sound balls") and large balls. When conducting classes, we recommend using methodological techniques based on motor activity.The aim is to determine the mechanisms of spatial orientation development in children with visual impairments.Organization and methods of research. Visual impairment has a negative effect on the overall physical development of children and their health. In children with visual pathology, there is a significant lag in physical development, and the ability to assess and regulate spatiotemporal and dynamic parameters is significantly reduced.The results of the study and their discussion. The main factor in the development of orientation in the classroom is the gradual dynamic introduction of more complex exercises into classes.Conclusions. When conducting classes, it is necessary to focus on the assessment of indicators of such parameters as speed of motor reaction, orientation in space, dexterity, which are most significant in the development of orientation in space.

Authors: Song Yu , Wang Yu-Yu , Yu Jin-Ling , Yuan Rui , Li Fang 
Published: September 2024

Four novel species of subgenus Russula crown clade collected from northwestern China are described based on morphological and phylogenetic evidence. Morphologically, R. griseorosea Y.Song sp. nov. (subsection Puellarinae) is characterized by its brown pileus with a grayish pink tint, basidiospores with warts often connected by fine lines, orthochromatic pileipellis with long terminal cells and septate pileocystidia; R. micangshanensis Y.Song sp. nov. (subsection Olivaceinae) is diagnosed by its large basidia, hymenial cystidia and basidiospores, and spore ornamentations with unequal crests and often twinned warts, which give the spore distinctive appearance; R. minirosea Y.Song sp. nov. (subsection Laricinae) has very small basidiocarp with pileus less than 3.3 cm in diameter, basidiospores with fine reticulum, small basidia, and septate pileocystidia; R. purpureomarginalis F.Li & Y.Song sp. nov. (subsection Xerampelinae) has large basidiospores with often isolated ornamentations, slim basidia and often septate flexuous pileocystidia. Differences between the four novel species and their closely related taxa were analyzed. Phylogenetic analyses based on both ITS and multi-locus (LSU, rpb2 and tef1) were carried out to confirm the distinct taxonomic status of the four novel species.
THE EMERGENCE OF DAY OF THE WEEK EFFECT IN THE INDIAN NIFTY ENERGY SECTOR: ANALYSIS AND INTERPRETATIONS
Authors: Sanganeria Drishti , Maheswari Raghav 
Published: September 2024

This study delves into the presence and evolution of the day-of-the-week effect within the Indian NIFTY Energy Sectoral Index. Employing a comprehensive dataset of daily returns spanning the years 2005 to 2023, the analysis is segmented into two distinct time periods: 2005-2015 and 2016-2023. This segmentation allows for a granular examination of potential shifts in the nature or intensity of calendar anomalies within this market segment.
Findings from the initial period (2005-2015) reveal the absence of statistically significant day of-the-week effects. This aligns with certain strands of existing research that suggest calendar anomalies might be less prevalent in specific market segments or may experience periods of dormancy. However, the second time period (2016-2023) presents a compelling departure from this pattern, highlighting the dynamic landscape of financial markets. A statistically significant (p-value 0.05) and persistent anomaly arises, with Tuesdays consistently demonstrating the highest average daily returns within the NIFTY Energy Sector. This observation challenges traditional notions of day-of-the-week effects and necessitates a nuanced exploration of its potential drivers.

Published: September 2024

Background
Seed vigor recognized as a quantitative trait is of particular importance for agricultural production. However, limited knowledge is available for understanding genetic basis of wheat seed vigor.

Methods
The aim of this study was to identify quantitative trait loci (QTL) responsible for 10 seed vigor-related traits representing multiple aspects of seed-vigor dynamics during artificial aging with 6 different treatment times (0, 24, 36, 48, 60, and 72 h) under controlled conditions (48 °C, 95% humidity, and dark). The mapping populations were two wheat introgression lines (IL-1 and IL-2) derived from recipient parent (Lumai 14) and donor parent (Shaanhan 8675 or Jing 411).

Results
A total of 26 additive QTLs and 72 pairs of epistatic QTLs were detected for wheat seed-vigor traits. Importantly, chromosomes 1B and 7B contained several co-located QTLs, and chromosome 2A had a QTL-rich region near the marker Xwmc667, indicating that these QTLs may affect wheat seed vigor with pleiotropic effects. Furthermore, several possible consistent QTLs (hot-spot regions) were examined by comparison analysis of QTLs detected in this study and reported previously. Finally, a set of candidate genes for wheat seed vigor were predicted to be involved in transcription regulation, carbohydrate and lipid metabolism.

Conclusion
The present findings lay new insights into the mechanism underlying wheat seed vigor, providing valuable information for wheat genetic improvement especially marker-assisted breeding to increase seed vigor and consequently achieve high grain yield despite of further investigation required.
