El objetivo general es mejorar la obtención de datos faltantes de precipitación pluvial de la cuenta de Ravelo para la captación de agua dulce. Se sistematizaron métodos convencionales y de Inteligencia Artificial (IA) para imputar precipitaciones pluviales. Los métodos convencionales fueron: Servicio Meteorológico Nacional de EE.UU., Razón Normal y Regresión Lineal Simple. En IA, se aplicaron: Regresión Lineal Múltiple, Redes Neuronales Artificiales, Series Temporales, Árbol de Decisión, Perceptrón Multicapa, Bosques Aleatorios y Redes Neuronales Recurrentes, que requieren grandes volúmenes de datos. ELAPAS proporcionó datos de las estaciones de Tumpeka, Ravelo y Cajamarca (2018-2024). Se desarrollaron programas en Python para aplicar métodos convencionales e IA, usando los datos proporcionados para el entrenamiento y pruebas. La comparación de métodos se basó en el error cuadrático medio porcentual. La Regresión Lineal Simple resultó ser el mejor método convencional y el Árbol de Decisión fue el mejor método de IA. Los métodos convencionales dependen de estaciones meteorológicas cercanas, limitando su uso en áreas sin estas estaciones. Los métodos de IA, no requieren esta información y proporcionan estimaciones precisas con pocos años. Este estudio, realizado en la Cuenca de Ravelo, demostró que los modelos de IA son efectivos para estimar la precipitación pluvial.

Published: August 2024

The experiment was conducted in the vegetable field of the Department of Horticulture and Landscape Engineering/College of Agriculture and Forestry University of Mosul during the spring season 2023. The study included three factors. The first factor: Two local cucumber varieties: (gennxt and Mosli). The second factor was compound fertilizer (NPK) at four levels (270, 180, 90.0 kg/ha!) and the third factor: planting dates. Two planting dates were chosen: (4/1/2023) and (4/20/2023). Compound fertilizer (NPK) was added to the soil in three stages, the first three weeks after planting and after the plants reached the appropriate size (four true leaves), and the second and third at an interval of 20 days between one stage and the next. Thus, the experiment included 18 treatments (2 x 2 x 4 = 16). With three replications, the experiment was carried out in the field using a factorial experiment according to a randomized complete block design (RCBD), where the treatments were randomly distributed according to the design used in the experiment. The results were analyzed statistically according to the design used, and the means were compared according to Duncan's multinomial test at the probability level of 0.05.

Figurative language effect on consumer engagement: an empirical investigation for Turkish airline industry
Authors: Koçak Cem Burak , Atalık Özlem
Published: August 2024

Increasing consumer engagement (CE) on social networks is one of marketing problems that brands face in today’s competitive environment. Although prior studies on this concept suggested that content strategies have essential role in improving CE, little is known about figurative language effect. Thus, a novel model and research design to examine how the use of figurative language influence CE behavior on Facebook were proposed. Drawing on Encoding/Decoding Model and brand-consumer communication studies, the 1687 brand posts of Turkish airline Facebook pages with Multiple Linear Regression (MLR) models were analyzed. The findings indicate that several types of figurative languages (idioms, personifications, and similes) are related to the various CE levels (likes, shares, and comments). The findings of this study give tips for understanding the role of figurative language, reshaping engagement level, and redesigning branded content in marketing communication practices on social networks. The experimental model that provides some clues to reconsider online communication strategies across CE based on figurative language is presented.
Leadership and its role in intellectual migration and creativity development
Authors: Oliinyk Olena , Mishchuk Halyna , Bilan Yuriy
Published: August 2024

The study aims to investigate the role of leadership in creativity development, including opportunities arising from the attractiveness of countries for intellectual migrants. Using the authors’ approach for assessing leadership development in the European Union, it is found that the leading positions belong to Finland with an integral index value of 0.85, Denmark (0.83), and the Netherlands (0.76). To test hypotheses about the significant influence of leadership on the attractiveness of countries for intellectual migrants and creativity development, correlation analysis was used. Creativity development was analysed based on the most frequently used indicators of creative economics dynamics. Besides, it was considered that the most obvious result of creative thinking is the innovation development of the countries. The resulting pairwise correlation coefficients for the European Union show a strong relationship between the level of leadership and a country’s ability to attract (0.73) and retain talent (0.80). A positive impact of leadership on creativity development is confirmed by the links with the overall value of the Global Innovation Index (0.79), the growth of innovative companies (0.81), creative outputs (0.58), and cultural employment (0.68). The obtained results prove the need for the development of leadership competencies as an important driver of creativity, talent attraction and generation of innovative solutions.

We present the host galaxies of four apparently nonrepeating fast radio bursts (FRBs), FRB 20181223C, FRB 20190418A, FRB 20191220A, and FRB 20190425A, reported in the first Canadian Hydrogen Intensity Mapping Experiment (CHIME/FRB) catalog. Our selection of these FRBs is based on a planned hypothesis testing framework where we search all CHIME/FRB Catalog-1 events that have low extragalactic dispersion measure (<100 pc cm−3), with high Galactic latitude (∣b∣ > 10°) and saved baseband data. We associate the selected FRBs with galaxies with moderate to high star formation rates located at redshifts between 0.027 and 0.071. We also search for possible multimessenger counterparts, including persistent compact radio and gravitational-wave sources, and find none. Utilizing the four FRB hosts from this study, along with the hosts of 14 published local Universe FRBs (z < 0.1) with robust host association, we conduct an FRB host demographics analysis. We find all 18 local Universe FRB hosts in our sample to be spirals (or late-type galaxies), including the host of FRB 20220509G, which was previously reported to be elliptical. Using this observation, we scrutinize proposed FRB source formation channels and argue that core-collapse supernovae are likely the dominant channel to form FRB sources. Moreover, we infer no significant difference in the host properties of repeating and apparently nonrepeating FRBs in our local Universe FRB host sample. Finally, we find the burst rates of these four apparently nonrepeating FRBs to be consistent with those of the sample of localized repeating FRBs observed by CHIME/FRB. Therefore, we encourage further monitoring of these FRBs with more sensitive radio telescopes.

The contribution of the magnetic field to the formation of high-mass stars is poorly understood. We report the high angular resolution (∼0.″3, 870 au) map of the magnetic field projected on the plane of the sky (B
POS) toward the high-mass star-forming region G333.46−0.16 (G333), obtained with the Atacama Large Millimeter/submillimeter Array at 1.2 mm as part of the Magnetic fields in Massive star-forming Regions survey. The B
POS morphology found in this region is consistent with a canonical “hourglass” with an embedded flattened envelope in a perpendicular direction, which suggests a dynamically important field. This region is fragmented into two protostars that appear to be gravitationally bound in a stable binary system with a separation of ∼1740 au. Interestingly, by analyzing H13CO+ (J = 3–2) line emission, we find no velocity gradient over the extent of the continuum, which is consistent with a strong field. We model the B
POS, obtaining a marginally supercritical mass-to-flux ratio of 1.43, suggesting an initially strongly magnetized environment. Based on the Davis–Chandrasekhar–Fermi method, the magnetic field strength toward G333 is estimated to be 5.7 mG. The absence of strong rotation and outflows toward the central region of G333 suggests strong magnetic braking, consistent with a highly magnetized environment. Our study shows that despite being a strong regulator, the magnetic energy fails to prevent the process of fragmentation, as revealed by the formation of the two protostars in the central region.

Published: August 2024

A comprehensive study of an ungrouped achondrite meteorite, North West Africa (NWA) 11562, was conducted, involving petrology, mineralogy, and mass-independent chromium isotopic composition. NWA 11562 comprises 34.9 vol% olivine, 56.1 vol% pyroxenes, 6.7 vol% Fe–Ni metal and oxides, 2.2 vol% carbon, and 0.2 vol% anhydrite. The oxygen isotopic composition (δ
18O = 6.24‰ ± 0.13‰ and Δ17O = −1.81‰ ± 0.03‰; Meteoritical Bulletin Database) and chromium isotopic compositions (ε
54Cr = −0.82 ± 0.10, 2SE) are consistent with NWA 11562 being a ureilite, and petrographic observations show features similar to those of the common ureilite group meteorites. Olivine (core: Fo99.0 ± 0.1; rim: Fo98.9 ± 0.1) and pyroxene (orthopyroxene: Mg# 99.0 ± 0.2; clinopyroxene: Mg# 99.1 ± 0.7) core compositions are more magnesian than in any previously known ureilite and lack the characteristic reduction rims of ureilites. Rounded small olivine grains within NWA 11562 indicate that the meteorite experienced impact and associated melting. Combined with the characteristic Fe/Mn ratio (3.84 ± 0.16) and Mg# (99.0 ± 0.1) of olivine cores, we suggest that NWA 11562 represents a more Mg-rich ureilite than any previously reported. NWA 11562 has a high 55Mn/52Cr ratio, and when combined with literature data, it plots on a well-defined 53Mn–53Cr isochron, providing a more accurate age, i.e., 4566.7 ± 0.8 Ma, overlapping previous work. This age may represent the result of early partial melting of the ureilite parent body.
Similar drivers but distinct patterns of woody and herbaceous alien plant invasion
Authors: Gregory David , White Matt , Catford Jane
Published: August 2024

The extent of alien plant invasion and numbers of invasive species are increasing, exacerbating invasion impacts. Effective and efficient management requires understanding the drivers and distribution of plant invasions at the landscape scale. In this study, we used a species distribution modelling approach to determine whether the patterns and correlates of alien invasion vary by plant growth form. Focusing on the occupancy and abundance of forbs, graminoids and woody vegetation, we used boosted regression trees (BRTs) to characterise alien plant invasion risk in two major catchment regions in Victoria, Australia. Of 7,630 quadrats surveyed between 1970 and 2019, 69% contained alien plants, with forbs being the most prevalent. Alien plants constituted 22% of the total number of plant species recorded. Alien species cover varied widely, with forbs and graminoids showing higher mean cover compared to woody plants. Abiotic conditions, particularly temperature and precipitation, had the greatest influence on alien plant invasion overall, explaining 41-76% of observed variation. Summer mean maximum temperature was a strong predictor across all growth forms. Forbs and graminoids showed increased occupancy with higher vegetation cover but lower proportional cover, while woody plants had a negative relationship with their own cover type. High levels of invasion were predicted in areas with intensive land use, such as urban and agricultural zones. Forbs had a high probability of occupancy throughout the region, even in higher elevations, while graminoids and woody vegetation were more restricted to lower elevations and areas with human activity. The study highlights that alien plant invasion is influenced by a complex interplay of abiotic factors, propagule pressure, human activity and biotic conditions. The findings underscore that while there are common drivers across growth forms, specific patterns and influences vary. For instance, forbs are more widespread but less dominant in high vegetation areas, while woody plants were less common and more constrained by existing vegetation. Management strategies should prioritize maintaining and restoring native vegetation to limit the dominance of alien species and controlling invasive plants after disturbance. Although single-species models remain valuable, our study shows that species distribution models based on growth form offer a practical approach for assessing plant invasions across diverse landscapes.
Three new species of the genus Clavulina (Hydnaceae, Cantharellales) from North China based on morphological and phylogenetic analysis
Authors: Gao Yue , Tong Xin , Zhou Hao , Wang Hai-Qi , Li Cheng , Hou Cheng-Lin
Published: August 2024

Clavulina possesses important ecological and economic value and has attracted extensive attention from mycologists. Macrofungal diversity is high in China, but Clavulina species have not been thoroughly studied. In this study, based on morphological evidence and phylogenetic analyses of the nucleotide sequences of three loci (nrITS, nrLSU, and rpb2), three new species of Clavulina from North China were identified. Morphologically, Clavulina chengdeensis is characterized by its white to dirty white basidiomata with somewhat pale orange tips and somewhat wrinkled hymenium. Clavulina griseoviolacea is characterized by its gray to dark grayish violet basidiomata, with a sometimes-white stipe base, monopodial or irregularly polychotomous toward branch apices. Clavulina pallida is characterized by its white to pale cream white basidiomata with somewhat orange tips. Phylogenetically, the three new species form three independent branches with high support values in the phylogenetic tree.

Published: August 2024

This article introduces a novel method that integrates collaborative filtering into the naive Bayes model to enhance predicting student academic performance. The combined approach leverages collaborative user behavior analysis and probabilistic modeling, showing promising results in improved prediction precision. Collaborative Filtering explores user behavior patterns, while Naive Bayes employs Bayes' theorem for probabilistic data classification. Focused on predicting academic success, the integration incorporates collaborative patterns from student data for increased accuracy. The method considers similar students' performance and behavior for nuanced, personalized predictions. Starting with diverse data collection, including collaborative patterns among students, Collaborative Filtering identifies relationships and patterns among those with similar academic histories. These insights enrich the naive Bayes algorithm, creating a holistic approach for more accurate predictions, and contributing to ongoing machine learning initiatives in education.

The purpose of this study was to investigate the effect of game-based karate training on learning basic karate skills and karate children's interest in physical activity. The statistical population of this research included all 6 to 8-year-old female karate players in Sowmeh Sara city, Iran and twenty subjects were randomly selected and divided into two experimental and control groups of 10. The experimental group practiced game-based karate training for eight weeks. The training program was designed based on the principles of the Fundamental stage of the Canadian model of long-term development of athletes (LTAD) for karate sport. Physical activity enjoyment scale in children was used to measure children's interest in physical activity and karate yellow belt test was used for measurement of learning basic karate tasks. ANCOVA test was used for data analysis using SPSS 24 software at a significance level of 0.05. The results showed that there was no significant difference in the learning of basic karate skills, but a significant effect was seen in the enjoyment of children in the experimental group for physical activity (sig<0.001). Therefore, game-based karate training can help children learn basic karate skills as much as the traditional method, and also increase their enjoyment in physical activity more effectively

A relação entre a participação esportiva (PE) e a coordenação motora global (CMG) se associa à idade. No entanto, o tempo envolvido na PE pode ser outro mediador. Assim, o objetivo foi investigar a relação entre a CMG e a PE em crianças e adolescentes envolvidos na PE, controlado pelo tempo de prática. Para isso, foram analisados 111 meninos (88 de 6 a 9 anos; 23 de 10 a 12 anos), com PE de duas a quatro modalidades e com o tempo de prática entre um e seis anos. A CMG foi auferida pelo Körperkoordinationstest Für Kinder e a PE mediante entrevista semiestruturada com os responsáveis legais. Os coeficientes de Spearman indicaram que para as crianças dos 6 aos 9 anos de idade não houve correlação entre a CMG e a PE (p >0,05), mesmo quando controlada pelo tempo nas PE. Já para o grupo dos 10 aos 12 anos, houve correlação moderada (ρ = 0,515, p <0,01). Essa informação permite ao profissional de Educação Física entender que a experiência motora das crianças mais jovens é fundamental para potencializar o desenvolvimento motor e que sua implicação na manutenção da participação em atividades esportivas ocorrerá somente nas fases avançadas da infância.

Previous research have established that students who derive enjoyment from engaging in sports can have an advantageous influence on their resilience in academic pursuits. However, while there is a significant amount of research undertaken on this topic internationally, there is a lack of studies specifically focused on the Higher Education context in the Philippines. The study attempted to ascertain the immediate influence of sports enjoyment on academic resilience. Upon collecting data from 229 student-athletes at a particular state university, it was observed that sports enjoyment and academic resilience are positively and significantly related [r(227) = .299, p <.05]. Additionally, it was noted that the enjoyment of sports has a favorable influence on academic resilience [F(1, 227) = 22.228, p <.001]. The findings suggest that engaging in diverse sports events can have an important beneficial effect on academic achievement and reduce difficulties in a demanding academic setting. Future research directions and recommendations are presented in this paper.

Introduction: Traditional games offer a captivating and enjoyable avenue for promoting physical activity in children. This study investigates the potential of integrating such games into physical education curricula to enhance physical fitness and vestibular stabilization—a crucial aspect of balance and coordination—in pre-teen students. Problem Statement: This research addresses the question: Can incorporating traditional games into physical education (PE) programs lead to greater improvements in physical fitness and vestibular stabilization compared to traditional PE activities alone? Approach: This study examines the impact of a PE program enriched with traditional games on the physical fitness and vestibular stabilization of students aged 10-11 years. Materials and Methods: Sixty students (aged 10-11 years) were randomly assigned to either an experimental group (EG) participating in a PE program incorporating traditional games or a control group (CG) following a standard PE curriculum. The study spanned nine months, with both groups undergoing assessments for physical fitness and vestibular stabilization before and after the intervention. Results: While both groups demonstrated improvements in physical fitness and vestibular stabilization following the intervention, the EG exhibited significantly greater enhancements. The CG showed modest improvements (2.15% to 8.56% in fitness and 6.50% in vestibular stabilization), while the EG achieved substantial gains, with fitness improvements ranging from 9.02% to 20.20% and a remarkable 28.98% improvement in vestibular stabilization—a 4.5-fold increase compared to the CG. Discussion: The substantial improvements observed in the EG underscore the effectiveness of incorporating traditional games in enhancing both physical fitness and vestibular stabilization in young students. Conclusions: This study provides compelling evidence that integrating traditional games into PE curricula for students aged 10-11 years can significantly enhance both their physical fitness and vestibular stabilization, surpassing the benefits observed in traditional PE activities.

Published: August 2024

Today's modern aircraft are built with highly integrated avionics solutions that provide pilots enhanced situational awareness and reduced workload. This paper researches how highly integrated avionics can be architected in a way to simplify modification and augmentation of avionics systems with new features developed by third parties (in addition to the original avionics provider). Our objective is to determine the best technical solution(s) to enhancing avionics system architectures to support third party development. We reviewed technical solutions to enable third party integration, including Future Airborne Capability Environment (FACE™), ARINC 661, video input, table driven user interfaces, and application co-hosting. We found that a system implementing all of these solutions concurrently offers maximum flexibility, but a system that, at a minimum, implements FACE and ARINC 661 is an efficient way to enhance an avionics system to support Third Party Development.

This study is focused on the improvement of UH-60A blade structural loads correlation with flight and wind-tunnel test data. The blade airloads prediction has been proven to be reasonably good from past studies. However, the blade structural loads, especially the edgewise bending moment, were poorly predicted, and these are the subject of the current study. Several variations of modeling effort have been examined. This includes the drive-train model, refined grid, lag-damper model variation, hub impedance with test stand, tunnel wall, and dis-similar blades. The drive-train and refined grid showed noticeable improvement in edgewise bending moment, but not enough to close the gap between measured data and prediction. A lag damper study indicated that the current nonlinear damper seems to be adequate, and variations to the lag damper had a limited impact to inboard region only. The influence of dis-similar blades provides further insight into the sensitivity of the edgewise bending moment. The largest difference was observed to be due to the presence of the fuselage-like wind tunnel mount, indicating that a rotor analysis should include the fuselage.
