The analysis of individual tactics in the women's water polo

In water polo lacks a codified methodology for tactics training, which is thus only left to coach’s discretion. The aim of this study is to create a methodology that is to fill such vacancy. Aim of the work is to verify the efficacy of different attack patterns, in order to create a codified methodology for teaching water polo through tactics. The data, collected via video-analysis, were analyzed trough which returned basic descriptive statistics and the correlation coefficient of each pattern with events outcomes. The research approach is integrated and consists of 3 distinct methods: case study (9 matches of the Italian Serie A1 Women's Championship, for the analysis of matches, action research method for coach contribution, and theoretical-argumentative method to deduce a theoretical framework in which define the data processing. The data, collected via Dartfish TeamPro, for each athlete were established 4 patterns, we have provided quantitative data, we also have processed data from the analysis (qualitative) of the video. An evaluation table was constructed by combining, for each single event, the Boolean evaluation of the coach on the compliance of patterns with the event final outcome. Then were processed, Confrontations of pattern design with Dartfish screenshot of pattern implemented during game; Basic descriptive statistics. Linear regression scatter plot for single patterns; the survey of data is entrusted to performance analysis, carried out with the help of a water polo coach, a statistician and a performance analyst. The assessment of compliance for the tactical patterns is entrusted to the coach, on the basis of the video analysis-aided confrontation, of 4 patterns previously identified for each athlete in the relative phases of the game against pattern effectively implemented during match. A total of 186 Plate were analyzed, about 20 Plate every athlete. The results showed a general efficacy of tactical patterns, but showed significant differences within correlation coefficients of single patterns. A more consistent data base is needed, in order to establish direct, evident and general relationship between so calculated coefficient and pattern efficacy, and the research team is conscious of internal validity of this kind of qualitative analysis, which can’t extend, without adjustments, to other teams. Although, analysis results represents a tool for the coach, in order to better train team in next season, which were an aim of action research, and showed a general trend on tactical pattern efficacy, which will be deeply investigated in future works

Technical movements in archery

The archery is a typically closed skill sport. It is a "closed skill" sport characterized by repetition, as precise as possible, of a movement already known automated. The aim is to evaluate the effects of motor imagery practice in training. The motor imagery is a cognitive process of mental simulation of actions in absence of movement. There are two methods to improve skills learning through motor imagery: in first person and in third person. The biological basis on which the motor imagery theory is founded, is formed by: mirror neurons. It is an experimental approach and it consists of two steps. Both groups were videotaped in the execution of sport skills and evaluated, through a check list made by archery indicators: positioning phase, traction and aim, release and follow through in 4 level of descriptors by technicians every four months. A sample of archery team of children (9-11 years old) splitting in control and experimental groups, after a pre-assessment, performed by technicians, about technical skills through an evaluation grid prepared "ad hoc" on technical fundamentals taken into the study to form two homogeneous groups (Experimental group n = 10, control group n = 10). Experimental group using modeling video performed by a athletes of National Italian Archery Team could lead to significant changes in technical skills. Data recruit at starting, ongoing and final training program and their analysis, evaluation and comparison by control group show percentage of 9% better outcomes. Particularly, at final training shows a minimum improvement 3.2% than ongoing phase that gives a maximum improvement 9.6%, while a substantial balance in the control group with a medium improvement of 3.2% in every phase of training program. In this study two basic aspects of the performance are examined: the motor execution and the motor imagine. Both share the same neuromotor mechanism: the motor imagery. Concerning the woman artistic gymnastics, it can be useful during the training and the race. So providing the athletes and trainers of a means which uses the motor imagery as a possible application for the improvement of the performance. So in conclusion, the study aims to provide a standard training feasible on a large scale to train the cognitive and physical abilities of an athlete and provide a support tool in the race in order to improve performance, optimize time and to reduce the margin of error

Unifying static analysis of gravitational structures with a scale-dependent scalar field gravity as an alternative to dark matter

Aims. We investigated the gravitational effects of a scalar field within scalar-tensor gravity as an alternative to dark matter. Motivated by chameleon, symmetron and f(R)-gravity models, we studied a phenomenological scenario where the scalar field has both a mass (i.e. interaction length) and a coupling constant to the ordinary matter which scale with the local properties of the considered astrophysical system. Methods. We analysed the feasibility of this scenario using the modified gravitational potential obtained in its context and applied it to the galactic and hot gas/stellar dynamics in galaxy clusters and elliptical/spiral galaxies respectively. This is intended to be a first step in assessing the viability of this new approach in the context of "alternative gravity" models. Results. The main results are: 1. the velocity dispersion of elliptical galaxies can be fitted remarkably well by the suggested scalar field, with model significance similar to a classical Navarro-Frenk-White dark halo profile; 2. the analysis of the stellar dynamics and the gas equilibrium in elliptical galaxies has shown that the scalar field can couple with ordinary matter with different strengths (different coupling constants) producing and/or depending on the different clustering state of matter components; 3. elliptical and spiral galaxies, combined with clusters of galaxies, show evident correlations among theory parameters which suggest the general validity of our results at all scales and a way toward a possible unification of the theory for all types of gravitational systems we considered. All these results demonstrate that the proposed scalar field scenario can work fairly well as an alternative to dark matter.Comment: 23 pages, 15 figures, 5 tables, accepted for publication on Astronomy & Astrophysic

30Cappa - The “Christmas” decree in kilometres

Following the COVID-19 pandemic emergency, in mid-December 2020 the Italian government introducedtravel restrictions during the Christmas holidays. In the implemented policies there was an exception:citizens of a municipality of up to 5,000 citizens can move within an area of 30 kilometers from their respectiveborders. This policy was used again in the following months to manage travel during the pandemic.30Cappa is a data visualization created by three civic hackers to give citizens the opportunity to understandthis policy (”cappa” is the pronunciation of the letter ”k” in Italian and means ”km”). The project consistsof a website where it is possible to receive information on the matter and the cartographic representationof the municipalities that correspond to the exception. The site has reached 350,000 unique visitors in twomonths and there has been a lot of talk about it in the media. This work highlights how the transformationof a policy into a tangible product such as a map created with the open data available, becomes an effectivetool to guide citizens and also to review the policies themselve

Performance improvement through motor imagery study of the case in artistic gymnastics

The motor imagery is a cognitive process of mental simulation of actions in absence of movement. There are two methods to improve skills learning trough motor imagery: in first person and in third person. The biological basis on which the motor imagery theory is founded by mirror neurons. The aim wants to evaluate the effects of motor imagery practice in training, so it verifies the effects on the skills. The method is experimental and it consists of two steps subsequently. To administrate the questionnaire at athletes in order to evaluate the perception of own skill, called round-off flic, and then to compare their perception with the evaluation of Italian federation of artistic gymnastics method. The data will be being compared with those of judge/technician. By the data there is a more effective internal evaluation and also an improvement in the performance on about 80% of the gymnasts that performed the round-off flic. Interpretation of data concerning evaluation of others emerged a lower outside awareness of the skills that is looked. The innovative aspect of this study is the use of hetero-evaluation tool. It is rarely used, but the data show improvements in the performance and ability to evaluate, after using for 5 months of this methodology. Another innovative aspect is the use of motor imagery in the third person. Finally, there’s and improvements learnings for about 80%. So, providing the athletes and trainers could use practice of motor imagery as a possible application for the improvement of the performance

Monitoring the on-farm welfare of sheep and goats

Schemes for on-farm welfare assessment in sheep and goats are not yet available. Factors responsible for this lack of availability are discussed in the first part of this review. Requisites for reliable methods of welfare assessment to be used in sheep and goat farms are discussed, taking into account the peculiarities of the small ruminant production systems in terms of flock management and farm location. Some housing parameters related to structures, design and micro-environment are reviewed and could be included in schemes of welfare assessment on farm. Human-animal interaction, health status of the animals in terms of body condition scoring, skin and hair conditions, lameness and injuries, and management practices in relation to cleanliness, animal handling and moving, milking procedures and abnormal behaviours, are proposed as potential animal-based indicators. When available, validity, reliability and feasibility of the proposed parameters are discussed. The voluntary adhesion to welfare standards in Sardinia and the application of a scientifically validated protocol in Basilicata are reported as examples of practical experiences

Gilteritinib and the risk of intracranial hemorrhage: a case series of a possible, under-reported side effect

Gilteritinib is currently approved for patients with relapsed/refractory AML with FLT3 mutations, based on the positive results of the pivotal ADMIRAL study. In ADMIRAL trial, no increased risk of bleeding was reported, but in the previous dose finding study, a single event of intracranial hemorrhage (ICH) was registered after exposure to subtherapeutic doses of gilteritinib. Here, we report the first case series on five ICHs diagnosed in patients with FLT3-mutated AML, occurred within the first month of exposure to gilteritinib. Our cohort included 24 patients treated in three Italian centers. Most of these ICH cases were non-severe and self-limiting, while one was fatal. This link with ICHs remains in any case uncertain for the presence of active AML. We further reported that an analysis of the post-marketing surveillance data (EudraVigilance) retrieved other 11 cases of ICHs present in the database after gilteritinib treatment. A causality assessment was performed according to the Dx3 method to evaluate the possibility that ICHs might be an actual side effect of gilteritinib. In conclusion, further research is needed to elucidate the potential role of gilteritinib in the pathogenesis of ICHs
