    Sports coaching has used video feedback for decades to improve athlete and coach performance. More recently, artificial intelligence (AI) and machine-learning technologies have enabled analytics alongside visual review to accelerate development further. So too in coaching conversations, software allows the implementation of behavioural analytics, tracking speech patterns, body language and facial expressions to deliver performance data measured against core coaching competencies. In this study, we interviewed 15 coaches who used AI-enhanced video review software in coaching sessions with clients over several weeks and reflected on those sessions using the recordings and AI-generated data. Our aim was to discover the benefits and drawbacks of using such an approach in reflective practice. Clear benefits emerged: insights gained from video and data analysis drove deeper reflection and heightened self-awareness; coaches focused on skills development, made specific changes to their practice, developed over time and gained in confidence. Challenges included coaches’ nervousness around using new technology, viewing and analysing their own performance, and a sense that the software does not understand the subtle nuances and context of conversations. Limitations are discussed as well as the implications for coach training, reflective practice and supervision. We suggest possibilities for further study in this area

    Cost-effectiveness analysis of tropisetron vs. chlorpromazine-dexamethasone in the control of acute emesis induced by highly emetogenic chemotherapy in children

    To perform a cost-effectiveness analysis (CEA) between a standard antiemetic regimen-chlorpromazine + dexamethasone (CPM-DEX)- and a 5-HT3 receptor antagonist-tropisetron (TROP)--in the control of acute emesis induced by highly emetogenic chemotherapy in children, considering two analytic perspectives: hospital and patients. METHODS: The CEA was performed by constructing a decision tree, for both analytic perspectives, of the possible outcomes of treatment with TROP (single 0.2 mg/kg i.v.) or CPM (5-15 mg i.v. infusion for 3 doses) plus DEX (2 mg/m2 i.v. bolus i.v. x2). The patients were stratified by age in two groups (2-12 and 13-17). To estimate the probability of each endpoint at the decision tree we have taken as a base a trial developed in the Department of Pediatrics. Direct medical cost of primary therapy, failure, complications and side effects were included in the cost calculations. RESULTS: From patients' analytic perspective, TROP was more cost-effective than CPM-DEX for both groups of patients. Discrepancy between both analytic perspectives in 13-17 year-old patient's group was resolved in favour of the option chosen from the patients' analytic perspective (TROP). Sensitivity analysis showed the reliability of the results. CONCLUSIONS: 1. TROP was more cost-effective than CPM-DEX. 2. Taking into account the patients' analytic perspective is essential when we compare antiemetics pharmacoeconomically. 3. It seems necessary to increase the effectiveness of TROP in pediatric patients receiving highly emetogenic chemotherapy with strategies such as the addition of a steroid

    Who is a coach and who is a coaching psychologist? Professionalising coaching psychology in the United Kingdom

    Get PDF
    As the British Psychological Society establishes a new Division of Coaching Psychology and routes to chartered membership for coaching psychologists, we revisit the ongoing dialogue into the professionalisation of coaching psychology, with a specific focus on practice in the United Kingdom (U.K.). We attempt to make distinctions between the practice of a coaching psychologist and a professionally qualified coach. First, we offer an overview of the development of coaching psychology over recent years, contemplating the need to regulate it as a profession. Following that, we consider some of the main coaching and coaching psychology definitions in an attempt to delineate the practice of coaching psychologists from that of non-psychologist coaches. Next, we compare approaches to training and some of the differences between coaching and coaching psychology, as well as the need for an ethical framework and supervision for coaching psychologists. Finally, we conclude by offering a final thought about who is a coaching psychologist

    The aim of this study was to analyze the relationship between exposure to high-dose methotrexate (HDMTX) and tumor response in terms of survival in children with osteosarcoma. PROCEDURE: This study included 44 patients (479 courses) who received a median dose of 5.92 g/m2 of MTX (interquartile range (IQR) 2.37 g/m2) in a 4-hr infusion. The mean area under the concentration-time curve (AUC) estimated by parametric methods (non-parametric expectation maximization, NPEM), and the mean concentration at the end of the infusion were considered to be the exposure parameters. Tumor response was recorded as disease-free survival (DFS), overall survival (OS), and histologic tumor response. The relationship between MTX exposure and survival parameters was analyzed by Cox regression. RESULTS: The group of 11 patients who were the least exposed to MTX (AUC <2,400 micromol/L hr) presented a high DFS, probably due to the shorter interval of time between MTX courses that led to a higher dose density. In patients with AUC >2,400 micromol/L hr, an increase in the AUC was related to an increase in the DFS. Significant differences were observed in the DFS between patients whose mean AUC was below or above 4,000 micromol/L hr (P=0.024), such that 4,000 micromol/L hr was considered as the minimum AUC to be aimed at for future patients. CONCLUSIONS: Dose density seems to be an important factor in osteosarcoma response, but this must be confirmed in further studies. In order to improve the response to osteosarcoma in children, it is recommended that the dose of MTX to be increased such as to obtain an AUC higher than 4,000 micromol/L hr

    Get PDF
    This research presents and discusses the results of a Service-Learning project developed by student teachers of Primary Education at the University of Valladolid during the academic years 2016/17, 2017/18, 2018/19, and 2019/20. The project aimed to revitalize recess through musical activities for children aged 6 to 12 in seven schools in Segovia (Spain). The results of the qualitative analysis show that the project has promoted the musical development of the children through singing, the experience of rhythm, and expression through movement, using a selected repertoire of popular children folk songs. In the university students, it helped foster commitment to primary school students through the promotion of co-education and socio-cultural diversity—values which have fostered the development of social and civic competences. The student teachers also achieved professional growth by obtaining through this project skills typical of Music Education teachers

    Development of a methodology to categorize poultry meat affected by deep pectoral myopathy

    [EN] The growth of poultry production has led to an increase in the incidence of internal defects in chicken and turkey broilers, such as Deep Pectoral Myopathy (DPM). DPM is an ischemic hemorrhage or necrosis caused by the inadequate blood supply of Pectoralis minor and major muscles. Currently, visual appearance is the only parameter used to categorize the damage level. The aim of this research was to develop a scientific methodology to determine the level of damage in poultry breast tenders affected by this myopathy. For this purpose, microstructure, pH, protein and ion contents, and color were studied. Results allowed identifying three damage levels: normal, hemorrhagic samples with hematomas and blood clots, and necrotic tissues, based on significant variables (p < .05) measured in Pectoralis minor (pH, L* and a*), where muscles with myopathy presented L* values lower than 47, and necrotic muscles presented pH values higher than 6.05. Practical applications The appearance of defects in chicken meat is a growing problem due to the intensive genetic selection and the fast growth rate that the poultry industry demands. This research provides a scientific methodology, based on biochemical and physicochemical parameters of muscle tissue metabolism, and develops and validates a categorization for deep pectoral myopathy in broilers based on the level of muscle damage. This work, provides an objective and scientific methodology, and coupled with the work published in Traffano-Schiffo et al. (2018) and patented, will allow detecting, identifying, and characterizing chickens that have suffered deep pectoral myopathy and the degree of damage.Ministerio de Economia, Industria y Competitividad, Gobierno de Espana, Grant/Award Number: AGL2016-80643-R; European Regional Development FundTraffano-Schiffo, MV.; Chuquizuta, T.; Castro Giraldez, M.; Fito, PJ.

    [EN] In recent years, the general and scientific interest in nutrition, digestion, and what role they play in our body has increased, and there is still much work to be carried out in the field of developing sensors and techniques that are capable of identifying and quantifying the chemical species involved in these processes. Iron deficiency is the most common and widespread nutritional disorder that mainly affects the health of children and women. Iron from the diet may be available as heme or organic iron, or as non-heme or inorganic iron. The absorption of non-heme iron requires its solubilization and reduction in the ferric state to ferrous that begins in the gastric acid environment, because iron in the ferric state is very poorly absorbable. There are chemical species with reducing capacity (antioxidants) that also have the ability to reduce iron, such as ascorbic acid. This paper aims to develop a sensor for measuring the release of encapsulated active compounds, in different media, based on dielectric properties measurement in the radio frequency range. An impedance sensor able to measure the release of microencapsulated active compounds was developed. The sensor was tested with calcium alginate beads encapsulating iron ions and ascorbic acid as active compounds. The prediction and measurement potential of this sensor was improved by developing a thermodynamic model that allows obtaining kinetic parameters that will allow suitable encapsulation design for subsequent release.This research was funded by Spanish AGENCIA ESTATAL DE INVESTIGACIÓN, grant number PID2020-116816RB-I00.Tomas-Egea, JA.; Fito, PJ.; Colom Palero, RJ.; Castro Giraldez, M.
