Teaching and Learning Process of Decision-Making Units in Talented Young Players From U-10 to U-14.

ABSTRACT: There are multiple factors that have been studied for talent identification (TI) with regard to sport performance, such as physical and physiological parameters; psychological, social, and contextual parameters; and technical–tactical parameters. However, despite the importance of these indicators for reaching the elite, new trends seem to assure that one of the key elements in a young player is decision making (DM). Thus, in the last decades, research DM in young players has increased. Nevertheless, very little has been done in relation with DM and talented players. The purpose of this study was to analyze and compare the effectiveness, number, and duration of DM units (DMUs) of three groups of talented young players in U-10, U-12, and U-14 levels. Ninety-seven youth players participated in the study. A total of 1,087 actions were analyzed. The Nomination Scale for Identifying Football Talent was utilized to screen the talent pool (N = 18), and the Game Performance Evaluation Tool was used for analyzing the 1,087 actions completed. The results showed that the effectiveness has to be more than 80% for children to be considered talented. Moreover, a greater effectiveness of DMUs was shown in older age groups. The game speed also increased with age. It was revealed that U-12 did not follow the progression in the decisional demands in the formative stages. It is highlighted, therefore, the necessity of reviewing the organizational aspects in the U-12 age group, related mainly to the size of the pitch and the number of players, because it does not follow the same progression in regard to decisional demands. Future studies should follow this study with the U-16, U-18, and U-23 age groups, with the purpose of knowing the effectiveness, duration, and number of DMUs in older age groups. Furthermore, policy makers and teachers/coaches from both educational and soccer context must take these results into account, with the purpose of adjusting the teaching and learning process of talented children in sport.

Project description:BackgroundCaesarean section (CS) rates are rising. Shared decision making (SDM) is a component of patient-centered communication which requires adequate information and awareness. Women in Ghana have varying perceptions about the procedure. We sought to explore mothers' knowledge. perceptions and SDM-influencing factors about CSs.MethodsA transdisciplinary mixed-methods study was conducted at the maternity unit of Korle-Bu Teaching Hospital in Accra, Ghana from March to May, 2019. Data collection was done in four phases: in-depth interviews (n = 38), pretesting questionnaires (n = 15), three focus group discussions (n = 18) and 180 interviewer administered questionnaires about SDM preferences. Factors associated with SDM were analyzed using Pearson's Chi-square test and multiple logistic regression.ResultsMothers depicted a high level of knowledge regarding medical indications for their CS but had low level of awareness of SDM. The perception of a CS varied from dangerous, unnatural and taking away their strength to a life-saving procedure. The mothers had poor knowledge about pain relief in labour and at Caesarean section. Health care professionals attributed the willingness of mothers to be involved in SDM to their level of education. Husbands and religious leaders are key stakeholders in SDM. Insufficient consultation time was a challenge to SDM according to health care professionals and post-partum mothers. Women with parity ≥ 5 have a reduced desire to be more involved in shared decision making for Caesarean section. AOR = 0.09, CI (0.02-0.46).ConclusionThere is a high knowledge about the indications for CS but low level of awareness of and barriers to SDM. The fewer antenatal care visits mothers had, the more likely they were to desire more involvement in decision making. Aligned to respectful maternity care principles, greater involvement of pregnant women and their partners in decision making process could contribute to a positive pregnancy experience. Education, including religious leaders and decision- making tools could contribute to the process of SDM.

Project description:Aims: Chronic cannabis users show impairments on laboratory measures of decision making which reflect risk factors for initiation and continued use of cannabis. However, the differential sensitivity of these tasks to cannabis use has not been established. Moreover, studies to date have often lacked assessment of psychiatric histories and use of other illicit substances, both of which may influence decision making outcomes. The current study aimed to address these limitations by (1) including multiple types of decision making tasks, (2) implementing the Probabilistic Reversal Learning Task, a measure of decision making under uncertainty, for the first time in cannabis users, (3) including young adult cannabis users with no other psychiatric disorders, and (4) conducting urinalysis to exclude users of other illicit drugs. Methods: Thirty-three current cannabis users without comorbid psychiatric disorders and 35 cannabis non-users completed behavioral measures of decision-making (Iowa Gambling Task), reward discounting (Delay Discounting Task), choice-outcome learning (the Probabilistic Reversal Learning Task) and a questionnaire assessment of impulsivity (Barratt Impulsiveness Scale). Results: Relative to non-users, cannabis users demonstrated greater preference for immediate vs. delayed rewards on the Delay Discounting Task, made fewer advantageous decisions on the Iowa Gambling Task, and endorsed greater impulsivity on the Barratt Impulsiveness Scale scales. Cannabis users and non-users showed comparable performance on the Probabilistic Reversal Learning Task. Frequency of past-month cannabis use and total years of use did not predict decision making or impulsivity. Conclusions: Young adult cannabis users demonstrated higher discounting rates and impairments in learning cost-benefit contingencies, while reversal learning was unaffected. Self-reported impulsivity was elevated as well. None of these measures correlated with current or lifetime estimates of cannabis use, arguing against a dose-relationship. Interventions that target improvement in affected components of decision making may be helpful in reducing cannabis use and relapse.
