This study investigated developmental stability, or tracking, in the development of technical skills in youth male basketball players and retrospectively profiled stable and unstable tracking patterns over time. A total of 97 basketball players were tracked bi-annually over 3 consecutive years. Players were divided into two age-categories according to their age at baseline: under-12; and under-14. Technical skills were assessed using the American Alliance for Health, Physical Education, Recreation and Dance test battery. Anthropometric, body composition, biological maturation and physical performance data were collected. Cohen’s kappa (κ) was used to estimate tracking. With the exception of defensive movement in the under-12 age-category, tracking was low in all skill tests for both under-12 (0.22 ≤ κ ≤ 0.33) and -14 (0.20 ≤ κ ≤ 0.26) groupings. The overall technical skill showed moderate tracking for under-12 players (κ = 0.47) and low tracking for under-14 players (κ = 0.26). At baseline, players who were consistently more skilled or became more skillful (in the under-12 age-category) over time had a better growth-motor performance profile and most of them were selected to be members of regional teams. In conclusion, tracking of individual skill trajectories was low-to-moderate. Moreover, a better growth-motor performance profile seems crucial to maintain high levels of skill performance over time. It is recommended that basketball coaches track the developmental trajectories of their players to better understand the erratic nature of skill development and help design more effective practice regimes.

Although technical skills are a prerequisite for success in basketball, little is known about how they develop over time. In this study, we model the trajectories of technical skill development in young basketball players and investigate the effects of training experience, training volume, body composition, maturity status, physical performance, and club characteristics on skill development. A total of 264 male basketballers from five age-cohorts (11 to 15 years of age) were followed consecutively over three years using a mixed-longitudinal design. Technical skills, training experience and volume, basic anthropometrics, body composition, biological maturation and physical performance were assessed bi-annually. A multilevel hierarchical linear model was used for trajectory analysis. Non-linear trends (p < 0.01) were observed in speed shot shooting, control dribble, defensive movement, slalom sprint, and slalom dribble. Being more experienced and physically fitter had a significant (p < 0.05) positive effect on technical skill development; greater fat-free mass negatively affected skills demanding quick running and rapid changes of direction with or without the ball (p < 0.05). Training volume and biological age did not explain differences in technical skill development (p > 0.05). Moreover, belonging to different clubs had no significant influence on the technical skills trajectories of players. Our findings highlight the important role that individual differences play, over and beyond club structure, in developing skills. Findings improve our understanding on how technical skills develop during adolescence through training, growth, and biological maturation.

Background: The occurrence of a fire when implementing anesthesia is a high-risk, low-frequency event. The operating room is a high-stakes environment that has no room for error. Mixed reality simulation may be a solution to better prepare healthcare professionals. The purpose of this quantitative, descriptive study was to evaluate the technical and non-technical skills of student registered nurse anesthetists (SRNAs) who participated in a mixed reality simulation of an operating room fire. Methods: Magic Leap OneTM augmented reality headsets were used by 32 student registered nurse anesthetists to simulate an emergent fire during a simulated tracheostomy procedure. Both technical and non-technical skills were evaluated by faculty members utilizing a checklist. Results: The SRNAs’ overall mean technical skill performance was 18.16 ± 1.44 out of a maximum score of 20, and the mean non-technical skill performance was 91.25% out of 100%. Conclusions: This study demonstrated the utility and limitations in applying novel technology in simulation. Participants demonstrated a strong performance of technical and non-technical skills in the management of a simulated operating room fire. Recommendations for future applications include the use of multiple sensory inputs into the scenario design and including all core team members in the immersive mixed reality environment.

This study aimed to investigate the effect of the Korean Advanced Life Support (KALS) education program on the non-technical skills and technical skills of nursing students. This one-group pretest–posttest experimental study included 46 participants who were fourth year nursing students at Shinsung University located in Dangjin-si, Chungcheongnam-do Province, Republic of Korea. Data were collected in April 2021 and analyzed via SPSS/WIN 25.0, using a paired samples t-test. The current study results report a significant improvement in the non-technical skills from 30.58 to 47.16 points (t = −5.892, p < 0.001). Furthermore, KALS training improved communication confidence from 23.45 to 35.77 points (t = −6.563, p < 0.001), critical thinking tendency from 96.71 to 107.16 points (t = −3.352, p = 0.002), and self-efficacy in performing cardiopulmonary resuscitation from 33.56 to 49.81 points (t = −13.242, p < 0.001). Lastly, technical skills also improved from 18.35 to 27.94 points (t = −28.439, p < 0.001). Therefore, the findings indicate that KALS education was effective in improving the non-technical and technical skills of these nursing students. However, this study did not analyze the effect of the stress level experienced by the study participants in emergency situations on their non-technical and technical skill performance. Thus, future studies should verify the effect of external stressors, caused by unpredictable emergencies, on non-technical and technical skill performance.

Abstract Objective This study developed an assessment tool that was based on the objective structured assessment for technical skills principles, to be used for evaluation of surgical skills in cortical mastoidectomy. The objective structured assessment of technical skill is a well-established tool for evaluation of surgical ability. This study also aimed to identify the best material and printing method to make a three-dimensional printed temporal bone model. Methods Twenty-four otolaryngologists in training were asked to perform a cortical mastoidectomy on a three-dimensional printed temporal bone (selective laser sintering resin). They were scored according to the objective structured assessment of technical skill in temporal bone dissection tool developed in this study and an already validated global rating scale. Results Two external assessors scored the candidates, and it was concluded that the objective structured assessment of technical skill in temporal bone dissection tool demonstrated some main aspects of validity and reliability that can be used in training and performance evaluation of technical skills in mastoid surgery. Conclusion Apart from validating the new tool for temporal bone dissection training, the study showed that evolving three-dimensional printing technologies is of high value in simulation training with several advantages over traditional teaching methods.

Although high and simulated altitude training has become an increasingly popular training method, no study has investigated the influence of acute hypoxic exposure on balance in team-sport athletes. Therefore, the purpose of this study was to investigate whether acute exposure to normobaric hypoxia is detrimental to balance performance in highly-trained basketball players. Nine elite and nine sub-elite male basketball players participated in a randomized, single-blinded, cross-over study. Subjects performed repeated trials of a single-leg balance test (SLBT) in an altitude chamber in normoxia (NOR; approximately sea level) with FiO2 20.9% and PiO2 ranging from 146.7 to 150.4 mmHg and in normobaric hypoxia (HYP; ~3,800 m above sea level) with FiO2 13.0% and PiO2 ranging from 90.9 to 94.6 mmHg. The SLBT was performed three times: 15 min after entering the environmental chamber in NOR or HYP, then two times more interspersed by 3-min rest. Peripheral oxygen saturation (SpO2) and heart rate (HR) were recorded at four time points: after the initial 15-min rest inside the chamber and immediately after each SLBT. Across the cohort, the balance performance was 7.1% better during NOR than HYP (P &lt; 0.01, ηp2 = 0.58). However, the performance of the elite group was not impaired by HYP, whereas the sub-elite group performed worse in the HYP condition on both legs (DL: P = 0.02, d = 1.23; NDL: P = 0.01, d = 1.43). SpO2 was lower in HYP than NOR (P &lt; 0.001, ηp2 = 0.99) with a significant decline over time during HYP. HR was higher in HYP than NOR (P = 0.04, ηp2 = 0.25) with a significant increase over time. Acute exposure to normobaric hypoxia detrimentally affected the balance performance in sub-elite but not elite basketball players.

This article presents and analyses certain playing characteristics of men's and women's 3 × 3 basketball in relation to shooting at the basket. Our intention was to compare this young and developing basketball discipline with the more established and traditional 5v5 basketball. For this purpose, over 400 matches were analysed in the U18 age category during the men’s and women’s European Championship (5v5 Basketball) and the Youth Olympic Games (3 × 3 Basketball). The research confirms some differences in the efficiency and structure of shooting. It can generally be said that male and female 3 × 3 basketball players take more long-distance shots (behind the 6.75 m line) and take fewer free throws than their counterparts in 5v5 basketball. When shooting from behind the 6.75 m line, both male and female 3 × 3 basketball players are less efficient than their 5v5 basketball counterparts, and similar applies to free throws. The reasons for these differences may entail many factors, including differences in the game rules, the playing conditions on outdoor courts, different technical and tactical requirements and the characteristics (style) of playing as well as the quality and performance level of basketball players.

Most libre (free, open source) software projects rely on the work of volunteers. Therefore, attracting people who contribute their time and technical skills is of paramount importance, both in technical and economic terms. This reliance on volunteers leads to some fundamental management challenges: Volunteer contributions are inherently difficult to predict, plan, and manage, especially in the case of large projects. In this chapter we present an analysis of the evolution over time of the human resources in large libre software projects, using the Debian project, one of the largest and most complex libre software projects based mainly in voluntary work, as a case study. We have performed a quantitative investigation of data corresponding to roughly seven years, studying how volunteer involvement has affected the software released by the project, and the developer community itself.

Colleges and universities are adept at teaching students in the academic sense. Often what is lacking in a student’s education is a thorough grasp of the “real world”; how their chosen field actually functions and operates. One way for students to gain an understanding of a particular occupation is to interact with a mentor. Mentors can offer valuable intellectual resources to students (O’Neil & Gomez, 1996). Regardless of the quality of their education, students still need the practical information that can only be provided by a working professional who can present students an awareness of the real world (O’Neil, 2001). A mentor, however, is much, much more than a professional with unique expertise in a specific vocation. While mentors do provide career knowledge and the means for technical skill development, mentors can offer a myriad of services. They provide support, encouragement, and guidance. Mentors act as role models, teaching and nurturing students, demonstrating appropriate skills and behaviors. They are friends to students, providing them a means to network and find jobs.

Background: We report the rationale and design for a peer-evaluation protocol of attending congenital heart surgeon technical skill using direct video observation. Methods: All surgeons contributing data to The Society of Thoracic Surgeons—Congenital Heart Surgery Database (STS-CHSD) are invited to submit videos of themselves operating, to rate peers, or both. Surgeons may submit Norwood procedures, complete atrioventricular canal repairs, and/or arterial switch operations. A HIPPA-compliant website allows secure transmission/evaluation. Videos are anonymously rated using a modified Objective Structured Assessment of Technical Skills score. Ratings are linked to five years of contemporaneous outcome data from the STS-CHSD and surgeon questionnaires. The primary outcome is a composite for major morbidity/mortality. Results: Two hundred seventy-six surgeons from 113 centers are eligible for participation: 83 (30%) surgeons from 53 (45%) centers have agreed to participate, with recruitment ongoing. These surgeons vary considerably in years of experience and outcomes. Participants, both early and late in their careers, describe the process as “very rewarding” and “less time consuming than anticipated.” An initial subset of 10 videos demonstrated excellent interrater reliability (interclass correlation = 0.85). Conclusions: This study proposes to evaluate the technical skills of attending pediatric cardiothoracic surgeons by video observation and peer-review. It is notable that over a quarter of congenital heart surgeons, across a range of experiences, from almost half of United States centers have already agreed to participate. This study also creates a mechanism for peer feedback; we hypothesize that feedback could yield broad and meaningful quality improvement.

Abstract –Given the ubiquity of teamwork in engineering education and industry1, developing teamwork skills in undergraduate students is a critical component of their training. This is supported by the inclusion of ‘individual and teamwork’ as a graduate attribute by the Canadian Engineering Accreditation Board2. The current work explores the development of teamwork skills through the use of multiple administrations of peer feedback, in order to explore the value of using several administrations and support past findings that have suggested increased administrations provide incremental improvements. Additionally, the paper discusses the use of an empirically validated and user-friendly tool used to deliver the peer feedback assessments. The results suggest that students find the tool easy to use and that they believed the feedback they received and gave was accurate and useful. Together, these results suggest that peer feedback, delivered using the ITPMetrics.com platform, is an effective and well-received method of fostering soft-skill development in engineering students.
