Talent identification and selection in soccer is typically based on subjective evaluations of experienced coaches. Recently, there has been a trend to complement these subjective assessments with objective tests. However, there is currently no comprehensive overview of the prognostic relevance of objective measurements in youth soccer. Therefore, the primary purpose of the current study was to systematically review published empirical studies related to the prognostic relevance of physiological (e.g. endurance and speed) and physical characteristics (i...

Residency selection is a perennial multifactorial process that differs considerably from the recruitment processes that other professional occupations enjoy. The 2016 meeting of the American Orthopaedic Association's Council of Orthopaedic Residency Directors highlighted a series of symposia that sought to present a novel manner of resident selection. Specifically, the presenters for each symposium were asked to do the following: present some general recruitment best practices in industries outside of medicine, present how branding of a program may translate into a better interview season, investigate evidence that the applicant pool to orthopaedic surgery may have changed and that residency program brands may have to reflect this, and assess our current evaluation techniques for talent identification and resident selection with respect to a specific department's appearance or brand...

Technological advances have changed the practice of clinical microbiology. We implemented Bruker MALDI-TOF and BD Kiestra Total Laboratory Automation (TLA) three and four years ago, respectively. To assess the impact of these new technologies, we compared turnaround times (TAT) for positive and negative urine cultures before and after implementation. Comparison I: TATs for 61,157 urine cultures were extracted for two periods corresponding to pre-TLA and post-TLA, both using MALDI-TOF for organism identification...

BACKGROUND: Talent identification (TID) programs are an integral part of the selection process for elite-level athletes. While many sport organizations utilize TID programs, there does not seem to be a clear set of variables that consistently predict future success. OBJECTIVE: This review aims to synthesize longitudinal and retrospective studies examining differences between performance variables in highly skilled and less-skilled athletes in elite-level sport. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to identify relevant studies (N = 20)...

The cognitive-motor performance (CMP), defined here as the capacity to rapidly use sensory information and transfer it into efficient motor output, represents a major contributor to performance in almost all sports, including soccer. Here, we used a high-technology system (COGNIFOOT) which combines a visual environment simulator fully synchronized with a motion capture system. This system allowed us to measure objective real-time CMP parameters (passing accuracy/speed and response times) in a large turf-artificial grass playfield...

The challenges in deaf education illustrate the requirement and importance of leadership in this specialized field. The significant and impending talent depletion unfolding as baby-boomers retire, positions leadership succession planning as a strategic issue. This mixed methods study is the first of its kind in New Zealand. The aim is to understand leadership demographics and assumptions to determine the need for strategic succession planning to identify and address leaky pipelines. The findings from 82% of the deaf education workforce through a questionnaire and interviews with seven senior leaders reveal that senior leaders do not appear aware of four key areas that dissuade and shrink the pool of potential leadership aspirants...

BACKGROUND: Lower limb explosive power is an important motor quality for sporting performance and indicates use of anaerobic energy systems like stored ATP and Creatine phosphate system. Weightlifting, Fencing and Wrestling use it for monitoring and identification of potential sportsmen. The Wingate test and Standing Broad Jump (SBJ) test are reliable and accurate tests for its assessment. This study conducted on elite Indian sportsmen tries to analyse feasibility of use of the SBJ test in sports and military medicine when Wingate test is impractical...

BACKGROUND: School attainment tests and Cognitive Abilities Tests are used in the United Kingdom to set targets for educational outcome. Whilst these are good predictors, they depend not only on basic ability but also on learnt knowledge and skills, such as reading. METHOD AND AIMS: VESPARCH is an online group test of verbal and spatial reasoning, which we propose gives a measure that more closely approximates to basic ability - fluid intelligence. The verbal test contains highly familiar words, does not require the child to read them, is untimed, and provides detailed feedback on five practice questions for each part of the test...

The incentives for sport organizations to identify talented athletes from a young age continue to grow, yet effective talent identification remains a challenging task. This opinion paper examines recent advances in talent identification, focusing in particular on the emergence of new approaches that may offer promise to identify talent (e.g., small-sided games, genetic testing, and advanced statistical analyses). We appraise new multi-disciplinary and large-scale population studies of talent identification, provide a consideration of the most recent psychological predictors of performance, examine the emergence of new approaches that strive to diminish biases in talent identification, and look at the rise in interest in talent identification in Paralympic sport...

In most sports, the development of elite athletes is a long-term process of talent identification and support. Typically, talent selection systems administer a multi-faceted strategy including national coach observations and varying physical and psychological tests when deciding who is chosen for talent development. The aim of this exploratory study was to evaluate the prognostic validity of talent selections by varying groups 10 years after they had been conducted. This study used a unique, multi-phased approach...

In recent years there have been major shifts in how the role of science-and scientists-are understood. The critical examination of scientific expertise within the field of Science and Technology Studies (STS) are increasingly eroding notions of the "otherness" of scientists. It would seem to suggest that anyone can be a scientist-when provided with the appropriate training and access to data. In contrast, however, ethnographic evidence from the scientific community tells a different story. Scientists are quick to recognize that not everyone can-or should-be a scientist...

The target article describes an interesting study, which provides some challenging findings regarding athletes' pathway to excellence. The suggested links between critical life events, need for success, personal characteristics, and eventual performance level make sense from a psychodynamic perspective. This commentary will discuss some critical points related to the application of the findings in talent identification and -development programs. These are (1) the possible effect of the selection of participants on the results (including the impact of dependence on others for team sport athletes and the opportunity for multiple medal attainment), (2) a lack of detail in the description of how the athletes approached the critical life events (the perception of an event may contribute more to development than the event itself), and (3) a lack of detail in the description of the practice process throughout development...

Rugby league is a collision team sport played at junior and senior levels worldwide, whereby players require highly developed anthropometric and physical qualities (i.e. speed, change-of-direction speed, aerobic capacity, muscular strength and power). Within junior levels, professional clubs and national governing bodies implement talent identification and development programmes to support the development of youth (i.e. 13-20 years) rugby league players into professional athletes. This review presents and critically appraises the anthropometric and physical qualities of elite male youth rugby league players aged between 13 and 20 years, by age category, playing standard and playing position...
