Over the last decades positive development (PD) has served as a framework for several investigations within the sport science community. In fact, multiple researchers have analyzed youth coaches’ role in PD. However, there is recent interest in exploring high performance coaching due to the complexity of the coaching practice, the different developmental needs presented by players, and the relevance of PD within this particular environment. The purpose of this study was to understand the perspectives of Portuguese football coaches about the importance of PD in high performance coaching. The participants in the study were ten male Portuguese football coaches who trained athletes between the ages of 16 and 39 years of age. Findings showed that coaches viewed winning and on field performance as top priorities in their coaching philosophy, but recognized the importance of PD. Coaches also envisioned the determinant role youth coaches have in this domain. Coaches conceptualized PD as an overarching framework that could be used across the developmental spectrum to convey a range of PD outcomes in high performance contexts such as teamwork, respect for others and transfer to other life domains. Moving forward, coach education courses should help coaches develop strategies to foster PD.

Formal Recognition

The high-performance sports system is a rapidly evolving and increasingly important element of the Irish sporting landscape reflected in public policy, the direction and level of spending, and organisational/institutional evolution – all signalling a formal recognition of the high-performance sector as central to sport in Ireland. While certain aspects of high-performance sport in Ireland are beginning to be reflected in research (e.g., Guerin et al. 2008), this is yet to be extended to high performance coaching. The education, development, and support of coaches are key areas of the Coaching Strategy for Ireland (2008-2012). An understanding of high-performance coach activities and needs will become increasingly vital in underpinning the effectiveness of resources directed at high-performance coaching as Ireland seeks to reposition itself within the world’s elite in sport. The purpose of this article is to better understand the development of high-performance coaches in Ireland and the key influences on this (e.g., exposure to different coaching environments, sources of knowledge, and preferred ways of learning). It aims to explore what high-performance coaches believe has been most important in developing and fostering their coaching ‘know-how,’1 and what this may imply for future educational interventions for high-performance coaches. This article brings to light insights generated through semi-structured interviews with 10 high-performance coaches currently and/or recently working in Irish sport.

Education Courses

A frequent critique of coach education courses is that they are designed by scholars with little input from coaches about what they think they need. The purpose of this paper is to describe the design and content of a coach education course that was grounded in stakeholder needs. Dutch amateur football coaches felt ill-equipped to handle conflicts and confrontational behaviors by players and/or parents. Therefore a coach education course was created to help coaches develop tools they could use to improve their interpersonal skills. The tools were drawn from the teaching strategies of Forgatch and DeGarmo (1999) and Rational-Emotive Education (REE) (Knaus, 1974).

This paper considers the current status of physical education and sport science in Indonesia from the perspective of the development of the professional knowledge base and research culture surrounding its practice. It seeks to place the field’s development within the broader context of international sport studies from 1945 to 2020. It identifies as major influences the process of globalisation and the growth of international sport as a significant political and economic entity. Physical education is acknowledged as a common historical base for the three modern strands within contemporary sports studies – medical /and health science, high performance studies, and sports business management. Future developments are considered in the context of the current pandemic. Covid19 and the world’s response to it has impacted on some key dimensions which underpin the current global sports economy – namely easy and convenient travel and the gathering of crowds in the widespread consumption of live sport. It is suggested that this might cause a major reset in the conduct of elite sport and sport festivals. The continuing growth of the physical activity and health sector is predicted and in the context of the serious challenges facing the sporting sector a case is made for increased resources to be moved back into the educational study and practice of sport and physical activity as a universal good.

The One

When underground space requires excavation in areas below the water table, the foundation system suffers from buoyancy, which leads to the uplifting of the superstructure. A deep foundation system can be used; however, in cases where a hard layer is encountered, high driving forces and corresponding noises cause civil complaints in urban areas. Micropiles can be an effective alternative option, due to their high performance despite a short installation depth. Pressurized grouting is used with a packer to induce higher interfacial properties between micropile and soil. In this study, the field performance of micropiles installed using gravitational grouting or pressure-grouted using either a geotextile packer or rubber packer was comparatively evaluated by tension and creep tests. Micropiles were installed using pressure grouting in weak and fractured zones. As results, the pressure-grouted micropiles showed more stable and stronger behaviors than ones installed using the gravitational grouting. Moreover, the pressure-grouted micropile installed using the rubber packer showed better performance than the one using the geotextile packer.

Athletic Scholarships

Despite the financial and cultural importance of intercollegiate athletics in the United States, there is a paucity of research into how athletic scholarships are awarded. In this article, the authors empirically examine the factors that universities use in their decision to offer athletic scholarships to high school football players. Using a Zero-Inflated Negative Binomial (ZINB) model, the authors find a player’s weight, height, body mass index (BMI), race, speed, on-the-field performance, and his high school team’s success often have large and significant impacts on the number of scholarship offers he receives. There is also evidence of a negative relationship between academic performance and scholarship offers. In addition, the authors find evidence of a scholarship premium for players from Florida and Texas. The results also show that running backs, wide receivers, and defensive backs appear to generate the most attention from college football coaches, other things equal.

Abstract The present paper describes the results of the formulation of an acid-soluble low ECD organoclay-free invert emulsion drilling fluid formulated with acid soluble manganese tetroxide and a specially designed bridging package. The paper also presents a short summary of field applications to date. The novel, non-damaging fluid has superior rheology resulting in lower ECD, excellent suspension properties for effective hole cleaning and barite-sag resistance while also reducing the risk of stuck pipe in high over balance applications. 95pcf high performance invert emulsion fluid (HPIEF) was formulated using an engineered bridging package comprising of acid-soluble bridging agents and an acid-soluble weighting agent viz. manganese tetroxide. The paper describes the filtration and rheological properties of the HPIEF after hot rolling at 300oF. Different tests such as contamination testing, sag-factor analysis, high temperature-high pressure rheology measurements and filter-cake breaking studies at 300oF were performed on the HPIEF. The 95pcf fluid was also subjected to particle plugging experiments to determine the invasion characteristics and the non-damaging nature of the fluids. The 95pcf HPIEF exhibited optimal filtration properties at high overbalance conditions. The low PV values and rheological profile support low ECDs while drilling. The static aging tests performed on the 95pcf HPIEF resulted in a sag factor of less than 0.53, qualifying the inherent stability for expected downhole conditions. The HPIEF demonstrated resilience to contamination testing with negligible change in properties. Filter-cake breaking experiments performed using a specially designed breaker fluid system gave high filter-cake breaking efficiency. Return permeability studies were performed with the HPIEF against synthetic core material, results of which confirmed the non-damaging design of the fluid. The paper thus demonstrates the superior performance of the HPIEF in achieving the desired lab and field performance.

Injury Screening

In high-performance sport, science and medicine practitioners employ a variety of physical and psychological tests, training and match monitoring, and injury-screening tools for a variety of reasons, mainly to predict performance, identify talented individuals, and flag when an injury will occur. The ability to “predict” outcomes such as performance, talent, or injury is arguably sport science and medicine’s modern-day equivalent of the “Quest for the Holy Grail.” The purpose of this invited commentary is to highlight the common misinterpretation of studies investigating association to those actually analyzing prediction and to provide practitioners with simple recommendations to quickly distinguish between methods pertaining to association and those of prediction.

Abstract. Earth System Models (ESMs) are becoming increasingly complex, requiring extensive knowledge and experience to deploy and use in an efficient manner. They run on high-performance architectures that are significantly different from the everyday environments that scientists use to pre and post-process results (i.e. MATLAB, Python). This results in models that are hard to use for non specialists, and that are increasingly specific in their application. It also makes them relatively inaccessible to the wider science community, not to mention to the general public. Here, we present a new software/model paradigm that attempts to bridge the gap between the science community and the complexity of ESMs, by developing a new JavaScript Application Program Interface (API) for the Ice Sheet System Model (ISSM). The aforementioned API allows Cryosphere Scientists to run ISSM on the client-side of a webpage, within the JavaScript environment. When combined with a Web server running ISSM (using a Python API), it enables the serving of ISSM computations in an easy and straightforward way. The deep integration and similarities between all the APIs in ISSM (MATLAB, Python, and now JavaScript) significantly shortens and simplifies the turnaround of state-of-the-art science runs and their use by the larger community. We demonstrate our approach via a new Virtual Earth System Laboratory (VESL) Web site.

Abstract Motivation Combination therapy is widely used in cancer treatment to overcome drug resistance. High-throughput drug screening is the standard approach to study the drug combination effects, yet it becomes impractical when the number of drugs under consideration is large. Therefore, accurate and fast computational tools for predicting drug synergistic effects are needed to guide experimental design for developing candidate drug pairs. Results Here, we present TAIJI, a high-performance software for fast and accurate prediction of drug synergism. It is based on the winning algorithm in the AstraZeneca-Sanger Drug Combination Prediction DREAM Challenge, which is a unique platform to unbiasedly evaluate the performance of current state-of-the-art methods, and includes 160 team-based submission methods. When tested across a broad spectrum of 85 different cancer cell lines and 1089 drug combinations, TAIJI achieved a high prediction correlation (0.53), approaching the accuracy level of experimental replicates (0.56). The runtime is at the scale of minutes to achieve this state-of-the-field performance. Availability and implementation TAIJI is freely available on GitHub (https://github.com/GuanLab/TAIJI). It is functional with built-in Perl and Python. Supplementary information Supplementary data are available at Bioinformatics online.
