The water station in The Pond Room had always been a popular option especially since in this region the summer heat is extremely intense. The Master Teacher noticed that Zach, a 3-year-old with special needs and an IEP from the local school district, returned to the water station over and over again and was very focused on his activities. His obsession with water also drew other children in the play. After observing the children play freely with water for two weeks, the teacher decided to expand this water play into a series of developmentally appropriate, meaningful investigations about water. She felt that this water project was a great opportunity for preschoolers with and without disabilities to construct STEAM concepts and skills which will prepare them for more complex and abstract STEAM concepts in later schooling. With the goals of developing students’ knowledge and positive attitudes toward STEAM and promoting their STEAM-related questioning and problem-solving skills, the master teacher began the inquiry and embarked on a water project in her classroom.

A complex-valued data-based model with pth order autoregressive errors and general real/imaginary error covariance structure is proposed as an alternative to the commonly used magnitude-only data-based autoregressive model for fMRI time series. Likelihood-ratio-test-based activation statistics are derived for both models and compared for experimental and simulated data. For a dataset from a right-hand finger-tapping experiment, the activation map obtained using complex-valued modeling more clearly identifies the primary activation region (left functional central sulcus) than the magnitude-only model. Such improved accuracy in mapping the left functional central sulcus has important implications in neurosurgical planning for tumor and epilepsy patients. Additionally, we develop magnitude and phase detrending procedures for complex-valued time series and examine the effect of spatial smoothing. These methods improve the power of complex-valued data-based activation statistics. Our results advocate for the use of the complex-valued data and the modeling of its dependence structures as a more efficient and reliable tool in fMRI experiments over the current practice of using only magnitude-valued datasets.

The paper describes guidelines for the planning, organization, and successful execution of virtual, global scientific conferences for global audiences. The guidelines are based on experience and lessons learned during the organization of the 3‐day 2020 Virtual Systems Chemistry Symposium hosted on Zoom webinar and Twitter, held on May 2020 with over 1000 registered participants from 46 different countries. This planning guide outlines ten steps that academic organizers can follow to successfully organize and execute virtual, global scientific symposia for global audiences. The authors have also included instructional guides, videos, and PowerPoint slides that can be used as templates or inspiration for hosting virtual symposia with oral presentations on Zoom webinar and poster presentations on Twitter.

Background: Scaphoid reconstruction after an established non- or malunion is challenging and recent developments have shown the feasibility to reconstruct it with 3D-planned and -printed patient-specific instrumentation. Methods: Our study compared the clinical outcome of computer assisted 3D-reconstructions of the scaphoid using patient-specific guides for primary and revision reconstructions of scaphoid nonunion regarding clinical outcome. Therefore, 39 patients with primary scaphoid nonunion or malunion and 15 patients with nonunion or malunion after a previous operative treatment were treated with patient-specific guides and followed up for a mean of 10.5 months. The consolidation was assessed with a CT-scan, and the time to consolidation was recorded. Pain level, satisfaction, wrist range of motion, and grip strength were measured and compared. Results: The wrist range of motion and grip strength of the two groups were similar, except for the wrist extension, which was significantly reduced in the revision group. Consolidation was observed in 36/39 patients (92%) in the primary group and in 13/15 patients (87%) in the revision group. Our results showed similar clinical results postoperatively between primary reconstructions and revision surgery. Conclusions: The use of 3D-planned and -printed patient-specific instrumentation proves to be similarly effective in revision surgeries for the reconstruction of the scaphoid as it is in primary surgeries.

Developers, designers and operators are increasingly needing to create versatile sport and leisure amenities that are of lasting value to local and wider communities. Placing facilities design and operation at the heart of sports development, this book adopts a holistic approach, integrating experience in the field with collective knowledge across many different uses and technologies. Extensive use of case studies from around the world makes this book a definitive reference for practitioners and students in sports and leisure, building design and facilities management.

It's helpful to think of ''costumes''' rather than ''clothes.'' ... Women who travel a great deal have developed a four-costume, basic plan. With ''extras,'' it's suitable for a two-week vacation to Anywhere, U.S.A. It fits into one 26-inch suitcase plus an overnight case... Your travel suit... Your two-piece after-driving dress... A spectator sports ensemble... The rugged-life costume... In many resort areas, slacks are frowned upon -- more in the East than in the West, where they're quite generally accepted. If you're a passenger, you can help the driver and have a more enjoyable trip yourself by following a few simple rules. In general, let the driver do the driving. Leaning forward and breathing down the neck of the driver to tell him something doesn't help...Don't shout instructions or anything else which will distract the driver. If you're the ''navigator,'' give directions far enough in advance so that the driver has time to follow them easily. Above all, don't ''beef'' and don't tell the driver how you would have handled a tight situation. You can do it your way when you get the wheel. When the going gets rough -- in terms of behavior, not of the road -- there's a sure-fire remedy. It's called a ''mystery box.'' It's easy to make up and you'll never regret having one along. Simply wrap individually a few of the children's favorite toys plus some new, inexpensive ''surprises,'' and pack them in a box -- one box for each child. Then, at strategic moments of supreme boredom or on a prearranged schedule, let each child open his box and take out a toy.
