Coaching or presenting a task in a circuit or station formats for U10 players consists of a session of some 8-12 stations which can be completed roughly three times. The circuit may aim at the ...development and stimulus of both condition capabilities (strength, speed, endurance, flexibility), as well as coordination capabilities. This format assures variability in the game session.
Abstract
We study the geometry of smooth non-homogeneous horospherical varieties of Picard rank one. These have been classified by Pasquier and include the well-known odd symplectic Grassmannians. We ...focus our study on quantum cohomology, with a view towards Dubrovin’s conjecture. We start with describing the cohomology groups of smooth horospherical varieties of Picard rank one. We show a Chevalley formula for these and establish that many Gromov–Witten invariants are enumerative. This enables us to prove that in many cases the quantum cohomology is semisimple. We give a presentation of the quantum cohomology ring for odd symplectic Grassmannians. In the last sections, we turn to derived categories of coherent sheaves. We first discuss a general construction of exceptional bundles on horospherical varieties. We work out in detail the case of the horospherical variety associated to the exceptional group $G_2$ and construct a full rectangular Lefschetz exceptional collection in the derived category.

This case study on nine bilingual teachers in Texas during their first year in a graduate education program examines both the development of critical consciousness among the educators and the ways in ...which critical consciousness shapes how these teachers come to understand their roles as teachers and leaders of a sociopolitically marginalized student group and community. Our analysis supports the proposition that teacher leadership programs can influence the development of social justice leadership, and it suggests that engaging teachers in certain types of structured learning opportunities can promote risk taking and a willingness to assume responsibility through the development of a sense of agency and efficacy.

We provide a notion of algebraic rational cell with applications to intersection theory on singular varieties with torus action. Based on this notion, we study

-filtrable variety is freely generated by the classes of the cell closures. We apply this result to group embeddings, and more generally to spherical varieties.

We describe the equivariant cohomology ring of rationally smooth projective embeddings of reductive groups. These embeddings are the projectivizations of reductive monoids. Our main result describes ...their equivariant cohomology in terms of roots, idempotents, and underlying monoid data. Also, we characterize those embeddings whose equivariant cohomology ring is obtained via restriction to the associated toric variety. Such characterization is given in terms of the closed orbits.

Purpose: Educator evaluation systems have recently undergone scrutiny and reform, and district and school leaders play a key role in interpreting and enacting these systems. This article uses framing ...theory to understand district leaders’ interpretation and advancement of a state’s new educator evaluation policy. Research Methods: The article draws on qualitative data from 14 Connecticut districts to highlight the relationship between state policy, district leadership, and the ideas about educator evaluation making their way into schools. We employed frame analysis to systematically analyze interview data from district leaders responsible for evaluation reform. Findings: District leaders’ frames addressed two distinct elements of the evaluation policy: accountability and development. Overall, district leaders tended to emphasize the accountability aspects of the state’s new evaluation system—SEED (System for Educator Evaluation and Development). Second, we find that district leaders’ frames predominately issued solutions and advice regarding the implementation of the evaluation policy. These leaders rarely enforced their framing of SEED. Finally, we present a vignette to highlight how one elementary school principal encountered frames within his district context and elected to respond to the ideas and rules of the new evaluation system. Implications for Research and Practice: This article’s findings encourage additional research on the role of district leaders in translating state policy into school-level change. This article also highlights the need for district-level actors to have a deep understanding of current policy as well as the skills to frame policy messages to diverse audiences.

ABSTRACTIn past and ongoing military conflicts, the use of whole blood (WB) as a resuscitative product to treat trauma-induced shock and coagulopathy has been widely accepted as an alternative when ...availability of a balanced component-based transfusion strategy is restricted or lacking. In previous military conflicts, ABO group O blood from donors with low titers of anti-A/B blood group antibodies was favored. Now, several policies demand the exclusive use of ABO group–specific WB. In this short review, we argue that the overall risks, dangers, and consequences of “the ABO group–specific approach,” in emergencies, make the use of universal group O WB from donors with low titers of anti-A/B safer. Generally, risks with ABO group–specific transfusions are associated with in vivo destruction of the red blood cells transfused. The risk with group O WB is from the plasma transfused to ABO-incompatible patients. In the civilian setting, the risk of clinical hemolytic transfusion reactions (HTRs) due to ABO group–specific red blood cell transfusions is relatively low (approximately 1:80,000), but the consequences are frequently severe. Civilian risk of HTRs due to plasma incompatible transfusions, using titered donors, is approximately 1:120,000 but usually of mild to moderate severity. Emergency settings are often chaotic and resource limited, factors well known to increase the potential for human errors. Using ABO group–specific WB in emergencies may delay treatment because of needed ABO typing, increase the risk of clinical HTRs, and increase the severity of these reactions as well as increase the danger of underresuscitation due to lack of some ABO groups. When the clinical decision has been made to transfuse WB in patients with life-threatening hemorrhagic shock, we recommend the use of group O WB from donors with low anti-A/B titers when logistical constraints preclude the rapid availability of ABO group–specific WB and reliable group matching between donor and recipient is not feasible.
