The development of a typology of abusive coaching behaviours within youth sport

Copyright @ 2010 Multi-Science Publishing.The purpose of this article was to create the Typology of Coaching Transgressions model (TOCT), which is concerned with abuse, neglect and violence in youth sport. Comments provided by the Justplay Behaviour Management Program from two competitive hockey associations and one large soccer association were analyzed and sorted to assess the utility of the model to capture inappropriate coaching behaviours. A total of 540 comments were examined deductively using the TOCT. Approximately 80% of coaching transgressions were of an indirect nature (i.e., not directed at the athlete specifically), indicating that young athletes are exposed to forms of abuse, neglect, and violence that may create harm in ways not yet fully understood. These findings illuminate the importance of understanding the nature and impact of coaching conduct on youth sport participants

Native and Naturalized Turf Species Suitable for Use on Airfields Managed for Wildlife Hazards in the Northeast

Habitat management is an important component of an integrated approach for reducing wildlife hazards on airfields. This research examines alternative turf species that are either native or naturalized in the northeastern United States. Many native turf species tend to not be attractive to wildlife due to their low palatability and seed production. These species may have uses on airfields, golf courses and in residential areas where geese and other wildlife are in conflict with humans. While the low seed productivity in some native species is a wildlife deterrent, this same trait is associated with poor establishment rates. Our goal was to find the most successful means of germinating these species using a hydroseeding application so they can be utilized as part of an airfield vegetation management design. Our data will show the evaluation of plant vigor conducted under controlled greenhouse conditions. Some of the species tested include Pennsylvania sedge (Carex pennsylvanica), little bluestem (Schizachyrium scoparium), crinkled hair grass (Deschampsia flexuosa), and purple love grass (Eragrostis spectabilis). By evaluating each species for their suitability for hydroseeding, germination, and early vigor we are able to make recommendations for hydroseeding native species at airfields managed for reducing wildlife hazards

Echoes of the electroweak phase transition: discovering a second Higgs doublet through A0 → ZH0

The existence of a second Higgs doublet in nature could lead to a cosmological first-order electroweak phase transition and explain the origin of the matter-antimatter asymmetry in the Universe. We obtain the spectrum and properties of the new scalars H0, A0, and H� that signal such a phase transition and show that the observation of the decay A0 → ZH0 at LHC would be a “smoking gun” signature of these scenarios. We analyze the LHC search prospects for this decay in the llbb¯ and llWþW− final states, arguing that current data may be sensitive to this signature in the former channel as well as there being great potential for a discovery in either channel at the very early stages of the 14 TeV run

Telecommunications systems design techniques handbook

Handbook presents design and analysis of tracking, telemetry, and command functions utilized in these systems with particular emphasis on deep-space telecommunications. Antenna requirements are also discussed. Handbook provides number of tables outlining various performance criteria. Block diagrams and performance charts are also presented

Hierarchical versus degenerate 2HDM: the LHC run 1 legacy at the onset of run 2

Current discussions of the allowed two-Higgs-doublet model parameter space after LHC run 1 and the prospects for run 2 are commonly phrased in the context of a quasidegenerate spectrum for the new scalars. Here, we discuss the generic situation of a two-Higgs-doublet model with a nondegenerate spectrum for the new scalars. This is highly motivated from a cosmological perspective since it naturally leads to a strongly first-order electroweak phase transition that could explain the matter-antimatter asymmetry in the Universe. While constraints from measurements of Higgs signal strengths do not change, those from searches of new scalar states get modified dramatically once a nondegenerate spectrum is considered

Deformed Heisenberg algebra and minimal length

A one-dimensional deformed Heisenberg algebra $[X,P]=if(P)$ is studied. We answer the question: For what function of deformation $f(P)$ there exists a nonzero minimal uncertainty in position (minimal length). We also find an explicit expression for the minimal length in the case of arbitrary function of deformation.Comment: to be published in JP
