Summary
Sport-related concussions (SRC) in hockey require action. Summit II prioritized eliminating head hits, modifying body-checking, and banning fighting to reduce concussions.
Area of Science:
- Exploration of the fundamental science behind sport-related concussions (SRC) in ice hockey.
- Building upon the action plan established at the Ice Hockey Summit I in 2011.
Background:
- The Ice Hockey Summit I (2011) aimed to reduce SRC through an initial action plan.
- Summit II convened in October 2013 to advance scientific understanding and develop new strategies.
Purpose of the Study:
- To review current scientific knowledge on SRC in hockey.
- To identify and prioritize strategies for reducing SRC based on expert consensus.
Main Methods:
- Summit II discussions covered basic science, acute/chronic care, prevention strategies (behavior, rules, education), equipment standards, and policy development.
- Prioritization of action strategies was determined through voting by invited faculty, comprising healthcare providers and clinical investigators.
Main Results:
- The Summit II action plan highlights the dynamic nature of SRC research in hockey.
- Key strategies for concussion reduction were identified and prioritized based on evidence and expert input.
Conclusions:
- The highest priority actions include eliminating head hits across all hockey levels.
- Modifying body-checking rules and prohibiting fighting in amateur and professional hockey are crucial steps.

00:49Impulse-Momentum Theorem
20.1K
The total change in the motion of an object is proportional to the total force vector acting on it and the time over which it acts. This product is called impulse, a vector quantity with the same direction as the total force acting on the object.
By writing Newton's second law of motion in terms of the momentum of an object and the external force acting on it, and simultaneously using the definition of the impulse vector, it can be shown that the total impulse on an object is equal to its...

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Ethical standards are the backbone of nursing practice, guiding nurses as they interact with patients, families, and colleagues. These standards are crucial for providing safe, empathetic care centered on the patient's needs.
Nurses are entrusted with upholding various ethical principles and standards. Nurses forge solid therapeutic relationships using trust, empathy, autonomy, confidentiality, and professional competence.
Confidentiality is crucial, embodying respect for individual privacy...

01:05Collisions in Multiple Dimensions: Introduction
7.5K
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a...
