What is the hill model of monitoring?
The Hill Model starts with the leadership decisions as to whether they monitor or take action based upon internal or external actions; all the while, focusing on the overall team effectiveness. The first step is for the leader to monitor or to take action. Information search and structuring are two phases in this initial search.

What are the 5 pursuits Gholdy Muhammad?
Muhammad spoke to Emily Freitag and Nicole Knight-Justice about five pursuits for teaching and learning that can serve as a guide for structuring education today: identity, skill development, intellectualism, criticality, and joy.
What does criticality mean in education?
Criticality is about using and questioning information rather than simply absorbing and then describing it. A critical mind is aware of the bigger picture: it locates information or ideas in broader contexts and tries to develop an understanding of the links existing between them.

What are the three elements of the Hill muscle model?
The model is constituted by a contractile element ( CE) and two non-linear spring elements, one in series ( SE) and another in parallel ( PE ). The active force of the contractile element comes from the force generated by the actin and myosin cross-bridges at the sarcomere level. It is fully extensible when inactive but capable of shortening when activated. The connective tissues ( fascia, epimysium, perimysium and endomysium) that surround the contractile element influences the muscle's force-length curve. The parallel element represents the passive force of these connective tissues and has a soft tissue mechanical behavior. The parallel element is responsible for the muscle passive behavior when it is stretched, even when the contractile element is not activated. The series element represents the tendon and the intrinsic elasticity of the myofilaments. It also has a soft tissue response and provides energy storing mechanism.
What is Hill's equation?
Hill's equation demonstrates that the relationship between F and v is hyperbolic.
Is Hill's equation hyperbolic?
Although Hill's equation looks very much like the van der Waals equation, the former has units of energy dissipation, while the latter has units of energy. Hill's equation demonstrates that the relationship between F and v is hyperbolic. Therefore, the higher the load applied to the muscle, the lower the contraction velocity. Similarly, the higher the contraction velocity, the lower the tension in the muscle. This hyperbolic form has been found to fit the empirical constant only during isotonic contractions near resting length.
Is a viscous damper included in the model?
Muscles present viscoelasticity, therefore a viscous damper may be included in the model, when the dynamics of the second-order critically damped twitch is regarded. One common model for muscular viscosity is an exponential form damper, where
What are the drawbacks of Hill type muscle models?
One of the main drawbacks of the Hill-type models is that they do not account for the history dependency of the skeletal muscle force production, which is the effect of the “recent” contractile conditions of muscle on the produced force [39]. Despite these shortcomings, the Hill-type muscle model is widely used in musculoskeletal modeling and simulation platforms due to its simplicity and practicability.
What are the two types of muscle models?
Muscle modeling approaches can be classified into two groups, namely structural (or molecular) and phenomenological models . In structural models, which are also known as Huxley-type models [31], the internal mechanical and chemical events in the sarcomeres are taken into account. The number of cross-bridges between myofilaments (actin and myosin) and the involvement of titin determine the force production capability of the models. However, the classical structural models represent the high complexity and they are still far from the practical use in the human motion analysis. On the other hand, phenomenological (Hill-type) models are widely used to mimic the biomechanical behaviors of the MTUs by means of rheological elements [32, 33] ( Fig. 11.8). Hill-type muscle models consist of rheological elements (spring and/or dashpot) and a controlled black box representing the muscle contractile properties such as force-length and force-velocity relationships. Even though Hill-type models are not based on realistic muscle architecture and internal sequential events, the gross biomechanical behavior of MTU could be practically simulated by using this model with a low computational burden.
What is Figure 11.6?
Figure 11.6. Muscle models of shoulder as well as upper and lower arm.
Is Hill's model phenomenological or phenomenological?
We should recall that, at that time, the molecular mechanism of muscle contraction was still unknown. Therefore, Hill’s model is a purely phenomenological one, and as Abbott and Wilkie (1953) note ‘Several other 3-constant equations fit the force–velocity curve of muscle satisfactorily’.
Why is it important? (Significance)
When teachers engage students in the process of employing criticality, they move beyond critically thinking about a topic. They become change agents who are working toward social transformation.
How is this strategy implemented? (Steps to Implementation)
In order to transform and humanize a course, teachers can implement the HILL Model. This model focuses on students' histories, identities, literacies, and liberation. The HILL Model is an equity framework grounded in Black education.
What is the Hill plot?
A Hill plot, where the x-axis is the logarithm of the ligand concentration and the y-axis is the transformed receptor occupancy. X represents L and Y represents theta. The Hill plot is the rearrangement of the Hill–Langmuir Equation into a straight line.
What is the Hill equation used for?
The Hill equation can be used to describe dose-response relationships, for example ion channel open-probability (P-open) vs. ligand concentration.
What is the Hill coefficient?
The Hill coefficient,#N#n {displaystyle n}#N#or#N#n H {displaystyle n_ {H}}#N#, may describe cooperativity (or possibly other biochemical properties, depending on the context in which the Hill–Langmuir equation is being used). When appropriate, the value of the Hill coefficient describes the cooperativity of ligand binding in the following way: 1 n > 1 {displaystyle n>1}#N#. Positively cooperative binding: Once one ligand molecule is bound to the enzyme, its affinity for other ligand molecules increases. For example, the Hill coefficient of oxygen binding to haemoglobin (an example of positive cooperativity) falls within the range of 1.7–3.2. 2 n < 1 {displaystyle n<1}#N#. Negatively cooperative binding: Once one ligand molecule is bound to the enzyme, its affinity for other ligand molecules decreases. 3 n = 1 {displaystyle n=1}#N#. Noncooperative (completely independent) binding: The affinity of the enzyme for a ligand molecule is not dependent on whether or not other ligand molecules are already bound. When n=1, we obtain a model that can be modeled by Michaelis–Menten kinetics, in which#N#K D = K A = K M {textstyle K_ {D}=K_ {A}=K_ {M}}#N#, the Michaelis–Menten constant.
What is the difference between Hill and Langmuir?
The distinction between the two Hill equations is whether they measure occupancy or response . The Hill–Langmuir equation reflects the occupancy of macromolecules: the fraction that is saturated or bound by the ligand. This equation is formally equivalent to the Langmuir isotherm. Conversely, the Hill equation proper reflects the cellular or tissue response to the ligand: the physiological output of the system, such as muscle contraction.
What is the horizontal axis of the Hill equation?
The horizontal axis is the concentration of the ligand. As the Hill coefficient is increased, the saturation curve becomes steeper. In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration.
What is the Katz model used for?
The Del-Castillo Katz model is used to relate the Hill–Langmuir equation to receptor activation by including a second equilibrium of the ligand-bound receptor to an activated form of the ligand-bound receptor.
What is the horizontal axis of a binding curve?
The vertical axis displays the proportion of the total number of receptors that have been bound by a ligand. The horizontal axis is the concentration of the ligand. As the Hill coefficient is increased, the saturation curve becomes steeper.
