This paints a broad picture for my non-profit of how tutoring helps disadvantaged youth and, with the right jump-start from a caring individual (R1 point), how learning can get learning and skill begets further skill. I appreciate any feedback to modifications because they might shape program direction.

Future iterations will show the low skilled isolated individual gets stuck in a cycle of "no-growth." I would also like to explore the dynamics of how the learner reduces dependence on the tutor.

Physical meaning of the equations

The Lotka–Volterra model makes a number of assumptions about the environment and evolution of the predator and prey populations:

1. The prey population finds ample food at all times.

2. The food supply of the predator population depends entirely on the size of the prey population.

3. The rate of change of population is proportional to its size.

4. During the process, the environment does not change in favour of one species and genetic adaptation is inconsequential.

5. Predators have limitless appetite.

As differential equations are used, the solution is deterministic and continuous. This, in turn, implies that the generations of both the predator and prey are continually overlapping.[23]

Prey

When multiplied out, the prey equation becomes

dx/dt = αx - βxy

The prey are assumed to have an unlimited food supply, and to reproduce exponentially unless subject to predation; this exponential growth is represented in the equation above by the term αx. The rate of predation upon the prey is assumed to be proportional to the rate at which the predators and the prey meet; this is represented above by βxy. If either x or y is zero then there can be no predation.

With these two terms the equation above can be interpreted as: the change in the prey's numbers is given by its own growth minus the rate at which it is preyed upon.

Predators

The predator equation becomes

dy/dt = -

In this equation, {\displaystyle \displaystyle \delta xy} represents the growth of the predator population. (Note the similarity to the predation rate; however, a different constant is used as the rate at which the predator population grows is not necessarily equal to the rate at which it consumes the prey). {\displaystyle \displaystyle \gamma y} represents the loss rate of the predators due to either natural death or emigration; it leads to an exponential decay in the absence of prey.

Hence the equation expresses the change in the predator population as growth fueled by the food supply, minus natural death.

In this model I am trying to depict the multiple factors and interactions that impact student academic achievement. As educators, our goal is to optimize the progression of academic achievement, or as represented in this stock flow diagram maintain the stock (academic achievement) at the highest level. Multiple factors enhance achievement and, conversely, multiple factors interact to reduce the stock/rate of achievement. As individual teachers, we must understand the factors and relationships that increase and decrease achievement. In particular, teachers in training need to begin to build a mental model of these factors and relationships. Only then can we optimize our individual learning environments to ensure each child reaches his/her academic achievement potential.

Sistema de intervenção do Banco Central para regular a cotação do dólar. O sistema tem um loop que conduz naturalmente ao equilíbrio, isto é, a COTAÇÃO ATUAL tende, com o tempo, à COTAÇÃO DESEJADA pelo BC. Entretanto devido ao TEMPO DE REAÇÃO DO MERCADO, o sistema OSCILA mas ainda assim tende ao equilíbrio. Na verdade, o que faz a COTAÇÃO ATUAL oscilar, é a relação entre o TEMPO DE REAÇÃO DO MERCADO e o TEMPO DE AJUSTE da intervenção do BC. A frequência de oscilação é tanto maior quanto maior for a relação entre o TEMPO DE REAÇÃO DO MERCADO e o TEMPO DE AJUSTE do BC.

The purpose of this model is to explore the effect of time delays in the perception-action-system response on learning/convergence of stable goal seeking models in various contexts.

The goal of this model is to explore the effects of time delays between perception/processing of sensory input by people, actions chosen by those, and response of the environment and how fast the people are able to learn new skills. The hypothesis is that the shorter the time delay between when a person acts on sensory input from the environment, and when they receive and perceive whether their action was "correct" or "incorrect" by sensory signals from the environmental response to their action, the quicker the person will learn/refine the new skill(s) associated with the actions they are taking.

The probability density function (PDF) of the normal distribution or Bell Curve of Normal or Gaussian Distribution is the mean or expectation of the distribution (and also its median and mode).

The parameter is its standard deviation with its variance then, A random variable with a Gaussian distribution is said to be normally distributed and is called a normal deviate.

However, those who enjoy upskirts are called deviants and have a variable distribution :)

If the Higher Education Numbers Are Increased then the group decision making ability of society would be raised above that of a middle teenager as it is now

BUT

Governments can control children by using bad parenting techniques, pandering to the pleasure principle, so they will make higher education more and more difficult as they are doing

85% of the population has a qualification level equal or below a 12th grader, 17 year old ... the chance of finding someone with any sense is low (~1 in 6) and the outcome of them being chosen by those who are uneducated in the policies they are to decide is even more rare !!!

Experience means little if you don't have enough brain to analyse it

Democracy is only as good as the ability of the voters to FULLY understand the implications of the policies on which they vote., both context and the various perspectives. National voting of unqualified voters on specific policy issues is the sign of corrupt manipulation.

Democracy: Where a group allows the decision ability of a teenager to decide on a choice of mis-representatives who are unqualified to make judgement on social policies that affect the lives of millions.

The kind of children who would vote for King Kong who can hold a girl in one hand and swat fighter jets out of teh sky off the tallest building, doesn't have a brain cell or thought to call his own but has a nice smile and offers little girls sweets.
