    In essences, Punctuated equilibrium is a system that studies and applies to particular situations such when political conflict is expanded beyond the confines of expert-dominated policy subsystems to other policymaking venues. In essence, punctuated equilibrium theory only extends current agenda-setting ideas to deal with both policy stasis and decision-making

    be broken down into smaller controlling factors. The global energy balance is an equal balance of short-wave radiation coming into the atmosphere and long-wave radiation going out of the atmosphere. This is called thermal equilibrium. The earth is at thermal equilibrium; however, there can have a surplus or deficit of energy in parts of the heat budget. If you have a net radiation surplus warm air will rise, and a net radiation deficit will make the air cool an fall. Air gets heated at the

  • Le Chatelier's Principle

    757 Words  | 2 Pages

    that if a change is made to a system in equilibrium, the system reacts in such a way as to tend to oppose the change, and a new equilibrium is formed. For example, whatever is done to the equilibrium, the system does the opposite. If something is added to a system at equilibrium, the system will behave as to remove it and vice versa. By increasing the concentration of a reaction, it will result in an increase of the rate of reaction. The new equilibrium will have a higher concentration of products

  • Consumer Equilibrium and the Law of Equi-Marginal Utility

    804 Words  | 2 Pages

    Consumer Equilibrium and the Law of Equi-Marginal Utility Introduction The Law of Equi-Marginal Utility is an extension to the law of diminishing marginal utility. The principle of equi-marginal utility explains the behavior of a consumer in distributing his limited income among various goods and services. This law states that how a consumer allocates his money income between various goods so as to obtain maximum satisfaction. Assumptions The principle of equi-marginal utility is based on the

  • Island Biogeography Theory

    718 Words  | 2 Pages

    In the review article, “Equilibrium Theory of Island Biogeography and Ecology”, Simberloff (1974) described how the equilibrium hypothesis can be used to explain island biogeography. According to the author, islands offer significant scientific, economic, evolutionary, or ecologic importances due to their unique characteristics (isolation, insular depauperization). However, detailed study on the somewhat puzzling island biogeography is limited. Therefore, Simberloff (1974) provided an in-depth research

    detached from the mass. The dots marked on the tape were examined. During the oscillation, the pendulum bob accelerated and then decelerated when it was approaching its highest position. The acceleration of the bob was always pointing towards its equilibrium position. 3. The two most widely spaced dots were marked on the tape - the zero position of the pendulum bob was found. 4. Every dot on the tape was marked from the zero position. The displacements of these points from the zero position

    molecules move. For example look at Figure 2. The solute molecules are too large to pass through the pores in the membrane, so the movement of water molecules can only achieve equilibrium. Solution A has the higher concentration of water; so there will be a net movement of water from A to B by osmosis. At equilibrium there will be no further net movement of water. The tendency of water molecules to move from one place to another is measured as the water potential, represented by the symbol

  • Investigating the Water Potential of Celery Cells

    Investigating the Water Potential of Celery Cells Aim === I will be investigating the water potential of celery and to find out which solution will be isotonic with the celery cells, in other words equilibrium between the two no water will leave the cell, or enter. I will do this by following this method. Method 1. Cut a 5 cm length of celery stem 2. Cut through the grooves to divide the stem into thin strips 3. Dry the cell sap from the strips using a paper towel 4.

    Investigate the Osmotic Point of Equilibrium in a Potato The following Passages are information which I have managed to find when researching the topic of Osmosis: - The cell membrane controls the movement of substances going into and out of the cells. The cell therefore controls the Chemical composition of the internal environment of the cell. It does this in two ways; Passive Process - this does not require energy Active Process - this does require energy to occur This works in principle which

    Landforms and Processes All rivers aim to reach equilibrium so they are balanced and when they are in equilibrium from source to mouth a smooth curve is created called the graded long profile. However, as you can see from the diagram many rivers such as The Afon Glaslyn, do not acheive equilibrium and reach their graded long profile: Long Profile of Afon Glaslyn River with graded long profile [IMAGE][IMAGE] Rivers become out of equilibrium when there is a change in base (sea) level. There

  • Making Moral Decisions: The Synergistic-Reflective-Equilibrium Model

    Making Moral Decisions: The Synergistic-Reflective-Equilibrium Model ABSTRACT: This treatise is a contribution towards the understanding of why humankind cannot agree on the foundation of morality and why moral pluralism is the logical constitution of moral reality. The synergistic-reflective-equilibrium model is the model that will describe how persons can make moral decisions as pluralistic agents. If this model is correct, then it will not be a new discovery, rather, it will be a new description

    offspring have the same genotype ratio as their parents. This example was one of Hardy-Weinberg equilibrium. The next generation will express the same genotype ratio as their parents, and so on. But what exactly is needed to create Hardy-Weinberg equilibrium? (Basically, a population in Hardy-Weinberg equilibrium s not evolving in any way.) Five specific factors are needed to create Hardy-Weinberg equilibrium within a population- a very large population, isolation from other populations, no net mutations

  • Freight Market Equilibrium Theory

    Freight Market Equilibrium Theory An amazing assortment of goods are moved over the worlds ocean trade routes. Of necessity, the carriers charge for the service they render. These charges vary almost as widely as do the cargoes, for they mirror both the shipowner’s costs and the special conditions prevailing on the trade routes traversed by the ships. Ocean freight rates may be described as the prices charged for the services of water carriers. Each ship operator develops it’s own rates, usually

    reaction. The desired product accumulates only if the equilibrium constant is favorable. As it happens, the equilibrium constant for this reaction is rather small (~4) (comparing bond energies in the reactants and products will tip you off as to why the equilibrium constant is so small). Therefore, simply mixing equal amounts of the starting materials will convert only about 67% of the starting material into product. To drive the equilibrium forward Le Chatelier's principle is used, in this case

    Vertigo and Its Treatment In our everyday lives, we almost take for granted this idea of balance or equilibrium that is maintained within our bodies. In general, no real thought processes are required. It is only when something is disturbed within our balance system that one is able to take notice of changes in the equilibrium. There may be several different factors that cause a disturbance to our bodies. One major area pertains to dizziness. Dizziness is found to be "the chief complaint in

The world is filled with pain, sorrow, and suffering, but wisdom can teach you how to maintain equilibrium and reduce misfortune. This was not wisdom in the modern sense, but rather it was wisdom in making choices that kept you along the right path while walking the slippery slope of the world. The Nauha conception of balance carries also into their
