...theory was proposed by Charles Darwin in the 19th century and it was affirmed by the 20th century biologists and geneticists. Thus, this theory has achieved scientific consensus as the origin of human humankind. In contrast, supporters of intelligent design believe that all life on the Earth was created deliberately. Intelligent design theory proposes that the overwhelming complexity of the universe suggests a rational, omnipotent designer, be it God, an alien, or some other source. Thus, intelligent design theory was developed as an alternative not only to Darwin’s evolutionism but also to religious creationism which argues that God is the only creator of life, universe and their contents. The Purpose of this Chapter • Our purpose in this chapter is not to show the truth or falsehood of any of these perspectives nor the doctrines of any particular faith.

...Chapter 3: Problems 2 & 4 2. What are some sources of risk in a systems analysis and design project, and how does a project manager cope with risk during the stages of project management? 2. Some sources of risk in a systems analysis and design project are resources, current technology, and rules and regulations. Sometimes, resources are not always available whether it be manpower or materials and software. Current technology can factor in as a risk because things can be outdated and might not be able capable of carrying out the work. Rules and regulations can prohibit certain codes from working because they might not follow the rules of code and regulations can prohibit certain things from happening during the entire process. A project manager copes with the risk during the stages of project management by acknowledging and understanding the risks that can be involved in the project. 4. Suppose that you have been contracted by a jewelry store to manage a project to create a new inventory tracking system. Describe your initial approach to the project.

...In section 1-2, there’s a “comic zoom-out” starting with a person sitting on a bench, this could be found in figures 1-2 through 1-13 (page 2-4). These photos are there to show us the proportion of objects in our everyday lives, in comparison to the size of earth, so that we can compare our earth to the size of the enormous universe. We notice that with each photo, the previous photo seems to be getting smaller and smaller until it is no longer visible. The field of view refers to the region you can see in the image. The angular distance is a measurement used by astronomers to tell the distance between two objects in the sky. For example, an astronomer might say, “the star was two degrees from the moon”. The ways this works is that; pretend there’s an imaginary line between your eyes and a star in the sky, then pretend there’s another imaginary line from your eyes to the moon. The distance between these two imaginary lines is the angular distance between two objects (view photo on page19). Units of angular distance: astronomers measure distances in degrees called ​-Arc minutes: 1/60th of a degree ​-Arc seconds: 1/60th of an arc minute The angular size/diameter of an object is the angular distance from one edge of the object to the other. The sun and moon are about half a degree in diameter, while the “bowl” of the big dipper is about 10 degrees wide. -The angular size of something is NOT equal to its true size. Astronomical unit (AU): is a unit of measurement, which......

...GM545 Week 3 Quiz Study Guide ------------------------------------------------- TOC-A Chapters 3 & 5 ------------------------------------------------- Given a demand function and a supply function, illustrate how the price mechanism, in response to changes in other demand or supply factors, leads to a new market equilibrium price and level of output. 1. ------------------------------------------------- Explain why the difference between the similar-sounding terms, quantity demanded and demand, is so critical to understanding the model of supply and demand. (P.58) Changes in Demand * Note that a change in demand is different from a change in quantity demanded. * A change in demand occurs when the entire curve shifts. * This means that the quantity demanded at every given price will be different from what it was before. Demand * Demand refers to the quantity of products people are willing and able to purchase during some specific time period, all other relevant factors being held constant. * Price and quantity demanded have an inverse relationship known as the Law of Demand, depicted as a downward-sloping curve. * A market demand is the horizontal sum of all of the individual demand curves. * Demand curves shift when one or more of the determinants of demand change. * The determinants of demand are: consumer tastes and preferences, income, prices of substitutes and complements, the number of buyers in a market, and......

...Case 3.2 – Service of Process Has Plaintiff properly served defendant Wal-Mart? No the plaintiff did not properly serve the defendant Wal-Mart. The plaintiff served the statue of limitation 9 days before the 3 years was up. He also served it to the manager that was physically available, but South Dakota has a law that the president, officer, director, or registered agent of a defendant corporation. The plaintiff as well did not properly give the service of process to the right person. Case 3.6 – Summary Judgment Should the court grant Pathmark’s motion for summary judgment? No I don’t think Pathmark established proper grounds for summary judgment. They are questioning the deposition of Toote, in the part where she stated she did not know how long the boxes were stacked there. How long the boxes being stacked is not the issue, it’s more an issue of negligence on Pathmark’s part because the boxes should not be laying around where people are walking. The court, due to not enough grounds of evidence, should not grant Pathmark requesting a summary judgment. Case 4.1 – Supremacy Clause Does the Massachusetts anti-Myanmar statue violate the Supremacy Clause of the U.S. Constitution? Under the Supremacy Clause, this anti-Myanmar act does violate the U.S., because it is going against the “supreme law of the land.” When Massachusetts set forward this, it went against the federal statute, making the state preempted by the federal statute. The states of the US don’t have to right...
