Short Paper Number 1

A.) “The optic nerve, for example, bundles a million axon fibers into a single cable carrying the messages each eye sends to the brain” (Mason and Kandel, 1991) P.55

B.) Mason, C., and Kandel, E.R. (1991. Central visual pathways . In E.R. Kandel, J.H. Schwartz, and T.M. Jessell. Principles of neural science (3rd. ed.) New York: El sevier.

C.) This sentence was very interesting to me mainly because I did not know the optic nerve has a million axon fibers in it. Also I never though about the fact that our eyes our constantly sending messages to our brains. Obviously it remains logical just never took the time to think about it. In addition, our eyes our how we process information and the idea of our brains being interconnected with our eyes ultimately through axon fibers is very intriguing. I went and found the original, it was a very large textbook and I simply asked a guy at a work desk if he could help me. We search the reference in part b into the ECU library and went and got it.

D.) There was a ton of information in this textbook but the 2 facts the really stood out to me were 1. Our eyes allow us to perceive electromagnetic radiation reflected from objects. This is a pretty high light intensity that we can reflect which seemed pretty cool to me. And 2. The eyeball is an optical device for focusing light. This was pretty cool to find out that the eye can change the extent to which rays are bent and can focus images of objects that are various distances from the observer. I was not aware this was how eyes operate and functioned. I feel I have learned a lot from this short paper in regards to how eyeballs

Cost Cost

...Part of the process of pricing your product is including the costs of producing that product. Those costs include the direct and indirect costs associated with producing your product. Direct Costs Direct costs are costs that can be easily traced to a particular object (also called a cost object), such as a product, the raw materials used to manufacture a product, or the labor associated with the work to produce the product. If your company produces a widget and a production manager is hired to oversee production of that widget, then the production manager's salary is a direct cost. If you own a carpet cleaning business, which is a service organization, and you hire workers just to clean carpets, their wages are direct costs. Direct costs are often, but not always, variable costs. Variable costs increase as more units of the product are manufactured. As a result, raw materials are variable and direct costs. But, if there is a supervisor overseeing the manufacturing of this particular product, their salary is probably the same regardless of how much of the product is manufactured, so it is a fixed cost. Direct Materials and Direct Labor The most common direct costs are direct materials and direct labor. Direct materials are the materials that can be specifically identified with the product. If you are a furniture maker, your direct materials would be the wood that goes into making your furniture along with the nails, varnish, and other products that you apply specifically...

...CLASSIFICATION OF COSTS: Manufacturing We first classify costs according to the three elements of cost: a) Materials b) Labour c) Expenses Product and Period Costs: We also classify costs as either 1      Product costs: the costs of manufacturing our products; or 2      Period costs: these are the costs other than product costs that are charged to, debited to, or written off to the income statement each period. The classification of Product Costs: Direct costs: Direct costs are generally seen to be variable costs and they are called direct costs because they are directly associated with manufacturing. In turn, the direct costs can include: Direct materials: plywood, wooden battens, fabric for the seat and the back, nails, screws, glue. Direct labour: sawyers, drillers, assemblers, painters, polishers, upholsterers Direct expense: this is a strange cost that many texts don't include; but (International Accounting Standard) IAS 2, for example, includes it.  Direct expenses can include the costs of special designs for one batch, or run, of a particular set of tables and/or chairs, the cost of buying or hiring special machinery to make a limited edition of a set of chairs. Total direct costs are collectively known as Prime Costs and we can see that Product Costs are the sum of Prime costs and Overheads. Indirect Costs: Indirect costs are those costs that are incurred in the factory but that cannot be directly associate...

Costs

...Direct Costs vs. Indirect Costs Direct costs are any costs that are paid directly towards the material, labor, etc. of a product or service. Any cost associated with administrative needs, or ‘behind-the-scenes’ type costs, are known as indirect costs. Almost every venue of manufacturing, healthcare, or business in general has some form of indirect costs. Many times, these costs are overlooked when paying for a service or product. They are costs wrapped into the total cost of an item or service that you don’t normally think about. Direct costs are involved and associated with every service or product purchased, as are indirect costs, usually, even when you don’t think about it. Indirect costs affect the healthcare field, research, accidents, etc. Indirect costs in healthcare could be anything from administration to disability pay while a patient is off from work. “Indirect costs in published U.S. studies were based on estimates from physician panel and survey data and included loss of earnings associated with unemployment and underemployment, productivity losses, as well as loss of caregiver earnings not considered in this study” (Ivanova, Birnbaum, Kidolezi, Ying, Mallett, & Caleo, 2010). “Researchers have long been unhappy at the bite indirect costs take out of research grants, but have rarely taken direct action to control expenditures that determine those costs – indeed they may have felt powerless to do so” (Johnson, 1991). Building plans for Stanford University were...

...As a contraction officer, your primary objective is to acquire supplies and services from responsible and competent sources at a fair and reasonable price. As I have learned, doing this is no small task because all the companies you deal with only want you for one thing, to get awarded that contract by any means necessary. For that reason, that is why I choose comparison of proposed prices received in response to a solicitation as the price analysis method I would choose. Comparison of proposed prices received in response to a solicitation is the easiest of all the other preferred methods of performing price analyses. Some of the other choices were, Comparison to prior prices paid, comparison to prior quotes, comparison to prices paid for similar items, and use of estimating relationships (Murphy, 2009). A few of the benefits that I thought would make this kind of price analysis’s easier were the ease of the transactions; the contracting officer would send out a solicitation for supplier or a needed service, interested vendors would send in their bids and one a time frame is met in and then the contracting officer will choose the lowest bid. Sometimes the lowest bid does not always get awarded the contract, there could be errors in the bid which results would in a low bid from the vendor and the contracting officer will have no choice not to award the contract. Other times a contracting officer will award a company with a higher bid because they have more experience...

...CHAPTER 2 QUANTITY TAKE-OFF The quantity “takeoff” is an important part of the cost estimate. It must be as accurate as possible and should be based on all available engineering and design data. Use of appropriate automation tools is highly recommended. Accuracy and completeness are critical factors in all cost estimates. An accurate and complete estimate establishes accountability and credibility of the cost engineer, therefore, providing greater confidence in the cost estimate. The estimate contingencies for programming purposes reflect the estimate confidence. 2.1 Importance of Quantity Takeoff and Required Documents The quantity of material in a project can be accurately determined from the drawings. The estimator must review each sheet of the drawings, calculate the quantity of material and record the amount and unit of measure. Each estimator must develop a system of quantity takeoff that ensures that a quantity is not omitted or calculated twice. A wellorganized check-list of work will help reduce the chances of omitting an item. The estimator must, also, add an appropriate percentage for waste for those items where waste is likely to occur during construction. The material quantity takeoff is extremely important for cost estimating because it often establishes the quantity and unit of measure for the costs of labor and contractor’s equipment. 2.1.1 Contract documents The contract is defined by the contract documents, which are developed from...

...Cost Descriptions Paper Cost Descriptions One of the most common terms heard in the business world is fixed cost. Fixed costs do not depend on the amount of sales or the current level of production of a company. A fixed cost does not vary it remains the same every month. “By installing modern, sophisticated equipment, you can virtually eliminate labor in the production of inventory. At high volume, you will do quite well, as most of your costs are fixed. At low volume, however, you could face difficulty in making your fixed payments for plant and equipment” (Block & Hirt, 2004, p. 114). The lease payments on the building that houses a company is a fixed cost, always costing a set amount each month or quarter. Another common cost term is variable cost. Variable costs depending upon quantity produced or the amount of material used. An example of this would be a firm paying for its raw materials if they slow production less raw material is purchased lowering the variable cost. On the other hand if production speeds up more material must be purchased raising the variable costs. Combined fixed and variable costs make up total cost. Total cost is, simply put, the total economic cost of production. A mixture of fixed and variable costs is termed semi-variable costs. These costs are fixed up to a certain amount and once that amount has been reached the costs become variable. The greater the level of production the higher a semi-variable cost. An example of a semi-variable cost...

...Project #2 – Cost Accounting Classifications The first business I observed was Little Caesars. Little Caesars is a pizza chain, similar to Pizza Hut and Dominos. I met up with the store manager, Norma, so that she could show me around the store. We started at the back of the store where she introduced me to Omar and Miguel who have the very important job of making the dough every morning. We walked towards the front of the store where Paula was prepping toppings for the pizza and getting ready to dress some pizzas. Joseph was at the very front of the store and has a heavy work load. He is responsible for taking pizza orders, putting pizzas into the oven and taking them out, boxing the pizzas and ringing up customers. At this business, three direct materials in the product were dough, sauce and cheese. The dough maker and the pizza dresser are two people whose job function is classified as direct labor costs. Three manufacturing overhead costs that were clear to me from my direct observation were wages for the store manager, electricity to run the oven and the boxes used for the pizzas. Two manufacturing overhead costs that were not clear from my observation included the marketing of the pizza and the maintenance on the equipment. I believe this company would use process costing because they are producing the same product in large quantities on a daily basis. Based on my observation, the cost drivers for the overhead costs at this business would be the number of employees...

Annual Cost

...ANNUAL COST PURPOSE For investments (purchases) of buildings and equipment, which are expected to last several years, it is reasonable to place their cost on an annual basis over several years, rather than a single year. Viewing cost on an annual basis allows easy comparison to anticipated changes in income or productivity that will be required to pay for the item. For instance, if annual cost of a mix wagon is $3,000, then an equivalent increase in net milk income will cover its cost. For 100 cows at a n of $8/cwt of milk, that would et 350lbs/cow/year or slightly more than 1 lb/cow/day in milk. Furthermore, annual costs allows comparison or joint consideration of items having differing lengths of life. CALCULATION CONCEPT The annual cost includes charges for depreciation (purchase price minus salvage value), interest on the money invested, repairs for normal use, property taxes, and insurance. Repairs, property taxes, and insurance are usually rough estimates by percentage of price, with increases in repairs assumed to offset decreases in the other two. Interest is often loosely accounted for multiplying an average value of the item by an interest rate (discount, opportunity, MARR). This is crude and can be improved by using time value of money to convert price and salvage to an annual cost, which includes automatically both depreciation and interest. INFORMATION TO BE I NCLUDED 1. Purchase Price – to be annualized 2. Salvage Value – also to be annualized. Can be figured several...

College Cost

...College Costs Introduction It's no secret that financing a college education is getting tougher. College costs have skyrocketed over the past decade or so, and there's no relief in sight. Average tuition at four-year colleges will increase 7 percent this school year, double the rate of inflation. Student aid is not increasing fast enough to plug the growing gap between tuition and family finances. In addition, there is a growing number of older students entering college today. These students have families that they need to support. I know, because I am a family man who has returned to school. I wish to finish my degree at the Rochester Institute of Technology. The only problems I face are financial in nature. It is with this in mind that I set about this research. The not so simple question: Is financial aid available to older students, and if so, how do they go about obtaining it? The Cost Of Education The cost of higher education varies by type of institution. Tuition is highest at private 4-year institutions, and lowest at public 2-year institutions. The private 4-year colleges nearly quadrupled their average tuition rates between 1975 and 1996. For private 4-year colleges, tuition and fees for the 1995-96 academic year averaged about $15,400, compared with about $5006 at public 4-year colleges. The cost of attending an institution of higher education includes not only tuition and fees, however, but also books and supplies, transportation...
