Parasitic Crab Lab
Background:
Mellita quinquiesperforata, commonly known as the sand dollar, is a familiar urchin on Florida coastlines. The species is flat and disk shaped that nestles into shallow sandy waters to protect itself from waves and predators. Dissodactylus mellitae is a parasitic crab that feeds on the spines of the hosting sand dollar where it remains its entire life. This study was arranged to observe the distribution patterns of crabs on various sizes of sand dollars. We hypothesized that the larger sand dollars would host more crabs because of the extended surface area available. We also predicted that the presence of adult sized crabs would limit the number of total crabs on the hosting sand dollar because of the larger size and resource demand leading to intraspecific competition among the crabs. Intraspecific competition occurs when members of the same species compete over limited resources considered vital for survival. These resources can be food, space, light, mates, anything necessary for the survival and reproduction of the individual. In our study the factors of interest are space and food.

Methods:
We began our study by surveying Ft. DeSoto’s East beach for sand dollars and their parasites. In order to avoid duplicate data collection we began 100m offshore and worked our way bacl towards the shore placing all collected samples behind us after recording the data. For each sand dollar collected, we measured its diameter and counted the number of adult and juvenile crabs present on it. Adult crabs were considered to have a width of 2mm or more and juvenile crabs were considered anything below that. We surveyed the area until approximately 100 sand dollars were collected before returning to analyze the data.

Results:
Our results showed that there is no strong correlation between the size of sand dollars and the number of crabs present. When analyzing graph 1 I noticed that...

...The SandDollar
Splash!! Of course it’s me being picked up by every human and throwing me as far away out as possible. It gets me very angry and annoyed because the humans don’t treat me with enough respect as some other organisms living here. Humans don’t look at me as a living creature and I have the same systems and some of the same body parts as them but I’m just a lot smaller in size. They get angry at me for trying to get away using my spines to move along the sand. People who pick me up don’t even attempt to look at me and just think I’m not even a living creature. Everyday humans in general throw me around like I am a toy but I have qualities they have also but don’t realize. I always ask myself “Why can’t I be one of those things left on the sand and not get thrown around with?” I wake up every day down and feeling miserable because I am so overlooked its misfortunate.
There are constant questions about why I’m always overlooked. I think I am amazing and have great things to show forth towards humans. Are we to “boring” or “not as interesting” to study or at least look at? I mean everything on Earth has a unique thing to it and humans don’t understand that about us especially. We have a type of plant as our design which I think is very cool but it doesn’t seem to attract anyone besides me. Is it because we don’t have a circulatory, respiratory, and excretory system that we have no information...

Distribution & Pricing
Dartaine Phifer
BA181 Foundations of Marketing
Instructor: Bell, Faith
A manager’s job is never ending, if you want to be successful in this business. Denny McKnight stated, “We think of best practices as doing all the right things with the right tools and getting the right results” (Harps, Best Practices in Todays Distribution). One of the marketing plans, distribution plays a key role to how products are exposed, stored and delivered, another key factor is the price of the products. Satisfying the customer making a product available either using direct or indirect means makes the difference when it comes to profit. Managing a restaurant, finding new ideas to expand this business as a whole, but more of a trademark, a name to be known by anyone and everyone. Distribution is very important, even for a small family own restaurant, choosing the best method can determine the success or failure of the business. Selling our own salsa homemade allows us to save or spending and gaining more in profits. Networking with companies and partnering with stores for shipping of products used to make the salsa since we started to grow our own vegetables to stay fresh. Buying another freezer storage to store our very own product right here at the restaurant. We choose not to buy or use a warehouse, only if we expanded and went stateside into selling the salsa, we decide to stay local. We contracted...

1. What were the major problems that were affecting the relationship between the company and the distributors?
Though the Office Equipment Division had a strong and committed distributor network Morgan imposed numerous conditions on the distributor’s operations. Initially since being Morgan’s dealer was considered an honour they agreed to all its conditions but later the dealers were pressurised on many terms which were the main reasons of friction between the dealers and the company. The following were some of the problems that existed between Morgan and its distributors.
Morgan assigned the dealers specific territories and by policy cross-selling was not allowed. They were also not allowed to distribute any other brand of similar products
Officially dealers were not...

...company can identify the different ideas and opinions of the intermediaries. Further, company is also able to take information about the competitors’ strategies. It has been identified that, without communication company cannot be able to influence the customers to buy the products (Kotler, Shalowitz & Stevens, 2011). Prices of the scooter are also high, which needs aggressive marketing in order to generate awareness among the customers. Communication is also helpful in providing every type of information to the customers about the functions of scooters. On the other hand, communication is sometimes ineffective, if the executive do not have to skills to influence the intermediaries. Improper communication channel creates disturbance in the distribution programming model.
Effective Work Teams: Organization has to develop the effective work teams in order give tough competition to the rivalry firms. In addition to this, these work teams will distribute the products to the intermediaries, so that these products will reach to the final customers. Dealerships have strong loyalty to the competitors’ products (Swaim, 2011). Therefore, these effective work teams will identify the strategies of competitors and make healthy relationships with intermediaries. This strategy provides one advantage to the company that cohesive work teams will develop some innovative ideas to produce the scooter at low cost with high fuel efficiency. On the other hand, effective work...

Parasitic Drag/Skin Friction
-------------------------------------------------
-------------------------------------------------
Parasitic drag is drag caused by moving a solid object through a fluid medium (in the case of aerodynamics, more specifically, a gaseous medium). Parasitic drag is made up of many components, the most prominent being form drag.Skin friction and interference drag are also major components of parasitic drag.
-------------------------------------------------
In aviation, induced drag tends to be greater at lower speeds because a high angle of attack is required to maintain lift, creating more drag. However, as speed increases the induced drag becomes much less, but parasitic drag increases because the fluid is flowing faster around protruding objects increasing friction or drag. At even higher transonic andsupersonic speeds, wave drag enters the picture. Each of these forms of drag changes in proportion to the others based on speed. The combined overall drag curve therefore shows a minimum at some airspeed - an aircraft flying at this speed will be at or close to its optimal efficiency. Pilots will use this speed to maximize the gliding range in case of an engine failure. However, to maximize the gliding endurance, the aircraft's speed would have to be at the point of minimum power, which occurs at lower speeds...

...4.2 Shapes of Distributions
Learning Goal: To be able to
describe the general shape of a
distribution in terms of its number
of modes, skewness, and
variation.
Number of Modes
One way to describe the shape of a
distribution is by its number of peaks, or
modes.
Uniform distribution—has no mode because
all data values have the same frequency.
Any peak is considered a mode, even if all
peaks do not have the same height.
A distribution with a single peak is called a
single-peaked, or unimodal, distribution.
A distribution with two peaks, even though not
the same size, is a bimodal distribution.
What is the following distribution?
How many modes would you expect for each of the following
distributions? Why? Make a rough sketch with clearly
labeled axes?
The body temperature of 2000 randomly
selected college students
The attendance at Disney World during
a year
The last digit of your phone number
Symmetry or Skewness
A distribution is symmetric if its left half
is a mirror image of its right half.
A symmetric distribution with a single
peak and a bell shape is known as a
normal distribution.
Symmetry or Skewness
A distribution is left-skewed
(or negatively skewed) if the...
