Examples of barriers of communication

According to the Business Dictionary, barriers of communication are obstacles in the workplace that prevent the effective exchange of thoughts and ideas.  These barriers can include:  status differences, gender differences, cultural differences, racial and ethic differences, prejudices, and the work environment.

Status differences, especially with regard to the interaction between subordinates and superiors, can create a barrier to communication by making and employee feel intimidated and hesitate to share his or her opinions and ideas.  Furthermore, superiors often fail to ask for these opinions and ideas not realizing the value that they may have.

Different types of biases can present a barrier to communication.  They often dictate the way one interprets a message as well as one's willingness to communicate with those toward whom they are biased.

The work environment can also create a barrier to communication.  Employees and supervisors may not be situated where they can easily interact with each other.  In addition, certain job functions can get in the way of effective communication.

What was the American reaction to President Roosevelt securing of the canal zone?

American reaction to President Roosevelt securing the Panama Canal Zone was quite positive. The United States was in an imperialistic mood in the early 1900s. The United States wanted to spread its influence worldwide in the late 1890s and early 1900s. We had just gained Puerto Rico, Guam, and the Philippines after the Spanish-American War. We were also interested in building a canal in Central America.

The United States wanted to be the country that built the Panama Canal. People from other countries had tried to do this, but they weren’t successful. We offered Columbia $10 million for the land to build the canal, plus a yearly rent of $250,000. When Columbia refused this offer, we supported a rebellion in Panama against Columbia. When Columbia tried to end the rebellion, our military wouldn’t allow them to end the rebellion. We quickly recognized the independence of Panama and offered them the same deal with Panama that Columbia had refused. The Panamanian government accepted the offer. By building the Panama Canal, we could significantly shorten the time it took to travel from the Atlantic Ocean to the Pacific Ocean. It also showed American ingenuity at work.

Since the building of the Panama Canal helped reinforce the idea that our country was a world power as well as showing the capability of American business, industry, technology, medicine, and creativity, many Americans were very supportive of our effort to secure the Panama Canal Zone as well as our building of the Panama Canal.

Who is the best character in the story "The Last Leaf," and why?

There are only three main characters in "The Last Leaf." Johnsy is either listless or asleep most of the time, so she cannot be considered the best character. Sue and Old Behrman are both good characters, and it is interesting that O. Henry made them such strong contrasting types in so many ways. Behrman is an old man, Sue is a young woman. She is a native-born American, he speaks broken English with a thick German accent. Of the two, Behrman seems to be the most unique and complex character. O. Henry had to introduce a painter who liked the two girls, but the author did not want to jeopardize his surprise ending. He misleads the reader by bringing the German painter into the story because Sue needs him for a model; and O. Henry has Behrman express his contempt for the notion that Johnsy could die simply because she identifies with the last ivy leaf on the nearby vine.

“Vass!” he cried. “Is dere people in de world mit der foolishness to die because leafs dey drop off from a confounded vine? I haf not heard of such a thing. No, I will not bose as a model for your fool hermit-dunderhead. Vy do you allow dot silly pusiness to come in der prain of her? Ach, dot poor leetle Miss Yohnsy.”

The dialect and broken English make it a little hard to understand Berhman's thoughts and feelings. This is an advantage to the author because it makes it easier for him to mislead the reader about the old man's intentions.

Behrman is the best character because he is more complex than the two girls. He is much older and experienced. He has accepted his failure. He drinks to excess. He pretends to despise fantasies and feelings, and yet he sacrifices his life because of his feelings for both Sue and Johnsy. He is a failure as an artist, and yet he creates a masterpiece when he climbs the tall, steep ladder in the icy weather and paints a single leaf on the well as a gift which imparts his courage to the sick girl who has been watching and waiting for it to fall.

if DNA sequence is GATTCGAATCGATTAG, what is the mRNA sequence?

When mRNA transcribes DNA, it follows base pairing rules as follows:

If DNA contains Thymine, the mRNA complement is Adenine. If DNA contains Adenine, the mRNA complement is Uracil. This is because RNA doesn't have the base thymine as found in DNA. If DNA contains cytosine, the mRNA complement is guanine. Finally, if DNA contains the base guanine, the mRNA complement is cytosine.

With those rules in mind, if the original DNA template is:

the mRNA template is:        C U A A G C  U U A G C U A A U C

Remember follow the base pairing rules when you need to show the mRNA transcript, produced from the DNA blueprint.

In the Lord of the Flies, how do the "painted faces" liberate the boys?

The "painted faces" liberate the boys by allowing them to engage in savage behavior without feeling self-conscious or guilty about their actions. Initially, Jack paints his face to blend in with the environment in order to camouflage himself while hunting pigs. In Chapter 4, Jack uses white and red clay, along with charcoal, to paint his face. Golding describes Jack's reaction after he looks at his reflection in the water and writes,

"He looked in astonishment, no longer at himself but as an awesome stranger...He began to dance and his laughter became bloodthirsty snarling. He capered toward Bill, and the mask was a thing of its own, behind which Jack hid, liberated from shame and self-consciousness." (Golding 64)

The face paint allows Jack to let his inner beast loose without feeling ashamed. The other boys follow suit and descend further into barbarism. Face paint is described as a mask. A mask covers the identity of the individual wearing it, essentially altering their physical appearance. However, in the novel, this change in external appearance is paralleled internally. As the boys begin to paint themselves, they lower their inhibitions, and become increasingly savage.

The boys' face paint correlates with native African warriors who were described as barbarians by early European colonists. This association with barbaric warriors adds to the unnerving imagery surrounding the boys' masks. Golding mentions that the boys were "freed" by paint, which meant they had the liberty to do anything their primitive human instincts desired. Behind the cover of face paint, the boys felt unrestricted.

Later on in the novel, when Ralph and his followers are discussing how they will approach Castle Rock, Eric mentions that the boys will be "painted." Golding writes, "they understood only too well the liberation into savagery that the concealing paint brought." (Golding 172) Golding continually addresses the savage tribe of boys as the "painted group," and Ralph refers to them as "painted fools." (Golding 178) The unrecognizable and unidentifiable boys engage in primitive tribal rituals and oppose Ralph's attempt to solidify a civilized society.

What is a blood culture?

A blood culture is a test that may be ordered by a doctor when it is suspected that someone has an infection caused by either a bacteria or a fungus. The circulatory system is one of the few places in the human body where it is NOT normal to have either bacteria or fungus. Humans live in symbiotic relationships with various types of microbes; many are helpful, or at least not harmful. 

However, the blood stream is one area where bacteria or fungus are potentially very dangerous. When an infection is suspected, a sample of blood is drawn using a needle inserted into a vein. The sample is placed in a culture dish and observed for growth of any foreign microorganisms. All equipment must be kept sterile, in order to ensure that if any bacteria or fungus is found that the only possible origin is from the blood of the patient. If bacteria or fungus is found in the blood, it is referred to as a sepsis, and is a very serious condition. The microbe may be tested further to determine exactly what type it is, and what treatment is required--for example, a speciic antibiotic. Unless treated with the proper drugs a sepsis can be fatal.

Can someone describe the general look of the Finch house from To Kill a Mockingbird using direct quotes?

They live on the main residential street of Maycomb (6). They had a tree house between giant twin chinaberry trees in the back yard (8). There's a dining room that separated from the kitchen by a swinging door (27). They have a front porch and a back porch; the back porch is screened in and latches (38). It has three bedrooms--one each for Jem and Scout and Atticus. There's a carhouse (this a garage) (113). There's a folding cot in the kitchen where Cal sleeps when she stays overnight for any reason (134). There's apparently a "front bedroom" where Aunt Alexandra has her luggage placed when she comes to live (144). Of course, there's a living room with a fireplace and sofa and a chair where Atticus relaxes and reads in the evenings (and where Aunt Alexandra has her missionary society meetings) (149).
