Why is the oral vaccine for polio not given to children suffering from diarrhea?

There are two possible reasons for why the oral polio vaccine ("polio drops") might not be given to children or infants with diarrhea. The first reason would be that this vaccine, like any other, triggers a minor immune response. The purpose of a vaccine is to train the body to recognize and fight off specific infections by introducing a weak or dead form of the virus. After a vaccine, it is common to experience minor...

What are the historical similarities between South Africa and India? Since I am analyzing July’s People and the Miracle of Purun Bhagat, I need...

Great Britain had a direct and large colonial presence in both South Africa and India, and in both cases, the British implemented colonial governments run by white settlers, and subjugated the native populations through brute force and the implementation of caste systems. Britain's colonization of India was somewhat more straightforward and much more massive in scale than its colonization of South Africa, partly because the so-called Cape Colony (which later became South Africa) was first colonized by the Dutch in the late 1640s. Later in the 1680s, the Dutch settlers were joined by German and French Calvinists. Unlike the white English settlers who came to form the enormous colonial government of India (The British Raj), the Europeans who settled in what is now South Africa intermarried with the indigenous population, and the progeny of those matches created what would later become known as the "colored population," under Apartheid Rule. Whereas British rule of the so-ca

Were political cartoons part of the causes of U.S. support for World War I and for World War II?

Political cartoons were a factor in swaying us to join World War I, to support the Allies in World War II before the attack at Pearl Harbor, and to support our war effort once we entered both wars. The media had a big impact on American public opinion. Newspapers were a major source of information for many people in the 1920s and in the 1930s. Many political cartoons showed the Germans in a negative light.... Political cartoons were a factor in swaying us to join World War I, to support the Allies in World War II before the attack at Pearl Harbor, and to support our war effort once we entered both wars. The media had a big impact on American public opinion. Newspapers were a major source of information for many people in the 1920s and in the 1930s. Many political cartoons showed the Germans in a negative light. The cartoons showed how German submarines were killing innocent American people. They showed what the world would be like if the Axis Powers defeated Great Britain prior to 1941

What is the setting in "The Most Dangerous Game"?

The setting is a Caribbean island called Ship-Trap Island, owned by General Zaroff, sometime in the twenties.   The story was written in 1924, and there are references to World War I.  Therefore, the story is probably set sometime in the early twenties.  The story’s action mostly takes place on the mysterious Ship-Trap Island, which has a bad reputation among sailors.  It turns out the reputation is deserved, since there is a man who lives...

In Of Mice and Men, what flaws does Crooks have?

Crooks is a pathetic figure because he is ostracized by the white workers and because he suffers chronic pain from his broken body. It seems inevitable that he would build up some resentment against fate and against humanity, but he cannot show it because he is at the very bottom of the social ladder. He could easily lose his job if anyone took a dislike to him, and he could even lose his life, as... Crooks is a pathetic figure because he is ostracized by the white workers and because he suffers chronic pain from his broken body. It seems inevitable that he would build up some resentment against fate and against humanity, but he cannot show it because he is at the very bottom of the social ladder. He could easily lose his job if anyone took a dislike to him, and he could even lose his life, as Curley's wife intimates when she suggests that she could have him lynched if she accused him of attempting to rape her. This doesn't come out in the dialogue but the reader understands th

What are a few quotes about death in chapter 1 of The Book Thief by Markus Zusak?

"Chapter 1: Arrival on Himmel Street" can be found within the larger “Part One: The Gravedigger’s Handbook.” Because the narrator of our story is the character Death, the entire narration is spoken by him. Even quotations spoken by another character are told to us by Death. The first quote about death in “Chapter 1: Arrival on Himmel Street” is spoken as a part of Death’s narration: A six-year-old boy died in the third carriage. This refers to Liesel’s brother’s death. This moment is one that will haunt Liesel for a long time. Death relates that Liesel is the one holding her brother when he dies and that he died after a “spurt” of coughing. The two children are on their way to live with their foster parents, but Werner “didn’t make it.” The next quotation talks about the finality of this death: Her brother was dead. Liesel Meminger is the titular character. Her brother is Werner Meminger. Death always gives details in an unemotional way, and this quote is no exception. Liesel

Critically discuss the relevance of philosophy and the philosophy of education in a teacher education programme.

There are as many different approaches to teaching students as there are students themselves. As a result, it is important that someone learning to be a teacher also learns about the different philosophies and comes to identify their own. Of course, a teacher's philosophy will (and should) change throughout their career as they come to learn new information and have new experiences, but they should leave their program with an understanding of 1) what they...

How can I formulate three topic questions aimed at analyzing the leadership in Lord of The Flies, with particular attention to Jack?

Topic questions are those that open various avenues of analysis and discussion. Perhaps, in the process of generating topic questions, the student may wish to consider aspects of the characters around whom the questions will revolve. Take, for instance, Ralph and Jack. Even if Jack is to be the primary focus, the student can gain better insight into his character by contrasting him with Ralph, for instance.Questions in this area of discussion could be...

Who influences Macbeth the most in Shakespeare's tragedy Macbeth?

According to renowned Shakespearean critic Harold Bloom, Macbeth is most deeply influenced by his imagination, as he terms the play "a tragedy of the imagination." Because of its numerous murders, this play becomes a virtual tragedy of blood, but Bloom contends it becomes even more horrific because of the "ultimate implications of Macbeth's imagination itself being bloody": The usurper Macbeth moves in a consistent phantasmagoria of blood: blood is the prime constituent of his imagination. He sees that what opposes him is blood in one aspect...and that this opposing force thrusts him into shedding more blood. ( Shakespeare: The Invention of the Human )  Macbeth himself says, "It will have blood, they say: blood will have blood" (Act II, Scene 4, line 128). That is, Macbeth imagines the blood he has shed will return to avenge itself by killing him. Thus, his mind becomes consumed by these horrible imaginings of this continuing battle of blood. This conc

What is one prejudiced quote from the novel To Kill a Mockingbird?

In Chapter 23, Atticus explains to his children that a person related to Walter Cunningham initially voted for Tom's acquittal during the trial, which is why the jury deliberated for so long. Jem and Scout are shocked to hear this, and Atticus continues to elaborate on the Cunninghams' respectable family background. Scout then mentions that as soon as school starts she is going to invite Walter over for dinner. Aunt Alexandra tells Scout, " We'll...

Is Herman Calloway Bud's father?

Despite the fact that Bud believes him to be so for almost the entire duration of the book Bud, Not Buddy , Herman Calloway is not Bud's father. Rather, he is his grandfather.  Bud is under the impression that Calloway is his father because his deceased mother, Angela, left behind several posters showing Calloway with his band, the Dusky Devastators of the Depression.

Banquo says, "The earth has bubbles as the water has, / And these are of them." What is the significance of this quotation?

Banquo speaks these lines immediately after he and Macbeth have been confronted by the Weird Sisters. They have received their respective prophecies, that Macbeth will become Thane of Cawdor and then king, and that Banquo will father a line of kings. However, when Macbeth attempts to ask how it is that the Sisters know this information or why they've shared it, the witches simply, and inexplicably, vanish (according to stage direction).

What is Twain satirizing through the duke and the king?

Examples of satire abound in Mark Twain's  The Adventures of Huckleberry Finn , but perhaps none are as excellent as the duke and the king. Two of my personal favorite characters, the duke and the king are conmen whose actions suggest multiple satirical connotations. For our purposes, I'd like to focus on the fact that, by naming two conmen "the duke" and "the king," Twain satirizes political leaders at large. It quickly becomes clear that...

What are five character traits of Thomas in Gathering Blue?

Thomas the Carver lives in the Council Edifice with Kira. Like Kira, he was orphaned and taken in by the Council of Guardians because of his artistic abilities. Thomas can be described as friendly, conscientious, previously mischievous, helpful, and complacent. Thomas makes Kira feel at home in the Edifice, explaining to her about the tenders and how various things work there. His friendliness makes life at the Edifice happier and more comfortable for Kira.

In the story of "The Pit and the Pendulum" by Edgar Allan Poe, what does the "descent of the soul into Hades" mean?

This quotation occurs at the end of the first paragraph of the story, and it is a simile comparing that which the author is going through to death. In mythology, Hades is the realm of the dead in the afterlife and does not necessarily have any concept of torment or punishment associated with it. However, in Christian tradition, the term "Hades" is the equivalent of hell, a place of eternal suffering where unbelievers go when...

In The Great Gatsby by F. Scott Fitzgerald, what does money symbolize?

In this novel, acquiring money seems to be just about everyone's goal, but it ultimately fails to make even those who have it happy.  Gatsby desperately wants to amass a large fortune to win Daisy's heart back; however, when she learns how he has acquired this fortune, she quickly and selfishly abandons him and returns to her awful husband -- a man whose money is "old" and therefore more valuable, reliable, and indicative of status....

Was the Afghanistan War a just war? How did the leaders justify it to their people and to the international community? What were the aims of this war?

First, we need to get a clear meaning of "Afghanistan War" and "just war."  I am going to assume you mean the U.S.-led invasion of Afghanistan in November 2001 after the attacks of 9/11.  By just war, you mean that the reason for going to war was just and the actions taken during that war were proportional to the attack of 9/11.  I will say "yes" to both counts.  The United States was attacked by...

From To Kill a Mockingbird, what are some passages containing literary elements and themes?

There are a couple of passages that contain literary elements as well as major themes from Lee's  To Kill a Mockingbird.  They are based off of what something Atticus says because he is the major role model in which wisdom resides. Since the story is written from Scout's point of view, too, she tends to get much of her guidance and advice from her father. One of the first pieces of advice she receives is after her first day of school. Things didn't go well with her teacher or among her classmates. Atticus tells his daughter the following: "First of all. . . if you can learn a simple trick, Scout, you'll get along a lot better with all kinds of folks. You never really understand a person until you consider things from his point of view--until you climb into his skin and walk around in it" (30). Atticus uses the visual image and metaphor of climbing into someone else's skin, then walking around in it, to make a point that also becomes a guiding theme in the

In "The Secret Life of Walter Mitty" by James Thurber, why does Walter Mitty choose to daydream?

How long (how many hours) will it take the average high school student to read Bernard Malamud's novel The Natural?

The edition of Bernard Malamud's 1952 novel The Natural  consulted is 249 pages in length. The average novel has between 250 and 300 words per page. The average high school student reads at a pace of 214 to 250 words per minute, the lower end of the scale representing 9th grade students and the upper end seniors. One could, therefore, logically estimate that it will take the average high school student -- assuming, let's say,...

What is the significance of the poem "Nothing Gold Can Stay" in The Outsiders?

In "Nothing Gold Can Stay," Frost suggests that while gold is the most precious of materials, it is so valuable that it cannot "stay," or remain in its pure form because it is subject to theft, alteration, and even damage. Frost's poem relates to Johnny because the gang tries to keep him "pure" and out of trouble, but he becomes caught in conflict and danger.

Why does Jem tremble when he comes back from getting his pants in Harper Lee's To Kill a Mockingbird?

By the end of Chapter 6, Jem trembles because he has experienced a shock retrieving his pants from the barbed wire fence surrounding the Radleys' house. In the beginning of Chapter 7, Jem explains to Scout that his shock stemmed from feeling constantly watched . In Chapter 7, Jem explains to Scout that, when he returned to the Radleys' property to retrieve his pants, he did not find them as he had left them. When his pants caught on the barbed wire fence, Jem had to get them off as quickly as possible and leave them in a tangled heap under the fence. When Jem went back that night to retrieve them, however, he found them "folded across the fence. . . like they were expectin' me." His feeling that someone had expected him to retrieve his pants  makes him tremble that night. Jem continues to explain that, not only had someone folded them neatly and laid them on top of the fence, someone had also sewn up the tear but in a crooked, disorderly fashion. Because Jem f

Was Julius Caesar an astute politician, a military genius, a scheming opportunist, a visionary or a combination of all these ?

Based on the vast amount of research done on Caesar’s life and legacy and the variety of scholarly perspectives that have emerged, it is safe to say that he was an astute politician, a military genius, a scheming opportunist, AND a visionary. Caesar was able to gain much of his initial power because of his familial ties to the prestigious Julian clan. He climbed the political ladder from quaestor, to aedile, to praetor, to provincial... Based on the vast amount of research done on Caesar’s life and legacy and the variety of scholarly perspectives that have emerged, it is safe to say that he was an astute politician, a military genius, a scheming opportunist, AND a visionary. Caesar was able to gain much of his initial power because of his familial ties to the prestigious Julian clan. He climbed the political ladder from quaestor, to aedile, to praetor, to provincial governor, to consul, and eventually to ultimate dictator of Rome. His path to power was remarkably intuitive, which is in

In "Odour of Chrysanthemums," Walter's death touches off a big epiphany for Elizabeth, who suddenly realizes that the life she was living is a big...

When Walter dies in "Odour of Chrysanthemums," Elizabeth realizes in the end that she has shared nothing with her husband. She thinks, "And she knew what a stranger he was to her. In her womb was ice of fear, because of this separate stranger with whom she had been living as one flesh." While she has had two children with her husband and is pregnant with another, she realizes that she has never truly known him. After having this epiphany, Elizabeth will likely go on to lead a more authentic life. She thinks, "She had refused him as himself.—And this had been her life, and his life.—She was grateful to death, which restored the truth. And she knew she was not dead." In other words, she had never accepted her husband for who he was, and she will be more likely to accept others as they really are in the future. However, as she will have three children to raise on her own, she may dedicate herself to that task rather than looking for a relationship. The charac

In Shakespeare's The Merchant of Venice, put yourself in Portia's shoes in Act 3, Scene 2. What will you do and why?

Act 3, Scene 2 of Shakespeare's  The Merchant of Venice is when Bassanio wants to try his luck by choosing from the three caskets for Portia's hand in marriage. Based on the previous suitors who have failed, Portia feels that Bassanio could choose incorrectly and fail just as easily.

In the first five chapters of Bud, Not Buddy, where is Bud's mother mentioned?

Chapter five is your best bet for sentences that are about Bud's mom.  It is also the best chapter to find quotes that are spoken by Bud's mom.  Bud's mom is dead, so chapter five is mainly a flashback.   One of my favorite lines from Bud's mother is the following: She'd tell me, "Especially don't you ever let anyone call you Buddy. I may have some problems, but being stupid isn't one of them....

When Jerome becomes politically lyrical, he is brought back to reality rather rudely. Is there any such instance in the story of Three Men in a Boat?

What are some reasons to have sympathy towards Shylock in The Merchant of Venice?

There are a number of reasons to sympathize with Shylock. For one, he is a Jewish man in the Catholic Venice. In a sense, he is a stranger in his own country. In the play’s conclusion, the Christian Antonio is referred to as a citizen, while Shylock is considered an alien. Shylock does not have the same rights as Christians do.

Jessica’s elopement with the Christian Lorenzo is another reason to pity Shylock. He is distraug

Is there any simple way to separate aluminum from plastic?

A number of simple methods to separate aluminum and plastic can be devised. These depend on the differences in the properties of these two materials. We can use differences in the density and melting points to our advantage.  Differences in density: aluminum has a specific gravity (ratio of density of a substance to that of a standard fluid, typically water) of 2.7. In comparison, depending on the plastic in question, the specific gravity may vary... A number of simple methods to separate aluminum and plastic can be devised.

What are three reasons why many Maycomb citizens do not want to serve on the jury?

In Chapter 23, Jem voices his frustration regarding the Tom Robinson trial. During the conversation, he wonders aloud why Maycomb residents don't sit on juries. Atticus responds that there are three reasons for this. First, he states that most people in Maycomb aren't interested in serving on juries. Second, he states that some Maycomb residents are afraid of the consequences of serving on one. Atticus provides an example to explain the second reason. He states...

How much energy does a pair of 800 W hair straighteners transfer every second?

As I understand, a pair of hair straighteners is one thing, not two. It is marked as 800 W, which indicates their power consumption. W means Watt, a unity of power named after James Watt, a Scottish inventor who made great improvements to a steam engine. By definition, power is the work over time, or the speed of performing work. Also, it may be defined as the speed of using energy. The unit for energy... As I understand, a pair of hair straighteners is one thing, not two. It is marked as 800 W, which indicates their power consumption. W means Watt, a unity of power named after James Watt, a Scottish inventor who made great improvements to a steam engine. By definition, power is the work over time, or the speed of performing work. Also, it may be defined as the speed of using energy. The unit for energy is Joule, named after an English physicist James Joule. Thus a power of 800 W means 800 Joules used during one second. Because a conversion of electric energy into heat energy is perfo

How many muscles are in your body?

Most sources will tell you there are around 639 to 640 muscles throughout the human body.  There are 30 facial muscles alone.  The muscles of the human body are divided into three categories depending on the placement in the body and the job they do for the body.  The first group are the skeletal muscles.  These muscles are voluntary, which means you have control over their movement.  These are the muscles that actually help you...

What is the best way to learn how to improvise sentences in Japanese?

The best way to practice improvising in any language is to have a conversation in that language, especially if your partner is a native speaker of that language. Do you have any classmates, friends, or family who also study or speak Japanese? If so, maybe you could have a conversation together, coming up with challenging questions that encourage you to think of new answers. If there isn't anyone who can speak with you in-person, you...

Do you think children would have any class distinction if they have been let alone by their parents? Justify your answer.

For better or worse, I think that children will make distinctions based on something that could arguably be called class, even if "left alone" by their parents.  Children are products of evolution and environment.  However, "left alone" seems like a rather imprecise term we should look at first.  Children can be left alone on a deserted island, as they are in Golding's Lord of the Flies , but I doubt that is what is meant in this context.  Certainly, very young children are not left alone to this degree most of the time. There is always some adult to watch over them, in the room or nearby.  I am going to assume that this term is meant to be about situations in which parents provide no overt cues to their children to suggest class differences, and really, that is usually the case, I think. But children are astute little observers and learn quite early to notice differences in those around them and to discern attitudes on the part of their parents.  They may not

How does Lyddie respond to her injury in Chapter 13 of Paterson's Lyddie?

The factory where Lyddie works has been speeding up the machines in order to produce more product.  Lyddie is working several looms at the same time, and she has been successful in keeping up.  Unfortunately, the fast pace takes a long term effect on Lyddie, and she's exhausted all of the time.  Due to the pace and her near exhaustion, Lyddie gets hurt while working in Chapter 13.  She takes a shuttle to the head,...

In Chains, what is the discussion at the Tea Water Pump?

In chapter five, Isabel is sent to the Tea Water Pump to get "special" water for the Locktons.  She doesn't know how to get there, so Curzon volunteers to show Isabel the way.  Chapter six then begins with Curzon leading Isabel to the Tea Water Pump.  Curzon moves very quickly, and Isabel can barely keep up.  Curzon eventually slows down once he realizes that Isabel is struggling to stay with him.  Curzon explains that the...

Why does water left in a pot, exposed to sunlight, evaporate?

Evaporation is a surface phenomena and refers to the change of phase of a substance from the liquid to the gas phase. Also remember that sunlight is a part of the electromagnetic radiations generated by the Sun and hence is heat energy (radiation is a form of heat transfer and that is why we feel hot when we stand in the sunlight for too long).  When sunlight falls on the pot of water, the water... Evaporation is a surface phenomena and refers to the change of phase of a substance from the liquid to the gas phase. Also remember that sunlight is a part of the electromagnetic radiations generated by the Sun and hence is heat energy (radiation is a form of heat transfer and that is why we feel hot when we stand in the sunlight for too long).  When sunlight falls on the pot of water, the water molecules at the surface gain some kinetic energy. Once their kinetic energy is enough to overcome the attractive forces of water molecules, they are able to escape from the water phase and move to t

Go Tell It on the Mountain is said to be a semi-biographical account of Baldwin's life. What similarities does the novel have with Baldwin's life?

The troubled relationship between father and son in the text is drawn from Baldwin's actual life, as is the setting for their conflict and interaction. The agon  between Gabriel and John seems to closely resemble that which really existed between Baldwin and his father, especially in its locale in the church. This was the platform and real-life landscape where a struggle for identity took place. Baldwin performed the role of a preacher as a young man and the church was a major part of his young life. The depiction of Baldwin's time spent in the church in  Go Tell It on the Mountain is thus factual and autobiographical.  The novel's depiction of Baldwin's father very closely resembles the version of his father that Baldwin draws in the essay, "Notes of a Native Son." Elsewhere in Baldwin's fiction, the father figure is similarly characterized as a stern man with little ability or willingness to yield affection to his eldest son. A preacher and a man of def

Why did the United States retreat in the Vietnam War instead of staying back to fight with South Vietnam? I feel like if the United States had...

There are several reasons the United States abandoned the war in South Vietnam in the 1970s, most of all due to growing opposition in the US, coupled with limited success in prosecuting the war. North Vietnam and their Viet Cong allies in the South showed great resolve in the defense of their county in the face of massive American involvement in the way of troops, air and naval power, and military materiel. Vietnamese partisans had initiated opposition to their colonial overlords,...
