Asthma
Breathing is a vital process for every human. Normal breathing is practically effortless for most people, but those with asthma face a great challenge. During an asthma attack, breathing is hampered, making it difficult or even impossible for air to flow through the lungs. Asthma is an increasingly common problem, and has become the most common chronic childhood disease. At least 17 million Americans suffer from it(1), and although it can be fatal, it is usually not that severe(4). There is no cure for asthma, but with proper care, it can usually be controlled.
As someone with Exercise Induced Asthma, I have personal experience with the topic. I have experienced most of the symptoms described in my research, tried many of the medicines, and have my asthma under control. This essay will first discuss the normal function of the lungs, and then proceed to explain how this is effected by asthma. The causes of the disease and the ways of controlling it will follow.
Normal breathing is controlled by the lungs and the chest cavity. Airways are tubes with muscle that contracts and relaxes wrapped around them, and this accounts for the motion of the chest that is associated with breathing. The diaphragm, which is located underneath the rib cage, along with the intercostal muscles, or those in between the ribs, control the movement of the chest cavity(6). When these muscles contract, the chest expands, which lowers the pressure inside the lungs. Since air moves naturally from high to low pressure, the lungs are automatically inflated. In order to exhale, the diaphragm and the intercostal muscles relax, causing the chest cavity to become smaller. The decrease in volume causes the pressure in the lungs to go...

In the novella Maggie: A Girl of the Streets and Other Short Fiction by Stephen Crane, Crane tells a story about Maggie, a girl who lives in the slums of New York City in the 1800s with her family and friends. In novella it is portrayed that Maggie desperately tries to escape the slums, however, because of Maggie’s environment and social forces, it ultimately led to her downfall and demise within society.
In both ways, Main characters Hamlet and Roger Ebert are similar yet different from each other. Both have faced many tragic events in life but each character has come at it differently. In “Roger Ebert: The Essential Man” by Chris Jones, Ebert states “What I am grateful for is the gift of intelligence, and for
In The Scarlet Letter, Nathaniel Hawthorne utilizes imagery to convey that Dimmesdale can represent Puritan Society rather than the round character that can be seen on the surface level. This is seen through the imagery and symbolism of hypocrisy, Dimmesdale as a Christ figure, and the scarlet letter.
Stephen Crane’s novella, “Maggie: A Girl of the Streets” deals with many difficult concepts and situations. However, the most prevalent seems to be the people that find themselves caught in a vicious cycle of violence. Although some claim that a literary label cannot possibly contain Crane’s work, his ideas certainly have much in common with other naturalistic writers of his time. He portrays poor Irish immigrants, the dregs of humanity, struggling for survival during the Industrial Revolution. Even while relating terrible events, Crane remains detached in the typical naturalistic style, seeming to view the world as a broad social experiment. As the story opens, we are instantly drawn into a heart-wrenching arena where people behave like animals, tearing each other apart if it will help them to reach the zenith of the food chain. Yet in this cycle of violence, Crane definitively incriminates the environment over every other malevolent influence acting upon his victims; using a theme of violence, a tone lacking in emotion, rich imagery, and strong personification of the environment, Crane fashions a wild Darwinian view of society that leaves all of the blame resting on a person’s surroundings rather than his choices.
Proactive management of the decision-making process can minimize the threat of groupthink compromising the quality of decisions. Managers can place importance of having a wide variety of options and idea brought to the table. Encouraging employees to thoroughly analyze all aspects of the options, from the moral and ethical implications, to the response they can expect from their opposition. With each decision appoint one or more group member to play devil’s advocate to the suggested options, ask that person to analyze and make a case against each of the suggestions (Sims & Sauser, 2013). Rotate this position throughout the group so that one person is not refuting the groups ideas consistently. Continually encouraging and rewarding contrasting views can hedge the complacency groups fall into after working together for periods of time. Management should be active listeners in the decision-making process being careful to not assert their preference towards a certain option to avoid the group conforming to the preferences of their superiors before the options are fully analyzed (Rose, 2011). Finally, after a decision has been made and the analysis has been completed before implementing or going public with the idea reconvene and go through the choose plan of action one last time to ensure that new information has not become available and
Hawthorne in his early college years extensively read gothic romances and even classic literature. In studying these works they leaked into his works especially one of his most popular The Scarlet Letter. He decided to write historical fiction and romances, which all took place in New England’s past (Bloom 14). Hawthorne mixing gothic romances, writing historical fiction, and using the puritan time was the product of The Scarlet Letter. In the puritans time, everything was God and about God. In Nathaniel Hawthorne’s The Scarlet Letter he uses an abundant amount of symbolism of the forest and the settlement.
The overall commonness of exercise induced asthma seems to be increasing. It is being diagnosed similarly in children as well as adults at rates that are as low as 4% and as high as 20% of the general population.3,4,5 Added to that is the fact that it is being observed that athletes, especially elite athletes, have a much higher rate of exercise induced asthma occurrences. These numbers show that this group of people who experience exercise induced asthma is between 11% and 50% of the general population.5 And in addition to these findings, the number of people who are diagnosed with asthma who also experience exercise induced asthma are reported to be between 50% and 100% in some studies.3,4
Authors utilize symbols as an important literary device. They contribute to the reader’s understanding of the piece and aid in both plot and character development. A well-written novel includes many symbols that enhance the writing and create a deeper understanding for the reader. In the Scarlet Letter, Hawthorne tells the story of an adulterous woman named Hester. Both Hester and her bastard child, Pearl, are continuously persecuted for Hester’s sinful act. Because of her sin, Hester remains an outcast in the Puritan society. Hawthorne utilizes many aspects of nature to contrast Hester to the harsh expectations of the Puritan society.

Asthma is a heterogeneous chronic disease sited on chromosome 5 (5q31). [1, 2] There are about 100 genes linked to asthma. These genes handle the immune system and inflammation [3]. One gene known as DENND1B, causes an increased amount of the molecule cytokine to be released. [4] Cytokine is the motive for the symptoms of asthma to arise. Asthma is affected by several genetic and environmental factors that can cause life-threatening complications to occur for the people who have this disease.
Most of you may not think of asthma as a killer disease, yet more that 5,000 Americans die of asthma each year. According to the Mayo Clinic web page, asthma also accounts for more that 400,000 hospital discharges annually. As the number of people with asthma increases, the more likely you are to come in contact with a person who has the disease. As far as I can remember, I have had asthma my whole life. My mother and one of my sisters also have asthma, so I have a first hand experience with it. This morning, I will discuss some interesting facts about asthma, I will specifically focus on what it is, warning signs, symptoms, causes, and the treatments that are used.
Particularly, two members within my group began to emerge as leaders due to their knowledge, skills, as well as experience working with our chosen population. Although I always view them as ‘experts’ in this topic, our group became less focused on our goals and more concerned about the ‘power struggle’ between our two leaders, before we could reach any consensus. Essentially, our group had two authoritarians butting heads and trying to take lead throughout the beginning of the group process. Thus, the other members or ‘followers’ contribution, like mine, seem to not matter unless they adhered to either leaders’ opinions without question. According to Stringer (2014), “Leadership… Is defined according to its function of facilitating organizational and operational processes, rather than defining and controlling them” (p. 31). The researcher further states that active participation is the key to encourage and motivate group members to invest their time and energy to shape the quality of the group's production. Therefore, our group needed to find ways for all members to have a chance to participate fully and apply their individual strengths, in order to enhance our group’s
The concept of leadership arises out of the need for cooperative action by human beings to achieve certain goals. Leadership seeks to identify and deploy the groups’ pooled resources to tackle problems in order to achieve set objectives. While human beings are independent and capable of individual action, there are many situations in real life that require dependence on one person or a small group of people who have a broad view of the intervening issues enabling them to direct the actions of the rest of the individuals. The degree of success from this effort is a measure of the leadership skill present within a team.
... of moral sense; just as it exist in the Galapagos Islands of Darwin. Crane inserts isolated statements which serve to reinforce the Darwinian aspects of the novella. There is a zeitgeist of natural history that runs throughout. The matter of fact retelling of dreadful events, such as when Crane writes, “The babe, Tommie, died. He went away in an insignificant coffin, his small waxen hand clutching a flower that the girl, Maggie, had stolen from an Italian, she and Jimmie lived.” helps illuminate this point. The first example of Naturalist literature, this novella is original in its approach to literary theory; it is not overly explicit nor does it call for change or revolution in a Marxist fashion, it is unadorned and free of opinion. Maggie: Girl a Girl of the Streets solely recounts what is observable and the rules that are known to be true in the natural world.
Asthma incidence has risen steadily over the past 20 years and directly impacts the lives of millions (U.S.EPA, 2013). Currently, there are about 23 million people, including 7 million children affected by asthma (U.S.EPA, 2014). The Centers for Disease Control indicate an asthma prevalence rate of 8.4% in the United States (CDC, 2011). Additionally, asthma accounts for approximately 500,000 hospitalizations annually. It is also the third highest cause of hospitalization among children under 15. As asthma incidence continue to rise, the American Academy of Allergy, Asthma and Immunology (AAAAI) estimate the number of people with asthma to grow more than 100 million by 2025 (U.S.EPA, 2014).
