Homeostasis essays

Homeostasis essays The human bodys ability to maintain a constant environment is essential to its survival. This capability is referred to as homeostasis. Homeostatic mechanisms keep the body near a set point, based on the sensitivity of central nervous system nuclei, which is an ideal value for that particular person. An example of a homeostatic mechanism is a negative feedback mechanism. Any deviation from the set point is made smaller. This mechanism does not prevent variation, it only helps keep the variation near the set point. Many negative-feedback mechanisms have three components; a receptor, a control center and an effector. A receptor monitors the significance of the variable. The control center is where the set point is established. The effector has the ability to change the variable. The set point varies from person to person. The body usually does not maintain its set point exactly but instead it fluctuates and declines around this point bringing forth a normal range of values. When the body undergoes a physical stressor; such as exercise, a secondary set point is established. The Schneider test measures the recovery rate, the rate at which the body moves back to the original set point once a stressor is removed. It determines the recovery limit of the cardiovascular system. It is based on the measurement of heart rate and blood pressure before, during and after exercise, a stressor in this case is standing and moderate exercise. This system was developed by Dr. Schneider after World War I in order to evaluate combat preparedness and overall fitness of American aviators. Exercise: 15 sec.- 88 Score: 16 ...

Philosophical Thought Thesis Example | Topics and Well Written Essays - 2000 words

Philosophical Thought - Thesis Example While explaining my position, discussion will be made with regard to the themes from the different topics, and what their pros and cons are. The saint could be taken as the path for the more spiritual approach towards life and existence. The saint is beholden by the moral and ethical laws by God, or what is divine and ideal, taking steps and journeys in doing and sharing their beliefs for the betterment of others in a world that has been in constant bouts of chaos and other evils. For the saint, God’s existence may be a necessary condition for securing a meaningful life, but it is generally thought that one must additionally relate to God in some relevant way in the epistemological and axiological dimensions (Seachris, â€Å"Meaning of Life: The Analytic Perspective†). Saints can be characterized with many traits that are in relation to the central quality of godliness, such as being humble, kind, generous, compassionate, and selflessness. The hero archetype could be ta ken as a different approach to an individual’s value of existence and life. The first impression of a hero is an individual who is strong and fearless regardless of the odds. The hero archetype usually is the individual who adheres to the rightness of freedom, doing what is noble and just according to their personal beliefs. The hero typology has been portrayed in various ways, either through mythology or romanticism. Typically, the hero is characterized by traits of being free-spirited, courageous, strong-hearted, and a lover of life. Both could be viewed as distinct, but they complement each other very well, both of them having a distinct path for an individual’s walk in existence. This could be seen even in the earliest and twilight days in the age of antiquity. Greek mythology portrays a lot of notable heroes in their stories and legends. The most notable would be that of Hercules, or Heracles in other writings. Hercules may have been portrayed as a son of Zeus, th e king among all the other Greek deities, but he is still a demi-god because he was born from a mortal woman. As legend tells, Hercules had to undergo the Twelve Labors meant for him as an act of redemption of murdering his wife and daughter due to his insanity. While doing all this out of personal reasons, Hercules did assist many of his fellow men, and even deities through his journeys and trials. For the Greeks, Hercules was considered a hero figure because he showed indomitable will and power to persevere in his tasks. The Greek mythological-poetic drama usually portrayed heroes as individuals overwhelmed by their feelings of doing what they see fit. On the other hand, the philosophy of Stoicism had a more different opinion with regard to how one would live. The Stoic philosophy follows a more ascetic role in life. The Stoics believe that once we come to know what we and the world around us are really like, and especially the nature of value, we will be utterly transformed (Balt zly, â€Å"Stoicism†). The Stoics have always strived for temperance and the discipline of self-control from one’s emotions or passions in whatever they commit themselves to. Temperance leads to a mind and soul that has achieved tranquility or harmony with nature, which is the ultimate goal of the Stoics. This appealed well to what the Romans regarded as heroes among their citizenship, such as soldiers, leaders, and

Nursing Scopes of Practice Essay Example | Topics and Well Written Essays - 750 words

Nursing Scopes of Practice - Essay Example "In 1978, Michigan legislature combined all laws regulating health personnel into one statute consolidating the legal framework for nursing in the Michigan Public Health Code, rather than a separate Nurse Practice Act." (Licensed Practical Nurse: Scope of Practice - Michigan, p 1). Significantly, the Michigan Board of Nursing makes use of the various rules governing nursing found in the Occupational Codes and in the Administrative Rules of Nursing and they serve as the guidelines to issue licenses and promote the health, safety and welfare of the public. As some state laws describe the scope of practice succinctly while others go into great detail, there is an important need for clarity of the scope of practice. The scope of practice for the nurses has improved substantially over the years and scope of practice in Michigan is an example of this change. The Occupational Regulation Sections of the Michigan Public Health Code Act 368 of 1978 provides the definition of nursing in Michigan, which serves as the legal scope of practice statement. In Michigan, the RNs are licensed to practice independently within this scope and the nurse practitioner's practice within a scope of practice is defined by their specialty education and training. "The depth of scope of practice is further defined by the knowledge base of the nurse practitioner, the role he/she is in, and the client population within the practice environment. The American Nurses Association has developed two publications to assist nurse practitioners in explaining their scope of p ractice: Scope and Standards of Advanced Practice Registered Nursing and Standards of Clinical Practice and Scope of Practice for the Acute Care Nurse Practitioner." (Nurse Practitioner Frequently Asked Questions). The generic functions applicable to most nurse practitioner roles include: Comprehensive physical examination and health assessment, promotion and maintenance of health, prevention of illness and disability, management of health care during common acute and stable chronic illnesses, assessment of clients that includes analysis, synthesis, and application of nursing theories and modalities, and health counseling and guidance etc. In order to comprehend the nurse practice acts, scope of practice for nursing, and Public Health code etc of Michigan, it is essential to compare it with other states. Thus, nurse practice acts for the state of Texas have distinctive features. The Texas Board of Nursing recognizes that advanced nursing practice is dynamic and it argues that the scope of advanced practice evolves through experience, acquisition of knowledge, evidence-based practice, technology development and changes in the health care delivery system. "Scope of practice is defined as the activities that an individual health care provider performs in the delivery of patient care. Scope of practice reflects the types of patients for whom the advanced practice nurse can care; what procedures/activities the advanced practice nurse can perform; and influences the ability of the advanced practice nurse to seek reimbursement for services provided." (Guidelines for Determining APN Scope of Practice). Various aspects are esse ntial in determining the scope of practice Texas, including advanced practice education in a role and specialty, legal implications, and the scope of practice statements as published by national professional specialty and advanced practice

The Impacts of the Politeness Principle on Foreign Language Term Paper

The Impacts of the Politeness Principle on Foreign Language Acquisition, Geoff Leech - Term Paper Example An example of these words is the word conduct. If the stress is placed on the first syllable, conduct means â€Å"behavior.† But if the stress is placed on the second syllable, the word means â€Å"to carry out.† Plural words also cause difficulty on the part of the learner. It is sometimes very difficult to explain to the learner why some words can be made plural by adding -s and why some cannot. For example, words like monkey can be made plural by adding -s. But the rule cannot be applied to the word money. The teacher should pay attention to these idiosyncracies to help the learner have a clear idea of when and how to use an aspect of the language being studied. As a result, the learner is able to proficiently and efficiently make use of the language and avoid being misunderstood or hurting the feelings of the person he or she is talking to. This is where the politeness principle comes in. The politeness principle which was developed by Geoff Leech is a series of max ims which help explain how politeness operates in conversational exchanges. According to Leech, â€Å" politeness are forms of behavior that establish and maintain comity or the ability of participants in a social interaction to engage in interaction in a friendly social atmosphere(Leech, 2005). Leech uses two terms for referring to two kinds of illocutionary acts. He calls representatives â€Å"assertives† and directives â€Å"impositives† (Leech, 2005). The politeness principle is comprised of six maxims. Each maxim has a sub-maxim which has less importance (Leech, 2005). These are used to show that negative politeness or avoidance of discord is more important than positive politeness or seeking discord. Leech says that not all the maxims are equally important. He also says that speakers may adhere to more than one maxim of politeness at the same time. The Tact Maxim Theoretical Application The first of the maxims is the tact maxim. This maxim aims to minimize cost and maximize benefit to another person (Leech, 2005). Examples of the tact maxim are â€Å"Peel these potatoes†, â€Å" Hand me the newspaper†, and â€Å" Could you possibly answer the phone?†. According to Leech, there are two levels of politeness in the tact maxim. Commands like â€Å"Sit down†, â€Å"Get a cup of water†, and â€Å" Close the door† are considered impolite while requests such as â€Å"Please sit down†, â€Å"Could you kindly get me a glass of water†, and â€Å"Won’t you have another drink† are considered polite. Leech explains that indirect illocutions are more polite because they give the person being addressed to an option of whether or not to obey. Reiter explains in her book Linguistic Politeness in Britain and Uruguay: A Contrastive Study of Requests and Apology that â€Å"politeness is a form of social interaction, a form that mediates between the individual and the social† (Reiter, 2000). She also adds that politeness assumes that each society has its own prescriptive social rules for different cultural contexts (Reiter 2000). Trosborg in her book Interlanguage Pragmatics: Requests, Complaints, and Apologies that â€Å"politeness is a pragmatic mechanism in which a variety of structures work together according to the speaker’s attention to achieving smooth communication† (Trosborg, 1995). that Leech also explains that the more indirect

The films Bladerunner and Fahrenheit 451 :: essays papers

The films â€Å"Bladerunner† and â€Å"Fahrenheit 451† The films â€Å"Bladerunner† and â€Å"Fahrenheit 451† are similar in the way they show emotions in their depictions of distopias. The emotions shown are not normal to us, but are controlled by the government. The inhabitants of these worlds are being persuaded that emotions are bad, unhealthy. However, some do break free from the system. The cases in these movies are not of really living at all, but just of going through the motions of life. The movie â€Å"Bladerunner† was about androids that were made to not have feelings and not to live longer than 4 years. Rachel is a good example of they tried to control emotions. As one of the new model replicants, Rachel was implanted with memories and could recall emotions. What she did not realize was that her memories were really the memories of her maker’s niece. She did not even know she was an android until Decker did the test on her. She was very upset when she realized that he was right, because she did not know what feelings were real and what feelings belonged to someone else. She worked with the man that created androids, the owner of the Tyrell Corporation, which makes her more upset that she did not know. This is when she exclaims to Decker, â€Å"I am not in the business, I AM the business.† Although she though she was living a normal human life, Rachel was going through the motions of everything humans do, but she did not have real feelings or even her own memories. Therefore, she was not even being her own self. Another aspect of the movie â€Å"Bladerunner† is of those that broke away from the system. The â€Å"Nexus 6† were androids that developed emotions and escaped from slavery, because they wanted to live longer. Roy and Priss are good examples of androids showing that they have emotions. They were manipulative, passionate for what they wanted, and even had loving sides. Roy was the leader of the â€Å"Nexus 6† and Priss was his girlfriend . Priss acted like a helpless girl to get J.F. Sebastian to let her into his house, into which she later let Roy. They made J.F. show them to the owner of the Tyrell Corporation’s house, so they could fight to get an extension on their lives.

The Angel – Ted Hughes Poem Analysis

1) What is the poem about? My personal view is that Ted Hughes has attempted to interpret his inner feelings relating to the deaths of his two wives and mother in his writing. The poem is centred around Halifax and I think this is of relevance because Ted Hughes grew up in the town so will always be able to make a connection between the actual place, his family and his upbringing. I find it significant that Hughes was frequently accused of writing poetry which is unnecessarily violent as my opinion is that he was simply being a typically blunt Yorkshire man, describing visions as he sees them. I am aware that the understandings of meanings may vary from reader to reader, but from studying the poem I understand that Hughes is describing a vision of what he thought to be an angel over the Calder Valley landscape. I also think that Hughes may use his poetry as a method to display his emotions and guilt felt towards both of his wives committing suicide. Also you can read Analysis July at the Multiplex 2) How does the poet use language to convey the meaning, give examples of use of any figurative or metaphorical language? Hughes endeavours to use his poetry as a powerful way of reaching our feelings and emotions in a subconscious manner. In his position as a writer, Hughes attempts to help release our suppressed creative energies, and he believes that poetry is particularly effective for this purpose. Hughes technique involves using appropriate wording to influence the reader's imagination which results in the effect being a release of emotional energy. I don't think his language and structure of writing is necessarily easy to understand. My approach to this was to study the background of Hughes as a person, this helped me to appreciate his work and recognize the style in which Hughes aspires to create a vision. I have researched more of Hughes poetry and upon doing so, noticed and become aware of the fact that certain images recur in his work. In his poem The Angel, Hughes uses metaphors such as â€Å"it was a swan the size of a city!† this type of wording will attract the reader's attention with an element of surprise as a metaphor is a phrase or figure of speech in which a word or phrase that ordinarily designates one thing, is used to designate another. The result is it makes an implicit comparison. â€Å"Smoking Snow† is an oxymoron as two contradictory terms are combined. Realistically, it is not possible for snow to smoke but this is designed to add effect as it sounds quite dramatic. â€Å"Rippling its fringed edges† – Rippling is an onomatopoeia as is fluttered. Hughes uses these types of words to imitate the sounds associated with the objects or actions they refer to (such as fluttered referring to dress). â€Å"Glowed like the night-cloud over Sheffield† would be classed as a simile as it is making a comparison and using the word like. I find the wording â€Å"Strange square of Satin† to be alliteration as Hughes is repeating the consonants to result in the same types of sounds. My view is that Hughes has used the word â€Å"enigmatic† as a personification as it is giving a human attribute to an inanimate object (square of satin). 3) What senses is the poet using to convey his vision and meaning? I think Hughes mainly tries to illustrate his poem The Angel as a vision in which we can receive a vivid and quite clear picture in our heads of the events and images. I think this is particularly correct of the sentence â€Å"She was cast in burning metal† as I can actually envisage the sight of the angel surrounded by the hot, flaming metal. Part of Hughes piece also appeal to my touch senses such as â€Å"When I next saw that strange square of satin I reached out and touched it†. This comment made me think of the soft and silky feel of holding satin in my hand. When Hughes is quoting his vision of the words of advice spoken by his mother it appeals to the senses of sound. Read also  Case 302 July in Multiplex 4) Which pieces of the poem do you especially like and why? The first reason I favour the poem is because I am familiar with the towns he is referring to (Halifax and Sheffield) and I think it is important to comprehend the significance of his Yorkshire origins in order to understand his work. I am curious of the fact that there is often a darker side to Hughes poetry. I particularly enjoyed the section where Hughes was describing his vision of an angel and how it suddenly changed into an omen surrounded by burning metal as I receive a clear picture of the event in my imagination and I can almost feel the terror and panic that Hughes aspires to describe. I like the way that Hughes describes his experiences realistically and does not try to express himself in the traditional and romantic way for which other English poets are famous. I especially favoured The Angel as it arouses strong emotions and it is not a conventional piece. I have noticed that Hughes frequently does not conform to the conventions which society expects of him, and naturally this upsets people.

The Bloody Babe And The Collapse Of Order - 977 Words

The Bloody Babe and the Collapse of Order in Macbeth One of the pervasive motifs in Shakespeare’s Macbeth is the bloody babe. Three major examples of the bloody babe are Lady Macbeth’s imaginary child, Duncan, who looks like a â€Å"naked new-born babe† and the apparition from the witch’s cauldron. These images have abundant symbolic meanings and help construct the chaotic world in Macbeth by showing the collapse of familial order, hierarchical order and time, . The world in Macbeth is not fit for innocent children. It is a world of bloody babes that are harmed by evil acts. The first bloody child shows the collapse of familial order in Macbeth’s household. Lady Macbeth takes on more masculinity than Macbeth in the murder of Duncan. After Duncan has gone to sleep, Macbeth panicked and wanted to quit the business. Lady Macbeth gave the unsettling yet powerful speech to entice Macbeth: I have given suck, and know How tender ‘tis to love the babe that milks me; I would, while it was smiling in my face, Have plucked my nipple from his boneless gums And dashed the brains out, had I so sworn As you have done to this. (I.7.54-59) Through this violent speech, Lady Macbeth takes on a violent and masculine role. At first, the babe is depicted as â€Å"smiling† and has â€Å"boneless gums.† It is innocent of the vice in the world and its forthcoming fate, and vulnerable to any external harm. It â€Å"symbolizes pity, and the necessity for pity.† (Muir 235) It depends totally on its mother.
