High School Biology Lesson Plan – Properties of Water

Name:|Hailey Griffin| Lesson Plan Title:|Properties of Water| Grade Level: |10| Content Area:|Biology I| Sunshine State Standards or Common Core Standards:|Sunshine State Standards – SC. 912. L. 18. 12 – Discuss the special properties of water that contribute to Earth's suitability as an environment for life: cohesive behavior, ability to moderate temperature, expansion upon freezing, and versatility as a solvent. Behavior Objectives:|(Three parts: Condition, action, and measurement)Given a model of a water molecule, students will identify the oxygen and hydrogen atoms, the partial positive and negative areas of the molecule, and covalent bonds within the molecule. The learner will correctly identify the 4 main properties of water and give examples of each within 1 minute. Materials (including technology):|Students: Textbook, Pencil/Pen, PaperTeacher: Classroom board, markers, computer, Powerpoint presentation, Word processor, multiple copies of worksheets to pass out, Warm up :10 -15 Pennies, 10-15 Eye Droppers, Cups, Water Mini Labs: plastic petri dishes, paper clips, ethanol, water in eye droppers, glass slides, water, red food coloring, capillary tubes, straws, ice cubes, NaCl, salad oil in eye droppers, hot platesClosure: Koosh Ball| Hook/Anticipatory Set/Lead-In:Total Time: 15- 20 minutes|Prior to class, the instructor should gather the following supplies: Pennies, Eye droppers, Cups, Water.As students come into class, they should form groups of 3-4 people and pick up a one penny, one dropper, a small cup of water and return to their seats. They will also need a pencil/pen. Once every group has the proper materials, the instructor will hand out the accompanying worksheet (Appendix A). They should explain that each group is going to count how many drops of water will fit onto the top of a penny. The team with the most drops of water on their penny â€Å"wins†. As one student is dropping the water onto the penny, another should be count ing and recording the results.The other members of the group should be working on the worksheet, consulting their textbook for answers; this worksheet can be completed at home and is not to be turned in. | Procedures:Lecture: ~25 minutesWorksheet: Remaining class timeMini labs – Day 2, 45 minutes. |After the Penny Lab, the teacher should transition into a Powerpoint lecture on the properties of water (Powerpoint attached to lesson plan). The lecture should last for 25 minutes, enough time to get in the necessary information yet short enough to hold students’ attention.The following topics should be covered in the Powerpoint: the physical structure of a water molecule, states of matter, polarity, hydrophobic/hydrophilic substances, high heat capacity, cohesion/adhesion and surface tension, density and solubility. Once lecture is over, students will receive the Properties of Water worksheet (Appendix B) to work on during the rest of class and to complete as homework if n ot finished. This assignment will be due the following class period at the end of class and will be graded. The following class period, the teacher will set up the class into 6 â€Å"centers†.Each center is a mini lab and will focus on a certain property of water, the students should be able to use the knowledge they gained from the previous lesson to effectively answer questions about the properties of water. Each station will have a single worksheet (Appendix C) listing the procedure for the lab and 3-4 questions about the lab and property covered. Students must provide their own paper and copy down the questions and then respond; they can work together but must have their own answers. The work completed during lab time will be turned in a graded on the day of the test. minutes before class is over, the instructor should pass out a study guide and let students know that there will be a test the next class period, topics from both lecture and lab will be covered. | Guided an d Independent Practice: |On day 1, students will work together on the penny lab, and during lecture, students should be paying attention to the teacher. Finally, once the worksheet is handed out, students should be working independently. On day 2, students will be working in groups, rotating between centers; the teacher should be walking around class helping students when needed.On day 3 students will be working independently on the test. | Adaptations for ELL & ESE students|ELL students will have the opportunity to work with partners to receive peer support and help with complex concepts. Extra tutoring is available during lunch and afterschool. Vocabulary lists are available for pick up; students are encouraged to create flash cards to help them learn new vocabulary words. ELL students will also be given extended time to take tests. ESE students will be given extra time to complete assignments and complete tests.Complex directions will be clarified so the student is confident in w hat he/she is supposed to be doing. Students will be allowed to take short breaks during class and tests. | Closure Activity: |â€Å"Whip Around† Students quickly and verbally share one thing they learned in the class during the lesson. Students will pass around a koosh ball (or similar item) and whoever has the ball must give a short description of something they have learned. This could include topics from lecture, lab, or homework and could be an interesting fact, definition or short explanation of a concept.The teacher should be the first participant and will give an example of a good response, for example â€Å"Today I learned that solid water, or ice, forms a lattice structure which causes it to be less dense than liquid water, which makes it float. † This activity will end once everyone has shared their thoughts. If there is ample time and enough willing participants, this activity could also be used for students to gain extra credit points. Students who wanted to talk about additional concepts could earn up to 2 points extra credit towards their test.The previous day’s assignment should be collected. | Assessment/Evaluation:|On the start of the day 3, students will come into class and prepare for their exam. Once everyone is seated quietly the instructor should pass out the test in which students have approximately 40 minutes to complete (ESE and ELL students have more time). Once a student completes the test he/she should read quietly or work on other classwork. The lab assignment from day 2 should also be turned in for grading. | Appendix A Properties of Water: Penny LabTake a Guess: How many drops of water do you think will fit onto a penny? __________ Cohesion, adhesion, and surface tension are attractive forces between molecules and very important properties of water. Cohesion is the ability of water to â€Å"stick† to itself; it is a result of intramolecular forces (intra- inside, so this is adhesion within the molecul e). An example of cohesion is when you over fill a glass with water, the liquid rises above the rim of the glass but does not fall off the side; instead it bubbles up, which is also caused by surface tension.Surface tension is a special type of cohesion; it can be described as the â€Å"skin† on top of water, in the case of the overfilled glass, the surface tension caused the water to stick together and form the bubble over the rim, this property also allows some bugs to walk on water. Adhesion describes water sticking to other materials and is an intermolecular force (between neighboring molecules). Adhesion can be observed in the stem of a vascular plant; water molecules stick to the xylem tissue and â€Å"climb† up the plant. These properties occur because water is a polar molecule.A molecule of water is composed of 2 hydrogen atoms and 1 oxygen atom, because of the relationship shared between these atoms, one side become slightly more positive and the other slightl y more negative. These partial charges are symbolized by the Greek letter delta, or ?. The polarity of water molecules allows water to dissolve polar and charged substances, making water a good solvent. Molecules that are uncharged, such as fats and oils, usually do not dissolve in water and are called hydrophobic. Procedure: 1. Place a dry penny on a flat surface. 2.With the eye dropper, drip one drop of water onto the surface of the penny, one drop at a time. Have one student in your group keep track of the number of drops. 3. Observe the surface of the penny as the water builds up. 4. Once ANY amount of water has spilled over the edge of the penny record your final count of water drops. 5. Clean up your area and return materials to your teacher. Final Count: How many water droplets really fit onto the penny? ___________ Class Average ___________ Reflection: Explain your results in terms of cohesion and surface tension.What do you think would happen if we added soap, a hydrophobic substance, to the water before dropping it onto the penny?

Certainty and Insanity: Hamlet Essay

With no way to be absolutely certain about anything in life, it makes it hard to deliver the justice some may need. In William Shakespeare’s play Hamlet, Prince of Denmark, Hamlet never allows himself to come to an absolute certainty that Claudius killed his father. Whether it was his insanity or his morals, he is unable to take retribution for the murder of his father, which helps drive him insane. By not taking justice into his own hands, Hamlet’s indecision, and his insanity, ultimately leads him to his own death. When Hamlet first meets with the ghost of his father and hears the story of his death, he doesn’t want to believe the ghost outright. Upon finding out that Claudius has killed his father, Hamlet could have simply went to the Kings’ bedroom and slit his throat while he slept. He ignored this opportunity, which allowed his mind to begin questioning his actions. This is the first time Hamlet will delay the killing of Claudius. He begins to slip into insanity, which paralyzes his actions. Hamlet explains that the time for action isn’t right when he is speaking with Horatio the night he first saw the ghost. â€Å"The time is out of joint. O cursed spite, / That ever I was born to set it right† (I. v. 88-89). Hamlet explains that he understands that the situation of seeing the ghost or even the story may not be right, but he feels like he is the person to fix it. This puts a great deal of pressure on Hamlet, which starts the downward spiral of his insanity. Hamlet faces many dilemmas during the course of the play. He has the dilemma of having to come to terms with losing his father. He then has to deal with the anger he has towards his mother for her quick remarriage. Then when Hamlet finds out that his mother’s new husband, his uncle, was the murderer, he isn’t able to deal with any more. With dilemmas keep piling on top of one another, Hamlet has a psychotic break. As Ophelia explains it to her father, My Lord, as I was sewing in my closet, Lord Hamlet, with his doublet all unbraced; No hat upon his head; his stockings fouled, Ungartered, and down-gyved to his ankle; Pale as his shirt; his knees knocking each other; With a look so piteous in purport As if he had been loosed out of hell To speak of horrors, he comes before me. (II, i, 77-84) In this explanation, one begins to understand that Hamlet has been unable to deal with the death of his father, much less the fact that he was murdered by his uncle. The behaviors exhibited by Hamlet are not the actions a normal person would have, especially one of royalty. As Edward Foster explains, â€Å"That Hamlet loses his mental stability is arguable from his behavior toward Ophelia †¦Ã¢â‚¬  (Foster, par 17). A person not suffering from some form of psychosis would have been more put together and rational. Hamlet’s insanity allows him to sink into a reality that isn’t real, â€Å"†¦.results in the development if a sense of unreality in the affected individual† (â€Å"Hamlet†, par 2) While the ghosts’ story shouldn’t have left any doubt in Hamlet’s mind, he is still uncertain that Claudius did commit the act, fearing that the ghost could be the devil in disguise, just trying to make him a murderer. So in a poorly devised plan, Hamlet thinks he knows a way to get absolute certainty that Claudius killed his father. Hamlet’s plan is, â€Å"There is a play tonight before the king. / One scene of it comes near the circumstance / Which I have told thee of my father’s death† (III, ii. 68-70). This plan is used to gauge Claudius’s reaction, so as to tell if he has a guilty conscious or not. This is where Hamlet’s sanity is furthered questioned. If Claudius’s realizes this is Hamlet’s actions, then he can assume Hamlet knows about his terrible deed, and may send for him to be executed. John Alvis agrees by stating, â€Å"†¦Hamlet’s deeds appear ill considered and politically feeble† (par 9). While that does happen later, Hamlet gets the proof he needs, when Claudius stands during the play and exclaims, â€Å"Give me some light, away!† (III, ii, 252) The next time that Hamlet delays in killing Claudius, it is because he finds Claudius kneeling in prayer after the play. Hamlet assumes Claudius is asking repentance for the killing of his father, thus would still get to walk through Heaven’s gate with a pure and clean soul. Hamlet knows that his father wasn’t afforded this luxury by his words in Act 1 when the ghost said, â€Å"†¦ Cut off even in the blossoms of my sin, / †¦/ No reckoning made, but sent to my account / With all my imperfections on my head† (I, v. 76-79). While King Hamlet was robbed of his chance to repent his sins,  young Hamlet would not be so easy to allow Claudius to die after being forgiven of his. â€Å"†¦ he believes that Claudius, killed at prayer, would not be damned to hell.† (â€Å"Hamlet† par 2) Hamlet believes that allowing Claudius to go to heaven would be just as bad as if he murdered his father. Although Claudius’s reaction is enough certainty for almost anyone, the freak out by Claudius still doesn’t satisfy Hamlet. If Hamlet was clear minded, he would be able to see the truth and complete his promise to his father. Hamlet continues to allow doubt to dictate his actions. â€Å"Contagion to this world. Now I could drink hot blood / And do such bitter business as the bitter day / Would quake to look on †¦Ã¢â‚¬  (III, ii, 365-367) The words Hamlet uses do not show the stability that he thinks he has. Hamlet’s insanity plays such a vital role in his delay of justice against Claudius. He is so wound up in his own mind that he has a hard time accepting that he is the reason of his delay. He spends so much time plotting and planning, he can never really convince himself to do the act. He is also stuck in a realm of pity. Poor, poor Hamlet. He shows this in his soliloquy: †¦ Am I a coward? Who calls me â€Å"villain†? Breaks my pate across? Plucks off my beard and blows it in my face? Tweaks me by the nose? Gives me the lie i’ th’ throat? As deep as to the lungs? Who does me this? Ha! ‘Swounds, I should take it, for it cannot be But I am pigeon-livered and lack gall To make the oppression bitter, or ere this I should have fatted all the region kites With this slave’s offal. Bloody, bawdy villain! (II, ii, 547-557) His self-pity blinds him to his task, and allows the pressures of that task to take over, and allows him to sink into insanity a little more. He knows that he should have already taken Claudius’s life, but because his cowardliness, he has failed to do it, and in turn, sinks further in his self-pity. As Hamlet’s madness continues, his delay makes him responsible for the  deaths of so many others. Had he killed Claudius sooner, the life of his mother, Polonius and Ophelia could have been saved. As Alvis explains, â€Å"By his delay Hamlet has contributed to his mother’s death, and by his own imprudent decisions he has made himself responsible for the murder of Polonius, the consequent madness and death of Ophelia†¦Ã¢â‚¬  (par 12). With that weighing on Hamlet’s mind, he would not have been able to return to a state of sanity anyway, as he had such a guilty conscious anyway. Through all of Hamlet’s delay, he finally makes good on his promise of revenge in the final acts of the play. As Foster explains, â€Å"†¦ he strikes his uncle only after he has discovered Claudius’s final scheme to kill him† (Foster, par 17). While Hamlet has delayed his killing of Claudius throughout the entire play, it wasn’t until the very end of the play that he asserts his authority and locks the door upon his mother dying, â€Å"O villainy! Ho, let the door be locked. / Treachery! Seek it out† (V, ii, 313-314). Laertes then explains the plot of Claudius to kill Hamlet, and he forces Claudius to drink his own poison. This is a certain type of justice in its own. Karma, let’s say. In the play Hamlet, many things take place that alert the audience to the instability of Hamlet. Upon losing his father, his mother quickly remarried her late husband’s brother. Hamlet’s father came back as a ghost to tell Hamlet that he was damned to hell because his brother had killed him. He promised his father that he would seek revenge for his death. All of these things mount together and place a heavy burden on Hamlet. As he progressively gets worse, he begins to alienate everyone in his life, feeding them stories and dancing around questions. He denies things he has given to Ophelia, and denies he had ever loved her. The one person who he trusts the most and the only person he allows to be a part of his plan is Horatio. Horatio is the balance for Hamlet. When it appears Hamlet has gone a little too far, Horatio is able to center him and bring him back to this realm of reality. Hamlet has delayed the death of Claudius because of insanity, but also because of his sanity. Wavering between the two, Hamlet never allows himself the chance to accept his duties. He never actually commits the revenge as promised, but the job does get done in the end.

The Breakup of the Eurozone is inevitable within the next five years Essay

The Breakup of the Eurozone is inevitable within the next five years. Discuss - Essay Example Countries in the Euro zone are restrained from pursuing their self- interest by mutually respecting each other’s sovereignty and independence rights. However, Euro zone must adhered to EMU operating principles. Good governance must be practice at all transactions to avoid future crisis2. January 1, 1999 saw the official launch of the Economic and Monitory Union (EMU). On that day, eleven European countries joined the EMU and five more followed suit years later. Now, EMU is comprised of sixteen member European countries. The first to join were Austria, Belgium, Germany, France, Ireland, Italy, Finland, the Netherlands, Portugal, Luxembourg, and Spain. Greece followed in 2001, then Slovenia in 2007 while Cyprus and Malta joined in 2008. The last to join was Slovakia in 2009. EMU countries adopted Euro as a single currency for transaction purposes. The chief reasons that lead to EMU were mainly to stabilize prices, macroeconomic environment, banking system, financial markets as well as increase trade competitiveness and boost flexibility in the member countries3. Before and after the official launch, different people had different views concerning the sustainability of the Euro Zone especially on areas of viability and desirability. Supporters of EMU claimed that commo n currency has the potential to improve trade, attract more foreign direct investment, stabilize wages and enhance business strategies of member countries. On the contrary, they are opponents who predict that Euro zone is heading for a disaster4. They pegged their arguments on the premise that countries in the Euro Zone are diverse and put individual interest forward at the expense of the EMU. There are benefits and costs associated with Economic and Monitory Union. If costs are more than benefits, EMU may not survive in future and if vice versa, union will endure the test of time. The first advantage is that common currency reduces costs

Use Foucault's theory of the disciplinary society to analyse three Essay

Use Foucault's theory of the disciplinary society to analyse three examples of body discipline - Essay Example Foucault considers this physicality -such as pain, hunger, sorrow, joy, etc- a subject of politics and power. The idea, that body is an object that can be subjugated, threatened and tortured by the external forces and power, gives birth to the concept that body’s fear of torture and pain can be manipulated to grow body disciplines in accordance with the social disciplines. In fact, for Foucault, ‘body’ has always been in the center of the attention of any forms of power or authority because body is easily accessible and manageable by controlling its various organic needs, as referring to Foucault’s obsession with the physicality of human being, Peter Erlandson says, â€Å"Foucault stresses that as well as studying the body as a seat of ‘needs and appetites’ and other ‘biological events’ in the social sciences, the politics of the body also needs to be studied† (662-3). This paper will explore how Foucault’s social dis ciplinary theory explains the body disciplines. According to Foucault, discipline as one of the social constructs developed as a response to the increasing demand of the reformists to view the public or social body in power of the state. This concept of â€Å"the power of the public body† necessarily viewed an individual as a body that needs to be disciplined in accordance with the disciplines followed by the collective social body. But Foucault notes that the social body itself is a group of individual bodies that have internalized a set of acknowledged rules and regulations through a number of social disciplinary organizations. According to Holligan, the social institutions functions as â€Å"regimes whose purpose and success is predicated upon making bodies obedient and practically valuable within a particular social formation† (138). An individual that violates the social disciplines is viewed as a physical power or body that lacks the

The Contributions of the FIFA world cup 2010 to the Local Businesses Dissertation

The Contributions of the FIFA world cup 2010 to the Local Businesses in South Africa - Dissertation Example This type of activity is regarded as one of the most fastidious importance to emerging economies and growing commercial countries, such as South Africa. However, comparatively small work has been completed by researchers to reveal the effect of mega-events, such as the football world cup, on informal as well as formal sectors in emerging economies. Known the comparative size as well as strength of the involvement made by informal sector to different economic activities in the developing part of the world, it has been significant to consider â€Å"how an event like the world cup may help shape the entrepreneurial potential of informal and formal sector participants† (Venter et al., 2012, p.449). This paper is aimed at providing a detail analysis of different contributions made by this world cup on the local businesses of the country. FIFA world cup and economy of South Africa: It has been well-established that super-events are most expected to possess a considerable effect on t he business as well as socio-economic development of the host nations and localities. Commanding as well as hosting of mega-events, such as the football world cup, has been a means through which regions compete in respect to attracting as well as retaining greater volume of capital mobility through place improvement. Also with the help of re-imaging as well as regeneration of local businesses of these regions has been realised. Particularly, sport hallmark as well as mega-events, which have been hosted on either as a one-off basis or as regular basis, has been transformed as increasingly important in the contemporary period of globalisation. Some of the most high profile illustrations of these super-events would incorporate the â€Å"Olympic Games, the Rugby and Cricket world cups, and the FIFA soccer world cup†. These events have been provided to create greater level of emphasis on the development of industrial as well as agricultural sector of the developing countries. Sout h Africa being a developing country has also been expected to be greatly helped by the mega-events like the soccer world cup. Several other important works have been discussed by several other researchers regarding the fact that tourism and travel industry of the developing countries of the world (du Plessis and Maennig, 2010, p.2). Key aspects of concern in regard to the hosting of super-events mainly in the developing part of the world relate to process of optimising their effects for economic as well as social development. These issues are also related to the building of greatest level of national identity along with significant volume of foreign policy effects. The distributional as well as allocative benefits of hosting super-events in the developing countries of the world have been scrutinised with many vital observers. These observers have suggested that widespread growth or development benefits cannot be considered as a necessary corollary of the process of hosting of these types of super-events. This is due to the fact that the marginalised groups can be given little benefit (Venter et al., 2012, p.450). Positive contributions in South Africa: Even though potential opportunities for medium as well as large businesses related to the strategy of hosting of super-events has obtained significant amount of academic notice, limited consideration has been intended for the

Health Assessment Research Paper Example | Topics and Well Written Essays - 1250 words

Health Assessment - Research Paper Example Sometimes, the condition is irreversible, and operation is the only resort to solve the problem. Nevertheless, with prompt medical treatment, proper diet and exercise, the disease could be controlled or even cured in time. This paper discusses nursing practices in dealing with patients with plantar fasciitis, a condition common to people who had history of heavy walking and running. The paper details the complaints of the client, subjective and objective data to be collected, rationale for collecting additional data, and health promotion strategies that a nurse can give to the client. The Patient’s Complaint Waking up with painful heel and finding it difficult to walk and climb down the stairs in the morning have become the usual scenarios in the life of Cynthia. At age 35, Cynthia wondered why she developed arthritis. She thought that the pain in her heel was due to arthritis, given the fact that arthritis is common among her father’s relatives. Her father has been suf fering from arthritis for nine years, and he is now 73. Cynthia first felt the pain three years ago when she started working as a freelance writer for several publishing companies. Working at home, she did not go out frequently and only did so when attending meetings, conferences and the like. She submitted write-ups through email, allowing her to stay at home without needing to dress up smartly. That time, Cynthia gained some weight, thus making her quite obese. She did not think of her ailment as permanent; she barely thought that she got the pain from walking as she did her shopping twice monthly. Three years passed and the pain occurred from time to time whenever she went out to do the grocery. Six months ago, she found a new job as a full-time office-based editorial manager. This time around, she has to wear office clothes and use shoes to pair with them. She has been using ballet flats for three months prior to the consultation. Thinking ballet flats look cute and feel comfort able, she bought three pairs of the shoes. Ballet flats are trendy; they are very popular especially among youngsters and are preferred by those who do walking most of the time. These shoes are very colorful and nice to wear because they are usually made of cotton or textile materials so the feet can breath even with long-time wear. The smooth material does not cause blisters unlike leather shoes. Most of all, ballet flats are cheap so one can practically change shoes everyday. Cynthia was attracted to this kind of shoes, not knowing that they could aggravate her condition. When she consulted with an orthopaedist, Cynthia was instructed to undergo x-ray of both feet to find out if bone spurs grew in her heels. The results are positive. Cynthia has inferior calcaneal exostoses or heel spurs on both feet. These results gave the doctor an impression that she has plantar fasciitis. Plantar fasciitis, otherwise known as â€Å"policeman’s heel,† is the painful condition of t he plantar fascia, the connective tissue found on the soul of the foot, usually at the heel part. According to Roxas (2005), the cause of this pain is multifactorial, including excessive mobility, wearing tough shoes, walking or running on hard surfaces, and being overweight. These characteristics of plantar fasciitis determine the additional data required to be collected. Additional Objective and Subjective Data to be Collected Identifying plantar fasciitis is easy in consideration of the

Discuss Oedipus' tragic flaw and its ramifications Research Paper

Discuss Oedipus' tragic flaw and its ramifications - Research Paper Example To escape such a tragedy, he tied the infant’s ankles and commanded a shepherd to leave it to die at Mount Cithaeron. Taking pity on the innocent soul, the shepherd instead brought him to Polybus, king of Corinth and wife Merope. They raised the child as their own and called him Oedipus. Intrigued by questions about his true identity, and with his adopted parents standing firm on the deception that he is their own, Oedipus consulted the oracle of Apollo at Delphi. Oedipus was told that he is fated to take the life of his father and make a wife of his own mother. Horrified of what awaits him in what he thought was his birth land, Oedipus left Corinth, determined never to return. On his journey to Thebes, he came upon Laius and had him killed when a squabble over pride sets in, inadvertently fulfilling part of the prophecy. At the time, Thebes was in state of trepidation on account of a man-eating Sphinx, thus unable to pay enough attention to the death of its king. Oedipus, how ever, brought the Sphinx’s reign of terror to an end by answering its riddle about the phases of human life. Consequently, Oedipus was granted the right to the throne and the hand of Jacosta, widow to Laius and mother to Oedipus, in marriage. They had four children: two sons, Eteocles and Polynices, and two daughters, Antigone and Ismene. The attempt by Oedipus to break away from the fated catastrophe proved meaningless. As a consequence of the serious mischief he inflicted upon his parents, Oedipus was held responsible for a series of unfortunate events that tormented Oedipus himself, his family, and the whole of Thebes. It was such an irreparable damage that can be put right by neither repentance nor punishment. The Plague in Thebes The magnificent reign of Oedipus in the city of Thebes was brought to a standstill when once again a pestilence that spared not a single being came about. The soil from which the people cultivated their live stocks turned barren, and the robust greenery that supplied their daily bread stopped bearing fruits. Worst of all, the women complained of infertility—unable to bequeath their husbands successors to their homes and duties. This was conveyed to Oedipus in appalling agony by a priest of Zeus. â€Å"Meanwhile, the common folk, with wreathed boughs, a blight is in our harvest in the ear, a blight upon the grazing flocks and herds, a blight on wives in travail; and withal armed with his blazing torch the God of Plague hath swooped upon our city emptying the house of Cadmus, and the murky realm of Pluto is full fed with groans and tears† (Sophocles 3). It was revealed by the blind prophet Teiresias that the plague shall not be banished from Thebes until the death of king Lauis is given justice, and the perpetrator was thrown to perish into the fortress of Hades. Oblivious to the fact, Oedipus vowed to his subjects that he would stop at nothing to take vengeance on the man responsible. Typical for a man in his position, Oedipus demonstrated resoluteness to keep his word despite pleas by his wife to do otherwise. This, unfortunately, resulted in another tribulation that broke his heart and tore his soul into pieces. When her brother Creon came back from an inquest to give light to the tragedy that befell the late king, Jocasta had her suspicions

Social contract theory - Essay Example Therefore in a political sense, the State is the representation of the means by which a group of individuals relate to each other out of the common will to live with other human beings in the community. Hegel views the State as the agent of true freedom for the individual. The basis of self consciousness in an individual, according to Hegel, lies not in his active thinking actions but in the active desires existing within the individual which are in negation. Hegel views self consciousness as desire and he believes that self consciousness can exist only through sublation in a referent other. The certainty of self and individual existence may be obtained through the gratification of the individual’s desires, however these are conditioned by the other; certainty exists only through the cancellation of the other, therefore if a cancellation of the desire is to be effected, there must be the other. (Hegel, 1967). Therefore Hegel does not view the individual a splaying a significant role in politics, except as a part of an institution, i.e, the State. The State is the form of inward self-expression of the people in an objective form. The validation of the individual would exist only in the form of recognition attained from others. For example, where individual ownership of property is concerned, such a property would belong to the person only to the extent that it is recognized by others, i.e, by the State. Being thus recognized by others symbolizes the individual’s struggle for recognition. The State in effect represents the subjective will of a collective group of people. Applying Hegel’s views, an individual’s nature is governed by desire and his self consciousness expresses itself in the form of the gratification of desires. However, according to Hegel, such gratification of desires can occur only in the context of some referent other, i.e, individual recognition is dependent upon recognition by others. In

Adult nursing scenario Essay Example | Topics and Well Written Essays - 1000 words

Adult nursing scenario - Essay Example Mrs. Taylor, 68 is admitted with a history of chronic obstructive pulmonary disease (COPD) She is breathless and anxious.She has limited mobility due to a painful left hip.Using the Reflective Cycle of G. Gibbs (1988) I will reflect on the learning and developmental needs identified in the scenario described. The six 'stopping points' provide a helpful personal insight and are followed, in order, throughout this essay.Description: When Mrs. Taylor was admitted in the condition earlier described, I was working with a senior colleague, a ward sister experienced in adult nursing. The patient was in pain, greatly distressed and with some cyanosis.She had been handling her condition at home with the help of oxygen and drug therapy, so her present state indicated that some triggers must have exacerbated the condition.These could be bronchitis, pneumonia, allergy or too many cigarettes.Feelings: I felt a sense of urgency and the need to get medication started to alleviate the symptoms. I fe lt concern for her physical well-being and some frustration that it could be helped 'at once.'When I observed how sister spoke softly and reassuringly to Mrs. Taylor, touching her hand and smoothing her forehead, I felt slightly ashamed.At sister's suggestion, Mrs.Taylor breathed more slowly and her anxiety diminished. I then sat with her, asking how she was feeling, really listening carefully to her responses.I thought how much more difficult this would be with a child or mentally disabled adult,recognising the need for a more psychological approach... These could be bronchitis, pneumonia, allergy or too many cigarettes. NICE Guideline (2004) conclude ' The disease is predominantly caused by smoking and nearly all sufferers are over 35.' 2. The painful left hip was another major cause for concern. We got her settled in bed, nebuliser mask on and bed head raised, promising pain relief for the hip. Feelings: I felt a sense of urgency and the need to get medication started to alleviate the symptoms. I felt concern for her physical well-being and some frustration that it could be helped 'at once.' When I observed how sister spoke softly and reassuringly to Mrs. Taylor, touching her hand and smoothing her forehead, I felt slightly ashamed. At sister's suggestion, Mrs. Taylor breathed more slowly and her anxiety diminished. I then sat with her, asking how she was feeling, really listening carefully to her responses. 'Attending is the act of really focusing on the person who needs help. We need to make ourselves deliberately aware of what the other person is saying and of what he or she is trying to tell us.' Morrison and Burnard (1991) I thought how much more difficult this would be with a child or mentally disabled adult, recognising the need for a more psychological approach, more reassurances and a 'person-focused' nursing style. Adults like Mrs. Taylor appear more able to contribute to their own improvement, being both knowledgeable and aware. I thought that no matter which nursing domain I was involved in, I would recognise that the same requirements of reassurance, administration of medication and accurate record keeping would apply. I would also adhere to the principles of respect for any cultural or social background.

Conflicting Perspectives Essay Example for Free

Conflicting Perspectives Essay Composers are able to evoke in the audience certain reactions to characters or events in their texts by presenting conflicting perspectives on different issues through the manipulation of the language forms and features of their medium, often communicating their own ideas about issues in question, which results in the creation of meaning within their texts. (?). David Guterson in his 1995 novel Snow Falling on Cedars (Snow) and Henry Bean in his 2001 film The Believer (Believer) demonstrate conscious choices made regarding structure and techniques in the construction of their texts in order to represent conflicting perspectives exploring ideas on racial prejudice and hatred and cultural contrasts and thus engage the audience. Composers can examine racial/religious prejudice brought on by war by using form specific techniques to present conflicting perspectives on the same event, designed to incite certain audience responses. Guterson, in Snow, purposely presents conflicting perspectives between Arthur Chambers and Hatsue and other members of the white community on San Piedro, particularly Etta Heine, in order to draw sympathy for the treatment of the Japanese after Pearl Harbour is bombed. Arthur is empathetic towards them, saying in his local paper the San Piedro Review, â€Å"†¦ those of Japanese descent on this island are not responsible for the tragedy at Pearl Harbour. Make no mistake about it.† The high modality language and short, direct sentences used by Guterson highlights Arthur’s deeply-held opinion of the innocence of the Japanese on the island. In support of Arthur’s argument, Hatsue, through the narrative’s non-linear structure, recalls her pain and confusion at the treatment of her people, saying, â€Å"It just isn’t fair – it’s not fair. How could they do this to us, just like that?† The emotive appeal in addition to Arthur’s article triggers audience support of the Japanese community. Guterson, however, also presents the contrasting racial hatred of the white islanders towards the Japanese. Etta Heine justifies the deportation of the Japanese with blunt, monosyllabic sentences – â€Å"They’re Japs†¦ We’re in a war with them. We can’t have spies around.† The use of the derogative term â€Å"Japs† and the distinct differentiation between â€Å"them†, the Japanese, and â€Å"we†, the white people, illustrates her bigoted hatred of the Japanese. Through the conflicting perspectives of Etta against Arthur and Hatsue, Guterson sways the audience to feel for the ill treatment of the Japanese, and shows them his own opinion on the negative effect of racism in wartime on the perceptions and conduct towards certain groups. Conflicting perspectives are established by Bean in Believer between Daniel, a neo-Nazi who is paradoxically a Jew himself, and a number of Holocaust survivors pertaining to the strength of their actions during WWII which aims to convey a pro-Jewish sentiment to audiences. At a sensitivity training session, Danny is enraged at a Jewish man’s lack of action while watching his son being murdered by a Nazi during the Holocaust. Rapidly cutting over-the-shoulder shots between Danny and the Jews indicate their opposing views. A close-up of Danny when he is asked by the Jews what he would have done in the situation shows his contempt and incredulous disbelief of the Jews’ weakness as he replies â€Å"Not what he did. Just stand there and watch?† Bean immediately employs a close-up reaction shot of the female Jew who rebuts with, â€Å"How do you know? You’ve never been tested like he has. Here in his rich, safe, stupid country it is so easy to imagine oneself a hero.† The personal address through 2nd person and the accumulation of adjectives to build a negative image of America strongly opposes Danny’s prejudiced conviction that Jews are pathetic, and also appeals to audiences the idea that religious prejudice towards Jews is unjustified. As Guterson does in Snow, conflicting perspectives are represented by Bean in order to sway his audience to respond negatively to unfounded sentiments of prejudice. Conflicting perspectives between characters can be used by composers to control the way in which an audience perceives them by exploring the cultural clashes that exist in the text as a reflection of societal (or social?) behaviour. In Snow, Guterson presents conflicting perspectives between Kabuo and the jury during his murder trial. In the opening chapter, a vivid description of Kabuo’s posture and expression is given from the jury’s perspective; he is shown as â€Å"proudly upright†¦ rigid†¦ detached.† This initial portrait portrait of Kabuo makes him suspicious not only to the jury but also to the audience, as Hatsue tells Kabuo using a simile that he â€Å"looks like one of Tojo’s soldiers.† However, Guterson, through the novel’s non-linear structure, refutes this perspective by explaining Kabuo’s behaviour to the audience via a flashback. Through his father’s teachings that â€Å"the greater the composure, the more revealed one was†, the audience learns the reason behind Kabuo’s unemotional stance. Third person omniscient allows the audience to sympathise with Kabuo’s emotive explanation that â€Å"he sat upright in the hope that his desperate composure might reflect the shape of his soul.† Guterson, through conflicting perspectives, influences his audience to understand Kabuo and the impact of contrasting cultural values on the perception of an individual. In Believer, Bean likewise shows contrasting opinions between Danny, who cannot fully repress his secret Jewish identity, and his anti-Semitic ‘skinhead’ friends to create audience sympathy for Danny’s inner struggles with the opposing aspects of his identity. When Danny and his friends break into a synagogue, Daniel shows a surprising respect for his religion which clashes with those of the other neo-Nazis. This directly conflicts with Danny’s character established at the film’s opening, when he violently beats up a Jew for no apparent reason. Wearing a brown shirt symbolising the Nazi SA (brown-shirts), Danny’s dark costuming contrasts with the light coloured one of his Jewish victim, highlighting the evil in his nature. Bean, however, challenges the audience’s view of Danny in order to allow them to understand his conflicting identities. In one frame, Danny is in the foreground walking down an aisle, which is juxtaposed with the othe r Nazis vandalising the synagogue. Their loud, raucous whooping contrasts to that of Danny’s respectful silence, highlighting their different treatments of the Jewish culture. When one of the Nazis tears up a Torah, a sacred Jewish text, after much opposition from Danny, a reaction shot of him shows sadness and pain accompanied by melancholy music, underlining Danny’s unspoken deference for Judaism. Bean’s portrayal of conflicting perspectives on Jewish culture incites the audience to respond more sympathetically towards Danny, and to understand that his veneer is a product of cultural differences in his society. The composers in Snow and Believer have effectively utilised techniques within their medium to represent conflicting perspectives about racial or religious prejudice and cultural differences in order to provoke certain audience responses to the characters, events or situations in their story. This includes reactions of sympathy for a certain perspective or disbelief and even dislike of opposing perspectives. In this way, the composers connect to the audience and generate meaning within their texts. In Snow, Hatsue is confined by the traditions of her culture, as shown when her mother Fujiko says to her â€Å"don’t allow living among the hakujin to become living intertwined with them. Your soul will decay†¦ rot and go sour.† The change in language to refer to the Americans as hakujin and the emotive metaphor of Hatsue’s breakdown of purity highlights Fujiko’s dislike of American culture. This

Application of Pinch Technology and Analysis

Application of Pinch Technology and Analysis INTRODUCTION: The term Pinch Technology was introduced by Linnhoff and Vredeveld to represent a new set of thermodynamically based methods that guarantee optimum energy requirements in design of heat exchanger networks. The application of Pinch technology to study industrial process is called Pinch Analysis. Applying first and second Laws of thermodynamics is essential in Pinch Analysis method. The first law of thermodynamics enables us to use the energy equations in order to calculate the enthalpy change in the streams passing through heat exchangers and the second law decides the direction of heat flow because according to second law heat may only flow in the direction from hot to cold regions but there conditions in heat transfer in heat exchanger like: 1) No temperature crossover should be done: since in a heat exchanger, a hot stream cant be cool down below the cold stream inlet temperature nor the cold stream can be heated up above the hot stream temperature. 2) In reality the hot stream can be cooled down to a temperature defined by the temperature approach of the heat exchanger. The temperature approach is the minimum allowable temperature difference (DTmin) in the stream temperature profiles. The temperature level at which DTmin is observed in the process is referred to as pinch point. Pinch Analysis There are 8 steps in pinch analysis which are: Steps of Pinch Analysis Identification of the Hot, Cold and Utility Streams in the Process Thermal Data Extraction for Process Utility Streams Selection of Initial DTmin value Construction of Composite Curves and Grand Composite Curve Estimation of Minimum Energy Cost Targets Estimation of Heat Exchanger Network ( HEN ) Capital Cost Targets Estimation of Optimum DTmin Value by Energy-Capital Trade Off Design of Heat Exchanger Network 1. Identification of the Hot, Cold and Utility Streams in the Process * Hot Streams: Hot streams that are required to be cooled down. * Cold Streams: Cold streams that are required to be heated up. * Utility Streams are used to heat or cool process streams, when heat exchange between process streams is not practical or economic. 2. Thermal Data Extraction for Process Utility Streams For each hot, cold and utility stream identified, the following thermal data is extracted: * Supply temperature (TS oC) : the temperature at which the stream is available. * Target temperature (TT oC) : the temperature the stream must be taken to. * Heat capacity flow rate (CP kW/ oC) : the product of flow rate (m) in kg/sec and specific heat (Cp kJ/kg 0C). CP = m x Cp * Enthalpy Change (dH) associated with a stream passing through the exchanger is given by the First Law of Thermodynamics: First Law energy equation: d H = Q  ± W In a heat exchanger, no mechanical work is being performed: W = 0 (zero) The above equation simplifies to: d H = Q, where Q represents the heat supply or demand associated with the stream. It is given by the relationship: Q= CP x (TS TT). Enthalpy Change, dH = CP x (TS TT) 3. Selection of Initial DTmin value As discussed before and according to second law of thermodynamics no temperature crossover can be done. Thus the temperature of the hot and cold streams at any point in the exchanger must always have a minimum temperature difference (DTmin). In mathematical terms, at any point in the exchanger Hot stream Temp. ( TH ) ( TC ) Cold stream Temp. >= DTmin For a given value of Q, if smaller values of DTmin are chosen, the area requirements rise. If a higher value of DTmin is selected the heat exchange between the exchangers will decrease and the use of utilities will increase. Thus, the selection of DTmin value has an imprtants and significant implications for both capital and energy costs. This table shows a typical DTmin of some industrial processes: No Industrial Sector Experience DTmin Values 1 Oil Refining 20-40 °C 2 Petrochemical 10-20 °C 3 Chemical 10-20 °C 4 Low Temperature Processes 3-5 °C 4. Construction of Composite Curves and Grand Composite Curve * COMPOSITE CURVES: Composite curves consist of temperature (T) enthalpy (H) profiles of heat availability in the process (the hot composite curve) and heat demands in the process (the cold composite curve) together in a graphical representation. To construct the composite curve, a stream with a constant heat capacity (CP) is represented on a T H diagram by a straight line running from stream supply temperature to stream target temperature. When there are a number of hot and cold streams, the construction of hot and cold composite curves simply involves the addition of the enthalpy changes of the streams in the respective temperature intervals. For heat exchange to occur, the hot stream cooling curve must lie above the cold stream-heating curve. This point of minimum temperature difference represents a bottleneck in heat recovery and is commonly referred to as the Pinch which is DTmin. Increasing the DTmin value results in shifting the curves horizontally apart resulting in lower process to process heat exchange and higher utility requirements. In summary, the composite curves provide overall energy targets but do not clearly indicate how much energy must be supplied by different utility levels. The utility mix is determined by the Grand Composite Curve. GRAND COMPOSITE CURVE (GCC): In selecting utilities to be used, determining utility temperatures, and deciding on utility requirements the Composite curve doesnt provide so much information, thats why Grand Composite Curve (GCC) is used. The GCC (Figure 3) shows the variation of heat supply and demand within the process.Using this diagramthe designer canfind which utilities are to be used. The aim is to maximize the use of the cheaper utility levels and minimize the use of the expensive utility levels. Low-pressure steam and cooling water are preferred instead of high-pressure steam and refrigeration, respectively. To construct GCC the information required comes directly from the Problem Table Algorithm. The method involves shifting (along the temperature [Y] axis) of the hot composite curve down by  ½ DTmin and that of cold composite curve up by  ½ DTmin. The vertical axis on the shifted composite curves shows processinterval temperature. In other words, the curves are shifted by subtracting part of the allowable temperature approach from the hot stream temperatures and adding the remaining part of the allowable temperature approach to the cold stream temperatures. The result is a scale based upon process temperature having an allowance for temperature approach (DTmin). The Grand Composite Curve is then constructed from the enthalpy (horizontal) differences between the shifted composite curves at different temperatures. On the GCC, the horizontal distance separating the curve from the vertical axis at the top of the temperature scale shows the overall hot utility consumption of t he process. The utility can be divided into many temperatures. The GCC indicates that we can supply the hot utility over two temperature levels TH1 (HP steam) and TH2 (LP steam). Recall that, when placing utilities in the GCC, intervals, and not actual utility temperatures, should be used. The total minimum hot utility requirement remains the same: QHmin = H1 (HP steam) + H2 (LP steam). Similarly, QCmin = C1 (Refrigerant) +C2 (CW). The points TH2 and TC2 where the H2 and C2 levels touch the grand composite curve are called the Utility Pinches. The shaded green pockets represent the process-to-process heat exchange. 5. Estimation of Minimum Energy Cost Targets Once the DTmin is chosen, minimum hot and cold utility requirements can be evaluated from the composite curves. If the unit cost of each utility is known, the total energy cost can be calculated using the energy equation given below. 6. Estimation of Heat Exchanger Network (HEN) Capital Cost Targets The capital cost of a heat exchanger network is dependent upon three factors: 1. The number of exchangers. 2. The overall network area. 3. The distribution of area between the exchangers. * AREA TARGETING: To calculate the HEN minimum total area Amin ,divide the composite curve into a set of adjoining enthalpy intervals such that within each interval, the hot and cold composite curves do not change slope. The total area of the HEN (Amin) is given by the formula below, where i denotes the ith enthalpy and interval j denotes the jth stream and dTLM denotes LMTD in the ith interval. NUMBER OF UNITS TARGETING: For the minimum number of heat exchanger units (Nmin) required for MER (minimum energy requirement or maximum energy recovery). The minimum number of units (NminMER) is the sum of the targets evaluated both above and below the pinch separately. NminMER=[Nh+Nc+Nu-1]AP +[Nh+Nc+Nu-1]BP Where : Nh = Number of hot streams Nc=Number of cold streams Nu = Number of utility streams AP / BP : Above / Below Pinch HEN TOTAL CAPITAL COST TARGETING: HEN capital cost (CHEN) is the capital cost is annualized using an annualization factor that takes into account interest payments on borrowed capital. The equation used for calculating the total capital cost and exchanger cost law is given below. C($) HEN=[Nmin{a+b(Amin/Nmin)c}]AP +[Nmin{a+b(Amin/Nmin)c}]BP Where a, b, and c are constants in exchanger cost law For the Exchanger Cost Equation shown above, typical values for a carbon steel shell and tube exchanger would be a = 16,000, b = 3,200, and c = 0.7. 7. Estimation of Optimum DTmin Value by Energy-Capital Trade Off To select an optimum DTmin value, plot the total annual cost which is the sum of total annual energy and capital cost versus values of DTmin. After plotting three important key features can be concluede: 1. If DTmin increases, the energy costs will increase but capital costs will decrease. 2. If DTmin decreases,t he energy costs will decrease but capital costs will increase. 3. Theoptimum DTmin is where the total annual cost of energy and capital costs is minimized. 8. Design of Heat Exchanger Network In designing the heat exchanger network it is essential to know which hot stream match which cold stream. Every match brings one stream to it target temperature. As mentioned before the pinch point divides the network into two separate regions, and each region is designed separeatley.When the heat recovery is maximized the remaining thermal needs must be supplied by the utilities. The graphical method of representing flow streams and heat recovery matches is called a grid diagram . All the cold (blue lines) and hot (red line) streams are represented by horizontal lines. The entrance and exit temperatures are shown at either end. The vertical line in the middle represents the pinch temperature. The circles represent heat exchangers. Unconnected circles represent exchangers using utility heating and cooling. To design the network and construct the grid diagram we use the CP Inequality Rule which states that the heat capacity flow-rate (CP) of the stream leaving the pinch needs to be greater than the CP of stream approaching the pinch, or CPout à ¢Ã¢â‚¬ °Ã‚ ¥ CPin So above the pinch: CPhot à ¢Ã¢â‚¬ °Ã‚ ¤ CPcold And Below the pinch: CPhot à ¢Ã¢â‚¬ °Ã‚ ¥ CPcold After making all the possible matches above and under the pinch separately, the two designs are then brought together and usually refined to further minimize the capital cost. After the network has been designed according to the pinch rules, it can be further subjected to energy optimization.

The company has its base in Cupertino, Califonia, having its CEO and founder to be Steve Jobs, the company can beat its chest to having 284 retail locations spreading across 10 different countries. On the1st, of April 1976 Apple was established by Steve Jobs, Steve Wozniak and Ronald Wayne to sell the Apple I personal computer kit. Steve Jobs was said to own 45% of the company, Steve Wozniak with 45% and Wayne with the remaining 10% Apple with time has brought about a significant reputation in the consumer electronic aspect. The users of Apple electronics tend to be fascinated about and loyal to the products and on the other hand those who have no experience with Apples product most times criticize them an being too expensive. On August 15, 1998 Apple released the iMac and was able to cover up its past failures which includes the first Apple portable, which was to wrong looking and bulky and the Newtons, Apple in entering the PDA market. In 2001, after several years of rigorous developments, Apple came up with Mac OS X a universal operating system targeted at both consumers and professionals. The Mac OS X was a different re designs from its previous the Mac OS 9 which could not constrain the power of UNIX while offering a streamlined user experience with a simplified GUI (Graphical User Interface). The iMac line of professional computers combined with the Mac OS X regained Apples profitability coupled with the r elease of the iPod portable digital audio player, later in the year which was just to crown its productions. The historical success of the iPod created a platform for future product, including the best mobile device in history, the iPhone and the Mac Book line of portable computers and the latest release of the iPad on the 27th of January 2010. Introduction This report is based on carrying out a strategic logistic analysis of Apple Inc. with a view to developing opportunities to develop logistic capabilities of Apple Inc. in this cognizance to the swot analysis, five forces analysis and Porters Generic strategy, Apples frame work. Virtually all these strategic models were done from the logistic perspective. This report addressed the main strategic approaches to logistics that can be done by Apple Inc. This report also look into management issues with regards to the implementation of a new logistics strategy especially from the perspective existing capital, technical and human resources. Finally, this research also helped to evaluate trend and the importance of new technology especially with respect to the future logistics strategy of new companies, critically evaluative the strategic significance of new technology developments and business trends on future logistic strategies for Apple Inc. Its Business Apple Inc. success in the IT world is as a result of the wide range of products varieties portfolio and the strength of the Mac OS X technology. Good brand loyalty. Giving a face-lift to desktop and notebook lines. Well known hardware and software products, the iPod, iPhone, Macintosh Computer, Mac operating system, iTunes. Apple Inc. sells a wide range of third-party Macintosh (Mac), iPhone and iPod compatible products, including application software, printers, storage devices, speakers, headphones, and different other accessories and peripherals via its online and retail stores, and digital content and applications through the iTunes Store. Apple Inc. sells to consumer, small and midsized business, education, enterprise, government and creative customers. Swot analysis The Apple SWOT Analysis the source for the top level management and data information. The analysis puts in view the organizations essential business structure and all its activities and gives the update of the revenue lines and strategy. (Data monitor April 2009,page 30) Strengths Apple Inc. major in developing its own software and hardware. iTunes Music store generates more revenue and the iPod which has easy accessibility on the Windows platform. Apple has an alcove audience that gives the organization some deceleration from the direct price competition. Providing a whole new dimension to desktop and computer lines. Its online access technology can be used to promote product awareness and sales. Has more maneuverable low debt ability. Excellent brand loyalty is associated with Apple Inc. Affiliation with Intel computers in 2006 till date. Powerful research and development department. Weaknesses No strong connection between Intel and Microsoft. Weak domination in business sector. Most Apple product has a very short life cycle which causes revenues to focus on the release of new products and services. Having to major its market in the education and publishing not in other markets. Slow turn around on high demand products. Its market is lacking way behind its Major competitor Microsoft. Past communication between the founder and employee which brought about its loss of reputation. Opportunities Large market population which tend to be brand driven. High rate of virus on personal computers to provide a constant market for its anti virus softwares. The ties of apple other companies are weak, Apple can develop good relationship for joint ventures. The high rate of music downloads and Mp3 are increasingly marketable. The sale of computer via the online platform are on the increase. The laptop market growth is increasing so Apple Computers should concentrate on the improvement and development of new models to satisfy the needs of individual customer. Threats Incompatibility with other organizations softwares. Dell, HP, Sony and Toshiba are major competitors facing Apple in the laptop sector. Free download of music and other software is common with other sites which has high impact on sales for online store sales of music and MP3 download. High prices of its product compared to its competitors which make them loose their market. The long lasting recession may impact the sales of the company due to higher prices of the products and services. The launching of the new Microsoft vista windows 7 which is gaining market share. Speedy change in technology is on the increase. The SWOT analysis above gives us a view that Apple Inc. has strengths that it can use to further develop the brand and invariably increasing its market and gaining an edge over its major competitors. Apple is a company with great success, the iPod music player sales increased its second quarter profit to $320in June 2005 same with its Macintosh computers. The iPod allows the company to in viewing other segments to go into. Apples Mac note books also contribute to the Apples high income. The brand name is one of the most popular brand names in the world, which offers good customer views of its products in the customers satisfaction. Early in 2005 Apple made an announcement on the putting an end to its relationship with IBM the supplier of their micro chips and switch to Intel specialists commented on saying it may make them loose their customers confusion. There is weight on the company to pump up the price of its Mp3 and music download from the music industry since most other company make their income from iTunes than selling their compact discs, |Apple has made sales of 22million on sales of its music player the iPod and further sales of 500million on the downloading of songs from its iTunes store. This shows a statistic of 82% of legitimate downloaded music in the US. The development of the iTunes music store to ease users on tracking their music and downloading it, this was made available, and by the use of the USB cable. Software was made in such a way it allows the pausing of music on incoming calls. There is a great deal of new technological strategies alliance opportunity for Apple. another new software is the Podcast which are downloadable media which is done via the internet and plated back on later events that suits the user. It has a free subscription which Apple can make it a paid subscription to generate more income The biggest fear of Apple Inc is the high level of competition in the IT markets. As a successful company the rate of competition is high so the company has to work rigorously on its market research in order to maintain and retain its position in the market The vast popularity of iPod and Apple Mac are on high demand, and will be affected if economies begin to falter and demand falls for their products. The level of close product substitution effect in the innovative and fast moving IT market. There for the iPod and MP3 are in the trend today, but only yesterday it was CD, DAT, and Vinyl. The future technology might be completely different and the music player could be displaced by the Wireless technologies. Five forces analysis The five forces strategic analysis was developed by Michael Porter. The Five forces framework is widely used as a type of industry analysis b (Johnson et al., 2005). The understanding of the way each of the five forces allow organizations have the basic insight in allowing them model the best fit strategies to be successful in their market (Thurlby, 1998). Apple operates in two primary industries: Computing Hardware and Software Delivery of Entertainment and Media Apple has always been under intense competition within the computer, software, and entertainment industries. Figure 1: Five forces analysis for Apple Inc Competitors Apple Inc top competitors include Dell, Microsoft, HP, Alien ware, Gateway, IBM. Strategic positioning Strategic position is aimed at achieving profitability and competitive advantage. Apples strategic position is to offer users the best computing experience by innovating in hardware, software, and Internet offerings. Environmental Analysis of Apple Inc. Apple, Inc operates as a multinational corporation that designs and manufactures consumer electronics and computer software products. The external environment is the institutions and people outside a business organization that affect it; these include national and local government, trade unions, competitors, customers, suppliers, etc. The external environment is one of the contingency factors that has to be taken into account in designing an organization.( Ed. Jonathan Law.) The external environment has three components: the remote macroeconomic environment, the industry environment, and the operating environment within the organization itself. There are key macroeconomic variables that affect Apple: inflation, unemployment, and competition. The first key macroeconomic variable that affects Apple is inflation. Inflation in an economy can be the result of an increase in aggregate demand that is unaccompanied by an increase in aggregate supply. A rise in any component of aggregate demand can bring about inflation. One reason for a sudden, unanticipated rise in aggregate demand can be an unanticipated rise in the supply of money. Inflation can also result from a decrease in aggregate supply that occurs when businesses find that production inputs have risen in price. Such occurs when labor costs and the price of raw materials such as plastics or metals. Decreases in productivity can also have a negative impact on aggregate supply and, therefore, cause a rise in prices. Apple has been in a situation where the aggregate demand for the iPod touch and the iPhone have been really high but the prices for these products it as a reasonable cost to the consumer. Another key macroeconomic variable that affects Apple Inc is unemployment. The unemployment rate is the percentage of people who are not working but who are actively seeking employment. Shifts in labor market that can create unemployment. At any given time the unemployment rates may differ greatly among nations. Two reasons for the difference are Different natural rates of unemployment and Nations may be in different phases of business cycle. McConnell C.R. and Brue S.L. (2004, p. 140). Between 2001 and 2006 the United States unemployment rate was considerably lower than that of Canada. If the unemployment rate is high then that means Apple may have had to lay off a bunch of employees because of the economy. If there arent many employees working at Apple then productivity will go down. Wages are an industry variable that is determined by the unemployment rate. If the economy is bad and Apple had to lay off employees then the wages of the existing employees may not go up for a long period of time or may even go down. The last key macroeconomic variable that affects Apple is gross domestic product (GDP). The gross domestic product (GDP) is a basic measure of a countrys economic performance and is the market value of all final goods and services made within the borders of a nation in a year. It is a fundamental measurement of production and is very often positively correlated with the standard of living. If there is an announcement in the news that there has been an increase in the GDP this will be an indication that the economy is, in all likelihood, in a growth phase. If the GDP number is comparatively weak or declining, this reflects a negative economic environment for the country, indicating a depressed economy. The world economy is depressed and facing a great recession. These facts will lead consumers finding themselves with less disposable income which will eventually cause them not to spend much consumption on luxury products. Apple will be largely influenced by the reluctant consumption ne eds. However, Apple has better positioned itself in the market. The introduction of new iPhone with a relatively cheap price is reflecting a very good sales strategy to accelerate consumption. Apple has successfully sustained a better profit rate in the last three years despite global economy slow down. However, there is no company that can always increase its profit while the national GDP is decreasing. There are many opportunities and challenges that exist for Apple, Inc. A big opportunity that Apple has is they open their stores in a slow, even-handed way to make sure each one is profitable. Other companies that over extended themselves in the boom could have to pull back drastically as their customers are reluctant to spend. That opens opportunities for Apple to negotiate more favorable lease terms in struggling shopping malls. Another opportunity would be that as Apple opens more and more international stores, that sector of Apples business will be less and less affected by financial troubles in the U.S. An ongoing challenge that Apple faces is keeping the price of their products affordable. Apples business plan includes pricing their products so the consumer can afford them. Even with the current recession Apple is still making a high profit from their computers and electronics. Another challenge according to( www.macobserver.com), Apples Mac growth is three times the average P C sales growth, and theyve sold 120 million iPods, burying the competition. Apple has branched out into the mobile phone market gaining even more consumer awareness. As a result, Apple has had to invest heavily in customer service. Some wonder if they can keep up the pace. Implementing a new logistics strategy within an organization Apple has historically taken a far different path than the traditional Windows and Intel combination. Microsoft provides the Windows operating system to separate downstream hardware producers such as Dell. Apple vertically integrated both the operating system software and hardware completely under Apple. A consumer running Microsoft Windows can choose from a myriad of systems based on the Intel processor, while a consumer running Apples OS X must purchase Apple hardware. Apple is adjusting this strategy by migrating their microprocessors from IBM and Motorola PowerPC to Intel. Analysts believe that the Intel-based Macintosh may be able to run Microsoft Windows applications by the end of 2006. (Burrows) In addition to switching processors, Apple positioned their computers as an immediate option for the traditional Microsoft Windows user. With Apple Boot Camp, users may now use Mac OS X or Windows on an Apple computer. (Sutherland).By allowing users to run Windows on an Intel Mac, Apple reduced the switching costs for traditional PC users. Apple may steal away customers that are willing to pay a premium for a system that runs both Windows and Mac OS X. Apple continues to retain a strategic option to license its technology to clone makers such as Dell. Past attempts at licensing Apple technology (to IBM, Gateway, and others) failed on accord of Apples rigid demands. Many technology leaders (such as a 1985 letter by Bill Gates to Apple CEO John Sculley) criticized Apple for keeping a closed architecture. Apple cofounder Steve Wozniak criticizes this strategy, We had the most beautiful operating system, but to get it you had to buy our hardware at twice the price. That was a mistake.Whether Apple would be willing to pursue this reversal of vertical integration is unclear. Although such a move would cannibalize a portion of Apples own hardware sales, it would also provide royalty-based revenue that could approach $1 billion annually. (Burrows) Jobs traditionally sided against licensing Apple technology. He referred to Mac clone producers as leeches and he personally killed Power Computing by terminating their license in 1997. Increasing inventry Despite a weakening economy and a need to meet customer demand, Apple has been able to maintain a fast inventory turnover rate. The Mac and iPhone maker is sitting at five days worth of inventory on any given day, beating Dells seven days worth of inventory, according to data from UBS. Other PC makers are having even more trouble matching Apples inventory efficiency. Lenovo, for example, is averaging 15 days of inventory, and HP is sitting at 32 days. Intel, however, is showing a much slower inventory turnover rate at 89 days, and D-Link is sitting on a staggering 131 days worth of inventory. Apples quick turnover rate may have been due in part to preparing for its just announced iMac, Mac mini and Mac Pro updates. The company released new desktop computer. Models on March 3, and keeping inventory low helped assure that there would be fewer of the previous model machines sitting on store shelves. While maintaining a higher inventory level can help a company cope with sudden increases in demand, it can also show a companys inability to adequately gauge market interest in their products. For now, it looks like Apple is managing inventory better than its competition. (Jeff Gamet) Future logistic strategies for Apple Inc The development of Apples coverage device and Once developed the Apple convergence device will provide a wide range of functions and powerful processing capability that can be applied to the field of medical care to enhance efficiency and modernize the industry. Apple should work with medical device companies and care providers to develop a set of criteria for necessary capabilities for consideration in developing the platform. The device will function as an integral part of an overhauled recordkeeping, care giving, and medical administrative system modernized for the twenty-first century. The device and software it runs will make use of compatible equipment to measure, document, and file measurements, symptoms, and diagnosis in an easily accessible and fully-portable medical files system. The system will help to streamline care giving, administration, and claims filing, by eliminating mountains of paperwork and cumbersome filing systems. Conclusion This research will give the reader an overview of the logistics implementation strategy adopted by Apple Inc and how the organisation can help improve its supply chain network now and in the nearest future.

How Did The Environment Affect The Native American Indians With Particular Reference To The Woodlan :: American America History

How Did The Environment Affect The Native American Indians With Particular Reference To The Woodland Indians? The environment hugely affected the Native American Indians in many different ways. This is because of the way in which the Indians used the environment and the surrounding land. The Indians were very close to nature, and so that meant that any changes in nature would be changes in the Indians. Land The Indians thought of land very differently to the white man. The land was sacred, there was no ownership, and it was created by the great spirit. They could not sell their land to others, whereas the white people could fence off the land which belonged to them, and sell it freely to whoever they wanted. The Europeans didn't think that the Indians were using the land properly, so in their eyes, they were doing a good favour to the earth. To the Indians, the land was more valuable than the money that the white man had brought with him, even though it didn't belong to them. Indians lived all over America, in many different environments including the flatlands, the forests, the mountains, the deserts, the prairies, on the coast, and even in the arctic. All these Environments affected the different Indians in different ways, so that different Indians evolved over time. Religion Religion was a very big part in many Indians life. Almost every part of Indian life is related to religion, the land is sacred, and religion plays a part in what can be done with it, the first Indians had many different religions, and they continued to have religion for the whole of their lives. Dress was affected, many Indians wore special clothes and jewellery of religious importance. Religion often changed family life, the children respected their elders, especially their grandparents, and the Indians believed in divorce and marriage. Education was religious, the boys were taught to hunt, and the girls to treat leather and prepare food. The Indians believed all life to be sacred, but it could be hunted, as long as it was treated with respect, so this affected the way they hunted, and what food they had. Shelter The environment also affected the Indians shelter in many ways. Depending on where they lived, the Indian tribes had different ways of protecting themselves from the elements using the available resources, and different designs for the general climate. For example, the Indians living in the mountainous and semi-desert areas of the south west lived in light twig shacks and log huts, whereas the Inuits of the sub arctic north America built igloos, and the woodland Indians lived in bark covered houses.

Practical Cognition :: essays research papers

Practical Cognition Theories of Knowledge (Karl Marx) In his early years of writing, Karl Marx's ideas were similar to American Pragmatism, especially his ideas about epistemology. He defines truth in a pragmatic fashion and explains cognition in terms of practical needs of the human being. While some of his ideas were not followed to their logical conclusion, nor made sense, the fundamentals of his epistemology contain valuable ideas which can be viewed as furthering pragmatism as a respectable philosophy. His theory of cognition states that cognition is a biological function of the human which is used as a tool for his survival. Marx defines truth in a pragmatic way. The truth value of a judgement is due to the usefulness of accepting or rejecting the judgement. A statement is true if accepting it makes a positive difference or has a helpful influence and it is false if accepting it causes difficulty or dissatisfaction. The meaning of a statement is the practical result of accepting the statement. In general, then, the truth or falsity of a statement is relative, not only to the individual accepting or rejecting the statement, but also to the circumstances in which that person finds himself. Truth is relative, but Marx is not an extreme relativist (no one to be taken seriously is) because there is a constraint to how relative the truth can be; Humans are making the truth judgements, and humans have a common element, viz . their needs, which do not vary greatly between people. Humans are in contact with nature at a fundamental level. The human understanding of nature is a consequence of the fact that nature confronts humans when they try to fulfill their needs. This is the case with any organism, and each species reacts according to the tools of that species. One of the human tools is the intellect, and it works through the cognition of the perception of elements of nature. Cognition occurs as the organizing of sensory data into categories. Without the ability to make generalizations, man would not be able to think. Moreover, the human capacity to think is exactly the same as making abstractions about experience. There is nothing more to descriptions of the world than those abstractions. Details about the world are described only in terms of generalizations, for if there were a word for a specific detail unique to only one event, then that word would be nothing but a name -an abbreviation for the term, the specific detail x , unique to only this one event, y . The assimilation of the external world, which is at first

Physics of Projectile Motion in Computer Games :: physics video game computer

Introduction Physics define the rules by which we live our physical existence. Many of us go about our day to day lives without any true understanding of the Laws which govern how we interact with our surroundings. Physics is our way of making sense of the forces which act upon us and shape the way we accomplish even the most menial of tasks. From walking to driving to playing a game of catch, anyone can see physics in action. A computer game programmer must take a special look at the forces at work around us. The programmers who code flight simulators, first person shooters, and similar games, often need to model their virtual world as closely as possible to our own. In this project we will look at the first person combat simulator called "Tribesâ„ ¢", by Dynamix. We will focus mainly on projectile motion, but we will also discuss the challenges the programmers had in computing ranges for projectiles, friction, and momentum. Also touched on, will be how they succeeded and failed in their efforts. Challenges In Tribesâ„ ¢, the programmers had to create an environment for the players. The challenge is to model our real life Laws of physics as accurately as possible. However, programmers are not physicists and it would take a super computer to accurately model all physics in a real world environment. This environment includes a variable gravity. This was important to game play in that the programmers could now make different worlds for the players to fight in. A planet of different mass will obviously have a different gravity. The following equation shows the horizontal range of a projectile, R = (VÂ ²o / g) * sin(2Ø) (Halliday, et al 60-64). Where R is the range, Vo is the initial velocity, g is gravity, and Ø is the angle the projectile is fired at. It is easy to see from the equation that a change in gravity will affect the total horizontal range achievable by a projectile. An interesting note is that a 45 degree angle will provide the maximum horizontal range for the projecti le, no matter what the force of gravity is. (Assuming gravity does not equal zero). We are neglecting air resistance in our calculations, as did the makers of Tribesâ„ ¢. When the programmers did this however, they got some unexpected, yet fun results. While projectile motion was not affected greatly, a person flying in the game could reach insane speeds, as there was no terminal velocity.

Human Resources Functions at Next Essay

Introduction: Next is one of the UK’s largest fashion and home retailers. Their ongoing success is built upon a passion for the Next brand that is shared by the whole organisation. This involves a commitment to providing excellent product in well run stores and through an attractive Directory. Head Office Located in an award-winning complex near Leicester, their Head Office in Enderby is home to a multi-skilled population. There you’ll find a comprehensive infrastructure including Product, Sales and Marketing, Finance, IT and HR teams. Stores At Next they have over 340 stores spread throughout the United Kingdom and Ireland. Over 20,000 people work in these stores which are heavily supported by their Head Office and a network of warehouses. These stores range from stand-alone units to much larger flagship stores offering the full Next range. Next Directory The Next Directory provides a facility for people to shop from home and has over I million customers and 1,000 employees. The Next Directory customer services call centre is situated at two sites close to Leicester City Centre. Warehouses Next warehouses are among the most modem in Europe and employ around 2,200 people. Located principally in West York and distribute stock to stores and Directory customers right across the United Kingdom and Ireland. E1 * Human Resources Planning: At Next they undertake human resource planning to determine a course of action which helps them to function more efficiently by having the right labour, in the right place, at the right time and cost. This requires accurate forecasting: organisations need to forecast their manpower needs, both in terms of the number of employees needed and the types of skills and qualities required. It is also important for them to monitor and assess the productivity of the existing and available workforce and recognise the impact of technological change on the way in which jobs are carried out. Human resource planning at Next takes place over different time frames, though for simplicity they can consider is two time horizons: there is planning to meet short-term needs and planning to satisfy long-term intentions. Short-term plans are referred to as tactical plans and usually contain precise, detailed, measurable objectives. Short-term planning is carried out at lower levels in an organisation like Next, at middle manager and supervisor levels. Long-term plans are not as detailed or measured as short-term plans. The longer the time horizon of the plan, the less certain managers can be about outcomes. They are usually made at higher levels of management Long-term plans are also known as strategic plans. Next has to plan carefully to ensure they have the right number of suitable employees for their needs. To do this Next need a good understanding of the labour market in the areas where they operate. Next need to be able to consider the effects of the following labour market factors for human resources planning in a business: * Employment trends * Skills shortages * Competition for employees * Availability of labour (internal and external; to the business). HR palnning also involves looking at how labour is organised within the business. You need to understand the need for businesses to take account of a arrange of factors when making decisions about their internal staffing. Such factors include: * Labour turnover (stability index, Wastage rate) * Sickness and accident rates * Age, skills and training * Succession. You need to know how to use statistics to analyse these factors when appropriate. * Recruitment and Selection: Next’s human resource planning team also needs to be able to identify and analyse the factors influencing and shaping the labour markets from which the organisation recruits staff to satisfy its manpower needs. Human resource specialists have to work in Next within these labour markets to acquire sufficient resources to meet the productive needs of the organisation. At Next Head Office you’ll find an environment, where each employee’s personnel contribution is encouraged. They believe strongly that, although qualifications can give you a head start, its initiative and self determination is what makes all the difference. This is why they don’t always insist on degree qualifications. If you can show that you have good experience and great potential in a relevant discipline, you’ll be considered. People do well at Next and seize the opportunities presented to them. This is why they look for motivated graduates with drive, commercial acumen and a passion for fashion. Individuals who will thrive in an open and creative environment where teamwork is valued. It is a fast-paced environment and it can be demanding. But the people that work there at Next take real pride in their work, and it’s their commitment that has made them what they are today. In return, they offer generous rewards and bonuses. For e.g. Staff Shop access and cut price clothing. Not to mention training and development. Businesses such as Next recruit staff for a variety of reasons. The reasons for why and how they recruit staff are: * The growth of the business * Changing job roles withtin the business * Filling vacancies created by resignation, retirement, dismissal * Temperorary staff holidays * Internal promotion The recruitment process can be very costly, in terms of resources devoted to the recruitment process and costs associated with recruiting poorly performing staff, due to the lack of motivation. It is important therefore to accurately select the right candidates for the interview or you could lose the right one before even the first process. Next are often straight to he point and make it very clear about the requirements of the job and about the person they are looking for. The way in which they do this is through: * The preparation of personal specifications and job descriptions * Carefully planning how, where and when to advertise * Identifying the strengths and weaknesses of job applications curriculum vitae and letters of application * Shortlisitng candidates. * Training and Development: To join Next as a Trainee Buyer, you’ll need either a fashion/clothing/textile/design related degree or HND. They prefer relevant retail experience with strong evidence of fashion awareness. For Trainee Merchandisers, you’ll need a business related or numerically biased degree/FIND or relevant retail experience as a Trainee Fabric Technologist or Trainee Garment Technologist, you’ll also need a relevant degree or an HND in textiles, fashion or clothing design. It is important to have these qualifications due to the demanding customers Next have. Computers have become an integral part of modem day life and are becoming increasingly important as teaching and training tools. In the work place and many other educational institutes computers and networks have become commonplace. This allows companies such as Next and educational establishments to utilise many possible computer training and education techniques. Today the use of computer based training and education covers a very broad spectrum of uses. Many companies now use computers in staff training and education. Computers are used as both a resource to present information and as a tool to develop practical expertise in staff. Computers can be used as a resource to present information because of presentation programs such as Microsoft PowerPoint. This presentation package can be used for basic training such as an employee induction; the presentation could give information about the company and what the employees will be doing. Computers can also be used as tools because they can help develop employees practical skills e.g. an employee who would be working with the companies database would probably be trained on a â€Å"dummy database† this would allow the employee to build up practical skills. Among the many benefits of computer-based training the major benefit to an employer is the reduced cost. As they do not have to send people away on courses which mean they don’t have to pay for travel or accommodation. So the investment in a suitable training scheme often pays for itself, as the computers are already available. The only drawback is that the computer based training courses can be impersonal and the employee may have to be a computer literate to do the course. One of the other advantages is that staff can train when they like at there own desks on the computer. The downside to this is that they are being taught by a computer, which cannot explain to the employee what they did wrong when they make a mistake, although some training packages may be able to do this to an extent. The major benefit to the people being trained close to Next is the convenience as they do not have to travel away and can learn in there own time. They can also get immediate feedback on how well they are doing. The only real disadvantage to using computer-based training is the impersonal touch of being taught by a computer. * Performance Management: A need to manage the performance of its employee’s effectively if Next is to remain competitive. This means that they must use effective management control exercised at both individual and organisational level. A range of processes and techniques need to be in place which allow individual employees to know how well they are doing and for managers to be able to monitor how well their subordinates are performing. At Next they monitor their employees whilst they are working. For e.g. they monitor your call with a customer if you are working in the directory and they observe you when you are serving customers on the shop floor. They do this because they wish to maintain the high standards people think they are at and their value in the market would increase.
