Comparing Ulysses Essay Example for Free

Comparing Ulysses Essay Both Ulysses and Macbeth were able to gain power of kingship, but the way they gained the powers are different. In this essay I am going to compare how they regard power, both differently and similarly. I intend to use Heinemann, (1994), version of Macbeth by Shakespeare and the class handout of Ulysses. The main focus of Macbeth will be from Act1 Scene 7, lines 1-28 and Act 2 Scene 1, line 33-61, whilst I will also take account of other related part throughout the play. Since Lord Tennyson and William Shakespeare are from different era in the history, their perspective of the world will be different, therefore I will also mention about Shakespeares and Lord Tennysons different perspective towards power and language they used. Most great writers reflect their attitude to life on their work, so it is important to consider the social and historical background of the Jacobeans- the time when Shakespeare wrote the play, and the Victorian time, when Lord Tennyson was alive. In Victorian times, Britain was a powerful country. There were unlimited opportunities for mainly the upper class people to broaden their knowledge by going to new places and experience the foreign cultures. When Lord Tennyson wrote this poem, he was grieving over his best friends death. By writing this poem he was able to express his emotional feeling as well as to persuade him to let it go. He also had the opportunities to tell people that it is never too late to seek a newer world. For examples, Ulysses new world would be the after life world and Lord Tennysons new world would be the world without his best friend. At the end of Macbeth, the moral we get is that never to cross the line of Divine Order. During Jacobean time, they believed that the duty of the King is chosen by God: They believed that every living organism has an order and it is decided by God, this is call the Divine Order. If one decides to go against the Divine Order, like killing the King to be the monarchy himself then, he had done something that is very morbid during the Jacobeans: going against God. Shakespeare tried show that by the cost of Macbeth have to face after he had murdered the King, one example is that he lost his respects from his courtiers and at the end he was all by himself. Jacobeans were also very superstitious; they believed that witches are evil because they worship demon, so if there was a plague or a natural disaster, they blamed on the witches: they are first put to trials and then was executed, mainly hanged or burned. Because Shakespeare made Macbeth associate with the witches by talking and worse of all trusting them, that made Macbeth evil. Shakespeare did this to please his King, King James, as he was against the supernatural and was able help King James to spread the evilness of the witches through his play. The poem, Ulysses started by a slow rhythm. Lord Tennyson managed this by using the words with long vowels such as, hoard, and sleep, and feed. These words give us the sense of dullness and mundane, which was how Ulysses feels at the beginning. However, as we go further down the poem, the dullness was decrease as he started to talk about his adventurous days.

English Present: Simple And The Present Progressive

English Present: Simple And The Present Progressive Introduction: As a teacher of English to Arabic speaking students I have encountered a number of specific difficulties Arab students have in mastering the English language. In this paper, I would like to focus on a particular grammatical problem they have in the area of verb tenses because, of all the mistakes that my students make, mistakes with verbs and verb tenses impede communication to the greatest degree. The specific problem I will attempt to look at the area of verbs is the problem that Arabic speakers have in using and confusing the present progressive. I will base the evidence for these mistakes on actual writing errors that Arabic students have made. Mistakes such as I am live in Abu Dhabi. come up frequently in my students writing. This paper is basically a contrastive analysis since I feel that the majority of my students problems in this area come from mother tongue interference. However, as will be noted below, this does not mean I rule out other sources of errors such as intralingual errors. The following is the outline of this paper: In the first section of this paper, I will describe the various aspects of the grammatical structure of the present simple and the present progressive in the English language. In the second section of the paper, I will contrast the grammatical structure of the present simple and the present progressive with its Arabic counterparts. I will show how Arabic has structures that vary significantly and radically from their English counterparts. In the third section, I will introduce a number of examples takes from students written work and give an indepth analysis of the possible sources of the errors, mainly with respect to mother tongue interference, but also looking at some possible intralingual sources for these errors as well. Finally, in the last section, I will attempt to suggest a general theoretical approach to dealing with such problems Part One: A grammatical description of the English Present Simple and the Present Progressive: The simple present tense As we already know, the simple present of every verb (with the exception of the verb BE, which I will not be dealing with as a grammatical description since it is not the specific focus of this paper) is identical in every person with the basic unmarked base form of the verb except for the third person forms he, she and it to which we generally add s or es (Quirk 1985, p.98). However, numerous irregularities arise in the spelling and pronunciation of this third person form (Leicester 1998, 12.12)(Thomson 1986, p. 150). Questions are formed by using the auxiliaries do, does, in the present, and did in the past by putting all these before the subject. Negation is formed in the same way using dont (or do not) and doesnt, (or does not) in the present, and didnt (or did not) in the past. These forms go after the subject. In addition, the verb must be changed to the basic form. The simple present is used for statements that are always true, (e.g. The earth revolves around the sun.) (Azar 1989,p.2). The simple present is also used for events, actions or situations which are true in the present period of time and which, for all we know, may continue indefinitely, (e.g. Fatima goes to school at Zayed University.) (Azar 1989, p.2) What we are saying in these expressions is that this is how things stand at the present moment (Huddleston 1984, p.81). A further use of the simple present is for actions that are habitual, things that happen repeatedly, (e.g. We study a lot.) (Alexander 1988, p.163)(Quirke 1985, p.107). Observations and declarations are another use of the present simple, as in the sentence (It says here that there is a new night club opening.)(Alexander 19988, p.163). The present simple can also be used to express the future, especially when we want to express strong certainty, (e.g. When we graduate, we will get jobs.). Swan, Huddleston, Lewis, Thomson and Quirke, et. al. also add eight other functions of the present simple which might come up in other contexts such as: Demonstrations and commentaries (e.g. First, I take a bowl and break two eggs in it, thenà ¢Ã¢â€š ¬Ã‚ ¦..) The structures here comes and there goes, (e.g. here comes your husband.) Promises and oaths (e.g. I promiseà ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦., I swear à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦, He deniesà ¢Ã¢â€š ¬Ã‚ ¦..) Formal correspondence (e.g. We write to advise you.) Instructions (e.g. You go left, turn rightà ¢Ã¢â€š ¬Ã‚ ¦.) Stories (e.g. In act one, Hamlet meets the ghost of his father.), which Huddleston calls the historic present. In expressions of understanding such as hear, see, gather (e.g. I hear youre getting married.) Finally, the simple present can be used in newspaper headlines (e.g. RUSSIANS RAISE OBJECTIONS) Since there are so many instances of when to use the present simple, is there any way to summarize all of these? I concur with Lewis explanation that the present simple: 1-Expresses an event as a total single point in time. 2-Expresses an event as a matter of fact. 3-Expresses an event as immediate rather than remote. The present progressive tense Both the simple and progressive forms usually tell us that an action takes place. But the progressive forms also tell us that an activity is or was, or will be, etc. in progress, or thought of as being in progress. In other words, the present progressive tells us that the speaker sees an action as taking place over a period of time as opposed to a point in time. In addition researchers would add that the speaker sees the period as limited (Lewis 1986; Leech, 1975; Huddleston, 1984; Quirke, 1985). The present progressive tense is formed with the present of be (am/is/are) (which adds aspect and voice), said by Quirke to be the finite verb, plus the ing form (the non-finite form) (Quirke 1985, p. 120). There are no complications with the additional ing form; however the spelling of the ing has some irregularities and needs to be taught to students e.g. write, writing; run, running; begin, beginning; lie, lying). (Alexander 1988; Huddleston 1984; Quirke 1985). Question formation takes place by switching the place of the auxiliary be and the subject. Negation is achieved by inserting not between the subject and the auxiliary or by contracting nt with the auxiliary verb forms (with the exception of the first person singular form am) (Quirke, 1985). In the classroom, the classical reason given for why we use the present progressive is that it shows an uncompleted action in progress at the time of speaking. To emphasise this, we often use adverbials like now, at the moment, just, etc. For example, Hes not home at the moment, hes working. (Quirke 1985). The present progressive can also be used to describe actions which have not been happening for long, or are thought of as being temporary situations, and which are going on around now, e.g. Abdullah is living with his aunt until he can find a place of his own.. A further use of the present progressive is to refer to activities and events planned for the future. We generally use adverbials in such sentences unless the meaning is clear from context, e.g. Were spending next Thursday in Abu Dhabi. (Azar 1989; Huddleston 1984; Quirke 1985). The present progressive can also be used to talk about developing and changing situations, e.g. That child is getting bigger all the time. (Swan 1980). Sometimes the present progressive can be used to talk about feelings, such as I am feeling fine. or My back is hurting me.. The present progressive is used to show repeated actions along with adverbs such as always, constantly, continually, forever, perpetually, and repeatedly, such as He is always helping people.. In this sense it conveys not temporariness, but continuousness. (Leech 1975; Huddleston 1984). The present progressive also is used to show repeated actions that are happening around now, e.g. He is studying a lot of English these days. Why is he going to the library? (Swan 1980). Dynamic versus Stative Verbs in the present simple and the progressive tenses Dynamic/progressive verbs refer to verbs which show actions which are deliberate or voluntary, e.g. Im building a house., or changing situations, e.g. Hes becoming fat.. Dynamic verbs can be used in both the progressive as well as the simple forms e.g. I eat at 5:00 (everyday). as opposed to Im eating now.. Stative verbs (also known as non-progressive verbs) are verbs which indicate a state, condition or experience. Specifically, stative verbs fall into categories such as feelings (like, love), thinking/believing (think, know, realize), wants and preferences (need, want), perception and the senses (smell, see), and being, seeming, having, and owning (seem, look, appear). Stative verbs are generally not used in the progressive forms (Quirke 1985). However some stative verbs can be used in both the present simple and the progressive tenses, which results in a different meaning in each form, e.g. Im thinking of a solution. as opposed to I think he is the best man for the job. or These flowers smell good. as opposed to Latifa is smelling the flowers in the garden.) (Alexander 1988; Azar 1989; Azar 1986; Quirke 1985). The present simple versus the present progressive Swan makes note of a number of areas where students might confuse the present simple with the present continuous. A. We use the simple present to talk about things that are true for the present period of time, or, as was noted above, to say this is how things stand at the present moment for the foreseeable future. However, if the event is temporary and is taking place right now, we use the present progressive. Afrah studies at the Higher Colleges. Afrah is studying her English lesson. B. We use the present progressive to talk about habitual actions if these are happening around the moment of speaking. Fayrouz and Fatima are preparing for the Eid holidays. However, if the habitual action is not closely connected to the moment of speaking, we generally use the present simple. I go to Saudi Arabia once every three years. C. Verbs that refer to physical feelings can sometimes be used in either the simple present or the present progressive. I feel great! or Im feeling great! My head hurts. or My head is hurting. (Swan 1980). PART TWO A grammatical description of the Arabic present simple and the present progressive In this part of the paper, I would like to give readers a very brief background of the Arabic verb system in regard to the simple present and the present progressive. The Arabic verb system is very complicated. However, this does not mean that a teacher has to master the Arabic language before s/he is able to pinpoint errors that may be a result of the interference of Arabic in English. One can study the Arabic language with the goal of simply understanding the structure, rather than with the goal of speaking and writing in the language. Let us first look at the present simple, then the present progressive, and finally the verb to be since all of these grammatical items are specifically relevant to the particular problem at hand. A.The Present Simple In Arabic, the formation of the present simple is radically different from English, since Arabic uses a root system made up of the three most important consonants (though two or four consonant roots do sometimes occur). In Arabic the three basic consonants (the root) stay the same but it is by changes in the vowels, the suffixes and the prefixes that tense and number are indicated. It is vastly more complicated than the way some English verbs change tense by changing vowels, e.g. give, gave. For example, the sentence, he learns could be represented phonetically by ya-droo-soo. The d-r-s is the root, ya is the part that indicates this is a third person singular masculine verb (though this is not the pronoun). The pattern of the vowels and consonants (ya + c1 + c2+ oo + c3 + oo), lets the speaker know that this is the present tense. In contrast, the past could be represented by a different pattern; hence, he learned, dar-ah-sah has the pattern (c1 + ai or ah + c2 + ai or ah + c3 + ah) (and this is just one pattern out of ten!) From a sentence point of view the verb in Arabic is not necessarily treated as the nucleus of a sentence and, in the case of the copula verb BE, can be omitted entirely (as we shall see below). The verb can also be placed at the beginning of the sentence. Like its English counterpart, the present simple tense in Arabic expresses a habitual action. There are other functions, but they are not relevant to this discussion. B.The Present Progressive In general, the present simple form is also used in Arabic to express the idea of a continuous action occurring in the present. Hence, the English sentence He is working now. in Arabic becomes He works now. (represented phonetically by huwwah yaamaloo al eyn.) What is he doing? in Arabic becomes What does he do? (represented phonetically by mehzah yafaaloo al eyn?) Hence, in almost all cases, the present simple form is used to show the idea of continuous action in the present. However, there is a single verb form in Arabic called the ism-ul-fail which is the exact parallel to the idea of continuous action. However, the difference in Arabic is that the ism-ul-fail is used very sparingly compared to English and then only for some very specific verbs of movement, or verbs that indicate changing from one state to another (going up, going in, going down, walking to a place, leaving a place, etc.). Since the ism-ul-fail is radically different in form from the English progressive it is doubtful that any interference in form occurs. C.A Few Points About The Verb BE as a Copula Although BE as a copula is not the focus of this paper, it does deserve mention here for two specific reasons. The first point is that BE in Arabic, when it is the copula in the present tense, is unwritten and unspoken (although this is not true of the copula in the past tense or the future where it is written and spoken). (Kharma, 1989, p. 89). For example, the literal translation of the sentence Ahmed is a student. is Ahmed student.. So it is conceivable that students might leave BE out as a copula OR as the helping verb in the present progressive because it does not exist in the present tense in Arabic (although there are other additional reasons why students might forget to add it to the present progressive as we shall see). The second point is that BE is used so often in English, in so many different kinds of structures, and that it is so irregular, that it might simply add to the confusion of students (Kharma 1989, p. 161). Students who keep on being corrected for leaving out the verb to be when it is necessary, may for example, hypercorrect themselves and start to write it everywhere. Again, we shall explore this issue further below. PART THREE A look at some common written errors made by Arabic speaking students when using the English present simple and present progressive Finding the exact causes of any error can be a difficult and meticulous task. This is partly because there may be multiple reasons as to why students make one particular error and these causes may also overlap at any given time. In addition, it is extremely problematic, even for a native speaker of both Arabic and English, (which I am) to know exactly what is going on linguistically in the mind of a student when s/he makes such an error. However, having said that, even with these obstacles, we can at least make some good hypotheses and lists of possibilities as to why these errors occur with our own students. As a result, we will be able to generate classroom strategies and methods in order to correct and remedy these sorts of mistakes. The following categories of errors are the most common that I have found in students written work with regards to the simple present versus the present progressive. I will look at each category in turn, and offer an analysis of the sources for these types of error. Category One Fatima studies now. Ahmed does his homework now. In these sentences, the intention of the Arabic speaking writer seems to be to convey the meaning of what in English would be a present continuous action, expressed by the present continuous tense. This is clear by the use of the adverb now or in the case of other examples not shown here, from other adverbs or the context of the sentence. In examples one and two, the Arabic speaker seems to be transferring the rules of his native language into English. The Arabic speaker usually uses only the present simple to express events that would be expressed in English by both the present simple and the present continuous. Category Two Mariam cant talk, she eating now. This kind of mistake is a bit more problematic in terms of analysis. It could be that the Arabic speaker, feeling that the full meaning of the action is expressed in the verb with the ing, has decided that the am/are/is forms are redundant and unnecessary. It could also be the case that this mistake is a direct transfer of a particular grammatical form in Arabic. In certain cases Arabic speakers do express the present continuous with a verb and prefix change (called ism-ul-fail), but without the corresponding be form. For example, the literal translation of the sentence Ahmed is running. is Ahmed running. . Category Three Are you knowing the way to Dubai? I am wanting to see my family. In this case, the student has learned the present progressive form, but is over generalizing it to all verbs (or perhaps does not remember or has not been taught the rules for exceptions such as the above). These types of errors could very well be intralingual. This over generalization could also be found in sentences that have the function of explaining, demonstrating teaching or narrating such as: Next I am pouring the oil into the cooking pan. Ali is passing the ball to the goalkeeper. Category Four I am live in Abu Dhabi. We are study English. This category is probably the most difficult to analyze. This is because it is unclear whether the Arabic speaker is making the mistake of adding the additional am/is/are form while trying to use the present tense, or making the mistake of forgetting to use the present participle while trying to use the present progressive tense. That is, did the speaker intend to say I live in Abu Dhabi. and use the extra am form by mistake, or did s/he intend to say I am living in Abu Dhabi. and forget the correct present participle form? Of course, there are other possibilities but these seem like the two most likely. We must obviously look at the context of the paragraph to see if we can get the gist of what the speaker meant. The following is a more detailed analysis of these two possibilities from the standpoint of the students reasoning. 1. If we believe from the context that the student was trying to use the present simple and added the additional am in error, then the following analyses apply: A. The student may be confused by the lack of inflectional endings in English, since Arabic is a highly inflected language, and every personal pronoun has a distinct corresponding inflected verb form. The similarity of the verb forms in I live, you live, etc. may seem very awkward to the Arabic speaker. Hence, they may want to remedy the situation by distinguishing the verb forms in some way by, for example, adding an exceedingly familiar and overused verb form like am, are, or is. B. The student may be over generalising based on what they have learned about the present continuous. That is, they may have learned how to form the present continuous quite easily since there is no mother tongue interference from Arabic, (although they may not have mastered its use). They then may go on to conclude that every verb in the present simple or present continuous in English needs to be preceded by am/is/are. C. Similarly, the student may be hypercorrecting. They may have been corrected so many times for forgetting to use the verb BE in their sentences e.g. Ahmed happy, that they may start to feel that every sentence needs the verb BE. 2. However, if we believe that the student was trying to use the present continuous tense and used the present simple live (instead of the present participle living), then the following analyses apply: A. The student may not have correctly understood how to form the present participle by adding ing to the end of the verb. B. Perhaps students have simply forgotten to add the ing prefix because the structure is so different in their language. This is by no means an exhaustive analysis. However, these are, from my experience and collaboration with other colleagues, both native and non-native speakers, some of the major possibilities. PART FOUR Pedogogical implications of the above research for teaching the present simple and the present progressive to Arabic speaking students From the evidence I have presented here, I believe it is clear that many of the mistakes in using the present simple and the present progressive in form (such as omission of the verb to be in the simple present for Arabic speakers, e.g. I studying), as well as other mistakes in usage (e.g. using the simple present when the present progressive is required) seem to be traceable directly to Arabic mother tongue interference. Based on my analyses, reading and discussion with colleagues, I do feel that in this particular area, teachers of EFL to Arabic speakers must consider mother tongue interference as a major impediment to learning the present tense versus the present progressive. If we know that mother tongue interference is the cause of many errors, what should this imply for our teaching? One thing which I think it does not imply is that we teach English from the point of view of the mother tongue. For example, trying to get students to understand English grammar through word for word translations or using the grammatical structure of Arabic to help students to understand the grammatical structure of English are only useful in certain cases, and then only by someone who is a master of both languages. My experience in reading the research, being bilingual and talking to Arabic speaking students who are at the final stages of their English studies leads me to believe that, at least in the case of Arabic and English, that the two languages are sufficiently different that they are both best looked at in their own respective grammars. Students must be made, not only to think in English, but to understand English grammar in terms of English grammar without constantly switching back and forth to compare it with Arabic. Such practices are ineffective and will cause confusion among students. As Lewis says students should never expect the foreign language to be like their ownà ¢Ã¢â€š ¬Ã‚ ¦..the fact that English has verb forms that contain [be] as an auxiliary does not suggest that other languages ought to have a corresponding formà ¢Ã¢â€š ¬Ã‚ ¦.students should be positively encouraged to explore the foreign language within itself rather than through the expectations they bring from their own. (Lewis, 1986, pp. 164-165). In addition, I should add that intralingual factors can also be at work when students make such errors (in addition to context specific factors like student motivation, teaching style and competence, etc.). For example, on the intralingual side, we know that students of ESL from many different language groups and even children make common mistakes with the verb to be. Therefore, many such mistakes might be intralingual. (Mattar 1989). Hence, when we try to analyse our students errors we should not be prejudiced to any one theory and we should try to be open to looking at all possible sources of errors. What we as teachers should be doing in the classroom is continually collecting research on student errors and student learning styles in order to form hypotheses about why such errors occur and why such one approach worked and another didnt. We should then be trying to test these hypotheses to see if they are true or not, and afterwards share this information w ith other teachers in similar situations. Only then will we be able to understand why students make errors and what is the most effective way to correct them. Cell Membrane: Structure And Function Cell Membrane: Structure And Function A cell is a dynamic and a complex structure surrounded by a membrane known as the plasma membrane. This acts like a barrier between the inside of the cell and the outside resulting in different chemical environments on the two sides. The cell membrane is not restricted to the outer surface but is also present inside surrounding the organelles. These biological membranes have played a crucial role in the evolution from prokaryotes to multicellular eukaryotes. In prokaryotes, there is only one type of membrane present i.e. the plasma membrane but the unicellular eukaryotes have intracellular membranes compartmentalizing its contents into different functional chambers known as organelles. Each organelle though performs its own specific function, they cross-talk with each other via these membranes in order to work as a unit. Further, different cells in multicellular eukaryotes communicate with each other through these membranes. The membrane, therefore serves a dual purpose of both protecting the interior of the cell from its external environment and also provides a communication interface between the cell and its surroundings or other cells. The diverse functions performed by biological membranes can be attributed to the molecular composition and structure of these membranes. Models for Cell Membrane Structure It took almost a century to develop the present accepted model of a cell membrane based on various physiological and biophysical studies. Physiological experiments involving the transport of molecules and ions across the membrane by Overton in 1899 suggested that the membrane is composed of lipid molecules. Later, Langmuir (1917) showed that lipids when spread on water using Langmuir trough form a monomolecular layer on the surface of the water by calculating the area per lipid molecule. The hydrophobic tails of these lipids were bent and protruding out from the surface of the water. When this method for measuring the area per lipid molecule was applied to the lipids extracted from the known amount of erythrocyte membranes, Gorter and Grendel (1925) concluded that the lipids exist as a bilayer and not a monolayer in a membrane giving birth to the lipid- bilayer membrane model. In 1935, Danielli and Davson elaborated on the model based on the studies measuring the surface tension that membranes are made up of phospholipid bilayer sandwiched between two protein layers. Based on optical imaging of membrane morphology using electron microscopy, Robertson argued that the basic structure of all the membranes is same and proposed the Unit Membrane Model in 1959 []. Several other studies [review or book] suggested that the lipid bilayer has fluid-like properties with lipids and proteins floating in it. Studies of proteins present in erythrocytes membrane and that extracted from other membranes led Singer and Nicolson to classify membrane proteins as peripheral and integral proteins; and finally proposing the Fluid Mosaic Model in 1972 []. This is the most accepted model describing the structure of a cell membrane. According to this model, mosaic of protein molecules is embedded within the fluid of lipid bilayer which is supported by the freeze-fracture studies of the plasma membrane (Figure). Composition of Membranes Membrane Lipids The lipid bilayer is only 5 to 10nm thick organized in distinct regions primarily attributed to the hydrophobic effect caused due to the amphipathic nature of these molecules with both polar and the non-polar regions (Figure). The interactions of these regions with the aqueous environment have been studied with various techniques like x-ray reflectometry,[1] neutron scattering[2HYPERLINK http://en.wikipedia.org/wiki/Lipid_bilayer#cite_note-Zaccai1975-1] and nuclear magnetic resonance. In order to exclude the non-polar regions from the aqueous environment, lipid molecules arrange in such a manner so that the hydrophobic tails point inwardly towards each other and the polar head groups are exposed on the outside facing the water. The outermost region on either side of the bilayer is completely hydrated and is typically around 8-9Ã… thick. The hydrophobic core of the bilayer is typically 3-4  nm thick. The intermediate region is partially hydrated and is approximately 3 Ã… thick. These lipid molecules arrange spontaneously naturally or artificially in solution to form structures like micelles and liposomes (Figure). Micelles are monolayer spherical structures formed by lipid molecules in aqueous environment. On the other hand, liposomes are concentric bilayer of fluid-filled vesicles surrounding the water compartment on both the surfaces. The membrane of the animal cells is composed primarily of three major types of lipids: phospholipids, glycolipids and cholesterol with phospholipids being the most abundant (Figure). The polar head groups of these phospholipids contain a phosphate group and either a glycerol (known as phosphoglycerides) or sphingosine. There are four major phospholipids present in the animal cells, three are phosphoglycerides namely phosphatidylcholine, phosphatidylethanolamine and phosphatidylserine; and the fourth sphingomyelin is the only sphingolipid. The heads of glycolipids contain a sphingosine with one (known as cerebroside) or more sugars (known as ganglioside) attached to it. Cholesterol is a sterol molecule with a small hydrophilic hydroxyl group and a rigid ring structure that stabilizes the bilayer. Membrane Proteins The membrane consists of different types of proteins accounting for 25-75% of the mass of the membrane and are categorized based on their interactions with the lipid bilayer (Figure). Moreover, the manner in which a protein is associated with the membrane is indicative of its function. Integral or intrinsic proteins are embedded with in the lipid bilayer. These could be transmembrane proteins spanning the entire length of the bilayer and possess hydrophobic domains which are anchored to hydrophobic lipids and hydrophilic domain interacting with external molecules. They could have only one membrane-spanning (single pass transmembrane proteins, e.g. glycophorin) or multispanning (multi-pass transmembrane proteins, e.g. band3 protein of erythrocyte) segments. The transmembrane segments have helical e.g. bacteriorhodopsin or ÃŽÂ ²- barrel structures. These proteins can be extracted from the phospholipid bilayer only by disrupting the hydrophobic interactions by using detergents like S DS or Triton-X 100. Peripheral or the extrinsic proteins, on the other hand, are loosely bound to the hydrophilic lipid and protein groups on the surface of the membrane by weak ionic interactions. These can be easily removed with high salt or extreme pH without disrupting the phospholipid bilayer. Lipid-anchored proteins are covalently bound to lipid molecule which in turn anchors the protein in the cell membrane. The lipid can be phosphatidylinositol, a fatty acid or a prenyl group. Membrane Carbohydrates Carbohydrate moieties are present on the non-cytoplasmic surface of the membrane covalently attached to either protein or lipid molecules forming glycoproteins or glycolipids. These carbohydrates help in orientation of protein molecules on the cell surface and sorting in cellular compartments. The glycocalyx or the cell coat is the layer of carbohydrates on the cell surface that protects it and participates in the cell-cell interaction. The carbohydrates of the glycolipids of the erythrocytes membrane determine the ABO blood groups in human. Fluidity of Membranes Under physiological conditions, phospholipid molecules in the membrane are in the liquid crystalline state and the molecules are not physically attached to each other so, they can move within the bilayer. These movements could be within a monolayer i.e. rotational and lateral or between two layers i.e. flip-flop. Flip-flop movements are rare and slower compared to the other two as it requires energy for a lipid molecule to traverse from one layer to the other. Besides, some proteins also move in the membrane as concluded from studies based on human-mouse cell hybrids produced by fusion of human and mouse cells [Frye and Michael Edidin in 1970] and FRAP (fluorescence recovery after photobleaching) experiments (Figure). Fluidity in the cell membrane is attributed to its lipid composition. The cis-unsaturated fatty acids with kinks in their hydrocarbon tails and shorter lengths of the tails increase the fluidity by preventing the ordered packing of phospholipids in the bilayer. Cholesterol molecules present in the bilayer affects its fluidity differently at different temperatures because of its rigid ring structure. It reduces the fluidity by decreasing the movement of adjacent phospholipids but at low temperatures, it increases the fluidity by preventing solidification [Alberts]. Fluidity of the membrane allows different molecules like proteins to interact with each other to perform various processes like transport of molecules and cell signalling. Moreover, membrane fluidity is required for various cellular processes like cell movement and cell division. Asymmetry of Membranes The two leaflets, that is, the inner and the outer monolayer portions of the lipid bilayer differ in their physical and chemical properties. This is due to the asymmetric organization of the various components of the membrane. For example, glycolipids and glycoproteins are always present on the non-cytoplasmic surface of the plasma membrane. Membrane regions differ in their lipid composition. The outer leaflet contains predominantly phosphatidylcholine and sphingomyelin whereas, the inner leaflet contains phosphatidylethanolamine and phosphatidylserine. The inner leaflet also consists of phosphatidylinositol which play a key role in the transfer of stimuli from the plasma membrane to the cytoplasm [Cooper]. The membrane proteins also differ in their distribution in the two leaflets. For example, spectrin and ankyrin are present on the inner surface of the erythrocytes membrane forming a fibrillar membrane skeleton. GPI-anchored proteins ar present on the external surface of the membr ane. The asymmetry of the membrane suggested different roles played by the components of the membrane present on the two surfaces (Figure eg intestinal epithelial cell membrane:Tight junction , lateral movements). Lipid Rafts The plasma membrane of eukaryotic cells have specialized regions known as lipid rafts which differ in their composition from the rest of the membrane. These detergent-resistant and heterogeneous microdomains are rich in cholesterol, sphingolipids and certain proteins. Lipids in these rafts are more highly ordered and tightly packed as compared to the rest of the lipid bilayer. Various studies have attributed diverse roles like in transport of cholesterol, endocytosis, signal transduction, intracellular trafficking and neural development and function to these lipid rafts. Caveolae is an example of lipid rafts which are the invaginated domains in the plasma membrane. In caveolae, a protein caveolin is associated with the cholesterol in the lipid raft. It plays roles in membrane internalization and cell signaling. [Pike et al, 2002; Wary et al, 1998; Huang et al, 1999; Rothberg et al, 1992] (Review: Razani Lisanti, 2001. Exp. Cell Research 271: 36-44). Might not in endocytosis [Thompsen et al, 2002] see lipid rafts 4 references Functions of membranes: Membranes act as boundaries between the cell and its environment and are essential for maintaining the integrity of the cell and the various membrane-bound organelles within the cell, regulating the transport of materials into and out of the cell, responding to external and internal stimuli, and cell-to-cell recognition. The proteins present on the inner surface of the plasma membrane provides shape and maintains the integrity of the cell by anchoring the cytoskeleton found underlying the cell membrane in the cytoplasm. The major component of the cytoskeleton of the most well studied erythrocyte membrane is the fibrous protein spectrin. This protein interacts with other peripheral proteins like ankyrin, actin and tropomyosin. Dystophin, a member of the spectrin family is found in the membrane skeleton of muscle cells. The importance of these proteins is suggested by the fact that mutations in dystrophin leads to muscular dystrophy. Regulated transport of materials across the membrane is due to the amphipathic nature of the lipid bilayer. Therefore, the membranes are selectively permeable and the ability of a molecule or ion to traverse the bilayer depends majorly on its polarity and also on the size. Non-polar molecules like O2, N2 and benzene and small polar molecules like H2O, glycerol, urea and CO2 can pass the membrane but large uncharged (e.g. glucose), polar molecules (e.g. sucrose) and ions (e.g. H+, Na+, HCO3, Clà ¢Ã¢â€š ¬Ã¢â‚¬Ëœ) are not able to diffuse easily across membranes. Hence, various mechanisms are required for transport of materials across the membrane, including simple diffusion, facilitated diffusion and active transport for micromolecules and exocytosis and endocytosis for macromolecules. In simple diffusion, substances diffuse down their concentration gradient. In facilitated diffusion, movement of molecules down the concentration gradient is facilitated by channel and carrier proteins (e.g. glucose transporter). On the other hand, active transport requires energy to move solutes against their gradients and can be classified into primary or secondary active transport depending on the source of energy. The primary active transport depends on the hydrolysis of ATP and is of different types: P (e.g. Na+ K+ ATPase, Figure), F and V types and the ATP-binding cassette or ABC transporters. In secondary active transport, specific solute indirectly drives the active transport of another solute and does not involve the hydrolysis of ATP. Secondary active transport may include either symport (e.g. Na+/Glucose transporter) or antiport (Cl ­-/HCO3 exchanger). The macromolecules such as proteins and polysaccharides are transported by endocytosis (from inside the cell to th e outside) and exocytosis (from outside into the cell) (Figure). Cell membrane is also involved in cell-cell communication. Specialized membrane structures like gap junctions in animals and plasmodesmata in plants provide the cytoplasmic continuity between cells. Tight junctions and desmosomes help in attachment of a cell to other cells or the extracellular matrix forming tissues. Membrane also maintains cell potential by creating chemical and electrical gradient. Cell signaling: Signals through chemical messengers (chemical or electrical stimuli) acting on the membrane receptors most of them being proteins. These signals are then transduced in the cell leading to a cascade of events in the cell. Specific for different cells like Gprotein, Tyrosine-kinase receptors Peripheral proteins act as enzymes e.g. and receptors In summary, biological membranes are the complex and dynamic structures composed of variety of proteins embedded in the fluid of the lipid bilayer. The amphipathic nature of the lipid bilayer and the diversity of membrane proteins are responsible for the involvement of biological membranes in large number of cellular processes.

Importance of Having an Inter Professional Team

Importance of Having an Inter Professional Team This essay is meant to throw light on the importance of having an inter professional team that would make the service delivery to patients easier. In this essay I will discuss the roles played by nurses and other professionals in the team. The essay will reflect the efficiency of such a team and their work distribution and involvement. I will highlight the ways in which a team of professionals will work together to take proper decisions during emergency situations and tackle them effectively. The essay will also critically evaluate the various concepts of inter professional team work. An interprofessional team is a group of people who have a certain common goals or objectives which drives them to work together by setting aside individual goals. Inter professional team can be defined as a dynamic process involving two or more health care professionals with complementary backgrounds and skills, sharing common health goals and exercising concerted physical and mental effort in assessing, planning, or evaluating patient care, accomplished through interdependent collaboration, open communication and shared decision-making, and generates value-added patient, organizational and staff outcomes (Xyrichis and Ream 2007). Freeth et al (2005) defined inter professional team work as when two or more professional learn with, from and about each other to improve collaboration and the quality of care. The healthcare sector started showing interest in the interprofessional working during the early 1990. (Institute of Medicine, 1998;ONeil and Pew Health Professions Commission 1998;ÂÂ  Pew Health Professions Commission 1995a,ÂÂ  1995b,ÂÂ  1998). The Association of American Medical Colleges, the Accreditation Council for Graduate Medical Education, the American Association of Colleges of Nursing suggested that the graduates must have enough knowledge in interprofessional collaboration (Varkey, Reller, Smith, Ponet, OsbornÂÂ  , 2006). Varkey et.al (2006) also pointed out that there should be enough cooperation between the various professionals in healthcare field for the success of this profession. But unfortunately this fact is not included in the curriculum of the different medical schools in USA. Inter professional teams are more effective in rehabilitating the patients than individual health care professionals. The number of patients having positive impact by the inter professional service is larger than those by individual service providers. A very strategic role played by nurses is highlighted now. The nursing tutors face the dual challenge of preparing their students enter into nursing profession as well as equip them to cooperate effectively with other health practitioners (Lattuca, 200l;ÂÂ  Newell, 1998). An interprofessional team is working to provide service in a properly planned and systematic manner. In the health care sector inter professional teams are meant to develop groups that works towards efficiently rendering care to the patients. These teams include nurses, doctors, and other health care professionals. For a team to be efficient role clarity to inevitable and this will help them define their own duties and responsibilities avoiding conflicts (West and Markiowicz, 2004). A team essentially will have a team leader who will lead the team and motivate them to render good service working together (Martin and Rogers 2004). A health care team will work effectively if there is stability in the team, this will make the team member in the group work with shared trust and understanding (West and Slater (1996); Gair and Hartery, (2001)). Interprofessional teams are of various types, they include multidisciplinary, interdisciplinary etc. In case of multidisciplinary teams the members are from various teams. These members set their own discipline specific goals and work towards achieving it. But ultimately the result is calculated as the total of all the disciplines (Dean and Geiringer 1990). The position of team members in the team hierarchy will affect the way in which the team functions and how it will render the service (Cotts, 1998). In case of a multidisciplinary team there exist subgroups of doctors, social workers, therapists and also subgroups which had nurses and other junior staff. Her study also unveiled the idea that the different subgroups had different perceptions about the inter professional teams. Inter professional team work is highly essential in operation theatres and intensive and trauma care units. Since these are the emergency units of a hospital the situation of such units cannot be predicted and thus highly challenging. The interprofessional team may have to work highly efficiently and together. There exists a high rate of tension and stress in the team members in such emergency situations. According to McWilliam et al (2003), interprofessional working is a very difficult task for health care professionals. The patients didnt get the full benefit of interprofessional working due to the misunderstanding between the health care professionals regarding the policies and procedures in it. Mistreatment of elders is a serious issue and its growing day by day. It is the responsibility of nurses to identify and prevent such occurrences (Baker Heitkemper, 2005). The nurses have a variety of roles to play in an Inter-professional elder mistreatment team. At present the roles involve screening and assessment, mandatory reporting, direct care, and complaint investigation. Elder mistreatment (EM) is a very complicated issue and can be effectively solved through inter-professional association. Critics like Bion (1961) say that the interprofessional teams fail to focus on the real task they should be doing. The primary tasks for which they have come together is forgotten most of the by the interprofessional teams. Whenever there is an issue the teams to fail to reach at a consensus and they do not take proper decisions on the issue (Strokes 1994). The meetings conducted in order to take decision on the matter are just a waste of time. These assumptions are based on the work group mentality theory. Critics of interprofessional team have questioned the values of the team. It is said that the teams are not well managed and they do not work properly and responsibily. Negotiation theory puts forward the perspective of negotiating the personal and professional goals. (Strauss, 1978) The negotiations by professionals in the health care field have played a critical role in molding the characteristics of an interprofessional team. Loss and change theory reiterates that the health care professionals like doctors and nurses lose their professional identity as they are working in a team, this will lead to developing an improper relationship and improper behavior in the team (Atkins, 1998). Thus it critically points to the inter professional teams in that it wouldnt serve the purpose of forming a team the unhappiness of the team members can lead to inefficient functioning. The increase of cost in hospitals will also result if there is lack of proper communication between the professionals like doctors, nurses and staff and also if they are not coordinated well (Gavett, Drucker, McCrum and Dickinson, 1985). The roles played by nurses in the interprofessional teams are fast evolving. The importance of specialist skills for nurses is now recognized and new role have come up. The Macmillan nurse is an example of such new roles and they possess skills in palliative care and are expected to look after patients with terminal illness. Another group called night practitioners literally run the hospitals at night. They are skilled to assist any department and are sometimes considered better than junior doctors too (Martin Rogers, 2004) While working in an interprofessional team, there is an increased chance of conflict between the team members regarding the superiority in the team. The truth is everyone is equal while working in a team and nobody should themselves subordinate to anyone. But sometimes the nurses and their opinions are ignored in an interprofessional team. Such events makes them reluctant to be a part of such teams (Martin Rogers, 2004). Task shifting is a common practice among the professionals now days (Reeves et.al, 2010). This would help the traditional professionals to relieve of their heavy workload. The nursing practitioners and physician assistants are such roles (Hooker McCaig, 2001). The multiplicative effects model of interprofessional working views it more than the sum of its parts. Here the synergy obtained from such work is described (Leathard, 1994). According to this model, interprofessional working improves the contributions of individual team members and thus will help in the overall development of team. Decision making is an essential in ingradient of all teams; it measures the efficiency of the group. Decision making in case of an interprofessional team also play key role deciding its service delivery process. The usual situation that happens in such teams is the unavailability of proper team leader and also reaching at a common consensus. The decision taken in team has the idea input all the members that needs to driven well in one direction for increasing effectiveness of the work the team does. Most of the important decisions concerning the activities of the team are taken mostly by the Doctors, or the medical staff in an inter professional team in hospitals. Solving important problems and resolving conflicts are the aims of masking decisions (Neil, 1978). There are a few hindrances for nurses to be part of interprofessional teams. The health care sector has shortages or less number of nurses, and those nurses who are available have increased amount of work. As a result of which there is a limitation in case of inter professional support and collaboration (Mckay Crippen, 2008). Another barrier that can be highlighted is the disinterest on the part of other departments to participate and actively involve in the team and work together. The culture and hierarchy of the organization also plays a role in the formation of teams in the organization. According to Henneman.et.al (1995) Collaboration involves a partnership characterized by mutual goals and commitments in which participants willingly become involved in planning and decision making. Henneman.et.al (1995) also proposed that collaboration is a process by which members of various disciplines (or agencies) share their expertise. Accomplishing this requires these individuals understand and appreciate what it is that they contribute to the whole. Many authors have suggested ways to make the intercollaboration more effective. According to Fullan (1993), effective collaborations operate in the world of ideas, examining existing practices critically, seeking better alternatives and working hard together at bringing about improvements and assessing their worth.ÂÂ   The National Network for Collaboration (NNC) put forward a frame work for effective collaboration and advocated that it should possess a common vision, problem, a desired outcome etc. NNC also pointed out that the members of the collaboration must share this vision and contribute equally. The NNC sees collaboration as an inclusionary process which should be constantly engaged and must strengthen the commitment and must identify that relationship building and maintaining is the key factor for the success of collaborations and they must try to sustain a win-win relationship. According to Garner (1995) and Hoeman (1996), it should be by means of collaborative communi cation rather than shared communication that the interprofessional team approach evolves. Efforts were made from the part of many authors for increasing the literature on interprofessional education for health professional students. But Cooper, Carlisle, Gibbs, and Watkins (2001) pointed out this literature to be diverse including a relatively small amount of research data and much larger amounts of evaluation literature. There were almost thirty works done on interprofessional education and all of them aimed to increase the level of co-operation and understanding between the members in interprofessional teams as well as to encourage a high quality care for the patients. There are a number of social science theories that explain the concept of interprofessional team work. Merton (1968) put forward theory in three modules. They are the micro, mid range and macro theories. The social sciences approaches that come under these three groups include: Micro: psychodynamic perspective by Bion, Menzies, Marris, social psychological perspective by Tejfel and Turner, Brown Interactionism by Goffman and strauss All the above approaches that come under the micro group are of the rational type that consolidates the team functions, identities and interactions. Midrange : Activity theory by Engestrom Institutional influence by DiMaggio and Powell Professionalization by Freidson These three approaches or theories are processual, organizational and contextual. Their task is to understand team activities, relation and performance, the relations between professions respectively. Macro: Discourse theory and surveillance theory by Foucault They are of the contextual type that deals with the impact of society and social interaction of with respect to the interprofessional team work. There are a set of models supporter by theories that help provide the inter professional education well in the health care sector that enables the health care professionals perform well and deliver quality service. These models are whilst behaviorism, cognitivism and constructivism (Schunk D 2003). I will working for the betterment of the service provided to a patient using the things I learned. Working in an interprofessional team is has made me get involved with the Doctors and other professional in the field and has helped to build a strategy that elevates the level of service rendering process. As a nurse am able to act in the right way a right direction in case of any emergency and otherwise. From now I will be able to put into practise the concept I learned. The model that I would use is the Kolbs model of reflection. It is a process whereby, individuals, teams and organizations attend to and understanding their experiences and consequently modify their behaviour. The model mainly has 4 important aspects: Experiencing means really doing the task and experiencing the whole process. Reflecting- in this step the work is reviewed in terms of experience and the real process. Conceptualisation- here the various important occurrences and tasks are analysed and their connections among the events are noted. Planning- the events that have been understood will be analysed well in order to envisage the occurrences in future. This will help to prevent any improper events happening and build a proper strategy to do the next task. The Kolbs reflection model if one of the best models for teams. In case of a team there are aspects like: Doing- same as experience, where the team does the task or the action. Reflection- after the action, the team members openly discuss the whole process and share their views and experience. Interpretation- the members of the team now work with common identity and culture and as a team by leaning behind individual interests. Planning- in the final step team works according to the joint decisions and plan out ways to committing the action. Finally I would say that in any sector especially the health care there is an elementary requirement of having an inter professional team. The team in all ways will help in providing superior service since the decisions are taken as a team and under common grounds.

Americas Advantages in the Revolution Essay -- essays papers

America's Advantages in the Revolution In the second half of the eighteenth century, the British were faced with rebelling colonies. Finally realizing that they had to fight to keep their colonial possessions, the British sent troops to America. Once the battles began in America, the British were not impressed with the colonial military, but the weak militias soon proved to be effective. With foreign aid from France, American devotion, and the lack of British vigor, the Americans soon discovered the open doors of independence. In my opinion, the American advantages and the British disadvantages proved to be the downfall of the English in the American Revolution. Even though the British army was larger, the American army proved to have talented fighters. The Continental Army and the state militias were essentially the two military organizations of the Americans. Throughout the war, the Americans employed only 231,771 men, which meant that the American forces rarely numbered over 20,000. Compared to the British, the American army was small, but their military tactics and skills were excellent. From a distance of 200 yards, an American rifleman could easily kill a British soldier. Many men observed that the British plainly fired in the general direction of the Americans, while the Americans aimed for the heads of the British. Also, the Americans had many more competent and talented leaders. George Washington and Benedict Arnold were two of the most brilliant Ame...

the militia Essay -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Officially, a militia is part of the organized armed forces of a country that is called upon only in an emergency. There have been paramilitary groups with revolutionary ideas throughout America’s history, but today’s militia movement is a new more organized and violent presence (Meyers). Today the militia are unofficial citizens’ armies organized by private individuals, usually with antigovernment, far right agendas. They rationalize that the American people need armed force to help defend themselves against an increasingly oppressive government that is becoming part of a global conspiracy called the â€Å"New World Order† (Sonder, 2000). These armed groups call themselves militias; to both imply the image of the Minuteman of the Revolution and to try to claim legitimacy by asserting that these paramilitary groups were the â€Å"unorganized militia† of federal and state law. The causes for the militia movement are many, but mos t center around a fear of gun confiscation and the role such confiscation would play in their various one-world conspiracy theories. The major events, which helped to incite the movement, include the Ruby Ridge and Waco standoffs, the Brady Law and the Assault Weapons Manufacture Ban. The first groups began forming at the end of 1993; by mid-1994 (Sonder, 2000) there were a variety of such groups in many states across the country. While the media noted the emergence of this movement, little attention was paid to the phenomenon until late 1994, when civil rights organizations such as the Southern Poverty Law Center and the Anti-Defamation League released reports on the militia movement. According to the Southern Poverty Law Center most of these citizens’ armies have few members and are not involved in violent activities (Sonder, 2000). They are interested mostly in the purchase and use of firearms, in discussions of patriotism, and in playing weekend war games. However, there are more than a hundred of these groups, which probably have ties to violent right wing and racist organizations. The militia exploded into prominence, however, in April 1995 when early reports indicated that Timothy McVeigh and Terry Nichols, the Oklahoma City bombing suspects, had belonged to a Michigan militia, or that militia groups were in some way directly connected to the bombing.

Decision Making Across the Organization

The Martinez Company has decided to introduce a new product and would like to evaluate the costs of manufacturing through capital intensive and labor intensive manufacturing methods to determine which of the two methods to employ. The values to be used in the evaluation for capital intensive manufacturing are direct materials at $5 per unit, direct labor at $6 per unit, a variable overhead of $3 per unit, and fixed manufacturing costs of $2,508,000. The values for material, labor, and overhead are summed to find the total variable cost of $14.The labor intensive values are direct materials at $5.50 per unit, direct labor at $8 per unit, a variable overhead of $4. 50 per unit, and fixed manufacturing costs of $1,538,000. The research department of Martinez recommended an introductory price unit sales price of $30. Incremental selling expenses are estimated to be $502,000 annually plus $2 for each unit sold regardless of the method used to manufacture. Capital Intensive To calculate ca pital intensive estimated break-even point in annual unit sales of the new product the contribution margin per unit and contribution margin per ratio are necessary.The equation for contribution margin per unit is Selling Price + Variable Cost, or $30 + $14, for a contribution margin per unit price of $16. The equation for contribution margin ration is Contribution Margin per Unit / Selling Price, or $16/$30, for a contribution margin ratio of 53%. The break-even point in units is calculated by dividing the fixed costs by the contribution margin per unit value, $2,508,000 / $16 = 156750 units as the break-even point. The fixed costs divided by the contribution margin ratio, $2,508,000 / 53% = $4,702,500 break-even point in dollars. Labor IntensiveTo calculate capital intensive estimated break-even point in annual unit sales of the new product the contribution margin per unit and contribution margin per ratio are necessary. The equation for contribution margin per unit is Selling Pric e + Variable Cost, or $30 + $18, for a contribution margin per unit price of $12. The equation for contribution margin ratio is Contribution Margin per Unit / Selling Price, or $12/$30, for a contribution margin ratio of 40%. The break-even point in units is calculated by dividing the fixed costs by the contribution margin per unit value, $1,538,000 / $12 = 128,167 units as the break-even point.The fixed costs divided by the contribution margin ratio, $1,538,000 / 40% = $3,845,000 break-even point in dollars. Unit Sales Volume of Indifference The volume of unit sales at which the Martinez Company would be indifferent between the two manufacturing methods is calculated as Sales = Variable Costs + Fixed Costs + Net Income. The value for sales is equivalent to the sales price, $30, multiplied by the number of units sold. Variable costs of $14 for capital intensive and $18 for labor intensive are also multiplied by the number of units sold.Fixed costs were provided at $2,508,000 for cap ital intensive and $1,538,000 for labor intensive. Net income is assumed to be $0. The equation values for 180,000 units under capital intensive manufacturing and 240,000 under labor intensive manufacturing is the volume of units for each method to equal sales of $2,880,000, the point at which the annual unit sales volume would be indifferent. Conclusion Evaluating the costs of manufacturing help management to make crucial decisions about methods of manufacturing that will result in profit for the business.Evaluating the capital intensive manufacturing method versus the labor intensive method provides the values necessary to make business decisions. The circumstances in which the Martinez Company would employ a capital intensive manufacturing method for the new product, based on the numbers provided in the scenario, would be if the contribution margin and per unit cost were cheaper than the labor intensive values. In this scenario, the labor intensive values offer a smaller break-ev en point value for units and dollars than the capital intensive method of manufacturing.

Unit Sales Volume of IndifferenceThe volume of unit sales at which the Martinez Company would be indifferent between the two manufacturing methods is calculated as Sales = Variable Costs + Fixed Costs + Net Income. The value for sales is equivalent to the sales price, $30, multiplied by the number of units sold. Variable costs of $14 for capital intensive and $18 for labor intensive are also multiplied by the number of units sold. Fixed costs were provided at $2,508,000 for ca pital intensive and $1,538,000 for labor intensive.Net income is assumed to be $0. The equation values for 180,000 units under capital intensive manufacturing and 240,000 under labor intensive manufacturing is the volume of units for each method to equal sales of $2,880,000, the point at which the annual unit sales volume would be indifferent.ConclusionEvaluating the costs of manufacturing help management to make crucial decisions about methods of manufacturing that will result in profit for the business. Evaluating the capital intensive manufacturing method versus the labor intensive method provides the values necessary to make business decisions.The circumstances in which the Martinez Company would employ a capital intensive manufacturing method for the new product, based on the numbers provided in the scenario, would be if the contribution margin and per unit cost were cheaper than the labor intensive values. In this scenario, the labor intensive values offer a smaller break-even point value for units and dollars than the capital intensive method of manufacturing.

How the Rising Cost of Fuel Has Affected the Quality of Life

Petroleum well-known as fuel is very useful to our lives. According to Department of Energy, the world consumes nearly 85 million barrels of oil per day. It is completely shows that everybody needs fuel. We use them to fuel cars, airplanes, heater to our home, and to make products like medicines, plastics and materials. The first fuel prices crisis began in 1973, which there was a heavy transfer from the industrialized nations to the oil-exporting nations (Coleman & Cressey, 1990). While in 2004, fuel prices were starting to rise and everything correlated with people and goods has changed. Many factors affect it, such as changes of unfinished oil prices, the transparency of oil markets and rules that affect prices of gasoline (FRES, 2004). In reality, the price of oil has raised would be because of strong contribution by OPEC country, which is Middle-east countries, like Iraq. Whereat, Iraq is one of the fourth highest countries that produce oil to the world. It directly changed the quality to people lives in all over the world. Because fuel is one of natural resources and very important to fulfill people needs. Its effect of gaining will spread in all sectors of countries natural environment. The largest negative influenced part of the rising cost is economy sector. Several industries or companies could not compete without approaching qualified products, because they require lots of energy, raw materials and transportation fees which have strong relationship with fuel. Therefore, those companies planned to raise their product prices so they still can achieve more profits from it and raising the inflation rise. It will also affect the most to some developmental countries. For example, Indonesia as net country importer oil will have negative influences to many industries sectors (Indonesia: Data and Forecasts). Briefly, the raising cost of fuel will eventually influences the economy activity, to the profit or the production of a company and inflation. At last it will affect financial market, exchange rate, country’s finance and the worst is increasing of unemployment. In addition, the raising of fuel means increasing tariff of air transportations, land transportations and water transportations. As reported in some news, British Airways, Lufthansa and Virgin Atlantic airplanes are planning to raise their fare tickets in response of the fuel prices. In fact, transportations are one of the most effected aspects of fuel prices. Every company needs to transport their products to another place, so it will affect to raise the products prices because it cost more for them to delivered products to another place. On the contrary, the high prices of fuel could also stimulate companies to produce more oil. Moreover, when oil price rise, oil companies get even richer which mean they have more weight to trade in. Furthermore in public society, most of citizens have their own cars and fuel become their primary needs. Many people decided to preserve their money on gas since the cost of fuel is increasing. They assumed that if gas prices get higher, they might avoid spending money on other goods and services. Even as some families have a routine, like going to some places on vacation they usually use their cars for long trips and it requires more gas. As a result of the fuel prices, they might prefer to stay at home than to spend money on an expensive fuel. Besides, the increasing of gas prices will affect the prices of their everyday stuff, such as groceries and home appliances. In some way, it is changed people’s lifestyles. As the price of gas goes up, so does the price of a new home. Because, petroleum is the based product for building materials and house equipments, so anything dealing with petroleum is on the rise. Even though the price of gas may change, but they keep build their home. It is a basic need for human being, so they will not get distract of the prices (Mansalle, 2006). Another effect of the changing fuel prices is electricity. Since its raising, people make up their minds to use the electricity less than they usually consume. Several researches reported that a small amount of people feel grateful of the increasing cost of gasoline. They prefer to walk than drive cars with expensive gas prices. Furthermore, it is healthier and avoids people to dependence on personal cars. The rising of fuel prices have forced some students, to change their driving habits. Especially for students who lives far away from their schools, colleges or universities. Meanwhile some students have turned to get on a bus in order to save their money on an expensive fuel. Although the prices of public transportations are rising, but it will still be cheaper. Teenagers are also part of citizens who have affected on the fuel prices. It is going up outrageous and terrifying. They feel dissatisfied and disappointed because it will change their pocket money indirectly. In order to deal with the increasing of fuel, there are some suggestions that might be worthy for government to handle the situation. It is better if government invest in energy alternatives, such as pampetro cars, hybrid vehicles, petrofree cars and ethanol (Madslien, 2006). Pampetro cars only use petroleum. Hybrid vehicle uses petroleum and other sources. While Petrofree cars do not use petroleum, it is 100% electric cars. Ethanol is a type of fuel made from corn hunks which relatively cheap and gives better efficiency. This way, would help keep our environment clean from pollution and help preserve our natural resources. This would also help to increase the production of corn. I think this is the perfect time for people to use public transportations. At the beginning, Government provides public transportations for citizens but people yet still using their own cars. Using public transportations will also help government to generate revenue. Actually, there are some thoughts that might be useful for people to save their money on gas. First, try to drive slower than we usually are. Because drive faster than the speed limit will uses more gas. Second, keep cars in good shape and take good care of it. Last thought, find a car that has the best gas mileage when planning to buy one (Nwazota, 2004). Maybe those opinions will offer some improvements to change people’s bad habits. Indirectly, it will help us to save more money on gasoline.
