How Organisations Use ICT Essay Example for Free

How Organisations Use ICT Essay The Northampton Academy is a new comprehensive school situated on the Billing Brook Road in Lings. There are 1300 students attending this school with the age range of these varying from 11-18 years. Northampton Academy Many business organisations use ICT in different ways depending on the type of organisation and how ICT can improve and help the business. The Northampton Academy is good example of a business that uses ICT in administration, in a more advanced and wider range of ways. The Academy needs to be able to send out letters to parents providing information such as how well their child is doing in school, whether or not their child is displaying the right kinds of behaviour in school, or information on educational trips coming up which their child may be interested in or is a part of. Newsletters also need to be sent out providing the parents of each and every child in the Academy with information about forthcoming events, plans for the future and general information such as school term dates. The variety of ways in which they use ICT in administration, are those such as at times like registration. The register will be taken by the teacher and each student marked present or absent, and then the register will be taken to reception where the staff will then feed it through an OMR (Optical Mark Recognition) machine. This saves time and effort of those that would otherwise have to type in the information of every student, saying whether or not they are present at school that day, so that each pupils attendance is recorded on their systems. With this information the computers will be able to work out each pupils percentage of attendance to put on individual records and also to enable them to keep on top of truancy and report attendance levels to parents. The school has to keep a record of every pupils data on their databases which is all done through ICT and typed into the databases on their computers. These need to be able to be updated if a student has a change of address or a slight change of information. The contact details can be stored easily and found easily which means it is a lot quicker to search for information on each student. It is important for the information to be retrievable quickly because if a child is ill or is in urgent need of going home, then telephone numbers and emergency contact information on that student needs to be found as quickly as possible and the staff dont have the time to be searching through paper files looking for that students information. Some of the information on each pupil is needed to be kept confidential, and because it is all recorded through computers, rather than having to be written out and stored in filing systems, which would take up much more room and time searching for information, it is easier to allow for that to happen. Each member of staff can be put at different levels of access on the administration system and password protection can be enabled to individual records so that only the people that need access to those files can retrieve the information. Student and staff timetabling is arranged through ICT. They are produced through the software SIMs (Schools information management System). The computers store all the information about what year, ability level and lessons each pupil should be placed into and timetables for each and every student can be made. There has to be a teacher present at each lesson so teacher timetabling is also sorted through ICT. This way if there are errors made on an individuals timetable or there is a mix-up somewhere, it doesnt take long to correct it on the systems and re-print another one for the student or the member of staff. Using the software on the computers, things such as sending out newsletters, sending letters home to parents and general word processing becomes a lot quicker and easier. They can be made professional by applying letterheads to each letter they send, and addresses can be mail merged to save time in having to find out names and addresses in manual filing systems. Every so often, each child is issued with a report that informs their parents about how they are doing in school and monitors their academic learning. Instead of each teacher writing every pupils report out by hand, the report is typed out which saves a lot of time. There are templates that teachers can use which, again, saves time in typing out a different report for each and every individual, when sometimes that isnt always necessary. This is all carried out through the use of ICT which is very useful, especially when reports are sent out to every student on a regular basis. Another beneficial way of using ICT in The Northampton Academy is carried out in the finance office. The financial department uses Microsoft Excel software to store information on every area of finance. This programme allows the use of formulae which automatically calculates and updates the changes made in finance so that they can keep track of how much money they are spending. Microsoft Excel provides great benefit to the school when it comes to financing because of this use of formulae. If you need to change a figure, then the spreadsheet recalculates everything again for you, saving a lot of time. The school has a budget which the finance office has to keep track of and make sure they keep to it and not over-spend. To do this each department is allocated a certain amount of money that they can spend over a given amount of time, which they can use to buy resources or other equipment they need in their department area. Another important area the finance office deals with is staff wages. On their systems they keep track of how much each member of staff is being paid, when they need to be paid, and it will update all that information on the spreadsheets whenever a member of staff gets given a pay-rise or any changes are made to their pay. The financial department deals with making sure every member of staff gets paid the correct amounts when they are due for their next pay. The school provide a various number of different educational trips that take place over the school year. The finance office has to keep a system that shows them how much money each pupil has paid and for which trip, and how much more they need to pay. So that the pupil is aware of this also, the financial department issues each individual with a receipt. This information is stored on spreadsheets and every time the pupil pays in a sum of money it is changed on their spreadsheets and totals are automatically updated. The hardware used throughout The Northampton Academy varies depending on whether youre part of the administration team or a pupil at the Academy. This will depend on the workstation used. The station used by the administration team is a Dell OptiPlex GX1. This includes: * 15 or 17 CRT (Cathode Ray Tube) monitor. These are big and bulky and take up more space. The administration staff have more room on their desks in general, because the desk only needs to cater for a single person, so they can manage with having a bigger monitor on their desk. * CPU (Central Processing Unit) * Mouse * Keyboard * Intel Pentium 2 or 3 processor * 265Mb RAM * CD Drive * Windows 2000 The station used by the pupils at the Academy is a Dell OptiPlex GX270. This includes: * 15 TFT (Thin Film Transistor) monitor. These are flat screens, which are small and compact. The students use these monitors because they need more working space on the computer desks as they dont get a desk to themselves, individually. This way more computers and more students can fit into the classroom. * CPU (Central Processing Unit) * Mouse * Keyboard * Intel Pentium 4 processor running at 2.6Ghz * 40Gb Hard Disk Drive * CD Drive * Windows XP Pro The workstations used by the administration team arent as quick and efficient as the ones used by the students. The Dell OptiPlex GX1 has all the hardware needed and is suitable for the needs of those in administration. The workstations used by the pupils have a faster running time with it running at 2.6 GHz. The memory of the computer is larger, to store all the work completed by students. The reasoning behind the students using 15 TFT monitors is so that space in the classroom is used more efficiently and so more students and more monitors can fit into the classroom. This applies to the tower box also. They are small and placed under the computer desk so that the only things on the desk itself are the monitor, the mouse and the keyboard. This allows space on the desk for students to have other things out and have more room in front of them. Each computer has a mouse and a keyboard. These arent cordless, because it avoids the trouble caused if they were misplaced, lost or perhaps, in an extreme event, stolen. In the classrooms, The Northampton Academy uses black and white LaserJet printer and colour Inkjet printer. Inkjet printers spray magnetically charged ink through a fine nozzle onto each sheet of paper, where a LaserJet printer uses a laser beam. The black and white LaserJet printers are used on a more regular basis simply because it is a lot cheaper to run. It prints very quickly and makes them efficient in classes where a lot of pages needed to be printed out by each student. When colour prints are needed, although the colour printers are not used much due to the cost of them and because of the very slow speed they print at, colour Inkjet printers are used because they are a lot cheaper to buy than they would be if colour LaserJet printers were used. The Northampton Academy has Microsoft Office 2003 software installed throughout the school which is used by both students and members of the administration team. The different programs used are: MS Office 2003 MS Word Word Processing Used by the staff to produce letters which can then be sent home to parents. Used by the students for GCSE coursework when typing up essays or producing work in various subjects. Teachers can prepare worksheets to be handed to the students in their class. MS Excel Spreadsheet Used for calculating sums of money in the finance department, and keeping track of school budgets. Used by students for ICT GCSE coursework. MS PowerPoint Presentation Used to create slide show presentations by teachers of various subjects which can then be shown to students to provide them with help and information in specific areas of the subject. MS Access Database Used to store information on every student in the school on a pupil database. Used for mail merging. Used by students for ICT GCSE coursework. MS Publisher Desk Top Publishing Used to produce newsletters which can be sent to inform parents of upcoming events on a regular basis. Used by students for ICT GCSE coursework. MS Visio Diagram Creator e.g. Flow Charts Room Plans MS InfoPath Used to create forms for data capture Microsoft Office 2003 isnt the only software used throughout the school. SIMs is used to a high extent in the administration office. SIMs (Schools information management System) is a full database which: Allows for the producing of timetabling for both staff and students. Produces set lists Is used for pupil monitoring, which are carried out and sent home to parents every 6 weeks using OMR (Optical mark Recognition). Is used for registration. The register is taken and the sheets are read by the optical mark reader machine. The data is then transferred into the database and matched to individual students. From this absence lists can be produced and followed up. The machine can then perform calculations which show attendance percentages for each student. Allows examination entries to be recorded for each, individual student and also produces exam timetables for them. Manages the pupil databases. Each student has a UPN (Unique Personal Number) which they are recognized by. To keep track of the money coming in and out of the school, the department budgets and the whole school budget, the finance office staff use specialist financial software (a database) called Hebron. This manages all the finance information, except from one area due to the fact that Hebron doesnt contain an order tracking system, and so Excel is used for this. As well as the different programs used in various ways for doing various different things, Windows XP offers other software which can be used. File Management Internet Explorer Utilities Paint Notepad WordPad Calculator This allows for the Academy to be fully equipped and use every piece of software they need and will benefit from. ICT is used widely across the school. It is used to a large extent in the ICT department to enable students to learn and complete work using the software on the computers. Every ICT room has a projector to allow for presentations and slide-shows to project onto a screen for the whole class to see and make use of. Cross-curricular use of ICT across the school has become a much bigger thing, which now means that every teacher is receiving a personal laptop; the use of ICT is specified under the National Curriculum and GCSE/A Level specifications; and the school is making use of many mini-suites and classroom PCs and trolleys. Interactive whiteboards are used in various classrooms, and the use of these is becoming larger by the day. The school is able to run more efficiently from the administration side of things as well, thanks to the great use of ICT. Letters can be produced and sent to parents using mail merge with the information retrieved from the pupil information database. As there are 1300 students in the school, the use of standard letters and templates comes in very useful. Clear and accurate information is kept about each student which is easy to find and can be easily updated using the database rather than using a manual filing system, such as lots of paper files. Books for educational purposes can be ordered by using the electronically stored order forms and being filled in using formulae to prevent mathematical errors occurring. The finance office manages the flow of money coming in and out of the school at a much quicker and easier rate because of the use of ICT. They make use of spreadsheets and specialist software in which they type in formulas to avoid repetitive tasks of adding up, calculating the averages and percentages and totalling sums of money, especially in cases where the information has to be changed. To keep the school functioning and communicating effectively, teachers now have Ranger software which allows for them to take over a students workstation from anywhere in the school if they are on inappropriate websites. The teachers can also send or post work straight to the students monitor using this software, which can help students to improve their work and allows for the teachers to monitor each student at any time to observe whether they are working hard. In general, ICT is used massively throughout The Northampton Academy which means the school is benefiting greatly by every aspect of ICT. Already, by the year 2004, the use of ICT in schools is fantastic. And to think that ICT is expanding and improving every day, makes you wonder what the future could hold! Lings Music Ltd Lings Music Ltd is a small independent company situated in the Weston Favell Centre with just the one branch. There are only 7 members of staff who keep it up and running. One of these is the manager and the other 6 are just ordinary working staff. The company isnt tied to any other big music stores; it is just a single, independently run, small company. Lings Music Ltd specialises mainly in pop music, but offers other categories of music. Because this is such a small company, they are unable to afford the latest equipment or any other expensive ICT equipment, so this means they have a limited amount of access to ICT in general. Lings Music Ltd do make use of some ICT but what they do make use of is very small, simply because they dont have the money to buy exceptional ICT equipment, so they make use of the basic hardware and software. The Microsoft package Lings Music Ltd uses is Microsoft Office XP, although they do not make use of all the software provided. They word process the lists of CDs they have in stock; use Microsoft Word or Publisher to produce basic flyers, leaflets, faxes, memos, letters and newsletters which help to promote their small business and advertise a little further. Lings Music Ltd also makes use of Microsoft Excel to calculate the staff wages, tax and National Insurance which saves them having to calculate everything themselves, manually, and instead use the automatic calculations provided through Excel. This saves a lot of time considering the staff number is small. Outlook Express is installed to enable for them to send emails and receive emails, which they can use to promote their business and sales to previous customers. But the main use they make out of Outlook Express is to email their suppliers to place orders to keep their stock at the correct levels. Lings Music Ltd only has one stand alone PC which is used by the manager. This means that it is not networked and if they introduced another PC into their business they would find it very difficult to update, access or share any files through the system. The one computer they do use is a Dell Pentium III with an 800 x 600 14 TFT (Thin Film Transistor) screen equipped with an Inkjet printer. With this all the hardware is used and made use of. Lings Music Ltd has managed to stay up and running as a small independent business for a fair amount of time now, but if they were to ever make the company any bigger and try to promote more and make more sales, then they would experience a lot of problems when it came to networking, the amount of software they use and the amount of PCs they use in their business. The manager and the 6 members of staff who run Lings Music Ltd have managed to get by with the equipment they do use, but could find themselves experiencing problems in the future as ICT expands and improves and they cant afford the latest ICT equipment.

Gender Stereotypes In Advertising Campaigns

Gender Stereotypes In Advertising Campaigns The role of women is more stereotypical than that of the men in the promotional campaigns, and the power of women are inferior to the man especially in the TV advertisements. According to the research on adverts researchers have been done before, the results usually fall into the following categories including: (1) Women being linked with sexual meanings. (2) Women being viewed less powerful than men. (3) Women being thought to be obliged to dominate the housework. (4) Women being believed to comply with their male partners. Over 30 years ago it was argued that advertising placed women into subordinate roles and that the male voice was authoritative (Lewin-Jones, J, Mitra, B. 2009), which is supported by a number of researches. Ferguson, Kreshel and Tinkham (1990) suggested that woman have long been viewed as sexual objects in the advertisements. Dilevko and Harris (1997) stated that in the journals advertisements they researched, females activities are more restrained than males, and men are more likely to gain fame and to be connected with a promising future. Meanwhile, Sexton and Haberman (1974) illustrated that the images of women reflected in advertisements is narrow. All they have to do is to dress up, stand still and being watched. In addition, advertisements also help to cultivate social roles and responsibilities of men and women respectively, in particularly the later ones. The image of women constructed by some established magazines are mostly in conventional occupations and working women profiled in these magazines tend to express themselves by lacking power in their jobs (Ruggiero and Weston, 1985). Simultaneously, Bartsch, Burnett, Diller and Rankin-Williams (2000) argued that Gender bias still exist as females are underrepresented as product representatives for domestic products and males are overrepresented as representatives for non-domestic products. Briefly speaking, these studies show that in the advertisements, women are more inclined to the jobs and titles of housewives while men are more likely to domain in the working field. Moreover, an interesting point has been found out in several of the researches, i.e., in the advertisements, the voice of the spokesmen/spokeswomen can affect the acceptance of the products, which also reflects gender stereotypes. Peirce and McBride (1999) stated that in the commercial advertisements they have studied, more males are used as spokes-characters, and more male spokes-characters are remembered than the female spokes-characters. Media, especially the commercial advertisements of promotional campaigns, do have some strong influence on the construction and cultivation of gender stereotypes, because it helps to reinforce the different roles of man and women in the society and it repeats and retells every day through various channels such as newspapers, radio, bulletin board and TV. In those ads, men are strong and powerful, and they are supposed to save the world, while women are weak and sentimental, and they are set to worship their male heroes. Men should be working outside whilst women should clean the house. Although it is hard to tell whether ads have been affected by the culture or vice versa, it is true that advertisement, as a part of culture itself, do make a difference in constructing gender stereotypes. In fact, gender stereotypes that outstand in the advertisements are not rare. For example, the Mercedes-Benz S Class 8 airbags advertisements. In that advertisement, a woman showing only her breast was being copied four times so that it made eight breasts in one dimension, which compared the breasts as the airbags to symbolise safety and reliability. It is true, to some extent, that this ad is creative enough to stimulate the male audience and to call on their emotional appeals which can turn into actions of buying in the end, but it also used female image, or sexual image specifically, to persuade their targets. As said by Diane Barthel (1988), the beauty rolethe importance of appearing attractive in public, of maintaining standards, of encouraging male attentionbecomes a central preoccupation for girls and mains a concern for women for much of their lives, if not all their lives. Another typical status quo that represents gender stereotypes in the advertising campaigns can be found in one of the channels from Chinese Central Television, namely CCTV5, which is focused on sports news. And it has been years since this channel only broadcast advertisements on mens sports wear, suits, wines, luxury watches and cars. In that channel, ads are made for the males to notice and watch, as are sports programs. If a female audience is watching this channel, she might get a confusing impression that she is not supposed to watch it. Men are born to be sport-oriented, and women are too weak to do intensive exercises. This is blatantly shown in the advertisements that the companies do not even bother to take their female customers into account when it comes to the field of sports and sports competitions. As a matter of fact, this phenomenon has already been studied and by some researchers, and they come up with the conclusion that advertisers made no attempt to appeal female sports market as a separate segments. (Shani, Sandler, and Long, 1992 ) Based on the researches and the examples listed above, it is likely to draw a conclusion that gender role portrayals in ads has been and is still going to be stereotypical for a long period of time(Ivy Backlund, 1994 , as cited by Brasted, M 2010). There might be some new ads showing that females are gaining their own power and are stronger than they used to be, but the mainstream of the promotional campaigns in the market nowadays are still emphasising on the different roles that man and women plays respectively, or on the point that women should stay home and maintaining attractive to men. However, one thing people can not deny is that, the ads producers get their ideas and thoughts from the cultures they have long been lived in, which in return affect the culture itself by influencing the audience who grow up there as well. People can not avoid from the gender stereotype thoroughly because it roots in their lives, but people do can avoid imposing on it by realising the potential effect it will have on them.

Structure And Function Of The Heart Physical Education Essay

Structure And Function Of The Heart Physical Education Essay The cardiovascular system is a very complex and unique system. The main structures of the cardiovascular system include the heart, blood, and blood vessels arteries, capillaries and veins. It is a system that allows all nutrients such as amino acids, electrolytes and lymph, gases, hormones, and blood cells to pass throughout the body, these all aid in the process of fighting diseases, stabilizing body temperature and maintaining homeostasis. Coronary, pulmonary and systemic circulations are the systems that allow blood to be pumped throughout the body, coronary circulation is the system that allows blood to be pumped through the heart, pulmonary circulation is the system that pumps blood through to the lungs and the systemic circulation which is the system that pumps the blood around the rest of the body and to the remaining organs. As humans we have a closed cardiovascular system which means the blood never leaves the circulation of the blood vessels. The coronary circulation is part of the systemic circulation by definition it supplies blood to muscles- muscles of the heart (myocardium), however it is the only system to provide the heart with blood. The blood comes from the aorta and filters through into the right atrium. If the heart didnt receive the blood supply, it would cause severe tissue damage. The pulmonary circulation uses the pulmonary artery to take de-oxygenated blood away from the heart through to the lungs which is where the blood is then oxygenated. The de-oxygenated blood enters the right atrium of the heart and flows through the tricuspid valve and then from there it flows into the right ventricle, here it is then pumped through the pulmonary semilunar valve into the pulmonary artery to the lungs. In the lungs is where the gas exchange takes place, where the CO2 is released and the blood then absorbs oxygen. This is the stage when the pulmonary vein returns the freshly oxygenated blood to the heart. The systemic circulation on the other hand takes the oxygenated blood from the heart and transports it throughout the rest of the body except from the lungs. The system then provides all other organs with the oxygenated blood, the circulation then returns all of the de-oxygenated blood back to the heart for the process to start all over again. The systemic circulation is a much lengthier system than the pulmonary circulation due to transporting blood all over the body. (1)The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle. The right atrium is the upper chamber of the right side of the heart. The blood that is returned to the right atrium is deoxygenated (poor in oxygen) and passed into the right ventricle to be pumped through the pulmonary artery to the lungs for re-oxygenation and removal of carbon dioxide. The left atrium receives newly oxygenated blood from the lungs as well as the pulmonary vein which is passed into the strong left ventricle to be pumped through the aorta to the different organs of the body. The blood circuit is flows in the shape of a figure of 8. There are two loops to this circuit. The top loop carries the blood from the heart to the lungs and back (the pulmonary circulation). The bottom loop carries the blood from the heart all over the body (systemic circulation). The 4 main stages of the cardiac cycle are: Atrial Diastole -which is where the top chamber (atria) relaxes and fills with blood from the veins Atrial Systole- where the atria contracts and blood is forced into the relaxing bottom chambers which are otherwise known as ventricles Ventricular systole- which is where the ventricles contract and blood is forced out of the heart in to the arteries. Ventricular diastole -when the ventricles relax and become ready for the next pump cycle. The circulatory system also consists of the lymphatic system; this is a non-closed system that carries a clear liquid called lymph towards the heart and allows an average of 20 litres of blood per day through capillary filtration which removes plasma while leaving the erythrocytes. Around 17 litres of filtered plasma get reabsorbed into the blood vessels; however 3 litres are then left behind in the interstitial fluid. The main role of the lymph system is to provide an auxiliary route for the extra 3 litres to return to the blood. (4) The lymphatic system has multiple interrelated functions: it is responsible for the removal of interstitial fluid from tissues it absorbs and transports fatty acids and fats as chyle from the digestive system it transports white blood cells to and from the lymph nodes into the bones The lymph transports antigen-presenting cells (APCs), such as dendritic cells, to the lymph nodes where an immune response is stimulated. There are three main blood vessels in the cardiovascular system, these are the arteries, veins and capillaries; arteries are responsible for carrying the blood away from the heart, they are made up of a thick elastic muscular wall, which is capable of stretching as blood is being pumped through at a high pressure. The muscle walls are able to contract to force the blood along through the arteries. Veins are made up of a much thinner, less muscular wall compared to the arteries. The blood in the veins is under considerably much lower pressure compared to the blood in the arteries, this is because arteries need higher pressure in order to deliver the oxygenated blood to the arterioles, capillaries, other organs and tissues and to also prevent the back flow of blood, veins dont require this high pressure because the de-oxygenated blood can travel from the tissues to the heart through the veins with the help of the muscle contractions. One of the functions of the veins is to ensure that the blood doesnt flow back towards the heart, veins contain valves every few centimetres along, this helps them push the blood in one direction. However muscle contraction and relaxation can also occur to help squeeze the walls of the veins to help the blood flow back towards the heart when necessary. You can use a stethoscope to hear pulmonary circulation. The sounds that are audible are the ventr icles contracting and the valves closing. Capillaries are the smallest of all the blood vessels they have a wall that is one cell thick, capillaries connect the arterioles and venules this is where all the exchange of nutrients and gases such as oxygen and carbon dioxide occurs- through the capillary surfaces. Leucocytes are able to leave our capillaries in order to digest any micro-organisms that could be a potential threat or disease. Arteries, veins and capillaries are all blood vessels of the body and all of them are routes for the blood to pass through to provide their functions. They all contain tunica externa, tunica media and tunica intima. Blood is carried away from the heart via the arteries and the blood returns to the heart through the veins. Our circulatory system is a transport system the carries our blood, oxygen and waste products to and from our bodys cells in order for our bodies to functions. (2) During systemic circulation, blood passes through the kidneys. This phase of systemic circulation is known as renal circulation. During this phase, the kidneys filter much of the waste from the blood. Blood also passes through the small intestine during systemic circulation. This phase is known as portal circulation. During this phase, the blood from the small intestine collects in the portal vein which passes through the liver. The liver filters sugars from the blood, storing them for later When it comes to heat regulation in order to keep cool our capillaries are capable of forcing the blood supply to the surface of the skin, this allows the air to reach the blood and to cool it more easily, and sweating is also induced as part of the heart regulation. However when trying to keep warm our capillaries work hard in order to reduce the blood at the skin surface and sweating is also reduced. This is known as vasoconstriction and vasodilation. Heat regulation is one of the key functions of the circulatory system as well as many other functions. Signals along nerves from the hypothalamus control both vasodilation and vasoconstriction. It is necessary for the human body to have vasodilation and vasoconstriction as it regulates the bodys blood pressure, by constricting and releasing the vessels to allow more or less blood through, for example whilst exercising our heart and breathing rates increase and blood vessels in our limbs dilate in order to deliver more oxygenated blood to our working muscle cells. (3) Vasoconstriction is the narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels, particularly the large arteries and small arterioles. The process is the opposite of vasodilation, the widening of blood vessels. The process is particularly important in staunching haemorrhage and acute blood loss. When blood vessels constrict, the flow of blood is restricted or decreased, thus, retaining body heat or increasing vascular resistance Our blood that is carried around in our cardiovascular system is responsible for maintaining its levels in many advance ways. For example haemostasis is a complex chain reaction that produces the blood to clot this is otherwise known as coagulation. The body clots in two different ways, there is the normal clot which is a good formation that stops bleeding, and there is also a thrombus which is bad as it can block the blood vessels. The endothelium is the cells that create the vessel wall. When the endothelium becomes damaged, for example, when a cut breaks through the wall, collagen fibres then start to appear. These collagen fibres are a protein that is vital for the structure of the vessel wall, these fibres then allow platelets to attach themselves, these are produced from precursor megakaryocytes, its these platelets that lead to the formation of blood clots. The platelets become activated and begin to release a chemical called Thromboxane A2 which calls on more platelets to the area. Fibrin, which is the insoluble form of the soluble protein fibrinogen, is then converted by thrombin. The fibrin begins to appear and layers on top of the platelets which start to fuse them together. This fibrin helps the clot form as the red blood cells stick to the fibrin. This process then repeats until the clot is fully formed. This process is important for the cardiovascular system, this is because the average human contains around 4.7 to 5.7 litres of blood, if around 30%-40% of this is lost it could prove fatal or cause severe damage. The blood the is carried around the cardiovascular system, is made of erythrocytes, leucocytes, platelets and plasma which is mainly water, amino acids, proteins, carbohydrates, lipids, hormones, vitamins, electrolytes, dissolved gases, and cellular wastes. Erythrocytes contain a globular protein called haemoglobin which allows oxygen to bind to it; this allows the erythrocytes to transport oxygen throughout the body and organs. The haemoglobin molecule is made up of 4 polypeptide chains, 2 containing 141 amino acids and 2 containing 146, attached to each polypeptide chain is a molecule that contains iron and is known as a haem, the function of this molecule is to absorb oxygen until it is fully saturated. Carbon dioxide however binds to the amino acids and not the erythrocytes, this means that is binding to the proteins and not the haem.

Imagery in Lycidas Essay -- Poetry John Milton

Imagery in "Lycidas" "Lycidas," a poem written by John Milton as a memorial to Edward King, a classmate at Cambridge, reflects Milton's reverence for nature, his admiration of Greek Mythology, and his deeply ingrained Christian belief system. In "Lycidas," Milton combines powerful images from nature and Greek Mythology along with Biblical references in order to ease the pain associated with the premature death of King. King drowns at sea in the prime of his life and Milton is left to make sense of this tragedy. Milton not only mourns the loss of a friend; he is also forced to face his own mortality. Milton questions the significance of writing poetry when he will inevitably die. Milton copes with the subject of death by insisting on the glory of a Christian life and the promise of rebirth into the joyous spiritual world of heaven after death. Milton begins "Lycidas" by introducing Mythical imagery. Milton writes, "Yet once more, O ye Laurels, and once more/ Ye Myrtles brown, with Ivy never sear" (1-2). In the poem Laurels refers to the crown of poetry given by Apollo, while myrtle refers to the Greek goddess Venus, and Ivy to the god Bacchus. Then Milton introduces powerful symbolism derived from nature. He writes, " I com to pluck your Berries harsh and crude, / And with forc'd finger rude, (3-4). Milton is first alluding to the forced and premature writing of his poetry in the memorial to his classmate Edward King. Secondly, he is perhaps alluding to the premature and violent death of his classmate. In the passage King is the "Berrie" that has been "plucked" before it is ripe or mature. The "Berrie" (King) is "plucked" with "forc'd finger rude," which suggest some degree of violence in his death. It seems that this passa... ... in the glory of heaven. King's spirit will live on. King is the, "Genius of the shore" (184). In "Lycidas" Milton speaks through many voices. From Greek Gods to Biblical figures, Milton shields his voice and personifies these figures who address the subject of death in a less worldly language. This method of writing not only demonstrates Milton's broad education, it also serves to lighten a heavy subject. Shielded by Mythology and motivated by the optimism of Christianity, one can approach the subject of mortality with hope and give meaning to life. Without hope this subject would most likely force the reader to spiral down into deep despair. Bibliography Flannagan, Roy. Ed. The Riverside Milton. Boston: Houghton Mifflin Company, 1998.

Andrew Marvell’s To His Coy Mistress and John Donne’s Flea Andrew Marvell and John Donne both wrote â€Å"carpe diem† poetry full of vivid imagery and metaphysical conceits. This message can be clearly seen in the poems "To His Coy Mistress" by Marvell and Donne’s "Flea." Though both poems take a similar approach to the topic addressed, it is Marvell that writes more thoughtfully and carefully, coercing instead of Donne’s seemed demanding\begging. The speaker in â€Å"Coy Mistress† is trying to convince his woman of choice that it is much better to have sex now than to save her virginity for the future. Why save it until they are married? The man wants to experience the pleasure now. Marvell’s message here seems to be that instead of worrying about the future; planning exactly when we should do things, humans should take things as they come and enjoy them before it is too late. This theme relates to all aspects of life, not just sex. Donne’s narrator, though having the same goal and idea, is far more blunt in his reasoning. Noticing a flea that presumably had bitten them both, he ar...

Assignment on the Contribution of Charles Babbage, Adam Smith and Robert Owen in the Field of Management Essay

Contribution of Charles Babbage in the field of Management Charles Babbage (1792–1871) is known as the patron saint of operations research and management science. Babbage’s scientific inventions included a mechanical calculator (his â€Å"difference engine†), a versatile computer (his â€Å"analytical engine†), and a punch-card machine. Babbage’s most successful book, On the Economy of Machinery and Manufacturers, published in 1832, described the tools and machinery used in English factories. It discussed the economic principles of manufacturing, and analyzed the operations; the skills used and suggested improved practices. He showed that reducing the tasks of manufacturing to their simplest activities increases the numbers of people who can do them and, thus, reduces the average wage which needs to be paid. According to him, a work should be divided into mental and physical efforts and a worker should be paid a bonus in proportion to his own efficiency and success of the business. Babbage emphasized the importance of division of labor, indicating that greater profit could be made by specializing. Babbage also emphasized the importance of balance in processes and the principle of optimum size of the manufacturing unit for each class of product. Contribution of Robert  Owen  in the field of Management Robert Owen (1771–1858) was a successful Scottish entrepreneur and a utopian socialist who sowed the first seeds of concern for the workers. He was repulsed by the working conditions and poor treatment of the workers in the factories across Scotland. Owen became a reformer. At New Larnark, in his factory he was trying to make different approaches to the workers. He reduced the use of child labor and used moral persuasion rather than corporal punishment in his factories. He chided his fellow factory owners for treating their equipment better than they treated their workers. In 1813 he proposed a factory bill to prohibit employment of children under the age of ten and to limit hours for all children to 103/4 hours per day with no night work. The bill became law six years later, but was limited to cotton mills, reduced the age limit to nine, and included no provision for inspections; therefore, the law had little impact. Owen was totally devoted to management as a profession. Under his direction, houses and streets were built, the minimum working age for children was raised, working hours were decreased, meal facilities were provided, schooling were introduced, and evening recreation centers were opened to meet the problem of leisure. He is the father of modern Personnel Management. Contribution of Adam  Smith  in the field of Management Adam Smith (1723–1790) was a Scottish political economist. His Wealth of Nations, published in 1776, established the â€Å"classical school† and with its publication, he became the father of â€Å"liberal economics. † Smith argued that market and competition should be the regulators of economic activity and that tariff policies were destructive. The specialization of labor was the mainstay of Smith’s market system. According to Smith, division of labor provided managers with the greatest opportunity for increased productivity. He gives three reasons for the increased output due to the division of labor: a) to the increased dexterity in every particular workman b) to the saving of time which is commonly lost in passing from one species of work to another c) to the invention of a great number of machines which facilitate and abridge labor, and enable one man to do the work of many. His idea about the division of labor is fundamental to modern work simplification and time study, and extends also into such areas as production simplification.

Buffalo film review

Do you want to fragrantly waste a mind-numbing hour and a half of your monotonous life? If you just threw you hand up in the air and shouted yes', then Vincent Gallon's film Buffalo '66 is for you. You will be subjected to a remarkably mundane plot, which will leave you hopelessly confused and a little afraid. It's only rendering feature is, perhaps, the artistic style in which it is created. The film Is set In the overly Industrialized town of Buffalo where our mall character, Billy Brown. Who Is played might say, badly by Gallo himself, was born with regret ND raised with disinterest.We are fist introduced to Billy as he is being released from prison. We become reluctant voyeurs of his life. His first problem that he had to face after being released is searching for a bathroom. Yes! You real that right. For the first maybe 20 minutes of the film, he is running around in his bright red boots, and ill fitted clothes, looking quite Like a child holding his genitals searching for a pla ce to relive himself. I really don't understand the meaning of this either. But what an entrance to a movie. Throughout his hunt for a restroom, we are introduced to Lay.Gallo has decided to put her in a virgin blue dress, a doll like face and alienated from the rest of her dance class. In fact she looks very much like a prostitute. Gallo chooses to sexuality her, focusing the camera around her breasts. Maybe this is why Billy kidnaps her. Yes! I said kidnaps. Told you this was a weird movie. Well Billy makes Lay drive him to his parents house, because he can not ‘drive a stick, but along the way he makes her pull over so he can relieve himself behind a tree. Any normal person would have Just driven off and got the hell out of there. ButLay is not normal, she is alienated from society because of her lack of lets call it social skills. She decides to stay, and continue being kidnapped. Apparently his playground talk of ‘If you do this for me, I will be your best friend, y ou will be the best friend I have ever had'. However if we gallantly ignore this entire aimless and dreary plot all we have left is Gallon's amazing use of techniques such as his use of colors, music and camera angles. Throughout Buffalo '66, Gallo focuses on the abundant use of pale colors and lurid scenes, which portray a lonely sense of emotion and feeling.Gallo an accomplished musician composed a very suitable score to accompany the film. Having himself creating most of the songs Gallo was able to carefully control a great deal of the mood and feeling of each scene. His song ‘Lonely Boy playing at the start of the movie in the opening credits, starting when the Billy Picture is shown Is a good example of child in the picture. Another technique is Gallon's use of overlaying images or videos over the top of the already playing film. He does this to show flashbacks to inform us of Billy's past. Through these flashbacks we discover that Billy's childhood was very harsh.We see his loss of innocence through his Fathers anger on his dog Bingo, and his Mothers lack of care when Billy has an allergic reaction to chocolate. We also see his innocence in the events that sent him to prison. With Billy's Mothers obsession with the town's local football team the ‘Buffalo Bills', we see her lack of care in Billy as a child again. When Lay asks Billy's mum to see a photo of Billy as a child, She then replies to husband â€Å"Where's the Billy Picture? † He had one picture as a kid, ONE!! But as you walk into the house you see a bunch of pictures of Buffalo players.This is a major key to Billy's alienation. He didn't have a normal home and was treated like he wasn't wanted. You will quickly grow tiered of Bill's need to constantly repeat everything he says. You will find yourself getting frustrated and wishing you could somehow reach into the film and bring him to his senses, perhaps by rearranging his facial features. In the bowling ally scene we notice we see Billy and Lay in the photo booth, â€Å"Spanning time† together, Just â€Å"Spanning time†. At this point I found my self shouting at the screen telling him to Just â€Å"shut up†.One important event in the film is the scene between Billy and Lay in the hotel room. We witness them laying on a bed together and Billy looks very, well, uncomfortable, while Lay looks like she has been in this type of situation many times before. We have a bird's eye view of this whole scene so we see every movement that is made. Slowly, very slowly Lay's hand moves towards Billy's, leaving them awkwardly holding hands, well touching hands. After what seems like an incessant amount of time, Billy rolls over, out of his very what must be uncomfortable position and him and Lay kiss. KISS!You heard me right. I thought it was Lay's imagination to be honest. If you think it couldn't get more awkward he curls up in the fetal position in Lay's arms. WEIRD! But this does portray Billy 's childlike behavior again and his need for affection that his parents lacked to provide for him. I think I was thankful at this point in the movie though, because finally, finally, they ended up together. They are not alone anymore, because they have each other. Bit click ©, but never mind that. If forced to offer a quick summery of the film, I would answer in a forceful honesty, hat it is Just plain boring.So bleak and uneventful is the plot, that I would rather go bird watching. It's only rendering features is Gallon's cinematic techniques. There, in my view, are the movies great strength and manage to Just salvage it from complete ruin. So masterful is Gallon's use of cinema that I should recommend this film to English school teachers and others that appreciate the subtle and obscure artistic works. To the rest of us, I would issue a warning to avoid the film, like stay at least give it 5 stars out of 10.
