Thermodynamics of the Dissolution Borax

Thermodynamics of the Dissolution of Borax Lina Jawadi Objectives: * Study an arrangement of salt and water arrangement. * Determining an assortment of significant thermodynamics amounts from the solvency data at different temperatures. Foundation: The salt and water arrangement in this analysis has generally basic dissolvability balance of borax in water. Na2B4O7 . 10 H2O 2Na + B4O5(OH)42-+ 8H2O This response is a harmony procedure and 8 water particles from the hydrated salt are lost to the response medium. The harmony consistent articulation for this response is:K = [Na+]2 [B4O5(OH)42-] [H2O]8 [Na2B4O7 . 10 H2O] In this test we will consistently ensure there is some strong borax staying in the example blend before expelling some of it to break down it. In this manner, we can accept that the convergence of strong borax is steady. Likewise, the water atoms which were initially part of the borax’s crystalline grid is lost to the example blend; be that as it may, it doesnâ€⠄¢t altogether influence the convergence of the water. The balance steady articulation would now be able to be disentangled to become: K = [Na+]2 [B4O5(OH)42-]The first harmony articulation and the fair dissolvability balance response permit us to communicate either borate particle or sodium particle as far as the other. In this way, it is conceivable to decide the steady as far as either particle. In the wake of subbing borax particle instead of the sodium particle, ([Na+] = 2 [B4O5(OH)42-] , K = (2 [B4O5(OH)42-] )2 * [B4O5(OH)42-] ) we get: K = 4 [B4O5(OH)42-]3 . Finding the grouping of borate particle in any example at some random temperature gives us the solvency item at that temperature. Hardware: * 5mL pipet * Test tubes * Marker * Hot plate * 250 mL container * Flask Electric equalization Procedure: 1. Utilizing the pipet add 5mL of refined water to 10 test tubes. 2. Imprint the level with the marker and spill the water out. Imprint the test tube with the doled out temperatur e. 3. Gauge 30-32g of strong sodium borate decahydrate (borax) in a 250 mL measuring glass and afterward include 150 mL of water. 4. Spot the blend on a hot plate, yet don’t permit its temperature to surpass 50oC. 5. After all the borax breaks up, include more and let the temperature arrive at 45oC. 6. When it begins marginally surpassing 45oC, expel it from the hot plate and spot rather a container loaded up with 150 mL of refined water. . Keep mixing the blend until it arrives at the ideal temperature. 8. Rapidly pour 5 mL of the blend in two test tube without moving any strong borax. (record the temperature when the exchange. ) 9. At the point when the water shower arrives at 45oC, place the test tube in it until precipitation of borax has broken up. 10. In a cup with 50-75 mL of water and 10 drops of bromocresol green pointer, include 125 mL of the borax arrangement. 11. Before titrating the borax with corrosive ensure that it has a blue color.Using buret loaded up with 5 0 mL goodness HCl, add the corrosive to the borax until it arrives at the endpoint, which is the point at which the arrangement abandons a blue shading to a yellow. Record the underlying and last volume. (For counts: discover the moles of borax utilizing the volume of HCl and its molarity. At that point discover the dissolvability item consistent and plot the ksp versus (1/t) diagram and from it acquire the estimations of ? H and ? S. Ensure the temperature is in kelvin while doing the counts. At long last, discover the estimation of ? G utilizing the two conditions and plot the ? G versus time diagram. )

What are Balloon Payments

What are Balloon Payments What are Balloon Payments? What are Balloon Payments?Don’t let your loan blow up in your face.Balloons are wonderful, aren’t they? While adults may understand that balloons float because they are filled with a gas that is lighter than air, to children, balloons might as well be magic. Children love balloons, even after they realize they won’t be able to fly with them no matter how many they hold at once.Unfortunately, as we age, not only do we begin to understand how balloons work, but it may come to light that there are some dangerous balloons out there. These dangerous balloons include hot air balloons and balloon payments. However, today we will only be talking about one of these: balloon payments.Balloon paymentsA traditional amortized or installment loan is structured so the borrower pays off part of the principal (or original amount borrowed) and interest in regular, consistent amounts. That means the borrower will be able to pay off the entire loan in a known time frame without any surprises. Ball oon loans are different than traditional amortized loans.“Instead of fixed monthly borrowing payments that gradually eliminate debts and establish credit, balloon loans are paid off with large single payments when a loan has reached maturity,” warned Beverly Friedmann, content manager for ReviewingThis.These are called “balloon payments” because the last payment is inflated relative to the previous payments the borrower has been makingâ€"significantly inflated, as Friedmann explained. “Balloon payments are typically at least twice the amount of a loans prior regular payments,” she said. “They can apply to mortgages, business financing, commercial loans, and other types of amortized loans (i.e. auto payments).”Risky businessIt is vital that you know if you will be facing a balloon payment at the end of your loan payments so you can have enough money set aside to pay for the increase. However, even if you did have the foresight to set aside money, you might still end u p in trouble.“The greatest risk with balloon mortgages is that the property goes down in value, rather than appreciating,” said Brian Davis, co-founder of SparkRental.com. “In that case, the borrower often can’t refinance or sell without taking a loss.”While mortgages with balloon payments may have better initial rates, the risks should not be underestimated.Consider your optionsBrain Davis made it quite clear that you are going to want to avoid balloon payments if possible: “Unless borrowers know for a fact that they will be selling the property within the balloon period, I recommend they avoid balloon mortgages and take out a 15- or 30-year fixed mortgage.”What other options could you consider? Here are a few possibilities.Selling your home: “Selling whatever property was loaned (i.e. a home, car) is another option prior to an impending balloon payment if you dont have the funds to cover it,” Friedmann advised. “In the case of homeownership, this is often to av oid foreclosure and/or filing for bankruptcy.” However, the housing market may help to determine if this is a wise option. “This can be a difficult process if the housing market has changed since you invested in your property, and you may find yourself making less than what you paid into it in the first place.”Refinancing: “If youre in good financial and credit standing, you may decide to refinance your balloon payment by taking out another loan,” Friedmann said. “This new loan may add several years to your repayment structure plan, allowing you some time to restructure your finances into a more feasible and longer term payback system. You might even refinance a home loan into a long term mortgage. The only drawbacks to refinancing is that your interest rates might rise, and you wont be able to utilize this option without good credit, income, and assets.”Wait on buying: It might be worth holding off on buying a home for now. While you may have been told that renting is equivalent to throwing your money away, this is not necessarily the case. Homeownership comes with many unexpected costs, so if you are not certain that you will be staying in the home for a long time, then it is probably smart to rent for now.The American DreamOwning a home has long been part of the American Dream, and there are a lot of mortgage brokers who are willing to take advantage of the desire for a home to stick you into a loan you can not manage. Always do your research and consult whichever experts you can before you lock yourself into any financial commitment, especially if it is as large and lengthy as a mortgage.ContributorsBeverly Friedmann  works as a content manager for the consumer website  ReviewingThis,  has a background in sales and marketing management, and is from New York, NY.   Find more information on Twitter  @ReviewingThis.G.

How Graduate School Is Different From College

The first days of graduate school go by in a blur for most new students. Even if you attend the same university as you did as an undergraduate, the graduate school experience is very different from being an undergrad. Is grad school harder than college? Definitely. Coursework Is Just the Beginning Classes are a big part of masters programs and the first couple of years of doctoral programs. But grad school entails more than completing a series of classes. You will take courses during the first couple of years of your Ph.D. program, but your later years will emphasize research (and you probably wont take any courses during those later years). The purpose of grad school is to develop a professional understanding of your discipline through independent reading and study. The Apprenticeship Model Most of what you learn in grad school will not come from classes, but from other activities such as  conducting research and attending conferences. Youll choose  and work closely with a faculty member on his or her research. As an apprentice of sorts, youll learn how to define research problems, design and carry out research projects to test your hypotheses and disseminate your results. The end goal is to become an independent scholar and devise your own research program.  Ã‚  Ã‚   Graduate School Is a Job Approach grad school as a full-time job; its not school in the undergraduate sense. If you soared through college with little studying, youre in for a big culture shock as a grad student  The reading lists will be longer and more extensive than youve encountered in college. More importantly, youll be expected to read and be prepared to critically evaluate and discuss it all. Most grad programs require that you take initiative for your learning and demonstrate a commitment to your career.   Graduate School Is a Socializing Agent Why is graduate school so different from undergrad? Graduate training teaches you the information and skills that you need to be a professional. However, being a professional requires more than coursework and experiences. In graduate school, you will be socialized into your profession. In other words, you will learn the norms and values of your field. Relationships with faculty members  and other students are important to your career, and youll make them in grad school. Most importantly, you will learn to think like a professional in your field. Graduate school shapes the mind and leads students to think in new ways. You will learn to think like a professional in your field, whether a scientist, historian, educator, philosopher or practitioner. It truly prepares you to immerse yourself in a specific field — especially if you choose to become an academic professional in the long run.

We will write a custom essay sample on Electronics or any similar topic only for you Order Now Secondly I would try to complete my assignment under the chosen time limit which is very vital. Thirdly all the given tasks should be completed with appropriate information and try to stay within the word count. Lastly, I would try to present my work with clarity and rationality so my hard work should be understood in best possible manner TASK 1: THE 555 TIMER IC. 1a) Before 555 timer came to the market there were large distinct circuits used to carry out the operation of a timer but the compatibility and numerous other advantages of a 555 timer lead the breakthrough .The 555 timer is an integrated circuit designed by Hans R. Camenzind and commercialized by that times leading semiconductors manufacturer signetics. It’s mainly used in variety for timing purposes, producing perfect timing periods through a vast range of time and as a multi vibrator and due to the versatility of the IC it has made conspicuous place in the history of electronics. Never thought by its maker to be so flexible the 555 package consists of numerous transistors, diodes and resistors (depending on the purposes) imbedded on a silicon chip and connected to an 8-pin dual in line package. (D C Green, Electronics 4, third edition, 1995, Longman Scientific and technical) The single 555 timer chip in its basic form is a 8 pin chip consisting of 20 transistors, 2 diodes, 15 resistors. (http://www.electronics-tutorials.ws/waveforms/555_timer.html )feb 10, 2011 Above shown fig shows 8 pins which are labeled to show there function. Below is the more detailed function of these pins. Pin no. 1: It is connected to GROUND which connects the 555 timer to the negative 0v supply rail. Pin no. 2: It is the trigger pin. A negative pulse on this pin â€Å"sets† internal flip-flop and start up a timing cycle. Pin no. 3: is an output pin of the 555 timer, it can be connected directly to the inputs of other digital IC’S with the required voltage. Pin no. 4: is the RESET pin which is used to reset the internal flip-flop controlling the output. In other words to terminate the timing cycle. Pin no. 5: is a control voltage pin which can be used to alter the timing aspect of the 555 IC in applications such as frequency modulation. Pin no. 6: is the threshold pin which donates the duration of the timer to ‘output voltage in each of the on/off cycle’ this time phase end when voltage at threshold becomes higher than control voltage pin. Pin no. 7: is a discharge pin which is connected directly to the internal transistor which is used to discharge the timing capacitor to ground. Pin no. 8: is connected to the power supply and the range of voltage depends on the appliance need. MODES: After discussing above the different functions of 555 timers, let’s now discuss about its modes, its usage in different modes. 555 timers IC’s can be used as a multivibrator in three different forms they are as follow: Astable mode Monostable mode Bistable mode ASTABLE MODE: Astable means without a stable state. It has two unstable state means 0 and 1, in other words it continually switch it states to high and low creating a rectangular wave form on its output. There are numerous advantages of this circuit few of them in which it is used are flash lights, LED’S, and security alarm. FIG 2 (http://www.kpsec.freeuk.com/images/flashlcd.gif FEB 10, 2011) FIG 3 (http://www.antonineeducation.co.uk/Electronics_AS/Electronics_Module_1/topic_11/topic_11__555_timer_circuit.htm FEB 10, 2011) For the waveform above we can see how it changed from 0 to 1. For this circuit to become operational we need to consider some of the formulas ‘’The mark time [t(H] is the time at which the output is a 1. t(H)= 0.7(RA + RB)C The space time [t (L)] is the time at which the output is a 0. t(L) = 0.7 RBC The mark to space ratio = mark time ? space time. The astable period T is the time taken for one complete cycle, the mark and the space times added together. T = mark + space = t(L) + t(H). The frequency = 1 ? period. f = ____1.4_____ (R1 + 2R2)C The time t (H) will be longer than t (L), unless R1 is very small compared to R2. If this is the case, then t (H) will be approximately equal to t (L), but not quite equal. We can say to a first approximation that the mark to space ratio is 1. This will result in a square wave output’’ ( http://www.antonine-education.co.uk/Electronics_AS/Electronics_Module_ 1/topic_11/topic_11__555_timer_circuit.htm FEB 10, 2011 MONOSTABLE MODE: Monostable means circuit which has only one stable state, normally it has two states means stable and unstable. When the voltage is not applied it remains in stable state but as the â€Å"trigger† is pressed it creates electric pulse and switches from stable state to unstable state and remains there for a limited time period which is set and after that it comes back to stable state. This type of circuit is ideal for â€Å"push to operate† system for a model displayed at exhibitions. A visitor push the button to start mechanism of choice and it automatically switch off after a set time. FIG 4 (http://www.antonineeducation.co.uk/Electronics_AS/Electronics_Module_1/topic_11/topic_11__555_timer_circuit.htmFEB 11, 2011) The above diagram shows the circuit of monostable 555 timer. This circuit operates when the switch is closed and released, the voltage at Pin 2 goes up to down and then up. Due to this Pin 7 is discharged from zero and the voltage increases at output. When the voltage across the capacitor (C) gets two third then the output stop and it comes to stable state. The output of this circuit is shown in the FIG below. FIG 5 (http://www.antonineeducation.co.uk/Electronics_AS/Electronics_Module_1/topic_11/topic_11__555_timer_circuit.htm FEB 11, 2011) BISTABLE MODE: Bistable has two stable states, in this mode 555 timer acts as a flip-flop. You read "Electronics" in category "Essay examples" In this the trigger (which is Pin 2) and reset (which is Pin 4) both are at high state because of the resistors, while the threshold (which is Pin 6) is simply grounded. By taking the trigger LOW it switches to SET position and the output state changes to HIGH and by taking the RESET Pin LOW it switches to reset position and the output will remain LOW. TASK 1(B): A 555 timer is basically used in our daily life as a day/light alarm which can be useful for waking us up from our sleep. Fig 6 http://www.free-circuits.com/diagrams/n/14qwe.gif (March 20, 2011) The components which are used in the above diagram are as follows: 1 Light Dependant Resistor (LDR) 1 transistor 2 set of capacitors both value of 0.01 ?F 1 555 timer 1 diode 15v/1 µF 3 set of resistor range of 10k, 56k and 3.3 k respectively 1 100k variable resistor 1 speaker 8ohm, 0.5W OPERATION: This above circuit exclusively depends on the light for it to function. A 555 timer is used above and it works on a principle of astable mode with frequency of 1Khz. The transistor is set high because of the changeable resistor when light doesn’t fall on the LDR therefore causing the 555’s reset pin low. Just because of this the timer is reset. It resistance decrease when the light falls on LDR which in turn causes a decrease in base resistance of the transistor alloying current to flow. This will cause the reset pin on the 555 timer to increase and allows the timer to ‘oscillate’ and the speaker starts working by creating sound. TASK 2: INTRODUCTION OF FET TRANSISTOR: The field effect transistor is a semiconductor device; it depends on its operation to control current by an electric field. FET’s are available in two basic forms and they are: Junction gate field effect transistor (JFET) Insulated gate field effect transistor (IGFET) But the most commonly used transistor is Metal-Oxide semiconductor field effect transistor (MOSFET). It is commonly used because it can be connected as resistor and capacitor, it is cheaper than Bipolar junction transistor (BJT) , it is much smaller in size and there power consumption is much smaller. CONSTRUCTION AND OPERATION OF FET Metal-Oxide semiconductor field effect transistor (MOSFET) is a type of semiconductor which uses three connections which are GATE, SOURCE and DRAIN. The effective width of the channel is controlled by a charge which is placed on gate electrode. The shape of a transistor is like a bar with P-type silicon and two strips which are doped to make N-type material when the metal is deposited to make two terminals DRAIN and SOURCE, then the surface is covered with silicon-oxide which is non-conductor. Then again metal is deposited to form one more terminal called gate which is shown in fig 1. http://www.interfacebus.com/JFET-N-Channel-symbol.png (March 20, 2011) After it is completed then the potential of (0V) is applied between the source and drain because of P-N junction there is no current flowing. The P-type material which is source terminal is at 0V, and the gate is already made positive so that it will repel the holes from P-type and turn it temporary N-type. This creates a channel joining two N-type strip so that current flow from drain. If the potential against gain terminal is greater, than the channel will become wider which ends with large current. So to conduct this type, positive voltage is applied to gate. http://www.circuitstoday.com/wp-content/uploads/2009/08/n-channel-de-mosfet-structure.jpg (March 20, 2011) Metal oxide semiconductor field effect transistor (MOSFET) is operated in two modes they are: Depletion mode Enhancement mode DEPLETION MODE: Regardless of weather a MOSFET is N-type or P-type material but there are still fundamental difference between depletion mode and enhancement mode. To form a thin layer of silicon-oxide along one side of the channel is easy, and then leave the metal gate region down over the insulator. The gate channel will act as a semiconductor resistance as there Is not current applied to it, P-N junction is not formed nor the depletion layer because the whole conduction of current depends upon the voltage applied between source and drain. If we apply sufficient voltage across source and drain the current will flow through the channel. When negative voltage is applied through the gate terminal it will repel electron charge away from the gate terminal. But as N-type contain majority electron charge carriers by repelling then away from gate the applied negative voltage will create a depletion region. So the process is called Depletion Mode Metal-Oxide Semiconductor Field Effect Transistor. THE ENHANCEMENT MODE MOSFET: Enhancement mode contains two N-type channel and one P-type channel which is sandwiched between both N-type as shown in fig 2. Applying the positive voltage to the drain terminal with respect to source terminal and applying positive terminal to gate terminal. As a result it will attract all the free electrons towards the gate. As the positive voltage is increased the electric field will also become wider and more electrons are attracted. There are free electrons in P-type, source junction is forward biased, so the positive gate voltage can attract electrons towards the gate. The electrons which are attracted towards the gate will enhance the channel within the P-type region as shown in fig 3. This will bridge the gap between source and the drain and it will start FIG 2 FIG 3 COMAPRISON BETWEEN MOSFET AND BJT: Metal Oxide Semiconductor Transistor (MOSFET) It is semiconductor device having three active electrodes known as Gate, Source and Drain. Conduction takes place due to either holes or electrons. Hence it is a unipolar Transistor. It is voltage controlled device. Its operation depends upon the flow of majority carriers only. It has high input impedance. It is less noisy than tube or bipolar transistor. There are two type of FETs N-channel P-channel. It is simpler to fabricate and occupies less space. It has thermal stability. It can be used as voltage variable resistor. It has very fast switching time. Bipolar Junction Transistor (BJT) It is a semiconductor device consisting of three electrodes known as Base, Emitter and Collector. Conduction takes place due to holes and electrons. Hence it is a bipolar device. BJT is a current controlled device. It operation depend upon the flow of both majority and minority carriers. BJT has low input impedance. BJT device is noisy. There are two type of BJTs NPN and PNP. BJT is difficult to construct and occupies more space. BJT does not have thermal stability. BJT cannot be used as voltage variable resistor. ADVANTAGE OF MOSFET DEVICE: When compared to MOSFET, its switching time is slow Its switching time is 10 times greater than a bipolar junction It has very much switching current. It is less affected by temperature. DISADVANTAGE OF MOSFET DEVICE: It has very high resistance as compared to bipolar transistor. It can be destroyed by high voltage, especially static electricity. USES OF MOSFETs: MOSFETs can also be used as voltage variable resistor. It is also used as an amplifier. It is also used to prevent power losses. It is used as a switch. It is used as a voltage control device. REFERENCES: Books: Owen Bishop (1995), Understand Electronics, Great Britain, Athenaeum Press Ltd.

The Odyssey Essay Paper Example For Students

The Odyssey Essay Paper The OdysseyThe Odyssey is one of the two great epic poems written by the ancient Greek poet Homer. Due to its antiquity, it is not known when or where it was first written, nevertheless, the approximate date and place is 700 BC Greece. Later publications are widespread as the text is transcribed in modern English with no deviation from the original story. The story is set in the lands and seas in close proximity to Greece changing by books as Odysseus, the protagonist hero, recounts of his many fated adventures and misfortunes in a series of flashbacks. Odysseus, a survivor of the bloody Trojan War that left many Greek heroes dead and a city plundered, yearns to return Ithaca and his wife Penelope, who is solicited by countless suitors, yet due to an accidental grievance done to the God of Sea, Poseidon, Odysseus is plagued by misfortunes and spend nearly ten years traveling the seas searching a path home. The Odyssey is written in the third person omniscient perspective, perhaps the only voice capable of integrating Homers usage of the Gods and the supernatural. This perspective shifts as necessary to give the reader a full understanding of Odysseus journeys. In fact, without incorporating the supernatural forces, there would be no way of understanding why Odysseus is met with such inhospitality from certain Gods or constructing a majestic recount of the actions in the plot. Odysseus is the classic Greek hero by all standards. He is a hardened warrior who has fought against the Trojans, a dutiful husband who would journey years to return home, a cunning wayfarer who fares well with any host hostile or amicable, and a mortal in bipolar relation with the Gods. He may be the protagonist, yet as a mortal, he is only a servant to the Greek Gods. Poseidon has a bitter grudge against Odysseus for blinding the Cyclopes Polyphemus, yet Homer balances Odysseus fate by giving him the aid of the Goddess Athena. Thus, Odysseus fortunes and misfortunes are all the deeds and misdeeds of the Gods, and the protagonist is subject to his fate as determined by the supernatural. Homers implications about the life and fate of a man could be easily recapitulated as uncontrollable. Though the Greek Gods do not exist, mans fortunes and misfortunes still contain unexplainable entropy, leaving mortals with no precise knowledge or grasp of their future yet mortals do have an unfail ing sense of hope, just as Odysseus is determined to return home despite his foes and hardships. Odysseus wife Penelope is also an important character in the story despite the fact that Homer only writes in fragments about her. Without any news of Odysseus after the end of the Trojan War, she is treated as a widow and wooed by many soliciting men from the neighboring area. Homer has characterized her with an unfailing constitution and loyalty to Odysseus. She fends off the suitors with her cleverness, exemplified by her pretentious indecisive publicized to all the suitors, and waits desperately for Odysseus for indefinite years. Penelope is seen as stubborn in the eyes of her lovers, yet, unbeknownst to these men, her loyalty will be awarded when the Gods finally return Odysseus back to her as according to his fate. The Goddess Athena also favors her and help guides her faith despite the pressure of the suitors and Odysseuss years away. Homer has fictionalized Penelope with the necessary traits that make an ideal wife in Greek times. She is imbued with unyielding character, quic k wit, and lasting beauty. Athena is a prominent figure of the plot. According to Greek mythology, she is the daughter of Zeus, King of gods and men, and the goddess of wisdom and battle. As with many feminine supernatural figures in The Odyssey, she has a predilection for Odysseus and would watch over him passively throughout the plot. Homer has underscored her aid to Odysseus to counterbalance the weakening brought upon him by Poseidon. This careful equilibrium of heavenly forces is the constant recurring element in the plot that keeps Odysseus alive yet suffering at the same time. Her appearances in the plot are often under the disguise of mortal figures, mystifying her true identity as a goddess to all, yet she does reveal herself to Odysseus at several points, which shows a deep favorability that Homer protrudes to glorify Odysseus. Emily Dickinson, A Creative Poet During The Mid-nineteenth Century, Wr EssayHomer also uses the monsters in The Odyssey as indirect depictions of his ideas. The Cyclops Polyphemus, a behemoth giant, symbolizes natures brute force. It has the power of hundreds of men, yet it is hindered by a diminutive intelligence. Thus, Odysseus cunning defeat of Polyphemus proves to be the conquest of wit over strength. Homer also glorifies the evolutionary advantages of mortals mind over pure nature, yet Homer carefully limits this daring statement by introducing Poseidons vengeful punishments. Perhaps Homer has two contrasting messages about mans abilities over nature: man can defeat nature because of his intellect, yet it is often unwise to clash against nature. Another monster, the Sirens, is the apparent embodiment of all the deceitful temptations in mans life. The Sirens persuade men into their traps by beautiful hypnotic songs. Once a sailor has entered their trance, his or her life is doomed to Hades. Homer shows that there are many false enticements in the world; the only way to pass these obstacles is to maintain a linear course and never deviate from a fortified moral constitution. To be persuaded by these temptations is to fall into the fatal control of others, to be used without knowing. In the story, Odysseus hears songs about Ithaca and he is filled with nostalgia at that moment, yet his men controlled the ship and steered clear of danger. Sometimes, these temptations may be so alluring that a momentary emotional outbreak occurs, yet man should never rely purely on emotions, rather, rational thinking and logic must be prioritized to prevent fatal mistakes. One other monster, the six-headed Scylla, is the symbol of sacrifice. As Odysseus sails past the strait between Scylla and the whirlpool of Charybdis, he is forced to make a harsh decision to sail by Scylla and lose at most six sailors rather than sailing by Charybdis and lose the entire crew. It was a hard decision for Odysseus to make, yet it is the only way to save the entire crew. Homer establishes a clear message about the necessity to sacrifice in time of need despite certain unpreventable losses. Another important symbol employed by Homer also concerns the deities. Every time a deity visits Odysseus, a mortal form is chosen and the deitys true identity is kept secret. This disguise represents the idea that life can never by judged purely by the outlook. The true significance of things is not proportionally reflected by their material form. The suitors can also be seen as thugs in disguises of gentlemen. Even though they promise to be civil visitors in the residence of Penelope, they are truly symbols of the lowest form that men can be. Their characterizations bring up only disgust and hatred, the far extreme low point of humanity. In other terms, the manifestation of anything may either be an overstatement or an understatement of the truth. Relevant to this idea, Homer also mentions the importance of modesty and amicability. Odysseus is always humble and gracious to the people he meets, despite their stature in the world. This is one of the many characteristics of Odysseus th at makes him welcomed by many. Homers theme may be that hospitality is one of the more honorable traits of humanity and a moral that should be shared by many. Homer has built a myriad of symbols and themes in The Odyssey. His epic is not only an entertaining enduring literature, but an education and enlightening of the mind. The plot moves continuously from action to action, yet weaved within the twenty-four books of this poem is numerous life lessons that are invaluable to even the modern society.

What Is the Purpose of the Why BU Essay? Many schools require a â€Å"Why this school† essay. Why? Because colleges want to see that you really want to attend their school. Students who love their school are more likely to be active and happy students and later, active and happy alumni. Your essay should show the admissions committee that you really love Boston University, which will make them feel more confident that you’ll be a great addition to the campus. If your essay is generic or nonspecific to Boston University, the admissions committee will worry that you’re not invested in attending. They may even think that you don’t care about getting into Boston University, which could cause them to pass over your application in favor of another student’s who really wants to attend. Basically, Boston University wants to make sure you know and value what they offer, and they also want to assess how you’ll take advantage of the many opportunities on BU’s campus to further your academic and professional career. What Should I Write About in My Why BU Essay? So what should you write about in your Why BU essay? You should identify concrete reasons why BU is your dream school. Here are three ideas for topics. #1: A Specific Course or Professor You'd Like to Study With One of the ways to demonstrate your excitement for attending BU is by highlighting a specific course you’d like to take or professor you’d like to study with. Universities don’t share their course schedule or their professors, so the offerings at BU are unique to BU. If you highlight a specific class, it shows why you’re interested in taking advantage of BU’s academics. You should have a concrete reason for wanting to take this class or study with this professor. Tie your interest to your long-term professional goals so that the admissions committee sees how attending BU will help you invest in your future. If you go the professor route, make sure you highlight why this professor is so special to you. Is he or she a leader in his field? Have they done interesting research lately? Are they known for teaching in a unique way? Whatever the reason, make sure it’s strong - you don’t want to feel like you’re inventing something. #2: An Interaction You Had With a Current or Former Student Talking about BU with a current or former student shows your passion for the university and highlights that you’ve taken the initiative to learn more. Students are able to speak to the vibe on campus, as well as why Boston University is a great place to spend four years. Name-dropping a current or former student will show that you really believe Boston University is the right school for you. When you’re recounting your conversation, remember that your reasons don’t have to be particularly highbrow or impressive. You can talk about how you were excited to learn about the intramural kickball teams, for instance. Just pick specific reasons that your conversation resonated with you. #3: A Program You’re Excited About Participating In Boston University has a number of unique programs, including their Honors College, Film/Television department, and Engineering programs. If you want to participate in a specific program, you can talk about that in this essay.

Whatever the program, make sure you highlight a few specific features and explain why they’re important. Tips for Writing an Amazing Why Boston University Essay You want your Why Boston University essay to be as strong as possible.

Your admissions essays are your opportunity to make yourself come alive for the essay readers and to present yourself as a fully fleshed out person. You should, then, make sure that the person you’re presenting in your college essays is yourself. Don’t try to emulate what you think the committee wants to hear or try to act like someone you’re not. If you lie or exaggerate, your essay will come across as insincere, which will diminish its effectiveness. Stick to telling real stories about the person you really are, not who you thinkBU wants you to be. #2: Be BU-Specific Nothing about your Why BU essay should be generic or impersonal. The more specific you can be when answering this prompt, the better. Don’t say Boston University has great academics, caring professors, and an interesting student body. The admissions offers don’t need you to tell them that. Similarly, don't talk about why you want to go to school in Boston. There are hundreds of colleges in Boston - you need to highlight why this specific school is the right one for you. Everything you write about in your Why Boston University essay should be specific to Boston University - from the names of the professors and the courses to the feeling you had while visiting the campus.

Supporting Activity - Essay Example The process is complemented by the cost factor, taking into account the budgeted funds and resources directed to the acquisition of systems. Cost becomes a major issue due to the fact that systems vary in quality, capacity, and pricing, and the acquiring firm only does so within its financial potential (Parno, McCune & Perrig, 2011). On the same note, the role to be played by these systems must be accounted for in ensuring that appropriate and effective systems are acquired. Once the required systems have been acquired, maintenance must be undertaken from time to time for the purpose of ensuring that the acquired systems serve their purpose both in the short run and long run. In maintenance, the commonly faced issues are repair and management, and system upgrading from time to time. Systems require repairs from time to time, making it necessary to effectively manage these systems. Expertise in both repair and management is critical in ensuring that these systems are properly maintained. On the same note, system upgrade cannot be avoided. System developers keep emerging with new and improved versions of the systems that have already been developed (Clements, et al. 2010). In this regard, upgrading systems is a common issue faced when maintaining

Globalisation have dramatically accelerated the pace of change in modern organisations

Globalisation have dramatically accelerated the pace of change in modern organisations Introduction: Technology explosion and globalisation have dramatically accelerated the pace of change in modern organisations (Prastacos 2002). Organisational Change has become a compulsion in order to maintain competitive edge or be successful in modern businesses and a difficult process to implement in practice due to its complex nature (Hamel et al, 1996) The objectives of this report are to look at the significance of change within an organisation, relation between bureaucracy and hierarchy, stakeholders, models for involving stakeholders, models for change and etc within Tesco. Tesco was founded in 1924 by Sir Jack Cohen and had earlier roots from selling groceries in Londons East End markets. The first store to be opened was in 1929 in Burnt Oak, Edgware. The first Tesco self-service store was opened in St Albans in 1948. In the 1960s, Tesco started to sell fresh food, clothing and household goods in addition to groceries and opened stores in high streets of towns across England. In the 1990s, Tesco started to expand its operations outside the UK into Eastern Europe. In 1992 Tesco opened its city center stores under the branding of Tesco Metro. In 1995 Tesco introduced the loyalty card and by the end of the 90s diversified further into banking. In the year 2000, Tesco is Britains leading food retailer with 845 stores. It prides itself on quality, customer service and a customer-friendly environment. Task-1: Question-1: Significant change within an organization: A description of the use of ICT for Internal External Communications of the business; Information and communication technology has totally transformed, over the last few years, which has led to a major change in the way communication flows through a business. This has had a massive affect on the way Tesco operates today, as they are a service-related organisation, as they dont produce their own goods. Some examples of changes in technology that have had an effect on the way Tesco communicates internally and externally are; Email- Is used to replace old methods such as faxes, telephone calls and letters, as e-mail is a lot quicker, especially if the message has to be sent to more than one person, it is more convenient than conventional methods, it is also used to correspond with suppliers. Internet- This allows Tesco to create a communication link with the global market; this allows better communication between staff and customers that are overseas. Tescos website allows its customers to see what they are doing externally (e.g.) how they help the local community, it also allows them to explore Tescos range of products and services. Customer can browse through 24 hours a day from anywhere in the world. Network Databases- Has allowed Tesco to replace the old traditional ways of filling and storing information. Customer Service-At Tesco any questions or complaints can be dealt with over the phone or through the Internet, this makes the communication process a lot quicker. Payment Methods- There are a number of ways in which Tescos customers can pay for their goods or services, some of the payment methods that are accepted at Tesco are; Cheque- Details can be printed out at the till, using the information given to produce a receipt. Cheques can be used to pay up to a given price. Debit Card- This allows the customer to pay for their goods or service without any cash, the transaction is automatically checked at the customers bank account, the payment is guaranteed once it has been checked if there is enough in the persons account. Credit Card- This is a similar process however, the money is not taken from the customers account, the sale is paid for at the time. Customers may also ask for up to £50 cash back. IT in store Operation- Information Technology is essential for any large organisation affectively, it is used for many in store operations, for example, monitoring sales, ordering stock etc. Tesco sell thousands of products, therefore they use computerised merchandising systems, to order the correct products to the correct place without these type of system it would be a very long process. Goods are no longer entered manually, which means accurate pricing is guaranteed, because Tesco sell thousands of products, each item has an individual barcode usually printed somewhere on the package, this allows Tesco to monitor their stock levels, which means that once a certain amount of a particular product is sold the computer will automatically re-order the product, this is known as the Sales Based Order. Home Shopping- Tesco has introduced a home shopping service with the use of information technology, this enables people to order their shopping from home using the internet, this is done through a computer programme, it allows its customers to order any of the products that the particular branch sells, orders can be placed 24 hours a day, orders are delivered to the customers home. These home shopper customers have to register and are given a personal ID number, payments for shopping can be made by debit and credit cards. Responsible some factors for significant change: The major sources of changes are the Environmental firstly, taking the shape of economic and political change where we had the rise of enterprise economy and market led economies. Moreover, new work patterns have emerged where more pat-time workers and permanent employees are used nowadays, and with the rise of competition from Europe, Japan or multinational corporations have made it difficult to cope correctly with employees. Finally, we must note the various and fast technological advancements which take place and the shortening of product life cycles that lead to short range strategies and increased flexibility. These factors are discussed as below: Competition in Marketplace: Since year 2004, Tesco, who considers to be a market leader as a Grocery retail sector in the UK not only faced first ever fall in its profit on sales but also faced fierce competition from existing new chains of food retailing market. It is true that falling sales and the first loss in the companys history have forced them to think about radical changes. The UK food retailing market is mature and highly competitive. In addition, the UK market has been affected by negative inflation in the food sector. This negative inflation has been driven by the so-called Wal-Mart effect i.e. downward pressure on prices from Asda / Wal-Marts aggressive Every Day Low Price strategy; it was the Wal-Mart effect that pressurized TESCO into a price war. Changes in Attitude of Customers: Due to high competition, company has faced a considerable change in attitude of customer towards its products. As a maneuver, Tesco has been making continuous attraction strategies for its customers to keep them in close intact in order to remain at top position. So, they always try to bring most attractive goods for the customers. The new option in the goods has been very well advertised nationwide as a result customers are very well attracted towards Tesco. Political factor:  ¨Ã‚  Ã‚   Public concern about the effect of out of town superstores on town centers has grown and both current and future planning policies will seriously hamper future development. Though conversions of existing stores allow some increase in selling space it is limited.  ¨Ã‚  Ã‚   Community organizations have since gained momentum consequent to the Competition Commissions ruling and have been lobbying neighborhoods to boycott supermarkets and large food manufacturers and instead support small independent suppliers, processors and retailers at the expense of large supermarkets like TESCO. Economic:   Businesses cannot control their environment however much they would wish to, instead they must react / adapt to changes within the environment, and this is particularly true in relation to the economy. In periods of recession, many businesses are forced to reduce staffing levels, whilst in boom periods of high growth businesses may seek to expand the size of their workforce to cater for increasing levels of demand for their goods / services. Whilst the UK economy has seen steady overall growth, there has for some time been a cycle of boom and slump within the economy, which has forced businesses to redefine their staffing needs. Social:  ¨Ã‚  Ã‚  Ã‚  The U.K population on a whole is far more health conscious than in previous years. There has been a trend away from genetically modified foods towards organic foods.  ¨Ã‚  Peoples wealth increases, with the decrease in time for shopping. Besides, people enjoy a busier lifestyle, fewer people cook everyday for themselves. Therefore, the ready meals have become welcome by consumers. Technology: The increasing dependency of businesses on technology to gain competitive advantage over competitors, and the subsequent need to keep pace with technological advances have resulted in increasing emphasis being placed on organisations ensuring that their staffs skill base is constantly re-assessed and developed, through training and recruitment to keep pace with the use of technology.  ¨Ã‚  Ã‚  Ã‚  The Grocery retail sector is a major user of new technology. The increasing use of electronic data interchange, laser and self-scanning and other point-of-sale equipment has been a feature of recent innovations by retailers. The use of loyalty cards and the provision of financial and other services have also involved the introduction of sophisticated computer-based systems. Globalization: In the presence of globalization factor, Tesco also change its policies accordingly. This is considered to be one of the major changes in Tesco operations. Same trend has been showing in international regions also. By that company is working on a change to build strong reliable partners. Conclusion: Organisations are a vital part of our society and serve several important needs and demands.   How an organisation is managed in relation to actions of management and the decisions made have an impact on all concerned including other organisations, the community environment as well as individuals. As consumers plays the lifeblood role in Grocery Retail industry, TESCO approach remains Re-active, were it adopts low price strategy to attract customers. Also TESCO is often forced to change their strategy as the competition changes. Question-2: Relation between bureaucracy and hierarchy to the organisational structure and change: A bureaucracy is a type of organisational structure that is found in many large-scale organisations. It appears in both public and private organisations and is a structure that still exists in the majority of industrial organisations in the world, despite being around since the 18th century. Ideally bureaucracy is characterised by hierarchical authority relations, defined spheres of competence subject to impersonal rules, recruitment by competence, and fixed salaries. The main aims of a bureaucracy are to be rational, efficient, and professional. German sociologist, Max Weber was the most important student of bureaucracy, and he described bureaucracy as technically superior to all other forms of organization. Bureaucratic systems have a greater sense of direction and purpose than other types of organisation structure and this helped by the hierarchy of positions and well developed rule system that is consistent in a bureaucracy. Hierarchy structure is sometimes called the Pyramid structure. In this structure there are few people who working above others. These people such as Marketing Manager have more authority over their employees. In many businesses each part of the department is divided into specialists departments where they deal with different task but have the same overall aim. Management in this structure is led by Vertical Communication, which means that the communication goes from the top of the structure to the bottom of the structure. Advantages and disadvantages of bureaucracy and hierarchy organisational form: Weber stressed (Conley, 2002) both the advantages and disadvantages of bureaucracies. Advantages of bureaucratic system: Bureaucratic system is a very effective way of structuring an organisation. So, it has some advantages like as below: Bureaucracies provide a hierarchical structure whereby workers can rise through the ranks to positions of relative power. Progression is based on technical expertise thereby increasing the professional management of organisations. The development of written rules offered protection to less powerful workers and provided a basis for trade union negotiation. Bureaucracies replaced nepotism and favouritism with impersonal social relations and the basis for equality of treatment. Disadvantages of bureaucratic system: Although, bureaucracy organisational form is very effective for an organisation but it also offer various drawbacks which are as below: Hierarchies and rules formalise power structures and status divides in workplaces Rules cannot cover every eventuality and are themselves subject to interpretation. Over-attention to a rigid set of rules can often hinder the smooth running of an organisation Bureaucracies can create iron cages which dehumanise work The advantages of hierarchy structure are: A leader or leadership team can give the business a direction A leader or team could make quick appropriate decisions on behalf of the organisation. Employees are clear about their position and Span of control within the organisation. Employees know who to report to in events of problems instead of going to the owner directly for irrelevant issues. Employees become motivated because they get a chance to become promoted to a higher tier. The disadvantages of hierarchy structure are: Decisions can often take time to follow the chain of command. Employees can be demotivated if there are considered as at the bottom of the hierarchy. Decisions may be made by a few that are not in the interest of everyone on the organisation. After researching I have found out that the main structure that Tesco operate in is Hierarchy I think that this is a good structure mainly this is because there are more advantages then drawbacks plus this is a good structure to operate in for a big company like Tesco. Question-3 Compare and contrast of bureaucracy and hierarchy organisational form: Bureaucracy can have a positive effect on the organisation it could also cause alienation and sense of purposelessness from workers within the system. Working in a large bureaucratic organisation may induce the feeling that they are mere cogs in a huge machine, and therefore lead to unmotivated staff and a decrease of efficiency. Communication through the hierarchy may well be slow in a bureaucratic system, due to the tendency towards centralisation, which would affect the initiative at the lower levels. Due to the bureaucratic systems being well suited to predictable and stable situations, they are not very flexible and therefore find it hard to deal with conditions of change. The rules of a bureaucracy are very rigid and are designed to achieve organisational objectives. However due to the rigidity it may obstruct the attainment of goals and lose sight of its overall organisational objectives. Although bureaucracy has proved its need in the current business environment, there are still several downsides, not only for the organisation, but also for the employee. Many argue that in the twenty-first century, a bureaucratic organisation will be too expensive to maintain. It will also be incapable of responding quickly to change and will not be using the innovative resource of its members. Due to the hierarchical system, problems are usually passed upwards, preventing employees contributing to decisions, which will not promote proactive behaviour and can be damaging to an organisation. Task-2 Question-1 Stakeholders: A stakeholder in an organization is any group or individual who can affect or is affected by the achievement of the organizations objectives. (R. Edward Freeman, 46). In the changing business world, a wide range of stakeholders may have an involvement with an organization, such as shareholders, customers, investors, employees, the media, government and non-government organizations. Internal and connected stakeholders: Internal stakeholders include normal employees and managers of a business. In Tesco, the shareholders, the customers and other groups or individuals are involved in the business. These people are called connected stakeholders. All these are very important to Tesco. 1.  Employees: All the employees are important stakeholder to Tesco. The reason for this, that employees are closely involved with organisation. They have a strong influence on the business and the way that the business runs. The expectations that the employees have on Tesco are: A clean and safe working environment Job security Competitive pay rates and benefits such as discounts on Tesco products Interesting and rewarding work Opportunities for promotion and career structure Bonuses 2. Managers: All mangers as well as the directors of the company are stakeholders. In Tesco the manager has a major say on how the business should be run. The expectations that the manager has on Tesco are: developing a local or national reputation as a successful manger working the business to make it bigger than it is now For example at Tescos, those with a high achievement need such as Duty managers or departmental managers tend to seek situations where they have personal responsibility for solving problems, managing projects or for overall performance. 3. Shareholders: This group of stakeholders are interested in the financial part of the Tesco. The expectations that the shareholders has on Tesco are: Shareholders of Tesco want to receive a large and increasing proportion if the companys profits They also hope the companys share price will rise 4. Customers: Tesco are mainly focused on customers. This means that Tesco has to fill the expectations of their customers. These include: Good quality products delivered on time Fair prices After sales service and support, especially for high- technology products. This shows how Tesco are influenced by their customers- Tesco, the UKs largest retailer, buys enormous amounts of products from suppliers and so has great influence. 5. Suppliers: They are expecting to be paid on time and receive regular orders from their customers. Tescos suppliers are interested in any development that might affect the number and size of the orders. Tesco buys its own brand products from suppliers. All products are supplied to Tesco in a finished state. 6. Bankers: Banks and other financial organisations lend money to Tesco and will be concerned that their money is saved. They want Tesco to run successfully and to earn profits. External stakeholders: External stakeholders include individuals or organisations that have interest in the business but do not do anything and have no relationship with that business. 1. Government agencies: The government has lots of reasons to be interested in Tesco: The Inland Revenue collects income tax and corporation tax for Tesco. It is interested in the financial affairs of Tesco Customs and Excise collects Tescos taxes. It collects value added tax (VAT) 2. Pressure groups: These organisations are groups of people who combine to promote a particular view or cause. Pressure groups attempt to influence Tesco by: Campaigning Taking direct action against some firms. Tesco responds to pressure group because they want to have a good public image. 3. Local communities and society: Businesses are an important part of the society. Local communities expect Tesco to: provide stable employment for the community Avoid causing environmentally pollution, noise or other problems that might offend the community. Question-2 Models to involve stakeholders: In recent years, two useful models -a) the Power/Interest Matrix (Mendelow cited in Johnson and Scholes, 2002:208) and b) Power/Urgency/Legitimacy Model (Mitchell, et al., 1997) have become popular. Brief Introduction of these Two Models: To assist the analysis, the introduction of the two models is briefly explained in this section. a) The Power/Interest Matrix (shown as Figure 1) implies the political priorities for managing stakeholder relationships by assessing the level of interest and power for each stakeholder (Johnson and Scholes, 2002: 208). High Low High Low PowerE:managing environmentStakeholder Management Publications Management Portal.filesimage004.gif C D A B Level of Interest A Figure 1 Stakeholder Mapping: the Power/Interest Matrix Source: Johnson and Scholes, 2002 Adapted from A. Mendelow, Preceedings of the Second International Conference on Information Systems, Cambridge, MA, 1991. Source: It can be seen from Figure 1; the stakeholders in Segment D have the most important role among other stakeholders in the success of the strategy. Due to their high power, organisations should give adequate emphasis on the stakeholders in Segment C and attempt to meet their expectations. As for stakeholders in Segment B, organisations need to provide enough information to satisfy their high interest in the strategies or issues. Under some circumstances, some stakeholders (Segment A) neither have power nor interest, so it is unnecessary to invest too much in this group. b) The Power/Urgency/Legitimacy Model, illustrated as Figure 2, divides stakeholders into seven types and uses them to reflect a different degree of stakeholders salience which is related to the three basic attributes power, legitimacy and urgency perceived by organisational managers (Mitchell, et al., 1997). Legitimacy Power Dormant Discretionary Definitive Dominant Dependent Dangerous Demanding Urgency Figure 2 Power/Urgency/Legitimacy Model Source: Based on Mitchell, Agle and Wood 1997 Mitchell, et al (1997) made detailed explanations for the three attributes. Power means the possibility for a stakeholder to influence the outcome, originating from coercive, legitimate, expert, referent and reward. Urgency indicates time sensitivity and criticality of the situation. Regarding Legitimacy, it refers to the desire of stakeholders to judge the properness of the issue, based on norms, values and beliefs. Both two models are helpful to managers in pursuing success in stakeholder management. However, it is important to realise the limitations that each model might have in order for effective utilization of them. Question-3 Stakeholder mapping in Power/interest matrix model: Stakeholder mapping identifies stakeholder expectations and power and helps in establishing political priorities (Johnson, G Scholes, K. 1999: 215). This mapping can be carried out by means of Power/Interest Matrix (Johnson, G Scholes, K. 1999: 215), which classifies stakeholders in relation to the power they hold and the degree of interest they show to the organisation (Refer to Figure 4). Low A Minimal Effort B Keep Informed High C Keep Satisfied D Key Players Power Level of Interest Low High Figure 4-Stakeholder mapping: Power/Interest Matrix (Johnson, G Scholes, K.) Apply Power/Interest Matrix to Tescos Stakeholders: Considering the comments of Power/Interest Matrix for each group, we can ignore Segment A because it only has minimal effort on Tesco. As to Segment C and D, they are all key stakeholders and their expectations should be satisfied continuously. While for Segment B, it has high interest in Tesco and should be properly addressed through informing information to it. Indeed, stakeholders of Segment D (Owners, Top Managers, and etc) have the expectations of good payback and dividends which require Tesco maintains its profit generation in its strength business Traditional Imaging. On the other hand, these stakeholders also seek for capital growth in somewhat more potential business such as Digital Imaging. Stakeholders of Segment C (Customers) always expect better value for money, and they also enjoy the alternatives and value-added products Tesco provided, which ask Tesco to integrate Traditional Imaging with Digital Imaging to generate more innovation. Conclusion: Generally, the expectations of stakeholders of Tesco are diversely and variously. It is clearly that we should find out the key stakeholders and balance their expectations. Here, Owners, Top Managers, Creditors and Customers are identified as key stakeholders of Tesco and in particular their expectations are assessed separately. Obviously, Power/Interest Matrix points out the type of relationship which the organisation need to establish with every stakeholders group. Thus it is helpful in assessing the political ease or difficulty of particular strategic as well as in planning the political dimension of strategic changes Task-3 Question-1: Models for change: There are various models of change are established over the period of time. Every organization can develop adapt any of those models in change process according to the individual circumstances. Two important models of change which can be used during change management are as follows: Business Process Re-engineering (BPR) Total Quality Management (TQM) I have shortlisted two organizations for the said topic in order to expedite a brief report about adaptation of different models of change as and when required by them. The first organization was Tesco, London, UK. I worked as Manager Administration with this company for two years. When I joined the organization, it was in a recession phase due to certain circumstances. In those situations, management of the company including me decided to develop adapt the Business Process Re-engineering (BPR) model of change.   1. Business Process Re-engineering (BPR):-    BPR has four basic key components: Business Processes, Management Measurements, Jobs Structures, and Values Beliefs. BPR is considered to be a much more top-down managed form of change. BPR is best defined as: The fundamental rethinking radical redesign of business processes to achieve dramatic improvements in critical, contemporary measures of performance.   For clarity, it is appropriate also to define what BPR is not. BPR is not automation, restructuring or reorganisation, or delivering although these may be consequences of a BPR exercise. It is also helpful to consider why Tesco contemplated BPR given its radical nature. There were three probable reasons: The business was failing there was no option but to invoke radical change. Business difficulties were foreseen pre-emptive measures were deemed necessary to avoid business failure. The organization, rather than resting on its laurels wished to build on its success invoked radical change to widen its lead over the competition. 2. Total Quality (TQ):- This model of change was developed adapted by the organization operating by the name of Integrated Business Services (IBS), London, UK. In said company I was worked as Manager Sales Marketing. The company is the top rated production manufacturer house of various technical products including aerospace materials. TQ change model was used by the company in January 2004. The Brief description of the model is as follows: TQ comprises change invoked through four key components: Systems, Processes, People Management. TQ is best defined as meeting customer requirements in a context in which every individual in the organization is a customer of the process preceding their own, a supplier to the process succeeding their own. Thus customers are internal to the organization as well as external. Additionally TQ is a competitive concept because it is concerned with being the best, where best is defined by the market place rather than by the product or service provider the best companies will achieve the level of superiority that is usually high. Customer focus is the essence of TQ. Question-2: Necessary steps for planning the implementation process of the Business Process Re-engineering (BPR) model:- The Four Cornices of BPR Considered by Tesco plc-   1.  Business Processes: The essence of BPR for Tesco plc lied in the adaption of a process orientation. The characteristics of such an orientation were: Multidimensional:  Cross-functional working in organization required combining many tasks into one job or process, in so doing, eliminated hand-offs, reduced administrative overheads associated with controlling the previous fragmented steps provided a single point of contact for process-related queries. Continuous Improvement: BPR recognized continuous improvement in the form of process maintenance continual re-examination redesign of processes which, with time, once more became fragmented. 2.   Management Measurements:- The achievement of a process orientation demanded: Process Mapping:  Existing processes were process-mapped to establish what currently happens why, that was, to develop an understanding of current process. Benchmarking: World-wide cross-industry process comparisons were then be used to establish best practice provided a possible basis for process re-design. 3. Jobs and Structures:- The results of BPR in this regard were typically the following: Flat Structure:  Flat structure was adapted, a process rather than functional orientation, which together with process-teams performed managerial functions, reduced bureaucracy the requirement for complex, multi layer managerial hierarchies. Job Specification:  Job descriptions became comprehensive included details of required level of key competencies such that increased objectivity accuracy could be applied to selection appointment processes. 4. Values Beliefs:- Creating sustaining a process orientation in the Tesco plc demanded: Living the Values:  Senior management lead by example in Tesco plc in this regard. For example: by demonstrating the notion of being customer-facing by spen

Creon Antigone by Sophocles Essay

In Antigone, written by Sophocles, Creon dominates the play with his powerful yet arrogant personality. Even though Antigone is the name of this play, Creon, the ruling king of Thebes with a no turning back attitude, proves to be the main character. Creon rules over everyone but that does not stop the intelligent Antigone from protecting her brothers dead body. She gets caught in this illegal act by the very dynamic character of Creon. There are endless personality traits to describe Creon, but certain traits that pop out are his strength/power and his stubbornness. Who is the man here, she or I if this crime goes unpunished?(Scene 2, lines 82,83). This quote is a simple example of how stubborn a king with that much pride can act toward his own family. We then learn that no matter how wrong he is in his decisions, he still sticks with what he believes to be the right punishment to Antigone. The other proving quote in Scene 3 (line 26) is when Creon states, Do you want me to show myself before the people? Or to break my sworn word? No, and I will not. Creon slowly starts to realize the right thing to do in his situation but something inside of him prevents him from saving Antigone. It could quite possibly be him knowing his own strength and power compared to everyone else. His strength plays a key role in the problems that occurred. Antigone sees right through this personality trait of his. Creon is not strong enough to stand in my way.(Prologue, line 35) Also,in Scene 1 line 118 Creon says,Theres nothing in this world that is more demoralizing than money. Creon really means it when he says this. He thinks that everything in the world has a price. His strength can be translated as a waste cause he doesnt use his powers for the better of the city of Thebes. His power completely forces him to believe that no one is above him. That is where the conflict began for Antigone and Polyneices. There was not much motivation for his actions besides his pride, which is apparently the cause of all their troubles. If Creon would have realized early on that the right thing to do is more important then power and pride, Antigone would not have of been dead. In Scene 2, (line 75,76) Choragus is right on when he says, Like father, like daughter both headstrong, deaf to  reason. Creon believes that his word over all should be the final say. But when Antigone, a female at that, defies him, he flips out and sentences her to rot in a prison cell. In his mind, he was rational with the choices he made. When it comes down to it, Creon was just trying to represent the position of the king. Unfortunately, his greed overcame his responsibility of the throne. His power against everyone else in Thebes proved to be significant when he sentenced Antigone. After the events that happened, he was still so stubborn to turn back. At the very end of this play, Creon finally realized his wrong doings and he said, I was the fool, not you. And you died for me.(Scene 5, line 92) Both his stubbornness and his power broke down and we saw the real Creon. Characters like this in Greek literature are important because the form the plot, the conflict, and the resolution. Without the Creons in plays, there would not be any tragedy or any thing to resolve at the end.

Computer Fraud Essay - 1185 Words

Computer Fraud As much as $40 billion are lost every year due to flourishing computer crimes. In 1993 alone, Internet, the world wide system of computer networks, was swindled out of approximately $2 billion, and about $50 million were stolen from various companies such as GTE Corp., ATT, Bell Atlantic and MCI ( Meyer and Underwood 45). Ironically these same organizations have been collaborating with software manufacturers for an expanded software production ( Cook 53 ). Multinational corporations and international authorities are threatened by these innumerable white collar crimes since such crimes are most difficult to prevent, and/or detect and highly profitable to the offenders ( Stern and Stern 525 ). This ever growing menace to†¦show more content†¦In 1994 only, companies estimated to have lost $8 billion due to piracy ( Hall and Vancura 108 ). Figure 1 How to prosecute offenders? Furthermore, Internet Frauds are very difficult to prevent because a long time is required for most of t hem to be discovered. For instance, law enforcers need not only at least equal scientific and technical ability as the offenders, but also precious time and energy to examine company books and accounts to unravel such crimes ( Croal 14 ). It is also felt that prosecution is often incorrect and counter productive (Southerland 85). When the crimes are uncovered, the laws are too vague and too limited for proper prosecution ( Stern Stern 528 ). The complexity of Internet fraud makes it very difficult for legislators to estimate the extent to such offenses, thus leaving many loopholes to be exploited by alert offenders. Moreover, Internet offenses and offenders do appear to enjoy structural advantages, and the outcome of the policies pursued by law enforcers is that many avoid public prosecution and punishment ( Croal 91). Furthermore, it is widely believed that so little has been done to prevent such computer crimes although adequate defensive technology is available for such preven tion because computer owners and governments are arrogant and apathetic ( Schwartau 313-314 ). Nevertheless, at some point in the very near future, they will not afford any longer to be so.Show MoreRelatedComputer Fraud And Abuse Act ( Cfaa ) And Cyberbullying Essay1665 Words   |  7 PagesEmily Jessep Intellectual Property Crimes Professors Dreyfuss and First November 15, 2016 INCOMPATIBLE: The Computer Fraud and Abuse Act (CFAA) and Cyberbullying I.
