African American Musuem Essay

The African Museum in Philadelphia is notable as the first museum funded and built by a municipality to help preserve, interpret and exhibit the heritage of African Americans. Opened during the 1976 Bicentennial celebrations, the AAMP is located in historic Philadelphia, a few blocks away from the Liberty Bell. Charles H. Wesley was a noted African American historian, educator, and author. He was the fourth African American to receive a Ph. D. from Harvard University. An ordained minister, Wesley’s distinguished career included 40 years of leadership with the African Methodist Episcopal Church. In 1976, he served as Director of the Afro-American Historical and Cultural Museum in Philadelphia, now known as the African American Museum in Philadelphia. Programs The African American Museum that is located in Philadelphia, Pennsylvania has some interesting education programs. These education programs focus on arts, culture, and heritage education. They place a major emphasis on the interests of the students, educators, artists, historians, scholars, and community organizations. These programs offer diversity with scheduling. The programs explore various African forms of cultural expressions. In these programs there are literary performances, hands on demonstrations, workshops, and storytelling performances as well. The African American Museum in Philadelphia feels its programs can be a vital link between the permanent and visiting collections for the many communities they serve. Exhibitions The exhibitions in the African American Museum in Philadelphia can some to be pleasing to the eye and stimulating to the mind. According to the African American Museum of Philadelphia these exhibitions invoke a deep collection of emotion ranging from pride and passion to excitement and enthusiasm. When visitors enter the museum they will come to Gallery 1, which includes a interactive timeline, images draw from historical record, that spans 100 years of history. In Gallery 2 there are full size video projections in which visitors can in engage in them. Once they are activated, a monologue about life in Philadelphia will begin.

In the 2004-05  fiscal year, it is the  Steel Authority of India Limited's most profitable plant. This steel plant was set up with the help of the USSR. Nine – time winner of Prime Minister's Trophy for best Integrated Steel Plant in the country. The plant is the sole supplier of the country's longest rail tracks of 260 metres. With an annual production capacity of 3. 53 MT of saleable steel, the plant also specializes in other products such as wire rods and merchant products. Since BSP is accredited with ISO 9001:2000 Quality Management System Standard, all saleable products of Bhilai Steel Plant come under the ISO umbrella. At Bhilai IS0:14001 have been awarded for Environment Management System in the Plant, Township and Dalli Mines. It is the only steel plant to get certification in all these areas. The Plant is accredited with SA: 8000 certification for social accountability and the OHSAS-18001 certification for Occupational health and safety.These internationally recognised certifications add value to Bhilai's products the best organizations in the steel industry. Among the long list of national awards it has won, Bhilai has bagged the CII-ITC Sustainability award for three consecutive years. Bhilai Steel Plant manages a well planned township (Bhilainagar) which as 13 sectors. It was deliberately located in what was then regarded as a remote and â€Å"backward† rural area, profits being secondary to employment in the planning priorities of the time.BSP currently has nearly 55,000 permanent workers on its direct pay-roll, of whom approximately three-fifths work inside the 17 square kilometer plant and the remainder for its associated mines and quarries, and for the purpose-built BSP township. This compares with a regular workforce of 63,400 in 1987. In addition, on any one day there are at present something in the region of 8,000 contract workers employed by the plant and the township, and a further 3,500 – 4,000 employed by the mines. BSP has for some years shown a profit, and is widely regarded as the most successful of those in the Indian public sector.It runs at its four million ton capacity; produces cheaper steel, and has a record of considerably more harmonious industrial relations than any of the other state-run steel plants, and also than the vast majority of private sector factories which now surround it, and for which it served as a magnet. Though local job creation was one of its main objectives,  and though the principle was soon established that one member from every family which had relinquished land should have an automatic right to BSP employment, the local Chhattisgarhis were initially reluctant recruits.Location : Forty kms west of Raipur, the capital city of Chhattisgarh, along the Howrah-Mumbai railway line and the Gr eat-Eastern highway, stands Bhilai Steel Plant (BSP).

HEAVY MAINTENANCE ELECTRICALS MAINTENANCE OF MOTORSThe key to minimizing motor problems is scheduled routine inspection and service. The frequency of routine service varies widely between applications. Including the motors in the maintenance schedule for the driven machine or general plant equipment is usually sufficient. A motor may require additional or more frequent attention if a breakdown would cause health or safety problems, severe loss of production, damage to expensive equipment or other serious losses. Written records indicating date, items inspected, service performed and motor condition are important to an effective routine maintenance program.From such records, specific problems in each application can be identified and solved routinely to avoid breakdowns and product ion losses. The routine inspection and servicing can generally be done without disconnecting or disassembling the motor. It involves the following factors: Dirt and Corrosion: 1. Wipe, brush, vacuum or blow accumulated dirt from the frame and air passages of the motor. Dirty motors run hot when thick dirt insulates the frame and clogged passages reduce cooling air flow. Heat reduces insulation life and eventually causes motor failure. 2. Feel for air being discharged from the cooling air ports.If the flow is weak or unsteady, internal air passages are probably clogged. Remove the motor from service and clean. 3. Check for signs of corrosion. Serious corrosion may indicate internal deterioration and/or a need for external repainting. Schedule the removal of the motor from service for complete inspection and possible rebuilding. 4. In wet or corrosive environments, open the conduit box and check for deteriorating insulation or corroded terminals. Repair as needed. Lubrication: Lubrica te the bearings only when scheduled or if they are noisy or running hot.Do NOT over-lubricate. Excessive grease and oil creates dirt and can damage bearings. Heat, Noise and Vibration: Feel the motor frame and bearings for excessive heat or vibration. Listen for abnormal noise. All indicate a possible system failure. Promptly identify and eliminate the source of the heat, noise or vibration. Winding Insulation: When records indicate a tendency toward periodic winding failures in the application, check the condition of the insulation with an insulation resistance test. Such testing is especially important for motors operated in et or corrosive atmospheres or in high ambient temperatures. Brushes and Commutators (DC Motors): 1. Observe the brushes while the motor is running. The brushes must ride on the commutator smoothly with little or no sparking and no brush noise (chatter). 2. Stop the motor. Be certain that: * The brushes move freely in the holder and the spring tension on each brush is about equal. * Every brush has a polished surface over the entire working face indicating good seating. * The commutator is clean, smooth and has a polished brown surface where the brushes ride.NOTE: Always put each brush back into its original holder. Interchanging brushes decreases commutation ability. * There is no grooving of the commutator (small grooves around the circumference of the commutator). If there is grooving, remove the motor from service immediately as this is a symptomatic indication of a very serious problem. 3. Replace the brushes if there is any chance they will not last until the next inspection date. 4. If accumulating, clean foreign material from the grooves between the commutator bars and from the brush holders and posts. 5.Brush sparking, chatter, excessive wear or chipping, and a dirty or rough commutator indicate motor problems requiring prompt service. Figure 1. Typical DC Motor Brushes and Commutator Brushes and Collector Rings (Synchronous Mot ors) 1. Black spots on the collector rings must be removed by rubbing lightly with fine sandpaper. If not removed, these spots cause pitting that requires regrinding the rings. Figure 2. Rotary Converter Armature Showing Commutator And Slip Rings. 2. An imprint of the brush, signs of arcing or uneven wear indicate the need to remove the motor from service and repair or replace the rings. . Check the collector ring brushes as described under â€Å"Brushes and Commutators†. They do not, however, wear as rapidly as commutator brushes. BEARING LUBRICATION: Introduction Modern motor designs usually provide a generous supply of lubricant in tight bearing housings. Lubrication on a scheduled basis, in conformance with the manufacturer's recommendations, provides optimum bearing life. Thoroughly clean the lubrication equipment and fittings before lubricating. Dirt introduced into the bearings during lubrication probably causes more bearing failures than the lack of lubrication.Too mu ch grease can over pack bearings and cause them to run hot, shortening their life. Excessive lubricant can find its way inside the motor where it collects dirt and causes insulation deterioration. Many small motors are built with permanently lubricated bearings. They cannot and should not be lubricated. OILING SLEEVE BEARINGS: As a general rule, fractional horsepower motors with a wick lubrication system should be oiled every 2000 hours of operation or at least annually. Dirty, wet or corrosive locations or heavy loading may require oiling at three-month intervals or more often.Roughly 30 drops of oil for a 3-inch diameter frame to 100 drops for a 9-inch diameter frame is sufficient. Use a 150 SUS viscosity turbine oil or SAE 10 automotive oil. Some larger motors are equipped with oil reservoirs and usually a sight gage to check proper level. (Fig. 3) As long as the oil is clean and light in colour, the only requirement is to fill the cavity to the proper level with the oil recommen ded by the manufacturer. Do not overfill the cavity. If the oil is discoloured, dirty or contains water, remove the drain plug. Flush the bearing with fresh oil until it comes out clean.Coat the plug threads with a sealing compound, replace the plug and fill the cavity to the proper level. When motors are disassembled, wash the housing with a solvent. Discard used felt packing. Replace badly worn bearings. Coat the shaft and bearing surfaces with oil and reassemble. Figure 3. Cross Section of the Bearing System of a Large Motor GREASING BALL AND ROLLER BEARINGS: Practically all Reliance ball bearing motors in current production are equipped with the exclusive PLS/Positive Lubrication System. PLS is a patented open-bearing system that provides long, reliable bearing and motor ife regardless of mounting position. Its special internal passages uniformly distribute new grease pumped into the housing during regreasing through the open bearings and forces old grease out through the drain hole. The close running tolerance between shaft and inner bearing cap minimizes entry of contaminants into the housing and grease migration into the motor. The unique V-groove outer slinger seals the opening between the shaft and end bracket while the motor is running or is at rest yet allows relief of grease along the shaft if the drain hole is plugged. Figure 4) The frequency of routine greasing increases with motor size and severity of the application as indicated in Table 1. Actual schedules must be selected by the user for the specific conditions. During scheduled greasing, remove both the inlet and drain plugs. Pump grease into the housing using a standard grease gun and light pressure until clean grease comes out of the drain hole. If the bearings are hot or noisy even after correction of bearing overloads (see â€Å"Troubleshooting†) remove the motor from service. Wash the housing and bearings with a good solvent. Replace bearings that show signs of damage or wear.Rep ack the bearings, assemble the motor and fill the grease cavity. Whenever motors are disassembled for service, check the bearing housing. Wipe out any old grease. If there are any signs of grease contamination or breakdown, clean and repack the bearing system as described in the preceding paragraph. Figure 4. Cross Section of PLS Bearing System (Positive Lubrication System) HEAT, NOISE AND VIBRATION Heat Excessive heat is both a cause of motor failure and a sign of other motor problems. The primary damage caused by excess heat is to increase the aging rate of the insulation. Heat beyond the insulation's rating shortens winding life.After overheating, a motor may run satisfactorily but its useful life will be shorter. For maximum motor life, the cause of overheating should be identified and eliminated. As indicated in the Troubleshooting Sections, overheating results from a variety of different motor problems. They can be grouped as follows: * WRONG MOTOR: It may be too small or have the wrong starting torque characteristics for the load. This may be the result of poor initial selection or changes in the load requirements. * POOR COOLING: Accumulated dirt or poor motor location may prevent the free flow of cooling air around the motor.In other cases, the motor may draw heated air from another source. Internal dirt or damage can prevent proper air flow through all sections of the motor. Dirt on the frame may prevent transfer of internal heat to the cooler ambient air. * OVERLOADED DRIVEN MACHINE: Excess loads or jams in the driven machine force the motor to supply higher torque, draw more current and overheat. Table 1. Motor Operating Conditions Motor Horsepower| Light Duty(1)| Standard Duty(2)| Heavy Duty(3)| Severe Duty(4)| Up to 7-1/2 10 to 40 50 to 150 Over 150| 10 years 7 years 4 years 1 year| 7 years years 1-1/2 years 6 months| 4 years 1-1/2 years 9 months 3 months| 9 months 4 months 3 months 2 months| * Light Duty: Motors operate infrequently (1 hour/day or less) as in portable floor sanders, valves, door openers. * Standard Duty: Motors operate in normal applications (1 or 2 work shifts). Examples include air conditioning units, conveyors, refrigeration apparatus, laundry machinery, woodworking and textile machines, water pumps, machine tools, garage compressors. * Heavy Duty: Motors subjected to above normal operation and vibration (running 24 hours/day, 365 days/year).Such operations as in steel mill service, coal and mining machinery, motor-generator sets, fans, pumps. * Severe Duty: Extremely harsh, dirty motor applications. Severe vibration and high ambient conditions often exist. * EXCESSIVE FRICTION: Misalignment, poor bearings and other problems in the driven machine, power transmission system or motor increase the torque required to drive the loads, raising motor operating temperature. * ELECTRICAL OVERLOADS: An electrical failure of a winding or connection in the motor can cause other Windings or the entire motor to overh eat. Noise and VibrationNoise indicates motor problems but ordinarily does not cause damage. Noise, however, is usually accompanied by vibration. Vibration can cause damage in several ways. It tends to shake windings loose and mechanically damages insulation by cracking, flaking or abrading the material. Embrittlement of lead wires from excessive movement and brush sparking at commutators or current collector rings also results from vibration. Finally, vibration can speed bearing failure by causing balls to â€Å"brinnell,† sleeve bearings to be pounded out of shape or the housings to loosen in the shells.Whenever noise or vibrations are found in an operating motor, the source should be quickly isolated and corrected. What seems to be an obvious source of the noise or vibration may be a symptom of a hidden problem. Therefore, a thorough investigation is often required. Noise and vibrations can be caused by a misaligned motor shaft or can be transmitted to the motor from the d riven machine or power transmission system. They can also be the result of either electrical or mechanical unbalance in the motor. After checking the motor shaft alignment, disconnect the motor from the driven load.If the motor then operates smoothly, look for the source of noise or vibration in the driven equipment. If the disconnected motor still vibrates, remove power from the motor. If the vibration stops, look for an electrical unbalance. If it continues as the motor coasts without power, look for a mechanical unbalance. Electrical unbalance occurs when the magnetic attraction between stator and rotor is uneven around the periphery of the motor. This causes the shaft to deflect as it rotates creating a mechanical unbalance. Electrical unbalance usually indicates an electrical failure such as an open tator or rotor winding, an open bar or ring in squirrel cage motors or shorted field coils in synchronous motors. An uneven air gap, usually from badly worn sleeve bearings, also pr oduces electrical unbalance. The chief causes of mechanical unbalance include a distorted mounting, bent shaft, poorly balanced rotor, loose parts on the rotor or bad bearings. Noise can also come from the fan hitting the frame, shroud, or foreign objects inside the shroud. If the bearings are bad, as indicated by excessive bearing noise, determine why the bearings failed.Brush chatter is a motor noise that can be caused by vibration or other problems unrelated to vibration. WINDINGS: Care of Windings and Insulation Except for expensive, high horsepower motors, routine inspections generally do not involve opening the motor to inspect the windings. Therefore, long motor life requires selection of the proper enclosure to protect the windings from excessive dirt, abrasives, moisture, oil and chemicals. When the need is indicated by severe operating conditions or a history of winding failures, routine testing can identify deteriorating insulation.Such motors can be removed from service and repaired before unexpected failures stop production. Whenever a motor is opened for repair, service the windings as follows: 1. Accumulated dirt prevents proper cooling and may absorb moisture and other contaminants that damage the insulation. Vacuum the dirt from the windings and internal air passages. Do not use high pressure air because this can damage windings by driving the dirt into the insulation. 2. Abrasive dust drawn through the motor can abrade coil noses, removing insulation. If such abrasion is found, the winding should be revarnished or replaced. . Moisture reduces the dielectric strength of insulation which results in shorts. If the inside of the motor is damp, dry the motor per information in â€Å"Cleaning and Drying Windings†. 4. Wipe any oil and grease from inside the motor. Use care with solvents that can attack the insulation. 5. If the insulation appears brittle, overheated or cracked, the motor should be revarnished or, with severe conditions, rewou nd. 6. Loose coils and leads can move with changing magnetic fields or vibration, causing the insulation to wear, crack or fray. Revarnishing and retying leads may correct minor problems.If the loose coil situation is severe, the motor must be rewound. 7. Check the lead-to-coil connections for signs of overheating or corrosion. These connections are often exposed on large motors but taped on small motors. Repair as needed. 8. Check wound rotor windings as described for stator windings. Because rotor windings must withstand centrifugal forces, tightness is even more important. In addition, check for loose pole pieces or other loose parts that create unbalance problems. 9. The cast rotor rods and end rings of squirrel cage motors rarely need attention.However, open or broken rods create electrical unbalance that increases with the number of rods broken. An open end ring causes severe vibration and noise. TESTING WINDINGS Routine field testing of windings can identify deteriorating ins ulation permitting scheduled repair or replacement of the motor before its failure disrupts operations. Such testing is good practice especially for applications with severe operating conditions or a history of winding failures and for expensive, high horsepower motors and locations where failures can cause health and safety problems or high economic loss.The easiest field test that prevents the most failures is the ground-insulation or 127 megger test. It applies DC voltage, usually 500 or 1000 volts, to the motor and measures the resistance of the insulation. NEMA standards require a minimum resistance to ground at 40 degrees C ambient of 1 mega ohm per kv of rating plus 1 mega ohm. Medium size motors in good condition will generally have mega ohmmeter readings in excess of 50 mega ohms. Low readings may indicate a seriously reduced insulation condition caused by contamination from moisture, oil or conductive dirt or deterioration from age or excessive heat.One megger reading for a motor means little. A curve recording resistance, with the motor cold and hot, and date indicates the rate of deterioration. This curve provides the information needed to decide if the motor can be safely left in service until the next scheduled inspection time. The megger test indicates ground insulation condition. It does not, however, measure turn-to-turn insulation condition and may not pick up localized weaknesses. Moreover, operating voltage peaks may stress the insulation more severely than megger voltage.Experience and conditions may indicate the need for additional routine testing. A test used to prove existence of a safety margin above operating voltage is the AC high potential ground test. It applies a high AC voltage (typically, 65% of a voltage times twice the operating voltage plus 1000 volts) between windings and frame. Although this test does detect poor insulation condition, the high voltage can arc to ground, burning insulation and frame, and can also actually ca use failure during the test. It should never be applied to a motor with a low megger reading.DC rather than AC high potential tests are becoming popular because the test equipment is smaller and the low test current is less dangerous to people and does not create damage of its own. CLEANING AND DRYING WINDINGS Motors which have been flooded or which have low megger readings because of contamination by moisture, oil or conductive dust should be thoroughly cleaned and dried. The methods depend upon available equipment. A hot water hose and detergents are commonly used to remove dirt, oil, dust or salt concentrations from rotors, stators and connection boxes.After cleaning, the windings must be dried, commonly in a forced-draft oven. Time to obtain acceptable megger readings varies from a couple hours to a few days. BRUSH AND COMMUTATOR CARE Some maintenance people with many relatively trouble-free AC squirrel cage motors forget that brushes and commutators require more frequent routin e inspection and service. The result can be unnecessary failures between scheduled maintenance. Many factors are involved in brush and commutator problems. All generally involve brush sparking usually accompanied by chatter and often excessive wear or chipping.Sparking may result from poor commutator conditions or it may cause them. The degree of sparking should be determined by careful visual inspection. The illustrations shown in Fig. 5 are a useful guide. It is very important that you gauge the degree number as accurately as possible. The solution to the problem may well depend upon the accuracy of your answer since many motor, load, environmental and application conditions can cause sparking. It is also imperative that a remedy be determined as quickly as possible. Sparking generally feeds upon itself and becomes worse with time until serious damage results.Some of the causes are obvious and some are not. Some are constant and others intermittent. Therefore, eliminating brush sp arking, especially when it is a chronic or recurring problem, requires a thorough review of the motor and operating conditions. Always recheck for sparking after correcting one problem to see that it solved the total problem. Also remember that, after grinding the commutator and properly reseating the brushes, sparking will occur until the polished, brown surface reforms on the commutator. Figure 5. Degrees of Generator and Motor SparkingNOTE: Small sparks are yellow in colour, and the large sparks are white in colour. The white sparks, or blue-white sparks, are most detrimental to commutation (both brush and commutator). First consider external conditions that affect commutation. Frequent motor overloads, vibration and high humidity cause sparking. Extremely low humidity allows brushes to wear through the needed polished brown commutator surface film. Oil, paint, acid and other chemical vapours in the atmosphere contaminate brushes and the commutator surface. Look for obvious brush and brush holder deficiencies: 1.Be sure brushes are properly seated, move freely in the holders and are not too short. 2. The brush spring pressure must be equal on all brushes. 3. Be sure spring pressure is not too light or too high. Large motors with adjustable springs should be set at about 3 to 4 pounds per square inch of brush surface in contact with the commutators. 4. Remove dust that can cause a short between brush holders and frame. 5. Check lead connections to the brush holders. Loose connections cause overheating. Look for obvious commutator problems: 1. Any condition other than a polished, brown surface under the brushes indicates a problem.Severe sparking causes a rough blackened surface. An oil film, paint spray, chemical contamination and other abnormal conditions can cause a blackened or discolored surface and sparking. Streaking or grooving under only some brushes or flat and burned spots can result from a load mismatch and cause motor electrical problems. Grooved commutators should be removed from service. A brassy appearance shows excessive wear on the surface resulting from low humidity or wrong brush grade. 2. High mica or high or low commutator bars make the brushes jump, causing sparking. 3.Carbon dust, copper foil or other conductive dust in the slots between commutator bars causes shorting and sometimes sparking between bars. If correcting any obvious deficiencies does not eliminate sparking or noise, look to the less obvious possibilities: 1. If brushes were changed before the problem became apparent, check the grade of brushes. Weak brushes may chip. Soft, low abrasive brushes may allow a thick film to form. High friction or high abrasion brushes wear away the brown film, producing a brassy surface. If the problem appears only under one or more of the brushes, two different grades of brushes may have been installed.Generally, use only the brushes recommended by the motor manufacturer or a qualified brush expert. 2. The brush holder may have been reset improperly. If the boxes are more than 1/8†³ from the commutator, the brushes can jump or chip. Setting the brush holder off neutral causes sparking. Normally the brushes must be equally spaced around the commutator and must be parallel to the bars so all make contact with each bar at the same time. 3. An eccentric commutator causes sparking and may cause vibration. Normally, concentricity should be within . 001†³ on high speed, . 002†³ on medium speed and . 04†³ on slow speed motors. 4. Various electrical failures in the motor windings or connections manifest themselves in sparking and poor commutation. Look for shorts or opens in the armature circuit and for grounds, shorts or opens in the field winding circuits. A weak interpole circuit or large air gap also generate brush sparking.

Pink is for Girls, Blue is for Boys

Pink is for Girls, Blue is for Boys: The Cultural Change in Gender Throughout HistoryThis essay will address the issue of culture, the media and gender and how they affects us in today’s society. â€Å"The generally accepted rule is pink for boys, and blue for the girls,† noted an article published in the Ladies Home Journal in 1918. Society, the media and gender role socialization have changed since the early part of the twentieth century. Gender differences have influenced men and women’s behaviours, thoughts and feelings since the early 1900s.A large part of this is because of how the media tells us we should act. Girls, for example, are traditionally seen as emotional nurturers and boys are seen as rough or tough providers and the breadwinner for the family. Since the moment of birth in the hospital, we are thrust into these gender roles – pink blankets for baby girls and blue blankets for baby boys. The constant changing ways of our society and the me dia is fascinating. The media provides us with an outline of how we should go about things in our daily lives. It also influences us on just about everything that we deal with on a day to day basis.Our social interactions, for example, our beliefs, and our influences on others are all shaped to some degree by society and the social pressures we feel. Media and gender roles have appeared for a long time in our society and that people follow them because they are comfortable with them and it is what we know. It’s unfortunate because so much of society abides by certain rules that the small population of us that do not follow those rules, get judged and shunned by the rest of society because they are different – most of us view that if something is â€Å"different† it is wrong.Gender roles, in turn, provide us with a sense of who we are, what we should do and how we should go about doing it. They also provide us with a false sense of reality. The more and more our society and culture changes, the more and more â€Å"traditional† views are pushed aside. For instance, not all women are effeminate and not all men conform to traditional concepts of masculinity. The stereotypical portrayals of gender roles on television and in the media, have gradually changed over the years, although not to the extent that society still sees as practical. Although women are beginning to berepresented in more occupations, men are rarely represented in ‘traditional' female roles, such as the nurturing child care provider or attending to the housework; this is still seen as a women‘s job. However, with society changing more and more every day, we see more women in the workplace, more men taking on a role in the home, and women (and men) spending more time in school to get a higher education in order to provide for their families. All of these factors lead to changes in our gender roles and it goes to show how quickly our culture and society consis tently change.Although the media has improved greatly in the past few years. Signorielli, a professor at the University of Delaware, argues that â€Å"[t]elevision can still be seen, therefore, as representing a distorted view of society, which the perceptive minds of children may pick up with ease† (70). This quote proves the fact that from the beginning of childhood, children can pick up on social intimation and gender socialization. It starts in early childhood with children’s toys, the girls are encouraged to play with Barbie and the boys encouraged to play with trucks, and more masculine equipment.Overall, what matters the most here is that men and women are still misrepresented as their traditional stereotypes in the majority of mass media. This stereotype becomes rooted in our minds, and is passed on from generation to generation as an ample view of male and female gender roles. Although women are slowly gaining respect and equality in today‘s society, it is not uncommon to see men and women illustrated as equals, working along side each other in an evenly challenging setting. This is especially true in the workforce.

350- to 700-word essay comparing the similarities and differences Term Paper

350- to 700-word essay comparing the similarities and differences between virtue theory, utilitarianism, and deontological ethics - Term Paper Example In order to understand these principles better and understand how they can apply to real-life situations it is best to discuss the strengths and weaknesses of each individually and then highlight their commonalities and differences. Utilitarianism focuses on the idea that what is morally or ethically right is the course that results in the best possible consequences or what creates the greatest happiness among the larger portion. After all human beings work off of a pleasure principle in their actions and behaviors. This perspective is often found among big decision makers whose behaviors and decisions affect many (Fahey, 2012). Therefore the greatest happiness on the largest scale is being considered, as opposed to the needs of an individual. For example when we are with a group of 5 friends and each want the group to participate in different activities, therefore each member makes their case and the majority activity is chosen. This will not make the whole group happy but it will make the majority happy. Deontologists are dedicated to the idea of actions that are ethical are a result of a sense of duty. There is a staunch strictness to this ethical viewpoint. An action is right as long as it remains in accord ance with preset ethical laws (Rainbow, 2002). A good example is what we see in modern court rooms today, sometimes the law is immutable and disallowing of exception, this takes no consideration of the larger groups concerns or the ethical concerns of the accused. The final ethical principle is virtue ethics, which adheres to the idea that a person’s individual character must be considered as exactly that individual. A prime example of this can be found in our own academic institutions. A friend forgets to properly site a source in his paper, which means he technically plagiarized. However, if you see that the other citations are accurate and this student has had no history of dishonest conduct,

Harvard Business Review Article Essay Example | Topics and Well Written Essays - 2500 words

Harvard Business Review Article - Essay Example Following seven key lessons will emphasize on the significant aspects of effective strategic leadership as learnt and comprehended by a student. Key Lesson 1: Maintaining Effective Communication Communication of the organization's purpose is one of the most vital aspects to be considered. A corporate organization's purpose of being is what it stands for and gives an overview of the main aims it wants to achieve. So, it is essential for effective strategic leadership of a corporate organization to state clearly its mission and vision. This can be explained lucidly by the mission statement of Google, which is to organize all the information in the world in a systematic manner so that it can be accessed and utilized universally. Moreover, the brand name of a company should be a direct reflection of its core values, so that the customers would be aware of the services being provided and being attracted to avail them at the same time. Richard Reed, Co-founder of Innocent, did an exceptional job at coming up with the brand name. Innocent; which is one of the most recognized and acclaimed brand in the UK, produces healthy fruit juices and food items only. The company's name, Innoce nt goes hand in hand with the word natural, which depicts the very nature of innocent products. Key Lesson 2: Sustaining Competitive Market Advantage Another important lesson is to sustain competitive advantage in the market over the passage of time. Skimming, price war, and predatory pricing etc. are some of the marketing techniques which could be utilized by the company to sustain the advantage or to drive their competitors out of the market completely. If this upper-hand advantage is not achieved and sustained, a company could face serious consequences, which reflect adversely on its strategic leadership policies. The downfall of PepsiCo is one of the examples of this scenario as Indra Nooyi, the current chairman and CEO of PepsiCo, is facing a loss of market shares and decreasing stock values due to failure at sustaining competitive advantage with rival beverage company Coca Cola. In an announcement made in February, 2012, it was revealed that due to its financial concerns, PepsiCo is cutting down 8,700 employees. The company is starting new lines of diet soda and sugar free products to increase the customer interest but this strategy has not been very successful due to the launch of similar product lines from rival companies. PepsiCo is trying to devise new product lines in order to obtain competitive market advantage so that it can be successful in the market again. Indra Noooyi is also feared to be terminated from her current position of the CEO of the company if the financial position of the company does not stabilize. Key Lesson 3: Effective Change Management Faslane Naval Base was run entirely by the Ministry of Defence of UK and the Royal Navy up until 2002. Afterwards, a contract was signed with Babcock Marine to reduce the cost and to improve operational efficiency. The staff had to work under a different managing authority with new aims and futuristic goals. John Howie, director of Babcock Marine, set forth the emphasis on delivering services to the Navy, eradicating the previous goals of focusing on building infrastructures. Effective strategic leadership could never be achieved without effic ient and timely change management in the organization. Faslane is an organization where the only assets are the people, so to implement change, the shackles which bound the workers, had to be eliminated. Starting with low level managerial changes, the company moved towards gaining efficiency by re-engineering fundamental processes to

Language Portfolio Essay Example | Topics and Well Written Essays - 2000 words

Language Portfolio - Essay Example It is always within my reach. My native country in Russia is where it all started. I became conscious of my existence in a place where the struggle for social steadiness is of great importance. It is the place where I became oriented with a cynical outlook in life while at the same time it enabled me to anticipate and understand any difficulties I encounter in life. Because of such view point, moving to Istanbul a few years ago became a welcoming experience for me. The shift in adjusting from Russian to Turkish culture became a needed challenge for me. Living in Turkey opened my doors to the convergence of cultures between the East and West. It allowed me to reflect on the hybrid between Western and Eastern influences. It opened my eyes to the cultural differences I have witnessed around me. Eventually, I decided to move into the United States only to immerse myself in a multi-cultural surrounding. While I experienced various intercultural encounters from my global travels, I sought to find a place where my love for culture and the arts will be satisfied. Because of this intense interest to retrace my European heritage and culture, I have looked up to the French language to equip me with better understanding of human creativity that I see in French cinema, literature, and arts. My various trips to France were always field with memorable moments that fueled my interest and love for humanities. As such, my motivation to learn French is deeply rooted from my appreciation of the country and its culture. As my future journey to live in France awaits me, I never cease to continuously the language. A Question of Identity: What it would mean for me to be a fluent speaker of French Learning French has always entailed a more personal than practical reasons to master the language. It cannot be denied that my motivation to learn French mainly comes from my appreciation of the culture in general. I learn French not only because it entails various opportunities in working fo r international organizations abroad, but also because it means that I am able to associate myself with French culture. Many might wonder why I exhibit such love for the language, but I can only tell them that I have been to many places around the world and while each country showcases a unique cultural heritage, I would say that in terms of music, architecture, movies, and literature, the French culture exhibits a more lively appreciation for the arts. Perhaps the word I should use in describing the French is sophistication. My various travels to France have always been memorable as I was able to appreciate the heritage and the undying affinity of the French people towards arts and literature. Personally, I want to live in this kind of setting where I could revel on the French countryside and associate with the like-mindedness I shared with French people. For these reasons, becoming a fluent speaker of French allows me to understand and penetrate in French society. A lot of friends whom I treasure deeply are French and to be able to gain more meaningful experiences with them, I am determined to hone

Assisting Palestine Refugees Essay Example | Topics and Well Written Essays - 2750 words

Assisting Palestine Refugees - Essay Example Thus the Palestinian refugees were scattered through the different locations where their presence is still seen today. In June 2002, US President George W. Bush formally committed US support to the creation of an independent Palestinian state that would be established on the West Bank and Gaza Strip. This was further bolstered by the pronouncement by Israeli Prime Minister Ariel Sharon, in the 2004 Likud convention, that â€Å"If a new Palestinian Authority is established, free of terror, if the incitement stops, the Israeli government led by the Likud will be prepared to carry out its part to make possible the establishment of an independent Palestinian state† 2 In January 2009, Israel ended a three-week military operation in the Gaza Strip that killed 1,200 Gaza residents and 5,000 wounded. During the military assault, civilian housing, public infrastructure, and most importantly medical facilities suffered serious damage, with thousands left homeless. A subsequent UN fact-finding mission recommended that international legal action be taken against Israel and Hamas for alleged war crimes and what may be crimes against humanity; however, as of the end of 2009, the UN Security Council has not yet acted on the recommendation.3 Meanwhile, Israeli pursued a policy of restricting movement of people and goods through the borders of the Gaza Strip, which has stifled economic activity and impeded territorial reconstruction. Restrictions were slightly relaxed in the West Bank; however, economic progress, settlement building, and reconstruction were all the same impeded, while incidences of settler violence against Palestinians still broke out. 4 It is against this backdrop that the case of Palestinian refugees is to be analyzed. The refugee situation shall be described by assessing the rights and obligations of the host state vis-à  -vis the refugee, the capability and nature of short-term and long-term responses, the role of international civic organizations in refugee response, and the prospects for successful repatriation and reconstruction.

Measurement Essay Example | Topics and Well Written Essays - 500 words

Measurement - Essay Example neers observe measurements, why measurements are much needed in the world, the role of measurements in quality control, and different type of measurements techniques used in engineering will be discussed. The term â€Å"measurement† is derived from the Greek word metron which means limited proportion. The first measurement systems were astronomical objects. Babylonians and Egyptians are believed to have invented use of measurement. However, they mainly used comparisons to measure things. For example, they would compare capacity of containers by filling the smaller container and emptying it into the bigger one to measure the volumes (Manseau & Shields, 2005). However, Gabriel Mouton, who was an astronomer, invented the metric system. He also suggested the swing length of pendulum, which is used as a unit of measuring length. In engineering and construction, there are different metric systems depending on what is being measured. For example, construction materials that are in liquid form are measured using measures such as gallons and liters. In case of length, units such as inches, meters, and feet are used depending on the size being measured. While measuring mass, unit such as pounds, kilograms, and grams are applied (Manseau & Shields, 2005). Although scientists make use of standardized metric units, there are two different types of metric systems. The type of metric system being used depends on the application. When measuring small units of length or mass, engineers make use of the CGS (centimeter-gram-second) system. However, MKS (meter-kilogram-second) system is used while measuring large quantities (Manseau & Shields, 2005). With globalization, metric system is becoming widely acceptable worldwide though some countries such as United States are resistant to switch to the metric system. US makes use of a mixture of different systems of measurement. In 1960, the General Conference of Weights and Measures revised and simplified the measurement system. Seven

What is Politics Dissertation Example | Topics and Well Written Essays - 3750 words

What is Politics - Dissertation Example This research will begin with the statement that since time immemorial, politics has been a part of humanity from its the primeval conceptualization up to its modernized encapsulation. Politics existed even before the government, democracy, state and et al came to its realization. During the primordial state of man, chaos is everywhere due to the stiff competition for survival. Man lives in an inevitable partition against other individuals to secure territory, food, and property. Decentralization is the embodiment of man’s primitive status quo. The schematization of centralization and planning arise to curb the catastrophic nature of man and to reconstruct the operation of politics within man’s disorganized society. Innumerable treatises, social contracts, and laws were enacted to guarantee that man’s nature and society will actualize a perpetual order and peace. The discussion of centralization and planning was only given enough attention during the twentieth ce ntury to provide a nitty-gritty exposition of how politics should operate. Several stereotypes have been attached to the word politics. Most people think that politics is an embodiment of corruption and shenanigans among officials. And others usually associate this term with government, administration, bureaucracy, politicians and the likes. In order for us to achieve a definitive definition of politics, it is a necessity to utilize a systematic approach. The first task is to outline the historical encapsulation of politics starting from its origin and its primeval understanding.

Research6 Essay Example | Topics and Well Written Essays - 500 words

Research6 - Essay Example The â€Å"Honeyed Nougat Miracle† is extremely significant in the Rainbows End since it highlights some of the delusions that will be part of the upcoming digital technologies that the reader may need to take caution upon (Vinge 4). Vinge highlights the reactions of Dr Xiuxiang and Robert Gu on the label â€Å"No user serviceable parts within†, boldly embedded on the black boxes (literally to imply the encapsulated forms of the technological devices hardware and software) that were complex and permanently fixed (they could not be altered or replaced). Gu and Xiuxiang were perplexed because the black boxes were not operating as they needed them to and still were unable to change or replace them(Vinge 58). Robert Gu was astounded by the life-prolonging technologies which restored his health back to normalcy after battling with Alzheimer (Vinge 52). The phrase â€Å"that was the genius insight of this dark morning, the conclusion he had evaded every day since he was brought back from the dead† reveal the convenience and intelligence accompanying the contemporaneous technologies was astounding. For instance, Robert Gu’s health was restored in a flash (which he calls magic), and he regained his youthful body once again. At the moment, many competent professionals have crowded the job market and, as a result, the selection criteria for selecting candidates for specific careers has diversified, leaving many qualified candidates below the expected cut off specifications. In addition, as many global activists push for minimal wage increase, vast employment seekers have key preferences for the careers they seek in the job market (such as the jobs which match what they studied in college). Their preferences may, unfortunately, be unavailable in the job market and therefore ending up being jobless. Also, most careers need diverse skills. These skills are constantly changing for distinct, unique careers. Most employees, unable to cope with the changing

Blood Brothers Essay Example for Free

Blood Brothers Essay You are the director of a new production of blood brothers. Give advice to the actors playing the roles of Eddie and Mickey about how to tackle the age changes. You must comment on at least two scenes in detail. If you have seen a production of Blood Brothers you may also refer to this. In the scene when you both meet for the first time you must consider your body language. You must consider how an eight year old would walk and stand. An eight year old would have fewer worries than someone who is older than them so they would walk not really paying much attention to what is around them. You would also have to think how someone who is better off would walk compared to someone who is from a less well off background. You have got to consider how to use the tone of your voice. At first they were a bit shy. But after they first met you would have to consider how an eight year old would not be shy so they would say anything so say your lines so the audience have no clue to what you will say next. Another important factor to consider is the way you deliver your lines. You should deliver your lines in a free flowing way. When they are swearing you should not feel like people might be offended. In the scene when you Mickey and Eddie meet for the first time after they have both moved to the country you should pay attention to your body language. This time Eddie and Mickey are both 16 17 years olds. So you have to think about how a 16 17 year old would act. A 16 17 year old would have more problems than a person of 8 years old but still not as many as an older person. You still have to consider how a person who is better off would act compared to a person from the ghetto. Again you would have to consider the tone of your voice. You would expect a teenager to swear more and they may speak with a slight mumble. Again you should consider the way you deliver your lines. In the scene when Mickey is trying to kill Eddie you should again pay attention to your body language. This time Eddie and Mickey are both in theyre thirtys. Mickey is depressed and he has a lot of problems an example of which was that he was put in jail for his brother shooting someone. While Eddie on the other hand has few, because he has a successful business. Mickey has just realised that Eddie is seeing his girlfriend Linda. When Mickey is pointing the gun at Eddie, Eddie has to act scared because he fears for his life. Mickey is holding the gun so that he feels in control instead of having Eddie control his life. Mickey has to act confused because Eddie made his life; he gave him a job and a nice home. You again have to consider the tone of your voice. Mickey should say his lines in a sort of stuttery way. Eddie should deliver his lines in a scared voice, while Mickey should deliver his lines in a scared and confused way.

Boeing Vs. northrop Essay Example for Free

Boeing Vs. northrop Essay In March 2002, the US airforce selected Boeings KC-767 on the grounds that it had clearly demonstrated the abilities to meet their requirements. The United States Airforce (USAF) in their acceptance statement brought out four points that they cited as being behind their decision (CBS News, 2008). The Boeings design was designated KC-767A and was included in DODs 2004 model designation report. Approximately 100 KC-767 tankers were leased from Boeing for the air refueling program. Even though the refueling program was in place in many countries in the US, many had questions about its effectiveness and cost implications especially the idea of leasing crafts which may never have any buyer once the lease period was over. This argument brought forward by senator McCain was however countered by the number of US allies who were more than willing to buy their used crafts (CBS News, 2008). The congressional budget office was next in line as they criticized the budget stressing on its fiscal irresponsibility (United States Government Accountability Office, 2008). This led to the striking of a deal where the state would buy 80 KC-767 and lease twenty (United States Government Accountability Office, 2008). However, in December of 2003, the pentagon announced that the project had to be frozen due to a corruption allegation brought against one of its former staffer (CBS News, 2008). Furthermore, documentations that proved that the A330 based tankers were more suited to the task specifications of the airforce were more cost effective relative to Boeing tankers were found (CBS News, 2008). The scandal led to the sentencing of the culprit who pleaded guilty to corruptions and led to the resignation of Boeings CEO. Donald Rumsfeld in 2006 announced the cancellation of the KC-767A leases as a measure aimed at cutting the costs and a redefinition of the USAF mission (United States Government Accountability Office, 2008). The defense secretary further stated that the move will not in any way affects the mission of the KC-767A as the upgrade of the KC-135s fleets will help in moving towards the goals (United States Government Accountability Office, 2008). However, the development did no affect the relationships between Boeing and its other customers. The development were however short lived and Boeing and Northrop were soon back in the ring fighting for a big defense contract. The basis of Boeings arguments was that the KC-30 was more versatile and had a large furl capacity than the KC-135 that were being used by the airforce. The KC-135 was developed by Boeing who were bidding for an airforce contract against their nemesis Northrop Grumman . The latter won this round of battle as the departments of defense announced that it has won the tender to procure 179 new KC-45A tankers (Online News Hour, 2008). The Boeing company almost immediately took to the Government Accountability Office and filed a protests claiming the evaluation of its KC-30 was unfair (Online News Hour, 2008). Boeing further claimed that its refueling tanker could easily be reconverted to a passenger plane compared to Northrops version as shown in the Air forces post decision briefing. According to Boeings vice president they had more strengths than their competitors was all he heard from the post decision briefing. Boeings protests led to a review of the selection process by the accountability office which forced Northrop to freeze the project which it had already allocated $ 35 billion (Online News Hour, 2008). Northrop Grumman executives are on the other hand highlighting the irresponsibility involved in freezing a critical project to the development of the military for expensive lobbying in the congress that will inevitably lead to a change of the decisions made by the airforce (Online News Hour, 2008). Northrop Grumman executives further claim the decision is ironic since they put their best efforts in ensuring that the airforce receives a products that they consider the best in consideration of the design (Online News Hour, 2008). They are pushing for the public knowledge of the facts of what they represents and what they are not. The congress was divided sharply on this issue and so was the general public. Boeing supporters claim that the Northrop Grumman design was a basic passenger airbus plane (Online News Hour, 2008). A Kansas congress man was cited claiming that the decisions made by the airforce was a bad one as the airforce as it has bend backwards to deal with a French company (Online News Hour, 2008). Boeings die hards near its main production facility claimed that it is the only true tanker manufacturers and a mistake had been made (Online News Hour, 2008). A Washington senator supported this point of view and claimed that offering a military contract to a foreign company was suicidal and would incapacitate Americas ability to develop their own fleet if they should ever pull out of the deal (Online News Hour, 2008). An Alabama state senators is of a different view and approached the subject from a resource allocations view point (Online News Hour, 2008). People near Northrop are bound to benefit more that those near the Boeing plants and therefore there senators have opinions that display their satisfaction or dissatisfaction with the resource allocations (Online News Hour, 2008). She further states that there have to be losers and winner either way (Online News Hour, 2008). The Boeing group further accuse the airforce of a change in parameter in order to accommodate the design put up by Northrop Grumman so as to ensure two bidders are present (Online News Hour, 2008). Even though many are of the view that the airforce was trying to lock out Boeing due to the scandals it previously had, Boeing executives were of the view that was not the case as the specifications that were asked by the airforce were changed considerably to ensure Northrop was in the race (Online News Hour, 2008). They further claim that the large sized tanker proposed by the Northrop was a liability and only countries not interested in their taxi ways would allow for such aircrafts. The Northrop group however counter this argument by stating that their design is more sophisticated and has advantages that are yet to be seen (Online News Hour, 2008).

Stakeholder Project Organization

Stakeholder Project Organization The Stakeholder would be someone who is concerned, an engaged or interested in a project. Stakeholder is individuals or organizations that have a straight concentration in a service being provided. There are three categories of user primary, secondary and tertiary. Example: Employees, customers, suppliers, Local community. 1.1 .1 PRIMARY STAKEHOLDERS: Primary stakeholders are those people and groups ultimately who are affected by the project. That will be differ depends on the types of project concerned and should be analyzed according to criteria such as gender, income levels, dependence on resources, etc. The primary stakeholders are the most important of the organization. People or group who are ultimately impacted either positively (beneficiaries) or negatively (for example, competitors). The users are those likely to be frequent hands on user of the organization. Example Regional Nature Conservation Authority Ministry of Environment, Forestry, Regional Planning, etc Activity:- Landowner and or residents in the forest Forestry companies Tourism operator Recreational and other user 1.1.2 SECONDARY STAKEHOLDER: Secondary stakeholders are the intermediaries in the aid delivery process. The secondary users are occasional user or those who use the system through an intermediary. People or groups who have a role in the decision making process without being directly affected by the outcome. Example Local business Landowner and residents not inside the protected area but near Environment NGOs 1.1.3 TERTIARY STAKEHOLDER: Tertiary users are those affected by the introduction of the system, or who will influence its purchase. Tertiary stake holder can still have an influence, but are not directly involved. Example Local opinion leader Local media Ecological department of universities, research institutes Environmental inserts or special programs of national media 1.2. Scope Document: The scope document is a general term for any document that refines and defined the requirements aspect of the triple constraint of time, cost, and requirements. 1.2.1 Purpose of a scope document: The purpose of this document is to collect, analyze, and define high-level needs and features of that system. It focuses on the capabilities needed by the projects. The scope statement is generally confined to a few paragraphs or pages, the scope document may be a far more substantial document. It captures information from a variety of sources and places it in a single repository. As an alternative, it may largely be a document that provides reference to other documentation in other locations. Specifically identifying those locations and the information embedded in that documentation. 1.2.2 Contents of a scope document: Executive Summary: It contains the overall information about the project in a short summary documentation. Description of the Proposed Action The various types of action and processes will be taken to accomplish the project. The description of all those action and processes is documented here. Project Purpose, Need and Benefits Background and History of project Cornell and Public Need for the Proposed Action Objectives of the project Benefits that will be gain to meet the objective. Neighborhoods Consideration about the business competitors, about their activity. Project Deliverables Description of all deliverables that will establish the successful completion of the project Project Boundaries The project development area is defined here with specifications. Resource needs The resource that will be needed to complete the project successfully, all are documented here. Cost Contain specific plan about the cost estimates to prevent misunderstanding later. Payment plan Define when and how project development team should be paid for the project Task-2 Introduction: There are some visual forms to help us our project. There are different stages in the development of the project and that stage can focused to use some visual form. While planning to develop a project many factors and issues should be considered before getting into the project and what are more stages in the total life cycle is vital for the successful implementation of the project and that stages are focused by the visual form. You can focus of all your project stage by using visual form. 2.1 Life Cycle Model:- The term project lifecycle models how a project is planned controlled and monitored from its inception to its completion. Project life cycle model are not similar. To deliver a quality system, its critical to know the risk facing your project and to use models that reduce those risks. Life cycle models describe the phase of the projects and the order in which those phase are executed. Each phase produce deliverables required by the next stage in the life cycle. There are some life cycle models is Waterfall Model, V-shape model, Spiral model and etc. 2.1.1 Waterfall Life Cycle Model: The waterfall life cycle was the first attempt at the definition of software development life cycle. The concept of a waterfall in this model suggests that one stage is completed before the next one starts and the diagram exactly show that concept. Stage completion is judged by the outcome of the stage matching the requirements defined by the previous stage. Requirements Analysis Diagram: Waterfall Model Requirements Specification System Design Code Test Implement Maintenance The water model is very simple diagram. The model is showing some lifecycle activities. The waterfall model is very simple to use and easy to manage due to the inflexibility of the model because each stage has specified deliverables and a review processes. Those stages are completed one at a time. That is best for small project where requirement are much understood. 2.1.2 V Model: The life cycle models heart of the v-Model. It describes the activity and products in the V-Model. Just like the waterfall model, the v-shaped life cycle is a sequential path execution of processor. Each stage must be completed before the next stage begins. Testing is emphasized in this model more so than the waterfall model though. The testing procedures are developed early in the life cycle before any coding is done, during each of the phase preceding implementation. Maintenance Initial Concept Requirements definition Software Design Detailed Design Code Unit Test Acceptance Test Integration and Test Tested Software Tested System Test Modules Diagram: The V Model The sequential lifecycle diagram is easy to understand, it easy to focus what the plan a project according to a sequential approach. The V-Model maintains the change control board and they meets once a year and processes all received change request on the V-Model. That supports tailoring, at each project starts, the V-Model is tailoring into a specific project. The tailoring makes it possible because the V-Model is organization and project independent. The V-Model produces actual support on how to implement an activity. In each activity scheme there are instructions, recommendation and detailed explanation of the activ 2.2. The Activity Networks: The activity network is a technique for pictorial representing a project plan. It shows dependencies between all the activities that have to be created. The most important part of activity diagram is the Critical path. Activity networks find out the all activity and find out who activity dependence to others. And the process of creating network begins with the drawings up of dependency list. The processes assign independence to each product or activity and specifies it backwards dependency. EST Duration EFT Activity Description LST Float LFT 8 5 13 E 19 11 24 22 2 24 I 22 0 24 24 4 28 J 24 0 28 28 28 3 5 8 C 14 11 19 3 6 9 G 18 15 24 9 13 22 H 9 0 22 13 7 20 F 15 2 22 9 4 13 D 11 2 13 0 3 3 A 0 0 3 3 6 9 B 3 0 9 0 0 Diagram: Activity Networks The activity networks show the activity by a box with sections used to hold key pieces of information. The show the activity starts time, finished time and there duration. They show last start time, finished time and there float. For example the boxes (nodes) A, B, C, D, E, etc represent the activities and the arrows, or connectors, represent the dependencies between the activities. And provide the information of which are activities are much more critical. The diagram contains the some visual information are: Earliest Start and Finished Time Latest Start and Finished Time The Critical Path Dependency Type 2.2.1 Earliest Start and Finished Time:- Earliest Start Time (EST): The earliest points are shown when the activities are started. The next activities (box) earliest start time (EST) dependence on previous finished time (EFT). Earliest Finished Time (EFT): the earliest point are illustrate the activities finished time. The EFT depends on what the activities duration. The activities duration calculate (EFT = EST + Duration) the EST and produce the Earliest Finished Time (EFT). 2.2.2 Duration: The diagram is show the activities duration. That is easy to find out which activities times are defined. The important point about this is that it is not until the activity network has been completed, and the dependencies combined with the estimated elapsed durations, that the project manager can be confident about the predicted elapsed duration and whether a specific end date is achievable or not. 2.2.3 Latest Start Time and Finished:- Latest Start Time (LST): They LST provide the information of the latest time that the activity in question can begin, without causing subsequent jobs to overrun. Latest Finished Time (LFT): The latest time that the activity in question can finish, without causing subsequent jobs to overrun. Float: The earliest points are show the time of who much needs to time the activity are finished. They use to some mechanism to provide the information. Working backward through the network, the mechanism is: LFT of an activity = LST of succeeding activity. LST of an activity = LFT Duration. 2.2.4 Critical Path:- The diagram (visual form) is very attractive you can easily find out which activities are critical. If any activity has no Float, as in the case you can understand that the activities are more critical and this called the Critical Path. That helps to the project. These activities are high risk, so The superlative people can put on them They can easily monitored frequently of the activity The estimating can be re-examined for their liability to any risk of overrunning. 2.2.5 Dependency Type: The visual form can easily help us to find out the dependency of our project activities. That can show to which activities are depending to other. â€Å"We have assumed that an activity cannot start until the previous one has finished. This is not always the case. Sometimes activities can overlap, for example, where one activity is design programs and the successor is code programs these can go almost on parallel but there must be delay before the start of the letter activity.† 2.3. Mind Maps:- â€Å"Mind Map is diagram used to represent an expression of radiant thinking and is therefore a natural function of human mind†. This visual form is very interesting that can generate an imaging idea of any projects. Mind Mapping is useful technique that improves the way you take notes, and support and enhances your creative problem solving. By using Mind Maps, you can quickly identify and structure of a subjects and the way that pieces of information fit together, as well as recording the row facts contained in normal notes. Mind maps are tools which help you think and learn. FIG: Mind Map 2.3.1 Key Ideas in a project: That is applied to every aspect of life where improved learning and clearer thinking will enhance human performance. The mind map has some essential characteristic: The subject of attention is crystallized in a central image The man themes of the subject radiate from the central image of branches Branches hold a key image/word printed on the associated line details radiate out The branches from a connected model structure Mind Maps are more compact than conventional note, often taking up one side of paper. This helps you to make associations easily. And if you find out more information after you have drawn the main Mind Map. Then you can easily add it in. Mind Map is also easily useful for: Can summarized information That can easily Consolidating information from different research sources Its help to thinking through complex problems and Presenting your information in a design that shows the overall structure of your subject Task-3 3.1. TUCKMAN Theory: Bruce tuckman has provided the theory to develop a successful project team. There have five stage of group development. His research led him to determine four phase of group development those are- Forming Storming Norming Performing And the last stage is Adjourning. Forming: personal relations are characterized by dependence in this stage. Storming: in this stage, the characterized by achievement and argument in the personal relations dimensions an organization in the task-functions dimension. Norming: in the stage, the interpersonal relations are characterized by cohesion. Performing: This stage are not reached by all groups, if group members are grow to stage four, their ability, variety, and depth of personal relation are expand to true interdependence. Adjourning: That stage involves the execution of task behaviors and disengagement from relationship. 3.2. BELBIN Theory: Dr Meredith Belbin defined a team role as: â€Å"A tendency to behave, contribute and interrelate with others in a particular way†. Belbin identified nine cluster of behaviors team, terms team role. Those are- Co-ordinator: the co-ordinator may not stand out in a team and usually does not have a sharp intellect. Shaper: He or She will challenge, argue or disagree and will display aggression in the pursuit of goal achievement. Two or three shaper in a group, according to Belbin, can lead to conflict, aggravation and in-fighting. Plant: Weaknesses are a tendency to disregard practical details and argumentativeness. Resources Investigator: Weakness are a tendency to lose interest after initial fascination with an idea, and they are not usually the source of original ideas. Company worker/implementation: Implementers are conservative, inflexible and slow to respond to new possibilities. Monitor evaluator: Weakness are that they appear dry and boring or even over-critical. They are not good at inspiring others. Those in high level appointments are often monitor evaluators. Team worker: They tend to be indecisive in moments of crisis reluctant to do things that might hurt others. Completer finishers: Weaknesses according to Belbin, are that they tend to be over anxious and have difficulty letting go and delegating work. Specialist: their weaknesses are single-mindedness and a lack of interest in other peoples. 3.3. MYERS_BRIGGS theory: The Myers-Briggs personality typology, unlike some other typing theories such as the Enneagram or Four Temperaments, uses a combination of several aspects to arrive at a â€Å"composite† type, based on the interaction and relative weight of different behavioural and attitudinal factors. The types are expressed as combinations of four letters, as follows: E or I (Extravert or Introvert) S or N (Sensing or iNtuitive) T or F (Thinking or Filling) J or P (Judging or Perceiving) E/I preference: interest the world around you. S/N preference: how you gather the information about the world. T/F preference: how you evaluate that information. J/P preference: your attitude to the world. These four pairs give 16 possible combinations, some of which are more common I the population than others. I will use myself as the worked example in what follows as I am the nearest subject to hand. 3.4. Knowledge from Tuckman, Belbin, and Myers-Briggs theory to develop a project team 3.4.1 Tuckman theory: Tuckman theories originally give me the knowledge of groups. How the way to observed group evolve, whether they were conscious of it or not. And I understand how to move the performed in the stage. The forming stage is describing the characters of each group members. And next stage they are comments to each other. Group might be happily Norming and performing stage because they are understood to each other. 3.4.2 Belbin theory: I collect the some information of Belbin theories. That is each team role has its particular strength and allow able weaknesses, and each has an essential contribute to make to a team. Every member needs different time to her/his roles. 3.4.3 Myers-Briggs: That theory simple to helps an aide-memoire for people who have done the profile, and give a flavor of how it works if its new to you. The theory helps to how we deal with the world around us. How you gather the information about the world and how you evaluate that information and your attitude. Generally if Im a project manager then I select and develop of an effective project team to follow some idea. First fall check every team members are polite behaviors and the members have more confident. And identifies the members are communicate more openly with each other and then I will make a project team. The members are keen to be accepted into team and look the team leader for guidance and direction. The members are eager to be accepted. 3.5. Risk of Team Failure: There are common problems:- 3.5.1 No Trust between the Team Members: That is most and effective problem to a group. When team members do not trust to each other or are suspicious of each others motives, the end result is a team that is not interrelated in its approach. So we are assessment the team members are related to each other. 3.5.2 Ineffective Interaction and Unproductive Team Meeting: Some of important time all team members comes to attend the meeting. The meeting is one of the most critical aspects of the team process with strategies and innovative to problems emerging during this time. 3.5.3 Poor Role Clarity: When roles are not clearly defined, this can lead to conflict and confusion on tasks. So team member can not understand what exactly is expected of each of them. So identify who is responsible to each tasks and identify they are confidently done this tasks. 3.5.4 Poor Time Management: A team should plan its goal and activities whilst keeping time constraints and deadlines in mind, otherwise their efficiency level in managing and implementing a task can suffer. While a team analysis any task they should define who many times are needed to each task. They are trying to finish that task proper time. 3.5.5 Losing Focus of Business Objective: If every member can unclear the goals of team so they lose of directions and lose of focus efficiency products. And turn lead to wrongly prioritized activities. While a team can identify their goals they can lead better direction and focus the efficient products. 3.5.6 Faulty Analysis of Market Conditions and Flawed Company Policies: If a team can fail to reservations in market condition 3.6. Risk Matrix: This is the simple method to raise visibility of risk and assist the management to make decision against all the risk that arise. It is a graphical representation of information normally found in existing risk logs. Risk matrix is easy to use, unless they are designed properly High Medium Low High Medium Low Consequence Likelihood A A A B B B C C C FIG: Risk Estimation Matrix (From MBP book of NCC Education) 3.6.1 Notes: How to assess the Risk of team failure. A risk assessment is simply a careful checking of what, and identify of any event that if occurred. It may be negatives or positives in our team. There are many reasons for a team can breakdown. So we are researched before making a team. That helps get greater strategic thinking and enhances creativity the proper solution when a team failure. 3.7. Contingency Plan: The contingency plan helps to identify what I will do if the risk occurs. The points are discussed here encapsulate the key issues that can lead to team failure. Team managers and team leaders have to take measures to protect the team from these chains that can wrap themselves around the team and collapse its performance. Diagnosing is the first step to solving the problem. Some of the issues such as role clarity or losing focus of business objectives can be solved by a discussion with the team members. Some of the other problems like poor trust, poor time management, and poor team interaction can be better tackled through team building exercises. Lets now look at the other side of the points, success. If success is what the team is after, then what is it that is expected of teams? What should they do to be successful? Understand their goals Interact, communicate effectively, explore ideas and innovative approaches Be loyal, co-operative, willing to share information and lend a helping hand Understand market realities and develop a sound strategy Keep time frames in mind Know their responsibility within the team and focus on results All this may seem like a tall order but is actually achievable. Everybody on a team is naturally equipped to deal with these factors, the only exception being ‘flawed company policies, which is up to corporate management to resolve. When teams in an organization show problems, then the solution may lie in a deeper analysis of the problem and exploring the areas mentioned above to find a solution. Task 4 Validation and Verification is the process of checking that the product. 4.1. Verification: 4.1.1 Definition: â€Å"Am I building the product right?† The process of determining whether or not the products of given phase of the software development cycle fulfill the requirement established during the previous phase 4.1.2 Purpose The purpose of Verification is to ensure that selected products meet specified requirements. The interpretation of this process area for business development is to ensure business development work products meet specified objectives and criteria. A key work product is the customer proposal. It should be verified that it meets customer-specified needs by conducting a readiness. 4.1.3 Importance: It is important to verify that the business development products meet the external customers needs. Verification increases the likelihood that offered products and services will be accepted by the customer, but it does not guarantee success. Verification is necessary but not sufficient. The business development campaign should include verification milestones throughout the process. Does the proposal meet the buyers specification? What are the risks in the proposal? Do marketing collateral and advertising meet the defined goals and objectives of the campaign? These types of question arise in a project for verification. 4.1.4 Features: verification addresses whether the work product properly reflects the specified requirements Verification includes verification of the product and intermediate work products against all selected requirements, including customer, product and product component requirements. Verification is inherently an incremental process because it occurs throughout the development of the product and work products, Verification of work products substantially increases the likelihood that the product will meet the customer, product, and product component requirements. 4.2. Validation: 4.2.1 Definition: Am I building the right product? Validation is the process that checks the product design satisfies and fits. That provides a high degree of assurance that a product, services, and system accomplished its intended usage â€Å"you built the right product†. There are few terms uses in validation process: Code validation/Testing Function validation/Testing User acceptance Testing or system validation 4.2.2 Purpose: The purpose of Validation is to demonstrate that a product fulfills its intended use when placed in its intended environment. The interpretation of this process area for business development is to validate and to demonstrate that a campaign product or service fulfills its intended use in support of the business development campaign objectives. 4.2.3 Importance: The proposal is a key product of the marketing effort. Prospective customers base their decisions largely on the organizations proposal. Because knowing how to develop a good proposal is critical core competency for business development, it is important to evaluate the readiness of the offer before it is submitted to the customer. The following types of question may in project for validation. What is the size of the market? Is the market growing or contracting? What influences this movement 4.2.4 Features: validation can be applied to work products as well as to the product and product components Validation is to demonstrate that a product or product component fulfills its intended use when placed in its intended environment. Validation demonstrates that the product, as provided, will fulfill its intended use 4.3. Verification and Validation in a Project Lifecycle The need and importance of verification and validation in a project are stated below with a life cycle model. The V-model Operation Test Stress Test Business Analysis Requirements Definition Functional Design Technical Design Programming Source Code Technical Design Functional Design System Requirements Business Requirements Live Simulation Acceptance Test System Test Link Test Unit Test Environment Test SPECIRYING TEST INTERMEDIATE PRODUCT VERIFYING SRAGE 4.3.1 Verification and validation in V model Here validation is taken in the primary stage which named requirements specification to check all the information in accurate and exact for build the project. With the information of previous stage the design stage is developed. Verification is done after the design process to develop evidence of design solution requirements compliance. A shorthand statement of the meaning of verification is commonly voiced as, â€Å"Am I building the product right?† Verification technique aims to detect and aid the designer to correct mistake during the product developments.. After the design is verified, the conceptual model and its associated design are converted into code or hardware by the developer. Code verification and hardware checkout ensure that the detailed design is being implemented correctly in the code or hardware respectively. Code verification normally entails detailed desk checking and software testing of the code, comparing it to the detailed design, documenting any discrep ancies and fixing any problems discovered. Other important activities include participating in code testing, audits, walkthroughs, and inspections; validating input data; preparing complexity report; conducting code analysis; and verifying code structure. Integration checking also sorted out by verification testing to address that is all component of the product or part is integrated properly and accurately. Validation and verification are present throughout all the phase of product life cycle and are composed of a wide variety of activities. The validation and verification activities are detection and correction of errors. In incremental assessment, which verification and validation activities provide at each phase of the process model. The information gives the progressive view of the productivity of the development process and quality of the product. 4.3.2 In a project life cycle verification and validation can arise in different stages. Those are mentioned below Requirements Interface requirements Developmental plans Configuration Management Plan Quality Assurance Plans Studies and Analyses 4.3.3 Checking Procedure of verification and validation Checked all the item that may need for the project development Requirement are checked through validation Test all the module for integrating correctly Design of the development mu
