The relative valuation model Essay Example
The relative valuation model Essay The purpose of this report is to undertake a firm valuation for Woolworths, using discounted cash flow model and the relative valuation model. This report provides information obtained through a conduct of Free Cash Flow to Firm Discount Valuation Model for Woolworths Limited (WOW), estimating the firmââ¬â¢s current share value. The report will then identify 3 key drivers of the firmââ¬â¢s value in this model; tests are performed in the report to identify the sensitivity of share value in the model to changes in specific variables. In the second section of this report, companies, with similar beta and Earnings per Share Growth as Woolworthsââ¬â¢, are analysed and compared, using Relative Valuation as another valuation method to estimate the WOWââ¬â¢s current value. Finally, this report will conduct a regression analysis to justify the result achieved in the Relative Valuation. About Woolworths Woolworths Limited is the largest food retailer in Australia with principal operations in supermarkets within Australia and in New Zealand. WOW and its main rival, COLES Supermarket, take up around 79% of the total grocery market. WOW also has other operations, which include liquor, petrol, general merchandise and consumer electronics. Woolworths has a market capitalisation of $29,927 million, its shares are currently trading at $24. 63 per share. (Market Cap and share price are acquired from FinAnalysis on 16 September 2011) Discounted Cash Flow Valuation Model (DCF) Discounted Cash Flow Valuation Model is used to evaluate the potential for investment by discounting back the firmââ¬â¢s future free cash flows. The DCF model used in this report is Free Cash Flow to Equity Valuation Model (FCFE).

The Australia 3-Year Government Bond yield on 16 September 2011 is used as a proxy for the risk free rate for this valuation. Firstly, Australia has SP highest credit rating of AAA, also a Fitch credit rating of AA+. These ratings denote expectations of Australia having very low to lowest default risk, very strong to exceptionally strong capacity for payment of financial commitments, where this capacity is not significantly to highly unlikely vulnerable to foreseeable events. Secondly, using Australian-dollar-denoted rate is an easier approach than using USD-denoted rate, where assumptions, for such as exchange rates, may deviate the valuation result from the true value. Thus, we believe that this is a comparable figure to represent the return demanded from a theoretically absolute risk-free investment over this valuation period. Levered Beta: 0. 71 throughout the 3-year high growth period. This is found on FinAnalysis on 16 September 2011. It was calculated by adjusting the industryââ¬â¢s beta based on WOWââ¬â¢s financial leverage. For stable growth period, ? =0. 8 is chosen, as WOWââ¬â¢s beta will approach to one when the firm is approaching to stable stage, which acknowledges the increased stability of WOW by the end of the high growth period. Price sensitivity to change in stable growth rate, 1st key driver of the firm value: One of the key drivers of the firm value is the assumption for the stable growth rate. In our initial valuation, we assume that the firmââ¬â¢s stable growth rate will be approaching to Australian GDP growth rate as the firm achieves stability. As presented, the estimated share value of WOW will increase as the stable growth rate increases. Price sensitivity to change in cost of equity during stable growth stage, 2nd key driver of the firm value: Another key driver of the value in the process of valuation is the cost of equity during stable growth stage. We initially assumed that the cost of equity will be 7. 64% as the beta of the firm will move towards one when the firm approaches stability. The estimated share price of the firm will decrease as the cost of equity during stable growth increases. Price sensitivity to change in length of high growth, 3rd key driver of the firm value: In the last scenario, the assumption of length of high growth period has changed from the initial 3 years to 5 years. This could happen due to the recent financial breakdown, which would significantly slow down the growth of the firm. Should 5-year high growth be used, Australian 5-Year Government Bond rate of 3. 81% is chosen as the risk free rate for the model, as a result of which, the Cost of Equity during high growth and stable growth stages will change as presented below. Other factors stay constant, the estimated share price of WOW will be $26. 80, under which circumstances, the firm is undervalued given the current share price is $24. 63 on 16 September 2011. PS ratio is believed to be uniformly measured as all financial figures for the comparable firms are obtained from the current financial year at FinAnalysis. As these comparable firms are from different markets that have different accounting rules, Price to Sales (PS) ratio is chosen as the multiple to evaluate these comparable firms. Besides that, a similar financial leverage across these comparable firms gives us more of the reason to use PS ratio as the multiple.

Socio-Economic Status of Slum Dwellers
Socio-Economic Status of Slum Dwellers Free Online Research Papers The study region is municipal area situated in dist. Pratapgarh, which sites in Gangetic plain in UP. It spreads over 12 km2 with total population of 71999 persons. In the age of urbanization in developing countries like India, the slums are like white spot on the body which is caused by uneven development. To sort out the urban problems, socio-economic study of the city is necessary and if we want to have clean cities in near future, the studies of slums are not only important but demand of time also. Therefore a sample area has been randomly taken for the socio-economic study. The parameters for demarcation slums are water supply condition, sanitation and road, employment, housing condition, sufficient living area. To sum up, the study reveals that a particular caste resides in a particular slum and these castes are related to either Pal or Harijan and Muslims. The slums lack with water, sanitation, road facility and it also denotes that the slum dwellers are unaware of programs launched by the Government. Pratapgarh District, one of the oldest Districts of UP, which came into existence in the year 1858, is situated in eastern part of UP. According to JNUââ¬â¢s development list based on socio-economic-agricultural, Pratapgarh stands in last category. So it is an undeveloped district. Pratapgarh district famous for its Aonla and people gives alias ââ¬Å"AONLA NAGRIâ⬠. The district, which forms from a part of Faizabad division, is named after it headquarter town Bela Pratapgarh commonly known as Pratapgarh. When district was constituted in 1858 itââ¬â¢s headquarter established at Bela which come to know as Bela Pratapgarh. The name Bela presumably being derived from the temple of ââ¬Å"Bela Bhawaniâ⬠, sites on the bank of river SAI. The study region districts headquarter; Bela Pratapgarh is situated at Allahabad-Faizabad national highway no. 96, at a distance of 39 km from Sultanpur and 60 km from Allahabad. Bela Pratapgarh city is a secondary town and spreads over 12 km2 with total population of 71999 persons (as per 2001 census). It is municipal area, which is divided in 25 wards so far. In total population of Bela Pratapgarh, percentage of OBC population is 31.58% and SC is 7.97%. The percentage of male and female population is 52.67% and 47.32%. The SEX ratio of Bela Pratapgarh is 898 which are quite lower than the district ratio (1004) and literacy rate is 71.039% which is higher than the district literacy ratio (58.67 percent). In Bela Pratapgarh, male literacy rate 77.03 percent followed by female 64.36 percent and district male literacy rate 74.61 percent followed by female literacy rate 42.63 percent. The Study Area: Study area of slums spread in all over the city in small patches. In 1997 District Urban Development Agency (DUDA) was stabilized and DUDA has declared 3 slum areas, these registered slums are Patkohli, Padawa and Karanpur. But there are some unregistered slum areas like Azadnagar, Khuskhuswapur, Pitai-ka-purwa, Bholiapur etc. Among these slum areas Patkoli ward is largest slum area with the 160 households. In Patkoli ward slum area is found in 3 patches- Ziriyamau, Patkoli and Bela Ghat; Pitai-ka-purwa with 2 patches- pitai-ka-purwa and nai-basti. Other slum areas have 30 to 60 households. Ward-name Basti name No of households Patkoli ziriyamau, patkoli, bela gaht 160 Aspatal ward Azadnagar 60 Bali Pur Khuskhuswapur 35 Pitai ka Purwa Nai basit, pure pitai 60 Padawa harizen basti 30 Karanpur Karanpur 35 Bholiapur Bholiapur 25 Objective of the Study: Every citizen has the right to live in a good living condition with employment, safety and other facilities. If any area left undeveloped, creates crisis in the mode of crime, unsocial activities, uneducated and unaware persons, low-level living condition, inadequate housing condition, unmoral citizens and unhealthy children with the unhealthy future of city and country. Now governments aware of the slum Basties of cities and launched many programmes to improve the condition of slum dwellers and his proficiency. But the game does not over, commonly seen that unregistered slums site over Urban Fringe area or at inner border of city, because of special spatial condition policies never imposed its effect in full fledged from. In city area, which is defined by the municipality area, plans take its own time to produce its impacts. Since, slums are present before the executions of development plans; therefore many problems stand in front of city and the citizens in form of crime, violence, poverty etc. These causes also exist in the study area. The objective behind the study aimed at to evaluate the socio-economic condition and to access the impact of government programmes upon slum dwellers of Pratapgarh City (Bela). Methodology: Every city has two types of slum areas i.e. registered and unregistered. The parameters for demarcating the slum are water supply condition, sanitation and road, housing condition. After that, to study the socio-economic status, a random sampling method has been adopted. For the survey and sample collection, a questionnaire has been prepared and door to door survey has been done. Because, Patakoli ward has large number of households, so, in this area 20 households were randomly selected for the study and in other areas 8 households have randomly taken. To evaluate the condition of dwellers, center tendency method is used. Social Status: In Bela Pratapgarh, slum dwellers are Hindus (64.44 percent) and Muslims (35.64 percent). In the total population of slum dwellers OBC with 57.14 percent, are in majority followed by SC with 33.65 percent and General with 9.2 percent. Religion CATEGORY PERCENTAGE HINDU GENERAL 2.955 OBC 47.783 SC 49.261 MUSLIM GENERAL 20.595 OBC 74.107 SC 5.357 Among Hindus, SC population is 49.261 percent and followed by OBC with 47.783 percent and General with 2.955 percent. In Muslims, OBC population is in majority with 74.107 percent followed by General 20.595 percent and SC with 5.357 percent. In slum areas sex ratio is 944 is greater than the Bela Pratapgarh sex ratio (898) and State sex ratio (898) but lower than district sex ratio (1004). In slum areas Hindus sex ratio (1071) is higher than Muslim sex ratio (778). Literacy: The overall literacy rate in slum areas is 56 percent with male and female literacy 65 percent and 46 percent against 71.039 percent in Bela Pratapgarh with male and female literacy 77.03 percent and 64.36 percent. Literacy rate of slum areas, near to district rate (58.67 percent) and UP state rate (57.36 percent) but it lower than the National rate (64.8 percent). The male literacy rate of slum areas 65 percent is quite lower to district rate (74.61 percent), national rate (75.8 percent) and state rate (70.23 percent) but female literacy rate 46 percent is near to district rate (42.63 percent), state rate (42.98 percent) and lowers than the national ratio (53.7 percent). In slum areas Primary educated persons are in majority with 60.71 percent followed by Madhyamic (28.27 percent), Inter (5.089 percent), Graduate (2.68 percent) and Post-Graduate (1.071 percent). The vocational trained persons are 1.09 percent. Income: Total working people percentage of slum dwellers is near about 24.14 percent. Among these persons, 60 percent people do not know the nature of dayââ¬â¢s work. The average of working day in a month stands between 16 to 20 days. Over all average income of slum dwellers is quite lower with 13.03 Rs a day/person against the urban poverty line, which is near about 17 Rs. Average income of a working people 55.98 Rs for doing work 7 hour and 36 min in a day, which is quite lower than the UP Government regulation. Housing condition: In slum areas housing conditions are found in a very poor position. In sample area 46.34 percent of Kchcha houses made by mud, plastic and bamboo, 21.95 percent of Pakkaa houses made by bricks and 31.71 percent houses made by mud and bricks which have greater part Kachcha and smaller part Pakka. So, 78 percent of households face problem of housing. Sanitation, Water, Road and Health: In slum area sanitation and road facility are totally unavailable, for example except karanpur, ziriyamau, ptakholi, bela ghat, padava have Kaccha road and azad nagar, khuskuswapur, nai basati and pitai ka purwa have Kharanja road. In these areas drinking water facilities totally unavailable, except Azadnagar, in other ward water source is well or government hand pump, at per 25 households. Also in Azadnagar drinking water facilities totally unavailable and dwellers get drinking water from hand-pumps of rich neighbors. In other areas, if there is water supply, its condition is very poor. Generally water supply pipes are sunk in drain water. Hence, the water can not be used being coal black. In slum area latrine facilities are in poor condition, only 20% households have own latrines and other 80% uses the open lands. The wastages of households dump by householder near the open land or the path. As far as, the total environment of slums does not good, in all these areas children are suffering from viral infections, boils, fever etc for ever. Social Activities: -In crime, violence and immorality slum areas are leading portion of the city. In study area violence seems as quarrel, fight or abuse in home with wife, children, parents etc. or with the neighbors. The day life of the dwellers start and end with the quarrel and it happens because of drinking liquor. Immorality can be seen in the form of gambling. A sentence told by an old man to me in zriyamau about the gambling, pinched me a lot. He told, ââ¬Å"He bhaiya agar in nanha-nanha larikan ka juaa chudawai detya tau enkar kalyan hoi jaatai.â⬠(If you can escape younger Boys from gambling, then they would lead a good life). In these areas some families are vagabonds. Police keeps an eye over them, arrest and warn. Because most of them many times involved in unsocial and immoral activities like snatching, thieving, gambling etc. Government Plans and Awareness: District Urban Development Agency is the coordinating agency at district level for formulating different developmental schemes in urban areas. The following schemes/programmes are being implemented under the supervision of DUDA. Swarna Jayanti Sahari Rojgar Yojana, which is currently in operation with effect from 1.12.97, is a substitution of the earlier programmes like Urban Basic Services for the Poor (UBSP), Prime Minister Integrated Urban Poverty Eradication Yojana (NRY), Environmental Improvement of Urban Slums (EIUs). Under the scheme SJSRY, the following programmes are being implemented in all the ULBs of this district. Community structure (Information Education and Communication (IEC) Component. Urban Self Employment Programme (USEP) (subsidy) Development of Women and Children in Urban Areas (DWCUA) Thrift and Credit Society Urban Wage Employment Programme (UWEP) U.S.E.P (Skill up gradation Training) Administration and Office expenses (A O.E.) About these programmes and DUDA slum dwellers unaware and in sample area only one person know about DUDA and its U.S.E.P. programme. It shows the lack of publicity of programmes and unawareness of slum dwellers. Some advantages they gain from common programmes like Antyodaya yojana, Mid-day-Meal programme and Scholar-Ship programmes. Conclusion: To conclude; we can say that a big number of people, known as slum dweller, are forced to live below poverty line. The main reason of their poverty is illiteracy and lack of will power to improve his condition. They always look for the government helps; debt, relief etc. and wait for them, this type of mentality and government plans make them paralyzed instead of self reliance. They lack behind good education, health, sanitation and economy. There are Governments plans to improve their poor condition. But these programmes are executed half heartedly. There is need to focus their problems and a strong heart and mind to execute these programmes. If it happens so, the day will come with hope for them and for the people who are affected by these slum dwellers.

Paradigm Paper Essay Example | Topics and Well Written Essays - 1250 words - 1
Paradigm Paper - Essay Example Since gender is culturally determined, it is complex in nature. In the long run gender identity focuses on the various customs within an individual about their socio-cultural life. This is different from other the observation in other animal kingdoms which is specific to the task of reproduction. Sexuality, viewed in this regard in the human kingdom would just be but the tip of an iceberg. Why is this so? This is because human beings have in the recent past lived in such an advanced era that they have changed the original mode of reproduction. In the modern times, reproduction can be fully made a success even in a modern laboratory. This makes it also vary dynamically from one region, society, country or even continent, to the next. There are several gender issues that so much affect the societies globally. Key of this is provision of opportunities. It is evident that most societies we live in provide opportunities that are not equal. For example, the economic principle of division o f labor helps promote biases related to gender. Class Also in regards to sociological question, class is defined as an organization of a given social grouping; which are characterized by similar rights, perceptions if not qualities, and duties. These are most often founded innately on one side and through socialization on the other side. As an end, class is deemed with the task of founding a culture since there it forebears a routine within the organization in question. It is therefore no surprise that the local societies as well as the world over are usually classified. This alone describes the functionality definition of ââ¬Å"class.â⬠Age This refers to the cognition about ones introvert experiences of their age and the developmental stages they are undergoing. It is concerned with identity and can be able to inform any individual where they belong and where they do not belong. For example, the youths know their rightful position and are often perceived by the aged as inexp erienced. On the other hand, the old also presume the role of overseer in any given society, but often in the same societies, the youths consider them with distasteful reactions. This identity does belong to and can be based subjectively to the experiences a person undergoes when aging. Some people will mature in age but the same people may fail to attest to this development. Some may also be young but attest to aging, which for a fact is not the case. In this regard this discipline becomes fundamental to study because it displays a myriad of platforms upon which an individual life may be considered. The other significance is that every individual considers their identities with this importance because their development is so fundamental to them. The aging process can also be used to explain various human psychological processes. A good example is in the learning process. During learning each individual undergoes a change, for example, in this assignment of paradigm paper, I will be able to evaluate myself on my positive progress during this pre-test period and after I shall have undergone a detailed learning process. Belief System A belief system is defines by a perceived way of thought, which most often is termed as a school of thought. It is knowledge that has been conceptualized and standardized in a unique way to form living principles of an

Dog Training Essay Example | Topics and Well Written Essays - 2000 words
Dog Training - Essay Example Other dogs elsewhere in the world were lovingly inherited by their own masters. Even Oprah Winfrey had written a will endowing $30 million to her 5 dog pets ensuring that they will be pampered throughout their lives even if she has already passed away, Woman's Day reported (Woman's Day, Sept. 10, 2007). Ordinary people care for their dogs as if they're caring for their own children, sleeping, eating and even traveling with them. This hardly can be considered a phenomenon because dogs among all creatures in the universe evince qualities and traits that are even difficult to find in humans and these are purity of heart, unconditional love and devotion, the absence of malice and hidden motives or sincerity, unfathomed fidelity and loyalty and the adherence to his master in all adversity and through all vicissitudes. When one loves his or her dog 50% in intensity, his or her dog returns it 100%. The dog's love is consistent and unfailing. While spouses show affection only in the early years of the marriage, dogs show affection day in and day out, year in and year out. The dog's warmth, devotion and obedience know no barrier nor limits. We often hear of stories of dogs pining for their master's presence even after the latter's death. In Edinburgh, Scotland a Skye Terrier named Greyfriars Bobby spent 14 years guarding his master's grave until his own demise. His saga was immortalised in the Disney movies Greyfriars Bobby (1961) and The Adventures of Greyfriars Bobby (2006) (Atkins 2005, pp.52-256). War stories such as those from World War I are even more replete with stories of dogs refusing to leave their masters' corpses even if they were already in a state of decomposition. Then there was the story of Heidi, the Russell Terrier who sought out her Scottish master, Graham Snell who fell in a cliff and died. Finding him, she traversed down the 500 foot ravine and stayed with Snell until they were reached by a rescue team (dogsinthenews.com). All of these stories are endless, all earning for the dog the sobriquet, 'man's best friend'. Dogs' Natural Instincts Researchers have always claimed that dogs trace their lineage from gray wolves (canis lupus) some tens of thousands of years ago. As a priori evidence, many have adduced as evidence the similarity of structures and the period of gestation between the two species (Richardson 1857, p,18). They were ostensibly domesticated when wolves' pups were taken 3 and bred and tamed by early men and successfully socialized. By the process of intentional cross-breeding, the tamed domestic dog (canis lupus familiaris) emerged (Scott & Fuller 1974, p.140). Since then they had been

Gas turbine engine
Gas turbine engine TURBINE BLADE COOLING ABSTRACT INTRODUCTION It is well known from the thermodynamic analysis through literature survey that the performance of a gas turbine engine is strongly influenced by the temperature at the inlet to the turbine. Figure 1 illustrates the relation between the specific power output and turbine rotor inlet temperature. There is thus a growing tendency to use higher turbine inlet temperatures, implying increasing heat loads to the engine components. Engine manufacturers have recognised this for some time and have been continuously increasing turbine inlet temperature, especially during the last three decades. The blades are cooled by extracting air from the compressor stages. Modern gas turbine engines are designed to operate at inlet temperatures of 1800-2000K, which are far beyond the allowable metal temperatures. Thus, to maintain acceptable life and safety standards, the structural elements needs to be protected against the severe thermal environment. This calls for the design of an efficient cooling system for these elements. Rotor blade of high pressure gas turbine is such a critical element and hence the blade metal temperature should not be allowed to exceed beyond a value at which the life or safety standards cant be met. It is required to cool the blade in such a way that the amount of heat transferred from the externally flowing hot gas to the blade should be removed by an appropriate cooling design to limit the very high temperature. STRESSES IN THE BLADE Rotor blades of gas turbine are subjected to very high rotational speeds of the order of several thousand rpm and also are exposed to a variable thermal environment. Hence these blades are subjected to different types of stresses of different magnitudes and directions. As it is known, that the strength is a function of life and working temperature the net stress at any section of the blade should not exceed the maximum allowable value. The control on the blade metal temperature is the only way to sustain the stresses for the designed life of the blade for a specific operating condition and life requirement. Therefore to know about the cooling requirement, stresses should be predicted correctly on the blades at different sections. There are mainly four types of stresses with that rotor blades are being subjected; Centrifugal tensile stress Gas bending stress and Centrifugal bending stress Thermal stress 1.1. Centrifugal tensile stress Centrifugal stress in the rotor blade is due to the rotation of the blade. It is tensile in nature. This is the largest in magnitude but not necessarily the most important because it is almost a steady stress. When the rotational speed of the blade is specified, the allowable centrifugal tensile stress places a limit on the annulus area but does not affect the choice of blade chord. This stress is the basic cause of the blade failure due to the creep. 1.2. Centrifugal bending stress If the blade design is such that the centroids of all the blade cross-sections at different radii, taken perpendicular to the radial direction, do not lie in the same radial plane, centrifugal stresses arising in the blade will try to bend the blade. This type of stress arising due to the different directions of the centrifugal stresses in different blade sections is called as centrifugal bending stress. It will produce compressive stress in one side of the blade whereas tensile stress in the opposite side. Any torsional stress arising from these centrifugal stresses is small enough to be neglected. Thus this stress is very sensitive to manufacturing errors. 1.3. Gas bending stress The force arising from the change in angular momentum of the gas in the tangential direction, which produces the useful torque, also tries to bend the blade about the axis of rotation of the blades. The stress arising due to this bending force is called as gas bending stress. There may be change of momentum in the axial direction and in reaction turbines there will certainly be a pressure force in the axial direction. All these two will produce a bending moment in the blade about the tangential direction. The gas bending stress will be tensile in the leading and trailing edges and compressive in the back of the blade and with tapered twisted blades either the leading or trailing edge suffers with the maximum value of this stress. This is a fluctuating stress and its value becomes maximum when the rotor blade passes through the leading edge of the stator. 1.4. Gas bending stress Turbine blade is subjected to three-dimensional temperature gradients, along the blade height, along the blade profile and along the thickness of the blade. Due to these temperature gradients the blade fibres tend to deform unequally. This unequal deformation causes mainly two types of stresses to set up in the blade, compressive and tensile. As the blade considered is un-cooled therefore the contribution of the stress due to the temperature gradient along the thickness of the blade in net stress is not appreciable and can be neglected. Usually with the cooled blade this source of stress is main among all the sources of thermal stress. Again the thermal stress due to the temperature gradient along the blade height would not come in picture because the blade is free to expand along the height. Only the stress due to temperature gradient along the chord of the blade will contribute in net blade stress but its magnitude would not be much because the temperature gradient along the chord is not so high. BLADE MATERIAL AND STRENGTH Gas turbine blades are exposed to a very severe thermal atmosphere. The temperature is so high that it is fairly much more than the melting points of the common high-strength materials. Besides high temperature the requirement of durability is also another factor, which makes common materials unsuitable for use. Only super alloys may be suitable for this purpose. But the current trend of continuously increasing the turbine entry temperature attracted the concentration of the designers not only towards the new materials with well-improved mechanical and thermal properties but also to restrict the temperature of the blade material by its proper cooling. So, the material should have sufficient strength to face the operating situations. 1.5. Strength of blade material In ordinary temperature conditions the strength of the material under constant loads is estimated by tensile strength or yield strength. At high temperatures under action of constant loads in ordinary structural materials there appears the phenomenon of creep. It occurs as a result of prolonged exposure of materials to high stresses at high temperatures. This is particularly a acute problem on highly stressed rotating turbine blades and it occurs in the form of slowly and continuously developing plastic deformation. And excess of this plastic deformation causes the failure of the component. It is observed that at constant stress the higher the temperature the more quickly proceeds the process of creep i.e. the lesser the life of the component. It means that at a particular stress lesser will be the temperature higher will be the life of component. Therefore life of the component is a function of working temperature and stress. Hence to maintain the life of the component at a desire v alue it is required to lower the temperature of the component. Gas turbines operate in conditions of high temperatures and therefore in highly stressed components like rotor blades there appears the phenomenon of creep. Therefore for these cases where creep is the main criterion behind component failure the ultimate tensile stress is defined as the stress at which the component fails at a certain working temperature after the expiry of a certain period of time. It means that the strength of the material subjected at high temperatures is a function of this temperature and its operational life. PAST COOLING The technology of turbine cooling was recognised by some almost from the inception of the first turbojet engine. Cooling studies were first performed in the 1940 and many investigations were carried on in the 1950s. Around 1960, turbine cooling was first used in a commercial aircraft engine. Since that time, there has been a very rapid rise in turbine inlet temperature that has placed an even greater emphasis on turbine cooling. A continuous improvement in high-temperature materials has also helped to increase the turbine inlet temperature. The cooling technique used during 1960s was single internal passage convection cooling. The air used for cooling was injected through the root of the blade and to the internal aerofoil.

The Continuing Importance of Affirmative Action Essay -- Argumentative
The Continuing Importance of Affirmative Action à Affirmative action is about to take quite a beating. Prominent Republicans from Phil Gramm to Pete Wilson to Bob Dole all plan on making the attack on affirmative action a central plank of their campaign rhetoric. The Clinton administration, perhaps trying to stem the attack before it begins, recently announced that it would reevaluate the merit of all affirmative action programs. And many of those to the left of Clinton oppose affirmative action--albeit probably for different reasons than those to his right. Considering the overwhelming opposition to affirmative action, it seems improbable that affirmative action would have much to recommend it. Yet this contention deserves examination. There are a large number of factors contributing to a given policy's favorability; it seems unlikely that all aspects of affirmative action, from morality to reality to the gray in between, count as strikes against it. Concerns over fairness to white males seem to be at the root of most opposition to affirmative action. This argument is difficult to counter; it seems clear that affirmative action does amount, strictly speaking, to reverse discrimination. For some, this fact alone is enough reason to ring the policy death knell. Yet this conclusion seems to me hasty. If affirmative action hurts white males only a little, yet helps minorities and women significantly, then we might well decide to keep affirmative action around, despite its unfairness. Private universities commonly employ policies of preference which are sometimes euphemistically termed "development policies." Development means that there is a concerted effort on the part of admissions officers to admit students who come fro... ...(If you are unconvinced of this point, do a bit more reading and thinking.) More than lowering the hiring and admissions standard by which minorities and women are measured, affirmative action works to counteract pervasive racism. If an employer harbors racist, heterocentrist, or sexist views, then being forced to take a second look at minorities and women may counteract that prejudice. Affirmative action, then, may have less to do with lowering the standard by which minorities and women are measured, and more to do with equalizing opportunities given. That sounds to me like sound policy even Newt would find difficult to oppose--policies designed to ensure equality of opportunity. For as long as it has been policy, affirmative action has been implemented with an eye towards equalizing opportunity. A more admirable, mainstream ideal is difficult for me to envision.

Baptist Confessions
This essay will consider the English Baptist-Separatist Confession of 1609 and the Mennonite-Dordrecht Confession of 1633. (M) and (B) are used to distinguish the two documents. These two confessions, or statements of belief, are separated by only 24 years in time, and a relatively short distance geographically, one in Holland and one in England, yet there are a number of differences. It was John Smyth, a former Anglican minister, who drew up the Separatist confession. He later sought to align his church more with the Mennonites and after his death many of his congregation did become Mennonites.Despite this he is considered to be a founding father of the Baptist denomination. During the reign of Elizabeth I death was the penalty in England for those holding Anabaptist beliefs according to the Reformed Reader web site. The other document tells us in its heading that it came out of the Dutch Mennonite conference held at Dordrecht . The Mennonites were Anabaptist followers of Menno Simo ns, a Dutch religious reformer and former Catholic priest who had died some 72 years earlier in 1561. Between 1530 and the1590ââ¬â¢s some 2,000 believers died for their faith in Holland according to the Continental European Protestantism web page.They were officially tolerated from then on, but many refused to fight in wars on Hollandââ¬â¢s part, and preferred to flee elsewhere, some to Poland and the Ukraine and other to America. So both these confessions came at a time when official persecution was lessening. First of all one is much briefer than the other. Although it has some 20 sections the Separatist confession has only short discourses under each heading and runs to less than 2 pages of foolscap, whereas the Mennonite document, although it has only 19 sections is very much longer and more detailed.It is one of many Mennonite statements of faith. A much shorter version can be found on modern day Mennonite web sites. The first 6 of its articles are concerned with things g enerally believed. Then come articles concerned with the life of the church and includes the sacraments of baptism and communion. Articles 13 (M) onwards are concerned more with legal matters such as the relationship between believers and the secular authorities. The final section consists of a declaration of 1659 made by London based Anabaptists and is a refutation of accusations that had been made against them.Rather than a statement of belief it emphasises what they donââ¬â¢t believe e. g. that though they do not themselves practise infant baptism they believe that others should be allowed to follow their own consciences as they would wish to. They state very strongly that they are opposed to the Quakers, but at the same time wish to be tolerant and allow them to practice freely as they believe. They do come out strongly against ââ¬Ëpoperyââ¬â¢, whom they blame for many deaths. Although concerned with freedom of conscience they are anxious to let it be known that they wi ll not support miscarriages of justice.This is in response to the fact that at the time of writing it Mennonites could be imprisoned simply for belonging to the group according to Cornelius Dyck in ââ¬ËAn Introduction to Mennonite Historyââ¬â¢, pages 133 and 134. The Mennonites, although sticking to what they believe, are anxious to get on with rest of society. They have a section (13) (M) stating that God has allowed secular people to be in authority. In practice this means that though Mennonites will not go to war they will work under secular authorities in such areas as disaster relief and issues of social justice.Baptists too are concerned with such matters as in such organisations as the Baptist Missionary Society. The English Baptist statement spends a larger proportion of its text upon matters of faith and these are given priority. Only three articles, numbers 16-18, (B) are concerned with church business, i. e. who may dispense the word and the sacraments, how to deal with persistent sinners and how to interact with them in civil matters. The Mennonites also make statements of faith of course, but these are intermixed to some extent with such matters as the election of officers and dealing with sinners.On the latter subject the Mennonites are quite strict , referring to the separation from and the total shunning of reprobates, though they do put this in a positive light as being a way of making the person make amends and not in order to cause their destruction ( articles 16 and17 (M)). The Baptists are more pragmatic in their approach. They describe in article 17 (B) how to deal with those who persevere in their sins, but go on to say in the next article that such people are not to be avoided in worldly business.Regarding church practices an obvious difference is the inclusion of foot washing by the Mennonites, article 11,(M) which they felt was commanded by Christ in John 13 v 1- 15. They are one of several Christian groups throughout history wh o have practised this symbolic act, although it seems unlikely that it was included among the practices of the early church. The Baptists make no mention of marriage, despite the fact that many branches of the church consider it to be a sacrament. The Mennonites on the other hand state that it is God ordained and that St Paul allowed it within the church.(Article 12 (M)) They do state though that it should be between Christians who share common doctrine. In practice this means of course fellow Mennonites. Regarding Baptism the English Baptists make it very clear that it cannot be given to infants ( Article 14 (B)). The Mennonites in their confession ( Article 7 (M)) do not directly mention infants, but make it clear that it is for those who understand what they are doing and confess to faith, whereas this Baptist confession merely says that it is an external sign of the remission of sins, but makes no mention of public confession of faith.The Baptist confession describes its ministe rs as bishops and also mentions deacons and widows. (Article 16 (B)) It describes the church simply as ââ¬Ëa company of the faithfulââ¬â¢,( Article 12(B)) and gives the whole body authority to make decisions. ( article 13 (B)). The Mennonites refer to the church in much more elaborate language as the bride of Christ and the inhabitation of God in the Spirit. The Mennonites refer to the church leaders in slightly different terms as teachers, deacons and deaconesses, though they do make it clear further on that the latter term refers to widows.They refer to Jesus as the Bishop ( Article 9 (M)) and it is men who will do the teaching. There are of course many areas in which the two documents are in agreement. E. g. both refer to God as a trinity and as creator and that good works come out of faith rather than the other way round. In Article 5 (B) the Separatist states that there is ââ¬Ëno original sinââ¬â¢ i. e. one is not a sinner by descent. This is in total contrast to Ar ticle 2 (M) of the Mennonite confession which states that because of the disobedience of Adam and Eve sin came into the world and has descended to all mankind, though both agree that man can be redeemed through Christ.The Mennonites are very concerned that faith is up to the individual, which explains their tolerance to the state and willingness to pay taxes etc. ( Article 13 (M)) Regarding communion, Menno left the Catholic church in part because of his lack of belief in the actual presence of Christ in the elements. The Mennonite document speaks rather of a holy supper,(Article 10 (M)), as commanded by Christ and in memory of what he had done.Smyth describes it on the other hand as ââ¬Ëan external sign of the communion of Christ and of the faithfulââ¬â¢ ââ¬â Article 15 (B) and makes no mention of it being either a command or a memorial. Mennonites do not take oaths and quote scripture to back this up. They ask that others will understand and just take them at their word. Another area mentioned by the Mennonites and not by the Baptists is what they refer to as revenge, but which perhaps their fellow countrymen saw as justified war fare. The Mennonite statement in article 14 (M) explains their scriptural reasoning for this stand.Baptists would agree with them, but for some reason it is not mentioned. Many of the differences in these two documents are simply due to the type of authorship ââ¬â one man as against a committee, the later being careful to check with each other before committing themselves to final wording, not omitting any point considered valid, hence the more complex language and greater length. Ye both groups would agree about many things ââ¬â the need for faith and understanding before baptism, the greatness of God and the unique nature of Christ and his redeeming action.Both share a belief in the resurrection and in life eternal, even though they express this in slightly different ways, the Mennonites backing up their statemen ts with scripture and the Baptists seemingly taking this as understood. These two groups came into being because of the Reformation and new ideas that were around at that time, especially with regard to the onus on an individual to come to faith, rather than being automatically part of the church, because he had been baptised as an infant, without either faith or understanding on his part.The biggest difference between the two seems to be with regard to manââ¬â¢s sinful nature and how he acquired it.. Baptists and Mennonites continue to worship and live according to their conscience. Not every Christian would agree with every word written in these confessions, but it is to be hoped, that like the writers and followers they would be tolerant in Christian love.

British Airways PR Plan
British Airways PR Plan Advertising We will write a custom report sample on British Airways PR Plan specifically for you for only $16.05 $11/page Learn More Executive Summary This paper is a PR plan for a leading aviation company, British Airways (BA). Traditionally, people have known BA as an experienced and reliable company, but recent industrial strikes have eroded this perception. This paper proposes that BA should reclaim its image as the most reliable and experienced company by focusing on improving the perceptions of its employees and customers about the company. Relative to this goal, this paper proposes several strategies including the adoption of an open communication policy, where the company should invite all stakeholders for an open interaction through social media and face-to-face interactions. The objective of this strategy is to improve the level of interaction between BA, its employees, and its customers. Through this interaction, BA should demonstrate that it genu inely cares about the welfare of its customers and employees by showing genuine interest in improving customer service and employee working conditions. Background A founding member of the One World Alliance, BA is the national carrier for United Kingdom. The UK government established BA in 1974, but in 1987, the same government privatized the company after nearly 13 years of state control.Advertising Looking for report on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Since then, British Airways has cut a niche in the aviation industry as being among the largest airline companies in the world. Indeed, only until 2008, British Airways held the reputation of being the largest airline company in the world, in terms of its fleet numbers. The companyââ¬â¢s main operational hub is at Heathrow airport, but its global presence spans across 150 destinations around the world. Underlying British Airwayââ¬â¢s success is an eroding public confidence about the airlineââ¬â¢s reliability as a customer-focused airline company. A series of industrial strikes that nearly grounded the companyââ¬â¢s operations in most of its key markets caused the eroded confidence. For example, throughout most parts of the years 2007, 2008, and 2009, British Airways suffered from a string of industrial actions by its employees. The employees protested poor working conditions and low pay. The industrial actions caused a series of flight delays and flight cancellations that inconvenienced most of BAââ¬â¢s customers. The disorder dented BAââ¬â¢s public image when stiff competition from rival global airline companies and local low-cost airlines undermined the BAââ¬â¢s market leadership. BAââ¬â¢s management was unable to contain most of these strikes, thereby further denting the airlineââ¬â¢s image as a reliable airline company. Since then, BAââ¬â¢s has had a difficult time trying to redeem its image as a reliable airline company in the eyes of the public. Situation Analysis This situational analysis follows four main aspects of BAââ¬â¢s operations: strengths, weaknesses, opportunities, and threats. They outline below:Advertising We will write a custom report sample on British Airways PR Plan specifically for you for only $16.05 $11/page Learn More Strengths Most of BAââ¬â¢s strengths stem from its past leadership in the airline industry. For example, BAââ¬â¢s vast global operations earned it the reputation of a respected global airline company with vast experience and operational control around the world. The companyââ¬â¢s expanding fleet of modern aircrafts and the success of some of the companyââ¬â¢s loyalty programs (such as the executive club) also comprise some of the companyââ¬â¢s key strengths Weaknesses Some airline customers regard some of BAââ¬â¢s flights as expensive because many low-cost airlines charge relatively lowe r prices for air travel. BA has found it difficult to compete with such low-cost airlines because it maintains several extensive global operations. The high costs of managing and running the extensive global operations have significantly increased the companyââ¬â¢s bottom-line costs. BAââ¬â¢s has also suffered negative publicity from poor services that have culminated through a rise in the number of lost luggage and cancelled flights. These factors have led to the companyââ¬â¢s declining profitability. Opportunities Since most of BAââ¬â¢s competition come from low-cost airlines, the biggest opportunity that exists for the company is starting a low-cost airline division for its international fleets. This way, the company would be able to charge low fares for a big part of its core customer base, which is increasingly seeing the rival low-cost airlines as a better alternative than BA.Advertising Looking for report on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More In addition, since most of BAââ¬â¢s operational costs trace to high fuel costs, the company may invest in the sourcing of alternative fuel to power its aircrafts. This initiative involves funding research and development initiatives that work to serve this purpose. Threats Like most airline companies around the world, BAââ¬â¢s greatest threat is increased competition. In addition, as mentioned in the above section of this report, high fuel costs also threaten the companyââ¬â¢s future sustainability as it erodes most of its profitability. BA has also lost most of its cabin crew through its extensive strikes and a crumbling corporate image. This issue has made it more difficult for the company to replace its lost cabin crew, as few potential employees are willing to work with the company. Message Statement The emerging themes in this PR plan include customer sensitivity, employee loyalty, and brand consistency. The main idea behind the proposed PR plan is to create a positive brand image by achieving customer and employee buy-in. In other words, the proposed PR plan singles out BAââ¬â¢s customers and employees as the main stakeholders that have the power to improve the companyââ¬â¢s public image. By achieving employee loyalty, the proposed PR plan aims to convince its customers that all is well with the company and the focus for the company now is the welfare of its customers and employees. This message statement especially relies on BAââ¬â¢s past image as the leading airline company in the world. The proposed PR plan aims to reaffirm the notion that BA is more experienced, caring, and capable of meeting customer and employees demands, compared to other upcoming companies. Communication Process The aim of this communication process is to improve the interaction between BA with its employees, its customers, the public, and the media to improve the companyââ¬â¢s image in the community. BAââ¬â¢s communication process should stem from a syste mââ¬â¢s perspective. The systems perspective will help the organization to communicate with the employees and customers by establishing a stable company image of reliability and community focus. The systems theory explains this model. Feedback will be an important part of the communication process because feedback may help BA to improve the effectiveness of its communication and PR plans. The communication process will be open to all stakeholders of the PR plan because the PR plan needs to be self-sustaining. Stated differently, by including the inputs of the companyââ¬â¢s main stakeholders (customers and employees), the PR plan will be able to evolve and meet the needs of the organization. Audiences BAââ¬â¢s employees and customers outline the focus of the companyââ¬â¢s PR plan. Employees are a critical audience for the company because their dissatisfaction with the company created the public image crisis that BA faces today. In addition, through employee strikes, BAâ⠬â¢s customers lost confidence in the company. The employees and the customers therefore outline the main target audiences for BA because both groups stand at different ends of the PR plan. A change of the employeesââ¬â¢ perceptions about BA is likely to rub off on the customers because the employees may offer better customer services if BAââ¬â¢s management pays close attention to their welfare. Through improved services, BAââ¬â¢s employees will attract more customers to the company. This situation is likely to improve the companyââ¬â¢s image, sales, and profitability in the end. Key Audience Messages The key audience message of this PR plan is to convince BAââ¬â¢s employees and customers that the company cares for their welfares. The PR plan should communicate to both groups of stakeholders that the company is genuinely interested in improving their welfare because it understands their importance in achieving corporate success. Through this commitment, BA should de monstrate that it genuinely values the employees and customers by improving its customer services and rewarding its employees for positive work. These initiatives should culminate in a ââ¬Å"BA open dayâ⬠program where the managers, employees, and customers meet and share insights regarding the companyââ¬â¢s operations. This way, the company will make the employees and customers believe that it is genuinely interested in their concerns by opening its communication channels to both groups of stakeholders. Implementation The best way to reach the target audiences for this PR plan is through social media and face-to-face communication. Demographic assessments of BAââ¬â¢s customers show that the customers frequently use social media. The company can therefore effectively communicate with its customers this way. Moreover, social media provides a cheap alternative for BA to interact with the customers. However, employees should get a special attention from the top-level manage ment, through face-to-face interaction, because the management should demonstrate that it is genuinely interested in their welfare. Therefore, BAââ¬â¢s managers should steer the PR implementation process and not fully delegate the responsibility to a PR firm. Budget The budget for the public relations plan focuses on research, information gathering, monitoring and evaluation, and strategic integrated communication. The following spreadsheet outlines the budget estimates for these activities. Activity Qty/Year Hours Expenses Total Research 0 50 $1,750 $87,500 Information gathering 0 40 $1,000 $40,000 Monitoring and evaluation 0 60 $2,000 $120,000 Strategic integrated communication 0 40 $2,750 $110,000 Base Program Budget $357,500 Monitoring and Evaluation Measuring Public Opinion Measuring public opinion is a reliable way of understanding the effectiveness of the PR plan. BA should measure the public opinion before and after the execution of the PR plan, to unde rstand the impact of the PR strategy on the companyââ¬â¢s brand. The public opinion should be measured using customer and employee surveys. Assessing the responses in the customer surveys may show if BA has achieved the objectives of the PR plan, or not. Social media evaluation Since social media forms a key part of this PR strategy, social media evaluation may provide a reliable indicator for monitoring and evaluating the impact of the PR plan. The key indicator of this assessment is the quality and level of interaction between the customers and the company (not the number of followers). If there is a high level of interaction between the company and its employees, or customers, BA should expect the development of a positive brand image. However, if the levels of interaction between the company and the employees, or customers, fail to increase, then BA should assume that the PR plan has failed to achieve its objectives.

How to Prepare a Sodium Hydroxide or NaOH Solution
How to Prepare a Sodium Hydroxide or NaOH Solution Sodium hydroxide is a common and useful strong base. Special care is required to prepare a solution of sodium hydroxide or NaOH in water because considerable heat is liberated by the exothermic reaction. The solution may splatter or boil. Here is how to make a sodium hydroxide solution safely, along with recipes for several common concentrations of NaOH solution. Amount of NaOH to Make Sodium Hydroxide Solution Prepare solutions of sodium hydroxide using this handy reference table which lists the amount of solute (solid NaOH) that is used to make 1 L of base solution. Follow these lab safety guidelines: Dont touch sodium hydroxide! It is caustic and could cause chemical burns. If you do get NaOH on your skin, immediately rinse it with a large volume of water. Another option is to neutralize any base on the skin with a weak acid, such as vinegar, and then rinse with water.Stir the sodium hydroxide, a little at a time, into a large volume of water and then dilute the solution to make one liter. Add sodium hydroxide to waterdo not add water to solid sodium hydroxide.Be sure to use borosilicate glass (e.g., Pyrex) and consider immersing the container in a bucket of ice to keep the heat down.Ã Inspect the glassware prior to use to make sure it is free from any cracks, scratches or chips that would indicate a weakness in the glass. If you use a different type of glass or weak glass, theres a chance the temperature change could cause it to shatter.Wear safety goggles and gloves since there is a chance the sodium hydroxide solution could splash up or the glassware could break. Concentrate d solution of sodium hydroxide are corrosive and should be handled with care. Recipes for Common NaOH Solutions To prepare these recipes, start with 1 liter of water and slowly stir in the solid NaOH. A magnetic stir bar is helpful if you have one.

Electromagnetic induction Assignment Example | Topics and Well Written Essays - 2250 words
Electromagnetic induction - Assignment Example This paper illustrates that in magnetic induction, the induced elctromotive force or emf in a closed circuit would be equivalent to the time rate of the magnetic flux passing through the circuit. Electromotive force, emf is the energy gained per unit charge that passes through an electric conductor such as a generator. Emf in any circuit is measured in Volts, and a source to give the emf is applied to power up the circuit. On the other hand, in magnetic induction, the magnetic flux will refer to the amount of magnetism or the strength of a specific magnetic field.à Two laws are important in understanding and explaining electromagnetic induction. These are the Faradayââ¬â¢s law and Lenzââ¬â¢s law. Faradââ¬â¢s law states that any charge passing through a magnetic field of a coil of wire will produce a voltage (emf) to be induced in the conductor. A voltage will always be produced despite the charge of the conductor or the magnetic field. The figure below summarizes Faradyâ â¬â¢a Law by explaining how voltage is generated between a conductor and a magnetic field in what is termed as magnetic induction. On the other hand, Lenzââ¬â¢s law is an important law that explains how magnetic induction occurs, and how flux is generated in a magnetic field. In the definition of Faradayââ¬â¢s law above, any emf generated by a charge in a magnetic flux will have a polarity of the induced emf in a way that produces current, with a magnetic field opposing the charge producing it.... nition of Faradayââ¬â¢s law above, any emf generated by a charge in a magnetic flux will have a polarity of the induced emf in a way that produces current, with a magnetic field opposing the charge producing it. Therefore, Lenz law explains that the induced magnetic field in a loop of wire will at any time act to keep the magnetic flux in the loop constant. That is; an induced field will always act in the direction of an applied field in trying to keep it constant. This experiment was aimed at demonstrating the two laws and their applicability magnetic induction. Aim The aim of the practical was to investigate the behaviors of coils and magnets in a magnetic field created by current, testing Faradayââ¬â¢s and Lenzââ¬â¢s laws, and testing the behavior of a transformer that uses the two laws above to produce electric current. Equipment provided Coils, LV transformer DC voltage source Analogue multimeter/ galvanometer Bar magnets and small compass. Safety Precautions in the Exp eriment Safety shoes were worn throughout the experiment, no damaged equipment or tool was used in the experiment, and all electric connections were ensured to have a grounding connection. In addition, before the experiment, all electrical equipment was well grounded to avoid any shaking, which could affect data collection. Procedure Two magnetic bars were placed and a compass used to trace any presence of a magnetic field and its direction at different points around the two magnetic bars as shown below. In measuring Iin In measuring inductance, an electronic bridge was used to measure the inductance of an air-core coil. The coil resistance was recorded, and the relevant dimensions of the set up measured and recorded. The following formula was then used to detect the number of turns of the coil L =

Funding proposal local resilienc prject Essay Example | Topics and Well Written Essays - 4000 words
Funding proposal local resilienc prject - Essay Example For the coastal areas, it means erosion and evacuation of people living near the coastlines. According to Dorrell, R. and Wentworth, J. (2010, p.1) UK has roughly 16,000,000 people affected by floods as of September 2010, because 30% of England and Wales live near the coastal areas. Thousands lose their power supply during heavy rains, storm, or unusually cold winter. Some die. Based on the study of Kapucu, Naim PhD. (2009), Losses amounted to billions of Sterling Pounds in 1987 alone. An ideal Local Resiliency Project should be the orchestration of Local Authorities, Community Association members, and SMEs for the planning, management, and control of provisions that will meet the needs of all community members. There are those provisions that only the government can afford to prepare. These would be the well-trained Special Rescue Forces and major equipment for rescue and evacuation of people and properties, namely, heavy duty boats, diving supplies, army trucks, helicopters, ambula nce, night vision devices. And there are infrastructures that Joint Ventures can construct on sturdy, higher grounds where people can be evacuated. Ideally, these infrastructures should consist of durable housing alternatives and the durable Storage Depot of basic needs for survival day and night. Eventually, the homeowners themselves can become shareholders of all these investments. It can start with a Grant for the organization, planning, and initial implementations. Eventually, the chosen location of the Storage Depot should accommodate alternative housing that people in lowlands can eventually own through financing schemes. Section 3. Objective of Projects & Project Outcomes (300 words ) Lancashire Coastline communities will be the immediate beneficiary of this Local Resiliency Project. This project proposal clarifies the critical needs of the community wherein a Local Resiliency Project will be launched. It will then develop a contingency plan whereby any simulated disaster or actual calamity can have an equivalent logical response that should negate the unwanted impact for most homeowners and businesses. Thus, the objectives include the following: a. To describe the community and specific location that will be involved in the creation of a Local Resiliency Project, in terms of the usual natural disturbance based on past months and years; b. To elaborate the reported consequences of those calamities in the past; c. To identify needs of the community so as to remain productive during and after the disasters; d. To describe the logical remedy along with the implications of providing a solution; e. To estimate cost of having such provisions; f. To summarize the benefits of investing on such a proposed Local Resiliency Project; g. To develop a plan of action with timetable for implementation and maintenance; h. To identify people and organizations who should be help accountable and responsible for the various stages of the project proposal; i. To prove how th is project will result in a resilient community over many years to come; j. To specify limitations of such provisions for the community. Section 4. Statement of Needs, Characteristics of Beneficiaries ( 500 words ) Large towns make up the coastal settlements of
