CHAPTER. 2 Literature review GENERAL Fly ash is a waste product from thermal power plants where pulverized coal is used for the as per the literature review GouravHYPERLINK http://biblioteca. universia. net/autor/Gourav,%20K. html,  Studies, 2007. Fly ash is being utilized in the blended cements, additive for concrete and manufacturing of concrete blocks and bricks. Fly ash-lime-gypsum bricks are being manufactured and marketed throughout the country. The literature review on fly ash-lime-gypsum (FALG) mixtures as intended to manufacture bricks or blocks for masonry applications indicates several gaps in understanding the various aspects of the technology. The present thesis is an attempt to understand the behavior of compacted stabilized fly ash mixtures for the manufacture of fly ash bricks and characteristics of masonry using such bricks. A brief introduction to the technology of compacted stabilized fly ash bricks for structural masonry is provided. The main focus of the investigations is on arriving at the optimum stabilizer-fly ash mixtures considering density, stabilizer-fly ash ratio, curing conditions, etc. We will write a custom essay sample on Literature Review of Fal-G or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page as the variables. Therefore the parameters/variables considered in the investigation include: (a) density of the compacted fly ash mixture, (b) stabilizer-fly ash ratio, (c) curing duration (normal curing and steam curing) and (d) dosage of additives like gypsum. The investigations clearly show the possibility of producing bricks of good quality using compacted fly ash-lime gypsum mixtures. Wet compressive strengths of 8- 10 MPa was obtained for compacted fly ash-lime-gypsum bricks at the age of 28 days. Wet strength to dry strength ratio for these bricks is in the range of 0. 55 – 0. 67. Initial tangent modulus for the fly ash-lime-gypsum bricks in saturated condition is in the range of 8000 – 12000 MPa. There is a large scope for selecting optimum mix ratios of Fly ash, sand, lime and other additives to obtain a specific designed strength for the brick. The thesis ends highlighting major conclusions of the investigations. A general study conducted on M30 strength of neat FaL-G has indicated that 1. 5 times of its dosage by weight, as against OPC, keeping the other aggregate same, renders a mortar or concrete of parallel grade strength. A Study on workability for M15 grade concrete has not shown any slump, unlike OPC. The additional 50% input of FaL-G cement might have rendered relatively better cohesion for wet concrete to show this phenomenon. Hence a different approach to study workability of FaL-G concrete has to be developed. Even at low workability, this can be considered as roller compacted concrete. FaL-G can replace OPC in many avenues. The reinforcement behavioral studies in reinforced FaL-G cement concrete (RFCC) are in progress but the postulations indicate that the constituent of FaL-G being 1. 5 times more than OPC by weight which in other words 3 times by volume of account of two to one ratio in densities, the specific area of cement matrix is relatively larger in RFCC than in RCC. Thereby reinforcement is more closely coated with cementitious gels and more safely ensured for water impermeability to veto the chances of corrosion. However FaL-G is weak abrasive product hence may be avoided on high abrasive prone areas, till its abrasive resistance is virtually improved. It is cheap in cost; transportation cost can be reduced by decentralizing the FaL-G cement activities. Fly ash-based brick and cement are far superior in engineering properties over their conventional competitors. This knowledge needs to be disseminated globally, more so in second and third world countries, through tangible technical explanations (Bhanumathidas and Kalidas 2003). Although results of FaL-G bricks and hollow blocks were promising, and the technology could not be implemented due to initial consumer resistance in adapting to new materials. Ambalavanan and Roja (1996) in their study of FaL-G bricks utilized waste lime and gypsum with fly ash. They have observed that in most cases the use of waste lime does not give technically desired results and some improvement is needed to increase the strength of FaL-G bricks. The treatment to be given to waste lime increases the cost of FaL-G bricks significantly as compared to conventional bricks, which is hindering the commercialisation of this new material. Some researchers have reported that there is fall in strength in FaL-G composites at later age. This aspect should be considered in the field application of FaL-G products. For wider application of FaL-G bricks and hollow blocks in the housing sector, extensive research is further needed. ENGINEERING MECHANICAL PROPERTIES OF FAL-G Radhakrishnas (2010) preparation of FAL-g composite included both blocks cubes, with different parameters like finesse of fly ash, aggregate to binder ratio, degree of saturation, age testing the blocks and cubes for unconfined compression to determine the compressive strength. The strength data was generalized for a reference value of water-to-FaL-G ratio. A phenomenological model was developed to account for synergy between the materials used. Its robustness was verified with an independent set of experimental data. The predicted strength values are in close agreement with the experimental strength. He reinforced the possibility of using the model in the field to re-proportion the FaL-G mix of any consistency. Ismail Demur and Serhat Baspinar, 2007: investigated the effect of different type of pozzolan additions to cement free lightweight block made from fly ash–lime–gypsum mixture and observe the changes in physical, mechanical, thermal properties and microstructure Thermal conductivity of the fly ash–lime–gypsum mixture was improved by the addition of the expanded perlite. Optimal strength-thermal conductivity combination was obtained by the usage of silica fume and expanded perlite together. Improved strength properties were obtained by using hydrothermal curing conditions and super plasticizer addition.

Antiohos et al; 2007: In their test they studied Mechanical and durability characteristics of gypsum-free blended cements incorporating ulphate-rich reject fly ash. No gypsum was added in the mixtures, since it is believed that sulphate ions necessary for the prolongation of the setting process (commonly provided by gypsum) could be provided by fly ash enriched in sulphates. Their tests results revealed that waste materials not up to relevant standards could still contribute to the production of quality products of energy and economical efficien cy. * This article is not included in your organizations subscription.

D. P. Benz et al; (2010); presents paper about thermal Properties of High-Volume Fly Ash Mortars and Concretes. Paper focuses on a characterization of the thermal properties, namely specific heat capacity and thermal conductivity, of such mixture. Because the specimens being examined are well hydrated, estimates of the specific heat capacity based on a law of mixtures, with a â€Å"bound specific heat capacity value being employed for the water in the mixture, provide reasonable predictions of the measured performance. Observed measured values should provide a useful database for evaluating the thermal performance of high volume fly ash concrete structures. RESEARCH PAPER 1999: points about the effects of processing and materials variations on mechanical properties of lightweight cement composites. The mechanical properties were improved by increasing the amount of silica fume, fly ash, and fibers.

Concrete Research Letters Vol. 1(3) this paper reports the results of an experimental investigation carried out to study the effects of fly ash on strength development of mortar and the optimum use of fly ash in mortar. His test results show that strength increases with the increase of fly ash up to an optimum value, beyond which, strength values start decreasing with further addition of fly ash. Among the six fly ash mortars, the optimum amount of cement replacement in mortar is about 40%, which provides 14%higher compressive strength and 8% higher tensile strength as compared to OPC mortar. Jia-sheng Chen1 et al; February 2010: His study results show that yellow phosphorus slag can be used as the cement substitute for potential coagulation property.

In continuous experiment it was observed that the % removal was 95–99%. A mathematical treatment of this adsorption phenomenon has been developed and it was observed that the experimental results showed satisfactory agreement with the theoretical predicted results. M. Ahmaruzzaman; 2010: In this paper, the utilization of fly ash in construction, as a low-cost adsorbent for the removal of organic compounds, flue gas and metals, light weight aggregate, mine back fill, road sub-base, and zeolite synthesis is discussed. The adsorption capacity of fly ash may be increased after chemical and physical activation. Converting fly ash into zeolites not only alleviates the disposal problem but also converts a waste material into a marketable commodity. Investigations also revealed that the unburned carbon component in fly ash plays an important role in its adsorption capacity. Future research in these areas is also discussed. | As per the experimental studies done by S. Geetha, Ramamurthy; 2010: Chemical activation is done using Na2SO4 to enhance the strength of the cold-bonded aggregate by accelerating the pozzolanic reaction and formation of more ettringite. It was observed that increase in binder and Na2SO4 dosages increased the strength and decreased the open porosity thereby reducing the water absorption As per, Lal C. Ram Reginald E. Masto; 2010: Studies the application of FA has improved the physical, chemical and biological qualities of soil to which it is applied. FA generated in India tends to be mostly alkaline, with lower levels of trace elements than are often found in FAs from other countries. The concentrations of potential chemical stressors, predominantly metals, in Indian FAs are often less than established or proposed permissible limits and are thus better suited for soil application. A major logistic limitation to the use of FA could be the cost involved in transport of ash from production to utilization sites. High Volume Fly Ash Concrete and Its Mechanism Posted: 2009- It is known that the fly ash emissions from industrial by-products are very large. To fully exploit the potential activity of industrial waste, fly ash has to be used to reduce the amount of cement concrete.

These bricks have sufficient structural strength for use in building and construction. In another embodiment, waste materials are encapsulated in a mixture of fly ash, bottom ash, gypsum, lime, and calcium carbonate and compressed into bricks that may be disposed of in an environmentally acceptable manner. Further, the compressed bricks containing waste material may be coated with an impermeable membrane of a synthetic polymeric material. Further, the invention provides a mobile, trailer-mounted apparatus for compressing the mixtures into bricks. Mohammad M.

The results of this study suggest that the addition of 10% bentonite to coal fly ash reduced the hydraulic conductivity of the coal fly ash to less than 1_10? 9 ms and improved the chemical compatibility for mine waste containment. Use of these materials in road making is based on technical, economic, and ecological criteria. Various Industrial wastes for use in the construction of highway have been found to be successful. ECO-FRIENDLY BUILDING MATERIALS AND TECHNOLOGIES. Eco-housing Assessment Criteria 2009. Information about Fly Ash Lime Gypsum Brick. Fly ash-lime-gypsum bricks / blocks are very good products, giving the highest strength among various bricks. These require relatively higher investment and expensive raw materials to give arrange of high strength products. This is most suitable for mechanized operations, though semi mechanized operations are also possible. Fly ash lime gypsum bricks are made up of 60% fly ash, 10-20% lime and 10-20% gypsum. These bricks have medium range strength. Minimum compressive strength (28 days) of 70 kg/cm2 can easily be achieved and this can go up to 250 Kg/cm2 (in autoclaved type). Advantage of these bricks over burnt clay bricks: Lower requirement of mortar in construction, Plastering over brick can be avoided, Controlled dimensions, edges, smooth and fine finish can be in different colors using pigments and cost effective, energy-efficient environment friendly (This avoids the use of fertile clay). Polycor Vetrazzo; -2010: did research about recycled material investigates the composition preferably used for recycle that is Fal-g and observes, has high recycle content. The sheet-form material made in accordance with the invention can be used to provide exposed solid surfaces, for example, surfaces for shower walls and floors, counter-tops, table-tops, and the like, where low hydraulic permeability and high compressive and tensile strength are required. The cement content is relatively low, preferably in the range of about 3% to 20% by weight, and the pozzolan to cement ratio is relatively high, preferably equal to or greater than unity and can be suitably used as alternative construction material. Godfrey MadzivireLeslie et al; 2010: studies about Balfo Application of coal fly ash to circumneutral mine waters for the removal of sulphates as gypsum and ettringite. They observed Subsequent treatment of circumneutral mine water to pH greater than 11 resulted in more than 60% sulphate removal. Treatment of circumneutral mine water to pH greater than 11 with FA followed by seeding with gypsum crystals and the addition of amorphous Al(OH) 3 resulted in removal of sulphate to levels below the Department of Water Affairs and Forestry (DWAF) water quality effluent limit (500  ppm0). Keat-Teong LeeKok-Chong Tan, et al, 2007, they devised a Model that was found useful to predict the daily operation of flue gas desulfurization processes by using CaO/CaSO4/coal fly ash sorbent to remove O2from flue gas. Puvvadi V et al; 2010: studied about Gypsum treated fly ash as a liner for waste disposal facilities. They investigated the use of gypsum, which is known to accelerate the unconfined compressive strength by increasing the lime reactivity, and further improving the hydraulic conductivity. They made an attempt in the present context to reduce the hydraulic conductivity by adding lime content up to 10% to two selected samples of class F fly ashes. They investigated that the higher amount of lime in the presence of sulphate is observed to produce more cementitious compounds which block the pores in the fly ash. The consequent reduction in the hydraulic conductivity of fly ash would be beneficial in reducing the leach ability of trace elements present in the fly ash when used as a base liner. J. Sanjurjo Sanchez et al. 2010. Studied about the deposition of particles on gypsum-rich coatings of historic buildings in urban and rural environments and made comparisons. They studied XRF and SEM analyses of these coatings and their comparison with both the composition of dust coatings formed by the deposition of gaseous and particulate matter in an urban and a rural locality allows assessing which pollution sources are the most damaging for these materials, knowing the elemental composition of these emissions. Aly Ahmed et al; 2011: did Investigations of using recycled gypsum â€Å"bassanite† which is derived from gypsum waste plasterboard and waste plastic trays for ground improvement; this can be also used for soil improvement. Recycled gypsum content, curing time and frost heave property throughout capillary rise test were investigated to determine the behavior of treated soil with recycled gypsum. In addition, size, content and aspect ratio of strips of waste plastic trays were investigated. Adding strips of waste plastic trays to samples treated with recycled gypsum enhanced both splitting tensile and compressive strengths as well increased the value of secant modulus. The size and content of strips of waste plastic trays have significant effect on the potential of capillary rise and the enhancement of strength and stiffness of tested soil.

Experiments were performed to determine the effect of calcined phosphogypsum on the strength of fly ash lime binders. But lowering the lime to calcined phosphogypsum ratio of blends with the same fly ash content yielded a relatively lower compressive development at late ages. Strengths of samples cured first at 45[degrees] C in over 90% R. H. for 12 h and then at room temperature were better than those cured at room temperature all the time. X-ray analysis suggests that the activation of calcined phosphogypsum to the systems was due to the formation of ettringite and dehydrate calcium sulfate during the hydration process.

Some of the major conclusions of the investigations are (a) compressive strength of compacted stabilised fly ash mixtures is sensitive to dry density of the specimens and the strength increases with increase in density irrespective of stabilizer content and type of curing, (b) Optimum lime fly ash ratio yielding maximum strength is 0. 5, (c) addition of gypsum accelerates rate of strength gain for compacted fly ash-lime mixtures (d) for 28 days wet burlap curing optimum gypsum content yielding maximum strength is 2% and maximum compressive strength is achieved for lime contents in the range of 10 – 17%, (e) steam curing (at 80  °C for 24 hours) gives highest compressive strengt h for compacted fly ash-lime mixtures. Compressive strength, flexure bond strength and stress strain relationship for the fly ash brick masonry using cement-lime mortars were evaluated. The investigations clearly show the possibility of producing bricks of good quality using compacted fly ash-lime gypsum mixtures. Wet compressive strengths of 8- 10 MPa was obtained for compacted fly ash-lime-gypsum bricks at the age of 28 days. Wet strength to dry strength ratio for these bricks is in the range of 0. 55 – 0. 67. There is a large scope for selecting optimum mix ratios of fly ash, sand, lime and other additives to obtain a specific designed strength for the brick. Curing effect; on improving strength of fal-g. As per, Is? k Yilmaz and Berrin Civelekoglu; 2009, this paper deals with the performance of the gypsum as an additive for treatment of the expansive clay soils by means of swell potential and strength. Gypsum can be used as a stabilizing agent for expansive clay soils, effectively. The literature contains a vast number of stabilizing techniques such as lime, cement, and fly-ash for treatment of expansive clay soils. They however concluded the use of gypsum as a stabilizing agent is currently not clear. As per Pimraksa and P. Chindaprasirt; 2008, Water content, pre-curing period, lime content, gypsum content and calcined temperature are the factors investigated. The nature of hydration products and morphological characteristics of the lightweight bricks are also investigated. He concluded that the diatomaceous earth possesses pozzolanic property and can be used for making lightweight bricks. Concrete blocks of fal-g As per the literature review of Sunil Kumar. 2007, The compressive strength, water absorption and weight of FaL-G hollow blocks were determined . FaL-G hollow blocks are light in weight and being hollow, impart thermal insulation to the buildings. In this paper, a study based on the results of an experimental investigation on FaL-G hollow blocks is presented. The durability of these blocks in terms of loss in compressive strength in sulfate environments is also presented in this paper. It is observed that FaL-G hollow blocks have sufficient strength for their use in general building construction. High Volume Fly Ash Concrete and Its Mechanism Posted: 2009: As the fly ash emissions from industrial by-products is very large, large volume fly ash concrete to fully exploit the potential activity of industrial waste fly ash to reduce the amount of cement, concrete to reduce the Cost of production; to improve concrete workability, durability, and physical and mechanical properties. High Volume Fly Ash Concrete to save both cement, but also consume a large amount of fly ash, for the reduction of Environmental load of very effective. High Volume Fly Ash Concrete as a new type of material has its own unique advantages, with its performance study, large volume fly ash concrete and continuously improves the performance. In one embodiment the invention provides solid bricks produced by compressing together fly ash, bottom ash, gypsum, calcium carbonate, and lime. These bricks have sufficient structural strength for use in building and construction. In another embodiment, waste materials are encapsulated in a mixture of fly ash, bottom ash, gypsum, lime, and calcium carbonate and compressed into bricks that may be disposed of in an environmentally acceptable manner. Further, the compressed bricks containing waste material may be coated with an impermeable membrane of a synthetic polymeric material. Further, the invention provides a mobile, trailer-mounted apparatus for compressing the mixtures into bricks. As per the Technical paper ECO-FRIENDLY BUILDING MATERIALS AND TECHNOLOGIES. 2009. Fly ash-lime-gypsum bricks / blocks are very good products, giving the highest strength among various bricks. These require relatively higher investment and expensive raw materials to give arrange of high strength products. This is most suitable for mechanized operations, though semi mechanized operations are also possible. Fly ash lime gypsum bricks are made up of 60% fly ash, 10-20% lime and 10-20% gypsum. These bricks have medium range strength. Minimum compressive strength (28 days) of 70 kg/cm2 can easily be achieved and this can go up to 250 Kg/cm2 (in autoclaved type). Advantage of these bricks over burnt clay bricks: Lower requirement of mortar in construction, Plastering over brick can be avoided, Controlled dimensions, edges, smooth and fine finish can be in different colors using pigments and cost effective, energy-efficient environment friendly

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

Confucianism - Essay Example Thus politeness being a universal communication phenomenon it reflects particular cultural values that come with or rather which are linked to diverse cultures. Being a relatively vital aspect in cross-cultural communication, politeness enables people from different cultures to establish, consolidate or maintain harmonious interpersonal relations that reduce misunderstandings and conflicts in the society. A snapshot on various aspects of politeness in the two cultures, Chinese and English, depicts that the rules of communication differ as they are influenced by the values and beliefs of individuals from these communities. For instance, the English people always address others according to their genders; Mr., Mrs., Miss and Ms, followed with a surname, depending on age and marital status. On the other hand, the Chinese address people using a surname and the title of the occupation; â€Å"Wang yi sheng† to mean Doctor Wang, â€Å"Lee xiao zhang† to mean Principal Lee and â€Å"shi fu† can be used to address strangers. In addition, the Chinese culture, especially for children, â€Å"shushu† and â€Å"a yi† are always used to address uncle and aunty respectively. Another aspect of politeness in the two cultures is farewell and greetings. Whenever the English people meet, they always use phrases like â€Å"Nice to meet you,† â€Å"Good Morning,† â€Å"Good evening† and â€Å"Good afternoon.† For the Chinese, the phrase â€Å"ni hao† is always used whenever people meet. Moreover, when the China people meet their acquaintances, one can say â€Å"qu na li† to ask where one is going or â€Å"chi le ma?† to ask whether one has eaten or not. Thus, whenever an native speaker of English hear the Chinese phrases, he or she might interpret them as invitation lunch or dinner and any other interference in their personal affair. I met one of my colleagues, an English speaker on my way to a restaurant. I was

Development task 2... with label sketch - Assignment Example The depth of the concrete has to be greater than 500 millimeter. From ground level, the depth of the concrete must be greater than 1500 millimeter (Cyril, 2003: 110). Since the ground condition has firm clay, therefore there is a need to consider the depth of foundations. Clay exhibits the property to shrink or contract depending on the moisture content present in it (Kenneth, 1993:25). At the same time, if the surrounding area has trees, there is a possibility that the trees would absorb the moisture from the clay and hence, the foundation may experience settlement to a significant level. For this case, it is essential to consider the depth of the foundation. A trench fill foundation is thus ideal for this type of site condition. Research suggests that â€Å"trench fill foundations are quicker to prepare than deep strip foundations. This means that there is less disruption once the building work starts and not as much labour time will be needed. It is less likely that subsidence will occur in cases where there may be changes in the soils substrata† (Mosley & Bungey, 2000, 48). The site has different ground conditions and has different soils. Thus, it has a weak bearing capacity. For this purpose, the ideal foundation would be strip, grid or mat foundation. In this case, the suggested foundation is mat foundation. Because of varying ground conditions, majority of the isolated footings would have large areas and thus, it would become uneconomical (Terzaghi et.al, 2006, 256)l. According to the British Code, â€Å"Where the subsoil is very weak the load needs to be spread over a greater area. This is achieved by casting a slab of concrete over the whole ground area and thickening the slab where walls are to be placed†(Perry & Perry, 2009, 118). The design of any reinforced concrete structure aims at a suitable and economical design and for this purpose, mat foundation is ideal. A mat foundation is often used by designers when isolated footings may

International Monetary Fund Essay Example for Free

International Monetary Fund Essay The question â€Å"To what extent has the International Monetary Fund contributed in revamping the Nigerian economy since the 1980’s?† is a question that helps us to evaluate the true impact of international monetary policy.   In order to further understand the meaning of this question, this paper will examine the following subjects – 1) the meaning of the question, 2) the significance of the question for International Relations scholars, 3) how the question relates to other published work in the area, and 4) what methods would be employed to answer the question. First of all, the question is directly focused on economic impacts.   However, the question is not simply a matter of metrics, because the question is directed at procedural changes as well.   The question is focused on the restructuring of the Nigerian economy.   To only use economic metrics would fail to address the consequences restructuring entails.   When the IMF releases money to a country, they stipulate conditions that the country must meet. Therefore, the question is also directed at the matching the directives of the IMF with the implementation within Nigeria.   The question is not asking if the IMF has had a positive or negative impact on Nigeria, so value judgments can be left aside.   However, there are several hidden economic impacts.   Structural changes to the workforce, changes in occupations, and new roles within the economy are all more difficult to measure, but can be considered a result of economic policy.    Therefore, the question means 1) what are the economic stipulations of the IMF from the 1980’s until now, 2) has the Nigerian government met the requirements of the IMF, 3) what restructuring has occurred within the Nigerian economy as a result of the IMF, 4) what economic measures can be attributed to these changes, and 5) what are the indirect economic impacts of the IMF policies. International relations scholars are interested in this question because the answers yield important data on the impacts of policy.   International relations scholars are often consulted on questions of policy.   It is therefore in their best interest to know the impacts of policies made in the past.   In this regard, they are historians.   First of all, it is critically important for International Relations scholars to understand what the IMF has attempted to revamp within the Nigerian economy by tracing the stipulations as they were made. Additionally, the scholar can look at the Nigerian government’s ability to meet the demands of the IMF.   How well were they able to integrate the changes required by the IMF.   Were there consequences that required new policies in the future?   In tracing these policy changes, the scholar can also piece their own picture together of what the IMF did well (what was effective), and what changes needed to be made in direction in order to achieve effectiveness.   They can also have a unique insight into the culture and politics of Nigeria, as well as the internal culture and politics of the IMF. At this point, the International Relations scholar can also know what economic measures are affected by differing types of policies and requirements.   Additionally, they can make recommendations on what types of correlations can be found between initiative and their impact.   Perhaps some of the most valuable information for International Relations scholars, however, is related to the indirect impact of the IMF’s policies. When looking at the restructuring of the Nigerian economy, the International Relations scholar is able to examine the changes within the population, how people moved around, the changes in families, etc.   This type of information allows for a more comprehensive picture of economic change and the effects policy can have on cultural change.   Also, this may highlight the challenges represented by a more powerful entity interacting with a less powerful entity on a global scale. There has been much written about Nigeria since the 1980’s.   There are environmental reports, malnutrition reports, and economic reports.   However, these all approach Nigeria from a different perspective than the direction of this question.   This question seeks to directly explore the impact of IMF policies and economic aid on the revamping of the Nigerian economy.   As such, this question seeks to provide supporting information of the changes in Nigeria.   It seeks to trace change related to IMF policies alone.    It is impossible to completely know what current conditions in Nigeria are caused solely or even primarily by the IMF policies, however by focusing on the IMF, widespread impacts can be evaluated from IMF policies.   It is taking the infusion of money and change of monetary policy as the starting point and looking for the economic aspects affected.   One of the main sources for research on these types of development programs is found with the World Bank.   A particularly useful document is â€Å"The Evolution of Poverty and Welfare in Nigeria, 1982 – 1992.†[1]Using this document and also information from the IMF, the scholar can tie together the policies of the IMF and the effects. In order to study such a complex issues, a rigorous approach will need to be taken.   It is the most difficult to know the indirect impacts of the IMF’s economic policies.   It is undesirable to claim that changes were a result of IMF policy, if in fact, they owed their existence to a governmental or environmental change.   However, the economy is so closely entwined with all aspects of life, the implications of the IMF policies will be seen to have far-reaching consequences. Therefore, we can begin by examining the Nigerian economy and economic statistics in 1980, and comparing them with the present day to get snapshots of the economic health of Nigeria at these two points in time.   These snapshots, however, encompass other economic influences other than the IMF programs.   Then the specific policies of the IMF and their objectives are compared to the resulting economic changes to see if the stated goals have been achieved via metrics. Also involved in this analysis is the ability of the Nigerian government to implement the changes required by the IMF.  Ã‚   This area of analysis is perhaps the easiest, as the initiatives of the IMF are easily available.   However, information on the implementation and the implementation’s challenges may be more difficult to find.   Looking at a timeline of IMF policies, one can also deduce what was effective or not effective.   If a policy was ineffective, then in a later cycle we should find a correction or an abandonment of the program. The internal structure of the government and economy can also be viewed.   The way that money flows and what directions can be measured.   It is important to see structural change since the 1980’s.   The Nigerian government worked with the IMF to develop the National Economic and Empowerment Development Strategy in 2004.[2]   This document reviews previous policy and also lays the groundwork for future work between the IMF and the Nigerian government. This report focuses on structural changes – highlighting the importance of revamping the Nigerian economy. Additionally, looking at the basic economic unit – the household – can show structural changes ass well.   By looking at these structural changes, the real question about revamping the economy can be answered.   Of course, this type of analysis also looks at the indirect effects of economic change.   These are difficult to measure, but by tracing newspaper stories and major events in Nigeria, it may be possible to trace events back to economic policy decisions. Overall, the question of the effectiveness of the IMF’s policies to restructure the Nigerian economy is a very important question with implications for future policy consideration and also a deeper understanding of the past. Now that the world is becoming smaller and national boundaries are being crossed with money and policy, it is more important than ever to understand the impact of economic policy.   Additionally, with the prevalence of capitalism and modernization, the effects of economic policy on third world nations must have a thorough understanding.

Eulogy for Grandfather :: Eulogies Eulogy

Eulogy for Grandfather To my family, relatives and friends who knew Joseph, may the grace and peace of Almighty God the Father, His Son Jesus Christ and the Holy Spirit be with you all. Although I can not be here today physically, I am here with you in spirit. I would like to share a few words about my grandfather, whom I loved very dearly. He was a man who loved his family very much and made the best of what he had to provide for them. During my lifetime, I observed how diligently my grandfather worked in the barbershop, in the garden and around the house. He would also go out to cut hair for those who were in the hospital, house bound and in the nursing home. I also observed his generosity when he would give friends and relatives food from his garden. He always had a kind word and gentle smile towards those whom he encountered. His charity, I am convinced, is an effect of his strong Catholic faith in our Lord Jesus Christ. Charity towards others is the greatest sign of God's presence in our lives. His charity overflowed into his family. He truly loved his wife, his children and grandchildren. Even when there would be disagreements in the family, he would be the fi rst one to put end to them. He always made it a point that peace should remain in the family no matter what would happen. These words of wisdom were made manifest by the 65 years of marriage he enjoyed. From the time I was born until the day I left for Rome last August, my grandfather had always cut my hair. As he cut my hair, he would tell me stories about Westerly, family matters, tending the garden and, of course, his birthplace Acri, which is situated in the center of Calabria, Italy. He would tell the same stories over and over to me, my father, my aunt and uncle and my cousins. He never tired of telling these stories and they always seem to bring a smile to his face. Now when I look back, these are the memories I have of him, of who he was, of what he did, and how he lived. In April of this year, I had the unique opportunity of traveling to Acri on a day trip. When I arrived in this small town situated in the mountains of Calabria, I began to see all the places my grandfather told me about when he used to cut my hair.

Bringing the Jobs Home

The book under review is: â€Å"Bringing the Jobs Home† or â€Å"How the Left Created the Outsourcing Crisis–and How We Can Fix It†. In this book the author, Todd G. Buchholz, gives a conservative economist’s views on the origin of outsourcing of jobs meant for Americans to people in other countries, and how the trend can be reversed to return jobs to Americans in the United States. His analysis of the problem of outsourcing of jobs places the origin of the phenomenon squarely at the doorsteps of liberals, who he termed â€Å"The Left†.Todd G. Buchholz, to all intents and purposes, sees the problem of outsourcing of jobs from America to foreign countries not as a global phenomenon, deriving its origin from globalization; but as a problem contrived and sustained by American liberals and democrats, whose policies deprived American workers of their god-given rights to jobs in their own country. The critical questions one should ask are: What are the re al reasons that led American corporations to consider outsourcing of jobs? In what ways can the trend be reversed?If one objectively views Buchholz’s analysis of the origin of outsourcing problem as rather strange and ultraconservative, his recommended solutions to the problem are more than weird. In a world that is fast shrinking into one big global village, and where American cultural and economic influence have penetrated even the most remote outposts of human civilization, and in all areas of human endeavor; Todd G. Buchholz’s recipe for fixing the outsourcing crisis, are to say the least isolationist; a throwback to the era of American protectionism.Todd G. Buchholz’s views on solving the outsourcing crisis, when placed in the context of today’s world, are like driving a car in the reverse gear on an expressway. Description and Analysis Background Information about the author The author of the book Todd G. Buchholz is an internationally known economi st and financial expert. He once served as a director for economic policy to the United States president. He has also served as financial adviser to such well known investment companies as Goldman Sachs and Soros Fund.In addition Todd G. Buchholz has managed an investment that is famous worldwide. He has written for such top of the shelf newspapers as The Wall Street Journal, The New York Times among his many other publications on financial policy. Todd G. Buchholz has thrown new light onto old problems in the area of financial and economic management. One of his other well known books is: New Ideas from Dead Economics. Todd G. Buchholz is generally regarded as a well respected conservative economist.His views on economic policy directions are well known and sought after by companies and governments. Purpose of the Book The purpose for which Todd G. Buchholz wrote this book was to highlight the problem Americans have to face by the policy of outsourcing jobs to workers overseas to t he detriment of jobless Americans. Todd G. Buchholz attributes much of the problem to the policy of globalization which was initiated by previous governments of the United States controlled by the Democratic Party, which he collectively labeled â€Å"The Left†.Some of the unfavorable conditions emanating from wrong-headed policies of â€Å"The Left† which he felt led to the crisis of outsourcing of jobs by American companies include: an education system which continues to produce graduates who do not have the necessary competence required for modern job requirements; thus forcing American companies to look elsewhere for reliable workers; a suffocating tax regime which forces companies to pay for an over bloated social security programs; pro-union laws which restricts well educated foreigners of American Universities from staying back to work in the United States; and to compound it all, an American legal system that favors plaintiffs in frivolous lawsuits and which awa rds unnecessarily high financial damages against companies. Todd G.Buchholz’s solution to these problems, and which he claims will lead to reversal of direction of policy of outsourcing, is that legislation should be passed in all the problematic areas highlighted above in favor of protecting the free market tradition of the United States. Todd G. Buchholz first identified the root causes of why American companies and businesses outsource, as a combination of the negative effects of such societal forces as â€Å"nasty tax collectors, dull school bureaucrats, and sharp lawyers† which working together, force American companies to take their business overseas, where government policies and societal conditions are more favorable to free enterprise. He then gave the following recommendations: To reduce the high cost of hiring American workers, should legislate tax cuts and have less regulations on doing business in the United States. Todd G.Buchholz also advocates stricter education standards in American schools and colleges so as to improve the quality of graduates being churned out annually. He also recommends the reduction of the lawyer population in the United States through giving disincentives to American law practice, by restricting admission and raising standards required to qualify for admission to law schools and at the Bar. Significance of the work This book written by an expert who knows his onions is significant in many respects. By joining the debate on the vexed question of outsourcing of jobs overseas by American companies Todd G. Buchholz, has given us a fresh dimension to a problem which has now assumed a crisis dimension.American youths and older workers should not be put at such a terrible disadvantage by what has now come to be seen as wrong headed government and policies. Government of the United States needs to do more to give incentives to American companies wishing to continue business operations at home. Review of Critical Qu estions The two critical questions poised at the onset are: What are the real reasons that led American corporations to consider outsourcing of jobs? In what ways can the trend be reversed? From the analysis of Todd G. Buchholz’s work, it is obvious that there is a crisis of underemployment of labor in the United states due to outsourcing of jobs overseas by American companies.Moreover, urgent steps need to be taken to reverse the trend, and to encourage American businesses to bring back outsourced jobs to the United States. Todd G. Buchholz’s work addresses these two questions. His remedies, though conservative in outlook, give us a starting point in addressing the issues raised in his book. Summary In summary, Todd G. Buchholz has given us a starting point in frontally confronting the crisis of outsourcing jobs overseas by American companies which face daunting problems of overpricing of incompetent labor at home in addition to government interference in business and labor matters.

Dennis Gioia “The Ford Pinto Fire” Essay

In 1968, Ford Motor Company made plans for a car that would be inexpensive, small, and appeal to all car buyers. The planned project was to meet the 2000/2000 rule, meaning that the Pinto could weigh no more than 2,000 pounds, and cost no more than $2,000. This rule was instituted because of the extreme competition from foreign car makers such as Toyota and all of the automotive companies at the time. However, the 2000/2000 rule left designers with limited ability to design a car the way it should be designed. The Pinto was brought into production faster than any other car had ever been produced; twenty five months from the inception of the idea of the Pinto to production when the industry average at the time was forty-three months. The engineers had to cut corners in the design and were rushed building the Pinto, which later resulted in many mistakes that were overlooked. The first Pinto was put on the market in 1971. The Pinto’s problems originated with placement of the gas tank. It was customary to place the gas tank between the rear axle and the bumper to give the vehicle more truck space. However, on the Pinto the gas tank was only nine inches away from the rear axle and on the rear axles transfer case were bolts that stuck out facing the rear bumper of the vehicle. When the Pinto was rear ended, the gas tank would be forced up to the rear axle, and the transfer case bolts would puncture the gas tank. Also the fuel filler pipe was poorly designed and could easily become detached in a rear end collision, causing gasoline to spill over the ground. This was the cause of the numerous large fires and the gas tank tendency to explode. Explosions of the gas tank occurred at any collision at or above thirty one miles per hour. The doors on the Pinto would tend to jam shut when rear ended at high speeds, causing victims to burn alive if not killed on impact. Due to the serious defects and the numerous deaths involved with the Pinto, there were many law suits against Ford Motor Company. Dennis Gioia, an engineer and MBA graduate, was involved in the decision not to recall the vehicles. Ford came up with a Cost Benefit analysis. The benefits accounted for 180 burn deaths prevented,  180 serious burn injuries prevented, 2,100 burned vehicles prevented. If those number are multiplied by $200,000 per death, $67,000 per injury, and $700 per vehicle, the final benefit to society, or amount of money Ford would have to pay if they did not recall any of the their vehicles, was $49.5 million. Compared to the cost to recall 11 million cars and1.5 million light trucks, at $11 per vehicle would equal $137 million on recalls. Ford believed they were justified in not recalling the cars due to the amount they would spend on recalls far out-weighed the amount they would spend to compensate customers for death, injury or harmed cars. ANALYSIS OF GIOIA’S DECISION Ford eventually agreed to recall the Pinto on June 10, 1978. They sent out the recall notices on August 22, 1978. Ford originally gave four reasons why they did not want to recall the Pinto: 1) Ford had based an earlier advertising campaign around safety, which failed. 2) The bad publicity involved with a recall would be too much negative publicity to overcome. 3) At the time of the product designs and crash tests, the law did not require them to redesign the fuel system. 4) It was customary in the automotive industry to place the gas tank between the rear axle and bumper. We will evaluate Gioia’s earlier decision to choose not to recall the vehicles based on the reasons noted above. Dennis Gioia had started as an advocate for human rights and protection, prior to his appointment to the position at Ford Motor Company. He was aware of the design defects with the Pinto, however, he succumbed to the corporate rhetoric of buyer risk and consumer demand as rational for the decision to keep the Pinto on the market. Generalization Test Generalization theory – A rational choice must be generalizable , the reason for a certain action should be consistent with the assumption that everyone who has the same reasons will act the same way. The decision to keep the Pinto on the market passed the generalizations test: 1. The Cost Analysis used was acceptable in the production market 2. The vehicle met applicable safety laws at the time of production 3. The placement of the gas tank was in compliance with car production standards 4. Consumer demand for the vehicles increased profits 5. The recall would reduce profits and negatively impact the company . Utilization Test The decision also passed the utilization Test Utilitarian theory – We all have some ultimate end that is called utility. An action is ethical only if no other available action creates greater total utility. 1. A greater number of consumers were happy with the vehicle than were injured or killed 2, Recalling the cars would create more financial loss than keeping them on the market with the defects 3. The cost to make the cars safer would have increased the cost of production and not meet the 2000/2000 concept mandated by the corporate leaders 4. The delay in production would have deceased the company’s ability to compete in the small car market and decrease profits, Value Test Value ethics theory – virtue is a part of our essence and help describe who we are The decision not to recall the Pinto failed the value test. 1. A rational person with virtue and concern for human rights would not place a arbitrary price on the value of human life as opposed to profits. 2. Although a corporation is not a person it is an entity that relys of the people to value and purchase the products or services it provides 3. The decision to put an obviously flawed vehicle on the market and justify it by placing the responsibility on the consumer to accept the risk is irresponsible and reprehensible for any entity to adopt as a marketing strategy. 4. There is no virtue in a corporation or its management, that would routinely select profit over human safety and death, when they know it can be rectified.

The Sixties essays

The Sixties essays The Sixties split the skies. Only Civil and two world wars so neatly divided our history into a Before and After.

The Sixties drove people apart husbands from wives, children from parents, students from teachers, citizens from their government. Authority was strengthened by World War II.

Despite the growing restiveness of the nations African American population, and despite undercurrents of protest and discontent from many other groups, most Americans faced the future with optimism. The civil rights movement spawned social activism. Among the many effects of the civil rights movement as it gained momentum in the early 1960s was its impact on Greensboro sit-ins in 1960, accelerating with the 1961 Freedom Rides, and with the Mississippi Summer project. These movements opened up some eyes to Americans so they could see what was going on in the country at this time. Most of the things that went on in the sixties dealt with the War.

Advertising is a Marketing Tool - Essay Example Advertising campaigns are prepared with a specific intention in mind. They target specific products or the overall product attributes of an enterprise. Wendy’s has prepared advertising campaigns to highlight the fast service of its carry out window order service with the added message that is open after midnight. The use of publicity is much different than advertising. The purpose of creating publicity is to raise awareness about the company as a whole. An unwritten rule about publicity is that any publicity either positive or negative is good for the company because it gets the name of the company out in the conscious of the customers. Sometimes companies create stunts to create publicity in an unethical manner. For instance a CEO might go on public television on a rampage burning the competitor’s products and services in order to create a media reaction. These types of publicity stunts should not be used since they hurt the integrity of the marketing profession. 2. In your response you mentioned a lot of differences between advertising and publicity. I like your response a lot. One of the differences between the two concepts is the planning associated with each of them. Advertising requires a systematic plan that requires a specific budget, timeline, and other variables. On the other hand publicity a lot of times occurs as a spur of the moment event. For instance if a company wins an award from a recognize magazine for best customer service within its industry this occurrence will create publicity for the firm. The company did not plan for the publicity. 3. participation article In the article Marketing Ethics in Emerging Markets – Coping with Ethical Dilemmas the author mentions some cases concerning lack of marketing ethics including the Nestle occurrence in India. Nestle took advantage of the ignorance of portions of the Indian population to launch a fear campaign in order to persuade people to switch from tap water to the bottle water the company was launching. To me this type of behavior is unacceptable. Corporations should try to educate the local population in emerging economies to make the customers more aware of the virtues of acquiring consumer products. Corporations should not use disinformation to confuse the consumers in an attempt to gain a competitive advantage. Sele, K. (2006, March). Marketing ethics in emerging markets -- Coping with ethical dilemmas. IIMB Management Review, 18(1), 95-104. 4. Participation – Dave I agree with you that the publicity that BP received for committing one of the biggest blunders in the history of mankind is a disgrace. Unfortunately there is a rule in marketing that states that any kind of media coverage irrelevant if is good or bad provides a positive impact to the company in the long run in terms of free publicity. Another example of a company that gained a lot of free publicity for doing a bad act was Nike Corporation during the late 1990’s. The company was involved in a sweatshop scandal that was perceived by the general public as an abuse of power and a disgraceful act considering the prices the company charges for its tennis shoe models. 5. Participation – Article The article Marketing Wisdom for 2006: 110 Marketers & Agencies Share Real Life Tips was a very interesting piece of literature.

The opinion of a software engineer in regards to what should be included in the content of the website is not as important as the recommendation of the marketing department. Other technologies such as CRM system should be welcomed by marketing people

Deviant behavior within cults Essay Example | Topics and Well Written Essays - 2500 words

Deviant behavior within cults - Essay Example According to an estimate some three thousand (3,000) of such cults have been reported to exist all over the world with a total population of at least three million people attached to them as their followers. The secret religious ceremonies in Greek were technically called the Mysteries. The history of Mysteries is traced back to the days of ancient Greece in the year 600 B.C. when in a Greek city Eleusis, the people practiced a cult of Eleusinian Mysteries. Those Greek who practiced this cult, which involved the worship of Demeter, the goddess of fertility, were promised blessings in the life hereafter. In ancient Rome the group, comprising mostly of soldiers, and belonging to the 'Mithraism Cult' also practiced Mysteries. The members of this cult worshipped the god of fire and light called Mithra. (Raitt, Jill., n.p.n.d.) It was not easy to become a member of a cult in ancient times. Before their admittance into a particular cult, people had to undergo rigorous tests of their patience and staunch adherence. Some of the steps and mechanism involving induction of new members into the cult included: 2. The new entrants then take an oath and pledge for their adherence to the cult so as to become permanent member. The members develop a sense of belonging to that particular cult whose membership they attain. The followers of the cult then begin to imbibe within them the characteristics of cult, their mentality converting into strong allegiance to the group as denoted by the phrase "Us vs Them" 3. Belief of the members: Members gradually are made to develop a belief that it is only they or their group which is on the path of truth. And the other forms of truth as described in other various divinely religions become meaningless to them. The process of operative exclusivists comes into play allowing awareness of several unrevealed dogmas and special information only to those who are interested and proved their loyalty within the group. 4. The natural outcome of this belief is the segregation of such a group from the existing society. The feelings of hostility for other members of society who are not members of such a cult are emanated from the process of indoctrination from cult's beliefs. 5. Self-negation: Cults demand sacrifice of personal wishes, desires or wishes from its members. It is through the practice of this principle of self-negation that members exhibit willingness to sacrifice their self-comfort, getting along without money, and crushing their ambitious dreams for fulfilling cults motives and the so-called salvation The Modern Cults As the time passed, the meaning of cult underwent a change especially after 1960s. The new definition
