Business for the Glory of God: The BibleÃ¢â¬â¢s teaching on the Moral Goodness of Business Book Review by: Marquetta Preston Liberty University Abstract Grudem, W. (2003). Business for the Glory of God: The BibleÃ¢â¬â¢s Teaching on the Moral Goodness of Business. Wheaton: IL: Crossway. ISBN: 978-1581345179. The book, Ã¢â¬Å"Business for the Glory of GodÃ¢â¬ , By Wayne Grudem, is a book that gives insight to how business as a whole can be a blessing to the world. God gave His people abilities to conduct business in order to glorify Him. Grudem explains that business and the attributes of business are Ã¢â¬Å"fundamentally goodÃ¢â¬ and provides many opportunities for glorifying God, but also many temptations to sin. He gives a biblical and moral standing pointÃ¢â¬ ¦show more contentÃ¢â¬ ¦Dr. Waddell explains that he feels work signifies honor, creativity, and love. Dr. Waddell states, Ã¢â¬Å"[vocation] expresses the belief that God is present in calling and equipping people to fulfill a particular purpose in life and this correlates with GrudemsÃ¢â¬â¢ statement, Ã¢â¬Å"that is why God made us with a desire to be productive, to make or do something useful for [ourselves] and other peopleÃ¢â¬ . Another aspect of business activity that Grudem inquires about is profit. When people think of profit the first thing that comes to mind is making money and a famous saying usually follows that train of thought; money is the root to all evil. This saying is derived from the Bible but the scripture is reworded and taken out of context. 1 Timothy 6:10 says, Ã¢â¬Å"for the love of money is the root of all evil: which while some coveted after, they have erred from the faith and pierced themselves through with many sorrowsÃ¢â¬ . Because some people feel that money is the root to all evil, they view making a profit as being evil. Grudem explains that making a profit not only helps others, but also corresponds with GodÃ¢â¬â¢s teaching to subdue the earth in making use of the earthÃ¢â¬â¢s resources. Therefore, profit is an indication that I am making good and efficient use of the earthÃ¢â¬â¢s resources, thus obeying GodÃ¢â¬â¢s original Ã¢â¬Å"creation mandateÃ¢â¬ to Ã¢â¬Å"subdu eÃ¢â¬ the earthShow MoreRelatedBusiness for the Glory of God Book Review Essay3161 Words Ã |Ã 13 PagesBook Review For Business for the Glory of God By: Wayne Grudem October 10, 2011 The Review: Business for the Glory of God Wayne Grudem wrote the book Ã¢â¬ËBusiness for the Glory of God,Ã¢â¬â¢ this book is based on biblical teachings.

EvilÃ¢â¬â¢s origin begins with Adam and Eve using their special gift, free will, to commit the first sin. They sinned because they were tempted from the free will to choose between following or disobeying GodÃ¢â¬â¢s orders. Paradise Lost is an epic written by John Milton that describes the fallen angel Satan and the fall of man. The Grand Inquisitor by Fyodor Dostoevsky is about an archbishop who talks with Jesus and wants to burn him as a heretic. Paradise Lost and The Grand Inquisitor both discuss free will and the stories of two benevolent characters that use their free will to choose evil. In Paradise Lost and The Grand Inquisitor, the main characters Satan and the Grand Inquisitor are evil because they use free will to choose evil over good.Ã¢â¬ ¦show more contentÃ¢â¬ ¦His perseverance to serve GodÃ¢â¬â¢s word makes him very similar to Satan. Both Satan and the Grand Inquisitor brandished how they were virtuous supporters. Once benevolent beings, Satan and the Grand I nquisitor soon turns toward evil. Satan and the Grand InquisitorÃ¢â¬â¢s plight from good to evil begin with their desire for power. In the case with Satan, he desires to overthrow GodÃ¢â¬â¢s kingdom and make it his own. Satan is prideful and ambitious and decides to attempt overthrowing God. Ã¢â¬Å"If he opposed; and with ambitious aim against the throne and monarchy of God, raised impious war in Heaven and battle proud.Ã¢â¬ (Milton, 41-43, Book I). By defying God, Satan conveys a message that says he wants GodÃ¢â¬â¢s throne. His desire for power turns him into an evil being fighting against the obedient servants of God. The Grand InquisitorÃ¢â¬â¢s ambition is similar aside the fact that he wants to take power away from Jesus. He wants power taken away from Jesus because he believes that Jesus doesnÃ¢â¬â¢t know deserve the power to control people by his teachings. Ã¢â¬Å"Oh we shall persuade them that they will only become free when they renounce their freedom to us and submit to us.Ã¢â¬ (Dostoevsky, 239) The Grand Inquisitor believes that Jesus was wrong in deserting his followers so the Grand Inquisitor turns to evil. The Grand InquisitorÃ¢â¬â¢s step towards evil truly begins when he places himself in JesusÃ¢â¬â¢ role in preaching and follows Satan instead. His desire for power shows the
Ã¢â¬ËPapuaÃ¢â¬â¢ and Ã¢â¬ËCoachÃ¢â¬â¢: Builders of Modern India During the last two thousand five hundred years and more of IndianÃ¢â¬â¢s history, two individual combinations made tremendous impact both on IndianÃ¢â¬â¢s civilization and polity. The first duo was that of Cattily and his trusted disciple Contractual Marry who together laid the foundation of the first great historical empire of ancient India. The other duo was that of Mahatma Gandhi and Charlatan Nehru who were instrumental in laying the base of a modern Indian state and giving shape to ideas in the realm of education, culture and democracy. We will write a custom essay sample on Gandhi And Nehru or any similar topic only for you Order Now Gandhi founded the Straight Ashram after turning from South Africa and successfully employed the principles of Straight in uniting the peasants of Qaeda and Champaign against the government. After this victory Gandhi was bestowed the title of Papua and Mahatma and his fame spread far and wide. Charlatan Nehru was not only the first Prime Minister of India, but in that opacity, was also a major world figure during the mid-twentieth century. Like many national leaders who first lead, or play a major role in leading, their nation to independence, Nehru was widely loved and respected and ended up not only serving as the nationÃ¢â¬â¢s deader for many years but also shaped much of the nationÃ¢â¬â¢s political life. Practically every official act of such a leader is a first and often becomes a precedent that his successors follow. 2 His great love for roses as well as children is a well-known fact. In fact he often compared the two, saying that children were like the buds in a garden. They should be carefully and lovingly nurtured, as they were the future of the nation and the citizens of tomorrow. He felt that children are the real strength of a country and the very foundation of society. Most importantly he did not discriminate between he sexes and believed in giving equal opportunities to girls and boys. Quite naturally, he was the Ã¢â¬ËbelovedÃ¢â¬â¢ of all the children who gave him the endearing name of Ã¢â¬ËCoach NehruÃ¢â¬â¢. Mahatma Gandhi and Charlatan Nehru are internationally well-known personalities, who had been venerated and respected by the intelligentsia. 10th of them were born in the nineteenth century and passed away in the twentieth century. The Mahatma was the leader and Nehru was the most devoted disciple of the Mahatma. Both of them were giants in their respective fields of the work. The Mahatma was assassinated and Nehru died. Both of them lived the biblical figure, three score and ten. The Mahatma was the father of the nation. Nehru w as the builder of the nation. 3 Nehru first time met Mahatma Gandhi in 1916 and admired his role in South Africa. When Gandhi started Straight in 1 919 against Reluctant, Nehru for the first time came into contact with the peasants (kinas) and this contact with the peasants influenced his later thought. He wrote, Ã¢â¬Å"Looking at them (kinas) and their misery and overflowing gratitude, was filled with shame and sorrow-shame at my own easy-going and comfortable life and our pretty politics of the city which moored this vast multitude of semi-naked sons and daughters of India. A new picture of India seemed to rise before me, naked, starving, crushed and utterly miserable. This experience with peasants indicated to Nehru the degree to which the nationalist movement coincided with SandhogÃ¢â¬â¢s rise to prominence in the congress and this strengthened Nehru consciousness of peasant India. Nehru played a significant role in the Non-Cooperation Movement launched in 1 921 , under the leadership of Mahatma Gandhi. A basic question could be put here: what was the influence of Gandhi upon Nehru during this period? SandhogÃ¢â¬â¢s stress on the religious and spiritual side of his movement was somewhat incomprehensible to Nehru. Nehru with his modern, scientific and rational approach to life simply did not speak the same language as Gandhi (1921). Nehru wrote: Ã¢â¬Å"but we felt that we knew him quite well enough to realize that he was a great and unique man and a glorious leader, and having put our faith in him, we gave him an almost blank cheese, for the time being at least. Ã¢â¬ For Nehru, the moral and ethical side of SandhogÃ¢â¬â¢s Straight had greater appeal. Nehru did not accept non-violence as an absolute creed but he became convinced that against the background of IndianÃ¢â¬â¢s traditions, it was the right policy to follow. SandhogÃ¢â¬â¢s continuous insistence on the necessity of worthy means being used to attain worthy ends deeply influenced Nehru. SandhogÃ¢â¬â¢s abhorrence of machinery and modern civilization had no effect on Nehru, except to convince him and others that such ideas would have to be firmly dealt with when independence was attained. 4 Gandhi and Nehru were completely different people as regards their social status, age, way of thinking and individuality. There were always deep ideological differences between them. In their attitude on life, Nehru and Gandhi differed from each other. Nehru was absolutely secular and scientific whereas Gandhi was out and out a man of religion. For Gandhi, religion and morality constituted the whole of life. They are inseparable. He laid great stress on truth and nonviolence and expected the Congress to be instrumental for the moral regeneration of the country. Nehru attached much importance to moral values but not so much to religion. For Nehru, religion was a womanÃ¢â¬â¢s affair. He wanted the Congress to play role effectively in the political and economic sphere. Gandhi formulated the principle of trusteeship for the rich and the propertied class. He was of the opinion that as the rich did not require all their wealth for the satisfaction of their personal needs, they should utilize the surplus wealth for the benefit of the society at large. Nehru, though allows important place to private sector, he consider the Seminary system as a semifinal system which was out of date and a great hindrance to production and general progress. Gandhi described self-reliance as one of the essential ingredients of the individualÃ¢â¬â¢s character. Charlatan Nehru made self-reliance the pivot around which the entire program of community development revolved. Both Gandhi and Nehru were cosmopolitans. They stood for internationalism. Gandhi did not want India to remain isolated from the rest of the world. Charlatan rejoiced on the freedom struggle of the subject countries. Both Gandhi and Nehru were humanists. Both of them gave greater importance to human qualities than to political expediency. The guru as well as his sashay stood for the toiling humanity. Their hearts bled for the poor and down trodden. There are many reasons as to why Nehru was drawn towards Gandhi. Nehru recognized the heroism and spirit of defiance of Gandhi. He also found that SandhogÃ¢â¬â¢s unique adhering and political action brought important results to the country. How to cite Gandhi And Nehru, Papers

Intel Corporation "A corporation is a business that, although owned by one or more investors, legally has the rights and duties of an individual. Corporations have the right to buy, sell, and own property. Corporations may make legal contracts, hire and fire workers, set prices, and be sued, fined, and taxed. A business must obtain a charter of incorporation from a state legislature or Congress to be legally recognized as a corporation."(Watson, p211) While corporations didn't exist until the mid to late 1800s, the idea of the corporation had existed since the early 1600s. It all started with English merchants who started trading companies to help fund the early colonies. If the colonies thrived, the stockholders reaped in the profit. (Watson, p211) A corporation is started when a sole proprietorship, a one-owner business, that is the most common form of business institution in the US, or a partnership, an association of two or more people in order to run a business, decides that they don't want to be personally responsible for any loss the company might have. (Watson, p211) Or they might decide that they want the company to "live on" after they die, that is for the business to have "unlimited life". Since neither of these goals can be reached with a sole proprietorship, or a partnership, the owner (or owners, as the case may be) decide that he (they) want to "convert" their business to a corporation. The owner(s) file a charter of incorporation from the government to be legally recognized as a corporation. (Boyd, March, 99) The owner(s) then sell shares of stock, documents representing ownership in the corporation, to investors. These investors buy and sell the stock to small investors, or stockholders. Since there is no limit to the number of shareholders to a company, the investors vote (for every share you own you get one vote) on a board of directors. The board of directors are in charge of hiring the people responsible for the every-day running of the corporation. These positions include, but are not limited to: the president, vice president, and other chief administrators. (Watson, p211-212) If a corporation reaps a profit, investors may receive a dividend, or a share of the monetary gain made by the company. The elected board of directors choose whether the money will go towards profit, expansion of the company, modernization of the company, or research and development. (Watson, p212) "With about 85% of the microprocessor market, Intel is definitely inside. Its microprocessors -- including the Pentium -- have been providing brains for IBM-compatible PCs 1981."(http://thestandard.net....) Intel started on July 16, 1968 when magnetic core memory was the leading technology at the time. They were trying to make semi-conductor memory practical with silicon memory. Unfortunately for Intel semi-conductor memory cost 100 times more than magnetic core memory, but the silicon had many advantages - smaller size, greater performance, and reduced energy consumption. Then, in late 1968,the Japanese company Busicom asked Intel to produce a series of chips (twelve chips for every unit) for a group of programmable calculators that they were producing. Normally, chips were made specifically for each product. Well, the designers at Intel decided that they would make a general purpose logical chip to replace all of the many different varieties of chips that would go into the different electronics. The logical chip was a major success; the only problem was that Busicom had the rights to the chip. Realizing that this chip could have a major impact on society, the founders Bob Noyce and Gordon Moore praised the new chip, while people in the corporation still wanted to stick with producing memory. Intel bought the rights to the chip from the struggling Japanese company for $60,000, and this "paved the way for Intel's developing vision of ubiquitous (universal) microprocessor-based computing."(.../cn71898a.htm). The 4004 microprocessor set was introduced near the end of 1971. "Smaller than a thumbnail and packing 2300 transistors, the $200 chip delivered as much computing power as the first electronic computer, ENIAC. By comparison, ENIAC relied on 18,000 vacuum tubes packed into 3,000 cubic feet when it was built in 1946. The 4004 executed 60,000 operations in one second, primitive by today's standards, but a major breakthrough at the time."."(.../cn71898a.htm). Directly after the 4004, Intel introduced the 8008 microprocessor, which processed eight bits of information at a time, twice as much as the original chip. This technological break-through put microprocessors everywhere, from fast food restaurants to airport control towers. Yet no one had thought of the personal computer, until; Intel Chairman Emeritus Moore remembers, "In the mid-1970s, someone

Essay Sample on Proteomics What is the Interest for Researchers Proteins are a basic building block of life on earth. They are the molecules that provide structure, produce energy, and allow communication, movement and reproduction within a cell. They, along with carbohydrates, amino acids, and phospholipids, are the key macromolecules that make up organisms. The body of proteins that make up an organism is referred to as its proteome. Proteomics is the study of these proteomes, including the identification of the proteins and their physiological functions. The study of proteomics had declined in recent years, but the inception of the Human Genome Project ten years ago revived interest for many researchers. Since then, the proteomes of numerous organisms have been determined. The Human Genome Project determined that the human body contains 30,000 genes. This translates to anywhere from 300,000 to one million possible proteins. The importance of proteomics largely lies in drug design and synthesis. Hopefully, new disease markers and drug targets can be identified that will help design products to prevent, diagnose and treat disease. This cannot be accomplished without knowledge of the proteome, however. A protein is a biological polymer that usually consists of hundreds of amino acid monomers. The general structure of an amino acid is a carbon atom to which four functional groups are bonded. Three of the groups include a hydrogen atom, an amine group, and a carboxylic acid group. The fourth group, or Ã¢â¬ËRÃ¢â¬â¢ group, is a hydrocarbon chain. This R group is unique to each particular amino acid and is what determines one amino acid from another. The primary structure of a protein is its linear sequence of amino acids bound by peptide bonds between a nitrogen atom of one monomer and a carbon atom of another. Disulfide bonds between cysteine residues within the molecule stabilize it. This structure determines the secondary, tertiary, and quaternary structures of the protein as well. Proteins are highly specialized, and a single change in an amino acid monomer can result in a completely different function, or no function at all for the protein. Thus, the primary structure is of utmost importance. The secondary structure of proteins consists of the primary structure formed into two possible regular structures. These are an alpha helix or a pleated sheet. These structures can organize themselves in a repeating fashion or randomly. Disulfide bonds determine the secondary structure, while hydrogen bonding also stabilizes the conformation. A proteinÃ¢â¬â¢s tertiary structure is the overall 3-D configuration of the complete protein. Amino acid residues that are far apart in a primary structure can have steric relationships in 3-D form, and the tertiary structure considers this. The tertiary structure is the most thermodynamically stable for the protein in a certain environment; it can change with environmental changes. This is how proteins are denatured. A protein may consist of several subunits. The quaternary structure of a protein is made up of all of these subunits bound together by electrostatic and hydrogen bonds. Multisubunit proteins are called oligomers and all of the component parts are monomers or subunits. Proteins may also contain non-amino acid functional structures such as a lipid or a carbohydrate. In order for proteins to be studied, they must first be isolated. In one dimension, the proteins are separated by charge based on their isoelectric points. The migration of different proteins in an electrically charged environment of graduated pH can separate them when their isoelectric points are different. The proteins move toward the pH at which they have no net charge. The main way this has been achieved is through 2-D polyacrylamide gel electrophoresis, or 2-D PAGE. This experiment can achieve the separation of several thousand different proteins in one gel, while high resolution 2-D PAGE can resolve up to 10,000 proteins per gel. Coomassie blue, silver, and SYPRO Ruby Red stains are typically used to visualize the proteinsÃ¢â¬â¢ migrations. Mass spectrometry is a technique used for the determination of the mass of a compound; however, it is also useful in protein identification. The spectrometer ionizes the protein, and this charged molecule is sent into an analyzer on the basis of charge repulsion. This analyzer resolves the proteins based on their mass to charge ratio, thus separating them. The detector passes the information to the computer for analysis and identification. Fragmentation can cause problems in protein separation, so ionization methods that minimize formation of fragments are most useful. These methods include matrix-assisted laser desorption/ ionization, or MALDI and electrospray ionization, or ESI. Once a protein has been isolated, its structure must be determined. Secondary and tertiary protein structures can be found by two methods: X-ray crystallography and nuclear magnetic resonance. Both methods require that the protein be better than 95% pure for the best results, so the isolation methods are extremely important. The experimental technique can include gel or column separation, dialysis, differential centrifugation, salting out, or HPLC. The choice and order of experiments is modified to suit the protein of interest. In order to study a proteinÃ¢â¬â¢s structure through X-ray crystallography, it must be crystallized. The most common methods of crystallization are batch methods and vapor diffusion. A supersaturated solution is formed which causes the protein to associate with other protein molecules. The formation of this solution often requires the addition of precipitants such as polyethylene glycol or certain salts. The identification of the amino acids in the protein are again important here, since they can determine the exact reagents and chemical and physical conditions used to crystallize the protein. The crystals are then mouted and snap frozen. This is accomplished by exposing them to cryogenic liquid or gas. In X-ray crystallography, the crystals are subjected to X-rays containing a heavy metal atom. This method can determine the proteinÃ¢â¬â¢s secondary and tertiary structure. The X-rays are scattered by the crystal in a pattern unique to the protein. One drawback is that the radiation can damage or backscatter; keeping the crystals supercooled minimizes this side effect and allows the crystals to be stored and reused. A model of the protein is then constructed using the data translated into electron density maps. This method is highly important in drug design, since it is very precise and can reveal crucial structural data. Nuclear magnetic resonance, or NMR, spectroscopy involves the alignment of nuclear dipoles of a sample in a magnetic field. These dipoles can change orientation back and forth in a magnetic field and absorb and emit energy for each turn. The spectrometer contains an antenna within the magnet; radio waves are pulsed by this antenna through the magnet. The sample absorbs these pulses as energy and then emits them sometime later. This time is measured and stored on the computer. Most often, pulse sequences are used that take advantage of the strong nuclear dipole of the hydrogen nucleus. The information gained from this experiment allows researchers to map the chemical bond connectivity and the spatial orientation of the proteins. This method is particularly useful in determining the function of active sites on enzymes. NMR spectroscopy has several advantages over X-ray crystallography. One is that NMR requires no crystallization in order for the proteinÃ¢â¬â¢s structure to be studied. Currently, this method can resolve proteins with molecular weights up to 30,000 Daltons; it is predicted that structures with molecular weights of up to 100,000 Daltons can soon be determined through this method in the coming years. Another advantage is that NMR is sensitive to motions on the millisecond to second range, which can be directly studied. Even motions as small as those of the nanosecond to microsecond scale can be studied indirectly. X-ray crystallography is also an extremely time-consuming process, and the crystalline structures can be difficult to maintain. However, the greatest advantage of NMR over X-ray crystallography is NMRÃ¢â¬â¢s ability to reveal the details of specific structural sites without solving the entire structure. Current studies in proteomics include the research being done by biochemists at the University of Washington in Seattle. These scientists are studying environmental effects on the transcription and translation of the mRNA molecule. This is the nucleic acid that codes for the manufacture of proteins within the cell. In an earlier study, they reported the use of Translational State Array Analysis, or TSAA. This method allowed for the simultaneous study of mRNA level and translation. They chose Saccharomyces cereviciae as their model and arrested it with the temperature-sensitive cdc 15-2 allele. A control was run in which forty-eight mRNA molecules changed upon release from arrest. However, when the temperature of the cdc 15-2 allele was lowered from 37 C to 25 C, fifty-four molecules of mRNA were affected. Therefore, regulating the translational level seems to affect directly the response of yeast cells to external cues. Another study done recently again involves the use of Saccharomyces cereviciae. This study, completed at Johns-Hopkins University, attempted to investigate whether indexing a proteome according to its C-terminal sequences could be of use in functional classification of proteins. The basis for this experiment is that the protein C-termini are capable of being recognition signatures for many biochemical processes. The extent to which carboxyl terminal sequences are conserved within the proteome is unknown, but this may be related to certain biological functions and therefore has great importance. The researchers analyzed the terminal sequences of Saccharomyces cereviciae and found that known and unknown terminal sequences existed. This result supports that there may be additional carboxyl terminal signals whose biological functions are not yet known.

Common Hull Shapes on Boats and Ships Naval architects have designed some crazy looking boats and they will continue to push forward with topside design principals. The hull, on the other hand, is well refined and needs a little tinkering. Hydrodynamics research is driven by supercomputers in the modern world, but the old refined designs originally built by eye and scale models are proving to be very efficient without the help of computer chips. These three shapes are most common. Displacement This is, of course, the classic boat hull shape. It is by far the oldest and most used hull in history. The reed barges of ancient Egypt were floating on the River Nile thousands of years ago. The main feature of this hull is its deep and mostly symmetrical shape. The measurement of hulls is expressed as deadrise, which, in the simplest terms is the angle and distance a portion of the hull rises to meet the deck. This kind of hull usually only has one chine. Tugboats are good examples of a displacement hull since much of the hull is submerged. Cargo vessels also use this shape since the increased buoyancy allows them to carry more weight. The tradeoff is there is also a lot of drag because so much of the hull is below the waterline when underway. The displacement hull is also a very stable platform because of the low center of gravity and weight of displacement vessels. A high center of gravity makes a vessel more unstable but slower to roll from side to side. Displacement hulls roll less but make the trip back and forth much more quickly. Semi-Displacement Semi-Displacement hulls are a hybrid between displacement hulls and planning hulls. The dead rise from the bow to midship would resemble a displacement hull, deep with a tall bow with a wide beam. The deadrise from midship back to the stern would have a shallow bottomed V shape and could be practically flat at the stern. It would also be narrower than the bow and have much less freeboard. These hulls are common on small and medium-sized vessels with a few exceptions. The U.S. NavyÃ¢â¬â¢s Littoral Combat Ship group is one larger example. It is a high-speed shallow draft vessel that nearly planes at full speed. The benefits here are higher speed capabilities since the forward portion of the vessel lifts from the water at high speeds. At rest or at lower speeds the vessel behaves more like a displacement hull. Many military applications use this design for medium-sized vessels since it is very versatile. The shallow deadrise of the stern gives exceptional prop clearance. In some cases, the forward hull has a deeper draft than the propellers. The drawbacks are a wet ride at the rear of the boat since there is little freeboard. Plus using these boats in some conditions can lead to a very rough ride. High speed over chop is not the Semi-displacement hullÃ¢â¬â¢s strong point. Some designs incorporate multiple chines to give a sort of stepped hull that has sweet spots for intermediate speeds Planning A planning hull has little draft. In the water, the vast majority of the hull will be above water. Think of every recreational boat you have ever seen and there is your planning hull example. The hull shape is widely used outside of the recreational boat industry by builders who want a fast and efficient hull. Fast patrol boats are common in military roles around the world and almost all designs are planning hulls. The planning hull skips over the water and at speed, it will only be in contact with the surface at the stern. At this attitude, it has very little drag from the hull. A hull of this design uses multiple chines to lift the hull clear of the water very quickly. The deadrise at the stern is shallow except for the area near the keel. This small but relatively deep V shape give a planning hull good turning characteristics at high speeds. Drawbacks are low carrying capacity and quick and frequent rolling when at rest in even slightly rough waters.

Late Adult Personal Interview - Essay Example Sigmund Freud taught that a child goes through stages of development. A childÃ¢â¬â¢s personality is formed by the age of 5 when the child enters the (sexual) latency stage (Storr, 1989). Erikson, a student of FreudÃ¢â¬â¢s daughter Anna, also taught that there are stages of development; however, he differed from the elder Freud, and taught that a personÃ¢â¬â¢s sense of identity is not fully formed as a child. Erikson taught that individuals continue to develop and evolve throughout their life. Whereas Freud stressed the importance of reaching milestones within a certain period during childhood, Erikson stressed the importance of cultural demands upon a child during life transitions (Erikson, 1959). According to the teachings of Freud, the older person could not accept concepts divergent from their basic philosophies. EriksonÃ¢â¬â¢s followers, however, would slowly advance through stages of acceptance of new concepts. Erikson taught that learning and development occur throughou t life. EriksonÃ¢â¬â¢s theories were evident in the interview with a woman who had experienced many tragedies, yet overcame them to life a full and productive life.

Joyce stated she had lived in her condominium since 1982, and was most relaxed there. The condo was quite comfortable with overstuffed chairs, large potted plants, thick carpets, antique tables, and three large Maine Coon cats.
