Term Paper Sample: Free Excerpt Part of the downward trend of fertility since 1957 was a result of the compressed fertility of the baby boom. Although it is not known whether today's young couples will have appreciably fewer children than couples born during the Depression years, there are two new facts in the picture today which point toward the probability of smaller families. The first is the continuation of the relationship described by Easterlin between fertility on the one hand and the supply of and demand for labor on the other. The bumper crops of babies are now maturing and swelling the ranks of job seekers and their competitive position is much less favorable than that of their counterparts in the late forties who entered the labor force in small numbers in a rapidly expanding economy. The second factor is the Pill. There is absolutely no evidence that the advent of the Pill initiated the decline in fertility; quite the contrary, the trend was evident for several years before the Pill was used by enough women to have made any substantial impact. But by 1964 this was no longer the case and by 1969 perhaps as many as a third of married couples were using this sophisticated contraceptive. The significance of the use of this method goes beyond its high degree of effectiveness in preventing unwanted fertility. The fact of its popularity among the young means that couples are adopting this method before, as well as early in, marriage, they are developing the contraceptive habit soon enough that increasing proportions of young couples are making decisions about first and second births that were formerly left to chance. This means not only that the length of time between births is increased, but also that the attitudes of successful family planning may be carried over into the later childbearing years. Moreover, an important by-product of postponing early childbearing is that it exposes the woman more to alternative interests potentially competitive with the mother role, such as working; this should also operate to reduce fertility further. One additional observation about the near future is also in order. Not only is research on new improved contraception progressing rapidly but the possibility of legalized abortion throughout the country seems closer at this moment than it has ever been closer indeed than anyone would have guessed even a year or so ago. And if that happens, as it well may, the fertility rate will undoubtedly decline further if the level of unwanted births has remained at anything like the rate estimated for the early 1960's.

Compare and contrast the idealism of Lenin and woodrow Wilson in terms Essay
Compare and contrast the idealism of Lenin and woodrow Wilson in terms of how they conceived and tried to implement a better world - Essay Example Both these leaders had different vision pertaining to reforms enabling the formation of a better society and a better world. An in-depth study of their vision would definitely formulate a rich comparative study joining the two separate halves of the world into one philosophical and theoretical unit. There is no doubt upon the fact that by the closing years of the Cold war era, Vladimir Lenin and Woodrow Wilson emerged as the two great revolutionary and political leaders of the world captivating and controlling the worldââ¬â¢s two most powerful blocks. Both the leaders were distinguishingly different both in their means and in their ends. The ideological difference of Wilson and Lenin was actually about the emerging difference between evolution and revolution. It was a clash between liberalism and communism. The organic thought process from the Burkeââ¬â¢s school of thought on one hand and the idealistic thought process from the Marxian school of thought became glaringly evident in their ideologies. Wilsonââ¬â¢s vision regarding the formulation of a better world was through the fulfillment of the progressive history. And much contrary to it, Lenin viewed it as a transition, an age that is quite critical in nature apprehensive of a degeneration of an older order and indication of a violent future. Lenin tried to implement a discourse pertaining to progressive revolution which he defines as inevitable in the history of the struggle of mankind. At this point, the contention of Wilson was different from that of Lenin. He viewed it as autocratic derailing of natural constitutional development. In their ideology and world vision, the realm where Wilson showed his calm and poise, Lenin displayed his aggression and violence. Many American citizens placed their gullible opinions towards Lenin and much contrary to it; Bolsheviks totally displayed their distrust towards Wilson and his Treaty of Versailles.

Same sex schools Essay Example | Topics and Well Written Essays - 500 words
Same sex schools - Essay Example Although same-sex schools have the advantage over co-ed schools in terms of academic excellence. Its disadvantages outweigh those advantages. For example in female same-sex schools, females don not have to struggle with their gender identities and thus can concentrate on their schooling. Girls no longer have to ask; "is my hair ok How does my makeup look Am I going to look like a geek if I answer another question Do I have to play sports to impress the girls" (Fidelman) In contrast, adolescents in co-ed schools are always flooded with these issues on their mind instead of concentrating on their academic lessons which should be the most essential task (Fidelman). However, the disadvantages of same-sex schools are far more plenty than its advantages. Schools should be a training ground to enable the students to be ready for the real world. In the real world, not only female dominate the world. In same-sex schools, emphasis is usually on female role model. The students' role models for best teachers are female, their role models for best athletes are female and the list goes on. Furthermore, single sex education is inconsistent with the goals of this nation's public school system to develop an educated population able to transcend barriers of race and gender in society" (Single sex education is an unwise policy).

Musical Genre Classification of Audio Signals Essay Example for Free
Musical Genre Classification of Audio Signals Essay Musical genres are categorized by human. It depends on human hearing. There are common characteristics shared by categories. These characteristics are related to instrumentation, rhythmic structure, and harmonic content of the music. Currently many music is still classified by manually. Automated system for musical genre classification can assist or replace manual work for classifying musical genre. In this paper, the automatic classification of audio signals into hierarchy of musical genres is explored. Three feature sets for representing timbral texture, rhythmic content and pitch content are proposed. Also propose classification through two-times KNN classification method and show enhancement of accuracy. Using two-time KNN classification method increases accuracy about 5% than one-time ++++KNN classification which two-time KNN classification accuracy is 77.9% and one-time KNN classification accuracy is 73.3%.

These characteristics are related to instrumentation, rhythmic structure, and harmonic content of the music. Genre classification is magnified when music industry moved from CD to web. In web music is distributed in large amount so importance of genre classification is magnified. Currently many music is still classified by manually. Automated system for musical genre classification can assist or replace manual work for classifying musical genre. In era of web, it enabled to access large amount of all kinds of data such as music, movies, news and so on. Music database has been grown exponentially since first perceptual coders early in the 90ââ¬â¢s. As database grows it demanded tools that can enable search, retrieve and handle large amount of data. Classifying musical genre was great tool for searching, retrieving and handling large music data base [1-3]. There are several more method such as music emotion classification [4], beat tracking [5], preference recommendation [6], and etc.. Musical genres classification (MGC) are created and used for categorized and describe music. Musical genre has no precise definitions or boundaries because it is categorized by human hearing. Musical genres classification are highly related to public marketing, historical and cultural factors. Different countries and organizations have different genre lists, and they even define the same genre with different definitions. So it is hard to define certain genres precisely. There is not an official specification of music genre until now. There are about 500 to 800 genres in music [7, 8]. Some researchers suggested the definition of musical genres classification [9]. After several attempt to define musical genres researchers figured out that it shares certain characteristics such as instrumentation, rhythmic structure, and pitch content. Genre hierarchies were created by human experts and they are currently used to classify music in the web. Auto MGC can provide automating classifying process and provide important component for complete music information. The most significant proposal to specifically deal with this task was released in 2002 [3]. S everal strategies dealing with related problems have been proposed in research areas. In this paper, automatic musical genre classification is proposed showed in Figure 1. For feature extraction, three sets of features for representing instrumentation (timberal), rhythmic content and pitch content are proposed. Figure 1 Automatic Musical Genre Classification II. Music Modeling Genre Segmentation An untrained and non-expert person can detect the genre of a song with accuracy of 72% by hearing three-second segmentation of the song [11]. However computer is not design like human brain so it canââ¬â¢t process MGC like human. Despite whole song may somehow influence the representativeness of feature, using whole song can extract most of features that music has. Also to extract short segment of music for automation system is unsuited for the purpose because difficulty of finding exact time of music that represents genre of music. Without research finding certain section of music representing its characteristic using whole song to modeling is proper way to MGC. There are too many music genres used in web [7, 8]. Classification genre has to be simplified and in this paper proposed genres which are popular used in MP3 players in the market. Figure 2 Taxonomy of Music Genre III. Feature Extraction Feature extraction is the process of computing numerical representation that can be used to characterize segment of audio and classify its genre. Digital music file contains data sampled from analog audio signal. It has huge data size compared to its actual information. Features are thus extracted from audio signal to obtain more meaningful information and reduce the over-loading processing. For feature extraction three sets of features for representing instrumentation (timberal), rhythmic content and pitch content will be used [3]. 1. Timbral Texture Features The features used to represent timbre texture are based on the features proposed inà speech recognition. The following specific features are usually used to represent timbre texture. ââ Spectral shape features [1-3] Spectral shape features are computed directly from the power spectrum of an audio signal frame, describing the shape and characteristics of the power spectrum. The calculated features are based on the short time Fourier transform (STFT) and are calculated for every short-time frame of sound. There are several ways to extract feature with spectral shape feature. 1. Spectral centroid is centroid of the magnitude spectrum of STFT and its measure of spectral brightness.

Ch. 10 project- Booker T. Washington :: essays research papers
Booker Taliaferro was born a mix slave in Franklin Country on 5th April, 1856. His father was a white man who and no one knew who he was and his mother the slave of James Burroughs. His mother married the slave Washington Ferguson. When Booker entered school he took the name of his stepfather and became known as Booker T. Washington. After emancipation, his family was so poor that he worked in factories and mines at the age of nine. When he was 16 his parents allowed him to quit work to go to school. They had no money to help him so he walked 200 miles to attend the Hampton Institute in Virginia and paid his tuition and board there by working as the janitor. The principal of the institute was Samuel Armstrong an who was against slavery and had been commander of African American troops during the Civil War. Armstrong believed that it was important that the freed slaves received an education. Armstrong was impressed with Washington and arranged for his tuition to be paid for by a wealthy white man. Booker T. Washington carried on this idea and later he would teach in his home town, then at the Hampton Institute, and then in 1881, he founded the Tuskegee Normal and Industrial Institute in Tuskegee, Alabama. As head of the Institute, he traveled the country unceasingly to raise funds from blacks and whites both; soon he became a well-known speaker. In 1895, Washington was asked to speak at the opening of the Cotton States Exposition, a good thing for an African American. His Atlanta Compromise speech explained his idea, that blacks could protect their rights through their own economic and moral progress rather than through legal and political changes. Although his calm stand angered some blacks who feared it would encourage the enemy of equal rights, whites approved of his views. His major achievement was to win over diverse elements among southern whites, without whose support the programs he thought and brought into being would have been impossible.

Public bank management Essay
1.Introductions The model of the Five Competitive Forces was developed by Michael E. Porter that becomes an important tool for analysing an organizations industry structure instrategic processes. This model is applicable to the banking industry. Public Bank do compete with the other financial institution in Malaysia, however they also must cooperate with one another in many respects. There is an underlying problem which is the banks in Malaysia are so similar that there is essentially nothing one of them can do that the others cannot easily duplicate 2. Five Forces Analysis a. Threats of new entrants Malaysia has not put a barrier to entry for any financial institution manly banks in Malaysia, thus making it easy for any financial institution to penetrate into the industry. b. Bargaining power of suppliers a bank has three suppliers of its product, money: 1. Its depositors has no bargaining power whatever in reality. If they make time deposits the bank will set the price or interest rate it will pay. 2. The credit market the credit market as a source of supply of the raw material, money, is open to all at all time if they are qualified participants. The source of supply can be argued to be infinite. 3. The central bank The Central bank is effectively the resource of last resort. Apparently, at least for the moment, it will continue to supply liquidity to the banking system in virtually unlimited quantities at very reasonable cost. c. Bargaining power of buyers In the banking industry, customer have has very limited bargaining power. However the customers may option in changing to other banks that they think is offering a better offer than Public Bank. c. Threat of substitute product For the most part there is no real threat of substitute products in the banking industry. However there probably will be continues evolution ofà products from paper to electronic in coming years. This is an area of potential competition for whomever banks that choose to use it in their services. d. Rivalry among competitors Generally all banks offer somewhat the same products and services to their customers, thus there is not much differentiation between Public Banks and the other competitors. This is making the competition much higher. Public Bank is actually ranked as the top banks earners in Malaysia in 2009 alongside with Maybank, Bumiputra Commerce, RHB Capital and Hong Leong Bank. 3. Table 1: Method used to identify opportunity and threat for Public Bank using external environment factors and industrial environment factors.(Factors under industry environment are derived from Porters Five Forces). 4. Opportunities 1. Economic growth Malaysia had definitely have been more economically stable and improving, thus financial institution such as Public Bank are needed to aid the overall development of the country. 2. Government policy Encouraging borrowings, loans, investment and consumption demand. 3. Awards and accolades Through recognition, Public Bank can project a positive image to their customers 4. Market share Public Bank has the highest market share for the private sector unit trust business, thus having a larger customer base. 5.à Low switching cost Nowadays it is easy for any customer to switch to other banks with just a click away, making the switching cost to be faster and cheaper, making it easy for the customers to switch to Public Bank. 5. Threats 1. Substitute product/service are available There is a potential competition to whomever banks that choose to upgrade their product and services to cater to their customers need. Maybank for example provide a customer friendly interface through their website www.maybank2u.com, and it became the most visited website in Malaysia. 2.Substitute performance Maybank, Bumiputra Commerce, RHB Capital and Hong Leong Bank are Public Bank competitors and each is recognized for their performance. This will make the competition even higher. 3. Customer switching cost Other than being an opportunity, switching cost can also be a threat for Public Bank as the customers can also easily switch to other financial institution. 4. Government legal& barriers There are no barriers that the government put for any legal financial institution to enter in the industry, making any new entrants penetrate into the market share easily. 5. Exit barriers High exit barriers in the industry are making the competition between Public Bank and the other competitors are even higher. 6. Conclusion Porter Five Forces Model are used to identify how the forces affect the attractiveness and profitability of Public Bank, and through this forces, the factors that influence these forces are used in the table 1, to identify Public Bank opportunities and threats. By identifying Public Banks industry environment, the company can improve and sustain their product and services for their customer, ultimately improving their performance.

Biography of Granville T. Woods, American Inventor
Granville T. Woods (April 23, 1856ââ¬âJan. 30, 1910) was a black inventor so successful that he was sometimes referred to as The Black Edison. He dedicated his lifes work to developing a variety of inventions, many relating to the railroad industry. By the time of his early death at age 53, Woods had invented 15 appliances for electric railways and received nearly 60 patents, many related to the railroad industry. Fast Facts: Granville T. Woods Known For: Highly successful black inventorAlso Known As: The Black EdisonBorn: April 23, 1856 in Columbus, Ohio or AustraliaParents: Tailer and Martha Woods or Martha J. Brown and Cyrus WoodsDied: Jan. 30, 1910 in New York, New YorkNotable Invention: Synchronous Multiplex Railway Telegraph Early Life Granville T. Woods was born on April 23, 1856. Most reports indicate he was born in Columbus, Ohio, the son of Tailer and Martha Woods, and that he and his parents were free African-Americans by virtue of theà Northwest Ordinanceà of 1787, which prohibited slavery from the territory that included what would become the state of Ohio. However, Rayvon Fouchà © wrote in a Woods biography that, based on census records, Woods death certificate, and journalistic accounts published in the 1890s, Woods was born in Australia and apparently moved to Columbus at a young age. Some biographies list his parents as Martha J. Brown and Cyrus Woods. Early Career Most sources agree that Woods had little formal education, leaving school at age 10 to work as an apprentice, studying to be a machinist and a blacksmith, and literally learning his skills on the job. Woods held a variety of positions in his early teens, including working as an engineer in a railroad machine shop and on a British ship, in a steel mill, and as a railroad worker. While working, Woods took courses in fields such as engineering and electronics, realizing that education was essential to developing the skills he would need to express his creativity with machinery.ââ¬â¹Ã Some reports say he had up to two years of college course training in either electrical or mechanical engineering or both, possibly in an East Coast college from 1876 to 1878. In 1872, Woods obtained a job as a fireman on the Danville and Southern railroad in Missouri, eventually becoming an engineer and studying electronics in his spare time. In 1874, he moved to Springfield, Illinois, and worked in a rolling mill. Four years later, he took a job aboard the British steamer Ironsides. Within two years, he became its chief engineer. Settling Down His travels and experiences finally led him to settle in Cincinnati, Ohio, where he dedicated himself to modernizing the railroad and its equipment. Woods invented more than a dozen devices to improve electric railway cars and other devices for controlling the flow of electricity. His most noted invention at this point was a system for letting a train engineer know how close his train was to others, which helped reduce collisions. He also developed a system for overhead electric conducting lines for railroads, which aided in the development of overhead railroad systems in cities such as Chicago, St. Louis, and New York. Woods eventually set up his own business, the Woods Electrical Co., in Cincinnati to develop, manufacture, and sell electrical apparatus. In his early 30s, he became interested in thermal power and steam-driven engines. He filed his first patent for an improved steam boiler furnace in 1889. His later patents were mainly for electrical devices. He also developed the Synchronous Multiplex Railway Telegraph, which allowed communications between train stations and moving trains. This made it possible for trains to communicate with stations and other trains so everyone knew exactly where the trains were at all times. Among his other inventions were an automatic air brake used to slow or stop trains and an electric car that was powered by overhead wires. It used a third rail system to keep the cars running on the right tracks. Other Inventors Telephone inventor Alexander Graham Bells company, American Bell Telephone Co., purchased the rights toà Woods patent on an apparatus that combined a telephone and a telegraph. The device, which Woods called ââ¬Å"telegraphony,â⬠allowed a telegraph station to send voice and telegraph messages over a single wire. Proceeds from the sale gave Woods the luxury of being a full-time inventor. Success led to lawsuits. One was filed by famed inventor Thomas Edison, who sued Woods on a claim that he, Edison, was the inventor of the multiplex telegraph. Woods eventually won the court battle, but Edison didnt give up easily when he wanted something. Trying to win over Woods and his inventions, Edison offered Woods a prominent position in the engineering department of Edison Electric Light Co. in New York. Woods declined, preferring to maintain his independence. Early in his career during the summer of 1881, Woods contracted smallpox, which was in its last years as a major health threat in the United States. The often fatal illness sidelined Woods for nearly a year and left him with chronic kidney and liver disease that might have played a role in his early death. He suffered a stroke on Jan. 28, 1910, and died at Harlem Hospital in New York two days later. During his smallpox illness, Woods was quoted as saying he had to take extreme measures to support his family. Another reference, in 1891, mentioned that he was being sued for divorce. Generally, though, newspaper accounts referred to Woods as being a bachelor. Legacy Granville T. Woods dozens of inventions and patents made life easier and safer for countless Americans, especially when it came to railroad travel. When he died, he had become an admired and well-respected inventor, having sold a number of his devices to such industrial giants as Westinghouse, General Electric, and American Engineering. Decades later, many of his other patents have been assigned to major manufacturers of electrical equipment that play a substantial role in daily life. To the world, he was known as the Black Thomas Edison, and his numerous inventions and improvements to existing technology seem to support that characterization. Sources Granville T.
