The History of the Soda Fountain

From the early 20th century up until the 1960s, it was common for small-town residents and big-city dwellers to enjoy carbonated beverages at local soda fountains and ice cream saloons. Often housed together with apothecaries, the ornate, baroque soda fountain counter served as a meeting place for people of all ages and became especially popular as a legal place to gather during Prohibition. By the 1920s, just about every apothecary had a soda fountain. Soda Fountain Manufacturers Some soda fountains back in the day were the Transcendent, which had miniature Greek statues on top of them and four spigots and a cupola topped with stars. Then there was the Puffer Commonwealth, which had more spigots and was more statuesque. The four most successful manufacturers of soda fountains—Tuft’s Arctic Soda Fountain, A.D. Puffer and Sons of Boston, John Matthews and Charles Lippincott—created  a monopoly of the soda fountain manufacturing business  by combining to form the American Soda Fountain Company in 1891. A Little History The term soda water was first coined in 1798, and in  1810 the first U.S. patent was issued for the mass manufacture of imitation mineral waters to inventors Simmons and Rundell of Charleston, South Carolina. The soda fountain patent was first granted to U.S. physician Samuel Fahnestock (1764–1836) in 1819. He had invented a  barrel-shaped with a pump and spigot to dispense  carbonated water, and the device was meant to be kept under a counter or hidden. In 1832 New Yorker John Matthews  invented a design that would make artificially carbonating water more cost-effective. His machine—a metal-lined chamber where sulfuric acid and calcium carbonate were mixed to make carbon dioxide—artificially carbonated waters at a quantity that could be sold to drugstores or street vendors. In Lowell, Massachusetts, Gustavus D.  Dows invented and operated the first marble soda fountain and ice shaver, which he patented in 1863. It was housed in a miniature cottage and was functional, and made of eye-pleasing white Italian marble, onyx and glistening brass with large mirrors. The New York Times wrote that Mr. Dows was the  first to create a fountain that looked like a Doric temple. Boston-based manufacturer James Walker Tufts (1835–1902) patented a soda fountain in 1883  that he called the Arctic Soda Apparatus. Tufts went on to become a huge soda fountain maker, selling more soda fountains than all of his competitors combined. In 1903 a revolution in soda fountain design took place with the front-service fountain patented by New Yorker Edwin Haeusser Heisinger, who operated a soda fountain in Union Station. Soda Fountains Today The popularity of soda fountains collapsed in the 1970s  with the introduction of fast foods, commercial ice cream, bottled  soft drinks, and restaurants. Today, the  soda fountain is nothing other than a small,  self-serve soft drink dispenser. Old-fashioned soda fountain parlors within apothecaries—where druggists would serve syrup and chilled, carbonated soda water—are most likely found in museums nowadays.

What Is Self Esteem Essay - 655 Words

What is self-esteem? Self-esteem is a term used in psychology to describe someone’s level of confidence and respect for themselves. Pride, shame and dignity are some of the emotions self-esteem encompasses. In 1943, Abraham Maslow, an American psychologist created the Maslow’s hierarchy of needs; it was composed of physiological, safety, love/belonging, esteem and self-actualization, physiological being the most basic needs. He believed that psychological health is not possible unless people accepted, loved and respected you and if you didn’t accept yourself. Self-esteem is influenced massively by a person’s experiences. Positive experiences brings up one’s self-esteem while negative experiences do the opposite. Babies aren’t capable of†¦show more content†¦People with a healthy and positive self-esteem level are confident in who they are, have firm beliefs and trust their own judgment. They can enjoy numerous activities and donâ₠¬â„¢t feel inferior or superior to people around them. They don’t dwell too much on the past and aren’t unnecessarily worried about the future. Having a higher self-esteem increases the capacity to be happy and have richer relationships. Unhealthily high or low self-esteem levels can be both socially and emotionally harmful. If people with inflated self-worth are attacked or challenged, they react in a secure and defensive way. High self-esteem can result in narcissism meaning that the person has difficulty with empathy because has too much love for themselves which makes them arrogant. The word narcissism originated from Narcissus from Greek Mythology. He fell in love with his own reflection. As well as high self-esteem, there is low self-esteem which can result due to many reasons including appearances, mental diseases, security and bullying/peer-pressure. People with low-self esteem find many faults with themselves, whether or not it’s true. They show too muc h eagerness to please and gain other people’s affections and not offend people. They are also envious and jealous of others with traits and possessions they wish to have. They have an air of hostility around them and be irritable without a reason.

Essay on Incorporation of Technology into Modern Education

Incorporation of Technology into Modern Education Education has long been a part of our society. In order to keep society progressing forward, education must also progress forward. Part of this forward progression is the incorporation of technology into modern education. Technology has always been in schools. The development of things like the overhead projector, typewriter, and blackboards have all played key roles in education. However, the pinnacle of technological advances has been the introduction of the computer into the classroom. Since the computer first entered the classroom in the early 1980?s as more than just a tool for school officials, student?s exposure to the ever-changing world of technology has nearly quadrupled.†¦show more content†¦Department of Education, National Center for Educational Statistics, National Assessment of Educational Progress, Almanac: Writing, 1984 to 1996. 1998 It?s this early exposure to computers that could help students gain the technological understanding that maybe essential in the workplace for future success. In order to understand the revolution that technology is creating within education, first it needs to be understood how we got this far.

Now data storage and writing could be combined with images and graphics, and is readily available for school, home, and office use So now you ask, how has this development changed the face of education? The public often has two opinions on how technology has changed education. There are those who feel that education has been changed for the better, and those who feel that technology has made no impact and in the long run is worse for education. Those who feel that technology has had no impact on education hold their beliefs based on many reasons.

The Birth of Rock N’ Roll †a Case of Racial Conflict Free Essays

THE BIRTH OF ROCK n’ ROLL – A CASE OF RACIAL CONFLICT The term rock ‘n’ roll has been traced back as far as the 1920s in black music, but it became an accepted when disc jockey Alan Freed began used it to describe the character of the rhythm and blues he played on his radio program in the mid-‘50s. The term â€Å"Rockin’ and Rollin† were originally used as slang for sex, in black pop music. However, it went on to become the name for a new, salacious musical genre. We will write a custom essay sample on The Birth of Rock N’ Roll – a Case of Racial Conflict or any similar topic only for you Order Now Innovation in audio technology, new instruments, fresh talent, business savvy record producers, and a young population of new consumers created by post-war economic prosperity helped turn â€Å"race music† into â€Å"rock and roll†. The roots of Rock Roll can be traced back to rhythm and blues and country rock. We must note the political context of the rock n’ roll movement before delving deeper into the recesses of the genre. Black people were beginning to identify and assert themselves racially supported by a series of Supreme Court judgments in favour of integration and the Black community in general Rock n’ roll became a symbol of Black empowerment to the Whites, especially to the segregationists who were accustomed to and valued a separation of the races, but were now legally forced to operate against those segregationist values. The resistance to rock n’ roll music, highly enjoyed by young White kids, was a culmination of all the hostility and tension of the Civil Rights movement. There was a certain White resistance to such music in the form of The Ku Klux Klan and other White-supremacist organizations that openly preached the exaggerated consequences of listening to rock n’ roll music. The term â€Å"jungle music† was used to describe the rock n’ roll beat, declaring it would cause the White youth to lose their sense of humanity and dignity while mixing races. This kind of resistance to the rock n’ roll movement often came to physical assaults on Black performers. There have been reports of assaults such as the one on Nat King Cole, arguably one of the most docile African American performers of the time. While performing at a Whites-only venue, a mob rushed the stage and beat him. Nat King Cole not only suffered the bruising from the White audience who ambushed him, but also a tongue lashing from Black activists who reprimanded him for not demanding integrated venues. The conflicts of rock n’ roll music are direct reflections of both the institutional resistances of Whites to integration and the widespread exploitations of Blacks across the country in many industries. The post-war economic boom ushered in a new era in radio broadcasting. With greater competition, national radio networks gave way to a horde of new independent, locally based stations hosting a variety of entertainment programs. White radio producers would hide Black performers from White audiences. They would often choose a tune with potential from a Black artist, and have a White singer perform the song without the provocative dancing or emotive moaning of the original version. This proved to be a multiple win for the Whites as the Black artist would be kept away from the spotlight, the White producer was making the money, and White kids were idolizing the White singer. It is widely believed that iconic artists like Pat Boone, Elvis and Georgia Gibbs began by assisting in the exploitation of Black artists who were replaced by more-polished, White impersonators. Many observers suggest that rock n’ roll would never have been so controversial had it not been for the sexual revolutions and conflicts going on throughout the mid 1900s. The rock n’ roll revolution coincided with the institutional revolution of acknowledging youth sex. Rock n’ roll music often ended up portraying sex as a new, fun activity, something that normally happens when young people fall in love. The older generations were quite averse to such music and used many tactics to resist the trend. Magazine campaigning became very popular among the older generations; parental guides and â€Å"girl talks† were printed to show that people still valued pre-marital abstinence. The situation eventually escalated into full censorship, until disc jockeys and music hall owners refused to play Black records in general. There were petitions and requests for radio stations to not play sexually-explicit lyrics, but the response was relatively weak. The truth is that the White artists, who impersonated the Blacks, saved the movement. They cleaned up the sound and look of rock n’ roll, until White parents would accept it. Parents did not want their sons and daughters listening to wild rocker Little Richard Penniman, but would let them listen to Pat Boone. Soon, White faces like Elvis Presley and Jerry Lewis were reintroducing the sexuality of rock n’ roll music and launched it into mainstream legend. Black popular music—everything from jazz and blues to boogie-woogie and rhythm and blues—stood at odds to the white pop songs and artists that epitomized post-world war conservatism. By comparison, rock n’ roll was raunchy, unrestrained, rowdy, and even evolutionary. That which was categorized by the record industry as â€Å"race music† stood as a powerful cultural alternative to the tight-lipped, conformist values. Black Rock n’ Roll music also reflected major social and cultural changes brought on by post war urbanization, including youthful rebellion. By contrast, wh ite pop music had ignored or watered down these transformations. American youth, inspired by nonconformist icons like James Dean, Marlon Brando, and Natalie Wood, naturally gravitated toward the more edgy black tunes which they felt spoke of their frustrations. These young whites made black music their own by learning the dances, memorizing the slang, and copying the cool swagger of African-American boogie-woogie and rhythm and blues artists. They claimed as their own a genre scorned by most whites born before World War II. Thus, Rock n’ Roll was indeed reflective of the Civil Rights movement. It stirred up a whole generation and shows that a culture conflict usually always has a deeper context to be found. How to cite The Birth of Rock N’ Roll – a Case of Racial Conflict, Essay examples

Wireless Sensor Networks Introduction to CDMA

Question: Discuss about the Wireless Sensor Networks for Introduction to CDMA. Answer: What does an amplifier do and why is one needed in a radio system? An amplifier is mainly an electronic component that can boost an electric current or some signals. Amplifiers are primarily used to amplify signals like let just say someone has hearing aid, the machine takes the sound all around the surroundings and then just increases its strength; this process is called amplification. Amplifiers are just known to amplify weak signals too strong signals. Amplifiers are the best option to regain a particular signal that is lost during the transmission (Freeman, 2007). It catches the signal, regenerates the actual signal and sends it to the receiver. Use of amplifiers is the most common thing in the case of transmission. Modulation-Demodulation, Coder-Decoder use amplification in each and every occasion. As a whole, it can be considered that amplifiers are mainly there to regenerate the lost signal so that efficiency of the sender and satisfactory level of the receiver are maintained. An amplifier can be used in radio systems very efficiently. It is mainly the modified amplifier that generally magnifies the high-frequency signals. It is used in radio system. The frequency in which the large number of improvement occurs in a particular radio frequency (known as RF) amplifiers are made of inconstant by frequently changing the capacitance as well as the inductance of a, particularly tuned circuit (Hussain, 2005). The request of amplification is very typical like firstly it receives the signal from the antenna earlier it is assorted with the local noise signals. The primary detector of the radio receiver receives the signal at first. The amplifier which is followed by the detector is a particular type of amplifier called the immediate frequency amplifier. The primary justification of rf amplifier can be done through its tuning ability over the assigned input frequencies. The shunt capacitance is mainly causes a problem for the improvement of a resistance-capacitance j oined amplifier. Then it turns out to be the portion of the tuning capacitance in the amplifier. In this way, the high gain at radio frequency is permitted. The above description tells us the clear picture about the use of an amplifier in the radio system. The range of frequency of a radio system is mainly restricted and after receiving the signal from the antenna, many noisy signals can be attached to the primary signal that can cause a problem. Then the rf amplifier and if amplifier comes into play (Feucht, 2010). The detector also plays a vital role in it. What is the purpose of a mixer? Include a discussion of sidebands in your answer. Mixer A mixer is an electronic device. It is mainly used to combine, changing and routing the volume level. It also combines the dynamic and timbre of several audio signals. For example, Microphone can be used by singers as well as mics can be used in acoustic instruments. For example, mics are used on drums as well as saxophones. The mixer can lead an essential role to transmit signals from electric as well as electronic instruments (Mangeot, 2005). Electric bass, the synthesizer is an example of such electric instruments. Analog and digital signals can be controlled by Mixer from 2010. It depends on the type of the mixer. A combined output signal can be produced by the summation of the modified signals. The signals are broadcasted by the user through a sound reinforcement system. The mixer can be used in several applications. The application includes several recording studios, sound reinforcements system, dance clubs, nightclubs, film production and television. The combined signal of two microphones can be combined by a typical application. The signals are transmitted to an amplifier which controls one pair of signal concurrently (Liu, Zhang and Yang, 2012). In the case of live performance, the signal which transmitted from the mixer goes directly to the amplifier. The amplifier must be plugged into the cabinet of the speaker. There are only two channels are provided in DJ mixer. It mixes two recording player. The mixer can also provide phantom power in capacitor microphones. It also provides pain control for changing the position of sound control. The mixer can also play an essential role for filtering and equalization. It can be the primary purpose of a mixer. It activates the sound engineer who boosts the sound frequency as well as cut the sound frequency to develop the quality of the sound. Mixer mainly uses in the digital processing techniques to attach three different input audio signals into one single output audio signal. It also manipulates every input signal modulation. It also maintains the high and low pass filters in its each audio channel independently. A mixer mainly provides the ability to observe each audio signal channels without providing any master output. A single, equalized and mixed signal can be obtained by the user from three different audio input signals. It provides an important role for mixing two songs as well as combine instrumental tracks together and create a passage of complex music. Sidebands IQ To identify the process for maximizing the information transmission, it is crucial to introduce IQ mixers. It allows user for modulating the in-phase as well as quadrature components of career concurrently (Edlich, 2013). It uses for the multiplexing of two modulating signals. Block Diagram Fig: 1 Sources: IR and SSB Image reject mixer can be used to allow a user to catch a signal in the crowded environment. It is overpowering the adjacent image signal. Image request mixer is also responsible for releasing the requirements of receiver filter. The single sideband mixer is mainly used to allow a user for up converting to a signal; it up-converts the signal into a career while overpowering frequency signal of the similar image (Archer, 2006). It is also responsible for releasing the requirements of the transmission signal. Fig: 2 Sources: Compare and contrast the multiplexing techniques CDMA and FDMA in the area of wireless networking? CDMA CDMA mainly refers to the fact of conversion of analog-to-digital signals. It is mainly done with the help of the spread spectrum technology. In this case, audio input is mostly manipulating into binary elements. It helps the receiver to follow the exact transmitter frequency (Abu-Rgheff, 2007). The CDMA channel normally has a range which is 1.23MHz wide. The Soft handoff scheme is used by CDMA networks that minimize signal fragmentation as a receiver which passes from one to another cell. The perfect mixture of spread spectrum modes as well as digital methods which support additional times as numerous signals per unit bandwidth as the analog modes. The nationwide roaming facility is provided by this technique as CDMA is companionable with the different cellular machineries (Engels and PetreÃÅ' , 2006). CDMA One is known as the original CDMA standards. A transmission speed of up to 14.4 Kbps can be offered by CDMA on its single channel. It can afford a capacity of 115 Kbps in an eight channel form. It is also to be notified that CDMA2000 as well as Wideband CDMA which send data as many times quicker. Working principle of CDMA: Unlike FDMA, CDMA separates calls by codes where each and every particular bit of a discussion is marked with a particular as well as unique code. In this process the system receives a call then it assigns the particular unique code in that specific conversation. Then the data is divided into minor parts as well as tagged with the exclusive code given to that specific conversation of which they are the parts of. After this part, the data is sent through some frequencies which are available to use at any specific time in a particularly mentioned series. At the end of the transmission, the receiver then recollects or regathers the codes to gain the actual message or data or signal. The technique of CDMA is mainly based on the separation of codes. That differs CDMA from FDMA. FDMA FDMA is standing for Frequency division multiple access. It is mainly the channel manipulation method through which multiple admittance protocols are used in a network. A unique allocation or different frequency can be sent to the user by this multiplexing technique (Koo et al., 2002). FDMA is used for wireless and satellite communication. It also co-ordinates the uses among several users. This technique mainly allocates for the wireless cellular phones. Here FDMA technique communicates into 30 channels. Working Principle of FDMA In FDMA, almost maximum users share frequency channel as well as the satellite transponder. But only every user transmits the signal at a single frequency. Every channel can contain digital service as well as voice conversation. It also carries digital data. In AMPS (Advanced Mobile Phone Services), FDMA leads a primary role to give better services. Here every channel can be assigned to one single user at the same time. That is the primary function of FDMA. FDMA is also be used in the TACS (Total Access Communication System). Unlike CDMA, in FDMA all channels are in an idle state when not in use. The bandwidth of the communication channel is comparatively narrow. It is also known as Narrowband system. To spread the symbol time, there is no need of equalization in FDMA. In this technique, analog signals can be most suitable. Also for continuous transmission, there is no need for synchronization. In the case of duplexing, FDMA combined with FDD. It is based on the separation of frequency. References Abu-Rgheff, M. (2007).Introduction to CDMA wireless communications. Amsterdam: Academic.

Child Discipline Essay Example For Students

Child Discipline Essay The discipline of a child must always come from the parents, as society says. Power corrupts, however, and absolute power over another person can corrupt absolutely. Taking advantage of the thinness of the line between discipline and abuse, a parent often doesnt have to answer to anyone if and when they cross that line. In Mary Fishers essay The Broken Chain, Fishers father must deal regularly with punishing and disciplining his daughter. When bad, Fisher would occasionally have to bare her bottom to her father, awaiting punishment. Rex, her father, would then deal out the appropriate number of spankings, usually relative to her age. One evening when Fisher lost her patients, she dropped her baby brother from a highchair onto the floor. The response from her father was immediate and unthinking, smacking her aside the head and sending her across the room. Fisher spent the rest of the night in her room. Fishers mother eventually came to her room and revealed some details about her fathers past. Fishers father and his brothers were heavily abused as a child, and only after becoming larger than their father did the abuse stop. Rex always feared being bound to his father through that abusive nature. Before that night, he had never struck out in anger against another person. Never confronting his past, Marys father finally forces himself to look at his life. With his troubled past uncovered, Rex can begin to deal with his issues and allow his inner wounds to start healing. Rex no longer feared the chains of violence that bound his father. Fisher herself describes Rexs spankings as heavy, dutiful slaps. Dutiful gives the impression that Fisher knows that Rex is only doing his job, and in the end it is in Fishers best interests. When rage took over, however, Rex didnt give any thought to what was best for Fisher, and this is where abuse begins.
