Mix-tape Phenomenon Essay example -- Music Arts Rap Papers

Mix-tape Phenomenon "This rap game, this rap game / I ain't sellin' my soul for this rap game..." - 50 Cent Just 20 years ago, hip-hop music was thought to be just a simple fad, passing its way through the mainstream of pop music leaving classic dance hall anthems like Kurtis Blow's "Basketball" and Grandmaster Flash and the Furious Five's "White Lines (Don't Do It)" in its wake. But today, hip-hop is a worldwide phenomenon, marking its influence in the world of fashion design (Jay-Z's Roca-Wear and OutKast clothing lines), product marketing (McDonald's and Sprite), and even television shows and movies (Eminem's "8-Mile" and most recently, "Honey," starring Jessica Alba). Through the past two decades, hip-hop has proven the genre could stand the test of time, but lately, purists say hip-hop is on a steady decline, thanks in part to "bubble-gum rap" or "hip-pop" created by artists such as Ja Rule and Nelly. Hip-pop is when an artist focuses on making records that will be accepted in mainstream pop radio and gain massive air-play, but "sells-out" the artist's integrity. One way hip-hop is fi ghting back against the mainstream backlash is the emergence of mix-tapes, albums created by street DJ's featuring exclusive tracks, artist-to-artist disses, and occasionally, unofficial album releases. But before looking into what may be the future of hip-hop music, let's take a trip back in time to South Bronx, New York City, circa 1977. "Let's take it back to the concrete streets / Original beats with real, live emcee's / Playground tactics / No rabbit-in-a-hat tricks / Just that classic rappin' from Jurassic." - Jurassic 5 Hip-hop pioneer DJ Grand Wizard Theodore, then 17 years old, was practicing his craft as usual, when his moth... ...in a positive force in hip-hop music. And now that former street DJ's such as Kay Slay and Whoo Kid have released commercial mix-tape albums that, according to McDonald, have sold on par with huge holiday season releases from Jay-Z, Alicia Keys and the G-Unit, the door for other street DJ's looking to establish a name for themselves has swung wide open. "A lot of times, whether its medicine or mechanics, a lot of people spend their life putting something together and then address it to the public and then sometimes the public might say, "Nah," says Grandmaster Flash of the mix-tape's evolution. "But thank god this thing has continued to grow and may it continue to grow. May there be many Ron G's and many Clue's and many more Brucie B.'s. Let's keep this thing poppin'."

Gender Stereotypes Essay

Gender stereotypes are type of generalized or oversimplified perceptions, impressions, images, or opinions about men and women (Santrock, 2007, p. 177) It is also the presumption that a certain behavior or trait belongs to certain gender and cannot be applied to the other. In short, gender stereotyping can also involve assigning a certain label to a particular gender. One of the most common gender stereotypes are the ones associated with feminine and masculine behaviors. For example, it is common for most people to perceive that males should always be aggressive and tough. In addition, generally, in emotional situations, men are expected to hold their own and not breakdown or cry. It is also a general perception that young males should always strive to be athletic and active in sports and play toys such as guns, cars, and weapons. On the other hand, there are also several female stereotypes. For example, females are generally perceived to be emotional and are the first ones affected during a dramatic situation. In other words, females are expected to be more sensitive than males. Moreover, females are also generally perceived to be always demure and reserved. Furthermore, sexism is the attitude or idea that one gender is less valuable or weaker than the other or that one gender is better and superior than the other (Santrock, 2007, p. 178). It generally has two forms: old-fashioned and modern sexism. Old fashioned sexism is the belief that there should be differential treatment between women and men because women are significantly inferior to men while modern sexism is the rejection of the belief that there is still antagonism and discrimination towards women and their rights (Santrock, 2007, p. 178). One example of old fashioned sexism is when a male employee has a problem of having a female supervisor or boss. On the other hand, an example of modern sexism is when a male lawyer denies that there is discrimination against women even after his law firm rejected a potential lawyer partner simply because she is a woman.

My Experience At The Age Of 12 - 969 Words

At the age of 12, I first hosted a big show at school. Now I still remember clearly that my Chinese teacher praised me highly for my performance on the stage by saying, â€Å"Good job, you can develop yourself in the TV and journalism areas in future.† From then on, I appeared on the stage more often as a host on campus and I began to enjoy it. In 2007, I came to know Yang Lan, a well-known Chinese talk show hostess and journalist on a TV program and I was totally fascinated by her brilliant performance as a bilingual hostess. Just from her career growth experience, I knew what a journalist really does. In high school, my two years’ experience of learning from a veteran broadcaster, professor Wang at Guizhou TV gave me much exposure to the journalism field. When we first met, he asked me, â€Å"Yahan, since you have strong passion for journalism, what do you think of the value of news?† â€Å"Today’s news will be history tomorrow and maybe we cannot find its value now, but it will definitely become the most valuable historical reference,† I replied seriously. It was professor Wang who initiated me into the professional areas of the television and journalism industry and introduced me to the stories of many famous Chinese TV broadcasters and journalists, such as Bai Yansong and Chai Jing. This experience was an important factor in my decision to study Journalism at China Youth University for Political Sciences (CYU).

Influences Of The Anti Establishment Movement - 2443 Words

This investigation will examine the influences of the anti-establishment movement, major events like the sexual revolution and the how media and pop culture influences fashion in the 1960’s. Every decade has a signature look but the real question is how they got that look. To look further into this subject one may need to investigate major happenings. This is what this paper looks into. The greatest influences to fashion in the 1960’s are analyzed in this paper. Each chapter goes into depth on each influence and how it all relates back to fashion. Fashion is one way of self- portrayal and it can define a time period and a person. The important part is to look into the behind the scenes aspect of fashion and the cultural and social integration into the fashion industry. By looking deeper into the subject I have concluded that fashion is influenced by the happenings of a certain time period. Each time period has its own definitive style which is brought out through fashion. It can be concluded that social and cultural influences are the driving force behind fashion and how it is portrayed in each decade.

Cause Prior to the 1997 Asian financial crisis, emerging economies such as Thailand, Indonesia, and South Korea contributed to nearly half of the economies across the world. Emerging economies are markets within countries whose economy is progressing towards become more advanced. Economies in countries such as the United States, Europe, and Japan are considered advanced. Emerging countries progress with increased growth and industrialization. Economic growth also includes collecting some liquidity in local debt and other areas within the financial info structure. Liquidity is assets or securities that can quickly be bought or sold in the market without causing radical change to the asset’s price. Due to the lack of strict accounting standards and security regulations commonly found in advanced markets, emerging markets often do not have the same level of efficiency built into the financial framework as opposed to advanced economies. The markets though usually share common physical infrastructure such as banks, stock exchange, and collective currency. Emerging markets are often sought by investors due to their potential of returns higher than the more stable advanced economies.

Spread Spectrum Communication Systems †Free Samples to Students

Question: Discuss about the Spread Spectrum Communication Systems. Answer: Introduction: Before attempting to pinpoint the reason why spread spectrum transmission is used, there is a need to understand what is spread spectrum. A form of wireless communication, which is spread spectrum. In spread spectrum transmission, the frequency of signal to be transmitted is intentionally varied (Torrieri, 2015). It is done to increase the bandwidth of the signal. Following portion will talk about the reason for the usage of spread spectrum. 1) Cross talk interference is reduced. For systems utilizing spread spectrum, cross talk is greatly reduced because of the processing gain of spread spectrum. Additionally, by the help of digital processing effect of interference associated with suppressed crosstalk can be removed. 2) Voice quality is better for systems using spread spectrum technology. Spread spectrum system is immune towards noise and interferences because of the digital processing nature and processing gain of the spread spectrum. Analog wireless system often experience device induced noise that is static. Spread spectrum technology helps in reducing induced static noises. 3) Systems using spread spectrum technology are less susceptible to multi-path fading. In a spread spectrum system, frequency can be varied and this property leads to less susceptibility towards multi-path fading. 4) The fourth point will clarify about security. A PN sequence is used to modulate signal. Since the nature of PN sequence is pseudo random, the signal is randomized. For the receiver to de-modulate the signal to receive the original one, it needs to have the same pseudo random sequence. Therefore, it is established that systems using spread spectrum technology are more secure than other systems. 5) The fifth point will describe about co existence for spread spectrum. If pseudo random sequences are properly designed, then several spread spectrum systems can co-exist without the fear that it will create interference for other systems. 6) Operating distance is much longer. In t he ISM band where a spread spectrum device is operated it is allowed to have transmission power, which is higher. Operating distance for devices using spread spectrum technology is much longer when compared to an analog device. 7) Spread spectrum signals are much harder to detect. Narrowband transmissions are much less wider than spread spectrum signals. Since the band is much more widespread, low power is required for its transmission. 8) Spread spectrum signals are hard to demodulate. A specific code is required for demodulation of the signal. It is nearly impossible to decipher the signal without knowing the actual code that was used to modulate the signal. This is the reason why deciphering this signal is hard. 9) A spread spectrum signal is harder to jam. Most important property of spread spectrum systems is rejection of interference. Since the system rejects interference, it is harder to jam. This portion will provide a comparison between two methods used for spread spectrum transmission. Frequency hopping and direct sequence of spread spectrum are two most used methods. The way by which data is spread can tell which method was used for spreading the signal. DSSS uses pseudo noise and FHSS uses frequency hopping for modification of the phase of the signal. In frequency hopping, large bandwidth is divided into smaller channels is which data would be fitted in. After this, the signal is sent into a different channel pseudo randomly ("What is frequency-hopping spread spectrum? - Definition from WhatIs.com", 2018). However, there is a particular drawback on using this technique, since only a single channel is used at a given time. Because of this, bandwidth is wasted. DSSS manages to spread the signal by a different manner. Pseudo random noise is introduced to change the phase of the signal (Naden Reiser, 2015). Output closely resembles static noise however during demodulati on the original signal can be extracted if the pseudo random sequence used to modulate the signal is known. A radio system is made up of transmitters and receivers and therefore components will be listed under transmitters and for receivers. Radio transmitters are composed of- Power supply, Oscillator, Modulator, Amplifier and Antenna. Radio receivers are composed of- Antenna, RF amplifier, Tuner, Detector and Audio Amplifier. This section will provide the basic concept of a mixer. Frequency mixer is a type of electrical circuit. Frequency mixers are generally used for creation of new frequencies that helps in the inter connection of two signals. The task of transmitting signal from one frequency range to the other is critical for radio systems (Wada, Sagawa, Makimoto, 2016). Mixers main objective is for identification of difference level and sum at the end of the communication. A mixer is divided into two types- the first one is named active mixers and the second one is named passive mixers. Signal strength can be increased by the use of active mixers that is further composed of active devices. On the other hand, passive mixers are designed with the help of passive devices such as diodes. Output, which is generated by passive mixers, is much lower when compared to the input signal. However, for active mixers the story is little bit different. Because of the nature of active mixers, they are able to gener ate more power. When comparing it is seen that active mixers are less tolerant to overload. Passive mixers are used several cases since they have wider bandwidth. This section will provide the answer to different types of mixers. Generally, there are different types of mixers available. Based on functionalities and user requirements, mixers can be classified into two types. The first type is known as single balanced mixer and the second type is known as double balanced mixer. Single balanced mixers- This mixer is a special type of mixture, which is able to handle any kind of radio frequency or noise. Single balanced mixture is able to manipulate the data when it passes between the LO and because of this it is able to eradicate the noise. Single balanced mixtures needs to provide isolation between RF and LO (Kimishima, 2009). Working of device mixers is based on connection of two single devices at ninety degree or at one eighty degree. Since the structure of single balanced mixer is simple, users are able to get a good grip of the structure at first glance. Simple structure helps to keep the linearity of signal in check and additionally isolation is generated in every port. Double balanced mixer- Double balanced mixer is a type of passive mixer device. Four-diode ring forms the central part of double balanced mixer. LO signal is rejected when the rings does not match up to a level. When compared to single balanced mixers it is seen that double balanced mixers have certain advantages. There is one major advantage for double balanced mixer which is it improves linearity in the system but it generates more noise when compared to the other type of mixer (Salameh, 2017). It generates more noise since it does not support cancellation. For double balanced mixers, output is in the form of differential and this allows for easy removal of non-linearity in the signal. Ring mixer and star mixer are examples of double balanced mixer. It is also seen that double balanced mixer suppresses both RF and LO but single balanced mixer does not do that. Advantages of using single balanced mixer is more but usage of double balanced mixer is more because of its isolation and l inearity properties. Air is the medium for wireless communication. There are no wires or cables required. Information gets transmitted form one point to the other via electromagnetic waves. Some of the advanced wireless technologies are Li-Fi, Bluetooth and ZigBee. This paragraph will mention some key points about those advanced technologies. Li-Fi uses visible light communication system and it claims to be much faster than the standard Wi-Fi (Karthika Balakrishnan, 2015). As simple as it may sound Li-Fi can use household LED bulbs for data transfer and speeds can be up to 224 Gigabytes per second. Since Li-Fi uses visible light communication systems, it means it include photo detector for receiving light signals. The light signals are then processed by a signal-processing element for conversion of data into another form for transmission. Zigbee communication is a product of Zigbee alliance. The system is specially built for sensor and control networks. It follows IEEE 802.15.4 standard. Data transfer r ates are slower than standard Wi-Fi however cost incurred for a Zigbee system is much less than a Wi-Fi. Zigbee consists of a mesh network and it is used for controlling and monitoring purposes (Gomaa et al., 2014). Bluetooth is a wireless technology, which is used by hand held digital devices for connecting with one another. Antenna are of various types but the dominant ones are horn antenna, parabolic reflector antenna, helical antenna, slot antenna, dielectric antenna, micro strip patch antenna, phased array antenna, dipole antenna and YAGI antenna. Horn antenna is used in satellite communication. It works efficiently with parabolic reflector as evident from dish antennas. Parabolic reflector antenna is coupled with horn antenna and used. It is made up of screen mesh or metal. The next portion will talk about some important points via a power point slide. References: Single balanced mixer vs double balanced mixer difference.
