Throughout history there has been dozens of civil rights activists, many who are still read about even today. Two of the most notable activists are W.E.B Du Bois and Booker T. Washington, both whom were the voices for African Americans. Although, both great leaders, they did not always agree completely, often butting heads over the others ideals. Booker T. Washington was a young African American man living in the south, during the civil rights era. Washington, being the last generation of slaves, became the voice of past slaves and the African American people. W.E.B Du Bois, although conflicting with Washington often, spoke of him in the highest regard. In his article Ã¢â¬Å"Of Mr. Booker T. Washington and OthersÃ¢â¬ Du Bois speaks ofÃ¢â¬ ¦show more contentÃ¢â¬ ¦ever knew. Du Bois explains how although this is ok for a southern man like Washington to conform, when making the transition from the south to the north times are different. He challenges how Washington should not have went a long preaching to the north when he did not completely understand what being in the north entailed. He describes how WashingtonÃ¢â¬â¢s educational and consumerism approach is intelligent for someone like Washington, being an educator, but not the best solution for the African American population. From Du Bois perspective the only reason Washington came into power so quickly, was because it has been shown through history when a leader is needed, a leader will be presented. African Americans have lived a life of powerlessness and when Washington, a well-educated man, presented himself to them, they took the opportunity to be guided. In Du Bois article, he breaks down the transition from slave hood to freedom. He goes into depth about how slaves lived a life of submission and for them to be free meant they had to take the opportunity to be free. Which is opposing WashingtonÃ¢â¬â¢s proposal to conform to the white standard, because that is what African Americans have been doing for centuries. An example of this continuous oppression is referenced by Du Bois.

Case Study Summary Music Television Networks (MTVN) had developed over the years a reputation for its ability to provide localized content without diluting what MTV stood for. What MTV wanted to do now, was enter the Arabian/Middle Eastern markets where everything is different. However, the company faced the most challenging test in late 2007 with its launch of MTV Arabia in the Middle East, which some experts considered as the biggest launch in the channel s history. While the market in the Middle East offered MTVN huge opportunities due to its huge youth populace, MTV s controversial content that was known for angering religious, political, and conservative communities, could easily backfire in the conservative environment prevalentÃ¢â¬ ¦show more contentÃ¢â¬ ¦Ã¢â¬ ¢ The channel was targeted at the countries of Egypt, Saudi Arabia, United Arab Emirates, Lebanon, Bahrain, Jordan, Kuwait, Oman, Qatar, Yemen, Palestine and Syria. The Arab culture, unlike American culture though is broadly conservative as per Islam, the degree of conservatism varies across these twelve countries. Saudi Arabia is the most conservative and perhaps United Arab Emirates is the least conservative in this group. It can be portrayed very early that the lifestyles and languages are extremely different in these countries, compared to the American way of life. However, with over half of the population below 25 years old who have an awareness and interest in the American culture, the channel felt that the Arab market had good potential for its offerings. In addition to the complexities of setting up a new business in the Arab world, some of the culture specific challenges faced were very in depth. For instance, MTV had to have the right mix of content for the Arabian audience which should be international quality music and at the same time be culturally sensitive. It cannot have the explicit and provocative content normally made available to American audiences. Additionally, music videos and live shows have to be properly edited and produced to make certain that they are in alignment with the cultural ethos of the Arab world.

The accuracy and validity of autobiographical memory among individuals who have experienced childhood sexual abuse (CSA) has been questioned since these experiences are highly emotional and traumatic. Some individuals may believe that recovered memories through the use of therapy or spontaneously may be recalled in an effort to gain money in a court case or seek revenge against an individual. In order to examine whether this statement of a disbelief in the accounts of individualÃ¢â¬â¢s experience with CSA is valid, the components of autobiographical memory, the specificity in the recall of autobiographical memory among repressed, recovered and continuous memories for individuals having experienced CSA, as well as the cognitive aspect of autobiographical memory will be presented. Autobiographical memory is divided into two components, which are personal semantic information and personal episodic information (Holland Kensinger, 2010). Personal semantic information is information that you know about yourself such as your name and birthplace. While personal episodic information is information about a specific event in your life such as the first time you learned how to ride a bike. In relation to CSA, personal semantic information would be the victim knowing the name of the perpetrator of the crime. As for personal episodic information, it would be remembering the experience of having been a victim of CSA as a whole. Personal episodic information entails further processes such as

Video is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion. Raw video can be regarded as being a series of single images. There are typically 25, 30 or 50 frames per second. There are two types of video recording systems/formats. Also, the term video (video meaning I see, from the Latin verb videre) commonly refers to several storage formats for moving pictures. These are Analog Video and Digital Video. The world we sense is full of analog signal; electrical sensors such as transducers, thermocouples, microphones convert the medium they sense into electrical signals. These are usually continuous and still analog. These analog signals must be converted or digitised into discrete digital signals that computer can readily deal with. Special hardware devices called Analog-to-Digital converters perform this task. For playback Digital-to-Analog must perform a converse operation. Analog Video Analog Video is usually captured by a video camera and then digitised. We will write a custom essay sample on Multimedia Systems or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Digital Video Digital video is a type of video recording system that works by using a digital rather than an analog video signal. Digital video comprises a series of orthogonal bitmap digital images displayed in rapid succession at a constant rate. In the context of video these images are called frames. We measure the rate at which frames are displayed in frames per second (FPS). Since every frame is an orthogonal bitmap digital image it comprises a raster of pixels. If it has a width of W pixels and a height of H pixels we say that the frame size is WxH. Pixels have only one property, their color. The second half contains only the even-numbered lines. Those halves are referred to individually as fields. Two consecutive fields compose a full frame. If an interlaced video has a frame rate of 15 frames per second the field rate is 30 fields per second. All the properties and formulas discussed here apply equally to interlaced video but one should be careful not to confuse the fields per second with the frames per second. Properties of compressed video The above are accurate for uncompressed video. Because of the relatively high bit rate of uncompressed video, video compression is extensively used. In the case of compressed video each frame requires a small percentage of the original bits. Assuming a compression algorithm that shrinks the input data by a factor of CF, the bit rate and video size would equal to: BR = W * H * CD * FPS / CF VS = BR * T / CF Please note that it is not necessary that all frames are equally compressed by a factor of CF. In practice they are not so CF is the average factor of compression for all the frames taken together. The above equation for the bit rate can be rewritten by combining the compression factor and the color depth like this: BR = W * H * (CD / CF) * FPS The value (CD / CF) represents the average bits per pixel (BPP). As an example, if we have a color depth of 12bits/pixel and an algorithm that compresses at 40x, then BPP equals 0. 3 (12/40). So in the case of compressed video the formula for bit rate is: BR = W * H * BPP * FPS In fact the same formula is valid for uncompressed video because in that case one can assume that the compression factor is 1 and that the average bits per pixel equal the color depth. Bit rate and BPP As is obvious by its definition bit rate is a measure of the rate of information content of the digital video stream. In the case of uncompressed video, bit rate corresponds directly to the quality of the video (remember that bit rate is proportional to every property that affects the video quality). Bit rate is an important property when transmitting video because the transmission link must be capable of supporting that bit rate. Bit rate is also important when dealing with the storage of video because, as shown above, the video size is proportional to the bit rate and the duration. Bit rate of uncompressed video is too high for most practical applications. Video compression is used to greatly reduce the bit rate. BPP is a measure of the efficiency of compression. A true-color video with no compression at all may have a BPP of 24 bits/pixel. Chroma subsampling can reduce the BPP to 16 or 12 bits/pixel. Applying jpeg compression on every frame can reduce the BPP to 8 or even 1 bits/pixel. Applying video compression algorithms like MPEG1, MPEG2 or MPEG4 allows for fractional BPP values. Constant bit rate versus variable bit rate As noted above BPP represents the average bits per pixel. There are compression algorithms that keep the BPP almost constant throughout the entire duration of the video. In this case we also get video output with a constant bit rate (CBR). This CBR video is suitable for real-time, non-buffered, fixed bandwidth video streaming (e. g. in videoconferencing). Noting that not all frames can be compressed at the same level because quality is more severely impacted for scenes of high complexity some algorithms try to constantly adjust the BPP. They keep it high while compressing complex scenes and low for less demanding scenes. This way one gets the best quality at the smallest average bit rate (and the smallest file size accordingly). Of course when using this method the bit rate is variable because it tracks the variations of the BPP. Video can be recorded and transmitted in various physical media: in magnetic tape when recorded as PAL or NTSC or SECAM electric signals by video cameras or in MPEG-4 (Moving Pictures Expert Group-4 format) or DV (Digital Video) digital media, when recorded by digital cameras. PAL, short for Phase Alternate Line, is an analogue television encoding system used in broadcast television systems in large parts of the world such as Europe, Asia, Australia, parts of Africa (Kenya etc) etc. ). NTSC, named for the National Television System Committee, is the analog television system used in most of North America, most countries in South America, Burma, South Korea, Taiwan, Japan, Philippines, and some Pacific island nations and territories. SECAM (Sequentiel couleur a memoire, French for Sequential Color with Memory), is an analog color television system first used in France, Russia, parts of Africa etc. It is, historically, the first European color television standard. There is also 3D-video, digital video in three dimensions apart from 2D-video. Characteristics of video streams Number of frames per second Frame rate, the number of still pictures per unit of time of video, ranges from six or eight frames per second (frame/s) for old mechanical cameras to 120 or more frames per second for new professional cameras. PAL and SECAM standards specify 25 frames/s, while NTSC specifies 29. 97 frame/s. Film is shot at the slower frame rate of 24photograms/s, which complicates slightly the process of transferring a cinematic motion picture to video. The minimum frame rate to achieve the illusion of a moving image is about fifteen frames per second. Interlacing Video can be Interlaced (Interlace is a technique of improving the picture quality of a video signal without consuming extra bandwidth. Interlaced video was designed for display on CRT televisions. ) or Progressive(Progressive or non-interlaced scanning is a method for displaying, storing or transmitting moving images in which all the lines of each frame are drawn in sequence. ). Interlacing was invented as a way to achieve good visual quality within the limitations of a narrow bandwidth. The horizontal scan lines of each interlaced frame are numbered consecutively and partitioned into two fields: the odd field (upper field) consisting of the odd-numbered lines and the even field (lower field) consisting of the even-numbered lines. NTSC, PAL and SECAM are interlaced formats. Abbreviated video resolution specifications often include an i to indicate interlacing. For example, PAL video format is often specified as 576i50, where 576 indicates the vertical line resolution, i indicate interlacing, and 50 indicate 50 fields (half-frames) per second. In progressive scan systems, each refresh period updates all of the scan lines. The result is a higher spatial resolution and a lack of various artifacts that can make parts of a stationary picture appear to be moving or flashing. A procedure known as deinterlacing can be used for converting an interlaced stream, such as analog, DVD, or satellite, to be processed by progressive scan devices, such as TFT (Thin Fluorescent Tube) TV-sets, projectors, and plasma panels. Deinterlacing cannot, however, produce a video quality that is equivalent to true progressive scan source material. Display resolution The size of a video image is measured in pixels for digital video, or horizontal scan lines and vertical lines of resolution for analog video. In the digital domain (e. g. DVD) standard-definition television (SDTV) is specified as 720/704/640? 480i60 for NTSC and 768/720? 576i50 for PAL or SECAM resolution. However in the analog domain, the number of visible scanlines remains constant (486 NTSC/576 PAL) while the horizontal measurement varies with the quality of the signal: approximately 320 pixels per scanline for VCR quality, 400 pixels for TV broadcasts, and 720 pixels for DVD sources. Aspect ratio is preserved because of non-square pixels. New high-definition televisions (HDTV) are capable of resolutions up to 1920? 1080p60, i. e. 1920 pixels per scan line by 1080 scan lines, progressive, at 60 frames per second. Video resolution for 3D-video is measured in voxels (volume picture element, representing a value in three dimensional spaces). For example 512? 512? 512 voxels resolution, now used for simple 3D-video, can be displayed even on some PDAs. Aspect ratio Aspect ratio describes the dimensions of video screens and video picture elements. All popular video formats are rectilinear, and so can be described by a ratio between width and height. The screen aspect ratio of a traditional television screen is 4:3, or about 1. 33:1. High definition televisions use an aspect ratio of 16:9, or about 1. 78:1. The aspect ratio of a full 35Ã mm film frame with soundtrack (also known as the Academy ratio) is 1. 375:1. Ratios where the height is taller than the width are uncommon in general everyday use, but do have application in computer systems where the screen may be better suited for a vertical layout. The most common tall aspect ratio of 3:4 is referred to as portrait mode and is created by physically rotating the display device 90 degrees from the normal position. Other tall aspect ratios such as 9:16 are technically possible but rarely used. Pixels on computer monitors are usually square, but pixels used in digital video often have non-square aspect ratios, such as those used in the PAL and NTSC variants of the CCIR (Consultative Committee on International Radio) 601 digital video standards, and the corresponding anamorphic widescreen formats. Therefore, an NTSC DV image which is 720 pixels by 480 pixels is displayed with the aspect ratio of 4:3 (which is the traditional television standard) if the pixels are thin and displayed with the aspect ratio of 16:9 (which is the anamorphic widescreen format) if the pixels are fat. EDITING VIDEO Editing videos typically involves: removing frames, inserting frames, mixing audio with video, giving special effects on video, adding transitions between two clips, superimposing clips and adjusting transparency, applying filters to the clips, and adjusting volume of audio. We can also fade-in and fade-out the audio in various frames. In order to edit videos, it is helpful to understand the concept of timecode. Timecode, a unit of measurement, can be used as an address of a frame, and it can also be used as a unit to measure the duration of a video clip. The timecode used by SMPTE (Society of Motion Picture and Television Engineers) has become a standard and is in the form Hrs: mins: secs: frames. For example, a clip with duration of 00:02:31:15 plays for 2 Minutes, 31 seconds, and 15 frames. At the rate of 30 frames per second (fps), 15 frames will take half a second (0. seconds) to play. This clip will, therefore, play for 2 minutes and 31. 5 seconds. Thus, a fraction of a second is measured in frames, and to know the time with millisecond accuracy, we need to know the fps of the clip. The same code can be used to address a particular frame. For example, 00:1:30:12 is the address of the 12th frame that comes after 1 minute and 30 seconds of playing a clip. There are many software packages which support such editing. Some that are well known among these are Adobe Premiere, Adobe After Effects, Strata Avid Video, Asymmetric M Digital Video.

Good Fats vs Bad Fats Essays Good Fats vs Bad Fats Essay Good Fats vs Bad Fats Essay Joe Haywood English 1101 M, W- 6pm 27July11 Good Fats vs. Bad Fats In todayÃ¢â¬â¢s society, eating healthy is bigger then ever with everyone trying to achieve his or her dream body. Any fitness or diet professional will tell you that the biggest way to alter your appearance is by changing your eating habits. One area of the diet that seems to confuse people when it comes to eating healthy is fat. For years fat in the diet is something that people always try to avoid and have always been associated with rising cholesterol levels, causing cardiac diseases and obesity. For years doctors and nutritionist have preached the benefits of a low fat diet. Although these disease can be linked to a high intake of fat in the diet, what a lot of people donÃ¢â¬â¢t realize is that fat is need in the body and is very beneficial when consumed properly. Fat is also use to absorb nutrients, improve heart and brain health, provide cell maintenance, lower the risk of cancer and other chronic diseases. Keys to gaining the benefits of fats are being able to decipher the difference between unsaturated Ã¢â¬Å"good fatsÃ¢â¬ and saturated Ã¢â¬Å"bad fatsÃ¢â¬ in you diet but at the same time realizing that both are needed in the diet. : Good fats are also known as unsaturated, monounsaturated and polyunsaturated. Ã¢â¬ These fats can be found in fatty fish, peanut butter, almond butter, soy milk, nuts, avocados, olives and oils that are liquid at room temperature. Fish oil, omega 3s and omega 6s are good fats that can also be consumed in supplement forms. (Tsang 2004) The benefits of good fats are they are known to decrease LDL or Ã¢â¬Å"bad cholesterolÃ¢â¬ level and raise HDL Ã¢â¬Å"good cholesterol, reduce risk of heart disease, high blood pressure and cancer, improve joint health and improve emotional well being. Bad fats also go by the names of saturated and trans fat. Saturated fat can be found in high amounts in animal products, whole dairy product, eggs and lard. These fats are solid at room temperature. Saturated fats raise LDL (bad) cholesterol levels and can lead to higher risk of chronic cardiac disease. Trans fats raise LDL (bad) cholesterol levels and lower HDL (good) cholesterol levels. Trans fats are used to extend the shelf life of processed foods. They can be found in cookies, cakes, French fries, donuts and any items that contain hydronated oils. Trans fat should be avoided at all cost. These fats are the leading cause of cardiac diseases and raise the risk of heart attacks and strokes. These fats are considered to be so bad that since 2006 all food manufactures are required to list their trans fats content on their food labels. (Mann, 2011) Intake of fats has been separated into the two categories of good and bad. To maintain a healthy living both need to be included in your diet. Fat should make up 20-35 percent of your caloric intake. Less then 10 percent should come form saturated fats with the rest coming from unsaturated fats. Trans fat should be avoided at all cost. Following these recommendations will lead to many health benefits. Mann, Denise. Trans Fats: The Science and the Risks.
