Psychoactive Drugs - 1914 Words

Psychoactive Drugs are chemical substances that alter behavior, mood, perception, or mental functioning. Through the consumption of substances many cultures have found ways to alter consciousness. Psychoactive substances apply their effects by transforming biochemical or physiological processes in the brain. The message system of nerve cells, or neurons, relies on both electrical and chemical transmission. Neurons rarely touch each other; there is a microscopic gap between one neuron and the next, called the synapse. When a neuron fires, it releases chemicals called neurotransmitters into the synapse. Psychoactive drugs act by altering neurotransmitter function, they bind to the site of the firing neuron and inhibit this process so the†¦show more content†¦People who take these drugs are also faced who psychological effects such as a sense of distance and estrangement, depression, anxiety, and paranoia, violent behavior, confusion, suspicion, and loss of control, plus flashbacks, and behavior similar to schizophrenic psychosis, in addition to catatonic syndrome which is when a user becomes mute, lethargic, disoriented or makes meaningless repetitive movements.

Computer Aided Instruction - 987 Words

COMPUTER-AIDED INSTRUCTION Douglas N. Arnold I. Introduction Computer-Aided Instruction (CAI), diverse and rapidly expanding spectrum of computer technologies that assist the teaching and learning process. CAI is also known as computer-assisted instruction. Examples of CAI applications include guided drill and practice exercises, computer visualization of complex objects, and computer-facilitated communication between students and teachers. The number of computers in American schools has risen from one for every 125 students in 1981 to one for every nine students in 1996. While the United States leads the world in the number of computers per school student, Western European and Japanese schools are also highly computerized.†¦show more content†¦Student training in the computer technology may be required as well, and this process can distract from the core educational process. Although much effort has been directed at developing CAI systems that are easy to use and incorporate expert knowledge of teaching and learning, such systems are still far from achieving their full potential. IV. History In the mid-1950s and early 1960s a collaboration between educators at Stanford University in California and International Business Machines Corporation (IBM) introduced CAI into select elementary schools. Initially, CAI programs were a linear presentation of information with drill and practice sessions. These early CAI systems were limited by the expense and the difficulty of obtaining, maintaining, and using the computers that were available at that time. Programmed Logic for Automatic Teaching Operations (PLATO) system, another early CAI system initiated at the University of Illinois in the early 1960s and developed by Control Data Corporation, was used for higher learning. It consisted of a mainframe computer that supported up to 1000 terminals for use by individual students. By 1985 over 100 PLATO systems were operating in the United States. From 1978 to 1985 users logged 40 million hours on PLATO systems. PLATO also introduced a communication system between students that was a forerunner of modern electronic mail (messages electronically passed from computer to computer).

The Mississippi Burning Could the FBI have done more Free Essays

Depicted in a 1988 movie and subject of many journals, references, and publications, the Mississippi Burning, otherwise known as the United States vs. Cecil price et. al. We will write a custom essay sample on The Mississippi Burning: Could the FBI have done more? or any similar topic only for you Order Now case, has been one of the most famous trials in the country. Mississippi Burning revolves around the murder of three civil rights activists in Mississippi, 1964. The victims were Michael Schwerner, James Chaney, and Andy Goodman. The three were in Mississippi to visit the bombed Mt. Zion church, one among the series of twenty black churches bombed on Summer, 1964. In this visit, June 21 of that year, the three were arrested and illegally detained by Deputy Sheriff Cecil Price. It was also Price who turned the three over to the Ku Klux Klan, in a scripted â€Å"release† for the three with the KKK. The bodies of the three, beaten and shot, were found in a dam almost two months after on August 4. (Mississippi Burning Trial: A Chronology, n.d.) The Ku Klux Klan Racists, terrorists, anti-Semitists—the Ku Klux Klan (KKK) have been called many names from their conception in the 1800s. The Klan started out as a group promoting white supremacy. From their beginnings, they have used terrorism, intimidation, and cross burning against African Americans. While they were successfully suppressed, the KKK has found itself reincarnated by modern followers in the 1920s. This second KKK was also suppressed, but was revived when the Civil Rights Movement was activated in the 1960s. The 60s found the Ku Klux Klan of Mississippi associated with crimes against the civil rights activists, most especially in favor of the Black people. The Ku Klux Klan were found guilty, in federal records, for the assassination of Medgar Evers in 1963, as well as in the well-known trial against Cecil Price for the KKK murder of Schwerner, Chaney, and Goodman. The series of bombings of black churches were also accounted to the members of the KKK. Cross burnings throughout this period was also rampant. (Mississippi Burning Trial: A Chronology, n.d.) According to The Ku Klux Klan (n.d.), the most prominent KKK movement in the 60s was the White Knights of the Ku Klux Klan, founded by Robert Shelton, who was reported to have heavily employed lynching (mob killing) to discourage black people from voting, in contrary to the Mississippi Summer Project encouraging blacks to vote. Schools, homes and white people supporting the movement have also been victimized by the KKK’s lynching and other forms of intimidation. This acts of intimidation, murder, assassination, manslaughter, and were not â€Å"invented† by the 1960’s KKK of Mississippi. Rather, they are renditions of the original KKK’s acts in the 1800s. The FBI and the 1960’s Racist Violence Behind the successes and failures of the racial discrimination cases in the 1960s, most especially in the South, the Federal Bureau of Investigation (FBI) plays a big role. The same case goes in a much publicized case as that of the Mississippi Burning, which interrelates several different racism cases of burning, murder, and civil rights infringements in Mississippi into one highly sensationalized court proceeding. The FBI, though, uses no special means in investigating racist violence at the time. In fact, FBI has had secrets of its own. Glick (n.d.) asserts that the FBI has its way of infiltrating movements in the 1960s, including black movements. In his text, Glick suggests that the FBI has COINTELPRO or counter intelligence program which uses otherwise illegal means of investigation such as infiltration, deception, and harassment to dissolve movements. The main targets were said to be Black movements. Thus, police racism has been existent. There is no known concrete relation between the COINTELPRO and the Mississippi Burning case, however. Could the FBI have done more? 1960s was a period without the present technology that FBI enjoys. FBI investigators had standard procedures to follow, and there is no concrete evidence that they infringed any of these procedures. The Mississippi Burning case was one that has been trialed by the public before the court. Everybody knew who were guilty. Everybody believed Cecil Price and the KKK were to be convicted. That, then the evidences and witnesses affirmed. Thus, the FBI was sufficient and efficient in this respect. However, there are many other cases racism violence and civil rights violation, most of which were not publicized. The FBI has been passive in dealing with these cases. Police racism existed, and if it were true the COINTELPRO worsened the events. The FBI could have devised a special plan to implement anti-racism violence statutes to support the Civil Rights Movement that was active at that time, as it was no ordinary time. Then, it will be known that the FBI has done enough. References Glick, B. (n.d.) COINTELPRO revisited: spying and disruption.

Opera Love Through The Ages With Maria Fortuna And Nancy Townsend Essay Example For Students

Opera: Love Through The Ages With Maria Fortuna And Nancy Townsend Essay On Friday November 3rd I had the pleasure of attending an evening of Opera titled Love Through the Ages with Maria Fortuna and Nancy Townsend at the Sean OSullivan Theatre. Having never been to an Opera performance I had no idea of what to expect and was looking forward to this new experience. Fortuna was accompanied by multi-faceted pianist Nancy Townsend. These two musicians showed tremendous expertise and were able to keep my attention through the extent of the program. Maria Fortuna is a soprano and she has enjoyed international success with her stunning vocal talent. Fortunas repertoire ranges from the lyric soprano to the dramatic coloratura roles, being performed in front of many large audiences and critics. Fortuna was born in Niagara Falls N.Y and more recently received her Masters of Music which led her to her teaching position at SUNY Fredonia. Nancy Townsend is a pianist, vocal coach, conductor and stage director. She has recently performed in recitals throughout the United States, primarily in the west. As I had no idea of what to expect when entering this concert I went in with an extremely open mind. Even leading up to the intermission I wasnt convinced that I was understanding the structure of opera. However, even with my very limited knowledge of opera I could come to a few conclusions. Fortuna and Townsend evidently worked well together, they were always in sync and fed off of each others talent. As well it seemed as if Fortuna was using an aspect of call and response to enhance her production. Her call would be in the form of a story and she would then answer her call with her singing. The show was slightly disrupted in the first half with a large group of people that had been late for the performance, I couldnt visually see any signs of fault on Fortunas behalf when this occurred. An interesting aspect of Fortunas style was unlike anything I had ever seen before. Fortuna would make stable eye contact with specific sections in the audience, this portrayed the feeling that she was singing for the crowd and not herself. The piece within Fortunas selection in which I enjoyed the most was a classical Spanish song titled La mi sola, Laureola. Within all of the classical Spanish songs love was the overwhelming theme. Within this selection Fortuna used a softer pitch and proceeded all of the way through the scale. Fortuna was able to adapt her voice to fit the style of each song, her narration within the songs taken from Shakespeare sounded as if it were Shakespeare reading to himself. Based on this being my first opera experience I was pleasantly surprised. Fortuna and Townsend entertained us for the extent of the program and proved to this small St. Catherines audience that they were accomplished musicians. Music Essays
