Effects Of Substance Dependence On A Person s Brain

Nearly everyone knows someone who is dependent upon drugs or alcohol. Substance dependence is an issue, with lifetime alcohol dependence from 2001-2002 in the United States alone being 12.5%, and lifetime drug dependence on drugs being 2.6%. (Fleury, Grenier, Bamvita, Perreault, and Caron 204). Risk for substance dependence varies from one person to another; there are so many factors that can influence it, including just personality and certain attitudes people have. The psychology of a person’s brain is so complex that it would be impossible to determine every single thing that affects a person’s risk for substance dependence. There are some factors, however, that can be studied and measured - and studies have been done on those factors†¦show more content†¦6). These studies show that although not everyone with a family history of substance dependence becomes an addict themselves, it does put them at a significantly greater risk of developing a dependence upon any type of substance they may abuse in their lifetime. â€Å"For the individual with a history of substance dependence in his or her family, even occasional or sporadic abuse should be viewed with more concern that if family substance dependence were not present† (Margolis and Zweben 67). Those with parents and grandparents that have had a substance addiction should be extra cautious when using drugs and alcohol, because it can affect them very differently. â€Å"Just trying it once† could turn into a lifetime reliance upon the substance. The biology of this is not fully understood though one hypothesis is that it has to do with having a fewer number of dopamine receptors in the brain, meaning they might not be absorbing as much dopamine as normal people do (Casey, Benkelfat, Cherkasova, Baker, Dagher, and Leyton 23). This may cause a desire to increase the amount of dopamine in the brain through certain types

John Stuart Mill, Berlin, And Sartre - 2059 Words

Name Professor Course Date Positive and Negative Freedom: According to Augustine, Mill, Berlin, and Sartre As one of the most important concepts in philosophy, freedom always attracted the attention of the thinkers. Such outstanding philosophers as Saint Augustine, John Stuart Mill, Jean-Paul Sartre, and Isaiah Berlin provide valuable responses to the problem of freedom, which are still actual. For instance, Isaiah Berlin can be considered the true ideologist of dialectic of freedom, dividing this issue into positive and negative one. According to Isaiah Berlin, positive and negative freedom are closely connected with social and political development of human civilization. Precisely the way people evaluate and define their freedom influences political and social regime, which can develop in such society. Using the brilliant examples from the history of philosophical thought, Berlin provides the direct instances of negative and positive freedom existence. Each type of freedom premises a separate way of living, social structure, and role of individuality. Defining negative and positive freedom as almost absolutely different concepts, Berlin makes the emphasis that both determine personal activity. Negative freedom is freedom from other people interference. As the philosopher mentions, negative freedom answers the question â€Å"What is the area within which the subject – a person or group of persons – is or should be left to do or be what he is able to do or be, without

There are a number of environmental factors, related mostly to climate, soils and health, resisting easy developmental solutions. Rainfall reliability is closely connected to rainfall quantity. The rainfall in the equatorial heart is very plentiful and reliable. However, there is much less rainfall towards the outer edges of the rain belt. Periodic and unpredictable droughts are a characteristic feature of these border zones. There are three climatic zones in Tropical Africa: 1. a region of persistent rain at and near the Equator, 2. a region on each side of this of summer rain and winter drought, and 3. a region at the northern and southern edges afflicted by drought. All the climates listed in the previous paragraph are modified in the eastern parts of Tropical Africa by the mountains and monsoons. The soils of Tropical Africa pose another problem. They are unlike the soils of temperate areas. Soils are largely products of their climates, and tropical soils are different from temperate soils because the climate is different. Because of the great heat of the tropics tends to bake the soils, while on the other hand, the rainfall leaches them. The combined heat and moisture tend to produce very deep soils because the surface rock is rapidly broken down by chemical weathering. All this causes the foods rate of growth to slow down or maybe even stop and as a result food production wont even come close in catching up to the rate of population increase; therefore starvation and hunger is present. In the process of a flood and drought, the roots of trees are shallow and virtually no nutrients are obtained from the soil. The vegetation survives on its own humus waste, which is plentiful. If the vegetation is cleared, then the source of humus is removed and the natural infertility of the soils becomes obvious. As being another factor, this will cause the soil to produce wasteful and useless products which in turn will decrease the production. To conclude this essay, the climates in Tropical Africa take a big role as being factors that could endanger or destroy the process of plantation. On the other hand, it could also bring good fortune if climatic regions are fairly good. .

Internet Addiction Cause and Effect Essay Example

Internet Addiction Cause and Effect Essay There has been a big percentage of people spending their time on the internet rather than spending time with their family, or friends. Internet use has been categorized as an actual disorder, and has been termed Internet Addiction because of its similarity to addictions like smoking, drinking, and watching too much TV. There are several reasons and causes why people get addicted to the internet; boredom, loneliness, online TV, social networks, etc. They could be lonely in the way that theyre the only child, or they have no friends due to being home schooled, so they waste their time on the internet. Or they could just be bored; they could be home alone, or it could be raining outside, and they cant go out, so they stay in and surf the web. There are also a lot of social networks online like chat rooms, Facebook, Twitter, MSN, and more. People enter social networks to meet new people, and get into virtual online relationships. Entering social networks can also relate to loneliness sometimes. Spending too much time on the internet can affect you very much. It can interfere with your social life, the addiction can lead to the inability to communicate in the real world, and your family bonding. You could have mixed feelings of guilt while at the computer, and it can also distract you from your work/school related work.

Or they could talk to their mothers, or guardians about it, or maybe get a therapist for some help, and try their best to think of all of the effects that could happen to them, and try to stop.

Narrative in Its a Mad, Mad, Mad, Mad World Essay Example

Narrative in Its a Mad, Mad, Mad, Mad World Essay Example Narrative in Its a Mad, Mad, Mad, Mad World Essay Narrative in Its a Mad, Mad, Mad, Mad World Essay Essay Topic: Hilarious Narrative Its a Mad, Mad, Mad, Mad World is an American motion picture directed by Stanley Kramer about the madcap pursuit of $350,000 of stolen cash by a diverse and colourful group of strangers. Even before its release in 1963 it was well established as comedy caper, with a huge ensemble cast of some of the eras finest comedians and comic actors. Due to the changes made in cinema over the last four decades a modern day audience may not understand many of the verbal-jokes, and yet it is obvious through many of the visual-gags that this film played on many comedic techniques, as well as influencing other movies to this day, such a Rat Race, and most likely any modern day caper one can think of. There are three ways to categorize film genres; setting, mood, and format. The films location is defined as the setting; the emotional charge carried throughout the film is known as its mood; the film may also have been shot using particular equipment or presented in a specific manner, or format. However, there is much controversy as to whether film genre identifies merely the general overtone of the film or defines the films style. Some have argued that genre needs to be distinguished from film style. A films style concerns the choices made about cinematography, editing, and sound, and a particular style can be applied to any genre. Whereas film genres identify the manifest content of film, film styles identify the manner by which any given films genre(s) is/are rendered for the screen. Style may be determined by plot structure, scenic design, lighting, cinematography, acting, and other intentional artistic components of the finished film product. Others argue that this distinction is too simplistic, since some genres are primarily recognizable by their styles. Many historians debate whether film noir truly is a genre rather than a style of film-making often emulated in the periods heyday. The opening credits of the movie are animated, which was not uncommon for the period in which it was made, especially for comedy movies. This establishes the films genre before an actor has even crossed the screen, as it relies on the audiences previous knowledge of what might be expected from such a film with an animated opening. The animation is essentially a visual representation of the title, as it shows a globe being distorted and manipulated in various ways which mirror certain events of the movie. This animation is actually a 3 minute round up of the movie, as it displays key events in chronological order and gives the audience a sneak preview of some of the hilarity that will ensue come the start of the movie. As well as the small tidbits of prophetic animation, absurdist humour is also something used throughout this movie; present from the opening credits, and continued into the very narrative of the film. This surrealism is carried over to cinematographical, performance and editing aspects of the movie. This can be described as form-imitating-meaning, in the sense that the movies bizarre premise, of four complete strangers looking for the buried three-hundred and fifty gees of a crazed old man they find dying near the road, is reflected in the canted camera angles, the alternating of fast and slow shot changes and the manner in which the four men speak. This form of outlandish and slightly eccentric comedy was common in the 1960s, and was copied relentlessly with movies such as Help! This queer manner of presenting a movie proved popular with audiences, as it lent itself to heightening the humour present in the more conventional gags of 60s slapstick comedy. Contradictions are frequently used throughout this film, both verbal and visual, and are integral to the overall narrative of the piece, as they reflect the madness the title is referring to, as well as adding to the absurd and illogical atmosphere. Lines such as I am a liar and The only thing you are sure of is that nothing is sure are frequently used in this movie, marking the instances where deception and dishonesty occur. This adds to the comedy on numerous levels, as no character within the movies immediately catches on to the betrayal at hand when such a contradictory line is said, despite it being made painfully obvious the audience. This form of humour, where a character misses or misunderstands a situation, and ends up in some form of hilarious predicament is a staple mark of slapstick comedy caper m ovies, going hand in hand with the humour associated with a characters ignorance. One must remember the era of film production this was created in, as many of the jokes used in this movie are now considered to be clichà ¯Ã‚ ¿Ã‚ ½, and act almost as stereotypes for a comedy movie. However, at the time humour like this was considered to be highly sophisticated, and often reflected the comic-styling of whom ever was portraying a certain character The film opens on a stretch of curved, winding road somewhere in the Southern California desert. The camera follows the progress of a black car as it haphazardly weaves in between the truck and three cars that are driving ahead of him, as he does this car horns and loud, screeching tires can be heard. This gives the impression that the occupant of the black car has little regard for other drivers, and is either driving at breakneck speed to get somewhere soon, or he is being chased. This immediately sets the tone for the rest of the movie, starting as they mean to go on, as it were. This opening shot establishes the movie to have a theme of fast, dangerous car chases with highly comical consequences. The shot cuts to one inside the black car, shot from the backseat, so only the back of the driver can be seen; his rigid stance, with his elbows sticking out and his knuckles white over the driving wheel, coupled with his continuous honking of his horn are very telling to the viewer rega rding what this character is like and solidifies the previous assumption that he is in fact running away from something. The very fact that the camera is only focusing on the black car and its occupant tells the audience that he is an important character to the plot. Following this, we see the black car and its driver veer off the road and over a small cliff. At this point many techniques which are more commonly associated with action films are utilized, such as rapid zoom in, slow motion and viewing the car from multiple angles as it flies off the road. It can be easily argued that this is an example of satire, as the techniques used seem to be highly exaggerated; with the slow motion descent of the car being incredibly lengthy, and changing shot angle and perspective no less than 15 times. Satire is something common in all forms of comedy, and generates response in a movie as it allows a viewer to relate what theyve just seen to the original format; these mental comparisons expand the sense of surrealism already present in the movie, and show how important that sense of strangeness is vital to the movie. Perhaps this movies most obvious comic device is the use of visual metaphors; when the man in the black car is dying; with his last breath he quite literally kicks the bucket. This technique is used over and over in the film, using physical slapstick comedy to provide an unspoken narrative which is easily understood and greatly enjoyed by the audience. Overall, I believe this movie uses its style to effortlessly convey its meaning and narrative. However, I believe it would be unfair to say that this movie used generic genre conventions, as there were none at the time of its creation. If anything, this movie started certain generic genre traits, and influences many films even to this day.
