The History and Archaeology of Chauvet Cave

Chauvet Cave (also known as  Chauvet-Pont dArc) is currently the oldest known rock art site in the world, apparently dating to the Aurignacian period in France, about 30,000 to 32,000 years ago. The cave is located in the Pont-dArc Valley of Ardà ¨che, France, at the entrance of the Ardà ¨che gorges between the Cevennes and Rhone valleys. It extends horizontally for nearly 500 meters (~1,650 feet) into the earth and consists of two main rooms separated by a narrow hallway. Paintings at Chauvet Cave Over 420 paintings have been documented in the cave, including numerous realistic animals, human handprints, and abstract dot paintings. The paintings in the front hall are primarily red, created with the liberal applications of red ochre, while the ones in the back hall are mainly black designs, drawn with charcoal. The paintings at Chauvet are highly realistic, which is unusual for this period in Paleolithic rock art. In one famous panel (a little bit is shown above) an entire pride of lions is illustrated, and the feeling of movement and power of the animals is tangible even in photographs of the cave taken in poor light and at low resolution. Archaeological Investigation The preservation in the cave is remarkable. Archaeological material in Chauvet caves deposits includes thousands of animal bones, including the bones of at least 190 cave bears (Ursus spelaeus). The remains of hearths, an ivory spearhead, and a human footprint have all been identified within the caves deposits. Chauvet Cave was discovered in 1994 by Jean-Marie Chauvet; the relatively recent discovery of this remarkably intact cave painting site has allowed researchers to closely control the excavations using modern methods. In addition, the researchers have worked to protect the site and its contents. Since 1996, the site has been under investigation by an international team led by Jean Clottes, combining geology, hydrology, paleontology, and conservation studies; and, since that time, it has been closed to the public, to preserve its fragile beauty. Dating Chauvet The dating of Chauvet cave is based on 46 AMS radiocarbon dates taken on tiny pieces of paint from the walls, conventional radiocarbon dates on human and animal bone, and Uranium/Thorium dates on speleothems (stalagmites). The deep age of the paintings and their realism has led in some circles to a scholarly revision of the notion of paleolithic cave art styles: since radiocarbon dates are a more recent technology than the bulk of cave art studies, codified cave art styles are based on stylistic changes. Using this measure, Chauvets art is closer to Solutrean or Magdalenian in age, at least 10,000 years later than the dates suggest. Paul Pettitt has questioned the dates, arguing that the radiocarbon dates within the cave are earlier than the paintings themselves, which he believes are Gravettian in style and date to no earlier than about 27,000 years ago. Additional radiocarbon dating of the cave bear population continues to support the original date of the cave: the bone dates all fall between 37,000 and 29,000 years old. Further, samples from a nearby cave support the idea that cave bears may have been extinct in the region by 29,000 years ago. That would mean that the paintings, which include cave bears, must be at least 29,000 years old. One possible explanation for the stylistic sophistication of Chauvets paintings is that perhaps there was another entrance to the cave, that allowed later artists access to the cave walls. A study of the geomorphology of the cave vicinity published in 2012 (Sadier and colleagues 2012), argues that the cliff overhanging the cave collapsed repeatedly beginning 29,000 years ago, and sealed the only entrance at least 21,000 years ago. No other cave access point has ever been identified, and given the morphology of the cave, none is likely to be found. These findings do not resolve the Aurignacian/Gravettian debate, although even at 21,000 years of age, Chauvet cave remains the oldest known cave painting site. Werner Herzog and Chauvet Cave In late 2010, film director Werner Herzog presented a documentary film of Chauvet Cave, shot in three-dimensions, at the Toronto film festival. The film, Cave of the Forgotten Dreams, premiered in limited movie houses in the United States on April 29, 2011.

Affirmative Action Essay 34 - 1025 Words

Affirmative Action is any effort taken to expand opportunity for women or racial, ethnic and national origin minorities by using membership in those groups that have been subject to discrimination as a consideration. The Fourteenth Amendment states that no person in the United States shall, on the ground of race, color, or national origin, be excluded from participation in, be denied the benefits of, or be subjected to discrimination under any program or activity receiving Federal financial assistance. As a result, Affirmative action is not consistent with the Fourteenth Amendment. In this essay, I will first discuss the violation of Affirmative Action against the Fourteenth Amendment. Second, how Affirmative Action helps one group of†¦show more content†¦The special admissions programs purports to serve the purpose of: (i) reducing the historic deficit of traditionally disfavored minorities in medical schools and in the medical profession; (ii) countering the effects of societal discrimination; (iii) increase the number of physicians who will practice in communities currently undeserved; and (iv) obtaining the educational benefits that flow from an ethnically diverse student body (266). The reasons for having these special admissions are to increase the number of minorities and to have them represent their community. To some people, they might ague that Affirmative Action gives certain advantages to certain people and it is unfair. Affirmative Action was started when the University first got started. Students that possesses athletic skills, the children of alumni, the powerful, connections with celebrities, and the famous has higher chances of getting in the University over other people (290). Not only that Affirmative Action was unfair during that time, it left out the minorities not giving them equal opportunity to receive the education they deserved. Therefore, Affirmative Action violates the Fourteenth Amendment. Affirmative Action gives p rivileges to certain groups and leaving out certain groups not able to succeed without special protection.

High Crime Neighborhood Free Essays

Living in high-crime neighborhoods has a great impact on how neighbors socialize with each other. It either brings them together to fight against violence or torn them apart because the violence is promoted among other neighbors. Neighborhood environment serves as a source of socialization, mainly for adolescents. We will write a custom essay sample on High Crime Neighborhood or any similar topic only for you Order Now Being exposed to different behavioral models or cultural ideas, disadvantaged neighborhoods are thought to influence how young people make decisions about education, employment and relationships (Hackney, 2011). Adolescents interacting with older people that are unemployed, not going to school and involved in crimes can expose them to cultural models that violate social rules and norms. As mentioned in the article it became â€Å"a street culture that arguments are too often settled only when a body ends up on a slab in the morgue† (Hackney, 2011, p. 3). Cultural values are not respected and instead of having dispute-resolution skills and anger management, violence most likely becomes the way of life and solving problems. Socialization is what allows us to be skilled in the ways of the culture we were born into, however, if violence is what one was born into or grew up into that is what they will learn and do. The very fabric of our community has changed, violence has become acceptable by many due to its fast increasing rate but we have to do better (Hackney, 2011). Numerous crimes in neighborhoods destroy socialization although violence is not taught among cultures it could be acquired by its young members if seen promoted by older adults. During adolescence is when youths are developing and exploring new ways of socializing with older adults and that could be dangerous if they are hanging out with the wrong crowd. Young people are highly influenced by their surroundings and if violence is promoted that is what they will learn as a result. Despite the negative impact of violence in neighborhoods it also brings neighbors to work close together in finding solutions for the problem and making their neighborhoods a safer place for their children to grow up and become decent citizens. In Detroit the murder rate has increased and many innocent people were killed by random violence. Public safety plays a great role in socialization therefore the city developed plan to â€Å"strengthen neighborhoods and improve safety† (Hackney, 2011, p. 3). The police patrols were reinforced and many cases were closed with tips from citizens and strong police work. There were programs to get youths engaged in activities other then hanging out in the streets and involved in criminal acts (Hackney, 2011). Working close with youths and getting them involved in activities that can keep them out of the streets can reverse the effects of early exposure to violence and promote a better way of socializing.

Organizational Behavior Discussion Questions free essay sample

How much of Trader Joes’ success can be attributed to the fact that most larger chain grocery stores do not sell the type of food available at Trader Joe’s? This can partially be attributed to their success. The case study focused more on the staff of Trader Joes and their positive work environment adding to the overall customer service experience that has become as strong element of Trader Joe’s success. The opening of the case study even suggests that most customers can’t complete their shopping list at Trader Joes but still leave the store â€Å"satisfied. † 2. Is pay enough of an incentive to continue at a job you do not enjoy? No, pay is not enough incentive to continue at a job you do not enjoy. Pay is only one factor that works in conjunction with many other factors to determine whether or not a person is motivated enough to continue on at a job that they do not enjoy, or even at a job that they do enjoy. We will write a custom essay sample on Organizational Behavior Discussion Questions or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Motivation is a key element in job satisfaction. Without the motivating stimulus of hygiene factors other than salary, or a combination of other motivators there would be very little incentive to continue on at a job a person does not enjoy. . Trader Joe’s promotes entirely from within the organization. This means that if you are a good, dedicated worker, you can rise up within the company. Do you feel employees would be as dedicated to the company if this were not the case? Would high pay be enough to keep employees? What if the company only promoted from within but pay were not as good? Internal promotion is definitely a motivating factor within any business. The potential for advancement is a key motivating factor. Working for a company that exclusively promotes from within creates dedication and loyalty among workers at every level within the organization. No, I do not think that high pay would be enough to keep employees. Without promotion and increased responsibilities the tendency for employees to become bored and disenfranchised with a job position increases. If the company only promoted from within but the pay were not as good, there would be less motivation but as long as the promotions came with increased pay the motivation/dedication/loyalty would still be there but at a much less significant level.
