Quebrada Jaguay - Terminal Pleistocene Archaeology

Quebrada Jaguay (designated QJ-280 by its excavator) is a multi-component archaeological site, located on an  alluvial terrace within the coastal desert of southern Peru, on the north bank an ephemeral stream near the town of Camanà ¡. At the time of its earliest occupation, it was about 7-8 kilometers (4-5 miles) in from the Peruvian coast and today is about 40 meters (130 feet) above sea level. The site was a fishing community, with a Terminal Pleistocene occupation date between about 13,000 and 11,400 calendar years ago (cal BP), based on a large suite of radiocarbon dates. Terminal Pleistocene sites are known in  Andean chronology as Preceramic Period I). The site is one of about 60 sites which have been found along the coast of Peru in this region, but it is the only one containing the Jaguay Phase occupations, and it is the earliest site in the region found to date (as of 2008, Sandweiss). The closest site with the same date is Quebrada Tacahuay, some 230 km (140 miles) to the south. It, like Quebrada Jaguay, is a seasonally-occupied fishing village: and those sites and many others extending from Alaska to Chile support the Pacific Coast Migration Model for the original colonization of the Americas. Chronology Late Preceramic Period, 4000 cal BP, Manos PhaseHiatus, 4000-8000 cal BPEarly Middle Preceramic Period, 8000-10,600 cal BP, Machas PhaseEarly Preceramic Period, 11,400-13,000 cal BP, Jaguay Phase During the Jaguay phase, the site was a seasonally-occupied coastal base camp for hunter-gatherers and fishermen who targeted mostly drum fish (Sciaenae, corvina or sea bass family), wedge clams (Mesodesma donancium), and freshwater and/or marine crustaceans. The occupations apparently were confined to the late winter/early summer months; the rest of the year, the people are believed to have moved inland and hunted terrestrial animals. Based on the size of the fish, the people were net fishing: the Machas phase occupations contain a few specimens of knotted cordage. The only terrestrial animals recovered from the site were small rodents, which were not likely food for the residents. Houses during the Jaguay phase were rectangular, based on the identification of postholes, and contained hearths; the houses were reconstructed several times in the same location but slightly different positions, evidence for seasonal occupations. Food remains and abundant lithic debitage were also recovered, but there were almost no finished tools. Poorly preserved plant remains were restricted to a few prickly pear cactus (Opuntia) seeds. The vast majority of the raw material for the stone tools (lithics) were local, but Alca obsidian identified by Instrumental Neutron Activation Analysis had been brought from its Pucuncho basin source in the Andean highlands some 130 km (80 mi) away and 3000 m (9800 ft) higher in elevation. Machas Phase The Machas Phase occupation at the site contains neither prickly pear nor obsidian: and during this period there are many more such villages in the region. The Machas phase occupation included several bottle gourd rind fragments; and a single semi-subterranean house, about 5 m (16 ft) in diameter and built with a foundation of mud and stone. It may have been roofed with wood or other organic material; it had a central hearth. The house depression is filled with a shell midden, and the house was also built on top of another shell midden. Archaeological Discovery Quebrada Jaguay was discovered by Frà ©dà ©ric Engel in 1970, as part of his investigations into the preceramic epoch along the coastline. Engel dated charcoal from one of his test pits, which came back to a remarkable 11,800 cal bp, unheard of at the time: in 1970, any site in the Americas older than 11,200 was considered heresy. Excavations were conducted at the site by Daniel Sandweiss in the 1990s, with a team of Peruvian, Canadian and U.S archaeologists. Sources Sandweiss DH. 2008.

Standardized Testing The Real Threat to American Schools...

Standardized testing requires student to answer same or similar questions with given answer choices that are often in multiple choice or true or false form. Dating back from 2200 B.C standardized testing is recorded being used in China ,where people applying for government jobs had to take an examination ,testing their knowledge on confucian philosophy and poetry.During the mid-1800s in Industrial Revolution ,soon after child labor laws were enacted taking children out of farms and factories and putting them into schools the use of standardized test was introduced to America in Boston. Standardized testing was being used to compare schools and teaching quality; Boston’s program was soon adopted nation wide. Types of standardized test†¦show more content†¦These forms of test either overestimate students or underestimate them. Often students that test well usually cannot explain how they got the answer they did or why it is right. Meanwhile, standardized tests are unfa ir to the students who are brilliant thinkers,but do not test well. Wrong answers do not always mean an absence of understanding , just like correct answers do not alway indicate understanding. Though multiple choice and true or false format present many problems it is easier to agree on a correct answer of a basic criteria multiple choice question than a on deeper level of thinking, essay question ,therefore making the tests easier and faster to grade.This belief that efficiency is a high priority that effectiveness is leading to a decline in teaching because standardized test do not require an reason behind answers most teachers teach for the sake of testing and sadly, not for the sake of learning. This type of teaching is often referred to as the ‘drill and kill’ method and involves students memorizing isolated information that ‘might’ be on the test. This form of teaching does not allow students to understand the information in a way that they might apply it to other situations other than testing. Those students who are not taught in a ‘drill and kill’ technique and can analyze and make connections are often asked to ‘dumb do wn’ for theShow MoreRelatedThe Dangerous Myth Of Grade Inflation1279 Words   |  6 PagesMyth of Grade Inflation,† Alfie Kohn sets out to determine if grade inflation is indeed fact or fiction.

With reference to a case study on Brazil, explain what affects rural to urban migration Free Essays

The following essay is based on a case study of Brazil. I will describe and show the problems of rural to urban migration. The two locations we will be studying are the Caatinga and a city called Belo Horizonte, both located in Brazil (see map below). We will write a custom essay sample on With reference to a case study on Brazil, explain what affects rural to urban migration or any similar topic only for you Order Now Rural areas are areas isolated from city centers with very little communication and transport to them. They are very poor areas with little agriculture. Urban areas are city like places where communication, transport and living conditions are acceptable. The Caatinga is one of the most remote areas of Brazil. It is a dry and poor area. It is the largest dry region in South America. The vegetation in this area is very pitiable. Population Pressure happens a lot here. Many people are born and are forced to live in such disgraceful conditions. It is situated in the North-eastern part of Brazil. The Caatinga has serious problems including health and, the most important one, there is a lack of jobs. Another major problem are droughts. Approximately once every ten years, a drought occurs causing large disasters in matters of agriculture and health. Climate also plays a big role in the daily life of the Caatinga inhabitants. The other location we are going to study is Belo Horizonte. It is a town located in the south-eastern part of Brazil. I’m going to concentrate on the surroundings (suburbs) of the town known as the Favelas. These are groups of houses, now changed into neighborhoods where people that migrate from the Caatinga and other rural areas of Brazil move too. Here the houses are mostly wooden shacks or the better ones are made with cement and bricks. Here there is little electricity and water. Living conditions are much better than in the Caatinga. There are more job opportunities for migrated people with no money. People that migrate to these places, in most cases leave the Caatinga with no money at all and will have to live under cardboard boxes until they can afford to build there own shack. You can read also Classifications of Restaurants The most important factor that affects migration are the Push and the Pull factors. Push factors are negative factors. These could include such things as health, education, general living conditions etc. The Pull factors are positive factors. These include things like electricity provided, clean water, better health etc. In this case study, the push factors will be about the rural areas (Caatinga). The pull factors will be about the urban area (Favelas). Migration is affected by these factors. In this study the most important ones are health, climate, job opportunities, education and living conditions. The problems that people face in the Caatinga are very serious. This is why people want to migrate or even are forced to migrate to urban places and Favelas. They do this to try and gain some money and to give better future for their children. Droughts are very common in the Caatinga. When these occur, rivers can dry up and there is no water to drink and to use for agricultural reasons. This brings every time famine, starvation and disease. People can only drink from dirty ponds formed when the last rain had fallen. Illiteracy is another great problem. There are no schools for people to go to. Most of the population cannot read nor write. Children cannot learn how to write and this is why when they migrate, they will have very underprivileged jobs with very little pay. When droughts occur, agricultural land is destroyed along side with all of the crops grown during the year. This brings long periods of time with no one working on the land which means no jobs. With no jobs, people have no money and cannot buy food nor medicines for their family. When the harvesting fails, people can only eat lamb and beans throughout the year until the next harvest is ready. There is no medical care in these areas. Diseases such as Malaria strike young children and elder people causing death rates to increase drastically. This also is connected with transport. Ill and sick people cannot be transported to cities to be taken care of. No food can be imported to the Caatinga. The population of the Caatinga can only live on what they produce, this is called subsistence farming. The climate has also a very important job in the Caatinga and is one of the biggest factors causing migration. All through out the year there is little or no rain at all in some areas of the Caatinga. The temperatures are very high in the summer (reaching over 30à ¯Ã‚ ¿Ã‚ ½) and in the winter are very cold (approximately 10à ¯Ã‚ ¿Ã‚ ½). You can read also Costco Case Study Families in the Caatinga are very large. Some families have up to 15 children and in some cases can reach 20. This is because people want to have more children so that they can be maintained when they reach an older age. Another reason is that diseases can easily kill many children. On average out of 10 children, 5 die of illnesses or starvation. In the Caatinga child labor is also a big concern for the government. Many children are used to farm on the land which isn’t of their property. People from the Caatinga decide to migrate to urban cities like Belo Horizonte. They have to walk for hundreds of kilometers with all of their belongings and no money. When they arrive in the Favelas, they have to set up a new life. The Favelas are situated just outside cities. These are groups of houses built by migrates coming in from the rural part of the country. Here their children can receive an education from proper schools. They learn how to read and write so that in the future they will be able to have a better job. Once they reach an older age, children will have to start working to try and get some money for their numerous family. In a case we saw, the money that the father and her daughter earned was à ¯Ã‚ ¿Ã‚ ½12 a month, just enough to maintain their big family. They cannot spend any of it on leisure and entertainment. With the money they can buy proper food from markets and are able to feed the whole family. They can also buy medicines and with time, they can improve their household. The birth rate here is also much lower than in the Caatinga. This is because health is much more advanced and people don’t need as many children to maintain them. The death rate is also much lower than in the Caatinga. Medicines to cure diseases are introduced and hospitals are nearby. Electricity and sometime running water in houses is introduced. This is a necessity for many families. The transport and communication is good here. The only problem is that there is no entertainment in these Favelas (no cinema, shops, restaurants etc†¦). The climate here is much better. The temperatures are quite high throughout the year and the rainfall is balanced. In conclusion to my essay, the urban environment is a much better place to live in because of all its pull factors. Urban population is increasing rapidly, 78% of Brazilian population lives in Urban population whilst the other 22% is spread out between rural and Amazonian. I would prefer to live in an urban environment because of all the comforts it can provide compared to the Caatinga. Still people don’t have power over their actions. People living in the Caatinga cannot decide weather to move or not. It is a risk they have to take and only some families can take it. It would be hard to help the population of the Caatinga. Brazil, being in some parts a developed country and in others, not developed at all, would find it difficult to provide the funds to help this population. It would need to build a new transport system, including a railway and more roads. It could also build hospital facilities and refugee camps for homeless people. It should improve agricultural facilities adding irrigating systems and it should bring, using aqueducts, water to remote villages. This could also bring problems because people living in the Caatinga might not want their land to be industrialized. Also the funds to help could be received from the population of urban cities which might disapprove. Rio de Janeiro has tried to improve living conditions of the Favelas by expanding its land and becoming the second largest city in the world. It has built on a flat piece of land tall buildings for rich people to move in. It is a much safer place for people to live in. It is actually become a new city called Barra. Barra is one of the safest cities in South America. It has the largest shopping mall in all of South America. The criminality is very low. By building this city, Rio de Janeiro has stopped growing because people move out to Barra more. Soon Barra will become as large as Rio and suffer the same problems if migration doesn’t stop.
