Mungo Man
History Assignment ââ¬â Mungo Man The discoveries at Lake Mungo are potentially the most important discoveries made in Australia, if not the world. The skeletal remains uncovered a world that we know very little about. They gave us an insight to the burial practices of the earliest people for both males and females of the time. The skeletal remains were subject to numerous forms of dating, but primarily radiocarbon dating or C-14 dating. Mungo I also known as Mungo woman or LM1 was the first skeleton to be discovered at the site. In 1968 geologist Jim Bowler was conducting research on the Willandra Lakes region, more specifically Lake Mungo. His original intention for the site was to study the Pleistocene layers of the area, looking at the ancient geography of the land. However in one of the lunettes (extended, crescent shaped sand ridges) he happened to notice a bone fragment protruding from an exposed calcrete block. Upon closer inspection he realised that it was not animal but human. Bowler marked the site with a peg for further excavation by archaeologists. Similarly in 1974 Jim also discovered Mungo III/LM3, this time dubbed Mungo Man. His skeleton was discovered after a prolonged period of rain in 1973. The rain has eroded the outer layers of the dirt to reveal a carbonated human skull. These remains were discovered just some 500m from the site of Mungo I. Again marked and excavated later on by archaeologist. Mungo I was the remains of a woman. She was described as a gracile woman, with fine bones and features. She was not found as a whole intact skeleton, rather 175 bone fragments. It was concluded that she was cremated; the charring of the bone fragments supported this theory. From this primary evidence we can hypothesise that the people of the time believed in the ritual passing of an individual, that the deceased should have a physical recognition of the change between the worldly life and the afterlife. We can also guess that from this they had some sort of belief system. Mungo III is an example of how the people of his time treated the males in the society. Instead of the cremation seen in Mungo Woman, this male, again gracile in appearance was instead buried in the ground. Again there is evidence of a ritual burial in the way he was laid. His hands were clasped together and red ochre sprinkled over the body. This arrangement of the body again demonstrates a belief in passing to another world by making the body presentable to this other world. There were numerous ways that the remains have been dated. By using the dated layers that the bones were found in and C-14 dating we are able to get a fairly accurate estimate of when these people were buried. Other ways included electron spin resonance dating, uranium-thorium dating, optically stimulated luminescence dating and thermoluminescence dating. Paleoanthropologists, or people who specialise in studying ancient humans by looking at human fossil primary evidence carried all of these dating methods out. When first discovered in 1968 and 1974 Jim Bowler was able to use his own scientific field of geomorphology. By using the already dated layers that the bones were found in he was able to produce and estimate time of burial. He estimated the bones of LM1 to be around 40,000 years ago and LM3 to around 32,000 years ago. He was able compare the strata of the area and the two skeletons to come up with these estimations. Archaeologists soon came in in the years following each discovery to uncover the remains. After Archaeologists had removed the bones they were handed over to paleoanthropologists and aboriginal peoples for proper testing. The first and most commonly known dating method that they used on the skeletons was radiocarbon or C-14 dating. The second way that archaeologists were able to date the Lake Mungo remains was by electron spin resonance dating. Also known as ESR dating, this method of dating the archaeologist/scientist looks to the radiation damage of bones (mostly teeth) by looking at the amount of radiation an object has been subject to whilst under ground. ESR dating works best on animal teeth so even though the results are still plausible it provided a much larger date area. The results reached showed the conclusion that the bones were around 31, 000 years old for Mungo Man give or take 7, 000 years. This of course would bring the reliability of this method down. Another dating technique they used on the skeletal remains was uranium-thorium dating. Instead of looking at how much of a particular substance is missing uranium-thorium dating records the accumulation of equilibrium between the isotope thorium-230 and its radioactive parent uranium-234. It is useful for determining the age of objects containing calcium carbonate, like bone. This was combined with optically stimulated luminescence dating, where you uncover when the material was last exposed to light to bring an estimate of 62,000 years ago for Mungo III à ± 6,000 years. This caused controversy and confusion though as the surrounding earth was dated only to 43,000 years. This questions the reliability of these results as not all the facts interlink with each other. While individually these dating methods are quite reliable combined they produce relatively farfetched results. Thermoluminescence dating works in a similar way to optically stimulated luminescence dating in that it measures when it was last exposed to light but also when it was last exposed to heat. By using this technique the bones were dated to no more than 24,600 à ±2,400 years but no less than 43,300 à ±3,800 years ago.

Child and Elder Abuse Essay Example | Topics and Well Written Essays - 750 words
Child and Elder Abuse - Essay Example The elders and children comprise the largest percentage of such. In relation to the aforementioned situation, this paper will study some case of elder and child abuse and the effects of which on the victims. Doris Racher entrusted her mother, Eryetha Mayberry, a 96-year old dementia patient; in a nursing home in Oklahoma City. The daughter noticed that some items she bought for her mother were missing. Consequently, she placed a motion activated camera that looked like an alarm clock inside the room of the elderly woman. Nevertheless, instead of capturing the thief, the camera caught the grievous acts of Mrs. Mayberryââ¬â¢s caregivers. One stuffed latex gloves in the mouth of the patient while another scorned and tapped her on the head. Then, lifting the old woman from her wheelchair, they threw her to her bed and eventually, one gave her a number of heavy-handed chest compressions. The patient died soon after (Hoffman, 2013). It has to be noted that the woman was suffering from dementia so that it could perhaps be safely concluded that the abuse may have started early on. However, the woman did not report any of the events because of her mental condition. In addition, with her age, she might not just have been mentally but also physically incapable of reporting her abusers. From the said report, one can easily see that the immediate result of the physical abuse on the elderly is death. Since elders are physically weak, they can easily suffer from any physical abuse inflicted on them. For instance, the heavy-handed chest compressions may have broken some of the old womanââ¬â¢s brittle bones which might have resulted to her death. It might be true that she is already old and her death is just waiting to happen but the fact that she was physical abused is a contributing factor to her death. Other results of elder abuse could be wounds, physical
Security Incident Case Study Essay Example | Topics and Well Written Essays - 250 words
Security Incident Case Study - Essay Example This paper seeks to describe how effectively an emergency incident that occurred in Los Angeles International Airport (LAX), at 2:38pm, Terminal 4, would have be managed and highlight how effective airport operators can be, when during emergencies. In this case, where a man trespasses through a restricted doorway, there is actually no need for the crew to lower security gates and order out everyone off the secured gate including the passengers who are already aboard waiting to depart. Since itââ¬â¢s a breech that is only confined to a limited space, the best thing to do would be; assuming that the cameras in that terminal are working, trail the person in question quietly and swiftly without drawing unnecessary attention from the other parties. The evacuation process is so hectic and time consuming; and one that would literally paralyse operations throughout the entire airport. In addition; and as observed in our case study, it is more likely to cause a lot of panic and confusion, in turn making the whole process of trailing the individual in question futile. Finally, given that people will be aware of an anomaly happening at the airport; it is more likely to trigger unexpected reactions. People may start running and in the process injure each other. In conclusion, as analysed in the paper, as an airport operator, your duty is not to bring about confusion and add complexity to arising problems. With this case, and other emergency issues that arise, it is the airportââ¬â¢s duty to ensure that the safety of everyone is guaranteed and the simplest method is used in combating any possible

Theory Essay Example | Topics and Well Written Essays - 500 words - 1
Theory - Essay Example Correspondingly, theory is science is a logical and mathematical explanation, a framework describing the relations between phenomena, a set of universally true laws and principles, a testable, self-consistent model of reality, derived from the systematic observation of natural phenomena and conditions and capable of predicting future events and development of things. Ta scientific theory can always be verified by further investigations, be it an experiment or an empirical observation. The word theory comes from Greek theoria, which means ââ¬Ëspeculation, contemplation.ââ¬â¢ It also can be traced back to the word theion, meaning divine thing, so that theory means contemplation on the divine organization of the nature. A scientific theory is formulated through scientific method. A scientist makes some hypothesis on the basis of observations, predicting possible outcomes. Then predictions are tested experimentally. New observations can confirm the hypothesis or refute it. Depending on whether the hypothesis is confirmed or refuted, it can be adjusted or redefined. In case the old theory is not confirmed within a new context, a new theory can be proposed (p.8). Often numerous hypotheses are bound within one theory. Theories deal with broader sets of universals than hypotheses. There may be several theories about the same part of reality, all of them revealing some truth. However, one theory may be superior to other competitive theories. Then it becomes a framework within which theoretical facts and observations are explained and predicted (Dodig ââ¬â Crnkovic 2001, p.8). According to Karl Popper (1963) a scientific theory has the following characteristics: 1) It can be easily verified and confirmed. 2) Confirmations are sound if the prediction is risky and there have been expected an event able to refute the theory. 3) A scientific theory always forbids some things to happen. 4) A scientific theory is always refutable by some fact of event.

Work Schedule Assignment Example | Topics and Well Written Essays - 500 words
Work Schedule - Assignment Example Given this consideration, it is imperative to come up with a low cost customer service employee daily assignment schedule. The aim of this study was to utilize Linear Programing (LP) to review low- cost customer service employee assignment schedule options. The additional objectives included were to depict the necessity to test theses results for sensitivity to different constraints in order to include a number of total part time and increased labor cost due to non typical days. These models were created by the use of the Microsoft Excel solver to calculate the LP model. The variety of constraints that were included were: a minimum number of customer representatives per hour, mandatory full time shift schedules include a lunch break of one hour, a standard pay for full time and part time employees, a maximum number of total part time hours and ultimately, a requirement to minimize total wage costs (Tsogas, 2001). The results form the excel sheet indicate than scenario 3 will be the best as it is efficient and effective. This scenario allows for a minimum and a maximum number of full time employees per shift to maintain minimum levels of leadership with our customer services staff at all times, reasonable lunch and dinner will schedules and a maximum part time hours contribution of 50 percent. This will ensure a relaxation of the 50% constrain on the hours that will be worked on by part time customer service employees. Based on the requirements of the proposal to develop a minimum cost daily assignment schedule for the customer service employees at the Acme Mexico city star, the table will show a clear indication of how the LP model was developed to achieve optimal efficiency at a minimal cost to the company (DuBrin, 2009). From the table, it is evident that an integer Liner program was developed to address the labor restrictions amongst other consideration that were brought forward. The model used the develop this assignment

Battling Obesity in Adults with health promotion programmes Essay
Battling Obesity in Adults with health promotion programmes - Essay Example The research paper ââ¬Å"Battling Obesity in Adults with health promotion programmesâ⬠examines the unhealthy lifestyle habits and ways of preventing a serious contemporary public health issue, obesity. Obesity is becoming very common with the current lifestyles of people. Nowadays, life is made more convenient by technology and the accessibility of basic needs. For example, instead of walking to the store to buy things, one can just call for delivery. Instead of cooking food from scratch, one can just buy ââ¬Å"fast foodâ⬠or heat up instant meals in the microwave oven. These lifestyle habits are likely to cause weight gain in people especially if they do not engage in physical activities. If not controlled, it can even lead to obesity. It is posing a big health problem not only of the individual but for families and society in general. Overweight and obese individuals have an increased risk to illnesses and disease such as heart disease, stroke and other deadly diseases . Hence, a health awareness program for the prevention of obesity as well as some interventions to treat obesity should be put in place. It is part of the nursesââ¬â¢ duties to ensure the health and well-being of patients through preventative strategies such as health promotion. Since being overweight and obese is getting to be more common, nurses need to be educated on its risks, causes and prevention so they can explain it well to their patients, as well as practice healthy living themselves so as to keep physically fit. (Sellwood, 2013). With life/work getting more complicated and busy, people resort to fast food for convenience, but these are all filled with processed ingredients which are not healthy to consume (Tiggermann, 2004). Instead of such convenience food, nurses can advise their patients to eat freshly cooked food, fresh fruits and vegetables for better nutrition. Preparing food from scratch may take more time and effort, but nurses need to emphasize to their patien ts that these are better for them in the long run, as their health should be their priority. In order to be credible nurses, they need to model their conviction to be healthy. That is why they need to equip themselves with the knowledge and skills to implement appropriate health promotion programmes (Hayden, 2008; Azjen, 1985; Ewles & Simnett, 2004). Obesity exists when there is an excess fat in the body which adversely affects the health and well-being of individuals. (Mascie-Taylor & Goto, 2007). The body fat is measured with the body mass index (BMI). Brewis (2010) shares that when the BMI level of an individual goes over 25 kg/m2 , then he or she may be classified as overweight. If the BMI level reaches 30 kg/m2 and over, then it is already classified as obesity. Currently a major health problem, obesity contributes to increased morbidity and mortality among adults. It makes them more vulnerable to cardiovascular illnesses. The significant increase in mortality of obese patients with cardiovascular disease is a cause for alarm (Parsons et al., 2005). Obesity has likewise been associated with other medical conditions resulting in human suffering and health care costs, becoming an increasing burden to those afflicted with it, their families, and the government (Finkelstein et al. 2003). It is considered the fifth major cause of death globally as more than 2.8 million deaths annually result from this disease (WHO, 2011). It has also been reported that more than 23% of ischaemic heart disease, 44% of diabetes and 7% to 41% of some cancer burdens are caused or aggravated by obesity (WHO, 2011).
