Essay on Monkey See, Monkey Do - 757 Words

Violence in media today is almost as common as a teenage girl knowing the name of the actor Channing Tatum. In America, we practically grow up on movies that display countless acts of violence against one another. This is a major way in which human society as a whole has changed from growing up in an environment with a lot of real life violence sporadically around the world, to having some sort of physical conflict involved in every movie or TV show. In the past there have been several cases where people have seen a violent action through a media source and then tried carrying out an action similar to the one seen, except in real life. This is proof to an existence of the presence of violence having an impact on certain viewers. Violence†¦show more content†¦Although they viewed the video multiple times, there must have been some sort of mental sickness for the two teenagers to commit an act like this. It will never be proven that the movie was truly responsible but you have to wonder, if the movie weren’t made, would Bill Savage be dead right now? To make Bok’s case, she cites the legal action that was taken in this case: if you refer the film to a product and something goes wrong with the product then the makers are held responsible. This ruling is huge in the verdict for having unrestricted amounts of violence in a production and should make them think twice about the content which they are displaying. On the flip side to this there is another view in which a certain level of violence is actually beneficial to the viewer. Author Gerard Jones in his article titled â€Å"Violent media is good for kids† exhibits this perspective of violence at a certain level actually teaching kids to be strong and unafraid. This view comes from a personal experience where the author was able to overcome things that held him back as a child such as being afraid, unsocial, and unconfident in himself. I see where someone could find that kind of urge to be self-confident after watching a movie such as The Incredible Hulk, but if that same movie leads a teenager to commit a crime, then it is not worth it. A kid can find some other way to conquer his fears such as finding friends or going to his or her parents for help on howShow MoreRelatedThe Weirdest Creature Of Nature Essay1079 Words   |  5 Pagesanimals.

Biblical Archaeology Dating Techniques Free Essays

string(219) " as thinning of stands, resin-gathering, fire damage, and other traumas such as severe weather effects, pollution or lightning damage, not to mention shaping of the wood at the time of construction and decay afterward\." As our civilization grows, there is also a growing passion for knowledge of the past. Archaeology is fast becoming one of the popular sciences. Most archeological finds are composed of shreds of pottery or ceramics. We will write a custom essay sample on Biblical Archaeology: Dating Techniques or any similar topic only for you Order Now As archeology and modern science progress many dating techniques are being developed to be used on these fragile artefacts in order to give us a brief glimpse of our past. Many techniques are now available which allow the detailed physical and chemical characterization of ceramic artefacts. Given a suitable archaeological sample it is now possible to determine many aspects of technology, provenance, and, in some cases, its use. Several dating techniques used in archeology are superposition, artifacts of known age, stratigraphy, dendrochronology and thermoluminescence. This paper shall focus on Ceramic Analysis using three of these techniques: Dendrochronology, Radiocarbon dating and Thermoluminescence. Carbon 14 Radiocarbon dating or Carbon-14 dating is the determination of the approximate age of an ancient object, such as an archaeological specimen, by measuring the amount of carbon 14 it contains. Radiocarbon dating was discovered by a team of scientists led by Prof. Willard Libby of the University of Chicago after World War II. Since plants and animals take up carbon-14 during their lifetime. The amount of carbon-14 in them exists in equilibrium with the C14 concentration of the atmosphere and the ratio of C-14 to C-12 remains about the same as the ratio in the atmosphere. As soon as a plant or animal dies, they cease the metabolic function of carbon uptake; there is no replenishment of radioactive carbon, only decay. This rate of decay was calculated by Libby’s team to be 5568 years per half-life, this means that half the C14 in the original sample will have decayed after 5568 years and after another 5568 years, half of that remaining material will have decayed, and so on. This rate of decay is what is now know as Libby’s half-life which he measured at 5568 ±30 years. The true advantage of the radiocarbon method is its capability to be uniformly applied throughout the world , this is probably the primary reason why it is one of the most widely used and best-known absolute dating methods. However, it is not without its flaws, radiocarbon dating has the following limitations: 1. that after 10 half-lives there is a very small amount of radioactive carbon present in a sample, at about 50,000-60,000 years radiocarbon dating becomes inaccurate. 2. the ratio of C-14 to C-12 in the atmosphere is not constant. This variation is due to changes in the intensity of the cosmic radiation bombardment of the Earth, the 1950’s nuclear testing and the depletion of the Ozone layer. 3. in rare cases, a â€Å"reservoir effect† will give C-14 dates that are much older than the true age of the sample because â€Å"some plants and animals live in very unusual environments whose C-14 content is much lower than normal. † 4. Contamination of the sample also limits the accuracy of Radiocarbon dating as when porous samples contain recently living material with a full â€Å"charge† of C-14. Finally, Radiocarbon dating can only be used on living organisms. Dendrochronology Dendrochronology is the science that uses tree rings dated to their exact year of formation to analyze temporal and spatial patterns of processes in the physical and cultural sciences. Its main function in archaeology is to use tree rings to date when timber was felled, transported, processed, or used for construction or wooden artefacts such as a beam or pole of an ancient structure. The principle behind using tree-rings is that â€Å"tree-ring sequences from trees that grow in a seasonal climate, i. e. , with one growth increment per year, with the size of that growth dependent upon some climatic stimulus such as cold in the Polar regions, drought in the Aegean, and various combinations of the two stimuli in regions in between, can be compared so that these increments, more popularly known as â€Å"rings,† can be dated to the calendar year in which they were formed. † Aside from the principle of using tree-rings, the use of Dendrochronology is governed by several other principles, these set of scientific rules must be adhered to in order for the result to be flawless. There is the Uniformitarian Principle which states that â€Å"physical and biological processes that link current environmental processes with current patterns of tree growth must have been in operation in the past,† the Principle of Limiting Factors which states that â€Å"rates of plant processes are constrained by the primary environmental variable that is most limiting,† The Principle of Aggregate Tree Growth which states that â€Å"any individual tree-growth series can be â€Å"decomposed† into an aggregate of environmental factors, both human and natural, that affected the patterns of tree growth over time,† The Principle of Ecological Amplitude stating that a specie of trees â€Å"may grow and reproduce over a certain range of habitats, referred to as its ecological amplitude,† the Principle of Sites Selection which states that â€Å"hat sites useful to dendrochronology can be identified and selected based on criteria that will produce tree- ring series sensitive to the environmental variable being examined,† the Principle of Cross-dating which states that â€Å"matching patterns in ring widths or other ring characteristics (such as ring density patterns) among several tree-ring series allow the identification of the exact year in which each tree ring was formed. † and the Principle of Replication which states â€Å"that the environmental signal being investigated can be maximized, and the amount of â€Å"noise† minimized, by sampling more than one stem radius per tree, and more than one tree per site,† the application of which is not limited to Dendrochronology only. The methodology used in Dendrochronology is cross-dating, or matching patterns of ring-growth from one tree to another and assigning rings to specific years, however, this possible only among trees growing in the same general climatic region. The good thing about dendrochronology on the other hand, is that cross-dating can sometimes be achieved in spite of human interference to ring-growth such as thinning of stands, resin-gathering, fire damage, and other traumas such as severe weather effects, pollution or lightning damage, not to mention shaping of the wood at the time of construction and decay afterward. You read "Biblical Archaeology: Dating Techniques" in category "Papers" Furthermore, visual and statistical techniques are employed to guarantee the accuracy of the matches and in addition to simple ring-width analysis, X-ray densitometric methods are used to reconstruct past environmental conditions. It is also possible that wood or charcoal samples taken from standing buildings or excavated from archaeological sites be crossdated with each other and with wood from living trees to extend the tree-ring chronology beyond the date of the oldest ring of the oldest living tree in the region. Scientists believe that the best advantage of dendrochronology is that it is the only archaeometric technique where determination of absolute dates accurate to the year is either theoretically or practically possible, but, just like any other method of dating artefacts, it suffers from several limitations. The following limits the use or accuracy of Dendrochronology: 1. in some areas of the world, particularly in the tropics, the species available do not have sufficiently distinct seasonal patterns that can be used 2. in cases where the right species are available, the wood must be well enough preserved that the rings are readable to the point that there must be at least 30 intact rings on any one sample. 3. in order to produce an accurate result, it is necessary to have samples of timber that retained their bark, so that it is clear which ring was the outermost when it was felled. 4. it can only be used if there is an existing master strip for that area and species; if the only master chronology available for the region is oak, cross-matching with timbers of these other species cannot be relied on. 5. use of this technique is also limited on how far back in the past things can be dated with tree rings although bristle cone pine trees can live to 9,000 years, this is a very rare phenomenon. 6. â€Å"sapwood is highly susceptible to decay particularly by beetle larvae and as a â€Å"result all sapwood may have been removed from the accessible surfaces of timbers during building repairs and conservation work, making it impossible to determine when the timber was felled. † 7. it may give inaccurate results on the actual date of the structure if it so happens that the date the timber was felled is not necessarily the date that the building was constructed or that the timber used was imported from another area. 8. in some places, prehistoric people may have built their structures using timber however, in most of the world that did not begin to happen until about 4,000 to 5,000 years ago. Thermoluminiscence Thermoluminescence dating is the determination by means of measuring the accumulated radiation dose of the time elapsed since the material containing crystalline minerals was either heated or exposed to sunlight. The application ranges from â€Å"Lower Paleolithic to Neolithic archaeological sites, with a major focus on the Middle Paleolithic, which is often beyond the range of the radiocarbon method. † The principle behind this unique dating technique is based on the â€Å"storage of information about the absorbed radiation in inorganic crystals. † It is based on structural damage and faults to the crystal lattice of minerals by ionizing radiation. The sources for this omnipresent radiation are radioactive nuclides from the surrounding sediment and from the sample itself, as well as secondary cosmic rays. Thus a radiation dose accumulates in the crystal in the form of electrons in excited states, of which some are metastable and thus resident over periods of time long enough to allow a dating application. During the first heating of the artefact, if the temperature is high enough (400 ° C), the drainage is sufficient to relax all electrons relevant to the luminescence method used; that is, the clock is set to zero and through the years it starts to accumulate natural radiation, upon its second heating it releases all this stored radiation in terms of thermoluminescent light. The released light is then correlated to the absorbed radiation which is then correlated to the archeological age. In practice, knowledge of the composition of the artefact is of importance since the nature or chemical composition of it, as explained above, determines the amount of natural radioisotopes present in it. These natural radioisotopes are responsible for the greater part of the radiation that is absorbed. If the composition of the artefact is known, then the archeological age of the artefact can be computed by using the â€Å"total amount of absorbed radiation divided by the absorbed dose through internal and external radiation per year. † The greatest advantage of Thermoluminescence dating over other methods is not only the direct association of the event with past human activity on a linear time scale, but also its smaller vulnerability to unknown variation of certain parameters. However, Thermoluminescence dating is still prone to errors and inaccuracies. The evaluation and publishing of results must be done with due care and must meet with certain standards which includes the presentation of glow curves, heating- and DE-plateaus, growth curve(s) and the determination of the alpha sensitivity of each sample. Also, equal care has to be taken in the evaluation of parameters prone to variation with time. Conclusion Each of the three dating techniques discussed has its own peculiar way of finding the archaeological era that a sample was created or may have died: Radiocarbon depends on decay, Dendrochronology depends upon growth and thermoluminescence depends upon absorption. The three techniques however different they may be are still connected by a linear timeline, when the accuracy of one technique ends, another begins. Dendrochronology can only be used as long as there are master strips which may reach only up to a maximum of 9,000 years old, results obtained through Radiocarbon, on the other hand, can only be accurate up to 50,000-60,000 years old while Thermoluminescence dating ranges from 10,000 to 230,000 years old. The three dating techniques discussed have their own advantages and disadvantages. In the end, the scientist is the one who weighs all the pro’s and the con’s of any technique and he is given the discretion on what technique to use which he thinks is more appropriate and shall give out more accurate findings.

Free Essays on CIF Contract

Introduction C.I.F. stands for "Cost Insurance and Freight" In fact; this contract imposes a variety of duties to the seller. In general this contract is known as a contract for sale and shipment of goods to the agreed destination. As far as the payment is regarded, it must be made against the production of the appropriate documents according to the contract. So, in case of CIF contract the seller undertakes more obligation than the buyer. All these obligations and duties of the both parties will be examined below. The Duties of the Seller  · To ship the goods according to the contract;  · To arrange for carriage of the goods;  · To arrange insurance;  · To make out invoice to the buyer;  · To tender these documents to the buyer; However, the seller must ship the goods, which means that the seller is obliged to ship the goods to the appropriate place and on the exact date. At this point the seller has the full responsibility to determine exactly the time and the place, when and where he has placed the goods on the port. Also, he is obliged to nominate the vessel. Further, the seller has to arrange for carriage of the goods, which means that the buyer does not possess the right to sue the carrier for the breach of the contract (he is not a party of the contract). If the property in the goods has not passed to the buyer then his right to sue for any damages to the goods is not completed. So, this means that in CIF contracts the buyer does not has the right to sue the carriage for the damages. As far as the documents are regarded, the seller must tender to the buyer an invoice, a clean shipped bill of lading and an insurance policy. These documents are very important because the buyer will pay the price in exchange for the documents, and it is crucial that they are accurate. If the documents are not accurate it will cause delays and other legal problems. Even more important for CIF is that the bill of lading is the ...

At this point the seller has the full responsibility to determine exactly the time and the place, when and where he has placed the goods on the port. Also, he is obliged to nominate the vessel. Further, the seller has to arrange for carriage of the goods, which means that the buyer does not possess the right to sue the carrier for the breach of the contract (he is not a party of the contract). If the property in the goods has not passed to the buyer then his right to sue for any damages to the goods is not completed. So, this means that in CIF contracts the buyer does not has the right to sue the carriage for the damages. As far as the documents are regarded, the seller must tender to the buyer an invoice, a clean shipped bill of lading and an insurance policy. These documents are very important because the buyer will pay the price in exchange for the documents, and it is crucial that they are accurate. If the documents are not accurate it will cause delays and other legal problems. Even more important for CIF is that the bill of lading is the ...

One Trip, Ten Opportunities

One Trip, Ten Opportunities My first press trip seemed glamorous – delicious food, eco-hotels, unique sights. Less glamorous, however, was my office when I returned – overflowing emails, unfinished queries, pressing deadlines. It didnt take long to finish the one article I wrote from that press trip, but it took more than a week to finish the neglected work; in the meantime my income dipped while I played catch up. 1. Your Assignment: Before you start extra pieces from a press trip, dont neglect the one piece youre expected to do. No matter how much inspiration you may have, it is vital to do your best work on the piece you know youll sell. 2. Airline Magazines: Airline magazines, found in every seat pocket, always seek new material that covers destinations along their routes. What better way to know youre covering a suitable destination than to cover the same location as your press trip? 3. Restaurant Reviews: Press guests are often treated to delicious meals at local specialty restaurants. Take careful notes of the menu, ambiance, and price ranges, and you can submit a review to local newspapers, regional magazines, or larger markets interested in niche restaurants. 4. Hotel Reviews: If your press trip includes accommodations in boutique hotels, bed-and-breakfast inns, or other unique places to stay, take notes to create reviews just as you do for local restaurants. Explore the hotel, poke into the fitness center, check out the pool, and sample any breakfast offerings, and youll be able to create an intimate article about the property. 5. Events: Even if your trip is a general visit, you can easily pick up brochures and community magazines covering festivals, concerts, fairs, theater productions, and more. Putting those details into a round up about the areas special events can give you another piece to sell to magazines or newspapers. 6. Culture: Most press trips include local guides or drivers who are an ideal resource for cultural insights into community quirks. Ask about unusual things you see, favorite hangouts, local history, language dialects, or other unique topics that can be turned into additional articles. 7. Trip Experiences: A press trip is filled with activities – Ive gone kayaking, visited museums, toured a coffee plantation and more – and each one can be a different article. Tips for first-time kayakers, museum etiquette, how coffee grows – each topic can bring a different paycheck. 8. Networking: While the professional connections you make may not lead immediately to more work, each new contact with an editor, photographer, or writer can connect to additional markets and expertise. Follow up with a nice to have met you note after the trip to remain memorable. 9. General Tips: Instead of narrowing your focus for more articles from the same trip, broaden your reach. General tips for first-time travelers to different destinations are hot topics for travel magazines and websites. 10. Recycling: Even if all you write is one article, that article can bring in ten paychecks if you sell it repeatedly. Clever rewriting can target one article for different, non-competing markets, lining up paycheck after paycheck for the same work. After each press trip I may still come home to extra emails and work to catch up on, but when I also come home with ten new ideas and opportunities for more writing, Ive never again come home to a dip in income that can tarnish the great fun the trip has been.

Trichomoniasis Essay Example | Topics and Well Written Essays - 1250 words

Trichomoniasis - Essay Example This sexually transmitted disease is not reportable, so the epidemiologic data remains very difficult to obtain. However, it has been estimated that there are 5 million new cases in the United States each year, which is more than the sum of all cases of Chlamydia and gonococcal infections. The World Health Organization estimates that there is incidence of 173 million new infections of Trichomoniasis worldwide per year. This is also known as Trichomonas vaginitis. It is caused by the sexually transmitted, flagellated parasite, Trichomonas vaginalis. The transmission rate is high; 70% of men contract the disease after a single exposure to an infected woman, which suggests that the rate of male-to-female transmission is even higher. The parasite, which exists only in trophozoite form, is an anaerobe that has the ability to generate hydrogen to combine with oxygen to create an anaerobic environment. It often accompanies bacterial vaginosis, which can be diagnosed in as many as 60% of pat ients with Trichomonas vaginitis (Cates, Jr., 1999, S2-S7). Risk Factors: There are certain risk factors that are associated with Trichomoniasis. These include all the risk factors for sexually transmitted infection acquisition. ... There is generally a longer duration of infectiousness and a high level of asymptomatic infections, especially in men. Many women with annual Pap smear examination have asymptomatic infections. This is responsible for 25% of all cases of clinically diagnosed vaginitis. More than half of infected women and nearly 90% of infected men are asymptomatic, which increases the reservoir of people spreading the infection. Trichomoniasis increases the risks of human immunodeficiency virus (HIV) transmission and HIV acquisition (Horowitz, Mrdh, eds., 1999). Infection: The primary mode of transmission of T. vaginalis is through sexual contact. Transmission by fomites is possible, but is rarely the cause of a symptomatic infection. An inoculums of at least 10,000 organisms is needed to establish a clinically significant infection. Male-to-female transmission rates are higher than female-to-male rates; about 85% of exposed women will contract the infection. Female-to-male transmission rates are more variable, but may be as high as 70% within 48 hours of exposure. Incubation period varied between 4 to 28 days. T. vaginalis resembles anaerobic bacteria more than eukaryotic behavior in that it ferments large amounts of carbohydrates into carbon dioxide and hydrogen gases, causing bubbles. Its presence in the vaginal vault changes the vaginal microbiology-the lactobacilli disappear and anaerobic bacteria predominant. T. vaginalis swims freely in the vaginal discharge but can also attach to the vaginal wall. The cell membranes of the parasite a nd those of the host interdigitate. Trichomonas adhere to vaginal and cervical epithelial cells. T. vaginalis also infects the urethra, Skene's glands, and Bartholin glands. The

Crouching Tiger Hidden Dragon Movie Review Example | Topics and Well Written Essays - 750 words

Crouching Tiger Hidden Dragon - Movie Review Example Crouching Tiger Hidden Dragon From the Chinese cultural perspective, the theme of enlightenment refers to the empowerment and mastery into many realms, and in the context of this film, it involves detaching human attachments and achieving emptiness. This theme manifests through the two main characters of Li. The film contrasts the reality of human attachments and its significance in life with that of the emptiness which can lead to enlightenment. That is, the film views the human life as an illusion and detachment as the ultimate way to enlightenment. In the film, Li mentions his attachment to the world as an illusion thereby implying the need for emptiness for attaining the real enlightenment. According to this concept of emptiness, once a person is able to see or feel nothing of the world, then he/she can truly possess the things that are real, which would pave the way for enlightenment. This concept is similarly focused in the film, The Matrix, which represents enlightenment in a modern sci-fi dimension. The f ilm relies on the doctrine of Sunyata, or emptiness, which means everything in the world undergo constant suffering and so breaking free from it facilitates the soul to become enlightened. The director gracefully features the theme of love and even embraces a gentle romantic humanism as a result of failing emptiness. Although, as above-discussed emptiness can lead to enlightenment, when there are love feelings or attachments then emptiness is not possible thereby impeding enlightenment as well.
