Australopithecus Facts and Figures

Name: Australopithecus (Greek for southern ape); pronounced AW-strah-low-pih-THECK-usHabitat: Plains of AfricaHistorical Epoch: Late Pliocene-Early Pleistocene (4 to 2 million years ago)Size and Weight: Varies by species; mostly about four feet tall and 50 to 75 poundsDiet: Mostly herbivorousDistinguishing Characteristics: Bipedal posture; relatively large brain About Australopithecus Although theres always the possibility that a stunning new fossil discovery will upset the hominid apple cart, for now, paleontologists agree that the prehistoric primate Australopithecus was immediately ancestral to genus Homo, which today is represented by only a single species, Homo sapiens. (Paleontologists have yet to pin down the exact time when the genus Homo first evolved from Australopithecus; the best guess is that Homo habilis derived from a population of Australopithecus in Africa about two million years ago.) The two most important species of Australopithecus were A. afarensis, named after the Afar region of Ethiopia, and A. africanus, which was discovered in South Africa. Dating to about 3.5 million years ago, A. afarensis was about the size of a grade-schooler; its human-like traits included a bipedal posture and a brain slightly bigger than a chimpanzees, but it still possessed a distinctly chimp-like face. (The most famous specimen of A. afarensis is the famous Lucy.) A. africanus appeared on the scene a few hundred thousand years later; it was similar in most ways to its immediate ancestor, although slightly bigger and better adapted to a plains lifestyle. A third species of Australopithecus, A. robustus, was so much bigger than these other two species (with a bigger brain as well) that its now usually assigned to its own genus, Paranthropus. One of the most controversial aspects of the various species of Australopithecus is their presumed diets, which are related intimately to their use (or non-use) of primitive tools. For years, paleontologists assumed that Australopithecus subsisted mostly on nuts, fruits, and hard-to-digest tubers, as evidenced by the shape of their teeth (and the wear on tooth enamel). But then researchers discovered evidence of animal butchering and consumption, dating to about 2.6 and 3.4 million years ago, in Ethiopia, demonstrating that some species of Australopithecus may have supplemented their plant diets with small servings of meat—and may (emphasis on the may) have used stone tools to kill their prey. However, its important not to overstate the extent to which Australopithecus was similar to modern humans. The fact is that the brains of A. afarensis and A. africanus were only about a third the size of those of Homo sapiens, and theres no convincing evidence, aside from the circumstantial details cited above, that these hominids were capable of using tools (though some paleontologists have made this claim for A. africanus). In fact, Australopithecus seems to have occupied a place fairly far down on the Pliocene food chain, with numerous individuals succumbing to predation by the meat-eating megafauna mammals of their African habitat.

Health Information Exchange Free Essays

An electronic health record is a patient’s medical information stored elect-ronically instead of on paper. The concept has been around since the 1960s. Improvement of patient medical care was and is the catalyst for the electronic health record. We will write a custom essay sample on Health Information Exchange or any similar topic only for you Order Now There are several advantages to using electronic health records. For instance, access to patient medical records is not limited to the location of the paper chart, but is available at the patient point of care. The health care provider has up-to-date information regarding every aspect of the patients medical history. Including test results, medications, allergy information, ect. All of which are crucial for making informed medical decisions. Patient safety and better patient care are also advantages of the electronic health record. Illegible handwritten notes, orders, and prescriptions has been eliminated with the EHR. Now, reports to specialists or patients are comprehensible, professional, and easy to create. And because of the availability of more thorough clinical information, improved patient care is inevitable. Another advantage to the EHR is efficiency and financial savings. The elimination of paper charts alone can greatly reduce the costs of storage and retrieval for these charts. Another major source of growth in healthcare costs comes from medical imaging. Access to patients images in an EHR is an effective way to avoid duplicating expensive imaging procedures. Another cost to healthcare is the printing and mailing of checks. If all medical payment transactions were handled electronically, America could save up to $11 billion annually. For all these reasons that I have listed, I think that the advantages of Electronic Health Records far out weigh the disadvantages. The health care industry is rapidly evolving and the implementation of EHR is crucial in order for clinics and physicians to maintain extensive patient documentation to ensure that they meet†¦ How to cite Health Information Exchange, Papers

Why do the principals of Arundel Partners think they can make money buying movie sequel rights? Do you expect any major film studios to be interested in the sort of arrangement described in the case? Why do the partners want to buy a portfolio of sequel rights all at once rather than negotiating film-by-film to buy each? 2. How should one translate the data in this case to structure the valuation of sequel options to tailor it for the Black-Scholes approach, to valuing Call options on a Stock with a traded market value process? In particular, what numbers should be assigned to: †¢ †¢ †¢ †¢ The â€Å"primitive asset value† underlying sequel value (on average), for a â€Å"representative† (scale adjusted) film; The exercise price for a sequel option to be executed; The relevant time horizon (maturity) of sequel options; The variance rate of the underlying asset values/returns to use for calculating the relevant Black and Scholes Call option value, of the option to produce a sequel film? In light of the assumptions made regarding the above, how much should be paid for the rights to produce the sequel for an average-scale original production? How do the computed Black-Scholes formula-based Sequel Option Values compare with more naive valuations, based on either (i) exercising ALL sequel options, or (ii) making sequels ONLY for those films in the sample which resulted in sufficient profitability of the first?
