Ornithomimids - The Bird Mimic Dinosaurs

As dinosaur families go, ornithomimids (Greek for bird mimics) are a bit misleading: these small-to-medium-sized theropods werent named for their similarity to flying birds like pigeons and sparrows, but too large, flightless birds like ostriches and emus. In fact, the typical ornithomimid body plan looked a lot like that of a modern ostrich: long legs and tail, a thick, rounded trunk, and a small head perched atop a slender neck. Because ornithomimids like Ornithomimus and Struthiomimus bear such a marked resemblance to modern ratites (as ostriches and emus are technically classified), theres a strong temptation to infer similarities in the behavior of these two very different types of animals. Paleontologists believe that ornithomimids were the fastest dinosaurs that ever lived, some long-legged varieties (such as Dromiceiomimus) capable of hitting speeds of 50 miles per hour. Theres also a strong temptation to picture ornithomimids as covered with feathers, though the evidence for this isnt as strong as for other families of theropods, such as raptors and therizinosaurs. Ornithomimid Behavior and Habitats Like a few other dinosaur families that prospered during the Cretaceous period--such as raptors, pachycephalosaurs and ceratopsians--ornithomimids seem to have been confined mainly to North America and Asia, although some specimens have been dug up in Europe, and one controversial genus (Timimus, which was discovered in Australia) may not have been a true ornithomimid at all. In keeping with the theory that ornithomimids were fast runners, these theropods most likely inhabited ancient plains and lowlands, where their pursuit of prey (or headlong retreat from predators) wouldnt be impeded by thick vegetation. The most unusual characteristic of ornithomimids was their omnivorous diets. These were the only theropods we yet know of, besides therizinosaurs, that evolved the ability to eat vegetation as well as meat, as evidenced by the gastroliths found in the fossilized guts of some specimens. (Gastroliths are small stones that some animals swallow in order to help grind up tough plant matter in their guts.) Since later ornithomimids possessed weak, toothless beaks, its believed that these dinosaurs fed on insects, small lizards, and mammals as well as plants. (Interestingly, the earliest ornithomimids--Pelecanimimus and Harpymimus--did have teeth, the former over 200 and the latter a mere dozen.) Despite what youve seen in movies like Jurassic Park, theres no solid evidence that ornithomimids scurried across the North American plains in vast herds (although hundreds of Gallimimus galloping away from a pack of tyrannosaurs at top speed would certainly have been an impressive sight!) As with many types of dinosaurs, though we know frustratingly little about the daily life of ornithomimids, a state of affairs that may well change with further fossil discoveries.

Essay about Broken Glass - 458 Words

Broken Glass The Glass Menagerie refers to the fragile world of dreams, and illusion. Within the play Williams uses characters who face solitary struggles in an emotionally, physically, and financially starved surrounding. During the course of the play, a glass unicorn gets broken, symbolizing the fragile nature of a dream world. Its more than coincidental that the plays title refers to the collection of glass animals that belongs to Laura. The title of the play gives symbolism to the lives of Tom, Laura, and Amanda. To find relief from his boring, tedious and stressful life along with his mothers constant nagging abuse, Tom goes to movies nobody goes to the movies night after night (1874)†¦show more content†¦Watching adventures on the movie screen offers Tom another way of living, possibly one that he wishes he could be in. Laura has withdrawn from the reality of her disability and her mothers concern by always playing with a collection of glass animals, a real glass menagerie. Whenever there was an angry exchange of words in the house Laura frequently shut herself away to her private, imaginary world to mope and finger the miniature glass world. Instead of attending Rubicams Business College, Laura has been taking walks in the park and visiting museums. I went in the art museum and the bird-houses at the zoo. I visited the penguins everyday! (1871) She is so fragile that she can hardly function in the real world. Illusion may be dangerous for Laura since the menagerie serves as a substitute for life. Amanda has lived most of her life inside a glass menagerie, refusing to accept reality about her miserable existence and the handicap of her daughter. Williams shows the family in downfall, with certain members holding badly to past visions of greatness. She does not accept the loneliness and poverty that surrounds her, but desperately clings to her romanticized version of her past Eternally play those worn-out phonograph records your father left as a painful reminder of him.

Productivity and Technical Efficiency †Free Samples to Students

Question: Discuss about the Productivity and Technical Efficiency. Answer: Introduction The report discusses on the case study regarding Big chocolate. The big chocolate is the business term that is allocated to the multi-national chocolate food producers. According to the self-described fair trade promoters, that includes the Ghanaian cooperative Kuapa Kokoo, the Big chocolate companies are the Mondelez, which owns Cadbury, Mars, Nestle and the Hershey company. Big Chocolate also refers to the political and social effects of a unifying industry. The merged buying enables the large cocoa users to handle noteworthy impact on the economies and numerous of the poor African nations who rely on the cocoa production as a significant factor of the foreign trade. The discussion elaborates on a detailed analysis and synopsis of the Ghana and Nigeria cocoa production circumstances inclusive of a PESTEL. The report also discusses the analysis of the Hershey group and the growing cocoa shortage with and the Five Forces Analysis. Summary of the Ghana and Nigeria cocoa production In country of Ghana, cocoa is referred to as the king with the manufacture of the cocoa accounting for just under a sixth of the countrys Gross Domestic product (Kumi and Daymond 2015). More than three quarters of the farmers of the country define themselves as the smallholder farmer, which means that the cocoa farm is owned and sustained by the farmers who live on that property. The high operational costs are taking a toll on the Ghanaian cocoa industry. The small cocoa farmers from Ghana are smuggling their cocoa to the Ivory Coast where the cocoa is selling fifty percent more (Laven and Boomsma 2012). The reasons for the success of the cocoa sector are the favorable prices. A range of the models estimate the sensitivity of the production supply to the farm gate prices discover that the small-scale cocoa manufacturers in Ghana and Nigeria have responded in a positive manner to the price incentives. There is liberalization of the domestic cocoa marketing is also a factor for the suc cess of the cocoa sector. The internal marketing has become competitive in nature. The new buying system puts a steadier stream of money in the hands of the producers that gives the farmers working capital to buy manual labor and other inputs when required. The Cocobod maintains the quality of the cocoa. The quality upholding comes at a cost that includes the cost of ensuring that the lower quality beans are not mixed into the ones that are prepared for export and the costs of management. The cocoa production is an agricultural manufacture activity that provides a high level of income in the unit field. The amount of the capital that is invested by the manufacturers is also high when compared to the other agricultural production due to the demand for labor force being high and intense. PESTLE Analysis Political- Ghana had fallen victim to bribery and lawlessness after its independence and hence despite being rich in the department of the resources it could not prosper much. There are two distinct parties in which looks into the matters of the productivity of the country. There is liberalization of the domestic cocoa marketing is also a factor for the success of the cocoa sector. An assortment of the models estimate the sensitivity of the production supply to the farm gate prices discover that the small-scale cocoa producers in Ghana and Nigeria have answered in a positive manner to the price incentives (Srdjevic, Bajcetic and Srdjevic 2012). Economic- the exports of cocoa, gold and oil are the major returns generating resources for Ghana and Nigeria. Cocoa and gold together account for around seventy percent of the exports from the country. However, due to the heavy reliance on these commodities, which have no value, addition to them makes the economy highly exposed and defenseless to the economic distresss. For instance if the prices of any of these commodities fall down then the economy will be hurt. The cocoa production reached an all high time between 2009 and 2010, but the reality was that the two respective countries were unable to put into operation the modern and the productive means of agriculture and the soil fertility that has been decreasing over the years. Social- To persuade the different ethnic groups to blend the government has implemented diverse policies. Nevertheless, there is poverty, the lack of education, diseases, vulnerable rural livelihoods and difficult labor conditions. Technological- The countries have shown tremendous growth in research and development and have spent a major portion of their Gross Domestic product on relevant activities. However, the science and technology needs to be developed. Legal- the government of Ghana and Nigeria has embarked vigorous campaigns in various forms to ensure a healthy workforce by the promotion of cocoa and its derivative products. For maintenance of the reputation of the high quality of the cocoa the Ghana Cocoa Board and the Quality Control Company Ltd. has been implemented for SPS related projects. Environmental- The World Wildlife Fund had made an alignment with the NGOs at Ghana and Nigeria to preserve the forests and the forest life. Analysis to the world's growing cocoa shortage Milton Hershey established Hersheys after his caramel company was a hit. In 1894, the company introduced Hersheys cocoa that was the very first product available to the public. Thus the brand of Hersheys was born. Hershey is a member of the World Cocoa Foundation. The company produces a variety of products that are chocolate and candy based (Beg et al. 2017). The company has been criticized for not having programs to ensure sustainable and ethical cocoa purchase (hersheys.com 2017). The company has none policies to produce cocoa that has been devoid of the use of labor misuse and they have refused to make available public information about its cocoa resources. As of August 24 the Hersheys Company it at the price of $105.52 with a volume of 2,298,937. The Hersheys Food Corporation holds the top position is the U.S. confectionary market. The name is identical with chocolate. The company operates in two main divisions, Hersheys Chocolate North America and Hershey International, the latt er exports the products of the firms to over 90 countries. The company is renowned for its major candy brands and also markets grocery products that are used for the purpose of baking. The global cocoa production has been down in the recent years due to handful of factors that also includes climate and crop failure while the demand has been on the rise. The cocoa bean shortage has resulted from the plagues and cost the farmers around $700 million in losses each year and is a concern for the Hersheys Chocolate, Mars and Incorporated who together produce three quarters of all the chocolate products that are sold in the United States each year. Five Forces Analysis Threat of New Entrants- The threat of the new entrants is low due to the existence of the economies of scale, difference in products, need for large capital requirements, lack of the distribution channels and regulations which are in place for the food manufacturers (E. Dobbs 2014). Bargaining power of the buyers- The number of large volume of the buyers and the buyers relatively low profits from the product increases the bargaining power of the buyers. It is low because of the differentiated products in the industry and the presence of the switching costs and the lack of backward integration. Bargaining power of the suppliers- The bargaining power of the suppliers is decreased due to the industry being an important consumer of the supplier group and the supplier does not pose a threat of forward integration. The bargaining authority is reasonable to high as this supplier group is concentrated. There are no substitute products and the importance of the supplier of the supplier product to the industry. Threat of substitute products and services- The threat of the substitutes are high in the cocoa industry. The industry has to compete with other alternate cooking flavors as vanilla and lemon. There should be competition in the retail arena also. The competition should also be with the non-chocolate snacks and other alternatives. Intensity of Rivalry among Competitors in an industry- The intensity of the opposition is high. There are equally balanced contenders that are slowly growing and have high storage and fixed costs and high exit barriers. These create the price wars, battles in advertising, new product lines and higher value of the customer service in the chocolate and cocoa industry. Conclusion Thereby, the report elaborates on a detailed examination and synopsis of the Ghana and Nigeria cocoa production situations inclusive of a PESTEL. The report also discusses the analysis of the Hershey group and the growing cocoa shortage with and the Five Forces Analysis. The big chocolate is a commerce term that is allocated to the multi-national chocolate food manufacturers. According to the self-described fair trade supporters, that includes the Ghanaian cooperative Kuapa Kokoo, the Big chocolate companies are Mondelez, which owns Cadbury, Mars, Nestle and the Hershey company.

The People Of The Kalahari Desert Essays - San People, Ergs

The People of the Kalahari Desert Part One Introduction, Location and Environment The people of the Kalahari desert are extraordinary people. For centuries their hunting and food gathering techniques have enabled them to survive in the difficult environment of the dry, hot and barren Kalahari desert. They are known as the Bushmen. Or the Kung or the Gikwe since Bushmen is rather discriminating because the "Bushmen" live among shrubs and trees and sand and such. The people of Kalahari Desert live in a dry bush desert in South-West Africa and western Bechuanaland, bordered in the North by Lake Ngami and the Okovngo River in the South by the Orange river and west by the Damera Hills. The Kalahari is there all low with sand dunes and great plains. A hostile country of thirst and heat. A country with scorpions, thorny bushes and of course sand as far as the eye can see and perpetual dust. In the hot months it the temperature goes up to 120 degrees Fahrenheit. In the months of winter, which are June and July, the winds from the Antarctic cold blow at night. But during the day it eventually rises up to around 80 degrees Fahrenheit and drops down in the evening. There are only three months of winter and these begin in December and in March the drought season starts and by August all the water holes that were made during the rainy season are dried up. It is not dead, the desert. There are boabab trees that give pear shaped fruits, flowers, and blossoms resembling gardenias. There are tall grasses. There are bushes flowering either red, white or violet flowers, tsama melons which very much look like watermelons and are the size of a small cantaloupe. There are also mogongo nuts that are very high in protein. When in season one person can eat as many as 400 nuts. These people who inhabit the dry, barren Kalahari have a hard life, so it seems... But, really, do they? Part two Food Resources and Technology Living in the hot sandy Kalahari might seem very difficult, even impossible. But if one knows the secrets of the desert. The desert will give you a living. The people of the Kalahari know these secrets. No fancy machinery necessary. No modern technology needed. Only simple handmade tools and weapons such as digging sticks, little axes, bows and arrows, small traps or snares, knives. Not to mention their senses and their wits. They poison the arrows so the game will die faster when hit. The poison is extracted from a certain grub. Great hunters know where the best place to shoot an animal so the poison will work best. Great hunters also know how to make the finest arrows. They also know all the habits of all the animals from the mice to the antelopes, they know what time of day that is best for hunting, too. There are quite a few food resources such as tsama melons, mongongo nuts, roots, berries, wildebeests, kudu, gemsbok, antelopes, steenbok, porcupines, elands, small animals like the mongoose and the chicken fowl, birds- even babies-, wild boars as well as honey from the bees. And of course there are a couple of temporary and permanent water holes around. They use digging sticks to dig up roots, they gather tsama melons, mongongo nuts, and berries. They hunt game with bows and arrows and spears on foot. They cook mongongo nuts in hot ashes, eat the entire animal from the hide-which they work into leather sometimes- to the marrow inside the bones. Of course this might seem like a lot a meat since the game is plentiful but really 80 percent of their diet is vegetables. Sometimes when cooking meat they cook it in the rind of the tsama melon with the liquid still inside and it makes a stew. The people are smart and know their land very well. Therefore as long as they know the secrets the hot desert holds, the desert will give them a living and they'll never go hungry. Part three Social System and Leisure The size of the groups vary from 20 to 100 people or even 200 people per group. The groups have to be small or else moving from place to place will be extremely difficult. The roll of a man is to hunt and gather honey from the bees. The roll of the woman is to gather and dig for roots and taste them to see
