The center results of the organization are partitioned into three: mens, womens and childrens garments. On to it, they have a wide scope of attire and embellishments, for example, purses, adornments and footwear. Zaras capacity to dispatch and item and make it accessible in the market inside about fourteen days made it prestigious in the market, as different contenders took a base time of a half year for the activity (zara official web, 2017). A SWOT investigation alongside four business vital examination is done in the report for an away from of the organization and its condition. Three vital issues have been called attention to in the report with suggestions for likely arrangement (Zara Official Website, 2017).

Their solid flexibly chain and circulation channel assumes an imperative job in their activity and fills in as a quality. They utilize a vertically incorporated framework with capacity to reproduce design. Their differentiated scope of items isolates them from other comparative organizations. Additionally, their remarks and supposition areas in each stores esteem their clients conclusion which makes them interesting (zara Swot, 2017). Shortcoming Zara has a unified creation, which cause them a gigantic work cost. This is a major disadvantage of the organization that should be cared for. Another shortcoming of the organization is the low interest in the ad. Their internet business segment is feeble contrasted with the block and divider stores. The utilization of their euro-driven model additionally fills in as soft spot for their brands as they are working in a worldwide level. In conclusion, Zara International has been labeled as imitators which present danger to their picture. They have to improve their architect segment to defeat the reality (Bull et al., 2016).

Vital Analysis So as to shape a vital arrangement for the eventual fate of the organization for guaranteeing the settled notoriety and the continuous achievement, a key examination of the organization is fundamental. With the end goal of the report, ID and assessment of four business systems are introduced. Corporate Strategy Corporate procedure or also called corporate level technique is the blend of key choices that a business takes for the general development of the organization. This system impacts the whole association. Zara has quality of getting any item showcase inside about fourteen days which is a novel selling process that necessities further misuse. Individuals everywhere throughout the world have a propensity of getting items than other which is a fundamental point that will enhance this thought of bringing items before others. Another point Zara centers around which helped them making their progress is their proficient gracefully chain. Both the methodologies needs higher creation cost. Subsequently, Zara needs to hold their value position, which will empower them to draw clients for new design items which will guarantee the constant income for the organization (Furrer, 2016).

To keep up the position, it is vital for the organization to concentrate on the angle and keep up a nonstop up-degree in the items. They have to think about the expense of the creation while adjusting the structures. Then again, certain product offerings needs more concentration to increase new open doors for improving the flexibly chain and furthermore keep up the high chain advertise. Companys quick dynamic flexibly chain is the focal point of this which should be cared for. As their systems are notable to the rivals in the market, it is impor tant for Zara International for building up the chain with more effectiveness. The innovation assumes a fundamental job in keeping up a quick gracefully chain which is building up each second. To stay aware of the innovation and keep up the quick flexibly, Zara needs to concentrate on innovation and its efficiencies which require an appropriate business level system (Hill, Jones Schilling, 2014: Drnevich Croson, 2013). Future Strategies As a quick pattern style organization, Zara International should concentrate on the development. Consistent structure monetary weight put Zara into the circumstance where they have to chop down the creation cost. The main way it is feasible for the organization is to underline in assembling territory where new creative plans can make light of the job for cutting the creation cost. Along these lines, the organization will have the option to accomplish the objective without trading off their morals (Caro, 2012). The board Strategy This degree of procedure centers around the improvement of the adequacy of activity inside the organization. The reason for this is to consider its to be choices as explicit to an utilitarian zone of the associations. The organization is well known for quick design. The organization should concentrate on the re-appropriating. This may prompted question the quality administration and worker relationship the board. It can likewise cause strategy making issues. It will require new thoughts and presentation on new plans in item. It will in the long run produce new culture based items which can expand the interest. In any case, it will assist the organization with managing their conveyance increasingly proficient way. Something else which must be considered is the eco agreeable methodology. As the contenders are at the companys tail in the eco neighborly crucial, needs to set another benchmark for the reason that can stay with the well ahead (Zara contextual investigation, 2017). Vital Issues Faced by the Company One of the major vital issues of Zara worldwide is the showcasing as they dont promote through conventional media. Just a chose scarcely any business embraces this procedure and Zara is one of them. In any case, it doesn't imply that the business has caught the greatest market. The business needs commercial to get to more chances. Being an incorporated organization, Zara global has a general monetary technique for all the nation. Be that as it may, the valuing methodology of the organization needs to shift contingent upon the countrys economy and the obligations the organization needs to pay in that nation for working together. Subsequently, there is an obvious requirement for a superior evaluating procedure for each nation. On to it, they need proficient planners to deliver cost productive apparel to manage the financial weight all around. The plans that are accessible at Zara are European based remembering the European condition which should be changed. For instance, Asian nations need progressively assorted attire dependent on their climate. Be that as it may, there are just ordinary fabrics accessible at Zara Stores far and wide. Proposals To start with, the organization should begin thinking all inclusive and consider the way of life of the nation they are managing in. The organization supplies the design pieces of clothing that are lauded by the western nations. The flexibly of culture based style will expand the interest. The moral issues that are looked by the organization should be managed. At long last, the clients recommendations ought to be given most extreme need. The negative recommendations ought to be quickly managed to hold their likings toward their item as the clients fulfillment ought to be of prime enthusiasm to holdthe present client devotion. End The organization is a settled worldwide design retailer. They are acclaimed for their quick style and getting the item stores inside about fourteen days of dispatch. This is simply the territory where the organization recognizes from other comparative organizations that additionally requiring little to no effort. The SWOT investigation that has been introduced in the report recognizes a few shortcomings and dangers that should be joined in. A few issues are recognized in business procedures, for example, widespread estimating methodology that should be changed so as to proceed with their uprising in the business. One of the significant issues is the valuing and the financial weight that has been recognized under vital business gives needs an appropriate arrangement as notice in the report. Last yet not the least, the proposal that are made in the report ought to be altogether checked and actualized. References Anwar, S. T. (2017).

Why So Serious

Why So Serious Its been a while since Ive had time to sit down for a long period of time and blog. I promise I have a good reason though! Most people at MIT have these Hell weeks where there are lots of tests and projects due. Ive honestly felt like Ive had a Hell month. But dont worry, Im Still Alive. Although I didnt actually type out many of my ideas, I was still thinking of the things I would write for all of you out there who read the blogs. Thinking of all the things I would say post-decision time. It was a tough process but I hope it leaves some of you inspired. If youre wondering what its like to go to MIT, its pretty much like this. Or this. Sometimes MIT feels like one intense workout on a treadmill. The treadmill just keeps going and going. Youre trying to reach the controls to slow down, but theyre just out of reach. You fall flat on your face or completely screw up and end up tearing apart the treadmill Youre only human after all. Eventually a routine sets in. You have problem set after problem set, then a week of tests and projects, and then theres that whole thing about living (like eating, sleeping, and exercising?). MIT isnt all fun and games. There are times when youve just had enough. You give up. You break down. Youre worn out, stretched thin, and feeling a little downhearted. IHTFP right? Yet every time I feel like Im in that situation, I keep running. I tell myself its all worth it. I take it all in and try to just do it. Sometimes I fail. Sometimes I survive. The constant rollercoaster is exhausting. I keep thinking perhaps 5 classes and a UROP are too much But heck, Ive learned so much about myself in the process. After all, its only when were pushed to our limits, that we can understand where they fall. Over this long and heart wrenching month, Ive ultimately come to the realization that Im just taking myself too seriously. Which begs the question Honestly, its so easy to get sucked into the MIT mindset (or as I like to think of it, the Jedi mind tricks). You start to feel like you need to do everything and plan every element of your four years out. But really, theres no rush to do it all now. Its okay to jog instead of run. Keep up at a steady pace. Punt a little more now and then. Tackle the issues as they arise. Enjoy the little things in life. Whether that be getting to the T stop right as the T pulls in, walking up to Mass Ave right as the crosswalk changes to walk, or taking in the occasionally beautiful weather on the green grass in Killian. (Photo credit to the wonderful Preeti 15) Most importantly though, remember the BIG picture. At the end of the day, it doesnt matter whether you didnt get an A on that test. It doesnt matter if you cant get the last 2-3 questions on the problem set. It doesnt matter if your project isnt 100% perfect. What does matter is what you take away from the experience. Be that a degree, a life lesson, a useful skill, or a new friend. Remember: We cannot change the cards we are dealt, just how we play the hand. -Randy Pausch So no matter where life ends up taking you, make the most of it. There are many incredible education institutions out there. True, your experience will not be the same everywhere. But this doesnt mean your experiences will not be enjoyable and meaningful. Youre the only determinant of that. Get involved. Get inspired. Make a difference. Class of 2016, youre in for the journey of a lifetime. Get ready to embrace it. Much love, A reluctantly, soon-to-be sophomore

Social Cultural Or Environmental Impact Caused By Tourism Tourism Essay Essay Example

Social Cultural Or Environmental Impact Caused By Tourism Tourism Essay Essay Introduction Having developed some of the universe s most unthinkable attractive forces, like a ski resort amidst a desert and an archipelago resembling the map of the Earth, Dubai, a metropolis in the United Arab Emirates, has emerged as a alone touristry finish in the past two decennaries ( Henderson, 2006 ) . Dubai is a coastal metropolis, which offers sand, sea, and Sun, with conservative Islamic and Arab traditions. Even though the rapid rise in the touristry sector has led to rapid growing of the economic system, this growing is paired with assorted environmental every bit good as societal and cultural impacts. The undermentioned essay discusses these impacts and what the ground behind these impacts is. Subsequently, the impression of sustainable touristry is discussed and how Dubai can keep sustainability of touristry every bit good as societal, cultural, and environmental values.

Emirates is listed amongst the universe s most epicurean air hoses ( Verdonck, 2007 ) . All flights are via Dubai, which means one traveling by Emirates must halt in Dubai foremost. Every unit of currency spent in Dubai benefits its economic system. Although good to the economic system and touristry industry, air travel is a prima factor of air pollution. Dubai, since the mid 1990 s, has been practising rapid touristry focused development ( Rockwell, 2006 ) . This is non merely the building of hotels, but besides of state-of-the art promenades and edifices, all of which are meant to pull tourers and international investing. The building in Dubai additions by 34 % per annum ( Heyer, 2008 ) , and is utilizing a 3rd of the universe s Cranes to construct 100s of skyscrapers ( Clarke, 2004 ) , most of which can be attributed to the metropolis s willingness to increase touristry. Construction once more has inauspicious environmental impacts. A batch of this building for illustration that of the thenar shaped island called The Palm Jumeirah requires a method of dredging and re-depositing where stones are collected from the underside of the sea and deposited where wanted. This unluckily has lead to the one time crystal clear Waterss to be filled with silt. Resultantly, given the suicidal nature of touristry, plunging partisans have started looking for other countries with greater visibleness in H2O ( Butler, 2005 ) . The above mentioned method of building has besides destroyed marine life. For illustration, the Arabian Gulf s 2nd most bio-diverse Marine system was handed over to the building company Nakheel to construct another thenar shaped island on. Consequently because of such Acts of the Apostless, the coral reefs and sea grass have been buried and killed under stone sedimentations. The oyster beds are known to hold been buried two inches deep. Construction companies mention that they will construct unreal constructions under H2O, but ecologists argue that these new unreal constructions will non back up the original native species of the country, but they may pull foreign, destructive species ( Butler, 2005 ) . The touristry lead building in the sea has lead to many breaks in the moving ridge currents. The beaches of Dubai have therefore started to gnaw off. Tourism, even though indirectly, has started to bit by bit decrease one of the grounds that it exists ( Butler, 2005 ) . Other illustrations of touristry attractive forces in Dubai include a Tiger Wood s golf class, which imported 30,000 mature trees, an 820 square meter refrigerated swimming pool and an unnaturally chilled beach to maintain the sand cool ( Hickman, 2008 ) . Not to advert, Dubai, as mentioned by the United Nations, is the universe s most water-imperilled country. Enormous degrees of Energy and desalinated H2O, which finally requires even more energy, have to be used to keep such attractive forces. All of Dubai s edifices, such as hotels and shopping promenades, are air-conditioned which means that more electricity is needed and the emanation of nursery gases exceeds that of the universe norm greatly. Dubai s emanation of nursery gases is 33.6 metric dozenss per capita, whereas the universe norm is at merely 3.7 metric dozenss per capita ( Saadeh, 2007 ) . This non merely negatively affects Dubai itself, but besides affects the remainder of the universe. A hotel in Dubai produces appr oximately dual the C emanations as compared to a European hotel ( eTurboNews, 2009 ) . Many conservationists worldwide can perchance reason why the other states of the universe must endure because of what is go oning in Dubai. In a United Nations clime talk, UAE s curate for Environment and Water spoke of atomic power to desalt the H2O which would hold even worse affects on the environment ( Hickman, 2008 ) . Therefore one can easy construe that Dubai s touristry does non merely have negative impacts on its ain environment but perchance that of the universe. SOCIO-CULTURAL IMPACTS Tourism s impacts in Dubai are non restricted to the environment. The occupants, merely of which a really little figure are local citizens, have besides had to travel through some major alterations in a really short period of clip. As mentioned earlier, Dubai has one the most successful air hoses in the universe, and the Dubai Airport is obviously rather busy. The airdrome is located in the chief metropolis as seen from the map below: Beginning: Google Maps The airdrome operates 24 hours and therefore it is easy assumable that the noise pollution is at high degree. This affects all the occupants in the environing countries. There is a major clang between western civilization and the Islamic civilization that prevails in Dubai and its milieus. To a westerner the thought of traveling to a beach to the full clothed may look rather unpointed and hence tourers wear swimming garb at beaches. Dubai has faced some major jobs in this respect. The mean labour working category of Dubai is largely of work forces from the Indian subcontinent where it is rather uncommon to see adult females on beaches have oning Bikini. For the above mentioned grounds, work forces of the working category had started to garner at beaches to gaze at adult females and snap them. There would be occasional cases when they would forcefully experience adult females in H2O. The Dubai constabularies have about arrested 500 work forces because of this ( Fattah, 2006 ) . Dubai s western positions are non usually accepted by the conservativists of the metropolis. Regardless of that, the swayers have made a move frontward. Dubai has tried to suit western civilization which in the long-run could perchance stop in the loss of Dubai s ain civilization. In the past few old ages, tardily dark parties every bit good as alcoholic drinks have become really popular and common, something which is non appreciated in the Arab civilization. Dubai has legion different sorts of cabarets and bars to offer to its tourer population ( Expat Forum, 2009 ) , which could perchance alter Dubai s ain population, and would be most influential on the young person. A New Year s Eve party held on The Palm island had to a great extent intoxicated people dancing on the beaches in the nude ( www.EscapeArtisit.com ) . Possibly one can state that the people of Dubai have already started to lose their cultural, spiritual, and societal duties as a direct consequence of touristry. Sexual activity touristry has besides vastly affected Dubai. The Dubai Information Site docudrama clearly shows with a concealed camera that harlotry is merely illegal on paper and is literally supervised by jurisprudence implementing governments and besides suggests that the authorities and secret bureaus know all about it ( www.Dubai-Information-Site.com ) . One possible ground thinkable is that Dubai really wants to pull sex tourers so that money keeps pouring into the economic system, but this theory is non evidenced. In some cases Dubai has been compared with Morocco and the Philippines at sex touristry degree ( www.Dubai-information-site.com ) . Streets of Dubai are filled with easy identifiable cocottes, possibly most of these adult females are at that place to pull local clients but many besides end up pulling tourers. The more expensive cocottes work at 5 star hotels where evidently tourists besides stay, doing the being of sex touristry even more solid and credible. In an i nterview with a cocotte, she said Most of my clients are Australian, Canadian, and local work forces ( Robson, 2009 ) . An tremendous addition in harlotry, particularly when a big figure are tourers are the clients, puts occupants of Dubai at hazard of sexually transmitted diseases such as Syphilis and HIV. What 1 must see is, is Dubai still a topographic point where 1 can raise kids with preexistent societal and cultural values? THE MAIN REASONS FOR NEGATIVE IMPACTS What has been the chief ground for all these socio-cultural and environmental alterations? As mentioned earlier, the authorities, or swayers, because Dubai is non a democracy, want to assist the economic system by presenting tourers. Dubai took a political stance in the mid 1990 s that because the oil was traveling to acquire dog-tired they should exchange their focal point towards touristry. Investings in Dubai are largely international and most of the flats in the residential skyscrapers built were sold to really rich aliens. The prince of Monaco besides bought an island in the archipelago The World ( Clarke, 2006 ) . Therefore the second place phenomena is besides one which helps increase touristry in Dubai, and therefore touristry impacts on Dubai even more greatly, as tourers will see once more and once more. It was in this stance that Dubai s swayers besides decided to do many tourer attractive forces including the assorted hotels and bars. The Chief executive officer of Duba iland, the universe s largest subject park, is known to hold said that we want to do Dubai Venice of the Middle East with streamlined H2O canals ( Heyer, 2008 ) , which once more is inordinate usage of H2O in a part where H2O is a cherished resource. It was investings in such strategies that were followed by lay waste toing environmental impacts. Not merely is the running and maintaining of such attractive forces unhealthy for the environment, but it is besides the building which greatly affects it. The authorities of Dubai has been rather grim in the building of these attractive forces, so much that the already few conservationist groups and NGOs in Dubai had to be made soundless and were non allowed to interfere at all ( Hickman, 2008 ) . It would non hold been hard hushing these groups as Dubai is non a democracy system. NGOs and conservationists merely occupation is to educate school pupils about recycling ( Hickman, 2008 ) . The building company Nakheel, responsible for the building of the ill-famed Palm Islands, the land reclaimed The World and many other environmentally harmful undertakings is owned by the swayer of Dubai himself, His Highness Sheikh Mohammed Bin Rashid Al Makhtoum ( Clarke, 2006 ) . Therefore we can easy state that the ground for the impacts is possibly rigorous attachment to political and economic policy. Quite late, given the 2008 economic slack, Dubai has started confronting economic jobs every bit good. In the recession, there was a considerable bead in touristry in Dubai ( Walid, 2009 ) . Unfortunately, the whole intent for which Dubai had to endure through socio-cultural and environmental impacts may be excessively volatile. Any state should neer be excessively dependent on any one sector of the economic system, particularly a suicidal one like touristry. IS SUSTAINABLE TOURISM POSSIBLE? Sustainable touristry as defined by the United Nation World Tourism Organization ( UNWTO ) is Tourism that takes full history of its current and future economic, societal and environmental impacts, turn toing the demands of visitants, the industry, the environment and host communities. ( Bartlett, 2007 ) First, the inauspicious effects of touristry are lessened if the growing in tourer population is comparatively slow ( Cooper et Al, 2008 ) . This was non the instance for Dubai. Dubai has seen an tremendous growing in its touristry over the past 15 old ages. Therefore the impacts on the environment and the people have been greater than they could hold been. The occupants of Dubai did non hold much clip to turn accustomed to the ways of the tourers. Like London and New York, where occupants are already accustomed to an urban manner of life with the presence of tourers ( Cooper et Al, 2008 ) , Dubai s occupants are non. Dubai has already started to implement sustainable touristry ( Mustafa, 2007 ) . A recent enterprise by the earlier mentioned Nakheel is called Blue Communities ( www.BlueCommunities.org ) . For illustration, at the Palm Island they have introduced a new air conditioning system which reduces energy use by 35 % . Such issues should non merely be addressed by one building company, but all building companies. Dubai s authorities is strong plenty to implement such Torahs that will minimise the harm to the environment. Some hotels in Dubai have besides started to take the environmental issues and hence their C emanations earnestly. They have taken stairss towards diminishing their environmental costs and recognize the fiscal benefits that could be received by traveling green ( eTurboNews, 2005 ) . Such enterprises can be really expensive to Dubai can utilize the illustration of Egypt, which has similar societal and cultural values and even possibly related environmental issues. When the Red Sea started to turn as a tourer finish, the authorities took a similar attack to that of Dubai s, based on building of hotels. Subsequently, they implemented direction programs and introduced a Sensitivity Map which rates resources in footings of their resiliency to the impacts of usage ( Bartlett, 2007 ) . Furthermore, Egyptian governments have started supplying inducements to be more sustainable ( Bartlett, 2007 ) . Dubai could take a similar attack. After a instance of two British subjects holding sexual intercourse on a household beach, governments have introduced some new guidelines for occupants and tourers likewise. Now, loud music, curse, caressing, have oning skirts of inappropriate length, and even keeping custodies and embracing in populace has been banned ( www.News.com.au, 2009 ) . Alternatively of being on the utmost terminal and censoring the activities mentioned above, which are quite common in the tourers ain states, Dubai can take a similar encourage, non deter attack ( Bartlett, 2007 ) . Dubai can advert the Arab and Muslim civilization in any booklets and advertizements of the finish ; otherwise, if tourers hear about such prohibitions and restriction, they might desire to see an alternate finish. The same encouraging attack as that of Egypt can be taken towards building companies, in which fiscal assets could be provided. Similarly, Emirates Airline could go on to buy the new A-380 aircrafts as they are more environmentally friendly. Research shows that 45 % British tourers are willing to pass more on holiday if environmental amendss can be reversed, 67 % Americans think it is of import that they do non damage the finishs they visit, and 69 % Danish tourers are willing to pay more for eco-labelled hotels ( Bartlett, 2007 ) . All three states above generate high Numberss of tourers. Thus authorities functionaries in Dubai can presume that if they want to fund in environmentally friendly activities, this will potentially pull more tourers. Dubai s authorities could perchance take another measure towards sustainability. Random occupants could be drafted, at their will, in big groups to be a portion of a panel, similar to a selling house s consumer panel, where they could be asked to notice on any new developments that have been thought of. This manner the normally held positions of the community will be known and because a random outlining system is used many members of the community will experience more of import and therefore less immune to alterations. The execution of such a system will be difficult and boring. It may besides rather dearly-won for the authorities. Eco-tourism can be practiced although in a really alone manner. Eco-tourism normally trades with of course beautiful countries, but could besides perchance affect the alone civilization and traditions of a part ( Bartlett, 2007 ) . Dubai can publicize the rich Arabic traditions that prevail in the part and demo how cultural and environmental values are in the metropolis s nucleus. Eco-tourism would be hard because of the ill-famed impacts on the local and planetary environment and the alterations that have already occurred in its occupants. Still, it is a really distant possibility in the long-run. If achieved, Dubai may be a possible eco-tourism finish which would ironically pull multitudes. To accomplish sustainable touristry, the differences between the occupants and tourers must be reduced ( Cooper et Al, 2008 ) . If Dubai s people were to alter and go like westerners, this would once more stop up in loss of individuality and alterations in civilization. Alternatively, skillfully designed plans for schools and likewise designed advertizements aimed at Dubai s grownup population could learn them about the positive effects of touristry and adaptability. On the other manus, advertizements aimed at tourers from different states could be made cognizant of Dubai s cultural and spiritual values. In the instance of Dubai specifically, there should be purposes made at cut downing harlotry to do the societal state of affairs better. By doing police governments more efficient and taking a stance to halt human trafficking at the airdrome, so no cocottes enter. For Dubai s touristry to turn sustainably a few of the mentioned methods must be used so that the involvements of the people, tourers, and environment are satisfied, all the while the touristry industry thrives and grows. Although this is hard as there is a clear tradeoff between certain factors, for illustration building of attractive forces leads to an addition in touristry but harms the environment. Therefore Dubai s touristry sector needs a skillfully devised program to pattern sustainable touristry. It besides needs the apprehension that environmental and societal systems are non two distinguishable theoretical simple systems, but are one complex existent system and that worlds are besides a portion of the environment. This system is hence ever germinating and altering with uncertainnesss and remains stable merely for a short period of clip ( Fyall et al, 2005 ) . As the system evolves, Dubai s programs of sustainable touristry will besides hold to alter, because the involvement s of all stakeholders are different at all times. Decision Dubai must affect and alter the behavior of all the stakeholders involved such as tourers, occupants, conservationists, and authorities functionaries. Merely so can sustainable touristry and development be achieved and the negative impacts of touristry reduced.

Bob Dylan essays

Bob Dylan essays Thesis Statement: Bob Dylans life affected his writing and contributed to the development of his music. Bob Dylan was recognized by his poetry and song writing. He usually wrote songs about protesting and religious themes. Bob Dylan is unquestiably one of the most influential figures in the history of popular music. He is he writer of scores of classic songs and is generally regarded as the man who brought literacy to rock lyrics. Although the theme of Bob Dylans work is depressing, it is necessary to consider how the events Bob Dylan was born as Robert Allen Zimmerman in Duluth Minnesota on the date of May 24th 1941. His father Abraham owned an appliance store in Minnesotas Messabi Range. Robert was 6 years old, they moved to a small town called Hibbing were he went to school. By the time he was ten years old he was writing poems and had taught himself to play guitar. After he graduated high school in the early 1959 Dylan found himself playing folk music. This is also the time he began to write his legendary folk songs. After graduation from High School in 1959, he left for Minneapolis to follow his studies at the University of Minnesota. Here his love for contemporary rock and roll came up and he listened to endless music by Hank Williams, Robert Johnson and Woody Guthrie. His passion for music was so huge that he began skipping classes and also began to play his music at small local nightspots. In 1961, the 20 year old Bob Dylan dropped out of college alleging lack of interest in career. In this time, he adopted the name Bob Dylan inspired in a poet called Dylan Thomas. After leaving college, Dylan broke up with longtime girlfriend Suze Rotolo , and got involved with the world famous folk singer-songwriter Joan Baez. Both fed off of each other with Baez using Dylan's mu ...

Definition and Examples of Lexicography

Definition and Examples of Lexicography Lexicography is the process of writing, editing, and/or compiling a dictionary.  An author or editor of a dictionary is called a lexicographer. The processes involved in the compilation and implementation of digital dictionaries (such as Merriam-Webster Online)  is known as  e-lexicography. The fundamental difference between lexicography and linguistics, says Sven Tarp, is that they have two completely different subject fields: The subject field of linguistics is language, whereas the subject field of lexicography is dictionaries and lexicographic works in general (Beyond Lexicography in  Lexicography at a Crossroads, 2009).In 1971, historical linguist and lexicographer Ladislav Zgusta published the first major international handbook on lexicography, Manual of Lexicography, which remains the standard text in the field. Etymology: From the Greek, word write Pronunciation: LEK-si-KOG-ra-fee Beginnings of English Lexicography The beginnings of English lexicography go back to the Old English period . . .. The language of the Roman Church was Latin; its priests and monks needed to be competent in Latin in order to conduct services and to read the Bible . . .. As English monks studied these Latin manuscripts, they would sometimes write the English translation above (or below) a Latin word in the text, to help their own learning, and as a guide to subsequent readers. These one-word translations, written between the lines of a manuscript, are called interlinear glosses; they are seen as the beginnings of (bilingual) lexicography. (Howard Jackson, Lexicography: An Introduction. Routledge, 2002) Samuel Johnson (1709-1784) and English Lexicography I am not yet so lost in lexicography, as to forget that words are the daughters of earth and that things are the sons of heaven.(Samuel Johnson)[Samuel] Johnson was not only innovative in his use of 114,000 citations to prove his definitions and the usage of words and connotations. He also noted the author who had first used a word or collocation and who had last used an obsolete word. He also took the liberty of adding prescriptive commentaries whenever there was doubt about usage.(Piet Van van Sterkenburg, A Practical Guide to Lexicography. John Benjamins, 2003) English Lexicography in the 20th Century In the English language area, the lexical orientation has long remained historical. The first edition of the Concise Oxford Dictionary, by H.W. and F.G. Fowler, dates from 1911 and leans heavily on [James] Murrays New English Dictionary on Historical Principles [later renamed the Oxford English Dictionary]. It was also due to the fact that the first supplement to the OED was published in 1933 and the second was in preparation from 1950 onwards, to be published in four thick volumes under the general editorship of Robert Burchfield. Incidentally, that supplement did include swear words, sexual terms, colloquial speech etc.Innovations in the English lexicography were to be seen in the dictionaries by Longman and Collins, based on contemporary corpora of electronic texts and anchored entirely in a database structure. . . .In 1988, the first edition of the OED was made available on CD-ROM and the second edition in 1992.(Piet van Sterkenburg, The Dictionary: Definition and History. A Prac tical Guide to Lexicography, edited by Piet Van Sterkenburg. John Benjamins, 2003) Crowdsourcing and Contemporary Lexicography Websites such as those for Urban Dictionary and Wiktionary . . . offer what is known as bottoms include Twittersphere, sexting, cyberstalking and captcha. . . . Such shout-outs are the antithesis of traditional lexicography. . . . If the dictionary-maker is a humble archivist while the lexicon is being created, they become a deityor at least a cut-rate Mosesonce it appears and becomes a source of supposedly trustworthy information. . . .Letting in the street will end no worlds but will it improve the quality of dictionaries? Form as ever faces off content. The form can be democratic as all hell, but in lexicon-land, surely the content is what matters. . . .Reference should be online. The opportunities for presentation, for breadth of information and for sophisticated searches that would be impossible in a print dictionary are too good to miss. But if reference is to remain useful then it cannot become amateur hour. (Jonathon Green, Dictionaries Are Not Democratic. The Observer, September 13, 2012) The Lighter Side of Lexicography LEXICOGRAPHER, n. A pestilent fellow who, under the pretense of recording some particular stage in the development of a language, does what he can to arrest its growth, stiffen its flexibility and mechanize its methods.

Project Essay Example | Topics and Well Written Essays - 1000 words

Project - Essay Example It is also important to note that some motors produce immense output power, but cannot be efficient enough. It is under such conditions that people make use of H Bridge in the efficient control of the Motors’ direction. Project Fundamentals An H-bridge circuit refers to a power circuit that is electric, and used in the control of electric motors like DC motors used in automotive applications. The H-bridge functions in controlling the direction and speed of the motor by allowing a limited amount of current to flow in the motor through the right direction (Barrett, 2012). It is made up of four MOSFETs, which are under the control of control signals of the (PWM) Pulse Width Modulation. The original design of the DC motor control incorporates Multisim LabVIEW co-simulation that permits the performance of the entire system to be authenticated on the desktop. The motor has such parameters as inductance, the load weight, and armature resistance for accurate verification of the result s of the performance. The use of a multisim-labVIEW co-simulation ensures that one shall not have to digital and analog systems separately. During the implementation stage of the model, the circuitry of the analog can be transferred for photocopying to the Ultiboard. Such a transition between the Ultiboard and Multisim makes sure that there is a precise convey of simulated designs. The graphical code of control is moved to a Single Board Rio 9695 target. This is usually an acquisition device and an embedded control that puts together a FPGA that is user-reconfigurable, a real time processor, and input or output of printed circuit board. The four MOSFETs needed in designing a H-bridge can be demonstrated with the diagram below. Two of the MOSEFETs should be of P channel (IRF9540N), while the other two should be of N channel (IRF540N). They should be designed in such a way that the motor’s rotation is controlled through an on-off-on switch. The motor’s closed-loop contro l starts through inputs that are user-defined such as the necessary step size and speed. This message is resent to the Multisim design through the co-simulation terminals. Negotiations between labVIEW and Muiltisim occur as a guarantee in conversation and accuracy for both sides. In case of abrupt drops or peaks in Multisim, negotiation in time-step allows Multisim to alter the available time-step to view the drops and peaks. A point by point model between digital systems and analog circuits results to an advanced system both in accuracy and behavior. Once the verification of the system design has been made with Multisim and labVIEW co-simulation, the complete circuit can be moved to Ultiboard for routing and layout. List of Components The list of components used in the circuit includes: MOSFET P Channel (IRF9540N) – 2 MOSFET N Channel (IRF540N) – 2 Motor – DC 6 volts Battery – 9 volts Switch – 1 Connecting Wires and Strip Board Controlling the Mot or The control of the motor is done through the two ways switch connected to Q1 and Q3 of the circuit. If a signal is sent to Q1the motor is stimulated to move in a forward direction, while on the other hand, if a signal is sent to q3 the motor is stimulated run in a reverse direction. It is never possible to sent signals to both Q1 and Q3at the same time because of the use of on off on switch. This can be summarized using the following table: Q1 Q3 Stop 0

Leadership assignment 6 Example | Topics and Well Written Essays - 250 words

Leadership 6 - Assignment Example This paper looks at how I manage my leadership practice as the chairman of the class discussion group as well as in singing group in church, the barriers and strategies I use to overcome such barriers. Last week when we came together as group members, fifteen of us, to discuss about class assignments and other contentious class lessons, I found myself spearheading the discussion as I usually do, the act that saw me chosen as the group leader unanimously by all the other fourteen members. I helped in interpreting the meaning of the assignments thus making the topic understandable to everybody. I went ahead to create alignment in the objectives and strategies that we would use as we handle the discussion. As my usual practice, I went ahead to build commitment and optimism in every member making them believe that the task was such an easy one. I urged the members to trust in each other since mutual trust among the members make them work freely with others without any fear that could be brought by mistrust thus enhancing cooperation. I always urge my members that people should know us as ‘’GROUP 1’’ i.e. collective identity other than being known as individu al members of the group which would make other members feel up while others feel down. As we went on with the discussion, I made sure that all activities were well organized and coordinated. To encourage and facilitate collective learning, I ensured equity participation from all the group members and thorough explanation done to weak members of the group so that they could catch up with others. I ensured necessary resources required for the discussion are availed in the form of textbooks, charts and writing materials and even organized with one of the lecturers to come and help us with certain areas where we needed more explanation. In a way to develop and empower every member, I ensured

The Lost Phoebe Analysis

The Lost Phoebe Analysis In the story of The Lost Phoebe, Theodore Dreiser writes a story about a man and his wife. Dreiser tells so much about the mans childhood and early adulthood because he was showing the reader how Henry Reifsneider was doomed to suffer in isolation at the end of his life. The man, Henry Reifsneider, had lived with someone all his life. He lived with his parents until he fell in love. When Henry fell in love, and decided to get married, his parents invited his bride-to-be to live with him. Henry married Phoebe when he was just twenty-one years old and .had been married for forty-eight years. He also continued to live with his parents until they passed away ten years after his marriage to Phoebe. Their death probably would have been the first time that he had to deal with the idea of people, in which he cared a great deal for, leaving his life forever. Dreiser does not mention anything about other people, such as grandparents so it would be unknown to the reader if he ever knew them. He lived with Phoebe for forty-eight years until her death, this was, probably the worst goodbye this man had ever had to endure. Forty eight years of marriage yielded seven children. Three of his children had passed away, further setting the scene for this poor mans isolation. The rest of these children had moved away to other cities, some other states. It seems as if there was no time in his life that he was alone until the death of his wife. Phoebe became sick when she was sixty-four years old. The disease she came down with might have been curable if it was not for her age. He followed her body to her resting place consumed with grief and uncertain as to what he should do next, or what the rest of his days would bring. Even though his children and friends asked him to come and stay with him and let them take care of him, he was so set in his ways that he would not dare to budge. The next couple of months were spent dwelling on her death. He will not leave his home and could not care less if there were visitors to the home. He knows that it will soon be his turn to die and it seems, to me anyway, that he welcomed death. He could again be with his love only if he passed away. Henry gradually started to put his wifes things away, but five months after her death a change had begun in him and his isolation had gotten the better of him. Late one night, after a particularly restless night, shapes in his house began to take the shape of his wife. Of course, when he went to her he found that it was all in his imagination. Shortly, he thought he saw her in the yard. When his Phoebe was alive he would accuse her of moving his things. She would always have the same come back of telling him that if he continued to accuse her of these things that she was going to leave him. She would also claim that he would never find her if she did decide to leave. It did not take long for his mess up mind to think that she had, in fact, made good on his promises. Since he had packed up some of her things, it gave his dementia the reasoning it needed to support his claim. In his mind, he had not packed her things away, she had packed her things. The first place he went to look for his wife was at her friends house, Mrs. Race. He told her friend that he and his Phoebe had gotten in an argument and had left in the middle of the night. She, of course, realizes, that he has lost his mind without his dear Phoebe and tries to go along with his mad fantasy, so that she could keep him there until someone could get there to help this poor man. He would not stay any longer. He was a man on a mission; he would find her and bring her home. He walked around all day asking anyone who would listen if they had seen his wife and telling them the same story. Someone did call the authorities, but the authorities dismissed him as being a harmless old man, who would be in less danger to himself if they had left him to walk the miles he did ever day than if they put him in some sort of hospital or nursing home. Most of the county knew who he was and pitied him. His neighbors would do their best to take care of him, feed him and whatever they can do for him. As the years go by, Henry loses his mind more and more. Dreiser skips ahead three years. In this three years Henry has spent the entire day, every day walking miles and miles looking for his dead wife. His mind is so gone that he believes that she left him on purpose while everyone else knows his wife, Phoebe is dead. If he could only find her he believes he could convince her to come home. No one knows how he handled the cold weather, the rain, or other harsh weather. I suppose his love for his wife and hope that he would find out where she had gone would have carried him through the bad weather or it could have been part of his mental illness. In the end the apathetic views of Henry Reifsneider cost Henry his life. One night the old man thought he saw his wife. She looked as she was fifty five years before. He had walked off a cliff and was found laying at the bottom with a smile on his face. He had found his lost Phoebe, as he had promised her he would do if she ever left him. The story of The Lost Phoebe is a perfect example of the new ideas in psychology that influenced the Modernist movement. Theodore Dreiser was interested in the chaotic view of man and it truly shows in this story.

Abstract It can be seen clearly that the Internet has developed with a very high speed in many recent years. In the 80s of last century, the Internet was only used in US army, but nowadays, the Internet has come to every country, every home and everyone. However, such fast develops also go along with the increasing number of security issues from the Internet. Therefore there is a need to find a security solution for this issue and that is the season why Internet Protoco l Securities exists. * In this paper, i will introduce a overview about this security protocol: what is it?What are its core components? And how this protocol was implemented in the practical? II. The need for IPSec 1. Internet threats * The Internet is quickly changing our world, particularly in the way we do business. The fast development of technology has helped to increase the connection speed of Internet and decrease the cost also. This has given the opportunity for people who know how to take advantage of it. The Internet enables such things as: * Extranets: companies can easily link with their business partners and their customers.In the past, we have to use dial up line with low bandwidth, so we have to wait a bit long to get the connection to a web sites or send messages to our friend via yahoo messenger. But today with the quick development of the technology, the speed of the Internet has been increased significantly, therefore the Internet can enable instant and on-demand high-speed communications with our business customers and partners around the world . * Intranets: a powerful tool is widely used for providing the communication in a organization.. Remote users: the Internet also provides a solution for users who don’t need to go to the company till can connect and access to the company network. This will help to reduce the transport cost and also increase the productive of the company. * It can be said that the Internet provides many business opportunities, but if there is not the proper controls, your data can become a subject to various kinds of security attacks. * Loss of Privacy There are many ways that the Internet users can lose their privacy information such as: the address, family information, phone number, credit cards and so on.This information can be used in marketing purposes such as send spam mail about a new product to many people or more dangerously, It can be used for thief or criminal purposes such as: credit care stealing , disclose personal information to the public and so on. * Loss of Data Integrity Even in case your credential is not stolen but there is still need a solution to help ensure the integrity of data. For example, when you do an transaction, your password are not be disclosed but if the number of money of your transaction was modified, you still got a big problem. Identity Spoofing The Internet is an un-trusted network so be careful with your identity when you surf on the Internet because an intruder can impersonate you and get the access to your confidential. * Denial-of-service As organizations take advantage of the Internet, there is a issue that the service being performed is almost always a constant time operation, so it is easy for an external observer process to detect a Dos attack. These attacks are generally transient. 2. TCP/IP security vulnerabilitiesThe main reason lead to Internet threats mentions above is that TCP/IP – the foundation of Internet – has many s ecurity vulnerabilities. When IP, TCP, UDP and the infrastructure protocol of TCP/IP were designed to use in a very small network and all hosts and users are known, hence the security concerns were almost non-existing. But today, with a very quick development of the Internet, there are more and more security vulnerabilities of TCP/IP were exploited. In this section I will reveal an overview about popular kinds of attacks in TCP/IP. a. TCP SYN or TCP ACK Flood AttackThis is a form of DOS attack in which an intruder sends a successful SYN request to victim’s system to consume the resources of the victim’s sever to make the sever cannot respond to the legal connection b. TCP Sequence Number Attack By predicting the IP sequence number, an attacker can inject data or take over a pre-established connection. c. ICMP Attacks Attacker could use either the ICMP message can make a host stop working such as â€Å"Time exceeded† or â€Å"Destination unreachable† messa ges. Attacker can make use of this by simply forging one of these ICMP messages, and sending it to one or both of the communicating hosts.Their connection will then be fallen apart. d. Smurf Attacks The â€Å"smurf† attack is a modification of the classic ping flood attack. An attacker instead of sending ICMP echo packets from his system to the victims network, he send a packet to a broadcast address of middle network with a return IP address of the victim’s network. 3. The need for IPSec To solve issues was mentioned in the previous sections, it is necessary to have a protocol suite which can provide the authentication and decryption to IP packets to increase the security level in data communication over the Internet.And that is reason why we have Internet Protocol Security (IPSec). III. What is IPSec 1. What is IPSec? * Internet Protocol Security (IPSec) has revolutionized Internet Protocol (IP) security. The IPSec protocol suite utilizes cryptographic techniques to ensure data confidentiality, and digital signatures to authenticate the source of the data transmission. IPSec also brings a new level of interoperability to the Internet that never existed before. It doesn’t rely on proprietary protocols or techniques to establish secure links between network nodes.By utilizing IPSec in virtual private networking solutions organizations can exchange sensitive data over public networks with the knowledge that the parties they are exchanging the data with are the intended receivers, that the data was kept confidential in transit, and that the data did not change during transmission. * IPSec has two goals: * To ensure the integrity and confidentiality of IP packets. * To provide a defense against network attacks. Both goals are met through the use of cryptography-based protection services, security protocols, and dynamic key management. 2. IPSec properties IPSec has following properties: * Anti –replay (replay prevention): ensures the un iqueness of each IP packet, any packet was captured by the attacker cannot be put back into the network to establish a session or steal information. * Integrity: protect data from being modified in transit, ensure that received data is the same as the first data. * Confidentiality (encryption): ensures that data is only know by the authorized recipients. To do this, data will be encrypted before being send, and the received has to use a public, private key to decrypt the data when receiving it. Authentication: verifies that a message can only be send from a receiver who knows the shared, secret key. The sender will include a authentication message to the data before sending, the receiver has to use their key to encrypt the authentication message to enable watching the data. If the key is wrong, the data will be discarded. IV. IPSec structure 1. Authentication header (AH) * AH is used to authenticate- but not encrypt – IP traffic, or in other words this protocol guarantees con nectionless integrity and data origin authentication of the packet.Moreover, it can optionally guard against replay attacks by attackers who obtain a copy of authenticated packet and later put it back to the network. * Structure of AH: The AH header consist of 6 parts: * Next hdr (8 bits): this identifies what the upper-level protocol following the AH is * AH len (8bit): this field indentifies the size of the authentication header. * Reserved: this field is a place holder for future use. * Security Parameters Index (32bits): this is a random number that indicates the setting that being selected by the transmitter to communicate with the receiver.This includes the encryption algorithms that are being used, which encryption keys are being used, and the information about the validity period for these encryption keys. * Sequence Number: this is a counter that increases incrementally each time a packet is transmitted using the parameters setup in the SPI. * Authentication Data: this is t he Integrity Check Value(ICV) for the packet. The originator will create a keyed-one-way-hash of the packet payload and attach this hash value to the packet as the authentication field.The receiver can check the integrity of the payload data by hashing the payload data once it has been decrypted with the same hash algorithm, which sender used. If two hash values are identical then the recipient can be sure that the data was not modified during the transmission. However, because the data was not encrypted this does not ensure the confidentiality of the payload data only the integrity. 2. Encapsulating Security Payload (ESP) The ESP is the portions of the IPSec that addresses the confidentiality of the data that is being transmitted as well as offers authentication capabilities.ESP utilizes symmetric encryption techniques to encrypt the IP packet payload. The symmetric encryption algorithms that must be supported in order to be compliant to standard are DES, 3 DES, RSA, CAST, and Blow fish. The ESP will encrypt the IP header or information, which includes the information required for routing. It will only encrypt the packet payload, which will ensure the confidentiality of the data. There are six elements which make up the ESP which include: V. Security Associations (SA) 1. Security Associations * A key issue appears in both authentication and encryption mechanism for IPSec, that is Security Association (SA).SA is a simply the bundle of algorithm are parameters that is used to provide authentication and confidentiality a particular flow of traffic stream in one direction. Thus in normal bi-directional traffic process, the flows are secured by a pair of security associations. * In order to decide what protection is to be provided for an outgoing packet, IPSec uses the Security Parameter Index (SPI), an index to the security association database (SADB), along with the destination address in a packet header, which together uniquely identify a security association fo r that packet.A similar procedure is performed for an incoming packet, where IPSec gathers decryption and verification keys from the security association database. There are two types of SAs are defined: transport mode and tunnel mode. * Transport mode SA is used to provide security communication between two hosts, and in this mode only the payload of packet is encrypted (with ESP) or authenticated (with AH) so it only provide protection for upper layer protocols. A tunnel mode SA is used to provide security communication between two gateway or between a gateway and a host and in this mode the entire IP packet is encrypted (with ESP) or authenticated (with AH). 2. Combining Security Associations * Any single SA can select AH or ESP to protect the data transmits over an IP network but it cannot combine 2 of these protocols. Therefore, there is a need to combine many SAs to achieve the required security policy. The term â€Å"security association bundle† or â€Å"SA bundleâ₠¬  is applied to a sequence of SAs through which traffic must be processed to satisfy a security policy. Security associations may be combined into bundles in two ways: transport adjacency and iterated tunneling. * Transport adjacency refers to applying more than one security protocol to the same IP datagram, without invoking tunneling. This is only applicable for combining AH and ESP at the same level. * Iterated tunneling refers to the application of multiple layers of security protocols affected through IP tunneling. This approach allows for multiple levels of nesting, since each tunnel can originate or terminate at a different IPSec site along the path. Basic ways of SAs’ combination: documents about IPSec structure has listed four cases of combining SAs based on the compatibility between severs or gateways * Case 1: all securities properties are provided between systems. * Case 2: security is only provided between gateways and there is no any host implemented IPSec * Ca se 3: based on the case 2 but add the End to End security. * Case 4: support the remote access through the Internet in the scope of firewalls and expandable accept of server or host in behind the firewalls. 3. SA and key management Key management is an important part of IPSec regarded to identify and distribute the secret key. And basic demand is four keys to communicate between two applications: receiving key and sending keys include two AH and ESP. IPSec structure allows to support two type of key management is: * Manually: every administrator configure manually their private keys with other communicate systems’ keys. In practice, this type of key management is used for small resources in a static environment. * Automated: it is a system which allows creating keys for SAs and being used in a large distribution system with dynamic configuration. The default automated key management in IPSec is called ISAKMP/Oakley with following components: * Oakley key indentifying protocol : Oakley is a basic key exchanging protocol based on Diffie-Hellman algorithm, but added security condition. Oakley is a general standard; it does not have any specific format. * Internet Security Association and Key Management Protocol (ISAKMP): ISAKMP provide a framework for establishing SAs and cryptographic keys in an Internet environment VI. Building a real VPN with IPSec 1. VPN overviewVPN (Virtual Private Network) is the expansion of LAN by adding connections over a shared network or public network like the Internet. In other words, VPN is a private network uses public communication infrastructure but still remains the privacy by using a tunneling protocol and security procedures. VPN can be used to establish a connection between a computer and a private network or between 2 private networks. 2. IPSec in VPN * In IPSec, ESP is the unique way to provide encryption, but ESP and AH both can provide authentication, so what is the most efficient way to combine 2 of them together. The traditional solution of wrapping ESP inside of AH is technically possible, but because of the limitations of AH with NAT (Network Address Translation), hence combining AH and ESP by this way will make this tunnel not work with devices using NAT. * Instead, ESP + Authentication is used in Tunnel mode to fully encapsulate the traffic on its way across an un-trusted network, protected by both encryption and authentication in the same thing. * What's especially nice thing about this way of implement is that VPN and other security measures are almost invisible to the end-user hosts.Because a VPN is carried out by a gateway device which treats the VPN as yet another interface, traffic destined for the other end is routed normally. VII. Future Research This paper only provides an overview about IPSec but not focus on securities components of IPSec such as encryption algorithms and detail of mechanism of SAs. Therefore in the future research I will spend more time on those issues. VIII. Conclusion * After covering most of components of IPSec structure, it can be seen clearly that IPSec is a strong security protocol; it can provide both ncryption and authentications. It also use various types of encryption and authentications algorithm such as Triple-DES, 128 bit C4, AES (for encryption) ; MD5 or SHA-1 (for authentication). * However IPSec still have security issue: when a authorized IPSec user access to the network, they can also access to unauthorized resources. Moreover data file is uploaded and downloaded easily also creates the threats from virus infection. IX. References 1. Www. wikipedia. org 2. http://tools. ietf. org/html/rfc2401#section-4. 4. 3

Marketing Analysis Business Association And Management...

NAGEMENT The focus of any business is to provide needs of customer by providing military and supplies, and in this procedure generate value for customers and solve their trouble. Production and operations management talks about applying big business association and management concepts in formation of supplies and military (1). PRODUCT: A product is defined as the thing offered for deal. A product can be a facility or an item. It can be material or in virtual form. Every product is made with some particular cost and each is sold at a price. The price depends on the quality, marketing etc (2). Product can be different object for different people like for customer product is mix of utilities because customer expects some uses from product.†¦show more content†¦It is that action where by resources, flowing within a defined arrangement, are joint and changed in a controlled manner to add value in according to the policy communicated by management. It does not activate in separation from the other organization system. There exists a feedback about the performance, which is necessary to manage and improve performance of the system. (Schematic production system) CLASIFICATION OF PRODUCTION SYETEM 1. Job-shop production: Job-shop production is used to manufacturing of one or more quantity of any product which is designed and created as per requirement of particular customers within prefixed period and cost. 2.

Changan - Capital of the Han, Sui, and Tang Dynasties

Changan is the name of one of the most important and immense ancient capital cities of ancient China. Known as the eastern terminal of the Silk Road, Changan is located in Shaanxi Province about 3 kilometers (1.8 miles) northwest of the modern town of XiAn. Changan served as capital to the leaders of the Western Han (206 BC-220 AD), Sui (581-618 CE), and Tang (618-907 AD) dynasties. ChangAn was established as a capital in 202 BC by the first Han Emperor Gaozu (ruled 206-195), and it was destroyed during the political upheaval at the end of the Tang dynasty in 904 AD. The Tang dynasty city occupied an area seven times larger than the current modern city, which itself dates to the Ming (1368-1644) and Qing(1644-1912) dynasties. Two Tang dynasty buildings still stand today―the Large and Small Wild Goose Pagodas (or palaces), built in the 8th century AD; the rest of the city is known from historical records and archaeological excavations conducted since 1956 by the Chinese Institute of Archaeology (CASS). Western Han Dynasty Capital At about AD 1, the population of ChangAn was nearly 250,000, and it was a city of international importance for its role as the eastern end of the Silk Road. The Han Dynasty city was laid out as an irregular polygon surrounded by a pounded-earth wall 12-16 meters (40-52 feet) wide at the base and more than 12 m (40 ft) high. The perimeter wall ran a total of 25.7 km (16 mi or 62 li in the measurement used by Han). The wall was pierced by 12 city gates, five of which have been excavated. Each of the gates had three gateways, each 6-8 m (20-26 ft) wide, accommodating the traffic of 3-4 adjacent carriages. A moat provided additional security, surrounding the city and measuring 8 m wide by 3 m deep (26x10 ft). There were eight main roads in Han dynasty ChangAn, each between 45-56 m (157-183 ft) wide; the longest leads from the Gate of Peace and was 5.4 km (3.4 mi) long. Each boulevard was divided into three lanes by two drainage ditches. The middle lane was 20 m (65 ft) wide and reserved exclusively for the use of the emperor. The lanes on either side averaged 12 m (40 ft) in width. Main Han Dynasty Buildings The Changle Palace compound, known as the Donggong or eastern Palace and located in the southeastern part of the city, was approximately 6 sq km (2.3 sq mi) in surface area. It served as the living quarters for the Western Han empresses. The Weiyang Palace compound or Xigong (western palace) occupied an area of 5 sq km (2 sq mi) and was located in the southwestern side of the city; it was where Han emperors held daily meetings with city officials. Its principal building was the Anterior Palace, a structure including three halls and measuring 400 m north/south and 200 m east/west (1300x650 ft). It must have towered over the city, as it was built on a foundation that was 15 m (50 ft) in height at the north end. At the north end of the Weiyang compound was the Posterior Palace and buildings that housed the imperial administration offices. The compound was surrounded by a pounded earth wall. The Gui palace compound is much larger than Weiyang but has not yet been fully excavated or at least not reported in the western literature. Administrative Buildings and Markets In a administrative facility located between the Changle and Weiyang palaces was discovered 57,000 small bones (from 5.8-7.2 cm), each of which were inscribed with the name of an article, its measurement, number, and date of manufacture; its workshop where it was created, and the names of both the artisan and the official who commissioned the object. An armory held seven storehouses, each with densely arranged weapon racks and many iron weapons. A large zone of pottery kilns that manufactured brick and tile for the palaces was located north of the armory. Two markets were identified within the northwestern corner of the Han city of ChangAn, the eastern market measuring 780x700 m (2600x2300 ft, and the western market measuring 550x420 m (1800x1400 ft). Throughout the city were foundries, mints, and pottery kilns and workshops. The pottery kilns produced funerary figures and animals, in addition to daily utensils and architectural brick and tile. In the southern suburbs of Changan were remains of ritual structures, such as the Piyong (imperial academy) and jiumiao (ancestral temples to the Nine Ancestors), both of which were established by Wang-Meng, who ruled ChangAn between 8-23 AD. The piyong was built according to Confucian architecture, a square on top of a circle; while the jiumiao was built on the contemporary but contrasting principles of Yin and Yang (female and male) and Wu Xing (5 Elements). Imperial Mausoleum Numerous tombs have been found dated to the Han Dynasty, including two imperial mausoleums, the Ba Mausoleum (Baling) of Emperor Wen (r. 179-157 BC), in an eastern suburb of the city; and the Du mausoleum (Duling) of Emperor Xuan (r. 73-49 BC) in southeastern suburbs. Duling is a typical elite Han Dynasty tomb. Within its gated, pounded earth walls are separate complexes for the burials of the emperor and empress. Each interment is centrally located within a gated rectangular surrounding wall and covered by a pyramidal pounded-earth mound. Both have a walled courtyard outside of the burial enclosure, including a retiring hall (qindian) and a side hall (biandian) where ritual activities associated with the buried person were conducted, and where the individuals royal costumes were displayed. Two burial pits contained hundreds of nude life-sized terracotta figures―they were clothed when placed there but the cloth has rotted away. The pits also included a number of pottery tiles and bricks, bronzes, gold pieces, lacquers, pottery vessels, and weapons. Also at Duling was a shared mausoleum temple with an altar, located 500 m (1600 ft) from the tombs. Satellite tombs found east of the mausoleums were built during the rulers dynasty, some of which are quite large, many of them with conical pounded earth mounds. Sui and Tang Dynasties Chang​an was called Daxing during the Sui Dynasty (581-618 AD) and it was founded in 582 AD. The city was renamed Changan by the Tang dynasty rulers and served as its capital until its destruction in 904 AD.   Daxing was designed by the Sui Emperor Wens (r. 581-604) famous architect Yuwen Kai (555-612 AD). Yuwen laid out the city with a highly formal symmetry that integrated natural scenery and lakes. The design served as a model for many other Sui and later cities. The layout was maintained through the Tang Dynasty: most of the Sui palaces were also used by Tang dynasty emperors. An enormous pounded-earth wall, 12 m (40 ft) thick at the base, enclosed an area of approximately 84 sq km (32.5 sq mi). At each of the twelve gates, a fired brick fa ¸ade led into the city. Most of the gates had three gateways, but the main Mingde Gate had five, each 5 m (16 ft) wide. The city was arranged as a set of nested districts: the guocheng (outer walls of the city describing its limits), the huangcheng or imperial district (an area of 5.2 sq km or 2 sq mi), and the gongcheng, the palace district, containing an area of 4.2 sq km (1.6 sq mi). Each district was surrounded by its own walls. Main Buildings of the Palace District The gongcheng included the Taiji Palace (or Daxing Palace during the Sui dynasty) as its central structure; an imperial garden was built to the north. Eleven great avenues or boulevards ran north to south and 14 east to west. These avenues divided the city into wards containing residences, offices, markets, and Buddhist and Daoist temples. The only two extant buildings from ancient Changan are two of those temples: the Great and Small Wild Goose Pagodas. The Temple of Heaven, located south of the city and excavated in 1999, was a circular pounded earth platform composed of four concentric stepped circular altars, stacked on top of one another to a height of between 6.75-8 m (22-26 ft) and 53 m (173 ft) in diameter. Its style was the model for the Ming and Qing Imperial Temples of Heaven in Beijing. In 1970, a hoard of 1,000 silver and gold objects, as well as jade and other precious stones called the Hejiacun Hoard was discovered at Changan. The hoard dated to 785 AD was found in an elite residence. Burials: a Sogdian in China One of the individuals involved in the Silk Road trade that was so central to the importance of ChangAn was Lord Shi, or Wirkak, a Sogdian or ethnic Iranian buried in ChangAn. Sogdiana was located in what is today Uzbekistan and western Tajikistan, and they were responsible for the central Asian oasis towns of Samarkand and Bukhara. Wirkaks tomb was discovered in 2003, and it includes elements from both Tang and Sogdian cultures. The underground square chamber was created in the Chinese style, with access provided by a ramp, an arched passageway and two doors. Inside was a stone outer sarcophagus measuring 2.5 m long x 1.5 m wide x 1.6 cm high (8.1x5x5.2 ft), lavishly decorated with painted and gilded reliefs depicting scenes of banquets, hunting, travels, caravans, and deities. On the lintel above the door are two inscriptions, naming the man as Lord Shi, a man of the nation of Shi, originally from the Western countries, who moved to Changan and was appointed sabao of Liangzhou. His name is inscribed in Sogdian as Wirkak, and it says that he died at the age of 86 in the year 579, and was married to the Lady Kang who died one month after him and was buried by his side. On the southern and eastern sides of the coffin are inscribed scenes associated with the Zoroastrian faith and in Zoroastrian fashion, the selection of the south and eastern sides to decorate corresponds to the direction the priest faces when officiating (south) and the direction of Paradise (east). Among the inscriptions is the priest-bird, which may represent the Zoroastrian deity Dahman Afrin. The scenes described the Zorastrian journey of the soul after death. Tang Sancai Pottery Tang Sancai is the general name for vividly color-glazed pottery produced during the Tang dynasty, especially between 549-846 AD. Sancai means three colors, and those colors refer typically (but not exclusively) to yellow, green and white glazes. Tang Sancai was famous for its association with the Silk Road--its style and shape were borrowed by Islamic potters at the other end of the trade network. A pottery kiln site was found at ChangAn named Liquanfang and used during the early 8th century AD. Liquanfang is one of only five known tang sancai kilns, the other four are Huangye or Gongxian Kilns in Henan Province; Xing Kiln in Hebei Province, Huangbu or Huuangbao Kiln and Xian Kiln in Shaanxi.
